[0002] A secondary water supply water tank is used to store domestic water transported by the tap water pipe network, and then it is pressurized and transported to users' homes to achieve secondary water supply for high-rise users.

[0003] After long-term use, impurities may be generated in the tap water pipe network and the secondary water supply water tank. If not processed in time, these impurities may be transported to users' homes along with domestic water, causing harm to users' health.

During the peak water consumption period, by spreading the adsorption particles inside the adsorption box, the flow velocity of the water flow in the water treatment pipe is increased to meet the water consumption needs of users during the peak water consumption period; in other periods, by using the expansion and contraction member to squeeze the adsorption particles to reduce the gap between the adsorption particles, thereby improving the water purification effect and further improving the quality of domestic water for users.

[0005] However, the above patent has the following problems: During the peak water consumption period, due to the spreading of adsorption particles, the gap between the adsorption particles increases, resulting in a decrease in the filtering effect of the adsorption particles on water, and further leading to a decrease in the quality of domestic water for users. Summary of the Invention

[0006] The purpose of the present invention is to provide a water purification treatment device for a secondary water supply water tank, aiming to solve the technical problem that the quality of domestic water for users decreases due to the reduction of the filtering effect during the peak water consumption period in the prior art.

[0009] Further technical solution: The first filtering component includes a filtering box arranged on the spare pipe. Both side surfaces of the filtering box are communicated with the spare pipe, and an activated carbon packet is installed inside the filtering box.

[0010] Further technical solution: The second filtering component includes a filtering cylinder installed inside the plugging inner pipe, and a plurality of activated carbon plates are installed inside the filtering cylinder.

[0011] Further technical solution: One end of the spare pipe is communicated with a water inlet branch pipe. One end of the water inlet branch pipe is communicated with the main pipe. A third valve is arranged on the water inlet branch pipe. The bottom of the main pipe is communicated with a sewage main pipe. The sewage main pipe is located on one side of the second filtering component away from the water outlet end of the spare pipe. A filtering plate is arranged at the bottom of the plugging inner pipe. Initially, the filtering plate is located above the sewage main pipe. A fifth valve is arranged on the sewage main pipe. A fourth valve is arranged on the main pipe. The fourth valve is located between the water inlet end of the spare pipe and the water inlet branch pipe.

[0012] Further technical solution: A plurality of the activated carbon plates are all slidably installed inside the filtering cylinder, and a second return spring is connected between the plurality of activated carbon plates. A tension spring is connected between the outermost activated carbon plate and the filtering cylinder.

[0013] Further technical solution: The activated carbon plate includes an outer ring. The outer ring is slidably installed inside the filtering cylinder. Filter meshes are arranged on both side surfaces of the outer ring. Activated carbon particles are filled between the two filter meshes.

[0014] Further technical solution: The filtering cylinder is slidably installed inside the plugging inner pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In the present invention, by providing a spare pipe and using the second filtering component to block the spare pipe initially, the usage frequency of the spare pipe can be greatly reduced. During the peak water consumption period, the water delivery power of the water pump increases, the water pressure in the main pipeline increases, and the water flow will push the blocking inner pipe to move through the second filtering component, thereby exposing the water inlet end of the spare pipe. Part of the water passes through the spare pipe, increasing the water flow rate while also avoiding the reduction of the filtering effect.

[0019] 3. In the present invention, by providing the first return spring, initially, the filter cylinder is located beside the filter plate, preventing water from passing over the second filtering component from the filter plate and reducing the water filtering effect. At the same time, during backwashing, the backflow water will push the filter cylinder to move above the filter plate. When the impurities on the surface of the activated carbon plate fall off, the impurities will directly pass through the filter cylinder and the filter plate and fall into the main sewage pipe, and then be discharged, improving the backwashing effect of the activated carbon plate.

[0020] 4. In the present invention, by providing the water inlet branch pipe and the sewage branch pipe, the second filtering component and the first filtering component can be backwashed while supplying water to users, without stopping water supply, which greatly facilitates the water use of residents.

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] The following describes the specific implementation of the present invention in detail in conjunction with specific embodiments.

[0029] As Figures 1 - 5 shown, a water purification treatment device for a secondary water supply water tank provided by the present invention includes a main pipeline 1, the main pipeline 1 is installed between the household water supply pipe and the water pump, an inverted "U"-shaped spare pipe 2 is installed on the main pipeline 1, a first filter assembly is arranged on the spare pipe 2, and a filter mechanism 7 is installed inside the main pipeline 1;

[0030] The filter mechanism 7 includes a sealing inner pipe 72 slidably installed inside the main pipeline 1, a second stop bar 75 is fixedly connected inside the main pipeline 1, one end of the sealing inner pipe 72 abuts against the second stop bar 75, and a compression spring 71 is connected between the other end of the sealing inner pipe 72 and the main pipeline 1. Initially, one end of the sealing inner pipe 72 blocks the water inlet end of the spare pipe 2, and a second filter assembly is installed inside the sealing inner pipe 72.

[0031] During the peak water consumption period, the water delivery power of the water pump increases, the water pressure inside the main pipeline 1 increases, and the water flow will push the sealing inner pipe 72 to move through the second filter assembly, thereby exposing the water inlet end of the spare pipe 2. Part of the water passes through the spare pipe 2, increasing the water flow rate and avoiding the reduction of the filtering effect at the same time;

[0032] During other water usage periods, the inner pipe 72 will block the water inlet end of the standby pipe 2, causing all water to pass through the main pipeline 1, reducing the use of the first filter component in the standby pipe 2, and lowering the replacement frequency of the first filter component. At the same time, when the second filter component is severely blocked, the standby pipe 2 can also be used as an emergency water pipe. At this time, the state of the first filter component becomes particularly important. That is, when the first filter component is slightly blocked, its water throughput is relatively large and can meet the user's needs. However, when the first filter component is also severely blocked, the water pressure at this time cannot meet the user's needs.

[0033] A water purification treatment device for a secondary water supply water tank provided by the present invention. In this embodiment, the first filter component includes a filter box 3 provided on the standby pipe 2. Both side surfaces of the filter box 3 communicate with the standby pipe 2, and an activated carbon packet 8 is installed inside the filter box 3.

[0034] Specifically, the filter box 3 includes a box body and a cover body, and the box body and the cover body are fixed by bolts, so that the activated carbon packet 8 can be replaced.

[0035] A water purification treatment device for a secondary water supply water tank provided by the present invention. In this embodiment, the second filter component includes a filter cylinder 710 installed inside the plugging inner pipe 72, and a plurality of activated carbon plates 79 are installed inside the filter cylinder 710.

[0036] The plurality of activated carbon plates 79 perform multiple filtrations on the water, improving the filtration and purification effect of the water.

[0037] A water purification treatment device for a secondary water supply water tank provided by the present invention. In order to backwash the second filter component, enable the second filter component to be used for a longer time, and reduce the replacement frequency of the second filter component. In this embodiment, one end of the standby pipe 2 is connected to an inlet branch pipe 6, one end of the inlet branch pipe 6 is connected to the main pipeline 1, a third valve 12 is provided on the inlet branch pipe 6, the bottom of the main pipeline 1 is connected to a sewage main pipe 4, the sewage main pipe 4 is located on the side of the second filter component away from the water outlet end of the standby pipe 2, a filter plate 73 is provided at the bottom of the plugging inner pipe 72. Initially, the filter plate 73 is located above the sewage main pipe 4, a fifth valve 14 is provided on the sewage main pipe 4, and a fourth valve 13 is provided on the main pipeline 1. The fourth valve 13 is located between the water inlet end of the standby pipe 2 and the inlet branch pipe 6.

[0038] Specifically, when backwashing the second filtering component, close the fourth valve 13, open the third valve 12 and the fifth valve 14, and introduce water into the main pipeline 1. The water enters the standby pipe 2 from the water inlet branch pipe 6, and then enters the main pipeline 1 from the water outlet end of the standby pipe 2. Due to the relatively high water pressure in the main pipeline 1, the water flow will be divided into two parts. One part continues to be transported to users along the main pipeline 1, and the other part will flow back. The backflow water passes through the second filtering component and is discharged from the sewage main pipe 4. During this process, the backflow water will carry away the impurities on the second filtering component, making the second filtering component as good as new.

[0039] This process can be automatically carried out during the low water consumption period, without stopping water supply, and the second filtering component can be backwashed, which is more convenient to use.

[0040] For a water purification treatment device for a secondary water supply water tank provided by the present invention, in order to improve the backwashing effect, in this embodiment, a plurality of the activated carbon plates 79 are all slidably installed inside the filter cylinder 710, and a second return spring 711 is connected between the plurality of the activated carbon plates 79, and a tension spring 78 is connected between the outermost activated carbon plate 79 and the filter cylinder 710.

[0041] Specifically, during backwashing, the water flow will impact a plurality of activated carbon plates 79. Since the water consumption of users is unstable (multiple users will not use water at the same time), the water pressure in the main pipeline 1 will be high and low, so the force of the water flow pushing the activated carbon plates 79 will constantly change. Under the action of the tension spring 78 and the second return spring 711, the plurality of activated carbon plates 79 will vibrate reciprocally, which accelerates the shedding of impurities on the activated carbon plates 79 and improves the backwashing effect on the activated carbon plates 79.

[0042] For a water purification treatment device for a secondary water supply water tank provided by the present invention, in this embodiment, the activated carbon plate 79 includes an outer ring 791, the outer ring 791 is slidably installed inside the filter cylinder 710, both side surfaces of the outer ring 791 are provided with filter meshes 793, activated carbon particles 794 are filled between the two filter meshes 793, a plurality of installation grooves 792 are formed on the side surface of the outer ring 791, and one end of the second return spring 711 is installed in the installation groove 792.

[0043] Specifically, during normal use, the water in the main pipeline 1 will push a plurality of activated carbon plates 79 to contact each other, so that the second return spring 711 is compressed. During backwashing, under the impact of the water flow and the pulling of the second return spring 711, the plurality of activated carbon plates 79 are separated, so that the impurities on the surfaces of each activated carbon plate 79 can fall off.

[0044] A water purification treatment device for a secondary water supply water tank provided by the present invention. When installing the second filtering component, the second filtering component cannot be directly installed above the filter plate 73. Otherwise, water will pass over the second filtering component from the filter plate 73, resulting in a reduction in the water filtering effect. When backwashing the activated carbon plate 79, impurities on the side of the middle activated carbon plate 79 will fall between multiple activated carbon plates 79. Since the impurities cannot be discharged, the impurities will gradually accumulate, affecting the water passing capacity of the activated carbon plate 79. Therefore, in this embodiment, the filter cylinder 710 is slidably installed inside the plugging inner tube 72. A first return spring 76 is connected between the filter cylinder 710 and the plugging inner tube 72. A third stop bar 77 and a first stop bar 74 for blocking the filter cylinder 710 are fixedly connected inside the plugging inner tube 72. Among them, the first stop bar 74 is located on the side of the filter plate 73 away from the filter cylinder 710, so that the filter cylinder 710 can only move between the third stop bar 77 and the first stop bar 74.

[0045] Specifically, during normal use, due to the blocking of the third stop bar 77, the filter cylinder 710 is fixed relative to the plugging inner tube 72. When the water pressure increases, the filter cylinder 710 will push the plugging inner tube 72 to move through the third stop bar 77. During backwashing, the water pressure of the backflow water will overcome the elastic force of the first return spring 76 and push the filter cylinder 710 to move through the activated carbon plate 79, so that the filter cylinder 710 abuts against the side of the first stop bar 74. At this time, the filter cylinder 710 is located above the filter plate 73. When the impurities on the surface of the activated carbon plate 79 fall off, the impurities will pass through the filter cylinder 710 and the filter plate 73 and fall into the sewage main pipe 4, and then be discharged, improving the backwashing effect of the activated carbon plate 79.

[0046] A water purification treatment device for a secondary water supply water tank provided by the present invention. In order to backwash the activated carbon packet 8, extend the service life of the activated carbon packet 8, and reduce the frequency of replacing the activated carbon packet 8, in this embodiment, the bottom of the standby pipe 2 is communicated with a sewage branch pipe 5. One end of the sewage branch pipe 5 is communicated with the sewage main pipe 4. A first valve 9 is arranged on the sewage branch pipe 5. A second valve 10 is arranged on the standby pipe 2. The second valve 10 is located between the sewage branch pipe 5 and the water inlet end of the standby pipe 2.

[0047] Specifically, when backwashing the activated carbon packet 8, close the second valve 10, the third valve 12, and the fifth valve 14, open the first valve 9 and the fourth valve 13, and introduce water into the main pipe 1. A part of the water will be supplied to users, and another part of the water will flow back from the water outlet end of the standby pipe 2. The backflow water will pass through the activated carbon packet 8 in the reverse direction. The impurities in the activated carbon packet 8 will flow into the sewage main pipe 4 together with the backflow water through the sewage branch pipe 5 and will finally be discharged.

[0048] Working principle:

[0049] During normal use, close the first valve 9, the fifth valve 14, and the third valve 12, open the fourth valve 13, and let water pass through the main pipeline 1. After being filtered by multiple activated carbon plates 79, it is finally delivered to the user's home. During the peak water usage period, due to the increased power of the water pump, its water production increases, causing the water pressure in the main pipeline 1 to increase. The greater water pressure will push the plugging inner pipe 72 through the activated carbon plates 79 and the filter cylinder 710, thereby opening the water inlet end of the standby pipe 2. Part of the water passes through the standby pipe 2, increasing the water flow while avoiding a reduction in the filtering effect.

[0050] When backwashing the activated carbon plates 79, close the fourth valve 13 and the first valve 9, open the second valve 10, the third valve 12, and the fifth valve 14. The water in the main pipeline 1 enters the standby pipe 2 from the inlet branch pipe 6, and then enters the main pipeline 1 from the water outlet end of the standby pipe 2. Due to the greater water pressure in the main pipeline 1, the water flow will be divided into two parts. One part continues to be delivered to the user along the main pipeline 1, and the other part will flow back. The backflowing water passes through the activated carbon plates 79 and is discharged from the sewage main pipe 4. During this process, the backflowing water will carry away the impurities on the activated carbon plates 79, making the activated carbon plates 79 as good as new.

[0051] When backwashing the activated carbon packet 8, close the second valve 10, the third valve 12, and the fifth valve 14, open the first valve 9 and the fourth valve 13. Part of the water in the main pipeline 1 will be supplied to the user, and the other part of the water will flow back from the water outlet end of the standby pipe 2. The backflowing water will pass through the activated carbon packet 8 in the reverse direction, and the impurities in the activated carbon packet 8 will flow into the sewage main pipe 4 along with the backflowing water through the sewage branch pipe 5 and will eventually be discharged. This process also does not require shutting off the water supply and only needs to be backwashed during the low water usage period.

[0052] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.

[0053] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
