The harmful microorganisms, organic pollutants and heavy metal ions in the wastewater are further purified by the purification assembly 4, and finally the purified water is discharged from the purification box body 1 through the drain pipe 12 and transported to the designated pipeline.

[0034] The vertical wall surface of the purification box 1 is provided with a water inlet pipe 11 above the cleaning mechanism 3, and is further provided with a drain pipe 12 below the purification assembly 4. The vertical wall surface of the purification box 1 corresponding to the recovery mechanism 5 is provided with a discharge port 13, the horizontal height of the bottom surface of the discharge port 13 is equal to the horizontal height of the top surface of the filter plate 35, which ensures that the precipitated crystalline impurities on the filter plate 35 can be pushed out of the purification box 1 by the cleaning plate assembly 34, and the vertical side wall surface of the purification box 1 corresponding to the activated carbon tank 42 is provided with a through groove 14 for accommodating the sliding of the activated carbon tank 42, which provides the implementation condition for taking out and replacing new activated carbon, further ensures the water purification effect, and the through groove 14 is hingedly connected with a sealing door 15 matched in size, and a sealing gasket can be arranged on the inner side of the sealing door 15 to prevent water in the purification box 1 from leaking out, thereby improving the sealing effect;

The stirrer 23 includes a mounting ring sleeved outside the rotating shaft 22, and a plurality of stirring blades are uniformly distributed on the outer side of the mounting ring in a radial manner. A plurality of perforations are uniformly formed on the stirring blades to accelerate the rotation speed of the stirring blades. When the motor 21 is started, the motor 21 drives the rotating shaft 22 to rotate, and the rotating shaft 22 drives the stirrer 23 to rotate, thereby accelerating the mixing speed of the medicament and the wastewater, improving the crystallization of the soluble impurities in the wastewater, and further improving the water purification speed. The impurity crystals fall on the filter plate 35, and then are pushed to the discharge port 13 by the cleaning plate assembly 34, and then fall into the recovery mechanism 5;

[0036] Specifically, the cleaning mechanism 3 comprises a screw rod 32 rotatably installed between the opposite vertical inner wall surfaces of the purification box body 1 and arranged in parallel with the rotating shaft 22, one end of the screw rod 32 penetrates the purification box body 1 to the outside and is coaxially fixedly connected with the output shaft of the servo motor 31 fixed on the outer side wall of the purification box body 1, the outer side of the screw rod 32 is threadedly sleeved with a sliding rod 33, the bottom surface of the sliding rod 33 is provided with a cleaning plate assembly 34, the bottom end of the cleaning plate assembly 34 abuts against a filter plate 35 fixedly installed on the vertical inner wall surface of the purification box body 1, the cleaning plate assembly 34 comprises an inverted L-shaped cleaning plate 341 fixedly connected with the bottom surface of the sliding rod 33 and slidingly abutting against the top surface of the filter plate 35, the horizontal section of the L-shaped cleaning plate 341 is arranged towards the discharge port 13, the vertical section of the L-shaped cleaning plate 341 is provided, on the side close to the discharge port 13, with a first electric push rod 342 and a telescopic rod 343 arranged side by side, the telescopic rod end of the first electric push rod 342 and the telescopic rod end of the telescopic rod 343 are fixedly provided with a same moving cleaning plate 344, when the crystalline impurities on the filter plate 35 need to be cleaned, the servo motor 31 is started, the servo motor 31 drives the screw rod 32 to rotate, the screw rod 32 drives the sliding rod 33 to slide towards the discharge port 13, at this time, the cleaning plate assembly 34 pushes the crystalline impurities to move towards the discharge port 13, when the L-shaped cleaning plate 341 in the cleaning plate assembly 34 enters the discharge port 13, the infrared sensor 6 senses the impurity crystalline body and sends a signal to the PLC controller 7, then the PLC controller 7 sends signals to the second electric push rod 521 and the first electric push rod 342 respectively, after receiving the signal, the second electric push rod 521 immediately starts the contraction function, the sealing plate 522 and the sealing gasket 523 are separated from the discharge port 13 to make the discharge port 13 in an open state, then the first electric push rod 342 extends towards the discharge port 13 after receiving the signal, and the moving cleaning plate 344 is pushed forward, finally, the impurity crystalline body enters the recycling mechanism 5 under the pushing of the moving cleaning plate 344.

[0037] Wherein, the stirring blade is not in contact with the screw rod 32, avoiding the mutual influence of the stirring assembly 2 and the cleaning mechanism 3.

[0038] It should be noted that the moving cleaning plate 344 can be accommodated in the L-shaped cleaning plate 341, when the first electric push rod 342 and the telescopic rod 343 are in the longest state or the shortest state, there is always a four-around-enclosed space between the moving cleaning plate 344 and the L-shaped cleaning plate 341, ensuring that there is no gap between the L-shaped cleaning plate 341 and the moving cleaning plate 344, preventing the impurity crystalline body from falling between them and being difficult to be cleaned out of the purification box body 1, thereby affecting the water purification effect;

[0039] Furthermore, the horizontal height of the top surface of the L-shaped cleaning plate 341 is less than or equal to the horizontal height of the top surface of the discharge port 13. When the L-shaped cleaning plate 341 slides to the closest point to the discharge port 13 and the first electric push rod 342 and the telescopic rod 343 are extended to their longest state, the moving cleaning plate 344 slides into the discharge port 13 to ensure that all the impurity crystals can be discharged from the discharge port 13 to the outside of the purification chamber 1.

[0040] Furthermore, the purification component 4 includes an activated carbon tank 42 that is horizontally slidably inserted into the purification chamber 1. The purification component 4 also includes two mounting crossbars 41 that are fixedly connected to the vertical inner walls opposite to the purification chamber 1 and are symmetrically arranged.

The vertical wall surface of the activated carbon tank 42 corresponding to the through groove 14 is provided with a pull groove 43. The pull groove 43 facilitates the pulling of the activated carbon tank 42. After the wastewater is filtered by the filter plate 35, it falls into the activated carbon tank 42 filled with activated carbon. The activated carbon adsorbs all the harmful microorganisms, organic pollutants and heavy metal ions in the wastewater, thereby achieving the purpose of purifying the wastewater. The purified water flows to the bottom of the purification chamber 1 and is then discharged from the purification chamber 1 through the drain pipe 12 and transported to the designated pipeline.

[0041] Finally, the outer wall of the purification box 1 in the sliding direction of the slide bar 33 is provided with a recycling mechanism 5 connected thereto. The recycling mechanism 5 includes a recycling box 51 fixedly connected to the purification box 1.

The recycling box 51 is provided with a sealing plug assembly 52 that extends and retracts toward the discharge port 13. The center point of the sealing plug assembly 52 and the discharge port 13 are at the same height. The design of the sealing plug assembly 52 can realize the selection of whether to seal the internal space of the purification box 1 according to actual needs, making the structural device more flexible.

[0042] It should be further explained that the sealing plug assembly 52 includes a second electric push rod 521. The telescopic rod end of the second electric push rod 521 is provided with a sealing plate 522. The sealing plate 522 is adapted to the size of the discharge port 13. A sealing gasket 523 is provided on the side wall of the sealing plate 522 near the discharge port 13. When the purification box 1 needs to be a sealed space, the sealing gasket 523 can improve its sealing effect. When the second electric push rod 521 is extended to its longest state, the sealing plate 522 moves into the discharge port 13, ensuring that the sealing plug assembly 52 can block the discharge port 13. When the second electric push rod 521 is retracted to its shortest state, there is a distance of more than 10cm between the sealing gasket 523 and the discharge port 13, ensuring that the impurity crystals have enough space to fall from the discharge port 13 into the recycling box 51.

[0043] Further, the inner side wall surface of the purification box 1 is provided with an infrared sensor 6 near the discharge port 13, the outer wall of the recovery box 51 is provided with a PLC controller 7, the infrared sensor 6 is signal connected with the PLC controller 7, the PLC controller 7 is signal connected with the first electric push rod 342 and the second electric push rod 521, and the setting of the infrared sensor 6 and the PLC controller 7 makes the whole device tend to be automated, the cooperation between various structural elements is more intelligent and more accurate than manual operation, and the working efficiency is improved.

[0044] Finally, it should be noted that the motor 21, the servo motor 31, the first electric push rod 342, the second electric push rod 521, the infrared sensor 6 and the PLC controller 7 and other components involved in the utility model are all general standard components or components known to those skilled in the art, the structure and principle of which can be known by the technical personnel through the technical manual or through the conventional experimental method, all the electrical components in the idle place of the device are connected by wires, the power elements, electrical components and the matched controller and power supply are connected, the specific connection means should be referred to the working principle in the utility model, the electrical components are electrically connected according to the working order, and the detailed connection means is the commonly known technology in the art.
