[0014] By adopting a compaction filtration component, the present invention presses and filters waste gas through a sealing plug, enabling the waste gas to enter the interior of the gas transmission pipe through a pressure permeation filtration strip, ensuring the efficiency of waste gas filtration. During the waste gas filtration process, the rotating component winds up the filtration strip, enabling the filtration strip in contact with the bottom opening of the air collecting cylinder to always maintain the filtration efficiency during the filtration process, without being affected by the increase in internal impurities after filtration. During the pressure filtration, the increased air pressure will push the filtration strip downward to separate it from the air collecting cylinder, resulting in waste gas leakage. However, by tightly pressing the filtration strip between the air collecting cylinder and the gas transmission pipe respectively, the situation of gas leakage can be effectively solved, ensuring that all waste gas can be effectively filtered and discharged through the gas transmission pipe.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Please refer to Figures 1-7The present invention provides a technical solution: a rubber vulcanization waste gas collecting device, comprising a gas collecting cylinder 2, a sealing plug 7 is slidably connected inside the gas collecting cylinder 2, an air supply pipe 6 is arranged at the bottom of the gas collecting cylinder 2, a reeling rack 4 is fixedly connected to the gas supply pipe 6, a reeling rack 5 is arranged at the rear side of the reeling rack 4, a filter strip 3 is rotatably connected to the reeling rack 4, the rear end of the filter strip 3 is rotatably connected to the reeling rack 5, the top end of the filter strip 3 contacts the bottom opening of the gas collecting cylinder 2, and the bottom end of the filter strip 3 contacts the top opening of the gas supply pipe 6, the gas collecting cylinder 2 is provided with a rotating assembly, the rotating assembly comprises an upper frame 24 which can slide upwards, the upper frame 24 is used to make the filter strip 3 fit tightly with the gas collecting cylinder 2 when filtering the exhaust gas inside the gas collecting cylinder 2, the rotating assembly also comprises a fixed gear 13 arranged on the rotating shaft of the reeling rack 5, the fixed gear 13 is used to control the reeling rack 5 to reel the filter strip 3;

[0024] When the above scheme is put into actual use, when filtering the exhaust gas, the external transport pipeline is connected to the air inlet on the side wall of the gas collecting cylinder 2 to connect the sulfide exhaust gas with the gas collecting cylinder 2, and the sealing plug 7 slides upward inside the gas collecting cylinder 2 to generate negative pressure, so that the sulfide exhaust gas is sucked into the gas collecting cylinder 2. When filtering the exhaust gas, the valve of the air inlet pipeline is closed, so that the exhaust gas is pushed into the gas delivery pipe 6 through the bottom opening under the action of the pressure of the sealing plug 7, and the gas will first pass through the filter strip 3 between the gas collecting cylinder 2 and the gas delivery pipe 6. After being filtered by the filter strip 3, the gas is sent from the gas delivery pipe 6 to the next processing equipment. During the downward pressing process of the sealing plug 7, the filter strip 3 is driven to be rolled up on the winding frame 5 through the rotating assembly, and at the same time, the filter strip 3 is upwardly fitted with the bottom opening of the gas collecting cylinder 2, and the filter strip 3 will The filter strip 3 is pressed against the filter cylinder 2 and the filter strip 3 is pressed against the filter cylinder 2 to filter the exhaust gas.

[0025] As a further solution of the present invention, the rotating assembly includes a sliding rod 9 which is slidably arranged inside the air collecting cylinder 2. A sliding groove 8 is formed at the bottom of the sealing plug 7. One end of the sliding rod 9 is slidably arranged inside the sliding groove 8. The rear end of the sliding rod 9 passes through the air collecting cylinder 2 and is arranged outside the air collecting cylinder 2. A connecting rod 12 is fixedly connected to the rear end of the sliding rod 9. A fixed rod 10 is fixedly connected to the bottom of the air collecting cylinder 2. The connecting rod 12 is slidably sleeved inside the fixed rod 10. A first spring 11 for resetting the sliding rod 9 is fixedly connected to the connecting rod 12. A second rack 19 is fixedly connected to the right end of the sliding rod 9. The fixed gear 13 meshes with the second rack 19;

[0026] When the above solution is put into actual use, when the sealing plug 7 slides down to press-filter the waste gas inside the air collecting cylinder 2, the sliding rod 9 will gradually slide towards the outside of the air collecting cylinder 2 along the sliding groove 8 as the sealing plug 7 slides down. The sliding of the sliding rod 9 drives the connecting rod 12 to compress the first spring 11 and slide synchronously. The second rack 19 will also slide synchronously with the sliding rod 9. The sliding of the second rack 19 drives the fixed gear 13 meshing with it to rotate. The fixed gear 13 drives the rotating shaft of the winding frame 5 to rotate, and winds the filter strip 3. At the same time, the unwinding frame 4 at the other end will unwind under the action of the pulling force, ensuring that the bottom opening of the air collecting cylinder 2 contacts different positions on the filter strip 3 for filtration, so that the filtration effect of the filter strip 3 on the waste gas is always the same, and there is no problem of poor filtration effect caused by more filtered impurities.

[0027] As a further solution of the present invention, a connecting plate 17 is fixedly connected to the rear end of the air delivery pipe 6. A first rack 16 is slidably connected to the side wall of the connecting plate 17. A sliding rack 15 is slidably connected to the rear end of the first rack 16. A second spring 14 for resetting it is fixedly connected to the rear end of the sliding rack 15. A one-way bearing 18 is sleeved on the rotating shaft of the winding frame 5. The fixed gear 13 is sleeved outside the one-way bearing 18. A fixing plate 20 is fixedly connected to the left end of the first rack 16. A push rod 21 is fixedly connected to the front end of the fixing plate 20. The front end of the push rod 21 slidably passes through the air delivery pipe 6 and is arranged on the front side of the air delivery pipe 6. The upper top frame 24 is slidably arranged inside the air delivery pipe 6. A first clamping groove 22 for slidably connecting with the bottom of the upper top frame 24 is formed on the push rod 21;

[0028] When the above scheme is put into actual use, when the second rack 19 drives the fixed gear 13 to rotate, the fixed gear 13 will drive the first rack 16 meshing at the bottom to slide, and the first rack 16 pushes the push rod 21 to slide toward the front side of the gas pipe 6, so that the upper frame 24 pushes the upper frame 24 to slide upward through the first slot 22, and the upper frame 24 moves up to contact the bottom of the filter strip 3, and gradually pushes the filter strip 3 to slide upward, so that the filter strip 3 below the bottom opening of the gas collecting cylinder 2 gradually bulges upward and extends to the inside of the filter strip 3, thereby realizing the effect of sealing the gas collecting cylinder 2 through the filter strip 3 from the bottom of the gas collecting cylinder 2, ensuring that during the filter press, a large pressure will not cause the filter strip 3 to break away from the seal with the gas collecting cylinder 2.

[0029] As a further solution of the present invention, a connecting block 30 is fixedly connected to the gas delivery pipe 6, a push block 26 is slidably connected to the side wall of the connecting block 30, the bottom of the push block 26 is in contact with the push rod 21, the top of the push block 26 is fixedly connected to a fourth rack 29, the front end of the gas delivery pipe 6 is rotatably connected to a transmission gear 28 meshing with the fourth rack 29, a lower pressure ring 23 is provided on the top of the gas delivery pipe 6, the front end of the lower pressure ring 23 is fixedly connected to a sleeve frame 25, and the bottom of the sleeve frame 25 is fixedly connected to a third rack 27 meshing with the transmission gear 28;

[0030] When the above scheme is put into actual use, when the push rod 21 extends forward, the push rod 21 will push the push block 26 to slide upward through the groove at the front end, and the push block 26 will drive the fourth rack 29 to slide upward, and the fourth rack 29 drives the transmission gear 28 to rotate, and the transmission gear 28 will drive the third rack 27 to slide downward, and the third rack 27 drives the sleeve frame 25 and the lower pressure ring 23 to slide downward, so that the lower pressure ring 23 presses down the filter strip 3, so that the filter strip 3 at the top of the gas pipe 6 is wrapped downward on the top of the gas pipe 6. In this way, when the upper frame 24 pushes the filter strip 3 upward to seal tightly with the gas collecting cylinder 2, the filter strip 3 can be pressed down again so that the filter strip 3 and the gas pipe 6 are tightly sealed, so as to avoid the problem of a gap between the bottom of the filter strip 3 and the gas pipe 6 due to the convexity of the filter strip 3, so that the filtered exhaust gas will not leak from the top of the gas pipe 6.

[0031] As a further solution of the present invention, the top of the gas collecting cylinder 2 is fixedly connected to a hydraulic unit 1, and the output shaft of the hydraulic unit 1 passes through the gas collecting cylinder 2 and is fixedly connected to a sealing plug 7;

[0032] When the above scheme is put into actual use, when controlling the sealing plug 7 to slide up and down, the sealing plug 7 is driven to slide by the hydraulic unit 1. Since the friction between the sealing plug 7 and the inner wall of the gas collecting cylinder 2 is relatively large, the sealing plug 7 can be effectively driven to slide up and down by the hydraulic unit 1.

[0033] As a further solution of the present invention, the outer walls of the sliding rods 9 are all smooth walls, the sliding rods 9 can be completely fitted with the inner walls of the sliding grooves 8, and a sealing washer is sleeved on the outer edge of the sealing plug 7;

[0034] When the above solution is put into actual use, being completely fitted together enables the sliding rod 9 to effectively drive the sliding rod 9 to slide downward when sliding inside the sliding groove 8, and through the sealing coupon, it can effectively ensure that the sealing plug 7 is tightly attached to the inner wall of the air collecting cylinder 2 to avoid the leakage of waste gas.

[0035] As a further solution of the present invention, a support frame 31 is fixedly connected to the bottom of the air collecting cylinder 2, and one end of the filter strip 3 passes through the support frame 31 and is rotatably connected to the winding frame 5;

[0036] When the above solution is put into actual use, by adjusting the angle of the filter strip 3 through the support frame 31, the filter strip 3 can be wound on the winding frame 5 while ensuring that the filter strip 3 is taut.

[0037] As a further solution of the present invention, annularly distributed ball mounting grooves are provided at the top of the upper top frame 24 and the bottom of the lower pressing ring 23;

[0038] When the above solution is put into actual use, the balls can effectively reduce the extrusion force of the upper top frame 24 and the lower pressing ring 23 on the filter strip 3, avoiding problems such as tearing or inability to slide of the filter strip 3 caused by excessive extrusion force.

[0039] Working principle: When filtering waste gas, it is docked with the air inlet on the side wall of the air collecting cylinder 2 through an external transportation pipeline to connect the sulfurized waste gas with the air collecting cylinder 2. A negative pressure is generated by the upward sliding of the sealing plug 7 inside the air collecting cylinder 2 to suck the sulfurized waste gas into the air collecting cylinder 2. When filtering waste gas, the valve of the intake pipeline is closed, so that under the pressure of the sealing plug 7, the waste gas is pushed through the opening at the bottom and discharged into the gas transmission pipe 6. When the sealing plug 7 slides down to press-filter the waste gas inside the air collecting cylinder 2, the sliding rod 9 will gradually slide outward along the chute 8 as the sealing plug 7 slides down. The sliding of the sliding rod 9 drives the connecting rod 12 to compress the first spring 11 and slide synchronously. The second rack 19 will also slide synchronously with the sliding rod 9. The sliding of the second rack 19 drives the fixed gear 13 meshed with it to rotate. The fixed gear 13 drives the rotating shaft of the winding frame 5 to wind the filter strip 3. At the same time, the unwinding frame 4 at the other end will unwind under the action of the pulling force to ensure that the opening at the bottom of the air collecting cylinder 2 contacts different positions on the filter strip 3 for filtration, so that the filtration effect of the filter strip 3 on the waste gas is always the same. When the second rack 19 drives the fixed gear 13 to rotate, the fixed gear 13 will drive the first rack 16 engaged at the bottom to slide. The first rack 16 pushes the push rod 21 to slide forward on the front side of the gas transmission pipe 6, so that the upper top frame 24 is pushed upward through the first card slot 22. The upper top frame 24 moves upward to contact the bottom of the filter strip 3 and gradually pushes the filter strip 3 to slide upward, so that the filter strip 3 below the opening at the bottom of the air collecting cylinder 2 gradually bulges upward and extends into the filter strip 3, thus realizing the function of sealing the air collecting cylinder 2 through the filter strip 3 from the bottom of the air collecting cylinder 2. When the push rod 21 extends forward, the push rod 21 will push the push block 26 to slide upward through the groove at the front end. The push block 26 will drive the fourth rack 29 to slide upward. The fourth rack 29 drives the transmission gear 28 to rotate. The transmission gear 28 will drive the third rack 27 to slide downward. The third rack 27 drives the socket frame 25 and the pressing ring 23 to slide downward, so that the pressing ring 23 presses the filter strip 3, so that the filter strip 3 at the top of the gas transmission pipe 6 wraps downward around the top of the gas transmission pipe 6. In this way, when the upper top frame 24 pushes the filter strip 3 upward to be tightly sealed with the air collecting cylinder 2, the filter strip 3 can be pressed downward so that the filter strip 3 is tightly sealed with the gas transmission pipe 6, thus avoiding the problem of gaps between the bottom of the filter strip 3 and the gas transmission pipe 6 caused by the upward convexity of the filter strip 3, and preventing the filtered waste gas from leaking outside from the top of the gas transmission pipe 6.
