Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater treatment technology, specifically to a heavy metal adsorption treatment device for industrial wastewater. Background Technology

[0002] The main function of heavy metal adsorption treatment devices in industrial wastewater is to remove heavy metal ions from wastewater, preventing them from entering water bodies and soil and causing environmental pollution. These devices use specific adsorbents (such as activated carbon and resin) to adsorb heavy metal ions from the wastewater onto their surfaces, thereby achieving heavy metal removal. The adsorbents can be regenerated or replaced to recover the heavy metals, achieving efficient resource utilization.

[0003] Chinese Patent CN217676903U discloses a wastewater heavy metal adsorption treatment device, comprising a tank with connection ports at both ends. A rectangular frame is fixedly installed inside the tank, and a placement frame is slidably connected inside the rectangular frame. By using this placement frame, when the packing needs to be replaced, the operator can pull and rotate the connecting frame to separate the straight rod from the locking block, thus pulling the placement frame out of the rectangular frame. Then, the cover plate is removed, and the packing is taken out of the placement frame for replacement. After replacement, the cover plate is placed on the placement frame, and the placement frame is inserted into the rectangular frame. Then, the connecting frame is pulled and rotated to lock the straight rod into one side of the locking block. The elastic band pulls the slider, causing the straight rod to press the placement frame inward, thus fixing the placement frame in place. This completes the installation of the placement frame. The entire replacement process is simple and convenient for operators.

[0004] However, the above scheme makes it inconvenient to sample and test the wastewater inside the treatment equipment, which makes it impossible for staff to replace the adsorbed material in a timely manner. This can easily lead to incomplete adsorption of heavy metals in industrial wastewater, affecting the secondary use of wastewater and reducing the treatment effect of heavy metal adsorption treatment devices in industrial wastewater.

[0021] 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.

[0022] Example: Figure 1 - Figure 4 As shown, this utility model provides a technical solution for a heavy metal adsorption treatment device for industrial wastewater, including a treatment tank 1. Support legs 2 are symmetrically fixedly installed on both sides of the treatment tank 1. An mounting plate 3 is fixedly installed on one side of one of the support legs 2. A water pump 4 is fixedly installed at the bottom of the mounting plate 3. A sampling tube 5 is fixedly installed at the input end of the water pump 4, extending into the interior of the treatment tank 1. The water pump 4 creates a vacuum or negative pressure at its inlet using a mechanical device, drawing liquid from a lower position and pumping it to a higher position using the pressure difference. A transmission pipe 6 is fixedly installed at the output end of the water pump 4. Below the transmission pipe 6 and positioned... A wastewater heavy metal detector 7 is fixedly installed on one side of one of the support legs 2. The wastewater heavy metal detector 7 reacts with heavy metal ions in the water sample through electrodes to generate current or potential changes. These changes are used to estimate the concentration of metal ions. An inlet pipe 8 is fixedly installed on the top of the treatment box 1. A filter assembly 10 is installed inside the inlet pipe 8. An outlet pipe 9 is fixedly installed on the bottom of the treatment box 1. Multiple limiting grooves 11 are opened inside the treatment box 1. Multiple replacement components 12 are provided on the outer end of the treatment box 1. A sealing gasket 13 is fixedly installed on the top of the treatment box 1. The sealing gasket 13 is located at the outer end of the inlet pipe 8.

[0023] The water pump 4 can pump the treated wastewater from the treatment tank 1 to the wastewater heavy metal detector 7. The wastewater heavy metal detector 7 can detect the amount of heavy metals in the wastewater, which makes it easier to control the time when the staff replaces the activated carbon.

[0024] Please see Figure 1 , Figure 2 and Figure 3 The filter assembly 10 includes a mounting ring 101, which is fixedly installed inside the water inlet pipe 8. The mounting ring 101 has multiple slots 102 inside, and each slot 102 has a magnetic suction element 103 fixedly installed inside. The magnetic suction element 103 and the iron sheet 106 have opposite magnetic poles and attract each other. Each slot 102 has a sliding block 104 inside, and each block 104 has a filter screen 105 fixedly installed on the top and an iron sheet 106 fixedly installed on the bottom.

[0025] The filter screen 105 can be fixed by the attraction between the iron sheet 106 and the magnetic component 103, making it easier to install and remove the filter screen 105, and thus making the filtration of wastewater impurities more complete.

[0026] Please see Figure 1 and Figure 2 The replacement component 12 includes an electric slide rail 121, which is equipped with an electric motor that is powered by a power source and converted into mechanical energy to drive the movement of the slide rail. Each electric slide rail 121 is fixedly installed on one side of the processing box 1, and each electric slide rail 121 is slidably connected to a track block 122 at its outer end. Each track block 122 is fixedly installed on one side of a connecting plate 123, and each connecting plate 123 is fixedly installed on one side of a sealing plate 124. A placement box 125 is fixedly installed on the inner side of the sealing plate 124. The bottom of the placement box 125 is provided with multiple water outlet holes 126, and each placement box 125 is slidably connected to the limiting groove 11.

[0027] The electric slide rail 121 and track block 122 can drive the sealing plate 124 to be adjusted. The sealing plate 124 can drive the placement box 125 to be adjusted, so that the placement box 125 can be adjusted out of the interior of the treatment box 1, making it easier to replace the activated carbon inside the treatment box 1. The inner side of the sealing plate 124 has a rubber pad, which makes the sealing effect at the connection better.

[0028] Working principle: The operator places the filter screen 105 above the mounting ring 101, and then the locking block 104 below the filter screen 105 is locked inside the slot 102. The magnetic attraction between the magnetic component 103 and the locking block 104 fixes the locking block 104 inside the slot 102, thus fixing the filter screen 105 in place. Wastewater is transmitted to the surface of the filter screen 105 through the inlet pipe 8. The filter screen 105 filters the impurities in the wastewater, and then the wastewater flows into the placement tank 125. The activated carbon inside the placement tank 125 adsorbs the heavy metals in the wastewater. During the wastewater treatment process, the water pump 4 is started at regular intervals to pump the adsorbed wastewater out. First, the wastewater is drawn into the sampling tube 5, and then transferred to the surface of the wastewater heavy metal detector 7 through the transmission tube 6. The wastewater heavy metal detector 7 is used to detect the heavy metals inside the wastewater. If the detection value of the wastewater heavy metal detector 7 exceeds the standard, the staff can be reminded to replace the activated carbon. During the replacement of activated carbon, the electric slide rail 121 is activated. The electric slide rail 121 drives the track block 122 to adjust. The track block 122 drives the connecting plate 123 to adjust. The connecting plate 123 drives the sealing plate 124 to adjust. The sealing plate 124 drives the placement box 125 to adjust, so that the placement box 125 is adjusted out of the treatment box 1, and then the activated carbon inside the placement box 125 is replaced.
