Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a single-coil heat exchange water storage tank for heating. Background Technology

[0002] A heat exchange storage tank is a storage device used for heating or domestic hot water. It achieves heat exchange through an internal single spiral coil. Existing heat exchange storage tanks are mainly divided into two types: one for residential or commercial heating and the other for domestic hot water supply. This utility model is mainly aimed at improving the equipment for residential or commercial heating.

[0003] Existing heat exchange storage tanks require multiple binding wires to secure the heat exchange coils during use, followed by placement and welding of the entire assembly into the tank. Cleaning the tank interior relies primarily on magnesium rods. Furthermore, the heat exchange uniformity is poor when heating water at different levels within the tank. These factors lead to the following problems during equipment use: 1. When fixing the heat exchange coils of the existing equipment, multiple binding wires are required before the whole unit is placed into the tank and welded. When cleaning or replacing the coils, the binding wires or the original welded positions need to be removed, which makes the replacement and cleaning time-consuming, labor-intensive and difficult to operate.

[0004] 2. In the existing equipment, magnesium rods are mainly used for cleaning. However, after a period of use, magnesium rods themselves will accumulate a lot of impurities. Moreover, magnesium rods are not easy to clean the dirt deposited at the bottom of the tank, which can easily cause the water quality to become dirty and the outlet to become blocked.

[0005] 3. In existing equipment, the heat exchange uniformity is poor.

[0006] Based on this, the present invention provides a single-coil heat exchange water storage tank for heating to solve the above problems. Utility Model Content

The two can be threaded together or engaged with a snap-fit ​​and locking mechanism. A heat exchange coil 3 is installed inside the tank body 1. A positioning mechanism for positioning the heat exchange coil 3 is provided inside the tank body 1. The positioning mechanism includes a sludge collection plate 4, which is fixedly connected to the inner wall of the tank body 1. Specifically, the sludge collection plate 4 is a circular plate that matches the inner wall of the tank body 1. The sludge collection plate 4 is fixed at the bottom of the inner wall of the tank body 1. A continuous weld is provided between the outer periphery and the inner wall of the tank 1 to serve as the bottom of the container and prevent leakage. Multiple grooves 5 are provided on the sludge collection plate 4, preferably along the radius of the sludge collection plate 4. The grooves 5 are strip-shaped holes penetrating the sludge collection plate 4. A turntable 6 is rotatably connected to the bottom of the sludge collection plate 4, and the two can rotate coaxially relative to each other. A rotation drive structure is provided on the turntable 6. The rotation drive structure can be a handle fixed to the turntable 6, or a toothed structure as shown in the figure.

Alternatively, the turntable can be made into a gear or fixedly connected to a coaxial gear, and the turntable 6 can be rotated by a hydraulic motor driving the gear. A rotating sealing ring is preferably provided between the outer ring of the turntable 6 and the sludge collection plate 4 to reduce minor water leakage caused by the groove and clearance fit. The turntable 6 has multiple arc-shaped grooves 7, which are non-penetrating blind holes.

A ratchet 16 is provided in the sludge collection trough 12, and the ratchet 16 is sleeved on the outside of the rotating shaft 13. A ratchet mechanism that cooperates with the ratchet 16 is provided on the rotating shaft 13. The ratchet mechanism is existing technology, such as... Figure 4 It includes a fixed ring fixed to the rotating shaft 13. The fixed ring is hinged with ratchet teeth and a stop bar that limits the ratchet teeth in one direction. It will not be described in detail here. The outer wall of the ratchet 16 is fixed with a scraper 17 that cooperates with the sludge collection tank 12. The scraper at the bottom of the scraper 17 abuts against the bottom wall of the sludge collection tank 12.

[0027] Furthermore, the outer wall of the rotating shaft 13 is fixed with multiple layers of spiral agitator 19, and preferably, when the rotating shaft 13 rotates in the direction that the ratchet mechanism drives the ratchet 16 to rotate, the spiral agitator 19 drives the water flow to a downward trend.

[0028] Furthermore, the top of the rotating shaft 13 is rotatably connected to the bottom of the sleeve 21, the outer wall of the sleeve 21 is fixedly connected to the can cover 2, and the top of the sleeve 21 is fixedly connected to the medicine inlet pipe 20, so that the medicine inlet pipe 20 is connected to the top of the rotating shaft 13.

[0029] Furthermore, the bottom of the sludge collection tank 12 is provided with a sludge outlet 22, which is connected to one end of the sludge pipe 23.

The turntable 6 is provided with a clearance hole that cooperates with the sludge pipe 23 to prevent interference between the two when rotating.

[0030] Furthermore, the drive motor 18 is fixed to the bottom of the tank body 1, and a bottom box 24 with the same diameter as the tank body 1 is fastened to the outside of the drive motor 18. Heat dissipation holes can be provided on the bottom box 24 as needed.

[0031] Furthermore, a water outlet 25 is provided on the top of the tank body 1, and a water inlet 26 is provided on the bottom of the tank body 1, which is connected to a water circulation device through a pipe.

[0033] Furthermore, a magnesium rod 29 is detached and installed on the tank body 1 and placed inside the tank body 1.

[0034] The working process of this utility model is as follows: Open the tank cover 2, put the heat exchange coil 3 into the tank body, and let the heat inlet 27 and heat outlet 28 extend out of the tank body from the corresponding holes on the tank body 1. Rotate the turntable 6 to change the intersection position of the arc groove 7 and the slide groove 5, so as to change the position of the slider 8 in the slide groove 5, so that the slider 8 drives the support rod 9 to make a linear back-and-forth movement in the slide groove 5. After the support rod 9 moves a certain distance in the slide groove 5, the support rod 9 abuts against the inner wall of the heat exchange coil 3 to achieve clamping and fixation. After fixing, fasten the pressure ring 11 on the top of the support rod 9. The bottom of the pressure ring 11 is inserted into the inner wall of the support rod 9 to achieve fixation. At this time, the water in the tank body 1 is heated normally. Water enters the tank body 1 from the water inlet 26 at the bottom of the tank body 1. The medium with heat, such as steam, enters from the heat inlet 27 of the heat exchange coil 3. At this time, the drive motor 18 is connected to the power supply. The rotating shaft 13 is driven to start rotating, which in turn drives the spiral agitator 19 on the rotating shaft 13 to start rotating, causing the water flow direction in the tank 1 to change. Hot water and cold water in the tank 1 are constantly mixed and heated. The heated water is discharged through the outlet 25 on the tank 1, and the medium that loses heat in the heat exchange coil 3 flows out from the heat outlet 28. During cleaning, the agent enters the inner cavity of the rotating shaft 13 through the inlet pipe 20 and flows into the sludge collection tank 12 through the outlet hole 14 on the rotating shaft 13. At this time, the drive motor 18 is turned on and reverses, and the ratchet mechanism on the rotating shaft 13 meshes with the ratchet 16, driving the scraper 17 on the ratchet 16 to rotate. The scraper 47 scrapes and cleans the dirt in the sludge collection tank 12. The spiral agitator 19 drives the water flow downward, flushing the sludge collection tank 12 and the dirt together, which then flows out through the drain outlet 22 and the drain pipe 23.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
