Description

Technical Field

[0001] This invention belongs to the field of grinding equipment technology, specifically relating to a raw material crushing and grinding device for chemical product production. Background Technology

[0002] The crushing of chemical raw materials is an important step in chemical production. Its purpose is to crush solid chemical raw materials into smaller particles to improve the mixing uniformity, reaction efficiency and product quality in subsequent processes. Depending on the crushing equipment and process, crushing effects of different particle sizes and morphologies can be achieved.

[0003] Existing crushing machines typically include mechanical crushers, air jet mills, and grinders. When using a grinder to crush materials, the grinding precision of the grinder is usually not adjustable. Therefore, when inputting raw materials of different particle sizes, the processing effect is not ideal for materials that are too fine or too coarse. Materials that are too coarse can easily cause the grinder to clog, while materials that are too fine can easily pass through the grinding wall, resulting in ineffective mechanical work.

Detailed Implementation

[0023] To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Please see Figures 1-5According to one embodiment of the present invention, a raw material crushing and grinding device for chemical product production has a relative first direction x. The raw material crushing and grinding device for chemical product production includes a base component 1, which includes a base plate 101, limiting rods 102, elastic elements 103, and guide rods 104. A plurality of limiting rods 102 are fixedly disposed on the base plate 101, and elastic elements 103 are movably sleeved on the limiting rods 102. A guide rod 104 is also rotatably assembled on the base plate 101. The guide rod 104 moves along the first direction x. A grinding chamber assembly 2 is provided, comprising a grinding cylinder 201, a grinding wall 202, a discharge pipe 203, an outer annular groove 204, and a feed hopper 205. The grinding cylinder 201 is coaxially arranged with the guide rod 104 and rotatably mounted on the base plate 101. The grinding wall 202 is fixedly mounted on the inner wall of the grinding cylinder 201. A discharge pipe 203 is also provided at the bottom of the grinding cylinder 201. One end of the discharge pipe 203 is connected to the grinding cylinder 201, and the outer wall of the other end of the discharge pipe 203 is fixedly provided with an outer annular groove 204. A feed hopper 205 is also provided at the top of the grinding cylinder 201. A feeding hopper 205 is used to output raw materials to be crushed into a grinding cylinder 201. A grinding assembly 3 includes a lifting plate 301, a first drive shaft 302, a second drive shaft 303, a shelf 304, a grinding shaft body 305, and a grinder 306. One end of the lifting plate 301 is slidably sleeved on a limiting rod 102 and movably abuts against the elastic element 103. The other end of the lifting plate 301 is rotatably equipped with the first drive shaft 302, which is limited and mounted on the lifting plate 301. The first drive shaft 302 is positioned along the first... With the direction x set, one end of the second drive shaft 303 is slidably mounted on the first drive shaft 302, and the other end of the second drive shaft 303 is rotatably connected to a shelf 304. The shelf 304 is slidably mounted on the base plate 101 along the first direction x. One end of the grinding shaft 305 is rotatably mounted on the shelf 304, and the other end of the grinding shaft 305 is connected to the second drive shaft 303. A grinder 306 is fixedly connected to the bottom of the grinding shaft 305. The grinder 306 is disposed in the inner cavity of the grinding cylinder 201 and is coaxially arranged with the guide rod 104.

[0025] In practical application, when using this device to crush and grind chemical raw materials, the feed hopper 205 at one end of the grinding cylinder 201 is used to input the chemical raw materials to be processed. Since the bottom of the grinding cylinder 201 is provided with a discharge pipe 203, and the outer wall of the discharge pipe 203 is provided with an outer annular groove 204, the lifting plate 301 is fixedly sleeved and assembled on the outer annular groove 204. Furthermore, the lifting plate 301 is elastically slidably assembled on several limiting rods 102. Therefore, when the device is in crushing and grinding operation, the greater the mass of the raw material in the grinding cylinder 201, the greater the displacement of the lifting plate 301 in the first direction x. That is, the lifting plate 301 and the bottom plate 101... The closer the distance between them, and during the grinding process, the more the first drive shaft 302 rotates under the action of the drive source. Since the second drive shaft 303 is slidably inserted on the first drive shaft 302, the second drive shaft 303 can transmit power to one side of the grinding shaft body 305 while rotating with the first drive shaft 302, so that the grinding shaft body 305 rotates with the second drive shaft 303. The bottom of the grinding shaft body 305 is fixedly provided with a grinder 306, and the grinder 306 is rotatably sleeved on the guide rod 104. Therefore, during the rotation of the grinder 306, the grinder 306 and the grinding wall 202 form a relative rotation and enter the grinding cylinder. Under the influence of gravity, the material in the inner cavity of grinding cylinder 201 continuously flows into the gap between the grinding wall 202 and the grinder 306. Through the continuous friction between the grinding wall 202 and the grinder 306, the raw material is continuously ground in the gap, allowing the ground small-diameter material to pass through the gap and fall into the discharge pipe 203, and be discharged outward along the discharge pipe 203. In the actual grinding process, when the raw material particle size input from the side of the feed hopper 205 is large, due to the large gap between the materials, more air is filled between the materials. Since the volume of the storage space of the grinding cylinder 201 is fixed, the actual mass of the large-diameter material is relatively light. Therefore, the mass can be reduced by adjusting the first drive shaft 302 and the second drive shaft. The relative sliding distance between the grinding wall 202 and the grinder 306 is adjusted to regulate the distance between them. When grinding large-diameter materials, the gap between the grinding wall 202 and the grinder 306 can be increased to avoid low grinding efficiency or even material jamming caused by a small gap. When grinding small-diameter materials, since the gap between small-diameter materials is small, the mass is large for the same volume. The gap between the grinding wall 202 and the grinder 306 can be reduced to achieve finer grinding and prevent small-diameter materials from passing directly through the gap and generating useless work. This allows the device to automatically adjust the grinding precision by inputting the particle size of the raw material, thereby improving grinding efficiency and effect.

[0026] In one embodiment, the device is limited to grinding raw materials of the same type, and the grinding body is mostly powder, which is not suitable for crushing block materials or fluid materials. This will not be described in detail here.

[0027] Please see Figure 4 In a preferred embodiment of the present invention, the base component 1 further includes a guide plate 105, which is fixedly disposed on the base plate 101 and disposed near the discharge pipe 203, for discharging the ground raw material in the grinding cylinder 201.

[0028] In practical application, the guide plate 105 is fixedly installed on the base plate 101 and inclinedly arranged through the guide rod 104, so that the grinding material falling into the discharge pipe 203 can be discharged through the guide plate 105.

[0029] Please see Figure 2 In a preferred embodiment of the present invention, the grinding chamber assembly 2 further includes a discharge hopper 206, which is fixedly disposed on one side of the wall of the grinding cylinder 201 and disposed near the end of the feed hopper 205, for discharging excess raw materials from the cavity of the grinding cylinder 201.

[0030] In practical application, the discharge hopper 206 is located on one side of the feed hopper 205 so that when raw materials are continuously fed into the feed hopper 205, when the raw materials fill the inner cavity of the grinding cylinder 201, the excess raw materials can be discharged through the discharge hopper 206, so that the volume of the inner cavity of the grinding cylinder 201 is fixed, so that the mass of materials can be compared under the same volume.

[0031] Please see Figure 2 In a preferred embodiment of this invention, the grinding assembly 3 further includes a driven wheel 307, a driven wall 308, and a driver 309. The driven wheel 307 is slidably disposed on the bottom of the first transmission shaft 302 and is in drive connection with the first transmission shaft 302. The driver 309 is fixedly disposed on the base plate 101. One end of the driven wall 308 is rotatably sleeved on the first transmission shaft 302, and the other end of the driven wall 308 is rotatably sleeved on the driver 309. The driven wheel 307 and the driver 309 are in drive connection, and the other end of the driver 309 is in drive connection with the guide rod 104.

[0032] In practical application, the driver 309 is fixedly mounted on the base plate 101, and the driven wall 308 is assembled between the first transmission shaft 302 and the driver 309. In the driving state, the driver 309 can drive the driven wheel 307 to rotate synchronously. The driven wheel 307 is slidably sleeved on the first transmission shaft 302 and is in transmission connection with the first transmission shaft 302, so it can synchronously drive the first transmission shaft 302 to rotate. The first transmission shaft 302 and the second transmission shaft 303 are slidably connected, so they can drive the synchronous rotation of the second transmission shaft 303, so that when the lifting plate 301 is raised and lowered in the first direction x, the driver 309, the first transmission shaft 302 and the second transmission shaft 303 always maintain a transmission state.

[0033] Please see Figure 3 In a preferred embodiment of the present invention, the raw material crushing and grinding device for chemical product production has a first grinding surface a1 and a second grinding surface a2. The first grinding surface a1 is disposed on the side of the grinding wall 202 facing the grinding shaft 305, and the second grinding surface a2 is disposed on the side of the grinder 306 facing the grinding wall 202. The first grinding surface a1 and the second grinding surface a2 are spaced apart.

[0034] In practical application, the grinding first surface a1 and the grinding second surface a2 are spaced apart, and the grinding first surface a1 and the grinding second surface a2 are the same curved wall. Therefore, when the grinding second surface a2 moves up and down in the first direction x, the distance between the grinding first surface a1 and the grinding second surface a2 can be adjusted synchronously, and the distance value is fixed so that the particle size of the raw material after grinding tends to a fixed particle size range.

[0035] Please see Figure 2 and Figure 5 In a preferred embodiment of the present invention, the raw material crushing and grinding device for chemical product production further includes an adjustment mechanism 4. The adjustment mechanism 4 includes a first adjustment rack 401, a first transmission gear 402, a second transmission gear 403, a second adjustment rack 404, and an adjustment arm 405. The first adjustment rack 401 is fixedly disposed at one end of the lifting plate 301. The first transmission gear 402 is fixedly disposed on the base plate 101, and one end of the first transmission gear 402 is meshed with the first adjustment rack 401. The other end of the first transmission gear 402 is coaxially fixedly connected to the second transmission gear 403. One end of the second adjustment rack 404 is meshed with the second transmission gear 403, and the other end of the second adjustment rack 404 is fixedly connected to the adjustment arm 405. The end of the adjustment arm 405 is positioned and sleeved on the second transmission shaft 303.

[0036] In practical application, when the lifting plate 301 moves up and down in the first direction x, the first adjusting rack 401 fixedly connected to one end of it can synchronously engage and drive the first transmission gear 402 to rotate. Since the first transmission gear 402 is fixedly connected to the second transmission gear 403 at one end, the second transmission gear 403 can also engage and drive the second adjusting rack 404 to slide in the first direction x during synchronous rotation. Since the end of the second adjusting rack 404 is positioned and connected to the second transmission shaft 303 through the adjusting arm 405, the second transmission shaft 303 can be pulled to move on the first transmission shaft 302 by the sliding of the second adjusting rack 404, thereby driving the grinding shaft 305 and the grinder 306 to move in the first direction x.

[0037] In one embodiment, the diameter of the first transmission gear 402 is smaller than the diameter of the second transmission gear 403. When the movement distance of the lifting plate 301 in the first direction x is m, the movement distance of the second adjusting rack 404 in the meshing process is greater than m, so that the lifting speed of the grinding shaft 305 in the first direction x is greater than the lifting speed of the grinding cylinder 201 in the first direction x.

[0038] The above embodiments of the present invention provide a raw material crushing and grinding device for chemical product production. By slidingly assembling a liftable grinding cylinder 201 on the base plate 101 and slidingly assembling a liftable grinder 306 inside the grinding cylinder 201, the grinding precision can be automatically adjusted according to the particle size of the input raw material, thereby improving the grinding efficiency and effect and avoiding ineffective work.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
