The to-be-solved technical problem of the utility model is to provide a modified extruder unloading section cooling device, can solve the not enough of prior art, realize cooling zone's subregion accurate control.
In order to solve the technical problem, the utility model adopts the following technical proposal.
An improved cooling device for a discharging section of an extruder comprises a discharging pipe, wherein a cooling water pipe is sleeved on the outer side of the discharging pipe, a water inlet channel and a water outlet channel which are connected with each other are arranged in the cooling water pipe, the water inlet channel is positioned on the outer side of the water outlet channel, a heat insulation plate is arranged between the water inlet channel and the water outlet channel, the cooling water of the water inlet channel flows from the initial end to the tail end of the discharging pipe, and the cooling water of the water outlet channel flows from the tail end to the initial end of the discharging pipe; the cooling water pipe is provided with a plurality of metal adjusting rotary rods, the cooling water pipe and the metal adjusting rotary rods are perpendicular to each other, a first copper foil is wound on the part, located in the water inlet channel, of each metal adjusting rotary rod, the outer side end of each first copper foil is connected to the inner wall of the water inlet channel through a first spring, a second copper foil is wound on the part, located in the water outlet channel, of each metal adjusting rotary rod, the outer side end of each second copper foil is connected to the inner wall of the water outlet channel through a second spring, and a plurality of slits are formed in each second copper foil; and a sealing washer is arranged at the joint of the metal adjusting rotary rod, the cooling water pipe and the heat insulation plate, and a locking nut is sleeved at the top of the metal adjusting rotary rod.
Preferably, the surface of the metal adjusting rotary rod in the water outlet channel is provided with a spiral diversion trench.
Preferably, a nitrogen circulating pipe is arranged in the metal adjusting rotary rod.
Adopt the beneficial effect that above-mentioned technical scheme brought to lie in: the utility model discloses at first divide cooling water pipe for inhalant canal and exhalant canal to the realization is opposite with ejection of compact pipe contact's rivers direction in the exhalant canal and ejection of compact direction, thereby can improve the uniformity of raw materials and cooling water difference in temperature among the different positions. The cooling water in the water outlet channel is used for directly contacting with the discharge pipe to realize cooling, and the cooling water in the water inlet channel conducts heat in the water outlet channel outwards through the heat conductivity of the metal adjusting rotary rod. This is equivalent to that the cooling water realizes twice heat absorption in the water inlet channel and the water outlet channel, thereby improving the whole cooling efficiency. The first copper foil and the second copper foil are unfolded and recovered through the rotation of the metal adjusting rotary rod. The larger the contact area of the copper foil with the cooling water, the higher the thermal conductivity of the metal tuning screw. Therefore, the heat conduction efficiency of cooling water at different positions can be realized by rotating the metal adjusting rotary rod. The slits on the second copper foil can improve the flow distribution uniformity of cooling water in the water outlet channel. The spiral diversion trench can enable cooling water flowing through to generate turbulent flow, and further improves the flowing distribution uniformity of the cooling water in the water outlet channel. In order to further improve the regulation of the cooling efficiency of different cooling areas, a nitrogen circulating pipe is arranged in the metal regulating rotary rod, and the change range of the heat conduction efficiency of the metal regulating rotary rod is further improved by utilizing low-temperature nitrogen.
