Description

Technical Field

[0001] The utility model relates to a crushing and recycling device, in particular to a crab shell crushing and recycling device. Background Art

[0002] The crushing and recycling of crab shells is a way of resource recycling, which is very common especially in the food processing industry and scientific research fields. Crab shells are mainly composed of chitin, which is a natural polysaccharide with a wide range of uses. It can be used to produce chitosan, bioplastics, cosmetics, drug carriers, etc. For example, in the cosmetics and pharmaceutical industries, chitin can be used as a biodegradable material to manufacture films, bandages or other medical supplies.

[0003] Seafood processing plants will generate a large amount of crab shell waste after processing crabs. Restaurants, hotels and large banquet venues, etc. will also generate a large amount of crab shells when providing seafood dishes. Enterprises focusing on waste management and resource recycling can also include crab shells in their recycling plans and convert crab shells into useful resources. When crushing and recycling crab shells, the crab shells need to be dried to remove moisture, and then a special crusher is used to crush the crab shells into fine particles or powder for subsequent storage needs. However, the existing crab shell crushing and recycling devices directly put the recycled crab shell waste into a special crusher for crushing without drying the crab shells, resulting in affecting the utilization and storage of subsequent fine particles or powder of crab shells.

[0004] Therefore, it is necessary to design a crab shell crushing and recycling device to solve the above technical problems. Summary of the Utility Model

[0025] First, place the device at the designated working location. Then, put the pre-prepared crab shells in a container and place it beside the device. Next, start the heating tube 10 and the blower 11 through the controller 28. At this time, the heating tube 10 starts to continuously heat up, and the air inside the outer shell 2 gradually gets hot and warms up. At the same time, the fan blades of the blower 11 generate an air flow mechanically. This air flow forms a pressure difference inside the outer shell 2, helping the hot air around the heating tube 10 to be taken away from the heat source, so that the inside of the outer shell 2 is always filled with hot air. Subsequently, the staff first starts the first motor 3 and the second motor 13 through the controller 28, and then pours the crab shells into the inside of the outer shell 2 through the first hopper 7. At this time, the output shaft of the first motor 3 drives the rotating shaft 4 to rotate counterclockwise, and the rotating shaft 4 drives the wire mesh conveyor belt 6 to rotate counterclockwise. The output shaft of the second motor 13 drives the rolling rollers 14 and the gears 15 on it to rotate counterclockwise. At this time, the two gears 15 are engaged, that is, the rear rolling roller 14 and the gear 15 rotate counterclockwise, and the front rolling roller 14 and the gear 15 rotate clockwise. Also, because the baffle 8 is set in an inclined state, so at this time under the blocking action of the baffle 8, the crab shells poured into the inside of the outer shell 2 will fall on the wire mesh conveyor belt 6 along the baffle 8 and be conveyed from right to left by the wire mesh conveyor belt 6. Because there is still a certain amount of moisture attached to the recycled crab shells, so the crab shells come into contact with the hot air inside the outer shell 2 during the conveying process, and the hot air evaporates the moisture on the crab shells. At this time, because the outer shell 2 is partially closed, the rising water vapor will contact the top of the outer shell 2. When the water vapor condenses on the top of the outer shell 2 and reaches a certain degree, it will fall in the form of water droplets. Finally, the dried crab shells are conveyed to the second hopper 16. Also, because the second hopper 16 is set in an inclined state, so the crab shells fall into the gap between the two rolling rollers 14 through the second hopper 16. At this time, the two rolling rollers 14 rotating towards each other generate a compressive force and a shear force, that is, the two rolling rollers 14 rotate towards each other. When the crab shells enter the gap between the two rollers, the crab shells will be subjected to a compressive force and a shear force from both sides. This compressive force and shear force attempt to flatten the crab shells in the direction perpendicular to the rotation axis 4 of the rollers, causing the crab shells to break at the contact point between the rollers and be crushed into small pieces or powder. The small pieces or powder of the crushed crab shells fall on the filter plate 17 through the bottom opening of the protective box 12 under the action of their own gravity.

[0026] When the two rolling rollers 14 rotate towards each other, the receiving shafts 18 and pulleys 19 at the right ends of the two rolling rollers 14 rotate accordingly. At the same time, the lower pulley 19 rotates driven by the flat belt 20 on its same side, and the two vibrating blocks 21 rotate driven by the pulley 19 at the lower part on their same side. That is, when the front rolling roller 14 rotates clockwise by 90°, the front vibrating block 21 rotates by 90° driven by the front pulley 19. At this time, the bottom of the front vibrating block 21 protrudes downward and pushes the limiting plate 24 on its same side to move downward through the guide rod 23. The front spring 25 contracts, and the filter plate 17 and the front fixing column 22 both move downward. When the front rolling roller 14 continues to rotate clockwise to 180°, the front vibrating block 21 rotates by 180° driven by the front pulley 19. At this time, the front vibrating block 21 resets and drives the limiting plate 24 on its same side to move upward through the guide rod 23 to the reset state. The front spring 25 resets, and the filter plate 17 and the front fixing column 22 both move upward. Similarly, when the rear rolling roller 14 rotates counterclockwise by 90°, it drives the rear pulley 19 and the vibrating block 21 to rotate by 90°. At this time, the rear vibrating block 21 protrudes downward and pushes the limiting plate 24 on its same side to move downward through the guide rod 23. The rear spring 25 contracts, and the filter plate 17 and the rear fixing column 22 both move downward. When the rear rolling roller 14 continues to rotate counterclockwise to 180°, the rear vibrating block 21 rotates by 180° driven by the rear pulley 19. At this time, the rear vibrating block 21 resets and drives the limiting plate 24 on its same side to move upward through the guide rod 23 to the reset state. The rear spring 25 resets, and the filter plate 17 and the rear fixing column 22 both move upward. At this time, under the simultaneous repeated pushing and resetting actions of the vibrating blocks 21 on the front and rear sides, the filter plate 17 is driven to move upward and downward, that is, the filter plate 17 is always in a vibrating state.

[0027] Since the filter plate 17 is set in an inclined state, that is, the filter plate 17 is in a state of being lower on the left and higher on the right, under the jitter action of the filter plate 17, small pieces of crab shells on the filter plate 17 fall into the second collection box 27, and the crab shell powder on the filter plate 17 directly falls into the first collection box 26 at its bottom, that is, the sorting of the crushed crab shell contents is realized. When both the first collection box 26 and the second collection box 27 are filled with the crushed crab shell contents, the staff can directly pull them out through the handles on them, and then pour the crab shell contents in the first collection box 26 and the second collection box 27 to the storage location. Subsequently, the empty first collection box 26 and the second collection box 27 can be put back to the initial position. When a part of the water droplets accumulates at the bottom inside the outer shell 2 and has fluidity, since the bottom of the outer shell 2 is in a state of being higher on the left and lower on the right, the water droplets flow from left to right and flow out through the water outlet pipe at the right bottom of the outer shell 2. If it is necessary to pause or stop the crushing and recycling of crab shells, the first motor 3, the second motor 13 and the fan 11 can be turned off through the controller 28. If it is necessary to crush the crab shells again, the above actions can be repeated.

[0028] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
