Description
Technical field
The present invention relates to a kind of energy-saving high-precision hot-fluid scale.
Background technology
The hot-fluid scale is connected with fluid circuit, for detection of the flow of fluid.In the prior art, electronic flowmeter generally adopts powered battery, its principle of work is: after connecting the power supply in the electronic flowmeter, fluid in the fluid circuit is transported in the environment for use by electronic flowmeter, when the fluid in the fluid circuit during through electronic flowmeter, the flow that electronic flowmeter will meter fluid; When battery electric power deficiency or loss of power, electronic flowmeter will quit work, and fluid can not be transported in the environment for use yet, because the serviceable life of battery is limited, therefore, when electronic flowmeter uses for a long time, regularly replace, and is very inconvenient in operation.Flow in fluid circuit hour when the thrust that flow produces is less than or equal to friction force, though still have flow, can't be accomplished accurate measurement.
Summary of the invention
But the technical problem to be solved in the present invention provides a kind of self-powered, and flow is counted accurate hot-fluid scale.
For addressing the above problem, the present invention adopts following technical scheme: a kind of energy-saving high-precision hot-fluid scale, comprise the flow of hot water pipe, and be arranged on the table body of flow of hot water pipe one side, and be arranged on impeller and thermal conductance Blast Furnace Top Gas Recovery Turbine Unit (TRT) in the flow of hot water pipe pipe, and be arranged on the electronic measurement display device of table on the external side, and be installed in the dynamic power device of table in the body, be used for transforming the power that mobile current impeller rotation produces, be provided with energy conversion device in the described table body, described energy conversion device is connected with the thermal conductance Blast Furnace Top Gas Recovery Turbine Unit (TRT) with dynamic power device separately, be used for becoming electric energy in order to provide with thermal power transfer kinetic energy, described energy conversion device is connected with energy storage device respectively, described energy storage device is used for providing the power supply input to described electronic measurement display device, and described energy storage device is connected with control device in turn, electronic counter is connected with the electronic measurement display device.
Further, be provided with the signal switching device of the computing that matches with electronic counter in the described impeller, be used for the discharge that vane rotary produces is counted, and with the signal that produces to electronic counter.
Further, the water inlet in the described flow of hot water pipe is provided with a filter screen.
Further, described energy storage device is rechargeable battery, electric capacity or inductance.
The beneficial effect of energy-saving high-precision hot-fluid scale of the present invention is: be connected with measured flow of hot water pipe during use, its principle of work is: the flow in the flow of hot water pipe is after impeller and thermal conductance Blast Furnace Top Gas Recovery Turbine Unit (TRT), and dynamic power device and energy conversion device become electric energy with the kinetic transformation of fluid; The electric energy of energy conversion device output is shown body required electric energy is provided by energy storage device, by its control device institute's measurement of discharge information is presented in the electronic measurement display device again.Hence one can see that, the power supply of hot-fluid scale of the present invention is automatic acquisition, compared with prior art, the invention has the advantages that: the present invention adopts inactive component to measure discharge, the situation that battery deficiency or loss of power can not occur, do not need regularly the hot-fluid scale to be changed the maintenance of battery, and adopt signal transmission counting, effectively improved the degree of accuracy of Small flowrate measurement.
