Description

Technical Field

[0001] This utility model relates to the field of ore sintering technology, and in particular to a sampling device for sintered ore fed into a furnace. Background Technology

[0002] In the ironmaking system of integrated iron and steel enterprises, sintered ore, as one of the main raw materials for blast furnaces, is generally transported into the blast furnace raw material bin by belt conveyor after being produced in the sintering plant. A vibrating screen is arranged directly below the bin, and the sintered ore flows evenly onto the screen surface through the feeder below the bin. It is necessary to sample and test the particle size of the screened sintered ore.

[0003] A search revealed a prior art device for sampling sintered ore fed into a blast furnace (Publication No.: CN217717112U), comprising a dust collection box located on a workbench, a vibrating screen extending into the dust collection box at one end, and a weighing tank located below the vibrating screen and with its top inside the dust collection box; characterized in that it further comprises a material-collecting trolley; an opening is provided at the bottom of one side of the dust collection box for the material-collecting trolley to pass through; two tracks are provided inside the dust collection box for the material-collecting trolley to travel on; the material-collecting trolley adopts a pushcart structure, including a mother car and a daughter car; a groove is provided inside the mother car, so the daughter car is located in the groove, and the two together constitute the car body; and one side of the daughter car is hinged to the mother car; when the material-collecting trolley moves from the opening into the dust collection box, it is located below the discharge port of the vibrating screen.

[0004] In existing technologies, samples are transported and collected by setting up detachable mother cars and daughter cars. One side of the daughter car is hinged to the mother car, which means that the mother car can only rotate on one side to discharge materials. For actual production applications, there is a need for material discharge on both sides. This also means that the existing method of single-sided rotation of the daughter car has drawbacks and room for optimization.

[0005] Therefore, we propose a sampling device for sintered ore entering the furnace. Utility Model Content

[0006] The present invention mainly solves the technical problem that the above-mentioned trolley can only be rotated on one side, which limits its flexibility, and provides a sampling device for sintered ore entering the furnace.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a sampling device for sintered ore fed into a furnace, comprising:

[0008] A mother car and a daughter car for loading, the daughter car being detachably connected to the mother car;

[0009] A connecting assembly is provided between the mother car and the daughter car for assembling and disassembling the daughter car. The connecting assembly includes a mounting base, a sliding clamp, and a fixed clamp. The mounting base and the fixed clamp are both fixedly installed on the mother car. The sliding clamp is slidably connected to the mounting base. The mounting base and the sliding clamp together form a cylinder. A rotating shaft is fixedly provided on the top of the daughter car. The rotating shaft can rotate inside the cylinder.

[0010] In a preferred embodiment of this utility model, four ear plates are fixedly installed on the top of the mother car, and one ear plate is fixedly installed on one side of each ear plate. Two ear plates form a group, and two groups of ear plates are symmetrically distributed on the top of the daughter car.

[0011] In a preferred embodiment of this utility model, both the sliding clamp and the fixed clamp are arc-shaped plates, with a fixed clamp provided at each end of the sliding clamp, and the inner diameters of the sliding clamp and the fixed clamp are equal.

[0012] In a preferred embodiment of the present invention, the connecting component further includes a guide block, which is fixedly connected to a sliding clamp, and the sliding clamp is slidably connected to the mounting base via the guide block.

[0013] In a preferred embodiment of this utility model, the top of the mounting base is provided with a groove for adapting to the guide block. The guide block is slidably disposed in the groove. The guide block and the sliding clamp are integrally formed. The guide block is an arc-shaped block and is located on the outer circumferential surface of the sliding clamp. The guide block and the groove cooperate with each other.

[0014] In a preferred embodiment of this utility model, the connecting assembly further includes a positioning hole and a pin. The positioning hole is provided at the end of the guide block, and the pin is inserted into the mounting base. The pin can be inserted into the positioning hole to lock the sliding clamp.

[0015] In a preferred embodiment of this utility model, the end of the guide block is provided with a plurality of positioning holes arranged in a circular array. The positioning holes are round holes that penetrate the guide block. The pin is adapted to the positioning holes. The side wall of the mounting base is provided with a socket for the pin, and the pin is inserted into the socket.

[0016] This utility model provides a sampling device for sintered ore entering a furnace. It has the following beneficial effects:

[0017] 1. This furnace sinter sampling device uses four sets of connecting components on the top of the mother car. Each rotating shaft is rotatably mounted inside a cylinder formed by a sliding clamp and a fixed clamp. When the subcar needs to be tilted to one side of the mother car to discharge the collected material, the subcar is tilted, which drives the ear plate and rotating shaft to move. The rotating shaft rotates around the corresponding cylinder to discharge the material. The subcar can be tilted to one side of the mother car as needed, making the material discharge more flexible. At the same time, the four sets of connecting components support and limit the four rotating shafts, which can ensure the stability of the subcar and the mother car after assembly.

[0018] 2. This furnace sinter sampling device, by setting a guide block, pushes a sliding clamp, which in turn drives the guide block to slide in a groove at the top of the mounting base. The concave surface of the fixed clamp faces upward, while the concave surface of the sliding clamp faces downward. Thus, the cylinder formed by the sliding clamp and the fixed clamp can wrap around the rotating shaft to ensure that the rotating shaft will not fall off. When the subcar is tilted, the sliding clamps on both sides of the same side of the mother car can be tilted so that the concave surfaces of the sliding clamp and the two fixed clamps face upward at the same time, thereby releasing the restriction on one side of the subcar. The side of the subcar that is unlocked is lifted up, allowing it to tilt and discharge material. Of course, the locks on both sides of the subcar can also be released at the same time to disassemble and use the subcar. The disassembly and assembly of the subcar is more convenient and convenient for actual production use.

[0019] 3. In this furnace sinter sampling device, as the sliding clamp rotates, the positioning hole and insertion hole at the end of the guide block align. By pushing the pin, the pin is inserted into the positioning hole to lock the sliding clamp. The cylindrical structure formed by the sliding clamp and the fixed clamp is more stable, and the stability of the trolley and the mother car after assembly is guaranteed.

[0026] A sampling device for sintered ore entering the furnace, such as Figure 1 and Figure 2 As shown, it includes:

[0027] The mother car 10 and the daughter car 11 for loading are detachably connected to the mother car 10. Rollers are rotatably connected to the bottom of both the mother car 10 and the daughter car 11 to support their movement.

[0028] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a connecting assembly is set between the mother car 10 and the daughter car 11 for assembling and disassembling the daughter car 11. The connecting assembly includes a mounting base 20, a sliding clamp 21, and a fixed clamp 22. The mounting base 20 and the fixed clamp 22 are both fixedly installed on the mother car 10. The sliding clamp 21 is slidably connected to the mounting base 20. The mounting base 20 and the sliding clamp 21 together form a cylinder. A rotating shaft 13 is fixedly installed on the top of the daughter car 11. The rotating shaft 13 can rotate inside the cylinder. Four ear plates 12 are fixedly installed on the top of the mother car 10. One ear plate 12 is fixedly installed on one side of each ear plate 12. Two ear plates 12 form a group. Two groups of ear plates 12 are symmetrically distributed on the top of the daughter car 11. The sliding clamp 21 and the fixed clamp 22 are both arc-shaped plates. A fixed clamp 22 is set at each end of the sliding clamp 21. The inner diameters of the sliding clamp 21 and the fixed clamp 22 are equal.

[0029] In this design, four sets of connecting components are installed on the top of the mother car 10. Each rotating shaft 13 is rotatably mounted inside the cylinder formed by the sliding clamp 21 and the fixed clamp 22. When the daughter car 11 needs to be flipped to one side of the mother car 10 to discharge the collected material, the daughter car 11 is flipped, which drives the ear plate 12 and the rotating shaft 13 to move. The rotating shaft 13 rotates around the corresponding cylinder to discharge the material. The daughter car 11 can be flipped to one side of the mother car 10 as needed, making the material discharge more flexible. At the same time, the four sets of connecting components support and limit the four rotating shafts 13, which can ensure the stability of the daughter car 11 after it is assembled with the mother car 10.

[0030] like Figure 4 As shown, the connecting assembly also includes a guide block 23, which is fixedly connected to the sliding clamp 21. The sliding clamp 21 is slidably connected to the mounting base 20 through the guide block 23. The top of the mounting base 20 is provided with a groove that adapts to the guide block 23. The guide block 23 is slidably disposed in the groove. The guide block 23 and the sliding clamp 21 are integrally formed. The guide block 23 is an arc-shaped block. The guide block 23 is located on the outer circumferential surface of the sliding clamp 21. The guide block 23 and the groove cooperate with each other.

[0031] By setting the guide block 23, the sliding clamp 21 is pushed, and the sliding clamp 21 drives the guide block 23 to slide in the groove at the top of the mounting base 20. The concave surface of the fixed clamp 22 faces upward, while the concave surface of the sliding clamp 21 faces downward. Thus, the cylinder formed by the sliding clamp 21 and the fixed clamp 22 can wrap around the rotating shaft 13 to ensure that the rotating shaft 13 will not fall off. When flipping the subcar 11, the sliding clamps 21 on both sides of the mother car 10 can be flipped so that the concave surfaces of the sliding clamp 21 and the two fixed clamps 22 face upward at the same time, thereby releasing the restriction on one side of the subcar 11. The side of the subcar 11 that is unlocked is lifted up so that it flips to achieve material discharge. Of course, the locks on both sides of the subcar 11 can also be released at the same time to remove the subcar 11 for use. The ease of disassembling and assembling the subcar 11 is higher, which is convenient for actual production use.

[0032] like Figure 3 and Figure 4 As shown, the connecting assembly also includes a positioning hole 24 and a pin 25. The end of the guide block 23 has a positioning hole 24, and the pin 25 is inserted into the mounting base 20. The pin 25 can be inserted into the positioning hole 24 to lock the sliding clamp 21. Several positioning holes 24 are distributed in a circular array at the end of the guide block 23. The positioning holes 24 are round holes that penetrate the guide block 23. The pin 25 is adapted to the positioning hole 24. The side wall of the mounting base 20 has a hole adapted to the pin 25, and the pin 25 is inserted into the hole.

[0033] As a supplement to the above solution, in order to ensure the locking and limiting effect of the sliding clamp 21 on the rotating shaft 13 after it is flipped, when the sliding clamp 21 is flipped, the positioning hole 24 and the insertion hole at the end of the guide block 23 are aligned. By pushing the pin 25, the pin 25 is inserted into the positioning hole 24 to lock the sliding clamp 21. The cylindrical structure formed by the sliding clamp 21 and the fixed clamp 22 is more stable, and the stability of the daughter car 11 and the mother car 10 after assembly is guaranteed.

[0034] The working principle of this utility model is as follows: Four sets of connecting components are installed on the top of the mother car 10. Each rotating shaft 13 is rotatably mounted inside the cylinder formed by the sliding clamp 21 and the fixed clamp 22. When the child car 11 needs to be tilted to one side of the mother car 10 to discharge collected material, the child car 11 is tilted, causing the ear plate 12 and the rotating shaft 13 to move. The rotating shaft 13 rotates around the corresponding cylinder to discharge the material. The child car 11 can be tilted to one side of the mother car 10 as needed. By setting a guide block 23, the sliding clamp 21 is pushed. The sliding clamp 21 drives the guide block 23 to slide in the groove on the top of the mounting base 20. The concave surface of the fixed clamp 22 faces upward, while the concave surface of the sliding clamp 21 faces downward. Thus, the cylinder formed by the sliding clamp 21 and the fixed clamp 22 can enclose the rotating shaft. 13. Ensure that the rotating shaft 13 will not fall off. When flipping the subcarriage 11, the sliding clamps 21 on both sides of the mother car 10 can be flipped so that the concave surfaces of the sliding clamps 21 and the two fixed clamps 22 face upwards at the same time, thereby releasing the restriction on one side of the subcarriage 11. The side of the subcarriage 11 that is unlocked is lifted up so that it flips to achieve material discharge. Of course, the locks on both sides of the subcarriage 11 can also be released at the same time to remove the subcarriage 11 for use. When the sliding clamps 21 are flipped, the positioning hole 24 and the insertion hole at the end of the guide block 23 are aligned. By pushing the pin 25, the pin 25 is inserted into the positioning hole 24 to lock the sliding clamps 21. The cylindrical structure formed by the sliding clamps 21 and the fixed clamps 22 is more stable, and the stability of the subcarriage 11 after assembly with the mother car 10 is guaranteed.

[0035] In sintering plants, whether it is a large blast furnace with belt conveyor or a small blast furnace with car conveyor, the screening system under the ore bin is generally the same: from top to bottom, it consists of a feeder, a vibrating screen, a weighing tank, and a dust collection box at the junction of the vibrating screen and the weighing tank. The workbench (or second-floor platform) serves as a working layer, making more rational use of space. The dust collection box is fixed on the workbench, and the weighing tank is located below the workbench with its top inside the dust collection box. This includes the dust collection box on the workbench, the vibrating screen extending into the dust collection box, and the weighing tank located below the vibrating screen with its top inside the dust collection box. In this scheme, the mother car 10 is used in conjunction with the track. The mother car 10 moves to the bottom of the vibrating screen to receive the material and achieve sampling.
