Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a tobacco wastewater treatment device based on magnetic seed flocculation technology. Background Technology

[0002] Currently, with the development of tobacco processing technology, the papermaking method for producing tobacco sheets has become the main technology for tobacco processing due to its advantages such as high utilization rate, low tar content, and good physicochemical properties. However, the papermaking process for producing tobacco sheets generates a large amount of wastewater. Calculations show that, under normal circumstances, the amount of wastewater generated per ton of tobacco sheet produced is 50-70 cubic meters. 3 The wastewater contains a wide variety of pollutants, many of which are highly toxic microorganisms, posing a potential threat to the ecological environment and human health. Therefore, combined processes must be employed to degrade different pollutants during treatment. This wastewater commonly contains high concentrations of suspended solids, exhibiting significant eutrophication characteristics, namely extremely high chemical oxygen demand (COD) and biological oxygen demand (BOD). Suspended solids include poorly soluble organic matter and ammonia-containing substances, and typically require magnetic adsorption for treatment.

[0003] In existing technologies, the method for treating suspended solids in wastewater usually involves adding magnetic seeds to the wastewater. The suspended solids are adsorbed onto the magnetic seeds and form flocs. The flocs then undergo several other wastewater treatment processes along with the wastewater. Finally, the flocs are removed and the magnetic seeds are separated.

[0004] Existing wastewater treatment devices subject flocculants to multiple wastewater treatment processes along with the wastewater. Even after the magnetic seeds have adsorbed enough suspended solids, multiple subsequent processes are still carried out, resulting in waste of the magnetic seeds and occupying processing space in subsequent processes. Consequently, the recycling efficiency is low and the processing flow is energy-intensive. Utility Model Content

A connecting pipe is disposed at the bottom of the collection chute, and the connecting pipe is connected to the input end of the deflocculator.

[0010] Optionally, a protective cover is provided on one side of the support disk where the permanent magnet column is located.

[0015] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following: This utility model provides a tobacco wastewater treatment device based on magnetic seed flocculation technology. Wastewater is introduced into the treatment chamber through the wastewater inlet, and magnetic seeds are added into the treatment chamber through the magnetic seed inlet. A magnetic seed pump circulates the magnetic seeds within the treatment chamber, allowing them to fully contact the suspended solids in the wastewater and form flocs. The flocs are then transported from the treatment chamber to a deflocculator via an extraction and transport mechanism, where they are decomposed into magnetic seeds and suspended solids. The wastewater treated with the magnetic seeds flows out through the wastewater outlet to continue other wastewater treatment processes. This structure allows for the introduction of magnetic seeds into the wastewater to adsorb suspended solids, and enables the timely removal of flocs for decomposition into magnetic seeds and suspended solids in the deflocculator. This shortens the residence time of the magnetic seeds in the wastewater treatment process, allowing for timely separation and reuse. Furthermore, by extracting the flocs from the wastewater in advance, energy consumption in subsequent wastewater treatment processes is reduced, effectively solving the problems of low reuse efficiency and high energy consumption in wastewater treatment processes caused by delayed magnetic seed recovery in existing technologies.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

Figures 1 to 9 The tobacco wastewater treatment device based on magnetic seed flocculation technology shown includes: a treatment chamber 1, a magnetic seed dispensing pump 2, an extraction and transport mechanism 3, and a deflocculator 4. The magnetic seed dispensing pump 2 is located on one side of the treatment chamber 1 and is connected to the treatment chamber 1. The treatment chamber 1 is provided with a magnetic seed dispensing port 11, a wastewater inlet 12, and a wastewater outlet 13. The input end of the extraction and transport mechanism 3 is connected to the treatment chamber 1, and the output end is connected to the deflocculator 4, which is used to extract the flocs from the treatment chamber 1 and transport them to the deflocculator 4.

[0021] In an exemplary embodiment of this utility model, the wastewater inlet 12 is located above the treatment chamber 1. Wastewater to be treated is introduced into the treatment chamber 1 through the wastewater inlet 12 via an external pipe. Magnetic seeds are introduced into the treatment chamber 1 through the magnetic seed inlet 11. The magnetic seed inlet pump 2 includes a first motor 21, an impeller 22, and a retaining ring 23. The first motor 21 drives the impeller 22 to rotate. The retaining ring 23 abuts against and limits the outer wall of the treatment chamber 1. The impeller 22 is inserted into the treatment chamber 1 to provide driving force for the magnetic seeds introduced into the treatment chamber 1, so that the magnetic seeds are fully mixed with the suspended matter in the treatment chamber 1 to form flocs. A flow monitoring module 24 is also provided on the magnetic seed inlet pump 2 to monitor and adjust the flow rate of magnetic seed introduction. The wastewater outlet 13 is located at the bottom of the treatment chamber 1 to facilitate the discharge of wastewater treated by magnetic seeds. The extraction and transportation mechanism 3 can be configured in various forms, such as a net, to scoop out the flocs in the treatment chamber 1 and transport them to the input end of the deflocculator 4. Inside the deflocculator 4, the agitation breaks down the flocs. The special flow channel design and high-speed rotating machinery of the deflocculator 4 generate strong shearing force, freeing the magnetic seeds within the flocs and facilitating their subsequent recovery. Compared to traditional technologies where the flocs undergo the entire wastewater treatment process before the magnetic seeds are recovered, the device in this embodiment removes the magnetic seeds immediately after use, enabling rapid recovery and recycling, thus improving recycling efficiency. Because the flocs are removed from the wastewater beforehand, the energy consumption for transporting and processing the flocs is eliminated in subsequent wastewater treatment processes, thereby reducing the overall energy consumption of the wastewater treatment process.

[0022] This utility model provides a tobacco wastewater treatment device based on magnetic seed flocculation technology. Wastewater is introduced into the treatment chamber 1 through the wastewater inlet 12, and magnetic seeds are added into the treatment chamber 1 through the magnetic seed inlet 11. The magnetic seeds are circulated in the treatment chamber 1 by the magnetic seed inlet pump 2, and after fully contacting the suspended matter in the wastewater, flocculants are formed. Then, the flocculants are transported from the treatment chamber 1 to the deflocculator 4 through the extraction and transport mechanism 3, where the flocculants are decomposed into magnetic seeds and suspended matter. The wastewater treated by the magnetic seeds flows out from the wastewater outlet 13 and continues to undergo other wastewater treatment processes. By setting up this structure, magnetic seeds can be added to wastewater to adsorb suspended solids, and the flocs can be removed in time and decomposed into magnetic seeds and suspended solids by the deflocculator 4. This shortens the residence time of magnetic seeds in the wastewater treatment process, allowing the magnetic seeds to be separated and reused in a timely manner. On the other hand, since the flocs are extracted from the wastewater in advance, the energy consumption of subsequent wastewater treatment processes can be reduced. This effectively solves the problems of low reuse efficiency and high energy consumption in the wastewater treatment process caused by the lag in magnetic seed recovery in the existing technology.

[0023] Optionally, the magnetic seed inlet 11 is located on one side of the magnetic seed inlet pump 2.

[0024] Exemplary, in embodiments of this utility model, such as Figure 3 As shown, if the magnetic seed inlet 11 is located above the seed pump 2, it is easy for the magnetic seeds that have just been put into the treatment chamber 1 to collide with the impeller 22, thereby damaging the magnetic seed inlet pump 2. Therefore, the magnetic seed inlet 11 is set on one side of the magnetic seed inlet pump 2, so that the magnetic seed inlet pump 2 can provide a circulating driving force for the magnetic seeds and extend the service life of the magnetic seed inlet pump 2, thereby improving the service life of this wastewater treatment device.

[0025] Optionally, a ramp baffle 14 is provided inside the processing chamber 1, and the magnetic seed dispensing pump 2 is positioned toward the ramp baffle 14.

[0026] Exemplary, in embodiments of this utility model, such as Figure 3 As shown, the inclined baffle 14 is tilted upwards in front of the magnetic seed dispensing pump 2, so that the magnetic seed is driven by the magnetic seed dispensing pump 2 and moves onto the inclined baffle 14, where it stays. This prolongs the residence time of the magnetic seed in the treatment chamber 1, allowing the magnetic seed to mix and adsorb more fully with the suspended solids in the wastewater, thereby improving the utilization rate of the magnetic seed.

[0027] Optionally, magnetic seed dispensing pumps 2 and magnetic seed dispensing ports 11 are provided on both sides of the processing chamber 1.

[0028] Exemplary, in embodiments of this utility model, such as Figure 3 As shown, by providing magnetic seed dispensing pumps 2 and magnetic seed dispensing ports 11 on both sides of the treatment chamber 1, and by providing two inclined baffles 14 in the treatment chamber 1 corresponding to the two magnetic seed dispensing pumps 2 respectively, the efficiency of magnetic seed adsorption is doubled, thereby improving the treatment efficiency of this wastewater treatment device.

[0029] Optionally, the extraction and transport mechanism 3 includes a support disc 31, permanent magnet columns 32, nozzles 33, and a collection chute 34. The upper end of the processing chamber 1 is open. The support disc 31 is vertically and rotatably mounted at the opening. Multiple permanent magnet columns 32 are vertically mounted on the support disc 31 and are evenly spaced along the circumference of the support disc 31. The nozzles 33 are located above the support disc 31. The collection chute 34 is located inside the annulus formed by the permanent magnet columns 32. A connecting pipe 35 is provided at the bottom of the collection chute 34 and is connected to the input end of the deflocculator 4.

[0030] Exemplary, in embodiments of this utility model, such as Figure 1 , Figure 3 and Figure 7As shown, the most widely used permanent magnet is neodymium iron boron, which is divided into sintered neodymium iron boron and bonded neodymium iron boron. Since bonded neodymium iron boron has magnetic properties in all directions and is corrosion resistant, according to the alkaline conditions of the waste liquid and the requirements to be achieved for adsorption, the permanent magnet column 32 in this embodiment adopts a bonded permanent magnet material that does not require plating, is corrosion resistant, and can form the required magnetic field arrangement. The collecting chute 34 is fixedly connected to the processing chamber 1. A second motor 311 is provided on one side of the supporting disc 31. The motor shaft of the second motor 311 is connected to the center of the supporting disc 31. The second motor 311 drives the supporting disc 31 to rotate. A ring of permanent magnet columns 32 is provided on the outer edge of the supporting disc 31. The permanent magnet columns 32 at the bottom of the supporting disc 31 are located inside the processing chamber 1. The flocculent is adsorbed by the adsorption permanent magnet columns 32 and rotates with the supporting disc 31 to the top of the collecting chute 34. The nozzle 33 is connected to a water pump 331. The water pump 331 starts the nozzle 33 to spray a high-pressure water jet toward the permanent magnet columns 32 on the supporting disc 31, knocking the flocculent into the collecting chute 34. Then, it is transported to the deflocculator through the connecting pipe 35 at the bottom of the collecting chute 34. By setting up this structure, the continuous rotation of the supporting disc 31 allows for the continuous adsorption and transport of flocculants into the deflocculator 4. The suction force for adsorbing flocculants is adjusted by changing the depth of the permanent magnet column 32 submerged in the wastewater within the treatment chamber 1, ensuring that the magnetic field can fully adsorb suspended matter before it is adsorbed and transported by the permanent magnet column 32. In this embodiment, permanent magnet columns 32 and collection troughs 34 can be set on both sides of the supporting disc 31 to improve wastewater treatment efficiency. In this embodiment, only the second motor 311 and the water pump 331 need to be started to achieve the adsorption and transport of flocculants, resulting in a simple structure and convenient operation, thus improving the ease of operation of this wastewater treatment device.

[0031] Optionally, a protective cover 36 is provided on one side of the support disk 31 where the permanent magnet column 32 is located. The protective cover 36 is fixedly connected to the processing chamber 1 and is sleeved on the outside of the permanent magnet column 32. Processing holes 361 are opened at the top and bottom of the protective cover 36.

[0032] Exemplary, in embodiments of this utility model, such as Figure 5As shown, by setting up the protective cover 36, flocculants can be prevented from falling off the permanent magnet column 32 when the support disk 31 rotates. When the permanent magnet column 32 rotates to the bottom of the support disk 31, it comes into contact with the wastewater in the treatment chamber 1 through the treatment hole 361 located at the bottom of the protective cover 36, thereby adsorbing the flocculants; when the permanent magnet column 32 rotates to the top of the support disk 31, it receives the flushing from the nozzle 33 through the treatment hole 361 located at the top of the protective cover 36, causing the flocculants on the permanent magnet column 32 to fall into the collection chute 34. By setting up the protective cover 36, during the rotation of the support disk 31, only the permanent magnet column 32 located at the treatment hole 361 can contact the outside, while the permanent magnet columns 32 in other parts are located inside the protective cover 36, reducing the possibility of flocculants falling off during rotation and transportation, thereby further improving the treatment efficiency of this wastewater treatment device.

[0033] Optionally, the permanent magnet column 32 is arranged in multiple rings along the radial direction of the supporting disk 31.

[0034] Exemplary, in embodiments of this utility model, such as Figure 6 As shown, by setting up multiple rings of permanent magnet columns 32, the extraction and transport mechanism 3 can simultaneously adsorb and transport more flocculants, thereby further improving the treatment efficiency of this wastewater treatment device.

[0035] Optionally, the permanent magnet columns 32 in each ring are arranged in multiple rows radially along the support disk 31 and are evenly distributed in a fan shape along the circumference of the support disk 31.

[0036] Exemplary, in embodiments of this utility model, such as Figure 6 As shown, the permanent magnet columns 32 are distributed on the supporting disk 31 in a gradually dispersed pattern from the inside out, which can ensure the distribution density. Since the nozzle 33 sprays water from top to bottom, the sprayed water column first passes through the permanent magnet columns 32 in the outer ring and then through the permanent magnet columns 32 in the inner ring. This distribution pattern makes the outer ring sparser than the inner ring. The permanent magnet columns 32 are arranged in multiple rows radially along the supporting disk 31, and a channel is formed between two adjacent permanent magnet columns arranged radially, which helps the nozzle 33 penetrate from the outer ring to the inner ring, ensuring the efficiency of magnetic seed recovery.

[0037] Optionally, the output end of the deflocculator 4 is provided with a vibration separation mechanism 5. The vibration separation mechanism 5 includes a ramp 51, a vibration module 52 and a spring 53. The top of the ramp 51 is connected to the output end of the deflocculator 4, and the vibration module 52 and the spring 53 are located at the bottom of the ramp 51. The vibration module 52 is used to drive the ramp 51 to vibrate.

[0038] Exemplary, in embodiments of this utility model, such as Figure 8 and Figure 9As shown, after the flocculants are separated by the deflocculator 4, a vibration separation mechanism 5 is installed at the output end of the deflocculator 4 to ensure more thorough separation of the magnetic seeds and suspended matter. The vibration module 52 can be a cylinder. When the magnetic seeds and suspended matter slide onto the slope 51, the vibration module 52 causes the slope 51 to vibrate. Springs 53 are installed at four positions on the front and rear sides of the slope 51. Under the action of the springs 53, the device vibrates stably and continuously during the vibration process. The surface of the slope 51 can be designed to be streamlined to ensure the fluidity of the magnetic seeds and suspended matter and reduce the possibility of them adhering to the slope 51. By setting the vibration separation mechanism 5, the magnetic seeds and suspended matter that have not been completely separated can be completely separated, preventing the magnetic seeds and suspended matter from adhering together, thereby improving the magnetic seed recovery rate.

[0039] Optionally, the output end of the vibration separation mechanism 5 is provided with a conveyor belt 6, the input end of the conveyor belt 6 is connected to the bottom end of the ramp 51, and the output end of the conveyor belt 6 is provided with a magnetic seed recovery box 61 and a suspended matter recovery box 62 in sequence along the conveying direction of the conveyor belt 6. The rotating shaft of the output end of the conveyor belt 6 is a magnetic component.

[0040] Exemplary, in embodiments of this utility model, such as Figure 9 As shown, baffles are provided on both sides of the conveyor belt 6 to prevent magnetic seeds and flocculants from falling outside the conveyor belt 6. After passing through the vibration separation mechanism 5, the magnetic seeds and flocculants are completely separated and roll onto the conveyor belt 6. The conveyor belt 6 transports the magnetic seeds and flocculants. The shaft at the output end of the conveyor belt 6 is a magnetic component. Due to the magnetic force of the magnetic component, the magnetic seeds have a small initial velocity when sliding out of the output end of the conveyor belt 6, thus falling into the magnetic seed collection box 61, which is closer to the output end of the conveyor belt 6. The suspended matter, not affected by other forces, has a larger initial velocity when sliding out of the output end of the conveyor belt 6, thus falling into the suspended matter collection box 62, which is farther from the output end of the conveyor belt 6. By setting this structure, after passing through this wastewater treatment device, the magnetic seeds and flocculants are automatically sorted and placed into different collection boxes, thereby further improving the operational convenience of this wastewater treatment device.
