Abstract
The utility model relates to a conical air filter cylinder which comprises an upper end fixing ring, a lower end fixing ring, and a piece of filtering cloth connected between the upper end fixing ring and the lower end fixing ring, wherein the diameter value of the upper end fixing ring is larger than that of the lower end fixing ring. The conical air filter cylinder takes the shape of an inverted round platform, and when impurities are stopped by the piece of filtering cloth, the probability of dropping out is high, so that the conical air filter cylinder can be used for filtering air efficiently even after long time use.
Description
Technical field
The utility model relates to the air filtration technology, relates in particular to a kind of conical air filter cylinder.
Background technology
Common air filter cylinder is for cylindrical, but conical filter cylinder some problems occur in actual use meeting.Because filter cloth is to be collapsed shape respectively in the filter cylinder periphery, along with the long-time use of filter cylinder, the dust impurity of filtration is deposited on the filter cloth of filter cylinder periphery easily, causes the filter efficiency of filter to descend.
The utility model content
The utility model provides a kind of conical air filter cylinder to the above-mentioned defective of prior art, can avoid filter to use the back filter efficiency to descend for a long time.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:
A kind of conical air filter cylinder comprises upper end retainer plate, lower end retainer plate, is connected in the filter cloth between upper end retainer plate and the lower end retainer plate, and said upper end retainer plate directly is worth greater than the lower end retainer plate and directly is worth.
Can find out that from above technical scheme the utility model upper end retainer plate directly is worth greater than the lower end retainer plate and directly is worth, and makes filter cylinder be inverted truncated conical shape.When filter cylinder filters; When impurity was blocked by filter cloth, because filter cylinder is inverted truncated conical shape, the impurity below did not have the structure of support impurity; Make impurity down drop easily, so also just make the utility model through filtered air efficiently still after using for a long time.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Below in conjunction with the specific embodiment the utility model is done further detailed explanation.
A kind of conical air filter cylinder comprises upper end retainer plate 1, lower end retainer plate 2, is connected in the filter cloth 3 between upper end retainer plate and the lower end retainer plate, and the upper end retainer plate directly is worth greater than the lower end retainer plate and directly is worth.
Above-mentioned specific embodiment is purpose, characteristic and the effect that is used for specifying the utility model; For the personage who is familiar with this type of skill; According to above-mentioned explanation, possibly do part change and modification to this specific embodiment, its essence does not detach the spiritual category person of the utility model; All should be included in the claim of this case suitable first Chen Ming.
Claims (1)
1. a conical air filter cylinder comprises upper end retainer plate, lower end retainer plate, is connected in the filter cloth between upper end retainer plate and the lower end retainer plate, it is characterized in that said upper end retainer plate directly is worth greater than the lower end retainer plate and directly is worth.
