[0039] Embodiment:

[0040] Referring to Figures 1-5 , the present embodiment provides a filter core aeration drying device, comprising a coiled pipe 1, an upper cover 2 and a lower cover 3.

[0041] Referring to Figure 1 , Figure 4 , Figure 5 , Figure 7 and Figure 8 , the upper cover 2 is covered on the lower cover 3, so that the upper cover 2 and the lower cover 3 are surrounded to form an aeration chamber 4. The upper cover 2 starts with an aeration hole 21, which penetrates the upper surface and the lower surface of the upper cover 2 at the same time, so that the aeration chamber 4 is connected to the upper surface of the upper cover 2 through the aeration hole 21. The coiled pipe 1 is tubular, and the middle of the coiled pipe 1 is provided with an air inlet chamber 11, which is connected to both ends of the coiled pipe 1. The coiled pipe 1 penetrates the upper cover 2, so that part of the side wall of the coiled pipe 1 is located in the aeration chamber 4, and the first aeration passage 12 is formed on the side wall of the coiled pipe 1 inside the aeration chamber 4. Correspondingly, the first aeration passage 12 is connected to the air inlet chamber 11 and the aeration chamber 4 at the same time.

[0042] The reel-shaped filter core to be dried is supported on the upper cover 2, and the winding pipe 1 is inserted into the reel-shaped filter core, and then air flow is introduced into the air inlet cavity 11 from the end of the winding pipe 1, the air flow enters the aeration cavity 4 along the first aeration passage 12, and then is divided into streams towards the upper cover 2 through different aeration holes 21. The divided air flow can enter the gap between adjacent windings of the reel-shaped filter core, so that the reel-shaped filter core can obtain the drying effect without spreading. The drying process of the reel-shaped filter core described above not only has simple steps, reduces the time consumption of the drying process, but also avoids the spreading process of the reel-shaped filter core, reduces the required floor area during drying of the reel-shaped filter core, thereby reducing the drying cost of the reel-shaped filter core.

[0043] Referring to Figure 1 , Figure 9 and Figure 10 , the upper cover 2 is provided with a first drainage hole 22, which is arranged in a spaced manner with the aeration hole 21. Correspondingly, the part of the reel-shaped filter core directly above the first drainage hole 22 is not effectively flushed by the air flow, and the moisture in other parts of the reel-shaped filter core will gradually concentrate directly above the first drainage hole 22, and then drop to the first drainage hole 22 under the action of gravity. The lower cover 3 is provided with a second drainage hole 31, and the first drainage hole 22 and the second drainage hole 31 are both communicated to the aeration cavity 4. The first drainage hole 22 and the second drainage hole 31 are arranged in a relative manner in the axial direction of the winding pipe 1, so that the water droplets dropped to the first drainage hole 22 can be dropped to the second drainage hole 31 through the aeration cavity 4 under the action of gravity, and finally discharged out of the aeration cavity 4, avoiding the accumulation of water droplets in the reel-shaped filter core and improving the drying speed of the reel-shaped filter core.

[0044] Referring to Figure 10 , in order to avoid the influence of the air flow in the aeration cavity 4 on the water droplets dropped to the second drainage hole 31, the filter core aeration drying device further comprises a first sealing ring 6, which is located in the aeration cavity 4. The upper cover 2 and the lower cover 3 are respectively attached to two sides of the first sealing ring 6, and the middle of the first sealing ring 6 is provided with a third drainage hole 61, and the first drainage hole 22, the third drainage hole 61 and the second drainage hole 31 are sequentially communicated. Thus, the first drainage hole 22, the third drainage hole 61 and the second drainage hole 31 form an independent water droplet dropping channel, so that the first sealing ring 6 can block the air flow in the aeration cavity 4, and the air flow is prevented from entering the water droplet dropping channel.

[0045] The first sealing ring 6 is provided with a fastening screw 62, which is screwed on the upper cover 2 and the lower cover 3 at the same time, so that the upper cover 2 and the lower cover 3 are fixedly connected. The fastening screw 62 fixes the first sealing ring 6 on the upper cover 2 and the lower cover 3, avoids horizontal movement of the first sealing ring 6 in the aeration cavity 4, and makes the first liquid discharge hole 22, the third liquid discharge hole 61 and the second liquid discharge hole 31 always keep aligned. The fastening screw 62 can generate sufficient pressure on the first sealing ring 6 for the upper cover 2 and the lower cover 3, effectively avoiding separation of the upper cover 2 and the lower cover 3 from the first sealing ring 6, and preventing the air flow in the aeration cavity 4 from entering the water droplet falling channel.

[0046] Referring to Figure 2 , Figures 4-6 , Figure 9 and Figure 10 , the winding pipe 1 of the embodiment not only penetrates the upper cover 2 but also penetrates the lower cover 3. Correspondingly, both ends of the air inlet cavity 11 are communicated to the outside of the aeration cavity 4. If the air flow is directly introduced from the lower end of the air inlet cavity 11, part of the air flow will inevitably flow to the upper end of the air inlet cavity 11, resulting in waste of air flow and reducing the drying efficiency of the drum-shaped filter core.

[0047] Therefore, the filter core aeration drying device of the embodiment further comprises an air inlet seat 5. The outer wall of the air inlet seat 5 is provided with a first air inlet 51 and a first air outlet 52, and the air inlet seat 5 is provided with a second aeration passage 53. The first air inlet 51 and the first air outlet 52 are respectively communicated to both ends of the second aeration passage 53. The air inlet seat 5 is arranged at the lower end of the air inlet cavity 11. The first air inlet 51 is located outside the winding pipe 1, and the first air outlet 52 is located in the air inlet cavity 11 and is communicated with the first aeration passage 12. The air flow can enter the second aeration passage 53 from the first air inlet 51, then reach the first air outlet 52 and enter the first aeration passage 12. The second aeration passage 53 guides the flow direction of the air flow, avoiding the air flow flowing from the lower end of the air inlet cavity 11 to the upper end of the air inlet cavity 11, thereby avoiding waste of air flow.

[0048] The first air inlet 51 needs to be connected with an air pipe. In order to reduce the exposure of the air pipe, the filter core aeration drying device further comprises a base plate 7. Referring to Figure 1 , Figure 2 and Figure 9 , the base plate 7 is provided with a avoiding hole 71, and the lower cover 3 is supported on the base plate 7, so that the first air inlet 51 is located in the avoiding hole 71. The base plate 7 is provided with an air pipe groove 72, and the avoiding hole 71 is communicated to the air pipe groove 72. The air pipe can be arranged in the air pipe groove 72, and the air pipe is shielded by the base plate 7. The end of the air pipe can reach the avoiding hole 71 under the guidance of the air pipe groove 72, so as to be connected with the first air inlet 51 in the avoiding hole 71.

[0049] The part of the air inlet seat 5 in the avoiding hole 71 is attached to the side wall of the avoiding hole 71, so that the air inlet seat 5 can be positioned on the base plate 7 to a certain extent, the air inlet seat 5 can be reduced to shake on the base plate 7 during air passage, so as to maintain the stability of the connection between the first air inlet 51 and the air pipe.

[0050] The operation gap 73 is arranged on the side of the base plate 7 away from the lower cover 3, and the operation gap 73 is located at the connection between the avoiding hole 71 and the air pipe groove 72. The operation gap 73 can be used to conveniently observe whether the first air inlet 51 is aligned with the end of the air pipe, and also can be used to conveniently disassemble and assemble the first air inlet 51 and the end of the air pipe.

[0051] Preferably, the side of the lower cover 3 away from the upper cover 2 is recessed towards the upper cover 2 to form a drainage groove 32, and the second drainage hole 31 is arranged on the side wall of the drainage groove 32, so that the second drainage hole 31 and the surface of the base plate 7 are arranged at intervals, so as to avoid that the base plate 7 blocks the second drainage hole 31. The water droplets falling at the second drainage hole 31 can flow to the edge of the base plate 7 through the drainage effect of the drainage groove 32, so as to avoid that the water droplets accumulate in the second drainage hole 31.

[0052] In order to avoid that the first screw hole 23 interferes with the support of the upper cover 2 to the filter element in the form of a roll, and also in order to avoid that the first screw hole 23 interferes with the support of the base plate 7 to the lower cover 3, referring to Figure 1 and Figure 9 the upper cover 2 is provided with the first screw hole 23, the lower cover 3 is provided with the second screw hole 33, and the two ends of the fastening screw 62 are located in the first screw hole 23 and the second screw hole 33, respectively.

[0053] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, it should be considered that it is within the scope of the description.

[0054] The above-mentioned embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, on the premise of not departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
