Referring to fig. 1 and fig. 2, a heating furnace slag removal device 100 is provided in the present embodiment, and the heating furnace slag removal device 100 provided in the present embodiment can be applied to slag removal operation of a heating furnace 40. The slag in the heating furnace 40 directly slides into the slag runner through the conveying groove 10 by utilizing the gravity of the slag, the distance for manually transferring the slag by operators is shortened, the labor force is saved for the operators, the slag removing working hours are shortened, and the slag removing efficiency is improved.

In the embodiment of the application, the heating furnace slag removal device 100 is applied to a heating furnace 40, the heating furnace 40 includes a furnace body 41, the furnace body 41 is provided with a furnace door 42 and a grid plate 43, the grid plate 43 is provided with a discharge port 44, the heating furnace slag removal device 100 includes a transport tank 10, one end of the transport tank 10 is connected to the furnace door 42, the other end of the transport tank 10 penetrates through the discharge port 44 and extends to a slag runner, the transport tank 10 is arranged in a downward inclination mode relative to the furnace door 42, slag in the furnace body 41 enters the transport tank 10 through the furnace door 42, and the slag can slide into the slag runner along the transport tank 10 under the action of self gravity. The conveying trough 10 is directly communicated with the furnace door 42 and the slag runner, so that the distance for manually transporting the slag by operators is greatly shortened, and the cleaning efficiency of the slag is improved while manpower is saved.

The inclination angle of the transportation groove 10 and the ground is 35-40 degrees. Too large inclination angle of transport trough 10 can lead to the acceleration of slag great, and the slag gliding is too fast under self action of gravity, easily dashes out transport trough 10, also easily produces too big dust in the collision process again. And too small inclination angle of the transportation groove 10 can cause too low acceleration of the slag, the downward sliding speed of the slag under the action of self gravity is too low, and the slag is easy to mutually pile up and block the transportation groove 10 when the amount of the slag is large. When the inclination angle of the transport groove 10 and the ground is 35-40 degrees, the sliding speed of the slag is moderate, the slag can quickly slide into the slag runner, the slag is prevented from being accumulated in the transport groove 10, and a large amount of dust cannot be lifted.

The transportation groove 10 comprises a feeding section 11, a buffer section 12 and a discharging section 13, wherein the feeding section 11, the buffer section 12 and the discharging section 13 are sequentially connected, the feeding section 11 is connected to the furnace door 42, the discharging section 13 extends to the slag runner, the feeding section 11 and the discharging section 13 are arranged at an included angle, the buffer section 12 is arranged in a bending mode, and the buffer section 12 changes the falling direction of slag and reduces the falling speed. Because the heating furnace 40 has a certain height difference with the ground, if the transport tank 10 is a straight cylinder type, the speed of the slag when the slag reaches the slag runner is too fast under the acceleration of the self gravity of the slag, and dust is easily excited. After the slag is accelerated for the first time through the feeding section 11, the running direction of the slag is changed at the buffer section 12 which is arranged in a bending mode, the buffer function is achieved, the speed of the slag coming out of the feeding section 11 is weakened, and the slag slides downwards again in the new direction of the discharging section 13 due to the action of self gravity after passing through the buffer section 12. In the process, the bending arrangement of the buffer section 12 can effectively weaken dust generated by slag collision. The included angle between the feeding section 11 and the discharging section 13 is larger than 100 degrees, and the initial speed of the slag towards the discharging section 13 is also provided after the direction of the slag is changed in the buffer section 12, so that the slag is prevented from being accumulated in the buffer section 12.

The end connection of ejection of compact section 13 has material blocking member 20, forms feed opening 23 between material blocking member 20 and the tip of ejection of compact section 13, and material blocking member 20 blocks the slag and dashes out transport tank 10 because of inertia, makes the slag get into the slag runner through feed opening 23. The speed of the slag at the end of the discharging section 13 is high, and the slag is easy to flush out of a slag runner, so that the collection of the slag is influenced. Meanwhile, the head of part of slag blocks is large, the slag blocks directly impact the slag runner to influence the next discharge of the slag runner, the slag can be broken by impacting the material blocking part 20, and then the slag blocks accurately fall into the slag runner through the discharging opening 23, so that the overall reverse transportation efficiency of the slag runner is improved.

The material blocking part 20 comprises a baffle plate 21 and a connecting piece 22, and two sides of the baffle plate 21 are respectively connected to the end part of the discharging section 13 through the connecting piece 22. The connecting piece 22 plays a fixed role, the baffle 21 and the end part of the discharging section 13 naturally form a discharging opening 23, and the two sides of the baffle 21 are fixed to enable the baffle 21 to be stressed uniformly, so that the firmness is stronger.

One side of the baffle 21 facing the discharging section 13 is provided with a crushed stone structure for crushing the fallen large slag. When the slag rushes to the broken stone structure, the impact force generated by the speed can effectively break the slag, so that the subsequent slag is convenient to discharge.

The gravel structure is a plurality of bosses which are distributed unevenly and the bosses are pyramid-shaped. The pyramid-shaped boss is firm in structure, is more uniform in stress, forms a convex tip, and can effectively crush the slag.

The ratio of the length of ejection of compact section 13 and the length of feeding section 11 is greater than 2, and the setting of feeding section 11 and ejection of compact section 13 plays and weakens the last speed effect of slag, but the slag that ejection of compact section 13 came out needs certain speed, and the slag just can be broken when assaulting material stopping member 20, and the ratio of the length of ejection of compact section 13 and the length of feeding section 11 is greater than the length of 2 assurance ejection of compact sections 13 that can be fine, has guaranteed promptly that the last speed of slag can not be too little.

Referring to fig. 2 to 4, the slag removal device 100 further includes a grille cover 30, and the grille cover 30 is used for sealing the discharge hole 44. The grid plate 43 of the heating furnace 40 is used for an operator to stand to check the operation condition of the heating furnace 40, and the operator often walks on the grid plate 43. The grill cover 30 seals the post outlet 44 to prevent an operator from stepping into the outlet 44 and causing injury.

The grid interval of the grid cover plate 30 is smaller than that of the grid plate 43, so that the structure of the grid cover plate 30 is reinforced, a distinguishing effect is achieved, and operators can distinguish different areas conveniently.

The transportation groove 10 is one of a U-shaped groove, a V-shaped groove or a trapezoid groove, and can play a good role in guiding slag.

In conclusion, the slag of the heating furnace 40 directly slides down from the conveying groove 10 through the furnace door 42, so that the distance for carrying the slag by operators is greatly shortened, and the slag cleaning efficiency is improved. And the slag is only required to be placed into the conveying groove 10 connected with the furnace door 42 by an operator, and slides to the slag runner under the action of the gravity of the operator, so that the labor of the operator is greatly saved. The operator only needs to stand in the heating furnace 40, does not need to go out of the heating furnace 40, reduces the falling risk of the operator, reduces the dust generated in the gliding process of the slag in the transportation groove 10, and effectively protects the breathing safety of the operator. The design of the conveying trough 10 improves the construction safety of operators, effectively saves the strength of the operators, shortens the working hours of slag removal and improves the slag removal efficiency.
