Description

Technical Field

[0001] This utility model relates to the field of pigment wastewater treatment technology, specifically to an adsorption device for treating pigment ink wastewater. Background Technology

[0002] Pigment wastewater mainly originates from wastewater generated during the industrial production processes of dyes, coatings, and inks. It contains large amounts of organic matter, heavy metals, and toxic substances, posing a serious threat to the environment and human health. With the rapid development of industry, the discharge of pigment wastewater is constantly increasing, and its impact on the environment is also growing. Therefore, effective treatment technologies are needed to reduce its harm to the environment. Pigment wastewater treatment is an important part of environmental protection, and it is of great significance for protecting water resources, maintaining ecological balance, and protecting human health. Effective pigment wastewater treatment technologies can reduce pollutant emissions, reduce environmental damage, and also help promote sustainable industrial development and green transformation.

[0003] In the field of pigment wastewater treatment, directly adding powdered activated carbon and stirring is a common operation method. However, this method has significant drawbacks. Powdered activated carbon is prone to agglomeration and is difficult to disperse evenly in wastewater. This non-uniformity directly leads to insufficient contact between activated carbon and the target pollutant pigment molecules, thus seriously affecting the overall adsorption efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an adsorption device for treating pigment ink wastewater, so as to solve the problem that insufficient contact between activated carbon powder and pigment wastewater affects the adsorption efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adsorption device for treating pigment ink wastewater, comprising a tank, a feeding mechanism inside the tank, a mixing mechanism on the left side of the tank, a support frame connected to the outer surface of the tank, and a filtering mechanism below the support frame;

[0006] The mixing mechanism includes a water pump, the input end of which is connected to a water storage tank, and the output end of which is connected to a connecting pipe. The end of the connecting pipe away from the water pump is connected to a water jet injector. The outer surface of the water jet injector is connected to a feed pipe, and a solenoid valve is installed on the outer surface of the feed pipe. The end of the feed pipe away from the water jet injector is connected to a material storage tank. A third motor is installed on the back of the material storage tank. The output end of the third motor passes through the material storage tank and is connected to an auger. The output end of the water jet injector is connected to a rotary joint.

[0007] Preferably, the feeding mechanism includes a first motor installed on the left side of the tank body. The output end of the first motor passes through the tank body and is connected to a gear A. The end of the gear A away from the first motor is rotatably connected to a first fixed plate. The first fixed plate and the inner wall of the tank body are rotatably connected to a gear B. The outer surfaces of the gear A and the gear B are meshed with a synchronous belt.

[0008] Preferably, the inner wall of gear B is equipped with a connecting pipe, the right end of which passes through the tank and the first fixed plate in sequence and is connected to a crossbeam. The outer surface of the crossbeam is connected to two feed rods, and the outer surface of each feed rod is connected to multiple nozzles. The left end of the connecting pipe is rotatably connected to the end of the rotary joint away from the water jet.

[0009] Preferably, a second motor is installed on the left side of the crossbeam, and a brush rod is installed at the output end of the second motor after passing through the crossbeam.

[0010] Preferably, the filtration mechanism includes a water outlet pipe connected to the outer surface of the tank body, the end of the water outlet pipe away from the tank body being connected to a filter box, and multiple sets of second fixing plates installed on the inner wall of the filter box, wherein a set of springs is connected to the lower surface of three sets of second fixing plates, and a limit plate is connected to the end of each set of springs away from the second fixing plate, and a filter plate is connected to the lower surface of each limit plate and the three sets of second fixing plates.

[0011] Preferably, the filter box has a door hinged to the front and a water outlet connected to the back.

[0012] Preferably, a fourth motor is installed on the right side of the tank, the output end of the fourth motor passes through the tank and is connected to a stirring frame, a support frame is connected to the outer surface of the tank, and a water inlet is connected to the right side of the tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention uses a water pump to provide power and a water jet to generate negative pressure to precisely draw in the adsorbent, ensuring that the adsorbent is evenly distributed after mixing. This avoids the agglomeration phenomenon that easily occurs with adsorbents such as activated carbon powder. The first motor drives the crossbeam and the feed rod to rotate, so that the mixed slurry is dynamically sprayed through the nozzle in the feeding mechanism. This greatly increases the surface area of ​​contact between the adsorbent and the wastewater. Because the adsorbent can be evenly dispersed and fully contacted with the wastewater, the chance of pigment molecules being adsorbed is greatly increased, thereby significantly improving the adsorption efficiency and treatment effect of the entire wastewater treatment process.

The water jet injector 404 uses the negative pressure generated by the high-speed water flow to feed the adsorbent through the feed pipe 407, which is controlled by the solenoid valve 406, so as to realize the on-demand supply of adsorbent and draw the adsorbent into the storage tank 405 to achieve timely and uniform mixing. The mixed slurry is then pumped to the tank 1.

[0024] like Figure 1 , Figure 2 and Figure 4As shown, a feeding mechanism 2 is provided inside the tank body 1. The feeding mechanism 2 includes a first motor 201 installed on the left side of the tank body 1. The output end of the first motor 201 passes through the tank body 1 and is connected to a gear A 202. The end of gear A away from the first motor 201 is rotatably connected to a first fixed plate 206. The first fixed plate 206 and the inner wall of the tank body 1 are rotatably connected to a gear B 203.

The door 308 on the front of the filter box 302 is convenient for operators to open regularly, remove and clean or replace the clogged filter plate 306 to restore the filtration performance.

[0026] Working principle: The device is supplied with water by a water storage tank 401. A water pump 402 draws water and sends it to a water jet injector 404 via a connecting pipe 403. The water jet injector 404 uses the negative pressure generated by the high-speed water flow to supply adsorbent to the storage tank 405 through a feed pipe 407, which is controlled by a solenoid valve 406. This ensures timely and uniform mixing. The mixed slurry is then pumped to the tank 1. The first motor 201 drives the gear A202 to rotate, allowing the adsorbent to pass through... The synchronous belt 204 drives the gear B203 to rotate. The rotation of the gear B203 affects the fluid in the tank through the connecting pipe 205. The mixed slurry is sprayed out from the nozzle 209 through the connecting pipe 205, the crossbeam 207, and the feed rod 208. The first motor 201 drives the gear B203 to rotate, which in turn drives the crossbeam 207 and the feed rod 208 to rotate, realizing the dynamic spraying of the slurry. The second motor 211 drives the brush rod 210 to rotate, which physically cleans and agitates the inner wall of the tank 1.
