At present, the drying of the fiber preparation section of the fiber board production line is generally carried out by adopting first-level flashThe emergency drier comprises a drying fan, a drying pipeline, an expansion joint, a safe explosion-proof disc, a discharging rotary valve and 1-2 drying cyclone separator devices. The flash type dryer has the main function of quickly drying wet wood fibers (with the water content of 85-90%) coated with glue to dry fibers with the water content of only 8-15% so as to be beneficial to the use of a subsequent paving, forming and hot-pressing working section; wherein the temperature of the tail gas outlet of the drying cyclone separator is 50-55 ℃, and the emission concentration of the tail gas particulate matters is 50-175 mg/m³The formaldehyde emission concentration is 5 mg-15 mg/m³The blackness of the flue gas is less than or equal to 1, and the water content is less than or equal to 0.1kg/m³And the air volume is large and reaches 10-70 ten thousand Nm³H, pressure is about 3500-5000Pa, and wind speed is 8-25 m/s; and tail gas generated by the drying cyclone separator in the fiber board industry at the present stage is directly discharged to the air after being dedusted by a water film, and the tail gas of the drying cyclone separator at the temperature of 50-55 ℃ is not further utilized.

In the prior art, plant fibers are soaked in an adhesive to enable the adhesive to penetrate between the fibers, the high-density fiberboard is prepared by spraying the adhesive again after drying, but the adhesive with the density of 0.88g/cm3 is needed, the price of the adhesive is high, the process is complex, the fibers are soaked, taken out and dried, then dried for a long time again, and then sprayed with the adhesive again, the production process is poor in continuity degree, low in production efficiency, low in static bending strength and elastic modulus of the board, high in water absorption thickness expansion rate of 11.5%, and easy to expand in the later period;

The upper position of the trolley conveyor 1 is a fiber receiving conveying section, as shown in fig. 1, after the conveying and feeding of the trolley conveyor 1 below is finished, the trolley conveyor 1 returns to a recovery trolley 11 section of an initial section, the opening of the trolley 11 of the conveying section is upward, the trolleys of the recovery section, namely the trolleys 11 below the trolley conveyor 1 are hung upside down on a track 14 to move, the trolley conveyor 1 is driven by a driving roller 10, so that a gear chain driving all the trolleys 11 can drive the trolley conveyor 1 to move under power, the initial section of the trolley conveyor 1 is the leftmost end of the upper half part in fig. 1, namely, the position right under a glue dipping air door 22 right below a raw material separator 2, two sections of a plurality of trolleys 11 of the trolley conveyor 1 need to be completely immersed in a glue bath 13, and one section between two sections of the trolley conveyors 1 at the glue dipping position is lifted above the glue bath 13, at least two hydraulic machines 3 are arranged above a track 14 of the trolley conveyor 1, the hydraulic machines 3 are suspended right above the trolley 11 through a bearing vehicle 32, a pressure plate 31 of each hydraulic machine 3 is pressed against the top opening of the trolley 11 and lifted and retracted, the bearing vehicle 32 is suspended on a press track 33, the moving speeds of the press track 33 and the track 14 are the same, when the trolley 11 moves on the track 14, the pressure plate 31 of each hydraulic machine 3 can move forwards and press along with the speed of the trolley 11 to press the impregnated fibers in the trolley 11, so that the gas in the fibers is extruded by the adhesive and discharged out of fiber gaps, a middle section spray head 15 is additionally arranged between the two hydraulic machines 3 and used for spraying the adhesive on the fibers in the trolley 11 again after extruding the air and the adhesive, and all the adhesive absorbed when the fibers are rebounded and expanded after being extruded, the air in the fiber is the most main factor with low physical mechanical property, the hydraulic machines 3 of the device are two, namely the fiber in the trolley 11 is extruded twice, and the adhesive solution is uniformly sprayed between the two extrusion operations, so that the fiber can breathe twice above the rubber pool 13, each time the hydraulic machine 3 extrudes the impregnated fiber to exhaust the air in the fiber as much as possible, the fiber is extruded twice, the fiber is sucked to contain the adhesive when the fiber is expanded twice, after the second extrusion, the peripheral adhesive spraying head 282 sprays the adhesive on the fiber, and simultaneously the fiber which is not rebounded in the extrusion state is directly sent into the rubber pool 13 along with the trolley 11 to be impregnated completely in an immersion manner, the adhesive is ensured to penetrate into the fiber more deeply;

the trolley 11 at the tail end of the trolley conveyor 1 continuously moves forwards, the opening of the trolley 11 is turned downwards, the dipped fibers are turned over and fall into the dipped fiber frame 5, some of the dipped fibers fall onto the inclined net conveyor 51, the inclined net conveyor 51 is a conveyor belt conveyor, the scattered dipped fibers are conveniently conveyed into the dipped fiber frame 5 again, the dipped fibers are ensured not to be missed and not to fall, and the fibers dipped with the adhesive are the dipped fibers;

the bottom and the side wall of the trolley 1 are both of firm mesh structures, so that an adhesive can freely enter and exit the inside of the trolley 11, the fiber infiltration and permeation are facilitated, and the redundant adhesive can be smoothly discharged, the aperture of the mesh of the trolley 11 is not more than six times of the diameter of the cross section of the fiber, and the aperture of the rectangular mesh frame of the trolley 11 is less than one fifth of the length of the fiber, so that the fiber is prevented from scattering and separating to the outside of the trolley 11;

the feed separator 2 is a cyclone separator,

the above is a structure of a gumming device for fibers, the fibers need to be added with additives, such as a curing agent, a waterproofing agent, mildew-proof particles, flame-retardant particles and paraffin particles, for increasing various performances of a finally manufactured plate, some additives are liquid particles, the liquid additives need to be stirred and mixed uniformly, the solid particles need to be mixed uniformly, because the operation of stirring and mixing the gummed fibers and the solid particles uniformly is very difficult, basically, the fibers cannot be completely mixed uniformly and adhered tightly, and are easy to loosen, so that the additives are at the bottom of a stirrer, and the fibers are at the top of the stirrer, so that the fibers are completely separated and layered;

the additive of the system is divided into two steps, liquid curing agent and waterproof agent are mixed at the bottom of a glue dipping fiber frame 5 which is just finished by glue dipping, glue dipping fibers pass through a glue extruding conveyor 52 at the bottom of the glue dipping fiber frame 5 and can extrude redundant adhesive on the surfaces of the fibers, then the glue feeding fibers are continuously extruded to a flow guiding extrusion mechanism 53 through a spiral conveyor of the glue extruding conveyor 52, the flow guiding extrusion mechanism 53 can control the flow of the glue dipping fibers in a telescopic mode, as shown in figure 4, the flow guiding extrusion mechanism 53 moves leftwards, the flow is increased, the flow is reduced rightwards, the glue dipping fibers move leftwards and can be extruded by an extrusion cone 55, the extrusion cone is a cone with a small outlet end and a large feed inlet, the glue dipping fibers can be conveniently extruded, the redundant adhesive attached to the surfaces of the fibers can be extruded and flows away through a glue outlet groove 56 for collection, then pouring the fibers into a glue pool 13 to avoid waste, arranging a filter screen between an extrusion cone 55 and a glue outlet groove 56, so that the fibers cannot flow out, and after the dipped fibers pass through the extrusion cone 55, the fibers are left in a glue extrusion conveyor 52 to enter a flow guide extrusion mechanism 53 to limit the flow of the dipped fibers, so that the flow rate of the fibers is reduced, the glue extrusion is cleaner, and the situation that redundant adhesives are attached to the outside of the dipped fibers is avoided, but the adhesives immersed in the fibers cannot flow out without being extruded by a press, so that the dipped fibers are filled with the adhesives and only less adhesives are on the surfaces, at the moment, a curing agent and a waterproof agent are sprayed through a curing agent nozzle 57, so that the curing agent and the waterproof agent are uniformly attached to the surfaces of the dipped fibers, only the curing agent and the waterproof agent are attached to the surfaces of the dipped fibers, and then the dipped fibers with a thin layer of the curing agent and the waterproof agent attached to the surfaces slowly enter a dry dipping conveyor 54 through a degumming conveyor 54 to form hot air The glue fiber drying pipe 61 is used for rapidly drying the dipped fibers, the adhesive, the curing agent and the waterproof agent are solidified and dried up and are integrated with the fibers, then the dipped fibers enter the dipped fiber separator 6 through the glue fiber drying pipe 61, the qualified dipped fibers sprayed with the curing agent and the waterproof agent are separated and discharged by the dipped fiber separator 6, the dry fiber winnowing machine 26 on the air pipe 62 is used for screening out the dipped fibers with proper particle size and weight, the dipped fibers enter the next process, and unqualified fibers are collected and post-processed in a centralized manner;

the qualified dipped fibers sprayed with the curing agent and the waterproofing agent are separated by the dry fiber winnowing machine 26 of the dipped fiber separator 6 and enter the next process, and the next process needs to be uniformly mixed with the mildew-proof particles and the flame-retardant particles for increasing the chemical properties of the formed fiber board, and the particles are difficult to be mixed with the fibers, so that the particles need to be treated in advance.

The mildew-proof particles and the flame-retardant particles are treated as follows: firstly, feeding additive particle raw materials to be mixed into a glue mixer 44, filling an adhesive into a stirrer 44, uniformly stirring and mixing the adhesive and the particle raw materials of various additives, attaching a layer of adhesive to the surface of the particle raw materials, stirring and crushing the uniformly stirred particle raw materials again by a crusher 45, adding a combination of a screw conveyor and a high-speed crushing cutter at the bottom of the crusher, mixing the uniformly stirred and more finely crushed particle raw materials with the adhesive, then feeding the mixture into a pipeline of compressed air or steam, feeding the heated additive particle raw materials into an exhaust pipeline of a raw material separator 2, carrying out low-temperature flash drying and conveying by exhaust, conveying the particle raw materials into the exhaust pipeline of the raw material separator 2 by a feeding and drying pipe 46 for drying, then conveying the dried and qualified additive particle raw materials into an additive separator 4 for separation, and conveying the dried and qualified additive particle raw materials by a discharging and conveying machine 43, the additive particle raw materials are conveyed into an air pipe 62 at the inlet of a fiber mixing separator 41, then the solid additive particle raw materials and the impregnated fibers attached with the curing agent and the waterproof agent are uniformly mixed through the fiber mixing separator 41, and then the subsequent production process can be carried out, so that the device can well carry out the conventional processes of subsequent compression molding, forming, curing and the like, the additive particle raw materials are impregnated and are more easily attached to the fibers, and the additive particles cannot be layered and superposed, so that the additive is more uniformly mixed;

the device is subjected to the measures of over-dry fiber spraying adhesive, gum dipping, draining, squeezing, adhesive spraying, secondary gum dipping, draining, degumming, curing agent adding, waterproof agent adding, fiber drying and particle material applying, so that the fiber can be fully soaked in repeated expansion breathing, air is discharged by breathing of the fiber to permeate the adhesive, the proportion of the adhesive can be increased, air is discharged more thoroughly, the formed medium-density fiberboard is more compact, the physical and mechanical strength is higher, and various additives and fiber raw materials are mixed more uniformly;

meanwhile, various chemical raw material additives are applied to the fibers step by step, so that the performance of various materials is improved, the time of a curing agent in glue solution is shortened, and the stability of glue solution raw materials is improved.
