Description

Technical Field

[0001] The invention relates to the technical field of roasting furnaces, in particular to intelligent adjustable roasting furnace equipment. Background Art

[0002] A roasting furnace is an industrial equipment used to heat treat various solid materials to change their physical or chemical properties. It is widely used in many industries such as metal processing, mineral processing, ceramic manufacturing and chemical industry. The roasting process usually involves oxidation, pyrolysis, reduction, halogenation and other reactions, and sometimes catalysts are added. A roasting furnace is also used when quartz sand needs to be purified. Impurities in quartz sand, especially lattice impurities, can be removed by high-temperature roasting.

[0003] Roasting mainly includes the following steps: the material to be treated enters the feed port of the roasting furnace, and after preheating and drying, enters the high-temperature roasting area; in the furnace, the high-temperature flame generated by the combustion of fuel heats the material, causing its internal chemical reaction; the treated material flows out from the discharge port, and the exhaust gas is discharged through the chimney or other exhaust system. Quartz sand is roasted once or twice according to the purification needs. One time is used to remove volatile impurities and some structural water in the quartz sand. When the quartz sand needs to be deeply purified, a second roasting is required, which is also called chlorination roasting. It is a process of converting the impurity component ions into low-boiling chlorides, and then separating the impurity components.

[0004] The existing quartz sand roasting will be transported to the roasting furnace after material pretreatment, and roasted according to the purification requirements. However, the particle size of quartz sand affects its roasting effect. Quartz sand with larger particles may expand or melt unevenly due to uneven heating during the roasting process, which may affect the quality of the final product. Quartz sand with smaller particles may be easier to achieve uniform heating. Therefore, the temperature and chlorination agent requirements of large-particle quartz sand are different from those of small-particle quartz sand. Summary of the invention

DETAILED DESCRIPTION

[0032] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-10 The present invention provides a technical solution: an intelligent adjustable roasting furnace device, comprising a furnace body 1, a conveying mechanism 2, an exhaust gas output mechanism 3 and a feeding mechanism, wherein the conveying mechanism 2 is arranged in the furnace body 1, the conveying mechanism 2 comprises an upper conveyor belt 21 and a lower conveyor belt 22, the exhaust gas output mechanism 3 is erected on the upper side of the furnace body 1, the feeding mechanism is arranged at the feeding port of the furnace body 1 and cooperates with the conveying mechanism 2, the feeding mechanism comprises a mounting frame 4, a screening component 5, a dividing component 6 and a feeding component 7, wherein the screening component 5 is arranged in the mounting frame 4, for screening impurities and quartz sand materials of different sizes, the dividing component 6 is arranged at the lower side of the screening component 5, for conveying the quartz sand material separated by the screening component 5 to the upper conveyor belt 21 and the lower conveyor belt 22, and the feeding component 7 is arranged in conjunction with the dividing component 6, for deep purification of the required chlorination agent;

[0034] The screening material assembly 5 includes a screening shaft 51, a grid cylinder 52 and a separating cylinder 53, wherein the screening shaft 51 is rotatably set on the mounting frame 4, the grid cylinder 52 is sleeved on the screening shaft 51, the grid cylinder 52 includes mounting plates 521 on both sides, a plurality of ribs 522 are connected between the mounting plates 521, a driving tooth 523 is rotatably set on the surface of the mounting plates 521, the driving tooth 523 is connected to a motor 524, the separating cylinder 53 includes gear cylinders 531 on both sides, the gear cylinders 531 cooperate with the driving tooth 523, a plurality of fins 532 are connected between the gear cylinders 531, the fins 532 are inserted between two ribs 522, and a plurality of elastic ropes 525 are connected between the fins 532 and adjacent ribs 522.

[0035] Supplementary explanations based on the above structure are as follows: when the motor 524 is started, the gear cylinder 531 can be driven to deflect by the driving tooth 523, so that the fin 532 is close to or away from the ribs 522 on both sides. When the fin 532 is close to the rib 522 on one side, a larger opening will be formed between the fin 532 and the rib 522 on the other side, which can allow all quartz sand materials to enter and exit. When the fin 532 moves between the ribs 522 on both sides, it will form several small openings in conjunction with the elastic rope 525, which can allow small volumes of quartz sand materials to enter and exit; the cross-sectional height of the fin 532 is greater than that of the rib 522. The part of the fin 532 extending from the surface of the rib 522 can assist in feeding, and the part of the fin 532 extending into the surface of the rib 522 can help stir the material to prevent caking.

[0036] Furthermore, the sieve shaft 51 is a hollow structure and has several sieve holes on its surface. The aperture of the sieve holes is smaller than the particle size of the quartz sand material. One end of the sieve shaft 51 is connected to a motor 54, and the other end of the sieve shaft 51 is covered with a turn-out sleeve 55. The turn-out sleeve 55 is fixed on one side of the mounting frame 4 and is externally connected to an air pump.

[0037] In actual operation, the motor 2 54 is used to drive the sieve shaft 51 to rotate and turn the internal materials, and the air pump extracts the fine impurities remaining in the materials through the sieve holes of the sieve shaft 51 to improve the subsequent roasting quality.

[0038] In one embodiment, Figures 9-10 As shown, deep grooves 526 are provided on both sides of the rib 522 to cooperate with the elastic rope 525, and a pressure sensing module 527 is laid at the bottom of the deep groove 526. A spring 528 is connected between the elastic rope 525 and the pressure sensing module 527. When the fin 532 rotates, the elastic ropes 525 on both sides will be pulled. The pressure sensing module 527 determines the deflection state of the fin 532 or whether there is material jamming through the force brought by the spring 528. The spring 528 is used to provide buffering and stretching margin to prevent the elastic rope 525 from breaking or the elastic force from failing.

[0039] like Figure 3 As shown, the material dividing assembly 6 includes two groups of pressure wheels 61, a material guide plate 62 and an arc-shaped baffle plate 63, wherein the pressure wheels 61 are respectively mounted on the upper conveyor belt 21 and the lower conveyor belt 22, and one end of the pressure wheel 61 is connected to a driving motor for rotating the pressure wheel 61 to flatten the material, the material guide plate 62 is fixed in the mounting frame 4 and is arranged in conjunction with the pressure wheel 61 and the screening assembly 5, for guiding the material to the corresponding conveyor belt, and the arc-shaped baffle plate 63 is attached to one side of the screening assembly 5, for preventing the material from falling out of the screening assembly 5.

[0040] Preferably, the feed inlet of the guide plate 62 is provided with a switch valve.

[0041] The feeding assembly 7 is mounted on the pressing wheel 61, and includes a feed barrel 71, an adjustment plate 72 and a push rod 73, wherein the feed barrel 71 is used to introduce the chlorinating agent, the bottom of the feed barrel 71 is set to fit the curvature of the surface of the pressing wheel 61 and the surface is grooved, the adjustment plate 72 is slidably matched with the groove and the plate surface is consistent with the curvature of the surface of the pressing wheel 61, and the driving end of the push rod 73 is connected to the adjustment plate 72, which is used to adjust the distance between the adjustment plate 72 and the pressing wheel 61, thereby adjusting the input amount of the chlorinating agent.

[0042] In actual operation, the pressing wheel 61 is used to flatten the quartz sand particles on the conveyor belt to ensure uniform laying and improve the roasting quality. During the rotation of the pressing wheel 61, the chlorinating agent will be driven to be laid on the surface of the material. The laying amount is adjusted according to the distance between the adjustment plate 72 and the pressing wheel 61, so that the chlorinating agent can be evenly added, further improving the roasting quality.

[0043] The exhaust gas output mechanism 3 includes a sealed box 31 and several groups of exhaust devices 32, wherein the sealed box 31 is externally connected to gas delivery pipes on both sides, and a gas monitoring device is arranged inside the sealed box 31 for real-time analysis of the exhaust gas composition. The exhaust device 32 adopts a combination of a fan and an air duct, wherein the air inlet of the air duct is connected to the inside of the furnace body 1, and the air outlet of the air duct is connected to the sealed box 31, and the fan is arranged at the air outlet of the air duct.

[0044] Preferably, the air inlets of the air ducts are arranged at staggered heights to fully extract the waste gas produced in the furnace body 1. The upper conveyor belt 21 is used to convey large particle materials, and the lower conveyor belt 22 is used to convey small particle materials.

[0045] The specific implementation methods are as follows:

[0046] Step 1: Feeding, the operator puts a certain amount of quartz sand material and chlorinating agent into the screening component 5 and the feeding component 7 respectively;

[0047] Step 2: Material separation: The screening component 5 turns over the quartz sand material, extracts the fine impurities inside, and transports the quartz sand to the upper conveyor belt 21 and the lower conveyor belt 22 according to the particle size;

[0048] Step 3: Spreading the material, the pressing wheel 61 flattens the material on the conveyor belt, and adds the chlorinating agent according to the purification requirements;

[0049] Step 4: roasting, the conveying mechanism 2 transports the material to the furnace body 1 for roasting;

[0050] Step 5: waste gas treatment. The waste gas output mechanism 3 extracts the waste gas produced during roasting. At the same time, the gas monitoring equipment detects the waste gas composition in real time to facilitate analysis and adjustment.

[0051] Specifically, in step 1, when the screening component 5 is fed, the motor 1 524 drives the fin 532 to be close to the rib 522 on one side, and determines whether the movement is in place based on the value detected by the pressure sensing module 527 corresponding to the rib 522 on the other side. The pressure value range here is set manually.

[0052] In step 2, after feeding, motor 1 524 drives fin 532 to deflect to the middle of two ribs 522, and also judges according to the values ​​detected by pressure sensing modules 527 corresponding to both sides, that is, when the detected values ​​are almost equal, it can be judged that the movement is in place, at this time only small particles can pass, motor 2 54 drives screening component 5 to rotate, firstly remove the fine impurities mixed in the material; then the guide plate 62 corresponding to the lower conveyor belt 22 forms a passage, and the screening component 5 continues to rotate, at this time the material in the small particle range will be transported to the lower conveyor belt 22 along the channel formed by the guide plate 62; secondly, after the small particle material is output, the guide plate 62 corresponding to the lower conveyor belt 22 closes the passage, and the guide plate 62 corresponding to the upper conveyor belt 21 forms a passage, and the screening component 5 outputs all the remaining material inside.

[0053] Furthermore, the pressure sensing module 527 can be used to detect whether there is material blockage, that is, during the normal deflection of the fin 532, if material blockage occurs, the fin 532 will be stuck and the pressure sensing module 527 cannot detect the continuously changing force signal. At this time, the fin 532 can be driven to deflect back and forth to clear the blockage.

[0054] In step 3, if the chlorinating agent does not need to be added, the push rod 73 pushes the adjustment plate 72 to fit the surface of the pressing wheel 61 to block the passage of the chlorinating agent; if the chlorinating agent needs to be added, the push rod 73 pulls the adjustment plate 72 away from the surface of the pressing wheel 61 for a distance, and the distance is adjusted according to the actual ratio;

[0055] Furthermore, according to the exhaust gas composition detection results in step five, the input amount of the chlorinating agent can be adjusted. If the chloride content in the exhaust gas is lower than expected, it may mean that the amount of the chlorinating agent is insufficient, and the spacing can be increased to increase the average input of the chlorinating agent; if the chloride content in the exhaust gas is within the expected range, it means that the chlorinating agent is appropriate and no further adjustment is required; if the chloride content in the exhaust gas is higher than expected, it may mean that the amount of the chlorinating agent is excessive, and the spacing can be reduced to reduce the average input of the chlorinating agent.

[0056] In step four, the roasting temperature needs to be set in layers. The temperature range set for the small-particle material at the lower conveyor belt 22 is within the normal setting range, because quartz sand with smaller particle size is easier to achieve uniform heating; and the temperature range set for the large-particle material at the upper conveyor belt 21 is larger than the normal setting range. Quartz sand with larger particle size may be heated unevenly during the roasting process. At the same time, due to the rising hot air flow, the material at the upper layer is heated to a higher temperature.
