Problems solved by technology
This type of furnace oil curtain nozzle has an irregular shape of the nozzle oil curtain (uneven and discontinuous oil curtain), cannot effectively separate the oil surface of the heating furnace and the oil tank, and easily allows oil and gas to enter the heating furnace, which cannot be effectively controlled Due to the shortcomings of the atmosphere in the furnace, the processed workpieces generally show large deviations in surface hardness and black color.

The invention discloses an oil curtain nozzle device which comprises a shell forming a nozzle, an oil inlet and an oil outlet which are formed in one side of the shell, a first oil cavity, a second oil cavity and a third oil cavity, wherein the first oil cavity comprises a side end surface and a separating surface; the oil inlet is formed in the side end surface; the separating surface is provided with a first guide opening; the second oil cavity comprises a through surface and a first clapboard, wherein the through surface is provided with a second guide opening, the first clapboard is arranged between the separating surface and the second guide opening, extends upwards from one surface of the through surface and is higher than the first guide opening, and the second oil cavity is connected with the first oil cavity through the separating surface; the third oil cavity comprises a second clapboard and an outer side surface, wherein the second clapboard is arranged between the second guide opening and the outer side surface and extends downwards from the other surface of the through surface, and an oil outlet is formed at the upper end of the outer side surface. According to the oil curtain nozzle device, quenching oil reaches the oil outlet after multiple buffering so as to ensure that the pressure of the quenching oil reaching the oil outlet along the nozzle direction is consistent, and thus an oil curtain is flat and continuous in shape.
Description
technical field [0001] The invention relates to a nozzle device, in particular to an oil curtain nozzle device in which the oil curtain is formed smoothly and continuously. Background technique [0002] Mesh belt furnace oil curtain nozzle in the prior art, such as Figure 4 , Figure 5 As shown in , the quenching oil enters the oil from the oil inlet 1 to sprays out from the oil nozzle 3, and passes through an oil chamber 2 that gradually shrinks. Figure 5 The mounting flange 4 and the blind flange 5 in it play a fixed role. This type of furnace oil curtain nozzle has irregular shape of the nozzle oil curtain (uneven and discontinuous oil curtain), cannot effectively separate the oil surface of the heating furnace and the oil tank, and easily allows oil and gas to enter the heating furnace, which cannot be effectively controlled Due to the shortcomings of the atmosphere in the furnace, the processed workpieces generally show large deviations in surface hardness and black...
