Description

Technical Field

[0001] This invention relates to the field of automotive air conditioning fan performance testing technology, specifically to an automotive air conditioning fan performance testing device. Background Technology

[0002] As a core component of the automotive thermal management system, the air conditioning fan's airflow intensity, uniformity, and dust removal capability directly affect the air conditioning's cooling efficiency, condenser heat dissipation, and system lifespan. For example, insufficient fan airflow can lead to decreased condenser heat dissipation efficiency, while poor dust removal capability can easily cause air conditioning malfunctions due to dust accumulation on the condenser. With the automotive industry's increasing demands for energy efficiency and comfort, fan performance testing needs to cover core requirements such as "cooling condition simulation, multi-point airflow detection, and dust removal performance evaluation."

[0003] Traditional testing equipment often targets single operating conditions or single indicators, failing to simulate the actual working environment of automotive air conditioning systems. This results in significant discrepancies between test data and actual performance. Most devices only test the fan's idle airflow, neglecting to consider related components such as the condenser and air compressor, thus failing to recreate the real-world scenario of the "fan-condenser" working in tandem and hindering effective product optimization. One of the core functions of automotive air conditioning fans is to clean dust from the condenser surface through airflow. However, existing equipment lacks a dedicated dust-cleaning performance testing module, requiring manual configuration of impurities and simulation of dust accumulation conditions. This cumbersome process cannot quantify the dust-cleaning effect, preventing the effective verification of the fan's cleaning capabilities. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned difficulties and provide a test device for the performance of automotive air conditioning fans.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: A performance testing device for an automotive air conditioning fan includes a main body, within which is an automotive condenser and an air compressor body connected to the condenser. The air compressor body is equipped with a temperature detector capable of detecting the temperature of the automotive condenser. The main body includes a frame with a partition inside. The automotive condenser is inserted into the partition. A through slot is provided on the main frame, into which a feeding mechanism located on one side of the automotive condenser is inserted. A fan body is inserted into the feeding mechanism. A cover plate is correspondingly provided at the top of the main frame. A wind speed detection device is located at the bottom of the cover plate on the other side of the partition. The wind speed detection device can detect the wind speed of the air blown by the fan body after passing through the automotive condenser. Ventilation filter side plates for ventilation and blocking obstructions are correspondingly provided at both ends of the main frame. A slag collection box is inserted at the bottom of the main frame on one side of the ventilation filter side plate. A recycling mechanism located within the main frame is provided between the two ventilation filter side plates.

[0006] As an improvement, the ventilation filter side plate includes a side plate body located at the end of the main frame. An extension block is provided on the side plate body, and the extension block and the side plate body are provided with a contour groove. Ventilation ports are provided at both ends of the contour groove. A hollow tube driven by a motor is provided in the contour groove. Several filter plates and slag leakage grooves are alternately arranged on the hollow tube. A slag return channel is provided at the bottom of the contour groove. A windproof cover is provided on the side plate body at the outlet of the slag return channel. The blockage slag discharged from the slag return channel falls into the slag collection box.

[0007] As an improvement, the motor shaft driving the hollow tube is equipped with a drive key, one end of the hollow tube is equipped with a keyway for inserting the drive key, the motor shaft is fitted with a spring two whose end abuts against the hollow tube, the end of the spring two is fixedly connected to the shaft, a fixing block is fixedly connected to the extension block, a fixing rod is fixedly connected to the fixing block for inserting the hollow tube, a one-way toothed groove two is fixedly connected to the outside of the fixing rod, and the other end of the hollow tube is equipped with a one-way toothed groove one that mates with the one-way toothed groove two.

[0008] As an improvement, when the hollow tube rotates, the teeth on the one-way tooth groove one alternately engage with the teeth and grooves on the one-way tooth groove two. The teeth on the one-way tooth groove one abut against the teeth on the one-way tooth groove two and the grooves are inserted into each other. At this time, the hollow tube vibrates along the axis under the cooperation of the one-way tooth groove two and the one-way tooth groove one, so as to shake off the filter plate blockage slag and fall into the slag return channel through the slag leakage groove.

[0009] As an improvement, the feeding mechanism includes an insert plate that is inserted into the through slot. The insert plate is provided with placement slots located inside and outside the main frame. The fan body is inserted into the placement slot. A worm gear driven by a motor is provided below the insert plate. A worm wheel is meshed on the worm gear. Side plates are provided at both ends of the insert plate and a rack that meshes with the worm wheel is provided at the bottom. Several clamping parts that can press the fan body are provided on the insert plate.

[0010] As an improvement, the main frame is provided with a back basket that fits into the insert plate. The top of the back basket is provided with a pressure plate. The insert plate is provided with a slot. The partition is provided with a pressure plate. The clamping component includes an insert rod located in the slot. The two ends of the insert rod are respectively provided with a pressure block and a protrusion. The insert rod is covered with a spring located between the protrusion and the inner wall of the slot.

[0011] As an improvement, the main frame is equipped with a bracket that can support the air compressor body. The bracket and the bottom of the partition are suspended. The recycling mechanism includes a screw driven by a motor and correspondingly provided. The screw is threaded with screw blocks. A connecting plate is connected between two screw blocks. The bottom of the connecting plate is equipped with a scraper that is slidably connected to the main frame.

[0012] As an improvement, the main frame is provided with a slot, the slag collection box includes a box body inserted into the slot, the box body has a trapezoidal slag guide block in the bearing chamber, the end of the box body is provided with an end cap, a baffle is rotatably provided on the box body, the top of the slag guide block is provided with a magnetic block that can fix the baffle, and the end of the baffle is provided with a handle.

[0013] As an improvement, the wind detection device includes several vertical plates located at the bottom of the cover plate. The vertical plates closer to the car condenser are shorter than those farther away from the car condenser, and an anemometer is installed at the bottom of the vertical plates.

[0014] The advantages of this invention compared to the prior art are as follows: 1. This device improves test reliability through precise operating condition simulation and stable positioning: the air compressor delivers compressed air to the car condenser, replicating the actual working environment of the car air conditioner, while a temperature detector monitors the condenser temperature in real time to ensure stable test conditions. Simultaneously, anemometers on vertical plates of varying lengths in the wind force detection device collect multi-point wind speed data after the fan blows across the condenser, comprehensively reflecting the fan's cooling performance and solving the problem of incomplete data from traditional single-point testing.

[0015] 2. This device ensures equipment cleanliness through automated recycling and self-cleaning structures: the filter plates on the ventilation and filtration side panels intercept impurities in the air; a motor drives the hollow tube to rotate, and the one-way toothed grooves one and two engage to cause the hollow tube to vibrate along its axis, dislodging impurities into the slag collection box; the screw of the recycling mechanism drives a scraper to slide, scraping impurities scattered at the bottom of the equipment into the slag collection box. The slag collection box facilitates the reuse of impurities, eliminating the need for frequent manual cleaning throughout the process, maintaining a clean testing environment, and preventing impurities from affecting detection accuracy.

[0016] 3. This device features an integrated design for dust removal testing: Impurities recovered during testing are stored in a slag collection box. During the dust removal test, the box is vertically inserted into the device, causing impurities to fall and be drawn by the fan onto the surface of the automotive condenser, simulating condenser dust accumulation. The fan body is then reversed to activate the dust removal mode, and an anemometer collects wind speed data from multiple points. By comparing the wind speed changes before and after dust accumulation, the fan's dust removal performance can be accurately evaluated. This closed-loop design of "impurity recovery - simulated dust accumulation - dust removal testing" eliminates the need for additional impurity configuration, is easy to operate, and provides a realistic testing scenario, filling a gap in traditional equipment dust removal performance testing.

[0017] 4. This device improves overall efficiency through multi-structure collaboration: the dual-placement slot design of the feeding mechanism allows for the simultaneous loading and unloading of one fan while another is being tested, eliminating the need for downtime; the self-cleaning of the ventilation filter side panels and the automated cleaning of the recycling mechanism avoid time-consuming manual cleaning. The entire testing process achieves continuous operation of "cooling test - dust removal test - equipment self-cleaning," significantly improving testing efficiency compared to traditional equipment and adapting to the performance testing needs of batch fans.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings.

[0033] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 10 As shown: A performance testing device for an automotive air conditioning fan includes a main body 1. The main body 1 houses an automotive condenser 3 and an air compressor body 2 connected to the automotive condenser 3. The air compressor body 2 is equipped with a temperature detector 201 capable of detecting the temperature of the automotive condenser 3. The main body 1 includes a main frame 101, within which a partition 102 is provided. The automotive condenser 3 is inserted into the partition 102. A through groove 106 is provided on the main frame 101, and a feeding mechanism 4 located on one side of the automotive condenser 3 is inserted into the through groove 106. The fan body 5 is inserted into the top, and a cover plate 105 is provided on the top of the main frame 101. A wind force detection device 6 is provided at the bottom of the cover plate 105 on the other side of the partition 102. The wind force detection device 6 can detect the wind speed of the air blown out by the fan body 5 after passing through the car condenser 3. Ventilation filter side plates 7 that can ventilate and intercept blockages are provided at both ends of the main frame 101. A slag collection box 8 located on one side of the ventilation filter side plate 7 is inserted into the bottom of the main frame 101. A recycling mechanism 9 located inside the main frame 101 is provided between the two ventilation filter side plates 7.

[0034] The working principle of this invention is as follows: This device uses "simulated working conditions - precise detection - cleaning and recycling" as its core logic to complete the temperature test and dust removal test of the fan body 5. In this invention, the fan body 5 is fixed by the feeding mechanism 4, the air compressor body 2 and the car condenser 3 simulate the working environment of the car air conditioning, the wind speed detection device 6 performs multi-point detection of the wind speed after the fan blows through the condenser, and the temperature detector 201 monitors the temperature of the condenser. The ventilation filter side plate 7 not only realizes the ventilation function, but also intercepts impurities and automatically shakes them off. The recycling mechanism 9 cleans the residue inside the equipment. Finally, the impurities from the ventilation filter side plate 7 and the recycling mechanism 9 are collected by the slag collection box 8. In the subsequent dust removal test of the fan body 5, the staff manually attaches the impurities in the slag collection box 8 to the car condenser 3, and at the same time reverses the fan body 5 to start the dust removal work. The wind speed detection device 6 performs multi-point detection of the wind speed after the fan blows through the condenser. After that, the staff can complete the dust removal test of the fan body 5 by comparing the wind speed before and after the impurities are attached. This realizes the automated closed loop of fan performance testing, equipment self-cleaning and impurity recycling and reuse.

[0035] During the cooling test of the fan body 5, after the air compressor body 2 is started, it can deliver compressed air to the car condenser 3 through the pipeline, simulating the airflow circulation of the car's air conditioning system. The car condenser 3 operates according to preset parameters, and the temperature detector 201 collects the surface temperature of the condenser in real time to ensure that the test conditions are consistent with the actual use scenario of the car. At this time, the temperature test of the fan body 5 can begin. When the fan body 5 starts, the air passes through the car condenser 3 and is discharged from the fan body 5, that is, the airflow direction is from the car condenser 3 to the fan body 5, completing the simulation of the working conditions. The temperature detector 201 can ensure the stability of the working condition parameters, forming a complete performance test link.

[0036] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 6 Appendix Figure 7 As shown: The ventilation and filter side plate 7 includes a side plate body 701 located at the end of the main frame 101. An extension block is provided on the side plate body 701, and the extension block and the side plate body 701 are provided with a contour groove 702. Ventilation ports 703 are provided at both ends of the contour groove 702. A hollow tube 705 driven by a motor is provided in the contour groove 702. Several filter plates 706 and slag leakage grooves 707 are alternately provided on the hollow tube 705. A slag return channel 704 is provided at the bottom of the contour groove 702. A windproof cover 715 is provided on the side plate body 701 at the outlet of the slag return channel 704. The blockage slag discharged from the slag return channel 704 falls into the slag collection box 8.

[0037] A drive key 709 is provided on the shaft of the motor that drives the hollow tube 705. One end of the hollow tube 705 is provided with a keyway 708 that is inserted into the drive key 709. The shaft of the motor is fitted with a spring 710 whose end abuts against the hollow tube 705. The end of the spring 710 is fixedly connected to the shaft. A fixing block 712 is fixedly connected to the extension block. A fixing rod 713 that is inserted into the hollow tube 705 is fixedly connected to the fixing block 712. A one-way toothed groove 714 is fixedly connected to the outside of the fixing rod 713. The other end of the hollow tube 705 is provided with a one-way toothed groove 711 that mates with the one-way toothed groove 714. When the hollow tube 705 rotates, the teeth on the one-way toothed groove 711 alternately engage with the teeth and grooves on the one-way toothed groove 714. The teeth on the one-way toothed groove 711 abut against the teeth on the one-way toothed groove 714 and the grooves are inserted into each other. At this time, the hollow tube 705 vibrates along the axis under the engagement of the one-way toothed groove 714 and the one-way toothed groove 711, so as to shake off the slag blocking the filter plate 706 and drop it into the slag return channel 704 through the slag leakage channel 707.

[0038] Working principle of ventilation filter side plate 7: When the present invention is performing dust removal, outside air enters through the ventilation port 703 on one side, and the filter plate 706 intercepts impurities in the air. When the fan body 5 is started, it can blow out the impurities attached to the car condenser 3, and the air is output from the ventilation port 703 on the other side. At this time, the filter plate 706 on the other side intercepts impurities in the air. That is, when the present invention is working, the motor needs to be started to drive the hollow tube 705 to rotate. Because the teeth of the one-way toothed groove 711 in the present invention can alternately interact with the teeth of the one-way toothed groove 714, The groove is engaged, and under the elastic force of spring 710, the hollow tube 705 can continuously vibrate along the axis. At this time, the vibrating filter plate 706 can shake off the slag that is attached to and clogging it. The shaken-off impurities will slide along the filter plate 706 to the slag leakage groove 707 or the slag return channel 704. The impurities passing through the slag leakage groove 707 will still fall into the slag return channel 704 and be discharged from the outlet of the slag return channel 704. The windproof cover 715 can prevent the airflow generated when the fan body 5 starts from interfering with the falling of impurities, and finally the impurities fall into the slag collection box 8. The ventilation filter side plate 7 in this invention can realize the ventilation of the equipment and the interception of impurities. And through vibration, it can automatically clean the blockage on the filter plate 706, ensuring smooth ventilation and the cleaning and recycling of impurities, greatly reducing the frequency of manual cleaning. The filtration and self-cleaning are linked, and impurities can be cleaned without stopping the machine, ensuring continuous operation of the equipment. This invention uses a one-way toothed groove and spring to make the vibration and rotation actions smoothly connected, and no additional power source is required.

[0039] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 10 As shown: The feeding mechanism 4 includes an insert plate 401 that is inserted into the through slot 106. The insert plate 401 is provided with a placement slot 402 located inside and outside the main frame 101. The fan body 5 is inserted into the placement slot 402. The insert plate 401 is provided with a worm gear 404 driven by a motor. A worm wheel 405 is meshed on the worm gear 404. The insert plate 401 is provided with side plates 410 at both ends and a rack 403 that meshes with the worm wheel 405 at the bottom. The insert plate 401 is provided with several clamping parts that can press the fan body 5.

[0040] The main frame 101 has a back basket 107 that fits into the insert plate 401. The top of the back basket 107 has a pressure plate 108. The insert plate 401 has a slot on one side of the placement groove 402. The partition plate 102 has a pressure plate 104. The clamping component includes an insert rod 406 located in the slot. The two ends of the insert rod 406 are respectively provided with a pressure block 407 and a protrusion 408. The insert rod 406 is covered with a spring 409 located between the protrusion 408 and the inner wall of the slot.

[0041] Working principle of the feeding mechanism 4: Since two fan bodies 5 can be placed and installed simultaneously on the insertion plate 401, when one fan body 5 is undergoing performance testing, the other fan body 5 can be removed and reinstalled to install the fan body 5 to be tested later. Specifically, during testing, the motor drives the worm gear 404 to rotate, which in turn drives the worm wheel 405 to rotate. Through the rack 403, the insertion plate 401 extends out of the device from the through slot 106, inserting the fan body 5 into the placement slot 402. In this invention, the insertion plate 401 is equipped with an electrical connection socket. When the fan body 5 is inserted into the placement slot 402, it needs to be connected to the electrical connection socket on the insertion plate 401. The motor drives the worm gear 404 to rotate, which in turn drives the worm wheel 405 to rotate. Through the rack 403, the fan body 5 is pulled... The insert plate 401 retracts into the equipment, precisely aligning the fan body 5 with the automotive condenser 3. As the insert plate 401 retracts, the back frame 107 and the insert plate 401 are in contact, allowing the back frame 107 to press against the protrusion 408, causing the protrusion 408 to retract into the slot. The protrusion 408 then compresses the spring 409, and the protrusion 408, through the insert rod 406, presses the pressure block 407 firmly against the fan body 5, preventing shaking during testing. After testing, the motor of the feeding mechanism 4 is reversed, and the insert plate 401 extends from the other side of the main frame 101. The spring 409 then resets, resetting the pressure component. Finally, the fan body 5 is removed and reinstalled for subsequent tests. The feeding mechanism 4 enables rapid feeding, precise positioning, and stable fixing of the fan body 5, ensuring consistent posture during testing and improving the accuracy of the test data.

[0042] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 6 Appendix Figure 7 Appendix Figure 8Appendix Figure 10 Appendix Figure 11 Appendix Figure 12 Appendix Figure 13 As shown: The main frame 101 is provided with a bracket 103 that can support the air compressor body 2. The bracket 103 and the bottom of the partition 102 are suspended. The recycling mechanism 9 includes a screw 901 driven by a motor and correspondingly provided. The screw 901 is threaded with screw blocks 902. A connecting plate 903 is connected between two screw blocks 902. The bottom of the connecting plate 903 is provided with a scraper 904 whose bottom end is slidably connected to the main frame 101.

[0043] The main frame 101 has a slot 109. The slag collection box 8 includes a box body 801 inserted into the slot 109. The bearing chamber 802 of the box body 801 has a trapezoidal slag guide block 803. The end of the box body 801 has an end cap 806. A baffle 805 is rotatably mounted on the box body 801. The top of the slag guide block 803 has a magnetic block 804 that can fix the baffle 805. The end of the baffle 805 has a handle 807.

[0044] In this invention, the main frame 101 provides the foundation for the installation and support of all functional components. The partition 102 divides the interior into a test area and a detection area. The automotive condenser 3 is inserted into and fixed on the partition 102. The bracket 103 suspends and supports the air compressor body 2, facilitating the operation of the recycling mechanism 9. The back basket 107 and the pressure plate 108 work together with the feeding mechanism 4 to fix the fan body 5, ensuring the fan position is stable during testing. The cover plate 105 closes the top of the equipment to reduce external airflow interference. The through slot 106 allows the feeding mechanism 4 to enter and exit, and the slot 109 allows the slag collection box 8 to be inserted. The suspended bracket 103 and the positioning structure ensure accurate installation of the components.

[0045] like Figure 1 As shown in Figures 2 / 3 / 10, an inlet is provided on the main frame 101 at the location of the automotive condenser 3. The inner wall of the inlet is provided with a sealing plate pressed by a spring sheet. The slag collection box 8 in this invention is as follows: Figure 11 The image shows the horizontal position. When it is necessary to attach impurities to the car condenser 3, the slag collection box 8 is pulled out from below, and the handle 807 is rotated so that the baffle 805 is attracted by the magnetic block 804. Then, the slag collection box 8 is changed from horizontal to vertical and reinserted into the main frame 101 through the socket. Then, the handle 807 is reversed so that the baffle 805 is separated from the magnetic block 804. At this time, the impurities in the slag collection box 8 fall off and are sucked into the car condenser 3 when the fan body 5 is started.

[0046] In this invention, impurities falling from the ventilation filter side plate 7 fall into the bearing chamber 802 of the slag collection box 8 via the slag return channel 704. The guide block 803 guides the impurities to gather in the chamber and subsequently discharge them. A motor drives the screw 901 to rotate, causing the screw block 902 and connecting plate 903 to move. The scraper 904 slides along the bottom of the main frame 101, scraping the impurities into the slag collection box 8. The impurities intercepted by the ventilation filter side plate 7 and those scattered inside the equipment are collected, and the internal cleaning of the equipment is achieved through the recycling mechanism 9, maintaining a clean testing environment. The impurity collection in this invention is relatively concentrated, and cleaning and recycling are relatively convenient. The recycling mechanism 9 automatically cleans the bottom of the equipment, preventing impurity accumulation from affecting testing accuracy.

[0047] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 9 As shown: The wind detection device 6 includes several vertical plates 601 located at the bottom of the cover plate 105. The vertical plates 601 closer to the car condenser are shorter than the vertical plates 601 farther away from the car condenser. An anemometer 602 is provided at the bottom of the vertical plates 601.

[0048] The air blown out by the fan body 5 passes through the car condenser 3 and diffuses towards the wind force detection area. Due to the varying lengths of the vertical plates 601, the anemometers 602 are distributed at different heights and horizontal positions, allowing for the collection of wind speed data from multiple points. The anemometers 602 convert the collected wind speed signals into electrical signals, which are then transmitted to the control system to calculate performance parameters such as fan wind force intensity and wind speed uniformity, thus completing the dust removal performance test. Multi-point collection of wind speed data after the fan passes through the condenser provides a comprehensive evaluation of the fan's wind force performance and airflow uniformity. This multi-point detection design provides a more comprehensive reflection of fan performance than single-point detection, significantly improving detection accuracy. The differentiated length design of the vertical plates adapts to the airflow diffusion trajectory, ensuring the accuracy and validity of the collected data. The anemometers respond quickly, providing real-time feedback on the fan's dynamic performance.

[0049] When implementing the automotive air conditioning fan performance testing equipment, the automotive condenser 3 is first inserted and fixed on the partition 102 of the main frame 101. The air compressor body 2 is placed on the bracket 103 and connected to the automotive condenser 3. The temperature detector 201 is installed on the air compressor body 2 to monitor the condenser temperature in real time. The slag collection box 8 is inserted into the bottom of the main frame 101 through the slot 109 to ensure that it is located below the slag return channel 704 of the ventilation filter side plate 7.

[0050] Start the feeding mechanism 4: The motor drives the worm gear 404 to rotate, which drives the worm wheel 405 to mesh with the rack 403, so that the insert plate 401 extends out from the through slot 106, inserts the fan body 5 to be tested into the placement slot 402 and connects it with the electrical connection socket on the insert plate 401. The motor reverses and pulls the insert plate 401 back into the equipment. The back basket 107 squeezes the protrusion 408, the spring 409 is compressed, and the insert rod 406 drives the pressure block 407 to press the fan body 5 tightly to prevent shaking during the test.

[0051] The equipment was then started for a cooling performance test: the air compressor body 2 delivered compressed air to the car condenser 3 to simulate air conditioning conditions, the fan body 5 started, and the air diffused through the car condenser 3 to the wind force detection device 6, while the temperature detector 201 recorded the condenser temperature simultaneously. During the test, the motor of the ventilation filter side plate 7 drove the hollow tube 705 to rotate. The one-way toothed groove 711 and the one-way toothed groove 714 cooperated, and under the action of the spring 710, the hollow tube 705 vibrated along the axis. The impurities intercepted by the filter plate 706 were shaken off and fell into the slag collection box 8 through the slag leakage groove 707 and the slag return channel 704. At the same time, the recovery mechanism 9 was started, the motor drove the screw 901 to rotate, and the screw block 902 drove the connecting plate 903 and the scraper 904 to slide, scraping the impurities scattered at the bottom of the main frame 101 into the slag collection box 8.

[0052] After the cooling performance test is completed, the dust removal performance test is performed: Remove the slag collection box 8, rotate the handle 807 to disengage the baffle 805 from the magnetic block 804, insert the slag collection box 8 vertically through the socket, and the impurities will fall and be sucked onto the car condenser 3 by the fan. Reverse the fan body 5 to activate the dust removal mode. The anemometer 602 on the vertical plates 601 of different lengths at the bottom of the cover 105 collects wind speed data at multiple points, thus completing the fan dust removal performance evaluation. After the test, the motor drives the insert plate 401 to extend, the spring 409 returns to its original position, the fan body 5 is removed, the impurities in the slag collection box 8 are cleaned, and the equipment is turned off.
