Abstract
The utility model discloses a sand screening device, which comprises a support, a roller and a motor. The motor and a feeding chute are installed on two sides of one end of the support respectively, a driving wheel is installed at the end of an output shaft of the motor, and the roller is obliquely installed on one side of the support where the motor is located. One end of the roller serves as a feeding port, the other end of the roller serves as a discharging port, and the feeding port is larger than the discharging port. The roller is formed by steel wires which are woven into a mesh shape, a revolving shaft penetrates through the roller and is integrally fixed on the inner wall of the roller through a support rod, a driven wheel is fixed at one end of the revolving shaft, and a belt is arranged between the driven wheel and the driving wheel in a sleeved mode. The sand screening device is simple in structure and adopts the roller which is formed by steel wires which are woven into the mesh shape and is obliquely installed in a rotary mode. The feeding port of the roller is larger than the discharging port of the rotary drum, and molding sand enters into the rotating roller from the feeding chute to be screened, thereby effectively improving screening quality of the molding sand, simultaneously saving a large amount of time and improving production efficiency.
Description
Technical field:
The utility model relates to the casting manufacture field, relates in particular to a kind of sand sifter.
Background technology:
Molding sand is to be used for the material of moulding in sand casting.Molding sand generally mixes also available natural silica sand argillaceous according to a certain percentage by casting model powder, moulding sand binder and the auxilliary Modeling Material such as thing that adds.The effect of molding sand in Foundry Production is very important, and the casting wasted product that causes because of the poor quality of molding sand accounts for 30～50% of the total waste product of foundry goods.Usually the requirement to molding sand is: 1. have higher intensity and heat endurance, to bear various external force and action of high temperature.2. good flowability, promptly molding sand is in the ability that moves mutually between sand grains under external force or the gravity effect own.3. certain plasticity, promptly molding sand is out of shape under external force, can keep the ability of the shape that given after external force is removed.4. gas permeability preferably, promptly the molding sand hole sees through the ability of gas.5. high collapsibility weighs up grittiness again, and promptly whether molding sand destroys easily behind casting solidification, the performance of whether removing from foundry goods easily.Molding sand can be divided into clay-bonded sand, water-glass sand, cement bonded sand, resin sand etc. by used binding agent difference.With clay-bonded sand, water-glass sand and resin sand use at most.
At the molding sand in the casting process of wear-resisting ball, casting these molding sand of good back at wear-resisting ball needs to recycle once more to cast, and can effectively save cost, before all has been to utilize manually to sieve sand, inefficiency, and the granularity of screening is even inadequately.The utility model project organization is simple, and is economic and practical, can effectively address the above problem.
The utility model content:
In order to solve the prior art problem, the purpose of this utility model provides a kind of sand sifter, effectively raises the efficient of screening molding sand, and Shai Fen quality increases simultaneously.
The technical solution of the utility model is as follows:
Sand sifter, comprise support, cylinder, motor, it is characterized in that: described support one end both sides are separately installed with motor, feed well, described motor output shaft end is equipped with driving wheel, described support is positioned at the motor lopsidedness cylinder is installed, described cylinder one end is a charging aperture, the other end is a discharging opening, described charging aperture is greater than discharging opening, described cylinder is that braided steel wire reticulates formation, has rotating shaft to pass cylinder, and rotating shaft is integral in inner wall of rotary drum by strut fixation, described rotating shaft one end is fixed with driven pulley, and cover thongs between described driven pulley and the driving wheel.
Described sand sifter is characterized in that: described support lower end is equipped with roller.
Described sand sifter is characterized in that: described feed well notch extend in the charging aperture.
The utility model has the advantages that:
Of the present utility model simple in structure, adopt the inclination of braided steel wire formation, the cylinder that rotation is installed, the cylinder charging aperture is greater than discharging opening, molding sand sieves sand work from the cylinder that feed well enters into rotation, improved the screening quality of molding sand effectively, save a large amount of time simultaneously, thereby improved production efficiency.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Sand sifter, comprise support 1, cylinder 2, motor 3, support 1 one end both sides are separately installed with motor 3, feed well 4, motor 3 output shaft ends are equipped with driving wheel 5, support 1 is positioned at motor 3 lopsidedness cylinder 2 is installed, cylinder 2 one ends are charging aperture 6, the other end is a discharging opening 7, and charging aperture 6 radiuses are greater than discharging opening 7, and cylinder 2 reticulates formation for braided steel wire, there is rotating shaft 8 to pass cylinder 2, rotating shaft 8 is fixed in inner wall of rotary drum by pole 9 and is integral, and rotating shaft 8 one ends are fixed with driven pulley 10, and cover thongs 11 between driven pulley 10 and the driving wheel 5, support 1 lower end is equipped with roller 12, and feed well 4 notches extend in the charging aperture 6.
Claims (3)
1. sand sifter, comprise support, cylinder, motor, it is characterized in that: described support one end both sides are separately installed with motor, the feed well that tilts, described motor output shaft end is equipped with driving wheel, described support is positioned at the motor lopsidedness cylinder is installed, described cylinder one end is a charging aperture, the other end is a discharging opening, described charging aperture is greater than discharging opening, described cylinder is that braided steel wire reticulates formation, has rotating shaft to pass cylinder, and rotating shaft is integral in inner wall of rotary drum by strut fixation, described rotating shaft one end is fixed with driven pulley, and cover thongs between described driven pulley and the driving wheel.
