[0002] In the metallurgical industry, wet flue gas desulfurization (FGD) is one of the most widely used technologies. Limestone or lime slurry is used as the desulfurizer, and a desulfurization slurry agitator is installed on top of the storage container. A reduction motor drives the agitator, creating a suspension of limestone or lime particles with water. This ensures a uniform and stable composition of the desulfurization slurry, achieving efficient desulfurization. Due to factors such as the number of blades, slurry density, and rotational speed, the agitator encounters significant resistance during rotation. To overcome this resistance, a transmission device is required to transmit a greater torque.

[0003] The support device of the existing agitator is unreasonably designed. The agitator blade will vibrate vertically and deflect laterally due to unbalanced force during rotation, which can easily cause damage to connecting parts such as couplings, affecting the normal operation of the equipment and causing environmental accidents.

[0029] The utility model provides a transmission support device for a desulfurization slurry agitator. Compared with the prior art, the mounting plate 2 in the middle of the support sleeve 1 is provided with a mounting hole. The transmission body of the transmission mechanism 4 extends through the mounting hole and is connected to the mounting plate 2. The upper coupling 5 is connected to the output shaft of the reducer, and the lower coupling 13 is connected to the rotating shaft of the agitator. The support sleeve 1 can effectively support the transmission mechanism 4 and is respectively connected to the reducer and the agitator. The utility model can provide rigid support for the agitator, balance the forces on the agitator's paddles during rotation, prevent lateral deviation and swing, effectively control the vertical amplitude, reduce longitudinal vibration, and prevent environmental accidents.

[0030] An upper window is provided on the upper portion of the support sleeve 1. This window corresponds to the upper coupling 5, facilitating installation and maintenance of the upper coupling 5 and the output terminal of the reduction motor. A lower window is provided on the lower portion of the support sleeve 1. This window corresponds to the lower coupling 13, facilitating installation and maintenance of the lower coupling 13 and the agitator's rotating shaft. The upper and lower windows also reduce the weight of the support sleeve 1 without compromising its strength.

[0031] Connecting flanges are provided around the upper and lower ends of the support sleeve 1, securing the support sleeve 1 to the housings of the reduction motor and the agitator, thereby reducing relative vibration between the reduction motor and the agitator. The outer diameter of the support sleeve 1 increases from top to bottom, providing greater stability when the transmission mechanism 4 is mounted in a vertical position.

[0032] Preferably, the upper port of the support sleeve 1, the lower port of the support sleeve 1 and the mounting hole are coaxially arranged to ensure that the reduction motor, the support sleeve 1 and the agitator are coaxially arranged after installation, which can effectively reduce vibration.

[0033] A plurality of support ribs 3 are circumferentially arranged on the lower end surface of the mounting plate 2, and the plurality of support ribs 3 are all connected to the inner wall of the support sleeve 1. The support ribs 3 are respectively welded between the lower end surface of the mounting plate 2 and the inner wall of the support sleeve 1, which can improve the structural strength of the mounting plate 2, thereby improving the stability of the transmission mechanism 4.

[0034] See also Figure 2The transmission body includes a transmission housing and a transmission shaft 10. The transmission housing is inserted into the mounting hole and connected to the mounting plate 2; the transmission shaft 10 passes through the transmission housing and rotates with the transmission housing.
