[0023] The embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and cannot be understood as a limitation of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0024] Embodiment 1

[0025] Reference Figures 1-3 In this embodiment, a paint impurity removal filter device is proposed for filtering viscous paint liquid and removing solid impurities therein. The paint impurity removal filter device can include:

[0026] The liquid barrel 1 is used to hold the filtered paint liquid and forms a mounting support base. The liquid barrel 1 can be a cylindrical structure, and the filtered paint liquid can fall into the inside of the liquid barrel 1 by gravity for storage. The bottom of the liquid barrel 1 is fixedly placed on the support frame 2, which supports the liquid barrel 1 and increases the support area and operating height of the liquid barrel 1, thereby stabilizing the placement of the liquid barrel 1 and facilitating operation. The support frame 2 can include a circular placement ring and support legs. The circular placement ring can be a circular ring structure with an L-shaped cross-section, with an inner radius equal to the outer diameter of the bottom of the liquid barrel 1, so that the liquid barrel 1 can be placed in the circular placement ring. The support legs are fixedly connected to the bottom of the circular placement ring, and the number of support legs can be three, which are bent outward. The specific details are not described here. The bottom of the liquid barrel 1 can be connected with the liquid discharge pipe 3, and the paint liquid inside the liquid barrel 1 can be discharged through the liquid discharge pipe 3. Due to the relatively large viscosity of the paint liquid, the bottom of the liquid barrel 1 can be designed as a structure with a low middle and a high periphery, and the liquid discharge pipe 3 is connected at the middle position of the bottom of the liquid barrel 1, thereby facilitating the discharge of the paint liquid in the liquid barrel 1. A control valve can be provided on the liquid discharge pipe 3. Opening the control valve can discharge the paint liquid inside the liquid barrel 1. The specific structure of the control valve is a prior art, and the specific details are not described here.

[0027] The mounting frame 4 is fixedly connected to the top of the liquid tank 1 and forms a mounting support. The mounting frame 4 can be a portal structure, and the two ends of the mounting frame 4 can be fixedly mounted on the upper outer edge of the liquid tank 1 by bolts. Of course, other mounting methods are not excluded.

[0028] The filter hopper 9 is fixedly installed on the top of the liquid tank 1 and used for filtering the paint liquid. The filter hopper 9 can be a conical surface structure with a low middle and a high edge. The paint liquid on the upper part of the filter hopper 9 can flow downward along the inner wall under the action of gravity. The inclination angle of the arc surface of the filter hopper 9 can be 15-80 degrees, but other values are not excluded. The filter hopper 9 can be a rigid structure with through holes to ensure its stability and avoid deformation under the action of gravity or extrusion force. The feeding pipe 8 is rotatably arranged on the mounting frame 4. The feeding pipe 8 can be an L-shaped structure or an inverted Y-shaped structure. The feeding pipe 8 can rotate on the mounting frame 4. One end of the feeding pipe 8 is fixedly connected with the scraper 12. The bottom of the scraper 12 is in contact with the inner arc surface of the filter hopper 9. The side of the scraper 12 away from the filter hopper 9 is inclined toward the rotating direction and the lower part is bent toward the rotating direction. By being inclined toward the rotating direction, the scraper 12 rotates to press the paint liquid on the filter hopper 9, thereby increasing the filtering pressure of the paint liquid and ensuring the filtering efficiency of the paint liquid. Meanwhile, the solid can enter the space between the scraper 12 and the filter hopper 9 to be crushed, thereby facilitating dissolution. Generally, the solid particles in the paint liquid are raw materials that are not dissolved. By crushing the particles and then dissolving them in the paint liquid, the utilization rate of the raw materials can be improved. The solid particles that are not dissolved can remain on the upper surface of the filter hopper 9. Then, due to the fact that the lower part of the scraper 12 is bent toward the rotating direction, the paint liquid and the solid particles on the filter hopper 9 are subjected to a forward pushing force and an upward pushing force, thereby being conveyed forward and upward along the inclined surface of the filter hopper 9. The liquid penetrates the filter hopper 9, and the solid remains on the upper surface of the filter hopper 9. With the upward pushing force of the scraper 12, the solid is pushed out of the range of the filter hopper 9, thereby completing the solid-liquid separation. The top outer edge of the filter hopper 9 can be fixedly provided with a residue groove 14. The residue groove 14 is a circular annular groove structure. When the scraper 12 rotates to push the solid particles upward, the solid particles that cannot be dissolved or crushed are impurities that cannot be utilized. The solid particles are pushed out of the range of the filter hopper 9 by the rotating scraper 12 and then enter the interior of the residue groove 14 for collection. The end of the feeding pipe 8 is also provided with a nozzle 10 in communication. The feeding pipe 8 can be connected with a pump-in paint liquid source. The paint liquid enters the interior of the feeding pipe 8 and is finally sprayed out of the nozzle 10, thereby being sprayed on the top of the filter hopper 9. With the rotation of the feeding pipe 8, the paint liquid can be uniformly sprayed on the upper part of the filter hopper 9 and then flow downward under the action of gravity. The nozzle 10 is located on the rear side of the rotating direction of the scraper 12, thereby allowing the nozzle 10 to spray the paint liquid on the filter hopper 9 after the scraper 12 is extruded and conveyed, and allowing the paint liquid to have a time for flowing downward. In order to control the length of the paint liquid flowing downward, the speed of the rotation of the feeding pipe 8 can be controlled according to the viscosity of the paint liquid. The specific speed needs to be determined according to experience and exploration, which will not be described herein.The end of the feeding pipe 8 is also fixedly connected with a raking plate 11, which is inside the residue groove 14 and rotates with the feeding pipe 8 to clean the residue inside the residue groove 14. At least one residue discharge groove 13 is connected to the side of the residue groove 14, and the side of the raking plate 11 away from the feeding pipe 8 is inclined towards the rear of the rotation, so that the residue inside the residue groove 14 can be conveyed outward to be discharged from the residue discharge groove 13. The other end of the feeding pipe 8 is provided with a rotary sealing joint 7, which is convenient for rotatingly connecting the paint liquid source pipeline. The rotary sealing joint 7 is a prior art and will not be described here. The motor 5 is installed on the mounting frame 4 and connected with the feeding pipe 8 through the transmission member 6 to drive the feeding pipe 8 to rotate at a constant speed. The transmission member 6 can be a belt wheel combination or a gear combination structure, which will not be described here.

[0029] The motor 5 can be connected with a controller to control the motor 5 to rotate at a constant speed. The controller is a prior art and will not be described here. The paint liquid enters the inside of the feeding pipe 8, one end of the feeding pipe 8 rotates on the screen hopper 9, and the paint liquid is sprayed from the nozzle 10 to fall on the upper part of the screen hopper 9. Under the drive of the motor 5, the scraper 12 and the nozzle 10 rotate on the upper part of the screen hopper 9. The nozzle 10 rotates to uniformly spray the paint liquid on the upper part of the screen hopper 9. The paint liquid flows downward under the action of gravity, and the scraper 12 rotates to push and press the paint liquid on the screen hopper 9. The paint liquid and solid particles on the screen hopper 9 are subjected to a forward pushing force and an upward pushing force, so as to be conveyed forward and upward along the inclined surface of the screen hopper 9. The liquid penetrates through the screen hopper 9 to fall into the inside of the liquid bucket 1, and the solid is pushed upward out of the range of the screen hopper 9 by the rotating pushing force of the scraper 12, so as to complete the solid-liquid separation. The solid-liquid separation is completed by the scraper 12. Due to the viscosity of the paint liquid, the downward flowing and upward pushing working processes are realized, the filtering area of the screen hopper 9 can be fully utilized, and manual cleaning is avoided.

[0030] It should be understood that the various forms of the flow shown above can be reordered, added to, or deleted from. For example, the steps described in the present disclosure can be executed in parallel, in sequence, or in different orders, as long as the desired results of the technical solutions of the present disclosure can be achieved, and the present disclosure is not limited herein.

[0031] The above detailed description does not constitute a limitation on the protection scope of the present disclosure. Those skilled in the art should understand that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
