Description

Technical Field

[0001] The present application relates to the technical field of fish oil production and processing, and in particular to a fish oil sedimentation tank facilitating impurity discharge. Background Art

[0002] During the production and processing of fish oil, the purity of fish oil needs to be initially improved by the method of static precipitation. Usually, fish oil is placed in a sedimentation tank. After the fish oil stands in the sedimentation tank for a period of time, the impurities in the fish oil will deposit at the bottom of the sedimentation tank, causing the fish oil to stratify. The upper layer is the fish oil with higher purity, and the lower layer is the useless impurities. After the fish oil has been precipitated in the sedimentation tank, the impurities deposited at the bottom of the sedimentation tank are discharged, and the initial purification of the fish oil can be achieved.

[0003] Currently, for fish oil sedimentation tanks, since the tank body has a flat-bottom design with advantages such as simple structure, less material consumption, convenient installation, and stable center of gravity, it is deeply welcomed by technical designers and users. Therefore, the existing fish oil sedimentation tanks generally have a flat-bottom structure.

[0004] However, during the process of discharging the impurities deposited at the bottom of the fish oil sedimentation tank with a flat-bottom structure, the impurities are likely to remain on the plane at the bottom of the sedimentation tank, resulting in incomplete discharge of the precipitated impurities, thereby affecting the effect of the initial purification of fish oil. Summary of the Invention

[0005] The present application provides a fish oil sedimentation tank facilitating impurity discharge, which can facilitate the discharge of the impurities precipitated in the fish oil without changing the flat-bottom design of the tank body, and can reduce the residue of impurities in the sedimentation tank at the same time.

[0006] The present application provides a fish oil sedimentation tank facilitating impurity discharge, adopting the following technical solution:

[0007] A fish oil sedimentation tank facilitating impurity discharge includes a tank body. The tank body is vertically arranged, and the interior of the tank body has a cavity. An inlet is opened at the top of the tank body, and an outlet is opened at the bottom of the tank body. Both the inlet and the outlet communicate with the cavity. It further includes a impurity discharge device. The impurity discharge device includes a impurity discharge hopper. The impurity discharge hopper is located in the cavity and is slidably connected to the tank body in the vertical direction, and the impurity discharge hopper is buoyed in the fish oil. The impurity discharge hopper includes a guiding part and a impurity discharge part. The guiding part is in a funnel shape. The flared end of the guiding part abuts against the circumferential side wall of the cavity. The narrowed end of the guiding part is connected to one end of the impurity discharge part. The other end of the impurity discharge part is connected to the tank body and communicates with the outlet.

[0008] The impurity removal device also includes a plurality of connecting pieces, which are arranged on the guide part. The connecting pieces are provided with a plurality of connecting holes. The aperture of the connecting holes is smaller than the size of the impurity particles, and the inner space and the outer space of the guide part are connected through the plurality of connecting holes.

[0009] By adopting the above technical solution, after the fish oil enters the cavity, if the fish oil contains less impurities, the impurities precipitated from the fish oil will directly enter the interior of the impurity discharge part along the guide part, and be located in the interior of the guide part near the discharge port, controlling the impurities to be directly discharged when the impurities are discharged from the discharge port, thereby improving the effect of impurity discharge and reducing the waste of fish oil caused by the discharge of impurities; if the fish oil contains more impurities, the impurities precipitated from the fish oil will fill the interior of the impurity discharge part along the guide part, and the excess impurities will be located in the interior of the guide part, and the force exerted by the gravity of the impurities on the guide part will drive the impurity discharge bucket to slide downward, and the fish oil content above the impurities will be reduced. Increase, control impurities from the discharge port, the fish oil above the impurities to the impurities discharge effect of strengthening the promotion, can speed up the impurity discharge, improve the efficiency of impurity discharge, and when the impurities are discharged into the guide part without impurities, the movement direction of the fish oil above the impurities is opposite to the sliding direction of the impurity discharge bucket, so that the fish oil movement can flush the impurities adhered to the guide part into the impurity discharge part, thereby reducing impurity residue; at the same time, in the process of the impurity discharge bucket sliding downward, the volume of the space around the impurity discharge bucket is reduced, which will drive the fish oil in the space to pass through the guide part upward through the several connecting holes on the connecting piece, thereby further reducing the probability of impurities adhering to the inner surface of the guide part.

[0010] Optionally, the impurity discharge device further comprises a material blocking member and a shielding member, wherein the material blocking member is provided with a plurality of material through holes, the material blocking member is arranged on a side of the guide portion away from the impurity discharge portion, and the peripheral edge is connected to the inner surface of the guide portion; the shielding member is provided with a plurality of material leakage holes, the shielding member is arranged on a side of the material blocking member close to the impurity discharge portion, and the shielding member is movably connected to the material blocking member;

[0011] The blocking member moves relative to the material blocking member and slides with the debris discharge bucket. When the debris discharge bucket slides to the extreme position in the direction away from the discharge port, the material blocking member covers the leakage holes. After the debris discharge bucket slides in the direction close to the discharge port, the leakage holes are respectively connected with the through holes.

[0012] By adopting the above technical solution, after the fish oil enters the cavity, the impurities precipitated from the fish oil will fall onto the baffle along the guiding part. When the impurities above the baffle reach a certain amount, the gravitational force of the impurities will exert a downward force on the baffle, thereby driving the impurity discharging hopper to slide downward. The downward sliding of the impurity discharging hopper will drive the shielding part to move relative to the material blocking part, making the material leakage hole communicate with the material passing hole, so that the impurities can enter the inside of the guiding part through the material passing hole and the material leakage hole in sequence. After the impurities on the baffle are reduced, the impurity discharging hopper will slide upward to reset; during the up and down sliding of the impurity discharging hopper, the fish oil in the space around the impurity discharging hopper will pass through several communication holes on the communicating part and pass through the guiding part multiple times, thereby further reducing the probability of impurities adhering to the guiding part; moreover, after the material leakage hole communicates with the material passing hole, the continuous downward sliding of the impurity discharging hopper can drive the fish oil below the shielding part to move above the material blocking part through the material passing hole and the material leakage hole, thereby having a dredging effect on both the material passing hole and the material leakage hole, and being able to reduce the probability of both being blocked by impurities, ensuring that the impurities can smoothly enter the inside of the impurity discharging part.

[0013] Optionally, the impurity discharging device further includes a guiding part, the guiding part is located in the cavity near the discharge port, the guiding part is connected to the tank body, and one end of the impurity discharging part far from the guiding part is in vertical through-fit with the guiding part.

[0014] By adopting the above technical solution, during the sliding of the impurity discharging hopper relative to the tank body, the guiding part keeps sleeved and matched with the guiding part, which has a guiding effect on the sliding of the impurity discharging hopper, can make the sliding process of the impurity discharging hopper smoother, and reduce the probability of the impurity discharging hopper getting stuck during the sliding process.

[0015] Optionally, the impurity discharging device further includes a support frame and a sleeve. The support frame is arranged inside the guiding part and connected to the guiding part, and the sleeve is arranged on the support frame; the shielding part is rotatably connected to the material blocking part, the rotation axis of the shielding part coincides with the axis of the impurity discharging hopper, and the shielding part extends towards one end close to the discharge port along its rotation axis with an extension part, and the extension part passes through the sleeve and is in threaded fit with the sleeve.

[0016] By adopting the above technical solution, during the downward sliding of the impurity discharging hopper, the extension part will move downward relative to the sleeve, and at the same time the extension part will rotate relative to the sleeve, thereby driving the shielding part to rotate relative to the material blocking part; during the process that the material leakage hole communicates with the material passing hole as the impurity discharging hopper slides downward, the caliber of the communication between the material leakage hole and the material passing hole gradually increases, which can make the impurities above the baffle move slowly through the shielding part, thereby reducing the probability of the impurities forming a blockage when passing through the material leakage hole, and further ensuring that the impurities can smoothly pass through the material passing hole and the material leakage hole and enter the inside of the impurity discharging part.

[0017] Optionally, when the debris discharge hopper slides to an extreme position toward the discharge port, one end of the debris discharge portion away from the guide portion abuts against the support frame, and a plurality of the leakage holes are aligned and communicated with a plurality of the through holes.

[0018] By adopting the above technical solution, the support member plays a limiting role in the process of the debris bucket sliding downward; when the support member limits the debris bucket from continuing to slide, the shielding member rotates relative to the material blocking member until the leakage hole and the material through hole are aligned and connected. At this time, impurities can pass through the material through hole and the leakage hole at the fastest speed, and at the same time, the probability of the speed of impurities passing through the leakage hole being affected by excessive rotation of the shielding member relative to the material blocking member can be reduced.

[0019] Optionally, it also includes a plurality of first vibration components, which are respectively arranged on the periphery of the shielding member, and the first vibration components include a first vibration member and a first elastic member. The first vibration member is slidably connected to the shielding member, and the first elastic member drives the first vibration member to slide toward the direction close to the guide part, and the guide part is provided with a plurality of first matching grooves for the first vibration members to slide into.

[0020] By adopting the above technical solution, when the debris bucket slides downward to drive the shielding member to rotate relative to the material blocking member, the positions of several first vibration components relative to the guide part change, so that several first vibration members all enter and exit different first matching grooves under the action of the corresponding first elastic members, and each time the first vibration member enters the first matching groove, it can hit the guide part, thereby causing the guide part to vibrate, promoting the guide part to shake off impurities adhering to the inner surface of the guide part, and further reducing residual impurities.

[0021] Optionally, the support frame includes a plurality of support members, through openings for impurities to pass through are formed between adjacent support members, and the end surfaces of the support members facing away from the discharge port are all inclined surfaces.

[0022] By adopting the above technical solution, the support member forms several openings for impurities to pass through at the connecting position between the cavity and the discharge port. In the process of controlling the discharge of impurities from the discharge port, the support member can separate the impurities into several streams of fluid for discharge. At the same time, the inclined surface can also help the discharge of impurities, reducing the amount of impurities remaining on the support frame, thereby further accelerating the efficiency of impurity discharge.

[0023] Optionally, it also includes a plurality of second vibration components, which are respectively arranged on the guide member, and the second vibration components include a second vibration member and a second elastic member. The second vibration member is slidably connected to the guide member, and the second elastic member drives the second vibration member to slide toward the direction close to the debris removal part. The debris removal part is provided with a plurality of second matching grooves for the second vibration members to slide into.

[0024] By adopting the above technical solution, during the process of the impurity removal hopper sliding downward, the position of the impurity removal part changes relative to several positions, so that several second vibrating members enter and exit different second fitting grooves under the action of the corresponding second elastic members, and each time the second vibrating member enters the second fitting groove, it can strike the impurity removal part, thereby causing the impurity removal part to vibrate, promoting the impurity removal part to shake off the impurities adhering to the inner surface of the impurity removal part, and further reducing the residue of impurities.

[0025] Optionally, the position of the connecting member on the guiding part is located on the side of the material blocking member away from the discharge port.

[0026] By adopting the above technical solution, during the process of controlling the discharge of impurities from the discharge port, it is possible to reduce the fish oil in the space around the impurity removal hopper from passing upward through the guiding part through several connecting holes on the connecting member and being discharged together with the impurities, thereby further reducing the waste of fish oil during the impurity removal process.

[0027] Optionally, it further includes several third elastic members, the third elastic members are arranged on the tank body, and the third elastic members drive the impurity removal hopper to slide in a direction away from the discharge port to the limit position and stay.

[0028] By adopting the above technical solution, after the force applied by the impurities to the impurity removal hopper decreases, several third elastic members can apply assistance to the process of the impurity removal hopper sliding in a direction away from the discharge port to the limit position, thereby ensuring that the impurity removal hopper can quickly reset after the impurities enter the inside of the impurity removal part, and reducing the probability that the impurity removal hopper cannot slide back into place or gets stuck due to too much resistance from the fish oil and impurities during the reset process.

[0029] In summary, the present application includes at least one of the following beneficial effects:

[0030] 1. Without changing the flat-bottom design of the tank body, it is convenient to discharge the impurities precipitated in the fish oil, reduce the residue of impurities in the precipitation tank, and thus improve the efficiency and effect of impurity discharge after fish oil precipitation;

[0031] 2. During the process of controlling the discharge of impurities, it is possible to reduce the discharge of fish oil together with the impurities, thereby reducing the waste of fish oil and further improving the effect of impurity discharge;

[0032] 3. It is possible to reduce the probability of impurities remaining or forming blockages in the tank body by means of the flow of fish oil, and at the same time, it is possible to shake off the impurities adhering in the tank body by applying vibration, which is convenient for thorough impurity discharge.

Detailed Description of the Invention

[0039] The following further describes the present application in detail Figures 1-5 with reference to the accompanying drawings.

[0040] Referring to Figure 1 and Figure 2 , an embodiment of the present application discloses a fish oil precipitation tank facilitating impurity discharge, including a tank body 1, an impurity discharge device 2, a plurality of first vibration assemblies 3 and a plurality of second vibration assemblies 4. After fish oil is placed in the tank body 1, it is left to stand and precipitate inside the tank body 1 so that impurities are concentrated and separated out at the bottom of the tank body 1; the impurity discharge device 2 is installed inside the tank body 1 and near the bottom of the tank body 1, and the impurity discharge device 2 is used to guide the concentrated collection of impurities and assist in their discharge; a plurality of first vibration assemblies 3 and a plurality of second assemblies are both installed inside the tank body 1 and are used to apply vibrations to the impurity discharge device 2, thereby reducing the adhesion of impurities to the impurity discharge device 2, facilitating the discharge of impurities, and further improving the effect and efficiency of impurity discharge.

[0041] Preferably, the whole tank body 1 is of a cylindrical structure, that is, the tank body 1 has a flat bottom structure. There is a cavity 11 for storing fish oil inside the tank body 1. The shape of the cavity 11 is also cylindrical as a whole, and the axis of the tank body 1 coincides with the axis of the cavity 11. An inlet 12 communicating with the cavity 11 is provided at the top of the tank body 1, and an outlet 13 communicating with the cavity 11 is provided at the bottom of the tank body 1. A end cover 14 is installed at the inlet 12 of the tank body 1. The end cover 14 is detachably connected to the tank body 1. Preferably, the end cover 14 is detachably connected to the tank body 1 by means of a rotational connection. By controlling the rotation of the end cover 14, the opening or closing of the inlet 12 can be controlled; a discharge pipe 15 is installed at the outlet 13 of the tank body 1. One end of the discharge pipe 15 is fixedly connected to the tank body 1 and communicates with the cavity 11 through the outlet 13. The other end of the discharge pipe 15 leads to a device for collecting and processing impurities, and a valve 16 is installed at a position of the discharge pipe 15 close to the outlet 13, which is convenient for the staff to control the discharge of impurities from the outlet 13. Since both the end cover 14 and the valve 16 are common existing technologies, they will not be elaborated here and are only briefly shown in the drawings. In this embodiment, preferably, the axes of both the inlet 12 and the outlet 13 coincide with the axis of the tank body 1.

[0042] The bottom of the tank body 1 also has several support feet 17. The tank body 1 is placed on the ground through the several support feet 17. At this time, the tank body 1 is suspended in a vertical state.

[0043] Refer to Figure 2 and Figure 3 As shown in FIGS. and, the impurity removal device 2 includes an impurity removal hopper 21, a guide member 22 and several connecting members 23. Among them, the guide member 22 is of a cylindrical structure. The guide member 22 is located at the bottom of the cavity 11. One end in the axial direction of the guide member 22 is fixedly connected to the tank body 1. The inner diameter dimension of the guide member 22 is equal to the caliber dimension of the outlet 13, and the axis of the guide member 22 coincides with the axis of the outlet 13.

[0044] The impurity removal hopper 21 includes a guiding portion 211 and an impurity removal portion 212. The guiding portion 211 is of an overall funnel-shaped structure, and the impurity removal portion 212 is of an overall cylindrical structure. The reduced end of the guiding portion 211 is fixedly connected to one end in the axial direction of the impurity removal portion 212, and the inner diameter dimension of the reduced end of the guiding portion 211 is equal to the inner diameter dimension of the impurity removal portion 212.

[0045] After the impurity removal hopper 21 is installed in the cavity 11, the peripheral edge of the flared end of the guiding portion 211 fits and abuts against the peripheral side wall of the cavity 11, and the impurity removal portion 212 is in a penetrating fit with the guide member 22. The impurity removal hopper 21 is slidably connected to the tank body 1 along the axial direction of the tank body 1, and the guide member 22 can guide the stable sliding of the impurity removal hopper 21.

[0046] During the sliding process of the impurity removal hopper 21 relative to the tank body 1, there are limitations. When the impurity removal hopper 21 slides in the direction away from the discharge port 13 to the extreme position, the impurity removal part 212 still passes through and cooperates with the guiding member 22; when the impurity removal hopper 21 slides in the direction close to the discharge port 13 to the extreme position, the impurity removal part 212 still passes through and cooperates with the guiding member 22 and is located above the discharge port 13.

[0047] Preferably, the density of the material used to make the impurity removal hopper 21 is less than the density of fish oil, that is, the impurity removal hopper 21 will be subject to buoyancy in fish oil. After the fish oil is placed in the cavity 11, the whole impurity removal hopper 21 is immersed in the fish oil, and the impurity removal hopper 21 will remain in the state of the extreme position away from the discharge port 13 under the action of buoyancy.

[0048] A number of connecting members 23 are all fixedly installed on the guiding part 211. A number of installation openings 2111 adapted to the connecting members 23 are provided on the guiding part 211. The a number of installation openings 2111 are circumferentially arrayed on the guiding part 211 with the axis of the guiding part 211 as the center. After the connecting members 23 are installed on the guiding part 211, the corresponding installation openings 2111 are covered. A number of connecting holes 231 are provided on the connecting members 23, and the aperture of the connecting holes 231 is smaller than the particle size of the impurities in the fish oil, that is, the fish oil can pass through the connecting holes 231 and the impurities cannot pass through the connecting holes 231.

[0049] After the impurity removal hopper 21 is installed in the cavity 11, the space between the circumferential side of the impurity removal hopper 21 and the cavity wall of the cavity 11 communicates with the space between the upper part of the impurity removal hopper 21 and the cavity wall of the cavity 11 through a number of connecting holes 231 on a number of connecting members 23.

[0050] During the process of the precipitation and separation of impurities in the fish oil, the impurities will directly fall into the interior of the impurity removal part 212 or enter the interior of the impurity removal part 212 along the inner surface of the guiding part 211. When the content of impurities in the fish oil is small, that is, all the impurities can enter the interior of the impurity removal part 212, at this time, the impurities will be concentrated and piled up in the space above the valve 16. When the valve 16 is opened to control the discharge of impurities, the impurities can be discharged quickly and completely; when the content of impurities in the fish oil is large, that is, after the interior of the impurity removal part 212 is filled with impurities, there are still some impurities located inside the guiding part 211. At this time, the impurities located inside the guiding part 211 will exert a vertically downward force on the guiding part 211 under the action of their own gravity, thereby driving the impurity removal hopper 21 to slide downward. During the downward sliding process of the impurity removal hopper 21, the volume of the space between the circumferential side of the impurity removal hopper 21 and the cavity wall of the cavity 11 decreases, and the fish oil therein will pass through a number of connecting holes 231 of a number of connecting members 23 through the guiding part 211, thereby reducing the adhesion of impurities to the inner surface of the guiding part 211. When the valve 16 is opened to control the discharge of impurities, it helps the impurities to be discharged quickly and completely.

[0051] Further, the fish oil sedimentation tank further includes a plurality of third elastic members 5. The plurality of third elastic members 5 are located in the cavity 11 and installed on the tank body 1. The plurality of third elastic members 5 are all located below the edge of the flared end of the guiding portion 211. One end of the third elastic member 5 is fixedly connected to the edge of the flared end of the guiding portion 211 and the other end is fixedly connected to the tank body 1, and the plurality of third elastic members 5 are arranged in a circumferential array with the axis of the tank body 1 as the axis. Preferably, the third elastic member 5 is a compression spring, and the third elastic member 5 can drive the impurity discharging hopper 21 to slide to the limit position away from the discharge port 13 and maintain the position.

[0052] Further, the impurity discharging device 2 further includes a material blocking member 24, a shielding member 25, a support frame 26 and a sleeve 27. Among them, the material blocking member 24 is a circular plate-like structure as a whole. The material blocking member 24 is located inside the guiding portion 211. The periphery of the material blocking member 24 is in contact with and fixedly connected to the inner surface of the guiding portion 211, and at this time, the axis of the material blocking member 24 coincides with the axis of the guiding portion 211; a plurality of material passing holes 241 for impurities to pass through are formed in the material blocking member 24, and the plurality of material passing holes 241 are arranged in a circumferential array on the material blocking member 24 with the axis of the material blocking member 24 as the axis.

[0053] The shielding member 25 is also a circular plate-like structure as a whole. The shielding member 25 is located on the side of the material blocking member 24 close to the discharge port 13. The axis of the shielding member 25 coincides with the axis of the material blocking member 24, and the periphery of the shielding member 25 is also in contact with the inner surface of the guiding portion 211; the shielding member 25 is rotatably connected to the material blocking member 24, and the rotation axis of the shielding member 25 coincides with its own axis; a plurality of material leakage holes 251 are formed in the shielding member 25, the aperture of the material leakage holes 251 is equal to the aperture of the material passing holes 241, and the plurality of material leakage holes 251 are arranged in a circumferential array on the shielding member 25 with the axis of the shielding member 25 as the axis.

[0054] The support frame 26 is horizontally located inside the guiding member 22 near the discharge port 13, and the support frame 26 is fixedly connected to the guiding member 22. The sleeve 27 is a cylindrical structure as a whole. The sleeve 27 is fixedly installed at the central position of the support frame 26 in a vertical state. The sleeve 27 is located above the discharge port 13, and the axis of the sleeve 27 coincides with the axis of the discharge port 13.

[0055] An extension 252 extends from the shielding member 25 along its rotational axis toward the discharge port 13. The extension 252 is threadedly engaged with the sleeve 27 (since threaded engagement is a common method of engagement, the relevant structure of the threaded engagement is omitted in the accompanying drawings for ease of illustration). The extension 252 maintains its engagement with the sleeve 27 during the sliding movement of the debris bucket 21. As the debris bucket 21 slides, it drives the extension 252 of the shielding member 25 to move relative to the sleeve 27. As the extension 252 moves relative to the sleeve 27, it simultaneously moves relative to the sleeve 27 in the extension direction and rotates relative to the sleeve 27 about the axis of the sleeve 27, thereby driving the shielding member 25 to rotate relative to the material retaining member 24.

[0056] The plurality of through holes 241 correspond one-to-one with the plurality of leakage holes 251, i.e., the number of through holes 241 on the material stopper 24 is equal to the number of leakage holes 251 on the shielding member 25. When the hopper 21 slides to its limit position away from the discharge port 13, the plurality of through holes 241 and the plurality of leakage holes 251 are vertically staggered. At this point, after the hopper 21 slides a distance toward the discharge port 13, the shielding member 25 rotates relative to the material stopper 24, causing the plurality of through holes 241 to communicate with the corresponding leakage holes 251. As the shielding member 25 rotates relative to the material stopper 24, the area of communication between the through holes 241 and the leakage holes 251 gradually increases.

[0057] During the precipitation of impurities in the fish oil, the impurities will fall onto the material blocking member 24 along the guide portion 211. When the impurities on the material blocking member 24 reach a certain amount, the gravity of the impurities will drive the debris bucket 21 to slide downward; during the downward sliding of the debris bucket 21, the shielding member 25 will rotate relative to the material blocking member 24, so that the several through holes 241 are connected with the corresponding leakage holes 251, so that the impurities located above the material blocking member 24 can successively pass through the through holes 241 and the leakage holes 251 into the interior of the debris discharge portion 212; in addition, during the downward sliding of the debris bucket 21, the fish oil inside the debris bucket 21 and below the covering member will successively pass through the leakage holes 251 and the through hole 241 to the top of the material blocking member 24, thereby clearing the leakage holes 251 and the through hole 241, reducing the probability of the two being blocked by impurities.

[0058] Furthermore, it is preferred that the support frame 26 has a limiting effect on the sliding of the debris bucket 21 toward the discharge port 13, that is, when the debris bucket 21 slides toward the discharge port 13 to the extreme position, the end of the debris discharge portion 212 away from the guide portion 211 is against the support frame 26, and at this time the discharge hole and the corresponding leakage hole 251 are aligned in the vertical direction, that is, the degree of communication between the two is the greatest.

[0059] Furthermore, the support frame 26 includes a plurality of support members 261, all of which are in a horizontal state. One end of the support member 261 is fixedly connected to the inner surface of the guide member 22, and the other end of the support member 261 is fixedly connected to the outer surface of the sleeve 27. The plurality of support members 261 are distributed in a circular array around the sleeve 27 with the axis of the sleeve 27 as the axis.

[0060] Through holes for impurities to pass through are formed between adjacent support members 261. Impurities will pass through the plurality of through holes from the interior of the impurity discharge portion 212 and then leave the cavity 11 through the discharge port 13. When the impurities are discharged, they can be divided into several streams and discharged, thereby improving the discharge efficiency.

[0061] Furthermore, both ends of the end face of the support member 261 facing away from the discharge port 13 have inclined surfaces 2611, and the end of the inclined surface 2611 close to the adjacent support member 261 is the inclined lower end. After impurities fall onto the support member 261, they can move toward the through port along the inclined surface 2611, thereby reducing the probability of impurities adhering to the support member 261.

[0062] Furthermore, it is preferred that the position where the several connecting parts 23 are installed on the guide part 211 is located on the side of the blocking part 24 away from the shielding part 25, that is, the space between the peripheral side of the discharge bucket 21 and the wall of the cavity 11 can only be communicated with the space between the top of the blocking part 24 and the wall of the cavity 11 through the several connecting holes 231 on the several connecting parts 23.

The first vibration assembly 3 includes a first vibrating member 31 and a first elastic member 32. The first vibrating member 31 is slidably connected to the shielding member 25, and the sliding direction of the first vibrating member 31 is perpendicular to the guide portion 211. The first elastic member 32 is installed inside the shielding member 25 and is located on the side of the first vibrating member 31 close to the center of the shielding member 25. The two ends of the first elastic member 32 respectively abut against the first vibrating member 31 and the shielding member 25, and the first elastic member 32 drives the first vibrating member 31 to slide in the direction close to the guide portion 211. The sliding process of the first vibrating member 31 is limited. When the first vibrating member 31 slides to the extreme position in the direction close to the guide portion 211, the end of the first vibrating member 31 away from the first elastic member 32 will extend out of the peripheral side of the shielding member 25. When the first vibrating member 31 slides to the extreme position in the direction away from the guide portion 211, the first vibrating member 31 will be completely retracted into the interior of the shielding member 25.

[0064] Preferably, the first vibrating member 31 is integrally spherical, and a plurality of first fitting grooves 2112 adapted to the first vibrating member 31 are formed on the inner surface of the guiding portion 211. When the first vibrating member 31 is aligned with the first fitting grooves 2112 along its sliding direction, the first vibrating member 31 will slide under the action of the first elastic member 32 and be inserted into the first fitting grooves 2112 in a plug-in fit. During the process of the first vibrating member 31 sliding and inserting into the first fitting grooves 2112, the first vibrating member 31 will impact the groove walls of the first fitting grooves 2112, causing the guiding portion 211 to vibrate. In this embodiment, it is preferred that the first vibrating assembly 3 is a ball screw. Since the ball screw is a common prior art, it will not be elaborated here.

When the impurity discharging hopper 21 slides in the direction away from the discharge port 13 to the extreme position, the first vibrating member 31 is inserted into the corresponding first fitting groove 2112 under the action of the first elastic member 32; at this time, during the process of the impurity discharging hopper 21 sliding in the direction close to the discharge port 13 to the extreme position, the first vibrating member 31 will slide and expand and contract multiple times under the action of the first elastic member 32 and the limitation of the groove walls of the first fitting grooves 2112, and be inserted into the plurality of first fitting grooves 2112 in sequence, that is, it can impact the guiding portion 211 multiple times to cause the guiding portion 211 to vibrate multiple times, thereby reducing the probability of impurities adhering to the inner surface of the guiding portion 211.

[0066] Refer to Figure 2 and Figure 5 A plurality of second vibrating assemblies 4 are all installed on the guiding member 22, and the installation positions of the plurality of second vibrating assemblies 4 on the guiding member 22 are distributed in a circumferential array with the axis of the guiding member 22 as the axis.

The two ends of the second elastic member 42 are respectively abutted against the second vibrating member 41 and the guiding member 22, and the second elastic member 42 drives the second vibrating member 41 to slide in the direction close to the impurity discharging portion 212; there is a limitation during the sliding process of the second vibrating member 41. When the second vibrating member 41 slides in the direction close to the impurity discharging portion 212 to the extreme position, the end of the second vibrating member 41 away from the second elastic member 42 will extend out and be located inside the guiding member 22; when the second vibrating member 41 slides in the direction away from the impurity discharging portion 212 to the extreme position, the second vibrating member 41 will completely retract into the guiding member 22. In this embodiment, it is preferred that the second elastic member 42 is also a compression spring.

[0067] Preferably, the second vibrating member 41 is also integrally spherical, and a plurality of second fitting grooves 2121 adapted to the second vibrating member 41 are formed on the outer surface of the impurity discharging portion 212. When the second vibrating member 41 and the second fitting groove 2121 are aligned along their sliding directions, the second vibrating member 41 will slide and be inserted into the second fitting groove 2121 under the action of the second elastic member 42. During the process of the second vibrating member 41 sliding and inserting into the second fitting groove 2121, the second vibrating member 41 will impact the groove wall of the second fitting groove 2121, causing the impurity discharging portion 212 to vibrate. In this embodiment, it is preferred that the second vibrating assembly 4 is also a ball screw. Since the ball screw is a common prior art, it will not be elaborated here.

[0068] One second vibrating member 41 corresponds to a plurality of second fitting grooves 2121, and the plurality of second fitting grooves 2121 are distributed on the outer surface of the impurity discharging portion 212 along the axial direction of the impurity discharging portion 212.

[0069] The implementation principle of an oil fish precipitation tank facilitating impurity discharge in an embodiment of the present application is as follows:

[0070] The impurities precipitated after the oil fish precipitation will fall onto the baffle member 24 under the guidance of the guiding portion 211. When the impurities on the baffle member 24 reach a certain amount, the impurities will drive the impurity discharging hopper 21 to slide downward; during the process of the impurity discharging hopper 21 sliding downward, the shielding member 25 will rotate relative to the baffle member 24, so that the impurities on the baffle member 24 can pass through the material passing hole 241 and the leakage hole 251 in sequence and fall into the interior of the impurity discharging portion 212 and accumulate in the space around the discharge port 13, thereby facilitating the discharge of impurities, improving the effect of impurity discharge, and at the same time reducing the discharge of oil fish along with the impurities;

[0071] During the process of the impurity discharging hopper 21 sliding downward, a plurality of first vibrating assemblies 3 and a plurality of second vibrating assemblies 4 will be triggered, so that both the guiding portion 211 and the impurity discharging portion 212 are impacted and vibrated, thereby reducing the probability of impurities adhering to the guiding portion 211 and the impurity discharging portion 212.

[0072] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
