Description

Technical Field

[0001] This invention belongs to the technical field of chemical wastewater treatment, and more specifically, relates to an integrated treatment device for chemical wastewater. Background Technology

[0002] Chemical production processes generate large amounts of acidic or alkaline wastewater. To meet emission standards or subsequent treatment requirements, it is usually necessary to add chemical agents to the wastewater in wastewater treatment ponds for neutralization. Existing chemical wastewater neutralization devices mostly use agitators or spraying devices installed in the treatment ponds to mix and react the chemical agents with the wastewater, thereby adjusting the pH of the wastewater.

[0003] The existing technologies for treating chemical wastewater still have the following drawbacks: In existing technologies, the neutralization treatment of chemical wastewater typically involves installing a single stirring device or a simple spraying structure within the treatment tank to mix and react the chemical agents with the wastewater. Because the wastewater is distributed vertically within the tank, especially in deeper tanks or areas with poor flow, the agents struggle to diffuse evenly across different heights, easily leading to localized neutralization or unreacted zones. This results in uneven neutralization reactions and unstable treatment outcomes.

[0004] In existing technologies, during the chemical neutralization process, some chemical agents are difficult to completely dissolve, and metal ions or impurities in the wastewater easily form precipitates or flocculent particles after the reaction. These particles tend to deposit and adhere to the bottom of the treatment tank or in structures such as pipes and filters. After long-term operation, this can cause blockage of the flow channels, reduced stirring efficiency, and increased equipment maintenance frequency, thereby affecting the continuous and stable operation of the wastewater treatment system.

[0005] In existing technologies, neutralization devices mostly rely on natural diffusion or localized stirring to achieve wastewater circulation, making it difficult to form an effective vertical convection flow field. When the wastewater concentration is high or the tank volume is large, the overall fluidity of the wastewater is poor, and it is difficult for the neutralized wastewater to exchange with the unneutralized wastewater in a timely manner, resulting in prolonged reaction time, low treatment efficiency, and increased operating costs.

[0006] Therefore, there is an urgent need to provide an integrated treatment device for chemical wastewater to solve the problems of insufficient wastewater mixing, easy particle deposition and clogging, and insufficient circulation capacity in the existing technology. Summary of the Invention

[0007] This invention provides an integrated treatment device for chemical wastewater, which solves the problems of insufficient mixing between the upper and lower zones of wastewater, easy deposition and clogging of particles, and insufficient circulation capacity in the prior art.

[0008] The purpose and effectiveness of the integrated treatment device for chemical wastewater of this invention are achieved by the following specific technical means: An integrated treatment device for chemical wastewater includes a treatment tank, the interior of which is fixedly provided with an inner cylinder, and further includes: A movable component, disposed inside the processing tank and capable of moving axially, divides the interior of the processing tank into at least two neutral zones of variable volume; A drive shaft passes through the movable part and is linked to it. The drive shaft cooperates with a guide drive assembly disposed inside the processing tank to generate axial lifting motion during rotation and drive the movable part to lift synchronously. A spray pipe assembly is disposed on the movable part and communicates with the neutralization area. One end of the spray pipe assembly can alternately communicate with wastewater in different height areas during the lifting and lowering of the movable part, and the other end of the spray pipe assembly is used to spray wastewater to another height area. A stirring component is disposed outside the jet pipe assembly. The jet pipe assembly can rotate during the lifting and lowering of the movable part to form a rotating diffusion flow when the wastewater is jetted.

[0009] With the above structure, the drive shaft rotates and moves axially up and down under the action of the guide drive assembly, thereby driving the moving parts to reciprocate inside the treatment tank and changing the volume of the neutralization zone. The spray pipe assembly moves up and down synchronously with the moving parts and alternately connects with wastewater in different height zones. At the same time, the spray pipe assembly rotates during its movement, and the stirring assembly, rotating with the spray pipe assembly, disturbs the wastewater. This enables the wastewater to form forced circulation and three-dimensional mixing between the upper and lower zones within the treatment tank, improving the uniformity of the neutralization reaction and reducing particle deposition.

[0010] Preferably, the guide drive assembly includes a cam fixedly disposed within the processing tank and an annular track formed on the cam, and the lower end of the drive shaft is provided with a movable cam that slides in cooperation with the annular track.

[0011] The above structure enables the linkage between the rotation and lifting of the drive shaft, improves the stability of the moving parts, and makes the volume change of the neutral zone more continuous.

[0012] Preferably, the movable component is disposed inside the cylinder and forms a sealing sliding fit with the cylinder. The cylinder is fixed inside the inner cylinder by a plurality of fixed tubes. The interior of the cylinder is divided into a first neutralization cavity and a second neutralization cavity by the movable component. Preferably, the neutralization region is formed inside the cylinder.

[0013] With the above structure, the moving parts slide in a sealed manner inside the cylinder, causing the volume of the first neutralization chamber and the second neutralization chamber to change alternately, thereby driving the wastewater to flow between the two neutralization chambers, forming a zoned neutralization reaction environment, and improving the contact efficiency between wastewater and chemical agents.

[0014] Preferably, the injection pipe assembly includes a plurality of circular pipes, which are circumferentially distributed on the movable member.

[0015] With the above structure, when the moving parts are raised and lowered, multiple circular pipes move synchronously with them, allowing wastewater from different height areas to enter the circular pipes and be transported to another height area, enhancing the vertical circulation of wastewater and increasing the overall flow field disturbance.

[0016] Preferably, a circular plate is rotatably provided at the upper and lower ends of the cylinder, and the outer wall of the cylinder is threadedly guided to a sleeve fixed on the circular plate so that the cylinder rotates when it moves axially. Several one-way valves are provided on the circular plate.

[0017] With the above structure, the circular tube rotates during axial movement by forming a threaded guide with the sleeve. At the same time, the wastewater flows in a directional manner through the one-way valve, so that the wastewater spray has a rotational diffusion effect, which improves the neutralization and mixing effect and reduces backflow.

[0018] Preferably, a plurality of pairs of stirring elements are provided on the outer side of the circular tube. The stirring elements are used to create radial disturbance to the wastewater when the circular tube rotates. Two rubber elements are symmetrically arranged between each pair of stirring elements. A plurality of support elements are spaced apart between the two rubber elements. A plurality of channels are provided between the two rubber elements through the plurality of support elements. All of the plurality of channels are connected to the circular tube.

[0019] With the above structure, when the circular tube rotates, it drives the agitator to disturb the wastewater. The wastewater enters the area around the agitator through the channel, forming a radial diffusion flow, which enhances the local mixing of the wastewater, avoids liquid stratification, and improves the neutralization reaction rate.

[0020] Preferably, the upper part of the first neutralization cavity is provided with a plurality of first particle processing components, the first particle processing components are located on the lower side of the movable component, and the first particle processing components rotate and move with the movable component. The upper part of the second neutralization cavity is provided with a plurality of second particle processing components, the second particle processing components are located at the upper end of the cylinder, and the second particle processing components are fixedly connected to the cylinder.

[0021] With the above structure, the first particle processing component rotates and rises with the moving part to process the particles in the first neutralization chamber; the second particle processing component is fixed on the cylinder to process the particles in the second neutralization chamber; thus reducing the risk of particle deposition during the neutralization process and reducing equipment blockage.

[0022] Preferably, the first particle processing assembly includes a housing, with an annular grinding element disposed below the housing, and an elastic element connected between the annular grinding element and the lower side of the housing. A push rod is vertically slidably disposed in the middle of the housing, with a grinding element disposed at the lower end of the push rod. A pair of top rods are fixedly disposed on the upper side of the annular grinding element, and the pair of top rods are vertically slidably in contact with the housing. A pair of movable blocks are symmetrically horizontally slidably disposed inside the housing. The ends of the pair of movable blocks that are close to each other are slidably in contact with the upper inclined surfaces on both sides of the push rod, and the ends of the pair of movable blocks that are far apart from each other are respectively slidably in contact with the upper inclined surfaces of the two top rods. The structure of the first particle processing assembly is the same as the structure of the second particle processing assembly.

[0023] With the above structure, when the moving part moves, it pushes the push rod up and down, causing the grinding part and the annular grinding part to move closer or further apart, thereby squeezing and grinding the particles; improving the particle crushing effect and enhancing the flowability of wastewater.

[0024] Preferably, a slider is fixedly provided on the upper side of the housing, the slider in the first particle processing assembly slides radially at the lower part of the movable member, and the slider in the second particle processing assembly slides radially on the upper side of the second neutralization cavity.

[0025] With the above structure, the slider slides in the radial direction, which keeps the particle processing component stable and guided during the movement of the moving parts, improves the working reliability of the particle processing component and reduces jamming.

[0026] Preferably, the upper end of the processing tank is provided with a sealing cover, and a driver is installed on the upper side of the sealing cover. The upper outer wall of the drive shaft is axially engaged with the spline of the driver.

[0027] Compared with the prior art, the present invention has the following beneficial effects: This invention discloses an integrated treatment device for chemical wastewater. By incorporating a movable component, a drive shaft, and a guide drive assembly, the drive shaft rotates while simultaneously moving axially up and down, causing the movable component to reciprocate within the treatment tank and alter the volume of the neutralization zone. A spray pipe assembly rises and falls synchronously with the movable component, alternately connecting with wastewater at different heights. During this rising and falling process, the assembly rotates, driving a stirring assembly to rotate as well. This creates forced circulation and three-dimensional mixing of the wastewater between the upper and lower zones within the treatment tank, improving the uniformity of neutralization between the chemical wastewater and the chemical agents. Furthermore, by installing the spray pipe assembly on the movable component, wastewater from one height zone can be transported to another height zone and discharged via spraying as the movable component moves axially. This promotes the flow exchange of wastewater between different zones within the treatment tank, increases the overall flow field disturbance, and shortens the neutralization reaction time. Finally, the spray pipe assembly, during its axial movement, forms a guiding engagement with the sleeve, causing the spray pipe assembly to rotate and simultaneously drive the stirring assembly to rotate. This creates a swirling diffusion flow of wastewater during spraying, thereby increasing the contact area between the wastewater and the chemical agents and improving the neutralization reaction efficiency.

[0028] This invention discloses an integrated treatment device for chemical wastewater. By incorporating a movable component within a cylindrical chamber to form a first neutralization chamber and a second neutralization chamber, wastewater flows alternately between the two chambers, creating a partitioned neutralization reaction environment and improving the sufficiency of the reaction between the wastewater and chemical agents. Furthermore, by respectively arranging a first particle processing component and a second particle processing component within the first and second neutralization chambers, particles are ground and crushed between the particle processing components during the rotation and axial movement of the movable component, thereby reducing particle deposition and improving the operational stability of the device.

[0029] This invention discloses an integrated treatment device for chemical wastewater. The grinding elements and annular grinding elements in the particle treatment assembly approach each other during the movement of the moving parts, creating a grinding effect that crushes and breaks up deposited particles, improving wastewater flowability and reducing the risk of channel blockage. Furthermore, the first and second particle treatment components, guided radially, contact the filter screen, cleaning particles from the filter screen surface during operation, thus maintaining the filter's filtration efficiency and reducing maintenance frequency.

[0037] As attached Figure 1 To be continued Figure 14 As shown: This invention provides an embodiment of an integrated treatment device for chemical wastewater. See attached document Figure 1 To be continued Figure 14 The system includes a processing tank 10, with an inner cylinder 15 fixedly installed inside the processing tank 10, and also includes: The movable part 31 is disposed inside the processing tank 10 and is capable of moving axially to divide the interior of the processing tank 10 into two neutral regions with variable volumes. A drive shaft 20 is installed through and linked to the movable part 31. The drive shaft 20 cooperates with the guide drive assembly installed in the processing tank 10 to generate axial lifting motion when rotating and drive the movable part 31 to lift synchronously. The spray pipe assembly is mounted on the movable part 31 and communicates with the neutralization area. One end of the spray pipe assembly can alternately communicate with wastewater in different height areas during the lifting and lowering of the movable part 31, and the other end of the spray pipe assembly is used to spray wastewater to another height area. A stirring component is located outside the jet pipe assembly. The jet pipe assembly can rotate during the lifting and lowering of the movable part 31 to form a rotating diffusion flow when the wastewater is jetted.

[0038] In practice, the drive shaft 20 rotates and moves axially up and down under the action of the guide drive assembly, thereby driving the movable part 31 to move back and forth inside the treatment tank 10 and change the volume of the neutralization area; the spray pipe assembly moves up and down synchronously with the movable part 31 and alternately connects with the wastewater in different height areas. At the same time, the spray pipe assembly rotates during the movement, and the stirring assembly rotates with the spray pipe assembly to disturb the wastewater; thus, the wastewater forms a forced circulation and three-dimensional mixing between the upper and lower areas in the treatment tank 10, improving the uniformity of the neutralization reaction and reducing particle deposition.

[0039] Preferred options are shown in the appendix. Figure 6 To be continued Figure 7 The guide drive assembly includes a cam 27 fixedly disposed in the processing tank 10 and an annular track 28 formed on the cam 27. The lower end of the drive shaft 20 is provided with a movable cam 29 that slides in cooperation with the annular track 28. A protrusion 30 is provided on one side of the lower part of the movable cam 29, and the lower end of the protrusion 30 slides in the annular track 28.

[0040] Preferred options are shown in the appendix. Figure 8 The movable part 31 is disposed inside the cylinder 17 and forms a sealed sliding fit with the cylinder 17.

Several channels 42 are separated between the two rubber parts 40 by the several support parts 41. Several channels 42 are all connected to the circular pipe 35. Several one-way valves 56 are provided on the circular plate 19.

[0042] In practical implementation, channel 42 reduces the blockage of the circular pipe 35 by impurities in the chemical wastewater, allowing the solution inside the circular pipe 35 to be sprayed out through channel 42. Furthermore, the elasticity of the rubber components 40 allows them to deform and return to their original shape during the stirring of the chemical wastewater. The deformation of the two rubber components 40 reduces the space of channel 42, further reducing impurities from clogging it; and after the two rubber components 40 return to their original shape, the space of channel 42 increases, which, combined with the solution sprayed from the circular pipe 35, allows impurities to be discharged.

[0049] Preferred options are shown in the appendix. Figure 6 Appendix Figure 11 The lower outer wall of the drive shaft 20 is provided with a conical block 22, and the outer wall of the conical block 22 is provided with a spiral component 23.

[0050] Preferred options are shown in the appendix. Figure 1 To be continued Figure 3 Appendix Figure 11The lower end of the inner cylinder 15 is provided with a bottom plate 16. A drain pipe 24 is provided on one side of the lower part of the inner cylinder 15. A collection box 25 is provided on the other side of the lower end of the inner cylinder 15. Several filter holes 13 are provided on the bottom plate 16. The filter holes 13 are all located inside the collection box 25. The collection box 25 is connected to the outside of the treatment tank 10 by a discharge pipe 26. An electrical distribution box 14 is provided outside the treatment tank 10. A control valve 32 is provided in the connection between the fixed pipe 18 and the inside of the cylinder 17. The upper part of the inner cylinder 15 is connected to the external chemical wastewater pool by an inlet pipe 21. The fixed pipe 18 is connected to the external chemical reagent cylinder.

[0051] Specific usage of this invention: Chemical wastewater in the chemical wastewater tank is transported to the interior of the inner cylinder 15 through the inlet pipe 21. The control system starts the driver 12, which drives the drive shaft 20 to rotate.

[0052] When the drive shaft 20 rotates, it drives the movable cam 29 and the protrusion 30 to rotate synchronously. The protrusion 30 moves under the guidance of the annular track 28, thereby causing the drive shaft 20 to move axially up and down during rotation. Since the upper outer wall of the drive shaft 20 forms a spline axial fit with the driver 12, the drive shaft 20 can still maintain continuous rotation during lifting and lowering.

[0053] The rotation and lifting linkage of the drive shaft 20 drives the conical block 22 and the spiral component 23 to rotate synchronously and move axially, thereby creating a stirring disturbance on the chemical wastewater in the lower part of the inner cylinder 15 and improving the flowability of the wastewater.

[0054] When the drive shaft 20 moves upward, it drives the movable part 31 to slide upward inside the cylinder 17, increasing the volume of the first neutralization chamber 33 and creating a negative pressure. This draws the chemical wastewater below the cylinder 17 into the first neutralization chamber 33 through the lower one-way valve 56. Simultaneously, external chemical agents are quantitatively introduced into the first neutralization chamber 33 through the control valve 32, allowing the wastewater and chemical agents to undergo a preliminary neutralization reaction within the first neutralization chamber 33.

[0055] During this process, the rotation of the drive shaft 20 drives the rotation of the movable part 31, and the rotation of the movable part 31 causes the spray pipe assembly and the first particle treatment assembly 43 to rotate synchronously, thereby creating a stirring effect on the wastewater in the first neutralization chamber 33.

[0056] When the movable part 31 moves upward, it drives the circular tube 35 to move upward through the limiting ring 36, so that the wastewater in the second neutralization chamber 34, after preliminary neutralization, enters the lower circular tube 35 through the filter screen 37, and is sprayed to the lower area of ​​the inner cylinder 15 through the channel 42, thereby realizing the downward transportation of wastewater from the upper part and promoting the full mixing of wastewater in the upper and lower areas of the inner cylinder 15.

[0057] Since the outer wall of the round tube 35 and the inner wall of the sleeve 38 form a threaded guide fit, the round tube 35 rotates during axial movement, thereby driving the agitator 39 and the rubber part 40 to rotate, so that the sprayed wastewater is discharged in a diffused state, improving the mixing effect.

[0058] During the chemical neutralization process, particulate or flocculent sediments may be generated in the wastewater. These particles easily adhere to the inner wall of the second neutralization chamber 34 or the surface of the filter screen 37. The up-and-down movement of the movable part 31 can create a scouring effect on the adhered particles. At the same time, the relative movement between the second particle treatment component 44 and the movable part 31 allows the particles to enter and be ground and crushed.

[0059] During the particle grinding process, the grinding element 51 first crushes the particles by squeezing. Then, the push rod 52 moves upward under force, driving the movable block 53 to move, which in turn causes the top rod 54 to push the annular grinding element 50 downward, thereby forming a complete grinding surface for further grinding of the particles. The elastic element 49 provides elasticity during the resetting process of the annular grinding element 50, allowing the grinding structure to return to its initial state.

[0060] As the movable part 31 continues to move upward, the second guide ring 47 pushes the second particle processing assembly 44 to move radially, so that it comes into contact with the filter screen 37, thereby cleaning the particles on the surface of the filter screen 37.

[0061] When the drive shaft 20 moves downward, the movable part 31 moves downward simultaneously, so that the wastewater in the first neutralization chamber 33 enters the upper circular pipe 35 through the filter screen 37 and is sprayed to the upper area of ​​the inner cylinder 15, realizing the upward transportation of wastewater from the lower part.

[0062] Meanwhile, the circular tube 35 continues to rotate during axial movement, causing the sprayed wastewater to form a spiral diffusion flow, further improving the mixing effect of wastewater and chemical agents.

[0063] In addition, the first particle processing component 43 cooperates with the annular plate 45 during the rotation and descent of the movable part 31 to grind the deposited particles in the first neutralization cavity 33, and moves radially under the guidance of the first guide ring 46 to clean the filter screen 37.

[0064] Through the synergistic effect of the above structures, the moving part 31 drives the jet pipe assembly to circulate and transport wastewater in the upper and lower areas of the inner cylinder 15 during rotation and axial reciprocating motion. At the same time, the neutralization reaction is enhanced by self-rotating jetting and multi-stage stirring, thereby significantly improving the efficiency of chemical wastewater treatment.

[0065] This invention discloses an integrated treatment device for chemical wastewater. By incorporating a movable component 31, a drive shaft 20, and a guide drive assembly, the drive shaft 20 rotates while simultaneously moving axially up and down, thereby driving the movable component 31 to reciprocate within the treatment tank 10 and altering the volume of the neutralization zone. A spray pipe assembly rises and falls synchronously with the movable component 31, alternately connecting with wastewater at different heights. During this rising and falling process, the assembly rotates, driving the stirring assembly to rotate as well. This creates forced circulation and three-dimensional mixing of the wastewater between the upper and lower zones within the treatment tank 10, improving the uniformity of neutralization between the chemical wastewater and the chemical agents. Furthermore, by installing the spray pipe assembly on the movable component 31, wastewater from one height zone can be transported to another height zone and discharged via spraying when the movable component 31 moves axially. This promotes the flow and exchange of wastewater between different zones within the treatment tank 10, increases the overall flow field disturbance, and shortens the neutralization reaction time. Finally, the spray pipe assembly forms a guiding fit with the sleeve 38 during axial movement, causing the spray pipe assembly to rotate. At the same time, it drives the stirring assembly to rotate, so that the wastewater forms a rotating diffusion flow during the spraying process, thereby increasing the contact area between the wastewater and the chemical agent and improving the neutralization reaction efficiency.

[0066] This invention discloses an integrated treatment device for chemical wastewater. By incorporating a movable component 31 within a cylindrical chamber 17 to form a first neutralization chamber 33 and a second neutralization chamber 34, wastewater flows alternately between the two chambers, creating a partitioned neutralization reaction environment and improving the sufficiency of the reaction between the wastewater and chemical agents. Furthermore, by respectively incorporating a first particle processing component 43 and a second particle processing component 44 within the first neutralization chamber 33 and the second neutralization chamber 34, particles are ground and crushed between the particle processing components during the rotation and axial movement of the movable component 31, thereby reducing particle deposition and improving the operational stability of the device.
