Description

Technical Field

[0001] This utility model is a municipal sewage treatment equipment, belonging to the field of sewage treatment. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.

[0003] The existing municipal wastewater treatment system has a drawback: most of these systems use filters to remove impurities from the wastewater. However, after prolonged use, the filters are not cleaned regularly, leading to reduced filtration efficiency and even filter clogging. In a municipal sewage treatment device with application number 202420163682.7, the patent uses a drive motor to rotate a threaded rod, which in turn drives a threaded block to move. The threaded block then drives a movable plate to move, which in turn drives a cleaning plate to move. This allows the cleaning plate to automatically clean the surface of the filter screen. The cleaning plate then pushes a baffle through a push rod to open the drain outlet, allowing impurities to be discharged from the outlet. This effectively prevents impurities from clogging the filter screen and improves the efficiency of the filter screen.

[0004] Therefore, the aforementioned patent uses a cleaning plate to clean impurities on the surface of the filter screen to solve the technical problem of not being able to clean the filter screen in a timely manner. However, when the patent uses a cleaning plate to process impurities, some impurities will get stuck in the mesh of the filter screen. It is impossible to clean out the impurities by using only a scraper. Moreover, the filter screen will wear out after a long period of use and needs to be replaced in time, otherwise it will affect the filtration efficiency of the filter screen. Therefore, this utility model proposes a municipal sewage treatment equipment with a detachable filter screen. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a municipal sewage treatment equipment.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: A municipal wastewater treatment device includes a treatment tank, a granulator fixedly mounted on the top of the treatment tank, a wastewater inlet pipe at the top of the granulator, an insertable filter assembly inside the treatment tank, a granulator assembly inside the granulator assembly, the filter assembly including a U-shaped frame, a top-level filter frame installed inside the U-shaped frame, filter screens provided on the inner side of the top-level filter frame and the inner side of the bottom of the U-shaped frame, a middle-level filter assembly placed between the top-level filter frame and the U-shaped frame, the middle-level filter assembly including multiple integrally formed cross frames, filter screens provided on the inner side of the cross frames, an agitator at the bottom of the treatment tank, a drive motor for driving the agitator mounted on the outer wall of the treatment tank, multiple drain pipes at the bottom of the treatment tank, and an outer sealing plate fixedly mounted on one end of the U-shaped frame, the outer sealing plate being fixed to the outer surface of the treatment tank with screws.

An outer sealing plate three is fixed on one side of the double-layer activated carbon filter plate, and the outer sealing plate three is fixed to the outer surface of the treatment box with screws.

[0011] Furthermore, rubber sealing gaskets are attached to the end faces of outer sealing plate three, outer sealing plate one, and outer sealing plate two, and the sealing gaskets are in the shape of a square.

[0012] Furthermore, multiple L-shaped mounting brackets are fixed at both ends of the top filter frame. The U-shaped frame has recessed grooves that match the L-shaped mounting brackets, and the L-shaped mounting brackets are fixed in the recessed grooves with screws.

[0013] Furthermore, the crushing assembly includes two cutting rods rotatably disposed inside the particle crushing chamber. The outer surface of the cutting rods is equipped with cutting blades, and cutting motors for driving the cutting rods are respectively provided on the outer wall of the particle crushing chamber.

[0014] The beneficial effects of this utility model are: By connecting the sewage inlet pipe to the external sewage outlet pipe, the sewage is discharged into the particle crushing box for particle crushing, thus ensuring the subsequent filtration effect.

[0015] Wastewater is filtered in multiple layers through filter screen one and filter screen two inside the cross frame. This multi-layer filtration improves the filtration effect. The filter components are detachable and can be inserted into the treatment box. The filter components inside the treatment box can be periodically removed to treat the impurities after the wastewater has been filtered.

[0016] The agitator is driven by a motor to rotate, and the purification agent added inside the treatment tank is stirred and dissolved by the agitator, causing the filtered wastewater to mix with the purification agent. This allows the agent and wastewater to react fully, purifying the wastewater. Finally, the purified water is discharged through the drain pipe. This invention is simple to set up, allows for regular treatment of filtered impurities, and manual cleaning ensures that the impurities on the filter components are removed more thoroughly. Furthermore, the addition of the agent to mix with the wastewater further improves the wastewater purification effect. Attached Figure Description

[0021] Please see Figure 1-5 This utility model provides a municipal sewage treatment equipment, including a treatment tank 1, a particle crushing box 2 fixedly installed at the top of the treatment tank 1, a sewage inlet pipe 3 installed at the top of the particle crushing box 2, a filter assembly inserted into the treatment tank 1, a crushing assembly installed in the particle crushing box 2, the filter assembly including a U-shaped frame 4, a top layer filter frame 5 installed in the U-shaped frame 4, filter screens 6 installed on the inner side of the top layer filter frame 5 and the inner side of the bottom end of the U-shaped frame 4, a middle layer filter assembly placed between the top layer filter frame 5 and the U-shaped frame 4, the middle layer filter assembly including multiple integrated cross frames 7, filter screens 2 installed on the inner side of the cross frames 7, a stirrer 8 installed at the bottom of the treatment tank 1, a drive motor for driving the stirrer 8 installed on the outer wall of the treatment tank 1, multiple drain pipes 9 installed at the bottom end of the treatment tank 1, an outer sealing plate 11 fixedly installed at one end of the U-shaped frame 4, the outer sealing plate 11 being fixed to the outer surface of the treatment tank 1 with screws.

[0022] See Figure 1-2 The sewage inlet pipe 3 is threaded with a sealing cap, and the drain pipe 9 is equipped with a valve. The treatment tank 1 is also equipped with a feeding pipe 10 with a sealing cap. The agitator 8 includes a drive rod connected to a drive motor. The outer surface of the drive rod is evenly distributed with stirring blades. The feeding pipe 10 facilitates the addition of purification agents into the treatment tank 1. In conjunction with the agitator 8, the filtered sewage is mixed with the purification agents and stirred to dissolve, thereby purifying the sewage.

[0023] See Figure 2A secondary filter assembly is inserted into the treatment tank 1, located between the agitator 8 and the drain pipe 9. The secondary filter assembly includes a double-layer filter frame 12, with a filter screen 3 on the inner side of the double-layer filter frame 12. An outer sealing plate 2 13 is fixed to the top of the double-layer filter frame 12 and is fixed to the outer surface of the treatment tank 1 with screws. The agitator stirs and dissolves the added purification agent, so that the agent reacts fully with the sewage and the sewage is purified. The sewage that meets the purification standard is filtered through the filter screen 3 on the double-layer filter frame 12 and then discharged. The double-layer filter frame 12 is also detachable and can be cleaned regularly to remove impurities.

[0024] See Figure 1 , Figure 3 and Figure 4 A purification box 22 is fixedly installed at the bottom of the treatment box 1. A double-layer activated carbon filter plate 14 is inserted into the purification box 22. An integrated cross-shaped activated carbon filter plate 15 is also installed between the double-layer activated carbon filter plates 14. An outer sealing plate 3 16 is fixed on one side of the double-layer activated carbon filter plate 14. The outer sealing plate 3 16 is fixed to the outer surface of the treatment box 1 with screws. The purified water can be discharged into the purification box 22 and the wastewater is adsorbed and filtered by the double-layer activated carbon filter plate 14 to further improve the filtration effect of wastewater. Finally, the water is discharged. The double-layer activated carbon filter plate 14 is detachable and can be cleaned or replaced regularly.

[0025] See Figure 3-4 Rubber sealing gaskets 17 are attached to the end faces of the outer sealing plate 16, outer sealing plate 11, and outer sealing plate 2 13. The sealing gaskets 17 are U-shaped. The rubber sealing gaskets 17 are attached to the end faces of the outer sealing plates 16, 11, and 2 13, which are also attached to the inner surfaces. This ensures that the outer sealing plates 16, 11, and 2 13 are fixed to the outer surfaces of the treatment box 1 and the purification box with screws. At this time, the rubber sealing gaskets 17 are pressed against the outer surfaces of the treatment box 1 and the purification box to ensure the sealing after installation.

[0026] See Figure 3 and Figure 5Multiple L-shaped mounting brackets 18 are fixed at both ends of the top filter frame 5.

The pulverizing assembly includes two cutting rods 20 rotatably disposed within the particle pulverizing chamber 2. Cutting blades 21 are mounted on the outer surface of the cutting rods 20. Cutting motors driving the cutting rods 20 are respectively provided on the outer wall of the particle pulverizing chamber 2. The cutting blades 21 within the particle pulverizing chamber 2 cut the particles in the wastewater, pulverizing them to ensure the filtration efficiency of subsequent wastewater. As a result, the L-shaped mounting bracket 18 ensures the detachability of the top layer filter frame 5. The cross frame 7 is inserted between the top layer filter frame 5 and the U-shaped bracket 4. The removal of the top layer filter frame 5 facilitates the removal of the cross frame 7. The cross activated carbon filter plate 15 is directly inserted between the double-layer activated carbon filter plates 14, and it is also convenient to pull out the cross activated carbon filter plate 15 later. One end of the cutting rod 20 protrudes from the particle crushing box 2, and a bearing is fitted on the protruding end. The bearing is fixed on the outer wall of the particle crushing box 2. The output shaft of the cutting motor is connected to the corresponding cutting rod through a coupling.

[0027] In use, sewage is discharged into the particle crushing box 2 through the sewage inlet pipe 3 connected to the external sewage outlet pipe for particle crushing, thus ensuring the subsequent filtration effect. The sewage is filtered in multiple layers through the filter screen 6 and the filter screen 2 inside the cross frame 7. The multi-layer filtration can improve the filtration effect. The filter components are detachable and can be inserted into the treatment box 1. The filter components inside the treatment box 1 are periodically removed to treat the impurities after sewage filtration. The drive motor drives the stirrer 8 to rotate. The purification agent added inside the treatment box 1 is stirred and dissolved by the stirrer 8, so that the agent and sewage can fully react and purify the sewage. Finally, the purified water is discharged through the drain pipe 9. This utility model is simple to set up. The periodic treatment of filtered impurities and manual cleaning can ensure that the impurities on the filter components are cleaned more thoroughly. The addition of agents and the mixing of sewage further improve the sewage purification effect. The treatment box and the purification box are connected through the drain pipe. The rubber sealing gasket is made of nitrile rubber.
