Detailed Description
The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.
As shown in fig. 1 and 2, a curing oven for coating includes an oven body 1 and a fire prevention mechanism 2.
Wherein the top edge all around of oven body 1 is fixed with first guide plate 11, one side downward sloping that oven body 1 was kept away from to first guide plate 11, whole first guide plate 11 is the halfpace form that encircles oven body, and wherein, a plurality of vertical through-holes 12 that parallel have been seted up along oven body 1's circumference on the first guide plate 11.
Wherein, 2 fixed mounting in oven body 1's top of fire prevention mechanism, it is concrete, fire prevention mechanism 2 includes hollow casing 21, casing 21 bottom is connected with the oven top through support frame 3, the highly preferred 30 ~ 50cm of support frame 3, the level is fixed with baffle 22 in the casing 21, baffle 22 is casing 21 internal partitioning for two cavities, wherein, the top be first cavity 26, the below is the second cavity, a through-hole has been seted up on the baffle 22, this through-hole switches on first cavity 26 and second cavity, and, still the block has the sealing plug 23 of sealing to it in this through-hole, this sealing plug 23 can be the rubber buffer, in addition, because butadiene styrene rubber has profitable heat-resisting, fire-retardant function, consequently, the preferred butadiene styrene rubber buffer that adopts.
Wherein, the second cavity intussuseption is filled with fire-retardant granule 24, and fire-retardant granule 24 is used for supporting sealing plug 23 to prevent that sealing plug 23 from droing in the above-mentioned through-hole by oneself, and 26 inside walls of first cavity are laminated and are had insulation lining 25, and water has been deposited to 26 inboards of first cavity, and insulation lining 25 is used for keeping warm first cavity 26, avoids water because of the temperature rise vaporization.
The center of the inner bottom of the second chamber is provided with a conical second guide plate 29, and the diameter of the second guide plate is gradually enlarged from the upper end to the lower end. A plurality of sunken counter bores 27 have still been seted up to second chamber bottom, and the upper end diameter of counter bore 27 is great, and the lower extreme diameter is less, and counter bore 27 communicates second chamber bottom and external world, and the fixed packing in counter bore 27 upper end has hot melt sealing material 28, and this hot melt sealing material 28 seals counter bore 27 to make the fire-retardant granule 24 that is located first chamber 26 can not drop through counter bore 27, and in this application, the diameter of single fire-retardant granule 24 needs to be less than counter bore 27 bottom diameter.
In this application, because oven body 1 top can give off partial heat, for the heat of avoiding oven body 1 self fuses hot melt seal material 28, consequently supports fire prevention mechanism 2 through support frame 3 to there is certain interval between messenger and oven body 1 and hot melt seal material 28.
On the other hand, as shown in fig. 1 and fig. 2, in the present application, since the hot-melt seal material 28 is disposed at the upper end of the counterbore 27, and since the diameter of the upper end of the counterbore 27 is larger than the diameter of the lower end of the counterbore 27, the hot-melt seal material 28 can be prevented from being pressed out of the counterbore 27 by the flame-retardant particles 24 in a cured state.
The specific theory of operation of this application is as follows, when oven body 1 takes place to catch fire, because the characteristic of flame, flame can stretch towards oven body 1's top, when flame is enough close to fire prevention mechanism 2's bottom, flame can melt the hot melt sealing material 28 in counter bore 27, the fire-retardant granule 24 that is located the second cavity this moment can fall out the second cavity through counter bore 27, fire-retardant granule 24 can put out some or all flames at the in-process that drops, when fire-retardant granule 24 in the second cavity reduces gradually, fire-retardant granule 24 no longer can support sealing plug 23, this moment because water has been put in the first cavity, water bottom pressure is higher, when sealing plug 23 loses the back of supporting, water in the first cavity 26 can rush out first cavity 26 and vaporize, thereby carry out the secondary fire extinguishing.
On the other hand, because the oven is usually that oven body 1 side fire is great when catching fire, consequently this application sets up conical second guide plate 29 in second chamber bottom, carry out the water conservancy diversion to fire-retardant granule 24 and water through second guide plate 29, thereby make water and fire-retardant granule 24 flow to oven body 1 side as far as possible, still can contact first guide plate 11 when water flows to oven body 1 side, water falls through vertical through-hole 12 on first guide plate 11 this moment, thereby form the water curtain around oven body 1, can prevent the fire to spread even eliminate the fire source better.
This application is through setting up fire prevention mechanism 2, through 28 high temperature melting's of hot melt seal material characteristic, thereby when taking place to catch fire at oven body 1, fire-retardant granule 24 drops in following the second cavity and once puts out a fire to the oven, furthermore, through the water in the first cavity 26, can carry out the secondary to the oven after fire-retardant granule 24 drops, and can form the water curtain in oven body periphery through setting up first guide plate and second guide plate, can prevent better that the fire source from stretching, this application simple structure, can block the fire source at the very first time and eliminate even, the security of production has greatly been improved.
On the basis, the hot-melt sealing material 28 is a hot-melt material with a melting point of 100-300 ℃, and specifically, the hot-melt sealing material 28 can be made of ABS, PET, PU or PP.
The flame-retardant particles 24 are silicon dioxide which is easy to obtain, good in thermal stability and easy to extinguish flames.
On the basis of the above, the bottom of the oven body 1 is further provided with wheels (not shown in the figure) to facilitate better movement of the oven body 1.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
