[0002] Hydraulic lubricating oil is a hydraulic medium used in hydraulic systems that utilize liquid pressure energy. It plays roles such as energy transfer, anti-wear, system lubrication, anti-corrosion, rust prevention, and cooling in the hydraulic system. The main components of hydraulic lubricating oil include base oil and various additives. The selection of the base oil needs to be adjusted according to different working conditions and environmental conditions, and the quality requirements include aspects such as viscosity, oxidation stability, low-temperature fluidity, foam inhibition, and anti-wear performance.

[0003] The production process of hydraulic oil mainly includes links such as quality inspection, stirring, heating, mixing, filtering, adjustment, and packaging of raw materials. Among them, stirring and heating are key technological links, and the control of temperature and stirring time needs to be well mastered.

[0004] Traditional stirring equipment for processing hydraulic lubricating oil pours the base oil and various additives of hydraulic lubricating oil into a reaction kettle, and drives the stirring rod and stirring blades to rotate through a motor to stir and blend the base oil and various additives in the reaction kettle.

[0005] However, the existing stirring equipment for processing hydraulic lubricating oil has problems such as a relatively high height of the reaction kettle, the need for auxiliary equipment to lift and pour the base oil and various additives, poor blending effect, and low working efficiency.

A feeding component for feeding hydraulic lubricating oil into the inner cavity of the base is arranged in the feeding pipe. An outlet pipe for sending the blended hydraulic lubricating oil out of the base is also provided on the base. A guiding groove communicating with the inner cavity of the base is opened at the bottom of the stirring cylinder. A blending component for sending the hydraulic lubricating oil entering the inner cavity of the base into the stirring cylinder through the guiding groove and blending the hydraulic lubricating oil is arranged in the inner cavity of the stirring cylinder. A plurality of discharging grooves communicating the inner cavity of the base and the inner cavity of the stirring cylinder are evenly opened on the lower side of the stirring cylinder.

[0007] To achieve the above object, the hydraulic lubricating oil entering the inner cavity of the feeding pipe is sent into the inner cavity of the base through the feeding assembly, without the need for other auxiliary lifting and tilting assemblies to cooperate. The power is provided by the mixing assembly, so that the hydraulic lubricating oil in the inner cavity of the base is sent into the inner cavity of the mixing drum through the guiding groove, and the hydraulic lubricating oil entering the inner cavity of the mixing drum is mixed. The mixed hydraulic lubricating oil falls back into the inner cavity of the base through the discharge groove.

The rotation of the feeding auger 15 drives the hydraulic lubricating oil entering the inner cavity of the feeding pipe 8 through the feeding hopper into the inner cavity of the base 2, realizing the feeding function.

[0040] Such as Figure 3 And Figure 4 And Figure 5 , The mixing assembly includes a guiding cylinder 20 arranged at the middle position of the inner cavity of the mixing drum 3. The guiding cylinder 20 is axially arranged. The inner cavity of the guiding cylinder 20 is hollow with openings at both the upper and lower ends. The upper and lower ends of the guiding cylinder 20 do not contact the top and bottom of the inner cavity of the mixing drum 3. The mixing drum 3 and the guiding cylinder 20 are fixed by a support frame 21 located on the lower side of the inner cavity of the mixing drum 3. A number of uniformly arranged guiding grooves 22 are provided on the support frame 21.

[0041] Such as Figure 3 And Figure 4 And Figure 5, a mixing rod 23 is rotatably connected to the middle position of the sealing cover 4. The mixing rod 23 penetrates through the inner cavity of the material guiding cylinder 20. The part of the mixing rod 23 that penetrates out of the inner cavity of the material guiding cylinder 20 passes through the stirring cylinder 3 through the guiding groove 11. The part of the mixing rod 23 that penetrates out of the inner cavity of the stirring cylinder 3 enters the inner cavity of the base 2.

[0042] As Figure 3 and Figure 4 and Figure 5 , power is provided by the mixing motor 24 to drive the rotation of the mixing rod 23 coaxially fixed to the output shaft of the mixing motor 24 and the mixing auger 25 coaxially fixed to the mixing rod 23. Through the rotation of the mixing auger 25, the hydraulic lubricating oil in the base 2 is driven to enter the inner cavity of the stirring barrel through the guiding groove 11 and into the material guiding cylinder 20. The hydraulic lubricating oil entering the material guiding cylinder 20 continues to move upward under the rotation of the mixing auger 25 until it is lifted to the top of the material guiding cylinder 20. The hydraulic lubricating oil is thrown out of the material guiding cylinder 20 in an umbrella shape to achieve the mixing of the hydraulic lubricating oil.

Then, the hydraulic lubricating oil is thrown out of the material guiding cylinder 20 in an umbrella shape to achieve the blending of the hydraulic lubricating oil. The blended hydraulic lubricating oil passes through the discharge groove 12 and penetrates out of the mixing cylinder 3 and enters the inner cavity of the base 2, or enters the inner cavity of the base 2 through the material guiding groove 22 and the guiding groove 11. The above operations are repeated to achieve the repeated blending of the hydraulic lubricating oil and improve the blending effect;

[0046] At the same time, the rotation of the blending rod 23 drives the rotation of the driven rod 26 and the scraper 27 having an integrated structure with the blending rod 23.
