Detailed Description

The present invention will be further explained with reference to fig. 1.

Referring to figure 1: a rotary cage circulating air drying system comprises an air inlet chamber 1, an air outlet chamber 2, a drying chamber 4 and a rotary cage 12. The air inlet chamber 1 is communicated with the air outlet chamber 2, a primary air filter 6 and a secondary air filter 7 are arranged between the air inlet chamber 1 and the air outlet chamber 2, the primary air filter 6 is arranged on one side close to the air inlet chamber 1, and the secondary air filter 7 is arranged on one side of the air outlet of the primary air filter 6. A fan 8 is arranged in the air outlet chamber 2, the air outlet of the fan 8 is communicated with an air inlet pipe 11, the fan 8 is communicated with the drying chamber 4 through the air inlet pipe 11, and a high-efficiency air filter 10 is arranged in the air inlet pipe 11; the side wall of the air outlet chamber 2 is also provided with a first emptying pipe 9, and the first emptying pipe 9 is provided with a control valve. Meanwhile, a heating wire is arranged in the fan 8, and blowing air can be heated to improve drying efficiency.

A rotating cage 12 is arranged in the drying chamber 4, the drying chamber 4 is communicated to the air inlet chamber 1 through a circulating pipeline 3, one end of the circulating pipeline 3 is communicated to one end of the rotating cage 12 far away from the air inlet pipe 11, the other end of the circulating pipeline 3 is communicated to one side of the air inlet chamber 1, a fresh air pipe 5 is further arranged on the other side of the air inlet chamber 1, and a control valve is arranged on the fresh air pipe 5.

The other end of the drying chamber 4 far away from the air inlet pipe 11 is also provided with a second emptying pipe 13, and the second emptying pipe 13 is provided with a control valve.

Before new equipment is started, the fresh air pipe 5 is externally connected with purging gas, the second emptying pipe 13 is opened to purge and dry the whole rotating cage circulating air drying system by using fresh air, and the environmental stability is ensured. During normal use, will treat that the product that dry sweeps is put into the rotating cage 12 in, close fresh air pipe 5, first evacuation pipe 9 and second evacuation pipe 13, start fan 8, the heater strip circular telegram heats simultaneously, realizes the product heating drying in the rotating cage 12 to the drying process does not have outer exhaust gas, does not need tail gas treatment, and most aqueous vapor, product dust can finally concentrate on just imitating air cleaner 6, last certain time sweep the back and accomplish the drying. The water blocking limit of the primary air filter, the intermediate air filter and the high-efficiency air filter is benefited, and excessive drying caused by excessive blowing can be effectively avoided.

After the rotating cage circulating air drying system is used for a certain number of times or time, self-cleaning can be carried out, the fan 8 is turned reversely, the fresh air pipe 5 and the first exhaust pipe 9 are opened, the fresh air pipe 5 supplies new purging air to the system, the fresh air passes through the air inlet chamber 1, the circulating pipeline 3, the drying chamber, the air inlet pipe 11, the efficient air filter 10 and the fan 8 in sequence and then enters the air outlet chamber 2, and finally the fresh air is discharged from the system through the first exhaust pipe 9, the reverse blowing regeneration of the circulating pipeline 3, the drying chamber 4, the air inlet pipe 11 and the efficient air filter 10 is realized, the service lives of the efficient air filter 10 and the whole system can be effectively prolonged, the cleaning degree and the product drying quality are ensured, and the first exhaust pipe 9 needs to be externally connected with a tail gas treatment device to protect the environment. The appropriate hot-blast heating to each air cleaner can be realized to 8 blowbacks in-processes of fan to the heater strip circular telegrams to evaporation moisture is through reverse circulation from the 9 discharge systems of first exhaust pipe, realizes the drying to entire system, prolongs each air cleaner's life.

After primary self-cleaning, the first emptying pipe 9 needs to be closed, the fresh air pipe 5 and the second emptying pipe 13 are opened to perform primary forward purging, and then the air filter is normally used, so that the shape of each air filter is ensured to be restored to a normal state.
