Abstract
The foam production special microwave foaming furnace that this utility model provides comprises housing and inner chamber, is furnished with magnetron (8) at cavity inner wall, at the cavity top or the side have air outlet (5), described air outlet (5) is connected with the cooling, air discharging system.The cooling of its unique magnetron and microwave foaming furnace exhaust system and parts except that the technological requirement that satisfies melamine foam production, have realized that more effectively the discharge of volatile matter in the cooling of magnetron and the foaming process microwave foaming furnace focuses on.
Description
Technical field
The utility model relates to microwave heating equipment, particularly a kind of industrial microwave foaming furnace of producing foamed plastics that is specifically designed to.
Background technology
Utilize microwave as the energy at present, can realize communication, food processing, disinfection, drying etc., but utilize the microwave manufacturing as the energy in the foamed plastics industry, report seldom.The small microwave stove is applied in family and fires food, industrial microwave oven is applied in sterilization and dry field, most of power is very little, at several hectowatts to tens kilowatt, and the form of utilizing rotating disk or motion makes the object homogeneous heating, industrial microwave oven is the single tube source that utilizes power bigger, methods for cooling is a water-cooled, system is comparatively complicated huge, the energize of be unfavorable for uniformly, concentrating, and this in addition microwave is supplied with form, be that the waveguide that utilizes transmits, be easy to take place echo, damage microwave source, the microwave inhibitor must be arranged.The flexible operation degree is not enough in addition, elder generation's preheating during start, the incompatibility application that heats up in a short period of time.The incompatible technological requirement of making foamed plastics of these microwave ovens.The technological requirement of foamed plastics is: (1), power are big, and energize is concentrated, more than 100 kilowatts; (2), a large amount of waste gas generations, the good vented exhaust passage of needs are arranged; (3), power is realized from zero to maximum step-less adjustment.(4), need not rotating disk and telecontrol equipment and realize that microwave density evenly distributes, the temperature rise difference that each several part can the field adds hot water is no more than ± 2 ℃.(5) foaming is to carry out in the short time, and it is fast that the intermittent type microwave foaming furnace must satisfy startup, and the time that reaches operate as normal will lack.Such microwave foaming furnace has two kinds of forms, and a kind of is box type furnace, and a kind of is continuous tunnel furnace.The cooling of common little microwave tube is to utilize a pipe one fan, and it is big that cooling device occupies the space, complicated various, safeguards very difficulty, is unfavorable for the centralized arrangement microwave tube.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of foam production special microwave foaming furnace, comprise housing and inner chamber, be furnished with magnetron at cavity inner wall, has air outlet at cavity top or side, air outlet is connected with the cooling, air discharging system, and the cooling, air discharging system comprises air channel and blower fan.Magnetron can assume diamond in shape in the arrangement of cavity inner wall, triangle, square or trapezoidal, and the heating position of magnetron is positioned at outside, and heating position is equipped with fan housing, and fan housing has air inlet.
The utility model utilizes cooling, air discharging system cools magnetron and cooling air is sent in stove, carrier gas as exhaust-gas treatment, cooling and exhaust-gas treatment have been realized simultaneously, multiple spot distribution microwave source makes even microwave distribution, help stepless control, realized the purpose of industrialized utilization microwave manufacturing foamed plastics.
Description of drawings
Fig. 1 is a cavity inner wall magnetron distribution map of the present utility model;
Fig. 2 is the utility model cooling, air discharging system schematic.
Embodiment
Referring to Fig. 1, the installation and design of the magnetron 8 of microwave foaming furnace is the centralized arrangement of the wall all around magnetron 8 in the microwave foaming furnace inside cavity, and magnetron 8 is arranged in rhombus, triangle, square or trapezoidal, the purpose of doing like this is to make even microwave distribution.Replace powerful single microwave source with little microwave tube, calculating under the situation about allowing, according to the situation of difference use power, arrange the magnetron 8 of varying number, just concentrate multiple spot to arrange the density of magnetron 8, guarantee the requirement of microwave density, in order to guarantee microwave density, magnetron 8 adopts direct feed-in, has removed expander, the complexity that minimizing equipment is installed has reached centralized control.Utilize control circuit with small magnetron tube high-pressure section separation adjusting, realize the step-less adjustment of microwave, toggle speed is fast like this, and adjustable range is wide, is more conducive to the suitability for industrialized production operation.
As shown in Figure 2, magnetron 8 can produce high temperature in that the negative electrode resonant cavity is local in when work, if cooling preferably can not cause the damage of magnetron; In addition, can produce a large amount of waste gas in process of production, therefore, the utility model at the cavity top or the side set out air port 5, air outlet 5 is connected with the cooling, air discharging system, the cooling, air discharging system comprises air channel 2 and blower fan 1; The heating position of magnetron 8 is placed the body of heater outside, guiding fan housing 7 is installed on the cooling fin of heating position, fan housing 7 has air inlet 6, when blower fan 1 work, cool exterior air is cooled off the heating position of magnetron earlier by the air inlet 6 of fan housing 7, enter cavity then, mix with the waste gas that produces in the production process, and from air outlet 5 discharges, the magnetron cooling and the microwave foaming furnace exhaust system of this uniqueness, except that the technological requirement that satisfies melamine foamed plastic production, the discharge of volatile matter focuses in more effective cooling that has realized magnetron and the foaming process microwave foaming furnace, save the energy, reduced the noise of complete machine, be convenient to focusing on of waste gas.
What may be obvious that for the person of ordinary skill of the art, draws other advantages and modification.Therefore, the utility model is not limited to shown and described specifying and exemplary embodiment here.Under the situation of the spirit and scope that do not break away from the utility model design, to its various modifications of making all in the protection range of claim.
