Description

Technical Field

[0001] The present invention relates to the technical field of roasting furnaces, and particularly to a roasting furnace device for quartz stone production. Background Art

[0002] A roasting furnace is an industrial device used for heating and processing various materials, and is widely applied in fields such as metallurgy, chemical industry, building materials, and environmental protection, including rotary roasting furnaces.

[0003] The working principle of a rotary roasting furnace is that through the continuous movement of its rotating cylinder, the material is fully contacted with the high-temperature gas flow, so as to achieve uniform heating and chemical reactions. The material is added into the rotary kiln from the kiln tail (high end), and the cylinder rotates at a certain speed. Due to the inclination and slow rotation of the cylinder, the material is roasted and moves forward in the kiln, and finally is discharged from the kiln head (low end). The heating system adopts electric heating radiation or sectional control of the combustion chamber, and the working temperature of each area of the furnace chamber is maintained by adjusting the power of the electric heating element or the flame size of the burner.

[0004] When the rotary roasting furnace roasts quartz stone fragments, the quartz stone may contain a small amount of impurities, and these impurities may chemically react with the material on the inner wall of the rotating cylinder at high temperatures, generating some viscous substances, resulting in the adhesion of the quartz stone fragments to the inner wall of the rotating cylinder. Moreover, if the temperature distribution in the rotary roasting furnace is uneven, it will cause local overheating of the quartz stone, and also cause the quartz stone fragments to melt or soften, thus adhering to the inner wall of the rotating cylinder. Furthermore, some of the adhered quartz stone fragments cannot fall off due to the inclination, causing waste of resources. If the rotary roasting furnace is not cleaned in a timely and effective manner during use, the remaining quartz stone fragments or other substances may become new adhesion points, making the subsequent roasted quartz stone more likely to adhere to the inner wall of the rotating cylinder, causing secondary adhesion, and thus reducing the output of quartz stone roasting.

[0005] Therefore, it is necessary to design an intelligent adjustable roasting furnace device that can prevent the adhesion of quartz stone fragments and has uniform heating. Summary of the Invention

By sequentially conveying the quartz stone fragments into the inner part of the material box, under the influence of the gravity of the quartz stone fragments, the material box slides downward and the second spring is completely compressed. When the material box slides downward, it can not only make the sieve plate just communicate with one end of the heat conduction tube, and a large amount of heat flows into the inner part of the material box to preheat the quartz stone fragments inside the material box, reducing the thermal expansion and contraction of the quartz stone fragments caused by the sharp temperature change during the roasting process, thereby reducing the cracking and damage of the quartz stone and maintaining the integrity of its structure.

Moreover, this quantitative transmission process of the quartz stone fragments is a pure mechanical quantitative transmission, without the need to use other complex sensors, control systems and other expensive electronic components and electric energy, achieving the effects of cost saving and energy conservation.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1-8 , the present invention provides a technical solution: A roasting furnace device for quartz stone production, including a support frame 1, a base 2 is fixedly connected to the upper side of the support frame 1, a collection mechanism 8 for storing high-temperature quartz stone fragments is provided on one side of the base 2, a heating mechanism 6 for uniformly roasting the used quartz stone fragments is provided on the upper side of the base 2, a slip ring seat 7 and a support tire 5 are sequentially arranged from left to right on the outside of the heating mechanism 6, the slip ring seat 7 and the support tire 5 are fixedly connected to the base 2, a feeding mechanism 4 for uniformly feeding the quartz stone fragments is provided inside the heating mechanism 6, a transmission mechanism 3 for driving the heating mechanism 6 to rotate is provided on one side of the heating mechanism 6, and a control cabinet 9 for adjusting the roasting temperature is provided on one side of the support frame 1.

[0023] Please refer to Figure 2 , the collection mechanism 8 includes a collection box 81 provided on one side of the base 2, two first guide plates 82 and two second guide plates 83 are fixedly connected to the inside of the collection box 81 respectively, the first guide plates 82 and the second guide plates 83 are arranged alternately, the first guide plates 82 are inclined downward to the left, and the second guide plates 83 are inclined downward to the right.

[0024] Specifically, after the quartz stone fragments are calcined, they first fall onto the upper surface of the first deflector 82 and slide downward by gravity. Immediately afterwards, they slide above the second deflector 83 and then slide downward again by gravity above the second deflector 83, and finally fall to the bottom of the collection box 81. There may be a certain adhesive force between the calcined quartz stone fragments, and the particles may become loose or some particles may fall off during the falling process, thereby changing the physical structure and appearance of the quartz stone. By shortening the falling height of the quartz stone fragments and reducing the impact force, the physical structure and appearance of the quartz stone are protected.

[0025] Please refer to Figure 3 and Figure 4 As shown in FIGS. and, the heating mechanism 6 includes a rotating cylinder 61 rotatably connected to the inner wall of the slip ring seat 7 and the support tire 5. A discharge channel 62 is fixedly connected to the lower side of one end of the rotating cylinder 61, and a feed channel 65 is fixedly connected to the upper side of the other end of the rotating cylinder 61. A heat preservation layer 66 is fixedly connected to the outer side of the rotating cylinder 61. A first electromagnetic coil 63 and a second electromagnetic coil 64 are respectively arranged on the left and right sides of the support tire 5. The first electromagnetic coil 63 and the second electromagnetic coil 64 are fixedly connected to the outer side of the heat preservation layer 66. A rotating shaft 67 is connected to the inside of the rotating cylinder 61 by bearings. Spiral blades 68 are evenly and fixedly connected to the outer side of the rotating shaft 67, and the spiral blades 68 are in contact with the inner wall of the rotating cylinder 61.

[0026] Specifically, the spiral blades 68 and the rotating shaft 67 are made of high-temperature resistant materials. The control cabinet 9 is used to adjust the heating power of the first electromagnetic coil 63 and the second electromagnetic coil 64, so as to adjust the heating temperature inside the rotating cylinder 61, and then bake the quartz stone fragments at an accurate temperature. The heat preservation layer 66 is used to keep the temperature inside the rotating cylinder 61. The support tire 5 is used to support the rotating cylinder 61 to make the rotation of the rotating cylinder 61 more stable. The feed channel 65 is used to convey the uncalcined quartz stone fragments into the rotating cylinder 61, and the discharge channel 62 is used to convey the calcined quartz stone fragments into the collection box 81.

[0027] The transmission mechanism 3 includes a reduction gearbox 33 fixedly connected to the upper side of the base 2. One side of the reduction gearbox 33 is fixedly connected with a motor 32, and the output end of the motor 32 is fixedly connected with the input end of the reduction gearbox 33. An adjusting assembly 31 is arranged at the output end of the reduction gearbox 33.

[0028] Specifically, the rotation of the output end of the motor 32 drives the rotation of the output end of the reduction gearbox 33, and then drives the connecting cylinder 311 to rotate.

[0029] Please refer to Figure 5 and Figure 6, the adjusting assembly 31 includes a rotating column 315 fixedly connected to the other end of the rotating cylinder 61. A connecting cylinder 311 is rotatably connected to the outer side of the rotating column 315. The other side of the connecting cylinder 311 is fixedly connected to the output end of the reduction gearbox 33. The other end of the rotating shaft 67 is fixedly connected to a U-shaped column 313, and a U-shaped groove is provided inside the U-shaped column 313.

[0030] A hydraulic cylinder 312 is fixedly connected inside the connecting cylinder 311. The output end of the hydraulic cylinder 312 penetrates through the connecting cylinder 311 and is fixedly connected to a clamping cylinder 314. The clamping cylinder 314 is arranged inside the U-shaped groove of the U-shaped column 313. A retaining plate 3141 is fixedly connected to the middle inside the clamping cylinder 314. First springs 3142 are respectively fixedly connected to both sides of the retaining plate 3141. The other end of each first spring 3142 is fixedly connected to a sliding column 3143.

[0031] Specifically, when the connecting cylinder 311 rotates, it drives the hydraulic cylinder 312 to rotate, thereby driving the clamping cylinder 314 to rotate.

[0032] The sliding column 3143 is slidably connected to the inner wall of the clamping cylinder 314. One end of the sliding column 3143 abuts against the inner wall of the rotating column 315. Two relief grooves are provided inside the rotating column 315. An inclined sliding surface 316 is provided inside each relief groove, and a right-angle surface 317 is provided at the other end of the inclined sliding surface 316.

[0033] Specifically, when it is necessary to rotate the spiral blade 68, the output end of the hydraulic cylinder 312 fully extends, and the clamping cylinder 314 is clamped into the U-shaped groove, thereby driving the rotating shaft 67 to rotate, and further driving the spiral blade 68 to rotate. Since the friction between the rotating shaft 67 and the rotating cylinder 61 plus the friction between the spiral blade 68 and the rotating cylinder 61 is less than the gravity of the rotating cylinder 61, when the rotating shaft 67 rotates, the rotating cylinder 61 will not be driven to rotate.

[0034] When it is necessary to rotate the rotating cylinder 61, the output end of the hydraulic cylinder 312 fully retracts, and the clamping cylinder 314 is driven to move. The sliding column 3143 moves along the inclined sliding surface 316. The first spring 3142 drives the sliding column 3143 to extend out of the clamping cylinder 314 through the elastic force until one end of the sliding column 3143 contacts the right-angle surface 317. The clamping cylinder 314 disengages from the U-shaped groove and is clamped into the relief groove, and starts to drive the rotating column 315 to rotate, and further drives the rotating cylinder 61 to rotate. Since the friction between the rotating shaft 67 and the rotating cylinder 61 plus the friction between the spiral blade 68 and the rotating cylinder 61 is less than the gravity of the rotating shaft 67, when the rotating cylinder 61 rotates, the rotating shaft 67 will not be driven to rotate, and the spiral blade 68 will not be driven to rotate either.

[0035] When it is necessary to roast the quartz stone fragments, the control cabinet 9 adjusts the power of the first electromagnetic coil 63 and the second electromagnetic coil 64 to heat the inside of the rotating drum 61. When the temperature reaches the temperature required for roasting the quartz stone, the quartz stone fragments enter the inside of the rotating drum 61 through the feeding channel 65. At the same time, the output end of the hydraulic cylinder 312 fully extends, and the clamping cylinder 314 is clamped into the U-shaped groove. The motor 32 starts to drive the clamping cylinder 314 to rotate, and then drives the spiral blade 68 to rotate. While the spiral blade 68 rotates, it conveys the falling quartz stone fragments. When one pile of quartz stone fragments reaches the leftmost position of the first electromagnetic coil 63, the output end of the motor 32 stops rotating, the output end of the hydraulic cylinder 312 fully retracts, the clamping cylinder 314 is clamped into the avoidance groove, and the output end of the motor 32 rotates again, indirectly driving the rotating drum 61 to rotate, driving the internal quartz stone fragments to tumble, so as to roast them evenly.

[0036] During the tumbling roasting process, through the limitation of each blade of the spiral blade 68, it effectively prevents the quartz stone fragments from tumbling to other areas when the rotating drum 61 rotates, resulting in the phenomenon that too many quartz stones are stacked in some areas, achieving the effect of uniform roasting. After the roasting is completed, the output end of the motor 32 stops rotating, the output end of the hydraulic cylinder 312 fully extends, the clamping cylinder 314 is clamped into the U-shaped groove, the motor 32 starts to drive the clamping cylinder 314 to rotate, and then drives the spiral blade 68 to rotate. While the spiral blade 68 rotates, it can not only drive the quartz stone fragments to be transported and dropped into the inside of the collection box 81, but also drive the spiral blade 68 to rotate to scrape off the quartz stone fragments adhering to the pipe wall, so that they all fall into the inside of the collection box 81, effectively preventing the phenomenon that some adhered quartz stone fragments cannot fall due to inclination, resulting in waste of resources.

[0037] Embodiment 2: When feeding the inside of the rotating drum 61, since the amount of quartz stone fragments transported each time cannot be quantified, the number of quartz stone fragments in each area inside the rotating drum 61 is different. In the area with more quartz stone fragments, the reaction may be insufficient due to insufficient heat, while in the area with fewer quartz stone fragments, by-products may be generated due to too high temperature. Moreover, the uneven distribution of quartz stone fragments may cause the quartz stone fragments in some local areas to be too dense, hindering the uniform distribution of heat and gas, thus affecting the roasting efficiency. Therefore, the following structure is designed to solve the above technical problems.

[0038] Please refer to Figure 7 and Figure 8, the feeding mechanism 4 includes a heat conduction tube 611 penetrating and connected to the inner wall of the feeding channel 65. The other end of the heat conduction tube 611 sequentially penetrates through the heat insulation layer 66, the rotating cylinder 61 and is fixedly connected to the rotating cylinder 61. On the upper and lower sides inside the feeding channel 65, a limiting inclined plate 41 and a guiding slide plate 45 are fixedly connected respectively. The limiting inclined plate 41 and the guiding slide plate 45 have the same inclination angle, and a material box 48 is arranged between the limiting inclined plate 41 and the guiding slide plate 45. The material box 48 is slidably connected to the inside of the feeding channel 65.

[0039] Specifically, the heat conduction tube 611 is used to export the heat inside the rotating cylinder 61 to the outside. The limiting inclined plate 41, the guiding slide plate 45 and the limiting triangular plate 42 are all used to guide the material box 48, so that the material box 48 and the baffle 47 slide between the limiting inclined plate 41 and the guiding slide plate 45. Above the limiting inclined plate 41 and the limiting triangular plate 42 is used to guide the quartz stone fragments.

[0040] One side of the material box 48 is fixedly connected with a baffle 47, and the upper side of the baffle 47 is attached to the lower side of the limiting inclined plate 41. A sieve plate 46 is fixedly connected to the inner wall of the material box 48. The lower side of the material box 48 is hinged with a lower box cover 49, and the lower side of the lower box cover 49 is attached to the upper side of the guiding slide plate 45. The other side of the material box 48 is fixedly connected with a slide plate 461, and one side of the slide plate 461 presses against one end of the heat conduction tube 611.

[0041] Specifically, the sieve plate 46 is used to prevent the quartz stone fragments from falling out of the inside of the material box 48, and the lower box cover 49 is used to block the quartz stone fragments to prevent the quartz stone fragments from falling downward when moving.

[0042] On the other side of the material box 48, two second springs 43 are also fixedly connected, and the other end of each second spring 43 is fixedly connected to the inner wall of the feeding channel 65. A touch button 44 is arranged inside each second spring 43, and the touch button 44 is fixedly connected to the inner wall of the feeding channel 65. A limiting triangular plate 42 is arranged on the upper side of the second spring 43, and the limiting triangular plate 42 is fixedly connected to the inner wall of the feeding channel 65. There is a material passing port between the limiting triangular plate 42 and the limiting inclined plate 41, and the upper side of the material box 48 is attached to the lower side of the limiting triangular plate 42.

[0043] Specifically, the second spring 43 is used to hold up the material box 48 to prevent the empty material box 48 from sliding down. After the material box 48 is filled with materials, the second spring 43 will be gradually compressed. When the second spring 43 is completely compressed, one side of the material box 48 will press on the touch end of the touch button 44. The touch button 44 is used to send a signal to the motor 32 to control the rotation of the output end of the motor 32.

[0044] In the initial state, the material box 48 is supported by the spring force of the second spring 43 and is located below the material passing opening. When feeding is required, the staff pours the quartz stone fragments into the interior of the feeding channel 65. The quartz stone fragments fall along the upper inclined surfaces of the limiting inclined plate 41 and the limiting triangular plate 42. The quartz stone fragments successively fall into the interior of the feeding box 48. A large amount of heat generated inside the rotating cylinder 61 is stored in the heat conduction tube 611. At this time, since it is blocked by the sliding plate 461, the heat inside the heat conduction tube 611 cannot be discharged. The heat generated inside the rotating cylinder 61 is stored and insulated inside the heat conduction tube 611 until the interior of the material box 48 is filled with quartz stone fragments. At this time, the weight of the material box 48 plus the quartz stone fragments is much greater than the frictional force between the material box 48 and each structure plus the spring force of the second spring 43.

[0045] At this time, the second spring 43 is gradually compressed, and the material box 48 slides along the limiting inclined plate 41, the guiding sliding plate 45, and the limiting triangular plate 42 until the spring force of the second spring 43 plus the frictional force between the material box 48 and each structure is equal to the weight of the material box 48 plus the quartz stone fragments. At this time, the material box 48 no longer slides downward, and the sieve plate 46 just communicates with one end of the heat conduction tube 611. A large amount of heat flows into the interior of the material box 48 to preheat the quartz stone fragments inside the material box 48. The baffle plate 47 completely blocks the material passing opening, and the quartz stone fragments cannot pass through the material passing opening. Since the lower box cover 49 no longer fits with the guiding sliding plate 45 below, the lower box cover 49 rotates and opens, and the quartz stone fragments inside the material box 48 fall downward and enter the rightmost side inside the rotating cylinder 61.

[0046] Meanwhile, the second spring 43 is completely compressed, and one side of the material box 48 presses against the pressing end of the pressing button 44. The pressing button 44 emits a signal to the motor 32. The output end of the motor 32 rotates to drive the spiral blade 68 to rotate, thereby transporting a box of fallen quartz stone fragments until the quartz stone fragments are no longer below the feeding channel 65. The output end of the motor 32 stops rotating, and the transportation of the next batch of quartz stone fragments begins, so as to evenly transport each box of quartz stone fragments into the interior of the rotating cylinder 61.

[0047] By sequentially conveying the quartz stone fragments into the interior of the material box 48, under the influence of the gravity of the quartz stone fragments, the material box 48 slides downward and the second spring 43 is completely compressed. When the material box 48 slides downward, it can not only make the sieve plate 46 just communicate with one end of the heat conduction tube 611, a large amount of heat flows into the interior of the material box 48, preheating the quartz stone fragments inside the material box 48, reducing the thermal expansion and contraction of the quartz stone fragments during the roasting process due to the sharp temperature change, thereby reducing the cracking and damage of the quartz stone and maintaining the integrity of its structure. It can also send a certain amount of quartz stone fragments into the interior of the rotary drum 61 when the lower box cover 49 loses support, for uniform feeding, enabling uniform heating during the subsequent roasting of the quartz stone, effectively preventing the phenomenon that the quartz stone fragments are too dense in some local areas due to uneven distribution of the quartz stone fragments, which hinders the uniform distribution of heat and gas and thus affects the roasting efficiency. Moreover, this quantitative transmission process of the quartz stone fragments is a pure mechanical quantitative transmission, without the need to use other complex sensors, control systems and other expensive electronic components and electric energy, achieving the effects of cost saving and energy conservation.
