Description

Technical Field

[0001] This utility model relates to the field of chemical raw material screening technology, specifically a chemical raw material sieve. Background Technology

[0002] Chemical raw material screening is a crucial step in chemical production. By removing impurities, the purity of chemical raw materials is improved, ensuring the accuracy of subsequent chemical reactions and the stability of product quality. Raw materials can be classified according to physical properties such as particle size and density to meet the specific particle size requirements of different chemical processes.

[0003] In the screening of chemical raw materials, vibration is usually generated by a vibrator mechanism, which makes the material on the screen surface jump and roll continuously, accelerating the screening process and improving screening efficiency. It is widely used in the screening of raw materials in chemical, food and pharmaceutical industries. However, existing screening devices usually use a single-layer screen mesh mechanism, which can only screen two kinds of chemical raw materials with different particle sizes. The range of particle sizes screened is limited, which is difficult to meet the specific requirements of chemical processes for raw material particle size. In addition, the screen mesh mechanism needs to be disassembled and cleaned after a period of use. However, the existing screen mesh mechanism is installed inside the screening device, which is relatively troublesome to disassemble and install. Therefore, a chemical raw material screen is proposed. Utility Model Content

[0005] To achieve the above objectives, a chemical raw material sieve is provided, comprising a device housing, wherein three detachable screening mechanisms are installed inside the front of the device housing, and each detachable screening mechanism includes a frame, a handle, and a screen.

[0006] The frame has mounting slots on both sides. Three first fixing blocks are fixedly connected to the left side of the device housing. A first elastic plate is fixedly connected to the other end of the first fixing block. A first mounting bracket is fixedly connected to the other end of the first elastic plate. Three second fixing blocks are fixedly connected to the right side of the device housing. A second elastic plate is fixedly connected to the other end of the second fixing block.

[0007] According to the aforementioned chemical raw material sieve, the handle is fixedly connected to the center of the front of the frame, and the screen mesh is fixedly connected to the center of the frame. The mesh size of the three screen meshes gradually decreases from top to bottom.

[0009] According to the aforementioned chemical raw material sieve, the plates corresponding to the first mounting bracket and the second mounting bracket are slidably connected to the inside of the left and right mounting slots of the detachable screening mechanism, respectively.

[0010] According to the aforementioned chemical raw material sieve, three vibrators are installed on the left side inside the outer casing of the device. Vibrating rods are installed at the output ends of the vibrators, and the upper surface of the vibrating rods is attached to the lower surface of the first mounting bracket.

The lower surface height of the discharge port is the same as the height of the connection point of the second elastic plate, and the lower surface height of the discharge port is the same as the height of the connection point of the guide plate.

[0012] According to the aforementioned chemical raw material sieve, a guide funnel is installed inside the outer casing of the device, and a collection box is slidably connected to the inside of the right side of the outer casing. The height of the detachable screening mechanism below is higher than the height of the guide funnel, the height of the guide funnel is higher than the height of the collection box, the size of the sieve is smaller than the opening size of the guide funnel, and the opening size of the guide funnel is smaller than the opening size of the collection box.

[0013] According to the aforementioned chemical raw material sieve, an inlet is provided inside the upper end of the device shell, and a feed funnel is installed at the upper end of the device shell. The inlet of the inlet and the outlet of the feed funnel are interconnected, and the outlet of the inlet is located above the upper screen.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This chemical raw material sieve, by setting up three sieves from top to bottom, can screen chemical raw materials to obtain four types of chemical raw materials with different particle sizes. Compared with a single-layer sieve mechanism, it improves the screening device's ability to screen chemical raw material particle sizes and can meet the specific requirements of chemical processes for raw material particle size.

[0016] This chemical raw material screen, by setting a first mounting bracket, a second mounting bracket, and mounting grooves, and by setting the brackets of the first mounting bracket and the second mounting bracket to slide and connect with the inside of the left and right mounting grooves respectively, realizes the rapid disassembly and installation of the detachable screening mechanism, and improves the efficiency of replacing the screening screen mechanism.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a chemical raw material sieve, including a device housing 1. Three detachable screening mechanisms 2 are installed inside the front of the device housing 1. Each detachable screening mechanism 2 includes a frame 201, a handle 202, and a screen 203. By setting the screen 203, the chemical raw materials are screened separately by setting the three screens 203 from top to bottom, resulting in four types of chemical raw materials with different particle sizes. Compared with a single-layer screen mechanism, this improves the screening of chemical raw material particle size types and can meet the specific requirements of chemical processes for raw material particle size.

[0026] The frame 201 has mounting slots 4 on both sides. Three first fixing blocks 5 are fixedly connected to the left side of the device housing 1. A first elastic plate 6 is fixedly connected to the other end of the first fixing block 5. A first mounting bracket 7 is fixedly connected to the other end of the first elastic plate 6. Three second fixing blocks 8 are fixedly connected to the right side of the device housing 1. A second elastic plate 9 is fixedly connected to the other end of the second fixing block 8. A second mounting bracket 10 is fixedly connected to the other end of the second elastic plate 9. By setting the first mounting bracket 7, the second mounting bracket 10, and the mounting slots 4, and by setting the brackets of the first mounting bracket 7 and the second mounting bracket 10 to slide and connect with the left and right mounting slots 4 respectively, the disassembly and installation of the detachable screening mechanism 2 can be quickly achieved, improving the efficiency of replacing the screening screen mechanism.

[0027] The handle 202 is fixedly connected to the center of the front of the frame 201. The screen 203 is fixedly connected to the center of the frame 201. The mesh size of the three screens 203 gradually decreases from top to bottom. The lower surface height of the first elastic plate 6 is the same as the lower surface height of the first fixed block 5. The upper surface height of the second elastic plate 9 is the same as the upper surface height of the frame 201. The height of the first mounting bracket 7 is slightly higher than the height of the corresponding second mounting bracket 10. The brackets of the first mounting bracket 7 and the second mounting bracket 10 are slidably connected to the left and right mounting slots 4 of the detachable screening mechanism 2.

[0028] Three vibrators 11 are installed on the left side inside the outer casing 1 of the device. Vibration rods 1101 are installed at the output end of the vibrators 11. The upper surface of the vibration rods 1101 is attached to the lower surface of the first mounting bracket 7. By setting the vibrators 11 to generate vibration, the chemical raw materials on the screen 203 are constantly jumping and rolling, which accelerates the screening process of the chemical raw materials and improves the screening efficiency of the screening device.

[0029] The device housing 1 has three discharge ports 12 on the right side inside. Three guide plates 13 are installed on the right side of the device housing 1. The lower surface of the corresponding discharge port 12 is at the same height as the connection point of the second elastic plate 9, and the lower surface of the corresponding discharge port 12 is at the same height as the connection point of the guide plate 13. By setting the guide plates 13, the chemical raw materials are guided so that they can fall accurately into the corresponding collection tank.

[0030] Inside the outer casing 1 of the device, a guide funnel 14 is installed. Inside the right side of the outer casing 1, a collection box 15 is slidably connected. The height of the detachable screening mechanism 2 below is higher than the height of the guide funnel 14, and the height of the guide funnel 14 is higher than the height of the collection box 15. The size of the screen 203 is smaller than the opening size of the guide funnel 14, and the opening size of the guide funnel 14 is smaller than the opening size of the collection box 15. By setting the guide funnel 14, it is convenient to concentrate the chemical raw materials, prevent the chemical raw materials from deviating during the falling process, and improve the stability of the collection box 15 in collecting chemical raw materials.

[0031] The upper end of the device housing 1 is provided with a feed inlet 16 and a feed funnel 17 is installed at the upper end of the device housing 1. The inlet of the feed inlet 16 and the outlet of the feed funnel 17 are connected to each other. The outlet of the feed inlet 16 is located above the upper screen 203. By setting the feed funnel 17, it is convenient to add chemical raw materials into the interior of the screening device.

[0032] Working principle: When in use, connect the power supply. When replacing the screening mesh mechanism, first pull the handle 202 so that the plates of the first mounting bracket 7 and the second mounting bracket 10 slide into the left and right mounting slots 4 respectively, so that the detachable screening mechanism 2 can be taken out from the inside of the screening device, thus completing the disassembly of the screening mesh mechanism. Then, align the slots of the left and right mounting slots 4 of the new detachable screening mechanism 2 with the plates of the first mounting bracket 7 and the second mounting bracket 10. Then push the detachable screening mechanism 2 so that the plates of the first mounting bracket 7 and the second mounting bracket 10 slide into the left and right mounting slots 4 respectively, until the detachable screening mechanism 2 is completely inserted into the inside of the screening device. At this time, the installation of the screening mesh mechanism is completed. Through the above process, the replacement of the screening mesh mechanism of the screening device is realized.

[0033] When performing multi-layer screening of chemical raw materials, the chemical raw materials are first added to the screening device through the feed funnel 17. Under the combined action of the upper screen 203 and the vibrator 11, the chemical raw materials vibrate and separate. The larger chemical raw materials are discharged through the upper outlet 12, while the remaining chemical raw materials pass through the mesh of the upper screen 203 and fall into the middle screen 203. Under the combined action of the middle screen 203 and the vibrator 11, the chemical raw materials are vibrated and separated. The medium-sized chemical raw materials are discharged through the middle outlet 12, while the remaining chemical raw materials pass through the mesh of the middle screen 203 and fall into the lower screen 203. Under the combined action of the lower screen 203 and the vibrator 11, the chemical raw materials are vibrated and separated. The smaller chemical raw materials are discharged through the lower outlet 12, while the remaining chemical raw materials pass through the mesh of the lower screen 203 and fall into the guide funnel 14. After being concentrated by the guide funnel 14, they fall into the collection box 15, realizing the collection of the smallest particle size chemical raw materials. Through the above process, the screening device performs multi-layer screening of chemical raw materials.

[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
