Description

Technical Field

[0001] The invention belongs to the technical field of oil cleaning, in particular to an oil cleaning device used in grease production. Background Art

[0002] Oils occupy a pivotal position in the oil and fat production industry. They are the indispensable cornerstone of this industry. Specifically, the oil and fat industry widely defines those plant raw materials with an oil content of more than 10% as oils. These oils are not only of various types, including soybeans, peanuts, rapeseed, sesame, sunflower seeds, etc., but also each contains rich oil components, which is an important source for the production of edible oil, industrial oil and biofuel.

[0003] When the existing hydraulic oil press is working, as the hydraulic system continues to increase pressure, the oil cake is subjected to uniform and strong pressure in the pressing chamber. This pressure forces the oil inside the oil to be squeezed out and flows out through the tiny gaps on the outer wall of the oil press cylinder and the specially designed oil outlet channels. The oil then converges along these channels to the collecting ring on the outer wall of the oil press cylinder, and flows out through the oil outlet on the outer wall of the collecting ring and is collected in the container. This process ensures the effective extraction of the oil, and the design of the oil outlet allows the oil to be discharged smoothly from the oil press.

[0004] However, in the process of using the existing hydraulic oil press, because the oil is squeezed by squeezing rapeseed or other types of oil by a hydraulic rod, the hydraulic rod will first break the rapeseed during the squeezing process, and then squeeze out the oil in its cells, which will cause some of the broken rapeseed particles to adhere to the inner wall of the oil press cylinder. The long-term residual accumulation will cause the residual rapeseed particles to rot, and then they will be squeezed with the newly added rapeseed to squeeze oil. The bacteria produced by the corrupted rapeseed particles will be transferred to the squeezed oil, resulting in the problem of low oil quality. At the same time, some rapeseed particles will be blocked in the tiny gaps opened on the outer wall of the oil press cylinder, affecting the quality of the squeezed oil.

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0035] like Figures 1 to 8 As shown, an oil cleaning device used in oil production according to an embodiment of the present invention comprises a base 1, an oil pressing cylinder 2 is fixedly connected to the upper surface of the base 1, a hydraulic cylinder is arranged inside the oil pressing cylinder 2, two supporting columns 21 are fixedly connected to the upper surface of the base 1, a fixing plate 22 is fixedly connected to the top of the oil pressing cylinder 2, the fixing plate 22 is fixedly connected to the two supporting columns 21, a fixing ring 26 is fixedly connected to the top of each supporting column 21, a fixing block 23 is rotatably connected to the circumferential surface of one of the supporting columns 21, the fixing block 23 can seal the feed port of the oil pressing cylinder 2, a control console 214 is fixedly connected to the circumferential surface of the other supporting column 21, the control console 214 is used to control the oil press. The circumferential surface of the oil pressing cylinder 2 is rotatably connected with an oil outlet ring 215, and the oil outlet ring 215 is used for the outflow of grease. The circumferential surface of the oil pressing cylinder 2 is provided with an oil outlet slit 210. A positioning plate 27 is provided on one side of the fixed block 23. A first motor 32 is provided on the upper surface of the positioning plate 27. The output end of the first motor 32 is transmission-connected with a rotating shaft 311. The circumferential surface of the rotating shaft 311 is slidably connected with a fixed rod 312. Both ends of the fixed rod 312 are fixedly connected with a plurality of cleaning rods 318, and the plurality of cleaning rods 318 are all soft brushes. The plurality of cleaning rods 318 are used to clean the inner wall of the oil pressing cylinder 2.

[0036] Specifically, in the process of using the existing hydraulic oil press, because the oil is squeezed by squeezing rapeseed or other types of oil by a hydraulic rod, the hydraulic rod will first break the rapeseed during the squeezing process, and then squeeze out the oil in its cells, which will cause some of the broken rapeseed particles to adhere to the inner wall of the oil pressing cylinder 2. The residual accumulation for a long time will cause the residual rapeseed particles to rot, and then they will be squeezed and squeezed with the newly added rapeseed. The bacteria produced by the rotten rapeseed particles will be transferred to the squeezed oil, resulting in the problem of low oil quality;

[0037] Therefore, the present invention solves this problem by setting a certain structure. First, the pre-dried rapeseed or other oil materials are poured into the oil press cylinder 2. After being poured into the oil press cylinder 2, a pressure pad is placed above the oil materials. The pressure pad limits the top of the rapeseed and can assist the hydraulic cylinder to squeeze the oil materials. After the oil materials are placed, the fixed block 23 arranged on the upper surface of the rotating fixed plate 22 is rotated. The fixed block 23 can seal the feed port of the oil press cylinder 2. After the sealing is completed, the hydraulic cylinder at the bottom of the oil press cylinder 2 is started. The hydraulic cylinder will drive the squeezing rod at its output end to squeeze the rapeseed. The squeezing rod cooperates with the wall of the oil press cylinder 2 and the pressure pad to rupture the rapeseed, and the oil in the rapeseed is squeezed out, and then flows out along a plurality of oil outlet slits 210 opened on the circumferential surface of the oil press cylinder 2. The oil flowing out of the oil outlet slits 210 will flow to the outlet The oil flows into the oil ring 215 through a port of the oil ring 215. After the oil pressing is completed, the fixed block 23 is rotated to remove the oil plate after the oil pressing is completed. After the oil pressing is completed, the fixed block 23 is rotated again to transfer the positioning plate 27 to the top of the oil pressing cylinder 2. Then, the first motor 32 on the positioning plate 27 is moved downward to drive the rotating shaft 311 at its output end to be inserted into the oil pressing cylinder 2. Then, the first motor 32 is started. The first motor 32 drives the rotating shaft 311 to rotate, which will drive the fixed rod 312 connected to the circumferential surface of the rotating shaft 311 to rotate. In this way, the cleaning rods 318 at both ends of the fixed rod 312 can clean the rapeseed residue on the inner wall of the oil pressing cylinder 2. After the residue is cleaned out, the effect of improving the oil pressing quality is achieved, and the squeezed oil is prevented from being contaminated by the residual residue, thereby achieving the effect of improving the oil quality.

[0038] The problem is solved that because oil pressing is performed by squeezing rapeseed or other types of oil materials through a hydraulic rod, the hydraulic rod will first break the rapeseed during the squeezing process, and then squeeze out the oil in the cells, which will cause some of the broken rapeseed particles to adhere to the inner wall of the oil pressing cylinder 2. The residual accumulation over a long period of time will cause the residual rapeseed particles to become corrupt, and then they will be squeezed and pressed with the newly added rapeseed, and the bacteria produced by the corrupt rapeseed particles will be transferred to the squeezed oil, resulting in the problem of low oil quality.

[0039] like Figure 3As shown, the upper surface of the positioning plate 27 of this embodiment is fixedly connected with a connecting plate 29, a first guide rail 3 is opened on one side of the connecting plate 29, a first guide plate 31 is slidably connected in the first guide rail 3, a first motor 32 is fixedly connected to the first guide plate 31, a first gear 33 is fixedly connected to the output end of the first motor 32, the first gear 33 is transmission-connected with a first steel strip 34, an end of the first steel strip 34 away from the first gear 33 is transmission-connected with a second gear 35, a fixed tube 36 is fixedly connected to the middle of the second gear 35, and a rotating shaft 311 is fixedly connected to the lower surface of the fixed tube 36.

[0040] Specifically, first, by starting the first guide rail 3, the first electrified guide rail will drive the first guide plate 31 slidably connected to its temporal portion to move downward, thereby driving the first motor 32 and the fixed rod 312 slidably arranged on the rotating shaft 311 to be inserted into the oil pressing cylinder 2. In addition, after the fixed rod 312 is inserted into the oil pressing cylinder 2, the first motor 32 is started. The first motor 32 serves as a power source, and its output end drives the first gear 33 to rotate, thereby driving the first strip steel 34 meshing therewith to perform a circular motion. This motion is seamlessly connected to the second gear 35 through the transmission of the first strip steel 34, thereby realizing long-distance transmission and conversion of power. The second gear 35 drives the fixed tube 36 fixed at its center and the rotating shaft 311 connected thereto, and drives the cleaning rod 318 at the end of the fixed rod 312 through the rotating shaft 311 to clean the inner wall of the oil pressing cylinder 2, thereby achieving the effect of improving the overall working efficiency and realizing efficient transmission of power.

[0041] like Figure 4 As shown, in this embodiment, a fixing hole 37 is opened inside the fixed tube 36, a storage box 38 is fixedly connected to the upper surface of the fixed tube 36, and a cleaning agent is stored in the storage box 38. A pressure pump 39 is fixedly connected to the upper surface of the storage box 38, and a bottom end of the rotating shaft 311 is fixedly connected to a bottom plate 313, and a plurality of spray holes 314 are opened on the circumferential surface of the bottom plate 313.

[0042] Specifically, after the detergent in the storage box 38 is pressurized by the pressure pump 39, it is transported to the spray hole 314 of the chassis 313 through the fixed hole 37 in the fixed tube 36. As the rotating shaft 311 rotates, the chassis 313 drives the spray hole 314 to rotate around the axis, thereby achieving uniform spraying of the detergent, improving the cleaning efficiency of the fixed rod 312, and ensuring the comprehensiveness of the cleaning coverage. It can effectively utilize the rotational power for automatic cleaning operations, thereby improving work efficiency and cleaning quality.

[0043] like Figure 3 As shown, in this embodiment, a sealing cover 310 is threadedly connected to the upper surface of the storage box 38. The sealing cover 310 is used to replenish the cleaning agent. The circumferential surface of the sealing cover 310 is provided with a plurality of anti-slip grooves.

[0044] Specifically, the sealing cover 310 is fixedly connected to the storage box 38 through a threaded connection to ensure that the detergent will not leak during storage. The anti-slip design can achieve stable rotation of the sealing cover 310 to replenish the detergent, thereby improving the convenience and safety of operation. Embodiment 2

[0045] like Figures 1 to 8 As shown, compared with Example 1, another implementation of the present invention is: two limit bars 327 are fixedly connected to the circumferential surface of the rotating shaft 311, and the two limit bars 327 are both powered guide rails. A connecting hole 315 is provided on the surface of the fixed rod 312 corresponding to the position of the limit bars 327, and a first cavity 316 is provided at both ends of the fixed rod 312. A cleaning column 321 is rotatably arranged in each first cavity 316, and the cleaning column 321 is used to clean the oil outlet gap 210.

[0046] Specifically, at the same time, the tiny gaps formed on the outer wall of the oil pressing cylinder 2 will be clogged with some rapeseed particles, thus affecting the quality of the extracted oil;

[0047] Therefore, by using the two limit bars 327 fixed on the rotating shaft 311 as electrified guide rails, the connecting hole 315 on the fixed rod 312 cooperates with the limit bar 327, ensuring that the fixed rod 312 can move stably along the rotating shaft 311. At the same time, the electrically controlled cleaning column 321 rotates in the first cavity 316. The cleaning column 321 can be driven by the rotating shaft 311 to get into the oil outlet gap 210 and clean the inside of the oil outlet gap 210 in detail, thereby improving the cleaning efficiency and ensuring the thoroughness of the cleaning, solving the problem of easy blockage of the oil outlet gap 210 and improving work efficiency. At the same time, it solves the problem of reduced oil outlet rate due to blockage of the oil outlet gap 210.

[0048] like Figure 6 As shown, in this embodiment, the first cavity 316 is rotatably connected to a rotating rod 319, an auxiliary rod 320 is fixedly connected to the circumferential surface of the rotating rod 319, one end of the auxiliary rod 320 is rotatably connected to a cleaning column 321, and a plurality of hard brushes are fixedly connected to the circumferential surface of the cleaning column 321.

[0049] Specifically, in the first cavity 316, the rotating rod 319 is linked with the auxiliary rod 320 and the cleaning column 321, so that the cleaning column 321 can be stuck in the oil outlet gap 210 under the drive of the rotating rod 319, and then the fixed rod 312 is controlled to move up and down through the limit bar 327, so that the oil outlet gap 210 is deeply cleaned by a hard brush, and the stubborn dirt in the oil outlet gap 210 is effectively removed, thereby improving the cleaning efficiency and effect, ensuring that the oil outlet gap 210 is unobstructed, and improving the quality of oil output.

[0050] like Figure 7As shown, in this embodiment, a second cavity 322 is opened on one side of the inner wall of the first cavity 316, and a plurality of compression springs 323 are fixedly connected to the inner wall of the second cavity 322. One end of the plurality of compression springs 323 is fixedly connected to the same protective plate 324, and the protective plate 324 is used to protect the cleaning column 321. The inner wall of the second cavity 322 is an electrophoretic magnet, and the protective plate 324 is made of magnetic material.

[0051] Specifically, the compression spring 323 in the second cavity 322 is connected to the protective plate 324, which provides protection for the cleaning column 321 to prevent it from being damaged by accidental impact when not in operation. At the same time, the electrophoretic magnetic block is combined with the protective plate 324 made of magnetic material to realize automatic closing and opening functions. When the cleaning column 321 is working, the electrophoretic magnetic block is charged, thereby adsorbing the protective plate 324, and the protective plate 324 automatically retreats; when not in operation, the electrophoretic magnetic block is energized and de-energized, and the magnetism is restored. The protective plate 324 covers the cleaning column 321 under the action of the compression spring 323 to form a protective barrier, thereby ensuring the safety and cleaning effect of the cleaning column 321.

[0052] like Figure 8 As shown, in this embodiment, two micro air pumps 325 are fixedly connected to the lower surface of the fixed rod 312, and a connecting pipe 326 is fixedly connected to one side of the micro air pump 325. Each end of the fixed rod 312 is provided with a plurality of air outlet holes 317, and the air outlet holes 317 are used to blow out rapeseed particles.

[0053] Specifically, the air flow is delivered to the air outlet 317 on the lower surface of the fixed rod 312 by utilizing the micro air pump 325 and the connecting pipe 326 to blow out the rapeseed particles cleaned by the cleaning column 321, thereby preventing the rapeseed particles from entering the oil pressing cylinder 2, and effectively removing the rapeseed particles attached to the oil outlet slit 210 or the surrounding area, thereby further improving the cleaning effect and ensuring the comprehensiveness and efficiency of the cleaning.

[0054] like Figure 2 As shown, a connecting groove 216 is provided on one side of the fixed block 23 of the present embodiment, and the connecting groove 216 can be snap-connected with one of the support columns 21. A fixing groove 24 is provided on one side of the connecting groove 216, and an insert rod 25 is inserted into the fixing groove 24. The insert rod 25 is used to fix the fixed block 23. A first groove body 28 is provided on the upper surface of the fixed block 23, and the first groove body 28 is used to protect the fixing rod 312.

[0055] Specifically, the fixing block 23 is clamped with the support column 21 through the connecting groove 216 to achieve a stable connection; at the same time, the insertion rod 25 is inserted into the fixing groove 24 to enhance the stability of the connection. In addition, the first groove body 28 on the fixing block 23 provides additional protection space for the fixing rod 312, preventing external impact from directly affecting the fixing rod 312, improving the reliability of the connection, and enhancing the stability and durability of the overall structure.

[0056] like Figure 2 As shown, in this embodiment, a connecting block 211 is fixedly connected to the circumferential surface of one of the support columns 21, a connecting column 212 is fixedly connected to the upper surface of the connecting block 211, and an auxiliary plate 213 is rotatably connected to the circumferential surface of the connecting column 212. The auxiliary plate 213 is used to place a container for collecting grease.

[0057] Specifically, the firm connection between the connecting block 211 and the connecting column 212 enables the auxiliary plate 213 to rotate around the connecting column 212, thereby conveniently adjusting the angle to place a container for collecting grease, thereby improving the practicality of the equipment, making grease collection more convenient and efficient, and adapting to the needs of different work scenarios through a flexible rotation mechanism.

[0058] Working principle: first, pour the pre-dried rapeseed or other oil materials into the oil press cylinder 2. After pouring into the oil press cylinder 2, place a pressure pad above the oil materials. The pressure pad limits the top of the rapeseed and can assist the hydraulic cylinder to squeeze the oil materials. After the oil materials are placed, rotate the fixed block 23 arranged on the upper surface of the fixed plate 22, and the fixed block 23 can seal the feed port of the oil press cylinder 2. After the sealing is completed, start the hydraulic cylinder at the bottom of the oil press cylinder 2, and the hydraulic cylinder will drive the squeezing rod at its output end to squeeze the rapeseed. The squeezing rod is matched with the wall of the oil press cylinder 2 and the pressure pad. The rapeseed is broken by the combination, and the oil in the rapeseed is squeezed out, and then flows out along the plurality of oil outlet slits 210 opened on the circumferential surface of the oil pressing cylinder 2, and the oil flowing out of the oil outlet slits 210 flows into the oil outlet ring 215, and then flows into the collection container through a port of the oil outlet ring 215. After the oil pressing is completed, the fixed block 23 is rotated to remove the oil material tray after the oil pressing is completed, and the fixed block 23 is rotated again after taking it out, and the positioning plate 27 is transferred to the top of the oil pressing cylinder 2, and then the first motor 32 on the positioning plate 27 is moved downward to drive the rotating shaft 311 at its output end to be inserted into the oil pressing cylinder 2;

[0059] Then, by starting the first guide rail 3, the first electrified guide rail will drive the first guide plate 31 slidably connected to its temporal portion to move downward, thereby driving the first motor 32 and the fixing rod 312 slidably arranged on the rotating shaft 311 to be inserted into the oil pressing cylinder 2. In addition, after the fixing rod 312 is inserted into the oil pressing cylinder 2, the first motor 32 is started. The first motor 32 serves as a power source, and its output end drives the first gear 33 to rotate, thereby driving the first strip steel 34 meshing therewith to perform a circular motion. This motion is seamlessly connected to the first strip steel 34 through the transmission of the first strip steel 34. The second gear 35 realizes the long-distance transmission and conversion of power. The second gear 35 drives the fixed tube 36 fixed at the center thereof and the rotating shaft 311 connected thereto. The rotating shaft 311 drives the cleaning rods 318 at the ends of the fixed rods 312 to clean the inner wall of the oil pressing cylinder 2. In this way, the cleaning rods 318 at both ends of the fixed rods 312 can clean the rapeseed residues on the inner wall of the oil pressing cylinder 2. After the residues are cleaned out, the effect of improving the quality of oil pressing is achieved, and the extracted oil is prevented from being contaminated by the remaining residues, thereby achieving the effect of improving the quality of the oil.

[0060] The two limit bars 327 fixed on the rotating shaft 311 are used as the electrified guide rails, so that the connection hole 315 on the fixed rod 312 cooperates with the limit bars 327, ensuring that the fixed rod 312 can stably move along the rotating shaft 311. At the same time, the electrically controlled cleaning column 321 rotates in the first cavity 316. The cleaning column 321 can be driven by the rotating shaft 311 to get into the oil outlet gap 210, and clean the inside of the oil outlet gap 210 in detail, thereby improving the cleaning efficiency and ensuring the thoroughness of the cleaning, solving the problem that the oil outlet gap 210 is easily blocked, and improving the working efficiency; at the same time, solving the problem that the oil outlet gap 210 is blocked and causing the oil outlet rate to decrease;

[0061] At the same time, the micro air pump 325 and the connecting pipe 326 are used to deliver the air flow to the air outlet 317 on the lower surface of the fixed rod 312 to blow out the rapeseed particles cleaned by the cleaning column 321, thereby preventing the rapeseed particles from entering the oil pressing cylinder 2, effectively removing the rapeseed particles attached to the oil outlet slit 210 or the surrounding area, further improving the cleaning effect, and ensuring the comprehensiveness and efficiency of the cleaning;

[0062] In addition, when the fixed rod 312 slides along the limit bar 327 toward the inside of the oil pressing cylinder 2, the detergent in the storage box 38 is pressurized by the pressure pump 39 and then transported to the spray hole 314 of the chassis 313 through the fixed hole 37 in the fixed pipe 36. As the rotating shaft 311 rotates, the chassis 313 drives the spray hole 314 to rotate around the axis to achieve uniform spraying of the detergent, thereby improving the cleaning efficiency of the fixed rod 312 and ensuring the comprehensiveness of the cleaning coverage. The rotary power can be effectively used for automatic cleaning operations, thereby improving work efficiency and cleaning quality. Finally, the residual detergent and cleaned rapeseed particles in the oil pressing cylinder 2 are flushed out by water to complete the cleaning of the oil pressing cylinder 2.
