Description

Technical Field

[0001] The utility model relates to the technical field of alkali solution transportation, in particular to an automatic alkali solution loading device. Background Art

[0002] The chlor-alkali industry refers to the industry that produces caustic soda (NaOH), chlorine (Cl2) and hydrogen (H2) by electrolyzing saturated NaCl solution, and uses them as raw materials to produce a series of chemical products.

[0003] An existing patent CN219174208U discloses an alkali liquid filling system, in which the support structure includes a mobile platform, a first guide rail and a first drive device. The mobile platform includes a second guide rail, a lifting device and a second drive device. The lifting device is arranged on the second guide rail. The liquid loading and unloading arm is arranged on the mobile platform and can move with the mobile platform. The first end of the liquid loading and unloading arm is connected to the alkali liquid storage unit, and the second end of the liquid loading and unloading arm is connected to the lifting device. The control system is connected to the first drive device, the second drive device and the lifting device, and is used to control the movement of the second end of the liquid loading and unloading arm to insert it into the filling port of the transport vehicle. The alkali liquid filling system can prevent people from directly contacting the filling equipment, eliminating various safety risks such as alkali liquid burns, mechanical injuries, and falls from heights caused by improper manual operation. Since some alkali liquid adheres to the filling head during the filling process, the alkali liquid drips after the filling device moves, which can easily corrode the items below.
