Summary of the invention
The purpose of this utility model be to overcome above-mentioned shortcoming and provide a kind of plastic dryer it can effectively save electric energy, shorten the baking material time, reduce the workshop temperature.
Its purpose can realize by following scheme: this plastic dryer comprises hopper, warm-air pipe, air exhauster, the air outlet of air exhauster connects the air inlet of warm-air pipe, the air outlet of warm-air pipe connects the air inlet of hopper, hopper also is provided with air outlet, it is characterized in that: the sidewall of hopper comprises internal layer bucket wall, outer bucket wall, is filled with insulation material between internal layer bucket wall and outer bucket wall.
Be preferably, the air outlet of hopper also is connected with the recovery airduct, and the air outlet that reclaims airduct is communicated to the air inlet of air exhauster.
Be more preferably, between the air inlet of air outlet that reclaims airduct and air exhauster, also be provided with filtering chamber, be provided with air filter in the filtering chamber; The filtering chamber bottom is provided with dust hopper, and dust hopper is positioned at the air filter below.
Air exhauster and filtering chamber fixedly are made as one, and filtering chamber is arranged on a side of air exhauster, and the air inlet of air exhauster faces the cavity of air filter central authorities, and the air outlet that reclaims airduct directly is communicated with the annular chamber of air filter periphery.
At the opposite side of air exhauster, also be provided with the air intake aperture with respect to filtering chamber.
The top cover of hopper comprises internal layer capping, outer capping, is filled with insulation material between internal layer capping and outer capping.
The utlity model has following advantage and effect:
1, the sidewall of the utility model hopper comprises internal layer bucket wall, outer bucket wall, between internal layer bucket wall and outer bucket wall, be filled with insulation material, the heat that can reduce the hot-air in the hopper so significantly by the hopper metallic walls outwards conduct, radiation, reduce thermal loss, save electric energy, shorten the baking material time, reduce the workshop temperature.Equally, the top cover of hopper also is filled with insulation material, can further reduce thermal loss, saves electric energy.
2, the air outlet of hopper also is connected with the recovery airduct, and the air outlet that reclaims airduct is communicated to the air inlet of air exhauster, can form the circulating reflux state to hot blast like this, and the hot blast waste heat can be recycled, and further saves electric energy.In the utility model, the combination of heat insulation structure and hot air circulation recovery structure can significantly improve the energy-conservation power savings of hot air circulation recovery structure, reduces the heat that is discharged into the workshop at double.
3, air exhauster and filtering chamber fixedly are made as one, and the cavity of air filter central authorities faces the air inlet of air exhauster, and the air outlet that reclaims airduct directly is communicated with the annular chamber of air filter periphery, and this design can make overall structure simply compact.
4, air filter can avoid polluting workshop condition with containing a large amount of dust and colorant micro particle filtering in the plastics, effectively keeps the air cleanliness in the factory building, and it is healthy to avoid endangering the workman.
5, owing to adopt circulating air oven dry plastics, can reduce the quantity that sucks outside air, the middle dust impurity that reduces outside air enters airduct, even there is small amount of dust impurity to enter the circulatory system, also can filter by air filter, avoid dust impurity and plastics to be mixed into plastic molding press, therefore can improve the plastic shaping product quality.
6, can effectively reduce the hopper side wall temperature, a barrel wall temperature is reduced to about 40 ℃~50 ℃, so just not have the danger of scalding the people.
