Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of feeding device, concretely relates to a drying furnace discharging and feeding device. BACKGROUND

[0002] The drying furnace is one of the commonly used equipment in the production process of semi coke, and its main purpose is to dry the semi coke. In the drying of semi coke, the control of moisture is very important. If the moisture control is not good, it will affect the subsequent process and the final calcium carbide product.

[0003] At present, the semi coke drying is to place the semi coke in the drying furnace, gradually remove the moisture in it through appropriate temperature and airflow control, and then prepare the finished semi coke through the sealed conveying equipment (such as the belt) for the next process as the production raw material of calcium carbide. Although the belt can realize the feeding of the finished semi coke, there are the following problems:

[0004] (1) In the existing feeding of dried semi coke, in order to dry the flying semi coke, the discharge port of the drying furnace is often inserted into the conveying equipment, but since the drying furnace is placed vertically and the conveying equipment is placed horizontally, an angle is formed between them, so that the center part of the discharge port of the drying furnace has a high flow rate, the part close to the outer wall of the drying furnace has a low flow rate, and the flow rates inside and outside are inconsistent, which not only makes the discharging uneven, but also causes the material to accumulate on the outside due to the slow flow rate on the outside, thereby causing a large temperature difference between the inner arc plate and the outer arc plate in the drying furnace, resulting in uneven moisture during the drying of semi coke and reducing the qualified rate of the finished semi coke;

[0005] (2) When there is a large temperature difference between the inside and outside of the drying furnace, since the moisture of the semi coke raw material entering the drying machine is large, the frequency of the conveying equipment must be reduced to reduce the moisture of the finished semi coke, but this easily causes the deposition of coke fines at the discharge end, resulting in uneven discharging. At the same time, reducing the frequency of the belt reduces the discharging speed, which causes the furnace temperature index of the drying furnace to exceed the process index range, resulting in a too high inlet temperature of the drying furnace, which in turn causes the semi coke to appear red, resulting in unqualified finished semi coke. When the inlet temperature of the drying furnace is too high, it will cause a large area of the drying furnace to catch fire, causing the arc plate of the drying furnace to deform and affecting the service life of the drying furnace.

[0006] In summary, the existing drying furnace feeding mainly has the defects of a large temperature difference between the inner arc plate and the outer arc plate, which in turn causes uneven moisture, uneven discharging and unqualified finished semi coke. UTILITY MODEL CONTENTS
