Description

Technical Field

[0001] This invention relates to the field of corrosion inhibitor production technology, and in particular to a reaction apparatus for organic synthesis of corrosion inhibitors. Background Technology

[0002] Organic synthesis is a core processing technology in the field of fine chemicals and is widely used in the preparation and production of various auxiliaries, reagents and functional chemical products. Among them, corrosion inhibitors, as key auxiliaries in industrial anti-corrosion systems, can effectively slow down the corrosion rate of metal equipment and pipelines and are widely used in many industrial fields such as petrochemicals, machinery manufacturing and water treatment.

[0003] Currently, the preparation and processing of organic synthetic corrosion inhibitors generally adopts reaction vessels to complete the synthesis reaction. In order to ensure the orderly progress of the synthesis reaction, the industry uses stirring structures to continuously stir and mix the raw materials in the vessel to promote material contact reaction. However, in the actual production process, especially for oil-soluble corrosion inhibitors, which have a wide range of applications, the core raw material for oil-soluble corrosion inhibitors, oleic acid imidazoline, is a highly viscous oily liquid with poor fluidity, slow diffusion rate, and high viscosity. At present, the solutions of various main materials, auxiliary additives, and reflux water-removing agents required by the process are mostly concentrated in a single position at the top of the reaction vessel. The newly added materials cannot diffuse quickly into the upper and lower layers of materials in the vessel, and are prone to material enrichment and accumulation at the feeding position. This results in extremely low mixing efficiency between the newly added raw materials and the original base materials in the vessel, serious material stratification, poor overall mixing uniformity, and a significant reduction in the organic synthesis reaction rate. It is also prone to problems such as incomplete local reaction and inconsistent reaction degree, ultimately causing quality defects such as insufficient purity, unstable performance, and large batch differences in the finished corrosion inhibitor.

[0004] Therefore, the present invention provides an organic synthesis corrosion inhibitor reaction apparatus to overcome the above-mentioned shortcomings. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an organic synthesis corrosion inhibitor reaction device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An organic synthesis corrosion inhibitor reaction apparatus, comprising: Reactor; A fixed column extends through the top of the reactor and is rotatably connected to it via a bearing. Several stirring rods are installed on the bottom sidewall of the fixed column inside the reactor. A drive mechanism, mounted on the reactor, is used to drive the fixed column to rotate; A hollow cavity is provided inside the fixed column, and a liftable piston is installed inside the hollow cavity. The ends of the plurality of stirring rods are provided with drainage channels, and the plurality of drainage channels are all connected to the hollow cavity. The drainage channels are provided with sealing elements. A feeding mechanism, which is mounted on the fixed column, is used to inject material into the hollow cavity; Several shovels are rotatably connected to the bottom of the fixed column in a circular array, and a power component is provided between them. The power component works in conjunction with a piston. When the piston descends or rises, the power component can drive the several shovels to rotate synchronously.

[0007] As a further aspect of the present invention, the driving mechanism includes: A drive motor is mounted on the top of the reactor via a bracket, and its output end is connected to a first bevel gear. A second bevel gear is mounted on one end of the fixed column near the top of the reactor, and the second bevel gear meshes perpendicularly with the first bevel gear. A protective cover is installed outside the second bevel gear and the first bevel gear, and its bottom end is fixedly connected to the reactor.

[0008] As a further embodiment of the present invention, the top end of the hollow cavity is connected to the outside of the fixed column, and the top end of the fixed column is supported by a bracket to mount an electric push rod, the bottom end of the electric push rod extending into the hollow cavity and being fixedly connected to the piston.

[0009] As a further aspect of the present invention, the feeding mechanism includes: The bottom end of the U-shaped infusion tube is connected to the top end of the fixed column, and a solenoid valve is installed at the connection point. The main pipeline is located above the fixed column, and the central axes of the two coincide. The bottom end of the main pipeline is rotatably connected to the top end of the U-shaped infusion tube through a rotary joint, and the side wall of the main pipeline is connected to several collection tanks through branch pipelines.

[0010] As a further embodiment of the present invention, a connecting column is provided between the plurality of stirring rods in the same vertical direction, and a connecting cavity is provided inside the connecting column. The plurality of drainage channels are connected to each other through the connecting cavity, and the two lowest sets of drainage channels are connected to the bottom end of the hollow cavity.

[0011] As a further aspect of the present invention, the sealing element includes: The receiving cavity is located at the opening end of the drainage channel, and a spring is fixedly connected to one end of the receiving cavity. A limiting block located outside the stirring rod is provided at one end of the spring.

[0012] As a further aspect of the present invention, the power assembly includes: A positioning post is installed through the bottom end of the fixed post. The top end of the positioning post is located inside the hollow cavity and is provided with an elastic head. The bottom end of the positioning post is located outside the fixed post and is provided with a protrusion. The bottom side of the protrusion is rotatably connected to several shovel plates by a connecting rod through a rotating shaft.

[0013] As a further embodiment of the present invention, a support rod is detachably connected to the middle of the bottom side of the protrusion, and a crushing blade is provided at the bottom end of the support rod.

[0014] As a further embodiment of the present invention, the top end of the support rod is provided with a threaded head, and the bottom side of the protrusion is provided with a threaded groove that matches the threaded head.

[0015] The technical effects and advantages provided by the present invention in the above technical solution are as follows: This invention utilizes a feeding structure composed of a hollow cavity, a flow channel, and a sealing element in the stirring structure. With the cooperation of components such as the feeding mechanism, new raw materials can be simultaneously sprayed from different heights inside the reactor and uniformly pressed into the reaction material system inside the reactor. This allows the new raw materials to fully mix with the existing materials in the reactor, achieving layered and uniform feeding, greatly improving the uniformity of material mixing, and thus effectively accelerating the organic synthesis reaction rate and ensuring the full progress of the corrosion inhibitor synthesis reaction. The feeding structure is integrated inside the mixing structure, eliminating the need for additional feeding components, saving space inside the vessel and not affecting the mixing operation. It is streamlined, reasonable, and has good performance. By setting multiple sets of shovels, and with the cooperation of the power unit, the material can be sprayed out and simultaneously flipped upwards, breaking up the material deposited at the bottom of the vessel. At the same time, the linkage support rod and the crushing blades extend the crushing blades to the discharge port at the bottom of the vessel. As the overall stirring structure rotates, the crushing blades rotate synchronously to cut and break up the condensed and agglomerated material at the discharge port. Furthermore, by driving the piston to rise and reset, a negative pressure can be formed in the hollow cavity to further tighten the limiting block against the outlet end of the flow channel, thereby enhancing the sealing effect. At the same time, multiple sets of shovels will fall back synchronously, disturbing the material at the bottom of the vessel again and further improving the overall mixing reaction effect. Meanwhile, the crushing blades can reset and rise synchronously, thus not affecting the subsequent normal material discharge operation. Attached Figure Description

Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1-6As shown, an organic synthesis corrosion inhibitor reaction apparatus includes: a reaction vessel 100, a fixed column 200, a drive mechanism, a hollow cavity 202, a feeding mechanism, and several shovels 804; wherein, the fixed column 200 passes through the top of the reaction vessel 100 and is rotatably connected to it via bearings, and several stirring rods 201 are provided on the bottom sidewall of the fixed column 200 inside the reaction vessel 100; the drive mechanism is located on the reaction vessel 100 and is used to drive the fixed column 200 to rotate; the hollow cavity 202 is located inside the fixed column 200, and a liftable... Piston 401 and several stirring rods 201 are provided with flow channels 2011 at their ends. The flow channels 2011 are all connected to the hollow cavity 202 and are provided with seals. The feeding mechanism is provided on the fixed column 200 and is used to inject material into the hollow cavity 202. Several shovels 804 are rotatably connected to the bottom of the fixed column 200 in a ring array and are provided with a power assembly between them. The power assembly works in conjunction with piston 401. When piston 401 descends or rises, the power assembly can drive several shovels 804 to rotate synchronously.

[0020] In one specific embodiment of the present invention, by Figure 5 It is understood that the driving mechanism includes a drive motor 300, which is mounted on the top of the reactor 100 via a bracket, and its output end is connected to a first bevel gear 301. A second bevel gear 302 is mounted on one end of the fixed column 200 near the top of the reactor 100. The second bevel gear 302 meshes perpendicularly with the first bevel gear 301. By starting the drive motor 300, the drive motor 300 can drive the first bevel gear 301 to rotate, which in turn drives the meshing second bevel gear 302 to rotate. This allows the second bevel gear 302 to drive the fixed column 200 to rotate at the top of the reactor 100. A protective cover is installed over the second bevel gear 302 and the first bevel gear 301, and its bottom end is fixedly connected to the reactor 100. The protective cover can cover the bevel gear assembly to prevent the surrounding environment from affecting the bevel gear assembly, thereby increasing stability and service life.

[0021] The top of the hollow cavity 202 is connected to the outside of the fixed column 200. The top of the fixed column 200 is supported by an electric push rod 400. The bottom end of the electric push rod 400 extends into the hollow cavity 202 and is fixedly connected to the piston 401. The electric push rod 400 can drive the piston 401 to slide up and down along the inner wall of the hollow cavity 202. It should be noted that the piston 401 is sealed and slidably assembled inside the hollow cavity 202. The top of the hollow cavity 202 is connected to the outside, which can ensure that the air pressure in the upper hollow cavity is always balanced with the outside air pressure during the sliding of the piston 401.

[0022] In one specific embodiment of the present invention, the feeding mechanism includes: a U-shaped infusion tube 500, the bottom end of which is connected to the top end of the fixed column 200, and a solenoid valve 501 is provided at the connection point. By providing the solenoid valve 501 at the inlet of the connection point, the solenoid valve 501 can control the opening and closing of the pipeline, so that when the piston 401 moves to below the bottom end of the U-shaped infusion tube 500, the solution material in the U-shaped infusion tube 500 will not be injected into the upper hollow cavity again; and a main pipeline 502, which is located above the fixed column 200, and the central axes of the two are aligned. The bottom end of the main pipeline 502 is rotatably connected to the top end of the U-shaped infusion tube 500 through a rotary joint. Through the adaptability of the rotary joint, the main pipeline 502 remains stationary when the U-shaped infusion tube 500 rotates synchronously with the fixed column 200, effectively avoiding damage from pipeline twisting, pulling and bending, and ensuring the sealing and motion adaptability of the pipeline connection. In addition, the side wall of the main pipeline 502 is connected to several collection tanks 503 through branch pipelines. Each collection tank 503 is independent of each other and can store different types of reaction raw materials or recycled materials.

[0023] It should be noted that each collection tank 503 is equipped with a control valve at the bottom of the section between it and the main pipeline 502. By opening and closing different control valves, the required materials can be flexibly selected to flow into the main pipeline 502, realizing selective feeding of various materials and adapting to the synthesis and processing of corrosion inhibitors with different formulations. The collection tank 503 can be used as a storage container for reaction materials to continuously supply raw materials for the synthesis reaction inside the reactor 100. It can also be used as a reflux recovery container connected to the reactor 100. For example, it can be used as a reflux recovery container for water-carrying agents (fatty acids and polyamines dehydrate and cyclize to generate water. If the water remains in the reactor, it will cause a reverse reaction and reduce the conversion rate. The water-carrying agent is used to carry water in an azeotropic manner. After condensation, the water phase is separated, and the solvent is refluxed back to the reactor to continue participating in the reaction). The water-carrying agent is first received and recovered, and then the recovered water-carrying agent is refluxed back into the reactor. These are all conventional technical means in the field and are not the focus of the improvement of this invention. Therefore, they will not be described in detail.

[0024] The fixed column 200 is driven to rotate by the drive mechanism, which in turn drives multiple sets of stirring rods 201 to rotate inside the reactor 100. This stirring structure can stir and mix the mixture inside the reactor 100.

[0025] like Figures 6-9As shown, a connecting column 600 is provided between multiple stirring rods 201 in the same vertical direction. The connecting column 600 has a connecting cavity 601 inside. Multiple drainage channels 2011 are connected through the connecting cavity 601, and the two lowest sets of drainage channels 2011 are connected to the bottom end of the hollow cavity 202. The connecting column 600 can further strengthen the connection strength between multiple stirring rods 201 in the same longitudinal direction. The connecting cavity 601 can connect multiple drainage channels 2011. Since the two lowest sets of drainage channels 2011 are connected to the bottom end of the hollow cavity 202, all drainage channels 2011 are connected to the hollow cavity 202. The design of the lowest connection position can ensure that the upper hollow cavity will not connect with the drainage channels 2011 when the piston 401 is lowered to the bottom, thereby preventing leakage and ensuring safety.

[0026] The sealing element includes a receiving cavity 2012, which is located at the opening end of the drainage channel 2011, and a spring 701 is fixedly connected to one end of the receiving cavity 2012. A limiting block 700 located outside the stirring rod 201 is provided at one end of the spring 701.

[0027] In the initial state, piston 401 is positioned above the liquid inlet of hollow cavity 202. By opening solenoid valve 501, U-shaped infusion pipe 500 is opened, allowing the raw materials stored in the corresponding collection tank 503 to flow into U-shaped infusion pipe 500 through main pipe 502 in sequence, and then into hollow cavity 202 through U-shaped infusion pipe 500. The injected material solution flows downward along hollow cavity 202, flows into connecting cavity 601 through the bottom drainage channel 2011, and finally fills all drainage channels 2011 inside each stirring rod 201. Subsequently, the piston 401 is pushed downward by the electric push rod 400, causing the lower half of the hollow cavity 202 to continuously contract. The material solution inside the cavity is compressed by the piston 401, resulting in a rapid increase in internal pressure and the formation of a high-pressure impact liquid column. Under the continuous action of the high-pressure hydraulic pressure, the limiting block 700 at the end of the stirring rod 201 is quickly forced open. The limiting block 700, under pressure, causes the spring 701 to undergo elastic deformation, opening the opening of the drainage channel 2011. At this time, the pressurized material solution can be ejected at high speed from the end of the stirring rod 201 and evenly pressed into the reaction vessel 100. In the reaction raw material system of the reactor, since the stirring rod 201 is evenly arranged vertically inside the reactor 100, the material can be sprayed out simultaneously from different heights inside the reactor. This allows the new raw material to be fully mixed with the existing material in the reactor, achieving layered and uniform feeding of the material, greatly improving the uniformity of material mixing, thereby effectively accelerating the organic synthesis reaction rate and ensuring the full progress of the corrosion inhibitor synthesis reaction. Moreover, this feeding structure is integrated inside the stirring structure, eliminating the need for additional feeding components, saving space inside the reactor and not affecting the stirring operation. It is simple, reasonable, and has good performance.

[0028] like Figure 4 , Figures 6-8 and Figure 10 As shown, the power assembly includes: The positioning post 800 is installed through the bottom end of the fixed post 200. The top end of the positioning post 800 is located in the hollow cavity 202 and is provided with an elastic head 801. The bottom end of the positioning post 800 is located outside the fixed post 200 and is provided with a protrusion 802. The bottom side of the protrusion 802 and several shovel plates 804 are rotatably connected by a connecting rod 803 through a rotating shaft.

[0029] As piston 401 moves downward to compress the material solution in the chamber, the increased pressure inside the chamber acts on the positioning column 800 at the bottom of the hollow cavity 202. The positioning column 800 drives the protrusion 802 to move downward, and through the connecting rod 803, it drives multiple sets of shovels 804 to flip upward simultaneously, causing the shovels 804 to scrape upward along the spherical bottom of the vessel. Because the pressure relief spray at the end of the stirring rod 201 is relatively weak in the early stage, when piston 401 presses down against the positioning column 800, it can forcefully push it downward, causing multiple sets of shovels 804 to move fully, thereby turning up and dispersing the material deposited at the bottom of the vessel. When piston 401 descends to its lowest point, the material solution in the drainage channel 2011 stops being pressurized and depressurized, causing the limiting block 700 to be quickly pulled back to its original position, resealing the outlet end of the drainage channel 2011. Subsequently, as piston 401 continues to rise and reset, the space in the lower half of the hollow chamber continues to increase, forming a negative pressure. This negative pressure further compresses the limiting block 700 against the outlet end of the drainage channel 2011, enhancing the sealing effect. Under this negative pressure, the air in the connecting cavity 601 and each drainage channel 2011 is smoothly extracted and emptied, making the feeding of material into the hollow cavity 202 by the U-shaped infusion tube 500 smoother and unobstructed, quickly completing the filling of the flow channel, avoiding air blockage, and ensuring that the material is fully and adequately filled. At the same time, the positioning column 800 returns to its original position under negative pressure, thereby driving multiple sets of shovels 804 to fall back simultaneously, disturbing the material at the bottom of the vessel again and further improving the overall mixing reaction effect.

[0030] It is worth noting that the location where the positioning post 800 penetrates the bottom end of the fixing post 200 can be sealed using a sliding sealing structure, which is a conventional technical method in this field, and therefore has not been described in detail.

[0031] In one specific embodiment of the present invention, a support rod 900 is detachably connected to the middle of the bottom side of the protrusion 802, and a crushing blade 901 is provided at the bottom end of the support rod 900; a threaded head 9001 is provided at the top end of the support rod 900, and a threaded groove 8021 matching the threaded head 9001 is provided on the bottom side of the protrusion 802. When the positioning column 800 moves downward, it can drive the support rod 900 to move downward through the protrusion 802, so that the support rod 900 drives the crushing blade 901 to extend to the discharge port position at the bottom of the vessel. As the stirring structure rotates as a whole, the crushing blade 901 can rotate synchronously, so that it can cut and break up the condensed and agglomerated material at the discharge port, thereby avoiding the accumulation of material and blocking the discharge channel, and ensuring smooth discharge. The crushing blade 901 can also be reset and raised as the positioning column 800 returns to its original position, so as not to affect the subsequent normal discharge operation. At the same time, the crushing blade 901 can be quickly disassembled and assembled by the screw-fitting of the threaded head 9001 and the threaded groove 8021, which is convenient for replacement and maintenance.

[0032] Working principle and process: The fixed column 200 is driven to rotate by the drive mechanism, which in turn drives multiple sets of stirring rods 201 to rotate inside the reactor 100. This allows the mixture inside the reactor 100 to be stirred and mixed. The raw materials stored in the corresponding collection tank 503 are injected into the hollow cavity 202 through the main pipeline 502 and the U-shaped infusion pipe 500, and can flow into the connecting cavity 601 through the lowest drainage channel 2011, and then fill the drainage channels 2011 inside each stirring rod 201. The piston 401 is driven to move downward, causing the lower half of the hollow cavity 202 to continuously contract. The internal pressure of the material solution inside the cavity increases rapidly after being squeezed by the piston 401, forming a high-pressure impact liquid column. This column quickly opens the opening of the drainage channel 2011 at the end of the stirring rod 201, allowing the pressurized material solution to be ejected at high speed from the end of the stirring rod 201 and evenly pressed into the reaction raw material system inside the reactor 100. Since the stirring rod 201 is evenly arranged vertically up and down along the inside of the reactor 100, the material can be ejected synchronously from different height positions inside the reactor. Furthermore, as the pressure inside the cavity increases, it can act on the positioning column 800 at the bottom of the hollow cavity 202. As the piston 401 presses down and touches the positioning column 800, multiple sets of shovels 804 can simultaneously flip upwards, turning up and breaking up the material deposited at the bottom of the vessel. At the same time, the positioning column 800 moves downwards through the support rod 900, driving the crushing blade 901 to extend towards the discharge port at the bottom of the vessel. With the overall rotation of the stirring structure, the crushing blade 901 can rotate synchronously, enabling it to cut and break up the condensed and agglomerated material at the discharge port. The piston 401 is driven to rise and reset, and the space in the lower hollow chamber continues to increase to form a negative pressure. The negative pressure further makes the limiting block 700 fit tightly against the outlet end of the drainage channel 2011, strengthening the sealing effect. At the same time, the positioning column 800 returns to its original position under the action of negative pressure, thereby driving multiple sets of shovels 804 to fall back synchronously, disturbing the material at the bottom of the vessel again, and further improving the overall mixing reaction effect.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
