Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a rapid cleaning and stirring device for mobile storage tanks. Background Art

[0002] In the polyimide polymerization experiment stage, due to continuous small-scale tests, mobile storage tanks are often used to store various test stock solutions for spinning. However, because of different experiment formulations, the mobile storage tanks need to be frequently and repeatedly cleaned to ensure that the stock solutions in the mobile storage tanks are not mixed. Such cleaning of mobile storage tanks requires a large amount of manpower and material resources, and the cleaning efficiency is not very high.

[0003] In the conventional cleaning process, two to three personnel are required to participate. Since there are residual chemical reagents inside the mobile storage tank, the cleaning personnel need to wear gas masks, neoprene gloves, goggles and other protective equipment. The personnel operation steps first require removing the cover plate of the mobile storage tank. The cover plate of the mobile storage tank is heavy and there are many screws around it. The removal process takes about 2 - 3 hours. A manual hoist needs to be installed at a high place to lift the cover plate into the cleaning tank. Corrosion-resistant tools are used to clean the residual chemicals inside the mobile storage tank. After the residue is cleaned, a specific chemical reagent is used to clean the inside of the mobile storage tank for the second time. After cleaning, the residue and waste liquid are poured into the waste liquid recovery system. The cleaned cover plate of the mobile storage tank is lifted to the upper part of the storage tank by the hoist, and the operator installs the screws. After installation, nitrogen needs to be connected to blow the inside of the storage tank clean. The process is complex and time-consuming, and there is also a risk of poisoning for the cleaning personnel. Summary of the Utility Model

[0017] The following are specific embodiments of the present utility model in combination with the drawings, and the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.

[0018] Such as Figure 1 and 2As shown in the figure, a rapid cleaning and stirring device for a mobile storage tank 5 of the present utility model includes a driving member 1, a transmission screw 2, and a delivery pipe 3. The transmission screw 2 is hollow inside and open at the bottom. A plurality of cleaning holes 21 are arranged at intervals along the axial direction of its outer wall. A paddle 4 is provided on the outer periphery of the transmission screw 2. The transmission screw 2 is arranged inside the mobile storage tank 5. The driving member 1 is arranged on the top of the mobile storage tank 5 and is drivingly connected to the top of the transmission screw 2 to drive the transmission screw 2 to rotate. The delivery pipe 3 extends into the transmission screw 2 from the bottom of the mobile storage tank 5, and the delivery pipe 3 is connected to a cleaning agent source and a nitrogen source.

[0019] The stirring device of the present utility model uses a driving member 1 plus a transmission screw 2. A delivery pipe 3 is provided at the bottom of the transmission screw 2. The delivery pipe 3 is connected to a cleaning agent and nitrogen. The transmission screw 2 is provided with independent holes. When the cleaning agent valve on the delivery pipe 3 is opened during rotation, the cleaning agent can be evenly sprayed inside the mobile storage tank. When cleaning the mobile storage tank 5, only the transmission screw 2 with the driving member 1 needs to be placed inside the mobile storage tank 5, the screws are fixed at the top, the cleaning agent is introduced and stirring is started for repeated cleaning. After cleaning, the waste liquid is discharged into the recovery system, and the nitrogen valve on the delivery pipe 3 is opened to blow the inside of the mobile storage tank clean.
