DETAILED DESCRIPTION

[0025] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] See also Figure 1 to Figure 7As shown, a micro-mist dust removal device for a bucket elevator discharge port of an aluminum electrolysis 500KA series includes a frame 1, a bracket 5, a micro-mist 6 and a bucket elevator casing 7. The frame 1 includes a nozzle 2, a sensor 3 and an air suction groove 4. The frame 1 is a rectangular parallelepiped structure with an opening in the center, and its opening is aligned with the discharge port of the bucket elevator casing 7. The bracket 5 is rotatably connected to both sides of the frame 1, the micro-mist 6 is installed on the top of the bucket elevator casing 7 and connected to the frame 1, the nozzle 2 is installed on both sides of the frame 1 and on its upper surface, the sensor 3 is arranged on the bracket 5 and aligned with the discharge port, and the air suction groove 4 is arranged on the frame 1 and parallel to the opening direction of the frame 1.

[0027] The device extends the material discharge path of the material discharge port of the bucket elevator housing 7 through the frame 1, reduces the stacking impact force between materials under the loss of friction, reduces the degree of dust, and at the same time sprays the micro mist generated by the micro mister 6 through the nozzle 2. The micro mist combines with the solid particles floating in the air and increases their gravity, so that the solid particles fall quickly to further reduce dust. The bracket 5 is used to adjust the inclination of the frame 1 to make it suitable for various types of bucket elevator housings 7. The air suction groove 4 is used to absorb the solid particles around the frame 1 that are not affected by the nozzle 2 and return them to the inside of the frame 1. The sensor 3 is a photoelectric sensor and feeds back to the micro mister 6 to control the nozzle 2.

[0028] See also Figure 1 to Figure 4 As shown, the nozzle 2 includes a connecting frame 21, an inclined hole 22 and a movable joint 23. The inclined holes 22 are arranged on both sides of the frame 1 and on its upper surface. The nozzle 2 is inserted into the frame 1 along the inclined holes 22. The connecting frame 21 connects the tails of all the nozzles 2 and connects to the micro mister 6. The movable joint 23 is installed on the top of the nozzle 2.

[0029] The connecting frame 21 is used to unify all the nozzles 2 to facilitate the concentrated feeding and mist production of the micro-mist 6. The inclined hole 22 allows the nozzle 2 to have a certain angle in the opening of the frame 1 to avoid damage to the nozzle 2 by material impact when pouring the material. The movable joint 23 can be quickly installed and disassembled from the top of the nozzle 2 for easy maintenance.

[0030] See also Figure 1 to Figure 3 As shown, the connecting frame 21 includes a boss 211, a connecting pipe 212 and a fixing rod 213. The boss 211 is arranged at both ends of the connecting frame 21. One end of the connecting pipe 212 is installed on the boss 211, and the other end is connected to the side of the micro mister 6. The fixing rod 213 is arranged on the connecting frame 21 and fixes the tail of the nozzle 2.

[0031] The boss 211 is used to install the connecting pipe 212, which is used to transfer the micro mist generated by the micro mister 6 and press the micro mist into the nozzle 2 from the tail of the nozzle 2 through the fixing rod 213. At the same time, the connecting frame 21 further strengthens the firmness between the nozzle 2 and the frame 1 to prevent the nozzle 2 from falling off from the frame 1.

[0032] See also Figure 4 As shown, the movable joint 23 includes a needle tube 231, a needle cap 232 and a needle hole 233. The needle tube 231 has four divergently arranged on the movable joint 23, the needle cap 232 is installed on the top of the needle tube 231, and the needle hole 233 is arranged in the center of the needle cap 232.

[0033] The four divergent needle tubes 231 increase the spray area of ​​the movable joint 23 and improve the dust reduction efficiency. The needle cap 232 is installed on the needle tube 231 through a thread. The spray rate of the nozzle 2 can be changed by adjusting the diameter of the needle hole 233 on the needle cap 232.

[0034] See also Figure 2 to Figure 5 As shown, the air intake slot 4 includes a fan 41, a filter 42 and an air vent 43. The fan 41 is installed in the air intake slot and inhales air from the outside to the inside. The filter 42 is installed on the inner wall of the opening of the frame 1, and the air vent 43 is installed at the notch of the air intake slot.

[0035] The air suction groove 4 is at a distance from the outlet of the frame 1 to avoid inhaling the poured material. When the fan 41 absorbs the dust, it first passes through the air vent 43 and then is discharged to the inside of the frame 1 through the filter 42. The filter 42 is used to prevent the material poured out from the opening of the frame 1 from being discharged back from the air suction groove 4 to the frame 1. The air vent 43 changes the ability of the air suction groove 4 to absorb dust by adjusting the transparent area at the notch of the air suction groove 4.

[0036] See also Figure 2 to Figure 7 As shown, the filter screen 42 includes a frame 421 , a rotating shaft 422 and a rotating hole 423 . The frame 421 surrounds the filter screen 42 , the rotating shaft 422 is mounted on the frame 421 , and the rotating hole 423 is arranged on the air suction groove 4 .

[0037] The frame 421 is installed in the rotating hole 423 through the rotating shaft 422 and rotates around the rotating shaft 422 with the filter 42. The filter 42 rotates to form a certain angle in the opening of the frame 1 to avoid excessive air pressure in the suction groove 4 caused by clogging of the filter 42 after the device has been working for a long time, thereby affecting the efficiency of absorbing dust.

[0038] See also Figure 2 to Figure 6 As shown, the ventilation window 43 includes window blades 431 , connecting rods 432 and lifting frames 433 . The window blades 431 are arranged in an array in the ventilation window 43 . The connecting rods 432 are installed on the window blades 431 . The lifting frames 433 vertically connect all the connecting rods 432 .

[0039] The lifting frame 433 controls all the window blades 431 synchronously through the aggregate connecting rod 432. Pulling up the lifting frame 433 can increase the air circulation area of ​​the ventilation slot opening and enhance the ability of the suction slot 4 to absorb dust. Lowering the lifting frame 433 reduces the air circulation area of ​​the ventilation slot opening and prevents materials from piling up too high and being sucked into the suction slot 4.

[0040] See also Figure 1 and Figure 2 As shown, the bracket 5 includes a rotating shaft 51, a knob 52 and a connecting line 53. The rotating shaft 51 passes through the side of the frame 1 and is rotatably connected to the two ends of the bracket 5. The knob 52 is installed at both ends of the rotating shaft 51. One end of the connecting line 53 is connected to the side of the micro-mist 6, and the other end is connected to the sensor 3.

[0041] Since the pouring openings of various bucket elevator casings 7 have different inclination angles, the inclination angle of the frame 1 is adjusted by the bracket 5 and the rotating shaft 51 to adapt to the pouring openings of various bucket elevator casings 7, and the knob 52 is used to facilitate the rotation of the frame 1.

[0042] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
