Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, and particularly relates to an intelligent red ore hitting device for a belt conveyor for conveying high-temperature materials. Background Technique

[0002] Belt conveyors are the most common equipment in the metallurgical industry, especially in the front-iron area. They have the characteristics of large conveying capacity, long conveying distance, simple layout, and good stability, and have always been widely praised.

[0003] At present, during the production processes of sintering and pelletizing, process fluctuations, changes in batch and type of materials, as well as start-up and shutdown, will cause the temperature of the finished ore of the sintering and pelletizing ring coolers to be on the high side. The belt is affected by high temperature and its service life is reduced. Sometimes, when red ore drops, it will also cause the belt to catch fire, burn out the equipment, and even cause a fire, resulting in greater production accidents. Therefore, the control of the red ore temperature on the finished product line is particularly important. Originally, general operators controlled the temperature reduction by manually operating the valves on site according to experience. Due to being too extensive, it is extremely easy to cause accidents such as belt scalding and belt catching fire. There is a need for a complete set of belt conveyor red ore hitting devices to scientifically and reasonably control the red ore on the belt conveyor.

[0004] To solve the problem of the extensive belt protection management of the current sintering and pelletizing finished product belt conveyors that judge according to experience and manually hit red ore, the space in the belt corridor is narrow, and the amount of water injection depends entirely on experience control, which poses a great safety risk to the operation of the equipment. At the same time, it causes fluctuations in the output and quality of sintered ore. Therefore, there is an urgent need to design an intelligent red ore hitting device for a belt conveyor for conveying high-temperature materials to solve the problems of great safety risks and potential safety hazards of belt burns existing in the manual control of the current sintering and pelletizing finished product belt conveyors.

[0035] The following will further describe in detail the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0036] As Figures 1-8 shown, an intelligent red ore hitting device for a belt conveyor for conveying high-temperature materials includes a temperature-measuring thermal imager system 1, a tail water spraying system 3 for the belt conveyor, a head water spraying system 4 for the belt conveyor, a head hopper water spraying system 5, and an alarm control system 6. The temperature-measuring thermal imager system 1 is provided with a temperature-measuring thermal imager 102. The temperature-measuring thermal imager 102 is installed above the belt conveyor 11 and faces the incoming material direction. The tail of the belt conveyor 11 is located below the feed hopper 12, and an outlet hopper 13 is provided below the head of the belt conveyor 11.

[0037] The tail water spraying system 3 for the belt conveyor is installed above the tail of the belt conveyor 11. The water spraying nozzles of the tail water spraying system 3 for the belt conveyor are located at the rear side of the feed hopper 12. The head water spraying system 4 for the belt conveyor is installed above the head of the belt conveyor 11. The atomizing nozzles of the head water spraying system 4 for the belt conveyor are located at the front side of the temperature-measuring thermal imager 102. The head hopper water spraying system 5 is installed on one side of the outlet hopper 13. The atomizing nozzles of the head hopper water spraying system 5 extend into the interior of the outlet hopper 13.

[0038] When the temperature-measuring thermal imager 102 on the top of the belt corridor 101 detects high-temperature materials on the belt conveyor 11 in real time, a reasonable and targeted solution is judged based on the database stored in the alarm control system 6 and historical experience, and a series of measures such as reverse water spraying through the tail water spraying system 3 for the belt conveyor, the head water spraying system 4 for the belt conveyor, and the head hopper water spraying system 5 are taken to eliminate the safety hazards brought by sintered and pelletized red ore.

[0039] The temperature-measuring thermal imager 102 adopts a water-cooled self-cleaning high-temperature-resistant temperature-measuring thermal imager. The temperature-measuring thermal imager 102 is installed in the temperature-measuring thermal imager housing 110. The double-layer 204 stainless steel structure of the temperature-measuring thermal imager housing 110 is a cooling sandwich cavity. Cooling water circulates through the sandwich to achieve the cooling effect. The front end cover forms an air curtain through compressed air to play a role in dust prevention and self-cleaning. At the same time, 304 stainless steel has good corrosion resistance. This cooling system is a reliable guarantee for the normal operation of the temperature-measuring thermal imager 102 in a high-temperature and harsh environment.

[0040] The upper part of the temperature-measuring thermal imager housing 110 is connected to a sliding plate 103 through a support rod. The sliding plate 103 is slidably connected in the chute 105 of the installation sliding seat 104. The installation sliding seat 104 is fixed on the top of the belt corridor 101. A rectangular groove 109 is provided on one side of the chute 105. The rectangular groove 109 is used to control the disassembly of the sliding plate 103 in the chute 105.

[0041] One side of the skateboard 103 is fixedly connected to the adapter plate 106. The adapter plate 106 is provided with a through hole. The connecting rod screw 107 passes through the through hole and is fixed by a nut. The other end of the connecting rod screw 107 is connected to the clamping block 108 by a nut. The clamping block 108 adopts a U-shaped structure and is fixed inside the mounting slide 104. The connecting rod screw 107 adjusts and fixes the horizontal position of the temperature measuring thermal imager above the belt conveyor.

[0042] The cooling sandwich cavity is provided with a water inlet and a water outlet. The water inlet is connected to the water tank 113 through the water inlet pipe 114. A water pump 115 is installed on the water inlet pipe 114. The water outlet is connected to the water tank 113 through the return water pipe 116. The water pump 115 controls the circulation of the cooling water between the water tank 113 and the shell 110 of the temperature measuring thermal imager. The temperature measuring thermal imager 102 is connected to the control cabinet 117 of the alarm control system 6 through a cable, and a high-temperature wire protecting pipe is sleeved outside the cable.

[0043] The shell 110 of the temperature measuring thermal imager is provided with a dust removal air outlet 111. The dust removal air outlet 111 communicates with the temperature measuring thermal imager 102 and does not communicate with the cooling sandwich cavity. The dust removal air outlet 111 is connected to the air compressor 112 through an air delivery pipe.

[0044] To achieve a better cooling effect of the cooling water on the body of the temperature measuring thermal imager 102, a separate constant temperature cooling water tank 113 is established. When constructing, the volume of the cooling water tank 113 needs to be able to meet the water volume in the cooling sandwich cavity and the connecting water pipeline of the temperature measuring thermal imager 102 connected to it by 2 times. As much as possible, softened water or demineralized water is used to prevent corrosion or structure of the pipeline along the line. The cooling water flow needs to be maintained between 0.3 - 0.6 L / s, the water temperature needs to be ≤ 35 °C, and a chiller or other methods are used for cooling.

[0045] The connecting cooling water pipe needs to be able to withstand a water pressure not lower than 0.2 Mpa. When the pressure bearing cannot be met, the diameter of the water pipe needs to be thickened to increase the runoff area. The connecting pipe of the cooling sandwich cavity adopts a metal hose + quick connector, which is convenient for the maintenance and replacement of the temperature measuring thermal imager 102. For the water pressure of 0.1 Mpa in the cooling sandwich cavity, a pressure reducing valve is installed before the water inlet of the cooling sandwich cavity to prevent the temperature measuring thermal imager 102 from being damaged due to water pressure.

[0046] When selecting the cooling water pump 115, equipment with a corresponding power needs to be selected according to the pipe laying length and the volume of the cooling sandwich cavity connected. The power selection of the chiller needs to be able to meet the requirement of cooling the water in the water tank 113 below 35 °C.

[0047] For the large environmental dust in the finished belt corridor 101, compressed air can be connected to the window for dust removal. The dust removal air pressure is 0.1 - 0.4 Mpa. Connect the compressed air pipeline and install an air compressor 112 as a standby machine. Once the pipeline network pressure is insufficient, the air compressor 112 can be started at any time.

[0048] The tail belt conveyor water spraying system 3 includes solenoid valve 1 8, water spraying nozzles and water injection pipe 1. The water spraying nozzles are installed on the water outlet side of water injection pipe 1, and solenoid valve 1 8 is installed on water injection pipe 1. The water inlet side of water injection pipe 1 is connected to the fire water pipe 2; the belt is wetted and cooled in advance before contacting the material to prevent the material from scalding the belt.

[0049] The water spraying nozzles of the tail belt conveyor water spraying system 3 select substances such as water spraying or high-temperature resistant solvents to reduce the surface temperature of the belt, so as to form an isolation layer between the belt surface and the sintered and pellet ore surfaces.

[0050] The head belt conveyor water spraying system 4 includes a booster pump 7, solenoid valve 2 9, water injection pipe 2 and atomizing nozzles. The atomizing nozzles are installed on the water outlet side of water injection pipe 2, and the booster pump 7 and solenoid valve 2 9 are installed on water injection pipe 2. The water inlet side of water injection pipe 2 is connected to the fire water pipe 2; this is the key part for cooling the sintered ore, and it is the key part for the cooling effect of the sintered and pellet ore.

[0051] When the tail belt conveyor temperature measuring thermal imager 102 detects the appearance of sintered and pellet red ore, it feeds back to the alarm control system 6 of the temperature measuring thermal imager 102. Through the calculation of the belt speed of the belt conveyor 11 and the distance between the temperature measuring thermal imager 102 and the head belt conveyor water spraying system 4, when the red ore enters the water spraying area, solenoid valve 2 9 opens and the booster pump 7 starts, and the non-powered self-rotating atomizing nozzles spray the fire water onto the surface of the high-temperature sintered ore for cooling.

[0052] The booster pump 7 is driven by variable frequency speed regulation, and the rotation speed of the pump 7 and the opening degree of solenoid valve 2 9 are adjusted in real time according to the temperature of the sintered and pellet ore detected by the temperature measuring thermal imager 102.

[0053] The head hopper water spraying system 5 includes solenoid valve 3 10, water injection pipe 3 and atomizing nozzles. The atomizing nozzles are installed on the water outlet side of water injection pipe 3, and solenoid valve 3 10 is installed on water injection pipe 3. The water inlet side of water injection pipe 3 is connected to the fire water pipe 2.

[0054] When the amount of sintered red ore and the temperature of the sintered ore are very high and the particle size is large, the head belt conveyor water spraying system 4 cannot cool the part close to the belt. During the transfer of the sintered ore at the head hopper of the belt conveyor, the water spraying device cools the sintering machine again by spraying the reverse side of the sintered ore.

[0055] The opening position of the atomizing nozzles is obliquely upward. Since there is a large amount of dust at the head hopper, the non-powered self-rotating atomizing nozzles are regularly purged with compressed air.

[0056] The atomizing nozzles of the belt head water injection system 4 and the atomizing nozzles of the head hopper water injection system 5 both adopt non-powered self-rotating atomizing nozzles with the same structure. The atomizing nozzle includes a nozzle branch pipe 401, a nozzle housing 402, a nozzle rotor 403, and a nozzle positioning sleeve 404. The end of the nozzle branch pipe 401 is installed with the nozzle housing 402, the end of the nozzle housing 402 is installed with the nozzle rotor 403, the outer side of the nozzle housing 402 is connected with the nozzle positioning sleeve 404, and the nozzle positioning sleeve 404 wraps around the outer sides of the nozzle rotor 403 and the nozzle housing 402. The non-powered self-rotating atomizing nozzle includes a nozzle branch pipe 401 for connecting with a water adding device. A swirl chamber, a centrifugal chamber, and a nozzle orifice are sequentially arranged in the nozzle branch pipe 401 along the direction of water flow. The valve core can rotate in the swirl chamber, and the water flow forms a water flow channel through the deflector plate of the valve core, driving the valve core to rotate, thereby increasing the atomization area of the atomizing nozzle, having better uniformity, and better wetting and cooling of sintered ore and pellet ore.

[0057] A nozzle protection mechanism is installed at the atomizing nozzle of the head hopper water injection system 5. The nozzle protection mechanism includes a nozzle 501 and a protective lining plate 510. The protective lining plate 510 is blocked on the side wall of the discharge hopper 13. The upper part of the outer side of the protective lining plate 510 is rotatably installed on the equipment foundation frame through a fixed hinge 508, and the lower part of the outer side of the protective lining plate 510 is rotatably connected to the telescopic rod of a linear motion mechanism 511 through a movable hinge 509. The linear motion mechanism 511 adopts a telescopic cylinder or a telescopic hydraulic cylinder. The base of the linear motion mechanism 511 is rotatably installed on the equipment foundation frame through a fixed hinge 512. The linear motion mechanism 511 controls the flipping of the protective lining plate 510 through the telescopic rod and sets an opening at the lower part.

[0058] The nozzle 501 is installed on the upper part of a nozzle support 502. The nozzle 501 is connected with a water inlet pipe 505. The rear part of the water inlet pipe 505 is a hose with a reserved length. The water inlet pipe 505 is fixedly installed on the nozzle support 502. The nozzle support 502 is fixedly connected with a slider 504. The slider 504 is slidably connected with a fixed guide rail 503. The bottom of the fixed guide rail 503 is installed on the equipment foundation frame. A rack 506 is installed on the upper part of the nozzle support 502. The rack 506 is meshed and connected with a gear 507. The gear 507 is installed on the output shaft of a motor reducer. The motor reducer is fixedly installed on the equipment foundation frame. The motor reducer controls the nozzle 501 to extend into and out of the opening formed at the lower part of the protective lining plate 510.

[0059] When the amount of sintered red ore and the particle size of the sinter are large, the control system first immediately controls the linear motion mechanism 511 to perform an extension action, and the protective lining plate 510 rotates clockwise to create a space for the water injection mechanism to flow out; then, driven by the motor reducer, the gear 507 rotates clockwise, driving the rack 506, the nozzle support 502, and the nozzle 501 to move obliquely downward along a straight line through the space vacated by the protective lining plate 510 to a position below the material surface where the nozzle 501 is perpendicular to the moving direction of the material surface. The solenoid valve three 10 immediately operates to achieve the cooling effect on the reverse side of the sintered ore.

[0060] When the temperature sensor detects that the temperature drops to a reasonable value, the solenoid valve three 10 closes, the motor reducer drives the gear 507 to rotate, driving the driving rack 506, the nozzle support 502, and the nozzle 501 to reset; the linear motion mechanism 511 contracts, driving the protective lining plate 510 to reset.

[0061] The solenoid valve one 8, the solenoid valve two 9, the solenoid valve three 10, the booster pump 7, and the temperature measurement thermal imager 102 are all connected to the control cabinet 117 of the alarm control system 6 through cables.

[0062] A working method of an intelligent red ore hitting device for a belt conveyor for transporting high-temperature materials includes the following steps:

[0063] 1. The water-cooled self-cleaning high-temperature resistant temperature measurement thermal imager 102 above the belt conveyor 11 continuously detects the temperature on the surface of the sintered pellet ore transported on the belt conveyor 11, and the collected temperature data is fed back to the control cabinet 117 connected to the temperature measurement thermal imager 102.

[0064] 2. The control cabinet 117 sorts out the temperature data fed back by the temperature measurement thermal imager 102, and checks whether the temperature exceeds the safe temperature by comparing with the database sorted and stored in the early stage. The alarm control system 6 accumulates the temperature measurement historical data of the on-site temperature measurement thermal imager 102 and presets the relevant parameters of the automatic control program, specifically including setting the first gear set temperature T1, the second gear set temperature T2, the third gear set temperature T3, the fourth gear set temperature T4, and the fifth gear set temperature T5. If it does not exceed, the intelligent red ore hitting device continues to monitor production; once it exceeds the protection value, the over-temperature range is confirmed. At the same time, the solenoid valve one of the belt tail watering system is opened, and the belt is wetted before receiving the material. The fed-back temperature data is sorted out, and it is checked whether the temperature value exceeds the safe temperature by comparing with the database sorted and stored in the early stage. If it does not exceed, the intelligent red ore hitting device continues to monitor production; once it exceeds the protection value, the over-temperature range is confirmed. At the same time, the solenoid valve one of the belt tail watering system is opened, and the belt is wetted before receiving the material.

[0065] 3. There is a certain distance between the belt head watering system 4 and the temperature measurement thermal imager 102. As the over-temperature sintered pellet ore is detected and enters the belt head watering system 4, the solenoid valve two 9 is opened, and the booster pump 7 confirms whether to start according to the on-site feedback data to forcibly cool the sintered pellet ore.

[0066] 4. When the temperature detected by the temperature measuring thermal imager 102 exceeds T5, the linear running mechanism 511 controls the protective lining plate 510 to form an opening on the outer wall of the discharge funnel 13, the motor reducer controls the spray head 501 to extend into the discharge funnel 13, the head funnel water spraying system 5 of the belt conveyor 11 is fully opened, the opening degree of all solenoid valves is 100%, and the frequency of the booster pump 7 is 50HZ.

[0067] 5. According to the temperature data of the sintered pellets detected by the temperature measuring thermal imager 102, conversely, close all corresponding solenoid valves and the booster pump 7.

[0068] 6. When the temperature of the material detected by the temperature measuring thermal imager 102 is less than T1 for 30 seconds, the intelligent red ore spraying device for the sintered pellet belt conveyor stops.

[0069] The specific steps of the automatic control program preset by the alarm control system 6 are as follows:

[0070] Compare the material temperature T with the preset T1. If T < T1, close the solenoid valve 1 8 and stop the spraying operation on the material surface.

[0071] If T ≥ T1 and T < T2, the solenoid valve 2 9 of the belt head water spraying system 4 is opened to 30%, and the opening degree of the solenoid valve 1 8 of the belt tail water spraying system 3 is 50%.

[0072] If T ≥ T2 and T < T3, the solenoid valve 2 9 of the belt head water spraying system 4 is opened to 60%, and the opening degree of the solenoid valve 1 8 of the belt tail water spraying system 3 is 80%.
