Air chamber for baking oven and baking oven

Abstract

The invention discloses an air chamber for a baking oven and the baking oven. The air chamber comprises a body and a cover plate which is covered on the body to form a cavity together with the body. The cover plate is provided with a plurality of slantly distributed vent holes, and the air chamber is further provided with an air inlet. According to the air chamber, due to the fact that the vent holes are slantly arranged, air flow can reach all positions of products, and the products can be dried fully.

Description

technical field [0001] The invention belongs to the technical field of ovens, and relates to an air chamber for an oven and an oven. Background technique [0002] Drying the wet blank of the paper mold generally adopts the heating dehumidification method. The principle is: remove the moisture in the solid material with the help of heat energy, this operation is to use a certain heating method to transfer heat to the material, so that the moisture in the wet material is vaporized and separated, so as to obtain less moisture content. solid dry material. Convective drying is widely used at present. The preheated gas is contacted with the wet material, and the heat in the gas is transferred to the material by convection, so that the moisture is vaporized, and the vaporized moisture is taken away by the gas. In the previous equipment, an air channel is arranged on the upper and lower sides of the drying box, and there are conveying chain plates or support rods between the upper...

Problems solved by technology

[0004] 1. Usually, the upper and lower air passages enter the air from one side. When the bellows is relatively long, because the openings on the side facing the wet billet are uniform, when the blower has a large wind pressure, the wind blows out from the end of the bellows. The wind speed is higher; on the contrary, when the wind pressure of the blower is small, the wind speed at the outlet of the hole from the inlet end of the bellows is relatively high. During the whole conveying process of the dried product, due to the change of moisture content, the quality gradually decreases, but the wind speed is not constant, so it is easy to be blown away from the support rod or chain plate

[0005] 2. Because the air outlet of the bellows is opened on a flat plate, although the openings are very regular, it is difficult to adapt to the wet products of paper molds with different structures. Some industrial packaging paper products have complex structures, and the hot air blown by the bellows It is often in contact with higher and more prominent parts, and some corners of the wet billet are difficult to contact with hot air, which will cause the wet billet to be deformed due to inconsistent drying and wet speeds during drying.

[0006] 3. Because the top and bottom of the drying tunnel are single air ducts, it is difficult to independently control the wind speed of each section of the drying tunnel
