Anti-blocking and sand removing type water taking purifier

Abstract

The invention discloses an anti-blocking and sand removing type water taking purifier. The purifier includes a body; umbrella-shaped inclined plates are mounted on both sides of the body; cylindricalguide plates are arranged below the umbrella-shaped inclined plates; a water collecting pipe is arranged at the middle of the umbrella-shaped inclined plates; a water outlet is disposed at the lower part of the water collecting pipe through a water outlet pipe; and the bottoms of the cylindrical guide plates are equipped with a water inlet. The anti-blocking and sand removing type water taking purifier provided by the invention is added with the guide plates at the equipment inlet to reduce disturbance to bottom water and also have certain guide effect on inflow water, thus ensuring the laminar flow state of water; and a conical structure at the upper part of the device is changed to a truncated cone structure, dead angle, short flow and other circumstances can be avoided at the top, and normal operation of the equipment is guaranteed.

Description

technical field [0001] The invention relates to a water purifier, in particular to an anti-clogging and sand-removing water purifier, which belongs to the technical field of water purifiers. Background technique [0002] Existing anti-blocking and desanding type water intake water purifiers, such as figure 1 As shown, it includes a main body 1; the top of the main body 1 is provided with a conical upper cover 2; both sides of the main body 1 are provided with an annular sloping plate 3; the bottom of the annular sloping plate 3 is provided with an annular sand discharge port 4; A cylindrical grid 5 is installed on the outer side of the annular sloping plate 3; a water collecting tube 6 is installed on the top thereof in the middle of the annular sloping plate 3; a water outlet pipe 7 is connected below the water collecting tube 6; the inclination angle of the annular sloping plate 3 is is 60°, and the plate spacing is 30mm; the fluid flow state in this equipment is relative...

[0002] Existing anti-blocking and desanding type water intake water purifiers, such as figure 1 As shown, it includes a main body 1; the top of the main body 1 is provided with a conical upper cover 2; both sides of the main body 1 are provided with an annular sloping plate 3; the bottom of the annular sloping plate 3 is provided with an annular sand discharge port 4; A cylindrical grid 5 is installed on the outer side of the annular sloping plate 3; a water collecting tube 6 is installed on the top thereof in the middle of the annular sloping plate 3; a water outlet pipe 7 is connected below the water collecting tube 6; the inclination angle of the annular sloping plate 3 is is 60°, and the plate spacing is 30mm; the fluid flow state in this equipment is relatively complex, and the flow state at different places is quite different. Water, the sand content of the water intake sample increases, and the effluent cannot meet the requirements of the subsequent process; the influent water directly enters the inclined plate for sedimentation, and the speed of the rising water flow continues to increase, which is not conducive to the precipitation of particulate matter; start from the bottom of the water intake head , as the height increases, the flow velocity of the fluid between the sloping plates decreases continuously, and the flow velocity at the top of the equipment is extremely low, which not only wastes the space, but also makes it difficult to ensure the sealing of the top during long-term use, so that the equipment cannot operate normally. ; The sloping plate in the equipment should not be installed and fixed, too many fixing devices will further affect the flow state of the fluid
