Description

Technical Field

[0001] This utility model belongs to the technical field of filtration and separation, specifically relating to a latex paint filtration and purification device. Background Technology

[0002] With the increasing demands for coating quality in the building decoration industry and the increasingly stringent environmental regulations, traditional manual filtration methods can no longer meet the needs of efficient, low-consumption, and pollution-free operations. Therefore, latex paint filtration and purification devices are used. These environmentally friendly devices are specially designed for paint production and coating processes. They are mainly used to remove impurities, lumps, and bubbles from latex paint to ensure that the paint is uniform and delicate.

[0003] Currently, during the filtration process of latex paint, the surface of the filter screen or filter bag is prone to forming hidden micro-clogging due to the gradual adhesion of tiny impurities such as pigment particles and colloidal agglomerates. This clogging is difficult to detect with the naked eye or conventional pressure monitoring in the early stages, but it will lead to a slow decline in filtration efficiency, manifested as flow rate reduction and increased system energy consumption. Especially when dealing with latex paint with high solid content or high viscosity, traditional filter screens lack self-cleaning function, and their pores are easily densely clogged, which not only shortens the life of the filter material, but may also cause cross-contamination between batches. Utility Model Content

[0004] The purpose of this invention is to provide a latex paint filtration and purification device, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Latex paint filtration and purification device, including,

[0007] The purification mechanism includes a cylinder, a feed cylinder cover disposed on the top of the cylinder, a ring sleeve movably installed in the inner cavity of the cylinder, and a rack fixedly installed on the inner wall of the ring sleeve;

[0008] The cleaning mechanism includes a servo motor fixedly installed on the top of the cylinder, a shaft fixedly installed on the output end of the servo motor, and a cleaning component disposed at the end of the shaft.

[0009] As a preferred embodiment of the present invention, the cleaning mechanism further includes a bracket fixedly installed in the inner cavity of the ring sleeve for limiting the shaft, a clamping plate fixedly installed at the bottom of the ring sleeve, a downward scraper fixedly installed at the bottom of the cleaning component, and a circular protrusion fixedly installed at the bottom of the downward scraper.

[0010] As a preferred embodiment of this utility model, the cleaning component includes a grooved rod fixedly installed on the outside of the shaft, a return spring fixedly installed in the inner cavity of the grooved rod, a slider fixedly installed at the end of the return spring, a limiting block fixedly installed on the outside of the slider, a limiting guide rail fixedly installed in the inner cavity of the grooved rod, and a crossbar fixedly installed on the outside of the limiting block.

[0011] As a preferred embodiment of this utility model, the cleaning component further includes a rounded corner disposed at the end of the crossbar and a connecting plate fixedly installed at the bottom of the crossbar. The connecting plate is fixedly connected to the downward scraper, and the rounded corner is engaged with the rack.

[0012] In a preferred embodiment of this utility model, the number of cleaning components is three sets, and they are evenly distributed around the end of the shaft.

[0013] As a preferred embodiment of the present invention, the purification mechanism further includes a vibration motor fixedly installed on the outside of the cylinder, a discharge pipe fixedly installed on the outside of the cylinder, a limiting sleeve fixedly installed in the inner cavity of the cylinder, a limiting groove formed on the top of the limiting sleeve, and a filter plate movably engaged in the inner cavity of the limiting sleeve, wherein the filter plate is movably engaged in the inner cavity of the limiting groove.

[0014] In a preferred embodiment of this utility model, the ring sleeve and the limiting sleeve are movably engaged, and the filter screen is designed to be detachable and is located within the accommodating space between the ring sleeve and the limiting sleeve.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: the servo motor drives the shaft to rotate, which in turn drives three sets of evenly distributed cleaning parts to mesh with the rack and pinion on the inner wall of the ring, converting the rotation into reciprocating linear motion. This allows the downward scraper to work with the circular protrusions to continuously scrape the filter screen, effectively removing pigment particles and colloidal agglomerates. At the same time, the vibration motor works in conjunction to enhance the cleaning effect, and the return spring and limit guide rail ensure that the cleaning force is moderate and the movement is stable. This effectively solves the problem that traditional filter screens are easily clogged by pigment particles and colloidal agglomerates, significantly improving the filtration efficiency. It is suitable for the continuous production of high solids content or high viscosity latex paint. Attached Figure Description

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example

[0028] Reference Figs. 1-4 This is an embodiment of the present invention, which provides a latex paint filtration and purification device, including,

[0029] The purification mechanism 100 includes a cylinder 110, a feed cylinder cover 120 disposed on the top of the cylinder 110, a ring sleeve 130 movably installed in the inner cavity of the cylinder 110, and a rack 140 fixedly installed on the inner wall of the ring sleeve 130.

[0030] The cleaning mechanism 200 includes a servo motor 210 fixedly installed on the top of the cylinder 110, a shaft 220 fixedly installed on the output end of the servo motor 210, and a cleaning component 230 disposed at the end of the shaft 220.

[0031] Among them, the reciprocating scraping action of the automated cleaning mechanism 200 removes the deposits on the surface of the filter screen 190 in real time, reducing the increase in system back pressure and energy consumption caused by blockage.

[0032] Specifically, the cleaning mechanism 200 also includes a bracket 240 fixedly installed in the inner cavity of the ring 130 for limiting the shaft 220, a clamping plate 250 fixedly installed at the bottom of the ring 130, a downward scraper 260 fixedly installed at the bottom of the cleaning component 230, and a circular protrusion 270 fixedly installed at the bottom of the downward scraper 260.

[0033] The servo motor 210 drives the shaft 220 to rotate, which in turn drives three sets of evenly distributed cleaning parts 230 to move synchronously. The rounded corners 237 of the cleaning parts mesh with the rack 140 on the inner wall of the ring 130, converting the rotational motion into reciprocating linear motion. This causes the downward scraper 260 to continuously scrape the surface of the filter screen 190, effectively solving the problem that traditional filter screens are easily clogged by pigment particles and colloidal agglomerates, significantly improving filtration efficiency, and making it suitable for continuous production of high solids content or high viscosity latex paint.

[0034] Furthermore, the cleaning component 230 includes a grooved rod 231 fixedly installed on the outside of the shaft 220, a return spring 232 fixedly installed in the inner cavity of the grooved rod 231, a slider 233 fixedly installed at the end of the return spring 232, a limiting block 234 fixedly installed on the outside of the slider 233, a limiting guide rail 235 fixedly installed in the inner cavity of the grooved rod 231, and a crossbar 236 fixedly installed on the outside of the limiting block 234. The cleaning component 230 also includes a rounded corner 237 provided at the end of the crossbar 236, and a connecting plate 238 fixedly installed at the bottom of the crossbar 236. The connecting plate 238 is fixedly connected to the lower scraper 260, and the rounded corner 237 is meshed with the rack 140. There are three sets of cleaning components 230, which are evenly distributed around the end of the shaft 220.

[0035] The cleaning component 230 adopts an elastic connection structure of a return spring 232 and a slider 233. When encountering greater resistance, it can automatically adjust the downward pressure, which not only ensures the cleaning effect but also avoids excessive wear on the filter screen 190. The cooperation between the limiting guide rail 235 and the limiting block 234 ensures the accuracy of the movement trajectory, making the cleaning process more stable and reliable. The design of the circular protrusion 270 enhances the local pressure during scraping. Combined with the vibration effect, it can thoroughly remove micron-sized particles and significantly extend the service life of the filter screen 190.

[0036] Preferably, the purification mechanism 100 also includes a vibration motor 150 fixedly installed on the outside of the cylinder 110, a discharge pipe 160 fixedly installed on the outside of the cylinder 110, a limiting sleeve 170 fixedly installed in the inner cavity of the cylinder 110, a limiting groove 180 opened on the top of the limiting sleeve 170, and a filter screen plate 190 movably locked in the inner cavity of the limiting sleeve 170. The locking plate 250 is movably locked in the inner cavity of the limiting groove 180. The ring sleeve 130 is movably locked with the limiting sleeve 170. The filter screen plate 190 adopts a detachable design and is located in the accommodating space between the ring sleeve 130 and the limiting sleeve 170.

[0037] The vibration motor 150 works in conjunction with the cleaning mechanism 200 to ensure that impurities on the surface of the filter screen 190 are thoroughly scraped off and centrally processed through the discharge pipe 160. The snap-fit ​​structure of the ring sleeve 130 and the limiting sleeve 170 forms a sealed accommodating space, preventing impurities from splashing or re-adhering during the cleaning process, thereby ensuring the purity of different batches of latex paint and eliminating the risk of cross-contamination. The cooperative design of the filter screen 190 and the limiting sleeve 170 facilitates quick replacement or cleaning of the filter screen 190, further reducing maintenance costs and extending the service life of the filter screen 190.

[0038] During use, after the servo motor 210 starts, it drives the shaft 220 to rotate, which in turn drives the three sets of cleaning components 230 to rotate synchronously. The rounded corner 237 at the end of the crossbar 236 meshes with the rack 140 on the inner wall of the ring 130, converting the rotational motion into reciprocating linear motion. At the same time, the elastic mechanism composed of the return spring 232 and the slider 233 keeps the downward scraper 260 under appropriate pressure, which, together with the bottom circular protrusion 270, scrapes and cleans the surface of the filter screen 190. The vibration motor 150 works synchronously to generate auxiliary vibration, so that the scraped impurities are discharged through the discharge pipe 160, completing the automatic cleaning process, thereby ensuring continuous and efficient filtration of latex paint.

[0039] In summary, the servo motor 210 drives the shaft 220 to rotate, which in turn drives the three evenly distributed cleaning components 230 to mesh with the rack 140 on the inner wall of the ring sleeve 130, converting the rotation into reciprocating linear motion. This allows the downward scraper 260, in conjunction with the circular protrusions 270, to continuously scrape the filter screen 190, effectively removing pigment particles and colloidal agglomerates. At the same time, the vibration motor 150 works in conjunction to enhance the cleaning effect, while the return spring 232 and the limit guide rail 235 ensure that the cleaning force is moderate and the movement is stable. This not only significantly improves the filtration efficiency but also enables quick maintenance and avoids cross-contamination through the detachable filter screen 190 and the sealed housing design.
