[0026] A flue gas treatment device comprises a flue gas treatment box 1, wherein the interior of the flue gas treatment box 1 is hollow, a front end opening of the flue gas treatment box 1 is provided with a through hole 2 connected to the interior of the flue gas treatment box 1, a baffle 3 is movably provided on the through hole 2, a flue gas treatment mechanism 4 is provided inside the flue gas treatment box 1, the flue gas treatment mechanism 4 comprises a drum 5, a bag filter 6 is provided on the drum 5, drum shafts 7 are fixedly provided at both ends of the drum 5, a drum gear 8 is provided on the drum shaft 7, and a transmission belt 9 and a tooth plate 10 are provided at the upper and lower ends of the drum gear 8, respectively.

[0027] Specifically, the hollow design of the flue gas treatment box 1 provides a certain space for the flue gas to be filtered inside.

[0028] Specifically, the flue gas is treated by the flue gas treatment mechanism 4 and then discharged, which is safe and environmentally friendly.

[0029] Specifically, the flue gas treatment mechanism 4 is arranged inside the flue gas treatment box 1, preferably, in the middle, and the flue gas treatment box 1 is divided into two layers, the upper part is an unfiltered chamber, which is also provided with an air inlet 25; the lower part is a filtered chamber, which is also provided with an exhaust hole.

[0030] Specifically, the flue gas treatment mechanism 4 is controlled by a PLC controller. A circuit board connected to the controller is provided inside the flue gas treatment mechanism 4, which is not shown in the circuit board diagram. The PLC controller controls mechanical operations as an existing technology, so its control program and controller model are not described here in detail.

[0031] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown:

[0032] The transmission belt 9 and the toothed plate 10 are both provided with teeth 11 meshingly connected with the drum gear 8 .

[0033] The left and right side walls of the flue gas treatment box 1 are hollow with side wall cavities 16, and the rear wall of the flue gas treatment box 1 is hollow with a rear wall cavity 17, and the side wall cavity 16 and the rear wall cavity 17 are connected.

[0034] The side wall cavity 16 is provided with a slide groove 18 , the roller shaft 7 is slidably disposed on the slide groove 18 , and the roller gear 8 , the transmission belt 9 and the toothed plate 10 are all disposed in the side wall cavity 16 .

[0035] A fixing plate 20 is fixedly provided on the rear wall cavity 17 , and a servo motor 12 is connected to the fixing plate 20 . The output shaft of the servo motor 12 is connected to a motor gear 13 , and the motor gear 13 is meshed and transmission-connected with the upper side of the transmission belt 9 .

[0036] The rear wall cavity 17 is provided with a support rod 14, and the left and right ends of the support rod 14 are respectively connected to the transmission belts 9 on the left and right sides. The side wall cavity 16 is fixedly provided with a support shaft 19, and the other end of the support shaft 19 is rotatably connected to one end of the transmission belt 9.

[0037] Specifically, in order to realize the rolling of the drum 5, a servo motor 12 is provided to drive the motor gear 13, drive the transmission belt 9, drive the drum gear 8, and then drive the drum 5 to roll;

[0038] Among them, the height diameter of the slide groove 18 is smaller than the height of the side wall cavity 16, and the diameter of the roller gear 8 is larger than the diameter of the roller shaft 7. Therefore, when the roller gear 8 moves in the side wall cavity 16, it will not fall out of the slide groove 18, that is, it is confined in the side wall cavity 16.

[0039] Among them, the length of the side wall cavity 16 is greater than the length of the slide groove, the length of the transmission belt 9 and the tooth plate 10 are also greater than the length of the slide groove 18, and the length of the slide groove 18 is greater than the length of the inner cavity of the flue gas treatment box 1. Therefore, the stroke of the drum 5 can completely cover the inner cavity of the flue gas treatment box 1. Therefore, when the drum 5 rolls once, the bag filter 6 can completely cover the inner cavity of the flue gas treatment box 1 after being unfolded, and can filter out all the smoke coming in from the air inlet.

[0040] Among them, a roller groove is also provided on the rear wall of the inner cavity of the flue gas treatment box 1. The roller groove is arranged at the front end of the rear wall cavity 17 and is independently opened. The roller 5 rolls to the rolling groove, so the bag filter 6 can completely cover the inner cavity of the flue gas treatment box 1.

[0041] A door-blocking movable groove 24 is provided at the top of the through hole 2 , and the door-blocking movable groove 24 and the door-blocking movable groove 24 are plugged into each other.

[0042] A stud 21 is formed upward at the bottom of the through hole 2 , a locking plate 22 is provided at one end of the drum 5 , and matching screw holes 23 are provided on the locking plate 22 and the bag filter 6 .

[0043] Specifically, screw holes 23 are provided at both the front and rear ends of the bag filter 6. The screw holes 23 on the bag filter 6 are pressed with rubber rings to prevent derailment. One end of the screw hole 23 on the bag filter 6 is locked and connected to the screw hole 23 of the locking plate 22, and the other end is locked and connected to the stud 21, so that the assembly of the bag filter 6 is completed.

[0044] Specifically, the stud 21 also plays a limiting role. When the roller 5 is rolled up to the through hole 2, it is limited by the stud 21 to avoid falling out of the through hole 2 directly.

[0045] Specifically, when the through hole needs to be opened, the handle is directly lifted to insert the blocking door 3 into the blocking door movable groove 24, and then the dirty roller 5 can be taken out and a new roller 5 can be put in.

[0046] The use principle of the utility model is as follows: open the baffle 3, put the new roller 5 into the through hole 2, the new roller 5 and the bag filter 6 are rolled together, and the bag filter 6 will leak out of the edge of the screw hole 23 after being rolled up, and then be locked on the stud by screws, the roller 5 and the roller gear 8 are integrally formed, so the roller gear 8 is put into the side wall cavity 6 together, and meshes with the transmission belt, and then start the motor to rotate forward and flip, so as to control the travel of the roller 5 on the slide 18, and the smoke passes through the bag filter 6 to filter impurities, and when the filter is saturated, the bag filter is rolled up. 6, wherein the winding direction is clockwise, and the winding direction can be controlled by controlling the transmission direction of the servo motor, wherein clockwise winding can ensure that the impurities on the bag filter 6 are well wrapped and will not leak out; wherein, the row of rollers 5 and bag filter 6 can be prepared in advance, thereby improving the working efficiency; wherein, when winding, when the roller 5 rolls to the through hole 2, the roller 5 can be unloaded by a forklift or other tools, which is practical and safe; wherein, when installing the roller 5, it is only necessary to lock the bag filter and the studs to complete the installation, and the installation procedure is simple, replacing the traditional surrounding installation.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
