Description

Technical Field

[0001] This utility model relates to the field of wastewater filtration technology, specifically to an activated carbon filter canister that facilitates filter media replacement. Background Technology

[0002] An activated carbon filter tank is a type of filter equipment with a tank-like outer shell, typically made of stainless steel or fiberglass, and filled with activated carbon. It is used to filter free matter, microorganisms, and some heavy metal ions from water, and can effectively reduce the color of the water. Activated carbon filter tanks are a commonly used water treatment device. As a pretreatment in water treatment desalination systems, they can adsorb residual chlorine that cannot be removed in the previous stage of filtration, effectively ensuring the service life of downstream equipment, improving the quality of effluent, and preventing pollution, especially preventing free residual oxygen poisoning of downstream reverse osmosis membranes and ion exchange resins.

[0003] Activated carbon filter cans are used to filter wastewater, but after a period of use, the filtration efficiency of the activated carbon filter media inside the filter element decreases, requiring replacement. Some filter elements are welded directly inside the filter can, making them impossible to disassemble and difficult to replace, thus affecting the filtration effect of the activated carbon filter can. Therefore, this solution provides an activated carbon filter can with easily replaceable filter media to address the aforementioned problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, an activated carbon filter canister that facilitates filter media replacement is provided. This technical solution addresses the problems mentioned in the background section.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An activated carbon filter canister with easy-to-replace filter media includes a filter canister, an inlet pipe fixedly connected to the upper left side of the filter canister, an outlet pipe fixedly connected to the lower right side of the filter canister, a fixed base fixedly connected to the inner wall of the filter canister, a filter element disposed inside the fixed base, a stirring mechanism fixedly installed inside the filter element, a guide plate disposed on the lower left side of the filter element, and a pair of electric push rods disposed on the right side of the filter element. The two electric push rods are symmetrically mounted on the lower right side of the fixed base, and a cleaning brush is fixedly connected to the output end of the electric push rods. The inner end of the cleaning brush abuts against the surface of the filter element.

[0007] Preferably, a cleaning door is provided on the lower right side of the filter tank, and a top cover is provided on the top of the filter tank. The top cover is fixedly connected to the upper end of the filter tank by a number of first bolts.

[0008] Preferably, a number of positioning blocks are fixedly connected to the inner end of the fixing base, and a number of positioning grooves are opened at the upper end of the filter element, the positioning grooves matching the positioning blocks.

[0009] Preferably, the lower right side surface of the filter element has a plurality of filter holes, and the lower left side of the filter element has a slag outlet.

[0010] Preferably, the upper inlet of the guide plate is connected to the slag outlet, the lower outlet of the guide plate is located at the cleaning door, a baffle is slidably connected to the upper inlet of the guide plate, the size of the baffle is larger than the size of the slag outlet, and the two sides of the guide plate are fixedly connected to the filter element by several sets of second bolts.

[0011] Preferably, the stirring mechanism includes a stirring motor and a stirring shaft. The stirring motor is fixedly installed at the lower end of the filter element, and the stirring shaft is rotatably installed inside the filter element. The output end of the stirring motor is fixedly connected to the lower end of the stirring shaft. Several sets of stirring rods are fixedly connected to the surface of the stirring shaft, and a rotating plate is fixedly connected to the surface of the lowest stirring rod.

[0012] Preferably, a protective shell is provided on the outside of the stirring motor, and the upper end of the protective shell is fixedly connected to the lower end of the filter element.

[0013] Compared with the prior art, this utility model proposes an activated carbon filter canister that facilitates filter media replacement, and has the following beneficial effects:

[0014] 1. In use, wastewater enters through the inlet pipe and flows into the filter element. The filter element is equipped with a stirring mechanism, which is driven by a motor to rotate the stirring shaft. The stirring shaft then drives the stirring rod to rotate, and the bottommost stirring rod in turn drives the rotating plate to rotate. This stirring mechanism keeps the activated carbon particles in motion, reducing clogging and extending the lifespan of the filter element and activated carbon. Simultaneously, it ensures that pollutants in the water can more fully contact the activated carbon, improving adsorption and thus enhancing filtration efficiency. Furthermore, an electric push rod drives a cleaning brush to periodically clean the filter element, reducing the probability of clogging and ensuring optimal filtration performance, thereby extending the filter element's lifespan.

[0015] 2. In this utility model, when the activated carbon inside the filter element needs to be replaced, open the cleaning door on the lower side of the filter tank, then align the collection component with the guide plate, and pull the baffle out from inside the guide plate, so that the activated carbon inside the filter element can be discharged from the slag outlet. With the help of the guide plate, the activated carbon can be collected quickly. At the same time, start the stirring mechanism inside the filter element. During the rotation, the stirring rod can loosen the activated carbon to prevent it from accumulating at the slag outlet. At the same time, the rotating plate pushes the activated carbon so that it can be quickly discharged from the slag outlet, cleaning out the used activated carbon. The whole process can quickly replace the filter media in the filter tank, speeding up the replacement speed of the activated carbon filter media inside the filter tank, and eliminating the need to cut the filter element, greatly reducing the cost and risk of filter media replacement, and extending the service life of the filter tank.

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] Reference Figure 1-5As shown, an activated carbon filter canister for easy replacement of filter media includes a filter canister 1. A water inlet pipe 2 is fixedly connected to the upper left side of the filter canister 1, and a water outlet pipe 3 is fixedly connected to the lower right side of the filter canister 1. A fixing seat 5 is fixedly connected to the inner wall of the filter canister 1. A filter element 6 is disposed inside the fixing seat 5. A stirring mechanism 8 is fixedly installed inside the filter element 6. A guide plate 9 is disposed on the lower left side of the filter element 6. A pair of electric push rods 10 are disposed on the right side of the filter element 6. The two electric push rods 10 are symmetrically installed on the lower right side of the fixing seat 5. A cleaning brush 11 is fixedly connected to the output end of the electric push rod 10. The inner end of the cleaning brush 11 abuts against the surface of the filter element 6. Wastewater enters through inlet pipe 2 and flows into filter element 6. Filter element 6 is equipped with an internal stirring mechanism 8. The stirring mechanism 8 is driven by a motor to rotate stirring shaft 802, which in turn drives stirring rod 803 to rotate. The bottommost stirring rod 803 then drives rotating plate 804 to rotate. The stirring mechanism 8 keeps the activated carbon particles in motion, thereby reducing clogging and extending the service life of filter element 6 and activated carbon. Simultaneously, it ensures that pollutants in the water can more fully contact the activated carbon, improving adsorption and thus enhancing filtration efficiency. Furthermore, an electric push rod 10 drives a cleaning brush 11 to periodically clean filter element 6, reducing the probability of clogging and ensuring its filtration effectiveness, thus extending its service life.

[0025] Specifically, in this embodiment, a cleaning door 101 is provided on the lower right side of the filter tank 1, and a top cover 4 is provided on the top of the filter tank 1. The top cover 4 is fixedly connected to the upper end of the filter tank 1 by several sets of first bolts 401.

[0026] Specifically, in this embodiment, a number of positioning blocks 501 are fixedly connected to the inner end of the fixing base 5, and a number of positioning grooves 601 are opened at the upper end of the filter element 6. The positioning grooves 601 match the positioning blocks 501. Through the cooperation of the positioning blocks 501 and the positioning grooves 601, the fixing base 5 and the filter element 6 are positioned and limited, thereby preventing the filter element 6 from shaking or rotating.

[0027] Specifically, in this embodiment, the lower right side surface of the filter element 6 has several sets of filter holes 602, and the lower left side of the filter element 6 has a slag outlet 603. Wastewater enters from the inlet pipe 2 and enters the filter element 6. The activated carbon placed inside the filter element 6 adsorbs and treats the wastewater. After treatment, the wastewater is discharged through the filter holes 602 and finally enters the next wastewater treatment process through the outlet pipe 3. The activated carbon that has been used for a long time is discharged through the slag outlet 603 for easy replacement.

[0028] Specifically, in this embodiment, the upper inlet of the guide plate 9 is connected to the slag outlet 603, the lower outlet of the guide plate 9 is located at the cleaning door 101, a baffle 901 is slidably connected at the upper inlet of the guide plate 9, the size of the baffle 901 is larger than the size of the slag outlet 603, and the two sides of the guide plate 9 are fixedly connected to the filter element 6 by several sets of second bolts 902. When the activated carbon inside the filter element 6 needs to be replaced, open the cleaning door 101 on the lower side of the filter tank 1, then align the collection component with the guide plate 9, and pull the baffle 901 out from inside the guide plate 9, so that the activated carbon inside the filter element 6 can be discharged from the slag outlet 603. With the help of the guide plate 9, the activated carbon can be collected quickly. At the same time, start the stirring mechanism 8 inside the filter element 6. During the rotation, the stirring rod 802 can loosen the activated carbon to prevent it from accumulating at the slag outlet 603. At the same time, the rotating plate 804 pushes the activated carbon so that it can be quickly discharged from the slag outlet 603, cleaning out the used activated carbon. The whole process can quickly replace the filter media in the filter tank 1, speeding up the replacement of the activated carbon filter media inside the filter tank 1, and there is no need to cut the filter element 6, which greatly reduces the cost and risk of filter media replacement and extends the service life of the filter tank 1.

[0029] Specifically, in this embodiment, the stirring mechanism 8 includes a stirring motor 801 and a stirring shaft 802. The stirring motor 801 is fixedly installed at the lower end of the filter element 6, and the stirring shaft 802 is rotatably installed inside the filter element 6. The output end of the stirring motor 801 is fixedly connected to the lower end of the stirring shaft 802. Several sets of stirring rods 803 are fixedly connected to the surface of the stirring shaft 802, and a rotating plate 804 is fixedly connected to the surface of the lowest stirring rod 803. The stirring mechanism 8 keeps the activated carbon particles in motion, thereby reducing clogging between particles, extending the service life of the filter element 6 and the activated carbon, and ensuring that pollutants in the water can come into more full contact with the activated carbon, improving the adsorption effect and thus improving the filtration effect. At the same time, when the activated carbon is replaced, the stirring mechanism 8 can stir and loosen the activated carbon to prevent it from accumulating at the slag outlet 603. The rotating plate 804 pushes the activated carbon so that it can be quickly discharged from the slag outlet 603, quickly cleaning out the used activated carbon.

[0030] Specifically, in this embodiment, a protective shell 7 is provided on the outside of the stirring motor 801, and the upper end of the protective shell 7 is fixedly connected to the lower end of the filter element 6.

[0031] The working principle of this invention is as follows: When in use, wastewater enters through the inlet pipe 2 and flows into the filter element 6. The filter element 6 is equipped with a stirring mechanism 8. This mechanism 8 is driven by a motor to rotate the stirring shaft 802, which in turn drives the stirring rod 803 to rotate. The bottommost stirring rod 803 then drives the rotating plate 804 to rotate. The stirring mechanism 8 keeps the activated carbon particles in motion, thereby reducing clogging and extending the service life of the filter element 6 and the activated carbon. Simultaneously, it ensures that pollutants in the water can fully contact the activated carbon, improving adsorption and thus enhancing filtration efficiency. Meanwhile, the cleaning brush 11, driven by an electric push rod 10, periodically cleans the filter element 6, reducing the probability of clogging and ensuring its filtration effect, thus extending its service life. The activated carbon inside the filter element 6 adsorbs and treats the wastewater. After treatment, the wastewater is discharged through the filter holes 602 and finally enters the next wastewater treatment process through the outlet pipe 3.

[0032] When the activated carbon inside the filter element 6 needs to be replaced, open the cleaning door 101 on the lower side of the filter tank 1, then align the collection component with the guide plate 9, and pull the baffle 901 out from inside the guide plate 9, so that the activated carbon inside the filter element 6 can be discharged from the slag outlet 603. With the help of the guide plate 9, the activated carbon can be collected quickly. At the same time, start the stirring mechanism 8 inside the filter element 6. During the rotation, the stirring rod 802 can loosen the activated carbon to prevent it from accumulating at the slag outlet 603. At the same time, the rotating plate 804 pushes the activated carbon so that it can be quickly discharged from the slag outlet 603, cleaning out the used activated carbon. The whole process can quickly replace the filter media in the filter tank 1, speeding up the replacement of the activated carbon filter media inside the filter tank 1, and there is no need to cut the filter element 6, which greatly reduces the cost and risk of filter media replacement and extends the service life of the filter tank 1.
