[0028] In this embodiment, by providing an overflow cover 12, harmful gases, water vapor, and dust generated inside the sand bucket 11 are blocked and prevented from overflowing into the production workshop. A slider 13 allows the overflow cover 12 to be moved easily. Two fans 17 are provided and fixedly installed inside the gas supply pipe 15 and the processing box 16, respectively.

The locking rod 32 is provided and can engage with the slider 13, so the anti-overflow cover 12 can remain stable under the action of the locking rod 32 and the slider 13.

[0029] Example 2

[0030] like Figures 1-5 As shown, the treatment box 16 is equipped with a water-filled cotton block 24, which is fixedly connected to the connecting plate 23. The treatment box 16 is also equipped with an alkali-filled cotton block 25, which is fixedly connected to the connecting plate 23.

The first bolt 26 is slidably connected to the connecting plate 23 and threadedly connected to the treatment box 16. A second bolt 27 is fitted between the sealing cover 21 and the inside of the treatment box 16. The second bolt 27 is slidably connected to the sealing cover 21 and threadedly connected to the treatment box 16.

[0031] In this embodiment, by setting up the processing mechanism 2, the harmful gases and water vapor transmitted into the processing box 16 can be processed. The water-filled cotton block 24 is set up, and the water-filled cotton block 24 can collect water vapor, aldehyde gas and ammonia gas. At the same time, the alkali-filled cotton block 25 is set up, and the alkali-filled cotton block 25 has strong alkalinity. Thus, the alkali-filled cotton block 25 can collect sulfur dioxide and phenol gas, so that the gas that finally passes through the processing box 16 does not contain harmful gases, and the air in the processing workshop meets the health standards. In addition, the first bolt 26 and the second bolt 27 are set up to facilitate the installation and removal of the sealing cover 21 and the connecting plate 23.

[0032] Working principle:

[0033] like Figures 1-5As shown, in use, the coated sand mold is first placed inside the sand bucket 11, and then the gate of the casting mold is attached to the coated sand mold. Fine sand is then added to the sand bucket 11. At this time, the overflow cover 12 is installed along with the slider 13, so that the overflow cover 12 fits onto the outer surface of the sand bucket 11, and the slider 13 is positioned within the groove on the sand bucket 11. Then, the pull block 35 is pulled, causing the locking rod 32 to slide. The locking rod 32 simultaneously moves the limiting ring 33, which compresses the spring 34, generating elasticity. The overflow cover 12 is then positioned appropriately, and the locking rod 32 is engaged with the slider 13 upon reset. The pull block 35 is then released, and the elasticity of the spring 34 is instantly released, automatically resetting the locking rod 32 so that it engages with the inner part of the slider 13. The two anti-overflow covers 12 are then kept stable, and the gate of the casting mold is placed between the two anti-overflow covers 12. Molten metal is then poured into the gate. As the temperature rises, a large amount of harmful gases, water vapor, and dust are generated inside the sand bucket 11. At this time, two fans 17 are started. Under the action of the fans 17, a negative pressure is formed inside the gas supply pipe 15 and the treatment box 16. As a result, the harmful gases, water vapor, and dust in the sand bucket 11 are drawn in and enter the treatment box 16. At this time, the dust is collected by the dust filter belt 19, while the water vapor, aldehyde gas, and ammonia gas are collected and treated by the two water-filled cotton blocks 24. At the same time, sulfur dioxide and phenol gas are collected and treated by the two alkali-filled cotton blocks 25. Thus, the harmful gases, water vapor, and dust generated inside the sand bucket 11 are effectively treated, and the gas emitted into the air fully meets the emission standards.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
