Abstract
Description
Technical Field
[0001] This utility model relates to the field of lubricating oil filtration technology, and in particular to a raw material filtration mechanism for lubricating oil production. Background Technology
[0002] In the lubricant production process, the filtration of raw materials is a crucial step in ensuring product quality. Lubricant base oils and additives often contain impurities such as solid particles. If these are not effectively removed, they will directly affect the purity, viscosity, and performance of the lubricant.
[0003] In the prior art, the filtration device for lubricating oil generally adopts a fixed filter screen structure. During the filtration process, impurities easily accumulate on the surface of the filter screen to form a filter cake layer, which not only reduces the filtration efficiency, but also causes the filter screen to break due to the increase in pressure difference. Furthermore, cleaning the filter cake layer formed by the accumulation of impurities requires manual cleaning by stopping the machine, which seriously affects the ability of continuous production. In order to solve the above problems, this application proposes a raw material filtration mechanism for lubricating oil production. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a raw material filtration mechanism for lubricating oil production. By integrating stirring blades and a conveying cylinder within the filter box, continuous mixing and filtration operations are achieved. A reciprocating screw mechanism driven by a synchronous belt drives a brush plate to reciprocate and scrape the bottom of the filter screen. Combined with the continuous slag discharge function of the spiral conveying blades, automatic screen cleaning without stopping the machine is achieved, thus solving the problem of filter screen clogging.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A raw material filtration mechanism for lubricating oil production includes a filter box. A motor is fixedly connected to the side wall of the filter box, and a transmission rod is fixedly connected to the output end of the motor.

[0009] Preferably, a driving pulley is fixedly connected to the outer wall of the transmission rod, and a driven pulley is fixedly connected to the outer wall of the rotating rod. The outer walls of the driving pulley and the driven pulley are jointly fitted with a first synchronous belt.
[0010] Preferably, a first pulley is fixedly connected to the outer wall of the rotating rod, and a second pulley is fixedly connected to the outer wall of the reciprocating screw. The outer walls of the first pulley and the second pulley are together fitted with a second synchronous belt.

[0012] Compared with the prior art, the advantages of this utility model are as follows:
[0013] 1. The motor output drives the transmission rod and multiple stirring blades to rotate, and the rotation of the multiple stirring blades can agitate the liquid and make it evenly mixed.
[0014] 2. The liquid can be filtered through the filter screen. The rotation of the transmission rod drives the first synchronous belt, the rotating rod and the spiral conveyor blades to rotate. The rotation of the spiral conveyor blades can transport impurities and finally discharge them through the port on the left.
[0015] 3. The rotating rod drives the second synchronous belt and reciprocating screw to rotate, causing the brush plate and brush to slide on the sliding rod. The brush can clean the bottom of the filter screen, thus cleaning the filter screen and preventing it from becoming clogged.
[0016] In summary, by integrating stirring blades and conveying cylinders within the filter box, continuous mixing and filtration operations are achieved. A reciprocating screw mechanism driven by a synchronous belt drives the brush plate to reciprocate and scrape the bottom of the filter screen. Combined with the continuous slag discharge function of the spiral conveying blades, automatic screen cleaning without stopping the machine is achieved, solving the problem of filter screen clogging.
