Description

Technical Field

[0001] The present invention relates to the technical field of sewage pumps, in particular to an anti-blocking intelligent sewage pump for wastewater treatment. Background Art

[0002] Sewage pumps are widely used in the transportation of liquids containing solid particle suspensions or fibrous suspensions in industries such as municipal, environmental protection, sewage treatment, light industry, chemical industry, mining, petroleum, water conservancy, and metallurgy. They are one of the energy-consuming large users and key equipment in relevant industries.

[0003] According to the publicly disclosed patent CN218844718U, a sewage pump with anti-blocking function is known, which includes a body and a filtering device. A water pipe is arranged on one side of the body, and the filtering device is arranged on one side of the body. The filtering device includes a filter plate, the filter plate is sleeved with the body, one side of the filter plate is fixedly connected with a motor, the driving end of the motor penetrates through the filter plate and is fixedly connected with a brush, and one side of the filter plate is fixedly connected with a fixed block.

[0004] During use, although the existing sewage pump adds a cleaning structure to the filter cover to reduce the blockage of the sewage pump during the suction process, in an environment with a large amount of silt, due to the lack of an effective anti-tilting support structure, the pump body may tilt due to external forces (such as water flow impact). After tilting, the contact area between the filter cover and the silt increases, and the silt accumulates on the inclined surface due to gravity to form a "mud cake" layer, which further causes the filter holes at the inclined part to be completely blocked. This not only increases the operating resistance of the sewage pump but also significantly increases the energy consumption. In addition, the tilting of the pump body may also affect the stability and service life of the sewage pump, increasing the frequency of maintenance and replacement. Summary of the Invention

[0005] In view of the problem in the above or the existing technology that in an environment with a large amount of silt, due to the lack of an effective anti-tilting support structure, the pump body may tilt due to external forces (such as water flow impact). After tilting, the contact area between the filter cover and the silt increases, and the silt accumulates on the inclined surface due to gravity to form a "mud cake" layer, which further causes the filter holes at the inclined part to be completely blocked. This not only increases the operating resistance of the sewage pump but also significantly increases the energy consumption.

[0011] As a preferred embodiment of the anti-clogging intelligent sewage pump for wastewater treatment of the present invention, the following is provided: There are two liquid inlet pipes, and the liquid inlet pipes are symmetrically arranged. A discharge valve is connected to the lower end of the storage spherical shell. A fixed frame is welded to the lower end of the support frame on the side away from the filter cover, and the fixed frame corresponds to the storage spherical shell one by one. A first return spring is fixedly installed inside the fixed frame, and the other end of the first return spring is fixedly connected to the outer wall of the storage spherical shell.

[0012] As a preferred embodiment of the anti-clogging intelligent sewage pump for wastewater treatment of the present invention, the following is provided: The filter cover cleaning assembly includes a second fixed ring arranged above the first fixed ring. A second lead screw sleeve is arranged on the side of the second fixed ring close to the bidirectional lead screw. A fixed frame is arranged below the side of the second fixed ring close to the bidirectional lead screw. Limit frames are welded to the front and rear sides of the liquid outlet pipe. The lower end of the fixed frame passes through the middle of the limit frame and is fixedly connected to a protective cylinder, and the fixed frame is movably connected to the limit frame. The protective cylinder is arranged above the filter cover. A scraping ring is adhered to the lower end of the inner wall of the protective cylinder, and the cross section of the scraping ring is wedge-shaped.

[0013] As a preferred embodiment of the anti-clogging intelligent sewage pump for wastewater treatment of the present invention, the following is provided: The first fixed ring and the second fixed ring are symmetrically arranged. The size of the second lead screw sleeve is adapted to the size of the bidirectional lead screw, and the second lead screw sleeve is threadedly connected to the bidirectional lead screw. Second return springs are sleeved on the front and rear sides of the lower end of the fixed frame. The end of the second return spring close to the limit frame is fixedly connected to the limit frame. The size of the protective cylinder is larger than the size of the filter cover, and the inner side of the scraping ring is in contact with the outer wall of the filter cover.

[0014] The beneficial effects of the anti-clogging intelligent sewage pump for wastewater treatment of the present invention: The present invention can expand the retracted support frame so that the three support frames support under the sewage pump main body. Since the three annularly distributed support frames support under the sewage pump main body, even if the sewage pump main body is tilted, due to the support of the support frame, the inclined contact area between the filter cover on the sewage pump main body and the silt surface will be reduced, thereby reducing the clogging of the filter cover.

[0015] The weight below the pump body can also be increased by three accumulator spherical shells filled with sewage. Since the weights of the three accumulator spherical shells are all concentrated below the filter cover, the center of gravity height of the pump body can be reduced during the operation of the sewage pump main body, thereby improving the anti-tipping performance of the pump body. And by forming an inclined angle between the support frame and the accumulator spherical shell, the gravity of the water in the accumulator spherical shell will generate a downward component force, which will be transmitted to the lower part of the support frame through the inclined accumulator spherical shell, increasing the pressure of the rubber plate on the support frame on the ground, thereby enhancing the friction between the rubber plate on the support frame and the ground. The increase in friction helps to improve the stability of the support frame, enabling the entire support assembly to better resist external forces and prevent the sewage pump main body from tipping over, and further reducing the situation of tipping and blockage of the filter cover below the sewage pump main body.

[0016] The fixed frame can also drive the protective cylinder to move downward. At this time, the protective cylinder moves downward from the upper end of the filter cover. At the same time, the scraping ring inside the protective cylinder will scrape and clean the sewage attachments remaining on the outside of the filter cover. Until the protective cylinder covers the outside of the filter cover, at this time, the bidirectional lead screw is no longer rotated. At the same time, the scraping ring will drive the scraped attachments to move to the lower end of the filter cover and separate from the filter cover, thereby solving the problem that the sewage attachments on the filter cover dry and harden and affect the next use of the sewage pump main body.

[0017] It can also be because the protective cylinder covers the outside of the filter cover, and then the outside of the filter cover can be protected. And in cooperation with the retracted support frame covering the outside of the protective cylinder, a double-layer protection is formed for the filter cover, thereby avoiding the situation of bumping and deformation of the filter cover during transportation.

Detailed implementation manners

[0027] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0028] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude other embodiments.

[0030] Embodiment 1, refer to Figures 1 to 6, which is the first embodiment of the present invention. This embodiment provides an anti-blocking intelligent sewage pump for wastewater treatment, which can reduce the center of gravity height of the pump body during the operation of the pump body, thereby improving the anti-tipping performance of the pump body and further reducing the occurrence of tipping and blocking of the filter cover 102 below the pump body. It includes an anti-tipping mechanism 100, which includes a sewage pump main body 101, and also includes a filter cover 102 arranged below the sewage pump main body 101 for filtering impurities. A first fixing ring 103 is arranged on the outer side of the sewage pump main body 101. The first fixing ring 103 is provided with a support component for anti-tipping support of the sewage pump main body 101, and a storage spherical shell 110 is arranged below the first fixing ring. An inner side of the support component is provided with a lifting component for lifting the storage spherical shell 110. One side of the first fixing ring 103 is provided with a cleaning mechanism 200. The cleaning mechanism 200 includes a filter cover cleaning component arranged on the outer side of the filter cover 102 for cleaning the residual attachments on the surface of the filter cover 102.

[0031] In this embodiment, by controlling the downward movement of the first fixing ring 103, the support assembly on the first fixing ring 103 supports the lower part of the sewage pump main body 101. A triangular stable structure is formed by three inclined support frames 104 to support the lower part of the sewage pump main body 101. At the same time, when the support assembly moves down in place, the lifting assembly inside the support assembly will traction the storage spherical shell 110, so that the storage spherical shell 110 rotates out of the inner cavity of the support assembly and rotates to the lower part of the filter cover 102. Then, after the sewage is poured into the storage spherical shell 110, the weight under the pump body is increased by three storage spherical shells 110 filled with sewage, so as to reduce the center of gravity height of the pump body during the operation of the sewage pump main body 101, thereby improving the anti-tipping performance of the pump body. And by forming an inclined angle between the support frame 104 and the storage spherical shell 110, the gravity of the water in the storage spherical shell 110 will generate a downward component force, and this component force will be transmitted to the lower part of the support frame 104 through the inclined storage spherical shell 110, increasing the pressure of the support frame 104 on the ground, thereby enhancing the friction between the support frame 104 and the ground. The increase in friction helps to improve the stability of the support frame 104, enabling the entire support and anti-tipping assembly to better resist external forces and prevent the pump body from tilting, further reducing the situation of the filter cover 102 under the pump body tipping and blocking. When the sewage pump main body 101 is used up, control the first fixing ring 103 to move upward, so as to retract the support assembly and the storage spherical shell 110, reducing the occupied space of the sewage pump main body 101. At the same time, the cleaning mechanism 200 on the first fixing ring 103 will move relatively, driving the filter cover cleaning assembly to move downward, so that the filter cover cleaning assembly scrapes and cleans the sewage attachments remaining on the filter cover 102, avoiding the drying and caking of the sewage attachments affecting the next use of the sewage pump main body 101. And after the filter cover cleaning assembly finishes cleaning, the filter cover cleaning assembly will cover the outside of the filter cover 102, thereby protecting the outside of the filter cover 102. At the same time, cooperating with the retracted support assembly to cover the outside of the filter cover cleaning assembly, thus forming a double-layer protection for the filter cover 102, avoiding the situation of the filter cover 102 being knocked and deformed during transportation.

[0032] Specifically, the support assembly includes a support frame 104 disposed on the first fixing ring 103. Fixed rods 106 are welded to both the front and rear sides of the sewage pump main body 101. A bidirectional lead screw 107 is disposed on the left side of the sewage pump main body 101. A first lead screw sleeve 108 is disposed on the side of the first fixing ring 103 close to the bidirectional lead screw 107. The size of the first lead screw sleeve 108 is adapted to the size of the bidirectional lead screw 107, and the first lead screw sleeve 108 is threadedly connected to the bidirectional lead screw 107. The filter cover 102 is detachably installed at the lower water inlet of the sewage pump main body 101. The liquid outlet end of the sewage pump main body 101 is communicated with a liquid outlet pipe 118. The liquid outlet pipe 118 is disposed on the side close to the bidirectional lead screw 107. The support frame 104 is provided in three, and the support frame 104 is fixedly installed on the edge of the first fixing ring 103 by welding. A rubber plate 105 is disposed at the lower end of the support frame 104. The fixed rod 106 is movably connected to the first fixing ring 103, and the fixed rods 106 are symmetrically disposed on the front and rear sides of the first fixing ring 103. The lower end of the bidirectional lead screw 107 is rotatably connected to the left side of the sewage pump main body 101 through a bearing. A pressure sensor is disposed in the inner cavity of the liquid outlet pipe 118.

[0033] In this embodiment, the first lead screw sleeve 108 is fixedly connected to the first fixing ring 103 by welding, and the rubber plate 105 is detachably connected to the support frame 104 by bolts. When in use, first rotate the bidirectional lead screw 107 clockwise. The bidirectional lead screw 107 drives the first fixing ring 103 to move downward along the fixed rod 106 through the first lead screw sleeve 108. The first fixing ring 103 drives the support frame 104 to move accordingly, thereby unfolding the retracted support frame 104 and enabling the three support frames 104 to support under the sewage pump main body 101. Since the three annularly distributed support frames 104 support under the sewage pump main body 101, even if the sewage pump main body 101 is tilted, due to the support of the support frame 104, the inclined contact area between the filter cover 102 on the sewage pump main body 101 and the sludge surface will be reduced, thereby reducing the blockage of the filter cover 102.

[0034] It should be noted that since the support frames 104 are set to three and are annularly distributed outside the sewage pump main body 101, a triangular stable structure is formed to support under the sewage pump main body 101, reducing the risk of the sewage pump main body 101 tipping over. Moreover, the side surface of the support frame 104 is also designed to be inclined, ensuring that an inclined angle is formed between the support frame 104 and the sewage pump main body 101, thereby ensuring the support stability of each support frame 104 for the sewage pump main body 101. And due to the setting of the rubber plate 105 on the support frame 104, the contact area and friction force between the support frame 104 and the ground can be further increased, thus improving the anti-tipping effect of the sewage pump main body 101. And a pressure sensor is arranged in the inner cavity of the liquid outlet pipe 118 to monitor the pressure situation inside the liquid outlet pipe 118 through the pressure sensor. The pressure sensor transmits the signal to the control system, thereby monitoring the sewage discharge situation of the sewage pump main body 101 in real time. When the pressure drops to the set threshold, the staff is reminded to stop the machine and check in time.

[0035] Furthermore, the lifting assembly includes a liquid inlet pipe 109 arranged inside the support frame 104. The lower end of the liquid inlet pipe 109 is communicated with a storage spherical shell 110. A round rod 112 is fixedly installed inside the support frame 104. The round rod 112 penetrates through the upper end of the liquid inlet pipe 109, and the liquid inlet pipe 109 is movably connected with the round rod 112. A lifting rod 113 is welded on one side of the lower end of the liquid inlet pipe 109 close to the storage spherical shell 110. The upper end of the lifting rod 113 is fixedly connected with a traction rope 114. A guide wheel 115 is arranged on the outer side wall of the lower end of the sewage pump main body 101, and the guide wheel 115 corresponds to the storage spherical shell 110 one by one. The other end of the traction rope 114 bypasses the guide wheel 115 and is fixedly connected with the outer side wall of the lower end of the sewage pump main body 101. The liquid inlet pipe 109 is set to two and is symmetrically arranged. The lower end of the storage spherical shell 110 is communicated with a discharge valve 111. A fixed frame 116 is welded on one side of the lower end of the support frame 104 far from the filter cover 102, and the fixed frame 116 corresponds to the storage spherical shell 110 one by one. A first return spring 117 is fixedly installed inside the fixed frame 116, and the other end of the first return spring 117 is fixedly connected with the outer side wall of the storage spherical shell 110.

[0036] In this embodiment, during the downward movement of the first fixing ring 103, the towing rope 114 connected to the lifting rod 113 is gradually tightened. When the towing rope 114 is in a tightened state, at this time, the support frame 104 continues to move downward. At the same time, the towing rope 114 pulls the lifting rod 113, causing the storage spherical shell 110 to cooperate with the liquid inlet pipe 109 to rotate around the round rod 112. When the first fixing ring 103 moves into place, the towing rope 114 no longer pulls. At this time, the storage spherical shell 110 will rotate out of the inner cavity of the support frame 104 and turn to the lower part of the filter cover 102. At this time, the sewage pump main body 101 completes the deployment before use. Then, the sewage pump main body 101 is slowly placed into the waste water pool. At the same time, the waste water is poured into the storage spherical shell 110 through the liquid inlet pipe 109. The weight below the pump body is increased by the three storage spherical shells 110 filled with sewage. And because the weights of the three storage spherical shells 110 are all concentrated below the filter cover 102, the center of gravity height of the pump body is reduced during the operation of the sewage pump main body 101, thereby improving the anti-tipping performance of the pump body. And by forming an inclined angle between the support frame 104 and the storage spherical shell 110, the gravity of the water in the storage spherical shell 110 will generate a downward component force. This component force will be transmitted to the lower part of the support frame 104 through the inclined storage spherical shell 110, increasing the pressure of the rubber plate 105 on the support frame 104 on the ground, thereby enhancing the friction between the rubber plate 105 on the support frame 104 and the ground. The increase in friction helps to improve the stability of the support frame 104, enabling the entire support assembly to better resist external forces and prevent the sewage pump main body 101 from tilting, further reducing the situation of the filter cover 102 below the sewage pump main body 101 from tipping and blocking. And because an inclined angle is formed between the storage spherical shell 110 and the support frame 104, it is more convenient for sewage to be poured into the storage spherical shell 110 through the liquid inlet pipe 109, thereby improving the water storage efficiency of the storage spherical shell 110.

[0037] It should be noted that when the sewage pump main body 101 is working, the stability of the sewage pump main body 101 is increased by using the storage spherical shell 110 and the liquid inlet pipe 109 to store sewage. When carrying the sewage pump main body 101, the stored sewage can be discharged through the discharge valve 111, thereby reducing the carrying weight of the sewage pump main body 101, and thus making the sewage pump main body 101 more lightweight and convenient. Through the setting of the guide wheel 115, the towing direction of the towing rope 114 can be changed, so as to better tow and rotate the storage spherical shell 110. Through the setting of the first return spring 117, when the storage spherical shell 110 is lifted and rotated, at this time, the first return spring 117 is in a stretched state. Then, when the support frame 104 is retracted, the first return spring 117 will drive the storage spherical shell 110 to be received into the support frame 104, which is convenient for the upward movement and storage of the support frame 104 and the first fixing ring 103.

[0038] In use, first rotate the bidirectional lead screw 107 clockwise. The bidirectional lead screw 107 drives the first fixing ring 103 to move downward along the fixing rod 106 through the first lead screw sleeve 108. The first fixing ring 103 drives the support frame 104 to move accordingly, thereby unfolding the retracted support frame 104 so that the three support frames 104 support under the sewage pump main body 101. Since the three annularly distributed support frames 104 support under the sewage pump main body 101, even if the sewage pump main body 101 tilts, due to the support of the support frames 104, the contact area between the filter cover 102 on the sewage pump main body 101 and the sludge surface will be reduced, thereby reducing the blockage of the filter cover 102. At the same time, during the downward movement of the first fixing ring 103, the traction rope 114 connected to the lifting rod 113 gradually tightens. When the traction rope 114 is in a taut state, at this time, the support frame 104 continues to move downward. At the same time, the traction rope 114 pulls the lifting rod 113, causing the storage spherical shell 110 to cooperate with the liquid inlet pipe 109 to rotate around the round rod 112. When the first fixing ring 103 moves in place, the traction rope 114 no longer pulls, and at this time, the storage spherical shell 110 will rotate out of the inner cavity of the support frame 104 and rotate under the filter cover 102. At this time, the sewage pump main body 101 completes the unfolding before use. Then slowly place the sewage pump main body 101 into the waste water pool. At the same time, the waste water will be poured into the storage spherical shell 110 through the liquid inlet pipe 109. By filling three storage spherical shells 110, the weight under the pump body is increased. And because the weights of the three storage spherical shells 110 are concentrated under the filter cover 102, the center of gravity height of the pump body is reduced during the operation of the sewage pump main body 101, thereby improving the anti-tipping performance of the pump body. And by forming an inclined angle between the support frame 104 and the storage spherical shell 110, the gravity of the water in the storage spherical shell 110 will generate a downward component force. This component force will be transmitted to the lower part of the support frame 104 through the inclined storage spherical shell 110, increasing the pressure of the rubber plate 105 on the support frame 104 on the ground, thereby enhancing the friction between the rubber plate 105 on the support frame 104 and the ground. The increase in friction helps to improve the stability of the support frame 104, enabling the entire support assembly to better resist external forces and prevent the sewage pump main body 101 from tipping, further reducing the situation of tipping and blockage of the filter cover 102 under the sewage pump main body 101.

[0039] Example 2, refer to Figures 1 to 7, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an anti-clogging intelligent sewage pump for wastewater treatment, which solves the problem that the sewage attachments on the filter cover 102 are dried and affect the use of the sewage pump body 101 next time. The filter cover 102 cleaning component includes a second fixing ring 201 arranged above the first fixing ring 103, and a second screw rod sleeve 202 is arranged on the side of the second fixing ring 201 close to the bidirectional screw rod 107. A fixing frame 203 is arranged below the side of the second fixing ring 201 close to the bidirectional screw rod 107. The front and rear sides of the liquid outlet pipe 118 are welded with a limiting frame 204. The lower end of the fixing frame 203 passes through the middle of the limiting frame 204 and is fixedly connected with a protective tube 206, and the fixing frame 2 03 is movably connected with the limit frame 204, the protective cylinder 206 is arranged above the filter cover 102, the lower end of the inner wall of the protective cylinder 206 is bonded with a scraper ring 207, and the cross-section of the scraper ring 207 is wedge-shaped, the first fixing ring 103 and the second fixing ring 201 are symmetrically arranged, the size of the second screw rod sleeve 202 is adapted to the size of the bidirectional screw rod 107, and the second screw rod sleeve 202 is threadedly connected to the bidirectional screw rod 107, the front and rear sides of the lower end of the fixing frame 203 are both sleeved with a second return spring 205, the end of the second return spring 205 close to the limit frame 204 is fixedly connected to the limit frame 204, the size of the protective cylinder 206 is larger than the size of the filter cover 102, and the inner side of the scraper ring 207 fits with the outer wall of the filter cover 102.

[0040] In this embodiment, after the sewage pump is used, first rotate the bidirectional lead screw 107 counterclockwise. The bidirectional lead screw 107 cooperates with the first lead screw sleeve 108 to drive the first fixing ring 103 to move upward, thereby driving the support frame 104 and the storage spherical shell 110 to be retracted, thus reducing the occupied space of the sewage pump main body 101. At the same time, the bidirectional lead screw 107 cooperates with the second lead screw sleeve 202 to drive the second fixing ring 201 to move downward. After the first fixing ring 103 moves upward for a certain distance, at this time, the second fixing ring 201 contacts the fixing frame 203. Then continue to rotate the bidirectional lead screw 107, the first fixing ring 103 continues to move upward, and the second fixing ring 201 pushes the fixing frame 203 to move downward, while stretching the second return spring 205, so that the fixing frame 203 drives the protective cylinder 206 to move downward. At this time, the protective cylinder 206 moves downward from the upper end of the filter cover 102. At the same time, the scraping ring 207 inside the protective cylinder 206 will scrape and clean the sewage attachments remaining on the outer side of the filter cover 102 until the protective cylinder 206 covers the outer side of the filter cover 102. At this time, stop rotating the bidirectional lead screw 107. At the same time, the scraping ring 207 will drive the scraped attachments to move to the lower end of the filter cover 102 and separate from the filter cover 102, thus solving the problem that the sewage attachments on the filter cover 102 dry and solidify and affect the use of the sewage pump main body 101 next time. And because the protective cylinder 206 covers the outer side of the filter cover 102, it can protect the outer side of the filter cover 102, and cooperate with the retracted support frame 104 to cover the outer side of the protective cylinder 206, thereby forming a double-layer protection for the filter cover 102, and thus avoiding the situation that the filter cover 102 is knocked and deformed during transportation.

[0041] It should be noted that the cross-section of the scraping ring 207 is wedge-shaped, so that the scraping ring 207 can better scrape and clean the sewage attachments attached to the outer surface of the filter cover 102. Through the setting of the second return spring 205, when the bidirectional lead screw 107 rotates clockwise, the second fixing ring 201 separates from the fixing frame 203, and then relying on the spring resilience, the second return spring 205 drives the fixing frame 203 to move upward and reset, so that the protective cylinder 206 separates from the filter cover 102, and thus does not affect the sewage suction of the sewage pump main body 101.

[0042] The rest of the structure is the same as that of Embodiment 1.

[0043] When in use, after the sewage pump is used, the bidirectional screw rod 107 is first rotated counterclockwise, and the bidirectional screw rod 107 cooperates with the first screw rod sleeve 108 to drive the first fixing ring 103 to move upward, thereby driving the support frame 104 and the accumulation ball shell 110 to be retracted, thereby reducing the occupied space of the sewage pump body 101. At the same time, the bidirectional screw rod 107 cooperates with the second screw rod sleeve 202 to drive the second fixing ring 201 to move downward. After the first fixing ring 103 moves upward for a distance, the second fixing ring 201 contacts the fixing frame 203, and then the bidirectional screw rod 107 continues to be rotated, the first fixing ring 103 continues to move upward, and the second fixing ring 201 pushes the fixing frame 20 3 moves downward, and at the same time stretches the second return spring 205, so that the fixing frame 203 drives the protective cylinder 206 to move downward. At this time, the protective cylinder 206 moves downward from the upper end of the filter cover 102. At the same time, the scraper ring 207 inside the protective cylinder 206 will scrape and clean the sewage attachments remaining on the outside of the filter cover 102 until the protective cylinder 206 covers the outside of the filter cover 102. At this time, the two-way screw rod 107 is no longer rotated. At the same time, the scraper ring 207 will drive the scraped attachments to move to the lower end of the filter cover 102 and separate from the filter cover 102, thereby solving the problem that the sewage attachments on the filter cover 102 are dried and affect the next use of the sewage pump body 101.
