Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a filtering device for water-based paint production. Background Technique

[0002] Water-based paint belongs to a kind of water-based coating. Water-based paint is a coating with water as a diluent and no organic solvents. The paint film is plump, crystal clear, flexible, and has the characteristics of water resistance, wear resistance, aging resistance, yellowing resistance, fast drying, and easy use. When producing water-based paint, there may be lumps. If the lumpy water-based paint is added to the finished container, it may affect the entire paint. Therefore, a filtering device for water-based paint production is proposed.

[0003] Chinese Patent Publication No. CN218871466U discloses a filtering device for water-based paint production with an application date of December 8, 2022. In this patented technology, a driving member drives a rotating shaft to rotate, and the rotating shaft drives a conical mesh barrel to rotate through a connecting member. The centrifugal force generated during rotation can accelerate the filtration of water-based paint and improve the filtration efficiency. The fixing rod is fixedly installed on the end cover, so that the fixing rod and the brush rod remain stationary. During the rotation of the conical mesh barrel, the brush plate can clean the insoluble substances and impurities intercepted on the conical mesh barrel, preventing the mesh holes on the conical mesh barrel from being blocked. The cleaned insoluble substances or impurities fall along the inner wall of the conical mesh barrel into the collection box, avoiding the accumulation of insoluble substances or impurities on the filtering surface of the conical mesh barrel. The filtration efficiency is high, and the collection box is detachably connected to the bottom of the conical mesh barrel. After filtration, the collection box can be conveniently removed to quickly clean out the insoluble substances or impurities. However, although the above device can clean the surface of the filter screen, it will also wear the filter screen. After long-term filtration and cleaning, the filter screen will be damaged due to wear. And the above device is fixed inside the cylinder through bolts, making it inconvenient to take out the filter screen for replacement. Therefore, the inventor provides a filtering device for water-based paint production to solve the problems raised in the above background technique. Summary of the Invention

[0004] The purpose of the utility model is to provide a filtering device for water-based paint production, achieving the effect of convenient installation and disassembly of the filtering device.

Detailed implementation manner

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clearer and more understandable, the following further details this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0024] As Figure 1 、 2 shown, a filtering device for water-based paint production includes a filtration box 10. The top of the filtration box 10 is fixedly communicated with a feed pipe 11, and the bottom right side of the filtration box 10 is fixedly communicated with a discharge pipe 12. A valve 13 is installed on the discharge pipe 12; a filtration mechanism 20 is installed inside the filtration box 10.

[0025] During use, the feed pipe 11 is connected to the water-based paint discharge pipe. After the water-based paint is discharged into the filtration box 10 and filtered by the filtration mechanism 20, the treated water-based paint is discharged through the discharge pipe 12 by opening the valve 13.

[0026] Refer to Figure 2 、 3 、4, a taking groove 14 is opened on the front of the filtration box 10. The filtration mechanism 20 includes placement grooves 201 respectively opened on the left and right sides of the front of the filtration box 10. The placement grooves 201 are located directly behind the taking groove 14. Support plates 203 are respectively fixedly connected to the upper and lower sides of the opening of the placement groove 201. A sliding block 202 is arranged inside the placement groove 201. Guiding grooves 204 are respectively opened on the upper and lower sides of the sliding block 202. The sliding block 202 is slidably connected to the support plate 203 through the guiding grooves 204; the inner sides of the two sliding blocks 202 are fixedly connected with a filter plate 205 by bolts.

[0027] The above-mentioned filtering mechanism 20 is designed to be removable, facilitating the regular removal and cleaning of the filter plate 205 therein. Moreover, since the filter plate 205 is fixed to the two sliding blocks 202 by bolts, when the filter plate 205 is damaged, the bolts and the filter plate 205 can be removed and a new filter plate 205 can be replaced. After the filter plate 205 is fully installed, it is necessary to fix the position of the filter plate 205. Usually, the filtering device is fixed by bolts, but it takes a long time to loosen the bolts, making the disassembly of the filtering mechanism 20 troublesome. Therefore, a fixing mechanism 30 is proposed.

[0028] Reference Figure 5 , 6 , the fixing mechanism 30 includes a fixing groove 301 opened on the left side of the sliding block 202. The right side inside the fixing groove 301 is fixedly connected with an air pipe 302. A first piston 303 is slidably connected inside the air pipe 302. The left side of the first piston 303 is fixedly connected with a push block 304 through a connecting rod. The right side of the push block 304 is fixedly connected with a support spring 305, and the other side of the support spring 305 is fixedly connected with the surface of the air pipe 302. Slots 314 are respectively opened on the upper and lower sides of the fixing groove 301. The upper and lower sides of the right end of the air pipe 302 are respectively fixedly communicated with a communicating pipe 306. A second piston 307 is slidably connected inside the two communicating pipes 306. The outside of the second piston 307 is fixedly connected with a connecting rod 308, and the outside of the connecting rod 308 is fixedly connected with a push piece 309. The upper and lower sides inside the placement groove 201 are respectively fixedly connected with a hollow pipe 310. An extension pipe 312 is slidably connected inside the hollow pipe 310. The inner side of the extension pipe 312 is fixedly connected with a connecting spring 311, and the outside of the connecting spring 311 is fixedly connected with the hollow pipe 310. An insertion block 313 is fixedly connected inside the extension pipe 312.

[0029] Preferably, the inner surface of the insertion block 313 is designed to gradually rise from left to right; when installing the filtering mechanism 20, first place the filtering mechanism 20 at the position of the taking slot 14, and then push the filtering mechanism 20 inward, so that the sliding block 202 slides along the surface of the support plate 203. At the same time, the sliding block 202 gradually contacts the surface of the insertion block 313. When the sliding block 202 contacts the surface of the insertion block 313, the contact force causes the insertion block 313 to move outward, and the movement of the insertion block 313 drives the connection spring 311 to compress. Until the filtering mechanism 20 is completely placed into the filtering box 10, the slot 314 corresponds to the insertion block 313, so that the connection spring 311 loses the pressing force, thereby driving the insertion block 313 to move inward and insert into the slot 314, so as to fix the filtering mechanism 20. When it is necessary to take out the filtering mechanism 20, press the push block 304 inward, the push block 304 drives the first piston 303 to move inward, the air pressure drives the two second pistons 307 to move outward, and the movement of the second pistons 307 drives the two push pieces 309 to move outward through the connecting rod 308. The two push pieces 309 push the two insertion blocks 313 out of the slot 314, and then pull the filtering mechanism 20 outward to achieve the effect of taking it out.

[0030] During the above-mentioned taking-out process, it is necessary to press the two push blocks 304 separately and then pull out the filtering mechanism 20 outward. Since the two push blocks 304 are relatively far apart, it is inconvenient to press them simultaneously. Therefore, a taking-out mechanism is proposed.

[0031] Reference Figure 4 As shown in, the taking-out mechanism includes a taking block 40 fixed to the front sides of the two sliding blocks 202. The taking block 40 is inserted into the taking slot 14. A moving slot 41 is formed inside the taking block 40. A moving block 42 is arranged inside the moving slot 41. The moving blocks 42 are fixedly connected to the push blocks 304 respectively. A pushing block 43 is fixedly connected to the front side of the moving block 42. The pushing block 43 penetrates through the moving slot 41 and is located in front of the taking block 40.

[0032] Preferably, a handle 44 is fixedly connected to the front surface of the taking block 40. The handle 44 covers the pushing block 43 to prevent misunderstanding of the pushing block 43. During use, push the pushing block 43 inward. The pushing block 43 drives the moving block 42 to move inward, drives the two push blocks 304 to move inward, so that the two insertion blocks 313 are disengaged from the slot 314, and then use the other hand to pull the handle 44 outward, and the filtering mechanism 20 can be taken out, so as to achieve the effect of convenient taking-out of the filtering mechanism 20.

[0033] The working principle of the present utility model is as follows: When installing the filtering mechanism 20, first place the filtering mechanism 20 at the position of the taking slot 14, and then push the filtering mechanism 20 inward, so that the sliding block 202 slides along the surface of the support plate 203. At the same time, the sliding block 202 gradually contacts the surface of the insertion block 313. When the sliding block 202 contacts the surface of the insertion block 313, the contact force causes the insertion block 313 to move outward, and the movement of the insertion block 313 drives the connecting spring 311 to compress. Until the filtering mechanism 20 is completely placed into the filtering box 10, the positions of the insertion slot 314 and the insertion block 313 correspond, so that the connecting spring 311 loses the pressing force, thereby driving the insertion block 313 to move inward and insert into the insertion slot 314, so as to achieve the fixation of the filtering mechanism 20. When it is necessary to take out the filtering mechanism 20, press the push block 304 inward, the push block 304 drives the first piston 303 to move inward, the air pressure drives the two second pistons 307 to move outward, and the movement of the second pistons 307 drives the two pushing pieces 309 to move outward through the connecting rod 308. The two pushing pieces 309 push the two insertion blocks 313 out of the insertion slot 314, and then pull out the filtering mechanism 20 outward to achieve the effect of taking out.

[0034] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
