Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, in particular to equipment for rapidly and evenly drying refractory materials. Background Art

[0002] Drying is the process of using heat energy to vaporize the moisture in wet materials, and using airflow or vacuum to carry away the vaporized moisture, thereby obtaining dry materials. When refractory materials are produced, they are generally required to be dried to remove internal moisture, thereby ensuring that the storage process of the refractory materials after production is stable, not prone to failure, and prolonging their lifespan, thereby ensuring the subsequent use of the refractory materials.

[0003] The refractory material drying equipment in the prior art usually adopts box-type hot air drying. During the drying process, the refractory material is gradually dried on the shelves inside the box. Since the refractory material is stationary, the refractory material that is laid flat and stacked together is easily fitted with each other and with the shelves, and is therefore not convenient for direct contact with the hot air flow. On the one hand, the drying is not uniform and the heat utilization rate is low. On the other hand, the drying is not fast enough. When drying a large number of refractory materials, multiple groups of shelves are required for multiple drying operations, which is time-consuming and labor-intensive. Unevenly dried materials also need to be gathered together for secondary or multiple drying operations. The degree of automation is low, and the demand for fast and uniform drying of large quantities of refractory materials cannot be met. In view of the deficiencies in the prior art, the present invention provides a device for fast and uniform drying of refractory materials to solve the above problems. Summary of the invention

At the same time, under the rotating drying action of the drying box and the drying roller, the refractory materials are continuously tumbled during the drying process and are in full contact with the hot air flow without dead angles, thereby ensuring that the surface of the refractory materials is evenly dried. At the same time, when refractory materials of different models and humidity are incompletely dried during the drying process, the return material device is designed to facilitate rapid return material multi-stage drying, simplify the secondary drying operation of the refractory materials, and ensure that the equipment saves time and effort during the drying process of the refractory materials, thereby meeting the needs of rapid and uniform drying processing of large quantities of refractory materials.

[0025] 1. The equipment for fast and uniform drying of refractory materials has automatic loading and unloading control during the drying process of refractory materials, and has strong automation capability, which is convenient for realizing large-scale rapid drying operations. At the same time, under the rotating drying action of the drying box and the drying roller, the refractory materials are constantly tumbling during the drying process, and are fully in contact with the hot air flow without dead angles, ensuring that the surface of the refractory materials is evenly dried.

The hot air flow enters the drying box through the first connecting pipe for preliminary drying. At the same time, after passing through the drying box, it enters the lifting box through the second connecting pipe to preheat and secondary dry the material being lifted in the lifting box. On the one hand, it increases the energy utilization rate, and on the other hand, it ensures that multi-stage preheating and drying operations are performed during the return drying of refractory materials that have undergone multi-stage drying, thereby avoiding the problem that the refractory materials are cooled during the transportation of the conveying box and slowly heated up in the drying box during the return process, thereby further ensuring the drying effect of the materials.

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] The embodiments of the present application solve the problem of refractory material drying equipment in the prior art by providing a device for quickly and evenly drying refractory materials. The device usually adopts box-type hot air drying. During the drying process, it is not convenient for the refractory materials to be directly in contact with the hot air flow at various positions. On the one hand, the drying is not uniform and the heat utilization rate is low. On the other hand, the drying is not fast enough. When drying large quantities of refractory materials, multiple groups of shelves are required for multiple drying operations, which is time-consuming and labor-intensive. Materials that are dried unevenly need to be gathered together for a second or multiple drying operations. The degree of automation is low, and the demand for fast and uniform drying of large quantities of refractory materials cannot be met.

[0042] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] The embodiment of the present invention discloses a device for quickly and evenly drying refractory materials.

[0044] A material return device 70 is provided at the bottom of the drying box 30. The material return device 70 includes a material return hopper 701 and a conveying box 702 provided at the bottom of the drying box 30. A second spiral plate 7021 and a second transmission unit 5 for driving the second spiral plate 7021 are provided inside the conveying box 702.

[0045] A driving unit 4 for providing power to the first transmission unit 3 and the second transmission unit 5 is provided on the feeding pipe 2 .

[0046] The feeding device 40 comprises:

[0047] A hopper 401 is disposed on the drying box 30 and is connected to the feed pipe 2;

[0048] A ground bucket 402, which is disposed on the equipment base 10;

[0049] A lifting box 403 is provided between the ground bucket 402 and the material bucket 401. A conveying unit 7 for lifting materials is provided inside the feeding device 40;

[0050] The loading device 40 provided in the equipment has a compact structure and is easy to operate. The ground bucket 402 in the loading device 40 is the initial loading position. When the material is placed inside the ground bucket 402, the material can be transported through the lifting box 403 and the conveying unit 7. When the material is transported to the position of the hopper 401, the material can be sent to the feed pipe 2 through the hopper 401, and the material enters the drying box 30 and the drying roller 1 through the feed pipe 2.

[0051] The conveying unit 7 includes a second motor 71 arranged on the side of the lifting box 403 and a third pulley 72 connected to the output end of the second motor 71. The bottom of the lifting box 403 is rotatably connected to a fourth pulley 73. The fourth pulley 73 and the third pulley 72 are sleeved with a conveyor belt 74.

[0052] The conveying unit 7 has a compact structure and stable operation. When the conveying unit 7 is working, it is driven by the second motor 71. The second motor 71 drives the third pulley 72 to rotate, and the third pulley 72 drives the conveyor belt 74 and the fourth pulley 73 to rotate. When the conveyor belt 74 rotates, the material plate on its surface lifts and transports the material. When it is lifted to the highest position, it falls and enters the hopper 401 through the opening at the upper end of the lifting box 403.

[0053] The pipeline device 60 comprises:

[0054] A first connecting pipe 601, which is disposed between the heat source device 20 and the drying box 30;

[0055] A second connecting pipe 602, which is disposed between the drying box 30 and the lifting box 403;

[0056] A third connecting pipe 603, which is disposed between the lifting box 403 and the condensing device 50;

[0057] The equipment realizes the guidance of hot air flow through the design of the first connecting pipe 601, the second connecting pipe 602 and the third connecting pipe 603. The hot air flow enters the drying box 30 through the first connecting pipe 601 for preliminary drying. At the same time, after passing through the drying box 30, it enters the lifting box 403 through the second connecting pipe 602 to preheat and secondary dry the material being lifted in the lifting box 403. On the one hand, it increases the energy utilization rate, and on the other hand, it ensures that multi-stage preheating and drying operations are performed during the return drying of refractory materials that are undergoing multi-stage drying, thereby avoiding the problem of cooling of the refractory materials during transportation in the conveying box 702 and slow heating in the drying box 30 during the return process, and further ensuring the drying effect of the materials.

[0058] The drying roller 1 comprises a rotating part 11 rotatably connected to the inside of the drying box 30 and a net cylinder 12 fixedly connected to the rotating part 11, and a toggling rib 13 is fixedly connected to the inside of the net cylinder 12;

[0059] The drying roller 1 provided in the equipment has a simple structure. The design of the rotating part 11 makes it easy for the drying roller 1 to rotate inside the drying box 30. The design of the mesh tube 12 makes it easy for the hot air flow to enter the inner cavity of the mesh tube 12 through the gaps in the mesh tube 12, thereby drying the refractory material. The design of the stirring ribs 13 makes it possible for the mesh tube 12 to drive the stirring ribs 13 to rotate during the rotation process, and the stirring ribs 13 are used to continuously flip the refractory material, thereby ensuring that the refractory material is continuously tumbled and fully contacted with the hot air flow.

[0060] The driving unit 4 includes a limit seat 41 arranged on the feed pipe 2 and a first motor 42 fixedly connected to the limit seat 41. The driving unit 4 in the device has a simple structure. The limit seat 41 is used to provide power to the first motor 42, and the first motor 42 is used to provide power to the first transmission unit 3 and the second transmission unit 5.

[0061] The first transmission unit 3 includes a first drive shaft 31 rotatably connected to the inside of the feed pipe 2, the first drive shaft 31 is connected to the output end of the first motor 42, the first drive shaft 31 is connected to a connecting rod 32, the connecting rod 32 is connected to a rotating drum 33, the rotating drum 33 is connected to a first rack 34, the inside of the rotating part 11 is connected to a second rack 35, and the second rack 35 is meshed with the first rack 34;

[0062] The first transmission unit 3 has a simple structure and stable operation. When it is necessary to drive the drying roller 1 to rotate, the first motor 42 is used to provide power. The first motor 42 drives the first drive shaft 31 to rotate, the first drive shaft 31 drives the connecting rod 32 to rotate, the connecting rod 32 drives the rotating drum 33 to rotate, the rotating drum 33 drives the first rack 34 to rotate, the first rack 34 drives the second rack 35 to rotate, and then drives the rotating part 11 to rotate through the second rack 35, so that the rotating part 11 drives the drying roller 1 to rotate.

[0063] The second transmission unit 5 includes a second driving shaft 51 connected to the central axis position of the second spiral plate 7021 and a first pulley 52 fixedly connected to the second driving shaft 51, a second pulley 54 is provided on the first driving shaft 31, and a belt 53 is sleeved between the second pulley 54 and the first pulley 52. ​​When the first motor 42 drives the first driving shaft 31 to rotate, the first driving shaft 31 drives the second pulley 54 to rotate, the second pulley 54 drives the belt 53 to rotate, the belt 53 drives the first pulley 52 to rotate, the first pulley 52 drives the second driving shaft 51 to rotate, and the second driving shaft 51 drives the second spiral plate 7021 to rotate, so that the second spiral plate 7021 is used to transport the refractory materials that are returned from the return hopper 701 and the conveying box 702 and need to be dried for the second time, and finally transport them to the position of the loading device 40 for the secondary drying operation.

[0064] A power cut-off unit 6 is provided between the first transmission unit 3 and the second transmission unit 5. The transmission box 702 is slidably connected to the bottom of the drying box 30. A bracket 7031 is connected to the bottom of the transmission box 702. An electric push rod 7032 is connected to the bracket 7031. The output end of the electric push rod 7032 is connected to the side wall of the transmission box 702.

[0065] The transmission box 702 is connected to an overhead frame 7022, and the power cut-off unit 6 includes a clamping shaft 64 fixedly connected to the first drive shaft 31 and a connecting frame 61 fixedly connected to the overhead frame 7022. The connecting frame 61 is slidably connected to the limit seat 41 and is fixedly connected to a shaft seat 62. The shaft seat 62 is used to support the second pulley 54. The second pulley 54 is provided with a clamping hole 63 that is engaged with the clamping shaft 64.

[0066] The device is designed with a power cut-off unit 6, so that when the return device 70 moves to the secondary recovery refractory material and performs secondary drying, the second transmission unit 5 is automatically connected to the output end position of the driving unit 4, so that the second spiral plate 7021 inside the return device 70 at this position automatically rotates to feed the material, and feeds the material to the feeding device 40 for secondary feeding and drying. When the return device 70 returns to the initial position, the second transmission unit 5 is automatically disconnected from the output end position of the driving unit 4, and the second spiral plate 7021 inside the return device 70 at this position automatically stops rotating, thereby reducing energy consumption;

[0067] The position of the conveying box 702 is adjusted by the electric push rod 7032. When the electric push rod 7032 drives the conveying box 702 to move, the conveying box 702 drives the connecting frame 61 to move, the connecting frame 61 drives the shaft seat 62 to move, and the shaft seat 62 drives the second pulley 54 to move. When the clamping hole 63 of the second pulley 54 is engaged with the clamping shaft 64, the second transmission unit 5 is in operation, and the power of the first motor 42 can be transmitted to the second drive shaft 51. When the clamping hole 63 of the second pulley 54 is disengaged from the clamping shaft 64, the second pulley 54 is stationary, so that the second transmission unit 5 is stationary and the second drive shaft 51 cuts off power. Therefore, when the return device 70 is not in use, the second spiral plate 7021 in the return device 70 is stationary.

[0068] A finished product hopper 101 is provided on the equipment base 10, and an intermediate hopper 4031 is provided on the lifting box 403. The finished product hopper 101 is located at the unloading port of the drying box 30, and the intermediate hopper 4031 is located at the unloading port of the conveying box 702. The first driving shaft 31 is connected with a first spiral plate 21, and the first spiral plate 21 is located inside the feed pipe 2. The equipment is designed with a finished product hopper 101 to facilitate the collection of dried qualified refractory materials. The design of the intermediate hopper 4031 facilitates the return of materials recovered by the return device 70 for the second time, so that the returned materials directly enter the lifting box 403. The design of the first spiral plate 21 allows the refractory materials to be thrusted by the first spiral plate 21 when entering the feed pipe 2 from the hopper 401, so that they are not easily blocked and the feeding is uniform.

[0069] The equipment for quickly and evenly drying refractory materials, during use, firstly loads the refractory materials to be dried into the interior of the drying box 30 through the loading device 40, and during operation, the refractory materials are placed in the ground bucket 402, and the refractory materials are transported to the hopper 401 through the design of the lifting box 403 and the conveying unit 7, and then enter the interior of the feed pipe 2 through the hopper 401, and then enter the drying roller 1 inside the drying box 30 through the feed pipe 2;

[0070] The driving unit 4 drives the drying roller 1 to rotate through the first transmission unit 3, thereby driving the refractory material to rotate continuously;

[0071] At the same time, the heat source device 20 emits heat and transmits it to the inside of the drying box 30 through the first connecting pipe 601, thereby drying the refractory material that is constantly rolling inside the drying roller 1. The refractory material itself is constantly rolling and changing position and has a large contact area with the heat source airflow, thereby ensuring uniform and rapid drying.

[0072] The heat source airflow simultaneously passes through the second connecting pipe 602 and enters the interior of the lifting box 403, and preheats and performs secondary drying operations on the refractory materials lifted in the lifting box 403, so as to ensure more efficient energy utilization and improve the material drying effect. Finally, the hot airflow in the lifting box 403 passes through the third connecting pipe 603 and enters the interior of the condensing device 50, and is condensed and cooled by the evaporator in the condensing device 50 and the waste heat is recovered by the waste heat recovery device in the condensing device 50, so as to improve the energy utilization rate of the equipment.

[0073] After the refractory material is dried inside the drying roller 1, it falls into the inner cavity of the drying box 30 and slides downward by gravity, and finally slides downward from the discharge port of the drying box 30;

[0074] If the refractory material is completely dried, the finished product hopper 101 can be used to receive it directly;

[0075] If the refractory material is not completely dried, at this time, the electric push rod 7032 is used to drive the conveying box 702 to move, so that the conveying box 702 drives the return hopper 701 to move to the discharge port position of the drying box 30, and the refractory material enters the conveying box 702, and drives the second transmission unit 5 to move through the driving unit 4, and the second transmission unit 5 is used to drive the second spiral plate 7021 to rotate, so as to transport the refractory material. Finally, the refractory material is discharged from the discharge position of the conveying box 702, falls into the middle bucket 4031 after being discharged, and enters the interior of the lifting box 403, and enters the interior of the drying box 30 again through the conveying unit 7 for cyclic drying, thereby ensuring a good drying effect and the drying process can be quickly switched according to actual conditions.
