Description

Technical Field

[0001] The present invention relates to the technical field of motor heat dissipation equipment, and in particular to a motor protection heat dissipation equipment and a heat dissipation method thereof. Background Art

[0002] With the advancement of science and technology, large and complex integrated motor equipment is increasingly used in agriculture, industry or engineering technology. Motor equipment will generate more heat during operation. If the heat is not dissipated in time, it will affect the service life of the equipment.

[0003] When the motor works in a dry environment such as a desert, there is usually a lot of sand and dust in this working environment. While the fan is dissipating heat, it also comes into contact with fine particles in the air, causing particles to accumulate on the outer wall of the fan blades, increasing the load on the fan blades and affecting the exhaust function. To address the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a motor protection and heat dissipation device, including an air inlet mechanism and a device housing, a mounting pipe is connected through the side wall of the device housing, and a rotating cylinder is rotatably connected to the inner wall of the device housing;

[0005] The cooling mechanism includes a filter screen fixedly connected to the inner wall of the mounting tube, a power motor fixedly connected to the side wall of the filter screen, and an output shaft of the power motor fixedly connected to the mounting plate;

[0006] The control mechanism includes a fixed bracket fixedly connected to the side wall of the equipment housing, a miscellaneous material collection pipe is connected through the side wall of the fixed bracket, a rotating column is rotatably connected to the outer wall of the mounting plate, a sliding frame is fixedly connected to the end of the rotating column away from the mounting plate, and a plurality of sealing slides are slidably connected to the outer wall of the sliding frame.

[0007] Preferably, the air inlet mechanism also includes an air inlet opened on the side wall of the rotating cylinder, an air guide plate is fixedly connected to the top of the rotating cylinder, and a filter plate is fixedly connected to the inner wall of the equipment casing. The above-mentioned equipment is installed in a desert location with a faster wind speed, and an air guide plate is arranged inside the equipment. When a faster wind speed is generated outside, the air guide plate is swung by the wind force, so that the rotating cylinder and the air inlet rotate synchronously, and the air guide plate is parallel to the direction of the wind flow, so that the air inlet is always on the leeward side, so that the equipment can minimize the dust content when collecting air from the external environment, and as the rotating cylinder rotates, the cleaning rack will scratch the outer wall of the filter plate to remove impurities stuck to the outer wall of the filter plate, thereby ensuring that the equipment can continuously and effectively cool the motor.

[0008] Preferably, the air inlet mechanism further comprises a cleaning frame fixedly connected to the inner wall of the rotating cylinder, the bottom of the cleaning frame is rotatably connected to the top of the filter plate, and a partition is fixedly connected to the side wall of the cleaning frame.

[0009] Preferably, the cooling mechanism also includes an impurity outlet connected through the bottom of the mounting tube, a plurality of sliding blades are fixedly connected to the side wall of the mounting plate, a counterweight is slidably connected to the outer wall of the sliding blade, a metal chain is fixedly connected to the side wall of the counterweight, a collecting wheel is rotatably connected to the inner wall of the mounting plate, a spring is fixedly connected to the bottom of the collecting wheel, the top of the impurity outlet is connected through the outer wall of the miscellaneous material collection tube, and a cooling mechanism is provided inside the equipment by utilizing the characteristic that centrifugal force is generated during the rotation of the objects. Before using the equipment, the mounting tube is installed outside the box to be cooled, and the power supply of the power motor is turned on. The power motor drives the sliding blades through the mounting plate to transmit the air inside the equipment casing to the inside of the mounting tube. In this process, the counterweight will diffuse to the surroundings along the outer wall of the sliding blade under the centrifugal force, and the annular counterweight will scrape off the impurities remaining on the outer wall of the sliding blade during the sliding process, thereby ensuring the normal operation of the equipment before the sliding blade is used, removing impurities on the outer wall of the sliding blade, and preventing impurities from affecting the subsequent cooling efficiency of the motor.

[0010] Preferably, the cooling mechanism also includes a roller 1 rotatably connected to the inner wall of the through hole of the mounting plate, one end of the metal chain away from the counterweight block is fixedly connected to the side wall of the collecting wheel, one end of the sliding fan blade away from the mounting plate is fixedly connected to a slide rail, one end of the slide rail away from the sliding fan blade is fixedly connected to a rotating ring, a sliding rod is slidably connected to the inner wall of the rotating ring, and a roller 2 is rotatably connected to the outer wall of the sliding rod, and one end of the sliding rod away from the roller 2 is fixedly connected to a compression spring. During the outward movement of the counterweight block, the counterweight block will drag the metal chain to move outward synchronously. During this process, the outward movement of the metal chain will generate a pulling force on the collecting wheel, and the lengths of several metal chains are equal. The extension length of the metal chain is controlled by the rotation angle of the collecting wheel, and the lateral movement distance of the counterweight block is indirectly controlled to ensure that the center of gravity of the sliding fan blade remains unchanged when the sliding fan blade is cleaned. Through the application of the above-mentioned components, impurities stuck to the outer wall of the sliding fan blade can be effectively removed, thereby ensuring the stability of the equipment during use.

[0011] Preferably, the control mechanism also includes a sliding square rod fixedly connected to the end of the sealing slide away from the sliding frame, the end of the sliding square rod away from the sealing slide is fixedly connected to a compressed arc plate, the outer wall of the sliding square rod is slidably connected to the inner wall of the through hole of the fixed bracket, and the inner wall of the compressed arc plate is slidably connected to a telescopic slide. Utilizing the above-mentioned characteristic of outward movement due to centrifugal force, a sliding rod is arranged inside the device. When the counterweight block moves outward and contacts the side of the sliding rod, the sliding rod is pressed to move outward along the inner wall of the rotating ring, forcing the second roller to contact the compressed arc plate. In this process, the compressed arc plate and the telescopic slide form a retractable and expandable circle, presenting a shape like Fig. 9In the state, the second roller contacts the inner wall of the circle and forces the circle to expand. The expanded circle will push the sliding square rod to expand around along the through hole of the fixed bracket. At this time, the sliding square rod will push the sealing slide to spread around, so that different gaps appear between the sealing slides, such as Fig.10 In the state shown, the air on the inner wall of the sealing slide enters the motor case to be cooled through the gap. Through the application of the above components, the external air enters the case through several gaps, the flow rate is increased, and the equipment can improve the efficient cooling of the motor case.

[0012] Preferably, the control mechanism also includes a rotating shield plate rotatably connected to the inner wall of the through hole of the fixed bracket, an L-shaped rod is fixedly connected to the inner wall of the sealing slide, one end of the L-shaped rod away from the sealing slide is rotatably connected to the side wall of the rotating shield plate, and a spring is fixedly connected to the side wall of the L-shaped rod. Utilizing the characteristic that the sealing slide plate expands outward during operation, a rotating shield plate is arranged inside the device. When the sealing slide plate does not expand outward, the sealing slide plate and the L-shaped rod are in a state as shown in the figure below under the action of the internal spring. Fig. 9 In the state shown, a large gap is formed between the rotating baffle and the fixed bracket, and in this process, since a slide rail is provided inside the equipment, when the counterweight block has not entered the slide rail, the sealing slide plate has not been squeezed by the sliding square rod, and several sealing slide plates are in a closed state. When the counterweight block cleans the surface of the sliding fan blade, the removed dust mixes with the air and acts on the inner wall of the sealing slide plate, and generates a reverse flow, which enters the interior of the debris collection pipe from the gap between the rotating baffle and the fixed bracket, and is finally discharged from the impurity outlet. Through the application of the above-mentioned components, the total amount of dust entering the interior of the equipment can be effectively reduced, and dust can be prevented from entering the motor case and accumulating on the outer wall of the motor, affecting the heat dissipation effect of the motor.

[0013] A heat dissipation method for a motor protection heat dissipation device comprises the following steps:

[0014] S1: Before using the equipment, install the installation pipe outside the box to be cooled, and turn on the power of the power motor. The power motor drives the sliding fan blades through the installation plate to transfer the air inside the equipment casing to the inside of the installation pipe;

[0015] S2: The counterweight block will spread out along the outer wall of the sliding blade due to the centrifugal force, and the annular counterweight block will scrape off the impurities remaining on the outer wall of the sliding blade during the sliding process;

[0016] S3: During the outward movement of the counterweight, the counterweight will drag the metal chain to move outward synchronously. During this process, the outward movement of the metal chain will generate a pulling force on the collecting wheel, making the lengths of several metal chains equal.

[0017] The present invention has the following beneficial effects:

[0018] (1) The present invention utilizes the characteristic that centrifugal force is generated during the rotation of an object, and a cooling mechanism is provided inside the device. Before using the device, the mounting tube is installed outside the box to be cooled, and the power supply of the power motor is turned on. The power motor drives the sliding blades through the mounting plate to transmit the air inside the device casing to the inside of the mounting tube. During this process, the counterweight block is subjected to the centrifugal force and diffuses to the surroundings along the outer wall of the sliding blade, and the annular counterweight block will scrape off the impurities remaining on the outer wall of the sliding blade during the sliding process, thereby ensuring the normal operation of the device before the sliding blade is used; in addition, during the outward movement of the counterweight block, the counterweight block will drag the metal chain to move outward synchronously. During this process, the outward movement of the metal chain will generate a pulling force on the collection wheel, and the lengths of several metal chains are equal. The extension length of the metal chain is controlled by the rotation angle of the collecting wheel, and the lateral movement distance of the counterweight block is indirectly controlled, thereby ensuring that the center of gravity of the sliding blade remains unchanged when the sliding blade is cleaned. Through the application of the above-mentioned components, impurities adhering to the outer wall of the sliding blade can be effectively removed, thereby ensuring the stability of the device during use.

[0019] (2) The present invention utilizes the characteristic that the counterweight block moves outward due to centrifugal force, and a sliding rod is provided inside the device. When the counterweight block moves outward and contacts the side of the sliding rod, the sliding rod is pressed and moves outward along the inner wall of the rotating ring, forcing the second roller to contact the compressed arc plate. In this process, the compressed arc plate and the telescopic slide plate form a circle that can be retracted and expanded, presenting a Fig. 9 In the state, the second roller contacts the inner wall of the circle and forces the circle to expand. The expanded circle will push the sliding square rod to expand around along the through hole of the fixed bracket. At this time, the sliding square rod will push the sealing slide to spread around, so that different gaps appear between the sealing slides, such as Fig.10 In the state shown, the air on the inner wall of the sealing slide enters the box to be cooled through the gap. Through the application of the above components, the external air enters the box through several gaps, the flow rate is increased, and the cooling efficiency of the equipment on the box is improved.

[0020] (3) The present invention utilizes the characteristic that the sealing slide plate expands outwards during operation, and a rotating shield is arranged inside the device. When the sealing slide plate does not expand outwards, the sealing slide plate and the L-shaped rod are in the form of a rotating shield under the action of the internal spring. Fig. 9In the state shown, a large gap is formed between the rotating baffle and the fixed bracket, and in this process, since a slide rail is provided inside the equipment, when the counterweight block has not entered the slide rail, the sealing slide plate has not been squeezed by the sliding square rod, and several sealing slide plates are in a closed state. When the counterweight block cleans the surface of the sliding fan blade, the removed dust mixes with the air and acts on the inner wall of the sealing slide plate, and generates a reverse flow, which enters the interior of the debris collection pipe from the gap between the rotating baffle and the fixed bracket, and is finally discharged from the impurity outlet. Through the application of the above-mentioned components, the total amount of dust entering the interior of the equipment can be effectively reduced.

[0021] (4) The present invention utilizes the above-mentioned device to be installed in a desert location with a relatively fast wind speed. An air guide plate is arranged inside the device. When a relatively fast wind speed is generated outside, the air guide plate is swung by the wind force, causing the rotating cylinder and the air inlet to rotate synchronously. The air guide plate is parallel to the direction of the wind flow, so that the air inlet is always on the leeward side, so that when the device collects air from the external environment, the content of sand and dust is minimized. As the rotating cylinder rotates, the cleaning frame will scrape the outer wall of the filter plate to remove impurities stuck to the outer wall of the filter plate. In addition, when the sealing slide plate expands outward, the sealing slide plate drives the rotating shield plate to be tightly attached to the inner wall of the fixed bracket through the L-shaped rod, so that the fixed bracket is in a closed state, so as to prevent dust particles on the inner wall of the miscellaneous material collection pipe from being brought into the cooling box when the device transmits gas through the sealing slide plate, thereby affecting the dust prevention effect of the device.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The control mechanism 3 includes a fixed bracket 301 fixedly connected to the side wall of the equipment housing 101, a miscellaneous material collection pipe 302 is connected through the side wall of the fixed bracket 301, a rotating column 303 is rotatably connected to the outer wall of the mounting plate 203, a sliding frame 304 is fixedly connected to the end of the rotating column 303 away from the mounting plate 203, and a plurality of sealing slides 305 are slidably connected to the outer wall of the sliding frame 304.

[0040] The air inlet mechanism 1 also includes an air inlet 104 opened on the side wall of the rotating cylinder 103, an air guide plate 105 is fixedly connected to the top of the rotating cylinder 103, and a filter plate 106 is fixedly connected to the inner wall of the device housing 101. The above-mentioned device is installed in a desert location with a faster wind speed, and an air guide plate 105 is arranged inside the device. When a faster wind speed is generated outside, the air guide plate 105 swings due to the wind force, so that the rotating cylinder 103 and the air inlet 104 rotate synchronously, and the air guide plate 105 is parallel to the direction of the wind flow, so that the air inlet 104 is always on the leeward side, so that the device can minimize the content of sand and dust when collecting air from the external environment, and as the rotating cylinder 103 rotates, the cleaning frame 107 will scrape the outer wall of the filter plate 106 to remove impurities stuck to the outer wall of the filter plate 106, so as to ensure that the device can continuously and effectively cool the motor.

[0041] The air inlet mechanism 1 further comprises a cleaning frame 107 fixedly connected to the inner wall of the rotating cylinder 103 , the bottom of the cleaning frame 107 is rotatably connected to the top of the filter plate 106 , and a partition plate 108 is fixedly connected to the side wall of the cleaning frame 107 .

[0042] For example 2, please refer to Figure 4 - Fig.11The present invention is a motor protection and heat dissipation device. On the basis of the first embodiment, the cooling mechanism 2 also includes an impurity outlet 214 connected to the bottom of the mounting tube 102, a plurality of sliding blades 204 are fixedly connected to the side wall of the mounting plate 203, a counterweight block 205 is slidably connected to the outer wall of the sliding blade 204, a metal chain 206 is fixedly connected to the side wall of the counterweight block 205, a collecting wheel 207 is rotatably connected to the inner wall of the mounting plate 203, a spring is fixedly connected to the bottom of the collecting wheel 207, the top of the impurity outlet 214 is connected to the outer wall of the miscellaneous material collection tube 302, and the centrifugal force generated during the rotation of the object is used to set the impurity outlet 214 inside the device. There is a cooling mechanism 2. Before using the equipment, install the mounting tube 102 outside the box to be cooled, and turn on the power supply of the power motor 202. The power motor 202 drives the sliding blades 204 through the mounting plate 203 to transmit the air inside the equipment housing 101 to the inside of the mounting tube 102. During this process, the counterweight block 205 will diffuse around along the outer wall of the sliding blade 204 under the centrifugal force, and the annular counterweight block 205 will scrape off the impurities remaining on the outer wall of the sliding blade 204 during the sliding process, so as to ensure the normal operation of the equipment before the sliding blade 204 is used, remove the impurities on the outer wall of the sliding blade 204, and prevent the impurities from affecting the subsequent cooling efficiency of the motor.

[0043] The cooling mechanism 2 also includes a roller 1 208 rotatably connected to the inner wall of the through hole of the mounting plate 203, an end of the metal chain 206 away from the counterweight 205 is fixedly connected to the side wall of the collecting wheel 207, an end of the sliding blade 204 away from the mounting plate 203 is fixedly connected to a slide rail 209, an end of the slide rail 209 away from the sliding blade 204 is fixedly connected to a rotating ring 210, a sliding rod 211 is slidably connected to the inner wall of the rotating ring 210, a roller 212 is rotatably connected to the outer wall of the sliding rod 211, and an end of the sliding rod 211 away from the roller 212 is fixedly connected to a compression spring 213. During the outward movement of the counterweight 205, the counterweight 205 will drag the metal chain 206 to move outward synchronously. During this process, the outward movement of the metal chain 206 will generate a pulling force on the collecting wheel 207. The lengths of several metal chains 206 are equal. The angle of rotation of the collecting wheel 207 is used to control the outward length of the metal chain 206, and the lateral movement distance of the counterweight 205 is indirectly controlled to ensure that the center of gravity of the sliding blade 204 remains unchanged when the sliding blade 204 is cleaned. Through the application of the above-mentioned components, impurities stuck to the outer wall of the sliding blade 204 can be effectively removed to ensure the stability of the equipment during use.

[0044] The control mechanism 3 also includes a sliding square rod 307 fixedly connected to the end of the sealing slide 305 away from the sliding frame 304, and the end of the sliding square rod 307 away from the sealing slide 305 is fixedly connected to a compressed arc plate 308, the outer wall of the sliding square rod 307 is slidably connected to the inner wall of the through hole of the fixed bracket 301, and the inner wall of the compressed arc plate 308 is slidably connected to a telescopic slide 309. Utilizing the characteristic that the above-mentioned 295 moves outward due to centrifugal force, a sliding rod 211 is arranged inside the device. When the counterweight block 205 moves outward and contacts the side of the sliding rod 211, the sliding rod 211 is pressed and moves outward along the inner wall of the rotating ring 210, forcing the roller 212 to contact the compressed arc plate 308. In this process, the compressed arc plate 308 and the telescopic slide 309 form a retractable and expandable circle, presenting as shown in the figure. Fig. 9 In the state, the roller 212 contacts the inner wall of the circle and forces the circle to expand. The expanded circle will push the sliding square rod 307 to expand around along the through hole of the fixed bracket 301. At this time, the sliding square rod 307 will push the sealing slide plate 305 to spread around, so that different gaps appear between the sealing slide plates 305, such as Fig.10 In the state shown, the air on the inner wall of the sealing slide plate 305 enters the motor box to be cooled through the gap. Through the application of the above-mentioned components, the external air enters the box through several gaps, the flow rate is increased, and the equipment improves the efficient cooling of the motor box.

[0045] The control mechanism 3 also includes a rotating shield plate 311 rotatably connected to the inner wall of the through hole of the fixed bracket 301, an L-shaped rod 310 is fixedly connected to the inner wall of the sealing slide 305, and one end of the L-shaped rod 310 away from the sealing slide 305 is rotatably connected to the side wall of the rotating shield plate 311, and a spring is fixedly connected to the side wall of the L-shaped rod 310. Taking advantage of the characteristic that the sealing slide 305 expands outward during operation, a rotating shield plate 311 is arranged inside the device. When the sealing slide 305 does not expand outward, the sealing slide 305 and the L-shaped rod 310 are in the state of being as shown below under the action of the internal spring. Fig. 9 In the state shown, a large gap is formed between the rotating baffle 311 and the fixed bracket 301. In this process, since a slide rail 209 is provided inside the equipment, when the counterweight 205 has not entered the slide rail 209, the sealing slide 305 has not been squeezed by the sliding square rod 307, and several sealing slides 305 are in a closed state. When the counterweight 205 cleans the surface of the sliding fan blade 204, the removed dust mixes with the air and acts on the inner wall of the sealing slide 305, and generates a reverse flow, which enters the interior of the debris collection pipe 302 from the gap between the rotating baffle 311 and the fixed bracket 301, and is finally discharged from the impurity outlet 214. Through the application of the above-mentioned components, the total amount of dust entering the interior of the equipment can be effectively reduced, and dust can be prevented from entering the motor case and accumulating on the outer wall of the motor, affecting the heat dissipation effect of the motor.

[0046] The cooling method of the cooling device comprises the following steps:

[0047] S1: Before using the device, install the installation tube 102 outside the box to be cooled, and turn on the power of the power motor 202. The power motor 202 drives the sliding blades 204 through the installation plate 203 to transfer the air inside the device housing 101 to the inside of the installation tube 102;

[0048] S2: The counterweight 205 is spread out along the outer wall of the sliding blade 204 by the centrifugal force, and the annular counterweight 205 scrapes off the impurities remaining on the outer wall of the sliding blade 204 during the sliding process;

[0049] S3: During the outward movement of the counterweight 205 , the counterweight 205 will drag the metal chain 206 to move outward synchronously. During this process, the outward movement of the metal chain 206 will generate a pulling force on the collecting wheel 207 , making the lengths of several metal chains 206 equal.

[0050] A specific application of this embodiment is: before using the device, the installation tube 102 is installed outside the motor case to be cooled, and the power supply of the power motor 202 is turned on. The power motor 202 drives the sliding blades 204 through the installation plate 203 to transmit the air inside the device housing 101 to the inside of the installation tube 102. In this process, the counterweight block 205 will diffuse to the surroundings along the outer wall of the sliding blade 204 due to the centrifugal force, and the annular counterweight block 205 will scrape off the impurities remaining on the outer wall of the sliding blade 204 during the sliding process, so as to ensure the normal operation of the device before the sliding blade 204 is used; another During the outward movement of the external counterweight 205, the counterweight 205 will drag the metal chain 206 to move outward synchronously. During this process, the outward movement of the metal chain 206 will generate a pulling force on the collecting wheel 207. The lengths of several metal chains 206 are equal. The angle of rotation of the collecting wheel 207 is used to control the extended length of the metal chain 206, and the lateral movement distance of the counterweight 205 is indirectly controlled to ensure that the center of gravity of the sliding blade 204 remains unchanged when the sliding blade 204 is cleaned. Through the application of the above-mentioned components, impurities stuck to the outer wall of the sliding blade 204 can be effectively removed to ensure the stability of the equipment during use.

[0051] Taking advantage of the fact that the weight 205 moves outward due to centrifugal force, a sliding rod 211 is provided inside the device. When the counterweight 205 moves outward and contacts the side of the sliding rod 211, the sliding rod 211 is pressed and moves outward along the inner wall of the rotating ring 210, forcing the roller 212 to contact the compressed arc plate 308. In this process, the compressed arc plate 308 and the telescopic slide plate 309 form a retractable and expandable circle, presenting a Fig. 9In the state, the roller 212 contacts the inner wall of the circle and forces the circle to expand. The expanded circle will push the sliding square rod 307 to expand around along the through hole of the fixed bracket 301. At this time, the sliding square rod 307 will push the sealing slide plate 305 to spread around, so that different gaps appear between the sealing slide plates 305, such as Fig.10 In the state shown, the air on the inner wall of the sealing plate 305 enters the box to be cooled through the gaps. By using the above components, the external air enters the box through several gaps, the flow rate is increased, and the cooling efficiency of the equipment on the box is improved. By utilizing the characteristic that the sealing plate 305 expands outward during operation, a rotating shield 311 is provided inside the equipment. When the sealing plate 305 does not expand outward, the sealing plate 305 and the L-shaped rod 310 are in the state shown in the state shown. Fig. 9 In the state shown, a large gap is formed between the rotating baffle 311 and the fixed bracket 301. In this process, since a slide rail 209 is provided inside the equipment, when the counterweight 205 has not entered the slide rail 209, the sealing slide 305 has not been squeezed by the sliding square rod 307, and several sealing slides 305 are in a closed state. When the counterweight 205 cleans the surface of the sliding fan blade 204, the removed dust mixes with the air and acts on the inner wall of the sealing slide 305, and a reverse flow is generated, which enters the interior of the debris collection pipe 302 from the gap between the rotating baffle 311 and the fixed bracket 301, and is finally discharged outward from the impurity outlet 214. Through the application of the above-mentioned components, the total amount of dust entering the interior of the equipment can be effectively reduced.

[0052] The above-mentioned device is installed in a desert location with a fast wind speed. An air guide plate 105 is arranged inside the device. When a fast wind speed is generated outside, the air guide plate 105 swings due to the wind force, causing the rotating cylinder 103 and the air inlet 104 to rotate synchronously. The air guide plate 105 is parallel to the direction of the wind flow, so that the air inlet 104 is always on the leeward side, so that the device can minimize the content of sand and dust when collecting air from the external environment, and as the rotating cylinder 103 rotates, the cleaning frame 107 will scrape the outer wall of the filter plate 106 to remove impurities stuck to the outer wall of the filter plate 106; in addition, when the sealing slide plate 305 expands outward, the sealing slide plate 305 drives the rotating shield plate 311 to be tightly attached to the inner wall of the fixed bracket 301 through the L-shaped rod 310, so that the fixed bracket 301 is in a closed state, so as to prevent the dust particles on the inner wall of the miscellaneous material collection pipe 302 from being brought into the cooling box when the device transmits gas through the sealing slide plate 305, thereby affecting the dustproof effect of the equipment.
