In the present application, the maximum outer edge of the rotary cutting surface formed by the blade 42 after rotation may be the same as the outer diameter of the fixed cylinder 3, so as to prevent the blade 42 from touching the inner wall of the pipeline to be cleaned during rotation. The blades 42 are provided with a plurality of groups, and form a plurality of rotary-cut surfaces, that is, a plurality of groups of rotary-cut surfaces are provided, and each rotary-cut surface is provided with a plurality of groups of blades 42, wherein the diameter of the rotary-cut surface gradually decreases along the advancing direction, that is, the length of the blade 42 on each rotary-cut surface gradually decreases along the advancing direction; the design is convenient for the whole pipe cleaning device to clean the deposition blocks layer by layer, and the condition that the deposition blocks are clamped due to overlarge feeding of the blades 42 during rotary cutting is avoided.
It should be noted that, in the present application, some sliding wheel structures may also be designed on the outer wall of the fixed cylinder 3 along the circumferential direction, and the sliding wheels are used to keep the whole fixed cylinder 3 in a coaxial position relative to the pipeline to be cleaned. Certainly in practice, the outer diameter of the fixed cylinder 3 can be made to be the same as the inner diameter of the pipeline to be cleaned, so that the pipe cleaning device can be directly plugged into the pipeline to be cleaned for cleaning.

Referring to fig. 1 to 5, the fixed cylinder 3 comprises an inner cylinder 34 and an outer cylinder 35 which are coaxially arranged, one ends of the inner cylinder 34 and the outer cylinder 35 far away from the suction pipe 1 are connected through a plugging ring 36, and the interlayer 31 is formed; the suction pipe 1 is sleeved on the outer wall of one end of the outer cylinder 35 far away from the plugging ring 36, the suction channel 33 is arranged on the outer cylinder 35, and the air passing channel 32 is arranged on the inner cylinder 34 and is arranged on the front side of the suction channel 33; the drum 41 is rotatably inserted into the inner cylinder 34. In actual use, a bearing structure can be mounted between the drum 41 and the inner drum 34 for better rotation of the drum relative to the inner drum 34. In the present application, the inner cylinder 34 and the outer cylinder 35 can be supported and connected through some rod-shaped structures, and the strength of the whole fixed cylinder 3 is maintained. In order to reduce the deposition clogging of deposits in the interlayer 31, the thickness of the interlayer 31 may be increased appropriately, with a ratio of the thickness to the diameter of the gas supply pipe 2 of 2: 1 or more. The suction channel 33 may in this case be a slotted structure, the main purpose of which is to suck the detached deposits by means of a high-speed air flow passing through the intermediate layer 31.
With further reference to fig. 3 and 4, in an embodiment of the present application, the suction channel 33 is annularly disposed on a side wall of the outer cylinder 35, the outer cylinder 35 is connected to two side portions of the suction channel 33 through a connection column 37, a bevel 331 is obliquely disposed on one side of the suction channel 33 in an advancing direction of the outer cylinder 35, and the bevel 331 is smoothly transited to an outer wall of the outer cylinder 35. The groove 331 is configured to enable the entire suction channel 33 to be flared, thereby not only collecting deposits, but also preventing the suction channel 33 from being opened too much and reducing the suction force caused by the high-speed airflow therein. In addition, the side of the suction channel 33 behind the outer cylinder 35 gradually bulges outward and forms a scraper ring 332, and the scraper ring 332 can be deformed. It should be noted that in the present application, the scraper ring 332 is configured similar to a cup structure used in conventional pigging. The scraping ring 332 is designed mainly for blocking the pipeline to be cleaned, so that the phenomenon that the cleaned and fallen sediments are arranged in sequence when the whole pipe cleaning device moves forward is avoided, and the scraping ring 332 is used for positioning the position of the whole pipe cleaning device in the pipeline to be cleaned, so that the head rotating assembly 4 is convenient; more importantly, the scraping ring 332 plays a role in isolating the pipeline to be cleaned, so that the detached sediment is pushed by the scraping ring 332 and collected into a pile by the scraping ring 332, thereby facilitating the suction of the suction channel 33.
Referring to fig. 3 and 5, in order to facilitate installation of the drum 41, the inner cylinder 34 is provided with an annular ring platform 38 inward, and one end of the air passing channel 32 communicating with the air passing hole 43 is provided on a side surface of the ring platform 38 directed to one side of the inner cylinder 34 in the axial direction; the rotating cylinder 41 is movably inserted on the ring platform 38, and the rotating cylinder 41 is positioned on two sides of the ring platform 38 and is installed on the inner cylinder 34 through the rotating bearing 5; the end of the drum 41 remote from the blade 42 is provided with a lock nut 45, and the lock nut 45 locks the inner ring of the rotary bearing 5 on the corresponding side. In order to increase the practical use effect in the application, the annular table 38 and the rotating cylinder 41 are in clearance fit, so that the installation is convenient, and meanwhile, the mutual abrasion of the annular table 38 and the rotating cylinder 41 in the use process is reduced. If clearance fit is adopted, in order to ensure the tightness between the overflowing hole 43 and the overflowing channel 32, the middle part of the annular platform 38 is inwards sunken to be provided with an annular groove 39 in one embodiment of the application, the port of the overflowing channel 32 is arranged in the annular groove 39, and the annular groove 39 is opposite to the port of the overflowing hole 43. The ring platform 38 is provided with sealing elements 3a on both sides of the ring groove 39, and the sealing elements 3a abut against the outer wall of the rotating drum 41. The sealing element 3a can effectively ensure that the connection between the overflowing hole 43 on the outer wall of the rotating drum 41 and the air passing channel 32 is stable, and meanwhile, the annular groove 39 is designed so that high-speed airflow sprayed out of the overflowing hole 43 is always received by the annular groove 39 when the rotating drum 41 rotates, and the airflow is introduced into the air passing channel 32 and finally enters the interlayer 31. In addition, in order to increase the flow capacity of the air flow, the air passage 32 is a slotted hole structure and is formed on the bottom or the side wall of the ring groove 39. The actual use of the flow holes 43 is also designed to reduce the actual flow resistance of the fluid.
Referring to fig. 3 and 5, the drum 41 may have a variety of configurations in the present application, one specific example of which is as follows. The rotating cylinder 41 comprises a rotating part 411 and an end head part 412, the rotating part 411 is rotatably arranged in the fixed cylinder 3, one end of the end head part 412 facing outwards is closed, and the other end of the end head part is connected with the rotating part 411; one end of the rotating part 411, which is far away from the end head part 412, is rotatably connected with the air supply pipe 2, the overflowing hole 43 is arranged on the rotating part 411, one side of the end head part 412, which is close to the rotating part 411, gradually extends outwards in an inclined manner to form a conical cylinder 413, and the conical cylinder 413 is movably sleeved outside the fixed cylinder 3; the blades 42 are uniformly arranged on the outer wall of the cone 413, but the blades 42 may also be arranged on the outer wall of the head part 412. The structure design of the cone 413 is similar to a protective cone sleeve, so that fallen or cleaned sediments cannot enter between the annular table 38 and the rotary drum 41 when the cleaning pipe of the whole cleaning device advances, and the influence of the sediments on the rotation between the annular table 38 and the rotary drum 41 is avoided. In addition, the structure of the cone 413 can better protect the fixed cylinder 3, and the structure of matching the fixed cylinder 3 with the rotary head component 4 forms a clip-shaped structure, so that external sediments are difficult to enter between the fixed cylinder 3 and the rotary head component 4. In actual use, a sealing ring structure can be arranged between the outer wall of the outer cylinder 35 and the inner wall of the conical cylinder 413, so that the outer cylinder 35 and the conical cylinder 413 are sealed in a rotating manner, and the protection performance is improved. In the present invention, the diameter of the head part 412 is gradually increased rearward at the foremost end in the forward direction, and the diameter of the tapered tube 413 region is larger than the diameter of the outer tube 35, but the diameters of the tapered tube 413 at the front and rear ends are uniform. Specifically, the end portion 412 has a conical head structure, and the area where the conical tube 413 is matched with the outer tube 35 has a cylindrical structure.

The structural design of the closing mechanism 6 ensures that the whole pipe cleaning device is a simple rotary head structure, and can drive the blade 42 to rotate and cut sediments in the pipeline to be cleaned by utilizing the rotation of the whole pipe cleaning device. In actual use, since the deposit is not continuously present, in order to enhance the cutting strength of the blade 42, the closing mechanism 6 may be opened at a distance to suck the fallen deposit.
