Technical Field
[0001] The utility model relates to the technical field of metal smelting and casting equipment, in particular to a smelting and casting filtering device. Background Art
[0002] During the metal smelting process, a smelting filter device is required to purify the molten metal and remove impurities. Current smelting filter devices typically use a filter plate fixed in a filter box to filter the molten metal. However, this fixed filter plate can easily become clogged after a period of use, rendering the filtration device unusable. Furthermore, when the filter plate is placed in the filter box, the impact of the molten metal is so strong that it can easily cause the filter plate to shift, resulting in incomplete filtration of the molten metal. Summary of the Invention
[0003] In order to solve the problem that the fixed filter plate in the existing filter box is easily clogged, resulting in the filter device being unusable or the filter plate being easily shifted when placed in the filter box, the utility model proposes a molten casting filter device, wherein a placement groove is opened in the first trough body, the filter plate is placed on the placement groove, and a pressing block is placed on the filter plate. The stability of the placement of the filter plate is improved by the gravity of the pressing block. After the filter plate has been used for a period of time, the pressing block is lifted and a new filter plate is replaced, thereby improving the service life of the filter device.
[0004] In order to achieve the above purpose, the technical solution of the utility model is:
[0005] A smelting and filtering device comprises a filter box, the upper end of which is open, the filter box being provided with a first trough body and a second trough body, a through-trough being provided on the side wall between the first trough body and the second trough body, the through-trough extending to the lower surface of the side wall between the first trough body and the second trough body for connecting the first trough body and the second trough body, the first trough body being connected to a solution inflow trough, the second trough body being connected to a solution outflow trough, the solution inflow trough being higher than the solution outflow trough, the filter box being connected to an external static furnace via the solution inflow trough and to an external casting equipment via the solution outflow trough, the first trough body being provided with a placement slot for placing a filter plate, the filter plate being located below the solution inflow trough and above the through-trough, and a briquette being placed on the filter plate. The molten metal in the static furnace enters the filter box through the solution inflow trough, is filtered by the filter plate, flows downward, flows into the second trough body through the through-trough, and then flows into the casting equipment through the solution outflow trough in the second trough body.
[0006] Furthermore, the first tank body is provided with a plurality of solution inflow slots, each of which is connected to an external static furnace. The plurality of static furnaces work alternately, and when the metal solution needs to be filtered, it can be filtered through a filter box.
[0007] Furthermore, the filter box is placed in a supporting box, and the ends of the solution inflow trough and the solution outflow trough extend out of the supporting box. The supporting box has a heat preservation effect on the metal solution flowing into the filter box, and minimizes the metal solution residue in the filter box.
[0008] Furthermore, the four corners of the lower side of the pressing block are each provided with a pressing portion, and the four pressing portions are located at the four corners of the filter plate, thereby improving the stability of the filter plate and preventing it from shifting under the impact of the metal solution.
[0009] Furthermore, the pressing block is provided with a hoisting hole for connecting to an external hoisting device. The placing and taking out of the pressing block is achieved by the external hoisting device.
[0010] Through the above technical scheme, the beneficial effects of the utility model are as follows: the utility model is provided with a placement groove in the first trough body, a filter plate is placed on the placement groove, a pressing block is placed on the filter plate to improve the stability of the placement of the filter plate, after the filter plate has been used for a period of time, the pressing block is taken out and replaced with a new filter plate, and the filter device can be reused. At the same time, there are multiple solution inflow grooves connected to the first trough body, and each solution inflow groove is connected to an external static furnace, thereby improving the utilization rate of the filter device.

A first trough body 2 and a second trough body 6 are provided in the filter box 1. A through groove 4 is provided on the side wall between the first trough body 2 and the second trough body 3. The through groove 4 extends to the lower surface of the side wall between the first trough body 2 and the second trough body 3 and is used to connect the first trough body 2 and the second trough body 3. In this embodiment, the first trough body 2 and the second trough body 3 are both cavities with square cross-sections, and the bottom surfaces of the first trough body 2 and the second trough body 3 are on the same horizontal plane.
[0019] The first tank body 2 is connected to a plurality of solution inflow slots 5, and the second tank body 2 is connected to a solution outflow slot 6. The solution inflow slots 5 are higher than the solution outflow slots 6. The filter box 4 is connected to an external static furnace through the solution inflow slots 5 and to external casting equipment through the solution outflow slots 6. In this embodiment, there are two solution inflow slots 5, respectively provided on both sides of the filter box 1. Each solution inflow slot 5 is connected to an external static furnace. The filtered metal solution then flows out through a solution outflow slot 6; the bottom surface of the solution outflow slot 6 is flush with the bottom surface of the second tank body 2.
[0020] The first tank body 2 is provided with a placement slot 8 for placing the filter plate 7. The filter plate 7 is located below the solution inflow slot 5 and above the through slot 4. A pressing block 10 is placed on the filter plate 7. The outer periphery of the filter plate 7 is placed exactly in the placement slot 8, and the pressing block 10 is placed above the filter plate 7 to improve the stability of the placement of the filter plate 7. Specifically, the four corners of the lower side of the pressing block 10 are each provided with a pressing portion 11, and the four pressing portions 11 are located at the four corners of the filter plate 7. The pressing block 10 is provided with a lifting hole 12 for connecting to an external lifting device. The placement and removal of the pressing block 10 on the filter plate 7 are both achieved by external lifting equipment.
[0021] In this embodiment, the filter plate 7 is made of ceramic foam material, which is a conventional technical means in this field and will not be described in detail; in addition, the filter box 1 and the pressing block 10 are both made of refractory material (such as aluminum silicate).
[0022] The filter box 1 is placed in a supporting box body 9 , and ends of the solution inflow trough 5 and the solution outflow trough 6 extend out of the supporting box body 9 .
[0023] During use, the molten metal in the static furnace first flows into the first tank body 2 in the filter box 1 through the solution inflow groove 5, and then flows downward after being filtered by the filter plate 7, flows into the second tank body 3 in the filter box 1 through the through groove 4, and then flows into the casting equipment through the solution outflow groove 6 in the second tank body 3.
