Description

Technical Field

[0001] The utility model relates to the technical field of eucalyptus board processing equipment, in particular to a drying kiln for eucalyptus rotary cut veneer. Background Art

[0002] Eucalyptus rotary cut veneer is a common wood unit processed from eucalyptus. Due to its straight trunk shape and easy rotary cutting process, eucalyptus rotary cut veneer is often used to make plywood, recombined wood and other wood-based panel products. Before processing, eucalyptus rotary cut veneer needs to be dried to reduce the moisture content to meet the requirements of wood-based panel production process. However, during the drying process of eucalyptus, it is extremely easy to crack, deform, and the moisture content distribution is uneven after drying. At present, the drying of eucalyptus rotary cut veneer is mainly carried out by air drying or drying machine drying. Air drying takes a long time, the moisture content after drying is relatively high, and the drying quality is not good. Conventional drying machine drying has high energy consumption and requires manual on-site operation in real time.

[0019] The following combines the drawings to describe the specific implementation manners of the present utility model in detail, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation manners.

[0020] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or variations thereof such as "comprises" or "comprising" will be understood to include the stated element or component and not to exclude other elements or other components.

[0021] As Figures 1 to 2 Shown in the figure, a drying kiln for eucalyptus veneer according to a specific embodiment of the present utility model includes a kiln body 1. The bottom of the kiln body 1 is provided with a hollow through hole to form an air inlet 11, and the air inlet 11 is communicated with a blowing mechanism (not shown in the figure). When drying operation is carried out, the blowing mechanism conveys hot air into the kiln body through the air inlet 11. An air outlet 12 is provided at the top of the kiln body 1, and the air outlet 12 is communicated with an air delivery pipe to discharge the gas through the air delivery pipe. Preferably, a plurality of air outlets 12 are provided, and are regularly distributed in a point pattern on the top of the kiln body. The plurality of point-distributed air outlets can make the hot air rising from the bottom linger in the kiln body 1 for a period of time and then be discharged outside the kiln body, so that the boards are heated evenly. At the same time, the air outlet 12 and the air inlet 11 form a convection, which can timely discharge the water vapor after drying. The rear side of the kiln body 1 is in a sealed state, and an opening 13 is provided on the front side, and a door 14 that can be opened and closed is provided at the opening 13. A bottom plate 2 with a mesh structure is laid at the bottom of the kiln body 1, and the bottom plate is made of a mesh iron plate material. A fixing frame 3 is provided in the kiln body 1.

A plurality of fixing grooves 33 are evenly distributed on each fixing rod 31. A plurality of movable rods 32 are horizontally arranged parallel to each other at intervals, and are located between the fixing rods 31 on both sides of the kiln body. The two ends of the movable rod 32 are inserted into the fixing grooves 33 of the fixing rod 31. The space between the movable rods 32 forms a swing plate space for placing the boards to be dried.

[0022] During assembly, the two ends of the movable rod 32 are inserted into the fixing grooves 33 of the fixing rods on the left and right sides of the kiln body. The movable rod 32 is horizontally arranged. Then, the boards are arranged. After the boards 5 are arranged, another movable rod 32 is inserted into the adjacent fixing grooves 33, that is, a swing plate space is formed between two adjacent movable rods, and the boards are fixed within this space range, and there are still gaps at the same time. When drying, hot air is introduced through the air inlet below, and the hot air flows upward through the bottom plate 2 below to blow the boards and is discharged from the air outlet above the kiln body to complete the drying operation.

[0023] Preferably, a plurality of limiting rods 4 are arranged in the kiln body 1. The plurality of limiting rods 4 are arranged parallel to each other on the same horizontal plane, horizontally between the fixed rods 32 arranged on both sides of the kiln body. The plurality of limiting rods 4 are connected to the fixed rods 32 to form a limiting frame, and the limiting frame is located above the movable rod 32. Preferably, the gap spaces formed between adjacent limiting rods 4 and the swing plate spaces between two adjacent movable rods are arranged corresponding to each other. When the swing plate is carried out, the upper end of the plate is inserted into the upper gap space, and the lower part is placed in the swing plate space.
