Rapid manual screen replacing device

Abstract

The invention discloses a rapid manual screen replacing device. The rapid manual screen replacing device comprises a forming part and a rapid opening and closing part. The forming part comprises a transition base, a mold body, a distribution cone and a mouth die plate which are coaxially arranged in sequence. The ends, close to the mold body, of the transition base are provided with circumferential protruding ribs protruding outwards in the radial direction respectively. A transition plate is clamped between the end faces, close to the mold body, of the transition base. The rapid opening and closing part comprises a rapid Haff buckle. The rapid Haff buckle comprises two bodies which can be buckled together. Each body is in a semicircular arc shape, the two bodies are buckled to the outer circumferences of the two protruding ribs in the circumferential direction of the bodies, and the inner walls of the bodies are matched with the two protruding ribs, and one ends of the two bodies are hinged together. A rapid disassembly buckle is arranged between the other ends of the two bodies. According to the rapid manual screen replacing device, the transition plate is clamped and positioned through the rapid Haff buckle by means of the transition base and the mold body, in this way, rapid disassembly and assembly of a filter plate are achieved, and the filter plate can be cleaned to remove impurities or replaced; the structure is novel and reliable; operation is easy and convenient; the workload of workers is small, and the efficiency is high; the granulation quality is improved; energy consumption is low.

Description

technical field [0001] The invention relates to a screen changing device, in particular to a fast manual screen changing device for plastic PVC granulation. Background technique [0002] At present, the existing screen-changing structure for plastic PVC granulation on the market generally uses manual disassembly of the fixed flange after shutdown, and replacement and cleaning of the filter plate after support. The disadvantages are long operating time, low mechanization work, low reliability, and manual Heavy workload, high energy consumption and low efficiency. Contents of the invention [0003] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a quick manual screen changing device, which realizes quick release and quick buckle through the Huff structure, with reliable structure, easy operation, small manual workload and high efficiency. [0004] In order to solve the problems of the technologies described above, th...
