Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, and in particular to a particleboard drying device. Background Technology

[0002] Wood shavings are long pieces of wood chips produced during wood processing. They have a wide range of uses; after being crushed, they can be used to make high-pressure laminates. High-pressure laminates made from wood shavings and chips are widely used in furniture production. Before use, the wood shavings need to be dried.

[0003] Traditional particleboard drying equipment generally suffers from problems such as low heat utilization, poor drying uniformity, insufficient control precision, and prominent safety hazards: most equipment uses an open hot air system, resulting in serious heat loss; some circulation structures have high energy consumption due to the lack of a dehumidification mechanism; it relies on manual experience for operation, lacks real-time temperature and humidity monitoring and closed-loop feedback system, and makes it difficult to accurately control drying parameters.

[0004] Therefore, a particleboard drying device is proposed to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-2 This utility model discloses a particleboard drying device, including a device body 1. The device body 1 consists of a hot air box 2 and a fixed box 3. The hot air box 2 is fixedly installed on the top of the fixed box 3 by bolts. The front end of the fixed box 3 is provided with a switch door 301. The surface of the switch door 301 is embedded with a display screen 302. The right end is equipped with a latch 303 by a hinge.

[0023] Eight U-shaped heat-generating pipes 202 are arranged horizontally inside the hot air box 2. The heat-generating pipes 202 are fixed to the inner wall of the hot air box 2 by ceramic supports, and arc-shaped guide plates are set between adjacent heat-generating pipes 202. An air inlet 201 is opened on the right side surface of the hot air box 2, and an axial flow fan 203 is connected to the center of the bottom end through a flange. The air outlet 304 of the fan 203 is welded to the bottom plate of the hot air box 2 to form a sealed air inlet channel. A safety pressure relief valve is installed on the top of the hot air box 2, which automatically opens when the internal pressure exceeds 0.3MPa.

[0024] The fixed box 3 contains a stainless steel processing tank 305 with dimensions of 1200×800×500mm. The bottom of the processing tank 305 is supported by four weighing sensors, which are electrically connected to a display screen 302 on the surface of the switch door 301 via shielded wires. The processing tank 305 contains a stirring assembly, including two parallel mixing rollers 306. Spiral-arranged stirring paddles 307 are welded to the surface of the mixing rollers 306, with the two rollers spiraling in opposite directions to form a counter-conveyor structure. The right end of the mixing rollers 306 is synchronously driven by a gear set, and each roller is connected to a reducer at its left end. The input shaft of the reducer is connected to the output shaft of the drive motor via a coupling.

[0025] The rear end of the fixed box 3 has an air outlet 304, which is connected to the air inlet 201 of the hot air box 2 via a 200mm diameter galvanized air duct, forming a closed hot air circulation system. A replaceable dehumidifying filter layer made of activated aluminum silica gel is installed in the middle of the air duct. A PT100 temperature sensor and a capacitive humidity sensor are installed on the left side of the inner wall of the fixed box 3. The sensor signal lines are connected to the control cabinet, forming a PID feedback regulation system with the temperature control module of the heat-generating pipe 202 and the frequency converter of the fan 203.

[0026] With the above structural setup, the drive motor is activated to rotate the mixing rollers 306, feeding the particleboard raw material to be dried into the processing tank 305. The heat-generating pipe 202 heats the air, and the fan 203 delivers the hot air into the fixed box 3. The hot air circulation system dehumidifies the hot and humid air before it returns. Temperature and humidity sensors monitor and automatically adjust the heat generation power and airflow in real time, while a weighing sensor displays the material weight changes in real time. The spiral agitator 307 ensures uniform heating of the material, and a safety pressure relief valve ensures safe operation of the equipment.
