Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and more specifically, to an industrial cleaning machine for nuclear power pipe materials. Background Art

[0002] With the rapid development of the nuclear power industry, large nuclear power pipe materials play a crucial role in the construction and operation of nuclear power plants. These pipe materials are usually used to transport coolants, steam or other key fluids, and the cleanliness of their inner walls directly affects the safety, operation efficiency and service life of nuclear power plants. However, due to the structural characteristics of large diameter and long length of nuclear power pipe materials, traditional cleaning methods are difficult to meet their high-precision and high-efficiency cleaning requirements.

[0003] At present, the cleaning of nuclear power pipe materials mainly relies on methods such as chemical cleaning, high-pressure water jet cleaning or mechanical brushing. These methods have the following deficiencies: Although chemical cleaning can effectively remove surface dirt, it often involves the use of a large amount of chemical reagents, which may cause environmental pollution, and the cost of treating the waste liquid after cleaning is relatively high. Chemical reagents may also corrode the surface of the pipe materials, affecting their long-term use performance; High-pressure water jet cleaning can remove some stubborn dirt, but the removal effect on tiny particles or oil-based pollutants on the inner wall of the pipe materials is limited, and the high-pressure water flow may cause mechanical damage to the inner wall of the pipe materials; Mechanical brushing removes dirt through physical friction. It is difficult for the brushing tools to completely cover all areas, and the operation efficiency is low, unable to meet the requirements of large-scale production. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above deficiencies of the prior art and provide an industrial cleaning machine for nuclear power pipe materials.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The present invention discloses an industrial cleaning machine for nuclear power pipe materials, which includes a cleaning tank.

A first annular groove is formed on the outer periphery of the connecting block, and a second annular groove corresponding to the first annular groove is arranged on the inner periphery of the rotating ring. A liquid supply hole is connected between the second annular groove and the annular cavity. Two sealing rings are arranged between the rotating ring and the connecting block, and the two sealing rings are respectively located on both sides of the first annular groove and the second annular groove; a submersible pump is arranged on the moving block, a communicating hole is formed on the moving block, the outlet end of the submersible pump is communicated with the communicating hole, a liquid inlet hole is formed in the connecting block, one end of the liquid inlet hole is communicated with the communicating hole, and the other end of the liquid inlet hole is communicated with the first annular groove.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Such as Figures 1 - 10As shown in the figure, a nuclear power pipe industrial cleaning machine includes a cleaning tank 3, an in - inserted cleaning mechanism 2, a cleaning liquid distillation mechanism 4, a storage mechanism 5, a vacuum pump 6, a waste liquid tank 7, a box body 8, a drying air supply mechanism 9, a waste water storage tank 10, and a liquid supply pump 11. The cleaning liquid distillation mechanism 4 includes a distillation purifier 401 and a distillation storage tank 402. The distillation storage tank 402 is connected to the storage mechanism 5, the vacuum pump 6, and the distillation purifier 401 through pipelines. The distillation purifier 401 is connected to the cleaning tank 3 through a pipeline. The cleaning tank 3 is connected to the waste water storage tank 10 through a pipeline. The drying air supply mechanism 9 introduces external air into the cleaning tank 3 for use in blowing during the drying stage. The liquid supply pump 11 is connected to the cleaning liquid spray pipe 202 through a pipeline for injecting the cleaning liquid into the cleaning tank 3. The waste liquid tank 7 is connected to the cleaning liquid distillation mechanism 4 through a pipeline.

[0028] As Figure 3 shown in the figure, the in - inserted cleaning mechanism 2 is arranged inside the cleaning tank 3. The in - inserted cleaning mechanism 2 includes a pipe limiting mechanism 203. The pipe limiting mechanism 203 includes two groups of clamping blocks 2031. Each group of clamping blocks 2031 is driven by an external driving mechanism so that the two groups of clamping blocks 2031 move relatively closer or farther away from each other. The nuclear power pipe 1 is clamped and fixed inside the cleaning tank 3 by the two groups of clamping blocks 2031.

[0029] As Figure 4 shown in the figure, a track fixing mechanism 204 and a transmission mechanism 201 are respectively arranged at both ends of the pipe limiting mechanism 203. There is a certain distance between both ends of the fixed nuclear power pipe 1 and the track fixing mechanism 204 and the transmission mechanism 201 respectively.

[0030] The transmission mechanism 201 is located on one side close to the opening of the cleaning tank 3; the in - inserted cleaning mechanism 2 further includes a rod - type track 205. The rod - type track 205 is located between the track fixing mechanism 204 and the transmission mechanism 201. The rod - type track 205 is conveyed from the transmission mechanism 201 to the side of the track fixing mechanism 204, so that the rod - type track 205 passes through the nuclear power pipe 1, and the rod - type track 205 enters the track fixing mechanism 204 for limiting and supporting.

[0031] As Figure 5 shown in the figure, a moving block 207 is installed on the rod - type track 205. The moving block 207 can move back and forth on the rod - type track 205. An ultrasonic rotary cleaning mechanism 209 is installed on the moving block 207. Through the ultrasonic rotary cleaning mechanism 209 for ultrasonic vibration and high - pressure rotary spraying, the stubborn dirt on the inner wall of the pipe is removed, realizing the deep cleaning of the inner wall of the nuclear power pipe 1. The ultrasonic rotary cleaning mechanism 209 does not contact the nuclear power pipe 1 to avoid secondary pollution.

[0032] After fixing the nuclear power pipe on the pipe limiting mechanism 203 and threading the rod-shaped track 205 inside, the whole pipe limiting mechanism 203 is then transported into the cleaning tank 3 to clean the nuclear power pipe.

[0033] As the end of the rod-shaped track 205 moves away from the transmission mechanism 201, it will droop under the influence of gravity and will not be able to accurately enter the track fixing mechanism 204. As Figure 6 shown, by installing a track moving bracket 206 at the lower part of the rod-shaped track 205 on the side close to the track fixing mechanism 204 to support the end of the moving rod-shaped track 205, the position of the end of the rod-shaped track 205 will not change and it can be accurately inserted into the track fixing mechanism 204.

[0034] The track moving bracket 206 includes a fixing block 2061 installed at the lower part of the rod-shaped track 205. At least two mounting arms 2064 are installed under the fixing block 2061. A roller 2063 is rotatably arranged at one end of the mounting arm 2064 away from the fixing block 2061, and the roller 2063 contacts the inner wall of the nuclear power pipe 1. The track moving bracket 206 also includes several support arms 2062. A mounting seat 2068 is installed under the fixing block 2061. One end of the support arm 2062 is installed on the mounting seat 2068 through a fixing bolt 2069, and this installation method makes the installation angle of the support arm 2062 adjustable.

[0035] A groove is opened on one side of the support arm 2062 away from the mounting seat 2068. Oval holes 2067 are opened at the positions on both sides of the groove of the support arm 2062, and the oval holes 2067 communicate with the groove. An adjusting arm 2065 is connected to the side of the mounting arm 2064 close to the fixing block 2061. The adjusting arm 2065 is located in the groove. A fixing screw two 2066 is connected to the side of the adjusting arm 2065. The fixing screw two 2066 passes through the oval hole 2067. The part of the fixing screw two 2066 passing through the oval hole 2067 is threadedly connected with a nut. The length of the adjusting arm 2065 inserted into the groove is adjustable, so that the distance between the roller 2063 and the fixing block 2061 is adjustable. The adjustable installation can be applicable to nuclear power pipes 1 with different diameters.

[0036] After the end of the rod-shaped track 205 enters the track fixing mechanism 204, the rod-shaped track 205 moves a certain distance further so that the track moving bracket 206 leaves the nuclear power pipe 1 and the track moving bracket 206 does not contact the nuclear power pipe 1.

[0037] As Figures 9 - 10As shown, the track fixing mechanism 204 includes a mounting frame 2041. A limiting frame 2042 is arranged inside the mounting frame 2041. Fixed screw rods I 2043 are connected to both sides of the limiting frame 2042. Strip-shaped holes are formed on both sides of the mounting frame 2041. The strip-shaped holes are arranged along the length direction of the mounting frame 2041. The fixed screw rods I 2043 pass through the strip-shaped holes. Nuts are threadedly connected to the parts of the fixed screw rods I 2043 that penetrate out of the long strip holes. The transmission mechanism 201 includes a support frame 2011. A limiting strip 2012 is installed on the side surface of the support frame 2011. The limiting strip 2012 is arranged along the length direction of the support frame 2011. A support plate 2013 is arranged inside the support frame 2011. A conveying roller 2014 is rotatably arranged on the upper part of the support plate 2013. A conveying motor 2015 and a speed reducer 2016 are arranged on the lower part of the support plate 2013. The conveying motor 2015 and the speed reducer 2016 are drivingly connected. The speed reducer 2016 and the conveying roller 2014 are driven by belt drive. Blocks 2017 are arranged at positions corresponding to both sides of the limiting strip 2012 on the lower part of the support plate 2013. Fastening screws 2018 are threadedly connected to the blocks 2017. The fastening screws 2018 abut against the limiting strip 2012 from both sides, thereby completing the fixation of the support plate 2013.

[0038] For nuclear power pipes 1 with different diameters, the heights of the support plate 2013 and the limiting frame 2042 are adjusted accordingly, so that the rod-shaped track 205 can be located at the center of the nuclear power pipe 1, and thus the ultrasonic rotary cleaning mechanism 209 is located near the center of the nuclear power pipe 1, and the cleaning effect on each part of the inner wall of the nuclear power pipe 1 can be kept consistent.

[0039] A connecting block 208 is installed on the moving block 207. The ultrasonic rotary cleaning mechanism 209 includes a transducer 2099 and a rotating ring 2091. The transducer 2099 is installed on the moving block 207. The rotating ring 2091 is rotatably arranged on the connecting block 208. A bearing 2093 is arranged between the rotating ring 2091 and the connecting block 208. A plurality of nozzles 2092 are arranged on the outer periphery of the rotating ring 2091. The rod-shaped track 205 passes through the rotating ring 2091.

[0040] An annular cavity 20911 is provided inside the rotating ring 2091. Liquid outlet holes 20912 are provided on the outer periphery of the annular cavity 20911 corresponding to the positions of the spray nozzles 2092. The liquid outlet holes 20912 communicate the spray nozzles 2092 and the annular cavity 20911. A first annular groove 2082 is formed on the outer periphery of the connecting block 208. A second annular groove 20914 corresponding to the first annular groove 2082 is provided on the inner periphery of the rotating ring 2091. A liquid supply hole 20913 is connected between the second annular groove 20914 and the annular cavity 20911. Two sealing rings 20915 are provided between the rotating ring 2091 and the connecting block 208. The two sealing rings 20915 are respectively located on both sides of the first annular groove 2082 and the second annular groove 20914. When the rotating ring 2091 rotates on the connecting block 208, the sealing rings 20915 can prevent the cleaning liquid from leaking from the chamber formed by the first annular groove 2082 and the second annular groove 20914.

[0041] A submersible pump 2094 is provided on the moving block 207. A communication hole 2073 is formed on the moving block 207. The outlet end of the submersible pump 2094 is communicated with the communication hole 2073. A liquid inlet hole 2081 is formed in the connecting block 208. One end of the liquid inlet hole 2081 is communicated with the communication hole 2073, and the other end of the liquid inlet hole 2081 is communicated with the first annular groove 2082. After the submersible pump 2094 pumps in the cleaning liquid, the cleaning liquid is pumped into the chamber formed by the first annular groove 2082 and the second annular groove 20914 through the communication hole 2073 and the liquid inlet hole 2081. The cleaning liquid then enters the annular cavity 20911 through the liquid supply hole 20913 and is finally sprayed out from the spray nozzles 2092 through the liquid outlet holes 20912. High-frequency vibration is generated by the transducer, causing the tiny bubbles in the cleaning liquid to burst rapidly, generating an impact force to peel off the stains on the inner wall. The spray nozzles can spray the cleaning liquid to wash away the dirt.

[0042] The rod-shaped track 205 includes a rack 2051, and the rack 2051 is arranged along the length direction of the rod-shaped track 205. A submersible motor 2072 is provided on the moving block 207. The submersible motor 2072 is drivingly connected with a driving gear 2071, and the driving gear 2071 meshes with the rack 2051. By driving the driving gear 2071 to rotate forward and backward by the submersible motor 2072, the moving block 207 is driven to move back and forth on the rod-shaped track 205.

[0043] The setting direction of the spray nozzles 2092 is not along the radial direction of the rotating ring 2091, but the included angle between the axial direction of the spray nozzles 2092 and the radial direction of the rotating ring 2091 is set to 45 to 60 degrees, so that the cleaning liquid sprayed from the spray nozzles 2092 can drive the rotating ring 2091 to rotate, and the sprayed cleaning liquid forms a turbulent flow to wash away the dirt inside the large nuclear power pipe 1.

[0044] Another way to rotate the rotating ring 2091 is that a support frame 2095 is installed in the connecting block 208. A worm gear 2096 and a worm 2097 are respectively rotatably arranged on the support frame 2095. The axes of the worm gear 2096 and the worm 2097 are perpendicular to each other. The worm 2097 is coaxially connected with a transmission gear, and the transmission gear meshes with the rack 2051. A toothed ring 2098 is arranged in the rotating ring 2091, and the worm gear 2096 meshes with the toothed ring 2098. When the moving block 207 moves on the rod-shaped track 205, the transmission gear will rotate under the action of the rack 2051, and then drive the coaxial worm 2097 to rotate. The worm 2097 acts on the worm gear 2096, and the worm gear 2096 then acts on the toothed ring 2098, thereby driving the rotating ring 2091 to rotate, so that the cleaning liquid sprayed from the nozzle 2092 forms a turbulent flow, enhancing the cleaning effect.

[0045] The submersible pump 2094 and the submersible motor 2072 are powered by a battery and ensure good sealing performance.

[0046] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
