Embodiment 1

[0020] like figure 1 As shown, the steel wire enters the lead quenching tank 1 to undergo sorbite transformation inside the tissue, and a suction hood 2 is installed above the lead quenching tank 1, and the lead vapor and lead oxide dust are discharged into the bottom of the purification tower 4 through the suction duct 3 . Then the clear water in the circulating pool 5 is sprayed from the top of the purification tower 4 to the purification tower 4 through the circulating water pump 6 . Where the gas passes, the pressure drop generated by the gas is greater than the pressure drop of the liquid at that point, and where the liquid flows downstream, the pressure drop generated by the fluid is greater than the pressure drop generated by the gas at this point. Therefore, the lead vapor and lead oxide dust are deposited by the sprayed water to the bottom of the purification tower 4 and discharged into the circulating pool 5, and the gas generated during the treatment process is dis...

Embodiment 2

[0022] On the basis of the above examples, if figure 1 As shown, a lead quenching lead dust treatment device includes a lead quenching tank 1, wherein a suction hood 2 is arranged above the lead quenching tank 1, and lead vapor and lead oxide dust are sent into the purification tower through the suction duct 3 At the bottom of the tower 4, the clear water in the circulating pool 5 is sprayed from the top of the purification tower 4 to the tower of the purification tower 4 by the circulating water pump 6, and the water deposited at the bottom of the purification tower 4 is discharged into the Describe circulating pool 5.

[0023] On the basis of the above embodiments, further, the pressure drop generated by the gas in the suction duct 3 is set to be greater than the pressure drop of the liquid.

[0024] On the basis of the above embodiments, further, the purification tower 4 is also connected with a fan 7 through a suction duct 3 .

[0025] On the basis of the above embodimen...

Abstract

The invention relates to a patentizing lead dust treatment device comprising a patentizing groove, wherein a suction hood is arranged above the patentizing groove; lead vapor and lead oxide dust are conveyed to the tower bottom of a purifying tower through a suction pipeline; the clean water in a circulating pool is sprayed to the tower of the purifying tower from the tower top of the purifying tower through a circulating pump; and the water participated at the bottom of the purifying tower is discharged into the circulating pool. By adopting the scheme, the patentizing lead dust treatment device is concise in structure and efficient, and can be used for solving various defects and disadvantages due to the fact that meltwater lead is adopted to carry out sorbite treatment on a bead wire at present.

Description

technical field [0001] The invention relates to a production process of bead steel wire heat treatment, in particular to a lead-quenching lead dust treatment device. Background technique [0002] In the process of producing bead steel wire, it is necessary to perform sorbite treatment on the steel wire. Because lead has good thermal stability, thermal conductivity and the ability to prevent steel wire from oxidation, the steel wire can obtain a uniform sorbite structure to obtain Good mechanical properties. However, solid lead needs to be melted during lead quenching, and the lead in the molten state will generate a large amount of lead vapor and lead oxide dust, which will cause human harm to operators and spread into the atmosphere to pollute the external environment. [0003] Therefore, there are defects in the prior art and need to be improved. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a lead-quenchin...
