An ultrasonic focusing probe is mounted on the top of the housing, and multiple ultrasonic transducers are mounted on the bottom. The ultrasonic focusing probe can be adjusted in range via a rotatable universal movable bracket to enhance its effectiveness. Furthermore, the ultrasonic frequency, power, and action time of the ultrasonic focusing probe and ultrasonic transducer are independently and continuously adjustable via an ultrasonic generator.

While this device solves the aforementioned problems, it still presents the problem of difficulty in cleaning impurities that have settled in the tank, which can easily cause clogging of the device. Therefore, an ultrasonic desilting and deoiling device is proposed to address the aforementioned issues. Summary of the Invention

When the device is in operation, crude oil enters the device from the feed pipe, and the heating tube is started to heat the crude oil to reduce the viscosity of the crude oil and precipitate and separate the impurities in the crude oil. At this time, the water and impurities contained in the crude oil are ionized by the ionization mechanism to separate the layers, and the crude oil is filtered and separated by the oil filter plate to the top of the electric desalting tank. The impurities and water will be separated by the oil filter plate at the bottom of the oil filter plate, and then the crude oil will be extracted and collected by the oil suction device and transported to the interior of the finished oil tank through the guidance of the oil pipeline. The impurities and water at the bottom of the oil filter plate will be discharged through the pump pipe. At this time, the motor is started to drive the reciprocating screw rod to rotate, and the reciprocating screw rod rotates while driving the traverse rod to rotate through the pulley group. The rotation of the rod drives the reciprocating screw rod 2 to rotate through the pulley group. While the reciprocating screw rod 2 rotates, it drives the slag pushing rod to move back and forth through the cross spiral groove on the outer circumference and the limit of the electric desalter. The reciprocating movement of the slag pushing rod drives the reciprocating movement of the fixed cross frame. The reciprocating movement of the fixed cross frame drives the reciprocating movement of the ultrasonic tube, thereby increasing the contact area between the ultrasonic tube and the bottom impurities and improving the efficiency of cleaning impurities. The reciprocating movement of the ultrasonic tube vibrates and separates the impurities inside the electric desalter. Then the slag pushing rod reciprocates to push the vibrated impurities to be collected near the pump pipe, and then the pump pipe is started to suck the impurities out of the device. This process avoids the problem of impurities generated during crude oil ionization adhering to the inner wall of the device and being difficult to clean, thereby saving the cost of subsequent manual cleaning of the device.Improves the operating efficiency of the device. Crude oil contains a lot of impurities when it is not filtered. To facilitate the transportation of crude oil, the feed agitator rotates by rotating the traverse rod, thereby clearing and transporting the unfiltered crude oil inside the feed pipe, preventing crude oil from clogging inside the feed pipe and affecting the operation of the device.

The reciprocating movement of the moving device frame drives the hollow moving frame to reciprocate, and the reciprocating movement of the hollow moving frame drives the ionization rod to reciprocate. When the ionization rod is started and moves back and forth, the crude oil is ionized, thereby promoting the separation and purification of the crude oil. The hollow movable frame stirs the crude oil in the device while moving back and forth, thereby increasing the ionization area of ​​the ionization rod for the crude oil and improving the ionization efficiency of the crude oil. At the same time, the movable device frame drives the conical protrusion to move back and forth while moving back and forth.

At this time, the water will flow into the interior of the drainage tank through the filtration of the filter screen, thereby separating the separated impurities and water, which facilitates the subsequent treatment of impurities. At this time, the motor is started to drive the reciprocating screw to rotate three times through the cross-type spiral grooves on the outer circumference and the limit of the inner wall of the bottom of the drainage tank to drive the movable block to move back and forth. The movable block drives the water pusher plate to move back and forth at the same time.

The ultrasonic tube reciprocates to shake off and separate the impurities inside the electric desalter. Then the slag pusher reciprocates to push the shaken impurities to the vicinity of the pump pipe, and then the pump pipe is started to suck the impurities out of the device.

This process avoids the problem of impurities generated during crude oil ionization adhering to the inner wall of the device and being difficult to clean, thereby saving the cost of subsequent manual cleaning of the device and improving the operating efficiency of the device.

[0015] The ionization mechanism 5 includes a movable device frame 501, a fixed device rod 502, a hollow movable frame 503, an ionization rod 504, and a conical protrusion 505. The movable device frame 501 is movably connected to the outer circumferential surface of the reciprocating screw rod 3, the fixed device rod 502 is fixedly connected to the top of the movable device frame 501, the hollow movable frame 503 is fixedly connected to the top of the fixed device rod 502, the ionization rod 504 is fixedly connected to the inner wall of the hollow movable frame 503, and the conical protrusion 505 is fixedly connected to the bottom of the hollow movable frame 503. The ionization mechanism 5 also includes a slide bar 506, a transmission drive wheel 507, a fixed spring disc 508, and an oil swing plate 509. The slide bar 506 is slidably connected to the inner wall of the feed pipe 409, and the transmission drive wheel 507 is rotatably connected to the inner wall of the slide bar 506. The fixed spring disc 508 is fixedly connected to the outer circumference of the slide rod 506, the oil swing plate 509 is fixedly connected to the bottom of the slide rod 506, the transmission drive wheel 507 is located on the movement trajectory of the conical protrusion 505, and the fixed spring disc 508 is connected to the feed pipe 409 by a spring. The ultrasonic silt removal and oil removal device, under the mutual cooperation of the conical protrusion 505, the drive wheel 507, and the feed pipe 409, makes the conical protrusion 505 move back and forth while contacting and squeezing the transmission drive wheel 507. The transmission drive wheel 507 is squeezed and stretched by the spring between the fixed spring disc 508 and the feed pipe 409, and at the same time drives the oil swing plate 509 to move downward to flip and stir the crude oil in the heating process at the bottom of the device, thereby accelerating the heating speed of the crude oil and improving its crude oil filtration production efficiency.

[0016] Working principle: When the device is in operation, crude oil enters the device from the feed pipe 409, the heating pipe 401 is started to heat the crude oil to reduce the viscosity of the crude oil, and the impurities in the crude oil are precipitated and separated. At this time, the water and impurities contained in the crude oil are separated by ionization of the ionization mechanism 5. The crude oil is filtered and separated by the oil filter plate 405 to the top of the electric desalting tank 1. The impurities and water will be separated by the oil filter plate 405 at the bottom of the oil filter plate 405. The crude oil will then be extracted and collected by the oil suction device 8 through the transmission The oil pipe 7 is guided to transport it to the interior of the finished oil tank 2, and the impurities and water at the bottom of the oil filter plate 405 will be discharged through the pump pipe 609. At this time, the motor is started to drive the reciprocating screw rod 3 to rotate. While the reciprocating screw rod 3 rotates, it drives the traverse rod 403 to rotate through the pulley group. The rotation of the traverse rod 403 drives the reciprocating screw rod 2 404 to rotate through the pulley group. While the reciprocating screw rod 2 404 rotates, it drives the slag pushing rod 406 to move back and forth through the cross spiral groove on the outer circumference and the limit of the electric desalting tank 1. The reciprocating movement of the slag pushing rod 406 drives the fixed cross frame 407 to move back and forth, and the reciprocating movement of the fixed cross frame 407 drives the reciprocating movement of the ultrasonic tube 408, thereby increasing the contact area between the ultrasonic tube 408 and the impurities at the bottom and improving the efficiency of cleaning impurities. The reciprocating movement of the ultrasonic tube 408 shakes off and separates the impurities inside the electric desalter 1. Then the slag pushing rod 406 moves back and forth to push the shaken impurities to be collected near the pump pipe 609, and then the pump pipe 609 is started to suck the impurities out of the device. This process avoids the problem of impurities generated during crude oil ionization adhering to the inner wall of the device and being difficult to clean, thereby saving the cost of subsequent manual cleaning of the device and improving the operating efficiency of the device. When the crude oil is not filtered, it contains a lot of impurities. In order to facilitate the transportation of the crude oil, the rotation of the traverse rod 403 drives the feeding stirrer 410 to rotate, thereby dredging and transporting the unfiltered crude oil inside the feed pipe 409, preventing the crude oil from being blocked inside the feed pipe 409 and affecting the operation of the device.

[0017] As the reciprocating screw 3 rotates, the cross-type spiral groove on the outer circumference drives the movable device frame 501 to move back and forth under the limit of the inner wall of the electric desalting tank 1. The reciprocating movement of the movable device frame 501 drives the hollow movable frame 503 to move back and forth, and the reciprocating movement of the hollow movable frame 503 drives the ionization rod 504 to move back and forth. At this time, the ionization rod 504 is started so that the crude oil is ionized during the reciprocating movement of the ionization rod 504, thereby promoting the separation and purification of the crude oil. The reciprocating movement of the hollow movable frame 503 stirs the crude oil in the device. Thereby, the ionization area of ​​the crude oil by the ionization rod 504 is increased, and the ionization efficiency of the crude oil is improved. At the same time, the reciprocating movement of the movable device frame 501 drives the conical protrusion 505 to move reciprocally. The conical protrusion 505 contacts and squeezes the transmission drive wheel 507 while moving back and forth. The transmission drive wheel 507 is squeezed and stretched, and the spring between the fixed spring disc 508 and the feed pipe 409 is stretched. At the same time, the oil turbulence plate 509 is driven to move downward to turn and stir the crude oil during the heating process at the bottom of the device, thereby accelerating the heating speed of the crude oil and improving the production efficiency of its crude oil filtration.

The residue processing mechanism 6 also includes a movable block 606, a water pushing plate 607, a vertical scraper 608, and a pump pipe 609. The movable block 606 is movably connected to the outer circumferential surface of the reciprocating screw rod 3 605, and the water pushing plate 607 is rotatably connected to the inner wall of the reciprocating screw rod 3 605 through a torsion spring. The inner wall of the movable block 606, the vertical scraper 608 is fixedly connected to the inner wall of the rotating block 604, the pump pipe 609 is fixedly connected to the bottom of the electric desalination tank 1, the reciprocating screw rod three 605 is located on the movement trajectory of the water pushing plate 607, the vertical scraper 608 is in contact with the inner wall of the filter screen 603, the water pushing plate 607 is in contact with the bottom inner wall of the drainage compartment 601, and a motor is provided on the left side of the reciprocating screw rod three 605. The filter screen 603 is fixedly connected to the bottom of the pump pipe 609. The ultrasonic silt removal and oil removal device, under the cooperation of the water pushing plate 607, the rotating block 604 and the vertical scraper 608, makes the water pushing plate 607 move back and forth while pushing out the residual water remaining on the bottom inner wall of the drainage compartment 601, thereby avoiding incomplete cleaning of the filtered water inside the drainage compartment 601 and producing residues.

[0019] Working principle: When the crude oil inside the device is extracted by the oil suction device 8, the device pump pipe 609 is started at this time. At this time, the water and impurities separated in the electric desalting tank 1 will be sucked into the interior of the drainage chamber 601 by the pump pipe 609. At this time, the water will be filtered through the filter 603 and flow into the interior of the drainage chamber 601, thereby separating the dissociated impurities and water, thereby facilitating the subsequent treatment of impurities. At this time, the motor is started to drive the reciprocating screw rod 3 605 to rotate through the cross spiral groove on the outer circumference and the limit of the inner wall of the bottom of the drainage chamber 601, driving the movable block 606 to move back and forth. The block 606 moves back and forth, and at the same time, the water pushing plate 607 is driven to move back and forth. When the water pushing plate 607 contacts the rotating block 604 during the movement, the friction between the outer wall of the water pushing plate 607 and the outer wall of the rotating block 604 drives the rotating block 604 to rotate, thereby driving the vertical scraper 608 to rotate, scraping and cleaning the inner wall of the filter screen 603 to prevent the filter screen 603 from being blocked and affecting the normal operation of the device. At the same time, the water pushing plate 607 moves back and forth, and the residual water remaining on the bottom inner wall of the drainage chamber 601 is pushed out, thereby avoiding incomplete cleaning of the filtered water inside the drainage chamber 601 and producing residue.
