Sealing；
Spool is located at the guide duct lower portion, is close to the transparency window side setting, both ends are rotationally connected with institute
State transparency window madial wall, blocked sewage front edge of board is connect with the spool, and the spool can be followed to rotate, expand into plate and with institute
The connection of transparency window madial wall is stated to fix or pack up as web-like；The pollutant baffle plate is made of soft and with gas permeability material.
Further, the pollutant baffle plate end sets clamping joint and spool magnetic stripe, and the transparency window madial wall accordingly sets clamping
Mouthful and fixed magnetic stripe, the card interface and the fixed magnetic stripe when the pollutant baffle plate expands into plate, respectively with the clamping
Head engages and is attracted with the spool magnetic stripe, with the fixation pollutant baffle plate.
Further, the pollutant baffle plate is made of non-woven fabrics.
Further, the transparency window madial wall setting is close at each edge of guide duct lower bottom end.
The utility model provides a kind of draught cupboard with blocked sewage structure, has the advantages that：
The 1st, blocked sewage structure below guide duct is set, can effectively block dirt, keeps draught cupboard clean, while be avoided that logical
Wind cupboard corrosion product falls into laboratory sample, improves the accuracy of experimental result；
2nd, the pollutant baffle plate in blocked sewage structure convenient for cleaning and is replaced, easy to maintain, and maintenance cost is low；
3rd, blocked sewage structure tool is unfolded and rolls two kinds of forms, rolls blocked sewage structure without using during blocked sewage structure, maximum journey
Degree keeps the air quantity of draught cupboard, can effectively reduce the corrosion of acid-base pair draught cupboard hot in heating process；
4th, effectively extend the service life of draught cupboard, reduce the financial cost for replacing draught cupboard.

Specific embodiment
Purpose, technical scheme and advantage to make the utility model embodiment are clearer, new below in conjunction with this practicality
Type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described implementation
Example is the utility model part of the embodiment, instead of all the embodiments.Based on the embodiment in the utility model, this field
Those of ordinary skill's all other embodiments obtained without creative efforts, belong to the utility model
The range of protection.
As shown in FIG. 1 to 3, structural relation is：Draught cupboard includes sequentially connected cupboard bottom 11, transparency window from the bottom to top
12 and cupboard top 13,13 top of cupboard top sets gas port, and guide duct top 21 passes through gas port setting, and guide duct lower part 22 is communicated in guide duct
21 bottom end of top, 21 outside of guide duct top are sealed with gas port；
Spool 31 is located at 22 lower section of guide duct lower part, and the setting of 12 side of close-fitting transparent window, both ends are rotationally connected with transparent
