DETAILED DESCRIPTION
[0029] The following is combined with Figure 1-3 This application is described in further detail.
[0030] The present application embodiment discloses an arc-shaped heating hood for an electrolyte diaphragm, referring to Figure 1 , Figure 2 and Figure 3 , installed on both sides of the forming steel roller, including a first heating air hood 1 and a second heating air hood 2 installed oppositely, the first heating air hood 1 including an air outlet surface 3, the air outlet surface 3 is arranged in an inwardly concave arc shape, an air outlet 31 is opened in the first heating air hood 1, an air inlet 32 is opened on the side of the first heating air hood 1 away from the air outlet surface 3, a first vacuum pump 33 is installed on the air inlet 32, and the first heating air hood 1 is arranged together with the second heating air hood 2, a heating net 34 is installed on the air outlet 31, a protective net 6 is installed on the side of the heating net 34 away from the air outlet 31, the protective net 6 and the heating net 34 are arranged at intervals, and recovery structures 4 are installed on both sides of the first heating air hood 1.
[0031] The first vacuum pump 33 pumps the air at the air inlet 32 to the air outlet 31, and then the heating net 34 heats the air, thereby heating and drying the electrolyte membrane. The air outlet surface 3 is set in an inwardly concave arc, which can make the air outlet 31 better fit the side wall of the formed steel roller, thereby better heating and drying the electrolyte membrane on the formed steel roller. The recovery structure 4 can recycle and reuse part of the hot air that has been used to heat and dry the electrolyte membrane, thereby reducing the heat required for heating the air and reducing energy consumption. The protective net 6 can prevent burns caused by direct contact between the operator and the heating net 34.
[0032] The hot air used to heat and dry the electrolyte membrane will carry some heat, and it is wasteful to discharge it directly. In order to improve the efficiency of heat utilization, refer to Figure 1 , Figure 2 and Figure 3In this embodiment, the fixed recovery structure 4 includes a left air inlet 41, a right air inlet 42, an exhaust pipe 43, an exhaust pipe 44 and a second exhaust pump 45. The left air inlet 41 and the right air inlet 42 are respectively opened on both sides of the first heating air hood 1. One end of the exhaust pipe 43 is connected to the left air inlet 41 and the right air inlet 42 respectively, and the other end of the exhaust pipe 43 is connected to the air inlet of the second exhaust pump 45. The exhaust pipe 44 is arranged on the air outlet of the exhaust pipe 43, and one end of the exhaust pipe 44 away from the second exhaust pump 45 is connected to the air inlet 32. The second exhaust pump 45 can extract part of the hot air that has heated the electrolyte membrane through the left air inlet 41, the right air inlet 42 and the exhaust pipe 43, and then transport it to the air inlet 32 through the exhaust pipe 44, so as to realize the reuse of the hot air and reduce the waste of heat.
[0033] The distance between the first heating hood 1, the second heating hood 2 and the forming steel roller will also affect the heating and drying effect of the electrolyte membrane. Figure 1 , Figure 2 and Figure 3 Therefore, in this embodiment, two first guide rails 11 are installed below the first heating hood 1 by bolts, and the first heating hood 1 is slidably installed on the two first guide rails 11, and two second guide rails 21 are installed below the second heating hood 2 by bolts, and the second heating hood 2 is slidably installed on the two second guide rails 21. The first heating hood 1 is slidably set on the first guide rail 11, and the second heating hood 2 is slidably set on the second guide rail 21, so that the first heating hood 1 and the second heating hood 2 can be moved closer to or farther from each other, so as to adjust the distance to the most suitable position for heating and drying the electrolyte diaphragm on the forming steel roller, thereby improving the heating and drying effect of the electrolyte diaphragm.
[0034] Manually pushing the first heating hood 1 and the second heating hood 2 to adjust the distance between the first heating hood 1 and the second heating hood 2 is troublesome and laborious. Figure 1 , Figure 2 and Figure 3Therefore, in this embodiment, the fixed driving component 5 includes a gear 51, a rotating rod 52, two sliding blocks 53 and a driving motor 54. A rack is welded and installed on the first guide rail 11. Sliding grooves 55 are provided on the two sliding blocks 53. The two sliding blocks 53 are slidably installed on the two first guide rails 11 through the sliding grooves 55. The two ends of the rotating rod 52 are rotatably installed on the two sliding blocks 53 respectively. The driving motor 54 is fixedly installed on the sliding blocks 53, and the output shaft is connected to the rotating rod 52. The gear 51 is coaxially arranged on the rotating rod 52, and the rack is meshed with the gear 51. Limiting plates 56 are arranged at both ends of the sliding groove 55. The driving motor 54 drives the rotating rod 52 to rotate. Since the gear 51 and the rack are meshed, and the sliding block 53 is slidably installed on the first guide rail 11, when the rotating rod 52 rotates, the gear 51 moves on the rack, driving the sliding block 53 to move on the first guide rail 11, thereby adjusting the position of the first heating air hood 1 or the second heating air hood 2. The limit plate 56 can prevent derailment between the gear 51 and the rack.
[0035] The implementation principle of an arc-shaped heating hood for an electrolyte diaphragm in the embodiment of the present application is as follows:
[0036] Start the first vacuum pump 33, which can pump the air at the air inlet 32 to the air outlet 31, and then the heating network 34 heats the air, so as to heat and dry the electrolyte membrane. The concave arc shape of the air outlet surface 3 can make the air outlet 31 better fit the side wall of the formed steel roller, so as to better heat and dry the electrolyte membrane on the formed steel roller.
[0037] The second air pump 45 is started. The second air pump 45 can extract part of the hot air that has heated the electrolyte membrane through the left air inlet 41, the right air inlet 42 and the air extraction pipe 43, and then transport it to the air inlet 32 through the air outlet pipe 44, thereby realizing the reuse of the hot air and reducing the waste of heat.
[0038] When it is necessary to adjust the distance between the first heating hood 1 and the second heating hood 2, start the driving motor 54, and the driving motor 54 drives the rotating rod 52 to rotate. Since the gear 51 and the rack are meshed, and the sliding block 53 is set in the sliding groove 55, when the rotating rod 52 rotates, the gear 51 can be moved on the rack, thereby adjusting the position of the first heating hood 1 or the second heating hood 2.
