Description

Technical Field

[0001] The invention belongs to the technical field of separation equipment, and particularly relates to a steam seal mechanism of a disc separator. Background Art

[0002] During the separation process of a disc separator, according to the characteristics of the material, it is generally liquid-solid two-phase separation and liquid-liquid-solid three-phase separation. The material enters the separation area of the separator through the feed pipe for separation, and the separated clear liquid and slag phase are discharged out of the separator through the light (heavy) phase clear liquid outlet and the slag phase outlet respectively.

[0003] A disc separator is a high-speed rotating separation device. During normal operation, part of the energy is lost and converted into heat, causing some components of the separator and the air flow to heat up. In addition, in order to achieve a better separation effect for some materials, the material will be heated to a certain separation temperature by a heating device before entering the separator. These factors cause the liquid material entering the separator and the moisture in the air to vaporize to a certain extent. If these liquid vapors enter the separated clear liquid chamber and mix with the clear liquid, the clear liquid will become turbid, thereby reducing the separation effect. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a steam seal mechanism for a disc separator. The material enters the feed chamber through the feed pipe, and then enters the separation area of the separator for separation. The separated clear liquid enters the clear liquid chamber and is pumped out of the separator by a centripetal pump. A steam seal joint effectively prevents various vapors in the feed chamber from entering the clear liquid chamber between the feed chamber and the clear liquid chamber, so that the clear liquid becomes turbid, thereby better ensuring the quality of the separated clear liquid.

[0005] The present invention provides a steam seal mechanism for a disc separator, which includes a feed pipe (7). A distributor (6), a steam seal joint (5), a centripetal pump (2) and a pump chamber cover (1) are sleeved and installed on the circumference of the feed pipe (7). The lower end of the feed pipe (7) faces the vertical shaft nut (8) connected to the drum body (9). The feed chamber (10) is formed by the feed pipe (7), the steam seal joint (5), the distributor (6), the drum body (9) and the vertical shaft nut (8), and the clear liquid chamber (15) is composed of the centripetal pump (2), the pump chamber cover (1), the drum cover (4), the distributor (6), the steam seal joint (5) and the feed pipe (7); the steam seal joint (5) is located between the feed chamber (10) and the clear liquid chamber (15); the steam seal joint (5) and the distributor (6) are positioned and connected by a positioning pin (3).

[0006] As a further technical solution of the present invention, the steam seal joint (5) surrounds the outside of the circumference of the feed pipe (7).

[0007] Further, two sealing grooves are provided at the joint between the gland joint (5) and the distributor, and a first sealing ring (11) and a second sealing ring (12) are respectively installed in the grooves.

[0008] Further, a plurality of ribs are provided at the lower feed chamber (10) of the gland joint (5); a plurality of ribs are provided at the upper clear liquid chamber (15) of the gland joint (5).

[0009] Further, a circular ring is provided at the upper part of the gland joint (5) where it mates with the drum cover (4), and a sealing groove is provided and a third sealing ring (13) is installed.

[0010] Further, a sealing groove is provided at the joint between the drum cover (4) and the pump chamber cover (1), and a fourth sealing ring (14) is installed.

[0011] The advantages of the present invention are that through the gland mechanism of this disc separator, various vapors generated in the feed chamber due to heat energy loss and material heating during the separation process can be effectively prevented from entering the clear liquid chamber, which may cause the separated clear liquid to become turbid, affecting the quality of the clear liquid and reducing the separation effect, and better meeting the needs of users.
