Description

Technical Field

[0001] The invention relates to the technical field of pickling tanks, in particular to a jet constant temperature pickling tank. Background Art

[0002] In many industrial fields, such as metal processing and surface treatment, pickling is a common process used to remove impurities such as scale, rust, and oil from the surface of metal workpieces to improve the surface quality and subsequent processing performance of the workpieces. The jet constant temperature pickling tank uses a jet device installed in the tank to force the acid liquid to circulate, improving the uniformity of the acid liquid and the contact efficiency with the workpiece, thereby improving the pickling effect. At the same time, it is equipped with a constant temperature control system to accurately control the acid liquid temperature, ensuring that the pickling process is carried out under stable temperature conditions, improving product quality and production efficiency.

[0003] To this end, the patent with authorization announcement number CN110565105B discloses a disc pickling tank, including a tank body, a conveyor, a dryer and a control device, wherein the tank body is divided into several cavities from left to right by a partition, and the dryer includes a cylinder, a first motor, a cover body and a barrel body, the first motor is fixed to the bottom end of the telescopic rod of the cylinder, the cover body is fixed to the bottom end of the output shaft of the first motor and closes the top opening of the barrel body, the side wall and the bottom plate of the barrel body are respectively evenly provided with several leakage holes, the top surface of the bottom plate of the barrel body protrudes upward to form an annular convex wall, the cylinder is connected to the conveyor so as to be horizontally transported and moved to the upper center of each cavity of the tank body, the control device is electrically connected to the conveyor and the dryer, so as to realize multi-pass pickling treatment of the disc element, while reducing the amount of waste liquid entrained in the gap of the disc element and slowing down the concentration change of the subsequent treatment liquid during the pickling process;

[0004] The aforementioned prior art solutions suffer from the following drawbacks: while they can mitigate concentration changes in the post-processing solution during the pickling process, they are unable to agitate the acid solution within the pickling tank, leaving it to flow only to a limited extent within the tank by natural diffusion. This results in extremely uneven distribution of the acid solution within the pickling tank, making it very easy for localized concentrations to be excessively high or low. This prevents uniform pickling of various parts of the workpiece, impacting the quality of the pickling process. Summary of the Invention

[0038] By starting the drive motor 23, the first rotating rod 24 can be rotated, driving the first gear 25 to rotate. Since the first gear 25 is meshed with the second gear 26, the second gear 26 can be rotated in the opposite direction of the first gear 25, so that the air flow rate near the side of the intake pipe 28 is accelerated, and the air is drawn into the air collecting shell 21 through the intake pipe 28.

The handle 73 and the positioning buckle 74 form a rotating structure, and the positioning buckle 74 is engaged with the positioning block 76.

[0042] By moving the acid delivery pipe 75 so that it can be docked and inserted into one end of the jet pipe 5, the positioning buckle 74 is buckled on the positioning block 76, and the handle 73 is pressed. Under the action of the movable shaft 72, the handle 73 can be rotated along the positioning base 71, and at the same time, the positioning buckle 74 is driven to buckle the positioning block 76, so that the jet pipe 5 and the acid delivery pipe 75 can be stably installed.
