Screw press is a kind of equipment that uses physical extrusion to dehydrate. The material box enters the equipment and is squeezed step by step under the conveying of the screw auger. The excess water is discharged from the liquid outlet through the screen. The discharge port discharges the equipment. The screw press produced by our company has undergone hundreds of accurate theoretical derivation calculations and experimental tests, summed up the real effect feedback of many users in the process of using it for many years, and upgraded it to a series of mature equipment in an all-round way. Different technical parameters can truly achieve low energy consumption, high output, and low moisture, saving a lot of processing costs for the secondary recycling of materials.
The screw sludge dewaterinng machine belongs to the screw press, it's clog-free and can reduce the sedimentation tank and sludge thickening tank, saving the cost of sewage plant construction. Using screw and the moving rings to clean itself as clog-free structure, and controlled by the PLC automatically, it's a new technology that can replace the traditional filter press like belt press and frame press, the screw speed is very low, so it cost low power and water consumption in contrast to the centrifuge, it is a cutting edge sludge dewatering machine.It concentrates and dehydrates sewage directly in 24 hours continuously and efficiently with self-service operating and greatly reduces the cost of design,construction,operation maintenance and management.
The purpose of animal feed drying is to remove the excess water from the feed stock for easy to pack, transport, store, process and use. In view of the animal feed is high humid and viscous, we designed Rotary Harrow Rolling Triple Stage & Multiple-loop Drying Equipment. It uses unique design concept and truly energy saving technology. With the 1 + 3 = 6 three cylinders technology, 3 * 6 = 36 S Type material moving processes, 6 - 3 = 1 fast air exhausting way and Moving forward 3 steps and backward 2 Reciprocating drying method, the dryer operating like a Smart Robot. In the operation of moving forward, backward, directing, conversing, raising, turning, the material contacts with the hot air efficiently, thereby being dried quickly and evenly. Dry material will be discharged into star type unloader, then unload on conveyor for next operation (mixing, cooling and package). The whole process is automatically and controlled by PLC. Equipment operation only need 1-2 people per shift. This drying equipment can also be used for drying forage, distillers grain, cassave residues/pulp, corn pulp, potato dregs, soy sauce residue, soybean wastes, fruit pomace, zymophyte dregs etc. The finished production is very good raw material of organic feed for animals.
"The electroplating sludge contains lots of heavy metal which is harmful to environment and health. It is banned to landfill or dump directly. So it is necessary to dry firstly. Whats more, some plating sludge have precious metal, after drying it can be recycle and use. We use advanced triple pass rotary drum multi-loops drying technology, which can dry sludge below 10% mositure content. Nowadays, above 90 % electroplating factories use ZJN Drying Equipment in China for electroplating sludge. We have over 20-year drying machine manufacturing experience, specialized in customizing the most engergy saving and efficient dryers. "
Multidisc are arranged one after other with alternate disc being moving and fixed. The gap between the plates acts as media for fine filtration. The screw press main unit requires very very low power motor and the filtration surface area consists of a multiple discs which are self-cleaning, and generally do not clog,thus, the sludge press can be used continuously.The main unit of the sludge dewatering screw press is of multi-shaft design. Hence, when two or more main units are configured into one machine, any individual shaft can be repaired or serviced without interrupting operations.
Multi-Disk Screw Press (MDS) is one kind of screw press, it's clog-free and can reduce the sedimentation tank and sludge thickening tank, saving the cost of sewage plant construction. MDS using screw and the moving rings to clean itself as clog-free structure, and controlled by the PLC automatically, it's a new technology that can replace the traditional filter press like belt press and frame press, the screw speed is very low, so it cost low power and water consumption in contrast to the centrifuge, it is a cutting edge sludge dewatering machine.
Screw Press Screw press is designed for dewatering of film plastics, organic fraction of and refuse derived fuel from municipal solid waste,restaurant waste and digestate from high solid anaerobic digestor, etc. In general, the screw press separates a liquid or pasty phase from a well-structured coarse solid.
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.
