Description

Technical Field

[0001] The present invention relates to the technical field of crushing processing, and particularly to a crusher for activated carbon processing. Background Art

[0002] Activated carbon is a functional adsorption material with a highly developed pore structure and a large specific surface area, playing a key role in many fields. In the environmental protection field, it is widely used in air purification, sewage treatment, etc., and can effectively remove harmful gases and pollutants; in the food industry, it can be used for food decolorization and purification; in chemical production, it participates in various chemical reactions as a catalyst carrier or adsorbent. With the continuous improvement of the performance requirements of activated carbon in various industries, its production and processing process also faces more stringent standards. The crushing link, as a key step in activated carbon processing, directly affects important indicators such as the particle size distribution, specific surface area, and adsorption performance of the product. Ideal activated carbon crushing should ensure that all raw materials can be fully crushed to an appropriate particle size to meet the needs of different application scenarios.

[0003] Currently, during the operation of existing crushers, a significant and urgent problem is that unfully crushed activated carbon will be discharged together with fully crushed activated carbon. This is because most existing crushing equipment lacks an effective particle size screening and separation mechanism. Take the hammer crusher as an example. When a large amount of activated carbon raw materials enter the crushing chamber, the impact of the hammer head will cause some raw materials to quickly reach the required particle size. However, there are still quite a number of larger particle-sized activated carbons that have only been partially crushed and do not meet the product requirements. Nevertheless, these unfully crushed activated carbons will mix with the fully crushed activated carbon along with the airflow and material flow in the crushing chamber and be discharged together from the discharge port.

[0004] This situation has various negative impacts on the production of activated carbon. From the perspective of product quality, the unfully crushed activated carbon particles are larger, with a relatively smaller specific surface area and much lower adsorption performance than fully crushed activated carbon, resulting in uneven quality of the entire batch of products. At the same time, the screening and treatment of unqualified products also require additional human, material, and time costs, further increasing the production cost.

[0005] Currently, the vast majority of existing crushers are not equipped with the function of reintroducing uncompletely crushed activated carbon back into the crusher for secondary crushing. This is mainly because the design of traditional crushers focuses on the one-time crushing efficiency and ignores the refined control of crushing quality. Moreover, even if some large particles are screened out, there is a lack of an effective conveying and reflux system to send them back to the crushing chamber for secondary treatment. Therefore, there is an urgent need to design a crusher for activated carbon processing to solve the above problems. Summary of the Invention

It also includes: a screening unit, which is arranged in the collecting box 101, and is used to screen the activated carbon discharged from the crushing box 102, discharge the activated carbon that meets the crushing requirements, and guide the activated carbon that is not completely crushed to the discharge hopper 111; a return unit, which is arranged on one side of the collecting box 101, and is used to collect the activated carbon discharged from the discharge hopper 111 and guide it back to the crushing box 102; a collecting unit, which is arranged in the collecting box 101, and is used to collect the activated carbon discharged into the collecting box 101.

[0031] The activated carbon to be crushed can be added to the crushing box 102 through the feeding frame 103. At this time, the driving motor 104 can drive the output wheel 105 to rotate. The output wheel 105 drives the transmission wheel 107 to rotate together through the belt 106, so that the crushing blades 109 outside the rotating shaft 108 rotate in the crushing box 102. Through the cooperation of the crushing blades 109 and the spacer 110, the crushing operation of the activated carbon can be realized. The crushed activated carbon will fall into the collection box 101.

When the activated carbon that is not completely crushed When discharged from the discharge hopper 111, it will directly fall into the collection hopper 302, and enter the lifting cylinder 303 along the collection hopper 302. The lifting cylinder 303 can be driven to move upward in the vertical cylinder 301 by the telescopic cylinder 1 305 until the top of the lifting cylinder 303 passes through the return port 309 and enters the return cover 308. At this time, the inclined top plate 307 can be driven upward by the telescopic cylinder 2 306, so that the activated carbon that is not fully crushed can be pushed out of the lifting cylinder 303 and enter the return cover 308, and then roll along the return cover 308 to the crushing box 102.

[0034] As an embodiment of the present invention, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 6 The collecting unit includes a lower hopper 401 fixedly arranged in the collecting box 101, a collecting tank 403 is placed in the collecting box 101, and a taking-in and putting-out port 402 is opened on the outer wall of one side of the collecting box 101 for taking-in and putting-in the collecting tank 403. The collecting tank 403 for collecting activated carbon can be placed in the collecting box 101 through the taking-in and putting-out port 402, and the fully crushed activated carbon will fall into the lower hopper 401 and be discharged into the collecting tank 403 through the lower hopper 401 to realize the automatic collection of the activated carbon, which is very convenient to use.

[0035] As an embodiment of the present invention, please refer to Figure 5 and Figure 6 , a movable rod 503 is movably arranged through the outer wall on one side of the collection box 101. A baffle 504 is fixedly arranged at one end of the movable rod 503, and a push plate 501 is fixedly installed at the other end of the movable rod 503. The push plate 501 is located in the collection box 101 and is in contact with the collection tank 403. A spring 505 is sleeved on the outer side of the movable rod 503.

A sealing plate 502 is fixedly installed at the top end of the push plate 501, and the sealing plate 502 is in contact with the bottom end of the feeding hopper 401. When the collection tank 403 is pushed into the collection box 101, the collection tank 403 will be in contact with the push plate 501 and drive the push plate 501 to move, so that the spring 505 on the outer side of the movable rod 503 is compressed, and the sealing plate 502 will move with the push plate 501 to release the blockage of the feeding hopper 401, so that the activated carbon in the feeding hopper 401 can fall into the collection tank 403. When the collection tank 403 is removed from the collection box 101 after collecting an appropriate amount of activated carbon, under the reset action of the spring 505, the push plate 501 can move with the collection tank 403, prompting the sealing plate 502 to block the bottom of the feeding hopper 401 before the collection tank 403 leaves the feeding hopper 401, which can effectively avoid the situation that the activated carbon directly falls to the bottom of the collection box 101 and is difficult to collect after the collection tank 403 is removed from the collection box 101, and the use effect is better.

[0036] As an embodiment of the present invention, please refer to Figure 5 and Figure 6 , a vertical plate 601 is fixedly installed on the inner wall of the bottom of the collection box 101, and the collection tank 403 is located between the vertical plates 601. An installation plate 602 is fixedly installed on the outer wall of the collection tank 403, and a clamping plate 603 is movably arranged through the outer wall of the installation plate 602.

The collection tank 403 can be placed between the vertical plates 601. When the collection tank 403 is completely moved below the feeding hopper 401, the grip rod 604 can be held to drive the clamping plate 603 to move, so that the clamping plate 603 is inserted into the clamping opening of the vertical plate 601, which can play a role in limiting the position of the collection tank 403 to prevent the collection tank 403 from being pushed outwards under the elastic force of the spring 505, and the use effect is better.

[0037] As an embodiment of the present invention, please refer to Figure 3 and Figure 7 ​, on one inner wall of the feeding frame 103, an inclined plate 701 is fixedly installed. A fixing hole is formed on the outer wall of the feeding frame 103, and a rotating rod 703 is rotatably connected in the fixing hole. An activity plate 702 is fixedly arranged on the outer wall of the rotating rod 703, and the activity plate 702 is located below the inclined plate 701. Baffles 705 are fixedly installed at both ends of the rotating rod 703. A torsion spring 704 is fixedly installed on the outer wall of the baffle 705 close to the feeding frame 103.

A limiting plate 706 is also fixedly arranged on one inner wall of the feeding frame 103, and the limiting plate 706 is located below the activity plate 702. The limiting plate 706 is used to limit the rotation amplitude of the activity plate 702 to prevent the activity plate 702 from contacting the rotating crushing blade 109. When the activated carbon to be crushed is added to the feeding frame 103, the gravity of the activated carbon can cause the activity plate 702 to rotate, and the torsion spring 704 is twisted, so that the activated carbon enters the crushing box 102 through the gap between the inclined plate 701 and the activity plate 702. After the activated carbon falls into the crushing box 102, the activity plate 702 can be reattached to the inclined plate 701 under the reset action of the torsion spring 704, which can automatically block the feeding frame 103, effectively preventing the activated carbon from splashing out through the feeding frame 103 during the crushing process, and the use effect is better.

[0038] During use, the activated carbon to be crushed can be added to the crushing box 102 through the feeding frame 103. At this time, the driving motor 104 can drive the output wheel 105 to rotate. The output wheel 105 causes the driving wheel 107 to rotate together through the belt 106, and then the crushing blade 109 outside the rotating shaft 108 rotates in the crushing box 102. Through the cooperation of the crushing blade 109 and the partition plate 110, the crushing operation of the activated carbon can be realized. The crushed activated carbon will fall into the collection box 101. Under the screening action of the screening unit, the activated carbon that meets the crushing requirements can be directly discharged downward, and the collection unit can collect the activated carbon that meets the crushing requirements. The activated carbon that is not completely crushed can be discharged through the discharge hopper 111 and re-introduced into the crushing box 102 through the return unit for secondary crushing until it meets the crushing requirements, effectively realizing the full crushing of the activated carbon, and the use effect is better.
