Technical Field

[0001] This utility model belongs to the technical field of material feeding devices, specifically relating to an adjustable steel slag hot-quenching material feeding device. Background Technology

[0002] Hot curing of steel slag is a steel slag treatment process. It involves crushing high-temperature steel slag with high-pressure water spray and utilizing residual heat to promote slag-iron separation. The process includes: high-temperature liquid steel slag treatment: 1600℃ liquid steel slag is crushed to a particle size of 10mm by high-pressure water spray, and simultaneously rapidly cooled to 800℃; slag pit stage: steel slag cooled to 320℃ is poured into a slag pit and further cooled to 320℃; hot curing operation: under a pressure of 0.2-0.4MPa, the steel slag is cured in a hot curing tank for 8-12 hours, reducing the metallic iron content to below 2% through chemical reactions. This process is currently the mainstream method for steel slag treatment in China, and the treated steel slag can meet application standards such as road paving.

[0003] The hot slag loading device is a key piece of equipment in the steel slag treatment process. It is mainly used to pour hot steel slag into the hot slag loading device and perform preliminary loosening treatment. This device is the starting equipment of the hot slag loading treatment process and directly affects the efficiency and safety of subsequent treatment.

[0004] Because steel slag particles vary in size and have high moisture content, traditional fixed discharge ports are prone to clogging, affecting continuous production. Furthermore, the non-adjustable discharge port leads to unstable discharge speed, which can easily result in material accumulation or cavities. To address this, we propose an adjustable steel slag hot-quenching discharge device. Utility Model Content

[0005] To address the problems mentioned in the background art, such as the uneven size and high moisture content of steel slag particles, which easily lead to blockages in traditional fixed discharge ports, affecting continuous production, and the inability to adjust the discharge port resulting in unstable discharge speed and material accumulation or cavities, this utility model provides an adjustable steel slag hot-pressing discharge device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable steel slag hot quenching feeding device, comprising a base, a hot quenching tank and an adjusting plate, wherein the hot quenching tank is fixedly installed on the base, a discharge hopper is fixedly installed at the bottom of the hot quenching tank, and adjusting plates are slidably installed on both sides below the discharge hopper, a guide platform is fixedly installed at the upper end of the adjusting plate, and a hydraulic telescopic rod is connected to the outside of the guide platform;

[0007] The hot jar has pusher plates slidably installed on both sides inside. A conveyor block is fixed above the pusher plate. A threaded screw is installed inside the conveyor block. A conveyor motor is fixed to one end of the threaded screw.

[0008] As a preferred embodiment of the adjustable steel slag hot curing feeding device of this utility model, the hot curing tank is provided with feeding ports on both sides above, and the front end of the hot curing tank is equipped with a sealed tank door via a hinge.

[0009] As a preferred embodiment of the adjustable steel slag hot quenching feeding device of this utility model, an L-shaped support frame is welded on both sides below the hot quenching tank, and the hydraulic telescopic rod is fixed on the support frame.

[0010] In a preferred embodiment of the adjustable steel slag hot-pressing feeding device of this utility model, the hydraulic telescopic rod is horizontally arranged, and the telescopic end of the hydraulic telescopic rod is connected to the guide platform.

[0011] In a preferred embodiment of the adjustable steel slag hot quenching feeding device of this utility model, the adjusting plate is horizontally slidably disposed below the discharge hopper, and the guide platform is inclined.

[0012] In a preferred embodiment of the adjustable steel slag hot quenching feeding device of this utility model, the pusher plate is symmetrically arranged on both sides inside the hot quenching tank and can move horizontally towards the middle.

[0013] In a preferred embodiment of the adjustable hot slag feeding device of this utility model, the conveying block is threadedly engaged with the threaded screw, and the conveying motor drives the conveying block to move through the threaded screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In this application, the adjusting plate is driven to move horizontally by a hydraulic telescopic rod, which can flexibly adjust the opening size of the discharge hopper to adapt to steel slag with different particle sizes and moisture content. The adjustable discharge port allows operators to accurately control the flow rate and falling speed of the material according to actual production needs, realizing the stability and uniformity of the discharge process. The design of the guide platform plays a good guiding role for the falling steel slag, further preventing it from accumulating near the outlet. This prevents the traditional fixed discharge port from being prone to blockage, affecting continuous production, and the problem that the discharge port is not adjustable, which is prone to material accumulation or cavity phenomenon.

Embodiment 1

[0023] like Figures 1-5 As shown;

[0024] An adjustable steel slag hot curing feeding device includes a base 1, a hot curing tank 2, and an adjusting plate 6. The hot curing tank 2 is fixedly installed on the base 1. A discharge hopper 5 is fixedly installed at the bottom of the hot curing tank 2. Adjusting plates 6 are slidably installed on both sides below the discharge hopper 5. A guide platform 7 is fixed at the upper end of the adjusting plate 6. A hydraulic telescopic rod 8 is connected to the outside of the guide platform 7. Pushing plates 10 are slidably installed on both sides inside the hot curing tank 2. A conveying block 11 is fixed above the pushing plate 10. A threaded screw 12 passes through the conveying block 11. A conveying motor 13 is fixed at one end of the threaded screw 12.

[0025] In this implementation scheme: The hydraulic telescopic rod 8 drives the adjusting plate 6 to move horizontally, which can flexibly adjust the opening size of the discharge hopper 5 to adapt to steel slag with different particle sizes and moisture content. The adjustable discharge port allows the operator to accurately control the flow rate and falling speed of the material according to the actual production needs, realizing the stability and uniformity of the discharge process. The design of the guide platform 7 plays a good guiding role for the falling steel slag, further preventing it from accumulating near the outlet.

[0026] In an optional embodiment, the hot braising pot 2 is provided with inlets 3 on both sides above, and a sealed pot door 4 is installed at the front end of the hot braising pot 2 via a hinge.

[0027] In this implementation plan: the feed inlet 3 facilitates feeding, and the sealed tank door 4 is installed with a hinge, which allows for flexible opening and closing, ensuring the sealing of the hot quenching tank 2 and providing the necessary conditions for the high-pressure hot quenching process of steel slag. At the same time, it facilitates subsequent maintenance and repair.

[0028] In an optional embodiment, L-shaped support frames 9 are welded to both sides of the lower part of the hot pot 2, and the hydraulic telescopic rod 8 is fixed to the support frame 9.

[0029] In this implementation scheme: an L-shaped support frame 9 is used and welded to the hot jar 2, providing an extremely stable and reliable mounting base for the hydraulic telescopic rod 8.

[0030] In an optional embodiment, the hydraulic telescopic rod 8 is horizontally positioned, and the telescopic end of the hydraulic telescopic rod 8 is connected to the guide table 7.

[0031] In this implementation scheme: the hydraulic telescopic rod 8 is set horizontally, and its thrust acts directly on the guide platform 7, driving the adjustment plate 6 to perform precise horizontal linear movement, which can realize stepless and linear adjustment of the size of the discharge port opening, thereby accurately controlling the material flow rate.

[0032] In an optional embodiment, the adjusting plate 6 is horizontally slidably disposed below the discharge hopper 5, and the guide platform 7 is inclined.

[0033] In this implementation plan: the horizontal sliding of the adjusting plate 6 enables flexible adjustment of the discharge port size, fundamentally solving the problem of easy blockage of fixed discharge ports. The inclined guide platform 7 plays a good role in guiding and accelerating the falling material, effectively preventing the material from accumulating or getting stuck at the edge of the discharge port, and ensuring smooth material discharge.

[0034] In an optional embodiment, the pusher plate 10 is symmetrically arranged on both sides inside the hot jar 2 and can move horizontally towards the center.

[0035] In this implementation scheme, the symmetrically arranged double pusher plates 10 move towards each other, which can efficiently and without dead angle push the residual material at the bottom of the hot simmering tank 2, especially the corners on both sides, towards the central discharge hopper 5 area, greatly reducing the material residue in the tank, significantly improving the discharge efficiency and tank cleaning effect, and avoiding the risk of resource waste and manual cleaning.

[0036] In an optional embodiment, the conveyor block 11 is threadedly engaged with the threaded screw 12, and the conveyor motor 13 drives the conveyor block 11 to move through the threaded screw 12.

[0037] In this implementation scheme, the use of a screw drive allows the pusher plate 10 to reliably stop at any position, providing high thrust, high control precision, smooth and reliable operation, and a high degree of automation.

[0038] Working principle:

[0039] The feeding and hot curing process involves pouring molten or red-hot steel slag at 300-800°C from the steelmaking furnace into the hot curing tank 2 via a tanker truck. Feeding is completed through the top feed inlet 3, and then the sealing tank door 4 is closed, making the tank a sealed, high-pressure container for hot curing. Atomized water is sprayed evenly and controllably into the sealed tank. Upon contact with water, the high-temperature steel slag rapidly generates a large amount of high-temperature saturated steam. This steam accumulates in the sealed tank, generating pressure. The high-temperature steam penetrates the micro-cracks in the steel slag, causing it to expand and contract, thus breaking it apart and making large pieces of steel slag loose. After several hours of water spraying and pressure curing, water spraying is stopped, allowing the pressure and temperature inside the tank to naturally decrease to a safe range.

[0040] After the discharge port is adjusted and the process is completed, wait for the temperature and pressure inside the tank to drop to normal before discharging. The discharge hopper 5 is located at the bottom of the hot simmering tank 2, and its opening size can be adjusted by the adjusting plate 6. Start the hydraulic telescopic rod 8, and the hydraulic telescopic rod 8 pushes the adjusting plate 6 to move horizontally, thereby changing the opening degree of the discharge port and controlling the falling speed and flow rate of the material. The guide platform 7 moves together with the adjusting plate 6 to guide the falling steel slag and prevent the material from accumulating near the discharge port, ensuring smooth discharge.

[0041] The material pusher assists in unloading. The conveyor motor 13 is started, and the conveyor motor 13 drives the threaded screw 12 to rotate, causing the conveyor block 11 to drive the pusher plate 10 to move horizontally towards the center, pushing the steel slag remaining in the tank to the center position of the discharge hopper 5. This is especially suitable for thorough cleaning when the amount of material is small. The size of the discharge port is controlled by the hydraulic system, and the motor drives the pusher mechanism to realize the automation and adjustability of the discharge process, thereby improving the discharge efficiency and thoroughness.

[0042] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
