Description

Technical Field

[0001] This application relates to the technical field of powder collection devices, specifically a powder bag dust suppression device. Background Technology

[0002] Powder bagging refers to a packaging method where powdered materials are placed in packaging bags. When the high-purity nano-grade metal oxide collection device discharges, the material enters the bag through the discharge pipe. If the bag is placed directly at the pipe outlet, the air in the bag will cause poor discharge and easily lead to the metal oxide dust being scattered, resulting in metal oxide dust pollution.

[0003] Therefore, there is an urgent need for a dust suppression device for powder bagging to solve the problem of dust generation during powder bagging. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a dust suppression device for powder bagging, which has the advantage of reducing powder dust and solves the problem of dust easily generated during powder bagging.

[0005] To achieve the above objectives, this application provides the following technical solution: a dust suppression device for bagged powder, comprising a discharge pipe and a fixing ring 1, wherein two sets of the fixing ring 1 are fixedly connected to the outer surface of the discharge pipe by screws, and a clamping structure and an exhaust structure are provided on the outer side of the fixing ring 1;

[0006] The clamping structure includes a support frame, a hydraulic cylinder, a connecting rod, a connecting block, a pressure plate, a support plate, a pressure sheet, and two fixing rings. The support frame is welded to the outside of the first fixing ring. The hydraulic cylinder is installed in the middle of the inner side of the support frame. One end of the connecting rod is fixedly connected to the output end of the hydraulic cylinder, and the other end of the connecting rod is fixedly connected to the connecting block by bolts. The inner sides of the connecting block and the support plate are rotatably connected to the pressure plate by rods. The other end of the pressure plate is fixedly connected to the outer surface of the pressure sheet by screws. The inner side of the pressure sheet is in close contact with the outer surface of the discharge pipe. The end of the support plate away from the pressure plate is welded to the outer surface of the second fixing ring. The two sets of the second fixing rings are fixedly connected to the outer surface of the discharge pipe by screws.

[0007] The pressure plate drives the pressing sheet to press the packaging bag tightly against the outer surface of the discharge pipe, so that the high-purity nano-grade metal oxide powder will not drift to the outside. At the same time, the air in the packaging bag can be discharged from the air outlet on the outside of the connecting ring, so that the high-purity nano-grade metal oxide powder can be discharged smoothly and dust can be reduced.

[0008] Preferably, the first fixing ring and the pressure plate are semi-circular ring structures, and the two sets of the first fixing ring and the pressure plate are located symmetrically on the outer surface of the discharge pipe.

[0009] Preferably, the connecting block is a U-shaped block.

[0010] Preferably, the support plate has a square slot on its inner side.

[0011] Preferably, the exhaust structure includes a connecting ring, an air outlet, a support plate, and a filter screen. The connecting ring is fixedly connected to the outer surface of the discharge pipe by screws. The air outlet is installed on the outside of the connecting ring and communicates with the inside of the discharge pipe through the connecting ring. The support plate is fixedly connected to the inside of the discharge pipe at a position corresponding to the air outlet by screws. The filter screen is disposed on the inside of the support plate.

[0012] Preferably, the connecting ring is located between the pressure plate and the fixing ring.

[0013] In summary, the beneficial effects of this application are:

[0014] This powder bag dust suppression device has a packaging bag placed on the outside of the discharge pipe. By adjusting the angle of the pressure plate, when the pressure plate rotates inward, it drives the pressure plate to press the packaging bag tightly against the outer surface of the discharge pipe, preventing the high-purity nano-grade metal oxide powder from drifting to the outside. At the same time, the air in the packaging bag can be discharged from the air outlet on the outside of the connecting ring, ensuring smooth discharge of the high-purity nano-grade metal oxide powder and reducing dust.

Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Please see Figure 1-4A dust suppression device for powder bagging includes a discharge pipe 1 and two fixing rings 2. Two sets of fixing rings 2 are fixedly connected to the outer surface of the discharge pipe 1 by screws. The fixing rings 2 are fixed by screws so that they can be easily disassembled and assembled. High-purity nano-grade metal oxide powder can be discharged from the discharge pipe 1 and put into a packaging bag. The fixing rings 2 are provided with a clamping structure and an exhaust structure on the outside.

[0022] Specifically, the clamping structure includes a support frame 3, a hydraulic cylinder 4, a connecting rod 5, a connecting block 6, a pressure plate 7, a support plate 8, a pressure piece 9, and a second fixing ring 10. The support frame 3 is welded to the outside of the first fixing ring 2. The hydraulic cylinder 4 is installed in the middle of the inner side of the support frame 3. One end of the connecting rod 5 is fixedly connected to the output end of the hydraulic cylinder 4, and the other end of the connecting rod 5 is fixedly connected to the connecting block 6 by bolts. The inner sides of the connecting block 6 and the support plate 8 are rotatably connected to the pressure plate 7 by rods. The connecting block 6 is a U-shaped block. The other end of the pressure plate 7 is fixedly connected to the outer surface of the pressure piece 9 by screws. The inner side of the pressure piece 9 is tightly attached to the outer surface of the discharge pipe 1. The first fixing ring 2 and the pressure piece 9 are semi-circular ring structures. The two sets of first fixing rings 2 and pressure pieces 9 are located symmetrically on the outer surface of the discharge pipe 1. The end of the support plate 8 away from the pressure plate 7 is welded to the outer surface of the second fixing ring 10. A square slot is opened on the inner side of the support plate 8. The two sets of second fixing rings 10 are fixedly connected to the outer surface of the discharge pipe 1 by screws.

[0023] With the above technical solution, when the packaging bag is placed on the outside of the discharge pipe 1, the hydraulic cylinder 4 is activated. The hydraulic cylinder 4 drives the connecting block 6 to move through the connecting rod 5. When the connecting block 6 moves, it drives the two ends of the pressure plate 7 to rotate around the rods inside the support plate 8. When the pressure plate 7 drives the support plate 8 to rotate inward, it can press the packaging bag to the outer surface of the discharge pipe 1, so that the packaging bag can easily collect high-purity nano-grade metal oxide powder. The fixing ring 1 and fixing ring 2 are connected by screws, so that the clamping structure can be easily disassembled.

[0024] Specifically, the exhaust structure includes a connecting ring 11, an air outlet 12, a support plate 13, and a filter screen 14. The connecting ring 11 is fixedly connected to the outer surface of the discharge pipe 1 by screws. The air outlet 12 is installed on the outside of the connecting ring 11 and communicates with the inside of the discharge pipe 1 through the connecting ring 11. The connecting ring 11 is located between the pressing plate 9 and the fixing ring 10. The support plate 13 is fixedly connected to the inside of the discharge pipe 1 at the position corresponding to the air outlet 12 by screws. The filter screen 14 is arranged inside the support plate 13.

[0025] With the above technical solution, when the high-purity nano-grade metal oxide powder is discharged from the discharge pipe 1, the packaging bag is placed on the outside of the discharge pipe 1. When the high-purity nano-grade metal oxide powder falls into the packaging bag, the air in the packaging bag is discharged from the air outlet 12, making the discharge of the high-purity nano-grade metal oxide powder smoother and reducing dust flying. The filter screen 14 on the inner side of the support plate 13 filters the dust in the discharged air, so that the dust stays inside the discharge pipe 1 and does not fly around.

[0026] During use, the pressure plate 7 drives the pressure plate 9 to press the packaging bag tightly to the outer surface of the discharge pipe 1, so that the high-purity nano-grade metal oxide powder will not drift to the outside. At the same time, the air in the packaging bag can be discharged from the air outlet 12 on the outside of the connecting ring 11, so that the high-purity nano-grade metal oxide powder is discharged smoothly and dust is reduced.

[0027] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
