Description

Technical Field

[0001] The invention relates to the field of coating, in particular to a collection device for paint thinner. Background Art

[0002] Paints are widely used in industrial production and building decoration. Paint thinners, as important auxiliary materials for adjusting paint viscosity and improving construction performance, will generate a large amount of waste liquid that needs to be recycled and treated during use.

[0003] In terms of filtration effectiveness, existing collection devices mostly utilize a single filter structure, resulting in low filtration accuracy and an inability to achieve multi-stage fine filtration. Paint thinner often contains a variety of contaminants, such as paint residue, dust, and particulate matter. A single filter cannot completely capture impurities of varying particle sizes, resulting in insufficient purity of the recovered thinner, making it impossible to directly reuse it and increasing subsequent processing costs. Regarding cleaning and maintenance, traditional filter cleaning requires frequent manual disassembly, which is not only labor-intensive and time-consuming, but also prone to thinner leakage during the disassembly process, polluting the work environment. Furthermore, manual cleaning is difficult to completely remove stubborn impurities trapped in the filter gaps, leading to serious filter clogging after long-term use, further impacting filtration efficiency and collection effectiveness. Regarding sealing and environmental performance, many collection devices lack effective sealing structures at the feed and discharge stages, allowing the thinner to volatilize easily. This not only wastes resources but also releases harmful gases, endangering the health of operators and failing to meet environmental standards. Furthermore, the collected wastewater is often mixed, making it impossible to separate the filtered clean thinner and the impure wastewater, increasing the difficulty of waste disposal and environmental risks. The ease of use of the collection bins also needs to be improved. The installation and disassembly process of traditional collection barrels is cumbersome and requires complex fixing steps, which is not conducive to rapid replacement and transportation.

[0004] To this end, a new collection device with multi-stage filtration, automatic cleaning, sealed and environmentally friendly, and chamber collection functions is proposed to improve the recovery quality and efficiency of paint thinners, reduce labor costs and environmental burdens, and adapt to the development needs of modern industrial green production.

The rubber ring 203 seals the feed path, and the filter cotton 306 absorbs harmful gases in the exhaust gas, which meets the safety and environmental protection requirements, and the feed funnel 2 makes the collection bucket 3 easy to disassemble and assemble, which is conducive to the transportation of the collection bucket 3; the upper end of the square funnel 4 is open to receive paint thinner, and the sixteen through holes on the surface are used to install bolts for locking. The filter bucket 101 is welded at the lower end to guide the liquid into the filter mechanism.

[0029] See Figure 1-6 As shown in the figure, the filtering mechanism 1 includes a filter bucket 101 welded to the lower end of the square funnel 4, a rounded frame 102 welded to the rear end of the filter bucket 101, three filter screen outer frames 103 inserted into the chute of the filter bucket 101, a filter mesh 104 adhesively mounted in the filter screen outer frame 103, a No. 1 support frame 105 welded to the rear end of the upper surface of the filter bucket 101, a No. 1 cylinder 106 welded to the No. 1 support frame 105, and a No. 1 cylinder 106 welded to the lower end of the No. 1 cylinder 106.

The output end of the No. 2 cylinder 111 is fixedly connected to the upper end of the push-pull frame 112, and the brush strip 114 fits the surface of the filter mesh 104.

[0031] Specifically, the filter bucket 101 serves as the main filtering cavity, accommodating the paint thinner and guiding it to be filtered through the multi-layer filter mesh 104; the upper end is connected to the square funnel 4 for feeding, and the lower end is connected to the collection bucket 3 through the feeding funnel 2; the rounded frame 102 is welded to the rear end of the filter bucket 101 to form an auxiliary channel for guiding clean impurities; the filter mesh outer frame 103 is inserted into the filter bucket 101 slide, fixing the filter mesh 104, and locked with the fixing plate 108 by hexagonal bolts 109 for easy disassembly and cleaning; the filter mesh 104 increases in mesh number from top to bottom, realizing three-time fine filtration, intercepting paint residue, dust and other impurities layer by layer, the No. 1 support frame 105 is welded to the top of the filter bucket 101 and reinforced by the triangular plate to support the No. 1 cylinder 106. The No. 1 cylinder 106 drives the baffle 107 to move up and down, blocking the surface of the filter mesh 104 during filtration to prevent the liquid from flowing directly down, and retracting and withdrawing the baffle during cleaning to allow the filter mesh 104 to be easily removed. Brush cleaning does not affect the flow of paint residue, dust and other impurities into the rounded frame 102; the baffle 107 is against the rear end of the filter frame 103, blocking the liquid from passing directly during filtration, forcing the diluent to flow through the filter mesh 104; the fixing plate 108 is attached to the front surface of the filter bucket 101, fixing the second support frame 110 and the push-pull mechanism; locking the fixing plate 108 and the filter bucket 101, making it easy to disassemble and maintain the filter frame 103; the second support frame 110 is connected to the filter basket 101 through the triangular plate It is reinforced on the fixed plate 108 to support the No. 2 cylinder 111; it drives the push-pull frame 112 to move up and down, driving the brush strip 114 to slide along the surface of the filter mesh 104 to remove impurities; the push-pull frame 112 is inserted into the through hole of the fixed plate 108, connecting the No. 2 cylinder 111 and the push-pull plate 113; the push-pull plate 113 fixes the brush strip 114; the brush strip 114 fits the surface of the filter mesh 104, and removes paint residue, dust and other impurities through mechanical movement to achieve automatic cleaning.

[0032] See Figure 1 and 7 As shown in the figure, the feed funnel 2 includes a circular funnel 201 welded to the lower ends of the filter bucket 101 and the rounded frame 102, a sealing sleeve 202 slidably mounted on the lower end of the circular funnel 201, and a rubber ring 203 bonded to the inner side of the sealing sleeve 202.

[0033] A crescent plate is welded and fixed on the outer side of the sealing sleeve 202 , and four annular grooves are evenly distributed on the inner side of the rubber ring 203 .

[0034] Specifically, it is welded to the filter hopper 101 and the lower end of the rounded frame 102 to guide the filtered diluent and impurities into the collection barrel 3; the sealing sleeve 202 is slidably sleeved on the lower end of the circular funnel 201, and the position is manually adjusted through the outer crescent plate to cover the barrel mouth ring 304 of the collection barrel; the inner annular groove of the rubber ring 203 fits tightly with the barrel mouth ring 304 to form a seal to prevent liquid leakage or volatilization.

[0035] See Figure 1-8 As shown in the figure, the collecting barrel 3 includes a barrel body 301 placed under the filtering mechanism 1, a partition 302 welded and installed inside the barrel body 301, a handle 303 welded and installed on the outside of the barrel body 301 near the upper end, two barrel mouth rings 304 embedded and welded in the feed through hole of the barrel body 301, an exhaust hole ring 305 embedded and welded in the exhaust through hole of the barrel body 301, and filter cotton 306 filled in the exhaust hole ring 305.

[0036] The partition 302 is located between the exhaust hole rings 305, and the interior of the barrel body 301 is divided into two cavities by the partition, and the volume ratio between the two is 3:1. The large cavity of the barrel body 301 is aligned with the lower end of the filter bucket 101, and the small cavity of the barrel body 301 is aligned with the lower end of the rounded frame 102.

[0037] The upper end of the barrel mouth ring 304 is inserted into the interior of the sealing sleeve 202 , and the upper surface of the barrel mouth ring 304 is in contact with the lower surface of the circular funnel 201 .

[0038] Specifically, the barrel body 301 contains filtered paint thinner, and the interior is divided into two cavities, large and small, by the partition 302; the partition 302 separates the cavities, the large cavity is aligned with the filter bucket 101 to receive the filtered clean thinner, and the small cavity is aligned with the rounded frame 102 to receive impurity waste liquid; the handle 303 facilitates the transportation and replacement of the collection barrel 3; the barrel mouth ring 304 is embedded in the barrel body feed port, inserted into the sealing circular sleeve 202, and fits with the bottom surface of the circular funnel 201 to ensure the feed seal; the exhaust hole ring 305 is embedded in the barrel body exhaust hole to provide a gas circulation channel, and the filter cotton 306 is filled in the exhaust hole to filter the volatile harmful gases and reduce the pollution of the working environment.

[0039] It should be noted that the present invention is a device for collecting paint thinner. When in use, during the installation of the collection barrel, the collection barrel 3 is placed under the filter mechanism 1, so that the lower end of the filter funnel 101 is aligned with the large cavity of the barrel body 301, and the lower end of the rounded frame 102 is aligned with the small cavity. The sealing sleeve 202 is slid downward, and the barrel mouth ring 304 is inserted into the sealing sleeve 202, ensuring that the upper surface of the barrel mouth ring is in contact with the lower surface of the circular funnel 201. The annular groove of the rubber ring 203 is tightly sealed with the barrel mouth ring to prevent liquid leakage.

[0040] During the process of collecting paint thinner, the paint thinner to be processed is collected through the opening at the upper end of the square funnel 4, and the liquid flows into the filtering mechanism through the filter hopper 101 at the lower end of the square funnel. The sixteen through holes on the surface of the square funnel 4 are used to install bolt fixing devices to ensure stability during feeding;

[0041] During the multi-stage filtration process, the diluent passes through the filter mesh 104 in the three-layer filter frame 103 in sequence, intercepting impurities such as paint residue and dust layer by layer. The No. 1 cylinder 106 keeps the baffle 107 downward against the rear end of the filter frame, forcing the liquid to flow through the filter mesh and avoid flowing directly from the rear end.

[0042] During the separation process of impurities and cleaning waste liquid, the filtered cleaning diluent flows into the large cavity of the collection bucket through the circular funnel 201 at the lower end of the filter bucket 101. Impurities intercepted during the filtration process adhere to the surface of the filter mesh and need to be cleaned regularly. When the cleaning program is started, the No. 1 cylinder 106 retracts the baffle 107 to expose the rear end of the filter mesh, and the No. 2 cylinder 111 drives the push-pull frame 112 and the brush bar 114 to slide up and down to brush off impurities on the surface of the filter mesh. The impurities flow into the small cavity of the collection bucket through the circular funnel at the lower end of the rounded frame 102;

[0043] During the automatic filter cleaning process, the second cylinder 111 is started regularly to remove impurities on the surface of the filter mesh 104 through the mechanical movement of the brush bar 114, reducing the frequency of manual maintenance. During the cleaning process, impurities flow into the small cavity of the collection barrel through the channel of the rounded frame 102, realizing the separate collection of the filtered and cleaned waste liquids;

[0044] During the replacement of the collection barrel, when the large chamber of the collection barrel is close to full capacity, slide the sealing sleeve 202 upward to release the seal with the barrel ring 304, remove the old barrel and replace it with a new one, and repeat the steps of installing the collection barrel. The impurities and waste liquid in the small chamber need to be handled separately to avoid environmental pollution.

[0045] During deep cleaning or replacement of the filter, if the filter mesh 104 is severely clogged, remove the hexagonal bolts 109, remove the fixing plate 108, take out the filter mesh outer frame 103 in the chute of the filter bucket 101, and manually clean or replace the filter mesh with a new one to ensure the filtering effect;

[0046] During the sealing and exhaust process, the rubber ring 203 and the sealing sleeve 202 ensure that the feed path is sealed to prevent the diluent from volatilizing. The filter cotton 306 in the collection barrel exhaust hole ring 305 needs to be replaced regularly to absorb the volatilized harmful gases, meeting safety and environmental protection requirements.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
