An integrated sludge dewatering equipment

Abstract

The invention discloses an integrated sludge dewatering device, which relates to the field of sewage treatment devices, and comprises a dewatering body. A filter belt is connected to the inside of the dewatering body through a pair of conveying rollers, and a pressing roller is arranged directly above the middle of the filter belt for dehydration. The device, the pressure roller dehydration device includes a compression rod group, a pressure roller bottom plate and a pressure roller. The dehydration body is provided with a warm air outlet on both sides away from the end of the hopper, and a heater is arranged on the outside of the warm air outlet. In the present invention, the multiple pressure rollers described in the pressure roller dehydration device carry out tight rolling contact with the multiple support rollers under the action of the compression rod group, and at the same time drive the multiple pressure rollers through the drive motor, and are transported by the filter belt. And the sludge passing between the pressing roller and the supporting roller is squeezed, so that the moisture inside is released; when the heater is working, the sludge transported by the filter belt is dried through the warm air port, and the squeezed sludge is further dried. The sludge is dried to improve the drying efficiency.

Description

Technical field [0001] The present invention relates to the field of waste water treatment apparatus, particularly to an integrated sludge dewatering equipment. Background technique [0002] Sewage treatment apparatus is mainly used for waste water treatment, sewage in the liquid phase and solid phase separation, after the sewage is completed, the separated supernatant and sludge are discharged, but also often performed for sludge rich in mineral elements concentrated, conventional wastewater treatment sludge discharge device means lower productivity, increasingly difficult to cope with the amount of sewage processing tasks; and sludge is dewatered mechanically still contain some not dry off moisture, the removal of the dry sludge handling and transportation, will increase the cost of certain treatment. [0003] Also employed in the prior art low pressure enclosure cover sludge process efficiency, and close the package needs to be interrupted, an open double-row roller to press a...

AI Technical Summary

Problems solved by technology

[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
