Abstract
The utility model discloses a kind of atmospheric sampling to buffer drying tube, including drying tube, drying tube upper end are connected with air-out apparatus, drying tube lower end is connected with dashpot, upper and lower two mesh dividing plates are provided with drying tube, are provided with volute spring in dashpot, the side wall upper part of dashpot is provided with air inlet.The utility model atmospheric sampling buffers drying tube, the infundibulate that air-out apparatus is arranged to stand upside down, reduces air drag；By setting two mesh dividing plates in drying tube, blocking of the drier to gas circuit is effectively prevented；Dashpot is drier and air inlet separation, avoids the phenomenon that the pollution of solution suck-back causes drier to fail caused by operational error and occurs.
Description
Technical field
It the utility model is related to a kind of gas drying apparatus, and in particular to a kind of atmospheric sampling buffers drying tube.
Background technology
It is dried when being sampled to air or waste gas, the drying device of generally use is drying tube, existing
Drying tube air outlet parts are planar design, and air flow is not smooth, and resistance is larger；Drying tube body is fixed, versatility compared with
Difference, and drying tube air inlet is longer, adds air drag, and directly contacted with drier, drier easily blocks connection
Gas circuit, occurred using occurring the phenomenon that the pollution of solution suck-back causes drier to fail caused by operational error often.
Utility model content
The defects of existing for prior art, the purpose of this utility model are to provide a kind of atmospheric sampling buffering drying tube.
The utility model is the technical scheme adopted is that a kind of atmospheric sampling buffers drying tube, including drying tube, drying tube
Upper end is connected with air-out apparatus, and drying tube lower end is connected with dashpot, upper and lower two mesh dividing plates, dashpot are provided with drying tube
Interior to be provided with volute spring, the side wall upper part of dashpot is provided with air inlet.
Further, air-out apparatus is the infundibulate stood upside down.
Further, drying tube is connected through a screw thread with dashpot.
Further, the junction of drying tube and dashpot is provided with rubber ring.
Further, volute spring is gradually increased by lower from upper internal diameter, the internal diameter of volute spring upper inner diameter and drying tube
It is identical.
The beneficial effects of the utility model are the utility model atmospheric sampling buffering drying tube, air-out apparatus to be arranged to
The infundibulate of handstand, reduces air drag；By setting two mesh dividing plates in drying tube, effectively prevent drier to gas
The blocking on road；Dashpot is drier and air inlet separation, and avoiding the solution suck-back pollution caused by operational error causes drying
The phenomenon of agent failure occurs.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model atmospheric sampling buffering drying tube.
In figure, 1. air-out apparatus, 2. drying tubes, 3. dashpots, 4. mesh dividing plates, 5. volute springs, 6. air inlets.
Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of atmospheric sampling buffering drying tube of the utility model, as shown in figure 1, including drying tube 2, the upper end of drying tube 2 connects
Air-out apparatus 1 is connected to, the lower end of drying tube 2 is connected with dashpot 3, upper and lower two mesh dividing plates 4, two nets are provided with drying tube 2
The position of hole dividing plate 4 is movable, and silica-gel desiccant is housed between two mesh dividing plates 4, volute spring 5 is provided with dashpot 3, is delayed
The side wall upper part of jet-bedding 3 is provided with air inlet 6.
Further, air-out apparatus 1 is the infundibulate stood upside down.
Further, drying tube 2 is connected through a screw thread with dashpot 3.
Further, the junction of drying tube 2 and dashpot 3 is provided with rubber ring.
Further, volute spring 5 is gradually increased by lower from upper internal diameter, and the upper inner diameter of volute spring 5 is interior with drying tube 2
Footpath is identical.
In use, silica-gel desiccant is loaded onto between two mesh dividing plates 4 in drying tube 2 as needed first, then
Dashpot 3 is connected with drying tube 2, air enters dashpot 3 by air inlet 6, subsequently into passing through drying in drying tube 2
Afterwards, flowed out from air-out apparatus 1.
The utility model atmospheric sampling buffers drying tube compared with existing drying tube：
1st, current drying tube air outlet parts are planar design, and air flow is not smooth, and resistance is larger.Fallen in the utility model
Vertical funnel air-out apparatus 1 designs to be exported using airflow design, reduces air drag.
2nd, current drying tube body is fixed, and versatility is poor, and air inlet and gas outlet directly contact with drier,
Drier easily blocks connection gas circuit.Drying tube 2 is managed and uses mesh dividing plate 4 above and below interior in the utility model, effectively prevents drying
Blocking of the agent to gas circuit.Bottom connects volute spring 5, the flexibility of body is enhanced, in use, can fill as needed dry
The dosage of drying prescription.
3rd, current drying tube air inlet is longer, adds air drag, and is directly contacted with drier, using going out often
The phenomenon that now pollution of solution suck-back causes drier to fail caused by operational error occurs.Dashpot 3 sets in the utility model
Meter, makes drier be separated with air inlet 6, centre adds dashpot 3, efficiently solves problems.Air inlet design is dry
Below dry pipe, air inlet length is shortened, reduces resistance.
