Further specify technical scheme of the present invention below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of appearance dish among the present invention.
Fig. 3, Fig. 4 are respectively sample introduction sample-weighing devices and go out the different structure synoptic diagram of kind sample-weighing device among the present invention.
Embodiment
Referring to Fig. 1; The automatic total moisture tester of coal sample; The frame 1 that comprises a horizontally set, two of frame are respectively equipped with sample introduction sample-weighing device 2 and go out kind sample-weighing device 8, and the centre is provided with drying unit 6; Sample introduction, the top that goes out kind sample- weighing device 2,8 are respectively equipped with sampling device 3 and go out sampling device 9, the below of drying unit 6 be provided with said sampling device 2 with go out the coal sample transmitting device 4 that kind sample-weighing device 8 is connected.Coal sample transmitting device 4 adopts belt conveyors, comprises by motor-driven driving wheel 401, engaged wheel 403 and the conveying belt 402 on driving wheel 401 and the engaged wheel 403; Sampling device 3 with go out sampling device 9 and also adopt belt conveyor, on their belt 301,901, be respectively equipped with shifting block 302,902, be used to stir appearance dish 5 and move forward; Coal sample transmitting device 4, sampling device 3 and go out sampling device 9 and also can adopt conventional transport such as screw mandrel, rack-and-pinion, linear electric motors, electric pushrod or chain; Drying unit 6 comprises a cover body 601, is provided with heating 602 in the cover body 601, and the top of cover body 601 is provided with extractor fan 7; Heating 602 adopts ceramic infrared heater, also can adopt conventional electric heating device.The present invention also comprises appearance dish 5, and the two ends of appearance dish 5 (also can only at one end) be provided with and be used to load object to regulate the tubular chambers 501 of weight.
Principle of work:
The present invention is by automatic controlling system work: the appearance dish 5 that automatic feed transport (drawing) will be equipped with coal sample (about 1000g) is delivered on the sample introduction sample-weighing device 2; The weight of automatic weighing sample, completion is weighed, and sampling device 3 utilizes shifting block 301 that appearance dish 5 is pushed on the coal sample transmitting device 4; Coal sample transmitting device 4 by the program of computer settings with appearance dish 5 slowly from drying unit 6 through (speed of passing through can according to the customer requirements setting); Appearance dish 5 goes out sampling device 9 appearance dish 5 is shifted onto out on kind sample-weighing device 8, automatically the weight of weighing sample to the outlet of drying unit 6; Accomplish and claim appearance; Go out sampling device 9 appearance dish 5 is pushed away out the test that kind sample-weighing device 8 is accomplished a coal sample, simultaneously, computing machine calculates the content of coal sample total moisture automatically.
Because there is weight error in the appearance dish in manufacturing process, for fear of the trouble that when measuring coal sample moisture, needs the weight of each kind dish is carried out weighing one by one at every turn, the chamber 501 among the present invention on the appearance dish 5 can address this problem easily.All the weight of appearance dish is carried out weighing earlier; Coil as the standard sample dish with the heaviest appearance; Then according to the weight difference of various kinds dish and this standard sample dish; To clog with the object (bonding jumper, sheet etc.) of weight such as this difference and just can realize all unifications of appearance dish weight in the chamber 501 on the appearance dish 5, can guarantee the coal sample weight unanimity in the various kinds dish.
Sample introduction sample-weighing device 2 is as shown in Figure 3 with the structure that goes out kind sample-weighing device 8; Comprise a frame 10; The top of frame 10 is provided with movable platform 14 through 4 guide poles 15, and frame 10 is provided with motor jacking gear 11 and is connected with movable platform 14, and movable platform 14 is provided with electronic platform scale 13; Carriage 12 is located at electronic platform scale 13 tops, and it is corresponding with electronic platform scale 13 that carriage 12 is used for supporting appearance dish 5.When claiming appearance; Appearance dish 5 is shifted electronic platform scale 13 tops by automatic feed transport (picture) onto along carriage 12, and motor jacking gear 11 promotes movable platforms 14 and rises, and coils 5 to appearance and breaks away from carriage 12 fully; The stable reading of electronic platform scale more than 13 seconds; Completion is weighed, and motor jacking gear 11 drives movable platform 14 and falls back original position, accomplishes and once claims appearance automatically.
Sample introduction sample-weighing device 2 with go out also fixing electronic platform scale 13 of kind sample-weighing device 8, motor jacking gear 11 is connected with carriage 12 through support 16, the appearance dish 5 that goes up and down is realized automatically title kind, and is as shown in Figure 4.
Sampling device 3 with go out sampling device 9 and also can adopt other routine techniques such as rack-and-pinion; The sprocket wheel chain; Modes such as feed screw nut with automatic sampling apparatus be installed in appearance dish 5 around realize auto injection, also can with electric pushrod or linear electric motors be installed in appearance dish 5 around realize auto injection.
