Method for mixing wood fibers and adhesive

Abstract

The invention discloses a method for mixing wood fibers and an adhesive, which mainly comprises that: the wood fibers in a delivery pipe are pushed to advance through impulsion of steam, the adhesive is mixed with the wood fibers in a mixing pipe, the delivery pipe is communicated with the mixing pipe, the mixing pipe is a drying pipe, and the steam forming an inclination angle with the delivery pipe is sprayed to the wood fibers; and the wood fibers are advanced spirally, and are dried in the drying pipe, and the adhesive is more evenly mixed with the wood fibers when the wood fibers are advanced in the form. In the method for mixing the wood fibers and the adhesive, when the wood fibers and the adhesive are mixed, the wood fibers and the adhesive are dried, so the water content of the wood fibers is reduced; and the steam is sprayed into the delivery pipe by forming an angle, and the wood fibers in the delivery pipe are constantly rolled and stirred, so the mixing of the wood fibers and the adhesive is strengthened; and the obtained wood fibers have good suppression effect and the quality is improved obviously.

Description

technical field

[0001] The present invention relates to a kind of production method of wood fiber, especially a kind of mixing method of wood fiber and adhesive. Background technique

[0002] In the production process of wood fiber board, the mixing degree of wood fiber and adhesive has a great influence on the quality of wood fiber board. The current mixing method is relatively random, and the wood fiber and adhesive cannot be mixed evenly. The quality of the produced wood fiber board is poor, and The mixing bin has no drying function, the fiber moisture content is high, and it is easy to delaminate and split during the pressing process, and the scrap rate is high. SUMMARY OF THE INVENTION

[0003] The purpose of the present invention is to provide a kind of mixing method of effectively mixing wood fiber and adhesive to ensure good quality of wood fiber board in order to solve the deficiencies of the above-mentioned technology.

Examples

Embodiment 1

[0009] The mixing method of wood fiber and adhesive described in this embodiment mainly includes that wood fiber is pushed forward by the impulse of steam in the conveying pipe, the adhesive is mixed with wood fiber in the mixing pipe, the conveying pipe is connected with the mixing pipe, and the mixing pipe is a drying pipe, The wood fiber is sprayed at an inclination angle between the steam and the delivery pipe. The delivery pipe and the mixing pipe are cylindrical pipe bodies. The injection direction of the steam is at an angle of 30° with the cross section of the mixing pipe containing the injection point, and the vertical section of the mixing pipe containing the injection point. The included angle is 60°, and the effect of this angle is good, and the adhesive is pressed into the mixing tube by the pump.

Embodiment 2

[0011] In the mixing method of wood fiber and adhesive described in this embodiment, the conveying pipe and the mixing pipe are cylindrical pipe bodies, and the spraying direction of the steam forms an included angle of 60° with the cross section of the mixing pipe containing the spraying point, and the mixing pipe containing the spraying point The vertical section of the pipe is at an included angle of 30°.
