Description

Technical Field

[0001] This utility model relates to the technical field of reaction vessels, specifically to an environmentally friendly corrosion inhibitor reaction vessel with temperature control function. Background Technology

[0002] Copper corrosion inhibitors can adsorb onto metal surfaces and form a thin film, protecting copper and other metals from corrosion by the atmosphere and harmful media. In the production of copper corrosion inhibitors, operators need to add different raw materials to a reaction vessel for processing to produce the inhibitor.

[0003] According to Chinese Patent No. CN 219580321 U, a high-efficiency and environmentally friendly copper corrosion inhibitor reactor is disclosed. The reactor includes a reactor body, a first stirring shaft, and a second stirring shaft, both rotatably connected within the reactor body. The reactor body is equipped with a drive assembly for controlling the first and second stirring shafts to rotate in opposite directions. This drive assembly controls the first and second stirring shafts to rotate in opposite directions, which in turn drives corresponding blades to rotate in opposite directions, creating opposing planes between the raw materials. This accelerates the mixing speed of the raw materials, thereby improving the efficiency of the reactor in producing copper corrosion inhibitors.

[0004] This device controls the first and second stirring shafts to rotate in opposite directions via a drive assembly, thereby controlling the upper and lower blades to rotate in opposite directions to accelerate the mixing of raw materials. However, this setup causes stratification at the junction of the upper and lower blades, making it difficult for materials at the bottom of the reactor to move to the top, or vice versa, resulting in uneven mixing of the raw materials. At the same time, existing reactors for corrosion inhibitors have relatively limited functionality, and the mixing of some special raw materials for corrosion inhibitors is affected by environmental temperature and other conditions. Maintaining a constant temperature also affects the final mixing quality. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the problem that in the existing reaction vessel, the stirring blades are arranged vertically and rotate in opposite directions, and the junction of the blades will produce stratification, making it difficult for the material at the bottom of the reaction vessel to move to the top, or the material at the top to move to the bottom, thus making it difficult for the raw materials to be mixed evenly.

[0006] The technical solution adopted to solve the above technical problems is: An environmentally friendly corrosion inhibitor reactor with temperature control function includes a reaction vessel and an outer shaft rotatably installed inside it. An inner shaft is rotatably connected to the inner shaft. A first stirring blade is connected to the outer wall of the outer shaft. An insulation box is connected to the outer wall of the reaction vessel. A transmission mechanism that controls their opposite rotation is connected above the outer shaft and the inner shaft. Second stirring blades are staggered on the outer walls of the first stirring blades. A transmission assembly is connected to one side of the outer shaft to control the second stirring blades at both ends to rotate simultaneously. The first stirring blade and the two second stirring blades are respectively provided with feeding augers at their lower ends for conveying the bottom material to the upper part during stirring.

[0007] As a preferred technical solution of this utility model, the middle feeding auger is fixedly installed on the inner shaft, and the interior of the second stirring blades on both sides is equipped with driven shafts. The feeding augers on both sides are respectively fixedly installed below the corresponding driven shaft wall. The upper ends of the two driven shafts penetrate the reaction tank and extend upwards. The two driven shafts are connected to the transmission assembly.

[0008] As a preferred embodiment of the present invention, the transmission mechanism includes a first bevel gear fixedly installed on the upper walls of the corresponding outer shaft and inner shaft, a second bevel gear meshing with one side of the two first bevel gears, a drive motor connected to one side of the second bevel gear, and the drive motor fixedly connected to the top of the reaction vessel.

[0009] As a preferred embodiment of the present invention, the transmission assembly includes two rotating driven wheels that are respectively fixedly installed on the upper end of the corresponding driven shaft. Both rotating driven wheels are connected to a transmission master wheel via a transmission belt. Both transmission master wheels are fixedly installed above the outer shaft wall.

[0010] As a preferred embodiment of this utility model, the top of the first bevel gear is rotatably connected to a mounting platform, which is fixedly installed on the top of the reaction vessel.

[0011] As a preferred embodiment of this utility model, the spiral blades on the multiple feeding augers are all inclined downwards, and the inclination angle of the multiple spiral blades is 0°-6°.

[0012] As a preferred embodiment of this utility model, the inner shaft and the two driven shafts are each connected to a third stirring blade below the corresponding feeding auger.

[0013] As a preferred embodiment of this utility model, the reaction vessel further includes a feed pipe and a dispensing pipe fixedly installed on its top. An input pipe and an output pipe are respectively connected to the upper and lower sides of the outer wall of the insulation box. A temperature-conducting plate is connected to the inner wall of the insulation box on the side close to the reaction vessel. The insulation box also includes an electric heating tube disposed on the lower side of its inner wall. A controller for controlling the automatic operation of the electric heating tube is provided on the outer wall of the insulation box. The electric heating tube and the controller are electrically connected to realize automated control.

[0014] The beneficial effects of this utility model are as follows: 1. This utility model completely solves the defects of existing technology, such as the formation of stratification at the interface and the inability of bottom material to rise, by using a three-stage coupled stirring system of counter-rotating outer and inner shafts, combined with double-sided second stirring blades and bottom feeding auger. The outer and inner shafts rotate in opposite directions under the drive of the bevel gear set, so that the first and second stirring blades form a high-speed shearing zone in the radial direction. The driven shafts on both sides synchronously draw out the power of the outer shaft, driving their respective feeding augers to continuously lift the solid-liquid mixture deposited at the bottom of the tank to the liquid surface, and then be horizontally thrown by the second stirring blades to achieve full circulation in the vertical direction. 2. Meanwhile, the integrated insulation box outside the reaction tank forms a closed-loop temperature control channel with the electric heating tube through the temperature guide plate. The controller automatically adjusts the heating power according to the preset temperature curve to ensure that the temperature fluctuation during the synthesis of corrosion inhibitor is less than ±1℃. Compared with the traditional intermittent temperature adjustment method that relies solely on jacketed hot water or steam, this solution has a faster response and lower energy consumption. It can also share a drive source with the stirring system, has a compact structure, and is easy to maintain, meeting the stringent requirements of environmentally friendly corrosion inhibitors for constant temperature, energy saving, and high-efficiency production. The 0°-6° micro-tilt helix angle not only ensures the efficiency of material lifting, but also allows the material to be self-emptied by gravity when the machine stops, avoiding residue.

[0022] Example 1 exist Figures 1-4 In this invention, a technical solution is provided: an environmentally friendly corrosion inhibitor reactor with temperature control function, including a reaction tank 1 and an outer shaft 3 rotatably installed inside it. An inner shaft 4 is rotatably connected inside the outer shaft 3. A first stirring blade 5 is connected to the outer side wall of the outer shaft 3. An insulation box 2 is connected to the outer wall of the reaction tank 1. A transmission mechanism that controls their opposite rotation is connected above the outer shaft 3 and the inner shaft 4. Second stirring blades 8 are staggered on the outer side wall of the first stirring blade 5. A transmission component is connected to one side of the outer shaft 3 to control the second stirring blades 8 at both ends to rotate simultaneously. The first stirring blade 5 and the two second stirring blades 8 are respectively provided with feeding augers 6 at their lower ends for conveying the bottom material to the upper part during stirring.

[0023] In one aspect of this embodiment, the intermediate feeding auger 6 is fixedly installed on the inner shaft 4, and driven shafts 7 are installed inside the second stirring blades 8 on both sides. The feeding augers 6 on both sides are fixedly installed below the shaft wall of the corresponding driven shaft 7. The upper ends of the two driven shafts 7 penetrate the reaction tank 1 and extend upward. The two driven shafts 7 are connected to the transmission assembly. At the same time, the two driven shafts 7 are rotatably installed inside the reaction tank 1 and rotate together with the transmission assembly.

[0024] In one aspect of this embodiment, the transmission mechanism includes a first bevel gear 9 fixedly mounted on the upper walls of the corresponding outer shaft 3 and inner shaft 4, a second bevel gear 10 meshing with one side of the two first bevel gears 9, a drive motor 11 connected to one side of the second bevel gear 10, the drive motor 11 fixedly connected to the top of the reaction vessel 1, and a mounting platform 15 rotatably connected to the top of the upper first bevel gear 9, the mounting platform 15 being fixedly mounted on the top of the reaction vessel 1. The transmission assembly includes two rotating driven wheels 13 fixedly mounted on the upper ends of corresponding driven shafts 7. Both rotating driven wheels 13 are connected to a transmission master wheel 12 via a transmission belt 14. Both transmission master wheels 12 are fixedly mounted above the shaft wall of the outer shaft 3. The first bevel gear 9 and the second bevel gear 10 are controlled to rotate together by the drive motor 11 in the transmission mechanism, thereby controlling the outer shaft 3 and the inner shaft 4 to rotate in opposite directions. The outer shaft 3 rotates under the control of the first bevel gear 9, which drives the transmission master wheel 12 and the transmission belt 14 to control the rotating driven wheels 13 on both sides to rotate together, thereby realizing that the second stirring blades 8 on both sides rotate together. In conjunction with the feeding auger 6 connected at the bottom, the uniformity of material mixing is further improved.

[0025] In one aspect of this embodiment, the spiral blades on the multiple feeding augers 6 are all inclined downwards, and the inclination angle of the multiple spiral blades is 0°-6°. By setting the spiral blades to be inclined, the blades can transport the bottom material to the top for mixing during the mixing process, preventing uneven mixing due to layering. At the same time, after the mixing is completed, it is easy for the raw material to slide down, thereby improving the discharge rate.

[0026] In one aspect of this embodiment, the inner shaft 4 and the two driven shafts 7 are each connected to a third stirring blade 16 below the corresponding feeding auger 6. The third stirring blade 16 can further stir the raw materials that are being conveyed from the bottom, making the raw materials in the tank more uniformly stirred.

[0027] In one aspect of this embodiment, the reaction vessel 1 further includes a feed pipe 20 and a dispensing pipe 21 fixedly installed on its top. An input pipe 22 and an output pipe 23 are respectively connected to the upper and lower sides of the outer wall of the insulation box 2. A temperature-conducting plate 19 is connected to the inner wall of the insulation box 2 on the side close to the reaction vessel 1. Before processing, raw materials and reaction raw materials are added through the feed pipe 20 and the dispensing pipe 21 respectively. At the same time, the insulation box 2 is usually equipped with a heat-insulating medium, which can be liquid or gas. It is used in conjunction with the electric heating tube 17 for constant temperature control. The input pipe 22 and the output pipe 23 are used for subsequent replacement of the internal medium. The heat preservation box 2 also includes an electric heating tube 17 disposed on the lower part of its inner wall. The outer wall of the heat preservation box 2 is provided with a controller 18 for controlling the automatic operation of the electric heating tube 17. The electric heating tube 17 and the controller 18 are electrically connected to realize the automatic control of the temperature environment of the stirring inside the reaction vessel 1. According to the actual needs, the controller 18 controls the electric heating tube 17 to keep the mixing temperature constant.

[0028] The working principle of this utility model is as follows: All electrical equipment in this device is powered by an external power source. During use, the raw materials first enter the reaction tank 1 quantitatively through the feed pipe 20 and the dispensing pipe 21. At the same time, according to actual needs, the electric heating tube 17 is activated by the controller 18 to rapidly heat the medium in the insulation box 2 through the temperature guide plate 19 and maintain the set temperature ±1℃. Simultaneously, the drive motor 11 meshes with the first bevel gears 9 on both sides through the second bevel gear 10, causing the outer shaft 3 and the inner shaft 4 to rotate in opposite directions: the outer shaft 3 drives the first stirring blade 5 to perform high-speed clockwise shearing, and the inner shaft 4 drives the central feeding auger 6 to rotate counterclockwise, forming a strong longitudinal circulation. Two sets of transmission main wheels 12 fixed at the upper end of the outer shaft 3 synchronously drive the driven shafts 7 on both sides through the transmission belt 14, so that the second stirring blades 8 and the third stirring blades 16 arranged in opposite directions rotate in the same direction, and perform secondary shearing on the circumferential material. The feeding auger 6 with an inclination angle of 0°-6° continuously lifts the bottom sediment particles to the liquid surface during rotation, and is then horizontally thrown by the first stirring blades 5 rotating in the opposite direction, generating three-dimensional turbulence with the material falling from top to bottom; the third stirring blades 16 synchronously sweep the bottom of the tank to prevent dead corners. The outer wall insulation box 2 continuously replenishes or replaces the medium through the input pipe 22 and the output pipe 23 to ensure that the heat of reaction is absorbed or replenished in time. Once the temperature-sensitive corrosion inhibitor reaches the set viscosity and reactivity, the controller 18 reduces the heating power, the motor 11 slows down, and the tilting spiral blades are automatically emptied under gravity. The product is then completely discharged through the bottom valve, completing an efficient, constant-temperature, residue-free, and environmentally friendly preparation process.
