Description

Technical Field

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

[0002] Sewage pumps are widely used in municipal, environmental protection, sewage treatment, light industry, chemical industry, mining, petroleum, water conservancy, metallurgy and other industries to transport liquids containing solid particle suspensions or fibrous suspensions. They are major energy consumers and one of the key equipment in related industries.

[0003] According to the published patent CN218844718U, a blockage-resistant sewage pump is known, which includes a body and a filter device. A water pipe is provided on one side of the body, and the filter device is provided on one side of the body. The filter device includes a filter plate, and the filter plate is sleeved with the body. One side of the filter plate is fixedly connected to a motor, and the driving end of the motor passes through the filter plate and is fixedly connected to a brush. One side of the filter plate is fixedly connected to a fixed block.

[0004] During use, although the existing sewage pump has added a cleaning structure to the filter cover to reduce the blockage of the sewage pump during the suction process, in an environment with a lot of silt, the existing sewage pump lacks an effective anti-dumping support structure, and the pump body may tilt due to external forces (such as water flow impact). The tilted pump body causes the contact area between the filter cover and the silt to increase, and the silt accumulates on the inclined surface due to gravity, forming a "mud cake" layer, which in turn causes the filter mesh pores at the inclined position to be completely blocked, which not only increases the operating resistance of the sewage pump, but also significantly increases energy consumption. In addition, the tilt of the pump body may also affect the stability and service life of the sewage pump, and increase the frequency of maintenance and replacement. Summary of the Invention

[0005] In view of the above or prior art, in an environment with a lot of silt, the existing sewage pump lacks an effective anti-dumping support structure, and the pump body may tilt due to external forces (such as water flow impact). The tilted pump body causes the contact area between the filter cover and the silt to increase, and the silt accumulates on the inclined surface due to gravity, forming a "mud cake" layer, which in turn causes the filter mesh pores at the inclined position to be completely blocked, which not only increases the operating resistance of the sewage pump, but also significantly increases energy consumption.

[0011] As a preferred solution of the anti-clogging intelligent sewage pump for wastewater treatment of the present invention, wherein: the liquid inlet pipes are provided in two, and the liquid inlet pipes are symmetrically arranged, the lower end of the accumulation spherical shell is connected to the discharge valve, the lower end of the support frame is welded with a fixing frame on the side away from the filter cover, and the fixing frame corresponds to the accumulation spherical shell one-to-one, and a first return spring is fixedly installed on the inner side of the fixing frame, and the other end of the first return spring is fixedly connected to the outer side wall of the accumulation spherical shell.

[0012] As a preferred solution of the anti-clogging intelligent sewage pump for wastewater treatment of the present invention, the filter cover cleaning assembly includes a second fixing ring arranged above the first fixing ring, a second screw sleeve is provided on the side of the second fixing ring close to the bidirectional screw, a fixing frame is provided below the side of the second fixing ring close to the bidirectional screw, and a limiting frame is welded on the front and rear sides of the liquid outlet pipe. The lower end of the fixing frame passes through the middle of the limiting frame and is fixedly connected to a protective cylinder, and the fixing frame is movably connected to the limiting frame. The protective cylinder is arranged above the filter cover, and a scraper ring is bonded to the lower end of the inner wall of the protective cylinder, and the cross-section of the scraper ring is wedge-shaped.

[0013] As a preferred solution of the anti-clogging intelligent sewage pump for wastewater treatment of the present invention, the first fixing ring and the second fixing ring are symmetrically arranged, the size of the second screw sleeve is adapted to the size of the bidirectional screw, and the second screw sleeve is threadedly connected to the bidirectional screw, and the front and rear sides of the lower end of the fixing frame are both sleeved with a second return spring, and 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 scraper 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 are as follows: the present invention can unfold the folded support frame so that the three support frames are supported below the sewage pump body. Since the three annular support frames are supported below the sewage pump body, even if the sewage pump body falls over, the support of the support frame will reduce the contact area between the filter cover on the sewage pump body and the inclined silt surface, thereby reducing the clogging of the filter cover.

[0015] The weight below the pump body can also be increased by using three storage spheres filled with sewage, and since the weight of the three storage spheres is gathered under the filter cover, the center of gravity height of the pump body is lowered during the operation of the sewage pump body, thereby improving the anti-dumping performance of the pump body, and by forming an inclined angle between the support frame and the storage sphere, the gravity of the water in the storage sphere will generate a downward component force, and this component force will be transmitted to the bottom of the support frame through the inclined storage sphere, 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, so that the entire support assembly can better resist external forces, prevent the sewage pump body from tipping over, and further reduce the possibility of tipping and blockage of the filter cover under the sewage pump body.

[0016] The fixing 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 scraper ring on the inside of 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 two-way screw rod will no longer rotate. At the same time, the scraper 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 of the sewage attachments on the filter cover drying up and affecting the next use of the sewage pump body.

[0017] The protective tube covers the outside of the filter cover, thereby protecting the outside of the filter cover, and the retracted support frame covers the outside of the protective tube, thereby forming a double layer of protection for the filter cover, thereby avoiding the filter cover from being bumped and deformed during transportation.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0030] Example 1, reference Figures 1 to 6, which is the first embodiment of the present invention, which provides an anti-clogging intelligent sewage pump for wastewater treatment, which can lower the center of gravity height of the pump body during operation of the pump body, thereby improving the anti-dumping performance of the pump body, and further reducing the occurrence of dumping and clogging of the filter cover 102 below the pump body. It includes an anti-dumping mechanism 100, which includes a sewage pump body 101, and also includes a filter cover 102 arranged below the sewage pump body 101 for filtering impurities, a first fixing ring 103 is arranged on the outside of the sewage pump body 101, the first fixing ring 103 is provided with a support assembly for anti-dumping support of the sewage pump body 101, and an accumulation ball shell 110 arranged below the first fixing ring, a lifting assembly for lifting the accumulation ball shell 110 is arranged on the inner side of the support assembly, and a cleaning mechanism 200 is provided on one side of the first fixing ring 103, the cleaning mechanism 200 includes a filter cover cleaning assembly arranged on the outside of the filter cover 102 for cleaning residual attachments on the surface of the filter cover 102.

[0031] In this embodiment, by controlling the first fixing ring 103 to move downward, the support assembly on the first fixing ring 103 supports the bottom of the sewage pump body 101, and a triangular stable structure is formed by three inclined support frames 104 to support the bottom of the sewage pump body 101. At the same time, when the support assembly moves down to its place, the pulling assembly inside the support assembly will pull the accumulation ball shell 110, so that the accumulation ball shell 110 is rotated out of the inner cavity of the support assembly, and the accumulation ball shell 110 is rotated to the bottom of the filter cover 102, and then the sewage is poured into the accumulation ball shell 110. 10, the weight below the pump body is increased by three storage spheres 110 filled with sewage, thereby lowering the center of gravity of the pump body during the operation of the sewage pump main body 101, thereby improving the anti-dumping performance of the pump body, and forming an inclined angle between the support frame 104 and the storage sphere 110. The gravity of the water in the storage sphere 110 will generate a downward component force, and this component force will be transmitted to the bottom of the support frame 104 through the inclined storage sphere 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, so that the entire support anti-dumping assembly can better resist external forces, prevent the pump body from tilting, and further reduce the situation of the filter cover 102 under the pump body tipping and clogging. When the sewage pump main body 101 is used, the first fixing ring 103 is controlled to move upward, so that the support assembly and the accumulation ball shell 110 are retracted, 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 can scrape and clean the sewage attachments remaining on the filter cover 102, avoiding the drying of the sewage attachments and affecting the next use of the sewage pump main body 101. After the filter cover cleaning assembly is cleaned, the filter cover cleaning assembly will cover the outside of the filter cover 102, thereby protecting the outside of the filter cover 102, and at the same time cooperate with the retracted support assembly to cover the outside of the filter cover cleaning assembly, thereby forming a double layer of protection for the filter cover 102, avoiding the filter cover 102 from being bumped and deformed during transportation.

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

[0033] In this embodiment, the first screw rod 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 screw rod 107 clockwise, and the bidirectional screw rod 107 drives the first fixing ring 103 to move downward along the fixing rod 106 through the first screw rod sleeve 108, and the first fixing ring 103 drives the support frame 104 to follow the movement, and then unfolds the retracted support frame 104, so that the three support frames 104 are supported under the sewage pump body 101. Since the three annular support frames 104 are supported under the sewage pump body 101, even if the sewage pump body 101 falls over, the support of the support frame 104 will reduce the contact area between the filter cover 102 on the sewage pump body 101 and the inclined silt surface, thereby reducing the clogging of the filter cover 102.

[0034] It is worth noting that since there are three support frames 104 and they are distributed in a ring on the outside of the sewage pump body 101, a triangular stable structure is formed to support the bottom of the sewage pump body 101, reducing the risk of tipping over of the sewage pump body 101, and the side surfaces of the support frames 104 are also designed to be inclined, ensuring that the support frames 104 and the sewage pump body 101 also form an inclined angle, thereby ensuring the support stability of each support frame 104 on the sewage pump body 101, and due to the setting of the rubber plate 105 on the support frame 104, the contact area and friction between the support frame 104 and the ground can be further increased, thereby improving the anti-tip effect of the sewage pump body 101, and a pressure sensor is provided in the inner cavity of the liquid outlet pipe 118, and the pressure condition inside the liquid outlet pipe 118 is monitored by the pressure sensor. The pressure sensor transmits the signal to the control system, thereby monitoring the sewage discharge condition of the sewage pump body 101 in real time. When the pressure drops to the set threshold, the staff is reminded to stop the machine for inspection in time.

[0035] Furthermore, the lifting assembly includes a liquid inlet pipe 109 arranged on the inner side of the support frame 104, the lower end of the liquid inlet pipe 109 is connected to the accumulation ball shell 110, and a round rod 112 is fixedly installed on the inner side of the support frame 104. The round rod 112 passes through the upper end of the liquid inlet pipe 109, and the liquid inlet pipe 109 is movably connected to the round rod 112. A lifting rod 113 is welded to the side of the lower end of the liquid inlet pipe 109 close to the accumulation ball shell 110, and the upper end of the lifting rod 113 is fixedly connected to a traction rope 114. A guide wheel 115 is provided on the outer side wall of the lower end of the sewage pump body 101, and the guide wheel 115 is connected to the accumulation ball shell. 110 correspond one to one, the other end of the traction rope 114 passes around the guide wheel 115 and is fixedly connected to the outer side wall of the lower end of the sewage pump body 101, two liquid inlet pipes 109 are set, and the liquid inlet pipes 109 are symmetrically arranged, the lower end of the accumulation ball shell 110 is connected to the discharge valve 111, and a fixing frame 116 is welded on the side of the lower end of the support frame 104 away from the filter cover 102, and the fixing frame 116 corresponds one to one to the accumulation ball shell 110, and a first return spring 117 is fixedly installed on the inner side of the fixing frame 116, and the other end of the first return spring 117 is fixedly connected to the outer side wall of the accumulation ball shell 110.

[0036] In this embodiment, during the downward movement of the first fixing ring 103, the traction rope 114 connected to the lifting rod 113 is gradually tightened. When the traction rope 114 is in a tightened state, the support frame 104 continues to move downward. At the same time, the traction rope 114 pulls the lifting rod 113, so that the accumulation ball shell 110 cooperates with the liquid inlet pipe 109 to rotate around the round rod 112. When the first fixing ring 103 moves into place, the traction rope 114 is no longer pulled. At this time, the accumulation ball shell 110 will be rotated out of the inner cavity of the support frame 104 and rotated to the bottom of the filter cover 102. At this time, the sewage pump body 101 completes the expansion before use, and then the sewage pump body 101 is slowly placed into the wastewater pool. At the same time, the wastewater will be poured into the liquid inlet pipe 109. The sewage pump body 101 is provided with a plurality of accumulating spherical shells 110, and the weight of the three accumulating spherical shells 110 is increased by the three accumulating spherical shells 110 filled with sewage, and the weight of the three accumulating spherical shells 110 is gathered under the filter cover 102, thereby lowering the center of gravity of the pump body during the operation of the sewage pump body 101, thereby improving the anti-dumping performance of the pump body, and forming an inclined angle between the support frame 104 and the accumulating spherical shell 110. The gravity of the water in the accumulating spherical shell 110 will generate a downward component force, and this component force will be transmitted to the bottom of the support frame 104 through the inclined accumulating spherical shell 110, thereby 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, so that the entire support assembly can better resist external forces, prevent the sewage pump body 101 from tilting, and further reduce the possibility of the filter cover 102 below the sewage pump body 101 tipping over and clogging. Moreover, since the accumulation spherical shell 110 and the support frame 104 form an inclined angle, it is more convenient for sewage to be poured into the accumulation spherical shell 110 from the liquid inlet pipe 109, thereby improving the water storage efficiency of the accumulation spherical shell 110.

[0037] It is worth noting that when the sewage pump body 101 is working, the sewage is accumulated by using the accumulation ball shell 110 and the liquid inlet pipe 109 to increase the stability of the sewage pump body 101. When the sewage pump body 101 is carried, the accumulated sewage can be discharged through the discharge valve 111, thereby reducing the carrying weight of the sewage pump body 101, and making the sewage pump body 101 more lightweight and convenient. By setting the guide wheel 115, the traction direction of the traction rope 114 can be changed, so as to better pull and rotate the accumulation ball shell 110. By setting the first return spring 117, when the accumulation ball shell 110 is lifted and rotated, the first return spring 117 is in a stretched state, which makes it convenient to retract the support frame 104 during the folding process. The first return spring 117 will drive the accumulation ball shell 110 into the support frame 104, thereby facilitating the upward movement and storage of the support frame 104 and the first fixing ring 103.

[0038] When in use, first rotate the bidirectional screw rod 107 clockwise, and the bidirectional screw rod 107 drives the first fixing ring 103 to move downward along the fixing rod 106 through the first screw rod sleeve 108, and the first fixing ring 103 drives the support frame 104 to follow the movement, and then the retracted support frame 104 is unfolded, so that the three support frames 104 are supported under the sewage pump body 101. Since the three annular support frames 104 are supported under the sewage pump body 101, even if the sewage pump body 101 falls over, the support frames 104 can be used to support the bottom of the sewage pump body 101. The support of the support frame 104 will also reduce the contact area between the filter cover 102 on the sewage pump body 101 and the inclined silt surface, thereby reducing the clogging 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 is gradually tightened. When the traction rope 114 is in a tightened state, the support frame 104 continues to move downward. At the same time, the traction rope 114 pulls the lifting rod 113, causing the accumulation ball shell 110 to rotate around the round rod 112 in conjunction with the liquid inlet pipe 109. When the first fixing ring 103 moves into place, the traction rope 114 is no longer pulled, and the accumulating ball shell 110 will be rotated out of the inner cavity of the support frame 104 and rotated to the bottom of the filter cover 102. At this time, the sewage pump body 101 completes the unfolding before use, and then the sewage pump body 101 is slowly placed in the wastewater pool. At the same time, the wastewater will be poured into the accumulating ball shell 110 through the liquid inlet pipe 109, and the weight of the bottom of the pump body will be increased by the three full accumulating ball shells 110. And because the weight of the three accumulating ball shells 110 is gathered on the filter cover 10 2, thereby achieving the goal of lowering the center of gravity height of the pump body during operation of the sewage pump body 101, thereby improving the anti-dumping performance of the pump body, and through the support frame 104 and the accumulation ball shell 110 forming an inclined angle, the gravity of the water in the accumulation ball shell 110 will generate a downward component force, which will be transmitted to the bottom of the support frame 104 through the inclined accumulation ball 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, prevent the sewage pump body 101 from tipping over, and further reduce the risk of the filter cover 102 below the sewage pump body 101 tipping over and clogging.

[0039] Example 2, reference 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 assembly 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 to a protective cylinder 206, and the fixing frame 2 03 is movably connected to 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, and 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 the outer wall of the filter cover 102.

[0040] In this embodiment, after the sewage pump is used, the two-way screw rod 107 is rotated counterclockwise first, and the two-way 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 two-way 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 two-way screw rod 107 is continued to be rotated. The first fixing ring 103 continues to move upward, and the second fixing ring 201 pushes the fixing frame 203 to move downward. At the same time, the second return spring 205 is stretched, so that the fixing frame 203 drives the protective cylinder 206 to move downward. At this time, the protective cylinder 206 is removed from the filter cover 10 2 moves downward, and at the same time, the scraper ring 207 on the inner side of 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 will no longer rotate, and 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, and because the protective cylinder 206 covers the outside of the filter cover 102, it can protect the outside of the filter cover 102, and cooperate with the retracted support frame 104 to cover the outside of the protective cylinder 206, thereby forming a double-layer protection for the filter cover 102, thereby avoiding the filter cover 102 from being bumped and deformed during transportation.

[0041] It is worth noting that the cross-section of the scraper ring 207 is wedge-shaped, so that the scraper 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 reset spring 205, when the bidirectional screw 107 rotates clockwise, the second fixed ring 201 is separated from the fixed frame 203, and then with the help of the spring resilience, the second reset spring 205 drives the fixed frame 203 to move upward and reset, thereby separating the protective cylinder 206 from the filter cover 102, and thus will not affect the sewage suction of the sewage pump body 101.

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

[0043] When in use, after the sewage pump is used, the two-way screw rod 107 is rotated counterclockwise first, and the two-way 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 two-way 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 two-way screw rod 107 is continued 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 scrapes and cleans 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 drives 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.
