Abstract
The utility model discloses a cicatrisation recovery utilization system, in particular to a cicatrisation recovery utilization system on washing groove and sedimentation groove of sub-groove. A cicatrisation recovery utilization system is composed by: a milling machine milling the cicatrisation and lye, a last stage slurry flash-pot connected with the milling machine. The utility model can effectively recover the alumina and additive alkali in the cicatrisation, eliminate the impurity therein and can implement the effective recovery, and effectively utilize the remaining heat in the dissolving system and save energy.
Description
Technical field
The utility model relates to a kind of recycling system that scabs, and refers more particularly to the rinse bath of seed precipitation tank and the recycling system that scabs on the subsider.
Background technology
In production processes such as existing aluminum oxide, especially in the process of alumina producing Bayer process, the generation that on the cell wall of the rinse bath of seed precipitation tank and subsider, scabs, thickness can reach about 30cm.So both reduce the cycle efficiency of system, reduced the useful volume of cell body again, thereby reduced the throughput of system.Because this comparatively robust that scabs, need could clear up from cell body with the high pressure cleaning pump, if directly in such system of joining that scabs, to badly influence normal production, if not recycling this part scabs, reduce the rate of recovery of full factory aluminum oxide, thereby improved production cost.Pressure is boiled digestion series simultaneously has a lot of UTILIZATION OF VESIDUAL HEAT IN incomplete, causes the flash distillation water yield of the dilution trap of stripping to increase, and the material level fluctuation is big, the digestion series instability.
The utility model content
It is effectively to utilize the waste heat of digestion series that the utility model provides the recycling system that scabs, purpose in order to address the above problem exactly, and the recovery that will scab.
In order to solve the problems of the technologies described above, the utility model is to realize like this.
A kind of system that scabs and recycle is made of following structure: the grinding machine that will scab and grind with alkali lye, the final stage slip flash-pot that is connected with grinding machine.
Described scabbing is connected with grinding machine through transfer roller.
Described transfer roller is an endless belt conveyor.
Described alkali lye is connected with the inlet of grinding machine through lye pump.
Described grinding machine is connected with slurry vessel.
Described slurry vessel is connected with final stage slip flash-pot by high-pressure delivery pump.
The utility model has the advantages of:
Aluminum oxide and attached alkali during the utility model can efficient recovery scabs are removed impurity wherein, reach the efficient recovery that scabs, and can effectively utilize the waste heat of digestion series again, save energy.
Description of drawings
Fig. 1 is the scab structural representation of recycling system of the utility model.
Among the figure: 1, scab; 2, transfer roller; 3, alkali lye; 4, lye pump; 5, grinding machine; 6, slip; 7, slurry vessel; 8, transferpump; 9, final stage slip flash-pot.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the system that the utility model scabs and recycles, constitute by following structure: scab 1 for washing down from seed precipitation tank or subsider with scavenging pump, scabbing of washing down 1 delivered to the inlet of grinding machine 5 by transfer roller 2, transfer roller 5 is an endless belt conveyor, alkali lye 3 is delivered to the inlet of grinding machine 5 by lye pump 4, with 1 grinding machine 5 that grinds with alkali lye 3 that scabs, slip 6 after grinding machine 5 grinds flows automatically to slurry vessel 7, slurry vessel 7 is delivered to final stage slip flash-pot 9 by high-pressure delivery pump 8 with slip, on the slurry vessel 7 bleeder valve is set.
Principle of work of the present utility model is as follows: scab 1 for washing down from seed precipitation tank or subsider with scavenging pump, scab 1 with what wash down, being delivered to the alkali lye 3 of coming with conveying in the grinding machine 5 mixes, scab and 1 deliver in the grinding machine 5 by transfer roller 2, transfer roller 2 is an endless belt conveyor, alkali lye 3 is the qualified alkali lye behind the alkali liquor preparing, alkali lye 3 is to be delivered to grinding machine 5 inlet by lye pump 41 to mix with scabbing, grinding machine 5 is a ball mill, ball mill pellet volume ratio is controlled at 1:1～3, and alkali lye 3 is 1:1～1.5 with 1 the weight ratio of scabbing; To scab and 1 in grinding machine 5, grind with alkali lye 3; Grinding is one section open type; Slip 6 after grinding is from flowing in the slurry vessel 7; Slip 6 in the slurry vessel 7 is delivered to by transferpump 8 and is pressed in the final stage slip flash-pot 9 that boils in the stripping operation, and transferpump is a high-pressure delivery pump, utilizes the waste heat of flash-pot to make aluminium hydroxide and alkaline reaction generation sodium aluminate solution in scabbing enter system.
Claims (6)
1, the recycling system that scabs is characterized in that it is made of following structure: the grinding machine that will scab and grind with alkali lye, the final stage slip flash-pot that is connected with grinding machine.
2, the recycling system that scabs according to claim 1 is characterized in that described scabbing is connected with grinding machine through transfer roller.
3, the recycling system that scabs according to claim 2 is characterized in that described transfer roller is an endless belt conveyor.
