Abstract

The utility model discloses a multistage filter device, which comprises a filter barrel and a filter element assembly arranged in the filter barrel, wherein the filter element assembly comprises a plurality of filter screens arranged in parallel along an axial direction of the filter barrel; filtration holes of the filter screens are decreased gradually from top to bottom; stage filtration is carried out through the filter screens; the filter screen holes on the upper part are larger, so that filter residues with smaller particle sizes can penetrate through, and the holes cannot be blocked by the filter residues with large particle sizes easily; and the filter screen holes on the lower part are smaller, so that the secondary filter can be realized, the phenomenon that the filter screens are blocked by the filter residues cannot occur simultaneously, and the filtering speed is effectively improved. In addition, due to the filter barrel with a cone-shaped structure and the filter screens with a frustum structure, the filter screens can be put in and taken out of the filter barrel conveniently, and the residues can be removed conveniently and quickly.

Description

The multistage filtering device

Technical field

The utility model relates to the filter that is used for Separation of Solid and Liquid.

Background technology

Filter is that a kind of filter core that utilizes is directly tackled the impurity in the liquid, removes suspension, particle in the solution, reduces turbidity, to satisfy the equipment of arts demand or other equipment operate as normal of protection production system.

Traditional filter is the single-stage filter normally, and the filtration hole of filter screen must be little of the filter residue that can filter minimum, and just there is the shortcoming of bigger filter residue easy blocking filter screen in this, and the rate of filtration is slow.In addition, also there are shortcomings such as filter residue cleaning inconvenience in existing filter.

To above-mentioned deficiency, need to improve to existing filter, filter screen was difficult for blockedly when it was filtered, and improved the rate of filtration, in addition, also made filter screen be convenient to cleaning.

The utility model content

In view of this, the utility model provides a kind of multistage filtering device, and this device is through improving element kit, and the filter screen that solves existing filter is prone to the blocked slow technical problem of the rate of filtration that causes.

The utility model solves the problems of the technologies described above through following technological means:

The multistage filtering device of the utility model comprises filter vat and the element kit that is arranged in the filter vat, and said element kit comprises a plurality of filter screens that axially are set up in parallel along filter vat, and said filter screen filtration hole from top to bottom reduces gradually.

Further, said filter vat is up big and down small taper, and said filter screen is positioned on the filter vat inwall;

Further, said filter screen is the uncovered taper type filter screen container of big end, and the big end of filter screen container is positioned on the filter vat inwall;

Further, said filter vat inwall is provided for supporting the back-up block of the big end of filter screen container;

Further, the opening part of the big end of said filter screen container is provided with support ring;

Further, on the said support ring hanger is set.

The beneficial effect of the utility model: the multistage filtering device of the utility model, comprise filter vat and the element kit that is arranged in the filter vat, said element kit comprises a plurality of filter screens that axially are set up in parallel along filter vat; Said filter screen filtration hole from top to bottom reduces gradually, filters through a plurality of filter screen extension sets, and superposed filter screen hole is bigger; Can hold the less filter residue of particle diameter passes through; And be difficult for being stopped up by the filter residue of big particle diameter, the filter screen hole that is positioned at the bottom is less, when realizing secondary filter; Can not occur the phenomenon that filter residue stops up filter screen yet, effectively improve the rate of filtration.In addition, the filter screen of the filter vat of pyramidal structure and taper type structure also is convenient to filter screen and is put into and take out filter vat, and it is convenient and swift to remove the gred.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the schematic top plan view of filter screen.

The specific embodiment

Below will combine accompanying drawing that the utility model is elaborated; As shown in the figure: the multistage filtering device of present embodiment; Comprise filter vat 1 and the element kit that is arranged in the filter vat 1, said element kit comprises a plurality of filter screens 2 that axially are set up in parallel along filter vat 1, and said filter screen 2 filtration hole from top to bottom reduces gradually; Through multistage filter screen with the filter residue classification; The bigger filter residue of superposed strainer filtering particle diameter is positioned at the less filter residue of strainer filtering particle diameter of bottom, and big particle diameter filter residue stops up filter screen when having avoided particle diameter to differ bigger filter residue hybrid filtering.

As the further improvement of technique scheme, said filter vat 1 is up big and down small taper, and said filter screen 2 is positioned on filter vat 1 inwall, and the conical inboard wall of filter vat can form effective support to filter screen, makes every grade of filter screen be fixed on different height in the filter vat.

Further improvement as technique scheme; Said filter screen 2 is the uncovered taper type filter screen container of big end, and the big end of filter screen container is positioned on filter vat 1 inwall, forms the filter screen container with certain depth; Can hold more filter residues, and when taking out filter screen filter residue be difficult for to around be scattered.

Further improvement as technique scheme; Said filter vat 1 inwall is provided for supporting the back-up block 3 of the big end of filter screen container; Filter screen is stuck when supporting with the conical inboard wall that prevents filter screen dependence filter vat; Simultaneously, because the filter vat inwall is taper, back-up block can not block yet and be positioned at packing into and taking out of below filter screen.

Further improvement as technique scheme; The opening part of the big end of said filter screen container is provided with support ring 4; Support ring can increase the intensity of filter screen container finish on the one hand; Make filter screen not yielding when the slagging-off handling, support filter screen, also not fragile filter screen through support ring and back-up block effect on the other hand.

As the further improvement of technique scheme, on the said support ring 4 hanger 5 is set, handling when being convenient to clear up.

Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
