Description

Technical Field

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

[0002] In the ongoing pursuit of environmental protection and high performance in the coatings industry, water-based paints, with their significant advantages of using water as a diluent and having low organic solvent content, have gradually become the mainstream choice in the market. Their low-pollution characteristics during production and application align with the stringent global requirements for environmental protection and are widely used in various fields such as construction, furniture, and automobiles. However, the production process of water-based paints involves mixing various raw materials. During the stirring process, some difficult-to-dissolve impurities or incompletely dispersed raw material particles will inevitably appear. If these substances are not removed, they will seriously affect the quality of the water-based paint, leading to problems such as uneven coating, reduced adhesion, and a grainy texture after drying, greatly reducing the performance and aesthetics of the product.

[0003] The device typically contains multiple layers of filters with different pore sizes, forming a gradient filtration structure. When water-based paint flows into the filtration device from the paint inlet, it first passes through a primary filter with larger pore sizes. This filter can intercept larger impurities, such as incompletely crushed pigment particles and mixed foreign matter, thus initially purifying the water-based paint. However, filters used for extended periods need to be disassembled for cleaning, which affects filtration efficiency during production. Utility Model Content

[0004] This invention addresses the technical problem that filters used for extended periods require disassembly for cleaning, which affects filtration efficiency during production and use. It provides a filtration device for water-based paints.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filtration device for water-based paint, comprising: a filtration chamber, a slide rail connected to the upper end of the filtration chamber, a slide frame connected inside the slide rail, multiple filter plates connected inside the slide frame, a telescopic bracket connected to the slide frame, the telescopic bracket being connected to the telescopic end of a cylinder, the fixed end of the cylinder being connected to the side wall of the filtration chamber, an injection hood connected to the upper surface of the slide rail, the injection hood being fastened to the upper part of the filter plate by a sealing strip, an injection mechanism connected to the upper part of the injection hood, the filter plate being located directly above the injection mechanism, and the injection mechanism being able to discharge water-based paint into the lower part.

[0006] Preferably, the filter plate includes a plate frame connected to a slide, and multiple filter screens are detachably connected to the plate frame, with one filter screen directly opposite the lower part of the liquid injection mechanism.

[0007] Preferably, the injection mechanism includes a hose, one end of which is connected to a liquid pump, and the other end of which is connected to a rotary sealing joint. The rotary sealing joint is connected to a joint bracket, which is connected to the top wall of the injection hood. The rotary sealing joint is rotatably connected to the injection pipe, which is rotatably connected to the top wall of the injection hood. The injection pipe is connected to a power source via a belt drive. The lower end of the injection pipe is connected to a water distributor, which is located on the upper part of the filter screen.

[0008] Preferably, the water distributor includes a liquid cylinder, which is connected to and concentrically arranged with the injection pipe. Multiple water distribution pipes are evenly distributed and connected to the circumference of the liquid cylinder. A drain pipe is connected to the end of the water distribution pipe. The drain pipe is located above the edge of the filter screen. The filter screen is hemispherical and is composed of multiple filter screens with different pore sizes in a gradient decreasing combination.

[0009] Compared with the prior art, the beneficial effects of this utility model are: The water-based paint is filtered by the liquid injection mechanism in conjunction with the filter plate. When the filter plate becomes clogged, the slide is controlled to slide along the slide rail, so that the unused filter plate slides to the bottom of the liquid injection mechanism and the used filter plate slides to the outside, making cleaning very convenient. In this way, the filter plate can be replaced without stopping the machine, which greatly accelerates the filtration efficiency.

[0010] The water distributor rotates, causing the drain pipe to rotate and spray water-based paint onto the edge of the hemispherical filter screen. The water-based paint rolls down the hemispherical filter screen while filtering, so that all filtration areas of the filter screen are fully utilized. The filtered impurities are also flushed to the bottom of the hemispherical filter screen by the water-based paint, which slows down the clogging speed of the filter screen, extends the screen replacement time, and avoids the repeated sliding that accelerates the wear of the carriage.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to the connection method that allows movement through connecting parts such as hinges, pins, and short shafts.

[0015] The present invention will now be described in detail with reference to the accompanying drawings.

[0016] The following is in conjunction with the appendix Figure 1-3 This embodiment describes a filtration device for water-based paint, comprising: a filter chamber 1, a slide rail 2 connected to the upper end of the filter chamber 1, a slide frame 3 connected inside the slide rail 2, multiple filter plates 4 connected inside the slide frame 3, a telescopic bracket 5 connected to the slide frame 3, the telescopic bracket 5 being connected to the telescopic end of a cylinder 6, the fixed end of the cylinder 6 being connected to the side wall of the filter chamber 1, an injection cover 7 connected to the upper surface of the slide rail 2, the injection cover 7 being fastened to the upper part of the filter plates 4 by a sealing strip, an injection mechanism 8 connected to the upper part of the injection cover 7, the filter plates 4 being located directly above the injection mechanism 8, and the injection mechanism 8 being able to discharge water-based paint into the lower part.

[0017] In use, water-based paint is injected through the injection mechanism 8. The injection mechanism 8 works with the filter plate 4 to filter the water-based paint. The injection cover 7 is fastened to the upper part of the filter plate 4 by the sealing strip, so that the water-based paint will not leak. When the filter plate 4 is clogged, the cylinder 6 controls the slide 3 to slide along the slide rail 2, so that the unused filter plate 4 slides to the lower part of the injection mechanism 8. The used filter plate 4 slides to the outside, which is very convenient for cleaning. In this way, the filter plate 4 can be replaced without stopping the machine by sliding, which greatly accelerates the filtration efficiency.

[0018] The filter plate 4 includes a plate frame 41, which is connected to the slide 3. Multiple filter screens 42 are detachably connected to the plate frame 41, and the lower part of the liquid injection mechanism 8 is directly opposite one of the filter screens 42.

[0019] Cleaning the filter screen 42 is done by disassembling it, and cleaning the filter screen 42 is faster and more thorough.

[0020] The liquid injection mechanism 8 includes a hose 81, one end of which is connected to a liquid pump, and the other end of which is connected to a rotary sealing joint 82. The rotary sealing joint 82 is connected to a joint bracket 83, which is connected to the top wall of the liquid injection hood 7. The rotary sealing joint 82 is rotatably connected to a liquid injection pipe 84, which is rotatably connected to the top wall of the liquid injection hood 7. The liquid injection pipe 84 is connected to a power source via a belt drive 85. A water distributor 86 is connected to the lower end of the liquid injection pipe 84, which is located above the filter screen 42.

[0021] The liquid pump injects water-based paint into the injection pipe 84 through the hose 81 and the rotating sealing joint 82. The power is driven by the belt drive 85 to rotate the injection pipe 84. Under the action of the rotating sealing joint 82, the rotation of the injection pipe 84 will not affect the injection of water-based paint. The water-based paint enters the water distributor 86 through the injection pipe 84. The rotation of the water distributor 86 distributes the water-based paint evenly on the filter screen 42 for filtration, making full use of the effective filtration area of ​​the filter screen 42.

[0022] The water distributor 86 includes a liquid cylinder 861, which is connected to and concentrically arranged with the liquid injection pipe 84. Multiple water distribution pipes 862 are evenly distributed and connected to the circumference of the liquid cylinder 861. The end of the water distribution pipe 862 is connected to a drain pipe 863, which is located on the upper edge of the filter screen 42. The filter screen 42 is hemispherical and is composed of multiple filter screens with different pore sizes in a gradient decreasing combination.

[0023] The injection pipe 84 drives the liquid cylinder 861, the water distribution pipe 862, and the drain pipe 863 to rotate. The drain pipe 863 is located on the upper edge of the filter screen 42. The rotation of the drain pipe 863 sprays the water-based paint onto the edge of the hemispherical filter screen 42. The water-based paint rolls down the hemispherical filter screen 42 while filtering, so that all the filtering areas of the filter screen 42 are fully utilized. The filtered impurities are also washed by the water-based paint to the bottom of the hemispherical filter screen 42, so as to slow down the clogging speed of the filter screen, extend the screen replacement time, and avoid the reciprocating sliding that accelerates the wear of the carriage 3.
