Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, in particular to a rotary kiln device based on thermal analysis. Background Art

[0002] In the oil-based rock cuttings distillation process, indirect heating rotary kiln is a process commonly used in the industry. This process has certain requirements for the moisture content of the materials entering the rotary kiln, and the moisture content of the materials cannot be too high; materials with too high moisture content are more viscous, easy to agglomerate, and easy to stick to the wall, which can easily cause the rotary kiln to block the material; in addition, due to the high moisture content of the materials, the dispersion of the materials is poor, resulting in a significant decrease in the heat transfer capacity between the drum wall and the materials, affecting the performance of the equipment and reducing the working efficiency of the rotary kiln.

[0003] However, there is no device inside the rotary kiln in the prior art that can adjust the moisture content of the material. In view of the above situation, many factories have added a raw material pretreatment section. Through the pretreatment process, the material is mixed with dry and wet materials before entering the cylinder to adjust the moisture content of the material; however, this method requires a large amount of equipment and manpower, resulting in an increase in the company's fixed asset investment and operating costs. Summary of the invention

[0004] The object of the present invention is to provide a rotary kiln device based on thermal analysis to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: A rotary kiln device based on thermal analysis, comprising a cylinder, the cylinder is provided with an interlayer, straight-through pipes are evenly fixedly installed on the side of the cylinder, and the straight-through pipes are evenly distributed at the interlayer; a strengthening device is installed inside the straight-through pipe; and a shoveling plate group is evenly installed inside the cylinder. High-temperature steam is introduced into the straight-through pipe to heat up the interlayer, and the material in the cylinder is dried by heat conduction; the strengthening device strengthens the heat transfer in the straight-through pipe, which can achieve the purpose of efficient heat exchange and energy saving of the heat exchange equipment. The shoveling plate group scoops up the material to prevent the material from sticking and increase the gap between the materials, thereby indirectly increasing the drying rate.

[0006] According to the above technical solution, the port of the straight pipe located at the discharge end of the cylinder is fixedly connected with a rotary joint, the other end of the rotary joint is connected with a steam input pump through a pipeline, and the port of the straight pipe located at the feed end of the cylinder is connected with a steam trap through a pipeline. The steam input pump passes high-temperature steam into the straight pipe through the rotary joint, the temperature of the cylinder interlayer increases, the inner wall of the cylinder and the internal air become hot, and the material in contact with the inner wall of the cylinder can be heated and dried. The steam trap can guide out condensed water while preventing steam loss, reducing the influence of condensed water on the temperature of the interlayer. A gear ring is fixedly installed on the outside of the cylinder, and the external power mechanism rotates the cylinder by meshing the gear ring. The straight pipe introduces high-temperature steam from the discharge end of the cylinder, so that the inside of the cylinder presents a stepped temperature zone, in which the temperature closest to the discharge end is the highest and the temperature closest to the feed end is the lowest.

[0007] According to the above technical solution, the shoveling plate group includes a guide plate, an angled plate, a beveled plate, and a straight plate; one end of the guide plate is located at the feed end of the cylinder, and the other end of the guide plate is fixedly connected to the angled plate; the other end of the angled plate is fixedly connected to the beveled plate, and the end of the beveled plate away from the angled plate is fixedly connected to the straight plate; the connecting line between the guide plate, the angled plate, the beveled plate, and the straight plate is an inclined curve. The rotating cylinder drives the internal shoveling plate group to move, and the material enters the cylinder from the feed end of the cylinder. The guide plate guides it into the angled plate, and at the same time scoops up the material to spread it out. It is convenient for later drying. After the material reaches the angle plate, the rotating angle plate scoops up part of the material and dries it in the local space. As the angle plate tilts, the material falls from a high place, so that the material is fully in contact with the air for drying. At this time, the moisture on the surface of the material is dried and enters the angle plate. The angle plate scoops up the semi-dry material, so that the material is fully in contact with the air for drying. The moisture inside the material evaporates, and then the material reaches the straight plate, which scoops it up, so that the water vapor between the materials is quickly dissipated to prevent the material from getting wet again. At the same time, the straight plate guides the dried material to be discharged from the cylinder discharge port.

[0008] According to the above technical solution, the strengthening device includes a tube body and a plurality of wings, one end of each of the wings is hinged to the tube body, and the wings are staggered and evenly distributed on the side of the tube body. The tube body carries the wings into the straight-through tube; according to the field synergy analysis, the wings can increase the disturbance of the steam to the boundary layer, strengthen the heat transfer between the fluid in the core area and the fluid on the wall, thereby reducing energy consumption and improving the comprehensive heat exchange capacity.

[0009] According to the above technical solution, several control mechanisms are arranged inside the tube body, and the several control mechanisms are connected end to end to form a straight line; the control mechanism includes a support, a bracket, and a pillar, one end of the support and the pillar is fixedly connected to the tube body, and the other end of the support is fixedly connected to the bracket; the two ends of the bracket are respectively fixedly connected to the corresponding brackets of the two adjacent control mechanisms; the other end of the pillar is equipped with a gear through a bearing, and the end of the gear away from the pillar is fixedly connected to a rotating seat, the rotating seat is located on the side of the bracket away from the support, and the gear is located on the side of the bracket close to the support; the side of the support close to one end of the bracket is slidably connected with a rack, the teeth of the rack are meshed with the gear, and the side of the rack away from the support is slidably connected to the bracket. The gear is rotated by moving the rack, which drives the rotating seat to rotate, providing power for the control mechanism.

[0010] According to the above technical solution, a connecting seat is fixedly installed on the side of the bracket away from the support, and the side of the connecting seat away from the bracket is respectively hinged with support rod 1 and support rod 2; the end of the rotating seat away from the bracket is provided with slide groove 1 and slide groove 2, one end of the support rod 1 is slidably connected to slide groove 1 through a slide key, and one end of the support rod 2 is slidably connected to slide groove 2 through a slide key. The rotating seat rotates, driving slide groove 1 and slide groove 2 to move; thereby increasing or decreasing the angle between support rod 1 and support rod 2.

[0011] According to the above technical solution, the outer sides of the support rod 1 and the support rod 2 are respectively hinged with a push rod 1 and a push rod 2, and the end of the push rod 1 away from the support rod 1 passes through the tube body and is hinged with the wing, and the end of the push rod 2 away from the support rod 2 passes through the tube body and is hinged with another wing. The moving support rods 1 and 2 control the movement of the corresponding wing through the push rods 1 and 2, so that the angle between the corresponding wing and the tube body changes accordingly. The control mechanism controls the change of the angle between the wing and the tube body; when the angle between the wing and the tube body is about 10-20 degrees, the direction of the fluid velocity is roughly in the same direction as the axis, at this time, the heat transfer between the fluid in the core area and the fluid in the straight tube is weak, the flow resistance is small, and the steam flow rate is fast; when the angle between the wing and the tube body is about 20-30 degrees, the direction of the fluid velocity obviously deviates from the axis and deviates to the heat conduction direction, at this time, the heat transfer between the fluid in the core area and the fluid in the straight tube is strengthened, the flow resistance increases, and the steam flow rate slows down. Therefore, without reducing the steam flow rate per unit area of ​​the straight pipe, the steam flow rate can be adjusted in real time to cope with the situation of drying materials of different sizes or materials of different unit volumes.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0013] (1) By providing a lifting plate group, the rotating cylinder drives the internal lifting plate group to move, and the material enters the cylinder from the feeding end of the cylinder. The guide plate guides it into the angle plate and lifts up the material at the same time to spread the material apart. This is convenient for later drying. After the material reaches the angle plate, the rotating angle plate lifts up part of the material and dries it in a local space. As the angle plate tilts, the material falls from a high place, so that the material is fully in contact with the air for drying. At this time, the moisture on the surface of the material is dried and enters the angle plate. The angle plate lifts up the semi-dry material, so that the material is fully in contact with the air for drying. The moisture inside the material evaporates, and then the material reaches the straight plate. The straight plate lifts it up, so that the water vapor between the materials is quickly dispersed to prevent the material from getting wet again. At the same time, the straight plate guides the dried material out from the cylinder discharge port. This prevents material adhesion and increases the gap between materials, indirectly increasing the drying rate.

[0014] (2) By providing wings, several wings are staggered and evenly distributed on the side of the tube body. The tube body carries several wings into the straight tube; according to field synergy analysis, several wings can increase the disturbance of steam on the boundary layer, strengthen the heat transfer between the core area fluid and the wall fluid, thereby reducing energy consumption and improving the comprehensive heat exchange capacity;

[0015] (3) A control mechanism is provided to control the change of the angle between the wing and the tube body; when the angle between the wing and the tube body is about 10-20 degrees, the direction of the fluid velocity is roughly in the same direction as the axis, at which time the heat transfer between the fluid in the core area and the fluid in the straight tube is weak, the flow resistance is small, and the steam flow rate is fast; when the angle between the wing and the tube body is about 20-30 degrees, the direction of the fluid velocity obviously deviates from the axis and deviates to the heat conduction direction, at which time the heat transfer between the fluid in the core area and the fluid in the straight tube is enhanced, the flow resistance increases, and the steam flow rate slows down. In this way, the steam flow rate can be adjusted in real time without reducing the amount of steam per unit area of ​​the straight tube to cope with the situation of drying materials of different sizes or materials of different unit volumes.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

High-temperature steam is introduced into the straight pipe 11 to heat up the interlayer, and the material in the cylinder 1 is dried by heat conduction; the strengthening device strengthens the heat transfer in the straight pipe 11, which can achieve the purpose of efficient heat exchange and energy saving of the heat exchange equipment. The shoveling plate group scoops up the material to prevent the material from sticking and increase the gap between the materials, thereby indirectly increasing the drying rate.

[0029] The port of the straight pipe 11 at the discharge end of the cylinder 1 is fixedly connected to a rotary joint, and the other end of the rotary joint is connected to a steam input pump through a pipeline. The port of the straight pipe 11 at the feed end of the cylinder 1 is connected to a steam trap through a pipeline. The steam input pump passes high-temperature steam into the straight pipe 11 through the rotary joint, the temperature of the interlayer of the cylinder 1 increases, the inner wall of the cylinder 1 and the internal air become hot, and the material in contact with the inner wall of the cylinder 1 can be heated and dried. The steam trap can guide condensed water while preventing steam loss, reducing the influence of condensed water on the temperature of the interlayer. A gear ring is fixedly installed on the outside of the cylinder 1, and the external power mechanism rotates the cylinder 1 by meshing the gear ring. The straight pipe 11 introduces high-temperature steam from the discharge end of the cylinder 1, so that the inside of the cylinder 1 presents a stepped temperature area, where the temperature closest to the discharge end is the highest, and the temperature closest to the feed end is the lowest.

[0030] The lifting plate group includes a guide plate 21, an angled plate 22, an angled plate 23, and a straight plate 24; one end of the guide plate 21 is located at the feed end of the cylinder 1, and the other end of the guide plate 21 is fixedly connected to the angled plate 22; the other end of the angled plate 22 is fixedly connected to the angled plate 23, and the end of the angled plate 23 away from the angled plate 22 is fixedly connected to the straight plate 24; the connecting line between the guide plate 21, the angled plate 22, the angled plate 23, and the straight plate 24 is an inclined curve. The rotating cylinder 1 drives the internal lifting plate group to move, and the material enters the cylinder 1 from the feed end of the cylinder 1. The guide plate 21 guides it into the angled plate 22, and at the same time lifts the material to spread it out. It is convenient for later drying; after the material reaches the angled plate 22, the rotating angled plate 22 scoops up part of the material and dries it in the local space. As the angled plate 22 tilts, the material falls from a high place, thereby allowing the material to fully contact with the air for drying; at this time, the moisture on the surface of the material is dried and enters the angled plate 23. The angled plate 23 scoops up the semi-dry material, allowing the material to fully contact with the air for drying; the moisture inside the material is evaporated, and then the material reaches the straight plate 24, which scoops it up, allowing the water vapor between the materials to quickly dissipate to prevent the material from regaining moisture; at the same time, the straight plate 24 guides the dried material to be discharged from the discharge port of the cylinder 1.

[0031] The strengthening device includes a tube body 31 and a plurality of wings 32. One end of the plurality of wings 32 is hinged to the tube body 31. The plurality of wings 32 are staggered and evenly distributed on the side of the tube body 31. The tube body 31 carries the plurality of wings 32 into the straight tube 11. According to the field synergy analysis, the plurality of wings 32 can increase the disturbance of the steam to the boundary layer, strengthen the heat transfer between the fluid in the core area and the fluid on the wall, thereby reducing energy consumption and improving the comprehensive heat exchange capacity.

[0032] A plurality of control mechanisms 4 are arranged inside the tube body 31, and the plurality of control mechanisms 4 are connected end to end in a straight line; the control mechanism 4 comprises a support 41, a bracket 43, and a pillar 441, and one end of the support 41 and the pillar 441 is fixedly connected to the tube body 31, and the other end of the support 41 is fixedly connected to the bracket 43; the two ends of the bracket 43 are respectively fixedly connected to the corresponding brackets 43 of two adjacent control mechanisms 4; a gear 442 is installed on the other end of the pillar 441 through a bearing, and the end of the gear 442 away from the pillar 441 is fixedly connected to a rotating seat 45, and the rotating seat 45 is located on the side of the bracket 43 away from the support 41, and the gear 442 is located on the side of the bracket 43 close to the support 41; a rack 443 is slidably connected to the side of the support 41 close to one end of the bracket 43, and the teeth of the rack 443 are meshed with the gear 442, and the side of the rack 443 away from the support 41 is slidably connected to the bracket 43. The gear 442 is rotated by moving the rack 443 , thereby driving the rotating seat 45 to rotate, thereby providing power for the control mechanism 4 .

[0033] A connecting seat 463 is fixedly installed on one side of the bracket 43 away from the support 41, and a support rod 1 461 and a support rod 2 462 are respectively hinged on the side of the connecting seat 463 away from the bracket 43; a sliding groove 1 451 and a sliding groove 2 452 are opened on one end of the rotating seat 45 away from the bracket 43, and one end of the support rod 1 461 is slidably connected to the sliding groove 1 451 through a sliding key, and one end of the support rod 2 462 is slidably connected to the sliding groove 2 452 through a sliding key. The rotating seat 45 rotates, driving the sliding groove 1 451 and the sliding groove 2 452 to move; thereby increasing or decreasing the angle between the support rod 1 461 and the support rod 2 462.

[0034] The outer sides of the first support rod 461 and the second support rod 462 are respectively hinged with a push rod 1 321 and a push rod 2 322. The end of the push rod 1 321 away from the first support rod 461 passes through the tube body 31 and is hinged to the wing 32. The end of the push rod 2 322 away from the second support rod 462 passes through the tube body 31 and is hinged to the other wing 32. The moving support rod 1 461 and the second support rod 462 control the movement of the corresponding wing 32 through the push rod 1 321 and the push rod 2 322, so that the angle between the corresponding wing 32 and the tube body 31 changes accordingly. The control mechanism 4 controls the change of the angle between the wing 32 and the tube body 31; when the angle between the wing 32 and the tube body 31 is about 10-20 degrees, the direction of the fluid velocity is roughly in the same direction as the axis, at this time, the heat transfer between the fluid in the core area and the fluid in the straight tube 11 is weak, the flow resistance is small, and the steam flow rate is fast; when the angle between the wing 32 and the tube body 31 is about 20-30 degrees, the direction of the fluid velocity obviously deviates from the axis and deviates to the heat conduction direction, at this time, the heat transfer between the fluid in the core area and the fluid in the straight tube 11 is strengthened, the flow resistance increases, and the steam flow rate slows down. In this way, the steam flow rate is adjusted in real time without reducing the amount of steam per unit area of ​​the straight tube to cope with the situation of drying materials of different sizes or materials of different unit volumes.

[0035] Working principle: pull the rack 443 to rotate the gear 442, driving the rotating seat 45 to rotate clockwise; the chute 1 451 and the chute 2 452 reduce the angle between the support rod 1 461 and the support rod 2 462; the support rod 1 461 and the support rod 2 462 pull the corresponding support wing 32 to the tube body 31 through the push rod 1 321 and the push rod 2 322, so that the angle between the support wing 32 and the tube body 31 is about 10-20 degrees. The straight pipe 11 introduces high-temperature steam from the port at the discharge end of the cylinder 1, and the high-temperature steam quickly fills the inside of the straight pipe 11, and the inside of the cylinder 1 presents a stepped temperature area; then the material is introduced for drying.

[0036] When the material is large, it is not necessary to adjust the control mechanism 4. The rotating cylinder 1 drives the internal shoveling plate group to move, and the material enters the cylinder 1 from the feeding end of the cylinder 1. The guide plate 21 guides it into the angle plate 22, and at the same time shovels the material to spread the material. It is convenient for later drying; after the material reaches the angle plate 22, the rotating angle plate 22 shovels part of the material and dries it in the local space. As the angle plate 22 tilts, the material falls from a high place, so that the material is fully in contact with the air for drying; at this time, the moisture on the surface of the material is dried and enters the angle plate 23. The angle plate 23 shovels the semi-dry material so that the material is fully in contact with the air for drying; the moisture inside the material evaporates, and then the material reaches the straight plate 24, which shovels it so that the water vapor between the materials is quickly dispersed to prevent the material from getting wet; at the same time, the straight plate 24 guides the dried material to be discharged from the discharge port of the cylinder 1.

[0037] When the size of the material introduced is small, the rack 443 is pushed to rotate the gear 442, driving the rotating seat 45 to rotate counterclockwise; the chute 1 451 and the chute 2 452 increase the angle between the support rod 1 461 and the support rod 2 462; the support rod 1 461 and the support rod 2 462 pull the corresponding support wing 32 away from the tube body 31 through the push rod 1 321 and the push rod 2 322, so that the angle between the support wing 32 and the tube body 31 is about 20-30 degrees. The internal temperature of the cylinder 1 is increased, and the drying rate and effect are indirectly improved.
