Efficient sludge squeezing dehydrator

Abstract

The invention discloses an efficient sludge squeezing dehydrator which comprises a precipitation dehydration mechanism, a filter cartridge dehydration mechanism and a push plate squeezing mechanism. The precipitation dehydration mechanism comprises a precipitation chamber, a feeding pipe is arranged on one side of the precipitation chamber, and first water outlet grooves are formed in the two sides of the upper end of the precipitation chamber. The filter cartridge dehydration mechanism comprises a filter cartridge, the filter cartridge is communicated with the bottom of the precipitation chamber, the outer side of the filter cartridge is sleeved with a water accumulation chamber, and the water accumulation chamber is communicated with a water outlet pipe. The push plate squeezing mechanism comprises a squeezing chamber, a filter sieve plate is arranged at the upper end of the squeezing chamber, a mud outlet is formed in one side of the upper end of the squeezing chamber, and a baffleis arranged on the mud outlet. According to the invention, sludge containing more moisture is dewatered by adopting the precipitation dehydration mechanism, the filter cartridge dehydration mechanismand the push plate squeezing mechanism, so that the efficiency is higher, the moisture in the sludge can be effectively removed, and further treatment is facilitated.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a high-efficiency sludge press dehydrator. Background technique [0002] Sludge is a solid sedimentary substance produced in the process of water and sewage treatment. The main characteristics of sludge are high water content (up to 99%), high content of organic matter, easy to rot and smell, and fine particles, small specific gravity , in a colloidal liquid state. Due to the high water content, it is inconvenient to process. Therefore, it is necessary to separate the water in the sludge to facilitate subsequent treatment and purification. In the prior art, the sludge dehydration is simple, just through After simple sedimentation and filtration, it is directly transported to the press belt for pressing, resulting in excessive pressure during the operation of the press belt, which cannot effectively dehydrate, resulting in low dehydration efficiency.

[0002] Sludge is a solid sedimentary substance produced in the process of water and sewage treatment. The main characteristics of sludge are high water content (up to 99%), high content of organic matter, easy to rot and smell, and fine particles, small specific gravity , in a colloidal liquid state. Due to the high water content, it is inconvenient to process. Therefore, it is necessary to separate the water in the sludge to facilitate subsequent treatment and purification. In the prior art, the sludge dehydration is simple, just through After simple sedimentation and filtration, it is directly transported to the press belt for pressing, resulting in too much pressure during the operation of the press belt, which cannot effectively dehydrate, resulting in low dehydration efficiency.
