Description

Technical Field

[0001] This invention relates to the field of waste heat recovery technology, specifically to a waste heat recovery device for epoxy resin production. Background Technology

[0002] The production and processing of epoxy resins involves numerous heating and curing processes, making waste heat generation inevitable and resulting in significant energy loss. In traditional epoxy resin production processes, equipment such as reactors and curing ovens release substantial amounts of heat during operation. If this heat is not recovered and reused but instead released directly into the environment, it not only causes enormous energy waste but also leads to thermal pollution of the surrounding environment.

[0003] While existing waste heat recovery devices have some attempts to improve the technology, they are difficult to flexibly adjust the internal structure of the heat exchange tubes and cannot accurately control the contact area between the heat exchange tubes and the waste heat liquid. When faced with frequent changes in operating conditions during epoxy resin production, they cannot be flexibly adjusted. Therefore, it is necessary to propose a waste heat recovery device for epoxy resin production. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a waste heat recovery device for epoxy resin production.

[0005] The technical solution adopted by the present invention to solve its technical problem is: an epoxy resin production waste heat recovery device, including two support bases, a heat exchange component for waste heat recovery and a corresponding drive component. The heat exchange component includes a shell, and a gas supply pipe is rotatably connected through the shell and the two support bases. Several heat exchange tubes are embedded in the wall of the gas supply pipe. Fixing frames are fixedly installed at both ends inside the gas supply pipe. Several adjustment components for adjusting the amount of gas inlet are arranged in an array inside the gas supply pipe.

[0006] The adjustment assembly includes a first motor for driving the adjustment assembly, a lead screw rotatably connected to the outer wall of one of the fixed frames, a plurality of movable frames threadedly connected to the wall of the lead screw, an adjustment plate fixedly connected to the top corner of the outer wall of each of the movable frames, a plurality of adjustment holes of different diameters arrayed on each of the adjustment plates, and a flow guiding assembly for guiding airflow is provided inside the gas pipe.

[0007] The flow guiding assembly includes a first rotating rod rotatably connected to a fixed frame and several second rotating rods rotatably connected to the edge of the fixed frame. Several helical blades are fixedly connected to the walls of the several second rotating rods. A first transmission gear is fixedly connected to one end of the wall of the first rotating rod, and a third bevel gear is fixedly connected to one end of the wall of the first rotating rod. A driven gear is fixedly connected to one end of the wall of the several second rotating rods, and the several driven gears are threaded to the outer end of the first transmission gear.

[0008] Specifically, a first bevel gear is fixedly connected to one end of the lead screw wall, a second bevel gear is meshed with the first bevel gear, a first transmission rod is fixedly connected to the top of the second bevel gear, the first transmission rod is fixedly connected to the output end of the first motor, a number of adjusting plates are symmetrically fixedly connected to one end of their walls, a limiting block is opened on the inner wall of the gas supply pipe between the number of heat exchange tubes, the number of limiting blocks are locked in the limiting grooves, and the number of adjusting holes are vertically aligned with the heat exchange tubes.

[0009] Specifically, the lead screw is hollow inside, and the first rotating rod moves through the inside of the lead screw and is rotatably connected to the outer wall of another fixed frame. The lead screw wall is rotatably connected to a movable support rod near the third bevel gear, and the movable support rod is fixedly connected to the inner wall of the gas transmission pipe.

[0010] Specifically, a ring is fixedly connected to the upper end of the outer wall of one of the support seats, an inner bevel gear ring is fixedly connected to the edge of the inner ring wall, the inner bevel gear ring is meshed with a fourth bevel gear, a second transmission rod is fixedly connected to the lower end of the fourth bevel gear, and the second transmission rod is rotatably connected to the top end of the air supply pipe through a bearing, and a fifth bevel gear is fixedly connected to the bottom end of the second transmission rod, and the fifth bevel gear is meshed with a third bevel gear.

[0011] Specifically, the movable frame and the fixed frame are arranged in a triangular shape, and the ends of the movable frame and the fixed frame are arranged in a staggered manner.

[0012] Specifically, the drive assembly includes a second motor embedded inside one of the support seats.

[0014] The beneficial effects of this invention are:

[0015] (1) The epoxy resin production waste heat recovery device of the present invention can adjust the heat exchange tube flow port by adjusting the components. This can be achieved by adjusting the heat exchange tube with several different diameter adjustment holes, thereby changing the size of the gas flow inside the heat exchange tube and adjusting the contact area between the heat exchange tube and the waste heat liquid.

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] like Figures 1-7 As shown, the present invention provides the following technical solution:

[0029] Example 1: Waste heat recovery device for epoxy resin production, including two support bases 1, a heat exchange component for waste heat recovery and a corresponding drive component. The heat exchange component includes a shell 2, and a gas supply pipe 3 is rotatably connected through the shell 2 and the two support bases 1. Several heat exchange tubes 31 are embedded in the wall of the gas supply pipe 3. Fixing brackets 5 are fixedly installed at both ends inside the gas supply pipe 3. Several adjustment components for adjusting the amount of gas inlet are arranged in an array inside the gas supply pipe 3.

[0030] In use, epoxy resin processing raw material is first injected into the liquid inlet pipe at the upper end of the shell 2, and then gas is introduced into the gas delivery pipe 3. When the epoxy resin raw material comes into contact with several heat exchange tubes 31 through the inside of the shell 2, heat exchange can be carried out on the gas inside the gas delivery pipe 3. Finally, the epoxy resin raw material after heat exchange will be discharged from the liquid outlet pipe at the lower end of the shell 2.

[0031] Example 2: The technical solution of this example, which differs from Example 1, includes: an adjustment assembly comprising a lead screw 43, a movable frame 4, an adjustment plate 41, an adjustment hole 401, a limiting block 42, a limiting groove 301, a first bevel gear 44, a second bevel gear 45, a first transmission rod 46, a first motor 47, and a first motor 47 for driving the adjustment assembly. A lead screw 43 is rotatably connected to the outer wall of one of the fixed frames 5. Several movable frames 4 are threadedly connected to the wall of the lead screw 43. Adjustment plates 41 are fixedly connected to the top corners of the outer walls of each of the movable frames 4. Several adjustment holes 401 of different diameters are arrayed on each of the adjustment plates 41. A flow guiding assembly for guiding airflow is provided inside the air supply pipe 3. A first bevel gear 44 is fixedly connected to one end of the wall of the lead screw 43. Gear 44 is meshed with a second bevel gear 45. The top of the second bevel gear 45 is fixedly connected to a first transmission rod 46. The first transmission rod 46 is fixedly connected to the output end of the first motor 47. A number of adjusting plates 41 are symmetrically fixedly connected to one end of their plates. A number of limiting grooves 301 are opened on the inner wall of the gas pipe 3 between several heat exchange tubes 31. A number of limiting blocks 42 are locked in the limiting grooves 301. A number of adjusting holes 401 are vertically aligned with the heat exchange tubes 31. The screw 43 is hollow inside. The first rotating rod 51 moves through the inside of the screw 43 and is rotatably connected to the outer wall of another fixed frame 5. A movable support rod 48 is rotatably connected to the screw 43 near the third bevel gear 53. The movable support rod 48 is fixedly connected to the inner wall of the gas pipe 3.

[0032] In use, when it is necessary to adjust the contact area between the heat exchange tube 31 and the preheated liquid, the first motor 47 is started first, which drives the second bevel gear 45 to rotate through the first transmission rod 46. The second bevel gear 45 meshes with the first bevel gear 44, which drives the lead screw 43 to rotate. The lead screw 43 will drive multiple sets of moving frames 4 to move to one side. At this time, the adjusting plate 41 slides along the limiting groove 301 through several limiting blocks 42. At this time, the adjusting plate 41 corresponds to the flow port of the heat exchange tube 31 through several adjusting holes 401 of different diameters, thereby adjusting the amount of gas flow inside the heat exchange tube 31 and adjusting the contact area between the heat exchange tube 31 and the waste heat liquid.

[0033] Example 3: The technical solution of this example, which differs from Example 2, includes: a flow guiding assembly comprising a first rotating rod 51, a first transmission gear 52, a third bevel gear 53, a second rotating rod 54, and helical blades 56. The flow guiding assembly includes a first rotating rod 51 rotatably connected to a fixed frame 5, and several second rotating rods 54 rotatably connected to the edge of the fixed frame 5. Several helical blades 56 are fixedly connected to the walls of each of the second rotating rods 54. A first transmission gear 52 is fixedly connected to one end of the wall of each first rotating rod 51, and a third bevel gear 53 is fixedly connected to one end of the wall of each of the second rotating rods 54. Driven gears 55 are threadedly connected to the outer end of the first transmission gear 52. A ring 11 is fixedly connected to the upper end of the outer wall of one of the support bases 1. An inner bevel gear ring 12 is fixedly connected to the edge of the inner ring wall of the ring 11. The inner bevel gear ring 12 is meshed with a fourth bevel gear 65. The lower end of the fourth bevel gear 65 is fixedly connected to a second transmission rod 64. The second transmission rod 64 is rotatably connected to the top of the gas supply pipe 3 through a bearing. The bottom end of the second transmission rod 64 is fixedly connected to a fifth bevel gear 66. The fifth bevel gear 66 is meshed with a third bevel gear 53. The drive assembly includes a second motor 6 embedded in one of the support seats 1. The output end of the second motor 6 is fixedly connected to a third transmission rod 61. The third transmission rod 61 extends through the support seat 1 into the ring 11. One end of the rod wall of the third transmission rod 61 is fixedly connected to a second transmission gear 62. The second transmission gear 62 is meshed with a gear ring 63. The gear ring 63 is fixedly connected to the outer wall of the gas supply pipe 3.

[0034] In operation, the second motor 6 is first started, which drives the second transmission gear 62 via the third transmission rod 61. The second transmission gear 62 meshes with and drives the gear ring 63 to rotate. The gear ring 63 drives the gas delivery pipe 3 to rotate, which in turn drives the second transmission rod 64 to rotate. When the second transmission rod 64 rotates, it meshes with the inner bevel gear ring 12 via the fourth bevel gear 65, causing the second transmission rod 64 to rotate on its own axis while revolving around the sun. The rotation of the second transmission rod 64 drives the fifth bevel gear 66 to mesh with the third bevel gear 53. When the third bevel gear 53 rotates, it drives the first transmission gear 52 via the first rotating rod 51. The first transmission gear 52 meshes with and drives several driven gears 55 to rotate. The rotation of the driven gears 55 drives multiple sets of spiral blades 56 to rotate via the second rotating rod 54, thereby effectively transporting the gas inside the gas delivery pipe 3 and guiding the gas inside the gas delivery pipe 3 to maintain a relatively stable gas pressure.
