Description

Technical Field

[0001] This invention relates to the field of iron removal technology, and in particular to a self-cleaning iron remover. Background Technology

[0002] Iron separators use their own magnetic force to adsorb magnetic substances mixed in the medium flowing through them, thereby achieving the purpose of iron removal. They are widely used in industries such as chemical engineering.

[0003] Currently, magnetic separators typically consist of a housing, a cover, and a magnetic rod fixed to the cover. The cover is connected to the housing, and the magnetic rod is located inside the housing. The magnetic rod will attract magnetic substances mixed in with powder or solution flowing through the housing. After a period of use, a thick layer of magnetic foreign matter will be adsorbed on the magnetic rod. At this time, the cover needs to be removed, and the magnetic foreign matter on the magnetic rod can be scraped off using a ring or other structure. The cleaned magnetic rod can then be reused.

[0004] However, due to the large number of magnetic rods and the weight of the box lid and magnetic rods, it is necessary to use a machine to lift the box lid, making cleaning extremely inconvenient, time-consuming, and labor-intensive. Summary of the Invention

[0005] In view of this, it is necessary to provide a self-cleaning magnetic separator to solve the problem that the cleaning process of magnetic rods is extremely inconvenient, time-consuming and labor-intensive.

[0006] This invention provides a self-cleaning iron remover, comprising an iron removal box, a magnetic suction assembly, an enclosure assembly, a slag scraping ring, and a drive assembly. The iron removal box has an inlet and an outlet. The iron remover also includes a slag discharge pipe communicating with the interior of the iron removal box and a valve installed on the slag discharge pipe. The magnetic suction assembly includes a magnetic rod, which is fixedly connected to the inner wall of the iron removal box and positioned close to the slag discharge pipe. The enclosure assembly includes a cover and a pusher. The cover is slidably and sealingly connected to the iron removal box along the length of the magnetic rod. The cover slides to a position offset from the magnetic rod, or slides until its opening is tightly against the inner wall of the iron removal box to form a cleaning chamber for enclosing the magnetic rod. The cleaning chamber can communicate with the slag discharge pipe. The inner wall of the slag scraping ring slidably abuts against the outer wall of the magnetic rod. The drive assembly is installed on the iron removal box, and its output end is connected to the slag scraping ring to drive the slag scraping ring to scrape off the magnetic material on the side wall of the magnetic rod.

[0007] Furthermore, the feed inlet and the discharge outlet are arranged sequentially in the horizontal direction, and the number of magnetic rods is multiple and arranged vertically.

[0008] Furthermore, the number of the cover is one, and the cleaning cavity formed between the cover and the iron removal box is used to enclose multiple magnetic rods.

[0009] Furthermore, there are multiple covers, and the cleaning chamber formed between the cover and the iron removal box is used to enclose at least one of the magnetic rods.

[0010] Furthermore, the magnetic attraction assembly also includes a sliding rod, a float, and a pressure sensor. The sliding rod is vertically arranged, and its bottom end is fixedly connected to the inner bottom wall of the iron removal box. The float is cylindrical and sleeved on the sliding rod, and the float is slidably connected to the sliding rod. The magnetic rod is cylindrical and sleeved on the float, and the magnetic rod is fixedly connected to the float. The pressure sensor is fixedly arranged on the inner bottom wall of the iron removal box and is vertically aligned with the magnetic rod. When a large amount of magnetic material is adsorbed on the magnetic rod, the magnetic rod sinks to a position that contacts the sensing end of the pressure sensor, which can control the action of the pusher and the drive assembly.

[0011] Furthermore, a lock head is fixedly connected to the top of the slide rod, and the outer diameter of the lock head is larger than the outer diameter of the slag scraper ring, so as to limit the upward floating position of the magnetic rod and the slag scraper ring.

[0012] Furthermore, the outer wall of the slag scraper ring slides and seals against the inner wall of the cover, and the inner wall of the slag scraper ring slides and seals against the outer wall of the magnetic rod.

[0013] Furthermore, an annular scraper is fixedly connected to one side of the slag scraper ring, and the annular scraper slides against the inner wall of the magnetic rod.

[0014] Furthermore, the drive assembly includes a water pump, a main pipe, and a water injection connector. The water pump is installed on the top of the iron removal box. The water pump is connected to the water injection connector via the main pipe. The water injection connector is connected to the cavity of the scraper ring in the cover away from the opening. Water is injected into and pumped out of the cover to drive the scraper ring.

[0015] Furthermore, a limiting block is fixedly connected to the inner wall of the opening of the cover, and the cover drives the limiting block to move synchronously to drive the scraper ring to reset.

[0016] Compared with existing technologies, the powder or solution to be removed from the iron flows into the iron removal box through the feed inlet and flows out through the discharge outlet. During the above process, the magnetic rod can adsorb the magnetic substances mixed in the powder or solution. After running for a period of time, a lot of magnetic substances are adsorbed on the magnetic rod, and the iron removal efficiency decreases. The magnetic rod needs to be cleaned. The cleaning process is as follows: the cover is moved by the pusher, and the cover and the iron removal box form a cleaning chamber. At this time, the magnetic rod is located in the cleaning chamber. The scraper ring is moved by the drive, which can scrape off the magnetic substances on the magnetic rod. The valve is opened and discharged through the slag outlet pipe. After cleaning, the cover slides to a position that is offset from the magnetic rod, and the magnetic rod is put back into use.

Detailed Implementation

[0018] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0019] like Figure 1-3 As shown, the present invention provides a self-cleaning iron separator, comprising an iron removal box 100, a magnetic suction assembly 200, an enclosure assembly 300, a slag scraping ring 400, and a drive assembly 500. The iron removal box 100 has an inlet and an outlet. The iron separator also includes a slag discharge pipe 110 communicating with the interior of the iron removal box 100 and a valve 120 installed on the slag discharge pipe 110. The magnetic suction assembly 200 includes a magnetic rod 210, which is fixedly connected to the inner wall of the iron removal box 100 and disposed close to the slag discharge pipe 110. The enclosure assembly 300 includes a cover 310 and a pusher 320. The cover 310 and the iron removal box 100 slide and are sealed together along the length of the magnetic rod 210. The cover 310 slides to a position offset from the magnetic rod 210, or slides to a position where its opening is close to the inner wall of the iron removal box 100 to form a cleaning chamber for enclosing the magnetic rod 210. The cleaning chamber can be connected to the slag discharge pipe 110. The inner wall of the scraper ring 400 slides against the outer wall of the magnetic rod 210. The drive assembly 500 is installed on the iron removal box 100 and its output end is connected to the scraper ring 400 to drive the scraper ring 400 to slide and scrape off the magnetic material on the side wall of the magnetic rod 210.

[0020] During implementation, the powder or solution to be removed from the iron flows into the iron removal box 100 through the feed inlet and flows out through the discharge outlet. During the above process, the magnetic rod 210 can adsorb the magnetic substances mixed in the powder or solution. After running for a period of time, a lot of magnetic substances are adsorbed on the magnetic rod 210, the iron removal efficiency decreases, and the magnetic rod 210 needs to be cleaned.

[0021] The cleaning process is as follows: The pusher 320 drives the cover 310 to move, and the cover 310 and the iron removal box 100 form a cleaning chamber. At this time, the magnetic rod 210 is located in the cleaning chamber. The drive unit drives the scraper ring 400 to move, which can scrape off the magnetic material on the magnetic rod 210. The valve 120 is opened and discharged through the slag outlet pipe 110. After cleaning, the cover 310 slides to a position that is offset from the magnetic rod 210, and the magnetic rod 210 is put back into use.

[0022] The iron removal box 100 in this embodiment has a feed inlet and a discharge outlet. The iron remover also includes a slag discharge pipe 110 that connects to the inside of the iron removal box 100 and a valve 120 installed on the slag discharge pipe 110.

[0023] The feed inlet and discharge outlet are arranged in sequence along the horizontal direction, and the number of magnetic rods 210 is multiple and arranged vertically.

[0024] The magnetic suction assembly 200 in this embodiment includes a magnetic rod 210, which is fixedly connected to the inner wall of the iron removal box 100 and is located near the slag discharge pipe 110.

[0025] To facilitate the monitoring of magnetic foreign matter accumulation on the magnetic rod 210, in one embodiment, the magnetic attraction assembly 200 further includes a slide rod 220, a float 230, and a pressure sensor 240. The slide rod 220 is vertically arranged, and its bottom end is fixedly connected to the inner bottom wall of the iron removal box 100. The float 230 is cylindrical and sleeved on the slide rod 220, and the float 230 is slidably connected to the slide rod 220. The magnetic rod 210 is cylindrical and sleeved on the float 230, and the magnetic rod 210 is fixedly connected to the float 230. The pressure sensor 240 is fixedly arranged on the inner bottom wall of the iron removal box 100 and is vertically aligned with the magnetic rod 210. When a large amount of magnetic material is adsorbed on the magnetic rod 210, the magnetic rod 210 sinks to a position where it contacts the sensing end of the pressure sensor 240, which controls the action of the pusher 320 and the drive assembly 500.

[0026] It is understood that the float 230 can be made of a lighter material. When the magnetic rod 210 does not adsorb magnetic material or adsorbs less magnetic material, the buoyancy added by the float 230 to the magnetic rod 210 can make the bottom of the magnetic rod 210 and the pressure sensor 240 set at an interval.

[0027] The pressure sensor 240 can be implemented using a contact switch or similar structure. It is connected to the valve 120, the pusher 320, and the drive assembly 500. When the pressure sensor 240 detects the pressure applied to it by the magnetic rod 210, it can control the valve 120 to open, and the pusher 320 and the drive assembly 500 to act synchronously or with a delay.

[0028] A lock head 221 is fixedly connected to the top of the slide bar 220. The outer diameter of the lock head 221 is larger than the outer diameter of the scraper ring 400, which is used to limit the upward position of the magnetic rod 210 and the scraper ring 400.

[0029] The enclosure component 300 in this embodiment includes a cover 310 and a pusher 320. The cover 310 and the iron removal box 100 are slidably and sealed together along the length of the magnetic rod 210. The cover 310 is slid to a position offset from the magnetic rod 210 or slid to a position where its opening is close to the inner wall of the iron removal box 100 to form a cleaning chamber for enclosing the magnetic rod 210. The cleaning chamber can be connected to the slag discharge pipe 110.

[0030] The pusher 320 can be implemented using a pusher cylinder. Both the inner and outer walls of the scraper ring 400 are connected to sealing rings. To prevent wear on the sealing rings, in one embodiment, an annular scraper 410 is fixedly connected to one side of the scraper ring 400, and the annular scraper 410 slides against the inner wall of the magnetic rod 210. When the bottom of the cover 310 is open, the annular scraper 410 is positioned at the bottom of the scraper ring 400.

[0031] In one embodiment, there is one cover 310, and the cleaning chamber formed between the cover 310 and the iron removal box 100 is used to enclose multiple magnetic rods 210. There are multiple corresponding scraper rings 400, and the multiple scraper rings 400 are connected to slide synchronously.

[0032] like Figure 4 As shown, in another embodiment, there are multiple covers 310, and the cleaning cavity formed between the cover 310 and the iron removal box 100 is used to enclose at least one magnetic rod 210. At the same time, the pusher 320 can be connected to the top of the multiple covers 310 through a connecting plate 330.

[0033] In this embodiment, the outer wall of the scraper ring 400 slides and seals against the inner wall of the cover 310, and the inner wall of the scraper ring 400 slides and seals against the outer wall of the magnetic rod 210.

[0034] In this embodiment, the drive component 500 is a structure that drives the scraper ring 400 to move.

[0035] In one embodiment, the drive assembly 500 includes a water pump 510, a main pipe 520, and a water injection connector 530. The water pump 510 is mounted on the top of the iron removal box 100. The water pump 510 is connected to the water injection connector 530 via the main pipe 520. The water injection connector 530 is connected to the cavity of the scraper ring 400 in the cover 310 away from the opening. Water is injected into and pumped out of the cover 310 to drive the scraper ring 400 to move.

[0036] like Figure 2As shown, in one embodiment, a limiting block 311 is fixedly connected to the inner wall of the opening of the cover 310. The cover 310 drives the limiting block 311 to move synchronously to drive the scraper ring 400 to reset. The limiting block 311 abuts against the bottom of the scraper ring 400. When the cover 310 moves upward, it can drive the scraper ring 400 to move upward synchronously.

[0037] Understandably, the drive assembly 500 can also be implemented using structures such as telescopic cylinders.

[0038] Compared with existing technologies: The powder or solution to be removed from iron flows into the iron removal box 100 through the feed inlet and flows out through the discharge outlet. During the above process, the magnetic rod 210 can adsorb the magnetic substances mixed in the powder or solution. After running for a period of time, a lot of magnetic substances are adsorbed on the magnetic rod 210, and the iron removal efficiency decreases. The magnetic rod 210 needs to be cleaned. The cleaning process is as follows: The pusher 320 drives the cover 310 to move. The cover 310 and the iron removal box 100 form a cleaning chamber. At this time, the magnetic rod 210 is located in the cleaning chamber. The drive unit drives the scraper ring 400 to move, which can scrape off the magnetic substances on the magnetic rod 210. The valve 120 is opened and discharged through the slag discharge pipe 110. After cleaning, the cover 310 slides to a position that is offset from the magnetic rod 210, and the magnetic rod 210 is put back into use.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
