Description

A kind of rain-tight device of rectangular air box

Technical field

The utility model relates to a kind of improvement of air box, more particularly to, a kind of rectangular air box rain-tight device Improvement.

Background technique

In the prior art, axial flow blower is called booster, is exactly and the axis of fan blade equidirectional air-flow (the i.e. stream of wind To parallel with axis), such as electric fan, it is a kind of industrial and mining enterprises' commonly wind that outdoor machine of air-conditioner fan, which is exactly that axis stream mode runs blower, Machine, it is different from general blower.For the motor and fan blade of conventional axial flow blower all in a cylinder, shape is exactly a cylinder Shape is used for local ventilation, and easy for installation, ventilation effect is obvious, and safety, the cylinder that can give a dinner for a visitor from afar, which is kept watch, is sent to specified region. And rectangular axial flow blower, the maximum difference with conventional axial flow blower are, the motor and fan blade of rectangular axial flow blower are all at one In cylinder, and shape air box be it is rectangular, it is more convenient than cylinder type assembling.

Rectangular axial flow blower is using the cool principle of cross-ventilation, negative pressure ventilation, by the opposite direction of infield --- gate Or window sucks fresh air naturally, forces discharge outdoor rapidly indoor sultry gas, any improper ventilation problem can change Kind, the ventilation effect that cools down is up to 90%-97%.

Air box is composed of profile and board material splice first, and there are gaps for interface；Secondly because ventilation blower Characteristic, so will form negative pressure inside air box, thus blower can may suck external rainwater at work from internal air draught Inside air box, thus the ventilation blower of rectangular air box outdoor environment work when, when the weather of snowy day on rainy day, generally It will appear roof leaking, seep the case where rain, therefore result in the damage of ventilation blower inner components burn into, greatly reduce ventilation blower Service life.Existing usual way is at the top of rectangular air box plus rain-proof top plate, the splicing of tank surface plate break silica gel at gap Deng.

But at the top of existing rectangular air box plus the technical solution of rain-proof top plate has the following problems: first is that increasing ventilation blower Overall cost；Second is that rain-proof top plate only covers ventilation blower top area, front and back and side do not play a bit rain-proof effect Fruit, thereby increases and it is possible to influence the maintenance of blower；Third is that being just not suitable for also being difficult to install rain-proof top plate when the motor overhead of ventilation blower.

And the scheme that the prior art breaks silica gel at tank surface plate splicing gap has the following problems: first is that silica gel is anti- The mechanical performances such as Zhang Qiangdu and tearing toughness are poor, so can be dry and cracked in situation wet by the rain and burnt by the sun, it falls off, second is that silica gel inferior The time long mouldy blackening of meeting, influences the appearance of ventilation blower.

Therefore, there is also defects for the prior art, to be further improved and developed.

Utility model content

The purpose of this utility model is to provide a kind of rain-tight devices of rectangular air box, pass through the aluminium profiles to air box On the one hand the optimization and improvement of material, sealing strip and sealant assembly technology are able to solve air box roof leaking, seep the problem of rain, separately On the one hand the cost of ventilation blower can be reduced.

The technical solution of the utility model is as follows:

A kind of rain-tight device of rectangular air box is arranged on rectangular air box, the frame of the rectangular air box Frame setting uses double flute profile, wherein sealing strip is provided in the double flute of the profile, and along the sealing strip coated with close Sealing compresses the sealant and sealing strip assembly for the rectangular air box.

The rain-tight device of the rectangular air box, wherein the sealing strip be provided with two of predetermined space with On, and sealant is coated between the sealing strip.

The rain-tight device of the rectangular air box, wherein the sealant completely covers the double flute of the profile.

The rain-tight device of the rectangular air box, wherein the sealant setting uses silica gel.

The rain-tight device of the rectangular air box, wherein the profile uses aluminum profile.

The rain-tight device of any rectangular air box, wherein the assembly screws tight assembly using fastener.

The rain-tight device of a kind of rectangular air box provided by the utility model, due to using in aluminum profile double-groove Sealing strip and sealant along sealing strip coating setting, reduced on the basis of solving the roof leaking of rectangular air box, seeping rain The cost of ventilation blower.

Specific embodiment

The preferred embodiment of the utility model is described in detail below.

In the preferred embodiment of the rain-tight device of rectangular air box described in the utility model, the rectangular air box 100 As shown in Figure 1 to Figure 3, the front and back side end face of rectangular air box 100 is air duct inlet and outlet, it usually needs pipeline is separately arranged and connects It connects, so as to by direction required for distinguished and admirable guiding.The rectangular air box 100 generallys use profile 101 as frame support knot Structure supports the panel 102 on periphery to form rectangular air box 100.The profile 101 is typically but not limited to using aluminum profile.

Rectangular air box rain-tight device described in the utility model is mainly used for outdoor rain-tight, such as Fig. 4 and Fig. 5, Fig. 6 It is shown, in the installation assembling process of rectangular air box, need in the corner of panel-mounted position using dual-trench type aluminum profile 101, sealing strip 102 is pasted at aluminum profile double-groove, preferably but is not limited to, and the settable sealing strip 102 is two or more.Described Sealant 103 can be coated between sealing strip 102 or along the sealing strip 102, the sealant 103 commonly silica gel.

It is preferred that silica gel 103 is made at 101 turning of aluminum profile and 102 middle of sealing strip, when rectangular air box Cabinet panel 104 when being pressed on silica gel 103 and sealing strip 102, it is internal again by fastener 105 the panel 104 firmly Locking, can squeeze the ductility of the silica gel 103 and the sealing strip 102 and seal it more, and then solve air box The problem of rain, is seeped in roof leaking.The solution of the utility model is to be fastened in assembly from the inside of air box, thus will Sealant, that is, silica gel is placed on hiding position, to reduce the be may cause problem of aging that exposes to the sun and rain.

It is noted that the above-mentioned bolt fastening of the utility model is not necessarily, it can also be using other fastenings Mode, such as engaging, welding etc., as long as being capable of forming rectangular air box.

The rain-tight device of rectangular air box described in the utility model splices gap relative to adding rain-proof top plate and surface plate The way of silica gel is beaten at place, on the one hand can reduce the whole manufacturing cost of ventilation blower, and it is de- on the other hand can to prevent surface silica gel The occurrence of leading to secondary roof leaking is fallen, the rectangular air box service life that third is completed the process is firm persistently, can be entirely square Position ground protection ventilation blower, prevents the appearance that rain condition condition is seeped from side.

By taking the YFISH blower of a 900 impeller of our company as an example, the blower maximum speed 1360, air quantity 75000CMH is quiet Press 500pa, resistance to water running continues experimental period, test result be inside air box without roof leaking, seep the appearance of the case where rain, and entirely The stable degree of air box is obviously improved.

It should be understood that for those of ordinary skills, it can be modified or changed according to the above description, And all these modifications and variations all should belong to the protection scope of the appended claims for the utility model.
