Abstract
Description
Technical Field
[0001] This utility model relates to the field of water purification technology, and in particular to a device for treating the turbidity of water. Background Technology
[0002] In water purification, turbidity removal is a crucial step in ensuring water quality safety. Turbidity refers to the degree to which a solution impedes the passage of light, encompassing both the scattering of light by suspended solids and the absorption of light by solute molecules. For purified water awaiting discharge, the remaining suspended solids are often encased in air bubbles. These air bubbles, formed and gradually accumulating during the purification process, obstruct light transmission during turbidity testing. This scattering and reflection of light directly affects the turbidity measurement results, thus impacting the water quality's final grade. Utility Model Content
[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a turbidity treatment device for water that helps to release air bubbles from purified water.
[0004] To solve the above-mentioned technical problems, the present invention provides a water turbidity treatment device, comprising a first water tank and a second water tank connected to each other for eliminating air bubbles in the water. An inlet pipe is connected to one side of the first water tank, and a sampling pool is connected to one side of the outlet end of the second water tank, while a collection pool is connected to the other side. A third switch valve is provided at the connection point between the collection pool and the second water tank. The sampling pool is also connected to the inlet end of the second water tank on one side. A flushing mechanism connected to the first water tank is also provided at the connection point between the sampling pool and the second water tank.
[0005] Using the above structure, the purified water flows through the first and second water tanks. The two tanks increase the flow distance of the purified water, releasing air bubbles during this increased flow distance to remove residual suspended solids and ensure the turbidity test pass rate of the purified water. To ensure the factory pass rate of the purified water, a sampling pool is connected in the outlet direction. If the sample fails, the water can be returned to the second water tank, effectively increasing the travel distance of the purified water and continuing to release air bubbles during the flow until the sample passes. Then, the third valve is opened, and the purified water flows into the collection tank and is discharged for use. When it is necessary to clean the inside of the water tanks, the flushing mechanism is activated, and the water in the sampling pool is pumped into the two water tanks as cleaning water. Since the cleaning water has been purified, there are only tiny suspended impurities in the tanks, and these impurities can flow with the water flow, making it difficult for them to adhere to the tank walls. Therefore, the injected cleaning water can be discharged directly. The structure is simple and compact, and easy to use.
[0006] To facilitate the release of air bubbles in the water and simplify the structure, preferably, a first baffle and a second baffle are provided at intervals inside the first water tank. The first baffle and the second baffle are staggered in the vertical direction, and the inner side wall of the first water tank, the first baffle and the second baffle together form an "S" shaped flow channel structure.

[0008] To facilitate the phased collection and circulating treatment of water at the first flow tank, preferably, a first switching valve is connected to the first return pipe, and a second switching valve is connected to the second return pipe.
[0009] To further increase the flow distance and facilitate the release of air bubbles in the water, preferably, a connecting pipe is provided between the first and second water tanks, and a third baffle is provided in the upper part of the second water tank. The third baffle divides the inner cavity of the second water tank into a first chamber and a second chamber connected at the lower end. The first chamber is connected to the connecting pipe, and the second chamber is connected to the water outlet pipe fixed on the second water tank.
[0010] To facilitate the discharge of gas released after the bubbles burst in the water in the two water tanks, while ensuring water output efficiency, it is preferable that the upper part of the third baffle is provided with a through hole that connects the first chamber and the second chamber.
[0011] To facilitate sampling and drainage, and to ensure timely discharge of qualified water, a three-way valve is preferably connected to the outlet end of the outlet pipe. A sampling pipe is connected to one side of the three-way valve, and a drain pipe connected to the collection tank is connected to the other side. A fourth switch valve is provided at the outlet end of the sampling pipe and is connected to the sampling pool. A return pipe is connected to one side of the sampling pool, and a connecting pipe is provided at the outlet end of the return pipe. A first water pump is also connected to the return pipe, and a third switch valve is connected to the drain pipe.
[0012] To make full use of the water source in the sampling pool and to facilitate rapid rinsing of the flow channels in the first water tank, preferably, the rinsing mechanism includes a rinsing pipe connected to the return pipe, a branch pipe connected to the outlet end of the rinsing pipe, and three nozzles extending into the first water tank connected to the branch pipe. Each vertical flow channel of the "S"-shaped flow channel structure is directly opposite a nozzle. A second water pump is also connected to the rinsing pipe.
[0013] To facilitate the rapid discharge of cleaning water and to circulate and purify the cleaning water to save costs, preferably, a drain pipe is provided at the lower end of both the first and second water tanks, and the outlet of the drain pipe is connected to the filter tank.
[0014] Beneficial effects: This utility model sets up two water tanks to increase the water flow distance, so as to fully release the air bubbles in the water, reduce the residue of suspended solids in the water and ensure the turbidity qualification rate; in this process, a sampling pool is set up to facilitate sampling at any time and circulation, and thereby further increase the flow distance to release air bubbles in the water; the flushing mechanism is set up to pump the water in the sampling pool back for reuse, saving costs.

The outlet end of the return pipe 20 is connected to the connecting pipe 101. A first water pump 21 is also connected to the return pipe 20, and a third switch valve 141 is connected to the drain pipe 14.
[0027] The flushing mechanism includes a flushing pipe 201 connected to the return pipe 20, a branch pipe 30 connected to the outlet end of the flushing pipe 201, and three nozzles 31 extending into the first water tank 11 connected to the branch pipe 30. Each vertical channel of the "S"-shaped flow channel structure is directly opposite a nozzle 31. A second water pump 22 is also connected to the flushing pipe 201.
[0028] Both the first water tank 11 and the second water tank 12 are provided with a drain pipe 15 at their lower ends, and the outlet end of the drain pipe 15 is connected to the filter tank 5.
[0029] The working principle of this utility model is as follows:
[0030] like Figure 1As shown, the purified water (hereinafter referred to as water) undergoes a final turbidity test before being supplied for use. The water then flows into the first flow tank 11 through the inlet pipe 10. Inside the first flow tank 11, the first baffle 41 and the second baffle 42 are staggered, creating an "S"-shaped flow channel structure. When the water flows through this channel, at the two turning points, in addition to the impact of the drop facilitating the release of air bubbles, the impact of the water flow against the inner wall of the first flow tank 11 during turning and the turbulence during the rise of the water surface also helps release air bubbles. Simultaneously, a first return pipe 111 is connected to the upper part of the first flow tank 11, and the outlet of the first return pipe 111 is connected to a return pool 112. During the initial water intake process, the second switch valve is closed. 115. Open the first switch valve 114 to discharge the suspended matter floating on the water surface in the first flow tank 11. This part of the suspended matter flows back into the return pool 112 with the subsequent water flow. When the return pool 112 accumulates a certain amount of water, the suspended matter in the water in the return pool 112 is all on the water surface. Open the second switch valve 115 to let the water in the return pool 112 flow back to the inlet pipe 10 and re-enter the first flow tank 11. When the water level in the return pool 112 drops to a certain height, close the second switch valve 115, that is, maintain the water level with the suspended matter floating in the return pool 112. After the water level rises to a certain height, open the second switch valve 115 again. This cycle is repeated to retain as much suspended matter as possible in the return pool 112, and at the same time, it can reduce the chance of air bubbles being trapped in the water, which helps to release air bubbles during the flow.
[0031] Water flowing from the first water tank 11 flows into the second water tank 12 through the connecting pipe 101. Once inside the second water tank 12, the water is first impacted by the drop to release air bubbles. The gas released from the bubbles is discharged through the outlet pipe 123, maintaining the air pressure balance inside the second water tank 12. As the water level rises, the water surface reaches the position of the through hole 431. The position of the outlet pipe 123 is set at the same height as the position of the through hole 431. At this time, the water and the gas released from the bubbles are discharged together through the outlet pipe 123.
[0032] Water discharged from the second flow tank 12 first flows to the three-way valve 102. At this time, the fourth switch valve 131 is opened, while the third switch valve 141 remains closed. The water flows into the sampling pool 2 through the three-way valve 102 and the sampling pipe 13. The staff takes samples in the sampling pool 2 to test the turbidity. During this process, the first water pump 21 is also turned on while the second water pump 22 is kept closed. This draws the water in the sampling pool 2 into the return pipe 20 and back into the connecting pipe 101. The water flowing out of the first flow tank 11 flows back into the second flow tank 12, which actually increases the water's travel distance. During the flow and pumping process of the first water pump 21, air bubbles in the water are released. Throughout the process, the water is in a circulating flow. Air bubbles in the water are continuously eliminated through turning flow and drop impact. Turbidity is tested at regular intervals.
[0033] Once the turbidity test is passed, the first water pump 21 and the fourth switch valve 131 are shut off, and the third switch valve 141 is opened. The water flows out through the drain pipe 14 to the collection tank 3 for later use.
[0034] During the intermittent water supply period of a batch of water, when it is necessary to clean the two water tanks, first open the drain pipe 15 connecting the lower ends of the first water tank 11 and the second water tank 12 to discharge the water remaining in the two water tanks and return it to the filter tank 5 through the drain pipe 15. Then, open the first switch valve 114 and the second switch valve 115. After this part of the water is discharged, turn on the first water pump 21 and the second water pump 22, and close the drain pipe 15 at the lower end of the second water tank 12. Pump the water in the sampling tank 2 as cleaning water into the flushing pipe 201, and then distribute it through the branch pipe 30 to the three nozzles 31 and spray it into the first water tank 11. The three channels in the "S"-shaped flow channel structure are flushed simultaneously. The flushing water slowly accumulates and the water level rises. On the one hand, the suspended solids in the return pool 112 are discharged into the first flow tank 11 through the first return pipe 111, the return pool 112 and the second return pipe 113. On the other hand, the water flows into the second flow tank 12 through the connecting pipe 101 to achieve flushing. The flushing water is continuously discharged through the drain pipe 15 under the first flow tank 11. At the same time, when the cleaning water in the second flow tank 12 begins to overflow into the sampling pool 2, the drain pipe 15 at the bottom of the second flow tank 12 is opened to discharge the cleaning water. The discharged cleaning water is also diverted back to the filter pool 5 for further circulation and purification.
[0035] It should be noted that, in order to ensure the smooth flow of water in the return pool 112 and reduce labor intensity, a water level gauge (not marked) should be installed in the return pool 112, and the water level gauge should be connected to the PLC controller (not marked). Therefore, the first switch valve 114 and the second switch valve 115 should also be electrically connected to the PLC controller to achieve automatic control. In addition, the staff should also take into account the accumulation thickness of suspended solids in the return pool 112 over time, in conjunction with the purification process, so as to adjust the water level to be retained after water discharge, so as to prevent suspended solids from returning to the first water tank 11 through the second return pipe 113.
[0036] In addition, the water remaining in sampling pool 2 is not suitable for discharge along with the water that has passed the turbidity test, as the bottom layer is a mixture of water before and after the turbidity test. It is more suitable to use it as cleaning water and then further purify it in order to control production costs. The water in the inlet of the first flow tank 11 is also not suitable for discharge and is more suitable for return and further purification.
[0037] In addition, during the rinsing process, the first water pump 21 and the second water pump 22 are turned on simultaneously. In addition to providing power for the water to be injected into the flushing pipe 201, some water will also flow into the second water tank 12 through the connecting pipe 101. However, this does not affect the cleaning effect. On the contrary, it can achieve the purpose of filling the two water tanks with water at the same time. Since the first water tank 11 is the first place where the water enters during the test, it contains more suspended solids than the second water tank 12. Therefore, the nozzle 31 is only set in the first water tank 11. During the cleaning, the second water tank 12 only needs to be rinsed by increasing the water flow rate. In particular, the volume of the sampling pool 2 should be greater than the sum of the volumes of the two water tanks in order to provide sufficient cleaning water. This cleaning water will then be diverted to the filter pool 5 for further purification. In fact, there is no waste of water resources. Not only will there be no stagnant water left in the pools during the water supply interval, but the cost of cleaning water will also be saved.
[0038] In addition, sampling pool 2 and reflux pool 112 should be cleaned regularly to avoid significant errors in turbidity detection results in the later stages of use. In this embodiment, the process of use involves flowing water, which not only helps to eliminate air bubbles in the water to ensure the efficiency of turbidity detection, but also ensures the quality of the water leaving the factory.
