Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an alkali supply device for a graphite purification wastewater treatment pond. Background Technology

[0002] Graphite purification wastewater mainly originates from the graphite purification workshop. This process generates wastewater containing various pollutants, including acid recovery wastewater, washing wastewater, and exhaust gas treatment wastewater. This wastewater contains high levels of salt, low pH, and large amounts of fluoride ions, therefore it cannot be directly discharged and requires specific treatment methods to reduce its environmental impact. Currently, the wastewater is typically first poured into a treatment tank, and then alkali is added to the tank through an alkali supply device to neutralize it, reducing its acidity and bringing the pH to neutral or near-neutral, thus minimizing its environmental impact.

[0003] Chinese Patent Publication No. CN217808897U discloses an alkali supply device for a microcrystalline graphite purification wastewater treatment tank. By setting up a squeezing mechanism inside the alkali storage tank, the alkali in the storage tank is squeezed downward by the vertical movement of the first and second pressure plates, so that the alkali in the storage tank flows rapidly into the drain pipe and into the microcrystalline graphite purification wastewater treatment tank for use, thereby improving the efficiency of alkali supply to the treatment tank.

[0004] While the aforementioned patent accelerates the efficiency of alkali supply, the amount of alkali in the alkali storage tank decreases with use. Alkali can only be added to the storage tank when the first and second pressure plates have risen to their highest positions. This prevents the simultaneous supply of alkali to the treatment tank and the addition of alkali to the storage tank, thus reducing the efficiency of alkali addition and consequently slowing down the wastewater treatment efficiency.
