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 high-hardness compound, with a melting point of 2054°C and a boiling point of 2980°C. It is an ionized crystal that can be ionized at high temperatures. Alumina is a stable oxide of aluminum, also known as alumina in mining, ceramics and materials science. Properties: a white solid that is insoluble in water, odorless, tasteless, extremely hard, and easy to absorb moisture without deliquescing. Alumina is a typical amphoteric oxide, slightly soluble in acid and alkali and resistant to corrosion. It is used as an analytical reagent, dehydration of organic solvents, adsorbent, organic reaction catalyst, abrasive, polishing agent, raw material for smelting aluminum, and refractory material.

[0003] In the production and preparation of alumina, the raw materials are generally first prepared into slurry after a series of processes such as crushing, lime digestion, grinding, precipitation separation, washing, filtering and evaporation, and then the slurry is pumped to a disc filter for separation and washing. The washed filter cake is sent to a roasting furnace through 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 through a belt conveyor to dry the moisture without prior dehydration treatment, which makes the efficiency relatively slow during the drying process and the energy consumption is high. Therefore, we propose 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 only illustrate the basic concept of the present invention in a schematic manner, 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 comprises 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, a plurality of support rods 8 are fixedly connected to the bottom of the outer wall of the conveying seat 1 in an annular shape and equidistantly, and the ends of the plurality of 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, and the driving motor 9 can be started through the transmission gear 10 and the outer gear ring 11 meshing with the transmission gear 10. 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 grooves 7 equidistantly arranged in an annular shape for conveying materials, and each of the four material receiving grooves 7 is provided with a group of dehydration mechanisms for squeezing and dehydrating the fallen materials, and the dehydrated materials can be automatically discharged. The top of the conveying seat 1 is provided with a material unloading mechanism for conveying the materials to the four material receiving grooves 7 respectively, and a water receiving mechanism is provided below the conveying seat 1 for collecting the squeezed water, and a material receiving mechanism is provided below the conveying seat 1 for receiving and conveying the automatically discharged materials.

[0038] In one aspect of the present 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, the top of the unloading seat 5 is annularly provided with four arc-shaped unloading troughs 6 equidistantly spaced from each other, the bottom walls of the four unloading troughs 6 are all penetrated by unloading pipes 13 fixedly connected thereto, and the bottom ends of the four unloading pipes 13 extend into 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. 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 receiving 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, so that the unloading seat 5 can 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 - Fig. 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 sealingly and slidably connected with 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 with a pushing plate 19 that is sealingly fitted 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 trough 6 no longer corresponds to the conveying pipeline, the receiving trough 7 no longer receives materials, and the materials fall on the water filter plate 15 in the receiving trough 7 and accumulate. 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 materials, 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 and move inward synchronously, so as to catch the materials that have not completely fallen in the upper lower material trough 6, and prevent the materials 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 materials caught on the sliding plate 16 can be automatically scraped onto the water filter plate 15.

[0042] In one aspect of the present 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 is slidably passed through one side of the fixing plate 17, one end of the push rod 18 is fixedly connected to one side of the push plate 19, and 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 reset spring 21, and the two ends of the reset spring 21 are respectively fixedly connected to one side of the fixing ring 20 and one side of the fixing plate 17; the conveying device also includes an arcuate strip plate 22 used in conjunction with the push rod 18, and a plurality of support rods 41 are fixedly connected to the bottom of the arcuate strip plate 22. Figure 5 As shown, the conveying seat 1 receives the material through the material receiving groove 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 plate 22, the push rod 18 can move inward and squeeze the return 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, and a drainage pipe 30 is fixedly connected to the bottom wall of the drainage groove 29. The squeezed water can flow into the drainage groove 29 below along the water filter plate 15, and finally flow out from 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 drainage pipes 30 extend into the annular water receiving groove 33, and 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 drainage pipe 30 can be driven to always make a circular rotation in the annular water receiving groove 33 during the rotation of the conveying seat 1, thereby ensuring that the squeezed water can always flow into the annular water receiving groove 33 for centralized collection, and 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 - Fig. 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 baffle plate 25 for blocking the discharge port 23 is fixedly sleeved on the outer wall of the rotating rod 24. Two grooves 31 are symmetrically provided on the inner walls of the four sides of the square hole 4, and the two ends of the rotating rod 24 are respectively rotated and extended into the corresponding two grooves 31, and are rotatably connected to the inner walls of the grooves 31, and one end of the rotating rod 24 located in the two grooves 31 is sleeved 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, during the movement and contact between the push rod 18 and the inner side surface 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 arc-shaped strip 22, the push plate 19 will continuously move closer to the position of the baffle plate 25, and through the extrusion force, push the material to move and drive the baffle plate 25 to rotate, and cause the torsion spring 26 to twist. When the baffle plate 25 rotates, the material will directly fall into the square hole 4, thereby achieving the effect of automatic discharging; when the push rod 18 is separated from the interference with the arc-shaped 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 the present embodiment, the material receiving mechanism includes a receiving hopper 38 in contact with the bottom of the conveying seat 1, and the receiving hopper 38 is used in correspondence with the square hole 4. The bottom of the receiving hopper 38 is integrally provided with a conveying pipe 37, and the outer wall of the conveying pipe 37 is annularly fixedly connected with a plurality of second connecting rods 36, and the other ends of the plurality of second connecting rods 36 are all fixedly connected to the inner side of the annular water receiving groove 33, and a second valve body 39 is installed on the conveying pipe 37. The second connecting rod 36 can stably install the conveying pipe 37 and the receiving hopper 38 on the annular water receiving groove 33, and the conveying seat 1 can be fitted and rotated on the top of the receiving hopper 38, so that the material discharged from the discharge port 23 falls into the receiving hopper 38 through the square hole 4, and finally is transported from the conveying pipe 37, and the opening and closing of the conveying 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 - Fig. 9As shown, the inner wall of the receiving hopper 38 is fixedly connected with a plurality of first connecting rods 32, and the top ends of the plurality of first connecting rods 32 are fixedly connected with the same arc plate 40, and the four baffle plates 25 are fixedly connected with the limiting rods 27 intermittently contacting with the arc plate 40 on the side close to the square hole 4. In order to improve the contact strength of the baffle plate 25 during the dehydration and extrusion process, the arc 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, as shown in FIG. 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 arc plate 40, so that the material can stably fall 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 at the same time, the limiting rod 27 always conflicts with the outer side surface of the arc plate 40. At this time, the push plate 19 is driven to move by the abutment rod 18. When the material is squeezed and dehydrated, the baffle plate 25 is restricted and will not rotate, so that the material can be better dehydrated. After extrusion and dehydration, the push plate 19 continues to move. At this time, the limiting rod 27 is disengaged from the conflict with the arc plate 40, and the rotation limit of the baffle plate 25 is released. Then, under the action of the extrusion force, the baffle plate 25 will be pushed to rotate, thereby achieving the effect of automatic discharging.

Those skilled in the art may make any selections according to their needs or convenience.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. 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 solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
