Abstract

The utility model discloses a sewage filter device mainly consisting of a main box body and a filter tank. The main box body is provided with a sewage inlet and a sewage outlet; the filter tank with two stages above is arranged in the main box body; communicated drainage grooves are arranged between every stage of filter tanks and are connected with the sewage inlet and the sewage outlet of the main box body at the same time; each stage of filter tank is provided with a filter screen array on both left and right sides of the drainage groove; the filter screen array and the filter tank wall are arranged at intervals and form an annular drainage way together with the drainage groove; the filter screen array is formed by setting more than one bag-type filter screen at intervals; and the specification of the bag-type filter screen from the first stage to the last stage of the filter tank is increased progressively by 100-300 meshes. Compared with the prior art, the sewage filter device has reasonable design and good sewage processing effect, reduces the disposing cost and greatly improves the economic benefit.

Description

A kind of dirt filter

Technical field

The utility model relates to a kind of paper making equipment, especially refers to the filter of papermaking dirt.

Background technology

The dirt of paper-making industry pollution at present is still comparatively serious, and the processing of dirt is still an environmental protection difficult problem that allows of no optimist.How economic, efficient, stable waste water in the solution paper-making process, the emission problem of waste material are the problems of the long-term uninterrupted research of paper industry.

The utility model content

At the deficiencies in the prior art part, the utility model provides a kind of dirt filter simple in structure.This device operation process is stable, and the dirt processing cost is low.

For achieving the above object, technical solutions of the utility model are:

A kind of dirt filter, it mainly has the main box of dirt inlet port and Sewage outlet by one and is arranged in this main box the filtering ponds more than the two-stage forms.Have the drainage trough that communicates between every grade of filtering ponds, this drainage trough connects the dirt inlet port and the floss hole of main box simultaneously; Every grade of filtering ponds are provided with the screen pack array in the described drainage trough left and right sides, described screen pack array is provided with at interval with the filtration pool wall, and forming the ring-type sluice way jointly with drainage trough, described screen pack array is provided with at interval by more than one bag type filtering net and forms.

One-level filtering ponds to the bag type filtering network planning lattice in the final stage filtering ponds increase progressively the order number step by step by the 100-300 order.

The usefulness of technique scheme is:

The utility model is by two filtering ponds classified filtering dirts more than the unit, and the left and right sides in every grade of filtering ponds is respectively arranged with the bag type filtering net, and the order number of this bag type filtering net increases progressively in regular turn step by step.In the time of in dirt enters main box, dirt flows into the next stage filtering ponds along the ring-type sluice way behind the bag type filtering net filtration, after the floss hole discharge of main box.Compared with prior art, dirt filter of the present utility model is reasonable in design, and the dirt treatment effect is good, and processing cost reduces, and has promoted economic benefit greatly.

Description of drawings

Fig. 1 is the utility model structural representation.

The specific embodiment

The utility model now is described in conjunction with the accompanying drawings and embodiments.

A kind of dirt filter as shown in Figure 1, it mainly has the main box 1 of dirt inlet port 11 and Sewage outlet 12 by one and is arranged at these filtering ponds 2 more than main box 1 interior two-stage forms.Every grade of 2 of filtering ponds have the drainage trough 3 that communicates, and this drainage trough 3 connects the dirt inlet port 11 and the floss hole 12 of main box 1 simultaneously.

Every grade of filtering ponds 2 are provided with the screen pack array in described drainage trough 3 left and right sides, described screen pack array is provided with at interval with the filtration pool wall, and form ring-type sluice way 4 jointly with drainage trough, described screen pack array is provided with at interval by more than one bag type filtering net 5 and forms, and its one-level filtering ponds to the bag type filtering network planning lattice in the final stage filtering ponds increase progressively the order number step by step by the 100-300 order.

Claims

1. dirt filter, be characterised in that: it mainly has the main box of dirt inlet port and floss hole by one and is arranged in this main box the filtering ponds more than the two-stage forms, have the drainage trough that communicates between every grade of filtering ponds, this drainage trough connects the dirt inlet port and the floss hole of main box simultaneously; Every grade of filtering ponds are provided with the screen pack array in the described drainage trough left and right sides, described screen pack array is provided with at interval with the filtration pool wall, and forming the ring-type sluice way jointly with drainage trough, described screen pack array is provided with at interval by more than one bag type filtering net and forms.

2. a kind of dirt filter as claimed in claim 1 is characterised in that: one-level filtering ponds to the bag type filtering network planning lattice in the final stage filtering ponds increase progressively the order number step by step by the 100-300 order.
