Air flow crusher system and blocking-removal-type connecting pipe thereof

Abstract

The invention discloses an air flow crusher system and a blocking-removal-type connecting pipe thereof. The problem of powder blocking in a pipeline is solved. According to the key points of the technical scheme, the blocking-removal-type connecting pipe comprises a pipe body, a volute groove is formed in the inner wall of the pipe body, and the center of the volute groove is provided with the pipe body connected to a rotary shaft in a threaded mode; the upper end of the rotary shaft is arranged in the pipe body, and the lower end of the rotary shaft is arranged outside the pipe body; a sliding block is arranged in the volute groove in a slipping mode, and a material sweeping assembly is hinged between the sliding block and the upper end of the rotary shaft; when rotary shaft rotates and rises and falls around athread, the sliding block rotates around the volute groove so as to achieve umbrella-shaped closing up and propping open of the material sweeping assembly; the pipe body is provided with a power assembly for driving the rotary shaft to rotate in the forward and reverse directions so as to achieve vertical rising and falling of the rotary shaft around the thread of the pipe body, and the power assembly comprises a gear set connected to the lower end of the rotary shaft and a power source for driving the gear set; and through propping open and closing up of the material sweeping assembly in the pipe body in a rotating mode, the purpose of removal of blocking of accumulated materials at the connecting pipe is achieved.

Description

technical field [0001] The present invention relates to a pulverizer and a connecting pipe, more particularly, it relates to a jet pulverizing system and a plug-breaking connecting pipe thereof. Background technique [0002] Jet mill, cyclone separator, dust collector and suction fan form a complete set of crushing system. After the compressed air is filtered and dried, it is sprayed into the crushing chamber at a high speed through the Laval nozzle. At the intersection of multiple high-pressure airflows, the material is repeatedly collided, rubbed and sheared and crushed. The crushed material rises with the action of the fan. The airflow moves to the grading area under the strong centrifugal force generated by the high-speed rotating grading turbine. [0003] The pulverized material flows to the upper end of the separator through the ascending pipeline for falling separation; the pulverized material moves from bottom to top under the suction of the suction fan; and when a ...

Problems solved by technology

[0003] The pulverized material flows to the upper end of the separator through the ascending pipeline for falling separation; the pulverized material moves from bottom to top under the suction of the suction fan; The powder is easy to spit out quickly and intensively, so that the powder suction flow rate of the suction fan is smaller than that of the pulverizer, and the pipeline is connected to the outlet end of the pulverizer—that is, the low station end. The blockage of the blocked pipes, due to the lack of air circulation, makes it difficult for the suction fan to induce air normally. In the airflow crushing of rice noodles at the processing site, blockages occur once every half an hour on average.
