Description

Full-automatic large-scale tubular reformer/pyrolysis furnace boiler tube outer wall dust collector Technical Field The utility model relates to the technical field of converters in petrochemical industry, in particular to a full-automatic large-scale tubular converter/cracking furnace tube outer wall dust removal device. Background In the industries of petrochemical industry, coal chemical industry and the like, a full-automatic large-sized tubular reformer or a cracking furnace is used as core equipment to bear key process steps of raw material cracking, conversion and the like. In the running process, the radiant tube is in a high-temperature and high-load working condition for a long time, and impurities such as accumulated ash, coking and the like are easily adhered to the outer wall of the radiant tube. The attachments not only can reduce the heat transfer efficiency of the radiant tube and increase the energy consumption, but also can cause local overheating, accelerate the aging of the tube and even cause safety accidents such as tube explosion. The full-automatic large-scale tubular converter/pyrolysis furnace boiler tube outer wall dust collector among the prior art is when removing dust to large-scale tubular converter or pyrolysis furnace radiant tube outer wall, is all cleared up with the wire brush by many workman aloft work, and not only very dangerous, and efficiency is lower, and the practicality is relatively poor. Disclosure of utility model The utility model aims to solve the problems of high risk, low efficiency and poor practicability of cleaning by using steel wire brushes for high-altitude operation of a plurality of workers when the outer wall of a radiant tube of a large-scale tubular reformer or a cracking furnace is subjected to dust removal in the prior art, and provides a full-automatic dust removal device for the outer wall of a furnace tube of the large-scale tubular reformer/cracking furnace. In order to achieve the aim, the utility model adopts the following technical scheme that the full-automatic large-scale tubular converter/cracking furnace tube outer wall dust removal device comprises a furnace tube, wherein two sides of the furnace tube are respectively provided with two supporting blocks, a cradle head is arranged between the two groups of supporting blocks, telescopic steel wire brushes are arranged in the two cradle heads, two sides of the furnace tube are respectively provided with a bracket, and lifting wheel sets matched with the furnace tube are respectively arranged in the two brackets. Preferably, two opposite sides of the support are provided with fixing blocks, one opposite ends of the fixing blocks are provided with linear motors, and output ends of the linear motors penetrate through the two fixing blocks respectively and are fixed with the two supports respectively. Preferably, two groups of cloud platforms are fixed with connecting blocks at opposite ends, two connecting blocks are fixed with supporting columns at opposite ends, and the fixing blocks are arranged between the two supporting columns and fixed with the two supporting columns. Preferably, a plurality of steel wire rope cable hanging holes are formed in the supporting block. Preferably, a connecting plate is fixed on the outer wall of the bracket, and a locking mechanism is installed at one end of the connecting plate. Preferably, one end of each of the two connection blocks is commonly fixed with an outer cover. Compared with the prior art, the utility model has the advantages and positive effects that; According to the utility model, the two cradle heads are sleeved on the outer side of the furnace tube, at the moment, the two brackets are driven to move oppositely through the operation of the two linear motors, so that the two groups of lifting wheel sets are attached to the outer wall of the cradle head, an external steel wire rope is hung through a steel wire rope cable hanging hole, the whole device is driven to lift through the operation of the external steel wire rope, and meanwhile, the outer wall of the furnace tube can be automatically cleaned through the operation of the telescopic steel wire brush in the cradle head, manual cleaning is not needed, and the two groups of lifting wheel sets can be adjusted according to the width sizes of different furnace tubes through the operation of the linear motors, and on the other hand, the auxiliary limiting effect is achieved because the two groups of lifting wheel sets are attached to the furnace tube, so that the device can stably lift, and the practicability is stronger.
