Problems solved by technology

In order to provide two airflows in opposite directions, it is usually necessary to configure two fans for the conveying pipeline. The investment cost of the equipment is relatively high, and during the conveying process, one fan is always running and the other is on standby, so the utilization rate of the equipment is not high.
[0003] Chinese patent CN102900866B discloses an air-to-air valve. Although the air-to-air valve can also adjust the airflow direction flowing through the material delivery pipeline, in the scheme disclosed in thi

Abstract

The invention provides a reversing mechanism of a pneumatic conveying system, and the pneumatic conveying system. An inner cavity of a shell of the reversing mechanism is divided into three cavities through a first partition board (111) and a second partition board (112), the first partition board (111) is provided with a first inner cavity opening (126), and the second partition board (112) is provided with a second inner cavity opening (127); the outer wall of the shell is provided with an air outlet (121), an air inlet (122), a ventilation opening (123), an air suction port (124) and an airblowing port (125); the reversing mechanism (100) further comprises a reversing execution assembly capable of blocking the air suction port (124) and the second inner cavity opening (127) at the sametime, so that a material conveying pipeline (400) can obtain positive pressure; and meanwhile, the reversing execution assembly can block the air blowing port (125) and the first inner cavity opening(126) at the same time, so that the material conveying pipeline (400) obtains negative pressure. According to the reversing mechanism, the flowing direction of airflow in the reversing mechanism is adjusted as needed, so that bidirectional conveying of materials is achieved.

Description

technical field [0001] The invention relates to the field of pneumatic conveying, in particular to a pneumatic conveying system capable of forwardly and reversely conveying materials and a reversing mechanism of the pneumatic conveying system. Background technique [0002] In the application of pneumatic pipeline transportation, it is usually required that a certain transportation pipeline can have both the function of forward transportation and the function of reverse transportation. direction movement. In order to provide two airflows in opposite directions, it is usually necessary to configure two fans for the conveying pipeline. The input cost of the equipment is high, and during the conveying process, one fan is always running and the other is on standby, so the utilization rate of the equipment is not high. [0003] Chinese patent CN102900866B discloses an air-to-air valve. Although the air-to-air valve can also adjust the airflow direction flowing through the materia...
