Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a magnetic basket filter. Background Technology

[0002] A filter is a device used to separate impurities from liquids or gases. It is widely used in pipeline systems in industries such as petroleum, chemical, pharmaceutical, food, and environmental protection. Its basic working principle is to use a filter screen or filter medium to trap solid particles, suspended matter, or other impurities in the fluid, thereby ensuring the normal operation of subsequent process equipment and the stability of product quality.

[0003] Existing basket filters can only intercept non-magnetic solid particles and cannot effectively remove ferromagnetic impurities such as iron filings and rust from fluids. While magnetic filters can adsorb ferromagnetic impurities, they are powerless against non-magnetic particles. Moreover, cleaning them usually requires stopping the machine for disassembly, which is cumbersome and affects production efficiency. Although some combined filters have dual filtration functions, their complex structure and high maintenance costs make it difficult to meet the actual needs for efficient, convenient and comprehensive purification.

[0004] Therefore, in view of the problems of existing filters, such as limited functionality, cumbersome cleaning, and complex structure, which make it difficult to remove ferromagnetic impurities and non-magnetic particles simultaneously and efficiently, and the inconvenience of maintenance, affecting the efficiency and purification effect, there is an urgent need to design a new type of magnetic basket filter. Utility Model Content

[0005] To overcome the problems of existing filters, such as limited functionality, cumbersome cleaning, complex structure, difficulty in simultaneously and efficiently removing ferromagnetic impurities and non-magnetic particles, and inconvenient maintenance, which affect usage efficiency and purification effect.

[0006] The technical solution of this utility model is as follows: a magnetic basket filter, comprising a tube body and a filter cylinder disposed inside the tube body, a positioning pin fixedly installed on the bottom side inside the filter cylinder, a magnetic suction rod disposed above the positioning pin, a sleeve installed at the bottom of the magnetic suction rod, a threaded cap rotatably connected to the magnetic suction rod, an arc plate disposed on the top of the filter cylinder, a threaded sleeve installed on the top of the arc plate, a fixing plate installed in the middle of the filter cylinder, mounting holes provided on both the arc plate and the fixing plate, a filter basket disposed on the rear side inside the filter cylinder, a connecting ring installed on the top of the filter cylinder, and a differential pressure gauge disposed on the top of the tube body. The connecting ring is inclined, the magnetic suction rod matches the mounting hole, the threaded cap is threadedly connected to the threaded sleeve, the sleeve is movably connected to the positioning pin, the filter cylinder is movably connected to the tube body, and the arc plate is connected to the connecting ring.

[0007] Preferably, by setting up a magnetic suction rod and a filter basket, after sewage enters the filter cartridge, metal particles are attracted by the magnetic suction rod, while fixed particles are intercepted by the filter basket. When the differential pressure gauge shows that the internal pressure difference of the tube is too high, the filter cartridge is pulled out of the tube by pulling the arc plate, the threaded cover is rotated to separate the threaded cover from the threaded sleeve, the magnetic suction rod is pulled upward and removed from the mounting hole, and then the metal particles around the magnetic suction rod are scraped off. The filter basket is then cleaned. The filter basket and the magnetic component are integrated into the same housing structure, so that solid particles are intercepted and ferromagnetic impurities are adsorbed simultaneously when the fluid enters, which improves the filtration efficiency and purification effect. At the same time, a differential pressure monitoring device is equipped to promptly remind the user to clean and maintain when the pressure difference is too high. The user only needs to open the top cover of the housing to remove the filter basket and rinse the magnetic component. The operation is simple and quick, without complicated disassembly and assembly, effectively reducing the maintenance difficulty and downtime.

[0008] Preferably, connecting pipes are provided at both ends of the pipe body, and a flange ring is connected to the end of the connecting pipe away from the pipe body.

[0009] Preferably, the flange ring is connected to the external pipeline, and a drain port is provided on the lower front end of the pipe body.

[0010] Preferably, the sewage outlet is connected to an external pipe, and a top ring is connected to the top of the pipe.

[0011] Preferably, the top ring has four threaded rods connected by equally spaced threads inside, and a nut is threaded to the upper side of the outer end of each threaded rod.

[0012] Preferably, the nut is movably connected to the cover plate, the cover plate is movably connected to the top ring, and a differential pressure gauge is provided on the top of the top ring.

[0013] Preferably, the nut is rotatably connected to the threaded rod, so that the nut presses against the cover plate.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up magnetic adsorption and basket filtration functions, it can simultaneously and efficiently remove ferromagnetic impurities and non-magnetic solid particles from fluids, achieving dual purification and improving filtration accuracy. During operation, the filter can simultaneously intercept non-magnetic solid particles (such as sand and gravel) and adsorb ferromagnetic impurities (such as iron filings and rust) from the fluid, effectively making up for the limitations of a single filtration method. This dual purification mechanism not only significantly improves filtration accuracy and efficiency, but also reduces the risk of wear and blockage of subsequent equipment caused by impurities, and extends the service life of the system.

[0016] 2. Its compact structure facilitates disassembly and cleaning, avoiding frequent downtime for maintenance and significantly improving operational efficiency and ease of use. At the same time, compared with traditional complex combined structures, this device optimizes the construction while ensuring functionality, reducing maintenance costs and improving overall applicability and industrial operational reliability. It is suitable for industries such as petroleum and chemical industries that have high requirements for fluid cleanliness. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5This utility model provides an embodiment of a magnetic basket filter, comprising a tube body 1 and a filter cylinder 21 disposed inside the tube body 1, a positioning pin 22 fixedly installed on the bottom side inside the filter cylinder 21, a magnetic suction rod 23 disposed above the positioning pin 22, a sleeve 24 installed at the bottom of the magnetic suction rod 23, a threaded cap 25 rotatably connected to the magnetic suction rod 23, an arc plate 26 disposed on the top of the filter cylinder 21, a threaded sleeve 27 installed on the top of the arc plate 26, and a sleeve 27 installed in the middle of the filter cylinder 21. Fixed plate 28, mounting holes 29 both opened on arc plate 26 and fixed plate 28, filter basket 210 set inside the rear side of filter cylinder 21, connecting ring 211 installed on the top of filter cylinder 21, differential pressure gauge 212 set on the top of tube body 1, connecting ring 211 is inclined, magnetic rod 23 matches the mounting hole 29, threaded cap 25 is threadedly connected to threaded sleeve 27, sleeve 24 is movably connected to positioning pin 22, filter cylinder 21 is movably connected to tube body 1, arc plate 26 and connecting ring Connected to 211, by setting up a magnetic suction rod 23 and a filter basket 210, after sewage enters the filter cylinder 21, metal particles are attracted by the magnetic suction rod 23, while fixed particles are intercepted by the filter basket 210. When the differential pressure gauge 212 shows that the internal pressure difference of the pipe body 1 is too high, the filter cylinder 21 is pulled out of the pipe body 1 by pulling the arc plate 26, the threaded cover 25 is rotated to separate the threaded cover 25 from the threaded sleeve 27, the magnetic suction rod 23 is pulled upward and removed from the mounting hole 29, thereby attracting the magnetic... The metal particles around the suction rod 23 are scraped off, and the filter basket 210 is then cleaned. The filter basket and magnetic components are integrated into the same housing structure, so that solid particles are intercepted and ferromagnetic impurities are adsorbed simultaneously when fluid enters, which improves filtration efficiency and purification effect. At the same time, a differential pressure monitoring device is equipped, which can remind you to clean and maintain the machine in time when the differential pressure is too high. Users only need to open the top cover of the housing, take out the filter basket and rinse the magnetic components. The operation is simple and quick, without complicated disassembly and assembly, which effectively reduces maintenance difficulty and downtime.

[0025] Please see Figures 1-2 In this embodiment, connecting pipes 31 are provided at both ends of the pipe body 1. A flange ring 32 is connected to the end of the connecting pipe 31 away from the pipe body 1. The flange ring 32 facilitates the connection of the device to the external pipeline. The flange ring 32 is connected to the external pipeline. A sewage outlet 33 is provided on the lower side of the front end of the pipe body 1. The sewage outlet 33 is used to discharge sewage. The sewage outlet 33 is connected to the external pipeline. A top ring 34 is connected to the top of the pipe body 1.

[0026] Please see Figures 2-5In this embodiment, the top ring 34 has four threaded rods 35 connected by equally spaced threads inside. Nuts 36 are threaded to the upper outer ends of the threaded rods 35 and are movably connected to the cover plate 37. The cover plate 37 is movably connected to the top ring 34. A differential pressure gauge 212 is provided on the top of the top ring 34. The cover plate 37 is fitted to the top ring 34 by the threaded rods 35 through the threaded connection of the nut 36, so that the cover plate 37 covers the pipe body 1 to prevent sewage leakage. The nut 36 is rotatably connected to the threaded rods 35, so that the nut 36 presses the cover plate 37. The nut 36 restricts the position of the cover plate 37, so that the cover plate 37 fits tightly with the top ring 34. After the restriction of the cover plate 37 by the nut 36 is released, the cover plate 37 can be taken out, so that the filter cartridge 21 can be taken out for cleaning.

[0027] During operation, first connect the external pipe to the flange ring 32. After connection, connect the drain port 33 to the external pipe. Then, place the filter cylinder 21 inside the pipe body 1 and cover it with the cover plate 37. Fix the cover plate 37 by connecting the nut 36 and the threaded rod 35 to restrict its position and ensure a sealing effect. After the sewage flows into the filter cylinder 21 through the connecting pipe 31, the magnetic suction rod 23 set inside the cylinder can adsorb metal particles in the sewage, while the filter basket 210 is used to intercept other solid impurities. The filtered liquid is discharged through the connecting pipe 31 at the other end, and the drain port 33 at the bottom can be used to flush out the deposited dust. When the differential pressure gauge 212 shows that the pressure difference inside the pipe body 1 is too high, it indicates that the device needs to be adjusted. For cleaning and maintenance, the nut 36 can be rotated to disengage it from the threaded rod 35. Then, the cover plate 37 can be removed from the top ring 34, the tube body 1 can be opened, and the filter cylinder 21 can be pulled out from the inside by pulling the arc plate 26. Then, the threaded cover 25 can be rotated to separate it from the threaded sleeve 27. Then, the magnetic rod 23 can be pulled upward to remove it from the mounting hole 29. The metal particles attached to the magnetic rod 23 can be removed. At the same time, the filter basket 210 can be cleaned. When reinstalling, the magnetic rod 23 can drive the sleeve 24 to pass through the mounting holes 29 on the arc plate 26 and the fixing plate 28 in sequence, and the sleeve 24 can be accurately engaged with the positioning pin 22. This completes the reinstallation of the magnetic rod 23 and ensures that the device returns to normal operation.

[0028] Through the above steps, by integrating magnetic adsorption and basket filtration functions, the filter can simultaneously intercept non-magnetic solid particles (such as sand and impurities) and adsorb ferromagnetic impurities (such as iron filings and rust) in the fluid during operation. This achieves synergistic purification of different types of impurities, effectively overcoming the limitations of traditional filtration methods. This dual filtration structure not only significantly improves impurity removal efficiency and filtration accuracy, but also effectively reduces the risk of wear and blockage to downstream equipment caused by impurities, further extending the stable operating cycle and service life of the entire system. This solves the problems of existing filters, such as single function, cumbersome cleaning, complex structure, difficulty in simultaneously and efficiently removing ferromagnetic impurities and non-magnetic particles, and inconvenient maintenance, which affect usage efficiency and purification effect.
