Description

Technical Field

[0001] The utility model relates to the technical field of furnace feeding, in particular to an adjustable feeding chute structure of a tower furnace. Background Art

[0002] Some medium frequency tower melting furnaces need to use automatic feeding mechanisms to periodically replenish smelting raw materials. Due to the presence of the feeding trolley and the dust cover, the feeding trolley cannot directly add the smelting raw materials into the furnace, so an intermediate transition chute feeding mechanism needs to be installed.

[0003] The traditional arrangement is to add a fixed chute. Since the chute is located above the furnace mouth, the smelting temperature in the furnace is relatively high, and the heat radiation to the chute is relatively serious, which makes the chute easily damaged, thereby affecting the feeding efficiency. Summary of the invention

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an adjustable feeding chute structure of a tower furnace, which can cooperate with a feeding trolley to realize the movement of the chute, avoid being exposed to the heat radiation of the furnace for a long time, and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable feeding chute structure of a tower furnace, comprising a feeding trolley and a fixed frame, the feeding trolley can move up and down along the fixed frame, a tower furnace is arranged on one side of the fixed frame, two inclined tracks are symmetrically arranged on one side of the fixed frame, and a chute moving along its length direction is arranged at the upper end of the track.

[0006] As a preferred technical solution of the utility model, a support frame is slidably connected in the track, and the chute is fixedly connected to the support frame.

[0007] As a preferred technical solution of the utility model, a driving mechanism for controlling the movement of the support frame is provided at the lower end of the support frame.

[0008] As a preferred technical solution of the utility model, the driving mechanism includes a motor reducer and a driving gear, the motor reducer is arranged below the support frame, the driving gear is connected to the output shaft of the motor reducer, a rack is arranged at the lower end of the support frame, and the driving gear is meshed with the rack.

[0009] Compared with the prior art, the beneficial effects of the utility model are: the adjustable feeding chute of the tower furnace is reasonably designed and easy to operate. By setting the chute to be movable, the chute is moved to the top of the tower furnace for guiding materials when loading, and the chute is retracted when the feeding trolley is reset to avoid the high temperature area of ​​the furnace mouth, thereby preventing the chute from being damaged by heat radiation for a long time and extending the service life of the chute.

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments (for the convenience of description and understanding, the following is a schematic diagram of the present invention). Figure 1 Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0014] See also Figure 1-2 The utility model provides a technical solution: an adjustable feeding chute structure of a tower furnace, comprising a feeding trolley 1 and a fixed frame 9, the fixed frame 9 is provided with a chain lifting mechanism, the feeding trolley 1 can move up and down along the fixed frame 9, a tower furnace 8 is provided on one side of the fixed frame 9, and two inclined tracks 7 are symmetrically provided on one side of the fixed frame 9, a support frame 3 is slidably connected in the track 7, the chute 2 is fixedly connected to the support frame 3, and a driving mechanism for controlling its movement is provided at the lower end of the support frame 3. Preferably, the driving mechanism comprises a motor reducer 4 and a driving gear 5, the motor reducer 4 is arranged below the support frame 3, the driving gear 5 is connected to the output shaft of the motor reducer 4, a rack 6 is arranged at the lower end of the support frame 3, the driving gear 5 is meshed with the rack 6, and the driving gear 5 is driven to rotate by the motor reducer 4, and then the rack 6 and the support frame 3 are driven to move together under the meshing action of the teeth, thereby driving the chute 2 to move along the inclined direction of the track 7.

[0015] During use: after the loading trolley 1 brings the smelting raw materials to the fixed frame 9, the motor reducer 4 drives the driving gear 5 to rotate, and then drives the rack 6 and the support frame 3 to move, so that the chute 2 moves to the furnace mouth position, and the smelting raw materials enter the tower furnace 8 through the chute 2; when the loading trolley 1 is reset to add materials, the chute 2 moves back to avoid the furnace mouth and waits for the next loading.

[0016] The utility model provides a movable chute 2 to cooperate with a feeding trolley 1 to add materials into the tower furnace, so that the chute 2 avoids the high temperature area of ​​the furnace mouth when not guiding materials, thereby extending the service life of the chute 2, reducing the number of replacements, and improving the feeding efficiency.

[0017] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
