Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically a sand filter tank with good purification effect. Background Technology

[0002] Sand filters play a crucial role in numerous fields, including industrial production and water treatment. Existing quartz sand filtration technologies largely rely on backwashing to clean the filter media. During backwashing, impurities in the quartz sand are removed primarily by the impact of the returning water. However, this single-mode backwashing has drawbacks.

[0003] Because relying solely on water flow has limited cleaning effectiveness, it is often insufficient to completely remove impurities adsorbed in the crevices and on the surface of quartz sand in a single pass. To achieve a relatively ideal cleaning effect, it is necessary to extend the backwashing time. This not only consumes a large amount of water resources, undoubtedly increasing the resource burden in the current context of increasingly precious water resources, but also means that the entire filtration system needs to be interrupted for an extended period. The suspension of filtration forces the production process to stop, making it impossible to continuously and stably supply filtered, qualified water or other fluids, severely impacting overall production efficiency and capacity.

[0004] Therefore, there is an urgent need for a sand filter tank with good purification effect. Summary of the Invention

[0029] The tank body 1 is connected to a first partition plate 2, a second partition plate 14, and a support plate 25 distributed from top to bottom.

The bottom side of the filter chamber 8 is connected to a packing mesh basket 10 through a spring column 11. The outside of the filter chamber 8 is equipped with a sewage pump 9 and a motor 12 connected to the tank body 1. The sewage pump 9 is connected to the top space of the filter chamber 8 through a pipe. The drive end of the motor 12 is connected to a cam 13 corresponding to the bottom of the packing mesh basket 10.

[0031] The bottom of the filter chamber 8 is connected to a branch pipe 16 that passes through the second partition plate 14 and the support plate 25 in sequence, and the branch pipe 16 is connected to a branch outlet valve 15.

[0032] A flushing pump 26 is connected to the top of the support plate 25. A flushing pipe 24 that penetrates the support plate 25 is connected to the inlet of the flushing pump 26. A flushing Y-shaped pipe 27 that is inserted into the two sets of filter chambers 8 is connected to the outlet of the flushing pump 26. A flushing valve 28 is connected to each branch end of the flushing Y-shaped pipe 27.

[0033] A set of support rods 17 are connected to a control switch 21, a controller 22, an electric push rod 6, a sewage pump 9, a motor 12, a branch outlet valve 15, a main outlet valve 18, a controller 22, a flushing pump 26, and a flushing valve 28, which are respectively connected to an external power source through the control switch 21.

[0034] Working principle

[0035] During normal filtration, the water to be filtered enters the tank 1 through the inlet pipe 4, passes through two inlet holes 3, two packing mesh baskets 10, and two branch outlet valves 15, and is discharged from the main outlet valve 18. When the packing mesh basket 10 is backwashed, a set of inlet holes 3 is blocked by pressing down the block 7 through the corresponding electric push rod 6, and at the same time, the branch outlet valve 15 below the blocked filter chamber 8 is closed.

[0036] During backwashing, the flushing pump 26 is started, and the sewage pump 9, motor 12, and flushing valve 28 corresponding to the blocked filter chamber 8 are turned on. The flushing pump 26 draws the filtered water from the bottom of the tank 1 and uses the water to flush and clean the packing mesh basket 10. At the same time, the motor 12 below the cleaned packing mesh basket 10 drives the cam 13 to rotate. The cam 13 collides with the packing mesh basket 10 and vibrates under the action of the spring column 11, which facilitates the removal of debris, ensures the cleaning quality of the packing mesh basket 10, and improves the filtration and purification effect. The cleaned sewage is discharged from the tank 1 through the sewage pump 9.

[0037] At the same time, another packing mesh basket 10 performs normal filtration work to ensure the normal operation of filtration and improve the efficiency of filtration.

[0038] During backwashing, the main outlet valve 18 is closed, the filtered water is stored in the tank 1, the flushing pump 26 is activated, and the flushing valve 28 is opened. The filtered water stored in the tank 1 is used for backwashing, which effectively saves water resources. Example 1
