A separation tower is a device that can separate multiple mixed substances. In the process of separating industrial mixed oil, the separation tower is an essential piece of equipment.

[0003] However, existing industrial-grade oil separation towers still have the following problems during use: While existing industrial-grade separation towers for mixed oils can separate mixed oils from slag, the slag still contains a large amount of residual mixed oil. Since the slag is not further processed, the mixed oil is wasted. Therefore, it is necessary to develop an industrial-grade separation tower for mixed oils to be used in the field of existing mixed oil processing equipment. Utility Model Content

[0013] The advantages of this utility model are: This invention involves dropping residue containing a large amount of mixed oil into a filter screen through a discharge pipe. Activating the cylinder causes the piston rod to move the adjusting block. Under the action of two adjusting rods, the traction block moves along two guide rods. When the two clamping plates approach each other, they squeeze the residue containing the large amount of mixed oil on the filter screen. The squeezed mixed oil flows from the connecting pipe into the collection box. At this time, the push plate is located on one side of the two clamping plates. When the two clamping plates move away from each other, the adjusting block moves the guide rod, which in turn moves the push plate between the two clamping plates, pushing the pressed residue out of the squeezing area. The pressed residue pushes against each other, causing it to fall out of the discharge port. By squeezing the residue to extract and collect the mixed oil, the operation efficiency is improved, and waste of the mixed oil is avoided. Attached Figure Description

A collection box 20 is fixedly mounted at the bottom of the transfer cylinder 13, located on one side of the discharge pipe 22. A connecting pipe 82 is fixedly mounted on the side of the collection box 20. A separation box 83 is fixedly mounted at one end of the connecting pipe 82, and the discharge pipe 22 is located inside the separation box 83. The separation box 83 is equipped with a compression unloading mechanism 90, which includes a cylinder 9000. A slag discharge port 9001 is symmetrically arranged on the bottom surface of the separation box 83. A stop block 9002 is symmetrically and fixedly mounted on the bottom surface of the separation box 83, located between the two slag discharge ports 9001. A filter screen 9003 is fixedly mounted between the two stop blocks 9002, located below the unloading pipe 22. The interior of the connecting pipe 82 communicates with the interior of the separation box 83. The connecting pipe 82 is located between the two stop blocks 9002 and below the filter screen 9003 at its internal connection point within the separation box 83. The filter 9003 is symmetrically provided with traction ports 9004. Guide rods 9005 are symmetrically fixedly mounted on each traction port 9004. Traction blocks 9006 are movably mounted on each guide rod 9005. Connecting blocks 9007 are fixedly mounted on each traction block 9006. A clamping plate 9008 is fixedly mounted on one end of each connecting block 9007. The clamping plate 9008 is located above the filter screen 9003. An L-shaped support frame 9009 is fixedly mounted on the separation box 83. A cylinder 9000 is fixedly mounted on the L-shaped support frame 9009. A piston rod 9010 is fixedly mounted on the output end of the cylinder 9000. The piston rod 9010 movably passes through the L-shaped support frame 9009. Furthermore, an adjusting block 9011 is fixedly mounted on one end of the piston rod 9010, and a guide rod 9012 is fixedly mounted on the adjusting block 9011.

[0019] In this invention, slag containing a large amount of mixed oil residue falls from the discharge pipe 22 into the filter screen 9003. The cylinder 9000 is activated, causing the piston rod 9010 to move the adjusting block 9011. Under the action of the two adjusting rods 9015, the traction block 9006 moves on the two guide rods 9005.

At this time, the push plate 9013 is located on one side of the two clamping plates 9008. When the two clamping plates 9008 move away from each other, the adjusting block 9011 drives the guide rod 9012 to move. The guide rod 9012 drives the push plate 9013 to move between the two clamping plates 9008, pushing the pressed residue out of the extrusion area. With the mutual pushing of the pressed residue, the pressed residue falls out from the discharge port 9001. By extruding the residue, the mixed oil is collected, improving the operation efficiency and avoiding the waste of mixed oil.
