Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of activated carbon cleaning equipment, specifically a self-cleaning activated carbon filter device. Background Technology
[0002] Activated carbon, as a widely used adsorbent material, is commonly used in air purification, water treatment, and gas filtration. Its extremely large specific surface area and porous structure enable it to adsorb and remove harmful substances (such as organic chemicals, gases, particles, and toxins) from water or air. Therefore, activated carbon is frequently used in air purification, water treatment, and industrial waste gas adsorption. Activated carbon can sometimes act as a catalyst carrier, participating in the catalytic process of certain chemical reactions, such as removing harmful substances from waste gases or liquids in some industrial reactions. During these processes, activated carbon gradually becomes contaminated with use, and its adsorption capacity decreases. Therefore, it needs to be cleaned and regenerated regularly. Traditional cleaning devices cannot circulate and clean the activated carbon during cleaning, resulting in incomplete cleaning. Utility Model Content
[0003] The purpose of this invention is to provide a self-cleaning activated carbon filter device to solve the problem that traditional cleaning devices cannot circulate and clean the activated carbon during cleaning, thus failing to clean it completely.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning activated carbon filter device, comprising a conical outer cylinder, a support, and a cleaning device installed inside the conical outer cylinder. The conical outer cylinder is a hollow shell with an upward opening, and the shell is made of transparent plexiglass. A water outlet pipe is connected to the outer circumference of the top of the conical outer cylinder, and a support is connected to the outer circumference of the conical outer cylinder. Several support rods are evenly distributed at the bottom of the support, and the support rods are in contact with the ground. The conical outer cylinder is set in a conical shape at one end of the support, and a discharge port is opened at the conical end.
[0005] The cleaning device includes a feeding pipe, an air source pipe, a water inlet sleeve, a material discharge sleeve, and a wastewater sleeve. The feeding pipe is a transparent plexiglass tube with a suction end at the bottom and a discharge end at the top. A gap is left between the suction end and the conical end of the conical outer cylinder to allow material to rise. An air source protective sleeve is fitted on the outer circumference of the feeding pipe, forming a space between the air source protective sleeve and the feeding pipe. One end of the air source pipe passes through the top of the conical outer cylinder and connects to an external air source, while the other end obliquely passes through the bottom of the feeding pipe. A water inlet sleeve is fitted on the outer circumference of the air source protective sleeve, with its upper and lower ends connected to the air source protective sleeve. The contact end of the sleeve is closed. The top of the inlet sleeve is connected to an inlet pipe, which passes through the conical outer cylinder and connects to an external water source. The bottom of the inlet pipe is connected to several water distributors. A discharge sleeve is fitted on the outer circumference of the discharge end of the feeding pipe. The discharge sleeve and the outer circumference of the discharge end of the feeding pipe are connected by a connecting plate, and a material falling space is formed between every two connecting plates. A wastewater sleeve is fitted on the outer circumference of the discharge sleeve. The top of the discharge sleeve is lower than the top of the wastewater sleeve. The bottom of the wastewater sleeve and the contact end of the discharge sleeve are closed. A wastewater pipe is connected to the wastewater sleeve, and the wastewater pipe is lower than the discharge pipe.
[0006] Preferably, it also includes a detachable first filter screen, which is disposed inside the material discharge sleeve. The first filter screen is lower than the top of the material discharge sleeve and abuts against the inner wall of the material discharge sleeve. A hole is opened at the contact end of the first filter screen and the air source pipe.
[0007] Preferably, it also includes a detachable second filter screen, which is fitted on the outer circumference of the wastewater sleeve, lower than the outlet pipe, and in contact with the inner wall of the conical outer cylinder.
[0008] Preferably, the first filter screen and the second filter screen are evenly provided with a plurality of small holes with a diameter of ∅2mm.
[0009] Preferably, the contact ends of the air source protective sleeve and the feeding pipe are both sealed.
[0010] Preferably, a plurality of connecting plates are evenly arranged at an angle on the outer circumference of the water inlet sleeve, and the other end of the connecting plate is connected to the inner wall of the conical outer cylinder.
[0011] Preferably, it also includes a flow meter connected to the gas source pipe.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This design allows activated carbon placed at the conical end of a conical outer cylinder to be drawn into a feeding pipe via a combination of air and water flow. As the activated carbon is conveyed through the feeding pipe to the discharge sleeve, the flow velocity drops sharply due to the change from a small diameter to a large diameter, creating turbulence. The activated carbon particles are cleaned by friction between the water flow, air bubbles, and particles, as well as by collisions with the inner wall of the discharge sleeve. During the tumbling process, the first filter screen blocks the activated carbon, and the material falls through the discharge sleeve to the top of the activated carbon inside the cylinder, thus circulating and cleaning the activated carbon within the cylinder.

[0022] 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.
[0023] Example 1: Please refer to Figure 1-4 This utility model provides an embodiment of a self-cleaning activated carbon filter device, comprising a conical outer cylinder 1, a support 14, and a cleaning device installed inside the conical outer cylinder 1. The conical outer cylinder 1 is a hollow shell with an upward opening, and it is the main body of the entire device, acting as a container to hold materials. The transparent plexiglass material allows for visualization of the internal operation and easy observation of the cleaning process, while also possessing a certain degree of strength and durability. A water outlet pipe 12 is connected to the outer circumference of the top of the conical outer cylinder 1, and the support 14 is connected to the outer circumference of the conical outer cylinder 1. Several support rods are evenly distributed at the bottom of the support 14, and the support rods are in contact with the ground. The support 14 supports the conical outer cylinder 1, ensuring its stability. The contact of the support rods with the ground ensures that the conical outer cylinder 1 remains upright and does not tilt during the cleaning process. The even distribution of the support rods ensures that the conical outer cylinder 1 is subjected to uniform force, improving the stability of the support. The conical outer cylinder 1 is conical at one end of the support 14, and a discharge port is opened at the conical end.
[0024] The cleaning device includes a feeding pipe 2, an air source pipe 3, a water inlet sleeve 5, a material discharge sleeve 8, and a wastewater sleeve 9. The feeding pipe 2 is a transparent plexiglass tube with a suction end at the bottom and a discharge end at the top. A gap is left between the suction end and the conical end of the conical outer cylinder 1 to allow material to rise. The feeding pipe 2 is the channel through which material enters the cleaning system from the conical end of the conical outer cylinder 1. During operation, after the conical outer cylinder 1 is filled with water, the air source pipe 3 outputs airflow obliquely to the bottom of the feeding pipe 2. The air bubbles drive the water flow and activated carbon to rise along the feeding pipe. An air source protective sleeve 4 is fitted on the outer circumference of the feeding pipe 2. The contact ends of the air source protective sleeve 4 and the feeding pipe 2 are both sealed. The space between the air source protective sleeve 4 and the feeding pipe 2 forms the placement space for the air source pipe 3. The air source pipe 3 is used to feed the material. Airflow is provided in pipe 2 to facilitate material flow or gas cleaning. Air source protective sleeve 4 encloses air source pipe 3 to prevent direct exposure. Simultaneously, air source pipe 3 continuously tilts upwards towards the bottom of feeding pipe 2, maintaining upward airflow and allowing bubbles to be transported. Under the combined action of water flow and air source, activated carbon is guided through feeding pipe 2. During this process, activated carbon particles, air source, and water flow simultaneously perform simple impact and friction washing on the activated carbon. One end of air source pipe 3 penetrates the top of the conical outer cylinder 1 and connects to an external air source, while the other end obliquely penetrates the bottom of feeding pipe 2. A water inlet sleeve 5 is fitted around the outer circumference of air source protective sleeve 4. The upper and lower ends of the water inlet sleeve 5 are sealed to the contact ends of air source protective sleeve 4. The top of the water inlet sleeve 5... A water inlet pipe 6 is connected, passing through the conical outer cylinder 1 and connecting to an external water source. The water inlet pipe 6 introduces water into the water inlet sleeve 5, which forms an independent water flow channel. After the water flow is slowed and pressure evened, it enters the water distributor 7 for distribution, ensuring uniform water distribution by minimizing flow velocity deviation at each outlet. A valve is connected to the pipeline. After flowing into the water inlet sleeve 5, the water flows through several water distributors 7 located at the bottom and into the conical outer cylinder 1. Several water distributors 7 are connected to the bottom of the water inlet pipe 6. Each water distributor 7 has multiple small holes or nozzles, with the openings of the holes and nozzles facing downwards, for continuously and uniformly transmitting water into the conical outer cylinder 1. After flowing out through the outlet of the water distributor 7, the water carries activated carbon particles. Because the bottom of the conical outer cylinder 1 is conical, the water flow is further enhanced by the conical shape of the water distribution device. Activated carbon is conveyed to the suction end of the feeding pipe 2, where it cooperates with air bubbles within the pipe for transport. A discharge sleeve 8 is fitted onto the outer circumference of the discharge end of the feeding pipe 2. The discharge sleeve 8 is connected to the outer circumference of the discharge end of the feeding pipe 2 via connecting plates, and a material falling space is formed between every two connecting plates. The discharge sleeve 8 cooperates with the first filter screen 11 to form a space that encloses the discharge end of the feeding pipe 2 and also forms a cleaning space. The first filter screen 11 resists the continuous rise of the activated carbon. After being resisted, the activated carbon is smoothly discharged along the falling space by its own gravity to the top of the activated carbon pile placed inside the conical outer cylinder 1. A wastewater sleeve 9 is fitted onto the outer circumference of the discharge sleeve 8, with the top of the discharge sleeve 8 lower than the top of the wastewater sleeve 9, creating a water level classification.When activated carbon is intercepted by the detachable first filter screen 11, it returns to the conical outer cylinder 1 along the inner channel of the discharge sleeve 8. Wastewater passes through the filter screen and enters the wastewater sleeve 9. The bottom end of the wastewater sleeve 9 is sealed to the contact end of the discharge sleeve 8. A wastewater pipe 10 is connected to the wastewater sleeve 9. The wastewater pipe 10 is lower than the outlet pipe 12. The wastewater pipe 10 discharges the sewage in the wastewater sleeve 9. As the water distributor 7 continuously supplies water into the conical outer cylinder 1, the water in the conical outer cylinder 1 continuously rises. The water in the conical outer cylinder 1 is discharged after reaching the outlet pipe 12. The system also includes a detachable first filter screen 11, which is installed inside the discharge sleeve 8. The first filter screen 11 is lower than the top end of the discharge sleeve 8. The first filter screen 11 is designed to be detachable for easy installation and maintenance, while preventing external debris from entering the discharge sleeve 8. The first filter screen 11 abuts against the inner wall of the discharge sleeve 8. A hole is opened at the contact end of the first filter screen 11 and the air source pipe 3. It also includes a removable second filter screen 13. When placing activated carbon to be cleaned, the second filter screen 13 is removed, and the activated carbon is placed inside the conical outer cylinder 1. This prevents external debris from entering the conical outer cylinder 1. The filter screen 13 is fitted onto the outer circumference of the wastewater sleeve 9, below the outlet pipe 12, and in contact with the inner wall of the conical outer cylinder 1. The first filter screen 11 and the second filter screen 13 are evenly provided with several small holes with a diameter of ∅2mm to ensure that the air supplied by the air source pipe 3 into the conical outer cylinder 1 can flow along the air source pipe 3. The water is discharged through the small holes in the filter screen. Several connecting plates are evenly arranged at an angle on the outer circumference of the inlet sleeve 5. The other end of each connecting plate is connected to the inner wall of the conical outer cylinder 1. The connecting plates support the inlet sleeve 5. Since the inlet sleeve 5 is connected to the air source protection sleeve 4 and the feeding pipe 2 as a whole, and supports the air source protection sleeve 4 and the feeding pipe 2, it also includes a flow meter connected to the air source pipe 3. A switch valve is also connected to the air source pipe 3.
[0025] The activated carbon to be cleaned is placed into the conical outer cylinder 1. After installing the second filter screen 13, water is injected into the water inlet sleeve 5 through the water inlet pipe 6. The water flow is evenly distributed by the water distributor 7 and injected into the conical outer cylinder 1 until the water level reaches the height of the discharge end of the feeding pipe 2. The air source pipe 3 is turned on, and the airflow is output obliquely from the bottom end of the feeding pipe 2, forming a group of bubbles. The bubbles and the water flow work together to stably lift the activated carbon at the bottom of the conical outer cylinder 1 along the channel of the feeding pipe 2. After the activated carbon particles rise with the water flow to the discharge end of the feeding pipe 2, they enter the cleaning space formed by the discharge sleeve 8 and the first filter screen 11. During this process, the water flow is from the small diameter feeding pipe. 2. The flow rate drops sharply as the material enters the large-diameter feed sleeve 8, creating turbulence and swirling around the discharge end of the feed pipe 2. During this process, the activated carbon particles are cleaned by the water flow, the friction between the particles and the air bubbles, and the collision with the inner wall of the feed sleeve 8. The cleaned activated carbon rises with the water flow to the position of the first filter screen 11 and is intercepted. Then, it falls back to the top accumulation layer of the conical outer cylinder 1 through the inner channel of the feed sleeve 8, achieving circulation cleaning. The wastewater containing impurities passes through the first filter screen 11 and enters the wastewater sleeve 9, and is discharged through the wastewater pipe 10. When the water level rises to the height of the outlet pipe 12, the water in the conical outer cylinder 1 is discharged through the outlet pipe 12.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
