Problems solved by technology

[0003] However, due to the flammability of ordinary oriented strand board, its application in many fields is limited
Although the existing oriented strand board usually improves the flame retardancy by adding flame retardants, the process is often very complicated, or the cost is high due to the use of expensive flame retardants, and the flame retardancy cannot meet higher safety requirements

Embodiment 1

[0057] A wet flaking conveying device equipped with a flame retardant spraying device, the wet flaking conveying device includes: a belt 1, a blanking channel 3, a hollow drum 4, a screw extruder 8 and a spraying device;

[0058] The blanking channel 3 is connected with the belt 1, and the hollow drum 4 is arranged inside the blanking channel 3;

[0059] The screw extruder 8 is arranged below the blanking channel 3;

[0060] The spraying device is connected with the blanking channel 3; the spraying device includes: a flame retardant storage tank 9, a pressure nozzle 5 and a flame retardant delivery pipeline, and the pressure nozzle 5 is connected to the flame retardant storage tank 9 through the flame retardant delivery pipeline.

[0061] Such as figure 1 As shown, the pressure nozzles 5 are evenly arranged on the outer surface of the hollow cylinder 4, and 10 nozzles are arranged on each hollow cylinder. The installation angle of the pressure spray head 5 is perpendicular t...

Embodiment 2-19

[0072] Adopt the device that embodiment 1 provides, wet shaving (wet shaving specification: width 5-40mm, thickness 0.4-0.8mm, length 100-180mm) enters in the blanking channel, from the top of the blanking opening of the blanking channel and around The flame retardant solution is sprayed towards the moving wet flakes; at the same time, in the blanking channel, the flame retardant solution is sprayed on the wet flakes while breaking up the wet flakes to obtain flame retardant flakes. The spraying range of flame retardant solution spraying can cover all slices.

[0073] The disintegration speed in Examples 1-14 is 20-30r / min, and the disintegration speed in Examples 15-19 is 40-50r / min.

Abstract

The invention discloses a wet planed sheet conveying device with a flame retardant spraying device and a flame retardant spraying method. The wet planed sheet conveying device comprises a belt, discharging passage, a scattering device, a screw extruder and a spraying device, the discharging passage is connected with the belt, the scattering device is arranged inside the discharging passage, the screw extruder is arranged below the discharging passage, the spraying device is connected with a discharging port of the discharging passage and / or the scattering device and comprises a flame retardantstorage tank, a nozzle and a flame retardant conveying pipeline, and the nozzle is connected with the flame retardant storage tank through the flame retardant conveying pipeline. A flame retardant solution is sprayed to wet planed sheets moving in the discharging passage in the wet planed sheet conveying device, so that flame retardance of the wet planed sheets when being conveyed into a wet planed sheet bin is improved effectively.

Description

technical field [0001] The invention belongs to the field of wood processing and relates to a device for wood processing, in particular to a wet shaving conveying device equipped with a flame retardant spraying device and a flame retardant spraying method. Background technique [0002] Oriented strand board (OSB) is a kind of oriented structural board made of poplar, pine and other wood as raw materials, processed into shavings by special equipment, dried, glued, oriented paving, hot-pressed and other processes. The surface flakes are arranged vertically, and the core flakes are arranged horizontally. This criss-cross arrangement reorganizes the wood grain structure, completely eliminates the influence of wood internal stress on processing, and makes it have excellent processability and moisture resistance. OSB has a directional structure inside, no joints, no gaps, no cracks, good overall uniformity, and high internal bonding strength, so OSB has been widely developed in r...
