Technical Field
[0001] The utility model relates to the technical field of pipeline micro flow control, in particular to a vertical micro precision flow sensing device. Background Technique
[0002] Due to the need for spray cooling during on-site titanium welding and grinding to prevent the titanium material from catching fire due to excessive temperature during the grinding process, which poses a safety hazard. When using a spray device on-site, it is necessary to add a water cut-off cycle to prevent the operator from dry grinding, which also poses a safety hazard. However, since the water flow used for spraying is small, the water flow detection devices on the market cannot effectively sense it, and a small flow water sensor needs to be newly developed. Content of the Utility Model
[0003] The purpose of the utility model is to provide a vertical micro precision flow sensing device to solve the problems raised in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] A vertical micro precision flow sensing device includes a flow sensing structure. The flow sensing structure is mounted on the front surface of the grinding device. The flow sensing structure includes a transparent water delivery pipe. A buoy moving groove is opened in the middle section of the inner wall of the transparent water delivery pipe. A colored buoy is slidably installed inside the buoy moving groove. A photoelectric sensor is sleeved on the middle section of the transparent water delivery pipe. One side of the photoelectric sensor is fixedly connected with a data transmission line. The grinding device includes an electric control box. A water tank is fixedly installed at the lower edge of the front surface of the electric control box. The other end of the data transmission line is connected to the electric control box. The lower end of the transparent water delivery pipe extends into the water tank and is connected to a water pump installed inside the water tank.
[0006] Furthermore: A grinding wheel frame is fixedly installed at the upper edge of one side of the front surface of the electric control box. A grinding wheel is rotatably installed inside the grinding wheel frame. A driving motor is fixedly installed at the upper edge of the front surface of the electric control box. The output end of the driving motor is fixedly connected to the grinding wheel.
[0007] Furthermore: The power supply system of the driving motor is connected to a foot-operated grinding wheel switch through a power transmission line installed inside the electric control box.
[0008] Furthermore: Spray heads are embedded and installed on the upper and lower surfaces of the grinding wheel frame.
[0009] Furthermore: An atomizer is fixedly installed at the upper end of the transparent water delivery pipe. One end at the upper side of the atomizer is fixedly communicated with a first delivery pipe. The other end at the upper side of the atomizer is fixedly communicated with a second delivery pipe. An air charging pipe is fixedly communicated with one side of the atomizer.
[0010] Furthermore, one end of the first conveying pipe is communicated with the spray head at the bottom of the grinding wheel frame.
[0011] Furthermore, one end of the second conveying pipe is communicated with the spray head at the top of the grinding wheel frame.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] Use a colored heat shrinkable tube with an outer diameter of 3 mm and a length of 10 mm. Heat one end to shrink it to a small bell mouth with a diameter of 1 mm to make a colored buoy 203. Place the heat shrinkable tube into a PU air pipe with an outer diameter of 6 mm and an inner diameter of 4 mm, with the shrunk end facing upwards. Make a "one" or "ten" shape with a 1 mm thick material and embed it into the upper and lower ends of the PU pipe with a suitable length to distinguish the upper and lower limit positions respectively. Finally, fix the PM-F45 / photoelectric sensor 204 with a slot width of 6 mm in the switch slot at the upper limit position. The overall flow sensing structure 2 must be installed vertically, pay attention to the upper limit facing upwards, and it is only useful for transparent liquids. Connect the brown wire of the DC24V photoelectric switch NPN to +24V, the black wire to 0V, and the white wire and the black wire are the output terminals. When water flows from bottom to top, the colored buoy is pushed upwards by the water flow to the upper limit position, which will block the ray of the photoelectric switch, and the photoelectric switch will send out a signal. When the water flows through, the buoy rises upwards to block the light source of the sensor, and then the sensor sends out a signal to start the grinding wheel to work. On the contrary, when there is no water flow, the grinding wheel cannot be started, filling the situation where the water circulation sensor is inaccurate in the small flow water state, reducing the safety hazard of spontaneous combustion during titanium material grinding.

The flow sensing structure 2 is mounted on the front surface of the grinding device 1. The flow sensing structure 2 includes a transparent water delivery pipe 201. A buoy moving groove 202 is formed in the middle section of the inner wall of the transparent water delivery pipe 201. A colored buoy 203 is slidably installed inside the buoy moving groove 202. A photoelectric sensor 204 is sleeved on the middle section of the transparent water delivery pipe 201; one side of the photoelectric sensor 204 is fixedly connected to a data transmission line 205, and the other end of the data transmission line 205 is connected to the electric control box 101.
[0021] Specifically, use a section of colored heat shrinkable tube with an outer diameter of 3mm * a length of 10mm, heat one end to shrink it to a small bell mouth with a diameter of 1mm to make the colored buoy 203; put the heat shrinkable tube into a PU air pipe with an outer diameter of 6mm * an inner diameter of 4mm, with the shrunk end facing up, and make it into a "one" or "ten" shape with a material thickness of 1mm, and embed it into the upper and lower ends of the PU pipe with a suitable length to distinguish the upper and lower limit positions respectively; finally, fix the PM-F45 / switch groove with a slot width of 6mm of the photoelectric sensor 204 at the upper limit position. The whole flow sensing structure 2 must be vertically installed, pay attention to the upper limit facing up, and it is only useful for transparent liquids. The NPN brown wire of the DC24V photoelectric switch is connected to +24V, the black wire is connected to 0V, and the white wire and the black wire are the output terminals.

When the water flows through, the buoy rises to block the light source of the sensor, and then the sensor sends out a signal to start the grinding wheel to work. On the contrary, when there is no water flow through, the grinding wheel cannot start, filling the situation where the water circulation sensor is inaccurate in the small flow water state, reducing the safety hazard of spontaneous combustion during titanium material grinding. The manufacturing process is simple, the cost is low, the installation is convenient, the maintenance is simple, and the induction is sensitive.
