Description

Technical Field

[0001] This utility model relates to the field of hydraulic oil production, and in particular to a dust-free mixing vessel for the production of flame-retardant hydraulic fluids. Background Technology

[0002] Hydraulic oil is a crucial component of hydraulic systems, transmitting static pressure energy, lubricating the system, and also providing rust and corrosion protection, as well as cooling. The reliable, sensitive, accurate, efficient, and economical operation of a hydraulic system is closely related to the type and performance of the hydraulic oil. Therefore, a good hydraulic oil must possess the following properties: suitable viscosity and good viscosity-temperature characteristics; low compressibility; excellent extreme pressure anti-wear properties; good stability; good anti-foaming and air release properties; good filterability; and good compatibility with sealing materials. With the increasing complexity and sophistication of components in advanced hydraulic equipment, more stringent requirements are being placed on the quality of anti-wear hydraulic oils. Developing a high-performance, versatile anti-wear hydraulic oil for ease of use, maintenance, and upkeep has become a key focus of future research. Anti-wear hydraulic oils require the use of appropriate reaction and blending reactors for preparation.

[0003] In the prior art, Chinese utility model patent application with patent number 202022261919.X discloses a blending kettle for producing anti-wear hydraulic oil, including a base and a movable groove. The movable groove is opened inside the base, and a gasket is placed at the bottom of the movable groove. A guide column is slidably connected inside the movable groove. A connecting plate is fixedly connected to the upper end of the guide column. A platform is fixedly connected to the upper end of the connecting plate. A support leg is welded to the upper end of the platform. A blending kettle is welded to the upper end of the support leg. A kettle cover is threadedly connected to the upper end of the blending kettle.

[0004] However, the blending kettle in the above patent uses a filter screen to filter the materials in the blending kettle so that impurities are trapped by the filter screen. However, since the filter screen is installed in the blending kettle, when replacing the filter screen, it is necessary to open the kettle lid and remove and install the filter screen in the blending kettle. Removing and installing the filter screen in the blending kettle is very inconvenient and time-consuming, which will delay the production of the blending kettle. Utility Model Content
