Abstract
The present invention discloses woody fiber board producing process. The production process includes the following steps: 1. weighing fiber material and grinding in a grinder; 2. conveying the initially separated ground material to drying room through hot blast circulating pipeline; 3. drying material and spraying atomized glue to the dried material in the outlet of the drying room with glue pump and nozzle to spray compressed air and glue liquid; 4. separating the glued material with a cyclonic separator and feeding to the material bin; and 5. spreading the material and pressing to produce the woody fiber board. The present invention has homogeneous gluing, no sticking to the pipeline, high material utilization rate, high product quality, high production efficiency and low production cost.
Description
Technical field:
The present invention relates to operation, particularly a kind of glue-applying technique is reasonable, can guarantee product quality, can improve the method for the production wood fibre board of service life of equipment again.
Background technology:
At present, the method for production wood fibre board, generally the processing step of Cai Yonging is; 1. the raw material of former feed bin is delivered to and put into behind the weighing in the level-sensing device that grinding machine grinds and preliminary sorting; The material that 2. will grind also preliminary sorting is delivered into hothouse through the cycling hot feed channel, carries out drying and handle after the feeding mouth place of hothouse adds glue; 3. dried material with the cyclone separator sorting after screening washer and pipeline are sent into feed bin concentrates; 4. the material in the feed bin is carried through pipeline with air-introduced machine and gone to mat formation, and be pressed into fiberboard.The method of this traditional production wood fibre board, because what adopt is to carry out applying glue before the fibre material drying, not only applying glue is inhomogeneous, influence product quality, but also the sticking plugging road of glue can take place, influence is produced and the minimizing service life of equipment.
Summary of the invention:
It is evenly reasonable to the purpose of this invention is to provide a kind of not only applying glue, guarantees product quality and not sticking plugging road, helps producing the method for the production wood fibre board of improving with equipment life.
Technical scheme of the present invention is finished as follows, includes in the method for this production wood fibre board 1. the raw fibre sheet to be delivered to put into grinding machine in the level-sensing device behind the weighing and grind; 2. grind after preliminary sorting is sent material into the hot gas cycle pipeline and be delivered into hothouse, it is characterized in that: 3. at the discharging opening place of hothouse with shower nozzle to the applying glue that atomizes of dried material, the atomizing applying glue is the nozzle place that glue is thrown into shower nozzle with the glue pump, simultaneously compressed air is introduced nozzle cavity, gauge tap under certain pressure, open make compressed air and glue together in the nozzle of shower nozzle atomizing spray to material; 4. the material behind the dry spray glue is sent into feed bin after with the cyclone separator sorting; 5. the material of concentrating in the feed bin is sent to through pipeline with air-introduced machine and mated formation, be pressed into wood fibre board then.Above-mentioned spray-bonding craft also can make two bites at a cherry at hothouse discharging opening and cyclone separator discharging opening respectively, and resin added everywhere is controlled at 40%-60% respectively.
The technology of the dry after dryer sizing of this employing, it is even to have an applying glue, and sticking plugging road helps improving stock utilization, improves product quality and production efficiency, and reduces production costs.
Description of drawings:
Fig. 1 is a process chart of the present invention,
Fig. 2 is an applying glue shower nozzle internal structure schematic diagram of the present invention.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing: the equipment that the present invention uses all is existing equipment except that shower nozzle 7, among the figure, and 1, the combustion chamber, 2, former feed bin, 3, grinding machine, 4, level-sensing device, 5, the hot gas cycle pipeline, 6, hothouse, 7, shower nozzle, 8, cyclone separator, 9, hothouse, 10, screening washer, 11, the glue pump, 12, feed bin, 13, air compressor, 14, air-introduced machine, 15, mat formation 16, compressed air inlet pipe, 17, the glue pipe.
Concrete process is:
1. the raw fibre sheets in the former feed bin 2 are delivered to and put into grinding machine behind the weighings in the level-sensing device 4 and grind; 2. grind after preliminary sorting is sent material into hot gas cycle pipeline 5 and be delivered into hothouse 6, the thermal source of hothouse and hot gas cycle pipeline is from combustion chamber 1; 3. at the discharging opening place of hothouse with the applying glue that atomizes of 7 pairs of dried materials of shower nozzle, the atomizing applying glue is the nozzle place that glue is thrown into shower nozzle through glue pipe 17 with glue pump 11, with air compressor 13 compressed air is introduced nozzle cavity through air inlet pipe 16 simultaneously, be controlled under the certain pressure and open nozzle switch, glue is atomized with compressed air spray to material; 4. the material behind the dry spray glue is sent into feed bin after with the cyclone separator sorting; 5. material is sent to through pipeline with air-introduced machine 14 according to the requirement of product and mated formation, be pressed into wood fibre board then.Above-mentioned spray-bonding craft also can make two bites at a cherry at hothouse discharging opening and cyclone separator discharging opening respectively, and resin added everywhere is controlled at 40% and 60% respectively.
Claims (2)
1, the method for a kind of production wood fibre board includes in the method for this production wood fibre board 1. the raw fibre sheet to be delivered to and puts into grinding machine in the level-sensing device behind the weighing and grind; 2. grind after preliminary sorting is sent material into the hot gas cycle pipeline and be delivered into hothouse, it is characterized in that: 3. at the discharging opening place of hothouse with shower nozzle to the applying glue that atomizes of dried material, the atomizing applying glue is the nozzle place that glue is thrown into shower nozzle with the glue pump, simultaneously compressed air is introduced nozzle cavity, gauge tap under certain pressure, open make compressed air and glue together in the nozzle of shower nozzle atomizing spray to material; 4. the material behind the dry spray glue is sent into feed bin after with the cyclone separator sorting; 5. the material of concentrating in the feed bin is sent to through pipeline with air-introduced machine and mated formation, be pressed into wood fibre board then.
