Description

Technical Field

[0001] This utility model relates to the technical field of centrifugal separation devices, specifically a centrifugal separation device for producing powdered oils. Background Technology

[0002] Powdered grease processing is a technology that converts grease into powdered or granular products. During the processing, it is usually necessary to separate the grease from the corresponding materials. Centrifugal separation devices are typically used to separate grease and related materials based on the centrifugal principle.

[0003] A search revealed Chinese patent application CN202220172013.7, which discloses a centrifugal separation device for producing powdered oil using an enzymatic method. The device includes a cylindrical body with a support frame fixed to the bottom wall and a top cover fixed to the top. A centrifuge cylinder, rotatably connected to the cylindrical body, is located inside the body. Multiple through holes are formed on the side wall of the centrifuge cylinder, and an oil-absorbing pad is fixed to the side wall. This invention uses a driving device to rotate the centrifuge cylinder, separating and centrifuging the materials inside. The oil-absorbing pad absorbs and permeates the oil adhering to soybeans and plant residues onto the inner wall of the centrifuge cylinder, facilitating the separation of the oil through the through holes during centrifugation. This allows for more comprehensive oil separation. Furthermore, a squeezing device further compresses the oil-absorbing pad, ensuring its effective absorption and improving the efficiency and separation rate of the centrifugal separation while reducing waste.

[0004] Regarding the aforementioned technologies, the inventors discovered the following drawbacks: In actual use, after the grease is separated, it differs from water. After separation, it is thrown onto the inner wall of the centrifuge, resulting in an oil film on the inner wall. When the grease separated from the centrifuge flows down the inner wall of the centrifuge through the through-hole, the oil film increases the flow resistance of the newly flowing grease. Originally, the grease could flow smoothly to the collection point by gravity and other factors, but with the presence of the oil film, the grease flow may be slow, stagnant, or even locally accumulated. This is not conducive to the rapid and efficient collection of grease, affecting the efficiency of grease collection during processing. Therefore, it is necessary to design a centrifugal separation device for producing powdered grease that is highly practical and can accelerate oil discharge. Utility Model Content

[0023] 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.

[0024] Please see Figure 1-4 The present invention provides a technical solution: a centrifugal separation device for producing powdered oil, comprising an outer frame 1, a drive rod 2 rotatably fitted to the lower side of the inner wall of the outer frame 1, a centrifugal barrel 3 fixedly connected to the upper end of the drive rod 2, the centrifugal barrel 3 being a stainless steel barrel with several oil discharge holes, a drive motor 4 cooperating with the drive rod 2 fixedly connected to the lower side of the outer frame 1, and a limiting block 5 rotatably fitted to the centrifugal barrel 3 fixedly connected to the inner wall of the outer frame 1.

[0025] The lower side of the limiting block 5 is rotatably fitted with an internal gear ring 6. A deceleration assembly 7 is provided between the internal gear ring 6 and the centrifugal tank 3. A heating assembly 8 is provided inside the outer frame 1. Two oil outlets 9 are opened on the lower side of the outer frame 1. A support assembly 10 is provided on the lower side of the outer frame 1. A scraper 11 that contacts the inner wall of the outer frame 1 is fixedly connected to the lower side of the internal gear ring 6. The scraper 11 is set in an inclined shape.

[0026] Please see Figure 3 The speed reduction assembly 7 includes a speed reduction rod 701 rotatably fitted to the lower side of the limiting block 5, an external gear ring 702 fixedly connected to the centrifuge drum 3, a large gear 703 fixedly connected to the speed reduction rod 701 and meshing with the external gear ring 702, and a small gear 704 fixedly connected to the speed reduction rod 701 and meshing with the internal gear ring 6. The entire speed reduction assembly 7 plays a role in regulating the rotational speed. From the high-speed rotating centrifuge drum 3 to the relatively low-speed rotating internal gear ring 6, the different tooth ratios of the large gear 703 with the external gear ring 702 and the small gear 704 with the internal gear ring 6 can achieve reasonable control of the final rotational speed of the internal gear ring 6. This avoids the internal gear ring 6 and its connected scraper 11 and other components rotating too fast.

[0027] Please see Figure 3 The heating component 8 includes a heating cavity 801 formed in the inner wall of the outer frame 1 and a heating tube 802 fixedly connected to the inner wall of the heating cavity 801. The heating tube 802 can be a common heating wire tube on the market. Heating through the heating tube 802 can heat the inside of the heating cavity 801 and then conduct it to the inside of the outer frame 1, which can play a role in preventing the raw materials and residual grease on the inner wall of the outer frame 1 from sticking.

[0028] Please see Figure 2 The support assembly 10 includes multiple support rods 101 fixedly connected to the lower side of the outer frame 1, a base 102 fixedly connected to the lower end of the multiple support rods 101, and a collection frame 103 disposed on the upper side of the base 102 and cooperating with the oil outlet 9. With the support of the base 102 and the support rods 101, the height of the outer frame 1 can be raised. The collection frame 103 is located on the lower side of the corresponding oil outlet 9, which facilitates the unified collection of separated grease.

[0029] Please see Figure 2The top cover 12 is provided on the upper side of the outer frame 1. Fasteners 13 that cooperate with the outer frame 1 are fixedly connected to both sides of the top cover 12. The fasteners 13 can be composed of multiple threaded blocks, which are fixed to the top cover 12 and the outer frame 1 respectively. The two are fixed by inserting the fasteners 13 through them and then tightening the bolts by hand.

[0030] Please see Figure 2 A connecting rod 14 is fixedly connected to the lower side of the top cover 12, and a limiting ring 15 located inside the centrifuge tank 3 is fixedly connected to the lower side of the connecting rod 14. After the top cover 12 is installed, the limiting ring 15 is pushed into the inner wall of the centrifuge tank 3 by the connecting rod 14 to restrict the product inside the centrifuge tank 3 and prevent it from flying out of the centrifuge tank 3 due to the centrifugal principle.

[0031] Please see Figure 2 Two guide blocks 16 are fixedly connected to the upper side of the base 102. Each of the two collection boxes 103 is provided with a limiting plate 17 that slides with the guide block 16. When the collection box 103 is placed, the collection box 103 can be limited by putting the limiting plate 17 on the outside of the guide block 16.

[0032] The implementation principle of this application is as follows: When using this device, first open the top cover 12, put the raw material to be separated into the centrifuge barrel 3, then close the top cover 12, and start the drive motor 4 to drive the centrifuge barrel 3 to rotate. As the centrifuge barrel 3 rotates at high speed, the grease on the raw material is thrown out from the gap in the centrifuge barrel 3. During the rotation of the centrifuge barrel 3, the limiting block 5 is on the outside of the centrifuge barrel 3 to limit the upper side of the centrifuge barrel 3, and the grease thrown out will be thrown onto the inner wall of the outer frame 1.

[0033] During the rotation of the centrifuge barrel 3, the external gear ring 702 fixed on the centrifuge barrel 3 also rotates together. The external gear ring 702 meshes with the large gear 703 on the reduction rod 701, thereby driving the reduction rod 701 to rotate. The small gear 704 on the reduction rod 701 meshes with the internal gear ring 6, thereby driving the scraper 11 on the side of the internal gear ring 6 to rotate the inner wall of the outer frame 1. During the rotation of the scraper 11, it generates a downward pushing force on the scraped grease, thereby accelerating the flow of grease and improving the overall efficiency of grease separation and collection.

[0034] During use, the heating tube 802 in the heating chamber 801 can be heated to raise the temperature inside the outer frame 1, which can effectively reduce the viscosity of the grease, making it thinner and more fluid. Under the action of centrifugal force, the grease can be separated from the raw material more quickly and smoothly, and can flow down efficiently along the inner wall of the outer frame 1, accelerating the entire separation and collection process and further improving production efficiency.
