Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a sewage pumping station and a construction method thereof. Background Art

[0002] Urban sewage treatment is an important part of environmental protection and environmental friendliness. Sewage pumping stations are equipment used to transport sewage, which can transport sewage to sewage treatment sites through suction.

[0003] At present, sewage is usually directly input into a sewage pumping station, and the suction effect of the sewage pumping station is used to transport the sewage, and the sewage is directly transported to a sewage treatment site.

[0004] However, since sewage contains impurities of varying volumes, there is a problem that the impurities in the sewage enter the pump body and cause blockage inside the pump body; at the same time, due to the presence of impurities in the sewage, when the pump body is placed in the sewage, the impurities will adhere to the pump body, which can easily pose a potential threat to the normal operation of the pump body and reduce the reliability of the pump body.

[0005] With respect to the above-mentioned related technologies, the inventor believes that there is a defect that the pump body of the sewage pumping station is easily affected by impurities and its reliability. Summary of the invention

[0006] In order to reduce the impact of impurities in sewage on the reliability of a sewage pump station pump body, the present application provides a sewage pump station and a construction method thereof.

[0007] In the first aspect, the sewage pump station provided in this application adopts the following technical solution: A sewage pump station comprises: a shell, wherein the shell is provided with an input pipeline and an output pipeline; a filtering device, which is arranged in the shell, wherein the input pipeline is arranged on a side of the shell close to the filtering device; a pump assembly, which is arranged in the shell, wherein the pump assembly and the filtering device are arranged at two ends inside the shell, and the output pipeline is arranged on a side of the shell close to the pump assembly. The pump assembly comprises a pump body, a floating member, a driving mechanism and a cleaning mechanism, wherein a fixed end of the driving mechanism is connected to the shell, a movable end of the driving mechanism is connected to the pump body, the driving mechanism drives the pump body to move in the shell, the floating member is connected to the lower side of the pump body, a limiting part is arranged at the bottom of the shell, the floating member cooperates with the limiting part, a cleaning mechanism is arranged on the top of the shell, the cleaning mechanism is arranged on one side of the pump body, the cleaning mechanism is used to accelerate the flow speed of sewage in the shell so that the sewage cleans the pump body, and the output end of the pump body is connected to the output pipeline.

[0008] By adopting the above technical scheme, the shell serves as the bearing structure of the sewage pump station, so that the sewage pump station can be moved as a whole and pre-installed before being placed in the placement tank. Compared with installation in the placement tank, it helps to reduce the difficulty of installation, reduce the installation time in the placement tank, and improve efficiency; the two ends of the shell are respectively provided with a filtering device and a pump group device. By setting the filtering device at the end close to the input pipeline, the sewage can be filtered first after entering the shell, reducing the risk of impurities carried in the sewage entering the pump body, improving the cleanliness of the pump body, and ensuring the reliability of the pump body operation; the pump group device is set at the end of the shell close to the output pipeline, which is used to transport the sewage entering the shell to the output pipeline and then discharge it to the sewage treatment site. The pump body is driven by a driving mechanism to realize The movement in the shell, since the float part is connected to the lower side of the pump body, on the one hand, it helps to make the pump body float smoothly when the pump body needs to be repaired, thereby reducing the driving pressure of the driving mechanism; on the other hand, the float part can avoid a violent collision between the pump body and the bottom of the shell when the pump body is placed in the shell, thereby affecting the reliability of the pump body. At the same time, since a limiting part is provided at the bottom of the shell, the float part can be limited by the limiting part, thereby realizing the limiting effect on the pump body, which helps to stably place the pump body at the bottom of the shell, and transport the sewage in the shell to the output pipeline through the suction of the pump body; a cleaning mechanism is provided on one side of the pump body, so that when the pump body is repaired, the outside of the pump body can be cleaned through the cleaning mechanism to avoid external adhesion of impurities and affect the normal operation of the pump body, thereby improving the reliability of the pump body.

[0009] Optionally, the pump assembly device also includes a filter layer, which is connected to the inner wall of the shell, parallel to the bottom of the shell, and arranged longitudinally between the top and the bottom of the shell. The filter layer is provided with an avoidance hole, which cooperates with the float, and the cleaning mechanism is arranged above the filter layer.

[0010] By adopting the above technical scheme, the filter layer is used to further filter the position where the pump body is located, so that there is a filtering effect between the upper layer and the lower layer of the shell at one end where the pump group device is provided, so that the cleanliness of the upper layer of the shell is higher than the cleanliness of the lower layer, and by arranging an avoidance hole in the filter layer, the pump body and the floating body can pass through the avoidance hole and move from the lower layer of the shell to the upper layer, and the water flow speed of the upper layer with higher cleanliness is accelerated by the cleaning mechanism arranged on the upper layer, and the pump body is cleaned by accelerating the flowing water flow, thereby improving the cleanliness of the outside of the pump body, which not only helps to ensure the reliable operation of the pump body, but also facilitates the inspection and maintenance of the pump body.

[0011] Optionally, the filtering device includes a first filtering mechanism, which includes a filter basket and a first lifting assembly, the fixed end of the first lifting assembly is arranged at the top of the shell, the movable end of the first lifting assembly is connected to the filter basket, the first lifting assembly is used to drive the filter basket to move, and the input pipeline is arranged above the top of the filter basket when it is in the lowest position.

[0012] By adopting the above technical solution, the input pipeline transports the sewage into the shell, and allows the sewage to enter the filter basket, and the first filtering action is performed through the filter basket, so that some impurities in the sewage are retained in the filter basket, thereby improving the cleanliness of the sewage flowing out of the filter basket and reducing the impact of impurities on the pump body; because the filter basket is connected to the first lifting assembly, the filter basket can be lifted to the top of the shell after filtering the sewage, which can facilitate the inspection of the filter basket on the one hand, and the cleaning of impurities in the filter basket on the other hand, so as to ensure that the filtering effect of the filter basket is reliably achieved.

[0013] Optionally, a clearing component is provided on the inner side of the top of the shell, and the clearing component includes a connecting piece, a first clearing piece and a water spray piece. One side of the connecting piece is connected to the shell, and the other side of the connecting piece is provided with a plurality of first clearing pieces. The bottom and side walls of the filter basket are provided with first filter holes. The first clearing piece corresponds to the first filter hole at the bottom of the filter basket. The diameter of the first clearing piece is smaller than the diameter of the first filter hole. A plurality of water spray pieces are provided, and the plurality of water spray pieces are distributed in the shell. The water spray pieces are used to flush the filter basket.

[0014] By adopting the above technical solution, since the bottom of the filter basket is mainly used to carry impurities in sewage, there is a greater risk that the first filter hole will be blocked by impurities. The first clearing member arranged on the connecting member can correspond to the first filter hole at the bottom of the filter basket, and the diameter of the first clearing member is smaller than the diameter of the first filter hole. Because the first clearing member can clear the first filter hole, the impurities in the first filter hole at the bottom of the filter basket can be poked out, and combined with the flushing effect of the water spray member on the filter basket, the first filter hole of the filter basket can be further cleared to ensure that the filter basket can perform the filtering function normally.

[0015] Optionally, a flipping piece is provided in the shell, and two first lifting assemblies are provided. The two first lifting assemblies are respectively rotated to connect the connection points of the two opposite first side surfaces of the filter basket, and the flipping piece cooperates with the second side surface of the filter basket to flip the filter basket around the straight line where the two connection points are located.

[0016] By adopting the above technical solution, when the filter basket is lifted by the first lifting assembly, the flipping member will stop the end face of the second side of the filter basket, thereby causing a height difference between the two ends of the filter basket. Since the first lifting assembly is rotatably connected to the connection between the filter basket, the filter basket can be flipped around the straight line where the two connections are located. Therefore, when a large height difference occurs at both ends of the filter basket, the filter basket will flip toward the flipping member, thereby turning the filter basket upside down. On the one hand, it helps to clean the bottom of the filter basket, and on the other hand, it can pour out impurities in the filter basket, thereby improving the cleaning efficiency.

[0017] Optionally, the filter device also includes a second filter mechanism, the second filter mechanism includes a baffle, the baffle is vertically arranged between the first filter mechanism and the pump group device, the flip member is arranged on the side of the shell away from the baffle, and the side of the baffle close to the filter basket is provided with a pushing component, and the pushing component is used to push the filter basket to flip.

[0018] By adopting the above technical solution, the filter basket can be flipped with the assistance of the pushing component, thereby avoiding the problem that the filter basket cannot be reliably flipped due to insufficient height difference between the two ends of the filter basket caused by the flipping member.

[0019] Optionally, the pushing assembly includes a first pushing member and a second pushing member, and along the vertical direction, the first pushing member and the second pushing member are respectively arranged above and below the flip member.

[0020] By adopting the above technical solution, since the height positions of the first pushing member and the second pushing member are different, it is convenient to more conveniently realize the inversion and resetting of the filter basket by the difference in the pushing position of the filter basket, thereby ensuring the reliability of the filter basket flipping.

[0021] Optionally, the first filtering mechanism also includes a collecting box body and a second lifting assembly, the collecting box body is sleeved on the outside of the filter basket, the top of the collecting box body is provided with a first opening, the side of the collecting box body close to the baffle is provided with a second opening, the bottom inner side of the collecting box body is inclined, the thickness of the bottom of the collecting box body close to the baffle end is greater than the thickness of the bottom of the collecting box body away from the baffle end, the fixed end of the second lifting assembly is fixed to the top of the shell, and the movable end of the second lifting assembly is connected to the collecting box body.

[0022] By adopting the above technical solution, the first opening of the collecting box body is used to place the filter basket in the collecting box body, so as to collect the impurities deposited after being filtered out by the filter basket and the impurities poured out after the filter basket is turned over through the collecting box body, thereby cleaning the impurities around the filter basket and improving the cleanliness; the second pulling assembly is used to pull the collecting box body upwards to clean the impurities in the collecting box body; since the flow direction of the sewage is from the first filter mechanism to the second filter mechanism, there will be a problem of impurities accumulating at the baffle, and the collecting box body is provided with a second opening, through which the bottom of the collecting box body can scrape the baffle, thereby cleaning the impurities at the baffle and reducing the blockage problem.

[0023] Optionally, the second filtering mechanism includes a filter plate, a second clearing member and a third lifting assembly, the filter plate is arranged at an angle, the first end of the filter plate close to the pump group device is higher than the second end of the filter plate close to the baffle, the second clearing member is arranged at the second end of the filter plate, a second filter hole is opened on the baffle, the second clearing member cooperates with the second filter hole, the fixed end of the third lifting assembly is arranged at the top of the shell, the movable end of the third lifting assembly is connected to the filter plate, and the second clearing member is used to clear the second filter hole when the filter plate moves.

[0024] By adopting the above technical scheme, the sewage output from the filter basket can be filtered twice through the baffle, so that larger impurities are retained on the side of the baffle close to the filter basket and cleaned to the outside of the shell through the collection box; the sewage is filtered for the third time on the filter plate, and because the filter plate is inclined, the impurities can be retained above the filter plate, and the sewage can flow to the bottom of the filter plate to separate the sewage from the impurities; when cleaning the impurities on the filter plate, the filter plate is driven up by the third lifting assembly, so that the second dredging member provided at the second end of the filter plate can dredge the second filter hole on the baffle, thereby improving the cleanliness of the baffle and enabling the baffle to reliably achieve the filtering effect.

[0025] In the second aspect, the construction method of the sewage pump station provided in this application adopts the following technical solution: A construction method for a sewage pumping station is applied to the above-mentioned sewage pumping station, and the construction method of the sewage pumping station includes: pre-installation of a pump assembly device, after pre-assembling the pump body with the float and the driving mechanism respectively, assembling and connecting the driving mechanism and the cleaning mechanism in the shell; digging a placement groove, placing the shell as a whole in the placement groove; installation of a filter device, according to the volume of the placement groove and the shell, selectively installing the filter device in the shell.

[0026] By adopting the above technical scheme, the pump unit can be pre-installed in advance, and after the installation is completed, the pump unit can be moved to the placement tank by moving the shell as a whole; because the filter device and the pump unit are relatively independent structures, it is possible to selectively determine whether to install the filter device in the shell according to the size of the placement tank and the size of the shell, thereby improving the applicability to different placement tanks, so that the sewage pumping station can realize sewage treatment in placement tanks of different sizes, and will not affect the normal sewage transportation function of the pump unit.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. The shell serves as the bearing structure of the sewage pump station, so that the sewage pump station can be moved as a whole and pre-installed before being placed in the placement tank. Compared with installation in the placement tank, it helps to reduce the difficulty of installation, reduce the installation time in the placement tank, and improve efficiency; filtering devices and pump group devices are respectively arranged at both ends of the shell. By arranging the filtering device at the end close to the input pipeline, the sewage can be filtered first after entering the shell, reducing the risk of impurities carried in the sewage entering the pump body, improving the cleanliness of the pump body, and ensuring the reliability of the pump body operation; a pump group device is arranged at the end close to the output pipeline in the shell, which is used to transport the sewage entering the shell to the output pipeline and then discharge it to the sewage treatment site. The pump body is realized in the shell through the driving mechanism. Since the floating body is connected to the lower side of the pump body, on the one hand, it is helpful to make the pump body float smoothly when the pump body needs to be repaired, thereby reducing the driving pressure of the driving mechanism. On the other hand, the floating body can prevent the pump body from violently colliding with the bottom of the shell when the pump body is placed in the shell, thereby affecting the reliability of the pump body. At the same time, since a limiting part is provided at the bottom of the shell, the floating body can be limited by the limiting part, thereby realizing the limiting effect on the pump body, which helps to stably place the pump body at the bottom of the shell, and transport the sewage in the shell to the output pipeline through the pump body; a cleaning mechanism is provided on one side of the pump body, so that when the pump body is repaired, the outside of the pump body can be cleaned through the cleaning mechanism to avoid external impurities adhering to the outside and affecting the normal operation of the pump body, thereby improving the reliability of the pump body; 2. The filter layer is used to further filter the location of the pump body, so that there is a filtering effect between the upper layer and the lower layer of the end of the shell where the pump group device is provided, so that the cleanliness of the upper layer of the shell is higher than that of the lower layer, and by providing an avoidance hole in the filter layer, the pump body and the floating body can pass through the avoidance hole and move from the lower layer of the shell to the upper layer, and the water flow speed of the upper layer with higher cleanliness is accelerated by the cleaning mechanism provided on the upper layer, and the pump body is cleaned by accelerating the flowing water flow, thereby improving the cleanliness of the outside of the pump body, which not only helps to ensure the reliable operation of the pump body, but also facilitates the maintenance of the pump body; 3. The pump unit can be pre-installed in advance, and after the installation is completed, the pump unit can be moved to the placement tank by moving the shell as a whole; because the filter device and the pump unit are relatively independent structures, it is possible to selectively determine whether to install the filter device in the shell according to the size of the placement tank and the size of the shell, thereby improving the applicability to different placement tanks, so that the sewage pumping station can realize sewage treatment in placement tanks of different sizes, and will not affect the normal sewage transportation function of the pump unit.

[0037] The following is combined with Figure 1-Figure 8 The present application is further described in detail. In this embodiment, if not clearly specified, "connected", "connected" and "fixed" are understood in a broad sense, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection and interaction between two elements, etc., which can be understood according to the specific circumstances. In the absence of any contrary explanation, the directional words used in this application, such as "inside" and "outside", refer to the outline of the corresponding parts themselves.

[0038] like Figure 1-Figure 3 As shown, in the first aspect, an embodiment of the present application discloses a sewage pumping station, which includes a shell 1, a filtering device and a pump group device 3. The sewage pumping station is used to pump and transport sewage so that the sewage can be transported to a sewage treatment site for sewage treatment.

[0039] The shell 1 is provided with an input pipe 11 and an output pipe 12. Sewage enters the shell 1 through the input pipe 11, and is transported to the output pipe 12 by the pumping action in the shell 1, and is discharged to the sewage treatment site through the output pipe 12. The setting positions of the input pipe 11 and the output pipe 12 are set as required, so that there can be a height difference between the input pipe 11 and the output pipe 12, so that the sewage can be sucked from a low place to a high place. The shell 1 serves as the bearing structure of the sewage pump station, so that the sewage pump station can be moved as a whole, and the internal structure of the shell 1 can be pre-installed before the sewage pump station is installed in the placement tank. Compared with installation in the placement tank, this installation method helps to reduce the difficulty of installation, reduce the installation time in the placement tank, and improve assembly efficiency. During use, the internal structure of the shell 1 can be pre-installed for use. When the sewage pumping station needs to be activated, the installed sewage pumping station is directly placed in the placement tank, and the input pipe 11 and the output pipe 12 are respectively connected to the connecting structure of the sewage and the sewage treatment site, so that the assembly of the sewage pumping station can be conveniently realized, which is simple and efficient.

[0040] like Figure 1-Figure 3As shown, an inspection platform 17 is provided outside the housing 1 for operators to stand on, providing a reliable standing point for operators. A slide groove is provided on the inspection platform 17, and a sliding block is slidably connected in the slide groove. The sliding block is rotatably connected to the climbing ladder 16, so that the climbing ladder 16 can be set on one side of the inspection platform 17, which is convenient for inspection when the top of the housing 1 is higher; when the top of the housing 1 is lower and does not need to be climbed, the climbing ladder 16 can be moved and placed on the top of the housing 1 by the sliding block for use.

[0041] like Figure 1-Figure 3 As shown, the filter device is arranged in the housing 1, and the input pipeline 11 is arranged on the side of the housing 1 close to the filter device. By arranging the filter device at one end close to the input pipeline 11, the sewage can be filtered first after entering the housing 1, reducing the risk of impurities carried in the sewage entering the pump unit 3, improving the cleanliness of the pump unit 3, and ensuring the reliability of the operation of the pump unit 3.

[0042] The pump assembly 3 is arranged in the shell 1, and the pump assembly 3 and the filtering device are arranged at two ends inside the shell 1. The output pipeline 12 is arranged on one side of the shell 1 close to the pump assembly 3, so that sewage can enter the shell 1 through the input pipeline 11, be filtered by the filtering device and sucked by the pump assembly 3, and then be transported to the sewage treatment site through the output pipeline 12.

[0043] like Figure 1-Figure 3As shown, the pump assembly 3 includes a pump body 31, a float 32, a drive mechanism 33 and a cleaning mechanism 34. The fixed end of the drive mechanism 33 is connected to the housing 1, and the movable end of the drive mechanism 33 is connected to the pump body 31, so that the pump body 31 is driven by the drive mechanism 33 to move vertically up and down in the housing 1, so as to facilitate the sinking installation and floating maintenance of the pump body 31 in the housing 1. The float 32 is connected to the lower side of the pump body 31, and a limiter 13 is provided at the bottom of the housing 1, and the float 32 cooperates with the limiter 13. Since the float 32 is connected to the lower side of the pump body 31, on the one hand, it is helpful to make the pump body 31 float smoothly for maintenance when there is sewage in the housing 1, and reduce the driving force required for the drive mechanism 33 to drive the pump body 31 to move; on the other hand, the float 32 can prevent the pump body 31 from violently colliding with the bottom of the housing 1 when the pump body 31 is placed in the housing 1, which affects the reliability of the pump body 31. At the same time, since the bottom of the shell 1 is provided with a limiting portion 13, the floating member 32 can be limited by the limiting portion 13, thereby achieving a limiting effect on the pump body 31, which helps to stably place the pump body 31 at the bottom of the shell 1 to transport the sewage to the output pipeline 12. In this embodiment, the floating member 32 can be an inflatable airbag, or other structures that can achieve floating and buffering effects. The diameter of the floating member 32 is not less than the diameter of the pump body 31. On the one hand, it ensures the stability of the pump body 31 in the shell 1; on the other hand, the floating member 32 can reduce the risk of circumferential collision of the pump body 31. The limiting portion 13 can be a plate-shaped, groove-shaped, block-shaped or other shaped structure provided at the bottom of the shell 1, which can achieve a horizontal limiting effect on the floating member 32. The pump body 31 is connected to the output pipeline 12 through a connecting pipeline. When the pump body 31 needs to be repaired, the connecting pipeline can be removed or moved to facilitate the disassembly, lifting and maintenance of the pump body 31; the connecting pipeline can be fixed to the inner wall of the shell 1 or other appropriate positions through structures such as pipe clamps, which can realize sewage transportation without affecting the normal progress of the maintenance work.

[0044] A cleaning mechanism 34 is provided on the top of the housing 1. The cleaning mechanism 34 is provided on one side of the pump body 31. The cleaning mechanism 34 is used to accelerate the flow rate of the sewage in the housing 1 so as to clean the pump body 31 through the flowing sewage, thereby improving the external cleanliness of the pump body 31. The input end of the pump body 31 is connected to the sewage in the housing 1, and the output end of the pump body 31 is connected to the output pipeline 12 so as to suck and output the sewage in the housing 1. The setting of the cleaning mechanism 34 can clean the outside of the pump body 31 through the cleaning mechanism 34 when the pump body 31 is overhauled, thereby reducing the difficulty of overhaul, and also avoiding the normal operation of the pump body 31 being affected by the external adhesion of impurities, thereby improving the reliability of the pump body 31. The pump body 31 can select a suitable type of sewage pump according to needs, for example, a high-efficiency, low-energy submersible sewage pump can be selected according to the flow rate of sewage.

[0045] like Figure 1-Figure 3As shown, optionally, the filtering device includes a first filtering mechanism 21, and the first filtering mechanism 21 includes a filter basket 211 and a first lifting assembly 212. The filter basket 211 includes a bottom plate and a plurality of side plates, and an opening is provided at the top of the filter basket 211 so that sewage can enter the filter basket 211. The filter basket 211 can achieve a preliminary filtering effect, reduce impurities in the sewage, and reduce the impact of impurities on the pump group device 3. The bottom plate and the side plate of the filter basket 211 are provided with a plurality of first filtering holes 2111 so that the filter basket 211 can play a filtering role. The fixed end of the first lifting assembly 212 is arranged at the top of the housing 1, and the movable end of the first lifting assembly 212 is connected to the filter basket 211. The first lifting assembly 212 is used to drive the filter basket 211 to move. The first lifting assembly 212 may include a winding structure and a flexible rope, and the winding structure is erected at the top of the housing 1, one end of the flexible rope is wound around the winding structure, and the other end of the flexible rope is connected to the filter basket 211. The structure of the reeling structure is not limited, as long as it can realize the reeling and unreeling of the flexible rope. The input pipeline 11 is arranged above the top of the filter basket 211 when it is at the lowest position, so that after the filter basket 211 is placed in the housing 1, sewage can be input into the filter basket 211 to ensure reliable filtering of the sewage.

[0046] The input pipeline 11 transports the sewage into the housing 1, and allows the sewage to enter the filter basket 211. The filter basket 211 performs the first filtering action, leaving some impurities in the sewage in the filter basket 211, thereby improving the cleanliness of the sewage flowing out of the filter basket 211 and reducing the impact of impurities on the pump body 31. Since the filter basket 211 is connected to the first lifting assembly 212, the filter basket 211 can be lifted to the top of the housing 1 after filtering the sewage, which can facilitate the inspection of the filter basket 211 on the one hand, and the cleaning of impurities in the filter basket 211 on the other hand, so as to ensure that the filtering effect of the filter basket 211 is continuous and reliable.

[0047] like Figure 3 and Figure 4As shown, optionally, a flip member 214 is provided in the housing 1, and the flip member 214 is a plate-shaped or block-shaped member protruding from the inner wall of the housing 1. Two first lifting assemblies 212 are provided, and the two first lifting assemblies 212 are respectively rotated to connect the connection points of the two opposite first side surfaces of the filter basket 211, so that the filter basket 211 can flip around the straight line where the two connection points are located. The bottom plate area of ​​the filter basket 211 is smaller than the area of ​​the top opening of the filter basket 211 to ensure that flipping can be achieved and reduce interference. The flip member 214 is used to cooperate with the second side surface of the filter basket 211, so that after the filter basket 211 is stuck on one side by the flip member 214, as the first lifting component 212 continues to lift, the height difference between the two sides of the filter basket 211 gradually increases. Since the first lifting component 212 is rotatably connected to the connection between the filter basket 211, the filter basket 211 can be flipped around the straight line where the two connections are located. Therefore, when the height difference between the two ends of the filter basket 211 is large, the filter basket 211 will be flipped toward the flip member 214, so that the opening of the filter basket 211 is facing downward, and the filter basket 211 is turned upside down. The filter basket 211 is turned upside down, which helps to clean the bottom of the filter basket 211 on the one hand, and can pour out the impurities in the filter basket 211 on the other hand, improving the cleaning efficiency.

[0048] The cross section of the filter basket 211 is trapezoidal, so that the sewage can flow out of the filter basket 211 smoothly, avoiding the obstruction of the sewage outflow caused by the filter basket 211 and the inner wall of the housing 1. In addition, the size of the filter basket 211 is smaller than the space in the housing 1 for accommodating the filter basket 211, so that the filter basket 211 can be turned over inside the housing 1 and the sewage outflow efficiency in the filter basket 211 is improved. The length of the flip member 214 extending out of the inner wall of the housing 1 can be adjusted as needed, and the filter basket 211 can be turned over by the locking effect of the flip member 214. The flip member 214 can be a telescopic structure or a fixed structure.

[0049] like Figure 3 and Figure 4 As shown, optionally, the filter device further comprises a second filter mechanism 22, the second filter mechanism 22 comprises a baffle 221, the baffle 221 is vertically arranged between the first filter mechanism 21 and the pump assembly 3, the flip member 214 is arranged on the side of the housing 1 away from the baffle 221, and a push assembly 215 is arranged on the side of the baffle 221 close to the filter basket 211, so that the flip member 214 and the push assembly 215 are arranged on both sides of the filter basket 211. The push assembly 215 is used to push the filter basket 211, so as to assist in the flipping of the filter basket 211 through the push assembly 215, so as to avoid the problem that the filter basket 211 cannot be reliably flipped due to the insufficient height difference caused by the flip member 214 on both ends of the filter basket 211.

[0050] Optionally, the pushing assembly 215 includes a first pushing member 2151 and a second pushing member 2152. In the vertical direction, the first pushing member 2151 and the second pushing member 2152 are respectively arranged above and below the flip member 214. The first pushing member 2151 and the second pushing member 2152 can both be telescopic rod structures. Sufficient clearance is left between the filter basket 211 and the housing 1 and the baffle 221 in the circumferential direction to install the flip member 214 and the pushing assembly 215, and the pushing assembly 215 will not interfere with the filter basket 211 when it is retracted. Since the first pushing member 2151 and the second pushing member 2152 are at different heights, it is convenient to realize the inversion and reset of the filter basket 211 more conveniently by the difference in the pushing position of the filter basket 211, thereby ensuring the reliability of the flipping of the filter basket 211. When the filter basket 211 rises, one side of the filter basket 211 is stuck by the flip piece 214, so that the height of the side of the filter basket 211 close to the pushing assembly 215 is higher than the flip piece 214. At this time, the first pushing member 2151 located above the flip piece 214 extends out to push the filter basket 211 to be flipped upside down; when the filter basket 211 descends, the filter basket 211 is in an upside-down state. After one side of the filter basket 211 is stuck by the flip piece 214, the height of the side of the filter basket 211 close to the baffle 221 is lower than the flip piece 214. At this time, the second pushing member 2152 located below the flip piece 214 extends out to push the filter basket 211 to be reset and flipped.

[0051] like Figure 3-Figure 5As shown, optionally, a dredging component 213 is provided on the inner side of the top of the housing 1, and the dredging component 213 includes a connecting piece 2131, a first dredging piece 2132 and a water spraying piece 2133, which is used to dredge and clean the first filtering mechanism 21. One side of the connecting piece 2131 is connected to the housing 1, and the other side of the connecting piece 2131 is provided with a plurality of first dredging pieces 2132. The first dredging piece 2132 can be cylindrical, and the connecting piece 2131 can be a frame structure, and its shape can be set as needed. The bottom and side wall of the filter basket 211 are both provided with a first filter hole 2111. Since the bottom of the filter basket 211 is mainly used to carry impurities in the sewage, the first filter hole 2111 has a greater risk of being blocked by impurities. The first dredging piece 2132 corresponds to the first filter hole 2111 at the bottom of the filter basket 211, and the diameter of the first dredging piece 2132 is smaller than the diameter of the first filter hole 2111, so as to dredge the first filter hole 2111. The number of the first dredging members 2132 can be set in one-to-one correspondence with the first filter holes 2111 at the bottom of the filter basket 211, so as to achieve dredging of the bottom of the filter basket 211; the first dredging member 2132 can also be set only corresponding to one side of the bottom of the filter basket 211. Since the filter basket 211 will flip over later, the first dredging member 2132 can be set corresponding to the lower end of the bottom when the filter basket 211 flips over, thereby reducing the blockage of the lower end of the bottom due to flipping. The vertical spacing between the dredging component 213 and the flip member 214, the horizontal spacing between the filter basket 211 and the housing 1, and the horizontal spacing between the filter basket 211 and the baffle 221 all need to be large enough to avoid interference when the filter basket 211 flips over.

[0052] There are a plurality of water spraying parts 2133, which are distributed in the housing 1. The water spraying parts 2133 can be arranged on the inner wall of the housing 1 or on the connecting part 2131. The water spraying parts 2133 are used to flush the filter basket 211. The spraying angle of the water spraying parts 2133 can be set as required. Since there are a plurality of water spraying parts 2133, the filter basket 211 can be flushed by some of the water spraying parts 2133, and the baffle 221 can be flushed by some of the water spraying parts 2133. The first dredging part 2132 dredges the first filter hole 2111, and impurities in the first filter hole 2111 at the bottom of the filter basket 211 are poked out. Combined with the flushing effect of the water spraying part 2133 on the filter basket 211, the first filter hole 2111 of the filter basket 211 is further dredged to ensure that the filter basket 211 can normally achieve the filtering effect.

[0053] like Figure 5 and Figure 6As shown, the cross-section of the filter basket 211 is an isosceles trapezoid, so that the area of ​​the bottom of the filter basket 211 is smaller than the area of ​​the top opening, and the side of the filter basket 211 is inclined, so that the filter basket 211 can smoothly discharge sewage out of the filter basket 211 while retaining impurities inside, avoiding the filter basket 211 and the side wall of the shell 1 from being attached to affect the sewage transportation efficiency.

[0054] like Figure 5 and Figure 7 As shown, optionally, the first filtering mechanism 21 further includes a collecting box body 216 and a second lifting assembly 217. The collecting box body 216 is sleeved on the outside of the filter basket 211, and is used to collect impurities in the filter basket 211 to prevent the impurities from falling on the bottom of the housing 1 and increasing the difficulty of cleaning. The top of the collecting box body 216 is provided with a first opening 2161, which is used to place the filter basket 211 in the collecting box body 216, so that the impurities deposited after filtering out the filter basket 211 and the impurities poured out after the filter basket 211 is turned over can be collected through the collecting box body 216, thereby cleaning the impurities around the filter basket 211 and improving the cleanliness. The collecting box body 216 is provided with a second opening 2162 on one side close to the baffle 221, so as to facilitate the movement of sewage toward the baffle 221. The inner wall of the bottom of the collection box body 216 is inclined, and the thickness of the bottom of the collection box body 216 near the baffle 221 is greater than the thickness of the bottom of the collection box body 216 away from the baffle 221, so as to optimize the collection effect of impurities and reduce the risk of impurities falling at the second opening 2162. The second filter mechanism 22 is arranged between the first filter mechanism 21 and the pump assembly device 3. Since the flow direction of sewage is from the first filter mechanism 21 to the second filter mechanism 22, there is a problem of impurities being accumulated at the baffle 221. In other embodiments, one end of the bottom of the collection box body 216 with the second opening 2162 can be made to contact the baffle 221, so that the bottom of the collection box body 216 can scrape the baffle 221 through the second opening 2162, thereby cleaning the impurities at the baffle 221. The fixed end of the second lifting component 217 is fixed to the top of the housing 1, and the movable end of the second lifting component 217 is connected to the collection box body 216. The second lifting component 217 is used to pull the collection box body 216 upward to clean the impurities in the collection box body 216. The lifting height of the filter basket 211 and the collection box body 216 is adjustable, and the impurities can be cleaned and washed.

[0055] like Figure 3-Figure 5As shown, optionally, the second filtering mechanism 22 includes a filter plate 222, a second dredging member 223 and a third lifting assembly 224. The filter plate 222 is tilted, and the first end of the filter plate 222 close to the pump assembly 3 is higher than the second end of the filter plate 222 close to the baffle 221. The filter plate 222 can be a plate-shaped member with a plurality of through holes, so that the sewage can utilize the filtering effect of the filter plate 222 to leave impurities on the filter plate 222. After the sewage flows through the filter plate 222, it flows toward the pump assembly 3 below the filter plate 222.

[0056] The second dredging member 223 is arranged at the second end of the filter plate 222, and a plurality of second filter holes 2211 are provided on the baffle plate 221, and the second dredging member 223 cooperates with the second filter holes 2211. The second dredging member 223 includes a rotating shaft and a plurality of gear parts, the two ends of the rotating shaft are connected to the two sides of the second end of the filter plate 222, the rotating shaft is spaced apart from the upper surface of the filter plate 222, the gear parts are rotatably connected to the rotating shaft, and the axial direction of the rotating shaft extends along the length direction of the baffle plate 221, so that the plurality of gear parts can cooperate with the second filter holes 2211 on the baffle plate 221. The gear teeth of the gear parts can extend into the second filter holes 2211, and the second filter holes 2211 are dredged by the gear teeth. The second filter holes 2211 are provided with a plurality of columns, and each column of the second filter holes 2211 extends along the height direction of the baffle plate 221, and each column of the second filter holes 2211 corresponds to a gear part, and the spacing between two adjacent second filter holes 2211 in the same column is determined according to the modulus and other parameters of the gear parts. The second filter holes 2211 may be provided with a certain inclined surface to ensure that they can be meshed with the gear member. In this embodiment, the meshing between each column of second filter holes 2211 and the gear member is similar to the meshing form between a gear and a rack.

[0057] like Figure 3-Figure 5 As shown, the fixed end of the third lifting component 224 is arranged at the top of the housing 1, the movable end of the third lifting component 224 is connected to the filter plate 222, and the second dredging member 223 is used to dredge the second filter hole 2211 when the filter plate 222 moves. When the third lifting component 224 lifts the filter plate 222, as the filter plate 222 rises, the gear member rotates while cooperating with the second filter hole 2211, so that the gear member can rotate to achieve the meshing of the second filter holes 2211 at different heights, that is, the gear teeth extend into the second filter holes 2211, so as to achieve the dredging of the second filter holes 2211 at different heights, so as to achieve the dredging of the baffle 221 while lifting the filter plate 222 when impurities above the filter plate 222 need to be cleaned.

[0058] A slider is provided at the end of the filter plate 222 close to the housing 1, and a guide groove 14 is provided at the corresponding position of the housing 1. The slider is slidably connected in the guide groove 14 to keep the filter plate 222 moving vertically. The length of the guide groove 14 can be set as needed, and can be connected to the top of the housing 1 so that the filter plate 222 can be completely separated from the housing 1, which is convenient for operators to inspect and clean the bottom of the filter plate 222. The guide groove 14 may also not be connected to the top of the housing 1 to avoid inconvenience in the meshing and installation of the second dredging member 223 and the second filter hole 2211 after the filter plate 222 is separated from the housing 1.

[0059] like Figure 3-Figure 5 As shown, in this embodiment, the diameters of the first filter hole 2111, the second filter hole 2211, and the through hole opened on the filter plate 222 are gradually reduced, and the sewage output from the filter basket 211 can be filtered twice through the baffle 221, so that the impurities with larger volume are left on the side of the baffle 221 close to the filter basket 211, and are cleaned to the outside of the shell 1 through the collection box 216; the sewage is filtered for the third time on the filter plate 222, and because the filter plate 222 is inclined, the impurities can be left above the filter plate 222, and the sewage flows to the bottom of the filter plate 222 to separate the sewage from the impurities; when cleaning the impurities on the filter plate 222, the filter plate 222 is driven to move upward by the third lifting component 224, so that the second dredging member 223 set at the second end of the filter plate 222 can dredge the second filter hole 2211 on the baffle 221, thereby improving the cleanliness of the baffle 221, so that the baffle 221 can reliably achieve the filtering effect. It can be understood that the inclination angle of the filter plate 222 can be set as needed, and the maximum height of the end of the filter plate 222 is not less than the maximum height of the sewage, so that the filter plate 222 can play a filtering role; or, a partition plate (not shown in the figure) is arranged between the second filter mechanism 22 and the pump unit 3, and the partition plate is arranged above one end of the filter plate 222 close to the pump unit 3, so that the sewage can only flow to the pump unit 3 after passing through the filter plate 222.

[0060] like Figure 3-Figure 5As shown, optionally, the pump assembly device 3 further includes a filter layer 35, the filter layer 35 is connected to the inner wall of the housing 1, the filter layer 35 is parallel to the bottom of the housing 1, and the filter layer 35 is arranged between the top and the bottom of the housing 1 in the longitudinal direction. The filter layer 35 is used to further filter the area around the pump body 31, so that there is a filtering effect between the upper layer and the lower layer of the end of the housing 1 where the pump assembly device 3 is arranged, so that the cleanliness of the upper layer inside the housing 1 is higher than the cleanliness of the lower layer, so that the pump body 31 can be lifted by the driving mechanism 33, and the pump body 31 can be cleaned above the filter layer 35. The filter layer 35 is provided with an avoidance hole 351, and the avoidance hole 351 cooperates with the float 32, so that the pump body 31 and the float 32 can pass through the avoidance hole 351 and move from the lower layer of the housing 1 to the upper layer. The size of the avoidance hole 351 cooperates with the float 32, which can prevent the sewage below the filter layer 35 from directly flowing to the upper layer through the avoidance hole 351 when cleaning the pump body 31, thereby affecting the cleaning effect. The cleaning mechanism 34 is arranged above the filter layer 35, and is used to accelerate the water flow velocity of the upper layer with higher cleanliness. By accelerating the flowing water flow, the pump body 31 is cleaned, and the cleanliness of the outside of the pump body 31 is improved, which not only helps to ensure the reliable operation of the pump body 31, but also facilitates the maintenance of the pump body 31. The filter layer 35 is a plate-shaped member provided with a third filter hole 352. The filter layer 35 is detachably connected to the side wall of the housing 1, and the connection method is not limited. The diameter of the third filter hole 352 is smaller than the diameter of the through hole of the filter plate 222. The size of the avoidance hole 351 can be passed by the operator to avoid inconvenience in maintenance. The filter layer 35 is flush with the height of the bottom of the partition plate, so that the sewage flows to the pump group device 3 through the filter plate 222, and then is filtered through the filter layer 35 to improve the cleanliness of the sewage and optimize the cleaning effect of the pump body 31.

[0061] The pump assembly 3 further comprises a level gauge 15, which is electrically connected to the pump body 31 so as to achieve suction according to the amount of sewage in the housing 1. Multiple pump assembly 3 can be provided to improve the reliability of sewage treatment.

[0062] like Figure 3-Figure 5As shown, the driving mechanism 33 includes a first motor 331, a lead screw 332 and a nut member 333. The first motor 331 is fixedly connected to the top of the housing 1. The output end of the first motor 331 is transmission-connected to one end of the lead screw 332. The lead screw 332 extends in the vertical direction to drive the pump body 31 to move up and down. The other end of the lead screw 332 is rotationally connected to the bottom of the housing 1, and the nut member 333 is sleeved on the lead screw 332. A limiter 18 is provided on the outer periphery of the lead screw 332. The limiter 18 is provided on one side of the nut member 333 to limit the rotation of the nut member 333, so that the rotation of the lead screw 332 can drive the nut member 333 to move up and down in the vertical direction. A protrusion 3331 is provided on one side of the nut member 333, and the protrusion 3331 is connected to the pump body 31 to leave a distance between the pump body 31 and the screw 332, so that the float member 32 can move with the movement of the pump body 31 to avoid interference between the float member 32 and the screw 332 or the limit member 18.

[0063] In this embodiment, the cross section of the float 32 is circular, so the avoidance hole 351 is also circular, so that the float 32 can pass through. The diameter of the float 32 is equal to or slightly smaller than the diameter of the avoidance hole 351, so that the float 32 can pass through the avoidance hole 351, and the cooperation between the float 32 and the avoidance hole 351 can reduce the situation that the sewage below the filter layer 35 flows directly to the top of the filter layer 35 without being filtered by the filter layer 35. The avoidance hole 351 is relatively closed by the float 32, so that the sewage cleaned by the cleaning mechanism 34 above the filter layer 35 is the sewage with the highest cleanliness in the shell 1, and the cleaning effect is optimized.

[0064] like Figure 3-Figure 5 As shown, the cleaning mechanism 34 includes a second motor 341, a rotating shaft 342 and blades 343. The second motor 341 is arranged on the top of the shell 1. The output end of the second motor 341 is connected to one end of the rotating shaft 342, and the other end of the rotating shaft 342 is connected to the blades 343, so that the blades 343 can rotate around the axis of the rotating shaft 342, thereby driving the sewage around the blades 343 to accelerate the flow, so as to play the role of water flow impact cleaning on the pump body 31 on one side of the cleaning mechanism 34, thereby improving the cleanliness and reliability of the pump body 31.

[0065] It can be understood that the shell 1 can be divided into three areas, and the first filter mechanism 21, the second filter mechanism 22 and the pump group device 3 are arranged in sequence along the flow direction of the sewage, and the three areas can be separated by the baffle 221 and the partition plate. A movable plate and a fixed plate are provided on the top of each area shell 1. For example, above the first filter mechanism 21, the first lifting assembly 212 and the connecting member 2131 and other structures are connected by the fixed plate, and the top of the shell 1 above the first filter mechanism 21 is closed by the cooperation of the movable plate and the fixed plate. When maintenance is required, the movable plate is moved to facilitate observation and inspection of the first filter mechanism 21 and to enter the shell 1 for maintenance. The movable plate is actively connected to the shell 1 and can be opened by flipping; the fixed plate is assembled and connected to the shell 1, and can be disassembled and removed when the internal structure of the shell 1 needs to be taken out. The sewage pump station is provided with necessary control mechanisms to enable the functions of each part of the structure to be realized normally. The first lifting assembly 212, the second lifting assembly 217 and the third lifting assembly 224 can adopt the same structure, or different structures can be selected according to actual conditions. The dimensions and other parameters of each structure of the sewage pumping station can be determined according to actual conditions.

[0066] The implementation principle of a sewage pump station in an embodiment of the present application is as follows: sewage enters the interior of the shell 1 through the input pipe 11, and first, the larger impurities in the sewage are retained in the filter basket 211 through the first filtering mechanism 21; then, the sewage passes through the baffle 221, and is filtered twice through the second filter hole 2211, and then filtered for the third time through the filter plate 222. After that, the sewage flows to the pump group device 3, and is transported to the output pipe 12 through the pump body 31 to be discharged from the shell 1. When cleaning the sewage pump station, at the first filter mechanism 21, the filter basket 211 is lifted by the first lifting component 212, so that the operator can clean the impurities inside the filter basket 211 on the top of the shell 1; the filter basket 211 continues to be lifted and will be pressed against one side by the flip member 214 to be flipped, and the impurities in the filter basket 211 are poured into the collection box body 216 for easy cleaning, and the filter basket 211 is cleaned by the dredging component 213; the filter plate 222 of the second filter mechanism 22 is lifted by the third lifting component 224 to clean the impurities on the upper surface of the filter plate 222, and at the same time, the second filter hole 2211 of the baffle 221 can be dredged by the second dredging component 223; the pump body 31 is lifted to the top of the filter layer 35 by the driving mechanism 33, and the cleaning mechanism 34 is started to clean the pump body 31 for easy maintenance of the pump body 31. The sewage pump station reduces impurities in sewage through the filtering effect in the shell 1, thereby improving the reliability of the pump body 31; and improves the cleanliness of the pump body 31 by cleaning the pump body 31, which helps to ensure the reliable operation of the pump body 31.

[0067] like Figure 8As shown, in the second aspect, the embodiment of the present application discloses a construction method of a sewage pumping station (hereinafter referred to as "construction method"), which is applied to the above-mentioned sewage pumping station. The construction method comprises the following steps: S10, pre-installation of the pump assembly, pre-assembling the pump body 31 with the float 32 and the drive mechanism 33 respectively, and then assembling and connecting the drive mechanism 33 and the cleaning mechanism 34 in the housing 1; S20, digging a placement groove, and placing the housing 1 as a whole in the placement groove; S30 , installing the filter device: selectively installing the filter device in the housing 1 according to the volume of the placement tank and the housing 1 .

[0068] This construction method can pre-install the pump assembly 3, install the pump assembly 3 inside the housing 1, and after the installation is completed, the pump assembly 3 can be moved to the placement tank by moving the housing 1 as a whole. In this embodiment, since the filter device and the pump assembly 3 are relatively independent structures, it is possible to selectively determine whether to install the filter device in the housing 1 according to the size of the placement tank and the size of the housing 1, and to determine whether to install one or both of the first filter mechanism 21 and the second filter mechanism 22, thereby improving the applicability to different placement tanks, so that the sewage pump station can achieve sewage treatment in placement tanks of different sizes, and will not affect the normal transportation function of the pump assembly 3 for sewage. At the same time, according to actual conditions, after installing the filter device and the pump assembly 3, the first filter mechanism 21 or the second filter mechanism 22 can be selectively activated to adapt to the treatment of sewage with different water volumes, different impurity contents, and different flow rates.

[0069] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
