Background technology
In the concrete mixing plant production process, because the defective phenomenon of the malfunctioning concrete quality that causes of liquid additive metering system happens occasionally, the additive scale is malfunctioning following several reason: (1) sensor damages; (2) the discharging butterfly valve damages; (3) the feed water pump is malfunctioning.Because traditional additive scale is hung above the water weighing hopper or above the main frame, after the additive scale is malfunctioning, can cause excessive additive to enter in water scale or the mixer, thereby cause the concrete quality accident.
The utility model content
The purpose of this utility model provide a kind of easy for installation, fundamentally solve the additive weigher Pneumatic conveyer that the malfunctioning back of additive scale has a negative impact to concrete.
The technical solution of the utility model is: additive weigher Pneumatic conveyer, it is characterized in that forming by scale body, feed arrangement and drawing mechanism, wherein the scale body is made up of casing, weighing hopper, sensor, and weighing hopper is positioned at the inside of casing, and sensor is installed on the weighing hopper; Feed arrangement is made up of check valve, flexible pipe, feed pipe, and feed pipe links to each other with weighing hopper, and check valve is connected with feed pipe by flexible pipe; Drawing mechanism is made up of magnetic valve, air inlet pipe and discharge nozzle, and discharge nozzle is connected with weighing hopper, and magnetic valve is connected with weighing hopper by air inlet pipe.
Described magnetic valve is three two-way valves, leads to compressed air during the magnetic valve energising in weighing hopper, during the magnetic valve outage, communicates with atmosphere in the weighing hopper.
Discharge nozzle is connected with the lower end outlet of weighing hopper.
Effect of the present utility model is: additive weigher Pneumatic conveyer, to form by scale body, feed arrangement and drawing mechanism, and the scale body is made up of casing, weighing hopper, sensor, and weighing hopper is positioned at the inside of casing, and sensor is installed on the weighing hopper; Feed arrangement is made up of check valve, flexible pipe, feed pipe, and feed pipe links to each other with weighing hopper, and check valve is connected with feed pipe by flexible pipe; Drawing mechanism is made up of magnetic valve, air inlet pipe and discharge nozzle, and discharge nozzle is connected with weighing hopper, and magnetic valve is connected with weighing hopper by air inlet pipe, and magnetic valve also is connected with feed pipe by pipeline.
The principle that adopts big or small cavity pressure to equate is utilized the metering cylindrical shell sectional area different with discharge nozzle, feeds the compressed air of low pressure in weighing hopper, the liquid in the weighing hopper can be delivered to the operation principle in high-altitude and carry additive; Weighing hopper can be placed on any rational position, and is easy for installation, fundamentally solved additive and claimed the adverse effect that malfunctioning back produces concrete.
Below in conjunction with drawings and Examples the utility model is described further.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
In the accompanying drawing, additive weigher Pneumatic conveyer is made up of scale body, feed arrangement and drawing mechanism, and wherein the scale body is made up of casing 1, weighing hopper 2, sensor 3, and weighing hopper 2 is positioned at the inside of casing 1, and sensor 3 is installed on the weighing hopper 2; Feed arrangement is made up of check valve 4, flexible pipe 5, feed pipe 6, and feed pipe 6 links to each other with weighing hopper 2, and check valve 4 is connected with feed pipe 6 by flexible pipe 5, and check valve 4 can only can not flow backwards to the charging of scale body; Drawing mechanism is made up of magnetic valve 7, air inlet pipe 8 and discharge nozzle 9, and discharge nozzle 9 is connected with the lower end outlet of weighing hopper 2.Magnetic valve 7 is connected with weighing hopper 2 by air inlet pipe 8.Magnetic valve 7 is three two-way valves, leads to compressed air during the magnetic valve energising in weighing hopper, during the magnetic valve outage, communicates with atmosphere in the weighing hopper.
Operation principle of the present utility model is:
When beginning to measure, material enters in the metering bucket body 2 by feed pipe 6, flexible pipe 5 and check valve 4, and this moment, air-operated solenoid valve was in off-position.Therefore the gas in the weighing hopper can communicate with atmosphere by the magnetic valve passage, does not cause and forms malleation in the weighing hopper.The weight of material that enters is converted into data signal by sensor and is transported in the microcomputer, and when being metered into rated value, microcomputer sends instruction, stops feed.During the beginning discharge, magnetic valve 7 energisings, compressed air enters in the metering cylindrical shell 2 by tracheae 8.Because the effect of air pressure, check valve 4 is closed, measure this moment between interior liquid level of bucket body and the top cover and form an airtight space, pressure raises, weighing hopper bottom discharge pipe communicates with atmosphere, the principle that adopts big or small cavity pressure to equate is utilized weighing hopper and discharge body different cross-sectional, and the material in the bucket body will be discharged fast along drainage conduit 9.
