The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0061] During the use of the filter element, pollutants, dust and impurities in the sewage usually accumulate in the filter element, resulting in low filtration efficiency and continuous reduction of the filtration effect. Therefore, the staff needs to stop the machine regularly to replace the filter element to ensure the filtration effect and filtration efficiency. However, the replacement cycle of the filter element is different under different water qualities. If the staff fails to replace the filter element in time or replaces the filter element too early, it will lead to technical problems such as low filtration efficiency and poor purification effect. Therefore, there is a need for a method that can replace the filter element in time and reduce the frequency of filter element replacement to ensure the purification effect and filtration efficiency of the filter element to a certain extent.

[0062] In the present utility model, Figure 1 A schematic diagram of the structure of the filter element provided by the utility model; Figure 2 for Figure 1 See the exploded view of Figure 1 and Figure 2As shown, the filter element structure includes:

[0063] The replaceable filter element 100, the number of replaceable filter elements 100 is multiple, and the multiple replaceable filter elements 100 are arranged in a ring shape along the horizontal direction. The number of replaceable filter elements 100 can be selected according to the water quality conditions. For example, the number of replaceable filter elements 100 can be four, six, eight or more, and this is not specifically limited in the embodiments of the present utility model. The following embodiments are explained by taking the number of replaceable filter elements 100 as six as an example. The replaceable filter element 100 can generally adopt one or more of an activated carbon filter element, a filter mesh filter element, and a biofilm filter element, and the staff can select according to different water quality environments. Among them, activated carbon filter element: mainly used to remove odor and color from water, and can also remove harmful heavy metals, pesticide residues, drugs and other impurities in water; filter element: mainly used for pre-treatment of sewage or pre-filtration in the treatment process, and can filter out larger particles, such as sand, stones, branches, fish tails, etc.; organic matter removal filter element: such as biofilm filter element, ultrafiltration filter element, etc., mainly used to remove organic matter and colloid and other impurities in water, and can also remove viruses, bacteria and algae in water, so as to improve the safety of effluent water quality; inorganic salt removal filter element: such as reverse osmosis filter element, ion exchange filter element, etc., mainly used to remove inorganic salts and other ions in water, ultraviolet sterilization filter element: mainly used for disinfection and killing of bacteria in water, which can ensure the safety of effluent water quality.

[0064] A water inlet member 200, one end of which has a water inlet 210, and the other end of which has a plurality of water outlets 220 arranged in a ring shape, and the plurality of water outlets 220 are connected one-to-one with one end of a plurality of replaceable filter cartridges 100; in the same embodiment, the number of the water outlets 220 is generally equal to the number of the replaceable filter cartridges 100, for example, if the number of the replaceable filter cartridges 100 is six, then the number of the water outlets 220 is six, and each replaceable filter cartridge 100 is installed on the water outlet 220 corresponding thereto.

[0065] The water outlet part 300 has one end connected to the other end of the multiple replaceable filter cartridges 100 away from the water inlet part 200; wherein the water inlet part 200, the replaceable filter cartridge 100 and the water outlet part 300 are sequentially connected to form a filtering channel, and the sewage can be purified and filtered after passing through the water inlet part 200, the replaceable filter cartridge 100 and the water outlet part 300 in sequence. In addition, since the number of replaceable filter cartridges 100 can be set to multiple, the number of filtering channels can also be set to multiple.

[0066] A first detection member 400, which is disposed at one end of the water inlet member 200 away from the plurality of replaceable filter cartridges 100;

[0067] A second detection member 500, which is disposed at the other end of the water outlet member 300 away from the plurality of replaceable filter cartridges 100;

[0068] Among them, the first detection component 400 and the second detection component 500 can be flow meters or pressure sensors. The first detection component 400 is used to detect the flow rate of sewage at the water inlet 210 of the water inlet component 200; the second detection component 500 is used to detect the flow rate of water discharged from the water outlet component 300; the first detection component 400 and the second detection component 500 can be selected according to different sewage treatment requirements. For example: when the replaceable filter element 100 is selected as an activated carbon filter element or a filter mesh filter element, more impurities are filtered. The first detection component 400 and the second detection component 500 can be selected as an equalizing orifice plate detection component, a differential pressure detection component, a fluid velocimeter, etc. This type of detection component mainly measures the flow rate by measuring the pressure difference in the pipeline, so as to achieve precision control. When the replaceable filter element 100 is a filter element for removing organic matter, a filter element with higher precision is used, such as an ultrasonic detection component.

[0069] A switching component 600, the switching component 600 is connected to the water inlet 200, and the switching component 600 is suitable for controlling the water inlet 210 to selectively connect with any one of the multiple water outlets 220; a controller 700, the controller 700 is connected to the water inlet 200, and the controller 700 is electrically connected to the switching component 600, the first detection component 400 and the second detection component 500 respectively.

[0070] The controller 700 receives the detection information of the first detection component 400 and the second detection component 500, thereby calculating the difference between the detection information of the first detection component 400 and the second detection component 500, and monitors in real time whether the difference reaches a threshold. If the difference reaches the threshold, the controller 700 starts the switching component 600 to complete the switching of the replaceable filter element 100.

[0071] Through the above structure, the water inlet 200, the replaceable filter element 100 and the water outlet 300 form a filtering channel. When the sewage passes through the filtering channel, the filtering and purification function can be completed. At the same time, a first detection member 400 is set on the water inlet 200, and a second detection member 500 is set on the water outlet 300. Through the above structure, the flow rate of the water inlet 200 and the water outlet 300 within a certain period of time can be known. When the use time of the replacement filter element exceeds a certain time, the flow of sewage is restricted inside the filter element, so that the flow rate of the first detection member 400 and the second detection member 500 has a certain difference. Therefore, the use status of the replaceable filter element 100 can be known through the readings of the first detection member 400 and the second detection member 500; the water inlet 200 is provided with a plurality of water outlets 220, and a detection member 500 is installed on each water outlet 220. A replaceable filter element 100 is installed, so that multiple filtering channels are formed between the water inlet part 200, the replaceable filter element 100 and the water outlet part 300. The switching component 600 can realize the function of switching the filter element by switching the filtering channels. At the same time, the controller 700 is electrically connected to the switching component 600, the first detection component 400 and the second detection component 500, so that the controller 700 can start the switching component 600 according to the data information of the first detection component 400 and the second detection component 500. Specifically, when the difference between the second detection component 500 and the first detection component 400 is greater than the set threshold value, the set threshold value can be understood as the difference between the inlet flow and the outlet flow of the replaceable filter element 100 when the replaceable filter element 100 needs to be replaced, and the switching component 600 is started, thereby realizing the function of timely replacing the replaceable filter element 100.

[0072] See also Figure 2 In some examples of the present utility model, the water inlet member 200 includes:

[0073] The shell 230 has a accommodating cavity 231 , the water inlet 210 is arranged at the top end of the shell 230 in the vertical direction and is communicated with the accommodating cavity 231 , and a plurality of water outlets 220 are arranged at the bottom end of the shell 230 in the vertical direction and are communicated with the accommodating cavity 231 respectively.

[0074] Specifically, the shell 230 is made of hard material to ensure the stability of the water inlet 210 and the water outlet 220. In some embodiments, the shape of the shell 230 can be constructed as a cylindrical cavity structure, with a water inlet 210 at the top of the cylindrical cavity and a water outlet 220 at the bottom of the cylindrical cavity. The water outlet 220 can correspond to the installation of a replaceable filter element 100. The sewage enters the shell 230 through the water inlet 210, flows through the shell 230, and then enters the water outlet 220, thereby passing through the replaceable filter element 100.

The other end of the transmission shaft 630 passes through the shell 230 and is transmission-connected to the driving mechanism 620. There are multiple transmission connection methods, including gear transmission, chain transmission or belt transmission. The staff can choose different transmission methods according to actual conditions. The driving mechanism 620 drives the switching piece 610 to rotate in the horizontal direction through the transmission shaft 630, so that the water inlet 210 is selectively connected to any one of the multiple water outlets 220 through the through hole 611.

[0079] Through the above structure, the controller 700 starts the driving device, and the driving device drives the transmission shaft 630 to start rotating, thereby causing the switching plate 610 connected to the transmission shaft 630 to rotate. During the rotation of the switching plate 610, the position of the through hole 611 can be continuously rotated. When the position of the through hole 611 rotates between different replaceable filter elements 100, the switching of the filter element channel is completed.
