Description

Technical Field

[0001] The utility model relates to the technical field of pulverization, in particular to a raw material pulverization device that can be used for the production of activated carbon. Background Art

[0002] Activated carbon is produced from a wide variety of raw materials, including wood, sawdust, fruit shells, anthracite, bituminous coal, and lignite. To process these raw materials into activated carbon, they must be pulverized. This pulverization process reduces particle size and increases specific surface area. In the activated carbon production process, a larger specific surface area improves its adsorption properties. Pulverization allows the raw materials to come into contact with the activating agent during subsequent processes such as activation, creating a more porous structure and thus enhancing the activated carbon's adsorption capacity.

[0003] Currently, there are many types of raw material crushing equipment available in the prior art. For example, a Chinese patent with publication number CN116673095A discloses a crushing device for preparing activated carbon using coconut shells as raw materials. The device comprises a crushing tank with a crushing inlet on its upper side, a conveyor belt disposed within its lower end, a coarse crushing assembly and a fine crushing assembly disposed within the crushing tank, the coarse crushing assembly and the fine crushing assembly being located between the crushing inlet and the conveyor belt, with the fine crushing assembly located below the coarse crushing assembly. Furthermore, a heating resistor is disposed within the crushing tank. When using the crushing device provided by the patent, coconut shells are introduced into the crushing inlet and crushed by both the coarse crushing assembly and the fine crushing assembly, ensuring a high crushing efficiency. The crushed coconut shells fall onto the conveyor belt and are carried away from the crushing tank by the conveyor belt, reducing the labor required to collect the finished raw material. Furthermore, as the coarse crushing assembly and the fine crushing assembly crush the coconut shells, the heating resistor heats the crushing tank, drying the crushed coconut shells and preventing residual moisture from affecting the processing efficiency of the activated carbon during production.

[0004] From the technical solution disclosed in the above patent, it can be seen that the crushing equipment mainly crushes coconut shells by squeezing, hammering, etc., and coconut shells are relatively hard in texture and have a certain toughness and strength. Simple squeezing is usually difficult to crush coconut shells because the shape and structure of coconut shells can disperse the squeezing force to a certain extent. When hammering coconut shells, although they can be crushed under a certain force, it is not easy to do so. This is because coconut shells contain rich fiber tissue and have a relatively compact structure. Therefore, if you want to crush coconut shells using the equipment provided by the above patent, you need to apply a large force to the coconut shells, or repeat the crushing process on the coconut shells, which increases the crushing cost or reduces the efficiency of coconut shell crushing.

For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components.

[0027] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0028] Example 1

[0029] To rapidly process activated carbon raw material powder, this embodiment proposes a novel pulverizing device. This device performs a two-stage shredding process on activated carbon raw materials, such as coconut shells. This shredding process utilizes tearing forces to break the raw materials into the desired size, avoiding the need for prolonged or repeated squeezing and impact that can affect pulverization efficiency. Furthermore, the pulverized material lands on a conveyor for transport to the next process. The detailed technical solution is described below.

[0030] like Figure 1 、 Figure 2 As shown, specifically, the device includes a belt conveyor 1, a filter assembly 3, a first crushing assembly 2, and a second crushing assembly 4. The filter assembly 3, the first crushing assembly 2, and the second crushing assembly 4 are all arranged above the belt conveyor 1, and the first crushing assembly 2, the filter assembly 3, and the second crushing assembly 4 are arranged in sequence along the length direction of the belt conveyor 1. Specifically, the activated carbon raw material is first processed by the first crushing assembly 2 and then filtered by the filter assembly 3. Qualified materials fall onto the belt conveyor 1, and unqualified materials move to the second crushing assembly 4. Qualified materials obtained by further processing by the second crushing assembly 4 still fall onto the belt conveyor 1. The materials are broken by tearing in the first crushing assembly 2, which can offset the current situation of coconut shell deformation, tight structure, and other difficulties in crushing, providing support for the faster completion of batch activated carbon material crushing.

[0031] like Figure 3 As shown, in order to tear activated carbon raw materials such as coconut shells through the first crushing component 2, the first crushing component 2 includes a hopper 23, two side plates 22 and an end plate 21. The two side plates 22 and the end plate 21 are spliced to form a frame with openings on the top and bottom, which provides space for the installation of the crushing mechanism inside and limits the position of the material. In addition, the hopper 23 is also arranged above the frame, and the material can be directly put into the frame through the hopper 23, and then the material can be torn through the crushing mechanism.

[0032] like Figure 3 、 Figure 8 As shown, a first-stage shredder 25 and a second-stage shredder 24 are disposed on the inner side of the frame. The first-stage shredder 25 is positioned above the second-stage shredder 24. Specifically, the shredders include a blade shaft and hook-type shredder blades, each of which is uniformly mounted on the blade shaft. Each shredder includes at least one set of hook-type shredder blades mounted on the blade shaft. If only one set of hook-type shredder blades is provided, a fixed blade is mounted on the side wall of the frame to cooperate with the rotating hook-type shredder blades to tear the material. If two sets of hook-type shredder blades are provided, the two sets of hook-type shredder blades must rotate in opposite directions to tear the material. The specific installation method can be determined based on actual needs; the goal is to tear the material. Furthermore, when the first-stage shredder 25 and the second-stage shredder 24 are installed, each can be equipped with a motor, or they can share a single motor. If they share a single motor, the motors are connected to the first-stage shredder 25 and the second-stage shredder 24 using existing connection methods such as gears and sprockets.

[0033] When installing the first-stage shredder 25 and the second-stage shredder 24, attention should be paid to their shredding degree. It is best if the second-stage shredder 24 tears finer than the first-stage shredder 25, so as to facilitate the crushing of activated carbon materials such as coconut shells into the required size.

[0034] like Figure 3 As shown, to limit the movement of material within the frame, a guide plate 26 is provided on the inside of the frame. Four guide plates 26 are provided, each divided into two groups. The two guide plates 26 in one group are arranged in an inverted "eight" pattern. The two groups of guide plates 26 are respectively provided below the first-stage shredder 25 and the second-stage shredder 24. The cooperation of the upper and lower groups of guide plates 26 allows the shredded material of the first-stage shredder 25 and the second-stage shredder 24 to be discharged from the lower end of the frame. To enable the material to move from the first shredder assembly 2 to the filter assembly 3, a discharge pipe is provided below the first shredder assembly 2, the lower end of which extends into the upper end of the filter assembly 3.

[0035] like Figure 4 、 Figure 5As shown, in order to achieve the screening of the primary crushed material, the filter assembly 3 includes a filter cartridge 31 and multiple rollers 34. Both ends of the filter cartridge 31 are sleeved with an annular plate 32. The multiple rollers 34 are hingedly arranged on a connecting frame 33. The connecting frame 33 is distributed on the upper and lower sides of the filter cartridge 31 and is connected to the frame (which also supports the first crushing assembly 2 and the second crushing assembly 4). In addition, the rollers 34 are arranged on the inner side of the two annular plates 32. Therefore, under the action of the rollers 34, the filter cartridge 31 can be rotatably arranged on the frame. In addition, a motor is provided at the end of the filter cartridge 31. The motor is connected to the end of the filter cartridge 31 through a sprocket and chain 35. Then, under the operation of the motor, the filter cartridge 31 rotates, accelerating the screening of the material. During the screening process, the material that meets the requirements passes through the side wall of the filter cartridge 31 and falls onto the belt conveyor 1, and the material can be transported to the next process.

[0036] Example 2

[0037] like Figure 6 、 Figure 7 As shown, on the basis of Example 1, the fragments that are still large after being processed by the first crushing component 2 need to be crushed again after screening, so that the coconut shell and other raw materials can be crushed quickly and efficiently. Therefore, the material remaining in the filter cylinder 31 after screening moves downward along the inclined direction of the filter cylinder 31 and falls on the second crushing component 4. In order to crush the material into corresponding sizes through the second crushing component 4, the second crushing component 4 includes a bin body 41 and a crushing rotor 42. A support frame 43 is provided on the bin body 41, and the support frame 43 is connected to the frame body. The crushing rotor 42 is arranged on the inner side of the bin body 41, which includes a main shaft, a disc, and a blade. The disc is installed on the main shaft, and the blade is installed on the disc. A motor is provided on the outside of the bin body 41, and the motor controls the rotation of the crushing rotor 42. Therefore, when the motor is working, the blade rotates at high speed, thereby crushing the material again. A filter screen 44 is provided at the discharge end at the bottom of the silo 41 , and the filter screen 44 can filter the material so that the material that meets the size falls to the belt conveyor 1 , while the material that does not meet the size remains in the silo 41 and continues to be crushed under the action of the blade.

[0038] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
