Abstract
The utility model relates to a water temperature control device of an air-cooled extruder. The extruder is connected with an air-cooled radiator through a pipe. Radiating fins are arranged at the bottom of the radiator, and a fan is arranged above the radiating fins. A control device for controlling rotation speed of the fan is arranged on the radiator. The difference between the water temperature control device of the air-cooled extruder and a conventional water temperature control device is that the original plate-type heat exchanger is replaced by the air-cooled radiator, external circulating water is replaced by the fan, and accordingly an external circulating water circulation system is omitted. The water temperature control device keeps the advantages as the conventional device, namely internal circulating water of the extruder is still in closed circulation, so that quality of the internal circulating water can be guaranteed; and further overcomes all defects of the conventional device, namely overcomes defects that the external circulating water circulation system is high in energy consumption and water usage, low in heat exchange efficiency and high in investment, the conventional radiator is easy to be blocked, and the like.

Technical field
The utility model relates to a kind of device that belongs to the interior circulating water temperature of control extruder of machinery manufacturing technology field, particularly a kind of air-cooled extruder water temperature control device.
Background technology
The extruder water temperature control device mainly is the water-cooled water temperature control device at present.So-called water-cooled water temperature control device refers to that the interior recirculated water (passing into the recirculated cooling water of extruder) of extruder water temperature control device does not directly contact with outer circulation water (passing into the cooling water that plate type heat exchanger is interior circulating water cooling), and the heat exchange of internal and external circulating water is finished by plate type heat exchanger.The advantage of this water temperature control device is that recirculated water can adopt demineralized water and sealing and circulating in the extruder, and the cooling water of extruding machine road is less scaling, makes extruder be in for a long time good heat exchange state.Its shortcoming mainly contain following some: 1, this heat exchange mode heat exchange efficiency is lower.Outer circulation water is interior circulating water cooling by heat exchanger, and outer circulation water must be through twice heat exchange again by being installed in outdoor open cooling tower cooling.2, because the outer circulation hydromining is lowered the temperature with open cooling tower, water directly with extraneous contact, so outer circulation water water quality is relatively poor, thereby causes radiator fouling even obstruction, further reduces heat exchange efficiency.3, outer circulation water pump house generally from extruder away from, the outer circulation water lines is long, pipe decreases large, pump head high (general 40 meters) except needs are equipped to water pump, also need be equipped with back water pump, so power consumption is large in addition.4, the open cooling tower water rate of wafing is high, and outer circulation damage by water consumption is large, generally about 3%.5, pump house needs special station and pond (minute water feeder and back pool), not only need be equipped to water pump, also need be equipped with back water pump, and pipeline is long in addition, and the investment of outer circulation water circulation system is large.
The utility model content
The purpose of this utility model is to provide a kind of air-cooled extruder water temperature control device, can solve that existing water-cooled extruder water temperature control device and outer circulation water system power consumption are high, water content consumption is large, heat exchange efficiency is low and easily stops up and problem that the circulation investment is large.
For achieving the above object, technical solutions of the utility model are realized:
A kind of air-cooled extruder water temperature control device, extruder is connected with radiator by pipeline, and described radiator is fan-cooled radiator.
Wherein, the bottom of described radiator is fin, and the top of fin is blower fan.
In addition, the bottom of radiator is blower fan, and the top of blower fan is fin.That is: the position of blower fan and fin can be adjusted.
Wherein, be provided with the control device of control rotation speed of fan on the radiator, by the temperature of control rotation speed of fan controlled circulation water.
Particularly, air-cooled extruder water temperature control device is exactly that the plate type heat exchanger that will have the water-cooled water temperature control device now makes fan-cooled radiator into.Fan-cooled radiator is comprised of fin, blower fan and water temperature control system.
Recirculated water is stored in the water tank in the extruder, and to enter the cooling water of extruding machine road by interior water circulating pump be extruder cooling, enter fan-cooled radiator through extruder heating is laggard, by returning cyclic water tank after the fan-cooled radiator cooling, form a closed cycle.Interior recirculated water is complete closed in the process of circulation, so water quality can not polluted, can guarantee the water quality of interior recirculated water, guarantees extruder cyclic water channel non flouling behaviour.The return water temperature of recirculated water is generally between 65 ℃～90 ℃ in the extruder.After hot water entered fan-cooled radiator, the air at room temperature that blower fan blows out carried out heat exchange with the fin of radiator, and the heat of the interior recirculated water in the radiator is taken away.In order to control the temperature of recirculated water in the extruder, by the control device of the control rotation speed of fan that arranges on the radiator, according to the height of circulating water outlet temperature in the extruder rotating speed of blower fan is controlled.In addition, when extruder needs preheating, can directly enter extruder by the preheating pipeline without fan-cooled radiator through the interior recirculated water after the heating extruder is carried out preheating, perhaps circulating water temperature is spent when hanging down in cold weather, and interior recirculated water also can directly enter extruder by the preheating pipeline without fan-cooled radiator and circulate.
Air-cooled extruder water temperature control device has replaced original panel radiator with fan-cooled radiator exactly with the maximum difference of water-cooled extruder water temperature control device, has replaced outer circulation water with blower fan, thereby has saved the outer circulation water circulation system.This device has kept the advantage of original device, be that recirculated water remains closed cycle in the extruder, can guarantee the quality of interior recirculated water, but overcome all shortcomings of original device, i.e. outer circulation water circulation system power consumption is high, water content consumption is large, heat exchanger effectiveness is low and radiator easily stops up and the outer circulation water system is invested the shortcomings such as large.
The advantage of air-cooled extruder water temperature control device:
(1) air-cooled extruder water temperature control device has replaced original panel radiator with fan-cooled radiator exactly with the maximum difference of water-cooled extruder water temperature control device, replaced outer circulation water with blower fan, thereby saved outer circulation water circulation system (being traditional circulating pump room), so the saving construction investment generally can be saved about 60%.
(2) this device has kept the advantage of original device, be that recirculated water remains closed cycle in the extruder, can guarantee the quality of interior recirculated water, but overcome all shortcomings of original device, i.e. outer circulation water circulation system power consumption is high, water content consumption is large, heat exchanger effectiveness is low and radiator easily stops up and the outer circulation water system is invested the shortcomings such as large.
(3) interior circulating water temperature is high, and is large with the room temperature temperature difference, and only carries out a heat exchange, so heat exchange efficiency is higher than twice traditional heat exchange.
(4) water saving.Fan-cooled radiator is only by the air heat radiation, and what drain is hot-air, thus saved outer circulation water fully, thus the consumption of outer circulation water has been dropped to zero.
(5) economize on electricity.Air-cooled extruder water temperature control device why economize on electricity be because: 1, replaced outer circulation water circulation system (comprising pump house, pond, recirculated water feed pump, recirculated water back water pump and circulation line etc.) with fan-cooled radiator and blower fan, 30% of the traditional circulating pump room of its power consumption deficiency.
(6) fan-cooled radiator inside is less scaling, has overcome heat exchanger internal incrustation problem.
