Description

Technical Field

[0001] The utility model relates to the field of plugging removal equipment, in particular to a plugging removal equipment for boiler pipelines. Background Technique

[0002] The original meaning of "pot" refers to a water container heated on fire, and "furnace" refers to a place for burning fuel. A boiler includes two major parts: a pot and a furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's livelihood, or can be converted into mechanical energy through a steam power device, or further converted into electrical energy through a generator. A boiler that provides hot water is called a hot water boiler, which is mainly used for life and has a small amount of application in industrial production. A boiler that generates steam is called a steam boiler, often simply referred to as a boiler, and is mostly used in thermal power plants, ships, locomotives, and industrial and mining enterprises.

[0003] Chinese Patent No. CN202322845555.3 discloses a plugging removal equipment for boiler pipelines, which includes two bottom plates. Two support frames are welded and installed on the tops of the two bottom plates. A boiler body is fixedly installed inside the two support frames. Four boiler pipeline bodies are fixedly installed on one side of the outer surface of the boiler body. A plugging removal structure is fixedly installed on one side of the outer surface of the four boiler pipeline bodies; the plugging removal structure includes an installation box. A communication groove is opened inside the installation box, and the communication groove communicates with the boiler pipeline body. An installation plate is fixedly installed inside the installation box, and a steel ball rotating shaft is rotatably installed inside the installation plate.

[0004] As can be seen from the above, when the boiler pipeline body is blocked, driven by a hydraulic cylinder, the telescopic rod drives the cross bar to move. Due to the thread grooves provided on the surface of the threaded groove rod and the stoppers inside the steel ball rotating shaft, when the cross bar drives the threaded groove rod to move, the threaded groove rod passes through the steel ball rotating shaft and rotates. Thus, the descaling sleeve can scrape off the scale and foreign matters attached to the inner wall of the boiler pipeline body, and through the continuous advancement of the threaded groove rod, push them out. Thus, the purpose of quickly cleaning the scale and preventing blockage is achieved, and the working efficiency of the boiler body is improved. However, there are still the following deficiencies in this case: When performing the plugging removal operation on the boiler pipeline, the prior art usually flushes the inner cavity of the pipeline with water pressure to make the attachments on the pipeline wall fall off. When there are stubborn attachments on the pipeline, when the water pressure does not meet the requirements, the attachments cannot be removed.

[0005] Therefore, a plugging removal equipment for boiler pipelines is proposed to solve the above problems. Content of the Utility Model

[0006] In order to make up for the deficiencies of the prior art and solve the problem that the attachments cannot be removed when the water pressure does not meet the requirements, the utility model proposes a plugging removal equipment for boiler pipelines.

[0007] The technical solution adopted by the present utility model to solve its technical problems is as follows: A boiler pipeline blockage clearing device described in the present utility model includes a main body and a movable blockage clearing device; a fixed frame is installed on the movable blockage clearing device, several limiting wheels are installed at the bottom of the fixed frame, a water storage tank is fixedly installed at the top of the fixed frame, a pump is fixedly installed at the top of the water storage tank, a telescopic corrugated pipe is fixedly installed on one side of the pump, the other end of the telescopic corrugated pipe is fixedly installed with a connection chamber, and a flushing nozzle is fixedly installed on the other side of the connection chamber.

[0008] Preferably, a base is installed on the main body, a boiler is fixedly installed on the top of the base, and a pipeline is fixedly installed on one side of the boiler.

[0009] Preferably, a first hydraulic cylinder is fixedly installed at the top of the water storage tank, a first piston rod is movably installed at the output end of the first hydraulic cylinder, and a connection block is fixedly installed at one end of the first piston rod.

[0010] Preferably, a second hydraulic cylinder is fixedly installed through and on one side of the connection block, a second piston rod is movably installed at the output end of the second hydraulic cylinder, and a connection chamber is movably installed at one end of the second piston rod.

[0011] Preferably, a seal is fixedly installed on one side of the flushing nozzle, a torque motor is fixedly installed in the inner cavity of the seal, a turntable is fixedly installed at the output end of the torque motor, and several scrapers are movably installed around the turntable.

[0012] Preferably, three connecting seats are fixedly installed around the seal, movable blocks are hinged on both sides of the connecting seats, a spring is fixedly installed between the two movable blocks, and rollers are respectively movably installed on one side of the two movable blocks.

[0013] The beneficial effects of the present utility model are as follows:

[0014] Through the structural design of the movable blockage clearing device of the present utility model, the turntable is driven to rotate by the torque motor, so that the scrapers around the turntable scrape the inside of the pipeline, and the stubborn attachments inside the pipeline are processed. Cooperating with the first hydraulic cylinder, the first piston rod extends and retracts to one side, so that one end of the first piston rod drives the connection block to displace to one side. At this time, the seal and the scraper move accordingly in linkage. The pump delivers water through the telescopic corrugated pipe to the connection chamber, and it is output outward by the flushing nozzle to wash the inner cavity of the pipeline, realizing the function of movable clearing, solving the problem that the attachments cannot be cleared when the water pressure does not meet the requirements, and improving the limitations in use.

[0024] During operation, through the installation of the limiting wheels 22, the whole device can be moved by the limiting wheels 22 during use. The pump pumps the water stored in the water storage tank 23, and conveys the water through the telescopic corrugated pipe 26 to the connection chamber 32 and the flushing nozzle 33, which is beneficial to the flushing operation inside the pipeline 13.

[0025] Furthermore, a base 11 is installed on the main body 1, a boiler 12 is fixedly installed on the top of the base 11, and a pipeline 13 is fixedly installed on one side of the boiler 12;

[0026] During operation, the base 11 supports the boiler 12, which is beneficial to ensuring the stability during the whole operation.

[0027] Furthermore, a first hydraulic cylinder 25 is fixedly installed on the top of the water storage tank 23, a first piston rod 27 is movably installed at the output end of the first hydraulic cylinder 25, and a connecting block 28 is fixedly installed at one end of the first piston rod 27;

[0028] During operation, the first hydraulic cylinder 25 converts hydraulic energy into mechanical energy to drive the first piston rod 27 to perform corresponding movements, which is beneficial to realizing the relative displacement movement of the connecting block 28 during operation.

[0029] Furthermore, a second hydraulic cylinder 29 is fixedly installed through and on one side of the connecting block 28, a second piston rod 31 is movably installed at the output end of the second hydraulic cylinder 29, and a connection chamber 32 is movably installed at one end of the second piston rod 31;

[0030] During operation, when the first piston rod 27 moves to a certain position, the cooperation of the second hydraulic cylinder 29 and the second piston rod 31 is beneficial to extending the movement distance of the connection chamber 32.

[0031] Furthermore, a seal 34 is fixedly installed on one side of the flushing nozzle 33, a torque motor 39 is fixedly installed in the inner cavity of the seal 34, a turntable 41 is fixedly installed at the output end of the torque motor 39, and several scrapers 42 are movably installed around the turntable 41;

[0032] During operation, the flushing nozzle 33 drives the seal 34 to perform synchronous movements. During the movement, the driving torque motor 39 makes the turntable 41 perform rotational movements, which is beneficial to scraping the inner cavity of the pipeline 13 through the scrapers 42.

[0033] Further, three connecting seats 35 are fixedly installed around the seal 34. The two sides of the connecting seat 35 are hinged with movable blocks 36.

[0034] During operation, when the seal 34 moves in the inner cavity of the pipeline 13, to ensure stability during movement, the installation of the movable block 36 is beneficial to the overall stability during movement. At the same time, in cooperation with the hinged movable block 36 and the spring 37, it will stretch correspondingly along with the inside of the pipeline 13.

[0035] Working principle: By driving the first hydraulic cylinder 25, the first piston rod 27 extends and retracts to one side, causing one end of the first piston rod 27 to drive the connecting block 28 to displace to one side. At this time, the seal 34 moves correspondingly along with the linkage. The torque motor 39 drives the turntable 41 to rotate, so that the scraping knives 42 around the turntable 41 scrape the inside of the pipeline 13 to handle the stubborn attachments inside the pipeline 13. At the same time, the pump 24 is driven to pump the water in the water storage tank 23, so that the water is transported to the connection bin 32 through the telescopic corrugated pipe 26 and is pressurized by the flushing nozzle 33 to flush the inner cavity of the pipeline 13. When the moving distance of the first piston rod 27 reaches a certain distance, at this time, the second hydraulic cylinder 29 is driven to make the second piston rod 31 perform corresponding telescopic movement, and one end of the second piston rod 31 drives the connection bin 32 to continuously push the turntable 41 forward.
