Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a pollution-free separation and treatment device for waste printing ink. Background Art

[0002] Printing wastewater is generated during the printing process. The wastewater contains a large amount of metal ions, ink, alkali, engine oil, etc. The main components of printing wastewater include water-soluble organic matter, suspended matter, grease, heavy metals, etc. If these wastewaters are discharged directly into the environment without treatment, it will cause serious pollution and harm to water resources and the ecological environment. Therefore, when discharging or recycling printing wastewater, it is necessary to treat the internal impurities or harmful substances.

[0003] In the prior art, a large amount of foam exists on the liquid surface of ink wastewater when it is discharged. The presence of foam will adhere to impurities, etc., affecting the subsequent separation of impurities. The existing treatment of foam in wastewater mainly relies on directly adding defoaming agents into the wastewater. The defoaming agent has a long effective time. In the invention with publication number CN116715303A, the effect of removing foam is achieved by utilizing the activity of a push-up plate in conjunction with the flattening of a first elastic band. When the push-up plate rises in the wastewater, it will lift up the middle position of the wastewater, and then make the foam floating on the top of the wastewater move toward the outer circle. At this time, the first elastic band will be spread out to lift up the foam, and then make the foam break after it moves away from the water surface.

[0004] However, in the above patent, after the foam is away from the water surface, it still takes a period of time for the foam to burst, and the time required for large and small foams to burst is also different. In addition, in the above patent, when the first elastic band is spread out to lift up the foam, part of the wastewater will also be lifted up. The bubbles on the first elastic band are still in contact with the wastewater, which makes the bubble burst time longer, thereby reducing the overall ink wastewater treatment efficiency.

[0020] First: through the bubble-chasing mechanism, the foam on the water surface is blown to the upper end of the slope, so that the foam can be far away from the water surface.

In addition, since the diameters of gears 4 and 3 are smaller than those of gear 2, the fan blades and the friction block rotate more times, so that the jet hole of the rotating spray rod jets faster and more heat is generated on the heat-conducting ring.

[0022] Thirdly, the baffle plate is pulled toward the rotating block 1 by the strong spring, and the slide groove where the baffle plate is located is connected with the collecting chamber, so that the space outside the foam suddenly becomes larger, and the pressure around the foam suddenly decreases, so that the pressure inside the foam is greater than the pressure outside the foam, and further the foam is basically completely expanded and ruptured;

[0023] To sum up, through the cooperation of the bubble chasing mechanism and the heating mechanism, the rotating spray rod can make the foam away from the wastewater and burst faster. At the same time, the rotating spray rod can also conduct the heat generated on the heat conductive ring to the bottom of the collecting block through the heat conductive wire, so that the foam located at the upper end of the slope can expand due to the heat, thereby further accelerating the expansion and bursting speed of the foam. When the rotating spray rod continues to rotate, the baffle shrinks into the rotating block under the pull of the strong spring, and the slide groove where the baffle is located is connected with the collecting chamber, so that the space outside the foam suddenly becomes larger, and the pressure around the foam suddenly decreases, so that the pressure inside the foam is greater than the pressure outside the foam, thereby further making the foam basically completely expanded and burst.

[0044] Specifically, through the cooperation of the bubble chasing mechanism 7 and the heating mechanism 14, the rotating spray rod 75 is rotated so that the foam can be broken faster after being away from the wastewater. While the rotating spray rod 75 is rotating, the heat generated on the heat conductive ring 141 can be transmitted to the bottom of the collecting block 81 through the heat conductive wire 144, so that the foam located at the upper end of the slope 8101 can expand due to the heat, thereby further accelerating the expansion and bursting speed of the foam. When the rotating spray rod 75 continues to rotate, the baffle 85 is pulled into the rotating block 71 by the strong spring 813, and the slide groove where the baffle 85 is located is connected to the collecting chamber 8102, so that the space outside the foam suddenly becomes larger, and the pressure around the foam suddenly decreases, so that the pressure inside the foam is greater than the pressure outside the foam, thereby further causing the foam to expand and burst.

[0045] In another embodiment provided by the present invention, the bubble-chasing mechanism 7 includes a rotating block 71 fixedly connected to the extended end of the air pump 6, and the rotating block 71 is located at the upper end of the inner cavity of the processing barrel 1, the rotating block 71 is close to the outer wall of the fixed column 4 and the inner wall of the processing barrel 1, one side of the rotating block 71 is located in the inner cavity of the processing barrel 1 and is provided with a rotating block 2 72, and the rotating block 2 72 is slidably arranged on the outer wall of the fixed column 4 up and down, and the other end of the rotating block 2 72 is close to the inner wall of the processing barrel 1, a fixing ring 13 is fixedly connected to the rotating block 2 72, and the fixing ring 13 is movably inserted in the rotating block 1 71, an arc-shaped pressing block 73 is fixedly connected to the inner wall of the upper end of the processing barrel 1, and the arc-shaped pressing block 73 is arranged close to the rotating block 2 72, and a straight tooth rod 74 is horizontally movably inserted at one end of the upper end of the rotating block 71 close to the processing barrel 1, and the straight tooth rod 74 is located at the rotating block A gear 78 is meshedly connected to the bottom side of one end of the block 71, a swivel 79 is rotatably provided on the side of the gear 78 close to the fixed column 4, and a transmission belt 710 is connected between the central axes of the swivel 79 and the gear 78, a rotating spray rod 75 is fixedly connected to one end of the swivel 79, and the rotating spray rod 75 extends to the outside of the rotating block 71, and the other end of the swivel 79 is fixedly connected to a gear 2 711 rotatably provided in the rotating block 1 71, a gear 3 712 is meshedly connected to the lower side of the gear 2 711, and a fan blade 713 is fixedly connected to the end of the gear 3 712 away from the rotating spray rod 75, an air suction hole 76 is provided on the side wall of the rotating block 1 71 away from the rotating spray rod 75, and the fan blade 713 is located in the air suction hole 76, and a hose 77 is connected between the inner cavity of the air suction hole 76 and the inner cavity of the rotating spray rod 75.

[0046] When the rotating block 1 71 is in the initial state, the side wall of the rotating block 1 71 opposite to the rotating spray rod 75 is tightly pressed against the rotating block 2 72 , and in the initial state, the air injection holes on the rotating spray rod 75 are obliquely upward toward the outer wall of the fixed column 4 .

[0047] Specifically, the foam on the water surface is blown to the upper end of the slope 8101 so that the foam can be away from the water surface. By blowing air, the waste water brought by the foam itself when the foam is separated from the waste water can be reduced as much as possible, so that the foam can burst faster after being away from the waste water.

[0048] In another embodiment provided by the present invention, the heating mechanism 14 includes a gear four 143 meshingly connected to one side of the gear two 711, a friction block 142 is fixedly connected to one end of the gear four 143, a heat conductive ring 141 is fixedly connected to one side of the friction block 142 located in the rotating block one 71, a collecting block 81 is fixedly connected to a side wall of the rotating block one 71 close to the rotating spray rod 75, a heat conductive wire 144 is connected between the bottom ends of the heat conductive ring 141 and the collecting block 81, and the gear four 143 and the gear three 712 are both smaller in diameter than the gear two 711.

[0049] Specifically, the heat generated on the heat-conducting ring 141 is conducted to the bottom end of the collecting block 81 through the heat-conducting wire 144, so that the foam located at the upper end of the slope 8101 can expand due to the heat, thereby further accelerating the expansion and rupture speed of the foam, and because the diameters of gear four 143 and gear three 712 are smaller than those of gear two 711, the fan blades 713 and the friction block 142 rotate more circles, so that the jet hole of the rotating spray rod 75 jets out faster, and more heat is generated on the heat-conducting ring 141.

[0050] In another embodiment provided by the present invention, the crushing mechanism 8 includes a collecting block 81, the collecting block 81 is fixed to the bottom end of the rotating block 1 71, one end of the collecting block 81 is in close contact with the inner wall of the processing barrel 1, the other end of the collecting block 81 is provided with a collecting chamber 8102, the lower part of the collecting chamber 8102 is provided with a slope 8101, the bottom end of the side wall of the rotating block 2 72 close to the arc-shaped pressing block 73 is movably inserted with a sliding frame 82, and one end of the sliding frame 82 is in close contact with the inner wall of the processing barrel 1, and the sliding frame 82 A spring 83 is fixedly connected between the lower side wall and the rotating block 2 72, an insert block 84 is movably sleeved in the sliding frame 82, and the insert block 84 is fixed to the rotating block 2 72, a protrusion 812 is fixedly connected to the outer wall of the fixed ring 13, and one end of the protrusion 812 is tightly attached to the side wall of the insert block 84 close to the arc-shaped pressure block 73, a ring block 86 is movably inserted on the side wall of the rotating block 1 71 close to the collecting block 81, and the ring block 86 is movably sleeved on the outer wall of the fixed ring 13, and the outer wall of one side of the ring block 86 is A slide plate 814 is fixedly connected and slidably arranged in the rotating block 71. A spring 87 is fixedly connected between the end of the slide plate 814 away from the protrusion 812 and the rotating block 71. A baffle 85 is provided on the other side of the slide plate 814, and the baffle 85 is movably inserted on the side wall of the rotating block 71. The baffle 85 is located in the collecting chamber 8102. A strong spring 813 is fixedly connected between the baffle 85 and the slide plate 814. A side wall of the baffle 85 close to the slide plate 814 abuts against the limit rod 88, and the limit rod 88 is fixedly connected to the slide plate 814. The positioning rod 88 is slidably set in the rotating block 71, and a spring 89 is fixedly connected between the upper side wall of the limiting rod 88 and the rotating block 71. A winding roller 810 is rotatably set on one side of the rotating spray rod 75 in the rotating block 71, and a torsion spring 815 is connected between the rotating block 71 and the center of one end of the winding roller 810. A pull rope is wound around the winding roller 810, and the other end of the pull rope is fixedly connected to the limiting rod 88. A shift rod 811 is fixedly connected to the outer wall of the connecting shaft between the rotating spray rod 75 and the swivel 79.

[0051] The insert block 84 can completely fill the collection chamber 8102, and the bottom end of the collection block 81 is a heat conducting part.

[0052] When the collecting block 81 is completely inserted into the second rotating block 72 , the limiting rod 88 will be separated from the baffle 85 .

[0053] Specifically, the baffle 85 contracts toward the rotating block 71 under the pull of the strong spring 813, and the slide groove where the baffle 85 is located is connected with the collecting chamber 8102, so that the space outside the foam suddenly becomes larger, and the pressure around the foam suddenly decreases, so that the pressure inside the foam is greater than the pressure outside the foam, which further causes the foam to expand and burst.

[0054] Working principle: When using the device, firstly, let the ink wastewater pass through the liquid inlet pipe 11 into the inner cavity of the treatment barrel 1, so that the water level of the wastewater is slightly higher than the lowest point of the slope 8101, and then discharge the external water into the treatment barrel 1 through the air blowing pipe 12 to dilute the wastewater. At the same time, the nozzle on the air blowing pipe 12 can spray off the foam attached to the lower surface of the rotating block 1 71, the rotating block 2 72 and the collecting block 81, so that these foams are on the water surface, and then start the motor 3 to make the rotating block 1 71 rotate from one side of the rotating block 2 72 to the other side opposite to the rotating block 2 72. During the rotation, the rotating block 1 71 concentrates all the foam on the water surface between the rotating block 1 71 and the rotating block 2 72. Then, when the straight gear rod 74 is squeezed by the arc-shaped pressing block 73, the straight gear rod 74 moves inward. Movement, through the transmission of the spur gear 74, gear one 78, transmission belt 710, swivel 79 and rotating spray rod 75, the rotating spray rod 75 is rotated, so that the air jet hole on the rotating spray rod 75 is rotated from the water surface close to the fixed column 4 to the water surface close to the collecting block 81, and the rotating spray rod 75 is rotated downward, and through the transmission of the swivel 79, gear two 711, gear three 712 and fan blade 713, the fan blade 713 is rotated, so that the fan blade 713 introduces wind into the rotating spray rod 75 and blows it out from the air jet hole, and finally the foam on the water surface is blown to the upper end of the slope 8101, so that the foam can be far away from the water surface. By blowing air, the wastewater brought by the foam itself when the foam is separated from the wastewater can be reduced as much as possible, so that the foam can be broken faster after being away from the wastewater;

[0055] When the gear 2 711 rotates, the gear 2 711 drives the gear 4 143 and the friction block 142 to rotate, so that the friction block 142 can rub against the heat-conducting ring 141, so that the heat generated on the heat-conducting ring 141 is transmitted to the bottom of the collecting block 81 through the heat-conducting wire 144, so that the foam located at the upper end of the slope 8101 can expand due to the heat, thereby further accelerating the expansion and rupture speed of the foam, and because the gear 4 143 and the gear 3 712 are smaller in diameter than the gear 2 711, the fan blade 713 and the friction block 142 rotate more times, so that the jet speed of the jet hole of the rotating spray rod 75 is faster, and more heat is generated on the heat-conducting ring 141;

[0056] When the rotating block 1 71 is closer to the rotating block 2 72, the rotating spray rod 75 will also be inserted into the rotating block 2 72 without affecting the rotation of the rotating spray rod 75. Then the collecting block 81 presses the sliding frame 82 into the rotating block 2 72, and the insert block 84 is inserted into the collecting cavity 8102 in the collecting block 81, and the outer wall of the insert block 84 is in close contact with the collecting block 81, so that the insert block 84 reduces the space in the collecting cavity 8102, which is more conducive to the subsequent change of the pressure difference in the collecting cavity 8102. When the collecting block 81 is fully inserted into the rotating block 2 72, the protrusion 812 has pressed the slide plate 814 into the rotating block 1 71. Since the collecting block 81 is in close contact with the rotating block 2 72, the collecting cavity 8102 is in a closed state. Due to the rotation of the rotating spray rod 75, the lever 811 squeezes the winding roller 810 downward, so that the winding roller 810 winds the draw rope thereon, so that the draw rope pulls the limit rod 88 toward the side away from the slide plate 814, so that the limit rod 88 is separated from the baffle 85, so that the baffle 85 is pulled into the rotating block 71 under the pull of the strong spring 813, and the slide groove where the baffle 85 is located is connected with the collecting chamber 8102, so that the space outside the foam suddenly becomes larger, and the pressure around the foam suddenly decreases, so that the pressure inside the foam is greater than the pressure outside the foam, and further causes the foam to expand and burst;

[0057] Finally, the upper layer of grease and the lower layer of ink are discharged into the reaction barrel 2 10 and the reaction barrel 1 9 respectively for subsequent multi-stage treatment.
