Abstract
The utility model discloses a screw conveyer for ultrafine nano calcium carbonate powder, and solves the technical problem that a high-quality shaft seal is replaced frequently for the conventional screw conveyer for the ultrafine nano calcium carbonate powder. The screw conveyer for the ultrafine nano calcium carbonate powder comprises a material outlet (8) formed in a screw conveyer casing (1), an end part blocking box (4) is arranged at the left side end, close to the material outlet (8), of the screw conveyer casing (1), a bearing (6) is arranged on the end part blocking box (4), the left end of a center shaft (7) of the screw conveyer is arranged in the bearing (6), screw conveying rotary vanes (2) are arranged on the center shaft (7) of the screw conveyer, a polytetrafluoroethylene seal cartridge (5) is arranged between the end part blocking box (4) and the left end of the screw conveyer casing (1), and screw conveying rotary vanes (3) which are mounted in reverse direction are arranged on the center shaft (7) between the material outlet (8) and the left end of the screw conveyer casing (1). According to the screw conveyer for the ultrafine nano calcium carbonate powder, the maintenance frequency of the equipment bearing is reduced.
Description
Technical field
The utility model relates to a kind of powder conveyor screw, particularly a kind of nano-calcium carbonate superfine powder conveyor screw.
Background technology
Conveyor screw is the main feedway of the one of powder conveying, in actual use, due to the ultra-fine performance of superfine powder, more easily enter the inside of the common shaft seal of conveyor screw, due to the lipophilic of its powder, powder just becomes a kind of hard material after contacting with lubricating oil, directly cause bearing locking to be burnt.Although existing, existing nano-calcium carbonate superfine powder conveyor screw frequently changes high quality shaft seal, but still cannot solve nano-calcium carbonate, enter bearing inside, cause the problem of breakdown of equipment, the maintenance workload of equipment is large, has had influence on the stability of carrying the delivery system of nano-calcium carbonate superfine powder.
Summary of the invention
The utility model provides a kind of nano-calcium carbonate superfine powder conveyor screw, has solved the high technical matters of equipment failure rate that existing nano-calcium carbonate superfine powder conveyor screw exists.
The utility model is to solve by the following technical programs above technical matters:
A kind of nano-calcium carbonate superfine powder conveyor screw, comprise screw conveyor housing, on screw conveyor housing, be provided with material outlet, left-hand end at the screw conveyor housing near material outlet is provided with plug at end part box, on plug at end part box, be provided with bearing, the left end of the center shaft of conveyor screw is arranged in bearing, on the center shaft of conveyor screw, be provided with helical feed blade, between plug at end part box and the left-hand end of screw conveyor housing, be provided with polytetrafluoro sealing shroud, on the center shaft between material outlet and the left-hand end of screw conveyor housing, be provided with the helical feed blade that reversing sense is installed.
The helical feed blade that reversing sense is installed is arranged on apart from the center shaft at the left-hand end 100-200 millimeter place of screw conveyor housing.
The beneficial effects of the utility model are, have guaranteed that the normal erect type spin of superfine powder is carried, and have extended the bearing service life on conveyor screw, have reduced the maintenance frequency of equipment bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated:
A kind of nano-calcium carbonate superfine powder conveyor screw, comprise screw conveyor housing 1, on screw conveyor housing 1, be provided with material outlet 8, left-hand end at the screw conveyor housing 1 near material outlet 8 is provided with plug at end part box 4, on plug at end part box 4, be provided with bearing 6, the left end of the center shaft 7 of conveyor screw is arranged in bearing 6, on the center shaft 7 of conveyor screw, be provided with helical feed blade 2, between plug at end part box 4 and the left-hand end of screw conveyor housing 1, be provided with polytetrafluoro sealing shroud 5, on the center shaft 7 between material outlet 8 and the left-hand end of screw conveyor housing 1, be provided with the helical feed blade 3 that reversing sense is installed.
The helical feed blade 3 that reversing sense is installed is on being arranged on apart from 100 millimeters of the left-hand end of screw conveyor housing 1 to the center shaft 7 at 200 millimeters of places.
The utility model be known screw conveyor shaft approach the about 200-300 millimeter of tail bearing place, the namely feed opening place of spiral material, all anti-dresses of original helical feed blade, makes material no longer to bearing direction, continue extruding to feed opening place.And lengthened center shaft 7, polytetrafluoro sealing shroud 5 has been installed to be sealed, superfine powder is to material feed opening place, due to the effect of the anti-helical feed blade filling, powder is no longer to the extruding of bearing place, and the powder that sub-fraction was pushed is blocked by polytetrafluoro sealing shroud 5, to polytetrafluoro sealing shroud, can not produce chemical combination coagulation, thereby bearing has been avoided and the contacting of the superfine powder of high concentration, and has guaranteed its normal service life.
