Description

Technical Field

[0001] The present application relates to the technical field of slurry magnetic impurity removal, and in particular to a novel slurry iron removal device. Background Art

[0002] At present, there are many styles of slurry iron removers on the market, mainly electromagnetic iron removers, flange-type permanent magnetic iron removers, and single-body permanent magnetic iron removers. Each type of slurry iron remover has its own advantages and disadvantages.

[0003] Among them, a single-body permanent magnetic iron remover is taken as an example for explanation. The single-body permanent magnetic iron remover adopts a narrow gap design, which includes a slurry tank body, a slurry flow pipeline is arranged in the slurry tank body, a detachable cover is sealed and connected to the slurry tank body, a magnetic rod is arranged in the slurry flow pipeline, the top end of the magnetic rod is fixed to the cover, and a narrow gap for the slurry to flow is formed between the magnetic rod and the slurry flow pipeline. When the slurry flows in the narrow gap, the magnetic rod can absorb the magnetic impurities (such as iron) of the slurry in the narrow gap. After a period of time, the staff removes the cover and the magnetic rod from the slurry tank body together, and removes the magnetic impurities on the surface of the magnetic rod. Although this method has high iron removal efficiency, it has the problems of small flow rate and difficulty in cleaning magnetic impurities.

[0004] Therefore, in order to improve production efficiency, many improved versions of iron removal equipment have appeared on the market. Generally, multiple slurry tanks connected in sequence are set up, and the principles of fluid mechanics are used to make the slurry pass through multiple slurry tanks in sequence to remove magnetic impurities in the slurry layer by layer, and the impurity removal effect is better.

[0005] For example, a Chinese patent with announcement number CN115228606B discloses a slurry impurity removal device and a slurry impurity removal method, wherein the slurry impurity removal device is connected in series to the slurry main pipeline, including a frame, a slurry tank body, a cover closing mechanism, a lifting mechanism and a power supply box, a plurality of slurry tank bodies are arranged side by side along the length direction of the frame, two adjacent slurry tank bodies are connected by a connecting pipe, the cover closing mechanism is arranged on the top of the plurality of slurry tank bodies, the lifting mechanism is arranged between the frame and the cover closing mechanism to push the cover closing mechanism close to or away from the slurry tank body, and the power supply box provides power for the slurry impurity removal device. This application arranges a plurality of slurry tank bodies connected in sequence, and utilizes the principle of fluid mechanics to make the slurry pass through the plurality of slurry tank bodies in sequence to remove the magnetic impurities in the slurry layer by layer, so as to achieve good impurity removal effect and high impurity removal efficiency.

[0006] However, the structural design of the device is relatively complex, especially the cover closing mechanism, which includes a support plate, a sealing cover, a rotating cover, a rotating seat, and a cover closing drive. The sealing cover, the rotating cover, the rotating seat and the cover closing drive are provided in multiple groups corresponding to the multiple slurry tank bodies and correspond one to one. The cover closing drive drives the rotating cover to close on the slurry tank body. The entire action process is difficult to implement during actual use. The cover closing mechanism requires high precision, resulting in high production and manufacturing costs and high subsequent maintenance costs.

[0007] To this end, our company has developed a magnetic impurity removal device with low manufacturing cost, large impurity removal flow rate and good effect. Utility Model Content

A group of two strip blocks 341 are symmetrically arranged on both sides of the upper surface of the top cover flange 331, and a wedge block 3411 is fixed on the strip block 341. A locking rod 342 is fixed to the position of the port flange 24 corresponding to the strip block 341;

[0026] The number of locking cover assemblies 34 is set to two. The two iron removal tanks 2 located on the left side share one locking cover assembly 34, and the two iron removal tanks 2 located on the right side share another locking cover assembly 34.

[0030] The implementation principle of a new type of slurry iron removal device in the embodiment of the present application is:

[0031] During operation, the slurry flows through the slurry channels in the four iron removal tanks 2 respectively. During this process, the magnetic impurities in the slurry can be adsorbed by the magnetic rod 333. After the slurry passes through multiple iron removal tanks 2, the magnetic impurities in the slurry can be removed layer by layer, and the iron removal and impurity removal effect is good.

[0032] The locking cover assembly 34 is provided to facilitate cleaning of the magnetic rod 333. When impurities need to be cleaned, the bidirectional locking cylinder 343 of the locking cover assembly 34 extends to drive the bracket 344 away from the iron removal tank 2, thereby driving the pressing block 345 away from the locking rod 342 and the bar block 341. At this time, the lifting cylinders 32 on both sides extend to drive the lifting plate 31 to rise, and the lifting plate 31 drives the iron removal assembly 33 to rise, thereby facilitating cleaning of the surface of the magnetic rod 333.

[0033] After cleaning, the lifting cylinders 32 on both sides are shortened, driving the top cover flange 331 to press down on the port flange 24 on the top of the iron removal tank 2. Thereafter, the two-way locking cylinders 343 in the two locking cover assemblies 34 are shortened, driving the bracket 344 to move. The bracket 344 drives the through groove 3451 on the pressure block 345 to be stuck on the locking rod 342 and the strip block 341. Under the pressure of the through groove 3451, the wedge block 3411 on the strip block 341 can pull and press the top cover flange 331 and the iron removal tank 2 together, thereby playing a sealing role. The sealing effect is good and can meet the pressure of the slurry.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
