Description
Technical Field
The utility model relates to a sampler for powdery or granular solids, and relates to the field of sampling.
Background
The powdery solids have different compositions and different properties. But all have the risk of explosion in a confined space. Traditional sampling brings harm to the health of personnel, and can also cause the pollution to the environment simultaneously. When sampling is carried out in a negative pressure environment, the pressure of a process pipeline is easy to be unbalanced, and further production accidents are caused.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a sampler for powdery or granular solids, and the technical scheme of the sampler is as follows:
the utility model provides a sample thief for likepowder or granular solid, is including sampling main part, nitrogen gas intake pipe, nitrogen gas stop valve, nitrogen gas check valve, unloading stop valve, medium check valve and unloading pipeline one side of sampling main part is provided with the medium entry, and the bottom of this sampling main part is provided with the thief hatch of being connected with the sampling container, installs unloading stop valve, medium check valve and unloading pipeline on the ejection of compact pipeline at this sampling main part top in proper order, with be provided with the admission line in the corresponding sampling main part of medium entry, install nitrogen gas check valve, nitrogen gas stop valve and nitrogen gas intake pipe on this admission line in proper order the sampling main part in still install and filter water conservancy diversion mechanism.
The filtering and flow guiding mechanism comprises a filter screen, an annular pipe and an air injection hole, the upper part in the sampling main body is provided with the filter screen, the lower part of the filter screen is provided with the annular pipe, a space is formed between the annular pipe and the filter screen, the annular pipe is close to the medium inlet, and the air inlet end of the annular pipe is communicated with the air inlet pipeline; and a plurality of gas injection holes are arranged on the inner side surface of the annular pipe along the circumferential direction of the annular pipe, and face the medium inlet.
The air injection holes are arranged in a conical shape.
The utility model has the advantages that:
(1) the nitrogen blowback enables solid powder or particles to be collected and the inner wall of the sampling main body to be cleaned more smoothly.
(3) The efficiency of collecting the powder improves, and the setting of filter screen has prevented the escape of dust simultaneously.

Detailed Description
The utility model will be further described with reference to specific embodiments, and the advantages and features of the utility model will become apparent as the description proceeds. These examples are illustrative only and do not limit the scope of the present invention in any way. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model, and that such changes and modifications may be made without departing from the spirit and scope of the utility model.
Referring to fig. 1 to 3, the utility model relates to a sampler for powdery or granular solids, which comprises a sampling main body 1, a nitrogen inlet pipe 4, a nitrogen stop valve 6, a nitrogen check valve 12, a vent stop valve 7, a medium check valve 8 and a vent pipe 5, wherein one side of the sampling main body 1 is provided with a medium inlet 2, the bottom of the sampling main body 1 is provided with a sampling port 3 connected with a sampling container, a discharge pipe at the top of the sampling main body 1 is sequentially provided with the vent stop valve 7, the medium check valve 8 and the vent pipe 5, the sampling main body 1 corresponding to the medium inlet 2 is provided with an inlet pipe, the inlet pipe is sequentially provided with the nitrogen check valve 12, the nitrogen stop valve 6 and the nitrogen inlet pipe 4, and the sampling main body 1 is internally provided with a filtering and flow guiding mechanism.
The filtering and flow guiding mechanism comprises a filter screen 9, an annular pipe 10 and an air injection hole 11, wherein the filter screen 9 is arranged at the upper part in the sampling main body 1, the annular pipe 10 is arranged at the lower part of the filter screen 9, a space is formed between the annular pipe 10 and the annular pipe 10, the annular pipe 10 is close to the medium inlet 2, and the air inlet end of the annular pipe 10 is communicated with the air inlet pipeline; the inner side surface of the annular tube 10 is provided with a plurality of gas injection holes 11 along the circumferential direction of the annular tube 10 (the gas injection holes 11 are arranged in a conical shape), the gas injection holes 11 face the medium inlet 2, and the conical gas injection holes are more favorable for the dispersion of materials.
The working principle of the utility model is as follows:
a sampling container is connected to the sampling port 3, and after materials (powder or solid particles) to be sampled enter the sampling main body through the medium inlet 2, the medium inlet is closed; the emptying stop valve 7 and the nitrogen stop valve 6 are opened, and materials are uniformly blown away under the action of nitrogen after entering the sampling main body, so that the sampling efficiency is rapidly improved; meanwhile, the materials which are not collected are filtered by the filter screen 9 and then discharged to a discharge pipeline; and after sampling is finished, the sampling container is detached, and sampling is finished.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
