Description

Technical Field

[0001] The utility model relates to the technical field of pulverizers, in particular to a sealed mechanical pulverizer. Background Art

[0002] The preparation of sodium rosinate usually involves a chemical reaction between rosin extracted from pine trees and alkaline substances (such as soda ash or caustic soda). The general steps for the preparation of sodium rosinate include rosin extraction, purification and oxidation treatment, saponification and drying. In the drying step, the dried product needs to be crushed to obtain powder of the required particle size, which requires a mechanical crusher. In order to avoid dust spilling and polluting the environment during crushing, the crusher usually has a certain sealing performance.

[0003] In the existing pulverizer, the plugging cover on the opening of the crushing container is generally provided with a plurality of locking and pressing mechanisms evenly arranged along the outer edge shape to ensure the compression and sealing performance. However, the plurality of locking and pressing mechanisms are independently arranged separately from each other, and there is often a lack of a mechanism that can transmit driving force for synchronous driving and tightening. As a result, when opening and closing the plugging cover, the plurality of locking and pressing mechanisms need to be tightened and loosened in turn, which is troublesome and inconvenient to operate and is not conducive to improving the opening and closing operation efficiency of the plugging cover.

[0007] A circle of Z-shaped stress-bearing plates is welded around the outer circle of the sealing cover;

[0008] A circle of swingably mounted push rods is arranged around the outer wall of the top opening of the tank body. The tail end of the push rod is rotatably connected to the head end of the connecting rod, and the head end swings downward to abut against the Z-shaped force plate.

[0009] Furthermore,

[0010] A circle of L-shaped force transmission rods is welded around the outer circle of the main body retaining ring, and a U-shaped force bearing frame is welded to the bottom of the main body retaining ring.
