Description

Technical Field

[0001] This utility model relates to the field of pipeline descaling technology, and in particular to a descaling jet pipeline cleaning device. Background Technology

[0002] To ensure the quality and safety of fluid transported through pipelines, pipeline cleaning with pigs and regular maintenance are used to keep the pipelines in a near-new condition, guaranteeing efficient and safe operation. However, existing pipeline pigs are solid, propelled by fluid. When cleaning scale inside the pipeline, they are easily blocked by scale and stop, requiring the pipe to be opened and removed at the point of failure, which is time-consuming and labor-intensive. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a descaling jet pigging device.

[0004] The technical solution provided by this utility model is: a descaling jet cleaning device, including a reducer, which is a coaxial mechanical reduction mechanism. The reducer has a low-speed input shaft on the left and a high-speed output shaft on the right. A propeller A is fixedly connected to the low-speed input shaft. The high-speed output shaft is connected to the impeller through a flat key and a locking cap. The housing of the reducer is fixedly connected to the pump body on one side of the high-speed output shaft by bolts. The pump body is sleeved on the outside of the high-speed output shaft. A water inlet is opened on the pump body. A volute is sleeved on the outside of the impeller. A rear cover is connected to the left side of the volute by bolts. A bushing extends from the left side of the rear cover. The bushing is connected to the pump body through a bearing assembly, a spacer, a shaft retaining ring and a hole retaining ring. A propeller B is fixedly connected to the bushing. The outer circular surface of the volute has nozzles evenly distributed around its circumference.

[0005] The reducer housing is provided with circumferentially distributed support components. The support components are arranged radially along the reducer. The support components include rollers and roller brackets. The rollers abut against the inner wall of the pipe. The rollers are rotatably connected to the roller brackets. The inner side of the roller brackets is provided with positioning pins B. A compression spring A is sleeved on the positioning pin B. The other side of the compression spring A is sleeved on the positioning pin C. The inner side of the positioning pin C is provided with a fixing pin. The fixing pin is fixedly connected to the reducer housing.

[0006] The wheel bracket consists of two side plates and a top plate. The inner side of the two side plates is connected to the gate plate via guide rails. The gate plate is located on the upper side of the roller. The lower part of the top plate is fixedly connected to the positioning column A. A compression spring B is fitted on the positioning column A. The lower end of the compression spring B is on the base of the gate plate.

[0007] The rollers are made of rubber.

[0008] The outer circle of the roller is an arc-shaped annular surface, which has the same radius as the inner wall of the pipe. The lower end face of the gate is an arc-shaped surface, which fits into the outer circle of the roller.

[0009] The beneficial effects of this utility model are as follows: A support assembly is installed on the outside of the reducer. A gate is provided on the roller of the support assembly. Under the action of the compression spring B, the gate can limit the rolling of the roller. The support assembly limits the rolling of the reducer in the pipeline, so that the reducer moves slowly in the pipeline and rotates slowly or not at all. There is a speed difference between the propeller A and the fluid, so the kinetic energy of the fluid is used for descaling. The descaling jet cleaner is placed in the pipeline, and high-speed fluid is introduced into the pipeline. The high-speed fluid impacts the propeller A, and the propeller A and the low-speed input shaft rotate. The high-speed output shaft of the reducer rotates at high speed, and the high-speed output shaft drives the impeller to rotate. The liquid is sucked into the impeller from the inlet and pressurized. The pressurized fluid is sprayed out from the nozzle to descal. Since the volute is connected to the propeller B, the volute rotates at a certain speed, and the nozzle can descale in all directions in the pipeline. Attached Figure Description

Detailed Implementation

[0015] like Figures 1-4As shown, a descaling jet cleaning device includes a reducer 1, which is a coaxial mechanical reduction mechanism. The reducer 1 has a low-speed input shaft 4 on the left and a high-speed output shaft 5 on the right. A propeller A2 is fixedly connected to the low-speed input shaft 4. The high-speed output shaft 5 is connected to the impeller 6 through a flat key and a locking cap. The housing of the reducer 1 is fixedly connected to the pump body 3 on one side of the high-speed output shaft 5 by bolts. The pump body 3 is sleeved on the outside of the high-speed output shaft 5. The pump body 3 has an inlet 11. A volute 7 is sleeved on the outside of the impeller 6. The left side of the volute 7 is connected to a rear cover 8 by bolts. A bushing 81 extends from the left side of the rear cover 8. The bushing 81 is connected to the pump body 3 through a bearing assembly, a spacer 12, a shaft retaining ring, and a hole retaining ring. The bushing 81, the rear cover 8, and the volute 7 can rotate around the pump body 3. A propeller B10 is fixedly connected to the bushing 81. The outer surface of the volute 7 has nozzles 9 evenly distributed around its circumference.

[0016] The reducer 1 housing is provided with circumferentially distributed support components. The support components are arranged radially along the reducer 1. The support components include rollers 14 and roller brackets 13. The rollers 14 abut against the inner wall of the pipe. The rollers 14 are rotatably connected to the roller brackets 13. The inner side of the roller brackets 13 is provided with a positioning post B21. A compression spring A16 is sleeved on the positioning post B21. The other side of the compression spring A16 is sleeved on the positioning post C22. The inner side of the positioning post C22 is provided with a fixing post 15. The fixing post 15 is fixedly connected to the reducer 1 housing.

[0017] The wheel bracket 13 consists of two side plates 131 and a top plate 132. The inner side of the two side plates 131 is connected to the gate plate 17 via a guide rail 18. The gate plate 17 is lower than the roller 14. The lower part of the top plate 132 is fixedly connected to the positioning column A20. A compression spring B19 is sleeved on the positioning column A20. The lower end of the compression spring B19 is on the gate plate 17.

[0018] A support assembly is installed on the outside of the reducer 1. A gate 17 is provided on the roller 14 of the support assembly. The gate 17 can limit the rolling of the roller 14 under the action of the compression spring B19, thus limiting the rolling of the reducer 1 in the pipeline. This allows the reducer 1 to move slowly in the pipeline. The reducer 1 rotates slowly or does not rotate at the same time. There is a speed difference between the propeller A2 and the fluid, so the kinetic energy of the fluid is used for descaling. The descaling jet cleaner is placed in the pipeline, and high-speed fluid is introduced into the pipeline. The high-speed fluid impacts the propeller A2, causing the propeller A2 and the low-speed input shaft 4 to rotate. The high-speed output shaft 5 of the reducer 1 rotates at high speed, and the high-speed output shaft 5 drives the impeller 6 to rotate. Liquid is drawn in from the inlet 11 and pressurized. The pressurized fluid is sprayed out from the nozzle 9 for descaling. Since the volute 7 is connected to the propeller B10, the volute 7 rotates at a certain speed, and the nozzle 9 can perform descaling in all directions in the pipeline.

[0019] Roller 14 is made of rubber to increase friction.

[0020] The outer circle of roller 14 is an arc-shaped annular surface, which has the same radius as the inner wall of the pipe. The lower end face of gate 17 is an arc-shaped surface, which fits into the outer circle of roller 14 to improve the braking effect.
