Description
[technical field]
The utility model relates to a kind of cleaner, and particularly a kind of engineering machinery is store the empty filter of dirt formula with high efficient low resistance cyclone.
[background technology]
The effect of empty filter is the impurity in the filtered air.Engineering machinery can suck a large amount of dust in gas handling system when operation, using the empty filter of high efficient low resistance cyclone storage dirt formula can make the air that enters engineering machinery engine is clean air, is not worn with the protection engine.Can be affected the service life of the empty filter of high efficient low resistance cyclone storage dirt formula according to environment for use is different.Existing cleaner is not provided with Dust Storage Room, and it makes the bulky grain dust still filter indoor circulation after filtration when the work of filtration; through certain precipitation, can result in blockage to filter core, make the filter element life premature termination; add the frequency that the big customer changes filter core, improved cost, cause waste.
In addition; existing engineering machinery is after whole steel wire grown cutting by the height of product requirement with exhibition with the catch net of empty filter; the welding of two Cutting Edges forms; Cutting Edge out-of-flatness and sharp edge is arranged; in carrying out assembly manipulation, scratch filter core paper easily; thereby reduced the filter efficiency of product, and the operator scratches at the sharp edge of the easy protected net of operating process.Also have, existing engineering machinery is that rod-pulling type is connected with the empty filter housing and the installation form of filter core, and dismounting is convenient inadequately; The screw thread of pull bar is easy to wear, has shortened the service life of housing; Rod-pulling type is installed also needs to use seal gasket filter core to be installed to guarantee sealing, and the long-time seal gasket that uses can wear out, be out of shape, and increases trouble and the cost of client when renew cartridge more.
[utility model content]
The main technical problems to be solved in the utility model is: a kind of Dust Storage Room structure that added is provided, improved the empty filter of high efficient low resistance cyclone storage dirt formula in filter efficiency and main filter core service life, stop up the problem that service life is short easily to solve the filter core that exists in the above-mentioned prior art.
Further technical problem to be solved in the utility model is: provide a kind of filter core catch net to have folded edge, housing and housing end plug and link the empty filter of high efficient low resistance cyclone storage dirt formula that connects by plate, exist the catch net sharp edge easily to scratch filter core paper and operator, housing and housing end plug folding dress problem easily inadequately in the above-mentioned prior art to solve.
The technical scheme that solves the problems of the technologies described above is: the empty filter of a kind of high efficient low resistance cyclone storage dirt formula; comprise housing; housing end plug and the main filter core that is installed in the housing; housing is connected by detachable structure with housing end plug; described main filter core is mainly by upper end cover; bottom end cover; catch net and filter core paper constitute; described main filter core bottom end cover is with the main filter core outside and housing; space between the housing end plug is separated to form the top and is the filter chamber; the below is the structure of Dust Storage Room; have through hole on the main filter core bottom end cover, filter chamber and Dust Storage Room connect by the through hole on the main filter core bottom end cover.
Described catch net is to be formed by the silk screen two Cutting Edges welding that launches, and welding two Cutting Edges of silk screen have the folded edge that forms through pressing lap.
Be provided with the hawk of leading of the guiding dust flow direction in the described housing end plug, also be provided with at least two in the housing end plug and prevent that dust is back to the baffle plate of filter chamber, also be provided with the boss that is used for cooperating installation on the housing end plug with housing.
Described housing end plug lateral surface is provided with at least 3 plate Button Blocks, and the plate button is installed on the plate Button Block, housing end plug by the fastening of plate button on housing.
The empty filter of this high efficient low resistance cyclone storage dirt formula also is provided with safe filter core, and described safe filter core is installed in the main filter core.
Owing to adopt said structure, the empty filter of high efficient low resistance cyclone storage dirt formula of the utility model has following beneficial effect:
1, the utility model has added the Dust Storage Room structure, and after filtering dust directly enters Dust Storage Room in the filter chamber, and dust filtering indoor circulation, has not only improved filter efficiency, and protected main filter core, thereby improved the service life of main filter core.The utility model is that the bottom end cover by main filter core is separated to form Dust Storage Room with housing end plug, Dust Storage Room and filter chamber connect by the through hole on the main filter core bottom end cover, product with compact structure, and manufacturing procedure is simple, easy for installation, save time, material-saving, cost be low, reduced client's cycle of change owner filter core more, reduces client's use cost greatly.In addition, the advantage of this class Dust Storage Room is that the dust of discharging can directly not be discharged in the atmosphere, helps environmental protection.
2, the utility model catch net is formed by welding by silk screen, two Cutting Edges that the silk screen welding forms have the folded edge that forms through pressing lap, and in the operation of suit filter core paper, filter core paper is difficult for being scratched, effectively guaranteed product quality, production efficiency also is improved; Simultaneously also protect the operator in operating process, to be difficult for being scratched.
3, the structure that is connected for the plate button of the housing of the utility model and the installation form of filter core, the client does not more need to use the nut assembling during renew cartridge, more need not make things convenient for the client to install by specific purpose tool; Filter core is installed does not need to use seal gasket, makes things convenient for more renew cartridge of client, has more reduced the more cost of renew cartridge of client; Plate button mounting structure uses housing end plug to compress filter core to reach sealing effectiveness, has increased the service life of housing, reduces client's use cost.
4, safe filter core provides high security, high-quality protection; main filter core is because the improper damage of maintenance or when losing efficacy; safe filter core still keeps work; particularly under the extremely many situations of dust, extra protective effect is arranged; when change owner filter core more, can also prevent that dust from directly entering engineering machinery engine.
Below, the technical characterictic to the empty filter of the high efficient low resistance cyclone of the utility model storage dirt formula is further described in conjunction with the accompanying drawings and embodiments.
