Description
Technical field
The utility model relates to a kind of silica flour and removes process equipment.
Background technology
Polycrystalline silicon material (the quick-fried particle of water) is in loading furnace process, because it contains silica flour, easily furnace inner environment is polluted, thus have influence on the quality of product, if silica flour adheres in single crystal growing furnace and circuit also easily causes single crystal growing furnace overcurrent, and then there is stewing stove accident.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of silica flour remove process equipment, it have cost of manufacture low, be convenient to install, be easy to the features such as operation.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Process equipment removed by a kind of silica flour, and comprise silica flour deduster, silica flour deduster comprises deduster bin, and deduster bin is isolated into filter cup and room two parts after filtering by medium effeciency filter, and filter cup is provided with air inlet, and after filter, room is provided with air outlet; Also comprise silica flour cast feeder, silica flour cast feeder comprises cast feeder bin, cast feeder bin top is provided with air outlet, and be provided with feeder screen in the middle part of it, its underpart is provided with air inlet, the outlet of infundibulate particle is provided with bottom it, the outlet of infundibulate particle is provided with seal cover, and feeder screen and the level and smooth accessory of cast feeder bin internal water connect, when feeder screen advances cast feeder bin, feeder screen outer end wall and cast feeder bin outer wall are sealed and matched, and also comprise blower fan; Above-mentioned silica flour deduster, silica flour cast feeder and blower fan form closed circulation ventilating system by pipeline connection.
The utility model improves further and is:
Blower fan is between silica flour deduster and cast feeder.
After the filter of silica flour deduster, room is communicated with air by air cleaner.
Cast feeder bin top is provided with pressure release butterfly valve.
The compass screen surface of the feeder screen of silica flour cast feeder is stainless steel mesh, is provided with tetrafluoro air conducting dividing plate in silica flour cast feeder, and tetrafluoro air conducting dividing plate is covered with the air conducting hole that diameter is 1.5mm-2.5mm.Tetrafluoro air conducting dividing plate periphery is connected with the cast feeder bin inwall between air inlet with feeder screen.
The beneficial effect adopting technique scheme to produce is:
The utility model passes through by equipment utilization driven by motor impeller, produce circulated air, utilize circulated air that silica flour in silica flour cast feeder is sucked silica flour deduster, filter through medium effeciency filter, silica flour is stopped by medium effeciency filter screen pack and stays deduster filter cup, thus reaches the effect of raw material without silica flour.After the filter of silica flour deduster, room is communicated with air by air cleaner, makes room and atmospheric pressure after the filter of silica flour deduster close, avoids the impact caused equipment because pressure reduction is too large; The compass screen surface of the feeder screen of silica flour cast feeder is stainless steel mesh, is provided with tetrafluoro air conducting dividing plate in silica flour cast feeder, and tetrafluoro air conducting dividing plate is covered with the air conducting hole that diameter is 1.5mm-2.5mm.Tetrafluoro air conducting dividing plate periphery is connected with the cast feeder bin inwall between air inlet with feeder screen, circulating air is made evenly to pass through feeder screen, improve dust removing effects, the silica flour of the utility model by containing in filtering polycrystalline silicon material, makes single crystal growing furnace charging pure, avoids the impact that the pollution because of silica flour causes product quality, and can avoid because silica flour causes the generation of short circuit phenomenon in single crystal growing furnace, thus avoid stewing stove accident, have cost of manufacture low, be convenient to install, be easy to the features such as operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In the accompanying drawings: 1, medium effeciency filter; 2, deduster filter cup; 3, blower fan; 4, pressure release butterfly valve; 5, feeder screen; 6, infundibulate particle outlet; 7, pipeline; 8, room after deduster filter; 9, air cleaner; 10, tetrafluoro air conducting dividing plate.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
Embodiment is as shown in Figure 1 known, the present embodiment comprises silica flour deduster, silica flour deduster comprises deduster bin, deduster bin is isolated into filter cup 2 and filter rear room 8 two parts by medium effeciency filter 1, filter cup 2 is provided with air inlet, after the filter of silica flour deduster, room 8 is communicated with air by air cleaner 9, and after filter, room 8 is provided with air outlet, also comprise silica flour cast feeder, silica flour cast feeder comprises cast feeder bin, cast feeder bin top is provided with air outlet, feeder screen 5 is provided with in the middle part of it, its underpart is provided with air inlet, infundibulate particle outlet 6 is provided with bottom it, infundibulate particle outlet 6 is provided with seal cover, feeder screen 5 and the level and smooth accessory of cast feeder bin internal water connect, when feeder screen 5 advances cast feeder bin, feeder screen 5 outer end wall and cast feeder bin outer wall are sealed and matched, the compass screen surface of the feeder screen 5 of silica flour cast feeder is stainless steel mesh, tetrafluoro air conducting dividing plate 10 is provided with in silica flour cast feeder, tetrafluoro air conducting dividing plate 10 is covered with the air conducting hole that diameter is 1.5mm-2.5mm.Tetrafluoro air conducting dividing plate 10 periphery is connected with the cast feeder bin inwall between air inlet with feeder screen 5, and cast feeder bin top is provided with pressure release butterfly valve 4; Also comprise blower fan 3; The air outlet of silica flour cast feeder is communicated with by pipeline 7 with the air inlet of silica flour cast feeder with the air outlet of air inlet silica flour deduster of silica flour deduster successively with the air outlet of the air inlet of blower fan, blower fan.
