Abstract
The utility model discloses a device for preventing flying dust of material down flow pipe. The utility model comprises a material down flow pipe (1). A connection pipe (5) that is connected with cavity of the material down flow pipe (1) is near feed port (2) on material down flow pipe (1), and lower port of the connection pipe (5) is arranged near discharge port (3) of material down flow pipe (1). The utility model not only has advantages of reducing air quantity from entrance of the down flow pipe, decreasing pressure on material drop point and reducing flying dust effectively, but also has advantages of simple structure, good dustproof effect and convenient operation. Using the utility model can improve working environment and protecting body health of workers effectively.
Description
Technical field:
The utility model relates to a kind of device that prevents dust emission from lay-off elephant trunk, belongs to the emission of baiting chute technical field of convey materials.
Background technology:
At present, in the process of using the elephant trunk convey materials, the air admission emission of baiting chute when material enters emission of baiting chute by inlet point in the meeting inducing peripheral environment, because air is mobile, the pressure of emission of baiting chute inlet point position is less than ambient pressure; And at the discharging opening of emission of baiting chute, because its aerodynamic energy changes potential energy into, the pressure of this position is greater than ambient pressure, like this, under the effect of big pressure, will produce a large amount of airborne dusts in company with the air that contains dust that material comes out together by the emission of baiting chute discharging opening at the discharging point place, thereby environment is polluted, and harm laborer's is healthy.So the emission of baiting chute of existing convey materials in use, and its result of use still is not ideal enough.
Summary of the invention:
The purpose of this utility model is: provide a kind of effect device that prevents dust emission from lay-off elephant trunk better, easy to use simple in structure, dustproof, to overcome the deficiency of existing emission of baiting chute.
The utility model is achieved in that it comprises emission of baiting chute 1, on emission of baiting chute 1, be connected with a communicating pipe 5 that communicates with the inner chamber of emission of baiting chute 1, and the lower port of communicating pipe 5 is arranged on discharging opening 3 places near emission of baiting chute 1 near its inlet point 2 places.
On the lower port of communicating pipe 5, be connected with a reducing pipe 4.
Below the discharging opening 3 of emission of baiting chute 1, also be provided with a deflector chute 6 that can be arranged on the conveyer 8, and a dust collection cover 7 also is housed on deflector chute 6.
Owing to adopted technique scheme, when passing through emission of baiting chute of the present utility model to convey materials such as rubber conveyors, material enters in the body by its inlet point, the higher dusty gas of its discharging opening position pressure by the collection of reducing pipe after under the pressure differential effect by entering the lower position of elephant trunk inlet point pressure communicating pipe, thereby reduced the impact that dusty gas and discharging point produced, and reduced the elephant trunk inlet point and from surrounding environment, induced the air that enters elephant trunk, reduced the pressure of elephant trunk discharging opening, thereby significantly reduced the airborne dust that discharging point produces, thereby reached antisoiling purpose.Therefore the utility model compared with prior art, the utility model not only has can effectively reduce the amount of air of inducing from elephant trunk inlet, reduce discharging point pressure, reduce the advantage of airborne dust, but also has simple in structure, good dustproof effect, advantage easy to use.Use the utility model can effectively improve the healthy of working environment, protection laborer.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment of the present utility model: when existing emission of baiting chute being prevented airborne dust from handling, utilize the differential pressure action of the air pressure at its emission of baiting chute discharging opening place greater than the air pressure at its inlet point place, the air that contains dust at emission of baiting chute discharging opening place is connected near in the close emission of baiting chute at inlet point place of pushing back communicating pipe of emission of baiting chute inlet point place by one, can reduces and prevent the airborne dust that emission of baiting chute discharging opening place produces so effectively.
During making, connect a communicating pipe 5 that communicates with the inner chamber of emission of baiting chute 1, and the lower port of communicating pipe 5 is arranged on discharging opening 3 places of close emission of baiting chute 1 at close its inlet point 2 places on the existing emission of baiting chute 1; In order more effectively to collect near the dust laden air the discharging opening 3, a trumpet-shaped reducing pipe 4 can connected on the lower port of communicating pipe 5; In order to reach better anti-airborne dust purpose, also can below the discharging opening 3 of emission of baiting chute 1, make the deflector chute 6 that can be arranged on the conveyer 8, and a traditional dust collection cover 7 is installed on deflector chute 6.
