Technical Field
The invention relates to an auxiliary mounting device and a plate penetrating joint component, in particular to an auxiliary mounting device and a plate penetrating joint component which can be accurately fixed, are not limited by space in mounting and have a simple and reliable structure as far as possible.
Background
Most samples collected during environmental air monitoring can hardly be directly analyzed without any pretreatment due to complex matrix composition or low concentration of target pollutants or enrichment on adsorbates, so that the samples need to be sent into an analysis instrument by matching different pretreatment technologies with different sampling technologies. The current common method is a low-temperature preconcentration-thermal desorption method, and the core equipment is a cold trap temperature control device. The low temperature can make the substance to be measured adsorb on the adsorbate, and the lower the temperature, the stronger the adsorbability, the temperature is controlled by the refrigeration system of the instrument itself. The heating can resolve the component to be detected on the adsorbate, the target substance flashes the volatile organic compound into the analytical instrument through a thermal desorption technology, the thermal desorption temperature is low, the component in the sample can be resolved incompletely, the thermal desorption temperature is too high, certain components in the sample can be decomposed, the recovery rate is low, even the adsorbate is damaged, and therefore a temperature controller is needed to monitor the temperature of the cold trap.
At present, a common refrigeration mode is refrigeration by using Peltier, a common heating mode is heating by a heating wire, a filling material is filled in a quartz tube, and the quartz tube is fixed in a cold trap cabinet, so that the quartz tube becomes a part of an air path. The cold trap machine box generates low-temperature refrigeration in a small range through the Peltier effect, and transmits the low temperature to the quartz tube, so that adsorbates in the quartz tube are in a low-temperature state, and a better adsorption effect is achieved. The flash evaporation method is to wind heating wires spirally around a quartz tube, and to instantaneously generate high temperature by the heating wires to analyze the component to be detected from the adsorbate.
The quartz capsule is located cold-trap quick-witted incasement, and the quartz capsule is the partly that belongs to in the gas circuit, need be connected quartz capsule and outside gas circuit, need connect at wearing plate of the curb plate installation of cold-trap quick-witted case this moment, among the wearing plate joint of prior art, connect on the curb plate and fix whole wearing plate joint through a fixation nut nestification on wearing plate joint, but because wearing plate joint's length is longer, produce great moment and make whole wearing plate joint's firm degree of installation form great influence to this fixation nut when wearing plate joint both ends plug gas pipeline. Therefore, when the pipes are inserted at the two ends of the plate penetrating joint in the prior art, the plate penetrating joint is easy to loosen, so that the cold trap case cannot work normally.
