Abstract
Description
Technical Field
[0001] This application relates to the field of drying technology, specifically a rotary kiln for drying. Background Technology
[0002] Rotary kilns for drying are widely used equipment in building materials, metallurgy, chemical industry and other fields. They are mainly used for drying loose materials and are key equipment in cement raw material production, calcination of building ceramsite, waste incineration and other fields.
[0003] The core function of a rotary kiln for drying is to achieve dehydration, drying, or calcination processes by ensuring full contact between the material and the high-temperature hot airflow.
[0004] For example, the patent with publication number CN209246651U discloses a rotary dryer. This patent uses a transmission mechanism to both transmit power and support rollers. Therefore, the rotary dryer does not need to be equipped with support rollers, making the structure simpler and reducing manufacturing costs.
[0005] During the actual drying process, the material itself may adhere to the inside of the kiln due to its properties, such as stickiness and humidity. The adhered material may fall off during the next drying cycle and mix into other products, thus affecting the quality of other products.
[0006] Therefore, it is necessary to provide a drying rotary kiln to solve the above problems.
[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0035] like Figures 1-4As shown, this application provides a drying rotary kiln, including a support 1 and a drying mechanism 2 disposed on the upper end of the support 1. The drying mechanism 2 is used to dry materials. The drying mechanism 2 includes a sealing plate 20 fixedly disposed on one side of the upper end of the support 1, and a fixing plate 40 fixedly disposed on the other side of the upper end of the support 1. A roller 21 is rotatably disposed between the sealing plate 20 and the fixing plate 40. The roller 21 is used to provide a good drying environment for the materials.
[0036] Meanwhile, a feed valve port 22 is fixedly opened at one end of the drum 21. The feed valve port 22 is connected to the inside of the drum 21 so that the material can be smoothly introduced into the inside of the drum 21. A discharge valve port 23 is opened at the other end of the drum 21. The discharge valve port 23 is used to discharge the dried material.
[0037] In order to dry the material inside the drum 21, a heating assembly 29 is provided on the sealing plate 20. The heating assembly 29 includes a mounting box 290 fixedly mounted on one side of the sealing plate 20, and multiple sets of heating wires 292 are fixedly mounted inside the mounting box 290. The heating wires 292 are used to provide heat energy for the drying operation. At the same time, a heat-conducting pipe 293 is fixedly mounted on the side of the mounting box 290 near the sealing plate 20. The heat-conducting pipe 293 is connected to the mounting box 290 and extends through the sealing plate 20 into the inside of the drum 21 so that the heat energy of the heating wires 292 can be introduced into the heat-conducting pipe 293.
[0038] Meanwhile, multiple sets of small holes 294 are opened on the outside of the heat pipe 293, so that the heat energy inside the heat pipe 293 can be introduced into the drum 21 through the small holes 294, thereby drying the material inside the drum 21. In order to allow the heat energy to enter the drum 21 smoothly, a fan 291 is fixedly installed on the other side of the mounting box 290. The fan 291 is used to blow the heat energy of the heating wire 292 into the heat pipe 293, so that the heat energy can be smoothly introduced into the drum 21.
[0039] In order to ensure that the material is dried evenly, multiple sets of mounting seats 24 are fixedly installed in the middle of the support 1. A rotating shaft 25 is rotatably installed between the mounting seats 24. A first motor 26 is fixedly installed on one side of one set of mounting seats 24. The output end of the first motor 26 is fixedly connected to one end of the rotating shaft 25, so that the first motor 26 can be started to drive the rotating shaft 25 to rotate between the mounting seats 24.
[0040] Meanwhile, a large gear 28 is fixedly installed at the middle position on the outer side of the drum 21, and a small gear 27 is fixedly installed on the rotating shaft 25. The small gear 27 meshes with the large gear 28, so that starting the first motor 26 can drive the small gear 27 to drive the large gear 28 to rotate, thereby driving the drum 21 to rotate between the two side sealing plates 20. When the material enters the drum 21, the first motor 26 can be started to drive the drum 21 to rotate, thereby driving the material to tumble inside the drum 21. At the same time, a guide vane 41 is installed inside the drum 21. The guide vane 41 is spirally distributed inside the drum 21, so the first motor 26 can drive the drum 21 to rotate repeatedly, thereby driving the material to dry repeatedly inside the drum 21. After drying, the material can also be guided to the discharge valve port 23 by driving the drum 21 to rotate and using the guide vane 41 for discharge processing.
[0041] like Figure 3 and Figure 5 As shown, in order to prevent material from adhering to the inner wall of the drum 21 after drying, a cleaning mechanism 3 is provided on the fixed plate 40 on the other side of the support 1. The cleaning mechanism 3 includes a fixed shell 30 fixedly installed on one side of the fixed plate 40. The fixed shell 30 is hollow, and a blower 31 is fixedly installed at one end of the fixed shell 30. The output end of the blower 31 is connected to the inside of the fixed shell 30 so that airflow can be introduced into the inside of the fixed shell 30 through the blower 31.
[0042] Meanwhile, a ventilation pipe 32 is rotatably provided at the other end of the fixed shell 30. The ventilation pipe 32 passes through the fixed plate 40 and extends into the inside of the roller 21. The ventilation pipe 32 is also connected to the inside of the fixed shell 30, so that airflow can be introduced into the ventilation pipe 32. At the same time, an air outlet 37 is provided on the outside of the ventilation pipe 32 so that the airflow inside the ventilation pipe 32 can be introduced into the inside of the roller 21 through the air outlet 37, thereby achieving the purpose of cleaning the material attached inside the roller 21.
[0043] The above description is merely a preferred embodiment of this application and is 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.
