Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of industrial compensators, and in particular to a water-cooled compensator. Background Technology
[0002] In blast furnace blast systems, bellows compensators play a crucial role in absorbing displacement, relieving stress, and ensuring the safe and reliable operation of the system. Because the compensator operates in a high-temperature environment, although it has an internal lining filled with fiberglass, high temperatures can still be transmitted to the outer surface of the bellows, thus affecting its quality. Utility Model Content
[0003] In order to solve the problems existing in the prior art, the present invention provides a water-cooled compensator.
[0004] The water-cooled compensator provided by this utility model adopts the following technical solution:
[0005] A water-cooled compensator includes an upper flange and a lower flange, which are fixed together by connecting bolts and nuts. An upper fixing ring is fixed to the bottom surface of the upper flange, and a lower fixing ring is fixed to the top surface of the lower flange. A bellows is connected between the upper and lower fixing rings. An inner liner plate 1 is fixed to the bottom surface of the upper flange, and a fire-resistant layer is provided on the inner side of the inner liner plate 1. An inner liner plate 2 and an inner liner plate 3 are fixed to the top surface of the lower flange. A closing ring is fixed to the top of the inner liner plate 2 and the inner liner plate 3. Ceramic fiber is filled between the inner liner plate 2 and the bellows, and between the closing ring and the upper flange. An inlet pipe and an outlet pipe are horizontally fixed to the inner liner plate 2. The inlet pipe and the outlet pipe are connected to the water flow channel formed between the inner liner plate 2 and the inner liner plate 3. The inlet pipe and the outlet pipe pass through the lower fixing ring and are fixed to the lower fixing ring.
[0006] By adopting the above technical solution, cooling water enters the water flow channel formed between inner lining plate two and inner lining plate three through the water inlet pipe. After passing through the wave-shaped water flow channel, the cooling water is discharged through the water outlet pipe. In this process, the cooling water absorbs and carries away some heat, which has the effect of cooling inner lining plate two, thereby reducing the surface temperature of the corrugated pipe and ensuring the quality of the corrugated pipe.
[0007] Preferably, multiple guide strips are uniformly and vertically fixed between the inner lining plate two and the inner lining plate three along the circumference, with adjacent guide strips arranged alternately up and down, and the water flow channel arranged in a wave shape.
[0008] By adopting the above technical solution, the cooling water fully absorbs heat and cools the inner lining plate 2 and inner lining plate 3.
[0009] Preferably, the inlet pipe and / or outlet pipe are vertically connected to the ends of the pipes, and the top of the vertical pipes are horizontally connected to the transverse pipes in the direction away from the corrugated pipes. The ends of the transverse pipes are detachably connected to the water supply pipes used for water supply via a joint.
[0010] By adopting the above technical solution, setting up vertical and horizontal extension pipes facilitates the formation of an operating area and makes it easier for staff to connect water supply pipes.
[0011] Preferably, an L-shaped bracket is fixed to the top surface of the lower flange. The bracket includes a vertical part fixed to the inlet pipe or outlet pipe and a horizontal part fixed to the vertical extension pipe.
[0012] By adopting the above technical solution, the bracket effectively fixes the vertical and horizontal extension tubes.
[0013] Preferably, a guide tube is fitted on the outside of the water supply pipe. The guide tube is flared, with the end of the guide tube facing away from the corrugated pipe being the larger end. A bracket is fixedly connected between the guide tube and the lower flange.
[0014] By adopting the above technical solution, the guide tube not only protects the water supply pipe, but also prevents the water supply pipe from being accidentally bent, thus ensuring the smooth flow of water.
[0015] Preferably, the guide tube has a threaded screw for fixing the water pipe.
[0016] By adopting the above technical solution, the set screw positions the water pipe, further improving the stability of the water supply and drainage process. Attached Figure Description

[0021] The following combination Figures 1-3 The present invention will be further described in detail below. An embodiment of the present invention discloses a water-cooled compensator. Example 1
[0022] Reference Figure 1 The water-cooled compensator includes an upper flange 1 and a lower flange 2. Multiple connecting bolts 3 are evenly installed around the axis between the upper flange 1 and the lower flange 2. The connecting bolts 3 are fixed by connecting nuts 4. An upper fixing ring 5 is fixed to the bottom surface of the upper flange 1, and a lower fixing ring 6 is fixed to the top surface of the lower flange 2. A bellows 7 is fixed between the inner side of the upper fixing ring 5 and the inner side of the lower fixing ring 6. An inner liner plate 8 is vertically fixed to the central through hole of the upper flange 1. The inner liner plate 8 is tubular and passes through the central through hole of the lower flange 2. The diameter of the central through hole of the lower flange 2 is larger than the diameter of the central through hole of the upper flange 1.
[0023] Reference Figure 1 A fire-resistant layer 9 is fixed inside the inner side of the inner lining plate 8. A boss 200 protruding in the direction of the inner axis is provided at the inner edge of the lower flange 2. A tubular inner lining plate 10 is fixed to the edge of the top surface of the lower flange 2 near the boss 200. A tubular inner lining plate 11 is fixed to the edge of the top surface of the boss 200 near the central through hole of the lower flange 2. A sealing ring 12 is fixed between the top ends of the inner lining plate 10 and the inner lining plate 11, forming a water flow channel between the inner lining plate 10 and the inner lining plate 11.
[0024] Reference Figure 1 and Figure 2 Ceramic fibers 13 are filled between the bottom surface of the upper flange 1 and the top surface of the sealing ring 12. Ceramic fibers 13 are also filled between the corrugated pipe 7 and the inner lining plate 2 10. An inlet pipe 14 and an outlet pipe 15 are horizontally fixed to the inner lining plate 2 10. The inlet pipe 14 and the outlet pipe 15 are respectively connected to the water flow channel. The inlet pipe 14 and the outlet pipe 15 are respectively passed through the lower fixed ring 6 and fixed to the lower fixed ring 6. Multiple guide strips 16 are evenly vertically fixed between the inner lining plate 2 10 and the inner lining plate 3 11 along the circumference. Two adjacent guide strips 16 are arranged alternately up and down, so that the water flow channel is arranged in a wave shape.
[0025] The implementation principle of Embodiment 1 of this utility model is as follows: Cooling water enters the water flow channel formed between the inner lining plate 2 10 and the inner lining plate 3 11 through the water inlet pipe 14. After passing through the wave-shaped water flow channel, the cooling water is discharged through the water outlet pipe 15. During this process, the cooling water absorbs and carries away some heat, which has the effect of cooling the inner lining plate 2 10, thereby reducing the surface temperature of the corrugated pipe 7 and ensuring the quality of the corrugated pipe 7. Example 2
[0026] Reference Figure 3The difference between this embodiment and embodiment 1 is that, in this embodiment, the ends of the inlet pipe 14 and the outlet pipe 15 are also vertically connected to a vertical extension pipe 17. Taking the vertical extension pipe 17 located on the inlet pipe 14 as an example, the top of the vertical extension pipe 17 is horizontally connected to a horizontal extension pipe 18 in the direction away from the corrugated pipe 7. The horizontal extension pipe 18 is connected to the water supply pipe 19 for transporting cooling water through a connector 20 installed at the end of the water supply pipe 19.
[0027] Reference Figure 3 A bracket 21 is fixedly connected to the top surface of the lower flange 2. The bracket 21 is L-shaped and includes a vertical part fixed to the water inlet pipe 14 and a horizontal part fixed to the vertical extension pipe 17. A funnel-shaped guide tube 22 is sleeved on the outside of the water supply pipe 19. The end of the guide tube 22 away from the corrugated pipe 7 is the large end. A bracket 23 is fixed between the guide tube 22 and the lower flange 2. A set screw 24 for tightening and fixing the water supply pipe 19 is also threaded on the wall of the guide tube 22.
[0028] The implementation principle of Embodiment 2 of this utility model is as follows: the water inlet pipe 14 and the water outlet pipe 15 are extended by the vertical extension pipe 17 and the horizontal extension pipe 18 to provide space for easy operation by the staff. The water supply pipe 19 can be detachably installed on the horizontal extension pipe 18 through the connector 20, for example by using a threaded connection. The water supply pipe 19 is inserted into the guide tube 22. The guide tube 22 not only protects the water supply pipe 19, but also prevents the water supply pipe 19 from being accidentally bent, so as to ensure the smoothness of water supply. The set screw 24 positions the water supply pipe 19, further improving the stability of the water supply pipe 19 in the process of water supply and drainage.
[0029] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
