Technical Field

[0001] The present invention relates to the technical field of descaling devices, in particular to an in-pipe descaling device with strong adaptability to pipeline shapes. Background Art

[0002] Long-term use can lead to scale buildup on the surface of pipes due to impure fluids within them. Failure to clean this layer of scale can impair heat transfer efficiency and flow characteristics, thereby impacting production efficiency. Current cleaning devices primarily utilize scraping to remove scale from circular pipe surfaces, but these methods are ineffective against curved pipes, reducers, and internally ribbed pipes. Furthermore, removed scale can accumulate near the brush, compromising subsequent descaling efforts. Therefore, a descaling device that can adapt to various pipe shapes and remove scale near the brush is essential. Summary of the Invention

[0033] like Figure 1-6 As shown, an in-pipe descaling device with strong adaptability to the shape of the pipeline includes a descaling component, and both ends of the descaling component are provided with support components for supporting the descaling component;

[0034] The descaling assembly includes an inner tube body 2-6, an outer shell 2-1, a nozzle 3-2 and a brush rod 3-3. The inner tube body 2-6 is rotatably mounted in the outer shell 2-1 through a bearing. The nozzle 3-2 is fixedly mounted on the nozzle seat 3-1. The nozzle seat 3-1 is hinged to the outer shell 2-1 through a pin shaft 2-2. The brush rod 3-3 is hinged to the outer shell 2-1 through a pin shaft 2-2. A brush 3-4 is provided on the brush rod 3-3. The brush 3-4 is located at the end of the brush rod 3-3 away from the outer shell 2-1. The brush 3-4 is used to remove dirt on the inner wall of the pipe. A control mechanism is provided between the outer shell 2-1 and the brush rod 3-3. The control mechanism is used to control the brush 3-4 to always fit the inner wall of the pipe. A linkage mechanism is provided between the nozzle 3-2 and the brush rod 3-3. The linkage mechanism is used to control the nozzle 3-2 to always spray toward the brush 3-4. The inner tube body 2-6 includes a nozzle and a brush rod. The invention comprises a front tube body, a rear tube body and a spacer 2-7, one end of the rear tube body is inserted into the front tube body, a first flange is provided at one end of the front tube body close to the rear tube body, a second flange is provided at one end of the rear tube body close to the front tube body, the first flange and the second flange are arranged opposite to each other, a first annular groove is provided at one end of the first flange away from the second flange, a second annular groove is provided at one end of the second flange away from the first flange, a first protrusion and a second protrusion are provided on the spacer 2-7, the first protrusion matches the first annular groove, and the second protrusion matches the second annular groove, so as to realize a rotationally sealed connection between the spacer 2-7 and the front tube body and the rear tube body, a through hole connected to the spacer 2-7 is provided on the inner tube body 2-6, and one end of the nozzle 3-2 is connected to the spacer 2-7 through the branch pipe 2-8, so as to realize a rotationally sealed connection between the inner tube body 2-6 and the nozzle 3-2.

[0035] The linkage mechanism includes a connecting rod 3-6, one end of which is fixedly connected to the nozzle 3-2, a sliding groove matching the connecting rod 3-6 is provided on the brush rod 3-3, and the other end of the connecting rod 3-6 is slidably arranged in the sliding groove.

[0036] The control mechanism includes a tension spring 3-5, one end of the tension spring 3-5 is arranged on the outer shell 2-1, and the other end of the tension spring 3-5 is arranged on the brush rod 3-3.

[0037] The descaling assembly also includes an eccentric impeller 2-9 that is rotatably disposed within the inner tube 2-6. The eccentric impeller 2-9 is eccentrically fixed to the inner tube 2-6 via an impeller bracket 2-10. The water flow drives the eccentric impeller 2-9 to rotate rapidly, causing the outer shell 2-1 and the brush rod 3-3 on the outer shell 2-1 to vibrate, thereby further removing dirt that is difficult to remove by scratching.

[0038] In order to increase the cleaning range of the descaling device, several descaling assemblies are connected in series between the support assemblies at both ends. The inner tube bodies 2-6 between two adjacent descaling assemblies are interconnected through a flexible hose, and the two adjacent descaling assemblies are connected through a bellows 2-4. The hose is arranged in the bellows 2-4, and the spraying directions of the nozzles 3-2 between the two adjacent descaling assemblies are opposite.

[0039] The support assembly includes a base 1-1, a driven wheel 1-4 that can be rested on the inner wall of the pipe, and a support spring 1-2. One end of the support spring 1-2 is set on the base 1-1, and the other end of the support spring 1-2 is set on the driven wheel 1-4. The driven wheel 1-4 is provided with a front brush seat 1-3 to prevent dirt from hindering the forward movement of the driven wheel 1-4.

[0040] Since one end of the inner tube 2-6 on the descaling assembly is connected to the base 1-1, in order to protect the hose and at the same time play an aesthetic role, a bellows 2-4 is used to connect the base 1-1 and the outer shell 2-1 of the descaling assembly.

[0041] To enhance the descaling effect, a venturi tube 3-7 is provided within the nozzle 3-2, which is also equipped with a swirl blade 3-8 located between the venturi tube 3-7 and the nozzle opening of the nozzle 3-2. The nozzle 3-2 sprays water mixed with air bubbles, which burst when the water hits the wall, softening and dislodging the dirt under the impact of the bursting bubbles.

[0042] When the above-mentioned in-pipe descaling device with strong adaptability to the shape of the pipe is in use, the entire descaling device is placed in the pipe that needs to be descaled. First, the driven wheels 1-4 on the base 1-1 of the front and rear end support components are made to contact the inner wall of the pipe under the action of the support spring 1-2. At the same time, the brush 3-4 of the brush rod 3-3 of the descaling component also contacts the inner wall of the pipe. Then one end of the hose is connected to the external water source to realize the spraying of the nozzle 3-2 to the brush 3-4. The descaling device is driven to move forward in the pipe by one end. Since the nozzles 3-2 of the outer shells 2-1 on the two adjacent descaling components are in opposite directions, the outer shells 2-1 are driven to rotate on the inner pipe body 2-6. The outer shells 2-1 of the two adjacent descaling components rotate in opposite directions, which increases the descaling range and improves the descaling efficiency.

[0043] When encountering a pipe of variable diameter or a pipe of different shape, under the action of the support spring 1-2, the driven wheel 1-4 is pressed against the inner wall of the pipe. At the same time, under the action of the tension spring 3-5, the brush rod 3-3 swings on the outer shell 2-1, and the brush 3-4 at one end of the brush always fits against the inner wall of the pipe. At the same time, the slide groove on the brush rod 3-3 drives the connecting rod 3-6 to rise or fall, which drives the nozzle 3-2 to swing upward or downward and always spray towards the brush 3-4, thereby improving the applicability of the descaling device.

[0044] The above description of the preferred embodiments of the present invention is intended to serve as a guide. Based on the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
