Description

Technical Field

[0001] This utility model relates to the field of edible oil processing technology, and in particular to a multi-stage filtration device for edible oil processing. Background Technology

[0002] Edible oil is an indispensable food ingredient in daily life, and its quality and safety are directly related to consumers' health. The processing of edible oil involves multiple stages, including raw material pretreatment, pressing or leaching, and filtration and purification. Among these, filtration is one of the key processes that determines the quality of the oil.

[0003] Filtration effectively removes solid impurities, colloids, and suspended matter from edible oils, improving their transparency, stability, and taste. With consumers' increasing demands for food safety and quality, and the food industry's stringent requirements for standardized and regulated production processes, edible oil processing companies urgently need efficient and reliable filtration technologies and equipment to meet market demands and enhance product competitiveness. Multi-stage filtration devices, as a type of equipment capable of achieving fine filtration, can progressively purify edible oils by setting multiple layers of filter media with varying precision, demonstrating enormous application potential in the edible oil processing field.

[0004] Existing edible oil filtration devices employ a single-layer filtration structure. This type of device introduces the edible oil to be filtered into a filtration chamber containing a single filter medium. By utilizing the pore size of the filter medium to intercept impurities in the oil, it separates the oil from the edible oil, thereby achieving the effect of preliminary purification of the edible oil. However, since single-layer filtration relies on only a single filter medium for a single filtration operation, its filtration accuracy and efficiency are significantly limited.

[0005] In actual production, the pore size of a single-layer filter medium is difficult to meet the interception requirements of impurities of different particle sizes at the same time. For impurities and colloidal substances with smaller particle sizes, single-layer filtration often cannot effectively remove them, resulting in the edible oil still having turbidity and impurity residue after filtration. At the same time, after long-term use, the filtration speed of a single-layer filter medium will be reduced due to impurity blockage, increasing production time costs, and frequent replacement of filter media will lead to increased consumable costs. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0033] Reference Figure 2 , Figure 3 and Figure 4 This utility model provides an embodiment of a multi-stage filtration device for edible oil processing, comprising a processing box 1 and a shock-absorbing pad 20. The processing box 1 is fixedly connected to the top of the shock-absorbing pad 20. A crushing mechanism 2 is provided on the top of the processing box 1. A hydraulic column 3 is fixedly connected to the left side inside the processing box 1. A movable push plate 4 is fixedly connected to the right end of the hydraulic column 3. A fixed storage box 5 is fixedly connected to the right side inside the processing box 1. The right end of the movable push plate 4 passes through the interior of the fixed storage box 5. Multiple oil outlet holes 6 are opened on the right side of the fixed storage box 5. A cross-sectional area is fixedly connected to the bottom right end of the processing box 1. The filter box 7 has multiple slots 8 evenly spaced inside, and filter plates 9 are slidably connected inside each slot 8. Filter holes 10 are opened on the top of each filter plate 9. The size of the filter holes 10 decreases from high to low. An oil storage assembly is set on the bottom left side of the processing box 1. The oil storage assembly includes an oil tank 11. The oil tank 11 is fixedly connected to the top left side of the shock-absorbing pad 20. A water pump 12 is fixedly connected to the top center of the shock-absorbing pad 20. The input end of the water pump 12 is connected to the bottom end of the filter box 7, and the output end of the water pump 12 is connected to the top right side of the oil tank 11.

[0034] Specifically, the shock-absorbing pad 20 serves as a basic component, supporting the processing box 1 and the oil storage tank 11. It also absorbs vibrations generated during operation, reducing the impact of vibrations on the equipment. The crushing mechanism 2 at the top of the processing box 1 is used to crush the oil, breaking large pieces into smaller particles. The hydraulic column 3, fixedly connected to the left side inside the processing box 1, is the core power component for pushing the oil to be squeezed out. After the hydraulic column 3 is activated, the movable push plate 4, fixedly connected to its right end, moves to the right. The right end of the movable push plate 4 penetrates the interior of the fixed storage box 5. As the movable push plate 4 advances, the oil in the fixed storage box 5 is squeezed. Multiple oil outlet holes 6 on the right side of the fixed storage box 5 allow the extracted edible oil to flow out through the oil outlet holes 6 when the oil is compressed. The edible oil flowing out from the oil outlet holes 6 of the fixed storage box 5 drips to the bottom of the processing box 1 and then flows into the filter box 7 fixedly connected to the bottom right end. Multiple slots 8 equidistantly opened inside the filter box 7 provide installation positions for the filter plates 9. The multiple filter plates 9 slide... The filter plate 9 is connected to the slot 8, and the filter holes 10 on the top of the filter plate 9 are arranged from high to low, with the size decreasing sequentially. The edible oil flows from top to bottom in the filter box 7. It first passes through the upper filter plate 9 with larger filter holes 10, which filters out larger impurity particles. As the oil flows downward, it passes through the lower filter plates 9 with gradually smaller filter holes 10, achieving multi-stage filtration of impurities of different sizes in the edible oil. This ensures that the filtered edible oil reaches a high level of purity. The edible oil after multi-stage filtration is collected at the bottom of the filter box 7. The water pump 12 is fixedly connected to the center of the top of the shock-absorbing pad 20. Its input end is connected to the bottom of the filter box 7. When the water pump 12 is started, it draws the edible oil from the bottom of the filter box 7 and transports it to the oil storage tank 11. The oil storage tank 11 is fixedly connected to the left side of the top of the shock-absorbing pad 20 and is used to store the filtered edible oil. This realizes the whole process of edible oil processing from raw material processing to filtration and storage, effectively improving the quality and production efficiency of edible oil. Compared with traditional single-layer filtration, it greatly increases the filtration effect.

[0035] Reference Figure 1 and Figure 5 The crushing mechanism 2 includes a crushing box 201, which is fixedly connected to the top right side of the processing box 1. A mounting plate 202 is fixedly connected to the top rear side of the processing box 1. A drive motor 203 is fixedly connected to the top of the mounting plate 202. Two crushing wheels 204 are rotatably connected inside the crushing box 201. The output end of the drive motor 203 is fixedly connected to the rear end of the right crushing wheel 204. Gears 205 are fixedly connected to the rear outer side of both crushing wheels 204. Inclined plates 206 are fixedly connected to the left and right sides of the top inner end of the crushing box 201.

[0036] Specifically, the crushing box 201 is fixedly connected to the top right side of the processing box 1, providing an installation carrier for the internal crushing components. The mounting plate 202 fixedly connected to the rear top of the processing box 1 supports and fixes the drive motor 203, ensuring the stable installation of the drive motor 203 and providing power for the crushing operation. After the drive motor 203 starts, its output end drives the right-end crushing wheel 204 to rotate. The two crushing wheels 204 are rotatably connected inside the crushing box 201, and the gears 205 fixedly connected to their rear sides mesh with each other. When the right-end crushing wheel 204 rotates under the drive of the drive motor 203, the left-end crushing wheel 204 rotates synchronously in the opposite direction through the transmission action of the gears 205. The surfaces of the two crushing wheels 204 are provided with raised tooth-like structures, forming a crushing working surface that rotates in opposite directions. After the oil is put into the crushing box 201 from the top, it is guided by the inclined plates 206 fixedly connected to the left and right sides of the top of the crushing box 201. The tilt angle causes the input oil to slide towards the crushing wheel 204, precisely falling into the crushing area between the two crushing wheels 204. As the two crushing wheels 204 continue to rotate in opposite directions, the oil is squeezed and sheared by the surface structure of the crushing wheels 204, and large pieces of oil are crushed into smaller particles. During the crushing process, the gear 205 ensures that the two crushing wheels 204 have the same rotation speed and opposite direction, maintaining stable crushing force and efficiency. The crushed oil particles fall into the processing box 1 from the bottom opening of the crushing box 201 under their own gravity, and enter the subsequent oil extrusion process. The inclined plate 206 not only guides the oil into the crushing area, but also prevents the oil from accumulating on the top of the crushing box 201, ensuring continuous crushing operation and achieving efficient crushing of the oil, crushing it into particles that meet the requirements for oil extrusion, laying the foundation for the subsequent edible oil processing process, and ensuring the overall processing efficiency and product quality of the multi-stage filtration device.

[0037] Reference Figure 1 , Figure 2 and Figure 4 An oil outlet pipe 13 is connected to the bottom left side of the oil storage tank 11, and a solenoid valve 14 is fixedly installed in the middle of the oil outlet pipe 13; handles 15 are fixedly connected to the front of multiple filter plates 9, and the outside of multiple handles 15 is designed with anti-slip; sealing bolts 16 pass through the left and right ends of the front of multiple filter plates 9, and the ends of multiple sealing bolts 16 are threaded to the left and right ends of the front of the filter box 7; a controller 17 is fixedly connected to the top left side of the processing box 1, and the controller 17 is electrically connected to the hydraulic column 3, water pump 12, solenoid valve 14 and drive motor 203; a slag removal door 18 is rotatably connected to the front of the processing box 1, and two sliding bolts 19 are fixedly connected to the right end of the front of the slag removal door 18;

[0038] Specifically, the oil outlet pipe 13 connected to the bottom left side of the oil storage tank 11 is the channel for outputting filtered edible oil. A solenoid valve 14 is installed in the middle of the oil outlet pipe 13, controlling the oil flow by energizing and de-energizing. When edible oil needs to be output, the solenoid valve 14 is energized and opened, allowing the edible oil to flow out through the oil outlet pipe 13 under pressure. When oil output is not needed or for equipment maintenance, the solenoid valve 14 is de-energized and closed, blocking the flow of edible oil and achieving precise control of the oil output process. The handle 15 fixed to the front of the filter plate 9 has an anti-slip design for easy gripping by the operator. When cleaning or replacing the filter plate 9, the operator holds the handle 15 and unscrews the sealing bolts 16 that pass through the left and right ends of the front side of the filter plate 9. The ends of the sealing bolts 16 are threaded to the left and right ends of the front side of the filter box 7. After unscrewing, the filter plate 9 can be pulled out of the slot 8 of the filter box 7. After cleaning or replacement... Reinsert the filter plate 9 into the slot 8 and tighten the sealing bolt 16 to ensure a sealed connection between the filter plate 9 and the filter box 7, preventing edible oil leakage. The controller 17, fixed on the top left side of the processing box 1, is electrically connected to the hydraulic column 3, water pump 12, solenoid valve 14, and drive motor 203 via wires. The operator sets parameters on the controller 17 to achieve centralized control of each key component. The slag removal door 18, which is rotatably connected to the front of the processing box 1, is used to clean the residue inside the processing box 1. When it is necessary to clean the residue, open the two sliding bolts 19 fixed on the right side of the front of the slag removal door 18 to release the locked state of the slag removal door 18, and then rotate the slag removal door 18 to open it, so that the oil residue remaining inside the processing box 1 can be cleaned. After cleaning, close the slag removal door 18 and reinsert the sliding bolts 19 to lock it, ensuring the sealing and safety of the processing box 1.

[0039] Working principle: The crushing mechanism 2 at the top of the processing box 1 is used to crush the oil, breaking large pieces of oil into smaller particles. The hydraulic column 3, fixedly connected to the left side inside the processing box 1, is the core power component that pushes the oil to be squeezed out. After the hydraulic column 3 is started, the movable push plate 4, fixedly connected to its right end, moves to the right. The right end of the movable push plate 4 penetrates the inside of the fixed storage box 5. As the movable push plate 4 moves forward, the oil in the fixed storage box 5 is squeezed. Multiple oil outlet holes 6 are opened on the right side of the fixed storage box 5. When the oil is compressed, the extracted edible oil flows out through the oil outlet holes 6. The edible oil flowing out from the oil outlet holes 6 of the fixed storage box 5 drips to the bottom of the processing box 1, and then flows into the filter box 7 fixedly connected to the bottom right end. Multiple slots 8 are equally spaced inside the filter box 7 to provide installation positions for the filter plates 9. The filter plate 9 is slidably connected in the slot 8, and the filter holes 10 on the top of the filter plate 9 are arranged from high to low, with the size decreasing sequentially. The edible oil flows from top to bottom in the filter box 7. It first passes through the upper filter plate 9 with larger filter holes 10, which filters out larger impurity particles. As the oil flows downward, it passes through the lower filter plates 9 with gradually smaller filter holes 10, achieving multi-stage filtration of impurities of different sizes in the edible oil. This ensures that the filtered edible oil reaches a high degree of purity. The edible oil after multi-stage filtration is collected at the bottom of the filter box 7. The water pump 12 is fixedly connected to the center of the top of the shock-absorbing pad 20. Its input end is connected to the bottom of the filter box 7. The water pump 12 is started to draw the edible oil from the bottom of the filter box 7 and transport it to the oil storage tank 11. The oil storage tank 11 is fixedly connected to the left side of the top of the shock-absorbing pad 20 and is used to store the filtered edible oil.

[0040] Furthermore, the crushing box 201 provides an installation carrier for the internal crushing components. The mounting plate 202, fixedly connected to the top rear side of the processing box 1, supports and fixes the drive motor 203, ensuring the stable installation of the drive motor 203 and providing power for the crushing operation. After the drive motor 203 starts, its output end drives the right-end crushing wheel 204 to rotate. The two crushing wheels 204 are rotatably connected inside the crushing box 201, and the gears 205 fixedly connected to their external rear sides mesh with each other. When the right-end crushing wheel 204 rotates under the drive of the drive motor 203, the left-end crushing wheel 204 rotates synchronously in the opposite direction through the transmission action of the gears 205. The surfaces of the two crushing wheels 204 are provided with raised tooth-like structures, forming a crushing working surface that rotates in opposite directions. After the oil is put into the crushing box 201 from the top, it is subjected to the crushing action of the crushing box 201. The inclined plates 206, fixedly connected to the left and right sides of the top of the inner part, guide the oil material. The inclination angle of the inclined plates 206 causes the input oil material to slide towards the crushing wheel 204 and fall precisely into the crushing area between the two crushing wheels 204. As the two crushing wheels 204 continue to rotate in opposite directions, the oil material is squeezed and sheared by the structure on the surface of the crushing wheel 204, and large pieces of oil material are crushed into smaller particles. During the crushing process, the gear 205 ensures that the speed of the two crushing wheels 204 is matched and the direction of rotation is opposite, maintaining stable crushing force and efficiency. The crushed oil particles fall into the processing box 1 from the bottom opening of the crushing box 201 under their own gravity, and enter the subsequent oil extrusion process. The inclined plates 206 not only guide the oil material into the crushing area, but also prevent the oil material from accumulating on the top of the crushing box 201, ensuring that the crushing operation is continuous.
