Abstract
The utility model provides an electric dust-removing rapping bearing of a sintering and pelletizing machine head, which consists of a rapping shaft, a shaft sleeve, a roller, a pin shaft and a bearing. The roller adopts a 6-wheel structure, so that stress supporting points are increased, and the wear resistance of the roller is enhanced. Meanwhile, the lengths of the roller and the pin shaft are correspondingly increased, so that the abrasion resistance of main parts of the novel bearing is improved by more than 78% compared with that of a bearing with a 3-wheel structure, and the service life is prolonged by more than 2000 h. The electric field with serious abrasion is applied, and the requirement of continuous and stable operation of the easy-abrasion part of the electric dust removal equipment under the large environment of realizing dynamic maintenance in production operation can be completely met. Under the condition that the cost is only increased by 5%, the stable service life of the 6-wheel bearing is increased by nearly 1 time compared with that of the 3-wheel bearing, and the economic benefit is very obvious.
Description
Technical field
The utility model belongs to sintering dust plant equipment, particularly a kind of agglomerates of sintered pellets head electric precipitation vibrated system bearing.
Background technology
At present, domestic conventional Large-sized Electrostatic Precipitator mainly contains side vibration shape electric cleaner and two kinds, top vibration shape electric cleaner.Side vibration shape electric cleaner cathode and anode rapping generally adopts the tangential rapping structure of side direction transmission, and Comparatively speaking, the reliability of side direction transmission rapping is better, but its stable service life is relatively short.Particularly when roasting unit entirety requires to realize dynamically overhauling, side vibration shape electric precipitation side direction transmission rapping apparatus can not realize dynamic maintenance because consumable accessory is arranged in flue gas circulating area.Existing side vibration shape electric cleaner, for cathode rapping, is generally made up of parts such as drive unit, rapping bearing, rapping shaft, cathode frames.Wherein rapping shaft contracts parts such as drawing together rapping shaft, axle sleeve, roller, bearing pin and bearing bracket stand.In production run, roller then often becomes the main easily worn part of rapping apparatus and even whole electric cleaner.Because bearing adopts based on the version of 3 rollers, namely 3 rollers divide three groups, are triangular in shapely distributed in outside bearing bracket stand internal axle sleeve, and easy to wear, the life-span is low.This kind of form structure is fairly simple, under severe working condition, very easily occur wear damage.Especially three roller distributions triangular in shape, below two roller stress comparatively large, be often damaged.So, must improve the rapping bearing of existing three-wheel form.
Summary of the invention
The purpose of this utility model is the stable service life in order to improve side vibration shape electric cleaner side direction transmission rapping apparatus, existing electric cleaner side direction transmission rapping bearing is improved, thus provide a kind of rational in infrastructure, wearability is good, the agglomerates of sintered pellets head electric precipitation rapping bearing of long service life.
For this reason, the technical solution of the utility model is:
A kind of agglomerates of sintered pellets head electric precipitation rapping bearing, comprises rapping shaft, axle sleeve, roller, bearing pin and bearing; It is characterized in that, roller adopts 6 versions of taking turns, and namely on the bearing pin of three groups of rollers, installs two rollers side by side.
The length of described roller is 32 ~ 36mm.
The length of described bearing pin is 88 ~ 92mm.
The utility model has the advantages that:
Improved agglomerates of sintered pellets head electric precipitation rapping bearing, because roller adopts 6 versions of taking turns, add the stressed strong point, roller wear resistance is strengthened, and the service life of bearing increases greatly.Simultaneously due to the length of the length and bearing pin that increase roller accordingly, make the wear resistance of novel bearing critical piece improve 78 more than ﹪ compared with the bearing of 3 wheel constructions, service life is higher than 2000h.At the electric field that wearing and tearing are comparatively serious, apply it, can meet completely under production run realizes the overall situation of dynamically maintenance, the needs of electric dust-removing equipment vulnerable part continuous and steady operation.When cost only increases by 5 ﹪, the stable service life of 6 wheel bearings adds nearly 1 times compared with 3 wheel bearings, economic benefit highly significant.
Accompanying drawing explanation
Fig. 1 is agglomerates of sintered pellets head electric precipitation rapping shaft bearing structure schematic diagram.
Fig. 2 is the side view of Fig. 1.
In figure: power transmission shaft 1, axle sleeve 2, roller 3, bearing pin 4, bearing 5.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in detail:
A kind of agglomerates of sintered pellets head electric precipitation rapping bearing, as shown in Figures 1 and 2, be by power transmission shaft 1, axle sleeve 2, roller 3, bearing pin 4 and bearing bracket stand 5 are formed.Bearing bracket stand 5 is widened 50mm, for installing two roller 3 slot millings side by side; Roller 3 diameter 40mm, length is increased to 35 ㎜ by 25 ㎜, and changing two into by single one group is one group, and 6 rollers 3 are three groups; The length of bearing pin 4 is increased to 90 ㎜ by 40 ㎜, is arranged on side by side by roller 3 on bearing pin 4, is triangular in shapely distributed in outside axle sleeve 2, is fixed in bearing bracket stand 5 by bearing pin 4.
