Abstract
The invention relates to a furnace door structure of a trolley gas thermal treatment furnace. The furnace door structure comprises a furnace door body which consists of a furnace door skeleton and a door plank, wherein the furnace door skeleton is in a square grid shape; two lateral surfaces of the furnace door skeleton are fixedly connected with the door plank respectively; two compacting arms which are arranged symmetrically are arranged on upper and lower edges of the furnace door body respectively and are screwed down by bolts; two tensioning arms which are arranged symmetrically are arranged on one lateral edge which is provided with a handle on the furnace door body; and pretightening springs are arranged on the tensioning arms to perform pre-compaction. According to the furnace door structure of the trolley gas thermal treatment furnace, the furnace door is compacted by the compacting arms, a sealing effect of the closed furnace door is good by the tensioning arms, and the furnace door skeleton can ensure that the furnace door has enough rigidity, so that the integral furnace door has high mechanical performance, and particularly has high tightness and capacity of deformation resistance at high temperature.
Description
Technical field
The present invention relates to a kind of door structure of pallet car type combustion gas heat treatment 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.
Traditional door structure and common door and window are as good as, so in order to guarantee the structural strength of fire door, particularly the intensity under hot environment just need be worked hard on the size of fire door, but the big more manufacturing cost of size is high more, use also just all the more inconvenient.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of door structure of simple in structure, pallet car type combustion gas heat treatment furnace that mechanical property is strong is provided.
The objective of the invention is to realize through following technical scheme:
A kind of door structure of pallet car type combustion gas heat treatment furnace; Comprise the oven door body that is made up of fire door skeleton and door-plate, said fire door skeleton is pattern, and two sides of fire door skeleton are fixedly connected with door-plate respectively; Be separately installed with the clamping arm of two symmetric arrangement on the both sides up and down of oven door body; Said clamping arm is tightened through bolt, and a side that on oven door body, is provided with handle is equipped with the tension arm of two symmetric arrangement, and said tension arm is provided with preloading spring and carries out precompressed.
The door structure of pallet car type combustion gas heat treatment furnace of the present invention; Through clamping arm fire door is compressed; Sealing effectiveness through straining after arm is closed fire door is better; And the fire door skeleton can guarantee that fire door has enough rigidity, so can guarantee that on the whole fire door has stronger mechanical property, the ability of stopping property under hot conditions and resistance to deformation particularly.
Said clamping arm adopts paired setting respectively with the tension arm, and the position symmetry, can guarantee the stress equalization of oven door body structure like this, guarantees sealing effectiveness and rigidity.
Description of drawings
According to accompanying drawing and embodiment the present invention is done further explain below.
Fig. 1 is the structure iron of the door structure of pallet car type combustion gas heat treatment furnace according to the invention.
Fig. 2 is the vertical view of the door structure of pallet car type combustion gas heat treatment furnace according to the invention;
Fig. 3 is the side-view of the door structure of pallet car type combustion gas heat treatment furnace according to the invention.
Embodiment
Shown in Fig. 1-3; The door structure of the described pallet car type combustion gas of embodiment of the invention heat treatment furnace; Comprise the oven door body that is made up of fire door skeleton 1 and door-plate 2, said fire door skeleton 1 is pattern, and two sides of fire door skeleton 1 are fixedly connected with door-plate 2 respectively; Be separately installed with the clamping arm 3 of two symmetric arrangement on the both sides up and down of oven door body; Saidly compress 3 and tighten through bolt 5, a side that on oven door body, is provided with handle is equipped with the tension arm 4 of two symmetric arrangement, and said tension arm 4 is provided with preloading spring 6 and carries out precompressed.
The door structure of pallet car type combustion gas heat treatment furnace of the present invention; Through clamping arm fire door is compressed; Sealing effectiveness through straining after arm is closed fire door is better; And the fire door skeleton can guarantee that fire door has enough rigidity, so can guarantee that on the whole fire door has stronger mechanical property, the ability of stopping property under hot conditions and resistance to deformation particularly.
