Description

Technical Field

[0001] This utility model relates to the field of magnetic device technology, and in particular to a magnetic drawer-type iron separator. Background Technology

[0002] In soda ash production, the impurity that significantly affects the quality of the finished soda ash product is "iron foreign matter," mainly consisting of iron fragments and pieces. The main components of this "iron foreign matter" are iron fragments and pieces from the scraper chain fins and other soda ash conveying equipment. The scraper chain fins, subjected to long-term corrosion from soda ash and immense tensile force, experience metal fatigue deformation and eventually breakage, producing magnetic fragments and pieces such as iron filings and magnetite. Magnetic drawer-type iron separators have long been used in the removal of iron foreign matter in soda ash conveying lines. For example, patent CN218394101U discloses a magnetic particle adsorption and removal device. In this magnetic drawer-type iron separator, a strong magnetic rod is placed in a sleeve welded integrally with the magnetic drawer. However, the lifespan of magnetic drawers is generally short. Once the magnetic drawer is subjected to a strong impact from soda ash blocks or iron foreign matter, causing the sleeve to deform, the strong magnetic rod cannot be pulled out of the magnetic drawer to remove the iron foreign matter, rendering the entire magnetic drawer unusable. This necessitates the expenditure of significant funds to purchase a new one, resulting in a substantial increase in production costs. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a magnetic drawer-type iron separator, which has the characteristics of high strength, high magnetic permeability and high ability to block foreign objects.

[0004] To achieve this technical objective, the present invention adopts the following solution: A magnetic drawer-type iron separator includes an outer frame, a sleeve, and a magnetic rod. The outer frame is a rectangular structure composed of an outer frame top plate, an outer frame bottom plate, and two side plates. The two ends of the two side plates are fixedly connected to the outer frame top plate and the outer frame bottom plate, respectively. The sleeve is set inside the outer frame, and the magnetic rod is set inside the sleeve. A circular opening is provided on the outer frame top plate, and a bottom plate sleeve is provided on the outer frame bottom plate. The number and position of the bottom plate sleeves correspond to the circular openings on the outer frame top plate. The sleeve passes through the circular openings and is installed inside the bottom plate sleeves.

[0005] Furthermore, a tie plate is provided inside the outer frame, with both ends of the tie plate being fixedly connected to two side plates respectively, and the tie plate having round holes corresponding to the round openings on the top plate of the outer frame.

[0006] Furthermore, the two ends of the sleeve and the parts that mate with the tie rod partition are thickened.

[0007] Furthermore, handles are fixedly connected to both ends of the top plate of the outer frame away from the bottom plate of the outer frame, and the two handles are symmetrically arranged.

[0008] Furthermore, the end of the sleeve away from the top plate of the outer frame is a closed structure, and the end of the sleeve near the top plate of the outer frame is provided with a sleeve top plate. The upper and lower sides of the circular opening on the top plate of the outer frame are provided with sleeve guide wires. The sleeve guide wires pass through the sleeve top plate and are fixed with nuts. An asbestos gasket is provided between the sleeve top plate and the top plate of the outer frame.

[0009] Furthermore, a magnetic rod top plate is provided at one end of the magnetic rod near the top plate of the outer frame. Magnetic rod wires are provided on the left and right sides of the circular opening on the top plate of the outer frame. The magnetic rod is inserted into the sleeve, and the magnetic rod wires pass through the top plate of the sleeve and the magnetic rod top plate and are fixed with nuts.

[0010] Furthermore, the depth of the sleeve is greater than the length of the magnetic rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The removable sleeve structure allows for the replacement of individual magnetic rods and sleeves, thereby extending the service life of the iron separator and reducing its maintenance costs.

[0012] 2. The magnetic rod sleeve adopts a non-uniform wall thickness design. The two ends of the sleeve and the parts that cooperate with the tie rod partition are thickened, which increases the strength and enhances the impact resistance of the sleeve, thus avoiding the situation where the magnetic rod cannot be pulled out due to deformation and the entire magnetic drawer is scrapped.

[0013] 3. The addition of tie rods and partitions strengthens the overall structure of the magnetic drawer, provides support for the magnetic rod sleeve, reduces the probability of the magnetic rod sleeve being deformed by impact, and the horizontal placement of the tie rods and partitions plays a certain role in breaking up the alkali blocks, reducing the possibility of alkali blockage during transport.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0017] Please see Figure 1This utility model provides a magnetic drawer-type iron remover, including an outer frame, a sleeve 8, and a magnetic rod 5. The sleeve 8 is disposed inside the outer frame, and the magnetic rod 5 is disposed inside the sleeve 8. The outer frame is a rectangular structure composed of an outer frame top plate 12, an outer frame bottom plate 13, and two side plates 1. The two ends of the two side plates 1 are fixedly connected to the outer frame top plate 12 and the outer frame bottom plate 13, respectively. Handles 3 are fixedly connected to the two ends of the outer frame top plate 12 away from the outer frame bottom plate 13. The two handles 3 are symmetrically arranged, allowing the device to be manually pulled out or moved through the handles 3.

[0018] The top plate 12 of the outer frame has a circular opening, and the bottom plate 13 of the outer frame has a bottom plate sleeve 11. The number of bottom plate sleeves 11 is the same as the number of circular openings on the top plate 12 of the outer frame, and the positions of the bottom plate sleeves 11 correspond to the positions of the circular openings. The sleeve 8 has a sleeve top plate 7 at one end near the top plate 12 of the outer frame, and the other end of the sleeve 8 is a closed structure. The sleeve 8 passes through the circular opening and is installed inside the bottom plate sleeve 11.

[0019] Four pairs of sleeve guide wires 9 are provided on the upper and lower sides of the circular opening on the top plate 12 of the outer frame. The sleeve guide wires 9 pass through the top plate 7 of the sleeve and are fixed with nuts. An asbestos pad 4 is provided between the top plate 7 of the sleeve and the top plate 12 of the outer frame to prevent smoke and dust from leaking out.

[0020] Four pairs of magnetic rod wires 6 are provided on the left and right sides of the circular opening on the top plate 12 of the outer frame. A magnetic rod top plate 10 is provided at one end of the magnetic rod 5 near the top plate 12 of the outer frame. The other end of the magnetic rod 5 is inserted into the sleeve 8. The magnetic rod wires 6 pass through the top plate 7 of the sleeve and the top plate 10 of the magnetic rod and are fixed with nuts.

[0021] The magnetic rod 5 is a strong magnetic rod with a magnetic field strength of 12000GS. The magnetic rod 5 is installed inside the sleeve 8, and the pull rod of the magnetic rod 5 extends out of the sleeve 8. The depth of the sleeve 8 is greater than the length of the magnetic rod 5.

[0022] A tie-bar partition 2 is installed inside the outer frame. Both ends of the tie-bar partition 2 are fixedly connected to two side plates 1, respectively, to increase the mechanical strength of the magnetic drawer-type iron separator and provide support for the sleeve 8, reducing the probability of the sleeve 8 being deformed by impact. The horizontal placement of the tie-bar partition 2 also helps to break up the alkali blocks, reducing the possibility of alkali transport blockage. The tie-bar partition 2 has circular holes corresponding to the circular openings on the top plate 12 of the outer frame.

[0023] In this embodiment, two tie rod partitions 2 are provided inside the outer frame, respectively located at 1 / 3 and 2 / 3 of the two side plates 1.

[0024] The sleeve 8 adopts a non-uniform wall thickness design. The two ends of the sleeve 8 and the parts that cooperate with the tie plate 2 are thickened, which makes it stronger and enhances the impact resistance of the sleeve 8, thus avoiding the situation where the magnetic rod 5 cannot be pulled out due to deformation and the entire magnetic drawer is scrapped.

[0025] In this embodiment, the sleeve 8 is made of 316L stainless steel pipe with a wall thickness of 3mm. The two ends of the sleeve 8 and the parts that cooperate with the tie plate 2 are thickened with a wall thickness of 3mm and a length of 10mm. The other parts of the sleeve 8 are thinned, with the wall thickness as thin as 0.35mm, so that the magnetic flux is higher and the ability to attract iron foreign objects is stronger.

[0026] The operation of this magnetic drawer-type iron separator is as follows: the top plate 12, bottom plate 13, side plate 1, tie rod partition 2, and sleeve 8 are all made of 316L stainless steel and connected by welding. The assembled magnetic drawer-type iron separator is horizontally installed in the pre-reserved installation slot in the equipment, which is equal in length and width to the alkali transport channel. Soda ash flows to the next process through the gaps between the side plate 1, tie rod partition 2, and sleeve 8, while ferrous foreign objects are adsorbed onto the sleeve 8 of the magnetic drawer-type iron separator.

[0027] Operators change shifts every 8 hours. Each shift requires cleaning the magnetic drawer-type iron separator. Loosen the fixing nuts on both sides of the top plate 12 of the outer frame, pull the handle 3, and pull the magnetic drawer-type iron separator out of the mounting slot. After loosening the nut on the magnetic rod wire 6 on the top plate 12 of the outer frame, pull the magnetic rod 5 out of the sleeve 8. The iron foreign matter adsorbed on the sleeve 8 can then be cleaned. The sleeve 8 of this device adopts a non-uniform wall thickness design. The parts that have a clearance fit with the tie plate 2, the top plate 12 of the outer frame, and the bottom plate outer sleeve 11 use a thickened structure with a wall thickness of 3mm and a length of 10mm. This enhances the strength of the sleeve 8 and also increases the magnetic flux of the magnetic rod 5, making it superior to similar magnetic drawer-type iron separators. All magnetic drawer-type iron separators of the same type use welding to integrate the sleeve 8 with the top plate 12 and the bottom plate 13 of the outer frame. Even if a single sleeve 8 is damaged, the entire device must be replaced. This device adopts a detachable sleeve 8 design, and a single damaged sleeve 8 can be replaced individually, which greatly reduces the cost of use and also greatly extends the service life of the device.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. If these modifications and variations fall within the scope of the claims of this utility model and their equivalents, they should be considered to be within the protection scope of this utility model.
