Abstract
The utility model discloses a pre-filtering device for a sweeping machine. The pre-filtering device comprises an air inlet connected with a box filtering screen and an air outlet connected with a fan, as well as a filter drum with an inner cavity and a garbage settler connected with the filter drum, wherein the inner wall of the filter drum is provided with an eddy inlet and an eddy outlet which are used for communicating the inner cavity of the filter drum and the garbage settler, the air inlet is arranged on the outer wall of the filter drum along the tangential direction of the filter drum and is communicated with the inner cavity of the filer drum, and the at least one end of the filter drum is provided with the air outlet communicated with the inner cavity of the filter drum. Since a pre-filtering system is arranged between the garbage settler and the fan, the dust content of air flow entering the fan is reduced and the wear speed of the impeller of the fan is slowed down greatly; air flow containing impurities is prefiltered based on the air eddy principle, so that the dust content of air flow of a dust removing box is reduced and the dust removing efficiency and the clearness of discharged air are improved.
Description
Technical field
The utility model relates to automotive field, and specifically a kind of sweeping machine is used pre-filtrating equipment.
Background technology
Sweeping machine utilizes negative pressure dust suction principle to carry out work, is on the basis of two types of truck chassises, installs the formed road-cleaning of required special equipment, dust suction, dust pelletizing system additional.The energy source of at present common sweeping machine dust is in the motor that independently installs additional, and the work of dust and the work of chassis portion are not disturbed mutually.Main last installing comprises the subframe of brush, suction port, conduit, casing, dust removal by filtration equipment, blower fan, motor, support motor and blower fan etc. fully for twin-engined sweeping machines.
During sweeping machine work; Left and right sides brush is swept rubbish to mid-suction inlet position and is aspirated operation; Because the external and internal pressure of suction port is poor, air enters in the suction port from back blow port and outside, air-flow and counter-blowing wind-pressure power pair from acting on time; Solid particle and AIR MIXTURES get into the rubbish flow tank from suction port along conduit.Air-flow gets into behind the flow tank because sectional area strengthens suddenly; Air velocity reduces; The particle that particle diameter is bigger is able to settle down, and meeting of particle diameter smaller particles and air-flow continue to move to the pipeline direction of blower fan together, and air-flow gets into dust pelletizing system through blower fan and enters atmosphere.Since have the distinguished and admirable of small solid particle through blower fan, serious to the damage in impeller of blower fan, had a strong impact on the application life of blower fan and the pressure of the follow-up dust pelletizing system of increasing,
Summary of the invention
Deficiency to the prior art existence; The utility model technical problem to be solved is; Provide a kind of and effectively carry out pre-filtering, reduce the percentage of impurity of the wind that gets into blower fan greatly, increase blower fan application life getting into containing of blower fan assorted air-flow; And alleviate the pressure of follow-up dust pelletizing system, improved the sweeping machine of dust removing effects and used pre-filtrating equipment
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of sweeping machine is used pre-filtrating equipment; The air intake and the air outlet that is connected blower fan that comprise the connect box filter screen; Also comprise filter cylinder with inner chamber and the rubbish settling tank that links to each other with filter cylinder; Offer the eddy current inlet and eddy current outlet that the filter cylinder inner chamber is connected with said rubbish settling tank at the filter cylinder inwall, said air intake is located at cartridge exine and is communicated with the filter cylinder inner chamber along the filter cylinder tangential direction, at the air outlet of filter cylinder at least one end setting and filter cylinder intracavity inter-connection.
Above-mentioned sweeping machine is used pre-filtrating equipment, and the eddy current inlet is axial arranged and corresponding with air intake along said filter cylinder, and the eddy current outlet is symmetrical set along the filter cylinder longitudinal section with the eddy current inlet.
Above-mentioned sweeping machine is used pre-filtrating equipment, and said rubbish settling tank is located at the bottom of filter cylinder, and its side is provided with chamber door.
A kind of sweeping machine of the utility model with the advantage of pre-filtrating equipment is: through between dustbin and blower fan, increasing pre-filtration system, the air-flow dustiness that gets into blower fan is reduced, greatly reduce the rate of wear of draught fan impeller; Utilize air-flow whirlpool principle to carry out pre-filtering, reduced dust cleaning case air-flow dustiness, improved efficiency of dust collection and air draft cleannes containing assorted air-flow.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details;
Like Fig. 1,2, shown in 3; A kind of sweeping machine is used pre-filtrating equipment; The air intake 1 and the air outlet that is connected blower fan 2 that comprise the connect box filter screen; Also comprise filter cylinder 4 with inner chamber 3 and the rubbish settling tank 5 that links to each other with filter cylinder 4, rubbish settling tank 5 is located at the bottom of filter cylinder 4, in the side of rubbish settling tank 5 chamber door 6 is set.Offer the eddy current inlet 7 and eddy current outlet 8 that the inner chamber 3 with filter cylinder 4 is connected with rubbish settling tank 5 at the inwall of filter cylinder 4; Eddy current inlet 7 is along the axial arranged of filter cylinder 4 and corresponding with air intake 1, and eddy current outlet 8 and eddy current inlet 7 are symmetrical set along filter cylinder 4 longitudinal sections.Air intake 1 is located at the outer wall of filter cylinder 4 and is communicated with the inner chamber 3 of filter cylinder 4 along filter cylinder 4 tangential directions, at least one end of filter cylinder 4 air outlet 2 that is connected with the inner chamber 3 of filter cylinder 4 is set.
This device adopts horizontal type of attachment, utilizes air-flow whirlpool separation principle, and the large granular materials that gets into casing is separated; Air-flow is got into by filter cylinder 4 cross section tangentials, and after separating, the gas of purification gets into blower fan, and the solid particle dust of collection falls into ash bin.This device air intake 1 links to each other with the casing filter screen, and air outlet 2 links to each other with air inlet, and resistance is little; Separative efficiency is high, during work, contains assorted air-flow and gets into air intake 1 through screen pack; High velocity air forms vortex in filter cylinder 4, be provided with eddy current inlet 7 and eddy current outlet 8 in the filter cylinder 4, and most of gas is at filter cylinder 4 inside vortex; The part air communication is crossed eddy current inlet 7 and is got into rubbish settling tank 5, utilizes the pressure reduction principle to realize eddy current, makes the bigger particle separation of diameter come out to get into rubbish settling tank 5; The air-flow that has separated gets into blower fan by air outlet 2; The dust of rubbish settling tank 5 is realized toppling over of dust through the switch of chamber door 6 when dumping rubbish.
Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the utility model, the variation of making, remodeling, interpolation or replacement all should belong to the protection domain of the utility model.
