Description

Technical Field

[0001] The invention belongs to the technical field of alumina production and relates to an alumina roasting production and conveying device. Background Art

[0002] Alumina is an inorganic substance, a highly hard compound with a melting point of 2054°C and a boiling point of 2980°C. It forms an ionic crystal that ionizes at high temperatures. Alumina is a stable oxide of aluminum and is also known as bauxite in the mining, ceramics, and materials science industries. It is a water-insoluble white solid that is odorless, tasteless, and extremely hard. It absorbs moisture readily but does not deliquesce. Alumina is a typical amphoteric oxide, slightly soluble in acids and alkalis and corrosion-resistant. It is used as an analytical reagent, dehydrator for organic solvents, adsorbent, catalyst for organic reactions, abrasive, polishing agent, raw material for aluminum smelting, and refractory material.

[0003] In the production and preparation of alumina, the raw materials are generally first prepared into a slurry after a series of processes such as crushing, lime digestion, grinding, precipitation separation, washing, filtration and evaporation. The slurry is then pumped to a disc filter for separation and washing. The washed filter cake is sent to a roasting furnace via a belt conveyor for roasting to produce alumina. Before being sent to the roasting furnace for roasting, the moisture in the filter cake is usually preheated and dried to remove most of the moisture in the material, thereby improving the efficiency of subsequent roasting. However, at present, the water-containing filter cake is directly sent to the preheating device via a belt conveyor to dry the moisture without prior dehydration treatment, resulting in slow efficiency during the drying process and high energy consumption. Therefore, we have proposed an alumina roasting production conveying device to solve the above-mentioned problems. Summary of the Invention

The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and the following embodiments and features in the embodiments can be combined with each other without conflict.

[0036] Example 1

[0037] like Figure 1 - Figure 6 As shown, an alumina roasting production conveying device includes four support plates 2, the tops of the four support plates 2 are rotatably connected to the same conveying seat 1, one side of one of the support plates 2 is fixedly connected to a mounting plate 3, the top of the mounting plate 3 is fixedly connected to a driving motor 9, a transmission gear 10 is fixedly sleeved on the output shaft of the driving motor 9, and the outer wall bottom of the conveying seat 1 is annularly fixedly connected to multiple support rods 8 at equal intervals, and the ends of the multiple support rods 8 away from the conveying seat 1 are fixedly connected to the same outer gear ring 11 meshing with the transmission gear 10. When the driving motor 9 is started, the transmission gear 10 and the outer gear ring 11 can be meshed with each other. The meshing movement of the ring 11 drives the conveying seat 1 to rotate to complete the feeding; the top of the conveying seat 1 is provided with four material receiving troughs 7 at equal intervals in a ring shape for conveying materials, and a group of dehydration mechanisms are provided in the four material receiving troughs 7 for squeezing and dehydrating the fallen materials, and the dehydrated materials can be automatically discharged. A material discharge mechanism is provided on the top of the conveying seat 1 for conveying the materials to the four material receiving troughs 7 respectively, and a water receiving mechanism is provided below the conveying seat 1 for collecting the squeezed water. A material receiving mechanism is provided below the conveying seat 1 for receiving and conveying the automatically discharged materials.

[0038] In one aspect of this embodiment, the unloading mechanism includes a plurality of connecting columns 12 fixedly connected to the top of the conveying seat 1, the top ends of the plurality of connecting columns 12 are fixedly connected to the same unloading seat 5, and the top of the unloading seat 5 is annularly and equidistantly provided with four arc-shaped unloading troughs 6, and the bottom walls of the four unloading troughs 6 are all penetrated by a unloading pipe 13 fixedly connected thereto, and the bottom ends of the four unloading pipes 13 extend into the four receiving troughs 7 respectively. When the driving motor 9 is started to drive the conveying seat 1 to rotate, the unloading seat 5 can be driven to rotate at the same time, and the material is transported through the conveying pipe, and the conveying pipe is arranged above the unloading trough 6. The material is transported to the unloading trough 6 through the conveying pipe, and then falls into the feeding trough 7 from the unloading pipe 13; since the unloading seat 5 rotates synchronously with the conveying seat 1, the material can be intermittently transported to the four receiving troughs 7 through the four unloading troughs 6 as the conveying seat 1 rotates; in order to facilitate the falling and conveying of the material, the bottom wall of the unloading trough 6 can be set to an arc surface, and a vibration motor can also be set at the bottom of the unloading seat 5 to enable the unloading seat 5 to realize vibration unloading during the rotation process, as long as it can be ensured that the material can slide down automatically.

[0039] The present invention can be used in the field of alumina roasting production and conveying devices, and can also be applied to other fields of the present invention.

[0040] Example 2

[0041] This embodiment is a further improvement of the previous embodiment: Figure 1 - Figure 9 As shown, the dehydration mechanism includes a through hole 14 opened on the inner wall of one side of the material receiving trough 7, the top wall of the through hole 14 is sealed and slidably connected to a sliding plate 16, and one side of the sliding plate 16 extends outward, and the bottom side of the sliding plate 16 is fixedly connected to a pushing plate 19 that is sealed and fits with the inner wall of the through hole 14, and a water filter plate 15 used in conjunction with the pushing plate 19 is fixedly connected to the lower part of the interior of the material receiving trough 7. As the conveying seat 1 rotates, when the lower material chute 6 no longer corresponds to the conveying pipe, the material is no longer received in the receiving chute 7, and the material falls on the water filter plate 15 in the receiving chute 7 and accumulates. As the conveying seat 1 continues to rotate, when it rotates to a certain position, the pushing plate 19 will move, and its bottom will fit on the top of the water filter plate 15 and move, thereby squeezing the material, thereby achieving the dehydration effect, and the squeezed water is directly filtered out through the water filter plate 15; when the pushing plate 19 moves, it will drive the sliding plate 16 to extend inward and move synchronously, so as to catch the material that has not completely fallen in the upper lower material chute 6, and prevent the material from falling on the side of the pushing plate 19 close to the through hole 14. When the pushing plate 19 drives the sliding plate 16 to move back, the material caught on the sliding plate 16 can be automatically scraped off onto the water filter plate 15.

[0042] In one aspect of this embodiment, a fixing plate 17 is fixedly connected to the inside of the through hole 14, and the inner side surface of the fixing plate 17 contacts the outer side surface of the push plate 19. A push rod 18 slides through one side of the fixing plate 17, and one end of the push rod 18 is fixedly connected to one side of the push plate 19. The other end of the push rod 18 extends outward and is fixedly sleeved with a fixing ring 20. The outer wall of the push rod 18 is sleeved with a return spring 21, and the two ends of the return spring 21 are fixedly connected to one side of the fixing ring 20 and one side of the fixing plate 17 respectively; the conveying device also includes an arc-shaped strip plate 22 used in conjunction with the push rod 18, and the bottom of the arc-shaped strip plate 22 is fixedly connected to a plurality of support rods 41. Figure 5 As shown, the conveying seat 1 receives the material through the material receiving trough 7, and as the conveying seat 1 rotates, it drives the push rod 18 to move. When one end of the push rod 18 moves and contacts with the inner side surface of the arc-shaped strip 22, the push rod 18 can move inward and squeeze the reset spring 21, and the push rod 18 simultaneously drives the push plate 19 and the sliding plate 16 to move, thereby achieving the effect of automatic squeezing and dehydrating the material.

[0043] In one aspect of this embodiment, the bottom wall of the receiving trough 7 is provided with a drainage groove 29 located below the water filter plate 15. A drainage pipe 30 is fixedly connected to the bottom wall of the drainage groove 29. The squeezed water can flow along the water filter plate 15 into the drainage groove 29 below and finally flow out through the drainage pipe 30.

[0044] Example 3

[0045] This embodiment is a further improvement of the previous embodiment: Figure 1 - Figure 8 As shown, the water receiving mechanism includes three support columns 28, the top ends of the three support columns 28 are fixedly connected to the same annular water receiving groove 33, and the bottom ends of the four drain pipes 30 all extend into the annular water receiving groove 33. A water outlet pipe 34 is fixedly connected to the bottom side of the annular water receiving groove 33, and a first valve body 35 is installed on the water outlet pipe 34. By providing the annular water receiving groove 33, the drain pipe 30 can be driven to always perform a circular rotational motion in the annular water receiving groove 33 during the rotation of the conveying base 1, thereby ensuring that the squeezed water can always flow into the annular water receiving groove 33 for centralized collection. At the same time, the collected water is discharged outward from the water outlet pipe 34, and the opening and closing of the water outlet pipe 34 is controlled by the first valve body 35.

[0046] Example 4

[0047] This embodiment is a further improvement of the previous embodiment: Figure 1 - Figure 9As shown, a square hole 4 is provided on the top of the conveying seat 1, and a discharge port 23 connected to the square hole 4 is provided on the inner wall of the side of the material receiving trough 7 away from the through hole 14. A rotating rod 24 is rotatably connected to the upper part of the inner part of the discharge port 23, and a fixed sleeve on the outer wall of the rotating rod 24 is provided with a baffle 25 for blocking the discharge port 23. Two grooves 31 are symmetrically provided on the four inner walls of the square hole 4, and the two ends of the rotating rod 24 are respectively rotated to extend into the corresponding two grooves 31 and are rotatably connected to the inner walls of the grooves 31. One end of the rotating rod 24 located in the two grooves 31 is provided with a torsion spring 26, and the two ends of the torsion spring 26 are respectively fixedly connected to the inner wall of the groove 31 and the outer wall of the rotating rod 24. Since the through hole 14 is arranged opposite to the discharge port 23, and the discharge port 23 is connected to the square hole 4, when the push rod 18 moves and contacts the inner side of the arc strip 22, the push plate 19 will be driven by the push rod 18 to move closer to the baffle plate 25, and the push plate 19 will first squeeze and dehydrate the material. Figure 5 As shown, as the push rod 18 continues to move on the inner side of the curved strip 22, the push plate 19 will continue to move closer to the position of the baffle plate 25, and through the extrusion force, it pushes the material to move and drives the baffle plate 25 to rotate, and causes the torsion spring 26 to twist. When the baffle plate 25 rotates, the material will fall directly into the square hole 4, thereby achieving the effect of automatic discharging; when the push rod 18 is out of contact with the curved strip 22, it will drive the push plate 19, the sliding plate 16 and the push rod 18 to reset and move under the elastic force of the reset spring 21, and at the same time, the baffle plate 25 will be driven to reset and rotate under the elastic force of the torsion spring 26, and the discharge port 23 will be blocked again.

[0048] In one aspect of this embodiment, the material receiving mechanism includes a receiving hopper 38 that contacts the bottom of the conveying seat 1, and the receiving hopper 38 is used in conjunction with the square hole 4. The bottom of the receiving hopper 38 is integrally provided with a feeding pipe 37. The outer wall of the feeding pipe 37 is annular and fixedly connected to a plurality of second connecting rods 36, and the other ends of the plurality of second connecting rods 36 are fixedly connected to the inner side of the annular water receiving trough 33. A second valve body 39 is installed on the feeding pipe 37. The second connecting rod 36 can stably install the feeding pipe 37 and the receiving hopper 38 on the annular water receiving trough 33, and the conveying seat 1 can be rotated on the top of the receiving hopper 38, so that the material discharged from the discharge port 23 falls into the feeding hopper 38 through the square hole 4, and is finally transported from the feeding pipe 37. The opening and closing of the feeding pipe 37 is controlled by the second valve body 39.

[0049] Example 5

[0050] This embodiment is a further improvement of the previous embodiment: Figure 1 - Figure 9As shown, the inner wall of the receiving hopper 38 is fixedly connected to a plurality of first connecting rods 32, and the top ends of the plurality of first connecting rods 32 are fixedly connected to the same arc-shaped plate 40. The four retaining plates 25 are fixedly connected to the side close to the square hole 4 with a limit rod 27 that intermittently contacts the arc-shaped plate 40. In order to improve the contact strength of the retaining plate 25 during the dehydration and extrusion process, the arc-shaped plate 40 is provided, which is fixedly connected to the upper part of the receiving hopper 38 through the first connecting rod 32 and is located inside the square hole 4. Figure 5 As shown, when the material is received through the discharge chute 6, the material falls into the receiving chute 7 through the discharge pipe 13. At this time, the limiting rod 27 on the corresponding baffle plate 25 conflicts with the outer side surface of the curved plate 40, so that the material can fall stably on the water filter plate 15 for accumulation, and with the rotation of the conveying seat 1, the baffle plate 25 is driven to rotate synchronously, and the limiting rod 27 always conflicts with the outer side surface of the curved plate 40. At this time, the push plate 19 is driven to move by the supporting rod 18. When the material is squeezed and dehydrated, the baffle plate 25 is restricted and will not rotate, which can enable the material to be better dehydrated. After squeezing and dehydration, the push plate 19 continues to move, and the limiting rod 27 is disengaged from the conflict with the curved plate 40, releasing the rotation limit of the baffle plate 25, and then under the action of the extrusion force, the baffle plate 25 is pushed to rotate, thereby achieving the effect of automatic discharging.

[0051] However, as is well known to those skilled in the art, the working principle and wiring method of the drive motor 9 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions, which should all be included in the scope of the claims of the present invention.
