Technical Field

[0001] The utility model relates to the technical field of xxx, in particular to a multi-stage speed regulation rapid cooling device based on high-temperature materials. Background Technique

[0002] The lime kiln is a lime production facility with a long historical tradition. By using the decomposition reaction of calcium carbonate in limestone under high-temperature conditions, the molecular structure of calcium carbonate in limestone is destroyed, releasing carbon dioxide gas, and the remaining part is converted into calcium oxide, that is, quicklime. Quicklime has a wide range of applications in many fields, such as construction, agriculture, water treatment, and metallurgy.

[0003] In the production process of the lime kiln, after the materials are subjected to high-temperature calcination, the temperature at the time of discharging can be as high as 300 - 400 °C. In order to avoid the threat of the materials to the equipment and the environment, these high-temperature materials must be cooled quickly and effectively. However, the traditional method is to use a fixed-frequency cooling fan to cool the materials. During the discharging period and for some time afterwards, the fan of the cooling device continuously runs at a high frequency to quickly remove the hot air in the silo, resulting in high energy consumption and uneven cooling problems.

[0004] Based on this, the utility model designs a multi-stage speed regulation rapid cooling device based on high-temperature materials to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a multi-stage speed regulation rapid cooling device based on high-temperature materials to solve the problems raised in the above background technique.

[0009] A frequency converter, the frequency converter for receiving the frequency signal from the multi-stage speed relay is electrically connected to the multi-stage speed relay;

[0010] A silo, the silo for conveying high-temperature materials is fixedly installed in the lime kiln;

[0011] A cooling fan, the cooling fan for extracting the high-temperature hot air in the silo is installed on one side of the silo, the cooling fan is electrically connected to the frequency converter, and the operating frequency of the cooling fan is controlled by the frequency converter.

[0012] Preferably, the time control switch sends a high-frequency signal to the frequency converter through a multi-speed relay, and the frequency converter controls the high-power operation of the cooling fan through the high-frequency signal.

[0013] Preferably, after the high-power operation stage, the time control switch triggers a switching signal, the multi-speed relay sends a low-frequency signal to the frequency converter through the switching signal, and the cooling fan reduces the operating frequency through the low-frequency signal.

[0014] Preferably, the high-frequency signal sent by the multi-speed relay is 50 Hz, and the low-frequency signal sent by the multi-speed relay is 20 Hz.

[0015] Preferably, the multi-speed relay is the core control component, and the multi-speed relay adjusts the output frequency through the time control switch.

[0016] Preferably, the multi-speed relay controls the operating frequency of the cooling fan through the time control switch.

[0017] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0018] First, by setting the time control switch and the multi-speed relay, the present utility model can automatically adjust the operating frequency of the cooling fan according to the cooling requirements of the material, thereby achieving the dual goals of rapid cooling and energy saving. Compared with the traditional fixed-frequency cooling fan, the present utility model can effectively reduce energy consumption and reduce unnecessary power waste. Moreover, through multi-speed adjustment, it can flexibly adjust the power output of the cooling fan according to the temperature change of the material and different stages of the cooling process. When the material temperature is high, it operates at a high frequency to quickly reduce the temperature; after the material temperature gradually decreases, it automatically switches to low-frequency operation to maintain an appropriate cooling speed and avoid energy waste caused by overcooling.

[0019] Second, the multi-speed relay of the present utility model, as the core control component, can accurately control the frequency signal output by the frequency converter to ensure that the operating frequency of the cooling fan matches the cooling requirements of the material. This precise control not only improves the cooling efficiency but also extends the service life of the cooling fan and reduces the maintenance cost. It can not only effectively solve the problems of high energy consumption and uneven cooling in traditional cooling methods but also flexibly adjust the cooling speed according to actual production needs to achieve the goal of energy saving and high efficiency.

[0024] Please refer to Figure 1-2 , a multi-speed adjustment rapid cooling device for high-temperature materials, including:

The cooling fan 5 is electrically connected to the frequency converter 3, and the operating frequency of the cooling fan 5 is controlled by the frequency converter 3, for extracting the high-temperature hot air in the silo.

[0030] Further, the time control switch 1 sends a high-frequency signal to the frequency converter 3 through the multi-speed relay 2. The frequency converter 3 controls the high-power operation of the cooling fan 5 through the high-frequency signal. When the time control switch 1 is started, the multi-speed relay 2 immediately sends a high-frequency 50 Hz signal to the frequency converter 3, so that the cooling fan 4 operates at high power to quickly extract the high-temperature hot air in the silo during and within 30 minutes after discharging, effectively preventing the equipment from overheating.

[0031] Further, after the high-power operation stage, the time control switch 1 triggers a switching signal. The multi-speed relay 2 sends a low-frequency signal to the frequency converter 3 through the switching signal. The cooling fan 5 reduces the operating frequency through the low-frequency signal. After the high-power operation stage ends, the time control switch 1 triggers a switching signal, and the multi-speed relay 2 then sends a low-frequency signal of 20 Hz to the frequency converter 3, causing the cooling fan 4 to automatically reduce the operating frequency and enter the mild cooling stage, running continuously for 1 hour to save electricity while ensuring the cooling effect and avoiding excessive cooling of the material.

[0032] Further, the high-frequency signal sent by the multi-speed relay 2 is 50 Hz, and the low-frequency signal sent by the multi-speed relay 2 is 20 Hz.

[0033] Specifically, during the discharging period and a preset time period thereafter, such as within 30 minutes, after the time control switch 1 is started, the multi-speed relay 2 sends a high-frequency signal of 50 Hz to the frequency converter 3, causing the cooling fan 5 to operate at high power and quickly extract the high-temperature hot air in the silo 4. After the high-power operation stage ends, the time control switch 1 triggers a switching signal, and the multi-speed relay 2 then sends a low-frequency signal of 20 Hz to the frequency converter 3, causing the cooling fan 5 to automatically reduce the operating frequency and enter the mild cooling stage, running continuously for the preset time of 1 hour.

[0034] Further, the multi-speed relay 2 is the core control component, which can flexibly respond to the instructions of the time control switch 1, output signals of different frequencies, and achieve precise adjustment of the operating frequency of the cooling fan 5 to meet the cooling requirements in different production stages. The multi-speed relay 2 adjusts the output frequency through the time control switch 1, and the multi-speed relay 2 can flexibly adjust the output frequency according to the instructions of the time control switch 1.

[0036] Working principle of the utility model: When in use, first of all, the time control switch 1 is automatically started according to the preset discharging time, and issues an instruction to control the time period of the cooling process. During the discharging period and within 30 minutes after that, the time control switch 1 sends a high-frequency signal, usually 50 Hz, to the frequency converter 3 through the multi-speed relay 2, so as to ensure that the cooling fan 5 operates at a high power. In this way, the high-temperature hot air in the silo 4 can be quickly evacuated, effectively preventing the equipment from overheating. After the high-power operation stage ends, the time control switch 1 triggers a switching signal, and the multi-speed relay 2 immediately sends a low-frequency signal, usually 20 Hz, to the frequency converter 3. The cooling fan 5 reduces the operating frequency through the low-frequency signal and enters the mild cooling stage, running for 1 hour. The purpose of this stage is to save electricity and avoid excessive cooling of the material while ensuring the cooling effect.
