[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 6 As shown in the figure, a specific embodiment of the present invention discloses an industrial wastewater treatment tank, including a tank body 100. One end of the tank body is connected to an inlet pipe at the top, and the other end is connected to a drain pipe at the bottom. A feeding port 110 is provided at the top of the tank body 100, and a feeding device 200 is provided above the feeding port 110. A first feeding roller 210 and a second feeding roller 220 are provided at the discharge channel 230 of the feeding device 200. A [missing information - likely a specific configuration] is formed between the discharge channel 230, the first feeding roller 210, and the second feeding roller 220. A clamping cavity 240 is used for temporarily storing materials; a collecting trough 120 is provided below the feeding port 110, and a discharge port 130 is provided at the bottom of the collecting trough 120; a baffle 300 is provided inside the collecting trough 120 to block and obstruct the discharge port; a stirring structure 400 is provided below the collecting trough 120, and the stirring structure 400, the first discharge roller 210, and the second discharge roller 220 are all driven to rotate by a motor 500. The rotating stirring structure can move the baffle, causing the material inside the collecting trough to fall out.

[0033] The aforementioned industrial wastewater treatment pond and its treatment method utilize multiple barriers formed by the first feeding roller, the second feeding roller, and the baffle to effectively reduce the entry of moisture into the discharge area, prevent clumping, and avoid blockage. During feeding, the motor drives the first feeding roller to rotate, first discharging the agent into the clamping cavity, and then rotating the first feeding roller to seal the position. Next, the motor drives the second feeding roller to rotate, causing the agent to fall into the discharge trough, and then rotating the second feeding roller to the sealing position. During the rotation of the stirring structure driven by the motor, the baffle is pushed open, causing the internal agent to fall out, thus realizing the dispensing of the agent. Through multiple barriers and gradual dispensing, the duration of conduction is minimized, effectively reducing the entry of moisture into the discharge channel and preventing clumping and blockage.

[0034] Furthermore, such asFigures 4 to 6 As shown, the feeding device 200 includes a hopper 250, a first feeding roller 210, and a second feeding roller 220. The bottom of the hopper 250 narrows towards the center on both sides, and a discharge channel 230 is provided at the bottom of the narrowing point. The discharge channel extends into the interior of the pool through the feeding port. The two side walls of the discharge channel 230 are provided with two sets of opposing grooves 231. The grooves are arc-shaped and their diameters are adapted to the diameters of the first feeding roller 210 and the second feeding roller 220. The first feeding roller and the second feeding roller are rotatably mounted at the discharge channel and are respectively placed in the corresponding grooves. The first feeding roller 210 is located above the second feeding roller 220. The inner wall of the discharge channel, the first feeding roller, and the second feeding roller form the clamping cavity. The outer wall of the first feeding roller 210 is provided with a first material groove 211, and the outer wall of the second feeding roller 220 is provided with a second material groove 221. The motor can drive the first feeding roller and the second feeding roller to rotate independently.

[0035] The first and second feeding rollers form a double barrier inside the discharge channel to prevent moisture from entering the hopper. The resulting cavity can serve as a temporary storage area for the medicine. The medicine in the hopper can be fed into the cavity by first rotating the first feeding roller, and the blocking effect of the first feeding roller is maintained, unaffected by the feeding action below, thus maintaining at least one layer of sealing. Then, the second feeding roller is rotated to feed the medicine. Of course, the second feeding roller also forms an effective barrier with the corresponding groove, which can also prevent moisture from entering the cavity. Even if moisture adheres to the second feeding roller and comes into contact with the medicine during the feeding process, the rotation of the second feeding roller can effectively prevent the formation of clumps.

[0036] Furthermore, at least one end of the discharge channel is open, and a cover plate is installed on the outside of the open end. The cover plate has corresponding holes for the rotating shafts of the first and second discharge rollers. It adopts a detachable and split structure, which makes it easy to detach and assemble the first and second discharge rollers.

[0037] Furthermore, a first magnet is embedded in the end face of the first feeding roller, a second magnet is embedded in the end face of the second feeding roller, and a third magnet is embedded in the end face of the discharge channel and the wall of the cover plate. The first and second feeding rollers can be kept in their respective positions by magnetic attraction and will not easily rotate when no external force is applied. The first and second feeding rollers slide and seal with the corresponding grooves, and can provide a certain rotational damping to maintain an effective sealing fit, prevent the powder from falling easily, and prevent moisture from rising and affecting the storage of the medicine.

[0038] Furthermore, a first pulley, a first electromagnetic clutch, and a second electromagnetic clutch are mounted on the output shaft of the motor. A second pulley is mounted on the follower plate of the first electromagnetic clutch, and a third pulley is mounted on the follower plate of the second electromagnetic clutch. A fourth pulley is mounted on the rotating shaft of the stirring structure, a fifth pulley is mounted on the rotating shaft of the first feeding roller, and a sixth pulley is mounted on the rotating shaft of the second feeding roller. The first and fourth pulleys are connected by a first synchronous belt; the second and fifth pulleys are connected by a second synchronous belt; and the third and sixth pulleys are connected by a third synchronous belt. Through the above-mentioned transmission connections, either the first or second feeding roller can be driven to rotate independently, thus achieving the required blocking effect.

[0039] Furthermore, it also includes a pH sensor, a liquid level sensor, and an electrical control box. The pH sensor probe extends into the tank body and is close to the bottom to monitor the pH value of the wastewater inside, so as to determine whether to continue adding neutralizing materials. The liquid level sensor is used to monitor the amount of wastewater inside and determine whether to discharge it. The pH sensor, liquid level sensor, motor, first electromagnetic clutch, and second electromagnetic clutch are all electrically connected to the electrical control box, which controls each structural component to achieve coordinated operation of each component. It should be noted that the pH sensor, electromagnetic clutch, and electrical control box are all common electrical components and can be purchased and used directly on the market, so they will not be described in detail. It should also be pointed out that the corresponding program can be set according to actual needs, and the neutralization treatment can be carried out by intermittent addition of chemicals, which is suitable for production applications that produce wastewater continuously.

[0040] Furthermore, such as Figures 5 to 8 As shown, the bottom inner wall of the collecting trough 120 has an arc-shaped structure. The baffle 300 includes an arc-shaped baffle 310, the outer diameter of which is adapted to the diameter of the bottom inner wall of the collecting trough 120. Symmetrical material passages 320 are provided on both sides of the baffle 310, and the minimum distance between the two material passages 320 is wider than the width of the discharge port 130. When the baffle is not subjected to external force, the bottom of the baffle blocks and seals the discharge port. A lever 330 is fixedly provided in the middle of the outer arc surface of the baffle 310, and the lever 330 extends out of the bottom of the collecting trough 120 through the discharge port. The rotating stirring structure can push the lever, causing the material passage to move to the same position as the discharge port. With this structure, the baffle can act as a switch for the discharge port, and the blocking and discharge can be achieved by adjusting the position of the baffle. Especially when the stirring structure is not rotating, the baffle maintains the position of blocking the discharge port, effectively preventing the entry of moisture from below.

[0041] Furthermore, the two ends of the baffle are fixed to the circular plate, which rotates and abuts against the end face of the material collection trough and is connected by bolts. The circular plate further strengthens the rotational engagement with the material collection trough and also prevents the baffle from detaching from the rotational engagement part.

[0042] Furthermore, a guide block 340 is fixedly provided on the inner wall of the baffle 310. The cross-section of the guide block is triangular, and the bottom ends of the two inclined surfaces extend to the edge of the feed port. This effectively prevents the agent from being retained inside the baffle and ensures that the agent is completely discharged during the back-and-forth swinging of the baffle.

[0043] Furthermore, the connection between the deflector and the guide block is provided with through holes at both ends, and a counterweight is fixedly embedded in the through holes so that the center of the whole is close to the bottom position. When the stirring structure is disengaged from the deflector, the baffle can swing back smoothly to the state of blocking the discharge port.

[0044] Furthermore, such as Figure 3 , Figure 6 As shown, the stirring structure 400 includes a first rotating shaft 410, a stirring frame 420 is installed on the outer side of the first rotating shaft 410, and at least one pusher plate 430 is installed on the outer wall of the stirring frame 420. When the baffle is in the position of blocking the discharge port, the distance from the bottom end of the baffle plate to the first rotating shaft is less than the maximum distance from the end of the pusher plate to the first rotating shaft. When the baffle is in the position where the feed port and the discharge port are connected, the distance from the bottom end of the baffle plate to the first rotating shaft is greater than the maximum distance from the end of the pusher plate to the first rotating shaft. With this structural design, when the pusher plate pushes the baffle plate during the rotation of the stirring structure, it will drive the baffle to rotate and stir to a certain extent, and the agent on the corresponding side inside will fall from the feed port and the discharge port. Subsequently, when the stirring structure reverses, the agent on the other side will fall and be discharged. Furthermore, the outer side of the mixing rack is provided with at least one slot, which is a T-shaped slot or a dovetail slot structure. The bottom of the lever plate is locked in the slot and fixedly connected by bolts. The detachable structure facilitates the processing and production of each structural component and also facilitates disassembly and replacement.

[0045] Furthermore, the push plate is equipped with multiple through holes penetrating both walls, which can fully agitate the wastewater during rotation, allowing the wastewater to fully contact and mix with the added reagents, thus achieving neutralization treatment.

[0046] This invention also discloses a method for treating industrial wastewater in a treatment pond, comprising the following steps:

[0047] S1, add temporary treatment agent to the hopper;

[0048] S2, according to the set program, starts, adds the agent and mixes, and treats the wastewater inside the tank;

[0049] The application of the pesticide includes the following steps:

[0050] B1, motor starts;

[0051] B2, the first electromagnetic clutch is energized, driving the first feeding roller to rotate a preset number of times, causing the medicine to fall into the clamping cavity; after the number of rotations is reached, the first electromagnetic clutch is de-energized, and the first material trough stops in the position with the trough opening facing upward;

[0052] B3, the second electromagnetic clutch is energized, driving the second feeding roller to rotate a preset number of times, and the medicine falls from the clamping cavity into the collection trough below; after the number of rotations is reached, the medicine inside the clamping cavity is emptied, the second electromagnetic clutch is de-energized, and the second material trough stops in the position with the trough opening facing upward.

[0053] B4. Enter the mixing program. The motor drives the mixing structure to rotate counterclockwise and clockwise in groups of 5 revolutions, alternating until the entire mixing program is completed.

[0054] During the process from B1 to B3, the motor continuously drives the stirring structure to rotate. The stirring structure intermittently pushes the baffle plate, causing the material stop to move, thus causing the agent inside the collection tank to fall below.

[0055] The settings of steps B2 and B3 can minimize the duration of communication between the hopper and the cavity and the interior of the tank, thus effectively preventing moisture from entering the cavity and hopper and preventing moisture from contacting the agent in this area and causing agglomeration. Furthermore, the diameter of the fourth pulley can be increased and the transmission ratio reduced, so that the number of rotations of the motor is less than the number of rotations of the stirring structure. This reduces the number of times the stirring structure actuates the material blocking parts when the motor drives the first and second discharge rollers to rotate, thereby reducing the number of times and the duration of communication between the collection trough and the interior of the tank, further preventing agglomeration.

[0056] This invention has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. This invention is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims are also within the protection scope of this invention.
