Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment equipment, and more specifically, particularly relates to a dye sewage treatment equipment for textile production. Background Art

[0002] With the rapid development of the textile industry, the discharge of textile sewage is increasing continuously. It contains a large number of pollutants such as organic matters, dyes, oils and fats, and fiber scraps. If directly discharged, it will cause serious pollution to the environment and even damage the ecological balance. Therefore, the treatment and purification of textile sewage have become urgent problems to be solved in the sustainable development of the textile industry.

[0003] Currently, for the dye sewage treatment equipment used in textile production, it is found that there are at least the following technical problems: 1. The existing sewage treatment equipment has low filtration efficiency and is easy to be blocked: During the textile production process, the dye sewage contains a large number of large particle suspensions (such as fibers, lint, etc.) and fine impurities. Traditional sewage treatment equipment usually adopts a fixed filter screen or a single-direction rotating filtering device. When dealing with high-concentration suspensions, such a design is prone to blockage on the surface of the filter screen due to the accumulation of impurities, reducing the filtration efficiency. At the same time, it requires frequent manual cleaning, increasing the maintenance cost and equipment downtime. In addition, the existing filtering device lacks a dynamic adjustment function and is difficult to adapt to the characteristics of large fluctuations in the quality of textile sewage, resulting in unstable loads on subsequent treatment units (such as coagulation sedimentation tanks) and affecting the overall treatment effect.

[0004] 2. It is difficult to clean the sediment at the bottom of the pool and the lint collection efficiency is low: In the traditional textile dye sewage treatment system, sediment layers often form at the bottom of the sewage regulation tank and the coagulation sedimentation tank due to the settlement of suspended substances. If not cleaned in time, it will cause problems such as pipeline blockage and equipment corrosion. Existing technologies mostly rely on manual scraping or high-pressure flushing devices for bottom cleaning of the pool, which is not only cumbersome in operation but also not thoroughly cleaned, and is prone to cause secondary pollution. At the same time, if the lint (such as fiber flocs) generated in textile sewage is not centrally collected, it will enter subsequent treatment links with the water flow, resulting in blockage of the filter screen or affecting the coagulation effect. Existing equipment generally lacks an automatic lint collection function and requires manual salvage regularly, with high labor intensity and low efficiency. Summary of the Invention

[0005] In order to solve the above technical problems, the invention provides a dye sewage treatment equipment for textile production to solve the above problems.

[0007] Preferably, the separation mechanism includes a filter mesh cylinder. A rotating shaft is fixedly installed at the right end of the filter mesh cylinder. A sealing side plate is sleeved on the circumferential surface of the rotating shaft through a bearing. The filter mesh cylinder is slidably installed through the filter cylinder. The sealing side plate is fixedly installed on the filter cylinder by bolts. A sealing gasket is provided between the sealing side plate and the filter cylinder. The connecting shaft is fixedly installed at the side end of the filter mesh cylinder. A collecting plate is provided inside the filter cylinder. A mounting plate is fixedly installed on the collecting plate. The mounting plate is fixedly connected to the filter cylinder by bolts. A brush rod is provided at the upper end of the collecting plate.

[0008] Preferably, the stirring mechanism includes a second bevel gear fixedly installed through the circumferential surface of the rotating rod. Two third bevel gears are meshed on the circumferential surface of the second bevel gear. Stirring blades are fixedly installed at the separating ends of the two third bevel gears. The two stirring blades are respectively rotatably installed through the upper and lower sides of the fixed circular sleeve by rotating shafts.

[0009] Preferably, the cleaning mechanism includes two second spur gears. Scraping plates are fixedly installed on the two second spur gears. The two scraping plates are both attached to the bottom of the inner wall of the sewage regulation pool opened in the sewage treatment pool. A second gear transmission belt is meshed on the circumferential surfaces of the two second spur gears. A third spur gear is meshed on the inner wall of the second gear transmission belt. A connecting rod is fixedly installed on the third spur gear. A fourth bevel gear is fixedly installed on the connecting rod. A first bevel gear is meshed on the fourth bevel gear. A spur gear ratchet assembly is provided on the first bevel gear. A ratchet structure is provided inside the spur gear ratchet assembly. The inner ring of the ratchet structure of the spur gear ratchet assembly is fixedly connected to the first bevel gear. The outer ring of the ratchet structure of the spur gear ratchet assembly is meshed with a first gear transmission belt. The inner wall of the first gear transmission belt is meshed with the first spur gear.

[0010] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by setting a rotatable filter screen cylinder and its sealing side plates and sealing gaskets, large particulate suspensions such as fibers and lint in textile wastewater can be efficiently removed. The forward rotation design of the filter screen cylinder can direct impurities to the bottom of the filter cylinder, preventing their accumulation and blockage of the filter surface, thereby significantly improving the filtration efficiency and extending the service life of the equipment. At the same time, the sealing side plates are fixedly installed on the filter cylinder by bolts and are provided with sealing gaskets, effectively preventing sewage leakage, ensuring the safety and sealing of the equipment operation, and reducing the maintenance cost. In addition, the rotation direction of the filter screen cylinder can be adjusted according to actual needs, adapting to both conventional filtration scenarios and enabling lint collection during reverse rotation, reflecting the flexibility and versatility of the structural design.

[0011] In the present invention, through the cooperation of the mounting plate and the collection plate, when the filter screen cylinder rotates in reverse, the lint at the bottom of the filter cylinder can be brought to the brush rod on the collection plate, and the lint is concentrated by winding around the brush rod. This design can complete automatic collection without an additional power device, and the bolt-detachable structure facilitates quick cleaning, greatly improving the convenience and efficiency of lint treatment. At the same time, the brush rod design of the collection plate can efficiently wind the lint, preventing the lint from being dispersed into the sewage again, thereby reducing the burden on subsequent treatment units and further improving the overall effect of sewage treatment. In addition, this function is triggered synchronously with the reverse rotation of the filter screen cylinder, realizing automated operation and reducing the need for manual intervention.

[0012] In the present invention, the rotation of the filter screen cylinder drives the stirring mechanism, which includes a second bevel gear, a third bevel gear and stirring blades, to stir the upper and lower layers of sewage in the sewage regulation tank by using the rotational kinetic energy of the filter screen cylinder. This design eliminates the need for an independent stirring power source, not only reducing energy consumption but also simplifying the equipment structure and achieving efficient utilization of mechanical energy. The stirring blades are respectively installed above and below the fixed circular sleeve, and can stir the upper and lower layers of the sewage regulation tank simultaneously, preventing the suspension from depositing and ensuring uniform water quality. This linkage design not only reduces the energy consumption of the equipment but also, through the ingenious design of mechanical linkage, realizes the compactness and integration of the sewage treatment process, improving the economy and practicality of the equipment.

[0013] In the present invention, the cleaning mechanism includes a second flat gear, a scraper plate and a gear transmission assembly, which can automatically scrape and clean the deposited particulate matter at the bottom of the inner wall of the sewage regulating tank. The cleaning mechanism is controlled by the flat gear ratchet assembly and is started when the filter screen cylinder reverses, effectively removing impurities at the bottom of the pool, avoiding the cumbersome operation of traditional manual cleaning, significantly improving cleaning efficiency and reducing maintenance costs. In addition, the scraper plate in the cleaning mechanism adopts a fitted design, which can closely contact the surface of the bottom of the pool to ensure the thoroughness of the scraping action. At the same time, the gear transmission components of the cleaning mechanism, such as the second gear transmission belt, the third flat gear, etc., realize the stable rotation of the scraper plate through precise meshing transmission, further improving the cleaning effect. This design not only solves the technical problem of difficult removal of sediments at the bottom of the pool during sewage treatment, but also realizes intelligent management of the cleaning process through automatic control.

[0014] In the present invention, through the synchronous triggering mechanism of the cleaning mechanism and the lint collection function, the cleaning mechanism is stationary when the filter screen drum is in the forward rotation state, and the lint collection and pool bottom cleaning are started simultaneously only when it is reversed. This design realizes the automated collaborative operation of lint treatment and pool bottom cleaning, which not only avoids unnecessary energy consumption of the cleaning mechanism, but also ensures the long-term stable operation of the sewage treatment system, further improving the overall treatment efficiency and the level of equipment intelligence. Specifically, when the filter screen drum rotates forward, the ratchet structure of the flat gear ratchet assembly prevents the first bevel gear from rotating, thereby avoiding the cleaning mechanism from starting up by mistake; and when the filter screen drum rotates reversely, the ratchet structure is released, driving the cleaning mechanism to work in conjunction. This synchronous triggering mechanism realizes the efficient coordination of functional modules through the precise control of mechanical transmission, while reducing the energy loss during equipment operation, reflecting the design concept of energy saving and environmental protection.

Detailed implementation manners

[0017] The following further describes in detail the implementation manners of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0018] Please refer to Figures 1-8 , the present invention provides a dye sewage treatment device for textile production, including a sewage treatment tank 21, a sewage regulation tank 31 and a sewage coagulation and sedimentation tank 32 are provided on the sewage treatment tank 21, a separation mechanism for removing large particle suspended matters, fibers and other physical impurities in textile sewage is provided at the side end of the sewage treatment tank 21, a filter cartridge 28 is fixedly installed at the right side end of the sewage treatment tank 21, a water inlet 29 for incoming wastewater is provided on the filter cartridge 28, the sewage regulation tank 31 is used for balancing the water quality and quantity of textile sewage to ensure the stable operation of subsequent treatment units, the sewage coagulation and sedimentation tank 32 is used for coagulating and sedimenting textile sewage, and chemical agents (such as flocculants, coagulant aids) are added therein to make fine suspended particles aggregate into larger particles for easy sedimentation, so as to remove part of the suspended solids and chromaticity, a fixed circular sleeve 19 is fixedly installed on the inner wall of the sewage regulation tank 31 opened on the sewage treatment tank 21, a rotating rod 11 is rotatably installed in the fixed circular sleeve 19, a stirring mechanism is provided on the fixed circular sleeve 19, a limit installation groove is opened at the right side end of the rotating rod 11, a first spur gear 12 is fixedly installed through the rotating rod 11, a cleaning mechanism is provided at the bottom of the inner wall of the sewage treatment tank 21, a connecting shaft 39 is provided at the left side end of the separation mechanism, and the connecting shaft 39 is slidably installed in the limit installation groove opened on the rotating rod 11.

[0019] In this embodiment, as Figure 1 , Figure 2 , Figure 3As shown, the separation mechanism includes a filter mesh cylinder 34. A rotating shaft 38 is fixedly installed at the right end of the filter mesh cylinder 34. A sealing side plate 37 is sleeved on the circumferential surface of the rotating shaft 38 through a bearing. The filter mesh cylinder 34 is slidably installed through the filter cylinder 28. The sealing side plate 37 is fixedly installed on the filter cylinder 28 by bolts. A sealing gasket is provided between the sealing side plate 37 and the filter cylinder 28 to prevent sewage from seeping out. When the sewage is preliminarily treated, it enters the filter cylinder 28 through the water inlet 29 and then passes through the surface of the filter mesh cylinder 34. The filter mesh cylinder 34 can filter large particle suspended matters, fibers and other physical impurities in the sewage and leave these impurities on the outer surface of the filter mesh cylinder 34. Since the side end of the filter mesh cylinder 34 communicates with the sewage regulating tank 31 opened in the sewage treatment tank 21, the sewage after filtration will flow into the sewage regulating tank 31 opened in the sewage treatment tank 21. Moreover, when separating, the rotating shaft 38 can be connected to a power assembly (such as a motor, etc.), and the power assembly makes the rotating shaft 38 drive the filter mesh cylinder 34 to rotate forward, so as to avoid the blockage of the upper part of the circumferential surface of the filter mesh cylinder 34 by impurities. In the case of forward rotation, the impurities on the filter mesh cylinder 34 will fall towards the bottom of the inner wall of the filter cylinder 28. The connecting shaft 39 is fixedly installed at the side end of the filter mesh cylinder 34.

[0020] In this embodiment, as Figure 1 , Figure 2 , Figure 3 shown, a collecting plate 36 is provided inside the filter cylinder 28. An installation plate 35 is fixedly installed on the collecting plate 36. The installation plate 35 is fixedly connected to the filter cylinder 28 by bolts. A brush rod is provided at the upper end of the collecting plate 36 to collect a large amount of fluff remaining in the textile sewage. When collecting the fluff, the rotating shaft 38 and the filter mesh cylinder 34 are in a reverse rotation state. Moreover, a brush is also provided on the surface of the filter mesh cylinder 34. When the filter mesh cylinder 34 rotates in the reverse direction, the fluff at the bottom of the filter cylinder 28 will be brought to the position of the collecting plate 36. At this time, these fluff come into contact with the brush rod on the collecting plate 36, and these fluff can be well wound, thus completing the centralized collection of the fluff. Moreover, after the collection is completed, the bolts can be disassembled, and the installation plate 35 and the collecting plate 36 can be taken out of the filter cylinder 28 for cleaning.

[0021] In this embodiment, as Figure 4 , Figure 5 , Figure 6As shown, the stirring mechanism includes a second bevel gear 16, which is fixedly installed through the circumferential surface of the rotating rod 11. Two third bevel gears 17 are meshed with the circumferential surface of the second bevel gear 16. Stirring blades 18 are fixedly installed at the separated ends of the two third bevel gears 17. The two stirring blades 18 are respectively rotatably installed through the upper and lower sides of the fixed circular sleeve 19 by rotating shafts. When the rotating rod 11 is limitedly connected to the connecting shaft 39 through the opened limiting installation groove, the rotation of the filter screen cylinder 34 can drive the rotating rod 11 to rotate, thereby driving the stirring mechanism to rotate, and further enabling the two stirring blades 18 in the stirring mechanism to stir the upper and lower layers in the sewage regulating tank 31 respectively, thereby preventing the suspension from settling and ensuring the uniformity of water quality. This helps to avoid the deposition of pollutants at the bottom of the tank and ensure the consistency of the effluent water quality.

[0022] In this embodiment, as Figure 5 、 Figure 6 、 Figure 7 、 Figure 8As shown in the figure, the cleaning mechanism includes two second spur gears 22. Scraper plates 24 are fixedly installed on both of the two second spur gears 22. Both of the two scraper plates 24 are attached to the bottom inner wall of the sewage regulating tank 31 opened in the sewage treatment tank 21. A second gear belt 23 meshes with the circumferential surfaces of the two second spur gears 22. A third spur gear 25 meshes with the inner wall of the second gear belt 23. A connecting rod 26 is fixedly installed on the third spur gear 25. A fourth bevel gear 27 is fixedly installed on the connecting rod 26. A first bevel gear 15 meshes with the fourth bevel gear 27. A spur gear ratchet assembly 14 is provided on the first bevel gear 15. A ratchet structure (the ratchet structure is a prior art, such as the structure in the publication number CN105736664B) is provided inside the spur gear ratchet assembly 14. The inner ring of the ratchet structure of the spur gear ratchet assembly 14 is fixedly connected to the first bevel gear 15. The outer ring of the ratchet structure of the spur gear ratchet assembly 14 meshes with a first gear belt 13. The inner wall of the first gear belt 13 meshes with a first spur gear 12. When it is not necessary to clean the bottom inner wall of the sewage regulating tank 31, the rotating rod 11 is in a forward rotation state. Under the action of the ratchet structure inside the spur gear ratchet assembly 14, the first bevel gear 15 will not rotate, so that the first bevel gear 15 and the two scraper plates 24 will not rotate. When the fluff is collected and cleaned inside the filter cylinder 28, the bottom inner wall of the sewage regulating tank 31 opened in the sewage treatment tank 21 can be cleaned synchronously. The reverse rotation of the rotating rod 11 can drive the ratchet mechanism of the spur gear ratchet assembly 14 to rotate. The spur gear ratchet assembly 14 drives a series of structures such as the first bevel gear 15, the fourth bevel gear 27, and the connecting rod 26 to rotate, so that the two scraper plates 24 can be driven to rotate. The two scraper plates 24 can scrape the bottom inner wall of the sewage regulating tank 31 opened in the sewage treatment tank 21, so that the bottom of the regulation can be cleaned. In the sewage regulating tank 31 opened in the sewage treatment tank 21, although there is the stirring action of the stirring mechanism, some particulate matters (especially larger or denser particles) may still gradually settle to the bottom of the tank due to the action of gravity, resulting in the accumulation of impurities at the bottom of the tank. At this time, the cleaning mechanism can be used to clean it. Moreover, the cleaning mechanism only rotates when the filter screen cylinder 34 rotates in reverse to remove fluff, and does not rotate when the sewage quality is normally regulated.

[0023] Working principle: First step, preliminary filtration stage: The textile sewage first enters the filter cylinder 28 through the water inlet 29 and is preliminarily filtered through the surface of the filter screen cylinder 34. The filter screen cylinder 34 can effectively remove large particle suspended matters, fibers and other physical impurities in the sewage. During this process, if the filter screen cylinder 34 rotates forward, these impurities can be prevented from blocking the circumferential surface of the filter screen cylinder 34, and the impurities can be allowed to naturally settle to the bottom of the filter cylinder 28.

[0024] Step 2, adjusting water quality and quantity: The sewage after preliminary filtration flows into the sewage regulating tank 31 in the sewage treatment tank 21. Its function here is to balance the water quality and quantity of textile sewage and ensure the stable operation of subsequent treatment units.

[0025] Step 3, coagulation and sedimentation treatment: The sewage then enters the sewage coagulation and sedimentation tank 32. In this step, chemical agents (such as flocculants and coagulant aids) are added to promote the aggregation of fine suspended particles into larger particles for easy sedimentation, thereby removing some suspended solids and colority.

[0026] Step 4, stirring operation: A stirring mechanism is provided inside the sewage regulating tank 31, including components such as a second bevel gear 16, a third bevel gear 17, and a stirring blade 18. When the rotating rod 11 is linked with the filter mesh cylinder 34 through the connecting shaft 39, the rotation of the filter mesh cylinder 34 will drive the rotating rod 11 and the stirring mechanism thereon to work. The two stirring blades 18 respectively stir the upper and lower layers in the sewage regulating tank 31 to prevent the suspension from settling and ensure uniform water quality.

[0027] Step 5, cleaning mechanism: A cleaning mechanism is provided at the bottom of the sewage treatment tank 21, including components such as a second spur gear 22 and a scraping plate 24. Usually, when the rotating rod 11 is in the forward rotation state, the first bevel gear 15 will not rotate, so the scraping plate 24 will not act either; but when it is necessary to remove the fluff, the filter mesh cylinder 34 rotates in reverse, which will trigger the spur gear ratchet assembly 14 to make the first bevel gear 15 rotate, and then drive the scraping plate 24 to clean the impurities accumulated at the bottom of the sewage treatment tank 21.

[0028] Step 6, fluff collection: In a specific operation mode, the filter mesh cylinder 34 rotates in reverse to bring the fluff at the bottom to the position of the collection plate 36, and the fluff is concentrated by winding around the brush rod. After completion, the mounting plate 35 and the collection plate 36 can be easily removed by removing the bolts for cleaning.

[0029] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.
