[0005] The purpose of this invention is to solve the problems in the existing technology of steel plate cleaning and filtration systems. In the process of operating the dirty oil pump on the side of the clean oil tank, the dirty oil pump is prone to aging and damage due to long-term operation. Furthermore, the dirty oil pump is usually complicated to install, making it inconvenient to replace and limit the protection of the dirty oil pump.

[0006] To solve the above technical problems, this utility model provides a filtration system for a steel plate washing machine, comprising: a clean oil tank and auxiliary devices. A dirty oil tank is installed on one end surface of the clean oil tank. A return oil box and a filter paper box are respectively installed at both ends of the upper surface of the dirty oil tank. The clean oil tank and the dirty oil tank are fixedly connected to the same mounting frame on one side. Several support plates are fixedly connected to the inner wall of the mounting frame. A two-stage double-cylinder filtration device is installed on one side of the mounting frame. A first-stage double-cylinder filtration device is arranged on the surface of the mounting frame near the second-stage double-cylinder filtration device. A centrifugal filtration device is arranged on the upper surface of the mounting frame. A dirty oil pump and a clean oil pump are installed on the surface of the mounting frame near the clean oil tank with the aid of support plates. An adjustment device is provided on the upper surface of the support plates corresponding to the position of the dirty oil pump. The adjustment device includes a mounting frame and a connecting plate. The mounting frame has a U-shaped cross-section. The inner wall of the mounting frame is slidably connected to the surface of the support plate with the aid of an auxiliary device. Fixed brackets are fixedly connected to both sides of the upper surface of the mounting frame. A rotating plate is rotatably connected to the inner wall of the fixed bracket. A fixed plate is rotatably connected to the upper end of the rotating plate. The fixed plate has an arc-shaped cross-section.

The sides of the two fixed plates that are close to each other abut against the surface of the fixed ring. Connecting posts are fixedly connected to both ends of the fixed plate. The four connecting posts are arranged in pairs. Connecting holes are opened at both ends of the connecting plate. The inner wall of the connecting hole is inserted into the surface of the fixed post. A rotating shaft is threadedly connected to the arc surface of the connecting post. One side of the rotating shaft abuts against the surface of the connecting plate.

[0007] The effect achieved by the above components is as follows: During the cleaning and filtration process of the entire steel plate cleaning machine, the dirty oil pump, which is installed in the mounting frame on one side of the clean oil tank with the help of the support plate, will be used for a long time. At this time, in order to facilitate the replacement and maintenance of the dirty oil pump, the mounting frame that slides on the surface of the support plate can be connected with the bottom end of the dirty oil pump. The fixed plates that rotate on both sides of the upper surface of the mounting frame can be connected with the fixed ring at the bottom end of the dirty oil pump. Then, the connecting plate is connected with the connecting columns at both ends of the fixed plate, and then the rotating shaft is used to squeeze and fix it, thereby facilitating the quick and easy replacement of the entire dirty oil pump and providing limit protection, which is convenient for long-term use.

[0008] Preferably, both ends of the inner wall of the fixing frame are fitted with coil springs, and the two ends of the coil springs are fixedly connected to the rotating plate and the fixing frame, respectively.

[0009] The effect achieved by the above components is that the torsional force generated by the coil spring can compress and limit the position of the rotating plate, preventing the rotating plate from shifting.

[0010] Preferably, the arc surface of the fixing ring is fitted with a friction sleeve, and the surface of the friction sleeve is provided with a plurality of anti-slip textures.

[0011] The effect achieved by the above components is that when the fixing ring is docked and limited with the two fixing plates, the friction sleeve can be used to increase friction, which facilitates further fixation and protection of the fixing plate position.

[0012] Preferably, positioning posts are fixedly connected to all four corners of the mounting frame, and the arc surface of the positioning posts is inserted into the bottom surface of the dirty oil pump.

[0013] The effect achieved by the above components is that the positioning post fixed on the surface of the mounting frame can be inserted and limited with the dirty oil pump, which facilitates temporary fixation of the position.

[0014] Preferably, the surface of the mounting frame is provided with an auxiliary device, which includes two limiting plates. The upper ends of the two limiting plates are fixedly connected to the bottom ends of the two sides of the mounting frame, respectively. Limiting grooves are opened on both sides of the support plate. The inner wall of the limiting groove is slidably connected to the surface of the limiting plate. The cross-section of the limiting plate is "T" shaped. A moving rod is threaded through one side of the mounting frame. A pressing plate is rotatably connected to one end of the moving rod near the support plate. A limiting rod is fixedly connected to one side of the pressing plate. The arc surface of the limiting rod slides through the side wall of the mounting frame.

[0015] The effect achieved by the above components is as follows: During the replacement and docking of the entire dirty oil pump, in order to facilitate the positional adjustment between the mounting frame and the support plate, so that the entire oil pump can be easily docked and fixed with the clean oil tank, the limiting plates on both sides of the mounting frame and the limiting grooves opened on the surface of the support plate slide together. Then, the position of the extrusion plate is moved by the moving rod and the limiting rod, so that the extrusion plate and the surface of the support plate are squeezed together, making the position of the entire mounting frame immovable, effectively and conveniently allowing the position of the dirty oil pump on the upper surface of the entire mounting frame to be adjusted.

[0016] Preferably, connecting frames are fixedly connected to both sides of the inner wall of the mounting frame, and pulleys are rotatably connected to the inner wall of the connecting frames, with the surface of the pulleys slidably connected to the side wall of the support plate.

[0017] The effect achieved by the above components is that when the position of the mounting frame is moved and adjusted, the sliding operation can be assisted by the connecting bracket and pulley on the inner wall of the mounting frame.

[0018] Preferably, an auxiliary pad is fixedly connected to the side wall surface of the support plate at the position corresponding to the extrusion plate. The auxiliary pad is a rubber pad, and the surface of the auxiliary pad abuts against the surface of the extrusion plate.

[0019] The effect achieved by the above components is that when the position of the mounting frame is pressed and fixed by the extrusion plate, the friction between the rubber auxiliary pad and the extrusion plate can be increased, which facilitates better positioning.

The fixed plates on both sides of the upper surface of the mounting frame can be connected to the fixed ring at the bottom end of the dirty oil pump. Then, the connecting plate is connected to the connecting columns at both ends of the fixed plate, and then the rotating shaft is used to squeeze and fix it. By operating the adjustment device, the entire dirty oil pump can be replaced and limited for protection, which is convenient for long-term use.
