Description

Technical Field

[0001] The present invention relates to the technical field of groundwater treatment, and in particular to a recharge tank. Background Art

[0002] A recharge tank is a facility used for groundwater recharge, usually used for purposes such as controlling groundwater levels, preventing ground subsidence, and improving groundwater quality. The recharge tank can be implemented through recharge wells, recharge devices, etc., to re-inject surface water or treated water into the ground to replenish groundwater reserves or improve groundwater quality. More importantly, when recharging water, the recharge tank can treat the water and optimize the water quality of the recharge water source. By using water quality treatment technology, the types of recharge water sources can be increased, and the quality of recharge water can be optimized. For groundwater with excessively high salt content or other harmful substances, the groundwater quality can be gradually improved by recharging high-quality water. In the process of utilizing geothermal resources, the recharge tank can re-inject used geothermal water into the ground to achieve sustainable utilization of geothermal resources.

[0003] After daily use of groundwater, the amount of groundwater decreases. During recharge, clean water is injected into the groundwater through a water pump to raise the groundwater level. The traditional way of recharge requires equipment matched with the recharge tank to filter the water.

[0012] The working principle and beneficial effects of the present invention are: 1. In the present invention, a conical cylinder and a filter barrel are provided. Water is introduced into the conical cylinder from the outside through a water supply pipe, and the water hits the filter barrel. The water enters the conical cylinder through the filter barrel, and large particles of impurities are filtered by the filter barrel. Since the filter barrel is provided on the side of the conical cylinder, the water rotates in the conical cylinder with the help of the potential energy of motion after passing through the filter barrel, forming a vortex and entering the upper part of the tank body through the liquid inlet. At this time, the gas in the water will be separated from the water when the water rotates along the inner wall of the conical cylinder, and is located in the center of the conical cylinder. Since the water is continuously fed into the recharging tank body, the internal pressure gradually increases. When the air pressure is relatively high, the gas can leave the conical cylinder through the exhaust valve.

When the aeration mechanism injects gas into the water, the excess bubbles float to the center of the partition baffle and surround the water pipe. Since the through hole of the water pipe is set on the side, the bubbles can be prevented from entering the upper part of the tank body through the water pipe. The gas gathered in the center of the partition baffle can be discharged through the exhaust pipe and the exhaust valve. 3. In the present invention, a water cap and a water through hole are provided. When water passes through the water through hole, it passes through the water cap, and the air injection hole on the water cap injects air into the water, so that the water with gas moves toward the liquid outlet, so that the gas in the water is separated when filtering in order to improve the filtering effect and protect the filtering equipment, and then the gas is injected to increase the content of dissolved oxygen in the water, and the gas injection does not affect the filtering; 4. In the present invention, by setting up a filtering and exhausting mechanism, the water can be initially filtered and the gas in the water can be removed while maintaining the water flow rate. By setting up an aeration mechanism, the water can be fully injected with gas. The gas needs to pass through the water holes, but it must come into contact with the bubbles when passing through the water holes. By setting up a partition baffle, the filtering in the upper part of the tank body and the gas injection in the lower part of the tank body can be prevented from affecting each other.

Natural material filter material is provided in the filter material layer 17. Water is filtered through the filter material layer. After passing through the conical cylinder 9, the water enters the upper part 4 of the tank body. The water is filtered through the filter material layer 17. The filtered water flows downward and flows downward through the water pipe 18. The natural material filter material uses natural material filter materials such as activated carbon and quartz sand. A variety of filter materials can be used in combination, and different combinations can play different roles. On the one hand, the cleanliness of the water re-injected into the ground is guaranteed. On the other hand, the use of natural filter materials can imitate the natural filtering method of water underground, which is more suitable for re-injection into the ground.

[0021] like Figure 4~Figure 7 As shown, the partition baffle 3 is set to be conical, and a water pipe 18 is set in the center of the partition baffle 3. The water pipe 18 protrudes on the partition baffle 3 toward the upper part 4 of the tank body.
