Description

Technical Field

[0001] The invention relates to the technical field of activated carbon, and in particular to a modified activated carbon dust-free crushing and grinding integrated device. Background Art

[0002] Activated carbon is amorphous carbon in the form of black powder, block, granular and honeycomb, and also regularly arranged crystalline carbon. In addition to carbon, activated carbon also contains two types of admixtures. One type is chemically combined elements, mainly oxygen and hydrogen. During the activated carbon processing, the activated carbon needs to be ground.

[0003] However, there are still the following problems in actual operation:

[0004] In the process of crushing activated carbon by the equipment, a part of the activated carbon that is crushed into powder will float in the air. The common method is to remove dust through dust removal equipment, which is easy to cause a certain loss of activated carbon raw materials and increase production costs. At the same time, in the process of crushing activated carbon, larger activated carbon particles that do not reach the appropriate powder particle size will be produced. These activated carbon particles often need to be recovered first and then crushed for the second time, which is troublesome and requires a secondary crushing process, reducing production efficiency. Summary of the invention

[0005] The object of the present invention is to provide an integrated device for dust-free crushing and grinding of modified activated carbon to solve the problems raised in the above-mentioned background technology.

In the process of crushing the activated carbon, the activated carbon enters the interior of the crushing bin through the feed inlet, and the crushing roller rotates under the drive of the first motor, and the activated carbon material is squeezed and crushed between the two crushing rollers.

[0007] Furthermore, a sieve plate is arranged below the crushing roller, and the sieve plate is arranged at an angle as a whole.

Spherical particle protrusions are arranged on the surface of the particle roller. The rotating shaft of the particle roller is connected to the first motor through a gear box. A material guide slope is arranged at the bottom of the crushing bin, and the bottom of the material guide slope is connected to the grinding bin. The crushed activated carbon is screened by the inclined sieve plate to screen out particles of suitable particle size. The particle roller is driven to rotate by the first motor, and the spherical particle protrusions on the surface of the particle roller vibrate and collide with the sieve plate, which drives the sieve plate to shake, thereby improving the screening efficiency of the sieve plate.

A collecting bin is provided below the grinding disk, and the collecting bin is detachably connected to the grinding disk through a snap. Activated carbon of suitable particle size enters the interior of the grinding disk, and the turntable drives the grinding roller for grinding.

When the fan blade rotates, the air inside the crushing bin is absorbed, and at the same time, the activated carbon powder in the air is also sucked out to prevent the activated carbon powder from spreading in the air and affecting the health of the staff and production costs.

[0011] Furthermore, an intercepting filter is provided in the middle of the dust suction duct, and the rotating shaft passes through the intercepting filter from the middle. A sweeping brush is fixedly connected to the middle of the rotating shaft, and the sweeping brush is in contact with the intercepting filter. A powder return channel is provided on the side of the dust suction duct, and the powder return channel is provided on the side of the intercepting filter. The powder return channel is connected to the top of the grinding bin away from the dust suction duct, and a connecting port is provided on the bottom side of the dust suction duct. The intercepting filter intercepts the activated carbon powder, and the sweeping brush will clean the activated carbon powder on the surface of the intercepting filter when it rotates, and the cleaned activated carbon powder will directly return to the grinding bin through the powder return channel for the grinding process.

The activated carbon particles sieved out by the sieve plate slide into the return box, and the activated carbon particles entering the return box are scooped up by the return shovel on the surface of the transmission belt and transmitted upward to the position of the delivery outlet to complete the return of the material.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The design of the crushing roller of the present invention enables the activated carbon to be quickly crushed when squeezed, thereby improving the material processing efficiency. With the help of the combination of the inclined screen plate and the particle roller, particles of suitable particle size can be effectively screened out, avoiding the waste of unqualified materials. The integrated design of crushing and grinding saves equipment space and reduces installation and maintenance costs. The design of the grinding roller and the scraper ensures that the activated carbon adhering to the inner wall of the grinding disc can be effectively scraped, thereby improving the comprehensiveness and efficiency of the grinding.

[0016] 2. In the process of crushing the activated carbon of the present invention, the fan blades absorb the air inside the crushing bin when they rotate, and at the same time, the activated carbon powder in the air is also sucked out to prevent the activated carbon powder from spreading in the air and affecting the health of the staff and the production cost. The interception filter intercepts the activated carbon powder, and the sweeping brush cleans the activated carbon powder on the surface of the interception filter when it rotates. The cleaned activated carbon powder is directly returned to the grinding bin through the powder return channel for the grinding process, which can quickly recover the activated carbon powder in the air and significantly reduce the dust content in the air. By recovering the activated carbon powder in the air, the loss of raw materials is reduced, thereby reducing the production cost. The sweeping brush design can automatically clean the interception filter, ensure the long-term stable operation of the equipment, reduce the need for manual cleaning, and at the same time, the cleaned activated carbon powder can quickly enter the subsequent production steps, thereby improving production efficiency.

[0017] 3. In the present invention, the activated carbon particles screened out by the sieve plate slide into the interior of the return box, and the fourth motor drives the second rotating shaft to rotate. At this time, the second rotating shaft will drive the transmission belt to rotate, and the activated carbon particles entering the return box will be scooped up by the return shovel on the surface of the transmission belt, and then rotated and transmitted upward until they are transmitted to the position of the delivery outlet, completing the return of materials. The activated carbon particles that do not reach the appropriate particle size can be quickly recovered, avoiding the complicated operation of secondary crushing, and improving the overall efficiency of the production line. The unqualified particles are directly sent back to the crushing bin through the return box, shortening the cycle time of material processing, and improving the continuity of production. The return of materials is realized by the return shovel driven by the motor, which reduces manual operation and improves the intelligence level of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to solve the technical problems, this utility provides the following technical solutions:

[0027] Example 1

[0028] like Figure 1-4 As shown, a modified activated carbon dust-free crushing and grinding integrated device of the present embodiment includes a crushing bin 1 and a grinding bin 2. The crushing bin 1 is arranged as a whole above the grinding bin 2. A feed port 12 is arranged on the top of the crushing bin 1. Two crushing rollers 11 are arranged inside the crushing bin 1.

The crushing roller 11 rotates under the drive of the first motor 13, and the activated carbon material is squeezed and crushed between the two crushing rollers 11.

[0029] In this embodiment, a sieve plate 15 is arranged below the crushing roller 11, and the sieve plate 15 is arranged inclined as a whole. A material guide port 18 and a return port 19 are opened on the side of the crushing bin 1 close to the return material component 4, and the return material port 19 is arranged above the crushing roller 11. The inclined bottom end of the sieve plate 15 is connected to the material guide port 18, and a particle roller 16 is arranged below the inclined top end of the sieve plate 15. The surface of the particle roller 16 is provided with spherical particle protrusions. The rotating shaft of the particle roller 16 is connected to the first motor 13 through the gear box 14. A material guide slope 17 is provided at the bottom of the crushing bin 1, and the bottom of the material guide slope 17 is connected to the grinding bin 2. The crushed activated carbon is screened through the inclined sieve plate 15 to screen out particles of suitable particle size, and the activated carbon that does not meet the requirements will be discharged through the return port 19. When screening activated carbon particles, the particle roller 16 is driven to rotate by the first motor 13, and the spherical particle protrusions on the surface of the particle roller 16 vibrate and collide with the sieve plate 15, driving the sieve plate 15 to shake, thereby improving the screening efficiency of the sieve plate 15.

[0030] Specifically, a grinding disc 21 is arranged on the top of the grinding bin 2, a sieve hole 22 is opened on the bottom surface of the grinding disc 21, a turntable 23 is arranged inside the grinding disc 21, a grinding roller 24 is rotatably connected to the side of the turntable 23, a scraper 25 is connected to the end of the grinding roller 24 away from the turntable 23, and the side of the scraper 25 is in contact with the inner wall of the grinding disc 21, a second motor 26 is arranged at the bottom of the grinding disc 21, and the output shaft of the second motor 26 is fixedly connected to the central rotating shaft of the turntable 23, and the lower part of the grinding disc 21 is connected to the rotating shaft of the turntable 23.

The turntable 23 rotates under the drive of the second motor 26. The turntable 23 drives the grinding roller 24 to grind. The scraper 25 of the grinding roller 24 fits with the inner wall of the grinding disc 21 to scrape the activated carbon adhered to the side wall of the grinding disc 21 to improve the grinding efficiency. The ground activated carbon falls into the collecting bin 27 below through the sieve hole 22.

[0031] Specifically, the design of the crushing roller 11 enables the activated carbon to be quickly crushed when squeezed, thereby improving the material processing efficiency. With the help of the combination of the inclined screen plate 15 and the particle roller 16, particles of suitable particle size can be effectively screened out to avoid the waste of unqualified materials. The integrated design of crushing and grinding saves equipment space and reduces installation and maintenance costs. The design of the grinding roller 24 and the scraper 25 ensures that the activated carbon adhering to the inner wall of the grinding disc 21 can be effectively scraped, thereby improving the comprehensiveness and efficiency of the grinding.

[0032] Example 2

[0033] In the process of equipment crushing activated carbon, part of the activated carbon that is crushed into powder will float in the air. The common method is to remove dust through dust removal equipment, which can easily cause a certain loss of activated carbon raw materials and increase production costs.

[0034] To further solve the above problems, refer to Figure 1 as well as Figure 5As shown, the present embodiment provides a dust-free component structure that can quickly recycle activated carbon powder in the air. A dust-free component 3 is arranged on one side of the crushing bin 1. The dust-free component 3 includes a dust suction pipe 31. The top of the dust suction pipe 31 is connected with the inside of the crushing bin 1 through a pipe. A rotating shaft 34 is arranged inside the dust suction pipe 31. A third motor 33 is arranged at the bottom of the dust suction pipe 31. The output shaft of the third motor 33 is fixedly connected to the rotating shaft 34. A fan blade 35 is arranged at one end of the rotating shaft 34 away from the third motor 33. In the process of crushing the activated carbon, the third motor 33 drives the rotating shaft 34 to rotate, thereby driving the fan blade 35 in the dust suction pipe 31 to rotate. When the fan blade 35 rotates, it absorbs the air inside the crushing bin 1, and at the same time, it also sucks out the activated carbon powder in the air, so as to prevent the activated carbon powder from being scattered in the air and affecting the health of the staff and the production cost.

[0035] In this embodiment, an interception filter 36 is provided in the middle of the dust suction pipe 31, and the rotating shaft 34 passes through the interception filter 36 from the middle. A sweeping brush 37 is fixedly connected to the middle of the rotating shaft 34, and the sweeping brush 37 fits the interception filter 36. A powder return channel 38 is opened on the side of the dust suction pipe 31, and the powder return channel 38 is arranged on the side of the interception filter 36. The powder return channel 38 is connected to the top of the grinding bin 2 away from the dust suction pipe 31, and a connecting port 32 is provided on the bottom side of the dust suction pipe 31. During the dust suction process, the interception filter 36 in the dust suction pipe 31 will intercept the activated carbon powder. At this time, the third motor 33 will also drive the sweeping brush 37 to rotate. When the sweeping brush 37 rotates, it will sweep the activated carbon powder on the surface of the interception filter 36, and the swept activated carbon powder will be directly returned to the grinding bin 2 through the powder return channel 38 for the grinding process.

[0036] Specifically, the introduction of the dust-free component 3 can quickly recover the activated carbon powder in the air, significantly reduce the dust content in the air, protect the health of the staff, and reduce the loss of raw materials by recovering the activated carbon powder in the air, thereby reducing the production cost. The sweeping brush 37 design can automatically clean the interception filter, ensuring the long-term stable operation of the equipment and reducing the need for manual cleaning. At the same time, the cleaned activated carbon powder can quickly enter the subsequent production steps, thereby improving production efficiency.

[0037] Example 3

[0038] In the process of crushing activated carbon, larger activated carbon particles that do not reach the appropriate powder particle size will be produced. These activated carbon particles often need to be recovered first and then crushed for the second time, which is troublesome and requires a secondary crushing process, reducing production efficiency.

[0039] To further solve the above problems, refer to Figure 1 as well as Figure 6As shown, this embodiment provides a component structure that can quickly return and crush activated carbon particles that have reached a suitable particle size. A return component 4 is provided on one side of the crushing bin 1. The return component 4 includes a return box 41. The return box 41 is provided with a delivery port 42 and a recovery port 43 on the side close to the crushing bin 1. The delivery port 42 is connected to the return port 19, and the recovery port 43 is connected to the guide port 18. Activated carbon particles that have not reached a suitable particle size will enter the interior of the recovery port 43 through the guide port 18 of the crushing bin 1, and at the same time be sent back to the return port 19 through the delivery port 42.

[0040] In this embodiment, a first rotating shaft 44 and a second rotating shaft 45 are provided inside the return box 41, a transmission belt 47 is provided outside the first rotating shaft 44 and the second rotating shaft 45, a return shovel 48 is provided on the outer surface of the transmission belt 47, and a fourth motor 46 is provided outside the return box 41. The output shaft of the fourth motor 46 is fixedly connected to the central rotating shaft of the second rotating shaft 45. The activated carbon particles sieved out by the sieve plate 15 slide into the return box 41. The fourth motor 46 drives the second rotating shaft 45 to rotate. At this time, the second rotating shaft 45 will drive the transmission belt 47 to rotate, and the activated carbon particles entering the return box 41 will be scooped up by the return shovel 48 on the surface of the transmission belt 47, and then rotated and transmitted upward until they are transmitted to the position of the delivery outlet 42 to complete the return of materials.

[0041] Specifically, the design of the return component 4 can quickly recycle activated carbon particles that do not reach the appropriate particle size, avoiding the complicated operation of secondary crushing, improving the overall efficiency of the production line, and directly sending unqualified particles back to the crushing bin 1 through the return box 41, shortening the cycle time of material processing and improving production continuity. The return shovel 48 driven by the motor realizes automated return, reduces manual operation, and improves the intelligence level of the equipment.
