Description

Wear-resisting screen plate for coal separator Technical Field The utility model relates to the technical field of mechanical equipment, in particular to a wear-resistant screen plate for a coal separator. Background In the coal processing and beneficiation industries, a coal separator is used as one of key equipment, and the performance of a screen plate of a core component of the coal separator directly influences the coal separation efficiency and the service life of the equipment. The main function of the sieve plate is to classify coal according to granularity by sieving, and simultaneously bear multiple functions of impact, abrasion, corrosion and the like of materials. However, in the actual use process, the existing sieve plate has the problem of insufficient wear resistance, so that the service life of the sieve plate is short, frequent replacement is required, and the maintenance cost and the downtime are increased. In addition, the traditional sieve plate material has poor impact resistance, is easy to deform or damage when facing high-strength working environment, and further influences sieving effect and production efficiency. At present, although part of the screen plates adopt surface hardening treatment or composite materials to improve the wear resistance, the methods have complex process and high cost, and the balance of the wear resistance and the toughness is difficult to be achieved. Therefore, developing a screen plate with excellent wear resistance, strong impact resistance and economy and practicability becomes a technical problem to be solved in the technical field of the current coal separator. Disclosure of utility model The utility model aims to provide a wear-resistant screen plate for a coal separator, which solves the problems in the background art. The utility model discloses a wear-resistant screen plate for a coal separator, which mainly comprises a base plate, a wear-resistant layer arranged on the base plate and a fixing frame arranged on one side of the base plate, wherein the base plate is of a main structure, and the wear-resistant layer and the fixing frame are both arranged on the base plate. The wear-resistant layer is movably connected with the base plate through the embedded block, and the embedded block drives the wear-resistant layer to adjust the position of the wear-resistant layer on the base plate in the horizontal direction. The utility model further adopts the technical scheme that a threaded hole is formed in the embedded block, an adjusting bolt connected with the threaded hole is arranged on the outer side of the embedded block, and the embedded block is screwed into the threaded hole through the adjusting bolt and is matched with a guide rail on the base plate to enable the base plate to move horizontally. The base plate is provided with a guide rail matched with the embedded block, and the position of the wear-resistant layer can be transversely adjusted on the base plate by matching with the embedded block. The fixing frame comprises a side plate, a clamping block arranged at the bottom end of the side plate and a locking plate arranged at the top end of the side plate, wherein the locking plate is U-shaped and is hung against the sieve plate to form an upper fixing point, the bottom clamping block fixes the sieve plate through the self weight of the base plate to form a bottom supporting point, an installer does not need to fix the sieve plate through an additional tool, and the installation process is greatly simplified. The side plate is provided with a through hole, the position of the through hole corresponds to the mounting hole of the base plate, and the fixing bolt can penetrate through the through hole to be connected with the base plate. The locking plate is U-shaped, and the upper side of the locking plate is similar to the mechanical equipment clamp in structure, so that the locking plate is convenient to detach and install quickly. According to the further technical scheme, a groove is formed in one side, away from the side plate, of the clamping block, a metal coating is arranged on the surface of the groove, and the clamping block is more stably attached to the substrate due to the groove and the metal coating. The wear-resistant screen plate for the coal separator has the beneficial effects that the wear-resistant screen plate for the coal separator is simple in structure, low in cost and capable of being put into use in a large batch, the screen plate can be quickly fixed through the fixing frame, the screen plate is fixed through the clamping blocks due to the weight of the base plate, the position of the wear-resistant layer is adjusted through the adjusting bolts, the service life of the screen plate is greatly prolonged, the stability is improved, and the working efficiency of the coal separator is improved.
