Abstract
The invention discloses an observation hole device on a kiln head cover, comprising a kiln head cover casing (2). The inner side of the kiln head cover casing (2) is provided with a lining (1) made of a refractory material, a communicated observation hole is arranged on the kiln head cover casing (2) and a board surface of the lining (1) made of the refractory material, the observation hole is internally provided with a bell-mouthed brick blocking ring (3) made of a high temperature-resistant metal material, the outer surface of the brick blocking ring (3) is provided with an observation hole seat (4), and the observation hole seat (4) is linked with an observation hole cover (5). The observation hole device is installed at a hole position and plays a role in effectively protecting the lining made of the refractory material and prolonging the service life of the same. By adopting the shapes of the brick blocking ring, the observation hole seat and other parts disclosed by the invention, the lining made of the refractory material can not be easily damaged, and an observation operation is facilitated after the observation hole device is installed.
Description
Technical field
The present invention relates to the fiery peep hole device of seeing on a kind of kiln head cover of carbon element rotary kiln.
Background technology
The kiln hood of common rotary kiln, production process is carried out at high temperature with in rotating.Burner and burning required air enter kiln through kiln head cover.Kiln head cover is also to see that firer people carries out the place of production operation, so kiln head cover is provided with peephole and access door.Kiln hood cylindrical shell and kiln hood cover body have inner lining refractory; the cover body that is opened in kiln head cover for the peephole of observing is positive; through refractory lining; but the plate of refractory lining is looked like fruit perforate; just weakened the intensity of liner, and open surface is coarse also easily falls piece, therefore must be provided with check ring for blocking bricks device; play protection and fixing refractory lining, in applied at elevated temperature process, can watch and grasp combustion position again.And the check ring for blocking bricks using at present cannot effectively be protected refractory lining, the service life of its liner is still undesirable.
Summary of the invention
Technical problem to be solved by this invention is, provides on a kind of kiln head cover with the peep hole device of check ring for blocking bricks, and this device can effectively be protected refractory lining, increases the service life of liner.
Technical scheme of the present invention: in order to solve the problems of the technologies described above, the present invention has adopted following technical scheme, this peep hole device comprises kiln head cover housing, inner side at kiln head cover housing is provided with refractory lining, on the plate face of kiln head cover housing and refractory lining, offer the peep hole being communicated with, in peep hole, be provided with the check ring for blocking bricks of the bell mouth shape that refractory metal material makes, at the outer surface of check ring for blocking bricks, peep hole seat be installed, on peep hole seat, be connected with handhole cover.
Described peep hole seat is connected in the outer surface of check ring for blocking bricks by screw bolt and nut.
Described peep hole seat is thin edge, thick middle, and mid portion is calabash shaped, and the gradient in its cross section is greater than 0 degree, is less than 180 degree.
The lower end of described handhole cover is connected on peep hole seat by lifting bolt.
Described handhole cover is calabash shaped, matches with the mid portion of peep hole seat.
Described screw bolt and nut is arranged on the edge of peep hole seat.
The present invention is arranged on tapping by peep hole device, has played the effect of effective protection refractory lining, has extended the service life of refractory lining.And adopt the shape of the parts such as check ring for blocking bricks of the present invention, peep hole seat, and further guaranteed that refractory lining is not easily damaged, and installed, be more conducive to the operation of observing.
Accompanying drawing explanation
Fig. 1 is the structural representation of whole kiln head cover of the present invention;
Fig. 2 is the K-K face structural representation of Fig. 1;
Fig. 3 is that the A of Fig. 2 is to structural representation.
The specific embodiment
Embodiments of the invention 1: as Figure 1-3, peep hole device of the present invention comprises kiln head cover housing 2, in the inner side of kiln head cover housing 2, be provided with refractory lining 1, on the plate face of kiln head cover housing 2 and refractory lining 1, offer the peep hole being communicated with, for the refractory lining 1 in hole has been opened in protection, in peep hole, be provided with the check ring for blocking bricks 3 of the bell mouth shape that refractory metal material makes, outer surface at check ring for blocking bricks 3 is connected with peep hole seat 4 by bolt 6 and nut 7, the thin edge of peep hole seat 4, be used for bolt 6 and nut 7, its thick middle, be calabash shaped, the gradient in its cross section is greater than 0 degree, be less than 180 degree, be that cross section has certain gradient.On peep hole seat 4, be connected with the lageniform handhole cover 5 that shape and peep hole seat 4 adapt, handhole cover 5 is connected on peep hole seat 4 with lifting bolt 8 by its lower end.
In the time of need to watching the duration and degree of heating, with long hook hook, open lifting bolt 8, turn an angle and just can conveniently watch combustion position.
