Agitator Stand
The agitator stand is an important support component in the drive system of a glass-lined reactor. By selecting the right agitator stand structure, you can achieve better agitator stability, more reliable shaft support, and easier maintenance under different operating conditions. Lante offers multiple agitator stand types to match different reactor sizes, sealing requirements, and maintenance preferences
The JBT type non-pivot agitator stand uses a threaded connection between the agitator shaft head and the stand. Because this structure does not include a pivot support point, the agitator tends to have a larger swing range during operation. The JBT type non-pivot agitator stand is commonly used for small glass-lined reactors of 1000l and below.
The DJ and LDJ single-pivot agitator stands are designed with a bearing box assembly in the middle of the stand. This structure helps support the weight of the agitator and control the radial swing of the shaft during operation. The agitator shaft head is connected to the reducer output end through a rigid coupling, which helps maintain stable agitator operation.
The DJ type agitator stand is used with a single mechanical seal, while the LDJ type agitator stand is used with a double mechanical seal. these single-pivot structures are suitable for glass-lined reactors below 12500l.
The SJ agitator stand and LSJ agitator stand use two bearing box assemblies in the middle of the stand to support the agitator weight and control radial movement more effectively. The shaft head is connected to the reducer output shaft through a rigid coupling, helping the SJ agitator stand and LSJ agitator stand provide more stable agitator running performance.
The SJ agitator stand is used with a single mechanical seal, while the LSJ agitator stand is used with a double mechanical seal. These double-support designs are suitable for glass-lined reactors of 12500l and above.
The four-column agitator stand is a customized stand structure and is available in both support-point and non-support-point versions. The four-column agitator stand features an open structure, making installation and maintenance more convenient. This design allows the mechanical seal to be replaced or serviced without removing the stand, reactor cover, reducer, or motor, which helps reduce maintenance cost.
The four-column agitator stand can use two different connection methods between the agitator shaft and the reducer:
Support-Point Four-Column Agitator StandThe agitator shaft is directly connected to the reducer through a rigid coupling, and the coupling is used to transmit torque.
Non-Support-Point Four-Column Agitator StandThe agitator shaft is connected to the reducer through a special extended coupling. Both ends of the coupling use a split structure, and the agitator shaft and reducer are tightened separately by pressure plates and bolts. In this arrangement, the gravity load, radial force, and axial force of the agitator are all carried by the reducer.
