Description

Technical Field

[0001] The utility model relates to the field of lime processing, in particular to a lime calcining device. Background Art

[0002] Lime is a compound containing calcium, primarily divided into quicklime and hydrated lime. Quicklime, whose main component is calcium oxide, is a widely used chemical raw material with significant industrial value, primarily used in steel production, building materials, environmental protection, and fertilizer production. For example, quicklime is a key component of concrete and mortar, enhancing the strength and durability of building materials. To produce quicklime, limestone (primarily composed of calcium carbonate) undergoes a high-temperature calcination process. During this process, the calcium carbonate in the limestone decomposes into calcium oxide and carbon dioxide. Calcination not only transforms the limestone into quicklime but also effectively removes moisture and other volatile impurities from the limestone, resulting in a purer quicklime. Calcined quicklime is more reactive than limestone, reacting more effectively with substances such as water and acids to produce calcium hydroxide and other compounds. This high reactivity gives quicklime unique advantages in a variety of chemical reactions and industrial applications. Therefore, the calcination process is an essential step in its production and application.

[0003] However, existing calcining devices usually leave some residues on the calcining furnace wall. These residues will reduce the thermal efficiency, affect the product quality of the lime and even affect the service life of the calcining furnace. Therefore, it is urgent to design a lime calcining device.

[0004] For example, the Chinese patent with authorization announcement CN215909649U discloses a calcining device for limestone production and processing, including a calcining tube and two rectangular plates. The two rectangular plates are hinged to each other, and cylinders are installed on both sides of the upper rectangular plate. Drive gears are installed at both ends of the cylinder. Pulleys and belts are installed on the sides of the drive gear. A motor is installed at the upper end of the upper rectangular plate, and the motor output shaft is connected to one of the pulleys.

[0005] Although the calcining device for limestone production and processing can calcine lime, some residues will be generated on the calcining furnace wall during calcination. These residues will reduce thermal efficiency, affect the product quality of the lime and even affect the service life of the calcining furnace.

[0006] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0031] With the help of the above technical scheme, the utility model can stir and calcine the lime raw material under the coordinated action of the cylinder 6, the heating furnace 7, the calcining furnace 8, the driving mechanism 9, the cover 11, the clamping mechanism 12, the stirring mechanism 14 and the electromagnetic valve 15, and effectively scrape off the residue on the inner wall of the calcining furnace 8, thereby improving the calcination efficiency of the lime, extending the service life of the calcining furnace 8, and facilitating the discharge of the material; under the coordinated action of the cover 11, the clamping mechanism 12 and the electromagnetic valve 15, the lime is in a closed space during the calcination process, thereby improving the calcination efficiency of the lime, and facilitating the disassembly and cleaning of the stirring mechanism 14; under the coordinated action of the driving mechanism 9 and the stirring mechanism 14, the calcining furnace 8 is effectively driven to rotate at a uniform speed on the heating furnace 7, ensuring uniform distribution of heat and achieving the best heating effect. At the same time, the residue on the inner wall of the calcining furnace 8 is effectively scraped off, thereby improving the calcination efficiency of the lime and extending the service life of the calcining furnace 8.

[0032] In addition, the lime calcining device of the present invention can not only calcine lime, but also adapt to calcine other mineral materials (such as magnesium ore, etc.) according to different parameters by changing the parameters of the heating furnace 7, the driving mechanism 9 and the stirring mechanism 14, thereby improving the calcination efficiency and product quality of other mineral materials during the calcination process.

[0033] In one embodiment, for the above-mentioned feed port 10 and discharge port 13, an electromagnetic valve 15 is provided on the outer side of the circumference of the feed port 10 and the discharge port 13, so that the opening and closing of the feed port 10 and the discharge port 13 can be controlled by the electromagnetic valve 15, so that the lime is in a closed space during the calcination process, effectively preventing the lime from spilling during the rotation of the calcining furnace 8.

[0034] It needs to be explained that the solenoid valve 15 is usually composed of several main components: an electromagnetic coil, a valve body, a valve core, a spring, a seal and a port; the electromagnetic coil is the core component of the solenoid valve, which generates a magnetic field when energized to attract or release the valve core; the electromagnetic coil is the power source for controlling the switch of the solenoid valve; the valve body is the outer shell of the solenoid valve, usually made of metal or plastic material, and contains a fluid channel and a valve seat inside; the valve core is the moving part inside the solenoid valve, responsible for opening or closing the fluid channel; the spring is used to maintain the valve core in the default position when not energized, usually the closed position. When the electromagnetic coil is energized, the valve core is attracted, overcomes the force of the spring, and opens the fluid channel; seals include O-rings, gaskets, etc., to ensure the seal between the valve body and the valve core to prevent fluid leakage; the port is used to connect pipes and control the inflow and outflow of fluids; the solenoid valve 15 is electrically connected to the control panel 3. The working principle and structure of the solenoid valve are existing technologies and will not be elaborated here.

[0035] In one embodiment, for the above-mentioned placement trough 2 and placement plate 5, a connecting column 16 cooperating with the cylinder 6 is provided on one side of the inner wall of the placement trough 2, and a connecting column 2 17 cooperating with the cylinder 6 is provided on one side of the placement plate 5. One side of the connecting column 16 is movably connected to the bottom end of the cylinder 6, and one side of the connecting column 2 17 is movably connected to the top end of the cylinder 6, so that the placement plate 5 can be driven to move by the cylinder 6, and the inclination of the placement plate 5 can be controlled to facilitate the pouring out of the calcined lime.

A cylinder 903 is sleeved inside the gear ring 2 902, and a plurality of support columns 904 that cooperate with the placement plate 5 are set at the bottom end of the cylinder 903, and a motor 905 is set at one end of one of the cylinders 903, thereby effectively driving the calcining furnace 8 to rotate at a uniform speed on the heating furnace 7, ensuring uniform distribution of heat, achieving the best heating effect, and greatly improving the calcining efficiency of lime.

[0037] It needs to be explained that insulation tiles are laid between the gear ring 901 and the calcining furnace 8 and are fixed between the calcining furnace 8 and the gear ring 901 by bolts. The insulation tiles are mainly composed of ceramic materials, composite materials, pore structures and coatings; common ceramic materials include aluminum silicate ceramics, alumina ceramics, etc. These materials have excellent high temperature resistance and thermal insulation capabilities; composite materials can improve the strength and toughness of the insulation tiles and reduce weight; the pore structure can effectively reduce heat conduction; the coating can further improve the heat resistance and oxidation resistance of the insulation tiles. This is an existing technology and will not be repeated here.

Under the action of the gear ring 2 902 and the cylinder 903 on both sides, the gear ring 1 901 rotates stably, and during the rotation of the gear ring 1 901, it drives the calcining furnace 8 to rotate, thereby achieving uniform heating of the calcining furnace 8.

When the handle 1203 is close to the mounting seat 1201, the vertical plate 1205 passes through the handle 1203. At this time, the limiting rod 1207 is passed through the limiting groove 1206, and the nut 1208 is tightened so that the nut 1208 is fitted with the vertical plate 1205, thereby achieving the closure of the cover body 11 and the calcining furnace 8.

[0042] The working principle of the stirring mechanism 14 is as follows: under the action of the control panel 3, the motor 2 1401 is controlled and started, and the output shaft of the motor 2 1401 drives the driving gear 1402 to rotate clockwise, and during the clockwise rotation of the driving gear 1402, the meshing driven gear 1403 is driven to rotate counterclockwise, and under the action of the fixed shaft 1404, the driven gear 1403 rotates stably, and during the counterclockwise rotation of the driven gear 1403, the bevel gear 1 1405 is driven to rotate counterclockwise, and during the rotation of the bevel gear 1405, the outer rotating plate 1409 is driven to rotate counterclockwise, and during the counterclockwise rotation of the rotating plate 1409, the connecting rod 1410 is driven to rotate counterclockwise, and during the counterclockwise rotation of the connecting rod 1410, the scraper 141 is driven. 1 rotates counterclockwise to scrape off the residue on the inner wall of the calcining furnace 8.
