Description

Technical Field

[0001] The invention relates to a magnetic filter, in particular to a magnetic filter capable of continuously operating online and automatically removing chips. Background Art

[0002] In industrial production, various fluids such as liquids, slurries or gases are often mixed with iron filings, iron powder and other ferromagnetic impurities. These impurities may enter the compressor, pump and other equipment, causing equipment damage or wear; these impurities enter the hydraulic system and pneumatic pipelines, causing hydraulic components and pneumatic components to get stuck or friction pairs to wear, so it is necessary to separate the fine iron filings contained in the liquid medium to meet environmental protection requirements.

[0003] The magnetic filter is a filtering device that uses permanent magnetic attraction to remove tiny ferromagnetic impurities in the fluid. When the fluid passes through the magnetic filter, the magnetic force adsorbs the tiny magnetic impurities in the fluid, thereby achieving efficient separation and purification of the fluid.

[0004] For example, heavy oil, iron sludge and other debris often remain on the coils of plates and strips that have been rolled by the rolling mill. These debris must be cleaned with alkali before the next process, and the cleaned oil sludge impurities fall into the bottom of the tank; another example: iron pollutants in boiler feed water will cause complex iron scale to form inside the furnace tube, causing the quality of water vapor to deteriorate, and will also have a bad impact on the efficiency and reliability of the unit, and even threaten the safe operation of the unit. The magnetic filter is a special equipment used to separate fine iron filings in liquid media, and is widely used in steel, smelting, casting, boilers and other fields.

[0005] At present, the iron removal equipment at home and abroad mainly includes electromagnetic filters, permanent magnetic filters, etc. The application effect of permanent magnetic filters is good, but its structural design is simple. It needs to be disassembled and removed from time to time according to the degree of scrap iron adsorption, which is inefficient and affects the continuity of filtration, and further affects the continuity of the production system. The current response measure is to spare a set of redundant magnetic filtration devices. One set is used and one set is spare. When cleaning the sediment of a magnetic filtration system, the redundant spare set is replaced. Although this solution solves the problems of continuous filtration and continuous production, it greatly increases the operating cost and floor space. In addition, fluid pipelines and filtration and environmental protection devices are generally not indoors, so there are few mechanical equipment such as cranes available. Outdoors or even in the wild, when manually cleaning, when opening the heavy cover (tens of millimeters thick steel plate, weighing hundreds of kilograms), in order to enhance the magnetic force's adsorption capacity and filtration efficiency for ferromagnetic impurities, strong magnets are generally used, which greatly increases the difficulty of manually removing ferromagnetic impurities from the magnet, so the physical labor intensity of the cleaning workers is very high, and there are disadvantages such as potential accidents. Summary of the invention

[0006] In view of the defects of existing permanent magnetic filters, the production line needs to be shut down during operation (the filtered pipeline stops conveying fluid), and it cannot operate continuously. Workers have to disassemble heavy iron covers and other parts, and the cleaning time may take several hours. A magnetic filter that can continuously filter and automatically clean iron filings adsorbed by permanent magnets is proposed, thereby avoiding system interruptions and tedious manual disassembly and can operate continuously online with automatic chip removal.

[0007] In order to solve the above technical problems, the magnetic filter capable of continuously operating online automatic chip removal of the present invention comprises a flow channel capable of allowing a fluid containing iron chips to flow through, a permanent magnetic adsorption component arranged in the flow channel, and a pusher mounted on each of the permanent magnetic adsorption components and capable of being driven by a propeller to reciprocate up and down. The permanent magnetic adsorption component can adsorb waste chips contained in the fluid flowing in the flow channel. A cleaning area for isolating the fluid in the flow channel is also provided in the flow channel, which is formed by the cooperation of the permanent magnetic adsorption component and the pusher. The pusher can push the iron chips adsorbed on the permanent magnetic adsorption component and accumulate them in the cleaning area through the drive of the propeller, and then send them out of the flow channel by the external fluid.

[0008] The pusher has an upper trough body that can cooperate with the top of the flow channel to form the material cleaning area and a lower trough body that can cooperate with the bottom of the flow channel to form the material cleaning area. The flow channel is also respectively provided with an upper connecting port corresponding to the upper material cleaning area and a lower connecting port corresponding to the lower material cleaning area. The external fluid connected through the upper connecting port or the lower connecting port can send the iron filings accumulated in the material cleaning area out of the shell.

[0009] The top of the flow channel has an upper partition installed horizontally and located in the upper cleaning area, the bottom of the flow channel has a lower partition installed horizontally and located in the lower cleaning area, and the permanent magnetic adsorption component is arranged horizontally between the upper partition and the lower partition.

[0010] The permanent magnetic adsorption component comprises a sleeve made of non-ferromagnetic material fixedly installed between an upper partition plate and a lower partition plate, and a permanent magnetic adsorption column arranged in the sleeve.

[0011] The length of the permanent magnetic column is less than the length of the sleeve and can move up and down in the sleeve. The upper partition is arranged with an upper channel for communicating with the inner cavity of each sleeve, and the lower partition is arranged with a lower channel also for communicating with the inner cavity of each sleeve. The top of the flow channel is provided with an upper notch for introducing a power medium into the upper channel, and the bottom of the flow channel is provided with a lower notch for introducing a power medium into the downward channel.

[0012] The upper channel and the lower channel are both stepped holes, and the large diameter section of each stepped hole is equivalent to the diameter of the permanent magnetic suction column, so as to expand the moving range of the permanent magnetic suction column.

[0013] The pusher is an H-shaped member composed of two side plates and a horizontal plate arranged horizontally in the middle of the two side plates. The horizontal plate is provided with through holes that cooperate with each of the permanent magnetic adsorption components. The H-shaped member is divided into two upper and lower cavities by the horizontal plate for forming the material cleaning area.

[0014] The height of the upper trough body is equal to that of the upper partition, the height of the lower trough body is equal to that of the lower partition, the width of the upper trough body is greater than that of the upper partition, and the width of the lower trough body is greater than that of the lower partition.

[0015] The bottom surface of the upper partition is processed with an arrangement upper groove, and the top surface of the lower partition is processed with an arrangement lower groove. When the upper groove body contacts the upper partition or the lower groove body contacts the lower partition, a flushing channel can be formed; The propeller is a screw transmission device, a hydraulic device, a pneumatic device or an electric propulsion device; The propeller is provided with a sensor for detecting the degree of iron filings accumulation; The flow channel comprises a filter housing and two adapter flanges arranged on the housing and on the left and right sides, and the adapter flanges are connected to the filter pipeline.

[0016] The advantages of the present invention are: (1) Through the permanent magnetic adsorption component, the pusher and the cleaning area formed by the permanent magnetic adsorption component and the pusher arranged in the flow channel, the iron filings adsorbed on the permanent magnetic adsorption component can be accumulated in the cleaning area by the pusher without stopping the machine and sent out of the flow channel by the external fluid, thereby achieving the purpose of continuous online filtration and automatic cleaning of the iron filings adsorbed by the permanent magnet. In particular, during the entire cleaning process, not only can the system be avoided from being interrupted, but also manual participation (disassembling the filter) is not required, which greatly improves the work efficiency and effectively reduces the labor intensity of the operators.

[0017] (2) The pusher is directly designed to move up and down along the permanent magnetic adsorption component to scrape the material. On the other hand, the upper and lower trough bodies are used to form two upper and lower cleaning areas, which work alternately and can send the iron filings adsorbed in the two cleaning areas out of the shell respectively, further improving the work efficiency.

[0018] (3) A permanent magnetic adsorption component is formed by a sleeve and a permanent magnetic column, and the length of the permanent magnetic column is designed to be smaller than the length of the sleeve. At the same time, the upper and lower partitions are cleverly used to design the upper and lower channels that match them. Therefore, in addition to using the upper and lower partitions as the main supporting components of the permanent magnetic adsorption component, the channel structure set on the upper and lower partitions is cleverly used to allow the permanent magnetic column to reciprocate up and down in the sleeve. Therefore, during the cleaning process, the permanent magnetic column is driven away from the corresponding cleaning area, effectively avoiding the problem of cleaning difficulties caused by magnetic adsorption of iron filings.

[0019] (4) By designing the upper and lower channels as stepped holes and the large diameter section of each stepped hole is equivalent to the diameter of the permanent magnetic column, the moving range of the permanent magnetic column is expanded. Its special structural design greatly increases the stroke of the permanent magnetic column, avoids the influence of the magnetic force of the permanent magnetic column on the cleaning area to the greatest extent, and further improves the cleaning effect.

[0020] (5) The height of the upper and lower trough bodies is designed to be equal to the height of the upper and lower partitions. At the same time, the width of the upper and lower trough bodies is greater than the width of the upper and lower partitions. There is space between the partitions and the side walls of the trough bodies to accommodate iron filings, so that the iron filings fall into the space, which is conducive to centralized flushing and cleaning, further improving the cleaning effect.

[0021] (6) Upper and lower grooves are processed on the upper and lower partitions respectively, so that after the upper trough body contacts the end faces of the upper and lower partitions, the grooves can be used to form a flushing channel, thereby avoiding the accumulation of iron filings on the end faces of the upper and lower partitions, and further improving the cleaning effect.

DETAILED DESCRIPTION

[0023] The magnetic filter capable of continuous operation and automatic online chip removal of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Example

[0024] As shown in the figure, the magnetic filter capable of continuous operation and automatic chip removal in the present embodiment comprises a flow channel 1 through which a liquid containing iron chips can flow, a plurality of permanent magnetic adsorption components 2 arranged in a row in the flow channel, and a pusher 4 mounted on each permanent magnetic adsorption component and capable of being driven by a propeller 3 to move up and down reciprocatingly. Figure 2 It can be seen that in this embodiment, the flow channel includes a filter housing 21 and two adapter flanges 22 connected to the left and right sides of the filter housing 21. The adapter flanges are used to connect the filter pipe. The liquid containing iron filings can flow from left to right in the filter housing 21 (that is, flow along the longitudinal direction of the filter housing). The filter housing has a transversely arranged upper partition and a lower partition. The upper partition is installed on the top of the filter housing, and the lower partition is installed on the bottom of the filter housing. The permanent magnetic adsorption component 2 includes a plurality of sleeves 12 and permanent magnetic suction columns 13 arranged in each sleeve. The permanent magnetic suction column is formed by superimposing permanent magnets, and is either circular or square. The shape is determined according to the actual production environment. The number of permanent magnetic adsorption components 2 is set according to the amount to be filtered. The sleeve is made of non-ferromagnetic material. The upper partition and the lower partition correspond to each other in the vertical direction. Therefore, the sleeve 12 can be fixedly installed between the upper partition and the lower partition, so that the upper partition and the lower partition serve as support members of the permanent magnetic adsorption component 2. After the installation of this specific structure, each permanent magnetic adsorption component 2 is neatly arranged horizontally in the filter housing, that is, the arrangement direction of the permanent magnetic adsorption component 2 is perpendicular to the flow direction of the liquid, and the waste contained in the liquid flowing through the filter housing can be adsorbed by the permanent magnetic adsorption component 2; The pusher 4 has an upper tank body 6 and a lower tank body 7, wherein the height of the upper tank body 6 is equivalent to the height of the upper partition 10, the height of the lower tank body 7 is equivalent to the height of the lower partition 11, the width of the upper tank body 6 is greater than the width of the upper partition 10, and the width of the lower tank body 7 is greater than the width of the lower partition 11, so as to form a flow cavity for the external fluid to pass through. When the pusher 4 moves to the top of the filter housing along the permanent magnetic adsorption component, the upper partition is sealed in the upper tank body to form an upper isolation flushing cavity (i.e., the upper cleaning area) that is completely isolated from the filter housing. When the filter housing is moved to the bottom of the filter housing, the lower partition is sealed in the lower tank body to form a lower isolation flushing cavity (i.e., the lower cleaning area) which is completely isolated from the filter housing, thereby forming upper and lower cleaning areas. The front side wall and the right side wall of the filter housing are also provided with an upper connecting port 8 corresponding to the upper isolation flushing cavity and a lower connecting port 9 corresponding to the lower isolation flushing cavity, respectively. The iron filings adsorbed on the permanent magnetic adsorption component can be pushed by the pusher and accumulated in the cleaning area, and then the external fluid connected through the upper connecting port 8 or the lower connecting port 9 is sent out of the filter housing.

[0025] Furthermore, the pusher 4 is an H-shaped member composed of two side plates 18 and a horizontal plate 19 laterally arranged in the middle of the two side plates. The H-shaped member is divided by the horizontal plate into an upper clearing area located at the top of the filter housing and a lower clearing area located at the bottom of the filter housing. The horizontal plate 19 is provided with through holes that cooperate with each permanent magnetic adsorption component, and the permanent magnetic adsorption component is mounted on the H-shaped member through the through holes.

[0026] Furthermore, the bottom surface of the upper partition 10 is processed with a lower groove, and a plurality of lower bosses serving as raised surfaces are formed after the upper groove is processed. The top surface of the lower partition 11 is processed with an upper groove, and a plurality of upper bosses 29 serving as raised surfaces are formed after the lower groove is processed. As a result, a flushing channel can be formed when the upper trough body 6 contacts the bottom surface of the upper partition 10 or the lower trough body 7 contacts the top surface of the lower partition 11 (the top surface is a raised surface formed after the upper groove is processed). This structural design can effectively prevent iron filings from accumulating on the contact surface between the upper trough body 6 and the upper partition 10 or on the contact surface between the lower trough body 7 and the lower partition 11. Example

[0027] Since the present invention adopts a permanent magnetic suction column, after the pusher accumulates the iron chips in the cleaning area, the iron chips are affected by the adsorption force of the permanent magnetic suction column. There are certain difficulties in the process of sending the iron chips out of the filter housing, and a large impact force is often required to achieve a better cleaning effect. For this reason, the present invention adopts the following solution: The length of the permanent magnetic column 13 is designed to be smaller than the length of the sleeve and can move up and down in the sleeve. At the same time, an upper channel 14 for penetrating the inner cavity of each sleeve is arranged on the upper partition 10, and a lower channel 15 for penetrating the inner cavity of each sleeve is arranged on the lower partition 11. The matching relationship between the permanent magnetic column 13 and the sleeve is similar to that of a piston cylinder. On this basis, an upper notch 16 for introducing the power medium into the upward channel is provided at the top of the filter housing, and a lower notch 16 for introducing the power medium into the downward channel is provided at the bottom of the filter housing. The lower notch 17 is used to allow a power medium (such as compressed air, hydraulic oil, etc.) to be introduced into the upward channel, thereby driving the permanent magnetic column 13 to move downward in the sleeve. When the permanent magnetic column 13 is away from the upper cleaning area, the power medium can be introduced into the downward channel to drive the permanent magnetic column 13 to move upward in the sleeve. When the permanent magnetic column 13 is away from the lower cleaning area or the lower cleaning area, the problem of difficulty in cleaning caused by the permanent magnetic column 13 adsorbing iron filings in the two areas is effectively eliminated, and vice versa.

[0028] Furthermore, in order to increase the travel of the permanent magnetic column 13 to achieve the best cleaning effect, the upper channel 14 and the lower channel 15 are both stepped holes, and the large diameter section of each stepped hole is equivalent to the diameter of the permanent magnetic column 13 to expand the moving range of the permanent magnetic column, wherein, Figure 6-8As shown, the height of the stepped hole of the upper channel 14 is L1, the height of the stepped hole of the lower channel 15 is L2, the total distance L of L1 and L2 and the length difference between the permanent magnetic column 13 are the movable distance of the permanent magnetic column, and the depth of the upper slot body 6 is equal to the height of the upper partition, and the depth of the lower slot body 7 is equal to the height of the lower partition. At the same time, the top surface of the upper partition 10 can be processed with an upper through groove 27 that penetrates each upper channel 14, and the bottom surface of the lower partition 11 can be processed with a lower through groove 28 that penetrates each lower channel 15. The power medium injected into the upper slot 16 can pass through the upper through groove 27 and then enter the upper channel 14, and the power medium injected into the lower slot 17 can pass through the lower through groove 28 and then enter the lower channel 15. In addition, in order to ensure installation reliability, a limit hole equivalent to the outer diameter of the sleeve can be designed around the stepped hole, and the sleeve can be directly placed in the limit hole 30.

[0029] The propeller 4 mentioned in the present invention may be a screw transmission device, for example: Figure 2 The specific structure of the screw transmission device is given in the figure. As can be seen from the figure, the screw transmission device includes a screw seat 24 located in the filter housing, a screw 25 and two guide rods 26 installed in conjunction with the screw seat. The screw is driven by a drive motor installed outside the filter housing (not shown in the figure). The screw seat 24 is fixedly connected to the pusher 4 through a mounting block. A sensor 20 for detecting the degree of iron filings accumulation is installed on the mounting block, thereby driving the pusher 4 to move up and down. Of course, the device of this pusher 4 can also adopt other structures, such as a hydraulic device, a pneumatic device or an electric propulsion device. In addition, the present invention can also design two rows or even three rows of permanent magnetic adsorption components, thereby better improving the cleaning effect. Such changes all fall within the protection scope of the present invention.

[0030] Here’s how it works: In the initial state, when the liquid containing iron chips flows through the flow channel, the iron chips will inevitably be adsorbed by the permanent magnetic adsorption component; at this time, the pusher 4 moves to the top side of the filter housing and forms an upper isolation flushing chamber, and the permanent magnetic suction column falls into the stepped hole of the lower channel, so that the top of the permanent magnetic suction column is roughly at the position of the lower tank body 7 (see Figure 6 ), then, the magnetic field in the area where the top of the permanent magnetic column is located has a weaker ability to absorb iron chips in the liquid. At the same time, with the help of the pusher 4, the liquid flows through the top position of the permanent magnetic column, and the iron chips gather on the outside of the sleeve. Of course, since the lower end of the permanent magnetic column is inserted into the stepped hole of the lower partition, it does not affect the lower part of the permanent magnetic column to use its magnetic field to absorb iron chips in the liquid; When the waste chip accumulation sensor reaches the set value, a signal is sent, and the propeller drives the pusher to move downward. When the upper edge of the pusher basically reaches the lower edge of the upper partition, a power medium (such as compressed air, hydraulic oil, etc.) is introduced into the downward channel through the lower notch 17 to push the permanent magnetic suction column 2 upward; the total length of the permanent magnetic suction column is preferably designed to be roughly equal to the spacing between the upper partition and the lower partition, so that when the H-shaped part is pushed to the upper end along the casing, the permanent magnetic suction column falls to the bottom of the casing, resulting in no magnetic force around the top of the casing; when the H-shaped part is pushed to the lower end along the casing, the permanent magnetic suction column rises to the top of the casing, resulting in no magnetic force around the lower end of the casing; the reverse movement of the H-shaped part and the permanent magnetic suction column can avoid the disadvantage that the end of the permanent magnetic suction column has weak suction force on iron chips in the liquid; When the pusher continues to move downward with the propeller until the lower edge of the pusher is flush with the end surface of the lower partition, the external hydraulic (or pneumatic) further pushes the permanent magnetic suction column to move upward in the sleeve until it reaches the top of the stepped hole of the upper partition. In addition, the iron filings gathered on the outside of the sleeve are pushed to the partition by the groove of the pusher. The flushing flow channel formed by it can accommodate the excess iron filings, so that the pusher and the lower partition will not be unable to fit together due to the existence of iron filings, which can better ensure the use effect; At this time, the filtration system continues to operate, and the fluid containing iron filings continues to be adsorbed and filtered through the upper and middle parts of the permanent magnetic column.

[0031] An external strong fluid system such as high-pressure water passes through the square hole (lower connecting port) on one side of the lower part of the filter housing. The lower connecting port is connected to the flushing pipe and the flushing valve. By passing high-pressure water into the lower isolation flushing chamber, the accumulated iron filings are pushed along the lower trough body to the outside.

[0032] After completing one cycle, close the external filter and close the square holes on both sides of the lower part of the shell (lower communication ports) through the flushing valve.

[0033] When enough iron chips accumulate on the permanent magnetic suction column, the sensor sends a signal, and the propeller drives the pusher upward to carry out the next round of automatic chip removal operation, realizing the process of continuous filtration and automatic chip removal.

[0034] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
