Abstract
The utility model is related to a kind of deep coolings to be tempered all-in-one oven, including furnace body, liner, heating element, liquid nitrogen delivery system, it is characterized in that the heating element is heating rod, it is to be made of heater strip and external stainless steel sealing shroud, heating rod is arranged on the inside of liner, and is distributed at a certain distance along the internal perisporium of liner.Its main feature is that：Heating rod is set inside the liner of furnace body, not only the efficiency of heating surface is high, saves electric energy, and heater strip will not be influenced frosting and corrosion by liquid nitrogen, ensure the service life of heating rod, substantially increases the reliability of all-in-one oven, heating rod it is easy for assemble or unload, convenient for safeguarding.
Description
Technical field
The utility model is related to a kind of heat treatment quenching equipment, particularly a kind of deep cooling tempering all-in-one oven.
Background technology
Deep cooling tempering all-in-one oven can carry out subzero treatment and temper to workpiece, realize a stove and complete at twice
Science and engineering sequence, saves equipment and space, without transporting work pieces, simplifies manual operation.Tempering and deep cooling two are completed in stove
Procedure the problem is that：To workpiece carry out subzero treatment when, under the action of liquid nitrogen, heating element easily occur frosting and
Corrosion reduces the service life of heating element.Solution to this problem is to arrange heating element i.e. heater strip at present
Outside stove liner, although will not be influenced by liquid nitrogen, the thermal efficiency is reduced, installation, the dismounting of heater strip are not square enough
Just, maintenance difficult.
Invention content
A kind of deep cooling the purpose of this utility model is to provide dependable performance, thermal efficiency height, component service life length returns
Fiery all-in-one oven.
The technical solution of the utility model is：A kind of deep cooling is tempered all-in-one oven, including furnace body, liner, heating element,
Liquid nitrogen delivery system, it is characterised in that the heating element is heating rod, is by heater strip and external stainless steel sealing shroud structure
Into heating rod is arranged on the inside of liner, and is distributed at a certain distance along the internal perisporium of liner.
The utility model is characterized in that：Heating rod is set inside the liner of furnace body, and not only the efficiency of heating surface is high, saves electricity
Can, heater strip peripheral hardware stainless steel sealing shroud, heater strip will not be influenced frosting and corrosion by liquid nitrogen, and ensure heating rod uses the longevity
Life, substantially increases the reliability of all-in-one oven, heating rod it is easy for assemble or unload, convenient for safeguarding.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the sectional view along A-A of Fig. 1.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1, 2, deep cooling, which is tempered in all-in-one oven 1, is provided with stainless steel inner container 2, and the section of furnace body and liner is circle
Shape, material SUS304, using Seal Design, liner is welded on furnace body.The present embodiment uses 6 heating rods 3, and heating rod is
It is stretched in furnace body liner from furnace body side, heating rod terminals are fixed on furnace body, and fire end is located inside liner, and 6 add
Hot pin is equally distributed along the internal perisporium of liner at a certain distance.Heating rod is by heater strip and external stainless steel sealing shroud
It forms, heater strip can be effectively prevent to be corroded when deep cooling heats.In order to make liquid nitrogen and uniformity of temperature profile in stove, inside
Courage is internally provided with ventilating duct 5, and work piece platform 4 is arranged in ventilating duct 5, and 9 bottom end of pillar being connected with work piece platform passes through
Ventilating duct, liner are fixed on furnace body.Be open at opposite position with ventilating duct and be provided with Gas Stirring fan 6, with mounted on
Motor 7 outside furnace body connects, and by forming circulated air in ventilating duct, in-furnace temperature is made to be more evenly distributed.Liquid nitrogen by into
Liquid mouth outer tube 8 enters furnace body liner.Furnace body other structures are same as the prior art, repeat no more.
