SUMMERY OF THE UTILITY MODEL

The utility model discloses the main technical problem who solves provides a feed screw conveyer's sealed improved structure, adopts the play tuber pipe on sealed bellows structure and the conveyer casing to cooperate for the sealed wind that gets into in the casing distributes evenly, and pressure is big.

In order to solve the technical problem, the utility model discloses a technical scheme be: a seal improving structure of a feed screw conveyor, comprising: the air-out pipe comprises a base support, a variable frequency motor arranged above the base support and a screw conveyor driven by the variable frequency motor, wherein a sealing air box is arranged on a shell outer cover of the screw conveyor, a sealing air interface is arranged at the top of the sealing air box, a plurality of air-out pipes are arranged on three side inner walls of the shell positioned on the sealing air box cover and around the uniform distribution, and included angles are formed between the air-out pipes and the inner wall of the shell and are 40-50 degrees.

In a preferred embodiment of the present invention, the sealing bellows is welded to the housing and located at a third of the rear portion of the housing.

In a preferred embodiment of the present invention, the sealing air interface is a flange interface.

In a preferred embodiment of the present invention, the air outlet pipe is an inch steel pipe welded to the top wall and the two side walls of the housing.

In a preferred embodiment of the present invention, the included angle is 45 degrees.

In a preferred embodiment of the present invention, the screw conveyer has a dual screw shaft structure, and a plurality of paddles for stirring the material are disposed around each screw shaft.

In a preferred embodiment of the present invention, a fire sprinkler is disposed in the housing behind the sealing bellows.

The utility model has the advantages that: the sealing air box structure is matched with the air outlet pipe on the conveyor shell, so that sealing air entering the shell is uniformly distributed, the pressure is high, and the next conveying equipment can safely and reliably run.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an improved sealing structure for a feeding screw conveyor, including: base support 1, set up in inverter motor 2 of base support top and by inverter motor driven screw conveyer 3, screw conveyer's 4 dustcoats of casing are equipped with sealed bellows 5, and sealed bellows's top is provided with sealed wind interface 6, and is concrete, sealed bellows with casing welded connection, and be located the casing is close the third department of afterbody, and sealed wind interface adopts the flange interface, is provided with a plurality of play tuber pipes 7 around the equipartition on the three side inner walls that sealed bellows cover established on the casing, and the rear that lies in sealed bellows in the casing is provided with fire sprinkler 11, and wherein, play tuber pipe is for welding the one inch steel pipe on casing roof and both sides wall, and sealed bellows structure cooperatees with the play tuber pipe on the conveyer casing for sealed wind in the entering casing distributes evenly, and pressure is big, be formed with the contained angle between play tuber pipe and the shells inner wall, the contained angle is 40 degrees-50 degrees, and is preferred, and the contained angle sets up to 45 degrees.

Specifically, screw conveyer adopts two screw axis structures, the screw axis includes relative first screw axis 8 and the second screw axis 9 that sets up, form the pay-off passageway between first screw axis and the second screw axis, it is provided with a plurality of plectrums 10 that are used for stirring the material to surround on every screw axis, two sets of screw axes are connected with inverter motor respectively, the discharge gate is located the position directly over between first screw axis and the second screw axis, in use, after the material gets into the casing from the feed inlet, fall into between first screw axis and the second screw axis, first screw axis and second screw axis are relative rotation, break up the material that falls down, the split, the material after breaking up passes through the discharge gate ejection of compact, get into subsequent handling, the discharge gate sets up under the pay-off passageway, make things convenient for the transport of material.

The utility model relates to a feed screw conveyer's sealed beneficial effect who improves structure is: the sealing air box structure is matched with the air outlet pipe on the conveyor shell, so that sealing air entering the shell is uniformly distributed, the pressure is high, and the next conveying equipment can safely and reliably run.

The above-mentioned only be the embodiment of the utility model, not consequently the restriction the patent scope of the utility model, all utilize the equivalent structure or equivalent flow transform that the content of the specification was done, or directly or indirectly use in other relevant technical field, all the same reason is included in the patent protection scope of the utility model.
