[0021] A filter element 3 is arranged in the housing 1 (as shown in the figure, the filter element 3 is oriented vertically). When the filter element 3 reaches the end of its service life, it needs to be replaced; or it needs to be removed for cleaning, under the premise of ensuring the cleaning strength;

[0022] The housing 1 is provided with a rotating drive assembly 4, the closed cover 2 is integrally mounted with a rotated assembly 5, and the filter element 3 is sealed and stably located between the rotating drive assembly 4 and the rotated assembly 5 (i.e., the filter element 3 is contacted and pressed between the rotating drive assembly 4 and the rotated assembly 5);

[0023] The rotating drive component 4 drives the filter element 3 to rotate through the rotated component 5, and the filter element 3 is driven to rotate as a whole (under the condition that the rotation function of the entire filter element 3 is ensured, only the closing cover 2 needs to be removed to remove the rotated component 5 as a whole, and the filter element 3 can be taken out for easy replacement);

[0024] In order to realize the implementation and use of the above-mentioned rotary drive assembly 4, it is proposed that Figure 1 As shown, the specific structure and composition of the rotary drive assembly 4 can be as follows: the rotary drive assembly 4 includes a first sealing rotating member 41 (the first sealing rotating member 41 can be a mechanical sealing member, etc., providing a rotary sealing function) fixedly inserted into the housing 1 (as shown in the figure, the first sealing rotating member 41 penetrates into the interior of the housing 1 at the bottom end thereof);

[0025] A rotating shaft 42 is fitted and rotated in the first sealing rotating member 41, and one end of the rotating shaft 42 exposed outside the housing 1 is fixedly connected to the output shaft of a rotating driver 43 (which can be a servo motor, etc.), and the rotating driver 43 is operated to drive the rotating shaft 42 to rotate in the first sealing rotating member 41;

[0027] In order to realize the implementation and use of the above-mentioned transferred component 5, it is proposed that Figure 1 As shown, the specific structure and composition of the rotated component 5 can be as follows: the rotated component 5 includes a second sealing rotating member 51 (the second sealing rotating member 51 can be a mechanical sealing member, etc., providing a rotating sealing function) which is fixedly penetrated through the closed cover 2 and communicated with the housing 1 (as shown in the figure, the second sealing rotating member 51 penetrates into the housing 1 at the top end of the closed cover 2);

[0028] A rotating tube 52 is fitted and rotated in the second sealing rotating member 51, and an upper clamping plate 53 is fixedly connected to the side of the rotating tube 52 facing the lower clamping plate 45 and fits with the closing cover 2 (as shown in the figure, the bottom end of the rotating tube 52 is fixed to the upper clamping plate 53, and the top end of the upper clamping plate 53 fits and supports the bottom end of the closing cover 2);

[0029] The upper clamping plate 53 and the lower clamping plate 45 are sealed and fitted to stabilize the filter element 3 (the upper and lower ends of the filter element 3 are supported by the upper clamping plate 53 and the lower clamping plate 45, and the specific structure is as shown in the figure. Blocks are respectively provided at the top and bottom ends of the filter element 3, and the upper clamping plate 53 and the lower clamping plate 45 are respectively provided with grooves for the embedded blocks, and the outer side surface of the filter element 3 is fitted with the upper clamping plate 53 and the lower clamping plate 45, and the fitting position is pressed by a sealing layer, which can be a rubber layer, etc.).

[0030] Among them, the outer side of the shell 1 is fixedly provided with a liquid outlet pipe 8 connected with the inside thereof for discharging liquid (a switch valve is installed between the flow paths or at the end thereof, which may be an automatic electric valve, not shown in the figure, for opening and closing the liquid outlet pipe 8 for flow and cut-off). Embodiment 2:

[0031] like Figure 1 As shown, the difference from Example 1 is that: it also includes a liquid passing component 6 for adding and discharging liquid into the filter element 3, which is provided between the closing cover 2 and the rotated component 5, and is used to discharge the liquid inside the filter element 3 and discharge the liquid into it.

[0032] In order to realize the implementation and use of the above-mentioned liquid passage component 6, it is proposed that Figure 1 As shown, the specific structure and composition of the liquid-passing component 6 can be as follows: the liquid-passing component 6 includes a third sealing rotating member 61 (the third sealing rotating member 61 can be a mechanical sealing member, etc., providing a rotating sealing function) fixedly penetrating the upper clamping plate 53 (as shown in the figure, the third sealing rotating member 61 penetrates into the interior of the filter element 3 at the top of the upper clamping plate 53);

[0033] A rotating disk 62 is fitted and rotated inside the third sealing rotating member 61, and a fixing rod 63 fixed to the closing cover 2 is fixed outside the rotating disk 62 to stabilize the position of the rotating disk 62 and provide support;

[0034] A liquid inlet pipe 64 and a sewage discharge pipe 65 are fixedly inserted into the rotating disk 62 and the rotating tube 52 (as shown in the figure, the liquid inlet pipe 64 and the sewage discharge pipe 65 are both inserted into the filter element 3);

[0035] As shown in the figure, the liquid inlet pipe 64 can be relatively short, and is used to discharge the liquid to be treated into the filter element 3, and a switch valve is installed between the flow of the liquid inlet pipe 64 outside the rotating disk 62 or at the end thereof, and the switch valve can be an automatic electric valve (not shown in the figure), and is used to open and close the flow of the liquid inlet pipe 64 and cut off;

[0036] As shown in the figure, the drain pipe 65 is relatively long. When the filter element 3 is oriented vertically as shown in the figure, the drain pipe 65 extends into a position close to the lower clamping plate 45, which can increase the amount of liquid in the filter element 3 to be extracted, and a switch valve and a pump are installed between the partial flow or at the end of the drain pipe 65 outside the rotating disk 62. The switch valve can be an automatic electric valve (not shown in the figure) for opening and closing the drain pipe 65 for flow and cutting off. Embodiment 3:

[0037] like Figure 1 As shown, the difference from Example 2 is that: it also includes a filtering assembly 7 installed on the shell 1 for generating a liquid impact force from the outside to the inside of the filter element 3. The generated force impacts the filter element 3, and the impurities filtered outward are reversely removed to the inside of the filter element 3, and the sewage inside the filter element 3 is pumped out using the above-mentioned sewage pipe 65.

[0038] In order to implement the above-mentioned flushing and filtering assembly 7, it is proposed that Figure 1 As shown, the specific structure and composition of the flushing and filtering assembly 7 can be as follows: the flushing and filtering assembly 7 includes a liquid pump 71 (water pump, etc.) fixedly mounted on the outside of the housing 1;

[0039] The extraction end and the discharge end of the liquid pump 71 are respectively fixedly connected with a suction pipe 72 and a discharge pipe 73 and both are fixedly inserted into the housing 1 (the water in the liquid pump 71 is pumped into the discharge pipe 73 through the suction pipe 72);

[0040] A switch valve may be installed between the suction pipe 72 and the discharge pipe 73 (to prevent the suction pump 71 from being soaked). The switch valve may be an automatic electric valve (not shown) for opening and closing the suction pipe 72 and the discharge pipe 73 for flow and cutoff;

[0041] A strip tube 74 is provided in the housing 1 and is fixedly connected to the housing 1 via a fixed block 75 (the strip tube 74 is fixed in the housing 1);

[0042] The strip tube 74 is provided with a communicating flow chamber 76 and a discharge chamber 77, and the discharge pipe 73 is connected to the flow chamber 76 and the discharge pipe 73 is fixed to the strip tube 74 (i.e., the water in the discharge pipe 73 enters the flow chamber 76 and the discharge chamber 77 in sequence);

[0043] A slit connecting the discharge chamber 77 and the outside of the tube 74 is provided on the side of the tube 74 facing the filter element 3 (according to the above, the water in the discharge chamber 77 is discharged through the slit, and the impact force of the discharge is directed toward the filter element 3, so that the impurities can be reversely discharged into the interior of the filter element 3).

[0044] Among them, the circulation chamber 76 and the discharge chamber 77 are both strip-shaped with one end thereof facing the closed cover 2 and the other end facing the side of the shell body 1 opposite to the closed cover 2. The strip slit and the strip ends of the circulation chamber 76 and the discharge chamber 77 are oriented in the same direction (as shown in the figure, that is, the strip slit, the circulation chamber 76 and the discharge chamber 77 are all oriented up and down), which can form a strip-shaped water outlet impact, and perform overall impact cleaning on the above-mentioned rotating filter element 3 with high comprehensiveness.

[0045] The circulation chamber 76 and the discharge chamber 77 are connected via a strip-shaped opening identical to the strip end (when water flows from the circulation chamber 76 to the discharge chamber 77, the circulation balance is better) and (at the same time, when the liquid in the circulation chamber 76 is under a certain flow intensity, the overall flow volume from the strip opening to the discharge chamber 77 is balanced, and the liquid pump 71 is used to stabilize the intensity of water entering the circulation chamber 76).

[0046] For the above-mentioned Embodiment 1, Embodiment 2, and Embodiment 3, the backwashing cleaning process is as follows: the filter element 3 is backwashed by the filter flushing component 7, and the filter element 3 is rotated by the rotary drive component 4 and the rotated component 5 during the backwashing, and the impurities inside the filter element 3 are flushed back into the filter element 3 and mixed with the water inside it. At this time, they are discharged from the sewage pipe 65, and water is added from the liquid inlet pipe 64 at the same time. This process lasts for a period of time, that is, the filter element 3 is automatically cleaned.

[0047] For the above-mentioned embodiment 1, embodiment 2, and embodiment 3, a controller (not shown in the figure, which may be a PLC controller) is also included to supply power to the electrical components to control their opening and closing.

[0048] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.

[0049] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0050] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
