[0002] In industries such as chemical, petroleum, food processing, and water treatment, fluids often contain solid particles, suspended matter, or colloids, which can easily lead to filter clogging, affecting production efficiency and product quality.

[0003] Existing filters with anti-clogging structures often experience leaks at the outlet pipe connection during long-term use, which eventually affects the normal operation of the device and consequently its working efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a filter with an anti-clogging structure to solve the problem that existing filters with anti-clogging structures often experience leakage at the outlet pipe connection during long-term use, which affects the normal use of the device and consequently its working efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a filter with an anti-clogging structure, comprising a tank, an inlet pipe, an outlet pipe, a motor, and a drain pipe. The inlet pipe and outlet pipe are fixedly connected to the surface of the tank. The motor and drain pipe are also fixedly connected to the surface of the tank. A clamping structure is provided on the surface of the outlet pipe. This clamping structure includes a connecting plate, the surface of which is fixedly connected to the surface of the outlet pipe. A groove is formed on the surface of the connecting plate, and a clamping block is slidably connected to the inner wall of the groove. A fixing rod is fixedly connected to the inner wall of the groove, and the arc surface of the fixing rod is slidably connected to the surface of the clamping block. An extension plate is fixedly connected to the surface of the clamping block, and a screw is slidably connected to the surface of the extension plate. One end of the screw is threadedly connected to the surface of the connecting plate. The connecting plate serves as the basic component of the clamping structure, fixed to the surface of the outlet pipe, providing a basic structure for the installation and sliding of the clamping block, and is crucial for the connection between the clamping structure and the outlet pipe. The sliding groove and fixing rod provide sliding space for the clamping block, while the fixing rod limits and guides the clamping block, ensuring stable sliding in a specific direction. The clamping block is the component that directly clamps the liquid outlet pipe, clamping and fixing related components on the pipe by moving and fixing it on the surface. The extension plate and screw provide a connection point for the screw, which converts rotation into linear motion through a threaded connection, thereby fixing the clamping block to the connecting plate.

[0006] Furthermore, a protrusion is fixedly connected to the surface of the clamping block, and a recess is formed on the surface of the clamping block. The size of the protrusion matches the size of the recess. The protrusion and recess are designed to cooperate with each other for connection and positioning between multiple clamping blocks, thereby improving the overall integrity and stability of the clamping.

[0007] Furthermore, a pad made of rubber is fixedly connected to the surface of the clamping block. The pad is fixed to the surface of the clamping block, serving to cushion, absorb shock, and protect the clamped component, while also preventing damage to the clamped component during clamping.

[0008] Furthermore, the surface of the sewage pipe is provided with a collection structure, which includes a collection box. The surface of the collection box has a groove, and the inner wall of the groove has a square groove. A slider is slidably connected to the inner wall of the square groove, and a connecting rod is fixedly connected to the inner wall of the square groove. The arc surface of the connecting rod is slidably connected to the surface of the slider. A collection box is fixedly connected to the surface of the slider, and a handle is fixedly connected to the surface of the collection box. The collection box provides an overall framework for the collection structure and is its fundamental component. The groove and square groove provide space for the installation and operation of the collection box. The groove provides overall installation space for the collection structure, and the square groove provides sliding space for the slider, making them key basic structures of the collection structure. The slider connects the collection box and the square groove, converting the movement of the collection box into sliding motion within the square groove. The connecting rod limits and guides the slider, ensuring stable sliding of the slider within the square groove along the connecting rod direction. The collection box is used to collect substances discharged from the sewage pipe and is the core functional component of the collection structure. The handle design allows users to easily pull the collection box, facilitating its movement.

[0009] Furthermore, the inner wall of the square groove is provided with ball bearings, which are made of steel. The ball bearings, mounted on the inner wall of the square groove, reduce the friction of the slider as it slides within the groove, thus improving the smoothness of the sliding motion.

[0010] Furthermore, a spring is fitted onto the arcuate surface of the connecting rod. One end of the spring is fixedly connected to the surface of the slider, and the other end is fixedly connected to the inner wall of the square groove. This spring design allows it to fit over the arcuate surface of the connecting rod, with one end fixed to the slider surface and the other end fixed to the inner wall of the square groove. When the collection box moves, the spring acts as a buffer and provides a restoring function.

[0011] This utility model has the following beneficial effects: This invention utilizes a clamping structure. First, a connecting plate is fixed to the surface of the outlet pipe, and a clamping block is placed within its groove. The clamping block is slidably connected to the inner wall of the groove via a fixing rod, which limits and guides the clamping block. When the clamping block is needed to clamp relevant components on the outlet pipe, it is moved to slide along the groove and the fixing rod to the appropriate position. After the clamping block is in place, the screw is rotated. Since one end of the screw is threaded to the surface of the connecting plate and slidably connected to the extension plate on the surface of the clamping block, rotating the screw pushes the extension plate, thereby fixing the clamping block to the connecting plate. When multiple clamping blocks are used together, a protrusion on the surface of one clamping block can be inserted into a recess on the surface of another clamping block, achieving connection and positioning between the clamping blocks and enhancing clamping stability. The connecting plate serves as the basic component of the clamping structure, fixed to the surface of the outlet pipe, providing a basic structure for the installation and sliding of the clamping blocks, and is crucial for the connection between the clamping structure and the outlet pipe. The sliding groove and fixing rod design provide sliding space for the clamping block, while the fixing rod limits and guides the clamping block, ensuring stable sliding in a specific direction. The clamping block itself is the direct clamping component, clamping and fixing related components on the outlet pipe by moving and fixing it on the surface. The extension plate and screw provide a connection point for the screw, which converts rotation into linear motion via a threaded connection, thus fixing the clamping block to the connecting plate. The protrusion and recess work together to connect and position multiple clamping blocks, improving the overall integrity and stability of the clamping. The pad is fixed to the surface of the clamping block, providing cushioning, shock absorption, and protection for the clamped components. It also prevents damage to the clamped components during clamping. This clamping structure facilitates clamping at the outlet pipe connection, minimizing leakage and further improving the device's operational stability.

[0012] This invention utilizes a collection structure on the surface of a sewage pipe. The collection box is the main component, with grooves on its surface and a slider placed in a square groove on the inner wall of the groove. The slider is slidably connected to the inner wall of the square groove via a connecting rod, which limits and guides the slider. A collection box is fixed to the slider, and a handle on the surface of the collection box facilitates user operation. When the collection box is needed to collect impurities discharged from the sewage pipe, it is pulled by the handle. When the collection box is pulled, the slider slides along the connecting rod within the square groove. Simultaneously, the ball bearings on the inner wall of the square groove reduce the friction of the slider, making the pulling process smoother. A spring is fitted onto the arc surface of the connecting rod, with one end fixed to the slider surface and the other end fixed to the inner wall of the square groove. When the collection box is pulled, the spring is stretched, providing cushioning and resetting. The collection box provides the overall framework for the collection structure and is its fundamental component. The grooves and square grooves provide space for the installation and operation of the collection box. The groove and square slot design provide the overall installation space for the collection structure, while the square slot provides sliding space for the slider, forming a key basic structure for the collection system. The slider connects the collection box and the square slot, converting the movement of the collection box into sliding motion within the square slot. The connecting rod limits and guides the slider, ensuring stable sliding along the connecting rod within the square slot. The collection box collects substances discharged from the drain pipe and is the core functional component of the collection system. The handle allows users to easily pull and move the collection box. Ball bearings, installed on the inner wall of the square slot, reduce friction and improve smooth sliding. A spring, fitted onto the arc surface of the connecting rod, is fixed at one end to the slider surface and the other end to the inner wall of the square slot. When the collection box moves, the spring acts as a buffer and reset mechanism. This collection structure facilitates the collection of filtered dirt and impurities, minimizing environmental pollution and further enhancing the device's environmental friendliness.

The pad 69 is fixed to the surface of the clamping block 64, serving to cushion, absorb shock, and protect the clamped part, while also preventing the clamping block 64 from damaging the clamped part during the clamping process.

[0020] The surface of the sewage pipe 5 is provided with a collection structure 7, which includes a collection box 71. The surface of the collection box 71 has a groove 74, and the inner wall of the groove 74 has a square groove 75. A slider 76 is slidably connected to the inner wall of the square groove 75, and a connecting rod 77 is fixedly connected to the inner wall of the square groove 75.

The connecting rod 77 serves to limit and guide the slider 76, ensuring that the slider 76 slides stably within the square groove 75 along the direction of the connecting rod 77. The collection box 72 is used to collect the material discharged from the drain pipe 5 and is the core functional component of the collection structure 7. The handle 73 allows the user to easily pull the collection box 72, facilitating its movement.

[0021] The inner wall of the square groove 75 is provided with ball bearings 79, which are made of steel. The ball bearings 79 are installed on the inner wall of the square groove 75 to reduce the friction when the slider 76 slides in the square groove 75 and improve the smoothness of sliding.

When the collection box 72 moves, the spring 78 acts as a buffer and provides a reset function.

[0023] First, the connecting plate 61 is fixed to the surface of the outlet pipe 3, and a clamping block 64 is placed in the groove 62 formed therein. The clamping block 64 is slidably connected to the inner wall of the groove 62 via a fixing rod 63, which limits and guides the clamping block 64. When it is necessary to use the clamping block 64 to clamp relevant components on the outlet pipe 3, the clamping block 64 is moved to slide along the groove 62 and the fixing rod 63 to a suitable position. After the clamping block 64 is in place, the screw 66 is rotated. Since one end of the screw 66 is threaded to the surface of the connecting plate 61, and the screw 66 is slidably connected to the extension plate 65 on the surface of the clamping block 64, rotating the screw 66 will push the extension plate 65, thereby fixing the clamping block 64 to the connecting plate 61.
