Abstract
A kind of bitumen aggregate ratio control device applied to continuous asphalt mixing plant, including weighing sensor, belt conveyor and control terminal, belt conveyor is installed on weighing sensor, the feed inlet of belt conveyor is docked with the belt outlet that gathers materials of cold burden bucket lower part, the discharge port of the belt conveyor is docked with inclined belt conveyer entrance, and weighing sensor is connect with control terminal.The belt conveyor of the utility model integrally floats on above weighing sensor, it avoids because of influence of the factors to measuring accuracy such as belt tension size, carrying roller height errors, the weight data which obtains relatively accurate can reflect that the output accumulated error in all cold burden storehouses and the final of all cold burden storehouses summarize yield.Weight signal is fed back to control terminal by weighing sensor simultaneously, and control terminal automatically adjusts the flow of pitch according to the flow of aggregate and other existing parameters, to realize accurately controlling for bitumen aggregate ratio.
Description
Technical field
The utility model is related to asphalt production equipment technical fields, more specifically refer to that one kind being applied to continous way drip
The bitumen aggregate ratio control device of green mixture stirring device.
Background technology
Continuous asphalt mixing plant typical process flow exactly by sand material according to Engineering Mixed Proportions require into
After the metering of row continous way, conveying, heating mixture is stirred into together with the raw material such as pitch, mountain flour.This mixture is to material
Between proportionate relationship require relatively high, require ratio especially for proportional precision of the pitch as binder in mixture
It is higher.The weight of pitch generally uses flowmeter to detect, and pitch content, pitch and bone are controlled by adjusting the rotating speed of bitumenpump
The proportionate relationship of material is commonly referred to as bitumen aggregate ratio.The feeding belt of cold bin bottom is usually used to control in the metering method of aggregate
System.The cold burden system equipment of a set of equipment is usually made of 4 to 6 cold burden storehouses.The feeding belt of these cold bin bottoms is general
All carry continous way function of weighing.
The measuring accuracy of the continous way weighing device of this feeding belt for being placed in cold bin bottom is often by very much
The influence of factor, these factors include：Temporary aggregate in feed bin is to the pressure of bin bottom feeding belt, of feeding belt
Of different sizes, floating idler roller high and low position difference of clamp force etc.；Inevitably there is certain meter when carrying out match ratio control in each storehouse
Measure error.These error accumulations are got up, and the measuring accuracy of aggregate will be very low for complete equipment, are finally stirred out and
Finished product material oilstone ratio error will be bigger.
Invention content
The utility model provides a kind of bitumen aggregate ratio control device applied to continuous asphalt mixing plant, master
Aim to overcome that the continous way weighing of existing aggregate is influenced by feeding belt tensile force, floating idler roller position difference and caused
Measuring accuracy is low, it is larger so as to cause finished product material oilstone ratio error the shortcomings of.
The utility model adopts the following technical solution：
A kind of bitumen aggregate ratio control device applied to continuous asphalt mixing plant, including weighing sensor, skin
Band conveyer and control terminal, the belt conveyor is installed on the weighing sensor, the belt conveyor into
Material mouth is docked with the belt outlet that gathers materials of cold burden bucket lower part, discharge port and the inclined belt conveyer entrance pair of the belt conveyor
It connects, the weighing sensor is connect with the control terminal.
Further, the weighing sensor includes a plurality of, and the weighing sensor is distributed on the belt conveyor
Lower section.
Further, the control terminal is computer control.
Further, the computer control also respectively with the belt conveyor, gather materials belt and belt slope it is defeated
Send machine control connection.
By the above-mentioned description to the utility model structure it is found that compared to the prior art, the utility model has following excellent
Point：Gather materials belt conveyor of the utility model in cold burden bucket lower part adds a set of whole peace with oblique belt conveyor docking location
Belt conveyor above weighing sensor, can be to collection stream that aggregate supply system is brought by this belt conveyor
Amount carries out continous way and weighs.Since this belt conveyor integrally floats on above weighing sensor, avoid because belt tension is big
The influences of the factors to belt metering device measuring accuracy such as small, carrying roller height error, the weight data which obtains
It relatively accurate can reflect that the output accumulated error in all cold burden storehouses and the final of all cold burden storehouses summarize yield.Claim simultaneously
It retransmits sensor and weight signal is fed back into control terminal, control terminal is adjusted automatically according to the flow of aggregate and other existing parameters
The flow for saving pitch, to realize accurately controlling for bitumen aggregate ratio.
Description of the drawings
Fig. 1 is the scheme of installation of the utility model.
Specific implementation mode
Illustrate specific embodiment of the present utility model with reference to the accompanying drawings.For comprehensive understanding the utility model, below
Many details are described to, but to those skilled in the art, the utility model can be also realized without these details.For public affairs
Component, method and the process known, are not described in detail below.
A kind of bitumen aggregate ratio control device applied to continuous asphalt mixing plant, referring to Fig.1, including biography of weighing
Sensor 10, belt conveyor 20 and control terminal 30, the belt conveyor 20 are installed on the weighing sensor 10, institute
It includes a plurality of to state weighing sensor 10, and a plurality of weighing sensors 10 are distributed on the lower section of the belt conveyor 20, by skin
Band conveyer 20 stablizes support.The weighing sensor 10 and belt conveyor 20 can convey the collection to come to aggregate supply system
Stream amount carries out continous way and weighs.
Referring to Fig.1, the feed inlet of the belt conveyor 10 is docked with the outlet of belt 1 that gathers materials of cold burden bucket lower part, the skin
Discharge port with conveyer 20 is docked with 2 entrance of inclined belt conveyer.Above-mentioned weighing sensor 10 and the control terminal 30
Connection, the control terminal 30 are preferably computer control.Signal after weighing sensor 10 is weighed feeds back to computer control
Device processed, computer control automatically adjusts the flow of pitch according to the flow of aggregate and other existing parameters, to realize oil
Stone than accurately control.
Computer control also respectively with the belt conveyor 20, gather materials belt 1 and inclined belt conveyer 2 control connect
It connects, the conveying speed for automatically adjusting belt conveyor 20, gather materials belt 1 and inclined belt conveyer 2.
The above is only the specific embodiments of the present invention, but the design concept of the present invention is not limited thereto,
All non-essential modifications to the present invention made by this concept should all belong to the row for invading scope of protection of the utility model
For.
