Description

Technical Field

[0001] The utility model belongs to the technical field of spheroidizing agent screening, and particularly relates to a spheroidizing agent screening device. Background Technique

[0002] An additive that makes the graphite in cast iron crystallize into spherical shapes is called a "spheroidizing agent". The main components of the "spheroidizing agent" are spheroidizing elements such as Mg, Ce, Ca, etc. The spherical graphite in ductile iron is formed after the cast iron liquid is spheroidized, which makes its strength much higher than that of gray cast iron, and its toughness is better than that of malleable cast iron. At the same time, it can also maintain a series of advantages of gray cast iron. However, the "spheroidizing agent" used in the melting and casting of ductile iron can increase the tendency of the weld to produce "white mouth" and hardened structure, and induce cracks in the weld and the heat affected zone (especially the fusion zone). Therefore, the weldability of ductile iron is worse than that of gray cast iron.

[0003] In the field of casting, the development of spheroidizing agents plays an important role in promoting the production of ductile iron, so it has received more and more attention. In industry, large lumps of spheroidizing agents need to be broken into appropriate particle sizes before use to achieve the desired spheroidizing effect. Therefore, screening equipment is required to screen the spheroidizing agents to obtain spheroidizing agents with appropriate diameters. However, current screening devices often directly perform screening operations through a sieve mesh or a sieve plate with holes. Some material particles may be almost the same as the inner diameter of the mesh holes, and the mesh holes may be blocked during the screening process. More mesh holes will be blocked after long-term use, affecting the working efficiency of the screening operation. Content of the Utility Model

[0004] The utility model provides a spheroidizing agent screening device, aiming to solve the problem that some material particles may be almost the same as the inner diameter of the mesh holes, and the mesh holes may be blocked during the screening process.

[0007] The screening box mechanism includes an upper box body with openings at both the top and bottom. The bottom end of the upper box body is detachably installed with a lower box body with an open top and adapted to the inner contour of the placement box. Horizontally penetrating through the outer surface of the upper box body are a plurality of vertically arranged sliding grooves. Vertically slidably connected inside each of the plurality of sliding grooves is a sliding block with its outer end extending to the outside of the lower box body. The inner ends of the plurality of sliding blocks are fixedly connected with a screening plate adapted to the inner contour of the upper box body.

Specific embodiments

[0019] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution: a spheroidizing agent screening device, including a floor 1 and a screening box mechanism;

[0021] The upper surface of the floor 1 is fixedly connected with a first fixed seat 2. The top end of the first fixed seat 2 is horizontally rotatably connected with a connection block 3. The top end of the connection block 3 is fixedly connected with a placement box 4 with an open top. The screening box mechanism is detachably installed inside the placement box 4;

[0022] The screening box mechanism includes an upper box body 8 with open top and bottom. The bottom end of the upper box body 8 is detachably installed with a lower box body 9 with an open top and adapted to the inner contour of the placement box 4. Horizontally penetrating through the outer surface of the upper box body 8 are provided a plurality of vertically arranged sliding grooves 10. Vertically slidably connected inside the plurality of sliding grooves 10 are sliding blocks 11 with their outer ends extending outside the lower box body 10. The inner ends of the plurality of sliding blocks 11 are fixedly connected with a screening plate 13 adapted to the inner contour of the upper box body 8. Vertically fixedly connected to the bottom end inside the lower box body 9 are a plurality of vertical rods 14 extending upward into the upper box body 8 and corresponding to the plurality of holes of the screening plate 13.

[0023] Vertically fixedly connected to the outer surface of the upper box body 8 are a plurality of second electric control telescopic rods 12. The top ends of the plurality of second electric control telescopic rods 12 are respectively fixedly connected to the bottom ends of the plurality of sliding blocks 11.

[0024] The outer diameter of the cross-section of each of the plurality of vertical rods 14 is smaller than the inner diameter of the plurality of holes of the screening plate 13.

[0025] In this embodiment, the device screens the spheroidizing agent material through the screening box mechanism. During the screening process, multiple second electric control telescopic rods 12 on the outer surface of the screening box mechanism will synchronously extend and contract. During the extension and contraction process, the screening plate 13 will be driven to move synchronously, driving the material located inside the upper box body 8 to flow, enabling the qualified material to fall through the holes on the screening plate 13 and be screened out. At the same time, during the downward movement of the screening plate 13, if there is material stuck on the holes, it will be poked upward by the vertical rod 14 inside the lower box body 9, thereby preventing the holes from being blocked and ensuring the efficiency of the screening operation.

[0026] When multiple second electric control telescopic rods 12 extend and contract synchronously, they will drive multiple sliding blocks 11 to move synchronously upward and downward, and the multiple sliding blocks 11 will drive the screening plate 13 fixedly connected to their inner ends to move synchronously.

[0027] Furthermore, one end of the upper surface of the platform 1 is fixedly connected with a second fixed seat 5. The top end of the second fixed seat 5 is horizontally rotatably connected with a first electric control telescopic rod 6. The other end of the first electric control telescopic rod 6 is rotatably connected with a connecting seat 7, and the other end of the connecting seat 7 is fixedly connected to the outer surface of the placement box 4.

[0028] In this embodiment, during the screening operation, the first electric control telescopic rod 6 will also continuously extend and contract in a reciprocating motion, thereby being able to push the placement box 4 to swing back and forth, making the material inside the screening box mechanism easier to be screened down and improving the efficiency of the screening operation.

[0029] Furthermore, the bottom end of the lower box body 9 is vertically fixedly connected with multiple magnetic rods 15.

[0030] The bottom end of the placement box 4 is vertically and throughly provided with multiple installation holes respectively corresponding to the multiple magnetic rods 15, and the inner parts of the multiple installation holes are respectively fixedly connected with magnetic rings 16 that mutually attract the multiple magnetic rods 15.

[0031] In this embodiment, the screening box mechanism is detachably installed inside the placement box 4 through the magnetic rods 15 and the magnetic rings 16. After the screening operation is completed, it is convenient to remove the entire screening box mechanism, and then remove the lower box body 9 to collect the screened material.

[0032] Working principle and usage process of the utility model: After the utility model is installed, the device screens the spheroidizing agent material through the screening box mechanism. During the screening process, multiple second electric control telescopic rods 12 on the outer surface of the screening box mechanism will synchronously extend and contract. During the extension and contraction process, the screening plate 13 is driven to move synchronously, which will drive the material located inside the upper box body 8 to flow, enabling the material that meets the specifications to fall through the holes on the screening plate 13 and be screened out. At the same time, during the downward movement of the screening plate 13, if there is material stuck on the holes, it will be poked up by the vertical rod 14 inside the lower box body 9, thereby preventing the holes from being blocked and ensuring the efficiency of the screening operation.

[0033] The above are only the preferred embodiments of the utility model and are not intended to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
