Description

Technical Field

[0001] This utility model relates to the technical field of edible oil pressing equipment, and in particular to a novel grinding rod for secondary pressing. Background Technology

[0002] In the edible oil production sector, the secondary pressing process is a key step in improving the yield and quality of premium edible oils. However, the grinding rods in traditional secondary pressing equipment have significant technical bottlenecks, which severely restrict production efficiency and product quality.

[0003] In the secondary pressing stage of edible oil production, traditional grinding rods are poorly adapted to the second pressing plate, which easily leads to the accumulation of rapeseed raw materials on the side wall of the box, resulting in the raw materials not being able to fully participate in the pressing, thus limiting the oil yield and production efficiency. To address this issue, we propose a new type of grinding rod for secondary pressing. Utility Model Content

[0004] The purpose of this invention is to provide a novel grinding rod for secondary pressing, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel grinding rod for secondary pressing includes a grinding rod body with a spiral grinding groove on its outer surface and a heating channel on its upper surface. A first bearing is fixedly embedded on the upper surface of the grinding rod body, and an inlet connector is fixedly installed on the inner ring of the first bearing. A second bearing is fixedly embedded on the bottom surface of the grinding rod body, and an outlet connector is fixedly installed on the inner ring of the second bearing. A connecting assembly is fixedly installed on the upper surface of the grinding rod body.

[0007] In a further embodiment, the connecting assembly includes a set of fixing blocks, an annular disk, and a set of limiting bolts. Each fixing block has a slot and a first limiting hole on its outer surface. A spline is fixedly installed on the upper surface of the annular disk, and a set of connecting plates is fixedly installed on the bottom surface of the annular disk.

[0008] In a further embodiment, each of the connecting plates has a second limiting hole on its outer surface, the bottom end of each connecting plate is inserted into the interior of the slot, one end of each limiting bolt passes through the first limiting hole and the second limiting hole and extends to the outside of the fixing block, and a limiting nut is threaded onto the outer surface of one end of each limiting bolt.

[0009] In a further embodiment, the inlet connector includes a first connecting pipe, a first connecting plate is fixedly installed at the top end of the first connecting pipe, and a set of first assembly holes arranged in an annular pattern are formed on the upper surface of the first connecting plate.

[0010] In a further embodiment, a first annular groove is formed on the upper surface of the first connecting plate, and a first annular pad is fixedly installed on the inner wall of the first annular groove.

[0011] In a further embodiment, the outlet connector includes a second connecting pipe, the bottom end of which is fixedly mounted with a second connecting disc, and the bottom surface of the second connecting disc is provided with a set of second assembly holes arranged in annularly.

[0012] In a further embodiment, a second annular groove is formed on the bottom surface of the second connecting plate, and a second annular pad is fixedly installed on the inner wall of the second annular groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device designs the grinding rod body in a frustum shape, allowing its outline to match the inner wall of the secondary pressing plate in the pressing equipment. This prevents raw materials from accumulating on the side walls of the chamber. Spiral grinding grooves on the outer surface of the grinding rod body gradually compress and break down the raw materials, promoting continuous oil extraction. A heating channel on the upper surface of the grinding rod body allows for easy temperature regulation when heat transfer oil or coolant flows through, ensuring the grinding rod body maintains a suitable temperature and optimizing oil extraction.

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.

[0025] Please see Figure 1-6 This utility model discloses a novel grinding rod for secondary pressing, comprising a grinding rod body 2, a spiral grinding groove 3 on the outer surface of the grinding rod body 2, a heating channel 6 on the upper surface of the grinding rod body 2, a first bearing 7 fixedly embedded on the upper surface of the grinding rod body 2, an inlet connector 5 fixedly installed on the inner ring of the first bearing 7, a second bearing 8 fixedly embedded on the bottom surface of the grinding rod body 2, an outlet connector 1 fixedly installed on the inner ring of the second bearing 8, and a connecting component 4 fixedly installed on the upper surface of the grinding rod body 2. The grinding rod body 2 is frustum-shaped, and its outer contour matches the inner wall contour of the secondary pressing plate of the pressing equipment. By opening the spiral grinding groove 3 on the outer surface of the grinding rod body 2, the raw material can be crushed and squeezed while being pushed, promoting oil release. By opening the heating channel 6 on the upper surface of the grinding rod body 2, the operator can inject heat transfer oil or cooling water into the heating channel 6 through the inlet connector 5 and out through the outlet connector 1, thereby regulating the temperature of the grinding rod body 2, pressing the raw material at a suitable temperature, and optimizing the oil extraction effect.

[0026] The connecting assembly 4 includes a set of fixing blocks 403, an annular disk 402, and a set of limiting bolts 406. Each fixing block 403 has a slot 407 and a first limiting hole 409 on its outer surface. A spline 401 is fixedly installed on the upper surface of the annular disk 402, and a set of connecting plates 404 are fixedly installed on the bottom surface of the annular disk 402. Each connecting plate 404 has a second limiting hole 408 on its outer surface, and the bottom end of each connecting plate 404 is inserted into the slot 407. One end of each limiting bolt 406 passes through the first limiting hole 409 and the second limiting hole 408 and extends to the outside of the fixing block 403. The outer surface of each of the 06 ends is threaded with a limit nut 405. By installing a spline 401 on the upper surface of the annular disc 402, power can be transmitted when the outer surface of the spline 401 meshes with the drive mechanism of the grinding equipment. By inserting the bottom end of each connecting plate 404 into the slot 407, the spline 401 can drive the grinding rod body 2 to rotate when it rotates. By passing one end of each limit bolt 406 through the first limit hole 409 and the second limit hole 408 and threadedly connecting it with the limit nut 405, the multiple connecting plates 404 are firmly fixed together with the multiple fixing blocks 403.

[0027] The inlet connector 5 includes a first connecting pipe 505, with a first connecting plate 504 fixedly installed at the top end of the first connecting pipe 505. A set of annularly arranged first mounting holes 503 are formed on the upper surface of the first connecting plate 504. A first annular groove 501 is formed on the upper surface of the first connecting plate 504, and a first annular gasket 502 is fixedly installed on the inner wall of the first annular groove 501. The outlet connector 1 includes a second connecting pipe 101, with a second connecting plate 102 fixedly installed at the bottom end of the second connecting pipe 101. A set of annularly arranged second mounting holes 105 are formed on the bottom surface of the second connecting plate 102. A second annular groove 103 is formed on the bottom surface of the second connecting plate 102, and a first annular gasket 502 is fixedly installed on the inner wall of the second annular groove 103. The second annular gasket 104, by opening a set of annularly arranged first assembly holes 503 on the upper surface of the first connecting plate 504, can assemble the first connecting plate 504 with one end of the upper infusion tube. By installing the first annular gasket 502 on the inner wall of the first annular groove 501, the sealing performance at the connection between the first connecting plate 504 and the upper infusion tube can be effectively improved. By opening a set of annularly arranged second assembly holes 105 on the bottom surface of the second connecting plate 102, the second connecting plate 102 can be assembled with one end of the lower infusion tube. By installing the second annular gasket 104 on the inner wall of the second annular groove 103, the sealing performance at the connection between the second connecting plate 102 and the lower infusion tube can be effectively improved.

[0028] The working principle of this utility model is as follows:

[0029] First, the staff connects the spline 401 to the drive mechanism of the pressing equipment. Then, the staff fixes the inlet connector 5 and the outlet connector 1 to the two liquid inlet pipes of the heating device. After the heating device is started, the heat transfer oil or cooling water can flow inside the heating channel 6. When the pressing equipment is started, the drive mechanism of the pressing equipment can drive the grinding rod body 2 to rotate through the spline 401. When the grinding rod body 2 rotates, the spiral grinding groove 3 can gradually compress and crush the raw material, thereby promoting the continuous precipitation of oil.
