The recovery trough 320 uses a rectangular box body with a length not less than the length of the wire brush roller 110, and is not closed near the upper surface of the wire brush roller 110. One end of the wire brush roller 110 passes through one side of the frame 310 and is rotatably connected to the opposite side using a bearing or a round hole.

[0032] The climbing lifting mechanism 200 is clamped on the side wall of the pole plate 10, and the cleaning mechanism and the collecting mechanism 300 are extended between the pole plate 10 and the pole line 20. When the motor 222 drives the wire brush roller 110 to rotate and clean the dust and dirt on the pole plate 10 and the pole line 20, the blowing assembly 330 is turned on.

After the wire brush roller 110 is cleaned, the recovery tank 320 is removed and the dust and dirt are cleaned.

[0033] The technical solution of the climbing brush cleaning device for the electric precipitator of a coal-fired boiler adopted in this application can achieve the following beneficial effects:

[0034] By setting up a recovery trough 320, the dust and dirt on the pole plate 10 and the pole line 20 are separated and fall into the recovery trough 320 by gravity, thereby solving the problem that the dust and dirt after cleaning are difficult to collect and clean; by setting up a blowing assembly 330, a breeze is used to drive the dust and dirt floating in the air driven by the wire brush roller 110 to fall into the recovery trough 320 following the direction of the wind, thereby further cleaning the dust and dirt, and solving the problem that the dust and dirt continue to adhere to the surface of the pole plate 10 and the pole line 20 after falling, resulting in a decrease in the dust removal efficiency of the coal-fired boiler electrostatic precipitator; at the same time, the frame 310 supports one end of the wire brush roller 110 away from the box body 210, thereby solving the problem that the wire brush roller 110 is relatively long and is prone to swinging when rotating, thereby damaging the pole plate 10 and the pole line 20.

[0035] Furthermore, a first guide groove and a second guide groove are installed in the box body 210 at positions corresponding to the tensioning wheel 232 and the third sprocket wheel 241. The first guide groove is arranged at the bottom of the box body 210 corresponding to the tensioning wheel 232, and the second guide groove is arranged at the top of the box body 210 corresponding to the third sprocket wheel 241. The tensioning wheel 232, the first guide groove, the third sprocket wheel 241 and the second guide groove form an S-shaped channel, and one end of the lifting chain 250 passes through the S-shaped channel and is connected to one end of the pole plate 10 away from the box body 210, thereby realizing the positioning of the lifting chain 250.

[0036] In the above scheme, in order to achieve the purpose of stable lifting, the box body 210 is equipped with a first clamping wheel 261 and a second clamping wheel 262. The first clamping wheel 261 and the second clamping wheel 262 are respectively arranged on the side of the box body 210 close to the pole plate 10, and the distance between the first clamping wheel 261 and the second clamping wheel 262 is not greater than the thickness of the pole plate 10. By arranging the first clamping wheel 261 and the second clamping wheel 262, the entire device is positioned on the frame of the pole plate 10 to ensure that the wire brush roller 110 is close to the pole plate 10 and the pole line 20, thereby achieving the purpose of stable up and down operation.

[0037] Based on the above scheme, the frame 310 includes a bottom plate, a top plate 312, a connecting plate 313 and a supporting plate 314. The bottom plate is arranged parallel to the bottom of the wire brush roller 110. One side of the connecting plate 313 is connected to the side wall of the box body 210, and the two ends are respectively connected to the bottom plate and the top plate 312 arranged opposite to the bottom plate. The two ends of the supporting plate 314 arranged opposite to the connecting plate 313 are respectively connected to the bottom plate and one end of the top plate 312. One end of the wire brush roller 110 passes through the connecting plate 313 and is rotatably connected to the support plate 314.

[0038] Specifically, the entire frame 310 is made of an insulating board, the recovery trough 320 is arranged on the bottom plate by a detachable connection method such as bolts and slides, the blowing assembly 330 is arranged on the top plate 312, and the lengths of the bottom plate and the top plate 312 are not less than the length of the wire brush roller 110, a through hole is arranged on the connecting plate 313, the wire brush roller 110 passes through the through hole and is connected to the oppositely arranged support plate 314 using a bearing, and the connecting plate 313 is connected to the box body 210; the top plate 312 is arranged parallel to the bottom plate above and below the wire brush roller 110, the connecting plate 313 and the support plate 314 are vertically connected to the wire brush roller 110, the top plate 312 and the bottom plate, and the problem of the left and right swinging caused by the excessive length of the wire brush roller 110 is solved by arranging the connecting plate 313 and the support plate 314. At the same time, the recovery trough 320 and the blowing assembly 330 are fixed by the bottom plate and the top plate 312 parallel to the wire brush roller 110, so that the device is more stable.

[0039] Furthermore, the diameter of the wire brush roller 110 is not less than the width of the recovery groove 320. The diameter of the wire brush roller 110 is greater than the width of the recovery groove 320. When the wire brush roller 110 rotates, it extends out of both sides of the recovery groove 320 to clean the electrode plate 10 and the electrode line 20, solving the problem that the recovery groove 320 is too large and difficult to extend between the electrode plate 10 and the electrode line 20, and at the same time solving the problem that the wire brush roller 110 has a small diameter and cannot effectively clean the electrode plate 10 and the electrode line 20.

[0040] In a preferred solution, a storage box 321 is provided at the bottom of the recovery tank 320 , and the storage box 321 can slide along the bottom of the recovery tank 320 and slide out of the recovery tank 320 .

[0041] Specifically, an opening is provided on one side of the recovery tank 320, the size of the bottom of the storage box 321 is the same as the size of the bottom of the recovery tank 320, and the cross-sectional size of the storage box 321 is the same as the size of the opening, one end of the storage box 321 extends into the recovery tank 320 through the opening, and the other end of the storage box 321 is fixed to the side wall of the recovery tank 320 with the opening by a detachable connection method such as but not limited to bolts, buckles, spring clips, etc.; when the pole plate 10 and the pole line 20 are cleaned, the storage box 321 is pulled out from the opening side of the recovery tank 320, and the storage box 321 is cleaned. After cleaning, the storage box 321 is detachably placed in the recovery tank 320, or a new storage box 321 is directly replaced and placed in the recovery tank 320, so as to solve the problem that the collection space of the recovery tank 320 is small, the device needs to be started and stopped multiple times, and multiple installations and disassemblies are required, resulting in low work efficiency.

[0042] Based on the above scheme, the two opposite side walls of the recovery tank 320 are arranged in an inverted eight shape, and the bottom of the recovery tank 320 is an arc structure. Specifically, the inner wall of the recovery tank 320 is provided with an inverted eight-shaped mechanism, and its bottom is arranged with an arc structure, and the corresponding bottom of the storage box 321 is also arranged with an arc structure. When the dust and dirt fall on the inner wall of the recovery tank 320, the dust and dirt are drawn into the bottom of the storage box 321 along the slope. By setting the inverted eight-shaped mechanism and the arc structure, the setting of the edges and corners is reduced, the area of ​​the cleaning dead corner is reduced, and the cleaning difficulty is reduced, thereby improving the cleaning efficiency.

[0043] In a preferred embodiment, the blowing assembly 330 includes a fan 331 and an air duct 332, the fan 331 is arranged on the box body 210, the air outlet 333 of the fan 331 is connected to the air inlet of the air duct 332, the air duct 332 extends into the top plate 312, and a plurality of air outlet holes 333 are arranged on the air duct 332, and the air outlet holes 333 extend out of the top plate 312 close to the side of the wire brush roller 110.

[0044] Specifically, the fan 331 is arranged on one side of the box body 210, the air duct 332 uses a sealed tube, a blind hole is arranged on the top plate 312, and a plurality of through holes are arranged in the blind hole. The through holes are equidistantly penetrate the side of the top plate 312 close to the wire brush roller 110 and are connected to the blind hole. The air duct 332 extends into the blind hole, and a plurality of air outlet holes 333 are equidistantly arranged on the air duct 332, and the number of the air outlet holes 333 corresponds to and coincides with the number of the through holes. The fan 331 blows the wind out from the air outlet holes 333 through the air duct 332, so that the dust and dirt fall in the direction of the wind flow, and the operation is simpler and more convenient, which solves the problem that the dust and dirt continue to adhere to the surface of the electrode plate 10 and the electrode line 20, resulting in a decrease in the dust removal efficiency of the electric precipitator of the coal-fired boiler.

[0045] Furthermore, at least two air ducts 332 are provided and symmetrically arranged on one side of the top plate 312 close to the wire brush roller 110. Four blind holes are provided on the top plate 312 and symmetrically arranged on both sides of the central axis of the top plate 312 (the central axis of the top plate 312 is the center line parallel to the wire brush roller 110), and a gas diverter is provided at the air outlet of the fan 331. Four air ducts 332 are provided on the gas diverter, and the four air ducts 332 extend into a blind hole respectively, and the air outlet hole 333 is overlapped with the through hole. By symmetrically arranging on the top plate 312, the wind blows downward from both sides to avoid being blocked by the wire brush roller 110 and thus changing the flow direction, thereby solving the problem of secondary attachment of dust and scale to the pole plate 10 and the pole line 20 due to the change in the flow direction of the wind.

[0046] The above-described embodiments only express the way of equipment layout of the present application, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application; it should be pointed out that for ordinary technicians in this field, several adjustments and improvements can be made without departing from the concept of the present application, which all belong to the scope of protection of the present application; therefore, the scope of protection of the patent of this application shall be based on the attached claims.
