[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1, as Figure 1 and Figure 2 As shown, a corrugated cardboard box production wastewater treatment device includes a shell 1, the four corners of the lower end of the shell 1 are fixedly connected to support legs 2, the front end of the shell 1 is fixedly installed with a control box 4, the upper right part of the shell 1 is fixedly connected to a feed pipe 3, the inner surface of the shell 1 is provided with a filter addition component 5, and the inner surface of the shell 1 is provided with an oil removal component 6 below the filter addition component 5.

[0035] During the implementation of this embodiment, the corrugated box production wastewater enters the inner cavity of the shell 1 through the feed pipe 3, and the control box 4 is operated to make the filter addition component 5 first perform a preliminary filtration operation on the wastewater to remove large suspended matter in the wastewater and reduce the pressure of subsequent equipment treatment. Then, an appropriate amount of coagulant such as (polyferric coagulant) and coagulant aid such as (polymer flocculant PAM) are evenly added to the wastewater, and the wastewater is fully mixed with the coagulant and coagulant aid by stirring. Then, the wastewater is aerated through the oil removal component 6, and the smaller suspended matter and ink in the wastewater are brought to the surface of the wastewater for removal by the action of bubbles. The wastewater will precipitate to form flocs under the action of the coagulant and coagulant aid, and finally separated.

[0036] The above-mentioned wastewater can be further treated through biochemical treatment equipment and deep treatment equipment after physical and chemical pretreatment.

[0037] The control box 4 mentioned above is a mature control technology means and equipment in the prior art. In this solution, its controllable functions are utilized, and its structure, connection method and principle are not further explained.

[0038] Specifically, in order to achieve physical and chemical pretreatment of wastewater, refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 In this embodiment, the filtering and adding component 5 includes a circular hole concave plate 51 fixedly connected to the inner surface of the shell 1, a placement frame 52 is fixedly connected to the inner surface of the shell 1 below the circular hole concave plate 51, a diversion mechanism 53 is symmetrically arranged at the upper end of the circular hole concave plate 51, a filtering mechanism 54 is arranged on the inner surface of the shell 1 below the circular hole concave plate 51, a cleaning mechanism 55 is arranged on the inner surface of the shell 1 above the filtering mechanism 54, a stirring and injection mechanism 56 is arranged in the inner cavity of the placement frame 52, a rectangular hole 58 is opened at the lower part of the rear end of the shell 1, and a collecting frame 57 is movably installed on the inner surface of the rectangular hole 58.

[0039] For further information, see Figure 3 and Figure 5 In this embodiment, the diversion mechanism 53 includes two fixed blocks 531 fixedly connected to the upper end of the circular hole concave plate 51, the inner surfaces of the two fixed blocks 531 are connected to a blocking block 532 for rotation together, the upper end of the blocking block 532 is fixedly connected to a pull rope 533, and the end of the pull rope 533 away from the blocking block 532 is fixedly connected to a buoyancy plate 534.

[0040] During the implementation process, the wastewater entering through the feed pipe 3 will fall on the circular hole concave plate 51 under the action of gravity. As the wastewater level continues to rise, the buoyancy plate 534 will be driven to move upward continuously so that the pull rope 533 can be tightened. The continuous movement of the buoyancy plate 534 causes the blocking block 532 to rotate on the inner surface of the fixed block 531, opening the circular hole on the circular hole concave plate 51. The wastewater will fall evenly through the four circular holes under the action of gravity, which will be diverted for subsequent filtration to reduce the pressure of subsequent filtration, fully separate the large suspended matter in the wastewater, and at the same time control the amount of wastewater treated each time.

[0041] For further information, see Figure 3 and Figure 6 In this embodiment, the filtering mechanism 54 includes a W-shaped filter screen 541 fixedly connected to the lower end of the circular hole concave plate 51 and the inner surface of the shell 1, and a spring telescopic rod 544 is fixedly connected to the rear of the inner surface of the shell 1 symmetrically on the left and right, and the front ends of the two spring telescopic rods 544 are fixedly connected to an extrusion plate 545, and the front ends of the extrusion plate 545 are fixedly connected to a rubber strip 543, and the rear end of the W-shaped filter screen 541 is provided with a placement groove 542 that is compatible with the size and shape of the outer surface of the rubber strip 543.

[0042] For further information, see Figure 3 and Figure 6 In this embodiment, the cleaning mechanism 55 includes a reciprocating rod 552 that penetrates the front end of the shell 1 and extends to the rear end of the extrusion plate 545 and is rotatably connected. The front end of the reciprocating rod 552 is fixedly connected to a dual-axis motor 551 that is fixedly connected to the front end of the shell 1. The outer surface of the reciprocating rod 552 is slidably connected to a scraper 553 that is tightly attached to the upper part of the outer surface of the W-shaped filter screen 541. The rear end of the scraper 553 is symmetrically fixedly connected to an extrusion block 554.

[0043] During the implementation process, the wastewater falling through the diversion mechanism 53 will fall into the depression of the W-shaped filter 541. The large suspended matter in the wastewater will be retained in the depression under the action of the W-shaped filter 541. At the same time, the subsequent wastewater will not be blocked when falling and can still fall through both sides of the W-shaped filter 541. The filtered wastewater will fall into the placement frame 52. Then, the rear end output end of the dual-axis motor 551 is started to drive the reciprocating rod 552 to rotate through the coupling. Since the reciprocating rod 552 and the scraper 553 are in sliding connection, The reciprocating rod 552 drives the scraper 553 to move during the rotation, so that the lower end of the scraper 553 scrapes the large suspended matter trapped on the W-shaped filter screen 541. At the same time, the squeezing block 554 on the scraper 553 can squeeze the squeezing plate 545, so that the spring telescopic rod 544 is in a compressed state, and the squeezing plate 545 is gradually moved away from the W-shaped filter screen 541. The large suspended matter will fall into the collection frame 57 under the action of gravity, thereby improving the wastewater treatment efficiency, improving the water quality of the effluent, and facilitating the subsequent further treatment of the wastewater.

[0044] The reciprocating rod 552 and the scraper 553 mentioned above constitute a mature ball screw mechanism in the prior art.

[0045] For further information, see Figure 3 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 In this embodiment, the stirring and injecting mechanism 56 includes a water tank 568 fixedly connected to the left end of the placing frame 52, a partition 561 is fixedly connected to the inner surface of the placing frame 52, a solenoid valve tube 562 is fixedly installed on the lower part of the inner surface of the placing frame 52 and extends to the lower end of the placing frame 52, and the front end of the shell 1 penetrates and extends to the inner surface of the placing frame 52 and is symmetrically rotated and connected to the stirring rod 564, the front end of the double-axis motor 551 is fixedly connected to the transmission rod 563 through a coupling, the front ends of the outer surfaces of the two stirring rods 564 are fixedly connected to the pulley group 1 566, and the outer surface of the transmission rod 563 and the outer surface of the stirring rod 564 located on the right are fixedly connected to the pulley group 2 5 67. A connecting pipe 5610 is fixedly connected to the upper end of the water tank 568 and extends through the upper inner surface of the water tank 568. A metering pump 569 is fixedly connected to the lower end of the connecting pipe 5610. A plurality of connecting holes 5613 are arranged in an annular pattern on the outer surfaces of the two stirring rods 564. A connecting hole 5614 connected to the connecting hole 5613 is arranged on the outer surfaces of the two stirring rods 564. A circular ring block 5612 fixedly connected to the inner surface of the placement frame 52 is rotatably connected to the outer surfaces of the two stirring rods 564 at the connecting hole 5614. The inner surface of the connecting pipe 5610 symmetrically penetrates and extends to the inner surface of the circular ring block 5612 and is fixedly connected to the connecting pipe 2 5611.

[0046] During the implementation process, the wastewater falling into the placement frame 52 will be divided into two areas by the partition 561, and the front output end of the dual-axis motor 551 is started to drive the transmission rod 563 to rotate through the coupling, and under the coordinated transmission action of the pulley group 1 566 and the pulley group 2 567, the two stirring rods 564 are driven to rotate, and at the same time, the metering pump 569 is started to extract the coagulant and coagulant aid mixed in advance from the water tank 568, and enter the inner cavity of the stirring rod 564 through the connecting pipe 1 5610 and the connecting pipe 2 5611 and enter the wastewater through the connecting hole 1 5613. As the stirring rod 564 rotates, the coagulant and coagulant aid can be evenly mixed in the wastewater. The even mixing of the coagulant and the coagulant aid can ensure that they are in full contact with the suspended matter, colloidal substances, etc. in the wastewater, thereby exerting a better coagulation effect and helping to form larger alum flowers or agglomerates, which are easier to separate through subsequent flotation, thereby shortening the time of wastewater treatment and improving the efficiency of the entire wastewater treatment process.

[0047] The metering pump 569 mentioned above is a mature metering extraction means and equipment in the prior art. In this scheme, it is used to quantitatively extract the mixed solution of coagulant and coagulant aid, thereby saving the use of coagulant and coagulant aid. Its structure and principle will not be elaborated again.

[0048] The highest height of the connecting pipe 5610 mentioned above should be higher than the water level of the wastewater during actual use to prevent the wastewater from flowing back.

[0049] The pulley set 1 566 and the pulley set 2 567 mentioned above are both composed of two pulleys and a belt.

[0050] The dual-axis motor 551 mentioned above is a mature driving technology device in the prior art, and is a mature driving technology means in the prior art. This solution utilizes its function of independent rotation on both sides, and its principle, structure and connection method will not be elaborated.

[0051] Embodiment 2: Based on Embodiment 1, this embodiment adds an oil removal component 6 for removing small suspended particles and ink in the wastewater, thereby achieving the purpose of removing small suspended particles and ink in the wastewater.

[0052] Specifically, in order to remove small suspended solids and ink from wastewater, refer to Figure 3 , Fig.10 , Fig.11 and Fig.12In this embodiment, the oil removal assembly 6 includes an inclined groove frame 61 fixedly connected to the inner surface of the outer shell 1, the lower part of the inner surface of the inclined groove frame 61 penetrates and extends to the lower end of the outer shell 1 and is fixedly connected to a sewage pipe 62, the right part of the inner surface of the inclined groove frame 61 penetrates and extends to the right end of the outer shell 1 and is fixedly connected to an overflow pipe 65, an aeration mechanism 63 is arranged at the lower part of the inner surface of the inclined groove frame 61, and an oil removal mechanism 64 is symmetrically arranged at the lower end of the placement frame 52.

[0053] For further information, see Figure 3 , Fig.10 and Fig.11 In this embodiment, the aeration mechanism 63 includes four hollow blocks 631 that penetrate the lower part of the inner surface of the placement frame 52 and extend to the lower end of the placement frame 52 and are fixedly connected in a ring distribution. The inner surfaces of the four hollow blocks 631 are fixedly connected with cross blocks 635. The middle parts of the upper ends of the four cross blocks 635 are fixedly connected with reset springs 636. The upper ends of the four reset springs 636 are fixedly connected with balls 637. The outer surfaces of the four balls 637 are fixedly connected with telescopic nets 638 fixedly connected to the upper ends of the hollow blocks 631. The lower parts of the inner surfaces of the four hollow blocks 631 penetrate and extend to the lower ends of the hollow blocks 631 and are fixedly connected with connecting pipes three 632. The lower ends of the four connecting pipes three 632 are commonly fixedly connected with connecting pipes four 633. One end of the connecting pipe four 633 is fixedly connected with an air compression pump 634 fixedly installed on the inner surface of the outer shell 1.

[0054] For further information, see Figure 3 and Fig.12 In this embodiment, a heating plate 6310 is fixedly installed on the outer surface of the fourth connecting pipe 633, and a plurality of semicircular blocks 639 are fixedly connected to the inner surface of the fourth connecting pipe 633 in a linear and equidistant staggered manner.

[0055] During the implementation process, the wastewater after adding coagulant and coagulant aid falls into the inclined trough frame 61 through the solenoid valve tube 562, and then the air compression pump 634 is started to draw external air into the connecting tube three 632 and the connecting tube four 633 and enter the four hollow blocks 631. Due to the action of the ball 637 and the return spring 636, the air will accumulate in the hollow block 631 and gradually push the ball 637 to move upward, so that the return spring 636 is in a stretched state, and the accumulated air will evenly enter the wastewater through the circular holes on the telescopic net 638, so that the bubbles can drive the smaller particle suspended matter and ink in the wastewater to move upward and float on the surface of the wastewater, which can effectively remove pollutants such as fine suspended matter and grease in the wastewater and improve the treatment effect of the wastewater.

[0056] Secondly, under different ambient temperatures, the air temperature can be heated through the cooperation of the heating plate 6310 and the semicircular block 639, so that the gas injected into the wastewater can be at a suitable temperature, thereby improving the treatment effect and efficiency of the wastewater.

[0057] The heating plate 6310 mentioned above is a mature heating technology means and equipment in the prior art. In this solution, its heating function is utilized, and its principle, structure and connection method are not further explained.

[0058] The solenoid valve tube 562 mentioned above is a mature control technology means and equipment in the prior art. In this solution, its function of controlling the flow direction of wastewater is utilized, and its structure and principle are not further elaborated.

[0059] For further information, see Figure 3 and Fig.12 In this embodiment, the oil removal mechanism 64 includes four connecting ropes 641 fixedly connected to the lower end of the placement frame 52, and the lower ends of the four connecting ropes 641 are commonly fixedly connected to a hollow round block 642. A plurality of leakage holes 643 are arranged in a ring shape on the upper outer surface of the hollow round block 642, and a buoyancy ball 644 is fixedly connected to the upper end of the hollow round block 642. The lower inner surface of the hollow round block 642 penetrates and extends to the rear end of the inclined groove frame 61 and is fixedly connected to a discharge pipe 645.

[0060] During the implementation process, the wastewater will continuously raise the water level after entering the chute frame 61, so that the buoyancy ball 644 can drive the hollow circle block 642 to always be at the water surface, and the middle part of the leakage hole 643 can be at the liquid surface, and then the fine suspended matter and pollutants such as grease floating on the water surface will enter the inner cavity of the hollow circle block 642 through the leakage hole 643, and finally enter the collection frame 57 through the discharge pipe 645. The fine suspended matter and grease in the wastewater are separated and treated, which can significantly reduce the pollutant content in the wastewater and improve the wastewater treatment efficiency. The separated fine suspended matter and grease can be recycled again.

[0061] The discharge pipe 645 mentioned above is made of soft material.

[0062] Working process: when in use, the wastewater can be centrally and quantitatively diverted through the diversion mechanism 53 to reduce the filtering pressure for the W-shaped filter 541 in the subsequent filtering mechanism 54, and the large suspended matter in the wastewater is filtered and retained by the filtering mechanism 54, and then the large suspended matter is cleaned and collected by the cleaning mechanism 55. The treated sewage will enter the placement frame 52 under the action of gravity, and the coagulant and coagulant aid solutions will be evenly mixed in the wastewater through the stirring injection mechanism 56.
