Description

Technical Field

[0001] This invention relates to the field of wellhead antifreeze technology, and in particular to an integrated intelligent mine wellhead antifreeze system based on remote intelligent control technology. Background Technology

[0002] In winter, to prevent icing at the coal mine entrance and create a safe working environment, hot air blowers need to be installed at the entrance. Existing hot air blowers circulate low-temperature, low-pressure gaseous refrigerant, transferring heat to the evaporator plate, lowering its temperature below ambient temperature. At this time, the hot air blower, through fan rotation, forces outside air through the evaporator plate, transferring heat from the outside air to the gaseous refrigerant, raising its temperature. The refrigerant then passes through the compressor and is compressed into a high-temperature, high-pressure gaseous refrigerant, which circulates to the heat exchanger and liquefies within it. During the heat release process, the refrigerant exchanges heat with the circulating water in the heat exchanger, raising the temperature of the circulating water. The circulating water then flows through pipes to the location requiring heating. However, due to the high dust content in the air during coal mine operations, the fans accumulate dust quickly during operation. Workers need to periodically turn off the hot air blower and clean the dust on the fan, which reduces the thermal efficiency of the hot air blower. At the same time, the dust adhering to the fan affects the airflow distribution, reducing the efficiency of the fan in transporting gas. This reduces the efficiency of heat exchange between the refrigerant and the outside gas per unit time, resulting in a decrease in the thermal efficiency of the hot air blower. Summary of the Invention

[0003] This invention provides an integrated intelligent mine wellhead antifreeze system based on remote intelligent control technology to overcome the disadvantages of rapid ash accumulation in fans, which leads to increased energy consumption and reduced gas delivery efficiency.

[0004] The technical solution is: a smart mine shaft anti-freezing integrated system based on remote intelligent control technology, comprising a shell, on which a uniformly distributed protective net is fixedly attached; two symmetrically distributed sets of evaporators are installed inside the shell, each set of evaporators including symmetrically distributed evaporators; a temperature sensor is installed inside each evaporator; rectangularly distributed motors are mounted inside the shell via a bracket; the output shaft of each motor is fixedly connected to a mounting shaft; annularly distributed fan blades are fixedly connected to the side of the mounting shaft away from the adjacent motor; a sliding ring is slidably connected to the mounting shaft; a spring is fixedly connected between the side of the sliding ring away from the adjacent motor and the adjacent mounting shaft; and annular... A connecting rod, with the same number of fan blades distributed in an adjacent ring, is provided. A compression post is slidably connected to the side of the connecting rod away from the adjacent sliding ring. A spring is fixed between the compression post and the adjacent connecting rod. The compression post is used to cause the adjacent fan blades to vibrate. Rectangularly distributed compression rings are fixed inside the housing via a bracket. The compression rings contact the side of the adjacent sliding ring closest to the adjacent motor. The compression rings have protrusions. The sliding rings have hemispherical grooves that compress and engage with the protrusions of the adjacent compression rings. The evaporator, the motor, and the temperature sensor are all connected to a remote control terminal. A speed measuring component for detecting the rotational speed is provided on the mounting shaft.

[0005] Furthermore, a limiting block is provided within the mounting shaft near the adjacent sliding ring for slidable positioning. A tension spring is fixed between the limiting block and the adjacent mounting shaft. The sliding ring is provided with a limiting groove that cooperates with the adjacent limiting block for positioning.

[0006] Furthermore, the speed measuring component includes symmetrically distributed weights, which are sealed and slidably connected to adjacent mounting shafts, and a tension spring is fixed between them. The side of the weights closest to the central axis of the adjacent mounting shaft cooperates with the adjacent mounting shaft to form an extraction cavity. A transfer ring is fixedly connected to the compression ring, which is sealed and rotatably connected to the adjacent mounting shaft, and the two cooperate to form a transfer cavity. The extraction cavity communicates with the adjacent transfer cavity. Both the extraction cavity and the transfer cavity contain hydraulic oil. A collection component for assisting in cleaning all the fan blades is provided inside the housing.

[0007] Furthermore, the collection assembly includes symmetrically distributed partitions fixed within the housing and in contact with symmetrically distributed evaporators in the same group. The partitions are fixed to symmetrically distributed base plates, which are hinged to the base plates. The flow dividers are in contact with adjacent evaporators. The base plates are slidably connected to a power component, which is internally sealed with symmetrically distributed T-shaped components. The symmetrically distributed T-shaped components cooperate with adjacent power components to form a power chamber. The power chamber is connected to an adjacent transfer chamber via a conduit. Hydraulic oil is stored in the power chamber. The T-shaped components are hinged to adjacent flow dividers, and the symmetrically distributed flow dividers on the same base plate are in contact with each other.

[0008] Furthermore, it also includes a rectangularly distributed sealing mechanism, each used to seal the housing. The sealing mechanism is located on the housing near the mounting shaft. The sealing mechanism includes a fixing member, which is fixed to the side of the housing near the adjacent mounting shaft. The fixing member is splined to a sliding shaft, which has a guide groove. A top cover is fixed to the side of the sliding shaft away from the adjacent mounting shaft. A pressure sensor connected to a remote control terminal is installed on the side of the top cover near the housing. A tension spring is fixed between the fixing member and the adjacent top cover. A protective ring is fixed to the side of the top cover near the adjacent mounting shaft. The protective ring is slidably connected to the housing. A U-shaped member that slidably engages with the adjacent guide groove is slidably connected to the mounting shaft.

[0009] Furthermore, the depth of the guide groove is greater than the depth of the spline groove on the sliding shaft.

[0010] Furthermore, it also includes a rectangularly distributed cleaning mechanism, which is located on the housing near the top cover. The cleaning mechanism is used to prevent adjacent protective rings from being blocked. The cleaning mechanism includes a sealing ring, which is slidably connected to the adjacent protective ring. The sealing ring is slidably connected to a mounting ring. A ring-shaped limiting member is fixed to the side of the mounting ring away from the housing. The limiting member is slidably connected to the adjacent sealing ring. The top cover is provided with a ring-shaped recess. An electric push rod is installed on the housing. The telescopic end of the electric push rod is slidably connected to the adjacent mounting ring, and a spring is fixed between the two. The electric push rod is signal-connected to a remote control terminal.

[0011] Furthermore, the depth of the recess on the top cover is equal to the difference between the height of the limiting member and the thickness of the sealing ring near the adjacent top cover.

[0012] Furthermore, the sealing ring has annularly distributed extrusion blocks fixed to the side away from the adjacent mounting shaft, and the protective ring has annularly distributed extrusion grooves, with the extrusion blocks sliding within the adjacent extrusion grooves.

[0013] Furthermore, an elastic ring is fixedly connected to the sealing ring, the elastic ring is press-fitted with the adjacent mounting ring, the sealing ring is provided with an annular groove near the adjacent elastic ring, and the mounting ring is provided with a reset inclined surface that press-fits with the adjacent elastic ring on the side away from the adjacent top cover.

[0014] The advantages and positive effects of this invention compared with the prior art are as follows: This invention monitors the temperature change during the heat exchange process between the refrigerant and the outside environment, remotely controls the rotation speed of the fan blades, and knocks the fan blades when the rotation speed is slow, causing the dust on them to fall off due to vibration. This reduces the volume of dust on the fan blades, thereby reducing the impact of dust on gas flow, reducing energy consumption, and maintaining stable working efficiency of the fan blades.

[0015] By initially covering adjacent fan blades with the top cover, the volume of dust on the fan blades is reduced when the hot air blower is not started, which reduces the difficulty for workers to clean the fan blades and improves work efficiency.

[0016] The protective ring intercepts the plastic bag moving towards the fan blades. Then, the sealing ring and the top cover work together to compress the plastic bag into a flat shape, reducing its volume and thus reducing the impact of external gas flow on the plastic bag. This prevents the plastic bag from affecting the connection area of ​​the protective ring, ensuring the stability of the air intake during the operation of the hot air blower.

Detailed Implementation

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0032] In winter, to prevent coal mine entrances from freezing and to create a safe working environment, hot air blowers need to be installed at the entrances. However, due to the high dust content in the air during coal mine operations, the fans accumulate dust quickly when they are working. Workers need to regularly turn off the hot air blowers and clean the dust off the fans, which reduces the thermal efficiency of the hot air blowers. At the same time, the dust attached to the fans affects the distribution of airflow and reduces the efficiency of the fans in transporting gas.

[0033] Example 1: A smart mine wellhead antifreeze integrated system based on remote intelligent control technology, please refer to... Figures 1-5 The system includes a housing 1, on which a uniformly distributed protective net 2 is fixed. The protective net 2 is used to discharge gas from the housing 1 and to protect the components inside the housing 1. Two sets of evaporators 3 are installed symmetrically front to back inside the housing 1. Each set of evaporators 3 includes two evaporators 3 symmetrically distributed front to back. In the left-right direction, the two evaporators 3 in each set are installed in a V-shape. A compressor, a heat exchanger, and an expansion valve are installed inside the housing 1. The compressor, heat exchanger, expansion valve, and evaporators 3 together form a heat exchange system (the heat exchange system is existing technology and will not be described in detail here). A temperature sensor is installed inside the evaporator 3 to monitor the temperature of the refrigerant inside. Four rectangularly distributed motors 4 are mounted inside the housing 1 via brackets. The output shaft of the motor 4 is fixed to a mounting shaft 5. Four annularly distributed fan blades 6 are fixed to the upper side of the mounting shaft 5. The mounting shaft 5 is slidably connected to the upper and lower limits by sliding rings. 7. A spring is fixed between the upper side of the sliding ring 7 and the adjacent mounting shaft 5. Four connecting rods 8 are fixedly connected to the sliding ring 7 in a ring. The connecting rods 8 are slidably connected to the upper and lower limits of the side away from the adjacent sliding ring 7. A spring is fixed between the lower side of the extrusion column 9 and the adjacent connecting rod 8. The extrusion column 9 is used to make the adjacent fan blade 6 vibrate. Four extrusion rings 10 are fixedly connected to the housing 1 in a rectangular distribution through a bracket. The extrusion rings 10 are in contact with the lower side of the adjacent sliding ring 7. The upper side of the extrusion ring 10 is provided with several protrusions in a ring. The lower side of the sliding ring 7 is provided with several hemispherical grooves in a ring. The hemispherical grooves on the sliding ring 7 are pressed and engaged with the adjacent protrusions on the adjacent extrusion ring 10 to make the sliding ring 7 move up and down. The heat exchange system, motor 4 and temperature sensor are all connected to the remote control terminal signal. A speed measuring component for detecting its rotation speed is provided at the lower part of the mounting shaft 5.

[0034] Please refer to Figure 5 The middle part of the mounting shaft 5 is connected to the left and right limit sliding connection of the limit block 11. The right side of the limit block 11 is fixed to the adjacent mounting shaft 5 with a tension spring. The sliding ring 7 is provided with a limit groove 111. The limit groove 111 cooperates with the adjacent limit block 11 to limit the sliding ring 7.

[0035] Please refer to Figure 5 and Figure 6The speed measuring component includes two symmetrically distributed weights 12. The weights 12 are slidably and sealed to the adjacent mounting shafts 5. A tension spring is fixed between the weights 12 and the mounting shafts 5. The side of the weights 12 closest to the center axis of the adjacent mounting shafts 5 cooperates with the adjacent mounting shafts 5 to form an extraction cavity 121. A transfer ring 13 is fixed to the lower side of the compression ring 10. The transfer ring 13 is rotatably and sealed to the adjacent mounting shafts 5. The two cooperate to form a transfer cavity 131 that communicates with the adjacent extraction cavity 121. Hydraulic oil is stored in both the extraction cavity 121 and the transfer cavity 131. A collection component for assisting in cleaning all fan blades 6 is provided inside the housing 1.

[0036] Please refer to Figure 2 , Figure 7 and Figure 8 The collecting assembly includes two partitions 14 symmetrically distributed front and back. The partitions 14 are fixed inside the housing 1 and contact the opposing sides of two evaporators 3 symmetrically distributed in the same group. The partitions 14 are fixed to two bottom plates 15 symmetrically distributed left and right. The bottom plates 15 are hinged to two flow dividers 16 symmetrically distributed front and back. The two flow dividers 16 on the same bottom plate 15 are in contact with each other. The bottom plate 15 and the two adjacent flow dividers 16 form a triangular prism to guide the gas flow. The flow dividers 16 are in contact with the adjacent evaporators 3. The upper middle part of the bottom plate 15 is slidably connected to a power member 17 with upper and lower limits. The power member 17 is slidably connected to two T-shaped members 18 symmetrically distributed front and back with front and rear sealing. The opposing sides of the two T-shaped members 18 cooperate with the adjacent power member 17 to form a power chamber 181. The power chamber 181 is connected to the adjacent transfer chamber 131 through a conduit. The power chamber 181 contains hydraulic oil. The T-shaped members 18 are hinged to the adjacent flow dividers 16.

[0037] When using hot air blowers to prevent icing at coal mine entrances during winter, workers remotely control four motors 4 (described here using the parts on the front left side) and the heat exchange system. The output shafts of motors 4 are set to have normal and low speeds. Initially, motors 4 operate at normal speed. As the speed of motors 4 gradually increases to normal, the output shaft of motors 4 drives the fan blades 6 and sliding rings 7 to rotate clockwise via the mounting shaft 5 (the rotation angle in this article is from top to bottom). Sliding rings 7 drive four connecting rods 8 to rotate. As sliding rings 7 rotate, the hemispherical grooves on sliding rings 7 misalign with the adjacent protrusions on the compression rings 10, causing the compression rings 10 to... The protrusion on the 0 presses the sliding ring 7 upward and compresses the spring adjacent to the sliding ring 7. The sliding ring 7 drives the four connecting rods 8 to move upward, and the connecting rods 8 drive the adjacent extrusion column 9 to move upward, so that the extrusion column 9 contacts and collides with the adjacent fan blade 6, causing the fan blade 6 to vibrate and shake off the dust on the fan blade 6. As the sliding ring 7 rotates, the hemispherical groove on the sliding ring 7 corresponds to the upper and lower protrusions of the extrusion ring 10. At this time, the sliding ring 7 moves downward and resets under the action of the adjacent spring. The sliding ring 7 drives the extrusion column 9 to lose contact with the adjacent fan blade 6 through the connecting rod 8. Before the output shaft of the motor 4 reaches the normal speed, the above steps of the sliding ring 7 moving up and down are repeated.

[0038] When the output shaft of motor 4 reaches normal speed, the centrifugal force on the limiting block 11 is greater than the tension of its adjacent tension spring, causing the limiting block 11 to tend to move to the left. When the sliding ring 7 moves up again, the limiting block 11 corresponds to the limiting groove 111. At this time, the limiting block 11 moves to the left under the centrifugal force and stretches the adjacent tension spring, causing the limiting block 11 to enter the adjacent limiting groove 111 and limit the sliding ring 7, so that the sliding ring 7 stops moving up and down.

[0039] As the output shaft speed of motor 4 gradually reaches normal speed, mounting shaft 5 drives the weight 12 to rotate. When the output shaft of motor 4 reaches normal speed, the centrifugal force on the weight 12 is greater than the tension of its adjacent tension spring. At this time, the two weights 12 move away from each other and increase the volume of the two extraction chambers 121. The extraction chambers 121 extract the hydraulic oil in the power chamber 181 through the transfer chamber 131 and the adjacent conduit, reducing the volume of the hydraulic oil in the power chamber 181. The two T-shaped pieces 18 drive the adjacent diverter plates 16 to move closer to each other until the upper sides of the two diverter plates 16 contact each other. At this time, the T-shaped pieces 18 stop moving. The two diverter plates 16 and the bottom plate 15 form a triangle, causing the gas entering the housing 1 to collide with the two diverter plates 16 and flow along their sides, and finally contact the sides of the two evaporators 3.

[0040] When the output shaft of motor 4 is running at normal speed, the temperature sensor monitors the temperature change of the refrigerant in evaporator 3 (when dust accumulates on fan blade 6, the volume of gas passing through evaporator 3 per unit time decreases, which reduces the heat exchange efficiency between the refrigerant in evaporator 3 and the outside gas, i.e., the temperature change of the refrigerant in evaporator 3 becomes smaller). Subsequently, the worker remotely controls the output shaft speed of motor 4 to decrease to a low speed. At this time, the centrifugal force on limit block 11 and weight block 12 is less than the tension of their adjacent tension springs, causing limit block 11 to move to the right and reset. Limit block 11 loses contact with limit groove 111 and releases the limit on sliding ring 7. Then, the above steps of sliding ring 7 moving up and down are repeated. The squeezing column 9 collides with the adjacent fan blade 6 and causes the dust on the fan blade 6 to fall due to vibration. At the same time, the two weight blocks 12 move closer to each other and reset under the action of their adjacent tension springs, squeezing the hydraulic oil in the adjacent extraction chamber 121 into the power chamber 181, causing the two T-shaped parts 18 to move away from each other and push the adjacent diverter plate 1. The fan blade 6 rotates and contacts the adjacent evaporator 3 to reset. During the process of the extrusion column 9 colliding with the adjacent fan blade 6 and causing dust on the fan blade 6 to fall off, the fan blade 6 continues to guide the outside gas into the housing 1. At the same time, the outside gas carries the dust falling from the fan blade 6 onto the bottom plate 15 and the two diversion plates 16. Then, the gas entering the housing 1 blows the dust along the bottom plate 15 to the left and finally passes through the adjacent protective net 2 and exits the housing 1. After the motor 4 runs at a low speed for a period of time (the period of time here is determined by the dust content in the local air), the worker controls the speed of the motor 4 to increase to the normal speed through the remote control terminal. In this way, the temperature sensor monitors the temperature change of the refrigerant in the evaporator 3 and controls the output shaft of the motor 4 to switch between normal speed and low speed to clean the dust on the fan blade 6, reduce the impact of the dust on the fan blade 6 on the gas flow, and thus maintain the stable working efficiency of the fan blade 6. When the hot air blower is not needed, the worker remotely controls the heat exchange system, motor 4 and temperature sensor to stop.

[0041] Since hot air blowers are only used in winter and not needed in spring, summer and autumn, after a long period of inactivity, the fan blades exposed to the air accumulate a lot of dust. When they are put back into use, the fan blades need to be cleaned manually. However, the dust has been in contact with the fan blades for a long time, making the dust and the fan blades stick together tightly, which makes cleaning difficult.

[0042] Example 2: Based on Example 1, please refer to... Figure 1 , Figure 2 , Figure 6 , Figure 9 and Figure 10It also includes four sealing mechanisms arranged in a rectangular shape, each used to seal the housing 1. The sealing mechanisms are located on the upper side of the housing 1 and include a fixing member 19. The fixing member 19 is fixed to the upper side of the housing 1 near the adjacent mounting shaft 5. The fixing member 19 is splinedly connected to a sliding shaft 20 (i.e., the sliding shaft 20 has a spline groove). The sliding shaft 20 has a guide groove 201, which consists of an upper inclined portion and a lower horizontal portion. The depth of the guide groove 201 is greater than the depth of the spline groove on the sliding shaft 20. A top cover 21 is fixed to the upper side of the sliding shaft 20, and a lower mounting plate is installed inside the top cover 21. Equipped with a pressure sensor, the pressure sensor is used to monitor the air pressure under the top cover 21, thereby determining the sealing status of the protective ring 22. A tension spring is fixedly connected between the upper side of the fixing member 19 and the adjacent top cover 21. A protective ring 22 is fixedly connected to the lower side of the top cover 21. The protective ring 22 is an annular cylinder with holes. The protective ring 22 is used to prevent large particles from entering the housing 1. The protective ring 22 is slidably connected to the housing 1. A U-shaped member 23 is slidably connected to the left and right sides of the mounting shaft 5. The U-shaped member 23 is composed of a U-shaped rod, a left hemisphere and a right counterweight. The U-shaped member 23 is slidably engaged with the adjacent guide groove 201.

[0043] When the output shaft of motor 4 drives the mounting shaft 5 to rotate, the mounting shaft 5 drives the U-shaped part 23 to rotate circumferentially (at this time, the centrifugal force on the U-shaped part 23 is greater than the tension of the adjacent tension spring of the top cover 21). The U-shaped part 23 moves to the right due to the centrifugal force, and the hemisphere of the U-shaped part 23 enters the guide groove 201 and moves along it. The U-shaped part 23 pushes the sliding shaft 20 upward through the guide groove 201. The sliding shaft 20 drives the top cover 21 and the protective ring 22 to move upward and stretches the tension spring adjacent to the top cover 21 until the U-shaped part 23 moves to the end of the inclined part of the guide groove 201 and enters its horizontal part. At this time, the lower part of the protective ring 22 contacts the upper part of the housing 1. As the fan blade 6 rotates, the external gas is drawn into the housing 1 through the protective ring 22.

[0044] As the output shaft of motor 4 gradually stops rotating, top cover 21 moves downward under the action of its adjacent tension spring. At this time, the centrifugal force on U-shaped part 23 is less than the tension of the adjacent tension spring of top cover 21. Sliding shaft 20 pushes U-shaped part 23 to the left through guide groove 201, so that U-shaped part 23 loses contact with the horizontal part of guide groove 201. Then sliding shaft 20, top cover 21 and protective ring 22 move downward and reset together, covering housing 1 again and reducing the probability of external dust falling onto fan blade 6.

[0045] During the use of a hot air blower, if floating objects such as plastic bags come into contact with and become entangled in the fan blades, the fan blades are easily damaged. Therefore, a protective net is installed above the fan blades of existing hot air blowers. However, when a plastic bag falls onto the protective net, because the gas flows from the outside into the hot air blower, the plastic bag will stick to the protective net, reducing the ventilation area of ​​the protective net and thus reducing the working efficiency of the hot air blower.

[0046] Example 3: Based on Example 2, please refer to... Figure 11 and Figure 12 It also includes four cleaning mechanisms arranged in a rectangular pattern. These cleaning mechanisms are located on the housing 1 near the top cover 21. The cleaning mechanisms prevent adjacent protective rings 22 from being obstructed. Each cleaning mechanism includes a sealing ring 24, which is slidably connected vertically to the outside of the adjacent protective ring 22. An installation ring 25 is slidably connected vertically to the outside of the sealing ring 24. Several annularly distributed limiting members 26 are fixedly connected to the upper side of the installation ring 25. The limiting members 26 are mushroom-shaped and are used to allow the plastic bag to move downwards with the sealing ring 24. The limiting members 26 are slidably connected vertically to the adjacent sealing ring 24. The top cover 2... The lower side of the housing 1 has several recesses arranged in a ring, which provide space for the adjacent limiting member 26 to pass through the plastic bag. The diameter of the recess is larger than the maximum outer diameter of the adjacent limiting member 26. The depth of the recess on the top cover 21 is equal to the difference between the height of the limiting member 26 and the thickness of the upper part of the sealing ring 24. An electric push rod 27 is installed on the upper side of the housing 1. The telescopic end of the electric push rod 27 is slidably connected to the adjacent mounting ring 25. A spring is fixed between the lower side of the mounting ring 25 and the telescopic end of the electric push rod 27. The electric push rod 27 is connected to the remote control terminal signal.

[0047] Please refer to Figure 12 and Figure 13 A plurality of extrusion blocks 28 are fixedly connected to the upper side of the inner ring of the sealing ring 24. A plurality of extrusion grooves 281 are provided on the protective ring 22. The extrusion blocks 28 slide in adjacent extrusion grooves 281. An inclined surface is provided on the side of the extrusion block 28 away from the central axis of the protective ring 22 for scraping off the plastic bag attached to the protective ring 22.

[0048] Please refer to Figure 12 and Figure 13 An elastic ring 29 is fixedly connected to the sealing ring 24. The elastic ring 29 is made of elastic material. The elastic ring 29 is squeezed and fitted with the adjacent mounting ring 25. An annular groove 291 is provided on the sealing ring 24 near the adjacent elastic ring 29. The annular groove 291 is used to allow the adjacent elastic ring 29 to be deformed and located inside it, so that the mounting ring 25 can pass over the adjacent elastic ring 29. A reset inclined surface 292 is provided on the lower side of the inner ring of the mounting ring 25. The reset inclined surface 292 is squeezed and fitted with the adjacent elastic ring 29.

[0049] When the hot air blower is working normally, outside air passes through the protective ring 22 and enters the housing 1. When a plastic bag is attached to the protective ring 22, the volume of air entering the protective ring 22 per unit time is less than the volume of air that the fan blade 6 can draw in, causing the air pressure near the protective ring 22 to drop. At this time, the air pressure sensor on the top cover 21 detects the air pressure change and transmits a signal to the remote control terminal. Then, the worker starts the electric push rod 27 through the remote control terminal, causing the telescopic end of the electric push rod 27 to extend. The telescopic end of the electric push rod 27 drives the adjacent mounting ring 25 through the adjacent spring. The installation ring 25 moves upward by squeezing the sealing ring 24 through the elastic ring 29. The sealing ring 24 drives the limiting member 26 and the squeezing block 28 to move upward. The squeezing block 28 moves upward along the adjacent extrusion groove 281 and "scrapes off" the plastic bag attached to the protective ring 22, so that the plastic bag contacts the upper side of the sealing ring 24. As the sealing ring 24 moves upward, the sealing ring 24 pushes the plastic bag upward. At the same time, the upper part of the protective ring 22 still draws gas inward, so that the plastic bag adheres to the protective ring 22. In this way, when the sealing ring 24 moves upward, the plastic bag will be squeezed between the sealing ring 24 and the top cover 21.

[0050] After the sealing ring 24 squeezes the plastic bag between itself and the top cover 21 and flattens the plastic bag, the sealing ring 24 stops moving upward. As the telescopic end of the electric push rod 27 extends, the telescopic end of the electric push rod 27 moves upward relative to the mounting ring 25 and compresses the spring adjacent to the mounting ring 25. When the elastic force of the spring adjacent to the mounting ring 25 is greater than the deformation force of the elastic ring 29, the elastic ring 29 deforms and releases its restriction on the mounting ring 25. Subsequently, under the action of its adjacent spring, the mounting ring 25 drives the limiting member 26 to move upward quickly, so that the limiting member 26 passes through the sealing ring 24 and contacts the corresponding recess on the top cover 21. During this process, the limiting member 26 penetrates the plastic bag and enters the corresponding recess. At this time, the telescopic end of the electric push rod 27 extends to its limit, and the worker remotely controls the extension and retraction of the electric push rod 27. As the electric push rod 27 retracts, its telescopic end moves downward relative to the mounting ring 25, causing the spring adjacent to the mounting ring 25 to reset. Subsequently, the mounting ring 25 moves downward along with the telescopic end of the electric push rod 27. The reset inclined surface 292 contacts the elastic ring 29 and drives the sealing ring 24 downward through the elastic ring 29. The plastic bag moves downward along with the sealing ring 24 under the action of the limiting member 26 until the sealing ring 24 resets. The sealing ring 24 then stops moving. As the telescopic end of the electric push rod 27 retracts, it drives the mounting ring 25 downward. The reset inclined surface 292 compresses the elastic ring 29, causing it to deform and release the elastic ring 29 from its limiting position on the mounting ring 25. At this time, the mounting ring 25 moves downward and resets. After the mounting ring 25 resets, the elastic ring 29 recovers its deformation and re-limits the mounting ring 25.

[0051] During the process of the mounting ring 25 moving down and resetting along the sealing ring 24, the mounting ring 25 drives the limiting member 26 to move down, causing the limiting member 26 to deform the plastic bag and gradually retract into the sealing ring 24. At this time, the plastic bag is restricted by the limiting member 26, reducing its volume and reducing the influence of gas flow on the plastic bag. Therefore, the plastic bag cannot affect the connection area of ​​the protective ring 22. After the hot air blower stops, the workers inspect the hot air blower where the plastic bag appeared and clean the plastic bag remaining on the sealing ring 24.

[0052] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating this application and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this application.
