Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to a treatment device for textile dyeing waste liquid. Background Technology

[0002] Textile production generates textile dyeing wastewater, and its treatment is a complex process. Adjusting the pH value is a key step. Dyeing wastewater often has a high pH value and is usually strongly alkaline. Direct discharge can cause secondary pollution to the environment. By adjusting the pH value, the wastewater can be made to a neutral or near-neutral state, reducing the negative impact on the environment. Therefore, it is necessary to adjust the acidity and alkalinity of the wastewater in the neutralization tank to meet the discharge standards.

[0003] In traditional techniques, the pH of dyeing and printing wastewater is often adjusted by adding neutralizing agents to an equalization tank. However, current techniques typically involve selecting an appropriate amount of neutralizing agent based on the wastewater's pH value and adding it all at once to the equalization tank. Then, the agent is left to dissolve slowly in the wastewater. Since the equalization tank is quite large, this concentrated addition prevents the agent from quickly and evenly mixing with the wastewater, resulting in uneven pH adjustment, slow adjustment speed, and low efficiency. Furthermore, it is difficult to control the amount of neutralizing agent added, making precise neutralization difficult. Adding small amounts multiple times further complicates the process and significantly reduces neutralization efficiency.

[0004] Therefore, we propose a treatment device for textile dyeing wastewater to solve the above problems. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this application is to uniformly add neutralizing agents to textile dyeing wastewater, avoiding concentrated addition of neutralizing agents. By uniformly adding and accelerating dissolution, the neutralizing agents are uniformly, quickly, and thoroughly mixed with the wastewater, thereby improving the neutralization effect and efficiency.

The mounting box is fixedly connected to the outer wall of the medicine storage tank. The adjusting plate is fixedly connected to the inner wall of the mounting box.

A sealing groove is provided on the adjusting plate. Two sealing plates are provided and are slidably connected to the sealing groove. A first connecting rod is fixedly connected to one side of the sealing plate, and a second connecting rod is fixedly connected to the other side of the sealing plate. A spring is fixedly connected between the two first connecting rods. The separating block is fixedly connected to the second connecting rod. The electric telescopic rod is fixedly installed inside the mounting box, and the squeezing block is fixedly connected to the output end of the electric telescopic rod.

[0016] Furthermore, the opposite side of the separating block has an angled edge, and the side of the extrusion block that is close to the separating block has an angled edge, and the angled edge of the separating block contacts the angled edge of the extrusion block.

[0017] Furthermore, the dynamic dispensing device is also equipped with an accelerating dispensing device, which includes a connecting ring, a liquid outlet pipe, an accelerating rotating ring, a gear ring, a connecting opening, a second motor, an adjusting gear, a connecting frame, a sliding resistor, an adjusting block, and a moving block.

[0018] One end of the connecting ring is sealed and fixedly connected to the adjusting plate, the liquid outlet pipe is sealed and fixedly connected to the other end of the connecting ring, the accelerating rotating ring is rotatably connected to the connecting ring, the gear ring is fixedly sleeved on the outer wall of the accelerating rotating ring, the connecting opening is opened on one side of the connecting ring, the second motor is fixedly installed in the mounting box, the adjusting gear is fixedly connected to the output shaft of the second motor, the gear ring is meshed and driven by the adjusting gear, the connecting frame is fixedly connected to the top of the connecting ring, the sliding resistor is fixedly installed on the connecting frame, the adjusting block is fixedly connected to the top of one of the sealing plates, the moving block is fixedly connected to the sliding contact of the sliding resistor, and the positions of the adjusting block and the moving block correspond to each other.

[0019] Furthermore, the motor, the sliding resistor, and the power supply are electrically connected.

[0020] Furthermore, a directional guide is provided between the power stirring device and the aeration device, the directional guide including an S-shaped slide rail, a slide groove, a slider and a limiting rod;

[0021] The S-shaped slide rail is fixedly connected to the top of the S-shaped pipe. The slide groove is opened on the S-shaped slide rail. The slider is slidably connected to the slide groove. The limiting rod is fixedly connected to the top of the slider. The rotating shaft is provided with a limiting groove. The limiting rod is rotatably and slidably connected to the rotating shaft through the limiting groove.

[0022] Furthermore, a pH meter is installed on the float, and the pH meter is connected to the electric telescopic rod via a controller.

[0023] Compared to existing technologies, the advantages of this application are:

[0024] (1) By setting up a power stirring device, the first motor drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear and the spur gear to rotate, and the spur gear drives the two stirring rods to rotate in opposite directions to stir and mix the wastewater and neutralizing agent. At the same time, the two stirring rods rotating in opposite directions can act as oars to drive the device to move forward automatically in the regulating tank.

[0025] (2) By setting an aeration device at the bottom of the equalization tank and supplying air to the S-shaped pipe through an air pump, the gas is sprayed out from the vertical nozzle and the inclined nozzle, further mixing the wastewater and neutralizing agent. The gas sprayed from the inclined nozzle is in a different direction than that from the vertical nozzle, which can play a role in turbulence, making the wastewater and neutralizing agent more evenly mixed.

[0026] (3) By setting a dynamic dispensing device on the floating plate, the pH meter detects the pH value of the wastewater in real time. The output shaft of the electric telescopic rod is controlled to extend and retract according to the detected pH value. When the pH is 7, the two sealing plates are in a closed state, blocking the through hole. At this time, no neutralizing agent is added. The higher the pH value, the stronger the alkalinity of the wastewater. The longer the output end of the electric telescopic rod extends, the more the squeezing block moves and squeezes the separation block. The separation block drives the two sealing plates to move up and down to separate them. The size of the through hole is adjusted. The higher the pH value, the farther the two sealing plates are separated, the larger the opening of the through hole, and the greater the amount of neutralizing agent dispensed. Conversely, the lower the pH value, the smaller the amount of neutralizing agent dispensed. This achieves automatic adjustment of the amount of neutralizing agent dispensed.

[0027] (4) By also setting an accelerated dispensing device on the dynamic dispensing device, when the through hole is fully opened, the amount of medicine dispensed has reached the maximum. If the detected pH value continues to increase, the electric telescopic rod will continue to extend, driving the adjusting block to squeeze the moving block to move, thereby moving the sliding contact of the sliding resistor, changing the resistance value of the sliding resistor, and reducing the resistance value. At this time, the current in the circuit will increase, thereby the motor will drive the adjusting gear to rotate, and the adjusting gear will drive the gear ring and the accelerated rotating ring to rotate, accelerating the neutralizing agent, so that the agent flows out faster, thereby further increasing the amount of neutralizing agent dispensed, thereby further improving the neutralization effect and neutralization efficiency.

[0028] (5) By setting a directional guide between the power stirring device and the aeration device, the S-shaped slide rail is laid all over the bottom of the regulating tank. The rotating shaft and the S-shaped slide rail are connected by the limit rod and the slider. When the stirring rod drives the device forward, the slider moves in the S-shaped slide rail to constrain the forward trajectory of the device, so that the movement trajectory of the device can fully cover the entire regulating tank, thereby enabling more comprehensive delivery of neutralizing agent, so that the neutralizing agent can be delivered evenly, avoiding concentrated delivery, and thus improving the neutralization effect.

[0029] (6) By setting up inclined nozzles, on the one hand, the gas ejected from the inclined nozzles is in a different direction than that of the vertical nozzles, which can play a role in turbulence, making the wastewater and neutralizing agent mix more evenly. On the other hand, it can push the slider, further increasing the power of the device to move forward.

[0030] (7) By setting the stirring rod to a shape that is wider on the outside and narrower on the inside, not only is the contact area with the wastewater increased, which can improve the stirring effect, but the shape of the stirring rod can also be made similar to a paddle, which increases the resistance between the stirring rod and the wastewater, thereby improving the forward power of the device.

[0042] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0043] Example 1:

[0044] Please refer to the following: a treatment device for textile dyeing wastewater. Figure 1-9 The system includes an equalization tank 1, within which a float plate 2 is installed. The float plate 2 allows the device to float on the surface of the wastewater. A power agitator 3 is installed on the float plate 2, which uses an agitator rod 306 to agitate the wastewater, ensuring a more uniform mixture of wastewater and neutralizing agent. This agitator also provides power for the device's movement within the equalization tank 1, allowing it to move forward while agitating. The power agitator 3 includes a motor 301, a bevel gear 302, a bevel gear 303, a spur gear 304, a rotating shaft 305, and an agitator rod 306. The motor 301 is fixedly mounted on the float plate 2. The bevel gear 302 is coaxially and fixedly connected to the output shaft of the motor 301. The bevel gear 303 meshes with the bevel gear 302. The transmission connection includes four spur gears 304 that mesh with each other and are rotatably connected to the float plate 2. A bevel gear 303 is coaxially and fixedly connected to one of the spur gears 304. Two rotating shafts 305 are provided and pass through the float plate 2. The two rotating shafts 305 are coaxially and fixedly connected to two spur gears 304 near the two ends, respectively. The stirring rod 306 is fixedly connected to the rotating shafts 305. The stirring rod 306 is designed with a shape that is wider on the outside and narrower on the inside. This not only increases the contact area with the wastewater and improves the stirring effect, but also makes the shape of the stirring rod 306 resemble a paddle, increasing the resistance between the stirring rod and the wastewater, thereby increasing the forward power of the device.

[0045] Motor 301 drives bevel gear 302 to rotate, bevel gear 302 drives bevel gear 303 and spur gear 304 to rotate, and spur gear 304 drives two stirring rods 306 to rotate in opposite directions to stir and mix the wastewater and neutralizing agent. At the same time, the two stirring rods 306 rotating in opposite directions can act as oars to drive the device to move forward automatically in the regulating tank 1.

[0046] An aeration device 4 is installed at the bottom of the equalization tank 1. By aerating from the bottom of the tank, the wastewater and neutralizing agent can be further mixed, making the mixture more uniform. The aeration device 4 includes an S-shaped pipe 401, a vertical nozzle 402, and an inclined nozzle 403. The S-shaped pipe 401 is fixedly installed at the bottom of the equalization tank 1. The vertical nozzle 402 is located on the side of the S-shaped pipe 401, and the inclined nozzle 403 is located on the top of the S-shaped pipe 401. Both the vertical nozzle 402 and the inclined nozzle 403 are connected to the S-shaped pipe 401. The S-shaped pipe 401 is connected to an air pump. The air pump is existing technology and is not shown in the figure. It will not be described in detail here. The inclined nozzle 403 is oriented in the same direction as the forward direction of the power stirring device 3, which can push the slider 703 and further increase the forward power of the device.

[0047] Air is pumped into the S-shaped pipe 401, causing the gas to be ejected from the vertical nozzle 402 and the inclined nozzle 403, further mixing the wastewater and neutralizing agent. The gas ejected from the inclined nozzle 403 is in a different direction than that from the vertical nozzle 402, which can play a turbulent role, making the wastewater and neutralizing agent mix more evenly.

[0048] The floating plate 2 is also equipped with a dynamic dosing device 5, which uses a pH meter 8 to detect the wastewater and automatically adjusts the dosage of the reagent based on the detected pH value, so that the wastewater can be neutralized more evenly. The dynamic dosing device 5 includes a storage tank 501, an inlet 502, an outlet 503, a mounting box 504, an adjusting plate 505, a sealing chute 506, a sealing plate 507, a first connecting rod 508, a second connecting rod 509, a spring 510, a separating block 511, an electric telescopic rod 512, and a squeezing block 5. 13; The medicine storage tank 501 is fixedly connected to the top of the float 2. The feed inlet 502 is located at the top of the medicine storage tank 501 and is connected to the feeding device, which can automatically replenish the medicine into the medicine storage tank 501. The discharge outlet 503 is located at the bottom of the medicine storage tank 501. The mounting box 504 is fixedly connected to the outer wall of the medicine storage tank 501. The adjusting plate 505 is fixedly connected to the inner wall of the mounting box 504. The adjusting plate 505 has a through hole in the middle. The discharge outlet 503 passes through the mounting box 504 and communicates with the through hole, sealing the sliding... The groove 506 is formed on the adjusting plate 505. Two sealing plates 507 are provided and are slidably connected to the sealing groove 506. Connecting rod 1 508 is fixedly connected to one side of the sealing plate 507, and connecting rod 2 509 is fixedly connected to the other side of the sealing plate 507. A spring 510 is fixedly connected between the two connecting rods 1 508. A separating block 511 is fixedly connected to connecting rod 2 509. An electric telescopic rod 512 is fixedly installed inside the mounting box 504. A pressing block 513 is fixedly connected to the output end of the electric telescopic rod 512. The separation block 511 has an angled side facing away from the separation block 511, and the squeezing block 513 has an angled side close to the separation block 511. The angled side of the separation block 511 contacts the angled side of the squeezing block 513. A pH meter 8 is installed on the float plate 2. The pH meter 8 is connected to the electric telescopic rod 512 through a controller. The pH meter 8 can detect the pH value of the wastewater and send the detected signal to the processor. The processor controls the electric telescopic rod 512 to extend and retract, thereby realizing the automatic adjustment of the dosage.

[0049] pH meter 8 detects the pH value of wastewater in real time. Based on the detected pH value, it controls the output shaft of electric telescopic rod 512 to extend and retract. When the pH is 7, the two sealing plates 507 are in a closed state, blocking the through hole. At this time, no neutralizing agent is added. The higher the pH value, the stronger the alkalinity of the wastewater. The longer the output end of electric telescopic rod 512 extends, the more the squeezing block 513 moves to squeeze the separation block 511. The separation block 511 causes the two sealing plates 507 to move up and down to separate, adjusting the size of the through hole. The higher the pH value, the farther the two sealing plates 507 separate, the larger the opening of the through hole, and the greater the amount of neutralizing agent dispensed. Conversely, the lower the pH value, the smaller the amount of neutralizing agent dispensed, thus achieving automatic adjustment of the amount of neutralizing agent dispensed.

[0050] The dynamic dispensing device 5 is also equipped with an accelerating dispensing device 6. After the through hole is fully opened, it can drive the agent to rotate, thereby increasing the flow rate of the agent and further increasing the amount of agent dispensed. The accelerating dispensing device 6 includes a connecting ring 601, a liquid outlet pipe 602, an accelerating rotating ring 603, a gear ring 604, a connecting opening 605, a motor 606, an adjusting gear 607, a connecting frame 608, a sliding resistor 609, an adjusting block 610, and a moving block 611. One end of the connecting ring 601 is sealed and fixedly connected to the adjusting plate 505, the liquid outlet pipe 602 is sealed and fixedly connected to the other end of the connecting ring 601, the accelerating rotating ring 603 is rotatably connected to the connecting ring 601, the gear ring 604 is fixedly sleeved on the outer wall of the accelerating rotating ring 603, and the connecting opening 605 is opened in the connecting ring 601. On one side of 01, motor 2 606 is fixedly installed in mounting box 504. Adjusting gear 607 is fixedly connected to the output shaft of motor 2 606. Gear ring 604 is meshed with adjusting gear 607 for transmission. Connecting bracket 608 is fixedly connected to the top of connecting ring 601. Sliding resistor 609 is fixedly installed on connecting bracket 608. Adjusting block 610 is fixedly connected to the top of one of the sealing plates 507. Moving block 611 is fixedly connected to the sliding contact of sliding resistor 609. The positions of adjusting block 610 and moving block 611 correspond. Motor 2 606, sliding resistor 609 and power supply are electrically connected. It should be noted that when moving block 611 is at the bottom, the resistance of sliding resistor 609 is at its maximum and the current is extremely small, so the accelerating rotating ring 603 cannot rotate.

[0051] Once the through-hole is fully opened, the drug output reaches its maximum. If the detected pH value continues to increase, the electric telescopic rod 512 extends further, causing the adjusting block 610 to press the moving block 611, which in turn moves the sliding contact of the sliding resistor 609, changing its resistance value and reducing it. This increases the current in the circuit, causing the motor 606 to drive the adjusting gear 607 to rotate. The adjusting gear 607 then drives the gear ring 604 and the accelerating rotating ring 603 to rotate, accelerating the neutralizing agent and causing it to flow out faster. This further increases the output of the neutralizing agent, thereby improving the neutralization effect and efficiency.

[0052] A directional guide 7 is provided between the power stirring device 3 and the aeration device 4, which can guide the device to move forward within a specified path, thereby enabling more uniform and comprehensive detection and dosing of chemicals in the entire regulating tank 1. The directional guide 7 includes an S-shaped slide rail 701, a chute 702, a slider 703, and a limiting rod 704. The S-shaped slide rail 701 is fixedly connected to the top of the S-shaped pipe 401, the chute 702 is opened on the S-shaped slide rail 701, the slider 703 is slidably connected to the chute 702, the limiting rod 704 is fixedly connected to the top of the slider 703, and a limiting groove is opened on the rotating shaft 305. The limiting rod 704 is rotatably and slidably connected to the rotating shaft 305 through the limiting groove.

[0053] The S-shaped slide rail 701 covers the bottom of the regulating tank 1. The rotating shaft 305 and the S-shaped slide rail 701 are connected by the limiting rod 704 and the slider 703. When the stirring rod 306 moves the device forward, the slider 703 moves in the S-shaped slide rail 701 to constrain the forward trajectory of the device, so that the movement trajectory of the device can fully cover the entire regulating tank 1. This allows for more comprehensive and even distribution of the neutralizing agent, avoiding concentrated distribution and thus improving the neutralization effect.

[0054] Working principle:

[0055] Turn on motor 301 and air pump. Motor 301 drives bevel gear 302 to rotate. Bevel gear 302 drives bevel gear 303 and spur gear 304 to rotate. Spur gear 304 drives two stirring rods 306 to rotate in opposite directions, stirring and mixing the wastewater and neutralizing agent. At the same time, the two stirring rods 306 rotating in opposite directions can act as oars to drive the device forward automatically in the regulating tank 1. Air is introduced into the S-shaped pipe 401 through the air pump, so that the gas is sprayed out from the vertical nozzle 402 and the inclined nozzle 403, further mixing the wastewater and neutralizing agent. The gas sprayed from the inclined nozzle 403 is in a different direction than that from the vertical nozzle 402, which can play a turbulence role, making the wastewater and neutralizing agent more evenly mixed.

[0056] Since the S-shaped slide rail 701 covers the bottom of the regulating tank 1, the rotating shaft 305 and the S-shaped slide rail 701 are connected by the limiting rod 704 and the slider 703. This allows the stirring rod 306 to constrain the forward trajectory of the device by the movement of the slider 703 in the S-shaped slide rail 701 when it drives the device forward. This ensures that the movement trajectory of the device can fully cover the entire regulating tank 1, thereby allowing for more comprehensive and even distribution of the neutralizing agent. This avoids concentrated distribution and improves the neutralization effect.

[0057] During the movement of the device, the pH value of the wastewater is detected in real time by pH meter 8, and the detected signal is sent to the processor. The processor controls the electric telescopic rod 512 to extend and retract. When the pH is 7, the two sealing plates 507 are in a closed state, blocking the through hole. At this time, no neutralizing agent is added. The higher the pH value, the stronger the alkalinity of the wastewater. The longer the output end of the electric telescopic rod 512 extends, the more the extrusion block 513 moves to squeeze the separation block 511. The separation block 511 causes the two sealing plates 507 to move up and down to separate, adjusting the size of the through hole. The higher the pH value, the farther the two sealing plates 507 are separated, the larger the opening of the through hole, and the greater the amount of neutralizing agent produced. Conversely, the lower the pH value, the smaller the amount of neutralizing agent produced, thus realizing the automatic adjustment of the amount of neutralizing agent produced.

[0058] Once the through-hole is fully opened, the drug output reaches its maximum. If the detected pH value continues to increase, the electric telescopic rod 512 extends further, causing the adjusting block 610 to press the moving block 611, which in turn moves the sliding contact of the sliding resistor 609, changing its resistance value and reducing it. This increases the current in the circuit, causing the motor 606 to drive the adjusting gear 607 to rotate. The adjusting gear 607 then drives the gear ring 604 and the accelerating rotating ring 603 to rotate, accelerating the neutralizing agent and causing it to flow out faster. This further increases the output of the neutralizing agent, thereby improving the neutralization effect and efficiency.
