Description

Clay sand mixing machine

Technical field

This utility model relates to a kind of clay sand mixing machine.

Background technology

The clay sand mixing machine that casting uses at present mainly includes simpson mill and rotator mixed sand machine two class.

Wherein, simpson mill is blended molding sand and core sand for foundry, motor by elastic dowel pin shaft coupling with The power shaft connection of decelerator, through three grades of decelerations, is then driven crosshead to do counter clockwise rotation by the output shaft of decelerator.Tightly Gu cranking arm in crosshead, muller, inside and outside scraper plate are followed crosshead and are together turned round.Simpson mill is generally equipped with two stone rollers Wheel and two scraper plates, wherein, muller has the effect rolling and rubbing, and makes moisture, clay and other additament be evenly distributed on sand Grain surface, scraper plate makes sand lump loose, and makes the sand not mixed scrape on muller, continues to roll and rub, until all mixing out Sand.Existing rotator mixed sand machine is disc type puddle mixer, including chassis rotary type and chassis not dynamic formula two kinds.The most often Be chassis not dynamic formula puddle mixer, it includes rotor mechanism, rotating blade mechanism, body, top cover and chassis；Rotor mechanism Extending downwardly from two power transmission shafts from top cover, two power transmission shafts are the most concentric with chassis, and the lower end of power transmission shaft is provided with high speed rotor, Its range of speeds is 200～2000r/min, can enter by the granularity of material, hardness and grain shape according to the purposes of puddle mixer Row selects；Rotating blade mechanism is by the motor of organism bottom, belt pulley, reductor, shaft coupling and the biography passed bottom-up Moving axis form, power transmission shaft is provided with four pieces of blend tools being made up of the scraper plate of differing heights and different angle, be used for digging and Mixing material, its rotating speed is 24～40r/min.The chassis of chassis rotary type puddle mixer and enclosure rotate, and rotating speed is 6～8r/min, The rotor mechanism of the rotor mechanism of chassis rotary type puddle mixer and chassis not dynamic formula puddle mixer is essentially identical.

Above-mentioned two class puddle mixers of the prior art are batch (-type) puddle mixer, and substantially work process is for disposably to add in mixing chamber Enter the raw materials such as sand, clay and coal dust, under the effect of scraper plate and rotor or muller, add water after stirring and stir, wherein, The each work process of simpson mill continues 3～8 minutes, and each work process of rotator mixed sand machine continues 2～5 minutes.By It is batch (-type) puddle mixer in above-mentioned two class puddle mixers, thus continuous prodution cannot be realized.Additionally, simpson mill is mixed Type is often caused to move " cake of press " phenomenon during sand.Rotator mixed sand machine is not owing to having muller, and scraper plate and rotor are typically embedded in Working in layer of sand, therefore the layer of sand height on puddle mixer chassis can increase, and one time feeding quantity is also many than simpson mill, just It is owing to the layer of sand on rotator mixed sand machine chassis is thick, has accordingly increased power consumption.
