DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] To solve the technical problem of how the device can remove dust and exhaust gas, please refer to Figure 1-Figure 2 , this embodiment provides the following technical solutions:

[0023] An environmentally friendly dust removal device for construction engineering includes a box body 1 and a cleaning mechanism 2. A cloth bag 16 is fixedly installed in the box body 1 through a partition 17. An exhaust hole 171 is opened in the partition 17. An ash outlet 11 is opened at the bottom of the box body 1. An air inlet 12 is provided at one end of the box body 1, and the other end is sealedly connected to an air pump 14 through an exhaust pipe 13. The other end of the air pump 14 is sealedly connected to an air outlet 15.

[0024] Specifically, the air pump 14 is started, so that a large amount of dust and exhaust gas generated at the construction site is sucked into the box body 1 from the air inlet 12, and the gas flows upward through the bag 16. Dust with large particles and high specific gravity settles down due to gravity and is discharged from the ash outlet 11. When the gas containing finer dust passes through the bag 16, the dust is retained, so that the gas is purified and passes through the exhaust hole 171 and the exhaust pipe 13, and is finally discharged from the outlet 15.

[0025] To solve the technical problem of how the device cleans the outer wall of the bag, please refer to Figure 3-Figure 4 , this embodiment provides the following technical solutions:

[0026] The cleaning mechanism 2 includes an outer cleaning component 21 and an inner cleaning component 22. The outer cleaning component 21 includes a sleeve 211 rotatably arranged outside the cloth bag 16. There are two sleeves 211 and they are symmetrically arranged up and down. A cleaning plate 23 is symmetrically connected between the two sleeves 211. A gear ring 212 is fixedly connected to the outer wall of the sleeve 211 at the upper end.

[0027] The cleaning mechanism 2 further comprises a motor 24 , which is fixedly mounted on the top of the housing 1 . The output end of the motor 24 is connected to a driving shaft 25 , to which a second gear 26 is fixedly connected. The second gear 26 is meshedly connected to the ring gear 212 .

[0028] Specifically, the motor 24 is started, and the motor 24 drives the second gear 26 to rotate through the drive shaft 25. The second gear 26 then drives the ring gear 212 meshing therewith to rotate. The ring gear 212 drives the sleeve 211 fixedly connected thereto to rotate. The sleeve 211 drives the cleaning plate 23 fixedly connected thereto to rotate and wipes the outer wall of the cloth bag 16.

[0029] To solve the technical problem of how the device cleans the inner wall of the bag, please refer to Figure 3-Figure 4 , this embodiment provides the following technical solutions:

[0030] The inner cleaning assembly 22 includes a rotating rod 221 rotatably disposed in the cloth bag 16, the lower end of the rotating rod 221 is symmetrically connected to the cleaning plate 23, the upper end of the rotating rod 221 is connected to the first gear 223 through the rotating shaft 222, and the first gear 223 is movably connected to the inner wall of the box body 1.

[0031] The driving shaft 25 is fixedly connected with a third gear 27 , and the third gear 27 is meshedly connected with the first gear 223 .

[0032] Specifically, the motor 24 is started, and the motor 24 drives the third gear 27 to rotate through the driving shaft 25. The third gear 27 then drives the first gear 223 meshing therewith to rotate. The first gear 223 drives the rotating rod 221 to rotate through the rotating shaft 222. The rotating rod 221 drives the cleaning plate 23 fixedly connected thereto to rotate and wipe the inner wall of the cloth bag 16.

[0033] To solve the technical problem of how to achieve cleaning on the cleaning plate, please refer to Figure 5 , this embodiment provides the following technical solutions:

[0034] The cleaning plate 23 includes a fixing plate 231 , a side end of the fixing plate 231 is slidably connected with a brush 232 , the brush 232 is closely connected to the inner and outer walls of the cloth bag 16 , and a spring 233 is connected between the brush 232 and the fixing plate 231 .

[0035] Specifically, through the design of the spring 233, the brush surface of the brush 232 is always in close contact with the inner and outer walls of the cloth bag 16. At this time, the brush 232 can be inserted into the filter hole and capture tiny particles such as dust. When the cleaning plate 23 rotates, the brush 232 can remove dust from the filter hole through physical friction.

[0036] Working principle: When the bag 16 needs to be cleaned, the motor 24 is started. The motor 24 drives the second gear 26 and the third gear 27 to rotate through the drive shaft 25. The second gear 26 drives the gear ring 212 meshing therewith to rotate. The gear ring 212 drives the sleeve 211 fixedly connected thereto to rotate. The sleeve 211 drives the cleaning plate 23 fixedly connected thereto to rotate along the outer wall of the bag 16 to achieve wiping cleaning. The third gear 27 drives the first gear 223 meshing therewith to rotate. The first gear 223 drives the rotating rod 221 to rotate through the rotating shaft 222. The rotating rod 221 drives the cleaning plate 23 fixedly connected thereto to rotate along the inner wall of the bag 16 to achieve wiping cleaning.
