Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, and in particular relates to a wastewater treatment device for chemical products. Background Technology

[0002] In the process of treating wastewater from chemical products, the reaction tank provides a stable mixing and reaction space for the wastewater and chemical treatment agents, ensuring that pollutants and agents come into full contact and react, ultimately achieving the precipitation or decomposition of heavy metal ions, organic pollutants, etc. Furthermore, the reaction tank must be used in conjunction with a mixing device to agitate the water and accelerate the mixing of wastewater and agents.

[0003] However, because the rectangular reaction tank is obstructed by the tank walls at its edges, water tends to flow parallel to the tank walls, forming a stagnant layer. The corner areas, being right-angled, also hinder effective water flow. These areas collectively constitute dead zones for wastewater mixing. Heavy metal ions and viscous pollutants contained in chemical wastewater cannot mix thoroughly with the reagents in these dead zones, leading to incomplete reactions and affecting the quality of the effluent.

[0004] The blade angles in existing mixing equipment are mostly fixed, which can only create an effective mixing flow field in the central area of ​​a rectangular reaction tank. When the blades move to the edge or corner area, the fixed angle cannot adapt to the water flow conditions in that area, making it difficult to generate radial turbulence strong enough to impact the stagnant water and drive the sewage in the dead corner area to participate in the overall mixing and circulation. This results in insufficient contact between the sewage in the dead corner area and the treatment agent, incomplete sedimentation of pollutants, fluctuations in effluent quality, and even failure to meet discharge standards. Summary of the Invention

[0005] The purpose of this invention is to provide a wastewater treatment device for chemical products, which solves the technical problem in the prior art where the blade tilt angle of the stirring device is fixed, resulting in insufficient stirring at the edges and corners of a rectangular reaction tank.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A wastewater treatment device for chemical products includes a reaction tank and a reaction-promoting mechanism installed in the reaction tank. The reaction-promoting mechanism includes a stirring assembly: the stirring assembly includes multiple connecting seats, each of which is rotatably equipped with multiple blades for stirring wastewater; and when the multiple blades move through the connecting seats to the edge area near the reaction tank, they rotate around the connecting seats to change their tilt angle, thereby enhancing the radial turbulence effect and eliminating the dead zones of wastewater stirring in the edge area and corner area.

[0007] According to some embodiments, the reaction-promoting mechanism further includes a support assembly, which includes: a support frame, fixedly installed at the bottom of the inner cavity of the reaction tank, on which two sprockets are rotatably mounted; a chain for driving the two sprockets to move synchronously; a first motor, fixedly installed on the support frame and fixedly connected to one of the sprockets; and a track, fixedly installed on the support frame, on which a movable seat fixedly connected to the chain is slidably mounted.

[0008] According to some embodiments, the reaction-promoting mechanism further includes a drive assembly, which includes: a mounting box on which a first hollow tube is rotatably mounted; a mounting bracket fixedly mounted on the mounting box, on which a second motor is fixedly mounted; two pulleys fixedly mounted on the power output shafts of the first hollow tube and the second motor, respectively; and a drive belt for driving the two pulleys.

[0009] According to some embodiments, the reaction-promoting mechanism includes an extension component, which includes a fixed box fixedly mounted on the movable seat, and a hydraulic telescopic cylinder fixedly mounted inside the fixed box; the drive component further includes a sliding box fixedly mounted on the mounting box and slidingly engaging with the telescopic end of the hydraulic telescopic cylinder.

[0010] According to some embodiments, the stirring assembly further includes: a second hollow tube, the top end of which is fixedly connected to the first hollow tube, and the outer surface of which is fixedly connected to the connecting seat; a plurality of mounting rings, all slidably mounted on the second hollow tube and connected to each other by a plurality of gear frames; and a first gear, fixedly mounted on the blade and meshing with the gear frame.

[0011] According to some embodiments, the stirring assembly further includes: a second rotating tube, fixedly mounted on the mounting ring; and a first rotating tube, rotatably mounted on the mounting box and connected to the second rotating tube via a first spring.

[0012] According to some embodiments, the reaction-promoting mechanism further includes a pressing assembly, which includes: a retaining tube fixedly mounted on the mounting box, on which a pressing post is slidably mounted; an extension post slidably mounted on the retaining tube and connected to the retaining tube by a third spring; the extension assembly further includes: a limiting frame fixedly connected to the fixed box and slidably connected to the mounting box.

[0013] According to some embodiments, the reaction-promoting mechanism further includes an aeration assembly, which includes: an aeration pipe fixedly installed on the paddle and extending into the interior of the second hollow tube; and a three-way pipe fixedly installed on the aeration pipe, on which a sliding rod is fixedly installed.

[0014] According to some embodiments, the aeration assembly further includes: a sealing frame, slidably mounted on the slide rod and connected to the tee pipe via a second spring; and a squeezing rod, fixedly mounted on the sealing frame.

[0015] According to some embodiments, the aeration assembly further includes: a positioning frame, fixedly installed on the second hollow tube; a plurality of inclined blocks, all fixedly installed on the positioning frame; the stirring assembly further includes: a spike, fixedly installed on the impeller.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The stirring assembly of the present invention moves within the reaction tank along with the support assembly. When the blades approach the edge or corner area, the pressing assembly squeezes and drives the toothed frame downward, causing the first gear to rotate and adjust the tilt angle of the blades around the connecting seat, increasing the radial thrust. The resulting turbulence directly impacts the stagnant water, breaking through the stirring dead angles that traditional fixed-angle blades cannot cover, allowing the wastewater in the dead angle area to participate in the overall circulation, further promoting the contact reaction between heavy metal ions, viscous pollutants and treatment agents in the wastewater from chemical products.

[0017] 2. This invention uses the sprocket and chain drive of the supporting component to drive the moving seat to move stably along the track, so that the stirring component covers the entire area of ​​the reaction tank. The hydraulic telescopic cylinder of the extension component can adjust the height of the mounting box and the stirring component to adapt to the confluence area formed by the depression at the bottom of the tank, and specifically stir the accumulated sewage. At the same time, the spikes on the blades can pierce and disperse pollutant flocs and sludge clumps, preventing clumps from encapsulating pollutants, and further improving the mixing uniformity of sewage and reagents.

[0018] 3. When external gas is introduced into the aeration component of this invention, the external gas enters the aeration pipe through the hollow tube and the three-way pipe, and is released into the sewage in the form of uniform bubbles. This provides oxygen for aerobic microorganisms to decompose organic pollutants. When the blades approach the edge, they drive the aeration pipe to rotate. The squeezing rod and the tilting block work together to increase the air inlet of the three-way pipe, thereby increasing the aeration volume in the edge area. The rising bubbles disturb the air and the blades stir the water, which enhances the mixing effect. At the same time, the spike cuts the bubbles to make them finer, improving the gas-liquid mass transfer efficiency and further promoting the stable achievement of effluent water quality standards.

[0022] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0025] This invention is described in detail with reference to the accompanying drawings. When detailing the embodiments of this invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not to scale. Furthermore, the accompanying drawings are merely examples and should not be construed as limiting the scope of protection of this invention.

[0026] Furthermore, it should be noted in the description of this invention that the terms "first," "second," or "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] Unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" in this invention should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; similarly, they can refer to mechanical connections, electrical connections, or direct connections, or indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] Example 1: As Figures 1 to 11As shown, a wastewater treatment device for chemical products includes a reaction tank 100 and a reaction-promoting mechanism 200 installed in the reaction tank 100. The reaction-promoting mechanism 200 includes a stirring assembly 240, which includes multiple connecting seats 246. Each connecting seat 246 is rotatably mounted with multiple blades 241 for stirring wastewater. When the multiple blades 241 move to the edge area near the reaction tank 100 through the connecting seats 246, they rotate around the connecting seats 246 to change their tilt angle, enhance the radial turbulence effect, and eliminate the dead zones of wastewater stirring in the edge area and corner area.

[0029] The wastewater from chemical products targeted by this invention mainly originates from the wastewater generated during the production of dyes, coatings, and electroplating auxiliaries. The core components of this type of wastewater include heavy metal ions such as copper, nickel, chromium, and zinc, as well as viscous pollutants such as resin residues, polymer intermediates, and emulsifier decomposition products. Among these, viscous pollutants tend to aggregate and clump together at the edges and corners of the reaction tank, encapsulating heavy metal ions to form a stable retention layer. This makes it difficult for traditional fixed-angle blades to disperse them, and the heavy metal ions cannot fully contact and react with the treatment agents.

[0030] This equipment uses a reaction tank 100 for chemical wastewater treatment. The reaction tank 100 can be rectangular or elliptical. Due to obstruction by the tank wall, the water flow in the edge area of ​​the reaction tank 100 tends to flow parallel to the tank wall, forming a stagnant layer. The corner area, being a right angle, makes it difficult for the water flow to form an effective circulation, easily creating a mixing blind zone. The aforementioned stagnant layer and blind zone are the wastewater mixing dead zones. The chemical wastewater in the dead zone cannot be fully mixed with the reagents, which can easily lead to insufficient precipitation of pollutants such as heavy metal ions, affecting the effluent quality. In the specific wastewater treatment process, after the chemical wastewater to be treated is introduced into the reaction tank 100, the reaction mechanism 200 moves within the tank. When it moves to the edge area or corner area of ​​the reaction tank 100, the blade 241 rotates around the connecting seat 246 to adjust the tilt angle, increasing the radial thrust of the blade 241 on the water. The resulting radial turbulence directly impacts the stagnant water at the edge and corner, driving the wastewater in the dead zone to participate in the overall mixing and circulation, allowing the wastewater to fully contact and mix with the treatment reagents.

[0031] like Figures 1 to 3As shown, the reaction-promoting mechanism 200 also includes a support assembly 210, which includes a track 211, a movable seat 212, a support frame 213, a chain 214, a sprocket 215, and a first motor 216. The support frame 213 is fixedly installed at the bottom of the inner cavity of the reaction tank 100, and two sprockets 215 are rotatably mounted on the support frame 213. The chain 214 is used to drive the two sprockets 215 to move synchronously. The first motor 216 is fixedly installed on the support frame 213 and is fixedly connected to one of the sprockets 215. The track 211 is fixedly installed on the support frame 213, and the movable seat 212, which is fixedly connected to the chain 214, is slidably installed on the track 211.

[0032] refer to Figure 3 It is known that when the first motor 216 is started, it will drive a sprocket 215 to rotate. Through the transmission of the chain 214, the other sprocket 215 will rotate synchronously. During this process, the chain 214 will continuously transmit power. Since the movable seat 212 is fixedly installed on the chain 214, the movable seat 212 will continuously transmit power along the chain 214. With the assistance of the track 211, the movable seat 212 can move stably along the specified trajectory. The movement of the movable seat 212 can move the paddle 241. The paddle 241 is used to assist in the mixing of sewage and chemical agents, so that the paddle 241 can continuously move within the reaction tank 100, assisting in the thorough mixing of sewage and chemical agents in each area of ​​the tank.

[0033] like Figure 2 and Figure 8 As shown, the reaction-promoting mechanism 200 also includes a drive assembly 220, which includes a second motor 221, a mounting box 222, a first hollow tube 223, a mounting bracket 224, pulleys 225, a drive belt 226, and a sliding box 227. The first hollow tube 223 is rotatably mounted on the mounting box 222. The mounting bracket 224 is fixedly mounted on the mounting box 222, and the second motor 221 is fixedly mounted on the mounting bracket 224. The two pulleys 225 are respectively fixedly mounted on the power output shafts of the first hollow tube 223 and the second motor 221. The drive belt 226 is used for the transmission connection between the two pulleys 225.

[0034] refer to Figure 8 It is known that when the first motor 216 starts, the second motor 221 will also start synchronously. The start of the second motor 221 will cause the first hollow tube 223 to rotate through the drive belt 226 and pulley 225. The first hollow tube 223 is connected to the stirring assembly 240, thereby causing the blades 241 on the stirring assembly 240 to rotate. In this way, the blades 241 can assist in mixing the sewage and chemical agents in the reaction tank 100.

[0035] like Figure 8 and Figure 9As shown, the reaction-promoting mechanism 200 includes an extension component 230, which includes a fixed box 231, a hydraulic telescopic cylinder 232, and a limiting frame 233. The fixed box 231 is fixedly installed on the movable seat 212, and the hydraulic telescopic cylinder 232 is fixedly installed inside the fixed box 231. The sliding box 227 is fixedly installed on the mounting box 222, and the sliding box 227 slides in cooperation with the telescopic end of the hydraulic telescopic cylinder 232.

[0036] refer to Figure 2 It can be seen that during the movement of the movable seat 212 along the trajectory, it will cause... Figure 9 The fixed box 231 moves together with the reaction tank 100. After one revolution, the fixed box 231 can be controlled to move the mounting box 222, causing the mounting box 222 to move continuously from the middle of the reaction tank 100 to the edge. This allows the paddle 241 to stir the reaction tank 100, helping to fully mix the wastewater and chemical agents. During long-term use, a depression will appear on the bottom surface of the inner cavity of the reaction tank 100. This depression will form a local confluence area, temporarily collecting the less fluid wastewater. If the paddle... When blade 241 is still at a fixed height, it will be unable to stir the sewage in the recessed area, resulting in insufficient treatment of the sewage in the reaction tank 100. However, since the mounting box 222 can move on the hydraulic telescopic cylinder 232, when it moves to the recessed area, the mounting box 222 and the stirring assembly 240 will sink as a whole, which makes it easier for blade 241 to stir the accumulated sewage in a targeted manner. This compensates for the problem of insufficient stirring caused by the dispersion of sewage on a flat surface, further improving the uniformity of mixing of the agent and sewage, so that sewage in all parts of the reaction tank 100 can achieve the expected treatment effect.

[0037] like Figures 6 to 11As shown, the stirring assembly 240 also includes a second hollow tube 242, a first rotating tube 243, a first gear 244, a spike 245, a second rotating tube 247, a mounting ring 248, a gear frame 249, and a first spring 2491; the top end of the second hollow tube 242 is fixedly connected to the first hollow tube 223, and the outer surface of the second hollow tube 242 is fixedly connected to the connecting seat 246; multiple mounting rings 248 are slidably mounted on the second hollow tube 242, and the multiple mounting rings 248 are connected by multiple gear frames 249; the first gear 244 is fixedly mounted on the impeller 241, and the first gear 244 meshes with the gear frame 249. The second rotating tube 247 is fixedly installed on the mounting ring 248; the first rotating tube 243 is rotatably installed on the mounting box 222, and the first rotating tube 243 is connected to the second rotating tube 247 through the first spring 2491; the reaction-promoting mechanism 200 also includes a pressing assembly 260, which includes a retaining tube 261, a third spring 262, an extension column 263, and a pressing column 264; the retaining tube 261 is fixedly installed on the mounting box 222, and the pressing column 264 is slidably installed on the retaining tube 261; the extension column 263 is slidably installed on the retaining tube 261, and the extension column 263 is connected to the retaining tube 261 through the third spring 262; the limiting frame 233 is fixedly connected to the fixing box 231, and the limiting frame 233 is slidably connected to the mounting box 222.

[0038] refer to Figure 8 It can be seen that as the mounting box 222 moves continuously away from the fixing box 231 and approaches the other end of the limiting bracket 233, Figure 11 The pressing column 264 on the upper part will squeeze against the limiting frame 233, thereby squeezing the liquid in the storage tube 261. With the help of hydraulic pressure, the extension column 263 will be moved out of the storage tube 261. The extension column 263 will be moved out, which will squeeze the second rotating tube 247, causing the second rotating tube 247 to move down along the second hollow tube 242. The downward movement of the second rotating tube 247 will drive the mounting ring 248 to move down. The downward movement of the mounting ring 248 will drive multiple gears 249 to move down. The downward movement of the gears 249 will drive the first gear 244 to rotate. The first gear 244 is fixedly connected to the blade 241, thereby driving the blade 241 to rotate. When the blade 241 is in the middle of the reaction tank 100, the tilt angle is small, and when it is in the inner edge of the reaction tank 100, the tilt angle is large.

[0039] When the blade 241 is at the center of the reaction tank 100, its small tilt angle is suitable for the uniform distribution of sewage in the central area. The gentle stirring action allows the sewage and chemical agents to be quickly and initially mixed, avoiding sewage splashing caused by excessive stirring. When the blade 241 moves closer to the edge of the reaction tank 100, the increased tilt angle expands the range of action of the stirring blade 241 and enhances the disturbance effect on the sewage in the edge area. At the same time, in response to the problem of sewage stagnation and accumulation at the edge of the reaction tank 100, the strong water flow impact force generated by the large tilt angle stirring breaks the static state of the stagnation area and promotes full contact and reaction between the sewage and the chemical agents in that area.

[0040] Furthermore, when the mounting box 222 and the stirring assembly 240 return to the center of the reaction tank 100, the second rotating tube 247 loses its compression due to the release of the pressing column 264 and will reset under the action of the first spring 2491, causing the mounting ring 248 and the gear frame 249 to move upward. This allows the blade 241 to reset its tilt angle and adapt to the mixing treatment of the reagent and sewage in the middle part of the reaction tank 100.

[0041] The working principle of this embodiment: The wastewater containing the chemical products to be treated is fed into the reaction tank 100, and the corresponding treatment agents are added. The reaction acceleration mechanism 200 is then activated to begin the mixing and reaction of the wastewater and the agents.

[0042] The first motor 216 of the support assembly 210 is started. The first motor 216 drives one sprocket 215 to rotate, and the other sprocket 215 rotates synchronously through the chain 214. The moving seat 212 is fixed to the chain 214 and slides along the track 211, driving the entire stirring assembly 240 to move along the track 211, so as to achieve full-area coverage stirring of the reaction tank 100.

[0043] The second motor 221 of the synchronous start drive assembly 220 drives the first hollow tube 223 to rotate via the pulley 225 and drive belt 226. The first hollow tube 223 is fixedly connected to the second hollow tube 242, driving the second hollow tube 242 and the connecting seat 246 to rotate synchronously. The blades 241 on the connecting seat 246 rotate accordingly, stirring the sewage and the agent. The spikes 245 on the blades 241 rotate synchronously, piercing and dispersing pollutant flocs and sludge clumps, improving the mixing uniformity.

[0044] Based on the depression at the bottom of the reaction tank 100, the hydraulic telescopic cylinder 232 of the extension component 230 is adjusted. The telescopic end of the hydraulic telescopic cylinder 232 drives the sliding box 227 to move, thereby adjusting the height of the installation box 222 and the stirring component 240 to adapt to the depression confluence area and specifically stir the accumulated sewage. When the stirring assembly 240 moves to a region close to the edge or corner of the reaction tank 100, the mounting box 222 slides along the limiting frame 233, and the pressing column 264 of the pressing assembly 260 presses against the limiting frame 233, causing the liquid in the storage tube 261 to push the extension column 263 out; the extension column 263 presses against the second rotating tube 247, causing the mounting ring 248 to move down along the second hollow tube 242. The mounting ring 248 is connected through the gear frame 249, causing the gear frame 249 to move down synchronously; the gear frame 249 meshes with the first gear 244, driving the blade 241 to rotate around the connecting seat 246, increasing the blade 241 tilt angle, strengthening radial turbulence, impacting the stagnant water in the edge and corner areas, and breaking the stirring dead zone.

[0045] When the stirring assembly 240 moves away from the edge area, the third spring 262 resets and pulls the extension column 263 back, the first spring 2491 pulls the second rotating tube 247 and the mounting ring 248 to move upward, the gear frame 249 drives the first gear 244 to rotate in the opposite direction, and the blade 241 tilts back to meet the stirring needs of the central area, ensuring that the sewage and the agent are fully mixed and reacted throughout the process.

[0046] Example 2: Figures 4 to 6 As shown, while all other parts are the same as in Example 1, the difference between this example and Example 1 is that: The reaction-promoting mechanism 200 also includes an aeration assembly 250, which includes an aeration pipe 251, a sealing frame 252, a sliding rod 253, a squeezing rod 254, a second spring 255, a three-way pipe 256, a positioning frame 257, and an inclined block 258. The aeration pipe 251 is fixedly installed on the blade 241 and extends into the interior of the second hollow pipe 242. The three-way pipe 256 is fixedly installed on the aeration pipe 251, and the sliding rod 253 is fixedly installed on the three-way pipe 256. The sealing frame 252 is slidably installed on the sliding rod 253 and is connected to the three-way pipe 256 through the second spring 255. The squeezing rod 254 is fixedly installed on the sealing frame 252. The positioning frame 257 is fixedly installed on the second hollow pipe 242. Multiple inclined blocks 258 are fixedly installed on the positioning frame 257. The spike 245 is fixedly installed on the blade 241.

[0047] The working principle of this embodiment: By installing an external air supply device on the first hollow tube 223, air is supplied to the inside of the first hollow tube 223. The gas then enters the second hollow tube 242 through the first hollow tube 223, and subsequently enters the three-way pipe 256 through the second hollow tube 242, finally entering the aeration pipe 251. With the help of the aeration pipe 251, the introduced gas can be released into the sewage in the reaction tank 100 in the form of uniform bubbles. This increases the contact area between the gas and the sewage, prolongs the bubble residence time, improves the gas-liquid mass transfer efficiency, and provides sufficient oxygen for aerobic microorganisms in the sewage to decompose organic pollutants. At the same time, the disturbance formed during the bubble rise can work synergistically with the stirring action of the blades 241 to enhance the uniformity of mixing between the sewage and chemical agents. When the aeration pipe 251 moves with the overall structure to a position close to the inner edge of the reaction tank 100, When the blade 241 rotates, it is fixedly connected to the aeration pipe 251 and will also rotate. This causes the squeezing rod 254 on the aeration pipe 251 to rotate as well. Due to the interaction between the tilting block 258 and the second spring 255, the squeezing rod 254 will continuously move away from the three-way pipe 256, thereby driving the sealing frame 252 away as well. This will continuously increase the air inlet of the three-way pipe 256, thereby increasing the aeration volume in the edge area. This will compensate for the problem of insufficient dissolved oxygen caused by the stirring blind zone and the accumulation of dirt in the depressions that are prone to occur at the edge. The larger flow of uniform bubbles will enhance the disturbance effect on the edge sewage. Combined with the increased stirring angle of the blade 241 when it approaches the edge, the contact reaction efficiency between the sewage and the agents and gases in the edge area will be further improved, ensuring that the sewage treatment effect in the center and edge areas of the reaction tank 100 is consistent.

[0048] Furthermore, the spike 245 can form a multi-dimensional piercing and stirring effect as the blade 241 rotates and moves. The spike 245 needles can pierce and disperse small pollutant flocs or activated sludge clumps formed after preliminary mixing in the wastewater, avoiding the clumps from encasing pollutants and preventing the reagents from fully contacting and reacting. During the rotation process, the spike 245 needles can lightly cut the rising aeration bubbles, assisting in further refining the bubbles and improving the gas-liquid mass transfer efficiency.
