Description

Technical Field

[0001] This utility model relates to the field of chemical waste treatment technology, specifically to a solvent fractionation structure for intermediate waste. Background Technology

[0002] In chemical production, the treatment of intermediate waste is a crucial step. Intermediate waste typically contains various solvents with different boiling points. To achieve resource recovery and reduce production costs, these solvents need to be fractionated and separated.

[0003] In traditional solvent fractionation processes for intermediate waste, fractionation is primarily achieved using fractionation towers. Specifically, the intermediate waste is introduced into the fractionation tower through the feed inlet, and then a heating device heats the material inside. As the temperature rises, solvent components with different boiling points vaporize sequentially and gradually rise. After the fractionation process is complete, the remaining waste is discharged from the waste outlet. From an operational convenience perspective, the internal structure of the fractionation tower is complex, and maintenance and cleaning require specialized personnel to enter the tower. Due to the limited space inside the tower, operation is difficult and requires significant time and manpower.

[0004] Therefore, it is necessary to provide an intermediate waste solvent fractionation structure to solve the above-mentioned technical problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A solvent fractionation structure for intermediate waste products, comprising: The fractionation tower body has a base at the bottom and a steam pipe at the top. A heating coil is fixedly installed at the bottom inside the fractionation tower body, and an auxiliary support base is fixedly installed on the lower side of one side of the outer surface of the fractionation tower body. The top of the auxiliary support base is fixedly installed with symmetrically distributed guide rails. An adjusting screw is rotatably installed between the two guide rails on the top of the auxiliary support base. A movable plate is sleeved on the outer wall of the adjusting screw, and a feeding mechanism is provided on the top of the movable plate. A first servo motor is fixedly installed on one side of the auxiliary support base, and the drive end of the first servo motor passes through the auxiliary support base and is fixedly connected to one end of the adjusting screw.

[0007] Preferably, the feeding mechanism includes a limiting frame, which is fixedly installed on the top of the movable plate. A rotating shaft is rotatably installed on the limiting frame. A sealing plate is fixedly installed at one end of the rotating shaft. A heating tank is fixedly installed on the inner surface of the sealing plate. A second servo motor is fixedly installed on the top of the limiting frame, and the drive end of the second servo motor is fixedly connected to the other end of the rotating shaft.

[0008] Preferably, a plurality of limiting blocks are fixedly installed at equal intervals and uniformly on the outer surface of the sealing plate, and an annular slide is provided on one side of the limiting frame, and the limiting blocks are slidably installed on the annular slide.

[0009] Preferably, the movable plate has a threaded hole adapted to the adjusting screw, and the movable plate is threadedly connected to the adjusting screw through the threaded hole.

[0010] Preferably, the bottom of the movable plate is provided with a groove corresponding to the position and number of guide rails, and the movable plate is slidably connected to the guide rails through the grooves on its bottom.

[0011] Preferably, the sealing plate is adapted to the installation opening, and a high-temperature resistant sealing gasket is provided at the connection between the sealing plate and the installation opening.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the coordinated use of a fractionation tower body, base, steam pipe, installation opening, auxiliary support seat, guide rail, adjusting screw, first servo motor, movable plate, second servo motor, rotating shaft, limit frame, sealing plate, heating tank, and heating coil, offers significant advantages over traditional fractionation towers used in intermediate waste solvent fractionation processes.

Furthermore, the heating tank of this equipment allows for easy access, facilitating the addition of waste materials and the cleaning of residues, making operation more convenient and significantly improving fractionation efficiency.

[0013] 2. This invention utilizes the combined use of an annular slide and a limiting block. When the heating tank rotates, the sealing plate rotates synchronously, causing the limiting block to slide within the annular slide. The limiting structure formed by the annular slide and the limiting block provides effective limiting support for the rotation of the heating tank, preventing single-point load-bearing on the rotating shaft. It distributes some of the weight and force to the annular slide, improving the operational stability of the heating tank, reducing uneven stress and wear on the rotating shaft, lowering the probability of equipment failure, and enhancing overall operational reliability.

[0017] Please see Figures 1-4 One embodiment provided by this utility model: A solvent fractionation structure for intermediate waste products, comprising: The fractionation tower body 1 has a base 2 at its bottom and a steam pipe 3 at its top. A heating coil 15 is fixedly installed at the bottom inside the fractionation tower body 1, and an auxiliary support seat 5 is fixedly installed on the lower side of one side of the outer surface of the fractionation tower body 1. The top of the auxiliary support base 5 is fixedly installed with symmetrically distributed guide rails 6. The top of the auxiliary support base 5 is rotatably installed between the two guide rails 6. The outer wall of the adjusting screw 7 is fitted with a movable plate 9. The top of the movable plate 9 is provided with a feeding mechanism. A first servo motor 8 is fixedly installed on one side of the auxiliary support base 5, and the drive end of the first servo motor 8 passes through the auxiliary support base 5 and is fixedly connected to one end of the adjusting screw 7.

[0018] The feeding mechanism includes a limiting frame 12, which is fixedly installed on the top of the movable plate 9. A rotating shaft 11 is rotatably installed on the limiting frame 12. A sealing plate 13 is fixedly installed on one end of the rotating shaft 11. A heating tank 14 is fixedly installed on the inner surface of the sealing plate 13. A second servo motor 10 is fixedly installed on the top of the limiting frame 12, and the drive end of the second servo motor 10 is fixedly connected to the other end of the rotating shaft 11. The feeding mechanism is designed to facilitate the entry and exit of the heating tank 14 into the fractionation tower 1. The second servo motor 10 drives the rotating shaft 11 to rotate the sealing plate 13 and the heating tank 14, which facilitates the dumping of waste materials.

[0019] In one embodiment, a plurality of limiting blocks 17 are fixedly installed at equal intervals and uniformly on the outer surface of the sealing plate 13. An annular slide 16 is provided on one side of the limiting frame 12, and the limiting blocks 17 are slidably installed on the annular slide 16 to provide limiting support for the rotation of the heating tank 14, distribute the weight, and improve the stability and reliability of operation.

[0020] In one preferred embodiment, the movable plate 9 has a threaded hole that matches the adjusting screw 7, and the movable plate 9 is threadedly connected to the adjusting screw 7 through the threaded hole, which can convert the rotation of the adjusting screw 7 into linear movement of the movable plate 9, so as to achieve precise and controllable displacement, and facilitate the entry and exit of the heating tank 14 into the fractionation tower 1.

[0021] In one embodiment, the bottom of the movable plate 9 is provided with a groove corresponding to the position and number of the guide rail 6, and the movable plate 9 is slidably connected to the guide rail 6 through the groove on its bottom, so as to ensure that the moving direction of the movable plate 9 is accurate and stable, and that the feeding structure and the heating tank 14 move smoothly, which is conducive to the orderly progress of the fractionation operation.

[0022] In one preferred embodiment, the sealing plate 13 is adapted to the mounting opening 4, and a high-temperature resistant sealing gasket is provided at the connection between the sealing plate 13 and the mounting opening 4, which can ensure the internal sealing of the fractionation tower body 1, prevent the leakage of high-temperature steam and solvent, ensure the fractionation effect, and improve safety.

[0023] The working principle of this utility model is as follows: All electrical components mentioned are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer for control, and existing publicly available power connection technologies are not elaborated here. Parts not mentioned in this device are the same as or can be implemented using existing technologies. During fractionation, the first servo motor 8 is first started, and its drive end drives the adjusting screw 7 to rotate. Based on the threaded transmission principle between the adjusting screw 7 and the movable plate 9, and the sliding fit between the movable plate 9 and the guide rail 6, the movable plate 9 can move stably along the direction of the guide rail 6. As the movable plate 9 moves, the feeding mechanism at its top moves accordingly, thereby causing the heating tank 14 to move out of the fractionation tower 1 through the installation opening 4. At this time, the operator can add intermediate waste material into the heating tank 14. After the waste material is added, the first servo motor 8 is driven again to reset the heating tank 14 back into the fractionation tower 1. Simultaneously, the sealing plate 13 closes the installation opening 4 to ensure a relatively sealed environment inside the fractionation tower 1. Subsequently, the heating coil 15 is activated to heat the waste material inside the heating tank 14. As the temperature rises, solvents with different boiling points reach their boiling points sequentially according to their boiling point characteristics and gradually vaporize and rise. The vaporized solvent vapor enters the external condenser through the steam pipe 3, where it exchanges heat with the coolant and is cooled into a liquid. After the fractionation process is completed, the first servo motor 8 is controlled again to remove the heating tank 14 from inside the fractionation tower 1. Next, the second servo motor 10 is activated, and its drive end drives the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 is transmitted to the heating tank 14 through the sealing plate 13, causing the heating tank 14 to rotate 180 degrees around the shaft, thereby emptying the waste material inside. To facilitate waste collection, a container can be placed under the heating tank 14 in advance. After the waste is cleaned up, the heating tank 14 is controlled to reset, and new intermediate waste material can be added to start the next round of fractionation operation.

[0024] During the rotation of the heating tank 14, the sealing plate 13 rotates synchronously with the heating tank 14. This movement causes the limiting block 17, installed at a specific position on the sealing plate 13, to slide on the annular slide rail 16. The limiting structure formed by the annular slide rail 16 and the limiting block 17 provides effective limiting support for the rotation of the heating tank 14. This limiting support mechanism avoids relying solely on the rotating shaft 11 to bear the entire weight of the heating tank 14. Through the interaction between the annular slide rail 16 and the limiting block 17, part of the weight of the heating tank 14 and the force generated during rotation are distributed to the annular slide rail 16, thereby significantly improving the stability of the heating tank 14 during operation. From the perspective of overall equipment performance, this design effectively reduces problems such as uneven stress on the rotating shaft 11 and accelerated wear that may be caused by single-point support, reduces the probability of equipment failure, and thus improves the stability and reliability of the entire equipment operation.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
