Description

Screen material filter screen structure of pulverizer Technical Field The utility model relates to the technical field of screening filter screens of crushers, in particular to a screening filter screen structure of a crusher. Background The pulverizer is a professional machine for crushing and processing large-size solid materials to a required size, in order to separate the particles of fragments with different sizes, the fragments are usually screened by a screen, the existing screen comprises a straight cylindrical container, the screen is fixed on the inner wall of the container, the fragments are poured from the upper end of the cylindrical container, the fragments fall down along the cylindrical container after screening, and coarse fragments remain on a screening screen. In the actual production process, the annular outer frame of the screen material filter screen and the screen body are usually integrated, and the conventional replacement mode is to replace the whole screen material filter screen, so that the screen body of the screen material filter screen is replaced regularly, a large amount of annular outer frame is wasted, and resource waste is caused. Disclosure of utility model The utility model aims to overcome the technical defects, and provides a screen material filter screen structure of a pulverizer, which solves the technical problems that in the prior art, an annular outer frame and a screen body of a screen material filter screen are usually arranged as a whole, and a conventional replacement mode is to replace the whole screen material filter screen, so that the screen body of the screen material filter screen is periodically replaced, a large amount of screen material filter screen outer frames are inevitably wasted, and resource waste is caused. In order to achieve the technical purpose, the technical scheme of the utility model provides a screening filter screen structure of a pulverizer, which comprises an annular outer frame, wherein an annular step groove is formed in the bottom of the annular outer frame, a net body is arranged in the annular step groove, a circular fixing frame for fixing the net body in the annular step groove or loosening the net body from the annular step groove is further arranged in the annular step groove, a clamping block is arranged on the side wall of the circular fixing frame, and an L-shaped clamping groove matched with the clamping block is formed in the bottom of the mounting ring. Further, the screen material filter screen structure also comprises a round supporting frame arranged between the screen body and the round fixing frame. Further, the fixed rod is installed at the top edge of the round supporting frame, and a fixed groove matched with the fixed rod is formed in the top of the annular step groove. Further, the upper end of the fixing rod is of a conical structure. Further, the circular support frame comprises a first inner ring and a first outer ring which are concentrically arranged, and the first inner ring is connected with the first outer ring through a first connecting rod. Further, the bottom of the clamping block is provided with a bulge, and the inner wall of the L-shaped clamping groove is provided with a groove matched with the bulge. Further, the protrusions are hemispherical structures. Further, the circular fixing frame comprises a second inner ring and a second outer ring which are concentrically arranged, and the second inner ring is connected with the second outer ring through a second connecting rod. The beneficial effects of the utility model include: 1. the circular fixing frame can be fixed in the annular step groove or loosened from the annular step groove through the matching of the L-shaped clamping groove and the clamping block, so that the net body can be fixed in the annular step groove or loosened from the annular step groove, and the net body can be disassembled and assembled, therefore, when the screen material filter screen is replaced, the net body is only required to be replaced, the whole screen material filter screen is not required to be replaced, and the waste of resources is avoided; 2. Through setting up circular support frame between the dictyosome and circular mount, at circular support frame top edge installation dead lever simultaneously, set up at annular step groove top with dead lever matched with fixed slot, when pressing circular support frame on the dictyosome, the dead lever passes the dictyosome and fixes inside the fixed slot, can avoid the screen cloth filter screen to break away from annular step groove when using.
