Description
One, technical field
The present invention relates to a kind of powdery material sampling device, especially a kind of powdery material sampling device that uses air pressure in conveyance conduit, to carry that is applicable to.
Two, background technology
The material sampling is the progressive checking to the quality of a collection of goods and materials, thereby guarantee to use the processing quality of this batch goods and materials, therefore the material sampling is that a step must an indispensable link, particularly in electricity power enterprise, when using the conveying powdered coal of conveyance conduit, to the quality sampling analysis of coal in the conveyance conduit, thereby the parameter of adjustment generating set plays very important effect to the service efficiency that improves coal; Carrying the sampling method of coal at existing conveyance conduit mainly is hand sampling, because the conveyance conduit temperature is higher, be unfavorable for hand sampling, it is exactly the existing mechanical sampler, owing to use the direct horizontal string of sampling pipe in conveyance conduit, conveying to coal has produced very big resistance, the serviceable life of having reduced sampling pipe simultaneously.
Three, summary of the invention
In order to overcome above-mentioned technological deficiency, the purpose of this invention is to provide a kind of powdery material sampling device, little to the transporting resistance of powder, improved serviceable life.
For achieving the above object, the technical scheme that the present invention takes is: include conveyance conduit sidewall, master shield, secondary baffle plate, support, telescopic oil cylinder, get flitch and get material container; The conveyance conduit sidewall is provided with the slotted eye that coincide with master shield and secondary baffle plate, master shield and secondary baffle plate be set to form fan-shaped and its fan-shaped slotted eye that is embedded in the conveyance conduit sidewall in and side walls hinged with conveyance conduit on lateral cross section, master shield and secondary baffle plate are formed and are provided with fan-shaped cavity between fan-shaped, be provided with an end in fan-shaped cavity in the bottom of secondary baffle plate, the other end is at the flitch of getting in the secondary baffle plate outside, the secondary baffle plate of getting the top of flitch is provided with discharging opening, getting material container is arranged on the discharging opening place of secondary baffle plate and makes and get flitch and be arranged in the cavity of getting material container, getting material container is set to and the detachable sealed attachment of secondary baffle plate, support is arranged on the upper lateral part of secondary baffle plate and is set to and is fixedly connected with the conveyance conduit sidewall, and an end of telescopic oil cylinder is set to that the hinged and other end is set to secondary baffle plate hinged with support.
When not taking a sample, telescopic oil cylinder shrinks, and the slotted eye of master shield and conveyance conduit sidewall is tightly connected, when sampling, telescopic oil cylinder stretches out, the slotted eye of secondary baffle plate and conveyance conduit sidewall is tightly connected, and the powder in the conveyance conduit enters fan-shaped cavity under gas pressure, gas velocity in fan-shaped cavity is reduced, powder is dropped to get on the flitch,, enter into and get material container by discharging opening; Because the effect of fan-shaped and fan-shaped cavity, when sampling, it is little to account for the conveyance conduit space, little to the delivery air influence, therefore little to the transporting resistance of powder, has improved serviceable life.
The present invention has designed, and gets flitch and is set to be slidingly connected with secondary baffle plate.The density that has adapted to different gas pressure and high flow rates and different powders is got on the flitch easier the dropping to of powder sampling.
The present invention has designed, and also includes stopper, and the side that fan-shaped cavity top is provided with stopper and its position is provided with air hole.Make secondary baffle plate and conveyance conduit sidewall better tightness.
Four, description of drawings
Accompanying drawing is a synoptic diagram of the present invention.
Five, embodiment
Accompanying drawing is one embodiment of the present of invention, specifies present embodiment in conjunction with the accompanying drawings, includes conveyance conduit sidewall 1, master shield 2, secondary baffle plate 3, stopper 4, support 6, telescopic oil cylinder 7, gets flitch 8 and get material container 9; Conveyance conduit sidewall 1 is provided with the slotted eye that coincide with master shield 2 and secondary baffle plate 3, master shield 2 and secondary baffle plate 3 be set to form fan-shaped and its fan-shaped slotted eye that is embedded in conveyance conduit sidewall 1 in and hinged with conveyance conduit sidewall 1 on lateral cross section, master shield 2 and secondary baffle plate 3 formed and is provided with fan-shaped cavity between fan-shaped, the side that fan-shaped cavity top is provided with stopper 4 and its position is provided with air hole, be provided with an end in fan-shaped cavity in the bottom of secondary baffle plate 3, the other end is got flitch 8 secondary baffle plate 3 outsides, getting flitch 8 is set to be slidingly connected with secondary baffle plate 3, the secondary baffle plate 3 of getting the top of flitch 8 is provided with discharging opening, getting material container 9 is arranged on the discharging opening place of secondary baffle plate 3 and makes and get flitch 8 and be arranged in the cavity of getting material container 9, getting material container 9 is set to and secondary baffle plate 3 detachable sealed attachment, support 6 is arranged on the upper lateral part of secondary baffle plate 3 and is set to and is fixedly connected with conveyance conduit sidewall 1, and an end of telescopic oil cylinder 7 is set to support 6 hinged the and other end and is set to secondary baffle plate 3 hinged.
