Abstract
Description
Technical Field
[0001] This utility model relates to the field of cement silo technology, and in particular to a dust prevention device for cement silos. Background Technology
[0002] A mud conveying silo, also known as a cement silo, is generally used in concrete mixing plants for storing bulk cement. It is suitable for storing various bulk building materials such as cement and fly ash. The silo is equipped with a material level system to display the position and quantity of the material, and a breaking device to remove compaction caused by prolonged material accumulation. When used in conjunction with a screw conveyor pump, the mud conveying silo can transport materials to various locations. This type of silo is easy to install, safe, and reliable, making it an ideal bulk storage tank for various mixing plants.
[0003] In existing cement silos, a large amount of dust is generated during the filling process, as cement falls into the silo. This dust easily disperses into the air, causing dust pollution to the surrounding environment and making the silos inconvenient to use. Therefore, we propose a cement silo dustproof device to solve the above-mentioned problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the generation of a large amount of dust during the actual use of cement when it falls into the cement silo, which easily disperses into the air and causes dust pollution to the surrounding environment, making it inconvenient to use. Therefore, a cement silo dust prevention device is proposed.

[0025] Example
[0026] Reference Figures 1-4 A dust control device for cement silos, comprising:
[0027] The system comprises a base 1, a support frame 2, a cement silo 3, a fixing frame 4, a filter plate 5, mounting buckles 6, and trapezoidal blocks 16. The support frame 2 is fixedly connected to the top of the base 1, the cement silo 3 is fixedly connected to the inner wall of the support frame 2, the fixing frame 4 is fixedly connected to the top of the cement silo 3, the filter plate 5 is movably connected to the top of the fixing frame 4, and there are two mounting buckles 6 and two trapezoidal blocks 16. The two mounting buckles 6 are symmetrically fixedly connected to the bottom of the filter plate 5, and the two trapezoidal blocks 16 are symmetrically slidably connected to the left and right sides of the fixing frame 4. The side of the two trapezoidal blocks 16 that is close to each other extends into the interior of the fixing frame 4, and the trapezoidal blocks 16 are adapted to the mounting buckles 6.
[0028] The locking mechanism is connected to the trapezoidal block 16 and is used to move the trapezoidal block 16 to fix the filter plate 5.
[0029] The above-mentioned mechanisms facilitate the support of the cement silo 3 by means of the support frame 2, the filter plate 5 facilitates the filtration and interception of floating dust to prevent the dust from scattering, and the locking mechanism facilitates the fixing of the filter plate 5.
[0030] As a preferred embodiment of this utility model, the locking mechanism includes: a control plate 7, two connecting frames 10, two pull rods 11, two sliders 12, and two moving frames 14;
[0031] The control panel 7 is slidably connected to the front side of the fixed frame 4. Two connecting brackets 10 are symmetrically fixedly connected to the rear side of the control panel 7. Two pull rods 11 are rotatably connected to the rear side of the corresponding connecting brackets 10. Two sliders 12 are rotatably connected to the rear side of the corresponding pull rods 11. Two moving brackets 14 are fixedly connected to the top of the corresponding sliders 12. The side of the two moving brackets 14 that is close to each other is fixedly connected to the side of the two trapezoidal blocks 16 that is far away from each other. Moving the control panel 7 will cause the two connecting brackets 10 to move down. Moving the connecting brackets 10 will pull the pull rods 11. Moving the pull rods 11 will pull the two moving brackets 14 to move to the side that is far away from each other. When the moving brackets 14 move, they will compress the return spring 15 and cause the trapezoidal blocks 16 to move laterally and disengage from the mounting buckle 6, thus unlocking the filter plate 5.
[0032] As a preferred embodiment of this utility model, a fixing frame 8 is fixedly connected to the front side of the fixing frame 4. The fixing frame 8 passes through the control plate 7, and the fixing frame 8 can conveniently limit the control plate 7 so that the control plate 7 can only move up and down.
[0033] As a preferred embodiment of this utility model, a limiting spring 9 is fixedly connected to the bottom of the control board 7. The bottom of the limiting spring 9 is fixedly connected to the top of the fixing frame 8. The elastic force of the limiting spring 9 is used to facilitate pushing the control board 7 to move upward and reset.
[0034] As a preferred embodiment of this utility model, the left and right sides of the fixed frame 4 are fixedly connected to the limiting frame 13. The inner wall of the limiting frame 13 is slidably connected to the outer wall of the slider 12, and the top of the limiting frame 13 is slidably connected to the bottom of the moving frame 14. The limiting frame 13 can conveniently limit the moving frame 14 and the slider 12, so that the moving frame 14 and the trapezoidal block 16 can only move laterally.
[0035] As a preferred embodiment of this utility model, a return spring 15 is fixedly connected to the side of each of the two limiting frames 13 that is far apart from each other. The side of each of the two return springs 15 that is close to each other is fixedly connected to the side of each of the two moving frames 14 that is far apart from each other. The elastic force of the return spring 15 makes it easy to push the moving frame 14 to reset so that the trapezoidal block 16 engages with the mounting buckle 6.
[0036] It should be noted that the specific type of cement silo 3 and filter plate 5 used should be selected by those skilled in the art, and the above-mentioned cement silo 3 and filter plate 5 are all existing technologies, which will not be elaborated in this solution.
[0037] The working principle of this utility model is as follows: In actual use, when cement needs to be stored, the base 1 is placed in a suitable position. An inlet pipe is located on the right side of the cement silo 3, and an outlet pipe is located at the bottom of the cement silo 3. Cement is added into the cement silo 3 through the inlet pipe. This causes a change in air pressure inside the cement silo 3, resulting in cement dust floating in the air. The filter plate 5 filters the dust, preventing it from scattering and achieving a dust-proof effect, thus avoiding pollution of the surrounding environment. During use, a cover plate or rain shelter can be installed on the top of the fixed frame 4 according to usage requirements to prevent rainwater from entering the cement silo 3. The appropriate option should be selected based on usage needs. When the filter plate 5 needs to be installed, the mounting buckle 6 is aligned with the trapezoidal block 16, and the filter plate 5 is pushed down. The mounting buckle 6 will then contact the inclined surface at the top of the trapezoidal block 16, thereby pushing the trapezoidal block 16 to move laterally. When the trapezoidal block 16 moves, it will cause the moving frame 14 to move laterally and compress the return spring 15. When the hollow part of the mounting buckle 6 moves to the position aligned with the trapezoidal block 16, the return spring 15 loses its restraint and pushes the moving frame 14 to move laterally, thereby causing the trapezoidal block 16 to move laterally and reset to engage with the mounting buckle 6, thus installing the filter plate 5. When it is necessary to remove the filter plate 5, press the control plate 7 directly. At this time, the control plate 7 moves down and compresses the limit spring 9. At the same time, the movement of the control plate 7 will cause the two connecting frames 10 to move down. The movement of the connecting frames 10 will pull the pull rod 11. The movement of the pull rod 11 will pull the two moving frames 14 to move to the side away from each other. When the moving frame 14 moves, it will compress the return spring 15 and cause the trapezoidal block 16 to move laterally and disengage from the mounting buckle 6. At this time, the filter plate 5 can be directly removed, which has good practicality and convenience.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
