Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to an adjustable front wall plate of a centrifuge. Background Technique

[0002] A centrifuge is a machine that uses centrifugal force to separate the components in a mixture of liquid and solid particles or liquid and liquid. Centrifuges are mainly used to separate solid particles from a suspension from the liquid, or to separate two immiscible liquids with different densities in an emulsion (for example, to separate cream from milk); it can also be used to remove the liquid from wet solids, such as wringing wet clothes in a washing machine; special ultra-high-speed tubular separators can also separate gas mixtures with different densities; taking advantage of the fact that solid particles with different densities or particle sizes settle at different speeds in a liquid, some sedimentation centrifuges can also classify solid particles according to density or particle size.

[0003] After retrieval, as disclosed in a Chinese patent document, an adjustable front wall plate of a centrifuge [Application No.: CN201821382578.8]. This adjustable front wall plate of a centrifuge includes a front wall plate body of the centrifuge. An inner cavity is opened inside the front wall plate body of the centrifuge. A through hole is opened on one side of the inner cavity, and first grooves are opened at both ends of one inner side wall of the inner cavity. A sliding block is arranged inside the first groove. First semi-circles and second semi-circles are respectively fixedly connected to the upper surfaces of the two sliding blocks. Uprights are arranged upward on the upper surfaces of the first semi-circle and the second semi-circle. A second groove is opened at the upper end of the upright. A rotating shaft is arranged inside the second groove. There are two groups of the rotating shafts, and the two groups of rotating shafts are respectively fixedly connected to the two inner side walls of the second groove. A cross bar is rotatably connected between the two groups of rotating shafts. One end of the cross bar penetrates out of the through hole, and buckles are installed at both ends inside the through hole.

[0004] When the front wall plate disclosed in this patent is in use, the inner diameter of the front wall plate can be adjusted, thereby improving the applicability of the front wall plate in use. However, during the adjustment process, it is necessary to manually remove the cross bars on both sides from the buckles, move them and then limit the cross bars through the buckles, which is relatively cumbersome and inconvenient. Moreover, the first semi-circle and the second semi-circle cannot move simultaneously, and the staff needs to operate in steps, which not only increases the labor intensity of the staff, but also reduces the adjustment efficiency of the front wall plate.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4As shown in the figure, an adjustable front wall plate of a centrifuge includes the front wall plate body 1 of the centrifuge. An installation groove 2 is opened inside the front wall plate body 1 of the centrifuge. Both sides of the inner wall of the installation groove 2 are slidably connected with installation shells 3. The installation shells 3 are designed in an arc shape. One side of one installation shell 3 is clamped with the other installation shell 3. Under this action, the two installation shells 3 can be more stable after connection, effectively improving the service strength of the two installation shells 3 after connection. A sleeve 4 is fixedly connected to one side of the installation shell 3. A rotating rod 5 is rotatably connected to one side of the inner cavity of the installation groove 2. A first bevel gear 6 is fixedly connected above the surface of the rotating rod 5. A second bevel gear 7 is engaged with both sides of the first bevel gear 6. The first bevel gear 6 and the second bevel gear 7 are of the same size and are used in cooperation with each other. A threaded rod 8 is fixedly connected to one side of the second bevel gear 7. The surface of the threaded rod 8 is threadedly connected with the inner wall of the sleeve 4. Under this action, the rotating rod 5 can be rotated to drive the second bevel gear 7 to rotate through the first bevel gear 6. Under the action of the thread on the surface of the threaded rod 8, the two installation shells 3 can be moved so that they can move towards each other or in the opposite direction at the same time. This is not only relatively convenient but also can improve the adjustment efficiency of the wall plate. A support plate 10 is rotatably connected to one side of the surface of the threaded rod 8. One side of the support plate 10 is fixedly connected with the inner wall of the installation groove 2. Under this action, one end of the threaded rod 8 can be supported so that it can be more stable when rotating. The surface of the sleeve 4 is slidably connected with the inner wall of the installation groove 2. Under this action, the sleeve 4 can be limited so that it will not rotate in place under the influence of the thread on the surface of the threaded rod 8 during movement, effectively improving the stability of the installation shell 3 during movement. A bearing seat 9 is fixedly connected to one end of the threaded rod 8 away from the second bevel gear 7. One side of the bearing seat 9 is fixedly connected with the inner wall of the installation groove 2. Under this action, the threaded rod 8 can be supported so that it can be more stable when rotating, avoiding the influence of the unstable rotation of the threaded rod 8 on the threaded connection with the sleeve 4. One end of the rotating rod 5 penetrates to the outside of the front wall plate body 1 of the centrifuge and is rotatably connected with the inner wall at its penetration point. A rotating block 13 is fixedly connected to one end of the rotating rod 5. The rotating block 13 is designed as a regular hexahedron. The surface of the rotating block 13 is slidably connected with the surface of the front wall plate body 1 of the centrifuge. Under this action, it is convenient for the staff to rotate the rotating rod 5, thereby facilitating the adjustment of the position of the installation shell 3. A guide block 12 is fixedly connected to the other side of the installation shell 3. A guide rod 11 is fixedly connected to the inner wall of the installation groove 2. The surface of the front wall plate body 1 of the centrifuge is slidably connected with the inner wall of the guide block 12. Under this action, the installation shell 3 can be guided during movement to avoid the situation of position deviation due to the instability of the installation shell 3 during movement. Limit grooves 15 are opened at the top and bottom of both sides of the inner cavity of the installation groove 2. A positioning block 14 is slidably connected to the inner wall of the limit groove 15. One side of the positioning block 14 is fixedly connected with the surface of the installation shell 3. Under this action, the installation shell 3 can be limited during movement.When it moves, there will be no large - scale position deviation, so that the positions of the two mounting shells 3 can be more accurate when they are spliced.

[0023] It should be noted that technical features such as the centrifuge front wall plate body 1 proposed in this technical solution should be regarded as prior art. For the specific structures, working principles, possible control methods, and spatial arrangement methods of these technical features, conventional selections in this field can be adopted, and this technical solution will not be further elaborated specifically.

[0024] Working principle: First, when the front wall plate needs to be adjusted, the staff uses an auxiliary tool to rotate the rotating block 13. Immediately afterwards, the rotating block 13 will drive the first bevel gear 6 to rotate through the rotating rod 5. Immediately afterwards, the first bevel gear 6 will drive the threaded rod 8 to move through the second bevel gear 7, and under the action of the surface thread, it will drive the sleeve 4 to move, so as to move the two mounting shells 3. With the cooperation of the guide rod 11 and the guide block 12, the mounting shell 3 will move more stably until the two mounting shells 3 are spliced together, and then it starts to be used. When the mounting shell 3 needs to be moved back to its original position, reverse - rotate the rotating block 13 to move the mounting shell 3 into the installation groove 2.
