Description
Technical field
The present invention relates to the abrasive material number of changing equipment, a kind of abrasive material F sand shaping number of changing machine specifically, to pass through abrasive action, by sheet, the irregular sand particle size such as pointed, be shaped as spherical, increased the wearability of sand grains, make sand grains change model, then collect and classification through collection equipment, thereby obtain the sand mold of expecting.
Background technology
Grinding materials and grinding tool, as " tooth " of industry, is widely used in a plurality of industries such as device fabrication, machining, iron and steel, electrician, building.Grinding materials and grinding tool industry especially with the development close relation of mechanical industry, steel and iron industry, there is unique importance in national economy.China manufactures big country as grinding materials and grinding tool, and its output and export volume are all at the forefront in the world.And be ascendant trend year by year.Because technological process determines, can produce a large amount of dust and pernicious gas in grinding materials and grinding tool manufacturing process, pollute very serious.Although most of manufacturing enterprise has taked some effective dust-proof dust-removing measures, improve to a certain extent production environment, improved product quality, safeguarded workman's physical and mental health, but because of various reasons, remain in some problems and fail to be solved at all.Along with the raising day by day of national requirements for environmental protection and the foundation of IS01400 system, these problems are further outstanding, arrive the restriction grinding materials and grinding tool and manufactured the stage of industry development, must seek to conform with the countermeasure of China's national situation, farthest improved the environmental aspect that grinding materials and grinding tool is manufactured enterprise.
The product of China's grinding materials and grinding tool industry does not adapt to the demand in market fully.Once some abrasive products occur superfluous, the equipment of the shaping number of the changing aspect of China is again in blank, can not the shaping number of changing between different abrasive sand models, the abrasive material resource just can not obtain sustainable use, not only may cause certain inconvenience even to lose to enterprise, the superfluous abrasive material of shelving be also a kind of waste to social resources.
Summary of the invention
Purpose of the present invention just is being based on above-mentioned prior art situation, for filling up blank of carrying out the shaping number of changing of the prior art, and provide a kind of abrasive material F sand shaping number of changing machine, this device structure is scientific and reasonable, production efficiency is high, technical performance is stable, and Operation and Maintenance is simple, safe and reliable to operation, can will occur that the superfluous low and middle-grade abrasive material shaping numbers of changing become high-end product salable, a kind of new technology, new technology that can represent domestic shaping device developing direction of can yet be regarded as by the present invention.
The objective of the invention is to realize by following measures:
A kind of abrasive material F sand shaping number of changing machine, comprise vertical casing cylinder, be vertically set on central shaft in the housing inner chamber, around the housing cavity arrangements and sit the bull ring that is placed on the circular air inlet dish on cylinder bottom plate and is flush-mounted in the circular air inlet dish first half, circular air inlet dish Lower Half is evenly equipped with oblique tooth-like air inlet duct, the plum blossom frame is arranged on the central shaft upper end, on the plum blossom frame, be lifted with three can rotation grinding roller, grinding roller is driven to move in a circle by central shaft by the plum blossom frame and coordinates abrasive particle is ground with bull ring; Be set with and be fixed with a disc type screen being positioned on the lower central axle of cylinder lumen, the screen diameter is greater than the bull ring internal diameter, is less than the bull ring external diameter, and screen is positioned at the grinding roller below apart from grinding roller lower surface 2-5cm, is evenly equipped with airflow hole on screen; The central shaft lower end is stretched out cylinder bottom plate and is connected with drive motors by transmission mechanism; Circular air inlet dish periphery is surrounded with the circular air inlet chamber communicated with each oblique tooth-like air inlet duct; The cylindrical shell middle part is provided with feed opening, and discharging opening is arranged on the top of cylindrical shell.
In invention, described disc type screen is combined by three blocks of fan-shaped screens, with grinding roller quantity, is complementary; On described screen, uniform its vertical section of airflow hole is lower large little convex structure, and pitch of holes is 12-18mm.Bore dia 4-6mm on the airflow hole of convex structure, lower Kong Zhijing 8-12mm, the air-flow sky of this shape more easily produces high-pressure blast, can meet the grains of sand by the needs of having taken away with air-flow air inducing after having eaten.
Each fan-shaped screen centre is provided with three fixing holes, and fan-shaped screen is connected and fixed by this fixing hole and grid support pawl and central shaft.
Drive motors, by Frequency Converter Control, can be realized the discharging-material size of F sand and freely controlling of output.
Operation principle of the present invention is: abrasive material falls within main frame on screen via charging aperture; blower fan blows into the wind come and enters under the screen in main frame through circular air inlet dish, oblique tooth-like air inlet duct; upwards form air blast; the sand grains that will be shelved on screen by airflow hole has blowed floating; the sand grains that does not meet model in presumptive area can be due to from great and can't directly be taken away by air inducing; the sand grains landing is to the abrasive areas of grinding roller and bull ring; through abrasive action; sand grains is taken away by air inducing from discharging opening after being milled to predetermined sand mold, thereby reaches the purpose of the sand mold number of changing.
The sand of being taken away by air inducing is further collected and classification via the two stage cyclone separator again, waste gas reenters the circular air inlet chamber of the number of changing machine after by the deduster filtration treatment, can repeat to be utilized by blower fan, so just formed the interior circulation F sand processing air flow system that only has a Fans, whole process is that environmental protection is efficient again.
The invention has the advantages that:
(1) can make F8#-F20# sand into F30#-F36#-F40# sand by this equipment, adjust product type.
(2) the host center axle is connected with drive motors, the drive motors rotating speed is by Frequency Converter Control, the rotating speed of regulating central shaft can change discharging-material size and the output of F sand, therefore the drive motors under Frequency Converter Control, regulated the rotating speed of host center axle, can realize the discharging-material size of F sand and freely controlling of output.
(3) utilize air blast and screen to make abrasive material become suspension, more be conducive to the separation of different abrasive material sand molds.
(4) this equipment utilization one Fans forms the F sand processing air flow system of interior circulation, the high and environmentally safe of efficiency simple to operate.
