Problems solved by technology

This treatment method can only avoid the harm of condensate to the equipment, but cannot fundamentally solve the generation of condensate, and not only affects the production capacity (once a month), but also consumes a large amount of protective gas, which is expensive and inefficient

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 and figure 2 As shown, the atmosphere-protected roller kiln of this embodiment includes a furnace body 1 having a furnace 11, a material conveying device 2 arranged in the furnace 11, and a first device connected to the furnace 11 for introducing protective gas into the furnace 11. Intake device (not shown in the figure), the furnace 11 is divided into a heating section 111, a constant temperature section 112 and a cooling section 113 along the direction from the inlet to the outlet. The heating section 111 and the constant temperature section 112 are provided with heating devices 3. The furnace 11 is also provided with a smoke exhaust section 114 , the smoke exhaust section 114 is located between the heating section 111 and the inlet of the furnace 11 , and the smoke exhaust section 114 is connected with the...

Abstract

The invention discloses an atmosphere protection roller kiln which comprises a furnace, a material conveying device and first gas inlet devices. The furnace is provided with a hearth, the material conveying device is arranged in the hearth, the first gas inlet devices are used for filling the hearth with protective gas, the hearth is sequentially divided into a temperature rise section, a constant-temperature section and a temperature reduction section along the direction from an inlet to an outlet, heating devices are arranged in the temperature rise section and the constant-temperature section, the hearth is further provided with a smoke exhaust section, the smoke exhaust section is positioned between the temperature rise section and the inlet of the hearth, and a first gas exhaust device is connected with the smoke exhaust section. The atmosphere protection roller kiln has the advantages that the atmosphere protection roller kiln is long in service life and low in energy consumptionand can stably and reliably work, the quality of products can be improved, and the like.

Description

technical field [0001] The invention relates to the technical field of heat treatment equipment, in particular to an atmosphere-protected roller kiln. Background technique [0002] Atmosphere roller kiln is a commonly used equipment for material heat treatment. The atmosphere-protected roller kiln for silicon-carbon anode materials used in the preparation of silicon-carbon anode materials by high-temperature pyrolysis is divided into three parts: a heating section, a constant temperature section, and a cooling section. Dao kiln puts forward higher requirements, which are manifested in: [0003] The material contains a large amount of volatile matter, which will be produced in large quantities in the range of 200-400°C in the heating section. If these volatile matter cannot be discharged in time, it will affect the working environment of the equipment and cause the sensor to fail; Under the influence of gravity, it grows downward along the side wall of the furnace, and is c...
