The utility model relates to a kaolin technical field, concretely relates to kaolin filter equipment.

Background

The kaolin has unique physical characteristics, good plasticity and wide application. Traditional filtration of kaolin is through natural precipitation separation impurity, and the filter time is long and the filter fineness is low. Rapid filtration cannot be achieved.

SUMMERY OF THE UTILITY MODEL

The utility model aims at designing a kaolin filter equipment, make it realize shortening the settling time and improve production efficiency.

In order to achieve the above object, the utility model provides a following technical scheme:

a kaolin filtering device comprises a vibrating screen and a sedimentation centrifuge; the vibrating screen is an inclined vibrating screen, and the inclined lower end of the vibrating screen is an impurity outlet end; the inlet end of the collecting tank is communicated with the position right below the impurity outlet end; the collecting tank is obliquely arranged, and the outlet end of the collecting tank is communicated with the collecting tank; the collecting box is positioned outside the filtering tank; the bottom of the vibrating screen is provided with a filtering outlet; the filtering tank is arranged below the filtering outlet; the feed inlet of the sedimentation centrifuge is connected with the filter tank through a pipeline; the liquid outlet end of the sedimentation centrifuge is connected with a next-stage operation device; and a collecting barrel is arranged under the solid outlet end of the sedimentation centrifuge.

Furthermore, the inclined upper end and the left side and the right side of the vibrating screen are provided with baffles, so that impurities of the vibrating screen are prevented from falling into the filter tank when the vibrating screen vibrates.

Further, the interior surface of the collection tank is smooth, helping the impurities to slide off and not accumulate within the collection tank.

Furthermore, the sedimentation centrifuge is a horizontal spiral discharge sedimentation centrifuge, so that fine impurities can be conveniently separated.

Further, the shale shaker is equipped with the three-layer screen cloth just the aperture of screen cloth reduces from last to down in proper order, carries out tertiary filtration through the three-layer screen cloth that sets up different apertures, improves impurity separation effect.

Compared with the prior art, the beneficial effects of the utility model are that: the combined use of the vibrating screen and the sedimentation centrifuge shortens the precipitation time of the raw material, realizes the rapid filtration of the impurities of the raw material and improves the filtration efficiency and the filtration precision.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, only some embodiments, not all embodiments, of the present invention are described. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example (b): a kaolin filtering device comprises a vibrating screen and a sedimentation centrifuge 6; the vibrating screen is an inclined vibrating screen, and the inclined lower end of the vibrating screen is an impurity outlet end; the inlet end of the collecting tank 3 is communicated with the position right below the impurity outlet end; the collecting groove 3 is obliquely arranged, and the outlet end of the collecting groove 3 is communicated with a collecting box; the collecting tank is positioned outside the filtering tank 4; the bottom of the vibrating screen is provided with a filtering outlet 5; a filtering tank 4 is arranged below the filtering outlet 5; the feed inlet of the sedimentation centrifuge 6 is connected with the filter tank 4 through a pipeline 10. The liquid outlet end 11 of the sedimentation centrifuge 6 is connected with a next-stage operation device, and the next-stage operation device is a stirring tank 8; a collecting barrel 7 is arranged right below a solid outlet end 12 of the sedimentation centrifuge 6;

the slope upper end and the shale shaker left and right sides of shale shaker all are equipped with baffle 9, prevent that the shale shaker from having impurity to fall into the filtering ponds when the vibration.

The internal surface of the collecting gutter 3 is smooth, helping the impurities to slide down without accumulating inside the collecting gutter 3.

The sedimentation centrifuge 6 is a horizontal spiral discharge sedimentation centrifuge, and is convenient for separating fine impurities.

The shale shaker is equipped with three-layer screen cloth 2 just the aperture of screen cloth 2 reduces from last to down in proper order, carries out tertiary filtration through the three-layer screen cloth that sets up different apertures, improves impurity separation effect.

The working principle of the embodiment is as follows: raw materials enter into the screen cloth 2 of shale shaker through raw materials pipe 1 on, carry out tertiary filtration through the different aperture screen cloth of three-layer of shale shaker, impurity is fully filtered out and is shaken off along with the vibration of shale shaker and is discharged in collecting vat 3 and collect the case. The filtrate then enters the filtration tank 4 through the filtration outlet 5. The filtrate in the filtering tank 4 enters a horizontal spiral discharging sedimentation centrifuge 6 through a pipeline 10 to further separate fine impurities, and the fine impurities are separated from a solid outlet 12 and enter a collecting barrel 7. And filtrate from the liquid outlet 11 to the next stage of operation.

The utility model has the advantages that: the combined use of the vibrating screen and the sedimentation centrifuge shortens the precipitation time of the raw material, realizes the rapid filtration of the impurities of the raw material and improves the filtration efficiency and the filtration precision.
