Abstract
The utility model discloses equipment for reducing the filtering area of a mother liquor float recovery leaf filter. A tapered mother liquor tank (1) is connected with the leaf filter (2) through a filter cake pump (5). The leaf filter (2) is connected with a filter cake tank (3) and the mother liquor tank (4). The filter cake tank (3) and the mother liquor tank (4) are connected with a third filter cake pump (9) and a fourth filter cake pump (8) respectively. A first filter cake pump (6) and a second filter cake pump (7) are directly connected with the tapered mother liquor tank (1). The filtering area of the leaf filter is greatly reduced, so that the aim of greatly saving equipment investment cost and production and running cost is fulfilled.
Description
Technical field
The utility model relates to the equipment that a kind of mother liquor floating material reclaims, and particularly relates to a kind of equipment that mother liquor floating material reclaims the leaf filter filtration area that reduces.
Background technology
In the traditional mode of production flow process of aluminum oxide, all mother liquors all are sent in the vertical leaf with feeding pump and filter in the taper mother liquor tank.The aluminum hydroxide particles that obtains after the filtration (filter cake) gets into the filter cake groove and decomposes with the 4th filter cake pumping is past, and the mother liquor after the filtration then flows into mother liquor tank.Mother liquor is most of in the groove evaporates toward evaporator station through the 3rd filter cake pumping; Toward water of decomposition spigot dilute hydrogen alumina slurry, rest part then cleans some scavenging pump, valve and associated conduit through the second filter cake pumping toward each mother liquor to a part through the first filter cake pumping.Because all mother liquors all will pass through vertical leaf in the flow process, so the mother liquor amount is very big, the total filtration area of leaf filter is bigger than normal, and leaf filter platform number is on the high side.
Summary of the invention
The utility model is dealt with problems and is: how too much to leaf filter mother liquor inlet amount with leaf filter platform number, a kind of equipment that reduces mother liquor floating material recovery leaf filter filtration area is provided.
The technical scheme of the utility model: the utility model comprises that the taper mother liquor tank is connected with leaf filter through the filter cake pump; Leaf filter is connected with filter cake groove, mother liquor tank; Filter cake groove, mother liquor tank are connected with the 3rd filter cake pump, the 4th filter cake pump respectively, and the first filter cake pump, the second filter cake pump directly are connected with the taper mother liquor tank.
The utility model has reduced the total mother liquor amount through leaf filter, has saved the leaf filter filtration area, thereby has reduced filtration board number.
Description of drawings
Accompanying drawing 1 original equipment structural representation;
Accompanying drawing 2 is the structural representation of the utility model;
1. taper mother liquor tanks among the figure, 2. leaf filter, 3. filter cake groove, 4. mother liquor tank, 5. feeding pump, 6. filter cake pump, 7. filter cake pump, 8. filter cake pump, 9
.The filter cake pump.
Embodiment
Embodiment: as shown in Figure 1, after mother liquor got into taper mother liquor tank 1, wherein a part directly was sent to the water of decomposition spigot with filter cake pump 7; Another part also directly is sent to each mother liquor through filter cake pump 6 and cleans point.Above-mentioned two portions mother liquor accounts for about 1/4 ~ 1/3 of total mother liquor amount.The residue mother liquor is sent to leaf filter 2 through feeding pump 5 and filters.Filtering mother liquor gets into mother liquor tank 4 backs and is sent to the evaporation section evaporation with filter cake pump 8, and filter cake falls into filter cake groove 3 backs and is sent to decomposition with filter cake pump 9.Through this kind novel method, be example to produce 800000 tons of alumina producers per year, per hour can reduce mother liquor floating material and reclaim feeding pump 5 operational throughpuies ~ 300m
3, can reduce leaf filter 2 filtration areas ~ 85m simultaneously
2, so improve and to save a large amount of facility investment expenses and production run cost.
Claims (1)
