Description

Technical Field

[0001] This utility model relates to the field of rapeseed oil processing technology, and in particular to a pressing and filtering device for rapeseed oil production. Background Technology

[0002] Rapeseed oil, also known as rapeseed oil or coriander oil, is an edible oil extracted from rapeseed. With social development and technological progress, machines have gradually replaced manual labor, and traditional manual oil pressing has also been replaced by machines.

[0003] Patent document CN220989931U discloses a pressing and filtering device for rapeseed oil production, including a crushing box. Feed hoppers are located on both sides of the top of the crushing box. A first motor is mounted on the top of the crushing box, and a movable shaft is fixedly connected to the output end of the first motor. Crushing blades are fixedly connected to both sides of the inner cavity of the crushing box and the surface of the movable shaft. This invention can efficiently crush rapeseed. By rotating the limiting rod until its back separates from the surface of the cover plate, removing the cover plate, and pulling out the pin upwards, the filter screen can be quickly removed for cleaning.

[0004] In practical use, the rapeseed oil filtration device proposed in the above patent documents has a horizontally fixed filter screen at the bottom for filtering and removing impurities from the pressed rapeseed oil. This not only results in an ineffective filtration area but also leads to the accumulation of filtered oil residue on the screen surface, requiring frequent manual cleaning to ensure proper filtration. Therefore, improvements to this device are necessary. Utility Model Content

[0005] This utility model discloses a pressing and filtering device for rapeseed oil production. To achieve the above-mentioned objective, this utility model adopts the following technical solution:

[0006] A pressing and filtering device for rapeseed oil production includes a filter box, a pressing mechanism for pressing rapeseed is provided on the top of the filter box, and a filter assembly is provided inside the filter box.

[0007] The filter assembly includes a linkage plate, on which arc-shaped filter plates are fixedly connected to both the front and rear surfaces.

Two movable rods are fixedly connected to the upper surface of the linkage plate, and the top ends of the movable rods extend to the outside of the filter box.

[0008] The filter box has slag discharge holes on both the front and rear surfaces. An oil slag collection box is fixedly installed outside the slag discharge holes. A return shell is fixedly installed directly below the oil slag collection box. An oil draining mesh is fixedly installed at the bottom of the oil slag collection box.

[0009] In a preferred embodiment, the inner wall of the filter box is provided with a plurality of oil drain holes, which are evenly distributed in a linear array on the inner wall of the filter box. The positions of the oil drain holes correspond to the reflux shell and are located below the arc-shaped filter plate. The position of the reflux shell corresponds to the oil residue collection box, and the oil drain mesh plate is located directly above the opening of the reflux shell.

[0010] In a preferred embodiment, a vibrating base plate is fixedly connected to the top of the movable rod, a vibrating motor is fixedly mounted on the upper surface of the vibrating base plate, a support spring is sleeved on the surface of the movable rod, the top of the support spring is fixedly connected to the lower surface of the vibrating base plate, and the bottom of the support spring is fixedly connected to the upper surface of the filter box.

[0011] In a preferred embodiment, the pressing mechanism includes a pressing box, two pressing rollers are rotatably connected to the inner wall of the pressing box, and a feed square tube is fixedly disposed between the lower surface of the pressing box and the filter box.

[0012] In a preferred embodiment, a transmission box is fixedly provided on the side of the pressing box, a drive motor is provided on the surface of the transmission box, the output shaft of the drive motor extends into the interior of the transmission box and is fixed with a drive gear, and a driven gear is rotatably provided on the inner wall of the transmission box, and the drive gear and the driven gear mesh.

[0014] As can be seen from the above, the pressing and filtering device for rapeseed oil production provided by this utility model has the following technical effects.

[0015] Firstly, by installing a filter assembly inside the filter box, the pressed rapeseed oil can be filtered using an arc-shaped filter plate. The oil residue is then concentrated and falls into the slag discharge holes on both sides of the arc-shaped filter plate, and the oil residue is collected in the oil residue collection box outside the filter box using the slag discharge holes. The oil residue can then be further drained using the oil draining mesh plate at the bottom of the oil residue collection box, and the oil drained from the oil residue can be recycled back into the filter box using the return shell, thus achieving the purpose of centralized oil residue draining and recycling.

[0016] Secondly, by setting up a linkage plate and a movable rod, the vibration motor can drive the movable rod and linkage plate to vibrate during the filtration process, thereby causing the arc-shaped filter plate to vibrate up and down inside the filter box. This can vibrate and slide off the oil residue accumulated on the surface of the arc-shaped filter plate, preventing the oil residue from adsorbing and clogging the filter screen. This eliminates the need for frequent cleaning of the filter screen by the staff and helps to improve processing efficiency. Attached Figure Description

[0028] Place the collection container below the oil outlet 9. The oil outlet 9 can be used to input the filtered rapeseed oil into the external collection container.

[0029] It should be noted that the pressing mechanism 2 includes a pressing box 201, and two pressing rollers 202 are rotatably connected to the inner wall of the pressing box 201. A feed square tube 203 is fixedly installed between the lower surface of the pressing box 201 and the filter box 1.

[0030] It should be further explained that a transmission box 204 is fixedly provided on the side of the pressing box 201, and a drive motor 205 is provided on the surface of the transmission box 204. The output shaft of the drive motor 205 extends into the interior of the transmission box 204 and is fixed with a drive gear. A driven gear is rotatably provided on the inner wall of the transmission box 204, and the drive gear and the driven gear mesh.

[0031] The shafts of the two pressing rollers 202 extend into the interior of the transmission box 204 and are fixedly connected to the surfaces of the drive gear and the driven gear, respectively. The drive motor 205 drives the drive gear and the driven gear to rotate, thereby driving the two pressing rollers 202 to rotate in opposite directions, which can press the rapeseed.

[0032] Reference Figure 3 and Figure 4 In a preferred embodiment, the filter assembly 3 includes a linkage plate 301, with arc-shaped filter plates 302 fixedly connected to both the front and rear surfaces of the linkage plate 301. A rubber connecting strip 303 is fixedly connected between the end of the arc-shaped filter plate 302 away from the linkage plate 301 and the inner wall of the filter box 1. Two movable rods 304 are fixedly connected to the upper surface of the linkage plate 301, with the top ends of the movable rods 304 extending to the outside of the filter box 1.

[0033] By setting the rubber connecting belt 303, the arc-shaped filter plate 302 can be limited when it vibrates up and down, and the sliding oil residue can be guided to the outside of the filter box 1 by the rubber connecting belt 303.

[0034] It should be noted that a vibrating base plate 305 is fixedly connected to the top of the movable rod 304, and a vibrating motor 306 is fixedly installed on the upper surface of the vibrating base plate 305. A motor dust cover is installed on the surface of the filter box 1. The position of the motor dust cover corresponds to that of the vibrating motor 306, and heat dissipation holes are opened on the surface of the motor dust cover.

[0035] Reference Figure 5 It should be further explained that a support spring 307 is sleeved on the surface of the movable rod 304. The top end of the support spring 307 is fixedly connected to the lower surface of the vibrating base plate 305, and the bottom end of the support spring 307 is fixedly connected to the upper surface of the filter box 1.

[0036] The support spring 307 can be used to support and limit the bottom of the vibration base plate 305, and can make the vibration base plate 305 vibrate up and down.

[0037] It is worth noting that by setting up the linkage plate 301, the movable rod 304, and the vibration motor 306, the vibration motor 306 can drive the movable rod 304 and the linkage plate 301 to vibrate during the rapeseed oil filtration process. This causes the arc-shaped filter plate 302 to vibrate up and down inside the filter box 1, which can vibrate and slide off the oil residue accumulated on the surface of the arc-shaped filter plate 302, preventing the oil residue from adsorbing and clogging the filter screen. This eliminates the need for frequent cleaning of the filter screen by the staff and helps to improve processing efficiency.

[0038] The filter box 1 has slag discharge holes 4 on both the front and rear surfaces. An oil slag collection box 5 is fixedly installed outside the slag discharge holes 4.

The position of the oil drain holes 8 corresponds to the return shell 6, and the oil drain holes 8 are located below the arc-shaped filter plate 302.

[0040] It should be noted that the position of the reflux shell 6 corresponds to that of the oil residue collection box 5, and the oil draining screen 7 is located directly above the opening of the reflux shell 6.

[0041] It is worth noting that by setting a filter assembly 3 inside the filter box 1, the pressed rapeseed oil can be filtered by the arc-shaped filter plate 302, allowing the oil residue to slide into the slag discharge holes 4 on both sides of the arc-shaped filter plate 302, and the oil residue is collected into the oil residue collection box 5 outside the filter box 1 by the slag discharge holes 4. The oil residue can be drained a second time by the oil draining mesh plate 7 at the bottom of the oil residue collection box 5, and the oil drained from the oil residue can be recovered into the filter box 1 by the return shell 6, thus achieving the purpose of centralized oil residue draining and recovery.

[0042] Working principle: When in use, rapeseed is first put into the pressing box 201 through the feed square tube 203. Then, the rapeseed is pressed by two pressing rollers 202. The oil and oil residue produced after pressing enter the surface of the arc-shaped filter plate 302 inside the filter box 1. The oil is filtered by the arc-shaped filter plate 302. The oil residue slides down to the slag discharge holes 4 on both sides under the action of vibration. The oil residue is collected and drained by the oil residue collection box 5. The drained oil is recycled into the filter box 1, achieving the purpose of automatic separation and collection of oil residue.
