Description

Technical Field

[0001] This application relates to the field of rice bran oil processing technology, and more specifically, to a receiving funnel for extracting rice bran oil. Background Technology

[0002] Rice bran oil is an oil extracted from rice bran obtained when brown rice is processed into white rice. Rice bran oil extraction is a process to obtain raw crude rice bran oil, which involves dissolving the oil in rice bran with No. 6 solvent oil (the main component of which is n-hexane) to obtain a mixed oil.

[0003] In existing technologies, due to the small size of the rice bran raw material used for processing, the resulting mixed oil is prone to contain a large number of rice bran particles. The resulting mixed oil typically requires filtration before further refining. However, the pipelines transporting the mixed oil usually have bends, where rice bran impurities tend to accumulate, reducing the flow rate. The transport pipelines must be cleaned periodically, and the rice bran oil extraction process must be paused during cleaning, significantly reducing production efficiency.

[0004] Therefore, it is necessary for the inventors to design a new receiving funnel for rice bran oil extraction to overcome the above problems. Summary of the Invention

[0005] The main objective of this application is to provide a receiving funnel for rice bran oil extraction, in order to solve the problem of low production efficiency caused by the high frequency of cleaning of rice bran oil mixed oil transportation pipelines in related technologies.

[0006] To achieve the above objectives, this application provides a receiving funnel for rice bran oil extraction, comprising a conveyor belt for conveying rice bran material, a plurality of square funnels fixedly arranged below the conveyor belt along the conveyor belt direction, the width of the square funnels being greater than the width of the conveyor belt, a first filter element fixedly arranged on each square funnel, a discharge port fixedly arranged at the bottom of the square funnel, and a second filter element fixedly arranged in the discharge port.

[0007] Optionally, the first filter element includes two mounting plates, which are symmetrically mounted on the two side plates of the square funnel. A filter screen is fixedly disposed between the bottoms of the two mounting plates, and the edge of the filter screen abuts against the inclined plate of the square funnel.

[0008] Optionally, the mounting plate extends into the interior of the funnel, and the distance between the filter screen and the top surface of the funnel is greater than 60mm and less than 150mm.

[0009] Optionally, the distance between the filter screen and the top surface of the funnel is 100mm.

[0010] Optionally, a number of connecting rods are also fixedly provided between the two mounting plates.

[0011] Optionally, the distance between the top of the square funnel and the conveyor belt is greater than the distance between the filter screen and the top of the square funnel.

[0012] Optionally, the second filter element is a filter cartridge, with a limiting ring fixedly provided at the top of the filter cartridge and a limiting groove adapted to the limiting ring fixedly provided at the bottom of the square funnel.

[0013] Optionally, the distance between the bottom of the conveyor belt and the top of the funnel is less than 200 mm.

[0014] Optionally, the filter screen and the mounting plate are detachably connected.

[0015] The present invention provides a receiving funnel for rice bran oil extraction, which has the following advantages compared with the prior art:

[0016] By setting a first filter element on a square funnel to perform preliminary filtration of the falling mixed oil, the first filter element can be quickly replaced when its filtration effect decreases. During this period, rice bran particles in the falling mixed oil can be caught by a second filter element, which greatly reduces the occurrence of rice bran particles entering the conveying pipeline.

[0028] like Figures 1 to 3As shown, a receiving funnel for rice bran oil extraction includes a conveyor belt 1 for conveying rice bran material. Multiple square funnels 2 are fixedly arranged below the conveyor belt 1 along its direction. The width of each square funnel 2 is greater than the width of the conveyor belt 1. A first filter element is fixedly arranged on each square funnel 2, and a discharge port 3 is fixedly arranged at the bottom of each square funnel 2. A second filter element is fixedly arranged in the discharge port 3. Specifically, the rice bran material is conveyed on the conveyor belt 1, and solvent is sprayed onto the rice bran material. The conveyor belt 1 is perforated. After the solvent dissolves the oil in the rice bran material, the mixed oil flows down from the conveyor belt 1 and falls into the square funnels 2 below. The mixed oil first passes through the first filter element to filter out rice bran impurities before entering the square funnel 2, and then passes through the second filter element before entering a transport pipe connected to the discharge port 3. When the filtration effect of the first or second filter element decreases, it can be quickly replaced without interrupting the extraction process. The reason for setting up multiple individual square funnels 2 is that the first filter element and the second filter element in different positions need to be replaced at different frequencies. This setting allows them to be replaced individually.

[0029] The first filter element of the rice bran oil extraction receiving funnel includes two hanging plates 4, which are symmetrically hung on the two side plates of the square funnel 2. A filter screen 5 is fixedly installed between the bottoms of the two hanging plates 4, and the edge of the filter screen 5 abuts against the inclined plate 201 of the square funnel 2. Specifically, when the filter screen is evenly covered with rice bran particles, the flow rate of rice bran oil through the filter screen 5 decreases, and the newly fallen rice bran oil will accumulate and be difficult to leak into the square funnel 2. At this time, the two hanging plates 4 are removed, and then they are taken out together with the filter screen, and a new first filter element is installed to continue the operation.

[0030] The hanging plate 4 of the receiving funnel used for rice bran oil extraction extends into the interior of the funnel, and the distance between the filter screen 5 and the top surface of the funnel is greater than 60mm and less than 150mm. Specifically, since the square funnel 2 has an inclined surface, if the filter screen 5 is too deep, the area of ​​the filter screen will be smaller, and rice bran particles from the mixed oil flowing down from the inclined surface of the square funnel 2 will easily accumulate at the edge of the filter screen, resulting in uneven distribution of rice bran particles. If the depth of the filter screen is too shallow, oil droplets will splash out when the mixed oil falls, and the mixed oil accumulated on the filter screen will easily overflow from the edge of the square funnel 2.

[0031] The distance between the filter screen 5 and the top surface of the funnel used for rice bran oil extraction is 100mm. Specifically, this distance is suitable, balancing the filter screen area and the issue of rice bran particle accumulation.

[0032] Several connecting rods 6 are also fixedly installed between the two hanging plates 4 of the rice bran oil extraction receiving funnel. Specifically, the connecting rods 6 facilitate the removal of the entire first filter element and also provide a rigid connection between the two hanging plates 4.

[0033] The distance between the top of the square funnel 2 used for rice bran oil extraction and the conveyor belt 1 is greater than the distance between the filter screen 5 and the top of the square funnel 2. Specifically, when removing the first filter element, there may be an accumulation of mixed oil above the filter screen. At this time, gently lift the filter screen to allow the accumulated mixed oil to flow into the square funnel 2 through the gap between the filter screen and the inclined surface of the square funnel 2. Care must be taken with the movement in this step to avoid the mixed oil carrying particles from the filter screen into the square funnel 2 through the side gaps. The accumulated mixed oil itself contains very few rice bran particles, which can be filtered by the second filter element below. The first filter element is then removed from the space between the square funnel 2 and the conveyor belt 1.

[0034] The second filter element in the rice bran oil extraction receiving funnel is a filter cylinder 7. A limiting ring 8 is fixedly installed at the top of the filter cylinder 7, and a limiting groove 9 adapted to the limiting ring 8 is fixedly installed at the bottom of the square funnel 2. Specifically, the engagement between the limiting ring 8 and the limiting groove 9 ensures that the filter cylinder 7 is placed stably.

[0035] The distance between the bottom of the conveyor belt 1 and the top of the funnel used for rice bran oil extraction is less than 200mm. Specifically, if this distance is too large, the kinetic energy of the mixed oil falling from above will be greater, impacting the rice bran particles accumulated on the filter screen and causing uneven filtration.

[0036] The filter screen 5 and the hanging plate 4 of the receiving funnel for rice bran oil extraction are detachably connected. Specifically, after the filter screen is used up, it can be replaced with a new one by disassembling it.

[0037] In this embodiment, a first filter element is set on the square funnel 2 to perform preliminary filtration of the falling mixed oil. When the filtration effect of the first filter element decreases, it can be quickly replaced. During this period, the rice bran particles in the falling mixed oil can be caught by the second filter element, which greatly reduces the situation of rice bran particles entering the conveying pipeline.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
