[0034] Example 1

[0035] A centrifugal filtration device for liquid media, such as Figures 1-4 As shown, the system includes a tank body 1; the tank body 1 has a sealing ring 8, which divides the tank body 1 into upper and lower parts, and the sealing ring 8 is fixed by a flange ring; the tank body 1 includes a mounting frame 2, and the tank body 1 is detachably mounted on the mounting frame 2; a support ring 3 is located below the mounting frame 2, and the mounting frame 2 is equidistantly mounted on the support ring 3; several hydraulic support rods 4 are located below the support ring 3; the hydraulic support rods 4 support and fix the support ring 3; a motor 9 is installed on the top of the tank body 1, and a drum baffle 14 is connected to the drive shaft of the motor. A first centrifuge chamber 15 and a second centrifuge chamber 16 are detachably mounted on the drum baffle 14. The first centrifuge chamber 15 is embedded in the second centrifuge chamber 16, and a rotating ring 18 is installed at the bottom of the second centrifuge chamber 16 and the bottom of the first centrifuge chamber 15.

[0036] In this example: by setting a sealing ring 8, the tank 1 is divided into upper and lower parts. This allows for more effective inspection and cleaning of the tank's interior. Simultaneously, the mounting bracket 2 and support ring 3 suspend and support the tank 1 in mid-air. The support ring 3 is further secured by four sets of hydraulic support rods 4. This makes the device suitable for most foundations, and the elevated design further facilitates the maintenance and operation of the tank 1.

[0037] By setting up the motor 9, when the motor 9 drives the first centrifuge chamber 15 and the second centrifuge chamber 16, a strong centrifugal force will be generated inside the tank 1. At the same time, the first centrifuge chamber 15 is provided with sieve holes, and the second centrifuge chamber 16 is a rigid mesh structure with the inner diameter of the mesh holes being smaller than the inner diameter of the sieve holes; different objects can be separated and filtered out. Meanwhile, the drum baffle 14 can initially screen the raw materials and filter out larger particles in advance.

[0038] Specifically: a feed pipe 10 fixed by a flange ring is installed on the top of the tank body 1, and two sets of auxiliary feed pipes 11 are also provided on the top of the tank body 1; the auxiliary feed pipes 11 are equipped with manual valves; and a discharge pipe 12 fixed by a flange ring is installed on the lower side of the tank body 1.

[0039] In this example: by setting the feed pipe 10 and auxiliary pipe 11, different raw materials can be added at any time without stopping the machine; at the same time, the discharge pipe 12 is provided to facilitate the recovery of the liquid obtained by centrifugation.

[0040] Specifically: the bottom center of the tank body 1 is provided with a waste pipe 13, the top is provided with a funnel, the waste pipe 13 is provided with a hollow support 20 inside, the hollow support 20 is provided with an electric telescopic rod 21, the electric telescopic rod 21 is connected with a blocking rod 22, and two blocking blocks adapted to the rotating ring 18 are arranged on the blocking rod 22, so that the first centrifugal chamber 15 and the second centrifugal chamber 16 are closed.

[0041] In this example: the waste pipe 13 at the bottom of the tank body 1 can timely transfer the solid or liquid separated by centrifugation out of the device; the hollow support 20 and the electric telescopic rod 21 are connected with the blocking rod 22. When the device works, the electric telescopic rod 21 and the blocking rod 22 close the rotating ring 18 of the first centrifugal chamber 15 and the second centrifugal chamber 16 through the blocking block, so that the objects separated by centrifugation are left in the centrifugal chamber. When the work is completed, the electric telescopic rod 21 moves upward, the gap between the rotating ring 18 and the blocking block is enlarged, and the filtered material will be directly taken by the waste pipe 13 through the funnel and discharged, reducing the manual intervention.

[0042] Specifically: the left and right sides of the tank body 1 are each provided with an alarm 6, and the end of the alarm 6 away from the center is connected with a locking rod 7 for locking a sealing ring 8. If the locking rod 7 is not locked when the motor 9 is started, the alarm 6 will continuously alarm.

[0043] In this example: by setting the alarm 6, when the motor 9 is about to run, the alarm 6 automatically detects whether the locking rod 7 is closed. If not, the motor 9 will not start and the alarm 6 will continuously alarm, reducing the occurrence of accidents.

[0044] Specifically: the inner wall of the tank body 1 is provided with a flow guide groove 17.

[0045] In this example: by setting the flow guide groove 17 on the inner wall of the tank body, the flow of the liquid can be guided; at the same time, the inner wall of the device can also be cleaned to the maximum extent during self-cleaning of the equipment.

[0046] Specifically: the tank body 1 is provided with a handle 5 on the outside.

[0047] In this example: by setting the handle 5, the tank body 1 can be moved and disassembled conveniently, and workers can maintain it conveniently.

[0048] Specifically: the tank body 1 is provided with a thermometer 19 on the top.

[0049] In this example: by setting the thermometer 19, can real-time grasp the temperature in the tank body 1, facilitate the judgment of the worker, in time operation.

[0050] Working principle: before the device is powered on, first confirm whether the device tank body 1 is installed neatly, the axis is consistent, if not, adjust the hydraulic support rod 4, put the tank body 1 right. After confirming that there is no foreign matter in the tank body, the device can be started, and the raw materials are input by using the feeding pipe 10. If other raw materials are needed, the auxiliary pipe 11 can be used to add materials. After the motor 9 is started according to the situation, the added raw materials are initially intercepted by the rotary drum baffle 14 outside the centrifugal bin. Then the first centrifugal chamber 15 and the second centrifugal chamber 16 separate objects with different densities in turn. The liquid left finally will fall into the tank wall of the tank body, and then the liquid will be introduced to the discharge pipe 12 by the flow guide groove 17 so that the liquid flows out. The remaining residue will be left at the bottom of the second centrifugal chamber 16. At this time, the electric lifting rod 21 is started, the sealing rod 22 moves the sealing block from the rotary ring 18, so that the residue enters the waste pipe 13, which can be recycled.

[0051] For the part not fully disclosed in the utility model, the person skilled in the art can ensure the smooth implementation of the scheme of the utility model based on common sense, normal thinking logic and existing technology.

[0052] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
