Description

Technical Field

[0001] This invention relates to the fields of chemical equipment and environmental protection technology, and in particular to a wastewater treatment reactor for sodium silicate production. Background Technology

[0002] Wastewater treatment chemical reaction vessels are specialized equipment used for the preparation and dissolution of chemical agents in wastewater treatment processes. Through stirring, heating (or cooling), and other functions, they uniformly dissolve and mix solid or liquid agents such as flocculants and coagulants according to specified ratios, forming a directly dosable solution. This equipment is typically a closed container, equipped with a stirring device and a temperature control system, enabling precise control of agent concentration and reaction conditions. This improves agent activity and wastewater treatment efficiency, and it is widely used in the pretreatment or advanced treatment stages of industrial wastewater and municipal sewage treatment, ensuring the stable operation of subsequent purification processes.

[0003] A search revealed Chinese patent publication number CN219792742U, which discloses a wastewater treatment device. This device separates the aqueous phase from the wastewater generated during aniline acetonitrile production through a multi-stage countercurrent extractor and inputs it into an oxidation tank for oxidation treatment before discharge. The organic phase obtained after extraction is distilled to recover the extractant, and the residue from the distillation vessel is used as fuel for incineration in a boiler for harmless treatment. This device is characterized by low energy consumption and a simple treatment process. Furthermore, the boiler allows for the full utilization of the heat from the combustion of organic matter in the wastewater, overcoming the drawbacks of existing aniline acetonitrile production wastewater treatment methods, such as high energy consumption and inefficient energy utilization.

[0004] The aforementioned patent document mentions "low energy consumption and simple processing" in the "Beneficial Effects" section of the specification. While this reduces energy consumption during the reaction of wastewater and solvent and simplifies the process, significant shortcomings exist in actual mixing. When wastewater and solvent react, a large number of bubbles are generated, and the resulting particles easily adhere to these bubbles, forming large composite particles. Lacking an effective treatment mechanism, these large composite particles cannot be promptly and thoroughly broken up, further encapsulating the continuously generated bubbles. This phenomenon severely hinders sufficient contact between wastewater and reagents, significantly reducing the uniformity of material mixing and preventing the reaction from proceeding fully.

[0005] Therefore, a wastewater treatment reactor for sodium silicate production is proposed to address the above problems. Summary of the Invention

[0006] To overcome the above deficiencies, the present invention provides a wastewater treatment reactor for sodium silicate production, which aims to improve the problem in some existing reactors where, during wastewater treatment, the bubbles generated during mixing form large composite particles that cannot be crushed, affecting the sufficiency and uniformity of the reaction, resulting in unstable products, poor treatment effect, and difficulty in meeting emission standards.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A wastewater treatment reactor for sodium silicate production includes a reactor body. A drive transmission assembly is installed at the top of the reactor body. Multiple stirring plates are fixedly connected to the outside of the drive transmission assembly. A vibrating plate is slidably connected inside the stirring plates. Multiple convex balls in contact with the vibrating plates are fixedly connected to the inner wall of the reactor body. Multiple coils are installed outside the drive transmission assembly. Pull ropes are provided outside the coils. A filter screen one is fixedly connected to the other end of the pull rope and rotatably connected to the inner wall of the stirring plates. A filter screen two is rotatably connected to one side of the filter screen one and fixedly connected to the inner wall of the stirring plates.

[0009] As a further description of the above technical solution:

[0010] The drive transmission assembly includes a motor fixedly connected to the top of the vessel body. The bottom of the motor is provided with an outer shaft and an inner shaft, and the inner shaft is rotatably connected to the inner wall of the outer shaft. An outer column is fixedly connected to the bottom of the outer shaft, and an inner column is fixedly connected to the bottom of the inner shaft. A one-way bearing is fixedly connected to the outside of the inner column and rotatably connected to the inner wall of the outer column. A large gear is fixedly connected to the outside of the one-way bearing. Multiple sliding rods are rotatably connected to the inner wall of the outer column. A small gear that meshes with the large gear is fixedly connected to the outside of the sliding rod. The inner wall of the coil is fixedly connected to the outside of the sliding rod.

[0011] As a further description of the above technical solution:

[0012] A limiting plate that slides on the inner wall of the mixing plate is fixedly connected to one side of the vibrating plate. Two sliding columns are fixedly connected to the side of the limiting plate away from the vibrating plate, and the sliding columns are slidably connected to the inner wall of the mixing plate. Two springs are also fixedly connected to the side of the limiting plate away from the vibrating plate, and the other end of the springs is fixedly connected to one side of the inner wall of the mixing plate.

[0013] As a further description of the above technical solution:

[0014] A rotating rod is fixedly connected to the top of the coil, and two balls are fixedly connected to the top of the rotating rod. A sliding sleeve is slidably connected to the outside of the rotating rod, and the balls are slidably connected to the inner wall groove of the sliding sleeve.

[0015] As a further description of the above technical solution:

[0016] The inner wall of the stirring plate is slidably connected to a sealing gasket, and the pull rope is slidably connected to the inner wall of the sealing gasket.

[0017] As a further description of the above technical solution:

[0018] A rubber ring is also fixedly connected to the inner wall of the stirring plate, and the pull rope is slidably connected to the inner wall of the rubber ring.

[0019] As a further description of the above technical solution:

[0020] A feed pipe is fixedly connected to the top of the vessel body, a discharge pipe is fixedly connected to the bottom of the vessel body, and an interception net is fixedly connected to the inner wall of the discharge pipe.

[0021] As a further description of the above technical solution:

[0022] The multiple convex balls are distributed in a multi-layered annular array along the inner wall of the reactor, and their surfaces are coated with a polytetrafluoroethylene anti-stick coating.

[0023] The present invention has the following beneficial effects:

[0024] 1. In this invention, the first and second filter screens form a tight shear fit, which can precisely and thoroughly crush excessively large composite particles generated during the reaction. This ingenious design not only effectively avoids the impact of air bubbles generated during the reaction on reaction efficiency due to their inclusion inside the particles, but also significantly enhances the mixing uniformity between materials, allowing the wastewater and the reagent for purifying sodium silicate to fully contact and react more thoroughly in the reactor, thereby making the resulting product more stable. Through this treatment, the harm of subsequent wastewater discharge to water bodies, soil, and other surrounding environments is greatly reduced, making it easier to meet strict environmental emission standards.

[0025] 2. In this invention, the outer column drives the vibrating plate to rotate synchronously during rotation. When the vibrating plate contacts the convex ball fixed to the inner wall of the vessel, it is squeezed into the interior of the stirring plate. At this time, the inner spring is compressed and generates a strong reaction force. Driven by the reaction force, the vibrating plate can repeatedly strike the inner wall of the vessel. This structural design can effectively prevent wastewater, reagents, and the composite products formed when the two combine from adhering to the inner wall of the vessel. This reduces the manpower and material costs required for cleaning residues and avoids the adhering pollutants from interfering with the subsequent wastewater treatment process, ensuring that the equipment can operate stably for a long time and maintain high-efficiency treatment capacity.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Reference Figures 1 to 9The present invention provides an embodiment of a wastewater treatment reactor for sodium silicate production, comprising a reactor body 1, which is used to contain wastewater to be treated, reagents for purifying sodium silicate, and various working components, providing a reaction space. A drive transmission assembly is installed at the top of the reactor body 1, which can provide power support for the operation of various components of the equipment and realize differentiated linkage. The drive transmission assembly includes a motor 2 fixedly connected to the top of the reactor body 1. The motor 2 serves as a power source and can output rotational power. An outer shaft 3 and an inner shaft 4 are provided at the bottom of the motor 2. The outer shaft 3 can drive the outer column 5 and the stirring assembly to rotate, and the inner shaft 4 drives the inner column 12 and the transmission components to rotate. The two rotate concentrically, but on opposite axes, in the same direction, and the rotational speed of the inner shaft 4 is slightly lower than that of the outer shaft 3, forming a basis for differentiated linkage. The inner shaft 4 is rotatably connected to the inner wall of the outer shaft 3.

[0039] An outer column 5 is fixedly connected to the bottom end of the outer shaft 3, connecting the outer shaft 3 to the stirring assembly. This column transmits the rotation of the outer shaft 3 to the stirring assembly. Multiple stirring plates 6 are fixedly connected to the outside of the drive transmission assembly. These stirring plates 6 are used to stir and mix the wastewater and reagents in the reactor, increasing the material contact area. A vibrating plate 7 is slidably connected inside the stirring plate 6. During rotation, the vibrating plate 7 contacts the convex ball 11 and vibrates, repeatedly striking the inner wall of the reactor body 1 to prevent material adhesion. A limiting plate 8, which slides on the inner wall of the stirring plate 6, is fixedly connected to one side of the vibrating plate 7. The limiting plate 8 here is used to limit the sliding range of the vibrating plate 7 and prevent the vibrating plate 7 from falling out of the stirring plate 6. Two sliding columns 9 are fixedly connected to the side of the limiting plate 8 away from the vibrating plate 7. The sliding columns 9 here assist the limiting plate 8 in sliding stably on the inner wall of the stirring plate 6, ensuring that the vibrating plate 7 moves smoothly. The sliding columns 9 are slidably connected to the inner wall of the stirring plate 6. Two springs 10 are also fixedly connected to the side of the limiting plate 8 away from the vibrating plate 7. The springs 10 here generate elastic potential energy when the vibrating plate 7 is squeezed, providing the vibrating plate 7 with the reset power and the impact force to hit the inner wall of the vessel body 1.

[0040] The other end of the spring 10 is fixedly connected to one side of the inner wall of the stirring plate 6. Multiple convex balls 11 that contact the vibrating plate 7 are fixedly connected to the inner wall of the vessel body 1. When the vibrating plate 7 rotates, the convex balls 11 contact it, causing the vibrating plate 7 to be squeezed into the stirring plate 6, triggering the spring 10 to deform and store force. Multiple convex balls 11 are distributed in a multi-layered ring array along the inner wall of the vessel body 1. This distribution can increase the contact area between the convex balls 11 and the vibrating plate 7, ensuring the uniformity of vibration. The surface is coated with a polytetrafluoroethylene anti-stick coating, which reduces the adhesion of materials on the surface of the convex balls 11. The bottom end of the inner shaft 4 is fixedly connected to the inner column 12. The inner column 12 connects the inner shaft 4 to the one-way bearing 13, transmitting the rotation of the inner shaft 4 to the transmission component. The outer side of the inner column 12 is fixedly connected to the one-way bearing 13 that is rotatably connected to the inner wall of the outer column 5. The presence of the one-way bearing 13 here allows the large gear 14 to rotate only in one direction. When the large gear 14 is driven in the opposite direction, it does not affect the forward operation of the outer column 5 and the stirring assembly.

[0041] A large gear 14 is fixedly connected to the outside of the one-way bearing 13, transmitting the rotational power of the inner column 12 to the small gear 16. Multiple sliding rods 15 are rotatably connected to the inner wall of the outer column 5. These sliding rods 15 support the small gear 16 and the coil 17, and can slide up and down along the inner wall of the outer column 5, causing related components to engage and disengage. A small gear 16, meshing with the large gear 14, is fixedly connected to the outside of the sliding rod 15. This small gear 16 receives the rotational power from the large gear 14, causing the sliding rod 15 and the coil 17 to rotate. The inner... The wall is fixedly connected to the outside of the slide rod 15. When the coil 17 rotates, it winds or releases the pull rope 21, which drives the filter screen 24 to rotate to achieve a shearing action. At the same time, a reset spring is installed inside the filter screen 24. This reset spring can automatically reset when the coil 17 releases the pull rope 21. Multiple coils 17 are installed on the outside of the drive transmission component. A rotating rod 18 is fixedly connected to the top of the coil 17. The rotating rod 18 here can drive the coil 17, the pinion 16 and other components to rise and fall, so as to realize the engagement and disengagement of the pinion 16 and the large gear 14.

[0042] Two balls 19 are fixedly connected to the top of the rotating rod 18. These balls 19 slide in the threaded grooves on the inner wall of the sliding sleeve 20, providing the power for the rotating rod 18 to spiral up and down. The sliding sleeve 20 is slidably connected to the outside of the rotating rod 18, providing a sliding track for the balls 19. The spiral up and down of the rotating rod 18 is guided by the threaded grooves, and the balls 19 are slidably connected to the grooves on the inner wall of the sliding sleeve 20. A pull rope 21 is provided outside the coil 17, connecting the coil 17 and the filter screen 24, transmitting the rotational power of the coil 17 to the filter screen 24, causing the filter screen 24 to rotate. A sealing gasket 22 is slidably connected to the inner wall of the stirring plate 6. The sealing gasket 22 at the location can prevent wastewater, reagents and reaction products from seeping into the internal cavity of the stirring plate 6, protecting the internal components. The pull rope 21 is slidably connected to the inner wall of the sealing gasket 22. The inner wall of the stirring plate 6 is also fixedly connected to a rubber ring 23. The rubber ring 23 here has a rounded corner design, which guides the pull rope 21 and reduces wear during the movement of the pull rope 21, ensuring transmission stability. The pull rope 21 is slidably connected to the inner wall of the rubber ring 23. The other end of the pull rope 21 is fixedly connected to a filter screen 24 that is rotatably connected to the inner wall of the stirring plate 6. The filter screen 24 here cooperates with the filter screen 25 to form a shearing structure, which rotates under the drive of the pull rope 21 to cut up excessively large composite particles.

[0043] A filter screen 25 is rotatably connected to one side of filter screen 24 and fixedly connected to the inner wall of the stirring plate 6. Filter screen 25 and filter screen 24 work together to form a shearing action, further crushing the particles and preventing the particles from encapsulating air bubbles. The mesh wires of filter screen 24 and filter screen 25 are made of high-strength nickel-based alloy, which has excellent resistance to acid and alkali corrosion and mechanical strength, and can work stably for a long time in a strongly alkaline environment. A feed pipe 26 is fixedly connected to the top of the vessel body 1 for adding the wastewater to be treated and the reagent for purifying sodium silicate, realizing material input. A discharge pipe 27 is fixedly connected to the bottom of the vessel body 1 for discharging the treated material, realizing material output. An intercepting net 28 is fixedly connected to the inner wall of the discharge pipe 27. The intercepting net 28 can filter impurities in the treated material, which is convenient for the recycling of impurities.

[0044] Working principle: First, the wastewater to be treated and the reagent for purifying sodium silicate are simultaneously added through the feed pipe 26 at the top of the reactor body 1, ensuring that the two materials can achieve initial contact upon entering the reactor body 1. Then, the motor 2 in the top drive assembly is started. The motor 2 outputs power to drive the outer shaft 3 and the inner shaft 4 to rotate in the same direction in a special concentric but opposite-axis manner. The rotational speed of the inner shaft 4 is slightly lower than that of the outer shaft 3. This carefully designed difference in rotational speed forms the basis for differentiated linkage in the operation of the equipment, providing stable power conditions for the subsequent coordinated work of various components.

[0045] When the inner shaft 4 rotates, it drives the inner column 12 connected to the bottom to rotate synchronously. The rotation of the inner column 12 is transmitted to the external large gear 14 through the one-way bearing 13, causing the large gear 14 to rotate accordingly. Since the large gear 14 is in a meshing state with the small gear 16 on the slide rod 15, which is slidably connected to the inner wall of the outer column 5, the small gear 16 will rotate together with the rotation of the large gear 14, thereby driving the slide rod 15, the coil 17, and the top rotating rod 18 to rotate synchronously. The two balls 19 installed at the top of the rotating rod 18 slide continuously in the threaded groove of the inner wall of the sliding sleeve 20, generating a spiral upward force during the sliding process, causing the rotating rod 18 and a series of components connected to it, such as the coil 17 and the small gear 16, to move continuously upward.

[0046] Meanwhile, the outer shaft 3 rotates, driving the outer column 5 to rotate as well. The rotation of the outer column 5, in turn, drives the externally mounted stirring plate 6 and vibrating plate 7 to rotate synchronously. During rotation, the stirring plate 6 thoroughly mixes the wastewater and reagents in the reactor in all directions, greatly increasing the contact area and frequency of the two materials. During rotation, the vibrating plate 7 continuously contacts multiple protruding balls 11 fixedly installed on the inner wall of the reactor body 1. Each time it contacts, the vibrating plate 7 is squeezed into the interior of the stirring plate 6 by the protruding balls 11. At this time, the spring 10 connected to the inner side of the vibrating plate 7 is compressed. The compressed spring 10 generates a strong reaction force. The vibrating plate 7 uses this reaction force to repeatedly strike the inner wall of the reactor body 1, which can effectively prevent wastewater, reagents, and various products generated during the reaction from adhering to the inner wall of the reactor body 1, fundamentally avoiding the secondary pollution problem that may be caused by incomplete cleaning of residues.

[0047] During rotation, coil 17 simultaneously winds pull rope 21 around its surface. This winding of pull rope 21 causes the connected filter screen 24 to rotate. The rotating filter screen 24 forms a tight shearing fit with filter screen 25 installed on the inner wall of the stirring plate 6, precisely and thoroughly crushing excessively large composite particles generated in the reaction. Simultaneously, a reset spring is installed inside filter screen 24, which automatically winds pull rope 21 around its outside when coil 17 releases it, achieving reset. This reset process also shears large particles encasing the reactants. This shearing process not only prevents large particles from encasing air bubbles generated during the reaction and affecting its normal progress, but also further enhances the uniformity of material mixing, allowing wastewater and reagents to react more fully. The resulting products are more stable, significantly reducing the harm to water bodies, soil, and other surrounding environments during subsequent discharge, better meeting stringent environmental emission standards.

[0048] The sealing gasket 22 installed on the inner wall of the mixing plate 6 can effectively prevent wastewater, chemicals and other materials from seeping into the cavity inside the mixing plate 6, ensuring the normal operation of the internal components. The rubber ring 23 adopts a rounded corner design, which can significantly reduce the wear of the pull rope 21 during movement, thereby ensuring the stability and service life of the pull rope 21 transmission. When the rotating rod 18 drives the small gear 16 to rise to the moment it disengages from the large gear 14, the control system of the equipment will disconnect the power supply of the motor 2 in time. The coil 17 continues to rotate by its own inertia until its top touches the top of the inner wall of the outer cavity before it rotates in the opposite direction. At the same time, the ball bearing 19 outside the rotating rod 18 will slide down along the groove inside the sliding sleeve 20 until the small gear 16 contacts the teeth at the top of the large gear 14. Because the inner shaft 4 drives the inner column 12, the one-way bearing 13, and the large gear 14 at relatively slow speeds, the large gear 14 can smoothly re-engage with the small gear 16. After engagement, under the weight of components such as the coil 17 and the rotating rod 18, the small gear 16 drives the large gear 14 to rotate in the opposite direction and continue to descend until the small gear 16 touches the bottom. Since the one-way bearing 13 has a unidirectional transmission characteristic, the large gear 14, when driven to rotate in the opposite direction by the small gear 16, will not affect the forward operation of the outer column 5 or the stirring assembly. Finally, at the critical moment when the small gear 16 has fully reset and the outer column 5 is about to stop rotating but has not yet stopped, the motor 2 is restarted, thus forming a stable and efficient cyclic working mode.

[0049] After the reaction is complete, the operator opens the valve on the discharge pipe 27 at the bottom of the reactor body 1. The treated material is discharged through the discharge pipe 27. During the discharge process, the material passes through the interception net 28 installed on the inner wall of the discharge pipe 27. The interception net 28 effectively filters impurities in the material, realizing a closed-loop process for wastewater treatment. The intercepted impurities undergo further professional processing to recover their useful components, truly realizing the resource utilization of waste and achieving a green closed-loop process for wastewater treatment.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention 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 the present invention should be included within the protection scope of the present invention.
