Description
Technical field
The utility model relates to a kind of system that utilizes air-flow to transmit cargo ticket in pipeline.
Background technology
The applicant has applied for that to Patent Office of the People's Republic of China name is called " cargo ticket pipe transmission system " on October 23rd, 2009, number of patent application is 200920247497.1 utility model patent, specifically be that a transmit receive unit respectively is set in first and second two places, between two transmit receive units, delivery duct is set, change-over valve and blower fan (pumping plant) are set to ground therein such as first.When from first ground transport box to second during ground, blower fan blows out in delivery duct by the positive draft of first to second, promote container from first ground to second ground; Otherwise blower fan blows out back draught in delivery duct, forms negative pressure, and container is inhaled to first ground from second ground.As seen the air pressure that forms in pipeline is to be finished by a blower fan that is arranged on a ground, and formed air pressure is limited, and correspondingly the length of the delivery duct of this system also is restricted, and generally is no more than 2500 meters.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of length apart from the cargo ticket pipe transmission system.
The purpose of this utility model is achieved in that a transmit receive unit respectively is set in first and second two places, between two transmit receive units, delivery duct is set, it is characterized in that: a pumping plant is respectively established in first and second two places, this pumping plant is to be hinge with the change-over valve, four mouths of change-over valve connect respectively: local porting, local fan wind inleting tube, local blower fan air outlet tube mouth, air supply line, the another port of air supply line connects the check valve in the local transceiver device, between air supply line and delivery duct, check valve is set, this check valve is arranged on the upper end of local transceiver device, and direction is to lead to air supply line by delivery duct; Delivery duct is formed by the first and second two sections, is connected by threeway between two sections delivery ducts, and another of threeway be atmosphere all, and an electro-optical tubes or sensor respectively are set in the delivery duct of threeway both sides.The mouth of electro-optical tubes or sensor is connected with PLC (Programmable Logic Controller) input end, and PLC controls the blower fan rotation of first and second two places.
Working process is: the container that cargo ticket will be housed when needs is when first ground transmit receive unit is transferred to second ground transmit receive unit, blower fan blows out positive draft by change-over valve to the first section of first ground transmit receive unit and delivery duct, container is blown to threeway along first section delivery duct, container triggers first electro-optical tubes, first electro-optical tubes requires second ground fan starting to PLC output control signal, second ground fan starting, back draught enters second section delivery duct from threeway; Container by threeway after the positive draft of first section by the threeway pressure release.The back draught of second section promotes container and enters second section delivery duct and trigger second electro-optical tubes, and second electro-optical tubes requires first ground blower fan to shut down to PLC output control signal.When walking to transmit receive unit top, second ground, container falls into second ground transmit receive unit by gravity, back draught is through the check valve and the air supply line on second ground, and the pumping plant that enters second ground promptly drains into atmosphere through change-over valve, fan air inlet, blower fan exhausr port and the porting on second ground successively.
The container that cargo ticket will be housed when needs is when second ground transmit receive unit is transferred to first ground transmit receive unit, and working process is with above-mentioned opposite.
Compared with prior art, the beneficial effects of the utility model are: it is provided with two pumping plants in first and second two places, and container is carried by the pipeline relay that forms positive draft and back draught, delivery stroke is added be twice.

Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is a scheme drawing of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the enlarged drawing of pumping plant 61 among Fig. 2.
Fig. 4 is the enlarged drawing of pumping plant 62 among Fig. 2.
The specific embodiment
Referring to Fig. 1 and 2, a transmit receive unit 11 and 12 respectively are set in first and second two places, delivery duct 31 and 32 are set between two transmit receive units, a pumping plant 61 and 62 are respectively established in first and second two places, referring to Fig. 3, with first ground pumping plant 61 is example, and pumping plant 61 is to be hinge with change-over valve 613, and four mouths of change-over valve connect respectively: the air inlet pipe 615 of first ground porting 614, first ground blower fan 611, first ground blower fan discharge pipe 612, air supply line 71.The another port of air supply line 71 connects the check valve in the first ground transmit receive unit 11, between air supply line 71 and delivery duct 31 check valve 21 is set, and this check valve 21 is arranged on the upper end of first ground transmit receive unit, and direction is to air supply line 71 by delivery duct logical 31.Referring to Fig. 4, second ground pumping plant 62 is identical with first ground pumping plant 61, no longer repeats; Delivery duct is formed by the first and second two section 31 and 32, and two segment length are identical, is connected by threeway 5 between two sections delivery ducts, and another of threeway crossed filtering installation 51 logical atmosphere all, and an electro- optical tubes 41 and 42 respectively are set in the delivery duct of threeway both sides.The mouth of electro-optical tubes is connected with PLC (Programmable Logic Controller) input end, and a PLC controls the blower fan rotation of first and second two places, and two PLC also can be set, and each controls a typhoon machine.
