Description

Technical Field

[0001] This utility model relates to the field of rotary kiln technology, and in particular to a rotary kiln with a uniformly heated atmosphere. Background Technology

[0002] Rotary furnaces are important thermal equipment in the energy and chemical industry, primarily used for the uniform calcination and drying of powder and granular materials, particularly suitable for reaction experiments in the activated carbon and coking coal industries. Atmosphere rotary furnaces are industrial equipment used to heat materials under a specific atmosphere. They combine the dynamic heating method of rotary furnaces (the furnace rotates to tumble the material) with controlled atmosphere technology, enabling precise control of parameters such as gas composition, pressure, and temperature within the furnace during heating to meet the heat treatment requirements of different materials.

[0003] In the prior art, such as the Chinese patent CN221198032U "An Atmosphere-Protected Rotary Furnace", an atmosphere furnace is included. A sealing door structure is installed on the side wall of the atmosphere furnace. Several heating structures are installed inside the atmosphere furnace. A support structure is installed on the lower wall of the atmosphere furnace. A rotating structure is installed inside the atmosphere furnace. An air pump structure is installed on the lower wall of the support structure. Mounting holes are provided on the lower wall of the atmosphere furnace. The sealing door structure includes: a furnace rotating seat, a door rotating seat, two door connecting rods, a furnace door, and a sealing plate. This utility model improves upon common atmosphere furnaces by installing a structure inside the atmosphere furnace that allows the workpiece to rotate. This allows rotating parts to slowly rotate inside the atmosphere furnace around their axis, thus ensuring uniform heat treatment and guaranteeing the quality of the heat treatment.

[0004] Existing rotary kilns are not convenient for unloading processed materials during use, which can easily lead to increased unloading time, reduced unloading efficiency, and consequently, reduced work efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that it is inconvenient to unload the processed materials, which easily leads to blockage of the unloading port, resulting in reduced unloading efficiency and reduced work efficiency. Therefore, this invention proposes a rotary furnace with a uniform heating atmosphere.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rotary furnace for uniform heating, comprising an atmosphere rotary furnace assembly, a shaking component at the bottom of the atmosphere rotary furnace assembly, a stirring and heating component inside the atmosphere rotary furnace assembly, the atmosphere rotary furnace assembly including a heat insulation cover and a rotary furnace, a heating tube wound between the rotary furnace and the heat insulation cover, both ends of the heating tube being connected to external heaters, the shaking component including a base plate, hydraulic telescopic columns symmetrically installed between the heat insulation cover and the base plate, both ends of the hydraulic telescopic columns being connected to a first rotating seat, a second rotating seat installed at the bottom of the heat insulation cover, a support column connected to the bottom of the second rotating seat, and the bottom of the support column being connected to the top of the base plate.

[0007] Preferably, the stirring and heating assembly includes a drive shaft, with multiple stirring rollers distributed on the outer side of the drive shaft. A scraper is installed at one end of each stirring roller, and an internal heater is installed on the side of each stirring roller. A heating wire is connected to the side of the internal heater and is wound around the outer side of the stirring roller.

[0008] Preferably, a stirring motor is installed at one end of the drive shaft, the drive shaft is installed inside the rotary kiln, and the scraper is connected to the inner wall of the rotary kiln.

[0009] Preferably, a furnace cover is installed at one end of the rotary kiln, and a sealing ring is installed on the inner side of the furnace cover.

[0010] Preferably, the heat insulation cover has multiple air inlet pipes installed on its side and multiple exhaust pipes installed on its top.

[0011] Preferably, a feeding pipe is installed at the bottom of the rotary kiln, and a valve is provided in the middle of the feeding pipe.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by controlling the simultaneous extension and retraction of two hydraulic telescopic columns, when the hydraulic telescopic columns extend, they rotate in conjunction with the first rotating seat, causing one end of the insulation cover to tilt upwards, thereby causing the feeding pipe to face downwards. The tilted end allows the material to flow naturally downwards in the rotary kiln, thus allowing the material to be discharged through the feeding pipe. This effectively avoids the accumulation and residue of material in the rotary kiln, shortens the feeding time, and improves the feeding efficiency. By controlling the extension and retraction of the hydraulic telescopic columns, it is beneficial to drive the insulation cover and the rotary kiln to shake, which helps the material to continuously change position in the rotary kiln, allowing the material to come into more comprehensive contact with the heat source. This avoids uneven heating caused by material accumulation or stillness, thereby improving the uniformity of material heating.

[0014] 2. In this utility model, when the stirring roller stirs the internal material, it works in conjunction with the internal heater, so that the heating wire releases heat evenly. The heating wire works in conjunction with the heating tube to heat the material, which helps to improve the heating speed of the material and thus improve the heating efficiency. At the same time, the heating wire continuously contacts the material at different positions as the stirring roller moves, directly transferring heat to the material, which helps to improve the uniformity of heating the material.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example

[0022] like Figures 1-4As shown, this utility model provides a technical solution: a rotary furnace with uniform heating atmosphere, including an atmosphere rotary furnace assembly 1, a shaking assembly 2 disposed at the bottom of the atmosphere rotary furnace assembly 1, a stirring and heating assembly 3 disposed inside the atmosphere rotary furnace assembly 1, the atmosphere rotary furnace assembly 1 including a heat insulation cover 101 and a rotary furnace 102, a heating tube 106 wound between the rotary furnace 102 and the heat insulation cover 101, the two ends of the heating tube 106 being connected to external heaters 105, the shaking assembly 2 including a base plate 204, the heat insulation cover 101 and the base plate Hydraulic telescopic columns 201 are symmetrically installed between 204. Both ends of the hydraulic telescopic columns 201 are connected to first rotating seats 202. A second rotating seat 205 is installed at the bottom of the heat insulation cover 101. A support column 203 is connected to the bottom of the second rotating seat 205. The bottom of the support column 203 is connected to the top of the base plate 204. A furnace cover 108 is installed at one end of the rotary kiln 102. A sealing ring 109 is installed on the inner side of the furnace cover 108. A feeding pipe 307 is installed at the bottom of the rotary kiln 102. A valve is provided in the middle of the feeding pipe 307.

[0023] In this embodiment, heating is achieved by controlling the external heater 105, which allows the heating tube 106 to release heat evenly, thus facilitating the heating of the rotary kiln 102. Simultaneous extension and retraction of the two hydraulic telescopic columns 201 are controlled. When the hydraulic telescopic columns 201 extend, they rotate in conjunction with the first rotating seat 202, causing one end of the insulation cover 101 to tilt upwards. This causes the feed pipe 307 to point downwards, and the tilted end allows the material to flow naturally downwards within the rotary kiln 102, thus allowing the material to be discharged through the feed pipe 307, effectively preventing material from being trapped in the kiln. The accumulation and residue in the converter 102 shortens the feeding time and improves the feeding efficiency of materials. By controlling the extension and retraction of the hydraulic telescopic column 201, it is beneficial to drive the insulation cover 101 and the rotary kiln 102 to shake, which helps the material to continuously change its position in the rotary kiln 102, so that the material can come into more comprehensive contact with the heat source, avoiding uneven heating caused by the static material, thereby improving the uniformity of material heating. The support column 203 helps to provide support for the insulation cover 101 and ensures the stability of the insulation cover 101. Example

[0024] like Figures 1-4As shown, the stirring and heating assembly 3 includes a drive shaft 302, with multiple stirring rollers 303 distributed on the outer side of the drive shaft 302. A scraper 304 is installed at one end of the stirring roller 303, and an internal heater 305 is installed on the side of the stirring roller 303. A heating wire 306 is connected to the side of the internal heater 305 and is wound around the outer side of the stirring roller 303. A stirring motor 301 is installed at one end of the drive shaft 302. The drive shaft 302 is installed inside the rotary kiln 102. The scraper 304 is connected to the inner wall of the rotary kiln 102. Multiple air inlet pipes 107 are installed on the side of the heat insulation cover 101, and multiple exhaust pipes 104 are installed on the top of the heat insulation cover 101.

[0025] In this embodiment, the atmospheric gas enters the rotary kiln 102 through the inlet pipe 107, and the exhaust pipe 104 facilitates the discharge of gas. The furnace cover 108 is threadedly connected to one end of the rotary kiln 102. The sealing ring 109 helps to provide a sealing effect, preventing dust and impurities from entering the rotary kiln 102. During processing, the stirring motor 301 electrically drives the transmission shaft 302 to rotate, which in turn drives the stirring roller 303 and scraper 304 to rotate. This facilitates the stirring of the material inside the rotary kiln 102, ensuring uniform heating of the material and allowing the material to make more full contact with the heat source. 304 is beneficial for scraping off the material adhering to the inside of the rotary kiln 102, reducing the amount of material residue on the rotary kiln 102. When the stirring roller 303 stirs the internal material, it works in conjunction with the internal heater 305, so that the heating wire 306 releases heat evenly. The heating wire 306 works in conjunction with the heating tube 106 to heat the material, which helps to improve the heating speed of the material and thus improve the heating efficiency. At the same time, the heating wire 306 continuously contacts the material at different positions as the stirring roller 303 moves, directly transferring heat to the material, which helps to improve the uniformity of heating the material.

[0026] The working principle of this embodiment is as follows: In use, the material is first placed inside the rotary kiln 102. The furnace cover 108 is threaded onto one end of the rotary kiln 102. The sealing ring 109 provides a sealing effect. Then, the external heater 105 is controlled to heat the material, causing the heating tube 106 to release heat evenly, thus facilitating the heating of the rotary kiln 102. Simultaneously, the stirring motor 301 electrically drives the transmission shaft 302 to rotate, thereby driving the stirring roller 303 and scraper 304 to rotate, which facilitates the stirring of the material inside the rotary kiln 102, ensuring uniform heating. The scraper 304 helps to scrape off any material adhering to the inside of the rotary kiln 102. When the stirring roller 303 stirs the material inside, it works in conjunction with the internal heater 305, ensuring that the heating wire 306 heats the material evenly. The heating wire 306 continuously contacts the material at different positions as the stirring roller 303 moves, directly transferring heat to the material. Then, the hydraulic telescopic column 201 is controlled to extend and retract, which helps to make the heat insulation cover 101 and the rotary kiln 102 shake, allowing the material to continuously change position within the rotary kiln 102 and enabling the material to come into more comprehensive contact with the heat source. Atmospheric gas enters the rotary kiln 102 through the air inlet pipe 107 and is conveniently discharged through the exhaust pipe 104. Finally, the hydraulic telescopic column 201 is controlled to extend, cooperating with the first rotating seat 202 to rotate, causing one end of the heat insulation cover 101 to tilt upwards, thereby causing the feed pipe 307 to face downwards. The tilted end allows the material to flow naturally downwards within the rotary kiln 102, and then the material is discharged through the feed pipe 307.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
