Embodiment Construction

[0013] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0014] Such as Figure 1~2 As shown, the present invention mainly includes a peeking tube 1 and a peeping cover 2, and the end surface of one side of the peeping tube 1 is connected to the peeping cover 2 through a connecting bolt 3 . The peeping tube 1 is provided with a through peeping hole 6 , and the peeping cover 2 completely blocks one side of the peeping hole 6 .

[0015] The connecting bolt 3 is connected with a locking nut 4, the locking nut 4 can lock the peeping tube 1 and the peeping cover 2, and a gasket 5 is arranged between the locking nut 4 and the peeping cover 2.

[0016] The edges of the two ends of the peep cover 2 are large and small arc structures, and the inner side of the larger end of the peep cover 2 is provided with a circular accommodation groove 7. During installation, the accommodation groove 7 faces the peephole, and the...

Abstract

The invention relates to a heating furnace, in particular to a heating-furnace spying cylinder assembly, and belongs to the technical field of heating furnaces. The heating-furnace spying cylinder assembly comprises a spying pipe and a spying cover, the end face of one side of the spying pipe is connected with the spying cover through a connecting bolt, a through spying hole is formed in the spying pipe, and one side of the spying hole is completely covered with the spying cover. The edges of the two ends of the spying cover are of a large arc structure and a small arc structure, and a protruding arc-shaped rotational lug plate is arranged on the outer side of the large end of the spying cover. The heating-furnace spying cylinder assembly is simple, compact and reasonable in structure, stable and reliable in work and low in cost; the spying hole of a furnace body can be protected, the conditions in a furnace can be clearly spied for a long time accordingly, and the service life of the spying hole is prolonged.

Description

technical field [0001] The invention relates to a heating furnace, in particular to a heating furnace viewing cylinder assembly, which belongs to the technical field of heating furnaces. Background technique [0002] In the prior art, industrial heating furnaces are widely used in the metallurgical industry and the refining industry. In order to observe the situation in the furnace body, a peephole is generally set on the furnace body, and a heat-insulating glass is set in the peephole. Observe the condition of the furnace. After long-term use, dust is easy to form on the heat-insulating glass, which leads to blurred vision, and it is impossible to observe the situation in the furnace well, and the heat-insulating glass cannot be easily replaced, which affects the normal use of the galvanizing furnace. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a heating furnace peeping cylinder assembl...
