[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0018] This utility model provides a screening device for coating raw materials, including a working box 1. Support feet 101 are evenly distributed at the bottom of the working box 1. The working box 1 has a hollow, open-top structure. A dust cover 2 is movably connected to the top of the working box 1. Positioning plates 102 are fixedly connected to both sides of the working box 1, and the dust cover 2 overlaps the positioning plates 102. A sliding frame 3 is installed inside the working box 1. Filter plates 301 are installed in three layers within the frame 3. Screen holes 302 are evenly distributed on the filter plates 301. An outlet 6 is installed at the bottom of the working box 1. The filter plates 301 are installed at an angle in the frame 3. The filter plates 301 are symmetrically distributed on both sides. The two sides of the frame 3 are fixedly connected to sliders 4. The angle of inclination of the bottom filter plate 301 is greater than that of the two layers of filter plates 301. The inner wall of the working box 1 is provided with a groove 401 that matches the slider 4. The diameter of the sieve holes 302 of the filter plate 301 gradually decreases from top to bottom. The bottom of the frame 3 is equipped with a discharge port 5. A guide plate 602 is installed below the discharge port 5. The guide plate 602 is connected to the outlet 6. The structural design of the guide plate 602 is conducive to the discharge of raw materials to the outlet 6.
[0019] In actual use, the screening device for coating raw materials first installs the frame 3 structure with multiple sets of filter plates 301 in the working box 1. During installation, the frame 3 is guided by the slider 4 sliding in the groove 401 until the entire frame 3 structure is fully inserted into the working box 1. At this point, the discharge port 5 abuts against the guide plate 602. Then, the dust cover 2 structure is manually installed at the top of the working box 1, overlapping the positioning plate 102. The coating raw materials to be screened are conveyed into the working box 1 from the feed inlet 201. The raw materials entering the working box 1 are filtered and screened by the filter plates 301 with different screen holes 302. Finally, the screened coating raw materials discharged from the outlet 6 are collected in time by the collection box 601. Relatively large particles remain in the frame 3. After one screening cycle is completed, the dust cover 2 is removed, and the frame 3 structure is manually disassembled from the working box 1. To facilitate subsequent screening, the filter plate 301 is directly installed in the frame 3. When disassembly and maintenance are required, the entire frame 3 structure can be removed from the working box 1. By installing multiple sets of filter plates 301 in the frame 3, and then installing the entire frame 3 structure in the working box 1, and finally installing the dust cover 2 structure at the open position of the working box 1, dust is prevented from being generated during the material transportation process. The filter plates 301 are arranged in multiple inclined groups in the frame 3, and the aperture of the screen holes 302 between adjacent upper and lower layers of filter plates 301 is inconsistent, gradually decreasing from top to bottom, ensuring the screening quality of the raw materials. Compared with the conventional filter plates 301, which are not easy to disassemble in the screening device, the technical solution adopted by this utility model can realize quick disassembly and assembly of the filter plates 301 in the screening device, avoiding the situation where the filter plates 301 are directly installed in the working box 1 and are not easy to disassemble. The overall structure is compact and the space layout is reasonable.
[0020] Example 1
[0021] like Figure 1-2 As shown, an auxiliary plate 501 is provided below the bottom filter plate 301, and the end of the auxiliary plate 501 is connected to the discharge port 5. A movable collection box 601 is installed below the outlet 6. A handle ring 303 is installed on the top of the frame 3, and a guide port 201 is installed on the top of the dust cover 2.
[0022] The effect achieved by the entire embodiment 1 is that, during use, an auxiliary plate 501 is provided below the filter plate 301, and the end of the auxiliary plate 501 is connected to the discharge port 5. The structural design of the auxiliary plate 501 is conducive to the falling of the raw material being screened above the auxiliary plate 501. The structural design of the guide port 201 is conducive to the raw material being screened entering the working box 1. Working principle: First, the frame structure containing multiple filter plates is installed in the working box. During installation, the frame is guided by a slider sliding in the groove until the entire frame structure is fully inserted into the working box. At this point, the discharge port abuts against the guide plate. Then, the dust cover structure is manually installed at the top of the working box, with the entire dust cover structure overlapping the positioning plate. The raw materials to be screened are fed into the working box from the feed inlet. The raw materials enter the working box and are filtered and screened by filter plates with different screen holes. Finally, the screened raw materials discharged from the outlet are collected by the collection box in time. Relatively large particles are retained in the frame. After one screening is completed, the dust cover is removed, and the frame structure is manually disassembled from the working box to facilitate subsequent screening work. The filter plates are directly installed in the frame. When disassembly and maintenance are required, the entire frame structure can be disassembled from the working box.
