DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings and examples, but they are not intended to limit the present invention.

[0027] Embodiment: A pickling device based on the arsenic removal method of Sargassum fusiformis, comprising a frame 1, as shown in the attached Figure 1 As shown, a top frame 2 is provided at the upper end of the frame 1, a cutting and unloading mechanism 3 is provided on the top frame 2, side brackets 4 are provided on both sides of the frame 1, a bearing seat 5 is provided on the side brackets 4, a cleaning drum bracket 6 is provided between the side brackets 4 on both sides, a shaft body 7 is provided on the side of the cleaning drum bracket 6, and the shaft body 7 is provided in the bearing seat 5; a drum-type cleaning mechanism 8 with a drain valve is provided in the cleaning drum bracket 6, and a heating pipe 9 is provided in the drum-type cleaning mechanism 8, as shown in the attached figure. Figure 5As shown, the drum-type cleaning mechanism 8 has an inner and outer double-drum structure, similar to the structure of a drum washing machine. The cleaning mechanism is divided into an inner and outer drum, and a motor at the bottom drives the inner drum to rotate. For easy observation, the outer drum is made of acrylic. However, because acrylic is polymerized from methyl methacrylate monomer (MMA) or extruded from acrylic pellets through an extruder, it has low elongation and is therefore prone to cracking and brittleness. Therefore, a bracket is provided on the outside of the drum-type cleaning mechanism as the main load-bearing part. The center of the outer drum is supported by a rubber ring for auxiliary support and sealing. The heating tube 9 is a U-shaped structure arranged in the drum. Dearsenication of Sargassum fusiformis requires immersion in a dearsenication solution at a certain temperature. The anisotropic heating tube is made of a high-temperature resistant stainless steel seamless tube with high-temperature resistance wires evenly distributed. The gaps are densely filled with crystalline magnesium oxide powder with excellent thermal conductivity and insulation properties. This structure is not only advanced, but also has high thermal efficiency and uniform heat generation. When current flows through the high-temperature resistance wire, the generated heat is diffused to the surface of the metal tube through the crystalline magnesium oxide powder and then transferred to the heated part or water, achieving the purpose of heating. The heterogeneous heating tube has high thermal efficiency, good mechanical strength, and good adaptability to harsh environments. The U-shaped electric heating tube can be used to heat various liquids and acids, bases, and salts, meeting the needs of this mechanism. A water supply mechanism 10 and a liquid supply mechanism 11 are provided within the frame 1. The water outlet pipe of the water supply mechanism 10 and the liquid outlet pipe of the liquid supply mechanism 11 are respectively aligned with the drum-type cleaning mechanism 8. The frame 1 is provided with a dumping mechanism 12, the swinging end of the dumping mechanism 12 is connected to the upper end of the cleaning drum bracket 6. A salt spreading mechanism 13 is provided at the upper end of the frame 1, above the drum-type cleaning mechanism 8. A pushing and pressing mechanism 14 is provided on one side of the frame 1, next to the displacement drum-type cleaning mechanism 8.

Before cutting, the seedling rope passes through the guide plate, then passes through the annular circular knife and the limiting channel, and finally is wound around the driving winding drum. The driving winding drum drives the seedling rope to move, and the sea lettuce is cut off by the annular circular knife and falls into the blanking assembly; the seedling rope with the sea lettuce part will be slightly thicker than the original seedling rope, so the diameter of the knife edge should be larger than the diameter of the seedling rope.

[0029] The blanking assembly 306 includes an electric push rod 307 arranged on the top frame 2, as shown in the attached Figure 3As shown, a push plate 308 is provided at the protruding end of the electric push rod 307, a pressure sensor 309 is provided on the top frame 2, a container 310 is provided on the pressure sensor 309, and the push plate 308 is arranged on one side of the container 310. The cut sea lettuce will fall into the container of the blanking component. A pressure sensor is provided at the bottom of the container. When the weight of the sea lettuce in the container reaches a certain value, the electric push rod drives the push plate to move, and the sea lettuce in the container is pushed into the cylinder below. Through the quantitative feeding structure, the amount of sea lettuce in the cleaning cylinder can be effectively controlled, which is convenient for better cleaning.

[0030] The dumping mechanism 12 includes a screw support 121 vertically arranged on the inner side of the frame 1, as shown in the attached Figure 4 As shown, a screw motor 122 is provided at the bottom of the screw bracket 121, and a screw 123 is provided in the screw bracket 121. The protruding end of the screw motor 122 is connected to the screw 123 through a coupling, and a moving block 124 is provided on the screw 123. A slide rail 125 is provided on the screw bracket 121, and one side of the moving block 124 fits with the slide rail 125; one end of the moving block 124 is rotatably provided with a connecting rod 126, and the upper end of the cleaning cylinder bracket 6 is provided with a rod fixing seat 127, and a cross bar 128 is provided in the rod fixing seat 127. Both ends of the cross bar 128 are movably connected with the connecting rod 126. The screw motor drives the screw to rotate, so that the moving block moves, and the moving block drives the connecting rod to swing. Driven by the connecting rod, the drum cleaning mechanism tilts, and the sea cucumber is poured into the pushing and pressing mechanism.

[0031] The salt spreading mechanism 13 includes a salt spreading bracket 131 arranged at the upper end of the frame 1, as shown in the attached Figure 6 To the attached Figure 8 As shown, a salt spreading motor 132 is provided at the upper end of the salt spreading bracket 131, and a gear 133 is provided at the protruding end of the salt spreading motor 132. A salt box 134 is provided in the salt spreading bracket 131, and a feed port 135 is provided at the upper end of the salt box 134. A lifting shaft 136 is provided at the center of the salt box 134, and a rack 137 matched with the gear 133 is provided at the upper end of the lifting shaft 136. A quantitative chamber 138 is provided at the bottom of the salt box 134, and an upper sealing plate 139 and a lower sealing plate 140 are provided at the lower end of the lifting shaft 136. The upper sealing plate 139 cooperates with the upper opening of the quantitative chamber 138, and the lower sealing plate 140 cooperates with the lower opening of the quantitative chamber 138. In the salt spreading mechanism, in the initial state, the lower sealing plate engages with the lower opening of the metering chamber, allowing salt from the salt box to enter the metering chamber. The salt spreading motor then starts, driving the gear to rotate. The rack at the upper end of the lifting shaft engages with the gear, causing the lifting shaft to move downward. The upper sealing plate seals the upper opening of the metering chamber, while the lower sealing plate opens the lower opening of the metering chamber. The salt in the metering chamber falls into the barrel, effectively controlling the amount of salt spread through the quantitative salt addition mechanism. The bottom of the salt spreading bracket 131 has a funnel-shaped slope structure, which ensures that the sprinkled salt falls evenly on the seaweed.

The pouring mechanism pours the sea lettuce in the cleaning cylinder into the pickling cylinder. When the pickling cylinder moves to the bottom of the circular pressing plate, the circular pressing plate presses the sea lettuce in the pickling cylinder under the drive of the pressing push rod.
