Description

Technical Field

[0001] This utility model relates to the field of animal experimental technology, and in particular to a waste disposal device for animal experiments. Background Technology

[0002] Animal experiments are an important tool in research in life sciences, medicine, and pharmacy. They play an irreplaceable role in promoting scientific progress and protecting human and animal health. Among these, animal experiment waste treatment devices are used to avoid environmental and human harm caused by improper waste disposal.

[0003] According to the public announcement (CN210450262U), a device for the harmless recycling of laboratory animal carcasses and waste is disclosed. This technology discloses a technical solution that includes "a recycling box, which is a cylindrical structure without an upper surface. The upper surface of the recycling box has a locking hole on the right end, and a locking post is engaged in the locking hole. The locking post is integrally set at the lower right end of the fixed cover. This solution has the technical effect of dividing the upper cover into a fixed cover and a movable cover, ensuring that the recycling box is easy to open while having good sealing performance, preventing the leakage of gas and liquid, achieving harmless recycling, and not polluting the environment. The recycling box of this utility model can separate the solid and liquid in the recycled materials, achieving the purpose of separate processing, facilitating subsequent processing, and having strong practicality."

[0004] However, in the aforementioned comparative documents, the recycling bins do not perform any additional processing when recycling waste. The waste is supported by the skeleton, resulting in low utilization of storage space. Furthermore, the traditional subsequent processing involves cutting and crushing, which requires transporting the waste temporarily stored in the recycling bins to the cutting and crushing area for processing. This process is cumbersome and inefficient.

[0005] Therefore, this utility model provides a waste disposal device for animal experiments. Summary of the Invention

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a waste treatment device for animal experiments.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: an animal experimental waste treatment device, including a shell, a bracket fixedly connected to the upper part of the shell, a motor fixedly connected to the upper part of the shell, a first driving bevel gear fixedly connected to the output end of the motor, a first rotating shaft rotatably connected inside the bracket, a second rotating sleeve rotatably connected inside the bracket, a first driven bevel gear fixedly connected to the upper end of the first rotating shaft, the surface of the first driven bevel gear meshing with the first driving bevel gear, a second driven bevel gear fixedly connected to the upper end of the second rotating sleeve, the surface of the second driven bevel gear meshing with the first driving bevel gear, a first blade fixedly connected to the lower part of the first rotating shaft, and a second blade fixedly connected to the lower part of the second rotating sleeve.

[0008] Furthermore, an opening and closing door is rotatably connected to the upper end of the outer shell, and a spring is fixedly connected to the lower end of the opening and closing door. The fixed end of the spring is fixedly connected to the outer shell. This arrangement allows waste gas to enter the outer shell and closes to prevent odor from escaping.

[0009] Furthermore, a drive shaft is fixedly connected to the lower end of the first rotating shaft, and a second driving bevel gear is fixedly connected to the end of the drive shaft, so that the second driving bevel gear can rotate inside the housing.

[0010] Furthermore, the inner part of the housing is rotatably connected to a third driven bevel gear, and the surface of the second driving bevel gear meshes with the third driven bevel gear, so that the third driven bevel gear rotates inside the housing.

[0011] Furthermore, a material conveying pipe is fixedly connected to the side end of the outer shell, and a material conveying roller is rotatably connected inside the material conveying pipe. The side end of the material conveying roller is fixedly connected to a third driven bevel gear. This arrangement allows the crushed waste to be transported to the storage location using the material conveying roller.

[0012] Furthermore, a separation screen cylinder is fixedly connected inside the material conveying pipe. The surface of the separation screen cylinder has several holes, which enables solid-liquid separation of waste gas within the separation screen cylinder.

[0013] Furthermore, the material conveying pipe is fixedly connected to an inclined block, and the material conveying pipe is fixedly connected to a liquid outlet pipe, so that the separated liquid can be discharged through the liquid outlet pipe.

[0014] The technical effects of adopting the above further solution are:

[0015] This invention provides a waste disposal device for animal experiments. It has the following beneficial effects:

[0016] The first and second blades rotate in both directions, allowing waste to be temporarily stored and then immediately crushed to reduce its volume and processing steps. The dual-blade bidirectional crushing creates cross-shearing and bidirectional tearing forces, making it easier to cut bones and tendony meat, resulting in higher crushing efficiency.

[0017] By using a separating screen cylinder in conjunction with the compression of waste materials during transport by conveying rollers, the separated liquid can flow down the inclined block and be discharged through the liquid outlet pipe, thus avoiding liquid accumulation inside and achieving a better solid-liquid separation effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 - Figure 4As shown: This utility model provides a technical solution: an animal experimental waste treatment device, including a shell 1, a support 2 fixedly connected to the upper part of the shell 1, a motor 3 fixedly connected to the upper part of the shell 1 to prevent violent shaking when the motor 3 rotates, a first driving bevel gear 4 fixedly connected to the output end of the motor 3, a first rotating shaft 5 rotatably connected inside the support 2, the inner circumference of the support 2 being equal to the outer circumference of the first rotating shaft 5, a second rotating sleeve 6 rotatably connected inside the support 2, the inner circumference of the support 2 being equal to the outer circumference of the second rotating sleeve 6, a first driven bevel gear 7 fixedly connected to the upper end of the first rotating shaft 5, the surface of the first driven bevel gear 7 meshing with the first driving bevel gear 4, the first driven bevel gear 7 and the first driving bevel gear 4 being adapted to each other, and a second driven bevel gear 8 fixedly connected to the upper end of the second rotating sleeve 6, the surface of the second driven bevel gear 8 meshing with the first driving bevel gear 4. The second driven bevel gear 8 is meshed with the first driving bevel gear 4. The lower part of the first rotating shaft 5 is fixedly connected to the first blade 9, and the lower part of the second rotating sleeve 6 is fixedly connected to the second blade 10. After the waste from the animal experiment is put into the outer shell 1, the motor 3 is started. The motor 3 drives the first driving bevel gear 4 to rotate, which in turn drives the first driven bevel gear 7 and the second driven bevel gear 8 to rotate in opposite directions. The first rotating shaft 5 and the second rotating sleeve 6 drive the first blade 9 and the second blade 10 to rotate, so that the waste is crushed when it comes into contact with the first blade 9 and the second blade 10. This allows the waste to be crushed immediately while it is being temporarily stored, reducing the volume of the waste and reducing the number of processing steps. Moreover, the use of double blades for bidirectional crushing can form cross shearing and bidirectional tearing forces, making it easier to cut bones and tendon meat, resulting in higher crushing efficiency.

[0026] like Figure 1 - Figure 2 As shown: The upper end of the outer shell 1 is rotatably connected to the opening and closing door 11, and the lower end of the opening and closing door 11 is fixedly connected to the spring 12. The fixed end of the spring 12 is fixedly connected to the outer shell 1. By setting it so that when the waste is put on the opening and closing door 11, it will press the opening and closing door 11 to rotate and slide into the outer shell 1, and close under the push of the spring 12, thus preventing the odor from escaping during waste disposal.

[0027] like Figure 1 As shown: The lower end of the first rotating shaft 5 is fixedly connected to the transmission shaft 13, and the end of the transmission shaft 13 is fixedly connected to the second driving bevel gear 14. When the first rotating shaft 5 rotates, it drives the transmission shaft 13 to rotate, thereby driving the second driving bevel gear 14 to rotate inside the outer casing 1.

[0028] like Figure 1As shown: The inner circumference of the outer shell 1 is connected to the third driven bevel gear 15. The inner circumference of the outer shell 1 is equal to the outer circumference of the third driven bevel gear 15. The surface of the second driving bevel gear 14 meshes with the third driven bevel gear 15. The second driving bevel gear 14 and the third driven bevel gear 15 are adapted to each other. When the second driving bevel gear 14 rotates, it drives the third driven bevel gear 15 to rotate inside the outer shell 1.

[0029] like Figure 1 As shown: A conveying pipe 16 is fixedly connected to the side end of the outer shell 1. A conveying roller 17 is rotatably connected inside the conveying pipe 16. The inner circumference of the conveying pipe 16 is equal to the outer circumference of the conveying roller 17. The side end of the conveying roller 17 is fixedly connected to the third driven bevel gear 15. When the third driven bevel gear 15 rotates, it drives the conveying roller 17 to rotate as well, so that the crushed waste can be transported to the storage location by the rotating conveying roller 17.

[0030] like Figure 1 - Figure 4 As shown: A separation screen cylinder 18 is fixedly connected inside the material conveying pipe 16. Several holes are opened on the surface of the separation screen cylinder 18. When the crushed waste is conveyed by the material conveying roller 17, it is squeezed through the separation screen cylinder 18 to achieve the effect of solid-liquid separation. The solid continues to be conveyed while the liquid flows out from the holes of the separation screen cylinder 18.

[0031] like Figure 1 - Figure 4 As shown: An inclined block 19 is fixedly connected inside the material conveying pipe 16. The surface angle of the inclined block 19 is inclined. An outlet pipe 20 is fixedly connected inside the material conveying pipe 16. The material conveying pipe 16 is fixedly positioned relative to the bottom end of the inclined block 19, so that the separated liquid can flow down along the inclined block 19 and be discharged through the outlet pipe 20, thereby avoiding liquid accumulation inside.

[0032] Working principle:

[0033] like Figure 1 - Figure 4 As shown:

[0034] In use: After the waste from animal experiments is put into the outer casing 1, the motor 3 is started. The motor 3 drives the first active bevel gear 4 to rotate, which in turn drives the first driven bevel gear 7 and the second driven bevel gear 8 to rotate in opposite directions. The first rotating shaft 5 and the second rotating sleeve 6 drive the first blade 9 and the second blade 10 to rotate, so that the waste is crushed when it comes into contact with the first blade 9 and the second blade 10. This allows the waste to be crushed immediately while it is being temporarily stored, reducing the volume of the waste and reducing the number of processing steps. Moreover, the use of double blades for bidirectional crushing can form cross shearing and bidirectional tearing forces, making it easier to cut bones and tendon meat, resulting in higher crushing efficiency.

[0035] The third driven bevel gear 15 rotates while driving the conveyor roller 17 to rotate as well, so that the crushed waste can be transported to the storage location by the rotating conveyor roller 17. While the crushed waste is being transported by the conveyor roller 17, it is squeezed and passes through the separation screen 18 to achieve a better solid-liquid separation effect. The solid continues to be transported while the liquid flows out from the holes of the separation screen 18. The conveyor pipe 16 is fixed at the bottom of the inclined block 19, so that the separated liquid can flow down the inclined block 19 and be discharged through the liquid outlet pipe 20, thereby avoiding the accumulation of liquid inside.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
