Abstract
Description
Technical Field
[0001] This utility model relates to the field of ball mill technology, specifically to an auxiliary feeding device for a ball mill. Background Technology
[0002] A ball mill is a commonly used grinding or crushing equipment. It consists of a horizontally rotating, slowly moving cylinder filled with spherical grinding media (steel balls, zirconia balls, alumina balls, pebbles, or ceramic balls). The working principle is that as the cylinder rotates, the spherical grinding media are lifted by friction against the inner wall of the cylinder. When the angle of ascent exceeds the angle of repose, the grinding media fall downwards. The material is pulverized by the impact of the falling grinding media and the grinding action between the media and the inner wall of the cylinder. When the material is discharged from the ball mill through the discharge pipe at one end, it tends to accumulate in the discharge pipe, potentially causing blockage and affecting the feeding process. Utility Model Content
[0003] In view of the problems in the prior art, this utility model provides an auxiliary feeding device for a ball mill.
[0004] The technical solution adopted by this utility model to solve its technical problem is an auxiliary feeding device for a ball mill, including a housing. A feeding pipe is fixed to one side of the housing, and a motor is fixed to the other side of the housing. The output shaft of the motor is connected to a crossbar via a coupling. An auger blade is fixed on the crossbar. A bearing seat is fixed inside the housing, and a support rod is fixed inside the bearing seat. Pulleys are fixed to both the support rod and the crossbar, and the two pulleys are connected by a belt. Multiple retaining sleeves are fixed to the support rod, and springs are fixed to each of the multiple retaining sleeves. A striking block is fixed to the end of the spring away from the sleeve. A discharge hopper is fixed to both sides of the box. An inclined outer frame is provided below the crossbar. A screen is fixed inside the outer frame. The two symmetrically arranged vertical inner walls of the box are provided with sliding grooves that fit the outer frame. The end of the outer frame away from the discharge pipe extends out of the box. A guide plate is provided below the outer frame and is connected to the box. A support is provided below the box. Brake rollers are installed at the four corners of the bottom end of the support. A hydraulic cylinder is fixed to the top of the support. The top of the piston rod of the hydraulic cylinder is connected to the box.
[0005] By adopting the above technical solution, the support is moved to the side of the ball mill's discharge pipe using a brake roller. The piston rod of the hydraulic cylinder drives the housing to move vertically. The height of the housing and the discharge pipe can be adjusted according to the height of the ball mill's discharge pipe. Moving the support allows the auger blades to be inserted into the ball mill's discharge pipe. After the end of the discharge pipe away from the housing is in contact with the ball mill's discharge pipe, the brake roller is locked. The motor's output shaft drives the crossbar to rotate. With the cooperation of the belt and pulley, the support rod rotates. The rotating auger blades facilitate the discharge of material from the discharge pipe. When the support rod rotates, multiple clamps rotate, and the striking blocks can strike the discharge pipe and the discharge pipe, thereby preventing blockage. After the material is fed into the housing, it falls down, and the inclined screen can screen the material.
[0006] Specifically, vertical rods are fixed at the four corners of the bottom of the box, and sleeves are fitted at the bottom of the four vertical rods, with the bottom of the four sleeves connected to the supports.
[0007] By adopting the above technical solution, the stability of the box can be improved by setting up the vertical rod and sleeve.
[0008] Specifically, a handle is fixed on the side of the outer frame away from the feed tube, two insert rods are provided above the handle, two through holes adapted to the insert rods are provided on the box body, and two slots adapted to the insert rods are provided on the handle.
[0009] By adopting the above technical solution, the slots on the insert rods and handles can prevent the outer frame from shifting. By lifting the two insert rods and pulling out the outer frame, the outer frame along with the screen can be removed for cleaning or replacement.
[0010] Specifically, the bottom ends of both discharge hoppers are fitted with sleeves, both sides of both discharge hoppers are provided with adjusting bolts, both sides of both sleeves are provided with screw holes adapted to the adjusting bolts, and both sides of both discharge hoppers are provided with multiple slots adapted to the adjusting bolts.
[0011] By adopting the above technical solution, after loosening the adjusting bolt and moving the sleeve vertically, the end of the adjusting bolt is screwed into the slots on both sides of the discharge hopper, which can adjust the height of the sleeve, making it easier to discharge the screened material into the collection container and reducing dust generation.
[0012] Specifically, an observation port is provided on one side of the box, and a glass panel is provided inside the observation port.
[0013] By adopting the above technical solution, the inside of the enclosure can be easily observed through the observation port and glass.
[0014] The beneficial effects of this utility model are:
[0015] (1) The auxiliary feeding device for a ball mill described in this utility model uses a brake roller to move the support to the side of the ball mill's discharge pipe. The piston rod of the hydraulic cylinder drives the housing to move vertically. The height of the housing and the discharge pipe can be adjusted according to the height of the ball mill's discharge pipe. Moving the support causes the auger blades to be inserted into the ball mill's discharge pipe. After the end of the discharge pipe away from the housing is in contact with the ball mill's discharge pipe, the brake roller is locked. The output shaft of the motor drives the crossbar to rotate. With the cooperation of the belt and pulley, the support rotates. The rotating auger blades facilitate the discharge of material in the discharge pipe. When the support rotates, multiple clamps rotate. The striking block can strike the discharge pipe and the discharge pipe, thereby preventing the discharge pipe and the discharge pipe from being blocked. After the material is fed into the housing, it falls. The inclined screen can screen the material.
[0016] (2) The auxiliary feeding device for a ball mill described in this utility model can adjust the height of the sleeve by loosening the adjusting bolt, moving the sleeve vertically, and screwing the end of the adjusting bolt into the slots on both sides of the discharge hopper. This facilitates the discharge of the screened material into the collection container and reduces the generation of dust. Attached Figure Description

Detailed Implementation
[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] To prevent blockage of the discharge pipe of the ball mill, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the auxiliary feeding device for a ball mill according to this utility model includes a housing 1. A feeding pipe 5 is welded and fixed to one side of the housing 1, and a motor 2 is bolted to the other side of the housing 1. The output shaft of the motor 2 is connected to a crossbar 7 via a coupling. An auger blade 6 is welded and fixed to the crossbar 7. A bearing seat 40 is bolted to the inside of the housing 1, and a support rod 4 is fixed inside the bearing seat 40. Pulleys 70 are fixed to both the support rod 4 and the crossbar 7. The two pulleys 70 are connected by a belt 71. Multiple retaining sleeves 41 are welded and fixed to the support rod 4, and springs 42 are welded and fixed to each retaining sleeve 41. The multiple springs 42 are located away from the retaining sleeves 4. A striking block 43 is welded and fixed to the end of the box 1. A discharge hopper 8 is welded and fixed to both sides of the box 1. An inclined outer frame 3 is provided below the crossbar 7. A screen 30 is welded and fixed inside the outer frame 3. The two symmetrically arranged vertical inner walls of the box 1 are provided with sliding grooves that are adapted to the outer frame 3. The end of the outer frame 3 away from the discharge pipe 5 extends to the outside of the box 1. A guide plate 31 is provided below the outer frame 3. The guide plate 31 is welded and connected to the box 1. A support 13 is provided below the box 1. Brake rollers are installed at the four corners of the bottom end of the support 13. A hydraulic cylinder 12 is fixed to the top of the support 13 by bolts. The top of the piston rod of the hydraulic cylinder 12 is connected to the box 1 by bolts.
[0026] In use, the support 13 is moved to the side of the discharge pipe of the ball mill (existing technology, not shown) using the brake roller. The piston rod of the hydraulic cylinder 12 drives the housing 1 to move vertically. The height of the housing 1 and the discharge pipe 5 can be adjusted according to the height of the discharge pipe of the ball mill. Moving the support 13 causes the auger blade 6 to be inserted into the discharge pipe of the ball mill. After the end of the discharge pipe 5 away from the housing 1 is in contact with the discharge pipe of the ball mill, the brake roller is locked. The output shaft of the motor 2 drives the crossbar 7 to rotate. With the cooperation of the belt 71 and the pulley 70, the support rod 4 rotates. The rotating auger blade 6 facilitates the discharge of material in the discharge pipe. When the support rod 4 rotates, multiple clamps 41 rotate with it. The striking block 43 can strike the discharge pipe and the discharge pipe 5, thereby preventing the discharge pipe and the discharge pipe 5 from being blocked. After the material is fed into the housing 1, it falls. The inclined screen 30 can screen the material.
[0027] To improve the stability of housing 1, for example, such as Figure 1As shown, vertical rods 14 are welded and fixed at the four corners of the bottom of the box 1, and sleeves 11 are fitted onto the bottom ends of the four vertical rods 14. The bottom ends of the four sleeves 11 are welded to the support 13.
[0028] To facilitate fixing or removing the outer frame 3, for example, as shown... Figure 3 As shown, a handle 32 is welded and fixed on the side of the outer frame 3 away from the feed tube 5. Two insert rods 33 are provided above the handle 32. Two through holes adapted to the insert rods 33 are provided on the box body 1. Two slots adapted to the insert rods 33 are provided on the handle 32.
[0029] When in use, the slots on the insert rods 33 and handles 32 prevent the outer frame 3 from shifting. By lifting the two insert rods 33 and pulling out the outer frame 3, the outer frame 3 and the screen 30 can be removed together for cleaning or replacement.
[0030] To facilitate the transfer of the sieved material into a container for material collection, for example, such as... Figure 1 As shown, the bottom ends of the two discharge hoppers 8 are fitted with sleeves 10, and the two discharge hoppers 8 are provided with adjusting bolts 9 on both sides. The two sleeves 10 are provided with screw holes that are compatible with the adjusting bolts 9 on both sides. The two discharge hoppers 8 are provided with multiple slots that are compatible with the adjusting bolts 9 on both sides.
[0031] When in use, loosen the adjusting bolt 9, move the sleeve 10 vertically, and then screw the end of the adjusting bolt 9 into the slots on both sides of the discharge hopper 8. This can adjust the height of the sleeve 10, which is conducive to discharging the screened material into the collection container and reducing dust generation.
[0032] To facilitate observation of the interior of housing 1, for example, as shown below. Figure 1 As shown, an observation port is provided on one side of the box 1, and a glass 101 is provided inside the observation port. The glass 101 is connected to the box 1 by adhesive.
[0033] In use, the support 13 is moved to the side of the discharge pipe of the ball mill (existing technology, not shown) by the brake roller. The piston rod of the hydraulic cylinder 12 drives the housing 1 to move vertically. The height of the housing 1 and the discharge pipe 5 can be adjusted according to the height of the discharge pipe of the ball mill. Moving the support 13 causes the auger blade 6 to be inserted into the discharge pipe of the ball mill. After the end of the discharge pipe 5 away from the housing 1 is in contact with the discharge pipe of the ball mill, the brake roller is locked. The output shaft of the motor 2 drives the crossbar 7 to rotate. With the cooperation of the belt 71 and the pulley 70, the support rod 4 rotates. The rotating auger blade 6 facilitates the discharge of material in the discharge pipe. When the support rod 4 rotates, multiple clamps 41 rotate with it. The striking block 43 can strike the discharge pipe and the discharge pipe 5, thereby preventing the discharge pipe and the discharge pipe 5 from being blocked. After the material is fed into the housing 1, it falls. The inclined screen 30 can screen the material.
[0034] Loosen the adjusting bolt 9, move the sleeve 10 vertically, and screw the end of the adjusting bolt 9 into the slots on both sides of the discharge hopper 8. This will adjust the height of the sleeve 10, making it easier to discharge the screened material into the collection container and reducing dust generation.
[0035] The slots on the insert rods 33 and handles 32 prevent the outer frame 3 from shifting. By lifting the two insert rods 33 and pulling out the outer frame 3, the outer frame 3 along with the screen 30 can be removed for cleaning or replacement.
