Description

Technical Field

[0001] The utility model relates to a sedimentation device, in particular to a sedimentation device for treating printing and dyeing wastewater, belonging to the technical field of printing and dyeing wastewater sedimentation. Background Art

[0002] Printing and dyeing wastewater refers to wastewater generated during the dyeing and printing process of textiles. This wastewater contains a variety of complex chemical substances and pollutants. The suspended matter in the wastewater is mainly fiber scraps and fine textile particles, and the organic matter includes unreacted dyes, cellulose and pulp. Treatment of this wastewater requires the use of sedimentation, filtration, adsorption and biological treatment methods to meet environmental emission standards.

[0003] A printing and dyeing wastewater sedimentation device disclosed in Chinese patent disclosure specification CN218900941U introduces printing and dyeing wastewater through a set feed port, and the printing and dyeing wastewater falls on the upper surface of the guide plate and flows along the guide plate to the guide frame. In this way, the water baffle drives the rotating rod to rotate, which has a buffering effect on the water flow, preventing the water flow from directly falling into the sedimentation frame and causing the sediment at the bottom to float up, thereby improving the sedimentation effect of the sedimentation frame.

[0004] The above device buffers the water flow through the guide plate and the guide frame, thereby improving the sedimentation effect of the sedimentation frame. In actual application, it is found that after long-term use, the sediment will accumulate at the bottom of the sedimentation frame, which is not convenient for subsequent cleaning. At the same time, the temperature of the printing and dyeing wastewater is usually high when it is just treated. The high temperature will cause the flocculant to react prematurely, thereby affecting the flocculation effect. To this end, we provide a sedimentation device for the treatment of printing and dyeing wastewater. Utility Model Content

[0028] See also Figure 1 to Figure 4 The embodiment of the utility model provides a sedimentation device for treating printing and dyeing wastewater, including a sedimentation tank 1, the sedimentation tank 1 includes a tank body 101, one side of the tank body 101 is connected with a water inlet pipe 102, the bottom of the tank body 101 is connected with a sewage pipe 103, the sewage after cleaning the sediment at the bottom of the tank body 101 can be discharged through the sewage pipe 103, the other side of the tank body 101 is connected with a water outlet pipe 104, and the water outlet pipe 104 is provided to discharge the water after the sedimentation.

[0029] Please refer to Figure 1 and Figure 4 A cleaning mechanism 2 for cleaning sediment is provided at the bottom of the pool body 101. The cleaning mechanism 2 includes a water pump 201. The input end of the water pump 201 is connected to an external water source. Starting the water pump 201 can pump the external water source into the water pump 201. The output end of the water pump 201 is connected to a shell 202 evenly distributed at the bottom of the pool body 101 through a pipeline. The shell 202 is provided with a water inlet 203, a first chamber 204, and a second chamber 205 in sequence. A second sealing gasket 213 is fixed to the upper end of the water inlet 203, a first sealing gasket 212 is fixed to the upper end of the first chamber 204, and a first sealing gasket 213 is fixed to the upper end of the first chamber 204. A sealing gasket 212 and a second sealing gasket 213 can improve the sealing effect. The diameter of the second chamber 205 is greater than the diameter of the first chamber 204, so that the movable plate 208 can resist the upper end of the first chamber 204, and the movable plate 208 is limited by the upper end of the first chamber 204. A sealing ball 206 is provided at the water inlet 203, and a connecting column 207 is fixed to the upper end of the sealing ball 206. The diameter of the sealing ball 206 is greater than the inner diameter of the water inlet 203, and then the sealing ball 206 cooperates with the second sealing gasket 213 to resist the upper end of the water inlet 203 to seal the water inlet 203.

[0030] The other end of the connecting column 207 is fixed with a movable plate 208, and a third sealing gasket 214 is fixed on the side of the movable plate 208 away from the connecting column 207. The third sealing gasket 214 is provided to seal the upper end of the shell 202 to prevent water leakage at the connection between the guide column 210 and the shell 202 when water is sprayed through the nozzle 209. A compression spring 215 is fixed on the side of the movable plate 208 close to the first chamber 204. The nozzles 209 are evenly distributed and installed obliquely in the second chamber 205. The end of the movable plate 208 away from the connecting column 207 is fixed with a guide column 210. The guide column 210 penetrates the shell 202. The movable plate 208 is provided with a rubber pad 211 on one end of the guide column 210 away from the movable plate 208. When the movable plate 208 moves, the guide column 210 is also driven to slide on the shell 202, and then the rubber pad 211 is driven to move by the guide column 210. The movable plate 208 can be guided by the guide column 210 and the rubber pad 211, so as to stabilize the movement of the movable plate 208. At the same time, when not being cleaned, the rubber pad 211 is in a state of being against the top of the shell 202, and the rubber pad 211 can also seal the upper end of the shell 202.

[0031] Specifically, the water pumped to the water inlet 203 by the water pump 201 will exert pressure on the sealing ball 206, so that the sealing ball 206 drives the connecting column 207 and the movable plate 208 to move. At the same time, the movable plate 208 will also pull the compression spring 215. When the movable plate 208 moves to the top of the shell 202, water will be sprayed out from the nozzle 209. After the cleaning work is completed, under the action of the elastic force generated by the deformation of the compression spring 215, the movable plate 208 will drive the sealing ball 206 to press against the second sealing gasket 213 through the connecting column 207, thereby sealing the water inlet 203.

[0032] Please refer to Figure 1 and Figure 2 A cooling mechanism 3 for cooling the printing and dyeing wastewater is arranged on the water inlet pipe 102. The cooling mechanism 3 includes a chiller 301. The chiller 301 is an existing device and is a cooling water device that can provide constant temperature, constant flow and constant pressure. The chiller 301 is connected with a cooling pipe 302. The printing and dyeing wastewater inside the cooling box 303 can be cooled through the cooling pipe 302 to avoid the influence of excessive temperature of the printing and dyeing wastewater on the precipitation effect. The water inlet pipe 102 is connected with the cooling box 303. The cooling pipe 302 is fixed on the inner wall of the cooling box 303. The printing and dyeing wastewater in the water inlet pipe 102 is discharged into the cooling box 303 and then discharged into the pool body 101 through the water inlet pipe 102.

[0033] Please refer to Figure 1 and Figure 3 A buffer mechanism 4 is provided at one end of the water inlet pipe 102 extending to the inside of the pool body 101. The buffer mechanism 4 includes a fixing rod 401 fixed to the side of the water inlet pipe 102. A baffle 402 is fixed to the other end of the fixing rod 401. The fixing rod 401 can fix the baffle 402. There is a certain distance between the baffle 402 and the water inlet pipe 102. The printing and dyeing wastewater discharged through the water inlet pipe 102 will be discharged to the baffle 402. The printing and dyeing wastewater discharged from the water inlet pipe 102 is buffered by the baffle 402. Evenly distributed water permeable holes 403 are opened on the side of the baffle 402. The water permeable holes 403 can be used to divert water flow, thereby further improving the buffering effect on the water flow.

[0034] Working principle: First, start the chiller 301, which can circulate cold water inside the cooling pipe 302. Then, the printing and dyeing wastewater with a certain temperature is transported to the cooling box 303 through the water inlet pipe 102. The printing and dyeing wastewater is cooled by the cold water inside the cooling pipe 302 to avoid the influence of too high temperature of the printing and dyeing wastewater on the precipitation effect.

[0035] When it is necessary to clean the sediment at the bottom of the pool body 101, first, the water pump 201 can transport water through the pipeline to the water inlet 203, and the water flow will exert pressure on the sealing ball 206, so that the sealing ball 206 pulls the compression spring 215 through the connecting column 207 and the movable plate 208 until the movable plate 208 rests against the inner top wall of the shell 202. The water flow will be sprayed out through the inclined nozzle 209, and the sediment at the bottom of the pool body 101 is cleaned through the nozzles 209 evenly distributed on the multiple shells 202. Finally, the sewage can be discharged through the sewage pipe 103.
