Description

Technical Field

[0001] This invention relates to the field of fish skin cleaning and processing technology, specifically to a skin washing device for processing fish collagen peptide raw materials. Background Technology

[0002] In the early stages of processing collagen peptide raw materials such as fish skin, the cleaning process is crucial. This step requires the use of physical or chemical methods to remove impurities such as inorganic salts, fats, and mucus adhering to the surface of the raw materials, creating a clean raw material foundation for subsequent collagen extraction processes. Among these methods, bubble cleaning machines are commonly used physical cleaning equipment. They utilize the impact force generated by the bursting of high-pressure bubbles, combined with the tumbling action of water flow, to effectively peel off and wash away dirt from the surface of the materials, ensuring the cleanliness of the raw materials.

[0003] Existing technology, such as Chinese utility model patent with publication number CN205005818U, discloses a fish skin cleaning machine, including a machine body. The machine body has a first cleaning water outlet, a second cleaning water outlet, and a third cleaning water outlet on three sides. The machine body includes a discharge mechanism, with a spray device above the discharge mechanism and a buffer device at the discharge port. A receiving trough is located below the buffer device. This fish skin cleaning machine, through improvements to the cleaning water outlet, facilitates the cleaning of debris inside the machine and prevents the drain pipe from being blocked by debris. The spray device sprays the fish skin while it is being discharged, thoroughly cleaning the dirty water attached to the surface, saving manpower and improving cleaning efficiency. The buffer device prevents water from splashing onto workers.

[0004] However, the fish skin cleaning machine mentioned in the above patent has a narrow scope of application. Currently, bubble cleaning machines are commonly used to clean fish skin, lobsters, or fruits and vegetables. For example, Chinese utility model patent CN212787276U discloses a flipping lobster bubble cleaning machine, including a frame, a moving mechanism mounted on the frame, a flipping mechanism mounted on the frame, and a bubble mechanism at the bottom of the frame. The frame includes a water tank and a frame body. The moving mechanism includes a perforated chain conveyor belt mounted inside the water tank, a drive motor fixedly connected to the frame body and connected to the perforated chain conveyor belt, and baffles between adjacent perforated chain plates. The bubble mechanism includes several bubble nozzles evenly distributed at the bottom of the water tank. The water tank is equipped with a water supply and drainage mechanism. This bubble cleaning machine uses a perforated chain conveyor belt to transport lobsters and uses a rotating lifting post to poke open the lobster clumps, achieving a rapid and thorough cleaning effect. By setting several separators, it can flip and wash different parts of the lobster.

[0005] However, the aforementioned bubble cleaning machine still has certain drawbacks: In the processing of fish skin collagen peptides, the fish skin mucus generated during the cleaning process is highly viscous, easily aggregates, and mixes with water to form a colloidal substance, severely affecting the purification effect of the water circulation system. Existing bubble cleaning machines use a single filter screen or ordinary filter bag in their water circulation system, which cannot effectively intercept the mucus. The mucus easily adheres to the filter surface, forming a dense blockage layer, resulting in low filtration efficiency, requiring frequent shutdowns for cleaning, and poor production continuity. Secondly, the density difference between fish skin mucus and water is small, and traditional sedimentation tanks cannot quickly separate the mucus, resulting in high turbidity in the circulating water, requiring a large amount of fresh water to be added, thus increasing production costs. Therefore, there is an urgent need for a fish skin washing water circulation device that is highly efficient in separating mucus, has low maintenance costs, and is suitable for continuous production. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a skin-washing device for processing fish collagen peptide raw materials, which can separate and treat mucus, thereby improving the purification effect of the water circulation system.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a washing device for processing fish collagen peptide raw materials, comprising a washing chamber, a mesh belt conveyor, and a spraying mechanism. A water pump is fixedly connected to the lower end of the washing chamber. An inlet pump and an outlet pump are fixedly connected to one side of the washing chamber. A filter sedimentation cylinder is provided between the inlet pump and the outlet pump. A connecting frame is fixedly connected to the outer wall of the filter sedimentation cylinder, and the connecting frame is fixedly connected to the washing chamber. The upper end of the filter sedimentation cylinder is cylindrical, and the lower end is conical. An inlet pipe is fixedly connected to the side of the upper end of the filter sedimentation cylinder near the inlet pump, and an outlet pipe is fixedly connected to the other side of the upper end of the filter sedimentation cylinder. The inlet end of the inlet pump is fixedly connected to the end of the water pump away from the washing chamber. The outlet end of the inlet pump is fixedly connected to the inlet pipe, and the inlet end of the outlet pump is fixedly connected to the outlet pipe. A return pipe is fixedly connected to the outlet end of the outlet pump, and the other end of the return pipe is fixedly connected to the spraying mechanism.

[0008] Furthermore, a three-way connecting pipe is rotatably connected to the end of the outlet pipe away from the outlet pump. Solenoid valves are provided at both the upper and lower ends of the three-way connecting pipe. The solenoid valves are connected to the flange of the three-way connecting pipe by a first fixing bolt. A water inlet chamber is provided at the end of the solenoid valve away from the three-way connecting pipe. The water inlet chamber is connected to the flange of the solenoid valve by a second fixing bolt. Multiple filter bags are installed at the end of the water inlet chamber away from the solenoid valve.

[0009] Furthermore, the water inlet chamber has multiple water outlet holes at the end away from the solenoid valve, and a threaded ring that matches the water outlet holes is fixedly connected to the water inlet chamber. A threaded sleeve is threadedly connected to the outside of the threaded ring, and the end of the filter bag is located between the threaded sleeve and the threaded ring.

[0010] Furthermore, the outer wall of the threaded sleeve is fixedly connected with multiple levers, which are evenly distributed.

[0011] Furthermore, a rotating ring is fixedly connected to the outer wall of the end of the water outlet pipe away from the water pump. A rotating pipe is fitted on the outside of the rotating ring and fixedly connected to the three-way connecting pipe. Threaded holes are opened on the upper and lower sides of the rotating pipe. A threaded rod is threadedly connected to one of the threaded holes, and a knob is fixedly connected to the top of the threaded rod.

[0012] Furthermore, a backwash hole is provided on the outer wall of the water inlet chamber near the water outlet pipe. A connecting hose connected to the backwash hole is fixedly connected to the outer wall of the water inlet chamber. A ball valve is fixedly connected to the other end of the connecting hose. The other end of the ball valve is fixedly connected to the return water pipe. The ball valve is connected to the return water pipe.

[0013] Furthermore, a waste discharge port is provided at the bottom of the filter sedimentation cylinder, and a drain valve is fixedly connected to the middle position of the waste discharge port.

[0014] Furthermore, a left support frame is fixedly connected to the bottom of the inlet pump, and a right support frame is fixedly connected to the bottom of the outlet pump. Both the left and right support frames are fixedly connected to the outer wall of the cleaning chamber.

[0015] Furthermore, the filter sedimentation cylinder is provided with an inner filter screen inside. The top and bottom of the inner filter screen are fixedly connected to an inner frame. A connecting plate is fixedly connected between two inner frames. A fixing plate is fixedly connected to the side of the inner frame away from the inner filter screen. The end of the fixing plate away from the inner frame is fixedly connected to the inner wall of the filter sedimentation cylinder. A limiting ring is fixedly connected to the outer wall of the inner frame. An outer frame is rotatably connected to the outside of the inner frame. A limiting groove matching the limiting ring is opened on the inner side of the outer frame. An outer filter screen is fixedly connected between two outer frames. Multiple equally spaced baffles are fixedly connected to the outer wall of the outer frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Water from the cleaning chamber is pumped into the filter sedimentation cylinder by the inlet pump. Since the upper end of the filter sedimentation cylinder is cylindrical and the lower end is conical, the water will rotate and fall along the inner wall of the filter sedimentation cylinder, thereby enhancing the centrifugal force field and causing the mucus to adhere to the inner wall of the filter sedimentation cylinder. Finally, the mucus will gradually fall under the action of gravity. The outlet pump will pump out the clean water in the middle of the filter sedimentation cylinder and inject it into the spray mechanism for recycling through the return water pipe, thereby improving the separation efficiency of the mucus.

[0017] 2. The water in the middle of the sedimentation tank is filtered by the filter bag to prevent any possible mucus from entering the outlet pipe and causing blockage of the outlet pump or spray mechanism.

[0018] 3. After the filter bag has been used for a certain period of time, the threaded rod can be unscrewed and the three-way connecting pipe can be rotated to rotate the filter bag immersed in the water to the top. Then, the solenoid valve located above the outlet pipe can be closed and the ball valve can be opened to backwash the filter bag after use, so that it can be used again. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Example Please see Figures 1 to 10 A washing device for processing fish collagen peptide raw materials includes a washing chamber 1, a mesh belt conveyor 2, and a spraying mechanism 9. A water pump 3 is fixedly connected to the lower end of the washing chamber 1. An inlet pump 4 and an outlet pump 7 are fixedly connected to one side of the washing chamber 1. A filter sedimentation cylinder 5 is provided between the inlet pump 4 and the outlet pump 7. A connecting frame 6 is fixedly connected to the outer wall of the filter sedimentation cylinder 5 and is fixedly connected to the washing chamber 1. The upper end of the filter sedimentation cylinder 5 is cylindrical, and the lower end of the filter sedimentation cylinder 5... The filter sedimentation cylinder 5 is conical. An inlet pipe 29 is fixedly connected to the upper end of the filter sedimentation cylinder 5 near the water inlet pump 4. An outlet pipe 10 is fixedly connected to the other upper end of the filter sedimentation cylinder 5. The inlet end of the water inlet pump 4 is fixedly connected to the end of the water pump 3 away from the cleaning chamber 1. The outlet end of the water inlet pump 4 is fixedly connected to the inlet pipe 29. The inlet end of the outlet pump 7 is fixedly connected to the outlet pipe 10. A return pipe 8 is fixedly connected to the outlet end of the outlet pump 7. The other end of the return pipe 8 is fixedly connected to the spraying mechanism 9.

[0023] When filtering and recycling water, the inlet pump 4 first draws water from the cleaning chamber 1 through the pump pipe 3 and injects it into the filter sedimentation cylinder 5. Since the inlet pipe 29 is tangent to the upper end of the filter sedimentation cylinder 5, the water entering the filter sedimentation cylinder 5 is guided to form a high-speed vortex. Centrifugal force throws the viscous clumps against the cylinder wall of the filter sedimentation cylinder 5 to achieve efficient separation. The separated viscous will then naturally settle to the lower end of the filter sedimentation cylinder 5 for easy discharge. The end of the outlet pipe 10, away from the outlet pump 7, is located in the middle of the filter sedimentation cylinder 5. The water near the outlet pipe 10 is clean water, which can be directly drawn out by the outlet pump 7 and injected into the spray mechanism 9 through the return pipe 8 for recycling. The entire process utilizes the physical centrifugal principle to efficiently separate viscous, without the need for complex chemical treatment. The conical bottom design allows the viscous to settle naturally, eliminating the need for additional power for sewage discharge. In addition, the cleaning chamber 1, the mesh belt conveyor 2, and the spray mechanism 9 are all existing mature products and will not be described in detail here.

[0024] As a preferred embodiment of the present invention, a three-way connecting pipe 11 is rotatably connected to the end of the water outlet pipe 10 away from the water outlet pump 7. Solenoid valves 17 are provided at both the upper and lower ends of the three-way connecting pipe 11. The solenoid valves 17 are connected to the flange of the three-way connecting pipe 11 by a first fixing bolt 27. A water inlet chamber 18 is provided at the end of the solenoid valve 17 away from the three-way connecting pipe 11. The water inlet chamber 18 is connected to the flange of the solenoid valve 17 by a second fixing bolt 28. Multiple filter bags 23 are installed at the end of the water inlet chamber 18 away from the solenoid valve 17.

[0025] Specifically, the filter bag 23 filters the water entering the outlet pipe 10, thereby improving the separation effect of mucus and preventing any residual mucus from entering the outlet pump 7 through the outlet pipe 10. Meanwhile, the filter bag 23, which is lower than the outlet pipe 10, is always submerged in the water. When the submerged filter bag 23 becomes clogged with mucus and needs cleaning, simply open the solenoid valve 17 at the upper end of the three-way connecting pipe 11 and rotate the three-way connecting pipe 11 180° to place the unused filter bag 23 into the water. The filter bag 23 to be cleaned will then be above the water surface. Simply close the solenoid valve 17 near the filter bag 23, and then remove the filter bag 23 for cleaning or replacement. The entire process is simple, convenient, and easy to operate, and the outlet pump 7 does not need to be shut down throughout the process, nor does the entire equipment need to be stopped. Furthermore, the ability to switch between the filter bags 23 at the upper and lower ends of the three-way connecting pipe 11 shortens downtime for cleaning.

[0026] As a preferred technical solution of the present invention, the water inlet chamber 18 is provided with a plurality of water outlet holes 20 at the end away from the solenoid valve 17, and a threaded ring 19 matching the water outlet holes 20 is fixedly connected to the water inlet chamber 18. A threaded sleeve 21 is threadedly connected to the outside of the threaded ring 19, and the end of the filter bag 23 is located between the threaded sleeve 21 and the threaded ring 19.

[0027] Specifically, when disassembling the filter bag 23, simply unscrew the threaded sleeve 21 to remove the filter bag 23 from the water inlet chamber 18. The threaded sleeve 21 can also quickly fix the filter bag 23. The entire process can be disassembled and cleaned without tools, improving maintenance efficiency.

[0028] It is worth noting that the threaded sleeve 21 and the threaded ring 19 are both fixedly connected to a sealing structure (such as a sealing ring) near the filter bag 23. This is common knowledge and existing technology, so it will not be elaborated on here, and it is not shown in the figure.

[0029] As a preferred technical solution of the present invention, a plurality of lever blocks 22 are fixedly connected to the outer wall of the threaded sleeve 21, and the lever blocks 22 are evenly distributed.

[0030] Specifically, rotating the threaded sleeve 21 by using the lever 22 is more labor-saving and convenient.

[0031] As a preferred technical solution of the present invention, a rotating ring 14 is fixedly connected to the outer wall of the end of the water outlet pipe 10 away from the water outlet pump 7. A rotating pipe 12 fixedly connected to the three-way connecting pipe 11 is sleeved on the outside of the rotating ring 14. Threaded holes 13 are opened on the upper and lower sides of the rotating pipe 12. A threaded rod 16 is threadedly connected to one of the threaded holes 13. A knob 15 is fixedly connected to the top of the threaded rod 16.

[0032] Specifically, before rotating to replace the filter bag 23, the threaded rod 16 connected to the threaded hole 13 can be removed. After rotating to replace the filter bag 23, the threaded rod 16 can be reconnected to the threaded hole 13 until the end of the threaded rod 16 abuts against the rotating ring 14, thereby restricting the three-way connecting pipe 11 and preventing the three-way connecting pipe 11 from rotating on its own.

[0033] It should be noted that the rotating pipe 12 is composed of two semi-circular pipes, and the rotating ring 14 is coaxially clamped in the grooves of the two semi-circular pipes. The two semi-circular pipes are then connected and fixed by welding or bonding to complete the assembly of the rotating pipe 12 and the rotating ring 14. At the same time, one end of the rotating pipe 12 can be fixed to the tee connecting pipe 11 by threaded sealing, welding or bonding. The rotating ring 14 is threaded sealed to the water outlet pipe 10. It should be noted that an annular gasket can be placed between the tee connecting pipe 11 and the water outlet pipe 10 to prevent leakage.

[0034] As a preferred technical solution of the present invention, a backwash hole 24 is provided on the outer wall of the water inlet chamber 18 near the water outlet pipe 10. A connecting hose 25 communicating with the backwash hole 24 is fixedly connected to the outer wall of the water inlet chamber 18. A ball valve 26 is fixedly connected to the other end of the connecting hose 25. The other end of the ball valve 26 is fixedly connected to the return water pipe 8. The ball valve 26 is connected to the return water pipe 8.

[0035] Specifically, after the filter bag 23 to be cleaned is rotated above the three-way connecting pipe 11, the solenoid valve 17 connected to it can be closed, and then the ball valve 26 can be opened. At this time, a portion of the water discharged by the water pump 7 will flow into the water inlet chamber 18 through the connecting hose 25, and finally flow from the inside of the filter bag 23 to the outside, thereby washing away the mucus attached to the filter bag 23, thus achieving the effect of backwashing. Backwashing can quickly remove the mucus attached to the filter bag 23, extend the service life of the filter bag 23, and reduce the cost of consumables.

[0036] It is worth noting that the entire tee connector 11 rotates in an alternating forward and reverse manner. That is, after rotating forward (or clockwise), it will rotate in the opposite direction (or counterclockwise) to prevent the connecting hose 25 from getting tangled on the tee connector 11 and causing damage to the connecting hose 25.

[0037] As a preferred technical solution of the present invention, a waste discharge port 30 is provided at the bottom of the filter sedimentation cylinder 5, and a drain valve 31 is fixedly connected to the middle position of the waste discharge port 30.

[0038] Specifically, when there is too much viscous material accumulating inside the filter sedimentation cylinder 5, the drain valve 31 can be opened to discharge the viscous material so that the filter sedimentation cylinder 5 can continue to play the role of water circulation filtration.

[0039] As a preferred embodiment of the present invention, the bottom of the inlet pump 4 is fixedly connected to a left support frame 32, and the bottom of the outlet pump 7 is fixedly connected to a right support frame 33. Both the left support frame 32 and the right support frame 33 are fixedly connected to the outer wall of the cleaning chamber 1.

[0040] Specifically, the left support frame 32 and the right support frame 33 will provide support for the inlet pump 4 and the outlet pump 7, respectively.

[0041] It is worth noting that the device described in this invention is merely to demonstrate its working principle. Adaptive improvements can be made based on it. For example, to improve the filtration and separation effect, activated carbon or other filter media can be added to the filter bag 23, or a motor can be fixedly connected to the side of the filter sedimentation cylinder 5 away from the outlet pipe 10, and the output end of the motor can be fixedly connected to the three-way connecting pipe 11. Then, all valves can be replaced with electric valves to achieve fully automatic control.

[0042] In addition, all electrical devices in this invention (such as inlet pump 4 and outlet pump 7) are electrically connected to the control box of the cleaning machine or the control cabinet in the factory, so as to facilitate the operator to control them.

[0043] As a preferred embodiment of the present invention, the filter sedimentation cylinder 5 is provided with an inner filter screen 37 inside. The top and bottom of the inner filter screen 37 are fixedly connected to an inner frame 35. A connecting plate 36 is fixedly connected between the two inner frames 35. A fixing plate 34 is fixedly connected to the side of the inner frame 35 away from the inner filter screen 37. The end of the fixing plate 34 away from the inner frame 35 is fixedly connected to the inner wall of the filter sedimentation cylinder 5. A limiting ring 38 is fixedly connected to the outer wall of the inner frame 35. An outer frame 39 is rotatably connected to the outside of the inner frame 35. A limiting groove 40 matching the limiting ring 38 is opened on the inner side of the outer frame 39. An outer filter screen 41 is fixedly connected between the two outer frames 39. A plurality of baffles 42 are fixedly connected to the outer wall of the outer frame 39 at equal intervals.

[0044] Specifically, when water enters the filter sedimentation cylinder 5, it rotates and forms a vortex inside the cylinder. The water contains mucus, causing foam to form during the flow. Since the surface tension of the foam is lower than that of pure water, the foam moves towards the center of the filter sedimentation cylinder 5. This foam easily adheres to the surface of the filter bag 23, causing it to become clogged. At this point, the water pushes the baffle 42, which in turn rotates the outer frame 39 and the outer filter screen 41. This causes relative displacement between the outer filter screen 41 and the inner filter screen 37, resulting in relative shearing motion that breaks up the bubbles, reducing the amount of foam. Breaking up the foam prevents the mucus particles carried by the foam from penetrating the filter bag 23, extending the clogging interval of the filter bag 23 and increasing the cleaning interval, thus improving work efficiency.

[0045] It is worth noting that the filter bag 23 located below the water outlet pipe 10 is in the middle of the inner filter screen 37, and the filter bag 23 is below the liquid surface, while the height of the liquid surface is lower than the height of the top of the outer filter screen 41, so that the outer filter screen 41 and the inner filter screen 37 can play a defoaming role.

[0046] 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.
