DETAILED DESCRIPTION

[0023] In order to further connect the features, technical means and specific objectives and functions achieved by the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Reference Figure 1-Figure 5 A boiler furnace cover fixed sealing structure comprises a furnace cover body 101, a boiler body 102 is arranged below the furnace cover body 101, a mounting frame 103 is arranged inside the furnace cover body 101, a plurality of limit plates 106 are symmetrically arranged on the mounting frame 103, a sealing gasket 104 is slidably arranged on the inner wall of the mounting frame 103 between the limit plates 106, and a mounting platform 105 is arranged inside the mounting frame 103; an adjusting mechanism 200 for adjusting the distance between the sealing gasket 104 and the inner wall of the boiler body 102 is arranged on the mounting platform 105; a wiping mechanism 300 for wiping the sealing gasket 104 and a drainage mechanism 400 for discharging the wiped water are arranged on the adjusting mechanism 200.

[0025] The adjusting mechanism 200 is used to adjust the distance between the sealing gasket 104 and the boiler body 102 so as to improve the sealing performance. The water on the sealing gasket 104 can be wiped by the wiping mechanism 300, and the wiped water is discharged through the drainage mechanism 400, thus preventing the sealing gasket 104 from being affected by water vapor for a long time, which causes its aging to accelerate, and is not conducive to improving its service life.

[0026] Reference Figure 1-Figure 3 : The adjusting mechanism 200 includes a motor 201, a rotating disk 202, a connecting arm 203, a pushing block 204 and a mounting block 205. The motor 201 is installed on the top wall of the furnace cover body 101, and the output end of the motor 201 passes through the top wall of the furnace cover body 101 and connects to the top wall of the rotating disk 202. A plurality of mounting blocks 205 are provided on the mounting platform 105. The rotating disk 202 is slidably provided on the mounting blocks 205. The mounting blocks 205 are all provided with slide grooves, and pushing blocks 204 are slidably provided in the slide grooves. A plurality of connecting arms 203 are hingedly installed on the rotating disk 202, and the other end of the connecting arm 203 is hingedly matched with the side wall of the pushing block 204.

[0027] The starting motor 201 drives the rotating disk 202 to rotate. By rotating the rotating disk 202 and cooperating with the connecting arm 203, the connecting arm 203 pushes the push block 204 to slide in the slide groove in the mounting block 205, thereby realizing the push block 204 to move back and forth in the slide groove of the mounting block 205.

[0028] Reference Figure 2-Figure 4 The wiping mechanism 300 includes an inclined groove 301, a limiting slider 302, a connecting block 303, an installation arc plate 304, a water absorbing block 305 and a receiving plate 306. The installation block 205 is symmetrically provided with inclined grooves 301, and a limiting slider 302 is slidably provided in the inclined groove 301. The side wall of the limiting slider 302 is installed on the side wall of the connecting block 303. The connecting block 303 is provided with a receiving plate 306 on the top wall. The receiving plate 306 is provided with an installation arc plate 304. The bottom wall of the installation arc plate 304 is installed with a water absorbing block 305, and the water absorbing block 305 cooperates with the sealing gasket 104.

[0029] The push block 204 moves back and forth to drive the limit slider 302 to slide in the inclined groove 301. The limit slider 302 moves upward while sliding. The limit slider 302 drives the connecting block 303, the installation arc plate 304, the water absorption block 305 and the receiving plate 306 to move upward at the same time, so as to prevent the water absorption block 305 from affecting the movement of the sealing gasket 104. When the work is completed and the water vapor on the sealing gasket 104 needs to be wiped, the push block 204 drives the sealing gasket 104 to retract. At this time, the limit slider 302 slides and moves upward at the same time. It moves downward, gradually driving the water absorbent block 305 to move downward and wipe the sealing pad 104. Since the cross-section of the water absorbent block 305 is trapezoidal and elastic, it can wipe the sealing pad 104. While the water absorbent block 305 moves downward, it can cooperate with the water absorbent sponge 107 to provide a squeezing force on the sealing pad 104. Since both the water absorbent block 305 and the water absorbent sponge 107 are elastic, they will not cause damage to the sealing pad 104, and such squeezing force can squeeze out the absorbed water and collect it through the collection groove 402.

[0030] Reference Figure 2-Figure 4 : A water-absorbing sponge 107 is provided on the side wall of the mounting block 205, one end of the pushing block 204 passes through the water-absorbing sponge 107 to connect to the sealing pad 104, and the water-absorbing sponge 107 cooperates with the water-absorbing block 305.

[0031] The back and forth movement of the mounting block 205 can drive the sealing gasket 104 to move back and forth, thereby adjusting the distance between the sealing gasket 104 and the boiler body 102 and improving the sealing performance. The water-absorbing sponge 107 is used to absorb the water vapor on the sealing gasket 104.

[0032] Reference Figure 2-Figure 5The drainage mechanism 400 includes a mounting ring 401, a collecting groove 402, a pull rod 403, a push plate 404, a connecting shaft 405, a piston 406, a collecting water tank 407, a mounting frame 408 and a connecting water pipe 409. The mounting ring 401 is installed below the water-absorbing sponge 107 between the mounting platform 105 and the mounting frame 103. The mounting ring 401 is provided with a collecting groove 402. The mounting frame 408 is installed on the bottom wall of the mounting platform 105. The collecting water tank 407 is installed on the mounting frame 408. The piston 406 is slidably arranged in the collecting water tank 407. One end of the piston 406 is connected to the connecting shaft 405. The other end of the connecting shaft 405 passes through the side wall of the collecting water tank 407 and is connected to the push plate 404. The side wall of the push plate 404 is connected to the pull rod 403. The other end of the pull rod 403 is connected to the side wall of the connecting block 303. The collecting water tank 407 is provided with a connecting water pipe 409 at one end close to the mounting platform 105. The upper end of the connecting water pipe 409 is connected to the collecting tank 402. The collecting water tank 407 is connected to the inner wall of the mounting frame 103 at one end through a connecting pipe. The drainage groove 108 is arranged on the inner wall of the mounting frame 103 and the inner wall of the limiting plate 106. The other end of the drainage groove 108 is connected to the drainage pipe 109 arranged on the side wall of the furnace cover body 101.

[0033] The back and forth movement of the connecting block 303 can drive the pull rod 403 to move back and forth. When the absorbent sponge 107 and the absorbent block 305 squeeze the sealing gasket 104, the pull rod 403 retracts and drives the push plate 404, the connecting shaft 405 and the piston 406 to retract. At this time, the squeezed water can be collected in the collection water tank 407. When the connecting block 303 drives the sealing gasket 104 to seal the boiler body 102, since valves are provided on the drain pipe 109 and the connecting water pipe 409, the collected water can be discharged out of the equipment through the drain groove 108 and the drain pipe 109.

[0034] Reference Figure 1-Figure 4 : A sealing ring is provided at one end of the limiting plate 106 close to the boiler body 102.

[0035] The sealing performance between the boiler body 102 and the furnace cover body 101 is improved.

[0036] Working principle:

[0037] S1. The starting motor 201 drives the rotating disk 202 to rotate. The rotating disk 202 rotates and cooperates with the connecting arm 203, so that the connecting arm 203 pushes the push block 204 to slide in the slide groove of the mounting block 205, so that the push block 204 moves back and forth in the slide groove of the mounting block 205. The back and forth movement of the mounting block 205 can drive the sealing gasket 104 to move back and forth, so as to adjust the distance between the sealing gasket 104 and the boiler body 102, thereby improving the sealing performance. The water-absorbing sponge 107 is used to absorb the water vapor on the sealing gasket 104;

[0038] S2, the push block 204 moves back and forth to drive the limit slider 302 to slide in the inclined groove 301, and the limit slider 302 moves upward while sliding, and the limit slider 302 drives the connecting block 303, the installation arc plate 304, the water absorption block 305 and the receiving plate 306 to move and move upward at the same time, so as to avoid the water absorption block 305 affecting the movement of the sealing gasket 104. When the work is completed and the water vapor on the sealing gasket 104 needs to be wiped, the push block 204 drives the sealing gasket 104 to retract, and at this time, the limit slider 302 slides and moves upward at the same time. The water absorbing block 305 is moved downward, and gradually drives the water absorbing block 305 to move downward and wipe the sealing pad 104. Since the cross section of the water absorbing block 305 is trapezoidal and elastic, the sealing pad 104 can be wiped. When the water absorbing block 305 moves downward, it can cooperate with the water absorbing sponge 107 to provide a squeezing force on the sealing pad 104. Since both the water absorbing block 305 and the water absorbing sponge 107 are elastic, they will not cause damage to the sealing pad 104, and such squeezing force can squeeze out the absorbed water and collect it through the collecting groove 402.

[0039] S3, the back and forth movement of the connecting block 303 can drive the pull rod 403 to move back and forth. When the water-absorbing sponge 107 and the water-absorbing block 305 squeeze the sealing gasket 104, the pull rod 403 retracts and drives the push plate 404, the connecting shaft 405 and the piston 406 to retract. At this time, the squeezed water can be collected in the collection water tank 407. When the connecting block 303 drives the sealing gasket 104 to seal the boiler body 102, since valves are provided on the drain pipe 109 and the connecting water pipe 409, the collected water can be discharged through the drain groove 108 and the drain pipe 109. And discharged out of the equipment, like this, the water vapor on the sealing gasket 104 can be wiped clean in time and the wiped water can be collected and processed, thus avoiding the sealing gasket 104 from being affected by water vapor, thereby causing its aging speed to accelerate, which is not conducive to improving the service life of the equipment, and the sealing gasket 104 is affected by water vapor and rots, and it is not convenient for the staff to repair it faster, thus improving work efficiency, saving manpower, facilitating operation, simplifying the maintenance process, and reducing maintenance time, and the collected squeezed water is directly discharged out of the equipment during work, and no manual operation is required.

[0040] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
