Description

Technical Field

[0001] This utility model relates to the field of activated carbon filters, and in particular to an activated carbon filter that facilitates the replacement of activated carbon. Background Technology

[0002] An activated carbon filter is a device that uses activated carbon as a filter medium to remove impurities, odors, and harmful substances from water or gas. Activated carbon is a porous material with a large surface area, which allows it to adsorb a large number of molecules. During the filtration process, water or gas passes through the activated carbon layer, where pollutants are adsorbed into the pores of the activated carbon, thus purifying the fluid. Activated carbon filters are widely used in drinking water purification, air purification, industrial wastewater treatment, and chemical treatment.

[0003] In current practice, to facilitate activated carbon replacement, filters typically employ a method of replacing the entire activated carbon filter layer. However, this method has a significant drawback: it requires the removal of numerous equipment components. The need to disassemble and reinstall these components makes the entire replacement process complex and time-consuming, greatly reducing efficiency. This not only increases maintenance costs but may also lead to unnecessary equipment malfunctions during the replacement process. Utility Model Content

[0004] The main objective of this invention is to provide an activated carbon filter that facilitates the replacement of activated carbon, which can effectively solve the problems mentioned in the background art.

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

[0006] An activated carbon filter that facilitates the replacement of activated carbon includes a support, a filter canister, a sealing cover, and a pipe. The filter canister is mounted on the support, the sealing cover is mounted on the filter canister via a locking device, and the pipe is mounted on the sealing cover and the filter canister.

[0007] The filter can is connected to an activated carbon filter layer inside the can. The activated carbon filter layer is confined inside the filter can by a filter screen, and the filtration operation is achieved through the activated carbon filter layer.

[0008] A fixed pipe is installed on the lower side wall of the filter tank, and a disassembly cover is connected to the fixed pipe by fastening bolts. A sludge pump and a telescopic rod are installed on the outer end of the disassembly cover. A telescopic hose is connected to the inner end of the sludge pump. The telescopic hose extends into the activated carbon filter layer. A connection nozzle is provided on the outer end of the sludge pump. The telescopic hose is extended and retracted by the telescopic rod. The telescopic hose moves within the activated carbon filter layer. The activated carbon in the activated carbon filter layer is extracted by the sludge pump. The disassembly cover is removed and the activated carbon in the activated carbon filter layer is replenished through the fixed pipe, thereby realizing the replacement operation.

[0009] As a preferred embodiment of this application, the fixed tube is sealed and fixed on the filter tank, and the outer end of the fixed tube is provided with a connecting flange. The fastening bolt passes through the round hole on the disassembly cover, and the connecting flange is fitted with a nut. A sealing ring is provided at the connection between the disassembly cover and the fixed tube.

[0010] As a preferred embodiment of this application, the sludge pump is fixed to the disassembly cover by bolts, the connector of the sludge pump passes through the disassembly cover and is connected to the telescopic hose by connecting flange, bolts and nuts, and a sealing ring is provided at the connection between the connector of the sludge pump and the telescopic hose, and a sealing ring is provided at the connection between the connector of the sludge pump and the disassembly cover.

[0011] As a preferred embodiment of this application, the connecting nozzle is connected to the sludge pump via a thread, and a sealing ring is provided at the connection between the connecting nozzle and the sludge pump;

[0012] As a preferred embodiment of this application, the telescopic rod is a rigid round rod, and there is a mechanical seal between the telescopic rod and the disassembly cover. The inner end of the telescopic rod is connected to the telescopic hose by a clamp, and the telescopic rod drives the telescopic hose to change its length when it extends or retracts.

[0013] As a preferred embodiment of this application, the activated carbon filter layer is provided with an arc-shaped filter screen at the fixed tube, which restricts excessive flow of the activated carbon filter layer, and the telescopic hose passes through the arc-shaped filter screen.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By cleverly combining the use of a telescopic hose and a sludge pump, operators can easily access the interior of the activated carbon filter layer. This combination enables complete replacement of the activated carbon, ensuring the filter maintains its high filtration efficiency. This process not only improves filtration effectiveness but also extends the filter's lifespan.

[0016] Meanwhile, thanks to the carefully designed disassembly cap and fixing tube structure, the entire activated carbon replacement process becomes more convenient and faster. Users can easily perform installation and disassembly operations, significantly reducing the time and labor intensity required for activated carbon replacement. Due to the simplified replacement process, maintenance work becomes more efficient, thereby greatly reducing the time and labor costs required for maintenance. In this way, overall maintenance costs are effectively controlled.

[0017] During activated carbon replacement, multiple sealing measures, including sealing rings and mechanical seals, were employed to ensure the filter's sealing performance. These measures effectively prevented liquid or gas leakage during replacement, ensuring operational safety and stable filter operation. Through these detailed considerations and designs, the overall performance and reliability of the filter were further improved. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 - Figure 4 As shown, an activated carbon filter that facilitates activated carbon replacement comprises a robust support 1, a filter canister 2 for containing activated carbon, a sealing cap 3, and pipes 4. The filter canister 2 is cleverly mounted on the support 1 to ensure its stability and reliability. The sealing cap 3 is securely attached to the filter canister 2 via a locking device, ensuring the filter's sealing performance. Pipes 4 are installed on both the sealing cap 3 and the filter canister 2 to facilitate the entry and exit of liquids or gases.

[0025] An activated carbon filter layer 5 is installed inside the filter tank 2. This filter layer is confined within the filter tank 2 by a filter screen, thus ensuring that the activated carbon does not leak to the outside of the filter. The activated carbon filter layer 5 is a key component for achieving the filtration operation, effectively removing impurities and harmful substances from liquids or gases.

[0026] To facilitate activated carbon replacement, a fixing pipe 6 is specially installed on the lower side wall of the filter tank 2. The fixing pipe 6 is connected to a disassembly cover 7 by fastening bolts 8, allowing the disassembly cover 7 to be easily installed or removed. The outer end of the disassembly cover 7 is equipped with a sludge pump 9 and a telescopic rod 12. The inner end of the sludge pump 9 is connected to a telescopic hose 10, which can extend into the activated carbon filter layer 5. The outer end of the sludge pump 9 has a connecting nozzle 11. Driven by the telescopic rod 12, the telescopic hose 10 can freely extend and retract within the activated carbon filter layer 5. In this way, the activated carbon in the activated carbon filter layer 5 can be easily extracted by the action of the sludge pump 9, thereby realizing the replacement operation.

[0027] The fixed pipe 6 is sealed and fixed to the filter tank 2. Its outer end is provided with a connecting flange. The fastening bolt 8 passes through the round hole on the disassembly cover 7, and a nut is fitted at the connecting flange to ensure a tight connection between the disassembly cover 7 and the fixed pipe 6. In order to prevent leakage, a sealing ring is also provided at the connection between the disassembly cover 7 and the fixed pipe 6.

[0028] The sludge pump 9 is bolted to the disassembly cover 7, and its connector passes through the disassembly cover 7 and is connected to the telescopic hose 10 via a connecting flange, bolts, and nuts. To ensure a tight seal, sealing rings are provided at the connection points between the sludge pump 9 and the telescopic hose 10, as well as at the connection points with the disassembly cover 7.

[0029] The connecting nozzle 11 is connected to the sludge pump 9 via threads, and a sealing ring is also provided at the connection between the connecting nozzle 11 and the sludge pump 9 to prevent leakage.

[0030] The telescopic rod 12 is a rigid round rod, and a mechanical seal is used between it and the disassembly cover 7 to ensure the sealing performance of the telescopic rod 12. The inner end of the telescopic rod 12 is connected to the telescopic hose 10 by a clamp, so that when the telescopic rod 12 extends or retracts, it can drive the telescopic hose 10 to change its length, thereby enabling in-depth operation of the activated carbon filter layer 5.

[0031] To prevent excessive flow of activated carbon in the activated carbon filter layer 5, an arc-shaped filter screen is specially installed at the location of the activated carbon filter layer 5 facing the fixed pipe 6. The telescopic hose 10 can pass smoothly through this arc-shaped filter screen, ensuring smooth filtration operation.

[0032] Operating procedure: The liquid or gas to be filtered is introduced into the filter through pipe 4. The liquid or gas is filtered through the activated carbon filter layer 5 inside the filter tank 2. The filtered liquid or gas flows out of the filter through pipe 4, completing the filtration process.

[0033] Activated carbon replacement procedure: Close the inlet and outlet valves 4 of the filter to stop the flow of liquid or gas. Remove the fastening bolts 8 on the fixing pipe 6 and remove the removal cover 7. Connect the connector 11 of the sludge pump 9 to the removal cover 7. Start the sludge pump 9, and extend the telescopic hose 10 into the activated carbon filter layer 5 via the telescopic rod 12. The sludge pump 9 will start working, drawing the activated carbon out through the telescopic hose 10 and discharging it outside the filter. Once the activated carbon has been completely extracted, turn off the sludge pump 9. Remove the telescopic hose 10 and the sludge pump 9, reinstall the removal cover 7 and tighten the bolts 8. After checking all connections to ensure there are no leaks, reopen the inlet and outlet valves 4 to restore the filter to operation.

[0034] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
