Description

Technical Field

[0001] This invention relates to the field of fan cooling technology, and in particular to a dual cooling system for an air-suspended fan and an energy-saving operation method. Background Technology

[0002] Air suspension fans are widely used in industrial production, sewage treatment and other fields. They generate a lot of heat during operation. If they cannot be dissipated in a timely and effective manner, it will affect the operating efficiency of the fan, shorten its service life, and in severe cases, it may lead to equipment failure.

[0003] Existing air suspension fan cooling systems mostly use a single cooling method, which has limited cooling effect and makes it difficult to flexibly adjust the cooling intensity according to temperature changes. At the same time, during the installation and fixing of the fan, the fixing parts are prone to loosening, which not only affects the stability of the equipment but may also generate noise due to vibration. In addition, the temperature detection range is fixed, which cannot comprehensively monitor the temperature distribution around the fan, resulting in inaccurate judgment of the cooling timing and energy waste. Summary of the Invention

[0004] This invention relates to a dual cooling system for an air-suspended fan and an energy-saving operation method, which solves the problems of poor cooling effect, easy loosening of equipment, limited temperature detection range, and serious energy waste in existing cooling systems.

[0005] This invention provides a dual cooling system for an air-suspended fan and an energy-saving operation method, specifically including: a base; a seat body is placed on the base, and first fixed seats are symmetrically slidable on the seat body. Reinforcing plates are symmetrically welded inside the first fixed seats. Each first fixed seat is threaded with a positioning screw for positioning the first fixed seat on the seat body. Each first fixed seat is inserted with a first fixing screw, and the first fixing screw is fixed on the base.

[0006] Furthermore, the adjustment point of the positioning screw is a cylindrical structure, and an auxiliary block is welded on each first fixed seat. The outer side of the auxiliary block is in elastic contact with the adjustment point of the positioning screw.

[0007] Furthermore, a mounting base is fixed to the base body by four bolts and nuts. A limiting plate slides on the inner side of the mounting base. The bottom end face of the limiting plate contacts the nuts on the four bolts. A second fixing screw is inserted into the limiting plate and the second fixing screw is threaded onto the base body.

[0008] Furthermore, the second fixing screw is provided with an adjustment groove, which is a hexagonal groove structure.

[0009] Furthermore, an air suspension fan is installed on the mounting base. The air suspension fan has dual cooling channels. A first flange is welded to the exhaust pipe of the air suspension fan. A second flange is fixed to the first flange. A connecting pipe for connecting to the exhaust pipe is welded to the second flange. Positioning rods are symmetrically welded to the first flange. The positioning rods pass through the second flange. One end of the positioning rod has an arc-shaped structure. When the positioning rod passes through the second flange, the second flange is aligned with the fixing hole on the first flange.

[0010] Furthermore, a second fixing seat is symmetrically fixed on the base by a third fixing screw. The second fixing seat is snapped and fixed on the air suspension fan. The second fixing seat is a stabilizing component of the air suspension fan. The second fixing seat and the third fixing screw together form a fixing assembly.

[0011] Furthermore, a connecting block is symmetrically fixed to the top surface of the base, and an adjusting rod is rotatably mounted on the connecting block. The left and right ends of the adjusting rod are threadedly connected to a base block, and the thread directions of the left and right ends of the adjusting rod are opposite. The base blocks are all rectangular block structures, and the bottom end of the base blocks is in contact with the top end of the base. A temperature sensor is fixed on each base block.

[0012] Furthermore, a first gear is welded onto the adjusting rod, a motor is fixed onto the connecting block, and a second gear is fixed onto the output shaft of the motor. The second gear meshes with the first gear. The connecting block, adjusting rod, base block, temperature sensor, first gear, motor, and second gear together constitute the adjusting assembly.

[0013] Furthermore, a control box is installed on the upper surface of the base, and a microprocessor is installed inside the control box. The microprocessor is electrically connected to the temperature sensor, the motor, and the air suspension fan.

[0014] An energy-saving operation method for a dual-cooling system for an air-suspended fan includes the following steps:

[0015] 01. Place the base on the base, slide and adjust the two first fixed seats to the appropriate position, tighten the positioning screw to position, and then fix the first fixed seat on the base through the first fixed screw. At this time, the auxiliary block and the adjustment point of the positioning screw are in elastic contact to prevent the positioning screw from loosening.

[0016] 02. Secure the mounting base to the base body with bolts and nuts, slide the limiting plate to press the nut, and then tighten the second fixing screw onto the base body to achieve secondary fixing of the nut; subsequently, install the air suspension fan on the mounting base;

[0017] 03. Fix the second fixing seat to the base using the third fixing screw, so that the second fixing seat is snapped into place to fix the air suspension fan;

[0018] 04. Connect the connecting pipe to the first flange of the air suspension fan through the second flange, pass the positioning rod through the second flange and guide the fixing hole to align, and complete the pipe connection;

[0019] 05. Turn on the control box, start the microprocessor, control the motor to rotate back and forth, drive the adjusting rod to rotate through gear transmission, so that the two temperature sensors move synchronously in opposite directions, expanding the detection range. The temperature sensors collect temperature data in real time and transmit it to the microprocessor. The microprocessor automatically controls the start and stop of the air suspension fan according to the comparison results of temperature parameters and thresholds, so as to achieve energy-saving cooling operation.

[0020] This invention provides a dual-cooling system for an air-suspended fan and an energy-saving operation method, which has the following beneficial effects:

[0021] This application's air-suspended fan is equipped with dual cooling channels, which significantly enhances heat dissipation capacity compared to traditional single cooling methods. It can quickly dissipate the heat generated during fan operation, ensuring that the fan always operates at a suitable temperature, effectively improving operating efficiency and extending equipment lifespan. At the same time, a temperature sensor collects ambient temperature data in real time and transmits it to a microprocessor. The microprocessor automatically controls the fan to start or stop based on the comparison results between temperature parameters and preset thresholds, avoiding energy waste caused by ineffective operation and achieving energy-saving operation.

[0022] The first fixed seat on the base of this application can be slidably adjusted in position. Together with the positioning screw and the first fixed screw, it can flexibly adapt to different installation requirements and improve the fixing flexibility. When the first flange and the second flange at the exhaust pipe of the air suspension fan are connected, the arc-shaped structure above the positioning rod can play a guiding role, so that the second flange can quickly and accurately align with the first flange, and automatically achieve the alignment of the fixing holes, without the need for repeated manual adjustments, which greatly simplifies the pipe connection steps. The hexagonal adjustment groove on the second fixed screw facilitates disassembly operations using a hex wrench, further improving the convenience of installation and maintenance.

[0023] The reinforcing plate inside the first fixing seat enhances the structural strength of the fixing seat itself. The auxiliary block and the positioning screw adjustment point make elastic contact, effectively reducing the probability of the positioning screw loosening. The limiting plate presses and fixes the nut on the bolt, preventing the nut from loosening and causing vibration, noise, or safety accidents. The second fixing seat of the fixing component clamps and fixes the fan, further improving the stability of the fan after installation and reducing vibration during operation. The adjustment component drives the adjustment rod to rotate through the gear transmission driven by the motor, realizing the synchronous reverse movement of the two temperature sensors, expanding the temperature detection range, enabling the microprocessor to fully grasp the temperature distribution, accurately determine the cooling timing, ensure the efficient operation of the cooling system, and improve the overall safety of the equipment.

[0040] Example 1: Please refer to Figures 1 to 8 :

[0041] This invention proposes a dual cooling system for an air-suspended fan and an energy-saving operation method, comprising: a base 1; a seat body 2 placed on the base 1, with first fixed seats 202 symmetrically sliding on the seat body 2, and reinforcing plates 201 symmetrically welded inside the first fixed seats 202; each first fixed seat 202 is threadedly connected to a positioning screw 203 for positioning the first fixed seat 202 on the seat body 2; each first fixed seat 202 is inserted with a first fixing screw 204; the first fixing screw 204 is fixed to the base 1; when adjusting the fixed position, the positioning screw 203 is loosened to adjust the position of the first fixed seat 202; after adjustment, the positioning screw 203 is tightened and fixed by the first fixing screw 204, thus improving the flexibility of fixing.

[0042] The adjustment point of the positioning screw 203 is a cylindrical structure. Each first fixed seat 202 is welded with an auxiliary block 205. The outer side of the auxiliary block 205 is in elastic contact with the adjustment point of the positioning screw 203. Under the action of the auxiliary block 205, the probability of the positioning screw 203 loosening can be reduced, thus ensuring the stability of the device.

[0043] The mounting base 207 is fixed to the base 2 by four bolts 206 and nuts. The mounting base 207 has a sliding limit plate 3. The bottom end of the limit plate 3 contacts the nuts on the four bolts 206. A second fixing screw 301 is inserted into the limit plate 3 and screwed onto the base 2. By pressing the nuts on the bolts 206 with the limit plate 3, the electric loosening of the nuts can be reduced, thus avoiding noise and dangerous accidents caused by loose nuts.

[0044] The mounting base 207 is equipped with an air suspension fan 4, which has dual cooling channels. A first flange 401 is welded to the exhaust pipe of the air suspension fan 4. A second flange 402 is fixed to the first flange 401. A connecting pipe 403 for connecting to the exhaust pipe is welded to the second flange 402. A positioning rod 404 is symmetrically welded to the first flange 401. The positioning rod 404 passes through the second flange 402. The upper end of the positioning rod 404 has an arc-shaped structure. When the positioning rod 404 passes through the second flange 402, the second flange 402 is aligned with the fixing hole on the first flange 401. The first flange 401, the second flange 402 and the positioning rod 404 improve the convenience and sealing of the pipe connection.

[0045] The base 1 is symmetrically fixed with a second fixing seat 501 by a third fixing screw 502. The second fixing seat 501 is snapped and fixed on the air suspension fan 4. The second fixing seat 501 is a stabilizing component of the air suspension fan 4. The second fixing seat 501 and the third fixing screw 502 together form a fixing component 5. Under the action of the second fixing seat 501, the stability of the air suspension fan 4 can be improved and the noise caused by vibration can be reduced.

[0046] The base 1 has a connecting block 701 symmetrically fixed to its top surface. An adjusting rod 702 is rotatably mounted on the connecting block 701. The left and right ends of the adjusting rod 702 are threadedly connected to a base block 703. The threads of the left and right ends of the adjusting rod 702 are in opposite directions. The base blocks 703 are all rectangular block structures. The bottom surface of the base blocks 703 is in contact with the top surface of the base 1. A temperature sensor 704 is fixed on each base block 703.

[0047] The adjusting rod 702 is welded with a first gear 705, and a motor 706 is fixed on the connecting block 701. A second gear 707 is fixed on the output shaft of the motor 706. The second gear 707 meshes with the first gear 705. The connecting block 701, adjusting rod 702, base block 703, temperature sensor 704, first gear 705, motor 706, and second gear 707 together form the adjusting assembly 7. When adjusting the position of the two temperature sensors 704, the motor 706 is driven to rotate. Under the meshing transmission of the second gear 707 and the first gear 705, the adjusting rod 702 can be rotated. Under the adjustment of the adjusting rod 702, the two temperature sensors 704 can move synchronously in opposite directions. Through the synchronous reverse movement of the two temperature sensors 704, the detection range can be expanded.

[0048] The base 1 has a control box 6 installed on its upper surface. The control box 6 contains a microprocessor 601, which is electrically connected to a temperature sensor 704, a motor 706, and an air levitation fan 4. In use, the temperature sensor 704 transmits temperature parameters to the microprocessor 601 in real time. When the temperature parameter exceeds the threshold in the microprocessor 601, the microprocessor 601 controls the air levitation fan 4 to work. When the temperature parameter is lower than the threshold in the microprocessor 601, the microprocessor 601 controls the air levitation fan 4 to stop working. At the same time, the microprocessor 601 controls the motor 706 to rotate back and forth to adjust the position of the two temperature sensors 704, thereby expanding the detection range.

[0049] An energy-saving operation method for a dual-cooling system for an air-suspended fan includes the following steps:

[0050] 01. Place the base 2 on the base 1, slide and adjust the two first fixed seats 202 to the appropriate position, tighten the positioning screw 203 for positioning, and then fix the first fixed seat 202 on the base 1 by the first fixed screw 204. At this time, the auxiliary block 205 is in elastic contact with the adjustment point of the positioning screw 203 to prevent the positioning screw 203 from loosening.

[0051] 02. Fix the mounting base 207 to the base body 2 with bolts 206 and nuts, slide the limiting plate 3 to press the nut, and then tighten the second fixing screw 301 onto the base body 2 to achieve secondary fixing of the nut; then, install the air suspension fan 4 on the mounting base 207;

[0052] 03. The second fixing seat 501 is fixed to the base 1 by the third fixing screw 502, so that the second fixing seat 501 is snapped into and fixed to the air suspension fan 4;

[0053] 04. Connect the connecting pipe 403 to the first flange 401 of the air suspension fan 4 through the second flange 402. The positioning rod 404 passes through the second flange 402 and guides the fixing hole to be aligned, thus completing the pipe connection.

[0054] 05. Turn on the control box 6, start the microprocessor 601, control the motor 706 to rotate back and forth, drive the adjusting rod 702 to rotate through gear transmission, so that the two temperature sensors 704 move synchronously in opposite directions, expand the detection range, and the temperature sensors 704 collect temperature data in real time and transmit it to the microprocessor 601. The microprocessor 601 automatically controls the start and stop of the air suspension fan 4 according to the comparison result of the temperature parameters and the threshold, so as to achieve energy-saving cooling operation.

[0055] Example 2, based on Example 1, such as Figures 1-8 As shown, the second fixing screw 301 is provided with an adjustment groove 302. The adjustment groove 302 is a hexagonal groove structure. When disassembling the second fixing screw 301, a hexagonal wrench can also be inserted into the adjustment groove 302 for disassembly, which improves the convenience of disassembling the second fixing screw 301.

[0056] The working principle of this embodiment is as follows: First, place the base 2 on the base 1, slide and adjust the two first fixing seats 202 to a suitable position, tighten the positioning screw 203 for positioning, and then fix the first fixing seat 202 on the base 1 by the first fixing screw 204. At this time, the auxiliary block 205 is in elastic contact with the adjustment point of the positioning screw 203 to prevent the positioning screw 203 from loosening. Next, fix the mounting seat 207 on the base 2 by the bolt 206 and nut, slide the limiting plate 3 to press the nut, and then tighten the second fixing screw 301 on the base 2 to achieve secondary fixing of the nut. Subsequently, install the air suspension fan 4 on the mounting seat 207, and fix the second fixing seat 501 on the base 1 by the third fixing screw 502, so that the second fixing seat 501 is fixed on the base 1. The fixed base 501 is snapped into the fixed air suspension fan 4; the connecting pipe 403 is connected to the first flange 401 of the air suspension fan 4 through the second flange 402, and the positioning rod 404 passes through the second flange 402 and guides the fixing hole to be aligned, thus completing the pipe connection; finally, the control box 6 is turned on, the microprocessor 601 is started, and the motor 706 is controlled to rotate back and forth, which drives the adjusting rod 702 to rotate through gear transmission, so that the two temperature sensors 704 move synchronously in opposite directions, expanding the detection range. The temperature sensors 704 collect temperature data in real time and transmit it to the microprocessor 601. The microprocessor 601 automatically controls the start and stop of the air suspension fan 4 according to the comparison result of the temperature parameters and the threshold, so as to achieve energy-saving cooling operation. The assembly and operation preparation of the entire system is completed.
