Description
Technical field
The invention belongs to the device removing incrustation, be specifically related to a kind of rotary kiln for calcium aluminate powder.
Background technology
The raw material of calcium aluminate powder is made up of Wingdale and bauxitic clay, and aluminium vanadine and Wingdale enter rotary kiln high-temperature calcination after fragmentation, and the agglutinating matter of formation then makes calcium aluminate powder after ball milling, base, calcining and grinding.Calcium aluminate powder, mainly as the raw material of polymerization filter water purification agent, high-efficiency concrete expansion admixture and refractory castable, has now been widely used in the fields such as chemical industry, environmental protection, sewage disposal.
Operationally, the impurity of the ash content that part material and imperfect combustion dyestuff produce and the inner low melting point of Wingdale is sintered together rotary kiln, and constantly rolling forms bulk and is cemented in the inwall of rotary kiln, forms " ring formation ", " dross ".Ring formation causes the rotary kiln bed of material uneven, and effective cross section in cellar for storing things is amassed and reduces, rotary system resistance increases, and has a strong impact in cellar for storing things and ventilates, and obstruction material movement, reduces the working efficiency of rotary kiln.
Existing treatment process is normally when after rotary kiln running for some time, and stop rotary kiln, after rotary kiln cools completely, operator enter in rotary kiln, carry out the cleaning work of ring formation in rotary kiln.The shortcoming of this mode is: 1. need the extra workload increasing operator, add cost of labor; 2. during stop and rotation kiln, without finished product output, inefficiency.
Summary of the invention
Object provided by the invention is to provide a kind of rotary kiln for calcium aluminate powder, to reduce the ring formation in rotary kiln.
In order to achieve the above object, the invention provides following scheme: comprise rotary kiln body, drive unit, rolling ring and bearing, rotary kiln body is the cylindrical shell of hollow, rotary kiln body is provided with opening for feed and discharge port, the middle part of rotary kiln body is fixed with transmitting gear, transmitting gear is connected with the output terminal of drive unit, rotary kiln body is fixed with rolling ring, rolling ring can be rolled on bearing, wherein, bearing is provided with groove, groove and rolling ring match, rotary kiln body is toward the downward-sloping 3-5 ° of discharge end, rotary kiln body is provided with the clear coil apparatus for clearing up ring formation in the body of revolution cellar for storing things, clear coil apparatus comprises rotating disk, clear circle bar and scraper, the quantity of clear circle bar is at least 2, clear circle bar is symmetrical and be fixed on rotating disk along center of turntable, and scraper is fixed on and encloses clearly on bar, and the free end of clear circle bar is drill bit, the feed end of rotary kiln body is provided with sealing cover, sealing cover comprises cover plate and 2 pieces of flaps, and the center of cover plate is provided with the through hole that aperture is less than the diameter of flap, and cover plate is between 2 pieces of flaps, flap is provided with through hole, and the top of through hole is also hinged with baffle plate.
Principle of the present invention and beneficial effect are:
Rotary kiln body rotates under the drive of drive unit, clear circle bar enters in rotary kiln by the through hole on flap, rotate rotating disk, clear circle bar is driven to rotate in rotary kiln, under the external force of clear circle bar, ring formation is disintegrated, and rotates, finally discharge from the discharge port of rotary kiln body in rotary kiln body with raw material.
The middle part of rotary kiln body is fixed with transmitting gear, and transmitting gear is connected with the output terminal of drive unit; Gear and the transmitting gear of the output terminal of drive unit engage each other, and band nutating gear rotates, then drive rotary kiln body to rotate, geartransmission is steady, reliable operation.Rotary kiln body is fixed with rolling ring, and rolling ring can be rolled on bearing, and bearing is provided with groove, and groove and rolling ring match; Groove in bearing increases the contact area with rolling ring, reduces rotary kiln body stress concentration.Rotary kiln body is toward the downward-sloping 3-5 ° of discharge end; The inclination number of degrees are too high, then can reduce the time that raw material stops in rotary kiln, and not exclusively, the inclination number of degrees are too low in reaction; Then can increase the time that raw material stops in rotary kiln, decrease working efficiency.
Cleaning plant is for clearing up the ring formation in rotary kiln; The quantity of clear circle bar is at least 2, and clear circle bar is symmetrical and be fixed on rotating disk along center of turntable; Clear circle bar is when rotating, and the easily larger vibration of generation and skew, many are enclosed clearly bar centrosymmetry and arrange the skew can well offset each other, and meanwhile, after the quantity increase of clear circle bar, cleaning effect is better.Scraper is fixed on and encloses clearly on bar; Scraper can cut the ring formation of rotary kiln body sidewall, increases cleaning scope.The free end of clear circle bar is drill bit; When ring formation too much blocked up time, drill bit to ring formation cleaning get up to be more prone to.The feed end of rotary kiln body is provided with cover plate and 2 pieces of flaps, and the center of cover plate is provided with the through hole that aperture is less than the diameter of flap, and cover plate is between two pieces of flaps; Cover plate and flap combine, then can close feed end, and two flaps can rotate.Flap is provided with through hole, and the top of through hole is also hinged with baffle plate; Clear circle bar can through through hole thus clear up ring formation, and meanwhile, unfinishedly ensure that scraper enters in rotary kiln, baffle plate is set to hinged, and when scraper enters, baffle plate is opened, and rotate and enclose bar clearly, baffle plate then can be closed automatically, easy and simple to handle.
Compared with traditional rotary kiln for calcium aluminate powder, passing in rotary kiln by enclosing clearly bar, rotating rotating disk, the cleaning work to rotary kiln can being completed, carrying out labor cleaning without the need to stopping rotary kiln; While decreasing cost of labor, also improve the working efficiency of rotary kiln.
Further, be also provided with frame and spacing collar, frame is provided with motor, and motor is connected with rotating disk, and spacing collar is fixed in frame.Driven by motor dial rotation, more laborsaving, efficiency is higher; Spacing collar then effectively can limit the Oscillation Amplitude of channel washer.
Further, rotating disk turn to contrary with turning to of rotary kiln.Rotating backward is the equal of the speed of relative movement adding both, reduces the rotation burden of motor.
Further, the outside surface of clear circle bar and scraper is coated with high-temperaure coating.High-temperaure coating effectively adds the work-ing life of enclosing clearly bar and scraper.
Further, clear circle bar is hollow structure, is provided with working medium in clear circle bar.The clear circle bar of hollow structure forms heat pipe together with working medium, takes full advantage of the Rapid Thermal hereditary property of heat-conduction principle and refrigeration filling, is delivered to rapidly outside thermal source by the heat of thermal objects through heat pipe.Add the heat radiation of enclosing clearly bar, add the work-ing life of enclosing clearly bar.
