Description

Technical Field

[0001] The invention relates to the technical field of grease separation, in particular to printing ink wastewater grease separation equipment. Background Art

[0002] As an important means of information dissemination, printing technology plays an indispensable role in modern society. It not only promotes the popularization of knowledge and the dissemination of culture, but also plays a key role in many fields such as education, business, and advertising. Through printing, we can present thoughts, creativity, and information in a visual form, which promotes the progress of human civilization and the development of society. Whether it is books, newspapers, or advertising materials, printing is constantly enriching our lives and connecting every corner of the world.

[0003] However, in the printing industry, wastewater often contains a large amount of grease, and effective separation of these greases is crucial to protecting the environment and public health. If grease is discharged directly without treatment, it will cause serious pollution to the water body and affect the balance of the aquatic ecosystem. In addition, grease may also clog drainage pipes and increase the maintenance cost of wastewater treatment facilities. By separating grease, we can not only reduce the negative impact on the environment, but also recycle grease resources and achieve sustainable development. Therefore, separating grease from wastewater is an important part of the green development of the printing industry.

[0004] In existing separation equipment, flotation is usually used to separate grease from wastewater. However, the floating speed of bubbles generated by existing equipment is fixed and cannot be adjusted, so it is impossible to ensure the combination of grease particles and bubbles at different stages of grease separation. For example, at the end of grease separation, the concentration of grease particles in wastewater decreases. At this time, if the floating speed of bubbles is fixed, the contact probability between bubbles and grease particles will decrease, thereby prolonging the overall grease separation process and reducing the separation efficiency.

[0023] 1. The present invention continuously moves the spiral blade upward by adjusting the component until the spiral blade is in contact with the inner wall of the shell. When the spiral blade is in contact with the inner wall of the shell, the bubbles generated by the air intake component can only rise in a spiral along the outer wall of the spiral blade, and the path in the floating process becomes longer, thereby increasing the floating time of the bubbles and increasing the probability of the bubbles contacting with grease in the floating process. In addition, the grease in the wastewater may adhere to the outer wall of the spiral blade, and the bubbles will gradually move upward along the outer wall of the spiral blade during the floating process, which can make the floating bubbles more effectively combine with the grease in the wastewater, thereby preventing the bubbles from floating too fast at the end of the separation process and failing to fully combine with the residual grease in the wastewater. This not only prevents the residual grease from forming a viscous film on the inner wall of the equipment, but also reduces the probability of pipeline blockage and equipment failure, reduces maintenance costs, and improves the efficiency of the entire process.

[0024] 2. The present invention drives a gear fixed on the outer wall of the air intake pipe through an external motor, so that the air intake pipe drives the piston body to rotate, and then the piston body drives the piston plate and the piston rod to rotate together. Since the eccentric circular groove and the piston body are eccentrically arranged, during the rotation of the piston body, the piston rod drives the piston plate to reciprocate in the piston body. During the movement of the piston body, one side of the air in the piston body is in a negative pressure state and the other side is in a high pressure state. The side in the negative pressure state will draw air from the outside through the air intake pipe, and the air on the side in the high pressure state will enter the inner wall of the outer shell through the conveying pipe, thereby achieving the purpose of generating bubbles, and then the bubbles combine with the grease in the wastewater and float up.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 9 The present invention provides a technical solution: a printing ink wastewater grease separation device, comprising a shell 1, the shell 1 is divided into three sections, the middle section is set to be conical, the bottom of the shell 1 is fixedly connected to a base 25, and the center of the shell 1 is provided with a spiral blade 2;

[0037] It also includes an adjustment component that can move the spiral blade 2 up and down, and the spiral blade 2 can be attached to or separated from the inner wall of the middle section of the shell 1 when moving up and down;

[0038] Also included is a collection assembly capable of collecting grease that floats above the wastewater liquid surface;

[0039] It also includes an air intake component that can generate bubbles from below the spiral blade 2.

[0040] When the device is in use, the spiral blade 2 is first moved downward by adjusting the component, thereby separating the spiral blade 2 from a middle section of the inner wall of the outer shell 1, and then the printing ink wastewater is introduced into the interior of the outer shell 1 from the water inlet of the outer wall of the outer shell 1, and air is introduced to the bottom of the spiral blade 2 through the air intake component, thereby generating bubbles. In the process of the bubbles floating above the liquid surface, they will combine with the grease and bring the grease to float together, thereby completing the process of accelerating the floating of the grease. When the grease floats above the liquid surface, the grease floating above is collected by the collecting component for subsequent treatment.

[0041] However, at the end of oil separation, the concentration of oil particles in the wastewater decreases. At this time, if the bubble floating speed is constant, the contact probability between the bubbles and the oil particles will decrease, thereby prolonging the overall oil separation process and reducing the separation efficiency. In addition, residual oil will affect the efficiency of subsequent treatment processes. For example, in the biological treatment process, oil will inhibit the growth and metabolism of microorganisms and reduce the treatment effect.

[0042] Therefore, during the entire separation process, the regulating component will continuously move the spiral blade 2 upward until the spiral blade 2 is in contact with the inner wall of the outer shell 1. When the spiral blade 2 is in contact with the inner wall of the outer shell 1, the bubbles generated by the air intake component can only rise in a spiral along the outer wall of the spiral blade 2, and the path during the floating process becomes longer, thereby increasing the time for the bubbles to float up, and increasing the probability of the bubbles contacting with grease during the floating process. In addition, the grease in the wastewater may adhere to the outer wall of the spiral blade 2, and the bubbles will gradually move upward along the outer wall of the spiral blade 2 during the floating process, which can enable the floating bubbles to more effectively combine with the grease in the wastewater, thereby preventing the bubbles from floating up too fast at the end of the separation process and being unable to fully combine with the residual grease in the wastewater. This not only prevents the residual grease from forming a viscous film on the inner wall of the equipment, but also reduces the probability of pipeline blockage and equipment failure, reduces maintenance costs, and improves the efficiency of the entire process.

[0043] It is worth mentioning that the cross section of the spiral blade 2 is trapezoidal, which prevents the bubbles from adhering to the outer wall of the spiral blade 2 and corroding the outer wall of the spiral blade 2 during the floating process.

[0044] Furthermore, the air intake assembly includes an eccentric circular groove 18 provided at the bottom of the outer shell 1, and also includes a piston body 15 rotatably installed at the inner bottom of the eccentric circular groove 18 through an air intake pipe 24, and the air intake pipe 24 is coaxially arranged with the outer shell 1, and a piston plate 16 is slidably installed on the inner wall of the piston body 15, and piston rods 17 are fixedly installed on the outer walls on both sides of the piston plate 16, and the two piston rods 17 both penetrate the outer wall of the piston body 15 and can fit with the inner arc surface of the eccentric circular groove 18, and a delivery pipe 19 that can only exhaust air in one direction is fixedly installed on the outer wall of the piston body 15, the air intake pipe 24 penetrates the bottom of the outer shell 1, and a one-way air intake valve is installed inside, and a gear is fixedly connected to the outer wall of the air intake pipe 24, and the gear is driven by an external motor.

[0045] See also Figure 2 as well as Figure 3 , an external motor drives a gear fixed on the outer wall of the air intake pipe 24, so that the air intake pipe 24 drives the piston body 15 to rotate, and then the piston body 15 drives the piston plate 16 and the piston rod 17 to rotate together. Since the eccentric circular groove 18 is eccentrically arranged with the piston body 15, during the rotation of the piston body 15, the piston rod 17 drives the piston plate 16 to reciprocate in the piston body 15. During the movement of the piston body 15, one side of the air in the piston body 15 is in a negative pressure state, and the other side is in a high pressure state. The side in the negative pressure state will absorb air from the outside through the air intake pipe 24, and the air on the side in the high pressure state will enter the inner wall of the outer shell 1 through the conveying pipe 19, thereby achieving the purpose of generating bubbles, and then the bubbles combine with the grease in the wastewater and float up.

[0046] Further, the adjustment assembly includes a rotating rod 6 fixedly connected to the top of the piston body 15, and the rotating rod 6 is coaxially arranged with the air intake pipe 24, the inner wall of the housing 1 is fixed with a fixed sleeve 5 through a bracket, the inner wall of the fixed sleeve 5 is vertically slidably mounted with a movable sleeve 7 through a flat key, the movable sleeve 7 is sleeved on the outer wall of the rotating rod 6, and can rotate and slide relative to the rotating rod 6, and the spiral blade 2 is fixedly connected to the outer wall of the movable sleeve 7;

[0047] The adjusting assembly also includes a lifting assembly that enables the movable sleeve 7 to slide up and down.

[0048] See also Figure 2The spiral blade 2 is fixedly connected to the outer wall of the movable sleeve 7, and the movable sleeve 7 is vertically slidably installed on the inner wall of the fixed sleeve 5 through a flat key, and the movable sleeve 7 and the rotating rod 6 can rotate and slide relative to each other. In the early stage of the grease separation process, the grease concentration in the wastewater is relatively high. The movable sleeve 7 is lowered by the lifting component, thereby driving the spiral blade 2 to move downward, so that the spiral blade 2 is separated from the inner wall of the middle section of the outer shell 1, and then the generated bubbles can float from both sides of the inner wall of the outer shell 1, maintaining a faster floating speed, so that the bubbles can more quickly combine with the grease in the wastewater and drive the grease to float together, thereby improving the separation efficiency in the early stage of separation.

[0049] In the later stage of oil separation, the oil concentration in the water continues to decrease. If the bubbles maintain their original floating speed, the probability of combining with the residual oil in the wastewater will be reduced, thereby increasing the time of the entire process. Therefore, in the separation process, the lifting assembly will drive the movable sleeve 7 to gradually rise until it fits with the inner wall of the outer shell 1. When the spiral blade 2 fits with the inner wall of the outer shell 1, the bubbles can only rise along the spiral path of the spiral blade 2, increasing the time taken for the bubbles to float up, so that the bubbles can combine with the residual oil with a greater probability and drive it to float up.

[0050] Furthermore, the lifting assembly includes a mounting plate 14 rotatably connected to the top of the piston body 15, an airbag 12 and a tension spring 13 are fixedly installed between the top of the mounting plate 14 and the bottom of the movable sleeve 7, a one-way air outlet 32 ​​is opened at the top of the piston body 15, a connecting channel 33 is opened inside the mounting plate 14, the lower end of the connecting channel 33 is set as an annular groove, and the air outlet 32 ​​is connected to the annular groove, the connecting channel 33 is connected to the inside of the airbag 12, an air outlet channel 29 connected to the airbag 12 is opened inside the movable sleeve 7, and a removable sealing plug is installed at the outlet of the air outlet channel 29.

[0051] See also Figure 2 as well as Figure 3 An airbag 12 and a tension spring 13 are installed between the movable sleeve 7 and the mounting plate 14. Before the grease separation begins, the staff manually opens the sealing plug at the outlet of the air outlet channel 29 to discharge the air in the airbag 12, and resets the movable sleeve 7 through the tension spring 13, thereby driving the spiral blade 2 to separate from the inner wall of the shell 1. After the air in the airbag 12 is exhausted, the sealing plug is installed at the outlet of the air outlet channel 29.

[0052] During the grease separation process, the piston plate 16 is constantly moving back and forth. Fig. 9The reciprocating movement of the piston plate 16 causes air to continuously enter the connecting channel 33 from the air outlet 32, and then enter the interior of the airbag 12 through the connecting channel 33, so that the airbag 12 continues to expand. During the expansion process, the movable sleeve 7 is driven to move upward until the spiral blade 2 fits against the inner wall of the outer shell 1, thereby achieving the purpose of controlling the lifting and lowering of the movable sleeve 7.

[0053] It is worth noting that the inner diameter of the air outlet 32 ​​is small, so that the airbag 12 can sufficiently complete the subsequent process of grease separation during the expansion time.

[0054] Furthermore, an annular buffer chamber 20 is fixedly connected to the outer wall of the delivery pipe 19, and the delivery pipe 19 is communicated with the inside of the annular buffer chamber 20. A connecting air pipe 21 is installed on the top of the annular buffer chamber 20, and an annular plate 22 is vertically slidably installed on the outer wall of the connecting air pipe 21. The connection between the annular plate 22 and the connecting air pipe 21 is an elastic block 26, and the elastic block 26 is provided with a deformable opening 27 for the connecting air pipe 21 to penetrate;

[0055] Also included is a moving assembly capable of moving the annular plate 22 up and down.

[0056] See also Figure 3 as well as Figure 6 In the initial stage of ink separation, the deformed opening 27 opens and covers the outer wall of the connecting air pipe 21, and the air in the piston body 15 enters the annular buffer chamber 20 through the delivery pipe 19, and then enters the housing 1 through the connecting air pipe 21. As the separation process proceeds, the moving assembly causes the annular plate 22 to gradually move upward. Figure 5 The deformed opening 27 is partially separated from the inside of the connecting air pipe 21. Under the elastic action of the elastic block 26, the deformed opening 27 is gathered together, so that the outlet of the connecting air pipe 21 becomes smaller, thereby making the bubbles going out of the connecting air pipe 21 smaller. The rising speed of small bubbles is reduced, and it is easier to combine with the grease in the wastewater. In addition, since the outlet diameter of the connecting air pipe 21 is reduced, the number of bubbles will increase, and the grease remaining in the wastewater can be captured more densely to achieve a further separation effect.

[0057] Furthermore, the moving assembly includes a rotating ring 36 rotatably mounted on the outer wall of the moving sleeve 7 , an annular fixing plate 28 is fixedly mounted on the inner ring of the annular plate 22 , and a fixed connecting rod 23 is fixedly connected between the outer wall of the rotating ring 36 and the top of the annular fixing plate 28 .

[0058] See also Figure 2In the process of the airbag 12 inflating and causing the movable sleeve 7 to rise, the movable sleeve 7 will drive the rotating ring 36 to move upward together, so that the rotating ring 36 drives the annular fixed plate 28 and the annular plate 22 to rise through the fixed connecting rod 23, so as to achieve the purpose of reducing the above-mentioned bubble. On the contrary, when the airbag 12 is deflated, the movable sleeve 7 is lowered and reset through the tension spring 13, and the lowering of the movable sleeve 7 will drive the annular plate 22 to lower, thereby completing the process of moving the annular plate 22 up and down, so that the deformation opening 27 can control the size of the bubble coming out of the connecting air pipe 21, thereby achieving the purpose of controlling the speed of the bubble floating up.

[0059] Furthermore, the collecting assembly includes two mounting seats 35 fixedly connected to the top of the housing 1, a conveying wheel 10 is rotatably mounted between the two mounting seats 35, a conveying belt 8 is mounted on the outer wall of the conveying wheel 10, an opening is provided at the top of the housing 1, and the conveying belt 8 extends into the interior of the housing 1 through the opening;

[0060] The collecting assembly further comprises an oil scraper plate 31 fixedly mounted on the top of the outer shell 1 , and one end of the oil scraper plate 31 is always in contact with the conveyor belt 8 . A guide groove 11 is arranged on the top of the outer shell 1 .

[0061] See also Figure 7 The conveyor belt 8 is made of oleophilic and hydrophobic material. The grease floating above the liquid surface will be absorbed by the conveyor belt 8. In the process of continuous rotation of the conveyor belt 8 driven by the conveyor wheel 10, the grease absorbed on the conveyor belt 8 will be scraped off by the scraper plate 31, and then flow into the guide groove 11, and a collection device is received at the notch of the guide groove 11, thereby achieving the purpose of separating and collecting the grease.

[0062] Furthermore, a stirring rod 9 is fixedly mounted on the outer wall of the rotating rod 6 located above the movable sleeve 7 .

[0063] See also Figure 7 When the rotating rod 6 rotates, the stirring rod 9 will be driven to rotate. The rotation of the stirring rod 9 will form a small vortex above the liquid surface, so that the surrounding grease will continue to move toward the center of the vortex, so that the conveyor belt 8 can better collect the grease gathered in the center, and can also effectively prevent the grease from adhering to the outer wall of the shell 1.

[0064] Furthermore, a ball 34 is installed between the rotating ring 36 and the movable sleeve 7 .

[0065] See also Figure 2 The rotating ring 36 and the outer wall of the movable sleeve 7 are rotatably connected through the ball bearings 34, which reduces the friction between the rotating ring 36 and the movable sleeve 7 and increases the service life of the equipment.

[0066] Furthermore, a circular groove 30 is formed on the outer wall of the spiral blade 2 , and a fixing rod 3 is fixedly connected to the top of the mounting plate 14 . The fixing rod 3 passes through the circular groove 30 , and a plugging piece 4 capable of sealing the circular groove 30 is fixedly connected to the outer wall of the fixing rod 3 .

[0067] See also Figure 2 The outer wall of the spiral blade 2 is provided with a circular groove 30, and the plugging piece 4 fixedly connected to the outer wall of the fixing rod 3 can seal the circular groove 30. In the initial stage of separation, due to the high density of grease in the wastewater, the bubbles need to rise quickly to combine with the grease in the water and accelerate the floating, so the movable sleeve 7 is at the lowest end, so that the spiral blade 2 moves downward and separates from the inner wall of the shell 1, and the circular groove 30 is separated from the plugging piece 4 during the downward movement. Figure 8 The rising bubbles can not only rise from the circular groove 30, but also rise from the gap between the inner wall of the shell 1 and the spiral blade 2, so as to increase the rising speed of the bubbles.

[0068] At the end of the separation, the rise of the movable sleeve 7 drives the spiral blade 2 to rise. The spiral blade 2 fits against the inner wall of the outer shell 1, and the circular groove 30 overlaps with the plugging piece 4, sealing the circular groove 30, so that the bubbles in the wastewater can only rise along the path of the spiral blade 2, extending the time and distance used for the rise, and can more fully combine with the residual grease in the wastewater and drive it to float above the liquid surface, so that the conveyor belt 8 can absorb the grease.

[0069] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0070] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
