The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
In the description of the present invention, unless otherwise specifically limited, installation and connection terms should be construed broadly, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in consideration of the technical details.
Referring to fig. 1 and 2, the negative pressure dust removing system according to the embodiment of the utility model includes a dust removing system 100 and a monitoring system 200, the dust removing system 100 includes a dust remover 110, a vacuum pipeline 120 and a vacuum gauge 130, and the vacuum gauge 130 is communicated with the vacuum pipeline 120; the monitoring system 200 includes a pressure module 210 and a PLC220, the pressure module 210 being electrically connected to the vacuum gauge 130 and the PLC220, respectively.
For example, the dust remover 110 absorbs dust or other substances generated in the lithium battery production process through the vacuum pipeline 120 to further perform negative pressure dust removal on the lithium battery; the monitoring system 200 is located in the dust remover 110, the vacuum pipeline 120 is used for sucking dust or other substances into the dust remover 110, the vacuum gauge 130 is used for collecting the air pressure of the vacuum pipeline 120, and the pressure module 210 is used for transmitting a pressure data signal transmitted by the vacuum gauge 130 to the PLC 220; the role of the PLC 220: the pressure data collected from the pressure module 210 by the vacuum gauge 130 is converted into wind speed according to the relation between the wind speed and the wind pressure, and is monitored according to the requirements of customers, so that the function of alarming when the pressure data exceeds the control range is realized.
If the welding procedure in the industry requires that the wind speed of the vacuum pipeline 120 is more than or equal to 15 m/s; according to the relation between the wind speed and the wind pressure, the following conditions are known: wp ═ v215X15/1600 0.1401625kN/m2 is 140.6Pa, namely, the requirement is that the ambient pressure-the pressure in the pipe is more than or equal to 140.6 Pa.
The relation between wind speed and wind pressure is as follows:
dynamic pressure of wind wp ═ 0.5 ro · v2(1)
Wherein wp is wind pressure [ kN/m2], ro is air density [ kg/m3], and v is wind speed [ m/s ].
The relationship between the air density (ro) and the gravity (r) is r-ro-g, and hence ro is r/g. Using this relationship in (1), we obtain:
wp＝0.5·r ·v2/g (2)
this formula is a standard wind pressure formula.
Under standard conditions (pressure 1013hPa, temperature 15 ℃), air weight r is 0.01225[ kN/m3 ]. The acceleration of gravity g at 45 ° latitude is 9.8[ m/s2], we get:
wp＝v2/1600 (3)
this equation is a general equation for estimating wind pressure using wind speed. As a complex complete system, the performance of the dust extraction system 100 is typically assessed by a number of parameters, the parameters for assessing the dust extraction system 100 are as follows:
air volume: the gas volume (m3/h) of a certain section of the gas flow pipeline passing through the dust removal system 100 in unit time;
wind speed: the flow speed (m/s) of airflow in an airflow pipeline of the dust collection system is indicated;
wind pressure: the pressure difference between the interior of the gas flow duct and the external environment is expressed in Pa or mm water. The three parameters of the air volume, the air speed and the air pressure are mutually connected and restricted in a dust removal system 100.
