Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pickling of photovoltaic aluminum profiles, in particular to a self-made cooling system for a vertical oxidation pickling tank of photovoltaic aluminum profiles. BACKGROUND

[0002] In modern industrial production, the oxidation treatment of photovoltaic aluminum profiles is a key process. The pickling tank is used to clean the surface of the aluminum profile and form an oxidation film. However, the traditional pickling tank has many shortcomings in cooling and temperature control, especially uneven temperature and local overheating, which often leads to reduced pickling efficiency and even affects the uniformity and quality of the oxidation film.

[0003] Most of the pickling systems in the prior art use a single cooling method, which is difficult to adjust flexibly 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 often cannot effectively adjust the temperature of each region, resulting in local temperature being too high or too low, which affects the pickling effect. In addition, the existing pickling solution circulation and stirring system also has shortcomings in ensuring uniform liquid flow, which can easily produce "cold zones" or "hot zones" with slow local flow or uneven temperature, which further reduces the stability and efficiency of the process.

[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 is needed that can effectively solve the problem of uneven temperature and improve the stability of the process. The system should have flexible cooling adjustment capability, be able to dynamically adjust the cooling intensity according to the temperature changes in the pickling tank, and be able to uniformly stir the cooling liquid to ensure that the temperature and flow of the liquid remain balanced throughout the tank to improve the pickling effect and processing efficiency. SUMMARY

[0005] The present application aims to solve the technical problems of uneven temperature control of pickling solution, large temperature difference between regions of pickling tank, etc. in the prior art or related art.

[0006] The system realizes precise temperature control, balanced cooling and automatic adjustment of the liquid in the pickling tank through multiple technical solutions, improving the stability and efficiency of the pickling process.

[0007] In one possible implementation, the cooling system of the present application 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. The coil is in communication with a compression refrigeration assembly fixedly installed on the surface of the bath cooling pool, forming a coolant circulation system. The surface of the pickling tank is uniformly provided with laminar flow fins, which are in communication with each other through cross-flow channels and longitudinal flow channels, for ensuring uniform flow of the cooling liquid.

[0008] The application also comprises a liquid guide box which is installed on the surface of the pickling tank, the interior of the liquid guide box is driven by a driving motor to rotate a screw rod, the screw rod is a double helical blade structure, the helical blades are opposite in direction and are symmetrically distributed about the axis of the driving motor. The structure ensures sufficient agitation of the liquid in the pickling tank, prevents local overcooling or overheating, and ensures uniform distribution of the cooling liquid.

[0009] In another possible implementation, the application is designed by multiple layers of cooling channels, different temperatures of cooling liquid flow in each layer of channel, forming a temperature gradient, and further improving the overall cooling effect and temperature uniformity. The cooling intensity of different areas can be adjusted according to actual needs through independent start-stop control of the liquid guide box, ensuring the balance of cooling and avoiding overheating or overcooling in local areas.

[0010] The application further adopts an adaptive cooling system, which monitors the temperature of different areas in real time through a network of intelligent temperature sensors arranged in the pickling tank, and automatically adjusts the flow rate, flow and stirring speed of the cooling liquid according to the feedback, maintains the dynamic cooling balance of the system, and avoids the occurrence of large temperature difference and temperature unevenness.

[0011] In addition, the application introduces pulse cooling liquid flow control technology, which uses intermittent high pressure pulse to increase the flow rate of the cooling liquid, improve the instantaneous cooling effect, and enhance the flowability and turbulence intensity of the liquid, further improving the cooling efficiency and stability of the system, 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 of the cooling liquid and the power of the compressed refrigeration component through a PID control algorithm, ensuring that the temperature of the liquid in the pickling tank always remains within the set range. The latter monitors the liquid level of the pickling liquid in real time through a liquid level sensor and automatically fills the liquid when the liquid level is below the preset value, ensuring continuous and stable operation of the system.

[0013] In addition, the system also comprises a double-circulation cooling system, the main cooling circulation system handles most of the heat in the pickling tank, and the secondary cooling circulation system finely adjusts the local area, especially suitable for the edges and corners of the pickling tank which are difficult to cool, ensuring the uniformity of the overall cooling.

[0014] Through the above technical solutions, the application realizes accurate 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 scenes.

[0015] The beneficial effects of the application are:

[0016] 1. The present application adopts a stirring screw structure with double helical blades, and rotates the screw through a driving motor to uniformly disperse the cooling liquid into the cross-flow channel, thereby fully stirring the cooling liquid in each area of the pickling tank surface, achieving balanced distribution of liquid temperature and avoiding local over-high or over-low temperature, ensuring uniformity of the entire pickling process.

[0017] 2. In the present application, a spiral-wound refrigeration coil is arranged outside the pickling tank, and the refrigerant is circulated and cooled by a compression refrigeration assembly, effectively reducing the temperature of the pickling liquid, avoiding the problems of decreased processing efficiency and uneven formation of oxide film caused by overheating of the pickling liquid, and improving the stability and processing effect of the pickling process.

[0018] 3. In the present application, a plurality of 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 independently started and stopped, thereby flexibly adjusting the cooling intensity of each layer of cross-flow channel. The system dynamically adjusts according to the cooling needs of different areas, further improving the cooling balance and reducing the overheating or overcooling phenomenon in local areas.

[0019] 4. In the present application, through the pulse cooling liquid flow control technology, the cooling liquid flow rate is increased by high-pressure pulse intermittently, enhancing the instantaneous cooling effect. This technology promotes the rapid flow of liquid, improves the turbulence intensity, enhances the heat exchange efficiency between the cooling liquid and the tank wall, accelerates the heat transfer, and maintains the balance of the overall system cooling liquid flow, preventing the formation of cold and hot zones, ensuring stable operation of the system.

DETAILED DESCRIPTION

[0026] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the specific embodiments and drawings. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0027] It is understood that the above description is only exemplary and is not intended to limit the scope of the present application.

[0028] The specific embodiments of the present application will be further described below with reference to the accompanying drawings. Figures 1-4 The cooling system of the vertical oxidation and pickling tank for the photovoltaic aluminum profile provided by some embodiments of the present application is described.

[0029] In this embodiment, the cooling system mainly comprises a bath cooling pool 100, a pickling tank 200, a refrigeration coil 140, a compression refrigeration assembly 130, laminar flow fins 210, liquid guide boxes 220, stirring screws 230, a driving motor 221, a liquid injection pump 120, multi-layer cooling channels, a self-adaptive cooling system, a pulse cooling liquid flow control system, a temperature control module, and a liquid level monitoring and automatic filling system.

[0030] The pickling tank 200 is fixedly installed on the inner side of the bath cooling pool 100, and the refrigeration coil 140 is spirally wound around the outer periphery of the pickling tank. The refrigeration coil is cooled by the compression refrigeration assembly 130.

[0031] The laminar flow fins 210 are uniformly arranged on the surface of the pickling tank 200, and the fins are connected to each other through cross-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 the liquid guide boxes are provided with stirring screws 230. The stirring screws are double helical blade structures, the blade directions of the two sides are opposite, and the two sides are symmetrically distributed along the axis of the driving motor 221.

[0032] When the driving motor 221 is started, the stirring screws 230 are driven to rotate, and the cooling liquid is uniformly dispersed into the cross-flow channels. Through the action of the helical blades, the cooling liquid is fully stirred in each flow channel, ensuring the uniform distribution of the liquid temperature and avoiding the phenomenon of excessively high or low temperature in local areas, thereby ensuring the uniformity of the pickling process.

[0033] Specifically, the stirring screws with double helical blades uniformly flow the cooling liquid around the entire pickling tank 200, avoiding the phenomenon of local overcooling or overheating, and improving the uniformity and processing efficiency of the pickling.

[0034] 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. Different temperature cooling liquids flow in each cooling layer, and heat is transferred layer by layer through these cooling liquids 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 cooling liquid are independently adjusted according to the temperature requirements of different areas, thereby ensuring the uniform cooling of the cooling liquid on the pickling liquid.

[0035] Specifically, the multi-layer cooling channel design enables precise temperature control of each region, avoiding the insufficient effect of a single cooling layer, ensuring the temperature uniformity of the liquid in the pickling tank, and improving the cooling efficiency.

[0036] In this embodiment, the adaptive cooling system monitors the temperature of different regions in real time through multiple temperature sensors arranged in the pickling tank 200 and the bath cooling pool 100. The temperature sensors transmit temperature data to the central controller, which automatically adjusts the working state of the compressed refrigeration assembly 130 and the liquid injection pump 120 based on the feedback data. The adaptive cooling system can adjust the flow of the cooling liquid and the power of the compressed refrigeration assembly based on the PID control algorithm to ensure that the temperature in the pickling tank always remains within the set range.

[0037] Specifically, the adaptive cooling system can automatically adjust the cooling intensity according to the dynamic changes of the temperature in the tank, avoiding overcooling or overheating, ensuring the temperature uniformity of the pickling process, and improving the intelligent level and control accuracy of the system.

[0038] In this embodiment, in order to improve the flowability and turbulence effect of the cooling liquid, the system adopts a pulse type cooling liquid flow control technology. Through intermittent high-pressure pulses, the cooling liquid flows in a pulse form, increasing the contact area and flow speed between the cooling liquid and the pickling tank wall, thereby improving the instantaneous cooling effect.

[0039] Specifically, the pulse type cooling liquid flow control system effectively improves the flowability of the liquid, enhances the heat transfer between the cooling liquid and the pickling tank wall, ensures the uniform flow of the cooling liquid in the pickling tank, and avoids the occurrence of cold and hot zones.

[0040] 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 bath 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 compressed refrigeration assembly 130 and the liquid injection pump 120 according to the set target temperature to ensure the constancy of the liquid temperature in the pickling tank.

[0041] Specifically, the temperature control module ensures that the temperature of the pickling liquid always remains within the set range, avoiding overheating or overcooling, and improving the stability of the pickling process.

[0042] In this embodiment, the system is equipped with a liquid level monitoring system, and the liquid level sensor is installed in the pickling tank 200 and the bath cooling pool 100 to monitor the liquid level of the cooling liquid in real time. When the liquid level is lower than the preset value, the automatic filling system starts, and the liquid injection pump 120 supplements the required liquid from the liquid storage tank to ensure the continuous and stable operation of the system.

[0043] Specifically, the liquid level monitoring system and automatic filling function ensure timely replenishment of pickling liquid, avoid the impact on treatment effect due to low liquid level, and improve the automation level and operation efficiency of the system.

[0044] In this embodiment, the system also adopts a double-circulation cooling design, including a main circulation and a secondary circulation cooling system. The main cooling circulation system handles most of the heat of the cooling liquid outside the pickling tank 200, and achieves 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 local areas, especially the edge and corner areas of the pickling tank. Through this double-circulation design, the system can more accurately control the temperature of the overall and local areas.

[0045] Specifically, the double-circulation cooling system ensures the temperature uniformity of each area in the tank, avoids the phenomenon of excessive temperature difference or local high temperature, and improves the pickling effect.

[0046] Embodiment 2: This embodiment further optimizes the multi-layer cooling channel design of the self-made cooling system of the vertical oxidation and pickling tank for photovoltaic aluminum profiles, and combines with the segmented control strategy, further improves the cooling efficiency and temperature uniformity of the system. This design introduces a segmented structure and an independent temperature control system on the cooling channel of the pickling tank, ensuring that the cooling effect of each area can be independently adjusted to adapt to complex process requirements.

[0047] Outside the pickling tank 200, multiple cooling channels are designed, which are connected in a spiral manner around the outer periphery of the pickling tank, connected to the compression refrigeration assembly 130 through the refrigeration coil 140, forming a multi-layer cooling structure. Different temperatures of cooling liquid flow in each layer of cooling channel, so as to realize layered cooling.

[0048] In order to further improve the cooling effect, the system divides the longitudinal flow channel 211 into segments by setting multiple liquid guide boxes 220 on the surface of the longitudinal flow channel 211, and the cooling intensity of each segment of the cooling channel can be adjusted by independent start-stop control. The liquid guide box 220 is installed on the surface of the pickling tank, responsible for uniformly guiding the cooling liquid into each layer of horizontal flow channel, and controls the rotation of the screw rod 230 through the driving motor 221 to promote the uniform flow of the liquid.

[0049] By setting the independently controlled liquid guide box 220 in each segment of the cooling channel, the system can segmentally start and stop control the cooling liquid of each layer of cooling channel. Each liquid guide box 220 is managed by the central controller, and the adjustment of the cooling liquid flow and flow rate can be adjusted in real time according to the temperature demand of each layer, which can speed up the cooling speed of local area, or slow down the cooling intensity of certain area.

[0050] This segmented control allows the flow of cooling liquid in each layer's cross-flow channel to be independently adjusted. For example, for areas with higher temperatures, the cooling speed can be increased by increasing the operating frequency of the liquid guide box in that area; for areas with lower temperatures, the operation of the liquid guide box can be slowed down or stopped to avoid overcooling.

[0051] In this embodiment, the cooling liquid temperature in each layer's cooling channel can be controlled by independent cooling circuits, forming different temperature gradients. The cooling liquid temperature in the outermost layer channel is lower, used for preliminary cooling; while the cooling liquid temperature in the inner layers gradually increases, ensuring more uniform heat transfer between the inner and outer cooling channels. Through the design of interlayer temperature gradient, heat is transferred layer by layer, avoiding the occurrence of local overcooling or overheating.

[0052] 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. The central controller automatically adjusts the start-stop state of each segment of the liquid guide box 220 and the flow rate and flow of the cooling liquid according to the feedback information, thereby achieving precise adjustment of the cooling effect.

[0053] 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 cooling liquid can precisely cool the liquid in the pickling tank in different areas. The segmented control can better adapt to the temperature change requirements during pickling, effectively improving the overall cooling effect.

[0054] Applicable scenarios:

[0055] This embodiment is suitable for production environments that require precise temperature control of different areas of the pickling tank. The design of multiple cooling channels and segmented control allows the system to flexibly adjust the cooling effect under different process conditions, suitable for complex processes with large temperature gradients and high temperature uniformity requirements inside the pickling tank.

[0056] Through the design of multiple cooling channels and segmented control in this embodiment, the cooling effect of the photovoltaic aluminum profile vertical oxidation pickling tank has been significantly improved. The temperature gradient of the cooling liquid in the multiple cooling channels and the independent start-stop control strategy allow the system to more flexibly adapt to the temperature requirements of different areas inside the pickling tank, ensuring temperature uniformity and cooling efficiency, greatly improving the stability and overall performance of the pickling process.

[0057] Embodiment 3: This embodiment provides a photovoltaic aluminum profile vertical oxidation pickling tank self-made cooling system based on a primary and secondary double-circulation cooling system, aiming to improve the cooling efficiency, especially to solve the problem of uneven temperature inside the pickling tank through local adjustment, ensuring the uniformity and stability of the temperature inside the tank.

[0058] The cooling system includes a bath cooling pool 100, an acid washing 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.

[0059] The main circulation cooling system handles most of the heat in the tank, mainly acting on the cross-flow channel and longitudinal flow channel 211 of the acid washing tank 200, and is responsible for the overall temperature regulation of the tank. The main circulation cooling system introduces cooling liquid into the bath cooling pool 100 through the liquid injection pump 120, and the cooling liquid flows between the laminar flow fin plates 210. The cross-flow channel and longitudinal flow channel 211 form a flow channel, and most of the heat in the tank is taken away by the cooling liquid.

[0060] When the temperature of the liquid in the acid washing tank rises, the cooling liquid flows in the main circulation system on a large scale, thereby ensuring that the temperature of the liquid in the entire tank body drops uniformly. Since the main circulation cooling system covers most of the area of the acid washing tank, it effectively manages the overall heat and ensures the basic cooling needs of the system.

[0061] The secondary circulation cooling system mainly consists of a refrigeration coil 140 and a compression refrigeration assembly 130. The refrigeration coil is spirally wound around the outer periphery of the acid washing 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 handle the local temperature of the edge or corner area of the acid washing tank that is difficult to cool, especially the local hot spots that are difficult for the main circulation system to quickly cover.

[0062] The refrigerant circulates in the refrigeration coil through the compression refrigeration assembly, taking away the heat of the outer wall of the acid washing tank and the local area, ensuring that the temperature of the edge or hot spot area of the acid washing tank drops rapidly. By controlling the refrigeration effect of the refrigeration coil, the system can quickly adjust the local high-temperature area and effectively reduce temperature unevenness.

[0063] When the main and secondary circulation cooling systems work together, the main circulation system handles the main heat flow in the acid washing tank, while the secondary circulation system focuses on the edge or local difficult-to-cool areas of the acid washing tank. This design can simultaneously cool a large area and finely adjust the local temperature changes.

[0064] Implementation effect: Through the design of the primary and secondary double-circulation cooling system in this embodiment, the cooling efficiency of the vertical oxidation and pickling tank for photovoltaic aluminum profiles has been significantly improved. The primary circulation system handles most of the heat in the pickling tank by covering a large range of cooling liquid flow, while the secondary circulation system quickly responds to the temperature of the hot spot area through local adjustment, ensuring that the entire system can accurately respond to local temperature changes while handling large-area heat. The 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.

[0065] Example 4: This embodiment provides a self-made cooling system for a vertical oxidation and pickling tank for photovoltaic aluminum profiles based on pulse cooling liquid flow control technology. This technology increases the flow rate of the cooling liquid by intermittently adjusting the speed of the driving motor 221, aiming to quickly improve the instantaneous cooling effect while ensuring the balanced flow of the cooling liquid, avoiding the occurrence of "cold zones" and "hot zones" in the tank.

[0066] The core components of this system are similar to those of other embodiments, including the bath cooling pool 100, the pickling tank 200, the refrigeration coil 140, the compression refrigeration assembly 130, the laminar flow fin plate 210, the liquid guide box 220, the stirring screw 230, and the driving motor 221. In particular, in this embodiment, pulse cooling liquid flow control technology is introduced to enhance the flowability and instantaneous cooling effect of the system's cooling liquid. The system adjusts the speed of the driving motor 221 through pulse current to intermittently increase the rotation speed of the stirring screw 230. Through this pulse regulation, the flow rate of the cooling liquid is accelerated in a short time, the stirring effect is enhanced, and the flowability and turbulence intensity of the liquid are significantly improved.

[0067] During normal operation, the driving motor maintains a constant speed to maintain the basic flow of the cooling liquid. When the system detects that the temperature of some areas rises rapidly or needs instantaneous cooling, the pulse current intermittently increases the speed of the driving motor, and the stirring screw rotates faster, thereby rapidly increasing the flow rate of the cooling liquid. With the accelerated flow of the cooling liquid, the heat exchange efficiency between the liquid in the tank and the tank wall and each area is greatly improved.

[0068] Applicable scenarios: This pulse cooling liquid flow control technology is suitable for production environments that require rapid cooling, especially in situations where local temperature may rapidly increase during pickling processes. By instantaneously accelerating the cooling liquid flow rate, the system can effectively respond to temperature fluctuations, making it suitable for efficient pickling and other processes that require precise temperature control. Through the pulse cooling liquid flow control technology of the present embodiment, the cooling efficiency of the photovoltaic aluminum profile vertical oxidation pickling tank has been significantly improved. The system can drive the motor speed through intermittent pulse regulation, accelerate the flow of the cooling liquid quickly, achieve powerful cooling and enhance the turbulence effect. This technology not only can quickly reduce the temperature, but also can effectively prevent the cooling liquid from staying in the tank, ensure the balanced flow of the liquid in the tank, avoid temperature unevenness, and improve the stability and efficiency of the pickling process.
