Side into the mixer is a stirring device is mounted on the side wall of the cylinder device, the agitator mixer on the generally axial flow type, with a multi-propeller agitator, under the same power consumption, the maximum stirring effect can be obtained power consumption is only the top of stir 1/3 to 2/3, the cost is only the top of stir 1/4 to 1/3. Speed ??can be 200 ~ 750r / min. Widely used in desulfurization, denitrification and a variety of large-scale stirred tank or tank removal. In particular, the use of one or more side-mixer in a large tank or storage tank to work together, in the case of low power consumption they can get a good mixing effect. Mounted on a variety of refinery and depot tank base side entering agitator used for asphalt, residual oil, crude oil, fuel oil, diesel oil and stirred, to reconcile, heat transfer, homogenization and to prevent precipitation of the effect . Front and rear axles at Erdao mechanical seal, ensuring no leakage medium tank.
