Description

Technical Field

[0001] The utility model relates to the technical field of incinerators, in particular to a fire viewing device and an incinerator. Background Art

[0002] The incinerator has very strict requirements on flame when working. Only when the flame reaches the preset value can the garbage be put in to ensure rapid, complete and efficient incineration.

[0032] Working principle:

[0033] Disassembling the fire-viewing mirror 3: control the sliding of the limit ring 7 to compress the elastic part 9 (compression spring). At this time, the inside of the limit ring 7 is no longer located outside the positioning hole 5, that is, it will no longer abut the positioning pin 6. At this time, the staff pulls the mounting ring 4 again to control the mounting ring 4 to slide along the axial direction of the fire-viewing tube 2. At this time, under the action of force, the positioning pin 6 slides radially along the fire-viewing tube 2, and the arc-shaped abutting end head at the lower end of the positioning pin 6 disengages from the arc-shaped positioning groove, so that the mounting ring 4 can be taken out from the mounting groove, and then the fire-viewing mirror 3 can be removed from the mounting groove. That is, the staff only needs to perform three steps in this operation: control the sliding of the limit ring 7, take out the mounting ring 4, and take out the fire-viewing mirror 3. The operation is simple and the disassembly is convenient.

[0034] Installing the fire-viewing mirror 3: When replacing and installing a new fire-viewing mirror 3 after removing the fire-viewing mirror 3, first put the new fire-viewing mirror 3 into the installation groove at a preset angle, then install the installation ring 4, control the installation ring 4 to slide into the installation groove along the axial direction of the fire-viewing tube 2, and make the installation ring 4 finally abut against the edge end of the fire-viewing mirror 3, when the installation ring 4 slides to the preset position, control each of the positioning holes 5 to be aligned with each of the positioning grooves respectively; then loosen the limit ring 7, and at this time the limit ring 7 is reset under the action of the elastic member 9, and the limit ring The inclined surface 10 on one side of 7 first presses against the end of the positioning pin 6 located in the sliding groove 8. At this time, the positioning pin 6 in the positioning hole 5 is forced to slide toward the inside of the fire-viewing tube 2 in the positioning hole 5 until the other end of the positioning pin 6 slides into the positioning groove. At the same time, the limit ring 7 is completely reset, and its inner wall is located at the outlet end of the positioning hole 5 and presses against the positioning pin 6 to limit the positioning pin 6 from sliding out toward the outer wall of the fire-viewing tube 2. At this time, the positioning pin 6 fixes the mounting ring 4, thereby realizing the installation of the fire-viewing mirror 3, and the installation method is simple and convenient.

[0035] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the utility model.
