Technical field

The utility model relates to tunnel furnace apparatus, and in particular to a kind of novel smooth film softening and regular tunnel furnace door knot Structure.

Background technique

Continuous tunnel furnace (food processing class) is that the tunnel type machinery for completing food-baking by the conduction of heat, convection current, radiation is set It is standby.The oven body is generally very long, 6 meters minimum, long to 60~80 meters.Baking vessel is a long and narrow tunnel, and width is generally 80cm to 140cm.There is the transportation system continuously run in tunnel.When food baking, food by transporting chain plate, steel band or Relative motion is generated between mesh belt and heating element or direct combustion burner, to complete the work uniformly toasted and conveyed.The tunnel Road furnace is mainly used for the food enterprise of industrialized production, characterized by high volume accomplished continuously or intermittently toasting.But it is general at present Continuous tunnel furnace is inconvenient when using and operating, and perfect can not guarantee its good inside because of the bulky of continuous tunnel furnace Environment.

Utility model content

In view of the problems of the existing technology, the utility model provides a kind of novel smooth film softening and regular tunnel furnace door Structure.

The technical solution of the utility model is:

A kind of novel smooth film softening and regular continuous tunnel furnace door structure, including fire door, doorframe and sealing element, the fire door peace Loaded on the outside of continuous tunnel furnace；The doorframe is connected with tunnel furnace internal-lining and shell；The sealing element between liner and doorframe, It seals to fire door and liner.

Preferably, the fire door includes fire door wall and handle of fire gate, the handle of fire gate is mounted on fire door wall, for opening Close fire door.

Preferably, the doorframe includes doorframe inner edge and the outer iron of doorframe, doorframe inner edge one end is fixed on liner, not One end is fixed with shell；The outer iron of the doorframe includes frame and hinge, and the hinge is connected with fire door；The outer iron of the doorframe and door Frame inner edge is fixed on together on tunnel stove outer covering.

Preferably, having observation window on the fire door wall, the operating condition in observation window to continuous tunnel furnace can pass through；The fire door Pars intramuralis is fixed with hinge fixing seat and handle fixed base, and furnace wall surface corresponding thereto has processing hole for installing firedoor handle Hand and hinge.

Preferably, the sealing element is silicone-rubber seals, sealing contact surface has arc convex.

Using the technical solution of the utility model, have the advantages that

1, product quality is promoted: isolation furnace inner environment and external environment, prevents the entrance of foreign matter to product quality It influences.There is provided a relatively stably and controllable warm and humid environment, for product softening, it is regular a best operating condition is provided, Be conducive to Improving The Quality of Products；

2, energy-saving: while completely cutting off furnace inner environment and external environment, to also counteract that the outside of heat scatters and disappears, more Using the mode that circulating-heating is blown, same in-furnace temperature is maintained, the energy of required consumption is less, the thermal efficiency of complete machine It is higher, and the stability of temperature is higher, is more nearly isoperibol.

Specific embodiment

Below in conjunction with the drawings and specific embodiments, the present invention will be further described.

Referring to figs. 1 to Fig. 5, the utility model provides a kind of novel smooth film softening and regular continuous tunnel furnace door structure, including Fire door 1, doorframe 2 and sealing element 3, the fire door 1 are installed on the outside of continuous tunnel furnace；The doorframe 2 and tunnel furnace internal-lining and outer shell phase Connection；The sealing element 3 seals to fire door 1 and liner between liner and doorframe 2.

The fire door 1 includes fire door wall 11 and handle of fire gate 12, and the handle of fire gate 12 is mounted on fire door wall 11, is used for Switch fire door 1.

The doorframe 2 includes doorframe inner edge 21 and the outer iron 22 of doorframe, and described 21 one end of doorframe inner edge is fixed on liner, not One end is fixed with shell；The outer iron 22 of the doorframe includes frame 221 and hinge 222, and the hinge 222 is connected with fire door 1；It is described The outer iron 22 of doorframe is fixed on tunnel stove outer covering together with doorframe inner edge 21.

There is observation window 112 on the fire door wall 11, can pass through the operating condition in observation window 112 to continuous tunnel furnace；The furnace It is fixed with hinge fixing seat 111 and handle fixed base 113 inside door wall 11, furnace wall surface corresponding thereto has processing hole to be used for Handle of fire gate 12 and hinge 222 are installed.

The sealing element 3 is silicone-rubber seals, and sealing contact surface has arc convex.

Utility model works principle are as follows: in continuous tunnel furnace operation, handle of fire gate 12 is fixed on fire door wall, fire door 1 with The outer iron 221 of doorframe is linked together by hinge 222, and the outer iron 221 of doorframe is fixed on continuous tunnel furnace with 21 one end of doorframe inner edge jointly On shell；21 other end of doorframe inner edge is fixed with liner, is fixed with sealing element 3 therebetween, when continuous tunnel furnace works normally, fire door knot Structure is closed, and the pressure in 1 outside of fire door is applied to by the locking mechanism on the outside of continuous tunnel furnace, is contacted on the inside of fire door wall with sealing element 3, Sealing element 3 generates flexible deformation, achievees the effect that sealing.

The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model, Under all utility models in the utility model are conceived, equivalent structure made based on the specification and figures of the utility model Transformation, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
