Description
The utility model belongs to the process equipment of plywood single board.
The manufacturing of glued board is to improve one of effective measures of wood raising timber utilization rate.The plywood single board dry run is the process procedure big, that yield poorly that consumes energy in the plywood production.Traditional plywood single board drying machine adopts the Convective Heating method, utilize the steam that boiler takes place to add hot-air and material as thermal source through heat exchange, thereby equipment is huge, and the thermal efficiency is low, and one-time investment is big, and causes environmental pollution.At present domestic and international drum-type plywood single board drying machine, it is many to expend metal, about 45 meters of complete machine length, about 150 tons of weight, and the thermal efficiency has only about 33%, be 4～6 minutes the drying time of veneer.The American drum-type veneer dryer made of Taiwan and for example, 41 meters of model 4VDJ-45-14H total lengths, 28 meters of the thermals treatment zone, 6 meters of cooling zones are veneer drying time of 1.5mm to be about 6.5 minutes for thickness.The American chain-belt conveyer veneer drier model that make in Taiwan is 3VDC-27-16/2C, 43 meters of total lengths, and the thermal efficiency is 30%.Do not see by retrieval the technology identical with the utility model arranged.
The purpose of this utility model provides a kind of compact conformation, the production efficiency height, and reduced investment, energy savings reduces the plywood veneer dryer that pollutes.
Main points of the present utility model are that the high temperature directed radiation heater that adopts many groups to contrast layout up and down is a thermal source, to veneer and cylinder heating.Another feature of the present utility model is to adopt the air draught type dehumidification system that moisture evaporated in the dry run is discharged.The veneer transmission system adopts short chain driving drum conveying device in the utility model, and cylinder floating support on it, bottom roll are fixed bearing, and two cylinder gap can be regulated, to adapt to the drying processing of different-thickness plywood single board.Skeleton of the present utility model is the short opening fuselage of length.
Fig. 1 is high temperature directed radiation heating plywood single board drier structure schematic diagram.Fig. 2 is a cylinder drive mechanism schematic diagram.Fig. 3 is the dehumidification system schematic diagram.3-skeleton among the figure, 4-heater, 5-spiral shell select, 6-nut, 7-air-suction trunk, the 8-suspended hood, 9-adjusts tile, 62-graphite bearing, 63-alignment pin, the 64-key, 65-gear, 66-opening graphite axle bush, 67-graphite tile support, 68-graphite steady pin, 69-sprocket wheel, 70-key, 71-bearing block hold-down screw, the 72-hold-doun nut, 73-pad, 74-bottom roll, the last cylinder of 75-, the 85-threeway, 86,87 ,-control valve.
As shown in the figure, the high temperature directed radiation heats its structure of plywood single board drying machine by transmission system, heating system, and several parts such as dehumidification system and skeleton and switch board are formed.Transmission system of the present utility model is to use stepless speed-regulating motor to be used as power, and drives bottom roll 74 again through belt drive system driven gear 65 and rotates, and sprocket wheel 69 rotates the bottom roll that drives each series cylinder respectively through short chain simultaneously.Fig. 2 represents the cylinder drive mechanism.The characteristics of the utility model cylinder transmission system are that bottom roll 74 is fixing, and last cylinder 75 is floating type.Look the plywood single board thickness requirement of processing, the adjustable gaps between the up-down roller is adjusted by means of set adjustment tile 9 between opening graphite axle bush 66 and the graphite tile support 67.Heating system of the present utility model, the leading portion high temperature thermal treatment zone at the plywood single board heat drying, the high temperature directed radiation infrared heater that adopts many group contrast formulas to arrange, warm carborundum plate infrared heater in many groups of the middle temperature thermal treatment zone employing contrast formula layout in mid-term and later stage, two kinds of heaters all can carry out the adjusting of radiation length by spiral shell select 5 and nut 6.As shown in Figure 1, heater and cylinder adopt alternate layout, and heater had both heated plywood single board, heat up-down roller again, and up-down roller heats it again in the force feed plywood single board, makes water evaporates, play straightening and thermocompression forming effect simultaneously.In the high temperature thermal treatment zone, the veneer quick heating has shortened the veneer drying dewatering time greatly, for the veneer of 1.5mm specification, uses the utility model to be about 2.5 minutes arid cycle.Drying property is good, and heat loss is little, and the complete machine thermal efficiency is about 60%.Dehumidification system of the present utility model is to be used as power with air blast, by the air channel, and control valve 86,87, threeway 85, the air draught type dehumidification system that suspended hood 8 and air-suction trunk 7 etc. are formed.Leading portion air draught type hydrofuge is for forcing mobile hydrofuge.As shown in Figure 3, by the moisture that the suspended hood 8 and the below air-suction trunk 7 of top are extracted out, control valve 86 places after threeway 85 converge, and enter blower fan and are discharged from.Change the aperture of control valve 86, can change the working condition of blower fan, to adapt to the dry run of different humidity just and different thicknesss of slab.Be provided with control valve 87 in the air channel of suspended hood 8 on being communicated with, the variation of its aperture size is in order to change hydrofuge air draught burden apportionment up and down.In back segment sub-cooled district, adopt free convection air draught cooling dome, with energy savings and minimizing heat loss.Skeleton 3 of the present utility model is the load parts of this machine, by angle steel, and the frame-type segmentation package assembly that section bars such as channel-section steel are formed, compact light and handy, installation and transportation are convenient.Be mainly the conduction heating of radiation heating and cylinder in addition owing to heating system, thereby adopt open rack construction, save the heat-insulating material that Convective Heating type drying machine is arranged, alleviated body weight, saved material and fund.Switch board of the present utility model is general electrical control part, by temperature controller, and thermocouple, jettron, buncher control box, relay, compositions such as cable and metal cabinet.
The utility model utilizes the dry dynamic design method of unstable state, adopted high temperature directed radiation infrared heater, arranged that up and down directed radiation carries out the high strength drying to plank, cylinder is accepted radiant heat as auxiliary thermal source, veneer is played heat (pressure) styling, improved quality.Heating and the hydrofuge design optimized, with open segmentation type skeleton, make the complete machine floor space little, in light weight, thermal efficiency height, arid cycle is short, and fitting operation is easy to maintenance, the productivity ratio height, energy savings, having reduced the pollution to environment, can be widely used in the Wooden veneer processing in various fields such as plywood production and match, technology, musical instrument, is desirable veneer drying equipment.
