DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The present application will be further described in detail below with reference to the drawings and embodiments.

[0031] Referring to Figures 1 to 3 , an embodiment of the present application provides a material screening device for chemical production, including a base 1 and a screening box 2. The screening box 2 is arranged above the base 1. A screen 3 is slidably connected inside the screening box 2. Disassembly and assembly components 4 for quickly disassembling and assembling the screen 3 are fixedly installed on both sides of the screening box 2. The disassembly and assembly components 4 include installation frames 401 fixedly installed on both sides of the screening box 2. A screening component 5 for improving the screening efficiency is fixedly installed on one side of the base 1.

[0032] A clamping rod 402 is slidably connected inside the mounting frame 401. The clamping rod 402 penetrates through one side of the mounting frame 401. A sliding plate 403 is fixedly installed on one side of the clamping rod 402. A first spring 404 is fixedly installed on one side of the sliding plate 403. Mounting rods 405 are fixedly installed on both sides above the screen 3. The two mounting rods 405 respectively penetrate through the upper surfaces of the two mounting frames 401 and are slidably connected with the mounting frames 401. A clamping groove 406 that fits the clamping rod 402 is formed on one side of each of the two mounting rods 405.

[0033] A second spring 407 is fixedly installed inside the mounting frame 401. A limiting plate 408 is fixedly installed at the top of the second spring 407. The limiting plate 408 is arranged directly below the mounting rod 405.

[0034] By pulling the two clamping rods 402 outwards, when the clamping rods 402 disengage from the clamping grooves 406, the limiting plate 408 moves upwards by the elastic force of the second spring 407, thereby driving the mounting rods 405 to move upwards, and the screen 3 can be disassembled. At the same time, the limiting plate 408 rises to the position of the clamping rod 402 to limit the clamping rod 402. When it is necessary to install or replace the screen 3, just insert the mounting rods 405 on both sides of the screen 3 into the two mounting frames 401. The mounting rods 405 move downwards, driving the limiting plate 408 to move downwards. When the clamping groove 406 moves to the position of the clamping rod 402, the clamping rod 402 moves towards the clamping groove 406 by the elastic force of the first spring 404, and the mounting rod 405 can be clamped, completing the installation or replacement of the screen 3, solving the problems that the existing screen 3 is generally fixedly installed inside the screening device or installed by bolts. The fixedly installed screen 3 is not convenient to clean, and it is not convenient to screen materials of different sizes. The installation and disassembly of the bolt installation method are relatively cumbersome, and the work efficiency is low.

[0035] Refer to Figure 1 and Figure 4 In one aspect of this embodiment, the screening assembly 5 includes a mounting plate 501 fixedly installed on one side of the base 1. A motor 502 is fixedly installed below the mounting plate 501. An output end of the motor 502 is fixedly installed with a turntable 503. A connecting rod 504 is fixedly installed above the turntable 503. An articulated rod 505 is rotatably connected above the connecting rod 504. The other end of the articulated rod 505 is articulated with one side of the screening box 2.

[0036] Sliding rails 506 are fixedly installed on both sides of the screening box 2. Support plates 507 are fixedly installed on both sides of the base 1. Fixed frames 508 are fixedly installed on one side of each of the two support plates 507. The two fixed frames 508 are respectively slidably connected with the two sliding rails 506.

[0037] The turntable 503 is driven to rotate by the motor 502. The turntable 503 drives the connecting rod 504 fixedly installed above to rotate. The connecting rod 504 drives the articulated rod 505 rotatably connected above to perform a circular motion. Since one side of the screening box 2 is articulated with the articulated rod 505, and at the same time, the screening box 2 is limited by the settings of the slide rail 506, the support plate 507 and the fixed frame 508, the articulated rod 505 drives the screening box 2 to reciprocate left and right, so that the material can be fully screened, solving the problems that the existing screening device has low screening efficiency and is difficult to fully screen the material.

[0038] Referring to Figure 1 and Figure 4 In one aspect of this embodiment, an inclined plate 6 is fixedly installed at the bottom of the screening box 2. An outlet 7 is opened on one side of the screening box 2. A baffle 8 is slidably connected inside the outlet 7.

[0039] A collection box 9 is placed above the base 1. The collection box 9 is placed on one side of the outlet 7.

[0040] After the screening is completed, the baffle 8 is pulled out to expose the outlet 7. The material is moved towards the outlet 7 through the inclined plate 6, and the material is discharged through the outlet 7. The collection box 9 placed on the base 1 facilitates the collection of the material. After the collection is completed, the baffle 8 can be inserted.

[0041] All the electrical equipment in this solution is powered by an external power supply.

[0042] Working principle: When the material screening device for chemical production is in use, the screen 3 should be installed inside the screening box 2 first, and then the material to be screened is poured into the screening box 2. Then the motor 502 is started. The motor 502 drives the turntable 503 to rotate. The turntable 503 drives the connecting rod 504 fixedly installed above to rotate. The connecting rod 504 drives the articulated rod 505 rotatably connected above to perform a circular motion. The articulated rod 505 drives the screening box 2 to reciprocate left and right, so that the material can be fully screened. After the screening is completed, the baffle 8 is pulled out to expose the outlet 7. The material is moved towards the outlet 7 through the inclined plate 6, and the material is discharged through the outlet 7. The collection box 9 placed on the base 1 facilitates the collection of the material. After the collection is completed, the baffle 8 can be inserted. When it is necessary to clean or replace the screen 3, only need to pull the two clamping rods 402 outwards. When the clamping rods 402 disengage from the clamping grooves 406, the limiting plate 408 moves upwards under the elastic force of the second spring 407, and then drives the mounting rod 405 to move upwards, so that the screen 3 can be disassembled.
