Technical Field

[0001] The utility model relates to the technical field of metal waste processing, in particular to a metal waste drum drying device. Background Art

[0002] Rotary kiln is a heat treatment equipment, mainly used for sintering, calcining and pyrolysis of materials. It is widely used in metallurgy, building materials, chemical industry and environmental protection industries. In the metallurgical industry, it is mainly used for smelting metal ores and recycling metal waste.

[0003] After searching, a Chinese patent disclosed CN201810807612.X (publication number CN109059533B). Although this patented technology filters and recovers the smoke and hot air emitted from the rotating connection of the rotary kiln cylinder, the filter screen is cleaned by an air pump, and the gas discharged from the tail of the rotary kiln is not mentioned, which leads to the need for additional tail exhaust gas recovery and treatment equipment, increasing the cost of metal scrap processing. Therefore, those skilled in the art provide a metal scrap drum drying device to solve the problems raised in the above background technology. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figure 1-4The utility model provides an embodiment of a metal scrap drum drying device, comprising a kiln body 1, a power mechanism 2, a cylinder 3, a dryer 4, a smoke exhaust pipe 5, a connecting cover 6 and a filter screen 8. A power mechanism 2 is provided on the outside of the kiln body 1, and the cylinder 3 is rotatably installed at both ends of the kiln body 1. The bottom of the cylinder 3 is equipped with a bearing seat for supporting the cylinder 3. The power mechanism 2 includes a main gear ring, a main gear, a motor and a reducer. The main gear ring is installed at the middle end of the outer side of the kiln body 1. The main gear ring and the main gear are the same size as the gear ring 1001 and the gear 1003. The front end is crowned with "main" to distinguish them. The two ends of the reducer are respectively connected to the motor and the main gear, and the main gear is engaged with the main gear ring. When in use, the speed of the motor is reduced by the reducer to drive the main gear to rotate, and the main gear ring is driven to rotate, thereby realizing the rotation of the kiln body 1.

[0030] Preferably: the top of the cylinder 3 at one end is connected to a feed hopper, and the bottom of the cylinder 3 at the other end is connected to a discharge hopper. The outsides of the feed hopper and the discharge hopper are equipped with pneumatic gate valves, which control the flow of metal scrap in the feed hopper and the discharge hopper through the pneumatic gate valves to avoid waste gas from being emitted from the feed hopper and the discharge hopper to pollute the environment during processing.

[0031] A dryer 4 is installed on the outside of the cylinder 3 at one end, and a smoke exhaust pipe 5 is connected to the outside of the cylinder 3 at the other end. A filter 8 is installed inside the smoke exhaust pipe 5. When in use, the dryer 4 is started to allow hot air to enter the cylinder 3 and the kiln body 1 to dry the metal scrap inside the cylinder 3 and the kiln body 1. The smoke generated by drying is filtered through the filter 8 inside the smoke exhaust pipe 5 and then discharged.

[0032] Preferably: a connecting cover 6 is installed on the outer side of the connection between the kiln body 1 and the cylinder 3, and a first connecting pipe 7 is connected between the smoke exhaust pipe 5 and the connecting covers 6 at both ends. The first connecting pipe 7 is communicated with the inside of the smoke exhaust pipe 5 and is located at one end of the filter screen 8, and a second connecting pipe 9 is connected between the smoke exhaust pipe 5 and the cylinder 3 at the other end. The smoke exhaust pipe 5 and the cylinder 3 at the other end are both provided with a cavity, and the second connecting pipe 9 is communicated with the cavity. The connecting cover 6 plays the role of closing the connection between the kiln body 1 and the cylinder 3 to prevent smoke and dust from overflowing at the connection. When in use, the smoke and dust at the connection between the kiln body 1 and the cylinder 3 enters the interior of the smoke exhaust pipe 5 through the connecting cover 6 and the first connecting pipe 7, and is discharged after being filtered through the filter screen 8. When the filter screen 8 filters the smoke, the speed of the smoke slows down, and the heat in the smoke is physically conducted and concentrated in the cavity of the smoke exhaust pipe 5, and enters the cavity of the cylinder 3 at the other end through the second connecting pipe 9, thereby realizing heat recovery and reuse.

[0033] A cleaning assembly 10 is provided at one end of the filter 8, and the cleaning assembly 10 includes a ring gear 1001 and a rotating rod 1002. The ring gear 1001 is installed on the outside of the kiln body 1, and the rotating rod 1002 is rotatably installed on the top of the connecting cover 6 near one end of the smoke exhaust pipe 5. A gear 1003 meshing with the ring gear 1001 is installed at one end of the rotating rod 1002, and a transmission rod 1004 is installed at the other end of the rotating rod 1002. A slider 1005 is rotatably installed at the end of the transmission rod 1004 away from the connection with the rotating rod 1002, and a slide plate 1006 is slidably connected to the outer side of the slider 1005. A connecting rod 1007 is installed at the bottom of the slide plate 1006, and a scraper 1008 is installed at the bottom end of the connecting rod 1007. A sliding hole matching the size of the connecting rod 1007 is provided on the top of the smoke exhaust pipe 5, and the scraper 1008 is slidably connected to one end of the filter 8.

[0034] During use, the power mechanism 2 drives the kiln body 1 to rotate, the kiln body 1 drives the ring gear 1001 to rotate, the ring gear 1001 drives the gear 1003 to rotate, the gear 1003 drives the rotating rod 1002, the transmission rod 1004 and the slider 1005 to rotate, and the slider 1005 slides inside the slide plate 1006 when rotating, driving the slide plate 1006 to move back and forth, and the slide plate 1006 drives the connecting rod 1007 and the scraper 1008 to move back and forth. When the scraper 1008 moves, it cleans the metal waste filtered on the filter screen 8, avoiding the problem of reduced filtering effect caused by clogging of the mesh of the filter screen 8, without the need to increase the power source, and reducing the cost of metal waste processing.

[0035] Preferably: a mounting plate 11 is also installed on the outside of the cylinder 3 at the other end, a storage box 12 is slidably connected to the top of the mounting plate 11, a channel is installed at the bottom inside the exhaust pipe 5, the channel is located at one end of the filter screen 8, and a through hole adapted to the size of the channel is opened on the top of the storage box 12.
