Material transferring and filtering device
Technical Field
The utility model belongs to the technical field of chemical production equipment, and particularly relates to a material transferring and filtering device.
Background
In titanium dioxide finished product equipment, the slurry subjected to surface treatment is required to be subjected to material transfer, and a vibrating screen is required to be used for screening, filtering and grading in the transfer process, so that particles with different particle sizes are separated. The sizing effect and the grading granularity of the sizing agent are controlled by adjusting the amplitude and the frequency of the vibrating screen, so that the sizing agent is accurately screened. In the prior art, slurry is directly pumped into the position right above the vibrating screen through a pipeline by a centrifugal pump and splashed to the screen, and the screen is frequently damaged due to concentrated impact during slurry feeding, so that the original function of equipment is lost, the screening effect is poor, and the content of impurities in the material is difficult to control.
Disclosure of Invention

The material transferring and filtering device is characterized in that a discharge hole of the slurry tank is connected with a centrifugal pump, a discharge hole of the centrifugal pump is connected with a conveying pipe, a horizontal section of the middle section of the conveying pipe is provided with a short circuit for clearing blockage, a vertical section of the tail end head of the conveying pipe is connected with a material homogenizing device through a flange, and the vibrating screen is arranged below the material homogenizing device.
The material homogenizing device comprises a flange and a material homogenizing plate, wherein a short connecting pipe is fixed on the flange, the material homogenizing plate matched with the flange is fixed on the bottom surface of the flange, and a sealing gasket capable of adjusting the thickness is arranged between the flange and the material homogenizing plate.
Corresponding bolt holes for connecting and fixing the flange and the material homogenizing plate are formed in the flange and the material homogenizing plate, and a plurality of discharging holes are uniformly formed in the material homogenizing plate.
The connecting short pipe is equivalent to the pipe diameter of the conveying pipe, and the material homogenizing device is connected with the tail end of the conveying pipe through the connecting short pipe.
The material homogenizing device is correspondingly arranged right above the screen mesh on the vibrating screen.
The sealing gasket is made of FRPP material.
And a check valve and a control valve are arranged on the pipe section of the material conveying pipe at the outlet of the centrifugal pump.
The utility model has the advantages of simple integral design, simple and convenient operation, and the designed material homogenizing device can ensure that the slurry is scattered and sprayed on the screen mesh of the vibrating screen, reduce the impact, prolong the service life of the screen mesh, be convenient to install and maintain, reduce the energy and material waste caused by equipment maintenance, and be provided with a short circuit which can periodically clean the pipeline, prevent blockage and ensure the material homogenizing effect.
