A wind box type pipeline commutator

Abstract

The invention discloses an air box type pipeline commutator, which comprises an inlet end joint connected with the blower and a diverging end joint communicated with a plurality of transceiver stations, and also includes: a truncated cone connected to the inlet end joint Wind box; one end communicates with the wind box, and the other end can communicate with different joints of the branching end joints, and the inside of the blowing tube is provided with a blowing valve that can be opened along the blowing direction; the suction tube connected in parallel with the end of the blowing tube , the inside of the suction pipe is provided with a suction valve that can be opened along the suction direction, and the blowing pipe and the suction pipe can rotate synchronously with the wind box so that the blowing pipes are respectively connected with different split end joints; control the rotation of the blowing pipe and the suction pipe drive unit. The air box type pipeline commutator provided in the present invention realizes the functions of the bypass pipe and the pipeline commutator at the same time, no additional parts are needed, the volume of the whole device is reduced, and the arrangement of the blowing pipe and the suction pipe in parallel enables It can play the role of deceleration and buffer when inhaling gas delivery.

Description

technical field [0001] The invention relates to the technical field of pneumatic pipeline transmission, in particular to an air box type pipeline commutator. Background technique [0002] Pneumatic pipeline transmission system is a kind of logistics transmission system, which mainly uses the positive and negative air pressure generated in the fan to transmit the air conveyor; the air conveyor is generally a cylindrical bottle that matches the size of the conveying pipeline, and contains the samples to be tested, Or carry cash, etc., widely used in drug detection in hospitals, transportation of bank cash, cash collection at high-speed intersections, coal detection and other chemical and food detection fields. , the whole process is controlled by air pressure and reversing device, personnel cannot touch the transported items, ensuring the safety of the transport process. [0003] The pipeline commutator is a key component of the pneumatic pipeline transmission system. It is m...

Problems solved by technology

[0004] Due to the irregular shape of the S-shaped hard tube, it is not easy to produce and the cost is relatively high. At present, the production method of the S-shaped hard tube in the market is to cut the molded 90° large-arc PVC pipe or stainless steel pipe and then splice it back. , the cost of mold opening is high, and the accuracy of the finished product after reverse spelling is not easy to grasp, and the cost rate is low

S-shaped hard tube is not easy to process, and it is difficult to guarantee the outer dimension and roundness, so it is prone to bottle jamming, which greatly reduces the efficiency of transportation.
