Description

Technical Field

[0001] This invention relates to the field of aquatic product processing waste treatment technology, and in particular to a vortex-type solid-liquid separation device and separation method for aquatic product processing waste. Background Technology

[0002] During aquatic product processing, a large amount of waste containing solid components such as fish scales, viscera, meat scraps, and bone fragments is generated. This waste usually exists in the form of a solid-liquid mixture with high water content. In order to achieve resource utilization and environmentally friendly emissions, this type of waste needs to be effectively separated into solid and liquid phases. At present, hydrocyclones are widely used in industry as the core equipment for preliminary separation. Hydrocyclones use centrifugal force fields to accelerate the sedimentation and separation of solid and liquid phases: after the solid-liquid mixture enters the hydrocyclone cylinder through the tangential feed inlet, under the action of the high-speed rotating flow field, the denser solid particles are thrown against the cylinder wall and move downward along the conical section, and finally discharged from the bottom sedimentation port; while the clarified liquid flows upward and is discharged through the top overflow pipe, thus completing the solid-liquid separation.

[0003] However, existing hydrocyclones still have significant technical limitations in practical applications. The most prominent problem lies in the lack of flexibility in the design of their feed structure. The feed pipes of traditional hydrocyclones are usually fixed and mostly arranged horizontally. While this structure is suitable for processing materials within a specific concentration range, it is difficult to adapt to different working conditions when dealing with complex solid-liquid mixtures of waste generated during aquatic product processing, which have large concentration fluctuations, significant viscosity changes, and uneven particle size distribution. For example, when the material concentration is too high, horizontal feeding can easily lead to increased feed resistance, poor flow, or even blockage. When the material is relatively thin, horizontal feeding may result in insufficient tangential velocity, weakening the swirling effect and reducing separation efficiency. Summary of the Invention

[0004] In view of this, the present invention provides a vortex-type solid-liquid separation device and separation method for aquatic processing waste, which can solve the shortcomings of existing hydrocyclones, which are usually fixed in installation and mostly arranged horizontally, making it difficult to adapt to the requirements of materials with different concentrations.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A vortex-type solid-liquid separation device for aquatic processing waste includes a support platform, a separation cylinder, a feed pipe, an overflow pipe, a first motor, a rotating frame, a belt drive, a discharge pipe, a hose, a filter cylinder, a drainage mechanism, a collection mechanism, and a compression mechanism. The separation cylinder is mounted on the support platform. The feed pipe is mounted on the side of the separation cylinder, and the overflow pipe is mounted on the top of the separation cylinder. The first motor is mounted on the separation cylinder. A belt drive is installed between the output shaft of the first motor and the rotating frame for transmission between the output shaft of the first motor and the rotating frame. The discharge pipe is mounted on the power output shaft of the rotating frame and its tilt angle and spray direction are flexibly adjusted by the power output shaft of the rotating frame. The outlet of the feed pipe is connected to one end of the hose, and the other end of the hose is connected to the inlet end of the discharge pipe. The outlet end of the discharge pipe communicates with the inside of the separation cylinder. A filter cylinder is mounted at the bottom of the separation cylinder. The filter cylinder is equipped with a drainage mechanism for discharging liquid, a compression mechanism for compressing solids, and a collection mechanism for collecting the compressed solids.

[0006] Preferably, the drainage mechanism includes a sleeve and a drain pipe, with the sleeve installed outside the filter cartridge and the drain pipe connected to the sleeve for discharging liquid.

[0007] Preferably, the collection mechanism includes a collection cylinder, a cross, a sealing cap, and a first spring. The bottom of the sleeve is equipped with a collection cylinder for collecting solids. The cross is installed inside the collection cylinder. A sealing cap for sealing the bottom of the filter cylinder is slidably disposed on the cross. The sealing cap and the cross are connected by a first spring.

[0008] Preferably, the compression mechanism includes a bracket, a second motor, a connecting shaft, and helical blades. The bracket is installed inside the filter cartridge, and the second motor is installed on the bracket. The output shaft of the second motor is vertically downward and connected to the connecting shaft, which is vertically arranged inside the filter cartridge. Helical blades for compressing solids are installed on the connecting shaft.

[0009] Preferably, the vortex-type solid-liquid separation device for aquatic processing waste further includes a flow guiding mechanism, which includes a rotating shaft and a flow guiding plate. The rotating shaft is rotatably mounted on the separation cylinder at intervals, and the flow guiding plate is connected to the rotating shaft for guiding the flow of materials.

[0010] Preferably, the vortex-type solid-liquid separation device for aquatic processing waste further includes a self-adjusting mechanism. The self-adjusting mechanism includes a fixed frame, an annular frame, toothed blocks, a first gear, and a second gear. Multiple vertically arranged fixed frames are installed at intervals on the outer side of the separation cylinder in the circumferential direction. The annular frame is sleeved on the outside of the separation cylinder and slides in cooperation with the fixed frames. Multiple toothed blocks are arranged at intervals on the annular frame. The first gear is connected to the rotating shaft, and the second gear is connected to the output shaft of the first motor. Both the first gear and the second gear mesh with the toothed blocks on the corresponding sides.

[0011] Preferably, the vortex-type solid-liquid separation device for aquatic processing waste further includes a striking mechanism. The striking mechanism includes a guide rail frame, a sliding frame, a striking frame, a second spring, a vibration motor, and an electric wheel. The guide rail frame is fitted over the separation cylinder and located below the annular frame. The sliding frame is slidably mounted on the guide rail frame. A striking frame for striking the separation cylinder is provided between the sliding frame and the separation cylinder. A second spring connects the striking frame and the sliding frame. A vibration motor is mounted on the striking frame. Electric wheels are rotatably mounted on both the upper and lower parts of the sliding frame. The electric wheels are used to drive the sliding frame to slide along the guide rail frame.

[0012] This invention also provides a vortex-type solid-liquid separation method for aquatic processing waste. This method employs the aforementioned vortex-type solid-liquid separation device for aquatic processing waste and includes the following steps: First, a rotating frame is driven to rotate via a first motor and a belt drive component, thereby adjusting the inclination angle and orientation of the discharge pipe; next, material is fed in through the feed pipe, allowing it to enter the separation cylinder through a hose and discharge pipe for high-speed rotation, thus forming a vortex flow and achieving solid-liquid separation; subsequently, the liquid in the filter cylinder is discharged through a drainage mechanism; next, the solids in the filter cylinder are compacted through a compression mechanism, and the compacted solids are sent to a collection mechanism for collection; finally, the solids in the collection mechanism are cleaned.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, by setting up an adjustable feeding structure consisting of a rotating frame driven by a first motor, a discharge pipe, and a hose, can flexibly adjust the tilt angle and spray direction of the discharge pipe according to the concentration, viscosity, and particle characteristics of aquatic processing waste. This design effectively solves the problem of blockage of high-concentration materials or insufficient swirling of low-concentration materials caused by fixed horizontal feeding in traditional hydrocyclones, and significantly improves the device's adaptability to complex and fluctuating operating conditions.

[0014] 2. The present invention provides a spiral blade compression mechanism driven by a second motor inside the filter cartridge. The blade spacing gradually decreases from top to bottom. While conveying the solid, it applies progressive pressure to effectively squeeze out the residual water in the solid. The moisture content of the compressed solid is significantly reduced, which facilitates subsequent resource utilization or harmless treatment.

[0015] 3. The striking mechanism of the present invention drives the striking frame to move around the separation cylinder through an electric wheel, and generates high-frequency striking vibration in combination with a vibration motor, which effectively removes fine solids (such as particles or fish scales) attached to the inner wall of the separation cylinder, prevents scaling and clogging, ensures stable operation of the device for a long time, and reduces the frequency of manual maintenance.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] See Figures 1-6 As shown, a vortex-type solid-liquid separation device for aquatic processing waste includes a support platform 1, a separation cylinder 2, a feed pipe 3, an overflow pipe 4, a first motor 5, a rotating frame 6, a belt drive component 7, a discharge pipe 8, a hose 9, a filter cartridge 10, a drainage mechanism, a collection mechanism, and a compression mechanism. The separation cylinder 2 is installed on the upper side of the support platform 1. The separation cylinder 2 is divided into upper and lower parts. The upper part is a straight cylindrical structure, which is the initial area for vortex formation, where the material begins to rotate at high speed. The lower part is an inverted conical structure; as the diameter gradually decreases, the rotational speed increases, and the centrifugal force is enhanced, which is beneficial for solid-liquid separation. The feed pipe 3 is installed on the upper right front side of the separation cylinder 2. The feed pipe 3 is located tangentially to the upper straight cylindrical structure of the separation cylinder 2, allowing the material to enter the separation cylinder 2 tangentially at a certain pressure, forming a swirling flow. An overflow pipe 4 is installed at the top of the separation cylinder 2, which is used to discharge liquid from the material (refer to the working principle of hydrocyclones in the prior art for details).

[0029] A first motor 5 is installed on the upper front side of the separating cylinder 2, and a rotating frame 6 is rotatably installed on the left side of the feed pipe 3. A belt drive 7 includes a synchronous pulley and a synchronous belt. The output shaft of the first motor 5 is connected to synchronous pulleys on the front side of the rotating frame 6 (i.e., the power input end of the rotating frame 6), and a synchronous belt is wound between the two synchronous pulleys. The output shaft of the first motor 5 drives the rotating frame 6 to rotate through the synchronous pulleys and the synchronous belt. The belt drive 7 is used for transmission between the output shaft of the first motor 5 and the rotating frame 6. The discharge pipe 8 is mounted on the power output shaft of the rotating frame 6 and its tilt angle and spray direction are flexibly adjusted by the power output shaft of the rotating frame 6. The outlet of the feed pipe 3 is connected to one end of a hose 9, and the other end of the hose 9 is connected to the inlet end of the discharge pipe 8. The outlet end of the discharge pipe 8 communicates with the inside of the separating cylinder 2, and the hose 9 is used to allow the material in the feed pipe 3 to flow into the discharge pipe 8. A filter cartridge 10 is installed at the bottom of the separator 2. The filter cartridge 10 is equipped with a drainage mechanism for discharging liquid. The filter cartridge 10 is also equipped with a compression mechanism for compressing solids and a collection mechanism for collecting the compressed solids.

[0030] See Figure 3 and Figure 4 As shown, the drainage mechanism includes a sleeve 1101 and a drain pipe 1102. The sleeve 1101 is installed on the outside of the filter cartridge 10. The top end of the sleeve 1101 is sealed to the outer wall of the filter cartridge 10, and the bottom end of the sleeve 1101 is also sealed to the outer wall of the filter cartridge 10. A partition is provided between the inner wall of the sleeve 1101 and the outer wall of the filter cartridge 10. The lower left side of the sleeve 1101 is connected to the drain pipe 1102 for draining liquid.

[0031] See Figures 3-6As shown, the collection mechanism includes a collection cylinder 1201, a crossbeam 1202, a sealing cap 1203, and a first spring 1204. The collection cylinder 1201 for collecting solids is installed at the bottom of the sleeve 1101. A baffle is detachably installed on the lower front side of the collection cylinder 1201, allowing the operator to easily clean solid debris from the collection cylinder 1201 by opening the baffle. A crossbeam 1202 is installed inside the collection cylinder 1201. The crossbeam 1202 is horizontally positioned, and all four corners of the crossbeam 1202 are fixedly connected to the inner wall of the collection cylinder 1201. A sealing cap 1203 is slidably mounted on the cross 1202. In this embodiment, a vertical guide rod is provided in the middle of the cross 1202. The sealing cap 1203 is sleeved on the guide rod and slides vertically with the guide rod. The sealing cap 1203 is used to seal the bottom of the filter cartridge 10 to prevent solid and liquid from flowing directly into the collection cartridge 1201 without compression. The bottom of the sealing cap 1203 is conical, which facilitates the sliding of solids. A first spring 1204 is connected between the bottom of the sealing cap 1203 and the top of the cross 1202. The first spring 1204 is sleeved on the guide rod. On the rod, the top of the first spring 1204 presses against the bottom of the sealing cover 1203, and the bottom of the first spring 1204 presses against the cross 1202. Under the upward pre-pressure of the first spring 1204, the sealing cover 1203 is pushed upward to seal the bottom outlet of the filter cartridge 10. When the compressed solid in the filter cartridge 10 reaches a certain amount, under the downward push of the spiral blade 1304, the compressed solid is driven to press the sealing cover 1203 downward, and the sealing cover 1203 is driven to move downward. The compressed solid slides through the inner conical surface of the sealing cover 1203 into the collection cylinder 1201.

[0032] See Figure 5 and Figure 6 As shown, the compression mechanism includes a support 1301, a second motor 1302, a connecting shaft 1303, and spiral blades 1304. The support 1301 is mounted on the upper side of the filter cartridge 10, with its end fixedly connected to the inner wall of the filter cartridge 10. The second motor 1302 is mounted in the middle of the top of the support 1301, and its output shaft vertically downwards through the middle of the support 1301 and rotatably engages with it. The bottom end of the output shaft of the second motor 1302 is connected to the connecting shaft 1303, which is vertically positioned inside the filter cartridge 10. Spiral blades 1304 for compressing solids are mounted on the connecting shaft 1303. The spacing between the spiral blades 1304 gradually decreases from top to bottom, gradually increasing the compressive pressure on the solids during downward transport, thereby compacting the solids at the bottom and reducing the water content in the solids.

[0033] A vortex-type solid-liquid separation method for aquatic product processing waste, comprising the following steps: First, based on the particulate matter concentration of the material, the first motor 5 drives the rotating frame 6 to rotate via the belt drive 7, thereby rotating the discharge pipe 8. This adjusts the tilt angle and orientation of the discharge pipe 8, adapting its discharge angle to different material concentrations. (For high-concentration, high-viscosity, and easily clogged materials, the tilt angle is increased, making the discharge pipe 8 closer to vertical downwards, thus reducing feeding resistance, utilizing gravity-assisted feeding, avoiding backflow or accumulation caused by horizontal or upward spraying, and reducing excessive reliance on the initial kinetic energy of the vortex, effectively preventing inlet blockage, ensuring continuous and stable feeding, and maintaining basic vortex intensity. For low-concentration, dilute materials, the tilt angle is decreased, making the discharge pipe 8 closer to the horizontal tangential direction, thus maximizing the tangential velocity component and enhancing the initial rotation.) Kinetic energy forms a strong centrifugal field, avoiding ineffective solid-liquid separation due to insufficient flow rate, thereby increasing the swirling intensity, improving the collection efficiency of fine particles, and preventing material from flowing directly to the bottom. After adjustment, the material is fed in through the feed pipe 3, entering the hose 9, and then flowing into the discharge pipe 8. The discharge pipe 8 discharges the material at a certain angle into the separation cylinder 2, causing the material to rotate at high speed in the separation cylinder 2, gradually forming a swirling flow. During the high-speed rotation of the material, due to centrifugal force, the solids in the material are thrown towards the inner wall of the separation cylinder 2 and discharged downward from the separation cylinder 2 into the filter cylinder 10 with the outer swirling flow, while a portion of the liquid in the material forms an inner swirling flow and is discharged upward from the overflow pipe 4, thereby achieving solid-liquid separation of the material.

[0034] When the solids in the material are discharged into the filter cartridge 10 by the outer swirling flow, the filter cartridge 10 filters the solids and the remaining liquid in the material. The remaining liquid passes through the filter cartridge 10 into the partition of the sleeve 1101 and is discharged through the drain pipe 1102, while the solids in the material remain in the filter cartridge 10 and fall onto the spiral blades 1304. Then, the second motor 1302 is started to drive the connecting shaft 1303 and the spiral blades 1304 to rotate, causing the spiral blades 1304 to convey the solids in the material downwards. As the spacing between the blades of the spiral blades 1304 gradually decreases from top to bottom, the compression pressure on the solids gradually increases during the downward conveying process, thereby compacting the solids on the lower side and forcing out the residual liquid in the solids. After the compacted solid leaves the spiral blade 1304 via the conveyor, it falls onto the conical surface of the sealing cover 1203. When the weight of the solid accumulated on the conical surface and the downward squeezing force exerted by the spiral blade 1304 on the bottom solid are sufficient to overcome the elastic force of the first spring 1204, the solid will squeeze the sealing cover 1203 downward, thereby opening the bottom outlet of the filter cartridge 10. The first spring 1204 is compressed, and then the solid will slide down the conical surface into the collection cylinder 1201 for collection. When the solid on the conical surface is insufficient to overcome the elastic force of the first spring 1204, the first spring 1204 returns to its original state and drives the sealing cover 1203 to move upward and close, preventing the solid and liquid from flowing directly into the collection cylinder 1201 without compression.

[0035] After the material has completed solid-liquid separation, turn off the second motor 1302 to stop the connecting shaft 1303 and the spiral blades 1304 from rotating, and finally clean the solid in the collection cylinder 1201.

[0036] See Figure 7 and Figure 8 As shown, the vortex-type solid-liquid separation device for aquatic processing waste also includes a flow guiding mechanism, which includes a rotating shaft 14 and a flow guiding plate 15. Four rotating shafts 14 are rotatably installed at intervals on the wall of the separation cylinder 2, and the heights of the four rotating shafts 14 are different. The end of the rotating shaft 14 facing the inside of the separation cylinder 2 is connected to the flow guiding plate 15, which is used to guide the flow of materials.

[0037] See Figure 7 and Figure 8As shown, the vortex-type solid-liquid separation device for aquatic processing waste also includes a self-adjusting mechanism, which comprises a fixed frame 16, an annular frame 17, toothed blocks 18, a first gear 19, and a second gear 20. Four vertically arranged fixed frames 16 are installed at intervals along the circumference of the outer surface of the separation cylinder 2; the annular frame 17 is fitted around the separation cylinder 2 and slides in cooperation with the four fixed frames 16. Toothed blocks 18 are spaced apart on the annular frame 17 near the rotating shaft 14 and the first motor 5; the first gear 19 is connected to the end of the rotating shaft 14 facing the outside of the separation cylinder 2; the second gear 20 is connected to the output shaft of the first motor 5, and both the first gear 19 and the second gear 20 mesh with the toothed blocks 18 on their corresponding sides. In this embodiment, the rotating shaft 14 is mounted on the inner wall of the separation cylinder 2 through a bearing support seat and is rotatably connected to the bearing support seat. The rotating shaft 14 passes through the separation cylinder 2 and rotates with the separation cylinder 2 and is sealed. Each rotating shaft 14 is equipped with a guide plate 15 at the end inside the separation cylinder 2 and a first gear 19 at the end outside the separation cylinder 2.

[0038] This invention, by setting up a flow guiding mechanism and a self-adjusting mechanism, allows the first motor 5's output shaft to drive the rotating frame 6 to rotate via the belt drive 7. This, in turn, drives the second gear 20 to rotate, which in turn drives the ring frame 17 to rotate via the corresponding tooth block 18. This, in turn, drives the first gear 19 and the rotating shaft 14 to rotate via the tooth block 18, which in turn drives the flow guide plate 15 to rotate. Thus, when adjusting the tilt angle and orientation of the discharge pipe 8, the tilt state and orientation of the flow guide plate 15 are simultaneously and automatically adjusted. When material enters the separation cylinder 2 and contacts the flow guide plate 15, the flow guide plate 15 guides the material to rotate at high speed, thereby guiding the material and thus the direction and stability of the swirling flow. Especially under non-ideal inflow conditions (such as angle deviation and flow fluctuation), it plays a "rectifying" role, effectively constraining the fluid path, quickly establishing a stable swirling flow, and reducing energy loss.

[0039] See Figure 9 and Figure 10As shown, the vortex-type solid-liquid separation device for aquatic processing waste also includes a striking mechanism, which comprises a guide rail frame 21, a sliding frame 22, a striking frame 23, a second spring 24, a vibration motor 25, and an electric wheel 26. The guide rail frame 21 is installed on the lower outer side of the separation cylinder 2, and the guide rail frame 21 is fitted around the separation cylinder 2 and located below the annular frame 17. A sliding frame 22 is slidably mounted on the guide rail frame 21. In this embodiment, electric wheels 26 are rotatably mounted on both the upper and lower parts of the sliding frame 22. The electric wheels 26 contact the guide rail frame 21, and the sliding frame 22 slides along the guide rail frame 21 driven by the electric wheels 26. A striking frame 23 is provided on the side of the sliding frame 22 near the outer wall of the separation cylinder 2. The striking frame 23 is used to strike the outer wall of the separation cylinder 2. Two second springs 24 are connected between the side of the striking frame 23 away from the outer wall of the separation cylinder 2 and the sliding frame 22. One second spring 24 is located in the upper part of the sliding frame 22, and the other second spring 24 is located in the lower part of the sliding frame 22. Two vibration motors 25 are installed on the striking frame 23 near the upper part and near the lower part.

[0040] When using this striking mechanism, the electric wheel 26 can be activated to drive the sliding frame 22 to slide along the guide rail 21, causing the sliding frame 22 to drive the striking frame 23 to rotate around the separation cylinder 2. At the same time, the vibration motor 25 is activated, causing the vibration motor 25 to drive the striking frame 23 to reciprocate on the sliding frame 22. The second spring 24 deforms adaptively, causing the striking frame 23 to periodically strike the outer wall of the separation cylinder 2, thereby causing the outer wall of the separation cylinder 2 to vibrate and shake off the solids (such as particles or fish scales) adhering to the inner wall of the separation cylinder 2, preventing solids from adhering to the inner wall of the separation cylinder 2 and causing residue. After the material has completed solid-liquid separation, the electric wheel 26 and the vibration motor 25 can be turned off.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
