Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a varnish filtering device. Background Art

[0002] Varnish is a coating composed mainly of resin as the film-forming substance plus a solvent. Since both the coating and the film are transparent, it is also called transparent coating. When applied to the surface of an object and dried, it forms a smooth film, showing the original texture of the object surface. Varnish can be used for the coating of furniture, floors, doors and windows, and automobiles. It can also be added with pigments to make enamel paints, or added with dyes to make colored varnishes. It is also used to manufacture enamel electrical appliances, and can also be used to fix sketch manuscripts, gouache manuscripts, etc., playing a certain anti-oxidation role and prolonging the preservation time of the manuscripts.

[0003] In the prior art, a varnish filtering device (publication number: CN211585443U) although uses multiple funnels, enabling the operator to have enough time to react during the process of pouring varnish into the funnels and avoiding the overflow of varnish from the funnels. However, the material filtration process in this device relies solely on its own weight to flow downward, and the filtration efficiency is still relatively low. Therefore, it is urgent to design a varnish filtering device that facilitates the acceleration of material flow. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect that in the prior art, the filtration process relies solely on its own weight to flow downward and the filtration efficiency is still relatively low, and to propose a varnish filtering device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A varnish filtering device includes a filtering cylinder. Inside the filtering cylinder, a first filter plate and a second filter plate are detachably and fixedly installed from top to bottom. A sleeve is fixedly installed at the bottom of the first filter plate. The bottom of the sleeve is of an open structure. A slider is slidably installed inside the sleeve. An impact hammer is fixedly installed at the bottom of the slider. A reciprocating lead screw is rotatably installed at the top inside the sleeve. A threaded groove adapted to the reciprocating lead screw is opened at the top of the slider. The slider is threadedly connected to the reciprocating lead screw through the threaded groove. A stirring mechanism is provided inside the filtering cylinder.

[0007] As a further technical scheme of the utility model, the filtering aperture of the first filter plate is larger than that of the second filter plate. A notch for avoiding the stirring mechanism is opened at the bottom of the impact hammer.

[0008] As a further technical solution of the present utility model, the stirring structure includes a material distributing plate and a stirring frame. One end of the bottom of the material distributing plate is rotatably installed in the middle of the top of the first filter plate. One end of the top of the material distributing plate is rotatably installed on the inner top of the filter cylinder. The rotation center of the material distributing plate is fixedly installed with the top end of the reciprocating lead screw through a coupling.

[0009] As a further technical solution of the present utility model, a connecting shaft is fixedly installed at the bottom end of the reciprocating lead screw. A through hole adapted to the connecting shaft is opened at the bottom of the slider. The bottom end of the connecting shaft passes through the through hole. A connecting rod is fixedly installed at the bottom end of the connecting shaft. The stirring frame is fixedly installed on the top of the connecting rod. A collar is fixedly installed on the top of the stirring frame. The collar is rotatably sleeved on the outer surface of the sleeve.

[0010] As a further technical solution of the present utility model, a scraping strip is fixedly installed on one side of the stirring frame. One side of the scraping strip abuts against the inner wall of the filter cylinder.

[0011] As a further technical solution of the present utility model, a servo motor is fixedly installed on the top of the filter cylinder. The output end of the servo motor is fixedly installed with the rotation center of the top of the material distributing plate. A feed inlet is opened on one side of the filter cylinder near the top end.

At the same time, the stirring mechanism stirs the materials on the surfaces of the first filter plate and the second filter plate respectively, preventing them from accumulating in one place and causing low filtration efficiency. Through stirring, the materials can be evenly distributed in the filter cylinder, improving the filtration efficiency of the equipment for clear varnish. Description of the Drawings

[0022] Please refer to the attached Figure 1 - Attached Figure 4, a varnish filtering device, including a filtering cylinder 1. Inside the filtering cylinder 1, a first filter plate 3 and a second filter plate 4 are detachably and fixedly installed from top to bottom. At the bottom of the first filter plate 3, a sleeve 6 is fixedly installed. The bottom of the sleeve 6 is of an open structure. Inside the sleeve 6, a slider 12 is slidably installed. At the bottom of the slider 12, an impact hammer 13 is fixedly installed. At the top inside the sleeve 6, a reciprocating lead screw 7 is rotatably installed. At the top of the slider 12, a thread groove adapted to the reciprocating lead screw 7 is opened. The slider 12 is threadedly connected to the reciprocating lead screw 7 through the thread groove. Inside the filtering cylinder 1, a stirring mechanism is provided. Through the setting of this device, during the rotation of the reciprocating lead screw 7, the slider 12 slides up and down inside the sleeve 6, thereby driving the impact hammer 13 to intermittently collide with the second filter plate 4, accelerating the varnish passing through the second filter plate 4 during secondary filtration, and avoiding the stagnation of the varnish flow due to its small pore size. At the same time, the stirring mechanism stirs the materials on the surfaces of the first filter plate 3 and the second filter plate 4 respectively, preventing them from accumulating in one place and causing low filtration efficiency. Through stirring, the materials can be evenly distributed inside the filtering cylinder 1, improving the filtration efficiency of the device for varnish.

[0023] Please refer to the attached Figure 2 - attached Figure 4 , in a preferred embodiment, the filtration pore size of the first filter plate 3 is larger than that of the second filter plate 4. At the bottom of the impact hammer 13, a notch for avoiding the stirring mechanism is opened. The stirring structure includes a material distributing plate 5 and a stirring frame 8. One end of the bottom of the material distributing plate 5 is rotatably installed in the middle of the top of the first filter plate 3. One end of the top of the material distributing plate 5 is rotatably installed with the top inside the filtering cylinder 1. The rotation center of the material distributing plate 5 is fixedly installed with the top end of the reciprocating lead screw 7 through a coupling. At the bottom end of the reciprocating lead screw 7, a connecting shaft 11 is fixedly installed. At the bottom of the slider 12, a through hole adapted to the connecting shaft 11 is opened. The bottom end of the connecting shaft 11 passes through the through hole. At the bottom end of the connecting shaft 11, a connecting rod 10 is fixedly installed. The stirring frame 8 is fixedly installed on the top of the connecting rod 10. At the top of the stirring frame 8, a collar 14 is fixedly installed. The collar 14 is rotatably sleeved on the outer surface of the sleeve 6. By setting two filter plates with different filtration pore sizes, the varnish can be filtered roughly and then finely twice, avoiding the accumulation of materials and affecting the smoothness of their passing through the filter plates. By setting the material distributing plate 5, the just-added materials can be evenly distributed on the surface of the first filter plate 3 for the first filtration, and then the filtered varnish is finely filtered on the second filter plate 4 for the second time, improving the filtration effect of the device for varnish.

[0024] Please refer to the attached Figure 3 and attached Figure 4, in a preferred embodiment, a scraping strip 9 is fixedly installed on one side of the stirring frame 8. One side of the scraping strip 9 abuts against the inner wall of the filter cylinder 1. A servo motor 15 is fixedly installed on the top of the filter cylinder 1. The output end of the servo motor 15 is fixedly installed at the rotation center of the top of the material distributing plate 5. An inlet 2 is formed on one side of the filter cylinder 1 near the top end. By arranging the stirring frame 8, the materials on the second filter plate 4 can be stirred up, facilitating the materials to pass through the second filter screen 4 faster to complete the filtration. At the same time, the residual varnish on the inner wall of the filter cylinder 1 can be scraped off by the scraping strip 9, avoiding material residue and improving the sufficiency of the equipment for filtering varnish.

[0025] Working principle: During use, varnish is continuously poured into the filter cylinder 1 through the inlet 2. The servo motor 15 is started to drive the material distributing plate 5 to rotate, thereby evenly pushing the varnish accumulated on the surface of the first filter plate 3, facilitating the faster completion of the first filtration. Then the materials fall on the top of the second filter plate 4 for the second fine filtration, improving the purity of the materials after filtration. During the second filtration process, the material distributing plate 5 drives the reciprocating lead screw 7 to rotate. The reciprocating lead screw 7 drives the slider 12 to slide up and down in the sleeve 6, driving the impact hammer 13 to intermittently collide with the second filter plate 4, causing it to vibrate and accelerating the downward flow of the varnish on its surface for filtration. The reciprocating lead screw 7 drives the stirring frame 8 to rotate through the connecting shaft 11 and the connecting rod 10, stirring the materials so that they can be more evenly distributed on the top of the second filter plate 4, facilitating faster flow and filtration. While the stirring frame 8 rotates, the residual varnish on the inner wall of the filter cylinder 1 is scraped off by the scraping strip 9, avoiding material waste.

[0026] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
