Embodiment 1

[0036] see Figure 1 to Figure 10 , the present invention provides a technical solution: a rotary drum filter for processing by-products of titanium dioxide production, comprising a pressurized chamber 1, the outer walls of both sides of the pressurized chamber 1 are provided with holes, and the two holes are A rotatable rotating disk 7 is installed, and the opposite surfaces of the two rotating disks 7 are jointly fixed with a plurality of connecting plates 13 distributed in a ring shape. The outer wall of each connecting plate 13 is equipped with a filter assembly, and the outer wall of each connecting plate 13 Both are fixed with a drain pipe 15 that communicates with the filter assembly, and the outer walls on the opposite sides of the two rotating disks 7 are equipped with a drain assembly and a backwash assembly.

[0037]The outer wall of the pressurized cabin 1 is connected with an air intake pipe 3 for inflating the pressurized cabin 1, the bottom of the pressurized ca...

Embodiment 2

[0061] Different from the first embodiment, the movement of the adjusting plate 33 can also be controlled by driving the telescopic rod, so that the adjustment between the adjusting plate 33 and the mounting plate 9 is more stable.

[0062]To sum up, through the continuous rotation of the rotating disk 7, the filter element 8 will be immersed in the slurry, and the titanium gypsum will be filtered at the same time. Prevent the solid phase sedimentation of the titanium gypsum in the slurry, and then when the filter element 8 rotates to the top of the collecting tank 18, the titanium gypsum attached to it will be blown off by the reverse blowing pipe 6, and fall into the collecting tank for collection. At the same time, the movement of the scraping sleeve 10 can further scrape off the titanium gypsum remaining on its surface, so that the filter element 8 can enter the slurry again to maintain its filtering effect.

Abstract

The invention discloses a rotary drum filter for treating titanium dioxide production byproducts and a using method, the rotary drum filter comprises a pressurizing cabin, holes are formed in the outer walls of the two sides of the pressurizing cabin, rotatable rotating discs are installed in the two holes, a plurality of annularly-distributed connecting plates are jointly fixed to the opposite faces of the two rotating discs, and the connecting plates are fixed to the outer walls of the two sides of the pressurizing cabin. The outer wall of each connecting plate is provided with a filtering assembly, the outer wall of each connecting plate is fixedly provided with a drainage pipe communicated with the corresponding filtering assembly, and the outer walls of the opposite surfaces of the two rotating discs are provided with liquid drainage assemblies and back flushing assemblies. Compared with an existing rapid filter press for filtration, the titanium gypsum filter press has the advantages that pressure squeezing is not used, so that damage to the filter assembly is small, maintenance of the filter assembly is simpler, a filtered titanium gypsum filter cake is loose, production efficiency is remarkably improved, and production cost is reduced; although the water content reaches 42%, compared with a filter cake obtained after pressure squeezing, the filter cake is easy to air-dry and is more popular.

Description

technical field [0001] The invention relates to the technical field of titanium dioxide production, in particular to a rotary drum filter for processing by-products of titanium dioxide production and a method of using the same. Background technique [0002] Titanium gypsum calcium sulfate is a by-product of titanium dioxide production. It can be used in cement production as a retarder, and can also be supplied to brick factories to produce bricks. 10-35% to facilitate transportation and feeding. [0003] At present, the traditional ordinary diaphragm filter press can only reach 1.2MPA of pressing pressure, the cycle takes 2 hours, the moisture content is as high as 50%, and the output is only 2.5-3.0 tons per machine. The efficiency is particularly low and the energy consumption is large. Later, the quick filter press was gradually used instead of the ordinary filter press, which greatly improved the efficiency. The pressing pressure can reach 1.7MPA, the cycle only takes 2...
