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

[0003] At present, the common ways of slag discharge for disc separators are full slag discharge by ring valve, partial slag discharge by ring valve and nozzle slag discharge. The above slag discharge methods have a common disadvantage that the discharged slag is all solid-liquid slag, and the solid-liquid mixed slag is discharged through the slag discharge pipe at the same time. Some residues are directly discarded. Some types of solid residues need to be dried and collected, but the liquid content is too high and the subsequent drying time is too long, which affects the production efficiency.

DETAILED DESCRIPTION

[0021] Please refer to the attached Figure 1-Figure 3 Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0022] The utility model proposes a slag discharge mechanism for a disc separator. Before use, the extrusion plate 11 is at the highest position, the lower side of the extrusion plate 11 is higher than the slag inlet pipe 6, and a pair of connecting rods 14 are located in the corresponding through holes 12. Figure 1As shown, when the device is used, the slag discharge method of the disc separator is that when the residue accumulates to a certain time or a certain weight, the slag discharge port is opened for slag discharge. When the slag discharge port is opened, the solid and liquid slag are sprayed into the slag discharge tank 13 through the slag inlet pipe 6, and the solid and liquid slag fall on the filter plate 7. When a round of solid and liquid slag discharge is completed, the slag discharge port is closed, and the motor 1 is started. The motor 1 drives the threaded cylinder 2 to rotate, and the threaded cylinder 2 drives the screw 3 to slide downward. The screw 3 drives the extrusion plate 11 to slide downward along the slag discharge tank 13, and the extrusion plate 11 drives a The guide rod 5 slides downward along the corresponding sleeve 4, and the pair of through holes 12 of the extrusion plate 11 slides downward along the corresponding blocking rod 15. The through holes 12 are blocked by the blocking rod 15 to prevent the liquid from flowing to the top of the extrusion plate 11 through the through holes 12 during extrusion, thereby affecting the effect of extrusion dehydration. The extrusion plate 11 squeezes the solid-liquid slag to squeeze out a large amount of liquid remaining in the solid-liquid slag. The liquid in the solid-liquid slag flows out through the filter plate 7, and the liquid is discharged through the liquid outlet pipe. When the pressure sensor senses the extrusion pressure on the solid-liquid slag to After the set value, the motor 1 stops (if it is a disc-type separator that discharges slag after accumulating a certain gram weight, it is not necessary to install a pressure sensor, and the descending depth of the extrusion plate 11 can be set). After standing for a while until the waste liquid is no longer discharged in a flow, the motor 1 is started again, and the motor 1 reverses to drive the extrusion plate 11 to slide upward to the initial position. At the same time, the movable door 9 is started, and the movable door 9 is opened. The solid and liquid slag after extrusion is discharged along the discharge plate 8. The solid and liquid slag after extrusion is in a moist state, rather than a wet or even solid-liquid mixed state, which is convenient for subsequent drying. The device is easy to operate and does not increase the floor space. It can achieve the purpose of dehydrating a large amount of solid and liquid slag in a short time, reduces the time used for subsequent drying, and improves the efficiency of subsequent drying of solid and liquid slag. After the disc-type separator is used, the CIP cleaning system is started, and the cleaning liquid is sprayed into the slag discharge tank 13 through a pair of cleaning pipes 10 to clean the slag discharge tank 13. The cleaning liquid on the extrusion plate 11 flows out through a pair of through holes 12. After the slag discharge tank 13 is cleaned, the device is restored to its initial state.
