DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] This application provides a dust removal mechanism and a cement silo. Please refer to Figures 1 - 7 : including; Cylinder body 1; The cylinder body 1 is used for the cement body, and the upper end of the cylinder body 1 is sealed; Base 2; The base 2 is used to support the cylinder body 1; Upper cover 3; The upper cover 3 is installed at the upper end of the cylinder body 1, and a conical cavity 4 is formed between the upper cover 3 and the cylinder body 1; Gas collection hood 5; A gas collection pipeline 6 is provided on the gas collection hood 5; The gas collection pipeline 6 transmits the dust gas 78 from the inside of the cylinder body 1 to the conical cavity 4; Dust removal component 7; the dust removal component 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.

[0022] Specifically, in actual application, the upper cover 3 covers the upper end of the cylinder body 1, and a cavity is formed between the upper cover 3 and the cylinder body 1. The dust removal mechanism is arranged in this cavity; the water tank 71 is used to hold the water body 72; The air collecting hood 5 can concentrate 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. Through the action of the dust removal component 7, the dust gas 78 can be dust-removed. Through the action of inserting the inverted cone 73 into the water body 72, the dust gas 78 can be input to the bottom position 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 comes into contact with the water body 72, and the dust gas 78 adheres to the inner wall of the bubble, thus achieving the purpose of dust removal; Under the action of the buoyancy of the bubbles, the bubbles drive the dust gas 78 to move upward. 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.

[0023] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the dust removal component 7 further includes; A ventilation hole 76, which is opened at the central position of the inverted cone 73; A bracket 77, which is arranged at the bottom of the water tank 71 and is used to support the inverted cone 73; The spiral cone plate 74 is installed on the lower surface of the inverted cone 73, and the spiral cavity 75 shows a spiral upward trend; one end of the spiral cavity 75 is arranged at the position of the gas collecting pipeline 6, and the other end of the spiral cavity 75 is communicated with the conical cavity 4; The water body 72 generates buoyancy on the dust gas 78 entering the spiral cavity 75. The dust gas 78 forms bubbles and clings to the spiral cone plate 74 and the inverted cone 73, and the dust gas 78 adheres to the inner wall of the bubble.

[0024] Specifically, in actual application, the inverted cone 73 is a cone with a wider upper part and a narrower lower part. 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 ventilation hole 76 is located at the lower end of the inverted cone 73, and the ventilation hole 76 is communicated with the gas collecting pipeline 6; The bracket 77 is used to support the inverted cone 73, and the inverted cone 73 is in a stable state. The spiral cavity 75 shows a spiral upward trend, making the spiral cavity 75 in a spiral upward spatial form. Under the action of the buoyancy of the bubbles, the bubbles drive the dust gas 78 to move upward. 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.

[0025] Refer to Figures 1 - 6 , the gas collecting pipeline 6 includes a first pipeline 61 installed on the gas collecting hood 5. The gas collecting hood 5 is fixedly connected to the cylinder body 1. The upper end of the first pipeline 61 is open and higher than the liquid level of the water body 72. The first pipeline 61 passes through the upper end of the cylinder body 1. A fan 62 is provided in the first pipeline 61. When the fan 62 is not working, the gas collecting hood 5 and the ventilation hole 76 can be communicated. A check valve 63 is installed at the lower end of the first pipeline 61, and a ventilation component 64 is provided between the first pipeline 61 and the ventilation hole 76.

[0026] Specifically, in actual application, the first pipeline 61 penetrates through the upper end of the cylinder body 1. Through the setting that the upper end of the first pipeline 61 is open and higher than the liquid level of the water body 72, the backflow of the water body 72 into the first pipeline 61 can be avoided. The fan 62 can actively transport the dust gas 78 in the cylinder body 1 to the dust removal component 7 at a certain pressure; Through the setting that the gas collecting hood 5 and the ventilation hole 76 can be communicated when the fan 62 is not working, when the fan 62 fails, due to the pressure generated by the self-feeding of the cylinder body 1, the dust gas 78 is passively transported to the dust removal component 7 at the pressure inside the cylinder body 1. Through the function of the check valve 63, the evaporated water of 72 can be prevented from flowing back into the cylinder body 1, preventing the cement from getting damp and caking.

[0027] Refer to Figure 1 and Figure 3 , Embodiment 1 of the ventilation component 64. The ventilation component 64 includes a plurality of L-shaped gas pipelines 641 between the ventilation hole 76 and the gas collecting pipeline 6. One end of the L-shaped gas pipeline 641 is communicated with the first pipeline 61, and the other end is communicated with the ventilation hole 76.

[0028] Specifically, in actual application, the dust gas 78 in the first pipeline 61 is shunted into each ventilation hole 76 through the L-shaped gas pipeline 641, discharged from the ventilation hole 76 and contacts with the water body 72.

[0029] Refer to 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 first pipeline 61 passes through the channel 642. An air deflector 643 is provided on the ventilation hole 76. The air deflector 643 turns the dust gas 78 in the gas collecting pipeline 6 by 180 degrees and transports it to the ventilation hole 76, entering the spiral cavity 75. An airtight cavity 645 is formed between the air deflector 643, the first pipeline 61, and the inverted cone 73 for the dust gas 78 to flow through.

[0030] Specifically in practical applications, the dust gas 78 in the first pipeline 61 can be redirected by the air inversion hood 643. The dust gas 78 that was originally flowing upward is turned 180 degrees to flow downward until it contacts the conical cavity 4, forming bubbles, which facilitates the attachment of the dust gas 78. Through the function of the airtight cavity 645, the leakage of the dust gas 78 into the water body 72 can be prevented. Under the air pressure of the dust gas 78, the liquid level in the air inversion hood 643 should be lower than the liquid level in the water tank 71.

[0031] Refer to Figure 1 and Figure 4 , for the first embodiment of the inverted cone 73, there are multiple inverted cones 73.

[0032] Specifically in practical applications, when the number of inverted cones 73 is set to 3, the dust removal efficiency per unit time can be improved. The flow rate of the dust gas 78 per unit time is relatively large, but it will waste the area of the upper surface of the cylinder 1. Both the cylinder 1 and the inverted cone 73 are circular, and only 3 - 4 inverted cones 73 can be arranged simultaneously. In this embodiment, there are three inverted cones 73.

[0033] Refer to Figure 5 and Figure 6 , for the second embodiment of the inverted cone 73, there is one inverted cone 73.

[0034] Specifically in practical applications, having one inverted cone 73 can maximize the utilization of the space on the upper surface of the cylinder 1, but with only one inverted cone 73, the flow rate of the dust gas 78 per unit time is relatively small.

[0035] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , an exhaust hole 31 is installed at the upper end of the upper cover 3, a rain shield 32 is installed on the exhaust hole 31, a water tank 71 is provided with a circulation pipeline 712, and a bubbler 761 is installed on the ventilation hole 76.

[0036] Specifically in practical applications, through the function of the exhaust hole 31, the filtered dust gas 78 can be released into the atmosphere. Through the function of the rain shield 32, rainwater can be prevented from falling into the water tank 71. Through the function of the circulation pipeline 712, the water body 72 containing the dust gas 78 in the water tank 71 can be automatically circulated out for secondary filtration to improve the filtration effect of the water body 72. Through the function of the bubbler 761, the dust gas 78 can actively form bubbles.

[0037] For the first embodiment, refer to Figure 6 , a waterproof motor 731 is installed on the inverted cone 73, and a stirring rod 732 is installed at the rotating end of the waterproof motor 731. The stirring rod 732 is located in the spiral cavity 75.

[0038] Specifically, in actual applications, the rotation of the waterproof motor 731 can actively drive the rotation of the stirring rod 732. The stirring rod 732 breaks the bubbles formed by the flowing dust gas 78 into multiple tiny bubbles. During this process, the dust gas 78 can come into contact with more water body 72, increasing the contact area with the water body 72 and improving the dust removal efficiency.

[0039] Example 2. Refer to Figure 3 and Figure 7 , a first rod 733 is installed on the lower surface of the inverted cone 73. There are multiple first rods 733 and they are arranged staggeredly. Spikes 734 are provided on the surface of the first rod 733, and there are multiple spikes 734.

[0040] Specifically, in actual applications, through the action of the spikes 734, the bubbles formed by the dust gas 78 can be passively punctured to form multiple small bubbles. The dust gas 78 can come into contact with more water body 72, increasing the contact area with the water body 72 and improving the dust removal efficiency.
