Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, and more specifically, to a grinding device for chemical production. Background Technology

[0002] Chemical industry is an abbreviation for chemical processes, chemical industry, and chemical engineering. It encompasses all technologies that use chemical methods to alter the composition and structure of substances or synthesize new substances. The resulting products are called chemicals or chemical products. Initially, these products were produced in small workshops, later evolving into factories and gradually forming a specific production industry: the chemical industry. In chemical production, limestone is ground into powder using grinding equipment to be used as a raw material for producing calcium carbonate, which is then used as a filler in industries such as papermaking and plastics.

[0003] Existing grinding mills in chemical production typically pre-crush limestone using a crushing mechanism at the top. However, during crushing, limestone fragments are easily scattered due to the impact between the crushing wheel and the limestone. Existing grinding mills in chemical production cannot effectively shield these scattered limestone fragments, which can easily lead to workers being injured by them. Therefore, we propose a grinding mill for chemical production. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a grinding device for chemical production, so as to solve the technical problem that limestone fragments are easily splashed when the existing grinding devices for chemical production pre-crush limestone.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a grinding device for chemical production, including a grinding mill body, the grinding mill body including a base frame, a grinding mechanism provided on the base frame, a crushing mechanism provided at the feed end of the grinding mechanism, and a protective mechanism, the protective mechanism being located on top of the crushing mechanism;

[0006] The protective mechanism includes two feed bins that are vertically connected to each other. The bottom of the feed bin located at the bottom covers the feed end of the crushing mechanism. Two baffles are symmetrically arranged in the middle of the two feed bins. Short shafts are fixedly connected to both ends of opposite sides of the two baffles. The short shafts pass through the walls of the feed bins. Slider blocks are provided on both sides of the middle of the baffles. An arc-shaped through groove with the short shaft as the axis is opened in the feed bin relative to the position of the slider. One end of the slider passes through the arc-shaped through groove and extends to the outside. A hook spring is rotatably connected to the top of the feed bin relative to the arc-shaped through groove. One end of the hook spring is rotatably connected to one end of the slider.

[0007] Preferably, the feed hopper has an installation cavity located relative to the short axis, one side of the installation cavity is connected to the outside of the feed hopper, and the other side of the installation cavity is connected to the arc-shaped through groove.

[0008] Preferably, the mounting cavity and the arc-shaped through groove are located at the same axis, and the radius of the mounting cavity is the same as the radius of the arc-shaped through groove.

[0009] Preferably, the mounting cavity is provided with a baffle plate, one side of which extends to the outside of the feed hopper, and the other side of which extends to the inner wall of the arc-shaped through groove and is fixedly sleeved on the middle of the slider.

[0010] Preferably, the baffle is disc-shaped, the radius of the baffle is the same as the radius of the mounting cavity, and the middle part of the baffle is fixedly sleeved on the middle surface of the short shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model features a protective mechanism at the top of the crushing mechanism. The accumulation of limestone blocks presses down on the two top baffles and the short shaft, causing the slider to slide down along the arc-shaped groove and stretch the hook spring. This causes the limestone blocks to slide onto the two baffles in the bottom feed hopper. The top two baffles, due to the reset of the hook spring, flip upward to close the top feed hopper. As the limestone blocks on the bottom two baffles accumulate, they flip downward, allowing the limestone blocks to fall into the crushing mechanism for crushing. The hook spring also closes the bottom feed hopper due to its elasticity. The design of two layers of feed hoppers and baffles forms an intermediate storage hopper. During continuous feeding, one set of the top or bottom baffles is always in a closed state, thus preventing limestone fragments from splashing when the crushing mechanism is crushing the limestone blocks.

[0013] 2. When the short shaft of this utility model rotates, it drives the disc-shaped baffle to rotate around the short shaft as the axis, so that the baffle always closes the arc-shaped through groove, which can effectively prevent the dust generated by the crushing mechanism from crushing limestone blocks from overflowing from the arc-shaped through groove and polluting the working environment.

[0019] like Figures 1 to 3 As shown, this utility model relates to a grinding device for chemical production, which includes a grinding mill body 1 and a protective mechanism 2.

[0020] like Figure 1 As shown, the grinding mill body 1 includes a base frame 101, and a grinding mechanism 102 is provided on the base frame 101. The feeding end of the grinding mechanism 102 is provided with a crushing mechanism 103. In this embodiment, the grinding mill body 1 is a grinding device that is currently available on the market for the production of limestone in the chemical industry. The crushing mechanism 103 is used to pre-crush the limestone, and the grinding mechanism 102 is used to grind the crushed limestone into powder.

[0021] like Figures 1 to 3 As shown, the protective mechanism 2 is located on top of the crushing mechanism 103.

[0022] Specifically, such as Figures 1 to 3As shown, the protective mechanism 2 includes two feed bins 201 that are vertically connected to each other. The bottom feed bin 201 is covered by the feed end of the crushing mechanism 103. Two baffles 202 are symmetrically arranged in the middle of the two feed bins 201. Short shafts 203 are fixedly connected to both ends of opposite sides of the two baffles 202. The short shafts 203 pass through the bin wall of the feed bin 201. Sliding blocks 2021 are provided on both sides of the middle of the baffles 202. The feed bin 201 has an opening relative to the sliding blocks 2021 with the short shafts 203 as the axis. The curved through-slot 2011 has a slider 2021 with one end passing through it and extending to the outside. A hook spring 204 is rotatably connected to the top mounting shaft of the feed bin 201 relative to the curved through-slot 2011. One end of the hook spring 204 is rotatably connected to one end of the slider 2021. When limestone blocks are placed on the two baffles 202 inside the top feed bin 201, the accumulation of limestone blocks will press down on the two baffles 202 and the short shaft 203, causing them to rotate downwards. Simultaneously, this will cause the slider 2021 to rotate around the short shaft 2021. 3. The axis slides downward along the arc-shaped through groove 2011 and stretches the hook spring 204, causing the limestone blocks to slide down the trough formed by the opposite sides of the two baffles 202 onto the two baffles 202 inside the bottom feed hopper 201. At this time, the two baffles 202 in the top feed hopper 201 are rotated upward and closed by the reset of the hook spring 204. As the limestone blocks accumulate on the two baffles 202 in the bottom feed hopper 201, the two baffles 202 will rotate downward. The rotation causes the limestone blocks to fall into the crushing mechanism 103 for crushing. After the limestone has completely fallen into the crushing mechanism 103, the two bottom baffles 202 will also close the bottom feed hopper 201 due to the elasticity of the hook spring 204. The design of the upper and lower two-layer feed hoppers 201 and baffles 202 forms an intermediate storage hopper. During the continuous feeding process, one set of the two baffles 202 at the top or bottom is always in a closed state, thereby preventing limestone fragments from splashing when the crushing mechanism 103 crushes the limestone blocks.

[0023] Furthermore, such as Figure 2 , Figure 3As shown, a mounting cavity 2012 is formed in the feed hopper 201 relative to the short shaft 203. One side of the mounting cavity 2012 communicates with the outside of the feed hopper 201, and the other side of the mounting cavity 2012 communicates with the arc-shaped through groove 2011. The mounting cavity 2012 and the arc-shaped through groove 2011 are located at the same axis, and the radius of the mounting cavity 2012 is the same as the radius of the arc-shaped through groove 2011. A baffle 205 is provided inside the mounting cavity 2012. One side of the baffle 205 extends to the outside of the feed hopper 201, and the other side of the baffle 205 extends to the arc-shaped through groove 2011. The inner wall of the through groove 2011 is fixedly sleeved in the middle of the slider 2021. The baffle 205 is disc-shaped, and the radius of the baffle 205 is the same as the radius of the mounting cavity 2012. The middle part of the baffle 205 is fixedly sleeved on the middle surface of the short shaft 203. When the short shaft 203 rotates, it drives the disc-shaped baffle 205 to rotate around the short shaft 203 as the axis, so that the baffle 205 always closes the arc-shaped through groove 2011, which can effectively prevent the dust generated by the crushing mechanism 103 from crushing limestone blocks from overflowing from the arc-shaped through groove 2011 and polluting the working environment.

[0024] Working Principle: This embodiment provides a grinding device for chemical production. In use, limestone blocks are placed on the two baffles 202 inside the top feed hopper 201. Due to the accumulation of limestone blocks, the two baffles 202 and the short shaft 203 are pressed downwards, simultaneously causing the slider 2021 to slide downwards along the arc-shaped groove 2011 with the short shaft 203 as its axis, stretching the hook spring 204. This causes the limestone blocks to slide down the trough formed by the opposing sides of the two baffles 202 onto the two baffles 202 inside the bottom feed hopper 201. At this time, the two baffles 202 in the top feed hopper 201 are rotated upwards and closed by the reset of the hook spring 204. As limestone blocks accumulate on the two baffles 202 inside the top feed hopper 201 and the bottom feed hopper 201, the two baffles 202 will flip downwards, causing the limestone blocks to fall into the crushing mechanism 103 for crushing. After the limestone blocks have completely fallen into the crushing mechanism 103, the bottom baffles 202 will also close the bottom feed hopper 201 due to the elasticity of the hook spring 204. At the same time, when the short shaft 203 rotates, it drives the disc-shaped baffle 205 to rotate around the short shaft 203 as the axis, so that the baffle 205 always closes the arc-shaped through groove 2011, which can effectively prevent the dust generated by the crushing mechanism 103 from crushing limestone blocks from overflowing from the arc-shaped through groove 2011.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations.
