Plastic hot melting device for plastic solidification

Abstract

The invention discloses a plastic hot melting device for plastic solidification. The plastic hot melting device comprises a base and a thermal insulation box, wherein the thermal insulation box is arranged on the base; a hot melting kettle is arranged in the base and the thermal insulation box; the upper part of the hot melting kettle is of an open structure; the lower part of the hot melting kettle is of a semispherical structure; a semispherical placing slot matched with the lower part of the hot melting kettle is formed in the base; a heating device is arranged in the placing slot; the shape of the heating device is matched with that of the lower part of the hot melting kettle, and the heating device clings to the hot melting kettle; a gas ejection pipe is arranged on the inner wall ofthe upper end of the hot melting kettle and is connected with a gas pump; the gas pump is arranged on the outer side of the thermal insulation box; a circulating gas hole is formed in the upper end ofthe hot melting kettle and is connected with the gas pump through a gas pipe; a sealing cover is arranged at the upper end of the hot melting kettle and is articulated to the thermal insulation box;the sealing cover is a pressure-proof sealing cover. The plastic hot melting device disclosed by the invention has a stable structure, can realize quick melting of plastic for solidification and can carry out stirring after start and realize quick discharge so as to ensure plastic stability and meet current requirements of use.

Description

technical field [0001] The invention relates to a hot-melt device, in particular to a plastic hot-melt device for plastic solidification. Background technique [0002] With the development of industry, the hazardous waste discharged from industrial production process is increasing day by day. It is estimated that 330 million tons of hazardous waste are generated worldwide each year. Due to the serious pollution and potential serious impact of hazardous waste, hazardous waste has been called "political waste" in industrially developed countries. The public is very sensitive to the problem of hazardous waste and opposes the establishment of hazardous waste disposal sites in the areas where they live. Disposal of hazardous waste is expensive, and some companies try to transfer hazardous waste to industrially underdeveloped countries and regions. [0003] The magnitude of this transboundary movement of hazardous waste is difficult to quantify, but is clearly growing. Accordin...

Problems solved by technology

First of all, because the waste importing countries basically lack the technical means and economic capacity to deal with and dispose of hazardous waste, the import of hazardous waste will inevitably lead to damage to the local ecological environment and human health.

Secondly, the spread of hazardous waste to underdeveloped areas is actually to evade the disposal responsibility stipulated by the country, so that hazardous waste is not properly treated and disposed of and spread into the environment. The long-term accumulation will inevitably cause harm to the global environment.

[0004] Now there are many ways to deal with these hazardous wastes, but for some dangerous wastes that cannot be processed and recycled by physical and chemical means, they are generally buried after solidification treatment. There are many kinds of solidification treatment processes, among which plastic It is one of them when curing, but the current plastic curing needs to be hot-melted when using plastics. Now the hot-melt equipment is relatively simple, the hot-melt speed is slow, the hot-melt is unstable, and the discharge is difficult, which cannot meet the current use requirements.
