Description

Technical Field

[0001] The utility model belongs to the technical field of chemical equipment, and specifically relates to a stirring device for decolorization treatment. Background Art

[0002] The existing calcium chloride solution is commonly decolorized by combining hydrogen peroxide and activated carbon. Due to the strong oxidizing property of hydrogen peroxide and the corrosion characteristics of high chloride ions in the calcium chloride solution, the common decolorization device uses a plastic storage tank for the decolorization reaction. However, at room temperature, the decolorization time of hydrogen peroxide and activated carbon for the calcium chloride solution is long and the effect is not good.

However, the commonly used plastic material tank is not resistant to high temperature, is easy to age, has low strength, is not suitable for stirring and high temperature working conditions, and most plastic storage tanks are standard products, without special protection for high-risk or volatile materials.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0029] Next, in conjunction with the attached Figure 1 to the attached Figure 2 and specific embodiments, the present invention will be elaborated in detail.

[0030] As Figure 1-2 shown, the present invention provides a stirring device for decolorization treatment. This device can use a combination of hydrogen peroxide and activated carbon to decolorize the solution under high-temperature conditions of ≤100°C. The stirring device of this application includes a cylinder body 1. At the top opening of the cylinder body 1, an upper flat head 2 is installed. At the center of the upper flat head 2, a stirring frame 3 is installed. On the stirring frame 3, a power mechanism 4 is installed. On the driving end of the power mechanism 4, a stirring shaft 5 is installed. The stirring shaft 5 passes through the upper flat head 2 and extends into the cylinder body 1. Stirring blades 6 are welded on the stirring shaft 5. The solution in the cylinder body 1 is stirred by the stirring blades 6. In this application, the stirring blades 6 are fixed on the stirring shaft 5 by welding, which can prevent accidents caused by the loosening of the stirring blades 6 due to material corrosion. The number and height of the upper and lower arrangements of the stirring blades 6 in this application are not limited and can be adjusted according to the specific decolorization process. In one embodiment, the stirring blades 6 are provided in two gears. The low-gear stirring blades 6 are between 10% and 40% of the height of the cylinder body 1, and the high-gear stirring blades 6 are between 40% and 80% of the height of the cylinder body 1. Moreover, the form of the stirring blades 6 is a paddle type or a turbine type blade, so as to achieve uniform stirring of the liquid.

[0031] The power mechanism 4 includes a motor and a speed reducer connected to the motor. The driving end of the speed reducer is installed with a stirring shaft 5 through a coupling. Among them, the diameter of the stirring shaft 5 can be adjusted according to the stirring speed, the length of the stirring shaft 5, the length of the stirring blades 6, and the viscosity of the solution. In this application, the diameter of the stirring shaft 5 is designed to be between 6 and 12 cm, which can meet the decolorization requirements. Multiple pipe orifices 7 communicating with the cylinder body 1 are fixed on the upper flat head 2 of this application. Specifically, the upper flat head 2 is provided with orifices corresponding to the pipe orifices 7, and multiple pipe orifices 7 are correspondingly welded on the orifices of the upper flat head 2. The length of the pipe orifice 7 extending upward is 10 - 20 cm. The pipe orifice 7 is used for externally connecting a pipeline. For this purpose, a national standard flange or a quick connector is welded on the pipe orifice 7, or threads are processed to achieve quick and simple connection of the externally connected pipeline. Specifically in this embodiment, multiple pipe orifices 7 at least include a feed port 71 for the material to be decolorized, a hydrogen peroxide feed port 72, and a steam port 73. The feed port 71 for the material to be decolorized is used to add the liquid to be decolorized, such as calcium chloride solution, etc., but not limited to this. The hydrogen peroxide feed port 72 is used to add hydrogen peroxide into the cylinder body 1 to decolorize the liquid to be decolorized. The steam port 73 is used to introduce steam into the cylinder body 1 to heat the solution. By setting the feed port 71 for the material to be decolorized and the hydrogen peroxide feed port 72 on the upper flat head 2 in this application, the requirement of separate feeding is met; at the same time, by setting the steam port 73, heating of the solution is realized, and the decolorization ability is improved.

[0032] Specifically, the cylinder body 1, the upper flat head 2, the stirring shaft 5, the stirring blades 6, and the pipe orifice 7 in this application are all made of metal materials. For example, the cylinder body 1 and the upper flat head 2 can be selected as carbon steel, and the stirring shaft 5, the stirring blades 6, and the pipe orifice 7 can be selected as stainless steel materials. Since the stirring device needs to be produced under high-temperature and corrosive working conditions, and metal materials have the advantages of high temperature resistance, not easy to age, and high strength, etc., they are more suitable for high-temperature working conditions; an anti-corrosion layer is coated on the inner wall surface of the cylinder body 1, the lower surface of the upper flat head 2, the outer wall surface of the stirring shaft 5, the outer wall surface of the stirring blades 6, and the inner wall surface of the pipe orifice 7. The setting of the anti-corrosion layer further enhances the corrosion resistance of the stirring device. Preferably, the anti-corrosion layer is polytetrafluoroethylene with a thickness of 2 - 4 mm. In this way, the decolorization treatment stirring device of this application can not only prevent the liquid from corroding the device, but also meet the production conditions of hydrogen peroxide heating and decolorization.

[0033] Specifically, refer to Figure 2, the multiple pipe orifices 7 further include an emergency cooling spray orifice 74, a sight glass orifice 75, a vent orifice 76, and a manhole 77. Of course, during actual production, other pipe orifices can be set as needed. For example, when it is necessary to use under a pressurized condition, a nitrogen orifice, a pressure gauge orifice, an emergency relief orifice, etc. can be designed, but not limited thereto; in this application, the manhole 77 is a quick-opening manhole, and the quick-opening manhole is used for the installation of internal stirring fittings during the initial use, and during the later production, the internal reaction condition can be observed through this manhole 77, and activated carbon or other solid materials can also be added through this manhole 77. In addition, in this application, the manhole 77 is arranged on the upper flat head 2, which can prevent the liquid from leaking from the side wall of the cylinder body 1. The emergency cooling spray orifice 74 can introduce pure water into the cylinder body when needed to perform emergency cooling on the solution.

[0034] Specifically, refer to Figure 1 , one end of the hydrogen peroxide feed orifice 72 located inside the cylinder body 1 is connected with a liquid inlet guiding pipe 8, and the outlet end of the liquid inlet guiding pipe 8 faces the inner wall of the cylinder body 1. Preferably, the inner lining at the outlet of the liquid inlet guiding pipe 8 is locally thickened by 2 mm to increase the strength of the liquid inlet guiding pipe 8. The liquid inlet guiding pipe 8 is used to guide the hydrogen peroxide to the inner wall of the cylinder body 1, relieve the splashing of the material, reduce the volatilization of the material, and prevent static electricity generated by the friction between the material and the air from causing safety accidents. In some embodiments, the liquid inlet guiding pipe 8 includes a vertical pipe and an inclined pipe, the inclined pipe is connected to the lower end of the vertical pipe, and the inclined pipe is inclined in the direction towards the inner wall of the cylinder body 1, and the outlet of the inclined pipe is close to the inner wall of the cylinder body 1, so that the hydrogen peroxide entering the cylinder body 1 can quickly contact the inner wall of the cylinder body 1 and reduce the friction with the air.

[0035] Specifically, refer to Figure 1 , one end of the steam orifice 73 located inside the cylinder body 1 is connected with a steam internal connection sleeve 9, and the bottom of the steam internal connection sleeve 9 is detachably connected with a steam diffusion pipe 10 by using a flange or other connection means. By separating the steam diffusion pipe 10 from the steam internal connection sleeve 9, it can prevent the accessories contained in the upper flat head 2 from protruding too long, which is easy to be damaged during transportation and increases the installation difficulty. When the steam diffusion pipe 10 is corroded, it can be replaced by removing the part where it is connected to the steam internal connection sleeve 9; the steam diffusion pipe 10 includes a vertical extension pipe 101 and a horizontal extension pipe 102, the vertical extension pipe 101 is connected to the bottom of the steam internal connection sleeve 9, the horizontal extension pipe 102 is connected to the bottom of the vertical extension pipe 101, the horizontal extension pipe 102 extends towards the center of the cylinder body 1, and a plurality of steam diffusion holes are opened on the outer wall of the horizontal extension pipe 102. In this application, the steam internal connection sleeve 9 and the steam diffusion pipe 10 are provided to introduce steam into the cylinder body 1 and directly introduce the steam into the solution through the steam diffusion pipe 10 to heat the solution and improve the decolorization effect of hydrogen peroxide.

[0036] Specifically, a thermometer sleeve port extending into the cylinder body 1 is provided on the outer wall of the middle part of the cylinder body 1. Generally, the thermometer sleeve port extends into the cylinder body 1 by 300 - 500 mm. A thermometer 11 is installed in the thermometer sleeve port, and the thermometer 11 is used to measure the temperature inside the cylinder body 1. It should be noted that a steam pipeline is connected to the steam port 73 of this application, and a steam valve is provided on the steam pipeline. An emergency cooling spray port 74 is connected to an emergency cooling pipeline, and an emergency cooling valve is provided on the emergency cooling pipeline. By interlocking the temperature signal of the thermometer 11 with the steam valve and the emergency cooling valve, the purpose of automatically adjusting the temperature of the solution inside the cylinder body 1 is achieved. In other words, when the thermometer 11 detects that the temperature inside the cylinder body 1 is too high, it transmits the temperature signal to the steam valve. After receiving the signal, the steam valve closes the steam pipeline and simultaneously opens the emergency cooling valve to spray pure water into the cylinder body for emergency cooling. When the thermometer detects that the temperature inside the cylinder body is relatively low, it transmits the temperature signal to the steam valve. After receiving the signal, the steam valve opens the steam pipeline to introduce steam into the cylinder body to heat the liquid.

[0037] Specifically, referring to Figure 1 , a plurality of stirring baffles 12 are circumferentially and spacedly arranged on the inner wall of the cylinder body 1. The stirring baffles 12 are perpendicular to the inner wall of the cylinder body 1, and the stirring baffles 12 are fixedly connected to the inner wall of the cylinder body 1 through reinforcing plates 13. Preferably, four stirring baffles 12 are arranged oppositely in four equal parts inside the cylinder body 1. The stirring baffles 12 are perpendicular to the inner wall of the cylinder body 1, dividing the cylinder body 1 into four equal parts. The stirring baffles 12 are arranged between the stirring blades 6 and the inner wall of the cylinder body 1 to prevent the stirring baffles 12 from affecting the stirring of the stirring blades 6. During the stirring process, the material impacts the stirring baffles 12 following the stirring direction, increasing the radial flow capacity of the material and improving the stirring and mixing effect. The stirring baffles 12 are connected to the inner wall of the cylinder body 1 through the reinforcing plates 13. The reinforcing plates 13 are arranged at multiple intervals up and down along the inner wall of the cylinder body 1, and the stirring baffles 12 are integrally arranged and fixed on the multiple reinforcing plates 13 to enhance the strength of the stirring baffles 12.

[0038] Specifically, a discharge port 14 is provided on the side wall of the bottom of the cylinder body 1. The discharge port 14 is used to discharge the material. A slope plate 15 is inclined at the bottom of the inner cavity of the cylinder body 1. The slope plate 15 is inclined downward towards the discharge port 14. The thickness of the slope plate 15 is 6 - 10 mm, and the slope is 3 - 8°, which is convenient for the material to be discharged from the discharge port 14. The lower part of the slope plate 15 is supported on the bottom of the cylinder body 1 through a support plate 16 to improve the overall strength of the cylinder body 1.

[0039] Specifically, an electrostatic grounding plate 17 is provided on the outer side wall of the bottom of the cylinder body 1 to prevent the cylinder body 1 from working while being charged and causing personal safety accidents.

[0040] Specifically, a cross-shaped channel steel 18 with central symmetry is arranged on the upper surface of the upper flat head 2, and the power mechanism 4 and the stirring frame 3 are installed at the center square-shaped channel steel of the cross-shaped channel steel 18. The cross-shaped channel steel 18 is welded to the upper flat head 2, which can strengthen the strength of the upper flat head 2. A square hole is opened in the upper flat head 2 within the central square-shaped channel steel of the cross-shaped channel steel 18 for installing the stirring shaft 5 and the stirring frame 3. A steel plate is laid on the square-shaped channel steel, and bolt holes are opened on the steel plate according to the bolt orientation of the stirring frame for installing the stirring frame 3. A stirring hole is opened in the center of the steel plate, and the hole diameter is larger than the diameter of the stirring shaft 5 for the stirring shaft 5 to pass through the steel plate. Bolt holes are equidistantly designed near the edge around the upper flat head 2. The top of the cylinder body 1 is turned outwards to form an annular flange, and bolt holes are also equidistantly arranged on the annular flange rope. Then, the upper flat head 2 is installed on the top of the cylinder body 1 through bolts and sealed.

[0041] Specifically, double lifting lugs 19 are symmetrically arranged on the upper flat head 2, which is convenient for installation and hoisting.

[0042] The working principle of this application is as follows:

[0043] Taking the decolorization of calcium chloride solution as an example, first place this device in position. According to the on-site use environment, make a base under this device and install this device on the base. After this device is in position, loosen the connection bolts between the upper flat head 2 and the cylinder body 1, remove the upper flat head 2, put the stirring shaft 5 into the cylinder body 1, then put the upper flat head 2 back. After the upper end of the stirring shaft 5 passes through the central hole of the upper flat head 2, reinstall and fix the upper flat head 2 to the cylinder body 1 with bolts. Then pass the stirring frame 3 through the stirring shaft 5 and install the stirring frame 3 on the reinforcing channel steel of the upper flat head 2 with bolts. After checking the installation orientation of the stirring shaft 5 and the stirring frame 3, connect the motor and the reducer to the stirring shaft 5 through a coupling, and then install and fix the body of the reducer to the stirring frame with bolts.
