DETAILED DESCRIPTION

[0021] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0022] Example 1

[0023] like Figure 1 - Figure 3As shown, the utility model proposes a calcining rotary kiln, comprising: a kiln shell 1, a processing component 2, a stirring component 3, an electric telescopic rod 4, a bottom plate 5, a support column 6, a rotating tube 7 and a heat exhaust pipe 8; the processing component 2 is connected to the inside of the kiln shell 1; and the stirring component 3 is connected to the kiln shell 1; the stirring component 3 includes a bracket installed on the outside of the kiln shell 1, the bracket is connected to the stirring motor 301, the driving end of the stirring motor 301 is connected to the connecting rod 302, the connecting rod 302 extends to the inside of the processing component 2 and is peripherally connected to the sleeve a303 and the sleeve b; the sleeve a303 is connected to the stirring scraper 304 for stirring the material; the sleeve b is connected to the mounting rod 305, and the mounting rod 305 is connected to the cleaning scraper 306 for cleaning the material on the inner wall of the processing component 2. When the material adheres to the inner wall of the heating kiln body 201, the cleaning scraper 306 can scrape the adhered material off the inner wall of the heating kiln body 201 during the rotation process. Finally, this part of the material is discharged from the heating kiln body 201 through stirring, which is convenient for improving the working effect of the heating kiln body 201.

[0024] To further illustrate, the processing assembly 2 includes a heating kiln body 201 mounted within the kiln housing 1. The heating kiln body 201 is connected to a movable track 202, which is connected to a universal wheel a203. The universal wheel a203 is mounted below a block 204. Each block 204 is connected to a cover 205. Four blocks 204 are provided, two by two, in a group. One group is connected to the moving track 202 via a universal wheel a203, and the other side is connected to a guide track 206 via a universal wheel b. The universal wheels a203 and b are each connected to a motor. The motor is connected to a controller. The controller controls the motor drive to control the movement of the universal wheels a203 and b, facilitating the opening or closing of the cover 205 according to the needs of the calcining rotary kiln and facilitating the addition of materials into the heating kiln body 201 in conjunction with the feed pipe 101.

[0025] To further illustrate, the heating kiln body 201 is provided with an opening a opposite to the feed pipe 101, and the opening a is opened or closed by the cover 205; an opening b is provided at one end of the heating kiln body 201 and connected to the discharge pipe 102. When the material is added to the heating kiln body 201 through the feed pipe 101, the cover 205 moves to open the opening a and opposite to the discharge port of the feed pipe 101, and the material enters the heating kiln body 201 through the opening a for processing; when the heating kiln body 201 is in the working state, the cover 205 moves and resets to close the opening a, thereby preventing the material from leaking from the opening a into the interior of the kiln body shell 1; the opening b is connected to the discharge pipe 102, so that the processed material can be discharged from the discharge pipe 102, which is convenient for the use of the calcining rotary kiln. The outer side of the heating kiln body 201 is connected to the gear teeth and is located in the annular groove; the rotary motor is connected to the outside of the kiln body shell 1, and the output end of the rotary motor is located on the inside of the kiln body shell 1. Its output end is connected to the gear gear through a bevel gear and a gear transmission. By arranging a rotary motor on the outer wall of the kiln body shell 1, the heat is blocked by the asbestos net at the kiln body shell 1 to prevent the rotary motor from overheating and affecting its operation; the asbestos layer arranged on the surface of the heating kiln body 201 can insulate the kiln body shell 1 to prevent the user from accidentally touching the kiln body shell 1 and causing damage.

[0026] To further illustrate, a heat exhaust pipe 8 is connected to the bottom of the kiln shell 1. The output end of heat exhaust pipe 8 is connected to a mounting pipe 801, which in turn is connected to the input end of the fan. The input end of heat exhaust pipe 8 extends into the interior of the kiln shell 1 to dissipate heat. When the calcining rotary kiln is not in use, the fan is activated to dissipate heat from the kiln shell 1 through the mounting pipe 801 and heat exhaust pipe 8. This heat removal facilitates the kiln's secondary operation.

[0027] Example 2

[0028] like Figure 1 and Figure 2 As shown, the present invention proposes a calcining rotary kiln. Based on the above embodiment, this embodiment further describes in detail the specific components of the kiln shell 1, the bottom plate 5, the support column 6 and the rotating tube 7, as well as the matching method.

[0029] Further explanation: The kiln shell 1 is connected to a feed pipe 101 at the top and a discharge pipe 102 on one side. The discharge pipe 102 is connected to a discharge motor 103. The drive end of the discharge motor 103 is connected to a sleeve, and the outer side of the sleeve is connected to a conveying blade. A filter is movably connected to the inside of the feed pipe 101. By starting the discharge motor 103, the discharge motor 103 drives the conveying blade to stir and convey the material in the discharge pipe 102, preventing the material in the discharge pipe 102 from being clogged. The filter prevents large particles or impurities from entering the interior of the heating kiln 201. The filter is detachably connected to the feed pipe 101 via a pull plate and a cover plate, facilitating the replacement or maintenance of the filter, thereby improving the use of the components of the calcining rotary kiln.

[0030] To further illustrate, the interior of the kiln shell 1 is connected to a heating pipe 104 for heating the material inside. An exhaust pipe 105 is installed on the outer wall of the kiln shell 1, with the input end of the exhaust pipe 105 extending to the inner wall of the kiln shell 1. Multiple heating pipes 104 are installed inside the kiln shell 1 to heat the material inside. The exhaust pipe 105 is used to discharge the heated and expanded gas, preventing excessive pressure inside the kiln shell 1 and improving the practicality of the kiln shell 1.

[0031] To further illustrate, an electric telescopic rod 4 is connected to the bottom of the kiln shell 1. The bottom of the electric telescopic rod 4 is mounted on a base plate 5, which is connected to a support column 6. The support column 6 is connected to a rotating tube 7, and the rotating tube 7 is mounted on the kiln shell 1. The use of the electric telescopic rod 4 to support the kiln shell 1 facilitates adjustment of the height of the kiln shell 1 via the electric telescopic rod 4. Adjustment of the kiln shell 1 drives the internal heating kiln body 201, facilitating tilting the heated kiln body 201 and flipping the material inside. This also facilitates discharge of the material from the rotary kiln equipment, improving material processing efficiency. The support column 6 and rotating tube 7 facilitate assisting the electric telescopic rod 4 in adjusting the angle of the kiln shell 1, thereby improving the stability of the calcining rotary kiln and enhancing the material processing efficiency of the calcining rotary kiln.

[0032] The working principle of the present invention is as follows: first, the cover 205 is moved to open the opening a and connect it to the discharge end of the feed pipe 101, and then the material is added to the heating kiln body 201 through the feed pipe 101 and the opening a. After the material is processed, the cover 205 is moved to close the opening a; the heating tube 104 heats the internal material and starts the stirring motor 301. The stirring motor 301 rotates the connecting rod 302, and the connecting rod 302 simultaneously drives the sleeve a303 and the sleeve b. The sleeve a303 drives the stirring scraper 304 to rotate in the heating kiln body 201, so that it stirs the material in the heating kiln body 201. Then the sleeve b rotates and drives the mounting rod 305. The mounting rod 305 drives the cleaning scraper 306. The cleaning scraper 306 rotates on the inner wall of the heating kiln body 201. During the stirring process, part of the material is prevented from adhering to the inner wall of the heating kiln body 201, which facilitates the operation of the calcining rotary kiln.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
