Abstract
Description
Technical Field
[0001] This utility model relates to the field of harmless treatment of dead animals, and in particular to a refining device for harmless treatment of dead animals. Background Technology
[0002] Currently, with the continuous expansion of breeding scale, the disposal of diseased and dead animals (livestock and poultry) is becoming increasingly prominent. Harmless disposal methods for diseased and dead animals include high-temperature methods, which extract the fat from the animal carcass through high-temperature refining. Typically, refining equipment is needed to fully extract the animal fat. During high-temperature refining, the stirring mechanism agitates the animal carcass (which may be pre-crushed) to improve the refining effect. Simultaneously, the stirring mechanism also functions like a screw conveyor, circulating the animal carcass within the refining equipment. In existing technologies, the heating module is usually located on the outer surface of the refining equipment. Due to the relatively large internal dimensions of the refining equipment, uneven heating may occur, affecting the refining effect of the animal fat. Furthermore, the circulation time of some large animal carcasses within the refining equipment is relatively short, and they are prone to jamming during movement or discharge under the action of the stirring mechanism; therefore, further improvements are needed.

For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] like Figure 1 , Figure 2As shown, an embodiment of this utility model provides a refining device for the harmless treatment of diseased and dead animals, including a refining tank 1 and a refining and stirring mechanism disposed inside the refining tank 1. The refining tank 1 is relatively sealed internally. The top of the refining tank 1 is equipped with an air inlet, an air outlet, an observation port, a feeding port, and a maintenance manhole, which may be connected to other equipment or sealed during the animal fat refining process. The bottom of the refining tank 1 is equipped with a discharge port for discharging the remaining animal carcasses after the animal fat refining is completed; this port is also sealed during the refining process.
[0028] In this embodiment, the refining and stirring mechanism includes a stirring shaft 2, stirring blades 3, and an oil guide pipe 4. It serves to agitate, transport, and heat the animal carcass, ensuring thorough heating for the extraction of animal fat. The stirring shaft 2 extends to the outside of the refining tank 1 at both ends and is connected to a motor via a transmission assembly. The motor drives its rotation, and bearings are installed at the refining tank 1 to support its rotation. Multiple stirring blades 3 are arranged along the axial direction of the stirring shaft 2, with their roots fixedly connected to the shaft and rotating synchronously. Furthermore, the stirring blades 3 are angled relative to the centerline of the stirring shaft 2, allowing them to propel the animal carcass forward and agitate it thoroughly.
[0029] The oil guide pipe 4 is used to introduce high-temperature oil to heat the animal carcass and extract animal fat. Compared to the oil guide pipe 4 being set around the outside of the refining tank 1, in this embodiment the oil guide pipe 4 is set inside the refining tank 1 and close to the center line of the stirring shaft 2. Therefore, during the stirring process of the stirring shaft 2 and the stirring blade 3, the agitated animal carcass can directly and fully contact the oil guide pipe 4, so that the high-temperature oil inside the oil guide pipe 4 can heat the animal carcass more evenly and fully to extract animal fat.
[0030] In a preferred embodiment, three oil guide pipes 4 are provided. The first end of each oil guide pipe 4 is connected to the inside of the first end of the stirring shaft 2, and the second end of each oil guide pipe 4 is connected to the inside of the second end of the stirring shaft 2. Simultaneously, the first end of the stirring shaft 2 extending outside the refining tank 1 is provided with an oil inlet, and the second end extending outside the refining tank 1 is provided with an oil outlet. High-temperature oil is introduced into the first end of the stirring shaft 2 through the oil inlet and enters the oil guide pipe 4, then enters the second end of the stirring shaft 2 and is discharged from the oil outlet. After being reheated, it returns to the first end of the stirring shaft 2, achieving a circulation process.
[0031] In a preferred embodiment, the interior of the stirring shaft 2 also allows high-temperature oil to pass through, meaning the high-temperature oil can be directly transported from the first end to the second end of the stirring shaft 2, so that the animal carcass near the stirring shaft 2 is heated by the high-temperature oil inside the stirring shaft 2. Therefore, there are a total of four branches for the high-temperature oil, three of which are three oil guide pipes 4, and the fourth branch is the stirring shaft 2, achieving the purpose of fully heating the animal carcass during the stirring process.
[0032] In a preferred embodiment, the three oil guide pipes 4 are rotationally symmetrically distributed with respect to the centerline of the stirring shaft 2 to further improve heating uniformity. Simultaneously, each oil guide pipe 4 is arranged in a spiral shape to accommodate the rotating transport of the animal carcass during stirring, allowing for more thorough contact with the carcass.
[0033] In a preferred embodiment, two sets of refining and stirring mechanisms are arranged in parallel within the refining tank 1, with opposite conveying directions. A transfer assembly is provided between the end of the first set of refining and stirring mechanisms and the beginning of the second set, as well as between the end of the second set and the beginning of the first set. Each transfer assembly includes a transfer frame 5 and a feeding plate 6. The transfer frame 5 is fixedly connected to the stirring shaft 2 of either the first or second set of refining and stirring mechanisms and rotates synchronously with the stirring shaft 2. The feeding plate 6 is fixedly connected to the transfer frame 5. Therefore, as the stirring shaft 2 rotates continuously, the feeding plate 6 also rotates continuously, feeding the animal carcass conveyed to the end of the first set of refining and stirring mechanisms to the beginning of the second set, and then conveying it in the opposite direction; or feeding the animal carcass conveyed to the end of the second set of refining and stirring mechanisms to the beginning of the first set, continuously circulating to heat and refine animal fats. When the size of the refining equipment is limited, this method can extend the journey of the animal carcass, i.e. the refining process, to achieve the goal of fully refining animal fat.
[0034] In this embodiment, the discharge port is located between the first end of the first refining and stirring mechanism and the tail end of the second refining and stirring mechanism, or between the first end of the second refining and stirring mechanism and the tail end of the first refining and stirring mechanism. Meanwhile, as... Figure 3 As shown, a discharge mechanism is also provided at the discharge port. Compared with the valve method, the discharge mechanism can better avoid discharge jamming.
[0035] Specifically, in this embodiment, the discharge mechanism includes a control plate 7 and a control rod 8 connected to the control plate 7. The control plate 7 is sized to match the discharge port, and when it moves to the position of the discharge port, it can close the discharge port, preventing animal carcasses in the refining tank 1 from falling out of the discharge port. The first end of the control rod 8 is integrally formed with the control plate 7, or is detachably connected, such as by a threaded connection. The second end of the control rod 8 is connected to the top of the refining tank 1 and can be raised and lowered relative to the refining tank 1, thereby adjusting the position of the control plate 7.
[0036] Therefore, during the refining process of animal fat, the control plate 7 can be kept in the position of closing the discharge port, allowing the animal carcass to circulate within the refining tank 1. After the refining of the animal fat is completed, the control plate 7 is moved upward by the control lever 8, opening the discharge port. The animal carcass circulating within the refining tank 1 will gradually move to the discharge port and fall out. If the discharge port becomes stuck, the control plate 7 can be moved downward again by the control lever 8, allowing the control plate 7 to contact the stuck animal carcass and press it downwards towards the discharge port, thus assisting the animal carcass to fall smoothly from the discharge port. After completion, the control plate 7 can be raised again by the control lever 8 to reopen the discharge port and continue discharging the remaining animal carcasses. Compared to valve settings, this method improves the smoothness of the refining equipment's discharge, thereby enhancing the reliability of the entire harmless treatment process.
[0037] In this embodiment, the control lever 8 is operated manually. A handwheel 9 is provided at the second end of the control lever 8 for easy hand operation. Simultaneously, a connecting cylinder 10 is provided at the top of the refining tank 1. The control lever 8 passes through the connecting cylinder 10, which has a threaded hole. A locking bolt 11 is inserted to lock the control lever 8, keeping the control plate 7 in the corresponding position. It should be noted that the connecting cylinder 10 has a certain length in this embodiment to ensure accurate downward pressure of the handwheel 9 by the operator, preventing deviations that could prevent the control plate 7 from entering the discharge port.
[0038] In summary, the refining equipment for the harmless treatment of dead animals provided in this embodiment, through the setting and coordination of the refining stirring mechanism and the discharge mechanism in the refining tank 1, ensures the circulation, thorough turning and heating of animal carcasses during the refining of animal fat in the refining tank 1, thereby improving the efficiency and quality of animal fat refining. At the same time, it ensures the smooth discharge of residual animal carcasses, thus improving the reliability of the refining equipment during operation.
[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0040] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
