Description

Technical Field

[0001] This invention relates to the field of water pollution control and treatment technology, and in particular to a secondary water supply treatment device. Background Technology

[0002] Secondary water supply is a water supply method used in urban high-rise residential buildings and communities where the municipal water supply network pressure is insufficient to supply water directly. Instead, municipal water is stored and pressurized through domestic water tanks, pumps, and pressurization equipment before being delivered to high-rise residents. It is an essential water supply method for high-rise buildings. As an important component of the secondary water supply process, domestic water tanks need to be cleaned and disinfected regularly to ensure water quality safety and avoid secondary pollution.

[0003] Disinfection of domestic water tanks requires soaking in disinfectant. However, due to the large volume of the tank and the need to fill it with disinfectant during soaking, a large amount of disinfectant is required, resulting in high processing costs. In addition, the input and output of disinfectant also consume a lot of time, leading to a decrease in processing efficiency.

[0004] In addition, to avoid corrosion of stainless steel or glass tube water tanks by high concentrations of disinfectant concentrate, disinfectants cannot be directly mixed inside the tank. They are usually prepared manually using a special plastic mixing container. However, due to the limited capacity of the mixing container, the process needs to be repeated multiple times to obtain a sufficient amount of disinfectant, which is cumbersome and significantly affects the processing efficiency.

[0005] Therefore, it is necessary to invent a secondary water treatment device to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a secondary water treatment device that effectively reduces the amount of disinfectant used while ensuring disinfection and sterilization effects, lowers treatment costs, and reduces the time required for input and output of disinfectant, thereby improving treatment efficiency. Furthermore, it allows for convenient direct preparation of disinfectant inside the water tank without corroding the tank, eliminating the need for a separate plastic mixing container for manual preparation of disinfectant. It also allows for larger single-use preparations, reducing the need for multiple preparations and further improving treatment efficiency. This addresses the problems mentioned in the background art, where the large water tank volume and the need to fill the tank with disinfectant during immersion disinfection result in high costs and time-consuming input and output of disinfectant, leading to reduced treatment efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a secondary water supply treatment device, comprising a secondary water supply storage unit, wherein a liquid preparation and filling unit is provided at the top of the inner cavity of the secondary water supply storage unit and a liquid supply unit is provided on the right side of the secondary water supply storage unit, wherein a driving unit for driving the liquid preparation and filling unit to unfold is also provided inside the secondary water supply storage unit, and the liquid preparation and filling unit is provided with two sets of mixing units with opposite stirring directions and a spraying unit for spraying bactericide; The liquid filling unit includes a top plate, with a liquid inlet hole at the top of the top plate and a flexible corrugated tube in a folded state fixedly connected to the bottom of the top plate.

[0010] Preferably, mounting grooves are provided on both sides of the bottom of the base plate, and a counterweight bottom cover is fixedly connected to the bottom of the base plate.

[0011] Preferably, the top and bottom outer sides of the raw material container are fixedly fitted with a fixing frame, and both fixing frames are fixedly installed on the right side of the water tank.

[0012] Preferably, the drive unit includes a guide shaft fixedly disposed vertically on the right side of the water tank cavity and a lead screw rotatably nested on the left side of the water tank cavity via a ball bearing. The top of the lead screw is connected to a motor fixedly disposed on the top of the water tank. A lifting frame is slidably sleeved on the outside of the guide shaft in the vertical direction via a linear bearing. The lifting frame is sleeved on the outside of the lead screw and is connected to the lead screw in a transmission manner.

[0013] Preferably, threaded sleeves are rotatably nested on both sides of the top of the lifting frame via ball bearings. Limiting pins are slidably inserted through the top front and rear sides of the lifting frame in the vertical direction. The bottom ends of the two limiting pins are fixedly connected to the top of the base plate. A return spring located between the base plate and the lifting frame is sleeved on the outside of any one of the limiting pins.

[0014] Preferably, any set of the mixing units includes a threaded rod and a rotating shaft that are rotatably nested on the top of the base plate via ball bearings in the vertical direction. The threaded rod is driven to the inside of an adjacent threaded sleeve. A rotating disk is fixedly connected to the top of the rotating shaft, and a stirring plate is fixedly installed on the top of the rotating disk.

[0015] Preferably, a drive wheel is fixedly sleeved on the bottom outer side of the threaded rod, and a driven wheel is fixedly sleeved on the bottom outer side of the rotating shaft.

Multiple nozzles inclined in a clockwise direction are fixedly installed on the outer side of the hollow disc.

[0017] The technical effects and advantages of this invention are as follows: This invention incorporates a liquid filling unit, which allows the flexible corrugated pipe to expand inside the water tank and fill the tank cavity. This causes the level of a small amount of disinfectant solution inside the tank to rise continuously, immersing the area to be disinfected. This ensures effective disinfection while reducing the amount of disinfectant solution used, lowering processing costs, and reducing the time required for disinfectant solution input and output, thereby improving processing efficiency.

[0018] This invention incorporates a liquid filling unit, which allows the flexible corrugated pipe to unfold inside the water tank, forming a container for preparing disinfectant. This facilitates direct preparation of disinfectant inside the water tank without corroding it. It also eliminates the need for a separate plastic mixing tank for manual preparation of disinfectant, and allows for larger single-use volumes, reducing the need for multiple preparations and further improving processing efficiency.

[0019] This invention incorporates a driving unit and a mixing unit, so that after the driving unit drives the dispensing and filling unit to unfold, it can synchronously drive the two sets of mixing units inside the dispensing and filling unit. This allows the two sets of mixing units to move the initially mixed stock solution and water in a zigzag direction, thereby achieving rapid and uniform mixing of the stock solution and water.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] This invention provides, for example Figures 1-7 The secondary water supply treatment device shown includes a secondary water supply storage unit 1, a liquid filling unit 2 is provided at the top of the inner cavity of the secondary water supply storage unit 1, and a liquid supply unit 3 is provided on the right side of the secondary water supply storage unit 1. The secondary water supply storage unit 1 is also provided with a drive unit 4 for driving the liquid filling unit 2 to unfold. The liquid filling unit 2 is provided with two sets of mixing units 5 with opposite stirring directions and a spraying unit 6 for spraying bactericide.

[0024] like Figure 2As shown, the secondary water supply storage unit 1 includes a water tank 11. The side of the water tank 11 is provided with observation windows (not shown) distributed vertically to view the position of each component inside the water tank 11. A tank cover 12 is fixedly installed on the top of the water tank 11. A lower clearance hole 13 is opened in the center of the top of the tank cover 12. A flexible corrugated pipe 23 is located inside the lower clearance hole 13. An outer shell 14 is fixedly installed on the top of the tank cover 12. An upper clearance hole 15 is opened on the top of the outer shell 14. A suction pipe 34 is located inside the upper clearance hole 15. A water inlet pipe 16 is fixedly installed through the top of the front of the water tank 11. A water outlet pipe 17 is fixedly installed through the bottom of the front of the water tank 11. A sewage pipe 18 is fixedly installed through the bottom of the left side of the water tank 11.

[0025] By setting up the above structure, the water tank 11 can be emptied through the water outlet pipe 17 before the periodic sterilization treatment. After the sterilization is completed, domestic water can be introduced into the water tank 11 again through the water inlet pipe 16 and stored in the water tank 11.

[0026] like Figure 3 As shown, the liquid filling unit 2 includes a top plate 21 fixedly installed on the top of the inner side of the outer shell 14. The top plate 21 has a liquid inlet hole 22. The bottom of the top plate 21 is fixedly connected to a flexible corrugated tube 23 in a folded state. The tube is made of PFA and will not be corroded by the bactericide concentrate. The bottom end of the flexible corrugated tube 23 is fixedly connected to a bottom plate 24. The bottom of the bottom plate 24 has mounting grooves 25 on both sides. The bottom of the bottom plate 24 is fixedly connected to a counterweight bottom cover 26.

[0027] By setting the above structure, when the lifting frame 44 descends, the bottom plate 24 is driven to descend by the limiting pin 46. When the bottom plate 24 descends, it stretches the flexible corrugated pipe 23, thereby causing the flexible corrugated pipe 23, which is in a folded state, to be stretched and unfolded downwards. During the unfolding process of the flexible corrugated pipe 23, a negative pressure is generated inside it. The negative pressure is transmitted to the inside of the raw material container 31 through the suction pipe 34. The water inside the raw material container 31 is sucked into the configuration container composed of the flexible corrugated pipe 23 and the bottom plate 24 through the suction pipe 34.

[0028] It should be noted that the top of the top plate 21 is also provided with a wiring hole for the power cord of the output pump 62 to pass through, and the wiring hole and the power cord are sealed with waterproof glue.

[0029] like Figure 4 As shown, the liquid supply unit 3 includes a raw material container 31 with an opening at the top. A water injection pipe 32 is fixedly installed through the bottom right side of the raw material container 31. A suction pipe 34 is inserted into the inside of the raw material container 31 and fixedly connected to the inside of the liquid inlet hole 22. Fixing brackets 33 are fixedly sleeved on the top and bottom of the outer side of the raw material container 31. Both fixing brackets 33 are fixedly installed on the right side of the water tank 11.

[0030] By setting up the above structure, water for preparing the disinfectant can be continuously injected into the raw material container 31 through the water injection pipe 32. At the same time, the disinfectant concentrate can be added into the raw material container 31 through the top opening of the raw material container 31. Then the concentrate enters the preparation container through the suction pipe 34 along with the water.

[0031] like Figure 5 As shown, the drive unit 4 includes a guide shaft 41 fixedly disposed vertically on the right side of the inner cavity of the water tank 11 and a lead screw 42 rotatably nested on the left side of the inner cavity of the water tank 11 via ball bearings. The top end of the lead screw 42 is connected to a motor 43 fixedly disposed on the top of the water tank 11. A lifting frame 44 is slidably sleeved on the outside of the guide shaft 41 in the vertical direction via linear bearings. The lifting frame 44 is sleeved on the outside of the lead screw 42 and is rotatably connected to the lead screw 42. Threaded sleeves 45 are rotatably nested on both sides of the top of the lifting frame 44 via ball bearings. Limit pins 46 are slidably inserted through the top front and top rear sides of the lifting frame 44 in the vertical direction. The bottom ends of the two limit pins 46 are fixedly connected to the top of the base plate 24. A return spring 47 located between the base plate 24 and the lifting frame 44 is sleeved on the outside of any one of the limit pins 46.

[0032] By setting the above structure, the motor 43 drives the lifting frame 44, which is guided by the guide shaft 41, to descend continuously through the lead screw 42. When the lifting frame 44 descends, it drives the base plate 24 to descend through the limit pin 46. When the base plate 24 can no longer descend, the limit pin 46 rises relative to the lifting frame 44, and the return spring 47 is compressed by the lifting frame 44. At the same time, the two threaded sleeves 45 move downward on the outside of the two threaded rods 51 respectively.

[0033] like Figure 6 As shown, any set of mixing units 5 includes a threaded rod 51 and a rotating shaft 52 that are rotatably nested on the top of the base plate 24 via ball bearings in the vertical direction. The threaded rod 51 is driven and disposed inside the adjacent threaded sleeve 45. A rotating disk 53 is fixedly connected to the top of the rotating shaft 52. A stirring plate 54 is fixedly disposed on the top of the rotating disk 53. A drive wheel 55 is fixedly sleeved on the bottom outer side of the threaded rod 51. A driven wheel 56 is fixedly sleeved on the bottom outer side of the rotating shaft 52. A synchronous belt 57 is driven and sleeved on the outer side of the drive wheel 55 and the driven wheel 56. The drive wheel 55, the driven wheel 56 and the synchronous belt 57 are all located inside the adjacent mounting groove 25.

[0034] By setting up the above structure, when the two threaded sleeves 45 move downwards on the outside of the two threaded rods 51 respectively, the two threaded rods 51 rotate in different directions under the drive of the two threaded sleeves 45, that is, one threaded rod 51 rotates clockwise and the other threaded rod 51 rotates counterclockwise. When the two threaded rods 51 rotate, they drive the two rotating shafts 52 to rotate through the corresponding driving wheel 55, driven wheel 56 and synchronous belt 57. The two rotating shafts 52 drive the two stirring plates 54 to rotate in different directions in the preparation container through the two rotating disks 53, thereby causing the initially mixed stock solution and water in the preparation container to move in a figure-eight direction, so as to achieve rapid and uniform mixing of stock solution and water to produce disinfectant.

[0035] like Figure 7 As shown, the spraying unit 6 includes a liquid outlet pipe 61 fixedly installed inside the base plate 24. Both the liquid outlet pipe 61 and the suction pipe 34 are equipped with one-way valves. An output pump 62 is fixedly connected to the top of the liquid outlet pipe 61. A hollow disc 63 is rotatably sleeved on the bottom of the outer side of the liquid outlet pipe 61 through a ball bearing. The hollow disc 63 is rotatably nested on the bottom of the counterweight base cover 26 through a ball bearing. Multiple nozzles 64 are fixedly installed on the outer side of the hollow disc 63 in a clockwise direction. The clockwise installation method allows the liquid to generate a reverse thrust when the multiple nozzles 64 spray disinfectant, thereby causing the hollow disc 63 to drive the multiple nozzles 64 to rotate continuously, so that all parts inside the water tank 11 can be flushed by disinfectant.

[0036] By setting up the above structure, the output pump 62 can draw the disinfectant from the container after starting, and then input it into the hollow plate 63 through the liquid outlet pipe 61. Finally, multiple nozzles 64 spray it onto the inner wall of the water tank 11, which cleans the inner wall of the water tank 11 and disinfects it at the same time. The disinfectant is then discharged through the drain pipe 18 after use.

[0037] The specific working process of this invention is as follows: Before the regular sterilization process, the water tank 11 is emptied through the water outlet pipe 17, and then the valves on the water outlet pipe 17 and the sewage pipe 18 are closed. At this time, the motor 43 drives the lifting frame 44, which is guided by the guide shaft 41, to descend continuously through the lead screw 42. At the same time, water for preparing the sterilizing agent is continuously injected into the raw material container 31 through the water injection pipe 32. When the lifting frame 44 descends, it drives the base plate 24 to descend through the limiting pin 46. When the base plate 24 descends, it stretches the flexible corrugated pipe 23, thereby causing the flexible corrugated pipe 23, which is in a folded state, to be stretched and unfolded downwards. During the unfolding process of the flexible corrugated pipe 23, a negative pressure is generated inside it. The negative pressure is transmitted to the inside of the raw material container 31 through the suction pipe 34. The water inside the raw material container 31 is sucked into the configuration container composed of the flexible corrugated pipe 23 and the base plate 24 through the suction pipe 34. During this process, the disinfectant concentrate is added into the raw material container 31 through the top opening of the raw material container 31, and then the concentrate enters the preparation container through the suction pipe 34 along with the water. As the base plate 24 descends due to the lifting frame 44, the hollow disc 63 moves down synchronously via the counterweight bottom cover 26. As the hollow disc 63 continues to descend, it eventually fits against the bottom of the inner cavity of the water tank 11. At this point, the flexible corrugated pipe 23 is fully extended, and the base plate 24 can no longer descend. Water is no longer injected into the raw material container 31 through the water injection pipe 32. Subsequently, as the lifting frame 44 continues to descend, the limit pin 46 rises relative to the lifting frame 44, and the return spring 47 is compressed by the lifting frame 44. At the same time, the two threaded sleeves 45 move downward on the outside of the two threaded rods 51 respectively. Two threaded rods 51 rotate in different directions under the drive of two threaded sleeves 45 (one threaded rod 51 rotates clockwise and the other threaded rod 51 rotates counterclockwise). When the two threaded rods 51 rotate, they drive the two rotating shafts 52 to rotate through the corresponding driving wheel 55, driven wheel 56 and synchronous belt 57. The two rotating shafts 52 drive the two stirring plates 54 to rotate in different directions in the preparation container through the two rotating disks 53. This causes the initially mixed stock solution and water in the preparation container to move in a figure-eight direction, so as to achieve rapid and uniform mixing of the stock solution and water to produce a disinfectant. The motor 43 drives the lifting frame 44 to move upward and reset via the lead screw 42. During this process, the output pump 62 is started simultaneously and the valve on the drain pipe 18 is opened. After the output pump 62 starts, it draws the disinfectant from the container and then inputs it into the hollow plate 63 through the liquid outlet pipe 61. Finally, multiple nozzles 64 spray it onto the inner wall of the water tank 11, which cleans the inner wall of the water tank 11 and disinfects it. The disinfectant is then output through the drain pipe 18 after use. After the lifting frame 44 moves up and resets, the valve on the drain pipe 18 is closed and water is injected into the raw material container 31 again through the water injection pipe 32. At the same time, the motor 43 drives the lifting frame 44 to descend again through the screw 42, thereby realizing the second preparation of disinfectant in the preparation container. Motor 43 drives the lifting frame 44 to move upward again via lead screw 42 and starts output pump 62, thereby inputting disinfectant into water tank 11. Then, motor 43 drives the lifting frame 44 to move downward again via lead screw 42 until hollow plate 63 moves to the bottom of the inner cavity of water tank 11 (not in contact with the bottom of the inner cavity of water tank 11). At this time, motor 43 is stopped. The aforementioned lifting frame 44 moves down again, causing the flexible corrugated pipe 23 to unfold. The flexible corrugated pipe 23 then enters the disinfectant inside the water tank 11, while simultaneously discharging the disinfectant outwards, thereby causing the level of the disinfectant to rise continuously until the area inside the water tank 11 that needs to be disinfected is completely immersed in the disinfectant. After standing for half an hour to an hour, the disinfectant is discharged through the drain pipe 18, and then clean water is introduced through the inlet pipe 16 to rinse the remaining disinfectant inside the water tank 11. After rinsing is completed, the motor 43 drives the lifting frame 44 to move up and reset via the lead screw 42, while the flexible corrugated pipe 23 returns to its folded state. Then the motor 43 is stopped, and domestic water can be input into the water tank 11 again through the water inlet pipe 16 and stored in the water tank 11.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
