[0029] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0030] Please combine Figure 1-6 The assembled printing and dyeing wastewater treatment unit of this embodiment includes a recovery box 1, a cleaning assembly 2 is provided on the upper surface of the recovery box 1, a reaction box 3 is fixedly connected to the middle of the upper surface of the recovery box 1, an assembly base 4 is fixedly connected to the upper surface of the reaction box 3, a pretreatment tank 5 is clamped inside the assembly base 4, and a grid plate 6 is fixedly connected to the inside of the pretreatment tank 5;

[0031] The cleaning assembly 2 includes a first water pump 201, which is fixedly installed on the upper surface of the recovery box 1 by bolts. The input end of the first water pump 201 is fixedly connected to a first water inlet pipe 202, and the first water inlet pipe 202 is arranged inside the recovery box 1. The output end of the first water pump 201 is fixedly connected to a first water outlet pipe 203, and the other end of the first water outlet pipe 203 is fixedly connected to a nozzle pipe 204. The outer surface of the nozzle pipe 204 is fixedly connected to a plurality of high-pressure nozzles 205. Both ends of the nozzle pipe 204 are fixedly connected to a pipe bracket 206, and the pipe bracket 206 is fixedly connected to the surface of the assembly base 4. The treated printing and dyeing wastewater is first collected in the recycling box 1, then extracted by the first water pump 201, and enters the cleaning component 2 through the first water inlet pipe 202. The wastewater is transported to the nozzle pipe 204 through the first outlet pipe 203 and sprayed out through the high-pressure nozzle 205 to comprehensively clean the grid plate 6. Under the action of high-pressure water, the impurities remaining on the grid plate 6 and the dirt in the gaps are completely washed away to ensure that it maintains good filtering performance. During the cleaning process, the water flow containing impurities will enter the purification system again for treatment, thereby effectively removing pollutants and ensuring the efficiency of wastewater treatment and the cleanliness of the equipment.

[0032] Auxiliary handles 7 are fixedly connected to both sides of the outer surface of the pretreatment tank 5, and circulation holes 8 are provided on the surfaces of the reaction box 3, the assembly base 4 and the pretreatment tank 5. The upper surface of the reaction box 3 is provided with an addition port 9. The pretreated wastewater flows into the reaction box 3 through the circulation hole 8. In this process, the wastewater and the chemical agents added from the addition port 9 are fully mixed, a chemical reaction occurs, and the pollutants are further removed. In the reaction box 3, the suspended matter and pollutants in the wastewater form precipitation under the action of the chemical agents.

[0033] The outer surface of the reaction box 3 is fixedly connected to a diagonal support plate 10, and a servo motor 11 is fixedly installed on the upper surface of the diagonal support plate 10 by bolts. The output end of the servo motor 11 is fixedly connected to a transmission shaft 12, and the outer surface of the transmission shaft 12 is fixedly connected to a plurality of stirring blades 13. The servo motor 11 drives the stirring blades 13 to rotate through the transmission shaft 12, and fully stirs the wastewater and chemical agents in the reaction box 3, so that the agents and pollutants in the wastewater are fully in contact and reacted. Through the stirring action, the suspended matter and pollutants in the wastewater are prompted to form larger particles, which is convenient for the subsequent precipitation and separation process.

[0034] A second water pump 14 is fixedly installed on the upper surface of the recovery box 1 by bolts. The input end of the second water pump 14 is fixedly connected to a second water inlet pipe 15 , and the output end of the second water pump 14 is fixedly connected to a second water outlet pipe 16 .

[0035] The second water inlet pipe 15 is arranged inside the reaction box 3, and the second water outlet pipe 16 is arranged inside the recovery box 1. The wastewater treated by the reaction box 3, the suspended matter and pollutants therein form precipitation under the action of chemical agents, and the precipitation is deposited at the bottom of the reaction box 3. The second water inlet pipe 15 extracts the upper layer of clear water after the precipitation separation and sends it back to the recovery box 1 for re-filtration and purification.

[0036] The outer surface of the reaction box 3 is fixedly connected to the main control panel 17, and the inner wall of the recovery box 1 is provided with a first chute 18. The interior of the first chute 18 is slidably connected to the first pull-out box 19. The interior of the first pull-out box 19 is provided with a primary filter 20. When the wastewater after solid-liquid separation after precipitation enters the recovery box 1, it first passes through the primary filter 20. Large particles of impurities are intercepted on the surface of the filter, and cleaner water enters the recovery box 1 through the filter. The sliding connection design of the first chute 18 and the first pull-out box 19 makes it easy to pull out and push back the primary filter 20, which is convenient for regular cleaning and replacement of the filter to ensure the filtering effect.

[0037] A second chute 21 is provided on the inner wall of the recycling box 1, and a second pull-out box 22 is slidably connected inside the second chute 21. A secondary filter screen 23 is provided inside the second pull-out box 22. The outer surfaces of the first pull-out box 19 and the second pull-out box 22 are fixedly connected with a handle 24. After the waste water enters the recycling box 1, it is first preliminarily filtered through the primary filter screen 20 to remove large particles of impurities, and then further filtered through the secondary filter screen 23 to remove smaller particles of impurities and improve water quality. The sliding connection design of the second chute 21 and the second pull-out box 22 makes it easy to pull out and push back the secondary filter screen 23, which is convenient for regular cleaning and replacement of the filter screen to ensure the filtering effect.

[0038] The implementation principle of the assembled printing and dyeing wastewater treatment unit in the embodiment of the present application is as follows: the personnel first put the printing and dyeing wastewater into the pretreatment tank 5, and perform preliminary filtration through the grid plate 6 to remove large particles of impurities. The pretreated wastewater flows into the reaction box 3 through the flow hole 8. The operator puts in chemical agents through the addition port 9, and then the servo motor 11 drives the stirring blade 13 to rotate, so as to promote the full mixing of the wastewater and the agent, accelerate the chemical reaction, and cause the suspended matter and pollutants to form precipitation. The suspended matter in the wastewater forms precipitation under the action of the chemical agent, and the precipitation is deposited at the bottom of the reaction box 3. The second water inlet pipe 15 draws the unprecipitated water to the second water pump 14, and then sends it back to the recovery box 1 through the second water outlet pipe 16. The wastewater in the recovery box 1 passes through the first water pump 16. The pump 201 extracts the water, passes through the first water inlet pipe 202 and the first water outlet pipe 203, and is finally sprayed out from the high-pressure nozzle 205 to perform high-pressure cleaning on the grid plate 6. The cleaned impurity-containing water enters the pretreatment tank 5 again for treatment. The wastewater is initially filtered through the primary filter 20 in the first pull-out box 19 to remove large particles of impurities, and then deeply filtered through the secondary filter 23 in the second pull-out box 22 to remove finer impurities and improve water quality. The main control panel 17 monitors the entire wastewater treatment process to ensure stable operation of the system. The sliding design of the first chute 18 and the second chute 21 makes it convenient to clean and replace the primary filter 20 and the secondary filter 23, which are operated by the handle 24 to ensure filtration efficiency.
