Description

Technical Field

[0001] The invention relates to a blower, in particular to a blower with high-efficiency energy utilization, and belongs to the technical field of blowers. Background Art

[0002] Blower is an important gas compression and delivery equipment. It compresses and delivers a large amount of gas to where it is needed through mechanical energy conversion. The main function of the blower is to provide a stable airflow for various industrial and commercial applications. Its functions include combustion support, ventilation, air exchange, cooling, etc., which can meet the gas delivery needs of different occasions. Blowers have many advantages. They have a compact structure, small footprint, easy installation and maintenance, smooth operation, low noise, and will not interfere with the surrounding environment. Blowers are widely used in various fields. In metallurgy, chemical industry and other industrial fields, blowers are used for combustion support and air supply of blast furnaces, converters and other equipment to ensure the smooth progress of the production process. In the field of environmental protection, blowers are used in the aeration system of sewage treatment plants to provide sufficient oxygen for microorganisms and promote the biochemical treatment of sewage. In addition, blowers are also widely used in food, medicine, construction and other industries to provide the required airflow for various equipment.

[0003] Existing blowers are usually unable to automatically adjust power according to real-time conditions. When the blower is running in a non-full load state, due to the inability to automatically adjust power, the blower will still run at a higher power, which will lead to energy waste. At the same time, the lack of the function of automatic power adjustment makes it impossible for the blower to respond in time when facing load changes, resulting in the equipment being unable to provide sufficient airflow when the load suddenly increases, and unable to reduce energy consumption in time when the load decreases. In addition, for blowers that need to run continuously for a long time, the inability to automatically adjust power will also increase the wear and aging rate of the equipment, thereby shortening the service life of the equipment and increasing the cost of maintenance and replacement. For this reason, a blower with efficient energy utilization is proposed. Summary of the invention

[0004] In view of this, the present invention provides a blower with efficient energy utilization to solve or alleviate one of the technical problems existing in the prior art and at least provide a beneficial option.

[0005] The technical solution of the embodiment of the present invention is implemented as follows: A blower with efficient energy utilization includes a main body assembly, wherein the main body assembly includes a sealed housing, a foot, a top plate, a fixing bolt, a turbo blower, a permanent magnet synchronous motor, an air pressure sensor, a flow sensor, an air inlet, a filter, an air outlet, a vibration sensor, and an audible and visual alarm; The bottom of the sealed shell is symmetrically fixedly connected with a foot, the top of the sealed shell is fixedly connected with a top plate by fixing bolts, the inner side wall of the sealed shell is installed with a turbine fan, the bottom of the turbine fan is installed with a permanent magnet synchronous motor, the air outlet pipe of the turbine fan is installed with an air pressure sensor and a flow sensor, the outer side wall of the sealed shell is connected with an air inlet, one end of the air inlet is installed with a filter, the outer side wall of the sealed shell is connected with an air outlet, the air outlet is connected with the air outlet pipe of the turbine fan, a vibration sensor is installed on the top of the turbine fan, and an audible and visual alarm is installed on the top of the top plate; The main body component is provided with a heat dissipation component and a control component.

[0034] Example 2

[0035] like Figure 6-Figure 7 As shown, an embodiment of the present invention provides a blower with efficient energy utilization, including a main body assembly 10, the main body assembly 10 includes a sealing shell 11, a foot 12, a top plate 13, a fixing bolt 14, a turbo fan 15, a permanent magnet synchronous motor 16, an air pressure sensor 17, a flow sensor 18, an air inlet 19, a filter 110, an air outlet 111, a vibration sensor 112 and an audible and visual alarm 113; The bottom of the sealed housing 11 is symmetrically fixedly connected with a foot 12, the top of the sealed housing 11 is fixedly connected with a top plate 13 by a fixing bolt 14, the inner wall of the sealed housing 11 is installed with a turbine fan 15, the bottom of the turbine fan 15 is installed with a permanent magnet synchronous motor 16, the outlet pipe of the turbine fan 15 is installed with an air pressure sensor 17 and a flow sensor 18, the outer wall of the sealed housing 11 is connected with an air inlet 19, one end of the air inlet 19 is installed with a filter 110, and the outer wall of the sealed housing 11 is connected with an outlet The air outlet 111 is connected to the air outlet pipe of the turbo fan 15. A vibration sensor 112 is installed on the top of the turbo fan 15. A sound and light alarm 113 is installed on the top of the top plate 13. The sealing between the sealed housing 11 and the top plate 13 ensures that external air enters from the air inlet 19. When the external air enters from the air inlet 19, dust and impurities therein are filtered through the filter 110. The turbo fan 15 is driven to work by the permanent magnet synchronous motor 16 to transport the external air to the air outlet 111, thereby completing the gas transportation work; A heat dissipation assembly 20 is disposed on the main assembly 10 .

[0036] In this embodiment, specifically: the heat dissipation component 20 includes a water cooling jacket 21, a water inlet pipe 22 and a micro pump 23; the outer wall of the permanent magnet synchronous motor 16 is fixedly connected to the water cooling jacket 21, one side of the water cooling jacket 21 is connected to the water inlet pipe 22, and the micro pump 23 is installed on the water inlet pipe 22. During the heat dissipation process, the micro pump 23 works to send the cooled water inside the heat exchanger 24 into the water cooling jacket 21, and the temperature of the permanent magnet synchronous motor 16 is reduced by the water cooling jacket 21.

[0037] In this embodiment, specifically: one end of the water inlet pipe 22 is connected to a heat exchanger 24, one side of the heat exchanger 24 is evenly and fixedly connected with cooling fins 25, the heat exchanger 24 is fixedly connected to the outer wall of the sealed shell 11, and the heat exchange area of ​​the heat exchanger 24 is increased by the cooling fins 25, so that the heat inside the heat exchanger 24 can be quickly dissipated to the external environment, thereby reducing the temperature of the circulating cooling water.

[0038] In this embodiment, specifically: the heat exchanger 24 is connected to one end of the return pipe 26 , and one end of the return pipe 26 is connected to the water cooling jacket 21 . During the heat dissipation process, the cooling water circulates through the return pipe 26 .

If the permanent magnet synchronous motor 16 is in a high-power state for a long time due to insufficient air intake or other reasons, it will cause the temperature of the permanent magnet synchronous motor 16 to be abnormal. The temperature abnormality is detected by the temperature sensor 27, and an alarm is sounded through the sound and light alarm 113.

[0040] When the present invention is working: the user sets the air volume of the blower when it is working through the controller body 37. After the blower is started, it works with the initial power. The air volume of the blower when it is working is detected by the flow sensor 18. When the air volume is lower than the preset value, the flow sensor 18 sends a signal to the controller body 37. The controller body 37 sends an instruction to the communication module 34. The communication module 34 forwards the instruction to the power regulation module 35. The power regulation module 35 is internally provided with a speed regulating resistor, which can change its own resistance value. The speed regulating resistor is connected to the voltage divider circuit of the permanent magnet synchronous motor 16. The power of the permanent magnet synchronous motor 16 is changed by changing its own resistance value. The power regulation module 35 increases the power of the permanent magnet synchronous motor 16 according to the instruction, thereby increasing the air volume. When the air volume is higher than the preset value, the controller body 37 is also used to reduce the power of the permanent magnet synchronous motor 16.

[0041] During the operation of the blower, when the external load changes and causes the air pressure at the air outlet 111 to change, the blower automatically adjusts the power of the permanent magnet synchronous motor 16 according to the load change. During the adjustment process, if the load increases and causes the air pressure at the air outlet 111 to increase, the air pressure sensor 17 sends a signal to the controller body 37, and the controller body 37 sends an instruction to the communication module 34. The communication module 34 forwards the instruction to the power adjustment module 35. The power adjustment module 35 increases the power of the permanent magnet synchronous motor 16 according to the instruction and automatically matches the load change. Similarly, if the load decreases, the blower automatically reduces the power of the permanent magnet synchronous motor 16. If the load is reduced to a preset value, the controller body 37 determines that the blower is in a no-load state, and the controller body 37 sends an instruction to make the permanent magnet synchronous motor 16 enter an idle state, maintain minimum power operation, and reduce energy consumption.

[0042] The current and voltage of the motor when it is working are detected by the current detection module 32 and the voltage detection module 33. Under the set power, if the current or voltage is significantly different from the preset value, the actual power of the blower will be affected, and an alarm will be issued through the sound and light alarm 113. If the permanent magnet synchronous motor 16 is in a high-power state for a long time due to insufficient air intake and other reasons, the temperature of the permanent magnet synchronous motor 16 will be abnormal. The temperature abnormality is detected by the temperature sensor 27, and an alarm is issued through the sound and light alarm 113. If the vibration of the turbine fan 15 is abnormal due to insufficient lubricating oil and other reasons, the vibration sensor 112 sends the vibration abnormality signal to the controller body 37, and an alarm is issued through the sound and light alarm 113.

[0043] The present invention detects the air volume of the blower when it is working through the flow sensor 18. When the air volume exceeds a preset value, the controller body 37 controls the power adjustment module 35 in the driver body 31 to reduce the power of the permanent magnet synchronous motor 16 and reduce additional energy consumption. When the air volume is lower than the preset value, the power of the permanent magnet synchronous motor 16 is increased to ensure that the air volume meets user needs.

[0044] The present invention detects the air pressure at the air outlet through the air pressure sensor 17, and determines the load change according to the air pressure. When the load increase causes the air pressure to increase, the power regulation module 35 increases the power of the permanent magnet synchronous motor 16, thereby increasing the turbine speed to match the production demand. When the load decreases, the power and turbine speed of the permanent magnet synchronous motor 16 are reduced accordingly. When the load is reduced to the set value, it is determined that the blower is in a no-load state, and the permanent magnet synchronous motor 16 enters an idle state, thereby reducing energy consumption and saving energy.

[0045] The present invention detects abnormal conditions of the blower during operation through the current detection module 32, the voltage detection module 33, the vibration sensor 112 and the temperature sensor 27. When overvoltage, overcurrent, short circuit, vibration or abnormal temperature occurs, an alarm is sounded through the sound and light alarm 113 to prevent the blower from working for a long time in an abnormal state, causing energy waste, and at the same time increasing the service life of the blower.
