Description

Technical Field

[0001] This utility model relates to the field of enamel-lined reactor technology, specifically to a surfactant enamel-lined reactor that facilitates material feeding. Background Technology

[0002] Enameled reactors are reaction equipment made by coating a metal substrate with an enamel layer. They combine the high strength of metal with the corrosion resistance and wear resistance of enamel, and are widely used in processes such as surfactant synthesis in chemical and pharmaceutical industries. A typical reactor includes a vessel body, a lid, a stirring system, and optional heating / cooling jackets. Precise reaction can be ensured by controlling temperature and pressure. In surfactant production, enamel reactors can adapt to various material reaction requirements. When adding materials, standardized procedures must be followed, such as controlling the loading coefficient and using specialized tools to assist in addition, to avoid material impact damaging the enamel layer. With its stable physicochemical properties, this type of equipment provides a safe and reliable operating environment for surfactant synthesis and other reactions, making it a commonly used key piece of equipment in related industrial production.

[0003] In existing technologies, there is a lack of vibrating screw feeding function, and since most surfactant raw materials are in powder or semi-fluid form, simple gravity feeding or static screw feeding can easily cause blockages due to the adsorption and friction between raw materials, leading to feeding interruptions and requiring frequent shutdowns for unblocking, which affects production continuity. In addition, in existing technologies, unidirectional stirring can easily cause raw materials to flow in a fixed direction, forming local circulation, resulting in uneven mixing of raw materials in different areas, affecting the consistency of surfactant reaction. At the same time, the relative motion speed generated by unidirectional stirring is limited, and for surfactant raw materials with high viscosity or easy agglomeration, it takes longer to achieve initial mixing, extending the overall production cycle. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a surfactant enamel reactor that facilitates feeding. It solves the technical problems in the prior art where, during simple gravity feeding or static spiral feeding, blockages easily form due to the adsorption and friction between raw materials, leading to feeding interruption; unidirectional stirring easily causes the raw materials to flow in a fixed direction, forming local circulation, resulting in uneven mixing of raw materials in different areas; and for surfactant raw materials with high viscosity or easy agglomeration, it takes longer to achieve initial mixing, thus prolonging the overall production cycle.

[0005] According to one aspect, at least one embodiment of the present invention provides a surfactant-lined reactor for easy feeding, comprising: A mobile frame is provided, with four rectangular self-locking casters fixedly connected to the bottom of the mobile frame. An enamel-lined reactor is fixedly connected inside the mobile frame. A sealing cover is fixedly connected to the top of the enamel-lined reactor by bolts. A controller is fixedly connected to the front side of the outer wall of the enamel-lined reactor. A discharge valve electrically connected to the controller is fixedly connected to the bottom discharge pipe of the enamel-lined reactor. A vibrating screw feeding assembly is located on the top rear side of the mobile frame. The vibrating screw feeding assembly is used to feed raw materials into the enamel-lined reactor, and at the same time, vibration is used to prevent the raw materials from clogging during the feeding process. A coaxial bidirectional stirring assembly is installed inside the enamel-lined reactor and on top of the sealing cover. The coaxial bidirectional stirring assembly is used to coaxially and bidirectionally stir the raw materials in the enamel-lined reactor in order to improve stirring efficiency.

[0006] For example, in a surfactant enamel reactor that facilitates feeding, provided in at least one embodiment of this utility model, the vibrating screw feeding assembly includes a fixed plate, which is fixedly connected to the top rear side of the movable frame. Four sliding rods are fixedly connected to the top of the fixed plate, and lifting plates are slidably connected to the outer walls of the four sliding rods. Limit blocks are fixedly connected to the top of each of the four sliding rods. Two symmetrical springs are fixedly connected to the opposite surfaces of the fixed plate and the lifting plates. A motor is fixedly connected to the top left side of the fixed plate, and a toothed pulley is fixedly connected to the output end of the motor.

[0007] For example, in a surfactant enamel reactor that facilitates feeding, provided by at least one embodiment of the present invention, two symmetrical fixed blocks located directly below a lifting plate are fixedly connected to the top of the fixed plate. An eccentric wheel is rotatably connected to the opposite surfaces of the two fixed blocks. The front end of the eccentric wheel extends through the front sidewall of the front fixed block and is fixedly connected to a toothed pulley. The outer walls of the toothed pulleys are fitted with toothed synchronous belts that mesh with them. A roller seat is fixedly connected to the bottom of the lifting plate. A roller is rotatably connected inside the roller seat. The roller is movably connected to the eccentric wheel.

[0008] For example, in a surfactant enamel reactor provided by at least one embodiment of the present invention, a feeding cylinder is fixedly connected to the top of the lifting plate, a feeding hopper is fixedly connected to the top of the outer wall of the feeding cylinder, an auger is rotatably connected inside the feeding cylinder, a second motor is fixedly connected to the rear side of the feeding cylinder, the output end of the second motor passes through the interior of the feeding cylinder and is fixedly connected to the auger, a bellows is fixedly connected to the front side of the feeding cylinder, and the end of the bellows away from the feeding cylinder passes through the sealing cover and extends into the interior of the enamel reactor.

[0009] For example, in a surfactant enamel reactor that facilitates feeding, provided in at least one embodiment of this utility model, the controller is electrically connected to motor two and motor one respectively.

[0010] For example, in a surfactant enamel reactor for easy feeding provided by at least one embodiment of this utility model, the coaxial bidirectional stirring assembly includes two side plates, which are fixedly connected to the top of the sealing cover. A rotating rod is rotatably connected to the opposite surfaces of the front and rear side plates. Two helical gears are fixedly connected to the outer wall of the rotating rod. A motor is fixedly connected to the front side wall of the front side plate. The output end of the motor extends through to the rear side wall of the front side plate and is fixedly connected to the rotating rod. Helical gears are meshed with the left sides of both rotating rods. A stirring rod is fixedly connected to the interior of the rear helical gear. A hollow rotating rod that is rotatably connected to the sealing cover is rotatably connected to the outer wall of the stirring rod. A gear is fixedly connected to the outer wall of the hollow rotating rod. A gear is meshed with the front side of the gear. A rotating rod that is rotatably connected to the sealing cover is fixedly connected to the interior of the gear. The top of the outer wall of the rotating rod is fixedly connected to the front helical gear.

[0011] For example, in a surfactant enamel reactor provided by at least one embodiment of the present invention, the bottom of both the stirring rod and the hollow rotating rod penetrates the sealing cover and extends into the interior of the enamel reactor. A rotating stirring frame is fixedly connected to the outer wall of the hollow rotating rod, and a plurality of stirring plates distributed at equal vertical distances are fixedly connected to the inner wall of the rotating stirring frame. A plurality of stirring blades distributed at equal vertical distances are fixedly connected to the outer wall of the stirring rod, and the stirring blades are staggered with the stirring plates on the inner wall of the rotating stirring frame.

[0012] For example, in a surfactant enamel reactor that facilitates feeding, provided in at least one embodiment of this utility model, the controller is electrically connected to the motor.

[0013] The beneficial effects of the embodiments of this utility model are as follows: In this invention, the vibrating spiral feeding component enables the spiral conveying structure to continuously push raw materials. Combined with vibration, this breaks down the static friction and adsorption forces between the raw materials, preventing accumulation or bridging at the bottom of the hopper and in the conveying channel, ensuring a continuous and smooth feeding process. The combination of spiral conveying and vibration accelerates the flow of raw materials, reducing the time spent manually clearing blockages. Compared to simple gravity feeding or static spiral feeding, this significantly increases the amount of material fed per unit time. Furthermore, the coaxial bidirectional stirring component, with its bidirectional rotating stirring structure (inner stirring blades rotating in opposite directions to the outer stirring frame), creates complex convection and shearing motions within the reactor, ensuring thorough contact between surfactant raw materials of different densities and viscosities. This avoids uneven mixing in certain areas. The greater relative speed generated by the opposing rotations quickly breaks down stratification or agglomeration between raw materials, achieving uniform mixing in a shorter time compared to unidirectional stirring, thus shortening the reaction cycle.

[0023] like Figures 1-5 As shown, it illustrates a surfactant-lined reactor for easy feeding according to an embodiment of the present invention, comprising: The mobile frame 1 has four rectangular self-locking casters 10 fixedly connected to its bottom. An enamel-lined reactor 11 is fixedly connected inside the mobile frame 1. A sealing cover 14 is fixedly connected to the top of the enamel-lined reactor 11 by bolts.

The coaxial bidirectional stirring assembly 3 is installed inside the enamel-lined reactor 11 and on top of the sealing cover 14. The coaxial bidirectional stirring assembly 3 is used to coaxially and bidirectionally stir the raw materials in the enamel-lined reactor 11 in order to improve the stirring efficiency.

[0024] Furthermore, the mobile frame 1 serves as the supporting foundation for the entire equipment. Four rectangularly distributed self-locking casters 10 (model SWL-50) are fixedly connected to its bottom for easy movement and fixation. An enamel-lined reactor 11 is fixedly connected inside the mobile frame 1. The outer wall of the enamel-lined reactor 11 has a vacuum jacket.

A discharge valve 12 (model Q641F-16C pneumatic ball valve) is fixedly connected to the bottom discharge pipe of the enamel-lined reactor 11, and the discharge valve 12 is electrically connected to the controller 13, allowing its opening and closing to be controlled by the controller 13.

[0025] The vibrating screw feeding assembly 2 includes a fixed plate 20, which is fixedly connected to the top rear side of the mobile frame 1. Four slide rods 21 are fixedly connected to the top of the fixed plate 20. Lifting plates 22 are slidably connected to the outer walls of the four slide rods 21. Limit blocks are fixedly connected to the top of each of the four slide rods 21. Two left-right symmetrical springs 23 are fixedly connected to the opposite surfaces of the fixed plate 20 and the lifting plates 22. A motor 24 is fixedly connected to the top left side of the fixed plate 20. A toothed pulley 25 is fixedly connected to the output end of the motor 24.

[0026] The top of the fixed plate 20 is fixedly connected to two symmetrical fixed blocks 27 located directly below the lifting plate 22. The opposite surfaces of the two fixed blocks 27 are rotatably connected to an eccentric wheel 28. The front end of the eccentric wheel 28 extends through to the front side wall of the front fixed block 27 and is fixedly connected to a toothed pulley 26. The outer walls of the toothed pulley 25 and the toothed pulley 26 are fitted with toothed synchronous belts that mesh with them. The bottom of the lifting plate 22 is fixedly connected to a roller seat 29. The inside of the roller seat 29 is rotatably connected to a roller 210, which is movably connected to the eccentric wheel 28.

[0027] A conveying cylinder 211 is fixedly connected to the top of the lifting plate 22. A feeding hopper 212 is fixedly connected to the top of the outer wall of the conveying cylinder 211. An auger 213 is rotatably connected inside the conveying cylinder 211. A second motor 214 is fixedly connected to the rear side of the conveying cylinder 211. The output end of the second motor 214 passes through the interior of the conveying cylinder 211 and is fixedly connected to the auger 213. A bellows 215 is fixedly connected to the front side of the conveying cylinder 211. The end of the bellows 215 away from the conveying cylinder 211 passes through the sealing cover 14 and extends into the interior of the enamel-lined reactor 11.

[0028] The controller 13 is electrically connected to motor 214 and motor 1 24 respectively.

[0029] In some examples, a lifting plate 22 is slidably connected to the outer wall of the four slide rods 21. Limit blocks are fixedly connected to the top of each of the four slide rods 21 to prevent the lifting plate 22 from slipping. Two left-right symmetrical springs 23 are fixedly connected to the opposite surface of the fixed plate 20 and the lifting plate 22. Two front-back symmetrical fixing blocks 27 located directly below the lifting plate 22 are fixedly connected to the top of the fixed plate 20. An eccentric wheel 28 is rotatably connected to the opposite surface of the front and rear fixing blocks 27. The eccentric wheel 28 has a rotating shaft structure. The front end of the eccentric wheel 28 extends through the front side wall of the front fixing block 27 and is fixedly connected to a toothed pulley. The outer walls of toothed pulleys 26 and 25 are fitted with toothed synchronous belts that mesh with them. The bottom of the lifting plate 22 is fixedly connected to a roller seat 29. The roller seat 29 is rotatably connected to a roller 210. The roller 210 is movably connected to an eccentric wheel 28. The front side of the conveying cylinder 211 is fixedly connected to a bellows 215. The bellows 215 is made of food-grade stainless steel. The end of the bellows away from the conveying cylinder 211 passes through the sealing cover 14 and extends into the interior of the enamel-lined reactor 11. The controller 13 is electrically connected to motor 214 and motor 24 respectively to control their operation.

[0030] When surfactant production is required, the equipment is first moved to the designated position and locked by the self-locking casters 10 at the bottom of the mobile frame 1. The controller 13 starts the vibrating screw feeding assembly 2. The controller 13 simultaneously sends working signals to motor 1 24 and motor 214. After motor 1 24 starts, it drives toothed pulley 1 25 to rotate. The toothed pulley 26 and eccentric wheel 28 are driven to rotate synchronously through the toothed synchronous belt. During the rotation, the eccentric wheel 28 continuously pushes the roller 210, causing the lifting plate 22 to move up and down along the slide bar 21. At the same time, the spring 23 provides the reset force to realize the high-frequency vibration of the lifting plate 22. Meanwhile, motor 214 drives the auger 213 to rotate in the feeding cylinder 211. The operator pours the raw material into the feeding hopper 212. The raw material moves forward under the pushing action of the auger 213 and the vibration of the feeding cylinder 211, and finally enters the enameled reactor 11 through the bellows 215. The vibration effectively avoids the blockage of the raw material during the feeding process. In this embodiment, the vibrating screw feeding component 2 enables the screw conveyor structure to continuously push raw materials. The vibration action breaks down the static friction and adsorption forces between the raw materials, preventing them from accumulating or bridging at the bottom of the feeding hopper or in the conveying channel, thus ensuring a continuous and smooth feeding process. At the same time, the combination of screw conveying and vibration can accelerate the flow rate of the raw materials and reduce the time spent manually clearing blockages. Compared with simple gravity feeding or static screw feeding, it can significantly increase the amount of material fed per unit time.

[0031] like Figure 6As shown, this invention illustrates a coaxial bidirectional stirring assembly 3 in another embodiment. The coaxial bidirectional stirring assembly 3 includes two side plates 30, which are fixedly connected to the top of the sealing cover 14. A rotating rod 31 is rotatably connected to the opposing surfaces of the front and rear side plates 30. Two helical gears 33 are fixedly connected to the outer wall of the rotating rod 31. A motor 32 is fixedly connected to the front side plate 30. The output end of the motor 32 extends through to the rear side wall of the front side plate 30 and is fixedly connected to the rotating rod 31. The left side of the rotating rod 31 is meshed with a helical gear 34. The rear helical gear 34 is fixedly connected to a stirring rod 35. The outer wall of the stirring rod 35 is rotatably connected to a hollow rotating rod 36 that is rotatably connected to the sealing cover 14. The outer wall of the hollow rotating rod 36 is fixedly connected to a gear 37. The front side of the gear 37 is meshed with a gear 311. The inside of the gear 311 is fixedly connected to a rotating rod 38 that is rotatably connected to the sealing cover 14. The top of the outer wall of the rotating rod 38 is fixedly connected to the front helical gear 34.

[0032] The bottoms of both the stirring rod 35 and the hollow rotating rod 36 penetrate the sealing cover 14 and extend into the interior of the enamel-lined reactor 11. A rotating stirring frame 39 is fixedly connected to the outer wall of the hollow rotating rod 36. Several stirring plates with equal vertical spacing are fixedly connected to the inner wall of the rotating stirring frame 39. Several stirring blades 310 with equal vertical spacing are fixedly connected to the outer wall of the stirring rod 35. The stirring blades 310 and the stirring plates on the inner wall of the rotating stirring frame 39 are staggered.

[0033] The controller 13 is electrically connected to the motor 32.

[0034] In some examples, the component includes two side plates 30, which are fixedly connected to the top of the sealing cover 14. A rotating rod 31 is rotatably connected to the opposite surfaces of the two side plates 30. Two helical gears 33 are fixedly connected to the outer wall of the rotating rod 31. A motor 32 is fixedly connected to the front wall of the front side plate 30, with its output end extending through to the rear wall of the front side plate 30 and fixedly connected to the rotating rod 31. Helical gears 34 are meshed with the left sides of both rotating rods 31. A stirring rod 35 is fixedly connected inside the rear helical gear 34. A hollow rotating rod 36, rotatably connected to the sealing cover 14, is rotatably connected to the outer wall of the stirring rod 35. A gear 37 is fixedly connected to the outer wall of the hollow rotating rod 36. The front of the gear 37... A gear 311 is connected to the side meshing. A rotating rod 38, which is rotatably connected to the sealing cover 14, is fixedly connected inside the gear 311. The top of the outer wall of the rotating rod 38 is fixedly connected to the front helical gear 34. The bottoms of the stirring rod 35 and the hollow rotating rod 36 both penetrate the sealing cover 14 and extend into the interior of the enamel-lined reactor 11. A rotating stirring frame 39 is fixedly connected to the outer wall of the hollow rotating rod 36. Several stirring plates with equal vertical spacing are fixedly connected to the inner wall of the rotating stirring frame 39. Several stirring blades 310 with equal vertical spacing are fixedly connected to the outer wall of the stirring rod 35. The stirring blades 310 and the stirring plates on the inner wall of the rotating stirring frame 39 are staggered. The controller 13 is electrically connected to the motor 32 to control its working state.

[0035] After feeding is completed, the operator switches to the stirring mode via controller 13. Controller 13 shuts down motor 1 24 and motor 214, and simultaneously starts motor 32. The output of motor 32 drives rotating rod 1 31 to rotate between the two side plates 30. The two helical gears 1 33 fixed on rotating rod 1 31 rotate synchronously. The front helical gear 1 33 meshes with the front helical gear 2 34, driving rotating rod 2 38 to rotate. Gear 2 311 at the bottom of rotating rod 2 38 meshes with gear 1 37, thereby driving hollow rotating rod 36 to rotate on sealing cover 14. This causes the rotating stirring frame 39 fixed at the bottom of hollow rotating rod 36 to rotate along with it. The stirring plates on the inner wall of the rotating stirring frame 39 affect the enamel-lined reactor 1. The raw materials in the inner region are stirred, and at the same time, the rear helical gear 33 and the rear helical gear 34 mesh and drive the stirring rod 35 to rotate in the opposite direction inside the hollow rotating rod 36. This causes the stirring blades 310 fixed at the bottom of the stirring rod 35 to rotate in the opposite direction as well, stirring the raw materials in the central region of the enamel reactor 11. Since the stirring blades 310 and the stirring plates on the inner wall of the rotating stirring frame 39 are staggered and rotate in the opposite direction, the raw materials in the enamel reactor 11 can form complex convection and shear motion, which greatly improves the uniformity and efficiency of stirring. After the stirring reaction is completed, the controller 13 sends a signal to open the discharge valve 12, and the finished surfactant product after the reaction is discharged through the discharge pipe at the bottom of the enamel reactor 11. In this embodiment, the coaxial bidirectional stirring assembly 3, with its bidirectional rotating stirring structure (the inner stirring blades and the outer stirring frame rotating in opposite directions), can form complex convection and shear motions within the reactor, allowing surfactant raw materials of different densities and viscosities to come into full contact, thus avoiding the problem of uneven mixing of local raw materials. At the same time, the relative speed generated by the two rotating in opposite directions is greater, which can quickly break up the layering or agglomeration between raw materials. Compared with unidirectional stirring, it can achieve uniform mixing of raw materials in a shorter time and shorten the reaction cycle.

[0036] The working principle and usage process of this utility model are as follows: When surfactant production is required, the equipment is first moved to the designated position and locked by the self-locking casters 10 at the bottom of the moving frame 1. The controller 13 is then activated to start the vibrating screw feeding assembly 2. The controller 13 simultaneously sends working signals to motor 1 24 and motor 214. After motor 1 24 starts, it drives toothed pulley 1 25 to rotate. The toothed synchronous belt drives toothed pulley 26 and eccentric wheel 28 to rotate synchronously. During the rotation, eccentric wheel 28 continuously pushes against the surface. The roller 210 pushes the lifting plate 22 to move up and down along the slide bar 21, while the spring 23 provides a restoring force, achieving high-frequency vibration of the lifting plate 22. At the same time, the motor 214 drives the auger 213 to rotate inside the conveying cylinder 211. The operator pours the raw material into the feeding hopper 212. The raw material moves forward under the pushing action of the auger 213 and the vibration of the conveying cylinder 211, and finally enters the enameled reactor 11 through the bellows 215. The vibration effectively prevents the raw material from clogging during the feeding process. In this embodiment, the vibrating spiral feeding component 2 continuously pushes the raw material through the spiral conveying structure. Combined with the vibration, it breaks the static friction and adsorption between the raw materials, preventing the raw materials from accumulating or "bridging" at the bottom of the feeding hopper and in the conveying channel, ensuring a continuous and smooth feeding process. At the same time, the combination of spiral conveying and vibration can accelerate the flow speed of the raw material and reduce the time spent manually clearing blockages. Compared with simple gravity feeding or static spiral feeding, it can significantly increase the feeding amount per unit time.

[0037] After feeding is completed, the operator switches to the stirring mode via controller 13. Controller 13 shuts down motor 1 24 and motor 214, and simultaneously starts motor 32. The output of motor 32 drives rotating rod 1 31 to rotate between the two side plates 30. The two helical gears 1 33 fixed on rotating rod 1 31 rotate synchronously. The front helical gear 1 33 meshes with the front helical gear 2 34, driving rotating rod 2 38 to rotate. Gear 2 311 at the bottom of rotating rod 2 38 meshes with gear 1 37, thereby driving hollow rotating rod 36 to rotate on sealing cover 14. This causes the rotating stirring frame 39 fixed at the bottom of hollow rotating rod 36 to rotate along with it. The stirring plates on the inner wall of the rotating stirring frame 39 affect the enamel-lined reactor 1. The raw materials in the inner region are stirred, and at the same time, the rear helical gear 33 and the rear helical gear 34 mesh and drive the stirring rod 35 to rotate in the opposite direction inside the hollow rotating rod 36. This causes the stirring blades 310 fixed at the bottom of the stirring rod 35 to rotate in the opposite direction as well, stirring the raw materials in the central region of the enamel reactor 11. Since the stirring blades 310 and the stirring plates on the inner wall of the rotating stirring frame 39 are staggered and rotate in the opposite direction, the raw materials in the enamel reactor 11 can form complex convection and shear motion, which greatly improves the uniformity and efficiency of stirring. After the stirring reaction is completed, the controller 13 sends a signal to open the discharge valve 12, and the finished surfactant product after the reaction is discharged through the discharge pipe at the bottom of the enamel reactor 11. In this embodiment, the coaxial bidirectional stirring assembly 3, with its bidirectional rotating stirring structure (the inner stirring blades and the outer stirring frame rotating in opposite directions), can form complex convection and shear motions within the reactor, allowing surfactant raw materials of different densities and viscosities to come into full contact, thus avoiding the problem of uneven mixing of local raw materials. At the same time, the relative speed generated by the two rotating in opposite directions is greater, which can quickly break up the layering or agglomeration between raw materials. Compared with unidirectional stirring, it can achieve uniform mixing of raw materials in a shorter time and shorten the reaction cycle.

[0038] It should be noted that the discharge valve 12, controller 13, and various motors are all common models on the market, and each component is a device or equipment that exists in the prior art or can be implemented by the prior art.
