Abstract
The utility model relates to a modified asphalt mixing plant with an automatic diatomite adding system, belongs to the filed of mechanical equipment, and in particular to equipment for mixing a road paving material asphalt in highway construction, which comprises asphalt mixing plant equipment and the automatic diatomite adding system, and is characterized in that: the automatic diatomite adding system comprises a hopper, a spiral lifter, a storage silo, a batching room, a batching scale and control equipment, wherein the spiral lifter is formed by a spiral lifting mechanism outside which a cylindrical shell is wrapped and is obliquely arranged on the ground, one end of the spiral lifter on the ground is provided with a hopper which is communicated with an inner cavity of the spiral lifter, the other end of the spiral lifter is provided with a discharge port, the silo is arranged under the spiral lifter, the batching room is arranged below the silo, the batching scale is arranged at the bottom of the batching room and is connected with the control equipment, and the control equipment is connected with a control piece of a silo door. The equipment can be better combined with the traditional asphalt mixing plant equipment, thereby realizing the mechanized production of diatoms modified asphalt.
Description
Technical field
The invention belongs to the plant equipment field, especially a kind of being applied in the highway construction is in order to the equipment of mix highway paver pitch.
Background technology
Flexible pavement has good road-ability, and construction speed fast, easy to maintenance, be beneficial to recycling, therefore be widely used in the road construction of China.But performance characteristics such as easily wear out has also been brought the problem of pitch surfacing because pitch exists high temperature deliquescing, low temperature to become fragile, heat.At these weak points of pitch, just constantly it has been carried out study on the modification since nineteen forties, in pitch, add modifier, auxiliary agent, improve response to temperature, high-temperature stability, low-temperature cracking-resistance and the ageing resistace of pitch.Wherein, utilize kieselguhr to asphalt modification in the present tremendous development that got, the U.S., Germany, Japan and West Europe all making corresponding Modified Bitumen Pavement.Thisly have clear improvement through the road surface of kieselguhr modification hot mastication and low-temperature cracking-resistance, water stability, fatigue life are greatly improved, and have compared high cost performance with prevailing roadway.
In China, the kieselguhr reserves are at the forefront in the world, and diatomite modified asphalt is also had certain research, making the diatomite modified asphalt road surface of certain milimeter number.The modified bitumen on these road surfaces is to mix by the pitch that manually kieselguhr and pitch batching plant equipment mix is gone out to obtain, existing pitch mixing building does not add diatomaceous system automatically, therefore, fail to realize automation completely for the preparation of diatomite modified asphalt.And manually add the stability that diatomaceous destabilizing factor has influenced properties of product to a certain extent, and having influenced quality then by the road surface of its making, simultaneously artificial interpolation also is unfavorable for raising labour efficiency, and reduces labour intensity, saves cost.
Summary of the invention
To be solved in the utility model is exactly not have the problem of adding the kieselguhr system automatically in the existing pitch mixing building equipment, a kind of modified bitumen mixing building that has automatic interpolation kieselguhr system is provided, uses this equipment can Fully-mechanizedly produce pitch through the kieselguhr modification in order to surfacing.
A kind of modified bitumen mixing building that has automatic interpolation kieselguhr system of the present utility model, constitute by pitch mixing building equipment and the automatic kieselguhr system that adds, it is characterized in that adding automatically the kieselguhr system and comprise hopper, screw elevator, feed bin, proportioning room, burden balance and control appliance, screw elevator is made of screw lift outer wrapping one cylindrical shell, tiltedly stand on ground, at its ground one end one hopper being set is communicated with its inner chamber, the other end is provided with a discharging opening, one feed bin is set under it, the feed bin below is a proportioning room, the proportioning room bottom is provided with batch weigher, and burden balance are connected with control appliance, and control appliance is connected with feed bin door control member.
Equipment of the present utility model can combine preferably with existing pitch mixing building equipment and be suitable for, thereby realizes mechanization production diatom modified bitumen.This device structure is simple, and operation is convenient in management for ease of maintenaince.
Description of drawings
Fig. 1 is the structural representation that the utility model adds the kieselguhr system automatically.
Wherein, hopper 1, screw elevator 2, feed bin 3, discharging opening 4, bin outlet 5, proportioning room 6, pitch mix cylinder 7, control appliance 8, burden balance 9, door 10.
The specific embodiment
Embodiment 1: a kind of modified bitumen mixing building that has automatic interpolation kieselguhr system, and by pitch mixing building equipment with add the kieselguhr system automatically and constitute.Automatically add the kieselguhr system and comprise hopper 1, screw elevator 2, feed bin 3, proportioning room 6, batch weigher 9 and control appliance 8.Screw elevator 2 is made of screw lift outer wrapping one cylindrical shell, tiltedly stand on ground, at its ground one end one hopper 1 being set is communicated with its inner chamber, the other end is provided with a discharging opening 4, kieselguhr in the hopper 1 enters the lower end of screw elevator 2 under action of gravity, under the effect of screw lift, kieselguhr taken to screw elevator 2 tops, same under action of gravity, enter in the feed bin 3 that is arranged under it from discharging opening 4, feed bin 3 bottoms are provided with a door 10, and this door 10 is finished the opening and closing operation under the control of control appliance 8.Feed bin 3 belows are proportioning room 6, proportioning room 6 bottoms are provided with batch weigher 9, burden balance 9 are connected with control appliance 8, behind the signal that control appliance 8 receives from batch weigher 9, finish control according to the setting of its control appliance, carry out batch mixing thereby accurately the kieselguhr of certain part by weight is sent into the pitch mix cylinder 7 from proportioning room 6 to door 10.
