Description

Technical Field

[0001] The invention relates to the technical field of reactor slag removal, in particular to a robot for removing slag inside a chemical reactor. Background Art

[0002] The working principle of a chemical reactor is to fully mix and contact the reactants in a relatively closed reactor body through a stirring device, and to cause a chemical reaction under appropriate temperature, pressure and other conditions. For example, in the field of petrochemicals, reactors are used in the refining process of crude oil, such as hydrocracking reactions. In a hydrocracking reactor, by adding hydrogen, under the action of high temperature, high pressure and catalysts, large molecular hydrocarbon compounds are cracked into small molecular hydrocarbons, thereby increasing the yield of light oil products such as gasoline and diesel.

[0003] In the prior art, a large amount of catalyst residue is generated after each production cycle of a chemical reactor. The residue needs to be cleared in time before the reactor can be used again normally. However, due to the narrow inlet of the reactor, the current method of removing the chemical residue inside the reactor is mostly done manually, but there are many problems. First, the air circulation inside the reactor is not smooth, and the construction workers need to carry oxygen supply equipment to remove the residue, which is very inconvenient during work; secondly, the working surface inside the reactor is limited, which is not conducive to large-scale manual operations, and the efficiency of excavation is very low.

After the slag in the range is broken, the No. 4 motor is started to drive the No. 2 screw rod to rotate, so that the adjustment block drives the breaking knife to move to expand the diameter of the circumferential breaking range circle.
