For materials with a certain viscosity, the inner wall of the traditional rotary discharge valve is easily adhered by the material during operation, and it is difficult to clean it online. In the long run, the material will accumulate, causing material pollution, affecting the normal operation of the feeding equipment, and seriously causing equipment erosion. Utility Model Content
[0003] The utility model aims to overcome the deficiencies of the prior art and to provide a star-shaped rotary discharge valve which can realize self-cleaning of the equipment during the rotary feeding process.
[0004] A technical solution to achieve the above object is: a star-shaped rotary discharge valve, comprising a housing and a rotary drive assembly;
[0005] A main shaft is horizontally arranged in the shell, one end of the main shaft is connected to the rotating drive assembly, and the other end is connected to the sealing cover and the supporting device. A supporting rib is fixed on the outside of the main shaft, and a star-shaped blade is fixed on the supporting rib. The star-shaped blade is composed of a number of arc-shaped plates bent toward the center of the shell. The connecting part of any two adjacent arc-shaped plates is provided with a protruding structure pointing to the inner wall of the shell, and a scraper tangent to the inner wall of the shell is connected to the protruding structure. Two adjacent scrapers and the arc-shaped plate therebetween form a feeding interval; a feed port pipe is provided at the top of the shell, and a discharge port pipe is provided at the bottom of the shell.
[0006] Furthermore, the rotary drive assembly includes a motor, a reducer, a support frame, a motor cover and a supporting device and a motor mechanical seal.
[0007] Furthermore, the feed inlet pipe is connected to the feed inlet flange, and the discharge port pipe is connected to the discharge port flange.
[0008] Furthermore, the scraper is replaceably and adjustably connected to the protruding structure by bolts.
[0009] Furthermore, the scraper is provided with a plurality of adjustment holes, and when the scraper is installed on the protruding structure through different adjustment holes, the distance between the scraper and the inner wall of the shell is different.
[0010] The utility model discloses a star-shaped rotary discharge valve, which realizes rotary feeding by driving the rotation of the star-shaped paddles through a rotary drive assembly; a protruding structure of the star-shaped paddles pointing to the inner wall of the shell is provided with a scraper, which can scrape off the material adhered to the inner wall of the shell during the rotary feeding process, thereby realizing self-cleaning of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
