[0002] Chemical engineering is a branch of engineering that focuses on the design, development, operation, and optimization of chemical processes to produce useful chemicals or chemically transformed products. The raw materials for chemical production cover a wide range of natural resources and chemicals, and the choice of each raw material affects the quality, cost, and sustainability of the final product.
[0003] Before being put into use, chemical raw materials need to be screened to obtain the appropriate size for processing. Since solid chemical raw materials include crystals, crystalline substances, and lumpy materials, during screening, the raw materials rub against each other, which can easily generate raw material debris. Small and light powdery debris can easily disperse in the air, which can not only pollute the environment but also pose a risk of being inhaled by workers.

[0021] Example 1
[0022] like Figure 1-4 The image shows the first embodiment of this utility model, which provides a raw material screening device for chemical production. It includes a support frame 1, a screening box 2 housed within the inner cavity of the support frame 1, a movable cover 3 hinged to the top of the screening box 2, a screen 4 fixedly connected to the bottom of the inner cavity of the screening box 2, a discharge hopper 5 fixedly connected to the bottom of the support frame 1, a fixed box 6 fixedly connected to the left side of the support frame 1, and a reciprocating moving mechanism 7 housed within the inner cavity of the fixed box 6. The reciprocating moving mechanism 7 includes a rotating disk 701. The rotating disk 701 is located at the front end of the bottom of the discharge hopper 5. The center of the bottom of the fixed box 6 is movably connected to the movable tooth frame 702 by a movable pin. The rear end of the bottom of the fixed box 6 is provided with a movable column 703. The front of the movable column 703 is fixedly connected to the tooth block 704. The movable tooth frame 702 and the tooth block 704 mesh. The left end of the movable column 703 extends to the left side of the fixed box 6, and the right end of the movable column 703 extends to the inner cavity of the support frame 1 and is fixedly connected to the left side of the screening box 2.
[0023] like Figure 1-4As shown, the support frame 1 is used to support and fix the top components. During the movement of the screening box 2, it can cooperate with the screen 4 to screen the raw materials, thereby screening out the raw materials of the required size for use in chemical production. The screening box 2 and the movable cover 3 work together to provide a sealed screening environment for the raw materials, thereby preventing raw material dust from drifting into the air and preventing dust from polluting the environment. At the same time, it prevents workers from inhaling dust and affecting their health. The discharge hopper 5 is used to discharge the screened raw materials for collection. The fixed box 6 is used to support and protect the reciprocating moving mechanism 7. The reciprocating moving mechanism 7 is used to drive the screening box 2 to move back and forth in the inner cavity of the support frame 1, so that the raw materials can tumble under the influence of inertia for screening.
[0024] Example 2
[0025] Reference Figure 3 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0026] In this embodiment, a push block 705 is fixedly connected to the front of the rotating disk 701. The front end of the push block 705 extends into the inner cavity of the movable gear frame 702 and is slidably connected to the inner cavity of the movable gear frame 702. Support rings 706 are sleeved on both sides of the surface of the movable column 703. The bottom of the support ring 706 is fixedly connected to the inner wall of the fixed box 6.
[0027] A motor 707 is fixedly connected to the bottom of the fixed box 6. The output shaft of the motor 707 passes through the inner cavity of the fixed box 6 and is connected to the bottom of the rotating disk 701. The output shaft of the motor 707 is movably connected to the inner wall of the fixed box 6 through a bearing.
[0028] like Figure 3 As shown, when the motor 707 is running, it can drive the rotating disk 701 to rotate, and the rotating disk 701 drives the push block 705 to rotate. Since the push block 705 is slidably connected to the inner cavity of the movable gear frame 702, during the rotation of the push block 705, it can cooperate with the movable pin to drive the movable gear frame 702 to reciprocate in a semi-circular motion around the movable pin. Since the movable gear frame 702 is engaged with the tooth block 704, during the rotation of the movable gear frame 702, it can cooperate with the tooth block 704 to drive the movable column 703 to reciprocate in the left and right directions. The movable column 703 then drives the screening box 2 to reciprocate in the inner cavity of the support frame 1 in order to screen the raw materials.
[0029] Example 3
[0030] Reference Figure 1 and 4 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0031] In this embodiment, through grooves 8 are provided on both sides of the support frame 1, and baffles 9 are fixedly connected to both sides of the screening box 2. One side of the baffle 9 extends into the inner cavity of the through groove 8 and is slidably connected to the inner cavity of the through groove 8.
[0032] The front and rear ends of the bottom of the through groove 8 are provided with pulleys 10, and the front and rear ends of the bottom of the baffle 9 are provided with sliding grooves 11. The top of the pulley 10 extends into the inner cavity of the sliding groove 11 and is slidably connected with the inner cavity of the sliding groove 11.
[0033] The top of the movable cover 3 is fixedly connected to the feeding pipe 12, and the top of the feeding pipe 12 is detachably connected to the sealing cover.
[0034] like Figure 1 and 4 As shown, the through groove 8 provides space for the baffle 9 to move. The baffle 9 can support the screening box 2 and also shield the upper part of the inner cavity of the support frame 1 to prevent dust from overflowing. The pulley 10 and the slide 11 work together to reduce the friction force on the baffle 9 during movement. The feeding pipe 12 facilitates the addition of raw materials into the screening box 2.
[0035] In use, first place the container for holding the raw materials at the bottom of the discharge hopper 5, and add the raw materials into the screening box 2 through the feeding pipe 12. After adding, seal the feeding pipe 12 with the sealing cap. Then start the motor 707. When the motor 707 is running, it can drive the rotating disk 701 to rotate. The rotating disk 701 drives the push block 705 to rotate. Since the push block 705 is slidably connected to the inner cavity of the movable gear frame 702, during the rotation of the push block 705, it can cooperate with the movable pin to drive the movable gear frame 702. The toothed frame 702 reciprocates in a semi-circular motion around the movable pin. Since the movable toothed frame 702 meshes with the toothed block 704, during the rotation of the movable toothed frame 702, it can work with the toothed block 704 to drive the movable column 703 to reciprocate in the left and right directions. The movable column 703 then drives the screening box 2 to reciprocate in the inner cavity of the support frame 1. Under the action of inertia, the screen 4 can screen the raw materials. The screened raw materials fall into the interior of the container through the discharge hopper 5, thereby completing the screening operation of the raw materials.
