Screw Type Sludge Dehydrator System Recycle Fiber In Papermaking Industry

Sludge Dewatering Machine

The Dehydrator Is Used To Recycle Fiber From Sludge Dewatering Machine In Papermaking Industry

Sludge Dewatering Machine Description

Sludge Dewatering Machine is a new solid-liquid separation equipment which uses the principle of screw extrusion, through the strong extrusion pressure generated by the change of screw diameter and pitch, as well as the tiny gap between the moving ring and the fixed ring, to achieve the extrusion and dewatering of sludge.

Working Principle

Sludge Dewatering Machine is composed of a screw stack, a driving device, a filtrate tank, a mixing system and a frame. Folding screw sludge dewatering machine is working, through the sludge pump sludge after ascending to the mixing tank, at this point, the dosing pump also quantitatively to transport liquid mixing tank, mixing motor drive the mixing system with liquid sludge fully mixing, resulting in a alum flowers, when the liquid level reaches the liquid level sensor is superior, the liquid level sensor signals, make fold screw main motor working, In this way, the sludge is filtered into the main body of the stack screw. Under the action of the spiral shaft, the sludge is lifted to the sludge outlet step by step, and the filtrate flows out from the gap between the fixed ring and the swimming ring.

Advantage

Advantage one: treatment of low concentration sludge

The recommended sludge concentration is between 2000mg/L and 5000mg/L

Equipped with proprietary rotary disc pre-concentration device, it is better at dealing with low concentration sludge, improves the shortcomings of existing gravity concentration, and realizes high efficiency concentration of low concentration sludge.

The integration of flocculation and concentration is completed, and the subsequent dehydration pressure is reduced. Combined with the adjustment of the expansion valve, the slurry concentration can be adjusted to a better state of dehydration.

Advantage two: self-cleaning, no blockage

Dynamic fixed ring replaces filter cloth, self-cleaning, no blockage, easy to handle oily sludge

Under the rotating action of the screw shaft, the movable plate is continuously staggered with respect to the fixed plate, so as to realize the continuous self-cleaning process and avoid the blockage problem commonly existed in the traditional dehydrator. Therefore, the ability to resist oil pollution is strong, easy to separate and not blocked. And it's not equipped with a water cannon.

Advantage three: low noise, low energy consumption

Energy saving and emission reduction, reduce noise pollution

The spiral sludge dehydrator can operate at a low speed of 2-4 RPM by relying on large equipment such as storage dewatering and barrel dispensing. Therefore, the function to achieve low energy consumption, low water consumption, low noise. The average energy consumption is only 1/8 of the belt machine and 1/20 of the centrifuge, and the unit energy consumption is only 0.01-0.1 kwh/kg-DS, which can reduce the operation cost of the sewage treatment system.

Chengdu Yuanjin Environmental Protection Engineering Co., Ltd. is located in Tianfu New District, a national new district in Sichuan Province, and Chengdu Yida Tianfu Smart Science and Technology City. The company has a group of professional technical teams engaged in water environment treatment for a long time, which can provide targeted design schemes. Its own production workshop directly manufactures equipment according to the design requirements, and the prefabricated equipment in the workshop is directly sent to the construction site for installation and commissioning. It is an environmental protection supplier that can provide professional environmental protection equipment manufacturing and housekeeping technical services in design, manufacture, installation, commissioning and operation.

The company is a high-tech enterprise, with professional contracting qualification of environmental protection engineering, second-class qualification of domestic sewage and automatic monitoring operation ability, 7 national authorized patents, 9 computer software copyrights, ISO quality management certification system and other qualifications and honors.

The water treatment equipment produced by the company covers domestic sewage, medical wastewater, landfill leachate, reclaimed water reuse, pure water preparation and other fields, which can meet the national, local and industrial discharge and use standards and different needs of customers.

The company has four series of integrated sewage treatment equipment, namely AT·Jin sewage treatment integrated reactor, DT·Jin sewage treatment integrated reactor, PT·Jin sewage treatment integrated reactor and MINI·Jin sewage treatment integrated reactor. Prefabricated pumping station, reclaimed water reuse and pure water preparation are all systems.

AT·Jin sewage treatment integrated reactor is a series of products adopting "AAO+ tubular membrane" process. After biochemical treatment, sewage enters the third generation external ceramic tubular membrane, and under certain pressure, macromolecular particles larger than 0.1 micron are trapped by the nano-pore filtration function of the membrane. The flux of tubular membrane is 3~10 times that of organic membrane, and its service life is 10 years, which is 3~5 times that of organic membrane.

DT·Jin sewage treatment integrated reactor is a series of products adopting "AAO+MBR" process. After anaerobic, anoxic and aerobic biochemical treatment, the sewage enters the built-in MBR membrane pool for membrane filtration, and the hollow fiber membrane wall is covered with micropores. Under the action of aeration, the sewage accelerates to flow outside the hollow fiber, and forms dynamic negative pressure filtration under the suction of self-priming pump, which does not block the membrane surface and can run continuously for a long time. Macromolecular particles are trapped in the micropores of the membrane, and clear water enters the membrane filaments through the micropores, and is pumped into the clear water pool by a self-priming pump.

PT·Jin sewage treatment integrated reactor, first of all, through biochemical treatment in anaerobic tank and aerobic tank, biological filler is added into aerobic tank, bacteria micelle, filamentous bacteria, etc. grow into microcolony on the filler, and finally a biofilm with a certain thickness is formed. The oxygen content inside and outside the biofilm is different, which produces nitrification and denitrification to purify sewage. The biofilm will gradually fall off after aging, and the released bacteria will form a new biofilm on the surface of the filler again, and the biochemical cycle treatment will continue. After that, chemical dephosphorization is added to the effluent, which enters the inclined tube sedimentation tank to effectively separate the mud and water.

MINI·Jin sewage treatment integrated reactor, with small equipment size, flexible layout of internal space and various shapes, is a small equipment for rural sewage treatment.

The integrated pumping station is the lifting equipment for lifting sewage, rainwater, drinking water and wastewater, which is assembled by the factory and then transported to the site for installation. With highly integrated equipment, convenient installation and prefabricated workshop, it is gradually replacing the traditional civil pump house, which is the second generation of high-efficiency and energy-saving products.

The preparation of pure water and the reuse of reclaimed water are treated by ultrafiltration and reverse osmosis processes. According to the application approaches and standard requirements, single membrane, double membrane, one-stage and multi-stage configurations are carried out, which are used in high-standard fields such as drinking water and industrial soft water.

The water treatment equipment produced by the company is equipped with PLC control system, which can realize remote control and unattended operation, thus saving worry and effort for customers.

The company's integrated water treatment equipment, installation and operation projects are widely used in the southwest and northwest regions. In the past three years, the annual output value has increased by more than 10 million yuan, which has established a good reputation in the industry. Chengdu Yuanjin Environmental Protection Engineering Co., Ltd. adheres to the business philosophy of "focusing on sewage treatment, reappearing clear water and clearing the source", constantly improves its professional ability, develops and updates its product series, improves its quality service, and strives to build a first-class brand in the industry, helping the construction of national ecological civilization and guarding our common home!
