[0017] Ventilation holes are provided on the disk and arranged in a circular pattern around the center point of the disk;

[0018] A solid disk is connected to the middle of the circular disk, and a hollow interlayer is provided inside the solid disk;

[0037] The present invention also provides a method of using the above-mentioned explosion smoke elimination device, comprising the following steps:

[0038] Step 1: Transport the blasting smoke and dust elimination device as a whole to the blasting operation site using a vehicle frame;

[0039] Step 2: Start the drive unit. The drive unit rotates the fan blades synchronously, forming an airflow inside the cone. The airflow blows along the cone axis toward the blasting smoke and dust area.

Finally, the purified gas re-enters the middle of the atomizing structure along the cone and mixes with the water mist. At the same time, the filter screens are used alternately to achieve filtration by the heated filter screens and then heated and dried.

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

[0043] (1) This device uses a heated filter assembly. The metal rotor and metal stator generate heat through friction, which is transferred to the filter screen through the heat conduction column to keep it dry and prevent dust from adhering and accumulating due to moisture. With the staggered flow distribution structure, two sets of filter screens can work alternately. While one set is filtering, the other set is heated and dried to avoid the filter screen from being continuously damp. This not only ensures the stability of the filtration effect, but also reduces the corrosion and aging of the filter screen due to moisture, greatly extends the service life of the filter screen, and reduces maintenance costs and frequency.

[0044] (2) This device drives the fan blades to rotate at high speed through the drive component, forming a strong negative pressure airflow in the cone, which can actively adsorb smoke and dust from a distance and introduce the dust-laden gas into the device. At the same time, the atomization structure and the heating and filtration components work together to first capture large dust particles with water mist, and then intercept fine particles through the filter screen. Even when faced with high concentrations of smoke and dust, it can achieve efficient purification, significantly improve dust removal efficiency, and effectively solve the problem of insufficient capture capacity of traditional systems for long-distance, high-concentration smoke and dust.

Water tank. Detailed Implementation

[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] Example 1: This invention provides a device for eliminating blasting smoke and dust, such as... Figures 1 to 12 As shown, the device includes: a frame 1, a rotating frame 2, a cone 3, a drive unit 4, fan blades 5, a water tank 12, and a heating and filtering assembly. The frame 1 supports the entire blasting smoke 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 cone 3 is connected to the rotating frame 2. The drive unit 4 is connected inside the cone 3. The fan blades 5 are connected to the output shaft of the drive unit 4, and the drive unit 4 drives the gas to flow through the fan blades 5. The heating and filtering assembly includes: a circular tube 6, a support structure, a heat-conducting column 75, a filter screen 76, an interleaved flow distribution structure, a metal rotor 91, a metal stator 92, and a connecting structure. The circular tube 6 is connected inside the cone 3, the support structure is connected inside the circular tube 6, the heat-conducting column 75 is connected to the support structure, the filter screen 76 is sleeved on the outside of the heat-conducting column 75, the interleaved flow distribution structure is connected to the outside of the support structure, the metal rotor 91 is connected inside the support structure, the metal stator 92 is sleeved on the outside of the metal rotor 91, and the connecting structure is connected to the middle of the circular tube 6.

[0060] During blasting operations, spray dust suppression increases the air moisture content, causing the filter screen 76 to become damp. This leads to dust accumulation and blockage of the filter screen pores, reducing the filtration effect. This invention keeps the filter screen 76 dry by heating the filter component. This not only prevents dust from adhering and accumulating due to moisture, maintaining smooth airflow and high-efficiency filtration performance, but also reduces corrosion and aging of the filter screen 76 due to moisture, extending its service life and reducing maintenance costs. In addition, in a dry state, the filter screen 76 can use the principle of thermal expansion and contraction to cause particles to fall off. Combined with the staggered flow distribution structure, it realizes the alternating cycle of filtration and cleaning, ensuring the continuous and stable operation of the device and significantly improving the overall dust removal efficiency.

[0061] In use, the device is transported to a predetermined location via the frame 1. The position of the device can be flexibly adjusted using the rollers at the bottom of the frame 1. Then, the drive motor inside the frame 1 is started, driving the rotating frame 2 to swing the cone 3 along the horizontal plane (X-axis) to the predetermined position. Next, the angle of the cone 3 along the vertical plane (Y-axis) is adjusted by the electric lifting rod between the bottom end of the cone 3 and the top end of the rotating frame 2, so that the angle with the ground reaches the predetermined angle and is fixed. Then, the drive component 4 (specifically a stepper motor) is started. When the drive component 4 runs, it drives the fan blade 5 to rotate. When the fan blade 5 rotates, the gas moves along the middle of the cone 3 (axial movement), and the gas moving along the inside of the cone 3... Upon entering the staggered flow distribution structure, the gas is evenly distributed to two of the filter screens 76 for filtration, while the other two filter screens 76 are temporarily not involved in filtration. At the same time, the metal rotor 91 rotates synchronously with the drive shaft of the drive component 4 through the connecting structure. Meanwhile, 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 viscosity. The heat enters the interior of the filter screen 76 through the heat conduction column 75, heating different locations inside the filter screen 76, thereby keeping the filter screen 76 dry. Furthermore, the filter screen 76 is fixed by the support structure.

[0062] Specifically, four rollers are installed at the bottom of the frame 1, and a frame is welded to the top edge of the frame 1. A water tank 12 is located inside the frame, and a valve is embedded at one end of the water tank 12 to control the water flow. A drive motor is installed inside the frame 1, and the output shaft of the drive motor is connected to a rotating frame 2 via a key. The rotating frame 2 is fitted inside the frame 1 and is rotatably connected to the frame 1. Rotating rods are symmetrically connected inside the rotating frame 2 via bearings. A cone 3 is fixedly installed between the two rotating rods. An atomizing structure 11 is installed at the end of the cone 3 closest to its smallest diameter. A water pump is installed inside the frame 1 on one side of the drive motor. The water pump's inlet is connected via pipes and valves, and its outlet is connected to the atomizing structure 11. The atomizing structure 11 is composed of a metal ring and nozzles. Water flows evenly into multiple nozzles along the inside of the metal ring, transporting water from the water tank 12 to the atomizing structure 11. After being evenly distributed by the metal ring, the water is sprayed out as a mist from the nozzles. An electric lifting rod is rotatably connected between the bottom of the cone 3 and the top of the rotating frame 2. The electric lifting rod between the cone 3 and the rotating frame 2 can adjust the pitch angle of the cone 3 to meet the needs of different operating scenarios (the above structures are all existing technologies and will not be elaborated on here).

[0063] Inside the cone 3, near the end with the maximum diameter, a drive component 4 is installed. A fan blade 5 is mounted on the outside of the output shaft of the drive component 4 via a flat key. Inside the cone 3, near the fan blade 5, a circular tube 6 is installed. Inside the circular tube 6, a support structure is installed. The number of support structures is set to four (e.g., ...). Figure 7 As shown), heat-conducting columns 75 are installed at equal intervals inside the four support structures. A filter screen 76 is sleeved on the outside of the heat-conducting columns 75. An interleaved flow-diverting structure is installed on one end face of each of the four support structures. A metal rotor 91 is rotatably connected inside each of the four support structures. A metal stator 92 is provided on the outside of the metal rotor 91. A connecting structure is installed on one end of the output shaft of the drive component 4.

[0064] In this invention, the driving component 4 is a structure that drives the object to rotate, specifically a stepper motor.

[0065] To facilitate the installation and disassembly of the circular tube 6, an arc-shaped block is welded to the back of the circular tube 6. A fixing bolt is threaded through the inside of the arc-shaped block. The fixing bolt and the cone 3 are connected by threads, and the circular tube 6 and the cone 3 are fixed by the fixing bolt. In order to facilitate the dumping of impurities filtered inside the circular tube 6, a discharge trough is opened at the lowest point of the outer surface of the circular tube 6. A barrier cover is installed on the outside of the circular tube 6 inside the discharge trough by screws. The barrier cover blocks the discharge trough to prevent dust from entering the inside of the circular tube 6 along the discharge trough during the filtration process. The barrier cover also facilitates the cleaning of dirt filtered inside the circular tube 6.

[0066] like Figure 2 and Figure 10As shown, the connection 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 drive component 4; the mounting block 102 is inserted into the mounting cover 101; the bolt 103 is inserted into the mounting block 102 and the mounting cover 101; and the rotating column 104 is connected to the mounting block 102.

[0067] Since it is necessary to drive the metal rotor 91 to rotate, a connecting structure is used to connect the metal rotor 91 and the driving component 4 so that the driving component 4 can drive the metal rotor 91 to rotate during rotation. The metal rotor 91 is made of copper and the metal stator 92 is made of iron. When the two rotate together, the metal rotor 91 drives the gas to flow along the inner side of the metal stator 92, and heat is generated due to friction.

[0068] In use, insert the mounting block 102 into the mounting cover 101, and then pass the bolt 103 through the mounting cover 101 and the mounting block 102. This fixes the mounting cover 101 and the mounting block 102, thereby fixing the rotating column 104. After the rotating column 104 is fixed, the position of the round tube 6 is fixed by the support structure. Then, the round tube 6 is fixed to the cone 3.

[0069] Specifically, a mounting cover 101 is welded to one end of the output shaft of the drive component 4. A mounting block 102 is inserted inside the mounting cover 101. A bolt 103 is connected through the mounting block 102 and one end face of the mounting cover 101. The bolt 103 is composed of a screw and a nut. The screw passes through the mounting block 102 and the mounting cover 101. The nut is threaded to the outside of the screw and located at the other end of the mounting cover 101, thereby fixing the rotating column 104. Then, the round tube 6 is fixed through the support structure. Finally, the round tube 6 is fixed to the cone 3. The rotating column 104 is rotatably connected to the inside of the solid disk 73. The metal rotor 91 and the metal stator 92 are made of copper and iron, respectively.

[0070] As a preferred embodiment of the above technical solution, the staggered diversion structure includes: a mounting rod 81, a connecting ring 82, a lifting component 83, a rotating sleeve 84, a baffle plate 85, a connecting strip 86, a diversion shroud 87, and a slot 88; the mounting rod 81 is connected to the circular pipe 6; the connecting ring 82 is connected to the mounting rod 81, and the mounting rod 81 supports the connecting ring 82 so that the center line of the connecting ring 82 coincides with the center line of the circular pipe 6; the lifting component 83 is connected to the connecting ring 82; the rotating sleeve 84 is connected to the lifting component 83, and the lifting component 83 drives the rotating sleeve 84 to move; the baffle plate 85 is connected to the rotating sleeve 84; the connecting strip 86 is connected to the baffle plate 85; the diversion shroud 87 is connected to the connecting strip 86; and the slot 88 is located on the outside of the diversion shroud 87.

[0071] Because the filter 76 contains gas with high moisture content, it becomes damp after use due to moisture interference, thus affecting its normal use. During this process, the filter 76 becomes unusable. At this point, a staggered flow-diverting structure is used to divert the gas, allowing some gas to enter some filters 76, while the remaining filters 76 remain in a dry environment, achieving the alternating use of the filters 76 (e.g., Figure 7 (As shown).

[0072] In use, the lifting component 83 drives the rotating sleeve 84 to move. As the rotating sleeve 84 moves, it drives the baffle plate 85 to move. The baffle plate 85, in turn, drives the flow divider 87 to move via the connecting strip 86. This causes the slot 88 of the flow divider 87 to be exposed on one side of the baffle 74. Simultaneously, the rectangular slot on the outside of the baffle 74 is blocked by the flow divider 87, and the baffle plate 85 enters the hole in the middle of the baffle 74. Since there are four flow dividers 87 and four baffle plates 85, they work together. At this time, the slot 88 of the first flow divider 87 is sealed against the outside of the baffle 74, while the slot 88 of the second flow divider 87... The slot 88 of the third diverter shroud 87 exposes the outside of the partition shroud 74, forming an open / closed state. The slot 88 of the third diverter shroud 87 is fitted against the outside of the partition shroud 74 to close the slot 88. The slot 88 of the fourth diverter shroud 87 exposes the outside of the partition shroud 74, forming an open / closed state. Simultaneously, the first baffle plate 85 separates from the hole in the middle of the partition shroud 74, the second baffle plate 85 enters into the hole in the middle of the partition shroud 74 and fits against it, the third baffle plate 85 separates from the hole in the middle of the partition shroud 74, the fourth baffle plate 85 enters into the hole in the middle of the partition shroud 74 and fits against it, and the rotating sleeve 84 causes multiple baffle plates 85 and multiple diverter shrouds 87 to move synchronously (e.g., ...). Figure 7 (As shown).

[0073] Four mounting rods 81 are arranged circumferentially inside the circular tube 6. A common connecting ring 82 is welded between the four mounting rods 81. A rotating sleeve 84 is embedded in the end face of the connecting ring 82 near the atomizing structure 11. The rotating sleeve 84 is composed of a rotating ring and a positioning ring. The rotating ring and the movable end of the lifting component 83 are snapped together. The rotating ring is rotatably connected inside the positioning ring. Four baffles 85 are equidistantly rotatably connected to the outside of the positioning ring of the rotating sleeve 84. A convex ring is welded inside the baffle 85. A matching groove is opened on the outside of the positioning ring corresponding to the outside of the convex ring. A connecting strip 86 is welded to the end face of the baffle 85 near the atomizing structure 11. The connecting strip 86 is located inside the rectangular groove. A flow divider 87 is welded to the outside of the connecting strip 86. The flow divider 87 is sleeved on the outside of the separator 74. A groove is opened inside the flow divider 87. The connecting strip 86 is connected inside the groove. Multiple slots 88 are opened on the outside of the flow divider 87. The multiple slots 88 are staggered with the rectangular groove.

[0074] In this invention, the lifting component 83 is a linear drive structure, specifically an electric telescopic rod.

[0075] like Figure 7 and Figure 8 As shown, there are four metal rotors 91. The metal rotor 91 closest to the atomizing structure 11 is fixedly connected to the rotating column 104. The other three metal rotors 91 are provided with limit strips 93 on their outer sides, which are connected to the rotating column 104. The outer side of the positioning ring of the rotating sleeve 84 is provided with a guide groove 94 corresponding to the outer side of the limit strip 93. The rotating sleeve 84 is composed of a rotating ring and a positioning ring, which allows the rotating ring and the positioning ring to 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 limit strip 93, thereby causing the metal rotors 91 to rotate. Under the action of the guide groove 94, the rotation of the rotating sleeve 84 is further enhanced. When the lifting component 83 drives the rotating sleeve 84 to move along the axial direction of the rotating column 104, the rotating sleeve 84 moves outside the limiting strip 93 through the guide groove 94. Similarly, since the blocking disk 85 is rotatably connected to the outside of the rotating column 104, 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 disk 85, so that the blocking disk 85 can move circumferentially along the outside of the rotating column 104 but cannot rotate. Furthermore, under the action of the convex ring and the fitting groove, the rotation of the rotating column 104 and the rotating sleeve 84 is unrestricted, ensuring that the rotation and movement between the rotating sleeve 84 and the rotating column 104 do not interfere with each other.

[0076] like Figures 3 to 7 As shown, the support structure includes: a disc 71, a vent 72, a solid disc 73, and a partition cover 74; the disc 71 is connected to the circular tube 6, and a total of four discs 71 are arranged vertically at equal intervals along the horizontal plane; the vent 72 is provided on the disc 71 and 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 provided inside the solid disc 73; the partition cover 74 is connected to one end of the solid disc 73 and is used to divert the gas.

[0077] In order to facilitate the diversion of gas and prevent mutual interference between gases, the supporting structure not only supports the filter screen 76, but also allows the gas to flow along the middle of the filter screen 76 or along the outer side of the filter screen 76.

[0078] Specifically, the disc 71 has multiple ventilation holes 72 on one end face, a solid disc 73 is fixedly connected to the disc 71, a partition cover 74 is welded to the outside of the solid disc 73, multiple holes are provided 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 provided on the outside of the partition cover 74, a round hole is provided at the center point of the solid disc 73 and the filter screen 76, a hole is provided in the middle of the partition cover 74, an inclined angle is provided on the edge of the partition cover 74 near the fan blade 5, a hollow sandwich is provided in the middle of the solid disc 73, and the metal rotor 91 and the metal stator 92 are both located inside the hollow sandwich.

[0079] like Figure 7 , Figure 8 and Figure 9 As shown, four brushes 89 are snapped onto the outside of the rotating sleeve 84. The brushes 89 are in contact with one end face of the baffle plate 85. Specifically, the brushes 89 are installed on the outside of the positioning ring of the rotating sleeve 84. There are two sets of baffle plates 85. The two baffle plates 85 are in one set. The rotating sleeve 84 and brushes 89 closest to the mounting block 102 are the first set. The rotating sleeves 84 and brushes 89 from the mounting block 102 toward the atomizing structure 11 are the first, second, third and fourth sets, respectively. The first rotating sleeve 84 and the third rotating sleeve 84 are in one set, and the second rotating sleeve 84 and the fourth rotating sleeve 84 are in another set. All the brushes 89 are in contact with the filter screen 76.

[0080] This invention provides a method for using the above-mentioned explosion smoke and dust elimination device, comprising the following steps:

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

[0082] Step 2: Start the drive unit 4. The drive unit rotates at high speed, driving the fan blades 5 to rotate synchronously, forming an airflow inside the cone 3. The airflow blows along the axis of the cone 3 towards the explosion smoke and dust area.

[0083] Step 3: The water stored in the water tank 12 is processed by the atomizing structure 11 and converted into water mist. At this time, the airflow generated by the driving component carries the atomized water droplets and sprays them to cover the explosion smoke and dust area.

[0084] Step 4: After the gas containing adsorbed dust enters the heated filter assembly, it is split by the staggered flow splitting structure. The gas is distributed to two sets of filter screens 76 for filtration. The other two sets of filter screens 76 are heated and dried by 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 cone 3 and mixes with water mist. At the same time, the filter screens 76 are used alternately to achieve filtration by the heated filter screens 76 and then heat-dry the filtered filter screens 76.

[0085] Working principle: The operator transports the blasting smoke and dust elimination device to the pre-selected work location via the vehicle frame 1. Then, the direction and angle of the cone 3 are adjusted. Next, the water pump's inlet is connected to the valve of the water tank 12 via a pipe, and the outlet is connected to the atomizing structure 11. After opening the valve and the water pump, the pump operates to draw water from the water tank 12, which is then transported through the pipe to the interior of the atomizing structure 11. The water flows along the metal ring of the atomizing structure 11 into the nozzle, and is finally sprayed out in the form of a mist.

[0086] At the same time, the drive unit 4 starts and drives the fan blade 5 to rotate. The rotation of the fan blade 5 generates negative pressure, which adsorbs the dust-containing gas from the outside and enters the inside of the cone 3. The gas flows along the heating and filtering components inside the cone 3 and mixes with the water mist sprayed from the nozzle. The gas then carries the water mist to the explosion position.

[0087] When the drive component 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 conduction column 75, which heats the four filter screens 76 evenly, keeping them dry and preventing dust accumulation and blockage due to water mist penetration.

[0088] When the rotating column 104 rotates, it drives the limit bar 93 to rotate (e.g. Figure 8 As shown), the positioning ring enables the limiting strip 93 to drive the rotating sleeve 84 to move axially along the rotating column 104. During this process, since the partition cover 74 remains fixed, the partition cover 74 limits the connecting strip 86 through the rectangular groove, preventing the connecting strip 86 from rotating as it moves along the inside of the rectangular groove. At this time, the connecting strip 86 and the baffle plate 85 can only move but cannot rotate, keeping them stationary. Then, after the lifting component 83 is activated, the baffle plate 85 moves along the outside of the rotating column 104. Under the action of the guide groove 94 and the rectangular groove, when the rotating sleeve 84 moves axially, it slides on the outside of the limiting strip 93 through the guide groove 94, and drives the connecting strip 86 to move within the rectangular groove through the baffle plate 85. Finally, the four diversion covers 87 and the baffle plate 85 move synchronously in the following states:

[0089] The slot 88 of the first diversion shroud 87 is attached to the outside of the partition shroud 74, and the slot 88 of the second diversion shroud 87 is separated from the outside of the partition shroud 74.

[0090] The slot 88 of the third diversion shroud 87 is attached to the outside of the partition shroud 74, and the slot 88 of the fourth diversion shroud 87 is separated from the outside of the partition shroud 74.

[0091] The first and third barrier plates 85 separate from the holes in the middle of the partition cover 74, while the second and fourth barrier plates 85 overlap with the holes in the middle of the partition cover 74.

[0092] At this time, the gas flow path is as follows: it enters the surface of the filter screen 76 through the hole of the first separator 74, penetrates the filter screen 76 and enters the interior of the solid disk 73, and then flows into the outside of the second separator 74. Since the hole of the second separator 74 is blocked by the blocking disk 85, the gas is forced to enter the vent hole 72 of the disk 71 through the slot 88 of the diverter 87, and then flows into the outside of the third separator 74. Similarly, since the slot 88 of the third separator 74 is blocked, the gas can only enter the surface of the filter screen 76 through the hole of the third separator 74, penetrates and flows into the outside of the fourth separator 74 through the solid disk 73, and then enters the cone 3 through the vent hole 72 of the fourth disk 71, and finally exits from one end of the atomizing structure 11. At this time, two of the filter screens 76 cannot be blown by the gas, resulting in rapid heating inside the filter screen 76, which in turn allows the filter screen 76 to dry rapidly. This results in staggered drying between the four filter screens 76, which improves the drying efficiency without hindering the flow of gas.

[0093] In addition, some of the gas driven by the rotation of the fan blade 5 enters the vent hole 72 of the disc 71 and the outside of the second partition cover 74 through the slot 88 of the second diverter shroud 87. When the rotating sleeve 84 moves, its positioning ring drives the brush 89 to rotate. The four brushes 89 clean the surfaces of the four filter screens 76 respectively, remove the trapped dust, and ensure that the filter assembly operates continuously and efficiently.

[0094] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
