Description
Technical Field
The invention relates to the field of asphalt mixing equipment, in particular to a modifier dry-method feeding device for high-performance asphalt mixture of an asphalt mixing station.
Background
Asphalt mixing stations, which may also be referred to as asphalt concrete mixing stations, refer to complete equipment for mass production of asphalt concrete, and can produce asphalt mixtures, modified asphalt mixtures, colored asphalt mixtures, which are necessary equipment for constructing highways, grade highways, municipal roads, airports, and ports.
The continuous development of economy and society puts forward higher requirements on the service quality and the service level of the road asphalt pavement, and the development planning of the modern comprehensive transportation system definitely puts forward the improvement of the service life of the infrastructure. The high-performance asphalt mixture is an indispensable material for prolonging the service life of the highway asphalt pavement and realizing the target of the long-service-life asphalt pavement.
The main production method of the high-performance asphalt mixture is a wet prefabrication process and a dry process. For the wet prefabrication process, firstly, a modifier is added into matrix asphalt in a modified asphalt factory, and after the modifier is fully swelled, ground and developed and crosslinked by using a large-scale shearing machine or colloid mill equipment, the finished high-performance modified asphalt is prepared and then transported to an asphalt mixing station for on-site storage and use. The wet prefabrication process has the problems that the modifier is decomposed by heating, separated from asphalt and the like. The dry process can solve the technical problems of the wet prefabrication process by directly putting the fast-dissolving dry modifier into a mixing station, is simple and easy to operate, is not limited by the transportation distance and the storage time of the wet process, and becomes one of the main modes of producing the high-performance asphalt mixture, and has huge social requirements.
In order to reduce dusting, modifiers are generally bagged. As shown in fig. 1, since the mixing station 12 is large and the feeding port 14 is high, the modifier needs to be lifted by the Z-type conveyor 2, and then conveyed to the feeding port 14 by the declining slideway 3, and a material blocking mechanism is arranged at the output end of the declining slideway 3 for controlling the feeding rhythm. Fig. 2 shows a schematic structural diagram of a modifier feeding device of an existing asphalt mixing station, so that the modifier feeding device can be suitable for a large volume of modifier, the height difference between a discharge hole of a Z-shaped conveyor 2 and a declining slide way 3 is large, and the impact force caused by falling of the modifier is very easy to cause breakage of a modifier packaging bag, thereby causing dust emission and seriously polluting construction environment.
Disclosure of Invention
The invention aims to solve the defects in the prior art, and provides a modifier dry-method feeding device for high-performance asphalt mixture of an asphalt mixing station, which is provided with a buffer guiding mechanism with a unidirectional damping effect, when an additive falls, a unidirectional damper provides damping force to reduce the impact force of the falling modifier, so that dust emission is reduced; when the contact plate is reset, the unidirectional damper does not apply acting force to the contact plate, so that the contact plate is quickly reset, and the throwing efficiency is improved.
The technical problems to be solved are realized by adopting the following technical scheme: the modifier dry-method throwing device for the high-performance asphalt mixture of the asphalt mixing station comprises a frame, a Z-shaped conveyor, a declining slideway and a buffering guiding mechanism; the Z-shaped conveyor and the downward-inclined slide way are both arranged on the frame, and the downward-inclined slide way is in butt joint with the lower part of a discharge hole of the Z-shaped conveyor; the buffer guide receiving mechanism is arranged between a discharge hole of the Z-type conveyor and the downward-inclined slide way, and comprises a guide receiving plate, a unidirectional damper and a reset tension spring, wherein the guide receiving plate is arranged on the downward-inclined slide way in a swinging manner, and the reset tension spring is respectively connected with the downward-inclined slide way and the rear end of the guide receiving plate; when the guide plate swings downwards relative to the downward-inclined slideway, the unidirectional damper applies constant damping force to the guide plate; when the guide plate swings upwards relative to the declination slide way, the unidirectional damper does not apply force to the guide plate.
Compared with the prior art, the modifier dry-method feeding device for the high-performance asphalt mixture of the asphalt mixing station has the beneficial effects that: (1) The modifier falls on the guide plate by the Z-shaped conveyor, so that the guide plate swings downwards, the unidirectional damper provides damping force to enable the guide plate bearing the modifier to slowly overturn downwards, and then the modifier slides onto the downward inclined slideway from the inclined guide plate, so that the impact force of the falling of the modifier can be reduced, and dust emission is reduced; when the contact plate is reset, the unidirectional damper does not apply acting force to the contact plate, so that the contact plate can be quickly reset, and the throwing efficiency is improved. (2) In actual working conditions, the weight of the modifier is different according to the requirement of the throwing process. If a spring is used to provide a damping force, a spring with a large elastic force is required to achieve the buffer connection of the heavy modifier, but according to hooke's law, the elastic force (damping force) is in a linear relationship with the deformation amount of the spring, and thus, a situation may occur in which the connection plate cannot swing down to a predetermined position, thereby causing the apparatus to stop. The unidirectional damper can provide constant damping force, and can prevent equipment from being stopped due to the fact that the connecting plate cannot swing downwards to a preset position on the premise of providing enough damping force. (3) The unidirectional damper disclosed by the invention has the advantages of simple structure, low cost, no need of electric control and longer service life under severe working conditions of more dust.
