Description

Technical Field

[0001] The utility model relates to the technical field of cement processing, in particular to a low-alkali and high-strength cement calcining device. Background Art

[0002] For example, the patent publication number CN218314364U provides a high-strength sulphoaluminate cement raw material calcining device, which can observe the inside of the mixing drum while people knock and vibrate the mixing drum, making it convenient for people to clean the cement stuck inside the drum. A high-strength sulphoaluminate cement raw material calcining device includes a base plate, a support frame and a drum, etc. The bottom of the base plate is connected to a left-right symmetrical support frame, and the drum is rotatably connected between the support frames. By stepping on the front side of the squeezing hammer, the hammer rotates along the fixed axis, and then the volute spring enables the hammer to continuously move repeatedly, continuously knocking the drum, so that the cement remaining in the drum falls off, achieving the effect of making it convenient for people to clean the cement stuck inside the drum.

[0003] However, during the use of the above equipment, due to the setting of its internal stepping and extrusion hammer, the temperature of the calcining device is high, and the mixing barrel is hit by stepping on it, which not only increases the labor intensity of the workers, but also easily burns the workers. Therefore, in response to this situation, we propose a more convenient and practical calcining device that meets the use needs. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] In the process of cement processing, calcining equipment is needed. The calcining equipment provided by the utility model is specially used for cement calcining operations in the process of cement processing. In the process of using this equipment for calcining operations, it should be noted that the temperature in the furnace should be gradually increased according to the set temperature and time requirements. At the same time, the temperature changes in the furnace should be monitored to ensure that the speed and amplitude of the temperature increase are controlled within the appropriate range. A suitable proportion of raw materials should be added to the cement furnace, and the addition and discharge of raw materials should be controlled through the feed and discharge ports in the furnace. The air intake and oxygen content in the furnace during the calcination process should be controlled to maintain an appropriate oxygen supply. The waste gas, waste residue, etc. generated during the calcination process should be treated and discharged in accordance with regulations to reduce pollution to the environment.

[0020] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a low-alkali and high-strength cement calcining device, comprising a base 1, a calcining mechanism 2 is arranged on the top of the base 1, the calcining mechanism 2 comprises a support frame 201, the support frame 201 is connected to the base 1, the bottom of the support frame 201 is rotatably connected to a rotating drum 202, and knocking mechanisms 3 are symmetrically arranged on both sides of the top of the base 1, the knocking mechanism 3 comprises a support seat 301, a knocking assembly is rotatably connected to one side of the top of the support seat 301, and is used to knock the rotating drum 202, and a gear disk 302 is rotatably connected to one side of the middle part of the support seat 301.

[0021] like Figure 2As shown, a spiral plate 203 is fixedly connected to the inner wall of the rotating drum 202, a gear ring 204 is fixedly connected to the outer wall of one end of the rotating drum 202, a driving gear 205 is provided on one side of the gear ring 204, the driving gear 205 is rotatably connected to the support frame 201, a reduction motor 206 is installed on one side of the support frame 201, the output end of the reduction motor 206 is connected to the driving gear 205, a heater 207 is provided at the bottom of the rotating drum 202, the heater 207 is electrically connected to the base 1, and the output end of the heater 207 is in contact with the outer wall of the rotating drum 202.

[0022] It should be noted that during use, the cement is first placed in the drum 202 on the support frame 201, and then the reduction motor 206 drives the drive gear 205 to rotate, and drives the gear ring 204 and the drum 202. In this process, the heater 207 heats the drum 202 and prevents cement blockage under the action of the spiral plate 203. Due to the rotation of the drum 202 and the pushing action of the spiral plate 203, the calcining mechanism 2 can evenly roll forward in the kiln and be heated evenly, which not only ensures the quality stability of cement calcination, but also reduces the rate of raw burning and overburning, and improves the activity and quality of the product.

[0023] like Figure 3 As shown, a servo motor 303 is installed on one side of the support base 301, and the output end of the servo motor 303 is connected to the gear disk 302. A through hole is opened on one side of the top of the support base 301, and a connecting shaft 304 is rotatably connected in the through hole. A connecting block 305 is fixedly connected to the outer wall of the connecting shaft 304, and one end of the connecting shaft 304 is fixedly connected to a toggle plate 306, which is adapted to the teeth of the gear disk 302.

One end of the spring 310 is slidably connected to a fixed rod 311, and the fixed rod 311 is rotatably connected to the connecting rod 307.

[0024] It should be noted that during use, when cement is calcined in the calcining mechanism 2, the servo motor 303 on the support seat 301 drives the gear disc 302 to rotate, and the rotation of the gear disc 302 drives the connecting shaft 304 and the connecting block 305 to rotate through the toggle plate 306. While the connecting block 305 rotates, it drives the connecting rod 307 and the hammer head 308 to knock on the rotating drum 202. In this process, the spring 310 increases the knocking force under the action of the connecting sleeve 309 and the fixing rod 311. The knocking mechanism 3 can effectively prevent the cement raw materials from sticking to the inner wall of the container during the calcination process.

[0025] Working principle: During use, cement is first placed in the drum 202 on the support frame 201, and then the reduction motor 206 drives the driving gear 205 to rotate, and drives the gear ring 204 and the drum 202. In this process, the heater 207 heats the drum 202 and prevents cement clogging under the action of the spiral plate 203. When the cement is calcined in the calcining mechanism 2, the servo motor 303 on the support seat 301 drives the gear disc 302 to rotate. The rotation of the gear disc 302 drives the connecting shaft 304 and the connecting block 305 to rotate through the toggle plate 306. While the connecting block 305 rotates, it drives the connecting rod 307 and the hammer head 308 to knock the drum 202. In this process, the spring 310 increases the knocking force under the action of the connecting sleeve 309 and the fixed rod 311. The device realizes automated operation, reduces the need for manual intervention, reduces labor intensity, and improves the stability and controllability of the production process, while avoiding scalding workers.
