Description

Technical Field

[0001] The utility model relates to the technical field of oil extraction, in particular to a filtering separator for oil extraction. Background Technique

[0002] During the oil extraction process, since the extracted oil contains impurities such as sand and gravel, which affect the quality and use of the oil, a filtering device is required to filter the oil. For example, in a filtering device for oil extraction (patent number: CN202223492684.0) disclosed in Chinese patent literature, the semi-gear rotates, causing the rack to push the filter screen frame downward, so that the spikes pass through the filter screen frame, preventing the filtered oil impurities from accumulating on the filter screen frame. However, the spikes only push the impurities, temporarily preventing them from accumulating, but the impurities still remain on the top of the filter screen frame, reducing the filtering efficiency of the oil. Moreover, in the above device, it is necessary to disassemble the filter screen frame to clean the filtered impurities. Disassembling and installing the grid frame not only takes time and effort but also reduces the filtering efficiency of the filtering device for oil.

[0003] Therefore, we propose a filtering separator for oil extraction. Content of the Utility Model

[0004] The purpose of the utility model is to provide a filtering separator for oil extraction to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A filtering separator for oil extraction, including a filter housing, an oil inlet pipe is arranged at the top of the filter housing, an oil outlet pipe is arranged at the bottom of the filter housing, valves are arranged on both the oil inlet pipe and the oil outlet pipe, a fixing rod is arranged on the upper part of the inner wall of the filter housing, a V-shaped plate is arranged on the fixing rod, a filter plate is arranged in the middle of the filter housing, a liquid level gauge is arranged at the lower right part of the filter housing, sand discharge ports are arranged in the middle of both the left and right sides of the filter housing, one end of each sand discharge port is connected to a sand discharge pipe, a threaded sleeve is arranged on the sand discharge pipe, a nut is arranged at one end of the threaded sleeve, and a sealing gasket is arranged between the right end of the sand discharge pipe and the threaded sleeve.

[0006] Preferably, the V-shaped plate is fixedly installed on the fixing rod, and the V-shaped plate is directly below the oil inlet pipe.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figure 1-2, the present utility model provides a technical solution: an oil extraction filter separator, including a filter housing 1, an oil inlet pipe 2 is arranged at the top of the filter housing 1, an oil outlet pipe 3 is arranged at the bottom of the filter housing 1, valves 4 are arranged on both the oil inlet pipe 2 and the oil outlet pipe 3, a fixing rod 5 is arranged at the upper part of the inner wall of the filter housing 1, a V-shaped plate 6 is arranged on the fixing rod 5, a filter plate 7 is arranged in the middle of the filter housing 1, a liquid level gauge 8 is arranged at the lower right part of the filter housing 1, sand discharge ports 9 are arranged in the middle of both the left and right sides of the filter housing 1, one end of the sand discharge port 9 is connected to a sand discharge pipe 10, a threaded sleeve 11 is arranged on the sand discharge pipe 10, a nut 12 is arranged at one end of the threaded sleeve 11, and a sealing gasket 13 is arranged between the right end of the sand discharge pipe 10 and the threaded sleeve 11. When the extracted oil enters the filter housing 1 through the oil inlet pipe 2, the V-shaped plate 6 diverts the oil, causing the oil to flow to both sides of the V-shaped plate 6 and reach both sides of the filter housing 1, and then passes through the filter plate 7 for filtration. The filter plate 7 is set to be arc-shaped. After the filter plate 7 filters the oil, the filtered sand accumulates at both ends of the filter plate 7, and the middle part of the filter plate 7 can still filter the oil. When the valve 4 on the oil inlet pipe 2 is closed and the oil inlet stops, the liquid level height of the oil in the filter housing 1 is observed through the liquid level gauge 8. By using a tool to rotate the nut 12, the nut 12 drives the threaded sleeve 11 to rotate, and the threaded sleeve 11 is removed. Both the sand discharge port 9 and the sand discharge pipe 10 are inclined. The filtered sand is discharged through the sand discharge port 9 and the sand discharge pipe 10. Without disassembling the filter plate 7, the sand discharge work is carried out, effectively improving the sand discharge speed, and thus improving the filtration efficiency of the device for oil.

[0018] Among them, the V-shaped plate 6 is fixedly installed on the fixing rod 5, the V-shaped plate 6 is directly below the oil inlet pipe 2, and the V-shaped plate 6 diverts the oil, so that

[0019] The filter plate 7 is set to be arc-shaped. The oil flows to both ends of the filter plate 7 through both ends of the V-shaped plate 6 for filtering the oil, so that the filtered sand is at both ends of the filter plate 7. The filter plate 7 is set to be arc-shaped and convex upward in the middle. The filter plate 7 can still filter the oil and will not affect the filtration of the oil by the filter plate 7;

[0020] The sand discharge port 9 is inclined. The left end of the bottom of the sand discharge port 9 is flush with the top of the right end of the filter plate 7. The sand discharge port 9 and the sand discharge pipe 10 are inclined, so that the filtered sand is discharged through the sand discharge port 9 and the sand discharge pipe 10 under the action of gravity.

[0021] The surface of the sand discharge pipe 10 is provided with external threads that match the threaded sleeve 11. The nut 12 is fixedly connected to the threaded sleeve 11. By using a tool (such as a wrench) to rotate the nut 12, the nut 12 drives the threaded sleeve 11 to rotate. The threaded sleeve 11 is matched with the external threads provided on the surface of the sand discharge pipe 10 to complete the installation and disassembly of the threaded sleeve 11.

[0022] Working principle: After the petroleum enters the filter housing 1 through the inlet pipe 2, the V-shaped plate 6 diverts the petroleum, causing the petroleum to flow to both sides of the V-shaped plate 6 and reach both sides of the filter housing 1. Then it is filtered by the filter plate 7. The filter plate 7 is set in an arc shape. After the filter plate 7 filters the petroleum, the filtered sand and gravel accumulate at both ends of the filter plate 7, and the middle part of the filter plate 7 can still filter the petroleum. When the valve 4 on the inlet pipe 2 is closed to stop the oil inlet, the liquid level height of the petroleum in the filter housing 1 is observed through the liquid level gauge 8. By using a tool to rotate the nut 12, the nut 12 drives the threaded sleeve 11 to rotate, and the threaded sleeve 11 is removed. The sand discharge port 9 and the sand discharge pipe 10 are both inclined. The filtered sand and gravel are discharged through the sand discharge port 9 and the sand discharge pipe 10. Without disassembling the filter plate 7, the sand discharge work is carried out, effectively improving the sand discharge speed, and thus improving the filtration efficiency of the device for petroleum.

[0023] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
