Description

Technical Field

[0001] The present invention relates to the technical field of steel slag recycling, and particularly to a production system for iron-containing material briquettes. Background Art

[0002] During the iron and steel production process, various wastes are generated, such as coke, steel slag, dust removal ash, etc. Considering that these resources will pollute the environment, it is necessary to treat and reuse these wastes to improve the utilization efficiency of resources.

[0003] In related technologies, the treatment of coke, steel slag, and dust removal ash mostly involves transporting them to the required manufacturers for recycling. Coke can be recovered through a collection system, and after being pretreated by screening, crushing, etc., it can be reused in processes such as blast furnace ironmaking. Steel slag contains various valuable components such as iron, CaO, Si, MnO, etc., and the steel slag and tail slag can be separated through processes such as crushing and magnetic separation. The slag steel can be directly returned to the steelmaking process, while the tail slag can be used as raw materials in the building materials industry, such as for the production of steel slag cement, steel slag bricks, etc. Dust removal ash is rich in metal elements such as iron and zinc, and there are various recovery treatment methods, including injection methods, sintering methods, pelletizing methods, rotary hearth furnace methods, direct reduction methods in rotary kilns, etc.

[0004] However, dust is easily generated during the transportation and storage of coke, steel slag, and dust removal ash. Especially in open-air storage yards or open transportation, the diffusion of dust will exacerbate air pollution, and high-efficiency dust removal facilities (such as bag dust removal, spray systems) need to be equipped. Separately treating various wastes is relatively troublesome, and transportation and storage need to be separated, which is not convenient for centralized recovery and treatment. Summary of the Invention

[0005] The purpose of the present invention is to provide a production system for iron-containing material briquettes to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A production system for iron-containing material briquettes, including a storage hopper, the storage hopper is used to store each kind of raw material separately, a loosening mechanism is installed on the storage hopper, the loosening mechanism keeps the raw materials in a scattered state, prevents the raw materials from caking, ensures the smooth discharge of the raw materials, and improves the proportioning accuracy of the raw materials;

[0007] A material flow control valve, the material flow control valve is connected to the storage hopper, the material flow control valve controls the amount of raw materials discharged from the storage hopper, and can both control the discharge speed of the raw materials and the proportioning amount of the raw materials, ensuring that each finished product is relatively uniform;

[0008] A weighing belt, the weighing belt is located below the material flow control valve, the weighing belt transports and weighs each kind of raw material, and controls the proportioning amount of the raw materials;

[0009] A mixer, which is located below the end of a weighing belt. The mixer receives the raw materials transported by the weighing belt and stirs them evenly to generate a mixed material, ensuring that all kinds of raw materials are evenly mixed.

[0010] A transport belt, which is located below the mixer. The transport belt receives and conveys the mixed material discharged by the mixer.

[0011] An extruder, which is located below the end of the transport belt. The extruder receives the mixed material so that the mixed material is extruded into a specified shape, which is not only convenient for transportation but also saves transportation space, and has a high comprehensive utilization efficiency of resources.

[0012] Furthermore, the loosening mechanism is a vibrator. The vibrator causes the raw materials to vibrate and flow into the feed flow control valve. The vibrator loosens the materials, thus realizing uniform feeding, avoiding blockage and sticking in the bin, and also solving the problem of difficult discharging from the bin.

[0013] Furthermore, a level sensor is provided above the storage hopper. The level sensor detects the remaining amount of raw materials in the storage hopper. When the raw materials are insufficient, it can send an alarm to replenish the raw materials in time to ensure that the production of finished products does not lack the corresponding raw materials.

[0014] Furthermore, two scraper devices are provided and installed on the weighing belt and the transport belt. The scraper devices remove the residual raw materials on the weighing belt and the transport belt, avoiding the unsmooth operation or failure of the belt caused by the accumulation of raw materials on the belt, reducing friction and resistance, and making the operation more stable and efficient.

[0015] Furthermore, a storage hopper is provided at the discharge port of the extruder, which can store the finished products and facilitate loading the finished products onto the vehicle.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) Storing different raw materials in the storage hopper facilitates the centralized treatment of various raw materials, reduces dust emission and raw material waste. The storage hopper can reduce dust diffusion and avoid environmental pollution.

[0018] (2) The vibrator as the loosening mechanism vibrates the raw materials to prevent caking, ensures uniform feeding, avoids blockage or sticking problems, improves the accuracy of raw material ratio. The storage hopper is equipped with a level sensor to detect the remaining amount of raw materials in real time and automatically alarm when the materials are insufficient, ensuring the continuity of production and the stability of raw material ratio.

[0019] (3) The star-shaped discharge valve accurately controls the discharge speed and quantity of raw materials, ensuring that the ratio of the mixed material in each batch is consistent and the specifications of the finished products are unified. The extruder presses the mixed material into a regular shape, saving transportation space and improving the comprehensive utilization rate of resources; the storage hopper directly stores the finished products, simplifying the loading process.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment:

[0025] Please refer to Figure 1-2 , the present invention provides a technical solution: a production system for iron-containing material briquettes, including a storage hopper 1, the storage hopper 1 is used to store each kind of raw material separately, four storage hoppers 1 are provided, which store coke, steel slag, binder, and dust removal ash respectively. A loosening mechanism is installed on the storage hopper 1, and the loosening mechanism keeps the raw materials in a dispersed state, ensuring that coke, steel slag, binder, and dust removal ash are not easily caked and can smoothly fall into the material flow control valve;

[0026] The material flow control valve, the material flow control valve is connected to the storage hopper 1, and the material flow control valve controls the amount of raw materials discharged from the storage hopper 1 and the discharge speed of the raw materials from the storage hopper 1, so as to ensure that the amount of raw materials discharged each time is within the allowable error range, thereby improving the quality and consistency of the final product;

[0027] The weighing belt 2, the weighing belt 2 is located below the material flow control valve, the weighing belt 2 transports and weighs each kind of raw material, controls the raw material ratio, and monitors and accurately records the weight of each kind of raw material in real time, automatically and continuously weighing and proportioning the raw materials;

[0028] The mixer 3, the mixer 3 is located below the end of the weighing belt 2, the mixer 3 receives the raw materials transported by the weighing belt 2 and stirs them evenly. It can immediately receive the raw materials accurately proportioned by the weighing belt 2 without additional transfer steps, thereby shortening the time from proportioning to mixing of the raw materials, improving the overall production efficiency, fully and evenly stirring the raw materials, ensuring the uniform distribution of each kind of raw material in the mixed material, and avoiding the situation of component stratification or local concentration being too high / low, thereby ensuring the quality stability of the finished product;

[0029] The conveying belt 4 is located below the mixer 3. The conveying belt 4 picks up and conveys the mixed material discharged from the mixer 3, and can continuously convey the uniformly mixed raw materials to the extruder 5 to realize automatic transportation of the raw materials.

[0030] The extruder 5 is located below the end of the conveying belt 4. The extruder 5 receives the mixed material so that the mixed material is extruded into a specified shape, and compresses the mixed raw materials into finished products.

[0031] In this embodiment, the storage hopper 1 is composed of a cylinder and a conical pipe. The material flow control valve is connected to the conical pipe, which is beneficial to the smooth flow of the raw materials under the action of gravity. The raw materials flow towards the material flow control valve, reducing the problem of raw materials sticking to the wall.

[0032] In this embodiment, the loosening mechanism is a vibrator. The vibrator causes the raw materials to vibrate and flow into the material flow control valve. By generating vibration, the vibrator can break the adhesion and friction between the raw materials, changing the raw materials from a stored state to a flowing state, improving the conveying efficiency of the raw materials and the continuity of the flow.

[0033] In this embodiment, a level sensor is provided above the storage hopper 1. The level sensor detects the remaining amount of raw materials in the storage hopper 1. When the remaining amount of raw materials is insufficient, the sensor will send a signal to remind the operator to supplement the raw materials in time, thus avoiding production interruption.

[0034] In this embodiment, the material flow control valve is a star-shaped discharge valve. The star-shaped discharge valve continuously discharges the raw materials in the storage hopper 1 quantitatively. The rotor blades of the star-shaped discharge valve will evenly scrape the raw materials in the storage hopper 1 and convey them continuously and stably to the weighing belt 2.

[0035] In this embodiment, the extruder 5 is a briquetting machine or a block-making machine, which can extrude the uniformly mixed raw materials into spheres or blocks.

[0036] In this embodiment, two scraper devices are installed on the weighing belt 2 and the conveying belt 4. The scraper devices remove the residual raw materials on the weighing belt 2 and the conveying belt 4, avoiding the problem of inaccurate weighing caused by raw material residue, and helping to maintain the accuracy of weighing.

[0037] In this embodiment, a storage hopper 6 is provided at the discharge port of the extruder 5 to pick up the finished products, which is convenient for loading the finished products onto the vehicle.

[0038] Specifically, during use, put coke, steel slag, binder, and dedusting ash into the four storage hoppers 1, start the weighing belt 2. When the weighing belt 2 starts, observe the batching weighing belt 2 and adjust the weighing belt 2 to be directly below the discharge opening of the storage hopper 1, and ensure that there is no obvious bump during the belt conveying process, and it runs smoothly and evenly at a constant speed.

[0039] After checking that the sealing of the discharge opening of the mixer 3 is good, start the mixer 3. Observe that the stirring blades of the mixer 3 rotate stably and uniformly, and there is no abnormal noise or vibration in the mixer 3, indicating that the mixer 3 is operating well.

[0040] Open the rotary valves of the coke, steel slag, binder, and dedusting ash storage hoppers 1 in sequence. Start the vibrator to ensure smooth material discharge. The rotary valve controls the rotation speed and adjusts the discharge material flow to an appropriate size, allowing the raw materials to be transported into the mixer 3 through the weighing belt 2. Observe the mixing situation in the mixer 3. When the raw materials in the mixing blender pass the midline, close the rotary valves in sequence. After all the raw materials on the weighing belt 2 have entered the blender, stop the operation of the weighing belt 2.

[0041] Start the conveyor belt 4. After the conveyor belt 4 runs stably, open the discharge opening of the mixer 3 and send the mixed material into the extruder 5. After the extruder 5 completes the pressing of the current round of mixed material, the finished product falls into the storage hopper 6, and this pressing block is completed.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
