Cooler for rotary furnace

Abstract

The invention discloses a cooler for a rotary furnace, which solves the problem that the existing device consumes energy, is large in investment and has ignition lost of carbon. The cooler for the rotary furnace is characterized in that a material collecting chamber is arranged on the external surface at a discharge end of a shell of the rotary furnace. The material collecting chamber comprises a large diameter section and a small diameter section. The large diameter section of the material collecting chamber is arranged at a discharge / feed port, and the small part of the large diameter section is dipped in a cooling pool. The small diameter section of the material collecting chamber is provided with a discharge device which consists of a separation plate, a rotary shaft and an opening rod. According to the cooler for the rotary furnace, broiling carbon is not contacted with external air to combust and can be cooled rapidly so as to be discharged out of the furnace at a lower temperature, so that the product is free from ignition loss, the yield is guaranteed and the quality is further improved at the same time. No special devices are additionally arranged, the operational process is simplified and the occupied area is reduced. The cooler for the rotary furnace can be used not only for an internal thermal rotary furnace, but also for an external thermal rotary furnace. Meanwhile, the cooler for the rotary furnace can be used in other fields utilizing the rotary furnace.

Description

Technical field [0001] The present invention relates to a cooler, more precisely to a cooler for a rotary kiln for the production of activated carbon. Background technique [0002] At present, in the process of using the rotary kiln to produce activated carbon, there are many kinds of cooling methods used for cooling the new carbon in a hot state. For example: some manufacturers use a special screw conveyor (cooling medium can be added in the interlayer of the casing) for cooling treatment: some manufacturers use rotating drums for cooling: some manufacturers spray on the surface of new charcoal in a hot state Water mist: some simply discharge the hot charcoal into the cooling water pool for cooling. There are a series of problems in these cooling methods: 1. they all need to allow new charcoal to be discharged outside the body of heater under the hot state, and then go to the equipment used for cooling treatment. This kind of cooling method requires additional equipment s...

AI Technical Summary

Problems solved by technology

There are a series of problems in these cooling methods: 1. They all need to allow new charcoal to be discharged outside the furnace body in a hot state, and then transfer to the equipment used for cooling treatment

This kind of cooling method requires additional equipment specially used to drive power to work normally. possible

2. The method of spraying and watering directly affects the quality of the product, and sometimes it needs to be dried again to meet the standard requirements of the product
