Finally, the sand in the recovery tank is recovered into the floating sand box by the recovery pipe.
[0010] This setting method uses high-pressure gas to blow the sand in the recovery tank into the recovery pipe, and finally the recovery pipe recovers the sand in the recovery tank into the floating sand box, which reduces manpower and material resources and effectively improves the recovery efficiency and recovery effect of recovering the sand leaked from the floating sand box into the floating sand box.

DETAILED DESCRIPTION
[0033] The following is combined with Figure 1 -Attached Figure 2 , further details of this application are given.
[0034] Example:
[0035] The present application discloses a sand recovery device for metal casting, referring to Figure 1 , including a recovery tank 1 and a hopper 2. The recovery tank 1 is columnar and hollow inside. The hopper 2 is funnel-shaped. The hopper 2 is vertically mounted on the top of the recovery tank 1 and is connected to the recovery tank 1. An air inlet 3 is provided through the side wall of the recovery tank 1. An air inlet pipe 4 is installed at the air inlet 3. The air inlet pipe 4 is used to inject high-pressure gas into the recovery tank 1. At the same time, a recovery hole 5 is also provided through the side wall of the recovery tank 1. A recovery pipe 6 is installed at the recovery hole 5. One end of the recovery pipe 6 is connected to the recovery tank 1, and the other end of the recovery pipe 6 is connected to the floating sand box.
[0036] Specifically, refer to Figure 1 and Figure 2 A feed hole 7 matching the bottom of the hopper 2 is formed through the top of the recovery tank 1, and the bottom of the hopper 2 is inserted into the feed hole 7, so that the recovery tank 1 and the hopper 2 are connected by the feed hole 7. At the same time, a plug 8 is provided in the recovery tank 1, and the plug 8 is slidably arranged in the direction close to or away from the feed hole 7.
[0037] When the sand material is to be recovered, the hopper 2 is placed under the floating sand box, and the sand material leaked from the floating sand box falls into the hopper 2. At this time, the plug 8 is located below the feed hole 7, and the feed hole 7 is open. The sand material leaked from the floating sand box enters the recovery tank 1 through the hopper 2. After the sand material in the recovery tank 1 is collected enough, the plug 8 is slid toward the feed hole 7, and the feed hole 7 is blocked by the plug 8. Then, high-pressure gas is supplied into the recovery tank 1 through the air inlet pipe 4, and the sand material in the recovery tank 1 is blown into the recovery pipe 6 by the high-pressure gas. Finally, the recovery pipe 6 recovers the sand material in the recovery tank 1 into the floating sand box.
[0038] This arrangement utilizes high-pressure gas to blow the sand in the recovery tank 1 into the recovery pipe 6, and finally the recovery pipe 6 recovers the sand in the recovery tank 1 into the floating sand box, thereby reducing manpower and material resources and effectively improving the recovery efficiency and recovery effect of recovering the sand leaked from the floating sand box into the floating sand box.
[0039] Reference Figure 1 A safety valve 12 is also provided on the top of the recovery tank 1 in the vertical direction. When the air inlet pipe 4 injects high-pressure gas into the recovery tank 1, the safety valve 12 can effectively prevent the gas pressure in the recovery tank 1 from exceeding the specified value, thereby playing an important protective role in personal safety and equipment operation.
[0040] Reference Figure 1 and Figure 2 A recovery plate 9 is added to the recovery tank 1, and the recovery plate 9 is integrally formed on the inner wall of the recovery tank 1. The recovery plate 9 is tilted, one side of the recovery plate 9 is connected to the recovery hole 5, and the side of the recovery plate 9 connected to the recovery hole 5 is located at the lowest point.
[0041] After the sand in the hopper 2 is recovered into the recovery tank 1, it will directly fall onto the recovery plate 9. The recovery plate 9 is set at an angle, and the side of the recovery plate 9 connected to the recovery hole 5 is set as the lowest point of the recovery plate 9. This makes the sand in the hopper 2 fall onto the recovery plate 9 and directly gather at the recovery hole 5. In this way, when enough sand is collected on the recovery plate 9, the high-pressure gas injected into the recovery tank 1 can directly blow the sand at the recovery hole 5 into the recovery pipe 6, and finally recover it into the floating sand box, which is conducive to further ensuring that all the sand on the recovery plate 9 is recovered into the floating sand box, and further ensuring the effect of sand recovery.
[0042] Reference Figure 1 and Figure 2 A driving member 10 is installed in the recovery tank 1 along the vertical direction, and the driving end of the driving member 10 is vertically upward and connected to the plug 8. The driving member 10 is used to drive the plug 8 to slide along the vertical direction in the recovery tank 1. In the embodiment of the present application, the driving member 10 is a cylinder, and the cylinder is used as the driving member 10 for driving the plug 8. The material is common and easy to find, and it is convenient to replace the worn parts.
[0043] Specifically, a corresponding mounting seat is welded in the horizontal direction at the bottom of the driving member 10. When installing the driving member 10, the mounting seat at the bottom of the driving member 10 is fastened to the top of the recovery plate 9 by bolts, and then a connecting rod is welded in the vertical direction between the mounting seat and the top inner wall of the recovery tank 1. The mounting seat and the connecting rod are used to fasten the driving member 10 between the recovery plate 9 and the top inner wall of the recovery tank 1, thereby effectively ensuring the stability of the driving member 10 installed in the recovery tank 1.
[0044] Specifically, refer to Figure 1 A connecting piece 11 is provided between the top of the recovery tank 1 and the hopper 2 in the vertical direction. The recovery tank 1 and the hopper 2 are connected by the connecting piece 11, and the hopper 2 is stably supported on the top of the recovery tank 1.
[0045] In this embodiment, refer to Figure 1 There are multiple connecting pieces 11 between the recovery tank 1 and the hopper 2, and the multiple connecting pieces 11 are evenly distributed along the circumference of the recovery tank 1. The recovery tank 1 and the hopper 2 are connected by multiple connecting pieces 11, thereby effectively ensuring the stability of the connection between the recovery tank 1 and the hopper 2, and at the same time, further strengthening the stability of supporting the hopper 2 on the top of the recovery tank 1.
[0046] Further, refer to Figure 1 A first reinforcement member 111 is horizontally provided between the bottom of the connecting member 11 and the top of the recovery tank 1. The first reinforcement member 111 is plate-shaped and is tightly attached to the top of the recovery tank 1. The first reinforcement member 111 is effectively used to increase the connection area between the bottom of the connecting member 11 and the recovery tank 1, thereby facilitating strengthening the stability of the connection between the bottom of the connecting member 11 and the recovery tank 1.
[0047] Further, refer to Figure 1 A second reinforcement member 112 is provided between the top of the connecting member 11 and the side wall of the hopper 2. The second reinforcement member 112 is in the shape of a plate and is tightly attached to the outer wall of the hopper 2. The second reinforcement member 112 is utilized to effectively increase the connection area between the top of the connecting member 11 and the hopper 2, thereby facilitating strengthening the stability of the connection between the top of the connecting member 11 and the hopper 2.
[0048] In this embodiment, refer to Figure 1 The second reinforcement member 112 is tilted and parallel to the corresponding outer wall of the hopper 2, so that the second reinforcement member 112 can fit tightly to the outer wall of the hopper 2, thereby effectively ensuring a more stable connection between the second reinforcement member 112 and the outer wall of the hopper 2.
[0049] The implementation principle of a sand recovery device for metal casting in the embodiment of the present application is as follows:
[0050] When the sand material is to be recovered, the hopper 2 is placed under the floating sand box, and the sand material leaked from the floating sand box falls into the hopper 2. At this time, the plug 8 is located below the feed hole 7, and the feed hole 7 is open. The sand material leaked from the floating sand box enters the recovery tank 1 through the hopper 2. After the sand material in the recovery tank 1 is collected enough, the plug 8 is slid toward the feed hole 7, and the feed hole 7 is blocked by the plug 8. Then, high-pressure gas is supplied into the recovery tank 1 through the air inlet pipe 4, and the sand material in the recovery tank 1 is blown into the recovery pipe 6 by the high-pressure gas. Finally, the recovery pipe 6 recovers the sand material in the recovery tank 1 into the floating sand box.
[0051] This arrangement utilizes high-pressure gas to blow the sand in the recovery tank 1 into the recovery pipe 6, and finally the recovery pipe 6 recovers the sand in the recovery tank 1 into the floating sand box, thereby reducing manpower and material resources and effectively improving the recovery efficiency and recovery effect of recovering the sand leaked from the floating sand box into the floating sand box.
