Hot blast stove of drying equipment

Abstract

The invention discloses a hot blast stove of drying equipment. The hot blast stove structurally comprises a stove body, supports, an air inlet door and a combustor. Airflow generated by swinging of heat mixing bodies exerts airflow force on rotating bodies to enable the rotating bodies to continuously rotate around bearings, circulation of heat gas is disturbed in a certain flow direction at a flow discharging opening, circulation of spark foam carried in the gas is blocked on the inner side of a middle partition mechanism and stays and suspends for a long time, so that sparks are cooled and extinguished conveniently, inclined impact blocks deform obliquely under the action of airflow force to extinguish the spark foam carried in the gas, circulation and mixing of the gas are accelerated through hinged swing movement of the heat mixing bodies, swing of hinge swing plates has interaction force on airflow, at the moment when the hinge swing plates move in the opposite direction of the airflow, the spark foam can be extinguished through beating under elastic cooperation of springs, a displacement ring conducts multi-directional annular displacement movement to drive chisel columns tobe inserted in different positions in a radial cavity in a penetrating manner, the spark foam flowing through the chisel columns are extinguished through chisel columns, and therefore the spark foam in the mixed gas is eliminated.

Description

technical field [0001] The invention belongs to the field of drying equipment, and more specifically relates to a hot blast stove of the drying equipment. Background technique [0002] Drying equipment is usually a device that uses warm and hot air to dry the materials to be dried. As its thermal power machine, the hot air stove generates heat by burning coal, gas, etc., and mixes it with circulating air through the heating surface to make it a Hot air, and then conduct the hot gas to the drying equipment. [0003] Based on the inventor's discovery above, the hot blast stove of existing drying equipment has the following deficiencies: [0004] The hot gas generated after the fuel is burned in the combustion chamber is circulated outdoors and mixed with the outside air. Since the hot gas will carry the burnt fuel slag, it also contains sparks and the residual temperature cools slowly, and mixes with the air. Finally, they are discharged from the hot air outlet together to s...

Problems solved by technology

[0004] The hot gas generated after the fuel is burned in the combustion chamber is circulated outdoors and mixed with the outside air. Since the hot gas will carry the burnt fuel slag, it also contains sparks and the residual temperature cools slowly, and mixes with the air. After that, they will be discharged from the hot air outlet together to supply heat to the drying equipment, which will easily cause ash to adhere to the equipment and affect the use of the equipment.
