Description

Technical Field

[0001] The utility model relates to the technical field of purification devices, in particular to a plant squeezing and purification device. Background Art

[0002] Plant pressing and purification refers to the process of extracting oil or other useful components from plant raw materials by pressing. In grain and oil production, a common type of plant pressing and purification is grain and oil pressing and extraction. This extraction method is to put the plant raw materials (such as soybeans, rapeseed, peanuts, etc.) that have been pre-treated by crushing and baking into a press, and squeeze out the oil in the plant raw materials through mechanical force or hydraulic pressure to obtain vegetable oil.

[0003] Existing grain and oil pressing and extraction devices generally include a filter cartridge, an oil collection barrel and a pressing mechanism. The pressing mechanism includes a hydraulic cylinder. A pressing plate that matches the filter cartridge is installed at the front end of the hydraulic cylinder. During pressing and extraction, the filter cartridge is placed in the oil collection barrel and placed directly below the pressing plate. Then, plant raw materials are placed in the filter cartridge, and then the hydraulic cylinder is started to drive the pressing plate into the filter cartridge to press the raw materials. The oil produced by the pressing passes through the filter cartridge into the oil collection barrel, thereby completing the grain and oil pressing and extraction operation.

[0004] However, the above patent still has the following deficiencies during use:

[0005] After the pressing is completed, raw material residues are usually attached to the pressing surface of the pressing plate. The residues attached to the pressing surface of the pressing plate will make the pressure transmission during the pressing process poor, thereby affecting the oil extraction efficiency of subsequent pressing work.

[0032] The pressing plate assembly 5 includes a second pressing plate 13 and a first pressing plate 12. A lifting driving member is fixedly installed at the middle position of the top surface of the second pressing plate 13. The telescopic end of the lifting driving member slides through the second pressing plate 13 to the bottom of the second pressing plate 13 and is fixedly connected to the first pressing plate 12 located directly below the second pressing plate 13. A rotating connecting member used in conjunction with the flange 17 is also fixedly installed at the center position of the top surface of the second pressing plate 13, and the rotating connecting member is wrapped around the periphery of the cylinder 19.

[0033] A plurality of evenly distributed lifting columns 14 are fixedly connected to the bottom surface of the pressure plate 2 13, and a plurality of through holes 20 equal in number to the plurality of lifting columns 14 are opened on the top surface of the pressure plate 1 12, and the plurality of through holes 20 are respectively aligned with the plurality of lifting columns 14, and the bottom ends of the plurality of lifting columns 14 are respectively slidably inserted into the plurality of through holes 20.

[0034] The rotating connecting member is fixedly mounted on the hollow column 16 at the center of the top surface of the second pressure plate 13, and the telescopic end of the hydraulic cylinder 4 can be rotated and slid through the top of the hollow column 16 to the inside of the hollow column 16. The top surface of the second pressure plate 13 and the inner top surface of the hollow column 16 are also provided with an annular groove 2 which is coaxial with the annular groove on the flange 17;

[0035] A plurality of balls 18 are rollingly clamped between the annular groove 2 and the corresponding annular groove 1 on the flange 17. Under the limiting action of the plurality of balls 18 in the upper and lower layers, the flange 17 is located in the hollow column 16 at an intermediate position between the top end of the hollow column 16 and the top surface of the pressure plate 2 13, and a rotational connection between the hydraulic cylinder 4 and the pressure plate 2 13 is realized.

[0036] In the rotating connection assembly, through the matching arrangement between the hollow column 16, the ball 18 and the flange 17 at the telescopic end of the hydraulic cylinder 4, the connection between the hydraulic cylinder 4 and the pressure plate 13 can withstand a large axial force, and the hydraulic cylinder 4 and the pressure plate 13 can rotate relative to each other; by rotating the pressure plate 13, the residue at the bottom of the pressure plate 12 can be subjected to the action of centrifugal force, thereby improving the residue removal effect.

[0037] Among them, the lifting drive component includes a cylinder 19 fixedly installed in the middle position of the top surface of the pressure plate 13, the fixed part of the cylinder 19 is located in the cavity 11 of the hydraulic cylinder 4, the telescopic end of the cylinder 19 slides through the pressure plate 13 to the bottom of the pressure plate 13, and is fixedly connected to the pressure plate 1 12.

[0038] When the utility model is in use:

[0039] In the squeezing state, the cylinder 19 is in an extended state, at which time there is a gap between the pressure plate 12 and the pressure plate 2 13, and the bottom end of the lifting column 14 is flush with the bottom surface of the pressure plate 12, so that the bottom surface of the pressure plate 12 is in a flat state; during squeezing, the hydraulic cylinder 4 is controlled to drive the squeezing plate assembly 5 to descend into the filter cartridge 6, squeezing the plant material in the filter cartridge 6, and the squeezed oil passes through the filter cartridge 6 into the oil collection barrel 7 to be collected;

[0040] After the pressing is completed, the hydraulic cylinder 4 is controlled to drive the pressing plate assembly 5 to rise and reset, and then the raw material residue attached to the bottom surface of the pressing plate 12 is cleaned. Specifically, the cylinder 19 is controlled to drive the pressing plate 12 to reciprocate. During the process, when the pressing plate 12 rises, the bottom ends of the plurality of jacking columns 14 are moved to the bottom of the pressing plate 12 through the through holes 20, and the residue on the bottom surface of the pressing plate 12 is ejected, so that the residue falls from the bottom surface of the pressing plate 12; by reciprocating the lifting and lowering of the pressing plate 12, the cleaning effect is improved. After the cleaning is completed, the cylinder 19 is controlled to reset to the extended state. At this time, the bottom end of the jacking column 14 is flush with the bottom surface of the pressing plate 12, ready for the next pressing action;

[0041] Therefore, in the press plate assembly 5 of the utility model, through the coordinated arrangement of the press plate 12, the press plate 12 and the lifting column 14, and then through the lifting action of the cylinder 19, the press plate assembly 5 has the function of automatic slag removal, and can quickly complete the cleaning of the residue on the bottom surface of the press plate 12 before the press plate assembly 5 performs the next pressing action, thereby avoiding affecting the oil extraction efficiency of the subsequent pressing work.

[0044] A limit plate 9 is fixedly mounted on one end of the scraper strip 8 away from the U-shaped mounting frame 3, and a handle 10 for pushing and pulling the scraper strip 8 is fixedly mounted on one side of the limit plate 9 away from the scraper strip 8.

[0045] Among them, two handles 15 used in conjunction with the scraping assembly are fixedly installed on the top surface of the pressure plate 13. The handles 15 are used to rotate the pressure plate 13 and the hydraulic cylinder 4, so as to cooperate with the scraping assembly to clean the raw material residue attached to the bottom surface of the pressure plate 12.

[0046] After the pressing plate assembly 5 is automatically deslagging, some residue may still exist on the bottom surface of the pressing plate 12. At this time, the scraper bar 8 is pushed by the handle 10, and the scraper bar 8 passes under the pressing plate 12. Then the hydraulic cylinder 4 is controlled to lower the pressing plate assembly 5 to a certain distance, so that the bottom surface of the pressing plate 12 is in contact with the top surface of the scraper bar 8. Then the pressing plate 13 is rotated by the handle 2 15. The rotation of the pressing plate 13 will drive the pressing plate 12 to rotate synchronously, thereby cooperating with the scraper bar 8 to further clean the residue on the bottom surface of the pressing plate 12. Therefore, by setting the scraping assembly, the effect of cleaning the residue on the bottom surface of the pressing plate 12 can be further improved, thereby improving the practicability of the device.

When the filter cartridge 6 is in the installed state, the bottom ends of the four positioning rods 21 are slidably inserted into the four positioning seats 22 respectively.

[0050] By cooperating with the positioning rod 21 and the positioning seat 22, the filter cartridge 6 can be positioned during installation so that the filter cartridge 6 is directly below the pressing plate assembly 5, thereby ensuring the accuracy and stability of docking between the pressing plate assembly 5 and the filter cartridge 6 during the descending process; by setting the leakage hole 23, grease will not be stored in the positioning seat 22, thereby avoiding affecting the docking operation between the positioning rod 21 and the positioning seat 22.
