Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and in particular to a high-efficiency and energy-saving stainless steel pipe refrigerated dryer. Background Technology

[0002] With the increasing demand for stainless steel pipe processing in industrial production, traditional refrigerated dryers suffer from problems such as low energy efficiency, cumbersome operation, and short service life. To improve production efficiency and reduce energy consumption, developing a high-efficiency and energy-saving refrigerated dryer has become an urgent technical challenge. This type of refrigerated dryer significantly improves the refrigeration effect by optimizing the cooling cycle, improving heat exchange efficiency, and intelligent control, while reducing energy waste and adapting to the high-intensity working requirements of stainless steel pipe processing.

[0003] However, in actual use, the following shortcomings still exist. For example, existing stainless steel tube refrigerated dryers cannot achieve heat recovery and reuse to improve the overall energy efficiency of the refrigerated dryer. During the refrigeration process, the refrigerated dryer releases a large amount of high-temperature heat through the condenser. If it is directly discharged into the environment, it will cause heat energy waste. If this heat is recovered and reused, it can significantly improve the overall energy efficiency of the system. Refrigerated dryers are major power consumers, especially when running under high load or continuously. If the cooling demand cannot be reduced through heat recovery, the equipment will need to rely on more electricity to compensate for energy loss, resulting in increased electricity expenses.

[0004] Therefore, this utility model proposes a high-efficiency and energy-saving stainless steel tube refrigerated dryer to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and propose a high-efficiency and energy-saving stainless steel tube refrigerated dryer.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a high-efficiency and energy-saving stainless steel tube refrigerated dryer, including a housing, and further comprising:

[0007] A cold drying assembly includes a steel pipe inlet on one side of the housing, a fan installed on the side of the housing near the steel pipe inlet, a heat-conducting plate fixed inside the housing near the bottom, and heat dissipation fins provided at the bottom of the heat-conducting plate.

[0008] A heat recovery assembly includes a tank fixed to one side of a housing, an air inlet on the tank, a connecting pipe on the air inlet, the other end of the connecting pipe on the housing, a second air outlet on the side of the tank away from the air inlet, a guide pipe fixed inside the tank, fins fixed on the guide pipe, a spiral guide plate fixed inside the housing, and heat dissipation fins on the guide pipe.

[0009] Furthermore, an air guide plate is fixed inside the box.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the air guide plate inside the box is mainly used to guide the air flow. When the fan is running and blows air into the box, the air guide plate will change the direction of the air flow, so that the air can be more evenly distributed inside the box. This can ensure that the air is in full contact with the steel pipe to be dried, improve the drying efficiency, and avoid local air flow obstruction affecting the drying effect.

[0011] Furthermore, a first air outlet is provided on the side of the housing away from the fan.

[0012] The beneficial effect of adopting the above-mentioned further solution is that after the fan blows air into the box, the hot air generated in the box needs to be discharged from the box. The first air outlet is set on the side away from the fan, which allows the air to have enough flow path and time for heat exchange in the box, and then be discharged from the first air outlet, maintaining the normal circulation of air in the box.

[0013] Furthermore, the other end of the connecting pipe is fixed to the side of the housing near the first air outlet.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the connecting pipe is used to introduce the hot air inside the box into the tank of the heat recovery component, and its other end is fixed on the side near the first air outlet. This ensures that the hot air introduced into the tank has a high heat value, which is convenient for subsequent heat recovery and utilization.

[0015] Furthermore, a liquid inlet is provided on the side of the tank away from the air inlet, and a liquid outlet is provided on the bottom of the tank near the liquid inlet.

[0016] The beneficial effects of adopting the above-mentioned further scheme are: the liquid inlet is used to inject liquid for heat exchange into the guide tube. After the liquid enters from the liquid inlet, it exchanges heat with the heat source in the tank and its temperature rises after absorbing heat. The liquid outlet discharges the heated liquid out of the tank, realizing the circulation of the liquid and ensuring the continuous heat exchange.

[0017] Furthermore, one end of the guide tube is located at the inlet, and the other end of the guide tube is located at the outlet.

[0018] The beneficial effects of adopting the above-mentioned further scheme are: the guide pipe plays the role of guiding the flow of liquid. The external liquid enters the guide pipe from the liquid inlet and exchanges heat with the heat source in the tank during the flow process in the guide pipe. Since there are fins on the guide pipe, the heat exchange area can be increased and the heat exchange efficiency can be improved. Finally, the liquid that has absorbed heat is discharged from the liquid outlet.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, the stainless steel pipe to be processed enters the chamber through the steel pipe inlet. The fan starts, accelerating the airflow to ensure full contact between the air and the steel pipe, and removes the heat inside the chamber, achieving initial cold drying. The heat-conducting plate absorbs the heat generated inside the chamber and releases it through the bottom heat dissipation fins. At the same time, the heat recovery component works, and the connecting pipe introduces the hot air carrying heat from inside the chamber into the tank through the air inlet. The external low-temperature liquid is introduced into the tank through the guide pipe. The fins on the guide pipe significantly increase the heat exchange area. The spiral guide plate inside the chamber guides the hot air to flow in an orderly manner, causing the hot air to spiral around the guide pipe. With the help of the heat dissipation fins, the heat is fully exchanged with the low-temperature liquid inside the guide pipe. After the heat from the hot air is transferred to the liquid, it is discharged through the second air outlet. The low-temperature liquid absorbs heat, heats up, and flows out, realizing heat recovery and reuse, and improving the overall energy efficiency of the refrigerated dryer.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1-4 As shown, this embodiment provides a technical solution: a high-efficiency and energy-saving stainless steel tube refrigerated dryer, including a housing 1, and further comprising:

[0031] The cold drying assembly 2 includes a steel pipe inlet 21 opened on one side of the box 1, a fan 22 installed on the side of the box 1 near the steel pipe inlet 21, and a heat-conducting plate 25 fixed inside the box 1 near the bottom. Heat dissipation fins 26 are provided at the bottom of the heat-conducting plate 25.

[0032] The heat recovery assembly 3 includes a tank 31 fixed to one side of the housing 1, an air inlet 34 on the tank 31, a connecting pipe 32 on the air inlet 34, the other end of the connecting pipe 32 being attached to the housing 1, a second air outlet 33 on the side of the tank 31 away from the air inlet 34, a guide pipe 37 fixed inside the tank 31, fins 38 fixed on the guide pipe 37, a spiral guide plate 39 fixed inside the housing 1, and heat dissipation fins 26 mounted on the guide pipe 37. The stainless steel pipe to be processed enters the housing 1 through the steel pipe inlet 21. The fan 22 is started to accelerate airflow, ensuring full contact between the air and the steel pipe and carrying away the heat inside the housing 1, achieving preliminary cooling and drying. The heat-conducting plate 25 absorbs the heat. The heat generated inside the housing 1 is released through the bottom heat dissipation fins 26. At the same time, the heat recovery component 3 works. The connecting pipe 32 introduces the hot air carrying heat from the housing 1 into the tank 31 through the air inlet 34. The external low-temperature liquid is introduced into the tank 31 through the guide pipe 37. The fins 38 on the guide pipe 37 greatly increase the heat exchange area. The spiral guide plate 39 inside the housing 1 guides the hot air to flow in an orderly manner, so that the hot air flows spirally around the guide pipe 37. With the help of the heat dissipation fins 26, the heat is fully exchanged with the low-temperature liquid inside the guide pipe 37. After the heat of the hot air is transferred to the liquid, it is discharged through the second air outlet 33. The low-temperature liquid absorbs heat, rises in temperature and flows out, realizing heat recovery and reuse, and improving the overall energy efficiency of the refrigerated dryer.

[0033] The above solutions also have the problem that, when the stainless steel pipes are being cold-dried, continuous heat exchange cannot be guaranteed. Figure 3As shown: A guide plate 23 is fixed inside the box 1. The guide plate 23 inside the box 1 is mainly used to guide the air flow. When the fan 22 is running, it blows air into the box 1. The guide plate 23 will change the direction of the air flow, so that the air can be more evenly distributed inside the box 1. This can ensure that the air is in full contact with the steel pipe to be dried, improve the drying efficiency, and avoid local air flow obstruction affecting the drying effect. A first air outlet 24 is set on the side of the box 1 away from the fan 22. After the fan 22 blows air into the box 1, the hot air generated in the box 1 needs to be discharged from the box 1. The first air outlet 24 is set on the side away from the fan 22, so that the air has enough flow path and time to exchange heat in the box 1, and then is discharged from the first air outlet 24, maintaining the normal circulation of air in the box 1.

[0034] like Figures 1-2 as well as Figure 4 As shown, the other end of the connecting pipe 32 is fixed to the side of the housing 1 near the first air outlet 24. The connecting pipe 32 is used to introduce hot air from the housing 1 into the tank 31 of the heat recovery assembly 3. The other end of the pipe is fixed to the side near the first air outlet 24, which ensures that the hot air introduced into the tank 31 has a high heat value, facilitating subsequent heat recovery and utilization. A liquid inlet 35 is provided on the side of the tank 31 away from the air inlet 34, and a liquid outlet 36 is provided on the bottom of the tank 31 near the liquid inlet 35. The liquid inlet 35 is used to inject liquid for heat exchange into the guide pipe 37. After the liquid enters from the liquid inlet 35, it flows into the tank 31. The liquid exchanges heat with the heat source, and its temperature rises after absorbing heat. The outlet 36 then discharges the heated liquid from the tank 31, realizing the circulation of the liquid and ensuring continuous heat exchange. One end of the guide pipe 37 is set on the inlet 35, and the other end of the guide pipe 37 is set on the outlet 36. The guide pipe 37 guides the flow of liquid. The external liquid enters the guide pipe 37 from the inlet 35 and exchanges heat with the heat source in the tank 31 during the flow of the guide pipe 37. Since there are fins 38 on the guide pipe 37, the heat exchange area can be increased and the heat exchange efficiency can be improved. Finally, the liquid that has absorbed heat is discharged from the outlet 36.

[0035] Working principle:

[0036] like Figures 1-4As shown, the stainless steel pipe to be processed enters the chamber 1 through the steel pipe inlet 21 on one side. At this time, the fan 22 installed near the steel pipe inlet 21 is started to accelerate the airflow, allowing the air to fully contact the steel pipe and remove the heat inside the chamber 1, achieving preliminary cold drying. Inside the chamber 1, a heat-conducting plate 25 is fixed near the bottom. It can absorb the heat generated inside the chamber 1 and release the heat through the heat dissipation fins 26 at the bottom. At the same time, an air guide plate 23 is also fixed inside the chamber 1. When the fan 22 blows air into the chamber... After the airflow is reduced to that of the casing 1, the air guide plate 23 changes the airflow direction, ensuring that the air is evenly distributed inside the casing 1. This ensures that the air is in full contact with the steel pipe, improving the cooling and drying efficiency and preventing localized poor airflow from affecting the cooling and drying effect. After heat exchange, the heated air is discharged from the first air outlet 24 on the side of the casing 1 away from the fan 22. This allows the air to have sufficient flow path and time for heat exchange within the casing 1, thus maintaining normal air circulation within the casing 1. In terms of heat recovery, the heat recovery component 3 plays a key role, and the connecting pipe 32... One end of the tube is fixed to the side of the housing 1 near the first air outlet 24. It fully absorbs the hot air with a high temperature and introduces it into the tank 31 through the air inlet 34. The tank 31 has a liquid inlet 35 on the side away from the air inlet 34 and a liquid outlet 36 on the bottom side near the liquid inlet 35. The two ends of the guide tube 37 are connected to the liquid inlet 35 and the liquid outlet 36, respectively. The external low temperature liquid enters the guide tube 37 from the liquid inlet 35 and exchanges heat with the hot air in the tank 31 during the flow process in the guide tube 37. The fins 38 fixed on the guide tube 37 significantly increase the heat exchange area and improve the heat exchange efficiency. In addition, the spiral guide plate 39 inside the housing 1 guides the hot air to flow in an orderly manner, making it spiral around the guide tube 37. Together with the heat dissipation fins 26, the heat of the hot air is fully transferred to the low-temperature liquid inside the guide tube 37. After the heat of the hot air is transferred to the liquid, it is discharged through the second air outlet 33. The low-temperature liquid absorbs heat and is heated up before being discharged from the liquid outlet 36, realizing the recovery and reuse of heat and greatly improving the overall energy efficiency of the refrigerated dryer.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
