[0030] The pressing mechanism 213 is arranged on the smelting furnace 2, the pressing mechanism 213 comprises a vertical driving unit 2134 and a pressing plate 2135 connected to the output end of the vertical driving unit 2134, the pressing plate 2135 is located above the first area 22, the vertical driving unit 2134 can drive the pressing plate 2135 to keep vertical movement, and the waste blocks in the first area 22 are pressed below the metal liquid surface of the smelting furnace 2 by driving the pressing plate 2135 to keep vertical downward movement.

[0031] The pushing mechanism 214 is arranged on the smelting furnace 2, the pushing mechanism 214 comprises a horizontal driving unit 2143 and a pushing plate 2147 connected to the output end of the horizontal driving unit 2143, the horizontal driving unit 2143 drives the pushing plate 2147 to keep movement, and then the metal liquid and the waste blocks in the second area 23 enter the third area 24 through the filter holes 25 on the filter baffle 212.

[0032] The utility model, the first area 22 is waste input area, after the waste is put into the smelting furnace 2, the vertical driving unit 2134 of pressing mechanism 213 drives the pressing plate 2135 to keep vertical downward movement, so that the waste block sinks and flows to the second area 23, in the process of waste block flow, a certain melting is carried out through the heating action of smelting furnace 2, then the horizontal driving unit 2134 of pushing mechanism 214 drives the pushing plate 2147 to keep horizontal movement, and the waste blocks after a certain melting are pushed from the second area 23 to the third area 24 through the filter holes 25 on the filter baffle 212, ensure that only a part of waste is pushed into the third area 24 each time, can ensure that the third area 24 of smelting furnace 2 has both the metal liquid that originally melts sufficiently and a part of waste blocks after melting, after using a part, mix new waste blocks again, can ensure that the third area 24 of smelting furnace 2 contains a part of waste blocks, and the composition of waste blocks will not be too much, can reduce the material cost while ensuring a certain product quality.

[0040] In the production process, when the waste block in the first area 22 flows into the second area 23, the third slider 2145 is driven downward by the vertical drive mechanism 2148, so that the push plate 2147 extends into the metal liquid surface of the second area 23, and then the second slider 2142 is driven to move by the horizontal drive unit 2143, so that the push plate 2147 keeps horizontal movement, and the metal liquid and waste block in the second area 23 are pushed into the third area 24 through the filter hole 25.

[0043] After the waste block is put into the first area 22, the waste block is melted to a certain extent by the heating action of the smelting furnace 2;

[0044] The first slider 2132 is then driven to keep vertical downward movement in the vertical support base 2131 by the vertical driving mechanism 2148, and the first connecting rod 2133 is synchronously driven to keep vertical downward movement, so that the downward pressing plate 2135 presses the waste block floating on the metal liquid surface in the smelting furnace 2 downward to the metal liquid surface;

[0045] Since the depth of the blocking baffle 211 is less than the depth of the filtering baffle 212, when the liquid in the first area 22 is pressed downward, the metal liquid in the first area 22 flows towards the second area 23, and at the same time, the waste block flows from the first area 22 to the second area 23, and then the vertical driving mechanism 2148 is reset to prevent the downward pressing plate 2135 from being excessively heated in the smelting furnace 2;

[0046] The third slider 2145 on the vertical seat 2144 is then driven to keep vertical downward movement by the vertical driving mechanism 2148, and the second connecting rod 2146 is driven to move downward, and the pushing plate 2147 is pushed into the metal liquid surface of the second area 23;

[0047] The second slider 2142 is then driven to keep movement by the horizontal driving unit 2143, and the vertical seat 2144 is driven to move, so that the pushing plate 2147 keeps horizontal movement, and the metal liquid and the waste block in the second area 23 are pushed into the third area 24 through the filtering hole 25;

[0048] The vertical driving mechanism 2148 is then reset, and the horizontal driving unit 2143 is reset.
