Description

Technical Field

[0001] The utility model relates to the technical field of waste lubricating oil processing, in particular to a pretreatment device for waste lubricating oil. Background Art

[0002] Lubricating oil is a liquid lubricant used in various types of machinery to reduce friction and protect machinery and workpieces. It mainly plays the role of lubrication, cooling, rust prevention, cleaning, sealing and buffering. Lubricants are easily oxidized and emulsified after long-term use in machinery, and due to the wear of mechanical parts, they carry impurities mainly including mechanical debris. Therefore, lubricating oil needs to be replaced frequently. If the replaced lubricating oil is directly discarded without treatment, it will cause heavy metal pollution, which is not conducive to environmental protection. Therefore, waste lubricating oil needs to be processed and recycled.

[0003] In the process of pre-treatment and filtering impurities of general waste lubricating oil, the waste lubricating oil often becomes viscous due to emulsification, resulting in slow filtration, and the horizontal filter mesh is easily clogged, which further reduces the filtration efficiency. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the utility model provides a waste lubricating oil pretreatment device, which can effectively solve the problem of low filtration efficiency of the existing waste lubricating oil.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] The utility model provides a waste lubricating oil pretreatment device, comprising a body, a bellows fixedly inserted on the body, a filter fixedly installed in the body, a cleaning brush for cleaning the filter, and a displacement assembly for controlling the dislocation movement of the bellows and the cleaning brush.

[0007] The displacement assembly includes a screw rod rotatably mounted in the body, a sliding seat slidably mounted on the screw rod, a rotation control block rotatably mounted on the sliding seat, a guide rod fixedly inserted on the rotation control block, and ball seats slidably inserted at both ends of the guide rod;

[0008] A group of limit rods are respectively provided above the cleaning brush and on one side of the bellows, and a sliding block is provided on the sliding sleeve of the limit rod. The two groups of sliding blocks are used to restrain the movement of the cleaning brush and the bellows respectively. A fixed ring block is fixedly installed on the bellows, and the fixed ring block is rotatably connected to a group of ball seats. The fixed ring block is fixedly connected to a group of sliding blocks, and the other group of ball seats is rotatably connected to the sliding block.

[0009] Furthermore, a limit block is fixedly connected to the cleaning brush, a locking block is rotatably installed in the limit block, a connecting rod is fixedly installed on the locking block, and the connecting rod is fixedly connected to a set of sliding blocks.

[0010] Furthermore, four groups of positioning grooves are symmetrically provided on the locking block, wherein the angle between adjacent positioning grooves on the same side is 60 degrees.

[0011] Furthermore, two groups of fixing grooves are symmetrically provided in the limit block, springs are fixedly installed in the fixing grooves, and the ends of the springs are fixedly connected with latches.

[0012] Furthermore, the filter screen is inclined at 30 degrees relative to the horizontal plane.

[0013] Furthermore, the connecting rod is L-shaped to match the inclination angle of the filter screen.

[0014] Furthermore, two groups of push rods are symmetrically fixedly installed on the inner wall of the machine body.

[0015] Furthermore, a debris collecting box is fixedly installed on the surface of the machine body and on both sides of the lower side of the filter screen.

[0016] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example: Refer to the attached Figure 1 —Attachment Figure 5 As shown, a pretreatment device for waste lubricating oil includes a body 1, on which a bellows 2 is fixedly inserted, and the bellows 2 is connected to an oil tank for storing waste lubricating oil. The bellows 2 has certain foldability and elasticity due to its characteristics, which is convenient for reciprocating movement to dump the waste lubricating oil. A filter 101 is fixedly installed in the body 1, and the filter 101 is used to filter impurities entrained in the waste lubricating oil. The filter 101 is inclined 30 degrees relative to the horizontal plane. Unlike the generally horizontally placed filter, the filter 101 with a certain inclination angle helps the waste lubricating oil to flow thereon. The waste lubricating oil is filtered during the flow, and the filtered impurities are retained on the grid. Even if the mesh of the filter 101 is blocked, the flowing waste lubricating oil can still be filtered out from other grids through which it flows. A collection box 103 is fixedly installed on the surface of the body 1 and on both sides of the lower side of the filter 101. The impurities remaining from the filtration will be pushed into the collection box 103 for collection and treatment.

[0028] A cleaning brush 301 for cleaning the filter 101 is provided in the body 1. The cleaning brush 301 that swings back and forth on the filter 101 can clean impurities on the grid of the filter 101. During the displacement process, the impurities on the grid will slide to the lower side of the filter 101 as the cleaning brush 301 pushes it. The filter 101 with an inclined angle has a certain temporary storage function. When there is a certain amount of impurities to be removed in the filter 101, the cleaning brush 301 will push it to the collection box 103. A displacement component 4 for controlling the dislocation movement of the bellows 2 and the cleaning brush 301 is also provided in the body 1. By setting the displacement component 4, the relative dislocation movement of the bellows 2 and the cleaning brush 301 is controlled, giving the waste lubricating oil a certain flow filtration time, and at the same time, the filter 101 can be cleaned in time.

[0029] Specifically, the displacement assembly 4 includes a screw rod 401 rotatably installed in the body 1, and a forward and reverse motor for driving the screw rod 401 to rotate is provided on the body 1. The screw rod 401 drives the sliding seat 4011 to move back and forth along it, and a sliding seat 4011 is slidably installed on the screw rod 401. A rotation control block 4012 is rotatably installed on the sliding seat 4011. The rotation control block 4012 drives the guide rod 4013 to slide back and forth on the limit rod 402. A guide rod 4013 is fixedly inserted on the rotation control block 4012. The guide rod 4013 is used to control the dislocation movement of the cleaning brush 301 and the bellows 2. Ball seats 4014 are slidably inserted at both ends of the guide rod 4013. By setting the ball seat 4014, the guide rod 4013 can be swung and turned while controlling the movement of the connecting rod 3 and the fixed ring block 201.

[0030] Furthermore, a group of limit rods 402 are respectively provided above the cleaning brush 301 and on one side of the bellows 2. The limit rods 402 are used to limit the moving trajectory of the connecting rod 3 and the bellows 2 so that they can only move in a horizontal linear direction. A sliding sleeve is provided with a sliding block 403 on the limit rod 402. The two groups of sliding blocks 403 are used to restrain the movement of the cleaning brush 301 and the bellows 2 respectively. A fixed ring block 201 is fixedly installed on the bellows 2. The fixed ring block 201 is rotatably connected to a group of ball seats 4014. The fixed ring block 201 is fixedly connected to a group of sliding blocks 403. By providing the fixed ring block 201, the ball seat 4014 and the fixed ring block 201 can simultaneously control the movement of the bellows 2. Another group of ball seats 4014 and the sliding block 403 are rotatably connected. This group of ball seats 4014 and the sliding block 403 simultaneously control the movement of the cleaning brush 301.

[0031] When the cleaning brush 301 changes the cleaning direction, the limiting block 302 is fixedly connected to the cleaning brush 301, and the limiting block 302 wraps the locking block 303, so that the cleaning brush 301 and the connecting rod 3 can rotate relative to each other. The internal structure of the limiting block 302 can make the connecting rod 3 and the cleaning brush 301 have a certain relative locking effect. The locking block 303 is rotatably installed in the limiting block 302, and four groups of positioning grooves 3031 are symmetrically provided on the locking block 303. By setting the positioning grooves 3031, it is convenient to insert the latch 3022, and the relative rotation angle of the limiting block 302 and the locking block 303 is locked, wherein the angle between the adjacent positioning grooves 3031 on the same side is 60 degrees. By setting the relative The angle of the adjacent cleaning brush 301 is limited to limit the switching angle of the cleaning brush 301 after each rotation. When the oblique cleaning brush 301 cleans impurities on the filter 101, it can avoid the impurities from gathering and falling from top to bottom, causing excessive impurities to pass over the surface of the cleaning brush 301 and remain on the filter 101. A connecting rod 3 is fixedly installed on the locking block 303. The connecting rod 3 is L-shaped to match the inclination angle of the filter 101, and the connecting rod 3 is fixedly connected to a group of sliding blocks 403. By setting the connecting rod 3, the connecting rod 3 is connected to the displacement component 4 and drives the cleaning brush 301 to move. At the same time, the relative angle of the cleaning brush 301 can be locked by the locking block 303.

[0032] Specifically, two groups of fixing grooves are symmetrically opened in the limit block 302, and a spring 3021 is fixedly installed in the fixing groove. The spring 3021 pushes the pin 3022 to insert into the positioning groove 3031. The end of the spring 3021 is fixedly connected to the pin 3022. The pin 3022 inserted into the positioning groove 3031 can control the relative fixed position of the cleaning brush 301 and the locking block 303.

[0033] Furthermore, two sets of push rods 102 are symmetrically fixedly installed on the inner wall of the body 1. When the displacement component 4 controls the cleaning brush 301 to move close to the push rod 102, the displacement component 4 will continue to move to the same side of the push rod 102. The push rod 102 will change the cleaning angle of the cleaning brush 301 by pushing the cleaning brush 301, and make the lower part of the cleaning brush 301 push the accumulated impurities into the collection box 103.

[0034] Furthermore, the bellows 2 pours the waste lubricating oil into the filter 101 at the highest position of the filter 101, the forward and reverse motors are started, the screw 401 is controlled to rotate, and the sliding seat 4011 on the screw 401 moves back and forth on it, the sliding seat 4011 drives the guide rod 4013 to move horizontally through the rotation control block 4012, and the guide rod 4013 drives the connecting rod 3 and the fixed ring block 201 to slide relative to each other through the ball seat 4014 and the sliding block 403, so that the bellows 2 and the cleaning brush 301 are misaligned for filtering and cleaning; the filter 101 filters the waste lubricating oil, and the cleaning brush 301 swings back and forth on the filter 101 to clean impurities on the grid of the filter 101. When the displacement component 4 controls the cleaning brush 301 to move close to the push rod 102, the displacement component 4 will continue to move to the same side of the push rod 102. The push rod 102 pushes the cleaning brush 301, so that the pin 3022 in the upper limit block 302 of the cleaning brush 301 moves from one group of positioning grooves 3031 to the positioning groove 3031 on the adjacent side, changing the cleaning angle of the cleaning brush 301 and allowing the lower part of the cleaning brush 301 to push the accumulated impurities into the collection box 103.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
