Abstract
The utility model discloses a vertical type vacuum brazing furnace feeding device which comprises a furnace body and a heater strip. A furnace body baseplate is arranged inside the furnace body. A long screw is connected with the furnace body baseplate through a thread. Three layers of heat insulation screens are arranged on the long screw from top to bottom and are locked with each other through bolts. The vertical type vacuum brazing furnace feeding device is characterized in that four layers of feeding trays are arranged on the heat insulation screen arranged at the top layer through a supporting column; the feeding tray arranged at the bottom layer is corresponding to the position of the heater strip; a plurality of heat conduction holes are uniformly formed in the three layers of feeding trays from top to bottom. Heat can flow mutually through the heat conduction holes, so that uniformity of the temperature inside the furnace can be effectively guaranteed. By lowering the height form the furnace body baseplate to the feeding tray arranged at bottom layer and increasing a layer of feeding tray, the four layers of feeding tray can be placed at a heating zone, so that energy using rate can be improved and effective using rate of the feeding quantity of a vacuum brazing furnace can be improved by one third.
Description
Technical field
The utility model relates to the vertical vacuum soldering oven feeding device used in a kind of vacuum switch tube production process.
Background technology
In the vacuum switch tube production process, need to adopt vacuum brazing furnace by the vacuum switch tube tube core, the parts of moved end tube core and quiet end tube core carry out vacuum brazing, during operation, tube core is placed on feeding device, described feeding device comprises body of heater, inboard wall of furnace body is established heater strip, be provided with furnace body chassis in body of heater, be threaded connection on furnace body chassis long bolt is installed, three layers of heat screen and three layers of charging pallet are set from the bottom to top on long bolt, every layer of heat screen is to be folded to fall to forming by three thermal insulation boards, on long bolt, between corresponding furnace body chassis and bottom thermal insulation board and between adjacent thermal insulation board, be set with fixedly spacer and and by nut check, between top layer heat screen and bed charge pallet and adjacent charging pallet, a plurality of support columns are set.Described furnace body chassis is positioned at body of heater heater strip top, and the heat between bed charge pallet and top layer heat screen has been wasted, and these heats increase the weight of again the loss of heat screen simultaneously.
The utility model content
The utility model is to solve the problems referred to above that prior art exists, and a kind of inner space that takes full advantage of is provided, and prevents energy waste, improves the vertical vacuum soldering oven feeding device of charging area and charge.
The utility model is achieved in that
A kind of vertical vacuum soldering oven feeding device, comprise body of heater, inboard wall of furnace body is established heater strip, be provided with furnace body chassis in body of heater, be threaded connection on furnace body chassis long bolt is installed, three layers of heat screen are set from the bottom to top on long bolt also by nut check, its special character is: on the top layer heat screen, by support column, four layers of charging pallet are set, bottom charging pallet is corresponding with the heater strip position, on three layers of charging pallet from top to bottom, is evenly distributed with a plurality of thermal holes.
The diameter of described thermal hole is 20～30 mm.
The utility model has the advantages that: by thermal hole, heat can be flowed mutually, can effectively guarantee the uniformity of temperature in stove, in guaranteeing stove under the inhomogeneity prerequisite of temperature, by furnace body chassis to the height of bed charge pallet being reduced and increases one deck charging pallet, make four layers of charging pallet all be positioned at the thermal treatment zone, thereby the raising energy utilization rate, can effectively improve the charging area, make the charge effective rate of utilization of vacuum brazing furnace improve 1/3.
