Description

Technical Field

[0001] This utility model relates to the field of impurity removal technology, and in particular to a dual-port automatic cleaning drawer magnetic separator. Background Technology

[0002] In the processing of powders and granules in the food, pharmaceutical, and chemical industries, raw materials or semi-finished products often contain ferromagnetic impurities (such as metal fragments). To eliminate the hazards of such impurities to product quality and equipment safety, pipeline magnetic separators are widely used in material conveying processes. Traditional magnetic separators typically employ the following structural design: a permanent magnet array is fixedly installed inside the pipeline. When material flows through, ferromagnetic impurities are adsorbed onto the surface of the magnetic rods. After a period of use, when it is necessary to clean the impurities adsorbed on the magnetic rods, the machine must be stopped, the pipeline disassembled, or the magnetic rods removed, the adsorbed impurities manually scraped off, and then the magnetic rods reinstalled for continued use.

[0003] However, this traditional magnetic separator has the following drawbacks in actual use: 1. Low cleaning efficiency and time-consuming and labor-intensive cleaning operation. The magnetic separator lacks a quick opening and closing structure. During cleaning, the machine must be completely stopped and the parts must be disassembled for cleaning, resulting in long production line interruption time and high manual operation intensity. 2. Insufficient adsorption range. The magnetic rod is statically fixed in a single pipe, and the magnetic field area is limited. For materials with large flow or high flow rate, impurities are prone to escape, and the impurity removal rate is difficult to improve. Utility Model Content

[0004] In view of the above situation and in order to make up for the shortcomings of the existing technology, the purpose of this utility model is to provide a dual-port automatic cleaning drawer magnetic separator, which effectively solves the problems of time-consuming and laborious cleaning and insufficient adsorption range of existing magnetic separators.

[0005] The technical solution is as follows: This utility model includes a main shell, with feed pipes on the front and rear sides of the upper end of the main shell, and discharge cylinders located below the feed pipes on the front and rear sides of the lower end of the main shell. An impurity cylinder is located to the right of the discharge cylinder at the lower end of the main shell. Sliding columns with left and right axial orientations are provided at the front and rear ends of the main shell. A fixed plate located inside the main shell is slidably connected to the sliding column. Multiple parallel fixed cylinders with left and right axial orientations are provided at the right end of the fixed plate. An adsorption sleeve is coaxially provided inside the fixed cylinder. A magnetic rod is slidably connected to the adsorption sleeve. A movable plate located to the right of the fixed plate and capable of moving left and right is slidably connected to the sliding column. The right end of the magnetic rod extends out of the adsorption sleeve and is fixedly connected to the movable plate. A magnetic ring is coaxially provided at the right end of the fixed plate.

[0006] Preferably, the main body shell is provided with cylinders at both the front and rear ends, respectively, located below the sliding column, and the cylinder output shaft is fixedly connected to the moving plate.

[0007] Preferably, the main body shell is provided with reinforcing beams at both the front and rear ends, and a limiting plate located to the right of the fixing plate and in contact with the fixing plate is provided between the two reinforcing beams.

[0008] Preferably, the plurality of adsorption sleeves are fixedly connected by a reinforcing plate.

[0009] Preferably, the fixed plate and the movable plate are connected to the sliding column via linear bearings.

[0010] Preferably, the rear end of the main body shell is provided with a solenoid valve, which is electrically connected to the cylinder.

[0011] Preferably, the reinforced beam is equipped with a protective plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: it can fully adsorb, remove and collect iron filings and foreign objects in materials.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the implementations of the base model disclosed below.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Depend on Figures 1 to 6 The device includes a main shell 1, with feed pipes 2 on the front and rear sides of the upper end of the main shell 1, and discharge cylinders 3 located below the feed pipes 2 on the front and rear sides of the lower end of the main shell 1. An impurity cylinder 4 is located to the right of the discharge cylinder 3 at the lower end of the main shell 1. Sliding columns 5 are provided on the front and rear ends of the main shell 1, with a fixed plate 6 slidably connected to the sliding column 5 inside the main shell 1. Multiple parallel fixed cylinders 7 are provided on the right end of the fixed plate 6, with an adsorption sleeve 8 coaxially provided inside the fixed cylinder 7. A magnetic rod 9 is slidably connected to the adsorption sleeve 8, and a movable plate 10 located to the right of the fixed plate 6 and movable to the left and right is slidably connected to the sliding column 5. The right end of the magnetic rod 9 extends out of the adsorption sleeve 8 and is fixedly connected to the movable plate 10. A magnetic ring 11 is coaxially provided on the right end of the fixed plate 6.

[0025] In order to enable the movable plate 10 to move left and right, the main body shell 1 is provided with cylinders 12 located below the sliding column 5 at both the front and rear ends, and the output shaft of the cylinder 12 is fixedly connected to the movable plate 10.

[0026] To facilitate the positioning of the fixing plate 6, the main body shell 1 is provided with reinforcing beams 13 at both the front and rear ends, and a positioning plate 14 located to the right of the fixing plate 6 and in contact with the fixing plate 6 is provided between the two reinforcing beams 13.

[0027] To prevent the adsorption sleeves 8 from tilting, the multiple adsorption sleeves 8 are fixedly connected by a reinforcing plate 15.

[0028] To facilitate the sliding of the fixed plate 6 and the movable plate 10, the fixed plate 6 and the movable plate 10 are connected to the sliding column 5 via a linear bearing 16.

[0029] To facilitate the control of the cylinder 12 opening, a solenoid valve 17 is provided at the rear end of the main body shell 1, and the solenoid valve 17 is electrically connected to the cylinder 12.

[0030] For ease of protection, the reinforcing beam 13 is provided with a protective plate 18.

[0031] When this utility model is in use, the material is first injected simultaneously from the double feed pipes 2 on the front and rear sides of the upper end of the main body shell 1, and flows through the internal channel of the main body shell 1. At this time, the cylinder 12 is in a contracted state, and the magnetic rods 9 arranged in parallel in the fixed cylinder 7 adsorb the ferromagnetic impurities in the material onto the surface of the adsorption sleeve 8 through a strong magnetic field, thereby achieving the removal of impurities from the material. The purified material continues to flow downward and is discharged from the double discharge cylinders 3 on the front and rear sides of the lower end of the main body shell 1, thereby achieving continuous impurity removal.

[0032] When impurities need to be cleaned after a period of use, the solenoid valve 17 sends a command, and the cylinders 12 at both ends of the main body shell 1 move synchronously. Their output shafts push the moving plate 10 to move to the right, that is, towards the impurity cylinder 4. Since the right end of the magnetic rod 9 is fixed to the moving plate 10, and the adsorption sleeve 8 is constrained in the fixed cylinder 7 of the fixed plate 6, the magnetic rod 9 begins to slide out coaxially from the adsorption sleeve 8. At this time, the magnetic ring 11 fixed to the right end of the fixed plate 6 and the moving magnetic rod 9 generate a strong magnetic attraction force, which pulls the fixed plate 6, the adsorption sleeve 8 and the attached impurities to the right as a whole. After moving a distance to the right, it is blocked by the limiting plate 14 and stops at the position directly above the impurity cylinder 4.

[0033] As cylinder 12 continues to advance, moving plate 10 drives magnetic rod 9 to move further to the right. The axial distance between magnetic rod 9 and adsorption sleeve 8 continues to increase. According to the characteristic that magnetic field strength decreases with distance, the magnetic field effect on the surface of adsorption sleeve 8 weakens sharply. When the magnetic force weakens to the point that it is not enough to bind impurities, the iron filings automatically fall off the surface of the sleeve under the action of gravity and fall vertically into the impurity cylinder 4 below and flow out.

[0034] After cleaning, the solenoid valve 17 controls the cylinder 12 to retract, and the output shaft of the cylinder 12 pulls the moving plate 10 to the left to reset. The magnetic rod 9 then re-inserts to the left and is coaxially embedded in the adsorption sleeve 8, restoring the strong magnetic field state. At the same time, the attraction force of the magnetic ring 11 drives the fixing plate 6 and the adsorption sleeve 8 to slide to the left along the sliding column 5 until they are completely reset inside the working cavity of the main body shell 1, at which point they can be used again.

[0035] Compared with the prior art, the beneficial effects of this utility model are: the magnetic rod, adsorption sleeve, moving plate, and fixed plate can fully adsorb, remove and collect iron filings and foreign objects in the material. Due to the setting of the dual feed pipe, the working efficiency can be accelerated. At the same time, it can automatically clean the impurities adsorbed on the adsorption sleeve. Compared with the traditional manual cleaning, it is easy to operate and saves time and effort. This structure is simple, novel in concept, convenient to use and highly practical.

[0036] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
