Description

Technical Field

[0001] This invention belongs to the field of shrimp feed production technology, specifically relating to an enzymatic raw material screening device for shrimp feed production. Background Technology

[0002] Enzymatic hydrolysis is an important technique in shrimp feed production. It breaks down large protein molecules into smaller peptides, thereby improving the digestibility and nutritional value of the feed.

[0003] For example, adding fish peptides and proteases to replace fish meal can improve the growth performance of Litopenaeus vannamei and have a positive impact on digestive indicators and intestinal structure.

[0004] In existing aquaculture processes, the use of enzymatically hydrolyzed soybean meal to replace part of the fishmeal can increase the crude protein and crude fat content of shrimp muscle, while significantly reducing the malondialdehyde (MDA) content in shrimp serum. This indicates that enzymatically hydrolyzed soybean meal has the potential to improve the health of shrimp. In addition, the addition of enzymatically hydrolyzed soybean meal can significantly alter the shrimp's resistance to Vibrio and the spatiotemporal expression of its immune-related genes. When the addition amount reaches 4.5%, farmed Litopenaeus vannamei can obtain the best resistance to Vibrio.

[0005] Therefore, as can be seen from the above, the application of enzymatic hydrolysis technology in shrimp feed helps maintain good growth performance and stress resistance of shrimp. However, during the production and processing of raw materials, solid impurities such as dust, plant residues, metal fragments, and plastic particles may be mixed in. They may also be exposed to humid or improper storage conditions, and the feed may be contaminated by mold and bacteria, leading to mold and spoilage.

[0006] Therefore, before enzymatic hydrolysis of raw materials, it is necessary to remove impurities from the raw materials in a timely and efficient manner to avoid affecting the enzymatic hydrolysis and subsequent use. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an enzymatic raw material screening device for shrimp feed production.

[0008] The technical solution adopted to solve the above-mentioned technical problems is: an enzymatic hydrolysis raw material screening device for shrimp feed production, including a silo and a screening platform. An ash collection bin is installed on the inner wall of the silo, and a pneumatic vibrator is installed on the inner wall of the ash collection bin. The top of the ash collection bin has mounting holes for installing screens inside. A fixed support is installed on the top of the screening platform, and a conveyor belt is installed on the bottom of the screening platform. Multiple strip-shaped through holes are spaced apart on the top of the screening platform. Multiple first linear guide rail modules and multiple second linear guide rail modules are alternately installed on the two inner sides of the fixed support. The moving ends of two directly opposite first linear guide rail modules are jointly mounted on a first mounting frame. A third linear guide rail module is mounted on the side of the first mounting frame, and a crusher is installed on the moving end of the third linear guide rail module. The structure comprises a second mounting bracket on the moving ends of two opposing second linear guide rail modules. A fourth linear guide rail module is mounted on the side of the second mounting bracket, and a cleaning mechanism is mounted on the moving end of the fourth linear guide rail module. Multiple crossbeams located between the first and second linear guide rail modules are mounted on the inner side of the fixed bracket, and a visual recognition device is mounted on the side of each crossbeam. This design utilizes the precise movement and smooth motion of the linear guide rails to allow the crushing and cleaning mechanisms to move quickly and be precisely positioned at designated locations, improving screening accuracy. Furthermore, the staggered arrangement of the linear guide rails ensures that raw materials, when transported by conveyor belt, pass through the crushing and cleaning mechanisms sequentially. Combined with visual recognition technology, this enhances the screening effect.

[0009] Furthermore, the crushing mechanism includes a first right-angle plate, which is mounted on the moving end of the third linear guide module. A first electric cylinder is mounted on the inner side of the first right-angle plate. The first electric cylinder extends to the outside of the bottom of the first right-angle plate and is mounted on a second right-angle plate. A glue storage cylinder is mounted on the outer side of the second right-angle plate. An electric heating rod is installed inside the glue storage cylinder. A limit frame is mounted on the inner side of the second right-angle plate. A glue tube is slidably mounted inside the limit frame. A spring is provided on the outer surface of the glue tube. A top block is mounted on the side of the glue tube. A first motor is mounted at the bottom end of the outer side of the second right-angle plate. The output end of the first motor passes through the second right-angle plate and is mounted on an eccentric wheel. The top of the first right-angle plate is opposite to the second right-angle plate. A fifth linear guide module is installed on one side. A mounting plate is installed on the moving end of the fifth linear guide module. A first gear is mounted on the fixed-axis rotating shaft on the inner side of the mounting plate. A second motor is installed on the outer side of the mounting plate. The moving end of the second motor extends to the inner side of the mounting plate and is equipped with a second gear. A connecting rod is installed at the center of the sides of the first and second gears. A gripper is installed at the bottom end of the connecting rod. A connecting rod hinged to the connecting rod is mounted on the fixed-axis rotating inner side of the mounting plate. Through this scheme, the gripper's movement grips locked solid impurities or large pieces of raw material. Combined with the vibration of the hose, large pieces of raw material can be crushed, and materials gripped along with solid impurities can be knocked off the gripper, reducing material loss.

[0010] Furthermore, the impurity removal mechanism includes a third right-angle plate, on the inner side of which a second electric cylinder is mounted. A fixing frame is mounted at the bottom of the second electric cylinder, and a suction tube is embedded in the bottom surface of the fixing frame. An air collecting block is mounted on the side of the fixing frame. Through this scheme, combined with the use of an external air pump, which is connected to the air collecting block and the suction tube, airflow is used to suck away impurities, achieving the purpose of impurity removal.

[0011] Furthermore, the side of the hopper is connected to a feeding port facing the top of the ash collection hopper. The top surface of the ash collection hopper is inclined. The feeding port creates a material discharge space. When the raw material falls to the top surface of the ash collection hopper, the presence of the inclined surface, combined with the angle of the inclined surface, allows the raw material to stay in place. When the pneumatic vibrator is working, the slope of the inclined surface allows the raw material to fall more smoothly.

[0012] Furthermore, the glue storage cylinder is connected to the glue tube and the inside of the glue storage cylinder is filled with hot melt glue. The side of the eccentric wheel is in contact with the bottom surface of the top block. The use of hot melt glue, by utilizing the viscosity of hot melt glue and the physical state of hot melt glue at low temperature, forms a solid glue block with a certain strength and viscosity. When the glue tube performs vibration, it can capture solid impurities and achieve the purpose of removing fixed impurities from the raw materials.

[0013] Furthermore, the top end of the spring is connected to the outer surface of the rubber tube, and the bottom end of the spring is connected to the inner bottom surface of the limiting frame. By installing the spring in the above manner, the up-and-down vibration of the rubber tube is achieved by the elastic force of the spring.

[0014] Furthermore, the first gear meshes with the second gear, and the inner side of the gripper is provided with multiple protrusions. Through the above scheme, when the motor is activated, the two gears can rotate, thereby driving the connecting rod to move. When the gripper moves, the protrusions allow the gripper to better clamp the raw material or solid impurities.

[0015] Furthermore, the mounting plate has an assembly hole on its side facing the adhesive tube. The assembly hole provides space to install a pipe for connecting to an external air pump. Similarly, the airflow generated by the air pump removes the solidified adhesive block formed at the opening of the adhesive tube and cools the hot melt adhesive flowing out of the adhesive tube, thus accelerating the solidification of the hot melt adhesive.

[0016] Furthermore, the screening platform is provided with an inclined surface located between the hopper and the conveyor belt, and the side of the crossbeam on which the vision recognition device is installed is also an inclined surface. The inclined surface on the screening platform is designed to allow the raw materials to fall smoothly, and the inclined surface on the crossbeam allows the installed vision recognition device to have a better angle to monitor the raw materials being transported on the conveyor belt.

[0017] The beneficial effects of the present invention are as follows: (1) The present invention uses a crushing mechanism and a cleaning mechanism combined with a visual recognition device to identify impurities. After the impurities are identified, the crushing mechanism performs an action to pick up and crush the impurities. Combined with the use of hot melt adhesive, the impurities can be captured and removed from the raw materials to achieve the effect of screening impurities. (2) The present invention uses a clamping mechanism composed of gears, connecting rods and claws, combined with a vibrating rubber tube, and combined with a visual recognition device, it can also pick up large pieces of raw materials. Combined with the action of the claws and the vibration of the rubber tube, it can crush large pieces of raw materials so that the particle size of the raw materials can meet the requirements. (3) The present invention uses a component set on the second right angle plate, combined with hot melt adhesive in the rubber storage tube. By heating the hot melt adhesive, it can flow and, during the up and down vibration of the rubber tube, allow the hot melt adhesive to flow to the opening of the rubber tube and form a solid rubber block under the action of gravity. The characteristics of hot melt adhesive are used to capture fixed impurities. Attached Figure Description

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] like Figures 1 to 3 As shown in this embodiment, an enzymatic raw material screening device for shrimp feed production includes a silo 1 and a screening platform 2. An ash collection bin 3 is installed on the inner wall of the silo 1, and a pneumatic vibrator 4 is installed on the inner wall of the ash collection bin 3. The top of the ash collection bin 3 has an installation hole for installing a screen 5 inside. The side of the silo 1 is connected to a feeding port facing the top of the ash collection bin 3. The top surface of the ash collection bin 3 is inclined. By setting the angle of the inclined surface, after the raw material is fed into the feeding port and falls on the top of the ash collection bin 3, most of the raw material can stay on the screen 5. When the pneumatic vibrator 4 is working, the ash collection bin 3 is vibrated, and the raw material is initially screened by the screen 5, so that the dust can fall into the ash collection bin 3. At the same time, the raw material that has passed the initial screening can fall smoothly and enter the conveyor belt 7.

[0035] like Figure 3 and Figure 4 As shown, a fixed bracket 6 is installed on the top of the screening platform 2, and a conveyor belt 7 is installed on the bottom of the screening platform 2. Multiple strip-shaped through holes 8 are spaced apart on the top of the screening platform 2. Multiple first linear guide rail modules 9 and multiple second linear guide rail modules 10 are installed alternately on the two inner sides of the fixed bracket 6. The staggered arrangement of the linear guide rail modules, combined with the following description, allows the crushing mechanism and the impurity removal mechanism to alternately perform actions above the conveyor belt to screen the raw materials.

[0036] like Figure 2 , Figure 3 and Figure 4As shown, two opposing first linear guide rail modules 9 are mounted on a first mounting bracket 11 at their moving ends. A third linear guide rail module 12 is mounted on the side of the first mounting bracket 11, and a crushing mechanism is mounted on the moving end of the third linear guide rail module 12. Two opposing second linear guide rail modules 10 are mounted on a second mounting bracket 13 at their moving ends. A fourth linear guide rail module 14 is mounted on the side of the second mounting bracket 13, and a crushing mechanism is mounted on the moving end of the fourth linear guide rail module 14. The impurity removal mechanism has multiple crossbeams 39 installed on the inner side of the fixed bracket 6 between the first linear guide module 9 and the second linear guide module 10. A vision recognition device 40 is installed on the side of the crossbeam 39. The screening platform 2 is provided with an inclined surface between the hopper 1 and the conveyor belt 7. The inclined surface is designed to allow the raw materials to slide smoothly onto the conveyor belt 7. The side of the crossbeam 39 where the vision recognition device 40 is installed is an inclined surface. The inclined surface provides the vision recognition device 40 with a better shooting angle to observe the raw materials being conveyed on the conveyor belt 7.

[0037] like Figures 5 to 9 As shown, the crushing mechanism includes a first right-angle plate 15, which is mounted on the moving end of the third linear guide module 12. A first electric cylinder 16 is mounted on the inner side of the first right-angle plate 15. The first electric cylinder 16 extends to the outside of the bottom of the first right-angle plate 15 and is mounted on a second right-angle plate 17. A glue storage cylinder 18 is mounted on the outer side of the second right-angle plate 17. An electric heating rod 19 is installed inside the glue storage cylinder 18. A limit frame 20 is mounted on the inner side of the second right-angle plate 17. A glue tube 21 is slidably mounted inside the limit frame 20. A spring 22 is provided on the outer surface, a top block 23 is installed on the side of the tube 21, a glue storage cylinder 18 is connected to the tube 21 and the inside of the glue storage cylinder 18 is filled with hot melt glue, the side of the eccentric wheel 25 is in contact with the bottom surface of the top block 23, the top of the spring 22 is connected to the outer surface of the tube 21, and the bottom of the spring 22 is connected to the inner bottom surface of the limiting frame 20. By using the arrangement of the top and bottom of the spring 22, when the eccentric wheel 25 moves, the tube 21 can vibrate up and down, and the vibration action can achieve the purpose of crushing and promoting the flow of hot melt glue.

[0038] like Figures 7 to 10As shown, a first motor 24 is installed at the bottom of the outer side of the second right-angle plate 17. The output end of the first motor 24 passes through the second right-angle plate 17 and is equipped with an eccentric wheel 25. A fifth linear guide module 26 is installed on the top side of the first right-angle plate 15 opposite to the second right-angle plate 17. The linear guide module allows the movement of the hose 21 to cover a wider range during the up-and-down vibration of the hose 21 by moving the mounting plate 27, thereby improving the crushing effect and reducing the loss of raw materials. The moving end of the fifth linear guide module 26 is equipped with the mounting plate 27. A first gear 28 is installed on the fixed-axis rotating shaft on the inner side of the mounting plate 27. A second motor 29 is installed on the outer side of the mounting plate 27. The movable end of the machine 29 extends to the inner side of the mounting plate 27 and is equipped with a second gear 30. A connecting rod 31 is installed at the center of the side of the first gear 28 and the second gear 30. A gripper 32 is installed at the bottom end of the connecting rod 31. A connecting rod 33, which is hinged to the connecting rod 31, is mounted on the inner side of the mounting plate 27. The first gear 28 and the second gear 30 are meshed. The inner side of the gripper 32 is provided with multiple protrusions. The protrusions are designed to better grip the raw materials. The side of the mounting plate 27 is provided with an assembly hole facing the glue tube 21. The assembly hole provides installation space for installing the air tube. The air tube is connected to an external air pump. The airflow suction is used to suck away the hot melt adhesive with solid impurities and to cool the hot melt adhesive.

[0039] like Figures 12 to 13 As shown, the impurity removal mechanism includes a third right-angle plate 34, a second electric cylinder 35 is installed on the inner side of the third right-angle plate 34, a fixed frame 36 is installed at the bottom of the second electric cylinder 35, a suction tube 37 is embedded in the bottom surface of the fixed frame 36, and an air collecting block 38 is installed on the side of the fixed frame 36. By connecting the suction tube 37 and the air collecting block 38, and in conjunction with the use of an external air pump, the impurities can be removed.

[0040] The working principle of this embodiment is as follows: During screening, raw materials such as soybean meal are fed into the hopper 1 through the feeding port on the hopper 1. The raw materials will fall onto the top inclined surface of the ash collection hopper 3. At this time, the pneumatic vibrator 4 is activated. Through the action of the pneumatic vibrator 4, the ash collection hopper 3 will vibrate as a whole. With the presence of the screen 5, the raw materials at the top of the inclined surface will be screened out of dust by vibration and smoothly fed onto the inclined surface set on the screening platform 2. Guided by the inclined surface, they will fall into the strip-shaped through hole 8 and be transported by the conveyor belt 7. During the transportation process, the visual recognition device 40 will identify the impurities in the raw materials. When the crushing mechanism and the impurity removal mechanism are in operation, the conveyor belt 7 will temporarily stop working.

[0041] When large pieces of raw material or metal impurities are identified, the crushing mechanism moves to the top of the corresponding strip-shaped through hole 8 with the cooperation of the third linear guide module 12 and the moving end of the first linear guide module 9. Under the action of the first electric cylinder 16, the gripper 32 descends. Under the combined action of the first gear 28, the second gear 30, the connecting rod 31, and the connecting rod 33, the large pieces of raw material or metal impurities are picked up. If the raw material is large, the first motor 24 starts and drives the eccentric wheel 25 to rotate. The eccentric wheel 25 drives the rubber tube 21 to vibrate up and down to crush the large pieces of raw material. Combined with the pressure generated by the gripper 32, the large pieces of raw material are crushed. When the raw material contains metal impurities, after the gripper 32 picks up the metal impurities, the solid rubber block formed at the bottom of the rubber tube 21 sticks the metal impurities to it or allows the metal impurities to be embedded in the rubber block.

[0042] Therefore, since the interior of the glue storage cylinder 18 is filled with hot melt adhesive, and an electric heating rod 19 is installed inside the glue storage cylinder 18, the hot melt adhesive in the glue storage cylinder 18 is heated by the electric heating rod 19, making the hot melt adhesive in a flowable state. The flow of the molten adhesive is slow, so when the glue tube 21 vibrates up and down, it also helps the hot melt adhesive to flow. When the hot melt adhesive flows to the opening of the glue tube 21, under the action of gravity, the hot melt adhesive will form a solid glue block at the opening. Furthermore, the mounting plate 27 has an assembly hole on its side facing the glue tube 21, in which an air pipe connected to an external air pump is installed. Through the suction of the external air pump, the glue tube 21... The airflow generated at the bottom not only allows the solid glue block to gradually solidify and harden through rapid cooling, but also, when the suction is sufficient, the hot melt glue inside the glue tube 21 is still in a flowable state, sucking away the solid glue block. As a result, glue blocks with viscosity and a certain degree of hardness can be continuously output at the opening of the glue tube 21 to capture metal impurities. Furthermore, it can also be used to capture other solid impurities. In addition, by setting the suction tube 37 and the air collecting block 38 on the impurity removal mechanism, and by connecting to an external air pump, the impurities in the raw material are sucked away from the raw material by the suction of the airflow after the crushing mechanism is activated, thus achieving the screening effect.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
