Description

Technical Field

[0001] The utility model relates to the field of solution transportation, in particular to a solution transfer vehicle and a solution transportation device. Background Art

[0002] The solution transfer vehicle can be used for transporting solution materials to a desired working area. For crystal solutions, their saturation is closely related to crystallization; factors such as solubility, temperature, container size, and the nature of the solute will all affect the saturation of the solution. If the solution reaches a saturated state and the corresponding conditions change, solute will crystallize from the solution.

[0003] At present, in order to ensure the relative stability of temperature and prevent solute precipitation, the current solution transfer vehicle is usually equipped with heating facilities; for example, by setting infrared lamps at the bottom of the insulation cylinder of the transfer vehicle for heating and installing thermocouples for detection to achieve temperature control of the air in the area near the infrared lamps; although this method can achieve the purpose of heating and temperature control, its heating and temperature control methods are simple. The infrared lamp heating method is prone to cause temperature difference defects, resulting in uneven actual temperature distribution of the solution in the solution bottle, and the temperature control accuracy is not good; when the transfer stage time of the solution is too long, this method is extremely likely to precipitate solute and is difficult to meet the actual use requirements of solution transportation.

The vehicle body 1 is used to transfer the solution bottles 2 loaded on the loading cylinder 3.

[0042] In this embodiment, the loading cylinder 3 is connected to the vehicle body 1. The loading cylinder 3 includes an inner cylinder 31, an outer cylinder 33, and a cylinder bottom wall 34. The outer cylinder 33 is sleeved on the outer peripheral side of the inner cylinder 31. The cylinder bottom wall 34 is connected to the bottom sides of the inner cylinder 31 and the outer cylinder 33. The inner cylinder 31 and the cylinder bottom wall 34 together form a loading position suitable for fitting and loading the solution bottles 2. Of course, this loading position can be directly formed by the inner cylinder 31.

[0043] The heating assembly includes a first heating element 41 and a second heating element 42. The first heating element 41 is arranged on the outer wall surface of the inner cylinder 31. The second heating element 42 is arranged on the side of the cylinder bottom wall 34 close to the inner cylinder 31. Any heating element is thermally connected to the loading cylinder 3. The controller is installed on the vehicle body 1. The controller is electrically connected to the first heating element 41 and the controller is electrically connected to the second heating element 42.

[0044] For the solution transfer vehicle provided in this embodiment, by actively configuring the heating modes of the first heating element 41 and the second heating element 42 in the heating assembly by the controller, the inner cylinder 31 transfers the heat generated by the operation of the first heating element 41 to the peripheral area of the solution bottle 2. The outer cylinder 33 forms an outer shield for the inner cylinder 31 and the first heating element 41, and stably limits and assembles the first heating element 41 between the inner cylinder 31 and the outer cylinder 33.

With this setting, during the heating stage when the controller is working, the first temperature measuring element 61 detects the temperature parameter of heat conduction at the inner cylinder 31, and the second temperature measuring element 62 detects the temperature parameter of heat conduction at the bottom wall 34 of the cylinder. During the heat preservation stage, the first temperature measuring element 61 can detect the temperature parameter of the solution in the solution bottle 2 near the inner cylinder 31, and the second temperature measuring element 62 can detect the temperature parameter of the solution in the solution bottle 2 near the bottom wall 34 of the cylinder. According to the temperature parameters detected by the first temperature measuring element 61 and the second temperature measuring element 62, the user can actively adjust the heating power of the first heating element 41 and the second heating element 42 through the controller, so as to adjust the heat output from the first heating element 41 and transferred to the inner cylinder 31, and adjust the heat output from the second heating element 42 and transferred to the bottom wall 34 of the cylinder, so that the temperature of the solution in the solution bottle 2 reaches the set target temperature and meets the requirements of constant temperature and heat preservation control.
