Description

Technical Field

[0001] The utility model relates to the technical field of dust ash smelting, in particular to a gas collecting hood for dust ash smelting. Background Art

[0002] Dust ash will produce flue gas during recycling and smelting. A gas collecting hood is needed to collect the flue gas. However, the existing gas collecting hood is generally welded to the pipeline. It is not convenient to replace the gas collecting hood when it is damaged, which affects the work efficiency. In addition, the air inlet end of the existing gas collecting hood is of a certain length and cannot be adjusted, which affects the gas collection effect. Utility Model Content

[0003] The utility model aims to provide a dust collecting hood for ash smelting, which is used to solve the problems mentioned in the prior art in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an air collecting hood for dust ash smelting, comprising an air collecting hood body, the interface end of the air collecting hood body is provided with a quick-release assembly, the air inlet end of the air collecting hood body is provided with an extension assembly, the quick-release assembly comprises a quick-release tube and a sleeve arranged on the quick-release tube and slidingly matched with the quick-release tube, the quick-release tube is connected to the interface end of the air collecting hood body, the quick-release tube is sleeved with a slidable slide cylinder, the end of the quick-release tube is provided with a positioning cylinder, the side wall of the sleeve is slidably matched with a limit rod, the limit rod is sleeved with a spring, the two ends of the spring are respectively connected to one end of the limit rod and the sleeve, the slide cylinder and the positioning cylinder are both truncated cone-shaped and arranged relatively to each other, the other end of the limit rod is provided with a slope and the slope direction is the same as that of the positioning cylinder.

[0005] Furthermore, the extension assembly includes an extension ring arranged at the air inlet end of the air collecting hood body and an outer ring slidable on the extension ring.

[0006] Furthermore, a connecting pipe is provided on the quick-release pipe.

[0007] Furthermore, a sealing ring is provided on the lower bottom surface of the positioning cylinder.

[0008] Furthermore, an adjusting rod is hinged on the extension ring, and the adjusting rod cooperates with the outer ring thread.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] The utility model has the following beneficial effects:

[0011] The sleeve is moved downward, so that the other end of the limit rod is moved by the compressive force, causing the spring to contract. After sliding over the positioning tube, the spring stretches and drives the limit rod to move, thereby clamping the sleeve on the quick-release tube. When disassembling, the sleeve continues to slide downward. When the sleeve contacts the bottom surface of the slide tube, it is forced to contract until it slides to the side wall position of the slide tube and then moves upward. Under the action of the spring, the limit rod clamps the slide tube and drives the slide tube to move upward. When it moves upward to the sealing ring, the slide tube is reset under the action of gravity, and the sleeve continues to slide upward to complete the disassembly;

[0012] When the length of the air inlet end of the air hood body needs to be extended, the adjusting rod is rotated to drive the outer ring to move, thereby completing the adjustment of the length of the air inlet end of the air hood body;

[0013] The device realizes rapid installation and disassembly of the hood body through a quick-release assembly to prevent the hood from being inconvenient to replace when damaged, thereby affecting work efficiency. The length of the air inlet end of the hood body is adjusted through an extension assembly to facilitate more accurate collection of flue gas, thereby improving the gas collection effect.
