DETAILED DESCRIPTION

[0037] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the utility model.

In some figures, components with the same structure or function are only schematically illustrated, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0038] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0039] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0040] Reference Figure 1~Figure 5 , which is the first embodiment of the utility model, proposes a direct-flow T-type filter, including: a main body 1, having a cavity 1-1; an air inlet pipe 2, arranged on the main body 1 and connected to the cavity 1-1; a filter pipe 3, arranged in the cavity 1-1 and connected to the cavity 1-1; an air outlet pipe 4, arranged on the main body 1 and connected to the filter pipe 3; a rotating wiper 5, rotatably arranged in the cavity 1-1, for wiping the filter pipe 3.

[0041] In this embodiment, in order to solve the problem that the T-type gas filter in the related art cannot fully clean the filter element after being used for a period of time, this solution designs a rotating wiper 5 to clean the filter element. The cleaning process in this solution is completed in a shutdown state. When no gas passes through the main body 1, the rotating wiper 5 is rotated to make the rotating wiper 5 contact the outer side of the filter pipe. During the rotation process after contact, impurities attached to the outer side of the filter pipe 3 can be cleaned off, which improves the filtering efficiency of the gas on the one hand, and prolongs the service life of the filter pipe 3 on the other hand.

[0042] Furthermore, the rotating wiping member 5 includes: a plurality of mounting ring plates 5-1, which are rotatably arranged between the main body 1 and the filter pipe 3 and are arranged at intervals along the axial direction of the filter pipe 3; a connecting column 5-2, which is arranged on the plurality of mounting ring plates 5-1 and is used to connect the plurality of mounting ring plates 5-1; a wiping unit 5-3, which is arranged on the plurality of mounting ring plates 5-1, the wiping unit 5-3 is in contact with the filter pipe 3, and the mounting ring plate 5-1 rotates to drive the wiping unit 5-3 to wipe along the outer wall of the filter pipe 3.

[0043] In this embodiment, in order to specifically achieve the effect of wiping the filter pipe 3 after the rotating wiping member 5 rotates, the wiping unit 5-3 is designed to be in the shape of a long strip. The length of the wiping unit 5-3 is greater than the length of the filter pipe 3 to ensure that the wiping unit 5-3 can fully wipe the filter pipe 3. Since the filter pipe 3 is located in the middle of the cavity 1-1, in order to wipe the outside of the filter pipe 3, the present invention designs a mounting ring plate 5-1. The hollow structure in the middle of the mounting ring plate 5-1 is to avoid the filter pipe 3. Since both ends of the long wiping unit 5-3 need to be fixed, at least two mounting ring plates 5-1 are required to fix the top and bottom ends of the wiping unit 5-3. In order to save costs, the present invention uses several mounting ring plates 5-1 for connecting the connecting column 5-2. After the connection, only one drive is needed to drive all the mounting ring plates 5-1 to rotate at the same time. After the mounting ring plate 5-1 rotates, it drives the wiping unit 5-3 to rotate on the outside of the filter pipe 3 to wipe the outside of the filter pipe 3.

[0044] Furthermore, the mounting ring plate 5-1 has an arc groove 5-6, and the wiping unit 5-3 is slidably set in the arc groove 5-6. It also includes: a limit plate 5-5, which is set in the cavity 1-1 and has a slide groove 5-7. The wiping unit 5-3 is slidably set in the slide groove 5-7. After the mounting ring plate 5-1 and the limit plate 5-5 rotate relative to each other, the wiping unit 5-3 approaches or moves away from the filter pipe 3 through the arc groove 5-6 and the slide groove 5-7.

[0045] In this embodiment, in order to prevent the wiping unit 5-3 from affecting the gas transmission efficiency when it contacts the filter pipe 3, the wiping unit 5-3 is designed in this solution so that when the gas is filtered in the filter pipe 3, the wiping unit 5-3 is away from the outside of the wiping unit 5-3, and when the gas does not pass through the filter pipe 3, the wiping unit 5-3 can wipe the outside of the filter pipe 3 by approaching it. In this solution, an arc groove 5-6 is designed on the mounting ring plate 5-1, and a slide groove 5-7 is designed on the limit plate 5-5. The wiping unit 5-3 passes through the arc groove 5-6 and the slide groove 5-7 at the same time. When the mounting ring plate 5-1 rotates, due to the limitation of the slide groove 5-7, the wiping unit 5-3 can only approach or move away from the outside of the filter pipe 3. When it approaches, it wipes, and when it moves away, it prevents affecting the filtering rate. In this solution, a position detection component is designed at the position where the slide groove 5-7 is closest to the filter pipe 3. When the detection component detects that the wiping unit 5-3 is close to the filter pipe 3, a signal is sent to the control component, and the control component controls the limit plate 5-5 and the mounting ring plate 5-1 to rotate synchronously.

[0046] Furthermore, the outer ring of the mounting ring plate 5-1 at the top has a plurality of first teeth 5-8, and also includes: a driving gear 6, which is arranged on the main body 1, and the driving gear 6 is used to drive the first teeth 5-8 to rotate. The inner ring of the mounting ring plate 5-1 at the top has a plurality of second teeth, and also includes: a first gear 7, which is rotatably arranged on the main body 1 and located on the inner side of the mounting ring plate 5-1, and the second teeth are meshed with the first gear 7; a second gear 8, which is arranged at the top of the wiping unit 5-3, and when the wiping unit 5-3 abuts against the filter pipe 3, the first gear 7 is meshed with the second gear 8.

[0047] In this embodiment, in order to realize automatic control of the wiping work, this scheme drives the mounting ring plate 5-1 to rotate by utilizing the active gear 6. After the mounting ring plate 5-1 rotates, it drives the first gear 7 to rotate. When the mounting ring plate 5-1 rotates normally when performing the wiping command, the wiping unit 5-3 approaches the filter pipe 3. When the wiping unit 5-3 contacts the wiping pipe, the second gear 8 and the first gear 7 engage. Since the second tooth and the first gear 7 are always in a meshing state, under the wiping command, when the mounting ring plate 5-1 rotates, when the wiping unit 5-3 approaches the filter pipe 3 for wiping, the wiping unit 5-3 starts to rotate. The two operating states of the wiping unit 5-3 speed up the cleaning efficiency.

[0048] Furthermore, it also includes: a valve 9, which is rotatably arranged in the air inlet pipe 2 and the air outlet pipe 4. The main body 1 also has a sewage outlet 1-2. It also includes: an air inlet pipe 10, which is arranged on the main body 1 and is connected to the filter pipe 3.

[0049] In this embodiment, in order to ensure that the cleaned impurities can be removed from the cavity 1-1, the present scheme first closes the valve 9 to make the cavity 1-1 in a closed state, opens the air inlet pipe 10, and allows the gas to blow back from the inside of the filter pipe 3 to the outside, and cleans the places that the wiping unit 5-3 cannot wipe, and opens the sewage outlet 1-2, which is located at the lower end of the cavity 1-1. The gas in the air inlet pipe 10 is blown downward to discharge the impurities from the sewage outlet 1-2.

[0050] Furthermore, the mounting ring plate 5-1 and the limiting plate 5-5 both have a plurality of ventilation holes.

[0051] In this embodiment, in order to prevent the installation ring plate 5-1 and the limit plate 5-5 from affecting the filtration rate, this solution designs ventilation holes on the installation ring plate 5-1 and the limit plate 5-5, and the ventilation holes can pass sufficient gas.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
