Description

Technical Field

[0001] This utility model relates to the field of edible oil production technology, and more specifically, to a filter press for producing edible oil. Background Technology

[0002] In existing technologies, pressure is the key factor driving liquid through the filter plate. Without sufficient pressure, the oil cannot effectively pass through the tiny pores of the filter plate, which not only leads to a significant decrease in filtration efficiency but may also cause the raw materials to stagnate in the system, increasing the risk of oxidation and deterioration. Secondly, the inability to form a sealed filtration space will lead to leakage and contamination problems during the filtration process. A sealed space not only ensures the integrity of filtration but also prevents the introduction of external impurities and the loss of valuable oil. In addition, if solid impurities in edible oil cannot be effectively separated, they will directly affect the quality and safety of the final product. These impurities may include plant fibers, protein residues, or other insoluble substances. Their presence will affect the clarity and taste of the oil and may even introduce harmful substances. Finally, the inability to control and adjust the filtration pressure means that the equipment loses its flexibility to adapt to the characteristics of different raw materials. Different types of edible oil raw materials, such as soybean oil, peanut oil, or olive oil, require different filtration pressures and times due to differences in their composition and physical properties. Without this adjustment capability, the equipment will not be able to optimize the processing of various raw materials, resulting in unstable product quality and low production efficiency. The inability to apply the necessary pressure to the raw materials means that the entire filtration process loses its power source.

[0003] Furthermore, under high pressure, unstable filter plates may experience slight movement or deformation, altering the gaps and pressure distribution between them, directly impacting filtration uniformity and efficiency. Secondly, manual installation and removal of filter plates is not only time-consuming but also increases the workload for operators. In large-scale production, this inefficient operation significantly prolongs production cycles and increases labor costs. More importantly, manual operation increases the risk of errors; improper filter plate installation can lead to incomplete sealing, leakage, or uneven filtration. In extreme cases, incorrectly installed filter plates may suddenly detach under high pressure, causing product loss and potentially injuring operators. Moreover, rapid replacement and cleaning of filter plates are crucial for maintaining continuous production. Failure to perform these operations quickly will result in frequent, prolonged shutdowns, severely impacting production efficiency. This not only increases production costs but may also affect product quality, especially when processing easily oxidized edible oils. Prolonged shutdowns can also cause residual raw materials in the equipment to deteriorate, further affecting the quality of subsequent batches. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a filter press for producing edible oil, so as to solve the technical problems mentioned in the background art, such as the inability to control and adjust the filtration pressure, and the fact that manual installation and disassembly of filter plates is not only time-consuming, but also increases the labor intensity of operators.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a filter press for producing edible oil, comprising a base frame, on which a filter pressing mechanism is mounted. The filter pressing mechanism includes a support plate, a hydraulic cylinder, a pressure plate, filter plates, support rods, and support blocks.

The pressure plate is mounted on the telescopic end of the hydraulic cylinder. Multiple sets of filter plates are disposed between the pressure plate and the support plate. Support rods are mounted on both sides of the two sets of support plates. Multiple sets of support plates are mounted on both sides of the multiple sets of filter plates by means of a fixing mechanism. The fixing mechanism includes fixing holes, fixing rods, fixing sleeves, fixing blocks, fixing grooves, transmission blocks, and locking sleeves. Fixing holes are disposed on the multiple sets of support blocks. Fixing rods are mounted on both sides of the filter plates. Fixing sleeves are disposed on the outer wall of the fixing rods. Multiple sets of fixing blocks slide on the fixing sleeves. Multiple sets of fixing grooves are distributed on the outer wall of the fixing sleeves. Transmission blocks are mounted on the outer side of the multiple sets of fixing blocks. Locking sleeves slide on the outer side of the fixing sleeves.

[0008] The present invention is further configured such that each of the two sets of support rods is equipped with a sliding strip, and the two sets of sliding strips are slidably connected to the multiple sets of support blocks. This design ensures the stable movement of the support blocks during the filter pressing process, which not only improves the filtration effect but also extends the service life of the equipment and reduces maintenance requirements.

[0009] The present invention is further configured such that the locking sleeve is provided with an inclined groove, and the inclined groove is provided in multiple sets and slidably connected to multiple sets of the transmission blocks. This design realizes the conversion between the vertical movement of the locking sleeve and the horizontal movement of the transmission blocks. This mechanism simplifies the locking process, improves the operating efficiency, and ensures the reliability and consistency of the fixation.

[0010] The present invention is further provided that a compression spring is installed at the top of the inner end of the fixing sleeve. The setting of the compression spring increases the reliability of the fixing mechanism, which improves the safety of the entire system, reduces the risk of the filter plate loosening or falling off, and also compensates for possible mechanical wear.

[0011] The present invention is further configured such that a receiving hopper is installed on the base frame and a receiving cart is provided below the receiving hopper. This design realizes efficient collection and treatment of filtered liquid, which not only improves the efficiency of the entire filtration process, but also reduces the risk of liquid leakage and waste, and is also easy to clean and maintain.

[0012] The present invention is further provided that pulleys are rotatably installed on both sides of the pressure plate. The installation of pulleys significantly reduces the friction when the pressure plate moves, which not only reduces the force required to drive the pressure plate and improves energy efficiency, but also makes the movement of the pressure plate more stable and precise.

[0013] This invention is further configured such that the fixed sleeve is provided with an auxiliary mechanism, the auxiliary mechanism including a control sleeve, an internal gear ring, screws, gears, an annular groove, limiting blocks, and limiting slots. The control sleeve is rotatably mounted on the outside of the fixed sleeve, the internal gear ring is mounted on the bottom end of the control sleeve, multiple sets of screws are provided and rotatably mounted on the fixed sleeve and threadedly connected to the locking sleeve, the gears are mounted on the tops of the multiple sets of screws and mesh with the internal gear rings, the annular groove is located inside the control sleeve, multiple sets of limiting blocks are provided and slidably mounted on the control sleeve with their tops extending into the annular groove, and multiple sets of limiting slots are provided on the outer wall of the fixed sleeve and adapted to the multiple sets of limiting blocks. This design allows the operator to precisely control the position of the locking sleeve by rotating the control sleeve. This mechanism provides highly precise position control, enabling the operator to make fine adjustments according to different filter plate thicknesses and material characteristics, thereby optimizing the filtration effect.

[0014] This invention is further configured such that each of the multiple sets of limiting blocks has a push spring connected to its top end and the inner wall of the annular groove. The push spring ensures that the limiting blocks can automatically return to their initial position. This design increases the reliability and service life of the auxiliary mechanism.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a filter press for producing edible oil, which has the following beneficial effects:

[0017] 1. The filter press mechanism uses a hydraulic cylinder to drive the pressure plate to apply pressure to the filter plate, forming a sealed filtration space to achieve efficient solid-liquid separation. The support plate and support rod provide stable support for the entire structure, while the sliding connection between the slide bar and the support block ensures that the filter plate remains stable under high pressure. The pulleys on both sides of the pressure plate reduce friction and improve the smoothness of the pressure plate movement. This design not only improves filtration efficiency but also ensures the stability and reliability of the filtration process. The collection hopper and collection cart on the base frame facilitate the collection and processing of the filtered liquid, improving the continuity and efficiency of the entire process.

[0018] 2. The fixing mechanism enables quick installation and removal of the filter plates, greatly improving operating efficiency. The cooperation between the fixing rod and the fixing hole provides initial positioning, while the combination of the fixing sleeve, fixing block, and locking sleeve achieves reliable locking. The sliding connection between the inclined groove and the transmission block converts the vertical movement of the locking sleeve into the horizontal movement of the fixing block, realizing a simple and effective locking mechanism. The compression spring inside the fixing sleeve provides additional pressure, further enhancing the fixing effect. This design not only simplifies the filter plate replacement process but also ensures the stability of the filter plates under high pressure, thereby improving the safety and reliability of the entire filtration process.

[0019] 3. The auxiliary mechanism achieves precise control of the locking sleeve position through a combination of control sleeve, internal gear ring, screw, and gear. This design allows operators to adjust the locking degree of the fixing mechanism through simple rotation, improving the accuracy and convenience of operation. The setting of annular groove, limit block, and limit groove enables precise positioning of the control sleeve, while the push spring ensures the automatic return of the limit block. This fine control mechanism not only improves the reliability of the fixing process but also allows for flexible adjustment according to different filter plate thicknesses and material characteristics, thereby optimizing the adaptability and performance of the filter press.

[0031] Please see Figures 1-7 A filter press for producing edible oil includes a base frame 1, on which a filter pressing mechanism is mounted. The filter pressing mechanism includes a support plate 2, a hydraulic cylinder 3, a pressure plate 4, filter plates 5, support rods 6, and support blocks 7. Two sets of support plates 2 are mounted on the base frame 1. The hydraulic cylinder 3 is mounted on one side of the support plate 2 with its telescopic end extending beyond the support plate 2. The pressure plate 4 is mounted on the telescopic end of the hydraulic cylinder 3. Multiple sets of filter plates 5 are arranged between the pressure plate 4 and the support plate 2. Support rods 6 are mounted on both sides of the two sets of support plates 2. The support plate 2 has multiple sets of filter plates 5 connected by fixed supports. The mechanism is installed on both sides of multiple sets of filter plates 5. The fixing mechanism includes fixing holes 8, fixing rods 9, fixing sleeves 10, fixing blocks 11, fixing grooves 12, transmission blocks 13, and locking sleeves 14. Fixing holes 8 are provided on multiple sets of support blocks 7. Fixing rods 9 are installed on both sides of filter plates 5. Fixing sleeves 10 are provided on the outer wall of fixing rods 9. Fixing blocks 11 are provided with multiple sets that slide on fixing sleeves 10. Fixing grooves 12 are provided with multiple sets that are distributed on the outer wall of fixing covers. Transmission blocks 13 are installed on the outside of multiple sets of fixing blocks 11. Locking sleeves 14 slide on the outside of fixing sleeves 10.

[0032] Slide strips 15 are installed on both sets of support rods 6. The two sets of slide strips 15 are slidably connected to multiple sets of support blocks 7. The slide strips 15 installed on the two sets of support rods 6 are slidably connected to multiple sets of support blocks 7, forming a linear guide system. The slide strips 15 provide precise guidance, reduce the shaking and offset of the support blocks 7, thereby improving the stability and accuracy of the entire filter press system.

[0033] The locking sleeve 14 has a slanted groove 16. Multiple sets of slanted grooves 16 are provided and are slidably connected to multiple sets of transmission blocks 13. The multiple sets of slanted grooves 16 on the locking sleeve 14 and the multiple sets of transmission blocks 13 are slidably connected to form a wedge mechanism. When the locking sleeve 14 moves up and down, the slanted grooves 16 guide the transmission blocks 13 to move horizontally, thereby realizing precise control of the fixed block.

[0034] A compression spring 17 is installed at the top of the inner end of the fixing sleeve 10. The compression spring 17 installed at the top of the inner end of the fixing sleeve 10 provides continuous downward pressure, which provides continuous downward pressure to the fixing sleeve 10 to ensure that the fixing mechanism remains stable even under vibration or pressure changes.

[0035] A receiving hopper 18 is installed on the base frame 1, and a receiving cart 19 is installed below the receiving hopper 18. The receiving hopper 18 installed on the base frame 1 and the receiving cart 19 below it form a continuous collection system. The receiving hopper 18 ensures the effective guidance of the filtered liquid, while the receiving cart 19 facilitates the collection and transportation of the liquid.

[0036] Both sides of the pressure plate 4 are rotatably mounted with pulleys 20. The pulleys 20 rotatably mounted on both sides of the pressure plate 4 provide rolling support, which not only reduces the force required to drive the pressure plate 4 and improves energy efficiency, but also makes the movement of the pressure plate 4 more stable and precise.

[0037] In this embodiment, the fixing mechanism is used for quick installation and removal of the filter plate 5. When the filter plate 5 needs to be installed, the fixing rods 9 on both sides of the filter plate 5 are inserted into the fixing holes 8 on the support block 7. The fixing sleeve 10 is fitted onto the outer wall of the fixing rod 9. Multiple sets of fixing blocks 11 slide on the fixing sleeve 10. The locking sleeve 14 slides on the outside of the fixing sleeve 10, and its inclined groove 16 is slidably connected to the transmission block 13. When the locking sleeve 14 moves downward, the inclined groove 16 pushes the transmission block 13, thereby driving the fixing block 11 to move inward and engage in the fixing groove 12 on the fixing rod 9, thus fixing the filter plate 5. The compression spring 17 at the top of the inner end of the fixing sleeve 10 can provide additional pressure to ensure a more stable fixation. When disassembling, simply move the locking sleeve 14 upward, and the fixing block 11 will move inward. Once the filter plate 1 is removed from the fixed groove 12, the filter plate 5 can be taken out. The filter pressing mechanism drives the pressure plate 4 to move through the hydraulic cylinder 3, applying pressure to multiple sets of filter plates 5. Filter chambers are formed between the filter plates 5 to hold the edible oil raw materials to be filtered. When the hydraulic cylinder 3 extends, the pressure plate 4 moves towards the filter plate 5, pressing the filter plate 5 to form a sealed filtration space. The support blocks 7 on both sides of the filter plate 5 are slidably connected to the support rod 6 through the slide strip 15 to ensure that the filter plate 5 remains stable under pressure. The pulleys 20 on both sides of the pressure plate 4 can reduce friction and make the pressure plate 4 move more smoothly. During the filtration process, the liquid flows out through the holes of the filter plate 5, and the solid residue is trapped between the filter plates 5. After the filtration is completed, the hydraulic cylinder 3 retracts and the pressure plate 4 returns to its original position, which is convenient for unloading and cleaning the filter plate 5.

[0038] Please see Figure 7 As one implementation of the auxiliary mechanism: an auxiliary mechanism is provided on the fixed sleeve 10. The auxiliary mechanism includes a control sleeve 21, an internal gear ring 22, a screw 23, a gear 24, an annular groove 25, a limiting block 26, and a limiting groove 27. The control sleeve 21 is rotatably mounted on the outside of the fixed sleeve 10. The internal gear ring 22 is mounted on the bottom end of the control sleeve 21. Multiple sets of screws 23 are provided, all of which are rotatably mounted on the fixed sleeve 10 and threadedly connected to the locking sleeve 14. The gear 24 is mounted on the top of the multiple sets of screws 23 and meshes with the internal gear ring 22. The annular groove 25 is provided on the control sleeve 21. Inside the control sleeve 21, multiple sets of limit blocks 26 are slidably mounted on the control sleeve 21 and their top ends extend into the annular groove 25. Multiple sets of limit grooves 27 are provided on the outer wall of the fixed sleeve 10 and are adapted to the multiple sets of limit blocks 26. The auxiliary mechanism forms a precision transmission system through the control sleeve 21, the internal gear ring 22, the screw 23 and the gear 24, realizing the conversion of rotary motion to linear motion. The meshing of the internal gear ring 22 and the gear 24 transmits the rotary motion to the screw 23. The screw 23 then converts the rotation into linear motion through the threaded connection with the locking sleeve 14.

[0039] Each of the multiple sets of limiting blocks 26 has a push spring 28 connected to the top of the annular groove 25. The push springs 28 connected between the multiple sets of limiting blocks 26 and the annular groove 25 form an automatic reset mechanism. When the control sleeve 21 rotates to the preset position, the limiting block 26 can accurately engage with the limiting groove 27, providing precise positioning.

[0040] More specifically, the auxiliary mechanism is used to precisely control the position of the locking sleeve 14, thereby achieving a more precise fixing operation. The control sleeve 21 is rotatably mounted on the outside of the fixing sleeve 10, and its bottom internal gear ring 22 meshes with the gear 24 at the top of the multiple sets of screws 23. When the control sleeve 21 rotates, the screw 23 is driven to rotate through the transmission of the internal gear ring 22 and the gear 24. The screw 23 is threadedly connected to the locking sleeve 14, so the rotation of the screw 23 is converted into the up and down movement of the locking sleeve 14. The setting of the annular groove 25, the limiting block 26 and the limiting groove 27 realizes the precise positioning of the control sleeve 21. The push spring 28 between the top of the multiple sets of limiting blocks 26 and the inner wall of the annular groove 25 ensures the automatic return of the limiting blocks 26. This design allows the operator to precisely control the position of the locking sleeve 14 by rotating the control sleeve 21, thereby better adjusting the locking degree of the fixing mechanism.

[0041] In summary, during use or operation of the overall equipment: the fixing mechanism is used for quick installation and removal of the filter plate 5. When the filter plate 5 needs to be installed, the fixing rods 9 on both sides of the filter plate 5 are inserted into the fixing holes 8 on the support block 7. The fixing sleeve 10 is fitted onto the outer wall of the fixing rod 9. Multiple sets of fixing blocks 11 slide on the fixing sleeve 10. The locking sleeve 14 slides on the outside of the fixing sleeve 10, and its inclined groove 16 is slidably connected to the transmission block 13. When the locking sleeve 14 moves downward, the inclined groove 16 pushes the transmission block 13, thereby driving the fixing block 11 to move inward and engage in the fixing groove 12 on the fixing rod 9, thus fixing the filter plate 5. The compression spring 17 at the top of the inner end of the fixing sleeve 10 can provide additional pressure to ensure a more stable fixation. When disassembling, simply move the locking sleeve 14 upward. When the fixing block 11 disengages from the fixing groove 12, the filter plate 5 can be removed. The filter pressing mechanism drives the pressure plate 4 to move through the hydraulic cylinder 3, applying pressure to multiple sets of filter plates 5. Filter chambers are formed between the filter plates 5 to hold the edible oil raw materials to be filtered. When the hydraulic cylinder 3 extends, the pressure plate 4 moves towards the filter plate 5, pressing the filter plate 5 to form a sealed filtration space. The support blocks 7 on both sides of the filter plate 5 are slidably connected to the support rod 6 through the slide bar 15 to ensure that the filter plate 5 remains stable under pressure. The pulleys 20 on both sides of the pressure plate 4 can reduce friction and make the pressure plate 4 move more smoothly. During the filtration process, the liquid flows out through the holes of the filter plate 5, and the solid residue is trapped between the filter plates 5. After filtration is completed, the hydraulic cylinder 3 retracts and the pressure plate 4 returns to its original position, which facilitates unloading and cleaning of the filter plate 5.

[0042] The auxiliary mechanism is used to precisely control the position of the locking sleeve 14, thereby achieving a more precise fixing operation. The control sleeve 21 is rotatably mounted on the outside of the fixing sleeve 10. The internal gear ring 22 at its bottom end meshes with the gear 24 at the top of the multiple sets of screws 23. When the control sleeve 21 rotates, the screw 23 is driven to rotate through the transmission of the internal gear ring 22 and the gear 24. The screw 23 is threadedly connected to the locking sleeve 14, so the rotation of the screw 23 is converted into the up and down movement of the locking sleeve 14. The setting of the annular groove 25, the limiting block 26 and the limiting groove 27 realizes the precise positioning of the control sleeve 21. The push spring 28 between the top of the multiple sets of limiting blocks 26 and the inner wall of the annular groove 25 ensures the automatic return of the limiting block 26. This design allows the operator to precisely control the position of the locking sleeve 14 by rotating the control sleeve 21, thereby better adjusting the locking degree of the fixing mechanism.
