Specific embodiments

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will describe the embodiments of the present utility model in detail with reference to the attached drawings. However, the embodiments described in the present utility model are only a part of the embodiments of the present utility model, not all of the embodiments.

[0017] As Figures 1 to 3 shown, an activated carbon raw material crushing device includes: an upper housing 1, a lower housing 2, and a grinding disc 3.

[0018] The mounting pipe 11 is vertically provided at the top of the upper housing 1. The side wall of the mounting pipe 11 is communicated with the feeding pipe 12. The bottom of the upper housing 1 is provided with an upper conical hole 13 coaxial with the mounting pipe 11, and the apex of the upper conical hole 13 is communicated with the bottom of the mounting pipe 11.

[0019] The lower housing 2 is arranged on the bottom surface of the upper housing 1. The top of the lower housing 2 is provided with a lower conical hole 21 coaxial with the upper conical hole 13. The bottom of the lower conical hole 21 is arranged opposite to the bottom of the upper conical hole 13. The bottom of the lower housing 2 is provided with a discharge pipe 22 communicated with the apex of the lower conical hole 21. A support ring 23 is coaxially arranged inside the discharge pipe 22, and there is an annular gap between its outer wall and the inner wall of the discharge pipe 22.

[0020] The grinding disc 3 is in a vertically arranged spindle structure, which includes an upper cone 31 and a lower cone 32 arranged coaxially. The outer conical surface of the upper cone 31 and the inner wall of the upper conical hole 13 form a first crushing structure, and the outer conical surface of the lower cone 32 and the inner wall of the lower conical hole 21 form a second crushing structure; a transmission shaft 33 is coaxially arranged at the upper end of the grinding disc 3, which coaxially passes upward through the top of the installation pipe 11, and a motor 4 is arranged at the top of the installation pipe 11, and its main shaft is connected to the transmission shaft 33; a connecting shaft 34 is coaxially arranged at the lower end of the grinding disc 3, which passes through the support ring 23 to ensure the stability of the grinding disc 3 during rotation.

[0021] The distance between the outer conical surface of the upper cone 31 and the inner wall of the upper conical hole 13 is greater than the distance between the outer conical surface of the lower cone 32 and the inner wall of the lower conical hole 21.

[0022] During crushing, the raw materials for preparing activated carbon are put into the upper shell 1 from the feeding pipe 12. The raw materials will quickly fall from the apex of the upper cone 31 into the first crushing structure for the first crushing. During the process of the raw materials falling into the first crushing structure, the grinding disc 3 rotates continuously driven by the motor 4, which can make the raw materials more evenly distributed at various places on the circumference of the upper cone 31, thereby improving the crushing effect; after the raw materials pass through the first crushing structure, they will automatically fall into the second crushing structure for the second crushing. After the crushing is completed, the materials can automatically discharge downward from the annular space between the support ring 23 and the discharge pipe 22; because the distance between the outer conical surface of the upper cone 31 and the inner wall of the upper conical hole 13 is greater than the distance between the outer conical surface of the lower cone 32 and the inner wall of the lower conical hole 21, the raw materials are roughly crushed in the first crushing structure, and will be further refined in the second crushing structure, and the uniformity of the crushing particle size is improved, so as to improve the crushing effect and efficiency.

[0023] Preferably, as Figure 2 、 Figure 3 shown, both the lower end of the upper conical hole 13 and the upper end of the lower conical hole 21 have cylindrical holes arranged coaxially and with the same inner diameter. There is a cylinder 35 between the upper cone 31 and the lower cone 32, and a third crushing structure is formed between the outer wall of the cylinder 35 and the inner walls of the cylindrical holes of the upper conical hole 13 and the lower conical hole 21; and the distance between the cylinder 35 and the cylindrical hole is less than the distance between the outer conical surface of the upper cone 31 and the inner wall of the upper conical hole 13, and greater than the distance between the outer conical surface of the lower cone 32 and the inner wall of the lower conical hole 21, so that the raw materials are gradually crushed and refined by the first crushing structure, the second crushing structure and the third crushing structure, further improving the uniformity of the crushing particle size and the crushing efficiency.

[0024] Preferably, as Figure 2 shown, the upper shell 1 and the lower shell 2 are connected by bolts for easy assembly and maintenance.

[0025] Preferably, as Figure 2 、 Figure 3As shown, a support spring 5 is sleeved on the connecting shaft 34, and it is located between the lower cone 32 and the support ring 23. When the support spring 5 is in the natural support state, the distance between the outer conical surface of the upper cone 31 and the inner wall of the upper conical hole 13 is greater than the distance between the outer conical surface of the lower cone 32 and the inner wall of the lower conical hole 21. The grinding disc 3 is arranged to move along the axis. In this way, while the grinding disc 3 rotates to crush the material, it can impact the material by moving up and down to improve the efficiency of crushing the material. The driving force for the grinding disc 3 to move along the axis comes from the reaction force generated on the grinding disc 3 when the material is squeezed and crushed. The component force of this reaction force in the axial direction of the grinding disc 3 will compress the support spring 5. After the material is crushed, its volume becomes smaller, the reaction force will decrease, and the support spring 5 will also use its own elastic force to move the grinding disc 3 upward to drive the grinding disc 3 to move along the axis. For the setting of the motor 4, multiple guide rods can be arranged on the top surface of the installation pipe 11, and the guide rods pass through the installation flange of the motor 4, so that the motor 4 can move along the guide rods, and the rotation of the motor 4 is restricted by the guide rods. In this way, the motor 4 can move along the axis together with the grinding disc 3.

[0026] Further preferably, as Figures 1 to 3 shown, multiple support rods 14 are provided at the top of the installation pipe 11 for installing the motor 4. A spline sleeve 41 is coaxially provided on the main shaft of the motor 4. The upper end of the transmission shaft 33 is a spline shaft structure, and the spline shaft is fitted in the spline sleeve 41 to meet the requirement of the grinding disc 3 moving along the axis, and at the same time, the motor 4 is used to drive the grinding disc 3 to rotate.

[0027] Further preferably, as Figure 2 shown, a thrust bearing 51 is provided between the support spring 5 and the support ring 23 to reduce the friction between the support spring 5 and the support ring 23, reduce the wear between parts, and extend the service life of the device.

[0028] Preferably, convex strips are provided on the outer walls of both the upper cone 31 and the lower cone 32, and strip-shaped grooves are provided on the inner walls of both the upper conical hole 13 and the lower conical hole 21 to improve the crushing effect by using the convex strips and the strip-shaped grooves.

[0029] The above are only the preferred embodiments of the present invention, and do not represent the only or limit the present invention. Those skilled in the art should understand that without departing from the scope of the present invention, various changes or equivalent replacements made to the present invention all fall within the scope of protection of the present invention.
