Abstract

The present invention relates to the technical field of chemical equipment, and specifically to a preparation kettle for an efficient fluoride ion removing agent and an operation method thereof, comprising a reactor and a stirring assembly, wherein the stirring assembly comprises a planetary gear, a moving frame, a moving groove, a spring, at least two stirring shafts, a transverse plate, an anchor blade, axial flow blades corresponding to the number of the stirring shafts, radial flow blades corresponding to the number of the stirring shafts, at least two inclined plates, a sliding plate and a motor. During the stirring process, the axial flow blades can push the material to move along the axial direction of the stirring shaft, and the radial flow blades can cause the material to flow in the radial direction.

The stirring assembly drives the moving frame through the planetary gear, thereby causing the stirring shaft to slide in the planetary gear.

Description

Technical Field

[0001] The invention relates to the technical field of chemical equipment, in particular to a preparation kettle for a high-efficiency fluoride ion removing agent and an operating method thereof. Background Art

[0002] As we all know, defluoridation agents include liquid defluoridation agents and solid defluoridation agents. They are deep defluoridation agents developed based on the characteristics of wastewater from various industries. The so-called deep defluoridation refers to a series of continuous treatment methods based on the characteristics of fluoride-containing wastewater based on conventional purification treatment, aiming to improve the effluent quality and utilization level.

[0003] In the preparation process of high-efficiency fluoride ion removers, there are many deficiencies in the existing patent technologies. For example, in the Chinese patent publication number CN222057207U, "A new type of defluorination agent production device", the above-mentioned comparative patent uses a stirring rod as the core driving component, and a stirring plate is fixed on the stirring rod. When working, the motor drives the stirring rod to make a single rotational motion, and the stirring plate rotates accordingly. The force applied to the material is mainly the shear force in the circumferential direction, which makes the material move mainly on a circular path, lacking effective axial and radial mixing, and difficult to disperse and blend in all directions and in depth. For example, in a larger reactor, this single circular motion is easy to form a "blind spot" for material mixing on the reactor wall and the central area, resulting in uneven mixing. Although automatic cleaning can be achieved, the stirring method is single, and it is difficult to achieve an ideal mixing effect for high-viscosity raw materials, affecting the performance of the remover.

[0013] A method for operating a preparation kettle for a fluoride ion efficient removing agent, comprising:

[0014] S1: Slowly add the weighed raw materials into the reactor in sequence through the feed port on the top of the reactor. Be careful not to spill the raw materials during the addition process, and pay attention to the amount of raw materials added to ensure that it meets the formula requirements;

[0015] S2: Turn on the motor, the motor drives the stirring shaft to rotate, and then the anchor blade, axial flow blade and radial flow blade start to work. The anchor blade fits the bottom of the reactor, which can effectively stir the bottom raw materials and prevent the raw materials from settling at the bottom. The axial flow blade makes the material flow in the axial direction to promote the mixing of the upper and lower materials. The radial flow blade is located at the top of the stirring shaft, which makes the material flow in the radial direction to enhance the mixing effect of the materials. According to the characteristics of the raw materials and the reaction requirements, the motor speed is adjusted to achieve the appropriate stirring intensity. The radial flow blade drives the sliding plate to rotate while rotating. When the sliding plate fits the inclined plate, the sliding plate moves upward and drives the stirring shaft to move upward at the same time. The movement of the stirring shaft drives the sliding of the cross plate, and the sliding of the cross plate drives the spring to contract. When the sliding plate and the inclined plate are no longer in contact, the elastic potential energy of the spring drives the stirring shaft to reset, thereby further improving the stirring efficiency and the mixing effect of the materials.

[0016] S3: During the stirring process, impurities in the raw materials will contact the impurity filtering assembly as the materials flow. The first screen, the second screen and the third screen have gradually smaller filter holes from top to bottom, and the impurities can be filtered in multiple stages. Large particles of impurities are first intercepted by the first screen, and smaller particles of impurities are intercepted by the second screen and the third screen in turn, thereby ensuring the purity of the reaction materials;

[0017] S4: The gas generated during the reaction is collected through a gas collection pipe, which is connected to the inside of the reactor and can effectively collect various gases generated by the reaction. The collected gas enters the gas purification device for purification to remove harmful components and avoid pollution to the environment. The pressure gauge is installed on the top of the gas purification device to monitor the pressure in the gas purification device in real time to ensure the safe operation of the equipment. If the pressure is abnormal, it is necessary to adjust or stop the reaction in time and check the equipment;

[0018] S4: according to the temperature required for the reaction, the heater is started, the heater transfers heat to the heating tube, the heating tube heats the outer jacket of the reactor, and thus the temperature of the material in the reactor is increased;

[0019] S5: Slowly open the valve on the side of the discharge pipe, and the prepared high-efficiency fluoride ion remover flows out through the discharge pipe.

[0020] (III) Beneficial effects

[0021] The preparation kettle for high-efficiency fluoride ion removal agent and its operation method, the preparation kettle is provided with axial flow blades and radial flow blades, during the stirring process, the axial flow blades can push the material to move along the axial direction of the stirring shaft, and the radial flow blades make the material flow in the radial direction. This multi-directional material flow, compared with the single circumferential direction shear force in the patent, can make the material fully mixed in the axial, radial and circumferential directions, effectively avoid the formation of material mixing "blind spots" on the wall and central area of ​​the reactor, so that the material is dispersed and blended in all directions and in depth, the stirring component drives the moving frame through the planetary gear, and then the stirring shaft slides in the planetary gear. This structure allows the stirring shaft to move to a certain position while performing a circular motion, further enriches the stirring path, and enhances the uniformity of material mixing in a larger reaction. In the reactor, it can better cover various areas and improve the mixing effect. The anchor blade at the bottom of the middle stirring shaft fits with the bottom of the reactor. During the stirring process, the anchor blade can scrape and stir the material at the bottom of the reactor. For high-viscosity raw materials, it can effectively break the accumulation and agglomeration that may exist at the bottom, prompt high-viscosity materials to participate in the mixing, and improve the overall mixing effect. It makes up for the deficiency of the single stirring method in the comparative patent that is difficult to handle high-viscosity raw materials, and is beneficial to improving the performance of the high-efficiency fluoride ion remover. The inclined plate arranged in the reactor and the sliding plate slidingly arranged on the top of the outer radial flow blade and fitting with the inclined plate, during the stirring process, the sliding plate will slide on the inclined plate as the radial flow blade rotates, further disrupting the flow path of the material, making the material mixing in the local area more sufficient, and improving the overall mixing quality.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 11 A preparation kettle for a high-efficiency fluoride ion removing agent comprises a reaction kettle 1 and a stirring component 2, wherein the stirring component 2 is installed on the reaction kettle 1.

[0036] The stirring assembly 2 includes a planetary gear 21, a moving frame 22, a moving groove 23, a spring 24, at least two stirring shafts 3, a transverse plate 25, an anchor blade 5, axial flow blades 6 corresponding to the number of stirring shafts 3, radial flow blades 7 corresponding to the number of stirring shafts 3, at least two inclined plates 26, a sliding plate 27 and a motor 4.

[0037] In the above embodiments, refer to Figure 1 , Figures 5 to 8The planetary gear 21 is fixedly arranged on the top of the reactor 1. As a key component of the transmission of the stirring assembly 2, it not only provides an installation position for the moving frame 22, but also drives other components connected to it to move through its own rotation under the drive of the motor 4, so as to realize the linkage stirring of multiple stirring shafts 3. The moving frame 22 is fixed at the bottom of the planetary gear 21, and a moving groove 23 is provided inside the moving frame 22. The moving frame 22 plays the role of carrying and guiding the movement of other components, and provides a track for the sliding of the cross plate 25 in the moving groove 23. The moving groove 23 is provided in the moving frame 22, and provides a holding space for the spring 24 and the cross plate 25, and limits the moving direction of the cross plate 25, so that the cross plate 25 can slide in a specific direction in the moving groove 23. One end of the spring 24 is fixed to the top of the moving groove 23. The spring 24 is used to provide elastic support for the cross plate 25, so that the stirring shaft 3 has elastic space to move up and down within a certain range, which helps the stirring shaft 3 to adapt to different states of the materials in the reactor 1 and enhance the stirring effect. At least two stirring shafts 3 are slidably arranged in the planetary gear 21. In this embodiment, four stirring shafts 3 are used. The stirring shaft 3 serves as a mounting carrier for the paddles. It rotates under the drive of the planetary gear 21 and can slide up and down in the planetary gear 21. The arrangement of multiple stirring shafts 3 can expand the stirring range and improve the uniformity of material stirring. Each cross plate 25 is fixed to the top of the corresponding stirring shaft 3 and is slidably arranged with the moving groove 23. The cross plate 25 connects the stirring shaft 3 with the spring 24, and the stirring shaft 3 is connected to the moving groove 23. The elastic force of the transfer spring 24 and the sliding fit in the moving groove 23 ensure that the stirring shaft 3 moves up and down smoothly in the planetary gear 21. The anchor blade 5 is fixed at the bottom of the stirring shaft 3 in the middle and fits with the bottom of the reactor 1. The anchor blade 5 can fully stir the material at the bottom of the reactor 1 to prevent the material from settling at the bottom, ensuring that the bottom material and the material in other parts are fully mixed. The axial flow blade 6 corresponds to the number of the stirring shaft 3 and is located at the top of the anchor blade 5. When the stirring shaft 3 rotates, the axial flow blade 6 pushes the material to flow in the axial direction, so that the material forms an up and down circulation flow in the reactor 1, thereby enhancing the mixing effect of the material in the vertical direction. The radial flow blade 7 corresponds to the number of the stirring shaft 3 and is fixed at the top of the stirring shaft 3. During operation, the material forms a radial flow around the stirring shaft 3, diffuses the material from the center of the stirring shaft 3 to the surroundings, improves the dispersion of the material in the horizontal direction, and further improves the uniformity of material mixing. At least two inclined plates 26 are evenly fixed in the reactor 1. In this embodiment, four inclined plates 26 are used. The inclined plates 26 change the flow direction of the material and cooperate with the sliding plates 27 to further promote the mixing and flow of the material and optimize the stirring effect. The sliding plates 27 are slidably arranged on the top of the radial flow blades 7 located on the outside and fit with the inclined plates 26. The sliding plates 27 move under the drive of the radial flow blades 7 and interact with the inclined plates 26 to guide the flow of the material, enhance the complex flow pattern of the material in the reactor 1, and improve the stirring efficiency. The motor 4 is installed on the top of the reactor 1.Its output shaft is fixedly arranged with the planetary gear 21. The motor 4 serves as the power source of the stirring assembly 2, converting electrical energy into mechanical energy, and driving the planetary gear 21 to rotate through the output shaft, thereby driving the entire stirring assembly 2 to work.

[0038] First, see Figure 4 In this embodiment, an impurity filtering assembly 8 is also included. The impurity filtering assembly 8 is installed on the stirring assembly 2. The impurity filtering assembly 8 includes a first screen 9, a second screen 10 and a third screen 11.

[0039] In the above embodiment, the first screen 9 is fixedly arranged on the top of the stirring shaft 3. During the material stirring process, it is at a higher position. First, the larger particle impurities in the material are intercepted. Due to its upper position, relatively larger particle impurities can be preliminarily screened out to prevent these large particle impurities from affecting the reaction effect or causing damage to other components during the subsequent stirring process. The second screen 10 is fixedly arranged on the stirring shaft 3 and is located below the first screen 9. The material after the preliminary filtration by the first screen 9 will continue to flow downward to contact the second screen 10. The filter mesh hole of the second screen 10 is smaller than that of the first screen 9, and can further filter out impurities with a slightly smaller size, perform secondary screening on the material, and improve the purity of the material. The third screen 11 is fixedly arranged at the bottom of the stirring shaft 3 and is located below the second screen 10. As the last filtering checkpoint, the filter mesh hole of the third screen 11 is the smallest. It screens the material filtered by the first two screens again, intercepts the remaining fine impurities as much as possible, and ensures that the material treated by the impurity filtering device reaches a higher purity requirement and meets the quality standard for the preparation of the fluoride ion efficient removal agent.

[0040] Then, see Figure 1 In this embodiment, a gas processing assembly 12 is also included. The gas processing assembly 12 is installed on the top of the reactor 1. The gas processing assembly 12 includes a gas collecting pipe 13, a gas purification device 14 and a pressure gauge 15.

[0041] In the above embodiment, the gas collecting pipe 13 is fixed on the top of the reactor 1 and communicated with the inside of the reactor 1. Its function is to collect the gas generated during the reaction process in the reactor 1 and guide the gas to subsequent processing equipment. The gas purification device 14 is installed on the top of the gas collecting pipe 13 and is responsible for purifying the collected gas to remove impurities and harmful components that may be contained therein so that the discharged gas meets the relevant standards. The pressure gauge 15 is installed on the top of the gas purification device 14 and is used to monitor the gas pressure after being processed by the purification device in real time, and provide pressure data for the operator so as to timely grasp the gas processing situation and the pressure status in the reactor 1.

[0042] Second, see Figure 2In this embodiment, a discharge assembly 16 is also included. The discharge assembly 16 is installed at the bottom of the reaction kettle 1. The discharge assembly 16 includes a discharge pipe 17 and a valve 18.

[0043] In the above embodiment, the discharge pipe 17 is fixedly arranged at the bottom of the reactor 1, serving as a channel for the material to flow out of the reactor 1 after the reaction is completed, and the prepared high-efficiency fluoride ion removing agent is transported to the next link. The valve 18 is installed on the side of the discharge pipe 17, and the discharge speed and flow rate of the material are adjusted by controlling the opening and closing of the valve 18 to realize the control of the discharge process.

[0044] Again, see Figures 9 to 11 In this embodiment, a heating tube 19 and a heater 20 are also included.

[0045] In the above embodiment, the reactor 1 adopts a double-layer jacket structure, which provides installation space for the heating tube 19 and helps to better maintain the temperature environment required for the reaction. The heating tube 19 is fixedly arranged in the outer jacket of the reactor 1, and heat is transferred by the flow of the heat transfer medium in the heating tube 19, so that the material in the reactor 1 reaches and is maintained at a suitable reaction temperature. The heater 20 is fixedly arranged at the bottom of the reactor 1 and is connected to the heating tube 19. The heater 20 serves as a heating source to provide heat for the heating tube 19. After startup, the heater 20 converts electrical energy or other energy into thermal energy, which is transferred to the material in the reactor 1 through the heating tube 19, thereby meeting the heating requirements in the preparation process of the high-efficiency fluoride ion removing agent.

[0046] Finally, see Figure 1 and Figure 4 In this embodiment, it also includes an arc groove 28, a baffle 29 and a round handle 30.

[0047] In the above embodiment, the arc groove 28 is opened on the top of the reactor 1, which provides a sliding track of a specific shape for the baffle 29, limits the moving path of the baffle 29, and enables the baffle 29 to slide on the top of the reactor 1 along the arc track. The arc design may be related to the structure of the top of the reactor 1 or specific operation requirements. The baffle 29 is slidably set in the arc groove 28, and the bottom of the baffle 29 is slidably set with the reactor 1. The sliding of the baffle 29 in the arc groove 28 can achieve the shielding or opening of a specific area on the top of the reactor 1. The baffle 29 can flexibly adjust the opening state of the top of the reactor 1 according to the needs of the preparation process, for example, when it is necessary to add materials, observe or prevent debris from entering, etc., to play a corresponding role. The round handle 30 is fixedly arranged on the side of the baffle 29, which provides an operator with a position that is easy to hold and operate, so that the operator can easily push or pull the baffle 29 by holding the round handle 30 to make it slide in the arc groove 28, thereby realizing the control of the top opening of the reactor 1 and improving the convenience of operation.

[0048] Working principle:

[0049] The preparation kettle for the fluoride ion efficient removal agent and the operation method thereof, firstly, a worker slowly adds weighed raw materials into the reactor 1 in sequence through the feed port at the top of the reactor 1. During the adding process, care is taken to avoid spilling the raw materials, and at the same time, the amount of raw materials added is observed to ensure that it meets the formula requirements.

[0050] Then the worker turns on the motor 4, which drives the stirring shaft 3 to rotate, and then the anchor blade 5, the axial flow blade 6 and the radial flow blade 7 start working. The anchor blade 5 fits the bottom of the reactor 1, which can effectively stir the bottom raw materials and prevent the raw materials from settling at the bottom. The axial flow blade 6 makes the material flow in the axial direction to promote the mixing of the upper and lower materials. The radial flow blade 7 is located at the top of the stirring shaft 3, which makes the material flow in the radial direction to enhance the mixing effect of the materials. According to the raw material characteristics and reaction requirements, the speed of the motor 4 is adjusted to achieve a suitable stirring intensity. The radial flow blade 7 rotates and drives the sliding plate 27 to rotate. When the sliding plate 27 fits with the inclined plate 26, the sliding plate 27 moves upward and drives the stirring shaft 3 to move upward at the same time. The movement of the stirring shaft 3 drives the cross plate 25 to slide, and the sliding of the cross plate 25 drives the spring 24 to contract. When the sliding plate 27 and the inclined plate 26 are released from the state of being fitted, the elastic potential energy of the spring 24 drives the stirring shaft 3 to reset, thereby further improving the stirring efficiency and the mixing effect of the materials.

[0051] During the stirring process, impurities in the raw materials will contact the impurity filtering component 8 as the material flows. The holes of the first screen 9, the second screen 10 and the third screen 11 gradually decrease from top to bottom, and the impurities can be filtered in multiple stages. Large particles of impurities are first intercepted by the first screen 9, and smaller particles of impurities are intercepted by the second screen 10 and the third screen 11 in turn, thereby ensuring the purity of the reaction materials.

[0052] The gas generated during the reaction is collected through a gas collecting pipe 13. The gas collecting pipe 13 is connected to the inside of the reactor 1 and can effectively collect various gases generated by the reaction. The collected gas enters a gas purification device 14 for purification to remove harmful components therein and avoid pollution to the environment. A pressure gauge 15 is installed on the top of the gas purification device 14 to monitor the pressure in the gas purification device 14 in real time to ensure the safe operation of the equipment. If the pressure is abnormal, it is necessary to adjust or stop the reaction in time and check the equipment.

[0053] According to the temperature required for the reaction, the heater 20 is started, and the heater 20 transfers heat to the heating tube 19, and the heating tube 19 heats the outer jacket of the reactor 1, thereby raising the temperature of the material in the reactor 1.

[0054] Finally, the worker slowly opens the valve 18 on the side of the discharge pipe 17 , and the prepared fluoride ion high-efficiency removing agent flows out through the discharge pipe 17 .

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
