Abstract
A kind of ardealite calciner belongs to ardealite calcining field, including feed inlet, outer cylinder, inner cylinder, discharge port；It further include dispersing device；The feed inlet is arranged in outer cylinder one end, is connected to outer tube inner chamber；The outer cylinder is cylindrical barrel, and setting is all outer tube, concentric with inner cylinder；The inner cylinder setting is cylindrical barrel body in outer barrel, concentric with outer cylinder；Outer cylinder is connect with inner cylinder by connecting plate, in the tail portion of outer cylinder and inner cylinder, there is charging centrum, the ardealite of outer cylinder enters cone and enters interior tube inner chamber by the conical surface of cone；With that can prevent the ardealite of conglomeration from entering calcining section, the characteristics of being conducive to the raising of the consistency of product and the stability of product quality.
Description
Technical field
The invention belongs to ardealite calciner field, in particular to a kind of bitubular calcining furnace of ardealite calcining.
Background technique
Ardealite is the byproduct of phosphorous chemical industry enterprise, can not directly apply to building or other industry, a large amount of to stack
Cause environmental pollution and land seizure；With the progress of fixed-end forces technology, the present inventor has formerly invented ardealite calcining
Technology is converted into the high strength gypsum powder that can directly apply to construction, to the money of ardealite by ardealite by calcining
Sourceization utilizes and has opened up new thinking；The calcining of existing ardealite is to be sent into bitubular drum-type calcining furnace using by ardealite, will
Phosphogypsum powder, then by reduction cladding, forms high-strength building gypsum powder through high-temperature calcination；In use, calcining is used
Bitubular drum-type calcining furnace need from outer cylinder to enter ardealite, preheated by outer cylinder, into inner cylinder, in inner cylinder end using spraying
Flame is contacted with ardealite and is calcined by stove, makes phosphogypsum modification；When ardealite is transported from the outer cylinder of calcining furnace to inner cylinder
When, since outer cylinder temperature is lower, meanwhile, it is big for original ardealite water content, it is easy conglomeration when entering inner cylinder by outer cylinder,
It is unfavorable for the calcining of ardealite, because ardealite is heat proof material, once conglomeration, internal temperature raising is very slow, is just not easy
Achieve the effect that calcining is modified.
Summary of the invention
Existing problem above, the present invention mention the bitubular drum-type calcining furnace used for existing ardealite in use
A kind of ardealite calciner out, it is characterised in that: including feed inlet, outer cylinder, inner cylinder, discharge port；It further include dispersing device；Institute
The feed inlet stated is arranged in outer cylinder one end, is connected to outer tube inner chamber；The outer cylinder is cylindrical barrel, and setting is outer tube
It is week, concentric with inner cylinder；The inner cylinder setting is cylindrical barrel body in outer barrel, concentric with outer cylinder；Outer cylinder and inner cylinder are logical
Connecting plate connection is crossed, in the tail portion of outer cylinder and inner cylinder, there is charging centrum, the ardealite of outer cylinder enters the conical surface that cone relies on cone
Into interior tube inner chamber；The discharge port setting connects in feed inlet phase the same end, the feed inlet and outer cylinder and interior tube inner chamber
It is logical；The dispersing device is mounted on outer cylinder tail portion and is located at outer cylinder to carry out at material conveying to inner cylinder, and outer drum outer wall is fixed connects
It connects, and passes through outer tube wall and extend into outer tube inner chamber, and make to break up blade and be located at outer tube inner chamber；The dispersing device have one with
On be evenly arranged in outer cylinder cross-sectional periphery.
Further, the dispersing device end is stirring blade, is driven and is rotated by motor.
Further, the motor of the dispersing device uses ring rotation power supply mode.
Beneficial effect
The beneficial effects of the present invention are can make the ardealite for entering inner cylinder from outer cylinder be homogenized and break up, reduce phosphorus stone
The birdnesting effect of cream improves the qualification rate of ardealite calcining, is conducive to the calcination parameter for controlling ardealite, further makes to calcine matter
Amount is stablized.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention
1. flame furnace, 2. inner cylinders, 3. feed inlets, 4. discharge ports, 5. outer cylinders, 6. dispersing devices.
Specific embodiment
Technical solution in order to further illustrate the present invention, now in conjunction with Detailed description of the invention a specific embodiment of the invention, such as
Fig. 1 selects in this example motor to drive retarder and then drives the dispersing device of stirring blade as dispersing device 6, selects in this example
With three dispersing devices 6, it is mounted on the tail portion of outer cylinder 5, herein using 1 one end of flame furnace as front, the other end is tail portion；And position
The position of ardealite is transferred to inner cylinder 2 in outer cylinder 5, three dispersing devices 6 are evenly arranged in this cross-sectional circumferential；This setting is special
The situation high suitable for the ardealite moisture content entered in calcining furnace；Chinese patent (the application of earlier application is selected in this example
Number :) calcining furnace flame furnace, inner cylinder, outer cylinder, feed inlet, discharge port, respectively as flame furnace 1 of the invention, inner cylinder 2, into
Material mouth 3, discharge port 4, outer cylinder 5, and installation combination is carried out according to the general mounting means of the industry, it is punched in 5 tail portion of outer cylinder, and
The installation connecting hole of dispersing device 6 is set around hole, selects three groups in this example, the mixing component of dispersing device 6 is deep into
The inner cavity of outer cylinder 5, by the motor reducer of dispersing device 6 in the fixed airtight connection of outer wall of outer cylinder 5, by the drive of dispersing device 6
Dynamic motor is connect with ring-shaped slide power supply unit, and is connect with the control system of ardealite calcination system, and the present invention is just completed
Implementation.
In application, when the ardealite of 5 inner cavity of outer cylinder has clustering phenomena to occur, start dispersing device 6, dispersing device 6 with
While outer cylinder 5 rotates together, blade rotation is broken up in motor drive, will be by the phosphorus stone of dispersing device 6 and its near zone
Cream is quickly broken up, so that the ardealite into 2 inner cavity of inner cylinder is in loose condition (of surface), is heated evenly, convenient for forging for control ardealite
Temperature is burnt, to calcine out the phosphogypsum powder of different components.
