Description
Technical field
The present invention relates to a kind of cooling device, particularly relate to a kind of air channel cooling device.
Background technology
Now domestic extruder in process of production, the particle that it produces all needs cooling, because extruder is exactly to raw material (PE in process of production, the plastics such as PU or nylon product) heating and stirring, then a process of extrusion molding, particle specification after extruding is generally diameter 2-3mm, length 2-5mm.Particle is used as raw material to injection machine, extruder normally adopts screw rod to extrude, the diameter of particle is determined by the discharge opening diameter of discharge port plate, length is determined by the rotary speed of cutting knife, temperature when particle enters air channel cylindrical shell at about 130 °, due to the material behavior of particle itself, certain viscosity is there is between particle, generally viscosity is directly proportional to temperature, so must cool immediately when particle enters air channel cylindrical shell, otherwise inter-adhesively between particle causes substandard products.Present domestic all coolings are all the cooling methods adopting single air channel, when wind enters from air inlet, due to import and export position all below, most cooling air is caused directly to go out from air outlet, heat exchange is carried out on the top only having a small amount of cooling air to enter into air channel cylindrical shell, cooling effect is bad, mainly the heat exchange on top does not almost have, when the output of extruder is not high, the effect of cooling is all right, if the output of extruder is high, the speed of discharging is fast, and the viscosity of raw material self again very well time, the scrappage of product improves greatly.
Therefore, instantly need the urgent technical problem solved exactly: a kind of effective measures of the proposition how can innovate, to meet the demand of practical application.
Summary of the invention
For the weak point existed in the problems referred to above, the invention provides a kind of air channel cooling device, make it not by place restriction, by simple transformation, cost is cheap, and cooling effect is significantly improved.
In order to solve the problem, the invention provides a kind of air channel cooling device, comprise fresh air inlet, air channel cylindrical shell and air outlet, wherein, also comprise auxiliary air inlet mouth and reducing mouth, described auxiliary air inlet mouth is arranged on the upper end of described air channel cylindrical shell, and described reducing mouth one end is communicated with described air inlet, and the other end is connected with described air channel cylindrical shell.
Preferably, described auxiliary air inlet mouth is positioned at the opposite side of air inlet, and the cooling air flowing through it makes particle above fully can enter into region of no pressure below and cooling-air carries out heat exchange.
Preferably, the direction that the diameter of described reducing mouth flows along cooling air reduces gradually, thus makes cooling air flow velocity strengthen, produce low High Voltage and produce region of no pressure around it.
Preferably, particle set is carried out heat exchange in described region of no pressure and cooling air by pressure differential by described air channel cylindrical shell.
Preferably, described air inlet and described air outlet lay respectively at cylindrical shell both sides, described air channel, and are connected with described air channel cylinder body bottom respectively.
Compared with prior art, the present invention has the following advantages:
1, the present invention is by the design of auxiliary air inlet mouth, makes particle above fully can enter into region of no pressure below and cooling-air carries out heat exchange, and with low cost, cooling effect improves greatly, and the qualification rate of product is significantly improved.
2, the present invention is by variable diameter design, produces region of no pressure, the flowing velocity of particle is accelerated, realizes cooling air and make Laminar Flow in the cylindrical shell of air channel, be conducive to heat exchange, and the efficiency of heat exchange improves.
3, the present invention is without the need to reforming equipment and increase equipment, can realize as long as slightly change on original equipment, with low cost.

Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing and example, the present invention is described in further detail, but example is not as a limitation of the invention.
As shown in Figure 1, embodiments of the invention comprise fresh air inlet 2, air channel cylindrical shell 1 and air outlet 4, wherein, also comprise auxiliary air inlet mouth 6 and reducing mouth 3, auxiliary air inlet mouth 6 is arranged on the upper end of air channel cylindrical shell 1, and auxiliary air inlet mouth 6 is positioned at the opposite side of air inlet 2, and reducing mouth 3 one end is communicated with air inlet 2, the other end is connected with air channel cylindrical shell 1, and the direction that the diameter of reducing mouth 3 flows along cooling air reduces gradually.
After work starts, when particle enters into air channel cylindrical shell 1, air inlet 2 and auxiliary air inlet mouth 6 air intake simultaneously, due to the variable diameter design of air inlet 2, cooling air enters into the bottom motion of air channel cylindrical shell 1 during by reducing mouth 3, flow velocity will strengthen, the cooling air of quick flowing can produce certain region of no pressure 5 around it, the Fast Cooling wind of bottom can produce a low pressure simultaneously, and then the particle that the rotary wind that can effectively siphon away top brings, particle is concentrated to region of no pressure 5 fast, and carries out together with cooling air, entering into air outlet 4 after heat exchange with cooling air.Install an auxiliary air inlet mouth 6 additional in the upper end of air channel cylindrical shell 1 simultaneously, cooling air enters from auxiliary air inlet mouth 6, produce certain speed, the cooling air of certain flow flows along counterclockwise direction, particle in a high position is fully cooled at high level, and make particle above fully can enter into region of no pressure below and cooling-air carries out heat exchange, after particle now in air channel cylindrical shell 1 is fully cooled by the cooling air of air inlet 2 and auxiliary air inlet mouth 6, the temperature of particle declines fast, arrive the phenomenon that air outlet 4 place produces adhesion hardly, the successful of cooling improves.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
