Heat conduction oil type double-cylinder hot melting kettle convenient for replacement of inner containers

Abstract

A heat conduction oil type double-cylinder hot melting kettle convenient for replacement of inner containers comprises hot melting kettle bodies, a gas type stove, an automatic temperature control system and an independent power station. Each hot melting kettle body comprises one inner container, a speed reducer, a stirring shaft, stirring blades, a smoke exhaust pipe, a heat conduction oil storing tank, a heat insulating layer, a protection hearth, a shell, a feeding port and a discharging pipe, an annular cavity is formed between the circumference of the side wall of a stirring barrel and that of the inner wall of the corresponding inner container, a bottom cavity is formed between a baseplate of each stirring barrel and the bottom of the inner wall of the corresponding inner container, and each inner container and the corresponding protection hearth are detachably and fixedly connected through bolts at a connecting block; an opening-closing device is arranged on the outer side wall of each protection hearth, the gas type stove comprises a normally-open-fire stove and an abnormally-open-fire stove, the automatic temperature control system comprises a coating temperature sensor and a heat conduction oil temperature sensor, and the independent power station comprises a traveling chassis assembly, an engine, a hydraulic oil tank assembly, a hydraulic oil pump, a power generator and a heat radiator. The heat conduction oil type double-cylinder hot melting kettle enables total heating area of a coating to be large and uniform, is supportive of replacement of the inner container and can lower cost.

Description

technical field [0001] The invention belongs to the technical field of hot-melt marking construction equipment, and relates to a coating melting equipment before marking. Background technique [0002] For road surface marking, the paint used for marking needs to be heated to a molten state so that it can be coated on the road surface. Striping work on the road requires the use of hot-melt kettles to heat the paint on site. The existing double-cylinder hot-melt kettle has the following deficiencies: 1. There are mainly two heat conduction methods of the existing double-cylinder hot-melt kettle: direct-fired type and heat-conducting oil type. It will cause the coating to solidify, which will affect the construction efficiency and molding effect. The heat transfer oil type has the advantages of strong heat preservation and high safety. The heat is transferred to the coating through the heat transfer oil. The heating is still not uniform enough, and the melting speed of the pa...

Problems solved by technology

The existing double-cylinder hot-melt kettle has the following deficiencies: 1. There are mainly two heat conduction methods of the existing double-cylinder hot-melt kettle: direct-fired type and heat-conducting oil type. It will cause the coating to solidify, which will affect the construction efficiency and molding effect. The heat transfer oil type has the advantages of strong heat preservation and high safety. The heat is transferred to the coating through the heat transfer oil. The heating is still not uniform enough, and the melting speed of the paint needs to be improved; 2. The existing double-cylinder hot-melt kettle body, liner and protective chamber mostly adopt an integrated design. Although the structure is simple, the bottom of the kettle will burn through or age later. The problem is that the entire set of equipment is scrapped or disassembled as a whole, the service life is obviously shortened, and the construction cost of the construction team is increased; 3. The combustion process of the existing double-cylinder hot-melt kettle is mainly controlled by manual control, and it is necessary to observe the melting of the paint manually and always pay attention to the change of material temperature, and at the same time control the amount of gas intake, the cost of manpower construction is high, and the benefit is low
