Description
Technical field
The utility model belongs to thick slurry conveying equipment technical field, is specifically related to a kind of hydrogen calcium that is applicable to and is the energy-conservation transport of centrifuge feed of centrifuge feed in producing.
Background technology
In hydrogen calcium production process, centrifuge is as the preferred unit of semi-finished product hydrogen calcium Separation of Solid and Liquid at present.An enterprise that produces 100000 tons hydrogen calcium per year need dispose about 35 desk centrifuges, if selecting power for use is 22KW, and 108m
3/ h, lift are the delivery pump that the centrifuge feed is given in the slush pump conduct of 21m, and a slush pump can be 7 ~ 10 desk centrifuge feed, and non-stop run in 24 hours.But centrifuge work has periodic characteristics, is generally 8 ~ 15 minutes according to one work period of material density, and centrifuge does not need continuous feeding thus.Therefore, in hydrogen calcium factory, often having a slush pump is being that 1 ~ 2 desk centrifuge is reinforced just, sometimes even do not have a desk centrifuge to feed in raw material, and causes slush pump idle running, has wasted a large amount of electric power resources, has increased the production cost of enterprise.Based on energy-saving and emission-reduction, reduce production costs, the purpose for enterprise and society create more wealth presses for the energy-saving centrifuge feeding system of exploitation.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of simple in structure, easy and simple to handle, is specially adapted to the energy-conservation transport of centrifuge feed into the production application of hydrogen calcium.
The purpose of the utility model is achieved in that and comprises slush pump, converter plant, pressure sensor device and conveying pipeline that the motor of described slush pump and converter plant electrically connect, converter plant and pressure sensor device electric connection; The conveying pipeline of slush pump connects the centrifuge charging aperture.
The utility model adopts converter technique; Immediately change according to pressure in the carrier pipe and judge that slush pump is in the feed state, still be in non-feed state, and immediately the slush pump motor be adjusted to suitable working speed; Reduce the energy consumption under the no centrifuge duty, reach energy-conservation purpose.
Description of drawings
Fig. 1 is that the overall structure of the utility model concerns sketch map;
Among the figure: 1-pressure sensor device, 2-converter plant, 3-slush pump, 4-conveying pipeline, 5-electric control line; QF1 among the figure is the power switch of converter plant.
Specific embodiments:
Below in conjunction with accompanying drawing and embodiment the utility model is further described, but never in any form the utility model is limited,, all fall into the protection domain of the utility model based on any conversion that the utility model training centre is done.
As shown in Figure 1, the utility model comprises slush pump 3, converter plant 2, pressure sensor device 1 and conveying pipeline 4, and the motor of described slush pump 3 and converter plant 2 electrically connect, and converter plant 2 electrically connects with pressure sensor device 1; The conveying pipeline 4 of slush pump 3 connects the centrifuge charging aperture.
Described pressure sensor device 1 is arranged on the conveying pipeline 4 of slush pump 3 outlets, and the signal of pressure sensor device 1 is delivered in the converter plant 2 through electric control line 5.
The motor of described converter plant 2 and two groups of above slush pumps 3 electrically connects.
Described converter plant 2 and two above pressure sensor devices 1 electrically connect.
Described pressure sensor device 1 is electrohydraulic pressure control table or pressure sensor.
The utility model operation principle:
The utility model adopts converter plant 2 to cooperate pressure sensor device 1; Pressure signal changes in the conveying pipeline 4 that converter plant 2 collects according to pressure sensor device 1; The rotating speed of converter plant 2 adjustment slush pump motors 3; Realization is to the regulation and control of the feed state of slush pump 3, and the suitable pressure of centrifuge feed is given in maintenance.When having many desk centrifuges to need feed, conveying pipeline 4 internal pressures can reduce, 2 variations of converter plant according to this pressure signal, and the 3 motor accelerated services of adjustment slush pump are to guarantee having normal defeated material pressure.Converter plant 2 is not adjusted to the reduction of speed pressure constant state with slush pump 3 motors when having centrifuge to need charging, to reduce energy loss.
The course of work of the utility model is described with an embodiment below:
The present embodiment configuration: pressure sensor device 1 is a YTZ-150 type resistance-type teletransmission Pressure gauge, and its range is 0 ~ 0.6MPa; Slush pump 3 is 80NJL, 22KW, 108m
3/ h, lift are 21m; The slush pump motor adopts Y180L-4/22KW; Converter plant 2 is a HLP 30KW frequency converter.It is three desk centrifuges feed simultaneously simultaneously that slush pump 3 is set.
Start power switch QF1, make frequency converter in running order, the leading-out terminal of frequency converter connects slush pump 3 motors, and resistance-type teletransmission Pressure gauge is arranged on the conveying pipeline 4 of slush pump 3, and electrically connects through electric control line 5 with frequency converter.Through test, when not having centrifuge to feed in raw material, the outlet pressure of slush pump 3 is 0.12MPa, and when three desk centrifuges need feed in raw material simultaneously, pressure was then reduced to 0.08MPa, so the constant voltage value of frequency converter is set at 0.08MPa.
Effect comparison with prior art:
