Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of pharmaceutical preparation, and specifically relates to a reactor for preparing pharmaceuticals for removing titanium-containing coatings. Background Art
[0002] The agent for removing titanium-containing coatings is a specially developed chemical preparation used to efficiently and quickly remove titanium coatings from metal surfaces while ensuring that the substrate is not corroded. The ingredients of this agent have been carefully selected and formulated to undergo a specific chemical reaction with the titanium coating, thereby decomposing or dissolving it. First, it needs to be applied to the metal surface containing the titanium coating. After application, it is necessary to wait a certain amount of time for the agent to fully contact the coating and chemically react. During this time, the chemical components in the agent will interact with the titanium coating, causing the coating to gradually decompose or dissolve. Therefore, when removing titanium-containing coatings, these parameters must be strictly controlled to ensure that the agent can fully exert its efficacy while avoiding adverse effects on the metal substrate.
[0003] As a professional chemical reaction equipment, the reactor can provide the necessary reaction conditions and environment to ensure the smooth progress of the preparation process of the agent. In the reactor, various raw materials are mixed, heated, stirred and other steps to finally produce the agent for removing titanium-containing coatings.
[0004] Generally, after preparing the agent for removing the titanium-containing coating, the reactor is often scraped or flushed to wash away the residual agent on the inner wall of the reactor. This is because the agent for removing the titanium-containing coating is often highly corrosive and will affect the inner wall of the reactor if it adheres for a long time. The existing reactor inner wall cleaning device is often unable to effectively remove the residual agent attached to the inner wall of the reactor and the stirring shaft at the same time. For this purpose, a reactor for preparing the agent for removing the titanium-containing coating is provided. Utility Model Content

[0007] In a preferred embodiment, the stirring mechanism includes a stirring motor, a drive shaft and a stirring rod. The stirring motor is fixedly mounted on the top surface of the preparation reactor, the driving end of the stirring motor extends into the interior of the preparation reactor, the driving end of the stirring motor is fixedly mounted with a drive shaft, and the outer surface of the drive shaft is fixedly mounted with a stirring rod.

[0009] In a preferred embodiment, a pressure relief valve is fixedly installed on the top surface of the preparation reaction kettle.
[0010] In a preferred embodiment, a heat-insulating shell is fixedly installed on the outer surface of the preparation reactor, and a plurality of pillars are fixedly installed on the outer surface of the heat-insulating shell.
[0011] In a preferred embodiment, a drainage pipe is fixedly installed on the bottom surface of the preparation reaction kettle, and an electric-controlled valve is provided on the outer surface of the drainage pipe.

[0013] 1. In the present application, due to the adoption of the above-mentioned scheme, the operator starts the external liquid supply pump, so that the cleaning liquid flows into the interior of the inclined installation tube through the pipeline connection, the liquid supply tube and the circular pipeline and is sprayed out through the cleaning nozzle 1 and the cleaning nozzle 2, forming a liquid flow, which flows down along the inner wall and the stirring shaft of the preparation reactor.
