1. energy-saving programs

    Existing injection molding machine is equipped with systems for plastic dehumidifying dryer, electric heating mode to provide heat, air discharged from the outlet insulation injection molding machine drying drums carry a certain amount of heat, when this part of the heat directly into the workshop on the one hand increases the injection molding machine workshop content of dust in the air and affect the operation of the health of workers, on the other hand will increase energy consumption and increase the financial burden on businesses.

Has some water, hot air from the dust discharge 4 through the pipe into the dust circulating hot air dehumidifying device 3 by its handle 3, a portion of the heat source after the next adjustment turbine 6 to power a hot gas, such that a flow cycle, after processing proceeds 2,2 6 by plastic barrel and the heat of the hot gas entering the further heat treatment; and another portion of hot air heated gas through 5 are 2, 4 which can adjust the temperature of the air flow rate within 6 to ensure that the actual 4 correspond to the set temperature. When the temperature inside the 4 lower than the set, 5 to 6 signals, increase speed to increase the output amount of wind at 6 driving action, enter 4, after two high temperature air increases, the temperature rise inside the 4, when the inner 4 a higher temperature than the set temperature is high, the signals 5 to 6, 6 to reduce the speed and reduce the output of wind, thus reducing the gas temperature entering the 4, 4 temperature is lowered.

2. Economic Benefit Analysis

    Technical Data Features

    (1) System power saving 15% to 35%, saving more than 90% of the dryer;

    (2) high temperature 270 ℃ ~ 280 ℃, low temperature -70 ℃;

    (3) production workshop temperature drop of up to 3 ° ~ 8 °, the working environment has greatly improved;

    (4) CO2 emissions than conventional reduced by 45% to 50% and no SO2, fly ash, slag, NOx emissions low;

    (5) Tensile strength ≥0.02MPa;

    (6) corrosion resistance, aging, waterproof, anti-oil, anti-oil pollution, environmental protection, pollution-free;

    (7) Easy to install, good service, toughness, flexible bandage;

    (8) for different temperatures, the shape of the injection molding machine.


    Problems and Suggestions Existing waste heat utilization

    Problems below.

    (1) of the injection molding machine plastic processing enterprises throughout the country, but the equipment skill levels, a lot of business equipment needs further transformation;

    (2) ban plastic industry voices, but in the rural market is still widely used plastic products, cutting costs has become a top priority for enterprise development;

    (3) Since the channels of information dissemination and corporate lack of funds has greatly restricted the lot to promote this technology, many enterprises lack advanced mechanism of the injection molding machine injection molding machine injection molding machine energy-saving technologies and clean development mechanism, advanced injection molding machine technology service providers there is no way to understand the situation of the enterprise;

    (4) high-temperature waste heat utilization technology after years of development is now more mature, successful cases also showed its economic benefits, but the huge potential of the low-temperature waste heat utilization needs further development.

    Corresponding recommendations are described below.

    (1) manufacturers of injection molding machines to do the management and use "proper use, scientific management, careful maintenance, regular maintenance, reasonable lubrication, planned maintenance, improve equipment availability, the equipment in good condition;

    (2) pollution energy consumption is a top priority, as one of the main thermal energy-saving, more active policies should be introduced, given the appropriate financial support, and guide enterprises to play an active role in industry waste heat recovery;

    (3) to carry out injection molding machine waste heat resources research and gather relevant advanced injection molding machine technology, management and strengthen information dissemination and other cases, strengthen the research in low-temperature waste heat utilization technology, promoting the application of heat technology.

    (4) Recommendation injection molding machine waste heat utilization potential of the enterprise, considering the system as far as possible, the overall improvement, and focus on the refinement of the use of automatic control systems.
