Description

Ceramic powder pelletizing apparatus and production technology
The present invention relates to a kind of ceramic powder pelletizing apparatus and production technology, belong to the Ceramic Production field.
At present; ceramic industry is produced wall brick; floor tile; products such as vitreous brick; all adopt powder granulating technique and relevant device that powder is made particle; be pressed into product by press again; now granulating technique and the equipment that generally adopts has two kinds, and the one, use the spray drying tower granulation, it is that the slip that contains 45% moisture content that the spheroidal graphite machine is worn into is upwards sprayed by the spray drying tower bottom; and be blown into 450-500 ℃ of pressure hot blast downwards by top; the slip that makes it and the spray formation particulate that meets, this method equipment is huge, and investment is many; fuel;; water consumption is big; the technological process complexity; production cycle is long, and the 2nd, adopt the granulation of humidification comminutor, this method comes down to that powder is added water and stirs; inhomogeneous; the surface is crude, and particle is not obvious, even does not have particle; have the big problem of water content equally, and this pellet is only applicable to handpress production.
The objective of the invention is to overcome above-mentioned weak point of the prior art, and provide a kind of novel ceramic powder pelletizing apparatus and production technology, its device structure advantages of simple, low cost, technological process is simple, and is with short production cycle, save the energy and water, granulating quality height.
The object of the present invention is achieved like this: the equipment that is adopted comprises that Hubei Province breaks machine, high pressure overhang roll mill, bucket elevator, hopper, granulation towter, conveying worm, drying machine, vibratory sieve, belt conveyor, storage bin, its granulation towter is a cylindricality garden tube, the junction of it and hopper is equipped with air blast, the top is equipped with powder atomizing blade, lower central is equipped with water atomizing nozzle, and the bottom is equipped with the rotating granulation dish; The center is equipped with a pair of intermeshing bevel gear below the rotating granulation dish, and one of two angular wheel shaft are vertically fixedlyed connected with the rotating granulation dish, and a level decelerator main shaft outer with being installed in granulation towter is connected; The lower end of granulation towter is connected with into the whole grain tube of taper, and the lower end of whole grain tube is connected with conveying worm.
Production technology of the present invention, comprise and get material, coarse crushing, in small, broken bits, batching, granulating, oven dry, storing, its granulating process is: when powder falls into granulation towter from hopper, produce the normal temperature pressure wind by air blast, powder is exerted pressure, through rotation at a high speed behind the powder atomizing blade, nebulize and enter granulation towter, when vaporific powder falls in granulation towter, with the atomized water reverse movement that upwards sprays by water atomizing nozzle, evenly mix, form solid particulate and fall within on the rotating granulation dish, the rotating granulation disc spins, powder to the border movement shaping, falls into whole grain tube along the garden czermak space under centrifugal action, be delivered to drying machine drying by conveying worm, sieve again, and it is standby to be delivered to storage bin.
Compared with prior art, the invention has the advantages that:
1, device structure advantages of simple, volume is little, and is in light weight, and reduced some auxiliary equipment, so the equipment investment minimizing, reduced energy resource consumption, and comprehensive cost only is 20% of a prior art.
2, simplify technological process, shortened the production cycle, reduced production cost.
3, granulating is even, good fluidity, and the quality height is applicable to handpress and automatic hydraulic press production requirement fully.
The explanation of accompanying drawing drawing:
Accompanying drawing is equipment flowsheet of the present invention and granulation towter structural representation.
Below in conjunction with drawings and Examples in detail the present invention is described in detail.
Equipment required for the present invention, comprise that jaw breaks machine (18), high pressure overhang roll mill (19), bucket type is carried machine (20), hopper (1), granulation towter (21), conveying worm (12), drying machine (13), vibratory sieve (14), belt conveyor (15), bucket elevator (16), storage bin (17), its characteristics are: granulation towter (21) is a cylindricality garden tube, the junction of it and hopper (1) is equipped with air blast (2), the top is equipped with powder atomizing blade (3), lower central is equipped with water atomizing nozzle (4), and the bottom is equipped with rotating granulation dish (22); The center is equipped with a pair of intermeshing bevel gear (5) (6) below the rotating granulation dish, and (7) one of two angular wheel shafts are vertically fixedlyed connected with rotating granulation dish (22), and level decelerator (a 8) main shaft outer with being installed in granulation towter (21) is connected; The lower end of granulation towter (21) is connected with into the whole grain tube (11) of taper, and the lower end of whole grain tube (11) is connected with conveying worm (12).Powder atomizing blade (3) is 6-8 sheet garden Zhou Junbu, and it is shaped as arc, and 100 millimeters of garden arc radiuses are 45 ° along the angle of inclination of axis.Rotating granulation dish (22) is the garden dish type, leaves garden czermak space (9) between it and granulation towter (21) inwall, and border line speed is 3-5m/ second during work.
