Description

Technical Field

[0001] This utility model relates to the technical field of oil filtration equipment, and in particular to a pre-filtration equipment for oil extraction sand and gravel. Background Technology

[0002] After oil extraction, the sand and gravel carried in the pipeline will cause a sudden increase in the density of the fluid due to solid-state collisions. This will cause the gas trapped in the fluid to form oil bubbles. During transportation, the oil bubbles are prone to sticking and splashing into the transportation pipeline, causing oil residue to accumulate and settle, resulting in solid blockage of sand and gravel. This will affect the branching of the flow in the pipeline and auxiliary processing operations, interfere with the overall filtration fineness, and also cause oil stains to penetrate into the tank. This will cause oil film blockage, and the sand and gravel blockage will scratch and wear the inner wall of the pipeline and tank, slowing down the oil extraction and transportation. Therefore, it is necessary to pre-filter the sand and gravel in the oil.

[0003] However, existing oil pre-filtration equipment requires frequent replacement of the filter screen. Otherwise, the amount of sand and gravel filtered will easily cause oil blockage. Moreover, after long-term use, a large amount of oil dirt will adhere to the surface of the filter screen, affecting the filtration and oil transportation efficiency. In the past, the filter screen was replaced and cleaned manually, which was very troublesome and could not be automatically replaced and cleaned. Therefore, an oil extraction sand and gravel pre-filtration equipment is provided. Utility Model Content

[0019] Example: Reference Figure 1-4 The invention discloses a pre-filtration device for oil extraction sand and gravel, comprising: a filter box 1, the interior of which includes a filter chamber 101, and a limiting member 104 on one side of the filter chamber 101; a storage box 2, the interior of which includes a storage bin 201, and a storage drawer 202 at the bottom of the storage bin 201; a filter assembly 3, which includes a baffle 301 installed on one side of the storage box 2, a filter screen 302, and a first motor 303, the first motor 303 being used to drive the filter screen 302 to rotate; and a cleaning assembly 4, which includes a cleaning rack 401 installed in the storage box 2, a nozzle assembly 402, and a second motor 403. This invention allows for the replacement of the filter screen 302 via the filter assembly 3, while simultaneously allowing sand and gravel to be poured into the storage box 2. The cleaning assembly 4 is used to rinse the filter screen 302, making it suitable for oil pre-filtration.

[0020] With the above structure: an oil inlet 102 is provided on the upper side of one side of the filter chamber 101, and an oil outlet 103 is provided on the lower side of one side of the filter chamber 101. The limiting member 104 is connected to the filter box 1 by a torsion spring. The limiting member 104 is in contact with the filter screen 302. When the filter screen 302 rotates, it can squeeze the limiting member 104 from below, causing the limiting member to rotate. When the filter screen 302 reaches the designated position, the limiting member returns to its original position, supporting the filter screen 302 from below, which facilitates the support of the filter screen 302 when the oil passes through it.

[0021] With the above structure, the storage box 2 is sealed and fixedly connected to the filter box 1, and the storage drawer 202 is sleeved with the storage box 2, which facilitates the collection of sand and gravel.

[0022] With the above structure: the filter screen 302 is located on both sides of the baffle 301, the shaft of the first motor 303 is connected to one side of the baffle 301, the baffle 301 is connected to the storage box 2 by a bearing, the filter screen 302 is bolted to the baffle 301, and the first motor 303 is bolted to the storage box 2. The first motor 303 is a geared motor, which is convenient to drive the filter screen 302 to rotate, thereby changing the filter screen 302.

[0023] With the above structure: the cleaning frame 401 is located above the storage bin 201, the nozzle assembly 402 is installed on one side of the cleaning frame 401, the shaft of the second motor 403 is connected to one end of the cleaning frame 401, the cleaning frame 401 is connected to the storage box 2 by a bearing, the second motor 403 is bolted to the storage box 2, the nozzle assembly 402 is connected to the external water pipe valve, and the second motor 403 is a geared motor, which is convenient for swing rinsing operation.

[0024] The working principle of this embodiment is as follows: The oil inlet 102 and the oil outlet 103 are connected to the oil pipeline. After the oil enters the filter chamber 101, it is filtered by the filter screen to remove sand and gravel. The filtered oil is discharged through the oil outlet 103. When there is a lot of sand and gravel after long-term filtration, the first motor 303 drives the baffle 301 to rotate, rotating the working filter screen into the storage chamber 201. At this time, the filter screen is facing downwards, and the filtered sand and gravel are poured into the storage drawer 202. At the same time, the filter screen on the other side rotates into the filter chamber 101 to continuously filter the oil. The limiting member 104 supports the filter screen, so there is no need to manually replace the filter screen. The storage drawer 202 can be pulled out for cleaning later. It not only has the effect of automatically replacing the filter screen, but also has the effect of cleaning sand and gravel. After long-term use, oil dirt will adhere to the filter screen. At this time, high-pressure water can be sprayed onto the filter screen through the nozzle group 402, and the second motor 403 drives the cleaning frame 401 to rotate and adjust the rinsing angle to wash away the oil dirt on the filter screen, thus achieving the effect of automatically cleaning the filter screen.

[0025] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
