Description

Technical Field

[0001] The utility model relates to the field of feeding equipment for roller smelting, in particular to a feeding device for rare earth roller smelting. Background Art

[0002] At present, in the smelting production process of rare earth rollers, the raw materials need to be transported to the top of the smelting furnace and put into the smelting furnace for processing, so a tool is needed to transport them to the top of the smelting furnace. At present, the common practice is to use a small cart, load the raw materials on the cart, push them to the smelting furnace, and then manually dump the raw materials in the cart into the furnace. This method has low feeding efficiency and high labor intensity.

[0003] Announcement No. CN211903753U proposes a feeding device for rolling mill smelting. The device enables the unloading bin to be adjusted according to the height of the smelting furnace through the cooperation of the main fixed column, the auxiliary fixed column and the screw, thereby increasing the application range of the equipment. The setting of the side column makes the equipment more stable during the rising process of the unloading bin. Through the active wheel and the connecting telescopic control unloading baffle, and in conjunction with the telescopic rod and the spring, the user can effectively control the unloading of the unloading bin, thereby ensuring the working efficiency of the rolling mill smelting; however, in the process of unloading into the smelting furnace, the person is close to the smelting furnace, and the temperature of the smelting furnace itself is very high, which poses a safety hazard.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0029] like Figures 1 to 3 As shown, a rare earth roller smelting feeding device includes a self-propelled trolley (the self-propelled trolley is one of the AGV trolley 1 or the electric flat car. The AGV trolley automatically transports items to a designated location through special landmark navigation. The most common guidance methods are magnetic strip guidance, laser guidance, RFID guidance, etc., which belong to the existing technology and do not need improvement). A vertical lifting component is arranged on the self-propelled trolley, and a horizontal moving component is arranged on the vertical lifting component. The horizontal moving component is connected to a U-shaped frame 23 and a barrel 3 is arranged in the U-shaped frame 23. A feed hopper 31 and a discharge port 32 are arranged on the barrel 3, and a solenoid valve is arranged on the discharge port 32. The solenoid valve is shown in the figure without a number.

[0030] Further refinement of the embodiment of the present utility model is as follows: Figure 1 As shown, the vertical lifting assembly includes a first hydraulic cylinder 11, a first telescopic rod 12 and a mounting platform 13. The self-propelled trolley is provided with the first hydraulic cylinder 11 and the first telescopic rod 12, and the first hydraulic cylinder 11 and the first telescopic rod 12 are both connected to the mounting platform 13; the horizontal moving assembly includes a second hydraulic cylinder 21 and a second telescopic rod 22. The mounting platform 13 is provided with the second hydraulic cylinder 21 and the second telescopic rod 22, and the second hydraulic cylinder 21 and the second telescopic rod 22 are both connected to the U-shaped frame 23.

[0031] Further optimization of the embodiment of the utility model is as follows: Figure 2 and Figure 3 As shown, a fixed platform 24 is symmetrically arranged on the U-shaped frame 23, a weighing device 25 is arranged on the fixed platform 24, an inserting tube 26 is arranged on the weighing device 25, and an inserting column 33 corresponding to the inserting tube 26 is arranged on the barrel 3, and the inserting column 33 cooperates with the inserting tube 26;

[0032] In a further refinement of the above embodiment, a magnet is provided at the bottom of the insert cylinder 26, and the insert column 33 is made of stainless steel. The magnet is not shown in the figure. The magnetic adsorption between the magnet and the insert column 33 can make the barrel 3 firmly installed on the U-shaped frame 23, so that no shaking occurs during the lifting process.

[0033] It should be noted that the self-propelled vehicle, the first hydraulic cylinder 11, the second hydraulic cylinder 21 and the solenoid valve are all electrically connected to the controller, which is not shown in the figure.

[0034] The workflow of this utility model:

[0035] First, the controller controls the self-propelled trolley to move to one side of the smelting furnace and stop. The running route of the self-propelled trolley is pre-set in the controller, so there is no need to manually push and transfer the barrel 3 to the smelting furnace, and the labor intensity and safety hazards are reduced. When the self-propelled trolley stops, the barrel 3 can be raised by the vertical lifting component. When the barrel 3 rises to a height that does not affect the horizontal movement, the horizontal moving component works to make the discharge port 32 of the barrel 3 accurately move to the top of the entrance of the smelting furnace. Then the controller controls the solenoid valve to open to realize the automatic feeding of the material in the barrel 3.

[0036] In addition, the barrel 3 and the U-shaped frame 23 are movably connected through the insert 26 and the insert column 33. When the insert 26 enters the insert column 33, it will contact the magnet to limit the position of the barrel 3. A fixed mass of rare earth roller smelting materials are stored in the barrel 3 in advance. At this time, the weighing device 25 feeds back the value determined by the controller. When feeding is required, the solenoid valve is opened. As the material is fed in, the weighing value of the weighing device 25 will decrease. When it drops to the preset residual weight (i.e., total weight-feeding weight=residual weight), the controller controls the solenoid valve to close, so that quantitative feeding can be achieved, and the use effect of the device is better and more accurate.

[0037] Compared with the existing technology, this device does not need to manually push the transfer cart to the side of the smelting furnace to complete the feeding process, so the labor intensity is reduced. At the same time, the safety of the feeding process is improved. Personnel do not need to be close to the heat source. In addition, quantitative feeding can be achieved, so that the subsequent smelting effect of the rare earth roller is better.

[0038] In some embodiments, Figure 1 and Figure 2As shown, an auxiliary mounting plate 41 is movably and symmetrically arranged on the U-shaped frame 23, and a clamping assembly is arranged on the auxiliary mounting plate 41;

[0039] The clamping assembly includes a cylinder 42 and a clamping plate 43. The cylinder 42 is symmetrically arranged on the auxiliary mounting plate 41. The cylinder 42 is connected to the clamping plates 43 that are arranged opposite to each other. To optimize the solution, the clamping plates 43 are provided with anti-skid and wear-resistant pads, which are specifically rubber pads. The anti-skid and wear-resistant pads are not shown in the figure. This embodiment can transport some large roller smelting materials through the clamping assembly, and thus the functionality of the feeding device is better.

[0040] In other embodiments, a counterweight box is provided on the self-propelled trolley, and a plurality of counterweights are provided inside the counterweight box, which is not shown in the figure; this embodiment can ensure the balance of the entire self-propelled trolley during the horizontal movement of the barrel 3 approaching the smelting furnace through the counterweight box and the counterweights.

[0041] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the protection required by the utility model.
