Description

Technical Field

[0001] The invention relates to the field of pipeline descaling devices, and in particular to a jet descaling device. Background Art

[0002] In industry and daily life, the transportation of various fluid media is mainly completed by steel pipes, including sewage, clean water, oil and water, and crude oil. After a period of use, the inner wall of the pipe forms dirt due to the adhesion and deposition of the transported liquid, which reduces the diameter of the steel pipe, increases the transport resistance, and reduces the transport capacity. It is necessary to use a jet descaling device to clean the steel pipe regularly;

[0003] However, conventional jet descaling devices can only clean horizontally placed pipes, but are difficult to clean vertical pipes. To address the above problems, a cleaning device for cleaning the inner wall of a vertical oil pipe (publication number: CN109047211A) is provided in the prior art. High-pressure water is injected into the oil pipe through a casing to clean and descale the inner wall of the vertical oil pipe with a cavitation jet, which has good cleaning effect and fast cleaning speed.

[0004] However, in actual use of the above technical solution, for a long pipeline, the cleaning water flows into the pipeline during the cleaning process, and it is difficult to recycle the cleaning water. At the same time, the thickness of the dirt in different places in the pipeline varies. The flow rate of the water jet from the sleeve in the above solution is a fixed value, which makes it difficult to completely clean thicker dirt, and it will cause a waste of resources for thinner dirt. It is difficult to achieve adaptive adjustment of the jet according to the thickness of the dirt.

[0005] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0017] The beneficial effects of the present invention are as follows:

[0018] (1) The present invention is to put the vertical rod into the pipeline vertically. At this time, the airbag 1 is in contact with the inner wall of the pipeline. Cleaning water is input into the vertical rod through the water inlet pipe, and then sprayed out through the nozzles on the fixed cavity 1 and the fixed cavity 2 to flush the inner wall of the pipeline.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figure 1 - Figure 4As shown, this embodiment is a jet descaling device, including a vertical rod 1, one end of which is connected to a water inlet pipe 101, a fixed cavity 102 and a fixed cavity 2 103 are fixedly installed at the bottom of the vertical rod 1, a nozzle 104 is fixedly installed on the fixed cavity 102 and the fixed cavity 2 103, and a collecting component 2 is fixedly installed at the bottom of the fixed cavity 2 103 of the vertical rod 1.

[0032] The collecting component 2 includes a fixed plate 201 and an airbag 202. The fixed plate 201 is fixedly connected to the fixed cavity 2 103. A plurality of fixed grooves 203 are provided on the outer wall of the fixed plate 201. The airbag 202 is fixedly installed in the fixed groove 203. Three groups of airbags 202 are arranged. The three groups of airbags 202 are evenly spaced on the outer wall of the fixed plate 201. The three groups of airbags 202 can ensure the sealing performance and prevent the cleaning water from leaking. At the same time, the three groups of airbags 202 can more comprehensively cover the entire inner wall of the pipeline.

[0033] The cleaning water and dirt mixture flows to the filter plate 209 under the action of gravity, and is filtered by the filter plate 209. The dirt remains on the filter plate 209, and the liquid flows into the collection tank 208, wherein the drain pipe 210 is connected to a pumping device, and the liquid in the collection tank 208 is extracted and recovered by the pumping device.

[0034] Specifically, the vertical rod 1 is placed vertically into the pipe. At this time, the airbag 1 202 is in contact with the inner wall of the pipe. Cleaning water is input into the vertical rod 1 through the water inlet pipe 101, and then sprayed out through the nozzles 104 on the fixed cavity 102 and the fixed cavity 2 103 to flush the inner wall of the pipe. During the cleaning process, the cleaning water flows downward and is filtered and stored in the collection tank 208. At this time, the cleaning water in the collection tank 208 is extracted through the drain pipe 210, which effectively prevents the cleaning water from flowing into the pipe. At the same time, the cleaning water is filtered and recovered, thereby realizing the recycling of the cleaning water.

[0035] Example 2: Please refer to Figure 5 - Figure 8 As shown, the present invention also includes a moving rod 1 204, a moving rod 205 and a baffle 206. The moving rod 1 204 is movably installed in the fixed cavity 2 103, and the moving rod 205 is movably installed in the fixed cavity 1 102. The moving rod 1 204 and the moving rod 205 are both against the baffle 206. The baffle 206 is movably installed in the fixed cavity 102 and the fixed cavity 2 103. A through hole 207 is opened on the baffle 206. The position of the through hole 207 corresponds to the position of the nozzle 104. The cleaning water enters the vertical rod 1 through the water inlet pipe 101, and then enters the nozzle 104 after passing through the through hole 207. The through hole 207 is used to convert the cleaning water into a high-speed jet, and the dirt is removed by the impact force of the jet.

[0036] A collecting groove 208 is opened at the center of the fixed plate 201, and a filter plate 209 is fixedly installed in the collecting groove 208. A drain pipe 210 is fixedly installed on the fixed plate 201, a fixed tube 1 211 is fixedly installed inside the fixed chamber 2 103, a movable rod 1 204 is movably installed in the fixed tube 1 211, an airbag 2 212 is fixedly installed in the fixed tube 1 211, the airbag 212 is fixedly connected to the airbag 1 202 through a pipeline, an annular plate 213 is fixedly installed on the outer wall of the fixed chamber 2 103, an adjusting plate 214 is movably installed in the annular plate 213, and the adjusting plate 214 is fixedly connected to the baffle 206 in the fixed chamber 2 103.

[0037] An airbag three 215 is fixedly installed in the annular plate 213, and the airbag three 215 is fixedly connected to the adjustment plate 214. A fixed tube two 216 is fixedly installed in the fixed cavity 102. The movable rod two 205 is movably installed in the fixed tube two 216. An airbag four 217 is fixedly installed in the fixed tube two 216. The airbag three 215 is fixedly connected to the airbag four 217 through a pipeline, that is, the airbag two 212 is controlled by the airbag one 202, and the baffle 206 in the fixed cavity two 103 is controlled by the movable rod one 204. The baffle 206 in the fixed cavity two 103 is used to push the adjustment plate 214 to move, and then the airbag three 215 is used to control the airbag four 217. Through the linkage between multiple structures, the synchronous control of the baffle 206 is realized.

[0038] A spring is fixedly installed inside airbag 1 202, and the spring is fixedly connected to the inner wall of airbag 1 202. An air inlet pipe 218 is fixedly installed at the bottom of airbag 1 202, and a one-way valve 1 is fixedly installed in the air inlet pipe 218. A one-way valve 2 is fixedly installed at the connection between airbag 1 202 and airbag 2 212. When airbag 1 202 is squeezed and contracted, the gas in airbag 1 202 enters airbag 2 212, and both one-way valve 1 and one-way valve 2 are used to control the direction of gas flow.

[0039] When the gas enters airbag two 212 from airbag one 202, the one-way valve two is in an open state. When the gas enters airbag one 202 from airbag two 212, the one-way valve two is in a closed state to prevent the gas from flowing back. The spring in airbag one 202 is used to restore airbag one 202. Airbag one 202 expands under the action of the spring, and at the same time, air is drawn into airbag one 202 through the bottom air inlet pipe 218. During the movement of airbag one 202, the volume of airbag one 202 will change multiple times, which will cause multiple streams of gas to enter airbag two 212. The amount of gas accumulated in airbag two 212 indicates the amount of dirt in this direction.

[0040] At the same time, after the vertical rod 1 is placed in place, the airbag 202 expands under the action of the spring, and the airbag 202 is against the inner wall of the pipe, thereby fixing the position of the fixed plate 201, improving the stability of the jet descaling process, saving more effort, and effectively improving the descaling efficiency.

[0041] A spring is fixedly installed in the annular plate 213, and two ends of the spring are fixedly connected to the inner wall of the annular plate 213 and the adjusting plate 214 respectively. When the airbag 212 expands, it drives the baffle 206 in the fixed chamber 103 to move upward, and then the baffle 206 drives the adjusting plate 214 to move upward. At this time, the airbag 3 215 is squeezed, and the gas enters the airbag 4 217, driving the airbag 4 217 to expand, thereby driving the moving rod 205 to move upward, and then pushing the baffle 206 in the fixed chamber 102 to move upward, thereby realizing the synchronous adjustment of the fixed chamber 102 and the fixed chamber 2 103.

[0042] When the vertical rod 1 is placed into the pipeline, the airbag 1 202 and the inner wall of the pipeline are squeezed against each other. After the squeezing, the gas in the airbag 1 202 enters the fixed cavity 2 103. In the area where the dirt is thicker, the airbag 1 202 is squeezed more heavily, and the volume of the flowing gas is larger. In the area where the dirt is thinner, the airbag 1 202 is squeezed less heavily, and the volume of the flowing gas is smaller. The moving distance of the moving rod 1 204 and the moving rod 205 is controlled according to the gas volume, and the baffle 206 is lifted by the moving rod 1 204 and the moving rod 205 to adjust the position of the through hole 207, thereby controlling the water inlet cross section of the nozzle 104 in different areas, thereby realizing adaptive adjustment of the jet.

[0043] Combining Example 1 and Example 2, it can be known that the cleaning water in the collection tank 208 is extracted through the drain pipe 210, which effectively prevents the cleaning water from flowing into the pipe. At the same time, the cleaning water is filtered and recovered to achieve the recycling of the cleaning water. At the same time, the position of the baffle 206 is adjusted by changing the squeezing degree of the airbag 202, so as to adjust the position of the through hole 207, and then control the water inlet cross section of the nozzle 104 in different areas, so as to achieve adaptive adjustment of the jet.

[0044] The working process and principle of the present invention are as follows:

[0045] First, washing water is input into the vertical rod 1 through the water inlet pipe 101 to flush the inner wall of the pipe. During the washing process, the washing water flows downward and is filtered and stored in the collection tank 208. At this time, the washing water in the collection tank 208 is extracted through the drain pipe 210, which effectively prevents the washing water from flowing into the pipe. At the same time, the washing water is filtered and recovered, realizing the recycling of the washing water.

[0046] Furthermore, by changing the squeezing degree of the airbag 1 202, the position of the baffle 206 is adjusted, thereby adjusting the position of the through hole 207, and then controlling the water inlet cross section of the nozzle 104 in different areas, thereby realizing adaptive adjustment of the jet;

[0047] In summary, the present invention realizes adaptive adjustment of the jet while realizing the recovery of cleaning water.
