Description

Technical Field

[0001] This application relates to the technical field of activated carbon production equipment, and in particular to an integrated machine for crushing and screening raw materials for activated carbon production. Background Technology

[0002] In activated carbon production, raw materials need to be crushed and screened to obtain materials of different particle sizes. Traditional equipment usually uses a single-stage crushing mechanism, which results in a large workload and severe wear. In addition, the crushing and screening processes are separated, and the dispersed equipment leads to material transfer and accumulation, low efficiency, and vibrating screens are prone to clogging and have low screening efficiency. Utility Model Content

[0003] This application provides an integrated crushing and screening machine for activated carbon production raw materials. The equipment is equipped with a two-stage crushing mechanism. First, the crushing rollers in the first-stage crushing chamber coarsely crush the activated carbon raw materials, and then the hammers in the second-stage crushing chamber finely crush the materials. The two-stage crushing mechanism reduces the load on the equipment, thereby reducing wear. The crushing chamber of the equipment is connected to a screen barrel. The crushed materials are conveyed to the screen barrel for direct grading and screening, avoiding material accumulation and improving the overall processing efficiency. The three rotating screens use centrifugal force to grade and screen the materials, improving screening efficiency.

[0004] This application provides an integrated crushing and screening machine for activated carbon production raw materials, including: a crushing chamber and a screen barrel. The crushing chamber includes a primary crushing chamber and a secondary crushing chamber. The top of the primary crushing chamber is provided with a feed inlet. Two crushing rollers with crushing teeth on their surfaces are movably installed inside the primary crushing chamber. One end of the two crushing rollers passes through the side wall of the primary crushing chamber and is equipped with a gear set. One of the crushing rollers is connected to a servo motor. The bottom of the primary crushing chamber is connected to the secondary crushing chamber. The secondary crushing chamber includes a box body and an internal column. A roller shaft is movably installed on the opposite inner wall of the secondary crushing chamber. One end of the roller shaft passes through the side wall of the secondary crushing chamber and is connected to a servo motor. Several discs are welded at equal intervals on the roller shaft. Two connecting rods are welded through the discs. A hammer head is movably installed on the connecting rod between every two discs. Two support rods are welded to the opposite outer walls of the secondary crushing chamber. The bottom of the secondary crushing chamber is equipped with a discharge port, which is connected to an auger conveying pipe. The end of the auger conveying pipe is connected to a screen barrel. A rotating shaft is installed at the top of the screen barrel. One end of the rotating shaft passes through the top of the screen barrel and is connected to a servo motor. Three screens with decreasing apertures are installed at equal intervals on the side wall of the rotating shaft. Three grooves are set at equal intervals on the inner wall of the screen barrel. The three screens are movably clamped in the corresponding grooves. Three guide grooves are welded to the outer wall of the screen barrel at the positions corresponding to the screens. A collection bag is connected to the end of each guide groove. A discharge port is provided at the bottom of the screen barrel.

[0005] Furthermore, the sidewall of the column is composed of several strips.

[0006] Furthermore, the auger conveyor pipe has an upper inclined section and a lower inclined section. The upper inclined section is equipped with a screw, and the side wall of the screw is equipped with helical blades. One end of the screw is connected to a servo motor.

[0007] Furthermore, the screen includes a first screen, a second screen, and a third screen, with the screen aperture decreasing sequentially. Furthermore, a discharge port is provided on the side wall of the screen barrel corresponding to the position of each guide chute.

[0008] Furthermore, each discharge port is equipped with a baffle plate.

[0009] As can be seen from the above technical solution, this application provides an integrated crushing and screening machine for activated carbon production raw materials, including: a crushing chamber and a screen barrel. The crushing chamber includes a primary crushing chamber and a secondary crushing chamber. A feed inlet is provided at the top of the primary crushing chamber, through which the activated carbon production raw materials to be crushed are fed into the primary crushing chamber. Two crushing rollers with crushing teeth on their surfaces are movably installed inside the primary crushing chamber. A gear set is installed at one end of each crushing roller through the side wall of the primary crushing chamber. One of the crushing rollers is connected to a servo motor, which is connected to a power source. When the servo motor is started, it rotates, driving the connected crushing roller to rotate. Through the action of the gear set, the two crushing rollers rotate towards each other, and the crushing teeth on the surface of the crushing rollers coarsely crush the activated carbon production raw materials. The bottom of the primary crushing chamber is connected to the secondary crushing chamber. The coarsely crushed material falls into the secondary crushing chamber, which includes a housing and an internal column. Both ends of the column are welded to the inner wall of the housing. A roller is movably installed on the opposite inner wall of the secondary crushing chamber. One end of the roller passes through the side wall of the secondary crushing chamber and is connected to a second servo motor, which is connected to a power source. Several discs are equidistantly welded onto the roller, and two connecting rods are welded through each disc. A hammer is movably installed on the connecting rod between every two discs. When the second servo motor is started, it rotates, causing the connected roller to rotate. This causes the hammers between adjacent discs to be thrown out by centrifugal force, striking the material entering the secondary crushing chamber and finely crushing it. This two-stage crushing mechanism reduces the weight of the material. To reduce equipment load and thus wear, two support rods are welded to the outer walls of the secondary crushing chamber on each side, providing support for the crushing chamber. A feed inlet is located at the bottom of the secondary crushing chamber, connected to an auger conveyor pipe. Material crushed in the secondary crushing chamber is screened by slats on the side wall of the cylinder. Qualified material falls into the auger conveyor pipe, while unqualified material continues to be crushed by rotating hammers. The end of the auger conveyor pipe connects to a screen barrel, where material is transported. A rotating shaft is located at the top of the screen barrel, with one end penetrating the top and connected to a servo motor. The servo motor is connected to a power source. Three screens with decreasing apertures are installed equidistantly on the side wall of the rotating shaft. Three grooves are equidistantly located on the inner wall of the screen barrel, with the three screens movable and clamped in their corresponding positions. Inside the tank, servo motor three is started, which drives the connected rotating shaft to rotate. This causes the three screens on the side wall of the rotating shaft to rotate with the shaft in the slots. The rotation of the three screens uses centrifugal force to classify and screen the material, thereby improving screening efficiency. Three guide troughs are welded to the outer wall of the screen barrel at the positions corresponding to the screens. Each guide trough is connected to a collection bag at its end. The bottom of the screen barrel is equipped with a discharge port with a cover. Under the action of centrifugal force, large particles of material remain on the first screen and then enter the collection bag at the end through the guide trough. Medium particles pass through the first screen and remain on the second screen, then enter the collection bag through the guide trough. Small particles remain on the third screen and then enter the collection bag through the guide trough. After screening is completed, the cover is opened, and the fine powder is discharged from the bottom discharge port.

[0010] In summary, the beneficial effects of this application are as follows: 1. The equipment is equipped with a two-stage crushing mechanism. First, the crushing roller in the first-stage crushing chamber coarsely crushes the activated carbon raw material, and then the hammer in the second-stage crushing chamber finely crushes the material. The two-stage crushing mechanism reduces the load on the equipment, thereby reducing the wear and tear on the equipment.

[0011] 2. The crushing chamber of this equipment is connected to a screen barrel. The crushed material is conveyed to the screen barrel for direct grading and screening, avoiding material accumulation and improving overall processing efficiency. The three screens rotate to use centrifugal force to grade and screen the material, thereby improving screening efficiency.

[0012] 3. The equipment is equipped with an auger conveyor pipe, which transports the crushed material to the screen bucket. The closed conveying system reduces dust spillage and avoids spillage and loss of material during the transfer process. Attached Figure Description

[0020] As can be seen from the above technical solutions, see [link / reference]. Figures 1-5 .

[0021] Example 1: An integrated crushing and screening machine for activated carbon production raw materials includes: a crushing chamber and a screen 3. The crushing chamber includes a primary crushing chamber 1 and a secondary crushing chamber 2. The top of the primary crushing chamber 1 is provided with a feed inlet 4, through which the activated carbon production raw materials to be crushed are fed into the primary crushing chamber 1. Two crushing rollers 5 with crushing teeth on their surfaces are movably installed in the primary crushing chamber 1. One end of the two crushing rollers 5 passes through the side wall of the primary crushing chamber 1 and is equipped with a gear set 6. One of the crushing rollers 5 is connected to a servo motor 7, which is connected to a power source. When the servo motor 7 is started, it rotates, driving the connected crushing roller 5 to rotate. Through the action of the gear set 6, the two crushing rollers 5 rotate towards each other, and the crushing teeth on the surface of the crushing rollers 5 coarsely crush the activated carbon production raw materials. The bottom of the primary crushing chamber 1 is connected to the secondary crushing chamber 2, and the coarsely crushed material falls into the secondary crushing chamber 2. The secondary crushing chamber 2 includes a housing and an internal column 8. The two ends of the column 8 are welded to the inner wall of the housing. A roller 9 is movably installed on the inner wall of the secondary crushing chamber 2. One end of the roller 9 passes through the side wall of the secondary crushing chamber 2 and is connected to a servo motor 2. The servo motor 2 is connected to a power source. Several discs 10 are welded at equal intervals on the roller 9. Two connecting rods 11 are welded through the discs 10. A hammer 12 is movably installed on the connecting rod 11 between every two discs 10. When the servo motor 2 is started, the servo motor 2 rotates and drives the connected roller 9 to rotate, so that the hammers 12 between adjacent discs 10 are thrown out and hit the material under the action of centrifugal force, which finely crushes the material entering the secondary crushing chamber 2. The two-stage crushing mechanism reduces the load on the equipment and thus reduces the wear of the equipment. Two support rods 14 are welded to the outer walls of the secondary crushing chamber 2. The four support rods 14 support the crushing chamber. The bottom of the secondary crushing chamber 2 is provided with a feed inlet 13, which is connected to an auger conveyor pipe 15.

Three grooves are provided at equal intervals on the inner wall of the screen barrel 3. The three screens 19 are movably locked in the corresponding grooves. When the servo motor 16 is started, the servo motor 16 drives the connected... The rotating shaft 17 rotates, causing the three screens 19 on the side wall of the rotating shaft 17 to rotate in the slots along with the rotating shaft 17. The rotation of the three screens 19 utilizes centrifugal force to classify and screen the material, thereby improving screening efficiency. Three guide troughs 20 are welded to the outer wall of the screen barrel 3 at the positions corresponding to the screens. Each guide trough 20 is connected to a collection bag at its end. The bottom of the screen barrel 3 is provided with a discharge port, which is equipped with a cover. Under the action of centrifugal force, large particles of the material remain on the first screen 19 and then enter the collection bag at the end through the guide trough 20. Medium particles pass through the first screen 19 and remain on the second screen 19, then enter the collection bag through the guide trough 20. Small particles remain on the third screen 19 and then enter the collection bag through the guide trough 20. After screening is completed, the cover is opened, and the fine powder is discharged from the bottom discharge port.

[0022] In a preferred embodiment, the side wall of the column cylinder 8 is composed of several strips. The strips on the side wall of the column cylinder 8 screen the material crushed by the hammer 12. The qualified material falls into the auger conveying pipe 15 through the discharge port 13, while the unqualified material is further crushed by the rotating hammer 12.
