Screw press sludge dewatering introduction
The sludge dewatering press is an enclosed high performance sludge dewatering system. It utilizes a central screw auger and a slowly oscillating multi-disk filter to gradually increase pressure on flocculated sludge to produce an exceptionally dry sludge cake. With electrical, water and polymer usage, and high capture rates the system is very cost effective.
The sludge dewatering press can be provided with all equipment required for sludge dewatering included and factory mounted, piped and wired on a single stainless steel skid. This equipment includes the sludge pump, wash water pump, polymer dosing system and control panel. The system features fully automated one pushbutton startup and shutdown. Once started up the system can run unattended and can be set to shutdown automatically with no operator intervention.
volute sludge dewatering press structure principle
� The main part of the dehydrator is a volute sludge dewatering press that a screw runs through the stacked fixed rings and moving ring.
� The small gaps between fixed rings and moving ring can filter the sludge, and the lumen between screw and rings is filled with polymer grains. The moving ring transfers the sludge to the end of the machine with pressure and extrudes sludge cakes.
 Layers of the spacers, which are fixed and moving rings, are secured in place by a tie rod. The inner diameters of the moving rings are slightly smaller than the outer diameter of the screw and their rings. Mobilized by the screw, it continuously cleans the sludge out of the gaps, therefore, preventing clogging.
The running of the volute sludge dewatering press the moving ring to clean the gaps and avoid jam.
1. Force-water cocurrent. Force and water are in the same direction, making the free water comes out at the fastest speed.
2. Extension of deatering path. Not only ensuring the amount of time during the process of sludge dewatering, but also ensuring the continuous operation.
3. Moderate pressure. Maintain lowest energy consumption and mechanical wear while ensuring the sludge dewatering effect.
4. Thin-layer dewatering. Thinning the sludge to make the free water come out by going a shorest distance.

General Introduction The Screw sludge dewatering machine, also known as the screw sludge dewatering machine, sludge treatment equipment ,sludge extruder ,sludge extrator ,etc. is a kind of water treatment equipment widely used in municipal sewage treatment projects and industrial industries such as petrochemical, light industry, chemical fiber, paper making, pharmaceutical, leather and so on. Application field The sludge dewatering machine/sludge dehydrator are widely used in below fields: 1. Applicable to municipal sewage, food, beverage, chemical, leather, welding material, paper making, printing and dyeing, pharmaceutical and other industries of sludge. 2. Suitable for dewatering of high and low concentration sludge. When dewatering low-concentration (2000mg/L~) sludge, there is no need to build enrichment tank and storage tank, so as to reduce the construction cost and reduce the release of phosphorus and the generation of anaerobic odor.
machine screw volute sludge dewatering press for sludge dewatering treatment The spiral type sludge dewatering machine is a kind of water treatment system, which is widely used in municipal wastewater treatment engineering, petrochemical, light industry, chemical fiber, paper making, pharmaceutical, leather and other industries. The actual operation shows that the sludge dewatering can create considerable economic benefits and social benefits for the customers. Features 1. Automatic continuous operation 2. Compact design with flocculation and dewatering 3. Low power and water consumption 4. Low operation cost 5. No filter cloth, no clogging 6. No need for sludge thickener 7. Easy operation and maintenance 8. No vibration and noise
Main Parts: Sludge concentration & dewatering Body; Flocculation & Conditioning Tank; Integrate Automatic Control Cabinet; Filtrate Collection Tank Working Principle: Force-water concurrent; Thin-layer dewatering; Moderate press; Extension of the dewatering path It has solved several technical problems of other similar sludge dewatering equipment including belt presses, centrifuge machines, plate-and-frame filter press have, which are frequent clogging, low concentration sludge / oil sludge treatment failure, high energy consumption and complicated operation etc Thickening: When the shaft is driven by the screw, moving rings around the shaft move up and down relatively. Most water is pressed out from the thickening zone and fall down to the filtrate tank for gravity. Dewatering: The thickened sludge moves forward continuously from the thickening zone towards the dewatering zone. With the pitch of the screw shaft thread getting narrower and narrower, the pressure in the filter chamber increases higher and higher. In addition to the pressure generated by the back-pressure plate, the sludge is greatly pressed and dryer sludge cakes produce. Self-cleaning: The moving rings rotates continuously up and down under the pushing of the running screw shaft while the gaps between the fixed rings and moving rings are cleaned to prevent from clogging that happens frequently for traditional dewatering equipment. Product Feature: Special pre-concentrating device, wide feed solids concentration: 2000mg/L-50000mg/L The dewatering part of MSP consists of a thickening zone and a dewatering zone. In addition, a special pre-concentrating device is mounted inner the flocculation tank. Therefore, the wastewater with rather low solids content is not a problem to MSP. The applicable feed solids concentration can be as very wide as 2000mg/L-50000mg/L. Since MSP can be used directly to concentrate and dewater the low-solid sludge from aeration tanks or secondary clarifiers, the users don't have to build a thickening tank or a storage tank any more while they have to when using other types of sludge dehydrators, especially the belt filter presses. Then significant civil engineering cost and floor area are saved.
Sludge Dewatering Screw Type Press Machine has the following characteristics 1.Suitable for sludge dewatering of high/low consistency. 2.There is no need to worry about jam up. Reduce the cleaning water consumption. 3.The electrical cabinet, disposal tank and dehydrator are integrated, which reduces the covering area and brings convenience to installment. 4.The dehydrator is enclosed working, which reduces the bad smell and improves the working environment. 5.Automatically working for 24 hours, reducing the labor strength of workers. 6.The slow running speed of screw shaft reduces the power consumption and noise. 7.It is made with stainless, extending the service life. 8.It is convenient for daily maintenance.

Since chemical sludge components are very complex, it is very harmful to landfill. It must be dried before further treatment. Due to its complicated contents, it is very hard to dry. This rotary drum dryer is specifically designed for such sticky chemical sludge. According different viscousity and moisture contents, it can use double-helix or triple-helix rotary harrows to make sludge fully contact with hot air and get it flash-dried in surface, which efficiently prevents sludge cling to the dryer. In the first cylinder, the sludge water evaporation is faster, so the hot air temperature dropped sharply. To avoid the water being absorbed again, the waste hot air and evaporation will be discharged directly in the end. There are special guiding and lifting boards, which makes dry sludge transfer faster, wet sludge slower. Through the way, sludge will be dried evenly as requirement and dont need to be re-dried like traditional drying equipment. So, inquire for details, try and buy.
