[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] A textile printing and dyeing wastewater purification device includes a pretreatment mechanism 1, and a filter mechanism 2 is fixedly connected to the right side of the pretreatment mechanism 1.

[0028] The pretreatment mechanism 1 includes a filter box 101, four filter plates 102, a pressure pump 103, a drain pipe 104, a regulating tank 105, a filter screen tank 106, a connecting cover 107, a servo motor 108, a connecting shaft 109, a connecting rod 110, a stirring blade 111, a feeding pipe 112, a solenoid valve 113, a storage tank 114, a first one-way valve 115, and a connecting pipe 116. The filter plates 102 are snapped into the inside of the filter box 101, and the pressure pump 103... 03 is fixedly connected to the bottom right side of the filter box 101, the left side of the pressure pump 103 is fixedly connected to the bottom left side of the filter box 101, the drain pipe 104 is fixedly connected to the right side of the pressure pump 103, the regulating tank 105 is located on the right side of the filter box 101, the filter screen tank 106 is snapped into the inside of the regulating tank 105, the connecting cover 107 is snapped into the top of the filter screen tank 106, and the right side of the drain pipe 104 is fixedly connected to the left side of the top of the connecting cover 107.

[0029] In this embodiment: a filter box 101 is set up to initially collect textile dyeing wastewater, facilitating subsequent filtration operations. Simultaneously, filter plates 102 can be snapped into place inside the filter box 101, forming a multi-stage filtration structure. This effectively intercepts larger suspended solids, fiber impurities, and fabric scraps in the wastewater, reducing the solid impurity content and lessening the burden on subsequent treatment equipment, preventing pipe blockage. A booster pump 103 extracts the pre-filtered wastewater from the filter box 101 and pressurizes it to the subsequent regulating tank 105. A drain pipe 104 transfers wastewater from the filter box 101 to the regulating tank 105. The 5-channel design ensures that wastewater can smoothly enter the regulating tank 105 from the filter box 101. The regulating tank 105 has a support frame welded to its surface and is located on the right side of the filter box 101, providing a space for wastewater quality adjustment. It allows for pH adjustment and the addition of chemicals to the pre-filtered wastewater, ensuring the wastewater meets the requirements of subsequent treatment processes and improving the effectiveness and stability of subsequent treatment. The filter screen tank 106 further filters impurities from the wastewater and provides a relatively enclosed space for stirring, allowing for more thorough mixing of chemicals and wastewater, thus improving the water quality adjustment effect. The connecting cover 107 allows access to the servo motor 108 and the feeding pipe 112. The servo motor 108 provides power for the stirring operation in the regulating tank 105, enabling the added reagents and wastewater to mix quickly and evenly. The connecting shaft 109 connects the output end of the servo motor 108 to the connecting rod 110, transmitting the power of the servo motor 108 to the connecting rod 110. Driven by the connecting shaft 109, the connecting rod 110 causes the stirring blades 111 to rotate stably, thoroughly stirring the wastewater in the regulating tank 105. The rotation of the stirring blades 111 agitates the wastewater and reagents in the regulating tank 105, increasing their contact area, accelerating the reaction speed, and making the water quality regulation more thorough and uniform. The feeding pipe 112... This is a channel for adding chemicals into the regulating tank 105, facilitating accurate entry of chemicals into the regulating tank 105 for mixing with wastewater. The solenoid valve 113 can control the amount and time of chemical addition according to the instructions of the PLC controller 203, realizing automated operation, improving the accuracy and controllability of chemical addition, and avoiding chemical waste or insufficient addition. The storage tank 114 is used to store chemicals, ensuring sufficient chemical supply to meet the chemical demand in the wastewater pretreatment process. The first one-way valve 115 only allows wastewater to flow from the regulating tank 105 to the connecting pipe 116 to prevent wastewater backflow. The connecting pipe 116 transports the pretreated and water quality regulated wastewater to the filtration mechanism 2.

[0030] Specifically, such as Figure 2 , Figure 3 , Figure 4As shown, the servo motor 108 is mounted on the top of the connecting cover 107. The output end of the servo motor 108 extends through and to the bottom of the connecting cover 107. The top of the connecting shaft 109 is fixedly connected to the output end of the servo motor 108. The connecting rod 110 is connected to the bottom of the connecting shaft 109 by a flat key. The stirring blade 111 is welded to the surface of the connecting rod 110. The feeding pipe 112 is fixedly connected to the right side of the top of the connecting cover 107. The solenoid valve 113 is mounted on the top of the feeding pipe 112. The storage tank 114 is fixedly connected to the top of the solenoid valve 113. The first one-way valve 115 is mounted on the bottom of the regulating tank 105. The left side of the connecting pipe 116 is fixedly connected to the bottom of the one-way valve. The right side of the connecting pipe 116 is fixedly connected to the top of the left side of the filter mechanism 2.

[0031] Specifically, such as Figure 5 , Figure 6 As shown, the filtration mechanism 2 includes a limit box 201, two filter boxes 202, a PLC controller 203, a guide pipe 204, a second one-way valve 205, an inlet pipe 206, a disinfection box 207, an ultraviolet disinfection lamp 208, a third one-way valve 209, and an outlet pipe 210. The limit box 201 is fixedly connected to the right side of the connecting pipe 116.

[0032] Specifically, such as Figure 5 , Figure 6 As shown, the filter box 202 is slidably connected to the top and bottom of the inner side of the limit box 201, the PLC controller 203 is installed on the top right side of the limit box 201, the guide pipe 204 is fixedly connected to the bottom right side of the limit box 201, and the second one-way valve 205 is installed on the right side of the guide pipe 204.

[0033] In this embodiment: By setting a limiting box 201 to provide installation and limiting space for the internal filter box 202, the filter box 202 can be stably installed in the limiting box 201. The bottom of the filter box 202 is set as a filter mesh, the inner side of the top filter box 202 is filled with activated carbon particles, and the inside of the bottom filter box 202 is filled with fiber balls, forming a double filtration structure, which can further remove fine impurities, colloids, and some organic matter in wastewater, improve the quality of effluent, and the sliding connection method makes it easy for operators to remove the filter box 202 for cleaning, replacement of filter media and other maintenance operations. The PLC controller 203 can control the pressure pump 103, servo motor 108, solenoid valve 113, first one-way valve 115, second one-way valve 205, third one-way valve 209 and ultraviolet disinfection lamp 208. The guide pipe 204 is used to discharge the filtered wastewater, allowing it to smoothly enter subsequent disinfection and other treatment steps. The second one-way valve 205 only allows the filtered wastewater to flow from the limit box 201 to the inlet pipe 206, preventing wastewater from flowing back into the limit box 201. The inlet pipe 206 can transport the filtered wastewater to the disinfection box 207. The disinfection box 207 provides a place for the disinfection treatment of wastewater and can also support and limit the ultraviolet disinfection lamp 208. The ultraviolet disinfection lamp 208 uses the bactericidal effect of ultraviolet light to destroy the DNA structure of microorganisms, achieving the purpose of disinfection. The third one-way valve 209 only allows the disinfected water to flow from the disinfection box 207 to the outlet pipe 210, preventing the disinfected water from flowing back into the disinfection box 207. The outlet pipe 210 discharges the disinfected wastewater.

[0034] Specifically, such as Figure 5 , Figure 6 As shown, the inlet pipe 206 is fixedly connected to the right side of the second single-way valve 205, the disinfection box 207 is fixedly connected to the right side of the inlet pipe 206, the ultraviolet disinfection lamp 208 is installed inside the disinfection box 207, the third single-way valve 209 is installed at the bottom right side of the disinfection box 207, and the outlet pipe 210 is fixedly connected to the right side of the third single-way valve 209.

[0035] Specifically, such as Figure 4 As shown, the top of the storage tank 114 is fitted with a tank lid 3, and the surface of the tank lid 3 is engraved with anti-slip texture.

[0036] In this embodiment: by setting the lid 3, it is convenient for staff to open and close the storage tank 114 and to add medicine. By setting the anti-slip texture, the friction can be increased to prevent the lid 3 from slipping off during operation.

[0037] Specifically, such as Figure 2 As shown, a reinforcing base 4 is fixedly connected to the bottom of the pressure pump 103, and the surface of the reinforcing base 4 is coated with an anti-corrosion coating.

[0038] Specifically, such as Figure 1As shown, a handle 5 is fixedly connected to the front side of the filter box 202, and the surface of the handle 5 is engraved with anti-slip texture.

[0039] In this embodiment: by setting the reinforcing base 4, the stability of the booster pump 103 can be increased, preventing it from shifting or tilting due to vibration or other reasons during operation. By setting the anti-corrosion coating, the reinforcing base 4 can be protected from corrosion by wastewater, extending its service life. By setting the handle 5, it is convenient for staff to take out and install the filter box 202 for cleaning, replacement of filter media and other maintenance operations. By setting the anti-slip texture, the friction can be increased, making the operation more convenient and safer, and improving work efficiency.

[0040] Working principle: First, the user pours the wastewater to be treated into the filter box 101 from the top. The wastewater flows through four filter plates 102 in sequence within the filter box 101. The filter plates 102 intercept larger suspended solids, fibrous impurities, and solid pollutants such as rag scraps in the wastewater. After preliminary filtration, the user issues a command through the PLC controller 203 to start the pressure pump 103. The pressure pump 103 then starts working, extracting the pre-filtered wastewater from the filter box 101 and transporting it to the regulating tank 105 via the guide pipe 204. At this time, the user again uses the PLC controller 203 to simultaneously open the solenoid valve 113 and the servo motor 1 08. After the solenoid valve 113 is opened, the reagent in the storage tank 114 will fall into the regulating tank 105 through the feeding pipe 112. At the same time, the servo motor 108 starts to run, driving the connecting shaft 109 and the connecting rod 110 to rotate synchronously. As the connecting rod 110 rotates, the stirring blade 111 also rotates, quickly and thoroughly mixing the reagent and wastewater falling into the regulating tank 105, accelerating the chemical reaction. After a sufficient period of stirring and mixing, the user opens the first one-way valve 115 through the PLC controller 203. At this time, the uniformly mixed waste liquid in the regulating tank 105 flows into the limit box 201 through the connecting pipe 116 under the action of gravity. The wastewater flows downwards from the top of the limiting box 201. During this process, the mixed wastewater first comes into full contact with the activated carbon particles in the top filter box 202. The activated carbon particles adsorb organic pollutants and pigments in the wastewater. Subsequently, the wastewater flows downwards into the bottom filter box 202 through the filter screen at the bottom of the top filter box 202. In the bottom filter box 202, the wastewater treated by activated carbon adsorption comes into contact with fiber balls, which further purify the wastewater, removing residual fine impurities and some harmful substances. After being treated by these two layers of filter boxes 202, the purified wastewater leaks to the bottom of the limiting box 201. Next, the user controls the PLC... The controller 203 opens the second one-way valve 205. After the second one-way valve 205 is opened, the wastewater at the bottom of the limit box 201 flows into the disinfection box 207 through the guide pipe 204 and the inlet pipe 206. The user then uses the PLC controller 203 to turn on the ultraviolet disinfection lamp 208 and sets the disinfection time according to actual needs. When the user-set disinfection time is reached, the PLC controller 203 automatically controls the third one-way valve 209 to open. At this time, the purified and disinfected water is discharged from the disinfection box 207 through the outlet pipe 210. Finally, the user can use an external collection device to collect the purified water and treat it centrally.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
