Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hot blast stove, in particular to a hot blast stove drying assembly. BACKGROUND

[0002] Traditional hot blast stove drying assemblies perform poorly in terms of material heating uniformity. Usually, a simple hot air direct blowing method is adopted, and the distribution of hot air in the stove is uneven, leading to uneven heating of the material. Some areas may be overheated due to the concentration of hot air, while other areas may not be heated enough, which not only affects the drying effect, but also may lead to inconsistent material quality. For example, in some traditional drying equipment, the material close to the hot air source is prone to excessive drying or even scorching, while the material far from the hot air source is not dried thoroughly, affecting the overall quality and performance of the product.

[0003] For static drying methods, most traditional equipment lacks effective material tumbling or rotating mechanisms. The material is in a relatively static state during the drying process, with limited contact area with hot air, resulting in slow water evaporation speed and low drying efficiency. Moreover, due to insufficient contact of different parts of the material with hot air, large local humidity differences may occur, further affecting the drying quality.

[0004] The above information disclosed in the background section of this document is only intended to increase the understanding of the background of the present application, and therefore, it may include information that is not prior art known to those of ordinary skill in the art. CONTENT OF THE UTILITY MODEL

[0005] To solve the problem of uneven distribution of hot air in the stove, leading to uneven heating of the material, and some areas may be overheated due to the concentration of hot air, while other areas may not be heated enough, which not only affects the drying effect, but also may lead to inconsistent material quality, the present application provides a hot blast stove drying assembly.

[0006] The hot blast stove drying assembly provided by the present application adopts the following technical solution:

[0007] A hot blast stove drying assembly, comprising a hot blast stove, a hot air jacket fixed to one end of the hot blast stove, a protective cover covering the outside of the hot air jacket, a connecting pipe connected between the hot blast stove and the protective cover, a circulating air pipe fixed outside the connecting pipe, a ventilation filter screen detachably installed on the outer wall of the hot air jacket near the protective cover, a circulating air chamber opened in the inside of the hot air jacket, the circulating air chamber extending into the hot blast stove, a drying chamber opened in the center of the inside of the hot blast stove, and a heating inner container installed in the drying chamber.

[0008] Preferably, an air inlet pipe is installed on the center of the outer wall of the hot blast stove, a circulating air port is provided on the air inlet pipe, and one end of the connecting pipe is connected with the circulating air port.

[0009] Preferably, the hot blast furnace is provided with supporting legs at the bottom, and the hot blast jacket is provided with a feeding pipe, and the heating liner is provided with a feeding port at the top of one end, and the feeding port is provided with a sealing plug.

[0010] Preferably, the heating liner is provided with a connecting flange at one end of the outer wall, and the connecting flange is externally connected with a sealing plate.

[0011] Preferably, the sealing plate is rotationally connected with the inner wall of the hot blast jacket, and the protective cover is internally provided with a servo motor at the center.

[0012] Preferably, the output end of the servo motor penetrates the inner wall of the protective cover and is drivingly connected with the sealing plate, and the outer wall of the heating liner is circumferentially provided with a plurality of ventilation holes.

[0013] In summary, the present application has the following beneficial technical effects:

[0014] The present application is provided with a circulating air chamber in the hot blast furnace, and a heating liner is arranged in the circulating air chamber. The heating liner is wrapped by the circulating air chamber, which can ensure the uniformity of the heating of the internal materials. The heating liner rotates circumferentially in the drying chamber, so that the hot blast uniformly flows through the ventilation holes, ensuring that each part of the heating liner can receive uniform hot blast, avoiding local overheating or overcooling, and improving the uniformity of drying. Compared with static drying, the dynamic drying method can make each part of the material fully contact the hot blast, thereby accelerating the evaporation speed of the moisture. The hot blast is filtered by the ventilation filter screen, discharged to the inside of the protective cover, and then circulated and delivered to the hot blast furnace through the connecting pipe and the circulating air pipe. The hot blast circulating system greatly saves heat energy resources and reduces energy consumption. BRIEF DESCRIPTION OF DRAWINGS
