Abstract
The utility model discloses a liquid measuring and adding device of a mixing plant. The liquid measuring and adding device of the mixing plant comprises a measuring tank body, wherein electronic scales for weighing liquid are arranged on the measuring tank body; a liquid inlet pipe is arranged at the upper part of the measuring tank body; a liquid outlet pipe is arranged at the lower part of the measuring tank body; the measuring tank body is a sealed tank body; a gas inlet pipe and a blowoff valve are arranged at the upper part of the measuring tank body; and the gas inlet pipe is connected with a gas source through a gas inlet valve. The liquid measuring and adding device of the mixing plant has the characteristics of simple structure, low cost, high liquid conveying pressure, high speed, no liquid residue in the tank body and the like.
Description
Technical field
The utility model belongs to the metering device technical field.Be specifically related to a kind of mixing plant liquid meter adding set.
Background technology
At present, the liquid meter adding set of asphalt concrete mixer and Cement Concrete Mixing all adopts the electronic scale metering liquid, with pump the liquid that metering finishes is delivered to mixer afterwards, the liquid that perhaps allows metering finish flows to mixer certainly, metering device with pumping liquid, its complex structure, it is bigger to conduct oneself with dignity, the cost height.Because pump delivery is limited, make rate of pumping slow simultaneously, pressure is low, is unfavorable for boosting productivity.Though adopt the metering device of gravity flow mode simple in structure, its pressure is lower, and is consuming time longer.
Summary of the invention
For solving the above-mentioned defective that prior art exists, it is a kind of simple in structure that the purpose of this utility model is to provide, low cost, interpolation speed height, the mixing plant liquid meter adding set that reliability is high.
For achieving the above object, the technical solution adopted in the utility model is: this mixing plant liquid meter adding set, has the metering tank body, described metering tank body is provided with the electronic scale for the weighing liquid weight, the top of metering tank body is provided with feed tube, and the bottom is provided with discharging tube, it is characterized in that: described metering tank body is sealed shell of tank, its top also is provided with air inlet pipe and exhaust-valve, and described air inlet pipe connects source of the gas by air intake valve.
Described discharging tube is provided with tapping valve.
Described discharging tube has when arranging and exceeds the liquid level part of measuring in the metering tank body.
Adopt the beneficial effect of technique scheme: this mixing plant liquid meter adding set increases at the metering tank body air inlet pipe and exhaust-valve, air inlet valve position is in closed condition during the metering beginning, exhaust-valve is opened, and the feed liquor valve is opened, and liquid enters in the metering tank body through feed liquor valve, feed tube.Liquid by electronic scale weighing needs.The feed liquor valve cuts out when metering finishes, and exhaust-valve is closed, and INO, compressed air enter in the metering tank body of sealing, promotes liquid and discharges through the discharging tube of bottom, and intake valve cuts out afterwards.Described discharging tube is provided with tapping valve, tapping valve and intake valve are opened simultaneously, or tapping valve hysteresis intake valve a period of time open, the gases at high pressure that form in the metering tank body of sealing extrude the liquid of institute's weighing, more be conducive to spray evenly, and noresidue in the tank body realizes carrying fast, has saved the interpolation time.Adopt discharging tube to have when arranging and exceed institute's liquid level that measures structure partly in the metering tank body, tapping valve has been saved in the gravity flow of liquid when preventing from weighing, and has reduced cost.Compare with existing metering device, the utlity model has simple in structurely, cost is low, liquid conveying pressure height, characteristics such as speed is fast, and no liquid is residual in the tank body.
Description of drawings
Below in conjunction with accompanying drawing concrete enforcement of the present utility model is described in further detail.
Fig. 1 is structure principle chart of the present utility model.
Fig. 2 is the structure principle chart with tapping valve.
The specific embodiment
Mixing plant liquid meter adding set as shown in Figure 1, 2, by feed liquor valve 1, feed tube 2, air inlet pipe 3, intake valve 4, exhaust-valve 5, discharging tube 6, electronic scale 7 and metering tank body 8 are formed.Described metering tank body 8 is airtight tank structure, feed liquor valve 1, and feed tube 2, air inlet pipe 3, intake valve 4, exhaust-valve 5 are positioned at the top of metering tank body 8.Discharging tube 6 is positioned at metering tank body 8 bottoms, and described discharging tube 6 has when arranging and exceeds the liquid level part of measuring in the metering tank body, is provided with electronic scale 7 measuring tank body 8.Intake valve 4 is in closed condition during the metering beginning, and exhaust-valve 5 is opened, and feed liquor valve 1 is opened, and liquid is through feed liquor valve 1, and feed tube 2 enters in the metering tank body 8.Liquid by electronic scale 7 weighings needs.Feed liquor valve 1 cuts out when metering finishes, and exhaust-valve 5 is closed, and intake valve 4 is opened, and compressed air enters in the metering tank body, promotes liquid and discharges through the discharging tube 6 of metering tank body 8 bottoms, and intake valve 4 cuts out afterwards, finishes and once measures the interpolation process.As another kind of embodiment, described discharging tube 6 is provided with tapping valve 9, carries out discharge opeing under the situation of tapping valve 9 and intake valve 4 unlatchings.
