The rain-proof louver air outlet transfers heat to the outside, which is not conducive to energy saving.

In addition, the traditional electric rain-proof louver tuyere, in the rainy and snowy weather in winter, the rain-proof louver blades on the outside of the rain-proof louver tuyere are prone to snow accumulation and freezing, resulting in the reduction of the effective air intake area of the louver tuyere, and the electric adjustment of the louver cannot be opened. Under these conditions, if the ventilation system chained electric rain-proof louver tuyere is opened to ventilate the plant it serves, it will not be able to guarantee the ventilation required for normal ventilation or introduce snow outside the louvers into the plant.

Utility model content

The purpose of this utility model is to provide an antifreeze and heat preservation electric rainproof louver tuyere suitable for industrial plants in cold regions, which can keep heat and save energy when it is closed in winter, and can effectively prevent snow and ice on the outside of the louver tuyere.

The technical scheme of the utility model is as follows: an antifreeze and heat preservation electric rainproof louver tuyere, including rainproof blades and electric adjustment blades arranged on the frame, wherein a self-regulating blade is set on the side of the rainproof blade facing the room Temperature electric heating cable, the end of the self-limiting temperature electric heating cable is provided with a wiring terminal, and the self-limiting temperature electric heating cable is connected to a thermostat.

Furthermore, in the antifreeze and heat preservation electric rainproof louver tuyere as described above, thermal insulation material is provided on the side of the electric adjustment blade facing the room.

Further, the above-mentioned antifreeze and heat preservation electric rainproof louver tuyere, wherein, the self-limiting temperature electric heating cable is connected from the upper end of each rainproof blade, extended to the end of the rainproof blade and connected back, forming a horizontal " U" shape, and then connected to another adjacent rainproof blade.

Further, the antifreeze and heat preservation electric rainproof louver tuyere described above, wherein the self-limiting temperature electric heating cable is fixed on the indoor side of the rainproof blade by aluminum platinum tape.

Further, the above-mentioned antifreeze and heat preservation electric rainproof louver tuyere, wherein, the heat preservation material is a polyurethane rubber and plastic insulation board, which is glued to the side of the electric adjustment blade facing the room; the thickness of the polyurethane rubber and plastic insulation board is 10mm ~ 20mm.

The beneficial effects of the utility model are as follows: The utility model adds an electric heat tracing system and heat preservation measures to the traditional electric rain-proof louver tuyere, which can keep heat and save energy when it is closed in winter, and can effectively prevent snow and condensation on the outside of the louver tuyere. Ice, and maintain a certain temperature in the narrow space formed by the fixed blade and the adjustable blade to ensure that the shaft of the electric blade does not freeze.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.

The antifreeze and heat preservation electric rainproof louver tuyere provided by the utility model adds an electric heat tracing system and heat preservation measures to the traditional electric rainproof louver tuyere. Its structure is shown in Figure 2, including the rainproof blade arranged on the frame 2 1 and the electric adjustment blade 3, the self-limiting temperature electric heating cable 4 is set on the side of the rainproof blade 1 facing the room, and the thermal insulation material is set on the side of the electric adjustment blade 3 facing the room. The insulation material is polyurethane rubber and plastic insulation board 5, the thermal conductivity is 0.034W/m·k, the thickness of the insulation material is 10mm-20mm, and the special glue is used to cover the inner side of the electrically adjustable blade 3, and the heat transfer resistance is reduced by 0.3m ² ·k/W . Taking an auxiliary boiler room in Liaoning as an example, under the condition that ventilation and rain-proof louvers are closed in winter, the louvers per unit area can reduce energy consumption by 100W, effectively saving energy.

The structure of the electric heating system is shown in Figure 3, which consists of a junction box 6, a temperature controller 7, a self-limiting temperature heating cable 4, and a terminal 8. The self-limiting temperature heating cable 4 is connected to the inner side of the rainproof blade 1 through the frame 2, and fixed with aluminum platinum tape, and connected to the electric heating cable from the upper end of each rainproof blade, and the electric heating cable extends horizontally to the end of the rainproof blade Connect it back to form a horizontal "U" shape, and then connect it to the adjacent lower rainproof blade until the last blade, and set a special terminal 8 at the end of the electric heating cable. In the same way, the electric heating cable can also be connected from bottom to top, from the lower end of each rainproof blade to the electric heating cable, and the electric heating cable extends horizontally to the end of the rainproof blade to form a horizontal "U" shape, and then Receive its adjacent upper rainproof blade, until a blade of the top, this all belongs to obvious equivalent design. In winter, set the required temperature through the thermostat and turn on the power, and the electric heating system will work. Power off for other seasons.

The electric rain-proof louver tuyere of the utility model can keep heat and save energy when it is closed in winter, and can effectively prevent snow accumulation and icing on the outside of the louver tuyere, and maintain a certain temperature in the narrow space formed by the fixed blade and the adjusting blade to ensure that the electric blade The reels are not frozen.
