Abstract
The utility model discloses a three-grade auto-evaporator that adopts bauxite steam to directly heat bayer process digestion. A waste steam output port of the auto-evaporator in each grade of the three-grade auto-evaporator and the port of a waste steam delivery pipe of the auto-evaporator in each grade are respectively connected with a conical transition connecting pipe with big and small ports. And the small ports of the two conical transition connecting pipes are respectively connected with a waste steam valve, and two waste steam valves are connected by a connecting pipe. Discharging pipes of the auto-evaporators in the first grade and in the second grade of the three-grade auto-evaporator are provided with empting valves. The utility model has advantages that the utility model processes a discharging plugged pipe easily, the waste steam valve is not easy to be damaged, a sieve plate is not easy to be blocked, and the pan bottom is not easy to be ground to perforate with stable and reliable working performances.
Description
Technical field:
The utility model relates to three grades of flash-pots of a kind of bauxite steam direct heating Bayer process stripping, belongs to the flash-pot technical field of using in the alumina producing.
Background technology:
At present, three grades of flash-pots of existing bauxite steam direct heating Bayer process stripping in use mainly exist several problems: 1, the easy plugging of the discharge nozzle of flash-pot, thus have to stop processing; 2, owing to directly be connected with the exhaust steam transfer lime on the exhaust steam steam output end mouth of every grade of flash-pot by the exhaust steam valve, the gate bore of its exhaust steam valve is generally bigger, and aperture is very little in use, thereby not only cause exhaust steam valve serious wear, and exist shortcomings such as control difficulty, maintenance replacing valve inconvenience, working cost height; 3, to finish diameter generally unreasonable in the sieve plate hole of existing flash-pot, therefore in use be easy to result in blockage and reduce the steam capability of flash-pot, and its sieve plate is easy to produce loosening phenomenon, thereby influences the job stability of flash-pot owing to fixing unreasonable; 4, the abrasionproof cone in the third stage flash-pot the bottom of a pan of existing three grades of flash-pots is easy to be washed away by slip in use, thereby causes that the bottom of a pan is worn through, even the cylindrical shell of grinding away.Therefore existing three grades of flash-pots are still not ideal enough in use.
Summary of the invention:
The purpose of this utility model is: provide a kind of three grades of flash-pots of bauxite steam direct heating Bayer process stripping that the discharging plugging is easy, the exhaust steam valve is not fragile, sieve plate is difficult for obstruction and working stability is reliable and the bottom of a pan is difficult for being worn through of handling, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises three grades of flash-pots (1), all be connected with a tapering transition pipe connecting (3) respectively on the exhaust steam steam output end mouth of every grade of flash-pot of three grades of flash-pots (1) and on the port of the exhaust steam transfer lime (2) of every grade of flash-pot with big portlet, and on the portlet of two tapering transition pipe connectings (3), all be connected with an exhaust steam valve (4), connect by pipe connecting (5) between two exhaust steam valves (4), on the discharge nozzle of the first step of three grades of flash-pots (1) and second stage flash-pot, dispensing valve (6) is housed all; The diameter phi in the sieve plate hole of the sieve plate (7) of every grade of flash-pot of three grades of flash-pots (1) is: 14mm≤φ≤16mm, and sieve plate (7) is connected on the interior fixedly angle steel (10) of flash-pot (1) by depression bar (8) and U-shaped card (9); On the bottom of a pan abrasionproof frame (11) of the third stage flash-pot of three grades of flash-pots (1), be fixed with anti-wear Plate Steel (12), on anti-wear Plate Steel (12), be fixed with back taper liner plate (13).
Owing to adopted technique scheme, the utility model is compared with existing three grades of flash-pots, the utlity model has to handle the advantage that the discharging plugging is easy, the exhaust steam valve is not fragile, sieve plate is difficult for obstruction and working stability is reliable and the bottom of a pan is difficult for being worn through.
Description of drawings:
