Abstract

The utility model discloses a polyurethane coating conveying pipeline with a filtering function, which comprises a connecting pipe, wherein a first conveying pipe is arranged at a feed inlet of the connecting pipe. The utility model has the beneficial effects that the two filter screen plates are symmetrically arranged on the two back-shaped connecting pipes by arranging the back-shaped connecting pipe between the first conveying pipe and the second conveying pipe, and simultaneously arranging the alternate blocking mechanism consisting of the rack, the gear, the motor, the vertical plate, the linkage rod and the blocking plate on the back-shaped connecting pipe, so that the polyurethane coating can be removed in the conveying process under the action of the filter screen plates in the conveying process, and after one filter screen plate is blocked, the corresponding blocking plate on the alternate blocking mechanism is blocked alternately, thereby realizing the switching of the conveying channel on the back-shaped connecting pipe, realizing the use of the other filter screen plate and ensuring the efficient filtering and conveying of the polyurethane coating.

Description

Polyurethane coating conveying pipeline with filtering capability Technical Field The utility model relates to the technical field of polyurethane paint conveying, in particular to a polyurethane paint conveying pipeline with a filtering function. Background When the polyurethane paint is conveyed in the spraying process, impurities in the polyurethane paint need to be removed in time in the conveying process of the polyurethane paint in order to ensure the final spraying quality of the polyurethane paint. At present, the pipeline for conveying polyurethane paint mainly comprises a straight-through circular pipe, and the conveying pipeline with the structure can convey the polyurethane paint, but the polyurethane paint can be sprayed and used only by additionally filtering the polyurethane paint by means of a filtering mechanism after conveying, and the high-efficiency conveying and use of the polyurethane paint are inconvenient because the conveying process and the filtering process are discontinuous, and meanwhile, the risk that the polyurethane paint cannot be conveyed normally due to the fact that the conveying pipeline is blocked by impurities exists. Disclosure of utility model First, the technical problem to be solved The utility model aims to solve the technical problem of providing a polyurethane coating conveying pipeline with a filtering function aiming at the current state of the art. (II) technical scheme The utility model provides a polyurethane paint conveying pipeline with a filtering function, which comprises a connecting pipe, wherein a conveying pipe I is arranged at a feed inlet of the connecting pipe, a conveying pipe II is arranged at a discharge outlet of the connecting pipe, the connecting pipe is of a back-shaped structure, two filter screen plates are symmetrically arranged on the connecting pipe, an alternate blocking mechanism is arranged between the two filter screen plates on the connecting pipe, and the alternate blocking mechanism comprises a rack, a gear, a motor, a vertical plate, a linkage rod and a blocking plate. Furthermore, the first conveying pipe and the second conveying pipe are in threaded connection with the connecting pipe, and sealing parts are arranged at the connection parts of the first conveying pipe, the second conveying pipe and the connecting pipe. Further, the filter screen plate is connected with the connecting pipe through a screw, and a sealing gasket is arranged at the contact part of the filter screen plate and the connecting pipe. Further, the vertical plate is arranged on one side in the connecting pipe through bolts, and the motor is arranged on the upper part of one side wall of the vertical plate. Further, the gears are arranged on the power output shaft of the motor, two racks are respectively meshed with two sides of the gears. Further, the linkage rod is welded at the bottom end of the rack, and the blocking plate is connected at the bottom end of the linkage rod. Further, the plugging plate is in sliding sealing connection with the upper part of the connecting pipe, and the plugging plate is of an I-shaped structure. (III) beneficial effects Compared with the prior art, the utility model has the following beneficial effects: According to the utility model, the two filter screen plates are symmetrically arranged on the two back-shaped connecting pipes, and the alternate blocking mechanism consisting of the rack, the gear, the motor, the vertical plate, the linkage rod and the blocking plate is arranged on the back-shaped connecting pipes, so that the polyurethane coating can be removed in the conveying process under the action of the filter screen plates in the conveying process, and after one filter screen plate is blocked, the corresponding blocking plate on the alternate blocking mechanism is blocked alternately, so that the switching of a conveying channel on the back-shaped connecting pipe is realized, the use of the other filter screen plate is realized, and the efficient filtering conveying of the polyurethane coating is ensured.
