Description
Technical Field
The invention relates to the technical field of surface coating and drying equipment, in particular to a heat insulation plate structure and drying equipment.
Background
At present, in the surface coating drying equipment industry, the energy consumption of the drying equipment mainly comprises four parts: the coating of the workpiece 4 is dried and solidified after absorbing heat, a carrier for conveying the workpiece absorbs heat, drying equipment dissipates heat, and an inlet and an outlet ventilate and dissipate heat. The ratio of each component is: the heat absorption of the workpiece is 45%, the heat dissipation of the drying equipment is 25%, the heat absorption of the carrier 5 is 18%, and the air exchange and heat dissipation of the inlet and the outlet are 12%.
Energy consumption accounts for a ratio:
(1) absorbing heat of the workpiece: in order to dry and cure the coating on the surface of the workpiece, the workpiece with the coating enters a drying device to absorb heat and raise the temperature to the process temperature, and the coating is cured.
(2) Heat dissipation of the drying equipment: because the inside high temperature environment that belongs to of drying equipment, the outside normal atmospheric temperature environment that belongs to of drying equipment, there is the difference in temperature, so drying equipment is losing the heat in succession.
(3) The carrier absorbs heat: the fixture for bearing and conveying the workpiece absorbs certain heat because the fixture enters the drying equipment along with the workpiece.
(4) And (4) air exchange and heat dissipation at an inlet and an outlet: the workpiece enters and exits the drying equipment at any time, and cold air brought in by the workpiece and hot air brought out by the workpiece continuously exchange heat. The composition of the drying equipment is shown in figure 1.
The energy consumption of the workpiece 4 for absorbing heat is effective energy consumption, and the energy consumption of the carrier for absorbing heat and the heat dissipation of air exchange at the inlet and the outlet are ineffective energy consumption, which are influenced by various factors, are irrelevant to the patent and are not described in the patent. The heat dissipation of the drying equipment is also ineffective energy consumption, and although the loss of the energy consumption is inevitable, the aim of reducing the energy consumption can be achieved through the innovation of the structure.
At present, common drying equipment on the market is formed by splicing and assembling rock wool boards 2 which are glued and formed by hot pressing by adopting a tongue-and-groove structure. As shown in fig. 2:
drying equipment manufactured by adopting the plate structure shown in fig. 2 generally has the following components:
1) Splicing gaps 3;
2) The splicing tongue-and-groove structure coated by the iron plate 1 forms a heat transfer heat bridge from inside to outside at the iron plate. And the above 2 points can continuously radiate heat outwards when the drying equipment operates.
Therefore, the heat dissipation path of the current drying equipment mainly comprises three points:
(1) high temperature inside the equipment → rock wool → normal temperature outside the equipment;
(2) hot air → gap → normal temperature outside the equipment;
(3) high temperature inside the equipment → iron plate → normal temperature outside the equipment.
Note: the heat transfer coefficient of rock wool is: 0.036-0.041W/(M ℃);
the heat transfer coefficient of air is: 0.026-0.032W/(M ℃);
the heat transfer coefficient of the iron plate is: 80W/(M deg.C).

The embodiment of the application relates to a thermal-insulated panel structure, this thermal-insulated panel structure mainly becomes a point by three points through the radiating route of panel structure among the prior art: namely (1) high temperature inside the equipment → rock wool → normal temperature outside the equipment; finally, the comprehensive heat dissipation energy consumption of the drying equipment manufactured by the heat insulation plate structure provided by the invention is reduced to below 15% from 25%, and the heat insulation plate structure provided by the application can also be used as a heat insulation shell of other equipment, which is not limited by the application.
Fig. 3 is a schematic structural view illustrating an insulation panel structure according to some embodiments of the present application, and the insulation panel structure according to the embodiments of the present application will be described in detail with reference to fig. 3. It should be noted that the following examples are only for explaining the present application and do not constitute a limitation to the present application.
In an embodiment of the present application, as shown in fig. 3, the insulation panel structure may include: the heat insulation structure comprises a first plate 7 component, wherein the first plate 7 component comprises a plurality of first plates 7 with heat insulation functions, and the adjacent first plates 7 are formed by overlapping through a first tongue-and-groove structure 10; the second plate 8 component comprises a plurality of second plates 8 with heat insulation functions, and the adjacent second plates 8 are formed by overlapping through second tongue-and-groove structures 11; an insulation layer 9, said insulation layer 9 being arranged between the first 7 and the second 8 sheet part. Here, the first bezel structure 10 and the second bezel structure 11 are conventional overlapping structures of panels in the prior art, and the first panel 7 at the first bezel structure 10 and the second panel 8 at the second bezel structure 11 are covered with metal wrappers. The metal sheath of the embodiment is preferably made of iron sheet, but the copper sheath can be made of copper sheet without considering the cost.
By providing the insulating layer 9 between the first plate 7 component and the second plate 8 component, the heat conduction between the (2) th point and the (3) th point can be greatly reduced, that is, (2) hot gas in the equipment → gap → normal temperature outside the equipment; (3) high temperature inside the equipment → iron plate → normal temperature outside the equipment.
In some embodiments, the first bezel structure 10 and the second bezel structure 11 are arranged in an offset manner. The tongue-and-groove structure arranged in a staggered way can greatly reduce the heat dissipation of a heat bridge formed by the iron plates. Reducing heat loss.
In some embodiments, the first sheet 7 component and the second sheet 8 component are bonded to both sides of the insulation 9. The first plate 7 component and the second plate 8 component are bonded on two sides of the heat insulation layer 9 through high-temperature-resistant glue, so that heat loss can be reduced to the maximum extent.
In some embodiments, the thickness value of said first sheet 7 is greater than the thickness value of the second sheet 8. Typically, the thickness of the first sheet 7 is 1-3 times the thickness of the second sheet 8. In the case of such a ratio, a good heat insulation effect can be obtained. In addition, it should be noted that, in the reverse case, the thickness value of the first plate 7 is smaller than that of the second plate 8, which can also have the effect of preventing heat dissipation.
In some embodiments, the first bezel structure 10 and the second bezel structure 11 are 30-50cm apart. At the distance, the heat bridge formed by the iron plates is reduced to dissipate heat, and the heat loss can be greatly reduced.

The advantages that may be provided by the insulation panel structures disclosed herein include, but are not limited to: 1) Splicing gaps: because the drying equipment belongs to large-scale non-standard equipment, the manufacturing and the installation of the equipment are all completed on a construction site, the drying equipment is completed by splicing, and splicing gaps cannot be avoided. However, the splicing gaps can be provided, and heat cannot overflow, so that a staggered joint mode can be adopted, and direct overflow of heat is avoided. 2) Splicing the thermal bridge: because the spliced rabbet-type iron plate forms a heat bridge, the heat transfer is intensified. In order to isolate the thermal bridges, the space between the thermal bridges is filled with 20mm aluminium silicate rock wool, so that the heat is blocked.
It is to be noted that different embodiments may produce different advantages, and in different embodiments, any one or combination of the above advantages may be produced, or any other advantages may be obtained.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
