Abstract

The utility model relates to a novel disc type granulation machine, belonging to a granulation device of powdery materials, especially suitable for the granulation process of complex fertilizer. The rate of balling of an existing disc type granulation machine with a flat bottom or an existing granulation machine with a ladder-shaped bottom is low, oversize balls are frequently generated, and a disc type granulation machine with an ellipsoid bottom can not be spread because processing is difficult. The utility model is a novel disc type granulation machine using an approximate ellipsoid face which is composed of a center plane and the side faces of two to three round platforms as a disc bottom, and can be provided with a wheel flange chamber which uses the side faces of the round platforms as a bottom. The utility model not only can quickly enable a majority of powdery materials to be changed into sphere-shaped particles of needed size, even particle and smooth surface, and the utility model has the advantages of easy production and low cost.

Description

Novel disc type comminutor

The utility model belongs to by spraying into water (or steam) and certain liquid granular material is manufactured the device of particle, can be used for the various occasions that will cause granular material particle, is specially adapted to the granulation process of complex fertilizer.

The inclination that the disc type comminutor drives by frame, power set, central shaft and by central shaft; can form around the disk that central shaft rotates; usually also with liquid sprayer, the adjusting device at card angle of inclination, the scraper of cleaning disk bottom surface and discharger that can lifting.The rotating circular disk of the disc type comminutor that generally uses in the factory is the disk of the flat of belt edge barricade or stairstepping bottom surface now.The movement velocity of this class disc type comminutor material in dish is inhomogeneous and can produce big particle in the accumulation of knuckle place, disk bottom surface, so it can not cause the overwhelming majority of granular material the particle of the size that requires.The fifties German has invented a kind of disc type comminutor (Germany patent; No. 971284, specification); the rotating circular disk of this disc type comminutor is for having the edge barricade; the bottom surface becomes the disk of slight ellipsoid; and one and the common rotation of disk are housed in the edge barricade outside, cross sectional shape is the semi-circular marginal cell of taking turns of specific curves.This disc type comminutor has good granulation performance, but the bottom surface of disk and wheel marginal cell all can not the generate plane.Therefore its makes difficulty, processing cost is high, to having limited promoting the use of of it.

The purpose of this utility model is that a kind of granulation performance of invention is good, is convenient to manufacturing, with low cost.The novel disc type comminutor that is easy to promote.

This novel disc type comminutor; the middle body that rotating circular disk is tried to get to the heart of a matter is a circular flat; the inward flange of the outer ring portion of trying to get to the heart of a matter that the edge of circular flat and 2-3 the intilted frustum cone side that the order of successively decreasing by cone angle from the inside to the outside welds together outer edge are successively formed welds mutually, and the outward flange of the outermost frustum cone side of trying to get to the heart of a matter is welded with an edge barricade.What the outside of novel disc type comminutor disk border barricade can be provided with the common rotation of and disk is the semi-circular marginal cell of taking turns at the end with intilted frustum cone side, and the outermost edge at the bottom of the wheel marginal cell is welded with a wheel marginal cell barricade.Inward flange at the bottom of the wheel marginal cell frustum cone side shape can directly be welded on the edge barricade of disk, also can be at the bottom of wheel marginal cell frustum cone side shape with weld a planar circular intermediate zone between the disk border barricade or weld a hoop that to cut the part of annulus open be the corner intermediate zone, promptly the inward flange at the bottom of the wheel marginal cell frustum cone side shape is welded mutually with the outward flange of intermediate zone, the edge barricade of the inward flange of intermediate zone and disk is welded mutually.This novel disc type comminutor also can have liquid sprayer, the adjusting device at card angle of inclination, cleaning disk and the scraper of wheel bottom surface, marginal cell and discharger that can lifting.

The rotating circular disk of this novel disc type comminutor and wheel marginal cell can be launched into the plane, can directly roll with sheet material.Therefore it is easy to manufacture (almost any machining factory can make), with low cost.This novel disc type comminutor, the movement velocity of material in dish is even, and material can not pile up at the edge of disk, so it most granular materials can be manufactured require size, epigranular, ganoid spheric granules.When the outside of rotating circular disk is provided with the wheel marginal cell, can improve the production capacity and the balling-up efficient of comminutor, and can make the particle densification of generation, can also apply the surface of causing particle with granular material simultaneously.This novel disc type comminutor has removed the redundance that is easy to pile up material in the disc type comminutor disk that generally uses in the present factory; improved the movement velocity of material in disk; improved the production capacity of comminutor; simultaneously also significantly reduce the loadings of material in the disk, thereby reduced the power consumption of comminutor.Therefore it has remarkable energy saving effect, is a kind of high-efficiency and energy-saving type comminutor.

Accompanying drawing is that central plane and two frustum cone sides are formed the disk bottom surfaces and had the novel disc type comminutor disk of taking turns the marginal cell and the profile of wheel rim chamber internal surface.The first half among the figure is the situation of wheel bottom surface, marginal cell when being provided with a planar circular intermediate zone, and the latter half is the situation when being provided with the corner intermediate zone.As shown in the figure; the center of the central shaft (1) that novel disc type comminutor is tilting and the central, circular planar section (3) of trying to get to the heart of a matter of rotating circular disk (2) is connected; try to get to the heart of a matter middle body (3) the edge and slope inwardly; the frustum cone side that cone angle successively decreases (4); (5) welding successively; and by (3); (4); (5) form the end of rotating circular disk (2) jointly; the edge barricade (6) of the outward flange welding rotating circular disk of frustum cone side (5); the outside of the edge barricade (6) of rotating circular disk (2) is provided with a wheel marginal cell (7); the inward flange at the end (8) of the intilted frustum cone side shape in wheel marginal cell is welded on the outward flange of planar circular intermediate zone (9) or corner intermediate zone (10); the inward flange of planar circular intermediate zone (9) or corner intermediate zone (10) is welded on the disk border barricade (6), the outward flange weld wheel marginal cell barricade (11) at the end (8) of wheel marginal cell frustum cone side shape.

Novel disc type comminutor shown in the drawings; by tilting central shaft (1) driven rotary disk (2) and wheel marginal cell (7) rotation; can will add the granular material in the disk (2) continuously; cause the single-size of desirable amount continuously, expeditiously, the particle of the making lower edge of trailing wheel marginal cell barricade (11) continuously throws away (or keep off with liftable discharger).Facts have proved the production that novel disc type comminutor shown in the drawings is used for complex fertilizer, can with various powdered fertilizer mixtures cause more than 95% 2～4.75 millimeters, epigranular, smooth surface, in conjunction with fine and close spheric granules.
