Description

Technical Field

[0001] This utility model belongs to the technical field of lubricating oil production equipment, and relates to a mixing kettle feeding device. Background Technology

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and machinery to reduce friction and protect machinery and processed parts. Its main functions include lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering. Any product used between two relatively moving objects to reduce friction and wear caused by contact is considered lubricating oil. The production of lubricating oil requires a blending reactor for mixing and a feeding device for adding the base oil. In the lubricating oil blending process, the blending reactor is a key piece of equipment, requiring precise mixing of base oil and various additives according to the formula ratio.

[0003] According to the inspection institute, Chinese patent CN219186613U discloses a feeding device for a lubricating oil blending kettle, including a blending kettle body and a feeding pipe. The feeding pipe is provided on the upper end face of the blending kettle body, and an adjusting pipe is installed on the outer wall of the feeding pipe. The adjusting pipe is arranged inside the blending kettle body. A screening chamber is arranged on the outer wall of the adjusting pipe through a connecting frame. Multiple screening holes are provided on the outer wall of the screening chamber. A fixing frame is installed on the upper end face of the blending kettle body, and an adjusting cylinder is installed at the top of the fixing frame. The output end of the adjusting cylinder is connected to the outer wall of the adjusting pipe through an L-shaped frame. In this utility model, the screening chamber is used to screen impurities in the raw materials, so that the processed lubricating oil has a better appearance and higher quality. At the same time, the sliding fit adjusting pipe structure is adopted to avoid the raw materials falling too high from the bottom of the blending kettle during the feeding process, which would cause the raw materials to splash and adhere to the inner wall of the blending kettle, resulting in material waste. When the device is in use, the feed pipe and feed branch pipe lack corresponding preheating devices and sealing structures. Paste additives are prone to stagnation and blockage on the inner wall of the conveying pipe, resulting in uneven feeding. High-viscosity raw materials have poor flowability and are unevenly dispersed after entering the mixing tank, affecting product quality. Some additives are easy to volatilize or deteriorate after contact with air. The device's insufficient airtightness leads to raw material loss and environmental pollution.

[0004] Therefore, this utility model provides a mixing kettle feeding device to solve the above problems. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model discloses a mixing tank feeding device. The technical solution adopted is as follows: It includes a mixing tank, which comprises a mixing vessel extending from the bottom to the right support leg and a top cover with an opening at the top of the mixing vessel. A discharge pipe with an electromagnetic valve is fixedly installed at the center of the bottom of the mixing vessel. A support frame is installed on the upper part of the top cover. A lubricating oil inlet pipe is opened on the right side of the top cover. A pump is installed on the lubricating oil inlet pipe. A spiral conveying pipe is horizontally arranged on the upper part of the support frame. The device is equipped with spiral blades. The right end of the shaft of the spiral blades extends to the outside of the spiral conveying pipe and is connected to a drive motor. The upper inlet of the right end of the spiral conveying pipe is connected to the lower inlet of the raw material storage hopper. The left end of the spiral conveying pipe is connected to the upper end of the vertical discharge pipe through an elbow. A jacketed heater is fixedly installed in the middle of the vertical discharge pipe. The inlet and outlet of the jacketed heater are located on the upper and lower sides of the vertical discharge pipe, respectively. The lower end of the vertical discharge pipe is inserted through the left edge of the upper cover.

[0006] As a preferred embodiment of this utility model, the center of the upper cover is provided with a stirring element extending into the tank body. The stirring element includes a stirring shaft and stirring teeth arranged in a circumferential array from top to bottom on the stirring shaft. The stirring teeth are inclined downwards at an angle of 45-70 degrees with the stirring shaft. The top of the stirring element is driven by a motor mounted on the upper cover. By using a motor to drive the stirring element to rotate, the raw materials in the mixing tank can be fully mixed. At the same time, the downward-inclined design of the stirring teeth allows the liquid on the stirring teeth to slide off quickly after mixing, reducing stagnation.

[0007] As a preferred embodiment of this utility model, hemispherical protrusions are evenly distributed on the inner wall of the spiral conveying pipe, and the height of the hemispherical protrusions is 3-5mm; by using protrusions, it is easy to match with the spiral blades, so that the agglomerated solid powder is quickly broken up.

[0008] As a preferred embodiment of this utility model, a sealing cover is provided on the top of the raw material storage hopper, and a transparent observation window is opened on the upper part of the sealing cover; by using a sealing cover, the raw material in the raw material storage hopper is isolated from contact with the outside world.

[0009] As a preferred embodiment of this utility model, an inert gas inlet pipe is provided on the edge of the cover on the left side of the transparent observation window; by introducing inert gas through the inert gas inlet pipe, air is further isolated to prevent volatile or oxidizable raw materials from coming into contact with air.

[0010] As a preferred embodiment of this utility model, the inner wall of the raw material storage hopper is provided with a removable polytetrafluoroethylene (PTFE) liner, the thickness of which is 5-8 mm; by using the PTFE liner, the raw materials are prevented from adhering.

[0011] The beneficial effects of this utility model are: the combination of spiral conveying and jacket heating solves the problem of conveying high-viscosity raw materials and avoids blockage; the inert gas protection system prevents the raw materials from oxidizing and volatilizing, reducing losses and pollution; and the polytetrafluoroethylene inner liner can be disassembled and cleaned, reducing maintenance costs.
