Problems solved by technology

However, the traditional hot presses in the traditional wood products industry mostly use coal or wood veneer waste, which causes serious pollution.
Due to the use of combustibles for combustion, there are potential safety hazards, and the boiler needs to be equipped with a dust removal system. At present, the dust removal system also has safety hazards and certain safety risks. Therefore, the traditional coal-fired or wood veneer waste boilers are gradually eliminated.

Embodiment 1

[0029] Such as Figure 1 to Figure 6 As shown, a kind of electric boiler equipment is applied to pressing wood products, including a hot press for pressing multi-layer wood boards 5, and the hot press is connected with heating equipment for heating the hot press. In this embodiment The heat supply equipment is an electric boiler. The electric boiler heats the heat transfer fluid, and then transports the heat transfer fluid to the hot press to provide heat for the hot press. The electric boiler includes a heating furnace 1 and a heat preservation furnace connected to the heating furnace Furnace 2, the heating furnace 1 is provided with a heating assembly 11 for heating the heat transfer fluid, and the holding furnace 2 is provided with a heat preservation assembly 21 for insulating the heat transfer fluid, and the heating furnace 1 transports the heated heat transfer fluid To the hot press, the heat transfer fluid flows back to the holding furnace 2 after working in the hot pre...

Embodiment 2

[0043] Such as Figure 7 As shown, the difference from Embodiment 1 is that the main heating chamber 13 in this embodiment is a hollow cylinder, the convection channel 15 is arranged at the bottom of the side wall of the cylinder, and the heating assembly 11 is also arranged at the main Below the heating chamber 13, the volume of the main heating chamber 13 is larger than that of Embodiment 1, and the heat transfer fluid that can be transported at one time is more, which is suitable for large-scale heat presses.

Embodiment 3

[0045] Such as Figure 8 As shown, the difference with Embodiment 1 is that the structure of the micro-pressure valve 24 is different. The micro-pressure valve 24 in this embodiment includes a shell 246, and the heat preservation cavity 22 is provided with a vent hole 221, and the inner wall of the shell 246 A conical ring wall 247 is provided, and a ball 248 is placed on the conical ring wall 247. When the ball 248 is pressed onto the conical ring wall 247, it just blocks the vent hole from the outside air pressure. When the air pressure is high, the ball 248 is pushed away, and the gas is discharged from the gap between the ball 248 and the conical ring wall 247; The vent hole 221 is isolated from the external air pressure.

Abstract

The invention discloses electric boiler equipment applied to wooden product pressing. The electric boiler equipment comprises a hot press for pressing a plurality of layers of wood boards; the hot press is connected with heat supply equipment for supplying heat to the hot press; the heat supply equipment is an electric boiler; the electric boiler comprises a heating furnace and a thermal-insulation furnace communicating with the heating furnace; a heating assembly for heating a heat conducting fluid is arranged in the heating furnace; a thermal-insulation assembly for preserving heat of the heat conducting fluid is arranged in the thermal-insulation furnace; the heating furnace is used for conveying the heated heat conducting fluid to the hot press; and after working in the hot press, the heat conducting fluid flows back to the thermal-insulation furnace. The electric boiler equipment has the advantages of being quick in heating up, high in heating efficiency, efficient and economical.

Description

【Technical field】 [0001] The invention relates to an electric boiler equipment used for pressing wood products, which belongs to the field of electric equipment. 【Background technique】 [0002] The wood products industry, especially wood boards, basically uses the pressing process in the production process, that is, the composite pressing of multi-layer wood boards into a whole. In this process, a hot press is usually used. This equipment passes temperature, pressure and production speed. The precise fit of the slab quickly solidifies the adhesive in the slab and presses the slab into shape. However, the traditional hot presses in the traditional wood products industry mostly use coal or veneer waste, which causes serious pollution. Due to the use of combustibles for combustion, there are potential safety hazards, and the boiler needs to be equipped with a dust removal system. At present, the dust removal system also has safety hazards and certain safety risks. Therefore, t...
