Abstract
Description
Technical Field
[0001] This utility model relates to the field of corrosion inhibitor production technology, specifically a feeding mechanism for the production of nitrogen heterocyclic corrosion inhibitors. Background Technology
[0002] Nitrogen heterocyclic corrosion inhibitors are organic compounds that form a dense protective film on the metal surface through the chemical adsorption of some atoms in the molecule, thereby inhibiting corrosion reactions. Their mechanism of action mainly relies on the electronic conjugation effect of the heterocyclic structure and the coordination ability of lone pairs of electrons. They exhibit excellent corrosion inhibition performance, especially in acidic, high-temperature, and high-salt environments, with an inhibition efficiency of over 90%. These corrosion inhibitors are widely used in petrochemical, marine environments, acid pickling processes, and drilling fluids, for example, to protect metal equipment from carbon dioxide corrosion in oil and gas extraction, or to prevent corrosion of metals and alloys in seawater media.
[0003] In the specific preparation process, when mixing materials with solvents, in order to ensure the uniformity of the mixture, the materials are usually ground into powder before being added to the solvent. However, when powdered materials are added to the solvent, due to their light weight, some of the powder tends to float on the surface of the solvent, resulting in uneven mixing between the materials and the solvent. This affects the uniformity of the reaction system and the reaction efficiency, and adversely impacts the formation and performance of the target product. Utility Model Content
[0004] The purpose of this invention is to provide a feeding mechanism for the production of nitrogen heterocyclic corrosion inhibitors, so as to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution.
[0006] A feeding mechanism for the production of nitrogen heterocyclic corrosion inhibitors includes a mixing tank, a storage tank, a compaction feeding module, and a mixing mechanism. The mixing tank is fixed on a frame, the storage tank is fixed on top of the mixing tank, and the discharge port at the bottom of the storage tank extends through into the mixing tank. The compaction feeding module is located at the discharge port and is used to compress solid powder materials into cake-shaped materials before feeding them into the mixing tank. The mixing mechanism is located inside the mixing tank and is used to mix the materials.
[0007] Preferably, the mixing mechanism is off-center relative to the mixing tank to form a vertically extending material dropping area between one side of the mixing mechanism and the inner wall of the mixing tank, where the cake-shaped material falls into the material dropping area from the material dropping port.
[0008] Preferably, the compaction feeding module includes a sphere, a push plate, and a cover plate. The sphere is installed in the discharge port with the same diameter and can rotate and adjust within the discharge port. The sphere is provided with a discharge cavity. The push plate is installed in the discharge cavity and can slide and adjust within the discharge cavity. A cover plate is installed at the bottom of the discharge port to seal the bottom port of the discharge port. The cover plate can swing open and close.
[0009] Preferably, a shaft is fixed on the outer wall of the sphere, the shaft extends horizontally through to the outside of the mixing tank, a drive motor is fixed on the outer wall of the mixing tank, and the output shaft of the drive motor is fixed to the end of the shaft.
[0010] Preferably, the inner end wall of the material discharge chamber has an installation cavity, and a first telescopic cylinder that is perpendicular to the shaft is fixed in the installation cavity. The telescopic end of the first telescopic cylinder extends into the interior and is fixed to the push plate.
[0011] Preferably, a U-shaped seat is fixed on the outer wall of the discharge port, a rotating shaft is rotatably mounted on the U-shaped seat, an L-shaped connecting arm and a transmission gear are fixedly mounted on the rotating shaft, a cover plate is fixed on the L-shaped connecting arm, a mounting frame is fixed on the outer wall of the discharge port, a vertically extending second telescopic cylinder is fixed on the mounting frame, and a rack is vertically fixed on the telescopic end of the second telescopic cylinder, the rack meshing with the transmission gear.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows.
[0013] This preparation device uses a first telescopic cylinder to drive a pusher plate to pre-compact the powder in the feeding chamber to form a cake structure. The cake material sinks vertically to the bottom of the solvent under the action of gravity, avoiding the aggregation of liquid mud caused by powder floating.
[0014] The material drop zone formed by the eccentric stirring mechanism creates a transition interface between laminar and turbulent flow with the bulk solvent. As the cake gradually dissolves, it disperses with the stirring flow, improving mixing uniformity and reaction efficiency.
[0015] When the cover is flipped open to the tilted position, its lower end tilts towards the material drop area, allowing the cake-shaped material to slide down along the cover into the drop area. This prevents the mixing components from directly contacting and impacting the material, which could cause the cake to break into powder. Instead, the material is kept in block form and gradually sinks into the solvent and disperses and dissolves. Attached Figure Description

Therefore, they should not be construed as limitations on the embodiments of this utility model.
[0033] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0036] Please see Figures 1-13 This utility model provides a feeding mechanism for the production of nitrogen heterocyclic corrosion inhibitors, including a mixing tank 2, a storage tank 3, a compaction feeding module 4, and a mixing mechanism 5. The mixing tank 2 is fixed on the frame 1, and the storage tank 3 is fixed on the top of the mixing tank 2. The discharge port 31 at the bottom of the storage tank 3 extends through into the mixing tank 2. The storage tank 3 serves as a solid material feeding part, into which fixed powder material is fed. The powder material can then fall into the mixing tank 2 through the discharge port 31. Furthermore, the mixing tank 2 is also equipped with a liquid feeding port (not shown in the figure) for feeding liquid materials. The structure and operating principle of the liquid feeding port are consistent with those in the prior art, and will not be described in detail here. Additionally, as... Figure 3 As shown, the bottom of the mixing tank 2 also has a discharge port 32 for discharging the reaction liquid, and an electric valve 321 is installed on the discharge port 32 to control the discharge flow.
[0037] like Figures 2-6 As shown, the compaction feeding module 4 is located at the discharge port 31. The compaction feeding module 4 includes a ball 41, a push plate 42 and a cover plate 46. The ball 41 is installed in the discharge port 31 with the same diameter, that is, the outer diameter of the ball 41 is adapted to the inner diameter of the discharge port 31.
[0038] A shaft 44 is fixed on the outer wall of the sphere 41. The shaft 44 extends horizontally through the outside of the mixing tank 2. A drive motor 45 is fixed on the outer wall of the mixing tank 2. The output shaft of the drive motor 45 is fixed to the end of the shaft 44. The sphere 41 is provided with a material discharge chamber 411. The inner end wall of the material discharge chamber 411 has an installation cavity 412. A first telescopic cylinder 43 that is perpendicular to the shaft 44 is fixed in the installation cavity 412. When the drive motor 45 works, its output shaft can drive the sphere 41 to rotate and adjust under the connection of the shaft 44. During the rotation of the sphere 41, when the opening of the sphere 41 rotates to the upward position, the material in the storage tank 3 can fall into the material discharge chamber 411. As the sphere 41 continues to rotate, when the opening of the material discharge chamber 411 is downward, the material in it can fall into the mixing tank 2 from the lower end of the discharge port 31.
[0039] The push plate 42 is installed in the material discharge chamber 411 and fixed to the telescopic end of the first telescopic cylinder 43. That is, the push plate 42 slides against the inner wall of the material discharge chamber 411. By telescopically working the first telescopic cylinder 43, the push plate 42 can be moved in the material discharge chamber 411, thereby adjusting the size of the space in the material discharge chamber 411 for temporarily storing materials. In addition, a cover plate 46 is installed at the bottom of the material discharge port 31 to seal the bottom port of the material discharge port 31. The cover plate 46 can swing open and close.
[0040] When the cover plate 46 is closed and the material falls into the discharge chamber 411, rotate the adjusting ball 41 until the opening of the discharge chamber 411 faces downward. Then, the first telescopic cylinder 43 extends and pushes the push plate 42 toward the port of the discharge chamber 411. Under the blocking action of the cover plate 46, the powdered material temporarily stored in the discharge chamber 411 can be compacted into a cake shape. Subsequently, the cover plate 46 is rotated open, and the first telescopic cylinder 43 continues to extend and push the cake-shaped material out of the discharge chamber 411 and fall into the solvent in the mixing tank 2 through the bottom opening of the discharge port 31.
[0041] The powdered material is compacted into a cake shape and added to the solvent to increase the material density. The cake-shaped material can sink into the solvent, avoiding uneven mixing caused by the powder floating. In addition, the cake structure sinks and gradually disperses and dissolves in the solvent, ensuring that the material is evenly distributed in the solvent. Furthermore, the gradual dispersion and dissolution of the cake makes the concentration gradient of the reaction system tend to be balanced, thereby effectively improving the quality of the target product.
[0042] In addition, by extending and retracting the first telescopic cylinder 43, the push plate 42 can be moved and adjusted accordingly, thereby adjusting the space for temporary materials in the material discharge chamber 411 to achieve quantitative feeding of different amounts of materials.
[0043] Secondly, when the first telescopic cylinder 43 extends to its limit position, it pushes the push plate 42 to move to the port of the discharge chamber 411, blocking the port of the discharge chamber 411, which can prevent materials from entering the discharge chamber 411 and stop feeding.
[0044] like Figure 2 and Figure 6 As shown, the stirring mechanism 5 is located inside the mixing tank 2 and is used to stir the mixed materials to improve the reaction quality. The stirring mechanism 5 is set off-axis relative to the mixing tank 2, that is, the stirring mechanism 5 is inside the mixing tank 2 and deviates to one side of the mixing tank 2, thereby forming a vertically extending material drop area 21 between one side of the stirring mechanism 5 and the inner wall of the mixing tank 2. That is, the stirring part in the stirring mechanism 5 will not directly enter the material drop area 21.
[0045] like Figure 6 As shown, when the cover plate 46 is flipped open to the tilted state, its lower end tilts towards the material drop area 21, and the cake-shaped material can slide down along the cover plate 46 into the material drop area 21, avoiding the direct contact and impact of the stirring component on the material, which would cause the cake to break into powder, thereby maintaining the material in a block form and gradually sinking into the solvent and dissolving it.
[0046] This design can utilize the density characteristics of the cake itself to ensure that it sinks stably to the bottom of the frame 1, and can also reduce the damage to the shape of the cake material by external mechanical force, and avoid the powder generated after crushing from floating or locally agglomerating on the liquid surface.
[0047] In addition, after the material falls into the material drop zone 21, it gradually dissolves and disperses. Combined with the stirring action of the stirring mechanism 5, the solvent flows continuously, and the dissolved and dispersed material is stirred in a wave-like manner, forming an orderly dispersion process from the edge to the center, which significantly improves the uniformity of the material distribution in the solvent.
[0048] Combination Figure 4 and Figure 5A A U-shaped seat 461 is fixed on the outer wall of the discharge port 31. A rotating shaft 462 is rotatably mounted on the U-shaped seat 461. An L-shaped connecting arm 463 and a transmission gear 464 are fixedly mounted on the rotating shaft 462. A cover plate 46 is fixed on the L-shaped connecting arm 463. A mounting bracket 465 is fixed on the outer wall of the discharge port 31. A vertically extending second telescopic cylinder 466 is fixed on the mounting bracket 465. A rack 467 is vertically fixed at the telescopic end of the second telescopic cylinder 466. The rack 467 meshes with the transmission gear 464.
[0049] The cover plate 46 is hinged and installed using a U-shaped seat 461, a rotating shaft 462 and an L-shaped connecting arm 463. The second telescopic cylinder 466 extends and retracts, which drives the rack 467 to move accordingly. The moving rack 467 meshes with the drive gear 464 and drives the rotating shaft 462 to rotate. Under the connection of the L-shaped connecting arm 463, the cover plate 46 can be adjusted to swing open and close. Example 2
[0050] Please see Figure 2 , Figure 3 as well as Figures 7 to 11 The difference between this embodiment and Embodiment 1 is that:
[0051] The stirring mechanism 5 includes a rectangular frame 51, a first stirring rod 53 and a second stirring rod 54. A suspension 501 is fixed on the inner wall of the stirring tank 2. A stirring main shaft 52 is rotatably mounted through the suspension 501. The rectangular frame 51 is fixed on the bottom end of the stirring main shaft 52. Several first stirring rods 53 and second stirring rods 54 are evenly distributed on the rectangular frame 51. A bevel gear A521 is fixed at the top end of the stirring main shaft 52. A bevel gear B522 is fixedly fitted on the shaft 44. The bevel gear B522 meshes with the bevel gear A521.
[0052] During the rotation of shaft 44, bevel gear B522 can be driven to rotate. The rotating bevel gear B522 meshes with and drives bevel gear A521, which in turn drives the stirring shaft 52 to rotate, thereby driving the rectangular frame 51 to rotate. The first stirring rod 53 and the second stirring rod 54 follow the rotation of the rectangular frame 51, realizing the stirring of materials and solvents. Through the linkage of bevel gear A521 and bevel gear B522, the rotational force of the drive motor 45 driving shaft 44 is converted into the rotational force of the rectangular frame 51, without the need to set up an additional drive source for the stirring mechanism 5.
[0053] Among them, a shaft 55 is rotatably mounted on the rectangular frame 51 at the top and bottom respectively. A belt 56 that can rotate around the two shafts 55 is sleeved on the two shafts 55 through the limiting guide wheel 551 fixed on them. The first stirring rod 53 is evenly mounted on the belt 56, that is, the first stirring rod 53 is evenly distributed on the belt 56. The second stirring rod 54 is evenly distributed on both sides of the rectangular frame 51. There are two belts 56.
[0054] A linkage shaft 57 is vertically fixed on the bottom wall of the mixing tank 2. The linkage shaft 57 passes through the bottom of the rectangular frame 51 and is arranged coaxially with the mixing main shaft 52. The linkage shaft 57 is rotatably connected to the rectangular frame 51. A bevel gear C58 is fixed on the top of the linkage shaft 57, and a bevel gear D59 is fixedly fitted on the shaft body 55 below. The bevel gear D59 meshes with the bevel gear C58.
[0055] During the rotation of the rectangular frame 51, due to the fixed arrangement of the bevel gear C58 and the linkage shaft 57, the bevel gear D59 and the bevel gear C58 mesh and drive the bevel gear D59 in the opposite direction and drive the shaft 55 below to rotate, thereby driving the belt 56 to run around the two shafts 55. The belt 56 drives each first stirring rod 53 to move up and down in sequence, realizing a dynamic stirring mechanism in both horizontal and vertical directions, effectively reducing material sedimentation and further improving the quality of the mixing reaction.
[0056] Furthermore, the operation of belt 56 relies on the meshing transmission of bevel gears C58 and D59, eliminating the need for an additional drive source. Example 3
[0057] Please see Figure 9 and Figure 10 The difference between this embodiment and Embodiment 2 is that:
[0058] U-shaped frames 531 are evenly distributed on the belt 56. A rotating rod 533 is rotatably installed in the mounting hole 532 on the U-shaped frame 531. A spiral spring 534 is sleeved on the outside of the rotating rod 533. One end of the spiral spring 534 is fixed to the inner wall of the mounting hole 532, and the other end is fixed to the outer wall of the rotating rod 533. The tail of the first stirring rod 53 is fixedly sleeved on the rotating rod 533.
[0059] Under the elastic restraint of the spiral spring 534, the first stirring rod 53 is set perpendicular to the surface of the belt 56. During stirring, as the belt 56 moves, the first stirring rod 53 will come into contact with the rectangular frame 51. When the first stirring rod 53 is squeezed by the rectangular frame 51, the first stirring rod 53 will overcome the elastic force of the spiral spring 534 and swing to avoid motion interference. After the first stirring rod 53 separates from the rectangular frame 51, the elastic force of the spiral spring 534 can drive the first stirring rod 53 to gradually return to its original position. The overall structure layout is reasonable.
[0060] In addition, the restraining force provided by the spiral spring 534 to the first stirring rod 53 is greater than the resistance of the solvent to the first stirring rod 53. That is, during stirring, the first stirring rod 53 will not swing due to the resistance of the solvent, thus ensuring the stable maintenance of the stirring state of the first stirring rod 53.
[0061] The rectangular frame 51 has a vertically penetrating spherical cavity 511 on its upper and lower sides, corresponding to the position of the first stirring rod 53. Each spherical cavity 511 is fitted with a rolling ball 512. The rolling ball 512 is in contact and squeezed with the first stirring rod 53. That is, the first stirring rod 53 directly contacts and squeezes the rolling ball 512. During the process of the first stirring rod 53 being pressed and gradually swinging, the rolling ball 512 rolls, reducing the friction between it and the first stirring rod 53, and ensuring that the belt 56 can run smoothly and stably. Example 4
[0062] A significant amount of heat is generated in the later stages of the reaction. Excessive heat accumulation in stirred tank 2 can have adverse effects. To address the heat dissipation issue in the later stages of the reaction, please refer to [link to relevant documentation]. Figure 1 , Figure 2 , Figure 6 and Figure 12 The difference between this embodiment and embodiment 3 is as follows:
[0063] It also includes a heat dissipation mechanism, which includes a coil 6 and a water-cooled box 61. The coil 6 is fixed on the inner wall of the mixing tank 2 and is spirally distributed around the axis of the mixing tank 2. The water-cooled box 61 is mounted on the frame 1 and located on one side of the mixing tank 2. The outlet of the coil 6 is connected to the inlet of the water-cooled box 61, and the inlet of the coil 6 is connected to the outlet of the water-cooled box 61.
[0064] A temperature sensor 91 is fixed on the inner wall of the mixing tank 2. An electrical control box 9 is provided on the frame 1. The temperature sensor 91 is electrically connected to the control module in the electrical control box 9. The temperature sensor 91 monitors the temperature inside the mixing tank 2. When the temperature inside the mixing tank 2 is too high, the electrical control box 9 controls the water pump in the water cooling box 61 to work, drawing the cooling medium in the coil 6 into the water cooling box 61. At the same time, the cooling medium in the water cooling box 61 flows back to the coil 6, realizing the circulation of the cooling medium.
[0065] When the cooling medium flows in the coil 6, it can absorb the temperature generated by the reaction in the stirred tank 2. After the cooling medium flows into the water-cooled box 61, it undergoes heat exchange and cooling, and then flows back to the coil 6. This cycle of cooling ensures that the temperature in the stirred tank 2 remains stable.
[0066] Among them, the coil 6 is arranged in a spiral shape to ensure a large coverage area for cooling and temperature reduction in the mixing tank 2, thereby improving the cooling and temperature reduction efficiency.
[0067] Secondly, it also includes three-way valves A62 and B63. An electric heating box 7 is installed on the frame 1 on one side of the water-cooled box 61. The outlet of the electric heating box 7 is connected to the first port of the three-way valve B63 through the connecting pipe C71. The second port of the three-way valve B63 is connected to the outlet of the water-cooled box 61 through the connecting pipe B67. The third port of the three-way valve B63 is connected to the inlet of the coil 6 through the inlet pipe 65. The inlet of the electric heating box 7 is connected to the first port of the three-way valve A62 through the connecting pipe D72. The second port of the three-way valve A62 is connected to the inlet of the water-cooled box 61 through the connecting pipe A66. The third port of the three-way valve A62 is connected to the outlet of the coil 6 through the outlet pipe 64.
[0068] Since heating is required in the initial stage of the reaction, the three-way valve A62 is adjusted so that the outlet pipe 64 is only connected to the connecting pipe D72, and the three-way valve B63 is adjusted so that the inlet pipe 65 is only connected to the connecting pipe C71. The water pump in the electric heating box 7 operates to draw the cooling medium in the coil 6 into the electric heating box 7 through the outlet pipe 64 and the connecting pipe D72 in sequence. The electric heater in the electric heating box 7 heats the cooling medium. The heated cooling medium is then discharged into the coil 6 through the connecting pipe C71 and the inlet pipe 65. This process can heat the initial stage of the reaction.
[0069] After heating is complete, as the reaction continues, the generated heat gradually accumulates, providing the heat required for subsequent reactions. Especially when the generated heat is greater than the actual need, there is no need to use the electric heating box 7 for heating. Adjust the three-way valve A62 so that the outlet pipe 64 is connected only to the connecting pipe A66, and adjust the three-way valve B63 so that the inlet pipe 65 is connected only to the connecting pipe B67. At this time, the heat dissipation mechanism can be used to dissipate the excess heat.
[0070] In addition, the outlet pipe 64 is U-shaped and has two spiral sections 641. The two spiral sections 641 are arranged symmetrically on the left and right and extend vertically. A vertically penetrating rectangular cover 8 is fixed on the outer wall of the frame 1. The two spiral sections 641 are matched and installed inside the rectangular cover 8. A cooling fan 81 is installed on one side of the rectangular cover 8. When cooling and heat dissipation are performed, the cooling fan 81 works to draw outside air into the rectangular cover 8, so that a positive pressure is formed inside the rectangular cover 8. Since the upper and lower ends of the rectangular cover 8 are penetrating, the air inside the rectangular cover 8 is discharged from both ends of the rectangular cover 8, forming a flowing airflow that can carry away some of the heat in the outlet pipe 64. Before the cooling medium enters the water cooling box 61, pre-heat dissipation can be performed to accelerate the cooling of the medium and improve the cooling efficiency of the medium.
[0071] In addition, the outlet pipe 64 has two spiral sections 641, and both spiral sections 641 are located inside the rectangular cover 8. The spiral sections 641 extend the travel of the cooling medium inside the rectangular cover 8, making it contact the airflow for a longer time and with a larger contact area, thereby further improving the preheating and cooling efficiency of the medium.
[0072] In addition, the cooling medium is used for both heating the reaction inside the mixing tank 2 and cooling down the heat generated later, achieving two goals at once. At the same time, heating and heat dissipation basically share the same piping system, which optimizes the system structure and improves the compactness and integration of the equipment. Example 5
[0073] Please see Figure 5B The difference between this embodiment and embodiment 3 is as follows:
[0074] The diameter of the mounting cavity 412 is slightly smaller than that of the discharge cavity 411. Several through sliding holes 421 are evenly distributed around the axis of the push plate 42. A forming rod 422 is slidably inserted into each sliding hole 421. One end of each forming rod 422 is fixed to the inner end wall of the mounting cavity 412. When the ball 41 rotates to the point where the port of the discharge cavity 411 faces directly downward and the cover plate 46 closes to seal the bottom of the discharge port 31, the ends of each forming rod 422 abut against and fit against the cover plate 46.
[0075] When the port of the discharge chamber 411 is facing upward, the powder will fall into the discharge chamber 411 and be distributed in places other than the forming rod 422;
[0076] During the powder compaction process, as the first telescopic cylinder 43 extends, it pushes the push plate 42 toward the side of the cover plate 46. The push plate 42 slides along the forming rod 422, eventually compacting the powder into a cake. The forming rod 422 forms multiple through holes on the cake-shaped material.
[0077] When the cake-shaped material is added to the solvent, its porous structure increases the contact area with the solvent, thereby accelerating the dissolution and dispersion of the cake structure and improving the dispersion and mixing efficiency.
[0078] In addition, it is worth noting that the first telescopic cylinder 43 and the second telescopic cylinder 466 in this application are electric push cylinders.
[0079] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Therefore, this utility model will not explain the control method and circuit connection in detail.
[0080] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
