DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application (for the convenience of description and understanding, the following is Figure 2 All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] See also Figure 1-5 The present application provides a technical solution: a pretreatment screening device for preparing white corundum powder, comprising a material receiving bin 1, wherein a material stirring group 2 is arranged in the material receiving bin 1, a gap is arranged at the lower end of the material receiving bin 1, and a material guiding group 3 is arranged corresponding to the gap.

[0019] The receiving bin 1 is responsible for receiving the original alumina raw materials and can accommodate a large amount of materials at one time, reducing the need for repeated filling, thereby improving work efficiency.

[0020] The stirring group 2 is located inside the material receiving bin 1 and stirs the material during its falling process to prevent the material from forming lumps or accumulations when falling, thereby ensuring that the material can be evenly distributed, thereby improving the efficiency and effect of the subsequent processing process.

[0021] The material guide group 3 guides the material to smoothly transition from the gap of the receiving bin 1 to the subsequent processing equipment. By cooperating with the material guide adjustment card 14, the outflow rate of the material is controlled to ensure that the material can enter the next link evenly according to the predetermined flow rate, avoiding processing problems caused by material blockage or excessive inflow.

[0022] A moving group 4 is arranged below the material guiding group 3 , a lifting group 5 for adjusting the height of the air separation box 6 is arranged on the moving group 4 , and a material guiding adjustment card 14 corresponding to the material guiding group 3 is arranged at the feeding end of the air separation box 6 .

[0023] The mobile group 4 carries the related components of the air separation box 6 and the material collection box 7. At the same time, through structures such as handles 13 and wheels, the air separation box 6 and the material collection box 7 can be easily moved in the working environment, thereby improving the flexibility and convenience of operation.

[0024] The lifting group 5 is integrated on the moving group 4 to adjust the height of the air separation box 6 and the material collection box 7. By changing the position of the air separation box 6, the material flow direction and sorting effect during the air separation process can be optimized to ensure that the system can work efficiently and accurately.

[0025] The air separation box 6 utilizes the principle of aerodynamics to separate light impurities (such as dust and debris) from heavier useful materials by controlling the direction and speed of the airflow. The trapezoidal cross-section design of the air separation box 6 is conducive to forming a more effective airflow distribution, ensuring the uniformity of the airflow, thereby improving the sorting efficiency.

[0026] The material guide adjustment card 14 is arranged at the feeding end of the air separation box 6, corresponding to the material guide group 3. In order to better control the opening and closing degree of the material guide group 3, so as to ensure that the material can be evenly distributed in the air separation area, thereby improving the accuracy and efficiency of air separation.

[0027] A material collecting box 7 is arranged on one side of the air separation box 6. The air separation box 6 and the material collecting box 7 are arranged adjacent to each other. The cross-section of the air separation box 6 is a trapezoidal structure. A wind blowing component 8 is arranged on one side of the air separation box 6. The material collecting box 7 is provided with three material bins 9. A screen group 10 is arranged at the inlet end of the material bin 9.

[0028] The air separation box 6 adopts a trapezoidal cross-section structure, which is conducive to forming a more uniform and controllable air flow distribution, improving the efficiency and accuracy of air separation. The wind blowing component 8 equipped on one side of the box is the core of the air separation process. By adjusting the wind force and direction, light impurities and target materials can be effectively separated.

[0029] The material collection box 7 is arranged adjacent to the air separation box 6, and is used to receive and classify the air-selected products. Three material bins 9 are arranged inside, which are used to collect materials of different grades or types, respectively, to achieve preliminary material classification and storage.

[0030] The screen group 10 is installed at the inlet end of each material bin 9 to further screen and filter the materials to ensure that only materials that meet specific specifications can enter the corresponding bin. The aperture and shape of the screen can be customized according to the material characteristics and the required grade to achieve the best screening effect.

[0031] Furthermore, the material guiding group 3 is composed of two guide plates arranged opposite to each other, and the two guide plates are arranged closely.

[0032] It is composed of two guide plates that are placed opposite to each other and fit closely together to form a narrow channel or guide groove. It controls the flow direction of the material and ensures that the material can move smoothly and orderly along the predetermined path.

[0033] When the material enters from above or from other directions, the guide plate of the material guide group 3 will convert the free fall motion of the material into sliding along the surface of the guide plate, thereby guiding the material to move forward in a predetermined direction.

[0034] The flow of the material can be controlled by adjusting the distance between the two guide plates under the action of the material guide adjustment card 14. If the gap between the guide plates is small, the amount of material passing through will also decrease, otherwise it will increase.

[0035] Furthermore, the moving group 4 includes a bottom support bracket 11 and a box fixing seat 12 , and the upper surface of the bottom support bracket 11 is provided with a box fixing seat 12 for limiting the material collection box 7 .

[0036] Furthermore, the moving group 4 also includes a handle 13 , and the handle 13 is fixed to one side of the bottom support bracket 11 .

[0037] Furthermore, the material guiding adjustment card 14 includes a bracket plate 15, an adjustment shaft 16 and an electromagnet 17. The bracket plate 15 is provided with an adjustment shaft 16. The end of the adjustment shaft 16 is provided with a seating seat, and the seating seat is provided with an electromagnet 17.

[0038] The material guide adjustment card 14 controls the position of the electromagnet 17 by adjusting the rotation of the rotating shaft 16. The electromagnet 17 acts as an actuator to adsorb the guide plate of the material guide group 3, thereby controlling the opening and closing degree of the material guide group 3, so that the material can enter the air separation box 6 in the best way, ensuring the effective separation of light impurities and target materials.

[0039] Furthermore, the lifting group 5 includes a screw motor, a screw guide seat 18, a screw 19 and a connecting frame 20. The screw guide seat 18 is located in a support frame on the moving group 4. The screw 19 is connected to the screw guide seat 18. The screw sleeve on the screw 19 is connected to the connecting frame 20. The connecting frame 20 is slidably connected in a guide groove on the support frame, and the connecting frame 20 is connected to the air separation box 6.

[0040] When in use: a large amount of alumina raw materials are put into the receiving bin 1. Before the materials fall, the stirring group 2 starts to work to prevent the materials from agglomerating and ensure that the materials are evenly distributed in the receiving bin 1. The materials pass through the gap at the lower end of the receiving bin 1. The two guide plates of the guide group 3 are closely set to form a guide groove to ensure that the materials flow along the predetermined path and smoothly transition to the next link. Through cooperation with the guide adjustment card 14, the outflow rate of the materials can be finely controlled to ensure that the materials enter the subsequent processing equipment evenly. The operator can easily move the entire device to a suitable working position through the handle 13. The bottom support bracket 11 and the box fixing seat 12 of the moving group 4 ensure the stable fixation of the air separation box 6 and the material collection box 7. According to the processing requirements, the operator can adjust the lifting group 5, change the height of the air separation box 6, and optimize the material flow direction and sorting effect. The smooth lifting and lowering of the air separation box 6 is ensured by the linkage of the screw guide seat 18, the screw 19 and the connecting frame 20. The material enters the air separation box 6. The air blowing component 8 controls the direction and speed of the air flow by using the aerodynamic principle to effectively separate light impurities and target materials. The air-selected material enters the material collection box 7, in which the three material bins 9 are used to collect materials of different grades. The screen group 10 further screens the material to ensure that each material meets the required specifications.

[0041] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
