FIG. 1 is a schematic view showing a structure of a sand-screening apparatus according to the present invention;
fig. 2 is another schematic structural view of the sand sieving apparatus according to the present invention.
Detailed Description
The following provides a further detailed description of the sand screening device according to the present invention with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.
Example one
The utility model provides a molding sand screening equipment, its structure is as shown in figure 1. The molding sand screening equipment comprises a sand box 1, wherein a feed hopper 2 is arranged at the top of the sand box 1, and the feed hopper 2 is funnel-shaped; a feeding channel 3 extending into the sand box is arranged at the lower end of the feeding hopper 2, specifically, a molding sand crushing mechanism is arranged in the feeding channel 3, the molding sand crushing mechanism comprises three crushing rollers 41, two of the crushing rollers are horizontally arranged, the third crushing roller is positioned below the two crushing rollers, and a crushing gap is reserved between every two crushing rollers; when the molding sand enters from the feed hopper 2, the three crushing rollers 41 rotate synchronously to crush the molding sand.
Specifically, a swinging basket net 5 is arranged in the sand box 1, and molding sand in the sand box is subjected to swinging filtration through the swinging basket net 5, so that the blockage of the conventional fixed filter screen due to accumulation of the molding sand can be avoided; the swinging basket net 5 is positioned below the molding sand crushing mechanism, the swinging basket net 5 is supported by a transverse shaft 51, two ends of the transverse shaft 51 are respectively connected to the side wall of the sand box 1 through bearings 52, and one end of the transverse shaft 51 is electrically connected with a motor 53 through a transmission mechanism; an electromagnet 6 is further arranged in the sand box 1, and the electromagnet 6 is obliquely arranged at the bottom of the sand box 1. And a guide plate 7 is further arranged in the sand box 1 and is positioned below the swing basket net 5 to guide the filtered molding sand to the electromagnet 6. Further, the electromagnet 6 is obliquely arranged at the bottom of the sand box 1 through a support frame A, as shown in FIG. 1; alternatively, as shown in fig. 2, the electromagnet 6 is obliquely mounted on the bottom of the sand box 1 through a sloping plate B. Furthermore, the included angle between the electromagnet 6 and the horizontal plane is 30-40 degrees.
Specifically, the transmission mechanism comprises a transmission wheel 54 and a transmission belt 55, the transmission wheel 54 is installed at one end of the transverse shaft 51, and the transmission wheel 54 is electrically connected with the motor 53 through the transmission belt 55. The motor 53 drives the transmission wheel 54 to rotate through the transmission belt 55, and simultaneously the horizontal shaft 51 rotates to make the swinging basket net 5 swing, so as to filter the molding sand in the swinging basket net 5, leave large particle impurities in the swinging basket net 5, and make the molding sand fall from the swinging basket net 5. A guide plate 7, located below the swinging basket net 5, guides the filtered sand onto the electromagnet 6. The electromagnet 6 is turned on to adsorb metal impurities in the molding sand, and the molding sand slides down under the action of its own weight.
A discharge port is formed in the side wall of the sand box 1 corresponding to the lower end of the electromagnet 6, and a collection box 8 is placed at the discharge port as shown in fig. 1 and 2. The downwardly-slid molding sand falls from the discharge port into the collection box 8. When metal impurities need to be collected, only the electromagnet 6 needs to be powered off, and the metal impurities slide downwards under the action of gravity and slide out of the discharge hole after the adsorption force of the electromagnet 6 is lost.
The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modification and modification made by those skilled in the art according to the above disclosure are all within the scope of the claims.
