Description

Technical Field

[0001] This utility model relates to the technical field of annular cooler fan accessories, specifically to an annular cooler fan system. Background Technology

[0002] The annular cooler fan is one of the main pieces of equipment in the sintering cooling process line. Its function is to blow cold air into the air box under the annular cooler trolley to cool the sintered ore unloaded from the sintering machine. The annular cooler fan consists of a drive motor, fan, silencer, support base, reducer, electric butterfly valve, compensator, etc. The annular cooler fan rotates under the drive motor, and the support base provides fixed support. A non-metallic compensator is installed between the fan and the air box to eliminate the elongation of the air duct caused by heat and prevent vibration from being transmitted to the air box.

[0003] In existing fan regulating devices, the fan airflow is adjusted by a worker driving a butterfly valve to change the damper opening. However, adjusting the damper opening via an electric butterfly valve does not reduce the fan speed; most of the motor's output power is wasted, resulting in low power efficiency. When the damper opening is sufficiently small, the air cannot be effectively exhausted because the motor speed remains constant, thus reducing the fan's lifespan.

[0004] In summary, there is an urgent need for an annular cooler fan system to solve, or at least partially solve, the problems existing in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a ring cooler fan system, which aims to solve the problems of low fan power consumption utilization and low automation in existing fan regulation devices. The specific technical solution is as follows:

[0006] A ring cooler fan system includes a blower mechanism, a temperature sensing component and a control component, a ring cooler discharge chute and a plate feeder. The plate feeder is located downstream of the ring cooler discharge chute. The control component is electrically connected to both the temperature sensing component and the blower mechanism. The temperature sensing component is installed on the outer wall of the ring cooler discharge chute. The outlet of the blower mechanism is connected to the input of the upper air box of the ring cooler, and the inlet of the blower mechanism is connected to the outside.

[0007] Furthermore, the temperature sensing component includes a temperature sensor, which is electrically connected to the control component via a connecting wire.

[0008] Furthermore, two temperature sensors are arranged, one on each side of the bottom of the discharge chute of the annular cooler.

[0009] Preferably, the blower mechanism includes a centrifugal fan and a drive motor, with the output end of the drive motor connected to the power input end of the centrifugal fan; the input end of the centrifugal fan is connected to the outside, and the output end of the centrifugal fan is connected to the air box of the annular cooler; the control component is electrically connected to the drive motor.

[0010] Furthermore, the blower mechanism also includes a non-metallic connector, the first end of which is connected to the output end of the centrifugal fan, and the second end of which is connected to the air box of the annular cooler.

[0011] Furthermore, the non-metallic connector is a rubber bellows.

[0012] Furthermore, the blower mechanism also includes a reducing pipe, the first end of which is connected to the output end of the centrifugal fan, and the second end of which is connected to the air box of the annular cooler.

However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0026] Example:

[0027] See Figures 1-3 This embodiment provides a ring cooler fan system, which includes a blower mechanism 1, a temperature sensing component 2, a control component 3, a ring cooler discharge chute 4, and a plate feeder 5. The plate feeder 5 is located downstream of the ring cooler discharge chute 4. The control component 3 is electrically connected to the temperature sensing component 2 and the blower mechanism 1. The temperature sensing component 2 is installed on the outer wall of the ring cooler discharge chute 4. The air outlet of the blower mechanism 1 is connected to the input end of the upper air box of the ring cooler, and the air inlet of the blower mechanism 1 is connected to the outside.

[0028] Specifically, control component 3 is a power amplifier, and temperature sensing component 2 is a temperature sensor. The temperature sensor is connected to the power amplifier via a guide. The power amplifier has three connection terminals: the first terminal is the signal input terminal, the second terminal is the power supply terminal, and the third terminal is the output terminal. The temperature sensor is connected to the signal input terminal of the power amplifier via a wire, the power supply terminal is connected to an external power source, and the output terminal is connected to the blower mechanism 1 via a wire.

[0029] It is known that the voltage across the temperature sensor changes with temperature variations, which in turn changes the voltage transmitted to the signal input terminal via the wires. This change, after being amplified by the power amplifier, leads to a change in the output voltage. The power amplifier directly amplifies or reduces this voltage, thus controlling the power of the blower mechanism 1. No manual adjustment or control is required, and the power of the blower mechanism 1 is reduced when a lower airflow is needed, saving energy.

[0030] In another specific embodiment of this utility model, it includes a blower mechanism 1, a temperature sensing component 2, a control component 3, an annular cooler discharge chute 4, and a plate feeder 5. The plate feeder 5 is located downstream of the annular cooler discharge chute 4. The control component 3 is electrically connected to both the temperature sensing component 2 and the blower mechanism 1. The temperature sensing component 2 is installed on the outer wall of the annular cooler discharge chute 4. The temperature sensing component 2 is used to detect the temperature of the outer wall of the annular cooler discharge chute 4 and generate a temperature detection signal. The temperature sensing component 2 is also used to send the temperature detection signal to the control component 3. The control component 3 is used to receive the temperature detection signal and send a frequency conversion control signal to the blower mechanism 1. The blower mechanism 1 is electrically connected to the control component 3 and adjusts its power in response to the frequency conversion control signal. The air outlet of the blower mechanism 1 is connected to the input end of the upper air box of the annular cooler, and the air inlet of the blower mechanism 1 is connected to the outside. Specifically, the blower mechanism 1 is used to blow air into the air box of the ring cooler to cool the sintered ore in the ring cooler. The cooled ore is discharged from the discharge chute 4 of the ring cooler and transported away by the plate feeder 5.

[0031] It is understood that the temperature sensing component 2 is used to detect the temperature at the discharge chute 4 of the annular cooler, and converts the temperature signal into an electrical signal before sending it out. The control component 3 receives the electrical signal sent by the temperature sensing component 2 and outputs a corresponding electrical signal according to the strength of the electrical signal. The blower mechanism 1 receives the electrical signal sent by the control component 3 and operates at the corresponding power to increase or decrease the air volume output by the blower mechanism 1. Thus, the temperature inside the annular cooler is automatically detected by the temperature sensing component 2, and the blower mechanism 1 is controlled by the control component 3 to deliver the corresponding air volume. When the temperature received by the temperature sensing component 2 is higher, the corresponding electrical signal sent by the temperature sensing component 2 is stronger, and the control component 3 increases the air volume of the blower mechanism 1 accordingly. Conversely, when the temperature received by the temperature sensing component 2 is lower, the corresponding electrical signal sent by the temperature sensing component 2 is weaker, and the control component 3 decreases the air volume of the blower mechanism 1 accordingly. This allows for automatic adjustment of the air volume. During the adjustment process, the higher the temperature inside the annular cooler, the higher the output power of the blower mechanism 1; conversely, the lower the temperature inside the annular cooler, the lower the output power of the blower mechanism 1. Because the output power of the blower mechanism 1 can be adjusted, when the temperature inside the annular cooler is at a low temperature, it saves a significant amount of energy compared to the traditional valve-controlled structure, thus improving the energy utilization rate of the blower mechanism 1.

[0032] It is worth noting that the control component 3 can operate under adaptive conditions. After receiving the temperature signal, it adjusts the power according to the indicated power corresponding to the temperature signal. For example, when the temperature is between 200 and 260 degrees Celsius, the power is 10 kW; when the temperature is between 260 and 320 degrees Celsius, the power is 12 kW. The control component 3 can also be a PLC processor, which directly controls the blower mechanism 1 to achieve stepless adjustment of the power of the blower mechanism 1.

[0033] Furthermore, the temperature sensing component 2 includes a temperature sensor, which is electrically connected to the control component 3 via a connecting wire.

[0034] It is known that by installing a temperature sensor below the discharge hopper of the annular cooler, with the sensor probe facing inwards, the temperature of the sintered ore being cooled inside the annular cooler is detected by the temperature sensor, and the temperature signal is converted into an electrical signal output. The higher the temperature, the stronger the corresponding electrical signal output, and vice versa.

[0035] Furthermore, two temperature sensors are arranged, one on each side of the bottom of the annular cooler discharge chute 4.

[0036] It is understood that by arranging two temperature sensors on both sides of the bottom of the annular cooler discharge chute 4, the two temperature sensors detect the temperature on both sides of the bottom of the annular cooler discharge chute 4. Both temperature sensors simultaneously send electrical signals to the control component 3. The control component 3 takes the average of the two electrical signals as the input signal and sends an electrical signal to the blower mechanism 1. By taking the average of the electrical signals from the two temperature sensors, the detection of the internal temperature of the annular cooler is more accurate. This prevents the blower mechanism 1 from operating at excessively high or low power due to a large temperature difference between the two sides of the annular cooler.

[0037] Preferably, the blower mechanism 1 includes a centrifugal fan 11 and a drive motor 12. The output end of the drive motor 12 is connected to the power input end of the centrifugal fan 11. The input end of the centrifugal fan 11 is connected to the outside, and the output end of the centrifugal fan 11 is connected to the air box of the air cooler. The control component 3 is electrically connected to the drive motor 12.

[0038] It is known that the drive motor 12 is electrically connected to the control component 3. The drive motor 12 responds to the electrical signals emitted by the control component 3. The stronger the signal emitted by the control component 3, the faster the drive motor 12 rotates, and vice versa. The drive motor 12 drives the centrifugal fan 11 to rotate, thereby conveying cold air from the outside to the air box of the annular cooling fan, and then conveying it to the interior of the annular cooling fan to cool the sintered ore inside the annular cooling fan.

[0039] It is worth noting that in this embodiment, the control component 3 is a frequency converter and the drive motor 12 is a frequency converter. The frequency converter is used to receive the electrical signal emitted by the temperature sensor and emit an electrical signal to control the rotation of the frequency converter. The stronger the electrical signal emitted by the temperature sensor, the higher the temperature inside the ring cooler fan. The frequency converter then controls the speed of the frequency converter motor to be faster, so as to increase the speed of the centrifugal fan 11, thereby increasing the blowing efficiency and cooling the sintered ore in the ring cooler fan as quickly as possible.

[0040] It should be noted that, in this application, a stronger electrical signal refers to a larger current, a higher voltage, or a higher frequency of a pulse signal, while a weaker electrical signal refers to a smaller current, a lower voltage, or a lower frequency of a pulse signal.

[0041] Of course, in some other embodiments, the control component 3 can also be a power amplifier, and the drive motor 12 can also be a DC motor. The power amplifier amplifies the weak electrical signal received from the temperature sensor into a strong electrical signal and sends it to the DC motor to directly control the output power of the DC motor, thereby controlling the speed of the DC motor.

[0042] It should be noted that in this embodiment, the temperature sensing component 2 can be electrically connected to the control component 3 via wires, and the control component 3 is also connected to the blower mechanism 1 via wires. The advantages of connecting via wires are low cost, stable signal transmission, and low failure rate.

[0043] It is worth noting that in some other embodiments, a first signal transmitter may also be arranged at the temperature sensing component 2, a first signal receiver and a second signal transmitter may be arranged at the control component 3, and a second signal receiver may be arranged at the blower mechanism 1. The temperature sensing component 2 emits an electrical signal through the first signal transmitter, the control component 3 receives the electrical signal emitted by the first signal transmitter through the first signal receiver, and the blower mechanism 1 receives the signal emitted by the second signal transmitter through the second signal receiver and responds accordingly. It can be understood that the arrangement of the first signal transmitter, first signal receiver, second signal transmitter, and second signal receiver enables wireless connection between the temperature sensing component 2, the control component 3, and the blower mechanism 1, which has the advantage of facilitating installation.

[0044] Furthermore, the blower mechanism 1 also includes a non-metallic connector 13. The first end of the non-metallic connector 13 is connected to the output end of the centrifugal fan 11, and the second end of the non-metallic connector 13 is connected to the air box of the annular cooler. Specifically, the non-metallic connector 13 is a rubber bellows.

[0045] It is known that the blower mechanism 1 and the annular cooler are connected by a non-metallic connector 13. During operation, the temperature of the annular cooler changes, causing the air box to expand and contract accordingly. Since the position of the blower mechanism 1 remains fixed, the non-metallic connector 13 compensates for the dimensional changes caused by thermal expansion and contraction of the annular cooler. This prevents gaps from forming between the blower mechanism 1 and the air box of the annular cooler, as gaps would lead to air leakage and wasted power. Furthermore, it prevents damage to the air box or the blower mechanism 1 due to overheating and expansion.

[0046] Furthermore, the blower mechanism 1 also includes a reducing pipe 14, the first end of which is connected to the output end of the centrifugal fan 11, and the second end of which is connected to the air box of the annular cooler. Specifically, the first end of the reducing pipe 14 is arranged as a square flange joint, and the second end of the reducing pipe 14 is arranged as a round flange joint.

[0047] It is known that the outlet of the centrifugal fan 11 is generally square, while the interface with the annular cooler is round. Therefore, by setting the reducing pipe 14, a smooth transition can be easily formed between the centrifugal fan 11 and the annular cooler's air box. On the one hand, this facilitates the connection between the centrifugal fan 11 and the annular cooler's air box; on the other hand, the smooth transition helps reduce air resistance.

[0048] Furthermore, the blower mechanism 1 also includes a silencer 15, which is arranged at the input end of the centrifugal fan 11. The first end of the silencer 15 is connected to the outside, and the second end of the silencer 15 is connected to the input end of the centrifugal fan 11.

[0049] It is known that the silencer 15 is connected to the air inlet of the centrifugal fan 11. The silencer 15 isolates the noise generated inside the centrifugal fan 11, reduces the transmission of noise to the outside when the equipment is running, and improves the comfort of the working environment for the operators.

[0050] In a preferred embodiment, the blower mechanism 1 includes an axial flow fan, the input end of which is connected to the outside, the output end of which is connected to the air box of the annular cooler, and the axial flow fan is electrically connected to the control component 3.

[0051] It is known that the control component 3 sends an electrical signal, the axial flow fan receives the electrical signal sent by the control component 3, and responds accordingly.

[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
