Description

Technical Field

[0001] This utility model relates to the field of fish oil filter press technology, and in particular to a fish oil filter press that facilitates the observation of fish oil. Background Technology

[0002] Fish oil filter presses are key equipment in the fish oil production and processing process. They are mainly used to filter and purify the initially extracted fish oil, removing impurities, protein residues, moisture and other harmful substances to improve the purity, quality and storage stability of the fish oil. They are widely used in aquatic product processing, health product production and other fields.

[0003] Existing fish oil filter presses have technical defects. Traditional filter presses mostly use a single filtration structure, which is difficult to fully intercept fine impurities in fish oil. As a result, a small amount of particulate matter may still remain in the filtered fish oil, affecting product purity. The oil collection process lacks intuitive observation methods, and operators cannot monitor the amount of fish oil collected, its clarity, and the filtration status in real time. It is difficult to detect problems such as filter blockage and fish oil contamination in a timely manner, which can easily lead to product waste or quality risks. The filtration structure is mostly a fixed design, and after long-term use, impurities can easily adhere to the surface of the filter element and form blockages. Moreover, the disassembly and cleaning process is cumbersome, which affects the operating efficiency of the equipment. The sealing performance of some conveying pipes to the main body of the equipment is poor. Fish oil leakage is prone to occur under long-term pressure or during transportation, which not only wastes raw materials but may also cause safety hazards. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned technology and provide a fish oil filter press that facilitates the observation of fish oil.

[0005] Therefore, this utility model provides a fish oil filter press for easy observation of fish oil, including a filter press body. An inclined conveying pipe is fixedly connected to the right side of the filter press body. A filter box is fixedly connected to the right end of the inclined conveying pipe. A horizontal conveying pipe is fixedly connected to the right side of the filter box. An oil collection tank is fixedly connected to the right end of the horizontal conveying pipe. Fixed frames are fixedly connected to the front and rear inner walls of the filter box, respectively. A fixed rod is fixedly connected to the inner side of the fixed frame. A spring and a sliding block are sleeved on the outer side of the fixed rod. A sliding block is fixedly connected to the left end of the spring. A support rod is fixedly connected to the middle of the two sliding blocks. A filter plate is rotatably connected to the outer side of the support rod.

[0006] Preferably, a filter disc is provided at the bottom of the oil collection tank, a vertical rod is fixedly connected to the top surface of the filter disc, and a float is fixedly connected to the top of the vertical rod.

[0007] Preferably, the surface of the filter plate is uniformly distributed with fine filter holes, the filter plate is made of highly corrosion-resistant stainless steel, and the floating plate is made of foam board.

[0008] Preferably, the inclined conveying pipe is connected to the filter press body and the filter box using flange connections.

[0009] Preferably, the oil collecting tank is made of transparent glass, the outside of the oil collecting tank is marked with scale markings, and the bottom of the filter press body is provided with support feet.

[0010] Preferably, the surface of the filter disc is provided with multiple layers of filter membrane, and the outer side of the filter disc is in contact with the inner wall of the oil collection tank.

[0011] Preferably, the right end of the spring is fixedly connected to the inner wall of the fixing frame, the sliding block and the fixing rod are in a sliding sleeve fit, and the inner wall of the sliding block is coated with a wear-resistant coating.

[0012] This utility model provides a fish oil filter press that facilitates observation of fish oil, and has the following beneficial effects:

[0013] (1) The filter plate installed in the filter box by means of a fixed frame, a fixed rod, a spring, a sliding block and a support rod can achieve elastic shaking and slight rotation under the pressure of fish oil delivery. On the one hand, it intercepts most of the impurities through the fine filter holes on the surface. On the other hand, the elastic shaking can prevent impurities from quickly adhering and clogging, thus improving the continuity of filtration. The multi-layer filter mesh filter disc at the bottom of the oil collection tank can perform secondary deep purification on the fish oil after preliminary filtration. The dual filtration structure effectively removes fine impurities and greatly improves the purity of fish oil. At the same time, the filter plate is made of stainless steel with strong corrosion resistance, which is suitable for the chemical properties of fish oil and extends its service life. The filter disc and the inner wall of the oil collection tank are reserved to ensure smooth flow of fish oil and avoid secondary clogging.

[0014] (2) This utility model allows operators to intuitively read the amount of fish oil collected by setting scale marks on the outside of the oil collection tank, and accurately control the production progress. The floating plate is made of lightweight buoyancy material and rises and falls synchronously with the oil level in the oil collection tank. Combined with the connection structure between the vertical rod and the filter plate, it can not only help judge the oil level by the position of the floating plate, but also indirectly reflect the clarity of the fish oil. If the floating plate rises abnormally or tilts, it may indicate that the filter is blocked or there are too many impurities, thus realizing real-time monitoring of the fish oil collection status.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0021] Depend on Figures 1-4 As shown, this utility model provides a fish oil filter press for easy observation of fish oil, including a filter press body 1. An inclined conveying pipe 2 is fixedly connected to the right side of the filter press body 1. A filter box 3 is fixedly connected to the right end of the inclined conveying pipe 2. A horizontal conveying pipe 4 is fixedly connected to the right side of the filter box 3. An oil collection tank 5 is fixedly connected to the right end of the horizontal conveying pipe 4. Fixing frames 6 are fixedly connected to the front and rear inner walls of the filter box 3, respectively. A fixing rod 7 is fixedly connected to the inner side of the fixing frame 6. A spring 8 and a sliding block 9 are sleeved on the outer side of the fixing rod 7. A sliding block 9 is fixedly connected to the left end of the spring 8. A support rod 10 is fixedly connected to the middle of the two sliding blocks 9. A filter plate 11 is rotatably connected to the outer side of the support rod 10.

[0022] After the filter press body 1 performs pressure pretreatment on the initially extracted fish oil, the fish oil enters the filter box 3 through the inclined conveying pipe 2 under pressure. When the fish oil impacts the filter plate 11, it pushes the filter plate 11 to drive the sliding block 9 to slide left and right along the fixed rod 7 through the support rod 10. At the same time, the spring 8 is stretched and deformed, and the filter plate 11 can rotate slightly around the support rod 10, forming an elastic shaking state. This dynamic filtration method can not only intercept most impurities through the filter plate 11, but also prevent impurities from quickly adhering to the surface of the filter plate 11 and causing blockage through shaking, ensuring that the filtration process continues to be efficient. The fish oil after preliminary filtration is transported to the oil collection tank 5 through the horizontal conveying pipe 4.

[0023] Furthermore, a filter plate 12 is installed at the bottom of the oil collection tank 5, and a vertical rod 13 is fixedly connected to the top surface of the filter plate 12. A float plate 14 is fixedly connected to the top of the vertical rod 13. After the fish oil is initially filtered, it first flows through the filter plate 12 at the bottom for secondary deep filtration to further remove fine impurities. The float plate 14 rises synchronously under the action of buoyancy and is connected to the filter plate 12 through the vertical rod 13 to ensure that the float plate 14 always rises and falls smoothly in the vertical direction. The operator can intuitively judge the oil level and fish oil collection progress in the oil collection tank 5 by the position change of the float plate 14.

[0024] Furthermore, the surface of the filter plate 11 is evenly distributed with fine filter holes. The filter plate 11 is made of highly corrosion-resistant stainless steel, and the float 14 is made of foam board. The fine filter holes on the surface of the filter plate 11 can accurately intercept small impurities in the fish oil, improving the purification effect of the initial filtration. The float 14 can sensitively respond to subtle changes in the oil level in the oil collection tank 5.

[0025] Furthermore, the inclined conveying pipe 2 is connected to the filter press body 1 and the filter box 3 using flanges; the flanges are tightened with bolts to form a tightly fitted and sealed structure between the inclined conveying pipe 2, the filter press body 1, and the filter box 3.

[0026] Furthermore, the oil collection tank 5 is made of transparent glass, and scale markings are provided on the outer side of the oil collection tank 5. Support feet are provided at the bottom of the filter press body 1. The scale markings on the outside of the oil collection tank 5 provide operators with an intuitive quantitative reference, allowing them to directly read the amount of fish oil collected and accurately control the production progress. The support feet at the bottom of the filter press body 1 can keep the equipment in a stable position and prevent displacement due to vibration during operation.

[0027] Furthermore, the surface of the filter disc 12 is provided with multiple layers of filter membranes, and the outer side of the filter disc 12 is in contact with the inner wall of the oil collection tank 5. The multiple layers of filter membranes on the surface of the filter disc 12 form a gradient filtration structure, which can intercept the fine impurities, protein residues and other harmful substances remaining in the fish oil layer by layer. The gap reserved between the filter disc 12 and the inner wall of the oil collection tank 5 provides a smooth flow channel for the fish oil, avoiding the obstruction of fish oil flow due to the filter membrane intercepting impurities.

[0028] Furthermore, the right end of the spring 8 is fixedly connected to the inner wall of the fixed frame 6, and the sliding block 9 and the fixed rod 7 are in a sliding sleeve fit. The inner wall of the sliding block 9 is coated with a wear-resistant coating. The right end of the spring 8 is fixed to the inner wall of the fixed frame 6, and the left end is connected to the sliding block 9. When the filter plate 11 is impacted by fish oil, the spring 8 provides elastic support for the sliding block 9 through extension and contraction, so that the sliding block 9 can slide flexibly along the fixed rod 7, thereby driving the filter plate 11 to achieve elastic shaking and slight rotation. The sliding sleeve fit between the sliding block 9 and the fixed rod 7 ensures the smoothness of sliding.

[0029] Working principle: When the fish oil filter press is working, the pre-extracted fish oil is first pressurized by the filter press body 1 to remove some large molecular impurities and water. The fish oil that has completed the pre-filtration is transported to the filter box 3 through the inclined conveying pipe 2 under pressure. When the fish oil enters the filter box 3, it impacts the surface of the filter plate 11. The filter plate 11 is connected to the sliding block 9 through the support rod 10. The sliding block 9 is sleeved on the fixed rod 7 and fixed to the spring 8. Under the impact of the fish oil, the sliding block 9 slides left and right along the fixed rod 7, and the spring 8 extends and deforms accordingly. At the same time, the filter plate 11 can rotate slightly around the support rod 10 to achieve an elastic shaking state. The fine filter holes on the surface of the filter plate 11 pre-intercept impurities in the fish oil, and the elastic shaking can prevent impurities from quickly accumulating and clogging the surface of the filter holes, ensuring continuous filtration. The fish oil after pre-filtration is transported to the oil collection tank 5 through the horizontal conveying pipe 4.

[0030] Fish oil entering the oil collection tank 5 first passes through the bottom filter plate 12. The multi-layer filter membrane on the surface of the filter plate 12 performs secondary deep filtration on the fish oil, further removing fine impurities. The purified fish oil is stored in the oil collection tank 5. As fish oil is continuously added, the oil level in the oil collection tank 5 gradually rises. The float plate 14 rises vertically under the action of buoyancy. The operator can read the amount of fish oil collected through the scale markings on the outside of the oil collection tank 5, and at the same time observe the rising state of the float plate 14 to judge the clarity of the fish oil and whether the filtration is normal. If the float plate 14 rises slowly, it may indicate that the filter plate 11 or filter plate 12 is blocked, and it needs to be cleaned in time. If the float plate 14 is tilted, there may be problems such as too many impurities, so it is convenient to stop the machine for inspection in time.
