Description

Technical Field

[0001] This utility model relates to the field of water-based environmentally friendly coating production technology, specifically a purification device for water-based environmentally friendly coating production. Background Technology

[0002] In the production process of water-based environmentally friendly coatings, various impurities are often mixed in the coatings, such as insufficiently dispersed pigment particles and gel particles generated during polymerization. If these impurities are not removed in time, they will seriously affect the quality of the coatings, such as causing problems such as a grainy texture, reduced gloss, and reduced adhesion. Impurity removal equipment is needed in the impurity removal process.

[0003] Traditional impurity removal devices for water-based environmentally friendly coatings production typically employ simple filter screens. In these devices, the filter screen is fixedly installed inside the filter container, and the coating passes through the screen by gravity or pressure to remove impurities. However, this method has several drawbacks. First, during long-term use, impurities easily accumulate on the filter screen, clogging the pores and causing a sharp decline in filtration efficiency. For example, larger particles or sticky impurities may adhere to the filter screen, hindering the normal passage of coatings, reducing production efficiency, and even requiring frequent shutdowns to clean the filter screen. Second, cleaning clogged filter screens is often difficult, often requiring manual disassembly and cleaning with brushes or other tools. This is not only cumbersome but also consumes a lot of manpower and time, affecting production progress. Third, due to the lack of effective auxiliary cleaning mechanisms, it is impossible to clean the filter screen in real time during device operation, leading to increasingly serious impurity accumulation problems and making it difficult to guarantee continuous and efficient impurity removal for the coatings. Therefore, we propose an impurity removal device for water-based environmentally friendly coatings production. Utility Model Content

[0004] The purpose of this utility model is to provide a purification device for the production of water-based environmentally friendly coatings, to solve the problems mentioned in the background art regarding traditional purification devices for the production of water-based environmentally friendly coatings. These devices typically employ a simple filter screen filtration method, in which the filter screen is fixedly installed inside the filter container, and the coating relies on gravity or pressure to pass through the filter screen for purification. However, this method has many drawbacks. First, during long-term use, impurities easily accumulate on the filter screen, clogging the filter screen pores and causing a sharp decline in filtration efficiency. For example, some larger particles or sticky impurities will adhere to the filter screen, hindering the normal passage of the coating, reducing production efficiency, and even requiring frequent shutdowns to clean the filter screen. Second, cleaning a clogged filter screen is often difficult, and in most cases, it requires manual disassembly of the filter screen and cleaning with tools such as brushes. This is not only cumbersome but also consumes a lot of manpower and time, affecting production progress. Third, due to the lack of an effective auxiliary cleaning mechanism, it is impossible to clean the filter screen in real time during device operation, leading to increasingly serious impurity accumulation problems and making it difficult to ensure continuous and efficient purification of the coating.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model enables the filtration of environmentally friendly coating raw materials through the arrangement of a base plate, a working plate, several support columns, several springs, a filter cylinder, a mounting frame, a filter screen, a feeding funnel, a discharge pipe, and a vibrating motor. The cleaning mechanism, with its lifting motor, rotating column, screw, lifting rod, guide block, and guide groove, allows the brush rod to move up and down within the filter cylinder, enabling thorough cleaning of different parts of the filter screen. Simultaneously, the cleaning motor drives the cleaning roller and brush rod to rotate, causing the brush bristles to scrub the filter screen, effectively removing impurities adhering to it and preventing clogging of the filter screen pores. This ensures the filtration efficiency of the filter screen and, consequently, guarantees the highly efficient removal of impurities from water-based environmentally friendly coatings.

[0017] 2. This utility model achieves the following by setting the bottom of the filter cylinder with a concave structure from all sides to the center and setting manual valves on both the unloading pipe and the feed funnel pipe. This allows the filtered paint to be discharged smoothly through the unloading pipe during the impurity removal process. When it is necessary to clean the inside of the filter cylinder, the manual valves can be closed to prevent paint leakage. At the same time, the sealing rings set at the contact parts of the filter cylinder with the feed funnel, the unloading pipe, and the cleaning roller and the filter cylinder slot effectively prevent paint leakage, ensure the airtightness of the device, and avoid paint waste and environmental pollution.

[0018] 3. This utility model, through the setting of the bottom support column, spring, and vibration motor of the working plate, realizes that during the impurity removal process, the vibration motor drives the working plate and filter cylinder to vibrate, so that the coating can be more evenly distributed on the filter screen in the filter cylinder, improving filtration efficiency. At the same time, the support column and spring play a role in buffering and shock absorption, reducing the impact of vibration on the base plate and the surrounding environment. In addition, the anti-slip plate and anti-slip texture at the bottom of the base plate increases the friction between the device and the placement surface, ensuring the stability of the device during operation. The setting of the motor box and protective box in the cleaning mechanism protects the lifting motor and cleaning motor, reduces the corrosion of the motor by dust, water vapor, etc., extends the service life of the motor, and thus improves the stability and reliability of the entire cleaning mechanism and impurity removal device.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-10This utility model provides a technical solution: a purification device for the production of water-based environmentally friendly coatings, including a base plate 1, a working plate 2 directly above the base plate 1, several support columns 3 fixed at the bottom of the working plate 2, springs 4 installed between the support columns 3 and the base plate 1, a vibration motor 9 installed on the top surface of the working plate 2, a filter cylinder 5 embedded on the top surface of the working plate 2, a feed funnel 10 connected to the inner cavity of the filter cylinder 5 fixed on the top surface of the filter cylinder 5, a discharge pipe 11 connected to the inner cavity of the filter cylinder 5 fixed at the bottom end of the filter cylinder 5, manual valves 12 installed on the outer walls of both the discharge pipe 11 and the feed funnel 10, an installation frame 6 installed near the middle position inside the filter cylinder 5, and a filter screen 7 installed on the inner circumference of the installation frame 6, and further including:

[0033] Cleaning mechanism 8, installed on the top surface of work plate 2, is used to clean the surface of filter screen 7. Cleaning mechanism 8 includes an L-shaped vertical plate 81 fixed to the right end of the top surface of work plate 2, a rotating column 82 rotatably connected to the horizontal end of vertical plate 81, a rotating roller 83 rotatably connected to the top surface of work plate 2, a screw 84 coaxially fixed between rotating roller 83 and rotating column 82, a lifting motor 87 installed on the top surface of the horizontal end of vertical plate 81 with its output shaft coaxially connected to rotating column 82, and a screw 84 slidably connected to the vertical end of vertical plate 81. The filter cylinder 5 includes a lifting rod 85 threaded to the screw 84 on the left side surface of the plate end, a mounting plate 89 fixed to the left side surface of the lifting rod 85, a brush rod 812 located inside the filter cylinder 5 near the top, a fixing plate 811 fixed at the middle position of the top surface of the brush rod 812, several brush bristles 813 fixed to the bottom surface of the brush rod 812 for brushing the filter screen 7, and a cleaning roller 810 coaxially fixed to the top surface of the fixing plate 811 and slidably inserted into the filter cylinder 5. The cleaning roller 810 extends above the filter cylinder 5 and... A cleaning motor 814, with its output shaft coaxially connected to the cleaning roller 810, is rotatably connected to the mounting plate 89 and mounted on the top surface of the mounting plate 89. Through the arrangement of the base plate 1, working plate 2, several support columns 3, several springs 4, filter cylinder 5, mounting frame 6, filter screen 7, feed funnel 10, discharge pipe 11, and vibration motor 9, the environmentally friendly coating raw materials can be filtered. Through the coordinated arrangement of the lifting motor 87, rotating column 82, screw 84, lifting rod 85, and guide block 86 and guide groove in the cleaning mechanism 8, the brush rod 812 can move up and down within the filter cylinder 5, achieving thorough cleaning of different positions on the filter screen 7. Simultaneously, the cleaning motor 814 drives the cleaning roller 810 and brush rod 812 to rotate, causing the bristles 813 to brush and wash the filter screen 7, effectively removing impurities adhering to the filter screen and preventing impurities from clogging the filter screen pores, thus ensuring the filtration efficiency of the filter screen 7 and ultimately ensuring the efficient removal of impurities from the water-based environmentally friendly coatings by the entire impurity removal device.

[0034] In this embodiment, a slot is provided at the middle position of the top surface of the filter cylinder 5. The cleaning roller 810 is slidably inserted into the slot on the top surface of the filter cylinder 5. The axis of the cleaning roller 810 and the axis of the filter cylinder 5 are located on the same vertical line. The position of the brush rod 812 and the filter screen 7 are corresponding and the size is adapted. Several bristles 813 at the bottom of the brush rod 812 are arranged in a matrix. The positions of several filter screens 7 and several bristles 813 are corresponding and the size is adapted. When the cleaning roller 810 rotates, it can stably drive the brush rod 812 to clean the filter screen 7, ensuring the cleaning effect. The bristles 813 can thoroughly and effectively brush the filter screen 7 to ensure that impurities are cleaned.

[0035] In addition, the outer circumference of the mounting frame 6 is tightly fitted with the inner circumference of the filter cylinder 5, and the outer circumference of the filter screen 7 is tightly fitted with the inner circumference of the mounting frame 6, so that the mounting frame 6 and the filter screen 7 are firmly installed, and the coating will not leak from the gaps during the filtration process, thus improving the filtration effect.

[0036] Furthermore, sealing rings are provided at the contact points between the filter cylinder 5 and the feed funnel 10 and the discharge pipe 11. Sealing rings are also provided at the contact points between the cleaning roller 810 and the slot on the top surface of the filter cylinder 5. The bottom of the filter cylinder 5 has a structure that is concave from all sides to the center, and the degree of concavity is 16-26°, preferably 22° in this paper, so as to effectively ensure the sealing of the device, prevent paint leakage, avoid paint waste and environmental pollution, and at the same time enable the filtered paint to be discharged smoothly through the discharge pipe 11, thereby improving the discharge efficiency.

[0037] Specifically, a guide groove is provided on the left side surface of the vertical plate end of the upright plate 81, and a guide block 86 is fixed on the right side surface of the lifting rod 85, which is slidably connected to the guide groove on the left side surface of the vertical plate end of the upright plate 81, so that the lifting rod 85 is more stable during the up and down movement, ensuring the normal operation of the cleaning mechanism 8.

[0038] It is worth noting that the support columns 3 at the bottom of the working plate 2 are arranged in a matrix. The spring 4 is installed with a gasket 13 between the support column 3 on the same side and the base plate 1. The bottom of the base plate 1 is fixed with an anti-slip plate 14 that matches its shape. The anti-slip plate 14 has anti-slip texture on its bottom surface, which makes the working plate 2 more evenly stressed, improves the stability of the device, makes the spring 4 more stable during the buffering process, reduces wear, and extends service life. At the same time, it can also increase the friction between the device and the placement surface, ensuring that the device will not move easily during operation and improving the stability of the device.

[0039] It is worth noting that the cleaning mechanism 8 also includes a motor box 88 fixed on the top surface of the horizontal end of the vertical plate 81 and a protective box 815 fixed on the top surface of the mounting plate 89. The lifting motor 87 is located inside the motor box 88, and the cleaning motor 814 is located inside the protective box 815, which effectively protects the lifting motor 87 and the cleaning motor 814, reduces the corrosion of the motor by dust, moisture and other factors, extends the service life of the motor, and thus improves the stability and reliability of the entire cleaning mechanism 8 and the impurity removal device.

[0040] It is worth emphasizing that the cross-sectional shape of the guide groove on the left side of the vertical plate end of the upright plate 81 is convex, and the shape of the guide block 86 is convex, which matches the shape of the guide groove on the left side of the vertical plate end of the upright plate 81. This makes the guide block 86 slide more stably in the guide groove, prevents the lifting rod 85 from deviating during movement, and ensures the normal operation of the cleaning mechanism 8.

[0041] It should be added that the lifting motor 87, the cleaning motor 814, and the vibration motor 9 are all electrically connected to the external PLC via wires, and the lifting motor 87, the cleaning motor 814, and the vibration motor 9 are all electrically connected to the external power supply via wires, and the external PLC is also electrically connected to the external power supply via wires.

[0042] Finally, it should be noted that the lifting motor 87, cleaning motor 814, vibration motor 9, and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0043] In this embodiment, when it is necessary to filter and remove impurities from the environmentally friendly coating raw materials, the operator first opens the manual valve 12 on the feed funnel 10 and pours the water-based environmentally friendly coating raw materials into the filter cylinder 5 through the feed funnel 10. Then, the manual valve 12 is closed, and the raw materials flow downwards under gravity. When passing through the filter screen 7, impurities are intercepted on the filter screen 7, while the coating materials that meet the requirements pass through the filter screen 7 and enter the lower part of the filter cylinder 5, flowing out from the discharge pipe 11. During this process, the vibration motor 9 is started by the external PLC, and the vibration motor 9 drives the working plate 2. The working plate 2 vibrates under the support of several support columns 3, several springs 4, several pads 13 and anti-slip plate 14, which in turn causes the filter cylinder 5 to vibrate, helping the coating to pass through the filter screen 7 more smoothly, and also making the impurities distributed more evenly on the filter screen, thus improving the filtration effect. After filtering for a period of time, the vibration motor 9 is turned off by the external PLC, and the external raw material collection box is placed on the bottom surface of the base plate 1 and corresponding to the position of the discharge pipe 11. The raw material inside the filter cylinder 5 can be discharged by opening the manual valve 12 on the outer wall of the discharge pipe 11.

[0044] When the filter screen 7 needs cleaning, close the manual valve 12 on the outer wall of the discharge pipe 11, and start the lifting motor 87 via the external PLC. The output shaft of the lifting motor 87 drives the rotating column 82 to rotate. The rotating column 82 drives the lifting rod 85 to slide downward in the guide groove on the left side surface of the vertical plate end of the vertical plate 81 via the screw 84. The guide block 86 plays a guiding and stabilizing role. The lifting rod 85 drives the mounting plate 89 to move downward, thereby causing the cleaning roller 810, the fixed plate 811, the brush rod 812, and the brush bristles 813 to move downward. When the fixed plate 811, the brush rod 812, and the brush bristles 813 descend to a suitable height with the lifting rod 85, the lifting motor 87 is turned off via the external PLC, and the cleaning motor 87 is started via the external PLC. The cleaning motor 814 drives the cleaning roller 810 to rotate. The cleaning roller 810 drives the fixed plate 811, brush rod 812 and brush bristles 813 to rotate. The brush bristles 813 brush the surface of the filter screen 7, brushing off the impurities on the filter screen to clean the filter screen 7 and prevent impurities from clogging the filter screen 7 and affecting the filtration effect. After cleaning, the cleaning motor 814 is turned off by the external PLC. Otherwise, several brush bristles 813 can be moved to the initial position. Then, the external impurity collection box is placed on the bottom surface of the base plate 1 and corresponds to the position of the discharge pipe 11. By opening the manual valve 12 on the outer wall of the discharge pipe 11, the impurities inside the filter cylinder 5 can be discharged.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
