Description

Technical Field

[0002] Steel fiber refers to fibers with an aspect ratio of 40 to 80 produced by cutting fine steel wires, shearing cold-rolled strip steel, milling steel ingots, or rapid cooling of molten steel. The properties of steel fibers produced by different methods are also different. In the production process, a steel fiber screening machine is required. The main function of the steel fiber screening machine is to use an effective structure to screen the steel fibers required by the user, thereby improving the classification efficiency of steel fibers to a certain extent, thus ensuring the accuracy and safety performance of processed steel.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1-5 This utility model provides a technical solution: a steel fiber screening machine, including a dual-shaft motor 4 installed in a conical part 5. The dual-shaft motor 4 can drive both ends to rotate simultaneously, which facilitates screening while adding materials. The steel fiber screening machine includes: a feed frame 1 and a stirring blade 8. A screening cylinder 2 is inserted into the lower end of the feed frame 1. A partition cylinder 3 is inserted into the lower end of the screening cylinder 2. A discharge frame 18 or another screening cylinder 2 is inserted into the lower end of the partition cylinder 3. When multiple screenings are required, the partition cylinder 3 and the screening cylinder 2 can be added, thereby improving the overall screening quality. At the same time, the device mostly adopts plug-in connection, which facilitates the disassembly and cleaning of some screen plates 17.

[0021] The device can be quickly assembled and disassembled by plugging it in. After the installation is completed, the dual-axis motor 4 is started to make the whole device start working.

[0022] A connecting plate 6 is fixedly connected to the inner wall of the feed frame 1. The other side of the connecting plate 6 is fixedly connected to the surface of the conical part 5. The conical part 5 is fixed by the connecting plate 6, and the feed port can be divided into multiple channels. A dual-shaft motor 4 is fixedly connected to the inner wall of the conical part 5. A connecting rod 9 is fixedly connected to the upper output end of the dual-shaft motor 4. The other end of the connecting rod 9 passes through the upper end of the conical part 5 and is fixedly connected to a rotating column 7. When the dual-shaft motor 4 is started, the rotating column 7 can be driven to rotate through the connecting rod 9. Two stirring blades 8 are fixedly connected to the surface of the rotating column 7. The rotating column 7 is rotatably connected to the upper end of the conical part 5. When the rotating column 7 rotates, it can drive the stirring blades 8 to rotate. At this time, when material is added to the feed frame 1, the stirring blades 8 can make the material enter the screening cylinder 2 while being stirred, so that the material is evenly distributed on the surface of the screen plate 17, thereby making the screening more uniform.

[0023] When materials are added, the dual-shaft motor 4 will stir the materials through the stirring blades 8, so that the materials are scattered more fully and evenly, thereby improving the screening efficiency.

[0024] A gear 10 is fixedly connected to the output end of the dual-shaft motor 4 away from the stirring blade 8. The dual-shaft motor 4 can drive the gear 10 to rotate. An internal gear column 13 is meshed with the surface of the gear 10. When the gear 10 rotates, the internal gear column 13 will rotate accordingly. A rotating rod 15 is fixedly connected to the surface of the internal gear column 13. A brush plate 16 is slidably connected to the lower side of the surface of the rotating rod 15. When the internal gear column 13 rotates, the rotating rod 15 and the brush plate 16 will rotate synchronously with it. The lower end of the brush plate 16 contacts the upper end of the sieve plate 17. The rotation of the brush plate 16 increases the screening speed.

[0025] When the dual-shaft motor 4 drives the gear 10 to rotate, the gear 10 will drive the brush plate 16 to rotate through the internal gear column 13. Through the contact between the brush plate 16 and the screen plate 17, the material is quickly screened.

[0026] The inner wall of the screening cylinder 2 is provided with a limiting groove 14. The inner wall of the limiting groove 14 is slidably connected to the end of the rotating rod 15 away from the internal gear column 13 to improve smoothness. The inner wall of the partition cylinder 3 is fixedly connected to the screen plate 17. When it is necessary to clean a specific screen plate 17, the partition cylinder 3 can be removed, making disassembly easier. The lower end of the internal gear column 13 is fixedly connected to a connecting column 12. The lower end of the connecting column 12 passes through the screen plate 17 and is fixedly connected to a gear 11. When the gear 10 rotates, the connecting column 12 will drive the gear 11 to start rotating under the action of the internal gear column 13. The gear 10 and the gear 11 are the same size to facilitate operation. The surface of the connecting column 12 is rotatably connected to the screen plate 17, and the screen plate 17 is sleeved on the surface of the internal gear column 13.

[0027] In actual use, after checking that the device is correct, start the dual-shaft motor 4 and slowly pour the steel fiber material into the feed frame 1 from the upper opening. At this time, the stirring blade 8 will rotate to evenly disperse the steel fiber material into the feed frame 1. When the steel fiber material reaches the surface of the screen plate 17, the brush plate 16 will sweep the steel fiber material when it rotates, thereby accelerating the speed at which the steel fiber passes through the screen plate 17. After screening is completed, the steel fiber will flow out from the lower opening of the discharge frame 18. The device is easy to disassemble and has high screening efficiency.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
