Description

Technical Field

[0001] This utility model belongs to the field of oil filtration technology, and more specifically, it relates to a magnetic filtration device with a backwash structure. Background Technology

[0002] A magnetic filter, also known as a magnetic separator or magnetic separator, is a physical purification device that uses the magnetic force generated by a high-intensity magnetic field to continuously and efficiently adsorb and remove ferromagnetic impurities (such as iron filings, iron powder, and abrasives) from flowing liquids (especially oils) or gases.

[0003] Based on existing technology, it has been found that when existing filter devices are used for a long time, the filter element will accumulate a large amount of metal impurities such as iron filings on its surface. If not cleaned in time, it will easily become clogged, affecting the subsequent oil filtration. The traditional method is to clean it by disassembling the filter element, which requires repeated installation. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a magnetic suction filter device with a backwash structure. This solves the problem that when the filter element is used for a long time, a large amount of metal impurities such as iron filings are adsorbed on the surface of the filter element. If not cleaned in time, it is easy to cause blockage and affect the subsequent oil filtration. The traditional method is to disassemble the filter element for cleaning, which requires repeated installation of the filter element.

Then, the collection component can be pulled out and the waste on its inner wall can be processed. Attached Figure Description

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0018] Example: As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a magnetic suction filter device with a backwash structure, including a storage mechanism 1, a filtering mechanism 2, a collection mechanism 3, and a cleaning mechanism 4; The storage mechanism 1 is equipped with a filter mechanism 2; the collection mechanism 3 is installed on the storage mechanism 1; and the cleaning mechanism 4 is installed on the storage mechanism 1. The storage mechanism 1 includes: a main body 101, which is the filter device body; a cover plate 102 is provided on the top of the main body 101; and a mounting component 103 is provided at the bottom of the interior of the main body 101. The main body 101 is used to install the filter component 201 through the internal mounting component 103. The threaded hole provided in the mounting component 103 is adapted to the thread on the bottom of the filter component 201 for installation. This is a conventional connection method. The filter mechanism 2 includes: a filter element 201, which is connected to the mounting component 103 via a bottom thread; an electromagnetic column 202 is provided on the filter element 201; the filter element 201 is used to filter oil, while the electromagnetic column 202 is used to adsorb iron filings contained in the oil. The electromagnetic column 202 is installed on the inner wall of the filter element 201, which can stably adsorb iron filings on the filter element 201. The magnetic field of the electromagnetic column 202 directly penetrates its outer filter medium. The iron filings are first mechanically intercepted by the filter medium, and then firmly "locked" on the surface of the medium by the strong magnetic field below, preventing them from falling off or penetrating. When it is energized, it generates magnetism, which can adsorb iron filings. When it is de-energized, it loses magnetism, causing most of the iron filings to fall off. This is prior art known to those skilled in the art. The connection with the external cable is a conventional installation method of the electromagnetic column 202 in the art. The cleaning mechanism 4 includes: a cylinder 401, which is fixedly mounted on the cover plate 102; a flow element 402 is provided at the top of the cylinder 401; a steel pipe 403 is provided at the bottom of the flow element 402; and a nozzle 404 is provided at the bottom of the steel pipe 403. The cylinder 401 is used to extend and retract via a control panel to move the flow element 402 up and down. The steel pipe 403 is used to install the nozzle 404 to deliver compressed air. The flow element 402 is connected to an air compressor via a hose, and the air compressor delivers compressed explosion-proof gas. The air compressor is equipped with a switch to control the delivery of compressed air. This is an existing device in the field and will not be described in detail. The pressure of the compressed gas is greater than the attraction force of the electromagnetic column 202, so it can clean up iron filings.

[0019] Among them, such as Figure 2 As shown, the main body 101 has an inlet on the top side; the main body 101 has an outlet at the bottom; a control valve is provided on the outlet of the main body 101; a threaded hole is provided in the middle of the mounting part 103; the main body 101 draws oil in through an external oil pump connected to the inlet, which is a conventional operation in the field; the outlet is controlled by a control valve, which is a ball valve, a common valve control.

[0020] Among them, such as Figure 3 As shown, the filter element 201 has a round hole; the bottom of the filter element 201 has a discharge port; the discharge port on the filter element 201 corresponds to the threaded hole on the mounting part 103; the discharge port at the bottom of the filter element 201 and the threaded hole of the mounting part 103 are connected to ensure that the filtered oil is discharged; the round hole on the filter element 201 is much smaller than the size of the iron filings and will not allow the iron filings to pass through.

[0021] Among them, such as Figure 3As shown, the collection mechanism 3 includes: a collection component 301 and a pull rod 302; the collection component 301 is mounted on the mounting component 103; the collection component 301 is slidably mounted on the bottom of the filter element 201; the distance between the side of the collection component 301 and the filter element 201 is set to 0.1-0.5mm; the pull rod 302 is fixedly mounted on the collection component 301; the collection component 301 here is used to collect waste debris. The collection component 301 here has a large weight and will not float, so it will not affect the filtration of oil. Furthermore, it can be pulled out by the pull rod 302, which allows for a secondary cleaning of the filter element 201.

[0022] Among them, such as Figure 4 As shown, a flexible hose is provided on the side of the flow element 402; the steel pipe 403 is made of stainless steel; the steel pipe 403 is slidably mounted on the cover plate 102; the nozzle 404 is a flat nozzle; the tilt angle of the nozzle 404 is set to 15°-45°; the nozzle 404 here is used to make the spraying range larger by setting it to a flat nozzle, and by using multiple sets of nozzles 404 together, compressed gas can be released to various positions of the filter element 201, thereby blowing away iron filings.

[0023] Among them, such as Figure 4 As shown, the cleaning mechanism 4 also includes: a scraper 405; the inner wall of the scraper 405 is set with an inclined structure; the scraper 405 is fixedly mounted on the steel pipe 403; the distance between the inner wall of the scraper 405 and the filter element 201 is set to 0.1-0.5mm; the scraper 405 is made of engineering plastic; the scraper 405 here is used to assist in scraping the outer wall of the filter element 201 by contacting it, thereby enhancing the cleaning effect.

[0024] In another embodiment, the cylinder 401 here can also be replaced by an electric telescopic rod, and compressed air jetting can also replace other high-pressure fluids for jetting, achieving the same back-blowing cleaning effect.

[0025] The specific usage and function of this embodiment are as follows: In this invention, when using the device, oil enters the main body 101 through an oil pump, and the electromagnetic column 202, when energized, generates suction to attract iron filings inside the oil. The pure oil flows through the filter element 201, while impurities are blocked externally and discharged through the bottom outlet and the main body 101's outlet, thus achieving filtration. During cleaning, by closing the external oil pump and the control valve at the bottom of the main body 101, the control cylinder 401 extends and retracts, causing the flow element 402 and steel pipe 403 to move up and down. The flow element 402 is connected to an external air compressor via a side hose, through which high-pressure explosion-proof gas is input. The explosion-proof gas is then sprayed through the nozzle 404. When the electromagnetic column 202 is not energized, it loses its magnetism and is blown down by the jet. The scraper 405 is moved by the steel pipe 403, which assists in scraping away the iron filings, thus achieving a backflushing cleaning effect. The cleaned iron filings and other impurities fall into the collection member 301 for collection. At this time, the cover plate 102 is removed, and the pull rod 302 is pulled manually. The pull rod 302 moves the collection member 301. As the collection member 301 is pulled upward, it comes into contact with the surface of the filter element 201, which can scrape away the iron filings on the surface of the filter element 201 a second time. At this time, the collection member 301 can be pulled out and the waste on its inner wall can be processed.
