Abstract
The utility model relates to a part of a superpave gyratory compactor (SGC) form scraping plate type coal boiler slag discharging machine, in particular to a bottom bearing sealing device for a scraping plate type coal boiler slag discharging machine. The bottom bearing sealing device mainly solves the problems that in the prior art, the sealing is difficult to ensure, when the sealing failure occurs, cooling water and coal ash slag particles and sand in the cooling water simultaneously flow into a bearing seat, the accelerated abrasion of a sliding bearing is caused, even the clamping is caused, in addition, a driven chain wheel shaft can leftwards and rightwards move in the operation process, and the technical problems of chain disengagement of a chain of the slag discharging machine, scrapper deformation and the like are caused, so the service life of the slag discharge machine is reduced. The bottom bearing sealing device comprises a bearing seat (1), wherein one end of the bearing seat is provided with a bearing press cover (2), a sliding bearing (3) is arranged inside the bearing seat, and a driven chain wheel shaft (4) is connected in the sliding bearing in a penetrating way. The bottom bearing sealing device is characterized in that a labyrinth sealing sleeve (5) is arranged inside the other end of the bearing seat (1), and the labyrinth sealing sleeve extends out of the inner surface of the bearing seat and is in contact onto the outer surface of the driven chain wheel shaft (4).
Description
Technical field
The utility model relates to a kind of component of SGC type scraper-type coal burning boiler slagging machine, especially relates to a kind of scraper-type coal burning boiler slagging machine bottom bearing seal arrangement.
Background technique
Filter plant is widely used in production fields such as oil, medicine, chemical industry, environmental protection, in the numerous kinds filter plant that uses at present, owing to there is not supporting tapping mechanism, can't directly obtains dried slag, and the step of slagging tap need be set separately on technology.Chinese patent discloses a kind of rolling chain scraper slagging machine (publication number: CN2259381); It comprises: between motor drives drive sprocket and the driven sprocket running; Assembling drive chain, chain are uniformly distributed with between laterally assembles wheel on axle, cooperate do rolling friction with base plate; On axle,, do to promote to carry to cooperate with the material on the base plate with the scraper arm assembling scraper plate parallel with axle; In promoting the conveying material process, distance is 3～6 millimeters between the scraper plate in wheel the place ahead and base plate; Be acute angle with the wheel excircle section angle of the linear touch scrolling of base plate.But this slagging machine bottom bearing just relies on an oil sealing to seal, and the distinct disadvantage that this structure exists is: owing to contain a large amount of coal ash solid impurity particle and silt in the cooling water of slagging machine inside, oil sealing, sliding bearing and driven chain wheel shaft are easy to be worn; Like Fig. 1; Difficult sealing is to guarantee that once seal failure, coal ash solid impurity particle and silt in cooling water and the cooling water flow in the bearing support in the lump; Cause sliding bearing accelerated wear test, in addition stuck; On the other hand since slagging machine in running, the driven chain wheel shaft is meeting left and right sides play in rotation, causes the slagging machine chain to take off chain, phenomenons such as scraper distortion, the working life of reducing slagging machine.
The model utility content
The utility model provides a kind of scraper-type coal burning boiler slagging machine bottom bearing seal arrangement, and it mainly is to solve the existing in prior technology difficult sealing to guarantee, once seal failure; Coal ash solid impurity particle and silt in cooling water and the cooling water flow in the bearing support in the lump, cause sliding bearing accelerated wear test, even stuck; And the driven chain wheel shaft is meeting left and right sides play in rotation; Cause the slagging machine chain to take off chain, technical problems such as scraper distortion, thereby the working life of reducing slagging machine.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of scraper-type coal burning boiler slagging machine bottom bearing seal arrangement of the utility model: comprise bearing support; Bearing support one end is provided with bearing gland; Bearing support inside is provided with sliding bearing; Cross-under has the driven chain wheel shaft in the sliding bearing, and described bearing support the other end inside is provided with the labyrinth seal cover, and labyrinth seal cover projecting shaft socketed inner surface and contact are on the outer surface of driven chain wheel shaft.The utility model has been cancelled oil sealing and jump ring on original bearing support, make it into labyrinth seal cover, and the labyrinth seal cover is lengthening suitably; Can protrude from bearing support when making it be assemblied on the bearing support; Behind the labyrinth seal cover lengthening, play the positioning action of driven chain wheel shaft, thereby reduce left and right sides play in the driven chain wheel shaft rotation process; Cause the slagging machine chain to take off chain, phenomenons such as scraper distortion.
As preferably, establish on the described bearing support and have top wire hole, be provided with in the top wire hole on the outer surface that jackscrew withstands on labyrinth seal cover.On bearing support, increase by two top wire holes, can prevent labyrinth seal cover and the transfer of driven chain wheel shaft.
As preferably, being connected with on the described bearing gland can be to the cleaning hose of sliding bearing bath.On bearing gland, increase a cleaning hose, flushing sliding bearing and labyrinth seal prevent that coal ash solid impurity particle and silt from flowing in the bearing support in the lump.
Therefore, the utlity model has that overall structure is simple, installation, maintenance is convenient, effectively reduces the slagging machine fault, prolongs the working life of slagging machine; After using the labyrinth seal cover instead, the coal ash solid impurity particle and the silt that effectively reduce in the cooling water flow in the bearing support together, prevent to cause characteristics such as sliding bearing accelerated wear test even stuck phenomenon.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of former seal arrangement;
Accompanying drawing 2 is a kind of structural representations of the utility model.
Component, position and numbering among the figure: bearing support 1, bearing gland 2, sliding bearing 3, driven chain wheel shaft 4, labyrinth seal cover 5, top wire hole 6, jackscrew 7, cleaning hose 8.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
Embodiment: this example is a kind of scraper-type coal burning boiler slagging machine bottom bearing seal arrangement, like Fig. 2, a bearing support 1 is arranged, and bearing support one end is provided with bearing gland 2, and being connected with on the bearing gland can be to the cleaning hose 8 of sliding bearing 3 baths.Bearing support inside is provided with sliding bearing 3; Cross-under has driven chain wheel shaft 4 in the sliding bearing; Bearing support 1 the other end inside is provided with labyrinth seal cover 5; Labyrinth seal cover projecting shaft socketed inner surface and contact are established on the bearing support and are had top wire hole 6 on the outer surface of driven chain wheel shaft, are provided with in the top wire hole on the outer surface that jackscrew 7 withstands on labyrinth seal cover 5.
During use, cleaning hose 8 can wash sliding bearing 3, reduces the wearing and tearing of sliding bearing; And 5 interior coal ash solid impurity particle and silt recoils are overlapped in labyrinth seal go back; Behind labyrinth seal cover 5 lengthenings, play the positioning action of driven chain wheel shaft 4, thereby reduce left and right sides play in the driven chain wheel shaft rotation process; Cause the slagging machine chain to take off chain, phenomenons such as scraper distortion.
The above is merely the specific embodiment of the utility model; But the structure characteristic of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
