The solution meeting the target concentration is reserved for use, and the solution not meeting the target concentration is continuously frozen and dissolved using the freeze concentration device to achieve the concentration of the dilute solution. However, this freeze concentration device is suitable for the freeze concentration of dilute solutions and is not suitable for the concentration of laboratory titanium liquid.

[0022] Advantages of the present utility model

[0023] 1. Existing laboratory titanium liquid concentration devices cannot accurately determine the concentration of titanium liquid during the concentration process, while the present utility model

[0031] Figure 1This is a schematic structural diagram of the present utility model. The present utility model provides a laboratory titanium liquid concentration device. The device includes a vacuum device, a concentration device, and a condensation device. The vacuum device and the condensation device are respectively connected to the concentration device through pipelines. The vacuum device is used to reduce the concentration temperature of the titanium liquid and shorten the concentration time of the titanium liquid, thereby improving the stability of the concentrated titanium liquid and further ensuring the quality of titanium dioxide. The concentration device is used to concentrate the titanium liquid. The condensation device is used to condense the titanium liquid and observe the amount of water evaporated from the titanium liquid, thereby accurately judging the concentration of the titanium liquid during the concentration process and further ensuring the quality of titanium dioxide.

[0032] Optionally, the vacuum device includes a vacuum pump 1.

[0033] The vacuum device includes a vacuum pump 1. On the one hand, the vacuum pump 1 reduces the gas pressure by pumping out gas molecules from the device to form a certain degree of vacuum. This vacuum environment helps to reduce the boiling point of the titanium liquid, thereby realizing the concentration of the titanium liquid at a lower temperature. On the other hand, in the vacuum environment, the gas molecules on the surface of the titanium liquid are quickly pumped away, causing the vapor pressure on the surface of the titanium liquid to decrease, thus accelerating the evaporation process of the titanium liquid. This accelerated evaporation can significantly shorten the concentration time of the titanium liquid.

[0034] Optionally, the concentration device includes a housing 2, a concentration reaction tank 3, a heater 4, a stirrer, and a discharge port 5.

[0035] The housing 2 provides necessary structural protection for the entire concentration device. The concentration reaction tank 3 is the place where the titanium liquid is concentrated. The heater 4 ensures that the titanium liquid reaches the required temperature range during the concentration process by providing a stable heat source. The stirrer makes the titanium liquid mix evenly in the concentration reaction tank 3 through the rotation of the stirring shaft 9 and the stirring paddle 10, preventing problems such as local overheating or uneven concentration. The discharge port 5 discharges the concentrated titanium liquid from the concentration device for subsequent condensation treatment.

[0036] Furthermore, the condensation device includes a condenser 6, an observation port 7, and a condensate outlet 8.

[0037] An observation port 7 with scales is provided outside the condenser 6, which can clearly determine the amount of water evaporated from the titanium liquid, thereby accurately judging the concentration of the titanium liquid during the concentration process and further ensuring the quality of titanium dioxide.

[0038] Furthermore, the pressure of the vacuum device is (-0.06) - (-0.1) Mpa.

[0039] The pressure of the vacuum device being (-0.06) - (-0.1) Mpa is the preferred pressure for the concentration of the titanium liquid.

[0040] Furthermore, the concentration reaction tank 3 is detachably placed inside the housing 2. A heater 4 is provided between the concentration reaction tank 3 and the housing 2. A stirrer is provided at the top of the concentration reaction tank 3, and a discharge port 5 is provided at the bottom of the concentration reaction tank 3.

[0041] Furthermore, the outer shell 2, the concentration reaction tank 3, and the pipelines are made of acid-resistant materials.

[0042] The acid-resistant outer shell 2 can effectively resist the erosion of acidic substances in the external environment, protect the internal structure from corrosion, and extend the service life of the overall equipment. The concentration reaction tank 3 often needs to handle acidic substances, and the acid-resistant material can resist the corrosion of these substances to ensure the integrity and stability of the reaction tank. The acid-resistant pipelines can ensure the safety and stability of the transportation process.

[0043] Furthermore, the shape of the outer shell 2 is a cube.

[0044] Furthermore, the concentration temperature of the heater 4 is 55 - 65 °C.

[0045] The concentration temperature of the heater 4 being 55 - 65 °C is the preferred temperature for titanium liquid concentration.

[0046] Furthermore, the stirrer includes a stirring shaft 9 and stirring paddles 10, and the stirring paddles 10 are placed at the bottom of the stirring shaft 9.

[0047] Furthermore, a graduated observation port 7 is provided outside the condenser 6, and a condensate outlet 8 is provided at the bottom of the condenser 6.

[0048] Furthermore, the observation port 7 is made of a transparent material and can observe the amount of water evaporated from the titanium liquid.
