Description

Technical Field

[0001] This utility model relates to the field of stainless steel water tank technology, and specifically discloses a spray-type self-cleaning stainless steel water tank. Background Technology

[0002] Stainless steel water tanks are widely used in domestic water supply, industrial circulating water, and heat exchange systems due to their corrosion resistance, high strength, and good hygiene. They are often used in conjunction with coils to achieve heating, cooling, or constant temperature functions. However, during long-term use, the inside of the water tank is prone to scale buildup due to the deposition of water impurities and the growth of microorganisms. In particular, the surface of the coils is prone to the adhesion of scale, rust, and organic residue.

[0003] As a core component of heat exchange, the surface dirt of the coils can significantly increase thermal resistance, reduce heat transfer efficiency, and lead to increased energy consumption. Deposits on the inner wall of the water tank and in the gaps between the coils can easily breed bacteria and algae, contaminating the stored water. Existing cleaning methods require periodic shutdowns and rely on manual entry into the water tank for scrubbing or high-pressure water jet rinsing. This is not only labor-intensive and involves a harsh working environment, but also makes manual cleaning even more difficult for large water tanks or equipment installed in confined spaces. Furthermore, frequent shutdowns for maintenance can affect the continuous operation of the system. Therefore, a spray-type self-cleaning stainless steel water tank is needed to solve the above problems. Utility Model Content

Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0021] Please see Figure 1-4 A spray-type self-cleaning stainless steel water tank includes a tank body 1 and a coil 2 disposed inside the tank body 1. A movable spray mechanism is disposed inside the tank body 1. The movable spray mechanism includes a lead screw 3 rotatably connected inside the tank body 1. A sliding sleeve 5 is threadedly connected to the outer wall of the lead screw 3. A U-shaped tube 7 is fixedly connected to the outer wall of the sliding sleeve 5. The left and right ends of the inner wall of the U-shaped tube 7 are respectively connected to a first drain pipe 8 and a second drain pipe 9. Multiple evenly distributed first nozzles 10 are installed on the outer wall of the U-shaped tube 7. Multiple evenly distributed second nozzles 12 are installed on the opposite side of two adjacent first drain pipes 8 and second drain pipes 9. Multiple evenly distributed third nozzles 11 are installed on the right end of the first drain pipe 8. Multiple evenly distributed fourth nozzles 13 are installed on the left end of the second drain pipe 9.

[0022] In this embodiment: the lead screw 3 rotates, causing the sliding sleeve 5 on the outer wall of the lead screw 3 to move linearly along the lead screw 3, thereby driving the U-shaped tube 7 on the outer wall of the sliding sleeve 5 to move synchronously. The cleaning water enters through the water inlet pipe on the outer wall of the U-shaped tube 7, and is diverted to the first drainage pipe 8 and the second drainage pipe 9 through the U-shaped tube 7. The first nozzle 10 on the outer wall of the U-shaped tube 7 sprays towards the bottom and side wall of the box 1 to flush away the deposits on the inner wall and the dirt in the corners. The second nozzle 12 on the opposite side of the first drainage pipe 8 and the second drainage pipe 9, which are inserted between adjacent coils 2, sprays directly towards the outer wall of the coil 2 to remove surface scale, etc. The third nozzle 11 on the right end of the first drainage pipe 8 and the fourth nozzle 13 on the left end of the second drainage pipe 9 spray towards the right side wall and the left side wall inside the box 1, respectively, to cover the dead corner between the coil 2 and the box wall.

[0023] As a technical optimization of this utility model, a motor 14 with its output end fixedly connected to the lead screw 3 is installed on the outer wall of the housing 1.

[0024] In this embodiment, the lead screw 3 can be driven to rotate by the motor 14.

[0025] As a technical optimization of this utility model, a limiting rod 4 is fixedly connected inside the box 1, a limiting block 6 is slidably connected to the outer wall of the limiting rod 4, and the outer wall of the limiting block 6 is fixedly connected to the U-shaped tube 7.

[0026] In this embodiment, the axial rotation of the U-shaped tube 7 can be prevented by the cooperation of the limiting rod 4 and the limiting block 6.

[0027] As a technical optimization of this utility model, the first nozzle 10 sprays towards the bottom and side wall of the housing 1, the second nozzle 12 sprays towards the outer wall of the coil 2, the third nozzle 11 sprays towards the right side wall inside the housing 1, and the fourth nozzle 13 sprays towards the left side wall inside the housing 1.

[0028] In this embodiment: the bottom and front and rear side walls of the housing 1 can be cleaned by the first nozzle 10, the outer wall of the coil 2 can be cleaned by the second nozzle 12, and the left and right side walls inside the housing 1 can be cleaned by the third nozzle 11 and the fourth nozzle 13.

[0029] As a technical optimization of this utility model, the outer wall of the U-shaped tube 7 is connected to a water inlet pipe.

[0030] In this embodiment: the water inlet pipe is connected to an external water source pipe, so that clean water can be introduced into the U-shaped pipe 7.

[0031] As a technical optimization of this utility model, the bottom of the box 1 is connected to a drain pipe with a valve.

[0032] In this embodiment, the sewage inside the tank 1 can be easily discharged through the drain pipe.

[0033] As a technical optimization of this utility model, the first drainage tube 8 and the second drainage tube 9 are inserted between two adjacent rows of coils 2.

[0034] In this embodiment, the first drainage tube 8 and the second drainage tube 9 are inserted between two adjacent rows of coils 2, which facilitates cleaning of the outer wall of the coils 2.

[0035] The working principle and usage process of this utility model are as follows: When the cleaning program is started, the motor 14 drives the lead screw 3 to rotate, causing the sliding sleeve 5 on the outer wall of the lead screw 3 to move linearly along the lead screw 3, thereby driving the U-shaped tube 7 on the outer wall of the sliding sleeve 5 to move synchronously. At the same time, the limiting rod 4 guides and constrains the U-shaped tube 7 through the limiting block 6 to ensure stable movement and ensure coverage of the entire length of the coil 2 and the inside of the box 1. The cleaning water enters through the water inlet pipe on the outer wall of the U-shaped tube 7, and is diverted through the U-shaped tube 7 to the first drainage pipe 8 and the second drainage pipe 9. The first nozzle 10 on the outer wall of the U-shaped tube 7 sprays water onto the bottom and side walls of the box 1 to flush away the deposits on the inner wall and corners. To remove surface scale and other dirt, the second nozzle 12, located opposite the first drain pipe 8 and the second drain pipe 9 intersecting between adjacent coils 2, sprays directly towards the outer wall of the coil 2. The third nozzle 11 at the right end of the first drain pipe 8 and the fourth nozzle 13 at the left end of the second drain pipe 9 spray towards the right and left walls of the tank 1 respectively to cover the dead corners between the coil 2 and the tank wall. During the cleaning process, the dirt that falls off sinks to the bottom of the tank 1 with the water flow and is discharged through the drain pipe with a valve at the bottom to prevent secondary adhesion. After cleaning, the motor 14 reverses to drive the lead screw 3 to reset, and the moving spray mechanism returns to the initial position to wait for the next instruction.
