Abstract
The utility model discloses a trichlorosilane sampling cabinet with a novel structure. The trichlorosilane sampling cabinet comprises a sampling bottle, wherein, a rubber plug is arranged on a bottle opening of the sampling bottle; and a needle head iss arranged on the rubber plug and connected with a hose communicated with a sampling valve. The trichlorosilane sampling cabinet with the structure has the advantages that sampling steps are simplified in a closed circuit environment, so that the sampling time is greatly shortened, the sampling bottle cannot be corroded in the sampling process, the authenticity of samples is guaranteed, and the requirements of safety and environmental protection can further be guaranteed.
Description
Technical field
The utility model belongs to the chlorosilane sampler in the production of polysilicon, relates to chlorosilane sampling cabinet device in pipeline and the equipment.
Background technology
Present existing trichlorosilane sampling cabinet, be designed to the closed cycle structure more, the sampling cabinet of this structure can reach safety and environmental protection requirement, but sampling process very loaded down with trivial details, consuming time especially (hour/sample), the sampling work efficiency is lower, and metal sampling steel cylinder is corroded by sample easily in the use, and contaminated samples causes the sample distortion.
Existing sampler structure, just like October 28 2009 applying date, the utility model patent of notification number CN201555740U discloses the online sampler of a kind of liquid chlorosilane, and described sampler comprises sampling jar, pipeline, T-valve, stop valve, sampling jar have an input port and a delivery outlet at least, that end of input port is connected with input media, and that end of delivery outlet is connected with output unit.The sampler of this structure, just more consuming time, and the situation of sample contamination appears easily.
So, in order to satisfy in now a lot of production runes to a large amount of demands of taking a sample of trichlorosilane, a lot of polysilicon producers also adopt the mode of sampling jar violence sampling to take a sample, shorten (only with 20 minutes) like this sample time greatly, but but brought the hidden danger of safety and environmental pollution, very easily caused the generation of accidents such as catching fire.
Summary of the invention
The purpose of this utility model is to offer a kind of trichlorosilane sampling cabinet of new construction, under closed circuit environment, simplify sampling procedure, not only shortened sample time greatly, and sampling jar can not corrode in the sampling process, guarantee the authenticity of sample, can also guarantee safety and environmental requirement.
The technical solution of the utility model is as follows:
Trichlorosilane sampling cabinet comprises sampling jar, and it is characterized in that: the bottleneck of described sampling jar is provided with rubber plug, and rubber plug is provided with syringe needle, and syringe needle is connected with the flexible pipe that is communicated with sample cock.
Described syringe needle is inserted logical rubber plug, sampling jar and soft pipe connection.
When needs are taken a sample, directly open sample cock, directly in sampling jar, import the trichlorosilane sample by flexible pipe, syringe needle.
The beneficial effects of the utility model are as follows:
The utility model adopts the structure of syringe needle and flexible pipe as sampling outlet, the sampling steel cylinder in the former design and the thread connecting mode of metallic conduit have been replaced, make the loading and unloading between sampler and the pipeline convenient, can finish in one, two minute, greatly shorten the sample time of each sample; Get final product if only need to change sampling jar plug syringe needle, can remove the process that sample is divided in sampling steel cylinder sampling back from same sampling spot continuous several times sampling;
The utility model adopts syringe needle to be connected the mode of sampling jar with rubber plug, forms closed environment, makes sample and site environment isolated, has stopped the injury of trichlorosilane sample to environment and personnel, reduces to the possibility of safety and the generation of environmental protection accident minimum;
The utility model and former sampling structure be relatively: have same airtight sampling environment, sample can exposed to air, and safety and environmental-protecting performance are fine; But the utility model loading and unloading are easier, sample time is shorter, efficient is higher;
The utility model only needs 20 minutes sample time; With existing sampling mode relatively, the closed environment that the utility model forms can guarantee that more sample can exposed to air, safety and environmental protection more reduced the safety of existing sampling mode and the accident potential of environmental protection.
