Description

Technical Field

[0001] This utility model relates to the field of edible oil processing technology, specifically to a grading device for edible oil processing. Background Technology

[0002] The common processing and refining method for edible oil involves dehulling and crushing the raw materials, then using a solvent extraction method followed by Soxhlet extraction to prepare crude oil. Soxhlet extraction is a highly efficient and low-cost method for preparing crude oil. The oil is then refined under reduced pressure distillation to obtain high-grade edible oil. Many oilseeds can be used to produce edible oil, such as sunflower seeds, cottonseed, olives, palm seeds, rapeseed, safflower seeds, sesame seeds, macadamia nuts, Mongolian nuts, sacha inchi, watermelon seeds, gourd seeds, buffalo gourd seeds, winter squash seeds, and pumpkin seeds. After dehulling and crushing the oilseeds, Soxhlet extraction is performed. However, the crushed kernels must be graded by size before further extraction processes can proceed.

[0003] In the prior art, a multi-layer grading device for edible oil production, with publication number "CN221311402U", relates to the field of edible oil production technology. It includes a processing box, with a hollow top cover on the upper outer surface. A feeding hopper is located on the upper outer surface of the top cover, and an electric rotating shaft is installed inside the feeding hopper. Three sets of stirring rods are provided on the outer wall of the electric rotating shaft. Six through holes are provided at the bottom of the feeding hopper. Three sets of push-pull frames are vertically arranged on the front outer surface of the processing box. Limit bolts are provided at both ends of the outer surface of each push-pull frame. Two sets of mounting brackets are provided on the inner outer surface of each push-pull frame, connecting to the inside of the processing box. Each set of mounting brackets has four mounting slots on its outer surface. Three sets of support blocks are provided on the lower outer surface of each mounting bracket. A pull rod is provided at the rear end of each limit bolt, connecting to the inside of the processing box. A linkage shaft seat is located at the end of each pull rod on the inner wall of the processing box.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] 1. During use, the above-mentioned device can only filter the raw materials of nuts or oilseeds required for edible oil processing by shaking the filter screen plate. This will still cause the raw materials to accumulate on the filter screen plate, or can only be filtered in a small area of ​​the filter screen plate, resulting in low filtration efficiency.

[0006] 2. After the device performs graded filtration on the raw materials, the filtered raw materials need to be manually removed from the processing box, which is very cumbersome and inefficient. Utility Model Content

[0007] The purpose of this invention is to provide a grading device for edible oil processing to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A grading device for edible oil processing includes a box body, several support legs fixedly installed at the bottom of the box body, a feed hopper connected to the top of the box body, a low-speed motor fixedly installed at the top of the box body, a rotating shaft fixedly connected to the low-speed motor and passing through the entire box body, three movable slots opened inside the box body, filter screens movably mounted on the movable slots, and a discharge port opened above each movable slot and the bottom plate of the box body;

[0010] The rotating shaft is equipped with a vibration mechanism that causes the filter screen to vibrate.

[0011] The rotating shaft is equipped with a scraping mechanism for scraping the filter screen.

[0012] Preferably, the vibration mechanism includes a spiral groove and a vertical groove formed on the filter screen by a rotating shaft, the spiral groove and the vertical groove being connected, a top sleeve being slidably fitted on the rotating shaft below the filter screen, and a protruding post being fixedly provided on the inner wall of the top sleeve, the protruding post being slidably disposed in the spiral groove and the vertical groove.

[0013] Preferably, the scraping mechanism includes a sliding groove opened above the filter screen by a rotating shaft, a sliding cylinder slidably engaged with the rotating shaft at the sliding groove, an arc-shaped plate fixedly connected to the sliding cylinder, a fixing block fixedly connected to the rotating shaft above the sliding groove, and a compression spring sleeved between the rotating shaft, the sliding cylinder, and the fixing block.

[0014] Preferably, the movable groove is fixedly provided with a limiting rod, the limiting rod slides through the filter screen, and bag rings are fixedly connected between the upper and lower sides of the filter screen and the movable groove.

[0015] Preferably, the width of the spiral groove is the same as the diameter of the protrusion, and the width of the vertical groove is greater than the diameter of the protrusion and the height is less than or equal to the height of the movable groove.

[0016] Preferably, the rotating shaft is fixedly provided with an arc-shaped plate at the bottom of the housing, and the height of the sliding groove is greater than or equal to the sum of the heights of the movable groove and the sliding cylinder.

[0017] Preferably, the filter holes of the three filter screens decrease in size from top to bottom, and a discharge trough is fixedly provided on the outer wall of the box at the discharge port. An arc-shaped baffle is movably engaged between the box and the discharge trough.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. When the rotating shaft is driven to rotate clockwise by a low-speed motor, the spiral groove and vertical groove on the rotating shaft can drive the top sleeve to rise and fall spirally, thereby causing the three filter screens to vibrate up and down in the movable groove, thus filtering the raw materials on the filter screens and accelerating the filtration rate. At the same time as the rotating shaft rotates clockwise, it drives the sliding cylinder and its arc plate to rotate on the filter screen, scraping the raw materials on the filter screen and spreading the raw materials to cover the entire filter screen, thereby further improving the filtration rate and greatly improving the working efficiency of the entire device.

[0020] 2. After the equipment finishes filtering the raw materials, open the arc-shaped baffle at the discharge port, then reverse the low-speed motor to make the shaft rotate counterclockwise. The arc-shaped baffle rotates counterclockwise to scrape each layer of filter screen and the bottom of the box. Due to the special shape of the arc-shaped baffle, the raw materials filtered by each layer of filter screen and the bottom of the box can be scraped to the edge of the box and finally discharged from the discharge port, thus completing the classified collection. No manual operation is required, which is very convenient and further improves the working efficiency of the equipment. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 This utility model provides a technical solution:

[0030] Example 1:

[0031] A grading device for edible oil processing includes a housing 1, which forms a working chamber where all grading and filtration are completed. Several support legs 2 are fixedly installed at the bottom of the housing 1 to support the housing 1, facilitating the placement of collection boxes for collecting the graded and filtered raw materials below. A feed hopper 3 is connected to the top of the housing 1, through which all raw materials requiring grading and filtration are fed into the housing 1. A low-speed motor 4 is fixedly installed at the top of the housing 1, which can only rotate at low speed. The low-speed motor 4 is fixedly connected to a rotating shaft 5 that runs through the entire housing 1, so the rotating shaft 5 also passes through three filter screens 7, and their rotation does not affect each other.

[0032] The housing 1 has three movable slots 6 inside, and filter screens 7 are movably mounted on the movable slots 6. The filter screens 7 can move up and down in the movable slots 6. The filter holes of the three filter screens 7 decrease in size from top to bottom. The smaller the filter holes from top to bottom, the better the raw materials can be graded and filtered. A limit rod 18 is fixedly installed in the movable slots 6. The limit rod 18 slides through the filter screens 7 and restricts the filter screens 7 to move up and down but not rotate. The upper and lower sides of the filter screens 7 are fixedly connected to the movable slots 6. A cloth bag ring 19 is provided. The cloth bag ring 19 is designed to prevent the raw material on the filter screen 7 from entering the movable groove 6 and affecting the up and down vibration of the filter screen 7. The box body 1 has a discharge port 8 above each movable groove 6 and the bottom plate of the box body 1. A discharge groove 20 is fixedly provided on the outer wall of the box body 1 at the discharge port 8. An arc-shaped baffle 21 is movably locked between the box body 1 and the discharge groove 20. When the arc-shaped baffle 21 is pulled out, the raw material in the box body 1 can be discharged from the discharge port 8 to the discharge groove 20 and then collected.

[0033] A vibration mechanism is provided on the rotating shaft 5 to cause the filter screen 7 to vibrate. The vibration mechanism includes a spiral groove 9 and a vertical groove 10 opened on the rotating shaft 5 at the filter screen 7. The spiral groove 9 and the vertical groove 10 are connected. A top sleeve 11 is slidably fitted on the rotating shaft 5 below the filter screen 7. A protruding post 12 is fixedly installed on the inner wall of the top sleeve 11. The protruding post 12 is slidably disposed in the spiral groove 9 and the vertical groove 10. The width of the spiral groove 9 is the same as the diameter of the protruding post 12. When the rotating shaft 5 rotates clockwise, the spiral groove 9 causes the protruding post 12 to rotate and rise upward in it, thereby driving the top sleeve 11 to vibrate. The shaft 5 rotates and rises. When the protruding post 12 rotates and rises to the highest point of the spiral groove 9, which is also the highest point of the vertical groove 10, it will slide down in the vertical groove 10. The width of the vertical groove 10 is greater than the diameter of the protruding post 12 and the height is less than or equal to the height of the movable groove 6. When the protruding post 12 descends in the vertical groove 10, it takes a certain amount of time, while the shaft 5 is still rotating. Therefore, the width of the vertical groove 10 is set to be relatively wide to prevent the vertical groove 10 from jamming the protruding post 12 and preventing it from sliding down. The height of the vertical groove 10 is less than or equal to the height of the movable groove 6 to prevent the protruding post 12 from failing to rise to the highest point.

[0034] Example 2:

[0035] The rotating shaft 5 is equipped with a scraping mechanism for scraping the filter screen 7. The scraping mechanism includes a groove 13 opened above the filter screen 7 on the rotating shaft 5. The height of the groove 13 is greater than or equal to the sum of the heights of the movable groove 6 and the sliding cylinder 14, which can prevent the arc plate 15 from failing to contact the filter screen 7 when the filter screen 7 is at its lowest point in the movable groove 6. The sliding cylinder 14 is slidably mounted on the rotating shaft 5 at the groove 13. The arc plate 15 is fixedly connected to the sliding cylinder 14. A fixing block 16 is fixedly connected above the groove 13 on the rotating shaft 5. A compression spring 17 is sleeved between the slide cylinder 14 and the fixed block 16. The compression spring 17 ensures that the arc plate 15 on the slide cylinder 14 is always in contact with the filter screen 7 for scraping. The rotating shaft 5 is fixedly provided with an arc plate 15 at the bottom of the housing 1. The groove surface of the arc plate 15 is on the left and the convex surface is on the right. This ensures that the raw material is always kept on the filter screen 7 when rotating clockwise. When rotating counterclockwise, the convex surface can push the raw material on the filter screen 7 to the edge of the filter screen 7 and then discharge it from the outlet 8.

[0036] Working principle: First, the raw material to be processed is added from the feed hopper 3 into the housing 1. Then, the low-speed motor 4 is started to make the rotating shaft 5 rotate clockwise. The spiral groove 9 causes the protrusion 12 to drive the top sleeve 11 to spiral upward. Then, the top sleeve 11 pushes against the filter screen 7 and moves upward in the movable groove 6. At the same time, the filter screen 7 will push against the slide cylinder 14 and the arc plate 15 and move upward to compress the spring 17. The rotating shaft 5 will still drive the slide cylinder 14 and the arc plate 15 to rotate clockwise on the filter screen 7.

[0037] When it rises to the highest point, the protruding post 12 falls into the vertical groove 10, the top sleeve 11 and the filter screen 7 will also fall, and the compression spring 17 will return to its original position and squeeze the slide cylinder 14 and the arc plate 15 to move downward along with the filter screen 7. The arc plate 15 still rotates clockwise on the filter screen 7 along with the rotating shaft 5.

[0038] After the grading and screening are completed, pull out the arc-shaped baffle 21, and then start the low-speed motor 4 in reverse to make the rotating shaft 5 rotate counterclockwise. The arc-shaped plate 15 also rotates counterclockwise, thereby scraping the raw material from the filter screen 7 and the bottom of the box 1 to the edge, and finally discharging it from the discharge port 8.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
