Description

Raw coal bunker clearing and anti-blocking machine

technical field

The utility model relates to the field of raw coal bunker clearing and blocking equipment, in particular to a raw coal bunker cleaning and anti-blocking machine.

Background technique

During the operation of the thermal power generation unit, the raw coal bunker that supplies coal to the generator unit often occurs coal blockage and coal failure, especially in the rainy season, winter, coal quality changes and different fuels. Sometimes one unit 3 ~ When 4 raw coal bunkers run out of coal at the same time, the unit is forced to shed load, put oil into the plant for stable combustion, and even extinguish fires.

At present, the scraper type raw coal bunker cleaning and anti-blocking machine used in China is composed of an upper bin body, a lower bin body, and a rolling structure between the upper and lower bin bodies. The rolling structure includes a lower support body, a rolling body and a gear ring. The rolling body is installed on the top, the gear ring is set on the rolling body, and the scraper is arranged inside the warehouse body. The anti-blocking machine with this structure, when the scraper is working, can only push the coal to move in one direction. When the coal blocking resistance is particularly large, the scraper can only push the coal more and more solidly, and cannot play the role of clearing the blockage. , In addition, because the lower end of the scraper is not connected to the cylinder wall, the effect of dredging and clearing the blockage is not very good.

Utility model content

In order to overcome the problems existing in the prior art, the utility model provides a scraper with simple structure, low cost, double-sided scraping, and a good effect of cleaning and preventing raw coal bunkers.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a raw coal bunker blockage removal and anti-blocking machine, including an upper cylinder, a lower cylinder, a rotating cylinder, a slewing support and an integral frame support, the upper cylinder, The lower cylinder, the rotating cylinder and the slewing support are all arranged on the overall frame support, the rotating cylinder is arranged between the upper cylinder and the lower cylinder, and the outer wall of the middle part of the rotating cylinder is provided with a gear plate, so The gear plate is connected with a slewing support that cooperates with it through a sliding connection, and the gear plate is also connected to a motor through a reducer, and also includes an integrally formed scraper, the upper end of the scraper is fixedly connected to the inner wall of the lower end of the upper cylinder, and the The lower end of the scraper is fixedly connected to the inner wall of the upper end of the lower cylinder, the shape of the scraper body matches the inner wall of the rotating cylinder, the scraper and the inner wall of the rotating cylinder form a certain angle, and the scraper and the inner wall of the rotating cylinder There is a certain gap between them.

A sensor is arranged on the inner wall of the lower cylindrical body, and the sensor is connected with a control system, and the control system is also connected with the motor.

The control system adopts PLC control system.

The beneficial positive effects of the utility model are: the scraper of the utility model is formed by forging once, the structure is simple and reasonable, time and material are saved, the cost is low, and the load capacity is strong, it is not easy to bend and break, the service life is long, safe and reliable, light in weight, By being fixed on the upper and lower cylinders, it is easy to replace, and reduces the load of the driving device, and has a good anti-blocking and clearing effect; in addition, the two sides of the scraper work separately, which makes it easier to remove the material adhered to the inner wall of the cylinder, making it easier for the material and the warehouse wall Separation increases the fluidity of materials and enhances the effect of blockage prevention and blockage removal.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

Referring to Fig. 1 and Fig. 2, a raw coal bunker cleaning and anti-blocking machine of the utility model includes an upper cylinder body 1, a lower cylinder body 4, a rotating cylinder body 2, a slewing support 8 and an integral frame support 9, the upper cylinder body 1. The lower cylinder 4, the rotating cylinder 2 and the slewing support 8 are all arranged on the overall frame support 9, the rotating cylinder 2 is arranged between the upper cylinder 1 and the lower cylinder 4, and the rotating cylinder 2 The outer wall of the middle part is provided with a gear plate 7, said gear plate 7 is connected with a slewing support 8 matched with it by sliding, said gear plate 7 is also connected with a motor through a reducer 6, and also includes an integrally formed scraper 3, so The upper end of the scraper 3 is fixedly connected to the inner wall of the lower end of the upper cylinder 1, the lower end of the scraper 3 is fixedly connected to the inner wall of the upper end of the lower cylinder 4, and the shape of the blade body of the scraper 3 matches the inner wall of the rotating cylinder 2, The scraper 3 forms a certain angle with the inner wall of the rotating cylinder 2 so that it has a downward thrust effect, and a certain gap is left between the scraper 3 and the inner wall of the rotating cylinder 2 .

A sensor 5 is arranged on the inner wall of the lower cylinder 4, and the sensor 5 is connected with a control system, and the control system is also connected with the motor.

The control system adopts PLC control system.

When working, the motor, reducer 6, and slewing support 8 form a driving device. When the driving device drives the rotating cylinder 2 to rotate forward along the central axis, the blade surface of the scraper 3 plays the role of scraping, cutting, stirring, and pushing the material to fall; the driving device drives When the rotating cylinder 2 reverses along the central axis, the blunt surface of the scraper 3 scrapes, cuts, stirs and pushes the material again, and the two sides of the scraper 3 continuously scrape, cut, and push the materials in the bin and on the bin wall. Stirring and propulsion make the feeding in the material bin smooth, and achieve the purpose of preventing and clearing the blockage.
