DETAILED DESCRIPTION

[0036] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] like Figure 1-4 As shown, a water purification device of the utility model comprises a water inlet pipe 1, a filter 2, an air inlet pipe 3, a mixing pipe 4, a three-way pipe fitting 5, a foam collecting bucket 6 and a mud collecting bucket 7.

[0038] The water inlet pipe 1 is used to connect to the polluted water body, and can cooperate with a water pump to extract the polluted water body, or the weight of the water body can be used to allow the polluted water body to flow naturally into the water inlet pipe 1.

[0039] The filter 2 is used to filter polluted water, and is usually composed of a filter box and filter material located inside the filter box. After the polluted water flows through the filter material, impurities in the polluted water are blocked to complete the purification of the water.

[0040] The air inlet pipe 3 is used to add air into the water in the water purification device, thereby increasing the oxygen content in the purified water.

[0041] The mixing tube 4 is used to improve the mixing stability and uniformity of water and air. The mixing tube 4 includes a plurality of pipe sections 41, and each pipe section 41 includes a plurality of diversion pipes 411, wherein the plurality of diversion pipes 411 in the same pipe section 41 are connected in parallel, and the plurality of diversion pipes 411 in two adjacent pipe sections 41 are connected in series. The repeated division and mixing of water and air bubbles by the plurality of diversion pipes 411 can make the air be refined into tiny bubbles and fully mixed in the water, so that the gas-liquid phase in the water purification device is in a stable state, which can reduce the vibration and water hammer damage caused by the unstable gas-liquid phase, improve the oxygenation amount of the purification device, and allow part of the ammonia nitrogen dissolved in the water to enter the bubbles due to the gas flow, thereby reducing the ammonia nitrogen content of the sewage to a certain extent.

[0042] The three-way pipe fitting 5 is used to connect other components. The three-way pipe fitting 5 includes three interconnected joints, one joint is connected in series with the filter 2 and the water inlet pipe 1 in sequence, and the other two joints are connected to the air inlet pipe 3 and the mixing tube 4 respectively. The joint connecting the three-way pipe fitting 5 and the mixing tube 4 is connected to a plurality of branch pipes 411 located at one end of the mixing tube 4, so that after the polluted water enters the water inlet pipe 1, it flows through the filter 2, the three-way pipe fitting 5 and the mixing tube 4 in sequence, and is discharged to the pure water storage or the polluted water through the mixing tube 4. In this process, air can enter the water in the pipeline through the air inlet pipe 3, and the mixing tube 4 can fully mix the air and water to form a stable gas-liquid phase to ensure the normal operation of the water purification device.

[0043] like Figure 2 As shown, in order to avoid an excessive number of shunt pipes 411 which would increase the space occupied by the mixing tube 4 and to avoid the shunt pipes 411 being too thin in inner diameter and easily blocked, it is preferred to have two shunt pipes 411 in each pipe section 41 .

[0044] After the mixed liquid of air and water enters the pipe section 41 from the inlet, the gas-liquid phase (i.e., the mixed liquid of air and water) will enter the two branch pipes 411 respectively. Due to the air resistance phenomenon of the gas in the branch pipe 411, the two branch pipes 411 in the same pipe section 41 form pressures P1 and P2 respectively. When there are more bubbles entering the first branch pipe 411, the air resistance is strong and the pressure P1 rises. P1>P2. At this time, the pressure of the first branch pipe 411 at the inlet of the pipe section 41 is high and the resistance is large. The gas phase entering the first branch pipe 411 is reduced, P1 decreases, and the gas phase is forced to enter the second branch pipe 411; entering the second branch pipe The gas phase in the flow pipe 411 becomes more, the gas resistance is strong and the pressure P2 rises; when P2>P1, the pressure of the second branch pipe 411 at the entrance of the pipe section 41 is high and the resistance is large, the gas phase entering the second branch pipe 411 is reduced, and the gas phase is forced to enter the first branch pipe 411; the two branch pipes 411 in the same pipe section 41 push and pull each other to form a cycle, so that the gas phase is pulled left and right at the entrance of the pipe section 41 and broken, and a relatively uniform and stable gas-liquid mixed phase is formed at the outlet. Through the series effect of the multi-stage pipe section 41, the gas-liquid phase repeatedly acts in the combined structure of the multi-stage pipe section 41, and finally forms an extremely stable gas-liquid mixed phase.

[0045] In order to ensure the stability of the operation of the gas-liquid phases in the two branch pipes 411 in the same pipe section 41, it is preferred that the two branch pipes 411 in the same pipe section 41 are symmetrically arranged about the center line of the mixing tube 4; specifically, it is preferred that the pipe section 41 is diamond-shaped with rounded top angles to avoid greater resistance to the gas-liquid phases due to the existence of too many complex structures.

[0046] like Figure 1As shown, the water inlet pipe 1 is arranged in the horizontal direction; the air inlet pipe 3 is arranged in the vertical direction and is located above the water inlet pipe 1; the mixing tube 4 is arranged in the vertical direction and is located below the water inlet pipe 1. After the polluted water naturally flows into the water inlet pipe 1, it is first filtered by the filter 2, and then naturally flows into the mixing tube 4. At the same time, the external air is affected by the air pressure and is sucked into the air inlet pipe 3, thereby achieving mixing of air and water.

[0047] The foam collecting hopper 6 is used to remove floating foam in the water body. The foam collecting hopper 6 includes a foam collecting bin 61, a first water inlet pipe 62, a first water outlet pipe 63 and a defoaming pipe 64, wherein the first water inlet pipe 62 and the first water outlet pipe 63 are respectively fixedly arranged at the lower part of the peripheral side of the foam collecting bin 61 and are connected with the interior thereof, and the end of the first water inlet pipe 62 away from the foam collecting bin 61 is connected with a plurality of branch pipes 411 located at the end of the mixing tube 4 away from the three-way pipe fitting 5, so that the mixed liquid in the mixing tube 4 flows into the foam collecting bin 61; the defoaming pipe 64 is fixedly arranged on the top side of the foam collecting bin 61 and is connected with the interior thereof, so that the floating foam at the liquid surface in the foam collecting bin 61 can be extracted and discharged by using the defoaming pipe 64.

[0048] like Figure 3 As shown, the first water inlet pipe 62 and the first water outlet pipe 63 are relatively arranged on both sides of the foam collecting bin 61; the bottom side of the foam collecting bin 61 is horizontal, and the height of the foam collecting bin 61 gradually decreases along the direction from the defoaming pipe 64 to the first water inlet pipe 62 or along the direction from the defoaming pipe 64 to the first water outlet pipe 63, that is, the top of the foam collecting bin 61 is conical, which can concentrate the floating foam, thereby facilitating the use of the defoaming pipe 64 to centrally extract the floating foam.

[0049] One end of the air inlet pipe 3 away from the three-way pipe 5 is connected to the outside world. Impurities will enter the water in the device through the air inlet pipe 3. The weakening of the filtering performance of the filter 2 will also allow impurities to enter the subsequent water body, so that the filtered water body still has floating foam and impurities. The mud collecting bucket 7 is used to collect and discharge the impurities in the filtered water body. Figure 4 As shown, the mud collecting bucket 7 includes a mud collecting bin 71, a second water inlet pipe 72, a second water outlet pipe 73 and a mud discharge pipe 74, wherein the second water inlet pipe 72 is fixedly arranged on the peripheral side of the mud collecting bin 71 and is communicated with the interior thereof, and the second water inlet pipe 72 is communicated with the first water outlet pipe 63, so that the water body after foam removal in the foam collecting bin 61 enters the mud collecting bin 71; large-sized impurities in the water body sink and accumulate at the bottom of the mud collecting bin 71 due to gravity, the second water outlet pipe 73 is fixedly arranged on the top side of the mud collecting bin 71 and is communicated with the interior thereof; the mud discharge pipe 74 is fixedly arranged on the bottom side of the mud collecting bin 71 and is communicated with the interior thereof, so as to separate and discharge the water body and the sludge respectively.

[0050] The top side of the mud collecting bin 71 is horizontal, and the height of the mud collecting bin 71 gradually decreases along the direction from the mud discharge pipe 74 to the second water inlet pipe 72, that is, the bottom of the mud collecting bin 71 is conical, which is convenient for concentrating the sludge, thereby facilitating the centralized discharge of the sludge using the mud discharge pipe 74.

[0051] The control valve 8 is used to control the on-off of the pipeline and the flow rate of the water in the pipeline. The control valve 8 is fixedly connected to the water inlet pipe 1, the air inlet pipe 3 and the mud discharge pipe 74, and is connected to them to control whether water enters the water inlet pipe 1, whether outside air can enter the air inlet pipe 3, and whether the sludge in the mud collecting bucket 7 is discharged.

[0052] The working principle of a water purification device of the utility model is as follows:

[0053] like Figure 1 As shown, open the control valve 8 on the water inlet pipe 1 and the air inlet pipe 3, close the control valve 8 on the mud collecting bucket 7, and after the water inlet pipe 1 is connected with the polluted water body, the polluted water body first flows into the filter 2 through the water inlet pipe 1 for filtering and impurity removal, and then flows into the mixing tube 4 through the three-way pipe fitting 5. At the same time, affected by the pressure change, the outside air will be sucked into the air inlet pipe 3 (the air can also be introduced into the air inlet pipe 3 by an air pump extraction method), and the air and the water body are repeatedly cut and mixed through the mixing tube 4 to form a uniform gas-liquid phase, and then flow into the foam collecting bucket 6 and the mud collecting bucket 7 in turn, and finally are extracted to the corresponding pure water body storage position through the second water outlet pipe 73; during this period, the floating foam at the liquid surface of the water body can be extracted by the defoaming pipe 64, and the water body can also be defoamed and desilted by opening the control valve 8 on the mud discharge pipe 74, thereby improving the purification efficiency of the water body.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
