Description

Technical Field

[0001] The utility model relates to a special mould for producing activated carbon, and belongs to the technical field of structural design of moulds for producing activated carbon. Background Art

[0002] Activated carbon is a black porous solid carbon, which is made from coal raw materials through processes such as crushing, molding, carbonization, and activation. Activated carbon has a developed pore structure and a large surface area. It is easy to fully contact with toxic and harmful gases in the air and has a high adsorption efficiency for harmful gases. Therefore, it is widely used as an industrial adsorbent. The production of activated carbon usually requires the use of activated carbon production molds. The existing activated carbon production molds can only produce activated carbon with a circular radial cross-section. This shape of activated carbon has the following defects:

[0003] First, the external specific surface area is relatively small, and the adsorption effect is poor;

[0004] Second, during use, it is difficult for the adsorbed impurities to reach the core of the cylinder, and the utilization rate of activated carbon is low. Utility Model Content

[0005] In view of the above deficiencies in the prior art, the utility model provides a special mold for producing activated carbon, which can produce activated carbon with a radial cross-section in the shape of a clover, thereby improving the adsorption effect and utilization rate of the activated carbon.

[0006] The utility model discloses a special mold for producing activated carbon, comprising a mold base, wherein the mold base is penetrated with a plurality of mold installation holes along its axial direction, each mold installation hole is installed with a mold monomer, and each mold monomer is penetrated with a plurality of clover-shaped forming holes along its axial direction.

[0007] Furthermore, on the mold base, the mold mounting holes are evenly distributed in a circle with the center of the mold base as the center, and the position distribution of the mold mounting holes is relatively reasonable, which can effectively ensure the bearing strength of the mold mounting holes.

[0008] Furthermore, on the mold monomer, one of the forming holes is located at the center of the mold monomer, and the remaining forming holes are evenly distributed in a circle with the center of the mold monomer as the center. The position distribution of the forming holes is relatively reasonable, which can effectively ensure the bearing strength of the forming holes.

[0009] Furthermore, the mold mounting hole includes a mold monomer placement hole and a discharge hole which are connected to each other. The aperture of the mold monomer placement hole is larger than the aperture of the discharge hole. A step is formed between the mold monomer placement hole and the discharge hole. The mold monomer can be directly placed in the mold monomer placement hole and supported by the step, which is convenient for maintenance and replacement of the mold monomer.

[0010] Furthermore, the axial cross-section of the mold monomer placement hole is an isosceles trapezoid, and the axial cross-section of the mold monomer matching the mold monomer placement hole is also an isosceles trapezoid. On the one hand, it is convenient for stress dispersion and can effectively increase the service life of the mold monomer; on the other hand, the outer port aperture of the mold monomer placement hole is larger, making it more convenient to remove and insert the mold monomer.

[0011] Furthermore, the mold base is made of stainless steel, which can ensure the bearing strength of the mold base; the mold monomer is made of stainless steel or plastic material, which is easy to process and can effectively reduce production costs.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The special mold for producing activated carbon described in the utility model can produce activated carbon with a clover-shaped radial cross-section. Compared with traditional activated carbon with a circular radial cross-section, it has a larger external specific surface area and a better adsorption effect. In addition, the clover-shaped activated carbon can expose the core, which effectively improves the utilization rate of the activated carbon. BRIEF DESCRIPTION OF THE DRAWINGS
