Description

Technical Field

[0001] This invention belongs to the field of filtration, specifically a step-by-step filtration mechanism, and relates to a step-by-step filtration mechanism for soybean lecithin with an automatic discharge function. Background Technology

[0002] Soy lecithin is a common food additive, also known as soybean lecithin or soybean phospholipid. It is a natural phospholipid extracted from soybeans and is mainly composed of lecithin, choline, inositol, etc. It is widely used in the food industry. In general, soybean lecithin is a commonly used food additive with good emulsifying and stability properties, and plays an important role in food processing and quality improvement.

[0003] After soybean lecithin undergoes multi-stage filtration, the discharge direction and position are fixed, making it impossible to flexibly change the discharge position according to the location of the receiving hopper and other receiving objects. The discharge mechanism lacks flexibility in use, and if either the filtration device or the discharge mechanism malfunctions, they are usually discarded together because they are inconvenient to separate, resulting in cost waste.

[0004] In summary, the present invention provides a step-by-step filtration mechanism for soybean lecithin with automatic discharge function to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a method for cooking rice, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0007] A step-by-step filtration mechanism for soybean lecithin with automatic discharge function includes:

[0008] A filter housing is provided, with a discharge hopper fixed below it. A discharge assembly is provided below the discharge hopper. The discharge assembly includes an automatic discharge component, a multi-directional discharge component, an anti-stacking component, and a support component. The automatic discharge component controls the discharge of soybean lecithin from the filter housing. The multi-directional discharge component changes the discharge direction of soybean lecithin. The anti-stacking component prevents soybean lecithin from accumulating and adhering inside the automatic discharge component. The support component connects the automatic discharge component to the bottom of the discharge hopper.

[0009] The discharge component 3 can not only achieve automatic discharge, but also flexibly change the discharge direction and position, as well as the sufficiency of discharge. It can also quickly disassemble and install the discharge component from the filter shell, reducing the overall cost waste of the equipment after it is scrapped.

[0010] Optionally, the automatic discharge component includes a discharge hopper, with an opening and closing support frame fixed below the discharge hopper. A support groove is provided on the inner side of the opening and closing support frame, and an opening and closing plate is slidably installed inside the support groove. A connecting rod is fixed on one side of the opening and closing plate, and a pressure sensor is fixed inside the opening and closing plate. Two cylinders are fixed on the outside of the opening and closing support frame, and one end of the telescopic rod of each of the two cylinders is fixed to one side of the connecting rod.

[0011] Once the pressure sensor detects that a certain weight of material has accumulated above the opening and closing plate, the cylinder can be activated to open the opening and closing plate to achieve automatic material discharge.

[0012] Optionally, the multi-directional discharge component includes an annular support plate fixed below the discharge hopper. The outer surface of the annular support plate has multiple slots, and the lower part of the annular support plate has an annular sliding groove. An arc-shaped connecting plate is slidably installed inside the annular sliding groove. The arc-shaped connecting plate has multiple inner grooves inside, and a spring is fixed inside the inner groove. A locking head slides inside the inner groove. A feed hopper is fixed below the arc-shaped connecting plate. The feed hopper has a groove inside, and two anti-slip strip grooves are opened inside the groove. A telescopic bucket is slidably installed inside the groove, and an anti-slip strip is fixed to the bottom of the telescopic bucket.

[0013] Pulling the telescopic bucket out of the trough increases the length of the feed hopper and changes the material drop position. With the locking of the anti-slip strip and the anti-slip groove, the position of the telescopic bucket is fixed to prevent it from sliding easily.

[0014] Optionally, the anti-stacking component includes a motor, gear, annular plate, toothed ring, mounting plate, air pump, duct, high-pressure nozzle, and multiple arc-shaped filters. The gear is fixed to one end of the motor output shaft and meshes with the toothed surface of the toothed ring. The annular plate is rotatably mounted inside the discharge hopper. The toothed ring is fixed to the outside of the annular plate. The mounting plate is fixed below the annular plate. The air pump is fixed to one side of the mounting plate. The duct is fixed to the other side of the mounting plate and to the air outlet of the air pump. The high-pressure nozzle is fixed to one end of the duct. The arc-shaped filters are fixed to the outside of the discharge hopper.

[0015] The motor drives the gear to rotate, and the gear drives the mounting plate, air pump and high-pressure nozzle to rotate inside the discharge hopper through the tooth ring and ring plate. The air pump draws in air and blows it out through the high-pressure nozzle to blow the material on the inner wall of the discharge hopper out, preventing the material from adhering to the inner wall of the discharge hopper and accumulating, which would affect the smooth discharge.

[0016] Optionally, the support includes an arc-shaped support plate fixed to the outer surface of the discharge hopper. Both ends of the arc-shaped support plate are hinged to arc-shaped movable plates. A fixing plate is fixed to one end of each of the two arc-shaped movable plates, and a positioning screw is threaded between the interior of the two fixing plates.

[0017] The curved movable plate is at a 90-degree angle, and both the curved support plate and the curved movable plate have internal grooves. When the two curved movable plates are opened, the discharge hopper can be hung in the internal grooves and is limited by the two rotatable and closed curved movable plates.

[0018] Optionally, the top of the filter housing is provided with a feed inlet.

[0019] A hinged sealing plate can be attached to the feed inlet. When the device is not in use, the sealing plate can be covered to prevent foreign objects from falling into the filter housing.

[0020] Optionally, four support legs are fixed to the bottom of the filter housing.

[0021] The support legs can be equipped with casters at the bottom, making it easy to move the device to a designated location for use.

[0022] Optionally, the filter housing is provided with three sieve plates inside, and a vibration motor is fixed below each of the three sieve plates.

[0023] Soybean lecithin is fed into the filter shell through the feed inlet, and under the vibration of the vibrating motor, the soybean lecithin is sieved layer by layer through the sieve plate.

[0024] Optionally, the filter shell is provided with slag discharge ports on both sides, and a slag discharge traction plate is fixed on one side of the slag discharge port.

[0025] The material sieved through each layer of filter screen will fall out of the filter shell via the slag discharge traction plate.

[0026] Optionally, a discharge through hole is provided at the bottom of the filter shell, and the discharge hopper is connected to the discharge through hole.

[0027] This allows the sieved material to fall into the slag discharge hopper for easy discharge.

[0028] In summary, the beneficial technical effects of the present invention are as follows:

[0029] 1. Rotating the feed hopper causes the arc-shaped connecting plate to rotate in the annular groove, allowing the feed hopper's discharge direction to change flexibly. When the clamping head rotates to the corresponding slot, it is clamped into the slot by the spring force, fixing the position of the arc-shaped connecting plate and the feed hopper. The pull-out telescopic bucket can change the length of the feed hopper and the specific position of the material drop, improving the flexibility in the discharge direction and position.

[0030] 2. Unscrew one of the fixing plates by the positioning screw to release the lock of the two fixing plates. Open the two arc-shaped movable plates to the sides to remove the discharge hopper. The easy disassembly between the filter equipment and the discharge assembly can reduce the cost of replacing parts and thus reduce cost waste.

[0031] 3. Start the motor to drive the gear to rotate. The gear drives the ring plate to rotate through the toothed ring. This causes the mounting plate to drive the air pump and high-pressure nozzle to rotate inside the discharge hopper. This helps the high-pressure nozzle to blow away the material. The air pump draws in air and blows it out through the high-pressure nozzle to blow away the material on the inner wall of the discharge hopper, preventing the material from adhering to the inner wall of the discharge hopper and accumulating, which would affect the smooth discharge.

[0032] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0042] The present invention will be further described in detail below with reference to the accompanying drawings.

[0043] Reference Figure 1-2 This invention discloses a step-by-step filtration mechanism for soybean lecithin with automatic discharge function, comprising a filter shell 1 and a discharge assembly 3. A control panel is provided on the outside of the filter shell 1 for controlling the start and stop of the drive mechanism in the equipment. A discharge hopper 2 is fixed below the filter shell 1, and the discharge assembly 3 is located below the discharge hopper 2. The discharge assembly 3 includes an automatic discharge component, a multi-directional discharge component, an anti-stacking component, and a support component. The automatic discharge component controls the discharge of soybean lecithin from the filter shell 1. The multi-directional discharge component changes the discharge direction of the soybean lecithin, allowing it to be discharged in a designated direction according to requirements or the placement of the equipment. The anti-stacking component prevents soybean lecithin from accumulating and adhering inside the automatic discharge component. The support component connects the automatic discharge component to the bottom of the discharge hopper 2, facilitating quick assembly and disassembly of the discharge assembly 3 and the filtration equipment. If either the discharge assembly 3 or the filtration equipment malfunctions and cannot be repaired, the entire equipment does not need to be discarded, helping to reduce cost and resource waste.

[0044] Reference Figure 2-6In this embodiment, the automatic discharge component includes a discharge hopper 31. A U-shaped opening and closing support frame 32 is fixed below the discharge hopper 31. A support groove 33 is provided on the inner side of the opening and closing support frame 32. An opening and closing plate 34 is slidably installed inside the support groove 33. The opening and closing plate 34 seals the inside of the support groove 33 to close the discharge channel of the equipment and prevent soybean lecithin from falling out. A connecting rod 35 is fixed on one side of the opening and closing plate 34. A pressure sensor 36 is fixed inside the opening and closing plate 34. Two cylinders 37 are fixed on the outside of the opening and closing support frame 32. After the soybean lecithin above the pressure sensor 36 accumulates to a certain amount, the pressure sensor 36 transmits the detected pressure value to the controller. The controller controls the two cylinders 37 to start synchronously. One end of the telescopic rod of the two cylinders 37 is fixed to one side of the connecting rod 35. The telescopic movement of the cylinders 37 drives the opening and closing plate 34 to move through the connecting rod 35, thereby controlling the opening and closing of the discharge channel.

[0045] Reference Figure 2-6 In this embodiment, the multi-directional discharge component includes an annular support plate 38 fixed below the discharge hopper 31. The annular support plate 38 is located outside the opening and closing support frame 32, and its inner core size is much larger than that of the opening and closing support frame 32 to prevent obstruction when the opening and closing plate 34 is opened. The outer surface of the annular support plate 38 is provided with multiple slots 39, and the lower part of the annular support plate 38 is provided with an annular sliding groove 310. An arc-shaped connecting plate 311 is slidably installed inside the annular sliding groove 310. The arc-shaped connecting plate 311 is provided with multiple inner grooves 312. A spring 313 is fixed inside the inner groove 312, and a locking head 314 slides inside the inner groove 312. One end of the spring 313 is fixedly connected to the locking head 314. When the spring 313 is at its original length and no pressure is applied, the locking head 314 extends to the outside of the arc-shaped connecting plate 311, and the size of the locking head 314 is adapted to the slots 39. Under the elastic push of the spring 313, the locking head 314 will lock into the slot. The internal structure 39 automatically positions the arc-shaped connecting plate 311. A feeding hopper 315 is fixed below the arc-shaped connecting plate 311. The feeding hopper 315 is inclined to facilitate the smooth sliding out of soybean lecithin. A groove 316 is formed inside the feeding hopper 315, and two anti-displacement strip grooves 317 are formed inside the groove 316. A telescopic bucket 318 is slidably installed inside the groove 316. A handle is fixed below the telescopic bucket 318, allowing for easy application of force to move the telescopic bucket 318. Pulling out the trough 316 and the telescopic bucket 318 can change the position of soybean lecithin accumulation. The bottom of the telescopic bucket 318 is fixed with an anti-shifting strip 319. The anti-shifting strip 319 has a certain elasticity. When the telescopic bucket 318 is subjected to force and slides, the anti-shifting strip 319 will be squeezed and deformed. When it reaches the position of the anti-shifting strip groove 317, the anti-shifting strip 319 will make contact with the squeezed part. Due to its own elasticity, the anti-shifting strip 319 will return to its original shape and get stuck in the anti-shifting strip groove 317, which helps the telescopic bucket 318 to be positioned.

[0046] Reference Figure 2-6In this embodiment, the anti-stacking component includes a motor 320, a gear 321, an annular plate 322, a toothed ring 323, a mounting plate 324, an air pump 325, an exhaust pipe 326, a high-pressure nozzle 327, and multiple arc-shaped filters 328. The motor 320 and air pump 325 are connected via existing technology and an external control switch. The motor 320 is fixed to the outside of the discharge hopper 31 via a mounting bracket. One of the arc-shaped filters 328 corresponding to the gear 321 has a through groove to facilitate meshing between the gear 321 and the toothed ring 323. The gear 321 is fixed to one end of the output shaft of the motor 320, and meshes with the toothed surface of the toothed ring 323. The annular plate 322 is rotatably mounted inside the discharge hopper 31. The discharge hopper 31 has an annular groove inside. The top of the annular plate 322 slides in the annular groove by means of a connecting frame. The toothed ring 323 is fixed to the outside of the annular plate 322. The mounting plate 324 is fixed to the bottom of the annular plate 322. The air pump 325 is fixed to one side of the mounting plate 324. The air duct 326 is fixed to the other side of the mounting plate 324. The air duct 326 is fixed to the air outlet of the air pump 325. The high-pressure nozzle 327 is fixed to one end of the air duct 326. The high-pressure nozzle 327 faces the inclined inner wall of the discharge hopper 31, which can fully blow away the soybean lecithin adhering to the inner wall of the discharge hopper 31. The arc-shaped filter screen 328 is fixed to the outside of the discharge hopper 31 to prevent dust from entering and accumulating on the inner wall of the discharge hopper 31.

[0047] Reference Figure 2-6 In this embodiment, the support includes an arc-shaped support plate 329 fixed to the outer surface of the discharge hopper 2. The arc-shaped support plate 329 is 180 degrees. Both ends of the arc-shaped support plate 329 are hinged to arc-shaped movable plates 330. Each of the two arc-shaped movable plates 330 has a fixing piece 331 fixed at one end opposite to the other. The two fixing pieces 331 are threadedly connected to each other. When the two arc-shaped movable plates 330 are closed, the two fixing pieces 331 are folded up and down. The two fixing pieces 331 are connected by the positioning screw 332 to prevent the discharge assembly 3 from falling when the two arc-shaped movable plates 330 are opened.

[0048] Reference Figure 2-6 In this embodiment, the filter shell 1 has a feed inlet 4 at the top and four support legs 5 fixed at the bottom. The filter shell 1 has three sieve plates 6 inside. The inner diameter of the mesh holes of the three sieve plates 6 gradually decreases from top to bottom to improve the sieving effect. A vibration motor 7 is fixed below each of the three sieve plates 6. The vibration motor 7 drives the sieve plates 6 to vibrate, which can accelerate the sieving speed and prevent the mesh holes from clogging. The filter shell 1 has slag discharge ports 8 on both sides. A slag discharge traction plate 9 is fixed on one side of the slag discharge port 8. The filter shell 1 has a discharge through hole 10 at the bottom. The discharge hopper 2 is connected to the discharge through hole 10.

[0049] In use, the material enters the discharge hopper 31 and accumulates on the opening and closing plate 34. After the pressure sensor 36 detects a certain weight, it will activate the cylinder 37. The cylinder 37 drives the opening and closing plate 34 to open through the connecting rod 35, and the material falls onto the feed hopper 315 and slides out, achieving the effect of automatic material discharge. The receiving position can be changed according to site requirements. Simply rotate the feed hopper 315, and the feed hopper 315 will drive the arc-shaped connecting plate 311 to slide in the annular slide groove 310. When the arc-shaped connecting plate 311 rotates, the clamping head 314 is squeezed into the inner groove 312 by the clamping groove 39 and the annular support plate 38. When it moves to the next corresponding clamping groove 39, it is pushed into the clamping groove 39 by the elastic force of the spring 313, completing the rotation and positioning of the arc-shaped connecting plate 311, thereby realizing the flexible change of the discharge direction of the feed hopper 315.

[0050] Holding the handle allows the telescopic bucket 318 to be pulled out of the trough 316, increasing the length of the feed hopper 315 and changing the material dropping position. With the engagement of the anti-slip strip 319 and the anti-slip groove 317, the position of the telescopic bucket 318 is fixed. When the direction of the feed hopper 315 is rotated, the telescopic bucket 318 pushes back into the trough 316 to reduce the length of the feed hopper 315, avoiding obstruction by the support leg 5 when rotating the feed hopper 315. Furthermore, the engagement and limitation of the anti-slip strip 319 and the anti-slip groove 317 prevent the telescopic bucket 318 from easily slipping out.

[0051] After discharge, the motor 320 can be started to drive the gear 321 to rotate. The gear 321 will drive the annular plate 322 to rotate through the meshing toothed ring 323. The annular plate 322 will drive the mounting plate 324, air pump 325 and high-pressure nozzle 327 to rotate inside the discharge hopper 31, which will help the high-pressure nozzle 327 to fully blow material in the discharge hopper 31. The air pump 325 draws air into the air duct 326 and blows it out through the high-pressure nozzle 327 to blow the material on the inner wall of the discharge hopper 31, preventing the material from adhering to the inner wall of the discharge hopper 31 and accumulating, which will affect the smooth discharge.

[0052] If any set of the filter equipment or discharge assembly 3 malfunctions and becomes unusable, the positioning screw 332 can be unscrewed to remove one of the fixing plates 331, releasing the locks of both fixing plates 331. The two arc-shaped movable plates 330 can then be opened to the sides to remove the discharge hopper 31. The unusable filter equipment or discharge assembly 3 can then be replaced and reused. The ease of disassembly between the filter equipment and discharge assembly 3 reduces the cost of replacing parts, thereby reducing cost waste.

Anyone should understand that structural changes made under the guidance of this invention, and any technical solutions that are the same as or similar to this invention, fall within the protection scope of this invention. Technical aspects, shapes, and structures not described in detail in this invention are all publicly known technologies.
