Abstract
The utility model relates to a peephole of an industrial furnace. The peephole comprises a hole and a hole cover arranged on the hole, wherein the section of the hole is circular, the surface of the hole is an inclined surface, and an included angle between the inclined surface and the longitudinal perpendicular surface is 8-30 degrees; and a connecting rod is arranged at the upper end of the hole, and the hole cover is sleeved on the connecting rod. According to the utility model, the hole has the circular section and evenly expands at high temperature, and the phenomena, such as cracking and damage of the hole caused by uneven expansion by heating of the original rectangular hole, are effectively overcome. The peephole is made of cast steel ZG270-500 and has the capabilities of having outstanding heat-resistant and anti-deformation effects in the high temperature environment and favorable toughness and effectively prolonging the service life. Meanwhile, improvements that an operation mode of the hole cover is changed into a left-right swinging mode from an up-down flip manner, and the like, are made, so that the service life of the peephole is effectively prolonged, the maintenance rate of the peephole is reduced, and finally, the defects of the original peephole are fundamentally overcome. The peephole disclosed by the utility model has the advantages of low investment, good benefits and easy mounting, operation and maintenance.
Description
Technical field
The utility model relates to the industrial furnace technical field, specifically a kind of industrial furnace peep-hole.
Background technology
Industrial Stoves are in industrial production, utilize the heat of fuel combustion or electric energy conversion, with the Thermal Equipment of material or workpiece heating.The creation of Industrial Stoves and development play a very important role human progress.All be provided with peep-hole on the Industrial Stoves that use at present, but peep-hole mostly is square structure, material is cast iron, and mode of operation be cover-lifting type up and down, and the peep-hole of this structure in use easily deforms, operates the faults such as damage and high temperature scaling loss.
The utility model content
Technical problem to be solved in the utility model provides industrial furnace peep-hole a kind of simple and reasonable for structure, easy to use.
Adopt following technical scheme for solving technical problem of the present utility model:
A kind of industrial furnace peep-hole comprises hole and the port lid that is arranged on the hole, and the cross section in described hole is circular, the surface in described hole is an inclined-plane, the right angle of described inclined-plane and longitudinal vertical plane is 8 o-30o, and the upper end in described hole arranges a connecting rod, is set with port lid on the described connecting rod.
The material of described hole and port lid is cast steel ZG270-500.
The cross section of the utility model mesopore is circular, and the hot conditions thermal expansion is even, has effectively overcome former slot expanded by heating inhomogeneous and cause the phenomenon such as hole cracking damage.The material of selecting is cast steel ZG270-500, can be heat-resisting in hot environment, resistance to deformation is remarkably productive, and have good toughness, effectively prolonged its service life.Simultaneously the mode of operation of port lid is changed into the improvement of the aspects such as formula of vacillating now to the left, now to the right by cover-lifting type up and down, effectively prolonged the service life of peep-hole, reduced its maintenance rate, finally fundamentally solved the defective that former peep-hole exists.The utlity model has small investment, profitable, and be easy to install, the advantage of operation and maintenance.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cutaway view of Fig. 1;
Among the figure: 2-port lid, the 3-connecting rod of 1-hole.
The specific embodiment
Be described in further detail of the present utility model below in conjunction with accompanying drawing:
As shown in Figure 1, 2, a kind of industrial furnace peep-hole comprises hole and the port lid that is arranged on the hole, and the material of hole 1 and port lid 2 is cast steel ZG270-500.The cross section in hole 1 is circular, and the surface in hole 1 is an inclined-plane, and the right angle of inclined-plane and longitudinal vertical plane is 8 o-30o.The upper end in hole 1 arranges a connecting rod 3, and port lid 2 is sleeved on the connecting rod 3, realizes the function of port lid 2 move left and right.
During use, the utility model is installed in that industrial furnace need to be observed and the position of safety.When need observing, with the bar of certain-length port lid 2 is pushed aside along left and right directions and to be got final product, observe complete after, regain bar, port lid 2 will lean on action of gravitation automatically to fall, even exist in the situation of malleation in the stove, because the surface in hole 1 is an inclined-plane, port lid 2 relies on gravity also can realize shutoff.
Claims (2)
