The operators can be combined together through the straight-through cutting sleeve type steel pipe joint, the steel pipe, the right-angle cutting sleeve type joint, the three-way cutting sleeve type joint and the four-way cutting sleeve type joint, and can also be connected together through the welded steel pipe structure, and the final purpose is to respectively provide spray water (warm water) for the first cleaning nozzle 100, the second cleaning nozzle 200 and the third cleaning nozzle 300 which are positioned at different positions through one water supply port, and a total control valve is arranged at the water supply port to control the switch of the spray water.

The first adapter 400 is provided such that the first cleaning nozzle 100 can be assembled with the first adapter 400 into a nozzle assembly having external threads, and the nozzle assembly can be directly screwed into and fixed to the current collector 10 from the outside, thereby improving the working efficiency of installation, repair, maintenance, and cleaning.
Further, in the present embodiment, the other end of the first adapter 400 is provided with an internal thread m430; the device for cleaning the alumina scab also comprises a cutting sleeve type joint, wherein the cutting sleeve type joint is provided with an external thread n440; the internal thread m430 is adapted to the external thread n440, so that the first adaptor 400 is advantageously connected to other pipes by a ferrule type adaptor, and the connection between the plurality of first cleaning nozzles 100 is achieved. Since the first adapter 400, the second adapter and the third adapter are identical in structure, detailed structures of the second adapter and the third adapter are not described in detail herein.
Alternatively, in the present embodiment, the end surface of the first cleaning nozzle 100 is lower than the inner surface of the current collector 10, the end surface of the second cleaning nozzle 200 is lower than the inner surface of the current collector 10, and the end surface of the third cleaning nozzle 300 is lower than the inner surface of the volute 30, which is advantageous in that the first cleaning nozzle 100, the second cleaning nozzle 200, and the third cleaning nozzle 300 do not interfere with the rotating impeller 20, nor block the flow of gas. Furthermore, the end face of the first cleaning nozzle 100 cannot be lowered too much below the inner surface of the current collector 10, thereby avoiding affecting the formation of the fan-shaped nozzle face of the first cleaning nozzle 100. In the present embodiment, the installation depth of the nozzle assembly is controlled by controlling the position of the start end surface of the internal thread c11 formed on the current collector 10 or the scroll case 30 so as to achieve a preset installation depth.
Illustratively, the distance of the end face of the first cleaning nozzle 100 below the inner surface of the current collector 10 is set to 1mm to 2mm, the distance of the end face of the second cleaning nozzle 200 below the inner surface of the current collector 10 is set to 1mm to 2mm, and the distance of the end face of the third cleaning nozzle 300 below the inner surface of the scroll case 30 is set to 1mm to 2mm.
As shown in fig. 5 to 6, the present embodiment also provides a turbine vacuum pump cleaning system, which mainly includes a water tank 600, a water pump 500, and the above-mentioned alumina scarring cleaning device, one end of the water pump 500 is communicated with the water tank 600, and the other end of the water pump 500 is communicated with one of a first connection pipe or a second connection pipe in the alumina scarring cleaning device. The water tank 600 contains warm water, and the water tank 600 can supply warm water to the water pump 500.
Further, the turbine vacuum pump cleaning system further includes a controller 700, a cleaning valve 800, and a drain valve 900, the cleaning valve 800 being disposed between the means for cleaning alumina scarring and the water pump 500, the drain valve 900 being in communication with a drain of the means for cleaning alumina scarring. The controller 700 is electrically connected to the water pump 500, the purge valve 800, the turbine vacuum pump 1000 in the apparatus for cleaning alumina scarring, and the drain valve 900.
Alternatively, the controller 700 is a PLC controller commonly found in the market.
A schematic of the working flow of the turbine vacuum pump cleaning system is shown in fig. 6. Specifically, when the controller 700 detects that the operation time of the turbine vacuum pump 1000 reaches the set cleaning time, the controller 700 decreases the rotational speed of the turbine vacuum pump 1000 to the preset cleaning rotational speed, and when the controller 700 detects that the rotational speed reaches the preset cleaning rotational speed, the controller 700 starts the water pump 500 to perform online spray cleaning on the alumina scar in the turbine vacuum pump 1000 through the first cleaning nozzle 100, the second cleaning nozzle 200 and the third cleaning nozzle 300, wherein the cleaning time period is a preset value. When the cleaning time is up, the controller 700 turns off the water pump 500 first, and after the controller 700 detects that the water pump 500 stops running, the controller 700 controls the turbine vacuum pump 1000 to resume the normal running mode for normal process use.
Specifically, the cleaning interval time, the cleaning duration time and the cleaning rotational speed are set in the PLC controller. When the PLC system detects that the purge time has been reached, the system triggers a purge mode. When the anti-surge valve is fully opened and other system pipelines are fully closed, after detecting that the valve opening is 100%, the PLC controls the frequency converter to set the rotating speed of the turbine vacuum pump 1000 to the cleaning rotating speed, and detects whether the feedback rotating speed reaches the preset cleaning rotating speed:
when the detected feedback rotation speed reaches the preset washing rotation speed, the water pump 500 is started, the washing valve 800 and the drain valve 900 of the volute 30 after the water pump 500 is opened, the PLC starts timing, and when the timing time reaches the washing duration, the water pump 500, the washing valve 800 and the drain valve 900 are closed. Then, the system resumes the operation mode, the anti-surge valve is opened and closed according to the anti-surge logic, and the rotation speed of the turbine vacuum pump 1000 is operated according to the normal operation rotation speed set by the PLC.
When the detected feedback rotation speed does not reach the preset cleaning rotation speed, if the vacuum degree in the turbine vacuum pump 1000 is smaller than the preset vacuum degree, the PLC controller starts a current control rotation speed mode, so that the rotation speed of the turbine vacuum pump 1000 starts to rise, after the output current of the frequency converter reaches the rated current of the motor, whether the feedback rotation speed reaches the preset cleaning rotation speed is detected again, and the circulation is sequentially performed until the detected feedback rotation speed reaches the preset cleaning rotation speed.
It is to be understood that the foregoing is only illustrative of the presently preferred embodiments of the invention and the technical principles that have been developed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, while the invention has been described in connection with the above embodiments, the invention is not limited to the embodiments, but may be embodied in many other equivalent forms without departing from the spirit or scope of the invention, which is set forth in the following claims.
