[0002] An explosion-proof centrifuge is a centrifugal separation device specifically designed for handling flammable, explosive, toxic, or volatile hazardous materials. Through special design and safety measures, it prevents explosions or fires caused by sparks, static electricity, or high temperatures during operation.

[0003] Existing centrifuges with hanging bags cannot fill the centrifuge interior with material due to the restraint of the hanging bags. This causes the centrifuge's center of gravity to shift. When rotating at high speed, this may cause severe vibration, accelerate the wear of bearings and main shaft, and in severe cases, trigger the centrifuge's automatic shutdown protection or even cause mechanical structural deformation.

[0004] Meanwhile, the explosion-proof flatbed hanging bag centrifuge disclosed in application number CN 214262355 U belongs to the technical field of hanging bag centrifuges. It includes a base, on which an outer shell is provided. This utility model sets up an installation component, and sets a fixed seat at the lower end of the drum, and the fixed seat and the card seat are engaged and connected.

[0005] However, the following problems were found in the implementation of the relevant technology: When filling the bag with materials, the centrifuge needs to be filled to ensure normal operation. If the material is insufficient, it may damage the centrifuge. However, sometimes it is not possible to fill the bag with materials every time. Utility Model Content

[0026] 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.

[0027] like Figures 1 to 5 As shown, this utility model provides an explosion-proof flat-plate hanging bag centrifuge, including a cylinder 1. A fixing column 2 is fixedly installed inside the cylinder 1, and a fixing plate 3 is fixedly installed inside the fixing column 2. A power assembly 4 is installed on the outside of the fixing plate 3. The power assembly 4 includes a motor 401 fixedly installed at the bottom of the fixing plate 3.

[0028] A rotating disk 402 is fixedly installed on the outside of the main shaft of the motor 401. Multiple arc-shaped grooves 403 are opened on the top surface of the rotating disk 402. A movable shaft 404 is movably installed inside the arc-shaped grooves 403. A connecting shaft 405 is fixedly installed on the bottom surface of the movable shaft 404 and passes through the fixed column 2. A pressing plate 406 is fixedly installed on the outside of the connecting shaft 405. The motor 401 is installed inside the fixed column 2 through the fixed plate 3. The motor 401 drives the rotating disk 402. When the rotating disk 402 rotates, it drives the movable shaft 404 inside the arc-shaped grooves 403 to move. During the movement, the movable shaft 404 pushes the pressing plate 406 outward through the connecting shaft 405, so that the hanging bag can be tightly attached to the inner wall of the centrifuge. This solves the problem of dynamic imbalance caused by the gap between the hanging bag and the inside of the centrifuge, improves the safety of centrifugal force during use, protects its internal components, and also improves the efficiency of centrifugation, indirectly reducing economic losses.

[0029] Specifically, a plurality of fixed seats 5 are fixedly provided on the bottom surface of the rotating disk 402. A fixed shaft 6 is fixedly provided inside the fixed seat 5. A sliding seat 407 is slidably provided on the outside of the fixed shaft 6. The sliding seat 407 is fixedly connected to the connecting shaft 405. The sliding seat 407 limits the connecting shaft 405 by interacting with the fixed seat 5.

[0030] Furthermore, a long shaft 408 is fixedly installed at the end of the main shaft of the motor 401, and another rotating disk 402 is fixedly installed at the top of the long shaft 408. Multiple rotating disks 402 drive multiple extrusion plates 406, thereby extruding different positions of the hanging bag.

[0031] Furthermore, a flat plate support 11 is fixedly installed at the bottom of the cylinder 1, and multiple fixed base plates 12 are fixedly installed at the bottom of the flat plate support 11. The flat plate support 11 and the fixed base plates 12 can increase the stability of the centrifuge.

[0032] It is worth noting that the fixed base plate 12 has a threaded rod 13 internally connected to it. A handwheel 14 is fixedly installed on the top surface of the threaded rod 13, and a long plate 15 is rotatably connected to the bottom surface of the threaded rod 13. A movable wheel 16 is fixedly installed on the bottom surface of the long plate 15. Rotating the handwheel 14 drives the threaded rod 13. The threaded rod 13 is threadedly connected to the fixed base plate 12, thereby driving the long plate 15 and the movable wheel 16 to move. When the movable wheel 16 contacts the ground, it can push the device to the designated position, which increases the flexibility and mobility of the device, while also ensuring absolute safety when it is required to be stationary.

[0033] It is worth noting that a first liquid outlet pipe 8 is fixedly installed on the bottom surface of the cylinder 1, and the first liquid outlet pipe 8 passes through the flat plate support 11. A second liquid outlet pipe 9 is fixedly installed on the bottom surface of the cylinder 1, and the second liquid outlet pipe 9 passes through the flat plate support 11. The first liquid outlet pipe 8 and the second liquid outlet pipe 9 are used to discharge the separated liquid.

[0034] It is worth mentioning that a cover 7 is rotatably mounted on the top surface of the cylinder 1, and a filter screen 10 is fitted inside the cover 7, and the filter screen 10 is fixedly connected to the cylinder 1.

[0035] Among them, motor 401 is existing technology and will not be described in detail; at the same time, this utility model also includes a power supply, controller, and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0036] Working principle:

[0037] When using the explosion-proof flat-plate hanging bag centrifuge, first, turn the handwheel 14. The handwheel 14 drives the threaded rod 13, which is threadedly connected to the fixed base plate 12, thereby moving the long flat plate 15 and the moving wheels 16. When the moving wheels 16 contact the ground, the device can be pushed to the designated position. Then, it is retracted and supported by the flat plate support 11. Next, the hanging bag containing the items to be processed is placed inside the cylinder 1, and then the cover 7 is closed. The volume of the hanging bag cannot fill the space between the fixed column 2 and the filter screen 10. At this time, the motor 401 in the power assembly 4 is turned on. The motor 401 is installed inside the fixed column 2 through the fixed plate 3. The motor 401 drives the rotating disk 402. The motor 401 also drives the long shaft 408. Another rotating disk 402 is moved. When the rotating disk 402 rotates, it drives the movable shaft 404 inside the arc groove 403 to move. During the movement, the movable shaft 404 pushes the extrusion plate 406 outward through the connecting shaft 405, so that the hanging bag can be tightly attached to the filter screen 10 to avoid eccentricity. When the connecting shaft 405 moves, it cooperates with the fixed shaft 6 inside the fixed seat 5 through the sliding seat 407 at the bottom to limit the movement. The first liquid outlet pipe 8 and the second liquid outlet pipe 9 are both used to discharge the separated liquid. This utility model solves the problem of dynamic imbalance caused by the gap between the hanging bag and the centrifuge, improves the safety of centrifugal force during use, protects its internal components, and also improves the efficiency of centrifugation, indirectly reducing economic losses.
