Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3A non-condensable gas purification device for a calcining furnace includes a connecting pipe 1 and a rotating column 13. A clearance groove is provided on the right side of the connecting pipe 1, extending through both the front and rear sides of the connecting pipe 1. A rotating shaft 21 is fixedly installed on the right side of the inner wall of the clearance groove. The left side of the outer wall of the rotating column 13 is located within the clearance groove. A through hole is provided at the top of the rotating column 13, and the rotating shaft 21 is rotatably installed within the through hole, allowing the rotating column 13 to rotate. A first mounting hole is provided on the left side of the top of the rotating column 13, and a second mounting hole is provided on the right side of the top of the rotating column 13. The first mounting hole is located within the clearance groove and is connected to the connecting pipe 1. A ceramic filter element 3 is placed within the first mounting hole. A quick-release assembly is placed on the outside of the connecting pipe 1. Two sets of annular grooves are evenly distributed on the outer wall of the ceramic filter element 3. A heat-resistant sealing ring 31 is fixedly installed in the groove. The outer wall of the heat-resistant sealing ring 31 is in contact with the inner wall of the first mounting hole. The opposite sides of the two sets of heat-resistant sealing rings 31 are respectively in contact with the upper and lower sides of the inner wall of the relief groove. The heat-resistant sealing ring 31 seals the connection gap between the ceramic filter element 3 and the rotating column 13, as well as the connection gap between the ceramic filter element 3 and the connecting pipe 1. A third mounting hole is evenly opened on the inner wall of the first and second mounting holes. A second spring 32 is fixedly installed in the third mounting hole. A round-headed pin 33 is fixedly installed on the outer side of the second spring 32. A positioning hole is evenly opened on the outer wall of the ceramic filter element 3. The round head of the round-headed pin 33 located in the first mounting hole is inserted into the positioning hole, and the ceramic filter element 3 is installed in the first mounting hole. Then, the second spring 32 located in the first mounting hole will drive the round-headed pin 33 on its outer side to insert into the positioning hole, thereby limiting the ceramic filter element 3 in the first mounting hole. The top of the connecting pipe 1 is connected to the air outlet pipe 11, and the bottom of the connecting pipe 1 is connected to the air inlet pipe 12. A set of push-pull grooves 4 are opened on both the front and rear sides of the rotating column 13, connecting the air inlet pipe 12 to the exhaust port of the calcining furnace. At this time, the non-condensable gas generated by the calcining furnace will enter the first mounting hole of the rotating column 13 through the air inlet pipe 12 and come into contact with the ceramic filter element 3. After the non-condensable gas is purified and filtered by the ceramic filter element 3, it will be discharged through the air outlet pipe 11. The top left side of the connecting pipe 1 has a first insertion hole, and the bottom left side of the connecting pipe 1 has a second insertion hole. The top left and right sides of the rotating column 13 are respectively opened with The first locking hole and the second locking hole are respectively provided on the left and right sides of the bottom of the rotating column 13. The quick-release assembly includes a guide sleeve 14 and a hand-tightening bolt 2. The guide sleeve 14 is fixedly installed on the left side of the connecting pipe 1. A guide rod 15 is slidably installed inside the guide sleeve 14. The bottom of the guide rod 15 passes through the bottom of the guide sleeve 14 and is connected to a pressure plate 18. The top of the guide rod 15 passes through the top of the guide sleeve 14 and is connected to a connecting plate 16. A pin 19 is fixedly installed on the bottom right side of the connecting plate 16. The bottom of the pin 19 passes through the first insertion hole and is inserted into the first locking hole, corresponding to the second locking hole. A first spring 17 is installed on the outer ring of the guide rod 15. The first spring 17 is fixedly installed between the guide sleeve 14 and the connecting plate 16.The first spring 17 drives the connecting plate 16 downward, thereby causing the pin 19 to pass through the first insertion hole of the connecting pipe 1 and be inserted into the first locking hole of the rotating column 13, thus fixing the rotating column 13 inside the connecting pipe 1. Then, the hand-tightening bolt 2 passes through the second insertion hole of the connecting pipe 1 and is screwed into the first threaded hole at the bottom of the rotating column 13, thus reinforcing the rotating column 13 inside the connecting pipe 1, thereby ensuring stable communication between the first mounting hole of the rotating column 13 and the connecting pipe 1. The hand-tightening bolt 2 passes through the second insertion hole and is screwed into the first threaded hole, and the second threaded hole corresponds to the first threaded hole.

[0019] Working principle: After the ceramic filter element 3 is installed in the first mounting hole, the second spring 32 located in the first mounting hole will drive the round-headed pin 33 on its outer side to insert into the positioning hole, thereby limiting the ceramic filter element 3 in the first mounting hole. The first spring 17 drives the connecting plate 16 to move downward, thereby driving the pin 19 to pass through the first insertion hole of the connecting pipe 1 and insert into the first locking hole of the rotating column 13, thereby fixing the rotating column 13 in the connecting pipe 1. Then, the hand-tightening bolt 2 passes through the second insertion hole of the connecting pipe 1 and screws it into the first threaded hole at the bottom of the rotating column 13, thereby reinforcing the rotating column 13 in the connecting pipe 1, thereby making the first mounting hole of the rotating column 13 and the connecting pipe 1 stably connected. The air inlet pipe 12 is connected to the exhaust port of the calcining furnace. At this time, the non-condensable gas generated by the calcining furnace will enter the first mounting hole of the rotating column 13 through the air inlet pipe 12 and come into contact with the ceramic filter element 3. After the non-condensable gas is purified and filtered by the ceramic filter element 3, it is discharged through the air outlet pipe 11.

[0020] When a new ceramic filter element 3 needs to be replaced, simply insert the new ceramic filter element 3 into the second mounting hole of the rotating column 13. At this time, the second spring 32 located in the second mounting hole will drive the round-headed pin 33 on its outer side to insert into the positioning hole, thereby limiting the new ceramic filter element 3 in the second mounting hole. Then, after the hand-tightening bolt 2 is separated from the first threaded hole of the rotating column 13, the upward-moving pressure plate 18 drives the pin 19 to move upward and separate from the first locking hole of the rotating column 13 through the guide rod 15 and the connecting plate 16. At this time, the rotating column 13 can be pushed to rotate around the rotating shaft 21 through the push-pull groove 4. When the second locking hole of the rotating column 13 is aligned with the pin 19, the hand-tightening bolt 2 will be aligned with the second threaded hole. The connecting pipe 1 will be connected to the second mounting hole. At this time, the pressure plate 18 is released, and the first spring 17 uses its own rebound force to drive the pin 19 to move downward and insert into the second locking hole through the connecting plate 16. Then, the hand-tightening bolt 2 is screwed into the second threaded hole to fix the rotating column 13 in the connecting pipe 1, thereby making the second mounting hole and the connecting pipe 1 stably connected. At this time, the new ceramic filter element 3 in the second mounting hole will replace the old ceramic filter element 3 in the first mounting hole to perform non-condensable gas purification work, while the old ceramic filter element 3 in the first mounting hole will move out of the connecting pipe 1 as the rotating column 13 rotates. At this time, by pressing down on the old ceramic filter element 3, it can overcome the elastic force of the second spring 32 and slide out of the first mounting hole.
