Description

Technical Field

[0001] The utility model relates to the technical field of mineral resource smelting and cleaning equipment, in particular to an annular material distribution device for a feed pipe. Background Art

[0002] Submerged arc furnace is also called arc furnace or resistance furnace. It is mainly used for reducing smelting ore, carbonaceous reducing agent and solvent and other raw materials. The feed pipe of the submerged arc furnace is located at the top of the furnace body, and the feed is dropped by the weight of the charge. Due to the large size of the submerged arc furnace, the submerged arc furnace of most enterprises is generally embedded in the building of the factory, and the feed port of the submerged arc furnace is mostly set on the top floor of the building. The submerged arc furnace is large in size, and the furnace body is equipped with multiple feed pipes. When there are many feed pipes, the feed pipes are arranged in a ring.

[0003] The hopper moves along the track to feed the feed pipe in sequence; during the feeding period, the charge is discharged from the discharge port at the bottom of the hopper. The inlet of the feed pipe is covered with a filter. During the feeding process, after the charge contacts the filter, some of the charge collides with the filter, and the trajectory changes; there are also collisions between charges, and there is also the possibility of charge splashing, which ultimately results in not all of the charge entering the feed pipe. Some of the charge accumulates in the track and needs to be manually cleaned regularly. If it is not cleaned in time, the charge remains on the track path and accumulates to a certain height, affecting the operation of the hopper. After the charge in the hopper is used up, it returns to its original position for loading. Existing independent cleaning equipment is generally set on the material cart. The cleaning work is affected by the operating status of the equipment. Some independent cleaning equipment occupies the operating track in the non-cleaning state and needs to maintain a certain position relationship with the material cart. Even after cleaning, it needs to be operated, which increases the operating cost of the equipment. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a ring-shaped material distribution device for a feed pipe. While the cleaning purpose is achieved through the cleaning device, the device can be detached from the track and stopped in a non-cleaning state. After stopping, it will not occupy the track and affect the operation of the material car. The inner side of the track can be cleaned regularly to reduce the operating cost of the cleaning equipment.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A feeding pipe annular material distributing device comprises an annular side rail, a rotating ring, a gear ring, a fixed seat, a travel drive motor, a gear, a transfer drive motor, a cross frame, a top plate, a lifting frame, a material guide scraper and a lifting cylinder; the annular side rail is fixed under the track on which the material cart travels; the rotating ring is movably sleeved on the outer side of the annular side rail; the fixed seat is fixed to the side wall of the rotating ring; a travel drive motor is provided at the bottom of the fixed seat; a gear is connected to the driving end of the travel drive motor; a gear ring is fixed at the bottom of the annular side rail; the gear and the gear ring cooperate for transmission; a cross frame is rotatably provided on the surface of the fixed seat; the rotating shaft of the cross frame is connected to the driving end of the transfer drive motor; a top plate is fixed on the surface of the cross frame; a lifting frame is movably inserted on the top plate; a material guide scraper is fixed on the bottom of the lifting frame; a lifting cylinder is fixed on the surface of the top plate; the lifting cylinder is connected to the lifting frame to drive the lifting frame to move up and down.

[0007] Preferably, more than one rotating wheel is arranged and distributed on the ring body of the rotating ring; the rotating wheel moves along the slide groove of the annular side rail.

[0008] Preferably, the fixed seat is an inverted L structure, and a mounting groove is provided at the bottom of the fixed seat corresponding to the position of the gear ring, and the gear is arranged in the mounting groove; the travel drive motor is vertically fixed at the bottom of the fixed seat, and the driving end of the travel drive motor is inserted into the mounting groove and connected with the gear.

[0009] Preferably, the cross frame is provided with a movable groove at the position of the slide rod of the lifting frame; the slide rod passes through the top plate and the cross frame, and a notch is provided on one side of the movable groove corresponding to the material guide scraper. After the material guide scraper is raised to the highest position, it enters the notch and is higher than the track on which the material cart moves.

[0010] Preferably, a connecting plate is fixed between the slide bars of the lifting frame; and the telescopic end of the lifting cylinder is fixed to the connecting plate.

[0011] Preferably, both sides of the material guiding scraper are plate surface structures that are inclined to guide the flow toward the middle; and an overflow port is provided on the middle top surface of the material guiding scraper.

[0012] Beneficial effects of the utility model:

[0013] The device can control the position of the guide scraper. When cleaning is needed, the guide scraper enters the inner side of the track where the material cart is running. The furnace charge scattered on the inner side is concentrated to the middle through the guide scraper, so that the furnace charge enters the inner side of the feed pipe. After cleaning, the guide scraper is separated from the track where the material cart is running through the lifting cylinder. And it rotates to the outside of the track to avoid interference between the equipment and the material cart. It only needs to be cleaned regularly to avoid the cleaning equipment running with the material cart all the time, reducing the operating cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] As shown in the figure, the material cart moves along the track 13 on which it originally runs, and the feed pipe 14 is located on the inner side of the track 13. The main material spreading position is located on the inner side of the track 13 and around the mouth of the feed pipe 14. This part is the existing material cart feeding equipment and will not be described in detail. The main design is a ring-shaped material distribution device for the feed pipe 14, which runs based on the ring side rail 1, and the ring side rail 1 is fixed under the track 13 on which the material cart runs. The rotating ring 2 is movably sleeved on the outer side of the ring side rail 1; the ring body of the rotating ring 2 is arranged with more than one rotating wheel 2.1; the rotating wheel 2.1 runs along the slide groove 1.1 of the ring side rail 1. The fixed seat 4 is fixed to the side wall of the rotating ring 2 and moves synchronously with the rotating ring 2. A travel drive motor 5 is provided at the bottom of the fixed seat 4; the driving end of the travel drive motor 5 is connected to a gear 6; a gear ring 3 is fixed at the bottom of the ring side rail 1; the gear 6 and the gear ring 3 cooperate to transmit. Furthermore, the fixed seat 4 has an inverted L structure, and a mounting groove 4.1 is provided at the bottom of the fixed seat corresponding to the position of the gear ring 3, and the gear 6 is arranged in the mounting groove 4.1; the travel drive motor 5 is vertically fixed at the bottom of the fixed seat 4, and the driving end of the travel drive motor 5 is inserted into the mounting groove 4.1 and connected with the gear 6.

[0023] As shown in the figure, a horizontal frame 8 is rotatably provided on the surface of the fixed seat 4; the rotating shaft of the horizontal frame 8 is connected to the driving end of the transfer drive motor 7, and the transfer drive motor 7 controls the rotation of the horizontal frame 8, and the rotation of the horizontal frame 8 can be separated from the position above the track 13 on which the material car moves. A top plate 9 is fixed on the surface of the horizontal frame 8; a lifting frame 10 is movably inserted on the top plate 9; a material guide scraper 11 is fixed to the bottom of the lifting frame 10; the two sides of the material guide scraper 11 are plate structures that are inclined to guide the flow toward the middle, so as to facilitate the gathering of the furnace charge to the middle. An overflow port is provided on the middle top surface of the material guide scraper 11. When too much furnace charge is gathered, in order not to affect the operation and movement of the equipment, the furnace charge is discharged from the overflow port. The discharged furnace charge needs to be cleaned up by the cleaning equipment for multiple rounds to complete the cleaning. A lifting cylinder 12 is fixed on the surface of the top plate 9; the lifting cylinder 12 is connected to the lifting frame 10 to drive the lifting frame 10 to move up and down. The horizontal frame 8 is provided with a movable groove 8.1 at the position of the slide bar 10.1 of the lifting frame 10; the slide bar 10.1 penetrates the top plate 9 and the horizontal frame 8, and a notch 8.2 is provided on one side of the movable groove 8.1 corresponding to the material guide scraper 11. After the material guide scraper 11 is raised to the highest position, it enters the notch 8.2 and is higher than the track 13 for the material car to move. Only when it is higher than the track 13 can the transfer drive motor 7 be controlled to work. A connecting plate 10.2 is fixed between the slide bars 10.1 of the lifting frame 10; the telescopic end of the lifting cylinder 12 is fixed to the connecting plate 10.2.

If the fixing method is not separately introduced above, it is welded or screwed using the common technical means of technical personnel in the industry.

[0024] Here’s how it works:

[0025] First, the transfer drive motor 7 is controlled to work, so that the cross frame 8 moves to the top of the track 13 where the material cart moves, and then the lifting cylinder 12 is controlled to extend, so that the lifting frame 10 descends into the track 13 where the material cart moves, and the travel drive motor 5 starts to work, so that the whole equipment starts to move along the annular side track 1, and the material guide scraper 11 passes through a feed pipe 14 and scrapes the furnace charge splashed on the inner side of the track 13 to the feed pipe 14 position. When the amount of splashed furnace charge is low, one circle of movement is completed to complete the cleaning work. When the amount of splashed furnace charge is large, multiple circles of operation are required. After the cleaning is completed, the lifting frame 10 is reset, and the transfer drive motor 7 controls the cross frame 8 to rotate and move outward.
