Description

Technical Field

[0001] This utility model relates to the field of sewage treatment technology, specifically to a centralized domestic sewage treatment device. Background Technology

[0002] With the further strengthening of new rural construction, centralized treatment and discharge of rural sewage has become a new issue. In rural areas, sewage is mainly domestic wastewater, which was previously discharged directly into streams and rivers without treatment, seriously affecting water quality and the environmental landscape. Therefore, a centralized domestic sewage treatment system is needed to address these problems.

[0003] The prior art, application number CN201821117775.7, discloses a centralized domestic sewage treatment device. This invention mixes injected sewage with flocculant in a stirring chamber to promote sedimentation. It also includes a cleaning water pipe; a water pump delivers water from the storage chamber to the cleaning water pipe and sprays it from nozzles to backwash the inclined tube settler, making cleaning convenient. However, the aforementioned centralized domestic sewage treatment device uses a filter screen at its inlet, which can become clogged over time, requiring frequent cleaning. Furthermore, replacing the built-in filter element is inconvenient, and the filtration efficiency decreases significantly after prolonged use, affecting water quality. Therefore, this invention aims to address these problems. Utility Model Content

[0031] Figures 1-4 The diagram shown is a structural schematic of the first embodiment of a centralized domestic sewage treatment device according to this utility model. Please refer to [link / reference]. Figures 1-4 The main body of the centralized domestic sewage treatment device of this embodiment includes a shell 100.

[0032] The housing 100 is provided with a stirring chamber 110, a sedimentation chamber 120, a filtration chamber 130 and a clear water chamber 140. The top of the stirring chamber 110 is provided with a water inlet 160. The water inlet 160 is provided with a filter cleaning assembly 200. The filter cleaning assembly 200 includes a coarse filter screen 210, a fine filter screen 220 and a turbine 230. A shaft 240 is connected to the turbine 230 and a cleaning blade 250 is installed on the shaft 240. The filtration chamber 130 is provided with a support frame 131 and a filter assembly 300 is installed on the support frame 131. The filter assembly 300 includes a mounting frame 310. A threaded rod 330 is connected to the mounting frame 310. A fixing block 340 is connected to the upper part of the threaded rod 330. A rotating sleeve 350 is rotatably connected to the fixing block 340. A filter core material 360 is installed on the mounting frame 310.

[0033] The shell 100 is used to open the stirring chamber 110, sedimentation chamber 120, filtration chamber 130 and clear water chamber 140. The bottom of the stirring chamber 110 is connected to the sedimentation chamber 120, the top of the sedimentation chamber 120 is connected to the filtration chamber 130, and the bottom of the filtration chamber 130 is connected to the clear water chamber 140. The inclined tube sedimentator 121 is made of ethylene propylene copolymer, fiberglass or polyvinyl chloride honeycomb inclined tube with an inclination angle of 60°, an inclined length of 1m, and an inscribed circle diameter of 35-50mm. The inscribed circle diameter can be changed according to the water quality to achieve the best sedimentation effect. The support frame 131 is used to support the filter assembly 300. The cover plate 132 is used to facilitate the removal of the filter assembly 300. The stirring rod 150 is used to stir the stirring chamber 110 to make the chemical solution and sewage fully mixed. The inlet 160 is used to discharge sewage into the stirring chamber 110, and the garbage outlet 170 is used to discharge the garbage in the inlet 160.

[0034] The filter cleaning assembly 200 is used for preliminary filtration of sewage to prevent large debris from affecting the sewage purification effect. The water flows through the coarse filter screen 210 and the fine filter screen 220 to perform preliminary filtration of debris in the sewage, and then enters the turbine 230. The turbine 230 drives the shaft 240 to rotate by the water flow. When the shaft 240 rotates, it pushes the debris filtered on the coarse filter screen 210 and the fine filter screen 220, and discharges it through the debris outlet 170. Compared with the prior art, it realizes automatic cleaning of debris and prevents debris from clogging the filter screen.

[0035] The filter assembly 300 is used to further filter the settled wastewater through the filter core material 360. The mounting bracket 310 is used to support the filter core material 360 and is connected to the support frame 131. The connecting rod 320 is used to connect the two mounting brackets 310. The threaded rod 330 is used to cooperate with the rotating sleeve 350 to realize the lifting and lowering of the mounting bracket 310. When the rotating sleeve 350 rotates, the threaded rod 330 lifts and lowers. The lifting and lowering of the threaded rod 330 drives the mounting bracket 310 to lift and lower. When the mounting bracket 310 rises to the limit, the filter core material 360 is taken out through the opening at the cover plate 132, so as to facilitate the replacement of the filter core material 360.

[0036] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
