Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of carbon additive, specifically, especially relates to a carbon additive granularity subdivision device. BACKGROUND

[0002] In the metal smelting and processing industry, carbon additive plays a very important role, and its main function is to supplement carbon elements for metal melt, thereby significantly improving the performance of metal materials, such as improving the hardness, strength and wear resistance of steel. However, with the continuous evolution of modern industrial technology towards high precision and high performance, the particle size requirement of carbon additive is increasingly strict, and its particle size subdivision has multiple key meanings.

[0003] The existing carbon additive subdivision device mostly relies on a screen to realize particle size screening. This traditional screening method exposes many serious problems in actual application. When the carbon additive is subdivided, the particle shape of the carbon additive is irregular, which easily causes the screen mesh to be blocked in the subdivision process. Once the screen mesh is blocked, the screening process of the carbon additive will be greatly hindered, and the particle size classification cannot be smoothly carried out through the screen mesh, which not only directly affects the screening effect of the carbon additive, but also makes the particle size distribution of the final carbon additive product difficult to meet the high precision requirement, and also significantly reduces the subdivision efficiency of the carbon additive.

[0004] For the problems in the related art, no effective solution has been proposed so far. CONTENT OF THE UTILITY MODEL

[0005] In view of the problems in the related art, the utility model provides a carbon additive granularity subdivision device to overcome the above technical problems existing in the prior art.

[0006] To solve the above technical problems, the utility model is realized by the following technical scheme:

[0007] The utility model is a kind of carbon additive granularity subdivision device, including base, the top of base is fixedly installed with a plurality of springs, the top of a plurality of spring is fixedly installed with shell, a plurality of the spring is located at the bottom four corners of the shell respectively, the inside of shell is equipped with first screen powder net and second screen powder net, the top of shell is equipped with vibration motor, the inside of shell and below the first screen powder net and the second screen powder net are equipped with moving mechanism, the bottom of moving mechanism near the first screen powder net and the second screen powder net is equipped with cleaning mechanism, the one end of shell and the side of first screen powder net and second screen powder net and the bottom of shell are equipped with discharge port.

[0008] Further, the top of the shell is communicated with a feeding port, and a shielding plate is rotatably installed in the discharge port at one end of the shell and on one side of the first and second screen meshes.

[0009] Further, the first and second screen meshes are both inclined and gradually decrease towards the discharge port, and the mesh holes of the first screen mesh are slightly larger than those of the second screen mesh.

[0010] Further, the moving mechanism comprises a driving motor fixedly installed on the shell, an output shaft fixedly installed at the output end of the driving motor, and a first synchronous wheel fixedly installed at the other end of the output shaft.

[0011] Further, a synchronous belt is rotatably installed on the circumferential surface of the first synchronous wheel, and a second synchronous wheel is rotatably installed at the other end of the synchronous belt.

[0012] Further, the two cleaning mechanisms both comprise a connecting rod fixedly installed on the synchronous belt.

[0013] Further, the two connecting rods are respectively located below the first and second screen meshes, and a plurality of cleaning hairs are fixedly installed at one end of each of the two connecting rods.

[0014] The present application has the following advantages:

[0015] 1. In the screening process, the moving mechanism drives the cleaning mechanism to move below the first and second screen meshes.

[0016] 2. The mesh holes of the first screen mesh are slightly larger than those of the second screen mesh and are both inclined and gradually decrease towards the discharge port, so that the larger carbon additive particles cannot pass through the mesh holes of the first screen mesh and move along the inclined surface of the first screen mesh to the corresponding discharge port side and are finally discharged; the medium-sized carbon additive particles can pass through the first screen mesh but are blocked by the second screen mesh, so as to move between the first and second screen meshes to the corresponding discharge port; and the smaller carbon additive particles pass through the first and second screen meshes in turn and are discharged from the discharge port at the bottom of the shell, so as to realize three-stage particle size screening of the carbon additive.

[0017] Of course, implementing any product of the utility model does not necessarily need to achieve all the advantages mentioned above at the same time. BRIEF DESCRIPTION OF DRAWINGS

[0027] The technical solutions in the utility model embodiments will be described clearly and completely below with reference to the drawings in the utility model embodiments. Obviously, the described embodiments only constitute some of the utility model embodiments, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of the utility model protection.

[0028] In the description of the utility model, it is understood that the terms "opening", "upper", "lower", "top", "middle", "inner" and the like indicate the orientation or positional relationship, which is only for the convenience of describing the utility model and simplifying the description, and is not intended to indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0029] Please refer to Figures 1-6 The utility model discloses a kind of carbon additive granularity subdivision devices, including base 1, the top of the base 1 is fixedly installed with multiple springs 2, the top of multiple spring 2 is fixedly installed with shell 3, multiple spring 2 is respectively located at the bottom four corners of shell 3, the inside of shell 3 is equipped with first powder screen 4 and second powder screen 5, the top of shell 3 is equipped with vibration motor 6, the inside of shell 3 and below first powder screen 4 and second powder screen 5 are equipped with moving mechanism 7, the bottom of moving mechanism 7 is close to first powder screen 4 and second powder screen 5 and is equipped with cleaning mechanism 8, one end of shell 3 and located at the side of first powder screen 4 and second powder screen 5 and the bottom of shell 3 are equipped with discharge port 9.

[0030] The first powder screen 4 and the second powder screen 5 are both inclined, and gradually decrease towards the direction of the discharge port 9.

[0031] After starting vibration motor 6, the vibration force generated by vibration motor 6 is transmitted to shell 3, since shell 3 bottom is connected with base 1 through spring 2, spring 2 not only plays a role in supporting shell 3, but also can enhance and adjust vibration effect in the process of vibration, so that shell 3 and the first powder screen 4 and the second powder screen 5 inside it produce suitable high-frequency vibration, pour the carbon additive to be screened into shell 3, under the action of vibration, the carbon additive keeps rolling and sliding on the inclined first powder screen 4 and second powder screen 5, since the mesh of the first powder screen 4 is slightly larger than the mesh of the second powder screen 5 and they are both inclined and gradually decrease towards the direction of the discharge port 9, the larger particles of the carbon additive cannot pass through the mesh of the first powder screen 4 and gradually move along the inclined surface thereof to the side of the corresponding discharge port 9 and are finally discharged; the medium particles of the carbon additive can pass through the first powder screen 4 but are blocked by the second powder screen 5, so as to move between the first powder screen 4 and the second powder screen 5 to the corresponding discharge port 9 and be discharged; and the smaller particles of the carbon additive pass through the first powder screen 4 and the second powder screen 5 in turn, and are discharged from the discharge port 9 at the bottom of shell 3, so as to realize three-stage particle size screening of the carbon additive.

[0032] During the screening process, the moving mechanism 7 drives the cleaning mechanism 8 to move below the first powder screen 4 and the second powder screen 5. When the carbon additive is blocked in the screen mesh due to irregular particle shape or other reasons, the cleaning mechanism 8 can clean the mesh, thereby timely unblocking the mesh of the first powder screen 4 and the second powder screen 5, ensuring that the screening efficiency and effect of the first powder screen 4 and the second powder screen 5 are not affected, ensuring that the entire carbon additive particle size subdivision process can be continuously, efficiently and accurately carried out, meeting the requirements for fine classification of carbon additive particle size, so as to better play a role in metal smelting and processing and improve the performance of metal materials.

[0033] In one embodiment, for the above-mentioned shell 3, the top of the shell 3 is communicated with a feeding port 301, and a blocking plate 302 is rotatably installed in the discharge port 9 at one end of the shell 3 and on one side of the first powder screen 4 and the second powder screen 5.

[0034] The carbon additive is conveyed into the shell 3 through the feeding port 301, and under the action of the vibration motor 6 and the screening of the first powder screen 4 and the second powder screen 5, carbon additives of different particle sizes move to the corresponding discharge port 9, and the discharge port 9 on one side of the first powder screen 4 and the second powder screen 5 is used to discharge the carbon additive of large or medium particle size intercepted by the corresponding screen. The blocking plate 302 is rotatably installed in the discharge port 9, and in the normal screening process, the carbon additive can drive the blocking plate 302 to rotate, and when the device is in a non-screening state, the blocking plate 302 can effectively shield the discharge port 9. In turn, prevent foreign matter from entering the shell 3 through the discharge port 9 in the reverse direction during the idle period of the device.

[0035] In one embodiment, for the above-mentioned moving mechanism 7, the moving mechanism 7 comprises a driving motor 701, the driving motor 701 is fixedly installed on the shell 3, the output end of the driving motor 701 is fixedly installed with an output shaft 702, and the other end of the output shaft 702 is fixedly installed with a first synchronous wheel 703.

[0036] The circumferential surface of the first synchronous wheel 703 is rotatably installed with a synchronous belt 704, the other end of the synchronous belt 704 is rotatably installed with a second synchronous wheel 705, and the second synchronous wheel 705 is rotatably installed on the shell 3.

[0037] Both of the cleaning mechanisms 8 comprise a connecting rod 801, and the connecting rod 801 is fixedly installed on the synchronous belt 704.

[0038] Both of the connecting rods 801 are located below the first powder screen 4 and the second powder screen 5, and one end of each of the connecting rods 801 is fixedly installed with a plurality of cleaning hairs 802.

[0039] When the first screen powder net 4 and the second screen powder net 5 need to be cleaned, the driving motor 701 is started, the driving motor 701 drives the output shaft 702 to rotate, and then the first synchronous wheel 703 fixed on the output shaft 702 rotates. The rotation of the first synchronous wheel 703 is transmitted to the second synchronous wheel 705 through the synchronous belt 704, so that the synchronous belt 704 rotates circularly between the first synchronous wheel 703 and the second synchronous wheel 705. Since the two connecting rods 801 are fixed on the synchronous belt 704 on the respective sides and correspondingly located below the first screen powder net 4 and the second screen powder net 5, taking the cleaning of the first screen powder net 4 as an example, with the rotation of the synchronous belt 704, the connecting rod 801 will move linearly along the bottom of the first screen powder net 4. The plurality of cleaning hairs 802 are made of soft material, and in the moving process, the plurality of cleaning hairs 802 fixed on one end of the connecting rod 801 are cleaned out by mutual friction and scraping with the mesh hole wall of the first screen powder net 4 and the carbon additive particles blocked in the mesh hole, so that the mesh hole of the first screen powder net 4 is restored to unobstructed, thereby ensuring that the carbon additive can be smoothly screened on the screen, effectively solving the problems of reduced screening effect and reduced fine division efficiency caused by the carbon additive blocking the screen.
