Description

Technical Field

[0001] This utility model relates to the field of profile processing technology, and in particular to an air-cooling system that can quickly achieve a cooling level. Background Technology

[0002] When aluminum alloys undergo high-temperature solution treatment and are then rapidly cooled, the solute atoms cannot precipitate from the solid solution in time due to the extremely rapid cooling rate. Therefore, they are "frozen" and retained within the aluminum matrix. The solid solution formed in this state is called a supersaturated solid solution. Although thermodynamically unstable, this state can significantly improve the strength and hardness of aluminum alloys, giving them superior physical properties.

[0003] In this process, achieving rapid cooling is crucial. In the existing technology, air cooling of quenching equipment is generally used. However, it takes time to start up the air cooling of quenching equipment, especially in the hot season. Due to the high ambient temperature and the high temperature of the quenching air source, the cooling effect is delayed and the quenching effect is not achieved. Therefore, this utility model proposes an air cooling system that can quickly achieve the cooling level to solve the problems existing in the prior art. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a rapid cooling system that can quickly achieve a cooling level. This rapid cooling system absorbs a large amount of heat through the melting of ice, thereby enhancing the cooling capacity of the system. It can quickly remove the heat generated during the processing of aluminum profiles, effectively improving production efficiency. It is especially suitable for aluminum profile production processes that require high cooling speeds.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a wind-cooling system that can quickly achieve the cooling level, including a centrifugal fan and an ice box, wherein a tray is provided in the middle position inside the ice box and a drain hole is provided on the tray, and a water collection hopper is provided at one end of the bottom of the ice box and a drainage component is provided below the water collection hopper;

[0006] An air inlet is obliquely provided on one side of the top of the ice box, and the top of the ice box is connected to an ice block conveying assembly. The input end of the centrifugal fan and the side of the ice box away from the water collection hopper are connected to an air inlet pipe, and the output end of the centrifugal fan is connected to an air duct. The output end of the air duct is connected to a blower assembly.

[0007] A further improvement is that the air blowing assembly includes an air collecting plate and a nozzle. The air collecting plate is located at the output end of the air duct, and the nozzle is located at the bottom of the air collecting plate. The nozzle is equipped with an air outlet regulating valve.

[0008] A further improvement is that a first temperature sensor is provided at one end of the air inlet pipe, and a second temperature sensor is provided at the output end of the air duct. The signal output ends of the first and second temperature sensors are both connected to a PLC controller, and the control end of the PLC controller is connected to the centrifugal fan and the ice conveying assembly.

[0009] A further improvement is that the drainage component includes a drain pipe and a solenoid valve. The drain pipe is connected to the bottom of the water collection hopper, the solenoid valve is located on the drain pipe, and a liquid level sensor is provided on the upper inner side of the water collection hopper. The signal output terminal of the liquid level sensor is connected to a PLC controller, and the control terminal of the PLC controller is connected to the solenoid valve.

[0010] A further improvement is that the inlet of the air duct and the outlet of the centrifugal fan are connected by a first flange, and a flexible hose is connected between the inlet of the air duct and the first flange.

[0011] A further improvement is that the inlet of the centrifugal fan and one end of the air inlet pipe are connected by a second flange.

[0012] A further improvement is that the ice conveying assembly includes a conveying pipe and a guide pipe. The guide pipe is connected to one side of the bottom of the conveying pipe, and the output end of the guide pipe is connected to an ice box. An ice storage compartment is provided on the top side of the conveying pipe away from the guide pipe, and the top of the ice storage compartment is covered with a cap. The interior of the ice storage compartment contains ice.

[0013] A further improvement is that a spiral blade shaft is rotatably mounted inside the conveying pipe, and a motor is mounted on one side of the conveying pipe, with the output end of the motor connected to the spiral blade shaft.

[0014] A further improvement is that a gap is left between one side of the tray and one side of the ice box, and a partition block is provided on the top of the tray. Multiple sets of partition blocks are provided at equal intervals. The bottom of the ice box is inclined towards the water collection hopper.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model adds an ice box, which conveys ice blocks to the tray through an ice block conveying component. A centrifugal fan generates negative pressure, and air is introduced through the air inlet to cool the air. The air cooled by the ice blocks passes through the air inlet pipe to the centrifugal fan, and then through the air duct to the blowing component. The melting of the ice blocks can absorb a large amount of heat, thereby enhancing the cooling capacity of the air-cooling system.

The temperature signal sensed by the sensor is connected to the PLC controller, which can conveniently control the centrifugal fan speed, the ice block conveying component to start and stop supplying ice blocks, etc., according to the preset temperature value, so as to achieve precise temperature control. This facilitates more accurate control of temperature changes during the cooling process of aluminum profiles, reduces the problem of uneven cooling of aluminum profiles caused by ambient temperature fluctuations or instability of the air cooling system, helps to improve the stability and consistency of product quality, and reduces the scrap rate.

[0018] 3. In use, the water from the melting ice flows through the leak to the bottom of the ice box and is guided to the water collection hopper by the inclined surface. When the liquid level sensor detects that the liquid level is too high, the solenoid valve can be opened by the PLC controller to facilitate drainage through the drain pipe, thus avoiding the melting water from affecting the ventilation and making the use more reliable.

The air cooled by the ice blocks passes through the air inlet pipe 12 to the centrifugal fan 1, and then through the air duct 9 to the blowing assembly. The melting of the ice blocks can absorb a large amount of heat, thereby enhancing the cooling capacity of the air-cooling system.

It is especially suitable for aluminum profile production processes that require high cooling speed. Furthermore, this product features a first temperature sensor 13 installed at one end inside the air inlet duct 12 and a second temperature sensor 14 installed at the output end inside the air duct 9. The temperature signals from these sensors are connected to the PLC controller, facilitating the control of the centrifugal fan 1 speed and the start / stop of the ice delivery component to supply ice based on preset temperature values. This enables precise temperature control, allowing for more accurate control of temperature changes during the aluminum profile cooling process. It reduces uneven cooling of the aluminum profile caused by ambient temperature fluctuations or instability in the air-cooling system, contributing to improved product quality stability and consistency, and reducing the scrap rate.
