Abstract
Description
Technical Field
[0001] This utility model relates to the field of centrifuge unloading technology, and in particular to a centrifuge auxiliary unloading device. Background Technology
[0002] When the bottom discharge centrifuge is working, it separates the solid-liquid mixture through the rotating drum. After the separation is completed, the material on the inner wall of the rotating drum is scraped off by the scraping device and falls from the bottom of the rotating drum into the discharge hopper and is discharged through the discharge hopper. This type of centrifuge is very convenient for unloading, so it is widely used in the food and pharmaceutical industries. Although bottom-discharge centrifuges are convenient to use, material often accumulates in the discharge hopper. Because the discharge hopper is installed below the drum, a considerable distance from the top of the centrifuge, and the hopper itself is quite tall, cleaning from either the top or bottom is very inconvenient. For materials that cannot be exposed to air, they can only be tapped from the outside, which is time-consuming. Therefore, this invention proposes a centrifuge-assisted discharge device to solve the above problems. Utility Model Content
[0003] To address the aforementioned problems, this utility model proposes a centrifugal auxiliary feeding device to solve the problem in the prior art where material often accumulates in the unloading hopper, which is located below the drum and far from the top of the centrifuge, and is also tall, making cleaning from top to bottom extremely inconvenient.
[0004] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a centrifugal assisted feeding device, including a discharge hopper, an upper fixed part and a lower fixed part. The top of the discharge hopper is fixedly connected to the upper fixed part, and a central shaft is rotatably connected inside the upper fixed part. The top of the upper fixed part is provided with a rotating mechanism that matches the central shaft. The bottom end of the central shaft is fixedly connected to a pull rod, and a scraper is hinged to one end of the pull rod. The top end of the central shaft is provided with a telescopic mechanism, which is hinged to the top end of the scraper.
[0005] Further improvements are made in the following aspects: The telescopic mechanism includes an upper pull rod, a threaded rod, a slider, a main frame tube, and a rotating torque. The upper pull rod is fixedly connected to the top of the central shaft. The upper pull rod has a threaded rod inside and a main frame tube inside. A slider is fixedly connected to one end of the threaded rod. The threaded rod is slidably connected to the main frame tube through the slider. A rotating torque is rotatably connected to one end of the upper pull rod. The outer wall of the threaded rod is threadedly connected to the inner wall of the rotating torque. A strip groove is provided at the hinge point between the scraper and the threaded rod.
[0006] A further improvement is that the rotating mechanism includes a bevel gear and a rotary motor. The rotary motor is fixedly installed on one side of the top of the upper fixing member. The top of the central shaft and the output end of the rotary motor are both fixedly connected to bevel gears, and the outer sides of the two bevel gears mesh with each other.
[0007] A further improvement is that multiple anti-slip strips are fixedly connected to the outer side of the rotating knob, the distance between adjacent anti-slip strips is equal, and the structure of the anti-slip strips is set as a rectangular structure.
[0008] A further improvement is that a sealing shell is provided on the outside of the rotary motor, and a sealing bearing is installed on one side of the sealing shell. The output end of the rotary motor is rotatably connected to the sealing shell through the sealing bearing.
[0009] A further improvement is that the bottom of the unloading hopper is fixedly connected to a discharge port via a lower fixing component, and a solenoid valve is installed on the discharge port.
[0010] Further improvements include: opening the auxiliary feeding device before discharge, or opening the auxiliary feeding device after the discharge bridge is in place.
[0011] The beneficial effects of this utility model are as follows: the rotary motor can drive the bevel gear at its output end to rotate, and this bevel gear meshes with the bevel gear at the top of the central shaft. The output end of the rotary motor can drive the central shaft to rotate, and the central shaft drives the scraper to rotate inside the discharge hopper. The scraper is in contact with the inner wall of the discharge hopper to scrape the material inside the discharge hopper and flow downwards, assisting the material to be discharged. Twisting the rotary knob forward and backward can drive the threaded rod to move linearly back and forth, so as to drive the scraper to rotate around one end of the pull rod. Controlling whether one side of the scraper is in contact with the inner wall of the discharge hopper makes it convenient to clean the scraper. Attached Figure Description

Detailed Implementation
[0014] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.
[0015] according to Figure 1 , 2As shown in Figure 3, this embodiment proposes a centrifugal assisted feeding device, including a discharge hopper 1, an upper fixing member 2, and a lower fixing member 3. The top of the discharge hopper 1 is fixedly connected to the upper fixing member 2, and a central shaft 4 is rotatably connected inside the upper fixing member 2. The top of the upper fixing member 2 is provided with a rotating mechanism that matches the central shaft 4. The bottom end of the central shaft 4 is fixedly connected to a pull rod 6, and a scraper 7 is hinged to one end of the pull rod 6. The top end of the central shaft 4 is provided with a telescopic mechanism, which is hinged to the top end of the scraper 7. The material inside the centrifuge falls into the interior of the discharge hopper 1. The rotating mechanism drives the scraper 7 to rotate inside the discharge hopper 1 through the central shaft 4. The scraper 7 is in contact with the inner wall of the discharge hopper 1 to scrape the material inside the discharge hopper 1 and make it flow downward, thus assisting in the feeding of the material. The telescopic mechanism drives the scraper 7 to move around the pull rod 6 to control whether it is in contact with the inner wall of the discharge hopper 1, which facilitates the cleaning of the scraper 7.
[0016] The rotating mechanism includes a bevel gear 12 and a rotary motor 13. The rotary motor 13 is fixedly installed on one side of the top of the upper fixing member 2. The top of the central shaft 4 and the output end of the rotary motor 13 are both fixedly connected to the bevel gear 12. The outer sides of the two bevel gears 12 mesh with each other. The rotary motor 13 can drive the bevel gear 12 at its output end to rotate. This bevel gear 12 meshes with the bevel gear 12 at the top of the central shaft 4. The output end of the rotary motor 13 can drive the central shaft 4 to rotate.
[0017] The telescopic mechanism includes an upper pull rod 5, a threaded rod 8, a slider 9, a main frame tube 10, and a rotating torque 11. The upper pull rod 5 is fixedly connected to the top of the central shaft 4. The threaded rod 8 is located inside the upper pull rod 5, and the main frame tube 10 is located inside the upper pull rod 5. The slider 9 is fixedly connected to one end of the threaded rod 8, and the threaded rod 8 is slidably connected to the main frame tube 10 through the slider 9. The rotating torque 11 is rotatably connected to one end of the upper pull rod 5. The outer wall of the threaded rod 8 is threadedly connected to the inner wall of the rotating torque 11. A strip groove is provided at the hinge point between the scraper 7 and the threaded rod 8. The slider 9 and the main frame tube 10 restrict the movement trajectory of the threaded rod 8. The rotating torque 11 is threadedly engaged with the threaded rod 8. Twisting the rotating torque 11 forward and backward can drive the threaded rod 8 to move linearly back and forth, thereby driving the scraper 7 to rotate around one end of the lower pull rod 6. This controls whether one side of the scraper 7 is in contact with the inner wall of the discharge hopper 1, which facilitates cleaning of the scraper 7. Furthermore, the hinge point between the threaded rod 8 and the scraper 7 can slide inside the strip groove to avoid interference.
[0018] Multiple anti-slip strips are fixedly connected to the outer side of the rotating twist 11. The distance between adjacent anti-slip strips is equal. The anti-slip strips are designed with a rectangular structure to increase the friction on the outer surface of the rotating twist 11 and reduce the slippage phenomenon when twisting the rotating twist 11.
[0019] The rotary motor 13 is provided with a sealing shell on the outside, and a sealing bearing is installed on one side of the sealing shell. The output end of the rotary motor 13 is rotatably connected to the sealing shell through the sealing bearing. The sealing shell and the sealing bearing can enclose the rotary motor 13 without affecting the rotation of the output end of the rotary motor 13, thus protecting the rotary motor 13.
[0020] The bottom of the unloading hopper 1 is fixedly connected to the discharge port 14 by the lower fixing member 3. A solenoid valve 15 is installed on the discharge port 14. The upper fixing member 2 discharges material downward through the discharge port 14. The solenoid valve 15 can control the opening or closing of the discharge port 14 so that the material is discharged as needed.
[0021] The auxiliary feeding device can be opened before discharge or after the discharge bridge is erected.
[0022] In this centrifugal assisted feeding device, the rotary motor 13 can drive the bevel gear 12 at its output end to rotate. This bevel gear 12 meshes with the top bevel gear 12 of the central shaft 4. The output end of the rotary motor 13 can drive the central shaft 4 to rotate, which in turn drives the scraper 7 to rotate inside the discharge hopper 1. The scraper 7 is in contact with the inner wall of the discharge hopper 1 to scrape the material inside the discharge hopper 1 and make it flow downward, thus assisting in the feeding of the material. Twisting the rotary knob 11 in both directions can drive the threaded rod 8 to move linearly back and forth, thereby driving the scraper 7 to rotate around one end of the pull rod 6. Controlling whether one side of the scraper 7 is in contact with the inner wall of the discharge hopper 1 makes it easier to clean the scraper 7.
