Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a plug spiral sewage discharge solid-liquid separation device. Background Art

[0002] The plug screw uses spiral extrusion to crush the raw material, forming a plug, which lays the foundation for the subsequent softening and cooking process in the pulping process. The washed raw material is pre-steamed in a steaming chamber to balance the moisture content and initially soften it. The raw material, which contains approximately 40% moisture, is then squeezed to remove most of the free water and insoluble matter. This solid-liquid mixture is discharged through the plug screw drain pipe to the workshop ditch and then treated by the water treatment department. Existing solid-liquid mixtures typically require high-pressure sludge pumps for suction, which is costly. Furthermore, the wastewater discharged through the ditch has high SS and COD content. The water-containing raw material after washing is squeezed, causing water loss in the system, necessitating additional water washing and replenishment of the system raw material, increasing consumption. Therefore, draining the material into the ditch is prone to pollution and wastes resources.

[0003] To address the shortcomings of existing technologies, researchers have conducted extensive research and proposed various solutions. For example, a Chinese patent document discloses a solid-liquid separation device (CN202123210217.X) mounted on a sewage pipe. The device comprises a sewage pipe, a water inlet at one end of the pipe, and a water outlet at the other end. The bottom of the sewage pipe is detachably connected to at least one slag collection barrel for collecting particles in sewage. The bottom of the sewage pipe is provided with a slag collection hole connected to the slag collection barrel. A slag collection block is provided at the bottom of the sewage pipe, located near the water outlet and configured to prevent sewage from flowing through the slag collection hole and forming a flocculent flow.

[0004] The above solution solves the problem of high cost of using high-pressure sludge pumps for suction in the prior art to a certain extent.
