[0002] Brick blanks are an important intermediate link in brick factory production. During the production process, the raw materials required for the brick blanks need to be mixed. During the mixing process, the soil cannot clump, otherwise the quality of the mixed raw materials will be greatly reduced, or even fail to meet the quality requirements.

[0003] The existing mixing equipment for brick production has the following problems: The mixing efficiency of existing mixing equipment for brick raw materials is relatively low. Generally speaking, the longer the mixing time and the more appropriately the stirring speed is increased, the more evenly the raw materials are mixed.

[0010] A method for using a mixing device for producing brick blanks, comprising the following steps: Step 1: The raw materials of the bricks are poured into the mixing barrel through the feed port, and the driving motor drives the driving main pipe to rotate through the power end, and the driving main pipe drives the stirring rod through the stirring block to stir the raw materials inside the mixing barrel; Step 2: The electromagnet is energized to generate magnetism, and the electromagnet and the stressed magnet are arranged with opposite poles.

The magnetically expanded soft iron is fixed inside the magnetic guide port and adsorbs the stressed magnet through magnetic force. The stressed magnet drives the deflection angle of the arc plate to increase, and the slope of the head-on contact of the raw materials containing particles increases during rotation, thereby increasing the blocking force on the granular raw materials, slowing down the rotation speed of the granular raw materials, and reducing the chance of particles in the raw materials being worn.

[0011] The beneficial effects achieved by adopting the above structure are as follows: Compared with the prior art, the present invention adopts a combination of a rotating structure and a slope adjustment structure. Through the arrangement of a magnetically conductive mixing mechanism and an anti-damage resistance increasing mechanism, the driving mechanism, the stirring mechanism, the magnetic flux mechanism, the return force mechanism and the deceleration mechanism can slow down the movement speed of particles in the raw materials, reduce the wear probability of the granular raw materials, improve the mixing efficiency of the raw materials for brick production, ensure the performance of the raw materials after mixing, and change the broken surface through the magnetic adsorption intensity. The contact slope between the raw materials and the wear-resistant rubber layer can be adjusted according to the stirring time of the raw materials, thereby gradually slowing down the movement speed of the granular raw materials, reducing the wear probability of the granular raw materials in the mixing process, and ensuring the strength of the bricks after forming. As the current of the electromagnet increases, the magnetic adsorption capacity of the magnetically expanded soft iron is enhanced. The magnetically expanded soft iron is fixed inside the magnetic conductive port and absorbs the stressed magnet by magnetic force. The stressed magnet drives the deflection angle of the arc plate to increase, and the slope of the head-on contact of the raw materials containing particles increases during rotation, thereby improving the blocking force against the granular raw materials.

[0020] A controller 30 is disposed on the side wall of the mixing barrel 1 .

[0021] The controller 30 is electrically connected to the driving motor 5 and the electromagnet 15 respectively.

[0022] A method for using a mixing device for producing brick blanks, comprising the following steps: Step 1: The raw materials of the bricks are poured into the mixing barrel 1 through the feed port 2, the driving motor 5 drives the driving main pipe 7 to rotate through the power end, and the driving main pipe 7 drives the stirring rod 10 through the stirring block 9 to stir the raw materials in the mixing barrel 1; Step 2: The electromagnet 15 is energized to generate magnetism, and the electromagnet 15 and the stressed magnet 29 are arranged with opposite poles. The electromagnet 15 magnetizes the magnetic soft iron rod 16 and the soft iron slip ring 17, and the soft iron slip ring 17 magnetizes the magnetic soft iron 12 through the conduction port 18. The magnetic soft iron 12 and the stressed magnet 29 are arranged with opposite poles. The magnetic soft iron 12 adsorbs the stressed magnet 29 through magnetic force, and the stressed magnet 29 drives the arc plate 26 to deflect. The arc plate 26 drives the wear-resistant rubber layer 27 to change the angle with the inner wall of the mixing barrel 1 through the deformation of the return spring 24. The wear-resistant rubber layer 27 changes from a relatively horizontal state to an inclined state, and the wear-resistant rubber layer 27 blocks and decelerates the particles in the mixed raw materials through its own buffering performance; Step three: As the stirring speed and time of the raw materials increase, the current delivered to the inside of the electromagnet 15 is increased. As the current of the electromagnet 15 increases, the magnetic adsorption capacity of the magnetically expanded soft iron 12 is enhanced. The magnetically expanded soft iron 12 is fixed inside the magnetic guide port 11 and adsorbs the stressed magnet 29 by magnetic force. The stressed magnet 29 drives the deflection angle of the arc plate 26 to increase, and the slope of the head-on contact of the raw materials containing particles during rotation increases, thereby increasing the blocking force on the granular raw materials, slowing down the rotation speed of the granular raw materials, and reducing the probability of particles in the raw materials being worn.

[0023] When in use, initially, the arc plate 26 and the inner wall of the mixing barrel 1 are at the minimum distance, and the arc plate 26 is located on one side of the inner wall of the mixing barrel 1. The operator pours the raw brick material into the mixing barrel 1 through the feed port 2, and then the controller 30 controls the drive motor 5 to start, and the drive motor 5 drives the drive main pipe 7 to rotate through the power end, and the drive main pipe 7 drives the stirring rod 10 through the stirring block 9 to stir the raw materials inside the mixing barrel 1; During the mixing process of the raw materials for bricks, particles with a larger specific gravity are easily affected by gravity and move toward the inner wall of the mixing barrel 1. Since a wear-resistant rubber layer 27 is provided on one side of the inner wall of the mixing barrel 1, the particle raw materials moved to the inner wall of the mixing barrel 1 are in contact with the wear-resistant rubber layer 27, thereby reducing the probability of the particles contacting the inner wall of the mixing barrel 1 and avoiding wear of the particle raw materials. The driving motor 5 drives the driving main pipe 7 to accelerate the stirring speed of the raw materials through the stirring rod 10, and the controller 30 controls the electromagnet 15 to start. The electromagnet 15 is energized to generate magnetism. The electromagnet 15 and the stressed magnet 29 are arranged with different poles. The electromagnet 15 magnetizes the magnetic soft iron rod 16 and the soft iron slip ring 17. The soft iron slip ring 17 magnetizes the magnetic expansion soft iron 12 through the conduction port 18. The magnetic expansion soft iron 12 and the stressed magnet 29 are arranged with different poles. The magnetic expansion soft iron 12 attracts the stressed magnet 29 through magnetic force. The stressed magnet 29 drives the arc plate 26 to deflect. The arc plate 26 drives the wear-resistant rubber layer 27 to change the angle with the inner wall of the mixing barrel 1 through the deformation of the return spring 24. The wear-resistant rubber layer 27 changes from a relatively horizontal state to an inclined state. The wear-resistant rubber layer 27 blocks and decelerates the particles in the mixed raw materials through its own buffering performance; As the stirring speed and time of the raw materials increase, in order to prevent the particles in the raw materials from being subjected to the effects of stirring and friction, which may lead to increased surface wear and reduced particle size, and affect the subsequent brick forming performance, the controller 30 increases the current delivered to the inside of the electromagnet 15. As the current of the electromagnet 15 increases, the magnetic adsorption capacity of the magnetically expanded soft iron 12 is enhanced. The magnetically expanded soft iron 12 is fixed inside the magnetic guide port 11 and adsorbs the stressed magnet 29 by magnetic force. The stressed magnet 29 drives the deflection angle of the arc plate 26 to increase, and the slope of the head-on contact of the raw materials containing particles increases during rotation, thereby increasing the blocking force on the granular raw materials, slowing down the rotation speed of the granular raw materials, and reducing the probability of wear of the particles in the raw materials, thereby completing the mixing operation of the brick raw materials; the above operation can be repeated the next time it is used.

[0024] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0025] The above is a description of the present solution and its implementation methods, which is not restrictive. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the creative purpose of the present solution, they should all fall within the protection scope of the present solution.
