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 outlet of the dust removal device 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 is communicated with the air outlet area 308, the first pipe 2 is communicated 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, and a dust removal structure is installed in the dust removal area 309. The dust removal structure includes N dust removal units 310. The dust removal units 310 are arranged in sequence from front to back. A horizontally flowing air flow channel 311 is formed between two adjacent dust removal units 310. The top of each dust removal unit 310 is detachably connected to the dust removal device top cover 301. 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 dust removal unit 310 is detachably connected to the rear side plate 3022 of the upper part of the dust removal device. N is a natural number greater than two.

[0032] Those skilled in the art should understand that the detachable connection can be achieved by means of screw and nut detachable connection or other detachable methods. No special limitation is made here. As long as the 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 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 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 choose a specific detachable method.

[0033] When the airflow with broken dust coming from the dust suction hood 1 enters the air inlet area, then enters the horizontally flowing air flow channel 311, under the action of gravity, the broken dust falls into the lower cavity 306, 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.

[0034] In one or more specific embodiments of the present utility model, when N is 6, a better dust removal effect can be obtained.

[0035] To obtain a better separation effect, the center line of the dust removal unit 310 is the center line 312 from left to right. The horizontal cross-section of the dust removal unit 310 is alternately provided with peaks 314 and valleys 313 centered on the center line 312 from left to right. Through the arrangement of the peaks 314 and valleys 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 dust removal unit 310 plays a role in blocking the air flow. The air flow hits the channel wall of the 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.

[0036] In one or more specific embodiments of the present utility model, to obtain a better separation effect, the distance between two adjacent dust removal units 310 is 2 - 5 cm, the angle B of the peak 314 is a right angle, and the angle A of the valley 313 is a right angle.

[0037] To obtain a better separation effect, the area of the horizontal cross-section of the lower cavity 306 gradually decreases from top to bottom.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, and are not intended to limit them; although the present utility model 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 described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present utility model.
