Further, positioning element is arranged on the backstay of scale hooper top, through inserting the pilot hole performance positioning action of scale hooper top cover.
Further, the mouth of a river of unloading of scale hooper links to each other with stirring host through flexible pipe.
The length of the transverse water inlet pipe that links to each other with the water inlet of scale hooper further, is smaller or equal to 800mm.
Further, this scale hooper is cylindrical, and the lower end has the taper water collecting part.
Another object of the present invention is to provide a kind of concrete batch plant, comprise above-mentioned water measurement device.
Through water measurement device provided by the invention and concrete batch plant; Realized following advantage: traditional thick, smart weighing mode of claiming is given up in (1); Only with a set of tubes pump water inlet device and a tension load cell; Simple in structure, can satisfy flow and precision that the mixing plant metering is intake, reduced cost again; (2) adopt cylindrical scale hooper, processing and fabricating is simple, can produce in batches at an easy rate; (3) in the buffer part of water delivering orifice design, can reduce the impact of scale hooper and the formation of eddy current; (4) anti-eddy current block piece is set in the scale hooper and can prevents that the sealing turn forms eddy current; (5) the unique flexible pipe of positioning element and bottom that is used to locate scale hooper is connected the stability that can keep scale hooper, makes the measuring accuracy height; (6) compare with traditional thick smart title, it also has flow process characteristics few, simple to operate.
Description of drawings
The accompanying drawing that constitutes the application's a part is used to provide further understanding of the present invention, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
Fig. 1 shows the structural representation of concrete batch plant provided by the invention with the water measurement device;
Fig. 2 shows the elevational schematic view of the buffer part of water measurement device employing provided by the invention.
Embodiment
To do further detailed explanation to goal of the invention of the present invention, technical scheme and beneficial effect below.
Be noted that following detailed description all is exemplary, being intended to provides further explanation to desired the present invention.Unless otherwise, all technology used of this paper and scientific terminology have with the present invention under the identical meanings of those of ordinary skill common sense of technical field.
Fig. 1 shows the structural representation of concrete batch plant provided by the invention with the water measurement device; This water measurement device comprises scale hooper 1 and LOAD CELLS 2; The upper end of scale hooper 1 is provided with water inlet; Its bottom is provided with unloads the mouth of a river, and scale hooper 1 is designed to cylindrical, and the bottom has the taper water collecting part.This water measurement device further comprises the buffer part 3 that is connected with the water inlet of scale hooper 1.LOAD CELLS 2 can be a kind of tension load cell, scale hooper 1 is suspended on the support bar water yield in the weighing balance batch box 1 through LOAD CELLS 2.
Preferably, buffer part 3 provided by the present invention can be a umbrella shower nozzle 6, and the water that water inlet is flowed out forms the umbrella current, reduces the impact to scale hooper 1.Fig. 2 shows the elevational schematic view of the embodiment of a kind of buffer part 3 provided by the invention; Preferably; Netted barrier plate 7 is set in umbrella shower nozzle 6, and 7 pairs of current of netted barrier plate are shunted, and form the umbrella current through umbrella shower nozzle 6 then; Further reduced the impulsive force of current, also avoided simultaneously because the formed eddy current of a large amount of fast water inlets to scale hooper 1.But it is understandable that all can be used for alleviating the parts of water flow impact pressure can be as the buffer part 3 of water measurement device of the present invention.
Water measurement device provided by the invention further comprises the anti-eddy current block piece that is arranged in scale hooper 1 cavity, and as shown in Figure 1, this anti-eddy current block piece can be a dividing plate 4.Dividing plate 4 can radially be distributed in the bottom of scale hooper 1.Setting through dividing plate 4; The formed eddy current of current in the time of can avoiding into water and unload water, and, because current easily scale hooper 1 unload the mouth of a river around form eddy current; So as preferred embodiment; Dividing plate 4 is a triangle, and an one of which side extends upward along the sidewall of scale hooper 1, and extend the bottom of opposite side edge scale hooper 1.Dividing plate 4 plays barrier effect at the end near scale hooper 1 sidewall to current, prevents to form eddy current; Near scale hooper 1 unload the mouth of a river one end, less to the barrier effect of current, be convenient to water and discharge from unloading the mouth of a river.
As shown in Figure 1; Water measurement device provided by the invention further comprises the positioning element 5 that is used to locate scale hooper 1; Positioning element 5 can be arranged on backstay anti-on the scale hooper 1; One end of backstay is connected with fixed object, and the other end is fixed on the upper surface of scale hooper 1, perhaps inserts in the pilot hole of scale hooper 1 top cover.Through positioning element 5 is set, can prevent effectively that scale hooper 1 from axial direction moving.It is understandable that positioning element 5 can also be location-plate or locating support, positioning element 5 also can be arranged on the diametric(al) of scale hooper 1, prevents moving along diametric(al) of scale hooper 1.
Preferably, the mouth of a river of unloading of scale hooper 1 links to each other with stirring host through flexible pipe 8, further controls the axial wobble of scale hooper 1.
Preferably, the length of the transverse water inlet pipe 9 that links to each other with the water inlet of scale hooper 1 is smaller or equal to 800mm, intake pump is stopped after, the water yield that falls into scale hooper 1 is less, stabilization time is short.
The present invention also provides a kind of concrete batch plant with this water measurement device, adopts this water measurement device not only can accurately supply water, and required water inlet and to unload the water time shorter, and structure is also fairly simple, is convenient to operation.
From above description, can find out that technical scheme provided by the invention has realized following technique effect:
(1) give up traditional thick, smart weighing mode of claiming, simple in structure only with a set of tubes pump water inlet device and a pull-type sensor, can satisfy flow and precision that mixing plant measures water inlet, reduced cost again;
(2) adopt cylindrical title bucket, processing and fabricating is simple, can produce in batches easily;
(3) specially designed buffer part can reduce the impact of scale hooper and the formation of eddy current;
(4) anti-eddy current block piece is set in the scale hooper and can prevents that the sealing turn forms eddy current;
(5) positioning element is connected the stability that can keep scale hooper with the bottom flexible pipe, makes measuring accuracy high;
(6) compare with traditional thick smart title, it also has flow process characteristics few, simple to operate.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
