Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of paint filtration devices, specifically a paint filtration device used in paint production and processing. Background Technology
[0002] In the paint production and processing, filtration is a crucial step in ensuring the quality of the final product. Its main purpose is to remove solid impurities that may have entered the paint during mixing, pumping, pipeline transportation, and storage after the paint has been mixed. If these impurities are not effectively removed, defects such as particles, pitting, and uneven gloss will appear on the paint film surface. In severe cases, they may even clog the spraying equipment, affecting the application performance and product qualification rate.
[0003] Existing paint filtration devices, such as the one disclosed in CN215026391U, include a lifting platform, a filter platform, and a filter plate. One side of the lifting platform has an oil tank, and the other side has a lifting support. An oil drain pipe with a valve is installed on the side wall of the oil tank. The filter platform includes a support frame and a base, connected to the support frame. The base has a first through hole, and a protrusion is provided on the inner wall of the first through hole near the support frame. The lifting platform is located on one side of the filter platform. The filter plate is... The filter plate is placed in the first through hole and rests on the boss. The filter plate is slidably connected to the boss. The filter plate is provided with a second through hole. The first through hole and the second through hole are connected. An anti-overflow groove is provided in the circumference of the second through hole. A filter screen is provided in the second through hole. When filtering paint, the paint passes through the filter component by gravity. However, for paint with high viscosity, the paint itself has poor fluidity, and impurities are easy to accumulate on the surface of the horizontally placed filter screen, which leads to a rapid reduction in the effective filtration area, causing the paint to pass through the filter screen at a slower speed or even stop, resulting in low filtration efficiency.
[0004] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0006] Each of the support frames is equipped with a spring column, and a fixing plate is installed at one end of the spring column. A filter structure is installed on the fixing plate.
[0007] The filter structure includes a filter cylinder, the lower end of the feeding pipe is located inside the filter cylinder, the lower end of the filter cylinder has a mesh structure, and multiple mounting plates are provided on the filter cylinder. The multiple mounting plates are correspondingly arranged with the multiple support frames, and the mounting plates are movably mounted on the fixed plate.
[0008] A vibration structure is installed on the inner top surface of the box cover. The vibration structure includes a motor, which is mounted on the box cover. The drive end of the motor is movably inserted into the stabilizing frame. An eccentric wheel is installed on the drive end of the motor, and the eccentric wheel is movably attached to the fixed plate.
[0009] Preferably, the filter cartridge is a hollow columnar structure with an open top, and the bottom of the filter cartridge is a hemispherical structure.

[0013] Preferably, the outer wall of the filter box is provided with multiple support feet.
[0014] Beneficial effects
[0015] This utility model provides a paint filtration device for paint production and processing. Compared with the prior art, it has the following advantages: During the filtration process, the eccentric wheel continuously strikes the fixed plate to generate vibration, which is transmitted to the filter cylinder through the spring column. This prevents impurities from adhering to the mesh part of the filter cylinder, reduces the clogging speed of the filter cylinder, and improves the filtration efficiency and throughput. Even when processing high-viscosity paint or paint with high impurity content, it can maintain a high filtration throughput, extend the continuous working time, reduce the frequency of downtime for filter cylinder maintenance, and improve production efficiency.

[0020] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] Example: Those skilled in the art shall connect all electrical components and their compatible power supplies in this case with wires, and select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence shall refer to the working principle described below, in which the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.
[0022] Please see Figure 1-3 A paint filtration device for paint production and processing includes a filter box 1, a discharge valve 17 inserted at the lower end of the filter box 1, a box cover 2 connected to the upper flange of the filter box 1, a feeding pipe 3 installed on the box cover 2, a flow regulating valve 4 installed at one end of the feeding pipe 3, and multiple support frames 5 installed on the inner wall of the filter box 1.
[0023] It should be noted that the device is placed in the paint production workshop and connected to a power source. The flow regulating valve 4 is connected to the paint delivery system after the paint has been mixed. The flow rate of the paint entering the feeding pipe 3 is regulated by the flow regulating valve 4.
[0024] Specifically, each support frame 5 is equipped with a spring column 6, a fixing plate 7 is installed at one end of the spring column 6, and a filter structure is installed on the fixing plate 7;
[0025] Specifically, the filter structure includes a filter cylinder 8, with the lower end of the feed pipe 3 located inside the filter cylinder 8. The lower end of the filter cylinder 8 has a mesh structure, and multiple mounting plates 9 are provided on the filter cylinder 8. The multiple mounting plates 9 are correspondingly arranged with multiple support frames 5, and the mounting plates 9 are movably mounted on the fixed plate 7. Preferably, the filter cylinder 8 is a hollow columnar structure with an open top, and the bottom of the filter cylinder 8 has a hemispherical structure.
[0026] It should be noted that the filter cylinder 8 is installed in the filter box 1 through the connection between the mounting plate 9 and the fixing plate 7. The paint is added into the filter cylinder 8 from the feeding pipe 3. When passing through the mesh structure at the lower end of the filter cylinder 8, new impurities may be introduced due to stirring, pumping or pipeline residue after the paint is filtered and mixed, so as to ensure the quality of paint filling.
[0027] Specifically, a vibration structure is installed on the inner top surface of the box cover 2. The vibration structure includes a motor 11, which is mounted on the box cover 2. The drive end of the motor 11 is movably inserted into the stabilizing frame 10. An eccentric wheel 12 is installed on the drive end of the motor 11, and the eccentric wheel 12 is movably attached to the fixed plate 7.
[0028] It should be noted that during filtration, the motor 11 operates, driving the eccentric wheel 12 to rotate, causing the eccentric wheel 12 to strike the fixed plate 7. Under the action of the spring column 6, the filter screen vibrates, preventing impurities from clogging the filter screen, improving filtration efficiency and throughput, extending continuous working time, reducing the frequency of downtime maintenance of the filter cylinder 8, and improving production efficiency. It is especially suitable for filtering high-viscosity paint. The hemispherical bottom of the filter cylinder 8 helps impurities settle and concentrate towards the center. When the paint viscosity is high, the paint flow rate is reduced by the flow regulating valve 4 to prevent paint from accumulating in the filter cylinder 8 and overflowing directly from the top of the filter cylinder 8 without filtration. Conversely, the flow rate is increased to ensure the filtration speed of the paint.
[0029] As a preferred and further option, bolts 13 are movably inserted into the fixing plate 7 and the mounting plate 9, and nuts 14 are movably fitted onto the bolts 13 via threads. Bolts 13 and nuts 14 are used for the detachable connection between the fixing plate 7 and the mounting plate 9, making the entire filter structure replaceable. The space between two adjacent mounting plates 9 is used for workers to assemble and disassemble bolts 13 and nuts 14.
[0030] As a preferred and further option, a stabilizing bracket 10 is installed between the motor 11 and the cover 2 for connecting the motor 11 and the cover 2.
[0031] As a preferred and further option, a control panel 15 is installed on the outer wall of the filter box 1. The control panel 15 has a built-in microcontroller that can be programmed with software. By writing the control program, the device can be controlled. Since this is existing technology, it will not be described in detail here.
[0032] As a preferred and further option, the outer wall of the filter box 1 is provided with a plurality of legs 16 for supporting the device.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
