[0036] The agitator 3 and the screw conveyor 102 are driven by the motor 8.

[0037] Principle and operation process

[0038] In the actual production process of zirconium oxychloride, in view of the strong corrosion of various materials involved, the corrosion-resistant and high-temperature-resistant material (such as: steel lined with polytetrafluoroethylene or polytetrafluoroethylene material) is selected to process each component, which can ensure that the device can stably and reliably operate in a corrosive environment, effectively prolong the service life of the device, and ensure the safety and continuity of the zirconium oxychloride production process.

[0039] The control system of the utility model receives sensor signals and controls each component, and the core waste heat utilization mechanism of the utility model is based on the heat exchange principle, the outlet pipe 5 carries the liquid with relatively high temperature after completing the stirring process, and the heat of the liquid is transmitted to the cavity wall through the contact with the heat preservation cavity 6. The heat preservation cavity 6 is arranged around the outlet pipe 5 and plays the role of heat collection; at the same time, the preheating cavity 101 drives hot air to enter from the air inlet pipe 61 by the air pump 611, and the material to be put into the stirring barrel 2 is preheated by the recycled heat, and the air inlet pipe 61 and the air return pipe 62 connected with each other form a closed heat transfer channel, the gas is transported to the preheating cavity 101 through the air inlet pipe 61 after absorbing heat in the heat preservation cavity 6, releases heat to the material in the feeding barrel 1, and then returns to the heat preservation cavity 6 through the air return pipe 62 to reabsorb heat, so as to realize the directional transfer of heat from the outlet pipe 5 to the material in the feeding barrel 1 and achieve the purpose of energy saving.

[0040] The stirrer 3 inside the stirring barrel 2 works in cooperation according to different blade characteristics. The folded blade 31 is located at the upper part. The folded blade is designed to exert strong shearing force and impact force on the material entering the stirring barrel 2 from the feeding barrel 1 through the screw conveyor 102 at high speed, so as to break the material aggregation state instantly, promote the rapid dispersion of the material, and preliminarily uniformly distribute the material on the starting layer of the reaction system. The inclined blade 32 pushes the material to flow in the radial direction, so as to not only mix the material further, but also strengthen the mutual diffusion of the materials in different concentration areas, so as to avoid the reaction lag or side reaction caused by the uneven concentration of local reactants. The anchor blade 33 at the bottom closely adheres to the bottom contour of the inner container 24, and sweeps the bottom of the barrel when the stirrer 3 rotates, so as to prevent the stagnant material accumulated due to gravity settling, ensure that all materials participate in the reaction without dead angle, maintain the uniformity of the composition of the reaction system, and accelerate the forward progress of the reaction.

[0041] The temperature sensor 7 monitors the solution temperature inside the inner container 24 in real time, generates an electric signal, and transmits the electric signal to the control system. The control system accurately controls the on-off of the heating sheet 23 according to the preset temperature threshold, and maintains the constant temperature of the reaction.

[0042] In use, first, the raw materials for preparing zirconium oxychloride are put into the feeding barrel 1 according to the formula proportion, the motor 8 is started to drive the screw conveyor 102, the screw blade inside the screw conveyor 102 rotates at a constant speed under the torque of the motor 8, and is continuously pushed to the feeding port of the stirring barrel 2. When the material enters the stirring barrel 2, the first electromagnetic valve 41 on the liquid inlet pipe 4 is opened, and the liquid reagent required for the reaction is introduced at the flow rate required by the process.

[0043] When the material and the reagent are in place and the temperature meets the standard, the stirrer 3 operates, the folded blade 31 disperses the newly incoming material at high speed, then the inclined blade 32 continuously strengthens the mixing, so that the molecules of the material and the reagent fully collide and contact, and the dissolution reaction rapidly develops, and the anchor blade 33 maintains the suspension flow of the material. During the reaction process, the temperature sensor 7 monitors and transmits the data to the control system in real time, and the heating sheet 23 is started and stopped as required to balance the heat. If the solution in the inner container 24 is lower than the preset temperature, the heating sheet 23 is powered on to assist in heating until the preset temperature is reached, so as to ensure the constant temperature and high efficiency of the reaction, and promote the full reaction and conversion of the zirconium raw material and the reagent into the zirconium oxychloride solution.

[0044] When the generated zirconium oxychloride solution meets the process requirements such as concentration and other indicators, the second electromagnetic valve 51 of the liquid outlet pipe 5 is opened, and the solution is discharged to the subsequent processing procedures such as crystallization, purification and the like. When the solution is discharged, the waste heat utilization mechanism is started, the air pump 611 operates to promote the circulation of the gas in the heat preservation cavity 6 and the preheating cavity 101, the waste heat of the liquid outlet pipe 5 is collected to preheat the material in the feeding barrel 1, the device is operated in a cycle, and the zirconium oxychloride solution is continuously output.

[0045] Since the zirconium oxychloride is active and volatile at a high temperature, the waste heat utilization system does not need to be started when the solution is prepared at a high ambient temperature.

[0046] Although the specific embodiments of the utility model are described above in combination with the drawings, it is not a limitation on the protection scope of the utility model, various modifications or deformations made by the person skilled in the art on the basis of the technical scheme of the utility model without paying creative labor are still within the protection scope of the utility model.
