Abstract
The utility model provides a ball-sealing air-locking discharging device. The ball-sealing air-locking discharging device comprises a rotating shaft (2), ball valve boxes (3) and a plurality of helical blades (1) fixed on the rotating shaft (1), ball valves are arranged in the ball valve boxes (3), a helical channel is formed between every two adjacent helical blades, and the ball valve boxes (3) are fixed between every two adjacent helical blades along the helical channels. The ball-sealing air-locking discharging device has the advantage that gravity of the ball valves (4) is utilized to realize periodic smoothness and blocking of the helical channels, tightness is improved, the number of the helical blades is reduced, the length of an integral device is shortened, manufacturing cost of equipment is lowered, and floor space is decreased.
Description
Technical field
The utility model relates to a kind of lock wind drawing mechanism, specifically, relates to a kind of ball sealing lock wind drawing mechanism, belongs to the cement machinery technical field.
Background technology
Existing lock wind drawing mechanism comprises following several: air locking valve with counter weight, multiple tracks gate, lattice wheel discharger and spiral lock wind.
Wherein, air locking valve with counter weight is mainly realized the keying of valve plate by the deadweight of material, during moment that the moment that turnover panel is produced when material produces turnover panel greater than weight, and the turnover panel upset, the beginning discharging, after discharging finished, under the Action of Gravity Field that weight produces, turnover panel was turned to original position, reach the purpose of lock wind discharge, air locking valve with counter weight is mainly used in static occasion, and temperature can not be too high, the poor reliability of equipment operation; The multiple tracks gate is to make gate open and close in certain sequence circulation endlessly, realizes the discharging of lock wind, and its shortcoming is complex structure, and cost is high, and cost of maintenance is high; Lattice wheels discharger is by the discharging of revolution lattice wheel, and airtight lock wind is to rely on runner plate and the two movable sealing pieces in both sides, and two sealing steel rings in two ends realize that its shortcoming is that accessory consumption is too fast, repairs frequently, and the backgauge scraper-trough conveyer gets stuck; Spiral lock wind is to guarantee that by the material envelope length that material forms material envelope length is longer, and leak tightness is better, but the relative number of helicallobe and the length of complete machine of also just having increased has increased device fabrication cost and floor area.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of ball sealing lock wind drawing mechanism is provided.
Ball sealing lock wind drawing mechanism of the present utility model, comprise rotating shaft (2), ball valve casing (3) and a plurality of helicallobe (1) that is fixed in the rotating shaft (2), be provided with ball valve (4) in the said ball valve casing (3), wherein form helical duct between two adjacent helicallobes, said ball valve casing (3) is fixed between two adjacent helicallobes along helical duct.
Said ball valve casing (3) top offers circular hole, and said circular hole top is fixed with steel plate, and said Circularhole diameter is greater than the diameter of ball valve (4); Said ball valve casing (3) is provided with the side plate perpendicular to helical duct, offers conical bore on the said side plate, and said conical bore diameter is less than ball valve (4) diameter; Said ball valve casing (3) inside is provided with guide plate.
Ball sealing lock wind drawing mechanism of the present utility model has following technique effect: utilize the gravity characteristic of ball valve (4) to realize the periodic unimpeded and obstruction of helical duct, improve leak tightness, reduce the helicallobe number, shorten complete machine length, reduce the device fabrication cost, reduce floor area.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is diagram of the present utility model.
Fig. 2 is that the A of Fig. 1 is to expansion drawing.
Wherein, 1 is helicallobe, and 2 are rotating shaft, and 3 is the ball valve casing, and 4 is ball valve.
The specific embodiment
As shown in Figure 1, 2, ball sealing lock wind drawing mechanism of the present utility model, comprise rotating shaft (2), ball valve casing (3) and a plurality of helicallobe (1) that is fixed in the rotating shaft (2), be provided with ball valve (4) in the said ball valve casing (3), wherein form helical duct between two adjacent helicallobes, said ball valve casing (3) is fixed between two adjacent helicallobes along helical duct.Said ball valve casing (3) top offers circular hole, and said circular hole top is fixed with steel plate, and said Circularhole diameter is greater than the diameter of ball valve (4); Said ball valve casing (3) is provided with the side plate perpendicular to helical duct, offers conical bore on the said side plate, and said conical bore diameter is less than ball valve (4) diameter; Said ball valve casing (3) inside is provided with guide plate.
The working process of ball sealing lock wind drawing mechanism of the present utility model is as follows: under the initial condition, because Action of Gravity Field, ball valve (4) is away from ball valve casing (3) side plate conical bore, and helical duct is unimpeded, and material can move forward along helical duct; After rotating shaft turned over 90 °, ball valve fell in the side plate conical bore along guide plate, stopped up helical duct, stoped gas to pass through; When rotating shaft turns over after 270 °, ball valve is got back to ball valve casing top again, and helical duct is unimpeded, and material can pass through smoothly; When rotating shaft turns over 360 °, get back to again initial condition, according to this circulation.Can axially stagger successively along rotating shaft during use arranges a plurality of ball sealing lock wind drawing mechanisms, realizes the staggered unimpeded and obstruction of many helical ducts, improves leak tightness.
Claims (2)
