Description

Technical Field

[0001] The utility model relates to the technical field of equipment for activated carbon production, and specifically refers to a crushing mechanism for a material crushing and screening device used in activated carbon production. Background Art

[0002] During the production process of activated carbon, two activation processes are required. After the materials are activated in a primary activation furnace, they are sent to a secondary activation furnace for secondary activation after being crushed and screened by a corresponding crushing and screening device.

[0003] Existing material crushing and screening devices for activated carbon production generally include an independently arranged material crushing device and a material screening device. After the crushing is completed, the materials are directly put into the material screening device for screening. In the actual operation of such a material crushing and screening device, there is a big problem: the materials are directly screened after the first crushing, resulting in incomplete crushing of the materials. In response to this problem, the existing method is to collect the screened materials and perform secondary or even multiple crushing and then screening, resulting in low production efficiency, and the continuous turnover of the materials will also greatly increase the labor intensity of relevant operators.

[0004] Therefore, the research purpose of the present utility model is to design a crushing mechanism for a material crushing and screening device for activated carbon production that can effectively perform cyclic crushing operations on materials to ensure the crushing effect of the materials; and can perform crushing and screening simultaneously to prevent the crushed materials from being mixed in the pile of materials to be crushed and affecting the crushing process, thereby further ensuring the crushing effect of the materials. Summary of the Invention

[0005] In view of the above technical problems existing in the prior art, the present utility model provides a crushing mechanism for a material crushing and screening device for activated carbon production, which can effectively solve the above technical problems existing in the prior art.

[0006] The technical solution of the present utility model is as follows:

[0007] A crushing mechanism for a material crushing and screening device for activated carbon production, comprising:

[0008] A crushing tank, a feeding hopper is arranged at the top of the crushing tank, the bottom of the crushing tank is spherical and is evenly distributed with a plurality of corresponding first filtering holes, a corresponding lifting pipe is rotatably installed in the crushing tank, a driving shaft installed with a spiral feeding plate is rotatably arranged in the lifting pipe, the center of the bottom of the crushing tank is concave and is connected downward with a corresponding discharge pipe, and a corresponding discharge valve is fixedly installed on the discharge pipe;

[0009] A crushing material pressing piece is spherically arranged and fixedly connected to the material lifting pipe, the bottom side of the crushing material pressing piece is spaced apart from the bottom of the crushing material tank, and a plurality of corresponding discharge holes are evenly distributed on the material lifting pipe on the upper side of the crushing material pressing piece;

[0010] The material lifting drive mechanism is arranged on the top of the crushing tank and is used to drive the drive shaft and the material lifting pipe to rotate synchronously in opposite directions.

[0011] The material lifting drive mechanism includes a driving motor for rotating the driving shaft and a driven shaft for rotating the material lifting tube. The top of the driven shaft is connected to the output shaft end of the driving motor through a belt drive, and the bottom of the driven shaft is connected to the material lifting tube through a gear meshing drive.

[0012] The bottom side of the crushing tank is sleeved in the corresponding screening box, and the material filtered through the first filter holes is discharged and collected along the discharge pipe of the screening box, and the material not filtered through the first filter holes is discharged and collected along the discharge pipe.

[0013] The bottom side surface of the screening box is arranged in an inclined shape, and the discharge pipe is connected to the lowest end of the bottom side surface of the screening box.

[0014] The screening box is fixedly mounted on the corresponding frame through corresponding coil springs.

[0015] The crushing tank is fixedly mounted on the frame via a corresponding fixing plate.

[0016] The crushed material pressing piece is hollow, and the hollow part of the crushed material pressing piece is filled with a plurality of corresponding damping particles for vibration reduction.

[0017] The vibration reduction damping particles are spherical particles made of polymer materials.

[0018] Advantages of the utility model:

[0019] 1) Driven by the material lifting drive mechanism of the present utility model, the drive shaft and the material lifting pipe rotate synchronously in opposite directions, thereby driving the crushing and pressing member to grind and crush the material entering between the crushing tank and the crushing and pressing member. During the crushing process, the material with a qualified particle size is screened out through the first filter holes, and the material that has not been crushed sufficiently is lifted upward by the drive shaft equipped with a spiral feeding plate and then falls back between the crushing tank and the crushing and pressing member to continue the grinding and crushing process. As the grinding and crushing of the material continues, it is only necessary to periodically control the opening of the discharge valve to discharge the slag stored at the bottom of the crushing tank. Thus, the crushing operation of the material can be effectively cycled to ensure the crushing effect of the material; and it can achieve crushing and screening simultaneously to prevent the crushed material from being mixed in the material pile to be crushed, thereby further ensuring the crushing effect of the material.

[0020] 2) The material lifting drive mechanism of the present utility model includes a drive motor for driving the drive shaft to rotate and a driven shaft for driving the material lifting pipe to rotate. The top of the driven shaft is connected to the output shaft end of the drive motor through a belt drive, and the bottom of the driven shaft is connected to the material lifting pipe through a gear meshing drive, so as to realize the synchronous reverse rotation drive of the drive shaft and the material lifting pipe with the intervention of a set of drive motors, thereby effectively ensuring the practical effect of the present utility model.

[0021] 3) The hollow part of the crushing and pressing member of the present utility model is filled with many damping particles made of polymer materials for vibration reduction. It can not only reduce the overall weight of the crushing and pressing member, but also significantly reduce the vibration generated by the crushing and pressing member when grinding and crushing the material under the friction energy dissipation of the damping particles for vibration reduction, thereby improving the crushing effect of the material and effectively maintaining the stability of the overall mechanism of the present utility model.

[0029] The scrap material tank 1, a feed hopper 101 is arranged at the top of the scrap material tank 1, the bottom of the scrap material tank 1 is arranged in a spherical shape and is evenly distributed with a plurality of corresponding first filter holes 2, a corresponding material lifting pipe 3 is rotatably installed in the scrap material tank 1, a drive shaft 5 installed with a spiral feeding plate 4 is rotatably arranged in the material lifting pipe 3, the bottom center of the scrap material tank 1 is recessed and is connected downward with a corresponding discharge pipe 102, and a corresponding discharge valve 6 is fixedly installed on the discharge pipe 102;

[0030] The scrap material pressing part 7 is arranged in a spherical shape and is fixedly connected to the material lifting pipe 3, there is a gap between the bottom side of the scrap material pressing part 7 and the bottom of the scrap material tank 1, and a plurality of corresponding discharge holes 301 are evenly distributed on the material lifting pipe 3 on the upper side of the scrap material pressing part 7;

[0031] The material lifting drive mechanism 8 is arranged at the top of the scrap material tank 1 and is used to drive the drive shaft 5 and the material lifting pipe 3 to rotate synchronously and in opposite directions.

[0032] Driven by the material lifting drive mechanism 8, the drive shaft 5 and the material lifting pipe 3 rotate synchronously and in opposite directions, thereby driving the scrap material pressing part 7 to grind and crush the material entering between the scrap material tank 1 and the scrap material pressing part 7. During the crushing process, the material with a qualified particle size is screened out through the first filter holes 2, and the material that has not been crushed in place is lifted upward by the drive shaft 5 installed with the spiral feeding plate 4 and then falls back between the scrap material tank 1 and the scrap material pressing part 7 to continue the grinding and crushing process. As the grinding and crushing of the material continues, it is only necessary to regularly control the opening of the discharge valve 6 to discharge the slag stored at the bottom of the scrap material tank 1. Thus, the crushing operation of the material can be effectively cycled to ensure the crushing effect of the material; and it can realize crushing and screening at the same time to prevent the crushed material from being mixed in the material pile to be crushed and affecting the crushing process, thereby further ensuring the crushing effect of the material.

[0033] The material lifting drive mechanism 8 includes a driving motor 801 for rotating the driving shaft 5, and a driven shaft 802 for rotating the material lifting tube 3. The top of the driven shaft 802 is connected to the output shaft end of the driving motor 801 through a belt drive, and the bottom of the driven shaft 802 is connected to the material lifting tube 3 through a gear meshing drive.

[0034] During use, the driving motor 801 drives the driving shaft 5 and the driven shaft 802 to form a forward rotation, while the lifting tube 3 forms a reverse rotation opposite to the rotation direction of the driving shaft 5, so as to realize the synchronous reverse rotation drive of the driving shaft 5 and the lifting tube 3 under the intervention of a set of driving motors 801, thereby effectively ensuring the practical effect of the utility model.

[0035] The bottom side of the crushing tank 1 is sleeved in the corresponding screening box 9, and the material filtered through the first filter holes 2 is discharged and collected along the discharge pipe 901 of the screening box 9, and the material not filtered through the first filter holes 2 is discharged and collected along the discharge pipe 102.

[0036] The bottom side of the screening box 9 is arranged in an inclined shape, and the discharge pipe 901 is connected to the lowest end of the bottom side of the screening box 9.

[0037] The screening box 9 is fixedly mounted on the corresponding frame 11 through the corresponding coil spring 10. The crushing tank 1 is fixedly mounted on the frame 11 through the corresponding fixing plate 12.

[0039] The hollow setting of the crushing press 7 can not only reduce the overall weight of the crushing press 7, but also, under the friction energy dissipation effect of the damping particles 13 for vibration reduction, can significantly reduce the vibration amount generated by the crushing press 7 when grinding and crushing the material, thereby improving the crushing effect of the material and effectively maintaining the overall structural stability of the utility model.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
