Description

Technical Field

[0001] The utility model relates to the technical field of powder feeding, in particular to a monazite ore powder feeding device. Background Art

[0002] In the process of processing and utilization of monazite powder, feeding is a crucial link. At present, negative pressure feeding devices are usually used for feeding monazite powder, and the device sucks the monazite powder into the equipment through the air pressure difference generated by a vacuum device.

[0003] However, due to the special physical and chemical properties of monazite powder, when it is sucked into the negative pressure feeding device, it is easy to adhere to the surface of the filter element of the device. Over time, this adhesion phenomenon will cause the air permeability of the filter element to gradually deteriorate, thus affecting the smooth extraction of air inside the negative pressure feeding device. When the air permeability of the filter element drops to a certain extent, the negative pressure value inside the device cannot be maintained stably, and further affects the feeding efficiency and quality of monazite powder.

[0004] Secondly, problems such as improper grinding are likely to occur during the grinding process of monazite powder, such as uneven particle size distribution, too large or too small particle size, etc., resulting in the accumulation of monazite powder at the discharge port during the feeding process. When lumps are generated inside the monazite powder, its fluidity will be greatly reduced, further exacerbating the accumulation phenomenon at the discharge port, which will not only block the feeding channel, reduce the feeding efficiency, but also may damage the equipment. Summary of the Utility Model

[0005] In order to solve the existing technical problems of filter element blockage and uneven particle size and easy caking, the utility model provides a monazite ore powder feeding device.

[0006] The technical solution of the utility model is realized through the following scheme: A monazite ore powder feeding device includes a feeding box, a grinding and crushing assembly, a fixing piece and a brush cleaning piece. The feeding box is provided with a feeding pipe and a discharging pipe. A grinding and crushing assembly and a vacuum pump are installed on the feeding box. The vacuum pump is connected to a filtering tank. The grinding and crushing assembly is provided with a brush cleaning piece adapted to the filtering tank. The inner wall of the feeding box is fixedly installed with a fixing piece, and the grinding and crushing assembly is located at the center of the fixing piece.

[0007] Through the above technical scheme, through the cooperation of the vacuum pump and the filtering tank, the suction and filtration of ore powder are realized. At the same time, the filtering tank is cleaned in real time by using the brush cleaning piece to prevent the ore powder from blocking the filter element, ensuring the smooth operation of the device. The cooperation of the grinding and crushing assembly and the fixing piece can uniformly crush and grind the ore powder, improve the particle size uniformity of the ore powder, reduce the occurrence of caking phenomenon, and ensure the smooth progress and efficient coordination of steps such as feeding, grinding, and cleaning, thereby improving the production efficiency of the entire device.

[0008] Preferably, the grinding and crushing assembly includes a motor, a first rotating blade, a second rotating blade, a third rotating blade and grinding hammers.

The first fixing plate and the second fixing plate are both fixedly installed on the inner side wall of the feeding box. The first fixing plate and the second fixing plate are both annularly distributed. The first fixing plate is located between the first rotating blade and the second rotating blade, and the second fixing plate is located between the second rotating blade and the third rotating blade.

[0012] Preferably, a support frame is installed below the feeding box.

[0013] Preferably, electric valves are provided on both the feeding pipe and the discharging pipe.

[0014] Through the above technical solutions, through the combination of multiple rotating blades and grinding hammers driven by the motor, the monazite ore powder ensures that the ore powder can be fully ground, improving the fineness and uniformity of the ore powder discharge. The linkage design of the brush cleaning blade and the filter tank enables the ore powder residue on the filter tank to be cleaned in real time during the grinding process, effectively preventing the blockage of the filter tank and ensuring the continuous and stable operation of the equipment. The discharging part is designed in the shape of an inverted frustum of a cone, and the ore powder flows more smoothly towards the discharging port after grinding, effectively reducing the residence time of the material in the box.

The grinding and pulverizing assembly 2 is located at the center of the feeding box 1 and penetrates into the feeding box 1 and penetrates through the fixing piece 3 on the inner wall of the feeding box 1, which can ensure that the materials are evenly distributed in the box and receive equal grinding force, so as to achieve an efficient grinding and pulverizing effect and avoid blocking the feeding device. Electric valves are provided on both the feeding pipe 7 and the discharging pipe 8. A support frame is installed below the feeding box 1. The brush cleaning piece 6 is in the shape of a semi-cylindrical fan and is adapted to the cylindrical filter tank 4.

The setting of the electric valve ensures the precise control of the feeding and discharging processes, improving the safety and reliability of the equipment.

[0026] As Figure 3 shown, the grinding and pulverizing assembly 2 includes a motor 21, a first rotating piece 22, a second rotating piece 23, a third rotating piece 24 and grinding hammers 25. The first rotating piece 22, the second rotating piece 23, the third rotating piece 24 and the grinding hammers 25 are sequentially connected to the motor 21 through a rotating shaft. The motor 21 is located on the top surface of the feeding box 1. The rotating shaft is located at the axis center of the fixing piece 3. The brush cleaning piece 6 is connected to the outer surface of the filter layer through a rotating shaft. The brush cleaning piece 6 is located between the first rotating piece 22 and the filter tank 4. The diameters of the first rotating piece 22 and the third rotating piece 24 are slightly smaller than that of the second rotating piece 23.

The double grinding ensures that the monazite powder is evenly fed.

[0028] Working principle: start the vacuum pump 5 to absorb the air in the feeding box 1, so as to form a negative pressure environment in the feeding box 1, and then open the feeding pipe valve. At this time, the monazite powder is sucked into the feeding box 1 due to the pressure difference, and then start the motor 21 to drive the first rotating plate 22, the second rotating plate 23, the third rotating plate 24, the grinding hammer 25 and the brush cleaning plate 6 to rotate through the rotating shaft. The sucked block monazite powder is first effectively broken and preliminarily ground by the synergistic effect of multiple rotating plates and the fixed plate 3.
