[0029] The specific embodiments of the present application will be described in further detail below in combination with the drawings and examples. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0030] Please refer to Figure 1 and Figure 2 , the present application provides a liquid tank type filter, which comprises a frame body 10, an air volume adjusting assembly 30 and a detection assembly 50.

[0031] Specifically, the frame body 10 has a first direction, a second direction and a third direction perpendicular to each other, the inside of the frame body 10 is provided with a containing cavity 10a for mounting filter material 20, and the frame body 10 has an air inlet and an air outlet oppositely arranged and communicating with the containing cavity 10a. The air volume adjusting assembly 30 comprises a mounting beam 31, a flow distribution plate 32 and an adjusting rod 33, the mounting beam 31 is arranged in the containing cavity 10a along the first direction, and the two ends of the mounting beam 31 are connected with the frame body 10, the adjusting rod 33 penetrates through the mounting beam 31 and can move along the second direction, the flow distribution plate 32 is arranged on one side of the air inlet, the flow distribution plate 32 is connected with one end of the adjusting rod 33 close to the air inlet, and is used for guiding the air uniformly to the filter material 20. The detection assembly 50 comprises a sampling pipe 52 and a dust emission pipe 51, the sampling pipe 52 penetrates through the mounting beam 31 along the second direction to communicate the air inlet and the air outlet, and the dust emission pipe 51 penetrates through the mounting beam 31 along the second direction to communicate the air inlet and the air outlet.

[0032] Here, it should be noted that the "first direction", "second direction" and "third direction" mentioned above are virtual for the convenience of describing the positional relationship. Among them, in the present embodiment, the "first direction" refers to the width direction of the frame body 10, which can be specifically referred to the X direction in Figure 1 ; the "second direction" refers to the height direction of the frame body 10, which can be specifically referred to the Z direction in Figure 1 ; the "third direction" refers to the length direction of the frame body 10, which can be specifically referred to the Y direction in Figure 1 .

[0033] The application installs the filter material 20 in the receiving cavity 10a of the frame body 10, sets the mounting beam 31 in the receiving cavity 10a, then penetrates the mounting beam 31 with the adjusting rod 33, and connects the air diffuser plate 32 at one end of the adjusting rod 33 close to the air inlet, so that the air diffuser plate 32 is located on one side of the air inlet, and the adjusting rod 33 can move relative to the mounting beam 31 in the second direction, so that the air diffuser plate 32 is driven away from or close to the filter material 20 by the movement of the adjusting rod 33, thereby adjusting the air volume. Compared with the traditional adjusting mode using the adjusting valve, the structure is simpler, the adjustment is more convenient, the air volume can be adjusted in the room, and the uniformity of the air speed can be ensured under the action of the air diffuser plate 32, thereby providing better use experience.

[0034] In addition, when performing PAO detection, aerosol (a kind of substance simulating dust) can be directly injected to one side of the air inlet through the foaming pipe, and then the aerosol enters the room from the sampling pipe 52 under the action of the fan. At this time, whether the aerosol concentration reaches the specified value is detected by using the detection instrument located on one side of the air outlet. When the specified value is reached, detection is performed to determine whether the liquid tank type filter leaks. That is, the liquid tank type filter of the application can directly perform PAO detection without the need to install the filter material 20 in the traditional static pressure tank, and the structure is simple and convenient to detect.

[0035] Exemplarily, the mounting beam 31 is used to connect the frame body 10 in the liquid tank type filter, so that subsequent installation of the air diffuser plate 32 can be achieved. In order to ensure the installation strength during installation of the liquid tank type filter, the mounting beam 31 is made of aluminum alloy or other metal materials, but is not limited thereto.

[0036] Exemplarily, the dust generating pipe 51 and the sampling pipe 52 are penetrated on the mounting beam 31 in the second direction, so that aerosol can be directly injected from the dust generating pipe 51 to one side of the air inlet in the room, and the aerosol concentration reaching the specified value can be formed in the area between the liquid tank type filter and the mounting port. By placing the detection instrument at the port of the sampling pipe 52 located on one side of the air inlet, the aerosol concentration value can be detected to timely understand whether the aerosol concentration reaches the specified value that can start detection, so that PAO detection can be achieved without placing the filter material 20 in the static pressure tank. That is, the dust generating pipe 51 plays a role in injecting aerosol to one side of the air inlet, and the sampling pipe 52 plays a role in detecting whether the aerosol concentration on one side of the air inlet reaches the specified value.

[0037] Further, the air diffuser plate 32 has a plurality of air diffuser holes 32a, and the plurality of air diffuser holes 32a are arranged in an array. In this way, the air volume can be blown to the filter material 20 through the air diffuser holes 32a to ensure the uniformity of the air speed. Preferably, the shape of the air diffuser hole 32a is preferably circular, but is not limited thereto.

[0038] Please refer to Figure 2 and Figure 3 In an embodiment, the filter material 20 comprises a plurality of shaped skeletons 21, which are arranged in the accommodating cavity 10a in the third direction, and filter paper 22, which is arranged on each shaped skeleton 21. That is, by arranging a plurality of shaped skeletons 21 in the accommodating cavity 10a, and then arranging filter paper 22 on each shaped skeleton 21, the arrangement of filter paper 22 in the accommodating cavity 10a can be completed, and the structure is simple and convenient for replacing the filter paper 22. The shaped skeletons 21 are arranged to ensure that the filter paper 22 can maintain the corresponding folded state in any case, and the shape of the shaped skeletons 21 is the same as the shape of the cross section of the filter paper 22. The shaped skeletons 21 can be made of aluminum material to ensure that they are not damaged or deformed in a harsh transportation environment. In addition, the edges of the filter paper 22 need to be glued during production (the edges of the filter paper 22 in the prior art also need to be glued to ensure that air does not leak from the gap at the edges of the filter paper 22), and the shaped skeletons 21 can prevent the filter paper 22 from being deformed during gluing, thereby reducing the yield.

[0039] It should be noted that the "plurality" mentioned in the embodiment refers to two or more, which needs to be set according to the size of the accommodating cavity 10a, so as to ensure that enough filter paper 22 can be arranged in the accommodating cavity 10a to filter air.

[0040] In an embodiment, a protective net 40 is arranged at the air inlet and / or the air outlet.

[0041] It should be noted that "and / or" mentioned herein only describes the association relationship of the associated objects, and indicates that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in the present application generally indicates that the front and rear associated objects are in an "or" relationship. In the embodiment, the protective net 40 is arranged at the air inlet and the air outlet to protect the filter paper 22 by using the protective net 40, so as to avoid that foreign matter from the outside directly acts on the filter paper 22, thereby causing damage to the filter paper 22.

[0042] Please refer to Figure 4 and Figure 5 In an embodiment, the air volume adjusting assembly 30 further comprises a hollow guide pipe, which penetrates the mounting beam 31 in the second direction and is located between the sampling pipe 52 and the dust generating pipe 51, and the inner wall of the guide pipe is provided with a first transmission part. The adjusting rod 33 penetrates the guide pipe, and the rod body of the adjusting rod 33 is provided with a second transmission part which is in transmission connection with the first transmission part.

[0043] It should be noted that the first transmission part and the second transmission part can adopt a threaded transmission mode, that is, the adjusting rod 33 adopts a screw rod, and the inside of the guide pipe is provided with an internal thread, so that when the adjusting rod 33 is driven to rotate, the adjusting rod 33 can move relative to the guide pipe in the second direction, thereby driving the air diffuser plate 32 to approach or move away from the filter material 20. For example, when it is necessary to increase the amount of air entering the room, the adjusting rod 33 is driven to rotate (for example, reverse rotation), so that the adjusting rod 33 can move downward relative to the guide pipe in the second direction, thereby driving the air diffuser plate 32 to approach the filter material 20 and move away from the air source, so that more air is blown to the filter material 20, thereby allowing more air to be blown into the room; when it is necessary to reduce the amount of air entering the room, the adjusting rod 33 is driven to rotate (for example, forward rotation), so that the adjusting rod 33 moves upward relative to the guide pipe in the second direction, thereby driving the air diffuser plate 32 to move away from the filter material 20 and approach the air source, so that the air blown by the air source is partially blocked by the air diffuser plate 32 and reduced to blow to the filter material 20, thereby reducing the amount of air blown into the room.

[0044] In an embodiment, an adjusting opening 33a is formed at one end of the adjusting rod 33 close to the air outlet. The adjusting opening 33a can be a slit or a cross-shaped notch, as long as it can be driven to rotate by an auxiliary device. In actual application, when it is necessary to adjust the position of the air diffuser plate 32 to regulate the air volume, a flathead screwdriver is inserted from the bottom of the guide pipe so that the flathead screwdriver is inserted into the adjusting opening 33a, and then the flathead screwdriver is twisted to drive the adjusting rod 33 to rotate, so that the adjusting rod 33 can move relative to the guide pipe in the second direction, thereby driving the air diffuser plate 32 to move. That is, the adjusting opening 33a formed on the adjusting rod 33 is to facilitate personnel to twist the adjusting rod by a screwdriver, so as to control the movement of the adjusting rod 33.

[0045] In actual application, in order to avoid the air diffuser plate 32 being tightly attached to the mounting beam 31 when moving downward in the second direction, so that the air diffuser plate 32 cannot function, the position of the air diffuser plate 32 moving downward is usually limited. In an embodiment, the air volume adjusting assembly 30 further comprises a limiting frame 35 fixed to one end of the mounting beam 31 close to the air diffuser plate 32, the air diffuser plate 32 is located outside the limiting frame 35, and one end of the adjusting rod extending from the guide pipe passes through the limiting frame 35 and is connected with the air diffuser plate 32. That is, the limiting frame 35 fixed to one end of the mounting beam 31 close to the air diffuser plate 32 is used to limit the position of the air diffuser plate 32 moving downward, which can effectively avoid the air diffuser plate 32 being tightly attached to the mounting beam 31, and ensure that the air volume can be blown to the filter material 20 after being affected by the air diffuser plate 32.

[0046] In an embodiment, the sampling pipe 52 and / or the dusting pipe 51 is provided with sealing glue at the contact with the mounting beam 31. In practical application, there is a gap between the sampling pipe 52 and / or the dusting pipe 51 and the mounting beam 31, and if not handled, the air flow will leak from the gap, which will cause the aerosol concentration to fail to reach the specified value, and affect the accuracy of the detection. Therefore, in the embodiment, the sealing glue is provided at the contact between the sampling pipe 52 and the dusting pipe 51 and the mounting beam 31 to achieve the sealing effect and prevent the air flow from leaking.

[0047] In an embodiment, a sealing member is further included, which is detachably connected to one end of the sampling pipe 52 and the dusting pipe 51 close to the air outlet. In this way, it can be ensured that when the PAO detection is not performed, the unfiltered air will not enter the sampling pipe 52 or the dusting pipe 51, and the filtering efficiency can be improved.

[0048] In an embodiment, the surface of the mounting beam 31 on the side of the air outlet is flush with the surface of the frame body 10. In this way, it can be ensured that dust is not easy to accumulate during use, and cleaning can be facilitated.

[0049] The above description is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should be considered as the protection scope of the present application.
