Description

Technical Field

[0001] This invention relates to the field of ore conveyor belts, and in particular to a pellet conveying device that prevents spillage. Background Technology

[0002] Pelletizing is a method for producing artificially formed bulk raw materials. It is a process that transforms powdered materials into those with physical properties and chemical composition that meet the requirements of subsequent processing. During pelletizing, the material undergoes changes in physical properties, such as density, porosity, shape, size, and mechanical strength, due to rolling into spheres and particle density. More importantly, it undergoes changes in chemical and physicochemical properties, such as chemical composition, reducibility, expansion, high-temperature reduction softening, low-temperature reduction softening, and melting properties, thereby improving the metallurgical properties of the material.

[0003] A typical pellet conveying device includes a base, a mounting plate, a power unit, and a conveying unit. The mounting plate is fixedly connected to the base, and the power unit and the conveying unit are fixed on the mounting plate. The power unit drives the conveying unit to operate, and the conveying unit transports the cooled pellets to the placement area.

[0004] However, in general factories, pellets are cooled using annular coolers. After the cooling process is complete, the characteristic of unloading material one truck at a time causes the flow rate on the finished product conveyor belt in the workshop to fluctuate regularly, sometimes large and sometimes small. At the same time, due to the space limitations of the storage area, in order to meet the demand for finished product pellets entering the warehouse, our department uses an inclined conveyor belt design for the finished product entering the warehouse. With the material amount on the belt changing regularly, the finished product conveyor belt also moves up and down regularly. In particular, when the flow rate on the finished product conveyor belt decreases, the belt bounces, causing the finished product pellets to be thrown away, resulting in a serious spillage of finished product pellets on site. Summary of the Invention

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0030] Reference Figures 1-7As shown, an anti-spillage pellet conveying device of the present invention includes a base 1; a support seat 11 and a support seat 2 are fixedly connected to the base 1; two support seats 11 and two support seats 2 are provided, and a conveying assembly 3 is fixedly connected to the support seats 2 and the support seat 11; the conveying assembly 3 includes a conveyor belt 31 and a fixing frame 32; the conveyor belt 31 is used to convey pellets; the conveyor belt 31 can be configured as a flat conveyor belt or an arc-shaped conveyor belt; the conveyor belt 31 includes a driving wheel, a driven wheel, and a conveyor... The conveyor belt 31 is composed of a drive pulley and a driven pulley. The fixed frame 32 includes a base plate 321. Vertical plates 322 are fixedly connected to both sides of the base plate 321. Two vertical plates 322 are provided. The two vertical plates 322 are used to fix the drive pulley and the driven pulley in the conveyor belt 31. Anti-splashing components 4 are inserted into the vertical plates 322. A mounting plate 33 is fixedly connected to the upper end of the vertical plates 322. A motor 34 is fixedly connected to the mounting plate 33. The motor 34 is used to drive the drive pulley of the conveyor belt 31 to rotate.

[0031] During operation, since the factory needs to place a large amount of pellets in a certain area, the pellets cannot be piled up in a disorderly manner. In order to maximize the amount of pellets in a limited area, the workers first move the conveyor to the pellet storage area and set the conveyor assembly 3 at a suitable height. Then, they start the motor 34 to make the conveyor belt 31 run. The produced pellets are cooled by an annular cooler. After the annular cooler is cooled, the pellets are unloaded one truck at a time and then transported to the storage area via the conveyor belt 31.

[0032] The support base 2 and the conveying assembly 3 are fixedly connected to a first cylinder 21; the first cylinder 21 is used to lift the conveying assembly 3.

[0033] During operation, in order to meet the requirement of placing more pellets, the conveyor belt 31 needs to be raised to a certain height during the conveying process, so that the pellets can be stacked higher and more pellets can be piled up in a limited area. Therefore, a first cylinder 21 is added between the support 2 and the conveying component 3. When the pellets slowly pile up to the discharge end of the conveyor belt 31, the first cylinder 21 is activated to raise the discharge end of the conveyor belt 31 to a certain height, so that the pellets can continue to pile up, improve the utilization rate of the stacking area, and enable the factory to place more pellets.

[0034] A plurality of rollers 311 are fixedly connected at equal intervals on the vertical plate 322; the rollers 311 are used to support the conveyor belt 31; a plurality of positioning holes 323 are opened at equal intervals on the upper end of the vertical plate 322; the positioning holes 323 are used to insert the anti-splashing component 4.

[0035] During operation, the conveyor belt will bend due to its own weight and the weight of the pellets. Over time, it will stretch and become longer, resulting in a decrease in the tension between the drive wheel and the driven wheel, which reduces the transmission efficiency and affects the conveying efficiency. Therefore, several sets of rollers 311 are set on the vertical plate 322 along the conveying direction of the conveyor belt to support the conveyor belt, reduce the tension on the conveyor belt, and increase the service life of the conveyor belt.

[0036] The anti-splashing component 4 includes a fixing frame 41; the fixing frame 41 is inserted into the positioning hole 323; a plurality of rotating shafts 42 are rotatably connected at equal intervals on the fixing frame 41; a baffle 43 is fixedly connected to each rotating shaft 42, and the baffle 43 maintains a moving distance from the conveyor belt;

[0037] During operation, the produced pellets are cooled using an annular cooler. After cooling, the pellets are unloaded onto conveyor belt 31 one truck at a time by transport vehicles. This causes the flow rate on the finished product conveyor belt in the workshop to fluctuate regularly, with periods of high and low flow. Due to space constraints, the finished product conveyor belt is designed to be inclined to meet the demand for finished product pellets entering the warehouse. As the flow rate of the pellets on the belt changes regularly, the finished product conveyor belt also moves up and down regularly. Especially when the flow rate on the finished product conveyor belt decreases, the belt bounces, causing the finished product pellets to be thrown around, resulting in significant spillage of finished product pellets on site. Therefore, a more... To minimize fluctuations in the flow rate of pellets during transport, a fixed frame 41 is installed above the vertical plate 322. A baffle 43 is fixedly connected to the fixed frame 41 via a rotating shaft 42. There is a certain gap between the baffle 43 and the conveyor belt. When the flow rate of pellets on the conveyor belt increases, that is, when the pile height of pellets on the conveyor belt is too high, the baffle 43 blocks the pellets, making the flow rate of pellets on the conveyor belt more uniform during transport, reducing the flow rate fluctuation of pellets on the conveyor belt during transport, reducing the vertical fluctuation of the conveyor belt, reducing the possibility of pellets being bounced away, reducing the loss of pellets, and also increasing the service life of the conveyor belt.

[0038] One end of the rotating shaft 42 is fixedly connected to a lever 421; the end of the lever 421 away from the rotating shaft 42 is rotatably connected to a connecting rod 422; the end of the connecting rod 422 facing the conveying direction is fixedly connected to a slider 423; the lever 421 is used for rotating the rotating shaft 42.

[0039] A second cylinder 44 is fixedly connected to the mounting plate 33; a slip ring 431 is fixedly connected to the telescopic shaft of the second cylinder 44; the slip ring 431 is slidably connected to the slider 423; the second cylinder 43 is used to move the connecting rod 422; the slip ring 431 is waist-shaped; the slider 423 can slide up and down inside the slip ring 431.

[0040] During normal operation, transport vehicles continuously deliver pellets to conveyor belt 31, resulting in a high flow rate of pellets on conveyor belt 31. This is because baffle 43 obstructs the transport of pellets. Therefore, it is necessary to increase the distance between the bottom of baffle 43 and the conveyor belt to increase the flow rate of pellets. This is achieved by activating the second cylinder 44, which shortens its telescopic shaft, pulling slip ring 431 in the direction of conveyor belt transport. Slip ring 431 pulls slider 423, causing connecting rod 422 to move. The lever 421 rotates under the action of connecting rod 422, driving shaft 42 to rotate baffle 43. This modification... The rotation angle of the baffle 43 can control the distance between the bottom of the baffle 43 and the conveyor belt. When the pellet conveying flow rate is consistently high, increasing the rotation angle of the baffle 43 increases the distance between the baffle 43 and the conveyor belt, allowing the pellets to be conveyed faster. When the pellet conveying flow rate is low, the rotation angle of the baffle 43 can be reduced or the baffle 43 can be kept perpendicular to the conveyor belt. This ensures that the baffle 43 can maintain a uniform conveying flow rate of the pellets regardless of whether the flow rate is high or low, minimizing the vertical fluctuation of the conveyor belt and preventing the pellets from being bounced off the conveyor belt. This also reduces the loss of pellets and minimizes environmental pollution.

[0041] A stop block 45 is rotatably connected to the rotating shaft 42; the stop block 45 is perpendicular to the direction of the baffle 43; two stop blocks 45 are provided, and the two stop blocks 45 are located on both sides of the baffle 43; the distance between the two stop blocks 45 is slightly less than the width of the conveyor belt, and the bottom of the baffle 45 is slightly higher than the upper surface of the conveyor belt; the stop block 45 is used to block the scattering of the pellets and to keep the pellets inside the conveyor belt;

[0042] During operation, as the ore pellets are transported on the conveyor belt, whether it is a flat or curved conveyor belt, the ore pellets will roll off the sides of the conveyor belt. In addition, a small amount of ore pellets will be bounced off the sides of the conveyor belt due to the up-and-down movement of the conveyor belt. This not only causes loss of ore pellets but also causes great pollution to the working environment. Therefore, baffles 45 are installed on both sides of the baffle 43. Since the baffles 45 are inside the conveyor belt, the ore pellets are confined within the conveyor belt during transport, preventing them from rolling off the sides of the conveyor belt. In addition, the small amount of ore pellets that are bounced off the sides of the conveyor belt due to the up-and-down movement of the conveyor belt are also stopped by the baffles 45, preventing the ore pellets from spilling onto the ground.

[0043] Fixed columns 5 are fixedly connected to the four corners of the lower surface of the base 1; the fixed columns 5 are hollow structures; through holes 51 and sliding grooves 52 are provided on both sides of the fixed columns 5; the through holes 51 are located above the sliding grooves 52; during operation, the fixed columns 5 can support the entire conveying device, and the fixed columns 5 can move, so that the entire conveying device can be flexibly adjusted, thereby improving the utilization rate of the storage area and facilitating the work of the operators;

[0044] An eccentric wheel 6 is provided inside the fixed column 5; the end of the eccentric wheel 6 with a longer eccentric distance is set as a plane 62; the shaft 42 of the eccentric wheel 6 passes through the through hole 51 and is rotatably connected to the through hole 51; a rocker arm 61 is fixedly connected to the shaft 42 of the eccentric wheel 6.

[0045] The fixed column 5 has a movable block 7 inside; the movable block 7 is a hollow structure; a limiting column 71 is fixedly connected to the movable block 7; the limiting column 71 is slidably connected to the slide groove 52; the outer surface of the movable block 7 is in contact with the inner surface of the fixed column 5; a roller 72 is rotatably connected inside the movable block 7; the roller 72 is used for moving the conveying device of the present invention.

[0046] During operation, when it is necessary to transport pellets to the storage area, the conveying device needs to be moved to the storage area. At this time, the rocker arm 61 on the eccentric wheel 6 is rotated, causing the eccentric wheel 6 to rotate. The rotation of the eccentric wheel 6 causes the plane 62 on the eccentric wheel 6 to abut against the upper surface of the moving block 7, fixing the eccentric wheel 6. As the eccentric wheel 6 rotates, the distance between the edge of the eccentric wheel 6 and the center of rotation gradually increases. Therefore, the eccentric wheel 6 gradually pushes the moving block 7 out of the fixed column 5. The roller 72 on the moving block 7 is pushed out to contact the ground, causing the conveying device to detach from the ground. Thus, the conveying device can move under the action of the roller 72, allowing the conveying device to be flexibly adjusted and moved arbitrarily within the storage area, transporting the pellets to any location within the storage area, improving the utilization rate of the storage area. When the conveying device moves to the designated position, the rocker arm 61 on the eccentric wheel 6 is rotated again, causing the eccentric wheel 6 to rotate and the moving block 7 to return to the fixed column 5, making the entire conveying device stable under the support of the fixed column 5, facilitating the transport of pellets.

[0047] The vertical plate 322 is fixedly connected to a scraper 8 at one end of the conveyor assembly 3 where the material is falling; the scraper 8 is used to scrape off the material on the surface of the conveyor belt 31 and change the direction of the falling pellets.

[0048] During operation, the conveyor assembly 3 continuously transports pellets, including during rainy days. This can cause the pellets to stick to the conveyor belt after encountering rainwater, preventing them from being transported and causing them to be thrown off the conveyor belt, resulting in environmental pollution and waste of finished pellets. Therefore, a scraper 8 is installed at the discharge end of the conveyor belt. The scraper 8 contacts the conveyor belt and guides the falling direction of the pellets. By changing the tilt angle of the scraper 8, the falling direction of the pellets can be changed, making it easier to stack the pellets. At the same time, the scraper 8 can scrape off the pellets stuck to the conveyor belt, cleaning the conveyor belt, increasing its service life, and reducing pellet waste.

[0049] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
