Abstract
The invention relates to a shaft end sealing device of a dry-mixed mortar mixer. The shaft end sealing device comprises a mixing shaft and a barrel, a wear-proof sleeve is fixed on an outer ring of the mixing shaft, two sealing rings are arranged between a flange and the wear-proof sleeve and are spaced by a spacing sleeve so that an enclosed space is formed among the two sealing rings, the spacing sleeve and the wear-proof sleeve, and lubricating grease is filled in the enclosed space and achieves sealing as well as lubricating. The two sealing rings and the spacing sleeve are connected with the flange through a compressing sleeve, a grease cup is connected on the compressing sleeve, the lubricating grease is filled into the enclosed space via the grease cup, the sealing rings and a grease hole in the spacing sleeve, and the flange is connected with the barrel through bolts. The shaft end sealing device has the advantages that standby sealing rings can be replaced without detaching bearing seats by the aid of the split type spacing sleeve and the compressing sleeve, and the shaft end sealing device is convenient and reliable to use, good in sealing performance and convenient and timesaving for sealing part replacement.
Description
Technical field
The present invention relates to a kind of shaft end seal device of dry-mixed mortar stirrer.
Background technique
In dry-mixed mortar production line, stirrer is equipment most crucial in the whole production line, and its Performance And Reliability is directly connected to the Quality and yield of mortar product, and the reliability key of solution dry-mixed mortar stirrer is the shaft end seal problem.The main shaft sealing construction of dry-mixed mortar stirrer has two kinds of forms at present, and a kind of is hermetic seal, and another kind is grease sealing.Fig. 1 is the air-tight structure figure of dry-mixed mortar stirrer axle head, the air input joint 6 of pressurized air on seal 5 enters air chamber 3, the pressurized air that enters air chamber 3 is blown into the inside of cylindrical shell 4 along the annulus 2 of axle 1, stop the material of cylindrical shell 4 inside to enter air chamber 3, realize sealing, the reliability of this hermetic seal is relatively poor, the control difficulty, need the often powder of cleaning air chamber inside, in case clear up untimelyly, main shaft will be worn even scrap, and cleaning is got up pretty troublesome, not environmental protection, working life is shorter; And grease sealing will often be changed Sealing, need to dismantle bearing support when changing Sealing, not only bothers but also delay the production time.So the sealing problem of dry-mixed mortar stirrer main shaft never is well solved.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this invention is to provide a kind of shaft end seal device of dry-mixed mortar stirrer, good sealing effect, easy to use and reliable, Sealing is changed convenient and time-saving.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of sealing structure of shaft end of dry-mixed mortar stirrer, comprise stirring shaft, cylindrical shell, outer ring at stirring shaft is fixed with wear-resistant sleeve, between flange and wear-resistant sleeve, be provided with two seal rings, separate by spacer between two seal rings, so just form the space of a sealing between two seal rings, spacer and wear-resistant sleeves, described seal space is full of lubricating grease, not only plays the effect of sealing but also play lubricated effect; Two seal rings and spacer are connected with flange by clamping sleeve, are connected with lubricating cup on the clamping sleeve, and the oilhole through lubricating cup, seal ring and spacer inside fills lubricating grease to confined space; Flange is connected with cylindrical shell by bolt.
Described spacer, clamping sleeve are separate type.
Described stirring shaft outer ring also is socketed with backup seal.
Described backup seal is made of nitrile butadiene rubber.
Described wear-resistant sleeve plating hard chromium on surface.
Described lubricating grease is lithium grease.
Compared with prior art, the invention has the beneficial effects as follows:
Utilize separated type spacer, clamping sleeve, can in the situation of not tearing bearing support open, change backup seal, easy to use and reliable, good sealing effect, Sealing is changed convenient and time-saving.

Embodiment
Below in conjunction with Figure of description the present invention is described in detail, but should be noted that enforcement of the present invention is not limited to following mode of execution.
See Fig. 2-Fig. 7, a kind of sealing structure of shaft end of dry-mixed mortar stirrer, comprise stirring shaft 1, cylindrical shell 4, flange 9, wear-resistant sleeve 8, spacer 10, clamping sleeve 12, seal ring 11, axle journal outer ring at stirring shaft 1 is fixed with wear-resistant sleeve 8, between flange 9 and wear-resistant sleeve 8, be provided with two seal rings 11, separate by spacer 10 between two seal rings 11, so between two seal rings 11, spacer 10 and wear-resistant sleeve 8, just form the space of a sealing, described seal space is full of lubricating grease, not only plays the effect of sealing but also play lubricated effect; Two seal rings 11 and spacer 10 are connected with flange 9 by clamping sleeve 12, are connected with lubricating cup 13 on the clamping sleeve 12, and the oilhole through lubricating cup 13, seal ring 11 and spacer 10 inside fills lubricating grease to confined space; Flange 9 is connected with cylindrical shell 4 by bolt.
Described spacer 10, clamping sleeve 12 are separate type.
Described stirring shaft 1 outer ring also is socketed with backup seal 14.
Described backup seal 14 is made of nitrile butadiene rubber.
Described wear-resistant sleeve 8 plating hard chromium on surface.
Described lubricating grease is lithium grease.
Shaft end seal between flange 9 and wear-resistant sleeve 8 is realized by two seal rings 11, separate by spacer 10 between two seal rings 11, the path of seal ring 11 stretches to the inside of cylindrical shell 4, between two seal rings 11, spacer 10 and wear-resistant sleeve 8, just form like this space of a sealing, this enclosed space is full of lubricating grease, not only plays the effect of sealing but also play lubricated effect; Two seal rings 11 and spacer 10 are connected with flange 9 by clamping sleeve 12, are connected to lubricating cup 13 on the clamping sleeve 12, fill lubricating grease through lubricating cup 13, seal ring 11 and spacer 10 inner oilholes to confined space; Spacer 10, clamping sleeve 12 are separated type, and this structure is not only used reliably, and change backup seal 14 very convenient, save time.
General, the backup seal 14 of each axle head is joined four ~ six, and material is nitrile butadiene rubber, and thickness is 8mm.In order to increase wear resistance, improve working life, the plating hard chromium on surface of wear-resistant sleeve 8.Shaft end seal can adopt lithium grease No. 2, each axle head, and the lubricating grease consumption of each class is 5 ~ 10ml.
The present invention utilizes separated type spacer, clamping sleeve, can change backup seal in the situation of not tearing bearing support open, and is easy to use and reliable, good sealing effect, and Sealing is changed convenient and time-saving.
