Abstract
The utility model discloses a screening device for casting moulding sand. The screening device comprises a screen drum arranged on a support in an inclining manner, wherein one end of the screen drum is a feeding port, and the other end of the screen drum is a discharging port of impurities; a discharging port end is lower than a feeding port end, a support of one side of the feeding port is provided with a motor, and the motor is in transmission connection with the end part of a revolving shaft in the screen drum through a belt; and the support arranged above the screen drum is provided with a rolling shaft in a rotating manner, flexible belts are distributed on the outer wall of the rolling shaft at intervals, the flexible belts arranged on the lower part of the rolling shaft are contacted with the screen drum under a static state, and the end part of the rolling shaft is in transmission connection with a belt wheel at the end part of the revolving shaft through the belt. The screening device provided by the utility model has the advantages that the structure is simple, the flexible belt arranged on the rolling shaft is utilized to continuously hit the outer wall of the screen drum when the revolving shaft is a rotating screening process, screen holes of the screen drum are smooth, and the screening efficiency of the moulding sand is effectively improved.
Description
Technical field:
The utility model relates to the casting manufacture field, relates in particular to a kind of casting sand screening plant.
Background technology:
Molding sand is to be used for the material of moulding in sand casting.Molding sand is generally mixed according to a certain percentage by casting model powder, moulding sand binder and the auxilliary Modeling Material such as thing that adds, also available natural silica sand argillaceous.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.
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 again to cast, and can effectively save cost.
Before all be to utilize manually to sieve sand, inefficiency, the granularity of screening is even inadequately, and in addition, phenomenon often appears intercepting in molding sand sieve aperture in screening process, the efficient of influence screening.
The utility model content:
In order to solve the prior art problem, the purpose of this utility model provides a kind of casting sand screening plant, effectively raises the efficient of screening molding sand.
The technical solution of the utility model is as follows:
The casting sand screening plant, comprise the screen drum that tilts to be installed on support, screen drum one end is charging aperture, the other end is the discharging opening of impurity, discharge port end is lower than feed inlet end, it is characterized in that: on the support of described charging aperture one side motor is installed, roller end in motor and the screen drum is connected by belt transmission, be rotatablely equipped with roller bearing on the support of described screen drum top, the roller bearing outer wall is intervally distributed with flexible band, the flexibility of roller bearing bottom is with when static and is contacted with screen drum, and the roller bearing end is connected by belt transmission with the belt wheel of roller end.
Described casting sand screening plant is characterized in that: on the support of described motor offside feed pipe is installed, feed pipe extend in the charging aperture.
The utility model has the advantages that:
Of the present utility model simple in structure, utilize the flexibility band on the roller bearing to rotate in the process of screening in rotating shaft, constantly impact the screen drum outer wall, guarantee that the screen drum sieve aperture is unobstructed, improved the screening efficiency of molding sand effectively.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Referring to Fig. 1:
The casting sand screening plant, comprise the screen drum 2 that tilts to be installed on support 1, screen drum 1 one ends are charging aperture 3, the other end is the discharging opening 4 of impurity, discharging opening 4 ends are lower than charging aperture 3 ends, on the support of charging aperture 3 one sides motor 5 is installed, roller end in motor 5 and the screen drum 1 is connected by belt transmission, be rotatablely equipped with roller bearing 6 on the support of screen drum 2 tops, roller bearing 6 outer walls are intervally distributed with flexibility and are with 7, the flexibility of roller bearing 6 bottoms is with 7 to contact with the screen drum outer wall when static, and roller bearing 6 ends are connected by belt transmission with the belt wheel of roller end.
On the support of motor 5 offsides feed pipe 8 is installed, feed pipe 8 extend in the charging aperture 3.
