Integrated sludge dewatering device

Abstract

The invention discloses an integrated sludge dewatering device, which relates to the field of sewage treatment devices and comprises a dewatering body, wherein the inside of the dewatering body is connected with a filter belt through a pair of conveying rollers; a pressure roller dewatering device is arranged right above the middle part of the filter belt; the pressure roller dewatering device comprises a compression rod group, a pressure roller bottom plate and a pressure roller; warm air ports are arranged on two sides of the dewatering body far away from one end provided with a hopper; anda warm air blower is arranged close to the outside of the warm air port. In the invention, a plurality of pressure rollers of the pressure roller dewatering device are in tight rolling contact with aplurality of support rollers under the action of a compression rod group, and the plurality of pressure rollers are driven by a driving motor, are transported by a filter belt, and sludge passing between the pressure rollers and the support rollers is squeezed, so that moisture in the pressure rollers is discharged; When the warm air blower works, the sludge transported by the filter belt is driedthrough the warm air port, and the extruded sludge is further dried to improve the drying efficiency.

Description

technical field [0001] The invention relates to the field of sewage treatment devices, in particular to an integrated sludge dewatering device. Background technique [0002] Sewage treatment equipment is mainly used for sewage treatment to separate the liquid phase and solid phase substances in the sewage. After the sewage treatment is completed, the separated clear night and sludge are discharged separately. For sludge rich in mineral elements, it is often necessary to Concentration, but the working efficiency of the sludge discharge device of traditional sewage treatment equipment is low, and it is difficult to cope with the increasing amount of sewage treatment tasks; and the dehydrated sludge still contains some water that cannot be dehydrated mechanically. When the dried sludge is processed and transported, a certain processing fee will be added. [0003] In addition, in the prior art, the efficiency of using the method of compressing and covering mud in a closed space...

[0002] Sewage treatment equipment is mainly used for sewage treatment to separate the liquid phase and solid phase substances in the sewage. After the sewage treatment is completed, the separated clear night and sludge are discharged separately. For sludge rich in mineral elements, it is often necessary to Concentration, but the working efficiency of the sludge discharge device of the traditional sewage treatment equipment is low, and it is difficult to cope with the increasing amount of sewage treatment tasks; and the dehydrated sludge still contains some water that cannot be dehydrated mechanically. When the dried sludge is processed and transported, a certain amount of processing costs will be added

[0003] In addition, in the prior art, the efficiency of using the method of pressing and covering the mud in a closed space is low, and the closed packaging needs to be interrupted. The use of the open double-row roller dynamic pressing and water removal method makes it easy for the mud to be squeezed for the first time. In the gap, such as the free area between two rollers, the water squeezed out is reabsorbed, making the pressing efficiency unsatisfactory
