[0045] Upper cover 3; the upper cover 3 is mounted on the upper end of the cylinder 1, and a conical cavity 4 is formed between the upper cover 3 and the cylinder 1;

[0046] A gas collecting hood 5 is provided with a gas collecting pipe 6 on the gas collecting hood 5; the gas collecting pipe 6 transmits the dust gas 78 from the cylinder 1 to the conical cavity 4;

[0047] Dust removal assembly 7; the dust removal assembly 7 includes a water tank 71, a water body 72, an inverted cone 73, and a spiral cone plate 74. The inverted cone 73 is inserted into the water body 72, and a spiral cavity 75 is formed between the spiral cone plate 74 and the inverted cone 73. The dust gas 78 moves upward along the spiral cavity 75.

[0048] Specifically in practical applications, the upper cover 3 is covered on the upper end of the cylinder 1, and a cavity is formed between the upper cover 3 and the cylinder 1, and the dust removal mechanism is arranged in the cavity; the water tank 71 is used to hold water 72;

[0049] The gas collecting hood 5 can collect the gas to the position of the gas collecting pipeline 6. The gas collecting pipeline 6 can actively or passively transport the dust gas 78 to the position of the dust removal component 7. The dust removal component 7 can remove dust from the dust gas 78. The inverted cone 73 is inserted into the water body 72 to input the dust gas 78 to the position at the bottom of the water body 72. The dust gas 78 forms bubbles at the bottom of the water body 72. At this time, the dust gas 78 contacts the water body 72 and adheres to the inner wall of the bubble, thereby achieving the purpose of dust removal.

[0050] Under the action of the bubble buoyancy, the bubbles drive the dust gas 78 to move upward, and through the obstruction of the spiral cone plate 74, as many bubbles as possible move along the spiral cavity 75, extending the moving path of the dust gas 78 and improving the dust removal effect.

[0051] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the dust removal component 7 also includes;

[0052] The vent hole 76 is opened at the center of the inverted cone 73;

[0053] Bracket 77, bracket 77 is provided at the bottom of the water tank 71, and is used to support the inverted cone 73;

[0054] The spiral cone plate 74 is mounted on the lower surface of the inverted cone 73, and the spiral cavity 75 is spirally ascending. One end of the spiral cavity 75 is located at the position of the gas collecting pipe 6, and the other end of the spiral cavity 75 is connected to the conical cavity 4.

[0055] The water body 72 generates buoyancy for the dust gas 78 entering the spiral cavity 75 , and the dust gas 78 forms bubbles and adheres closely to the spiral cone plate 74 and the inverted cone 73 , and the dust gas 78 adheres to the inner wall of the bubble.

[0056] Specifically, in actual application, the inverted cone 73 is a cone that is wide at the top and narrow at the bottom. The upper end of the water body 72 does not submerge the upper end of the inverted cone 73 and is inserted upside down in the water body 72. The vent 76 is located at the lower end of the inverted cone 73, and the vent 76 is connected to the gas collecting pipe 6.

[0057] The bracket 77 is used to support the inverted cone 73. The inverted cone 73 is in a stable state, and the spiral cavity 75 has a spiral upward trend, so that the spiral cavity 75 is in a spiral upward spatial form.

[0058] Under the action of the bubble buoyancy, the bubbles drive the dust gas 78 to move upward, and through the obstruction of the spiral cone plate 74, as many bubbles as possible move along the spiral cavity 75, extending the moving path of the dust gas 78 and improving the dust removal effect.

[0059] Reference Figures 1-6 The gas collecting pipeline 6 includes a first pipe 61 installed on the gas collecting hood 5. The gas collecting hood 5 is fixedly connected to the cylinder 1. The upper end of the first pipe 61 is open and higher than the liquid level of the water body 72. The first pipe 61 passes through the upper end of the cylinder 1. A fan 62 is provided in the first pipe 61. When the fan 62 is not working, it can connect the gas collecting hood 5 and the vent 76. A one-way valve 63 is installed at the lower end of the first pipe 61, and a ventilation component 64 is provided between the first pipe 61 and the vent 76.

[0060] Specifically, in practical applications, the first pipe 61 passes through the upper end of the cylinder 1. By setting the upper end opening of the first pipe 61 higher than the liquid level of the water body 72, it is possible to prevent the water body 72 from flowing back into the first pipe 61. The fan 62 can actively transport the dust gas 78 in the cylinder 1 to the dust removal component 7 at a certain pressure.

[0061] The setting of the air collecting hood 5 and the air vent 76 can be connected when the fan 62 is not working. When the fan 62 fails, the pressure generated by the feeding of the cylinder 1 itself will passively transport the dust gas 78 to the dust removal component 7 at the pressure inside the cylinder 1. The one-way valve 63 can prevent the evaporated water from 72 from flowing back into the cylinder 1, thereby preventing the cement from getting damp and hardening.

[0062] Reference Figure 1 and Figure 3In the first embodiment of the ventilation component 64, the ventilation component 64 includes an L-shaped gas pipe 641 between the vent hole 76 and the gas collecting pipeline 6. The L-shaped gas pipe 641 is provided with multiple ones. One end of the L-shaped gas pipe 641 is connected to the first pipeline 61, and the other end is connected to the vent hole 76.

[0063] Specifically, in actual application, the dust gas 78 in the first pipeline 61 is diverted to each vent hole 76 through the L-shaped gas pipe 641 , and is discharged from the vent hole 76 and contacts the water body 72 .

[0064] Reference Figure 5 and Figure 6 , embodiment 2 of the ventilation component 64, the ventilation component 64 includes a channel 642 provided at the center of the water tank 71, the channel 642 is for the first pipe 61 to pass through, and an inverted air cover 643 is provided on the vent hole 76. The inverted air cover 643 turns the dust gas 78 in the gas collecting pipe 6 180 degrees and transports it to the vent hole 76, and enters the spiral cavity 75. An airtight cavity 645 is formed between the inverted air cover 643, the first pipe 61, and the inverted cone 73 for the dust gas 78 to circulate.

[0065] Specifically, in actual application, the dust gas 78 in the first pipe 61 is deflected by the reverse air cover 643, which can turn the dust gas 78, which originally flows upward, 180 degrees and flow downward until it contacts the conical cavity 4, forming bubbles, which facilitate the adhesion of the dust gas 78. The airtight cavity 645 can prevent the dust gas 78 from leaking into the water body 72.

[0066] Under the pressure of the dust gas 78 , the liquid level in the inverted air hood 643 should be lower than the liquid level in the water tank 71 .

[0067] Reference Figure 1 and Figure 4 In the first embodiment of the inverted cone 73 , a plurality of inverted cones 73 are provided.

[0068] Specifically in practical applications, setting the inverted cones 73 to three can improve the dust removal efficiency per unit time, and the flow rate of the dust gas 78 per unit time is larger, but it will waste the area of ​​the upper surface of the cylinder 1. The cylinder 1 and the inverted cones 73 are both circular, and only 3-4 inverted cones 73 can be arranged at the same time. In this embodiment, there are three inverted cones 73.

[0069] Reference Figure 5 and Figure 6 , embodiment 2 of the inverted cone 73, the inverted cone 73 is provided with a.

[0070] Specifically in practical applications, the inverted cone 73 is provided to maximize the use of the space on the upper surface of the cylinder 1 , but there is only one inverted cone 73 , and the flow rate of the dust gas 78 per unit time is relatively small.

[0072] Specifically in actual applications, the filtered dust gas 78 can be released into the atmosphere through the exhaust hole 31, and the rain cover 32 can prevent rainwater from falling into the water tank 71. The water body 72 containing dust gas 78 in the water tank 71 can be automatically circulated out through the circulation pipeline 712, and then subjected to secondary filtration to improve the filtering effect of the water body 72; the dust gas 78 is actively formed into bubbles through the bubbler 761.

[0073] Example 1, refer to Figure 6 A waterproof motor 731 is installed on the inverted cone 73 , and a stirring rod 732 is installed on the rotating end of the waterproof motor 731 , and the stirring rod 732 is located in the spiral cavity 75 .

[0074] Specifically in actual applications, the rotation of the waterproof motor 731 can actively drive the stirring rod 732 to rotate. The stirring rod 732 breaks the bubbles formed by the dust gas 78 flowing through, forming multiple tiny bubbles. In this process, the dust gas 78 can come into contact with more water bodies 72, increasing the contact area with the water body 72 and improving the dust removal efficiency.
