[0034] In some embodiments, the base 12 is provided with a plurality of casters at its bottom for easy movement.

[0035] Working principle: The bracket 6 is fixedly installed on the base 12, serving as the support for the valve assembly. The feed tank 10 is used for temporary storage during acid or alkali unloading. A pipeline connects the feed tank 10 and the corrosion-resistant pump 7, with a first valve 9 installed on the pipeline. During operation, the first valve 9, the second valve 8, and the third valve 4 are manually opened. The acid or alkali in the feed tank 10 passes through the corrosion-resistant pump 7. At the outlet end of the corrosion-resistant pump 7, a rubber connector 5 is connected via a bend 11. When unloading acid or alkali into the acid / alkali tank, the final outlet height of the valve assembly needs to exceed that of the acid / alkali tank. Therefore, the bend 11 is upward-facing and fixed on the bracket 6. The bend of the bend 11 is positioned at a height higher than the required unloading point. At the location of the acid and alkali tank, the electric ball valve 3 includes a wireless connection module and a control module. The other end of the rubber connector 5 is fixedly connected to the third valve 4, the electric ball valve 3 and the electromagnetic flow meter 2 in sequence through a flange. The electromagnetic flow meter 2 is fixedly installed on the bracket 6. Acid or alkali flows through the electromagnetic flow meter 2. The flow rate of acid or alkali can be set by the electromagnetic flow meter. After the set flow rate is reached, a wireless signal is sent to the electric ball valve 3 to close the electric ball valve 3. The electric ball valve 3 can also be actively closed and opened by an external controller. The discharge tee 1 is fixedly connected to the electromagnetic flow meter 2 at the first end. The second end of the discharge tee 1 is set horizontally. When the second end of the discharge tee 1 is working, it discharges material into the acid and alkali tank.
