SUMMARY

[0003] The utility model solves the technical problem of how to avoid the accumulation of a large amount of solid deposit at the bottom of the sedimentation separation device and ensure the normal operation of the sedimentation separation device.

[0004] The utility model employs the technical scheme that a sedimentation separation device, including the sedimentation bin, be equipped with the feed inlet and the discharge gate on the sedimentation bin, be equipped with the cleaning mechanism in the sedimentation bin, the cleaning mechanism includes slide rail, sliding block, lead screw, bevel gear set, motor, cleaning plate, guide rail and fixed link, wherein the slide rail is installed in the inner wall of the sedimentation bin, and the slide rail is oppositely provided with two, the lead screw is rotatably connected in one of the slide rail, and the guide rod is installed in another slide rail, one end of the lead screw is connected with the motor, the motor is installed on the top plate of the sedimentation bin, the motor is connected with the lead screw through the bevel gear set, the lead screw and the guide rod are all connected with the sliding block, and the cleaning plate is connected between the sliding block.

[0005] After adopting the above structure, the following beneficial effects are obtained:

[0006] (1) the motor drives the lead screw to rotate, and then drives the sliding block and the cleaning plate to move along the slide rail, which realizes the automatic cleaning of the inner wall of the sedimentation bin, reduces the manual intervention, and effectively saves the cleaning time.

[0007] (2) the design of the slide rail, the lead screw and the guide rod ensures the stable movement of the cleaning plate, avoids the possible sticking or deviation problem during operation, and improves the stability of equipment operation.

[0008] (3) the cleaning plate is connected to the lead screw and the guide rod through the sliding block, can cover most of the area of the inner wall of the sedimentation bin, and can be replaced according to the different shapes of the sedimentation bin, so as to realize better cleaning effect of the inner wall of the sedimentation bin.

[0009] (4) The automatic cleaning reduces the risk of equipment failure caused by residue accumulation, prolongs the service life of the equipment, is suitable for sedimentation separation requirements under various working conditions, and regularly removing residues on the inner wall of the sedimentation tank also effectively reduces the influence of residues on the separation effect of the material, thereby ensuring the stability and reliability of the long-term operation of the sedimentation separation device.

[0010] Preferably, the inside of the cleaning plate is provided with a gas guide pipe, a water guide pipe and a conveying pipe, the gas guide pipe and the water guide pipe are both connected with the conveying pipe, and the conveying pipe is bifurcated at the discharge port of the cleaning plate.

[0011] The gas guide pipe is used to convey high-pressure gas, and the impact force of the gas is used to remove loose attachments, and then water flow is introduced through the water guide pipe to remove small particles and grease through the scouring action of the water flow. This multi-stage cleaning method significantly improves the cleaning efficiency; and the discharge port of the conveying pipe is designed to be bifurcated, which can ensure the cleaning condition during the cleaning process, ensure that the cleaning process is more comprehensive and thorough, and reduce the time used for cleaning.

[0012] Preferably, a guide rail is arranged on the top surface of the cleaning plate, and a scraper for cleaning stubborn solid deposits is slidably connected to the guide rail.

[0013] The scraper can mechanically scrape off the stubborn solid deposits on the inner wall of the sedimentation tank, which is an effect that cannot be achieved by simply relying on gas impact or water scouring. The stubborn residues are cleaned in a timely manner, reducing the need for manual cleaning, reducing labor intensity, and avoiding corrosion or damage caused by long-term attachment of stubborn solid deposits on the inner wall of the sedimentation tank, thereby prolonging the service life of the equipment.

[0014] Preferably, a groove is arranged inside the guide rail, a fixing rod is arranged inside the groove, an elastic member is mounted on the fixing rod, and a boss is arranged on the bottom surface of the scraper, one end of the elastic member abuts against the inner wall of the groove, and the other end abuts against the boss.

[0015] By arranging a fixing rod inside the groove and mounting an elastic member on the fixing rod, and abutting the two ends of the elastic member against the inner wall of the groove and the boss respectively, the scraper can adapt to the inner wall of the sedimentation tank with different shapes and materials when moving. Whether it is a plane, an inclined plane or a curved surface, it can maintain good adhesion and the scraper can effectively remove stubborn solid deposits by providing appropriate pressure through the elastic member, avoiding the decrease of cleaning effect caused by insufficient or excessive pressure. In addition, when the cleaning is completed, the scraper can also return to the preset position under the action of the elastic member.

[0016] Preferably, the guide rail is provided with limiting protrusions on both sides, which are matched with the scraper.

[0017] By providing limiting protrusions on both sides of the guide rail, the vertical movement distance of the scraper can be effectively limited, avoiding the risk of the scraper falling off the guide rail due to external force or vibration during movement, ensuring the continuity and safety of the cleaning process. The cooperation of the limiting protrusions and the scraper also makes the movement of the scraper on the guide rail more stable, reducing unnecessary shaking or jamming, thereby improving the stability of the equipment operation.

[0018] Preferably, the discharge port includes a first discharge port and a second discharge port, the first discharge port is arranged on the side wall of the settling tank, and a plurality of discharge outlets are arranged near one side of the settling tank.

[0019] By arranging the first discharge port on the side wall of the settling tank and providing multiple discharge outlets, different density liquid substances such as oil and water can be discharged. This layered discharge design can effectively avoid the problem of oil and water mixing, and the design of multiple discharge outlets significantly improves the discharge efficiency of liquid substances, shortens the separation and discharge time, and improves the overall work efficiency. In addition, the design of multiple discharge outlets can more comprehensively cover the distribution area of liquid substances, reducing the liquid residue phenomenon caused by a single outlet.

[0020] Preferably, the second discharge port is arranged at the bottom of the settling tank, and a plurality of round holes are arranged on the second discharge port.

[0021] By arranging multiple round holes on the second discharge port, solid sediments can be uniformly discharged, effectively avoiding the local accumulation phenomenon that may be caused by a single traditional outlet. Compared with the design of a single large opening, the risk of blockage caused by large particles or strong adhesion of solid sediments can be significantly reduced. In addition, when solid sediments need to be discharged, the pressure inside the second discharge port can be reduced to make the sediments enter the round holes and be discharged along the pipe diameter direction of the second discharge port, thereby realizing an efficient and stable discharge process. This design not only simplifies the operation process, but also improves the reliability and separation effect of the equipment operation.

[0022] Preferably, the wall of the settling tank is provided with a heat preservation layer, and the heat preservation layer is internally provided with a heating element.

[0023] The heat preservation layer can effectively prevent the heat inside the settling tank from being transmitted to the outside, thereby maintaining a stable temperature environment in the settling tank. Especially for materials after three-phase separation, the oil and water contained therein need to ensure good fluidity when discharged, and stable temperature can help avoid material solidification or increased viscosity caused by temperature difference, thereby accelerating the discharge speed and reducing the possibility of blockage.
