Abstract
A preparation room with a heating device and for a three-room successive vacuum furnace belongs to the vacuum furnace technology field and comprises three heaters and a preparation room; the three heaters are respectively arranged on a left wall and a right wall and at the top of the preparation room; and every heater comprises a heat insulation screen, a fixing threaded rod, an armored heater, a pressing plate, a power supplying interface of the armored heater, a metal pipe and a thermocouple. Compared with the prior art, the preparation room with the heating device and for the three-room successive vacuum furnace has the advantages of greatly reducing the working time of a heating room by arranging the heating device in the preparation room to enable the temperature of a workpiece before entering the heating room to be increased to 300 DEG C from the room temperature, being basically uniform in the temperature of the preparation room, the heating room and a cooling room, reducing the working time of the heating room to be half of the original working time, improving 50% production efficiency of the three-room successive vacuum furnace, enabling the heating room to perform heating not only in a vacuum state but also in an atmosphere state by utilizing the stainless steel armored heater.
Description
Technical field
The utility model belongs to the vacuum drying oven technical field, particularly a kind of preparation room with heater for three Room continous vacuum furnace apparatus.
Background technology
At present, the preparation room of three Room continous vacuum furnace apparatus is only done vacuum exhaust, and heating clamber is only done heating in vacuum, and cooling chamber is only done quick cooling.The heating clamber working time is the longest in three vacuum chambers, approximately be preparation room, cooling chamber working time about 2 times, cause workpiece to be finished in the work of preparation room and cooling chamber, workpiece is not but finished in the work of heating clamber, preparation room and cooling chamber have to wait for the situation that heating clamber is finished, and do not give full play of the production efficiency of three Room continuous vacuum furnaces.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the defective that prior art exists, and provides a kind of working time that can shorten heating clamber, the preparation room with heater that also can heat under the atmospheric condition.
The technical solution adopted in the utility model, comprise 3 heaters and preparation room, 3 heaters are distributed in respectively the Zuo Bi of preparation room, right wall and top, and each heater includes heat screen, standing screw, sheathed heater, pressing plate, sheathed heater power supply interface, metal tube and thermometric idol; Heat screen, sheathed heater, pressing plate are fixed on the inwall of preparation room by standing screw, sheathed heater is snakelike layout at heat screen, heat screen is comprised of at least 2 layers of metallic plate, be provided with the gap between every layer of metallic plate, sheathed heater power supply interface and thermometric idol are installed in the preparation room outer wall, the sheathed heater power supply interface connects the outer power supply of preparation room, and metal tube side helical form is welded on the preparation room outer wall.
Described metal tube is copper pipe.
The utility model compared with prior art beneficial effect is: by increasing heater at preparation room, make workpiece enter the front temperature of heating clamber and be increased to 300 ℃ by room temperature, shortened greatly the working time of heating clamber, the working time of preparation room, heating clamber, cooling chamber is basically identical, make working time of heating clamber be reduced to original half, make like this production efficiency of three Room vacuum continuous furnaces improve 50%.Because what use is the stainless steel sheathed heater, and preparation room not only can be heated under vacuum state, also can heat under atmospheric condition.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the left view of Fig. 1;
Among the figure: 1 preparation room, 2 heat screens, 3 standing screws, 4 sheathed heaters, 5 pressing plates, 6 sheathed heater power supply interfaces, 7 copper pipes, 8 thermometrics idol.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As illustrated in fig. 1 and 2, this device comprises 3 heaters and preparation room 1,3 heaters are distributed in respectively the Zuo Bi of preparation room 1, right wall and top, and each heater includes heat screen 2, standing screw 3, sheathed heater 4, pressing plate 5, sheathed heater power supply interface 6, copper pipe 7 and thermometric idol 8; Heat screen 2, sheathed heater 4, pressing plate 5 are fixed on the inwall of preparation room 1 by standing screw 3, sheathed heater 4 is snakelike layout at heat screen 2, make preparation room 1 about and top all cover sheathed heater 4, heat screen 2 is comprised of 3 layers of corrosion resistant plate, arrange the thick spacer ring of 10mm between every layer of corrosion resistant plate, play the effect of insulation; Preparation room 1 outer power supply connects sheathed heater power supply interface 6, and thermometric idol 8 is installed in preparation room 1 outer wall, and the control of preparation room 1 interior temperature is controlled by thermometric idol 8, realizes at preparation room 1 interior accurate temperature controlling; For preventing that preparation room 1 outside wall temperature from raising, copper pipe 7 is welded on preparation room 1 outer wall in the shape of a spiral simultaneously, and security reserve chamber 1 outside wall temperature is not higher than 40 ℃.
