Description

Technical Field

[0001] The present application relates to the technical field of oil recovery filtering devices, and in particular to an oil recovery filtering device. Background Art

[0002] Waste mineral oil is the oil that is replaced when it cannot be used anymore due to the change of its original physical and chemical properties caused by contamination by impurities, oxidation and heat. Waste mineral oil is very harmful. If it is discharged to the outside world at will, it will cause serious environmental pollution. Therefore, it is very important to properly handle waste mineral oil. The existing treatment of waste mineral oil is usually distillation. However, before distillation, because waste mineral oil often contains a lot of impurities such as mud and sand, filtering the waste mineral oil is an indispensable process.

[0003] The existing filtering method is to install a filter barrel in the device so that impurities are filtered in the filter barrel. Since some impurities adhere to the filter barrel, the filter holes on the filter barrel will be blocked by the impurities, affecting the efficiency of filtering impurities. Utility Model Content

[0004] The purpose of the present application is to provide a recovered oil filtering device in order to reduce the clogging of impurities in the filter holes of the filter barrel.

[0005] An oil recovery filter device provided in the present application adopts the following technical solution: it includes a valve body, the valve body is provided with a accommodating cavity, the valve body is detachably connected to a valve cover for covering the accommodating cavity, the valve body is provided with an oil inlet channel and an oil outlet channel connected to the accommodating cavity, a filter barrel is connected in the accommodating cavity, the filter barrel is provided with a plurality of filter holes, the valve body is connected to a water inlet pipe, the water inlet pipe is connected to an annular pipe, the annular pipe surrounds the filter barrel, the annular pipe is connected to a plurality of water spray pipes facing the filter barrel, the bottom of the valve body is connected to a water outlet pipe connected to the accommodating cavity, and the water outlet pipe is connected to a control valve for controlling the on and off of the water outlet pipe.

[0006] By adopting the above technical solution, waste mineral oil enters the filter barrel from the oil inlet channel, passes through the filter holes and is discharged from the oil outlet channel. When impurities block most of the filter holes, the initial channel is closed so that the waste mineral oil is no longer transported to the oil inlet channel, and the filtered waste mineral oil is discharged from the oil outlet channel. The control valve controls the water outlet pipe to open, and the water in the water inlet pipe injects water into the annular pipe. The water in the annular pipe is sprayed out from the water spray pipe, and the water impacts the impurities in the filter holes, reducing the impurities blocking the filter holes, thereby improving the filtering effect of the filter barrel.

[0007] Optionally, each of the water spray pipes is connected to a perforated plate, and the perforated plate is provided with a plurality of water spray holes.

[0008] By adopting the above technical solution, the aperture of the water spray hole is smaller than the aperture of the water spray pipe. When water passes through the water spray hole, it is subjected to a stronger fluid dynamic effect, forming a higher-speed liquid jet, thereby improving the effect of water impacting impurities in the filter hole, thereby reducing the clogging of the filter hole by impurities.

[0009] Optionally, the filter hole is inclined, the water inlet of the filter hole is located between the water outlet of the filter hole and the water outlet pipe, the water spray pipe is inclined, and the inclination direction of the water spray pipe is the same as the inclination direction of the filter hole.

[0010] By adopting the above technical solution, the filter holes are arranged at an angle, and impurities are not easily accumulated in the filter holes due to the influence of gravity. In addition, water impacts the inclined filter holes, which makes it easier for water to drive the impurities in the filter holes to leave the filter holes, thereby reducing the accumulation of impurities in the filter holes.

[0011] Optionally, there are several annular tubes, and the several annular tubes are distributed along the length direction of the filter barrel, and each of the annular tubes is connected to the water inlet pipe.

[0012] By adopting the above technical solution, the water spray pipes on the multiple annular pipes can spray water towards the filter barrel at the same time, thereby improving the effect of water impacting the filter barrel and reducing the accumulation of impurities in the filter holes.

[0013] Optionally, the inner wall of the accommodating cavity is connected to a mounting plate, the mounting plate is provided with a mounting hole for the filter barrel to pass through, the filter barrel is connected to a convex ring, the mounting plate is provided with a groove for cooperating with the convex ring, and the groove is connected to the mounting hole.

[0014] By adopting the above technical solution, when installing the filter barrel, the filter barrel is passed through the mounting hole, and the mounting hole provides space for the installation of the filter barrel until the convex ring is inserted into the groove, and the outer surface of the convex ring fits with the inner wall of the groove. The inner wall of the groove restricts the movement of the convex ring, that is, restricts the movement of the filter barrel, thereby improving the stability of the filter barrel installed on the mounting plate.

[0015] Optionally, the filter barrel is connected to a handle.

[0016] By adopting the above technical solution, when a large amount of impurities are accumulated in the filter barrel, the cover plate is removed from the valve body, and the filter barrel can be removed from the mounting plate through the handle, thereby improving the disassembly efficiency of the filter barrel.

[0017] Optionally, the filter barrel includes a first side plate and a second side plate, the first side plate is connected to a bottom plate, the filter holes are arranged on the first side plate, the second side plate and the bottom plate, and the first side plate and the second side plate are connected by a locking member.

[0018] By adopting the above technical solution, after the filter barrel is removed from the mounting plate, the locking member is loosened to separate the first side plate from the second side plate, which facilitates cleaning of impurities in the filter barrel, helps reduce the difficulty of cleaning the first side plate and the second side plate, and improves the cleaning efficiency. After the first side plate and the second side plate are cleaned, the first side plate and the second side plate are fixed together by the locking member, so that the first side plate, the second side plate and the bottom plate are spliced ​​into the filter barrel.

[0019] Optionally, the first side plate is connected to two sliding blocks, and the second side plate is provided with sliding grooves for cooperating with the corresponding sliding blocks.

[0020] By adopting the above technical solution, when installing the first side panel and the second side panel, the slider is inserted into the slide groove, the outer surface of the slider fits with the inner wall of the slide groove, and the inner wall of the slide groove restricts the movement of the slider, thereby improving the installation efficiency of the first side panel and the second side panel.

[0021] Optionally, each of the sliding connections has a limiting block, and the second side plate is provided with a limiting groove for cooperating with the corresponding limiting block, and the limiting groove is connected to the sliding groove.

[0022] By adopting the above technical solution, when installing the first side panel and the second side panel, the slider slides along the slide groove, and the limiting block cooperates with the sliding of the limiting groove to guide and limit the sliding of the second side panel, thereby improving the sliding stability of the second side panel, preventing the second side panel from separating from the first side panel during the sliding process, and improving the installation efficiency of the first side panel and the second side panel.

[0023] Optionally, the second side plate is connected to a positioning block, and the bottom plate is provided with a positioning groove for cooperating with the positioning block.

[0024] By adopting the above technical solution, when installing the first side plate and the second side plate, the positioning block is inserted into the positioning groove, and the outer surface of the positioning block fits with the inner wall of the positioning groove. The inner wall of the positioning groove limits the movement of the positioning block, thereby improving the stability of the second side plate compared to the bottom plate, and improving the stability of the overall structure of the filter barrel.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The water inlet pipe injects water into the annular pipe, and the water in the annular pipe is sprayed out from the spray pipe. The water impacts the impurities in the filter holes, reducing the clogging of the filter holes by impurities, thereby improving the filtering effect of the filter barrel.

[0027] 2. The filter holes are set at an angle, and impurities are not easily accumulated in the filter holes due to the influence of gravity. In addition, the water impacts the filter holes set at an angle, which makes it easier for water to drive the impurities in the filter holes out of the filter holes, thereby reducing the accumulation of impurities in the filter holes.
