DETAILED DESCRIPTION

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0016] A sludge separation device for a sorbitol production line, such as Figure 1 to Figure 2 As shown, it includes a drawer-type collecting box 1, a conical separator, and a water collecting part 7. The conical separator is installed on the top of the collecting box 1 through a bracket 2, and the bottom end of the conical separator is connected to the collecting box 1, the upper part of the conical separator is connected to the feed pipe 5, and the conical separator and the water collecting part 7 are connected by a connecting flange 6. An overflow port is opened on the upper part of the water collecting part 7 and is connected to the outlet pipe 8 through the overflow port.

[0017] The conical separator includes a conical drop portion 3 connected to the collecting box 1 and a vortex chamber 4 arranged at the top of the drop portion 3. The upper part of the vortex chamber 4 is connected to the feed pipe 5, and the initial feeding direction of the feed pipe 5 is tangent to the edge of the vortex chamber 4, which can ensure that the sludge entering the vortex chamber 4 is quickly driven by the airflow inside the vortex chamber to rotate downward, and finally enters the collecting box 1 for collection.

[0018] The top of the vortex chamber 4 is closed, as shown in FIG. Figure 2As shown, an overflow pipe 10 is provided inside the vortex chamber 4 and passes through the top center of the vortex chamber 4 and is connected to the water collecting part 7. This can ensure that the water flow, driven by the vortex airflow, spirals upward and separates from the sludge and flows upward to the water collecting part 7 through the overflow pipe 10.

[0019] A one-way valve 11 is installed on the upper part of the overflow pipe 10 located above the vortex chamber 4 to prevent the separated water from flowing back.

[0020] The water collecting part 7 includes a transition layer 13 and a clean water layer 14 . The transition layer 13 is located below the clean water layer 14 . An overflow port is provided on the top of the clean water layer 14 , and the clean water layer 14 is connected to the water outlet pipe 8 through the overflow port.

[0021] A detachable blocking screen plate 12 is provided between the transition layer 13 and the clean water layer 14, which can perform secondary screening on small particle impurities that enter the water collecting part 7 along with the water flow.

[0022] An umbrella-shaped protective cover 9 is provided on the top of the water collecting part 7 to prevent impurities from mixing into the separated clean water from the top.

[0023] During specific use, the sludge and sewage mixture enters the conical separator from the feed pipe 5 for separation, and spirally rotates downward under the action of the airflow inside the vortex chamber 4. When it touches the bottom of the drop portion 3, the sewage and a part of the small particles rise in a reverse inward spiral and enter the water collection portion 7 through the overflow pipe 10, while the sludge directly enters the collection box 1 for collection.

[0024] The sewage and small particles entering the water collecting part 7 are accumulated in the water collecting part 7, and are screened by the blocking sieve plate 12, so that the clean water is accumulated upward to the overflow port and is collected through the outlet pipe 8, while the small particles are intercepted by the blocking sieve plate 12 and are transported to the transition layer 13.

[0025] The utility model provides a sludge separation device for a sorbitol production line, which effectively separates sewage and sludge by arranging a conical separator, and at the same time performs secondary screening on the separated sewage by arranging a blocking sieve plate, thereby ensuring the purity of the separated sewage and sludge, and facilitating secondary utilization in the later stage.
