Description

Technical Field

[0001] This invention relates to the field of pH control technology, and in particular to a pH control device for grey water. Background Technology

[0002] In the field of greywater treatment, pH control is a key process for measuring the acidity or alkalinity of water and adding regulators to bring greywater to a neutral or specific pH range. It is commonly used in wastewater treatment systems of industries such as coal-fired power plants and chemical plants to effectively reduce the corrosiveness and environmental pollution risks of greywater through neutralization reactions.

[0003] Existing technologies, such as the invention with publication number CN117418118A, disclose a method for removing impurities from indium sponge using pH control during the leaching process. First, an H2SO4 solution is prepared using production water. Then, indium sponge is added to the prepared H2SO4 solution and stirred and heated to react. After the reaction, NaOH solution is added to the resulting solution to adjust its pH to 4.5. The solution is then stirred and allowed to settle for 1.5 hours under natural cooling conditions. The settled solution is then filtered, and the filtrate is sent for testing. The precipitate is the impurity-removed indium sponge. The filtrate is recycled by adding acid to adjust its pH.

[0004] This invention utilizes a method of removing impurities from indium sponge by adjusting the pH during the leaching process, which solves the problem of high impurity content and low grade of existing indium sponge in the extraction production process, thereby improving the applicability of the indium recovery system to different types of indium sponge.

[0005] During the pH adjustment of greywater, it is necessary to filter the greywater entering the equalization tank. However, since most filter devices are bolted or integrally welded, it is inconvenient to quickly disassemble and clean them. This leads to the long-term accumulation of debris that clogs the filter mesh, affecting the influent flow rate and reducing the accuracy of pH control. Summary of the Invention

[0006] The purpose of this invention is to solve the shortcomings of existing technologies, such as the inconvenience of disassembly and cleaning due to the use of bolts for fixing, the easy clogging of the mesh by debris, the impact on the inlet water flow, and the low pH control accuracy.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a greywater pH control device, comprising an adjustment tank and a filtration device, wherein an inlet pipe is fixedly connected to one side of the adjustment tank, and an outlet is fixedly connected to the lower end of one side of the adjustment tank. A filtration device is disposed on the inner wall of the adjustment tank corresponding to the position of the inlet pipe. The filtration device includes a filter tube, both ends of which are slidably connected to the inner wall of the adjustment tank. Mounting plates are fixedly connected to both ends of the filter tube. Slider blocks are fixedly connected to both sides of the mounting plates. A sliding groove is formed on the inner wall of the adjustment tank corresponding to the position of the slider. The surface of the slider is slidably connected to the inner wall of the sliding groove. A first fixing groove is formed at the upper end of the mounting plate. A guide groove is formed on one side of the mounting plate corresponding to the position of the first fixing groove. Limiting plates are fixedly connected to the upper end of the adjustment tank corresponding to the positions of the two mounting plates. A limiting rod slides through the surface of the limiting plate, and one end of the limiting rod's arc surface is slidably connected to the inner wall of the first fixing groove.

[0008] The aforementioned components achieve the following effects: the filter device can be quickly installed and disassembled through the slidingly connected filter tube and the pluggable limiting rod, facilitating regular cleaning or replacement of the filter components and avoiding the problem of pH control accuracy being affected by debris blockage.

[0009] Preferably, both ends of the filter tube are fixedly connected with sealing rings, and the sealing rings are made of rubber.

[0010] The effect achieved by the above components is as follows: by setting rubber sealing rings at both ends of the filter tube, elastic compression is formed when the filter tube slides and fits against the inner wall of the regulating tank, achieving a good sealing effect and preventing unfiltered gray water from leaking out of the gaps.

[0011] Preferably, a spring is fitted onto the arc surface of one end of the limiting rod, and the two ends of the spring are fixedly connected to the surface of the limiting rod and the inner wall of the first fixing groove, respectively.

[0012] The effect achieved by the above components is as follows: by setting a spring on the limit rod, when the external force is removed, the spring force can push the limit rod to automatically lock into the first fixing groove, realizing the automatic reset function of the limit rod and simplifying the locking operation.

[0013] Preferably, both ends of the limiting plate are fixedly connected to fixing plates, and a fixing bolt is threaded through one side of the fixing plate. One end of the fixing bolt has an arc surface that slides into the inner wall of the mounting plate.

[0014] The effect achieved by the above components is as follows: by tightening the fixing bolts to insert them into the mounting plate, the mounting plate is locked a second time based on the initial positioning of the limiting rod, so as to achieve complete fixation and prevent the filter device from loosening due to equipment vibration.

[0015] Preferably, a stirring device is provided at the lower end of the regulating tank. The stirring device includes a motor and two stirring columns. The motor is fixedly connected to the regulating tank. Both ends of the two stirring columns are slidably connected to the inner wall of the regulating tank. One end of one of the stirring columns is fixedly connected to the output end of the motor. One end of each of the two stirring columns is fixedly connected to a synchronous pulley. The arc surfaces of the two synchronous pulleys are fitted with the same synchronous belt.

[0016] The effect achieved by the above components is as follows: by driving a stirring column to rotate by a motor, and by using the transmission of a synchronous pulley and a synchronous belt to make two stirring columns rotate synchronously, the ash water in the equalization tank is thoroughly stirred, the mixing uniformity of pH adjuster and ash water is improved, thereby accelerating the stabilization of pH value.

[0017] Preferably, a protective cover is fixedly connected to one side of the regulating tank corresponding to the position of the motor, and the inner wall of the protective cover is adapted to the size of the motor.

[0018] The effect achieved by the above-mentioned components is that by setting a protective cover that matches the size of the motor, the motor is completely covered, which plays a role in waterproofing and dustproofing, and avoids damage to the motor caused by gray water.

[0019] Preferably, ventilation pipes are provided on both ends of the protective cover, and the ventilation pipes are arranged radially.

[0020] The effect achieved by the above components is as follows: by opening radial ventilation pipes at both ends of the protective cover, an effective air convection channel is formed while ensuring that water splashes in, thereby achieving heat dissipation of the motor and preventing the motor from overheating during long-term operation.

[0021] Preferably, a ventilation device is installed at the upper end of the regulating pool. The ventilation device includes four hydraulic rods and a suction fan. The four hydraulic rods are fixedly connected to the four corners of the upper end of the regulating pool. The upper ends of the four hydraulic rods are fixedly connected to the same gas collection hood. The upper end of the gas collection hood is fixedly connected to a gas collection pipe. A docking assembly is provided at the upper end of the gas collection pipe. A suction fan is provided at one end of the regulating pool. The output end of the suction fan is fixedly connected to a collection pipe. The input end of the suction fan is fixedly connected to a gas delivery pipe. One end of the gas delivery pipe is fixedly connected to the gas collection pipe via the docking assembly. The docking assembly includes a fixing ring and a docking ring. The inner wall of the fixing ring is fixedly connected to the arc surface of the gas collection pipe. Two rotating frames are fixedly connected to the upper two sides of the docking ring. A rotating rod is rotatably mounted on the inner wall of the rotating frame. A fixing block is fixedly connected to the arc surface of the rotating rod. The cross-section of the fixing block is U-shaped, and the lower end of the fixing block is an inclined surface.

[0022] The above components achieve the following effects: the height of the gas collection hood is adjusted by the hydraulic rod, and the harmful gas generated in the regulating pool is sucked out by the suction fan; at the same time, the U-shaped fixing block with the sloping bottom can automatically lock the docking ring and the fixing ring under the action of gravity or external force, realizing the rapid and reliable docking of the gas collection pipe and the gas delivery pipe.

[0023] Preferably, one side of the upper end of the fixing block is an inclined surface, the arc surface of the gas collecting pipe is rotatably connected to a rotating ring, and both sides of the lower end of the rotating ring are fixedly connected to a fixing pin and a pressing rod. The arc surface of the fixing pin is slidably connected to the inner wall of the fixing block, and the lower end of the pressing rod abuts against the surface of the fixing block.

[0024] The effect achieved by the above components is as follows: by rotating the rotating ring, the squeezing rod is driven to squeeze the upper inclined surface of the fixed block, or the fixed pin is driven to exit from the fixed block, thus realizing the function of unlocking when the rotating ring rotates clockwise and locking the fixed block when it rotates counterclockwise, which facilitates the on / off control of the pipeline.

[0025] Preferably, a coil spring is sleeved on the surface of the rotating rod, and the two ends of the coil spring are fixedly connected to one end of the rotating rod and one side of the fixing block, respectively.

[0026] The effect achieved by the above components is as follows: by setting a coil spring between the rotating rod and the fixed block, the torque of the coil spring makes the fixed block tend to remain in a clamped state when no external force is applied, thereby enhancing the stability of the docking and the self-locking performance.

[0027] Compared with the prior art, the advantages and positive effects of the present invention are as follows: In this invention, by setting up a filtration device, when cleaning is required, simply pull out the limiting rod upwards to slide the filter tube out of the regulating tank along the slide groove. After cleaning, push in and release the limiting rod. The spring pushes the limiting rod to automatically engage with the first fixing groove. Then tighten the fixing bolt to complete the secondary locking. At the same time, the sealing ring forms elastic compression during sliding to prevent leakage, thereby realizing the quick disassembly and assembly and reliable sealing of the filtration device. This effectively solves the problem of the influent flow rate and pH control accuracy being affected by debris clogging the mesh.

[0028] In this invention, a stirring device is installed. A motor drives one stirring column to rotate, and through the transmission of a synchronous pulley and a synchronous belt, two stirring columns rotate synchronously, which fully stirs the ash water in the regulating tank, significantly improving the mixing uniformity of the pH adjuster and the ash water, thereby accelerating the stabilization of the pH value. At the same time, the protective cover completely covers the motor, which serves to prevent water and dust. Combined with the radial ventilation pipes at both ends, air convection is formed to dissipate heat, preventing the motor from being damaged by moisture or overheating, and ensuring the long-term stable operation of the stirring process.

[0029] In this invention, by setting up a ventilation device, the height of the gas collection hood can be adjusted by the hydraulic rod to adapt to different liquid levels. The suction fan sends the harmful gases generated in the regulating tank to the collection pipe for centralized treatment through the gas collection pipe and the gas delivery pipe. During docking, the U-shaped fixing block with the lower end being inclined automatically clamps the fixing ring and the docking ring. The coil spring keeps the fixing block in a clamped state. When separation is required, rotating the rotating ring drives the squeezing rod to unlock, realizing the rapid and reliable docking and on / off control of the pipeline, effectively avoiding the health hazards of harmful gas leakage to operators.

[0032] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] Numerous 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 than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0034] like Figure 1 - Figure 2 As shown, the present invention provides a pH control device for grey water, including an adjustment tank 1 and a filter device 3. An inlet pipe 2 is fixedly connected to one side of the adjustment tank 1, and an outlet 4 is fixedly connected to the lower end of one side of the adjustment tank 1. The filter device 3 is installed on the inner wall of the adjustment tank 1 at the position corresponding to the inlet pipe 2. A stirring device 5 is installed at the lower end of the adjustment tank 1, and an air exchange device 6 is installed at the upper end of the adjustment tank 1.

[0035] The following section will describe in detail the specific setup and function of its filter device 3, stirring device 5, and ventilation device 6.

[0036] like Figure 3 - Figure 5As shown, the filtration device 3 includes a filter tube 301, both ends of which are slidably connected to the inner wall of the regulating tank 1. Mounting plates 302 are fixedly connected to both ends of the filter tube 301. Slider blocks 303 are fixedly connected to both sides of the mounting plates 302. A groove 312 is formed on the inner wall of the regulating tank 1 corresponding to the position of the slider 303. The surface of the slider 303 is slidably connected to the inner wall of the groove 312. A first fixing groove 305 is formed at the upper end of the mounting plate 302. One side of the mounting plate 302 corresponds to the first fixing groove 305. A guide groove 304 is provided at the position. Limiting plates 306 are fixedly connected to the upper end of the regulating tank 1 at positions corresponding to the two mounting plates 302. Limiting rods 307 slide through the surface of the limiting plates 306. One end of the limiting rod 307 has an arc surface that slides into the inner wall of the first fixing groove 305. Through the slidably connected filter tube 301 and the pluggable limiting rods 307, the filter device 3 can be quickly installed and disassembled, facilitating regular cleaning or replacement of filter components and avoiding the problem of pH control accuracy being affected by debris blockage. Sealing rings 309 are fixedly connected to both ends of the filter tube 301. The sealing rings 309 are made of rubber. By setting rubber sealing rings 309 at both ends of the filter tube 301, elastic compression is formed when the filter tube 301 slides against the inner wall of the regulating tank 1, achieving a good sealing effect and preventing unfiltered greywater from leaking through gaps. A spring 308 is fitted onto the arc-shaped surface of one end of the limiting rod 307. The two ends of the spring 308 are fixedly connected to the surface of the limiting rod 307 and the inner wall of the first fixing groove 305, respectively. By installing the spring 308 on the limiting rod 307, when the external force is removed, the elastic force of the spring 308 can push the limiting rod 307 to automatically engage with the first fixing groove 305, achieving the automatic reset function of the limiting rod 307 and simplifying the locking operation. Fixing plates 310 are fixedly connected to both ends of the limiting plate 306. A fixing bolt 311 is threaded through one side of the fixing plate 310. The arc-shaped surface of one end of the fixing bolt 311 slides into the inner wall of the mounting plate 302. By tightening the fixing bolt 311, it is inserted into the mounting plate 302, and the mounting plate 302 is locked a second time based on the initial positioning of the limiting rod 307, achieving complete fixation and preventing the filter device 3 from loosening due to equipment vibration.

[0037] like Figure 6 - Figure 7As shown, the stirring device 5 includes a motor 51 and two stirring columns 52. The motor 51 is fixedly connected to the regulating tank 1. Both ends of the two stirring columns 52 are slidably connected to the inner wall of the regulating tank 1. One end of one stirring column 52 is fixedly connected to the output end of the motor 51. A synchronous pulley 53 is fixedly connected to one end of each of the two stirring columns 52. The arc surfaces of the two synchronous pulleys 53 are fitted with the same synchronous belt 54. The motor 51 drives one stirring column 52 to rotate, and the synchronous pulley 53 and synchronous belt 54 drive the two stirring columns 52 to rotate synchronously, which fully stirs the ash water in the regulating tank 1, improves the mixing uniformity of the pH adjuster and the ash water, and thus accelerates the stabilization of the pH value. A protective cover 55 is fixedly connected to one side of the regulating tank 1 corresponding to the position of the motor 51. The inner wall of the protective cover 55 is adapted to the size of the motor 51. By setting a protective cover 55 that is adapted to the size of the motor 51, the motor 51 is completely covered, which plays a role in waterproofing and dustproofing, and prevents the ash water from damaging the motor 51. Ventilation pipes 56 are provided on both ends of the protective cover 55. The ventilation pipes 56 are radial. By providing radial ventilation pipes 56 at both ends of the protective cover 55, an effective air convection channel is formed while ensuring that water splashes in, so as to dissipate heat from the motor 51 and prevent the motor 51 from overheating during long-term operation.

[0038] like Figure 8 - Figure 10As shown, the ventilation device 6 includes four hydraulic rods 61 and a suction fan 66. The four hydraulic rods 61 are fixedly connected to the four corners of the upper end of the regulating tank 1. The upper ends of the four hydraulic rods 61 are fixedly connected to the same air collection hood 62. The upper end of the air collection hood 62 is fixedly connected to an air collection pipe 63. A docking assembly 64 is provided at the upper end of the air collection pipe 63. A suction fan 66 is provided at one end of the regulating tank 1. The output end of the suction fan 66 is fixedly connected to a collection pipe 67. The input end of the suction fan 66 is fixedly connected to an air supply pipe 65. One end of the air supply pipe 65 is fixedly connected to the air collection pipe 63 via the docking assembly 64. The docking assembly 64 includes a fixing ring 641 and a docking ring 642. The inner wall of the fixing ring 641... The gas collection hood 62 is fixedly connected to the arc surface of the gas collection pipe 63. Two rotating frames 643 are fixedly connected to the upper two sides of the docking ring 642. The inner wall of the rotating frame 643 has a rotating rod 644. The arc surface of the rotating rod 644 is fixedly connected to a fixing block 646. The cross-section of the fixing block 646 is "U" shaped and the lower end of the fixing block 646 is inclined. The height of the gas collection hood 62 is adjusted by the hydraulic rod 61, and the harmful gas generated in the regulating pool 1 is sucked out by the suction fan 66. At the same time, the "U" shaped fixing block 646 with the inclined lower end can automatically lock the docking ring 642 and the fixing ring 641 under the action of gravity or external force, realizing the rapid and reliable docking of the gas collection pipe 63 and the gas delivery pipe 65. One side of the upper end of the fixed block 646 is inclined. The arc surface of the gas collecting pipe 63 is rotatably connected to the rotating ring 647. The lower ends of the rotating ring 647 are fixedly connected to both sides with fixed pins 648 and pressing rods 649. The arc surface of the fixed pins 648 is slidably connected to the inner wall of the fixed block 646. The lower end of the pressing rods 649 abuts against the surface of the fixed block 646. By rotating the rotating ring 647, the pressing rods 649 are driven to press the upper inclined surface of the fixed block 646, or the fixed pins 648 are driven to exit from the fixed block 646. This realizes the function of unlocking when the rotating ring 647 rotates clockwise and locking the fixed block 646 when it rotates counterclockwise, which facilitates the on / off control of the pipeline. A coil spring 645 is sleeved on the surface of the rotating rod 644. The two ends of the coil spring 645 are fixedly connected to one end of the rotating rod 644 and one side of the fixed block 646, respectively. By setting the coil spring 645 between the rotating rod 644 and the fixed block 646, the torque of the coil spring 645 is used to make the fixed block 646 tend to maintain a clamped state when there is no external force, thereby enhancing the stability and self-locking performance of the docking.

[0039] The overall working principle is as follows: When using this device to adjust the pH of grey water, the grey water first enters the equalization tank 1 through the inlet pipe 2. As the grey water flows through the inlet pipe 2, it directly enters the filter tube 301 of the filter device 3. The filter tube 301 physically intercepts large particles and suspended solids in the grey water. The purified grey water flows through the mesh of the filter tube 301 into the main area of ​​the equalization tank 1, while the impurities are trapped inside the filter tube 301. During this process, because the sealing rings 309 at both ends of the filter tube 301 are tightly fitted to the inner wall of the equalization tank 1 due to the elasticity of the rubber material, unfiltered grey water can be effectively prevented from flowing sideways through the gaps, ensuring the filtration effect.

[0040] Subsequently, based on the real-time monitored pH value, the operator adds an appropriate amount of pH adjuster (acid or alkali) to the equalization tank 1. At this time, the motor 51 of the stirring device 5 is started. The output of the motor 51 drives a fixedly connected stirring column 52 to rotate. The synchronous wheel 53 at the end of the stirring column 52 rotates accordingly, and transmits power to the synchronous wheel 53 at the end of the other stirring column 52 via the synchronous belt 54, thus causing the two stirring columns 52 to rotate synchronously or in opposite directions within the equalization tank 1. The rotation of the two stirring columns 52 generates a strong agitation and mixing effect on the ash water and pH adjuster, causing the adjuster to spread rapidly and evenly, significantly improving the efficiency of the neutralization reaction and thus accelerating the stabilization of the ash water pH value. During the long-term operation of the motor 51, the protective cover 55 completely covers the motor 51 to prevent ash water splashing or humid air from corroding the motor 51. Simultaneously, the radial ventilation pipes 56 at both ends of the protective cover 55 allow external cold air to enter and internal hot air to exit, forming effective convection cooling and preventing the motor 51 from overheating.

[0041] Meanwhile, the ventilation device 6 continues to operate to ensure a safe operating environment. Four hydraulic rods 61 can synchronously extend and retract according to the level of the grey water in the regulating tank 1 or the need for gas collection, adjusting the optimal distance between the gas collection hood 62 and the liquid surface. The gas collection hood 62 collects harmful gases such as ammonia and hydrogen sulfide generated in the regulating tank 1 due to neutralization reactions or the volatilization of the grey water itself, bringing them to its top and conveying them upwards through the gas collection pipe 63. The upper end of the gas collecting pipe 63 is connected to the gas supply pipe 65 via the docking assembly 64. During docking, the docking ring 642 is aligned with the fixing ring 641, and the U-shaped fixing block 646 with its lower inclined surface automatically engages and presses the two together under the action of gravity and the torque of the coil spring 645, achieving a quick and reliable connection. When maintenance or disassembly is required, the operator can rotate the rotating ring 647 counterclockwise. The pressing rod 649 at the lower end of the rotating ring 647 rotates accordingly and presses the inclined surface at the upper end of the fixing block 646, causing the fixing block 646 to open outward against the torque of the coil spring 645. At the same time, the fixing pin 648 exits from the inner wall of the fixing block 646, thereby releasing the lock. The gas supply pipe 65 delivers harmful gases to the input end of the suction fan 66. The suction fan 66 generates negative pressure, forcibly extracting the gas from the gas collecting hood 62 and sending it through the collection pipe 67 at its output end to subsequent treatment equipment such as a spray tower or activated carbon adsorption device for purification and discharge.

[0042] After thorough mixing and pH stabilization, the treated ash water is discharged from the outlet 4 at the lower end of one side of the equalization tank 1, and enters the subsequent process or discharge stage. When the filter device 3 has been used for a period of time, the amount of debris intercepted in the filter tube 301 gradually increases, and the ash water flow rate decreases significantly. The operator can clean it without any tools: pull the limiting rod 307 upward, so that its lower arc surface is dislodged from the first fixing groove 305 of the mounting plate 302, and at the same time, the spring 308 on the limiting rod 307 is compressed; then pull the mounting plate 302 outward, and the sliders 303 on both sides of the mounting plate 302 slide outward along the sliding groove 312 on the inner wall of the equalization tank 1, thereby pulling the entire filter tube 301 out of the equalization tank 1. After cleaning the debris from the filter tube 301, push it in the reverse direction. The slider 303 returns to its original position along the slide groove 312. Release the limiting rod 307, and the spring 308 will push the limiting rod 307 to automatically engage with the first fixing groove 305, achieving initial locking. Finally, tighten the fixing bolt 311 on the fixing plate 310 so that one end of the fixing bolt 311 is inserted into the inner wall of the mounting plate 302, completing the secondary locking and ensuring that the filter device 3 will not loosen under equipment vibration. At this point, the entire greywater pH adjustment process is complete, and the device can be recycled for the next batch of treatment.
