Description

Technical Field

[0001] This utility model relates to the field of pressing device technology, and in particular to a pressing device for plant extraction. Background Technology

[0002] The pressing device is used to extract vegetable oil or juice. It consists of a worktable, hopper, pressing cage, screw press, motor unit, drive shaft, and discharge plate. When using the pressing device to extract peanut oil, continuous feeding and propulsion occur: pre-treated peanuts enter the pressing chamber from the hopper. The controller starts the first motor, which is connected to the drive shaft via a reducer and coupling, causing the screw press to rotate. This causes the screw blades to continuously propel the material forward. Compression of the pressing chamber space occurs: the root diameter of the screw press gradually increases, while the pitch gradually decreases, resulting in a continuous reduction in the pressing chamber volume and increasing mechanical pressure on the material. Frictional pressure increase occurs: friction between the material and the screw press and the inner wall of the pressing chamber generates resistance, causing relative movement between the material particles, further squeezing out the oil. Frictional heat effect occurs: the friction generates high temperatures, causing protein denaturation, disrupting the colloidal structure, reducing oil viscosity, and increasing oil yield. Oil separation and slag discharge occur: the squeezed oil is filtered through the gaps in the pressing cage and falls onto the discharge plate for collection; the residue is pressed into cakes and automatically discharged from the end of the pressing shaft.

[0003] In their daily work, the inventors discovered that when the pressing device is in use, although the pressed oil is filtered and collected through the gaps in the pressing cage, some crushed peanut fragments still flow out with the oil. In order to filter out the fragments, a filter cover is usually set on the outer surface of the pressing cage to intercept the fragments. However, the fragments accumulate in the filter cover for a long time, which may cause the filter cover mesh to be blocked, and thus may affect the filtration efficiency of the filter cover for the pressed oil. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in actual use, although the squeezed oil is filtered and collected through the gaps in the press cage, crushed peanut fragments still flow out with the oil. In order to filter the fragments, a filter cover is usually set on the outer surface of the press cage to intercept the fragments. However, the fragments accumulate in the filter cover for a long time, which may cause the filter cover mesh to be blocked, thus affecting the filtration efficiency of the filter cover for the squeezed oil. Therefore, a pressing device for plant extraction is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pressing device for plant extraction, comprising a pressing cage mounted on a workbench, a hopper fixedly connected to the upper end of the pressing cage, one end of the pressing cage being closed and the other end open, a pressing screw rotatably connected to the inner wall of the pressing cage via a bearing, a mounting frame fixedly connected to one end of the workbench, a first motor mounted on one side of the mounting frame, a drive shaft fixedly connected to one end of the pressing screw, the drive shaft and the workbench being connected via a bearing, the first motor controlling the rotation of the drive shaft, a feeding plate fixedly connected to one end of the workbench, the feeding plate being located below the pressing cage, a filter assembly provided on the arc surface of the pressing cage, the filter assembly comprising a filter cover fixedly connected to the arc surface of the pressing cage, a plurality of evenly distributed filter holes being opened below the arc surface of the filter cover, a rotating rod provided on the inner wall of the filter cover, a drive mechanism for driving the rotating rod to rotate provided on the back of the filter cover, a mounting rod slidably connected to the inner wall of the rotating rod, bristles fixedly connected to the lower end of the mounting rod, and a discharge port fixedly connected to the arc surface of the filter cover.

[0006] The effect achieved by the above components is as follows: by setting up the filter assembly, when it is necessary to clean the peanut fragments accumulated on the filter cover, the drive mechanism causes the rotating rod to rotate, causing the bristles on the mounting rod to rotate accordingly, thereby the bristles sweep and clean the peanut fragments accumulated on the filter cover. The swept fragments are swept out from the discharge port, thus achieving the effect of cleaning the peanut fragments accumulated on the filter cover as much as possible.

[0007] Preferably, the drive mechanism includes a gear ring rotatably connected to both sides of the inner wall of the filter cover by means of bearings, the gear ring being fixedly connected to the rotating rod, and the inner arc surface of the gear ring being meshed with a gear.

[0008] The effect achieved by the above components is that the gear rotates, causing the gear ring to rotate, which in turn causes the rotating rod to rotate.

[0009] Preferably, a second motor is installed on the back of the filter cover, and the second motor controls the rotation of the gear.

[0010] The effect achieved by the above components is as follows: the second motor is started by the controller, and the second motor is connected to the gear through the reducer and coupling, so that the gear rotates.

[0011] Preferably, a collection box that can be detachably connected by screws is provided on one side of the discharge port.

[0012] The effect achieved by the above components is to collect the peanut crumbs swept out by the brush by setting up a collection box.

[0013] Preferably, a spring is fixedly connected to the upper end of the mounting rod, and the other end of the spring is fixed to the rotating rod.

[0014] The effect achieved by the above components is as follows: by setting a spring, the brush bristles contact the filter cover, the spring is in a compressed state, and its reverse force pushes the mounting rod, so that the brush bristles fully contact the filter cover.

[0015] Preferably, the lower end of the bristles is provided with a hook shape.

[0016] The effect achieved by the above components is that, by setting the hook shape, the bristles hook out the debris from the filter screen mesh.

[0017] Preferably, the inner wall of the workbench is provided with an auger that is rotatably connected by a bearing, and the arc surface of the auger is fixedly connected to a first sprocket.

[0018] The effect achieved by the above components is that the cake formed by pressing the residue falls from the end of the press shaft onto the inner wall of the worktable, the first sprocket rotates, causing the auger to rotate, thereby pushing the cake formed by pressing the residue out of the inner wall of the worktable.

[0019] Preferably, a second sprocket is fixedly connected to the arc surface of the drive shaft, and a chain is provided between the first sprocket and the second sprocket.

[0020] The effect achieved by the above components is that the rotation of the drive shaft causes the second sprocket to rotate, and the first sprocket rotates through the chain drive.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by setting up a filter assembly, when it is necessary to clean the peanut fragments accumulated on the filter cover, the driving mechanism causes the rotating rod to rotate, causing the bristles on the mounting rod to rotate as well. The bristles then sweep away the peanut fragments accumulated on the filter cover, and the swept fragments are discharged from the discharge port. This achieves the effect of cleaning the peanut fragments accumulated on the filter cover as much as possible. This solves the problem that when the oil is extracted and collected through the gaps in the press cage, peanut fragments still flow out with the oil. In order to filter the fragments, a filter cover is usually set on the outer surface of the press cage to intercept the fragments. However, if the fragments accumulate inside the filter cover for a long time, it may cause the filter cover mesh to become blocked, which may affect the filtration efficiency of the filter cover for the extracted oil.

A hopper 4 is fixedly connected to the upper end of the pressing cage 3. One end of the pressing cage 3 is closed and the other end is open. A pressing screw 10 is provided on the inner wall of the pressing cage 3 and is rotatably connected by a bearing. A mounting frame 6 is fixedly connected to one end of the workbench 1.

A filter assembly 2 is provided on the arc surface of the pressing cage 3.

[0032] Reference Figure 4 and Figure 5 as well as Figure 6As shown, in this embodiment: the filter assembly 2 includes a filter cover 21 fixedly connected to the arc surface of the press cage 3. Multiple evenly distributed filter holes 22 are provided below the arc surface of the filter cover 21. A rotating rod 23 is provided on the inner wall of the filter cover 21.

Brush bristles 26 are fixedly connected to the lower end of the mounting rod 25. A discharge port 29 is fixedly connected to the arc surface of the filter cover 21. By setting... When the peanut fragments accumulated on the filter cover 21 need to be cleaned, the drive mechanism 24 rotates the rotating rod 23, causing the bristles 26 on the mounting rod 25 to rotate accordingly. The bristles 26 then sweep away the peanut fragments accumulated on the filter cover 21, and the swept fragments are discharged from the discharge port 29, thus achieving the effect of cleaning the peanut fragments accumulated on the filter cover 21 as much as possible. The drive mechanism 24 includes toothed rings 241 rotatably connected to both sides of the inner wall of the filter cover 21 via bearings. The toothed rings 241 are fixed to the rotating rod 23. A gear 242 is meshed with the inner arc surface of the gear ring 241. Rotation of the gear 242 causes the gear ring 241 to rotate, which in turn causes the rotating rod 23 to rotate. A second motor 243 is mounted on the back of the filter cover 21. The second motor 243 controls the rotation of the gear 242. The second motor 243 is started by a controller and connected to the gear 242 via a reducer and coupling, causing the gear 242 to rotate. A collection box 21, detachably connected to the discharge port 29 via screws 211, is provided on one side of the discharge port 29. 0.

The arc surface of the auger 7 is fixedly connected to a first sprocket 12. The cake formed by pressing the residue falls from the end of the press shaft onto the inner wall of the workbench 1.

The arc surface of the drive shaft 9 is fixedly connected to a second sprocket 11. A chain 13 is provided between the first sprocket 12 and the second sprocket 11. The rotation of the drive shaft 9 causes the second sprocket 11 to rotate, and the first sprocket 12 rotates through the transmission of the chain 13.

[0034] Working principle:

[0035] When using a pressing device (model 6YL-95 screw oil press) to extract peanut oil, continuous feeding and propulsion occur: pre-treated peanuts enter the pressing chamber from the hopper 4. The first motor 5 is started by the controller. The first motor 5 is connected to the transmission shaft 9 through a reducer and coupling, causing the screw 10 to rotate. This causes the spiral blades to continuously propel the material forward, compressing the pressing chamber space: the root diameter of the screw 10 gradually increases, while the pitch gradually decreases, resulting in a continuous reduction in the pressing chamber volume. This creates increasing mechanical pressure and friction on the material. Pressurization: The friction between the material and the screw press 10 and the inner wall of the pressing chamber generates resistance, causing relative movement between the material particles, further squeezing out the oil. Frictional heat effect: The friction generates high temperature, causing protein denaturation, destroying the colloidal structure, reducing oil viscosity, and increasing oil yield. Oil separation and slag discharge: The squeezed oil is filtered out from the gaps in the pressing cage 3 and falls onto the feeding plate 8 for collection; the residue is pressed into cakes and automatically discharged from the end of the pressing shaft. When it is necessary to clean the peanut fragments accumulated on the filter cover 21, the second power is activated by the controller. The second motor 243 is connected to the gear 242 via a reducer and coupling, causing the gear 242 to rotate, which in turn causes the gear ring 241 to rotate, which in turn causes the rotating rod 23 to rotate, causing the brush bristles 26 on the mounting rod 25 to rotate as well. The brush bristles 26 then sweep away the peanut fragments accumulated on the filter cover 21. The swept fragments are then discharged from the discharge port 29, thus achieving the goal of cleaning the peanut fragments accumulated on the filter cover 21 as much as possible. A collection box 210 is provided to collect the peanut fragments swept away by the brush bristles 26. A spring mechanism is also included. Spring 28 and brush bristles 26 contact the filter cover 21. Spring 28 is in a compressed state, and its reverse force pushes the mounting rod 25, so that brush bristles 26 fully contact the filter cover 21. By setting hook shape 27, brush bristles 26 hook out the fragments from the mesh of filter cover 21. The cake formed by the residue falls from the end of the press shaft to the inner wall of the worktable 1. The drive shaft 9 rotates, causing the second sprocket 11 to rotate. With the help of chain 13, the first sprocket 12 rotates, causing the auger 7 to rotate, thereby pushing the cake formed by the residue out of the inner wall of the worktable 1.
