Description

[Detailed description of the invention] The present invention provides a platform for receiving casting sand, with its blind receiving surface being lower on the edge side, so that it can be freely driven and vibrated up and down or diagonally up and down. The present invention relates to a casting sand separation and recovery device in which an opening for discharging finely divided casting sand is provided in a side wall of the stand.

The above device is compact and easy to handle, such as cleaning and repairing, without causing any trouble. This is what I proposed earlier.

(See Utility Model Application No. 173036/1983). The present invention has further improved the above-mentioned device, and has a function of separating the sand from the castings and the metal frame on the table, a crushing function for the separated sand, and a function of separating the sand from the discharge port. The aim is to improve all conveyance functions at once and greatly increase processing capacity.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

As shown in FIGS. 1 to 3, a platform 1 for receiving casting sand is fixed to a fixed base via a large number of compression springs 2, with its blind receiving surface 1a being lower on the edge 1b side. A bracket 4 is attached to the lower surface of the stand 1, and two vibration motors 5 each having an eccentric weight attached to the rotating shaft are suspended from the bracket 4, and the motors 5 are connected to the stand 1. The table 1 is designed to be driven and vibrated obliquely up and down A so that the downward side of the receiving surface 1a becomes higher as the receiving surface 1a rotates downward.

A plurality of ribs 6 on which a cast product with casting sand or a metal frame is placed are arranged in parallel on the stand 1 in such a manner that they extend in an inclined direction B with respect to the receiving surface 1a and protrude upward, and the upper ends 6a of the ribs 6 are arranged horizontally or almost horizontally in the inclination direction B of the receiving surface 1a.

A side wall 7 bent in the vertical direction is erected on the stand 1, positioned on one end edge 1b side where the receiving surface 1a is lowered, and a relatively small opening 8 for discharging finely divided casting sand is provided in the side wall 7.
The lower part of the gold mine is located in parallel above the hopper 10 that supplies the crusher 9, and is vertical or close to it. As, and an inclined portion 7b extending above the portion 7a are formed on the upper inner surface of the side wall 7.

Note that instead of the vibration motor 5, various drive configurations can be used, such as one using an eccentric shaft, and the vibration direction of the table 1 may be in the vertical direction.

Instead of the ribs 6, for example, as shown in FIGS. 4 and 5, a large number of protrusions 11 may be arranged in parallel on the base 1. In short, the protrusions 6, 11 are arranged above the receiving surface 1a. Further, the upper end portion 6 is formed so as to protrude from the receiving surface 1a and form a gap through which the cast iron ingot can pass, which is continuous in the inclination direction B along the receiving surface 1a.
a, lla may be provided horizontally or substantially horizontally in the receiving surface inclination direction B, and the protrusions 6, 11 and the stand 1 may be constructed as separate bodies.

The shape of the side wall 7 and the shape and arrangement of the opening 8 can be changed in various ways, and the side wall 7 and the stand 1 can be configured separately.
Alternatively, the side wall 7 may have a divided configuration.

In summary, the present invention provides the casting sand separation and recovery apparatus described above, in which the protruding bodies 6, 11 on which cast iron-attached castings and metal frames are placed are in a state of protruding above the receiving surface 1a and 1
The upper end portions 6 of the protrusions 6, 11 are arranged in parallel on the table 1 with a gap continuous in the inclination direction B along the a.
a, 11a are arranged horizontally or almost horizontally in the receiving surface inclination direction B, and the inner surface of the side wall 7 has a vertical or nearly vertical portion 7a and an inclined portion 7b extending above the vertical portion 7a. It is characterized by

That is, the cast iron can be efficiently separated from the cast product and the metal frame by the impact action of the protrusions 6 and 11, and the separated cast iron passes between the protrusions 6 and 11 without the cast product and the metal frame becoming an obstacle. In addition, due to the conveying action of the inclined receiving surface 1a, the finely divided cast iron is quickly sent to the discharge port 8 side, and the finely divided cast iron is quickly dropped and collected from the hopper 10 to the crusher 9, and the cast iron that has not been sufficiently finely divided is After the lump is pushed up along the inner side wall portion 7a by the pressing action of the subsequent cast iron, it is reversed and dropped by the action of the inclined portion 7b, and is efficiently divided into pieces by the impact of the fall.

In addition, since the upper ends 6a and lla of the protrusions 6 and 11 are horizontal or nearly horizontal in the receiving surface inclination direction B, lateral movement of the cast product and the metal frame is suppressed, and this also prevents the cast iron from opening 8. The discharging of the cast iron and the reversal and falling of the cast iron ingots into smaller pieces are carried out efficiently, and overall the cast iron separation and recovery capacity can be greatly increased.
