Problems solved by technology
[0002] At present, in the material transportation or mixing equipment such as sand aggregate or concrete, elbow pipes are often used for conveying redirection. During the conveying process, the materials will be affected by the centrifugal force generated by the curved flow channel and the installation steps of the inner hole, etc., making the materials When the previous conveying pipe flows into the elbow, it does not flow forward smoothly, but more forward in a vortex shape, which makes the inlet end of the pipe suffer from complex forces and greater pressure, resulting in rapid wear and short life of the inlet end of the pipe. Once damaged , the entire fitting needs to be replaced

The invention discloses a split conveying hinge elbow. The elbow comprises an elbow body and an outer pipe body, the elbow body is provided with an inlet end and an outlet end, an inlet flange is fixedly arranged at the inlet end of the elbow body, the outlet end is connected with the outer pipe body, a detachable flange plate sleeves the inlet flange, a first wear-resistant sleeve is embedded inthe inner wall of the inlet flange, the inner diameter of the first wear-resistant sleeve is smaller than the inner diameter of the elbow body, a wear-resistant inner pipe is embedded in the inner wall of the outer pipe body, the end, far away from the elbow body, of the outer pipe body is fixedly provided with a connecting flange, and a second wear-resistant sleeve which is in butt joint with thewear-resistant inner pipe is embedded in the inner wall of the connecting flange. According to the design, the wear resistance and the impact resistance of the elbow are improved, the process cost and the manufacturing cost are saved, and the service life of the elbow is prolonged.
Description
technical field [0001] The invention relates to a conveying elbow, in particular to a detachable conveying hinge elbow. Background technique [0002] At present, in the material transportation or mixing equipment such as sand aggregate or concrete, elbow pipes are often used for conveying redirection. During the conveying process, the materials will be affected by the centrifugal force generated by the curved flow channel and the installation steps of the inner hole, etc., making the materials When the previous conveying pipe flows into the elbow, it does not flow forward smoothly, but more forward in a vortex shape, which makes the inlet end of the pipe suffer from complex forces and greater pressure, resulting in rapid wear and short life of the inlet end of the pipe. Once damaged , the entire fitting needs to be replaced. Contents of the invention [0003] The present invention aims to solve the above-mentioned technical problems at least to a certain extent. For this...
