Description
(1) technical field
The utility model relates to casting industry and is used to prepare the puddle mixer of moulding with sand.Its function is that the sand grains of certain proportioning, clay, moisture and other additives are mixed, and fully crumple, mixed grind, make sand grain surface evenly coat one deck clay mambrane, become available molding sand.
(2) background technology
At present, being used to prepare the puddle mixer of moulding with sand at casting industry, mainly is rotator mixed sand machine.This rotator mixed sand machine is made of the cylindrical shell on chassis, the chassis and the rotor in the cylindrical shell and scraper plate, and scraper plate wherein is under the rotor.During work, chassis and cylindrical shell maintain static, rely on scraper plate stir carry out a cut-off sand to rotor, realize sand grains, clay, moisture and other accrete even mixing with this.Though adopt this puddle mixer, can realize sand grains, clay, moisture and other accrete even mixing, because its chassis and cylindrical shell maintain static, have only stirring to carry out a cut-off sand to rotor by scraper plate, mulling efficient is not high.Because scraper plate is under the rotor and occupies certain height and the space, make rotor stretch again, also can reduce mulling efficient less than the cylindrical shell bottom.In addition, because Dump gate is opened on the sidewall of cylindrical shell, the discharge time is long, and efficient is not high.Again on the one hand, this puddle mixer is except that rotor consumes certain power, and its main power consumption is on scraper plate, and energy consumption is bigger, and production cost is higher.
(3) summary of the invention
The purpose of this utility model is to provide a kind of puddle mixer.This puddle mixer, mulling efficient height, less energy consumption, production cost are low.
Above-mentioned purpose of the present utility model is realized by following technical solution:
Puddle mixer of the present utility model comprises frame, and cylindrical shell is arranged on the frame, and Dump gate is arranged on the cylindrical shell.The bearing block and the bearing thereof that make the cylindrical shell rotation are arranged between frame and cylindrical shell chassis.Cover plate is arranged at cylindrical shell top, and this cover plate is fixed on the top of frame.Axis hole is arranged on the cover plate, main shaft is arranged in the axis hole.There is rotor the main shaft lower end, and there is big belt wheel its upper end.On the frame of cylindrical shell one side motor is arranged, on the output shaft of this motor small pulley is arranged.Is furnished with driving-belt between said large and small belt wheel.Its design feature is on the frame in the cylindrical shell outside drive motors to be arranged, and is useful on the output shaft of this drive motors and drives the drive that cylindrical shell rotates.
Adopt such scheme, have the following advantages:
Owing on cylindrical shell one side frame of the utility model puddle mixer drive motors is arranged, be useful on the output shaft of this drive motors and drive the drive that cylindrical shell rotates, relying on drive to drive cylindrical shell rotates, the rotor continuous feeding that material in the cylindrical shell is stirred clockwise and be rotated counterclockwise to high speed, form the logistics of high speed reverse flow, can produce strong rubbing effect between the logistics of these two strands high-speed poor mutual reverse movements, make sand grain surface coat one deck clay thin film equably.Thereby improved mulling efficient greatly.
Because cylindrical shell rotates, saved tube sheet again, made the rotor lower end can reach the cylindrical shell bottom, the length of effectively utilizing of rotor increases, and also can improve mulling efficient.
In addition, owing to saved scraper plate, reduced energy consumption.Energy consumption one is low, and production cost is just low.Therefore, can reduce production costs.
Again on the one hand, because Dump gate is opened on the cylindrical shell chassis, discharge rate is fast, can increase work efficiency.
(4) description of drawings
