GB9845—88
This standard specifies the types and main parameters of vertical circular steel mechanical stirring vessels (referred to as stirring vessels) and their main parts. This standard applies to stirring vessels with a volume of 0.010~100m, a design pressure of -0.1~:12MPa gauge pressure, a liquid medium temperature of 10~~350, a dynamic viscosity of less than 500Pas, and a density of less than 2000kg/m. For stirring vessels with coatings or linings, this standard should also be referred to. This standard does not apply to stirring vessels without covers and directly fired. Reference standards

Note: Spherical room and flat cover mixing container are used for occasions where the inner weight of the cylinder is less than 1600mm and the design positive force is more than 2.5Ma. 4.550
3.2 The connection type between the upper cover and the cylinder is divided into two types: non-detachable and detachable. The inner diameter of the cylinder is less than or equal to 1200mm and it is advisable to use a detachable connection: 3.3 The volume of the mixing container refers to the sum of the volume of the cylinder and the bottom. The allowable deviation between the volume of the mixing container and the nominal volume is 0~+16% of the nominal volume value.
3.4 ​​The design pressure of the mixing container can refer to Appendix A (reference). Heat exchange type
4.1 The heat exchange type is divided into two types: external heat exchange and internal heat exchange. 4.2 External heat exchange generally adopts an integral jacket. According to needs, steel jackets, honeycomb jackets, semicircular pipe jackets, external coil jackets, etc. can also be used. 5 Stirring device
5.1 The stirring shaft can be inserted from the center of the top or bottom of the container, or it can be inserted away from the center of the container. 5.2 It is allowed to set two or more stirrers on one shaft. 5.3 The diameter of the stirring shaft shall comply with the provisions of ZBG92001. 8 Transmission device
6.1 The output shaft speed and rated power range of the transmission device shall comply with the provisions of Table 3. 6+2
The selection of motors shall comply with the provisions of GB49. Nominal volume, m

2When the axis speed is greater than 1 m/s or the temperature of the medium in the container is greater than 100°C, cooling measures should be taken for the packing seal. 7.2
7.3When the sealing chamber temperature of the mechanical seal is greater than 80°C, cooling measures should be taken. 7.4For flammable, explosive, toxic media or high vacuum occasions, double-end mechanical seals should be used. 7.5For flammable, explosive, highly toxic media with strong permeability or high vacuum occasions, other drive types without shaft seals can be used. 8
Discharge type
The discharge type is as follows. The lower pipe discharge or discharge valve discharge can be set according to the needs. Internal components
The internal components include baffles, guide tubes and coils, etc. The structural type can be set according to the needs. r/min
