Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a defoaming mechanism for a distillation kettle used in chemical product processing. Background Technology

[0002] Distillation kettles are key equipment in chemical processing, widely used in separation, purification, and concentration processes. They separate the gas and liquid components in a mixture based on their boiling point differences through heating. Distillation is an indispensable core process in the production of many chemical products, such as thickeners, fragrances, and solvents. However, when materials are heated to boiling, steam often carries a large number of droplets or foams out of the kettle. These entrained substances not only cause loss of the target product and reduce yield, but may also enter the subsequent condensation system, leading to product contamination, pipeline blockage, or equipment malfunction. Therefore, installing an effective defoaming mechanism in the distillation process to intercept and separate liquid foam from the steam is of great significance for improving product quality, reducing raw material waste, and ensuring stable system operation.

[0003] Existing demister mechanisms mostly adopt a built-in structure, directly installed inside the distillation vessel. Although they can achieve a certain demister effect, they face prominent problems in practical applications, such as inconvenient installation, difficult replacement, and high maintenance costs. Since the demister elements (such as wire mesh, baffles, etc.) are located inside the vessel, once the equipment is put into operation, inspection, cleaning, or replacement must be performed by stopping the machine and opening the vessel lid, which is complicated and time-consuming, seriously affecting production efficiency.

[0004] Therefore, to address the shortcomings of existing technologies, we urgently need a defoaming mechanism for distillation kettles used in chemical product processing. This new technology or equipment should significantly improve the operating efficiency and maintenance convenience of the defoaming system, featuring external installation, easy disassembly and cleaning, and strong anti-clogging capabilities. Simultaneously, it should better meet the demands of modern, intelligent production, providing strong support for the efficient, safe, and clean production of chemical products. Utility Model Content

[0005] The purpose of this invention is to provide a defoaming mechanism for a distillation kettle used in chemical product processing. This solves the problem that existing defoaming mechanisms mostly adopt a built-in structure and are directly installed inside the distillation kettle. Although they can achieve a certain defoaming effect, they face problems such as inconvenient installation, difficult replacement, and high maintenance costs in practical applications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A defoaming mechanism for a distillation kettle used in chemical product processing includes a distillation kettle and an exhaust pipe connected to one side of the top of the distillation kettle. The top of the exhaust pipe is connected to a top outer shell, and a top pipe is connected to one side of the top of the top outer shell. An installation port is provided on one side of the top outer shell. A mounting plate is provided on one side of the mounting port, and a support plate that is inclined and extends through the mounting port into the top shell is connected to one side of the mounting plate. Several through slots are opened on the top of the support plate, and several steel wool balls are connected to the top and bottom of the support plate. The top and bottom sides of the top shell are provided with elastic limiting structures that cooperate with the mounting plate, and both sides of the top shell are provided with positioning structures that can be detachably connected to the mounting plate.

[0007] Preferably, the positioning structure includes a side plate fixedly connected to the side wall of the top housing, a connecting plate fixedly connected to the side wall of the mounting plate, and a positioning screw with one end threaded through the connecting plate, wherein one end of the positioning screw is connected to the side plate.

[0008] Preferably, the elastic limiting structure includes a limiting block and a fixing plate. The fixing plate is connected to the side wall of the top shell. One side of the limiting block is connected to the side wall of the fixing plate through an elastic structure. The top of the limiting block is provided with an upper inclined surface. The bottom corners of the mounting plate are provided with lower inclined surfaces that are adapted to the upper inclined surface.

[0009] Preferably, one end of the positioning screw is fixedly connected to a handle, and the outer ring of the handle has several anti-slip grooves.

[0010] Preferably, the elastic structure includes a movable plate and several compression springs disposed on one side of the fixed plate. One end of each compression spring is connected to the movable plate, and the other end is connected to the fixed plate. Two round rods are connected to one side of the limiting block, and one end of each round rod slides through the side wall of the fixed plate and connects to the movable plate.

[0011] Preferably, a sealing gasket is fixedly connected to one side of the mounting plate, and the limiting block is made of metal.

[0012] This utility model has at least the following beneficial effects: By setting the demister mechanism inside the top outer shell of the distillation vessel and adopting a detachable installation structure, it effectively solves the technical problem of inconvenient installation and replacement of existing built-in demister devices. Especially when improving the function of distillation vessels already in use, there is no need to cut or weld the vessel body itself, avoiding the safety risks and structural damage caused by hot work, and significantly improving the feasibility and safety of equipment modification. The positioning structure set between the mounting plate and the top outer shell enables quick installation and removal of the demister assembly, and the elastic limiting structure provides stable support, so that maintenance does not require long-term waiting for opening the lid, greatly shortening the maintenance cycle and improving production continuity and operating efficiency. The support plate is arranged at an angle and has through grooves. Combined with the steel wool set in the upper and lower layers, it not only increases the probability of airflow disturbance and liquid droplet collision, improving demister efficiency, but also has a certain self-cleaning ability, slowing down the adhesion speed of high-viscosity materials such as thickeners on the surface of the components and reducing the risk of blockage. As a consumable part, the steel wool can be replaced as a whole with the support plate, avoiding the problem of traditional wire mesh demisters requiring on-site cleaning or precision repair, reducing maintenance difficulty and technical requirements.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Example

[0017] Please see Figure 1-5 As shown, the defoaming mechanism of a distillation kettle for chemical product processing in this embodiment includes a distillation kettle 1 and an exhaust pipe 5 connected to one side of the top of the distillation kettle 1. The top of the exhaust pipe 5 is connected to a top outer shell 2, and a top pipe 3 is connected to one side of the top of the top outer shell 2. An installation port 7 is opened on one side of the top outer shell 2. A mounting plate 4 is provided on one side of the mounting port 7. A support plate 6 is connected to one side of the mounting plate 4. The support plate 6 is inclined and extends through the mounting port 7 into the interior of the top shell 2. Several through slots are opened on the top of the support plate 6, and several steel wool balls 9 are connected to the top and bottom of the support plate 6. The top and bottom sides of one side of the top shell 2 are provided with elastic limiting structures that cooperate with the mounting plate 4, and both sides of the top shell 2 are provided with positioning structures that can be detachably connected to the mounting plate 4.

[0018] Workflow: During chemical product processing, when the material in the distillation vessel 1 is heated to boiling, the generated steam, along with entrained droplets and foam, enters the connected top outer shell 2 through the exhaust pipe 5 on one side of the top of the distillation vessel 1. As the steam flows through the top outer shell 2, it first impacts the support plate 6, which is supported by the mounting plate 4 and inclined inside it. The support plate 6 extends into the interior through the mounting opening 7 on the side wall of the top outer shell 2 and is detachably connected to the outside of the top outer shell 2 via the positioning structure of the mounting plate 4. Simultaneously, the elastic limiting structures on both sides of the top outer shell 2 apply a pre-tightening force to the mounting plate 4, ensuring the stability of the overall structure during operation. When the steam passes through the support plate 6, the airflow is dispersed and continues to flow forward through these channels due to the several slots on its surface. Meanwhile, the droplets and foam rising with the steam impact the surface of the support plate 6 under inertia. The equipment consists of multiple steel wool balls 9 fixed on its upper and lower surfaces. These steel wool balls 9 have a large specific surface area and a rough structure, which can effectively capture and gather liquid droplets, causing them to coalesce into larger droplets that flow back to the distillation vessel 1 or down the wall under gravity, thus achieving gas-liquid separation. The purified steam is then discharged from the top pipe 3 on one side of the top of the top shell 2 and enters the subsequent condensation system. When the equipment has been running for a long time and the surface of the steel wool balls 9 becomes dirty or clogged, the operator can first release the positioning structure on both sides of the top shell 2 and overcome the elastic force of the elastic limiting structure to pull the entire mounting plate 4, along with the support plate 6 and the steel wool ball 9 assembly, outward from the mounting port 7 for quick disassembly. This facilitates the cleaning or replacement of the steel wool balls 9. After maintenance, the equipment is pushed back into the mounting port 7 along the original path, the positioning structure is re-locked, and the sealing state is restored under the action of the elastic limiting structure, allowing it to be put back into use. Example

[0019] Please see Figure 1-5 As shown in this embodiment, a defoaming mechanism for a distillation kettle used in chemical product processing includes a positioning structure comprising a side plate 8 fixedly connected to the side wall of the top outer shell 2, a connecting plate fixedly connected to the side wall of the mounting plate 4, and a positioning screw 12 with one end threaded through the connecting plate. One end of the positioning screw 12 is connected to the side plate 8. Specifically, through the cooperation of the side plate 8, the connecting plate, and the positioning screw 12, after the mounting plate 4 is pushed into place, the operator rotates the positioning screw 12 to tighten one end of it to the side plate 8, thereby tightening the connecting plate and the side plate 8, and realizing the detachable fixation of the mounting plate 4 on the top outer shell 2. This structure allows for locking and unlocking operations without the use of additional tools during disassembly and assembly, simplifying the maintenance process, improving the convenience of overall disassembly and installation of the defoaming assembly, effectively shortening equipment downtime, and improving maintenance efficiency.

[0020] A handle is fixedly connected to one end of the positioning screw 12. The outer ring of the handle has several anti-slip grooves. Specifically, by using the handle and anti-slip grooves, the operator can apply torque by gripping the handle with anti-slip grooves when rotating the positioning screw 12 to tighten or loosen it, thereby increasing friction and preventing slippage. This design improves the comfort and safety of operation, especially in humid or oily environments, and can still be operated stably. It also reduces the difficulty of manual operation and further improves the convenience of equipment maintenance. Example

[0021] Please see Figure 1-5 As shown in this embodiment, a defoaming mechanism for a distillation kettle used in chemical product processing includes a limiting block 11 and a fixing plate 13. The fixing plate 13 is connected to the side wall of the top outer shell 2. One side of the limiting block 11 is connected to the side wall of the fixing plate 13 through an elastic structure. The top of the limiting block 11 has an upper inclined surface, and the bottom corners of the mounting plate 4 have lower inclined surfaces 10 that are adapted to the upper inclined surface. Specifically, through the cooperation of the limiting block 11, the fixing plate 13, and the upper and lower inclined surfaces 10, the mounting plate 4 is pushed into the mounting port 7. During the process, the lower inclined surface 10 at the corners on both sides of the bottom slides relative to the upper inclined surface at the top of the limiting block 11, pushing the limiting block 11 to move towards the fixed plate 13 and compressing the elastic structure. When the mounting plate 4 is fully in place, the limiting block 11 automatically rebounds under the action of elastic restoring force and locks the mounting plate 4, forming a pre-tightening limit. This structure realizes the guiding positioning and preliminary fixing functions during the installation process, preventing the mounting plate 4 from loosening due to vibration or airflow impact, enhancing the stability during operation, and providing a basic guarantee for the subsequent locking of the positioning screw 12.

[0022] The elastic structure includes a movable plate 14 and several compression springs 15 disposed on one side of the fixed plate 13. One end of the compression spring 15 is connected to the movable plate 14, and the other end is connected to the fixed plate 13. Two round rods 16 are connected to one side of the limiting block 11. One end of the round rod 16 slides through the side wall of the fixed plate 13 and the movable plate 14. Specifically, through the cooperation of the movable plate 14, the compression springs 15, and the round rods 16 with the fixed plate 13, when the mounting plate 4 is pushed in and the limiting block 11 is compressed, the round rods 16 drive the movable plate 14 to slide on the fixed plate 13, while the compression springs 15 are compressed and store elastic potential energy. When the mounting plate 4 passes the limiting point, the compression springs 15 release energy to push the movable plate 14 to reset, thereby causing the limiting block 11 to spring back to the locked position. This elastic structure provides stable and reliable elastic support, ensuring sensitive and consistent limiting action, and the round rods 16 ensure the linearity and stability of the movement process, extending the service life of the elastic limiting structure.

[0023] A sealing gasket is fixedly connected to one side of the mounting plate 4, and the limiting block 11 is made of metal. Specifically, by setting a sealing gasket on one side of the mounting plate 4 and making the limiting block 11 of metal, when the mounting plate 4 is locked by the positioning structure and the limiting block 11 is pressed, the sealing gasket is deformed by pressure and fills the edge gap of the mounting opening 7, thereby achieving an airtight seal of the internal space of the top shell 2. The limiting block 11 of metal has high strength and temperature resistance, and can maintain structural integrity under long-term thermal expansion and contraction and vibration conditions. It is not easy to deform and fail, thus ensuring the long-term effectiveness of the sealing structure, preventing steam leakage, and improving the safety and reliability of equipment operation.

[0024] In the chemical processing, when the material in the distillation vessel 1 is heated to boiling, the generated high-temperature steam, along with entrained droplets and foam, enters the connected top outer shell 2 through the exhaust pipe 5 on one side of the top of the distillation vessel 1. The steam flows upward within the top outer shell 2, first impacting a support plate 6, which is supported by a mounting plate 4 and inclined inside it. This support plate 6 extends into the top outer shell 2 through a mounting opening 7 on the side wall of the mounting plate 4 and is fixedly connected to the mounting plate 4 to form a detachable assembly. As the steam flows through the support plate 6, the airflow is dispersed by several grooves on its surface and continues to flow forward through these channels, while the rising droplets and foam are dispersed... Under inertia, the liquid impacts the surface of the support plate 6 and the multiple steel wool balls 9 fixed on its upper and lower surfaces. The steel wool balls 9 have a large specific surface area and a rough structure, effectively capturing and agglomerating the liquid droplets into larger droplets that then flow back towards the outlet pipe 5 or down the wall under gravity, thus achieving gas-liquid separation. The purified steam is then discharged from the top pipe 3 connected to the top side of the top shell 2 and enters the subsequent condensation system. Throughout the operation, to ensure the stability and sealing of the mounting plate 4, elastic limiting structures are provided on the top and bottom sides of one side of the top shell 2. These structures include a fixing plate 13 connected to the side wall of the top shell 2. The moving plate 14 is connected to the fixed plate 13 by several compression springs 15. The moving plate 14 is connected to the limiting block 11 by two round rods 16, so that the limiting block 11 can slide on the fixed plate 13 and be reset by the elastic force of the compression springs 15. When the mounting plate 4 is pushed into the mounting opening 7, the lower inclined surface 10 at the corners on both sides of its bottom slides relative to the upper inclined surface at the top of the limiting block 11, pushing the limiting block 11 to compress the compression springs 15 and move inward. When the mounting plate 4 is fully in place, the compression springs 15 release their elastic potential energy, driving the moving plate 14 and the round rods 16 to reset, so that the limiting block 11 automatically rebounds and locks the bottom of the mounting plate 4, forming a preliminary pre-tightening limit. Subsequently, the operator rotates the plate 14 to lock the mounting plate 4. The positioning screw 12—one end of which is threaded through the connecting plate fixed to the side wall of the mounting plate 4 and connected to the side plate 8 fixed to the side wall of the top shell 2—tightens the connecting plate and the side plate 8, thereby achieving the final locking and fixing of the mounting plate 4; the end of the positioning screw 12 is provided with a handle with anti-slip grooves, which is convenient for manual rotation and prevents slippage; at the same time, a sealing gasket is fixed on one side of the mounting plate 4. When the mounting plate 4 is fully compressed, the sealing gasket is deformed by pressure and fills the gap at the edge of the mounting opening 7, achieving an airtight seal inside the top shell 2; the limiting block 11 is made of metal and has good strength and temperature resistance, and can maintain structural stability under long-term thermal expansion and contraction and vibration environment;When prolonged operation of the equipment causes scale buildup or blockage on the surface of the steel wool 9, the operator can first rotate the handle in the opposite direction to loosen the positioning screw 12, releasing the locking state. Then, overcoming the elastic pressure of the limit block 11, the entire mounting plate 4, along with the support plate 6 and the steel wool 9 assembly, can be pulled out from the mounting port 7 for quick disassembly, facilitating cleaning or replacement of the steel wool 9. After maintenance, the mounting plate 4 should be pushed back in along the original path. The guiding action of the upper and lower inclined surfaces 10 will automatically trigger the limit block 11 to spring back and limit the movement. Finally, the positioning screw 12 should be tightened by the handle to complete the final fixation, and operation can be resumed.

[0025] This technical solution, through the coordinated structure of the distillation vessel 1, exhaust pipe 5, top shell 2, top pipe 3, mounting port 7, mounting plate 4, support plate 6, and steel wool 9, effectively intercepts and separates liquid droplets entrained in the steam during distillation, improving product yield and preventing subsequent system contamination. The support plate 6 is inclined and has through slots, which, combined with the steel wool 9 arranged above and below, enhances the gas-liquid contact area and collision efficiency, improving the demisting effect. The mounting plate 4 and top shell 2 are detachably connected, avoiding the drawback of traditional built-in demisters requiring opening the vessel for maintenance, significantly improving maintenance convenience. The positioning structure formed by the side plate 8, connecting plate, and positioning screw 12 enables quick locking and releasing of the mounting plate 4, allowing for disassembly and assembly without additional tools, improving maintenance efficiency. The handle and anti-slip groove at the end of the positioning screw 12 enhances friction and control during operation. Stability is paramount, especially suitable for manual operation in humid or oily environments. The limit block 11, fixed plate 13, moving plate 14, compression spring 15, and round rod 16 in the elastic limit structure work together to provide an automatic rebound limit function during installation, preventing the mounting plate 4 from shifting due to vibration or airflow impact, enhancing operational stability, and providing an initial positioning reference for locking the positioning screw 12. The compression spring 15 provides stable elastic force, and the round rod 16 ensures the straightness of the movement trajectory of the limit block 11, extending the service life of the elastic components. The sealing gasket on one side of the mounting plate 4 deforms under pressure in the locked state, effectively filling the gap at the mounting port 7, preventing steam leakage, and ensuring system sealing. The limit block 11 is made of metal, possessing high mechanical strength and heat resistance, enabling it to work stably for a long time under high temperature and vibration conditions, and is not prone to deformation or failure, ensuring the long-term reliability of the limit and sealing functions.
