Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment, and in particular to an activated carbon adsorption device for deep wastewater treatment. Background Technology

[0002] In the fields of environmental protection and water treatment, activated carbon is widely used in the advanced treatment of wastewater due to its unique adsorption properties. Activated carbon is a porous material with a well-developed pore structure and a huge surface area, which enables it to effectively adsorb various pollutants in water, including organic matter, heavy metal ions, suspended solids, etc.

[0003] For example, the prior art patent with authorization announcement number CN213506081U discloses an activated carbon adsorption device for sewage treatment, including a sewage adsorption tank and a sewage pretreatment tank. The sewage adsorption tank has three activated carbon filter elements inserted side by side in sequence inside. A flange is fixedly connected to the front of the sewage adsorption tank, and a drain pipe is connected to the back of the sewage adsorption tank. Water guide pipes are fixedly connected to both the front and back of the sewage pretreatment tank, and one end of the water guide pipe away from the sewage pretreatment tank is connected to the flange.

[0004] However, it was found during the use of the device that it was not convenient to automatically discharge and clean the filtered dirt, and that the labor intensity of replacing the activated carbon was relatively high, which reduced the convenience of use. Summary of the Invention

[0005] To address the aforementioned technical problems, this utility model provides a wastewater deep treatment activated carbon adsorption device that reduces particulate fouling on activated carbon, extends the service life of activated carbon, and improves the convenience of activated carbon replacement.

[0006] This utility model discloses an activated carbon adsorption device for deep wastewater treatment, comprising a tank and an inlet valve, the inlet valve being connected to the upper part of the outer wall of the tank; it also includes a sealing device, a cleaning device, a drain valve, a cylinder, a baffle plate, and multiple sets of filter screens. The cylinder is installed on the inner wall of the tank, the drain valve is connected to the lower part of the outer wall of the cylinder, the baffle plate is installed on the inner wall of the tank, and the inner wall of the baffle plate is connected to the outer wall of the cylinder. Multiple sets of water inlets are provided on the upper part of the outer wall of the cylinder, and multiple sets of filter screens are located at the water inlets of the cylinder. Sealing devices are provided at both the upper and lower ends of the cylinder to close the openings at both ends. The cleaning device is located on the tank and is used to clean the multiple sets of filter screens. Cleaning: Activated carbon is placed inside the cylinder. Wastewater is transported to the tank above the partition through the inlet valve. The wastewater then passes through the filter screen and enters the cylinder. The dirt inside the cylinder flows downwards, allowing the activated carbon to adsorb and purify the wastewater. The purified dirt is discharged through the drain valve. The wastewater is filtered through the filter screen, thereby improving the filtration and purification effect of particulate dirt in the wastewater, reducing the contamination of activated carbon by particulate dirt, and extending the service life of activated carbon. The cleaning device backwashes multiple sets of filter screens, thereby cleaning the dirt filtered by the filter screens. The bottom of the cylinder is opened through the sealing device, allowing the activated carbon inside the cylinder to be discharged, improving the convenience of activated carbon replacement.

[0007] Preferably, the sealing device includes a positioning device, multiple sets of cylinders, a top plate, a connecting rod, a sealing plate, and a cover plate. Multiple sets of cylinders are installed at the top of the tank. The top plate is installed on the moving end of the multiple sets of cylinders. The top of the connecting rod is connected to the bottom of the top plate, and the lower part of the connecting rod passes through the inside of the cylinder. The bottom of the connecting rod is connected to the top of the sealing plate, and the sealing plate is positioned at the lower opening of the cylinder. The cover plate is slidably installed on the outer wall of the connecting rod and is positioned at the top opening of the cylinder. A positioning device is provided on the cover plate to fix it in place. The multiple sets of cylinders drive the top plate downwards, causing the top plate to drive the connecting rod downwards, which in turn drives the sealing plate downwards, opening the lower opening of the cylinder and allowing the activated carbon inside the cylinder to be discharged. The sealing plate then closes the lower opening of the cylinder. By sliding the cover plate upwards, it is easy to add activated carbon through the upper part of the cylinder, improving the convenience of activated carbon replacement.

The pump body is installed on the outer wall of the storage tank, the pump body input end is connected to the storage tank, the pump body output end is connected to the hose, and the hose output end is connected to the cover plate. By closing the drain valve, the pump body draws clean water from the storage tank, and the drawn clean water is transported to the inside of the cylinder through the hose, so that the clean water is discharged through the filter screen to the upper part of the partition, thereby backwashing multiple sets of filter screens.

[0009] Preferably, the positioning device includes a kit and a set screw. The bottom end of the kit is connected to the top end of the cover plate, and the kit is slidably mounted on the connecting rod. The set screw is screwed onto the kit. By rotating and adjusting the set screw, the set screw can be slidably fixed to the kit, thereby fixing the cover plate with the kit.

[0010] Preferably, it also includes a guide channel, which is installed at the bottom of the tank; the activated carbon discharged from the cylinder falls into the guide channel and is guided out through the guide channel.

[0011] Preferably, it also includes a drain valve, which is connected to and installed on the outer wall of the tank; the drain valve discharges the backwashed dirt, improving the convenience of dirt cleaning.

[0012] Preferably, it also includes an observation window, which is connected and installed on the outer wall of the tank; by setting multiple sets of observation windows, the convenience of observing the cleanliness status of multiple sets of filters is improved.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Activated carbon is placed inside the cylinder, and sewage is transported to the tank above the partition through the inlet valve. Then, the sewage passes through the filter screen and enters the cylinder. The dirt inside the cylinder flows downward, thereby allowing the activated carbon to adsorb and purify the sewage. The purified dirt is discharged out through the drain valve. The sewage is filtered through the filter screen, thereby improving the filtration and purification effect of particulate dirt in the sewage, reducing the pollution of particulate dirt on the activated carbon, and extending the service life of the activated carbon. The cleaning device backwashes multiple sets of filter screens, thereby cleaning the dirt filtered by the filter screens. The bottom of the cylinder is opened through the sealing device, thereby allowing the activated carbon inside the cylinder to be discharged, improving the convenience of activated carbon replacement.
