Description

Technical Field

[0001] This utility model belongs to the field of direct drinking water technology, and in particular relates to a direct drinking water raw water storage tank with a cleaning function. Background Technology

[0002] Piped drinking water systems provide users with healthy, high-quality, and convenient drinking water services, and their application is becoming increasingly widespread. The production process of piped drinking water systems requires a water storage device, namely a raw water storage tank. Because the raw water (mainly municipal tap water) contains trace amounts of organic and inorganic impurities, these impurities accumulate on the bottom and inner walls of the storage tank over long-term use. This not only increases the lifespan of the downstream filters in the drinking water system but also negatively impacts the quality of the produced water, significantly affecting the overall hygiene of piped drinking water. Currently, the cleaning process for raw water storage tanks involves manually rinsing the inside of the tank through the manhole using a handheld high-pressure water gun. This operation presents the following problems: First, it requires manual operation, resulting in low efficiency, and the inconsistent distance between the nozzle and the inner wall of the tank leads to unstable cleaning results; second, manual operation carries the risk of personnel falling into the manhole, affecting the safety of the operation. Summary of the Invention

[0043] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] Example 1:

[0045] like Figures 1 to 8As shown, a direct drinking water raw water storage tank with a cleaning function includes: a tank body 1, with a support leg 101 fixedly installed on the outer side of the lower end of the tank body 1; a top cover 2, which closes the upper opening of the tank body 1 and has an installation hole; and a cleaning assembly, which includes a vertical pipe 5, with a horizontal pipe 501 perpendicularly arranged to the lower end of the vertical pipe 5, a nozzle 8 provided at the end of the horizontal pipe 501 away from the vertical pipe 5, and a nozzle 8 provided on the side wall of the horizontal pipe 501. The vertical pipe 5 is installed inside the installation hole.

[0046] A drain pipe 102 is fixedly installed at the lower end of the tank body 1, and the drain pipe 102 is connected to the inside of the tank body 1. A drain valve is connected to the drain pipe 102. A water outlet pipe 103 is fixedly installed on the side wall of the tank body 1, and the water outlet pipe 103 is connected to the inside of the tank body 1. A water outlet valve is connected to the water outlet pipe 103. A water inlet pipe 201 connected to the inside of the tank body 1 is fixedly installed on the upper cover 2. A water inlet solenoid valve is connected to the water inlet pipe 201. A manhole pipe 202 connected to the inside of the tank body 1 is provided on the upper cover 2. A cover plate 204 is provided corresponding to the manhole pipe 202. The cover plate 204 is detachably connected to the manhole pipe 202. The cover plate 204 is a transparent structural component.

[0047] The lower end of the top cover 2 is fixed with a first flange, and the upper end of the tank body 1 is fixed with a second flange. The first flange and the second flange are detachably connected by bolts.

[0048] The top cover 2 is equipped with a detection tube 203, and the detection tube 203 is equipped with an ab float switch 3. The control box of the ab float switch 3 is detachably connected to the detection tube 203. The lower float of the ab float switch 3 is higher than the water outlet pipe 103 to ensure that there is always water in the water outlet pipe 103. The upper float of the ab float switch 3 is lower than the top cover 2 to prevent water from flowing out from the gap between the top cover 2 and the tank body 1.

[0049] The AB float switch 3 is used to control the opening and closing of the inlet solenoid valve. When the water level in tank 1 drops to the middle of the lower float, contacts A1 and A2 of the switch automatically close, the inlet solenoid valve opens, and water is added to tank 1. When the water level rises to the middle of the upper float, contacts A1 and A2 of the switch automatically open, and the inlet solenoid valve closes. This cycle repeats continuously, ensuring that tank 1 maintains the set water level and achieves uninterrupted water supply. This is existing technology and will not be elaborated further. The AB float switch 3 uses, but is not limited to, the existing Shangmei water tower tank water level automatic controller float switch. The inlet solenoid valve uses, but is not limited to, the existing Keyence solenoid valve.

[0050] A connecting pipe 4 is fixedly installed at the upper end of the vertical pipe 5. The connecting pipe 4 is connected to the outlet of the high-pressure water pump via a flexible hose. The flexible hose is connected to the water supply pipe via a cleaning solenoid valve. The water supply pipe is connected to the outlet of the high-pressure water pump (if the pressure of the raw water pipe is high enough, both the inlet pipe and the supply pipe can be connected to the raw water pipe). The outer diameter of the connecting pipe 4 is larger than the outer diameter of the vertical pipe 5. An installation pipe 205 corresponding to the installation hole is fixedly installed on the upper cover 2. The inner diameter of the installation pipe 205 matches the outer diameter of the connecting pipe 4. The connecting pipe 4 is connected to the flexible hose via a swivel joint.

[0051] The drain pipe 102 is coaxially aligned with the mounting hole; a guide rod 6 corresponding to the drain pipe 102 is fixed at the lower end of the vertical pipe 5. The diameter of the guide rod 6 is smaller than the inner diameter of the drain pipe 102. A baffle 601 is fixed at the upper end of the guide rod 6. The diameter of the baffle 601 is larger than the inner diameter of the drain pipe 102. The baffle 601 is a structural component made of polytetrafluoroethylene. The baffle 601 limits the vertical pipe 5, ensuring the distance between the spray head and the bottom of the tank 1, thereby ensuring the cleaning effect. The drain pipe 102 plays a positioning and guiding role during the rotation of the vertical pipe 5.

[0052] The connecting pipe 4 is provided with a corresponding insert plate 7. The insert plate 7 has a slot 701 that matches the vertical pipe 5. When the cleaning component is in standby mode (at this time the raw water storage tank is in working mode), the vertical pipe 5 is located inside the slot 701. The width of the insert plate 7 is greater than the inner diameter of the mounting pipe 205. The insert plate 7 is located between the connecting pipe 4 and the mounting pipe 205.

[0053] In other embodiments, the width of the slot 701 is greater than the diameter of the vertical tube 5 and less than the outer diameter of the connecting tube 4. The connecting tube 4 is provided with a plurality of annular grooves 401, which are evenly arranged along the length of the connecting tube. When the insert plate is inserted into the annular grooves 401 at different positions, the height of the nozzle is different.

[0054] The inner edge of the slot 701 near the opening is chamfered, which serves as a guide as the vertical rod enters the slot 701.

[0055] Both the tank body 1 and the top cover 2 are structural components made of stainless steel, and in this embodiment, 304 stainless steel is used.

[0056] Nozzle 8 is a stainless steel high-pressure fan-shaped nozzle. This nozzle may employ, but is not limited to, the existing MEG high-pressure fan-shaped nozzle from Changyuan Spray Company. The fan-shaped spray pattern emitted by the stainless steel high-pressure fan-shaped nozzle is parallel to the axis of the horizontal pipe 501 and perpendicular to the ground. The axis of the stainless steel high-pressure fan-shaped nozzle is parallel to the circumference of the vertical pipe 5. Nozzles 8 are provided at both ends of the horizontal pipe 501. The distance between the nozzle 8 and the inner wall of the tank 1 is 10-15 cm. When the baffle 601 contacts the bottom of the tank 1, the distance between the nozzle 8 on the side wall of the horizontal pipe 501 and the bottom of the tank 1 is 10-20 cm.

[0057] Work process:

[0058] When implementing this solution, after a period of use, if the inside of tank 1 needs cleaning, the raw water storage tank is in operation. The drain valve is opened, the insert plate 7 limits the connection pipe 4, and the horizontal pipe 501 is higher than tank 1. The insert plate 7 is pulled out to release the limit on the connection pipe 4, allowing the connection pipe 4 to be inserted into the installation pipe 205. The high-pressure water pump is turned on, and the nozzle 8 on the horizontal pipe 501 sprays a high-pressure water jet to clean the inner wall of tank 1. After rotating the connection pipe 4 two turns, the height of the connection pipe 4 is lowered, and then rotated two more turns, continuing until the baffle 601 limits the connection pipe 4 to a point where it cannot descend further (e.g., ...). Figure 1 As shown, the raw water storage tank is in the cleaning state. Rotate the connecting pipe 45 times to clean the bottom inside the tank 1. The sewage is discharged through the drain pipe 102.

[0059] Compared to the traditional method of manually cleaning the inside of the tank 1 by holding a high-pressure water gun through the manhole, the cleaning can be completed without opening the manhole by lowering and rotating the vertical pipe 5 and spraying high-pressure water from the nozzle 8. This improves work efficiency and ensures the safety of the operation.

[0060] The distance between the nozzle 8 and the inner wall of the tank 1 is fixed to ensure the cleaning effect.

[0061] Example 2:

[0062] like Figure 9 As shown, a direct drinking water raw water storage tank with a cleaning function includes: a tank body 1, a drain pipe 102 fixedly installed at the lower end of the tank body 1, the drain pipe 102 communicating with the inside of the tank body 1, and a drain valve connected to the drain pipe 102; an upper cover 2, the upper cover 2 sealing the upper opening of the tank body 1, an inlet pipe 201 fixedly installed on the upper cover 2 communicating with the inside of the tank body 1, and an inlet solenoid valve connected to the inlet pipe 201; and a cleaning assembly, the cleaning assembly being connected to the water supply pipe through the cleaning solenoid valve.

[0063] The cleaning component is a horn-shaped cleaning head 9, which is connected to the water supply pipe via a cleaning pipe 10. A cleaning solenoid valve is connected to the cleaning pipe 10. The horn-shaped cleaning head 9 adopts, but is not limited to, the existing Jinze Pump Industry 304 stainless steel tank body universal cleaner and horn-shaped 360-degree cleaning head.

[0064] The upper cover 2 is equipped with a detection tube 203, and a corresponding AB float switch 3 is installed on the detection tube 203. The control box of the AB float switch 3 is detachably connected to the detection tube 203. The lower float of the AB float switch 3 is higher than the outlet pipe 103, and the upper float of the AB float switch 3 is lower than the upper cover 2. The AB float switch 3 is used to control the opening and closing of the inlet solenoid valve. An inlet manual valve is connected to the inlet pipe 201, and a cleaning manual valve is connected to the cleaning pipe 10. The inlet solenoid valve is a normally open solenoid valve, and the cleaning solenoid valve is a normally closed solenoid valve. The inlet pipe 201 is connected to the raw water pipe, and the cleaning pipe 10 is connected to the raw water pipe through the water supply pipe (the pressure of the raw water pipe is greater than 0.5 MPa). The cleaning pipe 10 is fixedly connected to the upper cover.

[0065] Normally open and normally closed solenoid valves are electrically connected to the power supply via a driver. The driver and float switch 3 (ab) are electrically connected to the controller. The normally open and normally closed solenoid valves are, but are not limited to, existing Delixi 220V normally open and normally closed solenoid valves. The driver is, but is not limited to, existing Delixi relays. The controller is, but is not limited to, existing Delixi PLC controllers. Float switch 3 (ab) is, but is not limited to, existing Shangmei water tower tank water level automatic controller float switches. The PLC controller collects water level data through float switch 3 (ab). When the water level is lower than the water level in tank 1, dropping to the middle of the lower float, the inlet solenoid valve is open, and water is added to tank 11. When the water level rises to the middle of the upper float, the inlet solenoid valve is energized and closed. This cycle repeats continuously, ensuring that tank 1 always maintains the set water level, achieving uninterrupted water supply.

[0066] When it is necessary to clean tank 1, open the cleaning hand valve and the cleaning solenoid valve. At this time, the water inlet solenoid valve is in the closed state, and the horn-shaped cleaning head 9 sprays 360-degree high-pressure water to clean the inside of tank 1. Compared with the traditional method of manually cleaning the inside of tank 1 by holding a high-pressure water gun through the manhole, cleaning the inner wall of tank 1 through the cleaning assembly can be completed without opening the manhole, which improves work efficiency and ensures the safety of the operation process.
