Description

Technical Field

[0001] This utility model relates to the field of animal fat processing technology, specifically to an animal fat separation and recovery device. Background Technology

[0002] Animal fats, if directly discharged or improperly treated, can clog municipal pipe networks and pollute water bodies and soil. For example, mixing fats with sewage and discharging them into sewers can cause pipe corrosion, and the organic matter in fats decomposes under anaerobic conditions to produce greenhouse gases such as methane, exacerbating climate change. Separation and recycling technologies use physical, chemical, or biological methods to efficiently separate fats, significantly reducing environmental impact and ensuring water quality meets discharge standards.

[0003] Currently, most animal fat solid-liquid separation and recovery devices on the market use disc separators. The disc separator has several conical discs arranged vertically in the drum. The conical discs can rotate at high speed driven by a motor. During the rotation, the heavier solid waste is thrown to the outer edge of the discs in the drum under the action of centrifugal force, while the lighter fat is separated and gathers in the middle of the drum. When the solid waste accumulates to a certain amount, the edge of the drum can be opened for a very short moment, and the solid waste is thrown out, thus completing the solid-liquid separation of animal fat. During its production operations, the applicant observed that in order for the conical discs of the disc separator to generate sufficient centrifugal force to separate solid waste from animal fats, the conical discs need to reach 6,000-10,000 revolutions per minute driven by the motor. The high-speed rotation of the conical discs, gearbox, and motor generates severe vibrations. Because this type of separator is usually directly fixed to the ground, the level of the drum cannot be adjusted, resulting in even greater vibrations during high-speed rotation. These vibrations are directly transmitted to the building structure of the factory, causing cracks in the factory walls and damage to the building structure. Furthermore, the vibrations are transmitted to other production workshops within the factory, severely affecting the normal work of workers in those workshops. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an animal fat separation and recovery device.

[0005] The technical solution of this utility model is as follows:

[0006] An animal fat separation and recovery device includes a drive motor, a gearbox, and a rotating drum. The rotating drum is driven by the drive motor via the gearbox. The device also includes a shock-absorbing base, which comprises a lower chassis. The upper surface of the lower chassis has several vertically connected lower support legs, and the lower surface of the gearbox has several vertically connected upper support legs. The number of upper support legs is the same as the number of lower support legs. A buffer unit is provided between the upper and lower support legs, and the buffer unit includes a buffer spring and a limiting pin. A limiting hole is provided in the middle of the upper end of each lower support leg. The upper end of the limiting pin can pass through the limiting hole and be threadedly connected to the lower end of the upper support leg, thereby limiting the relative position of the upper and lower support legs. The total length of the upper and lower support legs can also be adjusted by rotating the limiting pin. The buffer spring is arranged around the corresponding limiting pin, with its upper end in contact with the lower surface of the upper support leg and its lower end in contact with the upper surface of the lower support leg. The elasticity of the buffer spring can buffer the vibration generated by the operation of the drive motor, gearbox and drum, preventing the vibration from being directly transmitted to the building structure of the factory through the ground, and also preventing the vibration from being transmitted to other production workshops in the factory.

[0007] To prevent debris from entering the buffer spring or to prevent operators from accidentally touching the buffer spring, the buffer unit also includes a shielding cylinder. The shielding cylinder is arranged around the buffer spring, with its upper end in contact with the outer side of the lower end of the upper support leg and its lower end in contact with the outer side of the lower end of the upper support leg.

[0008] During the process of adjusting the overall length of the upper and lower support legs, the overall length of the buffer spring will change. In order for the shielding cylinder to adapt to the change in the length of the buffer spring, the shielding cylinder is made of rubber material, and the shape of the shielding cylinder wall includes a wavy shape.

[0009] Preferably, to prevent the buffer spring from pressing against the inner wall of the shielding cylinder during compression, the inner diameter of the shielding cylinder is 10-15 mm larger than the outer diameter of the buffer spring.

[0010] To prevent the buffer spring from becoming misaligned and falling off after compression, the upper and lower supports are provided with protruding limiting platforms at the contact points with the buffer spring. The diameter of the limiting platforms matches the inner diameter of the buffer spring.

[0011] Furthermore, to ensure that the upper and lower ends of the buffer spring are sufficiently stable after being installed on the corresponding limiting platform, the height of the limiting platform is not less than 5cm.

[0012] To reduce the noise generated by the friction of the buffer spring, noise-reducing washers are provided at both the upper and lower ends of the buffer spring. The noise-reducing washers are made of rubber material and have a thickness of not less than 1 cm.

[0013] Furthermore, to ensure that the buffer spring can provide sufficient cushioning capacity, the wire diameter of the buffer spring is 10-15mm.

[0014] To facilitate the rotation and adjustment of the limiting pin and the adjustment of the total length of the upper and lower support legs, an adjustment head is provided at the lower end of the limiting pin. The adjustment head is hexagonal in shape, and an adjustment port is provided on the side of the lower support leg at the position of the adjustment head.

[0015] To facilitate operators in determining whether the drive motor, gearbox, and drum are in a perfectly horizontal position, bubble level instruments are installed on the front, rear, left, and right surfaces of the gearbox.

[0016] The beneficial effects of this utility model are as follows:

[0017] This utility model discloses an animal fat separation and recovery device. A buffer unit is provided between the upper and lower support legs of the animal fat separation and recovery device. The buffer unit is equipped with a buffer spring that can buffer the severe vibrations generated by the high-speed rotating conical disc, gearbox and motor. The buffer unit is also equipped with a limiting pin connecting the upper and lower support legs. The total length of the upper and lower support legs is adjusted by the limiting pin so that the conical disc can rotate horizontally and avoid its biased rotation from generating greater vibrations. The buffer unit can prevent the vibration from being transmitted through the building structure to the entire factory, protecting the structural strength of the factory and avoiding affecting the normal work of workers in other workshops of the factory.

[0024] See Figures 1-3 An animal fat separation and recovery device includes a drive motor 1, a gearbox 2, and a rotating drum 3. The rotating drum 3 is driven by the drive motor 1 through the gearbox 2. The lower end of the drive motor 1 has an extended output shaft, which is driven by the gearbox 2. The lower end of the rotating drum 3 has an extended rotating shaft. The gearbox 2 contains a transmission belt, one end of which is driven by the output shaft of the drive motor 1, and the other end of which is driven by the rotating shaft of the rotating drum 3. The drive motor 1 can be driven by the transmission belt in the gearbox 2. The transmission belt drives the conical disc in the drum 3 to rotate. The animal fat separation and recovery device also includes a shock-absorbing base 4, which includes a lower chassis 41. The upper surface of the lower chassis 41 is provided with several vertically connected lower support legs 42. The lower surface of the gearbox 2 is provided with several vertically connected upper support legs 43. The number of upper support legs 43 is the same as the number of lower support legs 42. A buffer unit 44 is provided between the upper support legs 43 and the lower support legs 42. The buffer unit 44 includes a buffer spring 441 and a limiting pin 4. 42. A limiting hole 421 is provided in the middle of the upper end of the lower support leg 42. The upper end of the limiting pin 442 can pass through the limiting hole 421 and be threadedly connected to the lower end of the upper support leg 43, thereby limiting the relative position of the upper support leg 43 and the lower support leg 42, preventing the shock-absorbing base 4 and the gearbox 2 from being misaligned. Moreover, by rotating the limiting pin 442, the total length of the upper support leg 43 and the lower support leg 42 can be adjusted so that the drive motor 1, the gearbox 2 and the drum 3 can be in a horizontal position, avoiding the conical disc in the drum 3. The offset leads to additional wear and vibration. The buffer spring 441 is arranged around the corresponding limit pin 442, with its upper end in contact with the lower end surface of the upper support leg 43 and its lower end in contact with the upper end surface of the lower support leg 42. The elasticity of the buffer spring 441 can buffer the vibration generated by the operation of the drive motor 1, gearbox 2 and drum 3, and prevent the vibration from being directly transmitted to the building structure of the factory through the ground, thus preventing damage to the building structure of the factory, and also preventing the vibration from being transmitted to other production workshops in the factory, affecting the workers in other production workshops.

[0025] To prevent foreign objects from entering the buffer spring 441, or to prevent the operator from accidentally touching the buffer spring 441, see [link to relevant documentation]. Figure 3The buffer unit 44 also includes a shielding cylinder 443, which is arranged around the buffer spring 441. The upper end of the shielding cylinder 443 is in contact with the outer side of the lower end of the upper support leg 43, and its lower end is in contact with the outer side of the lower end of the upper support leg 43. The shielding cylinder 443 can shield the buffer spring 441, protect the buffer spring 441, and prevent the operator from accidentally touching it and getting injured.

[0026] During the process of adjusting the overall length of the upper support leg 43 and the lower support leg 42, the overall length of the buffer spring 441 will change. In order for the shielding cylinder 443 to adapt to the length change of the buffer spring 441, the shielding cylinder 443 is made of rubber material, and the shape of the cylinder wall of the shielding cylinder 443 includes a wave shape, so that the shielding cylinder 443 can adapt to the expansion and contraction of the buffer spring 441.

[0027] Preferably, to prevent the buffer spring 441 from pressing against the inner wall of the shielding cylinder 443 during compression, the inner diameter of the shielding cylinder 443 is 10-15mm larger than the outer diameter of the buffer spring 441, thereby ensuring that the buffer spring 441 cannot press against the inner wall of the shielding cylinder 443 during compression, and preventing the shielding cylinder 443 from being damaged by compression and squeezing by the buffer spring 441.

[0028] To prevent the upper and lower ends of the buffer spring 441 from being offset relative to the upper support leg 43 and the lower support leg 42 after compression, which would cause the buffer spring 441 to misalign and fall off, the upper support leg 43 and the lower support leg 42 are respectively provided with protruding limiting platforms 45 at the positions where they contact the buffer spring 441. The diameter of the limiting platform 45 matches the inner diameter of the buffer spring 441, thereby ensuring that the upper and lower ends of the buffer spring 441 can be sleeved and connected on the corresponding limiting platforms 45, preventing the upper and lower ends of the buffer spring 441 from being offset and causing the upper support leg 43 and the lower support leg 42 to misalign.

[0029] Furthermore, in order to ensure that the upper and lower ends of the buffer spring 441 are sufficiently stable after being installed on the corresponding limiting platform 45, the height of the limiting platform 45 is not less than 5cm, thereby ensuring that the upper and lower ends of the buffer spring 441 can be stably installed on the corresponding limiting platform 45 and preventing the upper and lower ends of the buffer spring 441 from detaching from the corresponding limiting platform 45.

[0030] To reduce the noise generated by friction from the buffer spring 441, see [link to relevant documentation]. Figure 3 The upper and lower ends of the buffer spring 441 are provided with noise-reducing washers 444. The noise-reducing washers 444 are made of rubber material and the thickness of the noise-reducing washers 444 is not less than 1cm, thereby ensuring that the noise-reducing washers 444 can reduce the vibration generated by the friction between the upper and lower ends of the buffer spring 441 and the upper support leg 43 and the lower support leg 42.

[0031] Furthermore, in order to ensure that the buffer spring 441 can provide sufficient buffering capacity, the wire diameter of the buffer spring 441 is 10-15mm. If the buffer spring 441 is too thick or too thin, it will affect the buffering capacity it provides. The wire diameter setting of the buffer spring 441 mentioned above can ensure that its buffering capacity is sufficient to offset the vibration generated by the operation of the drive motor 1, gearbox 2 and drum 3.

[0032] For easy rotation and adjustment of the limit pin 442, see [link / reference] Figure 3 The total length of the upper support leg 43 and the lower support leg 42 is adjusted. An adjusting head 445 is provided at the lower end of the limiting pin 442. The adjusting head 445 is hexagonal in shape. An adjusting port 422 is provided on the side of the lower support leg 42 at the position of the adjusting head 445. The setting of the adjusting port 422 allows the operator to easily insert a wrench to rotate the adjusting head 445 and adjust the limiting pin 442.

[0033] To help operators determine whether the drive motor 1, gearbox 2, and drum 3 are in a perfectly horizontal position, please refer to... Figure 1 and Figure 2 Bubble level 5 is provided on the front, rear, left and right surfaces of the gearbox 2. The operator can directly observe the corresponding bubble level 5 to judge the level of the drive motor 1, gearbox 2 and drum 3, and then adjust the corresponding upper support leg 43 and lower support leg 42.
