Description

[0001] The utility model relates to the technical field of petroleum sludge separation, in particular to a cyclone sedimentation tank. Background Art

[0002] With the rapid development of the petroleum industry, the amount of oily sludge generated during oil extraction, processing, and transportation is increasing. This type of sludge not only contains a large amount of recyclable oil, but may also cause serious pollution to the environment.

[0003] Existing cyclone sedimentation tanks mainly rely on the centrifugal force generated by the cyclone to achieve solid-liquid separation when treating oily sludge. However, due to the complex composition of oily sludge and the strong interaction between oil, water and solid particles, agglomerates will be formed. The presence of agglomerates in the liquid may change the viscosity of the liquid, especially when the number of agglomerates is large or the size is large. The change in viscosity will affect the fluidity of the liquid, thereby affecting the filtration rate or sedimentation rate in the solid-liquid separation process.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides a technical solution: it includes a sedimentation box and a separation tank 1, and a separation component installed in the separation tank 1, a separation chamber 101 is opened in the separation tank 1, a column 103 is arranged on the bottom surface of the separation tank 1, there are three columns 103, and the three columns 103 are arranged in a circular array with equal intervals, the separation component includes a top cover 2, the top cover 2 is threadedly connected to the top surface of the separation tank 1, a feed port 201 is opened on one side of the top cover 2, a one-way valve is arranged in the feed port 201, the feed port 201 is communicated with the separation chamber 101, a motor 3 is arranged above the top cover 2, the output shaft of the motor 3 is fixedly connected with a driving gear 4 and a driving wheel 5, the driving gear 4 is meshed with a driven gear 7, and a belt is provided between the driving wheel 5 and the driven wheel 6.

[0022] A driven wheel 6 is rotatably connected in the top cover 2, and a driven gear 7 is rotatably connected in the driven wheel 6. A separation frame 602 is connected below the driven wheel 6, and a separation rod 702 is connected below the driven gear 7. A rotating rod is arranged below the driven wheel 6, and a through hole is opened on the top surface of the driven wheel 6, which passes through the end of the rotating rod. The end of the rotating rod is fixedly connected to a connecting frame 601, and both ends of the connecting frame 601 are fixedly connected to the inner wall of the separation frame 602. A plug rod is arranged on the bottom surface of the driven gear 7, and the plug rod passes through the through hole and is inserted into the separation chamber 101. The end of the plug rod is located below the connecting frame 601, and one end of the extension plate is fixedly connected to the end of the plug rod. The middle section of the extension plate is fixedly connected to the separation rod 702. A solid outlet 603 connected thereto is opened at the bottom end of the separation frame 602, and a liquid outlet 102 connected thereto is opened on the outer side of the bottom surface of the separation chamber 101, and switch valves are installed in both the liquid outlet 102 and the solid outlet 603.

[0023] By adopting the above design, when the starting motor 3 drives the driving gear 4 and the driving wheel 5 to rotate clockwise, because the driving gear 4 is engaged with the driven gear 7, the driven gear 7 will drive the separation rod 702 to rotate in the opposite direction. Because the driven wheel 6 and the driving wheel 5 are driven by a belt, the driven wheel 6 will drive the separation frame 602 to rotate clockwise, thereby making the rotation direction of the separation rod 702 opposite to that of the separation frame 602.

[0024] Therefore, after pouring the oily sludge into the separation frame 602 through the feed port 201, the motor 3 can be started to drive the separation frame 602 to rotate to separate the solid and liquid of the sludge. At this time, the separation rod 702 will rotate in the separation frame 602 in the opposite direction, and then during the solid-liquid centrifugal separation, the oil, water, and solid particles in the sludge are broken up, and agglomerates are formed due to the strong interaction force, thereby reducing the viscosity of the sludge, increasing the fluidity of the sludge, and realizing the rapid solid-liquid separation of the oily sludge.

[0025] After the solid-liquid separation is completed, the motor 3 is turned off, and the valve in the solid outlet 603 is opened to take out the separated solid from the solid outlet 603. The sedimentation tank is placed below the liquid outlet 102, and the valve in the liquid outlet 102 is opened to take out the separated liquid. After the liquid is precipitated in the sedimentation tank, the oil separation operation of the oily sludge is completed.

[0026] See also Figure 2 and Figure 3 Furthermore, the other end of the extension plate is fixedly connected to a cleaning rod 701 that contacts the inner wall of the separation frame 602. An annular groove is provided on the bottom surface of the top cover 2. The top surface of the separation frame 602 is rotatably connected in the annular groove. The top surface of the connecting frame 601 contacts the bottom surface of the top cover 2. The bottom end of the separation frame 602 is conical, and the outer wall of the bottom end of the separation frame 602 is rotatably sealed and connected to the center of the bottom surface of the separation chamber 101.

[0027] By providing a cleaning rod 701 that contacts the separation frame 602, the cleaning rod 701 can continuously scrape the inner wall of the separation frame 602 during rotation to prevent sludge from clogging the mesh holes on the separation frame 602 and thus affecting the separation efficiency.

[0028] By opening an annular groove on the bottom surface of the top cover 2, the top end of the separation frame 602 is rotatably connected in the annular groove, and the connecting frame 601 is in contact with the bottom surface of the top cover 2, so that during the process of the separation frame 602 rotating to centrifuge the sludge therein, the sludge will not splash out from the gap between the separation frame 602 and the bottom surface of the top cover 2, and even if the sludge adheres to the bottom surface of the top cover 2, it will be scraped off by the connecting frame 601.

[0029] By setting the bottom surface of the separation frame 602 to be conical, during the rotation, the sludge will rise along the conical surface of the separation frame 602 under the influence of centrifugal force and will not accumulate at the bottom of the separation tank 1, thereby causing incomplete separation and cleaning.

[0030] By adopting the above design, after the separation is completed, the motor 3 can be turned off, and then the liquid is taken out for sedimentation, and then the motor 3 is turned on again, and the container containing the solid is placed under the separation frame 602, and the valve is opened to collect the solid. At this time, the attachments on the bottom surface of the top cover 2 and the attachments on the side walls of the separation frame 602 will be continuously scraped off by the connecting frame 601 and the cleaning rod 701, thereby achieving the purpose of cleaning the inside of the separation frame 602 after use.

[0031] In addition, reference Figure 1 A protective cover 8 is installed on the top surface of the top cover 2, and the motor 3 is fixedly connected to the top surface inside the protective cover 8, and a heat dissipation mesh is opened on the top surface of the protective cover 8.

[0032] By adopting the above design, the motor 3 has good heat dissipation and ventilation effects while preventing foreign matter from entering the transmission parts of the driving gear 4, the driving wheel 5, the driven wheel 6, and the driven gear 7, thereby preventing the operation of the device from occurring.

[0033] Working principle:

[0034] When in use, the oily sludge is first poured into the separation frame 602 through the feed port 201, and then the motor 3 is started to drive the separation frame 602 to rotate to separate the solid and liquid of the sludge. During the separation process, the separation rod 702 will rotate in the separation frame 602 in the opposite direction, and then during the solid-liquid centrifugal separation, the oil, water and solid particles in the sludge are broken up, and agglomerates are formed due to the strong interaction force, thereby reducing the viscosity of the sludge, increasing the fluidity of the sludge, and realizing the rapid solid-liquid separation of the oily sludge.

[0035] During the rotation, the cleaning rod 701 can continuously scrape the inner wall of the separation frame 602 to prevent sludge from clogging the mesh holes on the separation frame 602 and thus affecting the separation efficiency. The connecting frame 601 can continuously scrape the bottom surface of the top cover 2 to prevent sludge from adhering to the bottom surface of the top cover 2.

[0036] After separation is completed, the motor 3 can be turned off, the sedimentation tank can be placed below the liquid outlet 102, and the valve in the liquid outlet 102 can be opened to take out the separated liquid. After the liquid is precipitated in the sedimentation tank, the oil separation operation of the oily sludge can be completed.

[0037] Then, the motor 3 is turned on again, the container containing the solids is placed under the separation frame 602, and the valve is opened to collect the solids. At this time, the attachments on the bottom surface of the top cover 2 and the attachments on the side walls of the separation frame 602 will be continuously scraped off by the connecting frame 601 and the cleaning rod 701, thereby achieving the purpose of cleaning the inside of the separation frame 602 after use.
