A filtration mechanism for phospholipid production

Abstract

A filtration mechanism for phospholipid production includes a base frame, a fixing component on the base frame, a limiting component on the fixing component, and a transmission component on the base frame. This utility model, as a filtration mechanism for phospholipid production, uses a rotating frame driven gear transmission system through the fixing component to precisely convert rotational motion into synchronous rotation of a double-ended threaded rod. Linear guidance by a guide rod causes coordinated relative displacement of symmetrically arranged clamping frames, forming a stable and reliable clamping force to firmly fix the filter screen to the filter housing. This design abandons the traditional bolt fixing method, achieving filter screen installation and removal with single-handed operation through an optimized mechanical transmission chain, significantly improving maintenance efficiency. The gear-threaded rod composite transmission mechanism ensures uniform distribution of clamping force, completely avoiding localized stress concentration while guaranteeing reliable fixation. The symmetrical clamping structure ensures balanced force on the filter screen.

Description

Technical Field

[0001] This utility model relates to the technical field of phospholipid processing equipment, specifically to a filtration mechanism for phospholipid production. Background Technology

[0002] Phospholipids, also known as phospholipids or phospholipid lipids, are lipids containing phosphoric acid. They are complex lipids and are the main components of biological membranes. They are divided into two main categories: glycerophospholipids and sphingomyelins, which are composed of glycerol and sphingosine, respectively. Phospholipids are amphoteric molecules, with one end being a hydrophilic nitrogen or phosphorus-containing head and the other end being a hydrophobic (lipophilic) long hydrocarbon chain. For this reason, the hydrophilic ends of phospholipid molecules are close to each other, and the hydrophobic ends are close to each other. They often work together with other molecules such as proteins, glycolipids, and cholesterol to form the phospholipid bilayer, which is the structure of the cell membrane.

[0003] In the production and processing of phospholipids, filtration is essential to ensure product quality and effectively remove various impurities. This crucial process significantly improves the purity of the final product. Currently, conventional filtration systems commonly use filter screens, which are bolted to the main structure of the filtration unit. However, in actual production, with prolonged operation, impurities inevitably accumulate and clog the surface and pores of the filter screen, necessitating thorough cleaning and maintenance. Traditional bolt-fixing methods are inherently cumbersome and time-consuming during disassembly, severely limiting the maintenance efficiency of the filtration system and consequently affecting the overall production line's operational efficiency. This limitation in structural design directly leads to increased equipment downtime and reduced production efficiency. Utility Model Content

[0004] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a filtration mechanism for phospholipid production.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A filtration mechanism for phospholipid production includes a base frame, a fixing component on the base frame, a limiting component on the fixing component, a transmission component on the base frame, a filter box on the fixing component, a filter screen movably mounted on the filter box, a fixing frame on the filter box, a double-ended threaded rod movably mounted on the fixing frame, a guide rod on the fixing frame, a clamping frame movably mounted on the double-ended threaded rod and movably connected to the guide rod, and a drive component on the fixing frame.

[0007] Preferably, the base frame is provided with feet.

[0008] Preferably, the drive assembly includes a rotating frame and a first gear. The rotating frame is movably mounted on the fixed frame, the first gear is mounted on the double-threaded rod, and the rotating frame is provided with a second gear that meshes with the first gear.

[0009] Preferably, the rotating frame is provided with anti-slip texture.

[0010] Preferably, the limiting component includes a locking hole and a working box. The locking hole is disposed on the fixed frame, the working box is mounted on the rotating frame, a sliding plate is movably disposed inside the working box, a moving rod is disposed on the sliding plate, a spring is disposed on the sliding plate and the spring abuts against the side wall of the working box, and a limiting shaft is disposed on the sliding plate and the limiting shaft abuts against the locking hole.

[0011] Preferably, the card slot has a plurality of holes.

[0012] Preferably, the transmission assembly includes a rotating shaft and an auxiliary wheel. The auxiliary wheel is mounted on the base frame, and a movable plate is movably mounted on the auxiliary wheel. The rotating shaft is movably mounted on the base frame, and a crank is mounted on the rotating shaft. A connecting rod is movably mounted on the crank and is movably connected to the movable plate. A first pulley is mounted on the rotating shaft, and a motor is mounted on the base frame. A second pulley is mounted on the drive end of the motor, and a transmission belt is mounted on the first pulley and the second pulley.

[0013] Preferably, the filter box is equipped with a feed hopper.

[0014] The beneficial effects of this utility model are as follows: As a filtration mechanism for phospholipid production, this utility model, through a fixed component and a rotating frame driven gear transmission system, precisely converts rotational motion into synchronous rotation of a double-ended threaded rod. Linear guidance by a guide rod causes coordinated relative displacement of the symmetrically arranged clamping frames, forming a stable and reliable clamping force to firmly fix the filter screen to the filter housing. This design abandons the traditional bolt fixing method, and through an optimized mechanical transmission chain, allows for single-handed operation to install and remove the filter screen, significantly improving maintenance efficiency. The gear-threaded rod composite transmission mechanism ensures uniform distribution of clamping force, completely avoiding localized stress concentration while guaranteeing reliable fixation. The symmetrical clamping structure ensures balanced force on the filter screen. Through a limiting component, the rotating frame driven gear transmission system drives the clamping frames to complete the initial clamping, while the innovative spring-slide mechanism achieves precise disengagement of the limiting shaft through the traction of the moving rod. After clamping, the spring automatically resets, pushing the limiting shaft and the locking hole to form a secondary mechanical interlock. This dual-protection mechanism ensures stable fixation of the filter screen by the clamping frame, while the rigid locking of the limiting shaft effectively eliminates the risk of vibration loosening during equipment operation. The spring-buffered design makes the locking process smooth and reliable, avoiding the impact damage that may be caused by traditional rigid locking. Through the transmission components, the filter frame reciprocating drive system achieves efficient dynamic filtration through an optimized mechanical transmission design: the motor-driven pulley transmission system smoothly transmits rotational motion to the crank-connecting rod mechanism, precisely converting it into the linear reciprocating motion of the filter frame. The innovative multi-stage transmission structure ensures maximum motion conversion efficiency, and the auxiliary wheel guide system significantly reduces moving friction resistance, making the reciprocating motion smoother and more fluid. This dynamic filtration mechanism effectively breaks down the phospholipid buildup on the filter screen surface, continuously renewing the filtration interface, significantly improving filtration throughput and preventing filter pore clogging. During system operation, the constant reciprocating frequency and stroke are precisely calculated, ensuring filtration efficiency while avoiding mechanical damage to the filter screen structure.

The fixed frame 6 is equipped with a drive assembly, and there is a pair of clamping frames 9. The pair of clamping frames 9 are respectively located at both ends of the double-ended threaded rod 7. The threads at both ends of the double-ended threaded rod 7 are in opposite directions. The double-ended threaded rod 7 can drive the pair of clamping frames 9 to move closer or further apart. When the filter screen 5 is placed on the filter box 4, the double-ended threaded rod 7 rotates, which can drive the pair of clamping frames 9 to move on the guide rod 8. The pair of clamping frames 9 move closer together, thereby fixing the filter screen 5 on the filter box 4. When disassembly is required, the pair of clamping frames 9 are moved further apart to facilitate the removal of the filter screen 5 from the filter box 4.

[0024] Advantageously, the base frame 1 is provided with pads, which are located near the placement plane of the base frame 1, so that the base frame 1 can be placed stably.

Rotating the rotating frame 11 can drive the second gear 12 to rotate, which in turn drives the first gear 10 to rotate, and the first gear 10 can drive the double-ended threaded rod 7 to rotate.

[0026] Advantageously, the rotating frame 11 is provided with anti-slip texture, which makes it less likely for the operator to slip their hand when using the rotating frame 11.

[0027] Advantageously, the limiting assembly includes a locking hole 13 and a working box 14. The locking hole 13 is located on the fixed frame 6, and the working box 14 is mounted on the rotating frame 11. A sliding plate 15 is movably disposed inside the working box 14. A moving rod 17 is provided on the sliding plate 15. A spring 16 is provided on the sliding plate 15 and abuts against the side wall of the working box 14. A limiting shaft 18 is provided on the sliding plate 15 and abuts against the locking hole 13. Pulling the moving rod 17 can drive the sliding plate 15 to move inside the working box 14. At this time, the spring 16 is compressed, and the limiting shaft 18 moves away from the locking hole 13 along with the sliding plate 15. When it is necessary to limit and fix a pair of clamping frames 9, the moving rod 17 is released, the spring 16 returns to its original position, and the sliding plate 15 moves into the locking hole 13 along with the spring 16 and the limiting shaft 18, thereby fixing a pair of clamping frames 9.

[0028] Advantageously, the card holes 13 are provided in a plurality of manner, which facilitates the fixing of the clamping frame 9 at different positions.

[0029] Advantageously, the transmission assembly includes a rotating shaft 19 and an auxiliary wheel 2. The auxiliary wheel 2 is mounted on the base frame 1, and a movable plate 3 is movably mounted on the auxiliary wheel 2.

The filter frame is equipped with a transmission belt 25 on the second pulley 24 and the second pulley 25. When it is necessary to drive the filter frame to move back and forth to improve the filtration efficiency, the drive motor 23 is used. The motor 23 can drive the second pulley 24 to rotate. Under the action of the second pulley 24, the transmission belt 25 drives the first pulley 20 to rotate. The first pulley 20 can drive the rotating shaft 19 to rotate. The rotating shaft 19 can drive the crank 21 to rotate. The crank 21 drives the moving plate 3 on the connecting rod 22 to move back and forth on the auxiliary wheel 2. The moving plate 3 drives the filter frame to move back and forth, which can prevent the accumulation of phospholipids on the filter screen from affecting the filtration efficiency.

[0030] Advantageously, the filter box 4 is provided with a feed hopper 26, which facilitates the entry of phospholipids into the filter box 4.

[0031] Working principle of this utility model:

[0032] First, when installing the filter screen, rotate the rotating frame 11. The rotating frame 11 drives the second gear 12 to rotate, which in turn drives the first gear 10 to rotate. The first gear 10 drives the double-threaded rod 7 to rotate, which in turn drives a pair of clamping frames 9 to move on the guide rod 8. The pair of clamping frames 9 move closer to each other, thus fixing the filter screen 5 onto the filter box 4. When disassembly is required, move the pair of clamping frames 9 away from each other to facilitate removing the filter screen 5 from the filter box 4. When rotating the rotating frame 11, pull the moving rod 17. The moving rod 17 drives the sliding plate 15 to move inside the working box 14. At this time, the spring 16 is compressed, and the limiting shaft 18 moves away from the locking hole 13 along with the sliding plate 15. After the filter screen 5 is fixed, the moving rod 17 is released, the spring 16 returns to its original position, and the sliding plate 15 follows the spring 16 to move the limiting shaft 18 into the locking hole 13, thereby fixing a pair of clamping frames 9 to prevent the filter screen from loosening during operation. When it is necessary to drive the filter frame to move back and forth to improve filtration efficiency, the drive motor 23 is activated. The motor 23 can drive the second pulley 24 to rotate. The transmission belt 25 drives the first pulley 20 to rotate under the action of the second pulley 24. The first pulley 20 can drive the rotating shaft 19 to rotate. The rotating shaft 19 can drive the crank 21 to rotate. The crank 21 drives the moving plate 3 on the connecting rod 22 to move back and forth on the auxiliary wheel 2. The moving plate 3 drives the filter frame to move back and forth, which can prevent the accumulation of phospholipids on the filter screen from affecting the filtration efficiency.
