DETAILED DESCRIPTION

[0025] See also Figure 1-5 The present embodiment is a super strong self-spinning vortex anti-wax viscosity reducing oil enhancer, comprising a serially connected sonic wave device 1, a cavitation tube 2, and a vortex device 3, wherein the tail end of the vortex device 3 is connected with a self-spinning vortex atomizing device 4, wherein the self-spinning vortex atomizing device 4 comprises a vortex seat 41, wherein one end of the vortex seat 41 is provided with an oil inlet, and the center of the other end is provided with a rotating shaft 45, and both ends of the rotating shaft 45 are rotatably connected to the vortex seat 41 through thrust bearings 44, and a vortex nozzle 48 is fixedly provided at one end of the rotating shaft 45 facing the oil outlet, and a screw at one end of the rotating shaft 45 facing the oil outlet passes through the center of the vortex nozzle 48 and is connected to the oil outlet. A nut 46 is connected, and a stop washer 47 is installed between the nut 46 and the vortex nozzle 48; a plurality of spray holes 410 are provided on the vortex nozzle 48, and a plurality of flow holes 49 are provided in the swirl seat 41, and the flow holes 49 connect the oil inlet with the oil outlet, and the oil drives the vortex nozzle 48 to rotate when passing through the spray hole 410 of the vortex nozzle 48; a turbofan impeller 42 is fixedly installed at one end of the rotating shaft 45 facing the oil inlet; the turbofan impeller 42 includes a center block, and the center block is fixedly connected to the rotating shaft 45 by three hexagon socket countersunk screws 43, and a plurality of fan blades are evenly distributed along the circumference of the outer periphery of the center block.

[0026] There is a certain gap between the outer wall of the vortex nozzle 48 and the swirl seat 41. When the oil passes through the vortex nozzle 48, part of it passes through the spray hole 410 and part of it passes through the gap.

[0027] Furthermore, a certain angle is set between the spray hole 410 and the central axis to form a certain inclination, and the flow hole 49 also has a certain inclination and is aligned with the spray hole 410 .

[0028] Furthermore, the vortex nozzle 48 is provided with inclined surfaces on the inlet side corresponding to the spray hole 410, and these inclined surfaces enable the oil to generate radial thrust when pushed, thereby driving the vortex nozzle 48 to rotate.

[0029] Furthermore, the vortex device 3 comprises a shell, and six spiral flow channels 34 are evenly distributed on the inner wall of one end of the shell facing the oil outlet, and the lead of the spiral flow channels 34 is 300 mm.

[0030] Furthermore, a check ball 32 is installed at one end of the vortex device 3 facing the oil inlet, a valve port 33 cooperating with the check ball 32 is provided inside the vortex device 3, and a return spring 31 is installed on the other side of the check ball 32 relative to the valve port 33.

[0031] Furthermore, in order to prevent the vortex nozzle 48 from being damaged, a vortex cover 411 is installed at the oil outlet end of the vortex seat 41. The vortex cover 411 protects the vortex nozzle 48 and the rotating shaft 45. The vortex seat 41 and the vortex cover 411 are threadedly connected.

[0032] The working principle of the utility model is as follows: when pumping oil, the oil flows from the oil inlet to the oil outlet. When the oil passes through the check ball 32, the upward thrust is greater than the pressure of the return spring 31, thereby pushing the check ball 32 upward, and then continues to flow backward along the six spiral flow channels 34 of the vortex device 3. When entering the self-spinning vortex atomizing device 4, it first passes through the turbofan impeller 42. Under the driving force of the oil, the turbofan impeller 42 rotates, passes through the impeller, and then passes through the flow hole 49 to reach the vortex nozzle 48. The oil generates a rotational force by pushing the inclined surface of the vortex nozzle, thereby driving the vortex nozzle 48 to rotate. The rotation direction of the vortex nozzle 48 is the same as that of the turbofan impeller 42. Then most of the oil passes through the spray hole 410, and a part of the oil passes through the gap between the vortex nozzle 48 and the swirl seat 41 to be atomized. Under the rotation of the turbofan impeller 42 and the vortex nozzle 48, a double-stage series vortex drive is formed to break up the wax molecules in the oil, and the viscosity reduction and anti-wax effects are further improved; when the oil is pumped, the oil loses power. At this time, the reset spring 31 quickly bounces the check ball 32 back to its position, so that the check ball 32 closes the valve port 33, so that the oil above the check ball 32 cannot flow back, which greatly reduces the oil leakage caused by the slow return speed of the check ball 32, thereby improving the oil pumping efficiency.
