The utility model also comprises a steel pipe welded into the hole of the hot plate as well as an electric heating pipe arranged in the steel pipe, liquid filled in a hole drilled on the lateral plates and vacuum pumped, and a taper pin for welding and sealing the liquid filling hole. The utility model has the advantages of saving energy, reducing heat loss, improving the accuracy of the temperature difference of the plate, and the utility model is suitable for a plate vulcanization machine.
Description
The utility model relates to a kind of vulcanizing press vacuum hot plate that is applied to vulcanizing press.
The employed hot plate of existing vulcanizing press is a solid construction, because heat conduction thickness is big, for improving heat transfer property, need to reduce heat conduction thickness, this just has in whole hot plate and drains into several electrothermal tubes, but electrothermal tube quantity is many more, and power consumption is also many more, and has more heat to be dispersed in the air, thermal losses is big, in addition, when hot plate reached design temperature, the hot plate working surface temperature difference also was not very little, be about ± 5 ℃, but for rubber industry, the temperature difference is the smaller the better, this hot plate is difficult to reach ± and 1 ℃ high-precision requirement.
The purpose of this utility model is to provide the vulcanizing press vacuum hot plate of a kind of conserve energy, reduction thermal losses, the reduction temperature difference.
In order to achieve the above object, the utility model vulcanizing press vacuum hot plate is by flat board, electrothermal tube is formed, its special character is, said flat board comprise by about two blocks of side plates, the two blocks of side plates in front and back, internal face not only had gradient but also be distributed with some in the hot plate pressurized process base plate of passive back-up block and the square box that cover plate is welded, the steel pipe that welds in the hole of on the relative biside plate of the bigger end of box bottom skew wall face and cover plate internal face distance, being bored, vacuumize the heat transfer property better fluid medium that charged into of back in the hole of being bored on the side plate in office, be welded into being used for the Cone pin in the topping up hole behind the topping up the airtight Cheng Rongti of vacuum hot plate; Said electrothermal tube is installed in the dull and stereotyped steel pipe.
The vulcanizing press vacuum hot plate that the utility model proposed owing to be hollow airtight appearance body structure, in diabatic process, exists heat convection and conduction process simultaneously.So-called heat convection is meant that the vacuum hot plate holds fluid mobile in the body under the effect of the continuous heating of electrothermal tube, with heat from the high zone-transfer of temperature to the low zone of temperature, in airtight appearance body heat plate, owing to vacuumize, eliminated the existing adverse effect of heat convection of cross-ventilation body, in addition, in the utility model vulcanizing press vacuum hot plate, if the hot plate internal face is not with gradient, then under the effect of internal difference in temperature driving force, free convection is accelerated, too much heat transferred on the terminal side plate, by side plate heat conduction, heat is lost in the air, obviously, on, when following internal face is straight wall, heat transfer situation is bad, and after the utility model adds gradient for an internal face, in Convective Heat Transfer, the skew wall face plays a part gradually, and slowing down fluid conducts heat, terminal side plate internal face at heat convection will form turbulent boundary layer, and the heat transport fluid micelle is in the motion of making a return journey on the internal face direction up and down perpendicular to hot plate, and the boundary layer VELOCITY DISTRIBUTION is even, and fluid can be along on the hot plate, following internal face forms circulation, thereby concentrate touring heating hot plate working surface, homogeneous heating, thermal losses is few.The conduction process here is meant that mainly heat passes to the process of outside wall surface from the internal face of sealing appearance body heat plate, compare with common solid hot plate, heat-conducting area enlarges markedly, heat conduction thickness has also reduced, so heat flow increases, heat transfer rate is fast, homogeneous heating, from the above mentioned as can be known, the utility model vacuum hot plate good heat-transfer, thermal losses is low, when reaching the design temperature of vacuum hot plate heating, and the working surface temperature difference (5), again because the minimizing of heat conduction thickness, heat-conducting area increases, and has reduced heating and has used electrothermal tube quantity, can save energy 60%～65%.
Below with reference to embodiment and accompanying drawing thereof the utility model is done further explanation.
Figure one is a vulcanizing press hot plate structural representation of the prior art.
The vulcanizing press vacuum hot plate structure front view that figure two is in the present embodiment to be proposed.
Figure three is side views of figure two
In figure one, vulcanizing press is made up of dull and stereotyped (1) and electrothermal tube (2), even six holes stem for stem on whole flat board (1), and put into the electrothermal tube (2) of six heating usefulness respectively.
In figure two, figure three, the vulcanizing press vacuum hot plate that present embodiment proposed also is by dull and stereotyped (1), and electrothermal tube (2) is formed; Said flat board (1) comprise by about two blocks of side plates (1
1), the two blocks of side plates (1 in front and back
2), internal face not only had gradient but also be distributed with some in the hot plate pressurized process base plate (1 of passive back-up block
3) and cover plate (1
4) square box that is welded, two side plates (1 about the casing front end
1) on be welded with two steel pipes (1 side by side in the hole of being bored
5), at back side panel (1
2) on vacuumize the heat transfer property better fluid medium (1 that the back is charged in the hole of being bored
6), be welded into being used in the topping up hole behind the topping up with the Cone of the airtight Cheng Rongti of vacuum hot plate pin (1
