[0002] In modern industrial production, calcination is a crucial step in many industries, such as chemical engineering, metallurgy, and building materials. Its purpose is to alter the physicochemical properties of materials through high-temperature treatment to meet the requirements of subsequent processing or product quality.

[0003] Existing calcination equipment uses a burner to completely combust natural gas (or diesel) in the combustion chamber, generating high temperatures. These temperatures are measured and displayed using temperature sensors, a controller, a display screen, an input module, and an electromagnetic regulating valve. The temperature within the combustion chamber can be adjusted and stabilized, and the heat is transferred to the rotating drum. This heat is then transferred to the material through the drum, achieving high-temperature calcination. The heated rotating drum drives the material in a rotational motion, constantly changing the heat exchange surfaces between materials, thus achieving uniform calcination. Simultaneously, it moves the material towards the discharge port. A gear transmission device drives the rotating drum to rotate, thus moving the material forward. The material movement speed is adjustable. The calcination time can be controlled by a frequency converter to control the drive motor.

[0024] 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.

[0025] 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.

[0026] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides an indirect infrared rotary drum calcination equipment system, including a base 1, a calcination mechanism 2, a gear drive mechanism 3, and a feeding mechanism 4. The calcination mechanism 2 is installed above the base 1, and the vibration-assisted feeding mechanism 4 is located on one side of the calcination mechanism 2.

[0027] The calcination mechanism 2 includes a mounting frame 201, a rotary cylinder 202, and a discharge hood 204, which can discharge the calcined material.

[0028] The gear drive mechanism 3 includes a rotary reduction motor 301 and a drive shaft 302. The rotary reduction motor 301 can rotate the drive shaft 302, thereby activating the vibration-assisted feeding mechanism 4.

[0029] The vibration-assisted feeding mechanism 4 includes a fixed frame 401, a linear guide rail 402, a guide rail slider 403, a groove 407, an extrusion wheel 406, a fixed rod 408, a return spring 409, a moving block 410, a wedge block 411, and a striking plate 412. One end of the drive shaft 302 is fixedly connected to a turntable 404, and one end of the turntable 404 is hinged to a connecting rod 405. The end of the connecting rod 405 away from the turntable 404 is hinged to the guide rail slider 403. When the drive shaft 302 rotates, the connecting rod 405 moves accordingly. The connecting rod 405 can reciprocate the guide rail slider 403 on the linear guide rail 402. The extrusion wheel 406 reciprocates with the guide rail slider 403, and the extrusion wheel 406 can reciprocate the wedge block 411 and the striking plate 412, thereby achieving… The striking plate 412 strikes and vibrates the discharge hood 204 to assist in material feeding. The fixed frame 401 is fixedly connected to one side of the discharge hood 204. The linear guide rail 402 is fixedly installed inside the fixed frame 401. The guide rail slider 403 is slidably connected to the outside of the linear guide rail 402. The extrusion wheel 406 is fixedly installed on one side of the guide rail slider 403. The groove 407 is opened inside the fixed frame 401. The fixed rod 408 is fixedly connected inside the groove 407. The return spring 409 is sleeved on the outer surface of the fixed rod 408. The moving block 410 is sleeved on the outer surface of the fixed rod 408. The wedge block 411 is fixedly connected to one side of the moving block 410. The striking plate 412 is fixedly connected to one side of the wedge block 411. A rubber block 413 is fixedly installed on one side of the striking plate 412.

[0030] The overall effect of Embodiment 1 is that by utilizing the rotation of the drive shaft 302 in the gear drive mechanism 3, the turntable 404 is driven to rotate, and then the guide rail slider 403 reciprocates on the linear guide rail 402 through the connecting rod 405. During this process, the extrusion wheel 406 moves synchronously, periodically extruding the wedge block 411 and pushing the striking plate 412 to strike and vibrate the discharge hood 204. This solves the problem that existing equipment is prone to blockage when the material is discharged through the discharge channel at a faster speed, which reduces the discharge efficiency. It improves the discharge efficiency. At the same time, the rubber block 413 installed on one side of the striking plate 412 can not only play a buffering role, reducing damage to the discharge hood 204 and extending its service life, but also reduce the noise generated by the striking and optimize the working environment.

[0031] Example 2: Figure 2 and Figure 3As shown, the mounting bracket 201 is fixedly connected to the top of the base 1, the rotary cylinder 202 is rotatably mounted on the inner surface of the mounting bracket 201, the discharge hood 204 is rotatably mounted on one end of the rotary cylinder 202 and fixedly connected to the top of the base 1, a temperature sensor is installed on the inner surface of the rotary cylinder 202, a feeding port 203 is provided at one end of the rotary cylinder 202, a mounting block 205 is fixedly sleeved on the outer surface of the rotary cylinder 202, an infrared electric heating chamber 206 is opened on the inner surface of the mounting block 205, and an infrared electric heating tube 207 is installed in the infrared electric heating chamber 206.

[0032] The overall effect of Embodiment 2 is that by installing a temperature sensor on the inner surface of the rotary cylinder 202, the calcination temperature of the material inside the cylinder can be monitored in real time and accurately. The temperature sensor is connected to an external control system, which facilitates timely adjustment of the calcination process by the operator. The feeding port 203 set at one end of the rotary cylinder 202 facilitates the input of materials. An infrared electric heating chamber 206 is opened in the mounting block 205 fixedly fitted on the outer surface of the rotary cylinder 202, and an infrared electric heating tube 207 is installed. The infrared electric heating tube emits infrared high-temperature radiation, which is conducted to the rotary cylinder 202 and then conducted to the product for calcination. The calcination process does not require air, which is more energy-saving and environmentally friendly than traditional combustion heating. The heat radiation is uniform during the heating process, which can effectively ensure the consistency of the calcination quality of the material and help improve product quality.

[0033] Example 3: As Figure 1 and Figure 2 As shown, a rotary geared motor 301 is fixedly installed on the top of the base 1, and a drive shaft 302 is fixedly connected to the output end of the rotary geared motor 301. A drive gear 303 is fixedly sleeved on the outer surface of the drive shaft 302, and a driven gear 304 is fixedly sleeved on the outer surface of the rotary cylinder 202. The drive gear 303 and the driven gear 304 are meshed and connected. A support mechanism 5 is installed above the base 1. The support mechanism 5 includes a bracket 501, which is fixedly connected to the top of the base 1. A support roller 502 is rotatably connected to the inner side of the bracket 501. A control box 6 is fixedly installed on the top of the base 1. A transformer 7 is installed inside the control box 6. A temperature display instrument 8 is installed on one side of the control box 6, and a frequency converter 9 is installed on the other side of the control box 6.

[0034] The overall effect of Embodiment 3 is that by starting the rotary reduction motor 301, the rotary cylinder 202 rotates, ensuring that the material rotates within the cylinder, completing the process of uniform calcination and the movement of the calcined material towards the discharge hood 204. The bracket 501 in the support mechanism 5 is fixed to the top of the base 1, and the inner rotating support roller 502 provides good support for the rotary cylinder 202, ensuring the stability of the rotary cylinder 202 during rotation and extending the service life of the equipment. The control box 6 installed on the top of the base 1 contains a transformer 7, a temperature display instrument 8 installed on one side, and a frequency converter 9 installed on the other side, realizing effective control and regulation of the equipment's electrical system. The temperature display instrument 8 is electrically connected to the temperature sensor, allowing the temperature display instrument 8 to provide a direct view of the temperature inside the cylinder. At the same time, the temperature sensor transmits the collected temperature data to the external control system. Based on the received temperature data and the temperature value preset by the operator, the external control system issues a command to the transformer 7. The transformer 7 then adjusts the voltage supplied to the infrared electric heating tube 207, thereby controlling the heating power of the infrared electric heating tube 207 and achieving precise control of the temperature inside the rotary cylinder 202. The frequency converter 9 precisely controls the rotary gear motor 301, thereby flexibly adjusting the material movement speed and calcination time, facilitating precise control of the calcination quality of the product.

[0035] Working principle: In operation, the rotational speed of the rotary geared motor 301 is set via the frequency converter 9, thereby determining the rotational speed of the rotary drum 202, and thus controlling the material movement speed and calcination time within the drum. Then, the rotary geared motor 301 is started, and its output shaft drives the drive shaft 302 to rotate. The drive gear 303, fixedly sleeved on the outer surface of the drive shaft 302, rotates accordingly. Since the drive gear 303 meshes with the driven gear 304 fixedly sleeved on the outer surface of the rotary drum 202, the rotation of the drive gear 303 drives the driven gear 304, causing the rotary drum 202 to begin rotating. The material begins to tumble inside the drum and moves towards the discharge hood 204. The infrared electric heating tube 207 starts working, heating the rotating drum 202. A temperature sensor monitors the temperature inside the rotating drum 202 in real time and displays it on the temperature display instrument 8. Simultaneously, the temperature sensor transmits the collected temperature data to the external control system. Based on the received temperature data and the operator's preset temperature value, the external control system sends a command to the transformer 7. The transformer 7 then adjusts the voltage supplied to the infrared electric heating tube 207, thereby controlling the infrared electric heating tube. The heating power of 207 allows for precise temperature control within the rotary drum 202. Simultaneously, the rotation of the drive shaft 302 causes the turntable 404 to rotate synchronously. A connecting rod 405, hinged at one end, oscillates in a circular motion. The end of the connecting rod 405 away from the turntable 404 is hinged to the guide rail slider 403. Driven by the connecting rod 405, the guide rail slider 403 reciprocates linearly on the linear guide rail 402 fixed inside the fixed frame 401. The extrusion wheel 406, fixedly mounted on one side of the guide rail slider 403, reciprocates synchronously with the guide rail slider 403. When the extrusion wheel 406 moves to the position of the guide rail slider 403... When the wedge 411 contacts, it generates a squeezing force on the wedge 411, pushing the wedge 411 and the movable block 410 fixedly connected to it to move along the fixed rod 408, compressing the return spring 409. At this time, the striking plate 412 fixedly connected to the other side of the wedge 411 also moves. When the squeezing wheel 406 leaves the wedge 411, the return spring 409 returns to its original deformation, driving the movable block 410, the wedge 411 and the striking plate 412 to reset. This cycle continues, and the striking plate 412 periodically strikes and vibrates the discharge hood 204 to prevent material from blocking the discharge channel and ensure smooth material discharge.

[0036] 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.
