Preferably, said discharging pipeline is designed to snakelike pipeline.
Further, said middle sump assemblies also is provided with the compensation discharging opening, and it is used for to said weighing device compensation charging.
Further, being connected with compensation discharging pipeline under the said compensation discharging opening, the other end of said compensation discharging pipeline is communicated with said weighing device.
Preferably, said compensation discharging pipeline is provided with the Pneumatic butterfly valve switch.
Preferably, said compensation discharging pipeline is provided with flow control valve.
Further, said sump assemblies is provided with the weight bracing or strutting arrangement.
Preferably, said weight bracing or strutting arrangement is a hanging steel rope, and it is installed in the top of said sump assemblies.
Preferably, said sump assemblies also is provided with liquid level gauge, when the liquid level of said sump assemblies is lower than the setting liquid level, starts said power set liquid make-up, when the liquid level of said sump assemblies is higher than the setting liquid level, stops said power set feed flow.
Another object of the present invention provides concrete production equipment, and it can provide high-precision liquid Weighing, for this reason, the invention provides following technical scheme:
A kind of concrete production equipment comprises above-mentioned arbitrary liquid feed arrangement of weighing.
With respect to prior art; Advantage of the present invention is following: can realize thick, smart metering; Effectively also improved weighing precision significantly; Overcome the low shortcoming of weighing precision that is usually used in the feed arrangement that liquid weighs at present, can be widely used in construction project that the material proportion weighing precision is had relatively high expectations, like high speed railway construction and subway construction and water conservancy project item construction project.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment, the present invention and useful technique effect thereof are further elaborated, wherein:
Fig. 1 is the existing liquid feed arrangement structural representation of weighing.
Fig. 2 is the liquid of the present invention feed arrangement structural representation of weighing.
Fig. 3 is the structural representation of sump assemblies among the present invention.
The specific embodiment
Like Fig. 2, shown in Figure 3: arrow is depicted as liquid flow direction among the figure.The liquid of the present invention feed arrangement of weighing comprises: liquid feed device 1, power set 2, weighing device 3, sump assemblies 4, feeding pipe 5, discharging pipeline 6, compensation discharging pipeline 7, Pneumatic butterfly valve switch 8, flow control valve 9, liquid level gauge 10, hanging steel rope 11, charging aperture 41, discharging opening 42, compensation discharging opening 43.
Liquid feed device 1 is used to provide liquid, and it is communicated with power set 2 through liquid line; Power set 2 are connected with the charging aperture 41 of sump assemblies 4 through feeding pipe 5; And the liquid of liquid feed device 1 is transported in the sump assemblies 4; The effect of sump assemblies 4 mainly is to make the liquid that flows into sump assemblies 4 betwixt by dynamically becoming static state, stability of flow when making outflow; Discharging opening 42 is set on the sump assemblies 4, and it is connected with weighing device 3 through discharging pipeline 6, and discharging pipeline 6 is set to as shown in Figure 2 snakelike; Impulsive force that can buffered water; Because discharging opening 42 is logical with 41 pairs of charging apertures, so flow is big, charging is fast; Can realize the quick feeding of weighing device 3, practice thrift feed time.
Owing to be difficult to reach desired value through discharging opening 42; And the precision of very difficult full combined feed; Therefore below sump assemblies 4, be provided with compensation discharging opening 43, it is connected with compensation discharging pipeline 7, and is sequentially set with Pneumatic butterfly valve switch 8, flow control valve 9 at compensation discharging pipeline 7.Pneumatic butterfly valve switch 8 can be responded to the metering state of weighing device 3, realizes control automatically, and the discharging flow of 9 pairs of sump assemblies 4 of flow control valve is adjusted, and realizes high weighing precision.When be fed to through discharging opening 42 target a certain amount of after, stop charging, change by the compensation of compensation discharging opening 43 and be fed to weighing device 3, with the way desired value, realized the static compensation charging of weighing device 3, improved weighing precision.
Damage pipeline on the pipeline for preventing that sump assemblies 4 is supported on, hanging steel rope 11 is set above sump assemblies 4, be used for supporting the weight of sump assemblies 4.
For guaranteeing that sump assemblies 4 has material can put and prevent flash, need the liquid level of sump assemblies 4 is carried out perception and control liquid level, therefore be provided with liquid level gauge 10 at sump assemblies 4.When the liquid level of sump assemblies 4 is lower than when setting low liquid level, start said power set 2 liquid make-up, prevent that sump assemblies 4 liquid levels are low excessively, when the liquid level of said sump assemblies 4 is higher than when setting liquid level, stop said power set 2 feed flows, from 6 dischargings of discharging pipeline.And when desired value is lower than a certain setting value (as 10 kilograms), because the desired value amount is too little, discharging pipeline 6 can not satisfy required precision, does not need discharging pipeline 6 this moment, only needs single compensation discharging pipeline 7 feed.
The present invention also provides a kind of concrete production equipment, comprises the above-mentioned liquid feed arrangement of weighing because aforesaid liquid is weighed the feed arrangement metering accurately, so concrete production equipment of the present invention can provide quality requirement higher concrete.
According to the announcement and the instruction of above-mentioned specification, those skilled in the art in the invention can also change and revise above-mentioned embodiment.Therefore, the specific embodiment that discloses and describe above the present invention is not limited to also should fall in the protection domain of claim of the present invention modifications more of the present invention and change.In addition, although used some specific terms in this specification, these terms are explanation for ease just, the present invention is not constituted any restriction.
