Abstract
The utility model discloses a dynamic rubber powder measuring system of rubber asphalt production equipment; the dynamic rubber powder measuring system can accurately control the addition amount of rubber powder and comprises a charging conveyor line which is composed of a charging machine, a lifting machine and a flow adjusting device arranged between the charging machine and the lifting machine, wherein the flow adjusting device comprises an impact flowmeter, an upper port of the impact flowmeter is connected with a discharging hole of the charging machine, and a lower port of the impact flowmeter is connected with a charging hole of the charging machine; a control valve is arranged at the upper port of the impact flowmeter; and a controller is connected between a control valve and the impact flowmeter. When the addition amount of matrix asphalt changes, the controller processes signals transmitted by the impact flowmeter and then transmits corresponding control signals to the control valve, and the control valve automatically adjusts the opening degree according to the requirement of the controller so as to ensure the addition amount of the rubber powder and the matrix asphalt to be in line with technical requirements.
Description
Technical field
The utility model relates to a kind of rubber powder dynamic measurement system of rubber asphalt production equipment.
Background technology
Rubber asphalt is a kind of novel road materials, and this material is mixed by rubber powder and matrix pitch.According to notice of authorization number is the patent documentation record of CN201276536Y; Rubber asphalt is produced through special equipment; Matrix pitch after its manufacturing process at first will heat up through the premixing system stirs fast, shears, mixes with rubber powder; Then mixture is sent into retort and carry out the high temperature swelling reaction, generate the rubber asphalt finished product.
The effect of feeding system is that rubber powder and additive are joined in the agitator tank of premixing system, and it is mixed with the interior matrix pitch of agitator tank.Because rubber powder must mix according to certain proportioning with matrix pitch and can make the rubber asphalt finished product meet the requirements of quality, therefore, must carry out strict control to the addition of rubber powder.The patent documentation of CN201268682Y discloses a kind of feeding system of rubber asphalt production equipment, and this feeding system comprises feeder, belt conveyer scale and lifting machine, and said feeder and belt conveyer scale, lifting machine are arranged in order the material loading pipeline of component material.Though this feeding system can accurately be controlled the rubber powder addition,, be unfavorable for the miniaturization of rubber asphalt production equipment because the belt conveyer scale area occupied is bigger.
The utility model content
The utility model is to be solved to provide a kind of rubber powder dynamic measurement system that can accurately control the rubber asphalt production equipment of rubber powder addition.
The rubber powder dynamic measurement system of this rubber asphalt production equipment comprises the material loading pipeline of being made up of feeder, lifting machine and the flow regulator between feeder and lifting machine; Said flow regulator comprises impact flow meter; The port of said impact flow meter is connected with the discharging opening of feeder; Lower port is connected with the charging aperture of lifting machine, and the port place of said impact flow meter is provided with control valve, is connected controller between this control valve and the impact flow meter.
The beneficial effect of the utility model is: the open degree of adjusting control valve according to the addition of design; Under the addition of matrix pitch was certain situation, control valve kept fixing open degree, when the addition of matrix pitch changes; The signal that sends through impact flow meter; Handle the back by controller and give the control valve control signal corresponding, control valve according to the requirement adjustment open degree of controller, meets technical requirements with the addition of assurance rubber powder and the addition of matrix pitch automatically.Impact flow meter is arranged between feeder and the lifting machine; Material after the lifting machine measures impact flow meter is raised to the inlet of agitator tank; The approaching amount that finally joins in the agitator tank of rubber powder amount of therefore measuring through impact flow meter, thus the rubber powder addition can accurately be controlled.Because impact flow meter is simple in structure, helps the system integration and the miniaturization of rubber asphalt production equipment.
Description of drawings
Fig. 1 is the structural representation of the rubber powder dynamic measurement system of the utility model rubber asphalt production equipment.
Be labeled as among the figure: lifting machine 1, impact flow meter 2, control valve 3, feeder 4, discharging opening 5, charging aperture 6.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figure 1; The material loading pipeline that feeder 4, lifting machine 1 and the flow regulator between feeder 4 and lifting machine 1 are formed; Said flow regulator comprises impact flow meter 2; The port of said impact flow meter 2 is connected with the discharging opening 5 of feeder 4, and lower port is connected with the charging aperture 6 of lifting machine 1, and the port place of said impact flow meter 2 is provided with control valve 3; This control valve 3 adopts air cylinder driven, and the motion of cylinder is controlled by the controller that is connected with impact flow meter 2.When needs adjusting control valve 3 apertures; Provide detection signal by impact flow meter 2; This detection signal is handled by controller after feeding back to controller again; Give the cylinder control signal corresponding subsequently, make the requirement adjustment open degree of control valve 3, guarantee that the addition of rubber powder and the addition of matrix pitch meet technical requirements according to controller.Wherein, the structure of disclosed feeder and lifting machine is consistent in the patent documentation of the structure of feeder 4 and lifting machine 1 and CN201268682Y.
Claims (1)
1. the rubber powder dynamic measurement system of rubber asphalt production equipment; Comprise by feeder (4), lifting machine (1) and be positioned at feeder (4) and lifting machine (1) between the material loading pipeline formed of flow regulator; It is characterized in that: said flow regulator comprises impact flow meter (2); The port of said impact flow meter (2) is connected with the discharging opening (5) of feeder (4); Lower port is connected with the charging aperture (6) of lifting machine (1), and the port place of said impact flow meter (2) is provided with control valve (3), is connected controller between this control valve (3) and the impact flow meter (2).
