Description

Technical Field

[0001] The utility model relates to the technical field of disc-type separator feeding, in particular to a disc-type separator. Background Art

[0002] Disc separator is a high-speed sedimentation centrifuge. It can quickly and effectively separate liquids from solids, or mixtures of two immiscible liquids and solids, by using high speed and strong centrifugal force. Due to its high separation efficiency, it is widely used in industries such as shipping, food, medicine, chemical industry, textile and environmental protection.

[0003] The disc separator is mainly composed of motor, vertical shaft system, drum, frame, inlet and outlet devices, etc. (such as Figure 1 (as shown). The drum is the core component of the separator, where materials rotate at high speed for separation. The inlet and outlet mechanism is where materials enter and exit the drum. Material enters through a feed pipe inserted into the drum, is distributed by a distributor, and is separated between the discs. After separation, the clear liquid is pumped through a centrifugal pump and a clear liquid outlet pipe to a clear liquid tank. Solids are discharged through the gaps and removed from the drum by a centrifuge. They enter the flow channel of the frame and exit the separator through the discharge channel.

[0004] When separating some special materials, such as beer, milk and other materials that are prone to foaming, when the materials enter the separator through the feed pipe, they are suddenly subjected to the shear force generated by the high-speed rotation (6000-10000RPM), which will produce a large amount of foam. Due to the surface tension, these foams will carry a large amount of fine particles of solids, which will directly flip the material from the center of the distributor. Without being separated between the discs, they will directly enter the clear liquid centripetal pump chamber and be transported to the clear liquid tank through the clear liquid outlet pipeline by the centripetal pump. A large amount of fine particles of solids are not separated, resulting in poor separation effect and low solid removal rate. Therefore, a feed pipe that can effectively prevent foam from flipping is needed. This patent designs a disc separator feed sealing device suitable for separating materials that are prone to foaming, such as beer and milk. Utility Model Content

[0011] Furthermore, the diameter of the sealing gasket is larger than the diameter of the annular folded edge.
