Description

Technical Field

[0001] This utility model belongs to the technical field of valve opening observation tools, and in particular relates to a quick observation device for disassembling dust removal pipeline valves. Background Technology

[0002] The steel plant currently has 27 sets of dust removal equipment and 412 dust removal valves. Some of the electric dust removal valves can only display "open" and "closed," but the actual opening degree is unknown. During the dust control process, it is often encountered that the dust removal fan has a high Hertz, the dust removal pipeline has no dust accumulation, and the air volume is large, but the on-site dust removal effect is poor. Only after maintenance personnel cut open the dust removal pipeline to check the opening degree of the dust removal valves did they find that some dust removal valves, which indicated that they were fully open, were only open to about 70% on-site, causing insufficient airflow and poor on-site dust removal effect. Each inspection requires maintenance personnel to cut open the dust removal pipeline, and after inspection, they have to weld it back on, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0003] The purpose of this invention is to provide a quick observation device for disassembling valves in dust removal pipelines, in order to solve the problems existing in the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A quick observation device for disassembling valves in a dust removal pipeline includes a dust removal pipe with a dust removal valve installed on it. Two fixed pipes are connected to the dust removal pipe, and a rotating pipe is inserted into the fixed pipe. A cover is threaded to the bottom of the rotating pipe, and a sight glass is pressed between the rotating pipe and the cover. Grooves are formed on the inner walls of both sides of the fixed pipe, and an L-rod is inserted into each of the two grooves. A scraper is fixed to the bottom of the two L-rods.

[0006] Furthermore, the fixed pipe is in the shape of a round tube, with a flange welded to the top and a retaining ring welded to the bottom. The groove extends from the inner wall of the fixed pipe to the retaining ring. The bottom of the fixed pipe passes through and is fixed obliquely to the dust removal pipe, with the bottom of the fixed pipe facing the dust removal valve.

[0007] Furthermore, the rotating tube is cylindrical, and an external threaded tube is connected to the bottom end of the rotating tube. The outer wall of the external threaded tube is threaded.

[0008] Furthermore, the cover is in the shape of a cylindrical tube, the inner wall of the cover is internally threaded, the cover is connected to the rotating tube through an external thread, and a retaining ring is connected to the bottom of the cover.

[0009] Furthermore, the sight glass is located on the retaining ring of the cover, and the rotating tube presses the sight glass onto the cover through the external thread tube.

[0010] Furthermore, the scraper is a brush or a flexible rubber plate, and the scraper abuts against the bottom of the sight glass.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model has a simple structure and is easy to operate. It can be disassembled and installed, so as to quickly observe the opening degree of the dust removal valve in the dust removal pipe.

[0013] 2. Observation can be carried out through the sight glass without cutting the dust collection pipe, which greatly saves maintenance workload, reduces labor intensity, and avoids delaying production.

[0014] 3. When not in use, the rotating tube can be pulled out to prevent the sight glass from being scratched by dust accumulation and friction inside the dust removal tube over a long period of time. A blind flange is used to fasten it to the flange to block the connection between the fixed tube and the outside.

[0015] 4. Rotate the rotating tube to scrape the sight glass through the hanging plate to prevent dust from accumulating and clogging the sight glass during observation, thereby providing a better field of view. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0022] like Figure 1-4 As shown, a quick observation device for valve disassembly of a dust removal pipe includes a dust removal pipe 1, a dust removal valve installed on the dust removal pipe 1, two fixed pipes 3 connected to the dust removal pipe 1, a rotating pipe 4 inserted into the fixed pipe 3, a cover 5 threaded to the bottom end of the rotating pipe 4, a sight glass 6 pressed between the rotating pipe 4 and the cover 5, grooves 7 are opened on the inner walls of both sides of the fixed pipe 3, and L rods 8 are inserted into both grooves 7, and scrapers 9 are fixed to the bottom ends of the two L rods 8.

[0023] The fixed pipe 3 is cylindrical, with a flange 10 welded to its top. The flange 10 is used to fasten a blind flange and to seal the pipe when not in use. A retaining ring 11 is welded to the bottom of the fixed pipe 3, which is used to hold the cover 5 in place. A groove 7 extends from the inner wall of the fixed pipe 3 to the retaining ring 11, and is used to insert the L-rod 8. The bottom of the fixed pipe 3 is fixed to the dust collection pipe 1 at an angle, facilitating observation of the dust collection valve.

[0024] The rotating tube 4 is in the shape of a round tube, and the bottom end of the rotating tube 4 is connected to an external thread tube 12. The outer wall of the external thread tube 12 is threaded, which is used to connect the cover body 5.

[0025] The cover 5 is in the shape of a cylindrical tube, and the inner wall of the cover 5 is internally threaded. The cover 5 is connected to the rotating tube 4 via an external threaded tube 12, which facilitates the replacement of the sight glass 6. A retaining ring 11 is connected to the bottom of the cover 5, and the retaining ring 11 on the cover 5 is used to lock the sight glass 6 in place.

[0026] The sight glass 6 is located on the retaining ring 11 of the cover 5, and the rotating tube 4 presses the sight glass 6 onto the cover 5 through the external thread tube 12.

[0027] The scraper 9 is a brush or a flexible rubber plate. The scraper 9 is in contact with the bottom of the sight glass 6. When the rotating tube 4 rotates, the scraper 9 scrapes the sight glass 6.

[0028] The working principle of this utility model is as follows:

[0029] When in use, place a high-powered flashlight inside a rotating tube 4 to provide light. The operator observes the dust removal valve through another rotating tube 4 and adjusts the opening of the dust removal valve. When the accumulated dust in the dust removal tube 1 adheres to the sight glass 6, rotate the rotating tube 4 and the scraper 9 scrapes the sight glass 6 to remove the accumulated dust and prevent excessive dust from affecting the field of vision.

[0030] After the dust removal valve opening is adjusted, the two rotating pipes 4 are pulled out from the two fixed pipes 3, and the L rod 8 is pulled out from the groove 7. The blind flange is then bolted to the flange 10 to block the connection between the fixed pipe 3 and the outside.

[0031] When the sight glass 6 needs to be replaced, unscrew the cover 5 and replace the sight glass 6. When the scraper bar needs to be replaced, cut the old scraper 9 from the L-bar 8 and re-fix the new scraper 9. If the scraper 9 is a brush, the L-bar 8 can be directly welded to the brush. If the scraper 9 is a rubber plate, the L-bar 8 can be inserted into both ends of the rubber plate to fix it in place.

[0032] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.

[0033] The technologies, shapes, and structures not described in detail in this utility model are all known technologies.
