Abstract
Disclosed is equipment using catalytic combustion heat energy for baking an enameled wire from the bottom. Firstly, a bottom baking box is additionally arranged at the bottom of a main furnace, and the enameled wire is baked by the aid of heat radiation of the baking box rather than circulating hot air containing particulates and is baked by the bottom baking box and the circulating hot air from the upper side and the lower side simultaneously, so that the drying speed of the enameled wire is increased. Moreover, a large amount of the circulating hot air is blown in from a rear area, and in the rear area, a film is formed on the surface of the enameled wire, so that the enameled wire is not easy to be eroded by the particulates in the circulating hot air. Compared with the prior art, by the aid of the additionally arranged bottom baking box, the baking speed of the enameled wire is increased by 12% averagely, saved electricity is increased by 16%, and emission standard is decreased below 30mg/m3, so that quality of enameled wire products is obviously enhanced.
Description
[technical field]
The utility model relates to enamelled wire and covers the equipment that paint film cures drying that is coated with, particularly utilize the enamelling machine equipment of the thermal energy to replace electric energy heating behind the catalytic combustion, relate in particular to and adopt the hot air mixing chamber that the catalytic combustion thermal energy reasonable distribution is arrived each zone of burner hearth, simultaneously take into account quality of enamelled wire again, reduce the equipment of discharge standard again.
[background technology]
In the prior art, energy-saving little line enamelled wire machine baker of some enamelled wire manufacturing firm research and development, catalytic combustor in its waste gas recycle device is arranged on burner hearth curing area one end, the gas that the enamelled wire solvent is evaporated burns through catalytic combustor, produce thermal current, burner hearth is squeezed in fresh air following current after the thermal current preheating, and energy-saving effect is not obvious.
For this reason, many producers undergo technological transformation to existing equipment successively, and some patents have been applied for, for example: Chinese utility model patent has been arranged No. 02290021.7, the technical scheme of disclosed a kind of " energy-saving little line enameling machine oven " by name, this utility model solution: a kind of energy-saving little line enameling machine oven, comprise burner hearth, waste gas recycle device, wherein, the inlet of waste gas recycle device is arranged on evaporating area one end of burner hearth, and outlet is connected with curing area one end of burner hearth by circulating fan, branch air channel.
Though the reverse burner hearth cavity of squeezing into of thermal current that this scheme reclaim to produce waste gas, single inlet is far away apart from the evaporating area of burner hearth, still needs the electrothermal tube heating in the evaporating area of burner hearth, and therefore, energy-saving effect does not reach ideal value.
Moreover this scheme just adapts to the little type of processing capacity, if every equipment is processed many enamelled wires simultaneously side by side, this device structure is just inapplicable.
No. 03263874.4 Chinese utility model patent for another example, the technical scheme of disclosed a kind of " two circular form horizontal enameling machine oven " by name, though this scheme is all squeezed into the thermal current that the waste gas recovery produces in the evaporating area and the curing area of burner hearth, but it does not still solve the problem of whole burner hearth reasonable distribution heat, the middle district that is to say burner hearth does not have the heat supply, still needs the electrothermal tube heating.
Simultaneously, this scheme does not think over the problem of quality of enamelled wire, that is to say the evaporating area of the burner hearth when the enamelled wire solvent is evaporated, be that enamelled wire is the easiest of the interval of particle contamination, quote the size issue that circulating air will consider that the amount of quoting is compared with fresh hot blast, and the problem between the area of coverage.
Also have, this scheme does not have to solve the problem that how further to reduce discharge standard.
In order to overcome the deficiencies in the prior art, the applicant has applied for the utility model patent of 200910105133.4 " a kind of method and apparatus of enamelling machine reasonable catalytic combustion thermal energy distribution ", in the technical scheme of this patent application, a hot air mixing chamber is assigned to the proparea of burner hearth, middle district and back zone with catalytic combustion thermal energy, and reasonable distribution is to the heat in each district, thereby accelerated the progress of curing, improved production efficiency 20%.
Owing to the waste gas that is trapped in the dead angle is collected and the quadric catalysis burning, and circulating air is carried out catalytic combustion repeatedly one time, make discharge standard reduce to 50mg/m
3Below, be significantly less than national 120mg/m
3Standard.
Because just stopped using main stove heating tube in more than one hour that brings into operation at equipment, and the catalytic combustion thermal energy of migrating, so this technology can be saved the electric energy more than 30%.
But this technology still has deficiency, that is: the Lower Half of the enamelled wire deficiency of being heated, and it is irregular to cause whole enamelled wire to be heated, and its physical aspect is undesirable.
Because too much catalytic combustion thermal energy directly contacts with enamelled wire, its particulate that includes causes the smoothness on enamelled wire surface to be affected in addition.
Also irregular owing to being heated, cause the enamelled wire speed of service further not improve.
[utility model content]
