Description

Technical Field

[0001] This utility model relates to the field of hot water anti-scaling circulation pump technology, specifically a circulation pump for preventing scale blockage in a hot water circulation system. Background Technology

[0002] A hot water circulation pump is a mechanical device used to circulate and transport hot water. It is widely used in heating systems, industrial processes, and various other applications requiring hot water circulation. Hot water circulation pumps play a vital role in modern life, providing reliable hot water supply solutions for homes and businesses with their efficient and stable performance.

[0003] At high temperatures, calcium carbonate and magnesium ions in water combine to form insoluble calcium carbonate and magnesium carbonate. These substances precipitate out of the water and adhere to the container, forming limescale.

[0004] During the circulation of hot water through a water pump, a layer of scale will form on the inner wall of the pump pipe due to the continuous flow of water. This scale will have a certain impact on the normal operation and service life of the hot water circulation pump. Scale has an extremely low thermal conductivity, much lower than that of metal materials, which will hinder heat transfer during the heating or cooling process of the hot water circulation pump, thereby reducing the heat transfer efficiency. The presence of scale will cause the heat transfer surface of the hot water circulation pump to overheat, which may lead to safety accidents such as bulging, cracking, and pipe bursting. When the water pump channel is severely blocked by scale, it will make the disassembly and cleaning of the pump extremely difficult, increasing the workload and time required for maintenance personnel. Utility Model Content

[0005] The purpose of this invention is to provide a circulation pump for a hot water circulation system that prevents scale buildup and clogging, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hot water circulation system anti-scaling and anti-clogging pump includes a hot water circulation pump and a non-powered anti-scaling and anti-clogging device. The hot water circulation pump includes a pump body, a drive motor, and a base. The output end of the drive motor is connected to the pump shaft of the pump body. The top of the base is connected to the bottom outer wall of the pump body and the drive motor. A hot water circulation inlet is provided at the end of the pump body away from the drive motor, and a hot water circulation outlet is provided at the top of the pump body. A hot water circulation inlet pipe is threadedly connected to the inlet of the hot water circulation inlet. The non-powered anti-scaling and anti-clogging device is located on the outer circumferential wall of the hot water circulation inlet pipe.

[0008] As a preferred embodiment of this utility model, the non-powered anti-scaling and anti-clogging device includes a fixing component, an adjusting component, and a non-powered strong magnet component. Multiple sets of the non-powered strong magnet component are provided, and the non-powered strong magnet components are evenly distributed on the outer circumferential wall of the hot water circulation inlet pipe. Each set of the non-powered strong magnet component includes at least two strong magnet blocks, and the two strong magnet blocks are connected to each other through a connecting rod. There are more than three sets of the non-powered strong magnet component.

[0009] As a preferred embodiment of this utility model, the fixing component includes a first semi-circular fixing ring and a second semi-circular fixing ring. One end of the first semi-circular fixing ring is rotatably connected to one end of the second semi-circular fixing ring via a rotating shaft. The other end of the first semi-circular fixing ring is engaged with the other end of the second semi-circular fixing ring via a fixing clip. The first semi-circular fixing ring and the second semi-circular fixing ring are combined to form a circular structural ring. Fixing rods are evenly connected on the circular structural ring, and a fixing threaded hole is provided through the inside of the fixing rod.

[0010] As a preferred embodiment of this utility model, the adjusting assembly includes an adjusting threaded rod, which is threaded through and connected inside each fixed rod. The end of the adjusting threaded rod located inside the circular structural ring is connected to the end of the connecting rod away from the strong magnet block, and the other end of the adjusting threaded rod is connected to an adjusting threaded knob.

[0011] As a preferred embodiment of this utility model, a fastening bolt is threaded onto the circular structural ring located at the top of each of the fixed rods, and the bottom of the fastening bolt abuts against the top of the adjusting threaded rod.

[0012] As a preferred embodiment of this utility model, the fixing rod is provided in three or more sets.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In view of the problems mentioned in the background art, the anti-scaling circulation pump of the hot water circulation system of this application combines a non-powered strong magnet assembly, a fixing assembly and an adjusting assembly to effectively prevent scale, improve the operating efficiency and service life of the hot water circulation pump, and at the same time reduce maintenance costs and safety risks.

[0015] 2. The non-powered anti-scaling and anti-clogging device is installed on the outer circumferential wall of the hot water circulation inlet pipe. It uses the magnetic field generated by a strong magnet to prevent the formation and accumulation of scale.

[0016] 3. When hot water flows through the hot water circulation inlet pipe, the magnetic field generated by the non-powered strong magnet component acts on calcium, magnesium and other ions in the water, causing their crystal form to change, making it less likely to form hard scale on the inner wall of the pipe. At the same time, due to the effect of the magnetic field, the scale that has already formed may be gradually dissolved or become loose and easily carried away by the water flow.

[0017] 4. The distance between the strong magnet and the hot water circulation inlet pipe can be adjusted according to actual needs by adjusting the component to achieve the best anti-scaling effect;

[0018] 5. Due to the reduction of scale, the heat transfer surface of the hot water circulation pump is cleaner, and heat transfer is smoother, thereby improving heat transfer efficiency; it reduces overheating problems caused by scale, and lowers the risk of safety accidents such as bulging, cracking, and pipe bursting; due to the reduction of scale, the disassembly and cleaning of the hot water circulation pump becomes easier, reducing the workload and time required for maintenance personnel; it can operate without electricity, meeting the requirements of energy conservation and environmental protection.

Detailed Implementation

[0025] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example

[0026] Please see Figure 1-4 This utility model provides a technical solution: a hot water circulation pump for preventing scale buildup in a hot water circulation system, comprising a hot water circulation pump 1 and a non-powered anti-scale buildup device 2. The hot water circulation pump 1 includes a pump body 11, a drive motor 12, and a base 13. The output end of the drive motor 12 is connected to the pump shaft of the pump body 11. The top of the base 13 is connected to the bottom outer wall of the pump body 11 and the drive motor 12. A hot water circulation inlet 111 is provided at the end of the pump body 11 away from the drive motor 12, and a hot water circulation outlet 112 is provided at the top of the pump body 11. Hot water is connected to the inlet of the hot water circulation inlet 111 by a thread. The circulating water inlet pipe 113 has a non-powered anti-scaling and anti-clogging device 2 located on the outer circumferential wall of the hot water circulating water inlet pipe 113. The non-powered anti-scaling and anti-clogging device 2 includes a fixing component 21, an adjusting component 22, and a non-powered strong magnet component 23. Multiple sets of non-powered strong magnet components 23 are provided and are evenly distributed on the outer circumferential wall of the hot water circulating water inlet pipe 113. Each set of non-powered strong magnet components 23 includes at least two strong magnet blocks 231. The two strong magnet blocks 231 are connected through a connecting rod 232. There are more than three sets of non-powered strong magnet components 23.

[0027] It should be noted that in this embodiment, the non-powered anti-scaling and anti-clogging device 2 is installed on the outer circumferential wall of the hot water circulation inlet pipe 113. The magnetic field generated by the strong magnet is used to prevent the formation and accumulation of scale. When hot water flows through the hot water circulation inlet pipe 113, the magnetic field generated by the non-powered strong magnet component 23 acts on the calcium, magnesium and other ions in the water, causing their crystal form to change, making it less likely to form hard scale on the inner wall of the pipe. At the same time, due to the effect of the magnetic field, the scale that has already formed may also be gradually dissolved or become loose, and easily carried away by the water flow, preventing scale from staying inside the pump body 11 and causing blockage.

[0028] Pump body 11 is responsible for the extraction and circulation of hot water. Drive motor 12 provides power to drive pump body 11 to work. Base 13 supports and fixes pump body 11 and drive motor 12 to ensure stable operation of equipment. Hot water circulation inlet 111 is located at the end of pump body 11 away from drive motor 12 and is used to connect to hot water source. Hot water circulation outlet 112 is located at the top of pump body 11 and outputs circulated hot water. Hot water circulation inlet pipe 113 is connected to inlet by thread and is the channel for hot water to enter pump body 11. In this embodiment, the non-powered anti-scaling and anti-clogging device 2 is installed on the outer circumferential wall of hot water circulation inlet pipe 113. The magnetic field generated by strong magnet block 231 can affect the physical state of calcium and magnesium ions in water, prevent them from combining to form hard scale, and may also cause the scale that has been formed to become loose and easily carried away by water flow.

[0029] Furthermore, multiple sets of non-powered strong magnet components 23 are evenly distributed on the outer circumferential wall of the hot water circulation inlet pipe 113 to ensure uniform magnetic field action and prevent scale formation in all directions.

[0030] Furthermore, the device requires no external energy supply and relies on its own structural design to achieve scale prevention, which is both energy-saving and environmentally friendly. Because scale accumulation is reduced, the cleaning and maintenance of the hot water circulation pump becomes simpler, extending the service life of the equipment.

[0031] Please see Figure 3 and 4 The fixing component 21 includes a first semi-circular fixing ring 211 and a second semi-circular fixing ring 212. One end of the first semi-circular fixing ring 211 is rotatably connected to one end of the second semi-circular fixing ring 212 via a rotating shaft. The other end of the first semi-circular fixing ring 211 is engaged with the other end of the second semi-circular fixing ring 212 via a fixing clip 214. The first semi-circular fixing ring 211 and the second semi-circular fixing ring 212 are combined to form a circular structure ring. Fixing rods 213 are evenly connected on the circular structure ring. The fixing rods 213 are internally threaded. The adjustment assembly 22 includes an adjustment threaded rod 221, which is threaded through and connected to the inside of each fixed rod 213. The end of the adjustment threaded rod 221 located inside the circular structural ring is connected to the end of the connecting rod 232 away from the strong magnet block 231. The other end of the adjustment threaded rod 221 is connected to the adjustment threaded knob 222. A fastening bolt 223 is threadedly connected to the circular structural ring at the top of each fixed rod 213. The bottom of the fastening bolt 223 abuts against the top of the adjustment threaded rod 221. There are three or more sets of fixed rods 213.

[0032] It should be noted that, in this embodiment, the fixing component 21 includes a first semi-circular fixing ring 211, a second semi-circular fixing ring 212, a rotating shaft, a fixing clip 214, and a fixing rod 213. These components together form an adjustable circular structure ring, which is used to stably install the anti-scaling device on the outer circumferential wall of the hot water circulation inlet pipe 113. The first semi-circular fixing ring 211 and the second semi-circular fixing ring 212 are rotatably connected by the rotating shaft and are engaged and fixed by the fixing clip 214 to form a stable circular structure ring. The fixing rod 213 is evenly connected to the circular structure ring and has a fixing threaded hole inside for installing and fixing the adjusting component 22.

[0033] The adjustment assembly 22 includes an adjustment threaded rod 221, an adjustment threaded knob 222, and a fastening bolt 223. These components allow adjustment of the position or magnetic field strength of the anti-scaling device to adapt to different working conditions. The adjustment threaded rod 221 passes through the interior of each fixed rod 213 and is connected to the connecting rod 232 inside the circular structural ring. The adjustment threaded knob 222 is connected to the other end of the adjustment threaded rod 221, and the user can adjust the magnetic field position by rotating it. The fastening bolt 223 is threaded onto the circular structural ring at the top of each fixed rod 213 and abuts against the top of the adjustment threaded rod 221 to fix the adjustment position. The non-powered strong magnet assembly 23 is provided in multiple sets, each set including at least two strong magnet blocks 231, which are connected through the connecting rod 232. The end of the connecting rod 232 is connected to the adjustment threaded rod 221. The strong magnet blocks 231 are evenly distributed on the outer circumferential wall of the hot water circulation inlet pipe 113 to ensure uniform magnetic field action and prevent scale formation in all directions.

[0034] The magnetic field generated by the strong magnet can affect the physical state of calcium and magnesium ions in the water, preventing them from combining to form scale. At the same time, it may also loosen the scale that has already formed, making it easier to be carried away by the water flow. Multiple sets of strong magnet components 23 are evenly distributed on the outer circumferential wall of the water inlet pipe to ensure that the magnetic field acts evenly and prevents scale formation in all directions. This device does not require an external energy supply and achieves its anti-scale function by relying on its own structural design. It is both energy-saving and environmentally friendly. Because the accumulation of scale is reduced, the cleaning and maintenance of the hot water circulation pump becomes simpler and the service life of the equipment is extended.

[0035] The anti-scaling and anti-clogging circulation pump of this hot water circulation system is ingeniously designed, effectively solving the scale problem in a non-powered manner. It not only improves the efficiency and safety of the hot water circulation system, but also reduces operating and maintenance costs, making it an innovative technology in the field of hot water circulation systems.

[0036] The working process of this utility model:

[0037] During use, the pump body 11 is responsible for the extraction and circulation of hot water, and the drive motor 12 provides power to drive the pump body 11 to work. The base 13 supports and fixes the pump body 11 and the drive motor 12 to ensure stable operation of the equipment. The non-powered anti-scaling and clogging device 2 is installed on the outer circumferential wall of the hot water circulation inlet pipe 113. The magnetic field generated by the strong magnet block 231 can affect the physical state of calcium and magnesium ions in the water, preventing them from combining to form hard scale. At the same time, it may cause the scale that has already formed to become loose and easily carried away by the water flow, thus preventing scale formation in all aspects. It does not require external energy supply and achieves the anti-scaling function by relying on its own structural design, which is both energy-saving and environmentally friendly. Due to the reduction of scale accumulation, the cleaning and maintenance of the hot water circulation pump becomes simpler, and the service life of the equipment is extended.
