Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a rapid cleaning device for boilers in thermal power plants. Background Technology

[0002] A thermal power plant boiler is an energy conversion device. The energy input to the boiler includes the chemical energy of the fuel and electrical energy. The boiler outputs steam with a certain amount of thermal energy, which is converted into mechanical energy through a steam power device, or the mechanical energy is converted into electrical energy through a generator. After long-term use, a large amount of dust from fuel combustion will accumulate on the inner wall of the boiler, forming a dust layer of a certain thickness. This will reduce the fuel utilization rate and also bring safety hazards, making it necessary to use a cleaning device to clean the inner wall of the boiler.

[0003] In the prior art, such as the rapid cleaning device for boilers in thermal power plants disclosed in publication number CN217057567U, a method is proposed that can automatically add water to the boiler and use a brush to clean the inner wall of the boiler. However, the wastewater after cleaning cannot be discharged from the boiler, and workers still need to pump the water after cleaning. At this time, impurities may have already precipitated, so further improvement is needed. Utility Model Content

[0004] This utility model discloses a rapid cleaning device for boilers in thermal power plants, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rapid cleaning device for a thermal power plant boiler includes a cleaning unit and a water suction unit.

[0007] The cleaning unit includes a hydraulic cylinder and a brush plate. A motor is fixedly installed at one end of the hydraulic cylinder, and an installation plate is fixedly installed on the outer wall of the motor. A spring tube is fixedly connected to one side of the brush plate, and a spring telescopic rod is fixedly installed on one side of the brush plate. A brush is fixedly installed on the other side of the brush plate away from the spring tube, and a spray head is fixedly connected to one side of the brush plate.

[0008] The water suction unit includes a water pump, a water pipe fixedly installed at the output end of the water pump, a water storage plate rotatably connected to one end of the water pipe, a first electric valve fixedly installed on the outer wall of the water pipe, a suction pipe fixedly connected to the bottom of the water pipe, a second electric valve fixedly installed on the outer wall of the suction pipe, a suction base fixedly connected to the bottom of the suction pipe, and the water pipe rotatably connected to the bottom of the water storage plate.

[0009] In a preferred embodiment, a bearing is rotatably mounted on the outer wall of the mounting plate, and the outer wall of the bearing is slidably mounted with the brush plate.

[0010] In a preferred embodiment, the end of the spring tube away from the brush plate is fixedly connected to the connecting water storage plate, and the end of the spring telescopic rod away from the brush plate is fixedly installed on the connecting water storage plate.

[0011] In a preferred embodiment, a mounting plate is fixedly installed at the bottom of the hydraulic cylinder, and an expansion bolt is inserted into the mounting plate of the hydraulic cylinder.

[0012] In a preferred embodiment, the motor output end is fixedly installed on the top of the water storage plate, and the water pipe is elastic.

[0013] In a preferred embodiment, the outer wall of the water-absorbing chassis is provided with a plurality of water-absorbing grooves, and the second electric valve is fixedly installed on the top of the water-absorbing chassis.

[0014] As can be seen from the above, the rapid cleaning device for thermal power plant boilers provided by this utility model has the following technical effects.

[0015] Firstly, the motor is lowered by a hydraulic cylinder, allowing the brush plate to enter the boiler. The motor drives the connected water storage plate to rotate, which in turn drives the brush to rotate inside the boiler, scrubbing the inner wall of the boiler. The spring return force of the spring telescopic rod allows the brush to fit tightly against the boiler. Even after the brush shortens due to prolonged use, it can still complete the cleaning work.

[0016] Secondly, during the cleaning process, a mixture of water and cleaning solution is pumped into the water pipe. The water enters the water storage plate through the water pipe, then passes through the spring tube and brush plate into the brush, and is sprayed out through the nozzle. This works in conjunction with the brush to clean the boiler. After cleaning, the first electric valve is closed and the second electric valve is opened, driving the water pump to output in the opposite direction. The dirty water inside the boiler is sucked out through the suction plate. The water spraying is used to assist in the cleaning process. There is no need for manual pouring of water into the boiler, which is convenient and quick. At the same time, the dirty water can be sucked out after cleaning, which has a high degree of automation and eliminates the need for manual water pumping. Attached Figure Description

[0024] Reference Figures 1-4 A rapid cleaning device for a thermal power plant boiler includes a cleaning unit 100 and a water suction unit 200.

[0025] The cleaning unit 100 includes a hydraulic cylinder 101 and a brush plate 105. The hydraulic cylinder 101 can quickly pull the device out of the boiler. A motor 102 is fixedly installed at one end of the hydraulic cylinder 101, which provides rotational power. An installation plate 103 is fixedly installed on the outer wall of the motor 102. A spring tube 106 is fixedly connected to one side of the brush plate 105. A spring telescopic rod 107 is fixedly installed on one side of the brush plate 105, which provides rebound force to stabilize the position of the brush 108. A brush 108 is fixedly installed on the other side of the brush plate 105 away from the spring tube 106. A nozzle 109 is fixedly connected to one side of the brush plate 105, which sprays water to assist in cleaning.

[0026] The water suction unit 200 includes a water pump 201, a water pipe 202 fixedly installed at the output end of the water pump 201, a water storage plate 203 rotatably connected to one end of the water pipe 202, a first electric valve 204 fixedly installed on the outer wall of the water pipe 202, a suction pipe 205 fixedly connected to the bottom of the water pipe 202, a second electric valve 206 fixedly installed on the outer wall of the suction pipe 205, and a suction base 207 fixedly connected to the bottom of the suction pipe 205.

[0027] In this embodiment, during the cleaning process, a mixture of water and cleaning solution is input into the water pipe 202 via the water pump 201. The water enters the water storage plate 203 through the water pipe 202, then enters the brush 108 through the spring tube 106 and the brush plate 105, and is sprayed out through the nozzle 109. This works in conjunction with the brush 108 to clean the boiler. After cleaning, the first electric valve 204 is closed and the second electric valve 206 is opened, driving the water pump 201 to output in the opposite direction. The dirty water inside the boiler is sucked out through the suction plate 207. The cleaning is carried out by spraying water, eliminating the need for manual pouring of water into the boiler. This is convenient and quick, and the dirty water can be sucked out after cleaning, resulting in a high degree of automation and eliminating the need for manual water pumping.

[0028] In a preferred embodiment, a bearing 104 is rotatably mounted on the outer wall of the mounting plate 103, and the outer wall of the bearing 104 is slidably mounted on the brush plate 105.

[0029] In this embodiment, the position of the motor 102 is further stabilized by the bearing 104 and the mounting plate 103 to prevent the motor 102 and the hydraulic cylinder 101 from separating under the long-term influence of gravity.

[0030] In a preferred embodiment, the end of the spring tube 106 away from the brush plate 105 is fixedly connected to the connecting water storage plate 203, and the end of the spring telescopic rod 107 away from the brush plate 105 is fixedly installed on the connecting water storage plate 203.

[0031] In this embodiment, the spring telescopic rod 107 provides a rebound force, so that the brush 108 always adheres to the inner wall of the boiler.

[0032] In a preferred embodiment, a mounting plate is fixedly installed at the bottom of the hydraulic cylinder 101, and an expansion bolt is inserted into the mounting plate of the hydraulic cylinder 101.

[0033] In this embodiment, expansion bolts are drilled into the ground, which makes the installation of hydraulic cylinder 101 very stable.

[0034] In a preferred embodiment, the output end of the motor 102 is fixedly installed on the top of the water storage plate 203, and the water pipe 202 is elastic.

[0035] In this embodiment, the motor 102 drives the water storage plate 203 to rotate, and the water storage plate 203 is located at the center of the device, so the motor 102 can drive the device to rotate.

[0036] In a preferred embodiment, the outer wall of the water-absorbing chassis 207 is provided with a plurality of water-absorbing grooves, and the second electric valve 206 is fixedly installed on the top of the water-absorbing chassis 207.

[0037] In this embodiment, the water-absorbing base 207 is located at the bottom of the device, which enables the dirty water to be sucked out immediately and ensures the efficiency of the suction when dirt settles.

[0038] Working principle: When in use, the motor 102 is first lowered by the hydraulic cylinder 101, so that the brush plate 105 enters the boiler. The motor 102 drives the water storage plate 203 to rotate, thereby driving the brush 108 to rotate inside the boiler and brush the inner wall of the boiler. The spring return force of the spring telescopic rod 107 can make the brush 108 fit tightly with the boiler.

[0039] During the cleaning process, a mixture of water and cleaning solution is introduced into the water pipe 202 by the water pump 201. The water enters the water storage plate 203 through the water pipe 202, and then enters the brush 108 through the spring tube 106 and the brush plate 105. It is then sprayed out through the nozzle 109, working with the brush 108 to clean the boiler.

[0040] After cleaning is completed, the first electric valve 204 is closed and the second electric valve 206 is opened, and the water pump 201 is driven to output in reverse, sucking out the dirty water inside the boiler through the suction chassis 207.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Substitutions may include replacements for some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the scope of protection of this utility model.
