Description

Technical Field

[0001] The utility model relates to the field of screening baskets, in particular to a modular and quickly installed screening basket. Background Art

[0002] At present, the existing centrifuge screening basket is an integral structure, in a frustum shape, mainly composed of an upper flange, a lower flange, reinforcing ribs, a reinforcing ring, and a stainless steel conical mesh cylinder. In order to reduce the blockage of the screening slits of the screening basket, generally the screening slits are made smaller at the top and larger at the bottom. During operation, the centrifuge screening basket rotates at a high speed, and the material enters the screening basket from the upper end of the screening basket for dehydration. The screening slits in the upper half of the screening basket are small and there is a lot of material, so the impact force and friction force of the material, water, etc. are much greater than those in the lower half of the screening basket. In practical applications, there is a phenomenon that the upper half of the screening basket is severely damaged and needs to be replaced, but the lower half of the screening basket is still intact and can still be used for a long time. Therefore, there is an obvious difference in the service life of the upper and lower parts of the centrifuge screening basket. Due to the limitation of the integral structure of the centrifuge screening basket, even if the lower half of the screening basket is intact, as long as the upper half is severely damaged, during maintenance, the entire screening basket must be removed and replaced, resulting in a waste of the maintenance cost of the screening basket.

[0003] Chinese authorized publication number CN203342951U discloses a centrifuge screening basket that can be disassembled, which is a key component in centrifuge dehydration equipment. It can be disassembled into two major parts, namely the upper centrifuge screening basket and the lower centrifuge screening basket, mainly composed of an upper flange, a middle flange, a lower flange, a bottom flange, connecting bolts, sealing gaskets, reinforcing ribs, a reinforcing ring, and a stainless steel conical mesh cylinder. The upper and lower parts of the centrifuge screening basket are connected into one body through the connecting bolts on the upper middle flange and the lower middle flange, and the two parts of the centrifuge screening basket can be selectively maintained and replaced according to the differences in wear conditions.

[0004] However, this device has the following defects in use: Although this device can divide the screening basket into two parts for replacement, the stainless steel conical mesh cylinders on the upper and lower parts are still integral. When a certain part of the stainless steel conical mesh cylinders on the upper and lower parts is damaged, the whole still needs to be replaced. In view of the above defects, for this reason, we propose a modular and quickly installed screening basket. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a modular and quickly installed screening basket.

[0006] To solve the problems existing in the prior art, the present utility model adopts the following technical solutions: A modular and quickly installable sieve basket includes a plurality of conical support frames connected to each other in equal proportion, and a sieve mesh disposed inside the plurality of conical support frames. The conical support frame includes an upper flange plate, a lower flange plate, and reinforcing ribs disposed between the upper flange plate and the lower flange plate, and an assembly structure is provided between the conical support frame and the sieve mesh;

[0007] The assembly structure includes an assembly plate and grooves formed on the surface of the reinforcing ribs, and bolt holes are formed on the inner wall of the grooves, the surface of the assembly plate, and the surface of the reinforcing ribs.

[0008] Preferably, a rectangular groove for the passage of materials is formed on the surface of the assembly plate.

[0009] Preferably, the upper end of the reinforcing rib is fixedly connected to the lower surface of the upper flange plate, and the lower end of the reinforcing rib is fixedly connected to the upper surface of the lower flange plate.

[0010] Preferably, through holes for the passage of fasteners are formed on the surfaces of the upper flange plate and the lower flange plate.

[0011] Preferably, the number of the reinforcing ribs is multiple, and the multiple reinforcing ribs are arranged at equal intervals between the upper flange plate and the lower flange plate.

[0012] Preferably, the grooves on two adjacent reinforcing ribs are adapted to the size of the sieve mesh.

[0013] Preferably, the sieve mesh is composed of a limiting frame and a mesh plate fixedly installed on the inner wall of the limiting frame.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] By providing the assembly structure, the sieve mesh is placed in the grooves between two adjacent reinforcing ribs, then the assembly plate is placed into the grooves, and then external bolts are screwed into the bolt holes, so that the assembly plate, the sieve mesh, and the reinforcing ribs can be fixed together to form a small sieve basket. Then, multiple conical support frames are stacked on each other, and then external fasteners pass through the through holes, so that the multiple conical support frames can be fixed together to form an overall sieve basket. Compared with the prior art, in this device, multiple sieve meshes in the conical support frames can be fixed between two adjacent reinforcing ribs by using the assembly components, and then the upper flange plates and the lower flange plates on two adjacent conical support frames can be fixed together by using external fasteners to form an overall sieve basket. Furthermore, after the sieve mesh at a certain position is damaged, only a small area of it can be disassembled, which not only reduces the replacement cost but also enables quick disassembly and installation.

[0016] By setting up a sieve mesh, multiple sieve meshes are arranged inside the conical support frame, which can reduce the surface area of a single sieve mesh. When an external force acts on it, the force on the sieve mesh is more concentrated, avoiding local deformation or damage that is likely to occur, and increasing the stability of the sieve mesh in the overall structure.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention.

[0025] Please refer to Figures 1-5 , the present invention provides a technical solution: a modular and quickly installable sieve basket, including a plurality of conical support frames connected to each other in equal proportion, and a sieve mesh arranged inside the plurality of conical support frames. The conical support frame includes an upper flange plate 1, a lower flange plate 2, and a reinforcing rib 3 arranged between the upper flange plate 1 and the lower flange plate 2. The upper end of the reinforcing rib 3 is fixedly connected to the lower surface of the upper flange plate 1, and the lower end of the reinforcing rib 3 is fixedly connected to the upper surface of the lower flange plate 2. The number of the reinforcing ribs 3 is multiple, and the multiple reinforcing ribs 3 are equidistantly arranged between the upper flange plate 1 and the lower flange plate 2. The upper flange plate 1 and the lower flange plate 2 can be fixed into one body by using the reinforcing rib 3.

[0026] Through holes 8 for fasteners to pass through are provided on the surfaces of the upper flange plate 1 and the lower flange plate 2. Stack multiple conical support frames on top of each other, and then use external fasteners to pass through the through holes 8, so that multiple conical support frames can be fixed together to form an integral frame. When a certain conical support frame is damaged, it can be replaced without replacing the whole.

[0027] The sieve is composed of a limit frame 9 and a mesh plate 10 fixedly installed on the inner wall of the limit frame 9. The limit frame 9 can support and shape the mesh plate 10.

[0028] An assembly structure is provided between the conical support frame and the sieve. The assembly structure includes an assembly plate 4 and a groove 5 opened on the surface of the reinforcing rib 3. The grooves 5 on two adjacent reinforcing ribs 3 are adapted to the size of the sieve. A rectangular groove 7 for materials to pass through is opened on the surface of the assembly plate 4, and bolt holes 6 are opened on the inner wall of the groove 5, the surface of the assembly plate 4 and the surface of the reinforcing rib 3.

[0029] Place the sieve in the groove 5 between two adjacent reinforcing ribs 3, then put the assembly plate 4 into the groove 5, and then use an external bolt to pass through the threaded holes 6 on the assembly plate 4 and the limit frame 9 and screw it into the bolt hole 6 in the groove 5, so that the assembly plate 4, the sieve and the reinforcing rib 3 can be fixed together to form a small sieve basket.

[0030] Setting multiple sieves inside the conical support frame can reduce the surface area of a single sieve, making the force on the sieve more concentrated when it is subjected to external forces, avoiding local deformation or damage, and thus increasing the stability of the sieve in the overall structure.

[0031] Compared with the prior art, this device can fix multiple sieves inside the conical support frame between two adjacent reinforcing ribs 3 by using an assembly component, and then use external fasteners to fix the upper flange plate 1 and the lower flange plate 2 on two adjacent conical support frames together to form an integral sieve basket. Furthermore, after a sieve at a certain position is damaged, only a small area of it can be disassembled, which not only reduces the replacement cost, but also enables quick disassembly and installation.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent replacement or change made by those skilled in the art according to the technical solution and concept of the present invention should be covered by the protection scope of the present invention.
