A mixing device for a paint filter

Abstract

This utility model provides a mixing device for a paint filter, relating to the field of paint production technology. The device includes a filter tank with an inlet and an outlet fixedly connected to its upper and lower ends, respectively. Support legs are fixed to the outer surface of the filter tank, and a filter screen is fixedly connected to its inner surface. Paint is poured into the filter tank through the inlet and falls into a mixing tank, where it accumulates. With the help of a motor and a stirring rod, the accumulated paint in the mixing tank is thoroughly stirred, restoring the paint to a uniformly dispersed state and removing larger sediment particles. Once a pressure sensor detects that the paint in the mixing tank has reached a predetermined weight, the controller opens a solenoid valve, allowing the uniformly stirred paint in the mixing tank to be fed through a discharge pipe to the filter screen for filtration, effectively preventing the filter screen from becoming clogged due to larger sediment particles in the paint.

Description

Technical Field

[0001] This utility model relates to the field of coating production technology, and in particular to a stirring device for a coating filter machine. Background Technology

[0002] A paint filter is a multi-purpose filtration device used for processing and purifying paint. It uses physical filtration methods, employing filter media such as filter cartridges or filter bags to trap particulate matter in the paint, ensuring its purity. Paint filters typically feature novel structures, small size, simple and flexible operation, high efficiency, closed-loop operation, and strong adaptability.

[0003] However, in the existing technology, in order to ensure the production quality of the paint, the paint is generally filtered to remove impurities. However, some existing filtration devices lack a stirring mechanism for the paint when filtering. If the paint settles in the tank before filtration, the larger particles formed by the sediment will clog the pores of the filter screen during the filtration process, resulting in poor filtration effect. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies: some existing filtration devices lack a stirring mechanism for the coating when filtering it. If the coating settles in the container before filtration, the larger particles formed by the sediment will clog the pores of the filter screen during the filtration process, resulting in a poor filtration effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mixing device for a coating filter, comprising a filter tank, wherein an inlet is fixedly connected to the upper end and an outlet is fixedly connected to the lower end of the filter tank, and a support leg is fixedly fixed to the outer surface of the filter tank; a filter screen is fixedly connected to the inner surface of the filter tank, and a fixing rod is fixedly fixed to the top of the inner surface of the filter tank; a support ring is fixedly fixed to the lower end of the fixing rod; an overlapping ring is hung on the surface of the support ring, and a mixing tank is fixedly fixed to one end of the overlapping ring; a pressure sensor is fixedly connected to the surface of the support ring at the lower end of the overlapping ring; a controller is fixedly fixed to the outer surface of the filter tank, and a motor is fixedly fixed to the top of the filter tank; a mixing rod is fixedly connected to the output end of the motor, and the mixing rod is connected to the filter tank through the filter tank; a discharge pipe is fixedly fixedly connected to the lower surface of the mixing tank, and a solenoid valve is fixedly installed on the outer surface of the discharge pipe.

[0006] In a preferred embodiment, a funnel is fixedly connected to the upper end of the feed inlet.

[0007] In a preferred embodiment, a protective cover is fixedly connected to the top surface of the filter tank near the motor mounting location.

[0008] In one preferred embodiment, several pressure sensors are arranged at equal intervals around the support ring.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] In this invention, after the paint is poured into the filter tank through the inlet, it first falls into the mixing tank and accumulates. At this time, with the help of the motor and the stirring rod, the paint accumulated in the mixing tank is fully stirred, so that the paint is restored to a uniformly dispersed state and larger sediment particles are removed. After the pressure sensor detects that the paint accumulated in the mixing tank has reached a predetermined weight, the controller will open the solenoid valve, allowing the uniformly stirred paint in the mixing tank to be sent to the filter screen through the discharge pipe for filtration, effectively avoiding the filter screen from being clogged by larger sediment particles in the paint.

[0017] 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.

[0018] Example 1

[0019] like Figure 1-4 As shown, this utility model provides a technical solution: a coating filter stirring device, including a filter tank 1. The upper and lower ends of the filter tank 1 are respectively connected to an inlet 2 and an outlet 3. The coating to be filtered is poured into the filter tank 1 through the inlet 2 for filtration. The filtered coating flows out through the outlet 3. Support legs 4 are fixed to the outer surface of the filter tank 1, providing overall support. A filter screen 6 is fixed to the inner surface of the filter tank 1, filtering the coating. A fixing rod 7 is fixed to the top of the inner surface of the filter tank 1, with a support at its lower end. Ring 8, with a connecting ring 9 attached to its surface, and a mixing tank 10 fixed to one end of the connecting ring 9. Through the combined force of the fixing rod 7, the supporting ring 8, and the connecting ring 9, the mixing tank 10 is suspended at the top of the filter tank 1. The coating material introduced into the filter tank 1 from the inlet 2 will first accumulate inside the mixing tank 10. A pressure sensor 11 is fixedly connected to the surface of the supporting ring 8 at the lower end of the connecting ring 9. A controller 12 is fixed to the outer surface of the filter tank 1. The pressure sensor 11 senses the weight of the mixing tank 10 and transmits the data to the controller 12 in real time for analysis. The controller 12 then sets the stirring parameters. The controller 12 receives the weight of the paint when the mixing tank 10 is almost full and promptly opens the solenoid valve 17 to ensure that the evenly mixed paint in the mixing tank 10 is promptly sent to the filter screen 6 below for filtration. A motor 13 is fixed to the top of the filter tank 1, and a stirring rod 15 is fixedly connected to the output end of the motor 13, with the stirring rod 15 penetrating and connected to the filter tank 1. A discharge pipe 16 is fixedly fixed to the lower surface of the mixing tank 10, and a solenoid valve 17 is fixedly installed on the outer surface of the discharge pipe 16. When the paint needs filtration, paint of the same weight as set in the controller 12 is poured into the inlet 2. The paint is poured in through the inlet 2. After being poured into the filter tank 1, the paint first falls into the mixing tank 10 and accumulates. At the same time as the paint is poured in, the motor 13 is started, which drives the stirring rod 15 to rotate and fully stir the paint accumulated in the mixing tank 10, so that the paint is restored to a uniformly dispersed state and larger sediment particles are removed. When the pressure sensor 11 senses that the paint accumulated in the mixing tank 10 has reached the predetermined weight, the controller 12 will open the solenoid valve 17, allowing the uniformly stirred paint in the mixing tank 10 to be sent to the filter screen 6 for filtration through the feed pipe 16. The filtered paint in the filter screen 6 will flow out from the discharge port 3. When no paint flows out of the discharge port 3, the next batch of paint can be filtered.

[0020] Example 2

[0021] like Figure 1-4As shown, a funnel 5 is fixedly connected to the upper end of the feed inlet 2. With the help of the funnel 5, the upper opening of the feed inlet 2 is enlarged, so that when the paint is poured into the feed inlet 2, the paint will spill out. A protective cover 14 is fixedly connected to the top surface of the filter tank 1 near the installation position of the motor 13. The protective cover 14 protects the motor 13 and prevents paint from accidentally spilling onto the motor 13 and causing damage. Several pressure sensors 11 are arranged equidistantly around the support ring 8. By evenly distributing the pressure sensors 11 on the support ring 8, the accuracy of sensing the weight of the mixing tank 10 is effectively improved.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
