Description
Technical field
The utility model relates to wood-based plate laboratory specialty instrument, apparatus field, is specially a kind of drying equipment that relates to quick, the even dried fibres in fiberboard laboratory.
Background technology
The research and development laboratory of medium density fibre board (MDF) fiber moisture after applying glue when being made brassboard generally all is greater than 30%, and the fiber moisture that pressing plate requires is between 8%-10%, this just need to carry out drying to fiber, and require to complete fast to reduce adhesive and produce precuring when drying in dry run, lose bonding property.At present, in the fiberboard industry, never find a kind of not only easy but also quick, even, accurate drying means of control automatically of realization, had a strong impact on the new product of fiberboard industry, the R&D work of new technology.
The utility model content
The purpose of this utility model is exactly for above-mentioned defect, and a kind of simple in structure, reasonable in design, easy to operate, drying fast automatic small-sized fibre dryer in medium density fibre board (MDF) laboratory fast is provided.
The technical solution of the utility model is: comprise blower fan and cyclone separator; Described blower fan is provided with hot blast import, cold wind import and mixed export; Connect heat exchanger and hot air control valve in described hot blast import, connect cold air pipeline and cold air control valve in described cold wind import, described mixed export connects cyclone separator by fibre conveying channel; The feed opening of described cyclone separator is connected with the cold air pipeline by baiting valve; The feed opening of described cyclone is provided with online tester for water ratio, and described hot air control valve, cold air control valve and online tester for water ratio all are connected with control system.Principle of the present utility model is: will need dry fiber and cold air, the hot-air that heat exchanger produces is together sucked by blower fan, in fibre conveying channel, the moisture in fiber is evaporated, utilize cyclone separator that fiber is separated with air, the infrared ray tester for water ratio carries out continuous on-line detection to fiber, and result is input to control system, control system can be carried out analysis-by-synthesis to detected value and target setting value, then to cold, the executing agency of hot-air air intake valve sends instruction, automatically regulate the aperture of two valves, reach the purpose of regulating system baking temperature, until fiber drying is arrived to the target moisture content.
Such scheme also further comprises:
Described blower fan is centrifugal fan.
Described baiting valve is star-like baiting valve.
Described online tester for water ratio is the infrared ray tester for water ratio.
The feed opening of described cyclone separator is provided with reversible deflector.
Compared with prior art, the utlity model has following advantage:
1. low temperature is quick: for the fiber after applying glue, adopt lower temperature to carry out drying, whole dry run is in one minute, and baking temperature is curing temperature required far below adhesive, has reduced to greatest extent the precuring of adhesive.
2. uniformity: this drying machine is to carry out fiber drying under blower fan carries out the state of strength conveying, in process, fiber, in suspended state, utilizes wind-force that the fiber of conglomeration is dispelled, and hot-air and fiber are fully merged, moisture evenly evaporates, and reaches all fibres moisture content uniformity.
3. automatically control: in this drying machine work, fully adopt automatically and control, by the infrared ray tester for water ratio, fiber is carried out to online instant the detection, automatic control system is processed determination data according to the desired value of setting in advance, analysis and then cold to controlling, the executing agency of hot-air air intake valve sends instruction, automatically regulate the aperture of two valves, reach the purpose of regulating system baking temperature, autostop after system can (change the flow direction of fiber) 30 seconds by fiber collecting automatically in specified containers by the reversible deflector of cyclone separator feed opening when moisture content reaches requirement.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
In figure: 1, heat exchanger, 2, blower fan, 3, cyclone separator, 4, fibre conveying channel, 5, star-like baiting valve, 6, online tester for water ratio, 7, the cold air control valve, 8, hot air control valve, 9, reversible deflector, 10, the cold air pipeline.
The specific embodiment
