Detailed Description
To better illustrate the objects, aspects and advantages of the present invention, the present invention will be further described with reference to specific embodiments. The present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art, and the present invention will only be defined by the appended claims.
The chlorosilane filter is a device for filtering and separating crude chlorosilane products, or silicon powder particles in finished chlorosilane products, or other solid impurities to obtain purer chlorosilane products.
As shown in figures 1 and 2, the high-efficiency chlorosilane filter comprises a tank body 12 and a tank cover 9 connected to the tank body 12 through a quick-release flange, wherein a material outlet 4 is formed in the bottom of the tank body 12, and a material inlet 3 is formed above the side wall of the tank body 12. Crude chlorosilane enters the tank body 12 from the material inlet 3, and pure chlorosilane after filtration flows out from the material outlet 4. The material inlet 3 and the material outlet 4 are provided with valves.
An annular supporting plate 11 is fixedly mounted on the inner side wall of the tank body 12 below the material inlet 3, an upward opening supporting net 10 is sleeved above the annular supporting plate 11, an upward opening filter bag 8 is sleeved above the supporting net 10, an annular pressing sheet 7 is arranged above the filter bag 8, and the annular pressing sheet 7, the filter bag 8, the supporting net 10 and the annular supporting plate 11 are in locking connection through a plurality of bolts 6 which are radially and uniformly distributed.
The annular supporting plate 11 is a stainless supporting plate and is welded with the inner side wall of the tank body 12. The annular supporting plate 11 has strong bearing capacity, and the supporting net 10 and the filter bag 8 are sleeved above the annular supporting plate 11.
The filter bag 8 is made of polytetrafluoroethylene, and the precision of the filter bag 8 is 0.1-0.5 um. The filter bag 8 can filter large-particle silicon powder and impurities in crude chlorosilane products and fine silicon powder and impurities, the filtering efficiency is high, the purity of chlorosilane flowing out of the material outlet 4 is high, and the phenomenon of pipeline equipment blockage is not easy to occur.
The supporting net 10 is made of stainless steel materials, the supporting net 10 is cylindrical, the size of the supporting net 10 is the same as that of the filter bag 8, and the aperture of the supporting net 10 is larger than that of the filter bag 8. The support net 10 plays a role of supporting the filter bag 8, and prevents the filter bag 8 from dropping and breaking due to the fact that the filter bag 8 bears the overweight impurities in the filter bag 8.
The annular pressing sheet 7 is a stainless steel pressing sheet. The bolt 6 locks the annular pressing sheet 7 on the annular supporting plate 11, and the annular pressing sheet 7 is tightly attached to the annular supporting plate 11 to play a role in fixing the supporting net 10 and the filter bag 8. When the filter bag 8 needs to be replaced and cleaned, the filter bag 8 can be taken out by opening the bolt 6.
The annular supporting plate 11 and the annular pressing plate 7 of the supporting net 10 are preferably made of stainless steel of 316L material of EP grade.
Furthermore, the top of the tank cover 9 is provided with a nitrogen interface 2 and a pressure interface 1. The bottom of the tank body 12 is provided with a clean discharge port 5. The nitrogen interface 2 and the exhaust port 5 are provided with valves.
The working process is as follows: when the filter is used for filtering operation, the tank cover 9 and the tank body 12 are assembled together, the valves of the material inlet 3 and the material outlet 4 are opened, the valves of the nitrogen interface 2 and the drain port 5 are closed, and crude chlorosilane flows in from the material inlet 3, is filtered by the filter bag 8, flows out from the material outlet 4 and then flows into the storage tank and the rear working section.
When the filter is cleaned, valves of the material inlet 3 and the material outlet 4 are closed, valves of the nitrogen interface 2 and the exhaust port 5 are opened, nitrogen enters the tank body 12 from the nitrogen interface 2, residual chlorosilane in the tank body 12 is swept, and the nitrogen and the residual chlorosilane are discharged from the exhaust port 5. The lid 9 is then opened, the bolt 6 is opened, and the filter bag 8 and support mesh 10 are removed for cleaning.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
