Description
Technical field
The utility model belongs to technical field of inorganic chemical industry, is specifically related to a kind of waste ammonia-soda solution settling tank that is used for the soda ash manufacturing.
Background technology
At present; Prepare in the soda ash process in ammonia-soda process; Can produce a large amount of waste ammonia-soda solutions; Usually adopt following method to handle: from the waste ammonia-soda solution (about wt2.85%) of production area through after the desanding in settling tank stiff go filter press to carry out press filtration after becoming the mud of 6%-9%, clear liquid discharge after the overflow of settling tank top supplies with the saltern use.Settling tank all with waste liquid advance continuously, a bucket top clear liquid continuous overflow goes out, mud from the bucket end intermittently sludge discharge way use (every barrel of about one hour spoil disposal once).
Wherein, the waste ammonia-soda solution settling tank is the equipment that makes solid, liquid two-phase initial gross separation in the mixed waste liquor, and operation principle is the gravity effect of leaning on, and the solid particles sediment rapid speed makes it in liquid medium, be deposited to the bottom, discharges then.Usually, the waste liquid settling tank comprises staving, the bucket end and upper bracket, and upper bracket is provided with the cycloidal planetary gear speed reducer drive unit, and the drive unit place is provided with cylindrical central sleeve, and the lower end of drive unit connects central rotating shaft and rake mud frame, and rake mud frame has cleaning shoe.
Existing drive unit is that monolateral reductor drives pinion, drives the central rotating shaft rotation by pinion driving rotational gear wheel, when operation, exists to rotate to receive force unbalance, and the suffered load of pinion is high, problems such as crown serious wear; Do not have sealing device on the cylindrical central sleeve, waste liquid produces a large amount of steam and foam entering gear-box causes corrosion, influences the service life of device; Rake mud frame is an in-line, and cleaning shoe is the 100MM angle bar, and the little stirring in the end of rake mud frame awl is connected by gripper shoe with central rotating shaft welds.
Because settling tank is in actual production, existence is stiff mud problem effectively, is seriously restricting the ability that settling tank disposes waste liquid, the main performance as follows:
1, agitating device intensity difference.For protection equipment (agitating device) is not damaged; The concentration of hydraulic mixture of blowing generally is controlled between the 5%-7% during normal the operation, and the filter cake thickness that filter press produces is at 8-10mm, when concentration of hydraulic mixture rises to 8%-10%; The cake of filter-press thickening is between 12-14 mm; This moment, the electric current of settling tank reductor just began between 8.2-8.8A, to fluctuate, and operating personnel must open to efflux at once and produce after slush pump is had loose bowels concentration of hydraulic mixture again, surpass 9.0A once the discovery electric current rises; Have only hard stop to protect to stir rake and do not damage, wash then the settling tank inspection stir after charging operation again.
2, the waste liquid sedimentation time of settling tank charging is long, settled layer is unstable, overflowing liquid turbidity control difficulty in clarification back is big; It is bad that mud rake is scraped the mud effect, and present waste liquid heads into material to bottom from bucket and goes out qualified mud greatly about 6-7 hour, and the waste liquid amount that obviously charging when normal the operation, often occurs is very big; But the concentration of hydraulic mixture of releasing is more and more lower; Mud rake can not in time be scraped mud to awl drain hole place, the end, causes unnecessary mud amount all to accumulate in bucket, to the reductor electric current is risen suddenly; Operating personnel strengthen the mud emission amount does not have effect yet, is compelled to stop the bucket flushing at last.
3, cause the filter press disposal ability low, the mud of low concentration can only be provided for filter press, filter press filter chamber height is 45mm, and single circulation maximum can be produced the thick filter cake of 30-40 mm, can only maintain about 10mm, and filter press is not had enough to eat, and it is not high to go out power rate.
Summary of the invention
The purpose of the utility model is to propose a kind of improved waste ammonia-soda solution settling tank.
The main technical schemes of the utility model: improved waste ammonia-soda solution settling tank, comprise staving, upper bracket, central rotating shaft and rake mud frame, upper bracket is provided with drive unit; The drive unit place is provided with cylindrical central sleeve; The lower end of drive unit connects central rotating shaft and rake mud frame, and rake mud frame has cleaning shoe, it is characterized in that drive unit is the transmission of biliquid pressure motor; Cylindrical central sleeve is a hermetically-sealed construction; Central rotating shaft is the vertical shelf structure of center rotating cage, and rake mud frame is a cross diclinic support, and the little stirring in the end of rake mud frame awl is that bolt is connected with the center rotating cage.
Usually, the described settling tank of the utility model, cylindrical central sleeve top is that blind plate sealing, bottom are packing box seal; Cylindrical central sleeve top is provided with the pointer that shows that rake mud frame rotates.
Said settling tank is 26m, cleaning shoe width 200mm under the rake mud frame.
Stable more minimizing of settling tank after the utility model improves, operation produces fluctuation, and equipment fault reduces has stablized production.Make the production capacity of filter press be able to promote and the prolongation in service life of slag field simultaneously, reduce recondition expense when improving the filter press operation ratio and going out power rate again.
