Description

Technical Field

[0001] The invention relates to the technical field of recycling and treating waste liquid in printing and dyeing, and in particular to a device for recycling and treating waste liquid in cloth printing and dyeing. Background Art

[0002] In the textile industry, printing and dyeing wastewater mainly comes from the wastewater generated in the pretreatment, dyeing, printing and finishing processes of cotton, wool, linen, silk, chemical fiber or blended products. These wastewaters contain a large amount of dyes, slurries and other complex chemical components, which cause serious pollution to the environment. With the improvement of environmental awareness and the strictness of wastewater discharge standards, the treatment and recycling of printing and dyeing wastewater has become particularly important.

[0003] The process of treating printing and dyeing waste liquid usually involves a series of chemical reactions and physical filtration steps. At present, there are some efficiency problems in the addition of reactants to waste liquid treatment facilities. For example, after the reactants are added to the waste liquid at one time, they fail to fully mix with the waste liquid and sink to the bottom, which affects the thoroughness of the reaction. In addition, the filter plates used for a long time are prone to clogging and need to be manually cleaned and replaced, which not only increases maintenance costs but also affects treatment efficiency. Summary of the invention

[0014] 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;

[0015] Among them, 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 body, and the transmission rod is clamped with the groove.

[0016] Preferably, partitions are fixedly connected to the interior of the installation plate, and the partitions are arranged in four groups, and the four groups of partitions form installation cavities, and each group of installation cavities is designed to correspond one to one with each group of notches.

[0017] Preferably, a collection box is adapted to be installed inside the installation cavity, a handle is fixedly connected to the outside of the collection box, and the collection boxes are arranged in four groups in total.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the process of treating printing and dyeing waste liquid, the reactants are gradually added to the funnel, and the motor is used to drive the rotating rod and the stirring rod for stirring to ensure that the reactants and the wastewater are fully mixed. At the same time, the rotating rod drives the disc to generate centrifugal force, and the reactants are quickly dispersed into the printing and dyeing waste liquid through the circular hole at the bottom of the disc, thereby improving the addition efficiency. The design of the annular groove ensures that all reactants can fall into the inner cavity to avoid waste. After the reaction is completed, the waste liquid is controlled by the first solenoid valve and the second solenoid valve to flow through the filter plate for filtration to remove impurities, and finally the filtered waste liquid is discharged into the storage tank. This process not only improves the addition efficiency of the reactants, but also improves the overall treatment efficiency of printing and dyeing wastewater.

[0020] 2. In the system for treating printing and dyeing waste liquid, the telescopic rod is connected to the rotating rod, so that the rotation of the rotating rod can drive the filter plate to rotate, generate centrifugal force, and throw away the floccules and impurities on the surface of the filter plate to prevent the filter plate from being blocked and ensure the smooth flow of waste liquid. At the same time, the rotation of the disc intermittently squeezes the transmission rod through the groove at its bottom. This action causes the transmission rod to vibrate through the cooperation of the outer ring and the spring, thereby driving the mounting disc and the filter plate to vibrate. The vibration effect helps to loosen the residual impurities on the filter plate, and combined with the centrifugal force generated by the rotation, effectively removes the impurities on the surface of the filter plate, ensuring the unobstructed flow of the filter plate, thereby achieving efficient filtration and circulation of printing and dyeing waste liquid.

[0021] 3. In the printing and dyeing waste liquid treatment system, the filter plate uses centrifugal force to throw away impurities and collect them in the collection box. After the treatment is completed, the user can easily take out the collection box by pulling the handle and clean the impurities in it. Compared with the traditional method of cleaning or replacing the filter plate, this design simplifies the operation process and reduces maintenance costs, thereby improving the practicality and economy of the equipment.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1;

[0033] See also Figures 1 to 6 The present invention provides a technical solution: a waste liquid recovery and treatment device in fabric printing and dyeing, comprising a tank body 1, an inner cavity 2 opened inside the tank body 1, and a motor 3 adapted to be installed on the top of the tank body 1, the output end of the motor 3 is fixedly connected to a rotating rod 4, the outer side of the rotating rod 4 is fixedly connected to a disc 5, the bottom end of the rotating rod 4 is provided with a filter plate 6, the inside of the tank body 1 is slidably connected to a transmission rod 7, and the bottom end of the transmission rod 7 is fixedly connected to a mounting plate 8;

[0034] The filter plate 6 is rotatably connected to the inside of the mounting plate 8, the top end of the transmission rod 7 is configured to be hemispherical, and the bottom end of the inner cavity 2 is configured to be in an inverted cone.

[0035] Furthermore, a support leg 11 is fixedly connected to the bottom end of the tank body 1 , a notch 12 is provided on the outer side of the tank body 1 , and the notch 12 is arranged in four groups. A drain pipe 13 is fixedly connected to the bottom end of the tank body 1 .

[0036] Furthermore, a support leg 11 is fixedly connected to the bottom end of the tank body 1 , a notch 12 is provided on the outer side of the tank body 1 , and the notch 12 is arranged in four groups. A drain pipe 13 is fixedly connected to the bottom end of the tank body 1 .

[0037] Furthermore, a mounting frame 31 is provided at the top of the tank body 1 , and bolts 32 are threadedly connected to both sides of the mounting frame 31 . The mounting frame 31 is installed at the top of the tank body 1 through the bolts 32 , and the motor 3 is adapted to be installed at the top of the mounting frame 31 .

[0038] Furthermore, a mounting 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 mounting sleeve 41. The stirring rods 42 are arranged in at least five groups, and the number of the stirring rods 42 in each group is four, and the stirring rods 42 are located inside the inner cavity 2.

[0039] 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;

[0040] The connecting pipe 51 is rotatably connected to the tank body 1 .

[0041] When the printing and dyeing wastewater needs to be recycled, the wastewater is first added to the inner cavity 2 through the funnel 52, and then the reactants are added to the funnel 52. At this time, the reactants will accumulate inside the connecting tube 51 and the funnel 52, and slowly diffuse into the inside of the disc 5, and finally fall into the inner cavity 2 through the circular hole 53 at the bottom of the disc 5, and react with the printing and dyeing wastewater.

[0042] After the reactants are added to the interior of the funnel 52, the motor 3 is started. The operation of the motor 3 drives the rotating rod 4 at the output end of the motor 3 to rotate, and the rotating rod 4 drives the stirring rod 42 fixed on the outside thereof. The rotating stirring rod 42 stirs the reactants and wastewater that slowly fall into the inner cavity 2. Compared with the traditional method of adding reactants all at once, the gradual addition method can enable the reactants to come into more comprehensive contact with the printing and dyeing wastewater when entering the printing and dyeing wastewater, so that the two can react fully.

[0043] At the same time, the rotating rod 4 will also drive the disc 5 fixed on its outer side to rotate, and the rotating disc will generate centrifugal force. Under the action of centrifugal force, the reactants inside the connecting tube 51 can be quickly scattered inside the disc 5 and fall into the printing and dyeing waste liquid through the circular hole 53 at the bottom of the disc 5, thereby improving the efficiency of adding reactants, and further improving the overall treatment efficiency of printing and dyeing waste water. In addition, since the reactants falling into the printing and dyeing waste liquid through the circular hole are independent, it can be ensured that each reactant can fully contact with the printing and dyeing waste liquid, ensuring that the two can fully react.

[0044] With the design of the annular groove 54, even if the reactant does not fall through the circular hole 53 due to the centrifugal force, it 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 recovery and treatment of printing and dyeing waste liquid.

[0045] When the printing and dyeing waste liquid and the reactant have fully reacted, the first solenoid valve 121 and the second solenoid valve 131 are opened by the upper computer. At this time, the printing and dyeing waste liquid in the inner cavity 2 will flow down through the first solenoid valve 121, and the printing and dyeing waste liquid will be filtered under the action of the filter plate 6, thereby filtering out impurities such as floccules produced by the reaction, and the filtered printing and dyeing waste liquid will flow into the pre-prepared storage tank through the drain pipe 13.

[0046] In summary, in the process of treating printing and dyeing waste liquid, by gradually adding the reactants into the funnel 52, the motor 3 is used to drive the rotating rod 4 and the stirring rod 42 to stir, ensuring that the reactants are fully mixed with the wastewater. At the same time, the rotating rod 4 drives the disc 5 to generate centrifugal force, and the reactants are quickly dispersed into the printing and dyeing waste liquid through the circular hole 53 at the bottom of the disc 5, thereby improving the addition efficiency. The design of the annular groove 54 ensures that all reactants can fall into the inner cavity 2 to avoid waste. After the reaction is completed, the first solenoid valve 121 and the second solenoid valve 131 are controlled to make the waste liquid flow through the filter plate 6 for filtration, remove impurities, and finally discharge the filtered waste liquid into the storage tank. This process not only improves the addition efficiency of the reactants, but also improves the overall treatment efficiency of printing and dyeing wastewater.

[0047] Example 2 improves the specific process of pipeline heat treatment based on Example 1. For specific methods, please refer to Figure 1 to Figure 7 ;

[0048] Furthermore, a telescopic rod 61 is fixedly connected to the top end of the filter plate 6 , and the telescopic rod 61 is slidably connected to the bottom end of the rotating rod 4 .

[0049] 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;

[0050] One end of the spring 72 is connected to the bottom end of the outer ring 71 , the other end of the spring 72 is connected to the inside of the tank body 1 , and the transmission rod 7 is engaged with the groove 55 .

[0051] Since the telescopic rod 61 is slidably connected to the bottom end of the rotating rod 4, the rotating 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 the centrifugal force, the flocs and impurities remaining on the surface of the filter plate 6 will be thrown to the outside of the filter plate 6, thereby effectively avoiding clogging of the filter plate 6, thereby ensuring that the printing and dyeing waste liquid can pass through the filter plate smoothly.

[0052] The rotation of the disc 5 will cause the groove 55 at the bottom of the disc 5 to continuously adjust its position, and the disc 5 cooperates with the groove 55 to continuously and intermittently squeeze the transmission rod 7. When squeezing the transmission rod 7, the transmission rod 7 slides down and squeezes the spring 72 through the outer ring 71, causing the spring 72 to contract. If the transmission rod 7 is not squeezed, the transmission rod 7 is reset under the elasticity of the spring 72. Repeating this cycle can drive the installation disk 8 to vibrate through the transmission rod 7, and the installation disk 8 will drive the filter plate 6 to vibrate.

[0053] The vibrating filter plate 6 can loosen the impurities remaining on the surface of the filter plate 6, and the rotating filter plate 6 can effectively shake off the impurities remaining on the surface of the filter plate 6, ensuring the smoothness of the filter plate 6 and achieving smooth circulation of the printing and dyeing waste liquid.

[0054] In summary, in the system for treating printing and dyeing waste liquid, the telescopic rod 61 is connected to the rotating rod 4, so that the rotation of the rotating rod 4 can drive the filter plate 6 to rotate, generate centrifugal force, and throw away the floccules and impurities on the surface of the filter plate 6, prevent the filter plate 6 from being blocked, and ensure the smooth flow of waste liquid. At the same time, the rotation of the disc 5 intermittently squeezes the transmission rod 7 through the groove 55 at its bottom end. This action causes the transmission rod 7 to vibrate through the cooperation of the outer ring 71 and the spring 72, thereby driving the mounting plate 8 and the filter plate 6 to vibrate. The vibration effect helps to loosen the residual impurities on the filter plate, and combined with the centrifugal force generated by the rotation, effectively removes the impurities on the surface of the filter plate 6, ensuring that the filter plate 6 is unobstructed, thereby achieving efficient filtration and circulation of printing and dyeing waste liquid.

[0055] Embodiment 3 is further described in detail based on the above embodiment 2, and can refer to 8. The specific method is as follows:

[0056] Furthermore, the interior of the installation plate 8 is fixedly connected with partitions 81 , and the partitions 81 are arranged in four groups, and the four groups of the partitions 81 form installation cavities, and each group of the installation cavities is designed to correspond one to one with each group of the notches 12 .

[0057] Furthermore, a collection box 811 is adapted to be installed inside the installation cavity, and a handle 812 is fixedly connected to the outer side of the collection box 811. The collection boxes 811 are arranged in four groups.

[0058] The impurities thrown away by the centrifugal force of the filter plate 6 will enter the interior of the collection box 811. When the printing and dyeing waste liquid treatment is completed, the collection box 811 can be taken out by pulling the handle 812, and the impurities inside it can be cleaned. Compared with the traditional method of cleaning or replacing the filter plate, this method is not only simpler and faster in overall operation, but also has lower maintenance costs in the later stage, further improving the overall practicality of the equipment.

[0059] In summary, in the printing and dyeing waste liquid treatment system, the filter plate 6 uses centrifugal force to throw away impurities and collect them in the collection box 811. After the treatment is completed, the user can easily take out the collection box 811 by pulling the handle 812 and clean the impurities therein. Compared with the traditional method of cleaning or replacing the filter plate, this design simplifies the operation process and reduces maintenance costs, thereby improving the practicality and economy of the equipment.

[0060] Embodiment 4, based on the above embodiment, is described in detail as a whole, and can be referred to Figures 1 to 8 , the specific method is as follows:

[0061] In the process of treating printing and dyeing wastewater, the reactants are gradually put into the funnel 52, and the start of the motor 3 enables the rotating rod 4 and the stirring rod 42 to work together to achieve deep mixing of the reactants and the wastewater. The rotation of the rotating rod 4 also drives the disc 5, and the centrifugal force is used to evenly disperse the reactants into the printing and dyeing waste liquid through the circular hole 53 at the bottom of the disc 5, thereby improving the efficiency of adding reactants. The annular groove 54 ensures that all added reactants can fully enter the inner cavity 2, preventing waste of resources. After the reaction is completed, by controlling the first solenoid valve 121 and the second solenoid valve 131, the waste liquid is guided to pass through the filter plate 6 for filtration, effectively removing impurities such as flocs, and pouring the filtered waste liquid into a pre-prepared storage tank. This continuous operation significantly improves the efficiency of printing and dyeing wastewater treatment.

[0062] In addition, 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 the floccules and impurities on the filter plate 6, preventing the filter plate 6 from being blocked and ensuring the smooth flow of the waste liquid. The rotation of the disc 5 periodically squeezes the transmission rod 7 through the groove 55 at the bottom thereof. This action causes the transmission rod 7 to vibrate through the cooperation of the outer ring 71 and the spring 72, thereby driving the mounting disc 8 and the filter plate 6 to vibrate, further loosening the residual impurities on the filter plate, and working together with the centrifugal force, effectively removing the impurities on the filter plate 6, ensuring the smooth flow of the filter plate 6, and improving the filtration efficiency of the printing and dyeing waste liquid.

[0063] After the treatment is completed, the impurities thrown off the filter plate 6 by the centrifugal force are collected in the collection box 811. The user only needs to pull the handle 812 to easily take out the collection box 811 and clean the impurities therein. This design avoids the cumbersome process of traditional cleaning or replacement of the filter plate, simplifies the operation steps, reduces the maintenance cost, and enhances the practicality and economic benefits of the equipment. Although the embodiments of the present invention have been shown and described, it can be understood by those of ordinary skill 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 present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
