Description
Technical field
The invention belongs to the device of liquid in the Chinese medicine production industry or solid-liquid suspension on-line determination density and liquid level, the device of on-line determination soup density and liquid level in a kind of specifically Chinese medicine production run.
Background technology
Enrichment facility mainly adopts outer circulation concentrator, falling liquid film concentrator, knifing concentrator etc. in the existing Chinese medicine production run; Production run generally adopts relative density of medicine liquid to the striking point control of process parameters; Measure the mode that soup density generally adopts off-line; Therefore in concentration process, can not in time grasp the concentrating degree of soup, cause concentrate to criticize a quality instability, make product quality can not get guaranteeing.
?
Summary of the invention
The present invention provides the device of on-line determination soup density and liquid level in a kind of Chinese medicine production run, its objective is extract or concentrate are implemented online detection density and liquid level, for Process Automation of Traditional Chinese Medicines control provides information.
For reaching the technical scheme that the object of the invention adopts, the device of on-line determination soup density and liquid level in a kind of Chinese medicine production run, the technical scheme below adopting:
The device of on-line determination soup density and liquid level in a kind of Chinese medicine production run; The storage or the mensuration chamber of collection material are measured the top, chamber and are provided with material inlet, measure the chamber and connect B pressure difference transmitter and two pressure difference transmitters of A pressure difference transmitter; Wherein two of the A pressure difference transmitter pressure guiding pipe level altitude differences are connected in and measure the chamber; One pressure guiding pipe of B pressure difference transmitter connects measures the bottom, chamber, and another pressure guiding pipe of B pressure difference transmitter connects measures top of chamber, and the B pressure difference transmitter is connected with controller; Controller is connected with pump, and pump connects material outlet.
Further, two of said A pressure difference transmitter pressure guiding pipe differences in height are fixed as H
0, two pressure guiding pipe differences in height of B pressure difference transmitter are H
1, H
1>H
0Said mensuration chamber is stainless-steel tube or stainless steel tank body; Said pump is gear-type pump, ram pump, membrane pump, self-priming pump.
The pressure difference transmitter principle of work:
Pressure guiding pipe A pressure: Ρ
1=ρ gH
0+ P
0
Pressure guiding pipe B pressure: Ρ
2=ρ gH
1+ P
0
Pressure difference transmitter is measured pressure: Δ Ρ=Ρ
2-Ρ
1=ρ gH
1-ρ gH
0=ρ g (H
1-H
0)
In the formula:
P
0: the liquid level pressure
ρ: fluid to be measured density
G: local gravitational acceleration
H: transmitter drops into the degree of depth of liquid
Through the height of fixing two pressure guiding pipes, i.e. (H
1– H
0) be known, after recording pressure difference transmitter and measuring pressure Δ Ρ, can know the fluid to be measured density p through calculating; When fluid density is known,, can obtain liquid level through measuring pressure P.
Measuring the chamber among the present invention can be material pipe, extractor, storage tank, when being the concentrator discharge pipe as measuring the chamber, but the density of the present invention's on-line determination Chinese medicine concentrate; When the mensuration chamber is extractor, but the density and the liquid level of the present invention's on-line determination Chinese medicine extract; When the mensuration chamber is storage tank, but the present invention's on-line determination Chinese medicine density of liquid and liquid level.
