Description

Technical Field

[0001] This utility model relates to the field of iron removal technology, and more specifically, to a fine-filtration type automatic slurry iron remover. Background Technology

[0002] With the continuous advancement of science and technology, slurry iron separators have been widely used in many industrial fields such as cement, glass, chemical, ceramics, and food. Their core working principle is: the slurry material flows through the separator equipped with magnetic rods, and the strong magnetic field generated by the magnetic rods adsorbs and removes iron powder or other powdery magnetic impurities mixed in the material, thereby ensuring the purity and quality of the final product.

[0003] In existing technologies, common slurry iron separators typically consist of a non-magnetic sleeve fitted over a magnetic rod. During operation, magnetic impurities are adsorbed onto the outer wall of the sleeve; during cleaning, the sleeve is removed from the magnetic rod, removing it from the magnetic field, and the adsorbed impurities automatically detach due to the loss of magnetism, thus achieving slag removal. However, this traditional structure reveals two significant technical drawbacks in practical applications: First, if the inevitable assembly gap between the magnetic rod and the sleeve is too large, the magnetic field will be severely attenuated when transmitted to the outer wall of the sleeve, greatly weakening the effective adsorption force on impurities and directly reducing the iron removal efficiency. Second, if this gap is excessively reduced to enhance the magnetic force, it is highly likely that the magnetic rod and the sleeve will experience rigid collisions or friction during equipment operation or disassembly, causing not only mechanical damage to both surfaces but also accelerating the wear of key components, seriously affecting the stability and service life of the entire equipment. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model provides a fine-filtration type automatic slurry iron remover, comprising a frame and a feeding tank disposed on the frame. The feeding tank contains a feeding chamber, and the feeding tank has an opening communicating with the feeding chamber. A pipe frame is disposed within the feeding tank, and a material passage communicating with the feeding chamber is provided on the pipe frame. A magnetic rod assembly and a driving component are disposed on the frame. The material passage is adapted to be movably inserted into the magnetic rod assembly. During iron removal, the driving component drives the magnetic rod assembly to insert into the material passage from the opening, feeding the material into the slurry. When the slurry to be removed is introduced into the cavity, magnetic impurities in the slurry are adsorbed onto the magnetic rod assembly as it flows through the material passage. During slag discharge, the slurry is stopped from being introduced, and the driving component drives the magnetic rod assembly to be pulled out of the material passage. The magnetic rod assembly then pulls the magnetic impurities away from the material passage through the opening. This invention eliminates the gap of traditional sleeves by directly inserting the magnetic rod assembly into the material passage, achieving lossless magnetic field and high-efficiency iron removal, resulting in finer filtration of magnetic impurities. At the same time, it avoids mechanical friction and damage between components, improving the stability and service life of the equipment.

Detailed Implementation

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0029] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0030] See Figures 1-11This utility model provides a fine-filtration type automatic slurry iron remover, including a frame 1 and a conveying tank 2 disposed on the frame 1. The conveying tank 2 has a conveying cavity 201 and an opening 202 communicating with the conveying cavity 201, located at the upper end of the conveying tank 2. A pipe rack 203 is disposed inside the conveying tank 2, and a material passage 204 communicating with the conveying cavity 201 is provided on the pipe rack 203. A magnetic rod assembly 3 and a driving component are disposed on the frame 1. The material passage 204 is adapted to be movably inserted into the magnetic rod assembly 3. During iron removal, the driving component drives the magnetic rod assembly 3 to insert into the material passage 204 through the opening 202. The material channel 204 feeds the slurry to be removed into the conveying chamber 201. As the slurry flows through the material channel 204, magnetic impurities in the slurry are adsorbed onto the magnetic rod assembly 3. During slag discharge, the feeding of the slurry is stopped, and the driving component drives the magnetic rod assembly 3 to be pulled away from the material channel 204. The magnetic rod assembly 3 carries the magnetic impurities away from the conveying chamber 201 from the opening 202. This invention eliminates the gap of the traditional sleeve by directly inserting the magnetic rod assembly into the material channel, achieving lossless magnetic field and high-efficiency iron removal. At the same time, it avoids mechanical friction and damage between components, improves the stability and service life of the equipment, and realizes automated and efficient operation.

[0031] Specifically, this fine-filtration automatic slurry iron remover controls the insertion or extraction of the magnetic rod assembly into or out of the material passage 204 inside the material conveying tank 2 through a drive component, fundamentally solving the problem of magnetic force attenuation or friction damage caused by the gap between the magnetic rod and the sleeve in traditional structures. During iron removal, the magnetic rod is placed directly in the flow channel, and iron is removed by bare magnetism (without a traditional sleeve on the outside of the magnetic rod). The magnetic field is lossless, and it has a strong adsorption force on iron impurities in the slurry, resulting in high iron removal efficiency. During slag discharge, the magnetic rod carries the adsorbed impurities out of the conveying chamber 201 as a whole, thereby achieving the purpose of iron removal from the slurry. In addition, by setting up the pipe frame 203, the material passage 204 is set on the pipe frame 203, which facilitates the slurry in the material passage 204 to be fully magnetically removed by the magnetic rod. The effect of preventing the escape of magnetic impurities during the iron removal process is good, the iron removal efficiency is high, and the magnetic impurity filtration is more refined. In this embodiment, the diameter of the material passage 204 is slightly larger than the diameter of the magnetic rod. During iron removal, the slurry flow channel in each material passage 204 is a concentric flow channel surrounding the magnetic rod.

[0032] See Figure 1 , Figure 4 , Figure 6 and Figure 8The magnetic rod assembly 3 includes a connecting plate 31 and magnetic rods 32. Multiple magnetic rods 32 are provided in a one-to-one correspondence with the material passage 204. One end of each magnetic rod 32 is connected to the connecting plate 31. The driving component includes a first telescopic cylinder 41. A lifting plate 5 connects the telescopic rod of the first telescopic cylinder 41 to the connecting plate 31. The first telescopic cylinder 41 serves as a power source, transmitting power synchronously and smoothly to the entire magnetic rod assembly 3 via the lifting plate 5. This allows all magnetic rods to precisely and synchronously insert into or withdraw from their corresponding material passages, automating the iron removal and slag discharge processes and improving efficiency.

[0033] See Figure 4 The first telescopic cylinder 41 is connected to a check valve 43. The check valve 43 locks the position of the cylinder, ensuring that the telescopic rod of the first telescopic cylinder 41 remains in a raised state when discharging slag. This avoids the problem of the telescopic rod descending due to excessive weight on the lifting plate 5 or other malfunctions, ensuring the stability of the equipment under abnormal working conditions, thereby ensuring the safety of the continuous production process and the safety of the equipment itself.

[0034] See Figure 1 , Figure 2 , Figure 4 and Figure 5 The frame 1 is equipped with a scraper assembly and a second telescopic cylinder 42. The second telescopic cylinder 42 is used to drive the scraper assembly to slide along the axial direction of the magnetic rod assembly 3. The telescopic rod of the second telescopic cylinder 42 is connected to the scraper assembly. The scraper assembly is equipped with a scraper sleeve 61, which is sleeved on the magnetic rod 32. The magnetic rod 32 includes a magnetic section 321 and a non-magnetic section 322. The magnetic section 321 is connected to the upper end of the non-magnetic section 322. The lower part of the non-magnetic section 322 is provided with an annular inclined surface 323. During slag discharge, When the first telescopic cylinder 41 and the second telescopic cylinder 42 rise synchronously, the scraper assembly moves down through the second telescopic cylinder 42, and the magnetic impurities on the magnetic section 321 are scraped to the non-magnetic section 322 through the scraper sleeve 61. When the magnetic impurities are scraped to the non-magnetic section 322, they lose their magnetic force and fall into the slag collection box 10 below, completing the automated slag discharge process. The annular inclined surface 323 facilitates the smooth falling of slag material along the annular inclined surface 323 under the action of gravity, effectively preventing slag material from accumulating or sticking at the bottom of the magnetic rod.

[0035] See Figures 4-7The scraper assembly includes a first plate 62 and a second plate 63 connected together. The telescopic rod of the second telescopic cylinder 42 is connected to the first plate 62. A flange 611 is provided on the scraper sleeve 61. An installation groove 64 for fixing the flange 611 is provided between the first plate 62 and the second plate 63. The scraper sleeve 61 is made of rubber or silicone. The first plate 62 and the second plate 63 are fixed together by bolts, which is convenient for disassembly and assembly. Since the scraper sleeve 61 is a vulnerable part that needs to be replaced regularly, the convenient disassembly and assembly of the first plate 62 and the second plate 63 improves the convenience of the scraper sleeve 61 and reduces the maintenance cost of the equipment. The first plate 62 and the second plate 63 are both made of 304 stainless steel, which is corrosion resistant, has high structural strength, and high reliability.

[0036] See Figure 4 , Figure 5 , Figure 9 and Figure 10 The upper part of the conveying barrel 2 is provided with a first fastening block 205, and the lifting plate 5 is provided with a fastening cover 7 and a swing cylinder 8 for driving the fastening cover 7 to rotate circumferentially. The fastening cover 7 is provided with a second fastening block 701 that is movably fastened to the first fastening block 205. The output end of the swing cylinder 8 is connected to the fastening cover 7, so that the swing cylinder 8 can drive the fastening cover 7 to rotate forward, so that the first fastening block 205 and the second fastening block 701 are fastened and locked. The fastening cover 7 can be driven in the reverse direction. Reverse rotation is used to disengage and unlock the first locking block 205 from the second locking block 701; a sealing ring 206 is provided at the upper end of the conveying barrel 2, which improves the sealing performance between the locking cover 7 and the upper end of the conveying barrel 2, preventing slurry leakage; the mechanical locking effectively resists internal pressure, preventing accidental opening of the equipment during operation, ensuring high safety; at the same time, it prevents slurry leakage from the interface during iron removal, improving reliability; a first guide slope 2 is provided at the lower part of the first locking block 205. 051 and the first chamfer 2052, the second fastening block 701 is provided with a second guide slope 7011 corresponding to the first guide slope 2051 and a second chamfer 7012 corresponding to the first chamfer 2052; during the forward rotation of the fastening cover, the first fastening block 205 and the second fastening block 701 are fastened together by the first chamfer 2052 and the second chamfer 7012, and the first guide slope 2051 and the second guide slope 7011 ensure that after the fastening is completed, a product is generated. A force is generated to press the first fastening block 205 and the second fastening block 701 together, thereby improving the sealing and stability of the fastening cover when it is fastened. The angle between the first guide slope 2051 and the horizontal plane is 1°-3°. In this embodiment, the angle between the first guide slope 2051 and the horizontal plane is 1°, and the angle of the second guide slope 7011 corresponds to that of the first guide slope 2051, so that the angle of the second guide slope 7011 and the first guide slope 2051 fit together when fastened.

[0037] See Figure 6 and Figure 8 The pipe rack 203 includes an upper support plate 2031, a lower support plate 2032, and a feed pipe 2033. The feed pipe 2033 is connected between the upper support plate 2031 and the lower support plate 2032. The upper support plate 2031 and the lower support plate 2032 are both welded to the inner wall of the conveying chamber 201, so that the slurry in the conveying chamber 201 will definitely pass through the feed pipe 2033 for iron removal and to prevent the slurry from escaping without iron removal. Multiple feed pipes 2033 are provided, and the feed channel 204 is provided inside the feed pipe 2033.

[0038] See Figure 1 Multiple conveying barrels 2 are distributed horizontally, and a conveying pipe 9 connects two adjacent conveying barrels 2. The first and last conveying barrels 2 are respectively equipped with an inlet pipe 21 and an outlet pipe 22, and the positions of the inlet pipe 21 and the outlet pipe 22 can be interchanged; thus realizing the function of multi-stage series iron removal. The slurry flows in from the inlet pipe and flows through all the conveying barrels in series in sequence. Each barrel is an iron removal process, which can gradually and thoroughly adsorb the magnetic impurities that were not completely removed in the previous process, improve the overall iron removal efficiency, and achieve the purpose of fine filtration.

[0039] See Figure 1 and Figure 11 The fine-filtration automatic slurry iron remover also includes a slag collection box 10, which is placed on the upper end of the conveying barrel 2 to collect slag during slag discharge. A guide plate 11 is provided on the outer wall of the conveying barrel 2, and a collection box 12 is placed on the frame 1. The guide plate 11 is inclined to guide the slurry in the guide plate 11 to the collection box 12. The slag collection box 10 is used to collect magnetic slag scraped off from the magnetic rod, realizing fixed-point collection of waste. The inclined guide plate 11 and collection box 12 are used to collect and recover clean slurry dripped from the equipment, avoiding slurry waste and ensuring the cleanliness of the working area, thus improving the environmental friendliness and economy of the equipment.

[0040] See Figure 11 The frame 1 is also equipped with a control box 13, which can be equipped with buttons or an operation screen to manually control the iron removal time of the iron separator. That is, after the slurry is introduced for a certain time, the iron removal process can be started manually by pressing the button or the screen. The time can also be preset, and the iron removal process will be carried out automatically after the preset time is reached. Of course, the iron separator can also be controlled online through the control program of external equipment.

[0041] The working steps of this fine-filtration automatic slurry iron remover are as follows: First, the first telescopic cylinder 41 and the second telescopic cylinder 42 descend synchronously, driving the lifting plate 5, scraper assembly, fastening cover 7, and swing cylinder 8 to move down synchronously, so that the fastening cover 7 closes with the upper end of the conveying barrel 2. Then, the swing cylinder 8 drives the fastening cover 7 to rotate clockwise, so that the fastening cover 7 is tightly sealed with the upper part of the conveying barrel 2. Next, the slurry to be removed is introduced into the feed pipe 21, and the magnetic rod in the flow channel adsorbs the magnetic impurities in the slurry to be removed. After adsorption for a certain period of time, the introduction of the slurry to be removed is stopped, and the swing cylinder 8 drives the fastening cover 7 to rotate in the opposite direction, so that the fastening cover 7 is unlocked from the upper part of the conveying barrel 2. The first telescopic cylinder 41 and the second telescopic cylinder 42 rise synchronously, driving the lifting plate 5, scraper assembly, fastening cover 7, and swing cylinder 8 to move up synchronously. After moving up to the preset height, By opening the check valve to maintain the above components at a preset height, the slag collection box 10 is placed on the upper end of the conveying barrel 2. The second telescopic cylinder 42 drives the scraper assembly to scrape down the magnetic impurities on the magnetic rod, so that the magnetic impurities fall into the slag collection box 10. After the slag collection (slag discharge) is completed, the slag collection box 10 is removed, the check valve is closed, and the first telescopic cylinder 41 and the second telescopic cylinder 42 are lowered synchronously to drive the lifting plate 5, scraper assembly, fastening cover 7, and swing cylinder 8 to move down synchronously, so that the fastening cover 7 is closed with the upper end of the conveying barrel 2. Then, the swing cylinder 8 drives the fastening cover 7 to rotate in the forward direction, so that the fastening cover 7 is tightly sealed with the upper part of the conveying barrel 2. Then, the slurry to be removed is continued to be introduced into the feed pipe 21 to continue the iron removal process. After a certain period of iron removal, the slag discharge process is carried out. The above steps are repeated to achieve the purpose of iron removal.

[0042] The fine-filtration automatic slurry iron remover of this utility model eliminates the gap of traditional sleeves by directly inserting the magnetic rod assembly into the material passage, achieving lossless magnetic field and high-efficiency iron removal; at the same time, it avoids mechanical friction and damage between components, improves equipment stability and service life, and realizes automated and efficient operation; setting the material passage on the pipe rack facilitates the slurry in the material passage to be fully magnetically removed by the magnetic rod, effectively preventing the escape of magnetic impurities during the iron removal process, resulting in high iron removal efficiency and finer filtration of magnetic impurities.
