Description

Technical Field

[0001] The present application relates to the technical field of pipeline coke cleaning, and in particular to a novel series-type anti-reversal coke cleaning ball. Background Art

[0002] The working principle of furnace tube de-coking is to rely on water flow to push the de-coking ball to move back and forth from one end to the other end in the furnace tube. When the furnace tube has a variable diameter, when the smaller de-coking ball enters the furnace tube with a larger diameter from the furnace tube with the corresponding diameter, it may roll over under the drive of the water flow. The overturned de-coking ball will be stuck vertically in the furnace tube, causing the furnace tube to be blocked, which not only affects the progress of pipeline de-coking, but also makes it extremely difficult to remove the de-coking ball stuck in the pipe. Sometimes, in order to remove the de-coking ball stuck in the pipe, it is necessary to reversely flush the furnace tube, which will cause secondary pollution to the cleaned thin-diameter furnace tube, causing greater losses. Summary of the invention

[0003] The present application provides a novel series-type anti-reversal coke cleaning ball. A series connection device is installed at the end of the coke cleaning ball, and two coke cleaning balls can be connected together through the series connection device. During the cleaning process, the series-type coke cleaning balls can grind the coke blocks on the tube wall more fully. After entering the variable diameter, the two coke cleaning balls are connected to each other, which avoids the situation where the coke cleaning ball is vertically stuck in the furnace tube, and can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a new type of serial anti-reversal defocusing ball, comprising a defocusing ball; a scraping area is provided in the middle of the outer surface of the defocusing ball, and raised metal particles are evenly distributed on the scraping area, and serial connection devices are provided at both ends of the defocusing ball.

[0005] The serial connection device includes a positioning plate arranged inside the decoking sphere, the end of the positioning plate is rotatably connected to a rotating body, the outer side of the rotating body is provided with two internal threaded sleeves, the internal threads of the internal threaded sleeves are connected to screws, and the two screws located on the same side of the outer surface of the decoking sphere are connected together by a cable.

[0006] Preferably, no less than two metal particles form a spiral array band, and the spiral array band is evenly distributed in the scraping area at equal intervals.

[0007] Preferably, the outer side surface of the positioning plate is provided with at least one fork rod.

[0008] Preferably, an ear plate is provided at the end of the screw rod, and the ear plate is connected to the cable.

[0009] Preferably, a cylindrical rubber plug is inserted into the interior of the internally threaded sleeve.

[0010] Compared with the prior art, the beneficial effects of this application are:

[0011] 1. The new series-type anti-reversal coke cleaning ball has a series connection device installed at the end of the coke cleaning ball, through which two coke cleaning balls can be connected together. During the cleaning process, the series-type coke cleaning ball grinds the coke blocks on the tube wall more fully. After entering the variable diameter, the two coke cleaning balls are connected to each other, which avoids the situation where the coke cleaning ball is vertically stuck in the furnace tube;

[0012] 2. When cleaning the furnace tube, insert the cleaning ball into the furnace tube. The cleaning ball moves along the pipe under the impact of the water flow. At this time, the metal particles arranged on the outer surface of the cleaning ball scrape and clean the inside of the pipe. When the furnace tube has a variable diameter, two or more cleaning balls are connected in series through a series connection device, which can effectively prevent the cleaning ball from getting stuck in the furnace tube.

[0013] 3. When connecting the defocusing balls in series, unscrew the screw, cross the cables at the ends of the two defocusing balls, and then screw the screw into the inner threaded sleeve again. At this time, the two defocusing balls can be connected together through the crossed cables. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] In the description of this application, when a feature is referred to as being "set", "fixed" or "connected" to another feature, it may be directly set, fixed or connected to the other feature, or indirectly set, fixed or connected to the other feature.

[0022] See also Figure 1-5 The present application provides the following technical solutions: a new type of serial anti-reversal defocusing ball, comprising a defocusing ball 2; a scraping area is provided in the middle of the outer surface of the defocusing ball 2, and raised metal particles 3 are evenly distributed on the scraping area, and serial connection devices 4 are provided at both ends of the defocusing ball 2.

[0023] Specifically, when cleaning the pipeline, the cleaning ball 2 is inserted into the pipe fitting, and the cleaning ball 2 moves along the pipe fitting under the impact of the water flow. At this time, the metal particles 3 arranged on the outer surface of the cleaning ball 2 scrape and clean the inside of the pipe fitting.

[0024] More specifically, when the furnace tube has a variable diameter, two or more decoking balls 2 are connected in series by the series connection device 4, which can effectively prevent the decoking balls 2 from getting stuck in the furnace tube.

[0025] The serial connection device 4 includes a positioning plate 45 arranged inside the decoking sphere 2, and the end of the positioning plate 45 is rotatably connected to a rotating body 47. The outer side of the rotating body 47 is provided with two internal threaded sleeves 44, and the internal threads of the internal threaded sleeves 44 are connected to a screw 43. The two screws 43 located on the same side of the outer surface of the decoking sphere 2 are connected together by a cable 42.

[0026] Specifically, when connecting the decoking spheres 2 in series, unscrew the screw 43, then cross the cables 42 at the ends of the two decoking spheres 2 and screw the screw 43 into the inner threaded sleeve 44 again. At this time, the two decoking spheres 2 can be connected together through the crossed cables 42.

[0027] Furthermore, at least two metal particles 3 form a spiral array band, and the spiral array band is evenly distributed in the scraping area at equal intervals.

[0028] Specifically, when the decoking sphere 2 rotates in the pipeline, the spiral array belt can rub the inner wall of the pipeline in all directions, thereby achieving thorough cleaning of the inner wall of the pipeline.

[0029] Furthermore, at least one fork rod 46 is disposed on the outer side of the positioning plate 45 .

[0030] Specifically, the fork rod 46 can make the positioning plate 45 and the defocusing sphere 2 tightly combined together, thereby increasing the tensile strength of the positioning plate 45 .

[0031] Furthermore, a lug plate 41 is provided at the end of the screw rod 43 , and the lug plate 41 is connected to the cable 42 .

[0032] Specifically, the end of the ear plate 41 is rotatably connected to the cable 42 , and the cable 42 will not get tangled when the ear plate 41 rotates. The arrangement of the ear plate 41 facilitates the installation and removal of the screw rod 43 .

[0033] Furthermore, a cylindrical rubber plug 1 is inserted into the inner threaded sleeve 44 .

[0034] Specifically, when the decoking sphere 2 is used alone, the cylindrical rubber plug 1 is inserted into the internal threaded sleeve 44 , which can effectively prevent dirt from entering the interior of the internal threaded sleeve 44 .

[0035] When in use: when the furnace tube has a variable diameter, two or more decoking balls 2 are connected in series through the series connection device 4 .

[0036] When connecting the decoking spheres 2 in series, unscrew the screw 43, then cross the cables 42 at the ends of the two decoking spheres 2 and screw the screw 43 into the inner threaded sleeve 44 again. At this time, the two decoking spheres 2 can be connected together through the crossed cables 42.

[0037] Then, the decoking balls 2 connected in series are sent into the furnace tube. When the diameter changes, the decoking balls 2 connected in series pull each other, which can effectively prevent the decoking balls 2 from getting stuck in the furnace tube.

[0038] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
