Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a hydraulic automatic aeration filter. Background Art

[0002] The principle of hydraulic automatic aeration filter is to simulate the objective self-purification phenomenon of water bodies in nature as a theoretical basis, and integrate a variety of advanced water treatment technologies to develop a new type of water treatment equipment. The specific principle is as follows: First, the water to be filtered enters the aeration and dissolved oxygen tank from the water inlet pipe for aeration and dissolved oxygen, and then the water will be dispersed into four fine filter tanks and dispersed into the muddy water area by the baffle, and then enter the water collection area from the muddy water area through the filter material layer, the support layer, and the mesh plate. Suspended matter and other turbid substances in the raw water are intercepted and attached to the surface and inside of the filter material layer, and the water entering the water collection area is the filtered clean water. Under the action of the liquid level difference before and after the filtration or the pressure of the raw water, the clean water enters the clean water area from the bottom to the top along several flushing and clean water pipes from the water collection area, and then overflows from the clean water area into the water collection tank at the top, flows along the water collection tank to the outlet pipe, and flows out of the aeration filter by gravity.

[0003] For example, the utility model patent with authorization announcement number CN203144220U discloses a gravity-type hydraulic aeration fine filter, which includes an aeration and dissolved oxygen tank and four fine filter tanks arranged around the lower end of the aeration and dissolved oxygen tank. The aeration and dissolved oxygen tank is provided with an inlet distribution tank, an aeration and dissolved oxygen chamber and an aeration tank. The upper end of the aeration tank is connected to the atmosphere, and the lower end of the aeration tank is separated from the inlet distribution tank and the aeration and dissolved oxygen chamber by an aeration strip. An inlet pipe is connected to the side of the inlet distribution tank. The principle is that the water coming in from the inlet pipe overflows from the upper part of the inlet distribution tank and enters the aeration and dissolved oxygen chamber through the diversion of the aeration strip. Its shortcoming is that when the water inlet pipe transports the water to be filtered into the aeration and dissolved oxygen tank, the water passes through the downhole immediately under the action of gravity after being diverted by the aeration strip and then enters the fine filter tank, so that the water flow is in contact with the air for a short time. The water is not in contact with the air sufficiently and flows downward under the action of gravity, which will cause insufficient dissolved oxygen content in the water. Summary of the invention

[0004] The utility model aims to solve the problem that the contact time between water flow and air in the hydraulic automatic aeration filter in the prior art is short, the contact between water and air is insufficient, and the content of dissolved oxygen in water is insufficient, and a hydraulic automatic aeration filter is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A hydraulic automatic aeration filter comprises an aeration and dissolved oxygen tank, which comprises a tank body and a top cover. A water inlet pipe is passed through one side of the tank body. The part of the water inlet pipe located in the tank body is connected with a transition pipe. A water distribution plate is arranged below the transition pipe. A rotating assembly is arranged in the transition pipe. The rotating assembly comprises a rotating shaft and a spiral blade arranged at the bottom end of the rotating shaft. A water spray pipe is arranged on the rotating shaft. The water spray pipe is rotatably connected to the water inlet pipe, and a plurality of water outlet holes are opened on the water spray pipe.

[0007] In some embodiments, the water spray pipe is a T-shaped pipe, which includes a vertical portion and a horizontal portion located at the top of the vertical portion, and multiple water outlet holes are distributed on the horizontal portion. The vertical portion is mounted on the top of the water inlet pipe, and the rotating shaft passes through the vertical portion and is fixedly connected to the horizontal portion. The water spray pipe is passively rotated under the driving action of the spiral blades.

[0008] In some embodiments, blocking covers are respectively provided at both ends of the transverse portion.

[0009] In some embodiments, the water diversion tray is movably mounted on the rotating shaft, the upper surface of the water diversion tray is a conical surface, a through hole is opened in the middle of the water diversion tray, the part of the water inlet pipe located in the box body passes through the through hole, and a plurality of water drop holes are also opened on the water diversion tray.

[0010] In some embodiments, a support frame is provided in the transition tube, and the support frame includes a circular ring and a plurality of connecting rods evenly distributed on the outer circumference of the circular ring. The circular ring is mounted on the rotating shaft, one end of the connecting rod is connected to the circular ring, and the other end of the connecting rod is connected to the inner wall of the transition tube, and the support frame provides support for the rotating shaft.

[0011] In some embodiments, the top cover is disposed at the top of the box body, and the top end of the rotating shaft passes through the water inlet pipe and is rotatably disposed on the top cover.

[0012] In some embodiments, the top cover is provided with a plurality of ventilation holes extending vertically therethrough, so that the box body is connected to the atmosphere.

[0013] Compared with the prior art, the utility model provides a hydraulic automatic aeration filter having the following beneficial effects.

[0014] The utility model provides a rotating component and a water spray pipe. When the water flow impacts one side of the spiral blade, the spiral blade continuously pushes the water backwards, generating a circular rotation force on the spiral blade. At this time, the spiral blade drives the rotating shaft to rotate, and the water spray pipe rotates passively. Then, the water flows into the inner side of the water spray pipe along with the water flow and is discharged through a plurality of water outlet holes. At the same time, under the rotation of the water spray pipe, the water flow is dispersed and evenly sprayed on the top of the water separation plate, and then falls through the water drop holes into the fine filter tank to complete the subsequent process. In this process, the dispersed water flow enters the box body for a short stay, and the water falling from the water drop holes of the water separation plate forms a rain curtain effect, which further dissolves oxygen. The combination of the two can increase the contact area and time between water and air, thereby increasing the dissolved oxygen content in the water.

[0015] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model can dissolve more oxygen into the water by arranging a rotating component, a water spray pipe and a water distribution plate, thereby enhancing the aeration effect.

[0016] Other advantages, objectives and features of the present invention will be described in the following description to some extent; and will be apparent to those skilled in the art based on the following examination and study to some extent; or, may be taught from the practice of the present invention.
