[0001] The utility model relates to the technical field of crusher maintenance doors, in particular to a clinker crusher maintenance door. Background Art

[0002] Clinker is a semi-finished product obtained by calcining limestone, clay and other raw materials at high temperature. Clinker crusher is often used in the production of cement clinker. It mainly performs preliminary crushing of limestone, clay and other raw materials. It is characterized by a large crushing ratio and high output.

[0003] Since the scraper of the crusher is easy to fall off during the production process, personnel need to enter the crusher to remove it. Common maintenance door types include bolt connection, pressure plate type, traditional hinge type and other structures. Among them, although the traditional hinge type is easy to open and close, there is usually a gap between the two doors after closing, resulting in poor sealing. Therefore, a clinker crusher maintenance door is proposed to address the above problems. Utility Model Content

The sealing device 5 comprises a rubber layer 51, a straight plate 52, a first fixed plate 53, a wear-resistant layer 54 and a second fixed plate 55. A second fixed plate 55 with a concave side is tightly fitted on the front side of the maintenance door body 3, and the first fixed plate 53 is fixedly connected to the left and right sides of the second fixed plate 55. The straight plate 52 is tightly fitted on the rear side of the second fixed plate 55, and the outer side of the straight plate 52 is wrapped with a rubber layer 51. By providing the sealing device 5 between the two maintenance door bodies 3, the sealing effect at the crusher body 1 is increased, and by providing a movable structure for the sealing device 5, it does not affect the opening and closing of the maintenance door body 3.

[0024] The rear side of the first fixing plate 53 is fixedly connected with a wear-resistant layer 54, which fits tightly against the inspection door body 3, and the rubber layer 51 fits tightly against the gap between the two inspection door bodies 3, so that the first fixing plate 53 and the inspection door body 3 are not easily worn when they fit together; a hand-tightening bolt 6 is spirally connected to one of the first fixing plates 53, and one end of the hand-tightening bolt 6 is inserted into one of the inspection door bodies 3 to facilitate fixing the inspection door body 3 after closing; a support for supporting is fixedly connected to the rear side of one of the inspection door bodies 3 Block 8, an electric telescopic rod 7 fits tightly inside the support block 8, one end of the electric telescopic rod 7 passes through the inspection door body 3 and is fixedly connected to one of the first fixed plates 53, so as to facilitate the movement of the straight plate 52 and the rubber layer 51; a protective layer 9 is fixedly connected to the rear side of the inspection door body 3, a sliding bar 10 with a T-shaped cross-section is fixedly connected to one side of the straight plate 52, a handle 11 is fixedly connected to the top of the sliding bar 10, and the sliding bar 10 and the recess of the second fixed plate 55 fit tightly, so as to facilitate the replacement of the straight plate 52 and the rubber layer 51.

[0025] Working process: When the maintenance door of the clinker crusher is in use, the crusher body 1 is first placed in a suitable position. During use, if the scraper falls off, the user needs to enter from the maintenance door body 3. Since the height difference between the maintenance port and the inside of the crusher body 1 is large, about 1m, it is inconvenient to enter and exit. The maintenance door body 3 and the platform are lowered by 600mm on the original basis, and the steel plate is welded at the lowered position above, and the castable is poured. Then the maintenance door body 3 needs to be opened, and the user turns the hand-tightening bolt 6 in the loose direction until it is taken out, and then starts the electric telescopic rod 7 to put it in a stretched state. Since the electric telescopic rod 7 is fixedly connected to one of the first fixed plates 53, the first fixed plate 53 and the second fixed plate 55 are fixedly connected, and the second fixed plate 55 is connected to the straight plate 52 through the sliding bar 10, that is, the electric telescopic rod 7 is connected to the straight plate 52. The movable straight plate 52 and the rubber layer 51 move in the same direction until the rubber layer 51 is completely away from the gap between the two inspection door bodies 3. At this time, the inspection door body 3 can be pushed open. Under the action of the hinge 4, the inspection door body 3 is in an open state, which is convenient for the user to enter the interior of the crusher body 1. When the elasticity of the rubber layer 51 decreases after long-term use and needs to be replaced, the user holds the handle 11 to move the straight plate 52 upward, driving the sliding bar 10 to move upward in the recess of the second fixed plate 55 until the straight plate 52 and the rubber layer 51 are completely removed, and then the sliding bar 10 at the new straight plate 52 is inserted into the recess of the second fixed plate 55. By providing the sealing device 5 between the two inspection door bodies 3, the sealing effect at the crusher body 1 is increased, and by providing the movable structure of the sealing device 5, it does not affect the opening and closing of the inspection door body 3.
