[0028] Embodiment 1:

[0029] See also Figure 1 This embodiment provides a carbon rod filter element cleaning device, including a cover 1, a first air injection pipe 2, a plurality of first air suction pipes 3, an air tank 4 and an air pump 5.

[0030] The gas tank 4 is connected to the first jet pipe 2, the first suction pipe 3 is connected to the air pump 5, and the first jet pipe 2 and the first suction pipe 3 are both arranged in the housing 1. The carbon rod filter element is in the shape of a round tube, and the carbon rod filter element has a hollow channel. The carbon rod filter element can be sleeved on the outside of the first jet pipe 2 so that the carbon rod filter element and the first jet pipe 2 are coaxially arranged, and the first jet pipe 2 is located in the hollow channel of the carbon rod filter element. The inner wall of the carbon rod filter element and the outer wall of the first jet pipe 2 can be fitted or spaced.

[0031] See also Figure 2, a first jet hole 21 is provided on the side wall of the first jet pipe 2, and there are a plurality of first jet holes 21. The first jet holes 21 are distributed not only along the axial direction of the first jet pipe 2, but also along the circumferential direction of the first jet pipe 2, so as to cover the entire side wall of the first jet pipe 2. The first jet pipe 2 can obtain nitrogen from the gas tank 4, and then spray it to the entire inner wall of the carbon rod filter element through each first jet hole 21. Since the carbon rod filter element is a porous structure, the nitrogen can enter the side wall of the carbon rod filter element, and blow the carbon powder particles that are not effectively adhered to the side wall of the carbon rod filter element to the outside of the outer wall of the carbon rod filter element. Since the first suction pipe 3 extends along the radial direction of the first jet pipe 2 and is located outside the carbon rod filter element, and the air pump 5 provides suction power to the first suction pipe 3, the carbon powder particles ejected from the outer wall of the carbon rod filter element can enter the first suction pipe 3 and be sent to the air pump 5 for collection.

[0032] In this embodiment, the first air injection pipe 2 blows air inside the carbon rod filter element, and the first air suction pipe 3 sucks air outside the carbon rod filter element, thereby removing carbon powder particles that are not effectively adhered to the side wall of the carbon rod filter element, reducing the risk of carbon powder particles leaking during use of the carbon rod filter element.

[0033] In order to improve the collection effect of carbon powder particles, there are generally multiple first suction pipes 3. The housing 1 includes an inner cover 14 and an outer cover 15. The outer cover 15 is arranged on the outside of the inner cover 14, and the inner wall of the outer cover 15 and the outer wall of the inner cover 14 are arranged at intervals, so that the inner cover 14 and the outer cover 15 are arranged to form an exhaust chamber 11. The end of the first suction pipe 3 away from the first injection pipe 2 is arranged on the inner wall of the housing 1, so that the first suction pipe 3 is connected to the exhaust chamber 11, so that all the carbon powder particles sucked by the first suction pipe 3 will first enter the exhaust chamber 11. The side wall of the outer cover 15 is provided with a connection to the exhaust port 12, and the exhaust port 12 is connected to the air pump 5. The air pump 5 can provide suction to all the first suction pipes 3 at the same time through the exhaust port 12. In addition, the carbon powder particles in the exhaust chamber 11 can also go to the air pump 5 through the exhaust port 12.

[0034] The carbon rod filter element cleaning device of this embodiment further includes a substrate 8, which is installed at the opening of the housing 1, so that the substrate 8 and the inner cover 14 enclose a dust collecting chamber 13, and the substrate 8 also blocks the opening of the exhaust chamber 11. Therefore, the carbon powder particles ejected from the outer wall of the carbon rod filter element can only be sucked into the exhaust chamber 11 by the first suction pipe 3, and will not fall from the opening of the housing 1. The first air injection pipe 2 is perpendicular to the substrate 8.

[0035] In order to take out and put the carbon rod filter element in the dust collecting chamber 13, the housing 1 is detachably mounted on the base plate 8. It is particularly noteworthy that both the inner cover 14 and the outer cover 15 are detachably mounted on the base plate 8, that is, the inner cover 14 and the outer cover 15 are split structures, and the inner cover 14 and the outer cover 15 can be separated to facilitate cleaning of the carbon powder particles remaining in the exhaust chamber 11.

[0036] In order to enable the first air injection pipe 2 in the dust collecting chamber 13 to be connected with the gas tank 4 outside the dust collecting chamber 13, an air guide pipe 81 is passed through the base plate 8, one end of the air guide pipe 81 is located at the side edge of the base plate 8 to be connected to the gas tank 4, and the other end of the air guide pipe 81 is located on the upper surface of the base plate 8 to be connected with the lower end of the first air injection pipe 2.

[0037] If only the gas tank 4 works at the beginning and the air pump 5 does not work, the carbon powder particles ejected from the outer wall of the carbon rod filter element in the dust collecting chamber 13 will eventually be deposited on the substrate 8 due to gravity. Based on this phenomenon, in this embodiment, the air inlet end of at least one first air suction pipe 3 is in contact with the substrate 8, so that after the air pump 5 is turned on later, the carbon powder particles deposited on the substrate 8 can be sucked into the exhaust chamber 11 by the first air suction pipe 3 in contact with the substrate 8.

[0038] Some carbon powder particles are lighter in weight. After being ejected from the outer wall of the carbon rod filter element, these carbon powder particles will float in the dust collecting chamber 13 for a period of time. Under the action of the airflow in the dust collecting chamber 13, they may even float above the first injection pipe 2. In order to allow these carbon powder particles to enter the exhaust chamber 11 as quickly as possible, the air inlet end of at least one first intake pipe 3 is located at the end side of the first injection pipe 2 away from the substrate 8, that is, above the first injection pipe 2.

[0039] Embodiment 2:

[0040] See also Figure 3 The present embodiment provides a carbon rod filter element cleaning device, including a cover 1, a second air injection pipe 6, a second air suction pipe 7, an air tank and an air pump.

[0041] The gas tank is located outside the housing 1, the second jet pipe 6 is located inside the housing 1, the second jet pipe 6 is connected to the gas tank, the carbon rod filter element is arranged inside the housing 1, the second jet pipe 6 extends radially along the carbon rod filter element, the nitrogen in the gas tank can be ejected to the outer wall of the carbon rod filter element through the second jet pipe 6, based on the porous structure of the side wall of the carbon rod filter element, the nitrogen can enter the inside of the side wall of the carbon rod filter element, thereby blowing the carbon powder particles that are not fully adhered to the hollow channel of the carbon rod filter element. The two ends of the second suction pipe 7 are respectively connected to the hollow channel of the carbon rod filter element and the air pump, the air pump provides suction, and the carbon powder particles in the hollow channel are sucked out and collected through the second suction pipe 7.

[0042] In this embodiment, the second air injection pipe 6 blows air on the outside of the carbon rod filter element, and the second air suction pipe 7 sucks air at the end of the carbon rod filter element, thereby removing the carbon powder particles that are not effectively adhered to the side wall of the carbon rod filter element, reducing the risk of carbon powder particles leaking during use of the carbon rod filter element.

[0043] The carbon rod filter cleaning device also includes a base plate 8, which is installed at the opening of the housing 1 so that the base plate 8 and the housing 1 are surrounded to form a dust collecting chamber 13, the carbon rod filter is located in the dust collecting chamber 13 and is perpendicular to the base plate 8, and the lower end of the carbon rod filter is located on the upper surface of the base plate 8. The second suction pipe 7 is penetrated in the base plate 8, one end of the second suction pipe 7 is located on the upper surface of the base plate 8 to connect to the lower end of the hollow channel, and the other end of the second suction pipe 7 is located on the side edge of the base plate 8 to connect to the air pump, so that the carbon powder particles in the dust collecting chamber 13 can only leave through the second suction pipe 7 and be collected.

[0044] The base plate 8 and the cover shell 1 are detachable and compatible, so as to allow the carbon rod filter element in the dust collecting chamber 13 to be taken out and placed.

[0045] An air inlet cavity 16 is provided between the inner wall and the outer wall of the housing 1, an air inlet port 17 connected to the air inlet cavity 16 is provided on the outer wall of the housing 1, the air inlet cavity 16 is connected to the gas tank through the air inlet port 17, and the air inlet end of the second air jet pipe 6 is provided on the inner wall of the housing 1 to be connected to the air inlet cavity 16. Since the second air jet pipe 6 in this embodiment blows air into the dust collecting cavity 13, the carbon powder particles will not enter the air inlet cavity 16, and therefore there is no need to clean the carbon powder particles inside the air inlet cavity 16. Therefore, the housing 1 in this embodiment is an integrated structure.

[0046] Preferably, the carbon rod filter element cleaning device of this embodiment also includes a third air intake pipe 9, which is provided with a first air intake hole 91. The third air intake pipe 9 is located in the dust collecting chamber 13 and is passed through the hollow channel of the carbon rod filter element. The lower end of the third air intake pipe 9 is connected to the end of the second air intake pipe 7. The carbon powder particles can enter the third air intake pipe 9 through the first air intake hole 91 and then enter the second air intake pipe 7.

[0047] There are multiple first air intake holes 91 and they are distributed throughout the side wall of the third air intake pipe 9, so as to reduce the attenuation of the airflow suction in the hollow channel along the axial direction of the hollow channel, so that the upper end of the third air intake pipe 9 can also maintain a large suction force, so that the carbon powder particles in the entire hollow channel can be effectively sucked into the third air intake pipe 9.

[0048] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
