Description

Technical Field

[0001] This invention relates to the field of heating equipment technology, and more particularly to a heating facility. Background Technology

[0002] During the cold season, heating facilities have become crucial equipment for maintaining ambient temperature and improving comfort in homes, offices, and industrial settings. Currently, most mainstream heating facilities on the market use water as the heat transfer medium. They heat circulating water through heaters, and then use the hot water circulation to achieve heat transfer. These water-based heating facilities are widely used in various scenarios due to their high heat transfer efficiency and relatively low operating costs. However, existing hydronic heating systems generally face the core problem of scale formation and accumulation during long-term use. Because circulating water contains a certain amount of calcium and magnesium ions, these ions easily combine with carbonate ions in the water during heating to form insoluble precipitates such as calcium carbonate and magnesium hydroxide (i.e., scale). This scale gradually adheres to the heat exchange surfaces of the heater, the inner walls of the pipes, and the inside of the water tank. On the one hand, the thermal conductivity of scale is much lower than that of metal heat exchange components, significantly reducing the heat exchange efficiency of the heater and leading to increased energy consumption. Simultaneously, to reach the preset heating temperature, the heater needs to operate under continuous high load, shortening the equipment's lifespan. On the other hand, scale accumulation on the inner walls of the pipes narrows the water flow channels, increasing water circulation resistance. This not only affects the hot water circulation speed and reduces the stability of the heating effect, but in severe cases, it can also cause pipe blockage, leading to equipment failure, increased maintenance costs, and downtime risks. To address the scale problem, existing technologies have proposed several solutions, such as adding chemical descaling agents to circulating water and using ion exchange resins to remove calcium and magnesium ions. However, the use of chemical descaling agents has certain limitations: long-term addition can lead to chemical residues inside the equipment, potentially corroding metal parts and shortening equipment lifespan. Furthermore, the regular replenishment of chemical agents increases operating costs and poses certain environmental risks. Ion exchange resins, on the other hand, require regular regeneration or replacement, which is cumbersome, has high maintenance costs, and generates wastewater during resin regeneration, which is environmentally unfriendly and fails to meet the requirements for long-term, stable, and low-cost scale control.

[0003] Therefore, a heating system needs to be designed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a heating facility that can efficiently remove calcium and magnesium ions from water, optimize water flow, and simplify maintenance operations, thereby improving the heat exchange efficiency, operational stability, and service life of the equipment, reducing usage and maintenance costs, and meeting heating needs in various scenarios.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A heating device includes a water tank, a main pipe, a gas storage tank, and multiple heaters. The upper end of the water tank is connected to a rectangular box. The outlet ends of the multiple heaters are connected to the top space of the rectangular box. A calcium-magnesium ion separation component is installed inside the rectangular box. The calcium-magnesium ion separation component includes a placement box fixedly connected to the inner wall of the rectangular box. The bottom of the placement box has a water outlet. A spiral tube is installed inside the rectangular box. Both ends of the spiral tube are connected to rotary joints. The upper end of the upper rotary joint is connected to the water outlet. The rear inner wall of the rectangular box is fixedly connected to the water outlet. A fixed block is fixedly connected to the rectangular box, and a drain pipe is fixedly connected through the fixed block. The upper end of the drain pipe is connected to a rotary joint located below. A drive motor is installed at the upper end of the rectangular box. The output shaft of the drive motor extends into the rectangular box and is fixedly connected to a vertical rod. The vertical rod is connected to the spiral tube through a transmission assembly. After the water flows into the rotating spiral tube, the rotation of the spiral tube itself will be superimposed on the original flow inertia of the water flow, forming a double centrifugal effect of "rotational centrifugal force + inertial centrifugal force of water flowing along the tube", which promotes the formation of calcium and magnesium ions into flocculent matter.

[0006] Preferably, the main pipe is connected to the inlets of multiple heaters via branch pipes, the gas storage tank is connected to the gas inlet of the heater via a gas supply pipe, the gas storage tank is filled with propane gas, a circulation pump and a return water pump are installed on the front side of the water tank, a water supply pipe is connected to the rear side of the water tank, the inlet of the return water pump is connected to a return water pipe, the outlet of the return water pump is connected to the bottom space of the water tank, the inlet of the circulation pump is connected to the bottom space of the water tank, and the outlet of the circulation pump is connected to the main pipe via a bend.

[0007] Preferably, the water tank is provided with a flow-through component, which includes a disc disposed inside the water tank. Two flow-through ports are symmetrically arranged on the front and rear sides of the disc, and a flow-through plate is provided in each of the two flow-through ports. The top of the flow-through plate is lower than the top of the disc.

[0008] Preferably, the disc is provided with a partition, which divides the internal space of the disc into two semi-circular areas. The outlet of the drain pipe is located above the rear semi-circular area. A rotating rod is fixedly connected to the lower end of the disc. Two support legs and a rectangular box are fixedly connected to the lower end of the water tank. The lower end of the rotating rod extends into the rectangular box and is connected to a gear through a one-way bearing. A second pneumatic rod is fixedly connected to the left inner wall of the rectangular box. A moving block is fixedly connected to the telescopic end of the second pneumatic rod. A rack that meshes with the gear is fixedly connected to the right side of the moving block.

[0009] Preferably, the two flow plates are slidably connected to the inner wall of the corresponding flow port, and a plurality of third pneumatic rods are fixedly connected to the lower end of the disc. The telescopic ends of every two cooperating third pneumatic rods are fixedly connected to a fixing plate, and the two fixing plates are fixedly connected to the corresponding flow plates.

[0010] Preferably, an iron filter screen is placed at the bottom of the rear semi-circular area, and a replacement assembly is provided on the right side of the water tank. The replacement assembly includes two slide rails fixedly connected to the right side of the water tank, and a slider is slidably connected to both slide rails. Two strip rods are fixedly connected to the left side of the slider, and two electromagnets are fixedly connected to the lower ends of the two strip rods. The lower ends of the two electromagnets located on the rear side are attracted to the iron filter screen. The lower end of the slider is connected to the lower end of the moving block through a connecting rod.

[0011] Preferably, the water tank has a rectangular opening on the right side, and a strip groove at the lower end of the rectangular opening. Two first pneumatic rods are fixedly connected to the bottom of the strip groove. The telescopic ends of the two first pneumatic rods are fixedly connected to a sealing plate. A rubber sealing ring is provided between the sealing plate and the inner wall of the rectangular opening.

[0012] Preferably, the transmission assembly includes sprockets mounted on the vertical rod and the spiral tube, and the two sprockets are connected by a chain drive.

[0013] The present invention has the following beneficial effects: Compared with existing technologies, this invention sets up a calcium and magnesium ion separation component. A drive motor drives the vertical rod to rotate, and then a transmission component drives the spiral tube to rotate. When water flows into the rotating spiral tube, a dual centrifugal effect is formed, which combines the rotational centrifugal force and the inertial centrifugal force of the water flowing along the tube. This effectively promotes the formation of calcium and magnesium ions into flocs, thereby achieving effective separation of calcium and magnesium ions in circulating water. It eliminates the need for chemical agents and frequent resin maintenance. This not only effectively reduces scale formation, ensures the heat exchange efficiency of the heater and the smooth flow of the pipeline, and extends the service life of the equipment, but is also more energy-efficient and environmentally friendly, reducing the cost of use and maintenance. Compared with the prior art, the present invention sets up a flow-through component in the water tank. The core function of the flow-through port is to guide the water flow into the water tank in a flow-through manner, so that most of the calcium and magnesium ion flocs are retained in the disc under the guidance of gravity and water flow, and the flocs are prevented from spreading to other areas of the water tank with the water flow, causing secondary pollution or pipe blockage. Compared with existing technologies, this method uses a partition to divide the internal space of the disc into two semi-circular areas, front and back. Driven by a second pneumatic rod, the rotating rod drives the disc to rotate through the meshing of gears and racks. When the disc rotates to the alternating intersection of the front and back semi-circular areas, it can achieve a zonal synergy effect of "filtering newly generated flocculent matter with the iron filter screen in the rear area while centrally processing the flocculent matter remaining in the front area." This completely solves the problem that flocculent matter filtration and cleaning are difficult to perform simultaneously in traditional facilities. It ensures continuous interception of flocculent matter during water circulation and avoids the trouble of downtime for cleaning, further improving the continuity and stability of equipment operation. Compared with existing technologies, the third pneumatic rod allows the diffuser plate to slowly move downwards after the disc rotates, completely draining the water in the front area into the water tank. Simultaneously, the replaceable components allow a new iron filter to be placed in the rear semi-circular area after each disc rotation, while the iron filter in the front semi-circular area can be removed for cleaning. This eliminates the need to disassemble numerous parts to replace and clean the metal mesh and lint, significantly reducing maintenance difficulty and cost.

[0014] In summary, this invention, through the deep synergy of calcium and magnesium ion separation components, diffused flow components, zoned rotating structures, and easily replaceable components, constructs a complete solution encompassing "high-efficiency descaling, zoned filtration, simultaneous cleaning, and convenient maintenance." Compared to traditional heating systems, this invention not only fundamentally solves core problems such as scale formation, difficulty in cleaning flocculent matter, and cumbersome maintenance, but also ensures long-term stable operation of the equipment, improves heat exchange efficiency and heating effect, while reducing usage and maintenance costs. It also boasts energy-saving and environmentally friendly advantages, making it suitable for various scenarios such as homes, offices, and industries. It possesses significant technological innovation and extremely high practical and promotional value. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] Reference Figures 1-7 A heating facility includes a water tank 1, a main pipe 11, a gas storage tank 8, and multiple heaters 7. The water tank 1 is made of stainless steel, which has good corrosion resistance and heat preservation effect. Its internal volume can be designed according to actual heating needs to ensure that it can store enough circulating water to maintain stable heating. The main pipe 11 and the branch pipes are both high-temperature resistant plastic or metal pipes with smooth inner walls to reduce water flow resistance and scale adhesion. Valves can be installed on the branch pipes as needed to individually control the water inlet flow of the corresponding heater 7, which facilitates equipment maintenance and flow adjustment. The upper end of the water tank 1 is connected to a rectangular box 5, which is integrally formed with the water tank 1. The liquid outlet of the multiple heaters 7 is connected to the top space of the rectangular box 5. A calcium and magnesium ion separation component is installed inside the rectangular box 5. This component includes a placement box 25 fixedly connected to the inner wall of the rectangular box 5, with an outlet at the bottom of the placement box 25. A spiral tube 29, made of copper alloy, is installed inside the rectangular box 5, possessing excellent thermal conductivity and corrosion resistance. Its spiral structure prolongs the residence time of water within the tube, allowing calcium and magnesium ions more time to aggregate and form flocs under a double centrifugal effect. Rotary joints 28 are connected to both the upper and lower ends of the spiral tube 29. The upper end of the upper rotary joint 28 is connected to the outlet. A fixing block 30 is fixedly connected to the rear inner wall of the rectangular box 5, with a drain pipe fixedly connected through the fixing block 30. The upper end of the drain pipe is connected to the lower rotary joint 28. A drive motor 6 is installed at the top of the box 5. The drive motor 6 is a servo motor with adjustable speed. It can adjust the speed according to the content of calcium and magnesium ions in the water flow, thereby changing the rotation speed of the spiral tube 29 and optimizing the double centrifugal effect. The output shaft of the drive motor 6 extends into the rectangular box 5 and is fixedly connected to a vertical rod 26. The vertical rod 26 and the spiral tube 29 are connected by a transmission assembly 27. The transmission assembly 27 includes sprockets set on the vertical rod 26 and the spiral tube 29. The two sprockets are connected by a chain drive. After the water flows into the rotating spiral tube 29, the rotation of the spiral tube 29 itself will be superimposed on the original flow inertia of the water flow, forming a double centrifugal effect of "rotational centrifugal force + inertial centrifugal force of water flowing along the tube", which promotes the formation of calcium and magnesium ions into flocs.

[0019] The main pipe 11 is connected to the inlets of multiple heaters 7 via branch pipes and is equipped with a microcomputer device for controlling the heating temperature of the heaters 7. The gas storage tank 8 is connected to the gas inlet of the heaters 7 via a gas supply pipe 9. The gas storage tank 8 is filled with propane gas. A circulation pump 2 and a return water pump 3 are installed on the front side of the water tank 1, and a water supply pipe 21 is connected to the rear side of the water tank 1. External heating equipment and a water supply pump are installed. The water supply pipe 21 is connected to the inlet of the water supply pump, and the outlet of the water supply pump is connected to the... The heating equipment is connected, and the inlet of the return water pump 3 is connected to the return water pipe 4. The return water pipe is connected to the outlet of the heating equipment. The outlet of the return water pump 3 is connected to the bottom space of the water tank 1. The inlet of the circulation pump 2 is connected to the bottom space of the water tank 1. The outlet of the circulation pump 2 is connected to the main pipe 11 through the bend 12. The water tank 1 is equipped with a temperature control component and a control box. The control box is equipped with a PLC control program. The temperature control component monitors the temperature in the water tank 1 and controls the operation of the circulation pump 2 and the water supply pump according to the temperature.

[0020] The water tank 1 is equipped with a flow-through component, which includes a disc 31 installed inside the water tank 1. Two flow-through ports 37 are symmetrically arranged on the front and rear sides of the disc 31. Each of the two flow-through ports 37 is equipped with a flow-through plate 36. The top of the flow-through plate 36 is lower than the top of the disc 31.

[0021] The disc 31 is equipped with a partition 32, which divides the internal space of the disc 31 into two semi-circular areas. The outlet of the drain pipe is located above the rear semi-circular area. A rotating rod 33 is fixedly connected to the lower end of the disc 31. Two support legs 22 and a rectangular box 23 are fixedly connected to the lower end of the water tank 1. The lower end of the rotating rod 33 extends into the rectangular box 23 and is connected to a gear 38 through a one-way bearing. A second pneumatic rod 24 is fixedly connected to the left inner wall of the rectangular box 23. A moving block 40 is fixedly connected to the telescopic end of the second pneumatic rod 24. A rack 39 that meshes with the gear 38 is fixedly connected to the right side of the moving block 40. The one-way bearing ensures that when the rack 39 moves to the left, the gear 38 drives the rotating rod 33 to rotate. When the rack 39 moves to the right, the gear 38 cannot drive the rotating rod 33 to rotate.

[0022] Among them, two overflow plates 36 are slidably connected to the inner wall of the corresponding overflow port 37, and multiple third pneumatic rods 34 are fixedly connected to the lower end of the disc 31. The telescopic ends of every two cooperating third pneumatic rods 34 are fixedly connected to a fixing plate 35, and the two fixing plates 35 are fixedly connected to the corresponding overflow plates 36.

[0023] The rear semi-circular area has an iron filter screen placed at its inner bottom. A replacement assembly is located on the right side of the water tank 1. The replacement assembly includes two slide rails 17 fixedly connected to the right side of the water tank 1. A slider 18 is slidably connected to both slide rails 17. Two strip rods 19 are fixedly connected to the left side of the slider 18. Two electromagnets 20 are fixedly connected to the lower ends of the two strip rods 19. In the initial state, the electromagnet 20 located on the rear side is energized and attracts a new iron filter screen. The two electromagnets 20 located on the front side are de-energized. The lower ends of the two electromagnets 20 located on the rear side attract the iron filter screen. The lower end of the slider 18 is connected to the lower end of the moving block 40 through a connecting rod 16. A rectangular opening is provided on the right side of the water tank 1. A strip groove 13 is provided at the lower end of the rectangular opening. Two first pneumatic rods 14 are fixedly connected to the inner bottom of the strip groove 13. The telescopic ends of the two first pneumatic rods 14 are fixedly connected to a sealing plate 15. A rubber sealing ring is provided between the sealing plate 15 and the inner wall of the rectangular opening.

[0024] The functional principle of this invention can be explained by the following operation: opening the gas storage tank 8 allows the propane gas inside to be stably delivered to the heater 7 through the gas supply pipe 9, and at the same time starting the water supply process of the main pipe 11—the main pipe 11 flows the water in the water tank 1 to the water inlet of each heater 7 through the branch pipe, providing a water source for the heating process. Inside the heater 7, propane gas burns and releases heat to heat the incoming water. The heated water flows out from the outlet of the heater 7 and first flows into the top space of the rectangular box 5. At this time, the drive motor 6 at the top of the rectangular box 5 is started. The drive motor 6 drives the vertical rod 26 at the end of the output shaft to rotate. The vertical rod 26 drives the spiral tube 29 to rotate synchronously through the transmission assembly 27 composed of sprockets and chains. The water flows out from the outlet of the box 25 inside the rectangular box 5 and enters the rotating spiral tube 29 through the upper rotary joint 28. Under the combined action of the "rotational centrifugal force" generated by the rotation of the spiral tube 29 itself and the "inertial centrifugal force" generated by the water flowing along the inner wall of the spiral tube 29, a double centrifugal effect is formed, which promotes the rapid aggregation of calcium and magnesium ions in the water to form flocculents. Finally, the water flows through the lower rotary joint 28 into the drain pipe and is transported to the disc 31 in the water tank 1. Water flows from the drain pipe into the semi-circular area on the rear side of the disc 31, separated by the partition 32. At this time, the third pneumatic rod 34 is kept in its initial state, positioning the overflow plate 36 in the upper-middle part of the overflow port 37. The water slowly accumulates within the disc 31. When the water level is higher than the top of the overflow plate 36, it flows into the main body of the water tank 1 through the overflow port 37. This overflow design significantly slows down the water flow, preventing most of the calcium and magnesium ion flocs in the water from entering the water tank under gravity. Instead, they remain in the semi-circular area on the rear side of the disc 31, achieving initial separation of the flocs from the water flow and preventing them from spreading into subsequent pipes or equipment and causing blockages. The heated water stored in the water tank 1 is continuously injected into external heating equipment to meet actual heating needs. The low-temperature water after use by the heating equipment is returned to the water tank 1 through the return pipe 4 by the return pump 3, forming a basic cycle of heating and water return. When the water temperature in water tank 1 decreases due to continuous heating or return water replenishment, the temperature control component in water tank 1 will monitor the temperature change in real time. Once the temperature is lower than the preset threshold, the temperature control component will immediately transmit a signal to the controller. After receiving the signal, the controller will trigger the circulation pump 2 to run. The circulation pump will extract the low-temperature water from the water tank and deliver it to the main pipe 11 through the bend pipe 12. It will then be distributed to each heater 7 through the branch pipe for secondary heating. The heated water will be descaled in the rectangular box 5 according to the above process and then returned to water tank 1 to ensure that the water temperature in water tank 1 is always maintained in a stable range and to ensure the heating effect. Every so often, the second pneumatic rod 24 inside the rectangular box 23 is activated. The second pneumatic rod 24 retracts and drives the moving block 40 to move to the left. The moving block 40 drives the rotating rod 33 to rotate through the meshing transmission of the rack 39 and the gear 38, thereby causing the disc 31 to rotate 180° synchronously, realizing the position switching of the front and rear semi-circular areas. The "front area" where the original flocculent material was stored (the position after switching) is moved to the side to be cleaned, and the "front area" where the original empty material was stored (the position before switching) is moved to the rear side, continuing to receive the descaling water flow delivered from the drain pipe, ensuring that the filtration of flocculent material is uninterrupted. After the disc 31 completes its rotation, the third pneumatic rod 34 corresponding to the overflow port of the front area to be cleaned is activated. The third pneumatic rod 34 retracts, causing the fixed plate 35 to move down, which in turn causes the overflow plate 36 to slowly move down along the inner wall of the overflow port 37 until the overflow port 37 is fully open. At this time, the water remaining in the front area is completely discharged into the water tank 1 through the overflow port 37, ensuring that all the flocculent matter is retained on the iron filter screen at the bottom of the area, preparing for subsequent cleaning.

[0025] When starting the replacement component, first control the first pneumatic rod 14 to retract, causing the sealing plate 15 to move downward and open the rectangular opening. Simultaneously, the second pneumatic rod 24 pulls the moving block 40, which, through the connecting rod 16, drives the slider 18 to slide to the left along the slide rail 17. The strip rod 19 on the left side of the slider 18 moves synchronously. Since, initially, the two electromagnets 20 located at the rear are energized and attract clean iron filter screens, while the electromagnets 20 located at the front are de-energized, the movement of the slider 18 delivers the new iron filter screen to the rear... Above the semi-circular area, when the slider 18 moves to the set position, the two electromagnets 20 on the rear side are de-energized and the two electromagnets 20 on the front side are energized. The clean iron filter falls into the semi-circular area on the rear side, and the iron filter in the semi-circular area on the front side will be attracted to the electromagnet. Then, the second pneumatic rod 24 is stretched, which drives the moving block 40 and the rack 39 to reset, thereby bringing the metal filter with flocculent material out to the outside. Then, the first pneumatic rod 14 is stretched, and the sealing plate 15 is used to close the rectangular opening again. It is worth mentioning that, because a one-way bearing is provided between the rotating rod 33 and the gear 38, when the rack 39 moves to the right to reset, the rotation of the gear 38 will not drive the rotating rod 33 to rotate. However, when the rack 39 moves to the left, the rotation of the gear 38 can drive the rotating rod 33 to rotate.

[0026] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
