The unsaturated fatty acids such as linoleic acid and nutrients such as vitamin E it contains can be well absorbed by the body. It has a certain effect of softening blood vessels and delaying aging.

[0003] During the production process of rapeseed oil, it is processed by pressing and other methods, so that the oil is pressed out of the residue and separated from the residue. The patent publication number is CN220685039U, which is a rapeseed oil residue separation device. Its structure mainly includes a support frame and a vertical frame installed on the upper end of the support frame. The support frame is provided with an oil barrel, and a detachable filter barrel is provided inside the oil barrel.

[0050] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0051] Embodiment 1

[0052] Please refer to the accompanying drawings, the present invention provides a technical solution:

An oil discharge pipe 101 is provided on one side of the bottom of the oil pressing box 100, and a valve is provided in the oil discharge pipe 101;

[0054] Two vertical partitions 300 are symmetrically fixed on the upper part of the oil pressing box 100, and a transverse partition 301 is fixed between the middle parts of the two vertical partitions 300. The position between the side wall of the oil pressing box 100 and the vertical partition 300 is set as a pressing groove, and the position between the two vertical partitions 300 and above the transverse partition 301 is set as a material storage groove;

[0055] like Figure 3 As shown, feed slots 305 are provided on the vertical partition 300 at the two ends corresponding to the transverse partition 301, a sealing assembly is provided at the bottom of the transverse partition 301 at the positions corresponding to the two feed slots 305, an oil filter assembly is slidably connected to the bottom of the pressing tank, a moving assembly is provided at the bottom of the transverse partition 301, and the moving assembly is correspondingly connected to the two oil filter assemblies;

[0056] A horizontal fixed plate 102 is provided in the middle of the oil pressing box 100, and the oil filter assembly is slidably connected to the top surface of the fixed plate 102. A V-shaped slag trough 500 is provided below the fixed plate 102, and the top two ends of the slag trough 500 are respectively fixedly connected to the two side walls of the oil pressing box 100. A scraper assembly is provided in the slag trough 500, and a discharge port is provided on the side wall of the oil pressing box 100 corresponding to the end position of the slag trough 500, and a sealing plate is provided at the discharge port, and drainage notches are provided on the two side walls of the slag trough 500 corresponding to the position of the oil filter assembly, and a switching structure is provided at the drainage notch.

[0057] When rapeseed oil is produced by pressing, the rapeseed material to be pressed is stored in a storage tank. The sealing component is first started to open the feed slot 305 on one side, and material is added to the pressing tank on the corresponding side. The feed slot 305 is then closed, and the pressing component moves to press the pressed tank after loading. At the same time, the sealing component opens the feed slot 305 on the other side, and the storage tank loads material into another pressed tank, so that the pressing process and loading in the oil pressing box 100 can be carried out simultaneously, thereby improving the pressing efficiency.

[0058] When the pressing tank is being pressed, the switching structure opens the drainage slot, allowing the squeezed oil to pass through the drainage slot on the slag tank 500 and fall to the bottom of the oil pressing box 100 for collection; after the pressing is completed, the switching structure moves to close the drainage slot on the side wall of the slag tank 500, and then moves the oil filter assembly on this side through the moving assembly to open the bottom of the pressing tank, and at the same time, the bottom end of the vertical partition 300 moves relative to the top of the oil filter assembly, and the slag on the top is cleaned, so that the slag falls into the slag tank 500 for collection, thereby realizing the separation and collection of oil and slag.

[0059] When a certain amount of oil and slag is collected, the oil drain pipe 101 is opened to discharge and transfer the oil for subsequent finishing treatment, etc. The slag in the slag trough 500 is scraped and moved by the scraping assembly to the discharge port of the oil pressing box 100, and the discharge port is opened to take out the slag for subsequent treatment.

[0060] Among them, Figure 3 As shown, the oil filter assembly includes an oil filter plate 400 located at the bottom of the pressing tank, a plurality of oil filter holes 401 are evenly arranged on the oil filter plate 400, and the oil filter plate 400 is slidably connected between the bottom end of the vertical partition plate 300 and the top surface of the fixed plate 102, and a movable seat 402 is fixed to one end of the oil filter plate 400 close to the fixed plate 102, and a movable groove 403 is arranged on the top of the movable seat 402, and as shown in FIG. Fig.11As shown, the side of the movable seat 402 away from the vertical partition 300 is connected to the inner wall of the oil pressing box 100 through a spring, and a movable component is provided in the middle of the bottom of the transverse partition 301, and the movable component is correspondingly connected to the movable groove 403.

[0061] When one of the pressing grooves is unloading the slag material, the moving seat 402 and the oil filter plate 400 on the corresponding side are driven to move through the cooperation of the moving assembly and the moving groove 403, so that the bottom of the pressing groove is opened, and during the movement of the oil filter plate 400, the top of the oil filter plate 400 is scraped through the bottom end of the vertical partition 300, so that when the end of the oil filter plate 400 moves to the bottom end of the vertical partition 300, the material on the oil filter plate 400 can fall from the oil filter plate 400 and then be collected by the slag groove 500. After the slag material finishes falling, the moving assembly is disconnected from the moving groove 403, and the moving seat 402 and the oil filter plate 400 return to their original positions under the action of the spring, closing the bottom of the pressing groove for continuing the loading and pressing process.

[0062] Among them, Figure 5 As shown, the moving assembly includes a telescopic block 601 slidably connected to the middle of the bottom of the diaphragm 301, and one side of the telescopic block 601 is connected to the bottom of the diaphragm 301 through a second hydraulic telescopic rod 600, as shown in FIG. Figure 7 As shown, racks 602 are symmetrically fixed at both ends of the telescopic block 601, and a transmission gear 603 is meshed on the outer side of the rack 602. The two transmission gears 603 are connected to the bottom of the diaphragm 301, and a rotating frame 604 is fixed to one side of the bottom of each transmission gear 603. The two rotating frames 604 are symmetrically arranged;

[0063] like Figure 7 As shown, a spring slot 605 is provided in the outer section of the rotating frame 604, and a spring seat 700 is connected to the spring slot 605 via a spring. Figure 8 As shown, a horizontal limiting sliding shaft 702 is fixed in the middle of the inner side end of the spring seat 700, a limiting sliding hole 606 is provided in the middle of the inner side end of the spring groove 605, and the limiting sliding shaft 702 is slidably connected to the limiting sliding hole 606, and a vertical driving shaft 701 is rotatably connected to the bottom of the spring seat 700, and the driving shaft 701 is correspondingly connected to the moving groove 403, and two shaft entry grooves 404 are symmetrically provided in the middle of the side wall of the moving groove 403, and a shaft exit groove 405 is provided at the outer position of the side wall of the moving groove 403 corresponding to the shaft entry groove 404, as shown in FIG. Fig.12 described.

[0064] When the moving seat 402 and the oil filter plate 400 on one side need to be moved, the second hydraulic telescopic rod 600 drives the telescopic block 601 and the rack 602 to move, so that the transmission gears 603 on both sides simultaneously drive the rotating frame 604 to rotate toward the moving seat 402, and during the rotation process, the driving shaft 701 on the spring seat 700 gradually approaches the side wall of the moving seat 402, and after contacting, it is squeezed by the moving seat 402, so that the spring seat 700 and the driving shaft 701 slide relative to the spring groove 605;

[0065] When the driving shafts 701 on the two rotating frames 604 rotate to the corresponding shaft inlet grooves 404 respectively, the driving shafts 701 extend into the moving grooves 403 under the action of the springs, and then the telescopic block 601 and the rack 602 move in the opposite direction, causing the rotating frame 604 to rotate in the opposite direction, and the moving grooves 403 and the moving seats 402 are pulled to move away from the vertical partitions 300 by the driving shafts 701, thereby driving the oil filter plate 400 to move, and performing the operation of dropping the slag;

[0066] When the slag falls, the driving shaft 701 on the rotating frame 604 moves relative to the moving groove 403 to the shaft outlet groove 405, and the driving shaft 701 is separated from the moving groove 403 from the shaft outlet groove 405, so that the moving seat 402 drives the oil filter plate 400 back to its original position under the action of the spring, and the bottom of the pressing groove is closed again;

[0067] Then the rotating frame 604 continues to rotate toward the moving seat 402 on the other side, so as to achieve connection with the moving groove 403 on this side, and then the moving operation of the oil filter plate 400 on the other side can be achieved in the same way.

[0068] Among them, Figure 1 As shown, the pressing assembly includes a horizontal pressing plate 201 slidably connected to the pressing groove, and two parallel fixing frames 200 are arranged above the oil pressing box 100, each fixing frame 200 is located above the two pressing plates 201, and two vertical pressing rods 202 are symmetrically fixed on the top of the pressing plate 201, as shown in FIG. Figure 2 As shown, a vertical guide cylinder 204 is fixed at the position corresponding to the pressing rod 202 on each fixing frame 200, the top end of the pressing rod 202 passes through the guide cylinder 204 and is fixed with an end plate 205, and a horizontal lever 203 is fixed on one side of the pressing rod 202;

[0069] like Figure 2As shown, a swing seat 206 is rotatably connected in the middle of the fixed frame 200, and inclined swing arms 207 are symmetrically fixed on both sides of the lower part of the swing seat 206, and an inclined first hydraulic telescopic rod 209 is rotatably connected to one of the swing arms 207, and the top of the first hydraulic telescopic rod 209 is rotatably connected to the bottom of the fixed frame 200, and a shifting groove 208 is provided on the swing arm 207 along the length direction, and the shifting rod 203 is slidably connected in the corresponding shifting groove 208.

[0070] When one of the pressing grooves is performing the pressing operation, the first hydraulic telescopic rod 209 extends, driving the rocking arm 207 and the rocking seat 206 to rotate to one side, thereby driving the lever 203 to move downward through the lever slot 208 on the rocking arm 207, thereby causing the two pressing rods 202 to move accordingly, and driving the corresponding pressing plates 201 to move downward to press the material in the pressing groove; then the first hydraulic telescopic rod 209 shortens, causing the rocking seat 206 and the rocking arm 207 to rotate back to their original positions, and continue to rotate to the other side, thereby causing the pressing plate 201 on the other side to move downward; therefore, through the extension or shortening of the first hydraulic telescopic rod 209, the two pressing plates 201 are moved downward in turn, so that the two pressing grooves can perform the pressing operation in turn, and the loading groove is performed when the pressing plate 201 on one side moves upward, and the pressing operation is performed when the pressing plate 201 on the other side moves downward.

[0072] When it is necessary to open the feed slot 305 on one side, the corresponding motor is used to drive the feed plate 302 on that side to rotate. During the rotation, when the side edge of the feed plate 302 is out of contact with the first material table 303 and the second material table 304, the material in the storage tank moves along the inclined surface of the first material table 303 to the feed slot 305 on that side, and then as the feed plate 302 rotates, the material is quickly pushed out, passes through the feed slot 305, and falls onto the oil filter assembly, completing the loading operation of the corresponding side pressing slot, and the pressing slot on the other side is loaded in the same way.

[0073] Among them, Figure 1As shown, the scraper assembly includes a scraper plate 503 slidably connected to the slag trough 500, the shape of the lower side of the scraper plate 503 is adapted to the shape of the slag trough 500, and a movable seat 402 is provided in the middle of the upper part of the scraper plate 503, as shown in FIG.
