Description
Technical field
This utility model relates to a kind of sealing structure, particularly in the sealing structure used on liquid silicon tetrachloride filter。
Background technology
It is that the pyrohydrolysis that burns in combustion furnace generates silicon dioxide by after the hydrogen of about 90 DEG C, air and the mixing of Silicon chloride. gas that vapor phase method produces silicon dioxide, then through aggregator aggregates, gas solid separation, deacidification dehydration, becomes product through vacuum packaging after。Liquid silicon tetrachloride is the by-product after silica flour separates with rectification after hydrogen chloride gas gas-solid reaction。Liquid silicon tetrachloride still contains minute quantity silica flour and silicon dioxide。Generally, remove the pretreating process of liquid silicon tetrachloride impurity for filtering and rectification, but rectification is relatively costly。Therefore, filtration is adopted to carry out removal of contamination under meeting material content situation up to standard。
Current liquid silicon tetrachloride filter is mainly rustless steel basket filter and y-type filter, and its filter material is all the stainless steel filtering net being lined with punching corrosion resistant plate。The hydrolysis during moisture in air is run into very fierce due to Silicon chloride., rustless steel filter material and the sealing member of filter are produced serious corrosion by the hydrochloric acid produced, dregs are easily from the sealing leakage corroded, therefore, repeatedly can be substantially reduced filter seal effect after cleaning impurity, not only affect filter capacity, also can bring safety problem because of leakage。How to design the sealing structure on liquid silicon tetrachloride filter, be the key point being related to liquid silicon tetrachloride filter service life and filter capacity。
Summary of the invention
The purpose of this utility model seeks to provide a kind of liquid silicon tetrachloride filter seal structure, improves filter service life and the efficiency of cleaning impurity。
In order to achieve the above object, the liquid silicon tetrachloride filter seal structure that this utility model provides has discharge nozzle, feed pipe, filter casing wall, upper flange plate, lower flange, screw thread, step ladder circular ring pipe, filter bag, rustless steel anchor ear, wherein, described upper flange plate is connected to feed pipe Basolateral, described lower flange is connected to outside filter casing wall upper end, and upper flange plate and lower flange are threaded connection；Discharge nozzle is fixed on filter casing wall upper outside；Described step ladder circular ring pipe has top cover, body, spill annular groove, and described top cover is fixed between upper flange plate and lower flange, and top cap central has a hole to communicate with feed pipe；Described body is fixed on top cover lower end, has a spill annular groove outside body；The upper end bag mouth of described filter bag is placed in spill annular groove, and the upper end bag mouth of filter bag is fixed in spill annular groove by described rustless steel anchor ear。
For making this utility model be suitable to application further, filter bag is PTFE overlay film material manufacture。
When this utility model uses, first the upper end bag mouth of filter bag is placed in spill annular groove, with rustless steel anchor ear, the upper end bag mouth of filter bag is fixed in spill annular groove, filter bag is put into filter cylinder again, being placed between upper flange plate and lower flange by top cover, top cover is fixed between upper flange plate and lower flange by fastening screw thread；During cleaning impurity, unclamp screw thread and step ladder circular ring pipe can be taken out in the lump together with filter bag in filter cylinder。
The liquid silicon tetrachloride filter seal structure that this utility model provides has positive effect: the upper end bag mouth of filter bag is fixed in spill annular groove by rustless steel anchor ear, top cover is fixed between upper flange plate and lower flange, does not result in leaking in sealing place of liquid silicon tetrachloride；Rustless steel anchor ear is consumable accessory, changes easily；Unclamp screw thread during cleaning impurity can be taken out in filter cylinder in the lump together with filter bag by step ladder circular ring pipe, convenient and swift。
Accompanying drawing explanation
This utility model will be further described in conjunction with accompanying drawing, refer to accompanying drawing:
Accompanying drawing 1 represents schematic diagram of the present utility model。
Structure shown in accompanying drawing 1 includes: feed pipe 1, upper flange plate 2, top cover 3, screw thread 4, spill annular groove 5, lower flange 6, rustless steel anchor ear 7, discharge nozzle 8, body 9, filter bag 10, filter casing wall 11。
