Technical Field

[0001] The utility model relates to the technical field of dissolved oxygen fine filters, in particular to a hydraulic full-automatic dissolved oxygen fine filter. Background Art

[0002] The hydraulic fully automatic dissolved oxygen fine filter is a water treatment equipment. Its working principle is to rely on the gravity flow of water to make the sewage pass through the dissolved oxygen tank and fine filter tank, and after it is fully in contact with the oxygen in the air, it passes through the filter layer to purify the sewage. It is mainly used in scenes such as swimming pools. The hydraulic fully automatic dissolved oxygen fine filter is often set at the bottom of the pool so that the water in the pool can pass through the filter equipment by gravity. During the treatment process, the aeration effect of the sewage in the dissolved oxygen tank is very important. Sufficient aeration can not only increase the dissolved oxygen content, but also make the gases such as ammonia nitrogen contained in the water volatilize and overflow, thereby removing harmful substances in the water and maintaining the freshness of the water quality.

[0003] The utility model patented fully automatic gravity aeration fine filtration equipment with publication number CN210855646U, after the water inlet pipe sends water to the upper part of the aeration dissolved oxygen tank, uses the water distribution plate to disperse the sewage and make the sewage stay for a short time to increase the adequacy of the contact between sewage and air. However, the sewage stay time is short and the external air flow effect is poor, which affects the improvement of the aeration effect. Utility Model Content

For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] The present invention is further described in detail below in conjunction with the embodiments.

[0030] The specific embodiment of the hydraulic fully automatic dissolved oxygen fine filter provided by the utility model is as follows:

[0031] See also Figure 1-6 The hydraulic fully automatic dissolved oxygen fine filter comprises a dissolved oxygen tank 1, a water inlet pipe 2, a plurality of grids 4 and a rotating shaft 5; the water inlet end of the water inlet pipe 2 is connected to an external pipe, and the external pipe is used to connect to the bottom of the pool water and introduce the pool water. The dissolved oxygen tank 1 is set at a height lower than the pool, and the sewage automatically enters the dissolved oxygen tank 1 by relying on the gravity of the water. The clean water purified by the hydraulic fully automatic dissolved oxygen fine filter is pumped back into the pool by a water pump.

[0032] The water inlet pipe 2 extends upward from the bottom into the dissolved oxygen tank 1, and a plurality of water spray heads 3 are connected to the upper end thereof; in this embodiment, the water inlet pipe 2 extends vertically upward from the bottom center of the dissolved oxygen tank 1 into the dissolved oxygen tank 1, and the upper end thereof extends to the upper part of the dissolved oxygen tank 1. The water spray heads 3 are all arranged horizontally on the side of the upper end of the water inlet pipe 2 and along the radial direction of the water inlet pipe 2, and are evenly distributed around the circumference. The water spray heads 3 are tubular structures and do not affect the discharge of sewage. The upper end of the water inlet pipe 2 is closed. In this way, the sewage passes through the water inlet pipe 2 and is uniformly sprayed out from the water spray heads 3 to the surroundings.

[0033] In this embodiment, the grid 4 is set to six layers. The grid 4 is located between the upper outer side of the water inlet pipe 2 and the dissolved oxygen tank 1, and is located at the lower side of the sprinkler head 3; the sewage sprayed from the sprinkler head 3 falls on the grid 4 and is further dispersed. The sewage gradually passes through each layer of the grid 4 and falls in a dispersed manner. In this process, it is in contact with the air for aeration, thereby achieving a better dissolved oxygen effect.

[0034] Since the upper end of the water inlet pipe 2 is closed, the rotating shaft 5 is vertically arranged and rotatably installed at the center of the upper wall of the water inlet pipe 2, the rotating shaft 5 passes through the upper wall of the water inlet pipe 2, the lower part of the rotating shaft 5 is located inside the water inlet pipe 2, and the upper part is located outside the water inlet pipe 2. In this embodiment, the outer side of the lower part of the rotating shaft 5 located inside the water inlet pipe 2 is installed with a paddle 6, and the outer side of the upper part of the rotating shaft 5 located outside the water inlet pipe 2 is installed with a fan blade 7.

[0035] Specifically, the fan blades 7 are installed in a group evenly distributed around the circumference; the paddle blades 6 are installed in a plurality of groups, each group of paddle blades 6 is evenly distributed around the circumference, and the plurality of paddle blades 6 are evenly distributed along the rotating shaft 5. When sewage flows in the water inlet pipe 2, the paddle blades 6 are driven to rotate, and the paddle blades 6 drive the rotating shaft 5 to rotate, so that the fan blades 7 rotate to drive the air to move vertically, forming a vertical airflow, and the vertical airflow passes through the grid 4, so that the outside air is fully in contact with the dispersed and falling sewage, increasing the amount of dissolved oxygen on the surface of the sewage, thereby enhancing the aeration effect.

[0036] In order to optimize the airflow path, a central hole 8 corresponding to the fan blade 7 is provided at the center of the upper wall of the dissolved oxygen box 1; a plurality of air holes 9 are evenly provided at the edge of the upper wall of the dissolved oxygen box 1. In this embodiment, the fan blade 7 blows air downward, continuously sending outside air into the grid frame 4, and the air diffuses and circulates in the grid frame 4 and rises. In the grid frame 4, the air fully contacts the dispersed sewage to dissolve oxygen, and finally is discharged from the air holes 9 on the outer ring side.

[0037] In order to ensure that there is enough aeration space on the upper part of the dissolved oxygen tank 1, the liquid level in the dissolved oxygen tank 1 needs to be lower than the grid 4. In this embodiment, the lower side of the dissolved oxygen tank 1 is connected to a downpipe 10, and the sewage after aeration and dissolved oxygen passes through the downpipe 10 and finally enters the four fine filter tanks 15 on the lower side of the dissolved oxygen tank 1, and is filtered into clean water by the filter layer in the fine filter tank 15 and then discharged. The interior of the fine filter tank 15 and its connection structure are prior art, which is not the focus of this embodiment and will not be described in detail in this embodiment.

[0038] A vertical lifting rod 11 and a bracket 12 for guiding the lifting and lowering of the lifting rod 11 are provided in the dissolved oxygen tank 1. Specifically, the bracket 12 is connected to the bottom of the dissolved oxygen tank 1. A through hole is provided on the bracket 12. The lifting rod 11 vertically corresponds to the sewer pipe 10. A plug 13 is connected to the lower end of the lifting rod 11. The plug 13 is a disc-shaped structure with a T-shaped cross section. When it descends, it can block the upper end of the sewer pipe 10, so that the sewage is no longer discharged through the sewer pipe 10. A floating ball 14 is connected to the upper end of the lifting rod 11. The floating ball 14 is located below the grid 4. The floating ball 14 rises and falls with the liquid level in the dissolved oxygen tank 1. When the liquid level rises, the floating ball 14 drives the lifting rod 11 and the plug 13 to rise. The plug 13 is separated from the sewer pipe 10 and no longer blocks the upper end of the sewer pipe 10. The sewage is discharged through the sewer pipe 10. When the liquid level drops, the plug 13 blocks the sewer pipe 10, so that the water level changes within a certain range. When the water level is the highest, the float 14 is lower than the grid 4, and the liquid level in the dissolved oxygen tank 1 is also lower than the grid 4, so that the sewage is prevented from immersing the grid 4, ensuring that there is enough aeration space in the dissolved oxygen tank 1, thereby ensuring that the sewage at the grid 4 is fully in contact with the air and the sewage at the grid 4 has a good dissolved oxygen effect.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
