The interior of the spiral air locking valve body is full of powder material, and the quantitive material in the spiral air locking valve body and the aggregate bin functions as main air locking medium, thereby ensuring good air locking performance and sealing effect.
Description
Technical field
The utility model relates to dry powder shape material discharging lock wind technology, particularly a kind of dryer screw unloading air valve.
Background technology
As everyone knows, through behind the drying machine drying, the dry powder shape material in the aggregate bin requires its underpart air valve guaranteeing to prevent the generation of air leakage phenomena effectively under the unobstructed prerequisite of discharging when discharging.The unpowered devices such as weight flap valve, duplex flap valve, check apron that mostly are that use in this occasion are locked wind at present.These devices are owing to just exist the defective that can't overcome in design itself, so can't eliminate the generation of discountinuity air leakage phenomena, out of reach is locked the requirement of wind fully.
The weight flap valve is to utilize the deadweight of material and the balance between the weight to realize lock wind, and its shortcoming is:
(1), common weight flap valve rolls by steel plate and forms, the gap between turnover panel and the discharge tube is bigger, false air coefficient is bigger, causes locking the wind poor effect.
(2), use certain hour after because moisture capacity, variation of temperature cause the valve plate distortion, increasings that cause leaking out, it is not good enough to lock the wind effect.
(3), in the material as contain graininess and very easily between turnover panel and discharge tube, form stuckly, cause normally discharging, cause the system-down processing.
The duplex flap valve is to be in series by two weight flap valves, the theory wind effect of locking is better than weight flap valve, but it self shortcoming does not change, increased the coordinated balance problem between the two pass simultaneously, very easily cause down logical stifled or the upward logical stifled down or two adverse consequencess of opening that, cause normally discharging, lock wind.
Check apron is to be placed in the bevelled discharge pipe by flexible material.Its shortcoming be material in continuous discharge, also formed the passage that leaks out, cause locking wind effect extreme difference; Otherwise check apron and discharge pipe gap are too little, and it is not smooth easily to form discharging.
The utility model content
Technical problem to be solved in the utility model is, at the deficiencies in the prior art part, provides a kind of spiral air valve, is guaranteeing to be in good lock wind state when dry powder shape material can smooth and easyly in time draw off.
The technical scheme in the invention for solving the technical problem: comprise aggregate bin, last level-sensing device, control system, following level-sensing device, bolt, spiral air valve body, helicallobe, electric brake plate valve, center shaft.
Aggregate bin becomes an integral body with spiral air valve body and function Bolt Connection, and spiral air valve body is cylindrical.
Last level-sensing device and following level-sensing device are installed on the aggregate bin.
The bottom of spiral air valve body is provided with the electric brake plate valve, is connected on the control system with last level-sensing device, following level-sensing device.Control system will go up signal reaction that level-sensing device and following level-sensing device transmit to the electric brake plate valve.
Helicallobe is fixed on the center shaft and forms an integral body and place the centre of spiral air valve body and weld with spiral air valve body.The lead angle of helicallobe is α, greater than the natural angle of repose (a kind of physical property that material self is had) of material.
During work, when material is heaped the position that highly arrives level-sensing device in aggregate bin, last level-sensing device in time passes to control system with signal, and control system will go up signal reaction that level-sensing device transmits to the electric brake plate valve, and the electric brake plate valve can the discharging of self-opening sluice gate.When material arrives cylindrical spiral air valve body,, guarantee that material can be naturally swimmingly by round screw thread air valve body because the lead angle of helicallobe is the natural angle of repose (a kind of physical property that material self is had) of α greater than material.After discharging a period of time, when the material level of material dropped to the bottom level-sensing device, following level-sensing device also in time passed to control system with signal, and control system will descend signal reaction that level-sensing device transmits to the electric brake plate valve, electric brake plate valve meeting SELF CL sluice gate stops discharging.
The material stock amount in the collecting bin that so just makes is between level-sensing device and the following level-sensing device all the time, keeps dynamical equilibrium always.Aggregate bin, spiral air valve body, helicallobe, gate valve, center shaft and aggregate bin and the endoceliac granular material of spiral locking-valve are formed a sealed body together, in spiral air valve body inside, granular material also is in full state always, and the quantitative material in aggregate bin and the spiral air valve body is guaranteed good lock wind performance and sealing effectiveness as lock wind medium main body.
The beneficial effects of the utility model are:
1, lock wind performance is good: owing to utilize the quantitative powdery in body cavity and the aggregate bin to heap material as sealing medium, guaranteed the lock wind effect of system.
2, system performance is stable: the sealing effectiveness that does not influence system because of factors such as component wears.
3, comformability is stronger: strong to different material powdery comformability, it is applicable to the different discharging places that require such as malleation, negative pressure simultaneously.
4, microkinetic or unpowered discharging: this device utilizes the discharging voluntarily of material self gravitation, consumption of power few (automatic guidance) or non-power consumption (manually).
5, this device low cost of manufacture, fabrication and installation are convenient.
