Technical Field
The utility model relates to a cooling device especially relates to a bolt cooling device.
Background
After the production of the bolt is finished, in order to enhance the corrosivity of the bolt, a zinc layer needs to be plated on the surface of the bolt. The thickness of the hot-dip galvanized layer is generally above 35 μm and even up to 200 μm. During hot galvanizing, the temperature of zinc water is about 500 ℃, after the hot galvanizing is finished, in order to accelerate the hardening of the zinc water on the surface of a bolt and the rapid reduction of the temperature, the mutual adhesion and the burning of threads after a large number of bolts are accumulated are prevented, the bolt needs to be cooled after the hot galvanizing, the bolt taken out from a zinc water tank is put into cold water for water cooling, the temperature of the selected cold water is generally 4-25 ℃, the temperature of the bolt is sharply reduced to 4-15 ℃ from 500 ℃, the bolt can be subjected to a tempering process, the strength of the bolt can be reduced, and meanwhile, the temperature difference is too large, the adhesive force of a zinc layer on a base body can be influenced, and the uneven gloss of the surface of the bolt is unqualified. Therefore, a new technical solution should be provided to solve the above problems.
Disclosure of Invention
The utility model aims at: aiming at the defects, the bolt cooling device with reasonable structure and good use effect is provided.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a bolt cooling device, includes cooling box A, sets up at cooling box B, the frame at cooling box A rear, a set of conveying wheel that drives rotatoryly by power unit and the conveyer belt of setting on the conveying wheel, the conveyer belt passes cooling box A and cooling box B in proper order, cooling box A upper end is equipped with the air-supply line, is provided with cooling blower in the air-supply line, the lower extreme of air-supply line is connected with a plurality of air-out shower nozzle, the upper portion of stoving box is through mounting still fixed mounting have a plurality of fans, the coolant liquid has been held in the cooling box B.
The further technical scheme is as follows:
the installation height of the fan is lower than the height of the air outlet nozzle.
The conveyer belt is a net type conveyer belt.
The diameter of the mesh on the mesh type conveying belt is smaller than the minimum diameter of the conveyed bolt.
