Description

Technical Field

[0001] The utility model relates to the technical field of rotary kiln batching and screening, in particular to a rotary kiln batching device with a screening structure. Background Art

[0002] The rotary kiln batching device is a device used in the rotary kiln production line, which is used to accurately feed various raw materials into the rotary kiln for calcination in a certain proportion and sequence. It is an important part of the rotary kiln production line and can affect the production efficiency and product quality of the production line.

[0003] The Chinese patent with the authorization announcement number CN208595803U discloses a rotary kiln, which specifically includes a kiln body and an annular toothed disc fixed on the outer periphery of the middle part of the kiln body; the outer part of the annular toothed disc is meshed with a kiln body driving member; the kiln body is provided with multiple sets of guide members on both sides of the kiln body driving member; the kiln body includes a large-diameter feeding section and a small-diameter rotating section; a throat section is integrally formed between the feeding section and the rotating section; the inner diameter of the feeding section is 3600mm, and the inner diameter of the rotating section is 3300mm; the inner diameter of one end of the throat section is 3600mm, and the inner diameter of the other end is 3300mm; the throat section is smoothly reduced from one end to the other end. The rotary kiln of the utility model sets the kiln body at the feeding section and the rotating section, and controls the feeding section to evenly feed the rotating section through the throat section. At the same time, hot gas combined heating and separate heat control are adopted to ensure the quality of material processing.

[0004] However, the rotary kiln of the above patent does not screen the ingredients before processing. Since the common rotary kiln ingredients have different volumes, the ingredients in the rotary kiln are not screened, so that the larger volume of ingredients cannot be fully burned when entering the rotary kiln, and the interior of the ingredients cannot be burned properly, resulting in an increase in the amount of ingredients used and an increase in the production cost of the factory. Utility Model Content

[0005] The utility model aims to solve the problem that the batching volume in the rotary kiln is large and the combustion is not complete, and the batching cannot be well integrated with other batchings, and provides a rotary kiln batching device with a screening structure.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0009] The utility model is further configured as follows: the through-hole grooves provided on the surface of the second section protection plate enable the fixing rods at both ends of the rolling drum to extend to the outside of the second section protection plate to be fixedly connected with the hydraulic rod.

[0010] By adopting the above technical solution, one end of the fixing rod passes through the through slot provided on the surface of the second section protection plate and is fixedly connected with one end of the hydraulic rod.

[0011] The utility model is further configured as follows: the hydraulic rod is extended and retracted inside the hydraulic cylinder, so that the hydraulic rod drives the fixed rod to move up and down at the same time, so that the rolling drum can crush the ingredients on the surface of the rolling plate while maintaining its own balance.

[0012] By adopting the above technical solution, an empty slot is opened at the bottom of the first section of the protective plate, and the length of the empty slot opened at the bottom of the first section of the protective plate is the same as the length of the screen shaft arrangement and installation.

[0015] The utility model is further configured that the hammer head and the saw gear are staggeredly rotatably mounted on the surface of the connecting shaft, so that the hammer head and the saw gear can be quickly centrifugally rotated, thereby accelerating the rotation speed of the hammer head and the saw gear.

[0018] In summary, the beneficial technical effect of the utility model is as follows: by designing structures such as screening mechanisms, crushing mechanisms and rolling mechanisms, the screening mechanism first performs a preliminary screening of the ingredients, transports the larger ingredients to the surface of the bottom plate, and flows the smaller ingredients into the rotary kiln along the empty groove opened at the bottom of the first section of the protective plate for melting; the larger ingredients are hammered by the crushing mechanism to reduce the volume of the ingredients, and after being screened through the screening net, they are finally moved to the surface of the rolling plate and rolled by the rolling mechanism, so that most of the larger ingredients can reach the conditions for melting in the rotary kiln; the design of structures such as screening mechanisms, crushing mechanisms and rolling mechanisms decomposes and screens the volume of the ingredients, so that the ingredients in the rotary kiln are fully burned, reducing the phenomenon of insufficient combustion of the ingredients, while avoiding waste of ingredients and reducing the production cost of the factory.
