Description

Technical Field

[0001] This invention relates to the field of mechanical equipment for primary processing of aquatic shellfish, and in particular to an automated integrated equipment for cleaning and grading shellfish. Background Technology

[0002] Currently, the primary processing of small bivalve shellfish in my country still relies heavily on manual labor. The traditional processing method, which involves boiling the shells in hot water to open them, manually peeling the meat, and naturally drying, is commonly used. This method suffers from prominent problems such as low production efficiency, high labor intensity, high meat breakage rate, incomplete removal of mud and sand, and difficulty in standardizing product hygiene and quality.

[0003] Existing shellfish processing equipment is mostly single-function equipment, mainly divided into: separate shell-opening equipment using steam cooking and mechanical prying; separate shell-meat separation equipment using ordinary reciprocating screens, roller extrusion, and brine buoyancy separation; and separate equipment using conventional drum spraying, ultrasonic cleaning, and centrifugal drying. Each processing step is independent, making it impossible to achieve a streamlined, continuous operation of shellfish processing from hot water shell opening, shell-meat separation, deep cleaning to hot air drying.

[0004] According to the search, the authorization announcement number is CN113854345B, entitled "An Intelligent Shellfish Steaming and Opening Equipment", which discloses a device for steaming and opening shellfish using steam; the authorization announcement number is CN216164872U, which discloses a device that allows shellfish to pass through a steaming box, a separation device and a purification device in sequence via a conveyor belt. Summary of the Invention

[0005] To address the technical problems existing in the background art, this invention proposes an automated integrated equipment for cleaning and grading shellfish.

[0006] The present invention proposes an automated shellfish cleaning and grading integrated equipment, including a frame, a heating box and a vibration separation mechanism installed on the frame. Unlike the prior art, it also includes a material holding frame and a lifting mechanism. The material holding frame is used to hold shellfish material, and the lifting mechanism is slidably installed on the frame. The lifting mechanism is used to drive the material holding frame to move up and down so that the material holding frame can enter or leave the heating box.

[0007] The sliding lifting mechanism moves the material container above the inlet end of the vibrating separation mechanism or above the heating box; the vibrating separation mechanism is used to separate the shell and meat of shellfish materials, thereby facilitating the separation of the shell and meat of shellfish materials.

[0008] It also includes a drying mechanism, which is used to dry the meat material separated by the vibration separation mechanism; the outer wall and bottom of the container frame are provided with multiple through holes, which facilitates the heating of the material and the filtration of water stains during the movement of the container frame by the lifting mechanism; the drying mechanism is set between the vibration separation mechanism and the heating box, which reduces the water content of the material entering the vibration separation mechanism and reduces the footprint of the equipment.

[0009] Preferably, the lifting mechanism includes a first winding device with a pull rope fixed to the container frame; the first winding device rotates clockwise to wind the pull rope, thereby raising the container frame; when the first winding device rotates counterclockwise to unwind the pull rope, the container frame moves downward under the force of gravity.

[0010] Preferably, the material container includes a frame, the top of the frame is an inlet, the bottom of the frame is an outlet, and the bottom plate is rotatably mounted on the bottom of the frame to achieve the closing and opening of the outlet. The side of the bottom plate away from the frame is connected to the frame by a pull elastic member. When no force is applied, the pull elastic member is in an elongated state.

[0011] Preferably, it also includes a pull rope, one end of which is mounted on a second winding device, and the other end of which is mounted on the base plate. The second winding device winds the pull rope around itself to pull the base plate downwards, thereby causing the base plate to rotate downwards and opening the discharge port.

[0012] Preferably, the vibration separation mechanism includes a vibration frame mounted on the frame via an elastic support, the vibration frame being provided with a screen and a vibrator for driving the screen to vibrate;

[0013] The frame is equipped with a discharge plate, which is located below the screen and is used to receive meat material that falls off the screen.

[0014] The vibrating frame is equipped with a cover plate, which forms a vibration channel with the screen. The open shellfish material collides with the screen and the cover plate to separate the shell and the meat.

[0015] Preferably, the height of the vibration channel is 2-5 times the maximum size of the shellfish material.

[0016] Preferably, a pad of elastic material is provided between the cover plate and the vibrating frame to achieve different amplitudes for the screen and the cover plate.

[0017] Preferably, the vibrating frame is equipped with a feeding hopper, which has a feeding channel. The inner wall of the feeding hopper gradually slopes downwards towards the center of the feeding channel. The feeding hopper facilitates material loading and prevents material from falling out when the bottom plate opens. During the opening process, the bottom plate is in contact with the inner wall of the feeding hopper. As the bottom plate rotates and opens at a larger angle, the lifting mechanism moves the material container upwards, facilitating material entry into the feeding hopper and preventing material from falling out.

[0018] To improve the quality of separated meat, preferably, the drying mechanism includes a horizontal conveying mechanism and a drying chamber mounted on a frame. The drying chamber is located above the horizontal conveying mechanism, and the inner wall of the drying chamber is equipped with heating elements. A fan is installed on the top of the drying chamber, and the fan blows heated gas inside the drying chamber downwards to dry the meat material on the horizontal conveying mechanism.

[0019] Preferably, the frame is further equipped with a high-pressure cleaning assembly, which is located above the horizontal conveying mechanism and is used to perform high-pressure spraying on the material before drying to remove impurities from the material surface. This further removes impurities such as sand and shell fragments from the meat.

[0020] The automated shellfish cleaning and grading integrated equipment proposed in this invention has a simple structure. Through the setting of the material holding frame, lifting mechanism, etc., it is convenient to heat the shellfish material while facilitating the movement of the material. In addition, during the process of the lifting mechanism moving the shellfish material, water stains in the material holding frame can be removed, and the separation effect of the vibration separation mechanism on the shell and meat of the material can be increased.

[0021] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0028] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] like Figure 1 - Figure 5 The automated shellfish cleaning and grading integrated equipment shown includes a frame 1 and a heating box 2, a vibration separation mechanism 8, and a drying mechanism 5 mounted on the frame 1. The heating box 2 is an electrically heated and insulated box, which contains water at a constant temperature to facilitate heating of the shellfish material and opening of the shellfish. It also includes a material holding frame 3 and a lifting mechanism 4. The material holding frame 3 is used to hold the shellfish material, and the lifting mechanism 4 is horizontally slidably mounted on the frame 1. The lifting mechanism 4 is used to drive the material holding frame 3 to rise or fall so that the shellfish material in the material holding frame 3 can enter or leave the heating box 2. The sliding lifting mechanism 4 moves the material holding frame 3 to above the feeding end of the vibration separation mechanism 8 or above the heating box 2. The vibration separation mechanism 8 is used to separate the shell and meat of the shellfish material, and the separated meat is transported to the drying mechanism 5 for drying.

[0030] The lifting mechanism 4 includes a first winding device 40 with a pull rope 41 on it. The pull rope 41 is connected to the opposite sides of the material container 3. The first winding device 40 rotates forward to wind the pull rope 41, thereby raising the material container 3. When the first winding device 40 releases the pull rope 41, the material container 3 moves downward under the action of gravity.

[0031] Specifically, the material container 3 includes a frame 30, with the top of the frame 30 serving as an inlet and the bottom as an outlet. A bottom plate 31 is laterally rotatably mounted on the bottom of the frame 30 to close and open the outlet. The side of the bottom plate 31 away from the frame 30 is connected to the frame 30 via a pull elastic member 32. When no force is applied, the pull elastic member 32 is in an elongated state, thus ensuring that the bottom plate 31 will not open even if there are shellfish materials inside the material container 3. It should be noted that the pull elastic member 32 can be a spring as in the prior art, with one side of the spring fixed to the inner wall of the frame 30 and the other side of the spring fixed to the bottom plate 31.

[0032] It also includes a pull rope 6, one end of which is mounted on a second winding device 7, and the other end is mounted on a base plate 31. The second winding device 7 winds the pull rope 6 around itself to pull the base plate 31 downwards, causing it to rotate downwards and thus opening the discharge port. When heating or moving the material in the container 3, the second winding device 7 does not pull the pull rope 6. Instead, the elastic element 32 keeps the base plate 31 horizontal and closes the discharge port. The pull rope 6 does not affect its heating in the heating chamber 2. The second winding device 7 allows the pull rope 6 to be in a slack state and immersed in the heating chamber 2 with the container 3. When the discharge port needs to be opened, the second winding device 7 tightens the pull rope to open the base plate 31. During the movement of the container 3, the slack of the pull rope 6 can be adjusted using the second winding device 7 to prevent it from becoming tangled.

[0033] It should be noted that when the material frame 3 is heated in the heating box 2, the bottom and sides of the material frame 3 are separated from the inner wall of the heating box 2, so that the pull rope 6 can enter the heating box 2 together with the material frame 3 for heating.

[0034] Preferably, the base plate 31 is provided with two sets and arranged opposite to each other, and the corresponding elastic member 32 and the pull rope 6 and the second winding device 7 are provided with two sets. When the bottom of the two sets is in a horizontal state, the feed port is closed, and the frame 30 is provided with a limiting member to limit the angle of rotation of the two base plates 31 relative to the frame 30 to prevent the base plate 31 from extending into the frame 30 when no material is placed.

[0035] In some preferred embodiments, the frame 1 is further provided with a horizontal moving mechanism (not shown in the figure), which can be a lead screw and slider mechanism in the prior art. The horizontal moving mechanism is used to drive the lifting mechanism 4 to move horizontally on the frame 1.

[0036] Specifically, the vibration separation mechanism 8 includes a vibration frame 80 mounted on the frame 1 via an elastic support 83. The vibration frame 80 is equipped with a screen 81, through which the separated meat material can fall. The vibration frame 80 is also equipped with a vibrator 82, which is a pneumatic vibrator. The vibrator 82 drives the screen 81 to vibrate relative to the frame 1, thereby separating the shell and meat in open shellfish material. The meat falls through the screen 81. The frame 1 is also equipped with a discharge plate 85, which is located below the screen 81. The meat falling from the screen 81 falls onto the discharge plate 85. The discharge plate 85 is gradually inclined downward from the feed end away from the screen 81 to the feed end closer to the screen 81, thereby facilitating material discharge. The material discharged from the discharge plate 85 enters the drying mechanism 5.

[0037] The frame 1 is also equipped with a water supply pipe 10, which is used to supply water to the discharge plate 85 so that the material on the discharge plate 85 can slide downward.

[0038] Preferably, the frame 1 is provided with a rain pipe 9 connected to the water supply pipe 10. The rain pipe 9 is located above the discharge plate 85. The liquid in the water supply pipe 10 is sprayed onto the discharge plate 85 through the rain pipe 9, which further facilitates the falling of the material.

[0039] Preferably, the vibrating frame 80 is also provided with a cover plate 84, which covers the screen 81 and forms a vibration channel. The height of the vibration channel is 2-5 times the maximum size of the shellfish material. During vibration, the shellfish collides with the cover plate 84, which facilitates the separation of the meat from the shell. Preferably, a pad 86 made of elastic material is provided between the cover plate 84 and the vibrating frame 80. The pad 86 can be made of rubber material. The pad 86 can, on the one hand, allow the cover plate 84 and the screen 81 to have different amplitudes to facilitate the separation of the shell and the meat, and on the other hand, it can facilitate the adjustment of the height of the cover plate 84 according to the different sizes of shellfish material.

[0040] Preferably, the vibrating frame 80 is also provided with a feeding hopper 11, which has a feeding channel. The inner side wall of the feeding hopper 11 is an inclined surface that gradually slopes from top to bottom toward the center of the feeding channel, which facilitates feeding and also facilitates pulling the bottom plate 31 to make the shellfish material in the container frame 3 fall into the feeding hopper 11.

[0041] Preferably, the drying mechanism 5 includes a horizontal conveying mechanism 51 mounted on the frame 1 and a drying chamber 50. The drying chamber 50 is located above the horizontal conveying mechanism 51. Heating elements are provided on the inner wall of the drying chamber 50. A fan is located above the drying chamber 50, blowing heated gas from inside the drying chamber 50 downwards to dry the meat material on the horizontal conveying mechanism 51. The fan is an axial flow fan, with its inlet connected to a duct and its outlet connected to the interior of the drying chamber 50.

[0042] Preferably, the heating element inside the drying chamber 50 is a far-infrared carbon fiber heating tube, and two sets of heating elements are arranged opposite each other, which can form a high-frequency, high-speed circulating hot air, so that the heat is evenly distributed by convection on the surface of the material, avoiding the problems of local overheating or uneven drying. A rain shield is also provided on top of the drying chamber 50 to prevent water from entering the dryer. The drying chamber 50 is also equipped with a PID temperature controller and a K-type thermocouple for temperature control and overheat protection. The K-type thermocouple is inserted into the interior of the drying chamber 50 to provide real-time feedback on the internal temperature. The PID temperature controller is set to a working temperature of 90~100℃. It should be noted that, for safety, as with existing technologies, overheat protection can be provided by setting an overheat protection switch.

[0043] Preferably, the horizontal transmission mechanism 51 is a mesh belt conveyor, which facilitates the filtration of liquid.

[0044] Preferably, the frame 1 is further provided with a high-pressure cleaning assembly 12, which is located above the mesh belt conveyor and is used to remove impurities from the material before drying by high-pressure spraying. The high-pressure cleaning assembly 12 includes nozzles installed on the frame 1 and pipes connected to the nozzles. External cleaning liquid is transported to the pipes by a high-pressure water pump and sprayed out through the nozzles to clean the surface of the material.

[0045] The high-pressure water pump is preferably a DP-100 type high-pressure water pump with a rated flow rate of 10L / min and a head of 80m. The nozzles include three fan-shaped atomizing nozzles with a spray angle of 90° and an orifice diameter of 0.5mm. They are installed horizontally above the conveyor belt perpendicular to the material conveying direction, with an installation height of 150mm from the surface of the belt. The rated working pressure of the nozzles is 8bar, and the working pressure range is 4-12kg. This allows the high-pressure water to impact the material surface vertically in the form of a high-speed atomized jet, thereby effectively removing residual shell fragments, mud, and mucus from the surface of the shellfish.

[0046] Preferably, the drying mechanism 5 is located between the vibration separation mechanism 8 and the heating box 2, thereby reducing the floor space and achieving the compactness of the device.
