Description

Technical Field

[0001] This utility model relates to the field of iron removal device technology, and more specifically, to a drawer self-cleaning iron remover. Background Technology

[0002] Powders are widely used in industries such as lithium batteries, abrasives, and chemicals. During processing and transportation, iron filings can easily get mixed into the powder. Powders containing iron filings will reduce product quality and cause damage to equipment. Therefore, when the powder is fed into the processing equipment, it is necessary to remove the iron filings and iron powder through a drawer iron separator.

[0003] The existing drawer-type iron remover includes a housing, a magnetic rod, and a scraper. The housing is divided into a powder feeding chamber and a cleaning chamber by a partition. The scraper is fitted onto the magnetic rod and located in the cleaning chamber. The scraper slides synchronously with the magnetic rod through friction. A through-hole for the magnetic rod to pass through is provided on the partition. The scraper is larger than the through-hole. The magnetic rod moves under the action of a drive mechanism and is positioned in the powder feeding chamber. When the powder passes through the powder feeding chamber, iron filings in the powder are attracted by the magnetic rod. At this time, the scraper moves to the through-hole under the action of friction, blocking the through-hole and preventing powder from entering the cleaning chamber. When it is necessary to remove iron filings from the magnetic rod, the drive mechanism moves the magnetic rod to the cleaning chamber. During this process, the scraper moves synchronously with the magnetic rod under the action of friction. When the scraper abuts against the wall of the cleaning chamber, it stops moving, while the magnetic rod continues to move, and the scraper scrapes off the iron filings from the magnetic rod.

[0004] However, some manufacturers use long pipelines to transport powder. To ensure smooth powder flow within these pipelines, positive pressure is typically applied, creating a positive pressure environment in the powder discharge chamber. However, because the scraper relies solely on friction with the magnetic rod to seal the through-hole, the sealing effect is poor. When the cleaning chamber is at atmospheric pressure, while the powder discharge chamber is under positive pressure exceeding the friction between the scraper and the magnetic rod, the scraper will be pushed open, causing powder to enter the cleaning chamber and leak. Utility Model Content

[0005] To address at least one of the aforementioned problems, this utility model provides a drawer self-cleaning iron remover, comprising a housing, a magnetic rod assembly, and a scraper assembly. The housing has a first partition spaced inside, forming a first chamber and a second chamber within the housing via the first partition. The first chamber is suitable for passing through powder. A driving member is provided outside the housing, connected to the magnetic rod assembly, to drive the magnetic rod assembly to move from the first chamber to the second chamber. A through-hole is provided on the first partition, communicating with both the first chamber and the second chamber. The magnetic rod assembly is adapted to be inserted into the through-hole. The scraper assembly is connected to the magnetic rod assembly and is adapted to cover and seal the through-hole. The magnetic rod assembly includes a push rod. When the magnetic rod assembly moves into position in the first chamber and the scraper assembly covers the through-hole, the driving member drives the push rod to press the scraper assembly against the first partition.

[0006] Optionally, the scraper assembly includes a first scraper ring, a mounting plate, and a sealing gasket sleeved on the magnetic rod assembly. The first scraper ring is connected to the mounting plate and fits tightly against the magnetic rod assembly, suitable for scraping off iron filings adsorbed on the magnetic rod assembly. The sealing gasket is connected to the side of the mounting plate near the first partition. The push rod is suitable for driving the sealing gasket to press against the first partition to seal the through hole.

[0007] Optionally, the magnetic rod assembly further includes a sliding plate and a magnetic rod body, the magnetic rod body being fixedly connected to the sliding plate, the sliding plate being connected to the driving component, the first scraper ring being made of an elastic material, the first scraper ring being tightly fitted onto the magnetic rod body, and the top rod being fixedly connected to the sliding plate.

[0008] Optionally, the magnetic rod body includes a magnetic section and a non-magnetic section. The non-magnetic section has two segments, which are located at both ends of the magnetic rod body. The magnetic section is located in the middle of the magnetic rod body. The first scraping ring is adapted to scrape the iron filings adsorbed by the magnetic section to the non-magnetic section.

[0009] Optionally, the scraper assembly further includes a limiting plate. The mounting plate has a mounting hole on the side near the sealing gasket. The first scraper ring is inserted into the mounting hole. The limiting plate is located on the side of the mounting plate near the sealing gasket and is fixedly connected to the mounting plate. The limiting plate is adapted to limit the first scraper ring within the mounting hole. The sealing gasket is fixedly connected to the side of the limiting plate near the first partition.

[0010] Optionally, the sealing gasket is fitted onto the magnetic rod body and fits tightly against the magnetic rod body.

[0011] Optionally, multiple magnetic rods are spaced apart on the sliding plate, and the number of the first scraping rings is the same as the number of magnetic rods and corresponds one-to-one.

[0012] Optionally, the second chamber is provided with a second partition, and the second chamber forms a cleaning chamber and a sliding chamber through the second partition. The cleaning chamber is located between the first chamber and the sliding chamber. The scraper assembly slides in the cleaning chamber, and the sliding plate slides in the sliding chamber. The sliding stroke of the sliding plate is greater than the sliding stroke of the scraper assembly.

[0013] Optionally, the second partition has a through hole through which the magnetic rod body passes, and a second scraper ring is fixedly provided at the through hole. The second scraper ring is tightly fitted onto the magnetic rod body and is adapted to clean the magnetic rod body again after it has been cleaned by the first scraper ring.

[0014] Optionally, a fixing plate is fixedly installed at the end of the magnetic rod body away from the sliding plate, and multiple magnetic rod bodies are connected to the fixing plate.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0016] 1. The magnetic rod assembly itself needs to be driven by the driving component to move. When the magnetic rod assembly moves into place in the first chamber, the scraper assembly will also abut against the first partition to block and seal the through hole. At this time, the push rod can press the scraper assembly against the first partition under the drive of the driving component. Even if there is positive pressure in the first chamber, the scraper assembly will not move, thus forming a high sealing performance.

[0017] 2. After the scraper assembly is pressed against the first partition plate by the top rod, the sealing gasket is pressed against the first partition plate directly, which further improves the sealing effect at the through hole. When the first chamber is under positive pressure, the powder will not enter the second chamber, thus preventing powder leakage.

[0018] 3. The first scraper ring is made of elastic material, and after the first scraper ring and the sealing gasket are fitted onto the magnetic rod body, they are tightly fitted to the magnetic rod body, so that a double seal is formed at the contact point with the magnetic rod body. Powder is also less likely to enter the second chamber from between the first scraper ring and the magnetic rod body, which further improves the sealing performance between the first chamber and the second chamber and is suitable for various working conditions.

[0019] 4. Since the scraper assembly moves less in the cleaning chamber than the sliding plate moves in the sliding chamber, it will be stopped when it comes into contact with the second partition, while the magnetic rod body can continue to move. Therefore, the scraper assembly can automatically scrape off the iron filings adsorbed on the magnetic rod body, thereby achieving a self-cleaning effect and improving the convenience of cleaning.

[0020] 5. When scraping iron filings off the magnetic rod body, the first scraping ring and the second scraping ring form a dual cleaning effect. If the first scraping ring is too worn to clean the iron filings off the magnetic rod body, the second scraping ring will clean again, thereby improving the cleaning effect.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-6 This application will be described in further detail.

[0029] The accompanying drawings of this utility model embodiment provide a coordinate system XYZ, where the positive direction of the X-axis represents the right, the negative direction of the X-axis represents the left, the positive direction of the Y-axis represents the front, the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom.

[0030] This utility model embodiment provides a drawer self-cleaning iron remover, see reference. Figure 1 and Figure 2The drawer self-cleaning iron remover includes a housing 1, a magnetic rod assembly 2, and a scraper assembly 3. A first partition 11 is spaced inside the housing 1, forming a first chamber 12 and a second chamber. The first chamber 12 is suitable for passing through powder. A driving member 13 is provided outside the housing 1, connected to the magnetic rod assembly 2, to drive the magnetic rod assembly 2 to move from the first chamber 12 to the second chamber, or from the second chamber to the first chamber 12. A through hole 111 is provided on the first partition 11, communicating with both the first chamber 12 and the second chamber. The magnetic rod assembly 2 is suitable for insertion into the through hole 111. The scraper assembly 3 is connected to the magnetic rod assembly 2, suitable for sealing the through hole 111, and for scraping away iron filings adsorbed on the magnetic rod assembly 2 within the second chamber. When the magnetic rod assembly 2 moves into position in the first chamber 12 and the scraper assembly 3 blocks the through hole 111, the magnetic rod assembly 2 is also adapted to press the scraper assembly 3 against the first partition 11. Even if there is positive pressure in the first chamber 12, the scraper assembly 3 will not move, thereby forming a high degree of sealing.

[0031] The outer shell 1 is formed by splicing multiple plates together and fixing them with bolts, which improves the convenience when maintenance, repair or replacement of parts is required.

[0032] Reference Figure 2 and Figure 3 The first chamber 12 and the second chamber are arranged in a left-right direction, with the second chamber located to the right of the first chamber 12. A powder inlet is located at the top of the first chamber 12, and a powder outlet is located at the bottom. Powder enters the first chamber 12 through the powder inlet via a pipe and then flows out through the powder outlet. As the powder passes through the first chamber 12, the magnetic rod assembly 2, located inside the first chamber 12, attracts iron filings from the powder. At this time, the scraper assembly 3 seals and blocks the through hole 111.

[0033] A second partition 14 is fixedly installed in the second chamber, forming a cleaning chamber 15 and a sliding chamber 16. The cleaning chamber 15 is located between the first chamber 12 and the sliding chamber 16. A discharge port for iron filings to fall off is provided at the bottom of the cleaning chamber 15. The scraper assembly 3 slides within the cleaning chamber 15. One side of the magnetic rod assembly 2 is located within the sliding chamber 16 and slides within it. The other side passes through the second partition 14 and the first partition 11, making it suitable for adsorbing iron filings in the powder within the first chamber 12. The stroke of the scraper assembly 3 within the cleaning chamber 15 is less than the stroke of the magnetic rod assembly 2 within the sliding chamber 16. Thus, when the scraper assembly 3 comes into contact with the second partition 14, it will be limited, while the magnetic rod assembly 2 can still continue to move. Therefore, the scraper assembly 3 can automatically scrape off the iron filings adsorbed on the magnetic rod assembly 2, thereby achieving a self-cleaning effect.

[0034] Reference Figure 2 and Figure 3 The magnetic rod assemblies 2 are arranged in at least two sets at intervals along the vertical direction, thereby forming a multiple adsorption effect on iron filings in the powder and improving the adsorption effect. The number of driving components 13 is the same as the number of magnetic rod assemblies 2 and corresponds one-to-one. In this way, if any set of magnetic rod assemblies 2 is damaged, it will not affect the operation of the remaining magnetic rod assemblies 2. In this embodiment, three sets of magnetic rod assemblies 2 are preferably arranged, and the three sets of magnetic rod assemblies 2 have the same structure. The following description uses the structure of one set of magnetic rod assemblies 2 as an example.

[0035] Reference Figures 2 to 4 The magnetic rod assembly 2 includes a push rod 21, a sliding plate 22, and a magnetic rod body 23. The sliding plate 22 slides in the sliding cavity 16 in a left-right direction. In this embodiment, the driving component 13 is preferably a cylinder. The cylinder body is fixedly installed outside the outer shell 1, and the telescopic rod of the cylinder is inserted into the sliding cavity 16 and fixedly connected to the sliding plate 22, thereby driving the sliding plate 22 to move. The push rod 21 is fixedly installed on the side of the sliding plate 22 near the cleaning cavity 15. The push rod 21 is adapted to press the scraper assembly 3 against the first partition 11. Multiple push rods 21 are arranged at intervals, and the multiple push rods 21 press against different positions on the periphery of the scraper assembly 3. The magnetic rod body 23 is fixed to the side of the sliding plate 22 near the cleaning cavity 15 by bolts. The magnetic rod body 23 is adapted to adsorb iron filings in the powder.

[0036] A guide rod is fixedly installed inside the sliding cavity 16. The sliding plate 22 is sleeved on the guide rod and slides in a directional manner. The sliding stroke of the sliding plate 22 is greater than that of the scraper assembly 3. Multiple magnetic rod bodies 23 are provided, and the multiple magnetic rod bodies 23 are arranged at intervals along the front-back direction on the sliding plate 22 to improve the adsorption effect on iron filings in the powder. The end of the magnetic rod body 23 away from the sliding plate 22 is fixedly installed with a fixing plate 24 by bolts. All the magnetic rod bodies 23 are connected to the fixing plate 24, thereby ensuring the concentricity of the multiple magnetic rod bodies 23 on the same sliding plate 22 and making the movement smoother. The magnetic rod bodies 23 in two adjacent sets of magnetic rod assemblies 2 are arranged alternately along the front-back direction, thereby increasing the coverage area of ​​the powder and improving the adsorption effect.

[0037] Reference Figures 3 to 5 The magnetic rod body 23 includes a magnetic section and a non-magnetic section. The non-magnetic section has two segments, located at both ends of the magnetic rod body 23, while the magnetic section is located in the middle of the magnetic rod body 23. When the magnetic section is in the first chamber 12, it is suitable to completely cover the powder inlet (i.e., the length of the magnetic section is greater than the inner diameter of the powder inlet), so that the powder can completely pass through the magnetic section during the flow process. The non-magnetic section, while ensuring the connection between the magnetic rod body 23 and the scraper assembly 3, allows the scraper assembly 3 to scrape the iron filings from the magnetic section to the non-magnetic section, so that the iron filings can automatically fall into the cleaning chamber 15 and be discharged through the discharge port.

[0038] Since there are multiple sets of magnetic rod assemblies 2, there are also multiple sets of scraper assemblies 3. The number of scraper assemblies 3 is the same as the number of magnetic rod assemblies 2 and they correspond one-to-one. The following explanation uses one set of scraper assemblies 3 as an example.

[0039] Reference Figures 3 to 6 The scraper assembly 3 includes a first scraper ring 31, a mounting plate 32, a sealing gasket 33, and a limiting plate 34. The first scraper ring 31 is clamped between the mounting plate 32 and the limiting plate 34. The limiting plate 34 is located on the side of the mounting plate 32 near the first partition 11, and the limiting plate 34 and the mounting plate 32 are fixedly connected. The sealing gasket 33 is fixedly connected to the limiting plate 34 on the side near the first partition 11 by adhesive. The push rod 21 is adapted to drive the sealing gasket 33 to press against the first partition 11 to seal the through hole 111. The number of first scraper rings 31 is the same as the number of magnetic rod bodies 23 and corresponds one-to-one. The first scraper rings 31 are made of elastic material and are tightly fitted onto the magnetic rod bodies 23, suitable for scraping off iron filings adsorbed on the magnetic rod bodies 23. The mounting plate 32, the sealing gasket 33, and the limiting plate 34 are all fitted onto multiple magnetic rod bodies 23.

[0040] The mounting plate 32 has mounting holes on the side near the limiting plate 34, the same number as the number of first scraper rings 31. Each first scraper ring 31 is inserted into a corresponding mounting hole. The bottom of each mounting hole has a first through hole for inserting the magnetic rod body 23. The diameter of the first through hole is smaller than the outer diameter of the first scraper ring 31, thus ensuring the first scraper ring 31 is fixedly connected to the mounting plate 32 and is less likely to fall out of the first through hole. The limiting plate 34 has a second through hole for the magnetic rod body 23 to pass through. The inner diameter of the second through hole is smaller than the diameter of the mounting hole, thus the limiting plate 34 is suitable for confining the first scraper ring 31 within the mounting hole. The diameters of both the first and second through holes are larger than the outer diameter of the magnetic rod body 23, preventing the mounting plate 32 and the limiting plate 34 from contacting the magnetic rod body 23 and forming rigid friction.

[0041] Reference Figures 3 to 6 The limiting plate 34 is fixedly provided with multiple threaded posts at intervals on the side near the mounting plate 32. The multiple threaded posts pass through the mounting plate 32 and are threadedly connected to the nut, thereby fixing the limiting plate 34 and the mounting plate 32 and clamping the first scraper ring 31.

[0042] The sealing gasket 33 is fitted onto the magnetic rod body 23 and fits tightly against the magnetic rod body 23, so that the sealing gasket 33 and the magnetic rod body 23 form a seal at the contact point, which improves the sealing performance between the first chamber 12 and the cleaning chamber 15.

[0043] Reference Figures 3 to 6The second partition 14 has through holes for the magnetic rod body 23 to pass through, and the number of through holes is the same as the number of magnetic rod bodies 23, with each hole corresponding to the first. A second scraper ring 17 is provided at each through hole, located within the sliding cavity 16 and fitting snugly against the second partition 14. A bolt post is fixedly provided on the side of the second partition 14 near the sliding cavity 16, and a clamping plate 18 is provided on the side of the second scraper ring 17 near the sliding cavity 16. The clamping plate 18 is sleeved on the bolt post, and a nut is provided on the bolt post. The nut drives the clamping plate 18 to press the second scraper ring 17 against the second partition 14 for fixation. The magnetic rod body 23 is adapted to pass through the second scraper ring 17, which is made of elastic material and tightly fitted onto the magnetic rod body 23. The second scraper ring 17 is suitable for cleaning the magnetic rod body 23 again after it has been cleaned by the first scraper ring 31, thereby improving the cleaning effect. When the magnetic rod body 23 moves from the first chamber 12 into the cleaning chamber 15 and moves to the limit position, both the first scraper ring 31 and the second scraper ring 17 are in the non-magnetic section.

[0044] The implementation principle of the drawer self-cleaning iron remover in this embodiment is as follows: Since the first scraper ring 31 is made of elastic material and is tightly fitted onto the magnetic rod body 23, when the driving member 13 drives the sliding plate 22 to move the magnetic rod body 23 into the first chamber 12, and the sealing gasket 33 is not in contact with the first partition 11, the entire scraper assembly 3 will move under the action of the frictional resistance between the first scraper ring 31 and the magnetic rod body 23. Since the stroke of the scraper assembly 3 is less than the stroke of the magnetic rod body 23, when the sealing gasket 33 abuts against the first partition 11, the movement of the entire scraper assembly 3 is limited, while the sliding plate 22 and the magnetic rod body 23 can still continue to move. When the entire magnetic section is completely located in the first chamber 12, the top rod 21 will press against the mounting plate 32 to make the sealing plate tightly fit against the first partition 11. Since the push rod 21 is directly driven by the drive component 13 to move, the first chamber 12 is under positive pressure and the cleaning chamber 15 is under normal pressure. Therefore, the scraper assembly 3 will not move due to the pressure difference, and has good sealing performance.

[0045] When it is necessary to remove iron filings from the magnetic rod body 23, the powder and positive pressure airflow in the pipeline are stopped. The drive unit 13 drives the sliding plate 22 to move away from the cleaning chamber 15, while the entire scraper assembly 3 moves under the frictional resistance of the first scraper ring 31 and the magnetic rod body 23. When the end of the threaded column abuts against the second partition 14, the entire scraper assembly 3 stops moving, but the magnetic rod body 23 can still continue to move. The sealing gasket 33 and the first scraper ring 31 will then scrape the iron filings attracted by the magnetic segment to the non-magnetic segment, where the iron filings will automatically fall off. At the same time, the second scraper ring 17 is suitable for cleaning the magnetic rod body 23 again after it has been cleaned by the first scraper ring 31, thereby improving the cleaning effect. In this way, self-cleaning is achieved.
