Description

Technical Field

[0001] The utility model relates to the technical field of roller kiln head smoke exhaust, in particular to a roller kiln head smoke exhaust structure. Background Art

[0002] The roller kiln uses high temperature resistant ceramic sticks to directly drive the refractory board forward. The refractory board loaded with products is directly carried on the sticks. It is also called a roller kiln. The earliest introduction was to burn wall and floor tiles. There was no pallet. The floor tiles were directly placed on the sticks. Due to the extremely small temperature difference during the preheating, burning and cooling process, the burning time was shortened from more than ten hours in the past using shuttle kilns and tunnel kilns to dozens of minutes. It also gradually changed from low temperature type to medium and high temperature type. The kiln head of the roller kiln will emit a lot of smoke when in use, so a special smoke exhaust structure is required to exhaust the smoke.

[0003] According to the patent with publication number CN216620639U, a smoke exhaust device for a roller kiln for ceramic-based composite materials is disclosed, including a roller kiln body and an upper filter plate, the upper end surface of the roller kiln body is provided with a smoke exhaust port, the upper end of the smoke exhaust port is connected to a smoke exhaust pipe, the upper filter plate is arranged on the upper surface of the smoke exhaust pipe, the lower end surface of the upper filter plate is provided with a sealing gasket, the lower end of the sealing gasket is provided with a filter screen plate, the lower end of the filter screen plate is provided with a positioning protrusion, and the lower end of the positioning protrusion is provided with the upper filter plate.

[0004] By adopting the above scheme, the dust in the gas can be filtered through the filter screen, so as to prevent the dust particles in the gas from being discharged to the outside. However, the filter plate is installed inside the smoke exhaust pipe, and the filter plate often needs to be taken out and cleaned regularly. When there is too much dust in the smoke, workers will disassemble and clean the filter plate more frequently. The above scheme is not convenient for automatically cleaning the filter plate to delay the cycle of disassembling and cleaning the filter plate, and there are certain shortcomings. For this reason, we provide a roller kiln head smoke exhaust structure to solve the above problems. Utility Model Content

[0024] A driving mechanism 5 is arranged above the filtering mechanism 4, and the driving mechanism 5 includes an insulating base 501. The insulating base 501 is a pad with an insulating function to prevent the motor 502 from being subjected to too much heat from the smoke exhaust pipe 3. The outer surface of the insulating base 501 is fixedly connected to the outer surface of the smoke exhaust pipe 3, and the motor 502 is installed on the inner wall of the insulating base 501. A connecting rod 503 is installed at the output end of the motor 502, and a cam 504 is fixedly connected to the left end of the connecting rod 503.

[0025] By starting the motor 502 , the connecting rod 503 and the cam 504 can be driven to rotate, so that the cam 504 can repeatedly press the smoke filter plate 401 .

[0026] A load-bearing and rocking mechanism 6 is arranged below the filtering mechanism 4, and the load-bearing and rocking mechanism 6 includes an electric push rod 601 and a load-bearing groove 605. The inner wall of the load-bearing groove 605 is in contact with the outer surface of the smoke collecting groove 402. By using the set load-bearing groove 605, the handle 403 can be supported and protected. The top of the electric push rod 601 is fixedly connected with a heat-insulating connecting seat 607. The outer surface of the heat-insulating connecting seat 607 is fixedly connected to the outer surface of the smoke exhaust pipe 3. By using the set heat-insulating connecting seat 607, the heat of the smoke exhaust pipe 3 can be prevented from being transferred to the electric push rod 601, causing the electric push rod 601 to overheat.

[0027] The output end of the electric push rod 601 is rotatably connected to the bearing plate 602. A relatively strong welding should be used between the electric push rod 601 and the bearing plate 602. The upper surface of the bearing plate 602 is fixedly connected to the bottom plate 603. The inner wall of the bottom plate 603 is slidably connected to two supporting slide bars 604. The top ends of the two supporting slide bars 604 are fixedly connected to the bottom surface of the bearing groove 605. The outer surfaces of the two supporting slide bars 604 are wrapped with return springs 606. The upper and lower ends of the two return springs 606 are fixedly connected to the bottom surface of the bearing groove 605 and the upper surface of the bottom plate 603.

[0028] By using the two reset springs 606 , the bearing slot 605 can be shaken, which can drive the smoke collecting slot 402 to shake, so that the dust on the outer surface of the smoke filter plate 401 can fall into the inside of the smoke collecting slot 402 .

[0029] A purification chamber 7 is installed on the outer surface of the roller kiln body 1, and an activated carbon multilayer composite plate 8 is installed inside the purification chamber 7. By using the activated carbon multilayer composite plate 8, the flue gas can be purified.

[0030] One end of the smoke exhaust pipe 3 close to the purification chamber 7 is connected to the inner top wall of the purification chamber 7. A sealed opening and closing door 10 is installed on the front of the purification chamber 7. By using the set sealed opening and closing door 10, the activated carbon multi-layer composite board 8 can be conveniently replaced. The inner bottom wall of the purification chamber 7 is fixedly connected with an exhaust pipe 9, and the set exhaust pipe 9 should be connected to the pipe for exhausting air.

[0031] Working principle: When the device needs to be used, first open the roller kiln body 1 to start working, and the generated smoke is discharged from the smoke outlet 2 into the inside of the smoke exhaust pipe 3. The smoke can be filtered through the smoke filter plate 401, and the smoke is filtered by the activated carbon multilayer composite plate 8 and discharged through the exhaust pipe 9 connected to the external pipeline. By starting the motor 502, the connecting rod 503 and the cam 504 can be driven to rotate, so that the cam 504 can repeatedly press the smoke filter plate 401. Under the elastic force of the two return springs 606, the bearing groove 605 and the smoke filter plate 401 can be driven to shake, so that the dust on the outer surface of the smoke filter plate 401 can be shaken off to the inside of the smoke collection tank 402, thereby delaying the cycle of disassembling the smoke filter plate 401 for cleaning. By using two handles 403, the smoke collecting trough 402 and the smoke filter plate 401 can be held, and by starting the electric push rod 601, the supporting plate 602, the bottom plate 603 and the supporting trough 605 can be driven to move downward, and then the supporting trough 605 is rotated and removed from under the smoke collecting trough 402, so that the smoke filter plate 401 and the smoke collecting trough 402 can be pulled out of the exhaust pipe 3, so that the smoke filter plate 401 can be thoroughly cleaned and the dust stored in the smoke collecting trough 402 can be cleaned conveniently.
