Abstract
A controllable aligning sample admitting device, comprising a fixation seat, a handspike, a sample admitting boat and an aligning moving organ, characterized in that: the aligning moving organ is the gear and rack moving organ that is driven by the electric machine, which is also provided with the control circuit. The rack moves in the guide cover of the fixation seat, and its starting and stopping locations are controlled by the travel switch. The rack connects with the sample admitting boat through the connecting rod and the handspike and the outer side of it is provided with a photoelectric coupler and the middle part of it is provided with an anti-dazzling screen. The utility model is applied for delivering the coal samples into the depolymerizing furnace when measuring the sulphur content in the coal. The starting and stopping locations of the sample admitting boat and the location where it reaches the high and low temperature regions in the depolymerizing furnace and the staying time can be automatically controlled. The whole sample admitting process is continuous, accurate with good reliability and high working efficiency.
Description
Technical field
The utility model relates to a kind of being used for measuring the sampling device of its constituent content behind the thing sample Pintsch process, especially for the controllable type straight line sampling device of measuring element sulphur content in the coal.
Background technology
, must be advanced to coal sample in 1150 ℃ the high-temperature cracking furnace in assay determination coal during element sulphur content according to dynamic coulomb principle, allow its abundant combustion decomposition, need use the straight line sampling device.In the past, the sampling device of employing be by the driven by motor pulley along two parallel orbit moving linearlies, pulley and cotton rope connect, cotton rope drives push rod, and sampling boat is sent into pyrolysis furnace.This device is not only made cumbersome, uses also derailing easily of top sheave, and the cotton rope firmness is also relatively poor, and the sample introduction position is by hand-guided, can not guarantee the sample introduction process continuously, accurately, reliability is bad, efficient is not high.
The utility model content
The technical problems to be solved in the utility model provides a kind of sample introduction that is used for coal element sulphur assay continuously, accurately, good reliability, the controllable type straight line sampling device of high efficiency.
The technical solution of the utility model is: controllable type straight line sampling device, comprise holder, push rod, sampling boat and straight-line motion mechanism, improvements are that described straight-line motion mechanism is by motor-driven gear, the tooth bar motion, tooth bar moves in the guide pin bushing of holder both sides, the holder outside has the control rack stroke to rise, the travel switch of dead-centre position, the tooth bar outside is provided with the photoelectrical coupler that is contained on the holder, two places, tooth bar middle part are provided with the anti-dazzling screen that can pass through photoelectrical coupler, above-mentioned motor, travel switch and photoelectrical coupler are electrically connected with control circuit.
Described tooth bar front end is rigidly connected by connecting link and push rod, and an end of push rod is enclosed within the through hole of sampling boat one end; The position of the set anti-dazzling screen in tooth bar middle part is corresponding with sampling boat high and low warm area present position in pyrolysis furnace; Tooth bar one side has gathering sill, guide finger.
Adopt above technical scheme, motor-driven gear rotation drive the sampling boat moving linearly with the tooth bar of gearing mesh by connecting link, push rod, and the connecting portion of push rod and sampling boat can be done certain rotation, make sampling boat that certain degree of freedom be arranged, motion is smooth and easy in the quartz ampoule of pyrolysis furnace.The position and the residence time of the rising of sampling boat, not-go-end point and the high and low warm area of arrival pyrolysis furnace, provide signal by travel switch and photoelectrical coupler, motor action is guaranteed, thereby make whole sample introduction process continuously, accurately by control circuit, good reliability, high efficiency.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is an A-A place cut-open view among Fig. 1.
Embodiment
Consult accompanying drawing, motor 10 is installed on the holder 8, and gear 9 tooth bar 5 interior with being through holder both sides guide pin bushing that is contained on the motor shaft is meshed.The tooth bar front and back ends is provided with banking stop 4, and there is travel switch 12 in holder two outsides.The tooth bar front end is rigidly connected by connecting link 3 and push rod 2, and an end of push rod becomes hook-shaped, is inserted in the through hole of sampling boat 1 one ends.Two places, tooth bar middle part are provided with anti-dazzling screen 6, and photoelectrical coupler 7 is contained on the holder.Tooth bar one side has gathering sill and guide finger 11.In this device, motor, travel switch, photoelectrical coupler all are electrically connected with control circuit.
Claims (4)
