Description

Technical Field

[0001] The present invention relates to the technical field of drying and sampling of niobium hydroxide, and more particularly to a sampling device for drying niobium hydroxide. Background Art

[0002] Niobium hydroxide needs to be calcined during the processing process. Before calcination, the moisture in the niobium hydroxide needs to be dried to achieve favorable conditions for the calcination process. Therefore, drying equipment is required to dry the niobium hydroxide.

[0003] The working principle of existing niobium hydroxide drying equipment is to use electric heating resistance wire to heat and use heated air to dry the niobium hydroxide. When in use, the niobium hydroxide is placed in the internal space of the drying equipment and heated. However, in reality, traditional drying equipment still has the following disadvantages:

[0004] In conventional niobium hydroxide drying equipment, after drying the niobium hydroxide, the niobium hydroxide must be removed from the drying equipment and then sampled using a sampling device. The niobium hydroxide must then be cooled. This entire process is cumbersome and requires the use of two separate instruments, significantly reducing work efficiency. Consequently, conventional niobium hydroxide drying equipment has a single function and low efficiency.

[0005] When sampling niobium hydroxide using conventional niobium hydroxide drying equipment under existing technology, the niobium hydroxide needs to be removed from the drying equipment for cooling, then crushed, and then sampled. However, conventional drying equipment does not have both cooling and crushing functions. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sampling device for drying niobium hydroxide to solve the problems existing in the above-mentioned background technology.

[0016] Technical effects and advantages of the present invention:

[0017] 1. The present invention comprises a cooling assembly and a sampling assembly. When used as a sampling device for drying niobium hydroxide, the inlet fan blows external air into the interior of the housing, the exhaust fan draws air from the housing into the U-shaped tube, and the exhaust fan exhausts the gas in the U-shaped tube to the outside environment. This structure achieves a cooling function. Because the gas in the upper portion of the U-shaped tube has a certain flow rate, the pressure inside the upper portion of the U-shaped tube is relatively low, allowing the sampler to draw niobium hydroxide powder from the bottom plate into its internal cavity, thereby completing the sampling operation. This structure integrates the drying, cooling, and sampling operations of niobium hydroxide, greatly improving work efficiency.

[0018] 2. The present invention features a sealing assembly and a cooling assembly. When the sampling device for drying niobium hydroxide is in use, the cooling assembly provides cooling, while the motor drives the pulverizing shaft to rotate, stirring and pulverizing the niobium hydroxide on the placement plate. The connection between the movable rod and the sealing plate chute allows for flexible adjustment of the pulverizing shaft's stirring height and angle. This structure allows the machine to achieve both cooling and pulverizing effects. BRIEF DESCRIPTION OF THE DRAWINGS

There is no special limitation on the model of the air intake fan 102.

[0032] In this embodiment, the function of the exhaust fan 502 is to draw the internal air of the box shell 101 into the U-shaped tube 501, and the function of the exhaust fan 503 is to discharge the gas in the U-shaped tube 501 to the external environment. The models of the exhaust fan 502 and the exhaust fan 503 are the same and are not specifically limited.

[0033] Reference Figure 6 The sealing assembly 2 includes a sealing plate 201. The inner wall surface of the sealing plate 201 is provided with evenly distributed movable grooves.

[0035] Working principle of the present invention: When the sampling device for drying niobium hydroxide is used, the niobium hydroxide to be dried is first placed on the placement plate 402, and then the box shell 101 is sealed with the sealing plate 201. Then, the heating tube 302 starts to heat the air inside the box shell 101, thereby achieving the drying effect of the niobium hydroxide on the placement rack 401. After the drying is completed, the heating tube 302 stops heating. At this time, the air intake fan 102 blows the external air into the interior of the box shell 101, the exhaust fan 502 draws the internal air of the box shell 101 into the U-shaped tube 501, and the exhaust fan 503 discharges the gas in the U-shaped tube 501 to the external environment. The gas flow direction is as follows: Figure 2As shown, rapid cooling can be achieved. At the same time, the cavity of the sampler 601 is connected to the tube body of the upper U-shaped tube 501 by adjusting the valve 602. Since the gas in the tube body above the U-shaped tube 501 has a certain flow rate, the internal pressure of the tube body above the U-shaped tube 501 is relatively low, so that the sampler 601 draws the niobium hydroxide powder on the bottom placement plate 402 into its internal cavity, thereby completing the sampling operation. The suction speed of the niobium hydroxide powder can be controlled by rotating the regulating valve 602. The sampler 601 can be removed from the bottom of the U-shaped tube 501 by connecting with the threaded nozzle 603. By observing the scale groove provided on the sampler 601, the operation of accurately removing the material can be achieved. The motor 202 can drive the crushing shaft 204 to rotate to achieve the stirring and crushing effect of the niobium hydroxide in the placement plate 402. The stirring height and angle of the crushing shaft 204 can be flexibly adjusted by the connection structure between the movable rod 203 and the sliding groove of the sealing plate 201.
