Description

Technical Field

[0001] This utility model belongs to the technical field of quartz sand filter, specifically a quartz sand filter. Background Technology

[0002] A quartz sand filter, scientifically known as a shallow media filter, uses quartz sand as the filter medium. Under certain pressure, water with high turbidity is filtered through a layer of granular or non-granular quartz sand of a certain thickness. This effectively traps and removes suspended solids, organic matter, colloidal particles, microorganisms, chlorine, odors, and some heavy metal ions from the water, ultimately achieving the effect of reducing water turbidity and purifying water quality. However, after a certain period of time, due to the presence of some large particles of impurities in the wastewater, these large particles will adhere to the quartz sand under the impact of water pressure. Backwashing is required to remove the impurities attached to the quartz sand, but backwashing cannot effectively remove the impurities. Therefore, the quartz sand needs to be removed for cleaning. However, common devices are not convenient for removing the internal quartz sand or replacing it. Furthermore, if impurities are not cleaned in time, the filtration effect of the quartz sand will be seriously affected. Therefore, this application proposes a quartz sand filter.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figure 1-6 The present invention includes a main body 1, with a first cavity 2 inside the main body 1, a second cavity 3 communicating with the first cavity 2 at the top of the main body 1, a square second opening 11 communicating with the first cavity 2 at the left side of the main body 1, and a circular first opening 10 communicating with the first cavity 2 at the right side of the main body 1. A quartz sand filter box 12 is fixedly installed at the top of the first cavity 2, a discharge pipe 15 is fixedly connected to the left side of the quartz sand filter box 12 and exits through the second opening 11 on the left side of the main body 1, and an inlet pipe 14 is fixedly connected to the right side of the quartz sand filter box 12 and exits through the first opening 10 on the right side of the main body 1. A liftable filter assembly is provided in the second cavity 3.

[0021] like Figure 2 As shown, the first cavity 2 is set in the shape of a square column, and the second cavity 3 is set in the shape of a cylinder. The diameter of the second cavity 3 gradually decreases from top to bottom, and the diameter of the bottom opening of the second cavity 3 is smaller than the side length of the cross section of the first cavity 2.

[0022] like Figure 3 and Figure 6As shown, the filter assembly includes a ring 4 and a filter funnel 5. The outer wall of the ring 4 can fit against the inner wall of the lower half of the second cavity 3. The filter funnel 5 is located inside the ring 4, with its bottom closed and its top fitted against the inner wall of the ring 4. The lower half of the filter funnel 5 is configured as a filter screen. When sewage enters the second cavity 3, all the sewage will enter the filter funnel 5 between the rings 4. The filter funnel 5 can intercept larger impurities in the sewage, thus preventing a large number of impurities from adhering to the quartz sand. The sewage that has passed through the filter funnel 5 will enter the quartz sand filter box 12, and then the quartz sand layer in the quartz sand filter box 12 can perform more effective filtration of the sewage.

[0023] like Figure 1 and Figure 5 As shown, storage slots 7 are provided at the four corners of the top of the main body 1. A hydraulic rod 8 is fixedly installed in each storage slot 7. Four connecting rods 6 are evenly and fixedly installed on the top of the ring 4. A connecting plate 9 is fixedly connected between the four connecting rods 6 and the telescopic ends of the corresponding hydraulic rods 8. By controlling the four hydraulic rods 8 to extend simultaneously, the ring 4 can be moved upward in the second cavity 3 at the top of the main body 1 through the connecting plate 9 and the connecting rod 6, so as to remove the filter funnel 5 between the rings 4.

[0024] like Figure 4 and Figure 6 As shown, the top and bottom of the quartz sand filter box 12 are both open, and filter plates 13 are fixedly installed at the bottom opening of the quartz sand filter box 12. The filter plates 13 are set in an inclined state, and the lower end of the filter plate 13 is flush with the bottom of the second port 11. The connection between the feed pipe 14 and the first port 10 is sealed by welding, and the connection between the discharge pipe 15 and the second port 11 is sealed by welding. The openings of the discharge pipe 15 and the feed pipe 14 are both threaded with sealing caps. Under the action of the filter plates 13 at the bottom opening of the quartz sand filter box 12, the quartz sand enters the quartz sand filter box 12 and is stored inside. The sealing caps set at the openings of the discharge pipe 15 and the feed pipe 14 can prevent the leakage of quartz sand.

[0025] like Figure 1 and Figure 6 As shown, the bottom of the first cavity 2 is set as a slope, and a third opening 16 is opened at the bottom of the main body 1. A drain pipe 17 is fixedly connected at the third opening 16. Support legs 18 are fixedly installed at the four corners of the bottom of the main body 1. The filtered water can be discharged through the drain pipe 17, while the four support legs 18 can support the main body 1.

[0026] When using the device to filter wastewater, the wastewater is injected into the second cavity 3 at the top of the main body 1. The filter funnel 5 between the rings 4 effectively intercepts large particles of impurities in the wastewater, which remain in the filter funnel 5. The wastewater passing through the filter funnel 5 then enters the quartz sand filter box 12. The quartz sand layer in the quartz sand filter box 12 then filters the wastewater more effectively. Finally, the filtered wastewater is discharged from the drain pipe 17. When cleaning up the intercepted large particles of impurities, the hydraulic rod 8 is controlled to push the connecting plate 9 upward. The connecting plate 9 drives the connecting rod 6, which in turn moves the ring 4 upward. After the ring 4 moves out of the second cavity 3, the filter funnel 5 inside can be taken out, and then the impurities in the filter funnel 5 can be cleaned. When replacing the quartz sand in the quartz sand filter box 12, open the sealing caps at the openings of the feed pipe 14 and the discharge pipe 15 at the same time, and inject water into the interior through the feed pipe 14. In this way, the quartz sand will slide along the inclined surface of the bottom filter plate 13 and finally be discharged from the discharge pipe 15. Then close the sealing cap at the opening of the discharge pipe 15 and add quartz sand again through the feed pipe 14.
