Abstract
The utility model discloses a kind of automatically cleanings to harrow machine structure, including the Pa Ji mechanism (1) being arranged in subsider, feed liquid conveyance conduit (3) are fixedly connected with it by spot welding side by side in Pa Ji mechanism (1), alkaline delivery pump (2) is connected on feed liquid conveyance conduit (3) top, is located at spot welding at mud scraper external end head in sedimentation trench bottom and connects two slurry spray nozzles (4).This device of the utility model can effectively prevent the formation that red mud scabs, and reduction stops slot maintenance number, and compensating for existing rake machine structure because being scabbed by red mud is influenced to need the deficiency of frequently maintenance and cleaning, greatly reduce subsider O&M cost.Support is provided for alumina producing industry energy conservation synergy.
Description
Technical field
The utility model relates to aluminium electrolytic equipment technical fields, harrow machine structure more particularly, to a kind of automatically cleaning.
Background technique
Red- mud settlement and separation process is critical process in aluminum oxide production process.The design level and controlled level of subsider
Largely determine the items economy and technical indicator of alumina producing, red- mud settlement and separation efficiency and subsider production capacity are oxygen
Where the bottleneck for changing aluminium enterprise expansion scale.
Slurry in subsider settles under the action of flocculant, and sedimentation separates red mud and sodium aluminate solution, sinks
The red mud of drop comes together in sedimentation trench bottom under the action of rake machine, is discharged after compression.The red mud of sedimentation is easy in trench bottom shape
At scabbing, subsider production capacity is reduced, production cost is increased.
At this stage Pa Ji mechanism used in alumina producer can not to red mud scabbing of being formed of slot inner wall and trench bottom into
Row processing, can only carry out removing scar and cleaning by way of periodically stopping slot.Limit and reduce aluminium oxide production capacity, production O&M at
This increase.
Utility model content
The utility model aim is to provide a kind of automatically cleaning rake machine structure for red- mud settlement and separation.The structure has
Automatically cleaning feature can be effectively reduced the formation that red mud scabs, and compensate for existing rake machine structure is influenced to need because being scabbed by red mud
The deficiency frequently to overhaul and clean, reduction stop slot maintenance amount number, greatly reduce subsider O&M cost.
In order to solve this technical problem, the utility model provides a kind of automatically cleaning rake machine structure, including setting is heavy
The Pa Ji mechanism in slot is dropped, feed liquid conveyance conduit is fixedly connected with it by spot welding side by side in Pa Ji mechanism, in feed liquid delivery pipe
Road top connects alkaline delivery pump, is located at spot welding at mud scraper external end head in sedimentation trench bottom and connects two slurry spray nozzles.
Wherein, the Pa Ji mechanism is the original rake machine system of subsider.
Preferably, the alkaline delivery pump be external equipment, plant capacity size and model according to different rake machine specifications into
The pairing of row type selecting.
Preferably, the input of the alkaline delivery pump is slurry supernatant in subsider, is exported as feed liquid conveyance conduit, alkali
Property delivery pump and feed liquid conveyance conduit interface flanged joint.
Preferably, feed liquid conveyance conduit upper port external alkaline delivery pump is welded to connect at lower port with slurry spray nozzle.
Preferably, the spot welding of feed liquid conveyance conduit is fixed in the transmission shaft of Pa Ji mechanism, the support of horizontal shape and rake arms.
Preferably, feed liquid conveyance conduit is by extracting slurry supernatant, to slot inner wall, trench bottom and rake machine outer end cleaning shoe
Place carries out periodic cleaning.
Cleaning method using automatically cleaning rake machine structure is: alkaline delivery pump extracts slurry supernatant in subsider, in alkali
Property delivery pump pump function under, slurry supernatant flow into feed liquid conveyance conduit after, sprayed through slurry spray nozzle, to slot inner wall, slot bottom
It is cleaned at portion and rake machine outer end cleaning shoe, cleaning frequency is monthly 3 times.
The utility model is due to using external alkaline delivery pump, by extracting slurry supernatant, to slot inner wall, trench bottom and
Periodic cleaning, the formation for effectively red mud being prevented to scab are carried out at the cleaning shoe of rake machine outer end.Compared with prior art, which can
The formation that red mud scabs is effectively reduced, reduction stops slot maintenance and wash number, greatly reduces subsider O&M cost, improves
Manufacturing enterprise's economic indicator.
Detailed description of the invention
Fig. 1 is the automatically cleaning rake machine structure structural schematic diagram of the utility model.
Description of symbols: 1- Pa Ji mechanism, 2- alkalinity delivery pump, 3- feed liquid conveyance conduit, 4- slurry spray nozzle.
Specific embodiment
Automatically cleaning provided by the utility model rake machine structure is described in detail below with reference to Fig. 1, is this reality
With novel an optional embodiment, it is believed that those skilled in the art is not changing the spirit of the present invention and interior
In the range of appearance, can it be modified and be polished.
Referring to FIG. 1, it can be seen from the figure that it includes original Pa Ji mechanism 1, alkaline delivery pump 2, feed liquid delivery pipe
3,2, road slurry spray nozzle 4.Pa Ji mechanism 1 is set in subsider.
Feed liquid in alkaline delivery pump input pipe is slurry supernatant, and efferent duct splicing liquid conveyance conduit interface uses flange
Connection.Feed liquid conveyance conduit 3, spot welding are fixed in former rake machine transmission shaft, the support of horizontal shape and rake arms.Feed liquid conveyance conduit 3, upper end
Mouthful external alkaline delivery pump welds slurry spray nozzle 4 at lower port.
When implementation, feed liquid conveyance conduit 3 passes through alkaline delivery pump 2 and extracts slurry supernatant, to slot inner wall, trench bottom and rake
Periodic cleaning is carried out at the cleaning shoe of machine outer end.Cleaning frequency is generally fixed as 3 times monthly.
The specific application example of above only the utility model, there are also other embodiments, all uses for the utility model
The technical solution that equivalent substitution or equivalent transformation is formed, all falls within protection scope required by the utility model.
