Description

Technical Field

[0001] This utility model relates to the technical field of smelting furnace charging vehicles, specifically a smelting furnace charging vehicle hopper. Background Technology

[0002] A feeding cart is needed during the charging process inside a smelting furnace. A feeding cart is a transport vehicle used to add materials. It is widely used in factories, mines and other workplaces that require the addition of large amounts of materials. It can travel on the ground or on rails to transport materials from one location to another. Feeding carts are usually electrically or hydraulically driven and have advantages such as large load capacity, smooth operation and simple operation. The feeding cart includes multiple structures, including a feeding hopper structure.

[0003] Existing charging vehicles connect a connecting arm to a driving vehicle, with a hopper attached to the connecting arm. The driver then drives the vehicle to extend the hopper into the furnace opening, and then pushes the material in the hopper into the smelting furnace. However, when pushing out the material, firstly, the stored material is of varying sizes, and secondly, the material is discharged instantly and falls into the furnace, forming a pile. During smelting, the material is prone to agglomeration, affecting the stability of the electric furnace and the smelting effect. Therefore, we propose a charging vehicle hopper for smelting furnaces to solve this defect of the existing technology. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hopper for a smelting furnace charging car.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a charging hopper for a smelting furnace, comprising a rectangular hopper frame with an opening extending through the top and bottom, a connecting column on the right side of the hopper frame, an isolation sealing plate that slides through the right side of the hopper frame, the isolation sealing plate being fitted and sealed against the inner wall of the hopper frame, and a pushing member on the hopper frame for pushing the isolation sealing plate to move;

[0006] Multiple feeding hoppers are provided between the left and right side walls of the inner cavity of the hopper frame. The frontmost feeding hopper is sealed to the front inner wall of the hopper frame, and the rearmost feeding hopper is sealed to the rear inner wall of the hopper frame. Multiple crushing rollers rotate between the left and right side walls of the inner cavity of the hopper frame. Each pair of crushing rollers forms a group, and there are multiple groups, equal in number to the number of feeding hoppers. The two crushing rollers in each group are symmetrically distributed back and forth based on the lower opening of the feeding hopper as the center, and there is a gap between the crushing rollers.

[0007] The hopper frame is equipped with a drive assembly that drives two of the crushing rollers in each set of crushing rollers to rotate counterclockwise relative to each other.

[0008] Using the above technical solution, the hopper frame is installed on the driving vehicle via a connecting column. The driver then drives the vehicle to extend the hopper frame into the furnace opening. Subsequently, the set pushing component moves the isolation sealing plate, opening the hopper frame. The material in the hopper frame falls into the feeding hopper and is discharged between each set of crushing rollers. The set driving component drives each set of crushing rollers to rotate counterclockwise to crush and discharge the material, improving the uniformity of the discharged material particles and the uniform dispersion effect of the material efficiency, avoiding the accumulation and clumping of the discharged material, and ensuring the stability of the electric furnace and the smelting effect of the material.

[0009] As a preferred embodiment of this utility model, the front and rear side walls of the inner cavity of the hopper frame are provided with guide rail grooves for the sliding of the isolation sealing plate.

[0010] By adopting the above technical solution, the guide rail groove ensures the stability of the movement of the isolation sealing plate.

[0011] As a preferred embodiment of this utility model, the pushing member includes a heat insulation seat disposed outside the connecting column, and a hydraulic push rod is disposed outside the heat insulation seat, with the push rod of the hydraulic push rod connected to the isolation sealing plate.

[0012] Using the above technical solution, the heat insulation seat isolates heat, and the hydraulic push rod pushes the isolation sealing plate to move, thereby achieving the isolation sealing plate to block and seal the hopper frame, and the movement of the isolation sealing plate to open and discharge the material.

[0013] As a preferred embodiment of this utility model, the driving assembly includes a plurality of support frames disposed on the right side of the hopper frame, the number of support frames being equal to the number of the hoppers. Each support frame is located on the side of each group of crushing rollers. A gear located on the right side of the hopper frame is provided concentrically on the right side of the crushing rollers. The corresponding gears on each group of crushing rollers mesh with each other. A drive motor is provided on the support frame, and the output shaft of each drive motor is concentrically connected to one of the corresponding gears on each group of crushing rollers.

[0014] Using the above technical solution, the drive motor on the support frame drives the gear to rotate. By utilizing the meshing between the gears, each set of crushing rollers on the gear rotates counterclockwise, thereby crushing and feeding the material.

[0015] As a preferred embodiment of this utility model, a heat insulation cover is provided on the right side of the hopper frame, located outside the drive motor, support frame and gear.

[0016] Using the above technical solution, the heat insulation cover isolates heat.

[0017] As a preferred technical solution of this utility model, the sealing cover at the opening above the hopper frame is provided with a switch cover, and the heat insulation seat is provided with a hydraulic push rod two, the push rod of the hydraulic push rod two being connected to the switch cover.

[0018] Using the above technical solution, the hydraulic push rod 2 pushes the switch cover to move, which facilitates the opening and closing of the hopper frame opening, making it convenient for loading and unloading.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0020] 1. The charging hopper of this smelting furnace is installed on the driving vehicle via a connecting column. The driver extends the hopper frame to the furnace opening by driving the vehicle. Then, the set pusher moves the isolation sealing plate, opening the hopper frame. The material in the hopper frame falls into the discharge hopper and is discharged between each set of crushing rollers. The set drive component drives each set of crushing rollers to rotate counterclockwise to crush and discharge the material, improving the uniformity of the discharged material particles and the uniform dispersion effect of the material efficiency, avoiding the accumulation and agglomeration of the discharged material, ensuring the stability of the electric furnace and the smelting effect of the material.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1 to 5 In this embodiment, a smelting furnace charging hopper includes a rectangular hopper frame 1 with a through opening at the top and bottom. The hopper frame 1 is made of a high-strength, wear-resistant, and high-temperature resistant metal material, such as stainless steel, to ensure that it can withstand the weight, friction, and high temperature of the material during long-term use and is not easily damaged. A connecting column 2 is provided on the right side of the hopper frame 1. The connecting column 2 is firmly fixed to the hopper frame 1 by welding and is used to install the hopper on the driving vehicle.

[0030] An isolation sealing plate 3 is slidably provided inside the hopper frame 1, extending to the outside of the right side of the hopper frame 1. The isolation sealing plate 3 is fitted and sealed to the inner wall of the hopper frame 1 to prevent material leakage. The space above the hopper frame 1 formed by the isolation sealing plate 3 and the hopper frame 1 is used to store materials. The function of the isolation sealing plate 3 is to isolate the hopper frame 1 during transportation to prevent materials from accidentally spilling. When it is necessary to unload materials, the opening of the hopper frame 1 is opened by moving the isolation sealing plate 3.

[0031] The front and rear side walls of the inner cavity of the hopper frame 1 are provided with guide rail grooves for the sliding of the isolation sealing plate 3, which reduces the friction when the isolation sealing plate 3 slides and ensures that the isolation sealing plate 3 does not fall off when sliding in the hopper frame 1, thus ensuring the stability of the movement of the isolation sealing plate 3.

[0032] The hopper frame 1 is equipped with a pusher that moves the isolation sealing plate 3. This pusher includes a heat insulation seat 11 bolted to the outside of the connecting column 2. The heat insulation seat 11 is made of a material with good heat insulation properties, such as ceramic fiberboard, to prevent heat transfer from the hopper frame 1 to external equipment. A hydraulic push rod 12 is bolted to the outside of the heat insulation seat 11, and its push rod is connected to the isolation sealing plate 3. A section of heat insulation rod is fixed between the push rod and the heat insulation seat 11. The heat insulation rod can be a glass fiber rod or a ceramic fiber rod. When it is necessary to open the hopper frame 1, the hydraulic push rod 12 operates, pushing the isolation sealing plate 3 to move to the right along the guide rail groove, thus opening the hopper frame 1. When it is necessary to close the opening, the hydraulic push rod 12 operates in the opposite direction, pulling the isolation sealing plate 3 to the left to achieve a seal.

[0033] Multiple feeding hoppers 4 are fixed between the left and right side walls of the inner cavity of the hopper frame 1. The frontmost feeding hopper 4 is sealed to the front inner wall of the hopper frame 1, and the rearmost feeding hopper 4 is sealed to the rear inner wall of the hopper frame 1. The upper opening of the feeding hopper 4 is large and the lower opening is small. Its function is to guide the material in the hopper frame 1 to the crushing roller 5.

[0034] Multiple crushing rollers 5 rotate between the left and right side walls of the inner cavity of the hopper frame 1. Each pair of crushing rollers 5 forms a group, and there are multiple groups. The number of groups is equal to the number of feeding hoppers 4. In this application, the number of crushing rollers 5 is no less than 4 groups. The two crushing rollers 5 in each group are symmetrically distributed back and forth based on the lower opening of the feeding hopper 4. There is a gap between the crushing rollers 5. The size of the gap can be adjusted according to the characteristics of the material, generally 5-20mm. The crushing rollers 5 are made of high hardness and wear-resistant alloy steel, and the surface is quenched to improve their wear resistance and service life.

[0035] The hopper frame 1 is equipped with a drive assembly that drives two crushing rollers 5 in each set of crushing rollers 5 to rotate counterclockwise relative to each other. It includes multiple support frames 7 fixed to the right side of the hopper frame 1, the number of support frames 7 being equal to the number of hoppers 4. Each support frame 7 is located on the side of each set of crushing rollers 5 and is fixed to the hopper frame 1 by bolts. A gear 6 located outside the right side of the hopper frame 1 is fixed concentrically on the right side of the crushing roller 5. The corresponding gears 6 on each set of crushing rollers 5 mesh with each other. A drive motor 8 is fixed to the right side of the support frame 7. The drive motor 8 is a high-performance AC motor with high power and stable operation. The output shaft of each drive motor 8 is concentrically connected and fixed to the corresponding left gear 6 on each set of crushing rollers 5, and connected by a coupling to ensure the accuracy of transmission. When the drive motor 8 is working, it drives the gear 6 connected to it to rotate. Due to the meshing relationship between the gears 6, each set of crushing rollers 5 rotates counterclockwise relative to each other, crushing the material falling between the crushing rollers 5.

[0036] A heat insulation cover 11 is fixed on the right side surface of the hopper frame 1, located outside the drive motor 8, support frame 7 and gear 6. The heat insulation cover 11 is made of multiple layers of heat insulation materials, such as fiberglass cotton and aluminum foil, to effectively isolate heat, protect the drive motor 8 and other equipment from high temperature, and extend the service life of the equipment.

[0037] The opening above the hopper frame 1 is sealed with a switch cover 9, which is made of the same metal material as the hopper frame 1 to ensure a sealing effect.

[0038] A hydraulic push rod 2 10 is fixed to the upper end of the heat insulation seat 11. The hydraulic push rod 2 10 is fixed to the heat insulation seat 11 by bolts. Its push rod part is connected and fixed to the switch cover 9. A section of heat insulation rod is fixed between the push rod and the heat insulation seat 11. The heat insulation rod can be a glass fiber rod or a ceramic fiber rod. When it is necessary to feed materials, the hydraulic push rod 2 10 works to push the switch cover 9 to move upward and open the opening above the hopper frame 1 to facilitate feeding. After feeding is completed, the hydraulic push rod 2 10 works in the opposite direction to pull the switch cover 9 to move downward and close the opening to facilitate transfer and unloading.

[0039] The charging hopper of this smelting furnace is equipped with an electrical control system.

[0040] The electrical control system mainly consists of a controller and a drive motor control module. The controller adopts a programmable logic controller (PLC), which has the characteristics of flexible programming and high reliability. The controller controls the start, stop and speed of the drive motor 8 to achieve precise control of the crushing roller 5. At the same time, the controller also controls and coordinates the actions of hydraulic push rod 12 and hydraulic push rod 20 to achieve automated control of the entire hopper.

[0041] Usage steps,

[0042] Feeding: The driver drives the vehicle to transport the hopper of the feeding truck to the material storage area. The driver controls the hydraulic push rod 210 through the electrical control system to push the switch cover 9 to move upward, opening the opening above the hopper frame 1 and pouring the material into the hopper frame 1. After feeding is completed, the driver controls the hydraulic push rod 210 to work in the opposite direction, pulling the switch cover 9 downward to close the opening.

[0043] Transportation: The driver drives the vehicle to transport the hopper of the charging truck to the furnace mouth of the smelting furnace.

[0044] Feeding: When the hopper frame 1 reaches the furnace opening, the hydraulic push rod 12 is controlled by the electrical control system to move the isolation sealing plate 3 to the right, opening the opening of the hopper frame 1. The material in the hopper frame 1 falls into the feeding hopper 4 and then is discharged between each set of crushing rollers 5. At the same time, the controller controls the drive motor 8 to start, driving each set of crushing rollers 5 to rotate counterclockwise relative to each other, crushing and feeding the material, so that the material falls evenly into the smelting furnace.

[0045] Reset: After the material is fed, control the hydraulic push rod 12 to work in reverse, pull the isolation sealing plate 3 to move to the left, close the opening of the hopper frame 1, and complete one feeding process.

[0046] Through the detailed description of the above structural design, positional connection relationship, structural scheme principle, usage steps, structural materials and system control, the charging hopper of this smelting furnace can effectively solve the problems existing in the prior art and improve smelting efficiency and effect.

[0047] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
