Description

Technical Field

[0001] The utility model relates to the technical field of petroleum filtering, in particular to a slag removal filtering device for petroleum mining. Background Art

[0002] Oil extraction requires oil filtration**. During the oil extraction and processing process, various impurities and pollutants will be generated, including suspended matter, moisture, salt, heavy metals, etc. In order to ensure the quality and purity of the oil, it needs to go through a series of filtration and separation processes to remove these impurities and pollutants. Filtration technology is a commonly used method for separating insoluble solid impurities from oil. This is mainly achieved by using porous media, which can effectively remove oil and suspended matter from wastewater through wetting and collision agglomeration. In addition, there are other methods such as membrane separation technology and chemical methods for filtering and separating oil. Therefore, oil does need to be filtered during oil extraction to ensure its quality and purity.

[0003] According to a Chinese patent application number 202321708217.9, a slag filtering device for oil mining uses multiple filters to filter the oil during use. However, when impurities need to be cleaned after filtration, the entire equipment needs to be shut down and normal filtering work cannot be performed. Therefore, an improved slag filtering device for oil mining is needed to address this problem. Utility Model Content

[0006] Preferably, a slag discharge port is provided at the upper end of one side of the shell surface, and the shell and the filter bin are arranged obliquely. Through the inclined shell and the filter bin, a guide plate is fixedly provided on the shell surface at one side of the slag discharge port, so that impurities filtered out from the filter bin can slide into the shell under the action of the downward force, and the impurities inside the shell can be discharged through the slag discharge port; finally, it is guided into the predetermined position through the guide plate.

[0007] Preferably, an eccentric counterweight is movably provided on the shell surface at the lower end of the motor through a rotating shaft, and the output shaft end of the motor is transmission-connected to the rotating shaft where the eccentric counterweight is located through a belt and a pulley.

[0008] Preferably, a hose is provided in the middle of the connecting pipe. Since the device will vibrate when in use to ensure that impurities can enter the shell along the inclined filter bin, in order to avoid vibration affecting the pipeline connected to the device, the middle part of the connecting pipe is specially selected as a hose.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] According to the utility model, the oil inside the filter bin can leak out through the first through hole, while the impurities will remain inside the filter bin, and at this time, since the shell and the filter bin are inclined, the impurities filtered out from the filter bin can eventually enter the shell under the action of the downward force, and at this time, the rotating drum and the scraper are driven by the motor to rotate, and the continuously rotating scraper can drive the impurities deposited on the lower end of the shell to move upward, and then the impurities driven to the upper end of the shell by the rotating scraper can be aligned with the slag discharge port, and at this time, these impurities can eventually be discharged from the slag discharge port under the action of the downward force, so that the device can filter the oil while discharging slag, and in addition to maintenance, the entire device does not need to be shut down for slag discharge, and the oil filtering work can be continuously performed, thereby improving the use effect of the device.

[0013] The utility model has a slag discharge requirement when in use; and the slag discharge power of the device mainly relies on the sliding force to discharge the slag, so that the device can drive the eccentric counterweight block to rotate when in use, thereby driving the device as a whole to vibrate, thereby improving the slag discharge effect.

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.

[0020] See also Figure 1-4 The utility model provides a technical solution: a slag filtering device for oil mining, comprising a connecting pipe 1, a filtering mechanism for filtering oil is arranged at the lower end of the connecting pipe 1, the filtering mechanism comprises a filtering bin 2, a shell 3, a rotating drum 4, a scraper 5, and a motor 6, the filtering bin 2 is fixedly arranged at the lower end of the connecting pipe 1, a shell 3 is fixedly arranged on one side of the surface of the filtering bin 2, a rotating drum 4 is movably arranged on the middle part of the inner side of the shell 3 through a rotating shaft, a scraper 5 is fixedly arranged on the outer surface of the rotating drum 4, a motor 6 is fixedly arranged on one side of the surface of the shell 3 through a mounting seat, and the output shaft end of the motor 6 is transmission-connected to the rotating shaft of the rotating drum 4 through a coupling, so that the motor 6 can drive the rotating drum 4 to rotate.

[0021] A slag discharge port 7 is arranged at the upper end of one side of the surface of the shell 3. The shell 3 and the filter bin 2 are arranged obliquely. Through the inclined shell 3 and the filter bin 2, a guide plate 8 is fixedly arranged on the surface of the shell 3 at one side of the slag discharge port 7, so that the impurities filtered out of the filter bin 2 can slide down into the shell 3 under the action of the downward force, and the impurities in the shell 3 can be discharged through the slag discharge port 7; and finally guided into the predetermined position by the guide plate 8;

[0022] The surface of the housing 3 is provided with an eccentric counterweight 9 at the lower end of the motor 6 through a rotating shaft. The output shaft end of the motor 6 is connected to the rotating shaft where the eccentric counterweight 9 is located through a belt and a pulley. Since the device also needs to discharge slag when in use, and the slag discharge power of the device mainly relies on the downward force to discharge slag, the device can drive the eccentric counterweight 9 to rotate when in use, thereby driving the device as a whole to vibrate, thereby improving the slag discharge effect.

[0023] A hose 10 is provided in the middle of the connecting pipe 1. Since the device will vibrate when in use to ensure that impurities can enter the housing 3 along the inclined filter bin 2, in order to prevent the vibration from affecting the pipeline connected to the device, the middle part of the connecting pipe 1 is specially selected as a hose 10;

[0024] The upper end of the connecting pipe 1 is fixedly provided with a connecting flange 11, through which the connecting pipe 1 can be conveniently connected to other pipelines or equipment;

[0025] A plurality of first through holes 12 are evenly formed on the surface of the filter bin 2, and a plurality of second through holes 13 are formed on the outer surface of the scraper 5. The first through holes 12 of the device are used to filter impurities, so that oil can flow out through the filter bin 2; impurities will remain inside the filter bin 2 and will gradually enter the shell 3 under the influence of the sliding force; and the second through holes 13 are used to filter the oil, so that the rotation of the scraper 5 will not drive the oil upward, but will only drive the impurities upward; it should be noted that in order to prevent oil from being discharged from the slag discharge port 7 of the device, the oil inlet flow rate of the connecting pipe 1 should be controlled so that the liquid level inside the shell 3 is always maintained at about half the height.

[0026] Working principle: When using the device, the oil to be filtered can be guided to the inside of the filter bin 2 through the connecting pipe 1. At this time, the oil in the filter bin 2 can leak out through the first through hole 12, while the impurities will remain in the filter bin 2. At this time, the shell 3 and the filter bin 2 are tilted; the impurities filtered out of the filter bin 2 can eventually enter the shell 3 under the action of the downward force. At this time, the rotating drum 4 and the scraper 5 are driven by the motor 6 to rotate, and the continuously rotating scraper 5 can drive the impurities deposited at the lower end of the shell 3 to move upward. At this time, the oil can be filtered through the second through hole 13, so that the scraper 5 will not drive the oil upward when rotating; instead, it will only drive the impurities upward; then the impurities driven to the upper end of the shell 3 by the rotating scraper 5 can be aligned with the slag discharge port 7. At this time, under the action of the downward force, these impurities can eventually be discharged from the slag discharge port 7, so that the device can filter the oil while discharging slag. In this way, except for maintenance, the entire device does not need to be shut down for slag discharge, and the oil filtering work can be continuously performed, thereby improving the use effect of the device;

[0027] And the device has a slag discharge requirement when in use; and the slag discharge power of the device mainly relies on the sliding force to discharge the slag, so that the device can drive the eccentric counterweight block 9 to rotate when in use, thereby driving the device as a whole to vibrate, thereby improving the slag discharge effect;

[0028] It should be noted that when the device is in use, the oil inlet flow rate of the connecting pipe 1 should be controlled so that the liquid level inside the housing 3 is always maintained at about half the height.

[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
