Abstract
The utility model relates to a sealing device for screw ship unloader, screw axis including screw ship unloader, install the upper end gland through the asbestos packing on the screw axis, be located on the screw axis of upper end gland lower part and install the bottom end cover through the lip seal circle, extend at the bottom end cover top has the draw -in groove, the inner wall of draw -in groove is connected with the cooperation of the outer circumference of upper end gland, dustproof end cover is installed through the labyrinth seals device in the bottom of bottom end cover, dustproof end cover passes through the fastener and locks on the screw axis, the upper end gland becomes T font structure, is connected through stud between upper end gland and the bottom end cover, gland one end top is provided with the oil cup on being located, and the one end that is located the bottom end cover is passed through the hex bolts and is locked. This novel combination formula seal structure, it is compact reasonable, can reasonable realization prevent that the material dust from revealing, the in -service use effect is obvious, is fit for promoting.
Description
Technical field
The utility model relates to bulk solid loader and unloader tool technical field, especially a kind of sealing arrangement of bulk goods discharge system, specifically a kind of for the sealing dust-proof device in the screw ship unloader screw shaft of harbour.
Background technology
Screw ship unloader with the advantage of its high productivity, environmental protection gradually accept by people.Screw ship unloader is with the machinery of unloading a ship that is groundwork mechanism without the horizontal screw conveyer of flexible traction organ, vertical screw type conveyer and special take out device.Generally be used for unloading the bulk material such as cement, grain, be mainly used in the material unloading of port and pier cement transhipment station now.Cement has good flowing power, and form is dust-like, has all-pervasive characteristic, has very high requirement to the sealing effectiveness of this body structure of screw ship unloader.Once hermetically-sealed construction ging wrong producing very large dust, can have a negative impact to environment and working environment, causing more serious environmental pollution.The problem of sealing becomes in screw ship unloader the large problem needing to solve.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of sealing arrangement for screw ship unloader, thus it is reliable that equipment is closed, and dust can not occur and leak, cause environmental pollution.
The technical scheme that the utility model adopts is as follows:
A kind of sealing arrangement for screw ship unloader, comprise the screw shaft of screw ship unloader, described screw shaft is provided with upper end gland by asbestos packing, the screw shaft being positioned at gland bottom, upper end is provided with bottom end cover by lip-type packing, described bottom end cover top is extended with draw-in groove, the inwall of described draw-in groove and the excircle of upper end gland are connected, and the bottom of described bottom end cover is provided with dust-proof end cap by labyrinth gland, and described dust-proof end cap lock onto on screw shaft by fastener; Described upper end gland becomes T-shaped structure, and described upper end gland is connected by double end stud with between bottom end cover, and be positioned at top, gland one end, upper end and be provided with lubricating cup, the one end being positioned at bottom end cover is locked by hexagonal bar iron.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, rationally, by the effect of lip-type packing, asbestos packing and labyrinth gland, can reach good sealing effectiveness, resist dust and leak, reliability of service is good.
This novel combination type hermetically-sealed construction, compact and reasonable, can reasonably realize preventing material dust from revealing, and practical effect is obvious, is applicable to promoting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, double end stud; 2, upper end gland; 3, asbestos packing; 4, lip-type packing; 5, bottom end cover; 6, dust-proof end cap; 7, hexagonal bar iron; 8, lubricating cup; 9, screw shaft.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1, the sealing arrangement for screw ship unloader of the present embodiment, comprise the screw shaft 9 of screw ship unloader, screw shaft 9 is provided with upper end gland 2 by asbestos packing 3, the screw shaft 9 being positioned at upper end gland 2 bottom is provided with bottom end cover 5 by lip-type packing 4, bottom end cover 5 top is extended with draw-in groove, the inwall of draw-in groove and the excircle of upper end gland 2 are connected, the bottom of bottom end cover 5 is provided with dust-proof end cap 6 by labyrinth gland, and dust-proof end cap 6 lock onto on screw shaft 9 by fastener; The T-shaped structure of 2 one-tenth, upper end gland, is connected by double end stud 1 between upper end gland 2 with bottom end cover 5, and be positioned at top, upper end gland 2 one end and be provided with lubricating cup 8, the one end being positioned at bottom end cover 5 is locked by hexagonal bar iron 7.
The utility model adopts asbestos packing 3 in screw shaft 9 upper end, then upper end gland 2 is utilized to inject the greases such as butter, make asbestos packing 3, between screw shaft 9 and bottom end cover 5, form gluey fluid, cement or other dust just cannot pass through gelatinous medium, thus reach good sealing effectiveness, as long as after this timing injects grease by oil hole.
In order to well play sealing effectiveness below bottom end cover 5, have employed the dust-proof end cap 6 of labyrinth packing mode.Labyrinth packing namely by forming very little labyrinth gap to realize sealing between revolving part and connecting element.Fill with grease in gap.Be applicable to the structural environment that rotating speed is higher, in actual use, sealing effectiveness is better.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range, see claim, within protection domain of the present utility model, can do any type of amendment.
