Description

Technical Field

[0001] The utility model relates to the technical field of pellet chain grates, in particular to a pellet chain grates with an auxiliary burner. Background Art

[0002] The pellet chain grate is a widely used equipment in pellet production. It transports the pellet material from one end to the other through the circular motion of the chain, and performs drying, preheating and roasting during the transportation process. The pellet chain grate has the advantages of high efficiency, energy saving and environmental protection, and can effectively improve production efficiency and product quality. Its work flow usually includes feeding, drying, preheating, roasting and discharging stages. The pellet material goes through these steps on the chain grate and gradually forms finished pellets that meet the requirements.

[0003] When the pellet chain grate is preheating, first, high-temperature gas will pass through the grate bed of the chain grate, which can heat the pellet material to a certain temperature. At the same time, the pellets will also exchange heat with the grate bed and its surrounding components during transportation, thereby achieving preheating. In addition, parameters such as the operating speed of the chain grate and the temperature of the hot air flow will also affect the preheating effect.

[0004] However, the preheated high-temperature gas will not achieve the preheating effect due to heat loss when flowing inside the chain grate, so the burner head needs to be auxiliary heated. The burner head is in working state for a long time and needs timely maintenance and replacement, but it is inconvenient to maintain and replace it inside the chain grate, which is not conducive to ensuring the efficient working efficiency of the chain grate. Therefore, a pelletizing chain grate with an auxiliary burner is proposed to solve the above problems. Utility Model Content
