Description

Technical Field

[0001] This utility model relates to the field of activated alumina production technology, and in particular to an activated alumina preparation and collection device. Background Technology

[0002] Activated alumina, also known as activated bauxite, is commonly used as an adsorbent, catalyst, and catalyst carrier. It features uniform particle size, a smooth surface, high mechanical strength, strong hygroscopicity (it absorbs water but does not swell or crack, maintaining its original shape), and is non-toxic, odorless, and insoluble in water and ethanol. It possesses characteristics such as porosity, high dispersibility, good adsorption performance and surface activity, and excellent thermal stability, making it widely used in petrochemical, fine chemical, biological, and pharmaceutical industries.

[0003] The process of making activated alumina balls includes drying, crushing, rapid dehydration, ball making, and calcination of raw materials. After the activated alumina balls are calcined, the broken activated alumina balls and a small amount of activated alumina powder are screened out to meet the qualified standards. However, currently, the activated alumina balls are manually screened after production, which not only has low screening efficiency, but also makes the activated alumina balls easy to be contaminated during the manual screening process. Utility Model Content

[0004] To address the aforementioned shortcomings in the existing technology, this utility model provides an activated alumina preparation and collection device. Its purpose is to solve the problems of low sieving efficiency and easy contamination of activated alumina balls during the manual sieving process, which is currently required after the activated alumina balls are made.

[0005] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0006] An active alumina preparation and collection device includes a feed box, a recovery box, a collection box, a conveying mechanism, and a suction mechanism;

[0007] The conveying mechanism includes a conveying pipe, a motor is fixedly installed at one end of the conveying pipe, an auger is provided inside the conveying pipe, the output shaft of the motor is fixedly connected to one end of the auger, and a number of evenly distributed screen holes are provided at the bottom middle of the conveying pipe.

[0008] A recycling box is provided below the screen holes. A feeding box is fixedly connected to the top of the end of the conveying pipe away from the motor. A collection box is connected to the bottom of the end of the conveying pipe away from the feeding box. An isolation net is provided at the end of the conveying pipe near the feeding box. A suction mechanism is provided on the side of the isolation net away from the conveying pipe.

[0009] Furthermore, the suction mechanism includes a mounting base on which a centrifugal dust extraction fan is fixedly mounted. An air inlet pipe is provided between the air inlet end of the centrifugal dust extraction fan and the conveying pipe, and a cylindrical cloth bag is connected to the air outlet end of the centrifugal dust extraction fan.

[0010] Furthermore, the end of the cylindrical bag furthest from the centrifugal dust extraction fan is secured with a rope.

[0011] Furthermore, a feed hopper is provided on the top of the feed box.

[0012] Furthermore, both the recycling bin and the collection bin are hinged with doors.

[0013] Furthermore, both the recycling bin and the collection bin are equipped with support legs at the bottom.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention relates to an activated alumina preparation and collection device. A feeding box is used to directly collect calcined activated alumina balls. A conveying and suction mechanism transports the activated alumina balls, and during this process, broken balls fall through the sieve holes into a recovery box for recycling. The suction mechanism draws activated alumina powder into a cylindrical cloth bag, while qualified activated alumina balls are transported to the collection box. Compared to manual collection and sieving of broken activated alumina balls, this device significantly improves sieving efficiency and eliminates the risk of contamination from manual sieving.

[0021] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0022] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figures 1 to 2 As shown, an active alumina preparation and collection device includes a feeding box 1, a recovery box 2, a collection box 3, a conveying mechanism 4, and a suction mechanism 5. Both the recovery box 2 and the collection box 3 are provided with support legs 17 at their bottoms.

[0024] The conveying mechanism 4 includes a conveying pipe 6, a motor 7 is fixedly installed at one end of the conveying pipe 6, an auger 8 is provided inside the conveying pipe 6, the output shaft of the motor 7 is fixedly connected to one end of the auger 8, and a number of evenly distributed screen holes 9 are provided at the bottom middle of the conveying pipe 6.

[0025] A recycling box 2 is located below the sieve hole 9. A feeding box 1 is fixedly connected to the top of the end of the conveying pipe 6 away from the motor 7. A feeding hopper 15 is located on the top of the feeding box 1. After the activated alumina balls are calcined, they enter the feeding box 1 through the feeding hopper 15.

[0026] Motor 7 drives auger 8 to rotate, and auger 8 drives the activated alumina balls to move. When the activated alumina balls move to the position of sieve hole 9, the broken activated alumina balls fall through the sieve hole 9 into the recycling box 2.

[0027] An isolation net 10 is provided at one end of the conveying pipe 6 near the feed box 1. The isolation net 10 is used to block the activated alumina balls. A suction mechanism 5 is provided on the side of the isolation net 10 away from the conveying pipe 6. The suction mechanism 5 includes a mounting base 11. A centrifugal dust extraction fan 12 is fixedly installed on the mounting base 11. An air inlet pipe 13 is provided between the air inlet end of the centrifugal dust extraction fan 12 and the conveying pipe 6. A cylindrical cloth bag 14 is connected to the air outlet end of the centrifugal dust extraction fan 12. The end of the cylindrical cloth bag 14 away from the centrifugal dust extraction fan 12 is fixed by a rope.

[0028] The centrifugal dust extraction fan 12, through the suction mechanism 5, sucks up a small amount of activated alumina powder and other dust from the conveying pipe 6. The activated alumina powder enters the cylindrical cloth bag 14, improving the quality of the activated alumina balls. The activated alumina powder can be poured out by untying the binding rope on the cylindrical cloth bag 14.

[0029] The bottom of the conveying pipe 6, which is away from the feed box 1, is connected to the collection box 3. The auger 8 continues to convey the screened activated alumina balls into the collection box 3.

[0030] Both recycling bin 2 and collection bin 3 are hinged with bin doors 16. Opening bin doors 16 allows the activated alumina balls to be taken out. The activated alumina balls in collection bin 3 can be packaged and stored, while the activated alumina balls in recycling bin 2 can be taken out and recycled.
