The automatic receive-transmit system of air sample transporting
Technical field
The present invention relates to a kind of sample transfer means, more particularly relate to the automatic receive-transmit system of a kind of air sample transporting.
Background technology
In the large-scale production of steel mill, need analyze the product of producing, analytical sample need send to the analysis room or the laboratory is detected and analyzed.Common used transfer equipment is formed and is comprised sending station (being production scene or on-site sampling chamber), receiving station's (analyzing or the laboratory), conveyance conduit, pneumatic transmission and power source equipment and electric controling part.The pipeline of existing air sample transporting equipment and conveying equipment match ratio are more single, if the conveyance conduit radius strengthens, then reduce transporting velocity easily, and method of shipment and power source configuration are all more single.And present product analysis laboratory mostly is located at the place far away from the production scene, can grow the conveying style of distance, and guarantee certain transporting velocity, is that air sample transporting equipment needs improved energetically place.
Summary of the invention
In order to address the above problem, the invention provides the automatic R-T unit of a kind of air sample transporting, guarantee travelling speed at a high speed, various method of shipment and power source configuration flexibly, and can carry out manual and the conversion of operation automatically, be fit to the length distance High-speed and carry style.
The automatic receive-transmit system of a kind of air sample transporting, comprise on-the-spot substation and analysis room master station, and the conveyance conduit between connecting, described on-the-spot substation and analysis room master station all comprise the transmitting-receiving cabinet, and the volume adjusting apparatus that is connected with described transmitting-receiving cabinet, described volume adjusting apparatus connects oil-water separator and gas-holder by air duct successively, also is provided with exhaust apparatus, pressure relief device and photoelectric detection system successively on the conveyance conduit that described transmitting-receiving cabinet top connects.
The case bucket that the conveyance conduit intersection point place that described transmitting-receiving cabinet comprises R-T unit, be connected with described R-T unit connects, described case bucket also connects described air duct;
Described on-the-spot substation, analysis room master station are connected by telecommunication cable with photoelectric detection system;
Described transmission cabinet is equipped with the metal proximity transducer;
Described gas-holder configuration power source, power source can be a kind of in high pressure positive blower, air compressor and the pipeline air compressor.
Beneficial effect of the present invention is: utilize compressed-air actuated pressure to promote the sample box and move in conveyance conduit, reach the purpose of on-the-spot sample delivery to analysis room master station, substation and analysis room master station carry out transmitted in both directions at the scene, and be simple to operate, safe and practical, the control reliability height.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Be illustrated in figure 1 as structural representation of the present invention, the automatic receive-transmit system of a kind of air sample transporting, comprise on-the-spot substation and analysis room master station, and the conveyance conduit 6 between connecting, described on-the-spot substation and analysis room master station all comprise transmitting-receiving cabinet 1, and the volume adjusting apparatus 8 that is connected with described transmitting-receiving cabinet 1, described volume adjusting apparatus 8 connects oil-water separator 9 and gas-holder 2 by air duct 7 successively, also is provided with exhaust apparatus 3, pressure relief device 4 and photoelectric detection system 5 successively on the conveyance conduit 6 that described transmitting-receiving cabinet 1 top connects.
The case bucket that the conveyance conduit 6 intersection point places that described transmitting-receiving cabinet 1 comprises R-T unit, be connected with described R-T unit connect, described case bucket also connects described air duct 7; Described on-the-spot substation, analysis room master station are connected by telecommunication cable with photoelectric detection system; Described transmission cabinet is equipped with the metal proximity transducer; Described gas-holder 2 configuration power sources, power source can be a kind of in high pressure positive blower, air compressor and the pipeline air compressor.
When the present invention carried sample again, the chamber door that will send the dispensing device in the cabinet 1 was earlier opened, and sample box is placed in the dispensing device, and sample box enters in the case bucket, door closure.By the air pressure in the control gas-holder 2, to regulate volume adjusting apparatus 8 and open, the sample box is transferred.When the sample box passes through to arrive photoelectric detection system 5, promptly detecting sample box device arrives, at this moment arriving instruction reflects by PLC, make on-the-spot substation gas-holder 2 air valves close (stopping air feed), the sample box drops to transmitting-receiving cabinet 1 top of analysis room master station, send the metal proximity transducer of installing cashier's office in a shop and receive signal, on controller, demonstrate sample and reach, operator's taking-up sample of just can uncapping.
Total system is by electrical control, can be on computer screen the operation conditions of Direct observation display system, the source of sample, the delivery status of sample, and the arrival cue of sample.The sample box accepts to realize " soft landing ".Utilize pressure release gas circuit, continuous the blowing of time-delay effectively to brake to carrying the sample box with the blowback gas circuit, make the sample box steadily drop down onto the transmitting-receiving cabinet, reduced of the impact of sample box greatly to equipment, reduced noise, the equipment noise is in Yi Michu≤60 decibel, improve the reliability of complete machine, can come transmission back between on-the-spot substation and the analysis room master station simultaneously, improved the interaction between scene and the analysis room.
