Abstract
The utility model discloses a stirring shaft sealing device capable of preventing sand from entering, relating to the technical field of rotating shaft sealing. The stirring shaft sealing device comprises a stirring shaft; a shaft sleeve is wrapped on the outer wall of the stirring shaft; the outer side of the shaft sleeve is provided with a sealing holder; a teflon bearing and shaft sealing packing are arranged between the sealing holder and the shaft sleeve; the teflon bearing is arranged above the shaft sealing packing; the upper end of the teflon bearing is provided with a sliding bearing cage fixed on the upper end of the sealing holder; the lower end of the shaft sealing packing is provided with a packing gland; the upper end of the sliding bearing cage is provided with a sand guard; and the sand guard is fixed on the outer wall of the stirring shaft. The stirring shaft sealing device is reasonable in structural design, capable of effectively preventing small sand grains mixed in raw materials from entering a rotary contact surface gap to generate abrasion, increasing the abrasion range of the stirring shaft due to the contact between the shaft sleeve and a sealing assembly and adjusting the sealing effect through a bolt arranged on the packing gland after the shaft sleeve is worn, simple and convenient to replace and low in maintenance cost when the shaft sleeve is seriously worn.
Description
Technical field:
The utility model relates to the rotation axis seal technical field, relates in particular to a kind of into husky shaft sealing device of preventing.
Background technology:
For a long time, the sealing problem of rotating shaft always is a difficult problem that perplexs people; In particular for industrial agitated reactor, often all the environment of HTHP in the kettle, after equipment uses a period of time; Can wear and tear to some extent unavoidably, this moment, the problem of shaft difficult sealing was just particularly outstanding.For example, the agitated reactor that is used for beer gelatinization and saccharifying is commonly called as adjunce copper and brew kettle, just exists shaft easily by the grains of sand in the raw material and dust wearing and tearing, the problem of sealing difficulty.In gelatinization process, the tiny grains of sand of carrying secretly in the raw material can enter between shaft and the seal, thereby quicken the wearing and tearing of shaft, cause the service life of shaft short, need often to change, and sealing effectiveness is poor, and maintenance cost is high.
The utility model content:
The utility model technical problem to be solved is to overcome the defective of prior art, and a kind of into husky shaft sealing device of preventing is provided, and can prevent effectively that the tiny grains of sand of carrying secretly in the raw material from getting into wearing and tearing shaft in the rotation contact-making surface gap.
The utility model technical problem to be solved adopts following technical scheme to realize:
A kind ofly prevent into husky shaft sealing device, comprise shaft, it is characterized in that: said shaft outer wall is enclosed with axle sleeve; The axle sleeve arranged outside has seal receptacle; Be provided with between seal receptacle and the axle sleeve and gather tetrafluoro bearing and shaft packing, the said tetrafluoro bearing that gathers is above shaft packing, and the said tetrafluoro bearing upper end of gathering is provided with the sliding bearing cover and is fixed on the seal receptacle upper end; Said shaft packing lower end is provided with gland; Said sliding bearing cover upper end is provided with anti-sand cover, and anti-sand cover is fixed on the shaft outer wall, rotates with axle.
Said axle sleeve is fixedly connected on the shaft outer wall through screw, and axle sleeve together rotates with shaft, and shaft packing contacts with the axle sleeve outer wall, thereby the protection shaft is not worn, and after the axle sleeve wearing and tearing, for shaft, it is convenient to change, and cost is lower.
Said gland is the lower end that L shaped, L shaped gland one end is pressed on shaft packing, and the other end is through being bolted to the lower end of seal receptacle; After the wearing and tearing of axle sleeve outer wall; Can regulate the thrust of gland through regulating bolt, behind the shaft packing pressurized deformation take place shaft packing; Thereby with the axle sleeve outer wall fit tightr, sealing effectiveness is better.
Said anti-sand cover outer is to being arranged with the right angle flange that is wrapped in the sliding bearing cover, and the slit of axle sleeve and black box contact-making surface is covered from the upper end, prevents that the tiny grains of sand of carrying secretly in the raw material from getting into.
The utility model reasonable in design can prevent effectively that the tiny grains of sand of carrying secretly in the raw material from getting into the wearing and tearing that produce in the rotation contact-making surface gap, is provided with axle sleeve and contacts with black box; Can protect shaft not to be worn; After the axle sleeve wearing and tearing, can regulate sealing effectiveness through the bolt on the gland, during the axle sleeve serious wear; Change simple and conveniently, maintenance cost is low.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind ofly prevent into husky shaft sealing device, comprise shaft 1; Shaft 1 outer wall is enclosed with axle sleeve 8, and axle sleeve 8 arranged outside have seal receptacle 5, is provided with between seal receptacle 5 and the axle sleeve 8 to gather tetrafluoro bearing 4 and shaft packing 6; Gather tetrafluoro bearing 4 above shaft packing 6; Gather tetrafluoro bearing 4 upper ends and be provided with sliding bearing cover 3 and be fixed on seal receptacle 5 upper ends, shaft packing 6 lower ends are provided with gland 7, and sliding bearing cover 3 upper ends are provided with anti-sand cover 2; Anti-sand cover 2 is fixed on shaft 1 outer wall; Anti-sand cover 2 outers cover the slit of axle sleeve 8 with the black box contact-making surface to being arranged with the right angle flange that is wrapped in the sliding bearing cover from the upper end, prevent that the tiny grains of sand of carrying secretly in the raw material from getting into.
Axle sleeve 8 is fixedly connected on shaft 1 outer wall through screw, and axle sleeve 8 together rotates with shaft 1, and shaft packing 6 contacts with axle sleeve 8 outer walls; Thereby protection shaft 1 is not worn, after axle sleeve 8 wearing and tearing, for shaft 1; It is convenient to change, and cost is lower.Gland 7 is the lower end that L shaped, L shaped gland one end is pressed on shaft packing 6, and the other end is through being bolted to the lower end of seal receptacle 5; After the wearing and tearing of axle sleeve 8 outer walls; Can be through regulating bolt, deformation takes place behind shaft packing 6 pressurizeds in the thrust of regulating 7 pairs of shaft packings 6 of gland; Thereby with axle sleeve 8 outer walls fit tightr, sealing effectiveness is better.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
