Description

Technical Field

[0001] This utility model relates to the field of slag powder screening technology, and more specifically, to a slag powder screening device. Background Technology

[0002] The slag powder screening device is a specialized piece of equipment used for particle size classification of slag powder. It mainly consists of a feeding system, a screening mechanism, a power unit, a collection bin, and a dust removal system. The screening mechanism typically uses a vibrating screen to separate coarse and fine slag powder through the screen mesh. The power unit provides vibration force for the screening process, ensuring uniform material dispersion. The dust removal system uses negative pressure adsorption to reduce dust leakage during screening, ensuring an environmentally friendly working environment. This device is widely used in building materials, metallurgy, and other industries, effectively improving the grading efficiency and product quality of slag powder. During operation, the slag powder screening device... The crushed slag powder is evenly fed into the screening mechanism by the feeding system. The power unit drives the screen to generate high-frequency vibration, causing the slag powder to be layered on the screen surface according to particle size. Fine particles pass through the screen and fall into the collection bin, while coarse particles slide along the screen surface to the waste outlet. At the same time, the dust removal system is started, and a negative pressure airflow is formed by the fan to draw the dust generated during the screening process into the dust removal pipeline. After purification treatment, the dust is discharged, realizing the integrated operation of screening and environmental protection. Since the uniformity of material distribution during the slag powder screening process directly affects the screening uniformity of the slag powder, it is necessary to carry out screening and material distribution operations.

[0003] In related technologies, during the use of screening devices, slag powder from the outside is generally added into the screening device through the top feed hopper and comes into contact with the screen so that the inclined screen can screen the slag powder for use.

[0004] However, during the current use of screening devices, due to the inherent fluidity of slag powder, when a large amount of slag powder is added to the top of the screen, uneven distribution of slag powder can easily occur, resulting in some slag powder being discharged from the screening device without being fully screened, thus affecting the uniformity of the screening material distribution and the screening effect of the screening device.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on 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.

[0030] Reference Figures 1-4 This utility model provides a technical solution: a slag powder screening device, including a screening machine 1 and a screening and feeding mechanism. A base frame 2 is installed at the bottom of the screening machine 1, and a screen 3 is installed inside the screening machine 1. The slag powder material on the top of the screen 3 can be distributed in a barrier manner, so that the slag powder is evenly distributed on the top of the screen 3, avoiding uneven distribution of slag powder and the situation where the slag powder is discharged due to insufficient screening. Therefore, the uniformity of the feeding of the screen 3 and the screening effect are improved.

[0031] Reference Figures 1-4 In a preferred embodiment, the screening and feeding mechanism includes a feeding frame 4, which is movably connected to the top of the screen 3. A clamping plate 5 is movably connected to the front side of the bottom of the feeding frame 4. Feeding columns 6 are fixedly connected to both sides of the feeding frame 4. A feeding cylinder 7 is sleeved on the surface of the feeding column 6. A feeding positioning mechanism is fixedly connected to the inner side of the top of the feeding cylinder 7. The feeding frame 4, in conjunction with the clamping plate 5, installs the feeding column 6 on the top of the screen 3. Then, according to the required feeding width, the feeding cylinder 7 is moved horizontally to adjust the feeding width of the feeding column 6. When external slag powder is added to the top of the screen 3, the feeding frame 4, in conjunction with the feeding column 6, feeds the material. The cylinder 7 is used to block and distribute the slag powder at the top of the screen 3, so that the screen 3 can fully screen the slag powder. The material positioning mechanism includes a positioning cylinder 8, a positioning column 9, and a positioning groove 10. The positioning cylinder 8 is fixedly connected to the inner side of the top of the material cylinder 7, the positioning column 9 is movably connected to the inside of the positioning cylinder 8, and the positioning groove 10 is opened at the top of the material column 6. The bottom of the positioning column 9 is located inside the positioning groove 10, which can adjust the material positioning between the material column 6 and the material cylinder 7, avoiding the difficulty in positioning the material sleeve and causing the material cylinder 7 to shift left and right. Therefore, the positioning convenience of the material cylinder 7 is improved.

[0032] Reference Figures 2-4 In a preferred embodiment, by movably connecting the top and bottom of both sides inside the positioning cylinder 8 with barrier blocks 11, the inner side of the barrier blocks 11 is fixedly connected to the outer side of the positioning post 9, which can isolate and stabilize the positioning post 9 and the positioning cylinder 8, and prevent the positioning post 9 from rising and moving away from the positioning groove 10 during operation, thus improving the working stability of the positioning post 9. The top of the inner wall of the positioning cylinder 8 is provided with misalignment openings 12 on both sides, and the barrier blocks 11 are located at the bottom of the misalignment openings 12, which can provide space for the barrier blocks 11 to move out of the positioning cylinder 8, and prevent the positioning post 9 from being affected by the position of the barrier blocks 11 during use, thus making it difficult for the positioning post 9 to move out of the positioning groove 10, thus improving the ease of operation of the barrier blocks 11.

[0033] Reference Figures 2-3In a preferred embodiment, a sliding opening 13 is provided at the bottom of the front side of the fabric frame 4, and a sliding plate 14 located in front of the sliding opening 13 is movably connected to the front side of the fabric frame 4. An anti-slip pad 15 is fixedly connected to the rear side of the sliding plate 14. This allows for stable sliding clamping between the clamping plate 5 and the fabric frame 4, preventing the clamping plate 5 from being unable to maintain a stable clamping force during use. This improves the clamping stability of the clamping plate 5. A screw groove 16 is provided on the front side of the clamping plate 5, and a stud 17 is threaded inside the screw groove 16. The front side of the stud 17 is fixedly connected to the rear side of the sliding plate 14, providing a medium for applying a clamping stabilizing force to the sliding plate 14. This improves the force application effect of the sliding plate 14.

[0034] Reference Figure 2 In a preferred embodiment, lifting frames 18 are fixedly connected to both sides of the front side of the clamping plate 5. Lifting bars 19 are movably connected inside the lifting frames 18. The inner side of the lifting bars 19 is fixedly connected to the outer side of the fabric rack 4. This allows for lifting and connecting the clamping plate 5 and the fabric placing machine to prevent deviation, thus improving the stability of the clamping plate 5. Connecting plates 20 located inside the fabric placing column 6 are movably connected to both sides of the fabric rack 4. The outer side of the connecting plates 20 is fixedly connected to the surface of the fabric cylinder 7. This allows for synchronous operation between multiple fabric cylinders 7, thus improving the connection effect between the fabric cylinders 7.

[0035] Specifically, the working process or working principle of this slag powder screening device is as follows: During use, the hand-held material feeder 4 drives the material feeder column 6 and material feeder cylinder 7 to be placed on top of the screen 3, ensuring the rear side of the bottom of the material feeder 4 contacts and abuts against the front side of the discharge hopper of the screening machine 1, and the clamping plate 5 is positioned at the bottom of the discharge hopper of the screening machine 1. Then, the hand-held sliding plate 14, in conjunction with the sliding opening 13, applies an upward moving force to the clamping plate 5 through the screw stud 17 and screw groove 16, causing the clamping plate 5 to contact the bottom of the discharge hopper of the screening machine 1. At this time, the lifting bar 19 moves inside the lifting frame 18, pressing against the clamping plate 5 and the material feeder 4. The lifting and lowering connection prevents deviation. When the clamping plate 5 moves, the hand-held slide plate 14 drives the stud 17 to rotate and engage with the screw groove 16. The threaded thrust of the slide plate 14, which moves backward, causes the slide plate 14 to drive the protective pad to contact and press against the front of the fabric frame 4. This causes the clamping plate 5 to clamp and stabilize the fabric frame 4 at the top of the screen 3. Subsequently, according to the actual fabric width requirement of the screen 3, the hand-held fabric cylinder 7 moves outside the fabric column 6 to adjust the fabric width of the fabric column 6. At this time, the connecting plate 20 moves and connects multiple fabric cylinders 7 synchronously to facilitate use. The operator simultaneously moves multiple fabric cylinders 7 for adjustment. At this time, the blocking block 11 is located at the top of the positioning cylinder 8, providing obstruction and support between the positioning post 9 and the positioning cylinder 8. After the fabric cylinder 7 is adjusted by translation, the operator holds the positioning post 9 and rotates the blocking block 11 to align with the misalignment opening 12. Then, the operator moves the positioning post 9 downwards and inserts it into the positioning groove 10, performing insertion and positioning between the adjusted fabric cylinder 7 and the fabric post 6. At this time, the blocking block 11 follows the positioning post 9 through the misalignment opening 12, penetrates the positioning cylinder 8, and enters the interior of the positioning cylinder 8. The operator then holds the positioning post 9 and rotates the blocking block 11 to align with the misalignment opening 12. The misalignment port 12 is staggered, so that the blocking block 11 can block and stabilize the positioning column 9 and the positioning cylinder 8, ensuring the stable insertion and positioning of the positioning column 9. When the external slag powder is added to the top of the screen 3 through the top feed hopper of the screening machine 1, the material distribution frame 4 is installed on the top of the screen 3 with a slope, and the material distribution columns 6 are set at intervals. As the slag powder is added to the top of the screen 3, the multiple material distribution columns 6 cooperate with the material distribution cylinder 7 to block and separate the slag powder on the top of the screen 3, so that the slag powder is distributed on the top of the screen as it moves, so that the screen 3 can fully screen the slag powder.

[0036] It should be noted that the screening machine 1, the base frame 2 and the screen 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
