Description

Technical Field

[0001] The present invention belongs to the technical field of purification and adsorption treatment of soot and dust, and particularly relates to a blasting soot elimination device and an elimination method. Background Art

[0002] Blasting operations are widely used in fields such as mining, tunnel excavation, building demolition, and water conservancy projects. However, a large amount of soot (including dust particles and harmful gases such as CO, NOx, SO2, etc.) is generated during the blasting process, which not only seriously pollutes the environment but also poses a threat to the health of operating personnel (such as causing pneumoconiosis, respiratory diseases, etc.). At the same time, it reduces the visibility on site, affecting the safety and efficiency of subsequent operations. Therefore, the development of an efficient blasting soot elimination device is an important requirement for the sustainable development of the industry;

[0003] Traditional spray and sprinkler systems (such as fixed spraying and vehicle-mounted spraying) rely on natural diffusion and have limited ability to capture long-distance or high-concentration soot. Moreover, since the water content in the air increases during the spraying process, the increased water content causes the inside of the filter screen to become wet, resulting in dust accumulation inside the filter screen, thus affecting the filtering effect. Summary of the Invention

[0004] In view of the problem in the prior art that the water content in the air increases during the spraying process, and the increased water content causes the inside of the filter screen to become wet, resulting in dust accumulation inside the filter screen, thus affecting the filtering effect, the present invention proposes the following technical solutions:

[0015] As a preference of the above technical solution, the support structure includes:

[0016] A disc, connected to the circular tube, the number of the discs is set to four in total, and the four discs are vertically arranged at equal intervals along the horizontal plane;

[0017] Vent holes, arranged in the disc, and are arranged in a circle along the center point of the disc;

[0018] A solid disc, connected to the middle of the disc, and a hollow interlayer is arranged inside the solid disc;

[0019] A partition cover, connected to one end of the solid disc, and used for splitting the gas.

[0020] As a preference of the above technical solution, rectangular grooves are symmetrically opened on the outside of the partition cover, round holes are opened at the center points of the solid disc and the filter net, and an inclined angle is opened at the edge of one end of the partition cover close to the fan blade.

[0021] As a preference of the above technical solution, the staggered flow splitting structure includes:

[0022] A mounting rod, connected to the circular tube;

[0023] A connecting ring, connected to the mounting rod, and the mounting rod supports the connecting ring so that the center line of the connecting ring coincides with the center line of the circular tube;

[0024] A lifting member, connected to the connecting ring;

[0025] A rotating sleeve, the rotating sleeve is connected to the lifting member, and the lifting member drives the rotating sleeve to move.

[0026] Preferably, as the above technical solution, the staggered flow splitting structure further includes:

[0028] A connecting bar, connected to the barrier disk;

[0036] Preferably, the number of the metal rotors is set to four in total. The metal rotor close to the atomizing structure is fixedly connected to the rotating column. Limiting strips are provided on the outer sides of the other three metal rotors. The limiting strips are connected to the rotating column. Guide grooves are provided on the outer side of the rotating sleeve corresponding to the outer sides of the limiting strips.

[0037] The present invention also provides a method for using the above blasting fume elimination device, including the following steps:

[0038] Step 1: Use a vehicle frame to transport the whole blasting fume elimination device to the blasting operation site;

[0039] Step 2: Start the driving member. The driving member rotates to drive the fan blades to rotate synchronously, forming an air flow inside the conical cylinder. The air flow blows towards the blasting fume area along the axis of the conical cylinder;

[0040] Step 3: The water source stored in the water tank is processed by the atomizing structure and converted into water mist. At this time, the air flow generated by the driving member carries the atomized water droplets and covers the blasting fume area in a spraying manner;

[0041] Step 4: After the gas containing adsorbed soot enters the heating and filtering assembly, it is shunted by means of an interleaved shunt structure. The gas is distributed to two groups of filter meshes for filtration. The other two groups of filter meshes are heated and dried under the action of the heat generated by the rotation between the metal rotor and the metal stator. Finally, the purified gas re-enters the middle of the atomization structure along the conical cylinder and is mixed with the water mist. At the same time, the filter meshes are used alternately, so that the heated filter meshes are used for filtration, and the filtered filter meshes are heated and dried.

[0042] The beneficial effects of the present invention are as follows:

[0043] (1) This device adopts a heating and filtering assembly. The metal rotor and the metal stator generate heat by friction, which is transmitted to the filter mesh through the heat conduction column, keeping it in a dry state, preventing dust from adhering and accumulating due to moisture. In cooperation with the interleaved shunt structure, the two groups of filter meshes can work alternately. When one group is filtering, the other group is heated and dried, avoiding continuous moisture absorption of the filter mesh. This not only ensures the stability of the filtering effect but also reduces the corrosion and aging of the filter mesh caused by moisture, greatly extending the service life of the filter mesh and reducing the maintenance cost and frequency.

[0044] (2) This device drives the fan blades to rotate at high speed through the driving member, forming a strong negative pressure air flow in the conical cylinder, which can actively adsorb soot at a long distance and introduce the dust-containing gas into the device. At the same time, the atomization structure and the heating and filtering assembly work together. First, the large-particle dust is captured by the water mist, and then the fine particles are intercepted by the filter mesh. Even in the face of high-concentration soot, efficient purification can be achieved, significantly improving the dust removal efficiency and effectively solving the problem of insufficient capture ability of traditional systems for long-distance and high-concentration soot.

Detailed implementation manners

[0058] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0059] Embodiment 1: The present invention provides a blasting dust elimination device, as Figures 1 to 12As shown in the figure, it includes: a frame 1, a rotating frame 2, a conical cylinder 3, a driving member 4, a fan blade 5, a water tank 12, and a heating and filtering assembly. The frame 1 is used for supporting the overall blasting dust elimination device; the water tank 12 is connected to the top edge of the frame 1; the rotating frame 2 is connected to the top of the frame 1; the conical cylinder 3 is connected to the rotating frame 2; the driving member 4 is connected to the inside of the conical cylinder 3; the fan blade 5 is connected to the output shaft of the driving member 4, and the driving member 4 drives the gas to flow through the fan blade 5; the heating and filtering assembly includes: a circular tube 6, a support structure, a heat conducting column 75, a filter net 76, an alternating flow splitting structure, a metal rotor 91, a metal stator 92, and a connection structure; the circular tube 6 is connected to the inside of the conical cylinder 3, the support structure is connected to the inside of the circular tube 6, the heat conducting column 75 is connected to the support structure, the filter net 76 is sleeved outside the heat conducting column 75, the alternating flow splitting structure is connected to the outside of the support structure, the metal rotor 91 is connected to the inside of the support structure, the metal stator 92 is sleeved outside the metal rotor 91, and the connection structure is connected to the middle of the circular tube 6.

[0060] During blasting operations, spray dust suppression will increase the water content in the air, causing the filter net 76 to get damp, resulting in dust accumulation and clogging of the filter pores, reducing the filtering effect. Through the heating and filtering assembly, the present invention keeps the filter net 76 dry, which can not only prevent dust from adhering and accumulating due to wetness, maintain smooth air flow and high filtering performance, but also reduce the corrosion and aging of the filter net 76 caused by dampness, extend its service life, and reduce maintenance costs. In addition, in the dry state, the filter net 76 can utilize the principle of thermal expansion and contraction to promote the detachment of particulate matter, and cooperate with the alternating flow splitting structure to achieve an alternating cycle of filtering and cleaning, ensuring the continuous and stable operation of the device, and significantly improving the overall dust removal efficiency.

[0061] During use, the device is transported to a pre-determined location by the vehicle frame 1. The rollers at the bottom of the vehicle frame 1 can be used to flexibly adjust the position of the device. Subsequently, the drive motor inside the vehicle frame 1 is started to drive the rotating frame 2 to swing the conical cylinder 3 to a predetermined position along the horizontal plane (X-axis). Then, through the electric lifting rod between the bottom end of the conical cylinder 3 and the top end of the rotating frame 2, the angle of the conical cylinder 3 along the vertical plane (Y-axis) is adjusted until the angle between it and the ground reaches the predetermined angle and is fixed. Then, the driving member 4 (specifically a stepping motor) is started. When the driving member 4 operates, it drives the fan blade 5 to rotate. When the fan blade 5 rotates, the gas moves along the middle of the conical cylinder 3 (axial movement). The gas moving along the inside of the conical cylinder 3 enters the staggered flow splitting structure. The staggered flow splitting structure evenly distributes the gas to two of the filter meshes 76 for filtering, and the other two filter meshes 76 do not participate in the filtering temporarily. At the same time, the metal rotor 91 rotates synchronously with the drive shaft of the driving member 4 through the connection structure. At this time, the metal stator 92 remains fixed. When the metal rotor 91 rotates, the fluid molecules between its surface and the metal stator 92 generate frictional heat due to viscous action. The heat enters the inside of the filter mesh 76 through the heat conducting columns 75, causing different positions inside the filter mesh 76 to be heated, so that the filter mesh 76 remains dry, and the filter mesh 76 is fixed under the action of the support structure.

[0062] Specifically, four rollers are installed at the bottom end of the vehicle frame 1. A frame is welded to the edge of the top end of the vehicle frame 1. The water tank 12 is arranged inside the frame. A valve is embedded at one end of the water tank 12 for controlling the water flow. A drive motor is installed inside the vehicle frame 1. The output shaft of the drive motor is connected with the rotating frame 2 by a key. The rotating frame 2 is sleeved inside the vehicle frame 1 and is rotatably connected with the vehicle frame 1. Two rotating rods are symmetrically and rotatably connected inside the rotating frame 2 through bearings. A conical cylinder 3 is fixedly installed between the two rotating rods. An atomizing structure 11 is installed at the end of the conical cylinder 3 close to the smallest diameter. A water pump is installed inside the vehicle frame 1 on one side of the drive motor. The water inlet end of the water pump is connected to the valve through a pipeline, and the water outlet end of the water pump is connected to the atomizing structure 11. The atomizing structure 11 is composed of a metal ring and a nozzle. At this time, water evenly enters into a plurality of nozzles along the inside of the metal ring, and the water in the water tank 12 can be transported to the atomizing structure 11 and sprayed out as a misty liquid from the nozzles after being evenly distributed by the metal ring. An electric lifting rod is rotatably connected between the bottom end of the conical cylinder 3 and the top end of the rotating frame 2. The electric lifting rod between the conical cylinder 3 and the rotating frame 2 can adjust the pitching angle of the conical cylinder 3 to meet the requirements of different working scenarios (the above structures are all prior arts and will not be elaborated here).

[0063] A driving member 4 is installed at one end of the conical cylinder 3 close to the largest diameter. A fan blade 5 is installed on the outside of the output shaft of the driving member 4 through a flat key. A circular tube 6 is installed at a position inside the conical cylinder 3 close to the fan blade 5. A support structure is installed inside the circular tube 6. The number of the support structures is set to four in total (as Figure 7As shown, heat-conducting columns 75 are evenly installed inside the four support structures at equal intervals. A filter screen 76 is sleeved outside the heat-conducting columns 75. Interleaved flow-distributing structures are installed on one end face of the four support structures. Metal rotors 91 are rotatably connected inside the four support structures. A metal stator 92 is arranged outside the metal rotors 91. One end of the output shaft of the driving member 4 is installed with a connecting structure.

[0064] In the present invention, the driving member 4 belongs to a structure for driving an object to rotate, and specifically belongs to a stepping motor.

[0065] To facilitate the installation and disassembly of the circular tube 6, an arc-shaped block is welded on the back of the circular tube 6. A fixing bolt is threadedly penetrated through the inside of the arc-shaped block. The fixing bolt and the conical tube 3 are threadedly connected. The circular tube 6 is fixed to the conical tube 3 through the fixing bolt. And to facilitate the dumping of impurities filtered inside the circular tube 6, a discharge groove is opened at the lowest point on the outer surface of the circular tube 6 in the position with the ground. A barrier cover is installed inside the discharge groove on the outside of the circular tube 6 through screws. At this time, the discharge groove is blocked by the barrier cover to prevent the phenomenon that dust during the filtering process enters the inside of the circular tube 6 along the discharge groove. And under the action of the barrier cover, it is convenient to clean the dirt filtered inside the circular tube 6.

[0066] As Figure 2 and Figure 10 As shown, the connecting structure includes: a mounting cover 101, a mounting block 102, a bolt 103, and a rotating column 104; the mounting cover 101 is connected to the driving member 4; the mounting block 102 is inserted into the mounting cover 101; the bolt 103 is inserted through the mounting block 102 and the mounting cover 101; the rotating column 104 is connected to the mounting block 102.

[0067] Since it is necessary to drive the metal rotor 91 to rotate, the metal rotor 91 is connected to the driving member 4 through the connecting structure, so that the metal rotor 91 can be driven to rotate during the rotation of the driving member 4. The metal rotor 91 is made of copper, and the metal stator 92 is made of iron. When the two cooperate to rotate, the metal rotor 91 drives the gas to flow along the inner side of the metal stator 92, generating heat due to friction.

[0068] During use, insert the mounting block 102 into the inside of the mounting cover 101, and then penetrate the bolt 103 between the mounting cover 101 and the mounting block 102. At this time, the mounting cover 101 and the mounting block 102 are fixed, so that the rotating column 104 is fixed. After the rotating column 104 is fixed, the position of the circular tube 6 is fixed through the support structure, and then the circular tube 6 and the conical tube 3 are fixed.

[0069] Specifically, one end of the output shaft of the driving member 4 is welded with an installation cover 101. An installation block 102 is inserted into the installation cover 101. A bolt 103 is connected through the installation block 102 and one end face of the installation cover 101. The bolt 103 is composed of a screw rod and a nut. The screw rod penetrates through the installation block 102 and the installation cover 101. The nut is threadedly connected to the outer side of the screw rod and is located at the other end of the installation cover 101, thereby fixing the rotating column 104. Then, the circular tube 6 is fixed through the support structure. Finally, the circular tube 6 is fixed to the conical cylinder 3. The rotating column 104 is rotatably connected to the inside of the solid disk 73. The materials of the metal rotor 91 and the metal stator 92 are copper and iron respectively.

[0070] As a preference of the above technical solution, the staggered flow splitting structure includes: an installation rod 81, a connecting ring 82, a lifting member 83, a rotating sleeve 84, a blocking disk 85, a connecting bar 86, a flow splitting cover 87, and a notch 88; the installation rod 81 is connected to the circular tube 6; the connecting ring 82 is connected to the installation rod 81. The installation rod 81 supports the connecting ring 82 to make the center line of the connecting ring 82 coincide with the center line of the circular tube 6; the lifting member 83 is connected to the connecting ring 82; the rotating sleeve 84 is connected to the lifting member 83. The lifting member 83 drives the rotating sleeve 84 to move; the blocking disk 85 is connected to the rotating sleeve 84; the connecting bar 86 is connected to the blocking disk 85; the flow splitting cover 87 is connected to the connecting bar 86; the notch 88 is arranged on the outer side of the flow splitting cover 87.

[0071] Since the filter screen 76 becomes wet due to the interference of moisture after being used in a gas with a relatively high moisture content, which affects the normal use of the filter screen 76. During this process, the filter screen 76 cannot be used. At this time, the gas is split through the staggered flow splitting structure, so that part of the gas enters part of the filter screens 76, and the remaining filter screens 76 are in a dry environment, realizing the alternative use of the filter screens 76 (as Figure 7 shown).

[0072] During use, the lifting member 83 drives the rotating sleeve 84 to move. When the rotating sleeve 84 moves, it drives the blocking disk 85 to move. When the blocking disk 85 moves, it drives the flow dividing cover 87 to move through the connecting bar 86, so that the notch 88 of the flow dividing cover 87 is exposed outside one end of the partition cover 74. At the same time, the rectangular groove opened on the outside of the partition cover 74 is blocked by the flow dividing cover 87, and at the same time, the blocking disk 85 enters the hole in the middle of the partition cover 74. Since the numbers of both the flow dividing cover 87 and the blocking disk 85 are set to four, the four flow dividing covers 87 and blocking disks 85 cooperate. At this time, the notch 88 of the first flow dividing cover 87 fits with the outside of the partition cover 74 to close the notch 88, while the notch 88 of the second flow dividing cover 87 is exposed outside the partition cover 74 to form an opening and closing state. The notch 88 of the third flow dividing cover 87 fits with the outside of the partition cover 74 to close the notch 88, and the notch 88 of the fourth flow dividing cover 87 is exposed outside the partition cover 74 to form an opening and closing state. At the same time, the first blocking disk 85 separates from the hole in the middle of the partition cover 74, the second blocking disk 85 enters the hole in the middle of the partition cover 74 and fits with it, the third blocking disk 85 separates from the hole in the middle of the partition cover 74, and the fourth blocking disk 85 enters the hole in the middle of the partition cover 74 and fits with it. And through the rotating sleeve 84, multiple blocking disks 85 and multiple flow dividing covers 87 all move synchronously (as Figure 7 shown).

[0073] Four mounting rods 81 are circumferentially arranged inside the circular tube 6. The same connecting ring 82 is welded between the four mounting rods 81. A rotating sleeve 84 is embedded and installed on one end face of the connecting ring 82 close to the atomizing structure 11. The rotating sleeve 84 is composed of a rotating ring and a positioning ring. Among them, the rotating ring is clamped and connected with the movable end of the lifting member 83, and the rotating ring is rotatably connected inside the positioning ring. Four blocking disks 85 are equidistantly rotatably connected to the outside of the positioning ring of the rotating sleeve 84. A convex ring is welded inside the blocking disk 85, and a fitting groove is opened at the position corresponding to the outside of the convex ring on the outside of the positioning ring. A connecting bar 86 is welded to one end face of the blocking disk 85 close to the atomizing structure 11. The connecting bar 86 is located inside the rectangular groove. A flow dividing cover 87 is welded to the outside of the connecting bar 86. The flow dividing cover 87 is sleeved outside the partition cover 74. A groove is opened inside the flow dividing cover 87, and the connecting bar 86 is connected inside the groove. Multiple notches 88 are opened on the outside of the flow dividing cover 87, and multiple notches 88 are all staggered with the rectangular groove.

[0074] In the present invention, the lifting member 83 belongs to a linear driving structure, specifically an electric telescopic rod.

[0075] As Figure 7 and Figure 8As shown in the figure, the number of metal rotors 91 is set to four in total. The metal rotor 91 close to the atomization structure 11 is fixedly connected to the rotating column 104. Limiting strips 93 are arranged on the outer sides of the other three metal rotors 91, and the limiting strips 93 are connected to the rotating column 104. Guide grooves 94 are opened on the outer side of the positioning ring of the rotating sleeve 84 corresponding to the outer sides of the limiting strips 93. The rotating sleeve 84 is composed of a rotating ring and a positioning ring, so that the rotating ring and the positioning ring can rotate relative to each other without displacement. At this time, under the rotation of the rotating column 104, the positioning ring of the rotating sleeve 84 is driven to rotate through the limiting strip 93, so that the metal rotor 91 rotates. And under the action of the guide groove 94, when the lifting member 83 drives the rotating sleeve 84 to move along the axial direction of the rotating column 104, at this time, the rotating sleeve 84 moves on the outer side of the limiting strip 93 through the guide groove 94. Similarly, since the blocking disc 85 is rotatably connected to the outer side of the rotating column 104, at this time, the connecting strip 86 is inside the rectangular groove. At this time, the connecting strip 86 is limited by the partition cover 74, and the connecting strip 86 limits the blocking disc 85, so that the blocking disc 85 can move circumferentially along the outer side of the rotating column 104 without rotating. And under the action of the convex ring and the fitting groove, the rotation of the rotating column 104 and the rotating sleeve 84 is not restricted, ensuring that the rotation and movement between the rotating sleeve 84 and the rotating column 104 do not interfere with each other.

[0076] As Figures 3 to 7 shown, the support structure includes: a disc 71, air holes 72, a solid disc 73 and a partition cover 74; the disc 71 is connected to the circular tube 6, and the number of discs 71 is set to four in total, and the four discs 71 are arranged vertically at equal intervals along the horizontal plane; the air holes 72 are arranged on the disc 71 and are arranged in a circle around the center point of the disc 71; the solid disc 73 is connected to the middle of the disc 71, and a hollow interlayer is arranged inside the solid disc 73; the partition cover 74 is connected to one end of the solid disc 73 and is used for diverting gas.

[0077] In order to facilitate the diversion of gas so that the gases do not interfere with each other, at this time, under the action of the support structure, not only the filter screen 76 is supported, but also the gas can flow through the middle of the filter screen 76 or along the outer side of the filter screen 76.

[0078] Specifically, a plurality of air holes 72 are opened on one end face of the disc 71, the disc 71 is fixedly connected to the solid disc 73, the partition cover 74 is welded to the outer side of the solid disc 73, a plurality of holes are arranged inside the solid disc 73, one end face of the solid disc 73 is welded to the heat conducting column 75, rectangular grooves are symmetrically opened on the outer side of the partition cover 74, circular holes are opened at the center points of the solid disc 73 and the filter screen 76, holes are opened in the middle of the partition cover 74, an inclined angle is opened at the edge of one end of the partition cover 74 close to the fan blade 5, a hollow interlayer is arranged in the middle of the solid disc 73, and the metal rotor 91 and the metal stator 92 are both located inside the hollow interlayer.

[0079] As Figure 7 , Figure 8 and Figure 9 shown, four brushes 89 are clamped and installed on the outer side of the rotating sleeve 84. The brushes 89 are in contact with one end face of the barrier disc 85. Specifically, the brushes 89 are installed on the outside of the positioning ring of the rotating sleeve 84. There are two groups of barrier discs 85. One group is between the two barrier discs 85. The rotating sleeve 84 and the brushes 89 close to the mounting block 102 are the first ones. Starting from the mounting block 102 and moving towards the atomizing structure 11, the rotating sleeves 84 and the brushes 89 are the first, second, third, and fourth respectively. Among them, the first rotating sleeve 84 and the third rotating sleeve 84 are in one group, and the second rotating sleeve 84 and the fourth rotating sleeve 84 are in one group. Among them, the brushes 89 are all in contact with the filter net 76.

[0080] The present invention provides a method for using the above-mentioned blasting smoke and dust elimination device, including the following steps:

[0081] Step 1: Use the vehicle frame 1 to transport the entire blasting smoke and dust elimination device to the blasting operation site;

[0082] Step 2: Start the driving member 4. The driving member rotates at a high speed to drive the fan blade 5 to rotate synchronously, forming an air flow inside the conical cylinder 3. The air flow blows towards the blasting smoke and dust area along the axis of the conical cylinder 3;

[0083] Step 3: After the water source stored in the water tank 12 is processed by the atomizing structure 11, it is converted into water mist. At this time, the air flow generated by the driving member carries the atomized water droplets and covers the blasting smoke and dust area in a spraying manner;

[0084] Step 4: After the gas containing adsorbed smoke and dust enters the heating and filtering assembly, it is shunted by means of the staggered shunting structure. The gas is distributed to the two groups of filter nets 76 for filtering. The other two groups of filter nets 76 are heated and dried under the action of the heat generated by the rotation between the metal rotor 91 and the metal stator 92. Finally, the purified gas re-enters the middle of the atomizing structure 11 along the conical cylinder 3 and is mixed with the water mist. At the same time, the filter nets 76 are used alternately to realize filtering by the heated filter nets 76 and heating and drying of the filtered filter nets 76.

[0085] Working principle: The staff transports the blasting smoke and dust elimination device to the pre-selected working position through the vehicle frame 1. Subsequently, the direction and angle of the conical cylinder 3 are adjusted. Then, the water inlet end of the water pump is connected to the valve of the water tank 12 through a pipeline, and the water outlet end is connected to the atomizing structure 11. After opening the valve and the water pump, the water pump operates to extract the water in the water tank 12, transports it through the pipeline to the inside of the atomizing structure 11, and flows into the nozzle along the metal ring of the atomizing structure 11, and finally sprays out in the form of a misty liquid.

[0086] Meanwhile, the driving member 4 starts and drives the fan blade 5 to rotate. The rotation of the fan blade 5 generates negative pressure, adsorbing the dust-containing gas in the outside world into the inside of the conical cylinder 3. The gas flows along the heating and filtering assembly in the conical cylinder 3, mixes with the water mist sprayed by the nozzle, and is then driven by the gas to spray the water mist to the blasting position.

[0087] When the driving member 4 rotates, it drives the mounting block 102 to rotate synchronously through the mounting cover 101. The mounting block 102 then drives the rotating column 104 to rotate. The rotating column 104 drives the four metal rotors 91 to rotate synchronously. Since the metal stator 92 is fixed in the hollow interlayer of the solid disk 73, the gas between the metal rotor 91 and the metal stator 92 generates heat due to friction when the metal rotor 91 rotates. The heat is conducted to the filter screen 76 through the heat conducting column 75, uniformly heating the four filter screens 76 to keep them in a dry state, avoiding dust accumulation and blockage caused by the infiltration of water mist.

[0088] When the rotating column 104 rotates, it drives the limiting strip 93 to rotate (as Figure 8 shown). Under the action of the positioning ring, the limiting strip 93 can drive the rotating sleeve 84 to move axially along the rotating column 104. During this process, since the partition cover 74 remains fixed, at this time, the partition cover 74 limits the connecting strip 86 through the rectangular groove, so that the connecting strip 86 moves along the inside of the rectangular groove and cannot rotate. At this time, the connecting strip 86 and the blocking disk 85 can only move and cannot rotate, keeping themselves stationary. Then, after the lifting member 83 is started, the blocking disk 85 moves along the outside of the rotating column 104. Under the action of the guiding groove 94 and the rectangular groove, when the rotating sleeve 84 moves axially, it slides outside the limiting strip 93 through the guiding groove 94 and drives the connecting strip 86 to move in the rectangular groove through the blocking disk 85. Finally, the four flow dividing covers 87 and the blocking disk 85 act synchronously in the following state:

[0089] The notch 88 of the first flow dividing cover 87 fits against the outside of the partition cover 74, and the notch 88 of the second flow dividing cover 87 separates from the outside of the partition cover 74.

[0090] The notch 88 of the third flow dividing cover 87 fits against the outside of the partition cover 74, and the notch 88 of the fourth flow dividing cover 87 separates from the outside of the partition cover 74.

[0091] The first and third blocking disks 85 separate from the holes in the middle of the partition cover 74, and the second and fourth blocking disks 85 coincide with the holes in the middle of the partition cover 74.

[0092] At this time, the gas flow path is as follows: entering from the hole of the first partition cover 74 to the surface of the filter net 76, penetrating the filter net 76 and then entering the inside of the solid disk 73, and then flowing into the outside of the second partition cover 74. Since the hole of the second partition cover 74 is blocked by the blocking disk 85, the gas is forced to enter the air-permeable holes 72 of the disk 71 from the notch 88 of the shunt cover 87, and then flows into the outside of the third partition cover 74. Similarly, due to the blockage of the notch 88 of the third partition cover 74, the gas can only enter the surface of the filter net 76 through the hole of the third partition cover 74, penetrate and then flow through the solid disk 73 into the outside of the fourth partition cover 74, and then enter the conical cylinder 3 through the air-permeable holes 72 of the fourth disk 71, and finally be discharged from one end of the atomization structure 11. At this time, two of the filter nets 76 are not blown by the gas, resulting in a rapid temperature rise inside the filter net 76, and then the filter net 76 is rapidly dried, forming an alternating partition drying among the four filter nets 76, improving the drying efficiency without hindering the gas flow;

[0093] In addition, part of the gas driven by the rotation of the fan blade 5 enters the air-permeable holes 72 of the disk 71 and the outside of the second partition cover 74 through the notch 88 of the second shunt cover 87. When the rotating sleeve 84 moves, its positioning ring drives the brush 89 to rotate, and the four brushes 89 respectively clean the surfaces of the four filter nets 76 to remove the intercepted dust, ensuring the continuous and efficient operation of the filter assembly.

[0094] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
