Description

Technical Field

[0001] This invention relates to the field of dyeing and printing wastewater recycling and treatment technology, specifically to a wastewater recycling and treatment device for fabric dyeing and printing. Background Technology

[0002] In the textile industry, dyeing and finishing wastewater mainly originates from the pretreatment, dyeing, printing, and finishing processes of cotton, wool, linen, silk, chemical fiber, or blended products. This wastewater contains large amounts of dyes, sizing agents, and other complex chemical components, posing a serious threat to the environment. With increasing environmental awareness and stricter wastewater discharge standards, the treatment and recycling of dyeing and finishing wastewater has become particularly important.

[0003] The treatment of dyeing and printing wastewater typically involves a series of chemical reactions and physical filtration steps. Currently, wastewater treatment facilities suffer from several efficiency issues when adding reactants. For example, reactants added to the wastewater at once may not mix thoroughly before settling to the bottom, affecting the completeness of the reaction. Furthermore, filter plates are prone to clogging after long-term use, requiring manual cleaning and replacement, which increases maintenance costs and also impacts treatment efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a waste liquid recycling and treatment device for fabric printing and dyeing, so as to solve at least one technical problem existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a waste liquid recycling and treatment device for fabric printing and dyeing, comprising a tank, an inner cavity opened inside the tank, and a motor adapted to be installed at the top of the tank. The output end of the motor is fixedly connected to a rotating rod, and a disc is fixedly connected to the outer side of the rotating rod. A transmission rod is slidably connected inside the tank, and a mounting plate is fixedly connected to the bottom end of the transmission rod. The filter plate is rotatably connected inside the mounting plate, the top end of the transmission rod is hemispherical, and the bottom end of the inner cavity is inverted conical.

[0006] Preferably, the bottom of the tank is fixedly connected to a support leg, the outside of the tank is provided with a slot, the slot is configured in four groups, and the bottom of the tank is fixedly connected to a drain pipe.

[0007] Preferably, a first solenoid valve is adapted to be installed at the bottom of the inner cavity, and a second solenoid valve is adapted to be installed inside the drain pipe. The first solenoid valve and the second solenoid valve are electrically connected to the host computer.

[0008] Preferably, a mounting bracket is provided at the top of the tank, and bolts are threaded to both sides of the mounting bracket. The mounting bracket is installed at the top of the tank by means of the bolts, and the motor adapter is installed at the top of the mounting bracket.

[0009] Preferably, a mounting sleeve is fixedly connected to the outer side of the rotating rod, and a stirring rod is fixedly connected to the outer side of the mounting sleeve. The stirring rod is set to at least five groups, and the number of stirring rods in each group is four. The stirring rod is located inside the inner cavity.

[0010] Preferably, a connecting pipe is fixedly connected to the top of the disc, a funnel is fixedly connected to the top of the connecting pipe, a circular hole is formed at the bottom of the disc, an annular groove is formed at the bottom of the disc, and a groove is formed at the bottom of the disc. The connecting pipe is rotatably connected to the tank body.

[0011] Preferably, a telescopic rod is fixedly connected to the top of the filter plate, and the telescopic rod is slidably connected to the bottom of the rotating rod.

[0012] Preferably, an outer ring is fixedly connected to the outer side of the transmission rod, and a spring is sleeved on the outer side of the transmission rod; One end of the spring is connected to the bottom end of the outer ring, the other end of the spring is connected to the inside of the tank, and the transmission rod is engaged with the groove.

[0013] Preferably, the mounting plate is internally fixedly connected with partitions, which are configured in four groups, and four mounting cavities are formed by the four groups of partitions. Each group of mounting cavities is designed to correspond one-to-one with each group of slots.

[0014] Preferably, a collection box is fitted inside the mounting cavity, and a handle is fixedly connected to the outside of the collection box. A total of four collection boxes are configured.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: First, in the process of treating dyeing and printing wastewater, the reactants are gradually added into the funnel, and the rotating rod and stirring rod driven by the motor are used for stirring, ensuring that the reactants and wastewater are fully mixed. Simultaneously, the rotating rod drives the disc to generate centrifugal force, rapidly dispersing the reactants into the dyeing and printing wastewater through the circular holes at the bottom of the disc, improving the addition efficiency. The design of the annular trough ensures that all reactants fall into the inner cavity, avoiding waste. After the reaction is completed, the wastewater is controlled by the first and second solenoid valves to flow through the filter plate for filtration, removing impurities, and finally the filtered wastewater is discharged into the storage tank. This process not only improves the addition efficiency of the reactants but also enhances the overall treatment efficiency of the dyeing and printing wastewater.

[0016] II. In the system for treating dyeing and printing wastewater, the telescopic rod is connected to the rotating rod. The rotation of the rotating rod drives the filter plate to rotate, generating centrifugal force that dislodges flocculent matter and impurities from the filter plate surface, preventing clogging and ensuring smooth flow of the wastewater. Simultaneously, the rotation of the disc intermittently compresses the transmission rod through a groove at its bottom. This action, through the cooperation of the outer ring and spring, causes the transmission rod to vibrate, which in turn drives the mounting plate and filter plate to vibrate. This vibration helps loosen residual impurities on the filter plate, and combined with the centrifugal force generated by the rotation, effectively removes impurities from the filter plate surface, ensuring unobstructed flow and achieving efficient filtration and circulation of the dyeing and printing wastewater.

[0017] Third, in the dyeing and printing wastewater treatment system, the filter plates use centrifugal force to separate impurities and collect them into a collection box. After treatment, users can easily remove the collection box by pulling the handle and clean out the impurities. Compared to traditional methods that require cleaning or replacing filter plates, this design simplifies the operation process, reduces maintenance costs, and thus improves the practicality and economy of the equipment.

[0019] 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. Example

[0020] Please see Figures 1 to 6 The present invention provides a technical solution: a waste liquid recycling and treatment device for fabric printing and dyeing, comprising a tank 1, an inner cavity 2 opened inside the tank 1, and a motor 3 adapted to be installed at the top of the tank 1. The output end of the motor 3 is fixedly connected to a rotating rod 4, and a disc 5 is fixedly connected to the outer side of the rotating rod 4. A transmission rod 7 is slidably connected inside the tank 1, and an installation disc 8 is fixedly connected to the bottom end of the transmission rod 7. The filter plate 6 is rotatably connected inside the mounting plate 8, the top end of the transmission rod 7 is hemispherical, and the bottom end of the inner cavity 2 is inverted conical.

[0021] Furthermore, a support leg 11 is fixedly connected to the bottom end of the tank body 1, and a slot 12 is provided on the outer side of the tank body 1, with four sets of slots 12. A drain pipe 13 is fixedly connected to the bottom end of the tank body 1. Furthermore, a mounting bracket 31 is provided at the top end of the tank body 1, and bolts 32 are threadedly connected to both sides of the mounting bracket 31. The mounting bracket 31 is installed at the top end of the tank body 1 by means of the bolts 32, and the motor 3 is adapted to be installed at the top end of the mounting bracket 31.

[0022] Furthermore, an installation sleeve 41 is fixedly connected to the outer side of the rotating rod 4, and a stirring rod 42 is fixedly connected to the outer side of the installation sleeve 41. The stirring rod 42 is set to at least five groups, and the number of stirring rods 42 in each group is four. The stirring rods 42 are located inside the inner cavity 2.

[0023] Furthermore, a connecting pipe 51 is fixedly connected to the top of the disc 5, a funnel 52 is fixedly connected to the top of the connecting pipe 51, a circular hole 53 is opened at the bottom of the disc 5, an annular groove 54 is opened at the bottom of the disc 5, and a groove 55 is opened at the bottom of the disc 5. The connecting pipe 51 is rotatably connected to the tank body 1.

[0024] When it is necessary to recycle and treat dyeing and printing wastewater, the wastewater is first added into the inner cavity 2 through the funnel 52. Then, reactants are added into the funnel 52. The reactants will accumulate in the connecting pipe 51 and the inside of the funnel 52, and slowly diffuse into the inside of the disc 5. Finally, they fall into the inner cavity 2 through the round hole 53 at the bottom of the disc 5 and react with the dyeing and printing wastewater.

[0025] After the reactants are added into the funnel 52, the motor 3 is started. The operation of the motor 3 will drive the rotating rod 4 at the output end of the motor 3 to rotate. The rotating rod 4 will drive the stirring rod 42 fixed on its outside. The rotating stirring rod 42 will stir the reactants and wastewater that slowly fall into the inner cavity 2. Compared with the traditional method of adding reactants all at once, this method of adding reactants gradually can make the reactants come into more comprehensive contact with the dyeing wastewater when they enter the dyeing wastewater, so that the two can react fully.

[0026] Simultaneously, the rotating rod 4 also drives the disk 5 fixed to its outer side to rotate. The rotating disk generates centrifugal force, which rapidly disperses the reactants located inside the connecting pipe 51 within the disk 5, allowing them to fall into the dyeing wastewater through the circular hole 53 at the bottom of the disk 5. This improves the efficiency of reactant addition and consequently enhances the overall treatment efficiency of the dyeing wastewater. Furthermore, since the reactants falling into the dyeing wastewater through the circular hole are independent, it ensures that each reactant can fully contact the wastewater, guaranteeing a complete reaction.

[0027] With the design of the annular groove 54, even if the reactants do not fall through the circular hole 53 under the action of centrifugal force, they will eventually fall into the inner cavity 2 through the annular groove 54, avoiding waste caused by residue inside the disc 5, and even affecting the recycling and treatment of dyeing and printing waste liquid.

[0028] After the dyeing waste liquid and the reactants have fully reacted, the first solenoid valve 121 and the second solenoid valve 131 are opened by the host computer. At this time, the dyeing waste liquid in the inner cavity 2 will flow down through the first solenoid valve 121 and be filtered by the filter plate 6, thereby filtering out the flocculent matter and other impurities generated by the reaction. The filtered dyeing waste liquid flows into the pre-prepared storage tank through the drain pipe 13.

[0029] In summary, during the treatment of dyeing and printing wastewater, the reactants are gradually added to the funnel 52, and the motor 3 drives the rotating rod 4 and stirring rod 42 to stir, ensuring thorough mixing of the reactants and wastewater. Simultaneously, the rotating rod 4 drives the disc 5 to generate centrifugal force, rapidly dispersing the reactants into the wastewater through the circular hole 53 at the bottom of the disc 5, thus improving the addition efficiency. The design of the annular trough 54 ensures that all reactants fall into the inner cavity 2, avoiding waste. After the reaction is complete, the wastewater is filtered through the filter plate 6 by the first solenoid valve 121 and the second solenoid valve 131 to remove impurities, and finally the filtered wastewater is discharged into the storage tank. This process not only improves the reactant addition efficiency but also enhances the overall treatment efficiency of the dyeing and printing wastewater.

[0030] Example 2 refines the specific process of pipeline heat treatment based on Example 1. For details, please refer to [link / reference]. Figures 1 to 7 ; Furthermore, a telescopic rod 61 is fixedly connected to the top of the filter plate 6, and the telescopic rod 61 is slidably connected to the bottom of the rotating rod 4.

[0031] Furthermore, an outer ring 71 is fixedly connected to the outer side of the transmission rod 7, and a spring 72 is sleeved on the outer side of the transmission rod 7; One end of the spring 72 is connected to the bottom end of the outer ring 71, and the other end of the spring 72 is connected to the inside of the tank 1. The transmission rod 7 is engaged with the groove 55. Since the telescopic rod 61 is slidably connected to the bottom end of the rotating rod 4, the rotating rod 4 will drive the filter plate 6 to rotate through the telescopic rod 61. At this time, the rotating filter plate 6 will generate centrifugal force. Under the action of centrifugal force, the flocculent matter and impurities remaining on the surface of the filter plate 6 will be thrown to the outside of the filter plate 6, thereby effectively preventing the filter plate 6 from clogging and ensuring that the dyeing waste liquid can pass through the filter plate smoothly.

[0032] The rotation of the disc 5 causes the groove 55 at the bottom of the disc 5 to continuously adjust its position. The disc 5, in conjunction with the groove 55, continuously and intermittently compresses the transmission rod 7. When the transmission rod 7 is compressed, it slides down and compresses the spring 72 through the outer ring 71, causing the spring 72 to contract. If the transmission rod 7 is not compressed, the elasticity of the spring 72 causes the transmission rod 7 to return to its original position. This cycle repeats, causing the mounting plate 8 to vibrate through the transmission rod 7, which in turn causes the filter plate 6 to vibrate.

[0033] The vibrating filter plate 6 can loosen the impurities remaining on the surface of the filter plate 6. In conjunction with the rotating filter plate 6, it can effectively shake off the impurities remaining on the surface of the filter plate 6, ensuring the smoothness of the filter plate 6 and realizing the smooth flow of dyeing and printing waste liquid.

[0034] In summary, in the system for treating dyeing and printing wastewater, the telescopic rod 61 is connected to the rotating rod 4, allowing the rotation of the rotating rod 4 to drive the filter plate 6 to rotate, generating centrifugal force. This force dislodges flocculent matter and impurities from the surface of the filter plate 6, preventing clogging and ensuring smooth flow of the wastewater. Simultaneously, the rotation of the disc 5 intermittently compresses the transmission rod 7 through the groove 55 at its bottom. This action, through the cooperation of the outer ring 71 and the spring 72, causes the transmission rod 7 to vibrate, which in turn drives the mounting disc 8 and the filter plate 6 to vibrate. This vibration helps loosen residual impurities on the filter plate, and combined with the centrifugal force generated by the rotation, effectively removes impurities from the surface of the filter plate 6, ensuring unobstructed flow and achieving efficient filtration and circulation of the dyeing and printing wastewater.

[0035] Example 3, based on Example 2 above, is further described in detail, as shown in Figure 8. The specific method is as follows: Furthermore, the mounting plate 8 is internally fixedly connected with partitions 81, which are configured in four groups, and four mounting cavities are formed by the four groups of partitions 81. Each group of mounting cavities is designed to correspond one-to-one with each group of slots 12.

[0036] Furthermore, a collection box 811 is fitted inside the mounting cavity, and a handle 812 is fixedly connected to the outside of the collection box 811. A total of four collection boxes 811 are configured.

[0037] Impurities thrown off by the centrifugal force of the filter plate 6 will enter the collection box 811. After the dyeing and printing waste liquid is treated, the collection box 811 can be removed by pulling the handle 812, and the impurities inside can be cleaned. Compared with the traditional method that requires cleaning or replacing the filter plate, this method is not only simpler and faster to operate, but also has lower maintenance costs, further improving the overall practicality of the equipment.

[0038] In summary, in the dyeing and printing wastewater treatment system, filter plate 6 uses centrifugal force to separate impurities and collect them into collection box 811. After treatment, the user can easily remove collection box 811 by pulling handle 812 and clean the impurities inside. Compared with the traditional method that requires cleaning or replacing filter plates, this design simplifies the operation process, reduces maintenance costs, and thus improves the practicality and economy of the equipment.

[0039] Example 4 is a detailed description based on the above examples, which can be found in the following reference. Figures 1 to 8 The specific method is as follows: In the dyeing and printing wastewater treatment process, reactants are gradually added to funnel 52. The start of motor 3 causes rotating rod 4 and stirring rod 42 to work together, achieving deep mixing of reactants and wastewater. The rotation of rotating rod 4 also drives disc 5, using centrifugal force to evenly disperse the reactants into the dyeing and printing wastewater through the circular holes 53 at the bottom of disc 5, thereby improving the efficiency of reactant addition. The annular trough 54 ensures that all added reactants completely enter the inner cavity 2, preventing resource waste. After the reaction is complete, by controlling the first solenoid valve 121 and the second solenoid valve 131, the wastewater is guided through filter plate 6 for filtration, effectively removing impurities such as flocculent material. The filtered wastewater is then poured into a pre-prepared storage tank. This continuous operation significantly improves the efficiency of dyeing and printing wastewater treatment.

[0040] Furthermore, the connection design between the telescopic rod 61 and the rotating rod 4 allows the filter plate 6 to rotate under the drive of the rotating rod 4, generating centrifugal force to throw out flocculent matter and impurities on the filter plate 6, preventing clogging and ensuring smooth flow of waste liquid. The rotation of the disc 5 periodically squeezes the transmission rod 7 through the groove 55 at its bottom. This action, through the cooperation of the outer ring 71 and the spring 72, causes the transmission rod 7 to vibrate, which in turn drives the mounting plate 8 and the filter plate 6 to vibrate, further loosening residual impurities on the filter plate. Together with centrifugal force, this effectively removes impurities from the filter plate 6, ensuring its unobstructed flow and improving the filtration efficiency of the dyeing and printing waste liquid.

[0041] After processing, the impurities spun off from the filter plate 6 by centrifugal force are collected in the collection box 811. The user can easily remove the collection box 811 and clean out the impurities simply by pulling the handle 812. This design avoids the cumbersome process of traditional cleaning or replacing filter plates, simplifies operation, reduces maintenance costs, and enhances the practicality and economic efficiency of the equipment. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
