Abstract
The utility model discloses a novel rotor sand mixer which adopts a composite structure of a center rotary scraper and rotors arranged aside, makes use of the theory of bonded low and middle speeds, and makes molding sand impacted, shorn, rubbed and mixed. The utility model has the advantages of simple structure, light weight, low cost, high efficiency of sand mixing, low energy consumption, adequate quality of the sand mixing, productivity twice of a domestically advanced high efficiency running wheel sand mixer, green compression strength and ventilation property, both better than other sand mixers.
Description
The utility model is about the novel rotor puddle mixer in the casting model powder processing machine.
Before the utility model, have the powerful reverse-flow puddle mixer of West Germany Eirich company development abroad; The WM type rotator mixed sand machine of KW company development; The STM type turbine type puddle mixer of Switzerland GF company development; The CM type puddle mixer of West Germany BMD company development; The adverse current rotator mixer that domestic existing State Patent Office announced in January, 1986 etc.Above-mentioned all kinds of rotator mixer is concluded and is got up can be divided into high speed impact type and stirring at low speed type.High speed impact type rotator mixer generally has the rotor of 1 to 2 high speed rotating, and its rotating speed is at 500～1000 rev/mins.Owing to the rotor speed height, limited the operating radius of rotor, and power consumption is big, and should causes the molding sand heating up, the green compression strength of mixing the system molding sand is lower than muller, thereby the puddle mixer narrow application range of this class type.The puddle mixer of stirring at low speed type, as the CM puddle mixer have interior, in, outer three groups of scraper plates, rotate around center chassis by rightabout each other.Because rotating speed low (having only 13～24 rev/mins), energy consumption is also low.But it is poor to impact, the fragmentation of clay group in the mulling process.And the scraper plate that this machine is turned to by three layers of difference of a cover actuator drives, complex structure, manufacturing cost height.
The purpose of this utility model is to provide the novel rotor puddle mixer of a kind of low speed center rotor segment and middling speed side rotor combining structure, to solve the deficiency of above-mentioned all kinds of types, reaches and improves mulling ability and quality, cut down the consumption of energy, simple in structure, reduce manufacturing cost, purpose easy to maintenance.
Below in conjunction with description of drawings embodiment of the present utility model:
The utility model is made of two side rotor mechanisms of novel rotor puddle mixer motor (11), transmission device (16), rotor (12), blade (2); By scrape panel seat (15), quicksand awl (14), scraper plate (9), (10) wait organization center rotor segment assemblies, and drive by motor (7), shaft coupling (4), decelerator (5) and to turn round; Enclosure (1), chassis (3), cast stone lining and cast stone (8), supporting leg (6) are formed the main part of machine.
The detailed connection and the special construction of each part mentioned above are as follows:
Motor (11) is fixed on the outer circumferential surface of enclosure (1), and two rotors (12) are placed with the axial line symmetry, and rotor (12) makes its rotation by transmission device.2 to 4 layers of blade (2) are fixed in the bottom of rotor (12), blade and horizontal plane angle 15 to 60 degree; Enclosure (1) is fastened on the circumference of chassis (3), and chassis (3) are fixed on 4 supporting legs (6).Pave cast stone lining and cast stone (8) above the chassis (3), below fixed motor (7), drive center scraper assembly (13) rotation through shaft coupling (4), reduction box (5).Scrape panel seat (15) for cylindrical, column top is equipped with quicksand awl (14).Scrape fixedly scraper plate (9) of panel seat (15) bottom, and make it be close to upward plane of cast stone lining and cast stone (8).Scraper plate (9) tactical diameter is approximately equal to enclosure (1) internal diameter.Scrape panel seat (15) axially in the external cylindrical surface, top, fix 1 to 2 layer of scraper plate (10).Scraper plate (9), (10) radially are flat straight type or shaped form, with horizontal sextant angle be 15 to 45 the degree.During assembling, the clearance control that should make scraper plate (9), (10) and blade (2) is at 10 to 50 millimeters.
The utility model, side rotor (12) rotating speed is 100～400 rev/mins; Center rotor segment assembly (13) rotating speed is 15～55 rev/mins; Turning to of side rotor (12) can be clockwise, also can be counterclockwise.
The disk track that the utility model is implemented is 1000 millimeters.Two group rotors (12); Two layers of blade of every group rotor (2); Blade (2) and horizontal sextant angle 15 degree; Two-layer scraper plate (9), (10) and horizontal sextant angle 30 degree; Center rotor segment assembly (13) rotating speed is 45 rev/mins, and rotor speed is 300 rev/mins.Blade (2) and 20 millimeters in scraper plate (9), (10) gap.This embodiment be University Of Tianjin on the rotator mixer testing stand of 400 millimeters of disk tracks, the intermediate experiment of after the experimental study more than 2 years, carrying out.After measured, the productivity ratio of this embodiment is domestic advanced person's two times of the efficient muller of same disk track, also is higher than all kinds of rotator mixers with disk track; Performance indications such as the green compression strength of mixed system molding sand, gas permeability all are better than other puddle mixer; Need not any protective device and get final product load starting; Machine construction is simple, and is in light weight, and complete machine weight only is 1/2nd (energy loss-rate muller saves 1/3rd) of the efficient puddle mixer of identical ability to work with manufacturing cost.
The utility model can require to be designed to the series of products of plurality of specifications according to difference, to satisfy the development need of China's casting industry.
Claims (2)
1, a kind ofly be used for the novel rotor puddle mixer that casting model powder is handled, it is characterized in that having (12) 1 to 2 groups of side rotors, every 2 to 4 blades of group rotor axial restraint (2), and with horizontal sextant angle be 15 to 60 degree; Center rotor segment assembly (13); Cylindrical scrape panel seat (15) lower curtate fixedly tactical diameter to be approximately equal to enclosure (1) internal diameter be flat straight shape or curved scraper plate (9), in, top fixes 1 to 2 layer and is flat straight shape or curved scraper plate (10), top is the quicksand awl (14) of quicksand shape.
2, according to the said novel rotor puddle mixer of claim (1), it is characterized in that described blade (2), the spacing between scraper plate (9), (10) is 10 to 50 millimeters.
