Description

Technical Field

[0001] This utility model relates to the field of water filtration equipment, specifically to a quartz sand filtration device. Background Technology

[0002] In the field of water treatment, quartz sand filtration equipment is widely used in industrial production, drinking water purification, and wastewater treatment. Quartz sand, due to its excellent chemical stability and high mechanical strength, is a common medium for filtering suspended impurities and colloidal substances in water. However, existing quartz sand filtration equipment has many shortcomings in practical use. Some equipment has an unreasonable structural design, resulting in low filtration efficiency and an inability to effectively remove suspended solids from the water, failing to meet increasingly stringent water quality standards. At the same time, the backwashing function of traditional equipment is inadequate, and the backwashing process is complex, failing to fully wash away the impurities trapped inside the quartz sand, which not only affects the service life of the quartz sand but also reduces the filtration effect of the equipment. Furthermore, the connection methods of the various components are not flexible enough, which is not conducive to the installation, maintenance, and replacement of the equipment, increasing operating costs and difficulty. Therefore, there is an urgent need to develop a quartz sand filtration device with optimized structure, good filtration effect, convenient backwashing, and easy maintenance. Utility Model Content

[0006] According to the present invention, a quartz sand filtration device is characterized in that the inlet pipe, outlet pipe, drain outlet, and inner pipe are all stainless steel pipes.

[0007] According to the present invention, a quartz sand filtration device is characterized in that the filter cylinder is a stainless steel cylinder, and its upper and lower ends are respectively provided with external threaded connection interfaces for movably connecting with the upper fixed seat and the base.

[0008] This utility model has the following advantages: Through its unique structural design and workflow, this quartz sand filtration equipment exhibits significant advantages over traditional equipment.

[0009] Firstly, the equipment adopts a filtration method that combines an inlet pipe and an inner pipe. During the filtration process, water enters the lower layer from the upper layer of quartz sand through the inlet pipe and the inner pipe, allowing the water flow to fully contact the quartz sand. This effectively prolongs the contact time between the water and the quartz sand, greatly improving the adsorption and decomposition efficiency of the quartz sand on suspended pollutants in the water, thereby enhancing the overall filtration effect and ensuring that the purified water quality reaches a higher standard.

[0010] Secondly, regarding the backwashing function, through the reasonable setting of branch pipes, inlet pipes, drain outlets, and corresponding valves, the first valve is opened, the second valve is closed, and the third valve is opened during backwashing. Water enters the inner cavity of the filter cylinder through the inlet pipe and branch pipes to thoroughly wash the quartz sand. This can completely remove the dirt trapped in the quartz sand and discharge it smoothly through the drain outlet. This not only improves the backwashing efficiency but also effectively protects the quartz sand, extends its service life, and reduces equipment operating costs.

[0011] Thirdly, the filter cylinder body of the equipment is connected to the base and the upper fixed seat in a detachable and movable manner. The filter cylinder body is equipped with connection interfaces with external threads at the upper and lower ends. The water inlet pipe, water outlet pipe, sewage outlet and inner pipe are all made of stainless steel. This design facilitates the installation, disassembly and maintenance of various parts of the equipment, and makes it convenient for users to operate quickly when the equipment malfunctions or needs to replace parts. It significantly reduces the cost of use and the difficulty of operation, and improves the practicality and applicability of the equipment. Attached Figure Description

Figures 1-4 As shown, the device can be implemented as follows: The device comprises a filter cylinder 1 and a cavity filled with quartz sand 2. It also includes a base 3, an upper fixing seat 4, an inlet pipe 5, an outlet pipe 6, a drain port 7, and an inner pipe 8. The base 3 is located at the bottom of the filter cylinder 1, and the two are detachably connected. The upper fixing seat 4 is located at the top of the filter cylinder 1, and the two are detachably connected. The inlet pipe 5, outlet pipe 6, and drain port 7 are respectively fixed to the upper fixing seat 4. Pipe 5 has a branch pipe 9 that communicates with the inner cavity of the filter tank 1. The branch pipe 9 is used to introduce water into the filter tank 1 during backwashing. A first valve 10 is provided on the branch pipe 9. The other end of the water inlet pipe 5 is connected to the inner pipe 8, and a second valve 11 is provided between the inner pipe 8 and the water inlet pipe 5. The drain outlet 7 is connected to the inner pipe 8, and a third valve 12 is provided on the drain outlet 7. The drain outlet 7 is used to discharge dirt during backwashing. The inner pipe 8 is used to discharge dirt during backwashing and to deliver water to the bottom of the quartz sand 2 during filtration.

[0018] In this application, the inlet pipe 5, the outlet pipe 6, the drain outlet 7, and the inner pipe 8 are all stainless steel pipes.

[0019] The filter cylinder 1 is a stainless steel cylinder, with external threaded connection interfaces 13 at its upper and lower ends, which are used to achieve movable connection with the upper fixed seat 4 and the base 3.

[0020] Backwashing process: Open the first valve 10, close the second valve 11, open the third valve 12, and water enters the inner cavity of the filter cylinder 1 through the inlet pipe 5 and the branch pipe 9. The water is washed away by the quartz sand to remove the dirt filtered in the quartz sand and discharged through the drain port 7.

[0021] Filtration process: Close the first valve 10 and open the second valve 11. Water enters the sand tank through the inlet pipe 5 and the inner pipe 8. It enters from the upper layer of quartz sand to the lower layer through the inner pipe 8 and comes out from the lower layer. The suspended dirt in the water is adsorbed and decomposed, so that the purified water flows out from the bottom to the top through the outlet pipe 6.

[0022] The specific implementation process of this application is described below;

[0023] I. Equipment Installation: Connect the threaded interfaces 13 at the upper and lower ends of the filter cylinder 1 to the base 3 and the upper fixing seat 4 respectively, completing the detachable installation of the filter cylinder with the base and upper fixing seat, ensuring a secure connection. Fix the inlet pipe 5, outlet pipe 6, and drain port 7 to their corresponding installation positions on the upper fixing seat 4, ensuring tight connections and no risk of leakage.

[0024] II. Filtration Process: Close the first valve 10 to prevent water from entering the filter tank 1 from the branch pipe 9. Open the second valve 11 to connect the inlet pipe 5 with the inner pipe 8. The water to be filtered flows in through the inlet pipe 5 and enters from the upper layer of quartz sand 2 through the inner pipe 8. Under the action of gravity, it passes through the quartz sand layer, and the suspended impurities in the water are adsorbed and decomposed by the quartz sand. The purified water flows out from the lower layer of quartz sand 2 and is discharged from the bottom up through the outlet pipe 6, completing the filtration process.

[0025] III. Backwashing Process: Close the second valve 11 to block the passage between the inlet pipe 5 and the inner pipe 8. Open the first valve 10 to connect the inlet pipe 5 and the branch pipe 9, and simultaneously open the third valve 12. Water flows through the inlet pipe 5 and the branch pipe 9 into the inner cavity of the filter tank 1, performing a reverse flushing of the quartz sand 2. During the flushing process, the impurities trapped in the quartz sand are washed down by the water flow and discharged through the drain port 7 via the inner pipe 8, effectively removing impurities from the quartz sand and restoring its filtration performance.
