Description
One, technical field
The utility model relates to a kind of liquid metering device that is used for concrete central mix plant, and especially a kind of adaptation is used for the concrete mixing plant of Large Scale and Continuous property production.
Two, background technology
In carrying out engineering construction, need to use a large amount of concrete, in order to improve engineering construction speed and to practice thrift cost; All be to use large-scale mixing plant to carry out concrete production now, so concrete central mix plant is an important Architectural Equipment, in order to guarantee quality of concrete; In carrying out concrete production process; It is important means that the liquid that adds is quantitatively controlled, and the liquid metering device that is used for concrete central mix plant is the vitals of concrete central mix plant, at the existing liquid metering device that is used for concrete central mix plant; All be to use constant displacement pump to carry out being metered into of liquid; But, make liquid meter not too accurate, thereby influence quality of concrete because the liquid that constant displacement pump is carried has certain impact.
Three, summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of the utility model provides a kind of liquid metering device that is used for concrete central mix plant, has therefore guaranteed quality of concrete.
For achieving the above object; The technical scheme that the utility model is taked is: include valve; In the efferent duct of constant displacement pump, be provided with the cavity of space greater than efferent duct, be respectively arranged with outlet at the upper and lower side of cavity, the outlet of the upper and lower side of cavity is arranged on liquid the title in the device; Valve is set to be communicated with the lower end outlet of cavity, and valve is set to pneumatic operated valve or motor-driven valve and is set to be connected with the controller of concrete device.
When pump carried out liquid filling, outlet and lower end outlet entered into liquid and claim that this moment is bigger to the impulse ratio of flow symmetry liquid simultaneously from the upper end.When pump carries out liquid filling after a certain amount of, pump stops, and thick gauge line stops output liquid; Valve is not closed on the smart gauge line, continues to be metered into preset variable, owing to designed cavity and valve, has improved the adding precision of liquid, has therefore guaranteed quality of concrete.
The utility model has designed, and includes temporary bucket, thick gauge line and smart gauge line, and temporary bucket is set to infundibulate or flat shape; The arrival end of thick gauge line is arranged on the upper surface of temporary bucket; The arrival end of smart gauge line is arranged on the lower surface of temporary bucket, and the port of export of thick gauge line and smart gauge line is arranged on liquid the title in the device, and thick gauge line is bigger than the outlet diameter of smart gauge line; Smart gauge line is provided with valve, and constant displacement pump is set to be communicated with temporary bucket through pipeline.
Four, description of drawings
Fig. 1 is the sketch map of the utility model.
Five, the specific embodiment
Accompanying drawing is first embodiment of the utility model; Specify present embodiment in conjunction with accompanying drawing; Include and keep in bucket 2, thick gauge line 3, smart gauge line 4 and valve 5, temporary bucket 2 is set to infundibulate, and slightly the arrival end of gauge line 3 is arranged on the upper surface of temporary bucket 2; The arrival end of smart gauge line 4 is arranged on the lower surface of temporary bucket 2; The port of export of thick gauge line 3 and smart gauge line 4 is arranged in the liquid title device, and smart gauge line 4 is provided with valve 5, and constant displacement pump is set to be communicated with temporary bucket 2 through efferent duct 1.
In the present embodiment, valve 5 is set to pneumatic operated valve and is set to be connected with the controller of concrete device.
Need the water of adding or the liquid of additive to pass through constant displacement pump, join earlier in the temporary bucket 2, be drained in the feed bin through thick gauge line 3 again; When quantitatively entering into temporary bucket 2 at last; Because the cushioning effect of constant displacement pump, excess liquid enter into temporary bucket 2, thick gauge line 3 is no longer discharged liquid; Through valve 5 and smart gauge line 4, accurately be drained into liquid in the feed bin.
Among second embodiment of the utility model, temporary bucket 2 is set to flat shape, and valve 5 is set to motor-driven valve and is set to be connected with the controller of concrete device.
The characteristics of the utlity model has down:
1, owing to designed cavity and valve 5, improved the adding precision of liquid, therefore guaranteed quality of concrete.
2, owing to designed the cavity that temporary liquid is arranged on water (or additive) pipeline, be connected with thick gauge line 3 and smart gauge line 4 on the cavity, more than two Guan Junyu cavitys be communicated with, on the smart gauge line 4 ball valve is housed; The utility model is used for the metering of the water and the liquid additive of concrete mixing plant, has improved the measuring accuracy of concrete mixing plant water and additive.
3, owing to designed valve 5, control accuracy is high, and is simple to operate.
4, owing to designed cavity, reduced the cushioning effect of constant displacement pump.
In being used for the liquid metering device technical field of concrete central mix plant; Be provided with the cavity of space greater than efferent duct 1 every including in the efferent duct 1 of pump; Upper and lower side at cavity is respectively arranged with outlet; The outlet of the upper and lower side of cavity is arranged on liquid the title in the device; Valve 5 is set to be communicated with the lower end outlet of cavity, valve 5 be set to pneumatic operated valve or motor-driven valve and the technology contents that is set to be connected with the controller of concrete device all in the protection domain of the utility model.
