Technical Field
[0001] This utility model relates to the technical field of black soldier fly processing equipment, and in particular to a novel cooling hopper device. Background Technology
[0002] Black soldier flies can effectively decompose kitchen waste and convert it into high-value biomass such as oil and protein. Using black soldier flies to treat kitchen waste is an environmentally friendly and economically beneficial method. During the black soldier fly breeding process, the insect excrement can be used as biological organic fertilizer. Black soldier fly larvae, due to their high protein content, can be directly fed to poultry and aquatic products or processed into feed additives to replace traditional fishmeal.
[0003] During the processing of black soldier fly larvae, the larvae need to be dried to obtain dried black soldier fly larvae. The dried black soldier fly larvae contain impurities such as broken larvae, frass, and down, so they need to be screened again.
[0004] The Chinese utility model patent with patent number ZL202420582271.1 and patent name, entitled "Anti-clogging Hopper", discloses the following technical solution: An anti-clogging hopper includes a support frame, a hopper body, a vibrating plate, a vibrating element, and a connecting mechanism. The hopper body is vertically mounted on the support frame. The top of the hopper body has a feed inlet, and the bottom of the hopper body is open. The vibrating plate is connected to the bottom of the hopper body through the connecting mechanism. The bottom of the side wall of the hopper body near the lower end of the vibrating plate has a discharge outlet. The vibrating element is mounted on the bottom wall of the vibrating plate and is used to drive the vibrating plate to vibrate. The vibrating element can be a vibrating motor, which is installed on the bottom wall of the vibrating plate.
[0005] When the aforementioned anti-clogging hopper is in operation, the material is fed in from the inlet at the top of the hopper body, falls onto the vibrating plate and slides down the inclined vibrating plate, and is finally discharged from the outlet. During use, the vibrating components are started simultaneously, causing the vibrating plate to vibrate up and down slightly, thereby making the material slide down more smoothly and improving the problem of easy clogging when the hopper discharges material.
[0006] It should be noted that the aforementioned anti-clogging hopper still has defects. Specifically, the dried black soldier fly larvae after drying by the drying equipment still have a high temperature. During the process of feeding the dried black soldier fly larvae to the screening device through the hopper device, since the anti-clogging hopper does not have a cooling function, it cannot accelerate the cooling of the dried black soldier fly larvae with a high drying temperature, and therefore cannot be used for black soldier fly processing. Utility Model Content
[0007] The purpose of this invention is to provide a novel cooling hopper device to address the shortcomings of existing technologies. This novel cooling hopper device has a novel structural design and a cooling function, which can cool the dried black soldier fly larvae during the feeding process.
[0008] To achieve the above objectives, this utility model is implemented through the following technical solution.
[0009] A novel cooling hopper device includes a fixed support frame, with a vertically arranged main hopper mounted on the upper end of the fixed support frame. The main hopper has a vertically penetrating hopper cavity inside, with the upper opening of the hopper cavity serving as the inlet and the lower opening of the hopper cavity serving as the outlet.
[0010] The lower end of the main hopper is equipped with a vibrating receiving groove, which has a receiving cavity that opens forward. The lower end of the main hopper extends into the receiving cavity of the vibrating receiving groove. A straight vibrator is installed on the lower end of the fixed support frame of the vibrating receiving groove, and the bottom of the vibrating receiving groove is connected to the drive end of the straight vibrator.
[0011] The main hopper is surrounded by a surrounding plate, which is spaced apart from the main hopper, and an airflow cavity is formed between the surrounding plate and the main hopper; the side wall of the main hopper has a side wall mesh that connects the airflow cavity and the inner cavity of the hopper.
[0012] The enclosure is equipped with several spaced-out air intake channels that open outwards. Each air intake channel is connected to an airflow chamber, and each air intake channel is equipped with an inward-flowing fan.
[0013] Wherein, an air outlet gap with a downward opening and communicating with the airflow cavity is formed between the lower edge of the enclosure and the lower end of the main hopper;
[0014] When the new cooling hopper device is working, the airflow sent downward through the air outlet gap blows toward the vibrating receiving trough.
[0015] The main hopper is provided with a conical section, and the part of the inner cavity of the hopper corresponding to the conical section is wider at the top and narrower at the bottom. The surrounding plate is fitted around the conical section of the main hopper.
[0016] The vibrating receiving trough includes a bottom plate, which is connected to the drive end of the linear vibrator.
[0017] The vibrating receiving trough also includes an upwardly protruding rim that extends sequentially along the left edge, rear edge, and right edge of the base plate. The base plate and the rim are an integral structure, and the receiving cavity is formed by the base plate and the rim together.
[0018] The main hopper, the vibrating receiving trough, and the surrounding plate are all made of stainless steel.
[0019] Compared with existing technologies, this utility model has the following advantages: Specifically, during the operation of the novel cooling hopper device of this utility model, dried black soldier fly larvae, dried to a high temperature by a drying device, are poured into the inner cavity of the hopper through the feed inlet. The dried black soldier fly larvae in the inner cavity are discharged from the discharge outlet at the lower end of the inner cavity and enter the receiving cavity of the vibrating receiving trough. During this process, the fans in each air inlet channel send air into the airflow cavity. The cold air entering the airflow cavity enters the inner cavity of the hopper through the side wall mesh of the main hopper side wall, thereby cooling the dried black soldier fly larvae in the inner cavity, achieving the purpose of cooling the dried black soldier fly larvae. Therefore, the novel cooling hopper device of this utility model has the advantages of novel structural design and cooling function, that is, it can cool the dried black soldier fly larvae during the feeding process.

Detailed Implementation
[0027] The present invention will now be described in conjunction with specific embodiments.
[0028] Example 1, as Figures 1 to 4 As shown, a novel cooling hopper device includes a fixed support frame 1. The upper end of the fixed support frame 1 is equipped with a vertically arranged main hopper 2. The main hopper 2 has a vertically penetrating hopper cavity 21 inside. The upper opening of the hopper cavity 21 is a feed inlet, and the lower opening of the hopper cavity 21 is a discharge outlet.
[0029] Among them, such as Figure 1 , Figure 3 as well as Figure 4 As shown, a vibrating receiving groove 3 is installed on the lower end of the main hopper 2. The vibrating receiving groove 3 is formed with a receiving cavity 31 that opens to the front. The lower end of the main hopper 2 extends into the receiving cavity 31 of the vibrating receiving groove 3. A straight vibrator 4 is installed on the lower end of the fixed support frame 1. The bottom of the vibrating receiving groove 3 is connected to the driving end of the straight vibrator 4.
[0030] Furthermore, such as Figures 1 to 4 As shown, a surrounding plate 5 is fitted around the main hopper 2. The surrounding plate 5 is arranged at intervals with the main hopper 2, and an airflow cavity 6 is formed between the surrounding plate 5 and the main hopper 2. The side wall of the main hopper 2 is provided with a side wall mesh 22 that connects the airflow cavity 6 and the inner cavity 21 of the hopper.
[0031] Furthermore, such as Figure 1 , Figure 3 as well as Figure 4 As shown, the enclosure 5 is provided with several air inlet channels 51 arranged at intervals and opening outwards respectively. Each air inlet channel 51 is connected to the airflow cavity 6, and each air inlet channel 51 is equipped with an inward air supply fan 7.
[0032] It should be explained that the main hopper 2, the vibrating receiving trough 3, and the surrounding plate 5 in this embodiment are all made of stainless steel.
[0033] It should be noted that the novel cooling hopper device in this embodiment is equipped with a controller, and the vibrator 4 and each fan 7 are electrically connected to the controller; during operation, the controller controls the operation of the vibrator 4 and each fan 7 respectively.
[0034] In the process of processing black soldier fly larvae, the novel cooling hopper device of this embodiment is applied. The dried black soldier fly larvae, which have been dried by the drying equipment and have a high temperature, are poured into the inner cavity 21 of the hopper through the feed inlet. The dried black soldier fly larvae in the inner cavity 21 are discharged from the discharge outlet at the lower opening of the inner cavity 21 and enter the receiving cavity 31 of the vibrating receiving trough 3. During this process, the fans 7 in each air inlet channel 51 are started and blow air into the airflow cavity 6. The cold air entering the airflow cavity 6 enters the inner cavity 21 of the hopper through the side wall mesh 22 of the side wall of the main hopper 2, thereby cooling the dried black soldier fly larvae in the inner cavity 21 to achieve the purpose of cooling the dried black soldier fly larvae.
[0035] As the vibrator 4 drives the vibrating receiving trough 3 to vibrate, the dried black soldier fly larvae that fall into the receiving chamber 31 of the vibrating receiving trough 3 are discharged from the front opening of the receiving chamber 31. The above-mentioned vibration action can make the dried black soldier fly larvae evenly distributed on the subsequent conveyor belt or screening device.
[0036] It should be further pointed out that, since the main hopper 2 of this embodiment is made of stainless steel, the dried black soldier fly larvae in the inner cavity 21 of the hopper will conduct heat to the main hopper 2. When the fan 7 sends cold air into the airflow cavity 6, the cold air flow will cool the side wall of the main hopper 2, thereby cooling the dried black soldier fly larvae in the inner cavity 21 of the hopper.
[0037] In summary, the novel cooling hopper device of this embodiment has the advantages of novel structural design and cooling function, which means it can cool the dried black soldier fly larvae during the feeding process.
[0038] Example 2, as Figure 4 As shown, the difference between this embodiment 2 and embodiment 1 is that: an air outlet gap 8 with a downward opening and connected to the airflow cavity 6 is formed between the lower edge of the enclosure 5 and the lower end of the main hopper 2.
[0039] It should be noted that when the new cooling hopper device is working, the airflow sent downward through the air outlet gap 8 blows towards the vibrating receiving trough 3.
[0040] When the blower 7 delivers cold air into the airflow chamber 6, some of the cold air will be discharged from the air outlet gap 8. The cold air flow discharged through the air outlet gap 8 will further cool the dried black soldier fly larvae in the receiving chamber 31, thereby further improving the cooling effect of the dried black soldier fly larvae.
[0041] Example 3, as Figures 1 to 4 As shown, the difference between this embodiment 3 and embodiment 1 is that: the main hopper 2 is provided with a conical section 23, the part of the inner cavity 21 of the hopper corresponding to the conical section 23 is wide at the top and narrow at the bottom, and the surrounding plate 5 is fitted around the conical section 23 of the main hopper 2.
[0042] Example 4, as Figure 1 , Figure 3 as well as Figure 4 As shown, the difference between this embodiment four and embodiment one is that the vibrating receiving trough 3 includes a bottom plate 32, which is connected to the driving end of the straight vibrator 4.
[0043] Furthermore, the vibrating receiving trough 3 also includes a perimeter 33 that extends sequentially along the left edge, rear edge and right edge of the base plate 32 and protrudes upward. The base plate 32 and the perimeter 33 are an integral structure, and the receiving cavity 31 is formed by the base plate 32 and the perimeter 33 together.
[0044] The function of the rim 33 is to ensure that the dried black soldier fly larvae discharged from the outlet at the lower end of the inner cavity 21 of the hopper fall accurately into the receiving cavity 31, and to ensure that the dried black soldier fly larvae are sent out from the front end of the receiving cavity 31.
[0045] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
