Description

Technical Field

[0001] The utility model relates to the field of centrifuges, in particular to a material discharge structure of a flat centrifuge. Background Art

[0002] The plate centrifuge is a widely used type of centrifuge with the characteristics of low noise, low energy consumption, high efficiency, compact structure and simple operation. It uses a high-speed rotating disc or plate to separate solid particles or liquids from the mixture by centrifugal force, achieving a fast and efficient separation process. In order to effectively separate the solid and liquid phases of the mixture and quickly discharge the material, the plate centrifuge often needs to install a filter bag in the drum and fix it to the drum. The separation effect can be achieved by adding the mixture to the filter bag and then running it.

[0003] However, in the prior art, the connection between the filter bag and the drum is open. Although the mixture adheres to the side wall due to the centrifugal force during operation, it is inevitable that part of the mixture will leak out from the open mouth and enter the interior of the centrifuge shell, causing cleaning difficulties and blocking the liquid phase flow outlet.

[0004] In view of this, we need to provide a plate centrifuge unloading structure to improve the above problems. Utility Model Content

[0027] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figures 1 to 6As shown, the utility model proposes a flat centrifuge unloading structure, which mainly includes a drum 1, a filter bag 4, a locking assembly 6, a limiting structure 14 and a collecting basin 15, wherein the drum 1 is used to be placed inside the centrifuge and receive the rotation drive of the centrifuge. Since the centrifuge belongs to the prior art, its technical principle will not be repeated here. A protrusion 2 is provided inside the drum 1, and a thread 3 is provided on the top of the outer periphery of the drum 1; a filter bag 4 is provided inside the drum 1. Since the filter bag 4 is made of a soft material, when it is placed inside the drum 1, it can fit well with the internal structure of the drum 1. Therefore, the middle part of its bottom end will also protrude along with the protrusion 2. When the mixture is added to the filter bag 4, the mixture will first fall on the protrusion 2, and then fall on the bottom of the drum 1 by gravity, which is more conducive to it fitting on the side wall of the drum 1 during centrifugation. Subsequently, a lifting ring 5 is provided on the inner bottom of the filter bag 4; when the filter bag 4 is placed in the drum 1, the lifting ring 5 falls just above the protrusion 2. After centrifugation, the entire filter bag 4 can be lifted or reversed by the lifting ring 5 to complete the material unloading process.

[0030] The lock assembly 6 is arranged above the filter bag 4. Through the arrangement of the lock assembly 6, the filter bag 4 can be directly fixed above the drum 1, and the structure can be controlled to control the opening and closing of the filter bag 4. When it is necessary to load materials, it can be controlled to open, and when it is necessary to centrifuge, it can be controlled to close, thereby avoiding the risk of the materials in the filter bag 4 splashing out from the open mouth due to centrifugation. After the centrifugation is completed, the user can lift it together with the filter bag 4 for easy unloading.

[0031] Specifically, the lock assembly 6 includes a lower ring 7, the top of which is fixedly connected to a plurality of uniformly distributed limiting posts 8, the bottom of which is provided with a threaded groove 18, and the drum 1 is threadedly connected to the inside of the threaded groove 18 through a thread 3. The top of the lower ring 7 is connected to an upper ring 9, which is provided with a plurality of rotation grooves 10 for use with the limiting posts 8. An inner ring 11 is arranged above the inside of the upper ring 9, and the bottom of the inner ring 11 is rotatably connected to a plurality of opening and closing plates 12 uniformly distributed around it, the shapes of the opening and closing plates 12 are mutually matched, and the side of the opening and closing plate 12 away from the inner ring 11 is rotatably connected to a circular arc-shaped rotating plate 13, and the rotating plate 13 is rotatably connected to the upper ring 9, and the filter bag 4 is detachably connected to the inside of the inner ring 11; the upper ring 9 is fixedly connected to a plurality of uniformly distributed hooks 34. Furthermore, a plurality of evenly distributed plug-in shafts 20 are plugged into the inner ring 11, the plug-in shaft 20 is interconnected with the opening and closing plate 12, the plug-in shaft 1 21 is plugged into the side of the opening and closing plate 12 away from the plug-in shaft 3 20, the plug-in shaft 1 21 is interconnected with the rotating plate 13, the plug-in shaft 22 is plugged into the side of the rotating plate 13 away from the plug-in shaft 21, and the plug-in shaft 22 is plugged into the upper ring 9.

[0032] Therefore, by rotating the upper ring 9 relative to the lower ring 7, each insertion shaft 21 can be driven to perform circular motion, and the rotating plate 13 connected thereto can be driven to move, thereby pushing the opening and closing plate 12 to rotate around the insertion shaft 3 20, thereby achieving the function of adjusting the opening and closing degree.

[0033] The opening and closing of the lock assembly 6 needs to be completed by the limiting structure 14, and the limiting structure 14 includes a top block 23 fixedly connected to one side of the upper ring 9, and a through slot 24 is opened on the top block 23. A plurality of bottom blocks 25 used in conjunction with the top block 23 are fixedly connected to the lower ring 7, and a groove 26 is opened on the bottom block 25. The top of the top block 23 is fixedly connected to a fixed block 27, and a through hole 28 is opened in the fixed block 27. A pulling portion 29 is provided at the top of the fixed block 27, and a plug 30 is fixedly connected to the bottom end of the pulling portion 29. The plug 30 passes through the through hole 28, the through slot 24 and the groove 26 in sequence. A spring 31 is sleeved on the periphery of the plug 30, and the top and bottom ends of the spring 31 are fixedly connected to a limiting plate 32 and a limiting block 33 respectively. The limiting plate 32 is fixedly connected in the through hole 28 and is movably connected to the plug 30, and the limiting block 33 is fixedly connected to the plug 30.

[0034] Therefore, when it is necessary to rotate the upper ring 9, the user needs to pull the pulling part 29 first to drive the pin 30 away from the groove 26. At this time, the limit block 33 approaches the limit plate 32 and squeezes the spring 31. When the pin 30 is completely out of the groove 26, the upper ring 9 and the lower ring 7 are released from the limit. The user can move the upper ring 9 to the target position and align the pin 30 with the groove 26 at the target position. Then, let go, the pin 30 is inserted, and the fixation is finally completed.

[0035] After the centrifugal device completes the centrifugation, the liquid phase and the solid phase of the mixture are separated, and the solid phase remains inside the filter bag 4. At this time, the user can rotate the lower ring 7 out of the drum 1, and lift it out with the filter bag 4 through the hook 34 to complete the unloading, or put the collection basin 15 above the upper ring 9. The collection basin 15 has a discharge port 16 in the middle of the bottom end. The bottom end of the inner wall of the collection basin 15 is fixedly connected with a hollow discharge column 17, and the bottom end of the discharge column 17 is connected to the discharge port 16. At the same time, the bottom end of the collection basin 15 is fixedly connected with a convex ring 19, and the size of the convex ring 19 is consistent with that of the inner ring 11. Therefore, when unloading, the user can put his hand or a lifting tool deep into the hollow unloading column 17, enter the interior of the filter bag 4 along the column channel, and then hang it above the ring 5 to lift the ring 5. At this time, the interior of the filter bag 4 will turn over accordingly, and the solid phase inside will be shaken out, so that it will fall into the collection basin 15, completing the collection, and then the collection basin 15 can be transported away.

[0036] It should be specially noted here that the components described and identified in the text and drawings of the utility model are the key components constituting the utility model, and the remaining non-key components or obvious prior art components, such as screws, nuts and other connectors, and technical features similar to the prior art are not shown. However, this does not mean that the above-mentioned components do not exist in the utility model, nor can it be interpreted as a practical limitation on the utility model.

[0037] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
