Description

Technical Field

[0001] The utility model relates to the technical field of alumina production, and particularly relates to an alumina particle screening device. Background Technique

[0002] Alumina is an inorganic substance with the characteristics of high hardness, high melting point and high boiling point. Alumina is a typical amphoteric oxide, which can be dissolved in acids to form aluminum salts (such as aluminum sulfate, aluminum nitrate, etc.), and can also be dissolved in alkalis to form meta-aluminates (such as sodium meta-aluminate, ammonium meta-aluminate, etc.). Alumina is an important inorganic compound with unique physical and chemical properties and a wide range of application fields. With the progress of science and technology and the development of industry, the preparation methods and application fields of alumina will continue to expand and improve.

[0003] In the process of alumina production, a particle screening device is required. The Chinese utility model patent with the publication number of CN220027743U discloses a particle fine powder screening device for alumina production, which includes a cylinder installed on the top of a bracket. A runner is arranged inside the cylinder, and blades are evenly installed on the outer side of the runner. A hot air pump is arranged on the side of the cylinder. The discharge pipe at the outlet of the cylinder is arranged above the screening frame. The front and rear ends of the bottom of the screening frame are respectively connected with a support column and a hydraulic cylinder through support springs. A vibration motor is installed on the side of the screening frame. By arranging a stirring mechanism composed of a runner and blades inside the cylinder, under the drive of a motor, the materials are dispersed by the blades rotating at high speed, so as to avoid the influence of the filtering and screening effect caused by the agglomeration of materials due to moisture. The screened materials fall into the collection box correspondingly, so as to realize the automatic screening and collection process of particle fine powder.

[0004] However, in the process of using this utility model, since the first screen, the second screen and the third screen are arranged side by side with each other and are inclined at the same time, when alumina particles pass through the first screen, some fine particles will be screened out. Due to the action of gravity and the vibration motor, some alumina particles fall onto the second screen without being screened, which affects the screening effect and cannot meet the production requirements. Therefore, an alumina particle screening device is proposed to solve the problems raised above. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the present utility model provides an alumina particle screening device, which has the advantage of fully screening alumina particles, and solves the problem that since the first screen, the second screen and the third screen are arranged side by side with each other, and at the same time the three are inclined, when the alumina particles pass through the first screen, some fine particles will be screened out, and due to the action of the gravity and the vibration motor, some alumina particles fall onto the second screen without being screened, which affects the screening effect and cannot meet the production requirements.

[0006] To achieve the above object, the present utility model provides the following technical solutions: An alumina particle screening device, comprising a base and a top frame fixedly connected to the top of the base. A storage bin is fixedly connected to one side of the top of the base away from the frame. A screening mechanism for multi-stage screening of alumina particles is arranged at the top of the frame;

[0007] The screening mechanism includes a screening box arranged at the top of the frame. Three screening nets extending to the front of the screening box are slidably connected inside the screening box. A vibration motor is fixedly installed on one side of the screening box close to the frame. A support spring is fixedly connected between the screening box and the opposite side of the frame. A first discharge pipe extending into the screening box is fixedly connected to one side of the screening box.

[0008] The filter hole diameters of the three screening nets increase sequentially from top to bottom. The number of the first discharge pipes is the same as the number of the screening nets.

[0009] Further, positioning blocks extending into the screening box are fixedly connected to both the left and right sides of the screening net. Positioning grooves adapted to the positioning blocks are formed on the inner wall of the screening box.

[0010] Further, a second discharge pipe extending into the frame is fixedly connected to the bottom of the screening box. A collection box extending to the front of the frame is slidably connected inside the frame. The second discharge pipe is communicated with the collection box. A feed hopper extending into the screening box is fixedly connected to the top of the screening box.

[0011] Further, a hot air blower is fixedly installed on the top of the storage bin. A jet head is fixedly installed on the inner top wall of the storage bin. A conveying pipe is fixedly connected between the hot air blower and the jet head. A feed pipe is fixedly connected to one side of the storage bin.

[0012] Further, a conveying cylinder is arranged on the top of the base. A driving motor is fixedly connected to one end of the conveying cylinder close to the base. A spiral conveyor rod extending into the conveying cylinder is fixedly connected to the output end of the driving motor.

[0013] Further, a connecting pipe is fixedly connected between the conveying cylinder and the storage bin. A discharge pipe is fixedly connected to one side of the conveying cylinder away from the connecting pipe.

[0014] Furthermore, a support frame is fixedly connected to the top of the base, and the conveying cylinder is fixedly connected to the base through the support frame.

[0015] Compared with the prior art, the present utility model provides an alumina particle screening device, which has the following beneficial effects:

[0016] 1. For this alumina particle screening device, by setting three screening meshes, the alumina particles can be continuously screened three times. At the same time, since the three screening meshes are arranged side by side, during the screening process of the alumina particles, a sufficient screening effect can be achieved. Additionally, by setting a vibration motor and support springs, the screening box can be vibrated to improve the screening efficiency. By setting three first discharge pipes and one second discharge pipe, the alumina particles after each layer of screening can be collected.

[0017] 2. For this alumina particle screening device, by setting a hot air blower and air jet nozzles, the alumina particles inside the storage bin can be dried. Then, by setting a drive motor to drive the spiral conveyor rod to rotate, the alumina particles can be conveyed into the screening box, achieving the effect of convenient feeding. This solves the problem that since the first screen, the second screen, and the third screen are arranged side by side and are inclined, when the alumina particles pass through the first screen, some fine particles will be screened out. Due to the action of gravity and the vibration motor, some alumina particles fall onto the second screen without being screened, thus affecting the screening effect and not meeting the production requirements.
