Description

Technical Field

[0001] This application relates to the field of cement production technology, and more specifically, to a cement raw material silo feeding device. Background Technology

[0002] Cement raw meal is a material made by mixing limestone raw materials, clay raw materials, and a small amount of corrective raw materials in a certain proportion and grinding them to a certain fineness. Cement raw meal is the raw material for preparing cement clinker. During the preparation process, the raw meal silo storing cement raw meal needs to be opened and the material is fed into the preheater. Cement raw meal is prone to absorbing water and moisture, which can cause it to stick and clump together, resulting in blockage of the raw meal silo and poor material feeding. This is more serious during the rainy season. Currently, manual cleaning is usually used to deal with the blockage. Moreover, the current raw meal silos are not convenient for cleaning the inside of the silo, which is time-consuming and labor-intensive. Summary of the Invention

[0021] 3. The cement raw material silo unloading device provided by the present invention allows for the removal of the first cover plate via a cover replacement mechanism and the installation of the second cover plate on the top of the silo when the interior of the silo needs to be cleaned. Subsequently, a cleaning mechanism sprays water into the interior of the silo to clean it. At the same time, a drive mechanism drives a rotating rod to rotate, which in turn drives a crushing rod, spiral blades, a first scraper, and a second scraper to rotate, thereby improving cleaning efficiency and enhancing the cleaning effect. By setting up the cleaning mechanism, it is convenient to clean the interior of the silo, saving time and effort.

[0022] 4. The cement raw material silo feeding device provided by the present invention allows the raw material silo to work normally when the first cover plate is installed, and prevents splashed cement raw material from damaging the cleaning mechanism. When the second cover plate is installed, the raw material silo can be cleaned, and prevents water from splashing out from the feed hopper.

By setting up the crushing rod 14, the spiral blade 13, the first scraper 15 and the second scraper 16, the adhering and lumpy cement raw material can be broken up and the cement raw material adhering to the inner wall of the silo 1 can be scraped off, effectively preventing the raw material silo from being blocked and ensuring smooth and stable feeding.

[0050] When the interior of the chamber 1 needs to be cleaned, the first cover plate 2 is removed by the cover replacement mechanism 5, and the second cover plate 3 is installed on the top of the chamber 1. Then, water is sprayed into the interior of the chamber 1 by the cleaning mechanism 7 to clean the interior of the chamber 1. At the same time, the drive mechanism 4 drives the rotating rod 12 to rotate, and the rotating rod 12 drives the crushing rod 14, the spiral blade 13, the first scraper 15 and the second scraper 16 to rotate, which can improve the cleaning efficiency and improve the cleaning effect. By setting the cleaning mechanism 7, it is convenient to clean the interior of the chamber 1, saving time and effort.

[0067] Working Principle: In normal operation, the cement raw material silo feeding device provided in this application operates as follows: The second motor 51 is activated, driving the screw 53 to rotate. The screw 53 causes the first screw sleeve 54 and the second screw sleeve 55 to move left and right. The first screw sleeve 54 drives the first cylinder 56 to move, which in turn drives the first connecting block 58 to move. The first connecting block 58 then moves the first cover plate 2 left and right to the top of the silo body 1. Subsequently, the first cylinder 56 is activated, causing the first connecting block 58 to descend. The first connecting block 58 then causes the first cover plate 2 to descend, installing it on top of the silo body 1. Cement raw material can then be fed into the silo body 1 via the feed hopper 21 for storage. Simultaneously, the vacuum cleaner 61 is activated, using the suction pipe 62 to clean the feed hopper 21. Dust inside is collected and sent to dust collection box 63; cement raw material inside the silo 1 is fed through feeding pipe 11. The first motor 41 is turned on to drive the rotating shaft 42 to rotate. The rotating shaft 42 drives the first bevel gear 43 to rotate. The first bevel gear 43 drives the second bevel gear 44 to rotate. The second bevel gear 44 drives the rotating rod 12 to rotate. The rotating rod 12 drives the crushing rod 14 and the spiral blade 13 to rotate. The crushing rod 14 stirs and crushes the cement raw material. The spiral blade 13 conveys the cement raw material evenly. The cement raw material is fed through feeding pipe 11. The rotating rod 12 simultaneously drives the first scraper 15 and the second scraper 16 to rotate. The first scraper 15 and the second scraper 16 scrape off the cement raw material adhering to the inner wall of the silo 1.

[0068] When cleaning of the interior of chamber 1 is required, the first cylinder 56 is activated, causing the first connecting block 58 to rise. The first connecting block 58 then causes the first cover plate 2 to rise and be disassembled. Subsequently, the second motor 51 is activated, causing the screw 53 to rotate. The screw 53 causes the first threaded sleeve 54 and the second threaded sleeve 55 to move left and right. The second threaded sleeve 55 causes the second cylinder 57 to move. The first cylinder 56 causes the second connecting block 59 to move. The second connecting block 59 causes the second cover plate 3 to move left and right to above chamber 1. Then, the second cylinder 57 is activated. The second connecting block 59 is lowered, and the second connecting block 59 lowers the second cover plate 3, which is then installed on the top of the chamber 1. Then, the water pump 71 is turned on to pump water from the water tank 72 into the water outlet pipe 73 and spray it out from the nozzle 74, spraying water into the interior of the chamber 1 to clean the interior of the chamber 1. At the same time, the drive mechanism 4 drives the rotating rod 12 to rotate, which in turn drives the crushing rod 14, the spiral blade 13, the first scraper 15 and the second scraper 16 to rotate, which can improve the cleaning efficiency and enhance the cleaning effect.

[0069] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
