Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary maintenance devices for large metallurgical nozzles, in particular to a fixing and disassembling device for a back-blowing nozzle. Background Art
[0002] The backflush nozzle is a device designed to remove dust, powder or other deposits accumulated on the inner surface of filters, pipes or other equipment. It is widely used in many industrial fields, including but not limited to air purification, powder conveying, cement production, flue gas desulfurization system of coal-fired power plants, etc. Its working principle and characteristics are as follows:
[0003] 1. Compressed air / gas supply: The backflush nozzle generates a strong airflow through the instantaneous release of high-pressure air or gas (such as nitrogen).
[0004] 2. Directional impact: This high-speed airflow impacts the filter medium or the inner wall of the pipe at a precise angle and force, so that the dust or particles deposited on it are subjected to reverse impact force and detached from the original attached surface.
[0005] 3. Pulse cleaning: In applications such as bag dust collectors, backflush nozzles usually work in a set sequence and time interval to pulse clean each filter bag or filter unit in turn to maintain continuous and efficient filtration effects.
[0006] Design Features High Efficiency: Designed to provide concentrated energy release to effectively remove deposits even in confined spaces. Durability: Typically made of wear-resistant materials such as stainless steel or special alloys to adapt to high temperature, corrosive or abrasive environments. Adjustability: Nozzle angle, airflow velocity and spray pattern can be adjusted to achieve optimal cleaning results based on specific application needs. Energy Saving: Reduce unnecessary energy consumption by precisely controlling the energy of each backflush. Easy Installation and Maintenance: Designed for quick installation and regular replacement, reducing equipment downtime. Backflush nozzles are an indispensable component in industrial cleaning and maintenance, ensuring equipment operating efficiency and extending service life by precisely and efficiently removing dust accumulation.
[0007] During the disassembly process of the back-blowing nozzle, the action should be gentle to avoid damaging the nozzle or the connecting parts. At present, it takes two people to disassemble the bolts of the back-blowing nozzle, one person manually fixes it, and the other uses two wrenches to disassemble it, which occupies a large number of people, has high labor intensity, and has low disassembly efficiency.
[0008] Therefore, there is an urgent need to design a back-blowing nozzle fixing and disassembly device to solve the problems of large number of personnel, high labor intensity and low disassembly efficiency during the disassembly and maintenance of the existing reverse nozzle.

The upper part of the nozzle body 2.3 is mounted on the upper mounting plate 2.1 by four bolts, and the lower part of the nozzle body 2.3 is mounted on the lower mounting plate 2.2 by four bolts.
[0028] A nut is threadedly connected on the bolt and on one side of the nozzle body 2.3. The upper part of the nozzle head 2.4 extends out of the upper mounting plate 2.1, and the lower part of the nozzle head 2.4 extends out of the lower mounting plate 2.2.

The vertical plate 1.3 is vertically fixed on one side of the bottom plate 1.2. The upper part of the vertical plate 1.3 is rotatably connected to the movable plate 1.1. The movable plate 1.1 and the bottom plate 1.2 limit the nozzle 2 by clamping. The movable plate 1.1 and the bottom plate 1.2 are both provided with bolt limiting holes 1.5. The positions of the bolt limiting holes 1.5 are adapted to the bolts installed above and below the nozzle 2. The bolts on the nozzle 2 enter the bolt limiting holes 1.5 to position the nozzle 2.
[0030] Four bolt limiting holes 1.5 are provided on the movable plate 1.1 and the bottom plate 1.2. The bolt limiting holes 1.5 are hexagonal holes consistent with the bolt caps of the bolts. The size of the bolt limiting holes 1.5 is larger than the size of the nut of the bolt. The bolt cap of the bolt extends into the bolt limiting holes 1.5 and limits rotation.
