Technical Field

[0001] This application relates to the technical field of filter cleaning devices for SVG equipment, and more particularly to a filter cleaning device. Background Technology

[0002] In power generation systems, SVG typically refers to a Static Var Generator (SVC), also known as a Static Var Compensator. This device is used in power systems to dynamically regulate and compensate reactive power, thereby improving the stability and efficiency of the power system. As a crucial component of a power plant, SVG equipment requires regular maintenance; its filters need to be cleaned periodically or irregularly to ensure its proper operation.

[0003] Existing methods for cleaning filter screens typically involve workers using handheld high-pressure water guns to spray and wash away dirt from the filter screens. However, the high pressure of the water jets makes it difficult for workers to control them, resulting in a time-consuming and labor-intensive cleaning process. Furthermore, the filter screens are prone to damage when subjected to high-pressure water jets. Utility Model Content

[0037] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0039] In power generation systems, SVG typically refers to a Static Var Generator, also known as a Static Var Compensator (SVC). This is a device used in power systems to dynamically regulate and compensate reactive power, thereby improving the stability and efficiency of the power system. As a crucial piece of equipment in a power plant, SVG devices require regular maintenance; and the filters of SVG devices need to be cleaned regularly or irregularly to ensure their proper operation.

[0040] Traditionally, the filter screen is cleaned by operators using high-pressure tap water. However, manual cleaning is time-consuming and labor-intensive. Furthermore, due to the lack of professional tools, it is difficult to ensure that the filter screen is thoroughly and evenly cleaned. Sometimes, some dirt may remain, or the filter media may be damaged when the high-pressure water jet washes over it.

[0041] Reference Figures 1 to 8 As shown, this application embodiment provides a filter cleaning device, including a housing 1, a first conveyor belt 21, a second conveyor belt 22, and a driving member 3; the housing 1 has a cleaning chamber formed inside, which can contain liquid, and an inlet / outlet 13 communicating with the cleaning chamber is provided on one side of the housing 1, which is used for the filter 6 to enter and leave the cleaning chamber; the first conveyor belt 21 and the second conveyor belt 22 are both disposed in the cleaning chamber and are arranged opposite to each other, and the inlet / outlet 13 is disposed between the first conveyor belt 21 and the second conveyor belt 22 so that the first conveyor belt 21 and the second conveyor belt 22 can be used to clamp the filter 6, and the surface of the first conveyor belt 21 and the second conveyor belt 22 are provided with brushes 23; the driving member 3 is connected to the first conveyor belt 21 and the second conveyor belt 22 to drive the first conveyor belt 21 and the second conveyor belt 22 to rotate.

[0042] After the cleaning chamber is filled with liquid, the filter screen 6 enters the cleaning chamber through the inlet 13. The drive unit 3 drives the first conveyor belt 21 and the second conveyor belt 22 to rotate, so that the brush 23 can brush the filter screen in the cleaning chamber. The first conveyor belt 21 and the second conveyor belt 22 clean both sides of the filter screen 6 at the same time, improving the cleaning efficiency. Moreover, there is no need to use high-pressure water to impact the filter screen 6, which can avoid damage to the filter screen 6.

[0043] Specifically, the outer casing 1 can be a rectangular box structure with a narrow inlet 13 at the top, the width of which is slightly greater than the thickness of the filter screen 6, so that the filter screen 6 can be inserted into or removed from the cleaning chamber through the strip-shaped inlet 13.

[0044] The first conveyor belt 21 and the second conveyor belt 22 mentioned above can both be made of flexible rubber belts. The surface of the belt body is embedded with hard nylon brushes 23. There are multiple brushes 23 on each belt body. The multiple brushes 23 are arranged along the circumference of the belt body. When the first conveyor belt 21 and the second conveyor belt 22 rotate, the brushes on the belt body move and brush the filter screen 6.

[0045] The first conveyor belt 21 and the second conveyor belt 22 are arranged opposite to each other and spaced apart. The distance between the belts of the first conveyor belt 21 and the second conveyor belt 22 that are close to each other can be slightly greater than the thickness of the filter screen 6. The brush 23 is made of flexible bristles. After the filter screen 6 is inserted into the cleaning chamber, the belts of the first conveyor belt 21 and the second conveyor belt 22 are spaced apart from the filter screen 6, and the brush 23 on the first conveyor belt 21 and the brush 23 on the second conveyor belt 22 respectively abut against the two sides of the filter screen 6 so that the first conveyor belt 21 and the second conveyor belt 22 can hold the filter screen 6.

[0046] After the first conveyor belt 21 and the second conveyor belt 22 clamp the filter screen 6, the filter screen 6 remains in a stable position within the cleaning chamber, preventing the filter screen 6 from flipping due to the rotation of the first conveyor belt 21 and the second conveyor belt 22. Clean water or cleaning fluid can be injected into the cleaning chamber to clean the filter screen 6.

[0047] The outer casing 1 can optionally be equipped with a water inlet, which communicates with the cleaning chamber, allowing operators to inject liquid into the cleaning chamber through the inlet. When the filter screen 6 is in the cleaning chamber, it is submerged below the liquid surface. Alternatively, operators can inject liquid into the cleaning chamber through the inlet / outlet 13. After liquid is injected into the cleaning chamber, the first conveyor belt 21 and the second conveyor belt 22 are immersed in the liquid. The rotation of the first conveyor belt 21 and the second conveyor belt 22 drives the liquid flow, which also has a flushing effect on the filter screen 6, thus helping to remove dirt from the filter screen 6.

[0048] The aforementioned driving component 3 can be a motor. The output end of the motor is connected to the rotating shaft of the first conveyor belt 21 and the second conveyor belt 22 through gear or belt drive, so that when the output end of the motor rotates, it can drive the first conveyor belt 21 and the second conveyor belt 22 to rotate.

[0049] In specific use, the filter cleaning device provided in this embodiment inserts the filter 6 vertically into the gap between the first conveyor belt 21 and the second conveyor belt 22 from the inlet / outlet 13. Then, the drive unit 3 is activated, causing the first conveyor belt 21 to rotate clockwise and the second conveyor belt 22 to rotate counterclockwise. The brushes 23 of the first conveyor belt 21 and the brushes 23 of the second conveyor belt 22 roll along the surface of the filter 6, removing dirt from the filter 6 through the friction of the brushes 23 and the scouring effect of the liquid flow.

[0050] The filter cleaning device provided in this embodiment includes a first conveyor belt 21 and a second conveyor belt 22 inside a housing 1. A drive unit 3 is mounted on the housing 1 to drive the first conveyor belt 21 and the second conveyor belt 22 to rotate. The inlet / outlet 13 is connected to the cleaning chamber inside the housing 1. When the filter screen 6 enters the cleaning chamber through the inlet / outlet 13, it is held by the first conveyor belt 21 and the second conveyor belt 22. As the first conveyor belt 21 and the second conveyor belt 22 rotate, the brushes 23 on both sides of the filter screen 6 move, and the liquid in the cleaning chamber flows. The friction of the brushes 23 and the flow of the liquid remove dirt from the filter screen 6. The rotation of the first conveyor belt 21 and the second conveyor belt 22 can simultaneously clean both sides of the filter screen 6 and drive the flow of liquid in the cleaning chamber to assist in cleaning the filter screen 6, improving the efficiency and cleanliness of cleaning the filter screen 6, and avoiding damage to the filter screen 6 caused by using high-pressure water jets to wash it.

[0051] Reference Figures 1 to 5 As shown, in some embodiments, the first conveyor belt 21 includes a first belt body, a first roller 211, and a second roller 212; the second conveyor belt 22 includes a second belt body, a third roller 221, and a fourth roller 222; the first roller 211 and the second roller 212 are spaced apart along the length of the outer casing 1, and the two ends of the first belt body are sleeved on the first roller 211 and the second roller 212, and the outer peripheral surface of the first belt body is provided with a brush 23; the third roller 221 and the fourth roller 222 are spaced apart along the length of the outer casing 1, and the two ends of the second belt body are sleeved on the third roller 221 and the fourth roller 222, and the outer peripheral surface of the second belt body is provided with a brush 23; the first roller 211 and the third roller 221 are connected to each other by a synchronous belt 24, and the driving member 3 is drivenly connected to at least one of the first roller 211, the second roller 212, the third roller 221, and the fourth roller 222.

[0052] With this configuration, the synchronous belt 24 makes the first roller 211 and the third roller 221 rotate synchronously, so that the first conveyor belt 21 and the second conveyor belt 22 rotate at the same speed, and so that the force applied to both sides of the filter screen 6 is equal when the first conveyor belt 21 and the second conveyor belt 22 rotate, thus preventing the filter screen 6 from shaking.

[0053] Specifically, the first roller 211, the second roller 212, the third roller 221, and the fourth roller 222 are all cylindrical rollers. The first roller 211 and the second roller 212 can be spaced apart along the length of the outer shell 1. The first belt is an annular belt, which is fitted over the outside of the first roller 211 and the second roller 212 to form a first conveyor belt 21 extending along the length of the outer shell 1. The third roller 221 and the fourth roller 222 can be spaced apart along the length of the outer shell 1. The second belt is an annular belt, which is fitted over the outside of the third roller 221 and the fourth roller 222 to form a second conveyor belt 22 extending along the length of the outer shell 1. The first conveyor belt 21 and the second conveyor belt 22 are arranged opposite to each other and spaced apart along the length of the outer shell 1, and a clamping space for clamping the filter screen 6 is formed between the first belt and the second belt.

[0054] The first roller 211 and the third roller 221 are arranged opposite each other along the width direction of the outer casing 1. The synchronous belt 24 can be a rubber belt, which is fitted over the outside of the first roller 211 and the third roller 221. The rubber belt drives the first roller 211 and the second roller 212 to rotate synchronously through friction. The first roller 211 and the third roller 221 can rotate in the same direction, or the rubber belt can be arranged in a figure-eight shape with its two ends fitted over the first roller 211 and the third roller 221 respectively, so that the first roller 211 and the third roller 221 rotate in opposite directions.

[0055] Alternatively, the timing belt 24 can be a toothed belt, with gears on both the first roller 211 and the third roller 221. The toothed belt meshes with the first roller 211 and the third roller 221 so that the first roller 211 and the third roller 221 rotate synchronously via the timing belt 24.

[0056] The drive unit 3 can be selectively connected to the first roller 211. When the first roller 211 rotates, the second roller 212 rotates synchronously under the action of the first belt, the third roller 221 rotates synchronously with the first roller 211 under the action of the synchronous belt, and the fourth roller 222 rotates synchronously under the action of the second belt, so that the first conveyor belt 21 and the second conveyor belt 22 rotate synchronously. That is, the first roller 211 and the second roller 212 can rotate synchronously through the first belt, the third roller 221 and the fourth roller 222 can rotate synchronously through the second belt, and the first roller 211 and the third roller 221 can rotate synchronously through the synchronous belt 24, so that if any one of the first roller 211, the second roller 212, the third roller 221 and the fourth roller 222 rotates, the other three rollers will rotate synchronously.

[0057] Reference Figures 1 to 4As shown, in some embodiments, the outer casing 1 is also provided with a water supply pipe 4 and a drain valve 5. Both the water supply pipe 4 and the drain valve 5 are connected to the cleaning chamber. The water supply pipe 4 supplies liquid into the cleaning chamber, and the drain valve 5 allows liquid to flow out of the cleaning chamber when it is opened. The driving component 3 includes a hydraulic motor, which is connected to the water supply pipe 4 so that the liquid in the water supply pipe 4 flows into the cleaning chamber through the hydraulic motor. The hydraulic motor uses the pressure of the liquid in the water supply pipe 4 to drive the first conveyor belt 21 and the second conveyor belt 22 to rotate.

[0058] With this configuration, the water supply pipe 4 is connected to an external water source, the drain valve 5 is located at the bottom of the outer casing 1, and the hydraulic motor is integrated into the water supply pipe 4. The hydraulic motor uses water pressure to drive the first conveyor belt 21 or the second conveyor belt 22 to rotate, so that the hydraulic motor does not need an external power supply, reducing the energy consumption of the filter cleaning device during use.

[0059] Specifically, the water supply pipe 4 can be a steel pipe, and a flange interface is provided at the water inlet 41 so that the water inlet 41 can be connected to the water supply device. The hydraulic motor is an actuator in a hydraulic system, converting the liquid pressure energy provided by the hydraulic pump into the mechanical energy torque and speed of its output shaft. The hydraulic motor can be a cycloidal hydraulic motor, and the output shaft of the hydraulic motor is connected to the synchronous belt 24 via a coupling.

[0060] The drain valve 5 is located at the bottom of the outer casing 1. When the drain valve 5 is opened, the liquid in the cleaning chamber is discharged through the drain valve 5. The flow rate of the drain valve 5 is less than or equal to the flow rate of the water supply pipe 4, so that when the water supply pipe 4 supplies water to the cleaning chamber and the drain valve 5 is opened, the amount of liquid in the cleaning chamber can remain stable.

[0061] When the filter cleaning device is in use, the water supply pipe 4 continuously supplies water to the cleaning chamber. After the liquid in the cleaning chamber reaches the required amount, the drain valve 5 is opened to continuously drain the liquid, so that the liquid in the cleaning chamber maintains a dynamic balance. The liquid in the water supply pipe 4 continuously drives the output end of the hydraulic motor to rotate, so that the hydraulic motor continuously drives the first conveyor belt 21 and the second conveyor belt 22 to rotate and clean the filter screen 6.

[0062] Reference Figures 1 to 4 As shown, in some embodiments, the inlet / outlet 13 is located on the top side of the housing 1, the hydraulic motor is mounted on the side of the housing 1, a first roller 31 is mounted on the top side of the hydraulic motor, and a second roller 32 is rotatably mounted on the top side of the housing 1. The second roller 32 is connected to at least one of the first conveyor belt 21 and the second conveyor belt 22. The first roller 31 and the second roller 32 are connected by a belt so that when the hydraulic motor drives the first roller 31 to rotate, it drives the second roller 32 to rotate synchronously.

[0063] This design allows the mounting belt to be elastic and deformable, absorbing the vibrations from the rotation of the first roller 31 driven by the hydraulic motor. This avoids vibration problems caused by direct mechanical connection and improves transmission smoothness. Furthermore, the first roller 31 and the second roller 32 are located on the outside of the housing 1, without occupying space inside the housing 1.

[0064] Specifically, the hydraulic motor is bolted to the side of the housing 1 along the horizontal direction. The output shaft of the hydraulic motor extends vertically upward. The first roller 31 and the second roller 32 can both be gears. The mounting belt is a toothed belt, so that the first roller 31 and the second roller 32 are engaged with the mounting belt.

[0065] Alternatively, both the first roller 31 and the second roller 32 can be cylindrical, and the mounting belt can be an annular belt. The mounting belt is fitted around the outside of the first roller 31 and the second roller 32, and the mounting belt makes the first roller 31 and the second roller 32 rotate synchronously under the action of friction.

[0066] The aforementioned water supply pipe 4 is connected to the hydraulic motor. During the process of liquid entering the cleaning chamber through the water supply pipe 4, the liquid will pass through the hydraulic motor, allowing the hydraulic motor to utilize the pressure of the liquid inside the water supply pipe 4.

[0067] The second roller 32 can be fixedly connected to the shaft of the first conveyor belt 21 via a coupling, or the second roller 32 can be fixedly connected to the shaft of the second conveyor belt 22 via a coupling, or the second roller 32 can be connected to the shafts of the first conveyor belt 21 and the second conveyor belt 22 via gear transmission, so that the second roller 32 can drive the first conveyor belt 21 and the second conveyor belt 22 to rotate when it rotates.

[0068] When the first conveyor belt 21 includes a first roller 211 and a second roller 212, and the second conveyor belt 22 includes a third roller 221 and a fourth roller 222, a through hole can be provided on the top side of the outer casing 1. The through hole can be arranged opposite to the first roller 211, so that the rotating shaft of the second roller 32 is fixedly connected to the first roller 211 through the through hole; or the through hole can be arranged opposite to the second roller 212, so that the rotating shaft of the second roller 32 is fixedly connected to the second roller 212 through the through hole; or the through hole can be arranged opposite to the third roller 221, so that the rotating shaft of the third roller 221 is fixedly connected to the third roller 221 through the through hole; or the through hole can be arranged opposite to the fourth roller 222, so that the rotating shaft of the second roller 32 is fixedly connected to the fourth roller 222 through the through hole.

[0069] After the above-mentioned hydraulic motor is started, its output shaft drives the first roller 31 to rotate, and drives the second roller 32 to rotate synchronously through the installed belt. The second roller 32 is rigidly connected to the third drum 221, thereby driving the second conveyor belt 22 to operate. Since the first drum 211 and the third drum 221 have been linked by the synchronous belt 24, the first conveyor belt 21 and the second conveyor belt 22 achieve two-way synchronous traction.

[0070] Referring to Figure 1 As shown, in some embodiments, one end of the water delivery pipe 4 is a water outlet connected to the cleaning chamber, and the other end is a water inlet 41. The hydraulic motor is arranged between the water inlet 41 and the water outlet, and a manual valve 42 is provided between the hydraulic motor and the water inlet 41.

[0071] With this setting, after the external water source is connected to the water inlet 41, the manual valve 42 controls the flow rate of the water flowing into the hydraulic motor. After the water flow drives the hydraulic motor to rotate, it enters the cleaning chamber from the water outlet. Adjusting the manual valve 42 can simultaneously change the pressure of the liquid flowing through the water delivery pipe 4 to adjust the rotation speed of the output shaft of the liquid motor, realizing the linkage control of the cleaning parameters.

[0072] Specifically, the water delivery pipe 4 includes two pipe segments. One pipe segment is connected between the housing 1 and the hydraulic motor, and the other pipe segment is connected to the hydraulic motor. When the liquid supplies water to the cleaning chamber through the water delivery pipe 4, the liquid will flow through the hydraulic motor, causing the output end of the hydraulic motor to rotate.

[0073] One end of the above-mentioned water delivery pipe 4 is a water outlet connected to the cleaning chamber, and the other end is a water inlet 41. The hydraulic motor is arranged between the water inlet 41 and the water outlet, and a manual valve 42 is provided between the hydraulic motor and the water inlet 41. The manual valve 42 includes a valve body and a handle. The valve body is connected inside the water delivery pipe 4, and turning the handle can adjust the angle of the valve plate inside the valve body to adjust the flow rate of the liquid passing through the manual valve 42.

[0074] Referring to Figure 1 、 Figure 6 and Figure 7 As shown, in some embodiments, the housing 1 includes a first housing 11 and a second housing 12. The first housing 11 and the second housing 12 are arranged opposite to each other and connected to each other. The space between the first housing 11 and the second housing 12 forms a cleaning chamber; strip-shaped grooves 131 are provided at the edges of the top sides of the first housing 11 and the second housing 12, and the two strip-shaped grooves 131 are arranged opposite to each other to form an entrance 13 by splicing.

[0075] With this setting, the first housing 11 and the second housing 12 are designed in a split type, which is convenient for installing the first conveyor belt 21 and the second conveyor belt 22 between the first housing 11 and the second housing 12.

[0076] Specifically, the outer shell 1 is composed of a first shell 11 and a second shell 12 joined together, with strip grooves 131 opened on the top of each shell, forming a complete inlet / outlet 13 after joining. The first shell 11 and the second shell 12 can both be rectangular box structures, and each of the first shell 11 and the second shell 12 has an opening on one side. The sides of the first shell 11 and the second shell 12 with openings fit together, so that the space inside the first shell 11 and the space inside the second shell 12 together define the cleaning chamber.

[0077] Both the first housing 11 and the second housing 12 have strip grooves 131 on their adjacent edges. The strip groove 131 on the first housing 11 is connected to the internal space of the first housing 11, and a notch is formed on the side wall of the strip groove 131 facing the second housing 12. The strip groove 131 on the second housing 12 is connected to the internal space of the second housing 12, and a notch is formed on the side wall of the strip groove 131 facing the first housing 11. After the first housing 11 and the second housing 12 are fitted together, the two strip grooves 131 are spliced ​​together, and the two notches are arranged opposite each other and connected to each other, so that the two strip grooves 131 form an entrance 13.

[0078] Reference Figure 1 , Figure 6 and Figure 7 As shown, in some embodiments, along the opposite direction of the first housing 11 and the second housing 12, the groove wall of the strip groove 131 is recessed to form a pick-and-place groove 141, and the two pick-and-place grooves 141 are arranged opposite each other to splice together to form a pick-and-place opening 14.

[0079] With this configuration, the operator can insert tools or fingers through the access port 14 to adjust the position of the filter screen 6 in the cleaning chamber, and easily remove the filter screen 6 from the cleaning chamber.

[0080] Specifically, the groove walls of the strip-shaped grooves 131 of the first housing 11 and the second housing 12 are recessed inward to form a pick-and-place groove 141, which, when joined together, forms a pick-and-place opening 14. The pick-and-place groove 141 can be a rectangular recess, with the openings of the two pick-and-place grooves 141 facing each other and communicating with the cleaning chamber, so that the two pick-and-place grooves 141, when joined together, can form a pick-and-place opening 14 communicating with the cleaning chamber. The size of the pick-and-place opening 14 in the direction from the first housing 11 to the second housing 12 is larger than the size of the inlet / outlet 13, and the pick-and-place opening 14 can accommodate the fingers of the operator, making it convenient for the operator to grasp the filter screen 6.

[0081] Reference Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the housing 1 further includes a seal 15, which is disposed at the connection between the first housing 11 and the second housing 12 and is sealed to the first housing 11 and the second housing 12.

[0082] With this configuration, the seal 15 can seal the connection between the first housing 11 and the second housing 12, improving the sealing performance of the outer shell 1 and preventing liquid leakage from the cleaning chamber.

[0083] Specifically, the sealing element 15 is an elastic rubber strip, embedded in a groove at the mating edge of the first housing 11 and the second housing 12 to achieve a seal between them. The sealing element 15 extends along the edges of the first housing 11 and the second housing 12. When the first housing 11 and the second housing 12 are connected to each other, the opposite sides of the first housing 11 and the second housing 12 abut against the sealing element 15, thus sealing the sealing element 15 with the first housing 11 and the second housing 12. The sealing element 15 can be optionally bonded to the first housing 11 and abut against the second housing 12, or it can be optionally bonded to the second housing 12 and abut against the first housing 11.

[0084] Reference Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the first housing 11 is provided with a first groove, and the second housing 12 is provided with a second groove. The first groove and the second groove are arranged opposite to each other. When the first housing 11 and the second housing 12 are fitted together, the sealing member 15 is embedded in the first groove and the second groove and is sealed to the first groove and the second groove.

[0085] With this configuration, the first and second grooves are located at the joint between the first housing 11 and the second housing 12. After the first housing 11 and the second housing 12 are connected, the first and second grooves form a channel structure, which confines the seal 15 within the channel structure. The first and second grooves serve to position and guide the seal 15 when it is positioned between the first housing 11 and the second housing 12.

[0086] Specifically, the first groove extends along the edge of the first housing 11, and the second groove extends along the edge of the second housing 12. When the first housing 11 and the second housing 12 are closed, the first groove and the second groove form a complete channel structure. The seal 15 is confined within the channel structure, and the seal 15 is in close contact with the inner wall of the channel structure, so that the seal 15 is sealed to the first groove and the second groove.

[0087] When connecting the first housing 11 and the second housing 12, the sealing element 15 can be placed in the first groove first, and then the first housing 11 and the second housing 12 can be fitted together. At this time, the first groove and the second groove are positioned opposite each other, and the portion of the sealing element 15 outside the first groove is placed into the second groove, so that the sealing element 15 is sealed to the inner walls of the first groove and the second groove. Alternatively, when connecting the first housing 11 and the second housing 12, the sealing element 15 can be placed in the second groove first, and when the first housing 11 and the second housing 12 are fitted together, the sealing element 15 outside the second groove can be placed into the first groove.

[0088] Reference Figure 1 As shown, in some embodiments, the first housing 11 and the second housing 12 are detachably connected by fasteners.

[0089] With this configuration, the first housing 11 and the second housing 12 can be detachably connected, facilitating the inspection and maintenance of the first conveyor belt 21 and the second conveyor belt 22 inside the cleaning chamber.

[0090] Specifically, the edge of the first housing 11 can be provided with multiple first protrusions, and the edge of the second housing 12 can be provided with multiple second protrusions. The multiple first protrusions and multiple second protrusions are arranged in a one-to-one correspondence. The fastener can be a buckle. After the first housing 11 and the second housing 12 are attached, the buckle connects the first protrusions and the second protrusions, so that the first housing 11 and the second housing 12 can be detachably connected.

[0091] Alternatively, both the first and second protrusions can be provided with through holes, and the fasteners can be bolts. After the first housing 11 and the second housing 12 are fitted together, the bolts pass through the through holes on the first and second protrusions to connect the first and second protrusions.

[0092] In specific use, the filter cleaning device provided in this application embodiment connects the first housing 11 and the second housing 12 with fasteners; when the drain valve 5 is closed, water is supplied to the cleaning chamber through the water supply pipe 4; when the first conveyor belt 21 and the second conveyor belt 22 are below the liquid surface, the drain valve 5 is opened, and the filter screen 6 is vertically inserted into the gap between the two conveyor belts from the inlet / outlet 13.

[0093] The hydraulic motor drives the first roller 31 to rotate under the pressure of the liquid in the water supply pipe 4. The first roller 31 drives the second roller 32 to rotate through the installed belt. The second roller 32 drives the first roller 211 to rotate. The first roller 211 drives the first belt body to rotate, and the third roller 221 drives the second belt body to rotate, so that the first conveyor belt 21 and the second conveyor belt 22 rotate synchronously. The brushes 23 on the first conveyor belt 21 and the second conveyor belt 22 roll along the surface of the filter screen 6. The dirt on the filter screen 6 is removed by the friction of the brushes 23 and the flushing effect of the liquid flow.
