Abstract
Description
Technical Field
[0001] This utility model relates to the field of protein insect processing technology, specifically to a protein insect screening device. Background Technology
[0002] During the black soldier fly breeding process, after the black soldier fly larvae have grown in the breeding box for a specified number of days, the black soldier fly larvae and feed residue are poured out of the breeding box. At this time, the black soldier fly larvae and feed residue are in a mixed state, and it is necessary to sieve the black soldier fly larvae and feed residue before transferring the black soldier fly larvae to the next breeding site.
[0003] During the screening process of planaria farming, food residue, due to its moisture content, easily clumps together, leading to the following problems with traditional screening devices: moist residue adheres to the screen surface, clogging the screen holes and reducing screening efficiency; accumulated residue affects the planaria's activity space and is difficult to remove completely; existing equipment mostly uses mechanical vibration or simple brushing, which cannot effectively solve the problem of adhesive clogging, especially for small screen holes where stubborn adhesion is more likely to form. In addition, frequent manual cleaning increases labor intensity and may cause mechanical damage to the planaria.
[0004] Therefore, a screening device for protein worms is proposed. Utility Model Content

[0026] like Figure 1-6As shown, the sieve device for protein worms includes a support frame 1, a controller 2, a collection box 3, a dust suction component 4, a high-pressure jet component 5, a sieve cylinder 6, a drive component 7, and a brush assembly 8. The sieve cylinder 6 is rotatably mounted on the support frame 1 via connecting frames 601 on both sides. Its cylinder diameter gradually increases axially, and the sieve aperture of the sieve cylinder 6 gradually increases along the material movement direction, achieving graded sieve separation of impurities. The drive component 7 is connected to the connecting frames 601 to drive the sieve cylinder 6 to rotate. Material mixed with protein worms and impurities can be loaded and unloaded through the positions of the connecting frames 601, allowing the support frame 1 to be rotated. The length of the screen cylinder 6 is adjustable to facilitate loading and unloading from the side; the high-pressure jet component 5 is located at the front of the screen cylinder 6 and is used to spray high-pressure hot air onto the surface of the screen cylinder 6; the brush assembly 8 is located inside the screen cylinder 6 and is tangent to the top of the inner wall of the cylinder; the dust suction component 4 is located at the rear of the screen cylinder 6 and is used to suck up impurities; the collection box 3 is located below the screen cylinder 6 and its interior is divided into an impurity collection chamber and a protein worm collection chamber by a partition 301; specifically, the controller 2 is electrically connected to the hot air blower 501, the air pump 404 and the motor 701 respectively, and is used to adjust the hot air temperature, the air pumping power and the screen cylinder rotation speed.
[0027] like Figure 1 and 5 As shown, the high-pressure jet component 5 includes a hot air blower 501, a connecting plate 502, a jet plate 503, and a high-pressure nozzle 504. The hot air blower 501 is fixed to the support frame 1 via the connecting plate 502. The jet plate 503 is arranged axially along the screening cylinder 6, and its surface is uniformly provided with multiple high-pressure nozzles 504. The jetting direction of the high-pressure nozzles 504 is towards the screen holes on the front side of the screening cylinder 6. Specifically, the high-pressure nozzles 504 can be flat-headed duckbill-shaped nozzles to achieve gas convergence, increase air pressure, and clean the blockage impurities under the action of backflushing. The power of the hot air blower 501 can be controlled by the controller 2 to control its temperature not to exceed 35°C, so as to avoid harming the protein worms. At the same time, since the blown air is located on the front side of the screening cylinder 6, the protein worms are located at the bottom of the screening cylinder 6 under the action of gravity. Therefore, the high-pressure hot air will not directly act on the protein worms and will not harm them. The length of the jet plate 503 is adapted to the length of the screening cylinder 6 to ensure the cleaning effect.
[0028] like Figure 2 and 6 As shown, the brush assembly 8 includes a connecting rod 801 and a brush plate 802. The connecting rod 801 passes through the hollow connecting frame 601 and is fixed to the support frame 1. The brush plate 802 is installed on the connecting rod 801, and its bristles are in close contact with the top of the inner wall of the screening cylinder 6. Specifically, the brush plate 802 can be fixed to the connecting rod 801 by bolts for easy replacement. The brushes of the brush plate 802 must be made of wear-resistant material to ensure its service life.
[0029] like Figure 2 and4 As shown, the dust collection component 4 includes a dust collection hood 401, a filter box 402, a filter screen 403, and an air pump 404. The dust collection hood 401 covers the upper middle side of the rear half of the screening cylinder 6, and its outlet is connected to the filter box 402 through a pipe. The filter screen 403 is located inside the filter box 402, and the air pump 404 is located at the outlet end of the filter box 402. Specifically, the filter screen 403 can be installed inside the filter box 402 by snap-fit or bolt fixing, which is convenient for disassembly, replacement, and cleaning. The bottom of the dust collection hood 401 has a through hole, and the air pump 404 can suck up and filter dust and impurities when it is working to avoid environmental pollution.
[0030] like Figure 2 and 3 As shown, the driving component 7 includes a motor 701, a first gear 702, and a second gear 703. The motor 701 is fixed to the support frame 1, and its output shaft is connected to the first gear 702. The second gear 703 is sleeved on the connecting frame 601 and meshes with the first gear 702. Specifically, the operation of the motor 701 can drive the first gear 702 to rotate. The meshing of the first gear 702 and the second gear 703 can drive the connecting frame 601 to rotate, thereby driving the screening cylinder 6 to rotate. During the rotation, the screening of materials can be accelerated, and the materials are moved towards the outlet end during the rotation.
[0031] like Figure 2 As shown, the partition 301 of the collection box 3 is detachable and its partition position corresponds to the lower end of the discharge end of the screening cylinder 6. The protein worm collection chamber is located below the end with the largest diameter of the screening cylinder 6. Specifically, during the screening process, impurities will continuously fall into the impurity collection chamber below. The protein worms have the largest diameter and can fall into the protein worm collection chamber below through the outlet end of the screening cylinder 6, thereby achieving the classification and collection of impurities and protein worms.
[0032] In summary: First, the material mixed with protein bugs and impurities enters the rotating screening cylinder 6 through the connecting frame 601. The motor 701 of the drive component 7 drives the first gear 702 and the second gear 703 to mesh, causing the screening cylinder 6 to rotate. During the screening process, the hot air blower 501 of the high-pressure jet component 5 generates high-pressure hot air not exceeding 35°C, which is sprayed onto the screen holes on the front side of the screening cylinder 6 through the high-pressure nozzles 504 on the jet plate 503, blowing off the clogging impurities and drying the damp residue. At the same time, the brushes fixed on the connecting rod 801... The brush plate 802 of component 8 continuously scrapes the top of the inner wall of the screening cylinder 6 to remove impurities that have not been blown off. The gradually increasing diameter and screen hole design of the screening cylinder 6 allow small particles of impurities to be preferentially screened into the impurity collection chamber of the collection box 3, while the planar worms fall into the planar worm collection chamber after moving to the maximum diameter end as the cylinder rotates. The dust suction component 4 on the rear side sucks up the dust through the dust suction hood 401, and after being purified by the filter screen 403 of the filter box 402, it is discharged by the air pump 404, ultimately achieving efficient separation and collection of planar worms and impurities, as well as environmental purification.
