Description

Technical Field

[0001] This utility model relates to the field of water tank technology, and more specifically, to a water tank with good heat preservation effect. Background Technology

[0002] Insulated water tanks are water tanks with special industrial and insulation materials added to the interlayer to maintain a certain temperature to meet domestic or industrial needs. Insulated water tanks can be divided into stainless steel insulated water tanks, pressurized insulated water tanks, and fiberglass insulated water tanks, depending on the materials used in their processing.

[0003] The insulation material of existing water tanks is mostly wrapped in layers on the outside. Because the insulation material is wrapped on the outside of the water tank, it is necessary to remove all the insulation material when the water tank is inspected and maintained. After the inspection and maintenance is completed, new insulation material needs to be replaced, which increases the cost of water tank maintenance and repair. Utility Model Content

[0031] Please see Figures 1-7 A water tank with good heat preservation effect includes a water tank body 1 and an insulated box 2. Multiple support bases 3 are fixedly connected to the bottom of the interior of the insulated box 2. The exterior of the insulated box 2 is covered with insulation material 4. The water tank body 1 is placed inside the insulated box 2. Positioning grooves 24 are provided at the top of the support bases 3. Multiple positioning posts 25 are fixedly connected to the bottom of the water tank body 1, and these posts 25 are inserted into the positioning grooves 24 to facilitate positioning of the water tank body 1. Multiple support blocks 26 are evenly fixedly connected inside the insulated box 2 for support. A first vacuum cavity 5 is formed between the water tank body 1 and the insulated box 2. A drain pipe 6 is connected to the bottom of the water tank body 1, and a first valve 7 is installed on the drain pipe 6. A circular groove 8 is provided at the bottom of the insulated box 2, and a conical groove 9 is provided at the bottom of the circular groove 8. The drain pipe 6 passes through the interior of the circular groove 8 to the exterior of the insulated box 2. The insulated box 2 has a sealing mechanism at the bottom corresponding to the conical groove 9. A sealing cover 10 is installed at the top of the insulated box 2. A second vacuum chamber 14 is provided inside the sealing cover 10. The bottom of the sealing cover 10 has an opening 15 that communicates with the first vacuum chamber 5 to ensure the sealing cover 10 has a tight sealing and heat insulation effect. A first sealing gasket 16 is fixedly connected to the bottom of the sealing cover 10 at the position corresponding to the insulated box 2 to ensure the sealing between the sealing cover 10 and the insulated box 2. A second sealing gasket 17 is fixedly connected to the bottom of the sealing cover 10 at the position corresponding to the water tank body 1 to ensure the sealing between the sealing cover 10 and the water tank body 1. A water inlet pipe 11 is connected to the top of the water tank body 1 and extends to the upper side of the water tank body 1. A vacuum tube 12 is connected to the side of the insulated box 2, and a second valve 13 is installed on the vacuum tube 12.

[0032] Specifically, the water tank body 1 is placed inside the insulation box 2, and the insulation box 2 is sealed with a sealing cover 10. Then, it is connected to an external vacuuming device through a vacuum tube 12, and a vacuum is drawn inside the first vacuum chamber 5. Since the second vacuum chamber 14 is connected to the first vacuum chamber 5 through a port 15, the second vacuum tube is also evacuated when the first vacuum chamber 5 is evacuated, thus ensuring that the first vacuum chamber 5 and the second vacuum chamber 14 are in a vacuum state, thereby improving the heat preservation effect of the water tank body 1. When the water tank body 1 needs to be inspected and maintained, the first valve 7 and the sealing cover 10 are removed, and then the water tank body 1 is pulled out from the inside of the insulation box 2 for inspection and maintenance. Compared with the existing technology, this avoids the need to clean off the layers of firmly pasted insulation material 4 before inspecting and maintaining the water tank body 1, and avoids the need to paste new insulation material 4 layer by layer on the outside of the water tank body 1, thus reducing the cost of inspection and maintenance of the water tank body 1.

[0033] Please see Figure 1 and Figure 7 The sealing mechanism includes two L-shaped seats 18, an adjusting plate 19, and a sealing ring 20. The adjusting plate 19 is slidably engaged with the drain pipe 6, and the sealing ring 20 is sleeved on the outside of the drain pipe 6. Both L-shaped seats 18 are fixedly connected to the insulation box 2. Both L-shaped seats 18 are threaded with screws 21. The side end of the screws 21 contacts the side end of the adjusting plate 19. A handle 22 is fixedly connected to the side end of the screws 21 to ensure the sealing of the connection between the drain pipe 6 and the insulation box 2. Four fixing rods 23 are fixedly connected to the bottom of the insulation box 2. All four fixing rods 23 are slidably engaged with the adjusting plate 19 to limit the position of the adjusting plate 19.

[0034] Specifically, by rotating the two screws 21 clockwise, the two screws 21 move relative to the two L-shaped seats 18 towards the side closer to the insulation box 2. The two screws 21 push the adjusting plate 19 to move, squeezing the sealing ring 20 into the conical groove 9, so that the side end of the sealing ring 20 is pressed against the side end of the drain pipe 6, ensuring the sealing of the connection between the drain pipe 6 and the insulation box 2.

[0035] In summary, when using the overall equipment:

[0036] Insert the water tank body 1 into the interior of the insulation box 2, so that multiple positioning pins 25 are respectively inserted into the interior of multiple positioning slots 24, and make the drain pipe 6 pass through the interior of the circular groove 8, the sealing ring 20, and the adjusting plate 19. Then, install the first valve 7 on the drain pipe 6, and then turn the two screws 21 clockwise. The two screws 21 move relative to the two L-shaped seats 18 towards the side closer to the insulation box 2. The two screws 21 push the adjusting plate 19 to move, squeezing the sealing ring 20 into the interior of the conical groove 9, so that the side end of the sealing ring 20 is in contact with the side end of the drain pipe 6. Tighten the drain pipe 6 to seal the connection between it and the insulation box 2. Then install the sealing cover 10 on the insulation box 2. At this time, the first sealing gasket 16 and the second sealing gasket 17 are in a compressed state to ensure the sealing of the connection between the water tank body 1, the insulation box 2 and the sealing cover 10. Then connect to the external vacuuming equipment through the vacuum pipe 12. Then open the second valve 13 and start the vacuuming equipment. Vacuum the first vacuum chamber 5 and the second vacuum chamber 14 through the vacuuming equipment. After the vacuuming is completed, close the second valve 13 and the vacuuming equipment.

[0037] When the water tank body 1 needs to be inspected, open the second valve 13, and then open the sealing cover 10. You can observe the area around the water tank body 1 through the gap in the first vacuum chamber 5 to perform a preliminary inspection. When the water tank body 1 needs to be pulled out of the insulation box 2 for inspection, close the first valve 7, and then turn the screw 21 counterclockwise to separate the screw 21 from the adjusting plate 19. Then, use a pry bar to pry the adjusting plate 19 to separate the sealing ring 20 from the insulation box 2. At the same time, pull the water tank body 1 upward to pull the water tank body 1 out of the insulation box 2 for careful inspection and maintenance.
