Description

Technical Field

[0001] This invention relates to the field of fish processing technology, specifically to a pre-treatment and cleaning device for fish. Background Technology

[0002] During the processing of fish products, after the fish are slaughtered, their surface will have some blood, mucus, and other dirt attached to it. Therefore, it is necessary to clean the fish meat uniformly using a cleaning machine. Common fish meat cleaning machines include bubble cleaning machines. Under the action of bubbles and water flow, the fish meat can be turned over, and the impact force generated when the bubbles burst on the surface of the fish meat can remove the dirt from the surface.

[0003] The cleaning water inside the bubble cleaning machine circulates and is filtered, saving water. During the water circulation process, cleaning water is sprayed downwards through nozzles above the cleaning tank, promoting the movement of the fish. However, conventional nozzles remain vertically downwards, making it difficult to adjust the spray angle. Since the fish mainly moves vertically, this can create blind spots in the spray, thus warranting further improvement. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a pre-treatment and cleaning device for fish meat, which has the following beneficial effects:

[0018] 1. In the pre-treatment and cleaning device for fish meat, during the rotation of the rotating drum, the sliding column slides along inclined groove one, arc groove two, inclined groove two, and arc groove one, driving collar two and push plate to move back and forth, thereby driving sliding frame to move back and forth. Combined with the meshing of the rack plate and gears, this drives the turntable, rotating tube two, rotating tube one, and sleeve to rotate back and forth, causing the nozzle body to swing back and forth. The water jet from the nozzle body is inclined, causing the fish meat to move both longitudinally and laterally; thus achieving adjustable nozzle body angle and improving the fish meat turning effect.

[0019] 2. The pre-treatment and cleaning device for fish meat can move the fish meat in the cleaning tank laterally during the deflection of the nozzle body. When the water jets from the nozzle bodies on two adjacent drain pipes spray between the two drain pipes, the fish meat can be gathered together. Then, through the impact of the water flow, the gathered fish meat is turned over, and the fish meat rubs against each other, which enhances the cleaning effect on the fish meat.

[0020] 3. The pre-treatment and cleaning device for fish meat uses a motor to drive the front shaft to rotate. This, combined with the transmission of sprockets and chains, drives the rear shaft to rotate synchronously. As the stirring blades rotate with the shafts, they agitate the cleaning water inside the return tank, enhancing its flow and removing air bubbles. This reduces the damage to the water pump caused by air bubbles and extends its service life.

[0021] 4. The pre-treatment and cleaning device for fish meat, while the rotating shaft rotates, the spiral blades and the rotating drum rotate synchronously, which can transport the cleaning water in the return tank to the filter cotton, and the dirt can be temporarily stored by the dirt accumulation tank.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figures 1-14A pre-treatment and cleaning device for fish meat includes a receiving tank 100. Two partition plates 200 are fixedly installed inside the receiving tank 100, dividing the interior of the receiving tank 100 into three parts: a cleaning tank in the middle, and return tanks on both sides. A mesh screen 201 is provided on the right half of each partition plate 200, and the cleaning tank and return tank are connected by the mesh screen 201. Fish meat to be cleaned is placed into the cleaning tank, and the mesh screen 201 prevents the fish meat from entering the return tank. A discharge assembly 300 is provided inside the cleaning tank. The right half of the discharge assembly 300 is horizontal, and the left half is inclined. The cleaned fish meat is transferred out through the discharge assembly 300. A bubble generator 400 is provided in the right half of the discharge assembly 300, which introduces a large number of bubbles into the cleaning tank for turning and cleaning the fish meat.

[0045] A liquid supply assembly 500 is fixedly installed at the left end of the receiving tank 100. Four drain pipes 505 are connected to the right end of the liquid supply assembly 505. The other end of the drain pipes 505 is sealed. Each drain pipe 505 has through holes 506 arranged in an array. The drain pipes 505 are L-shaped. The horizontal part of the drain pipes 505 is located directly above the receiving tank 100. The through holes 506 are opened through the horizontal part of the drain pipes 505. The liquid supply assembly 500 is used to draw cleaning water from the two return tanks and deliver the cleaning water to the drain pipes 505. Then, the cleaning water is discharged from the through holes 506 and finally sprayed into the cleaning tank.

[0046] Sprayer assemblies 600 are installed on four drain pipes 505. A stirring assembly 700 is rotatably connected in two return tanks. A transmission assembly 800 is installed between the left end of the stirring assembly 700 and the left end of the sprayer assembly 600. A filter assembly 900 is installed in the left end of each return tank. The liquid supply assembly 500 delivers water from the return tank to the sprayer assembly 600 and sprays it into the cleaning tank through the sprayer assembly 600. The stirring assembly 700 drives the sprayer assembly 600 to reciprocate and deflect through the transmission assembly 800 to adjust the spray angle.

[0047] Please see Figures 2-3 A horizontal pressure plate 202 is fixedly installed on one side of each of the two partition plates 200. The horizontal pressure plate 202 is located directly below the partition net 201. An inclined pressure plate 203 is integrally formed on the left end of the horizontal pressure plate 202. An arc-shaped buckle plate 204 is fixedly installed on the right end of the horizontal pressure plate 202 and the left end of the inclined pressure plate 203. A guide plate 205 is fixedly installed between the right ends of the two partition plates 200. An arc-shaped baffle plate 206 is integrally formed at the bottom of the guide plate 205. The arc center of the arc baffle plate 206 coincides with the arc center of the arc buckle plate 204 on the right side, and the inner diameter of the arc baffle plate 206 is larger than the outer diameter of the arc buckle plate 204.

[0048] Please see Figure 4The discharge assembly 300 includes two driven rollers 301, which are rotatably connected to the right half of the partition plate 200. The two driven rollers 301 are at the same height and are both located below the horizontal pressure plate 202. A drive roller 302 is rotatably connected to the top left end of the two partition plates 200. The diameter of the drive roller 302 is larger than the diameter of the driven rollers 301. An annular conveyor belt 303 is provided on the outer side of the two driven rollers 301 and the drive roller 302. The surface of the annular conveyor belt 303 is provided with an array of through-holes for drainage. The outer surface of the annular conveyor belt 303 is fixed with an array of protrusions 304. The gap between the arc-shaped baffle plate 206 and the arc-shaped buckle plate 204 is used to avoid the protrusions 304. The horizontal pressure plate 202 and the inclined pressure plate 203 are attached to the edge of the upper surface of the annular conveyor belt 303, and two arc-shaped fasteners 204 are attached to both ends of the annular conveyor belt 303 respectively. The connection between the horizontal pressure plate 202 and the inclined pressure plate 203 is an arc transition, so that the annular conveyor belt 303 is smoother when passing through the connection between the horizontal pressure plate 202 and the inclined pressure plate 203.

[0049] A motor 305 is fixedly installed at the front end of the drive roller 302, and a hopper 306 is fixedly installed at the top left end of the two receiving troughs 100. The drive roller 302 is driven to rotate by the motor 305, which in turn drives the annular conveyor belt 303 to move. The upper part of the annular conveyor belt 303 moves from right to left, and the fish meat on the annular conveyor belt 303 is blocked by the convex strips 304, which facilitates the transfer of the cleaned fish meat to the hopper 306, and then the fish meat is discharged through the hopper 306.

[0050] Please see Figures 5-6 The bubble generator 400 includes a square cylinder 401 fixedly installed between two partition plates 200, which seal both ends of the square cylinder 401. The square cylinder 401 is located inside the right half of the discharge assembly 300. Aeration stones 402 are arranged in an array on the top of the square cylinder 401. A U-shaped plate 403 is fixedly installed between the top and bottom walls of the square cylinder 401. The U-shaped plate 403 is U-shaped, and an air flow channel is reserved between the rear end of the U-shaped plate 403 and the partition plate 200. The U-shaped plate 403 surrounds the left, right and front sides of the aeration stones 402. An air guide pipe 404 is fixedly installed on the front partition plate 200. The air guide pipe 404 communicates with the inside of the square cylinder 401 and passes through the receiving groove 100. An air pump 405 is connected to the front end of the air guide pipe 404. Air is supplied into the square cylinder 401 through the cooperation of the air pump 405 and the air guide pipe 404. The air is blocked by the U-shaped plate 403, which can prevent the concentrated airflow into a single aeration stone 402. The air flows backward along the space between the U-shaped plate 403 and the side wall of the square cylinder 401, and then a large number of bubbles are discharged into the cleaning tank through the aeration stone 402.

[0051] Please see Figures 7-9The liquid supply assembly 500 includes a connecting pipe 501 connected to the left end of the receiving tank 100. Both ends of the connecting pipe 501 are connected to two return tanks respectively. A connecting pipe 502 is connected to the middle of the connecting pipe 501, and a water pump 503 is installed on the connecting pipe 502. A water storage tank 504 is connected to the right end of the connecting pipe 502. The water storage tank 504 is fixedly installed on the right half of the front side of the receiving tank 100. Four drain pipes 505 are equidistantly fixed to the top of the water storage tank 504, and the bottom ends of the drain pipes 505 extend into the interior of the water storage tank 504. The stirring assembly 700 rotates within the return tank, promoting water flow and expelling a large number of air bubbles from the water. This reduces damage to the water pump 503 caused by air bubbles and extends its service life. Water from the return tank is pumped into the water storage tank 504 via the water pump 503, connecting pipe 2 502, and connecting pipe 1 501. Under the hydraulic pressure inside the water storage tank 504, the cleaning water enters the drain pipe 505 and then enters the nozzle assembly 600 through the through hole 506.

[0052] Four supports 507 are fixedly arranged between the top of each partition plate 200 and the receiving groove 100. A support plate 508 is fixedly installed on the top of the support plate 507, and the horizontal part of the drain pipe 505 is fixedly fixed to the support plate 508. The drain pipe 505 is supported by the cooperation of the support plate 507 and the support plate 508.

[0053] Please see Figures 7-10 The nozzle assembly 600 includes a sleeve 601, which is fitted onto the horizontal portion of the drain pipe 505. The sleeve 601 corresponds one-to-one with the through hole 506. The inner diameter of both ends of the sleeve 601 is equal to the outer diameter of the drain pipe 505, and the inner diameter of the sleeve 601 is greater than the outer diameter of the drain pipe 505. The sleeve 601 is connected to the drain pipe 505 through the through hole 506.

[0054] A fixed tube 602 is fixedly installed at the bottom of sleeve 601. A rotating tube 603 is fixedly installed between two adjacent sleeves 601. A rotating tube 604 is fixedly installed on the frontmost and rearmost sleeves 601. A turntable 605 is fixedly installed at the other end of the rotating tube 604. Both rotating tubes 603 and 604 are sleeved on the outside of drain pipe 505, and the inner diameters of both rotating tubes 603 and 604 are equal to the outer diameter of drain pipe 505. The turntable 605 is attached to the support plate 508. Thus, through the connection between rotating tubes 603 and 604, the sleeves 601 on drain pipe 505 rotate synchronously when the turntable 605 rotates.

[0055] A nozzle body 606 is fixedly installed at the bottom of the fixed pipe 602. The nozzle body 606 has an isosceles triangular cross-section, and its width gradually decreases from top to bottom. Air inlet pipes 607 are connected to both sides of the top of the nozzle body 606. Thus, the cleaning water inside the drain pipe 505 is forced into the sleeve 601 through the through hole 506, and then passes through the fixed pipe 602 into the nozzle body 606. As the water flows along the nozzle body 606, the water pressure gradually increases. Due to the water flow inside the nozzle body 606, the air pressure inside the nozzle body 606 is lower than the external air pressure, allowing outside air to enter the nozzle body 606 through the air inlet pipes 607 and be discharged from the nozzle body 606 with the water flow. Furthermore, the water sprayed from the nozzle body 606 acts as a water curtain within the cleaning tank.

[0056] The nozzle assembly 600 also includes two sliding frames 610. Two L-shaped plates 609 are fixedly mounted on the surface of each support plate 508. The sliding frame 610 is slidably connected between the two L-shaped plates 609. A connecting plate 611 is fixedly mounted between the left ends of the two sliding frames 610, allowing the two sliding frames 610 to move synchronously. Two rack plates 612 are arrayed and fixedly fixed on the top and bottom walls of each sliding frame 610. The four rack plates 612 are equidistantly distributed in the left-right direction. A gear 608 is fixedly mounted on the circumference of each drain pipe 505, and the rack plates 612 mesh with the gears 608. Adjacent gears 608 mesh with the upper and lower rack plates 612 respectively. During the left-right movement of the sliding frame 610, the adjacent gears 608 rotate in opposite directions. When the nozzle body 606 on two adjacent drain pipes 505 sprays water between them, convection is formed inside the cleaning tank, enhancing the agitation of the fish meat in the water. Furthermore, during the deflection of the nozzle body 606, the water jet from the nozzle body 606 acts on the water surface inside the cleaning tank, causing the water inside the cleaning tank to flow laterally along the deflection direction of the nozzle body 606, thus improving the lateral movement of the fish meat. Additionally, during the deflection of the nozzle body 606 on the two adjacent drain pipes 505, the water flow can gather the fish meat together, enhancing the friction between the fish meat.

[0057] Please see Figures 11-12The stirring assembly 700 includes two rotating shafts 701 rotatably connected to the right end of the receiving tank 100. The two shafts 701 are located in two return tanks respectively. Stirring blades 702 are fixedly arranged on the surface of each shaft 701. A sprocket 703 is fixedly mounted on the circumferential surface of the right end of each shaft 701. The two sprockets 703 are connected by a chain 704. Through the transmission action of the sprockets 703 and the chain 704, the two shafts 701 rotate synchronously. When the shafts 701 rotate, the stirring blades 702 agitate the water in the return tanks, promoting the flow of the washing water and removing air bubbles. A protective cover 705 is fixedly installed on the right side of the receiving tank 100. The protective cover 705 is fitted over the outside of the sprocket 703 and chain 704, protecting the sprocket 703 and chain 704 and preventing fish meat or sewage from falling onto the sprocket 703 and chain 704 when the fish meat is put into the receiving tank 100 from the right end. A second motor 706 is fixedly installed on the right side of the protective cover 705, and the output end of the second motor 706 is fixedly installed to the front rotating shaft 701.

[0058] Please see Figures 11-14 The transmission assembly 800 includes a right baffle 801 and a left baffle 802 fixedly installed in the left half of the return channel. The right baffle 801 is located to the right of the left baffle 802. Both the right baffle 801 and the left baffle 802 have through holes 803. A collar 804 is fixedly installed on opposite sides of the right baffle 801 and the left baffle 802. The through holes 803 communicate with the collar 804. The axes of the through holes 803 and the collar 804 coincide with the axis of the rotating shaft 701.

[0059] The transmission assembly 800 also includes a rotating drum 805. Both ends of the rotating drum 805 are fixedly mounted with annular flanges 806. The cross-section of the collar 804 is L-shaped. The annular flanges 806 are rotatably connected inside the collar 804. The right half of the return tank and the filter assembly 900 are separated by the right baffle 801 and the left baffle 802, and are connected by the rotating drum 805, so that the cleaning water in the return tank can pass through the rotating drum 805 and enter the filter assembly 900.

[0060] A spiral blade 807 is fixedly installed on the circumferential surface of the left end of the rotating shaft 701. The spiral blade 807 is fixedly installed on the inner wall of the rotating drum 805. Thus, when the rotating shaft 701 rotates, it drives the rotating drum 805 to rotate in conjunction with the spiral blade 807. And through the rotation of the spiral blade 807, the cleaning water in the return tank flows into the filter assembly 900.

[0061] The outer wall of the rotating cylinder 805 is provided with an inclined groove 808, an arc groove 809, an arc groove 810, and an inclined groove 811. The inclined groove 808, arc groove 809, arc groove 810, and inclined groove 811 are connected to form a ring. The inclined groove 808 and the inclined groove 811 are both lower on the left and higher on the right. The arc groove 809 is connected between the left ends of the inclined groove 808 and the inclined groove 811, and the arc groove 810 is connected between the right ends of the inclined groove 808 and the inclined groove 811.

[0062] A second collar 812 is fitted around the outer side of the rotating drum 805. A sliding column 813 is fixedly fixed through the second collar 812. One end of the sliding column 813 is hemispherical inside the second collar 812 and is slidably connected within the inclined groove 808, the arc groove 809, the arc groove 810, and the inclined groove 811. A push plate 814 is fixedly installed on the outer wall of the second collar 812, and the top of the push plate 814 is fixedly installed on the left end of the sliding frame 610. During the rotation of the rotating drum 805, the rotating drum 805, located on the side wall of the inclined groove 808, squeezes and pushes the sliding column 813, causing the second collar 812, the sliding column 813, and the push plate 814 to move to the right. The rotating drum 805, located on the inner wall of the inclined groove 811, squeezes and pushes the sliding column 813, causing the second collar 812, the sliding column 813, and the push plate 814 to move to the left. When the sliding column 813 slides within the arc-shaped groove 809 and the arc-shaped groove 810, the positions of the collar 812 and the push plate 814 do not change. At this time, the nozzle body 606 maintains its tilted state after deflection. Thus, during the rotation of the rotating drum 805, the collar 812, the sliding column 813, and the push plate 814 are driven to move back and forth, thereby driving the sliding frame 610 to slide back and forth.

[0063] Please see Figure 12 Each filter assembly 900 includes a clamping plate 901 fixedly installed in the left end of the return channel. A sealing plate 902 is fixedly installed on the top of the clamping plate 901. The clamping plate 901 and the sealing plate 902 together form a sealed cavity in the left end of the return channel. The liquid supply assembly 500 communicates with the sealed cavity. Water passage grooves 903 are arrayed through the surface of the clamping plate 901. A receiving frame 904 is inserted between the clamping plate 901 and the left baffle 802. Filter cotton 905 is embedded in the receiving frame 904. A dirt accumulation groove 906 is opened on the right side of the filter cotton 905. The cleaning water is filtered through the filter cotton 905, and dirt can be temporarily stored inside the dirt accumulation groove 906.

[0064] In use, the fish meat is put into the cleaning tank from the right end of the receiving tank 100. The air pump 405 and the air guide pipe 404 introduce outside air into the square cylinder 401. Then, through the setting of the aeration stone 402, a large number of bubbles are introduced into the cleaning water. After passing through the drain holes on the annular conveyor belt 303, the bubbles act on the fish meat, promoting the fish meat to turn over and removing dirt from the surface of the fish meat.

[0065] The cleaning water in the return tank is drawn through connecting pipe 501, connecting pipe 502, and water pump 503 and transported to water storage tank 504. Then, under the water pressure inside water storage tank 504, the cleaning water enters drain pipe 505, passes through through hole 506 into sleeve 601, and is finally sprayed into cleaning tank through nozzle body 606, further promoting the fish meat to turn over and removing dirt from the surface of the fish meat under the impact of water flow. In addition, as the cleaning water flows in nozzle body 606, outside air enters nozzle body 606 through air inlet pipe 607 and is sprayed into cleaning tank along with the water flow.

[0066] The motor 706 drives the front shaft 701 to rotate, which, in conjunction with the transmission action of the sprocket 703 and chain 704, drives the rear shaft 701 to rotate synchronously. As the stirring blade 702 rotates with the shaft 701, it agitates the cleaning water inside the return tank, enhancing the flow effect of the cleaning water and thus removing air bubbles from the cleaning water.

[0067] During the rotation of the shaft 701, the spiral blades 807 and the rotating drum 805 rotate synchronously, causing the cleaning water inside the return tank to be transported into the sludge collection tank 906. After being filtered by the filter cotton 905, the cleaning water passes through the water tank 903 and enters the sealed cavity. Furthermore, when the connecting pipe 501 draws the cleaning water from the sealed cavity, it creates a negative pressure inside the sealed cavity, further promoting the cleaning water to pass through the rotating drum 805 and the filter cotton 905 into the sealed cavity.

[0068] During the rotation of the rotating drum 805, the sliding column 813 slides along the inclined groove 808, the arc groove 810, the inclined groove 811, and the arc groove 809, driving the collar 812 and the push plate 814 to move back and forth, thereby driving the sliding frame 610 to move back and forth. Combined with the meshing of the rack plate 612 and the gear 608, this drives the turntable 605, the rotating tube 604, the rotating tube 603, and the sleeve 601 to rotate back and forth, causing the nozzle body 606 to swing back and forth. The water jet from the nozzle body 606 is inclined, causing the fish meat to move laterally while turning longitudinally, thus enhancing the turning effect of the fish meat.

[0069] The motor 305 drives the active roller 302 to rotate, which in turn moves the annular conveyor belt 303. The upper part of the annular conveyor belt 303 moves the cleaned fish meat to the left, and the convex strip 304 blocks the fish meat from falling off the annular conveyor belt 303, thereby discharging the cleaned fish meat from the left end of the receiving tank 100.

[0070] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
