And composition of the type of system
1. The type of system 
    Set containers loaded pneumatic conveying the classification, in addition to container tube into the type of non-wheeled and two wheeled, also by the pressure of three points: ① send-smoking. Roots blower that is used in the pipeline have a negative pressure inside the cylinder so that the container movement. ② pressure-sent. In the pipeline using compressed air cylinder so that the container movement. ③ mixed. The device in the pipeline system at one end of positive, negative pressure at the other end, so that the container under pressure in the cylinder movement, or assembled in the positive role of the cylinder movement, movement to return to the use of negative pressure. 
     Pressure-assembled containers pneumatic conveying the pressure on the transport sub-low voltage, medium voltage, three high-pressure, low pressure following 1OKPa; pressure in the following 50KPa; high pressure over 50KPa, mining air compressors were delivered up to the pressure 200-300KPa. There are types of systems from single-tube and twin-tube and from the two major categories, specific types of systems are often the following: 
     (1) and from the one-tube-style: the use of a pipeline to transport back and forth. Sending and receiving stations of the two inter-connected with a pipeline of the most simple form. 
     For fans to and from the single-tube connection. System by sending stations, receiving stations, Cha Dao, switching valve, and the exchange of stations by Fan components. By switching to and from the valve to the fans Inspiratory pressure and to achieve the gas exchange. Container sent by the tube station, then switch so that the valve in a negative pressure inside the pipe, connected in a state of Cha Dao (the other is accepted stations remained closed), assembled with the airflow into the cylinders while the exchange stations, as the exchange stations Both ends are connected with the gas source. As a result, when assembled into the tube station when the exchange will not be affected and in a state of balance, once assembled into the tube station exchange, the electronic control system at this time so that the electromagnetic valve switch moves by the fans for inspiration for the gas pressure, Cha Dao cut off access to the original conversion Access to delivery, the container tube of compressed air delivery Betty Drown then sent to another station, the container unloaded when the tube to cut off power supply fan. 
     Two fans of the loop, two fans to and from the exchange to achieve, at the same time, the work of the fan is not air entrance. 
     (2) interconnection between the one-tube-style: the interconnection of the above-actually two-unit plant expansion. 
     (3) one-tube-bearing group interconnection: Interconnection is a combination of further expansion, the point of contact with each other more. Is to connect the two systems with a tube connecting the conversion. According to the connection can have different serial and parallel connections to connect law. 
     (4) and from the double-tube: the sending and receiving two separate pipelines to achieve. Two by two be changed to a long tube, sending and receiving, respectively resettlement. By a suction fan or air pressure to achieve the tube container transport. 
     (5) dual-interconnection: Interconnection and the one-tube-like, pipe interconnection double-double-round-trip is the expansion of the type. 
     The points with two-pipe connections between the use of fixed points, or pneumatic control devices to achieve the points between the non-delivery point. He interconnection with the one-tube-like difference is, assembled in the tube ppeline in the direction of a fixed transportation. 
     (6) dual-focus on distribution: the central station to send and receive through the pipeline by collecting a, b, c, d, the hubs of the tube container, and then by the man at the center of hubs and sent through the pipeline to send, receive appropriate to start The fan stops and reality. It interconnection with the dual-contrast, the control system greatly simplified and also cause a significant increase in flexibility. 
     (7) to choose exchange-gravity: assembled a pipeline from the cylinder to another center of the mobile characteristics of the process, can be divided into gravity-option exchange and the exchange of machine-choice, and so on. Here are introduced to choose exchange-gravity. The device will have to send all of the above arrangement of pipes will be assembled by the top tube to guide the center tube to receive all the layout below, it seems as "x" shape. Cha Dao 7 by the composition of the chute, guide-tube fitted into the pipe to receive a term of 8, in order to pressure management to separate paragraph, sending pipe valve set to send, receive in the valve control set to receive, then send control fan The mouth breathing, and then to receive control of the air blower, in the "x"-shaped intersection equivalent to atmospheric pressure, in order to open the valve. Container sent Valves through the tube, close to the role of the switch, sent the signal to reach tube container, if "x" is the point of open, it switches close to the notice, sent in possession of the container will be out of control and separation equipment cited To the handover point. In between, can be used pneumatic brake or mechanical methods, so that the container tube down to the speed of 3-4m / s, Cha Dao is a two-way valves to regulate the possession of receiving about direction. 
     The design of these systems that send and receive possession of the pipeline can be implemented in different ways to connect transportation. They are electric or pneumatic automatic control device control 
     Purchase, in the choice of systems must take into account the characteristics of the system control logic.

If only the transmission characteristics of the process point of view, the system of choice points table
The choice of system design elements (suction pressure and send-send-comparison)

The working principle
    The device is the use of the pipeline within the rapid adoption of the compressed air generated by air flow to promote a strong box and the box-like items. The operator simply on the box-like launch pad, then press the start button, this time through a computer program detected automatically sent after the procedure, accompanied by a minor, "snapped" out of the box-like channel will be automatically sent to a few seconds Counter transceivers will reach the other side (the distance of transportation, as the length of time, the general rate of 5-30m / s), time to send and receive both the indicator light turn on the cabinet, has prompted been sent with the other party has received the box-like signal. To reach the other side of the box-like automatically fall into the box to receive, equipment and accompanied by "Di, Di," prompted the sound at this time, a process that the end of the conveyor.

Technical parameters

Technical characteristics 

• According to the requirements of production can be loaded with a variety of models and specifications of the material assembled a barrel.
•  Assembled at both ends of the plastic barrels can rapid replacement.
•  Can create double-sealed container barrels, or liquid materials inside the drums, outside the barrel attached to the inside of a single product for testing to meet the test samples with a single simultaneous arrival.
•  Long-distance signal transmission can be detected when the tracking device in the control room at any time in order to understand the kind of box to reach the specific location.
