Description

Technical Field

[0001] The present invention relates to the technical field of fish feed processing, and specifically provides a fish feed processing device and processing method with a fast feeding function. Background Art

[0002] When processing fish feed, the raw materials of fish feed are puffed by a fish feed processing device. During the puffing process, starch is fully gelatinized through high temperature and high pressure, so that the protein and fat structures are more easily digested, significantly improving the absorption rate of fish for nutrients. The puffed fish feed has buoyancy, and the floating feed is convenient for observing the feeding situation of fish, facilitating accurate adjustment of the feeding amount, and improving management efficiency.

[0003] When using a fish feed processing device to puff-process raw materials, the raw materials are first crushed, mixed, etc., and then the processed raw materials are put into the storage bin inside the processing device. The raw materials are sent into the puffing machine cavity through the storage bin. The pressure in the cavity rises to 3 - 10 MPa, and the temperature reaches 120 - 160 °C. The high temperature and high pressure fully gelatinize the starch and loosen the protein structure. At the same time, anti-nutritional factors and pathogenic microorganisms are inactivated. Under the rotation and extrusion of the twin screws, the raw materials are extruded. After the material is extruded through the die holes, the pressure drops instantly, and the internal moisture vaporizes and expands to form a porous structure, and then is cut into regular particles by a rotary cutter to complete the puffing process of fish feed.

[0004] In the existing fish feed processing device during the puffing process of raw materials, since the raw materials are heated at high temperature inside the puffing cavity, when the material is extruded through the die holes, due to the sudden drop in pressure, the internal moisture quickly vaporizes, generating a large amount of high-temperature steam. A large amount of heat generated during the high-temperature and high-pressure treatment is contained in these steams, which is directly discharged without being recovered, resulting in waste of resources. Summary of the Invention

[0019] Preferably, a second motor is fixed on the side of the storage bin, the output end of the second motor extends into the storage bin and is rotatably connected with the storage bin, and a feeding auger is fixed at the output end of the second motor, and the feeding auger extends into the feeding pipe.

[0020] A fish feed processing method with a fast feeding function includes the following steps:

[0021] S1: Pour the pulverized and mixed fish feed raw materials into the storage bin, and send the raw materials out through the feeding pipe;

[0022] S2: The raw materials enter the screw extrusion mechanism for heating, puffing and extrusion, and the extruded raw materials enter the cutting mechanism for cutting to obtain granular finished fish feed;

[0023] S3: When the finished fish feed is fed, the negative pressure member works to make steam enter the waste heat recovery coil to heat the water in the water storage tank, and under the action of the heat exchange member, heat the fish feed raw materials in the storage bin;

[0024] S4: When the negative pressure member works, the anti-sticking component works to scrape off the raw materials adhering to the inner wall of the storage bin;

[0025] S5: Continuously add raw materials into the storage bin until all the finished fish feed is processed.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. When discharging the finished fish feed, the present invention drives the driving gear to rotate by the operation of the first motor, causing the driven gear to rotate, so that the driving shaft drives the impeller to rotate, generating negative pressure inside the negative pressure housing. The steam is sucked into the guide pipe through the horn pipe, then enters the conveying pipe through the guide pipe, and finally enters the waste heat recovery coil pipe. The waste heat recovery coil pipe transfers the heat to the water inside the water storage tank to heat the water, realizing waste heat recovery, thus achieving the purpose of saving resources. The water heated by the steam inside the water storage tank is pumped into the heat exchange coil pipe by the extraction pump, and the heat is transferred through the heat exchange coil pipe to the inside of the storage bin, thereby realizing the preheating of the raw materials and the reuse of waste heat recovery, reducing waste of resources. By preheating the raw materials, the heat required to heat them to the puffing temperature after entering the screw extruder can be reduced, further reducing waste of resources;

[0028] 2. At the same time, the stirring shaft rotates to drive the second pulley to rotate. Under the action of the transmission belt, the first pulley drives the rotating shaft to rotate. When the rotating shaft rotates, the rotating shaft drives the connecting rod and the scraping strip to rotate. The raw materials attached to the inner wall of the storage bin can be scraped off by the scraping strip, thereby reducing the adhesion of the raw materials. During the heating process of the raw materials, the raw materials attached to the inner wall of the storage bin will form a caking phenomenon when heated, and the caking phenomenon will affect the heat conduction efficiency and the heat exchange efficiency of the heat exchange coil pipe. The water in the heat exchange coil pipe still maintains a relatively high temperature when it flows back to the inner wall of the water storage tank again. As the water temperature inside the water storage tank is gradually heated by the waste heat recovery coil pipe, and the heat released by the heat exchange coil pipe inside the storage bin is less, the temperature inside the water storage tank will continue to rise, resulting in the evaporation and gradual reduction of the water inside the water storage tank, affecting the water circulation heat exchange. By using the scraping strip, the raw materials attached to the inner wall of the storage bin can be reduced, avoiding the problem of low heat transfer efficiency caused by the hardening of the attached raw materials under the heating of the heat exchange coil pipe, thereby improving the heat exchange efficiency of the heat exchange coil pipe, reducing waste of resources, and reducing the problem of affecting the entire water circulation due to low heat exchange efficiency;

[0029] 3. At the same time, during the rotation of the connecting rod and the scraping strip, the connecting rod and the scraping strip can turn over the raw materials inside the storage bin, making the raw materials heat more evenly. The raw materials can fully absorb the heat inside the heat exchange coil pipe, further improving the heat exchange efficiency and reducing waste of resources. Moreover, the rotation of the connecting rod and the scraping strip can disperse the raw materials inside the storage bin, thereby avoiding the caking phenomenon after heating, making the raw materials heat evenly, and being more conducive to the subsequent puffing processing of fish feed.

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] Example 1

[0043] Please refer to Figures 1 to 7 , which is the first embodiment of the present invention, and provides a technical solution: a fish feed processing device with a fast feeding function, including a placement table 1, a storage bin 11 is fixed at the upper end of the placement table 1, a feed pipe 12 is fixed at the upper end of the storage bin 11, a feeding pipe 13 is fixed on the side of the storage bin 11, a screw extrusion mechanism 14 is installed on the side of the placement table 1, and the fish feed raw materials are heated and expanded by the screw extrusion mechanism 14 and finally extruded. A receiving pipe 16 is installed on the screw extrusion mechanism 14, and the receiving pipe 16 is located below the feeding pipe 13, so that the raw materials inside the storage bin 11 can fall into the receiving pipe 16. One end of the screw extrusion mechanism 14 away from the placement table 1 is installed with a cutting mechanism 15, and the raw materials extruded and expanded by the screw extrusion mechanism 14 can be cut by the cutting mechanism 15 to obtain granular finished fish feed. A finished product discharge pipe 17 is arranged at the lower end of the cutting mechanism 15, and a waste heat recovery component 2 is arranged between the finished product discharge pipe 17 and the placement table 1; an anti-sticking component 3 is arranged inside the storage bin 11;

[0044] The waste heat recovery component 2 includes a horn pipe 21 fixed to the upper end of the slitting mechanism 15. Through the horn pipe 21, the air intake range of the diversion pipe 22 can be increased, the dispersion range of the steam can be reduced, and it is more convenient to suck the steam into the interior of the diversion pipe 22 subsequently. A diversion pipe 22 is fixed to the horn pipe 21. The diversion pipe 22 is located on the side of the finished product discharge pipe 17 and will not affect the discharge of the finished fish feed. A barrier net is fixed inside the horn pipe 21, and the barrier net can prevent the finished fish feed from splashing into the interior of the horn pipe 21. One end of the diversion pipe 22 away from the horn pipe 21 is fixed with a negative pressure housing 23. A negative pressure component 26 is arranged on the negative pressure housing 23. By means of the negative pressure component 26, negative pressure is generated inside the negative pressure housing 23, and the steam can be sucked into the interior of the diversion pipe 22, then enter the conveying pipe 28 through the diversion pipe 22, and finally enter the waste heat recovery coil 25 to achieve waste heat recovery. A conveying pipe 28 is fixed to the side of the negative pressure housing 23 away from the diversion pipe 22. Heat insulation layers are arranged on the horn pipe 21, the diversion pipe 22, and the conveying pipe 28. Through the heat insulation layer, the heat loss of the steam during transportation can be reduced. A water storage tank 24 is fixed to the upper end of the placement table 1. A waste heat recovery coil 25 is fixed inside the water storage tank 24. The waste heat recovery coil 25 is made of copper pipe. The copper pipe has good thermal conductivity, enabling the steam temperature inside it to better heat the water in the tank. One end of the conveying pipe 28 away from the negative pressure housing 23 is fixedly connected to the waste heat recovery coil. Water is contained inside the water storage tank 24. The steam sucked into the interior of the diversion pipe 22 by the negative pressure component 26 enters the interior of the waste heat recovery coil 25 through the conveying pipe 28. The heat is transferred to the water through the waste heat recovery coil 25 to heat the water and achieve waste heat recovery, thereby achieving the purpose of saving resources. One end of the waste heat recovery coil 25 away from the conveying pipe 28 extends out of the water tank. A water receiving tank is fixed to the side of the placement table 1. The end of the waste heat recovery coil 25 extends into the interior of the water receiving tank. Through the water receiving tank, the condensed water inside the waste heat recovery coil 25 can be collected. A heat exchange component 27 is arranged inside the storage bin 11. The recovered heat can continuously heat the raw materials inside the storage bin 11 through the heat exchange component 27 to achieve preheating of the raw materials and realize the reuse of resources. By preheating the raw materials, the heat required to heat them to the puffing temperature after they enter the screw extruder can be reduced, further reducing the waste of resources.

[0045] When the negative pressure component 26 works, negative pressure is generated inside the negative pressure housing 23, sucking the steam into the diversion pipe 22 and then sending it into the heat exchange coil 271 through the conveying pipe 28, and heating the raw materials inside the storage bin 11 through the heat exchange component 27. At the same time, when the negative pressure component 26 works, it drives the anti-sticking component 3 to work and rotate.

[0046] A second motor 5 is fixed to the side of the storage bin 11. The output end of the second motor 5 extends into the interior of the storage bin 11 and is rotatably connected to the storage bin 11. A feeding auger 51 is fixed to the output end of the second motor 5. The feeding auger 51 extends into the interior of the blanking pipe 13. When feeding the raw materials inside the storage bin 11 into the receiving pipe 16, the second motor 5 is turned on. By driving the feeding auger 51 to rotate through the second motor 5, the raw materials inside the storage bin 11 can be quickly fed into the receiving pipe 16, realizing rapid blanking and reducing blockage.

[0047] The negative pressure member 26 includes a drive shaft 261 rotatably connected inside the negative pressure housing 23. An impeller 262 is fixed to the drive shaft 261. By rotating the impeller 262, a negative pressure is generated inside the negative pressure housing 23, thus facilitating the suction of steam into the diversion pipe 22.

[0048] A first motor 263 is fixed to the lower end of the placement table 1. The rotation speed of the first motor 263 is adjustable, facilitating adjustment according to actual needs to meet the requirements. The output end of the first motor 263 is fixed with a driving gear 264. One end of the drive shaft 261 extends out of the negative pressure housing 23 and is fixed with a driven gear 265 meshing with the driving gear 264. The number of teeth on the driven gear 265 is greater than the number of teeth on the driving gear 264. When the driving gear 264 drives the driven gear 265, the rotation speed of the driven gear 265 is less than that of the driving gear 264. When the first motor 263 operates to drive the driving gear 264 to rotate, the driven gear 265 rotates, thereby driving the drive shaft 261 to drive the impeller 262 to rotate, providing power for the rotation of the impeller 262.

[0049] The heat exchange member 27 includes a sandwich layer provided inside the storage bin 11. A heat exchange coil 271 is fixed inside the sandwich layer. The heat exchange coil 271 is made of copper pipe, and the copper pipe has good thermal conductivity, enabling the heat of the water inside the heat exchange coil 271 to better heat the raw materials inside the storage bin 11. One end of the heat exchange coil 271 is connected to the bottom of the water storage tank 24 in communication, and the other end is connected to the top of the water storage tank 24 in communication. A pumping pump 272 is fixed to the end of the heat exchange coil 271 connected to the bottom of the water storage tank 24. The water heated by the steam inside the water storage tank 24 is pumped into the heat exchange coil 271 through the pumping pump 272, and heat is transferred through the heat exchange coil 271 to transfer the heat to the inside of the storage bin 11, thereby realizing the heating of the raw materials and the reuse of waste heat recovery, reducing resource waste.

[0050] A flow disturbing plate 251 is fixed inside the waste heat recovery coil 25. When steam enters the waste heat recovery coil 25, the flow disturbing plate 251 can increase the flow path of the steam inside the heat exchange coil 271, thereby improving the efficiency of steam heat conversion and enabling the water inside the water storage tank 24 to fully absorb the heat in the steam.

[0051] During use, pour the fish feed raw materials into the interior of the storage bin 11. During processing, drive the feeding auger 51 through the second motor 5 to send the raw materials out through the feeding pipe 13. The rotation of the feeding auger 51 can achieve rapid feeding and reduce the blockage of the feeding pipe 13. The raw materials discharged from the feeding pipe 13 enter the interior of the receiving pipe 16 and finally enter the interior of the screw extrusion mechanism 14. The screw extrusion mechanism 14 heats, puffs, and extrudes the raw materials. The extruded raw materials enter the interior of the cutting mechanism 15. The cutting mechanism 15 can cut the raw materials puffed and extruded by the screw extrusion mechanism 14 to obtain granular finished fish feed. The finished fish feed is discharged through the finished product discharge pipe 17, and steam will float out when discharged. At this time, the first motor 263 works. The work of the first motor 263 drives the driving gear 264 to rotate, causing the driven gear 265 to rotate, so that the drive shaft 261 drives the impeller 262 to rotate, and can suck the steam in the horn pipe 21 into the interior of the diversion pipe 22, then enter the conveying pipe 28 through the diversion pipe 22, and finally enter the waste heat recovery coil 25. The waste heat recovery coil 25 transfers the heat to the water in the water storage tank 24 to heat the water, realizing waste heat recovery, so as to achieve the purpose of saving resources. The water heated by the steam in the water storage tank 24 is pumped into the interior of the heat exchange coil 271 through the extraction pump 272, and the heat is transferred through the heat exchange coil 271 to transfer the heat to the interior of the storage bin 11, thus realizing the preheating of the raw materials and the reuse of waste heat recovery, reducing resource waste. By preheating the raw materials, the heat required to heat them to the puffing temperature after entering the screw extruder can be reduced, further reducing resource waste.

[0052] Embodiment 2

[0053] Please refer to Figure 3 、 Figure 8 、 Figure 9 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that:

[0054] A stirring shaft 4 is rotatably connected to the upper end of the placing table 1. The stirring shaft 4 penetrates through the water storage tank 24 and is rotatably connected to the water storage tank 24. Stirring blades 41 are fixed on the stirring shaft 4. The rotation of the stirring shaft 4 drives the rotation of the stirring blades 41, so that the stirring agitates the water in the water storage tank 24, thereby enabling the water in the water storage tank 24 to be heated more evenly, which is more conducive to heating the raw materials in the storage bin 11. The lower end of the stirring shaft 4 penetrates through the placing table 1 and is fixed with a first bevel gear 42. The output end of the first motor 263 is fixed with a second bevel gear 43 meshing with the first bevel gear 42. The first motor 263 drives the second bevel gear 43 to rotate, thereby causing the first bevel gear 42 to rotate. The rotation of the first bevel gear 42 drives the second bevel gear 43 to rotate, causing the stirring shaft 4 to rotate, playing a transmission role.

[0055] During use, when the first motor 263 drives the impeller 262 to rotate, the second bevel gear 43 rotates following the output end of the first motor 263. The rotation of the second bevel gear 43 drives the first bevel gear 42 to rotate, causing the stirring shaft 4 to rotate. The rotation of the stirring shaft 4 drives the multiple stirring blades 41 to rotate. The rotation of the stirring blades 41 can stir the water inside the water storage tank 24, making the heating of the water inside the water storage tank 24 more uniform. Thus, the heating of the raw materials inside the storage bin 11 through the heat exchange coil 271 is more uniform, improving the utilization rate of waste heat recovery.

[0056] The remaining structure is the same as that of Embodiment 1.

[0057] Embodiment 3

[0058] Please refer to Figure 3 and Figure 10 This is the third embodiment of the present invention. The difference between this embodiment and the first and second embodiments is:

[0059] The anti-sticking component 3 includes a rotating shaft 31 rotatably connected inside the storage bin 11. A connecting rod 32 is fixed on the rotating shaft 31. A scraping strip 33 is arranged inside the storage bin 11. The scraping strip 33 is fixedly connected with the connecting rod 32. The scraping strip 33 is an elastic rubber strip. The scraping strip 33 made of elastic rubber can better fit with the inner wall of the storage bin 11. A transmission member 34 is arranged between the rotating shaft 31 and the stirring shaft 4. When the stirring shaft 4 rotates, the rotating shaft 31 can be driven to rotate in cooperation with the transmission member 34. The rotation of the rotating shaft 31 drives the connecting rod 32 and the scraping strip 33 to rotate. Since the scraping strip 33 fits with the inner wall of the storage bin 11, when the scraping strip 33 rotates following the rotating shaft 31, the raw materials attached to the inner wall of the storage bin 11 can be scraped off, thus reducing the adhesion of the raw materials. The attachments on the inner wall of the storage bin 11 may form a crust due to the heating of the heat exchange coil 271, and the crust phenomenon will affect the heat conduction efficiency and the heat exchange efficiency of the heat exchange coil 271. When the water in the heat exchange coil 271 flows back to the inner wall of the water storage tank 24 again, it still maintains a relatively high temperature. As the water temperature inside the water storage tank 24 is gradually heated by the waste heat recovery coil 25, and the heat released by the heat exchange coil 271 inside the storage bin 11 is less, the temperature inside the water storage tank 24 will continue to rise, causing the water inside the water storage tank 24 to evaporate and gradually decrease, affecting the water circulation heat exchange. By using the scraping strip 33, the raw materials attached to the inner wall of the storage bin 11 can be reduced, avoiding the problem of low heat transfer efficiency caused by the hardening of the attached raw materials under the heating of the heat exchange coil 271, thereby improving the heat exchange efficiency of the heat exchange coil 271. At the same time, during the rotation of the connecting rod 32 and the scraping strip 33, the raw materials inside the storage bin 11 can be turned over, making the raw materials heated more evenly and avoiding the caking phenomenon caused by uneven heating.

[0060] The transmission member 34 includes a pulley 1 341 fixed on the upper end of the rotating shaft 31, and a pulley 2 342 is fixed on the upper end of the stirring shaft 4. The pulley 1 341 and the pulley 2 342 are connected to each other through a transmission belt 343. When the stirring shaft 4 rotates, the pulley 2 342 is driven to rotate, and the transmission belt 343 is driven to rotate under the action of the pulley 2 342, so that the pulley 1 341 rotates, thereby driving the rotating shaft 31 to rotate, thereby playing a transmission role.

[0061] During use, when the stirring shaft 4 rotates, the second pulley 342 rotates accordingly, and under the action of the second pulley 342, the transmission belt 343 is driven to rotate, so that the first pulley 341 is driven to rotate, thereby driving the rotating shaft 31 to rotate. When the rotating shaft 31 rotates, the rotating shaft 31 rotates to drive the connecting rod 32 and the scraping bar 33 to rotate. The scraping bar 33 can scrape the raw materials attached to the inner wall of the storage bin 11, thereby reducing the adhesion of the raw materials. In the process of heating the raw materials, the raw materials attached to the inner wall of the storage bin 11 will form a scab due to the heat, and the scab phenomenon will affect the heat conduction efficiency and the heat exchange efficiency of the heat exchange coil 271. The water in the heat exchange coil 271 still maintains a relatively high temperature when it flows back to the inner wall of the water storage tank 24 again. As the water temperature inside the water storage tank 24 is recovered by the waste heat recovery coil 25 Gradually heated, while the heat exchange coil 271 releases less heat inside the storage bin 11, which will cause the temperature inside the water tank 24 to continue to rise, causing the water inside the water tank 24 to evaporate and gradually decrease, affecting the water circulation heat exchange, and the scraper bar 33 can reduce the raw materials attached to the inner wall of the storage bin 11, and avoid the attached raw materials from hardening under the heating of the heat exchange coil 271 and causing the problem of low heat transfer efficiency, thereby improving the heat exchange efficiency of the heat exchange coil 271 and reducing the problem of the impact of low heat exchange efficiency on the entire water circulation. At the same time, during the rotation of the connecting rod 32 and the scraper bar 33, the raw materials inside the storage bin 11 can be turned over, so that the raw materials are heated more evenly, avoiding the agglomeration phenomenon caused by uneven heating, and thus being more conducive to the subsequent puffing processing of fish feed.

[0062] The remaining structures are the same as those of embodiments 1 and 2.

[0063] The present application embodiment provides a fish feed processing method with a fast feeding function, comprising the following steps:
