Description

Technical Field

[0001] This utility model relates to the field of oil sludge extraction technology, and in particular to an extraction device for the treatment of oily sludge. Background Technology

[0002] Oily sludge is composed of water, oil, and suspended solids, making it difficult to treat. It is frequently required in wastewater treatment plants of oil refineries, shipbuilding areas, and steel smelting plants. For small areas of oily sludge, excavators can be used in conjunction with transfer tanks / containers for transport. For larger areas of oily sludge, extraction equipment is more efficient for extraction, transportation, and treatment.

[0003] There are some existing studies on oily sludge extraction, such as the Chinese invention patent with application number CN202410576401.5 entitled "An Oily Sludge Extraction Device". It can transport oily sludge into the extraction container, but it mainly uses a stirring device to stir the oily sludge and separate and extract the oil from the extraction agent solution. Its applicability to oily sludge extraction in environmental remediation scenarios is not high.

[0004] For example, Chinese invention patent application number CN202410415342.3, entitled "An Oil Sludge Extraction System," utilizes the heat introduced by heating gas to heat the extraction solvent, accelerating the separation of light tar from sludge, making the extraction process more thorough, and increasing the oil yield of light tar from oil sludge. However, its applicability to oil sludge extraction in environmental remediation scenarios is also not high. Summary of the Invention

The two first support columns 3 are connected and fixed to the base plate 1 by connecting rings welded to their bottom ends. The first support columns 3 are used to support the second pipe body 23. The connecting rings are connected to the base plate 1 by long bolts for easy installation and disassembly. The front end of the first screw 25 is rotatably mounted in the first tube 21, and the rear end of the second screw 26 is rotatably mounted in the second tube 23. The first screw 25 and the second screw 26 are connected by a connecting block 27, allowing the two screws to rotate. The drive structure is connected to the rear end of the second screw 26, driving the second screw 26 to rotate. An end cap 28 is disposed between the drive structure and the second screw 26. The mud outlet 24 is located at the rear bottom end of the first tube 21. Mounting seats 31 are provided at the rear bottom end of the first tube 21 and the front bottom end of the second tube 23. A second first support column 32 is installed between the two mounting seats 31 to support the first tube 21 and prevent it from tipping over. A feed inlet is provided at the front of the second tube 23, and a filter cover 6 is installed outside the feed inlet to filter out large objects such as stones in the sludge.

[0022] Specifically, refer to Figures 1-2 As shown, the drive structure includes a rear movable support frame 53, a frame 54, and a geared motor 55. The geared motor 55 is fixed to the top of the rear movable support frame 53 via the frame 54. The drive end of the geared motor 55 is connected to the end of the second screw 26.

The first support columns 3 and the base plate 1 are connected by bolts for easy installation and disassembly. In scenarios requiring relocation, the two first support columns 3 are not fixed to the base plate 1. Instead, a front moving support assembly 4 and a rear moving support assembly 5 cooperate to support the extraction device for treating oily sludge. It can be moved as needed to move the feed inlet at the front of the second tube 23 to the oily sludge area for better adsorption and extraction. During operation, the reduction motor 55 drives the second screw 26 to rotate, causing the first screw 25 and the second screw 26 to rotate within the first tube 21 and the second tube 23, extracting the oily sludge. The extracted sludge is then discharged from the sludge outlet 24 and transported through a conveying pipeline, enabling continuous extraction of oily sludge with high efficiency.
