Description

Technical Field

[0001] The invention relates to the technical field of sludge treatment, and in particular to a sewage treatment device for water supply and drainage which is convenient for sludge discharge. Background Art

[0002] Industrial wastewater is often mixed with sludge. During the transportation process, the continuous accumulation of sludge can easily cause blockage. Therefore, the sludge needs to be removed and the wastewater and sludge need to be stored separately for treatment.

[0003] The current processing method has the following disadvantages: 1. The centralized pipeline is used for treatment, which lacks fault tolerance. Once the treatment process is blocked, it will affect the overall treatment of sewage. The diversion method will increase the treatment cost and lack the effect of comprehensive filtration during the transportation process. 2. It is inconvenient to reversely remove the filtered sludge from the treatment structure, and the filter elements need to be maintained separately after continuous operation; 3. Lack of secondary treatment effect makes it inconvenient to remove water for the second time to reduce the water content of the sludge during transportation. Summary of the invention

[0004] In view of this, the present invention aims at the deficiencies existing in the above-mentioned prior art and provides a sewage treatment device for water supply and drainage that is convenient for sludge discharge.

[0007] Optionally, a synchronous shaft and a transmission shaft are rotatably arranged below one side of the diversion channel, the synchronous shaft is installed horizontally, and the transmission shaft is installed vertically, and the synchronous shaft and the transmission shaft are connected by a bevel gear transmission.

[0008] Optionally, an output pipe is integrally arranged on the upper side of the sludge bin close to the sludge pool, and the output pipe is inclined downward; a top seat is fixedly arranged on the top of the sludge bin, and a transmission motor is assembled on the top of the top seat. A screw propeller is fixedly connected to the shaft end of the transmission motor, and the screw propeller is located inside the sludge bin.

[0009] Optionally, a front docking ring is fixedly provided at one end of the spiral steel beam close to the water diversion channel, and the front docking ring is rotatably arranged on the outside of the water diversion pipe in cooperation with a sealing bearing.

[0010] Optionally, a rear docking ring is fixedly provided at one end of the spiral steel beam close to the mud conveying bin, and the rear docking ring is rotatably arranged inside the input pipe in cooperation with a sealed bearing.

[0014] The beneficial effects are as follows: 1. Setting a spiral steel beam provides the function of filtering during the transportation process. The spiral steel beam is driven by a unified power to rotate. The spiral steel beam has a spiral structure and can achieve centrifugal and propulsive effects at the same time. The sewage water passes through the outer filter cartridge and is discharged into the sewage pool. The sludge is pushed into the sludge bin. During transportation, the U-shaped cover can prevent the discharged water from splashing. Multiple sets of spiral steel beams work at the same time, which increases fault tolerance and can efficiently treat sewage.

[0015] 2. Setting up a U-shaped cover can not only provide protection, but also assist in removing sludge. The compressed air is input into the exhaust by the compressor and sprayed out from the air jet. The compressed air is directly blown to the outer filter cartridge, which can push the sludge remaining in the gap of the outer filter cartridge in the opposite direction, remove the sludge, and gradually transport it backwards through the stirring and kneading of the spiral steel beam. By removing the sludge, the service life of the outer filter cartridge is extended, ensuring that the outer filter cartridge can work for a long time.

[0016] 3. The filter plate is set to provide a secondary treatment effect. The sludge is input into the sludge bin through the input pipe and carried by the filter plate. The residual water in the sludge is filtered downward by gravity and discharged into the sewage pool. The transmission motor is started to drive the screw propeller to rotate. The screw propeller generates a propulsion force to transport the sludge upward. The sludge is moved to the output pipe and discharged into the sludge pool for accumulation, thus realizing secondary filtration. The filter plate can be disassembled and replaced after long-term use, and the plug-in installation method is convenient for replacement. BRIEF DESCRIPTION OF THE DRAWINGS
