Description

Technical Field

[0001] This utility model relates to the field of steel strip processing technology, and in particular to a cleaning fluid magnetic filter device used in steel strip production. Background Technology

[0002] During strip steel processing, strip steel of a certain thickness needs to be rolled to change its width to meet production requirements. However, during the rolling process, a large amount of iron powder, iron filings, iron particles, oxide scale, rust layer and other contaminants are generated on the surface of the strip steel. In the production process, when hot-rolled strip steel is cold-rolled after pickling, the strip steel has a high resistance to deformation at room temperature, requiring the use of cleaning fluid for cleaning, cooling and lubrication. Most of the iron powder on the surface of the steel strip enters the cleaning fluid, which is recycled. The iron powder and other impurities in the cleaning fluid can scratch the coating on the surface of the strip steel, affecting the appearance and processing quality of the strip steel. Therefore, it is necessary to treat the recycled cleaning fluid to remove iron impurities.

[0003] Patent CN221016578U discloses a device for removing iron impurities from a cleaning solution. The device includes a frame with a drive shaft connected to a motor on it. A storage tank is located below the drive shaft, and a driven shaft is located within the storage tank. Both the drive and driven shafts are horizontally positioned, and each shaft has a rotating frame. The two rotating frames are rotatably connected by several magnetic chains. The frame is equipped with a scraping device for removing iron impurities from the magnetic chains. By continuously moving the magnetic chains in and out of the storage tank, iron powder and other impurities in the cleaning solution are adsorbed onto the magnetic chains, and the iron powder is scraped off from above the storage tank.

[0004] However, in actual applications, as the equipment operates for a long time, wear can easily occur at the hinge of the magnetic chain, causing the originally tense magnetic chain in the equipment to loosen. Since the magnetic chain itself has strong magnetism, two adjacent loosened magnetic chains are easily attracted to each other or even completely come into contact and adsorb during the process of being lifted upward from the liquid storage tank. This can easily cause the magnetic chain to touch the edge of the chain groove of the matching magnetic chain on the rotating frame, accelerating the wear of the rotating frame. In severe cases, it can even cause the magnetic chain to break or damage the motor equipment. Utility Model Content

[0005] In view of the above problems, this utility model provides a cleaning fluid magnetic filter device for use in steel strip production.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0007] A magnetic filtering device for cleaning fluid used in steel strip production is provided, comprising a cleaning tank filled with cleaning fluid, a support frame installed inside the cleaning tank, a rotating roller horizontally mounted on the support frame, the two ends of the rotating roller being rotatably connected to the support frame, two rotating rollers arranged parallel to each other in the vertical direction, the two rotating rollers being located above and below the surface of the cleaning fluid in the cleaning tank respectively, a magnetic chain wound around the two rotating rollers, and multiple slots evenly spaced along their own axial direction on the rotating rollers for cooperating with the magnetic chain, a driving component for driving the rotation of any one of the rotating rollers on the support frame, a cleaning component for collecting iron powder on one side of the magnetic chain on the support frame, and a guide component on the other side, the cleaning component being located above the surface of the cleaning fluid, and the guide component being located below the higher rotating roller, the guide component being used to guide the magnetic chain.

[0008] Furthermore, the cleaning component includes a collection tank and a scraping sleeve. The collection tank is fixedly mounted on the support frame and has an outlet that extends to the outside of the cleaning tank. The scraping sleeve is fixedly mounted inside the collection tank. The magnetic chain includes several magnetic joint units with circular cross-sections. The scraping sleeve has through holes that are adapted to the magnetic joint units.

[0009] Furthermore, the guide component includes guide rods, which are vertically fixed on the side wall of the support frame. Multiple guide rods are arranged horizontally along the axial direction of the rotating roller and spaced apart. The magnetic chain passes through the gap between two adjacent guide rods. The guide rods are made of a material that is not magnetically attracted.

[0010] Furthermore, the guide component includes a guide sleeve, which is fixedly mounted on the support frame. Multiple guide sleeves are horizontally spaced apart, and each guide sleeve corresponds to a magnetic chain. The magnetic chain passes through the guide sleeve, and the lower part of the guide sleeve forms a guide skirt that is smaller at the top and larger at the bottom.

[0011] Furthermore, the magnetic joint unit includes a magnetic rod and two connectors. The two connectors are detachably mounted at both ends of the magnetic rod. The two connectors of two adjacent magnetic joint units are hinged together. The connectors are made of a material that is not magnetically attracted.

[0012] Furthermore, connecting posts are coaxially fixed at both ends of the magnetic rod, and connecting grooves adapted to the connecting posts are opened on the connecting head. A first through hole is opened on the connecting post along its own radial direction, and a second through hole is opened on the connecting head along its own radial direction. The connecting head is detachably connected to the connecting post by bolts. The bolt passes through the first through hole and the second through hole and is threadedly connected to the nut. A countersunk groove for accommodating the bolt head and the nut is opened on the outer wall of the connecting head.

[0013] The beneficial effects of this utility model are as follows: by setting a guide at the position where the magnetic chain is lifted out of the cleaning liquid surface, the guide guides each magnetic chain before the magnetic chain winds around the rotating roller. Even if adjacent magnetic chains loosen and attract each other, the guide can still separate the two magnetic chains, forcing the magnetic chains to align with the grooves on the rotating roller, so that the magnetic chains can be neatly and stably wound in the grooves, avoiding collision between the edge of the groove and the magnetic chain, which would cause wear on the rotating roller or magnetic chain, and extending the service life of the device.

Detailed Implementation

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] Example 1

[0021] This application discloses a cleaning fluid magnetic filter device used in steel strip production, referring to... Figure 1 and Figure 2The system includes a cleaning tank 1 filled with cleaning fluid. An inlet pipe and an outlet pipe can be connected to the outer wall of the cleaning tank 1 to perform magnetic filtration on the cleaning fluid used online. A support frame 2 is fixedly installed inside the cleaning tank 1. A rotating roller 3 is horizontally mounted on the support frame 2, with both ends of the roller 3 rotatably connected to the support frame 2. Two rotating rollers 3 are arranged parallel to each other in the vertical direction on the support frame 2, located above and below the surface of the cleaning fluid in the cleaning tank 1, respectively. A magnetic chain 4 is wound around the two rotating rollers 3. Multiple slots 31 are evenly spaced along the axial direction of each rotating roller 3 to engage with the magnetic chain 4. A drive component 5 is provided on the support frame 2 to drive the rotation of either rotating roller 3. The magnetic chain 4 is magnetic; as it rotates with the rotating roller 3, it continuously enters and exits the cleaning fluid, thereby adsorbing impurities such as iron powder in the cleaning fluid onto the surface of the magnetic chain 4. A cleaning component and a guide component are provided on the support frame 2 above the surface of the cleaning fluid, located on opposite sides of the support frame 2. Specifically, the guide is located on the side of the support frame 2 where the magnetic chain 4 rises, and below the higher rotating roller 3, for guiding the magnetic chain 4. The cleaning component is located on the side of the support frame 2 where the magnetic chain 4 falls, for removing iron powder magnetically adsorbed on the surface of the magnetic chain 4.

[0022] In this embodiment, the magnetic chain 4 is composed of several circular magnetic joint units 41 hinged end to end. The cleaning component mainly consists of a collection tank 61 and a scraping sleeve 62. The collection tank 61 can be fixed to the support frame 2 by welding or other means. An outlet is provided on the side wall of the collection tank 61, and the outlet of the collection tank 61 extends to the outside of the cleaning tank 1. The scraping sleeve 62 is fixedly installed in the collection tank 61. The scraping sleeve 62 has a through hole adapted to the magnetic joint unit 41. Before the magnetic chain 4 enters the cleaning liquid, it passes through the scraping sleeve 62. The scraping sleeve 62 scrapes off the iron powder adsorbed on the surface of the magnetic chain 4 and collects it in the collection tank 61. The iron powder collected in the collection tank 61 is processed by the staff periodically.

[0023] In this embodiment, the guide includes guide rods 71, which are vertically fixed on the side wall of the support frame 2. Multiple guide rods 71 ​​are horizontally spaced along the axial direction of the rotating roller 3, and the magnetic chain 4 passes through the gap between adjacent guide rods 71. The guide rods 71 ​​are made of a non-magnetically attracted material, such as PC tubing, wooden rods, or aluminum rods, which effectively separates mutually attracted magnetic chains 4. Before the magnetic chain 4 rises to contact the upper rotating roller 3, the guide rods 71 ​​separate and guide the magnetic chain 4, allowing it to accurately align with the groove 31 on the rotating roller 3. This reduces collisions between the magnetic chain 4 and the edge of the groove 31 as the rotating roller 3 drives the magnetic chain 4.

[0024] Each magnetic segment unit 41 of the magnetic chain 4 is cylindrical. In order for the rotating roller 3 to smoothly drive the magnetic chain 4, the cross-sectional shape of the rotating roller 3 can be polygonal, so that each magnetic segment unit 41 can be fitted into the groove 31 on each side of the rotating roller 3. The driving component 5 can be a motor, which is fixedly mounted on the support frame 2, and the output shaft of the motor is connected to the rotating shaft of the upper layer of the rotating roller 3.

[0025] Furthermore, each magnetic joint unit 41 includes a magnetic rod 411 and two connectors 412, which are detachably connected to both ends of the magnetic rod 411. The two connectors 412 of adjacent magnetic joint units 41 are hinged together, and both connectors 412 can be made of a non-magnetically attracted material, such as PC or aluminum. When the scraping sleeve 62 scrapes iron powder from the surface of the magnetic joint unit 41, the iron powder is pushed to the connector 412. Losing the magnetic support of the magnetic rod 411, the iron powder naturally slides off the outside of the scraping sleeve 62, improving the scraping effect of the scraping sleeve 62 on the iron powder on the magnetic chain 4. Moreover, by using detachable connectors 412 and magnetic rods 411, when wear occurs at the hinge of the connector 412 causing the magnetic chain 4 to loosen, the operator can remove the connector 412 from the magnetic rod 411 and replace it, extending the service life of the device.

[0026] Specifically, the connector 412 is detachably connected to the magnetic rod 411 by bolts 415. Both ends of the magnetic rod 411 are coaxially and integrally fixedly connected to connecting posts 413. The connecting posts 413 have a first through hole along their own radial direction. The connector 412 has a connecting groove 414, which is adapted to the connecting posts 413, so that the connector 412 can accurately match the connecting posts 413. The side wall of the connector 412 has a second through hole along its own radial direction. When the connecting posts 413 and the connecting groove 414 are engaged, the first through hole aligns with the second through hole. After the bolts 415 pass through the first and second through holes, they are connected to the nuts 416, thereby connecting and fixing the connector 412 and the magnetic rod 411.

[0027] Furthermore, in order to allow the magnetic joint unit 41 to pass smoothly through the scraping sleeve 62, a groove 417 is provided on the outer wall of the connector 412 to accommodate the head of the bolt 415 and the nut 416. After the bolt 415 connects and fixes the connector 412 and the magnetic rod 411, the bolt 415 and the nut 416 do not protrude from the outer surface of the magnetic rod 411, so that the scraping sleeve 62 can smoothly remove the iron powder from the surface of the magnetic rod 411.

[0028] Example 2

[0029] The difference between Example 2 and Example 1 is that the structure of the guide is different.

[0030] In this embodiment, the guide component can be a guide sleeve 701. The guide sleeve 701 is welded and fixed to the support frame 2 via connecting pieces. The number of guide sleeves 701 corresponds one-to-one with the number of magnetic chains 4. The guide sleeve 701 is sleeved on the outside of each magnetic chain 4, and the lower part of the guide sleeve 701 forms a guide skirt 702 that is smaller at the top and larger at the bottom. When the magnetic chain 4 rises, under the guiding action of the guide skirt 702, the two magnetic chains 4 that are attracted together can be separated more effectively, improving the guiding and separating effect of the guide component on the magnetic chains 4.
