Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline cleaning devices, and in particular relates to a pipeline high-pressure flushing nozzle. Background Art

[0002] Whether it is a water-coal slurry or dry coal powder gasifier, the synthetic gas pipeline from the gasifier to the carbon washing tower will have resistance caused by pipeline scaling after the coal quality fluctuates and after the gasifier has been running for a period of time. Once the pipeline scaling begins to form, the resistance will continue to increase. If no measures are taken to stabilize the pipeline resistance, the quenching water flow rate will slowly decrease or fluctuate, and the furnace pressure will be forced to increase accordingly. The quenching water flow rate is an important indicator during the operation of the gasifier. Therefore, after running for a period of time, it is necessary to remove the scaling inside the pipeline. Pipeline scaling removal usually adopts high-pressure flushing. The operator needs to hold the high-pressure water pipe and go deep into the pipeline for flushing. Since the nozzle is a high-pressure nozzle, the high-pressure water pipe is prone to shaking during the cleaning process. The operator needs to control the position of the high-pressure water pipe with force, resulting in high labor intensity for the operator. Utility Model Content

[0028] Please also read Figure 1 and Figure 2Now, the pipeline high-pressure flushing nozzle provided by the utility model is described. The pipeline high-pressure flushing nozzle comprises a water spray pipe 1, a guide pipe 2, a support frame 3 and a support wheel 4. A nozzle 11 for flushing the pipeline is installed at one end of the water spray pipe 1; the guide pipe 2 is sleeved on the outside of the water spray pipe 1, and the water spray pipe 1 is slidably arranged inside the guide pipe 2 along the axial direction of the guide pipe 2 and can rotate inside the guide pipe 2; there are multiple support frames 3, and multiple support frames 3 are arranged around the outside of the guide pipe 2; the support wheel 4 is rotatably arranged on the support frame 3, and the axis of the support wheel 4 is perpendicular to the axis of the water spray pipe 1, and is used to support the inner wall of the pipeline to be flushed.

[0029] Compared with the prior art, the pipeline high-pressure flushing nozzle provided in this embodiment is provided with a guide tube 2, and the water spray pipe 1 is slidably arranged inside the guide tube 2 and can rotate relative to the guide tube 2. A plurality of support frames 3 are installed on the outside of the guide tube 2, and the plurality of support frames 3 are evenly spaced along the circumference of the guide tube 2. A support wheel 4 is rotatably arranged on the outside of the support frame 3. When the guide tube 2 moves into the inside of the pipeline, the support wheel 4 is rolled and arranged on the inner wall of the pipeline. When in use, the operator can place the guide tube 2 and the water spray pipe 1 together into the pipeline, and transport high-pressure water to the nozzle 11 through the water spray pipe 1, and spray it to the inner wall of the pipeline to clear the scale on the inner wall of the pipeline. At the same time, through the setting of the guide tube 2 and the support wheel 4 on the support frame 3, it is used to abut against the inner wall of the pipeline. While being able to play a certain supporting role on the water spray pipe 1, it is convenient to push the guide tube 2 into the pipeline to be cleaned. When in use, the operator realizes the operation of removing the scale on the inner wall of the pipeline by rotating the water spray pipe 1 or pushing the water spray pipe 1. The operation process is simple and easy to use, which reduces the labor intensity of the operator.

[0030] Specifically, in this embodiment, the axis of the rotating shaft of the support wheel 4 and the axis of the guide tube 2 are arranged perpendicular to each other.

[0031] In some embodiments, the support frame 3 may be Figure 1 , Figure 2 See also Figure 1 , Figure 2The support frame 3 includes a swing rod 31, a sliding sleeve 33, a support rod 32 and a pushing assembly 5. One end of the swing rod 31 is hinged on the guide tube 2, and the support wheel 4 is rotatably set at the other end of the swing rod 31; the sliding sleeve 33 is slidably set on the outside of the guide tube 2 along the axial direction of the guide tube 2; one end of the support rod 32 is hinged on the outside of the sliding sleeve 33, and the other end is hinged on the middle of the swing rod 31; the pushing assembly 5 is set between the sliding sleeve 33 and the guide tube 2, and is used to push the sliding sleeve 33 to move in the direction close to the hinge axis of the swing rod 31 on the guide tube 2. A fixed sleeve is fixedly installed on the outside of the guide tube 2, one end of the swing rod 31 is hinged on the fixed sleeve, and the hinge axis of the swing rod 31 and the axis of the guide tube 2 are perpendicular to each other. The support wheel 4 is rotatably set at the other end of the swing rod 31, and the distance between the support wheel 4 and the guide tube 2 can be changed by the swing of the swing rod 31. Therefore, it can be suitable for cleaning pipes of different sizes.

[0032] Specifically, in this embodiment, the support rods 32 on the multiple swing rods 31 are hingedly arranged on the sliding sleeve 33. The multiple swing rods 31 can be driven to swing simultaneously by pushing the sliding sleeve 33 to move, so that the multiple support wheels 4 move outward or inward synchronously, and the water spray pipe 1 is always located in the center.

[0033] In some embodiments, the pushing component 5 can be used as follows: Figure 1 , Figure 2 See also Figure 1 , Figure 2 The pushing assembly 5 includes a limiting sleeve 51 and an elastic member 52. The limiting sleeve 51 is installed on the guide tube 2; one end of the elastic member 52 abuts against the limiting sleeve 51 and the other end abuts against the sliding sleeve 33. The limiting sleeve 51 is installed on the outer side of the guide tube 2, and the two ends of the elastic member 52 abut against the limiting sleeve 51 and the sliding sleeve 33 respectively. Through the setting of the elastic member 52, a force can be given to the sliding sleeve 33 to always keep moving away from the limiting sleeve 51. Thereby, the support wheel 4 can be supported on the inner wall of the pipe. At the same time, when the guide tube 2 moves to the inside of the pipe to be cleaned, the support of the support wheel 4 by the inner wall of the pipe can drive the swing rod 31 to swing, and the guide tube 2 can be moved to the inside of the pipe to be cleaned without adjustment.

[0034] Specifically, in this embodiment, the elastic member 52 is a spring.

[0035] In some embodiments, the above-mentioned limit sleeve 51 can be used as follows Figure 1 , Figure 2 See also Figure 1 , Figure 2The limiting sleeve 51 is sleeved on the outer side of the guide tube 2, and the outer side of the guide tube 2 is threadedly connected to the limiting member 53, and the limiting member 53 is located at the end of the limiting sleeve 51 away from the elastic member 52. The limiting sleeve 51 is installed on the outer side of the guide tube 2 and is slidably arranged on the guide tube 2. The limiting member 53 is threadedly connected to the outer wall of the guide tube 2, and the limiting member 53 is a bolt, which can limit the limiting sleeve 51 to move in a direction away from the sliding sleeve 33. At the same time, by removing the limiting member 53, the removal and installation of the limiting sleeve 51 can be facilitated.

[0036] Preferably, in this embodiment, a plurality of threaded holes for installing the stopper 53 are provided on the outer wall of the guide tube 2, and the plurality of threaded holes are sequentially spaced apart along the axial direction of the guide tube 2. The tension of the swing rod 31 can be adjusted.

[0037] In some embodiments, the above-mentioned stopper 53 can be adopted as follows Figure 1 , Figure 2 See also Figure 1 , Figure 2 The number of the limiting members 53 is multiple, and the multiple limiting members 53 are evenly arranged around the outside of the guide tube 2. The multiple limiting members 53 are evenly arranged on the outside of the guide tube 2 along the circumference of the guide tube 2, which can provide stable support for the limiting sleeve 51, thereby ensuring the stability of the installation of the limiting sleeve 51.

[0038] In some embodiments, the above-mentioned limit sleeve 51 can be used as follows Figure 1 , Figure 2 See also Figure 1 , Figure 2 The end of the limiting sleeve 51 is concavely provided with a slot for accommodating the limiting member 53. A plurality of slots are provided at the end of the limiting sleeve 51. When the limiting member 53 is installed on the guide tube 2, the middle of the limiting member 53 is located inside the slot. This can prevent the limiting sleeve 51 from rotating itself, thereby improving the stability of the installation of the limiting sleeve 51.

[0039] In some embodiments, the swing bar 31 may be Figure 1 , Figure 2 See also Figure 1 , Figure 2 The middle part of the swing rod 31 is also provided with a guide wheel 6 for guiding the swing rod 31 to swing close to the guide tube 2. The middle part of the swing rod 31 is provided with a guide wheel 6, and the number of the guide wheel 6 is at least one. When the number of the guide wheels 6 is multiple, the multiple guide wheels 6 are sequentially arranged at intervals along the length direction of the swing rod 31. Through the arrangement of the guide wheel 6, when the guide tube 2 is initially placed inside the pipeline to be cleaned, the guide wheel 6 can preferentially contact the inner wall of the pipeline to be cleaned. And the swing rod 31 is swung to the retracted state by the guidance of the guide wheel 6, and finally the support wheel 4 is supported on the inner wall of the pipeline.

[0040] In some embodiments, the water spray pipe 1 can be used as follows Figure 1 , Figure 2 See also Figure 1 , Figure 2 A plurality of nozzles 11 are installed at the end of the water spray pipe 1, and the spray direction of the nozzles 11 is tilted outward in a direction away from the water spray pipe 1. The plurality of nozzles 11 are evenly spaced along the circumference of the water spray pipe 1. The spray direction of the nozzles 11 is set at an angle to the axis of the water spray pipe 1. After the nozzles 11 clean the scale on the inner wall of the pipe, they can also push the cleaned structure to move backward, thereby removing the scale inside the pipe and reducing the subsequent cleaning operations.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
