Technical Field

[0001] The utility model relates to the technical field of steam pipeline construction, in particular to a steam pipeline construction protective device. Background Art

[0002] Steam pipes are special piping systems used to transport steam in industrial and civil facilities. They mainly carry high-temperature and high-pressure steam generated by steam boilers for various purposes, such as heating, power generation, industrial processing, food disinfection, etc. Steam pipes are widely used in power plants, chemical plants, refineries, paper mills, heating systems and various industrial production processes.

[0003] When high-temperature steam is transported in a steam pipeline, some impurities will be contained in the steam. Since the impurities are corrosive to a certain extent, when the impurities are accumulated on the filter plate in the steam pipeline, the steam pipeline will be blocked and the steam pipeline opening will be corroded, which will affect the filtering efficiency of the filter frame. When workers are maintaining the steam pipeline opening corroded by impurities, there is a high possibility that the pipeline will rupture, posing a threat to the personal safety of construction workers.

[0004] Therefore, it is urgent to propose a steam pipeline construction protection device that can clean impurities and avoid corrosion. Utility Model Content

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] Embodiment: A steam pipeline construction protection device, such as Figure 1-Figure 6 As shown, it includes a mounting cover 1, a pipeline 2, a filter frame 3, a filter screen 31, a connecting rod 4, a pull rod 5, a scraper rod 6 and a magnet Ⅰ7. The mounting cover 1 is provided with connecting ports on the front and rear sides, and the connecting ports of the mounting cover 1 are connected to the pipeline 2. The mounting cover 1 is provided with a filter frame 3 movably arranged inside the mounting cover 1, and the filter frame 3 can be pulled out and pushed in from the mounting cover 1. The filter screen 31 is arranged on the front and rear sides of the filter frame 3. The apertures of the filter screens 31 on the front and rear sides are dense and loose respectively. The top of the mounting cover 1 is provided with connecting rods 4 in a sliding manner on both sides, and the bottom of the connecting rods 4 is symmetrically provided with pull rods 5 in a front-to-back manner. Scraper rods 6 are arranged between the connecting rods 4 on the front and rear sides. The scraper rods 6 are in sliding contact with the filter screen 31. When the scraper rods 6 move up and down, they will contact with the filter screen 31 and clean the impurities on the filter screen 31. The top of the scraper rods 6 is symmetrically provided with magnets Ⅰ7.

[0026] like Figure 2 and Figure 6-Figure 7 As shown, it includes a guide rod 8, a scraper ring 9, a winding wheel 10, a pull rope 101, a spring 11 and a magnet II 12. Guide rods 8 are arranged on both sides of the inner side of the middle of the pipe 2. A scraper ring 9 is arranged between the guide rods 8, and the scraper ring 9 is in sliding contact with the inner wall of the pipe 2. Winding wheels 10 are installed on the inner side of the bottom of the left and right guide rods 8. A pull rope 101 is wound in the winding wheel 10. The pull rope 101 is initially in a straight state as a whole, and the outward end of the pull rope 101 is connected to the scraper ring 9. The guide rods 8 are arranged on the inner side of the bottom of the left and right guide rods 8. A spring 11 is arranged between the rod 8 and the scraper ring 9, and a magnet II 12 is arranged on the inward end of the pull rope 101. The bottom of the magnet II 12 contacts the inward end of the guide rod 8, and the magnet I7 cooperates with the magnet II 12 by magnetic attraction. When the scraper rod 6 drives the magnet I7 and the magnet II 12 in an attractive state to move upward, the magnet II 12 will pull the pull rope 101 wound on the winding wheel 10, so that the pull rope 101 will pull the scraper ring 9 to move inward along the guide rod 8 and scrape off the impurities on the inner wall of the pipe 2.

[0027] like Figure 1-Figure 3As shown, a collecting frame 13 is also included. The collecting frames 13 are fixedly arranged on the left and right sides of the bottom of the filter frame 3. The collecting frame 13 is located at the bottom of the scraper rod 6. The collecting frame 13 is a shell for collecting impurities in the pipeline 2.

[0028] like Figure 1-Figure 2 and Figure 6 As shown, a flow partition 14 is also included. The flow partition 14 is fixedly arranged on the front side of the inner side of the pipeline 2, and the flow partition 14 is a semicircular cover.

[0029] like Figure 1-Figure 2 and Figure 6 As shown, an adjusting plate 15 is also included. The adjusting plate 15 is rotatably arranged on the outer side of the flow partition 14. The adjusting plate 15 is a semicircular cover body, and the cylindrical cover body formed when the adjusting plate 15 and the flow partition 14 cooperate can close the port of the pipeline 2. When the flow rate of the steam transported in the pipeline 2 needs to be adjusted, the outlet size of the pipeline 2 can be adjusted by rotating the adjusting plate 15. Through holes are symmetrically opened on the inner sides of the flow partition 14 and the adjusting plate 15, and the through holes are flow holes that separate the flow rate of steam transport.

[0030] like Figure 1 As shown, an insulation plate 16 is also included. The top of the pipeline 2 is provided with an insulation plate 16. When the pipeline 2 is transporting steam, the pipeline 2 can be insulated to reduce heat energy loss, prevent condensation water from forming, and damage the pipeline 2 system.

[0031] When the steam pipe 2 is protected and cleaned, the connecting rod 4 is first pulled upward, and the connecting rod 4 will drive the pull rod 5 and the scraper rod 6 to move. When the scraper rod 6 moves upward, the impurities on the filter screen 31 will be scraped off, and the impurities will fall into the filter frame 3. In the process of the connecting rod 4 being pulled, the magnet I7 on the scraper rod 6 will move upward at the same time. When the magnet I7 moves to the same height as the magnet II12, the magnet I7 and the magnet II12 will be magnetically matched, and the magnet I7 and the magnet II12 will attract each other. The scraper rod 6 drives the magnet I7 and the magnet II12 to move upward synchronously. When the magnet II12 moves upward, the rope 101 wound on the winding wheel 10 is pulled synchronously, so that the rope 101 pulls the scraper ring 9, and the scraper ring moves inward along the guide rod 8 and scrapes the impurities on the inner wall of the pipe 2. As the scraper ring 9 moves inward, it squeezes the spring 11, causing the spring 11 to deform and form a compressed state. When the scraper ring 9 moves inward, the impurities scraped away will eventually fall. In the collecting frames 13 on both sides of the filter frame 3, the collecting frames 13 will collect impurities in a centralized manner. After the filter screen 31 and the inner wall of the pipe 2 are cleaned, the impurities in the filter frame 3 and the collecting frames 13 need to be cleared. At this time, the connecting rod 4 is pushed downward so that each component is driven to move downward and reset. In the process of the connecting rod 4 being pushed downward, the pull rope 101 is in a state of being stretched without force, so that the spring 11 is not squeezed by the scraper ring 9 and resets to form a stretched state. When the spring 11 is stretched, the scraper ring 9 will be pushed and reset by it. When the components are reset, the filter frame 3 can be pulled out of the mounting cover 1, and the collecting frames 13 arranged on both sides of the mounting cover 1 are also pulled out at the same time. Then the filter frame 3 and the collecting frame 13 can be rinsed to thoroughly clean the impurities. When the pipe 2 is transporting steam, the exhaust gas emission flow rate can be adjusted by rotating the adjusting plate 15. The temperature generated in the pipe 2 during emission can be maintained by the insulation plate 16 to achieve the protection of the steam pipe 2.

[0032] The above-mentioned embodiments only express the preferred implementation of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
