Description

Technical Field

[0001] This utility model belongs to the field of rotary kiln technology, specifically relating to a double-layer rotary kiln device. Background Technology

[0002] A rotary kiln is a high-temperature processing device used to heat materials to high temperatures through continuous calcination. Traditional rotary kilns generate flue gas during operation, which can have a negative impact on the health of workers if they inhale it. Although existing technologies can extract and purify the flue gas, their overall structure often has certain shortcomings in use, thus requiring improvement.

[0003] Chinese patent CN218155439U discloses a double-layer sealed rotary kiln, belonging to the field of rotary kiln technology. It includes a kiln tail smoke chamber, a cylinder, and a kiln head hood. A base plate is bolted to the bottom of the kiln tail smoke chamber, cylinder, and kiln head hood. Sealing devices are installed on both sides of the cylinder. A support plate is bolted to the back of the top of the base plate, and a spray box and a filter box are bolted to the top of the support plate from left to right. An air supply pipe is connected to the center of the bottom of the filter box. Through the cooperation of a three-way pipe, air supply pipe, air inlet hood, and fan, dust is drawn into the filter box. The air drawn into the filter box is filtered through the cooperation of a first filter screen, a second filter screen, a rotating shaft, a drive gear, a driven gear, a lead screw, a threaded block, and a locking block. The air is sprayed and settled through the cooperation of a water pump, a connecting frame, and spray nozzles, purifying the air and preventing dust from affecting the environment and being inhaled by the user.

[0004] However, although the above-mentioned technical solutions can achieve the purpose of filtering and purifying flue gas, in actual use, especially when too many impurities accumulate on the filter plate, the filtration effect of the filter plate is easily reduced, and the surrounding working environment is difficult to purify. At the same time, the staff need to disassemble and clean the filter plate, which is cumbersome and delays the progress of flue gas purification work, and has certain limitations in use.

The support cavity 4 secures the filter chamber 5 within it. The filter chamber 5 also secures the drive motor 6, which provides a driving force for the rotation of the cam 7. The positioning rod and guide sleeve 8 allow the push rod 9 to move up and down within the cam 7, which provides power to move it up and down according to its rotation trajectory. The sliding groove 10 allows the filter plate 11 to move up and down within it. One side of the filter plate 11 only slides within the sliding groove 10, contacting its inner wall. (Further details omitted for brevity.) The filter can be separated from the sliding groove 10. The filter plate 11 is set to filter the flue gas entering the filter chamber 5. There are two filter plates 11 to improve the filtration effect. The fixed block 13 is set to allow the baffle plate 14 to rotate. The electric telescopic rod 16 and the movable clamp 17 are set to pull the baffle plate 14 up to a certain height, so that the discharge chute 12 can be opened, allowing the impurities on the filter plate 11 to be shaken and discharged.

[0029] Example 2:

[0030] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, an L-shaped support block 20 is slidably connected inside the guide groove 19, and connecting blocks 21 are fixedly connected to both sides of the filter plate 11. Screws are threaded inside the L-shaped support block 20, and the surface threads of the screws penetrate the interior of the connecting block 21. A collection groove is provided at the bottom of one side of the support cavity 4, and a collection drawer 36 is provided inside the collection groove. Two connecting rods 22 are provided inside the filter chamber 5, and connecting columns are fixedly connected to both ends of the connecting rods 22, and the surface threads of the connecting columns are connected to the interior of the filter plate 11. The L-shaped support block 20 supports the two filter plates 11. The connecting block 21 and screws connect and fix the filter plates 11 to the L-shaped support block 20, facilitating subsequent disassembly. The collection drawer 36 collects impurities that roll down through the filter plates 11. One end of the collection drawer 36 abuts against the bottom of the filter chamber 5 for better collection. The connecting rod 22 connects the two filter plates 11. The connecting rod has threads on its surface, and the threads on both ends are in opposite directions, making it easy to screw into the two filter plates 11 simultaneously.

[0031] The working principle of this utility model is as follows: The operator pre-controls the start of the fan 23. Air is drawn in through the suction pipe 24 from the fan 23's inlet end. The suction force is then transmitted to the filter chamber 5, sequentially through the connecting pipe 25, the connecting pipe 26, the suction pipe 27, the extraction pipe 29, and the suction hood 30. The suction hood 30 extracts the flue gas located near the cylinder 2. The gas then enters the filter chamber 5, passing through two filter plates 11, where impurities in the flue gas are filtered out. It then enters the air supply pipe 31 at the fan 23's outlet end, and finally enters the water storage chamber 32, located in the space above the partition. At this time, the operator controls the water pump 33 to operate. The water inlet pipe of the water pump 33 delivers water to the outlet pipe of the water pump 33, and then the water enters the fixed rod 34 through the water inlet pipe. Finally, the water enters the atomizing nozzle 35 through the fixed rod 34, causing the atomizing nozzle 35 to atomize the water and spray it onto the filtered gas, purifying it. The purified gas is discharged through the exhaust pipe. The fixed rod 34 has a hollow structure to facilitate the passage of water. When there are many impurities on the filter plate 11, it will affect its filtration effect. At this time, the operator controls the drive motor 6 and the electric telescopic rod 16 to start, driving... The output of motor 6 drives cam 7 to rotate. The rotation of cam 7 causes push rod 9 to move up and down, which in turn causes push rod 9 to push the filter plate 11 located below, causing it to move up and down through guide groove 19 and sliding groove 10. This causes some of the impurities accumulated on filter plate 11 to roll downwards. At this time, electric telescopic rod 16 retracts, which pulls movable clamp 17, causing baffle plate 14 to rotate a certain angle through the rotating shaft inside fixed block 13. This causes baffle plate 14 to open, allowing the impurities and particles accumulated on filter plate 11 to fall downwards and finally enter the collection drawer 36 for collection. To facilitate centralized processing by staff, when it is necessary to disassemble the filter plate 11, the staff should first open the inspection door, and then open the blocking plate 14 through the electric telescopic rod 16. At this time, the staff only needs to unscrew the screws, and then separate the connecting block 21 from the L-shaped support block 20. Then, the two filter plates 11 can be pulled out to the outside. After the filter plates 11 are removed, the staff can rotate the connecting rod 22 to unscrew the connecting column from the inside of the two filter plates 11. The other side of the filter plate 11 separates from the sliding groove 10. The staff can then clean the filter plate 11.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
