[0033] For better dust removal effect, please refer to Figures 2 - 5 , where Figure 2 is the overall structural schematic diagram of a dust removal device provided by the present utility model, Figure 3 is the first dust removal structural schematic diagram of the dust removal area, Figure 4 is the schematic diagram of the first dust removal unit and the horizontal air flow channel, Figure 5 is the top view schematic diagram of the first dust removal structure, Figure 6 is the second dust removal structural schematic diagram of the dust removal area, Figure 7 is the top view schematic diagram of the second dust removal structure.
[0034] In one or more specific embodiments of the present utility model, the dust removal device 3 includes an upper part and a lower part of the dust removal device. The upper part of the dust removal device includes a dust removal device top cover 301, a front side plate 3021 of the upper part of the dust removal device, a rear side plate 3022 of the upper part of the dust removal device, a left side plate 3023 of the upper part of the dust removal device, and a right side plate 3024 of the upper part of the dust removal device. The dust removal device top cover 301 and the front side plate 3021 of the upper part of the dust removal device, the rear side plate 3022 of the upper part of the dust removal device, the left side plate 3023 of the upper part of the dust removal device, and the right side plate 3024 of the upper part of the dust removal device enclose an upper cavity 303. The lower part of the dust removal device includes four lower side plates 304 of the dust removal device and a bottom 305 of the dust removal device. The four lower side plates 304 of the dust removal device and the bottom 305 of the dust removal device enclose a lower cavity 306. A dust removal device dust outlet is provided on the bottom 305 of the dust removal device. The first pipe 2 is connected to the left side plate 3023 of the upper part of the dust removal device, and the second pipe 4 is connected to the right side plate 3024 of the upper part of the dust removal device. The upper cavity 303 is divided into an air inlet area 307, a dust removal area 309, and an air outlet area 308. The second pipe 4 communicates with the air outlet area 308, and the first pipe 2 communicates with the air inlet area 307. The dust removal area 309 is located between the air inlet area 307 and the air outlet area 308. A first dust removal structure is installed in the dust removal area 309. The first dust removal structure includes more than N first dust removal units 310. The first dust removal units 310 are arranged in sequence from front to back. A horizontal airflow channel 311 is formed between two adjacent first dust removal units 310. The top of each first dust removal unit 310 is detachably connected to the dust removal device top cover 301, and the front side of the first dust removal unit 310 is detachably connected to the front side plate 3021 of the upper part of the dust removal device. The Nth first dust removal unit 310 is detachably connected to the rear side plate 3022 of the upper part of the dust removal device, and N is a natural number greater than two.
[0035] Those skilled in the art should understand that the detachable connection can be achieved by a detachable connection with screws and nuts, or by other detachable methods. No special limitation is made here. As long as the first dust removal unit 310 can be fixed on the dust removal device top cover 301 and can also be detached from the dust removal device top cover 301, the first first dust removal unit 310, the first dust removal unit 310 can be fixed on the front side plate 3021 of the upper part of the dust removal device and can also be detached from the front side plate 3021 of the upper part of the dust removal device. The Nth first dust removal unit 310 can be fixed on the rear side plate 3022 of the upper part of the dust removal device and can also be detached from the rear side plate 3022 of the upper part of the dust removal device. Those skilled in the art can select a specific detachable method.
[0036] When the airflow with broken dust coming from the dust suction hood 1 enters the air inlet area, then enters the horizontal airflow channel 311, under the action of gravity, the broken dust falls into the lower cavity 306, and the gas continues to move forward and then enters the air outlet area 308, and then enters the second pipe 4 to achieve gas-solid separation.
[0037] In one or more specific embodiments of the present utility model, when N is 6, a better dust removal effect can be obtained.
[0038] To obtain a better separation effect, the center line of the first dust removal unit 310 is the center line 312 from left to right. The horizontal cross-section of the first dust removal unit 310 is centered on the center line 312 from left to right, and is alternately provided with a first peak 314 and a first valley 313. Through the setting of the first peak 314 and the first valley 313, the horizontal flow air passage 311 is a curved passage. On the one hand, it increases the flow path. More importantly, when the air flow passes through the horizontal flow air passage 311, the first dust removal unit 310 plays a role in blocking the air flow. The air flow hits the channel wall of the first dust removal unit 310, and the gas detours and continues to move forward, while the broken dust hitting the channel wall moves downward along the channel wall and converges towards the dust outlet of the dust removal device, thereby improving the separation effect.
[0039] In one or more specific embodiments of the present utility model, to obtain a better separation effect, the distance between two adjacent first dust removal units 310 is 2 - 5 cm, the angle B of the first peak 314 is a right angle, and the angle A of the first valley 313 is a right angle.
[0040] To obtain a better separation effect, the area of the horizontal cross-section of the lower cavity 306 gradually decreases from top to bottom.
[0041] To obtain cleaner gas, in one or more specific embodiments of the present utility model, a second dust removal structure and a baffle 317 are further installed in the dust removal area 309. The second dust removal structure is located between the first dust removal structure and the air outlet area 308. The second dust removal structure includes M second dust removal units 315, and the second dust removal units 315 are arranged in sequence from left to right. A vertical flow air passage 316 is formed between two adjacent second dust removal units 315. The baffle 317 is located below the second dust removal structure. One end of the baffle 317 is connected to the rear side plate 3022 of the upper part of the dust removal device, and the other end is connected to the front side plate 3021 of the upper part of the dust removal device. The distance between the baffle 317 and the top cover 301 of the dust removal device is greater than the height of the second dust removal unit 315. The lower end of the first second dust removal unit 315 is detachably connected to the baffle 317, the upper end of the second second dust removal unit 315 is detachably connected to the top cover 301 of the dust removal device, the lower end of the third second dust removal unit 315 is detachably connected to the baffle 317, the upper end of the fourth second dust removal unit 315 is detachably connected to the top cover 301 of the dust removal device, and so on. M is a natural number greater than two.
[0042] Those skilled in the art should understand that the detachable connection can be connected by a screw and nut detachable method, or by other detachable methods, and no special limitation is made here. Those skilled in the art can select according to needs.
[0043] When the airflow from the first dust removal structure enters the air inlet area, then enters the vertically flowing air passage 316, flows from top to bottom and then from bottom to top, the gas after the second dust removal enters the air outlet area 308, and then enters the second pipeline 4 to further realize gas-solid separation.
[0044] In one or more specific embodiments of the present invention, a number of small holes for the falling of broken dust are provided at the position of the baffle 317 facing the vertically flowing air passage 316, facilitating the separated broken dust to fall into the lower cavity 306 and converge towards the dust outlet of the dust removal device.
[0045] In one or more specific embodiments of the present invention, when M is 6, a better dust removal effect can be obtained.
[0046] In order to obtain a better separation effect, the center line of the second dust removal unit 315 is the center line 318 from front to back. The horizontal cross-section of the second dust removal unit 315 is centered on the center line 318 from front to back, and is alternately provided with a second peak 319 and a second valley 320. Through the arrangement of the second peak 319 and the second valley 320, the vertically flowing air passage 316 is a curved passage. On the one hand, it increases the flow path. More importantly, when the airflow passes through the vertically flowing air passage 316, the second dust removal unit 315 plays a role in blocking the airflow. The airflow impacts the channel wall of the second dust removal unit 315, and the gas detours and continues to move forward, while the broken dust that impacts the channel wall stays or falls onto the baffle 317, thereby improving the separation effect.
[0047] In one or more specific embodiments of the present invention, in order to obtain a better separation effect, the distance between two adjacent second dust removal units 315 is 2 - 5 cm, the angle D of the second peak 319 is a right angle, and the angle C of the second valley 320 is a right angle.
[0048] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
