Description

Technical Field

[0001] The utility model relates to the technical field of semi-autogenous grinding machine equipment, in particular to a semi-autogenous grinding dustpan lining plate. Background Art

[0002] Semi-autogenous grinding mill is a kind of ore crushing equipment, which combines the characteristics of traditional autogenous grinding mill and ball mill. Semi-autogenous grinding mill uses part of the crushed material in the cylinder as the grinding medium to grind the ore. The inner wall of the cylinder to which the dustpan liner is fixed is subjected to the impact and wear from the grinding medium, block materials and slurry. The outer side of the liner is generally provided with a lifting bar to lift the material to a high place and drop it. After long-term use, the lifting bar is seriously worn. It is cast as one piece with the liner, so the whole liner needs to be replaced. After the bolts of the existing liner are removed, the liner needs to be manually moved to tie the slings and lift the liner. This process is time-consuming. In order to solve the problem of time-consuming liner lifting, a new type of semi-autogenous grinding dustpan liner is needed. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model provides Figure 1-4 A semi-self-grinding dustpan liner shown includes a liner body 1, and a splicing component is arranged on the side of the liner body 1;

[0019] It should be noted that a lifting bar 2 is provided on the front of the liner plate body 1, and a mounting hole 201 is provided on the front of the lifting bar 2. The dustpan liner plate body 1 is generally fixed to the inner wall of the semi-autogenous mill cylinder body by bolts passing through the mounting hole 201. Inside the semi-autogenous mill, the lifting bar 2 on the dustpan liner plate body 1 is responsible for continuously lifting the grinding medium and materials. When these lifted materials reach a certain height, they will throw and fall to each other. This process is the key to realizing the self-grinding effect of the semi-autogenous mill.

[0020] During the operation of the semi-autogenous mill, the liner plate body 1 is subjected to impact and wear from the grinding media, block materials and slurry. These grinding media move in the cylinder body, impact and grind the ore, and also cause impact damage and grinding to the cylinder body and liner plate, resulting in shape changes, affecting the height of material lifting, and causing energy loss. Therefore, the liner plate body 1 needs to be replaced after wear;

[0021] Specifically, the splicing component includes a ridge 3 and a lap groove 301, the ridge 3 is arranged on one side of the liner plate body 1, and the lap groove 301 is arranged on the other side of the liner plate body 1, the ridge 3 and the lap groove 301 are mutually spliced ​​between the liner plate bodies 1, wherein there is a connection gap at the splicing, and the gap can ensure the free flow of grinding media and materials between the liner plate bodies 1, and avoid hindering the movement of materials due to the close fit between the liner plate bodies 1. Due to the high-speed impact during the grinding process, the semi-autogenous mill will generate a lot of heat during operation, causing thermal expansion of the cylinder. If there is no appropriate gap between the liners, the expansion of the cylinder may cause the pressure between the liner plate bodies 1 to increase, thereby affecting the stability of the connection between the liner plate bodies 1;

[0022] The top and bottom of the liner body 1 are both provided with positioning components for lining plate hoisting;

[0023] Specifically, the positioning assembly includes a positioning threaded hole 101, a threaded block 7 is disposed inside the positioning threaded hole 101, a compression spring 5 is disposed on the side of the threaded block 7, and a pressure plate 4 is disposed at one end of the compression spring 5 away from the threaded block 7;

[0024] It should be noted that the inner wall of the positioning threaded hole 101 is provided with threads for rotation and fixing of the threaded block 7, the pressing plate 4 is in close contact with the inside of the positioning threaded hole 101, the pressing plate 4 is away from the side of the compression spring 5 and is fixedly connected with a nylon pad 401 inside the positioning threaded hole 101, the nylon pad 401 and the pressing plate 4 are bonded with high temperature resistant glue, and its position is located at the connection between the positioning threaded hole 101 and the outside, which is used to prevent the material from squeezing and impacting the outside of the pressing plate 4, and it is in close contact with the inner wall of the positioning threaded hole 101, so as to prevent the external slurry from entering the inner cavity of the positioning threaded hole 101;

[0025] A limiting member 6 is provided in the middle of the compression spring 5;

[0026] Specifically, the stopper 6 includes a sleeve rod 601, one end of which is fixedly connected to the side of the pressure plate 4, and the other end of the sleeve rod 601 is inserted with an insertion rod 602, and one end of the insertion rod 602 away from the sleeve rod 601 is fixedly connected to the outer side of the threaded block 7.

[0027] It should be noted that the sleeve rod 601 and the pressure plate 4, the insertion rod 602 and the outer side of the threaded block 7 are all fixed by welding, and the other end of the insertion rod 602 is located in the inner cavity of the sleeve rod 601 and is fixedly connected with a slider 6021, the slider 6021 is in a round shape, and the diameter of the inner cavity end of the sleeve rod 601 is larger than the diameter of the slider 6021, so as to limit the position of the sleeve rod 601 and the insertion rod 602, thereby guiding the deformation of the compression spring 5 to prevent it from being skewed;

[0028] The inner wall of the positioning threaded hole 101 is provided with a lifting claw fixing hole 1011, and the lifting claw fixing hole 1011 is used to limit the position of the end of the lifting claw when the lifting claw is inserted into the positioning threaded hole 101, so as to prevent the lifting claw from sliding in the positioning threaded hole 101 and affecting the lifting of the lifting claw to the liner plate body 1;

[0029] In actual use, by providing positioning components at the top and bottom of the lining plate body 1, when the lifting bar 2 of the dustpan lining plate body 1 is severely worn, in order not to affect the lifting of the crushed materials by the lifting bar 2, the user uses a crane to squeeze the hook into the positioning threaded hole 101, and the pressure plate 4, under the guidance of the sleeve rod 601 and the insertion rod 602, squeezes the compression spring 5, thereby providing a hook fixing fulcrum for the lifting of the lining plate body 1, avoiding the time-consuming manual binding and lifting with slings, and saving the time for lifting the lining plate body 1.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
