The specific embodiment
Below will be described in further detail goal of the invention of the present invention, technical scheme and beneficial effect.
Be noted that following detailed description is all exemplary, is intended for the requested to provide further explanation of the invention.Unless otherwise, all technology used herein and scientific terminology have the identical meanings of usually understanding with the general technical staff of the technical field of the invention.
Fig. 2 shows a kind of specific embodiment of the water measurement device of concrete batch plant provided by the invention, comprises storage tank 1, cistern 2, the LOAD CELLS 3 of weighing for storage tank 1.The bottom of storage tank 1 is provided with the water yield and regulates mouth 6, and the water yield is regulated mouth 6 and is connected with drainpipe 7, on drainpipe 7, is provided with valve 8.
Storage tank 1 is suspended on by LOAD CELLS 3 on the hanger 10 of brace summer, and LOAD CELLS 3 changes the quality signal of storage tank 1 into measurable signal of telecommunication output, is sent to electric control system.Storage tank 1 is being brought into play the effect of water storage and water weighing hopper, its upper end is provided with water inlet 4, and lower end is provided with unloads the mouth of a river 5, unloads the mouth of a river 5 welding water pipe and ring flanges, ring flange is installed Pneumatic butterfly valve 11 by securing members such as bolt, packing ring, nuts, and butterfly valve 11 can be controlled the water yield of unloading of storage tank 1.
Valve 8 can be arranged on the position that the contiguous water yield is regulated mouth 6, and when the solenoid control valve 8 of electric control system was closed, the water yield that remains in drainpipe 7 can be controlled in less scope, reduces the water measurement error.
Preferably, the diameter that the water yield is regulated mouth 6 is 15%~25% of water inlet 4 diameters, keeps in this proportion, makes water yield adjusting mouthful 6 water yields that flow out less on the impact of moisture storage capacity 1, improve the metering precision of LOAD CELLS 3, guaranteed simultaneously the drainage efficiency of water yield adjusting mouth 6.
Preferably, the diameter of drainpipe 7 is regulated mouthfuls 6 diameter more than or equal to the water yield, can guarantee that like this current discharge swimmingly.
Fig. 3 shows the another kind of specific embodiment provided by the invention, and drainpipe 7 is connected with cistern 2, and the water of discharging from storage tank 1 can enter cistern 2 by drainpipe 7, thereby has realized recycling of water.
Fig. 4 shows in the another kind of specific embodiment provided by the invention, the water measurement device further comprises water storage bucket 9, and the return-flow structure that is arranged on drainpipe 7 upstream, this return-flow structure comprises the inverted-loop tube 14 of regulating mouthful 6 transverse tubes that are connected 13 and being connected and bending towards top with transverse tube 13 with the water yield.Up and be arranged on the water side below of inverted-loop tube 14, the discharge outlet of water storage bucket 9 is connected with drainpipe 7 water inlet openings of water storage bucket 9.Valve 8 is arranged on the vertical pipeline that inverted-loop tube 14 is connected with transverse tube 13 pipeline of storage tank 1 one sides (that is, near).From the water yield, regulate mouthful 6 water of discharging and fall into water storage bucket 9 by return-flow structure, then get rid of by drainpipe 7.Drainpipe 7 upstream (or inverted-loop tube) can be different from the diameter of downstream pipeline, and preferably, the diameter of downstream pipeline is greater than the diameter of upstream (or inverted-loop tube), to guarantee the smooth and easy of current.By the return-flow structure that arranges on drainpipe 7, remain in the water that the water in inverted-loop tube can follow in storage tank 1 and lay down together, improved the accuracy of water metering.
Below the concrete operation principle of setting forth the water system that Fig. 4 provides: during the concrete batch plant normal operation, water pump 12 provides power, and the water pump in cistern 2 is sent into to storage tank 1.This moment, the operated pneumatic valve 11 of storage tank 1 bottom was closed, and when storage tank 1 added water, LOAD CELLS 3 measured simultaneously.The water metering phase is divided into to thick title and smart title stage, to realize the high-precision measuring of water.Add the water initial stage, water flows into storage tank 1 fast.When the water weight that stores in storage tank 1 is a certain amount of over the target value of weighing, generally surpass 15%~25% of desired value, switch off the pump immediately 12, postpone the several seconds, when storage tank 1 is stablized, the weight of LOAD CELLS 3 weighing storage tanks 1, slightly the title stage completes.Then open the valve 8 on the drainpipe 7 that storage tank 1 lower end arranges, rely on the deadweight of water, water directly flows into water storage bucket 9 by drainpipe 7, the final cistern 2 that flows into, LOAD CELLS 3 employing subtraction principle meterings this moment, the continuous draining of storage tank 1, LOAD CELLS 3 measures simultaneously, when the weight that measures water in storage tank 1 when LOAD CELLS 3 was desired value, this moment is valve-off 8 immediately, and the smart title stage completes.Open the Pneumatic butterfly valve 11 that unloads 5 lower ends, the mouth of a river, to the concrete batch plant quantitative water supply.
The present invention adopts electric control system, realizes the automatic control of source of the gas supply, and source of the gas can be various ways, common is air compressor machine, and Roots blower etc., according to the signal of LOAD CELLS 3, closure or openness Pneumatic butterfly valve 11 and valve 8, realized automation and the control accuracy of water system.
The present invention also provides a kind of concrete batch plant (mixing plant) with this water measurement device, adopts this water measurement device accurately to supply water, and to guarantee the quality of products made thereby, meets the continuous pursuit of client to product quality.
As can be seen from the above description, the above embodiments of the present invention have realized following technique effect:
1, by the water yield is set on storage tank, regulate mouth, accurately control the water yield that storage tank is discharged;
2, the low discharge current due to water yield adjusting mouth are very little to the impact of storage tank, and the measuring accuracy of sensor improves greatly;
3, be different from the traditional water supply system, in metering process, do not need compensation of drop in elevation, shortened the water supply adjustment time;
4, the design of the return-flow structure on drainpipe, further improved the water supply accuracy;
5, by optimizing structure design, water storage is unloaded to the diameter proportion of the mouth of a river and water yield adjusting mouth and control within the specific limits, guaranteed precision adjusting needed least quantity of stage;
6, device provided by the invention is compared with existing water measurement device, and parts are less, are convenient to control, and are cost-saving.
