Detailed description of the invention
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Referring to Fig. 1 and Fig. 2, the preferred embodiment of a kind of measuring admixture of concrete mixing station bucket of the present invention shown in it gauge water flusher, the invention belongs to a kind of water feed proportioning system, comprise water pump and water transfer pipeline, mainly utilize water pump, through water distribution pipeline 1, water is delivered to water weighing hopper 11, allot the device of the water of specified wt; Above-mentioned additive metering bucket is to utilize LOAD CELLS to weigh the device of additive weight, be understood that to those skilled in the art, the LOAD CELLS using in the weight metering of the present invention in each fluid box can be the various LOAD CELLSs of selling on market.
Gauge water flusher of the present invention comprise be positioned at the water weighing hopper 11 of below, the crystal who is positioned at top claims water tank 3 and one end to be positioned at described crystal to claim water tank 3, the other end slightly to claim overflow pipe 2 with the water that described water weighing hopper 11 is connected, as shown in Figure 2, crystal wherein claims that water tank 3 is that weight for realizing the water of allotting more approaches the cisten mechanism that desired value arranges between the outlet of water transfer pipeline and water weighing hopper 11; The present invention also comprises by additive flushing line 6 and claims with described crystal the additive metering bucket 8 that water tank 3 is connected, described crystal claims to be provided with the additive flush box 4 being connected with described additive metering bucket 8 in water tank 3, and on described additive flush box 4, the height of end entrance (suitable for reading) slightly claims the height of end entrance on overflow pipe 2 (suitable for reading) lower than described water.Preferably, described crystal claims water tank 3 to be connected with water source with outside water pump by water distribution pipeline 1; Described additive metering bucket 8 is connected with additive pump by the additive pipeline 7 of preparing burden, and further, between described additive metering bucket 8 and described water weighing hopper 11, is connected by the additive butterfly valve 9 that feeds intake; Described crystal claims to claim butterfly valve 10 to be connected by crystal between water tank 3 and described water weighing hopper 11; Described additive flushing line 6 is provided with additive and rinses butterfly valve 5.
As mentioned above, the present invention is provided with the additive flush box 4 of constant volume in the original crystal of concrete mixing plant claims water tank 3, use the original water feed proportioning system of concrete mixing plant, and utilize water slightly claim overflow pipe 2 and additive flush box 4 separately the difference in height of entrance (water slightly claims overflow pipe 2 suitable for reading suitable for reading higher than additive flush box 4, as shown in Figure 2), realized the quantitative storage of wash water.
Particularly, operation principle of the present invention and the course of work are:
1, outside water pump and additive pump carry out the batching (now all states in closing of each butterfly valve in Fig. 2) of water and additive by water distribution pipeline 1 and additive batching pipeline 7.
2, water enters crystal by water distribution pipeline 1 and claims water tank 3, and crystal claims the water level in water tank 3 to raise gradually, and in the time that water level exceedes water and slightly claims overflow pipe 2 suitable for reading, water slightly claims overflow pipe 2 to enter water weighing hopper 11 by water to carry out water metering; Because water of the present invention slightly claims the suitable for reading suitable for reading higher than additive flush box 4 of overflow pipe 2, therefore slightly claim to be full of water in stage additive flush box 4 at water simultaneously.In the time that the water yield in water weighing hopper 11 reaches thick title value, water distribution pipeline 1 stops supplying water, and crystal claims butterfly valve 10 to open crystal to claim in water tank 3 water storing to flow into water weighing hopper 11 until the water yield reaches desired value; Now in additive flush box 4, be just full of water completely.
3, additive enters additive metering bucket 8 by the additive pipeline 7 of preparing burden, and reaches desired value additive batching pipeline 7 and stops for additive; After water batching, the additive butterfly valve 9 that feeds intake is opened additive is dropped into water weighing hopper 11, after completing, closes.
4, after additive feeds intake, additive rinses butterfly valve 5 and opens, whole water in additive flush box 4 enter additive metering bucket 8 by additive flushing line 6, the additive butterfly valve 9 that feeds intake is opened mixed liquor after flushing and is dropped into weighing hopper 11, after completing, close, the gauge water of realizing additive metering bucket rinses.
Be understood that for those skilled in the art, the water that rinses additive metering bucket due to the present invention has finally entered water weighing hopper 11, so the actual demand amount that the batching desired value of water is made as water by the control system of concrete mixing plant deducts the water yield that gauge water rinses.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characterictic is equal to replacement the specific embodiment of the present invention; And not departing from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope of request protection of the present invention.
