In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0035] like Figures 1 to 3 As shown, the technical solution of this embodiment is applied, and the filter assembly is arranged between the feed pipe 100 and the discharge pipe. The filter assembly includes: a first filter 10, a first valve body 20, a second valve body 30 and a first stop member 40. The first filter 10 has a first filter inlet and a first filter outlet, and the first filter outlet can be connected to the discharge pipe. The first filter 10 includes a first filter body 11 and a first cover body 12 detachably arranged on the first filter body 11. The first valve body 20 has a first feed position connecting the feed pipe 100 with the first filter inlet and a first cut-off position disconnecting the feed pipe 100 from the first filter inlet. The second valve body 30 is arranged on the first filter 10, and the second valve body 30 includes a first valve body 31 and a first handle 32 rotatably arranged on the first valve body 31. The first handle 32 rotates so that the second valve body 30 has a first conduction position connecting the first filter cavity of the first filter 10 with the drain pipe 200 and a first disconnection position disconnecting the first filter cavity from the drain pipe 200. The first stopper 40 is connected to the first handle 32. The first handle 32 rotates and drives the first stopper 40 to move, so that the first stopper 40 has a first stop position and a first avoidance position. When the first handle 32 is in the first disconnection position, the first stopper 40 is in the first stop position above the first cover body 12. When the first handle 32 is in the first conduction position, the first stopper 40 is in the first avoidance position on one side of the first cover body 12.

[0036] In this way, when the first handle 32 is in the first disconnected position, the first filter chamber is disconnected from the drain pipe 200, and there is pressure in the first filter chamber. At this time, since the first stop member 40 is in the first stop position, the first stop member 40 can stop above the first cover body 12 to prevent the operator from opening the cover. In this way, when there is pressure in the first filter chamber, the first stop member 40 can prevent the operator from opening the cover. The operator needs to turn the first handle 32 to the first conduction position to connect the first filter chamber with the drain pipe 200 to perform a pressure relief operation. When the first handle 32 is rotated to the first conduction position, the first stop member 40 can avoid the first cover body 12 to allow the operator to open the cover. In this way, by setting the first stopper 40 and the first handle 32, when there is pressure in the first filter 10, the first stopper 40 can prevent the cover from being opened; after the operator turns the first handle 32 to perform the pressure relief operation, the first stopper 40 can avoid opening the cover, so as to facilitate the cleaning operation of the first filter body 11. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the operator is easy to forget to perform the pressure relief operation, which is easy to cause the cover to pop open and injure people.

[0037] Furthermore, the first valve body 20 is provided to facilitate control of connection and disconnection between the feed pipe 100 and the first filter inlet, and the second valve body 30 is provided to facilitate connection and disconnection between the first filter cavity and the ground drain pipe 200 , so as to facilitate filtering and cleaning operations of the first filter 10 .

[0038] like Figures 1 to 3 As shown, the filter assembly also includes a first induction member 50 that is inductively matched with the first handle 32, and the first induction member 50 is connected to the first valve body 20 by signal. When the first handle 32 is in the first conduction position, the first induction member 50 sends a first stop signal to the first valve body 20, so that the first valve body 20 is in the first cut-off position. In this way, the first induction member 50 is arranged to cooperate with the first valve body 20, so that when the first handle 32 connects the first filter cavity with the drain pipe 200, the first valve body 20 can receive the first stop signal sent by the first induction member 50, so that the first valve body 20 disconnects the first filter inlet from the feed pipe 100. In this way, when the first filter cavity is connected with the drain pipe 200, the material in the feed pipe 100 is prevented from continuing to enter the first filter cavity through the first filter inlet, and the problem that the operator forgets to operate the first valve body 20 so that the material is discharged from the drain pipe 200 is avoided, thereby reducing the waste of materials.

[0039] In this embodiment, the first sensor 50 is connected to the feed system signal. When the first handle 32 is in the first on position, the first sensor 50 controls the first valve body 20 to be in the first off position through the feed system.

[0040] like Figures 1 to 3 As shown, the first stopper 40 includes a first connecting rod 41 fixedly connected to the first handle 32 and a first stopper rod 42 connected to the first connecting rod 41 at an angle, the first connecting rod 41 is located at one side of the first filter 10, and when the first stopper 40 is in the first stop position, the first stopper rod 42 is located above the first cover 12. When the first stopper 40 is in the first avoidance position, the first stopper rod 42 is located at one side of the first cover 12. In this way, the first connecting rod 41 is arranged at one side of the first filter 10, so that when the first handle 32 rotates, the first connecting rod 41 can be driven to rotate, thereby reducing the possibility of interference between the first connecting rod 41 and the first filter 10. The first stopper rod 42 is arranged at an angle to the first connecting rod 41, so that when the first connecting rod 41 rotates, the first stopper rod 42 can be driven to swing, so that the first stopper rod 42 can stop above the first cover 12, or the first stopper rod 42 can avoid the first cover 12.

[0041] In this embodiment, the first connecting rod 41 is vertically arranged with the first stopping rod 42. The first handle 32 is located at one side of the first filter body 11.

[0042] like Figures 1 to 3 As shown, the first stop rod 42 is a first straight rod. The first straight rod has a simple structure, which is convenient for processing the first stop member 40.

[0043] In other embodiments, the first stop rod 42 is a first curved rod. The provision of the first curved rod increases the area of ​​the first stop rod 42 on the first cover body 12, so that the operator can more easily see that the first stop member 40 is in the first stop position, so as to remind the operator not to open the cover at this time. The first curved rod includes an arc segment, or the first curved rod includes a plurality of arc segments connected in a first position.

[0044] like Figures 1 to 3As shown, the filter assembly also includes a second filter 60, which is spaced apart from the first filter 10. The second filter 60 has a second filter inlet and a second filter outlet, and the second filter outlet can be connected to the discharge pipe. The second filter 60 includes a second filter body 61 and a second cover body 62 detachably arranged on the second filter body 61. Among them, the first valve body 20 also has a second feed position connecting the feed pipe 100 and the second filter inlet and a second cut-off position disconnecting the feed pipe 100 and the second filter inlet. In this way, when the first filter 10 is cleaned, the material can be fed into the second filter 60 for filtering, which improves the filtering efficiency and reduces the downtime waiting time. When the first filter 10 is cleaned, the first valve body 20 is switched to the second feed position so that the material in the feed pipe 100 can enter the second filter 60, and the second filter outlet is set to facilitate the discharge of the filtered material. The second filter body 61 and the second cover body 62 are set to facilitate the cleaning of the second filter 60.

[0045] In this embodiment, the first feed position and the second cut-off position of the first valve body 20 are the same, and the second feed position and the first cut-off position of the first valve body 20 are the same, so that the material can be switched more quickly between the first filter 10 and the second filter 60, further improving the filtration efficiency.

[0046] like Figures 1 to 3As shown, the filter assembly also includes a third valve body 70 and a second stopper 80. The third valve body 70 is arranged on the second filter 60, and the third valve body 70 includes a second valve body 71 and a second handle 72 rotatably arranged on the second valve body 71. The second handle 72 rotates so that the third valve body 70 has a second conducting position for conducting the second filter cavity of the second filter 60 with the drain pipe 200 and a second disconnecting position for disconnecting the second filter cavity from the drain pipe 200. The second stopper 80 is connected to the second handle 72, and the second handle 72 rotates and drives the second stopper 80 to move, so that the second stopper 80 has a second stop position and a second avoidance position. When the second handle 72 is in the second disconnection position, the second stopper 80 is in the second stop position located above the second cover body 62. When the second handle 72 is in the second conducting position, the second stopper 80 is in the second avoidance position located on one side of the second cover body 62. In this way, when the second handle 72 is in the second disconnection position, the second filter chamber is disconnected from the drain pipe 200, and there is pressure in the second filter chamber. At this time, since the second stopper 80 is in the second stop position, the second stopper 80 can stop above the second cover 62 to prevent the operator from opening the cover. In this way, when there is pressure in the second filter chamber, the second stopper 80 can prevent the operator from opening the cover. The operator needs to turn the second handle 72 to the second conduction position to connect the second filter chamber with the drain pipe 200 to perform a pressure relief operation. When the second handle 72 is rotated to the second conduction position, the second stopper 80 can avoid the second cover 62 to allow the operator to open the cover. In this way, by setting the second stopper 80 and the second handle 72, when there is pressure in the second filter 60, the second stopper 80 can prevent the cover from opening; after the operator turns the second handle 72 to perform the pressure relief operation, the second stopper 80 can avoid opening the cover, so as to facilitate the cleaning operation of the second filter body 61. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the operator is easy to forget to perform the pressure relief operation, which is easy to cause the cover to pop open and injure people.

[0047] like Figures 1 to 3As shown, the filter assembly also includes a second sensor 90 that is inductively matched with the second handle 72, and the second sensor 90 is connected to the first valve body 20 by signal. When the second handle 72 is in the second conduction position, the second sensor 90 sends a second stop signal to the first valve body 20, so that the first valve body 20 is in the second cut-off position. In this way, the second sensor 90 is arranged to cooperate with the first valve body 20, so that when the second handle 72 connects the second filter cavity with the drain pipe 200, the first valve body 20 can receive the second stop signal sent by the second sensor 90, so that the first valve body 20 disconnects the second filter inlet from the feed pipe 100. In this way, when the second filter cavity is connected with the drain pipe 200, the material in the feed pipe 100 is prevented from continuing to enter the second filter cavity through the second filter inlet, and the problem that the operator forgets to operate the first valve body 20 so that the material is discharged from the drain pipe 200 is avoided, thereby reducing the waste of materials.

[0048] like Figures 1 to 3 As shown, the filter assembly further includes a first sensing member 50 that is inductively matched with the first handle 32, and the first sensing member 50 is connected to the first valve body 20 by signal. When the first handle 32 is in the first conduction position, the first sensing member 50 sends a first stop signal to the first valve body 20, so that the first valve body 20 is in the first cut-off position. The first sensing member 50 is a first proximity switch. When the distance between the first proximity switch and the first handle 32 is greater than the first sensing distance, the first handle 32 is in the first conduction position. When the distance between the first proximity switch and the first handle 32 is less than the first sensing distance, the first handle 32 is in the first cut-off position. The first proximity switch has a simple structure and is easy to process. The first proximity switch can effectively detect the position of the first handle 32, so that the first sensing member 50 detects the position of the first handle 32 more accurately. The second sensing member 90 is a second proximity switch. When the distance between the second proximity switch and the second handle 72 is greater than the second sensing distance, the second handle 72 is in the second conduction position. When the distance between the second proximity switch and the second handle 72 is less than the second sensing distance, the second handle 72 is in the second cut-off position. The second proximity switch has a simple structure and is easy to process. The second proximity switch can effectively detect the position of the second handle 72 , so that the second sensing element 90 can detect the position of the second handle 72 more accurately.

[0049] In other embodiments, the filter assembly further includes a first sensing member 50 that is inductively matched with the first handle 32, and the first sensing member 50 is connected to the first valve body 20 by signal. When the first handle 32 is in the first conduction position, the first sensing member 50 sends a first stop signal to the first valve body 20 to make the first valve body 20 in the first cut-off position. The first sensing member 50 is a first proximity switch, and when the distance between the first proximity switch and the first handle 32 is greater than the first sensing distance, the first handle 32 is in the first conduction position, and when the distance between the first proximity switch and the first handle 32 is less than the first sensing distance, the first handle 32 is in the first cut-off position. Alternatively, the second sensing member 90 is a second proximity switch, and when the distance between the second proximity switch and the second handle 72 is greater than the second sensing distance, the second handle 72 is in the second conduction position, and when the distance between the second proximity switch and the second handle 72 is less than the second sensing distance, the second handle 72 is in the second cut-off position.

[0050] like Figures 1 to 3 As shown, the second stopper 80 includes a second connecting rod 81 fixedly connected to the second handle 72 and a second stopper rod 82 connected to the second connecting rod 81 at an angle. The second connecting rod 81 is located at one side of the second filter 60, and when the second stopper 80 is in the second stop position, the second stopper rod 82 is located above the second cover 62. When the second stopper 80 is in the second avoidance position, the second stopper rod 82 is located at one side of the second cover 62. In this way, the second connecting rod 81 is arranged at one side of the second filter 60, so that when the second handle 72 rotates, the second connecting rod 81 can be driven to rotate, thereby reducing the possibility of interference between the second connecting rod 81 and the second filter 60. The second stopper rod 82 is arranged at an angle to the second connecting rod 81, so that when the second connecting rod 81 rotates, the second stopper rod 82 can be driven to swing, so that the second stopper rod 82 can stop above the second cover 62, or the second stopper rod 82 can avoid the second cover 62.

[0051] In this embodiment, the second connecting rod 81 is vertically arranged with the second stopping rod 82. The second handle 72 is located at one side of the second filter body 61.

[0052] like Figures 1 to 3 As shown, the second stop rod 82 is a second straight rod. The first straight rod has a simple structure, which is convenient for processing the first stop member 40.

[0053] In other embodiments, the second stop rod 82 is a second curved rod. The second curved rod increases the area of ​​the second stop rod 82 on the second cover body 62, so that the operator can more easily see that the second stop member 80 is in the second stop position, so as to remind the operator not to open the cover at this time. The second curved rod includes an arc segment, or the second curved rod includes a plurality of arc segments connected in a first position.

[0054] In this embodiment, the filter assembly is a wet-mixed duplex filter in the pre-processing section of the production workshop. A removable filter bag is arranged in the first filter 10, and the filter bag is taken out and replaced regularly.

[0055] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0056] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0057] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0058] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
