Abstract
The invention relates to a furnace door rear sealing structure for a trolley gas thermal treatment furnace. The furnace door rear sealing structure comprises a contact seal block, a guide rod, a guide block and a furnace door affiliated fixing block which is fixed to the rear part of the furnace door, wherein the rear part of the contact seal block is fixedly connected with the guide rod; the guide rod is arranged on the guide block; the guide block is fixedly connected to the affiliated fixing block; a screw is arranged at the end of the guide rod; and a pretightening spring is arranged on the guide rod corresponding to the screw and is in butted connection with the other screw arranged on the guide rod. According to the furnace door rear sealing structure for the trolley gas thermal treatment furnace, pretightening force is applied to the contact seal block by the pretightening spring, so that the contact seal block contacts the rear part of the furnace door tightly to achieve a good sealing effect, prevent high-temperature gas inside the furnace body from leaking and ensure the using safety of the furnace body.
Description
Technical field
The present invention relates to sealed structure behind a kind of pallet car type combustion gas heat treatment furnace fire door, is the sealed structure of car-type heat treating furnace.
Background technology
Heat treatment furnace is the general designation of metal works being carried out the industrial furnace of various metal heat treatmets.Heat treatment furnace can adopt the type of furnace of various process furnace, but requires more strictly to control furnace temperature and furnace atmosphere etc.The most using gas fuel heating of heat treatment furnace, in order accurately to control furnace temperature, the heat treatment furnace that has is used electrically heated.Modern thermal treatment (particularly thermo-chemical treatment) technology is increasingly sophisticated, and the form of heat treatment furnace is also a lot.For successive thermal treatment flow process, must be equipped with suitable continuous heat treating furnace; For cycling thermal treatment process, operating machine and the robotization that adopt the CA controlled atmosphere of pump circulation and make stove.
Like the patent No. 200720040085 disclosed a kind of heat treatment furnace structures, purpose provides the less heat treatment furnace of a kind of floor space.It comprises solid solution stove, the aging oven that is provided with roller bar type e Foerderanlage; Quenching tank; And material is transported to the grass-hopper of aging oven from the solid solution stove through quenching tank, solid solution stove, aging oven are arranged up and down, and liftable grass-hopper is set below the end of solid solution stove; On the bottom surface of the solid solution stove above the grass-hopper, have with bottom surface and become the split type movable discharge door that is connected; The below of grass-hopper is a quenching tank; One side of quenching tank is an aging oven; Roller bar type e Foerderanlage is set on grass-hopper, and the roller rod on grass-hopper, solid solution stove, the aging oven parallels.
Because the fire door of pallet car type combustion gas heat treatment furnace needs often to open and close; The material of fire door and structure need be different with body of heater; Generally to the sealing requirements of fire door than higher; If the bad problem that will bring the dissipation of furnace high-temperature gas of sealing effectiveness, but above-mentioned patent does not solve the problem that the fire door of pallet car type combustion gas heat treatment furnace at high temperature seals.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, provide a kind of good seal performance pallet car type combustion gas heat treatment furnace fire door after sealed structure.
The objective of the invention is to realize through following technical scheme:
Sealed structure behind a kind of pallet car type combustion gas heat treatment furnace fire door; Comprise contact seal piece, tail rod, orienting lug and be fixed on the attached fixed block of fire door at fire door rear portion; The rear portion of said contact seal piece is fixedly connected with tail rod; Said tail rod is installed on the orienting lug, and orienting lug is fixedly connected on the attached fixed block; The end of said tail rod is equipped with screw, and corresponding said screw is equipped with preloading spring on tail rod, and said preloading spring holds out against with another screw on being installed in tail rod and is connected.
Sealed structure behind the pallet car type combustion gas heat treatment furnace fire door of the present invention; Through preloading spring said contact seal piece is applied preliminary tension; Can guarantee that the contact seal piece closely contacts with the rear portion of fire door; And then reach good sealing effectiveness, and prevent that the high-temperature gas of body of heater inside from revealing away, guarantee the security that body of heater uses.
Description of drawings
According to accompanying drawing and embodiment the present invention is done further explain below.
Fig. 1 is the structure iron of sealed structure behind the pallet car type combustion gas heat treatment furnace fire door according to the invention.
Embodiment
As shown in Figure 1; Sealed structure behind the described pallet car type combustion gas of the embodiment of the invention heat treatment furnace fire door; Comprise contact seal piece 1, tail rod 2, orienting lug 3 and be fixed on the attached fixed block 4 of fire door at fire door rear portion; The rear portion of said contact seal piece 1 is fixedly connected with tail rod 2, and said tail rod 2 is installed on the orienting lug 3, and orienting lug 3 is fixedly connected on the attached fixed block 4; The end of said tail rod 2 is equipped with screw 5, and corresponding said screw 5 is equipped with preloading spring 6 on tail rod 2, and said preloading spring 6 holds out against with another screw 7 on being installed in tail rod 2 and is connected.
Sealed structure behind the pallet car type combustion gas heat treatment furnace fire door of the present invention; Through preloading spring said contact seal piece is applied preliminary tension; Can guarantee that the contact seal piece closely contacts with the rear portion of fire door; And then reach good sealing effectiveness, and prevent that the high-temperature gas of body of heater inside from revealing away, guarantee the security that body of heater uses.
