The tank body is a pressure-bearing steel tank body.

The beneficial effects of the utility model are:

Compared with the prior art, in the high-efficiency water purification filter provided by the utility model, the raw water is firstly filtered through the water distributor in the tank body, and then the small particle size suspended matter in the water is removed through the polymer filter material in the filter bed. In the filtration process, compared with the existing water purifiers or filters, the utility model has the advantages of good filtration effect, high efficiency and low energy consumption. Strong impact load capacity.

detailed description

Below in conjunction with accompanying drawing, the technical scheme of the present utility model will be further described, but the required protection scope is not limited to the description;

As shown in Figure 1, the high-efficiency water purification filter provided by the utility model includes a tank body 3, and the tank body 3 is fixed on the foundation platform 21 by a four-corner bracket 9 installed at the bottom thereof, and the tank body 3 is from top to bottom. Water chamber 15, filter chamber 16 and water outlet chamber 14, the bottom end of the water inlet chamber 15 is a funnel-shaped water distributor 5, the middle part of the bottom end of the water distributor 5 is provided with a water inlet 17, and the water inlet 17 is connected with the tank body 3 The external recoil drain pipe 2 is connected; the filter chamber 16 is filled with a filter bed 7, and the filter bed 7 is fixed on the bottom of the filter chamber 16 through the filter bed support 8 at the bottom; the middle part of the bottom of the outlet chamber 14 is provided There is a discharge port 22, and the downstream of the discharge port 22 is connected with an outlet pipe 12, and the outlet pipe 12 is connected with a recoil water pipe 11; the recoil drain pipe 2 is connected with a water inlet pipe 1, and the outlet end of the recoil drain pipe 2 is placed In the drainage ditch 13 on the side of the foundation platform 21.

In order to facilitate the free switching of the utility model in the two states of normal filtration and backwashing, the water inlet pipe 1, the backwash drain pipe 2 and the water outlet pipe 12 are respectively equipped with a valve A18, a valve B19 and a valve C20.

The top of the water inlet chamber 15 is provided with an exhaust valve 4, and the water outlet 22 is connected with a recoil air pipe 10, that is, adding recoil air washing on the basis of recoil washing, which can effectively improve the stirring of the filter material, Improve the backwash effect.

The horizontal section of the water inlet pipe 1 is connected to the vertical pipe section of the recoil drain pipe 2 to ensure that dirt will not enter the water inlet pipe 1 during recoil.

A support filter cap 23 is provided between the filter bed 7 and the filter bed support 8, which is used to retain the small particle size suspended solids in the water body during filtration, and the support filter cap 23 protects the filter material during filtration and prevents the filter from recoiling. To the role of water distribution and gas distribution.

In order to ensure that the utility model has sufficient processing capacity, the tank body 2 has a diameter of 3m and a height of 5m.

In order to ensure that the tank body 3 has sufficient strength, the tank body 3 is a pressure-bearing steel tank body.

When in use, the raw water enters the water inlet 17 at the bottom of the water inlet chamber 15 at the top of the tank body 3 through the water inlet pipe 1. The raw water is initially filtered through the funnel-shaped water distributor 5, and then the water body enters the filter bed 7 downwards and passes through the filter bed. After the bed 7 removes the remaining small-size suspended solids in the water, the filtration process is completed. After the filtration, the water is basically free of impurities, and then enters the outlet pipe 12 through the outlet chamber 14 at the bottom of the tank body 3 and flows into the high-level pool (not shown in the figure). , and finally enter the urban water supply pipeline from the high-level pool to supply water to the city. When the dirt holding capacity of the filter bed tends to be saturated, the automatic control system performs gas-water mixed backwashing on the tank 3 according to the signal fed back by the pressure sensor (not shown in the figure), closes the valve A18 on the water inlet pipe 1, and opens the valve B19 And valve C20, open the solenoid valve (shown in the figure) of recoil air pipe 10 and recoil water pipe 11, feed high-pressure gas, water mixture in tank body 3. At this time, the supporting filter cap 23 at the bottom of the filter bed 7 plays the role of water distribution and air distribution, so that the recoil pressure of the entire filter bed 7 is balanced and uniform, ensuring that there is no dead angle in the recoil, and the polymer filter material is in the filter chamber 16. Vertical high-speed spinning body, the centrifugal force generated by high-speed rotation easily shakes off the dirt attached to the filter material, and the dirt enters the water inlet chamber 15 from the hole of the water distributor 5 with the pressure fluid of the recoil, and finally enters the recoil The drain pipe 2 discharges into the gutter 13 .
