Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
As shown in figure 1, the two sides of a rotary spherical digester 1 of the fiberboard edge recovery system are provided with a steam pipeline inlet 1-1 and a pipeline outlet 1-2, the upper part of the rotary spherical digester is provided with a material inlet 1-3, the pipeline outlet 1-2 is communicated with a coarse pulp tank 2 through a pipeline, one end of a water pump 3 is communicated with the coarse pulp tank 2 through a pipeline, the other end of the water pump is communicated with an inlet of an overhead tank 4 through a pipeline, an outlet of the overhead tank 4 is connected with an inlet of a refiner 5 through a pipeline, a pulp tank 6 is communicated with an outlet of the refiner 5 through a pipeline, and a fourdrinier forming machine 7 is arranged at the downstream of the pulp tank 6 and is communicated with the pulp tank 6 through a pipeline. The above-mentioned rotary spherical digester 1 can be used for evaporating waste board edge into coarse fibre form. The refiner 5 described above may further grind the coarse fibre pulp into a fibre pulp that can be used for the production of fibreboard.
The upper part of the rotary spherical digester 1 is provided with a working platform 8, and a lifter 9 is arranged above the working platform 8. The working platform 8 can facilitate the workers to pour the waste plate edges into the rotary spherical digester 1, and the lifting machine 9 can facilitate the workers to lift the waste plate edges to the working platform 8.
The fourdrinier wire forming machine 7 comprises a flow box in front of the wire, to which the stock chest 6 is connected by means of a pipe.
As shown in fig. 2, the process flow for normally producing the fiberboard is as follows: the raw materials are subjected to chipping, hot grinding, paving, hot pressing and sawing in sequence to form finished plates, and the finished plates are put into a warehouse for sale. After the above-mentioned sawing process, waste board edges are generated, and the waste board edges are collected by workers and then sent to the rotary spherical digester 1. Due to the high temperature and high pressure environment in the rotary spherical digester 1, the waste board edges are quickly evaporated into coarse fibers, but the coarse fibers cannot be directly used in production, so the waste board edges need to sequentially pass through the coarse pulp tank 2 and the high-level tank 4 and then enter the refiner 5 for further grinding, fine fiber slurry after grinding meets the production regulations, and the fine fiber slurry is guided into the slurry tank 6 for subsequent paving. Namely, the board edge recovery system forms a cycle on the basis of the original production process, realizes the recycling of resources and reduces the production cost of the fiberboard.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected, and may communicate between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
