Technical Field

The invention relates to the technical field of paper pulp molding production equipment, and particularly discloses a heat-setting heating plate for the paper pulp molding production equipment.

Background

The paper pulp molding products include paper tableware, industrial product packages and the like, heat setting is required in the production process of the products, two conventional heating modes of heat setting are adopted, one mode is that a boiler is used for heating (high-temperature steam) heat conduction oil (namely heat medium), then energy is transferred to a coil type heating plate through a conveying pipeline, and the heat conduction oil (heat medium) enters the boiler again for heating after being cooled in a closed circulation mode. The energy of the heating plate is tightly combined with the mould through the plate body, so that the heat energy of the heating plate is conducted to the mould; the other is heating by an electric heating pipe, electric heating pipes are arranged in the heating plate, and the anode and the cathode are connected with electricity to heat the heating plate.

The boiler heating mode has high danger and high energy consumption, and the heat transmitted through the pipeline is lost more in the transmission process, thereby wasting resources; the electric heating tube has high heating energy consumption and much heat loss.

Disclosure of Invention

The invention aims to: the heat setting heating plate for the pulp molding production equipment has the advantages of good safety, low energy consumption and full utilization of heat.

The technical scheme adopted by the invention is as follows:

a heat setting hot plate for paper pulp molding production equipment comprises a metal hot plate, an upper plate, a lower plate and a far infrared nano microcrystalline glass electric heating piece, wherein a cavity for arranging the far infrared nano microcrystalline glass electric heating piece is formed between the upper plate and the lower plate.

Furthermore, the far infrared nanometer microcrystalline glass electric heating pieces are provided with a plurality of blocks and are connected with a power supply through conductors.

Furthermore, a plurality of far infrared nanometer microcrystalline glass electric heating pieces are connected in parallel.

Furthermore, an elastic insulating heat-resistant high-temperature-resistant material layer is arranged between the lower plate in the cavity and the far infrared nano microcrystalline glass electric heating sheet.

Furthermore, a layer of rock wool is arranged between the lower plate in the cavity and the far infrared nano microcrystalline glass electric heating sheet.

Furthermore, a layer of elastic heat-conducting high-temperature-resistant material is arranged between the upper plate in the cavity and the far infrared nano microcrystalline glass electric heating sheet.

Furthermore, a layer of metal sponge plate or metal foam plate is arranged between the upper plate in the cavity and the far infrared nano microcrystalline glass electric heating sheet.

Further, the upper plate and the lower plate are detachably connected.

In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:

1. the far infrared nanometer microcrystalline glass electric heating piece is adopted to replace a boiler to supply heat, and the heating mode of heat conduction of a heating medium is safer.

2. The far infrared nanometer microcrystalline glass electric heating piece has wider heating area relative to the heat conduction of the coil pipe, and the heating plate can heat up more quickly.

3. The far infrared nanometer microcrystalline glass electric heating piece has less heat loss, heating is carried out inside the heating plate, no loss in the pipeline conveying process exists, the electric-heat conversion rate is high, and resources are fully utilized.

4. The far infrared nanometer microcrystalline glass electric heating pieces have long service life, and the far infrared nanometer microcrystalline glass electric heating pieces are connected in parallel, so that other normal work cannot be influenced even if a certain electric heating plate is damaged.

5. The far infrared nanometer microcrystalline glass electric heating piece is adopted to heat, so that the energy consumption is greatly reduced compared with that of a boiler or an electric heating tube, and the power consumption requirement is reduced.
