Description

Technical Field

[0001] This application relates to the field of terbium oxide processing technology, specifically a high-temperature calcination device for processing high-purity terbium oxide. Background Technology

[0002] Terbium oxide is an oxide, appearing as a dark brown powder. It is used in the manufacture of metallic terbium, magneto-optical glass, phosphors, magneto-optical storage devices, and chemical additives. The processing of terbium oxide requires calcination in an electrically heated rotary kiln to produce qualified terbium oxide.

[0003] In existing electrically heated rotary kilns, the inner cylinder is not easily cooled, which reduces the processing rate of terbium oxide.

[0004] Therefore, there is an urgent need for a high-temperature calcination equipment for processing high-purity terbium oxide to solve the problem of low processing speed in electrically heated rotary kilns. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a high-temperature calcination device for processing high-purity terbium oxide, which has the advantages of convenient and rapid cooling, and solves the problem of low processing speed in electrically heated rotary kilns.

[0006] To achieve the above objectives, this application provides the following technical solution: a high-temperature calcination device for processing high-purity terbium oxide, comprising a base, an electrically heated rotary kiln, an inner cylinder, and a connector. The electrically heated rotary kiln is installed on the top of the base, the inner cylinder is rotatably connected to the inside of the electrically heated rotary kiln, the connector is installed on the top of the electrically heated rotary kiln and electrically connected to the heating components inside the electrically heated rotary kiln, a heat dissipation mechanism is provided on the top of the base, and a dispersion structure is provided inside the inner cylinder.

[0007] The heat dissipation mechanism includes a pipe heater, a controller, a connecting pipe, an automatic valve, and a connecting pipe support. The pipe heater and the connecting pipe are installed on the top of the base. The two ends of the connecting pipe are connected to the pipe heater and the connecting pipe support, respectively. The two ends of the connecting pipe support are connected to the heating groove formed by the electric heating rotary kiln and the inner cylinder. The automatic valve is installed on the connecting pipe.

[0008] By mixing gas and water for cooling, the electrically heated rotary kiln can be cooled down quickly, enabling it to rapidly calcine terbium oxide at high temperatures and achieve high purity terbium oxide.

[0009] Preferably, the connecting pipe is electrically connected to the pipe heater.

[0010] Preferably, a second connecting pipe is installed on one side of the electrically heated rotary kiln, and a nozzle is installed on the inner side of the second connecting pipe.

[0011] Preferably, several sets of the connecting pipes and nozzles are linearly distributed on one side of the electrically heated rotary kiln, and a discharge pipe is installed at one end of the electrically heated rotary kiln.

[0012] Preferably, the dispersion structure includes baffles and protrusions, which are welded to the inner surface of the inner cylinder, and the baffles are arc-shaped plates.

[0013] Preferably, several groups of the protrusions are linearly distributed on the inner surface of the inner cylinder.

[0014] In summary, this application includes at least one of the following beneficial effects:

[0015] 1. In this high-temperature calcination equipment for processing high-purity terbium oxide, after terbium oxide is introduced into the inner cylinder for calcination, inert gas is introduced into the pipe heater when the inner cylinder needs to be cooled. The pipe heater heats the inert gas, and the temperature gradually decreases, thereby rapidly reducing the temperature of the inner cylinder and increasing the cooling rate of the electrically heated rotary kiln. When the inner cylinder reaches a suitable temperature, external water enters the nozzle through the connecting pipe 2. The water is sprayed out from the nozzle to cool the inner cylinder. Through the cooling effect of the gas and water mixture, the electrically heated rotary kiln can be cooled rapidly, enabling it to quickly calcine terbium oxide and achieve high-purity terbium oxide at high temperatures.

[0016] 2. In this high-temperature calcination equipment for processing high-purity terbium oxide, when high-purity terbium oxide is introduced into the inner cylinder, the high-purity terbium oxide is blocked and shielded by baffles and protrusions, which allows the high-purity terbium oxide to be quickly dispersed and mixed evenly, thereby improving the purity of calcined terbium oxide.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Please see Figure 1-5 A high-temperature calcination device for processing high-purity terbium oxide includes a base 1, an electrically heated rotary kiln 2, an inner cylinder 3, and a connector 4. The electrically heated rotary kiln 2 is installed on the top of the base 1. The high-purity terbium oxide introduced into the electrically heated rotary kiln 2 is calcined by the electrically heated rotary kiln 2. The inner cylinder 3 is rotatably connected to the inside of the electrically heated rotary kiln 2. The connector 4 is installed on the top of the electrically heated rotary kiln 2 and electrically connected to the heating components inside the electrically heated rotary kiln 2. After the connector 4 is connected to the circuit, the heating components inside the electrically heated rotary kiln 2 perform high-temperature calcination of the high-purity terbium oxide. A heat dissipation mechanism is provided on the top of the base 1, and a dispersion structure is provided inside the inner cylinder 3.

[0025] The base 1 is installed at an angle. Through an external drive device, the gears on the outer surface of the inner cylinder 3 are rotated, thereby causing the inner cylinder 3 to rotate, so that the high-purity terbium oxide can be calcined evenly.

[0026] Specifically, the heat dissipation mechanism includes a pipe heater 111, a controller 112, a connecting pipe 113, an automatic valve 114, and a connecting pipe support 115. The pipe heater 111 and the connecting pipe 113 are installed on the top of the base 1. The connecting pipe 113 is electrically connected to the pipe heater 111. Both ends of the connecting pipe 113 are connected to the pipe heater 111 and the connecting pipe support 115, respectively. Both ends of the connecting pipe support 115 are connected to the heating groove formed by the electric heating rotary kiln 2 and the inner cylinder 3. The automatic valve 114 is installed on the connecting pipe 113. A connecting pipe 2 116 is installed on one side of the electric heating rotary kiln 2. A nozzle 117 is installed inside the connecting pipe 2 116. Several sets of connecting pipe 2 116 and nozzles 117 are linearly distributed on one side of the electric heating rotary kiln 2. A discharge pipe 118 is installed at one end of the electric heating rotary kiln 2.

[0027] Through the above technical solution, after the automatic valve 114 is opened, the connecting pipe 116 connects to the external water pipe. The working principle of the pipe heater 111 is to convert electrical energy into heat energy, and use the Joule effect of the heat generated by the resistive material when current passes through to directly heat the medium flowing through the pipe. At the same time, precise temperature control is achieved through temperature sensors and control systems. When terbium oxide is introduced into the inner cylinder 3 for calcination, and the inner cylinder 3 needs to be cooled, inert gas is introduced into the pipe heater 111. The pipe heater 111 heats the inert gas, and the temperature is gradually reduced. The inert gas is then introduced into the electrically heated rotary kiln 2 to cool the inner cylinder 3. This allows the temperature of the inner cylinder 3 to drop rapidly, thereby increasing the cooling rate of the electric heating rotary kiln 2. When the inner cylinder 3 drops to a suitable temperature, external water enters the nozzle 117 through the connecting pipe 116. The water is sprayed out from the nozzle 117 to cool the inner cylinder 3. Through the cooling effect of the mixture of gas and water, the electric heating rotary kiln 2 can be cooled rapidly, allowing it to quickly calcine terbium oxide and achieve high-purity terbium oxide at high temperatures. The discharge pipe 118 is connected to the slot between the electric heating rotary kiln 2 and the inner cylinder 3, and water and inert gas are discharged from the discharge pipe 118.

[0028] Specifically, the dispersion structure includes baffles 211 and protrusions 212. The baffles 211 and protrusions 212 are welded to the inner surface of the inner cylinder 3. The baffles 211 are arc-shaped plates, and several sets of protrusions 212 are linearly distributed on the inner surface of the inner cylinder 3.

[0029] Through the above technical solution, when high-purity terbium oxide is introduced into the inner cylinder 3, the high-purity terbium oxide is blocked and shielded by the baffle 211 and the protrusion 212, so that the high-purity terbium oxide can be quickly dispersed and mixed evenly, thereby improving the purity of calcined terbium oxide.

[0030] During use, the electric heating rotary kiln 2 can be cooled down quickly by mixing gas and water, which allows it to calcine terbium oxide rapidly at high temperatures, enabling it to quickly calcine high-purity terbium oxide.

[0031] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
