Description

Technical Field

[0001] This invention relates to the field of wastewater and waste liquid treatment devices, and in particular to a wastewater and waste liquid treatment device for the production of tobacco flavorings and fragrances. Background Technology

[0002] As the core raw material for cigarette production, the production process of tobacco flavorings and fragrances involves complex chemical reactions and material mixing processes. This process generates a large amount of high-concentration industrial wastewater. This wastewater has an extremely complex composition, containing not only unreacted raw materials, intermediate products, and finished product residues, but also emulsified oils, suspended particulate matter, and colloidal substances introduced during production. This forms a stable emulsion system, resulting in extremely high chemical oxygen demand (COD) and biochemical oxygen demand (BOD) values ​​for the wastewater. Furthermore, the water quality fluctuates greatly, making treatment extremely difficult. Wastewater treatment equipment is required to treat the generated wastewater to meet standards before it can be discharged.

[0003] However, existing wastewater and waste liquid treatment devices are not very effective at demulsifying wastewater. Traditional demulsification methods rely heavily on the addition of chemical agents, which not only consumes a lot of agents and has high treatment costs, but may also introduce new pollutants. Furthermore, it is difficult to completely destroy the stable emulsion system of wastewater, resulting in incomplete separation of oil, water and suspended impurities, and low efficiency of subsequent solid-liquid and liquid-liquid separation.

A circular rod is fixedly disposed on one side of the rectangular plate, and one end of the circular rod movably passes through the annular plate and extends into the annular groove.

[0020] An arc-shaped groove is provided inside the base corresponding to the end of the rectangular cavity, and an unlocking component is assembled inside the arc-shaped groove.

It also facilitates the uniform mixing of flocculant and wastewater, improving the efficiency of wastewater purification. At the same time, the scraper in the aeration mechanism can push the sludge at the bottom of the filter cylinder into the sludge outlet, making it easier to clean the sludge.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figure 1 - Figure 13The present invention provides a technical solution:

[0045] A wastewater and waste liquid treatment device for tobacco flavoring and fragrance production includes a filter cylinder 1. Three support legs are bolted to the bottom of the filter cylinder 1, evenly distributed circumferentially along the bottom end face of the filter cylinder 1 for support. A water inlet 2 is located at the top of the filter cylinder 1, above a filter screen cylinder 16, to facilitate precise injection of wastewater into the filter screen cylinder 16. A chemical dosing port 4 is located on the side wall of the filter cylinder 1, below a water guide plate 18, for adding flocculant into the filter cylinder 1. An outlet 5 is located on the outer bottom wall of the filter cylinder 1 for the purified water to flow out, and a sludge outlet 22 is located on the bottom surface of the filter cylinder 1 for discharging sludge generated during the treatment process. The top surface of the filter cylinder 1 also has an inspection port equipped with an openable sealing end cap, allowing for cleaning and maintenance of impurities trapped inside the filter screen cylinder 16 by opening the sealing end cap. The device also includes:

[0046] The connecting shaft 15 is rotatably inserted inside the filter cylinder 1. The top end of the connecting shaft 15 is connected to the drive motor 3, and the drive motor 3 is fixedly installed on the top end face of the filter cylinder 1, providing a power source for the overall operation of the device.

[0047] The guide plate 18 is funnel-shaped, with its larger diameter end facing upwards and its smaller diameter end facing downwards. It guides the pretreated wastewater precisely to the guide impeller 11 and impeller 2 14 below, facilitating demulsification, improving wastewater purification, enhancing process continuity, and providing stable water flow conditions for subsequent demulsification treatment. The guide plate 18 is fixedly connected to the inner wall of the filter cylinder 1. Above the guide plate 18 is a pretreatment mechanism for pre-treating the wastewater. This pretreatment mechanism facilitates the removal of suspended particles, floating matter, and other impurities from the wastewater, preventing clogging and wear of subsequent treatment equipment. Extending the equipment's service life is beneficial for wastewater treatment; it also reduces the concentration of pollutants in the wastewater, lessens the load on subsequent core treatment units such as demulsification and aeration, and improves overall treatment efficiency; it is equipped with a demulsification mechanism below for demulsifying the wastewater. The use of the demulsification mechanism facilitates the disruption of the wastewater emulsion system, separating and stratifying the originally stable mixture of oil, water, and suspended impurities, which is conducive to subsequent solid-liquid and liquid-liquid separation and wastewater treatment; at the same time, it can also remove difficult-to-treat pollutants such as emulsified organic matter and grease, reduce pollution indicators such as COD and BOD in wastewater, and improve water purification effect.

[0048] The aeration mechanism is mounted at the bottom of the connecting shaft 15 and works in conjunction with the demulsification mechanism to enhance the separation of pollutants and the mixing of reagents. Specifically, the use of the aeration mechanism facilitates the generation of bubbles, which can enhance the separation of wastewater from impurities after demulsification and help improve the efficiency of solid-liquid separation. It also facilitates the uniform mixing of flocculant and wastewater, thereby improving the efficiency of wastewater purification.

[0049] The short shaft 24 is coaxially fixed to the bottom of the connecting shaft 15 and passes through the bottom of the filter cylinder 1. The outer wall of the short shaft 24 is provided with a sealing mechanism for sealing the mud outlet 22. A circular limiting plate 10 is fixed to the bottom of the short shaft 24 to limit the downward stroke of the sealing mechanism and prevent the parts from falling off. By using the sealing mechanism, it is easy to seal the mud outlet 22 and prevent wastewater from leaking out of the mud outlet 22, thereby facilitating the purification of wastewater.

[0050] In this invention, the demulsification mechanism includes impeller 11 and impeller 2 14 spaced apart and sleeved on the outer wall of the connecting shaft 15. Impeller 11 and impeller 2 14 are both static shell structures. Several fixing rods 12 are uniformly fixed along the circumference of the outer wall of their shells. The other end of the fixing rods 12 is welded and fixed to the inner wall of the filter cylinder 1, so as to realize the fixed installation of impeller 11 and impeller 2 14 in the filter cylinder 1. When impeller 11 and impeller 2 14 rotate, they generate mechanical shearing force. When the wastewater comes into contact with impeller 11 and impeller 2 14, it will destroy the stable interface film on the surface of the emulsion droplets, so that the oil droplets are released from the emulsion state and aggregate. At the same time, the spaced arrangement of impeller 11 and impeller 2 14 forms a multi-stage shearing action, thereby efficiently destroying the emulsion system of wastewater and realizing the stratification of oil, water and suspended impurities.

[0051] Among them, impeller 214 generates downward airflow when rotating, which is used for aeration of wastewater.

[0052] In this invention, the aeration mechanism includes a connector 21 rotatably sleeved on the bottom outer wall of the connecting shaft 15. The connector 21 has an annular hollow structure. The connector 21 and the impeller 14 are fixedly connected through an air guide funnel 13, which has a funnel-shaped structure that is larger at the top and smaller at the bottom. The air guide funnel 13 is fixedly connected to the bottom of the shell of the impeller 14, so that the air generated by the impeller 14 can enter the connector 21. A plurality of scrapers 19 are evenly fixed on the outer wall of the connector 21. A strip cavity 20 is opened inside the scraper 19. A plurality of air blowing holes 23 communicating with the outside are evenly opened on the top surface of the strip cavity 20. The air generated by impeller 14 enters the connector 21 through the air guide funnel 13, and then is distributed to the strip cavity 20 of each scraper 19. Finally, it is sprayed out from the air blowing hole 23 to form microbubbles. At the same time, the connecting shaft 15 drives the scraper 19 to rotate, realizing aeration and stirring. When the connecting shaft 15 rotates, it drives the scraper 19 to rotate, which facilitates the comprehensive aeration of the wastewater inside the filter cylinder 1, thereby facilitating the full mixing of flocculant and wastewater and improving the efficiency of wastewater treatment. At the same time, when the scraper 19 rotates, it pushes the mud on the bottom surface of the filter cylinder 1 into the mud outlet 22, which facilitates mud cleaning and improves the efficiency of mud cleaning.

[0053] In this invention, the sealing mechanism includes an annular plate 25 slidably sleeved on the outer wall of the short shaft 24. One end of the annular plate 25 is fixedly connected to a base 8. A sealing plate 7 adapted to the mud outlet 22 is fixedly installed on the base 8. The size of the sealing plate 7 is adapted to the size of the mud outlet 22 and is used to seal or open the mud outlet 22.

[0054] The short shaft 24 is equipped with a lifting component for lifting the annular plate 25. The use of the lifting component facilitates the lifting of the sealing plate 7, thereby facilitating the opening or closing of the mud outlet 22.

[0055] The base 8 has a rectangular cavity 32 inside, and a snap-fit ​​assembly is installed inside the rectangular cavity 32. The snap-fit ​​assembly facilitates the control of the lifting or idling of the annular plate 25.

[0056] In this invention, the lifting component includes a spiral groove 27 formed on the outer wall of the short shaft 24 and an annular groove 35 formed on the top of the spiral groove 27. The annular groove 35 is connected to the spiral groove 27. A positioning component is provided at the junction of the annular groove 35 and the spiral groove 27. The positioning component facilitates the limiting of the circular rod 36, ensuring that the circular rod 36 will not enter the spiral groove 27 when the annular groove 35 rotates clockwise, while the circular rod 36 can enter the spiral groove 27 when the annular groove 35 rotates counterclockwise.

[0057] In this invention, the positioning component includes a limiting groove provided at the junction of the annular groove 35 and the spiral groove 27, which prevents the guide plate 37 from rotating counterclockwise. A torsion spring shaft 38 is rotatably provided in the limiting groove, and a guide plate 37 is provided on the torsion spring shaft 38. Under the elastic action of the torsion spring of the torsion spring shaft 38, the guide plate 37 always maintains the state of blocking the entrance of the spiral groove 27, thereby realizing the positioning and guiding function.

[0058] In this invention, the snap-fit ​​assembly includes a rectangular plate 28 slidably disposed in a rectangular cavity 32 and a rectangular limiting plate 26 fixedly disposed in a rectangular cavity 32. A spring 23 is provided between the rectangular limiting plate 26 and the rectangular plate 28. A circular rod 36 is fixedly disposed on one side of the rectangular plate 28, and one end of the circular rod 36 movably passes through the annular plate 25 and extends into the annular groove 35.

[0059] An arc-shaped groove 31 is provided inside the base 8 corresponding to the end of the rectangular cavity 32, and an unlocking component is assembled inside the arc-shaped groove 31.

[0060] In this invention, the unlocking component includes an arc-shaped rod 29 slidably disposed within the arc-shaped groove 31 and a spring 30 disposed between the arc-shaped groove 31 and the arc-shaped rod 29. The rectangular plate 28 and the arc-shaped rod 29 are connected by a traction rope 34. Pressing the arc-shaped rod 29 can pull the rectangular plate 28 through the traction rope 34 to compress the spring 33, causing the circular rod 36 to disengage from the spiral groove 27, thus enabling the short shaft 24 to rotate freely. After release, the spring 30 drives the arc-shaped rod 29 to reset, and the spring 33 pushes the rectangular plate 28 to reset.

[0061] The bottom surface of the filter cylinder 1 is also fixed with baffle 6 and baffle 9 for limiting the movement of the base 8. Baffle 6 and baffle 9 are radially distributed along the short axis 24. Baffle 9 is located at the edge of the mud outlet 22 and is used to limit the sealing limit position of the sealing plate 7. Baffle 6 is used to limit the opening limit position of the sealing plate 7 to ensure sealing accuracy.

[0062] In this invention, the pretreatment mechanism includes an annular support plate 17 fixedly connected to the inner wall of the filter cylinder 1. A filter screen cylinder 16 is rotatably supported on the top surface of the annular support plate 17, and the filter screen cylinder 16 is coaxially fixedly connected to the connecting shaft 15. When the connecting shaft 15 rotates, it drives the filter screen cylinder 16 to rotate synchronously, thereby achieving efficient filtration of wastewater by using centrifugal force to remove impurities such as suspended particles and floating matter.

[0063] Working principle: First, wastewater is injected into the filter cylinder 16 through the inlet 2. Then, the drive motor 3 is started, causing the output shaft of the drive motor 3 to rotate clockwise. The drive motor 3 drives the connecting shaft 15 to rotate at a constant speed around its own axis. Then, the connecting shaft 15 synchronously drives the filter cylinder 16 to rotate. Under the action of centrifugal force, the wastewater flows out through the filter holes of the filter cylinder 16. The suspended particles, floating objects and other impurities in the wastewater are trapped in the filter cylinder 16, realizing the pretreatment of wastewater. The pretreated wastewater falls into the funnel-shaped guide plate 18 below. Under the guidance of the guide plate 18, it flows precisely to the impeller 11 and impeller 2 14.

[0064] As the connecting shaft 15 rotates, it drives the impeller 11 and impeller 2 14 to rotate, forming a shearing force. When the wastewater is subjected to multi-stage shearing action by the impeller 11 and impeller 2 14, the emulsion system is destroyed, and the oil, water and suspended impurities gradually separate into layers, thus achieving demulsification of the wastewater.

[0065] Meanwhile, when the impeller 14 rotates, it generates airflow. The airflow then enters the connector 21 through the air guide funnel 13, and is then distributed to the strip cavity 20 inside each scraper 19. Finally, it is evenly sprayed out from the air blowing hole 23 on the top surface of the strip cavity 20, forming tiny bubbles. Flocculant is added into the device through the dosing port 4. The flocculant and wastewater are fully mixed under the action of aeration and stirring, further improving the solid-liquid separation effect.

[0066] When the output shaft of the drive motor 3 rotates clockwise, the circular rod 36 rotates in the annular groove 35. When the circular rod 36 contacts the guide plate 37, the guide plate 37 will block the spiral groove 27, so that the circular rod 36 will not enter the spiral groove 27, thereby making the circular rod 36 continue to rotate in the annular groove 35, so that the annular plate 25 will not move.

[0067] After mixing is complete, the motor is stopped, allowing the sediment in the wastewater to settle and form sludge. Then, the purified water is discharged through the outlet 5 on the bottom outer wall of the filter cylinder 1, completing the wastewater purification process.

[0068] When it is necessary to discharge the mud from the filter cartridge 1, the output shaft of the drive motor 3 rotates counterclockwise, causing the connecting shaft 15 and the short shaft 24 to rotate counterclockwise. When the circular rod 36 contacts the guide plate 37, the circular rod 36 will be restricted, and then the circular rod 36 will enter the spiral groove 27. As the short shaft 24 rotates, the annular plate 25 will move downward, thereby driving the base 8 to move downward, which in turn drives the sealing plate 7 to move downward. When the sealing plate 7 disengages from the mud outlet 22, the circular rod 36 moves to the bottom of the spiral groove 27. Since the circular rod 36 is still inserted in the spiral groove 27, the annular plate 25 continues to rotate with the short shaft 24, realizing the rotation of the base 8 and the sealing plate 7, so that the mud outlet 22 is fully opened.

[0069] As the base 8 rotates, the arc rod 29 rotates. When the arc rod 29 contacts the baffle 6, it moves, which in turn moves the traction rope 34, causing the rectangular plate 28 to move. This further moves the circular rod 36, causing it to separate from the spiral groove 27. After the circular rod 36 separates from the spiral groove 27, the short shaft 24 spins freely. While the short shaft 24 is spinning freely, the connecting shaft 15 drives the scraper 19 to continue rotating, which facilitates pushing the mud on the bottom surface of the filter cylinder 1 into the mud outlet 22, thus improving the efficiency of mud cleaning.

[0070] When it is necessary to block the mud outlet 22, the output shaft of the control drive motor 3 rotates clockwise. Under the action of the second spring 33, the circular rod 36 is inserted into the spiral groove 27, and the annular plate 25 is not limited. Therefore, the base 8 will rotate with the short shaft 24, causing the base 8 and the blocking plate 7 to rotate and contact the second baffle 9. At this time, the base 8 and the blocking plate 7 are limited. Then, under the action of the spiral groove 27 and the circular rod 36, the blocking plate 7 moves upward. Finally, the blocking plate 7 blocks the mud outlet 22. At this time, the circular rod 36 moves into the annular groove 35, and the short shaft 24 spins freely.

[0071] The above description of the embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
