In view of the above problems, the utility model provides a kind of smoke filtration dust-extraction unit, can effectively to flue dust into Row filtering, the flue dust being filled into can also be carried out to recycling prevents secondary pollution, the specific scheme is that including the shell of a cuboid Body, the bottom of shell are equipped with cinder box, and the lower part side of shell is equipped with blast pipe, and the top of shell is equipped with discharge pipe, the shell Internal portion has the chamber of flow of flue gas, and the inside of shell is additionally provided with blower, and blower is located at the top of blast pipe, while entering the wind Primary filter is additionally provided between pipe and blower；Flue gas enters chamber in blast pipe, forms eddy flow under blower rotation and transports upwards It is dynamic, it is discharged from discharge pipe, will then be dropped into the cinder box of bottom by the dust of by-pass filtration net filtration.

Further, it is additionally provided with secondary filter on the primary filter top, the mesh of secondary filter wants small It in primary filter, and is in arc surface convex design among secondary filter.

Further, it is equipped with a cleaning agency in shell right side lower part, the cleaning agency includes one horizontal Flexible hydraulic cylinder, the head end of hydraulic cylinder be can horizontal side-to-side movement telescopic rod, the head end of telescopic rod passes through shell to the left Body is placed in enclosure interior and is located at the lower part of primary filter；The head end of telescopic rod connects a floating rule, and described is hanging rod upper surface It is provided with hairbrush, the top of hairbrush is contacted with primary filter, and the size of floating rule is mutually matched with primary filter.

Further, the cinder box is tool there are four the funnel-form for tilting smooth side, and top large port is fixed on shell The bottom of body, lower port disposition is in a sink, convenient for collecting dust by water.

Further, the cinder box is the cone cell with bottom surface and four inclined surface, and bottom surface is equipped with an opening, opens It is hinged at mouthful to be equipped with the lid that beaten or close, while a lateral strut is equipped in cinder box bottom sidewall, strut top is fixed One curved cover plate fixes a sensor under cover board, which connect with a controller, and controller is connect with an alarm.

The advantage of the utility model is: structure is simple, can be filtered well to the flue dust of discharge, and can will filter Flue dust afterwards collects well prevents secondary pollution, and increased cleaning agency can effectively improve the filter efficiency of filter screen, Prevent blocking caused by filtering for a long time.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of an embodiment of utility model；

The overlooking structure diagram of the cleaning agency of one embodiment of Fig. 2 the utility model；

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

With reference to Fig. 1-2, the utility model provides a kind of smoke filtration dust-extraction unit, the shell 1 including a cuboid, shell The bottom of body is equipped with cinder box 2, and the lower part side of shell 1 is equipped with blast pipe 3, and the top of shell 1 is equipped with discharge pipe 4, the shell There is the chamber of flow of flue gas, the inside of shell 1 is additionally provided with blower 5, and blower 5 is located at the top of blast pipe 3, simultaneously inside body 1 Primary filter 6 is additionally provided between blast pipe 2 and blower 5；Flue gas enters chamber in blast pipe 3, is formed under the rotation of blower 5 Eddy flow moves upwards, and is discharged from discharge pipe 4, will then drop into the cinder box 2 of bottom by the dust that primary filter 6 filters.

As the improvement of scheme, it is additionally provided with secondary filter 7 on 6 top of primary filter, secondary filter 7 Mesh is less than primary filter 6, and is in arc surface convex design among secondary filter 7.

As the improvement of scheme, it is equipped with a cleaning agency 8 in the 1 right side lower part of shell, the cleaning agency 8 wraps The hydraulic cylinder 81 of a horizontal extension is included, which connects to power supply, and the head end of hydraulic cylinder 81 is provided with can be horizontal The telescopic rod 82 of side-to-side movement, the head end of telescopic rod 82 pass through shell 1 to the left and are placed in 1 inside of shell and are located at primary filter 6 Lower part；The head end of telescopic rod 82 connects a floating rule 83, and described is that 83 upper surface of floating rule is provided with hairbrush, the top of hairbrush and one Grade filter screen 6 contacts, and the size of floating rule 83 is mutually matched with primary filter 6.When energization needs to clean, hairbrush will Dust in primary filter 6 clears away point.When hydraulic cylinder 81 is idle, hairbrush walking to reset condition.This can To preset the travel time of telescopic rod 81 in controller by the way that hydraulic cylinder 81 and a controller to be attached, with Hairbrush is returned to home position after guaranteeing a cleaning period.Here home position is exactly that hanging rod is disposed adjacent to hydraulic cylinder 81 sides.Cleaning agency 8 well cleans primary filter 6, it is therefore prevented that the online mesh blocking of by-pass filtration, because one The filtration amount of grade filter screen 6 is big, so this cleaning agency 8 is positioned only at primary filter 6.

As the improvement of scheme, cinder box 2 is tool there are four the funnel-form for tilting smooth side, and top large port is fixed on shell The bottom of body 1, lower port disposition is in progress dust collection in a sink.

As the improvement of scheme, cinder box 2 is the cone cell with bottom surface and four inclined surface, and bottom surface is equipped with an opening, Opening is equipped with lid, while a lateral strut 9 is equipped in 2 bottom sidewall of cinder box, and a curved cover plate 10 is fixed on strut top, A sensor 11 is fixed under cover board 10, which connect with a controller, and controller is connect with an alarm.When cinder box 2 When the dust deposit of bottom is to certain altitude, the then signal an alert of sensor 11, openable lid is by bottom at this time Dust is let out into a returnable.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
