Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of wastewater treatment, and more particularly, to a corrugated paper production wastewater recycling treatment device. Background Art

[0002] Corrugated paper is a multi-layer paper material composed of at least one layer of corrugated core paper in a wavy shape and one or more layers of flat linerboard (also known as facing paper). This unique structure endows corrugated paper with many excellent properties. The wavy shape of the corrugated core paper can increase the buffering capacity of the paper, just like tiny springs, which can effectively disperse pressure when subjected to external forces, while the outer linerboard provides strength and protection to prevent internal items from being collided, rubbed, and squeezed by the outside world; A large amount of wastewater is generated during the production of corrugated paper. This wastewater contains various pollutants, such as fiber suspensions, residues of chemical additives (such as starch, glue, etc.), ink, and other dissolved organic substances. If directly discharged, it will not only cause serious environmental pollution but also result in a great waste of water resources. Therefore, a wastewater treatment device is needed to treat this wastewater; The wastewater treatment devices in the prior art usually only perform single treatment on the wastewater, resulting in incomplete treatment of the wastewater and poor treatment effects. Moreover, the treatment methods for single treatment are relatively single, resulting in incomplete treatment of the wastewater and making it difficult to recycle and reuse the wastewater.

[0022] Such as Figures 1 to 7As shown, it shows a corrugated paper production wastewater recycling treatment device in an embodiment of the present disclosure, including a treatment barrel 1, and also including a stirring mechanism, a packing tray 2, a collecting hopper 3, a filter layer 4, a transmission frame 5, a return mechanism, a vibration motor 6, a return pipeline 7, a circulation pump 8 and an adsorption mechanism. The wastewater treatment devices in the prior art usually only perform single treatment on wastewater, resulting in insufficient comprehensive treatment of wastewater, poor treatment effect, and relatively single treatment method for single treatment, resulting in insufficient comprehensive treatment of wastewater and difficulty in recycling and reusing wastewater. In this embodiment, through the combined use of the stirring mechanism and the packing tray 2, rapid mixing of wastewater and treatment agent is achieved, and the contact time between wastewater and treatment agent is extended, enhancing the treatment effect on impurities in wastewater. Through the combined use of the collecting hopper 3 and the filter layer 4, filtration treatment of the wastewater after primary treatment is achieved, realizing secondary treatment of wastewater, and further enhancing the treatment effect on wastewater. Through the cooperation of the return pipeline 7, the circulation pump 8 and the adsorption mechanism, return and re-treatment of the wastewater after secondary treatment are achieved, realizing circular treatment of wastewater, thereby achieving comprehensive treatment of wastewater, facilitating the recycling and reusing of wastewater. Through the combined use of the transmission frame 5, the return mechanism and the vibration motor 6, vibration of the filter layer 4 inside the collecting hopper 3 is achieved, enhancing the filtration effect of the filter layer 4 on wastewater, reducing the probability of blockage of the filter layer 4 by impurities carried in the wastewater, and ensuring the normal operation of the device.

[0023] As Figure 1 shown, one side of the upper side of the treatment barrel 1 is communicated with a water inlet pipeline 13, and the wastewater generated during the production process of corrugated paper enters the inside of the treatment barrel 1 through the water inlet pipeline 13. The other side of the upper side of the treatment barrel 1 is communicated with a treatment agent adding pipe 14, and the staff can add treatment agent into the inside of the treatment barrel 1 through the treatment agent adding pipe 14, so that the treatment agent can be added synchronously during the wastewater inlet process; As Figure 2 shown, the stirring mechanism is rotatably installed on the inner top wall of the treatment barrel 1, and a driving member for driving the stirring mechanism to rotate is arranged on the upper side of the treatment barrel 1. The driving member is a forward and reverse motor. As Figure 3 shown, the stirring mechanism includes a stirring shaft 101 and stirring rods 102. The stirring rods 102 are arranged obliquely on the stirring shaft 101, and the included angle between the stirring rods 102 and the stirring shaft 101 is 30°. The obliquely arranged stirring rods 102 can better stir and mix wastewater and treatment agent. A plurality of scraping plates 9 are installed on the outer side of the stirring shaft 101. The number of scraping plates 9 is four groups. The outer sides of the scraping plates 9 are abutted against the inner wall of the treatment barrel 1. The scraping plates 9 can scrape the impurities remaining on the inner wall of the treatment barrel 1, reducing the remaining amount of impurities on the inner wall of the treatment barrel 1, thereby ensuring the cleanliness inside the treatment barrel 1. The stirring mechanism can accelerate the mixing speed of wastewater and treatment agent, thereby improving work efficiency; As Figure 2 shown, the packing tray 2 is arranged inside the treatment barrel 1 and below the stirring mechanism. A flow chamber is provided inside the packing tray 2. The wastewater after preliminary treatment can flow in the flow chamber of the packing tray 2 and come into full contact with the packing inside the packing tray 2, so that the packing inside the packing tray 2 can adsorb the harmful substances remaining in the wastewater, thus realizing the adsorption of the harmful substances remaining in the wastewater and enhancing the treatment effect of the wastewater. The collecting hopper 3 is sleeved on the water outlet pipe on the inner bottom wall of the treatment barrel 1. A filter layer 4 is arranged inside the collecting hopper 3. As Figure 6 shown, the filter layer 4 is composed of multiple filter meshes, and the pore diameters of the filter meshes decrease successively from top to bottom. The filter layer 4 can perform secondary filtration on the wastewater after preliminary treatment, thus enhancing the treatment effect of the wastewater. The transmission frame 5 is arranged below the collecting hopper 3 through two groups of return mechanisms. As Figure 5 shown, the return mechanism includes a cylinder body 201, a transmission rod 202, a transmission ring 203 and a return spring 204. As Figure 7 shown, a vibration motor 6 for driving the transmission frame 5 to vibrate is arranged on the transmission frame 5. The combined use of the transmission frame 5, the return mechanism and the vibration motor 6 can drive the filter layer 4 inside the collecting hopper 3 to vibrate, thus accelerating the filtration speed of the filter layer 4 for the wastewater and reducing the probability of the filter meshes inside the filter layer 4 being blocked by impurities in the wastewater; As Figure 1 shown, the reflux pipeline 7 is connected to the outside of the treatment barrel 1. A circulation pump 8 is arranged at the upper part of the reflux pipeline 7, and an adsorption mechanism is arranged at the lower part of the reflux pipeline 7. As Figure 4 shown, the adsorption mechanism includes a treatment tank 301, a mounting ring 302 and an adsorption layer 303. The combined use of the reflux pipeline 7, the circulation pump 8 and the adsorption mechanism realizes the reflux and re-treatment of the treated wastewater, enables the wastewater to be treated cyclically, and the adsorption mechanism can adsorb the harmful substances in the wastewater during the reflux process of the wastewater, so that the wastewater after cyclic treatment can be recycled. As Figure 7As shown in the figure, a drain pipe 10 is connected to the lower side of the treatment barrel 1. The drain pipe 10 is used for recycling and reusing the wastewater after cyclic treatment. A water quality monitor is arranged on the upper part outside the drain pipe 10, and the water quality monitor can detect the water quality of the treated wastewater. A first switch valve 11 is arranged at the lower part of the drain pipe 10, and the first switch valve 11 is used to control the opening and closing of the drain pipe 10. During the cyclic treatment of the wastewater, the first switch valve 11 is in a normally closed state. The bottom end of the reflux pipe 7 is connected to the drain pipe 10. A second switch valve 12 is arranged at the lower part of the reflux pipe 7, and the second switch valve 12 is used to control the opening and closing of the reflux pipe 7. During the cyclic treatment of the wastewater, the second switch valve 12 is in an open state. When the wastewater is recycled and reused through the drain pipe 10, the second switch valve 12 is in a normally closed state.

[0024] Working principle: The wastewater generated during the production process of corrugated paper enters the interior of the treatment barrel 1 through the water inlet pipe 13. During the wastewater inlet process, the staff adds the treatment agent into the interior of the treatment barrel 1 from the treatment agent adding pipe 14. After the treatment agent enters the interior of the treatment barrel 1, it is mixed with the wastewater. At this time, the forward and reverse motor is started, and the forward and reverse motor drives the stirring shaft 101 to rotate. The stirring shaft 101 drives the stirring rods 102 and the scraping plate 9 to rotate. The plurality of stirring rods 102 stir and mix the wastewater and the treatment agent entering the interior of the treatment barrel 1, and the scraping plate 9 scrapes the impurities splashed on the inner wall of the treatment barrel 1, thereby accelerating the mixing speed of the wastewater and the treatment agent and realizing the preliminary treatment of the wastewater. The preliminarily treated wastewater flows through the packing tray 2, and the wastewater flows in the flow chamber inside the packing tray 2. At this time, the packing inside the packing tray 2 adsorbs the chemical substances in the wastewater, realizing the adsorption of the residual chemical substances in the wastewater after preliminary treatment. Then, the wastewater flows into the collection hopper 3. When the wastewater flows through the filter layer 4, the plurality of filter meshes inside the filter layer 4 filter the residual impurities in the wastewater. During the filtering process, the vibration motor 6 is started, and the operation of the vibration motor 6 drives the transmission frame 5 to vibrate. The transmission frame 5 drives the transmission ring 203 to move vertically inside the cylinder 201 through the transmission rod 202. The transmission ring 203 compresses or stretches the two return springs 204. The transmission rod 202 drives the collection hopper 3 to move vertically along the water outlet pipe. The return spring 204 can drive the collection hopper 3 to return through the transmission rod 202 and the transmission ring 203, so that the collection hopper 3 drives the filter layer 4 to vibrate and shake, thereby accelerating the filtering speed of the filter layer 4 for the wastewater and reducing the probability of the filter meshes inside the filter layer 4 being blocked by impurities. The wastewater after filtration treatment flows into the interior of the drainage pipe 10 through the outlet pipe. At this time, the water quality monitor set on the drainage pipe 10 detects the water quality of the treated wastewater. When the detection is unqualified, the circulation pump 8 is started. When the circulation pump 8 is turned on, the first switch valve 11 is in the closed state and the second switch valve 12 is in the open state. The circulation pump 8 can suck the wastewater after single treatment into the interior of the reflux pipe 7, and the wastewater flows into the interior of the treatment tank 301 through the reflux pipe 7. When the wastewater flows through the adsorption layer 303, the adsorption layer 303 can adsorb the harmful substances remaining in the wastewater. The wastewater after adsorption treatment flows back into the interior of the treatment barrel 1 through the circulation pump 8 and the reflux pipe 7 for cyclic re-treatment. The wastewater after cyclic treatment can flow into the drainage pipe 10 again. The water quality monitor set on the drainage pipe 10 detects the wastewater after cyclic treatment. If the detection is qualified, the first switch valve 11 is opened, and the qualified treated wastewater is introduced into the recovery water tank through the drainage pipe 10. If the detection is unqualified, the second switch valve 12 is opened for secondary cyclic treatment, thus realizing the cyclic treatment of the wastewater.
