Description

Technical Field

[0001] The utility model relates to the technical field of plate centrifuges, in particular to a discharging device for a plate centrifuge. Background Art

[0002] The plate centrifuge is used to separate some granular products, throwing out the small particles in the raw materials and leaving the large particles. The plate centrifuge is easy to use and has good effects, so it has been widely used in laboratories.

[0003] At present, the use method of the flat plate centrifuge is to first place the material to be centrifuged in the centrifuge cup and keep the material balance in the centrifuge cup, then place the centrifuge cup on the rotor, and install the rotor on the main shaft of the centrifuge. Next, set the speed and running time of the centrifuge, and start the centrifuge. After the centrifuge starts to rotate, the centrifugal force will separate the material in the centrifuge cup, the heavier material will be deposited at the bottom of the centrifuge cup, and the lighter material will float to the top of the centrifuge cup. Finally, stop the operation of the centrifuge, take out the centrifuge cup, and take out the separated material for subsequent processing.

[0004] Although the above method can take out the raw materials inside the centrifuge, this method of taking out is manual. After the separation of the raw materials is completed, the control device stops working, and then the centrifugal cup is taken out to take out the raw materials remaining inside the centrifugal cup. This method of discharging is cumbersome and requires opening the positioning devices on the centrifugal cup one by one, which wastes time and reduces work efficiency. Therefore, we propose a flat centrifuge discharging device to solve the above problems. Utility Model Content

[0028] Example

[0029] Reference Figure 1-Figure 6 The utility model provides a technical solution: a flat centrifuge discharging device, comprising a bottom plate 1 and a discharging mechanism 3, the upper surface of the bottom plate 1 is fixedly connected to the cylinder 2, the discharging mechanism 3 comprises a rotating cylinder 31, a rotatable mounting table 311 is mounted on the upper surface of the bottom plate 1, the upper surface of the rotatable table 311 is mounted with the rotating cylinder 31, the outer surface of the rotating cylinder 31 is provided with a through hole 312, the discharging hole 32 is provided on the outer surface of the cylinder 2, and the closing plate 33 is slidably mounted inside the discharging hole 32.

[0030] In a preferred embodiment, a sliding hole 4 is provided at the inner top of the discharge hole 32, and the interior of the sliding hole 4 is slidably connected to a closing plate 33, and the bottom of the closing plate 33 is fixedly connected to a first magnet 6, and a groove 7 is provided at a position on the upper surface of the bottom plate 1 corresponding to the closing plate 33, and the inner bottom of the groove 7 is fixedly connected to a second magnet 8, and the magnetic poles of the first magnet 6 and the second magnet 8 are opposite. In order to prevent the thrown raw materials from being thrown out through the position of the discharge hole 32 during the separation operation of the raw materials, and the separated raw materials are easily mixed together again during the subsequent unloading, a closing plate 33 is slidably installed inside the sliding hole 4, and a first magnet 6 is fixedly installed at the bottom of the closing plate 33, and the first magnet 6 is attracted to the second magnet 8, so that the closing plate 33 can be stably installed on the bottom plate 1, thereby blocking the thrown raw materials and discharging them from the position of the discharge pipe 15.

[0031] In a preferred embodiment, the bottom of the base plate 1 is fixedly connected to the driving motor 9, the output end of the driving motor 9 is fixedly connected to the transmission rod 10, one end of the transmission rod 10 is fixedly connected to the truncated cone 311, an annular groove 11 is provided on the upper surface of the truncated cone 311, the inside of the annular groove 11 is clamped with an annular plate 12, the top of the annular plate 12 is fixedly connected to the connecting rod 13, one end of the connecting rod 13 is fixedly connected to the rotating cylinder 31, after the raw material separation is completed, the raw material inside the rotating cylinder 31 can be taken out, and the rotating cylinder 31 can be pulled upward to distance it from the truncated cone 311. As the truncated cone 31 continues to rotate, the raw material is thrown onto the base plate 1 and discharged from the position of the discharge hole 32, so that the raw materials can be collected separately to avoid mixing together.

[0032] In the process of processing raw materials, whether it is the raw materials that are thrown out or the raw materials after separation, they must be discharged and taken out. In order to quickly discharge the raw materials, the present device has a pushing mechanism 14 fixedly installed on the outer surface of the rotating cylinder 31. The pushing mechanism 14 includes a connecting plate 141, a pushing plate 142 and a scraper 143. The connecting plate 141 is fixedly installed on the outer surface of the rotating cylinder 31. The bottom of the connecting plate 141 is fixedly connected to the pushing plate 142. The bottom of the pushing plate 142 is fixedly connected to the scraper 143. A discharge hole is provided on the upper surface of the bottom plate 1. The inside of the discharge hole is fixedly connected to a discharge pipe 15. A control valve 5 is provided on the outer surface of the discharge pipe 15. In actual use, by installing the connecting plate 141 on the outer surface of the rotating cylinder 31, the bottom of the connecting plate 141 is fixedly connected to the pushing plate 142, and the bottom of the pushing plate 142 is fixedly connected to the scraper 143, it is not only convenient to discharge large-particle raw materials, but also to discharge small-particle raw materials. Through the cooperation of the scraper 143 and the pushing plate 142, all the separated raw materials can be discharged, which is convenient for use.

[0033] Specifically, the working process or working principle of a plate centrifuge discharge device is as follows: the current method of using a plate centrifuge is to first place the material to be centrifuged in a centrifuge cup and keep the material balance in the centrifuge cup, then place the centrifuge cup on the rotor, and install the rotor on the main shaft of the centrifuge, then set the speed and running time of the centrifuge, and start the centrifuge. After the centrifuge starts to rotate, the centrifugal force will separate the material in the centrifuge cup, the heavier material will be deposited at the bottom of the centrifuge cup, and the lighter material will float to the top of the centrifuge cup, and finally, stop the operation of the centrifuge, take out the centrifuge cup, and take out the separated material for subsequent processing.

[0034] Although the above method can take out the raw materials inside the centrifuge, this method of taking out is manual. After the separation of the raw materials is completed, the control device stops working, and then the centrifugal cup is taken out to take out the raw materials remaining inside the centrifugal cup. This method of discharging is cumbersome to operate, and the positioning devices on the centrifugal cup need to be opened one by one, which wastes time and reduces work efficiency. Therefore, this device is designed to solve this problem. By connecting an external power supply, adding raw materials into the interior of the rotating cylinder 31, and covering the external top cover to seal the rotating cylinder 31, the drive motor 9 can be turned on. The driving motor 9 drives the truncated table 311 to rotate, which can drive the rotating cylinder 31 to rotate, and the small particles of raw materials inside the rotating cylinder 31 are thrown out from the position of the through hole 312 and fall into the interior of the cylinder 2, and the large particles of raw materials will remain in the interior of the rotating cylinder 31, thereby realizing the separation of the raw materials.

[0035] When the rotating cylinder 31 is continuously rotating, the connecting plate 141 is driven to rotate, and the pushing plate 142 and the scraper 143 are driven to rotate, pushing the small-particle raw materials to move them to the position of the discharge pipe 15, and the small-particle raw materials are completely discharged through the inside of the discharge pipe 15. As the rotating cylinder 31 is continuously rotating, the separation operation of the raw materials is completed, and at the same time, the small-particle raw materials are continuously pushed by the pushing plate 142, so that they are all discharged.

[0036] Then the raw materials inside the rotating cylinder 31 can be unloaded. At this time, the top cover is removed, and then the rotating cylinder 31 is pulled upward to separate the bottom end of the rotating cylinder 31 from the truncated table 311, and the large particles are exposed. At this time, the truncated table 311 is continued to be controlled to rotate, and the large particles of raw materials falling on the truncated table 311 are thrown out and also fall on the upper surface of the bottom plate 1. At this time, the closing plate 33 is pushed to move and the discharge hole 32 is opened. Under the continuous rotation of the rotating cylinder 31, the push plate 142 and the scraper 143 can rotate, thereby pushing the large particles to move, so that the large particles of raw materials pass through the inside of the discharge hole 32, move out of the inside of the cylinder 2, and enter the inside of the outer ring, so as to collect the raw materials inside the rotating cylinder 31.

[0037] It should be noted that the drive motor 9 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
