Abstract
The utility model discloses a multi-layer filter screen, comprising a filter screen body; the filter screen body consists of three filter screen layers mutually sheathed from inside to outside; the three filter screen layers are a filter screen at the outermost layer, a filter screen at the secondary outer layer and a filter screen at the inner layer from inside to outside respectively; each of the filter screens at the outermost layer, the secondary outer layer and the inner layers is composed of a side wall and a mesh enclosure at the bottom of the side wall, the distance between the mesh enclosures of two adjacent filter screen layers is more than 2cm, and the sizes of meshes of the mesh enclosures of the filter screens from inside to outside are gradually reduced. According to the multi-layer filter screen, multiple layers of the filter screens are adopted, and the sizes of the meshes of the mesh enclosures of the filter screens are gradually reduced, so that sewage is ensured to flow smoothly, and simultaneously impurities are prevented from entering a sewer line.
Description
Technical field
The utility model belongs to the construction drainage technical field, is specifically related to a kind of multiple filtration net.
Background technology
Sewer outlet in the people room all can be used screen pack usually, enters sewer pipe to avoid indoor rubbish.Common in the market screen pack is the single-layer type screen pack, the width of mesh of this screen pack is difficult for determining, if mesh is excessive on the screen pack, impurity is entered, in sewer pipe, form the obstruction that mud causes pipeline in the course of time, if screen pack online microphthalmia, then be difficult for timely effluent sewerage, and impurity can stop up tiny mesh again, causes screen pack to stop up, thereby can not play the effect of draining.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, and a kind of multiple filtration net is provided, and it can either guarantee the smooth and easy discharge of sewage, can guarantee that again impurity can not enter sewer pipe.
The technical scheme that the utility model adopts is: a kind of multiple filtration net, comprise the screen pack body, described screen pack body is made of the three layer filtration net of inside and outside mutual socket, this three layer filtration net is respectively the outermost layer screen pack from outside to inside, inferior outer filter net and internal layer screen pack, described outermost layer screen pack, inferior outer filter net and internal layer screen pack all are that the guard bottom sidewall and sidewall constitutes, sidewall between the two-layer adjacent screen pack is provided with internal thread and the external screw thread of mutual coupling, distance between the guard of two-layer adjacent screen pack is greater than 2 centimetres, and from inside to outside on every layer of screen pack the mesh size of guard reduce gradually.
As preferably, described guard is nonplanar structure.
As preferably, described guard undulate.
The beneficial effects of the utility model are: because the utility model adopts the multiple filtration net, the mesh size of guard reduces gradually on the screen pack, during draining, sewage at first enters the internal layer screen pack of mesh maximum, have this moment sewage and partial impurities by and enter time outer filter net, the mesh size of dimension outer filter net is little than the upper strata, the partial impurities that has sewage this moment by and enter the outermost layer screen pack, because of the mesh size minimum of outermost layer screen pack, therefore only allow sewage to pass through; Therefore the utility model can avoid impurity to enter sewer pipe when guaranteeing that sewage is smooth and easy and flowing down.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, outermost layer screen pack; 2, inferior outer filter net; 3, internal layer screen pack; 4, sidewall; 5, guard.
The specific embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of multiple filtration net, comprise the screen pack body, described screen pack body is made of the three layer filtration net of inside and outside mutual socket, this three layer filtration net is respectively outermost layer screen pack 1 from outside to inside, inferior outer filter net 2 and internal layer screen pack 3, described outermost layer screen pack 1, inferior outer filter net 2 and internal layer screen pack 3 all are that the guard 5 by sidewall 4 and sidewall 4 bottoms constitutes, sidewall 4 between the two-layer adjacent screen pack is provided with internal thread and the external screw thread of mutual coupling, distance between the guard 5 of two-layer adjacent screen pack is greater than 2 centimetres, and the mesh size of guard 5 reduces gradually on every layer of screen pack from inside to outside, described guard 5 is nonplanar structure, and it can be waveform or other nonplanar structure form.
Because the utility model adopts the multiple filtration net, the mesh size of guard 5 reduces gradually on the screen pack, during draining, sewage at first enters the internal layer screen pack 3 of mesh maximum, have this moment sewage and partial impurities by and enter time outer filter net 2, the mesh size of dimension outer filter net 2 is little than the upper strata, the partial impurities that has sewage this moment by and enter outermost layer screen pack 1, because of the mesh size minimum of outermost layer screen pack 1, therefore only allow sewage to pass through; Therefore the utility model can avoid impurity to enter sewer pipe when guaranteeing that sewage is smooth and easy and flowing down.
And be threaded between the two-layer adjacent screen pack, the user can arbitrarily change the distance between them as required, or arbitrarily removes and installs, and is very convenient and practical.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
Claims (3)
1. multiple filtration net, comprise the screen pack body, it is characterized in that: described screen pack body is made of the three layer filtration net of inside and outside mutual socket, this three layer filtration net is respectively outermost layer screen pack (1) from outside to inside, inferior outer filter net (2) and internal layer screen pack (3), described outermost layer screen pack (1), inferior outer filter net (2) and internal layer screen pack (3) all are guard (5) formations by sidewall (4) and sidewall (4) bottom, sidewall (4) between the two-layer adjacent screen pack is provided with internal thread and the external screw thread of mutual coupling, distance between the guard (5) of two-layer adjacent screen pack is greater than 2 centimetres, and from inside to outside on every layer of screen pack the mesh size of guard (5) reduce gradually.
2. multiple filtration net according to claim 1, it is characterized in that: described guard (5) is nonplanar structure.
