Description

Technical Field

[0001] The invention relates to the technical field of vertical rotary kilns, in particular to an energy-saving vertical rotary kiln. Background Art

[0002] Vertical rotary kilns are common heat treatment equipment in modern industry, widely used in industries such as cement, ceramics, metallurgy, and chemicals. Their primary function is to heat, sinter, or calcine materials at high temperatures, ensuring their quality and performance. Traditional vertical rotary kilns rely primarily on heat generated by burners to achieve high-temperature treatment within the kiln.

[0003] However, with the continuous expansion of industrial production scale, the energy efficiency of traditional rotary kilns is low, there is energy waste, and they cannot meet the needs of modern industry for energy conservation and consumption reduction. Due to the large temperature changes in the rotary kiln, it is difficult to achieve accurate temperature monitoring and adjustment, which not only affects the quality of the product, but also leads to further waste of energy. During the combustion process, the flue gas emitted by the rotary kiln often contains a large amount of harmful substances. If there are no effective flue gas treatment measures, it will cause pollution to the environment and even affect the health of workers. After a long period of operation, the rotary kiln is prone to accumulate dust, residues and scale inside, which not only affects the heat exchange effect of the kiln body, but may also cause equipment failure or reduce its service life.

The burner is set to heat the inside of the kiln body, and the operation panel is opened manually. The operation panel starts to drive the first vacuum pump to start, and the first vacuum pump starts to drive the gas input pipe and the inside of the kiln body, thereby driving the high-temperature flue gas generated by the combustion to flow upward from the bottom of the kiln. When the temperature inside the kiln body is too high, it can be cooled by the cooler, so that the device has a heating treatment and temperature monitoring structure, making the production process safer, more environmentally friendly and efficient, and meeting the dual needs of modern industry for energy saving and consumption reduction and environmental protection; by manually opening the operation panel, When the operation panel is started, the second motor is started, and the second motor drives the driving wheel, belt, driven wheel, connecting shaft, fixed sleeve, fixed rod, scraper and brush to rotate, so that they slide on the upper side of the inner wall of the kiln body, which can effectively remove material residue, ash and dirt, ensure the cleanliness of the inner wall of the kiln body, and thus extend the service life of the equipment; by manually opening the operation panel, the operation panel is started to drive the second vacuum pump, and the second vacuum pump is started to drive the connecting pipe and the vacuum pipe for extraction, and the vacuum pipe extracts the kiln body, and the flue gas enters the collection box from the vacuum pipe. The filter screen is set to filter the flue gas, and impurities fall to the upper side of the filter screen. The gas enters the second vacuum pump from the inside of the connecting pipe and is discharged. The plug rod is manually pulled out of the socket, and the movement of the plug rod drives the spring to stretch, and then the filter screen is manually pulled out of the socket slot, so that efficient flue gas extraction and treatment are achieved, ensuring the cleanliness and safety of the production environment. At the same time, the simple maintenance design not only reduces labor costs, but also optimizes operating efficiency.

When the temperature inside the kiln body is too high, it can be cooled by the cooler, realizing that the device has a heating treatment and temperature monitoring structure, making the production process safer, environmentally friendly and efficient, and meeting the dual needs of modern industry for energy saving and consumption reduction and environmental protection.

[0017] 2. The present invention manually opens the operation panel, and the operation panel starts to drive the second motor to start. The second motor starts to drive the driving wheel, belt, driven wheel, connecting shaft, fixed sleeve, fixed rod, scraper and brush to rotate, so that they slide on the upper side of the inner wall of the kiln, thereby effectively removing material residues, ash and scale, ensuring the cleanliness of the inner wall of the kiln, and thus extending the service life of the equipment.
