Description

Technical Field

[0001] The utility model relates to a mixing and batching vehicle, in particular to a mobile batching vehicle for mixing iron ore at a port, belonging to the technical field of ironmaking raw material equipment. Background Art

[0002] In the prior art, the technical and economic indicators of blast furnace ironmaking are closely related to the stability of raw material composition. Production practice shows that the fluctuation of the grade of iron-containing raw materials is reduced by 0.1%, the fuel consumption of sintering production is reduced by 0.6% to 1.2%, the output of sintered ore is increased by 0.28%, the output of pig iron is increased by 0.3% to 0.6%, the coke ratio into the furnace is reduced by 0.2% to 0.46%, the amount of iron slag is reduced by 0.46%, and the amount of furnace dust is reduced by 0.8%. However, the ore raw materials of steel mills at present are often of various types, with large fluctuations in composition and particle size due to different sources and varieties, as well as the unstable composition of mine products, and the stability of raw material composition is poor. The iron ore raw materials received at the port can be mixed to improve the stability of the raw material composition before the smelting process is carried out, which can effectively improve the technical and economic indicators of blast furnace ironmaking.

[0003] The existing coastal ports have a very large capacity to accept iron ore raw materials, but their functions are mainly the loading, unloading, storage and shipment of iron ore. In recent years, the ore mixing implemented in some ports has been limited to the use of simple forklifts to mix materials, or the use of two stackers to take out two different grades of iron ore from two stockpiles according to the designed hourly flow rate, and then transfer them to the third stacker with a belt conveyor, and mix the two raw materials on the third stockpile. This mixing method is called coarse mixing, which has few mixed ore types, poor mixing effect, and uneven mixture composition. If the factory does not perform pre-mixing treatment when using it, it will affect the stability of the sintered ore composition and cause a decline in blast furnace indicators.

[0004] Chinese patent CN 108946205 A discloses a port-based iron ore batching and mixing system, wherein the feeding system and the stacking system are arranged on the ground, and the batching system is arranged below the ground; the feeding system includes a belt conveyor feeding system and / or a car feeding system; the belt conveyor feeding system or the car feeding system is connected to the iron ore raw material storage system of the port; the batching system includes: a plurality of batching bins, which are located below the ground level; each batching bin is equipped with a feeder and an electronic belt scale; the feeder is arranged below the batching bin, and the feed port of the feeder is connected to the discharge port of the batching bin; the electronic belt scale is arranged below the discharge port of the feeder; the belt conveyor is arranged below the discharge end of all electronic belt scales; a PCL controller, the feeder and the electronic belt scale are electrically connected to the PCL controller respectively; the stacking system includes a stacker, and the receiving end of the stacker is connected to the discharge end of the conveying belt conveyor in the batching system. Due to the poor mobility of the system, the operating range is fixed after the production line is built, the operating range is small, and the work efficiency is low. It is impossible to accurately measure the amounts of a variety of different raw materials. When mixing the materials at the port, the batching accuracy is low and the mixing effect is poor, which cannot effectively improve the stability of the ore raw material composition.

[0005] In the prior art, the batching of port iron ore is processed by a simple mixing method, which results in uneven batching and affects the subsequent application process and products of the iron ore. Moreover, the existing batching systems are all fixed and can only be batched at fixed locations, which greatly reduces the applicability of the batching system. Utility Model Content

The batching vehicle of the utility model can reduce the external dimensions of the batching system body, and has a simple and reasonable structure, which can improve the maneuverability and applicability of the batching system. It can be widely used in the batching of port iron ore raw materials to improve the stability of the product.

[0039] Preferably, the running wheel can be a universal wheel or a tire, the running wheel is connected to the driving device, and the driving device is electrically connected to the control room.

[0040] The utility model provides a mobile mixing and batching vehicle. In the existing technology, a simple forklift is used for mixing, or two stackers are used to mix 2-3 kinds of raw materials. The mixed ore types are few, the mixing effect is poor, and the mixed material composition is uneven. If the factory does not perform mixing and pre-batch treatment when using it, it will affect the stability of the sintered ore composition and cause the blast furnace indicators to decline.

[0041] In view of the technical problem that the batching systems in the prior art are all fixed structures and cannot be moved, the utility model integrates the silo, weighing device and mixing device on a movable vehicle body. The bottom of the vehicle body is provided with running wheels, which can realize the free movement at the port to receive raw materials of different species, and after weighing the materials with the weighing device, the materials of different types (particle size, iron content, moisture content, etc.) are mixed, thereby improving the batching accuracy and the mixing effect.

[0042] In view of the problem in the prior art that the batching of port iron ore is merely simple mixing, resulting in poor uniformity of the material discharged from the batching system, which affects the subsequent sintering process of the iron ore, the utility model adopts reasonable arrangement of silos, mixing devices or cylindrical mixing and lifting devices and other components to achieve uniform mixing of iron minerals in a variety of different silos, so that the material discharged from the batching vehicle has good uniformity and can be directly used in the sintering process, thereby ensuring the quality of the iron products.

[0043] In the utility model, the device includes a vehicle body, a silo, a weighing device, and a conveying device. A movable running wheel is arranged at the bottom of the vehicle body (the running wheel has the function of changing direction and turning in addition to moving forward and backward, and the running wheel is a wheel or a universal wheel), and the vehicle body is driven to move by the running wheel so as to receive raw materials in different scenes. The silo is arranged above the vehicle body. Among them, along the direction of the material, the discharge port of the weighing device is connected to the conveying device. After accurate weighing and metering by the weighing device, the raw materials to be mixed are distributed and then sent to the conveying device. On the one hand, the design of the silo, the weighing device, and the conveying device on the vehicle body improves the maneuverability of the entire batching system. On the other hand, a weighing device is arranged between the silo and the bottom plate of the vehicle body. The raw materials are weighed and accurately measured by the weighing device, and then sent to the mixing device or the cylindrical mixing and lifting device for mixing through the conveying device to meet the precise batching and mixing of the materials.

[0044] In the utility model, a plurality of silos are arranged in the middle front part of the vehicle body along the direction of the materials (the number of silos can be increased according to actual needs), and a vibrator is arranged on the outer wall of the silo discharge port. The vibrator ensures smooth unloading of the materials. At the same time, a discharge control valve is arranged at the silo discharge port, and the opening of the discharge port is adjusted by the discharge control valve.

[0045] The multiple silos in the utility model are respectively arranged on both sides of the longitudinal axis of the vehicle body (the length direction of the vehicle body), that is, they include the left silo and the right silo, and the number of the left silo and the right silo is also multiple. The discharge ports of the left silo and the right silo are staggered. The discharge port of the left silo is biased toward the outside of the vehicle body, that is, biased toward the top of the weighing device, and the discharge port of the right silo is biased toward the inside of the vehicle body, that is, biased toward the location of the weighing device. This arrangement is convenient and frees up space for the arrangement of the weighing device. The height of the silo can be freely designed. If the silo is loaded by a forklift, the height of the silo is controlled within 3.2-3.5m, because the height is too low and the silo volume is too small. After the height exceeds 3.5m, it is difficult for conventional forklifts to deliver materials into the silo (the arm height of the general forklift in the port is 3.5m). If the silo is loaded by a heightening machine (stacker), the height of the silo is greater than 3.5m. The larger the silo height, the larger the capacity.

[0046] In the utility model, the weighing device is a belt scale, including weighing and short-distance conveying functions. From top to bottom, a silo, a belt scale, and a conveying device are arranged on the vehicle body in sequence. Among them, a belt scale is arranged below the discharge port of the plurality of left silos and right silos (wherein the belt scale has a length of more than 2.5m), and the conveying device is arranged on one side of the transverse axis of the vehicle body, for example, on the left side. The belt scales under the two adjacent silos on the left run in opposite directions. The belt scale under the right silo is arranged perpendicular to the running direction of the conveying device. After the materials in the right silo are discharged to the tail of the belt scale, they are transported to the conveying device through the belt scale, and the mass of the transported materials is weighed at the same time. Among them, along the direction of the materials, the conveying device in the front and middle part of the vehicle body is arranged horizontally, and a slope is formed between the conveying device at the rear of the vehicle body and the bottom plate of the vehicle body. In order to ensure that the materials on the conveying device belt will not slide down, the slope is 10°-60°, and a belt pressure wheel is arranged above the belt where the conveying device starts to climb to prevent the belt from being vacated. In the utility model, the belt scale can be fixed to the vehicle body through legs. The weighing accuracy of the belt scale can be ensured by the reasonable arrangement of the positions of the silo, conveyor and belt scale. When used for batching and mixing of port materials, the batching accuracy is high and the mixing effect is good, which can effectively improve the stability of the ore raw material composition.

[0047] In the utility model, the device also includes a support mechanism. Support mechanisms are provided on both sides of the transverse axis of the vehicle body. There are multiple support mechanisms (the number of support mechanisms can be increased according to actual needs). The left silo and the right silo are both fixed on the top of the vehicle body through the support mechanism, and the bottom of the support mechanism is a retractable jack. When the device is moved to the target position, the support bottom plate is placed on the ground for support through the telescopic rod of the jack, which can improve the stability of the device. When the loader is loading the silo during operation, the device can also maintain a high stability.

[0048] In the utility model, the device also includes a discharge hopper, a discharge port and a stacker. The discharge hopper is arranged at the discharge port of the conveying device. The mixing device is arranged at the rear of the vehicle body and is located on the opposite side of the conveying device at the rear of the vehicle body. The discharge port of the conveying device is connected to the feed port of the discharge hopper, and the discharge port of the discharge hopper is connected to the feed port of the mixing device. The discharge port is arranged at the rear of the vehicle body, and the vehicle body below the mixing device is provided with a notch as the discharge port. The discharge port is used for overlapping the stacker. The stacker extends through the discharge port to below the discharge port of the mixing device, and is used to receive the material mixed by the mixing device.

[0049] In the utility model, the device also includes a driving device and a control device. The driving device is a motor, and the travel wheels are driven by the driving device. Along the direction of the material, the control device is arranged on the top of the vehicle body, upstream of the left silo, and the control device is used to control the travel of the vehicle body and the operation of the equipment. The control device controls the movement of the device, adjusts the auxiliary support mechanism to make its supporting bottom plate fall to the ground, and the device is stable. The raw materials from the port are loaded into the silo by the loader (the same raw materials are loaded in the same silo), and the materials from each silo are unloaded to the belt scale, measured by the belt scale and then transferred to the conveying device. The raw materials in different silos are transferred to the mixing device through the conveying device, mixed evenly, and then unloaded to the stacker. After the stacker builds the material pile, the support mechanism is folded, and the driving device drives the travel wheels of the vehicle body to transfer the entire device to the next operation point.

[0050] In the utility model, the silo is used to hold the iron ore raw materials, and the multiple silos are used to hold the iron ore raw materials with different particle sizes, different iron grades or different moisture contents. A weighing device is provided below the discharge port of each silo, and the weighing device is used to weigh the iron ore raw materials discharged from different silos, so as to achieve the matching of different iron ore raw materials. The conveying device is used to convey the iron ore raw materials discharged from different silos and uniformly convey them to the next centralized component (mixing device or cylindrical mixing and lifting device). The silo, weighing device and conveying device are all independently arranged on the vehicle body.

[0051] In the present invention, the number of silos is 2-20, preferably 3-10, and more preferably 4-8, such as 4, 6, or 8.

[0052] In the first technical solution of the utility model, a combination of a belt conveyor and a mixing device is used to achieve the mixing of iron ore raw materials discharged from different silos. After the iron ore raw materials discharged from different silos are measured by their respective weighing devices, they are conveyed to the mixing device through a unified belt conveyor for mixing, and the materials after uniform mixing are uniformly discharged and enter the next process.

[0053] As a preferred method, since the mixed materials generally need to be transported by vehicles, and the vehicles have a certain height, the belt conveyor is designed to include a horizontal section and a lifting section. The horizontal section is used to receive the materials discharged from each silo, and the lifting section is used to lift the materials and transport them to the mixing device. The belt conveyor is composed of a belt and a driving roller.

[0054] In the second technical solution of the utility model, in order to solve the problem of uniform mixing of different iron ore raw materials, the utility model proposes a new cylindrical mixing and lifting device, which can simultaneously achieve the functions of lifting and mixing, and realize two different functions in one device. With a spiral ascending structure, after the iron ore raw materials discharged from different silos pass through the cylindrical mixing and lifting device, the materials are rolled in the cylindrical mixing and lifting device while being lifted, so as to achieve the effect of uniform mixing.

[0055] In the utility model, the cylindrical mixing and lifting device is a "Z"-shaped structure, including a feeding section, a mixing and lifting section and a discharging section, and the feeding section, the mixing and lifting section and the discharging section are all inclined structures. Among them, the feeding port of the feeding section is connected to the end of the conveying device. One end of the mixing and lifting section is connected to the feeding section, and the other end is connected to the discharging section. The feeding section connects the conveying device and the mixing and lifting section. The iron ore materials from different silos on the conveying device (belt conveyor) enter the cylindrical mixing and lifting device through the feeding section. The mixing and lifting section is provided with a spiral rising spiral blade. The bottom end of the spiral blade rolls up the material in the feeding section. The spiral blade rotates with the cylindrical shell, and the rolled material rises with the spiral blade; at the same time, the material rolls on the spiral blade, realizing the mixing of different iron ore raw materials. When reaching the top of the mixing and lifting section, since there is no spiral blade, the material automatically falls into the discharging section. After passing through the cylindrical mixing and lifting device, the different materials achieve the effect of uniform mixing, and at the same time, the height of the material is increased, which is convenient for transportation to the next process by vehicle. The feeding section, mixing and lifting section and discharging section are all inclined structures. The iron ore raw materials enter the inclined feeding section from the conveying device. The materials in the feeding section are lifted downward and upward to a certain height under the action of the spiral blades and then discharged through the discharging section of the inclined structure.

[0056] In the utility model, the feed section and the discharge section are fixed relative to the vehicle body, and the mixing and lifting section performs autorotational motion relative to the vehicle body. The feed section and the mixing and lifting section, as well as the mixing and lifting section and the discharge section are connected via bearings, thereby achieving seamless connection between the feed section and the mixing and lifting section, as well as between the mixing and lifting section and the discharge section, while ensuring the rotation of the mixing and lifting section. The mixing and lifting section includes a cylindrical shell, a spiral blade, and a driving roller. The spiral blade is arranged inside the cylindrical shell in a spiral ascending shape. The driving roller is arranged outside the cylindrical shell and drives the cylindrical shell to rotate. In addition, the cylindrical shell may be provided with one or more circles of gears, and the vehicle body may be provided with a driving gear, and the rotation of the cylindrical shell may be achieved by the cooperation of the driving gear and the gear on the cylindrical shell.

[0057] In the present invention, the feeding section, the mixing and lifting section and the discharging section can also be fixed structures (stationary) relative to the vehicle body. The mixing and lifting section includes a cylindrical shell, a drive shaft, and spiral blades. The drive shaft is arranged on the central axis of the cylindrical shell, and the spiral blades are arranged on the drive shaft. The drive shaft rotates under the action of the driving device, thereby driving the spiral blades to rotate, thereby lifting the material.

[0058] In the utility model, the cylindrical mixing and lifting device is arranged on the vehicle body, the driving roller is arranged on the vehicle body, the mixing and lifting section is supported by the driving roller, and the feeding section and the discharging section are directly fixed on the vehicle body.

[0059] In the utility model, the mobile mixing and batching vehicle also includes a dust suppression and moisture control device. The dust suppression and moisture control device plays two roles: one is to suppress dust when feeding into the silo, and the other is to adjust the moisture content of the material in the silo. Since dust is easily generated when feeding into the silo, the dust suppression effect is achieved by spraying water mist through the dust suppression and moisture control device. In addition, the material used in the sintering process has requirements for moisture content. The moisture content of the mixed material can be discharged through the first component and particle size detection device to detect the discharge port of the mixing device or the discharge port of the discharge section of the cylindrical mixing and lifting device, and the amount of water sprayed by the dust suppression and moisture control device is adjusted, thereby adjusting the moisture content of the mixed material.

[0060] In the utility model, the particle size of the mixed material discharged from the discharge port of the mixing device or the discharge port of the discharge section of the cylindrical mixing and lifting device is detected by the first component and the particle size detection device, the particle size of the material in each silo is detected by the second component and the particle size detection device, and the opening of the independent discharge control valve of each silo discharge port is adjusted to adjust the addition amount of materials with different particle sizes, thereby controlling the particle size of the material after uniform mixing.

[0061] In the present invention, the iron grade of the mixed material discharged from the discharge port of the mixing device or the discharge port of the discharge section of the cylindrical mixing and lifting device is detected by the first component and particle size detection device, the iron grade of the material in each silo is detected by the second component and particle size detection device, and the opening of the independent discharge control valve of each silo discharge port is used to adjust the addition amount of materials with different iron grades, thereby controlling the iron grade of the mixed material and ensuring the stability of the iron grade of the material delivered to the sintering process. Because for the sintering process, the higher the iron grade, the better, but the more stable the iron grade, the better. Through the first component and particle size detection device, the second component and particle size detection device, and the independent discharge control valve of each silo discharge port in the present invention, the stability of the iron grade of the material delivered to the sintering process can be ensured.

[0062] In the utility model, the material level detection device is used to monitor the height of the material level in the silo. The bulk material cleaning device is used to collect the materials scattered on the conveying device.

[0063] In the preferred embodiment of the utility model, when using the mobile mixing and batching vehicle of the utility model, the front walking observation device and the rear walking observation device are first opened, and the front and rear roads can be observed through the front walking observation device and the rear walking observation device, and then the driving of the walking wheel is started, and the steering and speed of the walking wheel are controlled according to the road conditions (which can be operated on site or remotely), and then the processing point is reached. The walking wheel is braked, and then the auxiliary support mechanism is turned on to fix the vehicle body. According to the feeding direction of the silo, the micro-mist dust suppression device on three sides of the silo is raised, and the micro-mist dust suppression device on one side is not raised for convenient feeding. When each silo starts to feed, the nozzle of the micro-mist dust suppression device is remotely controlled to open to suppress dust from flying out. When the silo is almost full, the high material level detection device sends a high material level signal to the control room, and the control room issues an instruction to slow down or suspend feeding; when the silo is almost empty, the low material level detection device sends a low material level signal to the control room, and the control room issues an instruction to speed up or start feeding. The belt scale under each silo transports various materials quantitatively to the conveying device below it. The conveying device transports various materials to a discharge hopper at a certain height. Various materials then enter the mixer below the discharge hopper for mixing. After mixing, the mixed materials enter the stacking machine for stacking. The composition and particle size detection device set below the mixer outlet detects the composition and particle size of the mixed materials. When the moisture content is high, the feedback signal is sent to the control room, and the control room starts the vibrator outside the silo to prevent the materials from sticking to the silo and causing blockage; when the moisture content is low, the feedback signal is sent to the control room, and the control room controls the water volume of the nozzle of the micro-fog dust suppression device so that the materials maintain a certain moisture content, which can increase the mixing effect; when the uniformity of the material composition is not good, such as the high content of a certain material, the feedback signal is sent to the control room, and the control room adjusts the belt scale under the corresponding silo to reduce the feeding amount, thus ensuring the uniformity of various materials. Alternatively, the conveying device transports various materials to the cylindrical mixing and lifting device, and various materials are mixed and lifted to a certain height in the cylindrical mixing and lifting device. The composition and particle size detection device set below the discharge port of the cylindrical mixing and lifting device detects the composition and particle size of the mixed material. When the water content is high, the feedback signal is sent to the control room, and the control room starts the vibrator outside the silo to prevent the material from sticking to the silo and causing blockage; when the water content is low, the feedback signal is sent to the control room, and the control room controls the water volume of the nozzle of the micro-fog dust suppression device to keep the material at a certain moisture content, which can increase the mixing effect; when the uniformity of the material composition is not good, such as the high content of a certain material, the feedback signal is sent to the control room, and the control room adjusts the belt scale under the corresponding silo to reduce the feeding amount, thus ensuring the uniformity of various materials.
