Dryer chamber structure

Abstract

The present invention relates to a dryer chamber structure using an organic solvent with an improved structure which constructs a dryer chamber in a multi-level structure to supply hot air in a heating zone on an upper side to both left and right of a hot air supply duct arranged in a drying zone on a lower side to uniformly supply the temperature of hot air to improve drying performance, and hasa first and a second crater in the drying zone and the heating zone to prevent deformation of the chamber and improve safety of workers. The dryer chamber structure using the organic solvent comprises: a dryer chamber of a multi-level structure having a heating zone on an upper side with respect to a barrier and a drying zone on a lower side of the barrier; at least one first crater arranged on aceiling of an upper portion of the heating zone; a second crater arranged on at least one door arranged on the front surface or the rear surface of the drying zone to be opened and closed, and provided with an explosion-proof door hinge-connected to the door to be opened by an explosion pressure when an explosion occurs in the drying zone; and a guide member arranged on the front side of the explosion-proof door of the second crater arranged on the door to guide an explosion pressure and flames ejected through the second crater in an upward direction and limit an opening amount by interferingwith an upper portion when the explosion-proof door opens.

Description

technical field [0001] The present invention relates to a drier chamber structure using an organic solvent, and more particularly to a drier chamber that can be constructed by forming a multi-layer structure and supplying hot air in a heating zone on the upper side to a drying chamber equipped on the lower side. The left and right sides of the hot air supply duct in the zone can supply hot air with uniform temperature to improve the drying performance, and at the same time, it can prevent the deformation of the chamber and prevent the deformation of the chamber by installing the first and second blast holes in the drying zone and heating zone. A dryer chamber structure using an organic solvent with an improved structure that enhances worker safety. Background technique [0002] Generally, a Multi-Layer Ceramic Capacitor (hereinafter referred to as MLCC) is a component used to temporarily store charges, and is recently developing towards ultra-miniaturization, ultra-high capa...

Problems solved by technology

[0011] However, because of the structural characteristics of the existing dryer chamber, the hot air in the heating zone is unidirectionally supplied to the right end of the hot air supply pipe, so the temperature difference between one side of the above hot air supply pipe and the other side of the hot air will be different. Unevenness leading to reduced drying uniformity of multilayer ceramic capacitors (MLCC) or rechargeable battery products

[0012] In addition, in the existing chambers using organic solvents, because of the characteristics of volatile organic solvents, they may be converted into explosive gases when they are concentrated and cannot be discharged to the outside. There may also be a risk of the dryer exploding due to the above-mentioned explosive gas

[0013] When the above-mentioned phenomenon of dryer explosion occurs, the explosion pressure and flame will be discharged to the outside through the part of the chamber of the dryer that is not enough to withstand the pressure, and the above-mentioned explosion pressure and flame discharged to the outside will be transmitted to the When the operator is performing the operation, it will cause the danger of the operator's safety accident

[0014] In order to improve it, it is possible to separately equip the upper part of the chamber of the dryer with the explosion pressure and flame ejection channel, that is, the blast hole, but there is a limitation that it can only be formed in the upper part of the chamber that does not affect the walking of workers. Moreover, because the heating zone and the drying zone of the existing dryer are respectively formed on the left and right sides, the installation space is limited due to the large volume in the width direction. In order to overcome the above problems, a multi-layer structure chamber is used. In the dry area, it is necessary to set a blast hole above a certain specification in the dry area, which leads to the problem that the requirements of the current safety regulations cannot be met.

[0015] In addition, the dust generated when the dryer explodes as described above is deposited on the bottom of the dryer chamber, but because of the structural characteristics of the existing dryer chamber, it causes a problem that it is difficult to clean it thoroughly, and Dust remaining inside the dryer chamber will be a major factor in deteriorating the quality of multilayer ceramic capacitors (MLCC) or rechargeable battery products passing through the dryer chamber
