Description

Technical Field

[0001] The utility model relates to the technical field of water treatment devices, in particular to a water quality regulating device. Background Art

[0002] The water quality in the river is very important for the lives of nearby villagers and the irrigation of farmland. If the river water is seriously polluted, a large number of bacteria and other microorganisms will have a serious impact on the lives of the villagers and will also have a serious impact on crops. Therefore, it is particularly important to regulate the water quality of the river water. Generally, water quality regulation is divided into the steps of impurity filtration, sedimentation, bacteria and microorganisms, heavy metal filtration, and then the regulated water is discharged. However, although today's water quality regulation devices can filter impurities and heavy metal bacteria, etc., they are inconvenient to maintain. The inside of the tank needs to be cleaned to prevent impurities from clogging, and it is too troublesome to clean them one by one.

[0003] Secondly, current water quality regulating devices will install filter screens when pipes are laid in river channels to filter out larger impurities, but particles and impurities mixed with dust cannot be completely filtered (because the water pump needs to be considered. If the filtration density is high, the water pumping of the water pump will be greatly hindered, which can easily cause the water pump to be damaged due to excessive load). The filter column in the sedimentation tank is easily clogged due to particle accumulation, which is not conducive to the overall purpose of the device to regulate the water. Cleaning is more troublesome because the tank is closed. When cleaning, the upper end cover of the tank needs to be opened, and then water is sprayed into the tank for flushing. Since there is a more unpleasant odor in a closed environment and it is also accompanied by certain risks, the overall process is more troublesome. In addition, there are multiple filter sedimentation tanks, which greatly prolongs the cleaning time.

[0004] Therefore, in view of the above, in order to achieve self-flushing and cleaning, there is no need for manual cleaning of impurities in the tank. A water quality regulating device is hereby proposed to solve such technical problems. Utility Model Content

During flushing, since the outer end of the filter hole is narrow and the inner end is wide, on the one hand, impurities are prevented from entering the filter column, and on the other hand, the pressure of the water ejected from the filter hole can be increased during flushing, so that the impurities blocked in the filter hole are processed. Secondly, after passing through the filter column and the filter funnel, the water gathers at the bottom of the filter sedimentation tank. Then the water pump is started to pump out the mixture of water and impurities inside the filter sedimentation tank through the drain pipe, thereby achieving the purpose of self-cleaning without manual cleaning.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example

[0030] See also Figure 1-10The utility model provides the following technical solutions: a water quality regulating device, comprising a filtering structure 1, an RO reverse osmosis filtering device 2, and a water storage structure, the filtering structure 1 comprising a filtering sedimentation tank 101, a filtering structure being installed in the filtering sedimentation tank 101, a water storage structure being connected to a flushing structure, and a flushing structure being connected to the filtering structure, a first water inlet 110 being connected to the bottom of the filtering sedimentation tank 101, a mounting pipe 12 being connected at the port of the first water inlet 110, a drain pipe 8 being connected to the surface of the mounting pipe 12, a fourth solenoid valve 10 being installed on the surface of the water outlet end of the drain pipe 8, a flushing structure comprising a third connecting pipe 18 connected to the water storage structure, a water pump 19 being connected to the water outlet end of the water pump 19, a flushing pipe 6 being connected to the water outlet end of the flushing pipe 6, a second solenoid valve 7 being provided on the surface of the flushing pipe 6, a first connecting pipe 3 being connected to the port of the flushing pipe 6, and the first connecting pipe 3 being connected to the filtering structure. Its filtering structure includes a first water outlet pipe 105 inserted from the surface of the filtering sedimentation tank 101 into the filtering sedimentation tank 101, and the end of the first water outlet pipe 105 is connected to a first three-way pipe 106, and a filtering funnel 104 is installed at the end of the first water outlet pipe 105, and the inner wall of the filtering funnel 104 is stepped with an annular retaining ring 112. Its filtering structure also includes a second water outlet pipe 107 inserted from the surface of the filtering sedimentation tank 101 into the filtering sedimentation tank 101, and the end of the second water outlet pipe 107 is connected to a second three-way pipe 109, and the outer surface of the second water outlet pipe 107 is symmetrically distributed with filtering columns 108, and the first connecting pipe 3 is connected to one of the ports of the first three-way pipe 106 and the second three-way pipe 109.

[0031] In this embodiment, the specific working principle is as follows: First, it is explained that the water pump connected to the installation pipe 12 is not drawn in the attached figure. The water pump has the same structure as the water pump 19. The device is laid in the river channel through a pipeline and a filter screen is set on the pipeline in the river channel. Then the water in the river channel is pumped into the filter sedimentation tank 101 through the installation pipe 12 through the water pump. During this period, the fourth solenoid valve 10 and the second solenoid valve 7 are in the closed state, and the other solenoid valves are in the open state. The river water is injected into the filter sedimentation tank 101. Through the injection of water, the water level in the filter sedimentation tank 101 rises rapidly. At this time, the water passes through the filter column 108 to filter the impurities in the water, and then the water will continue to spread upward through the filter funnel 104, and is initially filtered by the filter plate 103. Then the water overflows the filter plate 103 and enters the filter funnel 104 and contacts the annular retaining ring 112 to filter the water. Filtered, then enters the RO reverse osmosis filter device 2 to filter heavy metals, bacteria and other microorganisms in the water, and then enters the water storage structure through the second connecting pipe 15. When it is necessary to clean the sediment in the filter sedimentation tank 101 and the impurities blocked on the surface of the filter column 108, start the water pump 19. At this time, the water in the water storage structure is pumped into the flushing pipe 6. At this time, except for the fourth solenoid valve 10 and the second solenoid valve 7 which are in the open state, the other solenoid valves are in the closed state. The water generates a strong pressure through the water pump 19, and then backwashes the filter column 108 and the filter funnel 104, thereby removing the impurities blocked on the two, making them fall to the bottom of the filter sedimentation tank 101, and then discharged through the drain pipe 8, thereby achieving the purpose of self-cleaning without manual cleaning, and solving the problem that the existing water quality adjustment device cannot achieve self-cleaning of impurities in the filter sedimentation tank.

[0032] According to the above, in order to effectively filter the river water entering the filter sedimentation tank 101, please refer to Figure 7 It can be seen that the surface of the annular retaining ring 112 is provided with openings 113 in a circular array, and the inclination of the openings 113 is consistent with the inclination of the annular retaining ring 112 , and effective impurity interception is achieved through the preliminary filtration of the filter plate 103 and the filtration of the annular retaining ring 112 .

[0033] In order to prevent excessive impurities in the water from entering the filter column 108 and to effectively flush the filter column 108, please refer to Figure 8 and Figure 9 It can be seen that a filter hole 114 is opened on the surface of the filter column 108, and the filter hole 114 has a narrow outer opening and a wide inner opening. Through the above arrangement, the impurities can be effectively blocked on the outer surface of the filter column 108. When flushing, due to the effect of water pressure, it generates a strong jet force, thereby effectively cleaning the impurities blocking the surface of the filter column 108.

[0034] In order to prevent the river water entering the filtering and settling tank 101 through the first water inlet 110 from being directly sprayed upward, Figure 5 and Figure 10 It can be seen that a block 111 is installed on the bottom surface of the filter sedimentation tank 101, and the lower end of the block 111 corresponds to the first water inlet 110, so that water can be sprayed in all directions when entering the filter sedimentation tank 101, which can effectively achieve the sedimentation effect.

[0035] See Figure 5 It can be seen that a filter plate 103 is installed at the upper end of the filter funnel 104 , and a mounting rod 102 is provided on the upper end surface of the filter plate 103 . The mounting rod 102 is connected to the inner wall of the upper end of the filter sedimentation tank 101 .

[0036] See Figure 1 and Figure 2 It can be seen that the other port of the first tee pipe 106 and the second tee pipe 109 is connected to the second connecting pipe 4, and the second connecting pipe 4 is connected to the RO reverse osmosis filter device 2 through the first connecting pipe 14. The RO reverse osmosis filter device 2 includes a second water inlet 201 and a water outlet 202, and its first connecting pipe 14 is connected to the second water inlet 201.

[0037] See Figure 1 It can be seen that the water storage structure includes a water tank 16, and a third three-way pipe 17 is installed on the front end face of the water tank 16. One end of the third three-way pipe 17 is connected to the third connecting pipe 18, and the other end is connected to the water pump. The rear end face of the water tank 16 is connected to the second connecting pipe 15, and the second connecting pipe 15 is connected to the water outlet 202.

[0038] See Figure 2 It can be seen that the first solenoid valve 5 is provided at the connection between the surface of the second connecting pipe 4 and the first three-way pipe 106 and the second three-way pipe 109, and the third solenoid valve 9, the fifth solenoid valve 11 and the sixth solenoid valve 13 are respectively installed on the surface of the mounting pipe 12.

[0039] Among them, the port of the installation pipe 12 is connected to a water pump, and the water outlet end of the drainage pipe 8 is connected to the collection tank through a pipe.
