Description

Technical Field

[0001] This utility model relates to the technical field of mud cleaning equipment, specifically to an integrated mud cleaning machine for treating oily mud. Background Technology

[0002] Oil sludge is generated during wastewater treatment in oil development, transportation, and refining. It is a mixture of silt, minerals, and other impurities containing crude oil or refined oil. The oil content exists in multiple forms within this mixture and cannot be directly recovered, leading to increasing environmental pollution. When rainwater soaks into the oil sludge, it flows into farmland and rivers, depriving the water of dissolved oxygen. Simultaneously, the degradation of the oil by microorganisms consumes large amounts of oxygen, causing severe oxygen depletion in aquatic bodies and damaging aquatic ecosystems.

[0003] A search revealed that Chinese patent publication number CN 217662846 U discloses an easy-to-clean oil sludge pretreatment device, comprising a frame, a treatment tank fixedly mounted on the top of the frame, a movably fitted lid on the top of the treatment tank, a stirring motor fixedly mounted at the center of the top of the lid, a spray pipe inserted into one side of the stirring motor and located inside the treatment tank, maintenance ports and liquid outlets respectively provided on the outer surface sidewall of the treatment tank, a base provided below the frame, a water tank provided on one side of the top of the base, and a control box fixedly mounted on the same side of the frame and the water tank. This device has a compact and reasonable structural design, is easy to use, and can automatically treat oily sludge in an integrated manner without the need for additional auxiliary equipment, greatly improving work efficiency and reducing oil sludge treatment costs. It has strong practicality, and the device is also easy to disassemble, maintain, and clean, effectively extending the service life of the equipment.

[0004] The oil sludge treatment device in the aforementioned patent still has certain shortcomings. Because the existing oil sludge treatment and sludge cleaning machines have a relatively simple structure in actual use, it is difficult to fully crush the sludge blocks in the oil sludge. As a result, the sludge after cleaning still contains a large number of oil molecules. If it is carelessly discharged into the environment, it will cause environmental pollution. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an integrated mud cleaning machine for treating oily sludge. This solves the problem that existing oily sludge cleaning machines have a relatively simple structure and are difficult to fully crush the mud lumps in the oily sludge, resulting in the mud still containing a large number of oil molecules after cleaning. If these are carelessly discharged into the environment, they will cause environmental pollution.

[0006] This utility model provides the following technical solution: an integrated mud cleaning machine for treating oily sludge, including a mud cleaning chamber, two support legs symmetrically arranged on both sides of the bottom end of the mud cleaning chamber, a mud cleaning component on the mud cleaning chamber, and an oil discharge component on the mud cleaning chamber;

[0007] The mud cleaning assembly includes two drive rods symmetrically arranged at the bottom of the mud cleaning chamber. The ends of the drive rods are rotatably connected to the inner wall of the mud cleaning chamber. Several crushing blades are evenly arranged on each drive rod. A transmission rod is provided at the end of each drive rod, rotatably penetrating the mud cleaning chamber. A pulley is provided at the end of each transmission rod, and the two pulleys are connected by a transmission belt. A drive motor is located on the side of the mud cleaning chamber, and the drive shaft of the drive motor rotatably penetrates the mud cleaning chamber and is fixedly connected to the end of the drive rod. A mud pump is located at the bottom of the mud cleaning chamber, with a suction pipe connected to its input end. The top end of the suction pipe extends to the bottom of the mud cleaning chamber. A filter cover is located at the bottom of the mud cleaning chamber, fitted over the end of the suction pipe. A delivery pipe is connected to the other side of the mud pump, and a first valve is provided on the delivery pipe. A mud discharge pipe is connected to the side of the mud pump, and a second valve is provided on the mud discharge pipe.

[0008] Preferred technical solution 1: The oil discharge component includes an oil discharge pipe disposed on the side of the mud cleaning chamber, and a third valve is provided on the oil discharge pipe.

[0009] Preferred technical solution 2: An oil collection chamber is provided on the outside of the mud cleaning chamber, and the bottom end of the oil collection chamber is fixedly connected to the mud cleaning chamber through a support plate.

[0010] Preferred technical solution 3: The two sides of the bottom of the mud cleaning chamber are inclined inward.

[0011] This design allows the mud fed into the mud cleaning chamber to fall more effectively to the bottom of the chamber and be cut and broken by the crushing blades on the drive rod.

[0012] Preferred technical solution four: a plurality of the crushing blades are evenly arranged on the drive rod, and the plurality of the crushing blades are staggered on the drive rod.

[0013] This design enables several interleaved cutting blades on the drive rod to better cut and break up clumps in the mud, increasing the contact area between the soil in the mud and the clean water, thereby allowing oil molecules to be better released.

[0014] Preferred technical solution five: The top end of the conveying pipe extends to the top of the mud cleaning chamber, and the conveying pipe is connected to the mud cleaning chamber through a fixing ring.

[0015] This solution enables a more stable fixation between the delivery pipe and the mud cleaning chamber.

[0016] Compared with the prior art, this utility model provides an integrated mud cleaning machine for treating oily sludge, which has the following beneficial effects: This utility model is equipped with a mud cleaning component and an oil discharge component on the mud cleaning chamber. The drive rod in the mud cleaning component can drive the crushing blade to crush the lumps contained in the mud. The rotation of the crushing blade can mix the crushed mud with clean water, so that the oil molecules contained in the mud can be better decomposed. The mud pump can pump the mud located at the bottom of the mud cleaning chamber again and put it back into the top of the mud cleaning chamber through the delivery pipe, which can improve the mixing of mud and clean water and accelerate the decomposition of oil molecules contained in the mud, so that the mud is effectively cleaned. The liquid floating on the top of the clean water is discharged into the oil collection chamber for treatment through the oil discharge pipe. The treated mud can meet the environmental protection emission standards. Attached Figure Description

[0024] Please see Figure 1-4 ,

[0025] Example 1: A mud cleaning machine for treating oily sludge includes a mud cleaning chamber 1, two support legs 2 symmetrically arranged on both sides of the bottom end of the mud cleaning chamber 1, a mud cleaning component 3 on the mud cleaning chamber 1, and an oil discharge component 4 on the mud cleaning chamber 1.

[0026] The mud cleaning assembly 3 includes two drive rods 301 symmetrically arranged at the bottom of the mud cleaning chamber 1. The ends of the drive rods 301 are rotatably connected to the inner wall of the mud cleaning chamber 1. Several crushing blades 302 are evenly arranged on the drive rods 301. A transmission rod 303 is provided at the end of each drive rod 301. The end of the transmission rod 303 rotatably passes through the mud cleaning chamber 1. A pulley 304 is provided at the end of each transmission rod 303. The two pulleys 304 are connected by a transmission belt 305. A drive motor 306 is provided on the side of the mud cleaning chamber 1. The drive shaft of the drive motor 306 rotatably passes through the mud cleaning chamber 1 and is fixedly connected to the end of the drive rod 301.

[0027] A mud pump 307 is installed at the bottom of the mud cleaning chamber 1. The input end of the mud pump 307 is connected to a suction pipe 308. The top end of the suction pipe 308 extends to the bottom of the mud cleaning chamber 1. A filter cover 309 is installed at the bottom of the mud cleaning chamber 1. The filter cover 309 is fitted onto the end of the suction pipe 308. A conveying pipe 310 is connected to the other side of the mud pump 307. A first valve 311 is installed on the conveying pipe 310. A mud discharge pipe 312 is connected to the side of the mud pump 307. A second valve 313 is installed on the mud discharge pipe 312.

[0028] The oil discharge assembly 4 includes an oil drain pipe 401 located on the side of the mud cleaning chamber 1, a third valve 402 located on the oil drain pipe 401, an oil collection chamber 403 located on the outside of the mud cleaning chamber 1, and the bottom end of the oil collection chamber 403 being fixedly connected to the mud cleaning chamber 1 via a support plate 404.

[0029] Example 2: The difference between this example and Example 1 is that the two sides of the bottom of the mud cleaning chamber 1 are inclined inward.

[0030] This allows the mud fed into the mud cleaning chamber 1 to fall more effectively into the bottom of the mud cleaning chamber 1 and be cut and broken by the crushing blade 302 on the drive rod 301.

[0031] Example 3: The difference between this example and Example 1 is that a number of crushing blades 302 are evenly arranged on the drive rod 301, and the number of crushing blades 302 are staggered on the drive rod 301.

[0032] This allows the multiple crushing blades 302, which are staggered on the drive rod 301, to better cut and break up the clumps in the mud, increasing the contact area between the soil in the mud and the clean water, thereby allowing oil molecules to be better released.

[0033] Example 4: The difference between this example and Example 1 is that the top end of the conveying pipe 310 extends to the top of the mud cleaning chamber 1, and the conveying pipe 310 is connected to the mud cleaning chamber 1 through a fixing ring.

[0034] This makes the fixation between the delivery pipe 310 and the mud cleaning chamber 1 more stable.

[0035] In this embodiment, because the existing oil sludge treatment and sludge cleaning machine has a relatively simple structure in actual use, it is difficult to fully crush the sludge blocks in the oil sludge. As a result, the sludge after cleaning still contains a large number of oil molecules. If it is rashly discharged into the environment, it will cause environmental pollution.

[0036] In summary, in practical implementation, when a user needs to clean mud containing oil, the user can put the oily mud into the mud cleaning chamber 1, add clean water to the mud cleaning chamber 1 at the same time, and start the drive motor 306 in the mud cleaning component 3. The drive motor 306 drives the drive rod 301 to rotate. The ends of the two drive rods 301 are connected by a transmission belt 305 wound on the pulley 304, so that the two drive rods 301 can rotate at the same time. The drive rods 301 drive the several crushing blades 302 set on them to rotate. When the clumps contained in the mud fall to the bottom of the mud cleaning chamber 1, they will be cut into smaller volumes by the rotation of the crushing blades 302, thereby increasing the contact area between the soil and water in the mud, so that the oil molecules contained in the mud can be better separated. The rotating crushing blades 302 can also agitate the water, accelerating the separation of oil molecules.

[0037] The crushed mud mixture is collected at the bottom of the mud cleaning chamber 1. In order to ensure that the mud can be fully mixed with clean water and improve the removal of oil stains, the mud pump 307 is started. The mud pump 307 pumps the crushed mud at the bottom of the mud cleaning chamber 1 into the delivery pipe 310 through the suction pipe 308. The mud is then added to the upper part of the mud cleaning chamber 1 and mixed with clean water through the delivery pipe 310, thereby effectively improving the removal of oil stains from the mud. When the oil stains in the mud have been sufficiently removed, the second valve 313 is opened and the first valve 311 is closed, so that the cleaned mud in the mud cleaning chamber 1 is pumped by the mud pump 307 into the mud discharge pipe 312 and discharged through the mud discharge pipe 312.

[0038] While the mud is being discharged, the oily wastewater floating on the water surface drops to the oil discharge pipe 401 in the oil discharge component 4, and can then be discharged through the oil discharge pipe 401 and collected through the oil collection chamber 403, thereby completing the mud cleaning operation of the oily mud, so that the mud can be cleaned more thoroughly and meet the requirements of environmentally friendly discharge.
