Embodiment:

Describe embodiment in detail in conjunction with above accompanying drawing: stuff level switch 15 is fixed on the tackiness agent filling container 14, be connected with pipeline on the tackiness agent filling container, be connected with a material-handling pump 13 on it, send conveyance conduit to draw two supply pipes from thing and be connected with A respectively, temporary jar 18 of B, 19 at A, on the materail tube of the inlet that B is temporary jar A is housed respectively, B jar feeding valve 9,11, draw a drainage conduit and suction booster 16 connections on the Material pipeline again respectively, on its drainage conduit A is housed, B jar blow-off valve 10,12, A, A is equipped with on the top that B is temporary jar, B sensor 7,8 go up input point with PLC connects, A, the side that B is temporary jar has an evacuation port, connect by emptying pipe and compressed air hose 2, another road and emptying pipe 1 are connected, A, be respectively equipped with A on the emptying pipe that B is temporary jar, B jar exhaust-valve 3,5 and pressure charging valve 4,6, the other end is connected for temporary jar 20 by pressure inlet and high pressure on the suction booster, and pressure transducer 22 is contained in the ingress of temporary jar of high pressure and connects by pipe and main delivery pipe 21.Main sending being connected to the tackiness agent outer pipe and connecting with tackiness agent outlet 27 on the pipeline 21, the pipe on pressure surge tank 23 (see figure 2)s export is contained in the centre of high-pressure buffer valve 24 and tackiness agent supply valve 26, at the end of pipe pressure transducer 25 is housed.When system moves, by manually adding tackiness agent to tackiness agent filling point 14, system PLC judges through the stuff level switch 15 of tackiness agent filling point: A keeps in jar 18 charging flow processs, closes blow-off valve 10, close feeding valve 11, open feeding valve 9, close pressure charging valve 4, open exhaust-valve 3 and start material-handling pump 13, tackiness agent is sucked a temporary jar A18, when sensor 7 detects material level and reaches, close feeding valve 9, close material-handling pump 13, close exhaust-valve 3, the temporary jar charging of A finishes, and enters preprocessing process.The working method that B is temporary jar 19 is identical with the temporary jar of A to be to carry out carrying out alternation with the temporary jar of A in order to raise the efficiency.Keep in jar 18 workflows through flow process, the A that carries out the board high-pressure delivery after the pretreatment: open blow-off valve 10 and open pressure charging valve 4, start suction booster 16, open supercharging feeding valve 17, be transported to high pressure temporary jar 20, when pressure transducer 22 detects pressure and reaches predetermined value, close feeding valve 17, close suction booster 16, be transported to each tackiness agent by main delivery pipe 21 and use point.The process of the storage of higher pressures above when pressure transducer 22 detects the pressure reduction, repeating.Tackiness agent uses the workflow (accompanying drawing 2) of point: carry 21 by main, arrive the tackiness agent that uses point and use the subordinate machine system of point by using the some opening and closing, open the time stage system when extension set and open high-pressure buffer valve 24, tackiness agent enters pressure surge tank 23, behind the predefined value that reaches pressure transducer 25, close the high-pressure buffer valve, simultaneously according to the control opening and closing tackiness agent supply valve 26 that uses point sensor.
