Description

Technical Field

[0001] This application relates to the field of activated carbon technology, and in particular to an automatic carbon extraction device for activated carbon filter beds. Background Technology

[0002] With rapid socio-economic development, water scarcity and water pollution have become increasingly prominent issues, leading to ever-increasing demands on water purification efficiency and stability in the water treatment industry. Activated carbon filters, as the core unit for deep water purification, directly impact effluent quality through their operational status. Activated carbon filter media, as the core consumable material of the filter, requires regular replacement or regeneration to ensure filter efficiency. Therefore, the efficiency and quality of activated carbon removal operations have become crucial control points in water treatment processes. Specifically, during the operating cycle of an activated carbon filter, the filter media will become saturated and ineffective. Typically, activated carbon removal operations are required every 1-2 years to remove the ineffective filter media and replenish it with new media.

[0003] In traditional methods, activated carbon extraction has long relied on manual labor, especially in small and medium-sized water treatment plants and older facilities, where this method is dominant. The specific process involves operators using shovels to scoop activated carbon filter media from the filter bed into temporary storage bins. Once full, these bins are manually moved to wheelbarrows and then pushed to a designated storage area. Furthermore, if the filter bed is deep, an electric hoist is used to lift the storage bins out of the filter bed.

[0004] However, the process of manually transferring spent filter media from the filter bed to the storage point is entirely reliant on manpower, with zero automation. Furthermore, surveys indicate that the average efficiency of manual carbon extraction is only 1.2-1.5 cubic meters of filter media per person per hour, and the quality of the work is greatly affected by subjective factors such as the operator's skill, physical strength, and sense of responsibility. Moreover, relying on manpower not only makes it difficult to maintain consistently high efficiency, but also makes it difficult to ensure consistency in the amount and location of extraction each time, thus affecting the distribution of filter media and the purification effect within the filter bed.

[0005] Therefore, there is an urgent need for a device to solve the technical problems mentioned above. Utility Model Content

[0006] Based on this, this application provides an automatic carbon extraction device for activated carbon filters, which can effectively solve the problems of high manual labor intensity, high labor costs and poor sewage treatment efficiency, thereby achieving the effects of reducing manual labor intensity, reducing labor costs and improving sewage treatment efficiency.

The separation unit has an inlet connected to the output of the water jet injector via a conveying pipeline, and a filtrate outlet connected to the backwash water tank via a return water pipeline. It is used to separate and recover the adsorbed mixture.

[0010] An alternative is a water jet, comprising a nozzle, a throat, and a diffuser connected in sequence; A nozzle is used to eject water that has been delivered to the water jetter via a high-pressure pipeline at high speed. The throat is used to mix the water flow with the activated carbon filter media adsorbed through the carbon pool outlet pipe to obtain an adsorption mixture; The diffuser tube is used to decelerate and pressurize the adsorbed mixture before transporting it to the separation unit through a delivery pipeline.

[0011] An alternative is a separation unit, including a microfilter; Microfiltration machines are used to separate adsorbed mixtures, and the separated water flows into the backwash water tank through a return water pipe.

[0012] An alternative is that the separation unit also includes a screenings tank; The screenings tank is connected to the filter media outlet of the microfilter and is used to recover the activated carbon filter media separated by the microfilter.

[0013] An alternative is a power unit comprising a first circulation pump and a second circulation pump; The high-pressure pipeline includes a high-pressure branch, a main branch, and a backup branch. The high-pressure branch is connected to the main branch and the backup branch.

The first circulation pump is used to provide power support for the water jet through the main branch and the high-pressure branch; The second circulation pump is used to start when the first circulation pump fails, and provides power support to the water jet in place of the first circulation pump through the backup branch and the high-pressure branch.

[0014] An alternative is that the high-pressure pipeline also includes a bypass branch, which is connected to both the high-pressure branch and the main branch, and the high-pressure branch is equipped with a flow meter.

The entire device is connected by pipelines to form a closed loop, and the entire carbon extraction process can be completed without manual intervention. This reduces labor intensity, labor costs and improves sewage treatment efficiency, effectively solving the problems of high labor intensity, high labor costs and poor sewage treatment efficiency.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In existing technologies, activated carbon extraction operations have long relied on manual labor, especially in small and medium-sized water treatment plants and older water treatment plants, where this method still dominates. Specifically, operators use shovels to scoop activated carbon filter media from the filter tank into temporary storage bins. Once full, the bins are manually transported to wheelbarrows and then pushed to designated stacking areas. If the filter tank is deep, an electric hoist is used to lift the storage bins out of the filter tank.

[0025] However, the process of manually transferring spent filter media from the filter bed to the storage point is entirely reliant on manpower, with zero automation. Furthermore, surveys indicate that the average efficiency of manual carbon extraction is only 1.2-1.5 cubic meters of filter media per person per hour, and the quality of the work is greatly affected by subjective factors such as the operator's skill, physical strength, and sense of responsibility. Moreover, relying on manpower not only makes it difficult to maintain consistently high efficiency, but also makes it difficult to ensure consistency in the amount and location of extraction each time, thus affecting the distribution of filter media and the purification effect within the filter bed.

[0026] Therefore, this application provides an automatic activated carbon extraction device for activated carbon filters. It adopts a three-stage design of "power drive - pipeline transportation - separation and storage". Power is provided by the power unit 5, and the carbon extraction and separation mechanism 4 is used to form a negative pressure to extract filter media, separate water and collect and recycle. The entire device is connected by pipelines to form a closed loop. The entire carbon extraction process can be completed without manual intervention, thereby reducing the intensity of manual labor, reducing labor costs and improving the efficiency of sewage treatment. It can effectively solve the problems of high manual labor intensity, high labor costs and poor sewage treatment efficiency.

[0027] The following is a detailed description of the automatic carbon extraction device for activated carbon filter provided in this embodiment, with reference to the accompanying drawings. Figure 1 As shown, it includes: a carbon filter tank 1 and a backwash water tank 2; a carbon filter tank 1 is equipped with a carbon filter tank discharge pipe 3, a carbon extraction and separation mechanism 4 is installed between the carbon filter tank 1 and the backwash water tank 2, and a power unit 5 is installed in the backwash water tank 2; the carbon filter tank 1 contains activated carbon, which is used to remove various pollutants from the water; the carbon filter tank discharge pipe 3 is used to adsorb the activated carbon in the carbon filter tank 1; the carbon extraction and separation mechanism 4 is connected to the carbon filter tank discharge pipe 3, and is used to control the adsorption of activated carbon in the carbon filter tank 1 by the carbon filter tank discharge pipe 3, and to separate and extract the adsorbed activated carbon; the power unit 5 is connected to the carbon extraction and separation unit, and is used to provide power support for the carbon extraction and separation unit; the backwash water tank 2 is used to install the power unit 5 and to recycle the water separated by the carbon extraction and separation mechanism 4.

[0028] Specifically, the carbon filter 1 contains activated carbon, which can remove various pollutants from the water to improve water quality safety. The carbon filter 1, serving as the carrier for the activated carbon, is constructed with reinforced concrete. The depth of the filter can be set to 4-6 meters, and the bottom is tapered, with a cone angle typically set to 60° to facilitate the accumulation of filter media. A 150mm diameter mounting hole is pre-drilled at the center of the bottom of the carbon filter 1 to fix the carbon filter outlet pipe 3. A sealing flange is installed around the hole to prevent leakage.

[0029] The carbon tank discharge pipe 3 is used to adsorb activated carbon in the carbon filter tank 1. It is made of DN100 seamless steel pipe, and its length can be set according to the depth of the carbon filter tank 1, generally 4.5-6.5 meters. One end of the carbon tank discharge pipe 3 extends into the bottom of the carbon filter tank 1. Along the length of the carbon tank discharge pipe 3 inside the carbon filter tank 1, a fixed support is installed every 1 meter. The fixed support is fixedly connected to the inner wall of the carbon filter tank 1 to ensure the stability of the carbon tank discharge pipe 3.

[0030] The carbon extraction and separation mechanism 4 is connected to the carbon tank outlet pipe 3 and is used to control the adsorption of activated carbon in the carbon filter tank 1 by the carbon tank outlet pipe 3, as well as to separate and extract the adsorbed activated carbon. The power unit 5 is connected to the carbon extraction and separation unit and provides power support for the unit. The backwash water tank 2, commonly used in backwashing systems, is used to install the power unit 5 and to recover and reuse the water separated by the carbon extraction and separation mechanism 4.

[0031] The above operation adopts a three-stage design of "power drive - pipeline transportation - separation and storage". Power is provided by power unit 5, and negative pressure is generated by carbon extraction and separation mechanism 4 to extract filter media, separate water and collect and recycle. The entire device is connected by pipelines to form a closed loop, and the entire carbon extraction process can be completed without manual intervention, thereby reducing the intensity of manual labor, reducing labor costs and improving the efficiency of sewage treatment.

[0032] Preferred, refer to Figure 1 As shown, multiple suction heads 31 are installed at the bottom of the carbon pool discharge pipe 3 along its length. Multiple feed holes are evenly distributed around the suction heads 31 for adsorbing activated carbon in the carbon filter pool 1.

[0033] Specifically, multiple suction heads 31 are installed along the length of the bottom of the carbon pool discharge pipe 3. The suction heads 31 are funnel-shaped and generally have a diameter of 200mm. Multiple feed holes are evenly distributed around the suction heads 31, generally up to 8, and their diameter can be set to 20mm.

[0034] In the above operation, the suction head 31 is set in a funnel shape, which can increase the suction area. In combination with the conical structure at the bottom of the carbon filter tank 1, it can ensure that the filter material is extracted more evenly and avoid local accumulation caused by manual shoveling. At the same time, the setting of the feed hole can prevent large impurities from entering the carbon tank discharge pipe 3.

[0035] Preferably, refer to Figure 1As shown, the carbon extraction and separation mechanism 4 includes a water jet injector 41 and a separation unit 42. The water jet injector 41 has an inlet connected to the outlet of the power unit 5 via a high-pressure pipeline 6, an inlet connected to the outlet of the carbon pool discharge pipe 3, and an outlet connected to the separation unit 42 via a conveying pipeline. It is used to control the carbon pool discharge pipe 3 to adsorb and mix the activated carbon in the carbon filter tank 1 under the action of the power unit 5, so as to obtain an adsorbed mixture, and to convey the adsorbed mixture to the separation unit 42. The separation unit 42 has an inlet connected to the outlet of the water jet injector 41 via a conveying pipeline, and a filtrate outlet connected to the backwash water tank 2 via a return water pipeline. It is used to separate and recover the adsorbed mixture.

[0036] In one feasible embodiment, the water jet ejector 41 includes a nozzle, a throat, and a diffuser connected in sequence; the nozzle is used to eject water that is delivered to the water jet ejector 41 at high speed through the high-pressure pipeline 6; the throat is used to mix the water flow with the activated carbon filter material adsorbed through the carbon pool discharge pipe 3 to obtain an adsorption mixture; the diffuser is used to decelerate and pressurize the adsorption mixture and then transport it to the separation unit 42 through the conveying pipeline.

[0037] Here, the water jet ejector 41 can adopt a Venturi tube structure, made of 304 stainless steel, with a nominal diameter generally set to 125mm and a flow rate generally set to 0-80m³ / h. Specifically, the water jet ejector 41 includes a nozzle, a throat, and a diffuser connected in sequence; the nozzle has its inlet connected to the outlet of the power unit 5 via a flange through a high-pressure pipeline 6, which can spray the water delivered to the water jet ejector 41 at high speed through the high-pressure pipeline 6; the throat has one end connected to the outlet of the nozzle and the other end connected to the outlet of the carbon pool discharge pipe 3 via a flange, which creates a negative pressure under the action of the nozzle, drawing the filter media at the bottom of the carbon filter pool 1 into the throat through the carbon pool discharge pipe 3, where the filter media and water mix to form a solid-liquid mixture with a concentration of about 10%, i.e., the adsorption mixture; the diffuser has one end connected to the throat and the other end connected to the separation unit 42 via a conveying pipeline, which can decelerate and pressurize the adsorption mixture before conveying it to the separation unit 42 via the conveying pipeline.

[0038] The above operation, powered by the power unit 5, utilizes the negative pressure generated when high-pressure water flows through the nozzle to draw the filter media from the carbon tank outlet pipe 3 and mix it with the water flow, forming a gas-liquid-solid three-phase flow, which is an adsorption mixture. This achieves automated extraction of the filter media, solving the problem of low efficiency in manual material handling and improving the efficiency of filter media extraction.

[0039] In one possible implementation, the separation unit 42 includes a microfilter 421; the microfilter 421 is used to separate the adsorbed mixture and to send the separated water into the backwash water tank 2 through a return water pipe.

[0040] Here, a rotary drum microfilter 421 can be used, with a filtration accuracy typically set to 0.5mm, a drum diameter typically set to 800mm, a length typically set to 1100mm, and a material of 316 stainless steel. The drum surface is covered with a polyester filter screen, and the flow rate is typically set to 102 m³ / h, effectively separating the filter media from the water. Specifically, the microfilter 421 has its inlet connected to the output port of the water jet injector 41 via a conveying pipeline, and its filtrate outlet connected to the backwash tank 2 via a return water pipeline. This is used to separate and recover the adsorbed mixture. When the drum of the microfilter 421 rotates, the filter screen traps the filter media, and water flows back to the backwash tank 2 through the filter screen gaps via the return water pipeline. Simultaneously, the microfilter 421 can be equipped with a flushing device, using a high-pressure water gun to clean the filter screen online, thus preventing clogging.

[0041] The above operations, along with the online flushing function and water circulation design of the microfilter 421, can reduce water waste and greatly improve water-saving efficiency compared to manual material handling.

[0042] In one possible implementation, the separation unit 42 further includes a screenings tank 422; the screenings tank 422 is connected to the filter media outlet of the microfilter 421 and is used to recover the activated carbon filter media separated by the microfilter 421.

[0043] Here, the screenings trough 422 adopts a spiral scaling trough body. The trough width can generally be set to 500mm, the trough length to 1200mm, and the installation inclination angle to 0°. Specifically, the screenings trough 422 is connected to the filter media outlet of the microfilter 421. The filter media, under the influence of gravity and the rotation of the microfilter 421's drum, falls into the screenings trough 422 via a chute, thus realizing the recovery of the activated carbon filter media separated by the microfilter 421. Furthermore, an electric gate valve is installed at the bottom of the screenings trough 422 for convenient unloading of the activated carbon filter media.

[0044] The above operations, including the fully enclosed pipeline transportation and the setting of the screenings trough 422, effectively control the diffusion of activated carbon dust, thereby improving the working environment.

[0045] Preferably, the power unit 5 includes a first circulation pump 51 and a second circulation pump 52; the high-pressure pipeline 6 includes a high-pressure branch 61, a main branch 62, and a backup branch 63, wherein the high-pressure branch 61 is connected to the main branch 62 and the backup branch 63, the main branch 62 is connected to the first circulation pump 51, and the backup branch 63 is connected to the second circulation pump 52; the first circulation pump 51 is used to provide power support to the water jet 41 through the main branch 62 and the high-pressure branch 61; the second circulation pump 52 is used to start when the first circulation pump fails, and provides power support to the water jet 41 in place of the first circulation pump through the backup branch 63 and the high-pressure branch 61.

[0046] Here, the power unit 5 can be a horizontal centrifugal pump, model CP511-100, with a flow rate typically set to 65 m³ / h, a head of 30 m, and a speed of 2980 rpm. It is made of 304 stainless steel and possesses corrosion-resistant properties. Specifically, the power unit 5 includes a first circulating pump 51 and a second circulating pump 52; the high-pressure pipeline 6 includes a high-pressure branch 61, a main branch 62, and a backup branch 63, all of which are connected. The inlet of the first circulating pump 51 is connected to the supernatant pipeline of the backwash water tank 2, and its outlet provides continuous and stable power support to the water jet injector 41 through the main branch 62 and the high-pressure branch 61. The main branch 62 is equipped with a flexible joint, a check valve, and a butterfly valve to control its on / off state. Simultaneously, the first circulating pump 51 is equipped with a frequency converter, which can adjust the flow rate and pressure by regulating the speed to adapt to different operating conditions.

[0047] The backup branch line 63 is also equipped with a flexible joint, a check valve, and a butterfly valve in sequence to control the on / off state of the backup branch line 63. When the first circulation pump 51 fails, the butterfly valve of the first circulation pump 51 is closed, and the butterfly valve of the second circulation pump 52 is started. Since the inlet of the second circulation pump 52 is connected to the supernatant pipe of the backwash water tank 2, and the outlet is connected to the backup branch line 63, when the first circulation pump 51 fails, the backup branch line 63 and the high-pressure branch line 61 can replace the first circulation pump 51 to provide power support for the water jet injector 41.

[0048] The above operation, by setting up a first circulation pump 51 and a second circulation pump 52, enables the second circulation pump 52 to provide power support for the water jet 41 when the first circulation pump 51 fails, thereby improving the overall stability of the device.

[0049] Preferably, the high-pressure pipeline 6 further includes a bypass branch 64, which is connected to both the high-pressure branch 61 and the main branch 62, and the high-pressure branch 61 is equipped with a flow meter 65; the bypass branch 64 is used to open when the flow meter 65 is damaged, so as to ensure the smooth flow of the high-pressure branch 61 and deliver high-pressure water flow to the water jet 41.

[0050] Specifically, the high-pressure pipeline 6 also includes a bypass branch 64, which is connected to both the high-pressure branch 61 and the main branch 62. The bypass branch 64 is equipped with a butterfly valve, which is normally closed. The high-pressure branch 61 has two butterfly valves spaced apart, with a flow meter 65 between them. Normally, both butterfly valves in the high-pressure branch 61 are open. If the flow meter 65 fails, both butterfly valves in the high-pressure branch 61 close, and the butterfly valve in the bypass branch 64 opens to ensure the smooth flow of high-pressure water to the water jet injector 41.

[0051] The above operation, after the flow meter 65 is damaged, delivers high-pressure water flow to the water jet injector 41 through the bypass branch 64, providing further assurance for the normal operation of the entire device.

[0052] Preferably, the high-pressure pipeline 6 further includes a return branch 66, which is connected to the high-pressure pipeline 61; the return branch 66 is used to start when the pressure in the high-pressure pipeline 61 is too high, to perform a pressure relief operation.

[0053] Specifically, the high-pressure pipeline 6 also includes a return branch 66, which is connected to the high-pressure branch 61. The return branch 66 is equipped with a butterfly valve, which is normally closed. When the pressure in the high-pressure branch 61 is too high, the butterfly valve is opened to relieve the pressure.

[0054] The above operation, by setting up a return branch 66, enables pressure relief when the pressure in the high-pressure branch 61 is too high, thus providing further assurance for the stable operation of the entire device.

[0055] Preferably, the high-pressure pipeline 6 also includes a dredging branch 67, which is connected to the high-pressure branch 61 and the coal pool discharge pipe 3; the dredging branch 67 is used to open when the coal pool discharge pipe 3 is blocked to perform a dredging operation.

[0056] Specifically, the high-pressure pipeline 6 also includes a dredging branch 67, which is connected to the high-pressure branch 61 and the charcoal pool discharge pipe 3. The dredging branch 67 is equipped with a butterfly valve, which is normally closed. Butterfly valves are also installed between the water jet ejector 41 and the charcoal pool discharge pipe 3, and between the high-pressure branch 61 and the water jet ejector 41. Normally, both of these butterfly valves are open. However, when the charcoal pool discharge pipe 3 is blocked, the butterfly valves between the water jet ejector 41 and the charcoal pool discharge pipe 3, and between the high-pressure branch 61 and the water jet ejector 41, are closed, while the butterfly valve of the dredging branch 67 opens to complete the dredging operation of the charcoal pool discharge pipe 3.

[0057] It should also be noted that a pressure gauge is installed at the end of the charcoal pool discharge pipe 3 near the water jet injector 41 to measure the pressure of the current passage.

[0058] The above operation, by setting up the branch road 67, enables the unblocking of the coal pool discharge pipe 3, providing further assurance for the coal extraction operation.

[0059] The implementation principle of this embodiment is as follows: During use, first check whether the connections of each pipeline are tight, whether the oil level of the power unit 5 is normal, whether the filter screen of the microfilter 421 is clean, and whether the screenings trough 422 is empty. After all checks are completed, start the first circulation pump 51. Once the pressure stabilizes, the water jet injector 41 automatically forms a negative pressure and begins to extract the filter media. Simultaneously, start the microfilter 421. The separation effect of the filter media is controlled by adjusting the speed of the microfilter 421. After the carbon extraction operation is completed, turn off the power unit 5. After the material in the pipeline is emptied, turn off the microfilter 421. Finally, close the screenings trough 422 to stop conveying the filter media, completing one carbon extraction cycle. The aforementioned method, in conjunction with the power unit 5 and the water jet injector 41, enables automatic extraction and conveying of filter media, replacing manual operation. This eliminates the need for manual intervention in the carbon extraction process, thereby reducing labor intensity and labor costs. Simultaneously, the carbon discharge microfilter 421 filters the filter media, ensuring the quality of the filter media conveyed to the screenings trough 422. Compared to manual material extraction, the efficiency is significantly improved, making the operation of the activated carbon filter 1 more stable and thus ensuring the effectiveness of water treatment.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
