Abstract
The utility model discloses an outside sealing device for a screw conveyer. The outside sealing device comprises a U-shaped housing; two pieces of inverted U-shaped steel are symmetrically connected onto two outer sides at the upper part of the U-shaped housing; an inverted U-shaped cover plate is correspondingly arranged at the top of the U-shaped housing; a sealing strip is arranged between the upper plane of each piece of inverted U-shaped steel and the inverted U-shaped cover plate; and the upper planes of the two pieces of inverted U-shaped steel and the inverted U-shaped cover plate are fixedly connected through a plurality of bolt assemblies. The two pieces of inverted U-shaped steel are welded on two sides of the housing, the cover plate is designed into an inverted U-shaped structure, two sides of the inverted U-shaped cover plate are jointed with an externally-vertical planes of the two pieces of inverted U-shaped steel, and in addition, the sealing strip is arranged between the cover plate and the piece of inverted U-shaped steel, so that dust leakage during the material conveying process is effectively prevented.
Description
Technical field
The utility model relates to a kind of conveyor screw outer seal device.
Background technology
Existing conveyor screw reaches sealing effectiveness by exterior housing and cover plate, and housing (as shown in Figure 1) generally is bent into the ∪ font by the steel plate of certain-length, and top and the both sides angle steel of burn-oning makes its fixing shaping.Top is covered with cover plate, owing to have welding deformation between both sides angle steel and the housing, is difficult to guarantee fine applying between the plane on cover plate and the angle steel, when conveying powder material, just has dust and gush contaminated environment from the slit like this.
The utility model content
The technical problems to be solved in the utility model is the defective that overcomes prior art, and a kind of conveyor screw outer seal device of good airproof performance is provided.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of conveyor screw outer seal device, comprise " U " font housing, two outsides, described " U " font housing top are symmetrically connected with down " recessed " Zee bar steel Z, described " U " font case top is provided with down " recessed " font cover plate accordingly, the described plane of falling on " recessed " Zee bar steel Z is provided with sealing band between " recessed " font cover plate with falling, and captives joint by a plurality of bolt assemblies in the described plane of falling on " recessed " font cover plate and " recessed " Zee bar steel Z.
Further, described " U " font housing with fall the connection mode of " recessed " Zee bar steel Z and be welding.
Further, described sealing band is rubber weather strip or asbestos board sealing band.
The beneficial effects of the utility model: the both sides welding of the utility model housing is " recessed " Zee bar steel Z, simultaneously cover plate also is designed to down " recessed " font, " recessed " font cover plate both sides and the outer upright plane applying of " recessed " Zee bar steel Z, cover plate and fall and also to be covered with sealing band between the plane on " recessed " Zee bar steel Z has effectively prevented the leakage of dust in the material conveying process in addition.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and constitutes the part of specification sheets, is used from explanation the utility model with embodiment one of the present utility model, does not constitute restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of existing conveyor screw outer seal device;
Fig. 2 is the structural representation of the utility model conveyor screw outer seal device.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
As shown in Figure 2, a kind of conveyor screw outer seal device, comprise " U " font housing 1, two outsides, described " U " font housing 1 top are symmetrically connected with down " recessed " Zee bar steel Z 2, described " U " font housing 1 top is provided with down " recessed " font cover plate 4 accordingly, described fall on " recessed " Zee bar steel Z 2 plane with fall 4 of " recessed " font cover plates and be provided with sealing band 3, described fall " recessed " font cover plate 4 with fall on " recessed " Zee bar steel Z 2 plane and captive joint by a plurality of bolt assemblies (representing whole among the figure).
Described sealing band is a rubber weather strip.
Described " U " font housing 1 with fall the connection mode of " recessed " Zee bar steel Z 2 and be welding.
" recessed " font cover plate 4 both sides and the outer upright plane applying of " recessed " Zee bar steel Z 2.Bolt 5 and nut 6 screws thread fit, 6 on bolt 5 and nut are provided with pad 7.Sealing structure after the improvement is good, has stopped the leakage of dust.
The difference of embodiment 2 and embodiment 1:
Described sealing band is the asbestos board sealing band.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
