Description

Technical Field

[0001] The utility model relates to the technical field of iron removal devices, in particular to a double-sealed powder automatic drawer-type iron remover. Background Art

[0002] In the fields of ceramics, abrasives, ore powder, papermaking, chemicals, etc., the powder itself may carry particles such as iron filings, and iron filings may also be mixed in during processing and storage. The presence of iron filings will reduce the quality of the product and damage the processing equipment. Therefore, an iron removal device is required to remove iron.

[0003] Patent application number 202321048311.6 proposes a fully enclosed automatic cleaning iron remover, which has the following problems: 1. The magnetic rod in the patent includes a non-magnetic section and a magnetic section. By driving the magnetic rod, the magnetic impurities adsorbed on the magnetic section are brought to the slag discharge area, and the force adsorbing the magnetic impurities disappears through the non-magnetic section, causing the magnetic impurities to fall and discharge. However, after a period of use, the non-magnetic section will be magnetized by the magnetic section (magnetic section). After magnetization, the non-magnetic section also has a certain magnetism, resulting in the magnetic impurities still being adsorbed by the non-magnetic section (after magnetization) during slag removal, resulting in the magnetic impurities not being easy to fall off or not being able to fall off completely, thereby resulting in low iron removal efficiency and incomplete iron removal; 2. A gap is formed between the sleeve and the partition in the patent, and iron powder impurities move from the iron removal area to the slag discharge area through the gap. However, during normal material discharge, part of the material (non-magnetic) will move from the iron removal area through the gap to the slag discharge area for "slag discharge", resulting in the mixing of materials and impurities and waste of materials, resulting in a poor user experience.

[0027] See Figures 1-8The embodiment of the present invention provides a double-sealed powder automatic drawer-type iron remover, comprising: a shell 1, which is arranged on a frame 8; a feed port 101 is provided at the upper end of the shell 1, and the feed port 101 is used to put in powder materials mixed with magnetic impurities such as iron powder; a material discharge port 102 and a slag discharge port 103 are provided at the lower end of the shell 1, the material discharge port 102 is used to discharge the demagnetized material, and the slag discharge port 103 is used to discharge the slag material with magnetic impurities. An inner cavity and a partition 2 are provided in the shell 1, and the partition 2 separates the inner cavity into an iron removal area 104 and a slag discharge area 105, the feed port 101 is communicated with the upper side of the iron removal area 104, the material discharge port 102 is communicated with the lower side of the iron removal area 104, and the slag discharge port 103 is communicated with the lower side of the slag discharge area 105, a magnetic rod group 3 and a driving component for driving the magnetic rod group 3 to slide axially are provided on the shell 1, one end of the magnetic rod group 3 sequentially passes through the side wall of the shell 1 and the partition 2, and the magnetic rod group 3 includes a magnetic rod 31, and a first through hole 201 for the magnetic rod 31 to pass through is opened on the partition 2. The magnetic rod 31 includes a first magnetic rod segment 311 placed in the iron removal area 104 and a second magnetic rod segment 312 placed in the slag discharge area 105. The first magnetic rod segment 311 has magnetic force, and the second magnetic rod segment 312 can be magnetic or non-magnetic. A sliding sleeve 4 is provided on the magnetic rod 31, and magnetic impurities on the magnetic rod 31 are scraped away by the spacer sleeve 4. The spacer sleeve 4 is placed in the slag discharge area 105. A sealing portion 401 for sealing the first through hole 201 is provided at one end of the spacer sleeve 4 close to the partition 2 to prevent cross-contamination between the iron removal area and the slag discharge area during demagnetization. The double-sealed powder automatic drawer type iron remover of the utility model is not prone to cross-contamination between the iron removal area and the slag discharge area during demagnetization; the magnetic impurities on the magnetic rod are scraped away by the spacer sleeve, and the demagnetization is cleaner and more thorough, with good use effect; automatic demagnetization is achieved through the driving component, thereby improving demagnetization efficiency and reducing labor costs.

[0028] The working principle of this iron remover is as follows: 1. During demagnetization, the magnetic rods 31 are pushed into the inner cavity. At this time, the spacer sleeve 4 is attached to one side of the partition 2 to block the first through hole 201, and the material is fed in through the feed port 101. At this time, the magnetic impurities in the material are adsorbed by the first magnetic rod segment 311, and the removed material is discharged from the material outlet 102; 2. When it is necessary to discharge slag from one or several magnetic rods after demagnetization for a certain period of time, the corresponding magnetic rod is pulled out of the shell cavity to one side through the driving component. At this time, the pulled magnetic rod first drives the spacer sleeve on it to move synchronously, and the magnetic impurities on the magnetic rod are displaced through the first through hole to the slag discharge area 105. When the spacer sleeve moves to against the shell, the magnetic rod is continued to be pulled out. The magnetic rod and the spacer sleeve slide relative to each other, and the spacer sleeve scrapes the magnetic impurities on the magnetic rod. When the magnetic rod is pulled out into place, the magnetic impurities on the magnetic rod are scraped by the spacer sleeve and fall to the slag outlet 103 for discharge; 3. When the corresponding magnetic rod completes slag discharge, it is reset by the driving component to continue the demagnetization work.

[0029] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 and Figure 8 , the spacer 4 and the magnetic rod 31 are clearance-matched, so that the magnetic rod 31 can drive the spacer 4 to slide synchronously, and when the spacer 4 encounters a limit, the magnetic rod 31 and the spacer 4 can slide relative to each other; the blocking portion 401 is an annular flange, and the outer diameter of the annular flange is larger than the aperture of the first through hole 201, so that the blocking portion 401 can offset and block the first through hole 201, and it is not easy to cause material cross-contamination; the spacer 4 is made of polytetrafluoroethylene, and polytetrafluoroethylene has the advantages of excellent chemical stability, corrosion resistance, sealing, high lubrication and non-stickiness, so that the spacer 4 can slide relatively more smoothly with the magnetic rod 31, and the sealing effect of the spacer 4 when blocking the first through hole is good; along the axial direction of the magnetic rod 31, the first length L of the spacer 4 is less than the second length M of the slag discharge area 105, so that the spacer 4 has a certain displacement space, so that the blocking state of the first through hole can be released during slag removal, allowing magnetic impurities to be displaced into the slag discharge area 105 through the first through hole, and the structural design is reasonable.

[0030] See Figure 1-Figure 3 , a second through hole 106 is provided on the shell 1 for the magnetic rod 31 to pass through, and a sealing ring 5 is provided on the shell 1 for sealing the second through hole 106 to prevent magnetic impurities in the slag discharge area 105 from leaking out of the shell through the second through hole 106, which is reliable to use. At the same time, the sealing ring can also scrape the magnetic impurities on the magnetic rod again, making the slag discharge more thorough and improving the demagnetization efficiency; the sealing ring 5 is placed on the side of the second through hole 106 away from the partition; the spacer 4 includes a circular column 41, and the aperture of the second through hole 106 is smaller than the outer diameter of the circular column 41. When slag is discharged, the side end of the circular column 41 is against the second through hole 106 for sealing, so that the magnetic impurities in the slag discharge area 105 leak out of the shell through the second through hole 106, which is reliable to use; a clamping ring 107 is provided on the shell 1 to limit the sealing ring 5, and the sealing ring 5 is firmly installed and tightly sealed The seal is stable; the sealing ring 5 includes a first sealing ring 51 and a second sealing ring 52. There are two sealing rings, which have the effect of double sealing and improve the sealing performance. At the same time, it can perform a secondary scraping function on the magnetic impurities on the magnetic rod, and the slag discharge is cleaner and more thorough; the magnetic rod group 3 includes multiple magnetic rods 31 distributed in the horizontal direction, and one end of the magnetic rod 31 is connected to a connecting frame 32. The multiple magnetic rods 31 are connected by the connecting frame 32, so that the magnetic rods 31 of the same group of magnetic rod groups 3 slide synchronously; the magnetic rod group 3 is provided with multiple groups in the vertical direction. When removing iron, the driving component is used to slide one or more layers of magnetic rods that are less than the total number of layers out of the shell 1 to one side to complete the slag removal, and the remaining layers of magnetic rods that have not been pulled out continue to remove iron from the material, so that iron removal and slag discharge can be carried out simultaneously without stopping material feeding, which greatly improves the iron removal efficiency.

[0031] See Figure 1 、 Figure 2 、 Figure 3 and Figure 6The driving component includes a cylinder group 6, which is fixed on the shell 1. There are multiple groups of cylinder groups 6 in the vertical direction. The cylinder groups 6 correspond to the magnetic rod groups 3 one by one. The cylinder group 6 includes two parallel cylinders. The output rods of the cylinders are connected to the connecting frame 32. The side end of the shell 1 is connected with a dust cover 7 to prevent the magnetic impurities in the slag discharge area 105 from leaking to the outside through the second through hole, and to prevent external dust from falling on the magnetic rod. An opening 72 is provided at the bottom of the dust cover 7, and the switch of the opening 72 can be controlled by a manual valve to discharge impurities in the dust cover 7; a guide rod 71 extending in the horizontal direction is provided in the dust cover 7, and the guide rod 71 passes through the connecting frame 32. A guide sleeve 321 is fixedly provided on the connecting frame 32, and the guide sleeve 321 is slidably sleeved on the guide rod 71 to prevent the magnetic rod from tilting when sliding, so that the magnetic rod slides smoothly and smoothly.

[0032] The utility model discloses a double-sealed powder automatic drawer type iron remover. When removing magnets, it is not easy for the iron removal area and the slag discharge area to cross-contamination. The magnetic impurities on the magnetic rod are scraped away by the spacer sleeve, and the magnetization is more clean and thorough, with good use effect.

A sealing ring is provided on the shell body for sealing the second through hole, so that the magnetic impurities in the slag discharge area are prevented from leaking out of the shell body through the second through hole. It is reliable to use. At the same time, the sealing ring can also scrape the magnetic impurities on the magnetic rod again, making the slag discharge more thorough and improving the magnetization efficiency.
