Abstract

The utility model relates to an experimental facilities field, concretely relates to gas drying box is used in laboratory. The drying box comprises an air inlet pipe, an air outlet pipe, a front absorption chamber, a rear absorption chamber, a drying box body and a cover plate, wherein the air inlet pipe is communicated with the front absorption chamber, the rear absorption chamber is communicated with the air outlet pipe, a ventilating filter plate is arranged between the front absorption chamber and the rear absorption chamber, the cover plate can be tightly and tightly covered with the drying box body, and the cover plate and the drying box body are conveniently detached through a cover plate handle on the cover plate. After the gas flows through the front absorption chamber and the rear absorption chamber which are filled with different absorbents, various impurities can be removed to finish the purification of the gas. The utility model discloses simple structure, it is practical convenient, gaseous purification efficiency is high.

Description

Gas drying box for laboratory

Technical Field

The utility model relates to an experimental facilities field, concretely relates to gas drying box is used in laboratory.

Background

The gas is usually dried or some impurities in the gas are removed by using the drying tube in a chemical laboratory, the prior drying tube has small tube diameter and short length, the amount of a drying agent or an impurity removing reagent which can be contained is less, and the gas drying or impurity removing efficiency is lower in actual operation. In summary, how to improve the gas drying or impurity removal efficiency of the drying tube in the chemical experiment becomes a problem to be solved by those skilled in the art.

Disclosure of Invention

In view of the above shortcomings of the prior art, an object of the present invention is to provide a gas drying box for laboratory, which has a simple structure and is convenient to use.

In order to realize the above and other related objects, the utility model provides a gas drying box is used in laboratory, including intake pipe, outlet duct, preceding absorption chamber, back absorption chamber, dry box body and apron.

Preferably, the air inlet pipe is communicated with the front absorption chamber, the rear absorption chamber is communicated with the air outlet pipe, a clamping groove is arranged between the front absorption chamber and the rear absorption chamber, and a ventilation filter plate is arranged in the clamping groove.

Preferably, the drying box body and the cover plate can be tightly closed, and the cover plate is provided with a handle to facilitate the detachment of the drying box body and the cover plate.

Adopt the technical scheme provided by the utility model, compare with prior art, have following effect of showing: the drying box body comprises the front absorption chamber and the rear absorption chamber, the capacities of the two absorption chambers are larger than that of a traditional drying pipe, more solid drying agents or absorbents can be contained, and the moisture or impurities in the gas can be absorbed more fully; the clamping groove is arranged between the two absorption chambers, the ventilation filter plate can be fixed, different absorbents can be placed in the two absorption chambers respectively, the purpose of removing various impurities in the gas through one-time purification operation is achieved, and the comprehensive purification efficiency of the gas is improved; after the drying box body and the cover plate are tightly closed, gas flows into the front absorption chamber from the gas inlet pipe, flows into the rear absorption chamber through the ventilating filter plate, and finally flows out through the gas outlet pipe, so that the purification of the gas is completed. After the gas purification is finished, the handle on the cover plate is utilized to split the cover plate and the drying box body, so that the absorbent can be cleaned and recovered, and the drying box body can be cleaned and recovered.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. the air inlet pipe, 2, the air outlet pipe, 3, the front absorption chamber, 4, the rear absorption chamber, 5, the cover plate, 6, the cover plate handle, 7, the ventilation filter plate, 8, the clamping groove, 9 and the drying box body.

Detailed Description

In order to explain the present invention more clearly, the present invention will be further described with reference to the preferred embodiments and the accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.

As shown in fig. 1, use the utility model discloses the time, earlier with the filter plate 7 card of ventilating in draw-in groove 8, then according to the order of detaching impurity in the gas, in the preceding absorption chamber 3 of packing into respectively with the solid absorbent that corresponds or drier, with apron 5 and the tight back of dry box body 9 lid, gas lets in from intake pipe 1, and gas flows through preceding absorption chamber 3 through the filter plate 7 of ventilating before, and the back absorption chamber 4 of flowing through again flows through, flows out from outlet duct 2 at last, accomplishes gaseous purification. After the experiment, utilize apron handle 6 to unpack apart apron 5 from dry box body 9, can be to the absorbent clear up and to the washing and the recovery of dry box body 9.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.

Claims

1. The utility model provides a laboratory is with gaseous drying box, its characterized in that includes intake pipe, outlet duct, preceding absorption chamber, back absorption chamber, dry box body and apron, the intake pipe with preceding absorption chamber communicates with each other, back absorption chamber with the outlet duct communicates with each other, preceding absorption chamber with there is the filter plate of ventilating between the back absorption chamber, the apron can with dry box body lid is airtight, the apron handle on the apron is convenient for with the apron with dry box body split.
