Description

Slag crushing manipulator suitable for power plant boiler

Technical Field

The utility model relates to the technical field of slag crushing devices, in particular to a slag crushing manipulator suitable for a power plant boiler.

Background

In the running process of the power plant boiler, because the ash fusion point of coal in the combustion of the coal is lower, the coal ash is melted and cohered and accumulated on a grate. If the blast and the induced draft are too large in operation, the intensified combustion is carried out, and when the furnace temperature exceeds the bonding temperature of the coal ash, high-temperature coking can be formed. If the air distribution is improper, the coal is not completely combusted, and coking can also be formed. If the coke making and slag removal are not in time, the ash slag and the red fire are mixed together, so that the formation of coke slag is aggravated.

The existing decoking means are generally manually operated, and workers clean the coke residue by using iron rods to mechanically collide from a fire observation hole of a hearth, but the method is time-consuming and labor-consuming, low in safety coefficient and poor in working environment.

Detailed Description

Examples

All of the features disclosed in this specification, or all of the steps in a method or process disclosed, may be combined in any combination, except for mutually exclusive features and/or steps.

The present utility model will be described in detail with reference to fig. 1 and 2.

The slag crushing manipulator suitable for the power plant boiler comprises a shell 1, wherein a motor 2 is arranged in the shell 1, and the motor 2 is a 1000W 24v direct current motor; the output shaft of the motor 2 is connected with a pinion 9, the pinion 9 is meshed with a large gear 3, the large gear 3 is connected with a connecting rod 5, and the connecting rod 5 is T-shaped and hollow; the shell 1 and the connecting rod 5 are aluminum alloy pipes with certain wall thickness, so that the service life of the device is prolonged; one end of the connecting rod 5 far away from the motor 2 is rotationally connected with a plurality of L-shaped drill bit bodies 7, each drill bit body 7 comprises a plurality of drill bits 4, each drill bit 4 is arranged at the end part and the inner side of each drill bit body 7, a controller 11 is arranged inside the connecting rod 5, and the controller 11 is limited and fixed through a circular ring, so that the suspension of the controller 11 is avoided.

The electromagnet 10 is installed at the bottom of the shell 1, the controller 11 is driven to move through the attraction of the electromagnet 10, a notch is formed in the controller 11, and the end part of the drill bit body 7 can be clamped, so that the drill bit body 7 is driven to rotate, and the drill bit body 7 is closed and expanded. The controller 11 is an iron rod, the top is in a dry shape, and the bottom penetrates through the large gear 3 and is fixedly connected with a metal block.

Before the drill bit 4 extends above the fire grates, the electromagnet 10 is electrified, the controller 11 moves downwards due to the attraction force of the electromagnet 10 to pull the drill bit main body 7 to be closed towards the middle, and the closed device can pass through gaps among the fire grates; after the drill bit 4 stretches to the grate top, outage to electro-magnet 10, because the focus of drill bit main part 7 is upper portion and the outside of partially, and drill bit main part 7 is dispersed all around because of gravity effect, drives the upwards movement of controller 11, then starts motor 2, rotates through the gear train and drives connecting rod 5 rotation, and drill bit main part 7 is dispersed more under the effect of centrifugal force, and area of contact with cinder is bigger, and work efficiency is higher. The drill bit 4 rotates to beat and clean cinder adhered to the boiler grate, the controller 11 is moved downwards by the suction force of the electromagnet 10 after cleaning, the drill bit body 7 is driven to fold towards the middle again, and finally the device is taken out.

The arrow in the figure indicates that the controller 11 is attracted downward by the electromagnet 10, and the bit body 7 is closed toward the middle.

The drill bit 4 is a six-edge drill bit, the multi-layer cutting surface is adopted, and the coal briquette breaking speed is higher; and the high-temperature-resistant metal material is used for manufacturing the high-temperature-resistant metal material, so that the mechanical strength is not reduced or melted in a high-temperature environment after long-term operation.

The handle 8 is arranged on the shell 1, so that a worker can conveniently hold the device to perform slag removal operation.

A bearing 6 is arranged between the connecting rod 5 and the shell 1, so that friction is reduced, and the motor 2 is smoother when driving the connecting rod 5 to rotate through a gear set.

The worker holds the handle 8 with both hands, lifts upwards and stretches the drill bit 4 to the grate top, and the drill bit main body 7 spreads all around because of gravity, starts motor 2, and the drill bit 4 rotatory beats the coal cinder, beats and finishes earlier through electro-magnet 10 control 11, makes the drill bit main body 7 fold to the centre, then withdraws the device.
