Description

Technical Field

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

[0002] In the paint production and processing industry, impurities mixed in with paint can seriously affect its quality and performance, such as causing uneven coating surfaces, reduced adhesion, and uneven color, thereby impacting the quality of the final product and its market competitiveness. Therefore, the impurity filtration process is crucial in the paint processing workflow.

[0003] Existing devices have some drawbacks in use. For example, some existing paint impurity filtration devices have complex structures, and the filter components are often tightly integrated with the main body of the device, making them difficult to disassemble. When it is necessary to clean or replace the filter components, a lot of time and effort are required, and even professional technicians need to use special tools to complete the operation. This not only increases the maintenance costs of enterprises but also affects production efficiency. Moreover, because the device as a whole is difficult to disassemble, impurities are easy to accumulate in the top frame and inside the filter tank, which is very inconvenient to clean. Long-term accumulation will affect the normal operation and filtration effect of the device. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Example

[0020] like Figures 1-4As shown, this utility model provides a technical solution: a paint impurity filtration device, including a filter tank 1. A support frame 101 is fixedly sleeved on the outer wall of the bottom of the filter tank 1, and the filter tank 1 is supported and fixed by the support frame 101. A discharge pipe 11 is fixedly connected to the bottom end of the filter tank 1. A filter frame 12 is threadedly sleeved on the top of the filter tank 1. A filter assembly 2 is provided inside the filter frame 12. A top frame 13 is threadedly sleeved on the outer wall of the top of the filter frame 12. A feed pipe 14 is embedded at the center of the upper end face of the top frame 13. An auxiliary assembly 3 is provided inside the top frame 13. In specific use, the paint to be filtered is injected into the top frame 13 through the feed pipe 14. Then the paint flows through the filter assembly 2. The filter assembly 2 intercepts impurities in the paint. The filtration efficiency is further improved by the cooperation of the auxiliary assembly 3 and the filter assembly 2. The filtered paint enters the filter tank 1. After filtration, the paint is discharged from the discharge pipe 11 for subsequent use.

[0021] As one implementation method in this embodiment, such as Figure 3 and Figure 4 As shown, the filter assembly 2 includes multiple mounting slots 21 arranged in a ring on the inner wall of the top frame 13. Each mounting slot 21 has a mounting block 22 inserted inside it. Multiple filter screens 23 are arranged in an array on the mounting blocks 22. In actual use, the mounting blocks 22 are inserted into the multiple mounting slots 21 arranged in a ring on the inner wall of the top frame 13. When the mounting blocks 22 are installed in place, the multiple filter screens 23 together constitute the filter assembly 2, forming a filtration barrier for paint impurities. The filter frame 12 can be disassembled as a whole, which facilitates cleaning of the filter frame 12, as well as cleaning of the top frame 13 and the filter tank 1. In actual use, handles can be fixed on the outer wall of the top frame 13 and the filter frame 12 for easy rotation and disassembly. To clean the filter screens 23, simply pull out the mounting blocks 22 to clean and replace the filter screens 23.

[0022] As one implementation method in this embodiment, such as Figure 1 and Figure 3As shown, the auxiliary component 3 includes a fixed ring 31 rotatably connected to the upper end face of the top frame 13. A handle 311 is fixedly connected to the outer wall of the fixed ring 31. Multiple support rods 32 are fixedly arranged in a ring on the upper end face of the fixed ring 31. A connecting ring 33 is fixedly connected to the bottom end of the multiple support rods 32. Multiple cleaning brushes 34 are fixedly arranged in a ring on the inner wall of the connecting ring 33. A liquid level measuring device 35 is fixedly installed on the inner top wall of the top frame 13. The liquid level measuring device 35 is electrically connected to an external controller. In actual use, when paint enters the top frame 13 through the feed pipe 14, the liquid level measuring device 35 monitors the liquid level height of the paint in the top frame 13 in real time and records the liquid level. The liquid level data is transmitted to an external controller in the form of an electrical signal. The external controller analyzes and judges the received liquid level data according to the preset liquid level threshold. If the liquid level is too high (usually when the filter screen 23 is clogged), the external controller can issue an alarm signal to remind the operator to control the feeding speed or stop feeding to prevent paint from overflowing the top frame 13. Then, by manually holding the handle 311, the fixed ring 31 is pushed to rotate. The fixed ring 31 drives the support rod 32, the connecting ring 33 and its cleaning brush 34 to rotate synchronously, thereby cleaning the surface of the filter screen 23 and preventing impurities from clogging the filter screen 23 and affecting the filtration effect.

[0023] As one implementation method in this embodiment, such as Figure 3 As shown, the upper end face of the top frame 13 has a ring array of multiple arc-shaped sliding openings 15, and multiple support rods 32 slide within the corresponding arc-shaped sliding openings 15, so that the support rods 32 can rotate synchronously during the rotation of the fixed ring 31.

[0024] Working principle: During use, the paint to be filtered is injected into the top frame 13 through the feed pipe 14. The paint then flows through the filter screen 23. When the paint enters the top frame 13 through the feed pipe 14, the liquid level measuring device 35 monitors the liquid level height of the paint in the top frame 13 in real time and transmits the liquid level data to the external controller in the form of an electrical signal. The external controller analyzes and judges the received liquid level data according to the preset liquid level threshold. If the liquid level is too high (usually when the filter screen 23 is blocked), the external controller can issue an alarm signal to remind the operator to control the feeding speed or stop feeding to prevent the paint from overflowing the top frame 13. Then, by manually holding the handle 311, the fixing ring 31 is pushed to rotate. The fixing ring 31 drives the support rod 32, the connecting ring 33 and its cleaning brush 34 to rotate synchronously, thereby cleaning the surface of the filter screen 23 and preventing impurities from clogging the filter screen 23 and affecting the filtration effect. After filtration, the paint is discharged from the discharge pipe 11 for subsequent use.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
