The furnace comprises a melting device and a purifying device; the purifying device comprises a water mist spraying purifier, an air separation dust remover, a bag-type dust remover, an activated carbon adsorption box, a photo-oxidation catalytic purifier and an induced draft fan which are sequentially arranged from right to left, wherein the water mist spraying purifier, the air separation dust remover, the bag-type dust remover, the activated carbon adsorption box, the photo-oxidation catalytic purifier and the induced draft fan are sequentially connected through pipelines; the melting device comprises a melting furnace body, lifting structures are arranged on the left side and the right side of the melting furnace body, furnace doors are assembled on the lifting structures, and movable furnace beds are arranged on the outer sides of the lifting structures; and a driving device, the water mistspraying purifier, the air separation dust remover, the bag-type dust remover, the activated carbon adsorption box, the photo-oxidation catalytic purifier, the induced draft fan, radiation heating pipes and a steel wire rope winch are all powered on and are connected with a controller. According to the furnace, gasified harmful gas is purified, and the EPS lost foam production quality is improved.

Description

technical field [0001] The invention belongs to the technical field of precision casting industrial equipment, and in particular relates to an environment-friendly special furnace for melting EPS lost foam. Background technique [0002] EPS lost foam casting (also known as solid mold casting) is a solid mold casting in which foam plastic molds use binder-free dry sand combined with vacuum pumping technology. After the paint is dried, it is buried in dry quartz sand for vibration molding, poured under negative pressure to vaporize the model, and the liquid metal occupies the position of the model, solidifies and cools to form a casting. Compared with the traditional casting technology, the new casting method has the following characteristics: 1. Good casting quality and low cost; 2. Unlimited material and suitable size; 3. High dimensional accuracy, smooth surface and less cleaning; 4. The internal defects are greatly reduced and the organization is dense; 5. Large-scale and...
