Abstract
The utility model relates to a roller screen which is used for sieving graininess coal in a coal conveying system of a thermal power plant. The utility model is composed of a large base, a screen strip shaft, a sealing box body, etc. The screen surface of the roller screen is arranged in a sloping shape corresponding to a horizontal plane. The sealing box body is split into two parts of a lower box and an upper box at the center of the screen strip shaft of the roller screen, the upper box is divided into three segments of a front box, a middle box and a back box, and the transmission of the screen strip shaft adopts the transmission of a bush roller chain. The roller screen has the advantages of good sieving effect, low equipment failure rates, easy disassembly, assembly and maintenance, etc.
Description
The utility model belongs to the screening plant technical field, relates to a kind of coal-fired roller picker of thermal power plant coal handling system screening that is used for.
Roller picker is the visual plant in coal-fired station's coal handling system, its effect is that the coarse coal screening that qualified coal of the granularity that will successively transport on the belt conveyor and granularity transfinite is opened, qualified coal enters milling equipment to make granularity, allows coarse coal that granularity transfinites enter coal breaker by the compass screen surface of roller picker simultaneously and pulverizes.At present used traditional roller picker is made of motor, reductor, big base, sieve bobbin and the parts such as seal case that cover on the sieve bobbin in coal-fired station, sieving wherein that bobbin is bearing on the secondary mounting seat and driven by transmission device, is the parts that play sieving actoion in the roller picker.In traditional structure, the compass screen surface of roller picker all is horizontal, seal case also is whole the setting basically, this coarse coal that granularity is transfinited can not enter coal breaker easily, also make personnel's demolition, installation casing entirely when equipment is overhauled on the other hand, workload is big.In addition, the transmission of sieve bobbin is by Bevel Gear Transmission in the existing roller picker structure, and the fault rate height keeps in repair relatively difficulty, mainly is repairing or very inconvenience of replacing to damaged part, and the repair cycle is also very long.
The purpose of this utility model is to make improvements at the defective of traditional roller picker structure, provides a kind of screening effect good and be easy to the sloping formula roller picker of demolition, installation maintenances.
The main points of the improvement technical scheme that adopts are for achieving the above object: one, making the relative horizontal plane of compass screen surface of roller picker become skewed is domatic formula setting, and the coarse coal that the granularity of being more convenient for like this transfinites rolls in the coal breaker; Two, be nowel and top box two parts with seal case by roller picker sieve bobbin center subdivision, wherein top box is formed by adjoining preceding case, raising middle flask and rear cabinet three parts of suffering storing mutually again, and the demolition, installation workload when such structure can make maintenance greatly reduces.In addition, the kind of drive of sieve bobbin adopts the bushroller chain kind of drive in the utility model, has both reduced equipment failure rate, also makes the maintenance of transmission device work package and replacing become etc. simple.
Below with reference to accompanying drawing the utility model content is described further.
Fig. 1 is the front view of a specific embodiment structure of the utility model.
Fig. 2 is the top view of Fig. 1.
Referring to accompanying drawing, the operation principle of sloping formula roller picker described in the utility model, technical performance, installation dimension and appearance profile and traditional roller picker product are basic identical, also be to constitute by motor, reductor, big base 6, parts such as sieve bobbin 4, mounting seat 7 and seal case, but the compass screen surface in the utility model structure is skewed setting, the angle α value that forms between itself and horizontal plane satisfies 0 °＜α＜70 °, and the optimum value of α is about 15 °; The seal case that covers on the sieve bobbin 4 is nowel 5 and top box two parts from sieve bobbin center subdivision, wherein top box is divided into again and adjoins three sections that suffer storing mutually, case 2a, raising middle flask 2b and rear cabinet 2c promptly, the tail end of rear cabinet 2c is linked up mutually with coal import 3, and the head end of preceding case 2a is linked up mutually with coarse coal outlet 1 (also being the coal breaker inlet); The sieve bobbin is by the bushroller chain transmission.Number in the figure 8 is a sprocket wheel.
The utility model product and traditional product can integral body be replaced each other.
Claims (3)
1, a kind of sloping formula roller picker, constitute by motor, reductor, big base (6), sieve bobbin (4) and the parts such as seal case that cover on the sieve bobbin (4), the secondary mounting seat (7) that is bearing in sieve bobbin (4) goes up and is driven by transmission device, it is characterized in that
1.1, the relative horizontal plane of compass screen surface of roller picker becomes skewed setting;
1.2, seal case is nowel (5) and top box two parts by roller picker sieve bobbin center subdivision, wherein top box is formed by adjoining the preceding case (2a), raising middle flask (2b) and the rear cabinet (2c) that suffer storing mutually.
2, sloping formula roller picker as claimed in claim 1 is characterized in that the inclination alpha value that the relative horizontal plane of roller picker compass screen surface forms satisfies: 0 °＜α＜70 °.
3, sloping formula roller picker as claimed in claim 1 is characterized in that the kind of drive of sieving bobbin (4) adopts the bushroller chain kind of drive.
