Technical field

The utility model relates to a kind of molding sand production equipment, promptly a kind of molding sand swaging machine.

Background technology

Molding sand is a kind of important raw material of industry, in casting technique, has specific use.At present, the molding sand of China is mainly produced through washing process by natural silica Sand.Past because some impurity that are difficult to remove of surface attachment of natural silica Sand particle will be removed impurity and produce clean molding sand, needs to adopt alkaline soak, and cost is very high, and waste water is difficult to handle, and exhaust emission is serious.Nineteen eighty-three, the big crop type sand of Tongliao, Inner Mongolia factory takes the lead in adopting mechanical scrub technology, has produced clean scouring sand, makes the molding sand production technology that breakthrough progress take place., along with the raising of China's process industry level, the quality and the cost of molding sand all proposed new requirement, the production efficiency of existing friction scrubbing apparatus also needs to improve with the clean level of product, and power consumption and integrated cost also need further reduction.

Summary of the invention

It is high that the purpose of the utility model provides a kind of production efficiency, good product quality, energy-saving and cost-reducing molding sand swaging machine.

Above-mentioned purpose is realized by following technical scheme: develop a kind of molding sand swaging machine, be characterized in: the main body of this swaging machine is columniform tank body, and tank body is provided with sand inlet and sand export; The fixed blade that multi-disc is erect is housed on the inner tank wall; The main shaft of setting is equipped with in the centre of tank body, and moving vane is housed around the main shaft, and tank body is stretched out in the main shaft upper end; On the loam cake of tank body, motor is housed, the power output wheel of motor interrelates through the drive of drive disk assembly and main shaft upper end.

Said sand inlet and sand export are located at the tank body both sides respectively, and stagger up and down.

Said moving vane has two groups up and down at least, and every group is uniformly distributed with 3-5 moving vane, and the relative main-shaft axis of the face of each blade all has an inclination angle, and neighbouring two groups moving vane incline direction is opposite.

The angle of inclination of said moving vane is 35-40 °.

Said tank body has and carries out tandem compound more than two, main shaft and moving vane that each tank body the inside all has a cover to be driven by the engine of tank body outside, and the sand export of a tank body is connected with the sand inlet of adjacent tank body.

The beneficial effect of the utility model is: the sand material is thrown up and down in tank body and is sent; Scrub fully, can remove the pollutant that the sand grains outer surface adheres to, production efficiency significantly improves; Power consumption and integrated cost obviously reduce; The work in tandem of a plurality of tank bodies particularly, the cleanliness factor of molding sand significantly improves, and can adapt to the demand of high level casting technique.

Fig. 2 is the vertical view of first kind of embodiment;

Fig. 3 is the A-A sectional drawing of first kind of embodiment;

Fig. 4 is the front view of second kind of embodiment.

Visible among the figure: tank body 1, sand inlet 2, fixed blade 3, main shaft 4, moving vane 5, cover 6, motor 7, power output wheel 8, drive 9, installing rack 10, shaft coupling 11, sand export 12.

The specific embodiment

The total design of the utility model is: the sand material that will get into tank body through the moving vane that tilts is thrown at a high speed and is seen off; And the flight path through fixed blade blocking-up sand material; The brute force that the sand material is received is repeatedly impacted, thereby minimum in power consumption, under the minimum condition of operating cost; The sand material that gets into tank body is washed fully, and the attachment of sand grain surface is removed completely.Introduce two kinds of embodiment below in conjunction with accompanying drawing.

First kind of embodiment: like Fig. 1, shown in 2, the main body of this molding sand swaging machine is columniform tank body (1), and a side of tank body (1) is provided with sand inlet (2), and opposite side is provided with sand export (12), and the fixed blade (3) that multi-disc is erect is housed on the inner tank wall.The main shaft (4) of setting is equipped with in the centre of tank body, and two groups of moving vanes (5) up and down are housed on the main shaft (4) at least, and what represent among the figure is three groups of moving vanes (5).Every group of moving vane (5) is 3-5 moving vane (5), and what recommend among the figure is four.The relative main shaft of face (4) axis of each moving vane (5) all has an inclination angle, and the angle of inclination is 35-40 ° is advisable, and requires neighbouring two groups moving vane (5) incline direction opposite.Tank body (1) is stretched out in main shaft (4) upper end, on the loam cake (6) of tank body (1), installing rack (10) is housed, and motor (7) is housed above the installing rack (10), and the power output wheel (8) of motor (7) is formed transmission through the drive (9) of driving-belt and main shaft (4) upper end.Reliable for stable drive, main shaft (4) epimere is provided with a shaft coupling (11).Visible by figure, sand inlet (2) and sand export (12) are located at the both sides of tank body (1) respectively, and one one is being descended last, staggering up and down helps the sufficient movement of sand material.

During work, moisture content is that the mortar of 30-40% gets into tank body (1) through sand inlet (2), is between two groups of moving vanes (5); Two groups of incline directions are opposite up and down owing to moving vane (5), and it is big to form an import, goes out young network interface; Make the sand material receive increasing extruding and friction, and by one deck moving vane (5) with turning on the sand material, another layer moving vane (5) presses down it; Cause fast repeatedly; Each in addition throwing send route to be blocked by the fixed blade (3) on tank body (1) inwall again, has aggravated the impact of material movement, and the attachment of sand grain surface is separated by brute force.

Second kind of embodiment: as shown in Figure 3; Be together in series a plurality of tank bodies (1); Recommend three tank bodies (1) series connection among the figure, all there are axis (4), moving vane (5) and fixed blade (3) in each tank body the inside, and the sand export (2) of a tank body (1) is connected with the sand inlet (12) of adjacent tank body (1).The sand material can be cleaned through three times continuously, and clean level is higher.According to experiment showed, the sand material by entering out scouring 4-7 minute, clay content can drop to 0.2-0.3% from 0.8-1%, has reached the top standard of domestic similar technology.
