[0002] Raw water, as an untreated water resource in nature, contains various impurities, suspended matter, organic matter, colloids and microorganisms. Therefore, filtration equipment is needed to filter the raw water to remove impurities and pollutants.

[0003] At present, when filtering raw water, as in the patent with the prior art authorization announcement number CN220642672U, the utility model belongs to the field of raw water purification, especially the raw water high-efficiency filtering device. The existing filtering device adopts an isolation net to filter and block particles, but the particles easily clog the isolation net, resulting in poor filtration. The raw water is simply filtered and adsorbed without sterilizing the raw water, resulting in the problem of incomplete treatment. The following scheme is proposed, which includes a base, the top of the base is fixedly connected to a treatment box, the treatment box is provided with a sealing door, and the top of the treatment box is fixedly connected to an inlet pipe for water intake.

[0004] However, during the use of the device, it was found that the device is not convenient for automatically cleaning and discharging the dirt filtered by the filter plate, which increases the complexity of regular cleaning and maintenance of the inside of the device by personnel and reduces the convenience of use. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a raw water filtration device which improves the convenience of internal automatic periodic cleaning and maintenance, reduces the complexity of manual cleaning and maintenance by personnel, and improves the cleaning and maintenance efficiency.

[0006] The utility model discloses a raw water filtering device, comprising a box body and a first filter screen, wherein the first filter screen is mounted on the inner wall of the box body; further comprising a storage device, a siphon device, an absorption cover, a water inlet pipe and a drain pipe, wherein the absorption cover is mounted on the inner wall of the box body, and the absorption cover is arranged above the first filter screen, the output end of the water inlet pipe is communicated with the inside of the absorption cover, the drain pipe is arranged at the lower part of the outer wall of the box body, the drain pipe is communicated with the storage device, the storage device is used to collect water, the top end of the absorption cover is communicated with the siphon device, and the siphon device is used to suck the inside of the absorption cover; the raw water is transported to the absorption cover through the water inlet pipe After that, the raw water passes through the first filter and flows downward and is discharged from the drain pipe. When the drain pipe discharges the filtered raw water, part of the raw water enters the storage device for storage. The dirt in the raw water is continuously deposited on the top of the first filter, causing the water permeability of the first filter to decrease. At this time, the water inlet speed of the water inlet pipe remains unchanged, causing the water level in the box to rise. After the water level rises, it flows into the siphon device through the absorption cover, and the siphon device is triggered to suck the absorption cover, so that the water in the storage device backwashes and cleans the first filter, thereby improving the convenience of automatic regular cleaning and maintenance inside the equipment.

When the water level reaches the highest point on the right part of the siphon, the water in the siphon flows downward through the diverter pipe and enters the interior of the delivery box. When the water flows downward through the diverter pipe and is discharged, the air in the left part of the siphon is extracted. At this time, the water in the delivery box flows back to the left part of the siphon. When the siphon is full of water, the siphon generates siphoning, so that the siphon draws the water in the box through the absorption cover. After the water flows in the opposite direction, the first filter is backwashed, thereby improving the convenience of automatic cleaning of the first filter.

[0011] Preferably, a second filter is also included, which is connected to the air inlet of the one-way inlet valve; when outdoor air enters the collection box through the one-way inlet valve, the air is filtered by the second filter, thereby reducing the dirt in the outdoor air from entering the collection box.

A vent is provided at the top of the conveying box 6. The cover body 11 is mounted on the vent at the top of the conveying box 6. The baffle 7 is mounted on the inner wall of the conveying box 6. The discharge valve 8 is connected and arranged on the outer wall of the conveying box 6. The input end of the siphon pipe 9 is connected with the top of the absorption cover 3. The output end of the siphon pipe 9 extends into the interior of the conveying box 6. The input end of the shunt pipe 10 is connected and arranged on the outer wall of the siphon pipe 9. The output end of the shunt pipe 10 extends into the interior of the conveying box 6, and the output ends of the siphon pipe 9 and the shunt pipe 10 are both immersed in the water in the conveying box 6.

[0023] In this embodiment, raw water is transported to the interior of the absorption hood 3 through the water inlet pipe 4, and then the raw water passes through the first filter screen 2 and flows downward and is discharged from the drain pipe 5. When the drain pipe 5 discharges the filtered raw water, part of the raw water enters the storage device for storage. The dirt in the raw water is continuously deposited on the top of the first filter screen 2, causing the water permeability of the first filter screen 2 to decrease. At this time, the water inlet speed of the water inlet pipe 4 remains unchanged, causing the water level in the box body 1 to rise. After the water level rises, it flows into the siphon device through the absorption hood 3, and the absorption hood 3 is sucked by triggering the siphon device, so that the water in the storage device backwashes and cleans the first filter screen 2, thereby improving the convenience of automatic regular cleaning and maintenance inside the equipment.

When the water level reaches the highest point on the right part of the siphon tube 9, the water in the siphon tube 9 flows downward through the shunt tube 10 into the inside of the delivery box 6. When the water flows downward through the shunt tube 10 and is discharged, the air in the left part of the siphon tube 9 is extracted. At this time, the water in the delivery box 6 flows back upward to the left part of the siphon tube 9. When the water in the siphon tube 9 is full, the siphon tube 9 generates siphoning, so that the siphon tube 9 extracts the water in the box 1 through the absorption cover 3, and the water flows in the reverse direction.

After the water in the collection box 13 is reduced, the outdoor air enters the inside of the collection box 13 through the one-way inlet valve 14. When the siphon tube 9 sucks the inside of the box body 1, due to the action of the one-way drain valve 15, the water discharged from the drain pipe 5 will not flow back, thereby improving the convenience of using the equipment.

[0030] The utility model provides a raw water filtering device, which, when working, conveys raw water to the inside of the absorption cover 3 through the water inlet pipe 4, and then the raw water passes through the first filter screen 2 and flows downward and is discharged from the drain pipe 5. When the drain pipe 5 discharges the filtered raw water, part of the raw water enters the storage device for storage, and the dirt in the raw water is continuously deposited on the top of the first filter screen 2, causing the water permeability of the first filter screen 2 to decrease. At this time, the water inlet speed of the water inlet pipe 4 remains unchanged, causing the water level in the box body 1 to rise. After the water level rises, it flows into the siphon device through the absorption cover 3, and the siphon device is triggered to suck the inside of the absorption cover 3, so that the water in the storage device backwashes and cleans the first filter screen 2.
