Description

Technical Field

[0001] This utility model relates to the technical field of crude benzene processing equipment, specifically a crude benzene dehydration device. Background Technology

[0002] Crude benzene is one of the products of crude coal gas generated from coal pyrolysis. It is a benzene series compound recovered from coke oven gas after ammonia removal, with benzene being the main component. Crude benzene is a pale yellow, transparent liquid, lighter than water, and insoluble in water. Crude benzene is mainly used for further processing to produce benzene, toluene, xylene, and other products, all of which are valuable basic organic chemical raw materials. Dehydration is a crucial step in the processing of crude benzene; it is usually necessary to remove moisture from the crude benzene to improve product quality and subsequent processing efficiency.

[0003] In existing technologies, such as the crude benzene dehydration device disclosed in utility model patent number 202323298564.1, a cam and sliding column are used to stir the crude benzene and anhydrous sodium sulfate while the lifting plate continuously tumbles the crude benzene, improving dehydration efficiency. However, this device still has some shortcomings in practical applications. First, its stirring method is relatively simple, and some anhydrous sodium sulfate accumulates at the bottom of the device, resulting in unsatisfactory dehydration. Second, in order to improve the dehydration effect, some devices are equipped with multiple sets of drive devices for multi-angle stirring. Although this improves the dehydration effect, it also increases the complexity of the equipment and manufacturing costs, and reduces the utilization rate of internal storage space. In addition, existing devices cannot effectively control the stirring depth and turbulence effect during the stirring process, so there is still room for improvement in dehydration efficiency.

[0004] To address the problems existing in the prior art, this utility model proposes a new technical solution for crude benzene dehydration device, which aims to further improve dehydration efficiency while simplifying the equipment structure and reducing manufacturing and maintenance costs.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0029] Example 1, please refer to Figures 1 to 4The present invention provides a technical solution: a crude benzene dehydration device, comprising a tank 1 and a stirring component, the stirring component comprising a driving component 4, a rotating cylinder 6, a U-shaped frame 11, and multiple turbulence components.

[0030] Tank 1 is used to hold crude benzene and anhydrous sodium sulfate, providing a place for the dehydration process. Drive unit 4 is used to drive the rotating drum 6 to rotate.

[0031] The driving component 4 is fixedly installed above the top wall of the tank body 1. The lower end of the rotating cylinder 6 is rotatably connected to the inner bottom wall of the tank body 1. The upper part of the rotating cylinder 6 penetrates the top wall of the tank body 1 and is rotatably connected to the top wall of the tank body 1. The driving component 4 is connected to the rotating cylinder 6 in a transmission manner, and the driving component 4 drives the rotating cylinder 6 to rotate.

[0032] The rotating cylinder 6 has a groove 8 extending through its side wall along the axial direction. The U-shaped frame 11 is slidably disposed in the groove 8 of the rotating cylinder 6, and a rack is fixedly installed on the inner side wall of the rotating cylinder 6. The various aerodynamic components are arranged longitudinally on the U-shaped frame 11.

[0033] The turbulence-inducing component includes a rotating shaft, a third gear 12, and two rotating plates 13. The third gear 12 is mounted on the outer wall of the middle part of the rotating shaft and the two are fixedly connected. The two ends of the rotating shaft pass through the U-shaped frame 11 laterally, and the two ends of the rotating shaft are rotatably connected to the U-shaped frame 11. The two ends of the rotating shaft are fixedly connected to the two rotating plates 13 respectively. The third gear 12 meshes with a rack. The stirring component also includes a linkage assembly, which is driven by the U-shaped frame 11. The linkage assembly drives the U-shaped frame 11 to slide up or down within the groove 8 of the rotating cylinder 6.

[0034] The rotating cylinder 6 has an axially extending groove 8 through its side wall for mounting a U-shaped frame 11. A rack is fixedly mounted on the inner side wall of the rotating cylinder 6, and the rack meshes with the third gear 12 of the turbulence-inducing assembly, driving the turbulence-inducing assembly to rotate. The U-shaped frame 11 is slidably disposed within the groove 8 of the rotating cylinder 6 for mounting the turbulence-inducing assembly. The U-shaped frame 11 can slide up and down within the groove 8 via a linkage assembly to adjust the stirring depth.

[0035] When the U-shaped frame 11 slides inside the rotating cylinder 6, it drives the third gear 12 to rise or fall. Since the third gear 12 meshes with the rack, it rotates when rising or falling. The third gear 12 drives the two rotating plates 13 to rotate through the rotating shaft, causing the rotating plates 13 to rotate on their own axis. The rotation of the rotating plates 13 stirs the liquid inside the tank 1. At the same time, the rotating cylinder 6 rotates (revolves) under the drive of the drive component 4. The rotating cylinder 6 drives each rotating plate 13 to revolve, which fully stirs and turbulents the liquid inside the tank 1. This allows the rotating plates 13 to generate a multi-directional turbulence effect during rotation, increasing the contact area between crude benzene and anhydrous sodium sulfate and improving the dehydration efficiency.

[0036] Specifically, a feed pipe 2 is fixedly installed on the top wall of the tank 1, and the feed pipe 2 is connected to the interior of the tank 1. A first electrically controlled valve is installed on the feed pipe 2. A discharge pipe 3 is fixedly installed on the bottom wall of the tank 1, and the discharge pipe 3 is connected to the interior of the tank 1. A filter screen is installed inside the outlet end of the discharge pipe 3, and a second electrically controlled valve is installed on the discharge pipe 3.

[0037] The feed pipe 2 is used to introduce crude benzene and anhydrous sodium sulfate into the tank 1, and the discharge pipe 3 is used to discharge the dehydrated crude benzene. A first electrically controlled valve is installed on the feed pipe 2 to control the opening and closing of the feed pipe 2. A second electrically controlled valve is installed on the discharge pipe 3 to control the opening and closing of the discharge pipe 3.

[0038] Specifically, a first gear 5 is fixedly mounted on the output shaft end of the drive component 4, and a second gear 7 is fitted on the outer wall of the upper end of the rotating cylinder 6, with the two fixedly connected. The first gear 5 meshes with the second gear 7. The drive component 4 may include, but is not limited to, a servo motor, a stepper motor, or the like.

[0039] When the drive unit 4 is started, the output shaft of the drive unit 4 drives the first gear 5 to rotate, the first gear 5 drives the second gear 7 meshing with it to rotate, and the second gear 7 drives the rotating cylinder 6 to rotate.

[0040] More specifically, the linkage component includes, but is not limited to, an electric telescopic rod 14, which is embedded in the upper part of the slide groove 8 of the detachable rotating cylinder 6, and the output shaft end of the electric telescopic rod 14 is fixedly installed with the upper end of the U-shaped frame 11.

[0041] The linkage components include, but are not limited to, an electric telescopic rod 14, and may also include a servo electric cylinder. In this embodiment, the linkage components are waterproofed, such as by laying an external waterproof layer. After the electric telescopic rod 14 is activated, its output shaft extends or retracts, driving the U-shaped frame 11 to descend or rise. The electric telescopic rod 14 is used to drive the U-shaped frame 11 to slide up and down within the chute 8, adjusting the stirring depth.

[0042] In operation, crude benzene, after preliminary dehydration, is first introduced into tank 1 through feed pipe 2, allowing it to come into contact with the anhydrous sodium sulfate stored inside tank 1. Then, the drive unit 4 is activated via a control switch. The output shaft of drive unit 4 drives the first gear 5 to rotate. The first gear 5, through meshing with the second gear 7, drives the rotating drum 6 to rotate. The rotation of the rotating drum 6 causes the various turbulence-inducing components to revolve, thus agitating the crude benzene and anhydrous sodium sulfate.

[0043] Simultaneously, the U-shaped frame 11 slides up and down within the rotating drum 6 via a linkage component, adjusting the stirring depth. The extension and retraction of the electric telescopic rod 14 directly drives the U-shaped frame 11 to move up and down. As the U-shaped frame 11 moves up and down, it pushes the third gear 12 to rotate, which in turn drives the rotating plate 13 to rotate (self-rotate). During the revolution, rotation, and up and down movement of each rotating plate 13, the crude benzene and anhydrous sodium sulfate are thoroughly stirred in multiple directions, improving the dehydration efficiency of the crude benzene.

[0044] During the dehydration process, anhydrous sodium sulfate absorbs the moisture in the crude benzene. The dehydrated crude benzene is discharged through the discharge pipe 3. The filter screen inside the discharge pipe 3 is used to filter out unreacted anhydrous sodium sulfate, ensuring that the discharged crude benzene is pure.

[0045] Example 2, please refer to Figures 5 to 6 The main difference between this embodiment and Embodiment 1 is that the linkage assembly also includes a pull rod 15, a fixing plate 16, a sliding plate 18, a reciprocating screw 19, a fourth gear 17, and a connecting plate 20. The fixing plate 16 is fixedly installed on the top wall of the tank 1. The fixing plate 16 is inverted L-shape. A rotating block is rotatably installed at the end of the fixing plate 16 away from the tank 1. The fourth gear 17 is fitted onto the lower outer wall of the rotating block, and the two are fixedly connected. The reciprocating screw 19 passes longitudinally through the rotating block, and the two are threadedly connected. The sliding plate 18 passes longitudinally through the fixing plate 16, and the two are slidably connected. The sliding plate 18, the reciprocating screw 19, and the pull rod 15 are arranged laterally and parallel to each other. The connecting plate 20 is fixedly connected to the upper ends of the sliding plate 18 and the reciprocating screw 19, and is rotatably connected to the upper end of the pull rod 15. The driving component 4 is connected to the fourth gear 17 for transmission.

[0046] In this configuration, the fourth gear 17 meshes with the second gear 7. After the drive unit 4 is activated, its output shaft drives the first gear 5 to rotate. The first gear 5 then drives the second gear 7, which meshes with it, to rotate. The second gear 7 then drives the fourth gear 17, which meshes with it, to rotate. The fourth gear 17 drives the rotating block to rotate, and the rotating block pushes the reciprocating screw 19 to move up and down repeatedly. During this reciprocating movement, the reciprocating screw 19 pushes the connecting plate 20 to move up and down repeatedly, and the connecting plate 20 drives the pull rod 15 to move up and down repeatedly. The pull rod 15 causes the U-shaped frame 11 to slide up and down, adjusting the stirring depth and further optimizing the stirring and turbulence effects.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
