DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-10 This application is described in further detail.

[0040] Reference Figure 1 and Figure 2 The slurry coating device for PPS composite diaphragm used for hydrogen production by alkaline water electrolysis includes a frame 1, an unwinding rack arranged on the top of one side of the frame 1 for unwinding PPS fabric, and a guide component, a centering component, a slurry coating component and a traction component which are sequentially arranged on the frame 1 in the conveying direction of the PPS fabric; the guide component is used to guide the PPS fabric so as to guide the PPS fabric to the centering component, the centering component is used to center the PPS fabric so that the PPS fabric can face the slurry coating component, the slurry coating component is used to slurry both sides of the PPS fabric, and the traction component pulls the PPS fabric so that the PPS fabric can move along the conveying direction.

[0041] The present application discloses a centering stabilization device for a PPS composite diaphragm used for hydrogen production by alkaline water electrolysis. Figure 1 and Figure 2 The central stabilizing device of the PPS composite diaphragm for alkaline water electrolysis hydrogen production includes a stabilizing component arranged on the frame 1 and located between the coating component and the traction member, and the stabilizing component is used to stabilize the PPS fabric after sizing.

[0042] Reference Figure 2 and Figure 3The unwinding frame includes two connecting arms 2 symmetrically fixed to the top of one side of the frame body 1 and an unwinding drum 21 detachably connected between the two connecting arms 2; PPS fabric is wound on the unwinding drum 21, and a connecting rod 211 coaxially arranged with the unwinding drum 21 is fixedly penetrated on the unwinding drum 21, and a first makeshift opening for making way for the connecting rod 211 is opened on the top of one end of the connecting arm 2 away from the frame body 1, and a first limiting ring 212 is fixedly sleeved on the circumference of the connecting rod 211, and four first limiting rings 212 are provided, and the four first limiting rings 212 are in a group of two. When the connecting rod 211 is extended to the first makeshift opening, the connecting arm 2 is limited between the two first limiting rings 212, and the first makeshift opening on the top surface of the connecting arm 2 is covered with a first cover plate 22, and the top surface of the first cover plate 22 is penetrated by two vertical first bolts 23, which penetrate the first cover plate 22 and are threadedly connected to the connecting arm 2 to fix the first cover plate 22 on the connecting arm 2.

[0043] Reference Figure 3 and Figure 4 The guide assembly includes two adjusting members symmetrically arranged on both sides of the frame 1 and a guide roller 3 arranged between the two adjusting members; the guide roller 3 is used to guide the PPS fabric, and the adjusting member is used to adjust the position of the guide roller 3.

[0044] The adjustment member includes a mounting base 31 longitudinally mounted on the inner side wall of the frame body 1, a first screw 32 rotatably connected to the mounting base 31, a first adjustment block 33 slidably connected to the mounting base 31 and threadedly connected to the first screw 32, and a first guide rod 34 fixedly connected to the mounting base 31. The first guide rod 34 passes through the first adjustment block 33 and is slidably connected to the first adjustment block 33. The length of the first screw 32 is consistent with the length of the mounting base 31. The first screw 32 and the first guide rod 34 are arranged parallel to each other. Two first guide rods 34 are provided in the same mounting base 31, and the first screw 32 is located between the two first guide rods 34. The central axis at the end of the guide roller 3 is rotatably connected to the corresponding first adjustment block 33. In order to facilitate the rotation of the first screw 32, the end of the first screw 32 extends to the outside of the mounting seat 31 and is fixedly connected to the first handle; thereby, the two first handles are rotated in the same direction at the same time, so that the two first adjustment blocks 33 move in the same direction at the same time, thereby driving the guide roller 3 to move toward or away from the unwinding drum 21, thereby adjusting the position of the guide roller 3.

[0045] Reference Figure 4 and Figure 5The centering component includes a first rotating roller 4 rotatably connected between the two inner walls of the frame 1, two groups of pushing components symmetrically arranged on the two inner walls of the frame 1, and a first adjusting roller 41 arranged between the two groups of pushing components; the first rotating roller 4 and the first adjusting roller 41 are located on the same horizontal plane and are parallel to each other, and the pushing end of the pushing component is connected to the first adjusting roller 41 to move the first adjusting roller 41 toward or away from the first rotating roller 4, thereby achieving the purpose of adjusting the distance between the first rotating roller 4 and the first adjusting roller 41.

[0046] To drive the first rotating roller 4, a first motor (not shown) is mounted on the outer side of one side wall of the frame 1. The output end of the first motor is fixedly connected to the end of the first rotating roller 4. The first rotating roller 4 is offset from the guide roller 3 and positioned below the guide roller 3. The first adjusting roller 41 is spaced apart on the side of the first rotating roller 4 away from the guide roller 3. The first rotating roller 4 and the first adjusting roller 41 are located directly above the sizing assembly. Therefore, the PPS fabric guided by the guide roller 3 passes through the gap between the first rotating roller 4 and the first adjusting roller 41 and then extends directly downward into the sizing assembly.

[0047] The pushing component includes a pushing plate 42 rotatably connected to the inner side wall of the frame 1 and a pushing member 43 hinged to the inner side wall of the frame 1, with the pushing end hinged to the top of the inner side surface of the pushing plate 42. In this embodiment, the pushing member 43 is an electric push rod. An arc-shaped clearance groove 421 is formed in the middle of the side of the pushing plate 42 near the first rotating roller 4. A center rod coaxially arranged with the first adjusting roller 41 is penetrated inside the first adjusting roller 41 and is rotatably connected to the first adjusting roller 41. The clearance groove 421 is used to make way for the center rod. A fixing member 422 extending into the clearance groove 421 is penetrated on the side of the pushing plate 42 away from the first rotating roller 4. The fixing member 422 is connected to the center rod to connect the first adjusting roller 41 to the pushing plate 42. In this embodiment, the fixing member 422 is a fixing bolt that passes through the pushing plate 42 and is threadedly connected to the center rod, thereby achieving a detachable connection between the first adjusting roller 41 and the pushing plate 42.

[0048] In order to limit the adjusted position of the first adjusting roller 41 and reduce the excessive squeezing of the PPS fabric by the first rotating roller 4 and the first adjusting roller 41 due to the small distance between the first rotating roller 4 and the first adjusting roller 41; a limiting member is installed on the inner side wall of the frame 1, and the side of the pushing plate 42 away from the first adjusting roller 41 is rotatably connected to the abutment wheel 423, and the limiting end of the limiting member can be adjusted vertically, and when the pushing member 43 drives the first adjusting roller 41 to move toward the direction close to the first rotating roller 4, the abutment wheel 423 abuts against the limiting end of the limiting member to achieve the purpose of limiting the first adjusting roller 41.

[0049] The limiting member includes a fixing seat 44 vertically mounted on the inner side wall of the frame body 1, a second screw 45 rotatably connected to the fixing seat 44, a slider 46 slidably connected to the fixing seat 44 and threadedly connected to the second screw 45, and a limiting block 47 fixedly connected to the inner side of the slider 46 and abutting the abutting wheel 423. The length direction of the second screw 45 is consistent with the length direction of the fixing seat 44. Therefore, rotating the second screw 45 causes the slider 46 to drive the limiting block 47 to move up and down. The limiting block 47 is provided with an inclined surface on the side close to the abutting wheel 423, which abuts the abutting wheel 423.

[0050] In order to facilitate the rotation of the second screw 45, an extension rod 49 is rotatably connected to the inner wall of the frame 1 and above the fixed seat 44 through a bearing seat 48. The top of the extension rod 49 is fixedly connected to the second handle 491. The bottom end of the extension rod 49 extends into the fixed seat 44 and is fixedly connected to the top of the second screw 45.

[0051] Reference Figure 1 and Figure 6 The slurry coating assembly includes a base 5 installed in the frame 1 and located below the first rotating roller 4 and the first adjusting roller 41, a connecting seat 51 installed in the base 5, a slurry coating tank body 52 installed on the top surface of the connecting seat 51, and a slurry supply component arranged on the top surface of the base 5; the slurry coating tank body 52 is a hollow tank body with an opening at the top, and the two inner side walls of the slurry coating tank body 52 are both inclined downward, the output end of the slurry supply component faces the slurry coating tank body 52, and the slurry supply component can move back and forth along the length direction of the slurry coating tank body 52, so that the slurry supply component supplies external slurry into the slurry coating tank body 52 to supply slurry to the slurry coating tank body 52.

[0052] After being guided by the guide roller 3, the PPS fabric passes through the gap between the first rotating roller 4 and the first adjusting roller 41 and extends vertically downward to the slurry coating assembly. A discharge port 521 is provided on the bottom surface of the slurry coating tank 52, corresponding to and matching the position of the PPS fabric. The discharge port 521 sequentially passes through the connecting seat 51, the base 5, and the frame 1, allowing the slurry-coated PPS fabric to extend through the discharge port 521 to the stabilizing assembly. The discharge port 521, located at the junction of the slurry coating tank 52 and the connecting seat 51, is configured as a narrow opening. The narrow opening only allows the PPS fabric coated with slurry on both sides to pass through, thereby reducing the possibility of slurry in the slurry coating tank 52 leaking out of the narrow opening.

[0053] Reference Figure 6 and Figure 7Two groups of slurry supply components are provided, and the two groups of slurry supply components are symmetrically arranged on both sides of the base 5; the connecting seat 51 is located between the two groups of slurry supply components. Each group of slurry supply components includes an extension seat 53 fixedly connected to the top surface of the base 5, a driving member 54 installed at the end of the extension seat 53, a screw rod 55 rotatably connected to the extension seat 53 and connected to the driving end of the driving member 54, a movable plate 56 slidably connected to the extension seat 53 and threadedly connected to the screw rod 55, and a slurry supply pipe 57 detachably connected to the top surface of the movable plate 56; the length direction of the screw rod 55 is consistent with the length direction of the base 5, so that the slurry supply pipe 57 can slide back and forth along the length direction of the base 5.

[0054] The drive member 54 includes a drive motor and a first reducer mounted on the end face of the base 5. The output end of the drive motor is fixedly connected to the input end of the first reducer, which in turn extends into the extension seat 53 and is fixedly connected to the end of the screw 55. One end of the slurry supply pipe 57 is connected to a slurry supply pump (not shown), which is connected to the slurry. A slurry supply gun 572 is mounted on the end of the slurry supply pipe 57 away from the slurry supply pump. The end of the slurry supply gun 572 away from the slurry supply pipe 57 faces the slurry supply tank. Compared to the method where workers pour slurry from the slurry preparation area into the slurry coating tank 52 through transfer, the slurry supply pump directly pumps slurry from the slurry preparation area into the slurry coating tank, improving work efficiency.

[0055] In order to enable the slurry supply pipe 57 to be installed on the top surface of the movable plate 56, two second limiting rings 571 are fixedly sleeved on the circumference of the slurry supply pipe 57, and a second making way opening for making way for the slurry supply pipe 57 is opened on the top surface of the movable plate 56. When the slurry supply pipe 57 is extended to the second making way opening, the two second limiting rings 571 abut between the two sides of the movable plate 56, and the second making way opening on the top surface of the movable plate 56 is covered with a second cover plate 561. Two vertical second bolts 562 are passed through the top surface of the second cover plate 561. The second bolts 562 pass through the second cover plate 561 and are threadedly connected to the movable plate 56 to fix the second cover plate 561 on the top surface of the movable plate 56.

[0056] To enable the movable plate 56 to automatically reciprocate along the length of the extension base 53, trigger members 58 are mounted on both inner end walls of the extension base 53, with their trigger ends facing the movable plate 56. The trigger members 58 are located above the screw rod 55 and are electrically connected to the drive motor. In this embodiment, the trigger member 58 is a trigger switch, with its trigger end facing the movable plate 56. When the movable plate 56 contacts the trigger end of the trigger switch, the trigger switch causes the drive motor to rotate in the opposite direction.

[0057] Reference Figure 2 and Figure 8The stabilizing assembly includes a second rotating roller 6 rotatably connected between the two inner side walls of the frame 1 and located below the base 5, a first stabilizing member arranged on the circumference of the second rotating roller 6, a power member installed on the outer side wall of the frame 1, a movable member arranged on the inner side wall of the frame 1, a second adjusting roller 61 connected to the movable end of the movable member, and a second stabilizing member arranged on the circumference of the second adjusting roller 61; the second rotating roller 6 and the second adjusting roller 61 are located on the same horizontal plane and are parallel to each other, and the gap between the second rotating roller 6 and the second adjusting roller 61 is located directly below the discharge port 521. The output end of the power member is connected to the end of the second rotating roller 6 so that the second rotating roller 6 can rotate. There are two groups of movable members, and the two groups of movable members are respectively located between the two inner side walls of the frame 1. The second adjusting roller 61 is connected between the two groups of movable members so that the second adjusting roller 61 can move toward or away from the second rotating roller 6.

[0058] The first and second stabilizers are positioned opposite each other, with the PPS fabric passing between them. The first and second stabilizers abut against the side edges of the PPS fabric. In this embodiment, two sets of first stabilizers are provided, with the number of second stabilizers matching the number of first stabilizers in a one-to-one correspondence, ensuring that both side edges of the PPS fabric are stabilized.

[0059] The power component includes a locking seat 62 installed on the outer wall of the frame 1 and a power motor 621 and a second reducer 622 installed on the top surface of the locking seat 62; the output end of the power motor 621 is fixedly connected to the input end of the second reducer 622, and the output end of the second reducer 622 is fixedly connected to a coupling, and the end of the coupling away from the second reducer 622 is fixedly connected to the end of the second rotating roller 6.

[0060] The moving component includes a mounting plate 63 fixedly connected to the inner side wall of the frame 1, a moving member 64 mounted on the end of the mounting plate 63, and a moving block 65 fixedly connected to the moving end of the moving member 64. The mounting plate 63 has an L-shaped cross-section and is mounted with a slide rail 631. The length of the slide rail 631 is consistent with the movement direction of the moving block 65. The moving block 65 is slidably connected to the slide rail 631. The opposite ends of the second adjustment roller 61 are fixedly connected between the two moving blocks 65. In this embodiment, the moving member 64 is also an electric push rod.

[0061] Reference Figure 9 and Figure 10The first stabilizing member is a first abutting sleeve 66 fixedly mounted on the circumferential side of the second rotating roller 6; the second stabilizing member is a second abutting sleeve 67 rotatably connected to the circumferential side of the second adjusting roller 61, and a connecting bearing 671 is provided between the second adjusting roller 61 and the second abutting sleeve 67.
