[0018] Preferably, the SV mixing unit is composed of multiple stacked baffles, and fixed grids are provided at both ends of the pipe, with the two ends of the pipe being the medium inlet and the mixing medium outlet, respectively.
[0019] By adopting the above structure and fixing the SV mixing unit inside the pipe in place by setting a fixed grid, the device is safer to use.
[0020] Compared with the prior art, this utility model has the following advantages:
[0021] 1. The present invention provides a support device below the pipe to improve the stability of the structure, and a shock-absorbing device is provided inside the support device to reduce the force between the pipe and the support device below during use, reduce noise during use, and extend the service life of the device.
[0022] 2. The device of this utility model is equipped with a shock absorption device, which is located between the pipe and the support base. The shock absorption device reduces the force of the pipe on the lower support device by the elastic force of the return spring, thereby extending the service life of the device.

[0029] like Figure 1-4 As shown, the premixer includes a connecting pipe 2 and a support device located below the connecting pipe 2. The connecting pipe 2 is cylindrical, with an SV mixing unit 3 housed in the central cavity. Connecting flanges 1 are located at both ends of the connecting pipe 2. The connecting pipe 2 is mounted on the support device, which includes a lower support base 7, support columns 8, and a bracket 10. Multiple support columns 8 are provided, forming a support on the support base 7. The connecting pipe 2 is placed on the support columns 8, and the bracket 10 is located below the support base 7. A vibration damping device 9 is installed between the connecting pipe 2 and the support base 7. The support device below the connecting pipe 2 improves the structural stability, and the vibration damping device 9 within the support device reduces the force between the connecting pipe 2 and the lower support device during use, reducing noise and extending the service life of the device.
[0030] Multiple shock-absorbing devices 9 are fixed to the support base 7 and located between the bottom of the connecting pipe 2 and the upper surface of the support base 7. The shock-absorbing device 9 includes a base 12, a sleeve 13, a return spring 14, and a pad 16. The base 12 is fixed to the support base 7, the support base 7 has the sleeve 13, the pad 16 is located at the bottom of the connecting pipe 2, and the return spring 14 is sleeved on the sleeve 13. A shock-absorbing pad 15 is connected to the bottom of the pad 16, and the top of the sleeve 13 is in contact with the bottom surface of the shock-absorbing pad 15. Support columns 8 are evenly distributed below the connecting pipe 2, and a buffer pad 17 is provided at the point where the top of the support column 8 contacts the connecting pipe 2. The device is equipped with shock-absorbing devices located between the connecting pipe and the support base. The spring force of the return spring reduces the force exerted by the connecting pipe on the lower support device, extending the service life of the device. The buffer pad 17 between the top of the support column 8 and the connecting pipe 2 reduces noise during use.
[0031] The bracket 10 is equipped with casters 11 at its bottom, and its top is hinged to the bottom of the support base 7. The bracket 10 can rotate and retract laterally towards the bottom of the support base 7. The SV mixing unit 3 is composed of multiple stacked baffles. Fixed grilles 6 are provided at both ends of the connecting pipe 2, which are the medium inlet 4 and the mixed medium outlet 5, respectively. The device bracket 10 can be retracted into the bottom of the support base 7, reducing the size of the support device and facilitating its transport. The fixed grilles 6 at the ends of the connecting pipe 2 fix the SV mixing unit 3 inside the connecting pipe 2 in place, making the device safer to use.
[0032] When using this device, first transport the support assembly to the operating mat and install it. Then, align and place the connecting pipe 2 on the support assembly, and securely connect the connecting flanges 1 at both ends of the connecting pipe 2 to the pipeline at the mixing point. The device is then ready for use. The device has a compact structure and is easy to operate. The support assembly improves structural stability, and the vibration damping device 9 inside the support assembly reduces the force between the connecting pipe 2 and the support assembly below during use, reducing noise and extending the device's service life.
