Description

Technical Field

[0001] This utility model relates to the field of clinker silo dust removal technology, specifically a dust removal device for clinker silos. Background Technology

[0002] Clinker is sintered granular material formed after raw materials are calcined at high temperatures. It is an important semi-finished product in cement production, and clinker silos are places specifically used to temporarily store this clinker. If the dust generated in the clinker silos during cement production is not controlled, it will be directly emitted into the atmosphere, causing air pollution. Moreover, the dust in the clinker silos is pervasive, and workers working in this environment for a long time are prone to inhaling large amounts of dust, which can lead to respiratory diseases, pneumoconiosis, and other occupational diseases. The traditional dust removal method is to install an exhaust port on the clinker silo, connect one end of the conveying pipe to the exhaust port, and connect the other end of the conveying pipe to external dust removal equipment. Although this method can achieve a certain dust removal effect, the dust in the clinker silo is concentrated at the exhaust port and transported outward, which is not conducive to the discharge of dust in different areas of the clinker silo, and the dust collection efficiency needs to be improved.

Multiple branch pipes 42 are fixedly connected to the outer periphery of the pipe 411, and one end of each branch pipe 42 is fixedly connected to an annular pipe 43. A mounting post 431 is fixedly connected between the annular pipe 43 and the chamber 1. Multiple suction ports 44 are fixedly connected to the bottom of both the branch pipes 42 and the bottom of the annular pipe 43. A first adjusting block 45 and a second adjusting block 46 are installed inside the chamber 1. A guide rod 461 runs through the interior of segment 46. A fastening block 462 is fixedly connected to the bottom end of the guide rod 461. An installation ring 47 is fixedly connected between the first adjusting block 45 and the second adjusting block 46. Multiple unblocking rods 471 are fixedly connected to the top of the bracket 412 and the top of the installation ring 47. A servo motor 48 is fixedly connected to the top of the chamber 1. The drive end of the servo motor 48 passes through the top of the chamber 1 and is fixedly connected to a threaded rod 49. The bottom end of the threaded rod 49 is rotatably connected to a fixing block 491 via a bearing. One end of the bracket 412 is fixedly connected to the installation ring 47. The annular tube 43... The outer diameter is smaller than the outer diameter of the mounting ring 47. The center point of the unblocking rod 471 and the center point of the suction port 44 are on the same vertical line. The outer diameter of the unblocking rod 471 and the inner diameter of the suction port 44 are matched. The number of unblocking rods 471 and suction ports 44 are the same. The fixing block 491 is fixed to the inner wall of the chamber 1. The first adjusting block 45 is threaded onto the outside of the threaded rod 49. The top end of the guide rod 461 is fixed to the inside of the chamber 1. The fastening block 462 is fixed to the inner wall of the chamber 1.

The air intake mechanism 4 improves the traditional air intake method by adopting a distributed air intake layout, which increases the air intake range and facilitates the discharge of dust in different ranges, which is conducive to improving the dust collection efficiency. At the same time, the installation ring 47 and the unblocking rod 471 that can move up and down are used to facilitate the unblocking of dust in the suction port 44, preventing the suction port 44 from becoming blocked and affecting the normal dust removal in the chamber 1. The cleaning work can be completed without the need for manual climbing to a high place, which improves the cleaning efficiency.

[0019] Among them, the model of servo motor 48 is ACSM110-G04030LZ.

[0020] Working principle: When using this device, if there is a lot of dust in the chamber 1, turn on the exhaust fan 32. After the exhaust fan 32 is powered on, it can draw the dust in the chamber 1 into the branch pipe 42 and the annular pipe 43 through multiple suction ports 44, and then transport the dust to the dust collection box 3 through the pipe 411 and the conveying pipe 2. The dust is blocked when it passes through the filter cloth 33 and finally stays below the filter cloth 33. The clean air is discharged through the exhaust port of the exhaust fan 32. By improving the traditional air intake method, a distributed air intake layout is adopted, which increases the air intake range and facilitates the discharge of dust in different ranges, which helps to improve the dust collection efficiency. When the suction port 44 is open, the dust is drawn into the dust collection box 3. 4. When a blockage occurs, the servo motor 48 is activated. The forward and reverse rotation of the servo motor 48 drives the threaded rod 49 to rotate in both directions. The forward and reverse rotation of the threaded rod 49 drives the first adjusting block 45, the second adjusting block 46, the mounting ring 47, the bracket 412, and multiple sets of unblocking rods 471 to move up and down. The up and down movement of the multiple sets of unblocking rods 471 allows them to slide up and down within the suction port 44, thus facilitating the unblocking of dust in the suction port 44 and preventing the suction port 44 from becoming blocked, which would affect the normal dust removal in the chamber 1. The cleaning work can be completed without manual climbing to a high place, improving cleaning efficiency.
