Embodiment Construction

[0010] The present invention will now be further described in conjunction with specific examples, and the following examples are intended to illustrate the present invention rather than further limit the present invention.

[0011] Such as figure 1 A combined self-fixing boltless liner is shown, including a liner 1, a fixed rivet 2 and a combined rivet 3. The four fixed rivets 2 are arranged at 90° intervals to divide the cylinder into four areas along the circumference. Several lining plates 1 are arranged between two adjacent fixed riveting plates 2 , and composite riveting plates 3 are inserted between the lining plates 1 .

[0012] The combined riveting plate 3 is spliced ​​by ordinary carbon steel plates, and its width can be adjusted accordingly according to the actual gap left after the liner plate 1 is assembled.

[0013] In order to apply the prestressing force, an external force is required to drive the combined riveting plate 3 into the wedge-shaped gap, expand the...

Abstract

The invention relates to a combined self-fixed bolt-free liner plate, including liner plates, fixed riveting plates and combined riveting plates. Four pieces of fixed riveting plates are arranged in interval of 90 degrees to divide the cylinder along the circumferential into four regions; a plurality of liner plates are arranged between two adjacent fixed riveting plates; and combined riveting plates insert among the liner plates. The invention has the beneficial effects of good safety and reliability, elimination of labor-consuming and environmentally unfriendly common problems such as powder leakage and bolt tightening, and improved operating rate of the equipment.

Description

technical field [0001] The invention relates to a combined self-fixing bolt-free liner. Background technique [0002] With the modernization of the cement production line and the enlargement of the production scale, the operation rate of various equipment on the production line is required to be higher and higher, and one of the keys to ensure a high operation rate is to improve the reliability and service life of the main components on the equipment . Each liner of the traditional cement mill cylinder is fixed on the cylinder with bolts. When the cylinder and the liner are deformed during high temperature operation, broken bolts and powder leakage are common phenomena, and the usual maintenance and repair work is very heavy. . Contents of the invention [0003] The technical problem to be solved by the present invention is: based on the above problems, the present invention provides a combined self-fixing bolt-free liner. [0004] A technical solution adopted by the pr...
