Improved injection-suction type flue gas cooling mixer for road maintenance and repair

Abstract

The invention provides an improved injection-suction type flue gas cooling mixer for road maintenance and repair, relates to the field of road building machinery, and solves the problem that the smokeabsorption speed cannot be properly adjusted according to the model and material of melt and the problem that the smoke cannot be cooled by adopting a combined cooling method of various cooling structures. The improved injection-suction type flue gas cooling mixer for road maintenance and repair comprises a hot melting kettle, wherein a guide cylinder is welded in the hot melting kettle. Throughthe arrangement of the cooling box structure, due to the fact that the holes are formed in the cooling box structure in the rectangular array shape, the contact area between smoke and the cooling boxstructure can be increased through the arrangement of the holes, and therefore the cooling effect is improved. According to the device, the cooling box structure and the cooling box fixing structure are arranged in a matched mode, when the cooling box structure needs to be taken out, the cooling box structure can be disassembled only by unscrewing the fastening bolts and pulling down the pressingblocks, and therefore the disassembling time of the cooling box structure is saved.

Description

technical field [0001] The invention belongs to the technical field of road construction machinery, and more specifically relates to an improved jet-suction cooling mixer for road maintenance and repair. Background technique [0002] my country's highway traffic network spreads all over the country. The road surface bears the heavy load of various vehicles and is eroded by rain, snow, wind and frost in nature. The road crack sealant hot-melt kettle is one of the necessary equipment for road maintenance. During maintenance, the construction personnel must first perform pretreatment on the damaged and cracked parts of the road surface, and then use the hot-melt kettle equipment to melt the filling materials and send them to the road through the glue outlet pipeline. The joint filling material is injected into the cracks, so that the damaged pavement can be effectively repaired. During the use of the hot melt kettle equipment in the prior art, because the combustion chamber is...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides an improved injector-suction fume cooling mixer for highway maintenance, to solve the problem that the existing problem is that the adjustability is poor, and the above-mentioned application cannot be properly used according to the type and material of the molten material. The adjustment of the absorption speed of the smoke is relatively low; moreover, the cooling effect is poor. The above application can only be mixed and cooled by the swirl mixer, and the cooling effect is single, and it cannot be combined with other cooling methods for joint cooling. The problem
