Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic aluminum profile pickling, and in particular to a self-made cooling system for a photovoltaic aluminum profile vertical oxidation pickling tank. Background Art

[0002] In modern industrial production, oxidation treatment of photovoltaic aluminum profiles is a key process. Pickling tanks are used to clean the surface of aluminum profiles and form oxide films. However, traditional pickling tanks have many deficiencies in cooling and temperature control, especially uneven temperature and local overheating, which often lead to reduced pickling efficiency and even affect the uniformity and quality of the oxide film.

[0003] Most of the pickling systems in the prior art use a single cooling method, which is difficult to flexibly adjust according to process requirements. For example, some systems use simple external cooling coils to reduce the temperature of the pickling solution, but when faced with complex process requirements, they are often unable to effectively adjust the temperature of each area, resulting in local temperatures that are too high or too low, thus affecting the pickling effect. In addition, the existing pickling liquid circulation and stirring systems are also insufficient in ensuring uniform flow of the liquid, and are prone to produce "cold zones" or "hot zones" with slow local flow rates or uneven temperatures, which further reduces the stability and efficiency of the treatment.

[0004] In this context, in order to improve the uniformity, cooling effect and temperature control accuracy of the pickling process, a new pickling tank cooling system that can effectively solve the uneven temperature and improve the processing stability is urgently needed. The system should have flexible cooling adjustment capabilities, be able to dynamically adjust the cooling intensity according to the temperature changes in the pickling tank, and be able to evenly stir the pickling liquid to ensure that the temperature and fluidity of the liquid remain balanced throughout the tank, so as to improve the pickling effect and processing efficiency. Summary of the invention

[0005] The present invention aims to solve the technical problems existing in the prior art or related art, such as uneven temperature control of pickling liquid and excessive temperature difference between pickling tank areas.

[0006] The system uses a number of technical solutions to achieve precise temperature control, balanced cooling and automatic adjustment of the liquid in the pickling tank, improving the stability and efficiency of the pickling process.

[0007] In a possible embodiment, the cooling system of the present invention includes a bath cooling pool and a pickling tank, the pickling tank is fixedly installed on the inner side of the bath cooling pool, and a refrigeration coil is spirally wound around the outer periphery of the pickling tank, and the coil is connected to a compression refrigeration component fixedly installed on the surface of the bath cooling pool to form a coolant circulation system. The surface of the pickling tank is evenly provided with laminar fins, which are interconnected through transverse flow channels and longitudinal flow channels to ensure uniform flow of the pickling liquid.

[0008] The present invention also includes a liquid guide box, which is installed on the surface of the pickling tank. The inside of the liquid guide box is driven by a driving motor to rotate a screw, and the screw is a double helical blade structure, and the spiral blades are in opposite directions and symmetrically distributed about the axis of the driving motor. This structure ensures that the liquid in the pickling tank is fully stirred, prevents local overcooling or overheating, and ensures uniform distribution of the pickling liquid.

[0009] In another possible implementation, the present invention adopts a multi-layer cooling channel design, and coolants of different temperatures flow through each layer of channels to form a temperature gradient, thereby improving the overall cooling effect and temperature uniformity. The cooling intensity of different areas can be adjusted according to actual needs through the independent start and stop control of the liquid guide box to ensure the balance of cooling and avoid overheating or overcooling of local areas.

[0010] The present invention further adopts an adaptive cooling system, which monitors the temperature of different areas in real time through an intelligent temperature sensor network arranged in the pickling tank, and automatically adjusts the flow rate, flow rate and stirring speed of the coolant according to feedback to maintain the dynamic cooling balance of the system and avoid excessive temperature difference and uneven temperature.

[0011] In addition, the present invention introduces pulsed coolant flow control technology, which uses intermittent high-voltage pulses to increase the flow rate of the coolant, improve the instantaneous cooling effect, and enhance the fluidity and turbulence intensity of the liquid, further improving the cooling efficiency and system stability, and avoiding the formation of cold and hot zones in the tank.

[0012] In another preferred embodiment, the system is equipped with a temperature control module and a liquid level monitoring and automatic filling system. The former adjusts the flow rate of the coolant and the power of the compression refrigeration component through a PID control algorithm to ensure that the temperature of the liquid in the pickling tank is always kept within the set range; the latter monitors the liquid levels of the pickling liquid and the coolant in real time through a liquid level sensor, and automatically adds liquid when the liquid level is lower than the preset value to ensure continuous and stable operation of the system.

[0013] In addition, the system also includes a dual-circulation cooling system. The primary cooling circulation system handles most of the heat in the pickling tank, while the secondary cooling circulation system performs fine adjustments for local areas, especially suitable for the edges of the pickling tank and hard-to-cool corners, to ensure overall cooling uniformity.

[0014] Through the above technical scheme, the present invention realizes the precise control of the temperature of each area in the pickling tank, avoids the problem of uneven treatment caused by excessive local temperature difference, greatly improves the stability and efficiency of the pickling process, and is suitable for various complex photovoltaic aluminum profile oxidation pickling process scenarios.

[0015] Beneficial effects of the present invention: 1. In the present invention, a stirring screw structure with double helical blades is adopted, and the screw is driven to rotate by a driving motor to evenly disperse the pickling liquid into the cross flow channel, so that the pickling liquid in various areas of the pickling tank surface is fully stirred, achieving a balanced distribution of liquid temperature, avoiding the phenomenon of local temperature being too high or too low, and ensuring the uniformity of the entire pickling process.

[0016] 2. In the present invention, a spirally wound refrigeration coil is arranged outside the pickling tank, and the refrigerant is circulated and cooled by a compression refrigeration component, so as to effectively reduce the temperature of the pickling liquid, avoid the problem of decreased treatment efficiency and uneven oxide film formation caused by overheating of the pickling liquid, and improve the stability of the pickling process and the treatment effect.

[0017] 3. In the present invention, multiple liquid guide box structures are arranged on the surface of the pickling tank to achieve segmented control of the longitudinal flow channel. Each liquid guide box can be started and stopped independently, so as to flexibly adjust the cooling intensity of each layer of the transverse flow channel. The system is dynamically adjusted according to the cooling needs of different areas, further improving the cooling balance and reducing the overheating or overcooling phenomenon in local areas.

[0018] 4. In the present invention, the pulsed coolant flow control technology is used to intermittently increase the coolant flow rate through high-voltage pulses to enhance the instantaneous cooling effect. This technology promotes the rapid flow of liquid, improves the turbulence intensity, enhances the heat exchange efficiency between the coolant and the tank wall, accelerates heat transfer, and maintains the coolant flow balance of the entire system, preventing the formation of cold and hot zones, and ensuring the stable operation of the system.

DETAILED DESCRIPTION

[0021] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0022] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0023] The following is combined with Figure 1-Figure 4 The invention describes a self-made cooling system for a photovoltaic aluminum profile vertical oxidation pickling tank provided in some embodiments of the present invention.

[0024] Embodiment 1:

[0025] In this embodiment, the cooling system mainly includes a bath cooling pool 100, a pickling tank 200, a refrigeration coil 140, a compression refrigeration component 130, a laminar fin plate 210, a liquid guide box 220, a stirring screw 230, a drive motor 221, an injection pump 120, a multi-layer cooling channel, an adaptive cooling system, a pulsed coolant flow control system, a temperature control module, and a liquid level monitoring and automatic filling system.

[0026] The pickling tank 200 is fixedly installed on the inner side of the cooling pool 100 . A refrigeration coil 140 is spirally wound around the outer circumference of the pickling tank. The refrigeration coil is cooled by a compression refrigeration assembly 130 .

[0027] The surface of the pickling tank 200 is evenly provided with laminar flow fins 210, which are interconnected through transverse flow channels and longitudinal flow channels 211. A plurality of liquid guide boxes 220 are also installed on the surface of the pickling tank, and a stirring screw 230 is arranged in the liquid guide box. The stirring screw is a double helical blade structure, and the blades on both sides are in opposite directions and symmetrically distributed along the axis of the driving motor 221.

[0028] When the driving motor 221 is started, it drives the stirring screw 230 to rotate, and evenly disperses the pickling liquid into the cross flow channel. Through the action of the spiral blades, the pickling liquid is fully stirred in each flow channel, ensuring the balanced distribution of the liquid temperature, avoiding the phenomenon of excessively high or low temperature in local areas, and ensuring the uniformity of the pickling process.

[0029] Specifically, the stirring screw with double helical blades allows the pickling liquid to flow evenly in the entire pickling tank 200, avoiding local overcooling or overheating, thereby improving the uniformity and processing efficiency of pickling.

[0030] In this embodiment, in order to further improve the cooling effect of the pickling tank 200, the system is designed with a multi-layer cooling channel structure. Coolants of different temperatures flow through each layer of cooling channels, and heat is transferred layer by layer through these coolants of different temperatures, thereby enhancing the overall cooling effect. Each cooling layer is controlled by a central controller, and the flow rate and flow of the coolant are independently adjusted according to the temperature requirements of different areas to ensure that each layer of coolant cools the pickling liquid evenly.

[0031] Specifically, the multi-layer cooling channel design enables the coolant to accurately control the temperature of each area, avoiding the situation where a single cooling layer is insufficient, ensuring the temperature uniformity of the liquid in the pickling tank, and improving the cooling efficiency.

[0032] In this embodiment, the adaptive cooling system monitors the temperature of different areas in real time through multiple temperature sensors arranged in the pickling tank 200 and the bath cooling pool 100. The temperature sensor transmits the temperature data to the central controller, and the central controller automatically adjusts the working state of the compression refrigeration component 130 and the injection pump 120 according to the feedback data. The adaptive cooling system is based on the PID control algorithm, and can adjust the flow rate of the coolant and the power of the compression refrigeration component according to actual needs to ensure that the temperature in the pickling tank is always kept within the set range.

[0033] Specifically, the adaptive cooling system can automatically adjust the cooling intensity according to the dynamic changes of the temperature in the tank to avoid overcooling or overheating, ensure the temperature balance of the pickling process, and improve the intelligence level and control accuracy of the system.

[0034] In this embodiment, in order to improve the fluidity and turbulence effect of the coolant, the system adopts pulsed coolant flow control technology. Through intermittent high-voltage pulses, the coolant is accelerated to flow in the form of pulses, increasing the contact area and flow velocity between the coolant and the pickling tank wall, thereby improving the instantaneous cooling effect.

[0035] Specifically, the pulsed coolant flow control system effectively improves the fluidity of the liquid, enhances the heat transfer between the coolant and the pickling tank wall, ensures that the coolant in the pickling tank flows evenly, and avoids the occurrence of cold and hot areas.

[0036] In this embodiment, the temperature control module of the system is composed of temperature sensors installed on the surface of the pickling tank 200 and the cooling pool 100. The temperature sensors detect the temperature changes of the pickling liquid and the cooling liquid in real time and transmit the temperature data to the central controller. The central controller adjusts the working state of the compression refrigeration component 130 and the injection pump 120 according to the set target temperature to ensure the constancy of the liquid temperature in the pickling tank.

[0037] Specifically, the temperature control module ensures that the temperature of the pickling solution is always maintained within the set range, avoiding overheating or overcooling, and improving the stability of the pickling process.

[0038] In this embodiment, the system is equipped with a liquid level monitoring system, and the liquid level sensors are installed in the pickling tank 200 and the cooling tank 100 to monitor the liquid level of the pickling liquid and the cooling liquid in real time. When the liquid level is lower than the preset value, the automatic filling system is started, and the filling pump 120 will replenish the required liquid from the liquid storage tank to ensure the continuous and stable operation of the system.

[0039] Specifically, the liquid level monitoring system and automatic filling function ensure the timely replenishment of pickling liquid and coolant, avoid affecting the treatment effect due to low liquid level, and improve the system's automation level and operating efficiency.

[0040] In this embodiment, the system also adopts a dual-circulation cooling design, including a primary circulation and a secondary circulation cooling system. The primary cooling circulation system processes most of the heat of the pickling liquid in the tank, and realizes a large-scale heat exchange through the refrigeration coil 140 and the compression refrigeration assembly 130. The secondary cooling circulation system is used to adjust the temperature of the local area, especially the edge and corner area of ​​the pickling tank. Through this dual-circulation design, the system can more accurately control the temperature of the whole and local areas.

[0041] Specifically, the double-circulation cooling system ensures the temperature uniformity of each area in the tank, avoids excessive temperature differences or local excessive temperatures, and improves the pickling effect.

[0042] Embodiment 2:

[0043] This embodiment further optimizes the multi-layer cooling channel design of the self-made cooling system of the photovoltaic aluminum profile vertical oxidation pickling tank, and combines the segmented control strategy to further improve the cooling efficiency and temperature balance of the system. This design introduces a segmented structure and an independent temperature control system in the cooling channel of the pickling tank to ensure that the cooling effect of each area can be adjusted independently to meet complex process requirements.

[0044] A plurality of cooling channels are designed outside the pickling tank 200. These channels are spirally wound around the periphery of the pickling tank and connected to the compression refrigeration assembly 130 through the refrigeration coil 140, forming a multi-layer cooling structure. Cooling liquids of different temperatures flow through each layer of cooling channels, thereby achieving layered cooling.

[0045] In order to further improve the cooling effect, the system divides the longitudinal channel 211 into sections by setting multiple liquid guide boxes 220 structures on the surface of the longitudinal channel 211. The cooling intensity of each cooling channel can be adjusted through independent start and stop control. The liquid guide box 220 is installed on the surface of the pickling tank, responsible for evenly guiding the pickling liquid or coolant into each layer of the cross channel, and controls the rotation of the screw 230 through the drive motor 221 to promote the uniform flow of the liquid.

[0046] By setting up independently controlled liquid guide boxes 220 in each cooling channel, the system can start and stop the coolant in each cooling channel in sections. Each liquid guide box 220 is managed by a central controller, and the coolant flow and flow rate can be adjusted in real time according to the temperature requirements of each layer, which can speed up the cooling speed of local areas and reduce the cooling intensity of certain areas.

[0047] This segmented control allows the flow of coolant in each layer of cross-flow channel to be adjusted independently. For example, for a higher temperature area, the cooling speed can be accelerated by increasing the operating frequency of the liquid guide box in that area; while for a lower temperature area, the operation of the liquid guide box can be slowed down or stopped to avoid overcooling.

[0048] In this embodiment, the coolant temperature in each layer of cooling channel can be controlled by an independent cooling circuit to form different temperature gradients. The coolant temperature in the outermost channel is relatively low and is used for initial cooling; while the coolant temperature in the inner layer gradually increases to ensure more uniform heat transfer between the inner and outer cooling channels. Through the interlayer temperature gradient design, heat is transferred layer by layer to avoid the occurrence of local overcooling or overheating.

[0049] The system is equipped with multiple temperature sensors distributed in various areas of the pickling tank. These sensors detect the temperature of each cooling channel in real time and transmit the data to the central controller. Based on the feedback information, the central controller automatically adjusts the start and stop status of each section of the liquid guide box 220 and the flow rate and flow of the coolant, thereby achieving precise adjustment of the cooling effect.

[0050] The temperature and flow rate of each cooling channel can be independently controlled according to the temperature requirements of different areas, ensuring that each layer of coolant can accurately cool the liquid in the pickling tank in different areas. Segmented control can better adapt to the temperature change requirements during the pickling process and effectively improve the overall cooling effect.

[0051] Applicable scenarios: This embodiment is suitable for production environments that require precise temperature control of different areas of the pickling tank. The design of multi-layer cooling channels and segmented control enables the system to flexibly adjust the cooling effect under different process conditions, and is suitable for complex processes with large temperature gradients inside the pickling tank and high temperature balance requirements.

[0052] Through the multi-layer cooling channel and segmented control design of this embodiment, the cooling effect of the photovoltaic aluminum profile vertical oxidation pickling tank has been significantly improved. The coolant temperature gradient in the multi-layer cooling channel and the independent start-stop control strategy enable the system to more flexibly adapt to the temperature requirements of different areas in the pickling tank, ensure temperature uniformity and cooling efficiency, and greatly improve the stability and overall performance of the pickling process.

[0053] Embodiment 3:

[0054] This embodiment provides a self-made cooling system for a photovoltaic aluminum profile vertical oxidation pickling tank based on a primary and secondary double-circulation cooling system, aiming to improve the cooling efficiency, especially to solve the problem of uneven temperature in the pickling tank through local adjustment, thereby ensuring the balance and stability of the temperature in the tank.

[0055] The cooling system includes a bath cooling pool 100, a pickling tank 200, a refrigeration coil 140, a compression refrigeration assembly 130, a laminar flow fin plate 210, a liquid guide box 220, a stirring screw 230, a drive motor 221, a liquid injection pump 120 and a temperature control module. The core design of the system is a primary and secondary double-circulation cooling system, which is used to handle the overall and local heat of the liquid in the pickling tank.

[0056] The main circulation cooling system processes most of the heat of the liquid in the tank, mainly acting on the cross flow channel and the longitudinal flow channel 211 of the pickling tank 200, and is responsible for the overall temperature regulation of the entire tank. The main circulation cooling system introduces the coolant into the bath cooling pool 100 through the injection pump 120. The coolant flows between the laminar fins 210, and the cross flow channel and the longitudinal flow channel 211 form a flow channel, which takes away most of the heat in the tank through the coolant.

[0057] When the temperature of the liquid in the pickling tank increases, the coolant flows on a large scale in the main circulation system, thereby ensuring that the liquid temperature of the entire tank body drops evenly. Since the main circulation cooling system covers most areas of the pickling tank, it effectively manages the overall heat and ensures the basic cooling needs of the system.

[0058] The secondary circulation cooling system is mainly composed of a refrigeration coil 140 and a compression refrigeration assembly 130. The refrigeration coil is spirally wound around the periphery of the pickling tank 200, and the compression refrigeration assembly realizes the secondary cooling function by circulating refrigerant. The main task of the secondary circulation system is to deal with the local temperature of the edge of the pickling tank or the corner area that is difficult to cool, especially the local hot spots that are difficult to quickly cover by the main circulation system.

[0059] The refrigerant circulates in the refrigeration coil through the compressed refrigeration component, taking away the heat from the outer wall of the pickling tank and local areas, ensuring that the temperature at the edge or hot spot of the pickling tank drops rapidly. By controlling the cooling effect of the refrigeration coil, the system can quickly adjust the local high-temperature area and effectively reduce the temperature unevenness.

[0060] When the primary and secondary dual-circulation cooling systems work together, the primary circulation system handles the main heat flow in the pickling tank, while the secondary circulation system focuses on the edge of the pickling tank or the local hard-to-cool area. This design can reduce the temperature over a large area while making fine adjustments to local temperature changes.

[0061] Implementation Effect

[0062] Through the design of the primary and secondary dual-circulation cooling system of this embodiment, the cooling efficiency of the photovoltaic aluminum profile vertical oxidation pickling tank has been significantly improved. The primary circulation system handles most of the heat in the pickling tank by covering a large range of coolant flow, while the secondary circulation system quickly responds to the temperature of the hot spot area through local regulation, ensuring that the entire system can accurately respond to local temperature changes while handling large-area heat. The coordinated use of the primary and secondary cooling systems effectively avoids the occurrence of uneven temperature in the tank, ensuring that the pickling process is more stable and efficient.

[0063] Embodiment 4:

[0064] This embodiment provides a self-made cooling system for a photovoltaic aluminum profile vertical oxidation pickling tank based on a pulsed coolant flow control technology. This technology increases the flow rate of the coolant by intermittently pulse-adjusting the speed of the drive motor 221, aiming to quickly improve the instantaneous cooling effect, while ensuring the balanced flow of the coolant to avoid the appearance of "cold areas" and "hot areas" in the tank.

[0065] The core components included in the system are similar to those in other embodiments, including a bath cooling pool 100, a pickling tank 200, a refrigeration coil 140, a compression refrigeration assembly 130, a laminar fin plate 210, a liquid guide box 220, a stirring screw 230 and a drive motor 221. In particular, in this embodiment, a pulsed coolant flow control technology is introduced to enhance the fluidity and instantaneous cooling effect of the system coolant. The system adjusts the speed of the drive motor 221 through a pulse current to intermittently increase the rotation speed of the stirring screw 230. Through this pulse regulation, the flow rate of the coolant is accelerated in a short time, the stirring effect is enhanced, and the liquid fluidity and turbulence intensity are significantly improved.

[0066] During normal operation, the drive motor maintains a constant speed to maintain the basic flow of the coolant. When the system detects that the temperature in certain areas rises rapidly or needs to be cooled instantly, the pulse current will intermittently increase the speed of the drive motor, and the stirring screw will rotate faster, thereby rapidly increasing the flow rate of the coolant. As the coolant flows faster, the heat exchange efficiency between the liquid in the tank and the tank wall and various areas is greatly improved.

[0067] Applicable scenarios: This pulsed coolant flow control technology is suitable for production environments that require rapid cooling, especially in situations where local temperatures may rise rapidly during the pickling process. By instantly accelerating the coolant flow rate, the system can effectively cope with temperature fluctuations and is suitable for efficient pickling and other processes that require precise temperature control. Through the pulsed coolant flow control technology of this embodiment, the cooling efficiency of the vertical oxidation pickling tank for photovoltaic aluminum profiles has been significantly improved. The system can adjust the speed of the drive motor through intermittent pulses to quickly accelerate the flow of the coolant, achieve strong cooling and enhance the turbulent effect. This technology can not only quickly reduce the temperature, but also effectively prevent the coolant from being retained in the tank, ensure the balanced flow of the liquid in the tank, avoid uneven temperature, and improve the stability and efficiency of the pickling process.
