The strong cold house of application cyclone tuyere
Technical field
The utility model relates to the strong cold house of a kind of application cyclone tuyere.
Background technology
Behind the vehicle spray painting paint drying, the bodywork surface temperature reaches about 140 degree, must force just can carry out the production of next process after the cooling through strong cold house, and present strong cold house all needs 2 station length usually, and occupation of land is big and cooling-down effect is undesirable.
The strong cold house of application comprises strong cold house body, supply and exhaust device, indoor airduct, the universal compositions such as tuyere of regulating, strong cold house supply and exhaust device is made up of two blower fans, filter course, blast pipe, discharge pipe etc., workshop air is sucked by air inlet by a blower fan, oil removing dewaters through filter course, arrive the tuyere air inlet through indoor airduct, be ejected into bodywork surface by tuyere, vehicle body is forced cooling, and another blower fan continuous exhausting in the strong cold house, discharge through exhaust outlet, keep the blast of strong cold house to be slightly larger than outdoor simultaneously.Traditional universal general mode that adopts vertical injection vehicle body of tuyere of regulating, cold wind blows to heat up on the vehicle body discharges outdoor from the indoor airduct of top via the air draft pipeline then.
The universal adjustable tuyere of tradition, the wind that blows out from tuyere is ejected on the vehicle body, looses at bodywork surface and flows, and it is less to form cyclone, has a lot of wind convection current to consume, and energy consumption is big.
Summary of the invention
The purpose of this utility model is the strong cold house of the application cyclone tuyere that will provide a kind of cooling effect to significantly improve.
The utility model realizes that the technical scheme of above-mentioned purpose is, the strong cold house of a kind of application cyclone tuyere, comprise solar or lunar halo, its improvement is: also be fixed with impeller in the described solar or lunar halo, described impeller comprises fixed axis and blade, one end and the solar or lunar halo inner periphery of described blade are fixed, and the other end and fixed axis are fixed.
Described blade has three, and evenly distributes along the solar or lunar halo inner periphery.
Have the inclination angle between described blade and fixed axis, be clockwise or counterclockwise and arrange.
Owing to also be fixed with impeller in the solar or lunar halo of the present utility model, described impeller comprises fixed axis and blade, one end of described blade with fix along the solar or lunar halo inner periphery, the other end and fixed axis are fixed, such structural change the direction of air-flow, make air-flow more concentrated, its cooling effect is significantly increased, and can shorten strong cold house length.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
As shown in Figure 1, 2, the strong cold house of a kind of application cyclone tuyere comprises solar or lunar halo 1, also be fixed with impeller 2 in the described solar or lunar halo 1, described impeller 2 comprises fixed axis 2-1 and blade 2-2, and the end of described blade 2-2 and solar or lunar halo 1 inner periphery are fixed, and the other end and fixed axis 2-1 fix.
Described blade 2-2 has three, and evenly distributes along solar or lunar halo 1 inner periphery.
Have the inclination angle between described blade 2-2 and fixed axis 2-1, be clockwise or counterclockwise and arrange.Be convenient to adjust airflow direction like this.
The utility model when in use, the abbreviation A tuyere of arranging counterclockwise, the abbreviation B tuyere of arranging clockwise.With the A tuyere is example, and air-flow passes through at a high speed the time of the present utility model, and the stainless blade 2-2 of three counterclockwise tilt distribution is divided into three strands of air-flows with air-flow, blows out counterclockwise, and three strands of air-flows blow on the vehicle body and hindered by vehicle body, form a small-sized cyclone.
The utility model is through using collocation in twos in pairs, can form cyclone at bodywork surface, and when up and down or about two airflow directions of the present utility model be when counterclockwise, three kinds of situations are arranged, a kind of is that the air-flow of two nozzles does not contact and blown to separately on the vehicle body, a kind of is that the air-flow of two nozzles does not contact vehicle body and promptly forms cyclone aloft and consume, a kind of is that the air-flow of two nozzles forms bigger cyclone at bodywork surface, and air-flow is when bodywork surface forms big more many more cyclones, and cooling effect is just good more.And when the adjacent laying of A tuyere B tuyere,, form flow-disturbing at the air-flow contact position because the direction of air-flow is opposite, can cause cooling effect to reduce.
As from the foregoing, under the situation that keeps three leaf cyclone tuyere air-out unanimities, regulate, can obtain to be sprayed onto formed cyclone on the bodywork surface, thereby promote the cooling effect of strong cold house greatly far more than common universal tuyere by direction.
Therefore, need adjust the angle of three leaf cyclone tuyeres of strong cold house,, improve cooling effectiveness to obtain more cyclone as far as possible at bodywork surface according to the vehicle body situation of application workshop actual production.Use the strong cold house that three leaf cyclone tuyeres of the present utility model are built, the strong cold house length of using the strong cold house of traditional universal adjustment tuyere can save 0.5-1 station, the vehicle kind in workshop is few more, the vehicle width is approaching more, adjusts to best cooling effect just easily more, simultaneously, can select the less blower fan of blast, reduce energy consumption, reduced the workshop noise, helped the healthy of workman.
