Description

Technical Field

[0001] This utility model relates to the field of chemical reactor technology, and in particular to a chemical reactor with vibration reduction and noise reduction functions. Background Technology

[0002] In chemical production processes, chemical reactors, as core equipment, are widely used in various process steps such as material mixing, reaction, and heat transfer. However, traditional chemical reactors generate strong vibrations during operation due to the operation of their stirring structures. This vibration not only damages the equipment's structure and shortens its service life, but also propagates through media such as the ground, causing resonance in surrounding equipment and affecting the overall stability of equipment operation in the production workshop. Furthermore, the vibration generates significant noise, seriously endangering the health of operators, increasing occupational health risks, and failing to meet environmental protection requirements. Therefore, we have introduced a chemical reactor with vibration reduction and noise reduction functions. Utility Model Content

[0003] The main purpose of this invention is to provide a chemical reactor with shock absorption and noise reduction functions, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A chemical reactor with vibration and noise reduction functions includes a fixed ring. Three support rods are fixedly connected to the outer surface of the fixed ring, and vibration and noise reduction structures are fixedly connected to the lower ends of the three support rods. A chemical reactor body is fixedly sleeved inside the fixed ring. A first mounting plate and a second mounting plate are fixedly connected to the outer surface of the chemical reactor body, with the first mounting plate located below the second mounting plate. A control mechanism is fixedly installed on the upper end of the first mounting plate. A feed pipe is inserted and fixedly connected to the front part of the upper end of the fixed ring, and a discharge pipe is inserted and fixedly connected to the right part of the lower end of the fixed ring. A switch valve is movably installed on the outer surface of the discharge pipe.

[0005] Preferably, the vibration damping and noise reduction structure includes a fixing block, with four through fixing holes at the upper corners of the fixing block. A mounting cylinder is fixedly connected to the middle of the upper end of the fixing block. A damper and a spring are fixedly connected to the lower inner wall of the mounting cylinder. A top block is fixedly connected to the upper end of the damper and the upper end of the spring. The upper end of the top block is fixedly connected to the lower end of the corresponding support rod.

[0006] By adopting the above technical solution, the vibration generated during the operation of the chemical reactor can be effectively absorbed and buffered by the combination of dampers and springs, thereby reducing the vibration amplitude and noise, extending the service life of the equipment, and improving the working environment.

[0007] Preferably, the damper is located inside the spring and has a gap with the inner wall of the spring, and the spring has a gap with the inner wall of the mounting cylinder.

[0008] By adopting the above technical solutions, we can avoid hard collisions between dampers and springs during operation, reduce additional noise, ensure vibration and noise reduction effects, and guarantee the long-term stable operation of the structure.

[0009] Preferably, the control mechanism includes a servo motor, an L-shaped plate, and a driven gear. The output end of the servo motor is fixedly mounted with a driving gear. The outer surfaces of the driving gear and the driven gear are meshed with a toothed transmission belt. The lower end of the driven gear is fixedly connected to a stirring assembly. The lower end of the servo motor is fixedly connected to the upper end of the first mounting plate. The upper end of the servo motor is fixedly connected to the lower end of the second mounting plate, and the output end of the servo motor passes through the lower end of the second mounting plate and extends onto the second mounting plate. The lower end of the L-shaped plate is fixedly connected to the upper end of the fixing ring.

[0010] By adopting the above technical solution, a stable power transmission system is formed by a servo motor, a drive gear, a driven gear, and a toothed transmission belt, which provides power to the stirring component.

[0011] Preferably, the upper ends of both the driving gear and the driven gear are movably connected to the upper inner wall of the L-shaped plate via bearings.

[0012] By adopting the above technical solution, stable support is provided for the driving gear and driven gear, ensuring smooth power transmission, reducing shaking and energy loss during transmission, and improving the working efficiency of the control mechanism.

[0013] Preferably, the stirring assembly includes a movable rod, a rotating rod is fixedly connected to the lower end of the movable rod, two L-shaped stirring blades are fixedly connected to the lower part of the outer surface of the rotating rod, several stirring rods are fixedly connected to the right ends of the two L-shaped stirring blades near the center of the rotating rod, and the ends of the several stirring rods near the center of the rotating rod are fixedly connected to the outer surface of the rotating rod, and the upper end of the movable rod is fixedly connected to the lower end of the driven gear.

[0014] By adopting the above technical solution, the moving rod, rotating rod, L-shaped stirring blade and stirring rod work together to increase the stirring range and intensity, making the materials more uniformly mixed, and improving the fullness of chemical reaction and production efficiency.

[0015] Preferably, the upper end of the movable rod is movably connected to the upper inner wall of the chemical reactor body through a bearing, and the lower end of the rotating rod is movably connected to the lower inner wall of the chemical reactor body through a rotating shaft.

[0016] By adopting the above technical solutions, we can ensure that the stirring components rotate flexibly and stably, reduce friction and resistance during the rotation process, reduce equipment wear, and extend the service life of the stirring components.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, when the stirring component inside the chemical reactor starts to stir the material, the vibration generated is transmitted to the top block of the vibration damping and noise reduction structure through the support rod, triggering the vibration damping and noise reduction structure to work. The top block transmits the vibration energy to the damper and spring inside the mounting cylinder below. The damper inside the spring uses the internal fluid damping characteristics to preferentially absorb part of the vibration energy and convert it into heat energy for release, thus weakening the vibration intensity. After the damper absorbs part of the energy, the spring undergoes elastic deformation due to the remaining vibration energy, and uses its own elasticity to further buffer the vibration. Through the synergistic effect of the damper and the spring, the vibration intensity transmitted to the fixed block is greatly reduced, the propagation of vibration to the ground and the vibration amplitude of the chemical reactor body are reduced, the noise generated by vibration is effectively suppressed, and the chemical reactor body is ensured to operate continuously in a quiet and stable state, extending the service life of the equipment and improving the production environment. 2. In this utility model, when the servo motor power is turned on, the servo motor starts to run, and its output end drives the fixedly installed drive gear to rotate. When the drive gear rotates, it transmits power to the toothed transmission belt through meshing, causing it to start moving. The moving toothed transmission belt then meshes with the driven gear, driving the driven gear to rotate synchronously. After the driven gear rotates, the rotating rod fixedly connected to the lower end of the movable rod rotates accordingly. Two L-shaped stirring blades and several stirring rods fixedly connected to the lower part of the outer surface of the rotating rod rotate with the rotating rod, stirring the materials in the chemical reactor body, realizing rapid and uniform stirring, effectively improving the fullness of material mixing, ensuring that the chemical reaction proceeds fully, and improving product quality and production efficiency.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figure 1-4 This utility model provides a technical solution: A chemical reactor with vibration and noise reduction function includes a fixed ring 1. Three support rods 2 are fixedly connected to the outer surface of the fixed ring 1. Vibration and noise reduction structures 3 are fixedly connected to the lower ends of the three support rods 2. A chemical reactor body 4 is fixedly sleeved inside the fixed ring 1. A first mounting plate 5 and a second mounting plate 6 are fixedly connected to the outer surface of the chemical reactor body 4, and the first mounting plate 5 is located below the second mounting plate 6. A control mechanism 7 is fixedly installed on the upper end of the first mounting plate 5. A feed pipe 8 is inserted and fixedly connected to the front part of the upper end of the fixed ring 1. A discharge pipe 9 is inserted and fixedly connected to the right part of the lower end of the fixed ring 1. A switch valve 10 is movably installed on the outer surface of the discharge pipe 9.

[0024] In this embodiment, the vibration damping and noise reduction structure 3 includes a fixing block 31. Each of the four corners of the upper end of the fixing block 31 has a through fixing hole 32. The middle of the upper end of the fixing block 31 is fixedly connected to the mounting cylinder 33. The lower inner wall of the mounting cylinder 33 is fixedly connected to a damper 34 and a spring 35. The upper end of the damper 34 and the upper end of the spring 35 are jointly fixedly connected to a top block 36. The upper end of the top block 36 is fixedly connected to the lower end of the corresponding support rod 2. The damper 34 is located inside the spring 35 and there is a gap between it and the inner wall of the spring 35. There is also a gap between the spring 35 and the inner wall of the mounting cylinder 33.

[0025] Through the above scheme: using bolts to fix the fixing holes 32 at the four corners of the upper end of the fixing block 31, the three fixing blocks 31 are firmly installed on the ground, providing a stable foundation for the chemical reactor body 4. When the stirring component 76 inside the chemical reactor body 4 starts to operate and stir the material, the generated vibration is transmitted through the support rod 2 to the top block 36 of the vibration damping and noise reduction structure 3, triggering the vibration damping and noise reduction structure 3 to work. The top block 36 transmits the vibration energy to the damper 34 and spring 35 inside the mounting cylinder 33 below. The damper 34, located inside the spring 35, utilizes the internal fluid damping characteristics to preferentially absorb part of the vibration energy and convert it into heat energy for release, thus reducing vibration. In the case of weak vibration intensity, after the damper 34 absorbs part of the energy, the spring 35 undergoes elastic deformation due to the remaining vibration energy, and further buffers the vibration using its own elasticity. Since there is a gap between the spring 35 and the inner wall of the mounting cylinder 33, the spring 35 will not make a hard collision with the inner wall of the mounting cylinder 33 during the deformation process, thus avoiding the generation of additional noise. Through the synergistic effect of the damper 34 and the spring 35, the vibration intensity transmitted to the fixed block 31 is greatly reduced, the vibration propagation to the ground and the vibration amplitude of the chemical reactor body 4 are reduced, and the noise generated by the vibration is effectively suppressed, ensuring that the chemical reactor body 4 continues to operate in a quiet and stable state.

[0026] In this embodiment, the control mechanism 7 includes a servo motor 71, an L-shaped plate 72, and a driven gear 73. A drive gear 74 is fixedly mounted on the output end of the servo motor 71. A toothed drive belt 75 meshes with the outer surfaces of the drive gear 74 and the driven gear 73. A stirring assembly 76 is fixedly connected to the lower end of the driven gear 73. The lower end of the servo motor 71 is fixedly connected to the upper end of the first mounting plate 5, and the upper end of the servo motor 71 is fixedly connected to the lower end of the second mounting plate 6. The output end of the servo motor 71 passes through the lower end of the second mounting plate 6 and extends onto the second mounting plate 6. The lower end of the L-shaped plate 72 is fixedly connected to the upper end of the fixing ring 1. The upper ends of both the drive gear 74 and the driven gear 73 are connected by bearings. The stirring assembly 76 is movably connected to the upper inner wall of the L-shaped plate 72; the stirring assembly 76 includes a movable rod 761, a rotating rod 762 fixedly connected to the lower end of the movable rod 761, two L-shaped stirring blades 763 fixedly connected to the lower part of the outer surface of the rotating rod 762, and several stirring rods 764 fixedly connected to the right end of each of the two L-shaped stirring blades 763 near the center of the rotating rod 762, and the ends of the several stirring rods 764 near the center of the rotating rod 762 are fixedly connected to the outer surface of the rotating rod 762. The upper end of the movable rod 761 is fixedly connected to the lower end of the driven gear 73. The upper end of the movable rod 761 is movably connected to the upper inner wall of the chemical reactor body 4 through a bearing, and the lower end of the rotating rod 762 is movably connected to the lower inner wall of the chemical reactor body 4 through a rotating shaft.

[0027] Through the above scheme: when the power supply of servo motor 71 is turned on, servo motor 71 starts to run, and its output end drives the fixedly installed drive gear 74 to rotate. When drive gear 74 rotates, it transmits power to toothed transmission belt 75 through meshing, so that it starts to move. The moving toothed transmission belt 75 then meshes with driven gear 73, driving driven gear 73 to rotate synchronously. After driven gear 73 rotates, rotating rod 762 fixedly connected to the lower end of movable rod 761 rotates accordingly. Two L-shaped stirring blades 763 and several stirring rods 764 fixedly connected to the lower part of the outer surface of rotating rod 762 rotate with rotating rod 762 to stir the material in chemical reactor body 4.

[0028] It should be noted that this utility model is a chemical reactor with shock absorption and noise reduction functions. During installation, the three fixing blocks 31 are firmly fixed to the ground by bolts and fixing holes 32 on the fixing blocks 31, ensuring the stability of the chemical reactor body 4. During use, chemical raw materials are slowly injected into the chemical reactor body 4 through the feed pipe 8. The servo motor 71 is started, and the servo motor 71 drives the drive gear 74 to rotate. The drive gear 74 meshes with the driven gear 73 through the toothed transmission belt 75, driving the driven gear 73 to rotate. 3. The stirring assembly 76 is driven to operate, the movable rod 761 and the rotating rod 762 rotate, and the L-shaped stirring blade 763 and the stirring rod 764 stir the material. When the stirring assembly 76 operates and generates vibration, the vibration is transmitted to the top block 36. The damper 34 and the spring 35 in the mounting cylinder 33 work together. The damper 34 absorbs the vibration energy, and the spring 35 elastically deforms to buffer the vibration, reducing the vibration amplitude and noise. After confirming that the stirring and chemical reaction are completed, the switch valve 10 of the discharge pipe 9 is opened, and the chemical material is discharged from the discharge pipe 9 under the action of gravity or pressure.
