Description

Multistage rotary screen
Technical field
The utility model has related to a kind of multistage rotary screen, has particularly related to a kind of multistage rotary screen that can sub-elect various materials.
Background technology
The mesh of present rotary screen all is onesize, and in order to consider the anterior plugging reason easily of rotary screen, often Qian Bu mesh is bigger slightly than the mesh at rear portion sometimes.Therefore can only be divided into that sieve is gone up and two kinds of screenings, and the sieve of other types often there is multilayer.Sometimes need to carry out the two-stage screening with rotary screen, often will will increase belt feeder simultaneously the two poles of the earth are coupled together with two rotary screens, both floor space increased, and will increase conveying equipment simultaneously.Especially when the oversize of rotary screen carries out selection by winnowing since only through the volume differences of one-level screening material apart from bigger, finger stone and assorted soil can appear containing in the plastics in the weak effect of selection by winnowing.
Summary of the invention
Goal of the invention of the present utility model is to solve two kinds of material problems that vary in size that existing multistage rotary screen can only sub-elect, and a kind of multistage rotary screen is provided.
In order to finish goal of the invention of the present utility model, the utility model is by the following technical solutions: a kind of multistage rotary screen of the present utility model, it comprises: the charging belt machine, rotary screen, chute and go out strip, the charging belt machine is contained in an end of rotary screen, wherein: described rotary screen comprises: first rotary screen, second tin roller sieve and the 3rd rotary screen, be followed successively by first rotary screen with respect to the charging belt machine, second tin roller sieve and the 3rd rotary screen, first rotary screen, the lower end of second tin roller sieve and the 3rd rotary screen is equipped with first chute respectively, second chute and the 3rd chute, opening part at first chute is equipped with belt feeder, one end of belt feeder is equipped with first and goes out strip, the opening part of second chute and the 3rd chute is equipped with second respectively and goes out strip and the 3rd and go out strip, is equipped with the 4th in the exit of rotary screen and goes out strip;
A kind of multistage rotary screen of the present utility model, wherein: the mesh size of described first rotary screen is less than the mesh size of second tin roller sieve, and the mesh size of second tin roller sieve is less than the mesh size of the 3rd rotary screen;
A kind of multistage rotary screen of the present utility model, wherein: with respect to the horizontal plane downward-sloping 5-15 ° of described rotary screen.
A kind of multistage rotary screen of the present utility model is compared with existing rotary screen, this utility model is exactly to do the mesh of rotary screen front portion to such an extent that the mesh at less rear portion is done greatlyyer, like this less than the finger stone and the soil of anterior mesh, in the past clan down and by chute and conveyer belt with screenings separately and transfer out, fall by chute and conveyer belt greater than anterior mesh and less than the medium material of rear portion mesh mesh from the rear portion, with medium screenings separately and transfer out, and another kind of oversize material is gone out by conveyor delivery from sieving discharge.Reach a rotary screen like this and just can sub-elect four kinds of materials.Also the mesh of rotary screen front portion can be done to such an extent that the mesh at less middle part is done greatlyyer, the mesh at rear portion is bigger.Become multistage rotary screen.
Description of drawings
Fig. 1 is the forward schematic diagram of a kind of multistage rotary screen of the present utility model;
Fig. 2 bows to schematic diagram for Fig. 1's.
As depicted in figs. 1 and 2, label 1 is the charging belt machine; Label 2 is first chute; Label 3 is first rotary screen; Label 4 is second chute; Label 5 is the second tin roller sieve; Label 6 is the 3rd chute; Label 7 is the 3rd rotary screen; Label 8 is a belt feeder; Label 9 is first to go out strip; Label 10 is second to go out strip; Label 11 is the 3rd to go out strip; Label 12 is the 4th to go out strip.
The specific embodiment
As depicted in figs. 1 and 2, a kind of multistage rotary screen of the present utility model comprises: charging belt machine 1, rotary screen, chute and go out strip, with respect to the horizontal plane downward-sloping 5-15 ° of rotary screen, charging belt machine 1 is contained in an end of rotary screen, rotary screen comprises: first rotary screen 3, second tin roller sieve the 5 and the 3rd rotary screen 7, be followed successively by first rotary screen 3 with respect to charging belt machine 1, second tin roller sieve the 5 and the 3rd rotary screen 7, first rotary screen 3, the lower end of second tin roller sieve the 5 and the 3rd rotary screen 7 is equipped with first chute 2 respectively, second chute 4 and the 3rd chute 6, opening part at first chute 2 is equipped with belt feeder 8, one end of belt feeder 8 is equipped with first and goes out strip 9, the opening part of second chute 4 and the 3rd chute 6 is equipped with second respectively and goes out strip 10 and the 3rd and go out strip 11, is equipped with the 4th in the exit of rotary screen and goes out strip 12.
The mesh size of first rotary screen 3 is less than the mesh size of second tin roller sieve 5, and the mesh size of second tin roller sieve 5 is less than the mesh size of the 3rd rotary screen 7.
Operation principle
The material that is sized enters rotary screen by charging belt machine 1, and thin material is fallen belt feeder 8 and first and gone out on the strip 9 to transfer out through first rotary screen 3 and first chute 2.Slightly thick material falls into second through second tin roller sieve 5 and second chute 4 and goes out strip 10, is transferred away.Thick material drops into the 3rd through the 3rd rotary screen 7 and the 3rd chute 6 and goes out strip 11, is transferred away.The thick material of oversize goes out strip 12 from outlet through the 4th and is output.Go out the material that strip 11 and the 4th goes out on the strip 12 and carry out selection by winnowing going out strip the 10, the 3rd from second respectively this moment again, because the volume of selected material is approaching, the effect of selection by winnowing is just more satisfactory, if be used as various types of garbage disposals, rubble and assorted soil have not just been had in the polybag that is gone out by selection by winnowing etc. again.
More than describing is to explanation of the present utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of spirit of the present utility model, the utility model can be done any type of modification.
