Detailed Description
A fully sealed push-pull sampler, substantially as described herein with reference to figures 1 and 2 of the accompanying drawings, wherein: the device comprises a push-pull rod 1, a connecting bolt 2, an upper cover 3, a shell 4, a sealing box 5, a locknut 6, a packing seal 7, a sealing gland 8, a material receiving box 9, a sealing gasket 10, a sample storage box 11 and a bolt 12.
In this embodiment, the front end of the housing 4 is provided with the upper cover 3, the rear end of the housing 4 is provided with the sealing box 5, the sample storage box 11 is connected below the housing, the material receiving box 9 is arranged in the housing 4, one end of the material receiving box 9 is connected with the push-pull rod 1 penetrating through the upper cover 3, and the sealing box 5 is connected with the material receiving box 9.
The diameter of the sealing box 5 is larger than that of the inner hole part with the same diameter at the rear end of the shell 4, which is provided with the material receiving box 9. The outer diameter of the material receiving box 9 is equal to the minimum inner hole diameter of the housing 4 in the length direction.
The volume of the sample storage box 11 is larger than that of the material receiving box 9; the connecting end of the shell 4 and the sample storage box 11 is in a cone-shaped structure.
The sealing box 5 is provided with a groove structure, and a sealing gasket 10 is arranged in the groove structure.
The upper cover 3 is connected with the front end of the shell 4 through a bolt, a through hole for the push-pull rod to pass through is formed in the rotation center of the upper cover 3, a packing seal 7 which is matched with the push-pull rod and the communication of the upper cover 3 is arranged in the through hole, the upper cover 3 is connected with a sealing gland 8 through a connecting screw rod 2, a locking nut 6 is arranged on one side of the sealing gland 8, and the locking nut 6 is matched with a thread structure on the push-pull rod 3.
The sealing filler 7 is provided with a threaded hole matched with the push-pull rod 3.
The outer diameter of the material receiving box 9 is equal to the equal-diameter structure of the shell 4 in the length direction, and a material receiving port is arranged on the side wall of the material receiving box 9 and is positioned at the radial 1/3-1/2 position of the material receiving box 9.
The sampler is arranged on a finished powder pipeline, and a shell 4 of the sampler is connected with the pipeline in a welding mode. A sealing gasket 10 is arranged at the root part of the sampler and is locked by a locking nut 6, so that silicon powder is prevented from entering a material receiver and leaking out along a push-pull rod in the operation process of equipment. And a packing seal 7 is arranged at the upper cover of the shell 4 to prevent the silicon powder from leaking out in the sampling process. The sampler splendid attire powder ration, sample storage box 11 adopts the screw thread to connect with sampler awl cylindric discharge gate.
Has the advantages that: the sampler is completely sealed, so that the leakage rate of the silicon powder is reduced; the push-pull type sampler is simple to operate, and labor intensity of workers is reduced; the sampler is in a sealing state when working, so that the materials are prevented from being sprayed out, and the danger in the sampling operation is reduced; after the sampler is applied, the problem that silicon powder is scattered during field sampling is successfully solved, and the annual cost can be saved by 10000 yuan.
The size of the material receiving box 9 is designed according to the sampling amount (100 g) of the finished powder, and the volume of the sample storage box 11 is larger than the size of the material receiving box 9, so that the material in the sampler is prevented from being stored after sampling. Under the non-working state of the sampler, the material receiving box is locked by the locking nut 6, and the sealing gasket 10 and the shell 4 form sealing to prevent silicon powder from entering the material receiving vessel in the operation process of the device.
The sampler loosens the locking nut 6 in a working state, pushes the push-pull rod 1 inwards, keeps the material receiving opening of the material receiving box 9 upwards for about 30s, pulls the push-pull rod 1 outwards, rotates the push-pull rod 1 clockwise, pours the sample in the material receiving box 9 into the sample storage box 11, screws down the sample storage box 11, and takes out the sample.
After this scheme is implemented, replaced traditional board-like sampler of turning over or the direct sample of quick-opening door, the application of totally enclosed plug-type sampler has reduced the leakage of material greatly, has reduced danger when the sample operation, has reduced worker's intensity of labour, has eliminated because of the influence of producing the material and leaking to environmental pollution.
