Description

Technical Field

[0001] This utility model relates to the technical field of circulating water devices for acid production, and in particular to a circulating water device for acid production. Background Technology

[0002] The acid production process generates a significant amount of heat. A circulating water system continuously removes this hot water, cools it, and then returns it to the acid production system. This effectively lowers the temperature of the acid production equipment, ensuring the reaction occurs within a suitable temperature range. This not only improves the efficiency of the acid production reaction but also prevents damage from overheating, extending the equipment's lifespan.

[0003] For example, the utility model application with application number 202322463270.3 discloses a roasting acid production water circulation device, which uses a cooling liquefaction device to facilitate the cooling and liquefaction of a large amount of water vapor generated during the industrial acid production cooling process. This can reduce the generation of water vapor and thus reduce water consumption.

[0004] The above-mentioned applications still have shortcomings:

[0005] In this type of roasting acid production water circulation device, the cooling water is not filtered or cleaned of impurities during circulation. Moreover, the cooling water is more prone to scale precipitation at high temperatures. The precipitated scale adheres to the inner wall of the cooling pipes, especially the curved pipes, and is very difficult to clean. This not only affects the water flow rate but also the heat exchange efficiency. Furthermore, after heat exchange, the cooling water of this roasting acid production water circulation device enters the cooling tank and is only initially cooled by a fan, which can only perform initial cooling on the surface water, resulting in low cooling efficiency.

[0006] To address this issue, a circulating water device for acid production was designed. Utility Model Content

[0007] The main purpose of this invention is to provide a circulating water device for acid production that can agitate the circulating water inside the cooling cylinder, accelerate the flow of the circulating water and transfer heat to the heat dissipation fins more frequently. The increased flow rate also increases the convective heat transfer coefficient, thereby improving the heat transfer efficiency with the heat dissipation fins. Furthermore, the device filters and cleans the circulating water inside the cooling cylinder, reducing the accumulation of scale inside the cooling pipes and the resulting difficulty in cleaning, thus improving the cooling efficiency of the circulating water device for acid production.

[0008] The objective of this utility model can be achieved by adopting the following technical solution:

[0009] A circulating water device for acid production includes a housing, a motor mounted on the top of the housing, a rotating shaft fixed to the output shaft of the motor, and the bottom end of the rotating shaft extending through and into the interior of the housing. A cooling cylinder is mounted on the bottom of the housing. Stirring blades are evenly arranged on the bottom sidewall of the rotating shaft. A scraper is fixed to one end of the stirring blade and is slidably connected to the interior of the cooling cylinder. Heat dissipation fins are evenly arranged on the outer side of the cooling cylinder. An inlet pipe is installed on one side of the cooling cylinder. A filter layer is fixedly installed inside the cooling cylinder above the scraper. A liquid replenishment pipe is provided at the top of the inlet pipe. A cooling pipe is installed inside the housing, with the bottom end of the cooling pipe extending through and into the upper part of the filter layer. Heat dissipation fins are evenly fitted on the outer side of the cooling pipe. A pump body is mounted on the other end of the cooling pipe. Openings are evenly provided on the outer side of the housing. A linkage mechanism is provided between the rotating shaft and the housing.

[0010] Preferably, the linkage mechanism includes a sprocket and a fixed cylinder. The sprocket is set on the outside of the rotating shaft. The top of the outer shell is symmetrically installed on the fixed cylinder. Rotating rods are rotatably installed inside the fixed cylinders. Fan blades are evenly arranged on the outside of the rotating rods. A sprocket is fixed at the top of the rotating rods. A chain meshes between the sprocket and the sprocket.

[0011] Preferably, the outer side of the outer shell is uniformly provided with protective frames, and each protective frame is connected to the opening. The inside of each protective frame is equipped with a dustproof net.

[0012] Preferably, the diameter of sprocket one is larger than the diameter of sprocket two, and a protective coating is provided on the outer side of sprocket one.

[0013] Preferably, the cooling pipe is a spiral pipe, and the cooling pipe is installed on the inner side wall of the outer casing by clamps.

[0014] Preferably, a connection hole is provided at the connection between the filter layer and the rotating shaft, and a wear-resistant connecting pipe is provided inside the connection hole.

[0015] Preferably, the top and bottom of the fan blades are equipped with protective nets, and the connection between the fan blades and the rotating rod is equipped with a bearing.

[0016] The beneficial effects of this utility model are as follows:

[0017] This utility model provides a circulating water device for acid production. Through the coordinated use of a shell, motor, rotating shaft, stirring blade, scraper, pump body, cooling cylinder, cooling pipe, heat sink, filter layer, heat sink fins, inlet pipe and replenishment pipe, it can stir the circulating water inside the cooling cylinder, accelerate the flow of the circulating water to transfer heat to the heat sink fins more frequently, increase the flow rate, increase the convective heat transfer coefficient, improve the heat transfer efficiency with the heat sink fins, and filter and clean the circulating water inside the cooling cylinder, reducing the accumulation of scale inside the cooling pipe and the resulting difficulty in cleaning, thereby improving the cooling efficiency of the circulating water device for acid production.

[0018] By using sprocket one, fixed cylinder, rotating rod, fan blade, sprocket two, and chain in combination, the starting motor drives the rotating shaft to rotate, and the rotating shaft drives sprocket one to rotate. Sprocket one drives sprocket two and rotating rod to rotate through the chain, which quickly dissipates the heat outside the cooling pipe inside the shell, reduces the heat accumulation around the cooling pipe inside the shell, and improves the cooling efficiency of the circulating water. At the same time, the linkage between sprocket one and chain and sprocket two reduces the overall manufacturing cost, thereby improving the energy efficiency of the acid production circulating water device.

[0019] By using the vent, protective frame, and dustproof net in combination, outside air enters the interior of the casing for heat exchange. The dustproof net filters out impurities in the outside air, reducing the entry of impurities and dust and their adhesion to the outside of the heat sink, which affects the heat transfer and heat exchange efficiency of the heat sink, thereby improving the practicality of the acid production circulating water device.

[0025] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0026] like Figures 1-4As shown, this embodiment provides a circulating water device for acid production, including a housing 1. A motor 2 is installed on the top of the housing 1. A rotating shaft 3 is fixed to the output shaft of the motor 2, and the bottom end of the rotating shaft 3 extends through and into the interior of the housing 1. A cooling cylinder 7 is installed at the bottom of the housing 1. Stirring blades 4 are evenly arranged on the bottom side wall of the rotating shaft 3. A scraper 5 is fixed to one end of the stirring blades 4 and is slidably connected to the interior of the cooling cylinder 7. Heat dissipation fins 11 are evenly installed on the outer side of the cooling cylinder 7. An inlet pipe 12 is installed on one side of the cooling cylinder 7. A filter layer 10 is fixedly installed inside the cooling cylinder 7 and above the scraper 5. A connection hole is provided at the connection between the filter layer 10 and the rotating shaft 3, and a filter element is provided inside the connection hole. Wear-resistant connecting pipes reduce friction on filter layer 10 caused by the rotation of shaft 3. A replenishment pipe 13 is provided at the top of inlet pipe 12. When the circulating water volume is insufficient, external water can be introduced into inlet pipe 12 by opening the valve body on replenishment pipe 13 and enter cooling cylinder 7 through inlet pipe 12. Cooling pipe 8 is installed inside the outer shell 1, and the bottom end of cooling pipe 8 extends through and to the upper position of filter layer 10. Cooling pipe 8 is a spiral pipe and is installed on the inner side wall of outer shell 1 by clamp. Heat dissipation fins 9 are evenly sleeved on the outer side of cooling pipe 8. Pump body 6 is installed at the other end of cooling pipe 8. Openings 14 are evenly opened on the outer side of outer shell 1. Linkage mechanism 23 is provided between shaft 3 and outer shell 1.

[0027] Specifically, circulating water enters the cooling cylinder 7 through the inlet pipe 12. The motor 2 is started to drive the rotating shaft 3 to rotate. The rotating shaft 3 drives the stirring plate 4 and scraper 5 to rotate, stirring the circulating water. This causes the circulating water at different positions in the cooling cylinder 7 to come into contact with the heat dissipation fins 11. The heat dissipation fins 11 transfer the heat in the circulating water to the outside. The initially cooled circulating water passes through the filter layer 10 and enters the upper part of the filter layer 10, so that the impurities in the circulating water are blocked below the filter layer 10. The impurities adhering to the inner wall of the cooling cylinder 7 are scraped off by the rotation of the scraper 5. The drain valve at the bottom of the cooling cylinder 7 can be opened periodically to drain the sewage.

[0028] like Figures 1-3 As shown, the linkage mechanism 23 includes a first sprocket 15 and a fixed cylinder 16. The first sprocket 15 is sleeved on the outside of the rotating shaft 3. The top of the outer shell 1 is symmetrically installed on the fixed cylinder 16. Rotating rods 17 are rotatably installed inside the fixed cylinder 16. Fan blades 18 are evenly arranged on the outside of the rotating rods 17. Protective nets are provided at the top and bottom of the fan blades 18. Bearings are provided at the connection between the fan blades 18 and the rotating rods 17. The protective nets further play a dustproof role, reducing dust falling into the interior of the outer shell 1. A second sprocket 19 is fixed at the top of the rotating rods 17. The diameter of the first sprocket 15 is larger than the diameter of the second sprocket 19. The outer side of the first sprocket 15 is provided with a protective coating. The rotation speed of the smaller diameter second sprocket 19 is higher than that of the larger diameter first sprocket 15. One rotation of the first sprocket 15 can make the second sprocket 19 rotate several times. A chain 20 meshes between the second sprocket 19 and the first sprocket 15.

[0029] Specifically, when the motor 2 drives the shaft 3 to rotate, the shaft 3 drives the sprocket 15 to rotate. The sprocket 15 drives the sprocket 29 and the rotating rod 17 to rotate via the chain 20. The large-diameter sprocket 15 drives the small-diameter sprocket 29 to rotate, increasing the speed of the sprocket 29. This causes the sprocket 29 to drive the rotating rod 17 and the fan blade 18 to rotate rapidly, quickly dissipating the heat from the outside of the cooling pipe 8 inside the outer casing 1 and reducing the accumulation of heat inside the outer casing 1 and around the cooling pipe 8.

[0030] like Figure 1 and Figure 4 As shown, protective frames 21 are evenly arranged on the outer side of the outer shell 1, and the protective frames 21 are connected to the openings 14 respectively. Dustproof nets 22 are installed inside the protective frames 21.

[0031] Specifically, the rotation of the lever 17 and the fan blade 18 draws the air out of the housing 1. Under the action of the opening 14, the outside air continuously enters the interior of the housing 1. Under the action of the dust filter 22, impurities in the outside air are filtered, reducing the entry of impurities and dust and their adhesion to the outside of the heat sink 9.

[0032] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
