Problems solved by technology

At present, there are several problems in the hot air curing of rock wool boards: first, when the curing furnace starts or stops, it needs to follow a certain heating or cooling procedure, and it takes a relatively long time to start production; There is a problem of uneven distribution in the curing furnace, which will affect the various properties of the rock wool board; third, the heat transfer mode under the hot air curing method is from the outside to the inside, which will be accompanied by a large amount of heat loss, resulting in energy waste; Fourth, the energy source of the hot air is provided by burning coal, which will pollute the atmosphere when the coal is burned, and is an unclean energy

Embodiment 1

[0035] The curing method of this example was carried out by a conventional microwave curing apparatus. This microwave curing device is usually divided into a microwave generating area and a microwave curing area. A microwave generator is arranged in the microwave generating area, and the microwave generator may be a microwave generating device commonly used in the field. The rock wool board is cured in the microwave curing area and a platform for placing and transporting the rock wool board to be cured is provided. The platform will not react with the rock wool board to be cured during the microwave curing process and will not be affected by microwave irradiation. made of material. In order to ensure the effect of microwave irradiation, the microwave generating area is usually arranged above the microwave curing area, but this is not strictly limited.

[0036] like figure 1 As shown, the curing method of this embodiment includes:

[0037] Step 110, put the rock wool board ...

Embodiment 2

[0046] In Example 2, two microwave irradiations at intervals were used for curing, which was also implemented by the same microwave curing device as in Example 1.

[0047] like figure 2 As shown, the curing method of this embodiment includes:

[0048] Step 210, put the rock wool board to be cured on the platform in the curing area of ​​the microwave curing device, and close the door of the microwave curing device;

[0049] Step 220, starting the microwave generator of the microwave curing device, and irradiating the rock wool board once with microwaves;

[0050] Step 230, the interval is a set time period;

[0051] Step 240, start the microwave generator again, and perform secondary microwave irradiation on the rock wool board;

[0052] Step 250, stop the secondary microwave irradiation.

[0053] In an example, the specification of the rock wool board to be cured is 1200mm*600mm, the thickness is 80mm, the power of the first microwave irradiation on the rock wool board is...

Embodiment 3

[0059] The curing method of this embodiment is carried out by an improved microwave curing device. The schematic diagram of the improved microwave curing device is as follows: Figure 5 shown.

[0060] The microwave curing device in this embodiment is provided with an air circulation system, and the air circulation system may include an air circulation pipeline disposed outside the microwave curing device and an air inlet and an air outlet disposed on the cavity of the microwave curing area, so that the microwave curing The inside of the zone forms an air circulation line that communicates with the air circulation line outside the microwave curing device. In addition, the air circulation system may also include a circulation fan arranged on the air circulation pipeline, for example, it may be arranged at one end close to the air outlet. cycle. At the same time, a transformer area is arranged below the microwave curing area, but the location of the transformer area is not limit...

Abstract

A rock wool board microwave solidification method comprises the following steps: putting a rock wool board to be solidified in a platform in the solidification area of a microwave solidification apparatus, and closing the door of the microwave solidification apparatus; starting the microwave generator of the microwave solidification apparatus, and carrying out primary microwave irradiation on the rock wool board; powering off the microwave generator for a preset time quantum; restarting the microwave generator, and carrying out secondary microwave irradiation on the rock wool board; stopping the secondary microwave irradiation; and taking out the rock wool board to complete solidification. The solidification method disclosed in the invention has the advantages of short time, low energy consumption, clean energy, uniform solidification distribution, and substantial improvement of the mechanical performances of a product.

Description

technical field [0001] The present application relates to the production technology of rock wool board, in particular to a solidification method of rock wool board and a microwave solidification device for implementing the microwave solidification method. Background technique [0002] The existing domestic rock wool board production, such as rock wool board production, is basically hot air curing of the formed rock wool board, and the production operating temperature of the curing furnace is generally controlled at 200-230 °C. With the development of society, people have higher and higher requirements for the improvement of production efficiency and environmental protection. At present, there are several problems in the hot air curing of rock wool boards: first, when the curing furnace is started or stopped, it needs to be carried out according to a certain heating or cooling procedure, and it takes a relatively long time to produce; There is a problem of uneven distributio...
