Description

Technical Field

[0001] The present invention relates to the field of screening technology, in particular to an activated carbon grading crushing and screening device and a process thereof. Background Art

[0002] In the activated carbon industry, the yield of activated carbon crushed to a particle size of 80-325 mesh has long been a key issue plaguing the industry. Currently, the overall yield is only around 40-60%. When the proportion of particles in the 200-325 mesh range is excessive, the yield is even lower, and the carbon also contains high levels of dust. This not only wastes resources and increases production costs, but also reduces product quality and stability.

[0003] Furthermore, most existing crushing systems use mechanical conveying, which generates a large amount of dust during the production process. This dust not only affects the working environment in the production workshop and poses a threat to the health of operators, but also has a negative impact on the surrounding environment, failing to meet increasingly stringent environmental protection requirements. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an activated carbon grading crushing and screening device and a process thereof.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An activated carbon graded crushing and screening device is designed, comprising an equipment mounting frame, on which a first square high-grade screen and a second square high-grade screen are mounted. A multi-stage crushing device is disposed at the bottom of the equipment mounting frame, and the devices are connected via sealed pipes, which are connected to a negative pressure system.

[0007] Preferably, the first square high-grade screening machine and the second square high-grade screening machine are connected to a dust removal unit through a pipeline, and the dust removal unit is connected to a motor through a pipeline.

[0008] Preferably, the dust removal unit includes a cyclone dust collector and a cyclone dust filter, and the cyclone dust collector and the cyclone dust filter are located between the first square high-grade screening machine and the motor.

[0010] The present invention also provides a crushing and screening process of a carbon grading crushing and screening device, which specifically includes the following steps:

[0011] S1. Primary crushing: The activated carbon raw material with a particle size of 20-80 mesh is fed into the first crusher for the first crushing, so that it is broken into activated carbon particles of 60-80 mesh. In this process, the rollers of the first crusher rotate at a specific differential speed, and through extrusion and shearing, the larger particles of activated carbon are broken into the appropriate particle size range;

[0012] S2, secondary crushing: The 60-80 mesh activated carbon particles obtained after the primary crushing are sent to the second crusher for a second crushing, so that they are further crushed into 80-100 mesh activated carbon particles. Similarly, the special effect of the differential speed roller is used to ensure the stability and uniformity of the crushing effect;

[0013] S3, tertiary crushing: The 80-100 mesh activated carbon particles obtained after the secondary crushing are subjected to the third crusher to be finally crushed into 100-325 mesh activated carbon particles. Through these three stages of crushing, the activated carbon particle size is gradually refined, and the yield within a specific particle size range is improved;

[0014] S4. Use sealed pipes to connect each crushing link and between the crushing equipment and subsequent processing equipment, and use fans and other equipment to create a negative pressure environment in the pipes;

[0015] S5. Cyclone dust collectors and cyclone dust filters are installed at key locations of crushing equipment and conveying pipelines. The cyclone dust collectors and cyclone dust filters are connected to the negative pressure system, which can collect the dust generated during the production process in time and effectively reduce the dust concentration in the workshop.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-2 An activated carbon graded crushing and screening device includes an equipment mounting frame, on which a first square high-grade screen 4 and a second square high-grade screen 5 are installed. A multi-stage crushing device is installed at the bottom of the equipment mounting frame, and the devices are connected through sealed pipes, which are connected to a negative pressure system.

[0022] The first square high-grade screening machine 4 and the second square high-grade screening machine 5 are connected to a dust removal unit through a pipeline, and the dust removal unit is connected to the motor 1 through a pipeline.

[0023] The dust removal unit includes a cyclone dust collector 2 and a cyclone dust filter 3 , and the cyclone dust collector 2 and the cyclone dust filter 3 are located between the first square high-grade screening machine 4 and the motor 1 .

[0024] The multi-stage crushing equipment consists of a first crusher 6, a second crusher 7 and a third crusher 8. The first crusher 6, the second square high-grade screen 5, the second crusher 7, the second square high-grade screen 5 and the third crusher 8 are connected in sequence through pipelines.

[0025] A crushing and screening process of an activated carbon graded crushing and screening device specifically comprises the following steps:

[0026] S1, primary crushing: The activated carbon raw material with a particle size of 20-80 mesh is fed into the first crusher 6 for the first crushing, so that it is crushed into activated carbon particles of 60-80 mesh. In this process, the rollers of the first crusher 6 rotate at a specific differential speed, and through the extrusion and shearing action, the larger particles of activated carbon are crushed into the appropriate particle size range;

[0027] S2, secondary crushing: The 60-80 mesh activated carbon particles obtained after the primary crushing are sent to the second crusher 7 for a second crushing, so that they are further crushed into 80-100 mesh activated carbon particles. Similarly, the special effect of the differential speed roller is used to ensure the stability and uniformity of the crushing effect;

[0028] S3, tertiary crushing: The 80-100 mesh activated carbon particles obtained after the secondary crushing are subjected to the third crusher 8 to be finally crushed into 100-325 mesh activated carbon particles. Through these three stages of crushing, the activated carbon particle size is gradually refined, and the yield within a specific particle size range is improved;

[0029] After each stage of the crusher crushes the activated carbon particles, the material is transferred through a pipeline to a matching screening machine for screening.

[0030] Final screening: Activated carbon below 220 mesh enters the round sieve for screening to obtain activated carbon particles above 325 mesh.

[0031] Finally, activated carbon particles with different particle size ranges of 80-100 mesh, 100-150 mesh, 150-220 mesh, and 220-325 mesh are formed. Through reasonable proportioning, activated carbon with a particle size of 80-325 mesh with different particle size proportions can be formed.

[0032] S4. Use sealed pipes to connect each crushing link and between the crushing equipment and subsequent processing equipment, and use fans and other equipment to create a negative pressure environment in the pipes;

[0033] S5. Cyclone dust collectors 2 and cyclone dust filters 3 are installed at key locations of the crushing equipment and conveying pipelines. The cyclone dust collectors 2 and cyclone dust filters 3 are connected to the negative pressure system, which can collect the dust generated during the production process in time and effectively reduce the dust concentration in the workshop.

[0034] Gradual screening process: Five-sieve, six-mesh screening uses five sieves and six different meshes to screen activated carbon particles of varying sizes, ranging from 80-325 mesh. The different mesh sizes allow for precise screening based on particle size, ensuring that particles within each size range are accurately separated.

[0035] Negative pressure conveying and dust removal process

[0036] In order to solve the dust problem during the production process, negative pressure conveying and negative pressure dust removal technology are used throughout the production process. The specific settings are as follows:

[0037] 1. Negative pressure transportation: Sealed pipes are used to connect each crushing link and between the crushing equipment and subsequent processing equipment, and a negative pressure environment is formed in the pipes through fans and other equipment. In this way, the activated carbon particles can be stably adsorbed in the pipes during the transportation process, avoiding dust generated by leakage.

[0038] 2. Negative pressure dust removal: Cyclone dust collector 2 and cyclone dust filter 3 are installed at key positions of crushing equipment and conveying pipelines. Cyclone dust collector 2 and cyclone dust filter 3 are connected to the negative pressure system, which can collect the dust generated in the production process in time and effectively reduce the dust concentration in the workshop.

[0039] The effect achieved:

[0040] 1. Improve the yield: Through the three-stage crushing process and the special crushing effect of the differential roller crusher, the crushing particle size of the activated carbon can be accurately controlled, so that the yield of 80-325 mesh activated carbon reaches more than 85-90%, which significantly improves the production efficiency and resource utilization and reduces the production cost.

[0041] 2. Optimize particle size distribution: The proportion of activated carbon particles with a size of 80-200 meshes reaches more than 85%, meeting the market demand for activated carbon with a specific particle size and improving product quality and market competitiveness.

[0042] 3. Environmental protection and energy saving: The use of negative pressure conveying and negative pressure dust removal technology effectively solves the dust problem in the production process, improves the working environment of the production workshop, reduces pollution to the surrounding environment, and meets environmental protection requirements. At the same time, the rational design of the negative pressure system can also reduce energy consumption and achieve the goal of energy conservation and emission reduction.

[0043] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
