Description
Technical field
The utility model belongs to instrument and meter for automation field of measuring technique, relates to a kind of level gauging cylinder continuously with online self-cleaning function.
Background technology
Smelter installs at the sidepiece of groove, tank the measurement that level gauging cylinder carries out liquid level in groove, tank usually.Because the fluid media (medium) in cell body or tank body is mostly containing many organic and inorganic impurities such as dust, mud, these impurity are easily attached on the tube wall of measuring cylinder, very easily cause fouling or the blocking of measuring cylinder pipeline, valve and measurement mechanism, as dredging and blowdown not in time, the accuracy of level gauging will be had a strong impact on.
The various universal measurement cylinders that current different manufacturers is produced, all exist can not continuously purge and cleaning impurity problem, after measurement dirty medium a period of time, all can occur measuring pipeline, primary sample mouth and valve blockage, detecting element is contaminated, now have to take the method for off-line to clear up to the device such as measuring cylinder and measurement instrument.Run into large-scale groove, tank when carrying out the cleaning work of level gauging cylinder production process must cut off medium and to go forward side by side the purging displacement of line pipe road, measurement mechanism, workload and labour intensity larger.Some production process another requires to meet continuous seepage, requires the long-term continuous coverage of level gauging and control, and therefore liquid level emasuring device requires to have continuously self-cleaning and dredging function.
Utility model content
The purpose of this utility model is for prior art Problems existing, and provide a kind of level gauging cylinder continuously with online self-cleaning function, this measuring cylinder can realize online automatically cleaning, and then can stable operation reliably and with long-term.
For this reason, the utility model adopts following technical scheme:
A kind of level gauging cylinder continuously with online self-cleaning function, comprise cylindrical shell, in described cylindrical shell, BL is installed, the top of described cylindrical shell is provided with communicating pipe, bottom is provided with lower communicating tube, the bottom of described cylindrical shell is also provided with blowing pipe, the tie point of described blowing pipe and cylindrical shell higher than or the tie point that flushes in lower communicating tube and cylindrical shell, described upper communicating pipe and lower communicating tube are connected with pressure measuring valve, described blowing pipe is connected with reverse checkvalve, and described lower communicating tube is arranged obliquely relative to cylindrical shell.
Further, the angle between described lower communicating tube and cylindrical shell is at 110-160 °.
Further, the caliber of described blowing pipe is less than the caliber of lower communicating tube.
Further, the bottom of described cylindrical shell is connected with blowoff valve.
The beneficial effects of the utility model are: can carry out automatically cleaning when not cutting off testing medium, and level gauging cylinder can be run by accurate stable for a long time, and cost of manufacture is low, and job operation is simple, be easy to realize.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1-cylindrical shell, 2-BL, 3-upper communicating pipe, 4-lower communicating tube, 5-blowing pipe, 6-pressure measuring valve, 7-reverse checkvalve, 8-blowoff valve, 9-tank body.
Embodiment
As shown in Figure 1, a kind of level gauging cylinder continuously with online self-cleaning function, comprise cylindrical shell 1, BL 2 is installed in cylindrical shell 1, the top of cylindrical shell 1 is provided with communicating pipe 3, bottom is provided with lower communicating tube 4, the bottom of cylindrical shell 1 is also provided with blowing pipe 5, the tie point of blowing pipe 5 and cylindrical shell 1 higher than or flush in the tie point of lower communicating tube 4 with cylindrical shell 1, upper communicating pipe 3 and lower communicating tube 4 were connected with pressure measuring valve 6, blowing pipe 5 is connected with reverse checkvalve 7, the bottom of cylindrical shell 1 is connected with blowoff valve 8, lower communicating tube 4 is arranged obliquely relative to cylindrical shell 1, and the angle between lower communicating tube 4 and cylindrical shell 1 is at 110-160 °, the caliber of blowing pipe 5 is less than the caliber of lower communicating tube 4.
During use, the upper communicating pipe 3 of the utility model level gauging cylinder was connected with cell body to be measured or tank body (for tank body) respectively with lower communicating tube 4, fluid media (medium) in tank body 9 enters in cylindrical shell 1 by upper communicating pipe 3 and lower communicating tube 4, and the BL 2 in cylindrical shell 1 can be measured in real time to the liquid level in tank body 9.Because lower communicating tube 4 is obliquely installed, when the liquid level in tank body 9 changes, fluid media (medium) in cylindrical shell 1 in tank body 9 by lower communicating tube 4 natural back flow, and then is formed cylindrical shell 1 and lower communicating tube 4 and washes away, and takes away part be attached to impurity on measuring cylinder barrel and tube wall by natural back flow.Also can open reverse checkvalve 7, the tube wall carrying out measuring cylinder by passing into outside flushing liquid in blowing pipe 5 cleans, and impurity stronger for adhesion can be cleaned.The caliber of blowing pipe 5 is less than the caliber of lower communicating tube 4, is conducive to the natural back flow of fluid media (medium).Blowoff valve 8 can be opened, by the discharge such as mud and impurity be deposited on bottom cylindrical shell 1 after a period of time.
