Summary of the invention
Technical problem to be solved in the utility model provides the drying plant that a kind of cost is low, energy consumption is low, volume is little, and the drying effect when making it can satisfy the product high-speed extrusion can not cause that product temperature is too high yet.
The technical solution of the utility model is:
A kind of hot blast tunnel drying plant, comprise workbench, the top of workbench is provided with the hot blast tunnel, be provided with the filtering pressure reducing valve, intelligent pressure controller, the industrial heat gun that connect successively by pipeline in the workbench, the industry heat gun connects the hot blast cutter by pipeline, the hot blast cutter has upper and lower two groups, lay respectively at the upper/lower terminal of hot blast tunnel face, workbench top one side, upper and lower two groups of hot blast cutter edges of a knife point to respectively the midline position in hot blast tunnel, and a side of hot blast tunnel face hot blast cutter also is provided with guide wheel above workbench.
Be provided with the heated at constant temperature controller in the workbench.
Become 15-20 degree angles between two knife faces of hot blast cutter.
Center line between two knife faces of hot blast cutter and the midline position in hot blast tunnel are 30-35 degree angles.
Beneficial effect: by continuing to be connected with the tunnel of hot blast, compressed-air actuated wind-force and heat play drying functions to the moisture of product surface to the utility model hot blast tunnel drying plant simultaneously in the tunnel with product, and drying efficiency is higher than adopting electrothermal tube tunnel pot arch.The required energy is the alternating current of 220V * 50A and greater than the compressed air of 0.2MPa.In equipment when work,, compressed air is first by filtering pressure reducing valve and intelligent pressure controller pressure control, and again by industrial heat gun heating, hot blast is again on the hot blast cutter blows to product surface in the hot blast tunnel.
The utility model equipment volume is little, and cost is low, and energy consumption is little, reaches same drying effect, and the Drying tunnel of hot blast tunnel drying plant can be done littlely and lack 1 meter long getting final product.Plant capacity only is about the sixth of electrothermal tube constant temperature tunnel pot arch.And plant maintenance is convenient, and cost is low, only needs to change resistive heater.
The utility model equipment can be regulated actual drying effect by wind-force and the temperature of regulating hot blast.General hot blast temperature rises to 100 ℃, gets final product the normal extrusion speed of matching product, can not cause that product temperature is too high, scorches equipment and the frock of subsequent handling.
Electric heating oven dry with common changes hot-air seasoning into, has greatly improved drying efficiency.
Install intelligent pressure controller additional, can carry out moment monitoring to compressed air pressure, anti-error protection.
Thin narrow long and narrow Tunnel Design has prevented the loss of hot blast effectively, has increased the action time of hot blast, has improved the utilization rate of hot blast, has improved the drying effect of product.
Adopt the hot-blast outlet of cutter type structure, it is poor to make hot blast form certain pressure, can increase the speed that hot blast blows out, and the hot blast blow-off direction is opposite with the product direction of advance, can greatly improve the relative velocity of hot blast and product.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of hot blast tunnel drying plant, comprise workbench 9, the top of workbench 9 is provided with hot blast tunnel 8, be provided with the filtering pressure reducing valve 1 that connects successively by pipeline 3 in the workbench 9, intelligent pressure controller 2, industry heat gun 4, industry heat gun 4 connects hot blast cutter 10 by pipeline 6, on described hot blast cutter 10 has, lower two groups, lay respectively at the upper of 8 mouthful of one side in workbench hot blast tunnel, 9 top, lower two ends, on, lower two groups of hot blast cutter 10 edges of a knife point to respectively the midline position in hot blast tunnel 8, and a side of the 8 mouthfuls of hot blast cuttves 10 in hot blast tunnel also is provided with guide wheel 11 above workbench 9.
Be provided with heated at constant temperature controller 5 in the workbench 9.
