Description

Technical Field

[0001] This utility model belongs to the technical field of impurity removal equipment, and in particular relates to an impurity removal equipment for coating raw materials. Background Technology

[0002] During the production and use of coating raw materials, various impurities often become mixed in. If these impurities are not removed in time, they will seriously affect the quality and performance of the coating. Some impurity removal equipment has the following shortcomings when in use:

[0003] 1. First, traditional impurity removal equipment is often simply designed, using only a single screen for sieving. This results in low sieving efficiency and unsatisfactory sieving effects. It is also inconvenient to replace or stack the screen frames. When processing paint raw materials containing a large number of impurities of different sizes, this type of equipment often cannot achieve fine separation, resulting in the raw materials still containing a large number of fine impurities after sieving, which is not conducive to improving the efficiency of impurity removal. Second, traditional impurity removal equipment is not convenient to replace different screens according to different raw materials, which is not conducive to improving the practicality of the equipment.

[0004] Therefore, we propose a device for removing impurities from coating raw materials. Utility Model Content

[0005] The purpose of this utility model is to address the following issues in the existing technology: First, traditional impurity removal equipment is often simply designed, using only a single screen for sieving, resulting in low sieving efficiency and unsatisfactory sieving effect. It is also inconvenient to replace or stack the screen frames. When processing paint raw materials containing a large number of impurities of different sizes, such equipment often cannot achieve fine separation, resulting in the raw materials still containing a large number of fine impurities after sieving, which is not conducive to improving the efficiency of impurity removal. Second, traditional impurity removal equipment is not convenient to replace different screens according to different raw materials, which is not conducive to improving the practicality of the equipment. Therefore, this utility model proposes a paint raw material impurity removal device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for removing impurities from coating raw materials, comprising:

[0008] A support frame is provided with a mounting frame at its upper end. A housing is fixedly connected to the middle of the upper end of the mounting frame. A first screen frame is provided at the upper end of the housing. A second screen frame is provided at the upper end of the first screen frame. An end cap is provided at the upper end of the second screen frame.

[0009] The filter assembly includes a first screen and a second screen respectively installed at the lower ends of the inside of the first screen frame and the second screen frame, for screening and removing impurities from the coating raw materials;

[0010] The installation assembly includes limiting bolts that are rotatably installed on the upper outer walls of the housing, the first screen frame, and the second screen frame, respectively. The multiple limiting bolts are respectively engaged with the first screen frame, the second screen frame, and the end cap. The upper outer walls of the multiple limiting bolts are fitted with rubber washers, and the upper outer walls of the multiple limiting bolts are threaded with limiting nuts for installing the first screen frame and the second screen frame.

[0011] The vibration assembly includes a vibration motor fixedly mounted at the lower end of the housing, used to drive the first screen frame and the second screen frame to vibrate.

[0012] In one possible design, annular support plates are fixedly connected to the lower ends of both the first and second screen frames for placing the first and second screens respectively. Annular limiting plates are provided at the upper ends of both the first and second screens for limiting their positions. Fastening bolts are provided at the front end, rear end, and both sides of the upper part of the annular limiting plate. The fastening bolts pass through the annular limiting plate, the first and second screens, and are threadedly connected to the annular support plate for limiting the installation of the first and second screens.

[0017] In this application, during use, the coating raw material is first added through the feed inlet, passes through the end cap into the second screen frame, and then passes through the second screen and the first screen in sequence. During the screening process, the vibrating motor generates vibration, which drives the shell, the first screen frame, and the second screen frame to vibrate together, causing the coating raw material to jump and roll continuously on the screen, thereby achieving effective screening. Impurities and larger particles are intercepted by the first and second screens, while the fine raw material after screening falls through the screen into the collection area below. The lower end of the first and second screen frames is provided with annular support plates to support the screens, and the screens are fixed by fastening bolts and annular limit plates to ensure the stability of screening. At the same time, different specifications of screens can be replaced to improve the practicality of the equipment. The screened impurities and raw materials are discharged from the first outlet and the second outlet, respectively, to achieve effective removal of impurities and collection of raw materials. By adjusting the limit nuts, the first screen frame, the second screen frame, and the end cap can be assembled according to actual needs. By installing the first screen frame and the end cap, different filtration and impurity removal devices can be formed.

[0018] In this utility model, the coating raw material impurity removal equipment can achieve fine separation of coating raw materials by adopting multi-layer screens and vibrating screening, effectively removing impurities and improving screening efficiency. The equipment has a simple structure, is easy to install and disassemble, and can quickly replace screens according to different coating raw materials, thus improving the practicality and flexibility of the equipment.
