The utility model has simple structure, and the utility model has the functions of automatic sealing and dust prevention for two times. The utility model can be widely used for dust discharging and material discharging for various dust-discharging devices and dust material barns.

Description

Self-closing screw type cinder dischanging device

The utility model relates to a kind of equipment that is used for environmental protection dust exhaustor and dust feed bin ash discharge discharge, and is particularly a kind of from close spiral dust unloadnig apparatus.

The dust that the present dusting equipment that is used for environmental protection in industrial enterprise preserves after dedusting all is at ash hole place installing star-shaped ash unloading valve or adopts flap valve control ash discharge, the unloading valve of these two kinds of forms all has gas leakage, because of all there is certain negative pressure at the cinder-discharging port place, cause reentrainment of dust, and work as amount of dust for a long time, under the compression weight of material, sometimes make above-mentioned two kinds of unloading valves stuck phenomenon occur easily, discharging opening at the dust feed bin generally also is the above-mentioned two kinds of unloading valves of installing, have gas leakage equally, stuck and the shortcoming of dust for the second time causes the halfway phenomenon of environmental pollution or environment protection treating.

The purpose of this utility model be to provide a kind of can overcome occur when unloading ash stuck phenomenon and voluntarily leak free from close spiral dust unloadnig apparatus.

The utility model is finished with following mode: it comprises motor 1 and hopper 2, delivery pipe 3 vertically is equipped with in lower end at hopper 2, transmission shaft 4 is housed in delivery pipe 3, helicallobe 5 is housed on transmission shaft 4, one end of transmission shaft 4 pass sealing arrangement 6 be connected in motor 1 the axle on, rear side housing 7 is housed on the other end of delivery pipe 3, shrimp shape ash-unloading tube 8 is housed on rear side housing 7, flexible pipe 9 is housed in the lower end of ash-unloading tube 8.Sealing arrangement 6 is to connect the sleeve pipe 10 of an internal diameter greater than delivery pipe 3 internal diameters by the end at delivery pipe 3, front end cover 11 in the end of sleeve pipe 10, fix with the flange that bolt 12 connects on front end cover 11 and the delivery pipe 3, bearing seat 13 and bearing 14 are housed in sleeve pipe 10, front end at bearing seat 13 has labyrinth dust ring 15 to be contained on the transmission shaft 4, transmission shaft 4 pass bearing seat 13 and bearing 14 and front end cover 11 be connected in motor 1 the axle on.Labyrinth dust ring 15 is to realize that by groove circle and protruding circle male and female cooperates with contact surface between the bearing seat 13.

The utility model is from close spiral dust unloadnig apparatus, owing to adopt helicallobe to push particulate dust, what of weight of material in the feed bin can be not stuck with it, it is to be connected on the ash hole of various dust exhaustors and dust feed bin, by helicallobe the material dust is pushed to shrimp shape cement output tank, at shrimp shape ash-unloading tube mouth dustproof flexible pipe being housed delivers to the dust storehouse to dust or transports with special vehicle, dustproof flexible pipe not only can prevent outside the airborne dust second time when carrying dust, and can be when this machine quits work, after the first road helicallobe seals voluntarily, because the suction function of dust exhaustor, cause dustproof flexible pipe to be adsorbed on the shrimp shape mouth of pipe, play for the second time sealing function voluntarily, it improves widely and has overcome existing star-shaped ash unloading valve, the gas leakage that the turnover panel unloading valve exists, stuck and the shortcoming of dust for the second time.It can be widely used in the usefulness of various dust exhaustors and various dust feed bin ash discharge discharges.

Fig. 1 is the utility model structural representation

Below in conjunction with accompanying drawing the utility model is described in further detail:

As shown in Figure 1, from close spiral dust unloadnig apparatus is to install hopper 2 by the ash hole place at feed bin, hopper 2 adopts laddertron, in the lower end of hopper 2 delivery pipe 3 is housed vertically, and the axis normal of delivery pipe 3 is in the axis of hopper 2, delivery pipe 3 adopts solid drawn pipe, hopper 2 is communicated with delivery pipe 3, in the rear end of delivery pipe 3 rear side housing 7 is housed, and shrimp shape ash-unloading tube 8 is housed on rear side housing 7, ash-unloading tube 8 is communicated with delivery pipe 3, and dustproof flexible pipe 9 is housed in the lower end of shrimp shape ash-unloading tube 8.Front end at delivery pipe 3 is equipped with sealing arrangement 6, sealing arrangement 6 is to connect the sleeve pipe 10 of an internal diameter greater than delivery pipe 3 internal diameters by the end at delivery pipe 3, bearing seat 13 is housed in sleeve pipe 10 leans end at delivery pipe 3, be pressed against on the bearing seat 13 with front end cover 11 then, with the flange on bolt 12 connection front end covers 11 and delivery pipe 3 ends, make front end cover 11 fixing, bearing 14 is housed in bearing seat 13, after transmission shaft 4 passes bearing seat 13 and bearing 14 and front end cover 11, be sleeved on the axle of motor 1, fix with key.Packing ring is housed front end on transmission shaft 4 and nut leans bearing 14; make bearing 14 location transmission shafts 4 and front end cover 11 and and bearing seat 13 between all have wool felt to enclose sealing function; on transmission shaft 4, labyrinth dust ring 15 is housed and leans front end at bearing seat 13 with nut and stop pin; as shown in Figure 1; there are multi-turn groove and protruding circle to realize that male and female cooperates on the contact surface of labyrinth dust ring 15 and bearing seat 13; play antisoiling effect; the permanent use of protection bearing 14; helicallobe 4 is arranged on transmission shaft 4; work to advance the dust reach of getting off in the feed bin; transmission shaft 4 is hollow tubulars; in its end one door is arranged; the sealing of this machine is by the delivery pipe of screw machine; preserving dust in receiving opening voluntarily plays from close effect as charges; if after the dust that preserves in this machine is all unsnatched; also just inhale stifled sealing voluntarily by the flexible pipe at shrimp shape mouth of pipe place; because this machine is mounted in the cinder-discharging port position of dust exhaustor bottom; all there is negative pressure to a certain degree at general dust exhaustor cinder-discharging port place; just be close to cinder-discharging port, just can obtain leak free effect voluntarily by the negative-pressure adsorption flexible pipe of dust exhaustor self.
