Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater heavy metal treatment device with a filtration structure. Background Technology

[0002] With the rapid development of industrialization, the discharge of industrial wastewater containing heavy metals has been increasing, posing a serious threat to the environment and human health. The treatment of heavy metals in wastewater can be achieved by adding chemical agents to cause heavy metal ions to form solid precipitates, and then filtering and separating the precipitates to remove heavy metals from the wastewater.

[0003] In current wastewater heavy metal treatment devices, sediment tends to adhere to the surface of the filter structure during long-term use, requiring regular cleaning to prevent clogging and inconvenience.

[0004] Therefore, to address the above issues, a wastewater heavy metal treatment device with a filtration structure can be designed. This device can automatically clean the filtration structure during the wastewater treatment process, reducing manual intervention and effectively preventing clogging, making it more convenient. Utility Model Content

The adsorption tank is fixedly installed on one side of the treatment tank. The connecting pipe passes through the treatment tank, with its output end located above the adsorption tank. A control valve is installed around the connecting pipe. The filter cover is fixedly installed at one end of the connecting pipe and is located inside the treatment tank. A mounting frame is fixedly installed inside the connecting pipe. The rotating shaft is rotatably connected to one side of the mounting frame, passing through the filter cover and rotatably connected to it. A cleaning scraper is fixedly installed around the rotating shaft, and the cleaning scraper is in contact with the surface of the filter cover. Two sets of staggered impellers are fixedly installed around the rotating shaft, and the impellers are located inside the connecting pipe.

A filter cover is installed to filter the wastewater discharged into the adsorption tank through the connecting pipe, preventing solid sediments and other impurities from entering the adsorption tank. A mounting bracket is installed to support and install the rotating shaft. When water flows into the adsorption tank through the connecting pipe, it will actuate the impeller to rotate, thereby driving the rotating shaft and the cleaning scraper fixedly installed around the rotating shaft to rotate synchronously. When the cleaning scraper rotates, it will clean the surface of the filter cover, remove the debris adhering to the surface of the filter cover, and prevent the filter cover from becoming clogged.

[0008] Preferably, a water inlet is connected to one side of the treatment tank, and a drain pipe is connected to the lower end of the treatment tank. A drain valve is installed at the connection between the drain pipe and the treatment tank.

[0009] Preferably, a drain pipe is connected to one side of the adsorption box, and a drain valve is provided at the connection between the drain pipe and the adsorption box.

The filter cover filters the wastewater flowing into the adsorption tank through the connecting pipe, preventing solid sediments and other impurities from entering the adsorption tank. When water flows into the adsorption tank through the connecting pipe, the water flow will drive the impeller to rotate, thereby driving the rotating shaft and the cleaning scraper fixedly installed around the rotating shaft to rotate synchronously. When the cleaning scraper rotates, it will clean the surface of the filter cover, removing debris adhering to the surface of the filter cover and preventing the filter cover from becoming clogged. This automatically cleans the filter cover, reducing manual intervention and making it more convenient. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 and Figure 4This utility model provides an embodiment of a wastewater heavy metal treatment device with a filtration structure, comprising a treatment tank 1, an adsorption tank 2, a connecting pipe 3, a control valve 301, a filter cover 302, a mounting frame 303, a rotating shaft 304, a cleaning scraper 305, and an impeller 306. The adsorption tank 2 is fixedly installed on one side of the treatment tank 1. The connecting pipe 3 passes through the treatment tank 1, with its output end located above the adsorption tank 2. The control valve 301 is arranged around the connecting pipe 3. The filter cover 302 is fixedly installed at one end of the connecting pipe 3 and is located inside the treatment tank 1. The mounting frame 303 is fixedly installed inside the connecting pipe 3. The rotating shaft 304 is rotatably connected to one side of the mounting frame 303, passing through and rotatably connecting to the filter cover 302. A cleaning scraper 305 is fixedly installed around the rotating shaft 304, and the cleaning scraper 305 is in contact with the surface of the filter cover 302. Two sets of staggered impellers 306 are fixedly installed on the periphery of 304, and the impellers 306 are located inside the connecting pipe 3. The wastewater in the treatment tank 1 can be discharged into the adsorption tank 2 through the connecting pipe 3. The opening and closing of the connecting pipe 3 can be controlled by the control valve 301. The filter cover 302 can filter the wastewater discharged into the adsorption tank 2 through the connecting pipe 3 to prevent solid sediments and other impurities from entering the adsorption tank 2. The rotating shaft 304 is supported and installed by the mounting bracket 303. When water flows into the adsorption tank 2 through the connecting pipe 3, it will cause the impellers 306 to rotate, thereby driving the rotating shaft 304 and the cleaning scraper 305 fixedly installed on the periphery of the rotating shaft 304 to rotate synchronously. When the cleaning scraper 305 rotates, it will clean the surface of the filter cover 302, remove the debris adhering to the surface of the filter cover 302, and prevent the filter cover 302 from becoming blocked.

[0023] Please see Figure 1 and Figure 2In this embodiment, a water inlet 101 is connected to one side of the treatment tank 1, and a drain pipe 102 is connected to the lower end of the treatment tank 1. A drain valve 103 is provided at the connection between the drain pipe 102 and the treatment tank 1. The water inlet 101 allows wastewater to be transported into the treatment tank 1, and the drain valve 103 controls the drain pipe 102 to discharge heavy metal precipitates and other impurities that have settled in the treatment tank 1. A drain pipe 201 is connected to one side of the adsorption tank 2, and a drain valve 202 is provided at the connection between the drain pipe 201 and the adsorption tank 2. The drain valve 202 controls the discharge of heavy metal precipitates and other impurities that have settled in the treatment tank 1. The drain pipe 201 is controlled to discharge the treated wastewater from the adsorption tank 2. Two sets of porous storage boxes 203 are linearly arranged inside the adsorption tank 2. The porous storage boxes 203 are slidably connected to the adsorption tank 2, and two sets of hanging ears 204 are symmetrically fixed to the upper end of the porous storage boxes 203. The porous storage boxes 203 can be loaded with adsorption materials such as activated carbon, sepiolite, and ion exchange resin to further adsorb and treat the wastewater after sedimentation and filtration. The hanging ears 204 facilitate the loading and unloading of the porous storage boxes 203, making it easy to replace the loaded adsorption materials and ensuring the adsorption effect.

[0024] Please see Figure 1 and Figure 3In this embodiment, two sets of porous storage boxes 203 are linearly arranged inside the adsorption box 2. The porous storage boxes 203 are slidably connected to the adsorption box 2, and two sets of hanging ears 204 are symmetrically fixedly installed on the upper end of the porous storage boxes 203. The porous storage boxes 203 can be loaded with adsorption materials such as activated carbon, sepiolite, and ion exchange resin to further adsorb and treat the wastewater after sedimentation and filtration. The hanging ears 204 facilitate the loading and unloading of the porous storage boxes 203, making it easy to replace the loaded adsorption materials and ensuring the adsorption effect. A partition 401 is fixedly installed inside the treatment box 1, and a dosing tank 402 is fixedly installed on the upper end of the partition 401. The partition 401 divides the upper part of the treatment box 1, increasing the retention time of wastewater inside the treatment box 1. The dosing tank 402 allows for the dosing of chemicals within the treatment box 1. Chemical agents are added to the treatment tank 1, causing heavy metal ions to precipitate. Multiple sets of fixing brackets 501 are fixedly installed on both sides of the partition 401. An air supply pipe 502 is installed around the perimeter of the partition 401, and the air supply pipe 502 is fixedly connected to the partition 401 via the fixing brackets 501. One end of the air supply pipe 502 is equipped with an air nozzle interface 503. Multiple sets of aeration pipes 504 are connected to the lower end of the air supply pipe 502, and aeration nozzles 505 are connected to the lower end of each aeration pipe 504. The air supply pipe 502 is supported and installed by fixing the components. An external air supply device can be connected via the air nozzle interface 503 to supply gas into the air supply pipe 502. The gas is then delivered to each aeration nozzle 505 via the aeration pipes 504 and sprayed out, effectively promoting the chemical reaction in the treatment tank 1 and agitating the wastewater, allowing the agents to fully contact the wastewater.

[0025] During operation, the control valve 301 is first closed, and the wastewater to be treated is transported into the treatment tank 1. Chemical agents are then added into the treatment tank 1 using the dosing tank 402, causing the heavy metal ions in the wastewater to precipitate solidly. An external air supply device can be connected through the air nozzle interface 503 to supply gas into the air supply pipe 502. The gas is then delivered to each aeration nozzle 505 through the aeration pipe 504, which can effectively promote the chemical reaction in the treatment tank 1 and agitate the wastewater in the treatment tank 1, so that the agents can fully contact the wastewater.

[0026] When the water level in the treatment tank 1 overflows the connecting pipe 3, continue the input of sewage and open the control valve 301. The water will flow into the adsorption tank 2 through the connecting pipe 3. At this time, the sewage added to the treatment tank 1 through the water inlet 101 will be blocked by the partition 401, prolonging the retention time in the treatment tank 1, so that it can fully contact the chemical agent.

[0027] The filter cover 302 can be used to filter the sewage discharged into the adsorption box 2 through the connecting pipe 3, preventing solid sediments and other impurities from entering the interior of the adsorption box 2. When water flows through the connecting pipe 3, it will cause the impeller 306 to rotate, thereby driving the rotating shaft 304 and the cleaning scraper 305 fixedly installed on the periphery of the rotating shaft 304 to rotate synchronously. When the cleaning scraper 305 rotates, it will clean the surface of the filter cover 302, remove the debris adhering to the surface of the filter cover 302, and prevent the filter cover 302 from becoming blocked.

[0028] The porous storage box 203 can be loaded with adsorption materials such as activated carbon, sepiolite, and ion exchange resin to further adsorb and treat the filtered wastewater, thereby improving the quality of wastewater treatment. Then, the drain valve 202 controls the drain pipe 201 to discharge the treated wastewater. The hanging ears 204 can be used to easily load and unload the porous storage box 203, making it convenient to replace the loaded adsorption materials and ensure the adsorption effect.

[0029] After a period of processing, the drain valve 103 is used to control the drain pipe 102, thereby discharging the heavy metal precipitates and other impurities retained in the treatment tank 1.

[0030] Through the above steps, wastewater in treatment tank 1 can be discharged into adsorption tank 2 through connecting pipe 3. The wastewater passing through connecting pipe 3 is filtered by filter cover 302. When water flows into adsorption tank 2 through connecting pipe 3, it will cause impeller 306 to rotate, thereby driving shaft 304 and cleaning scraper 305 fixedly installed around shaft 304 to rotate synchronously. When the cleaning scraper 305 rotates, it will clean the surface of filter cover 302, remove debris adhering to the surface of filter cover 302, prevent filter cover 302 from clogging, effectively reduce manual intervention, and prevent clogging, making it more convenient. This solves the problem that in current wastewater heavy metal treatment devices, sediment is easily adsorbed on the surface of the filter structure during long-term use, requiring regular cleaning, otherwise it is easy to cause clogging, which is not convenient.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
