Description

Technical Field

[0001] This invention relates to the field of lubricating oil processing technology, and in particular to an automatic feeding device for lubricating oil processing. Background Technology

[0002] Lubricating oil is an important petrochemical product with a wide variety of types, widely used in production and daily life. Finished lubricating oil mainly consists of base oil and additives, with base oil making up the majority. Therefore, the performance and quality of the base oil have a crucial impact on the quality of the lubricating oil. Additives can improve the performance of the base oil and are an important component of lubricating oil. Lubricating oil is a liquid lubricant used in various types of machinery to reduce friction and protect the machinery and processed parts. Its main functions include controlling friction and reducing wear, cooling, and sealing.

[0003] However, existing technologies require the continuous addition of additives during lubricant processing. For example, Chinese patent application CN112108053A discloses an automatic feeding device for lubricant processing, comprising a mixing tank, a main shaft rotatably connected inside the mixing tank, a mixing disc movably fitted around the outer ring of the main shaft, mixing blades rotatably connected inside the mixing disc, a first linkage block movably connected to the side wall of the mixing tank, a linkage rod fixedly connected to the outer side of the first linkage block, a raw material inlet fixedly connected to the top of the mixing tank, a rotating disc movably connected to the cross-sectional end of the raw material inlet, a second linkage block fixedly connected to the outer ring of the rotating disc, an arc groove formed on the surface of the rotating disc, a fixed disc movably connected to the ground of the rotating disc, a fixed shaft fixedly connected to the surface of the fixed disc, and a baffle fixedly connected to the upper end of the fixed shaft. This automatic feeding device for lubricant processing achieves the effect of uniformly mixing lubricant through the coordinated use of the mixing tank, main shaft, mixing disc, and mixing blades.

[0004] While the above-mentioned solutions have the advantages mentioned above, they also have disadvantages: when additives are continuously added to the stirred lubricating oil, the traditional method of adding additives is to pour them directly into the oil. This method cannot guarantee an internal seal and is prone to generating impurities during the addition process. At the same time, directly poured additives cannot be effectively filtered, and filtration is often required before the additives are injected, which is a rather cumbersome operation. Therefore, there is an urgent need for a more sealed automatic feeding device for lubricating oil processing that can solve these problems without the need for pre-filtration of additives. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of the existing technology of directly pouring additives, which cannot guarantee internal sealing, are prone to generating impurities during the addition process, and cannot be effectively filtered, often requiring filtration before the additive is injected, which is a rather cumbersome operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic feeding device for lubricating oil processing, comprising: a processing cylinder, a storage bin, and a feeding cylinder; multiple support legs are evenly arranged on the outer surface of the processing cylinder; a rotating shaft is rotatably embedded inside the processing cylinder; multiple agitator blades are fixedly sleeved on the outer surface of the rotating shaft; a water level monitor is installed inside the processing cylinder; a motor is fixedly installed on the side of the storage bin near the processing cylinder; the output shaft of the motor is fixedly connected to the rotating shaft; a first bevel gear is fixedly sleeved on the outer surface of the motor's output shaft; multiple fixing rods are fixedly connected to one side of the outer surface of the storage bin; one end of the outer surface of each fixing rod... A second bevel gear is fixedly connected and meshes with a first bevel gear. An inner shaft is rotatably embedded inside the storage hopper. A third bevel gear is fixedly sleeved on one end of the outer surface of the inner shaft and meshes with the second bevel gear. A filter plate is provided inside the storage hopper. A pressing plate is slidably embedded inside the storage hopper. Feeding ports are opened on both sides of the outer surface of the storage hopper. A limiting groove is opened inside the storage hopper. An inner groove is opened inside the limiting groove. A turntable is fixedly connected to one end of the outer surface of the inner shaft. A rotating arm is rotatably connected to the outer surface of the turntable. A connecting rod is rotatably connected to one end of the outer surface of the rotating arm.

[0007] In a preferred embodiment, L-shaped sealing strips are fixedly connected to both sides of the outer surface of the pressing plate, the connecting rod is rotatably installed on one side of the outer surface of the L-shaped sealing strip, the L-shaped sealing strip is slidably embedded in the inner groove, and multiple wedges are provided on one side of the outer surface of the filter plate.

[0008] The technical effect of adopting the above-mentioned further solution is that the L-shaped sealing strip is used to ensure the side sealing when the pressing plate moves up and down, so as to avoid leakage of the injected additive.

[0009] In one preferred embodiment, a second motor is fixedly installed on one side of the outer surface of the feed cylinder, and the output shaft of the second motor is fixedly connected to a threaded rod, with a threaded sleeve fitted on the outer surface of the threaded rod.

[0010] The technical effect of adopting the above-mentioned further solution is that the cooperation between the threaded rod and the screw ring, under the limitation of the multi-section rod, will drive the sealing plug to push and pull back and forth, thereby extracting the additives filtered inside the storage bin.

[0011] In a preferred embodiment, a sealing plug is fixedly fitted on the outer surface of the screw cylinder, and a plurality of multi-section rods are fixedly connected to one side of the outer surface of the sealing plug. The multi-section rods are fixedly installed inside the feed cylinder, and a plurality of one-way valve ports are provided on one side of the outer surface of the feed cylinder.

[0012] The technical effect of adopting the above-mentioned further solution is that the one-way valve interface is used to connect to the feed port, and at the same time, the one-way valve interface acts as a one-way valve to prevent the additive drawn into the feed cylinder from returning to the storage bin from the feed port when it is pushed out.

[0013] In one preferred embodiment, one of the one-way valve interfaces is provided with a feed port, and the other one-way valve interfaces are provided with a feed port, the other end of which is connected to the top of the outer surface of the processing cylinder.

[0014] The technical effect of adopting the above-mentioned further solution is that the setting of multiple extrusion ports corresponds to the isolation plate on the bottom inner plate, which reduces the spraying space and increases the spraying rate.

[0015] In a preferred embodiment, the other end of the outer surface of the feed inlet is connected to the storage bin, and slots are provided on both sides of the outer surface of the pressing plate, with a push-pull rod slidably embedded inside the slots.

[0016] The technical effect of adopting the above-mentioned further solution is that the push-pull rod is used to pull and adjust the mode switching of the multi-section plate from the side. The push-pull rod can be hidden on the side of the pressing plate to avoid getting stuck on the inner wall of the storage bin when it moves down.

[0017] In one preferred embodiment, the pressing plate has multiple sections fixedly installed inside, the multiple sections are fixedly connected to the push-pull rod, and side grooves are provided on both sides of the inner wall of the pressing plate.

[0018] In one preferred embodiment, a movable strip is slidably embedded on one side of the inner wall of the side groove, and multiple rotating strips are rotatably embedded inside the movable strip, with scraper blades fixedly sleeved on the outer surface of the multiple rotating strips.

[0019] The technical effect of adopting the above-mentioned further solution is that the scraper blade is set so that when the pressing plate is pressed down, the scraper blade abuts against the wedge strip and rotates at a small angle. As it moves up and down continuously, it rotates continuously, thereby transferring the small additive particles accumulated on the surface of the filter plate to one side of the upper surface of the filter plate.

[0020] In one preferred embodiment, a plurality of springs are fixedly connected to the side of the movable strip near the inner wall of the pressing plate, and the springs are fixedly installed on one side of the inner wall of the pressing plate.

[0021] The technical effect of adopting the above-mentioned further solution is that the spring is used to push a row of scraper blades out of the interior of the pressing plate during mode switching, ensuring contact with the filter plate surface.

[0022] In one preferred embodiment, the processing cylinder is provided with an inner perforated plate, an isolation plate is fixedly installed on the top of the outer surface of the inner perforated plate, and multiple injection holes are opened on the outer surface of the inner perforated plate.

[0023] The technical effect of adopting the above-mentioned further solution is that the isolation plate is used to increase internal pressure in conjunction with the extrusion port.

[0024] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0025] 1. In this invention, the processing cylinder, storage hopper, and feed cylinder are fixed by external fixing devices, such as welding or bolts. The relative positions of the fixed processing cylinder, storage hopper, and feed cylinder are such that the support legs at the bottom of the processing cylinder are evenly distributed on its exterior, providing stable support. The storage hopper serves as the additive addition point, connected to the feed inlet via an external pipe. The additive is injected into the storage hopper. The feed inlet is non-circular, designed to correspond to the thickness of the pressing plate, ensuring that no additive appears on the upper part of the pressing plate when it moves downwards. When the pressing plate moves downwards and contacts the filter plate, it blocks the feed inlet. The stirring blades on the rotating shaft are driven by the output shaft of the motor. The motor rotates, with the output shaft fixedly connected to the rotating shaft, used for stirring the mixture inside the processing cylinder. Simultaneously, a first bevel gear is fitted onto the motor's output shaft, working in conjunction with a second bevel gear fixed to the side of the storage hopper and a third bevel gear fitted onto the inner shaft, driving the rotation of the inner shaft. The inner shaft rotates and is embedded inside the storage hopper, extending to the other side. One end of the inner shaft on the other side is connected to a turntable. A rotating arm mounted on the turntable, along with a connecting rod, pulls the L-shaped sealing strip up and down, sliding it back and forth within the inner groove. The pressing plate moves up and down synchronously. On the side of the third bevel gear, a turntable, rotating arm, and connecting rod are similarly installed as needed to accommodate storage hoppers with longer widths. To prevent one side from pulling down and the other side from getting stuck, as the pressing plate moves down, it squeezes the additive on the upper part of the filter plate. The additive passes through the filter holes on the filter plate and enters the bottom of the storage bin. At the same time, the second motor starts, and the output shaft of the second motor drives the threaded rod to rotate. The screw ring is threaded onto the threaded rod and is externally connected to a sealing plug. The sealing plug is limited by multiple multi-section rods, which then drive the sealing plug to push and pull back and forth. Multiple one-way valve interfaces are one-way valves. The one-way valve connected to the feed port is used to draw the additive into the feed cylinder as much as possible, while the other one-way valves are used to push out the additive drawn into the feed cylinder. The one-way valve interfaces used for pushing out are set to multiple This device allows for selective external extrusion ports for additive isolation and addition, accommodating different injection rate requirements. Correspondingly, an internal perforated plate and isolation plate are installed inside the processing cylinder to divide the sprayed layer after injection into two parts, improving the spraying effect. The number of divided parts can be set as needed to increase the spraying capacity, thereby improving the mixing effect of the additive. This solves the problem of the direct pouring method in the existing technology, which cannot guarantee internal sealing, is prone to generating impurities during the addition process, and cannot effectively filter additives directly poured in, often requiring filtration before additive injection, which is cumbersome.

[0026] 2. This invention addresses the issue of larger particles remaining on the upper surface of a filter plate after filtration. It involves switching the contact surface between the pressing plate and the filter plate, pulling the push-pull rod to retract the multi-section plate, exposing the scraper blades. Under the action of a spring, a movable strip is pushed out, causing multiple scraper blades to press against the filter plate surface. The filter plate's stroke involves reciprocating downward and upward movement. As the rotating strip moves downward, it presses against the wedge strip on the filter plate, finely adjusting the angle of the scraper blades. The slightly rotating scraper blades push the residual particles on the filter plate to one side. This continuous downward and upward movement continuously pushes the residue on the filter plate surface to one side, eventually moving all the residue to one side. A sliding sealing door can be opened on the side of the pressing plate closest to the residue. Simply opening the sliding sealing door and removing the accumulated residue pushed to one side achieves surface cleaning of the filter plate. Attached Figure Description

[0050] Working principle:

[0051] Processing cylinder 1, storage bin 2, and feed cylinder 3 are fixed by external fixing devices, such as welding or bolts. The relative positions of the fixed processing cylinder 1, storage bin 2, and feed cylinder 3 are as follows: Figures 1-3As shown, the support legs 101 at the bottom of the processing cylinder 1 are evenly distributed on the outside of the processing cylinder 1, providing stable support for the processing cylinder 1. The storage bin 2 serves as the additive addition location and is connected to the feed port 201 via an external pipe, allowing the additive to be injected into the storage bin 2. The feed port 201 is non-circular and is designed to correspond to the thickness of the pressing plate 6, ensuring that no additive appears on the upper part of the pressing plate 6 when it moves down. When the pressing plate 6 moves down and fits against the filter plate 5, it blocks the feed port 201. The stirring blade 103 on the rotating shaft 102 is driven to rotate by the output shaft of the motor 4. The output shaft is fixedly connected to the rotating shaft 102 and is used to stir the inside of the processing cylinder 1. The mixture, and the output shaft of motor 4 is fitted with a first bevel gear 401, which works in conjunction with a second bevel gear 402 fixed to the side of storage silo 2 and a third bevel gear 403 fitted on the inner shaft 404, driving the inner shaft 404 to rotate. The inner shaft 404 rotates and is embedded inside the storage silo 2, and also extends to the other side of the storage silo 2. One end of the inner shaft 404 on the other side is connected to a turntable 441. Through the rotating arm 442 installed on the turntable 441, under the rotation of the turntable 441, the connecting rod 443 pulls the L-shaped sealing strip 601 up and down to slide in the inner groove 221, and the pressing plate 6 moves up and down synchronously. On the side, a turntable 441, a rotating arm 442, and a connecting rod 443 are also provided as needed to accommodate the longer width of the storage bin 2, preventing one side from being pulled down and the other side from getting stuck. As the pressing plate 6 moves down, it squeezes the additive injected into the upper part of the filter plate 5. The additive passes through the filter holes on the filter plate 5 and enters the bottom of the storage bin 2. At the same time, the second motor 301 starts, and the output shaft of the second motor 301 drives the threaded rod 302 to rotate. The screw ring 305 is threaded onto the threaded rod 302 and is externally connected to a sealing plug 304. The sealing plug 304 is limited by multiple multi-section rods 303, which in turn drives the sealing plug 304 to push and pull back and forth. Multiple one-way valves Interface 306 is a one-way valve. The one-way valve connected to the feed port 307 is used to draw the additive into the feed cylinder 3 as much as possible, while the other one-way valves are used to push out the additive drawn into the feed cylinder 3. Multiple one-way valve interfaces 306 are provided here for pushing out, and the external extrusion port 308 can be selectively connected as needed for the addition of additives in isolation, which is suitable for different injection rate requirements. Correspondingly, an inner hole plate 7 and an isolation plate 701 are set inside the processing cylinder 1 to divide the spray layer after injection into two parts, thereby improving the spraying effect. The number of divided parts can be set as needed to improve the spraying capacity, thereby improving the mixing effect of the additive.

[0052] For larger particles remaining on the upper surface of filter plate 5 after filtration, switch the contact surface between the pressing plate 6 and filter plate 5, pull the push rod 622 to retract the multi-section plate 621, exposing the scraper blades 606. Under the action of the spring 641, the movable strip 604 is pushed out, and then multiple scraper blades 606 are pressed against the surface of filter plate 5. The stroke of filter plate 5 is a reciprocating downward and upward movement. When the rotating strip 605 moves down, the wedge strip 501 pressed against the filter plate 5 will make a fine adjustment to the angle of the scraper blades 606. The slightly rotating scraper blades 606 will push the residual particles on filter plate 5 to one side. The continuous reciprocating downward and upward movement continuously pushes the residue on the surface of filter plate 5 to one side, and then moves all the residue on the surface of filter plate 5 to one side. A push-pull sealing door can be opened on the side of the pressing plate 6 near the residue. Simply open the push-pull sealing door and take out the accumulated material pushed to one side to achieve surface cleaning of filter plate 5.

[0053] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
