It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0020] 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.
[0021] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution: a polyoxymethylene granule screening device, including a screening component 1, a disassembly component 2 and an adsorption component 3. The screening component 1 includes a screening box 101, a screen 103 inside the screening box 101, and a vibration motor 102 installed on the side of the screening box 101. The disassembly component 2 includes a limiting frame 201 and an insert block 205. The insert block 205 is located at the bottom of the screen 103. A fixing plate 206 is symmetrically installed on the inner side of the screening box 101. A fixing frame 203 is symmetrically installed on the screening box 101. A limiting plate 204 is movably installed inside the fixing frame 203. An installation groove is opened on the top of the screening box 101. The limiting frame 201 is movably installed inside the installation groove. A pull ring 202 is installed on the top of the limiting frame 201. Multiple sealing baffles 104 are symmetrically installed on both sides of the screening box 101. A sliding groove 105 is movably installed inside the sealing baffle 104.
[0022] In this embodiment, a screen 103 is provided inside the screening box 101. The screen 103 has different diameter filter holes in each layer, which is beneficial for screening polyoxymethylene granules. The movable chute 105 moves inside the sealing baffle 104, which helps to discharge the screened polyoxymethylene granules. The vibration motor 102 works to achieve vibration screening. By placing the screen 103 inside the screening box 101, the insert block 205 is inserted into the fixed plate 206, which is beneficial for screening... The screen component 103 is installed, and then the limiting frame 201 is inserted into the installation slot, which helps to limit the screen component 103. Finally, the moving limiting plate 204 moves inside the fixed frame 203, causing the limiting plate 204 to apply a certain pressure to the limiting frame 201, which helps to limit the limiting frame 201. This eliminates the need for frequent installation and removal of bolts, shortens equipment downtime, and improves work efficiency. At the same time, it facilitates the maintenance and replacement of the screen component 103, improving maintenance efficiency.
[0023] Example 2: As Figures 1-4As shown, the adsorption assembly 3 includes an adsorption cover 301, one end of which is connected to a connecting pipe 302, and one end of the connecting pipe 302 is fitted with an adsorption box 303. A suction fan 305 is installed inside the adsorption box 303, and a filter element 304 is installed inside the adsorption box 303. A protective frame 306 is provided on the outside of the suction fan 305. Slide rails 307 are symmetrically installed on the side of the adsorption box 303, and a sealed box door 308 is movably installed inside the slide rails 307.
[0024] In this embodiment, the suction fan 305 generates suction, which causes the adsorption hood 301 to adsorb the dust generated by the vibration screening, reducing the amount of dust in the air and thus lowering the dust concentration, protecting the respiratory health of the operators. The filter element 304 helps prevent dust from entering the suction fan 305. The movable sealing door 308 moves inside the slide rail 307, which facilitates the cleaning of the suctioned dust.
[0025] The working principle of this embodiment is as follows: In use, the screen component 103 is first placed inside the screening box 101, causing the insert block 205 to be inserted into the fixed plate 206, which facilitates the installation of the screen component 103. Then, the limiting frame 201 is inserted into the mounting slot, which helps to limit the screen component 103. Finally, the moving limiting plate 204 moves within the fixed frame 203, causing the limiting plate 204 to apply pressure to the limiting frame 201, thereby limiting the position of the limiting frame 201. The size of the filter mesh holes on each layer of the screen component 103... Different diameters facilitate the screening of polyoxymethylene granules. The operation of the vibration motor 102 facilitates vibration screening. The movable chute 105 moves inside the sealing baffle 104, which helps to discharge the screened polyoxymethylene granules. When vibration screening is performed, the suction fan 305 works to generate suction, which causes the adsorption hood 301 to adsorb the dust generated by vibration screening, reducing the dust in the air and thus reducing the dust concentration. Finally, the movable sealing box door 308 moves inside the slide rail 307, which helps to clean up the dust that has been sucked up.
[0026] The vibration motor 102 and the suction fan 305 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the vibration motor 102 and the suction fan 305 will not be explained in detail.
