Description

Technical Field

[0001] The utility model belongs to the technical field of ball mill equipment components, and more specifically relates to a grading lining plate for a mill for processing solid and hazardous waste. Background Art

[0002] The ball mill is a key equipment for crushing materials after they are broken. Among them, the liner installed on the inner wall of the ball mill drum is a key component of the ball mill. In the prior art, in order to achieve automatic classification of materials in the ball mill, a classification liner is usually used. At present, common classification liners are simply bolted to the inner wall of the ball mill drum by bolts. When the ball mill runs for a long time, the classification liner vibrates due to the continuous impact of the material and the grinding body, causing the bolts connecting the classification liner and the drum to gradually loosen, resulting in a change in the position of the classification liner, which not only reduces the ability of the classification liner to lift the material and the grinding body, but also causes the wear of the classification liner to increase, greatly reducing the life of the classification liner.

[0027] See also Figures 1 to 3 , now a classification lining plate for a solid waste mill provided by the utility model is described. The classification lining plate for a solid waste mill includes a lining plate body 1, the upper end surface of the lining plate body 1 is a working surface, the working surface is inclined, and a lifting convex rib 101 is provided in the middle of the working surface along its inclined direction, and a mounting hole 11 is provided in the middle of the lifting convex rib 101, the mounting hole 11 passes through the lining plate body 1 longitudinally, and the mounting hole 11 includes a first hole body 111 and a second hole body 112 connected up and down. In use, the rod of the hexagonal bolt 3 passes through the second hole body 112 and is connected to the inner wall of the ball mill drum, and the head of the hexagonal bolt 3 abuts against the bottom of the second hole body 112. A locking component is provided in the second hole body 112, and the locking component locks the head of the hexagonal bolt 3 to limit the rotation of the hexagonal bolt 3.

[0028] In this embodiment, the length of the lifting rib 101 is equivalent to the width of the liner body 1, and the cross-section of the lifting rib 101 is arched. In practical applications, the lifting rib 101 increases the friction between the liner body 1 and the grinding body and the material. Under the action of the lifting rib 101, the liner body 1 can more easily lift the grinding body and the material to a predetermined height.

[0029] The utility model provides a grading liner for a solid and hazardous waste processing mill. Compared with the prior art, during the installation of the liner body 1, the liner body 1 is connected to the inner wall of the ball mill drum by using a hexagonal bolt 3 through a mounting hole 11, and then a locking component arranged in the mounting hole 11 is used to lock the head of the hexagonal bolt 3, so that the hexagonal bolt 3 cannot rotate, thereby preventing the hexagonal bolt 3 from loosening when the liner body 1 is subjected to the impact vibration of the grinding body and the material.

[0030] In some embodiments, see Figures 3 to 7 , an annular groove 114 is provided on the side wall of the lower end of the first hole body 111 in the circumferential direction. In the present embodiment, the annular groove 114 is connected to the bottom surface of the first hole body 111. A longitudinal slide groove 113 is also provided on the side wall of the first hole body 111. In the present embodiment, the number of the longitudinal slide grooves 113 is two, and the two longitudinal slide grooves 113 are symmetrically arranged. The upper end of the longitudinal slide groove 113 penetrates the first hole body 111 upward, and the lower end of the longitudinal slide groove 113 is connected to the annular groove 114. The locking component includes a locking block 2, which is slidably arranged in the first hole body 111 and is connected to the first A hole body 111 is rotatably connected, and a stopper 21 for slidingly cooperating with the longitudinal slide groove 113 is provided on the side wall at the lower end of the locking block 2. It is easy to understand that the number of the stopper 21 is two, and the two stoppers 21 correspond to the two longitudinal slide grooves 113 respectively. In this embodiment, the height of the stopper 21 is smaller than the width of the annular groove 114. A connecting portion 24 for cooperating with a wrench is provided at the upper end of the locking block 2. In this embodiment, the connecting portion 24 is a hexagonal boss, and a hexagonal groove 20 for cooperating with the head of the hexagonal bolt 3 is provided at the lower end of the locking block 2. 1. The bottom of the hexagonal groove 201 is connected with a first spring 22. In actual application, first remove the locking block 2 from the liner body 1, then insert the hexagonal bolt 3 into the second hole 112, use a wrench to rotate the hexagonal bolt 3 for pre-tightening, and when the pre-tightening of the hexagonal bolt 3 is completed, insert the locking block 2 into the first hole 111, so that the stopper 21 is inserted into the longitudinal slide groove 113, so that the hexagonal groove 201 on the locking block 2 is sleeved on the head of the hexagonal bolt 3, and then use a wrench to press down the connecting portion 24 on the locking block 2 to slide the locking block 2 downward The first spring 22 is compressed, and the stopper 21 slides downward into the annular groove 114. The locking block 2 is then rotated by a wrench to make the stopper 21 slide in the annular groove 114, and the hexagonal bolt 3 is tightened with the help of the hexagonal groove 201. After the hexagonal bolt 3 is tightened, the wrench on the connecting portion 24 is released. Under the action of the elastic force of the first spring 22, the locking block 2 has an upward movement tendency, so that the stopper 21 is pressed against the upper side wall of the annular groove 114. The friction between the stopper 21 and the annular groove 114 can limit the rotation of the locking block 2 and the hexagonal bolt 3.

[0031] Optional, see Figure 6 to Figure 7A contact piece 23 is slidably provided in the hexagonal groove 201, and the first spring 22 is connected between the contact piece 23 and the bottom surface of the hexagonal groove 201. In application, the contact piece 23 contacts the head of the hexagonal bolt 3, thereby avoiding direct contact between the first spring 22 and the head of the hexagonal bolt 3.

[0032] Optionally, in order to increase the friction between the stopper 21 and the annular groove 114 , anti-slip grooves may be provided on the upper end surface of the stopper 21 , ie, the contact surface between the stopper 21 and the annular groove 114 .

[0033] In some embodiments, see Figures 4 to 5 A plurality of slots 115 are provided on the upper side wall of the annular groove 114 at intervals. The slots 115 are connected to the first hole body 111. The width of the slots 115 is greater than the width of the stopper 21. When in use, the locking block 2 is rotated to tighten the hexagonal bolt 3 so that the stopper 21 slides below the slot 115. After the locking block 2 is loosened by the wrench, the stopper 21 can move upward under the action of the first spring 22 and abut against the slot 115. The mutual cooperation between the stopper 21 and the slot 115 can limit the rotation of the locking block 2, thereby preventing the hexagonal bolt 3 from loosening.

[0034] In some embodiments, see Figure 3 to Figure 4 A weight-reducing groove 12 is provided on the lower end surface of the liner body 1, which is used to reduce the weight of the liner body 1 and save production materials. A mounting groove 13 is also connected to the upper end circumference of the weight-reducing groove 12, and a rubber pad 4 is provided in the mounting groove 13. In the present embodiment, the rubber pad 4 is an annular ring pad adapted to the mounting groove 13. In application, the thickness of the rubber pad 4 is slightly larger than the depth of the mounting groove 13. The rubber pad 4 is clamped between the liner body 1 and the inner wall of the ball mill drum, which can buffer the impact force on the liner body 1, thereby reducing the vibration of the liner body 1.
