Abstract

The utility model discloses a drum screening device, including the support, rotate to set up the first sieve section of thick bamboo on the support, still include the second sieve that connects with first sieve barrel casing tin, be equipped with first sieve mesh on the perisporium of a first sieve section of thick bamboo, be equipped with the second sieve mesh on the perisporium of a second sieve section of thick bamboo, a second sieve section of thick bamboo can a sieve first relatively section of thick bamboo rotates makes first sieve mesh and the second sieve mesh main sieve mesh of formation that interlocks, set up the mounting after the relative second sieve section of thick bamboo of a first sieve section of thick bamboo rotates on a first sieve section of thick bamboo and the second sieve section of thick bamboo, rotating when a second sieve section of thick bamboo and making the size of the main sieve mesh decision screening granule that the crisscross back of second sieve mesh and first sieve mesh formed, when first sieve mesh and second sieve mesh were crisscross, first sieve mesh equalled with second sieve mesh size, consequently this moment main sieve mesh the size equal with first sieve mesh size or second sieve mesh size, when needing adjustment screening granule size, only need to rotate a second sieve section of thick bamboo and after the rotation with a first sieve section of thick bamboo and a second sieve section of thick bamboo is fixed can.

Description

Rotary screen separating device

Technical field

This utility model relates to the screening plant of a kind of building materials waste material, is specifically related to a kind of rotary screen separating device.

Background technology

The Chinese patent that publication number is 203874987U discloses a kind of rotary screen separating device, including rotary screen, described rotary screen is provided with sieve aperture；The axis rotating axle, described rotation axle and described rotary screen be arranged in parallel；Draw hole wheel, described in draw hole wheel be arranged on described rotation axle, described in draw hole wheel have be correspondingly arranged with described sieve aperture draw hole tooth.

This mode is fixing due to the slot size of rotary screen, and the scope of the granular size therefore screened is less.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is in that to provide the rotary screen separating device of a kind of scalable screening granulometric range.

For achieving the above object, this utility model provides following technical scheme: a kind of rotary screen separating device, including support, rotate the first screen drum being arranged on support, also include and the second screen drum of the first screen drum socket, the perisporium of described first screen drum is provided with the first sieve aperture, the perisporium of described second screen drum is provided with the second sieve aperture, described second screen drum can rotate relative to the first screen drum and make the first sieve aperture and the second sieve aperture be staggered to form main sieve aperture, and described first screen drum and the second screen drum arrange first screen drum fixture after the second screen drum rotates.

When the second screen drum rotates the size making the main sieve aperture that the second sieve aperture and the first sieve aperture are formed after interlocking determine screening granule, when first sieve aperture and the second sieve aperture are not staggered, now less with slot size in the first sieve aperture or the second sieve aperture of the size of main sieve aperture is equal, when needing to adjust screening granular size, only need to rotate the second screen drum and after rotation, the first screen drum and the second screen drum be fixed.

Further: described fixture includes some first lockholes being arranged on the first screen drum, the second lockhole being arranged on the second screen drum, plug-in unit also cross the first lockhole and the second lockhole.

Further, described plug-in unit is lock or latch.

Further, described fixture includes the groove being arranged on the first screen drum, can slide and be connected to the bolt of nut along groove through groove and the second screen drum.

Further, described first screen drum is arranged in the second screen drum, is provided with rotating shaft in described first screen drum, and described support arranges a motor, and the output shaft of described motor is fixing with rotating shaft to be connected.

The first screen drum and the second screen drum is driven to rotate by the output shaft rotation of motor.

Overall merit of the present utility model: regulate the size of main sieve aperture by rotating the second screen drum, thus screening the material of different size granule.

Detailed description of the invention

Referring to figs. 1 through Fig. 3, this utility model is described further.

nullEmbodiment one: as shown in Figure 1，A kind of rotary screen separating device，Including support 1、First screen drum 2、Second screen drum 3，Second screen drum 3 is socketed on the first screen drum 2，It is fixed with rotating shaft 6 in first screen drum 2，Support 1 arranges a motor 5，The output shaft of motor 5 is fixing with rotating shaft 6 to be connected，The perisporium of the first screen drum 2 is provided with the first sieve aperture 21，The perisporium of the second screen drum 3 is provided with the second sieve aperture 31，The size of the first sieve aperture 21 is basic equal with the second sieve aperture 31，Second screen drum 3 can rotate relative to the first screen drum 2 and make the first sieve aperture 21 and the second sieve aperture 31 be staggered to form main sieve aperture 4，First screen drum 2 is offered some first lockholes 23、Second screen drum 3 is offered the second lockhole 32，After the first lockhole 23 and the second lockhole 32 align，Plug-in unit 9 adopts latch or lock the first screen drum 2 and the second screen drum 3 to be fixed through the first lockhole 23 and the second lockhole 32.

When rotating the second screen drum 3, pull up plug-in unit 9, after rotation, plug-in unit 9 is inserted through the first lockhole 23 and the second lockhole 32.

Embodiment two: such as Fig. 2-3, with embodiment one the difference is that, first screen drum 2 offers groove 22, bolt 7 traverse groove 22 and the second screen drum 3 attaching nut 8, when the first screen drum 2 and the second screen drum 3 are clamped by the bolt cap that fastening nut 8 makes nut 8 and bolt 7, the first screen drum 2 and the second screen drum 3 are fixed.

First unclamp nut 8 when rotating the second screen drum 3, after rotation, nut 8 is tightened.

The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
