Abstract
The utility model provides an air channel cooling device, and relates to the technical field of cooling devices, and the air channel cooling device solves the problems that an existing device is poor in cooling effect, and is high in defective percentage. The air channel cooling device comprises an air inlet, an air channel cylinder body and an air outlet. The air channel cooling device is characterized by also comprising an auxiliary air inlet and a reducing opening; the auxiliary air inlet is arranged in the upper end of the air channel cylinder body; one end of the reducing opening is communicated with the air inlet, and the other end of the reducing opening is communicated with the air channel cylinder body. The air channel cooling device is not restricted by places, is low in cost and expense by virtue of simple modification, and can be used for improving the cooling effect obviously.
Description
Technical field
The utility model relates to a kind of cooling device, particularly relates 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 extrusion molding process, 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 push, the diameter of particle is determined by the discharge opening diameter of discharge port plate, length determines by the rotary speed of cutting knife, and temperature when particle enters air channel cylindrical shell is 130 ° of left and right, due to the material behavior of particle itself, between particle, there is certain viscosity, generally viscosity is directly proportional to temperature, thus must be cooling immediately when particle enters air channel cylindrical shell, otherwise the inter-adhesive substandard products that cause between particle.Now domestic all cooling be all the cooling method that adopts single air channel, when wind enters from air inlet, due to the position of importing and exporting all below, cause most cooling air directly from air outlet, to go out, heat exchange is carried out on the top of only having a small amount of cooling air to enter into air channel cylindrical shell, cooling effect is bad, the heat exchange that is mainly top does not almost have, when the output of extruder is not high, cooling effect is all right, if the output of extruder is high, the speed of discharging is fast, and when the viscosity of raw material self is fine again, the scrappage of product improves greatly.
Therefore, instantly need the urgent technical problem solving to be exactly: a kind of effective measures of proposition how can innovate, to meet the demand of practical application.
Utility model content
For the weak point existing in the problems referred to above, the utility model provides a kind of air channel cooling device, makes it not be subject to place restriction, by simple, transform, and cost is cheap, and cooling effect is significantly improved.
In order to address the above problem, the utility model provides a kind of air channel cooling device, comprise air inlet, air channel cylindrical shell and air outlet, wherein, also comprise auxiliary air inlet and reducing mouth, described auxiliary air inlet 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 is positioned at the opposite side of air inlet.
Preferably, the diameter of described reducing mouth reduces gradually along the mobile direction of cooling air.
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 utlity model has following advantage:
1, the utility model is by the design of auxiliary air inlet, and region of no pressure and cooling-air that particle above can fully be entered into below carry out heat exchange, and with low cost, cooling effect improves greatly, and the qualification rate of product is significantly improved.
2, the utility model, by variable diameter design, produces region of no pressure, and the flowing velocity of particle is accelerated, and realizes cooling air and make Laminar Flow in the cylindrical shell of air channel, is conducive to heat exchange, and the efficiency of heat exchange improves.
3, the utility model is without reforming equipment and increase equipment, as long as slightly change and can realize on original equipment, with low cost.
Accompanying drawing explanation
Fig. 1 is example structure schematic diagram of the present utility model.
Main element symbol description:
1-air channel cylindrical shell 2-air inlet 3-reducing mouth
4-air outlet 5-region of no pressure 6-assists air inlet
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and example, the utility model is described in further detail, but example is not as to restriction of the present utility model.
As shown in Figure 1, embodiment of the present utility model comprises fresh air inlet 2, air channel cylindrical shell 1 and air outlet 4, wherein, also comprise auxiliary air inlet 6 and reducing mouth 3, auxiliary air inlet 6 is arranged on the upper end of air channel cylindrical shell 1, and auxiliary air inlet 6 is positioned at the opposite side of air inlet 2, and reducing mouth 3 one end are communicated with air inlet 2, the other end is connected with air channel cylindrical shell 1, and the diameter of the port of reducing mouth 3 reduces gradually along the mobile direction of cooling air.
After work starts, when particle enters into air channel cylindrical shell 1, air inlet 2 and auxiliary air inlet 6 be air intake simultaneously, variable diameter design due to air inlet 2, cooling air enters into bottom when motion of air channel cylindrical shell 1 by reducing mouth 3, flow velocity will strengthen, the cooling air of rapid flow can produce certain region of no pressure 5 around at it, the high speed cooling air of bottom can produce a low pressure simultaneously, and then the particle that brings of the rotary wind that can effectively siphon away top, particle 5 is concentrated to region of no pressure fast, and together with cooling air, entered into air outlet 4 after carrying out heat exchange with cooling air.In the upper end of air channel cylindrical shell 1, install an auxiliary air inlet 6 simultaneously additional, cooling air enters from auxiliary air inlet 6, produce certain speed, the cooling air of certain flow flows along counterclockwise direction, particle high-order is carried out fully cooling at high level, and region of no pressure and cooling-air that particle above can fully be entered into below carry out heat exchange, now the cooling air of the particle in air channel cylindrical shell 1 by air inlet 2 and auxiliary air inlet 6 fully cooling after, the temperature fast-descending of particle, arrive air outlet 4 places and can produce the phenomenon of adhesion hardly, cooling successful improves.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
