Description

Technical Field

[0001] The present invention relates to the technical field of removing magnetic substances from fluid materials, and particularly to a mechanism for automatically removing magnetic substances from fluid materials. Background Art

[0002] In the industrial production process, magnetic removal of materials is a key link to ensure product quality, stable operation of production equipment, and compliance with industry safety standards. Especially in industries with extremely strict requirements for product quality, magnetic substances mixed in fluid materials will not only seriously affect the purity, performance, and appearance of products, but may also cause irreparable damage to subsequent production processes and final product quality. Currently, the industry generally uses 8 material filter pipes arranged in a row for magnetic adsorption filtration, and a magnetic bar with a diameter of φ45 is used to adsorb magnetic substances in the materials. This traditional magnetic removal method has exposed many problems that need to be solved urgently in practical applications;

[0003] In terms of the magnetic removal effect, in the initial stage, the magnetic bar can effectively adsorb magnetic substances in the materials. However, as the use time prolongs, the magnetic substances adsorbed on the magnetic bar gradually increase. These adsorbed magnetic substances will form a "barrier" on the surface of the magnetic bar, hindering the effective contact between subsequent magnetic substances and the magnetic bar, resulting in a significant decline in the magnetic removal effect and being unable to meet the production requirements for high material purity. Since the magnetic bar needs to be manually cleaned regularly after adsorbing magnetic substances, and the magnetic removal device must be stopped during the cleaning process, this not only consumes a large amount of manpower, but also makes the magnetic removal work unable to be carried out continuously, seriously affecting the magnetic removal efficiency, and further disrupting the rhythm of the entire production process, increasing production costs and production cycles;

[0004] In summary, the deficiencies in the cleaning efficiency of the existing material magnetic removal methods seriously restrict the efficiency and quality of industrial production. Therefore, it is of great practical significance to develop a magnetic removal device that can effectively improve the magnetic removal effect, realize automatic cleaning, facilitate the disassembly and assembly of the magnetic bar, and have an automated process control.

The end of the welded chuck needs to be fully welded without gaps.

[0013] As a further scheme of the present invention: a connecting pipe is installed on the circumferential outer wall of the material filtering pipe, and the connecting pipes between two adjacent material filtering pipes are connected through a flexible pipe. The multiple connecting pipes are connected through an airbag, and the airbag is connected to a gas supply mechanism through the connecting pipe.

[0014] As a further scheme of the present invention: the gas supply mechanism includes an air cylinder, a spring and a piston plate. The air cylinder is fixed to the end of the connecting pipe, a slide rod is movably connected to the inner wall of a through hole opened at one end of the air cylinder, the piston plate is fixed to one end of the slide rod, the spring is sleeved on the outer wall of the slide rod, and the two ends of the spring are respectively fixed between the air cylinder and the piston plate.

[0017] Compared with the prior art, the present invention provides a mechanism for automatically removing magnetic substances in fluid materials, and has the following beneficial effects:

[0018] 1. By setting a lifting component to control the up and down movement of the magnetic rod in the material filtering pipe, the magnetic rod adsorbs magnetic substances when the fluid flows through, realizing efficient removal. And a non-magnetic area is left at the bottom of the magnetic rod as a guide to ensure that the magnetic rod can be smoothly inserted into the magnetic sleeve, improving the reliability and stability of magnetic substance removal.

[0019] 2. The magnetic sleeve is used to suck and clean the magnetic substances adsorbed on the magnetic rod.

At the same time, the stability of the lifting of the magnetic rod is ensured.

[0020] 3.

The inflation and deflation of the airbag are controlled by a gas supply mechanism, avoiding the overflow of magnetic substances from the gap between the magnetic rod and the magnetic sleeve. At the same time, during the lifting process of the magnetic rod, the airbag can clean other substances attached to the magnetic rod by scraping, further improving the effect of magnetic substance removal and the cleanliness of the equipment.

[0034] Embodiment 1:

[0035] A mechanism for automatically removing magnetic substances in fluid materials. In order to improve the cleaning effect on magnetic substances, as Figures 1 to 4 shown, it includes a support steel frame 4. A plurality of material filter pipes 2 are fixed on the support steel frame 4 through pipe clamps 17, and a U-shaped pipe 6 is connected between two adjacent material filter pipes 2 through a stainless steel quick-installation clamp. A lifting assembly is installed on the support steel frame 4, a floating joint 15 is installed on the lifting assembly, and a magnetic rod 14 is installed at the bottom of the floating joint 15. A magnetic sleeve 8 is installed at the top of the material filter pipe 2, and the magnetic sleeve 8 and the magnetic rod 14 are used in cooperation;

[0036] The entire mechanism is connected in an S shape by 24 material filter pipes 2 and 12 U-shaped pipes 6. By setting a lifting assembly, the magnetic rod 14 can be controlled to move up or down along the inside of the material filter pipe 2. When magnetic substances need to be removed, the lifting assembly is used to drive the magnetic rod 14 to move down so that the magnetic rod 14 extends into the material filter pipe 2. When the fluid flows through the material filter pipe 2, the magnetic rod 14 adsorbs the magnetic substances in the fluid to achieve the removal of the magnetic substances in the fluid. In this embodiment, a non-magnetic area of 50 - 80 mm is left at the bottom of the magnetic rod 14, so that this part can be used as a guide to enable the magnetic rod 14 to be smoothly inserted back into the magnetic sleeve 8;

[0037] When it is necessary to clean the magnetic substances adsorbed on the magnetic rod 14, the lifting assembly is used to drive the magnetic rod 14 to move up. During the upward movement of the magnetic rod 14, the magnetic sleeve 8 sucks the magnetic substances on the magnetic rod 14, and the magnetic sleeve 8 is used to clean the magnetic substances adsorbed on the magnetic rod 14. The outer diameter of the magnetic rod 14 should be 0.3 - 0.5 mm smaller than the inner diameter of the magnetic sleeve 8, and the outer surface of the magnetic rod 14 is ground to a mirror surface to ensure that the magnetic rod 14 can be smoothly inserted and pulled out of the magnetic sleeve 8 and the wear caused by the friction between the two is small, so as to ensure the stability of the magnetic rod 14 during rising and falling and improve the service life of the magnetic sleeve 8 and the magnetic rod 14.

[0038] The lifting assembly includes a lifting cylinder 3 and a lifting steel frame 1. The lifting cylinder 3 is fixed to the inner wall of the top of the support steel frame 4 through bolts, the lifting steel frame 1 is fixed to the output end of the lifting cylinder 3 through pins, and a linear bearing 16 is installed on the inner wall of the top of the support steel frame 4;

[0039] The height of the lifting steel frame 1 can be adjusted by using the lifting cylinder 3. Furthermore, the height of the magnetic rod 14 can be adjusted by using the lifting steel frame 1. To eliminate the errors caused by insufficient parallelism or non-concentricity between the magnetic rod 14 and the magnetic sleeve 8, a floating joint 15 is used to connect the magnetic rod 14 and the lifting steel frame 1. Lifting cylinders 3 need to be installed on both sides of the lifting steel frame 1 to achieve the lifting function. Guide rods are installed on both sides respectively to prevent the lifting cylinders 3 from shaking or shifting during operation, thereby ensuring the positioning accuracy and stability of the lifting cylinders 3 and enabling the magnetic rod 14 to achieve the lifting function more smoothly. Positioning blocks are installed below the guide rods for positioning to ensure the rising height. The support steel frame 4 is fixed to the ground by four square tube columns, and two steel plates are fixed above to connect the lifting cylinders 3. Two linear bearings 16 are installed on both sides of each steel plate for guiding the guide rods of the lifting structure connected to the magnetic rod 14.

[0040] A pneumatic feed valve 9 is installed at the inlet of the material filter pipe 2, and a pneumatic discharge valve 11 is installed at the outlet of the material filter pipe 2;

[0041] By setting the pneumatic feed valve 9, the fluid to be processed can be input into the interior of the material filter pipe 2. By setting the pneumatic discharge valve 11, the fluid after removing the magnetic substances can be discharged.

[0042] A discharge pipe 7 is fixed to the bottom of the U-shaped pipe 6 through a pneumatic bottom valve 5, and the outlet of the discharge pipe 7 is connected to a pneumatic discharge valve 12 and a pneumatic sewage discharge valve 13 respectively by a tee. A nipple 10 is welded at the upper end of the material filter pipe 2 and the lower end of the U-shaped pipe 6;

[0043] By setting the nipple 10, a flushing and purging pipe can be installed. The nipple 10 at the upper end of the material flushing and purging pipe needs to be welded at an angle of 45° upward to flush the dead angle at the upper end of the magnetic sleeve 8. The nipple 10 at the lower end of the connection discharge pipe 7 is welded vertically upward. To improve the flushing effect, a sector-shaped spray head is installed inside the U-shaped pipe 6 at this nipple 10 to increase the flushing area of the magnetic sleeve 8 and the flushing water pressure. Check valves need to be connected when the two welded nipples 10 are led out to ensure that the material will not flow out from these two ports. For the convenience of manufacturing and disassembly, the discharge pipe is split into three sections for manufacturing, and each section is butt-connected to 4 U-shaped pipes 6. A quick-installation steel wire hose is used to connect between every two sections. The outlet of the discharge pipe is connected to a tee and is respectively installed with a pneumatic discharge valve 12 and a pneumatic sewage discharge valve 13 to control material recovery and flushing and sewage discharge respectively. The sleeve part of the magnetic sleeve 8 is made of a stainless steel thin-walled pipe with a thickness of 0.2 mm to ensure that the magnetic force on the outer surface of the magnetic sleeve 8 can meet the magnetic force requirements after the magnetic rod 14 is inserted into the magnetic sleeve 8. Since the thin-walled pipe of the magnetic sleeve 8 needs to be inserted and pulled out of the magnetic rod 14 and needs to be cleaned after external magnetic substances adhere, it is necessary to ensure that the internal and external friction of the thin-walled pipe is small, so the internal and external surfaces of the thin-walled pipe need to be mirror-finished. One end of the thin-walled pipe is sealed, and a chuck is welded at the other end for connection with the material filter pipe 2. The end where the chuck is welded needs to be fully welded without gaps to prevent magnetic substances from entering and being unable to be cleaned.

[0044] Working principle: Open the pneumatic feed valve 9 and the pneumatic discharge valve 11, and at the same time close the pneumatic bottom valve 5, the pneumatic discharge valve 12 and the pneumatic sewage discharge valve 13 to ensure that the fluid can smoothly enter and discharge from the material filter tube 2. The lifting cylinder 3 drives the lifting steel frame 1 to descend, so that the magnetic rod 14 smoothly extends into the magnetic sleeve 8 inside the material filter tube 2 through the floating joint 15. The fluid enters the material filter tube 2 through the pneumatic feed valve 9. When flowing through the magnetic rod 14, the magnetic rod 14 adsorbs the magnetic substances in the fluid to achieve the removal of magnetic substances. The fluid after removing the magnetic substances is discharged through the pneumatic discharge valve 11 and enters the next process. Close the pneumatic feed valve 9 and the pneumatic discharge valve 11 to stop the inflow and outflow of the fluid. Open the pneumatic bottom valve 5 to discharge the residual fluid in the material filter tube 2, and recycle it through the pneumatic discharge valve 12. The lifting cylinder 3 drives the lifting steel frame 1 to rise, so that the magnetic rod 14 is pulled out of the magnetic sleeve 8. The magnetic sleeve 8 absorbs and retains the magnetic substances adsorbed on the magnetic rod 14. The flushing and purging pipe installed through the screw head 10 on the material filter tube 2 and the U-shaped pipe 6 is used to introduce pure water to flush the magnetic sleeve 8 and the material filter tube 2. The flushing water is discharged through the pneumatic sewage discharge valve 13. After flushing, compressed air can be introduced through the cleaning and purging port on the material filter tube 2 and the U-shaped pipe 6 to quickly discharge the residual cleaning water to ensure the dryness and cleanliness of the magnetic sleeve 8 and the material filter tube 2. The lifting cylinder 3 drives the lifting steel frame 1 to descend, so that the magnetic rod 14 is reinserted into the magnetic sleeve 8 to prepare for the next magnetic adsorption work process.

[0045] Example 2:

[0046] An apparatus for automatically removing magnetic substances from fluid materials, as Figures 5 to 7 shown. In order to improve the cleaning effect on other substances, the following supplements are made on the basis of Example 1: A connecting pipe 26 is installed on the circumferential outer wall of the material filter tube 2, and the connecting pipes 26 between adjacent two material filter tubes 2 are connected through a flexible tube 22. The plurality of connecting pipes 26 are connected through an airbag 30, and the airbag 30 is connected with a gas supply mechanism through the connecting pipe 26;

[0047] An airbag 30 is installed at the connection between the material filtering pipe 2 and the magnetic sleeve 8. When the air supply mechanism inflates the inside of the airbag 30 through the connecting pipe 26, the airbag 30 expands after inflation and fits tightly against the outer wall of the magnetic rod 14. Thus, it can be ensured that when the fluid flows through the material filtering pipe 2, magnetic substances are prevented from overflowing from the gap between the magnetic rod 14 and the magnetic sleeve 8. When it is necessary to clean the magnetic substances adsorbed on the magnetic rod 14, the air supply mechanism first exhausts air, causing the airbag 30 to collapse after exhausting. At this time, when the magnetic rod 14 moves upward along the magnetic sleeve 8 driven by the lifting assembly, the magnetic sleeve 8 adsorbs the magnetic substances on the magnetic rod 14. When the magnetic rod 14 moves downward and resets driven by the lifting assembly, after the airbag 30 inflates again and expands, when the magnetic rod 14 slides along the airbag 30 that tightly wraps it, when the magnetic rod 14 moves upward again, other substances attached to the magnetic rod 14 are cleaned by scraping using the airbag 30.

[0048] The air supply mechanism includes an air cylinder 25, a spring 28, and a piston plate 29. The air cylinder 25 is fixed to the end of the connecting pipe 26, and the sliding rod 24 is slidably connected to the inner wall of the through hole opened at one end of the air cylinder 25. The piston plate 29 is fixed to one end of the sliding rod 24 by screws. The spring 28 is sleeved on the outer wall of the sliding rod 24, and both ends of the spring 28 are respectively fixed between the air cylinder 25 and the piston plate 29.

[0049] When the sliding rod 24 drives the piston plate 29 to perform a forward movement along the inside of the air cylinder 25, the piston plate 29 squeezes the gas inside the air cylinder 25. After being squeezed, the gas enters the airbags 30 in the plurality of material filtering pipes 2 through the flexible pipe 22, and the airbags 30 inflate and expand. When the sliding rod 24 performs a return movement along the inside of the air cylinder 25, part of the gas flows back into the air cylinder 25, causing the air cylinder 25 to collapse.

[0050] A protective shell 19 is fixed to one end of the air cylinder 25 through a bracket mechanism. An electromagnet 27 is fixed to the inner wall of one side of the protective shell 19 by screws, and a permanent magnet 23 that cooperates with the electromagnet 27 is fixed to one end of the sliding rod 24 by screws.

[0051] In the initial state, when the electromagnet 27 is in the power-off state, the airbag 30 is in a collapsed state. When the electromagnet 27 is powered on, it repels the permanent magnet 23. The repulsive force overcomes the elastic force of the spring 28, causing the piston plate 29 to perform a return movement along the inside of the air cylinder 25. In this embodiment, the number of air supply mechanisms is not specifically limited, so as to ensure that it meets the inflation requirements.

[0052] The bracket mechanism includes a pipe clamp one 18, a piston plate 29, and a pipe clamp three 21. The pipe clamp three 21 is fixed to the circumferential outer wall of the material filtering pipe 2, and the pipe clamp one 18 is fixed to the circumferential outer wall of the air cylinder 25. The pipe clamp one 18 and the pipe clamp three 21 are welded and fixed through a connecting rod 20.

[0053] The support stability for the air supply mechanism can be improved by setting up a support mechanism.

[0054] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
