Be used to prepare the equipment of spherical shot-like particle
Technical field
The utility model relates to a kind of chemical industry equipment for preparing spherical shot-like particle, particularly relates to a kind of equipment that solid particle contained in the suspension directly is prepared into spherical shot-like particle.
Background technology
The process route that is used to prepare spherical shot-like particle such as ball-shape nickel hydroxide reaches its maturity, process conditions are basically identical also, but it is each has something to recommend him aspect equipment, mainly be around the fast continuous balling-up of particle is constantly improved at present, as Hu Baogang etc. in the patent of its application " a kind of power MH-Ni battery with the production method and the equipment of Nanocrystaline spherical nickel hydroxide " (Chinese patent application number: disclose a kind of equipment that a circulation impels the shot-like particle balling-up that stirs that utilizes 02109600.7), but it exists still and is difficult to control the quick balling-up of particle, sphericity is relatively poor, the unequal defective of size distribution.
The utility model content
The utility model aims to provide a kind of equipment that can make the spherical shot-like particle of preparation of the continuous fast evenly balling-up of particle in the suspension.
The technical scheme that the utility model adopted is as follows:
It comprises reactor, heater, agitator, thermal resistance, seal cover is established on top at reactor, on seal cover, have the insertion agitator, thermal resistance, the aperture that feed pipe is used, aperture and hole count and the pole that needs to insert the agitator in the reactor, the external diameter of thermal resistance and feed pipe is suitable with their total quantity, can allow them insert in the reactor, can keep sealing again, in reactor, be inserted with thermal resistance by these apertures, an agitator and 2-5 feed pipe, the reactor side wall upper part has overfall, it is characterized in that, the reactor inwall is fixed with perpendicular to the retaining at the bottom of the still and pulls, and the upper end of baffle plate and overfall are on same horizontal plane; Paddle number on the described agitator is 2~8 leaves, it is 2,4,6 or 8 that retaining is pulled quantity, the place is equipped with hollow guide shell respectively in the both sides paddle, guide shell should be tried one's best near paddle under the condition that guarantees the clog-free agitated liquid of paddle energy, purpose is to increase the time of staying of suspension liquid in reactor as far as possible, makes the uniform particles balling-up.
In order to make easier balling-up of particle and sphericity round, size distribution is more even, and product quality is better, and the paddle number on the described agitator is good with the 4-6 leaf, and it is good with 4 or 6 that retaining is pulled quantity.
During the utility model work, agitator is the high-speed stirred suspension liquid in reactor, makes when the interior liquid at high speed of reactor flows, the grain that suspends is constantly pulled high-speed impact with retaining, impel particle balling preparation, spherical shot-like particle is after reaching certain density, outside overfall overflows reactor.
The utility model can be when carrying out chemical reaction, and the particle that reaction is generated becomes ball shape fast, and sphericity is better, even particle size distribution.
Description of drawings
Accompanying drawing is the longitudinal cross-section schematic diagram that is used to prepare ball-shape nickel hydroxide equipment one embodiment of the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to accompanying drawing, it comprises reactor 1, automatically controlled heater 2, agitator 3, thermal resistance 4, establish seal cover 5 on the top of reactor, on seal cover, offer 5 apertures, (feed tube is 3 to insert thermal resistance 4, agitator 3 and feed tube 6 by these apertures in the reactor cylindrical shell, all do not draw among aperture and the feed tube figure), the paddle 9 of agitator 3 is four leaves; Reactor cylindrical shell 1 inwall is fixed with perpendicular to the retaining at the bottom of the still pulls 7, and quantity is four (only drawing among the figure); Have overfall 8 on reactor cylindrical shell 1 sidewall, the upper end of aperture position and baffle plate 7 is on same horizontal plane; At paddle place, the both sides of agitator 3 hollow guide shell 10 is installed respectively.
During the preparation ball-shape nickel hydroxide, suspension in the agitator 3 high-speed stirred reactors 1, make when reactor 1 interior liquid at high speed flows, the grain that suspends constantly with perpendicular to the retaining at the bottom of the still is pulled 7 high-speed impacts, make particle balling preparation, after spherical shot-like particle reaches certain density, just overflow from overfall 8.
The purposes of present embodiment is not limited to the preparation of ball-shape nickel hydroxide, also can be used for the preparation of other similar products.
