Abstract
The utility model relates to a filter core, in particular to a high negative pressure air filter core. The filter core is provided with an upper end cover, a lower end cover, folded and wound filter paper and an inner protective net, wherein the inner protective net is pressed against the inner side of the filter paper; the upper ends and the lower ends of the filter paper and the inner protective net are fixed in the annular upper end cover and the lower end cover respectively; at least one reinforcing rib is arranged in the axial direction of the outer circular surface of the inner protective net; at least one reinforcing rib is also arranged in the axial direction on the outer side of the filter paper; and the upper ends and the lower ends of the inner protective net and an outer protective net are fixed in the annular upper end cover and lower end cover respectively. In the high negative pressure air filter core, the strength of the filter core protective net is improved by arranging the reinforcing rib in the axial direction of the outer circular surface of the inner protective net, so that the high negative pressure air filter core can bear larger air suction capacity, does not deform easily and also meets the filtering requirement of an assembly line.
Description
Technical field
The utility model relates to a kind of filter core, specifically a kind of high negative pressure Air Filter Filter Core.
Background technology
Existing high negative pressure Air Filter Filter Core still can satisfy the requirement of filtration under the less situation of air draught power, and economical and practical.But when reality was used, a cleaner will carry out the filtration of sheet material powder to two platen material cutting machines sometimes, so just requires cleaner that bigger air draught power is arranged, and just can reach well the dust-absorbing filtering effect.But because the increasing of air draught power, the inside and outside of filter core will produce very big pressure differential, and filter core is a papery, and the intensity of protecting wire net is relatively poor again, and its bearing capacity is limited, so will cause filter core to produce distortion, damage, can not satisfy the filtration requirement on the production line.
The utility model content
The technical problems to be solved in the utility model is: solve existing high negative pressure Air Filter Filter Core is easy to generate distortion, damages under bigger air draught power technical problem.The utility model provides a kind of high negative pressure Air Filter Filter Core, by reinforcement axially being set at the periphery of interior protecting wire net, improve the filter core integral intensity, thereby make the high negative pressure Air Filter Filter Core can bear bigger air draught power, filter core is difficult for producing distortion, also satisfies the filtration requirement of production line.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of high negative pressure Air Filter Filter Core, have upper end cover, bottom end cover, through the folding filter paper that rolls, near the interior protecting wire net of filter paper inboard, the two ends up and down of filter paper and interior protecting wire net all are separately fixed in the upper end cover and bottom end cover of ring-type, the periphery of interior protecting wire net axially be provided with an interior reinforcement at least, interior reinforcement is separately fixed in the upper end cover and bottom end cover of ring-type at two ends up and down.
For the intensity of to a greater extent enhancing high negative pressure Air Filter Filter Core, improve the anti-pressure ability of filter core, the filter paper outside an outer reinforcement axially is set at least, two ends are separately fixed in the upper end cover and bottom end cover of ring-type about the outer reinforcement.
The beneficial effects of the utility model are: this high negative pressure Air Filter Filter Core is under the bigger situation of air draught power, and the intensity of its filter core also can meet the demands, and is difficult for producing distortion, the filtration of the higher production line that can meet the requirements.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the specific embodiment structural representation of high negative pressure Air Filter Filter Core of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure: 1, upper end cover 2, bottom end cover 3, filter paper 4, outer reinforcement
5, interior protecting wire net 6, interior reinforcement
Has embodiment
The specific embodiment of the high negative pressure Air Filter Filter Core of the present utility model shown in Fig. 1～2, have upper end cover 1, bottom end cover 2, through the folding filter paper 3 that rolls, near the interior protecting wire net 5 of filter paper 3 inboards, the two ends up and down of filter paper 3 and interior protecting wire net 5 all are separately fixed in the upper end cover 1 and bottom end cover 2 of ring-type, the periphery of interior protecting wire net 5 axially be provided with an interior reinforcement 6 at least, filter paper 3 outsides an outer reinforcement 4 axially is set at least, interior reinforcement 6 and outer reinforcement all are separately fixed in the upper end cover 1 and bottom end cover 2 of ring-type at two ends about in the of 4.The bar number of reinforcement can be acquired according to demand.
When air draught power is big, reinforcement can play the intensity that strengthens the high negative pressure Air Filter Filter Core, improves the anti-pressure ability of filter core, makes the high negative pressure Air Filter Filter Core under the bigger situation of air draught power, also be difficult for producing distortion, the filtration of the higher production line that can meet the demands.
