Technical Field
[0001] This application relates to the technical field of water preheating equipment, and in particular to a water preheating device based on feed production. Background Technology
[0002] In the feed production industry, boilers are the core energy equipment ensuring continuous production. The steam they generate is mainly used for key processes such as feed pelleting, raw material drying, and workshop heating. According to industry statistics, boiler energy consumption accounts for a large portion of the total energy consumption of a feed mill. Among these processes, boiler water heating is one of the core energy-consuming aspects. Boilers need to heat ambient temperature tap water to a saturated steam state. If the incoming water can be preheated before boiler heating, fuel consumption can be directly reduced, and energy utilization efficiency can be improved.
[0003] Currently, feed mills generally use two traditional methods to preheat boiler water: electric heating and gas heating. Although both methods can meet basic preheating requirements, electric heating preheating involves directly inserting electric heating tubes into the water tank or pipes to convert electrical energy into heat energy and transfer it to the boiler water. Gas heating preheating involves heating the heat exchanger with a gas burner and then transferring the heat to the boiler water through the heat exchanger.
[0004] Regarding the aforementioned technologies, the inventors discovered that in long-term operation, electric heating for preheating boiler water suffers from low energy conversion efficiency and high electricity costs. While gas heating can avoid the high electricity costs associated with electric heating, it suffers from high fuel consumption and high safety risks. Both of these methods exhibit significant drawbacks of high energy consumption and high operating costs, which contradicts the development trend of cost reduction, efficiency improvement, and green production in the feed industry. Utility Model Content
[0005] In order to overcome the significant drawbacks of existing methods of preheating boiler water using electric heating and gas heating, which both have high energy consumption and high operating costs, and which contradict the development trend of cost reduction, efficiency improvement and green production in the feed industry, this application provides a water preheating device based on feed production.
[0006] The water preheating device for feed production provided in this application adopts the following technical solution: A water preheating device for feed production includes a support component, a heat exchange component, a water storage tank, and an insulation tank. The support component includes a support frame, inside which the heat exchange component is installed. The heat exchange component includes a water drying bag, which has a long strip structure and is bent and laid flat inside the support frame. One end of the water drying bag is connected to and fixed with a water inlet pipe, which passes through the support frame. A water pump is connected to and fixed with the water inlet pipe, and the other end of the water inlet pipe is connected to and assembled with the water storage tank, which is used to store boiler water. The other end of the water drying bag is connected to and fixed with a drain pipe, which passes through the support frame. The end of the drain pipe is connected to and assembled with the insulation tank, which is used to store preheated boiler water.
[0007] By adopting the above technical solution, the various components of the water preheating device work together to meet the rapid preheating requirements of feed production. The support frame in the support structure provides structural support, ensuring the stability and reliability of the entire device. The water drying bag in the heat exchange component adopts a long strip structure and is bent and laid flat inside the support frame, increasing the contact area with the outside air and improving heat exchange efficiency. The water inlet pipe introduces boiler water from the water storage tank into the water drying bag, and the water flow is directionally driven by the water inlet pump. The drain pipe discharges the preheated boiler water from the water drying bag and transports it to the insulation tank to continuously provide a heat source for the next preheating. The water storage tank is used to store and supply sufficient boiler water to ensure continuous operation of the device. The insulation tank maintains the water temperature through insulation measures to prevent the preheated water temperature from dropping too quickly, thereby ensuring the preheating effect. Overall, this device rapidly increases the temperature of feed water through an efficient heat exchange mechanism, meeting the temperature requirements for feed heating, improving production efficiency and feed quality.
[0008] Optionally, symmetrical vertical support legs are fixed on the bottom surface of the support frame, and multiple ground nails are installed through the bottom of the support legs.
[0009] By adopting the above technical solution, the support frame serves to support the entire device. The symmetrically and vertically fixed legs on its bottom surface increase the stability of the device and prevent it from tipping over due to uneven ground or external forces during use. Ground spikes further reinforce the legs, ensuring that the support frame can be firmly fixed to the ground.
[0010] Optionally, an insulating cotton pad is fixed to the inner wall of the support frame, and the insulating cotton pad is used to keep the sun-drying bag warm.
[0011] By adopting the above technical solution, the insulating cotton pad is attached to the inner wall of the support frame. Its main function is to insulate the water bag, maintain the water temperature, and prevent changes in the external ambient temperature from affecting the water temperature. Combining the functions of the above components, the support frame provides stable support, the legs and ground nails enhance stability, and the insulating cotton pad effectively maintains a constant water temperature inside the water bag, ensuring that the device can continuously provide a suitable heat source under different conditions.
[0012] Optionally, multiple heat-conducting support frames are fixed horizontally and vertically inside the support frame, and these multiple heat-conducting support frames are set in the bending gaps of the water-drying bag.
[0013] By adopting the above technical solution, the support frame is used to support the entire device, and multiple heat-conducting support frames are fixed inside it. These heat-conducting support frames are placed in the bending gaps of the water-drying bag, thereby improving the heat transfer efficiency.
[0014] Optionally, multiple metal heat exchange plates are fixed on the top surface of the heat-conducting support frame, and multiple raised strips are evenly fixed on the upper surface of the multiple metal heat exchange plates.
[0015] By adopting the above technical solution, multiple metal sun-drying plates are fixed on each heat-conducting support frame. The upper surface of these metal sun-drying plates has multiple protruding strips to enhance the contact area with solar energy, thereby absorbing solar energy more effectively.
[0016] Optionally, a heat exchange plate is horizontally arranged in the vertical direction between multiple heat-conducting support frames inside the support frame, and the two ends of the heat exchange plate are fixed to the adjacent heat-conducting support frame through the water-drying bag.
[0017] By adopting the above technical solution, the heat exchange plate is located between the heat-conducting support frame and fixed to the water-drying bag and the heat-conducting support frame at both ends. When solar radiation shines on the metal heat exchange plate, heat is transferred through the metal heat exchange plate to the heat-conducting support frame, and then to the water in the water-drying bag.
[0018] Optionally, the interior of the thermally conductive support frame is filled with thermal insulation cotton.
[0019] By adopting the above technical solution, the interior of the heat-conducting support frame is filled with heat-insulating cotton, which can effectively reduce heat loss and improve the heat exchange efficiency.
[0020] Optionally, a water supply pipe is fixedly connected to the bottom of the insulated tank, and a valve is connected to the water supply pipe. An insulation cotton sleeve is fitted on the outer wall of the insulated tank.
[0021] By adopting the above technical solution, the bottom of the insulated tank is connected to an external water source via a water supply pipe equipped with a valve to control the water supply. The outer wall of the insulated tank is wrapped with an insulating cotton sleeve to maintain the temperature of the internal liquid. When water needs to be supplied to the insulated tank, the valve is opened to allow external water to flow into the tank. The insulating cotton sleeve effectively prevents the influence of the external ambient temperature on the internal liquid, ensuring a stable temperature of the liquid and extending its insulation effect.
[0022] In summary, this application includes at least one of the following beneficial technical effects: Through a multi-layered solar energy absorption structure consisting of a black water-drying bag, a metal condensation plate, and a heat exchange plate, zero external energy consumption is achieved for boiler water preheating, fundamentally solving the high energy consumption problem. The black water-drying bag increases the absorption rate of solar radiation, directly converting sunlight into heat energy that is transferred to the water. Simultaneously, the metal condensation plate on the heat-conducting frame quickly absorbs solar energy and transfers it to the frame. Furthermore, the dual heat transfer path—with the water-drying bag attached to the frame and the heat exchange plate in contact with the water flow—further enhances heat utilization. The required heat is entirely generated by solar energy. Powered by solar energy, this technology requires no electricity or gas, saving on daily electricity costs compared to traditional electric heating and daily gas costs compared to gas heating. This results in reduced annual energy costs and directly improves feed mill profit margins. Traditional electric heating suffers from heat loss, while gas heating suffers from combustion loss and waste of flue gas heat. The solar energy absorption and heat transfer processes in this technology are all direct heat exchange processes without intermediate energy conversion steps, resulting in high heat utilization efficiency. Furthermore, it eliminates the need to pay high-load electricity surcharges or bear the risk of gas price fluctuations, ensuring long-term stable operating costs. This perfectly aligns with the feed industry's development trend of cost reduction, efficiency improvement, and green production. Attached Figure Description

[0025] The present application will be further described in detail below with reference to the accompanying drawings.
[0026] This application discloses a water preheating device for feed production. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4A water preheating device based on feed production includes a support 1, a heat exchanger 2, a water storage tank 3, and an insulation tank 4. The support 1 includes a support frame 11, and the heat exchanger 2 is arranged inside the support frame 11. The heat exchanger 2 includes a water drying bag 21, which has a long strip structure and is bent and laid flat inside the support frame 11.

A water pump 261 is connected to and fixed on the water inlet pipe 26, and the other end of the water inlet pipe 26 is connected to and assembled with the water storage tank 3. The water storage tank 3 is used to store boiler water. The other end of the water drying bag 21 is connected to and fixed with a drain pipe 27, which passes through the support frame 11. The end of the drain pipe 27 is connected to and assembled with the insulation tank 4, which is used to store preheated boiler water.
[0027] By adopting the above technical solution, the various components of the water preheating device work together to meet the rapid preheating requirements of feed production. The support frame 11 in support component 1 provides structural support, ensuring the stability and reliability of the entire device. The water-drying bag 21 in heat exchange component 2 has a long strip structure and is bent and laid flat inside the support frame 11, increasing the contact area with the outside air and improving heat exchange efficiency. The water inlet pipe 26 introduces boiler water from the water storage tank 3 into the water-drying bag 21, and the water flow is directionally driven by the water inlet pump 261. The drain pipe 27 discharges the preheated boiler water from the water-drying bag 21 and transports it to the insulation tank 4 to continuously provide a heat source for the next preheating. The water storage tank 3 stores and supplies sufficient boiler water to ensure continuous operation of the device. The insulation tank 4 maintains the water temperature through insulation measures, preventing the preheated water temperature from dropping too quickly, thus ensuring the preheating effect. Overall, this device rapidly increases the temperature of the feed water through an efficient heat exchange mechanism, meeting the temperature requirements for feed heating and improving production efficiency and feed quality.
[0028] Reference Figure 4Symmetrically vertically fixed support legs 12 are mounted on the bottom surface of the support frame 11, and multiple ground stakes 13 are installed through the bottom end of the support legs 12. The support frame 11 serves to support the entire device, and the symmetrically vertically fixed support legs 12 on its bottom surface increase the stability of the device and prevent it from tipping over due to uneven ground or external forces during use. The ground stakes 13 further reinforce the support legs 12, ensuring that the support frame 11 can be firmly fixed to the ground. An insulating cotton pad 14 is fixed to the inner wall of the support frame 11, and the insulating cotton pad 14 is used to keep the water bag 21 warm. The insulating cotton pad 14 is attached to the inner wall of the support frame 11, and its main function is to keep the water bag 21 warm, maintain the water temperature, and avoid the influence of changes in the external ambient temperature on the water temperature. Combining the functions of the above components, the support frame 11 provides stable support, the legs 12 and the ground nails 13 enhance stability, and the heat insulation pad 14 effectively maintains a constant water temperature inside the water bag 21, ensuring that the device can continuously provide a suitable heat source under different conditions.
[0029] Reference Figure 3 Multiple heat-conducting support frames 22 are fixed horizontally and vertically inside the support frame 11, and these support frames 22 are arranged in the bending gaps of the water-drying bag 21. The support frame 11 supports the entire device and has multiple heat-conducting support frames 22 fixed inside it. These heat-conducting support frames 22 are placed in the bending gaps of the water-drying bag 21 to improve heat transfer efficiency. Multiple metal sun-drying plates 23 are fixed on the top surface of the heat-conducting support frames 22, and multiple protruding strips are evenly fixed on the upper end surface of the multiple metal sun-drying plates 23. Multiple metal sun-drying plates 23 are fixed on each heat-conducting support frame 22. The upper end surface of these metal sun-drying plates 23 is enhanced with multiple protruding strips to increase the contact area with solar energy, thereby absorbing solar energy more effectively. Heat exchange plates 24 are arranged horizontally in the vertical direction between the multiple heat-conducting support frames 22 inside the support frame 11, and the two ends of the heat exchange plates 24 pass through the water-drying bag 21 and are fixed to the adjacent heat-conducting support frames 22. The heat exchange plate 24 is located between the heat-conducting support frames 22 and is fixed to the water-drying bag 21 and the heat-conducting support frames 22 at both ends. When solar radiation shines on the metal radiating plate 23, heat is transferred through the metal radiating plate 23 to the heat-conducting support frames 22, and then to the water in the water-drying bag 21. The interior of the heat-conducting support frame 22 is filled with heat-insulating cotton 25. The heat-insulating cotton 25 inside the heat-conducting support frame 22 can effectively reduce heat loss and improve the heat exchange efficiency.
[0030] Reference Figure 5The bottom of the insulated tank 4 is connected to a water supply pipe 42, and a valve 43 is installed on the water supply pipe 42. An insulating cotton sleeve 41 is fitted over the outer wall of the insulated tank 4. The bottom of the insulated tank 4 is connected to an external water source via the water supply pipe 42, and the valve 43 is installed on the water supply pipe 42 to control the water supply. The outer wall of the insulated tank 4 is wrapped with the insulating cotton sleeve 41 to maintain the temperature of the internal liquid. When water needs to be supplied to the insulated tank 4, external water is allowed to flow into the insulated tank 4 by opening the valve 43. The insulating cotton sleeve 41 effectively prevents the influence of the external ambient temperature on the internal liquid of the insulated tank 4, ensuring the temperature of the liquid inside the tank is stable and extending its insulation effect.
[0031] The implementation principle of a water preheating device for feed production according to an embodiment of this application is as follows: First, connect the water inlet pipe 26 at one end of the water-drying bag 21 to the water storage tank 3 and assemble it. Then connect the drain pipe 27 at the other end of the water-drying bag 21 to the heat preservation tank 4 and assemble it. When in use, start the water pump 261 on the water inlet pipe 26 to drive the boiler preheated water in the water storage tank 3 to flow from one end of the water-drying bag 21 to the other end of the water-drying bag 21. Then, sunlight shines on the black sun-drying bag 21. Black objects have a high absorption rate of sunlight, which can convert most of the solar radiation energy that shines on its surface into heat energy. The heat energy is transferred to the water flowing inside the sun-drying bag 21, heating the water in the sun-drying bag 21. At the same time, the metal sun-drying plate 23 on the heat-conducting support frame 22 is exposed to sunlight, and the heat is transferred to the heat-conducting support frame 22. Since the two sides of the heat-conducting support frame 22 are in close contact with the sun-drying bag 21, some of the heat is transferred into the water in the sun-drying bag 21. Then, the other part of the heat from the heat-conducting support frame 22 is transferred to the heat exchange plate 24. The water in the sun-drying bag 21 flows through the contact heat exchange plate 24, and the heat is transferred into the water in the sun-drying bag 21. Finally, the preheated water is transferred from the drain pipe 27 to the insulation tank 4 for storage. Later, the valve 43 on the water supply pipe 42 is opened to supply water to the boiler.
[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
