Description

Technical Field

[0001] The invention relates to the technical field of alumina preparation, in particular to a conveying system for alumina screening. Background Art

[0002] Alumina particles are a compound formed by the combination of aluminum and oxygen, usually appearing as colorless or white fine particles. Because alumina does not react with most chemicals at high temperatures and is not easy to decompose or release adsorbed moisture, alumina is mostly used as a desiccant in laboratories and industries to remove moisture from gases and liquids. In the process of preparing alumina particles, the alumina particles will be screened so that alumina of different particle sizes can be separated according to specific requirements, and the alumina particles are sent to the screen by conveying equipment to quickly transport the alumina to the next processing link, reducing the time of manual handling and improving the work efficiency of the entire production line.

[0003] However, there are currently the following disadvantages in the transportation of alumina: 1. When transporting alumina particles to the screening site, a transmission belt is usually used to continuously transport the alumina particles. Alumina particles have a high hardness. Long-term use of the transmission belt will cause belt wear, thereby increasing maintenance costs and increasing the frequency of replacement. In addition, alumina particles will generate dust during the transportation process, which not only affects environmental hygiene, but may also cause potential harm to workers' health; 2. In the process of transporting alumina particles, because the alumina particles are exposed to the air for a long time, the alumina particles will absorb moisture, thereby causing changes in the physical properties of the particles, affecting subsequent processing or application, and when the alumina is damp or the temperature changes too much, it will cause the particles to stick together and form lumps, affecting subsequent screening processing.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1.

[0017] 2. The conveying system for alumina screening uses a transport mechanism and a conversion mechanism in coordination with each other, and adopts multiple sets of intermittently switched transport channels to quickly seal and transport the alumina screen, shortening the time that the alumina particles are exposed to the air for a long time, thereby reducing the risk of alumina particles absorbing moisture.

[0018] 3. The conveying system for alumina screening cooperates with the conversion mechanism and the drying mechanism to dry the falling alumina once during transportation, and then spreads and dries the falling alumina through up and down reciprocating movement.

[0019] 4. The conveying system for alumina screening dries the inner side of the channel where the alumina particles are not transported by setting a drying mechanism, which effectively reduces the humidity in the channel, prevents the particles from absorbing moisture during transportation, keeps the particles dry, and the dry channel can reduce particle adhesion and accumulation, increase particle fluidity, and ensure the smooth flow of alumina particles during transportation. At the same time, drying can also prevent particles from agglomerating and ensure the consistency of the material. BRIEF DESCRIPTION OF THE DRAWINGS

The lower end of the connecting pipe 413 is fixedly connected to the feed hole 411. The lower end surface of the transport cylinder 2 is fixedly installed with a discharge hole 414 corresponding to the feed hole 411.

[0033] See also Figure 2 , Figure 3 and Figure 4 The transport distribution part 42 includes a conversion column 421, a fixed rotating drum 422 and a transport channel 423. The transport drum 2 is provided with a fixed rotating drum 422 coaxial with the fixed rotating drum 422 through a bearing. The fixed rotating drum 422 is fixedly sleeved with a conversion column 421 located in the transport drum 2. The conversion column 421 is provided with a plurality of transport channels 423 arranged in a circumferential array. The number of the transport channels 423 is twice the number of the feed holes 411.

[0034] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The driving part 51 includes a central rotating drum 511 and a first motor 512. The central rotating drum 511 coaxial with the fixed rotating drum 422 and located inside the fixed rotating drum 422 is installed on the transport drum 2 through a bearing. The first motor 512 is fixedly installed on the upper end surface of the transport drum 2. The output end of the first motor 512 is connected to the upper end of the central rotating drum 511 through a first gear set.

[0035] See also Figure 2 , Figure 4 and Figure 5The locking portion 52 includes a socket 521, a lock hole 522 and a spring rod 523. A plurality of groups of sockets 521 are evenly arranged on the annular wall of the central rotating cylinder 511 from top to bottom, and each group includes a plurality of sockets 521 that are penetrated in a circular array. Lock holes 522 corresponding to the sockets 521 are arranged on the inner annular wall of the fixed rotating cylinder 422. A spring rod 523 is slidably installed in the socket 521. The spring rod 523 passes through the socket 521 and is plugged into the corresponding lock hole 522; the spring rod 523 is composed of a rod member slidably connected to the socket 521, and a spring that is sleeved on the outside of the rod member and connected to the inner annular wall of the central rotating cylinder 511.

[0036] See also Figure 2 , Figure 3 and Figure 5 The matching part 53 includes a connecting rod 531, a spindle block 532 and an electric push rod 533. The electric push rod 533 is fixedly installed on the upper end of the central rotating cylinder 511. The telescopic end of the electric push rod 533 is fixedly installed with a connecting rod 531 located in the central rotating cylinder 511. The connecting rod 531 is fixedly sleeved with spindle blocks 532 corresponding to multiple groups of sockets 521 one by one.

[0037] See also Figure 1-Figure 7 During specific operation, when the alumina particles need to be transported, the alumina particles to be transported are poured into the feed trough 412, and the alumina particles are divided into multiple portions through the connecting pipe 413 and enter different connecting pipes 413, and the alumina particles falling from the connecting pipe 413 will enter the transport cylinder 2 through the corresponding feed hole 411. Since the first motor 512 is in an unstarted state at this time, the transport channel 423 is just located below the feed hole 411, so that the falling alumina particles pass through the transport channel 423 and reach the discharge hole 414, and enter the discharge cone barrel 3 after passing through the discharge hole 414.

[0038] After the transport channel 423 has transported the alumina particles for a certain period of time, the electric push rod 533 is started to make its telescopic end descend with the connecting rod 531, so that the corresponding spring plug rod 523 is pushed out of the socket 521 through the descending of the spindle block 532, and when the spring plug rod 523 is inserted into the lock hole 522, the central rotating drum 511 and the fixed rotating drum 422 are locked, so that the central rotating drum 511 can rotate with the conversion column 421, and then the first motor 512 is started to rotate the conversion column 421 through the first gear group, so that the transport channel 423 for the alumina particles rotates around the central rotating drum 511, and moves the adjacent transport channel 423 to the bottom of the feed hole 411, so as to complete the switching of the transport channel 423 for transporting the alumina particles, thereby using multiple groups of intermittently switched transport channels 423 to quickly seal and transport the alumina particles, reduce the time that the alumina particles are exposed to the air for a long time, and improve the overall transportation efficiency through continuous transportation.

[0039] Then, the electric push rod 533 is started in reverse to make it rise with the spindle block 532. At this time, the squeezing of the spring plug 523 disappears, so that the central rotating drum 511 and the fixed rotating drum 422 can be unlocked, so that the rotation of the central rotating drum 511 no longer drives the conversion column 421 to rotate synchronously.

[0040] See also Figure 2 , Figure 3 , Figure 4 and Figure 7 The material spreading part 54 includes a reciprocating screw 541, a material spreading block 542 and a guide telescopic rod 543. The reciprocating screw 541 located in the material discharge cone barrel 3 is fixedly installed at the lower end of the central rotating cylinder 511. A supporting truncated cone connected to the reciprocating screw 541 through a bearing is fixedly installed in the material discharge cone barrel 3. A plurality of guide telescopic rods 543 are evenly distributed on the supporting truncated cone. A material spreading block 542 is fixedly installed on the upper ends of the plurality of guide telescopic rods 543. The material spreading block 542 is threadedly connected to the reciprocating screw 541. The material spreading block 542 consists of a cone at the upper end and a truncated cone at the lower end.

[0041] During specific operation, when the first motor 512 rotates the central rotating cylinder 511, it will also cause the reciprocating screw 541 to rotate, and the guide telescopic rod 543 limits the rotation of the material spreading block 542. Therefore, the rotation of the reciprocating screw 541 will cause the material spreading block 542 to move back and forth up and down. At this time, the alumina particles entering the discharge cone barrel 3 from the discharge hole 414 will first contact the cone at the upper end of the material spreading block 542, thereby dispersing the alumina particles. Subsequently, the dispersed alumina particles will move downward along the inner wall of the discharge cone barrel 3, and the material spreading block 542 that moves back and forth up and down will disperse the falling alumina particles through continuous movement, so that the alumina particles fall dynamically and quickly, thereby preventing the alumina particles from accumulating and blocking the lower end outlet of the discharge cone barrel 3.

[0042] See also Figure 2 , Figure 3 and Figure 4 The drying section 61 includes a first annular tube 611 and a first drying tube 612. The first annular tube 611 is fixedly installed on the outer annular wall of the transport cylinder 2. Drying holes located between adjacent feed holes 411 are fixedly opened on the upper end surface of the transport cylinder 2. The drying holes correspond to the transport channels 423 located between adjacent feed holes 411. The first annular tube 611 is fixedly installed with first drying tubes 612 corresponding to the drying holes one by one. The upper ends of the first drying tubes 612 are fixedly connected to the corresponding drying holes.

[0043] See also Figure 2 , Figure 4 and Figure 6The drying section 62 includes a ring-through pipe 621, a connecting pipe 622 and a first ventilation pipe 623. The lower end of the transport cylinder 2 is fixedly installed with a ring-through pipe 621 located outside the discharge hole 414. The inner ring wall of the discharge hole 414 is evenly provided with a plurality of first ventilation pipes 623 connected with the corresponding ring-through pipes 621. The ring-through pipe 621 is connected with the first ring pipe 611 through the connecting pipe 622.

[0044] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 The anti-knot portion 63 includes a second annular tube 631, a second drying tube 632 and a second ventilation tube 633. A second annular tube 631 connected to the first annular tube 611 is fixedly installed on the outer annular wall of the discharge cone barrel 3. A plurality of second drying tubes 632 located at the upper end of the second annular tube 631 are fixedly installed on the outer annular wall of the discharge cone barrel 3 in a circumferential array. The second drying tube 632 is connected to the second annular tube 631. A plurality of second ventilation tubes 633 that penetrate the inner annular wall of the discharge cone barrel 3 are evenly arranged on the second drying tube 632.

[0045] During specific operation, after the transport mechanism 4 cooperates with the conversion mechanism 5 to complete the conversion of the transport channel 423, the transport channel 423 for transporting alumina particles will be located directly below the drying hole. At this time, the external dryer is started to flow hot air into the first ring tube 611, and then the transport channel 423 for transporting alumina particles is dried through the first drying tube 612, thereby effectively reducing the humidity in the channel, preventing subsequent alumina particles from absorbing moisture during transportation, and helping to maintain the dry state of the alumina particles. In addition, the dry channel can reduce the probability of adhesion and accumulation of alumina particles, which is beneficial to increasing the fluidity of the alumina particles.

[0046] Secondly, the hot air flow will enter the annular pipe 621 through the connecting pipe 622 and be ejected through the first ventilation pipe 623, thereby drying the aluminum oxide particles passing through the discharge hole 414. At the same time, the hot air flow will enter the second drying pipe 632 through the second annular pipe 631, and in the process of the spreading part 54 moving up and down to spread the aluminum oxide particles in the discharge cone barrel 3, the hot air flow will also cooperate with the spreading part 54 to dry the aluminum oxide particles again, so as to more effectively remove moisture from the particles, shorten the overall drying time, and improve production efficiency.

[0047] See also Figure 1-Figure 7 Working principle: When the alumina particles need to be transported, the alumina particles to be transported are poured into the feed trough 412, and the alumina particles are transported through the transport mechanism 4.

[0048] After the transport channel 423 transports the alumina particles for a certain period of time, the electric push rod 533 is started to switch the transport channel 423 for transporting the alumina particles through the transport mechanism 4 and the conversion mechanism 5, so that a plurality of groups of intermittently switched transport channels 423 are used to quickly seal and transport the alumina particles. At the same time, the spreading part 54 will continuously disperse the alumina particles through the spreading block 542 that moves back and forth up and down, so that the alumina particles fall quickly.

[0049] After the transport mechanism 4 cooperates with the conversion mechanism 5 to complete the conversion of the transport channel 423, the external dryer is started to flow hot air into the first ring tube 611, and then the transport channel 423 for transporting the alumina particles is dried through the first drying tube 612, thereby effectively reducing the humidity in the channel, and the hot air flow will also pass through the drying section 62 to dry the alumina particles passing through the discharge hole 414. At the same time, the hot air flow will also pass through the anti-knot section 63 and the spreading section 54 to dry the alumina particles again, thereby more effectively removing moisture from the particles.
