Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical preparation equipment technology, and in particular to a preparation device for a high-temperature corrosion inhibitor for acidification. Background Technology
[0002] High-temperature corrosion inhibitors are substances that can prevent initiation corrosion and crevice corrosion by forming a protective film on the metal surface, isolating the substrate from corrosion by the medium. They belong to the category of corrosion inhibitors. The corrosion inhibitor forms a strong passivation film on the metal surface, thereby slowing down the corrosion rate of the metal. In this way, the corrosion inhibitor reduces the metal's corrosion tendency and can effectively prevent localized excessive dissolution of the metal (i.e., pitting corrosion).
[0003] Existing equipment for preparing high-temperature corrosion inhibitors for acidification generally has a simple structure, consisting of a cylindrical body with an internal stirring shaft. The stirring shaft is rotated by a motor to mix the internal liquid. However, many chemical production equipment has a large cylindrical body, and the stirring tracks of the internal stirring shaft or stirring blades are relatively simple. Some liquids cannot be fully mixed, resulting in problems with the quality of the processed product and affecting industrial production.
[0004] Therefore, based on customer feedback regarding the shortcomings of the existing device, the inventors made further improvements to overcome the aforementioned problems. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for preparing a high-temperature corrosion inhibitor for acidification that avoids single stirring, has multiple stirring trajectories, and can fully mix the liquid.
[0006] The purpose of this utility model is achieved through the following technical solution: a device for preparing a high-temperature corrosion inhibitor for acidification, comprising an outer cylinder, a rotating cylinder, and a moving plate;
[0007] The outer cylinder is fixed by a mounting base, and the rotating cylinder is rotatably installed inside the outer cylinder. The rotating cylinder and the outer cylinder are coaxially arranged. Multiple short stirring columns are opened on the side wall of the rotating cylinder, and multiple through holes are distributed on the side wall of the rotating cylinder. The bottom of the rotating cylinder is connected to a central shaft, which passes through the bottom surface of the outer cylinder and its extended end is connected to the output shaft of motor A.
[0008] The upper surface of the outer cylinder is open, and the movable plate is inserted into the rotating cylinder from top to bottom through the upper surface opening of the outer cylinder. The top end of the movable plate is connected to the pushing component, and the pushing component is fixed to the upper part of the mounting base. A motor B is provided at the top end of the movable plate, and the movable plate is driven to rotate by the motor B.
[0009] During operation, the raw material liquid is first poured into the outer cylinder through the upper opening of the outer cylinder, while the inner cylinder is driven to rotate. The stirring column agitates the raw material, and the pushing component is activated to move the moving plate in the inner cylinder. At this time, motor B drives the moving plate to rotate, so that the moving plate rotates while moving, thus fully mixing and stirring the raw material.
[0010] As a preferred technical solution of this application, the bottom surface of the rotating cylinder is provided with multiple triangular through holes at equal intervals around the circumference, which facilitates the flow of the original liquid between the rotating cylinder and the outer cylinder during stirring.
[0011] As a preferred technical solution of this application, the stirring short columns on the side wall of the rotating cylinder include inner short columns and outer short columns; the inner and outer short columns are respectively opened on the inner and outer surfaces of the side wall of the rotating cylinder, and multiple stirring short columns are opened at equal intervals from top to bottom along the rotating cylinder.
[0012] As a preferred technical solution of this application, the multiple through holes on the rotating cylinder are opened between two adjacent stirring short columns, and the through holes enable the interior of the rotating cylinder to communicate with the inner side of the outer cylinder.
[0013] As a preferred technical solution of this application, the pushing component is an electric push rod, which includes a motor C and a push rod; the left side of the motor C is fixed to the mounting base, and its right side is connected to the push rod. The push rod is arranged parallel to the upper surface of the outer cylinder, and the bottom end of the push rod is perpendicularly connected to the upper end of the moving plate. The motor C is driven to move the push rod, thereby driving the moving plate to move left and right inside the rotating cylinder.
[0014] As a preferred technical solution of this application, the upper end of the movable plate is provided with a mounting plate, the mounting plate is connected to the bottom end of the push rod, and the upper end of the movable plate passes through the mounting plate and is connected to the motor B.
[0015] As a preferred technical solution of this application, the movable plate is a rectangular thin plate, and the edge of the movable plate is an arc-shaped edge.
[0016] As a preferred technical solution of this application, the mounting base includes mounting rings and rollers; multiple mounting rings are vertically arranged on one side of the mounting base, the outer cylinder is adapted to be inserted into the mounting rings and fixed to the mounting base by the mounting rings, and a roller is installed at each of the four corners of the bottom surface of the mounting base to move the device.
[0017] This utility model has the following advantages:
[0018] (1) It can thoroughly stir and mix liquids;
[0019] Currently, many mixing devices used in chemical production often need to mix a large amount of liquid at once, thus requiring a large cylinder. During the mixing process, some liquid is not fully mixed. This solution sets up a rotatable rotating cylinder in the outer cylinder, and short stirring columns are set on both the inner and outer sides of the rotating cylinder. When the rotating cylinder rotates, the short columns on the inner and outer sides simultaneously stir the liquid, increasing the stirring force and fully mixing the original liquid.
[0020] (2) Avoid simple stirring and use varied stirring trajectories;
[0021] Currently, many mixing devices used in chemical production adopt a cylindrical structure. The raw liquid to be mixed is poured into the cylinder, and a stirring shaft controlled by a motor is installed inside the cylinder. The stirring trajectory of the stirring shaft is singular, and the liquid cannot be fully mixed, which reduces the working efficiency. This solution is equipped with a moving plate. The moving plate is controlled by a pushing component and motor B to move left and right while rotating itself, making the stirring trajectory of this device more varied. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.
[0032] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0033] Therefore, based on the above issues, please refer to Figure 1 This invention proposes a device for preparing a high-temperature corrosion inhibitor for acidification to solve the problem.
[0034] (Example)
[0035] See Figures 1 to 7 The present embodiment proposes a preparation device for a high-temperature corrosion inhibitor for acidification, which includes an outer cylinder 3, a rotating cylinder 4 and a moving plate 5;
[0036] Among them, see Figure 1 and Figure 2 The outer cylinder 3 is suspended on the ground by the mounting ring of the mounting base 1, and a rotatable rotating cylinder 4 is installed in the outer cylinder 3. The rotating cylinder 4 is coaxial with the outer cylinder 3, and a central shaft is vertically connected to the bottom of the rotating cylinder 4. The central shaft passes through the bottom surface of the outer cylinder 3 and is connected to the motor A6, which drives the rotating cylinder 4 to rotate.
[0037] Among them, see Figure 2 and Figure 3 Multiple short stirring columns are provided on the side wall of the rotating cylinder 4. When the rotating cylinder 4 is rotated, the short stirring columns agitate the liquid. At the same time, multiple through holes 10 are provided on the side wall of the rotating cylinder 4. The through holes 10 penetrate the inner side of the rotating cylinder 4 and the inner side of the outer cylinder 3 to facilitate the flow and mixing of the liquid.
[0038] Among them, see Figure 2 and Figure 4 The movable plate 5 is inserted inside the rotating cylinder 4. The top end of the movable plate 5 extends upward from the rotating cylinder 4 and reaches above the opening on the upper surface of the outer cylinder 3. The top end of the movable plate 5 is connected to the pushing component 8. The pushing component 8 is installed at the upper part of the mounting base 1. At the same time, the top end of the movable plate 5 is connected to a motor B9, which can drive the movable plate 5 to rotate.
[0039] During stirring, the raw material liquid is first poured into the cylinder through the opening on the upper surface of the outer cylinder 3. Then, the driving motor A6 makes the rotating cylinder 4 rotate. Both the stirring column and the rotating cylinder 4 itself stir and mix the liquid. At this time, the driving push component 8 is driven to make the moving plate 5 move inside the rotating cylinder to further mix it. At the same time, the driving motor B9 makes the moving plate 5 rotate. The movement is both horizontal and self-rotation, which increases the stirring trajectory and promotes the mixing of the liquid.
[0040] Existing preparation devices generally have a simple structure, with a cylindrical shape and a stirring shaft inside. The stirring shaft is controlled by a motor to rotate and mix the liquid. However, many chemical industry production devices have a large shell volume, and the stirring trajectory of the internal stirring shaft or stirring blades is relatively simple, resulting in some liquids not being fully mixed and reducing work efficiency. This solution designs a preparation device with a rotatable rotating cylinder 4 inside an outer cylinder 3. Multiple short stirring columns are installed on the side of the rotating cylinder 4. When the rotating cylinder 4 rotates, both the short stirring columns and the rotating cylinder 4 itself will stir the liquid, which can evenly mix the raw materials in a relatively large cylinder. At the same time, a moving plate 5 is provided. The moving plate 5 is controlled by a pushing component 8 and a motor B9, so that the moving plate 5 can move left and right while rotating itself, resulting in a varied stirring trajectory, which facilitates the thorough mixing of the liquid.
[0041] In this embodiment, see Figures 2-5 For the rotating cylinder 4, there is a sleeve structure between the rotating cylinder 4 and the outer cylinder 3. The rotating cylinder 4 is set inside the outer cylinder 3 and is coaxial with the sleeve. The bottom surface of the rotating cylinder 4 is provided with multiple triangular through holes at equal intervals around the circumference, which facilitates the uniform flow of the original liquid from the gap between the rotating cylinder 4 and the outer cylinder 3 and effectively mixes the liquid. At the same time, the stirring short columns on the side wall of the rotating cylinder 4 include inner short columns 11 and outer short columns 12. The inner short column 11 is opened on the inner side of the side wall of the rotating cylinder 4, and the outer short column 12 is opened on the outer side of the side wall of the rotating cylinder 4. The multiple stirring short columns are arranged at equal intervals from top to bottom along the side wall of the rotating cylinder 4, which can fully stir the liquid in the outer cylinder 3. The multiple through holes 10 on the side wall of the rotating cylinder 4 connect the inner side of the outer cylinder 3 with the interior of the rotating cylinder 4 to avoid obstructing the liquid flow. The multiple through holes 10 are opened between two adjacent stirring short columns on the same horizontal plane, and the through holes 10 and the stirring short columns do not interfere with each other.
[0042] Furthermore, the rotating cylinder 4 is inserted into the outer cylinder 3, and there is a certain distance between the lower surface of the rotating cylinder 4 and the inner side of the bottom surface of the outer cylinder 3 to avoid affecting the flow of liquid. A central shaft is connected to the center of the lower surface of the rotating cylinder 4, and the end of the central shaft penetrates vertically downward through the bottom surface of the outer cylinder 3 and the end protruding is connected to the motor A6.
[0043] In this embodiment, see Figure 2 and Figure 6For the movable plate 5, the movable plate 5 is a rectangular thin plate, and the edge of the movable plate 5 is an arc end, which can effectively avoid wear caused by the collision between the edge and corner of the movable plate 5 and the inner wall of the rotating cylinder 4 when the movable plate 5 rotates, and is more conducive to the stability of the overall device structure. The upper surface of the outer cylinder 3 has a rectangular opening 13. The upper end of the movable plate 5 extends through the rectangular opening 13 and extends to be connected to the push assembly 8. The push assembly 8 drives the movable plate 5 to move back and forth. The push assembly 8 is an electric push rod, which includes a motor C7 and a push rod. The left side of the motor C7 is fixed to the mounting base 1, and the right side of the motor C7 is connected to the push rod. The push rod is set parallel to the upper surface of the outer cylinder 3, and the bottom end of the push rod is perpendicularly connected to the upper end of the movable plate 5. The motor C7 drives the push rod to move, thereby driving the movable plate 5 to move inside the rotating cylinder 4.
[0044] Furthermore, a mounting plate is provided at the upper end of the movable plate 5, the mounting plate is connected to the end of the push rod, and the upper end of the movable plate 5 passes through the mounting plate and is connected to the motor B9, so that the movable plate 5 can rotate by being driven by the motor B9.
[0045] It should be noted that the electric push rod is existing technology, and the push assembly 8 can also use a cylinder mechanism to swing the lead screw to move the moving plate 5.
[0046] It should be noted that the driving and stirring methods in this solution can be combined arbitrarily. Motors A6, B9, and C7 can be started simultaneously, so that the rotating cylinder 4 rotates while cooperating with the moving plate 5 which moves laterally and rotates at the same time. Alternatively, only motors A6 and C7 can be started, so that the moving plate 5 only moves laterally without rotating and stirring. This makes the stirring path of the device more varied and more conducive to mixing liquids.
[0047] In this embodiment, see Figure 1 and Figure 7 For the mounting base 1, the mounting base 1 includes mounting rings and rollers 2. The mounting base 1 is L-shaped. Two mounting rings are provided on one side of the upper part of the mounting base 1. The two mounting rings are coaxially arranged and spaced apart by a certain distance. The outer cylinder 3 can be fitted into the upper and lower mounting rings and fixed. Rollers 2 are provided at the lower part of the mounting base 1. A total of four rollers 2 are respectively arranged at the four corners of the bottom surface of the mounting base 1. The device can be moved by the rollers 2, which facilitates the actual use of this preparation device.
[0048] When stirring the raw materials, first pour the raw materials into the outer cylinder 3 from the opening on the upper surface of the outer cylinder 3 according to the requirements. At the same time, turn on the motor A6 to drive the rotating cylinder 4 to rotate. The space between the rotating cylinder 4 and the outer cylinder 3 is the processing and mixing space of the raw liquid. Then, drive the motor C7 to start the pushing component. The push rod works to make the moving plate 5 move back and forth. At this time, the motor B9 starts to make the moving plate 5 rotate and stir inside the rotating cylinder 4.
[0049] Current mixing devices are typically simple, employing a cylindrical structure. The raw liquid to be mixed is poured into the cylinder, and a motor-controlled stirring shaft is installed inside. However, many mixing devices used in chemical production often require mixing large quantities of liquid at once, necessitating large cylinders. Furthermore, some liquid remains unmixed during stirring, and the shaft's unidirectional stirring trajectory leads to incomplete mixing, reducing efficiency and potentially causing product quality issues that impact industrial production. This solution proposes a preparation device with a rotatable rotating cylinder 4 within an outer cylinder 3. Short stirring columns are located on both the inner and outer sides of the rotating cylinder 4. As the rotating cylinder 4 rotates, these columns simultaneously stir the liquid, increasing the stirring intensity. A movable plate 5, controlled by a pusher assembly 8 and a motor B9, allows the plate to move left and right while rotating, resulting in a varied stirring trajectory and thorough mixing of the raw liquid to obtain a qualified product. Additionally, the device is equipped with rollers 2, facilitating transport to designated locations for preparation.
[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
