Description

Technical Field

[0001] The utility model relates to the technical field of mineral smelting environment cleaning equipment, in particular to a furnace charge anti-pileup pusher. Background Art

[0002] Submerged arc furnace is also called arc furnace or resistance furnace. It is mainly used for reducing and smelting raw materials such as ore, carbonaceous reducing agent and solvent. The feed pipe of the submerged arc furnace is located at the top of the furnace body, and the feed is completed by the weight of the charge. Since the submerged arc furnace body is large, there are multiple feed pipes on the top of the furnace body for feeding. The traditional feeding method is to feed through a conveyor belt or a distributor. The track is arranged in a ring above the feed port, and the feed pipes are distributed on the inside of the track. The feed car moves along the track to the feed port in turn to feed the charge. During the feeding period, the charge is directly discharged from the discharge port at the bottom of the feed car.

[0003] During the unloading process, there is a large height difference between the discharge port on the inner side of the track and the distributor, and the mouth of the feed pipe is sealed with a filter. After the charge directly hits the filter, some of the charge will splash. If the splashed charge is not handled, the charge will accumulate too much in the track, affecting the normal operation of the charge car; the traditional cleaning method is mostly manual cleaning, mainly because the charge is irregular in shape, and some of the charge easily blocks the mesh of the filter, causing the charge to accumulate above the filter. Therefore, before the splashed charge is put into the filter, the charge blocked by the filter needs to be handled first, otherwise the charge will still accumulate at the filter position. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a charge anti-pile-up pusher, by which the charge on the filter can be vibrated so that the charge can continuously adjust its angle until it falls through the filter, and all the charge splashed in the track is concentrated on the filter.

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

[0006] A material pusher for preventing furnace charge accumulation comprises a movable bottom plate, walking wheels, a ring rail, a support frame, a vibrating rod, a top plate, a travel rod, a vibration spring, a vibration motor and a material collecting seat; a walking wheel is movably provided under the movable bottom plate; the walking wheel moves along the ring rail; a support frame is fixed to the middle part of the surface of the movable bottom plate; travel rods are movably inserted at both ends of the support frame; the top of the travel rod is fixedly connected to the top plate; a vibration spring is sleeved on the rod body of the travel rod; a vibration motor is fixed to the top plate; one or more vibrating rods are arranged at the bottom of the top plate corresponding to the filter screen; a material collecting seat is fixed to the end position of the movable bottom plate, and the material collecting seat moves along the inner side of the track.

[0007] Preferably, the support frame has a plate surface with through holes at positions corresponding to the vibration rods; the movable bottom plate has a surface with movable holes having the same number as the vibration rods, and the vibration rods move up and down along the through holes of the movable bottom plate.

[0008] Preferably, the width of the material collecting seat is less than or equal to the width between the rails; and the material collecting seat is a semicircular arc structure.

[0009] Preferably, the walking wheel is driven by a driving motor.

[0010] Preferably, a guide wheel is provided below the movable base plate, and the guide wheel limits the moving path of the movable base plate along the inner wall of the track.

[0011] Beneficial effects of the utility model:

[0012] After the distributor completes the distribution work, the device runs independently along the circular track; the filter screen can be knocked by the vibrating rod to make the angle of the charge on the filter screen constantly change, so as to avoid the charge close to the filter mesh being stuck in the filter position due to the poor discharge process of the charge; the gathering seat can push the charge on the inner side of the track to gather to the middle position, and when the charge passes through the filter screen position, it enters the feed port.

DETAILED DESCRIPTION

[0018] like Figure 1-3As shown, the inner side of the track is the feed port on the top of the furnace body, and a blocking filter screen 13 is provided on the feed port; the feed ports are arranged in a ring. A charge stacking prevention pusher is designed, and a travel wheel 2 is movably provided under the movable bottom plate 1; the travel wheel 2 is driven by a driving motor 11, and the travel wheel 2 moves along the ring track 3; further, a guide wheel 12 is provided under the movable bottom plate 1, and the guide wheel 12 limits the moving path of the movable bottom plate 1 along the inner wall of the track. A support frame 4 is fixed to the middle of the surface of the movable bottom plate 1; travel rods 7 are movably inserted at both ends of the support frame 4; the top of the travel rod 7 is fixedly connected to the top plate 6; the rod body of the travel rod 7 is provided with a vibration spring 8; a vibration motor 9 is fixed to the top plate 6, and the vibration motor 9 is a vertical vibration motor that vibrates in the longitudinal direction. At the bottom of the top plate 6, one or more vibrating rods 5 are arranged corresponding to the filter screen 13; the plate surface of the support frame 4 is provided with a through hole 4.1 at the position corresponding to the vibrating rod 5, and the through hole 4.1 can pass through all the vibrating rods 5. According to the current rectangular arrangement of the vibrating rods 5, the through hole 4.1 is a rectangular hole. A material collection seat 10 is fixed at the end position of the movable bottom plate 1, and the material collection seat 10 moves along the inner side of the track. It should be noted that the width of the material collection seat 10 is less than or equal to the width between the tracks to ensure that the material collection seat 10 can enter; the material collection seat 10 is a semicircular arc structure. During the scraping process of the charge, the charge will gather toward the middle along the arc surface. The surface of the movable bottom plate 1 is provided with movable holes 1.1 that are the same in number as the vibrating rods 5, and the vibrating rods 5 move up and down along the movable holes 1.1 of the movable bottom plate 1. If the fixing method is not separately introduced above, it is welded or threaded fastened using the common technical means of technicians in the industry.

[0019] Here’s how it works:

[0020] The device controls the travel wheel 2 to move along the circular track 3 through the driving motor 11. During the movement, the furnace charge splashed on the inner side of the track is gathered and pushed toward the middle through the collecting seat 10. When passing through the feed port at the position of the filter screen 13, the furnace charge falls onto the filter screen 13. The furnace charge enters the feed port to complete the cleaning work. In order to prevent the filter screen 13 from being blocked, the vibrating rod 5 vibrates and knocks the filter screen 13 through the vibration motor 9 to make the material discharge smooth.
