Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of aquatic processing, and particularly relates to a squid cleaning device based on ultrasonic waves and a use method thereof. BACKGROUND

[0002] Squid, i.e., Chinese common squid, is a marine cephalopod mollusk of the order of Todarida and the family of Todaridae, and the body of the squid is long and slender, and the squid is named after the common squid because the shape is similar to the common squid, i.e., cuttlefish, but the body of the squid is longer than that of the common squid, the abdomen is cylindrical, is pale, and has light brown spots on the body, the tail end is rhombic, the head has eight soft feet, two long tentacles, and a suction cup. The squid cleaning device is a cleaning device for processing dried squid, and the main processing process is to cut off the internal organs of fresh squid, then clean and drain the fresh squid, and finally process the fresh squid into dried squid products.

[0003] However, although the traditional mechanical brush cleaning of the squid cleaning device can remove surface impurities, it is difficult to decompose the biological mucus layer, and an additional power-driven stirring mechanism is required, which has high energy consumption. Pure water pressure washing will cause waste of water resources, and at the same time, the passive dehydration method depending on natural draining or simple extrusion will cause serious retention of water in the squid tissue, which will prolong the production cycle.

[0004] In order to solve the problems mentioned in the above background, a squid cleaning device based on ultrasonic waves is provided. SUMMARY

[0005] The purpose of the present application is to provide a squid cleaning device based on ultrasonic waves and a use method thereof, which has the advantages of saving energy consumption and accelerating draining.

[0006] The above technical purpose of the present application is achieved by the following technical scheme:

[0007] A squid cleaning device based on ultrasonic waves comprises a base, an outer shell is arranged on the base in an inclined manner, a feed pipe is arranged at the top of the left side of the outer shell, and a filter cartridge is rotatably arranged in the outer shell;

[0008] A groove is formed in the left side of the inner part of the outer shell, a rotating rod is rotatably connected between the bottom of the groove and the right side of the inner part of the outer shell, the rotating rod penetrates the filter cartridge, and a plurality of stirring rods are welded on the surface of the rotating rod along the length direction;

[0009] A impeller is arranged on the rotating rod in the groove, a water inlet pipe is connected to the left side of the outer shell and communicates with the groove, a discharge pipe with a valve is connected to the bottom of the right side of the outer shell and penetrates the bottom of the outer shell, and a plurality of ultrasonic devices are embedded in the bottom of the outer shell;

[0010] A shaking mechanism is arranged on the base to the right of the discharge pipe.

[0011] The above technical solution involves the following steps: the squid to be cleaned enters the filter cylinder through the feed pipe, and water is added to the shell. The water flows in through the inlet pipe, impacting the impeller in the groove, which in turn drives the impeller and the rotating rod to rotate synchronously. The stirring rod on the rotating rod also rotates, continuously stirring the squid in the filter cylinder to improve the cleaning effect. During this process, the ultrasonic device at the bottom of the shell is activated, which can efficiently break down the mucus and residual impurities on the surface. In addition, as the cleaning process proceeds, the water containing impurities can seep out through the mesh of the filter cylinder and be discharged. After the cleaning is completed, the squid is discharged through the discharge pipe.

[0012] The present invention is further configured such that a gear ring is provided on the outer side of the left end of the filter cartridge, a second motor is provided inside the housing, and a gear is provided on the output shaft of the second motor, the gear and the gear ring being meshed and connected.

[0013] The above technical solution is adopted: the second motor drives the gear to rotate, and then the gear ring and filter cylinder rotate accordingly. The rotation of the filter cylinder will also drive the surrounding water to form a ring vortex. The vortex and the centrifugal force of the filter cylinder work together to make the surface of the squid fully contact the water, and achieve all-round cleaning in conjunction with the ultrasonic cavitation effect.

[0014] The present invention is further configured such that a plurality of spiral stirring blades are arranged on the rotating rod along the length direction, and scrapers are connected to the outer sides of the plurality of spiral stirring blades.

[0015] The above technical solution is adopted: the spiral stirring blades divide the internal space of the filter cylinder into a spiral shape. When it rotates, it continuously pushes the squid around the rotating rod outward in a spiral shape to avoid accumulation.

[0016] The present invention is further configured such that a fixing strip is provided along the length direction of the inner top of the outer shell, and a cleaning brush is provided on the side of the fixing strip near the filter cartridge.

[0017] The above technical solution is adopted so that when the filter cartridge rotates, the cleaning brush continuously cleans the outer surface of the filter cartridge to prevent impurities from clogging and affecting the normal discharge of sewage.

[0018] The present invention is further configured such that the shaking mechanism includes a filter box located at the bottom right side of the discharge pipe, a bracket is bolted to the back of the filter box, a rocker arm is hinged to the top and bottom of the inner wall of the bracket, a turntable is hinged to the rear end of the bottom of the rocker arm, a first motor is fixedly sleeved at the center of the bottom of the turntable, and a water filter box is embedded in the bottom of the first motor.

[0019] The present invention is further configured such that the shaking mechanism includes a filter box located at the bottom right side of the discharge pipe, a bracket is bolted to the back of the filter box, a rocker arm is hinged to the top and bottom of the inner wall of the bracket, a turntable is hinged to the rear end of the bottom of the rocker arm, a first motor is fixedly sleeved at the center of the bottom of the turntable, and a water filter box is embedded in the bottom of the first motor.

[0020] The above technical solution employs a shaking mechanism. After the squid cleaning process is completed, the cleaned squid enters the filter box through the discharge pipe. The first motor starts, driving the top turntable to rotate. As the turntable rotates, it pushes the rocker arm to reciprocate through the hinge point. The reciprocating motion of the rocker arm is directly transmitted to the connected filter box, causing it to vibrate continuously. This vibration causes the squid inside to continuously turn and shift, preventing local accumulation and allowing excess water adhering to the surface of the squid to detach under the vibration and be discharged into the bottom filter box. Furthermore, the inertial force generated by the vibration further removes fine impurities remaining on the surface of the squid, improving the cleanliness. After deep cleaning, efficient dehydration is achieved. The regular vibration breaks the surface tension of water through physical oscillation, shortening the dehydration time compared to the traditional static draining method. This significantly reduces the energy consumption cost of subsequent drying processes while improving the efficiency of aquatic product processing.

[0021] The present invention is further configured such that sliders are bolted to the front and rear ends of both sides of the filter box, and sliding grooves are provided on the front and rear ends of both sides inside the filter box, and the interior of the sliding grooves is slidably connected to the surface of the sliders.

[0022] The above technical solution uses sliders and grooves to limit the movement of the filter box and keep it stable.

[0023] The present invention is further configured such that a first drain pipe with a valve is connected to the bottom right side of the outer casing, and a second drain pipe with a valve is connected to the bottom of the filter box.

[0024] The above technical solution allows for the convenient drainage of water used to clean the squid inside the shell by setting up a first drain pipe, and the convenient drainage of water from the filter box by setting up a second drain pipe.

[0025] The method of using this invention is achieved through the following steps:

[0026] S1. The squid to be cleaned enters the filter cylinder through the feed pipe, and then water is released into the water inlet pipe. The water flow impacts the impeller, causing the impeller to rotate, which in turn drives the rotating rod and spiral stirring blades fixed to it to rotate synchronously. The stirring rod continuously stirs the squid, and the spiral stirring blades continuously push the squid around the rotating rod outward in a spiral motion to prevent accumulation.

[0027] S2. Simultaneously activate the ultrasonic device at the bottom of the shell. The high-frequency vibration generated by the device creates a large number of tiny bubbles in the water. These bubbles are continuously generated, grow and burst instantly under the action of ultrasonic waves. The huge impact force released when they burst directly acts on the surface and folds of the squid, which can effectively break down the mucus and residual impurities on the surface.

[0028] S3. Simultaneously start the second motor, which drives the gear ring and filter cylinder to rotate through the gear. The squid makes a projectile motion inside the filter cylinder, and its spatial position changes continuously with the circumferential motion of the filter cylinder. The rotation of the filter cylinder will also drive the surrounding water to form a ring vortex. The vortex and the centrifugal force of the filter cylinder work together to make the surface of the squid fully contact the water. Combined with the ultrasonic cavitation effect, it achieves all-round cleaning.

[0029] S4. Due to the rotation of the filter cartridge, the cleaning brush continuously cleans the impurities on the surface of the filter cartridge to prevent the filter cartridge from clogging. As the cleaning process proceeds, water containing impurities can seep out through the mesh of the filter cartridge and be discharged through the first drain pipe. After the cleaning is completed, the squid is discharged through the discharge pipe.

[0030] S5. After cleaning, the squid enters the filter box through the discharge pipe. The first motor is started, which drives the top turntable to rotate. When the turntable rotates, it pushes the rocker arm to swing back and forth through the hinge point, causing the filter box to vibrate continuously. The vibration of the filter box can cause the squid inside to turn and move continuously in the box, avoiding local accumulation. It also allows the excess water on the surface of the squid to be removed under the action of vibration and discharged into the bottom filter box.

[0031] In summary, the present invention has the following beneficial effects:

[0032] 1. This invention uses the force of water flow to drive the impeller, which in turn drives the rotating rod, stirring rod, and spiral stirring blade to rotate in coordination, causing the squid to tumble three-dimensionally inside the filter cartridge. Combined with the cavitation effect of the ultrasonic device to break down the surface mucus, and the eddy current generated by the rotation of the filter cartridge to physically remove impurities, the cleaning efficiency is significantly improved. Its self-driving design also saves energy consumption.

[0033] 2. This invention generates regular vibrations through a shaking mechanism (filter box, rocker arm, turntable and first motor), causing the squid to continuously tumble and shift within the filter box, promoting rapid removal of surface moisture. Compared with the traditional static draining method, this can shorten the dehydration time, significantly reducing energy consumption costs in subsequent drying processes while improving the processing efficiency of aquatic products.

[0039] The present invention will be further described in detail below with reference to the accompanying drawings.

[0040] Example 1:

[0041] refer to Figures 1-3 An ultrasonic-based squid cleaning device includes a base 22, on which a housing 1 is inclined from left to right. Preferably, the inclination angle is 5-8°. A feed pipe 8 is provided on the top left side of the housing 1. The upper end of the feed pipe 8 is flared outward. A filter cylinder 5 is rotatably arranged inside the housing 1. The mesh diameter of the filter cylinder 5 is 3-5mm, which is smaller than the minimum diameter of the squid. The filter cylinder 5 is made of 304 stainless steel.

[0042] A groove 30 is provided on the left side inside the outer casing 1. A rotating rod 2 is rotatably connected between the bottom of the groove 30 and the right side inside the outer casing 1. The rotating rod 2 passes through the filter cylinder 5. Several stirring rods 4 are welded along the length of the rotating rod 2. The rotating rod 2 is made of 45# steel with chrome plating, has a diameter of 20-25mm, and is connected to the outer casing 1 at both ends by deep groove ball bearings of type 6204.

[0043] An impeller 3 is installed on the rotating rod 2 located in the groove 30. The impeller 3 has a diameter of 12-15cm and a blade tilt angle of 30°. A water inlet pipe 6 connected to the groove 30 is connected to the left side of the outer casing 1. A discharge pipe 7 with a valve is connected through the bottom right side of the outer casing 1. Several ultrasonic devices 9 are embedded in the bottom of the outer casing 1. A shaking mechanism is installed on the base 22 located to the right of the discharge pipe 7.

[0044] When water is introduced into the inlet pipe 6, the water flow directly impacts the impeller 3. The impeller 3 rotates after being impacted by the water flow, which in turn drives the rotating rod 2, which is fixedly connected to it, to rotate synchronously. The rotation of the rotating rod 2 drives the stirring rod 4 and the spiral stirring blade 23 to rotate synchronously. The stirring rod 4 continuously stirs the squid, and the spiral stirring blade 23 continuously pushes the squid around the rotating rod 2 outward in a spiral motion to prevent them from piling up.

[0045] The second motor 27 is started, which drives the filter cylinder 5 to rotate through the gear 26 and the gear ring 25, forming a centrifugal force field. The squid to be cleaned is put into the filter cylinder 5. Under the action of the centrifugal force generated by the rotation of the filter cylinder 5, the squid makes a projectile motion in the filter cylinder 5. At the same time, the spatial position is constantly changed with the circumferential motion of the filter cylinder 5, thereby improving the cleaning efficiency.

[0046] During this process, the ultrasonic device 9 at the bottom of the outer shell 1 is activated simultaneously. The high-frequency vibration generated by the device forms a large number of tiny bubbles in the water. These bubbles are continuously generated, grow and burst instantly under the action of ultrasonic waves. The huge impact force released when they burst directly acts on the surface and folds of the squid, which can efficiently break down the mucus and residual impurities on the surface. The rotation of the filter cylinder 5 also drives the surrounding water to form a ring vortex. The vortex and the centrifugal force of the filter cylinder 5 work together to make the surface of the squid fully contact the water. Combined with the ultrasonic cavitation effect, it achieves all-round cleaning. In addition, as the cleaning process proceeds, the water containing impurities can seep out through the mesh of the filter cylinder 5 and be discharged through the first drain pipe 20. After the cleaning is completed, the valve on the discharge pipe 7 is opened and the squid is discharged from the discharge pipe 7.

[0047] refer to Figure 1 , Figure 2 A first drain pipe 20 is inserted and sleeved on the right side of the bottom inside the outer shell 1. By setting the first drain pipe 20, the water used to clean the squid inside the outer shell 1 can be easily drained.

[0048] Example 2:

[0049] refer to Figure 1 , Figure 2 , Figure 4 An ultrasonic-based squid cleaning device includes a vibrating mechanism comprising a filter box 10 located at the bottom right side of a discharge pipe 7. The filter box 10 has a mesh diameter of 2-3 mm. A bracket 11 is bolted to the back of the filter box 10. A rocker arm 12 is hinged to the top and bottom of the inner wall of the bracket 11. A turntable 13 is hinged to the rear end of the bottom of the rocker arm 12. A first motor 14 is fixedly sleeved at the center of the bottom of the turntable 13. The first motor 14 rotates at a speed of 300-500 r / min. A water filter box 15 is embedded in the bottom of the first motor 14. After the device completes the squid cleaning operation, the cleaned squid enters the filter box 10 from the discharge pipe 7. The first motor 14 starts and drives the top turntable 13 to rotate. When the turntable 13 rotates, it pushes the rocker arm 12 to swing back and forth through the hinge point. The back and forth swing of the rocker arm 12 is directly transmitted to the filter box 10 connected to it, causing the filter box 10 to vibrate continuously. The vibration of the filter box 10 can, on the one hand, cause the squid inside to turn and move continuously in the box, avoiding local accumulation, and allowing the excess water attached to the surface of the squid to be removed by the vibration and discharged into the bottom filter box 15. On the other hand, the inertial force generated by the vibration can further remove the fine impurities remaining on the surface of the squid, improving the cleaning cleanliness.

[0050] Preferably, a waterproof plate 16 is bolted to the top of the ultrasonic device 9, and a waterproof cover 17 is rotatably sleeved on the bottom of the output end surface of the first motor 14. By setting the waterproof plate 16 and the waterproof cover 17, water leakage can be prevented from causing water to enter the ultrasonic device 9 and the first motor 14 and causing damage. The waterproof plate 16 is made of food-grade silicone material with a thickness of 3-5mm and is sealed to the outer shell by an O-ring with a diameter of 8mm. The waterproof cover 17 is made of 304 stainless steel and is connected to the output shaft of the first motor 14 by a labyrinth seal structure, with an IP65 waterproof rating to prevent water from entering the electrical components.

[0051] refer to Figure 2 , Figure 3 The filter box 10 has sliders 18 bolted to the front and rear ends on both sides. The filter box 15 has grooves 19 on the front and rear ends on both sides inside. The inside of the grooves 19 is slidably connected to the surface of the sliders 18. By setting the sliders 18 and the grooves 19, the movement of the filter box 10 can be limited and kept stable.

[0052] refer to Figure 1 , Figure 3 A second drain pipe 21 with a valve is provided through the bottom of the front end of the water filter box 15. The water in the water filter box 15 can be easily drained by the second drain pipe 21.

[0053] Preferably, the front and back of the filter box 10 are made of solid plates. By making them solid plates, it is easy to bolt and fix the bracket 11 and the slider 18.

[0054] The ultrasonic device, model 9, is a US-4000 ultrasonic cleaning transducer with a working frequency set at 25-35kHz. At this frequency, dense and stable cavitation bubbles can be formed in the cleaning fluid. The impact force when the bubbles burst can efficiently remove impurities and mucus from the folds on the surface of the squid. This avoids the problem of insufficient impact force due to excessively high frequencies or excessively large bubbles that could mechanically damage the squid meat due to excessively low frequencies. With a rated power of 550W, it meets the requirement of "providing sufficient impact force through the cavitation effect." At this power, the ultrasonic energy can be evenly applied to the cleaning fluid inside the shell, ensuring that all parts of the squid are affected by the cavitation effect when the filter cartridge rotates, avoiding cleaning dead zones. It adopts a waterproof transducer design, with the core transducer components encapsulated in a stainless steel shell. It can be directly embedded in the bottom of the shell, achieving IP67 waterproof rating with a waterproof plate, preventing cleaning fluid leakage from affecting the device's lifespan. It can efficiently convert electrical energy into ultrasonic vibration energy.

[0055] Instructions for use: Pour the squid to be cleaned into the filter cylinder 5 through the feed pipe 8, then add water to the water inlet pipe 6. The water flow directly impacts the impeller 3, causing the impeller 3 to rotate under the impact of the water flow. This, in turn, drives the rotating rod 2, which is fixedly connected to it, to rotate synchronously. This, in turn, drives the rotating rod 2 and the spiral stirring blade 23, which are fixedly connected to it, to rotate synchronously. The stirring rod 4 continuously stirs the squid, and when the spiral stirring blade 23 rotates, it continuously pushes the squid around the rotating rod 2 outward in a spiral motion to prevent accumulation.

[0056] During this process, the ultrasonic device 9 at the bottom of the outer shell 1 is activated, and the high-frequency vibration generated by it forms a large number of tiny bubbles in the water. These bubbles are continuously generated, grow and burst instantly under the action of ultrasonic waves. The huge impact force released when they burst directly acts on the surface and folds of the squid, which can efficiently break down the mucus and residual impurities on the surface. At the same time, the second motor 27 is activated, which drives the gear ring 25 and the filter cylinder 5 to rotate through the gear 26. The squid makes a projectile motion in the filter cylinder 5, and its spatial position changes continuously with the circumferential motion of the filter cylinder 5. The rotation of the filter cylinder 5 also drives the surrounding water to form a ring vortex. The vortex and the centrifugal force of the filter cylinder 5 work together to make the surface of the squid fully contact the water, and achieve all-round cleaning in conjunction with the ultrasonic cavitation effect.

[0057] Furthermore, as the cleaning process proceeds, water containing impurities can seep through the mesh of the filter cartridge 5 and be discharged. After cleaning, the squid discharge pipe 7 discharges the squid. When the device completes the squid cleaning operation, the cleaned squid enters the filter box 10 from the discharge pipe 7. The first motor 14 is started, and the first motor 14 drives the top turntable 13 to rotate. When the turntable 13 rotates, it pushes the rocker arm 12 to swing back and forth through the hinge point. The back and forth swing of the rocker arm 12 is directly transmitted to the filter box 10 connected to it, causing the filter box 10 to vibrate continuously. The vibration of the filter box 10 can, on the one hand, cause the squid inside to continuously turn and move within the box, avoiding local accumulation, and allowing excess water attached to the surface of the squid to be removed under the action of vibration and discharged into the bottom water filter box 15. On the other hand, the inertial force generated by the vibration can further remove the fine impurities remaining on the surface of the squid, improving the cleaning cleanliness.

[0058] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
