Abstract
The utility model relates to a cylindrical preliminary cleaning separator, which comprises a screen cylinder capable of rotation. The rotating shaft axis of the screen cylinder is horizontally equipped. The screen cylinder comprises a left end part and a right end part. A material inlet for conveying materials to be screened is equipped on the right end part of the screen cylinder. A material outlet for removing foreign materials is equipped on the left end part of the screen cylinder. The inner wall of the screen cylinder is provided with spiral material guiding grooves which extend along the screen cylinder rotating shaft axis direction. Screening channels are formed inside the screen cylinder. Screen holes which only permit a passage of the clean materials are opened on the inner wall of the screen cylinder. The materials to be screened enter the screen cylinder from the material inlet and are screened through the screening channels. The clean materials are screened out of the screen holes. The foreign materials pass through the material guiding grooves and then are discharged from the material outlet. By changing the backward material feeding into the forward material feeding, the cylindrical preliminary cleaning separator in the utility model is enabled to prevent an unsmooth material feeding and a material obstruction when the materials enter a chute. Furthermore, when screened, the materials pass through the whole screen cylinder lengthways. Therefore, the screening operation is sufficient.
Description
Technical field
The utility model relates to the big assorted apparatus in the cleaned grain material, particularly relates to a kind of cylinder receiving sieve.
Background technology
At present, the cylinder receiving sieve generally is applicable to the grain material after the results, and the impurity cleaning such as corn, wheat, paddy rice, soybean etc. separates clean grain and impurity according to density, thickness and the diameter of this material.Its technological process is: raw grain enters hopper and flows into screen drum automatically by chute, carries out screen in screen drum, falls into material outlet, then stays in the screen drum and enter big assorted outlet greater than sieve aperture eyelet big assorted less than the material of sieve aperture eyelet.
In general, the cylinder receiving sieve is good for big assorted cleaning effect, and the dust removal rate height makes and do not contain intact full particle or clean material in big the mixing.But because cylinder receiving sieve charging is to be introduced into the screen drum inboard by chute, outwards moved by the inboard, its materials flow is " ∠ " type backward feed again.Its shortcoming is the easy putty in charging chute place, causes material fully not enter and carries out screen in the screen drum, so cleaning effect is not very good.

Preferably, the right part of described screen drum is provided with first ring flange, be connected with at least four pull bars on described first ring flange, described pull bar fixes by second ring flange behind the left part that extends axially out described screen drum one segment distance of described screen drum.
Further preferably, described pull bar is provided with four; The ring flange and the described right part that are positioned at described right part form the grooved circle, are provided with collet in the described grooved circle.
Preferably, described screen drum bottom is provided with a pair of support roller, and a pair of described support roller is arranged on described right part.
Preferably, the right part of described screen drum is connected with hopper, and the outlet of described hopper is connected by chute with the feeding mouth of described screen drum.
Further preferably, described chute exit is provided with the refining door.
Because the technique scheme utilization, the utility model compared with prior art has following advantage and effect:
(1), the utility model is improved to forward feed with cylinder receiving sieve " ∠ " type backward feed, the putty in the time of effectively having avoided material to enter chute is not smooth;
(2), material flow has been removed big assorted in the material efficiently, fully through the length of whole screen drum during screen.
