Abstract
Description
Technical Field
[0001] The utility model belongs to the field of chemical production technical equipment, and particularly relates to a material transfer and filtration device. Background Art
[0002] In titanium dioxide finished product equipment, the slurry after surface treatment needs to be transferred and stored. During the transfer and storage process, a vibrating screen is used for screening, filtering, and grading to separate particles of different particle sizes. By adjusting the amplitude and frequency of the vibrating screen, the screening effect and grading particle size of the slurry are controlled to achieve precise screening of the slurry. In the prior art, the slurry is directly pumped into the vibrating screen directly above by a centrifugal pump through a pipeline and splashes onto the screen mesh. Because the slurry impacts the screen mesh concentratedly during feeding, the screen mesh is frequently damaged, losing the original function of the equipment, the screening effect is not good, and it is difficult to control the content of impurities in the material. Summary of the Invention
[0003] The purpose of the utility model is to avoid the deficiencies of the existing feeding technology and provide a material transfer and filtration device.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a material transfer and filtration device, including a slurry tank and a vibrating screen, characterized in that: the discharge port of the slurry tank is connected to a centrifugal pump, the discharge port of the centrifugal pump is connected to a conveying pipe, a short connection for clearing blockage is provided in the horizontal section in the middle of the conveying pipe, the vertical section at the end of the conveying pipe is connected to a material distributor through a flange, and a vibrating screen is arranged below the material distributor.
[0005] The material distributor includes a flange and a material distribution plate; a short pipe is fixedly connected to the flange, a material distribution plate matching with the flange is fixedly arranged on the bottom surface of the flange, and a sealing gasket with adjustable thickness is arranged between the flange and the material distribution plate.
[0006] Corresponding bolt holes for connecting and fixing the two are opened on the flange and the material distribution plate; a plurality of discharge holes are evenly opened on the material distribution plate.
[0007] The connecting short pipe has the same diameter as the conveying pipe, and the material distributor is connected to the end of the conveying pipe through the connecting short pipe.
[0008] The material distributor is correspondingly arranged directly above the screen mesh on the vibrating screen.
[0009] The sealing gasket is made of FRPP material.
[0010] A check valve and a control valve are arranged on the pipe section of the conveying pipe at the outlet of the centrifugal pump.
[0011] Advantages of the utility model: The overall design is simple, and the operation is simple and convenient. The designed material distributor makes the slurry disperse and spray out on the vibrating screen mesh, reducing the impact and prolonging the service life of the screen mesh. It is convenient for installation and maintenance, reducing the waste of energy and materials caused by equipment maintenance. The short circuit set can regularly clean the pipeline, prevent blockage, and ensure the material homogenization effect. Brief Description of the Drawings
