Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon preparation equipment, in particular to a raw material crushing device for activated carbon preparation. Background Art

[0002] Activated carbon is a specially treated carbon. Organic raw materials (fruit shells, coal, wood, etc.) are heated in an airtight condition to reduce non-carbon components (this process is called carbonization). Then it reacts with gas, the surface is corroded, and a microporous structure is produced (this process is called activation). Since the activation process is a microscopic process, that is, the surface corrosion of a large number of molecular carbides is point corrosion, the surface of the activated carbon has countless tiny pores.

[0003] The traditional activated carbon raw material crushing device does not have the function of secondary crushing of the activated carbon raw materials. The one-time crushing has the defect of incomplete and incomplete crushing. In addition, dust and waste will be generated when the activated carbon raw materials are crushed. The dust and waste are not discharged, resulting in dust and waste falling into the crushing device. Dust and waste are accumulated for a long time, affecting the use of the crushing device.

[0004] In order to solve the above problems, a patent document with publication number "CN218690359U" discloses a raw material crushing device for preparing activated carbon, including a crushing box, the top of which is connected to an inlet bucket, a crushing motor is fixedly installed on the front of the crushing box, and the output end of the crushing motor extends to the interior of the crushing box.

[0005] In the above-mentioned prior art, since the activated carbon raw material is in irregular granular shape after crushing, it is easy to get stuck in the sieve holes when the (sieve plate) is screening the crushed raw material particles, causing the sieve holes to be blocked, affecting the screening operation. At the same time, during screening, since the sieve plate (or screen) exists inside the device, it is not convenient for personnel to clean it; at the same time, if the raw material particles after the first crushing are only slightly larger in diameter, after the second crushing, it is very likely to produce raw material particles with a diameter that is too small (or produce more powder), which cannot meet the crushing requirements and is prone to waste of raw materials. Therefore, a raw material crushing device for preparing activated carbon is needed. Utility Model Content

In addition, a feeding hopper is arranged above the device housing 1, and a collecting frame for collecting crushed raw material particles is arranged below;

[0026] A movable screen 3 is installed in the housing 1 of the device, and a driving member for driving the movable screen 3 to perform a circular motion up and down and left and right is installed on one side of the movable screen 3. The driving assembly 5 is connected to the driving member through a transmission assembly.

[0027] A fixed screen 7 is arranged on the upper end of the movable screen 3 , and the fixed screen 7 is fixed to the inner side of the device housing 1 . When the movable screen 3 moves to the highest point, it fits with the bottom surface of the fixed screen 7 .

[0028] Based on the above structure, after the activated carbon raw material is crushed by the crushing roller 2, the raw material particles fall downward into the fixed screen 7, part of the raw material passes through the fixed screen 7 and continues to move downward, and finally falls on the movable screen 3 and is screened again by the movable screen, and the raw material particles that meet the size fall into the collection frame below and are collected, while the raw material particles that do not meet the size are intercepted by the fixed screen 7 and the movable screen 3, and slide along the fixed screen 7 and the movable screen 3 into the feeding component 4, and are lifted by the feeding component to the top of the crushing roller 2 for secondary crushing;

[0029] During this process, when the movable screen 3 moves to the highest point, it fits with the bottom surface of the fixed screen 7, so that the movable screen 3 and the fixed screen 7 cooperate to produce a shearing effect, and the raw material particles stuck in the fixed screen 7 or above the movable screen 3 are sheared and crushed, so that the raw material particles become smaller and pass through the fixed screen 7 or the movable screen 3 smoothly, so as to achieve the purpose of smooth material discharge, avoid irregular raw material particles clogging the screen, and at the same time reduce the number of particles that do not meet the requirements, reduce the number of raw material particles that are crushed for the second time, avoid multiple crushing to produce more powder, and reduce raw material loss.

[0030] Furthermore, the driving member includes an eccentric cam 8 and a connecting shaft 10.

[0034] By setting the transmission wheel 11 and the transmission belt 12, the power of the driving component 5 can be transmitted to the eccentric cam 8 to drive the eccentric cam 8 to rotate, so as to achieve the effect of simultaneously driving the crushing roller 2 and the movable screen 3 with the same power source, thereby reducing the setting of the power source, saving energy and reducing the equipment cost.

[0035] Furthermore, the aperture of the fixed screen 7 is larger than the aperture of the movable screen 3 , and the maximum distance between the fixed screen 7 and the movable screen 3 is smaller than the aperture of the movable screen 3 .

[0036] By setting the aperture of the fixed screen 7 to be larger than the aperture of the movable screen 3, the fixed screen 7 and the movable screen 3 can cooperate to achieve the effect of secondary screening, and the screening is more effective; at the same time, it is also convenient for the movable screen 3 to perform secondary crushing of larger raw material particles (smaller than the aperture of the fixed screen 7 and larger than the aperture of the movable screen 3).

[0039] Working principle of the utility model: in daily use, after the activated carbon raw material is crushed by the crushing roller 2, the raw material particles fall downward into the fixed screen 7, part of the raw material passes through the fixed screen 7 and continues to move downward, and finally falls on the movable screen 3 and is screened again by the movable screen, and the raw material particles that meet the size fall into the collection frame below and are collected, while the raw material particles that do not meet the size are intercepted by the fixed screen 7 and the movable screen 3, and slide along the fixed screen 7 and the movable screen 3 into the feeding component 4, and are lifted by the feeding component to the top of the crushing roller 2 for secondary crushing;

[0040] During this process, when the movable screen 3 moves to the highest point, it fits with the bottom surface of the fixed screen 7, so that the movable screen 3 and the fixed screen 7 cooperate to produce a shearing effect, and the raw material particles stuck in the fixed screen 7 or above the movable screen 3 are sheared and crushed, so that the raw material particles become smaller and pass through the fixed screen 7 or the movable screen 3 smoothly, so as to achieve the purpose of smooth material discharge, avoid irregular raw material particles clogging the screen, and at the same time reduce the number of particles that do not meet the requirements, reduce the number of raw material particles that are crushed for the second time, avoid multiple crushing to produce more powder, and reduce raw material loss.
