Description

Technical Field

[0001] The utility model relates to the field of aquatic feed, in particular to a device for cooling aquatic feed after expansion. Background Art

[0002] Aquatic feed refers to feed specially provided for aquatic animal breeding. There are many kinds of feed. According to the processing form, it can be divided into powdered feed, soft pellet feed, hard pellet feed and expanded feed; according to the breeding stage, it can be divided into fry crushed feed, breeding feed and fish feed; according to the breeding species, it can be divided into carp feed, grass carp feed, shrimp feed, etc.; according to the physical properties of feed, it can be divided into sinking feed and floating feed. In addition, according to the feeding species, it can also be divided into fish feed, shrimp feed and crab feed; according to the characteristics of feed, it can be divided into compound feed, concentrated feed and premixed feed.

[0003] The raw materials for aquatic feed production are mainly composed of fish meal, grain raw materials and oils, and fish meal and grain raw materials often account for more than 50% of the feed cost. In addition to the main raw materials, enzymes and trace elements are also added to aquatic feed to enhance the palatability and nutrition of the feed.

[0004] When aquatic feed is pelletized, its raw materials will undergo physical treatment and then enter the pelletizer for pelleting and puffing. The pelleting and puffing process can change the physical properties of the feed, improve its stability and digestibility in water, and the puffed feed particles need to be cooled to reduce their temperature and make them easier to store and transport. The cooled feed particles will also be screened to remove unqualified particles to ensure the quality of the feed.

[0005] With respect to the above-mentioned related technologies, the inventors found that the feed particles after granulation and puffing are generally sent to a conveyor belt and cooled with a blowing fan, but the feed particles are generally clumped or piled on the conveyor belt. The blowing fan can only cool the external feed, which is inconvenient to cool the feed comprehensively, thereby reducing the cooling efficiency of the feed particles. In order to ensure that the feed is fully cooled, the existing processing method is often to lengthen the conveyor belt structure and add a blowing fan, which not only increases the production cost, but also affects the efficiency of subsequent feed screening and packaging. Utility Model Content

[0006] The main technical problem solved by the utility model is to provide a device for cooling aquatic feed after puffing, so as to prevent feed particles from agglomerating or piling up, improve the cooling efficiency of feed particles, reduce production costs, and improve the efficiency of subsequent feed screening and packaging.

[0007] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide an aquatic feed post-expansion cooling device, comprising: a conveying mechanism, one end of the conveying mechanism is connected to a material receiving plate assembly, and the other end is connected to a U-shaped material guide plate, and a plurality of blowing assemblies are installed at intervals on the top of the conveying mechanism, and the blowing assemblies include two symmetrically installed U-shaped frames, the U-shaped frames are installed on the top of the conveying mechanism, and a blowing fan is installed between the tops of the U-shaped frames, and a plurality of inclined guide partition plates 1 are installed at intervals on the inner top wall of one of the U-shaped frames, and a plurality of inclined guide partition plates 2 are installed at intervals on the inner top wall of the other U-shaped frame;

[0008] The first flow guide dividing plate and the second flow guide dividing plate are respectively arranged opposite to each other, and the second flow guide dividing plate and the first flow guide dividing plate are respectively arranged alternately;

[0009] The top two sides of the conveying mechanism are respectively connected with limit baffle assemblies, and a gas flow area is formed between the limit baffle assemblies.

[0010] By adopting the above technical scheme, the receiving plate assembly transfers the puffed feed particles to the conveying mechanism. When the conveying mechanism is about to convey it to the blowing assembly, the guide dividing plate 1 breaks up the clumped or piled feed so that the blowing fan can blow and cool the feed comprehensively. Then the feed passes through the guide dividing plate 2 again. Since the guide dividing plate 2 and the guide dividing plate 1 are staggered respectively, the feed particles can be broken up again, thereby comprehensively cooling the feed particles. In addition, a gas flow interval is formed between the limit baffle assemblies, which effectively concentrates the cold air blown out by the blowing fan on the top of the conveying mechanism, thereby improving the blowing and cooling effect of the blowing fan.

[0011] In a preferred example, the utility model can be further configured as follows: the material receiving plate assembly includes a U-shaped material receiving plate that is inclined, the lower end of the U-shaped material receiving plate is arranged close to the conveying mechanism, support arms are respectively installed on both sides of the bottom of the U-shaped material receiving plate, and the support arms are connected to the conveying mechanism, and a plurality of V-shaped guide blocks 1 are installed at intervals on the inner side of the U-shaped material receiving plate, and a plurality of V-shaped guide blocks 2 are arranged below one side of the V-shaped guide block 1, the V-shaped guide blocks 2 are respectively staggered with the V-shaped guide block 1, and the opening ends of the V-shaped guide block 1 and the V-shaped guide block 2 are respectively arranged close to the conveying mechanism.

[0012] By adopting the above technical solution, the feed particles expanded in the pellet mill are received and transmitted through the U-shaped receiving plate. Since the U-shaped receiving plate is inclined, the received feed passes through the V-shaped guide block 1 first and then passes through the V-shaped guide block 2 again, thereby preventing the feed from sticking together.

[0013] In a preferred example, the utility model can be further configured as follows: the conveying mechanism includes a mounting frame, a conveying mesh belt is provided on the inner side of the mounting frame, chains are respectively connected to both sides of the conveying mesh belt, the chains are respectively located on the opposite side of the limit baffle assembly, the inner two ends of the conveying mesh belt are respectively connected to driving rollers, sprockets are respectively installed at both ends of the driving rollers, the sprockets are respectively meshed with chains, a motor is connected to the mounting frame, and the output shaft of the motor is connected to one of the driving rollers.

[0014] By adopting the above technical solution, the motor drives one of the driving rollers to rotate, and the other driving roller is rotated under the action of the chain and the sprocket, so that the conveyor belt conveys the transmitted feed particles. Since there are certain pores on the conveyor belt, the cooling efficiency of the feed can be improved.

[0015] In a preferred example, the utility model can be further configured as follows: the limit baffle assembly includes a cross bar, the bottom of the cross bar is connected to a side plate, and the bottom of the side plate is arranged close to the conveyor belt.

[0016] By adopting the above technical solution, the side plates isolate the cold air blown out by the blowing fan, so that most of the cold air is concentrated between the side plates, thereby improving the cooling effect of the blowing fan on the feed.

[0017] In a preferred example, the utility model can be further configured as follows: a waste collecting plate is installed on the inner side of the mounting frame, a plurality of collecting hoppers with conical cross-sections are arranged at intervals at the bottom of the waste collecting plate, and collecting boxes are placed under the collecting hoppers respectively.

[0018] By adopting the above technical solution, when the conveyor belt is conveying feed, a certain amount of feed powder will fall from the surface of part of the feed, and the powder will fall into the collecting box along the collecting hopper for recycling, thereby improving the environmental protection and energy-saving effect of the equipment.

[0019] In a preferred example, the present invention can be further configured as follows: the U-shaped material guide plate is arranged obliquely, and the lower end of the U-shaped material guide plate is gradually tightened inward.

[0020] By adopting the above technical solution, the lower end of the U-shaped guide plate facilitates the transfer of the cooled feed to the screening machine for centralized screening.

[0021] In summary, the utility model includes at least one of the following beneficial technical effects of the post-expansion cooling device for aquatic feed:

[0022] 1. When the conveying mechanism is about to convey the feed to the blowing component, the guide dividing plate 1 will break up the clumped or piled feed so that the blowing fan can blow and cool the feed comprehensively. Then the feed passes through the guide dividing plate 2 again. Since the guide dividing plate 2 and the guide dividing plate 1 are staggered, the feed particles can be broken up again, thereby comprehensively cooling the feed particles and improving its cooling efficiency.

[0023] 2. The feed pellets puffed by the pellet mill are received and transmitted through the U-shaped receiving plate. Since the U-shaped receiving plate is tilted, the received feed first passes through the V-shaped guide block 1, and then passes through the V-shaped guide block 2 again, thereby preventing the feed from sticking together. Moreover, since the V-shaped guide block 2 and the V-shaped guide block 1 are staggered, the feed is further prevented from agglomerating.

[0024] 3. When the fan is blowing, the side plates isolate the cold air blown out by the fan, so that most of the cold air is concentrated in the gas flow area between the side plates, thereby improving the cooling effect of the fan on the feed. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0036] It should be noted that these drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0037] Reference Figure 1-4, is a post-expansion cooling device for aquatic feed disclosed in the utility model, comprising: a conveying mechanism 10, the conveying mechanism 10 comprises a mounting frame 11, a conveying mesh belt 12 is arranged on the inner side of the mounting frame 11, chains 13 are connected to both sides of the conveying mesh belt 12, the chains 13 are respectively located on the opposite side of the limit baffle assembly 50, driving rollers 14 are connected to the inner ends of the conveying mesh belt 12, sprockets 15 are respectively installed at both ends of the driving roller 14, and the sprockets 15 are respectively meshed and connected with the chains 13, a motor 16 is connected to the mounting frame 11, and the output shaft of the motor 16 is connected to one of the driving rollers 14, and one end of the conveying mechanism 10 is connected to The receiving plate assembly 20 is connected to a U-shaped guide plate 3 at the other end. The U-shaped guide plate 3 is tilted, and the lower end of the U-shaped guide plate 3 is gradually tightened inward. A plurality of blowing assemblies 40 are installed at intervals on the top of the conveying mechanism 10. The blowing assembly 40 includes two symmetrically installed U-shaped frames 41. The U-shaped frames 41 are installed on the top of the conveying mechanism 10. A blowing fan 42 is installed between the tops of the U-shaped frames 41. A plurality of tilted guide partition plates 1 43 are installed at intervals on the inner top wall of one of the U-shaped frames 41. A plurality of tilted guide partition plates 2 44 are installed at intervals on the inner top wall of the other U-shaped frame 41. The guide partition plate 1 The guide partition plate 43 is opposite to the guide partition plate 2 44, and the guide partition plate 2 44 is staggered with the guide partition plate 1 43. The top two sides of the conveying mechanism 10 are respectively connected to the limit baffle assembly 50, and a gas flow interval is formed between the limit baffle assembly 50. The limit baffle assembly 50 includes a cross bar 51, and the bottom of the cross bar 51 is connected to a side plate 52. The bottom of the side plate 52 is arranged close to the conveying mesh belt 12; the side plate 52 is preferably made of acrylic or plastic. When the motor 16 drives one of the driving rollers 14 to rotate, the other driving roller 14 is rotated by the cooperation of the chain 13 and the sprocket 15, so that the conveying mesh belt 12 is opposite to the conveying mesh belt 12. The transported feed particles are transported, and then the feed particles preferentially pass through the guide partition plate 1 43, whose inclination angle breaks up the clumped or piled feed so that the blowing fan 42 can blow and cool the feed comprehensively. Then the feed passes through the guide partition plate 2 44 again, and because the guide partition plate 2 44 and the guide partition plate 1 43 are staggered, other areas of the feed particles are broken up again, thereby improving the cooling efficiency of the feed. At the same time, when the blowing fan 42 blows, the side plate 52 isolates the cold air blown out by the blowing fan 42, so that most of the cold air is concentrated to flow between the side plates 52, thereby improving the cooling effect of the blowing fan 42 on the feed.

[0038] The receiving plate assembly 20 includes a U-shaped receiving plate 21 which is arranged obliquely. The lower end of the U-shaped receiving plate 21 is arranged close to the conveying mechanism 10. Support arms 22 are respectively installed on both sides of the bottom of the U-shaped receiving plate 21. The support arms 22 are connected to the conveying mechanism 10. A plurality of V-shaped guide blocks 23 are installed at intervals on the inner side of the U-shaped receiving plate 21. A plurality of V-shaped guide blocks 24 are arranged below one side of the V-shaped guide block 23. The V-shaped guide blocks 24 and the V-shaped guide blocks 23 are arranged alternately. The V-shaped guide blocks 23 and the V-shaped guide blocks 24 are arranged alternately. The open ends of the feed are respectively arranged close to the conveying mechanism 10; the support arm 22 is connected to the mounting frame 11, and the horizontal distance between the V-shaped guide block 1 23 and the V-shaped guide block 24 is 20cm-55cm. The pelletizer expands the feed and transmits it through the U-shaped receiving plate 21. Since the U-shaped receiving plate 21 is inclined, the received feed passes through the V-shaped guide block 1 23 first, and since the V-shaped guide block 24 and the V-shaped guide block 1 23 are staggered respectively, they are then broken up by passing through the V-shaped guide block 24 again, thereby preventing the feed from sticking together.

[0039] A waste collecting plate 17 is installed on the inner side of the mounting frame 11, and a plurality of collecting hoppers 18 with conical cross-sections are arranged at intervals at the bottom of the waste collecting plate 17, and collecting boxes 19 are placed under the collecting hoppers 18 respectively; when the conveyor mesh belt 12 is conveying feed, a certain amount of feed powder will fall from the surface of part of the feed, and the powder will fall into the collecting hopper 18 along the gaps of the conveyor mesh belt 12, and then slide along the inclined surface of its inner wall into the collecting box 19 for recycling.

[0040] The implementation principle of this embodiment is as follows: after the pelletizer processes and expands the feed particles, the feed particles are received and transmitted through the U-shaped receiving plate 21, and the partially agglomerated feed particles are initially dispersed through the V-shaped guide block 23 and the V-shaped guide block 23 along the inclination angle, and then transmitted to the conveyor mesh belt 12. At this time, when the motor 16 drives one of the driving rollers 14 to rotate, the other driving roller 14 is rotated through the cooperation of the chain 13 and the sprocket 15, so that the conveyor mesh belt 12 conveys the transmitted feed particles, and then the feed particles preferentially pass through the guide dividing plate 43, and the agglomerated or spherical feed particles are dispersed through the inclination angle. The accumulated feed is broken up, and the blowing fan 42 cools the feed by blowing air. Then the feed passes through the guide partition plate 44 again. Since the guide partition plate 44 and the guide partition plate 1 43 are arranged alternately, the guide partition plate 44 breaks up other areas of the feed again and cools the feed during the conveying process of the conveyor belt 12. At the same time, the feed passes through the blowing component 40 for multiple blowing cooling. In addition, when the blowing fan 42 blows air, the side plate 52 isolates the cold air blown out by the blowing fan 42, so that most of the cold air is concentrated to flow between the side plates 52, thereby improving the cooling effect of the blowing fan 42 on the feed.

[0041] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
