Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figures 1-4 The present invention provides a prefabricated elbow structure for a heat-insulating pipe, including a fixing plate 1, an elbow body 3 at the bottom of the fixing plate 1, a support block 2 connected to the fixing plate 1 at the bottom of the elbow body 3, a filter cleaning mechanism on the side of the elbow body 3 near the inlet section, and a collection mechanism on the side of the elbow body 3 near the filter cleaning mechanism.
[0026] The elbow body 3 is supported and fixed by bolts to the fixing plate 1 and the support block 2. During the use of the elbow body 3, the filter cleaning mechanism is used to filter the impurities generated during the use of the elbow body 3. Then, the collection mechanism is used to collect the filtered impurities, making it more convenient for operators to clean and collect the impurities and improving the practicality of the equipment.
[0027] The filtration and cleaning mechanism includes a sleeve 5 fixedly connected to the outer contour of the elbow body 3. A rotating shaft 6 rotatably connects through the inner wall of the sleeve 5. An equipment box 7 is fixedly connected to the inner wall of the elbow body 3. One end of the rotating shaft 6 passes through and rotatably connects to the equipment box 7. A filter plate 8 is provided on the inner wall of the elbow body 3 near the equipment box 7. A connecting shaft 9 rotatably connects to the equipment box 7 passes through the middle of the filter plate 8. An L-shaped cleaning plate 10 is fixedly connected to the end of the connecting shaft 9 near the filter plate 8. The filtration and cleaning mechanism also includes a cleaning plate 10 disposed on the rotating shaft 6 near the equipment box 7. The bevel gear 4 on the wall, and the bevel gear 20 on the connecting shaft 9 near the inner wall of the equipment box 7, which meshes with the bevel gear 4, are provided. A sealing knob 15 is detachably connected to the side of the sleeve 5 away from the elbow body 3. A threaded ring 17 is fixedly connected to the side of the sealing knob 15 near the sleeve 5. A threaded groove 18 is opened on the sleeve 5 for the threaded ring 17 to be screwed in. A sealing rubber ring 19 is fitted on the outer contour of the threaded groove 18. A rotating block 16 is fixedly connected to the end of the rotating shaft 6 near the sealing knob 15. A groove is opened on the sealing knob 15 to match the rotating block 16.
[0028] During use, the filter plate 8 filters impurities generated within the elbow body 3. When the filtered impurities need to be processed, the operator first rotates the sealing knob 15 to rotate the threaded ring 17. Because the inner wall of the threaded ring 17 near the sealing ring 19 has a sealing groove that matches the sealing ring 19, the threaded ring 17 is removed from the threaded groove 18, and the sealing ring 19 fitted on the threaded ring 17 is also removed from the sealing groove. At this time, the operator rotates the rotating block 16 to rotate the rotating shaft 6. The rotating shaft 6 drives the bevel gear 4 to rotate, which in turn drives the bevel gear 20 meshing with it to rotate. This, in turn, drives the connecting shaft 9 to rotate. The L-shaped cleaning plate 10, which is positioned on the side, is rotated by the rotating connecting shaft 9. The L-shaped cleaning plate 10 cleans the impurities generated on the surface of the filter plate 8 and lifts the impurities at the distance between the filter plate 8 and the discharge pipe 11 upwards by rotation. Then, the impurities fall into the discharge pipe 11 by gravity, thus collecting the impurities.
[0029] The collection mechanism includes a discharge pipe 11 fixedly connected to the inner wall of the elbow body 3 near the filter plate 8. A collection box 12 is provided at the bottom of the discharge pipe 11. Flanges 13 are provided on the outer contours of the opposite sides of the discharge pipe 11 and the collection box 12 and are connected by the flanges 13. An inner cylinder 14 is snapped into the inner wall of the flange 13. Filter holes are opened at the bottom of the inner cylinder 14.
[0030] By removing the bolts on the flange 13, the collection box 12 is disassembled, and then the inner cylinder 14 is removed from the collection box 12. The impurities and the liquid in the impurities are separated by the inner cylinder 14 and the filter holes at its bottom. Then the impurities are cleaned.
[0031] Working principle: During the use of the elbow body 3, the filter plate 8 filters out impurities generated inside the elbow body 3. When it is necessary to process the filtered impurities, the operator first rotates the sealing knob 15 to rotate the threaded ring 17. Because the inner wall of the threaded ring 17 near the sealing ring 19 has a sealing groove that matches the sealing ring 19, the threaded ring 17 is removed from the threaded groove 18, and the sealing ring 19 fitted on the threaded ring 17 is also removed from the sealing groove. At this time, the operator rotates the rotating block 16 to rotate the rotating shaft 6, which in turn rotates the bevel gear 4. The bevel gear 4 then drives the bevel gear 20 that meshes with it to rotate. The rotating shaft 9 is driven to rotate by the bevel gear 20. The L-shaped cleaning plate 10 is rotated by the rotating connecting shaft 9. The L-shaped cleaning plate 10 cleans the impurities generated on the surface of the filter plate 8. The impurities at the distance between the filter plate 8 and the discharge pipe 11 are lifted upward by the rotation and then fall into the discharge pipe 11 by gravity. The impurities can be collected by removing the bolts on the flange 13 and then removing the collection box 12. The inner cylinder 14 is then taken out of the collection box 12. The impurities and the liquid in the impurities are separated by the inner cylinder 14 and the filter holes at its bottom. The impurities are then cleaned.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
