Description

Technical Field

[0001] The utility model relates to a coal slime crusher, in particular to an anti-sticking and wear-resistant casing structure of the coal slime crusher. Background Art

[0002] The casing of the traditional coal slime crusher is composed of side plates and end plates, without lining plates. The crushed material is the filter cake after the coal slime filter press is pressed. After drying, the moisture content is about 15%-20%. The coal slime has the characteristics of high moisture, low calorific value, fine particle size and high viscosity. After long-term use of the traditional casing, part of the coal slime will adhere to the inside, and the adhered coal slime is difficult to clean. The longer the use time, the more coal slime will be deposited and adhered inside, causing the effective crushing space inside the casing to continue to decrease, resulting in the continuous decrease in the working efficiency of the coal slime crusher and failing to reach the required processing capacity. After long-term use, the side plates and end plates will be worn out with holes. In severe cases, it will directly affect on-site production and cause equipment shutdown. At this time, the worn side plates or end plates can only be replaced as a whole, and the production of side plates or end plates takes a long time, is time-consuming and labor-intensive, and increases operation and maintenance costs. Utility Model Content

[0003] The main purpose of the utility model is to provide a non-sticking and wear-resistant coal slime crusher casing, in which polyethylene lining plates are installed inside the end plates and side plates, so as to achieve non-sticking materials and increase the wear life of the casing.

[0004] In order to achieve the above-mentioned purpose, the utility model provides an anti-sticking and wear-resistant coal slime crusher casing structure, including two end plates and two side plates, which together form an open frame that is transparent from top to bottom, wherein the top of the end plate is fixedly connected to the feed chute, the bottom of the end plate is fixedly connected to the crusher frame, and the inner sides of the end plate and the side plate are provided with removable polyethylene liners.

[0005] Preferably, the polyethylene liner is connected to the end plate and the side plate respectively by countersunk tenon bolts.

[0006] Preferably, a convex surface is provided on the polyethylene liner, and concave surfaces are provided at corresponding positions of the end plate and the side plate, and the convex surface can be inserted into the concave surface.

[0007] Further preferably, a threaded hole is provided on the concave surface, and one end of the bolt can push the boss surface of the polyethylene liner out of the concave surface after passing through the threaded hole.

[0008] More preferably, the end plates and the side plates are respectively provided with supporting plates, which surround the outer side of the polyethylene liner and are used to support the polyethylene liner.

[0009] Preferably, the crushing shaft of the crusher is fixedly provided with a dust shielding ring, and the dust shielding ring is located inside the end plate.

[0010] Further preferably, a sealing packing and a sealing pressure plate are provided at the connection between the end plate and the crushing shaft of the crusher, and the sealing packing seals the connection between the end plate and the frame through the sealing pressure plate.

[0011] The beneficial effects of the utility model are:

[0012] When crushing the coal slime filter cake, the polyethylene plate can effectively reduce the adhesion of coal slime materials, while improving the overall wear resistance of the casing and extending the service life of the casing. The double sealing structure at the end plate shaft can effectively prevent the coal slime dust in the crushing chamber from overflowing and causing environmental pollution outside the equipment. At the same time, the multiple fastening structures of the polyethylene liner can effectively prevent it from falling off, avoiding it from being transferred into the crushing chamber to break the crushing cutter head, etc., affecting the use of the equipment. The liner is easy and quick to replace, and the replacement time is short, the labor cost is low, and the operation and maintenance cost of the equipment is greatly reduced.

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0023] like Figure 1 As shown, the utility model provides an anti-sticking and wear-resistant coal slime crusher casing structure, wherein a feed chute 3 is installed above the crusher, and the coal slime enters the crusher through the feed chute 3 for crushing. The crusher includes a frame 4, a crushing roller and a cover shell arranged on the crushing roller and fixedly installed with the frame 4, the crushing roller is installed on the frame 4, the flange at the upper end of the cover shell is fixedly connected to the feed chute 3 by a bolt group, and the flange at the lower end of the cover shell is fixedly connected to the frame 4 by a bolt group.

[0024] Specifically, the cover shell includes two end plates 1 and two side plates 2, which together form an open frame that is transparent from top to bottom, wherein the top of the end plate 1 is fixedly connected to the feed chute 3, and the bottom of the end plate 1 is fixedly connected to the frame 4 of the crusher, and a detachable polyethylene liner 5 is provided on the inner side of the end plate 1 and the side plate 2, so that the coal slime material will adhere to the polyethylene liner 5, and the purpose of avoiding replacing the end plate 1 and the side plate 2 can be achieved by replacing the polyethylene liner 5.

[0025] Specifically, in this embodiment, if Figure 2 and Figure 3 As shown, the polyethylene liner 5 is connected to the end plate 1 and the side plate 2 respectively by countersunk tenon bolts 9. The head of the countersunk tenon bolt 9 has a tenon. The tenon and the hole are matched to avoid the problems of poor locking effect caused by the traditional bolts due to the large hole diameter and misalignment. In addition, Figure 2 and Figure 3 As shown, the polyethylene liner 5 is provided with a convex surface, and the end plate 1 and the side plate 2 are respectively provided with concave surfaces at corresponding positions. The convex surface can be inserted into the concave surface.
