Abstract
The utility model relates to a leak-proof device used for auger delivery equipment. The leak-proof device comprises a guide chute (1) and an auger delivery shaft (2). The tail end of the guide chute is provided with a discharge port (3). A reverse hinge plate (4) is fixedly arranged on the auger delivery shaft and above the discharge port in the direction opposite to a delivered hinge plate. An ash baffle (5) is fixedly arranged on the tail portion of the auger delivery shaft. A slanting shaft hole (5-1) formed in the middle of the ash baffle is matched with the auger delivery shaft in shape. The bottom end of the ash baffle is arranged on the discharge port. The clearance between the slanting shaft hole and the auger delivery shaft is 0.3mm-0.5mm. The lower portion of the ash baffle (5) is provided with an ash guiding port (5-2). By means of the leak-proof device, the ash leakage problem of a shaft seal of a non-transmission end of the auger delivery equipment is solved, and environmental pollution and loss of products due to leakage are completely eradicated. In addition, the leak-proof device used for the auger delivery equipment is low in cost, convenient to install and obvious in effect.
Description
Technical field
The utility model relates to screw conveyor, specifically, refers to a kind ofly prevent material from leakage in the helical feed mode.
Background technology
Screw conveyor has simple in structure, and it is low to manufacture cost, advantages such as leak tightness is strong, easy-to-operate, but multiple spot loading, unloading material in centre is applicable to level or tilts conveying powdered, granular and little lump material.At present, screw conveyor is used very extensive at cement and granular material field, be widely used in departments such as chemical industry, building materials, metallurgy, grain, it is carried steadily, safeguards advantages such as simple, that fault rate is low, is subjected to users' favor deeply, but screw conveyor is when carrying cement or granular material, usually exist in non-driven end position and to carry the dead angle, buildup can't be removed, and can leak to the outside by axle and the gap of outer shaft when being accumulated to when a certain amount of buildup.After the friction of buildup and axial length time, there are certain wearing and tearing in output shaft simultaneously, form vicious circle with this.The material of revealing has not only caused pollution to environment, has also made enterprise's certain economic loss, and " race ", " emitting ", " leakage " phenomenon of solving screw conveyor become the technical barrier of being badly in need of solution.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of device for preventing leakage for screw conveyor, can remove the buildup of equipment non-transmision end.
The technical scheme that the utility model addresses the above problem is as follows:
A kind of device for preventing leakage for screw conveyor comprises deflector chute and screw conveyor shaft, it is characterized in that:
The end of described deflector chute offers discharging opening, is installed with the reverse hinge plate opposite with carrying hinge plate direction on the screw conveyor shaft of described discharging opening top.Oppositely the hinge plate can play good sealing and send grey effect.
As further improvement, the afterbody of described screw conveyor shaft is installed with ash damper, and the inclined shaft hole that described ash damper middle part is offered and the shape of screw conveyor shaft are complementary, and the bottom of ash damper is arranged on the discharging opening.This ash damper can will stop from the material that leaks between reverse hinge plate and the deflector chute, make material along the ash damper landing to discharging opening.
As preferably, the gap of described inclined shaft hole and screw conveyor shaft is 0.3mm-0.5mm.
Further again, the bottom of described ash damper offers leads the ash mouth.Because have little clearance between ash damper and conveying axis, a spot of material leaks to the ash damper inboard, when material accumulative total is a certain amount of, can leads the ash mouth by this and spill, be delivered to feed opening by reverse hinge plate equally.
As preferably, the described ash of leading mouthful is that length is that 50mm, width are the square hole of 30mm.
Principle of work of the present utility model is, at first by the effect of oppositely cutting with scissors plate most of mass transport is arrived feed opening, utilize ash damper to stop from the material that drops between reverse hinge plate and the deflector chute then, and landing is to oppositely cutting with scissors on the plate, oppositely the hinge plate rotates mass transport to the feed opening place by axle, simultaneously owing to have little clearance between ash damper and conveying axis, a spot of material leaks to the ash damper inboard, when material accumulative total is a certain amount of, can be spilt by the ash mouth of leading of ash damper, be delivered to feed opening by reverse hinge plate equally.
The beneficial effects of the utility model are:
By the enforcement of this device, solved the problem of spiral transfer device non-transmision end axle leak sealing ash, stopped the environmental pollution that produces because of leakage and the loss of product; In addition, the utility model cost is few, easy for installation, effect is obvious.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of middle ash damper of the present utility model.
Among the figure: 1, deflector chute; 2, screw conveyor shaft; 3, discharging opening; 4, oppositely cut with scissors plate; 5, ash damper; 5-1, inclined shaft hole; 5-2, lead the ash mouthful; 6, carry the hinge plate.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described in detail:
A kind of device for preventing leakage for screw conveyor comprises deflector chute 1 and screw conveyor shaft 2, it is characterized in that:
The end of described deflector chute offers discharging opening 3, is installed with the reverse hinge plate 4 opposite with carrying hinge plate 6 directions on the screw conveyor shaft of described discharging opening top.Oppositely the hinge plate can play good sealing and send grey effect.
The afterbody of described screw conveyor shaft is installed with ash damper 5, and the inclined shaft hole 5-1 that described ash damper middle part is offered and the shape of screw conveyor shaft are complementary, and the bottom of ash damper is arranged on the discharging opening.This ash damper can will stop from the material that leaks between reverse hinge plate and the deflector chute, make material along the ash damper landing to discharging opening.
As preferably, the gap of described inclined shaft hole and screw conveyor shaft is 0.3mm-0.5mm.
The bottom of described ash damper offers leads ash mouthful 5-2.Because have little clearance between ash damper and conveying axis, a spot of material leaks to the ash damper inboard, when material accumulative total is a certain amount of, can leads the ash mouth by this and spill, be delivered to feed opening by reverse hinge plate equally.
As preferably, the described ash of leading mouthful is that length is that 50mm, width are the square hole of 30mm.
Principle of work of the present utility model is, at first by the effect of oppositely cutting with scissors plate most of mass transport is arrived feed opening, utilize ash damper to stop from the material that drops between reverse hinge plate and the deflector chute then, and landing is to oppositely cutting with scissors on the plate, oppositely the hinge plate rotates mass transport to the feed opening place by axle, simultaneously owing to have little clearance between ash damper and conveying axis, a spot of material leaks to the ash damper inboard, when material accumulative total is a certain amount of, can be spilt by the ash mouth of leading of ash damper, be delivered to feed opening by reverse hinge plate equally.
