Description

Technical Field

[0001] This utility model relates to the field of activated carbon filtration technology, specifically to an activated carbon filtration device. Background Technology

[0002] In the field of water treatment, activated carbon filtration devices are widely used in scenarios such as pretreatment of domestic sewage and industrial wastewater, as well as deep purification of drinking water, because they can effectively adsorb organic matter, odors, and some impurities in wastewater. Currently, activated carbon filtration devices on the market typically consist of a filtration unit and an activated carbon holding unit, with the activated carbon holding unit being the core component for achieving secondary filtration of wastewater.

[0003] However, existing activated carbon filtration devices have certain shortcomings in actual use, with the core problem being the cumbersome operation of replacing activated carbon.

[0004] Existing activated carbon containment components often employ integrated welding or multiple bolt-fixed structures. When the activated carbon becomes saturated and needs replacement, operators must use wrenches, screwdrivers, and other tools to disassemble the fixing bolts or welded connections one by one. In some systems, the entire activated carbon containment unit even needs to be removed from the filtration system before the activated carbon can be emptied and refilled. This process is not only labor-intensive and time-consuming, but also involves complex procedures. Furthermore, the disassembly and installation process can easily damage the device's sealing structure, leading to wastewater leakage during subsequent filtration. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an activated carbon filtration device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An activated carbon filtration device includes: a filter tube, a control valve connector at the top of the filter tube, an inlet pipe on the left side of the control valve connector, a valve port on the right side of the control valve connector, a carbon box at the bottom of the filter tube, a circular threaded interface at the top of the carbon box, an internal thread on the bottom inner wall of the control valve connector, the circular threaded interface being used to achieve connection by rotating and engaging with the internal thread, a cuboid at the bottom of the carbon box, multiple sets of circular holes on each of the four side walls of the cuboid, a removable bottom layer fixedly installed at the bottom of the cuboid, the removable bottom layer being fixedly connected to the inner wall of the cuboid by a bent sheet metal part, the removable bottom layer being used to stack activated carbon and fill the carbon box, and a filter element installed inside the filter tube, the filter element being used for preliminary filtration of sewage, and the activated carbon being used for secondary filtration of sewage; Round holes one and two are used as outlets for filtered water. The inlet pipe is connected to the output pipe of the water pump to transport sewage to the filter pipe. The valve port is used to connect and fix with the butterfly valve, which is used to control the flow rate of sewage to the filter pipe.

[0007] Preferably, sealing rings are provided between the control valve connector and the filter tube, and between the circular threaded interface and the internal thread of the carbon box.

[0008] Preferably, a layer of fine stainless steel mesh is fixed to the upper surface of the removable bottom layer of the charcoal box. The stainless steel mesh is used to support the activated carbon and prevent it from leaking out from the round holes.

[0009] Compared with the prior art, the present invention provides an activated carbon filtration device with the following advantages: The rectangular structure at the bottom of the activated carbon box features a removable bottom layer, which is secured to the inner wall of the rectangular box by a bent sheet metal part. When it is necessary to replace the activated carbon, simply release the clamp between the bent sheet metal part and the inner wall to remove the removable bottom layer directly. There is no need to disassemble the connection structure between the activated carbon box and the filter tube, which allows for quick emptying of the saturated activated carbon in the activated carbon box and refilling with new activated carbon.

[0012] 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.

[0013] Reference Figure 1-3 As shown, an activated carbon filtration device in this embodiment includes a filter tube 1, which serves as the core carrier for the initial filtration of wastewater. A filter element is fixedly installed inside the filter tube, which can perform initial filtration of the incoming wastewater, intercepting larger particles of impurities in the wastewater, and laying the foundation for subsequent secondary filtration by activated carbon.

[0014] The top of the filter pipe 1 is integrally formed with a control valve connector 101. An inlet pipe 1012 is welded and fixed to the left side of the control valve connector 101. The inner diameter of the inlet pipe 1012 is adapted to the outer diameter of the water pump output pipe. By means of flange connection or hose clamp, the inlet pipe 1012 can be tightly connected to the water pump output pipe to ensure that the sewage can be stably transported to the filter pipe 1. A valve port 1011 is reserved on the right side of the control valve connector 101. The inner wall of the valve port 1011 is provided with internal threads, which can be directly screwed and fixed with the external threads of the butterfly valve. The butterfly valve can flexibly adjust the opening degree by rotating the valve plate, thereby accurately controlling the flow rate of sewage to the filter pipe 1, avoiding insufficient filtration due to excessive flow rate or affecting the treatment efficiency due to excessively slow flow rate.

[0015] A carbon box 2 is located below the filter tube 1. The top of the carbon box 2 is machined into a circular threaded interface. The outer diameter of the circular threaded interface matches the internal thread on the bottom inner wall of the control valve connector 101. By rotating the carbon box 2 clockwise, the circular threaded interface and the internal thread can be tightly fitted, realizing the quick assembly of the carbon box 2 and the filter tube 1. Conversely, rotating it counterclockwise can separate the two. This threaded connection method does not require additional tools, is convenient to operate, and has stable sealing performance.

[0016] The lower part of the carbon box 2 is a cuboid structure. Multiple sets of circular holes 201 are evenly distributed on all four side walls of the cuboid, ensuring smooth flow of filtered water while preventing leakage of activated carbon particles from the carbon box. A removable bottom layer 202 is located at the bottom of the cuboid. The edges of the removable bottom layer 202 are welded with bent sheet metal parts. The curvature of the bent sheet metal parts matches the curvature of the inner wall of the cuboid. By inserting the bent sheet metal parts into pre-set grooves on the inner wall of the cuboid, the removable bottom layer 202 and the cuboid can be clamped and fixed together. Multiple sets of circular holes 2021 are formed on the removable bottom layer 202. Its top is used to pile activated carbon and fill the carbon box 2. Wastewater that has undergone preliminary filtration through the filter pipe 1 flows into the carbon box 2, making full contact with the activated carbon. The activated carbon removes organic matter and odors from the wastewater through adsorption. Finally, the filtered water is discharged from both the first and second circular holes 201.

[0017] In some examples, nitrile rubber sealing rings are embedded at the connection between the control valve connector 101 and the filter pipe 1, and at the connection between the circular threaded interface of the carbon box 2 and the internal thread at the bottom of the control valve connector 101. Nitrile rubber has excellent oil resistance and sewage corrosion resistance, which can effectively fill the connection gap, prevent sewage from leaking from the connection during flow, reduce frictional wear between components, and extend the service life of the connection structure.

[0018] In some examples, the upper surface of the removable bottom layer 202 of the carbon box 2 is fixed with a layer of 80-mesh fine stainless steel mesh by spot welding. The 80-mesh mesh size can stably support the activated carbon particles without obstructing the flow of filtered clean water. At the same time, the stainless steel mesh has good tensile strength and corrosion resistance. Even if it is in contact with sewage and activated carbon for a long time, it is not easy to deform or be damaged, so there is no need to replace it frequently, reducing maintenance costs.

[0019] The working principle of this utility model is as follows: Before using this activated carbon filtration device, component assembly and debugging must be completed to ensure stable fit of each structure. First, according to the installation space of the wastewater treatment scenario, place the filter pipe 1 vertically. Check whether the internal thread on the bottom inner wall of the control valve connector 101 is clean. Then, align the circular threaded interface on the top of the carbon box 2 with the internal thread and rotate the carbon box 2 clockwise until it is tightened. At this time, the pre-embedded nitrile rubber sealing rings at the connection between the carbon box 2 and the control valve connector 101, as well as at the connection between the control valve connector 101 and the filter pipe 1, will be compacted, effectively filling the connection gap and preventing subsequent wastewater leakage. Next, align the bent sheet metal part on the edge of the removable bottom layer 202 with the preset slot on the inner wall of the cuboid of the carbon box 2, press and clamp it to achieve the clamping fixation of the bottom layer and the carbon box. Then, fill the carbon box 2 with activated carbon until the cuboid space is filled. At this time, the 80-mesh fine stainless steel mesh on the upper surface of the removable bottom layer will support the activated carbon and prevent activated carbon particles from leaking out from the circular hole 2021 of the bottom layer. Finally, install the filter element inside the filter tube 1 into place, then connect the inlet pipe 1012 to the water pump output pipe through a flange or hose clamp, and fix the valve port 1011 to the butterfly valve by screwing them together. After completing the overall assembly, start the water pump for a small flow test run, check whether there is any leakage at each connection part, whether the butterfly valve can adjust the flow rate normally, and ensure that the device is in a ready-to-work state.

[0020] When the device enters the normal filtration stage, the operator can start the water pump, and the wastewater is transported to the control valve connector 101 through the inlet pipe 1012. At this time, the opening can be adjusted by rotating the butterfly valve plate: if there are many impurities in the wastewater, the butterfly valve opening can be reduced to decrease the flow rate, allowing the wastewater sufficient time to contact the filter components in subsequent filtration stages; if it is necessary to improve the treatment efficiency, the flow rate can be increased while ensuring the filtration effect. The wastewater with controlled flow rate first enters the filter pipe 1, making full contact with the filter element inside the pipe. The filter element will intercept larger diameter impurities in the wastewater, completing the preliminary filtration and preventing large particles from entering the carbon box 2, clogging the gaps in the activated carbon, and affecting the adsorption effect.

[0021] After initial filtration, the wastewater flows downwards along the inner wall of filter pipe 1 and enters the rectangular space of activated carbon box 2, where it comes into full contact with the activated carbon inside. The activated carbon, with its porous structure, adsorbs organic matter, odor molecules, pigments, and some small-molecule impurities from the wastewater, achieving secondary filtration. During this process, the circular holes 201 on the four side walls of the rectangular box 2 and the circular hole 2021 on the removable bottom layer simultaneously serve as outlets. The filtered water flows naturally from these holes and into the subsequent clean water collection pipeline, completing the entire wastewater filtration process. Simultaneously, the epoxy resin anti-corrosion coating on the inner wall of activated carbon box 2 isolates the wastewater from direct contact with the metal inner wall, preventing corrosion and ensuring structural stability during long-term filtration.

[0022] When the activated carbon becomes saturated and needs replacement, the operator can simply hold the removable bottom layer 202 by hand and apply outward force to release the clamping engagement between the bent sheet metal part and the inner wall of the activated carbon box. The removable bottom layer 202 can then be removed directly, and the saturated old activated carbon inside the box can be emptied. New activated carbon is then refilled into the activated carbon box 2, and the bent sheet metal part of the removable bottom layer 202 is aligned with the clamping groove and tightened. The entire process can be completed in a few minutes by a single person without the need for tools, effectively avoiding the problems of cumbersome disassembly and long downtime associated with traditional devices.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
