Description

Technical Field

[0001] This utility model relates to the technical field of turbine vacuum pump units, and in particular to a gas-liquid separation turbine vacuum pump unit with a magnetic level gauge. Background Technology

[0002] Turbine vacuum pumps are a type of rotary vacuum pump used in vacuum systems in industries such as papermaking, chemical engineering, and metallurgy. Due to their advantages such as large suction capacity, high efficiency, no need for working fluid, and no corrosion or scaling, they are a replacement for volumetric vacuum equipment. In the production process of corrugated cardboard, vacuum adsorption systems play a crucial role.

[0003] A search revealed a novel turbo vacuum pump with publication number CN219452427U, comprising a suction pipe, a vacuum pump unit, an inlet pipe, an electric valve, and a control system. The vacuum pump unit consists of two sets, each with an inlet pipe connected to its inlet. The two sets of vacuum pump units are connected in parallel to the suction pipe via the inlet pipe. A magnetic levitation power system is installed at the rear end of each vacuum pump unit and connected to it. The electric gate valve is installed on the inlet pipe and connected to the control system. Using a magnetic levitation power system as the power unit for driving the vacuum pump unit eliminates energy loss due to mechanical friction. Through a dual-head design, coupled with corresponding switching controls and safety accessories, the unit can automatically switch between single and dual operation as needed, significantly improving the safety and stability of on-site production.

[0004] When the device in the disclosed patent is in use, it is easy to draw gas containing liquid into the turbine vacuum pump. Since the density and viscosity coefficient of liquid are much greater than those of gas, especially when the centrifugal impeller rotates at high speed, the force exerted by the liquid on the impeller is much greater than that exerted by the gas on the impeller, which can easily reduce the service life of the impeller and thus reduce the service life of the turbine vacuum pump. Utility Model Content

[0005] In response to the technical problem in existing patents that the device easily draws liquid-containing gas into the turbine vacuum pump during use, and that the liquid's density and viscosity coefficient are much greater than those of the gas, especially when the centrifugal impeller rotates at high speed, the force exerted by the liquid on the impeller is much greater than that of the gas, which easily reduces the impeller's service life and thus the service life of the turbine vacuum pump, this utility model provides a gas-liquid separation turbine vacuum pump unit with a magnetic level gauge.

[0006] The technical solution adopted in this utility model is: a gas-liquid separation turbine vacuum pump unit with a magnetic float level gauge, comprising: a suction pipe, multiple turbine vacuum pumps, an air inlet pipe corresponding to the turbine vacuum pump connected to the side of the suction pipe, an electric gate valve connected to the air inlet pipe, an air venting silencer connected to the air inlet pipe, an air filter mechanism connected to the side of the turbine vacuum pump, a gas-liquid separator connected between one end of the air filter mechanism and the air inlet pipe, and a magnetic float level gauge connected to the side of the gas-liquid separator.

[0007] Furthermore, an electric butterfly valve is connected to the venting silencer, and the electric gate valve is located between the suction pipe and the venting silencer.

[0008] Furthermore, the air filtration mechanism includes a filter box connected to the turbine vacuum pump and the gas-liquid separator, an arc-shaped filter screen located inside the filter box, a connecting pipe connected to the bottom of the filter box, a temporary storage box connected to the bottom of the connecting pipe, a slag discharge pipe connected to the bottom of the temporary storage box, and a sealing cover fixedly sleeved inside the slag discharge pipe.

[0009] Furthermore, both the filter box and the temporary storage box are cylindrical structures, and both ends of the arc-shaped filter screen are provided with connecting strips. The connecting strips are fixed to the inner wall of the filter box, and the outer diameter of the arc-shaped filter screen is smaller than the inner wall diameter of the filter box.

[0010] Furthermore, a first servo motor is provided on the side of the filter box, and a drive shaft is provided at one end of the output shaft of the first servo motor that extends into the filter box. Multiple scrapers are arranged in a circular array on the side of the drive shaft, and one side of the scraper is in contact with the inner side of the arc-shaped filter screen.

[0011] Furthermore, a dividing wheel is rotatably fitted inside the temporary storage box, and a second servo motor for driving the dividing wheel to rotate is provided on one side of the temporary storage box. The dividing wheel includes a rotating shaft rotatably fitted inside the temporary storage box and multiple dividing plates arranged in a circle on the side of the rotating shaft.

[0012] The beneficial effects of this utility model are: By setting up a gas-liquid separator, moisture in the gas can be easily separated, which reduces the impact of moisture on the service life of the turbine vacuum pump impeller and improves the service life of the impeller. Then, solid impurities in the gas are filtered through an arc-shaped filter screen, which reduces the wear of impurities on the impeller and further improves the service life of the impeller and the turbine vacuum pump. By installing a magnetic level gauge, it is easy to detect the liquid level in the gas-liquid separator. When there is too much water in the gas-liquid separator, the gas-liquid separator can be drained to reduce the probability that the water level in the gas-liquid separator is too high, which will affect the effect of the gas-liquid separator in separating moisture from the gas and affect the service life of the turbine vacuum pump. By setting up a scraper, the first servo motor can drive the transmission shaft to rotate the scraper, making it easy to quickly clean the arc-shaped filter screen. By setting the number of the dividing plates to be greater than four, the opening arc of the connection between the connecting pipe and the filter box to be less than 20 degrees, and the opening arc of the connection between the slag discharge pipe and the filter box to be less than 20 degrees, it is convenient to block air from being drawn back into the filter box through the slag discharge pipe by the dividing wheel, thus affecting the slag discharge of the slag discharge pipe. It is also convenient to open the slag discharge pipe to discharge slag when the turbine vacuum pump is working. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0018] To address the problems existing in the background art, this application proposes the following technical solution: A gas-liquid separation turbine vacuum pump unit with a magnetic level gauge includes: a suction pipe 1, multiple turbine vacuum pumps 2, an air inlet pipe 11 corresponding to the turbine vacuum pump 2 connected to the side of the suction pipe 1, an electric gate valve 12 connected to the air inlet pipe 11, an air venting silencer 13 connected to the air inlet pipe 11, an air filter mechanism 21 connected to the side of the turbine vacuum pump 2, a gas-liquid separator 22 connected between one end of the air filter mechanism 21 and the air inlet pipe 11, and a magnetic level gauge 23 connected to the side of the gas-liquid separator 22.

[0019] Furthermore, an electric butterfly valve 14 is connected to the venting silencer 13, and an electric gate valve 12 is located between the suction pipe 1 and the venting silencer 13.

[0020] Furthermore, the air filtration mechanism 21 includes a filter box 210 connected to the turbine vacuum pump 2 and the gas-liquid separator 22, an arc-shaped filter screen 211 located inside the filter box 210, a connecting pipe 212 connected to the bottom of the filter box 210, a temporary storage box 213 connected to the bottom of the connecting pipe 212, a slag discharge pipe 214 connected to the bottom of the temporary storage box 213, and a sealing cover 215 fixedly sleeved inside the slag discharge pipe 214.

[0021] Furthermore, both the filter box 210 and the temporary storage box 213 are cylindrical structures, and both ends of the arc-shaped filter screen 211 are provided with connecting strips 216. The connecting strips 216 are fixed on the inner wall of the filter box 210, and the outer diameter of the arc-shaped filter screen 211 is smaller than the inner wall diameter of the filter box 210.

[0022] Furthermore, a first servo motor 2101 is provided on the side of the filter box 210. The output shaft of the first servo motor 2101 extends into the filter box 210 and is provided with a drive shaft 2102 at one end. Multiple scrapers 2103 are arranged in a circular array on the side of the drive shaft 2102. One side of the scraper 2103 is in contact with the inner side of the arc-shaped filter screen 211.

[0023] Furthermore, a dividing wheel is rotatably fitted inside the temporary storage box 213. A second servo motor 2131 for driving the dividing wheel to rotate is provided on one side of the temporary storage box 213. The dividing wheel includes a rotating shaft 2132 rotatably fitted inside the temporary storage box 213 and multiple dividing plates 2133 arranged in a circular array on the side of the rotating shaft 2132. The number of dividing plates 2133 is greater than four. The opening arc at the connection between the connecting pipe 212 and the filter box 210 is less than 20 degrees. The opening arc at the connection between the slag discharge pipe 214 and the filter box 210 is less than 20 degrees. This facilitates the blocking of air from being drawn back into the filter box 210 through the slag discharge pipe 214, thus affecting the slag discharge of the slag discharge pipe 214. It also facilitates the opening of the slag discharge pipe 214 to discharge slag when the turbine vacuum pump 2 is working.

[0024] Working Principle: The turbine vacuum pump 2 is turned on, and the gas in the suction pipe 1 is discharged into the gas-liquid separator 22 through the inlet pipe 11. The gas-liquid separator 22 separates the moisture in the gas, reducing its impact on the impeller life of the turbine vacuum pump 2 and thus extending its service life. Then, solid impurities in the gas are filtered through the arc-shaped filter screen 211, reducing wear on the impeller and further extending its service life. A magnetic level gauge 23 is installed to monitor the liquid level in the gas-liquid separator 22. When there is too much water in the gas-liquid separator 22, it is turned on to drain the water, reducing the probability that an excessively high water level will affect the separation of moisture from the gas and thus the service life of the turbine vacuum pump 2. The first servo motor 2 is then turned on. 101 drives the drive shaft 2102 to rotate the scraper 2103, which facilitates quick cleaning of the arc-shaped filter screen 211. The impurities filtered out of the arc-shaped filter screen 211 are discharged into the dividing box 213 through the connecting pipe 212. The second servo motor 2131 drives the rotating shaft 2132 to rotate the dividing plate 2133, which facilitates the discharge of impurities in the dividing box 213 into the slag discharge pipe 214. When cleaning is required, the slag discharge pipe 214 is opened to discharge impurities, and the sealing cover 215 is opened to discharge the impurities. By setting the number of dividing plates 2133 to be greater than four, the opening arc of the connection between the connecting pipe 212 and the filter box 210 is less than 20 degrees, and the opening arc of the connection between the slag discharge pipe 214 and the filter box 210 is less than 20 degrees, it is convenient to block air from being drawn back into the filter box 210 through the dividing wheel and affecting the slag discharge pipe 214. It is also convenient to open the slag discharge pipe 214 to discharge slag when the turbine vacuum pump 2 is working.
