[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] See also Figure 1-4 A waste gas dust removal device for refined lime production comprises a bag dust collector 1, a dust outlet 2, an air inlet 3, an air outlet 4 and a support plate 5. Two sets of dust outlets 2 are connected to the bottom of the bag dust collector 1, and the refined lime dust in the waste gas can be discharged from the bottom of the dust outlet 2. The air inlet 3 and the air outlet 4 are respectively connected to the two sides of the bag dust collector 1. The waste gas enters the bag dust collector 1 from the air inlet 3 and is then discharged through the air outlet 4. The support plate 5 is welded to the inner side of the bag dust collector 1, and the support plate 5 is located between the air inlet 3 and the air outlet 4. A cleaning mechanism is arranged inside the bag dust collector 1, and a dust discharge mechanism is arranged at the bottom of the dust outlet 2.

[0025] Specifically, the cleaning mechanism includes a support frame 211, a filter screen 212, an electric cylinder 213, a support rod 214, a fixed disk 215 and a cleaning sponge 216. The support frame 211 is installed on the top of the support plate 5 by screws, the filter screen 212 is arranged on the outside of the support frame 211, and a circular groove adapted to the support frame 211 is opened on the top of the support plate 5. One end of the support rod 214 is fixedly connected to the output end of the electric cylinder 213, and the outer surface of the support rod 214 is slidably connected to the plate body at the top of the support frame 211. The other end of the support rod 214 is welded to the middle position of the top of the fixed disk 215. The cleaning sponge 216 is installed on the bottom of the fixed disk 215 by screws. The outer surfaces of the fixed disk 215 and the cleaning sponge 216 are slidably connected to the inner side of the support frame 211 and the filter screen 212. A mounting plate 217 is welded on the inner side of the bag dust collector 1, and the electric cylinder 213 is installed on the top of the mounting plate 217.

[0026] Through the above technical scheme, after the exhaust gas enters the bag dust collector 1 from the air inlet 3, the exhaust gas enters the inner side of the filter mesh 212, and the exhaust gas passes through the filter mesh 212, and the refined lime dust in the exhaust gas is filtered to the inner side of the drive motor 112. When there is too much refined lime dust attached to the inside of the filter mesh 212, the electric cylinder 213 is started, and the electric cylinder 213 drives the fixed plate 215 to move up and down through the support rod 214. When the fixed plate 215 drives the cleaning sponge 216 to move up and down, the cleaning sponge 216 cleans the refined lime dust attached to the inner side of the filter mesh 212, so that the dust can be cleaned up in time and conveniently, so that the bag dust collector 1 can clean the exhaust gas more cleanly.

[0027] Specifically, the dust exhaust mechanism includes a pressure sensor 111, a drive motor 112, a connecting rod 113 and a baffle 114. Two groups of pressure sensors 111 are installed on both sides of the bag dust collector 1, the drive motor 112 is installed on one side of the dust outlet 2, one end of the connecting rod 113 is fixedly connected to the output end of the drive motor 112, and the other end of the connecting rod 113 is rotatably connected to the inner side of the dust outlet 2. The outer side of the baffle 114 is fixedly connected to the outer surface of the connecting rod 113 by screws, and the two groups of baffles 114 are symmetrically distributed on both sides of the bottom of the dust outlet 2.

[0028] Through the above technical solution, the pressure sensor 111 can be connected to an external display to display the data detected by the pressure sensor 111. When the refined lime dust falls to the bottom side box of the bag-type dust collector 1, the pressure generated by the refined lime dust will be detected by the pressure sensor 111, thereby determining the weight of the dust inside the bag-type dust collector 1. When the refined lime dust inside the bag-type dust collector 1 accumulates to an appropriate weight, the drive motor 112 is started, and the drive motor 112 drives the baffle 114 to rotate through the connecting rod 113. When the baffle 114 rotates downward, the refined lime dust is discharged from the dust outlet 2 in time, making the bag-type dust collector 1 more convenient to use.

[0029] When in use, by adjusting the height of the fixed plate 215, the fixed plate 215 drives the cleaning sponge 216 to move up and down, and the cleaning sponge 216 cleans the fine lime dust attached to the inner side of the filter mesh 212, so that the dust can be cleaned up in time and conveniently, so that the bag dust collector 1 can clean the exhaust gas more cleanly.
