Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a multi-stage activated carbon uniform filter. Background Technology

[0002] Multi-stage activated carbon filters are integrated purification devices that combine pretreatment filtration and deep adsorption by activated carbon. They are primarily used to remove impurities, odors, and harmful pollutants, and are widely used in drinking water treatment, industrial wastewater purification, and air deodorization.

[0003] The existing patent with technical announcement number CN202315460U discloses a multi-stage filter, which is composed of a main tank, inlet, outlet, backwash inlet, backwash drain outlet, drain outlet, butterfly valve, endoscope and manhole, pipe fittings, discharge port, aeration port, stainless steel wedge filter layer, quartz sand filter layer, and activated carbon filter layer. The exterior of the main tank is fastened with a ring-shaped pipe fitting by flange bolts, and several check valves are connected in series and fixed to its right side. A shut-off valve is set at the lower left end of the pipe fitting. An endoscope and manhole are set at the upper left corner of the main tank. The interior of the main tank, from top to bottom, consists of a stainless steel wedge filter layer, a quartz sand filter layer, an activated carbon filter layer, a butterfly valve, a backwash drain outlet and inlet, an outlet and backwash inlet, and a drain outlet. The discharge port is located on the lower left side of the main tank. This utility model has the advantages of reasonable structure and large space, no leakage, internal and external corrosion protection and no pollution, convenient use, easy maintenance, and large filtration area.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Activated carbon in filters is usually fixedly piled up in the filter chamber. Affected by gravity and water flow direction, there is a serious problem of uneven use of activated carbon between the upper and lower layers. The upper activated carbon preferentially contacts the incoming water and preferentially adsorbs pollutants such as residual chlorine and organic matter in the water. It is under high load for a long time and is prone to rapid saturation and failure. Meanwhile, the lower activated carbon is idle because the pollutant concentration decreases after the water flows through the upper layer and its adsorption effect is not fully utilized. This unevenness will cause the overall filtration effect to decline prematurely, forcing users to replace the entire filter element in advance. This not only wastes activated carbon material, but also increases the frequency and cost of filter element replacement, and reduces the operating economy and continuous stability of the filtration system. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantages of short-flow phenomenon when the activated carbon is statically filled, resulting in uneven adsorption, low filter element utilization, short replacement cycle and high use cost. To this end, we propose a multi-stage filtration type activated carbon uniform filter.

[0006] To achieve the above objectives, this application adopts the following technical solution: a multi-stage filtration type activated carbon uniform filter, comprising a filter chamber rotating shaft, an inlet rotating shaft at the top of the filter chamber rotating shaft, an outlet rotating shaft on one side of the bottom of the filter chamber rotating shaft, and a suction rotating shaft on one side of the bottom of the filter chamber rotating shaft, the suction rotating shaft being connected to a water pipe rotating shaft, and a water pump rotating shaft installed on the water pipe rotating shaft near the suction rotating shaft, the filter chamber rotating shaft including a housing rotating shaft, the interior of the housing rotating shaft being composed of quartz from top to bottom. The filter includes a sand filter layer shaft, an activated carbon filter layer shaft, a microfiltration membrane filter layer shaft, and a water filter tank shaft. The outlet shaft and the inlet shaft are both located on the side wall of the water filter tank shaft. The activated carbon filter layer shaft includes a housing shaft, which is installed in the middle of the filter chamber shaft. It is connected to a water pipe shaft on one side above the housing shaft and the other side below the housing shaft. A shaft is installed in the center of the housing shaft, and a partition shaft is installed on the outer ring of the shaft. The partition shaft fits against the inner wall of the housing shaft, and the chamber of the partition shaft is filled with activated carbon.

[0007] Preferably, the height of the water intake shaft is lower than the height of the water outlet shaft.

[0008] Preferably, the rotating shaft is rotatably connected to the inner wall of the quartz sand filter layer.

[0009] Preferably, the partition shaft is provided with a perforated shaft.

[0010] Preferably, a rotating plate shaft is provided near one edge of the housing shaft. The rotating plate shaft is mounted on the shaft and is respectively installed between adjacent partition shafts.

[0011] Preferably, the rotating shaft of the rotating plate is inclined in a fan-blade shape.

[0012] The technical effects and advantages of this utility model are as follows: In this invention, a central rotating baffle structure is used to achieve uniform distribution and dynamic replacement of activated carbon adsorption units, thereby optimizing adsorption efficiency. A horizontal cylindrical shell is used as the activated carbon carrier, with its inner wall and the central rotating baffle forming intervals, dividing the internal space into multiple independent activated carbon-filled chambers. This ensures consistent activated carbon loading and distribution in each unit. When the rotating shaft drives the baffle to rotate, each filling chamber alternately enters the flow field regions at the inlet and outlet along a circular trajectory. This allows the lower activated carbon units, which were originally in a low-flow-rate region due to static accumulation, to periodically replace themselves with the higher-concentration influent side, while the upper units with a higher risk of saturation are transferred to the outlet side to complete residual adsorption. This dynamic replacement mechanism effectively eliminates the adsorption load differences caused by gravity and uneven flow field distribution in static filtration, significantly improving the overall utilization rate of the activated carbon bed and extending the effective service life of the filter element.

[0013] This invention utilizes a dual-pipe water outlet impact rotating plate structure to achieve water-driven rotation without external power, thus reducing energy consumption and maintenance costs. The rotating plate assembly adopts a fan-blade-like structure, coaxially fixed on the rotating shaft of the central rotating partition, and evenly distributed in the gaps between adjacent partitions to form multiple sets of water-driven units. Water pipes on both sides are connected to the inlet and outlet of the water pump, with their ports oriented to the rotating plate blades to form a directional jet channel. When the water pump starts, water flows through the water pipes on both sides to form a high-pressure jet, impacting the rotating plate blades to generate torque, driving the rotating shaft to rotate the partitions synchronously. Using the filtration system's own water energy as a power source, there is no need for additional motors, reducers, or other drive devices. This not only reduces the energy consumption of equipment manufacturing and operation but also reduces maintenance needs due to mechanical transmission component failures. At the same time, the jet drive method has the characteristics of rapid response and stable power output, and can automatically adjust the rotation speed according to the water pump flow rate to ensure that the activated carbon replacement frequency matches the treatment load.

[0016] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0017] Reference Figure 1 As shown, this utility model provides a technical solution: a multi-stage filtration type activated carbon uniform filter, including: a filter chamber 1, an inlet 2 fixedly installed at the top of the filter chamber 1, an outlet 3 installed on one side of the bottom of the filter chamber 1 for discharging filtered water, an intake 4 installed on one side of the bottom of the filter chamber 1, the position of the intake 4 being lower than the position of the outlet 3, a water pipe 6 being connected to the intake 4 through a flange, the water pipe 6 being connected to the middle of the filter chamber 1, and a water pump 5 being fixedly installed on the water pipe 6 near the intake 4, which can draw the filtered water in the filter chamber 1.

[0018] Reference Figure 2 As shown in this embodiment: the filter chamber 1 includes an outer shell 11, and inside the outer shell 11, from top to bottom, are a quartz sand filter layer 12, an activated carbon filter layer 13, a microfiltration membrane filter layer 14, and a water filter tank 15. The purpose of the quartz sand filter layer 12 is to remove large particles and avoid clogging the subsequent precision filter pores. The activated carbon filter layer 13 is used to remove organic matter and residual chlorine and adsorb impurities. The microfiltration membrane filter layer 14 is used to intercept small impurities to improve water quality. The outlet 3 and the inlet 4 are both located on the side wall of the water filter tank 15. One end of the water pipe 6 is connected to the inlet 4, and the other end of the water pipe 6 is connected to the side wall of the activated carbon filter layer 13.

[0019] Reference Figures 3-5As shown, in this embodiment: the activated carbon filter layer 13 includes a shell 131, the inner wall of which is cylindrical, and the shell 131 is provided with perforations, allowing water to be treated to pass through freely. The shell 131 is fixed in the middle of the filter chamber 1. A rotating shaft 132 is rotatably mounted at the center of the shell 131. The rotating shaft 132 is rotatably connected to the inner wall of the quartz sand filter layer 12. A partition 133 is fixedly mounted on the outer ring of the rotating shaft 132. The partition 133 fits against the inner wall of the shell 131, dividing the internal space of the shell 131 into multiple parts. The chamber of the partition 133 is filled with activated carbon. The partition 133 is provided with perforations 135. A rotating plate 134 is provided near one edge of the shell 131, and the rotating plate 134 is similar to a fan blade tilting. The rotating plate 134 is fixed on the rotating shaft 132 and installed between adjacent partitions 133. Water pipes 6 are connected to the upper side and the lower side of the housing 131 respectively. When water is drawn up by the water pump 5, it is sprayed onto the surface of the rotating plate 134 from the outlets of the water pipes 6 on both sides, which can drive the rotating shaft 132 to rotate, thereby driving the partitions 133 to rotate. This causes the activated carbon in each partition 133 chamber to rotate, realizing the exchange of upper and lower positions, and thus achieving uniform filtration. A timer can be connected to the water pump 5 to control the start and stop of the water pump 5 at regular intervals. For example, it can be set to rotate once a day, each time rotating 1 / 4 turn, and the activated carbon is replaced every 4 days, so that the upper and lower layers of activated carbon in the partition 133 chamber are fully utilized.

[0020] Working principle: During use, the water to be filtered enters from the inlet 2 at the top of the filter chamber 1, first flowing through the upper quartz sand filter layer 12. The gaps between the quartz sand particles intercept large impurities such as silt and rust in the water, preventing clogging of the pores of the subsequent precision filter layer. The pre-treated water flows through the activated carbon filter layer 13, allowing water to enter the interior through the perforations on the housing 131, where it fully contacts the activated carbon filled in the chambers divided by the partition 133. The porous structure of the activated carbon adsorbs pollutants such as organic matter and residual chlorine in the water. Simultaneously, the user can set the operating cycle via an external timer connected to the water pump 5, such as once a day. When the timer starts the water pump 5, the pump 5 draws filtered water from the low-level suction port 4 of the filter tank 15 and flows it through the water pipe 6. The water is delivered to the upper and lower interfaces of the housing 131. After the water is sprayed out from the interface, it impacts the tilted rotating plate 134, which drives the rotating shaft 132 and the partition plate 133 to rotate synchronously. Each rotation is 1 / 4 turn, which allows the activated carbon in each chamber to exchange positions, ensuring that the activated carbon originally at different heights can fully contact the water flow and avoid uneven utilization caused by static adsorption. The water flow treated by the activated carbon then passes through the lower microfiltration membrane filtration layer 14 to intercept small suspended solids, colloids and other impurities in the water. Finally, the purified water flows into the bottom water filter tank 15 and is discharged from the outlet 3, which is higher than the water inlet 4. After a 4-day cycle, the user can replace the activated carbon to complete the maintenance. The combination of graded filtration and dynamic adsorption achieves efficient and stable water purification.

[0021] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
