Compared with the prior art, the sealing device is novel and simple in structure, reasonable in design and convenient to maintain, dust cannot gather at gaps of the sprocket shaft and the shaft hole of the sprocket casing, so that the sealing effect is achieved, and the service life of the seal ring is prolonged remarkably.
Description
[technical field]
The utility model relates to the conveying technology field of solid powder, grain, sheet material, specifically a kind of pipe chain conveyor sealing device.
[background technology]
When pipe chain conveyer is for delivery of solid, powdery material and while being in tilted layout, fine powder falls into the gap of sprocket shaft and chain-wheel box axis hole in a large number, because a large amount of dust accumulations is in gap, cause the easy damage of this place's sealing member and sprocket shaft to rotate and be subject to jam, had a strong impact on the service life of seal ring etc., and maintenance is also very inconvenient.
[utility model content]
The purpose of this utility model is exactly will solve above-mentioned deficiency and a kind of pipe chain conveyor sealing device is provided, make dust can not be gathered in the gap of sprocket shaft and chain-wheel box axis hole, thereby reach sealing effectiveness, and simple in structure, maintenance is convenient, significant prolongation the service life of seal ring.
Design for achieving the above object a kind of pipe chain conveyor sealing device, comprise chain-wheel box 1 and sprocket shaft 2, on described sprocket shaft 2, be arranged with seal ring 3 and bearing 4, described sprocket shaft 2 ends are provided with bearing gland 5, the interior axis hole of described chain-wheel box 1 place has additional axle sealing gland lid 6, described axle sealing gland lid 6 is arranged on seal ring 3 places on sprocket shaft 2, the axis hole place of described axle sealing gland lid 6 has multiple tracks groove 7, on described axle sealing gland lid 6 end face adjacent with seal ring 3, have circumferential groove 8 and radial slot 9, described circumferential groove 8, radial slot 9 are connected with groove 7.
Described circumferential groove 8 connects outside blanket gas entrance 10 by pipeline.
Described groove 7 is provided with at least more than twice, and described groove 7 cross-sectional planes are semicircle.
The utility model compared with the existing technology, novel structure, simple, because axis hole place in chain-wheel box has additional axle sealing gland lid, and have multiple tracks groove at axle sealing gland lid axis hole place and have circumferential groove and radial slot on axle sealing gland lid end face, this circumferential groove, radial slot are connected with groove, by introducing blanket gas at sprocket shaft and chain-wheel box axis hole place, blanket gas is blown into groove through circumferential groove and radial slot, thereby make dust can not be gathered in the gap of sprocket shaft and chain-wheel box axis hole, finally reach good sealing effectiveness; In addition, sealing arrangement described in the utility model is reasonable in design, maintenance convenient, significant prolongation the service life of seal ring.
[brief description of the drawings]
Fig. 1 is structural representation of the present utility model;
In figure: 1, chain-wheel box 2, sprocket shaft 3, seal ring 4, bearing 5, bearing gland 6, axle sealing gland lid 7, groove 8, circumferential groove 9, radial slot 10, blanket gas entrance.
[detailed description of the invention]
Below in conjunction with accompanying drawing, the utility model is done to following further illustrating:
As shown in Figure 1, the utility model comprises: chain-wheel box 1 and sprocket shaft 2, on sprocket shaft 2, be arranged with seal ring 3 and bearing 4, sprocket shaft 2 ends are provided with bearing gland 5, the interior axis hole of chain-wheel box 1 place has additional axle sealing gland lid 6, axle sealing gland lid 6 is arranged on seal ring 3 places on sprocket shaft 2, the axis hole place of axle sealing gland lid 6 has multiple tracks groove 7, this groove 7 is provided with at least more than twice, groove 7 cross-sectional planes are semicircle, on axle sealing gland lid 6 end face adjacent with seal ring 3, have circumferential groove 8 and radial slot 9, circumferential groove 8 connects outside blanket gas entrance 10 by pipeline, circumferential groove 8, radial slot 9 is connected with groove 7.
The utility model relates to the conveying of solid powder, grain, sheet material, specifically a kind of equipment of carrying the material of these types in certain limit and space.In order to solve the existing a large amount of dust accumulations of prior art in the gap of sprocket shaft and chain-wheel box axis hole, cause this place's sealing member rapid wear, sprocket shaft to rotate the problem that is subject to jam, the utility model is introduced blanket gas at sprocket shaft and chain-wheel box axis hole place.For realizing this function, the utility model axis hole place in chain-wheel box increases by an axle sealing gland lid, the axis hole place of axle sealing gland lid has multiple tracks groove, axle sealing gland lid cover plate face has circumferential groove and multiple tracks radial slot, the blanket gas of introducing from outside is blown into groove through circumferential groove and radial slot, thereby make dust can not be gathered in the gap of sprocket shaft and chain-wheel box, thereby reach sealing effectiveness, extended the service life of the sealing members such as seal ring.
The utility model is not subject to the restriction of above-mentioned embodiment; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
