Abstract
The utility model relates to filtering equipment of a water treatment industry, in particular to a brush hair filter. The brush hair filter solves the defects of the existing industrial sewage equipment that the filter effect is not perfect, and the cleaning period of a filter net is very short. The technical proposal is that a brush hair filter is composed of a filter housing, a filter cover plate, a water inlet, a water outlet and a filter net; the filter net is composed of an outer layer filter net and an inner layer filter net, and the inner layer filter net is sheathed in the outer layer filter net; the inner layer filter net can have 1-7 layers which are sheathed with each other respectively. The pore diameter of the inner layer filter net is bigger than that of the outer layer filter net. The brush hair filter is chiefly used for filtering the sewage which contains brush hair or fibrous impurity and is generated in the process of brushing in industrial production.
Description
Technical field: the utility model relates to the filter plant of water treatment field, particularly a kind of bristle filter that is mainly used in the sewage water filtration that contains bristle or fibrous impurity that industrial production produces in the process of scrubbing.
Background technology: the filtration of water treatment field be utilize can allow water by and the solid impurity that contains in the trap water reaches the technical process that makes clarification of water purify purpose.Screen pack formula filter plant is made of filter housing, screen pack, detachable cover plate etc., owing to have simple in structure, easy to operate, ratio of performance to price advantages of higher, in water treatment, have very widely and use, when impurity screening is fibrous waste water, have more significant effect.But, generally also there is following shortcoming in well strainer: because existing net formula is filtered into the individual layer filter screen, and the size of most sewage impurity is not of uniform size, make that the selection of filter screen is very difficult, be easy to generate two kinds of situations, the one, filter screen is held back incessantly or is held back few impurities, does not have the effect of filtration; Another kind is that filter screen is very fast blocked, and the filter screen cleaning frequency is very short.
Summary of the invention: the utility model technical issues that need to address are, can filter to contain different big or small bristles or fiber in the sewage, prolong the cleaning frequency of filter screen.
The technical solution of the utility model is: a kind of bristle filter, comprise filter housing, filter cover plate, water inlet, delivery port, filter screen, filter screen is made up of outer filter and inner filter screen, inner filter screen is socketed in the outer filter, inner filter screen can have layer 1-7, socket successively, the inner filter screen aperture is greater than the outer filter aperture.
The beneficial effects of the utility model are, owing to adopted multistorey strainer mesh, make that the impurity of different sizes can be held back by filter screen in the sewage, and more the filter screen aperture reduces gradually owing to adopted from inside to outside, can avoid the very fast blocked phenomenon of filter screen to take place.Filter has processing simple, and easy to install, the filter screen cleaning frequency is longer, and filter effect is stable, is a kind of filter plant that can effectively remove fibrous impurity.
Description of drawings
Fig. 1 is the utility model embodiment 1 cross-sectional view
Fig. 2 is the utility model embodiment 2 cross-sectional view
Among the figure: 1-filter housing, 2-filter cover plate, 3-water inlet, 4-delivery port, 5-outer filter, 6-inner filter screen.
The specific embodiment: embodiment 1, with reference to Fig. 1, a kind of bristle filter, comprise filter housing 1, filter cover plate 2, water inlet 3, delivery port 4, filter screen, filter screen is made up of outer filter 5 and inner filter screen 6, inner filter screen cover 6 is connected in the outer filter 5, and inner filter screen 6 apertures are greater than outer filter 5 apertures.When sewage begins when outwards flow out the inside of filter most, bigger impurity is held back by inner filter screen 6, when impurity is trapped when flowing through outer filter 5 through inner filter screen 6 filtered sewage, the very fast and outer impurity that is trapped connects, and form a multiple layer filter course of forming by the impurity that is trapped between interior outer leaching net and interior outer leaching net jointly, this phenomenon is especially obvious under with the fibrous state that exists at impurity, and this has just been avoided that one deck filter screen is very fast can phenomenon of blocking.
The Specifeca tion speeification of bristle filter is as follows:
Embodiment 2, and referring to Fig. 2, when sewage impurity was complicated, inner filter screen 6 was 3 layers, socket successively between the filter screen, and all the other are identical with embodiment 1.
Claims (3)
1, a kind of bristle filter comprises filter housing, filter cover plate, water inlet, delivery port, filter screen, it is characterized in that filter screen is made up of outer filter and inner filter screen, and inner filter screen is socketed in the outer filter.
2, a kind of bristle filter according to claim 1 is characterized in that inner filter screen can have layer 1-7, socket successively.
3, a kind of bristle filter according to claim 1 and 2 is characterized in that the inner filter screen aperture is greater than the outer filter aperture.
