Description

Technical Field

[0001] The utility model relates to a material feeding and conveying device for a mixer, belonging to the field of mixed material processing devices. Background Art

[0002] To mix rare earth materials, first pour the materials into the mixer manually, then pack and weigh them manually after mixing, pack them into standard packages, and then use a forklift to deliver them to each furnace for use. The whole process is manual operation, and there are cases of wrong materials and weight discrepancies. The operation efficiency is low and the labor intensity is high. Rare earth materials produce a lot of dust during the mixing process, which can easily cause harm to the body. Because the viscosity of rare earth materials is different from that of other powders, it is easy to cause blockage or "bridging" of the pipeline during the material transportation process. Therefore, how to realize the loading and transportation of rare earth materials is a difficult problem that this patent needs to solve.

[0003] Chinese patent CN208373013U is an automatic raw material feeding system for a mixer, "an automatic raw material feeding system for a mixer, including a plurality of conveying devices controlled by a computer, the conveying devices feed the measured materials into the mixer, the improved design of the entire device system improves the level of production automation, while reducing the number of personnel on site and reducing the overall operating costs of the enterprise". The disadvantages of this patent are that it does not solve how the front-end incoming materials are fed into the mixer and how to achieve accurate measurement. Utility Model Content

[0029] As attached Figure 1 , 2 As shown, a feeding and conveying device for a mixer includes a mixing module and a feeding module;

[0030] The mixing module comprises a raw material bin 1, a dust collector 2, a feeding port 3, a mixing conveying pipeline 4, a vacuum feeder 5, a mixing recoiler 6, a conical mixer 7, a mixing Roots blower 10, and a vacuum pipeline 11; a dust collector (2) and a feeding port (3) are arranged above the raw material bin (1); the raw material bin 1 is connected to the vacuum feeder 5 through the mixing conveying pipeline 4; a mixing recoiler 6 is arranged above the vacuum feeder 5; the vacuum feeder 5 is connected to the mixing Roots blower 10 through the vacuum pipeline 11; the vacuum feeder 5 is connected to the feeding port of the conical mixer 7;

[0031] The feeding module includes a feeding temporary storage bin 13, a feeding conveying pipeline 14, a furnace table bin 15, a feeding recoiler 16, an electronic weighing device 17, a furnace table 18, a feeding Roots blower 19, and a feeding vacuum pipe 20; the feeding temporary storage bin 13 is connected to the furnace table bin 15 through the feeding conveying pipeline 14; a feeding recoiler 16 and an electronic weighing device 17 are arranged above the furnace table bin 15; the discharge port of the furnace table bin 15 is connected to the furnace table 18, and the furnace table bin 15 is connected to the feeding Roots blower 19 through the feeding vacuum pipe 20. A dust collector 2 is installed above the raw material bin 1, a mixing recoiler 6 is installed above the vacuum feeder 5, and a feeding recoiler 16 is installed above the furnace table bin 15 to solve the problem of dust overflow and improve the working environment. The materials in the feeding temporary storage bin 13 are fed to the furnace table bin 15 through the feeding conveying pipeline 14, which reduces the labor intensity.

[0032] Furthermore, it also includes an AGV trolley 8, a floor scale 9, and an AGV trolley track 21. The floor scale 9 is arranged below the discharge port of the conical mixer 7, and the AGV trolley 8 is placed on the floor scale 9, and the materials are transported to the temporary storage bin 13 through the AGV trolley track 21. The materials are fed into the raw material bin 1 by a forklift, and the AGV trolley 8 feeds the materials into the temporary storage bin 13, which reduces the labor intensity; in the process of transporting materials, the safety hazards of employees' pallet pressure feet and material bags slipping and injuring people are avoided.

[0033] Furthermore, the AGV trolley track 21 is a circular track, the number of the AGV trolleys 8 is 1-20, and the interval between every two AGV trolleys is not less than 20-60 meters. Multiple AGV trolleys 8 circulate back and forth to transport materials, thereby improving transportation efficiency.

[0034] Furthermore, the number of furnaces 18 is 1-60, and the number of furnace bins 15, feeding recoilers 16 and electronic weighing devices 17 is the same as that of the furnaces. The mixed rare earth materials are fed into the furnaces 18 for use according to the specified time and weight through the electronic weighing device 17, thereby avoiding the problem of too much or too little feeding when feeding manually.

[0037] The working process is as follows: according to the ingredient ratio, various rare earth materials are put into the raw material bin 1 from the feeding port 3 in turn, the dust collector 2 is turned on to prevent the rare earth dust from overflowing, and then the mixing Roots blower 10 is turned on to form a negative pressure in the vacuum pipe 11, and the rare earth materials are sucked into the vacuum feeder 5 through the mixing conveying pipe 4. The rare earth dust is temporarily adsorbed in the recoiler 6. At regular intervals, the recoiler 6 automatically flushes the adsorbed rare earth dust into the vacuum feeder 5; the rare earth materials in the vacuum feeder 5 enter the conical mixer 7, and after the mixing is completed in the conical mixer 7, the automatic control valve 12 is opened, and the AGV trolley 8 moves to the weighing scale 9 to pour the mixed rare earth materials into the AGV trolley 8. When the AGV trolley 8 is loaded to a certain weight, the valve 12 is opened. The data is transmitted to the automatic control valve 12 through the weighbridge 9, and the automatic control valve 12 is automatically closed. The AGV trolley 8 pours the mixed rare earth materials into the feeding temporary storage bin 13 through the AGV trolley track 21. At the same time, the next AGV trolley 8 moves to the weighbridge 9 to receive the materials; then the feeding Roots blower 19 is turned on to form a negative pressure in the vacuum pipe 20, and the mixed rare earth materials are sucked from the feeding temporary storage bin 13 to the furnace bin 15 through the feeding conveying pipe 14, and the rare earth dust is temporarily adsorbed in the recoiler 16. At regular intervals, the recoiler 16 automatically flushes the adsorbed rare earth dust into the furnace bin 15, and then the mixed rare earth materials are put into the furnace 18 for use according to the specified time and weight through the electronic weighing device 17.

[0038] Compared with manual operation, the use of this equipment for mixing and feeding can reduce more than half of the staff and reduce labor intensity. The time required for the entire work process is reduced by more than half, which improves work efficiency.
