Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of continuous treatment of wastewater in the production of water-based glue for cigarettes, and particularly relates to a continuous wastewater treatment device in the production of water-based glue for cigarettes. BACKGROUND

[0002] In the production of water-based glue for cigarettes, industrial wastewater with complex components is continuously generated due to the dissolution, emulsification, mixing and cleaning of raw materials such as polyvinyl alcohol, acrylate and thickening agent, etc. The wastewater contains a large amount of high-molecular organic matter, colloidal particles, residual chemicals and suspended impurities. If the wastewater is directly discharged without effective treatment, it will not only cause a significant increase in the COD and BOD values of the water body, leading to eutrophication and damaging the ecological environment, but also increase the load of the subsequent municipal sewage treatment system due to the difficulty in natural degradation of pollutants, which does not meet the environmental protection discharge standards for industrial production.

[0003] The existing device mainly relies on manual pouring or uses a simple feeding structure with a single valve pipe to add chemicals. The chemicals fall only by controlling the opening and closing of the valve pipe, which lacks precise and uniform addition and mixing design. This method causes the chemicals and wastewater to be difficult to fully mix, resulting in poor mixing uniformity, and easy to cause local high or low concentration of chemicals, which in turn causes insufficient reaction of colloidal particles, organic matter and other pollutants, and incomplete flocculation and precipitation. The residual impurities in the wastewater directly affect the effect of subsequent purification processes such as sedimentation and air flotation, resulting in unstable and non-standard final effluent quality, and increasing the treatment cost and environmental protection risk.

[0041] Working principle: when the cigarette water-based glue production wastewater is continuously introduced into the sedimentation tank 1 through the water inlet pipe 2 at one end of the sedimentation tank 1, the dosing assembly is started: first, pull open the top cover to expose the feeding area below the reagent tank 7, then open the hinged cover plates on both sides of the top plate of the reagent tank 7, add sewage treatment reagents such as flocculants into the reagent tank 7, and after the feeding is completed, the top cover can be slid back to reduce the evaporation of reagents or the falling of impurities, then the third motor on the top surface of the top plate is started, the third motor output shaft drives the rotating rod 12 to rotate, the spiral blades 8 at the dosing pipe of the reagent tank 7 and the blocking plates 9 fixed between the intervals thereof rotate synchronously; when the blocking plate 9 at the inclined end of the dosing pipe rotates to the bottom end, the blocking plate 9 closes the dosing pipe, at this time, the guide channel at the bottom of the blocking plate 9 above it begins to guide the reagents to the closed area for temporary accumulation; as the rotating rod 12 continues to rotate, the blocking plate 9 closing the dosing pipe gradually leaves the inclined opening, the dosing opening is opened, and the accumulated reagents begin to fall, when the next blocking plate 9 at the inclined end of the dosing pipe rotates to the bottom end, it is closed again, and the quantitative dosing is completed; by controlling the rotation angle and speed of the third motor, the single dosing amount and dosing speed can be accurately controlled, and the reagents can be accurately and uniformly dosed; further, the reagents and wastewater can be stably proportioned, in the process, the connecting rods fixed on both sides of the rotating rod 12 drive the disc to rotate with the rotating rod 12, the spring 10 in the disc contraction groove pushes the protrusion 11 to extend out, and the protrusion 11 continuously impacts the inner wall of the reagent tank 7 on both sides during rotation, shakes off the reagent residues adhered to the wall, avoids the reagent caking and blocking the dosing pipe, and ensures that the reagents are fully utilized; after the reagents and wastewater are preliminarily collected in the sedimentation tank 1, the first motor on the mounting plate on the top surface of the sedimentation tank 1 is started, the first motor output shaft extends into the sedimentation tank 1, drives the coaxially fixed rotating shaft to rotate, and the multiple stirring paddles 13 fixed at equal intervals on the rotating shaft rotate, so that the reagents and wastewater are fully stirred and mixed, the macromolecular organic matter, colloidal particles and suspended impurities in the reagents and wastewater are uniformly contacted, and the flocculation body is formed, the mixed wastewater flows to the direction of the partition plate of the inner wall of the sedimentation tank 1 under the action of the stirring force, and finally enters the subsequent area through the flow-through groove at the lower end of the partition plate, part of the flocculation body with relatively large density naturally precipitates during the flow process, falls into the inclined plate on the inner bottom surface of the sedimentation tank 1, slides to the flange blowdown valve pipe direction along the inclined plate, can be discharged by opening the flange blowdown valve pipe, and the preliminary precipitation and impurity removal are completed.

[0042] Wastewater entering the flotation zone between the partition plate and the overflow plate is fed into the dissolved air tank 5 on one side of the sedimentation tank 1. The dissolved air water produced by the dissolved air tank 5 is transported through a flange pipe to a horizontal pipe installed above the flotation zone, and then through two air pipes on the bottom of the horizontal pipe to the lower end of the flotation zone. Multiple air outlets on the outer wall of the air pipes release fine air bubbles evenly. The air bubbles fully contact and adsorb the unsedimented fine flocs and suspended impurities in the wastewater, forming a flotation mass with a density less than water. This flotation mass rises to the surface of the wastewater with the air bubbles, forming scum. At this point, the sedimentation tank 1 is activated. The outer wall is used to drive the geared motor of the chain skimmer 4. The geared motor drives the chain skimmer 4 installed on both sides of the top of the sedimentation tank 1. The rubber plate of the chain skimmer 4 scrapes the scum on the surface of the wastewater toward the sludge box 3 at one end of the sedimentation tank 1. Finally, the scum is scraped into the sludge box 3 for collection, completing the air flotation separation and impurity removal. The purified water passes over the overflow plate and part of it is transported through the clear water return pipe at one end of the dissolved air tank 5 to the lower end of the sludge box 3 inside the sedimentation tank 1, providing a circulating water source for the dissolved air tank 5 and realizing the reuse of water resources.

[0043] When the scum and sediment sludge collected in sludge box 3 accumulate to a certain amount, the second motor on the two vertical plates at the top of sludge box 3 is started. The output shaft of the second motor drives the lead screw between the two vertical plates to rotate. The sliding sleeve on the lead screw and guide rod moves downward along the lead screw. The connecting plate on the bottom of the sliding sleeve drives the scraper 6 to move downward synchronously. The shape of the scraper 6 is adapted to the inner wall of sludge box 3, and the rubber strip fixed to its contact surface is tightly attached to the inner wall of sludge box 3. During the downward movement, the sludge attached to the inner wall of sludge box 3 can be completely scraped off. The scraped sludge is discharged through the flange sludge discharge pipe connected to sludge box 3 through the outer wall of sedimentation tank 1, completing the automatic sludge cleaning. After cleaning, the second motor reverses and drives the lead screw to rotate. The sliding sleeve drives the scraper 6 to move upward and reset, without affecting the wastewater treatment process, ensuring continuous operation of the device. At this point, the device is used successfully.

[0044] Example 2: See Figures 5 to 6 Unlike Example 1, the stirring paddle 13 is a movable structure on the rotating shaft;

[0045] The stirring paddle 13 is installed on the connecting ring, the connecting ring is sleeved on the outside of the rotating shaft, the mounting groove 15 is formed on the outer wall of the rotating shaft corresponding to the position of the connecting ring, the limiting block is integrally formed on the inner side of the connecting ring corresponding to the position of the mounting groove 15, the adjusting push rod is arranged in the mounting groove 15, one end of the adjusting push rod is installed on the inner wall of the mounting groove 15, the other end is installed on the limiting block, the length of the adjusting push rod is changed to move the connecting ring up and down on the outside of the rotating shaft, two rotating discs 14 are installed between the adjacent stirring paddles 13 on the outer wall of the rotating shaft, the through holes are formed on the rotating discs 14, the one-way structure and the filtering structure are arranged at the positions of the through holes of the upper and lower rotating discs 14, the one-way structure allows one rotating disc 14 to absorb liquid inward when the flexible hose is stretched, and the other rotating disc 14 to discharge liquid outward when the flexible hose is compressed, the filtering structure allows only liquid to flow at the position of the through hole, the flexible hose is connected between the two rotating discs 14, one rotating disc 14 is fixedly connected with the rotating shaft, and the other rotating disc 14 is slidably connected with the rotating shaft, (the stirring paddles 13 are numbered from top to bottom, the rotating disc 14 close to the position of the stirring paddle 13 with an even number is a movable structure, and the rotating disc 14 far from the position of the stirring paddle 13 with an even number is a fixed structure), when the stirring paddles 13 move up and down, the rotating disc 14 at the corresponding position moves, the flexible hose discharges the absorbed liquid when being compressed, the discharged liquid washes the mounting groove 15, and the medicine falling into the mounting groove 15 is discharged for mixing; after the flexible hose is compressed, the flexible hose absorbs liquid outside through the elasticity of the flexible hose.

[0046] The control box of the continuous treatment device is internally provided with an intelligent control assembly, which comprises an acquisition module, an analysis module and an execution module.

[0047] The acquisition module acquires the width data of the stirring paddle 13, acquires the medicine concentration data in the sedimentation tank 1, acquires the wastewater viscosity and stirring speed, and transmits the acquired data to the analysis module.

[0048] The analysis module receives the data transmitted by the acquisition module and pre-processes the data, determines the spacing range between the stirring paddles 13 according to the transmission characteristics of the stirring force, analyzes the medicine concentration data to obtain the mixing uniformity, judges the optimal spacing through the mixing uniformity, the wastewater viscosity and the stirring speed, generates an adjustment signal when the mixing uniformity is less than a threshold value, and transmits the adjustment signal to the execution module; the execution module determines the adjustment mode of the stirring paddle 13 according to the optimal spacing and the spacing range.

[0049] When the distance between the upper and lower agitator blades 13 is fixed, the transmission of axial thrust decreases with distance. If the distance is too large (e.g., exceeding 1.5 times the width of the agitator blade 13), the axial thrust of the upper and lower blades cannot be effectively superimposed, and the wastewater flow velocity in the middle area decreases significantly, forming a "mixing blind zone."
