Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fish oil production and processing, and particularly relates to a centrifuge material collecting device for fish oil processing. BACKGROUND

[0002] In the prior art, after crude fish oil is extracted from raw materials in the process of fish oil production and processing, the crude fish oil needs to be subjected to alkali refining and deacidification to remove impurities in the crude fish oil. Alkali refining and deacidification is a deacidification method in which sodium soap is generated by neutralization reaction of a caustic soda solution and free fatty acids in crude fish oil, and then the sodium soap is precipitated in oil and separated from the oil and fat. The soap stock has strong adsorption capacity and can adsorb protein, mucilage, pigment and even mechanical impurities in the crude fish oil, so as to be precipitated together and have a good effect of removing impurities.

[0003] After alkali refining and deacidification, the crude fish oil is usually separated from impurities by a centrifuge (such as a flat plate unloading centrifuge). After the separation is completed, the impurities are adhered to the inner wall of the centrifuge. Then, the scraper of the centrifuge scrapes off the impurities, so that the impurities fall into the receiving hopper at the bottom of the centrifuge. Finally, the worker takes out the impurities in the receiving hopper.

[0004] However, the worker manually taking out the impurities in the receiving hopper is troublesome. In the process of taking out the impurities, in order to ensure the safety of the worker, the centrifuge often needs to be stopped before the worker starts work. Therefore, the centrifuge needs to be stopped for a period of time after working for a period of time, which will affect the production and processing efficiency of fish oil. In addition, the volume of the receiving hopper is usually small, so the impurities fill the receiving hopper at a high speed. Therefore, the frequency of the worker taking out the impurities in the receiving hopper is high, which leads to a high work load of the worker. SUMMARY

[0005] The present application provides a centrifuge material collecting device for fish oil processing, which can greatly reduce the burden of the worker, and can timely take out the impurities in the receiving hopper, which is helpful to the stable work of the centrifuge, so as to improve the efficiency of fish oil production and processing.

[0006] The present application provides a centrifuge material collecting device for fish oil processing, which adopts the following technical scheme:

[0007] The application discloses a centrifuge material collecting device for fish oil processing, which comprises a material receiving hopper, a material collecting pipeline, a material collecting assembly and a driving member, one end of the material collecting pipeline is connected with the material receiving hopper, the material collecting pipeline is arranged in an inclined mode, the end of the material collecting pipeline away from the material receiving hopper is an inclined upper end, and the inclined upper end of the material collecting pipeline is provided with a first discharging port; the material collecting assembly comprises a first rotating member and a spiral blade, the first rotating member is rotationally connected with the material collecting pipeline, the rotating axis of the first rotating member is parallel to the length direction of the material collecting pipeline, and the two ends of the first rotating member are located in the interiors of the material collecting pipeline and the material receiving hopper respectively; the spiral blade is arranged on the first rotating member, and the spiral of the spiral blade is arranged around the rotating axis of the first rotating member; and the driving member is arranged on the material collecting pipeline, the driving member drives the first rotating member to rotate, and the spiral blade drives impurities to move along the material collecting pipeline towards the first discharging port.

[0008] By adopting the technical scheme, after the impurities fall into the material receiving hopper, the driving member is started to drive the first rotating member to rotate, the first rotating member drives the spiral blade to rotate, the spiral blade can convey the impurities located at the bottom of the material receiving hopper into the material collecting pipeline, the impurities continue to move in the material collecting pipeline under the driving of the spiral blade, and finally are discharged from the first discharging port for collection, which can greatly reduce the burden of workers, the impurities in the material receiving hopper can be taken out in time, the centrifuge can work stably, and thus the efficiency of fish oil production and processing is improved; in addition, the material collecting pipeline is arranged in an inclined mode, which can facilitate the workers to collect the impurities discharged from the first discharging port, and can facilitate the impurities falling from the gap between the spiral blade and the inner wall of the material collecting pipeline to return to the material receiving hopper along the inner wall of the material collecting pipeline, so that the impurities remaining on the inner wall of the material collecting pipeline are reduced, and thus the probability that the spiral blade is stuck and cannot rotate due to the impurities remaining is reduced.

[0009] Optionally, a material collecting groove is formed in the bottom of the inner wall of the material receiving hopper, the material collecting pipeline is communicated with the material collecting groove, one end of the spiral blade away from the first discharging port is located in the material collecting groove, and the groove wall of the material collecting groove is flush with the inner wall of the material collecting pipeline.

[0010] By adopting the technical scheme, the impurities falling into the material receiving hopper are collected in the material collecting groove, the spiral blade can convey the impurities in the material receiving hopper into the material collecting pipeline, the efficiency of taking out the impurities is improved, and the probability that the impurities are stuck at the joint of the material collecting groove and the material collecting pipeline and cannot continue to move is reduced.

[0011] Optionally, it also includes a baffle, which is located inside the receiving hopper and above the spiral blades; the center of the baffle is higher than its two sides, and the bottom of the inner wall of the receiving hopper also has two guide surfaces, which are located on both sides of the collecting trough. The end of the guide surface near the collecting trough is an inclined lower end, and the two sides of the baffle are located above the two guide surfaces.

[0012] By adopting the above technical solution, the baffle protects the spiral blades. When impurities fall into the receiving hopper, they cannot fall directly onto the spiral blades. Instead, they first fall onto the baffle and then from both sides of the baffle onto the two guide surfaces. Finally, the impurities move along the guide surfaces into the collection trough, thereby reducing the damage to the spiral blades caused by impurities falling directly onto them. At the same time, impurities will be crushed and decomposed after falling onto the baffle, and will also be crushed and decomposed when falling from the baffle onto the guide surfaces. This reduces the direct entry of large pieces of impurities into the collection trough, making it easier for the spiral blades to move them. It also reduces the probability of blockage caused by large pieces of impurities.

[0013] Optionally, the guard member has a material leakage port at its center.

[0014] By adopting the above technical solution, when large impurities fall onto the guard, if the large impurities are not broken down by the impact, a portion of the impurities can fall onto the spiral blades through the discharge port, thereby breaking the impurities into at least two pieces. The adhesion between multiple pieces of impurities is released, allowing the large pieces of impurities to slide smoothly from both sides of the guard, thus reducing the probability that large pieces of impurities will adhere to the guard and be difficult to fall off, accelerating the speed at which impurities fall off the guard, and thus improving the efficiency of impurity removal.

[0015] Optionally, it may also include a plurality of first elastic elements, the two ends of which are respectively connected to the guard and the receiving hopper.

[0016] By adopting the above technical solution, after impurities fall onto the guard, the impact of the impurities on the guard will be absorbed by several first elastic elements, reducing the impact of the impact on the guard. At the same time, after absorbing part of the impact, the first elastic elements will cause the guard to vibrate and shake. Vibration and shaking can help the impurities fall off the guard, thereby further reducing the probability of impurities adhering to the guard.

[0017] Optionally, it also includes a plurality of guide members, which are respectively disposed on the two guide surfaces. The length direction of the guide members is parallel to the guide surface. The end of the guide member away from the guide surface has an inclined surface, and the end of the inclined surface near the collection trough is the lower inclined end. The inclination degree of adjacent inclined surfaces on the same guide surface is different.

[0018] By adopting the above technical solution, after impurities fall from the guard, they will land on the inclined surfaces of several guides. If large impurities are still present, the edges of the guide surfaces with smaller inclinations between adjacent guides will act as cutting blades due to the different inclination degrees of the adjacent guide surfaces. This will allow the large impurities that fall onto the guides to be cut, further improving the decomposition effect of the large impurities. At the same time, if large impurities fall onto the guides but are not cut and decomposed, the different inclination degrees of the adjacent inclined surfaces will cause the different speeds at which the various parts of the large impurities slide down the inclined surfaces, which will also decompose the large impurities, thereby further improving the decomposition effect of the large impurities.

[0019] Optionally, the inclined surface is inclined in a direction away from the first discharge port.

[0020] By adopting the above technical solution, the inclined surfaces on several guide members are inclined downwards both towards the direction close to the collection trough and away from the first discharge port, so that impurities falling on the inclined surfaces can move smoothly along the inclined surfaces and fall into the collection trough, thereby reducing the probability of impurities remaining at the stepped positions formed by the inclined surfaces with different inclination degrees between adjacent guide members.

[0021] Optionally, the receiving hopper has a second discharge port on the side of the collecting trough away from the receiving pipe, the second discharge port connecting the collecting trough with the space outside the receiving hopper; it also includes an end cap for controlling the opening and closing of the second discharge port, the end cap being detachably connected to the receiving hopper.

[0022] By adopting the above technical solution, the rotation of the spiral blades drives the impurities to move along the receiving pipe and remove them. After that, some impurities will remain in the collection tank at a position away from the receiving pipe. In order to reduce the impact of impurities remaining in the collection tank for a long time and deteriorating on other substances entering the centrifuge, the staff can open the end cover when the centrifuge is stopped and manually remove the remaining small amount of impurities.

[0023] Optionally, it also includes a plurality of vibration components, all of which are disposed at the bottom of the receiving pipe; each vibration component includes a movable member and a plurality of second elastic members, the movable member being slidably connected to the receiving pipe, and the plurality of second elastic members driving the movable member to slide into the receiving pipe;

[0024] It also includes a linkage component, which includes a second rotating component and several driving wheels. The second rotating component is rotatably connected to the receiving pipe, and the rotation axis of the second rotating component is parallel to the length direction of the receiving pipe. Several driving wheels are all disposed on the second rotating component, and each of the driving wheels corresponds to one of the several movable components. The driving wheel abuts against the corresponding movable component. The driving component drives the second rotating component to rotate, and the rotation of the driving wheel drives the movable component to slide back and forth.

[0025] By adopting the above technical solution, the driving component can drive the first rotating component to rotate while simultaneously driving the second rotating component to rotate. The rotation of the first rotating component drives the spiral blade to rotate, causing impurities to move. The rotation of the second rotating component drives several driving wheels to rotate. The rotation of the driving wheels drives the movable component to slide away from the spiral blade to its limit position. Then, the second elastic component will drive the movable component to slide closer to the spiral blade, causing the movable component to hit the bottom of the receiving pipe, causing the receiving pipe to vibrate. This can shake off the impurities adhering to the bottom of the inner wall of the receiving pipe, further reducing the probability of impurities remaining in the receiving pipe, and thus reducing the probability of impurities affecting the rotation of the spiral blade due to impurities remaining on the inner wall of the receiving pipe.

[0026] Optionally, the rotation of the second rotating member drives several of the drive wheels to rotate synchronously, and adjacent drive wheels cause adjacent movable members to slide in opposite directions.

[0027] By adopting the above technical solution, when a certain moving part impacts the receiving pipe, it is in an extended state. At this time, the adjacent moving part located above it will be in a retracted state. This allows impurities located between the two extended moving parts to slide down the inner wall of the receiving pipe after being vibrated and be intercepted by the moving part located below it. This allows the impurities to move along the inner wall of the receiving pipe in a certain amount of gradual sliding, thereby reducing the probability of a large number of impurities sliding down and clogging between the spiral blade and the inner wall of the receiving pipe.

[0028] In summary, this application includes at least one of the following beneficial effects:

[0029] 1. It can greatly reduce the burden on the staff, and at the same time, the impurities in the receiving hopper can be removed in time, which helps the centrifuge to work stably, thereby improving the efficiency of fish oil production and processing.

[0030] 2. It can reduce the probability of impurities damaging the spiral blades, thereby protecting the spiral blades and enabling them to work stably to move impurities.

[0031] 3. It can crush and decompose large impurities that fall into the receiving hopper, so that the rotation of the spiral blade can stably drive the impurities to move, thereby reducing the probability of large impurities causing blockage of the receiving pipe or difficulty in rotating the spiral blade.

[0032] 4. It can reduce the probability of impurities adhering to and remaining in the receiving hopper and the receiving pipe, thereby improving the effect and efficiency of impurity removal. Attached Figure Description

[0039] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0040] Reference Figure 1 This application discloses a centrifuge receiving device for fish oil processing, used to remove and collect the remaining impurities after crude fish oil has been centrifuged by centrifuge 1. In this embodiment, the centrifuge 1 for centrifuging crude fish oil is preferably a flat-plate bottom-discharge centrifuge 1. After the crude fish oil is centrifuged by centrifuge 1, the impurity-removed fish oil will be sent out through the discharge pipe. The impurities will adhere to the inner wall of centrifuge 1, and then be scraped off the inner wall by the scraper of centrifuge 1 and discharged from the bottom of centrifuge 1. Since the flat-plate bottom-discharge centrifuge 1 is an existing and common type of centrifuge 1, it will not be described in detail here, and only a brief illustration is shown in the accompanying drawings.

[0041] Reference Figure 1 and Figure 2 The receiving device includes a receiving hopper 2, a receiving pipe 3, a receiving assembly 4, and a driving component 5. The receiving hopper 2 is installed at the bottom of the centrifuge 1 and is used to initially collect impurities scraped off from the inner wall of the centrifuge 1. The receiving pipe 3 is connected to the receiving hopper 2 and is used to move and remove impurities. The receiving assembly 4 is located inside the receiving pipe 3, and the driving component 5 is installed on the receiving pipe 3. The driving component 5 provides power to the receiving assembly 4, and the receiving assembly 4 drives the impurities in the receiving hopper 2 to move along the receiving pipe 3 for discharge, thereby removing the impurities from the receiving hopper 2.

[0042] The receiving hopper 2 is fixedly connected to the centrifuge 1. The inside of the receiving hopper 2 has a cavity 21. The cavity 21 forms an opening at the top of the receiving hopper 2 and the opening communicates with the discharge port of the centrifuge 1.

[0043] The receiving pipe 3 is a cylindrical tubular structure, installed at an angle on one side of the centrifuge 1. One end of the receiving pipe 3 along its axis is fixedly connected to the bottom of the receiving hopper 2 and communicates with the bottom of the cavity 21. The other end of the receiving pipe 3 along its axis is an inclined upper end, and a first discharge port 31 is opened at the bottom of the inclined upper end of the receiving pipe 3, with a pipe section extending downward to guide the discharge of impurities. In practical applications, the operator can place a container for collecting impurities below the first discharge port 31. The impurities will be discharged from the first discharge port 31 under the operation of the receiving assembly 4 and eventually fall into the container.

[0044] To improve the structural stability of the receiving pipe 3, several support frames for supporting the receiving pipe 3 can be fixedly installed on the ground. In this embodiment, it is preferable that the number of support frames is one.

[0045] The receiving assembly 4 includes a first rotating component 41 and a spiral blade 42. The first rotating component 41 is generally cylindrical, with one end located in the receiving pipe 3 and the other end in the cavity 21. One end of the first rotating component 41 is rotatably connected to the receiving pipe 3, and the other end is rotatably connected to the receiving hopper 2. The axis of the first rotating component 41 coincides with the axis of the receiving pipe 3, and the rotation axis of the first rotating component 41 coincides with its own axis. The spiral blade 42 is generally a sheet-like structure with a spiral trajectory. The spiral blade 42 is fixedly installed on the first rotating component 41, surrounding the first rotating component 41, and the spiral trajectory of the spiral blade 42 is centered on the axis of the first rotating component 41. There are gaps between the spiral blade 42 and the inner walls of both the receiving pipe 3 and the receiving hopper 2. After the first rotating component 41 rotates, causing the spiral blade 42 to rotate, the spiral blade 42 will move impurities along its own axis. In this embodiment, the structure of the receiving assembly 4 is preferably similar to that of an auger.

[0046] The drive component 5 is fixedly installed at the upper end of the inclined receiving pipe 3. Preferably, the drive component 5 is located above the receiving pipe 3, and preferably, the drive component 5 is a servo motor. The drive component 5 drives the first rotating component 41 to rotate, and the rotation of the first rotating component 41 drives the spiral blade 42 to rotate. The rotation of the spiral blade 42 drives the impurities to move towards the first discharge port 31. The drive component 5 can drive the first rotating component 41 to rotate through gear transmission, pulley transmission, etc. In this embodiment, it is preferred that the drive component 5 drives the first rotating component 41 to rotate through pulley transmission. Preferably, the drive component 5 is signal-connected to the centrifuge 1, and the drive component 5 can also start when the centrifuge 1 is started.

[0047] At the bottom of the receiving hopper 2, a pipe section extends outward along the axis of the receiving pipe 3 at the end furthest from it, forming a rotatable connection with the first rotating component 41. A second outlet 22 is provided at the bottom of the pipe section, communicating with the cavity 21 through the pipe section. Impurities that fail to leave from the first outlet 31 due to being driven by the spiral blades 42 can slide down along the inner wall of the receiving pipe 3 and the inner wall of the receiving hopper 2 to a position close to the aforementioned pipe section. An end cap 23 for controlling the opening and closing of the second outlet 22 is detachably connected to the pipe section on the receiving hopper 2. In this embodiment, it is preferable that the end cap 23 is detachably connected to the pipe section via a rotatable connection. After the end cap 23 is rotated open, the remaining impurities can be manually removed. Since the rotatable end cap 23 is common prior art, it will not be described in detail here.

[0048] Reference Figure 3 and Figure 4 Furthermore, the bottom of the receiving hopper 2 is inclined, and the inclination direction of the inclined structure is consistent with the inclination direction of the receiving pipe 3. The receiving hopper 2 has a collection trough 24 at the bottom of the cavity 21. After impurities fall to the bottom of the receiving hopper 2, they will eventually be collected in the collection trough 24. Preferably, the cross-section of the collection trough 24 is fan-shaped (the fan angle exceeds 180°), the axis of the collection trough 24 coincides with the axis of the receiving pipe 3, the end of the receiving pipe 3 away from the first discharge port 31 is connected to the collection trough 24, and the arc-shaped wall of the collection trough 24 is flush with the inner wall of the receiving pipe 3. The end of the first rotating member 41 away from the driving member 5 passes through the collection trough 24, the end of the spiral blade 42 away from the driving member 5 is located in the collection trough 24, and the end of the collection trough 24 away from the receiving pipe 3 is connected to the second discharge port 22 through a pipe section.

[0049] Furthermore, the receiving device also includes a baffle 6, which is installed in the cavity 21. Preferably, the baffle 6 is an arc-shaped plate structure. The baffle 6 is located above the collecting trough 24. The end of the spiral blade 42 away from the driving member 5 is located between the baffle 6 and the wall of the collecting trough 24, and there is a gap between the spiral blade 42 and the baffle 6. The axis of the baffle 6 is parallel to the axis of the receiving pipe 3, and the baffle 6 is symmetrical about the plane where its own axis and the axis of the receiving pipe 3 are located.

[0050] The bottom of the receiving hopper 2 has guide surfaces 25 on both sides of the collecting trough 24. The guide surfaces 25 are parallel to the axis of the collecting trough 24 and are inclined relative to the horizontal plane. The end of the guide surface 25 closest to the collecting trough 24 is the inclined lower end. The two guide surfaces 25 are symmetrically distributed with respect to the plane where the axis of the baffle 6 and the axis of the receiving pipe 3 are located, and the two sides of the baffle 6 are located above the two guide surfaces 25 respectively.

[0051] After impurities fall into cavity 21, they will either land on the baffle 6 or the guide surface 25. Impurities landing on the baffle 6 will be broken down by the impact, reducing their size and thus lowering the probability of large impurities. The impurities will then slide along the curved surface of the baffle 6 onto the two guide surfaces 25. Upon landing on the guide surfaces 25, they will be broken down again by the impact, further reducing their size and lowering the probability of large impurities. The impurities will then slide along the guide surfaces 25 into the collection trough 24. When impurities fall directly onto the guide surfaces 25, they will receive a greater impact, resulting in better decomposition. Ultimately, the impurities will also slide along the guide surfaces 25 into the collection trough 24.

[0052] Furthermore, the center of the guard 6 is provided with a material leakage port 61 along its own axis, and the material leakage port 61 is narrowed in the direction of approaching the material collection trough 24, so that impurities can enter the material leakage port 61 and pass through. When impurities fall onto the baffle 6, some impurities can fall directly through the discharge port 61 onto the spiral blade 42 or into the collection trough 24, while the remaining impurities will fall from both sides of the baffle 6. When large impurities fall onto the baffle 6, if the large impurities are decomposed after being impacted by the baffle 6, some of the decomposed impurities can also fall directly through the discharge port 61 onto the spiral blade 42 or into the collection trough 24, while the remaining impurities will fall from both sides of the baffle 6. If the large impurities fail to decompose after being impacted by the baffle 6, since part of the large impurities is suspended at the discharge port 61, under the action of the impact force, part of the large impurities will directly pass through the discharge port 61 and separate from the other parts of the large impurities. At this time, the large impurities will be decomposed into at least two pieces, making it easier for other impurities to slide down along the baffle plate.

[0053] Furthermore, the receiving device also includes several first elastic elements 7, and the baffle 6 is movably connected to the receiving hopper 2, meaning the baffle 6 can move within the cavity 21. In this embodiment, it is preferable that the baffle 6 and the receiving hopper 2 are movably connected by a sliding connection, the sliding direction of the baffle 6 is vertical, and there is always a gap between the baffle 6 and the spiral blade 42 during the sliding process. Several first elastic elements 7 are installed vertically, and all of the first elastic elements 7 are located below the baffle 6; the two ends of the first elastic elements 7 are fixedly connected to the baffle 6 and the receiving hopper 2 respectively, and the first elastic elements 7 drive the baffle 6 to slide away from the collecting trough 24 to the limit position and hold it there; preferably, the first elastic elements 7 are compression springs.

[0054] When impurities fall onto the guard 6, the guard 6 is impacted by the impurities, and the first elastic elements 7 can buffer it, reducing the damage caused by the impact of the impurities to the guard 6. At the same time, after the guard 6 is impacted by the impurities, the guard 6 can vibrate in the vertical direction through the first elastic elements 7. The vibration can accelerate the speed at which the impurities slide off the guard 6, further reducing the probability of impurities adhering to the guard 6.

[0055] Furthermore, the receiving device also includes several guide members 8, each of which has a rectangular parallelepiped structure. The guide members 8 are respectively fixedly installed on two guide surfaces 25, and the guide members 8 on the same guide surface 25 are closely arranged along the axial direction of the receiving pipe 3. Preferably, the length direction of the guide member 8 is parallel to the width direction of the guide surface 25.

[0056] The guide member 8 has an inclined surface 81 at one end away from the guide surface 25. The inclined surface 81 is inclined along the length of the guide member 8 towards the material collection trough 24, and the end of the inclined surface 81 near the material collection trough 24 is the lower inclined end. Preferably, the inclination of the inclined surface 81 relative to the horizontal plane is greater than the inclination of the guide surface 25 relative to the horizontal plane, and the inclination of the inclined surfaces 81 on adjacent guide members 8 is different relative to the horizontal plane. In this embodiment, preferably, there are two types of guide members 8 with different inclinations of the inclined surfaces 81 relative to the horizontal plane, and the guide members 8 on the same guide surface 25 are arranged alternately according to the two types.

[0057] Because the inclination degrees of the inclined surfaces 81 of adjacent guide members 8 on the same guide surface 25 are different, there is a stepped structure between adjacent guide members 8, and the edges of the stepped structure are sharp. When large impurities fall onto several guide members 8, the sharp edges of the stepped structure can cut the large impurities, thereby further reducing the number of large impurities. When large impurities fall onto several guide members 8 but are not impacted or cut apart, the large impurities will slide down along the inclined surfaces 81. Because the inclination degrees of adjacent inclined surfaces 81 are different, the sliding speed of different parts of the large impurities in contact with different inclined surfaces 81 is different, allowing the large impurities to decompose on their own during the sliding process, and also reducing the probability of impurities adhering to other impurities to form large impurities during the sliding process.

[0058] Furthermore, while the inclined surface 81 is inclined along the length of the guide member 8 towards the direction close to the collection trough 24, the inclined surface 81 is also inclined along the width of the guide member 8 towards the direction away from the first discharge port 31. This facilitates the sliding of impurities falling onto the guide members 8 along the inclined surface 81 into the collection trough 24, and at the same time reduces the probability of impurities in the grooves formed between adjacent guide members 8 due to the step difference.

[0059] Reference Figure 2 and Figure 5 Furthermore, the receiving device also includes a linkage component 10 and several vibration components 9, all of which are installed at the bottom of the receiving pipe 3.

[0060] Several driving components are evenly distributed along the axial direction of the receiving pipe 3. The vibration component 9 includes a movable part 91 and several second elastic members 92. The movable part 91 is slidably connected to the receiving pipe 3, preferably with the sliding direction of the movable part 91 being vertical. The end of the movable part 91 near the spiral blade 42 is the vibration part 911. The movable part 91 is restricted during its sliding process. When the movable part 91 slides towards the spiral blade 42 to its limit position, the vibration part 911 can abut against the receiving pipe 3. When the movable part 91 slides away from the spiral blade 42 to its limit position, the vibration part 911 can retract into the pipe wall of the receiving pipe 3. Preferably, at this time, the end face of the vibration part 911 is flush with the inner wall of the receiving pipe 3. Several second elastic members 92 are installed at the bottom of the receiving pipe 3, and the second elastic members 92 drive the movable part 91 to slide towards the spiral blade 42 to its limit position and maintain it.

[0061] The linkage component 10 includes a second rotating component 101 and several drive wheels 102. The second rotating component 101 is rotatably connected to the receiving pipe 3. The second rotating component 101 has a cylindrical structure, and its rotation axis coincides with its own axis. The second rotating component 101 is located below the first rotating component 41, and its rotation axis is parallel to that of the first rotating component 41. The second rotating component 101 passes through the first discharge port 31 and diverts impurities at the first discharge port 31. After the drive component 5 is started, it can also control the second rotating component 101 to rotate. The end of the second rotating component 101 near the first discharge port 31 can be linked with the second rotating component 101 through gear transmission, pulley transmission, etc. In this embodiment, it is preferable that the first rotating component 41 and the second rotating component 101 are linked through pulley transmission.

[0062] In other embodiments, a protective cover for protecting the pulley transmission structure between the drive component 5 and the first rotating component 41, and the pulley transmission structure between the first rotating component 41 and the second rotating component 101, may be fixedly installed on the receiving pipe 3.

[0063] Several drive wheels 102 are fixedly mounted on the second rotating member 101. The rotation of the second rotating member 101 will drive the several drive wheels 102 to rotate synchronously. Preferably, the drive wheels 102 are cam structures. Several drive wheels 102 correspond one-to-one with several vibration components 9, and the several drive wheels 102 are evenly distributed along the axial direction of the second rotating member 101.

[0064] The end of the movable member 91 away from the helical blade 42 also has a mating part 912 for cooperating with the drive wheel 102. The mating part 912 has a clearance space 913 for the drive wheel 102 to rotate. Several drive wheels 102 are respectively located in the clearance space 913 on the corresponding movable member 91. During the rotation of the drive wheel 102, under the action of several second elastic members 92, the drive wheel 102 can maintain abutment against the inner wall of the clearance space 913 away from the vibration part 911, and the rotation of the drive wheel 102 can drive the movable member 91 to slide.

[0065] During the rotation of the drive wheel 102, the movable part 91 can overcome the force of several second elastic elements 92 and slide away from the spiral blade 42 to the limit position. After the drive wheel 102 continues to rotate, the movable part 91 will slide back to its original position under the force of several second elastic elements 92. When the movable part 91 slides towards the spiral blade 42 to the limit position, the movable part 91 will impact the bottom of the receiving pipe 3, thereby causing the receiving pipe 3 to vibrate and shake off the impurities remaining at the bottom of the inner wall of the receiving pipe 3, which helps them slide into the collection trough 24 and continue to be driven by the spiral blade 42.

[0066] Furthermore, preferably, when the movable part 91 slides to its limit position towards the spiral blade 42, the vibrating part 911 can enter the interior of the receiving pipe 3, and at this time there is a gap between the vibrating part 911 and the spiral blade 42. Simultaneously, preferably, the vibrating part 911 has an overall arc-shaped strip structure, so that when the vibrating part 911 enters the interior of the receiving pipe 3, it can intercept impurities sliding down the bottom of the inner wall of the receiving pipe 3.

[0067] Preferably, during the rotation of the second rotating member 101, which drives several driving wheels 102 to rotate, the sliding directions of adjacent moving members 91 are opposite, and when one moving member 91 slides to a limit position, the adjacent moving member 91 will slide to another limit position. This ensures that during the movement of several moving members 91, when some moving members 91 hit the bottom of the receiving pipe 3, some moving members 91 will also intercept impurities in the receiving pipe 3. This results in a certain amount of impurities remaining at the bottom of the inner wall of the receiving pipe 3 intermittently sliding down. The amount of impurities intercepted by the vibrating part 911 is the amount of impurities that intermittently slide down, thereby reducing the probability that the rotation of the spiral blade 42 will be affected due to the simultaneous sliding down of impurities and blockage between the spiral blade 42 and the receiving pipe 3.

[0068] The implementation principle of a centrifuge receiving device for fish oil processing according to an embodiment of this application is as follows:

[0069] After being scraped off, the impurities fall into the cavity 21 of the collecting hopper. After falling onto the baffle plate or several guide members 8, large impurities can be broken down, making it easier for the subsequent spiral blades 42 to move the impurities. Then, the impurities will enter the collecting trough 24 along the inclined surface 81 of the guide member 8. When the driving member 5 drives the first rotating member 41 to rotate, driving the spiral blades 42 to rotate, the spiral blades 42 drive the impurities in the collecting trough 24 to move into the receiving pipe 3. After moving along the receiving pipe 3, the impurities are discharged from the first discharge port 31 for collection. At the same time, the driving member 5 will drive the second rotating member 101 to rotate, driving several driving wheels 102 to rotate, thereby driving several moving parts 91 to slide back and forth, so that the impurities remaining at the bottom of the inner wall of the receiving pipe 3 can stably slide down into the collecting trough 24 to continue to participate in the conveying. Finally, after confirming that the centrifuge 1 has stopped, the staff will open the end cover 23 and take out the small amount of impurities remaining in the collecting trough 24 through the second discharge port 22.

[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
