Description

Technical Field

[0001] The utility model relates to the technical field of filter components for centrifuges, in particular to a filter component suitable for large-particle-size solid particles. Background Art

[0002] A centrifuge is a common mechanical device that uses centrifugal force to separate substances into components with different densities. Centrifuges are widely used in various fields, including medicine, chemical industry, food processing, environmental protection, etc.

[0003] Chinese Patent Publication No. CN218890696U discloses a centrifuge. Through a detachable filter cylinder, the extraction of naphthoic acid becomes more convenient after the centrifugation process. The stability inside the machine during the separation work can be ensured through the chute opened at the bottom of the sealing plate, and the working efficiency is improved.

[0004] In the above technical solution, solid-liquid separation of materials is carried out through a detachable filter cylinder during use. However, during use, since particulate materials remain in the filter cylinder and are easily attached to the inner wall of the filter cylinder under the influence of centrifugal force during rotation, it not only easily clogs the filter screen on the filter cylinder, but also takes a lot of time for separation after a thick accumulation, which is inconvenient to use. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a filter component suitable for large-particle-size solid particles.

[0006] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0007] A filter component suitable for large-particle-size solid particles includes a filter frame. A bearing plate is arranged below the middle part inside the filter frame. A filter screen is arranged at the top end of the bearing plate. A chassis is fixed in the middle of the inner top end of the filter frame. A plurality of groups of contact blocks are evenly installed at the top end of the chassis. The contact blocks are in an inclined structure. A plurality of groups of moving components are equidistantly connected to the bearing plate, and each group of the moving components is misaligned with the contact blocks. The moving component includes a guide rod slidably connected to the bearing plate. A ball is rotatably connected to the bottom end of the guide rod, and there is a gap between the ball and the top end of the chassis. A telescopic spring is fixed in the middle of the top end of the guide rod, and a top plate is fixed at the top end of the telescopic spring.

[0008] Preferably, an empty slot for bearing the moving component is opened on the chassis, and the size of the top plate is smaller than the size of the empty slot.

[0009] Preferably, a limit sleeve is installed below the empty slot, and the inner diameter of the limit sleeve is larger than the diameter of the guide rod.

[0010] Preferably, a convex block is fixed on the outer side of the top end of the guide rod, and the outer diameter of the convex block is larger than the inner diameter of the limit sleeve and smaller than the inner diameter of the empty groove.

[0011] Preferably, a sliding seat is installed on the outer side of the bearing plate, and a sliding groove for carrying the sliding seat is formed on the filter rack.

[0012] Preferably, a plurality of groups of guide blocks are evenly installed on the outer side of the filter screen, and connecting grooves corresponding to the guide blocks are formed on the filter rack. The filter screen and the filter rack are connected through the guide blocks and the connecting grooves.

[0013] Preferably, the diameter of the filter holes on the filter rack is larger than the diameter of the filter holes on the filter screen.

[0014] Preferably, a connecting cavity is formed at the bottom end of the filter rack, and the connecting cavity has a polygonal structure.

[0015] The beneficial technical effects are as follows:

[0016] By providing the chassis, the contact block and the moving component, the filter rack can drive the chassis to rotate, and then drive the contact block to rotate. During the rotation of the contact block, the contact block can contact the guide rod in the moving component, and the ball at the bottom end of the guide rod rolls under the influence of friction. During the contact between the guide rod and the inclined contact block, the guide rod receives an upward thrust, driving the telescopic spring and the top plate to contact the filter screen. By contacting the filter screen, the filter screen generates a certain vibration, so that the granular materials attached to the inner wall can be separated. This not only prevents the filter component from being blocked, but also can effectively reduce the subsequent separation time, facilitating use. Description of the Drawings

[0024] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below in conjunction with the embodiments and the accompanying drawings. However, the implementation manners of the present utility model are not limited thereto.

[0025] As Figures 1-5 shown, the filtration assembly applicable to large-particle-size solid particles provided in this embodiment includes a filter rack 1. Below the middle part inside the filter rack 1, there is a bearing plate 3 for bearing a filter screen 4. A filter screen 4 is arranged at the top of the bearing plate 3. The filter screen 4 can effectively separate particulate materials and liquid materials. In the middle of the top inside the filter rack 1, a chassis 5 is fixed. The bottom plate can support the contact block 6. A plurality of groups of contact blocks 6 are evenly installed on the top of the chassis 5. When the contact block 6 contacts the guide rod 701, the guide rod 701 can be forced to displace. The contact block 6 is of an inclined structure, and a plurality of groups of moving components 7 are equidistantly connected on the bearing plate 3, and each group of moving components 7 is misaligned with the contact block 6. The moving component 7 includes a guide rod 701 slidably connected to the bearing plate 3. The guide rod 701 can drive the telescopic spring 703 and the top plate 704 to displace. At the bottom end of the guide rod 701, a ball 702 is rotatably connected. The ball 702 can prevent the guide rod 701 from directly colliding with the contact block 6, and there is a gap between the ball 702 and the top of the chassis 5. In the middle of the top end of the guide rod 701, a telescopic spring 703 is fixed. The telescopic spring 703 can drive the top plate 704 and the guide rod 701 to quickly reset. At the top of the telescopic spring 703, a top plate 704 is fixed. The top plate 704 can contact the filter screen 4 to make it vibrate.

[0026] As Figure 5 shown, an empty groove 8 for bearing the moving component 7 is formed on the chassis 5, and the size of the top plate 704 is smaller than the size of the empty groove 8, which is convenient for the vertical movement of the guide rod 701, the telescopic spring 703 and the top plate 704 in the empty groove 8.

[0027] As Figure 5 shown, a limit sleeve 9 is installed below the empty groove 8, and the inner diameter of the limit sleeve 9 is larger than the diameter of the guide rod 701, which is convenient for guiding the guide rod 701 through the limit sleeve 9.

[0028] As Figures 4-5As shown, a convex block 10 is fixed on the outer side of the top end of the guide rod 701. The outer diameter of the convex block 10 is larger than the inner diameter of the limit sleeve 9 and smaller than the inner diameter of the empty groove 8, so that the guide rod 701 can be prevented from disengaging from the bearing plate 3 through the convex block 10.

[0029] As Figures 2-3 shown, a sliding seat 11 is installed on the outer side of the bearing plate 3, and a sliding groove for bearing the sliding seat 11 is provided on the filter rack 1, enabling the bearing plate 3 to rotate along the filter rack 1 through the sliding seat 11. However, there is a speed difference between the bearing plate 3 and the filter rack 1 during the movement.

[0030] As Figures 1-3 shown, a plurality of groups of guide blocks 12 are evenly installed on the outer side of the filter screen 4, and connection grooves 13 are provided on the filter rack 1 corresponding to the guide blocks 12. The filter screen 4 and the filter rack 1 are connected through the guide blocks 12 and the connection grooves 13, facilitating the installation of the filter screen 4 in the filter rack 1 through the guide blocks 12 and the connection grooves 13.

[0031] As Figures 1-3 shown, the diameter of the filter holes on the filter rack 1 is larger than the diameter of the filter holes on the filter screen 4, facilitating the multi-stage separation and filtration of materials.

[0032] As Figures 1-2 shown, a connection cavity 2 is provided at the bottom end of the filter rack 1, and the connection cavity 2 has a polygonal structure, facilitating the centrifuge to drive the filter rack 1 to rotate.

[0033] Working principle of the device: When the device is in specific use, the filter screen 4 is installed in the filter rack 1 through the guide blocks 12 and the connection grooves 13, and then the filter rack 1 is installed in the centrifuge and connected to the driving mechanism in the centrifuge through the connection cavity 2. After the installation is completed, the material is fed into the filter screen 4. The driving mechanism in the centrifuge drives the filter rack 1 to rotate. The centrifugal force generated during the rotation can separate the particles and liquid in the material. The liquid material enters the centrifuge through the filter screen 4 and the filter rack 1 and is discharged, while the particulate material remains in the filter screen 4;

[0034] And during the use process, the bearing plate 3 rotates along the filter rack 1 through the sliding seat 11. However, there is a speed difference between the bearing plate 3 and the filter rack 1 during the movement. Therefore, the rotation speed of the chassis 5 can be greater than the rotation speed of the bearing plate 3. During the rotation process, the contact block 6 can contact the guide rod 701 in the moving component 7, and the ball 702 at the bottom end of the guide rod 701 rolls under the influence of friction. During the contact between the guide rod 701 and the inclined contact block 6, the guide rod 701 receives an upward thrust, driving the telescopic spring 703 and the top plate 704 to contact the filter screen 4. By contacting the filter screen 4, the filter screen 4 generates a certain vibration, so that the particulate material attached to the inner wall can be separated. This not only prevents the filter component from being blocked, but also can effectively reduce the subsequent separation time and facilitate the use.

[0035] The above are only further embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, making equivalent substitutions or changes according to the technical solution and its concept of the present utility model, shall fall within the protection scope of the present utility model.
