Description

Technical Field

[0001] The invention relates to the technical field of steel slag recycling waste-free treatment, and in particular to a steel slag recycling waste-free treatment system. Background Art

[0002] Steel slag is a byproduct of the steelmaking process. On average, about 0.15 to 0.2 tons of steel slag is generated for every ton of steel produced. Steel slag contains a large amount of metallic iron particles and oxides of calcium, iron, silicon, magnesium and a small amount of aluminum, manganese, phosphorus, etc. The total iron content in steel slag is about 15 to 30%. At present, steel slag is processed in the hot melt state at the front end and then processed in the secondary process at the later stage. Common uses are mainly as follows: (1) Used as a metallurgical solvent to replace limestone in smelting and also recover a large amount of metallic iron; (2) Used in cement production, steel slag can be used as an iron correction material mixed with other raw materials to produce high-strength cement; (3) Used as a concrete admixture to prepare new building materials such as blocks, hollow bricks, and concrete products. It is also used as landfill material in projects such as roadbed, backfill, dam construction, and land reclamation; (4) Used as a soil conditioner and agricultural fertilizer, steel slag can adjust soil pH, improve soil physical and chemical properties, increase soil fertility, and improve crop yield and quality. Due to the complex composition and large fluctuation of steel slag, the utilization rate of steel slag has always remained at a relatively low level. At present, it has not been well utilized in a comprehensive way, with an annual utilization rate of only about 20% to 30%, and basically all of it is used for low added value. The utilization rate of steel slag is low, the treatment is difficult, and a large amount of accumulation not only occupies land but also pollutes the environment. If it is not handled and utilized in a comprehensive way in a timely manner, it will inevitably have an adverse impact on the healthy and sustainable development of society.

[0003] The existing steel slag treatment technology route is generally to crush the steel slag first and then grind it, but its annual consumption is limited. At the same time, the high iron content of steel slag determines that the grinding equipment is worn out during the production process, and its grinding efficiency is low, the iron recovery rate is low, and the economic efficiency is poor. Therefore, the low-cost and high-value resource utilization of steel slag is particularly important.

[0004] The disclosure discloses a steel slag comprehensive utilization system and method with the publication number CN118122461A, which comprises a primary crushing and grading iron selection system and a secondary iron selection and powder making system; the primary crushing and grading iron selection system comprises a column mill, a first magnetic separator and an air classifier; the column mill crushes the steel slag, the first magnetic separator selects iron from the crushed steel slag, the air classifier classifies the steel slag after iron selection, and the large-particle steel slag with a particle size greater than 4.750 mm is returned for crushing again, and the remaining steel slag is collected and enters the secondary iron selection and powder making system; the secondary iron selection and powder making system comprises a steel slag vertical mill and a dynamic powder selector; the steel slag vertical mill dries and grinds the collected steel slag to obtain a specific surface area greater than 450m2.

[0005] The above technical solution cannot fully classify and recycle the steel slag waste, and cannot effectively crush the steel slag waste, which affects the subsequent recycling effect, so it needs to be improved. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a steel slag recycling waste-free treatment system.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] The crushing assembly is provided with a power mechanism, the upper end of the crushing assembly is penetrated by a feeding hopper, the power mechanism is provided with a first crushing roller and a second crushing roller, one end of the first crushing roller is fixed with a first pushing rod, the upper end of the first pushing rod is rotatably connected with the second pushing rod, a round tube fixing part is fixed in the feed hopper, a conveying plate part is commonly fixed between the round tube fixing part and the feed hopper, a feeding port part is provided on the round tube fixing part, the feeding port part and the conveying plate part correspond to each other, a lifting rod part is slidably installed in the round tube fixing part, the lifting rod part extends into the round tube fixing part, the lower end of the lifting rod part is rotatably sleeved with a pressing block part, a rotating mechanism is provided in the lifting rod part, the rotating mechanism and the pressing block part are connected, a stamping mechanism is provided on the lifting rod part, a top block part is provided on the stamping mechanism, and the top block part is located at the lower end of the pressing block part; a feeding mechanism is provided on the round tube fixing part, and the feeding mechanism is connected with the feeding port part and the pressing block part.

[0010] Compared with the prior art, the present application can fully crush the steel slag waste, and can effectively screen and magnetically separate the crushed steel slag, and can effectively ensure the environmental protection during the operation, protect the staff, and can effectively control the relative movement of the pressing block and the top block to impact and damage the steel slag, and can also achieve the crushing of the steel slag by the rotation of the pressing block, so as to facilitate the subsequent precise control of the rotation of the first crushing roller and the second crushing roller, and adapt to different specifications of steel slag, so as to facilitate the passage of steel slag, avoid damage to the equipment, and ensure the crushing effect.

[0011] Preferably, the feeding mechanism includes an oblique opening on the round tube fixing member, the oblique opening is located at the upper end of the feed port member, a sliding frame is penetrated in the oblique opening, a connecting groove is opened on one side of the sliding frame, a fixed shaft member is penetrated in the connecting groove, one end of the fixed shaft member is rotatably connected to a side wall at one end in the oblique opening, a shaft sleeve is sleeved on the fixed shaft member, a support rod is penetrated on the shaft sleeve and the fixed shaft member, two ends of the support rod are respectively fixed on the opposite side walls in the connecting groove, a second resistance spring member is sleeved on the support rod member, and two ends of the second resistance spring member are respectively fixed in the connecting groove and the shaft kit, an inverted Z-shaped through-hole is provided on one side of the sliding frame, an elastic telescopic frame member is installed in the inverted Z-shaped through-hole, an inverted Z-shaped frame is installed on the elastic telescopic frame member, the upper and lower ends of the inverted Z-shaped frame respectively pass through the upper and lower ends of the sliding frame, a connecting frame is sleeved on the sliding frame, a partition member is fixed at the lower end of the connecting frame, the partition member is located on one side of the feed port member, the lower end of the inverted Z-shaped frame is penetrated and arranged on the partition member, a notch member is provided on one side of the upper end of the pressing block member, one end of the sliding frame extends into the notch member, and the sliding frame extends to the lower side of one end of the notch member and is inclined.

[0012] Furthermore, during actual production and preparation, because the slag can squeeze the partition member, the slag cannot pass through the feed port member. When the pressing block member rises, the bottom of the notch member will resist the sliding frame so that the second resistance spring member is squeezed, which can enable the sliding frame to stably enter the notch member, thereby facilitating the separation of the pressing block member and the top block member, and enabling the crushed slag to fall. When the pressing block member and the top block member move relative to each other, the pressing block member will squeeze the upper end of the sliding frame, which can cause the inverted Z-shaped frame on the sliding frame to be squeezed, so that the inverted Z-shaped frame is inserted into the partition member, thereby fixing the sliding frame and the partition member. When the sliding frame is squeezed and rotated by the pressing block member, it can drive the partition member to rotate. At the same time, the side of the partition member away from the feed port member is arranged in a triangle, which is convenient for quickly separating the slag and realizing rotation. At the same time, when closed, it can push the slag into between the pressing block member and the top block member, thereby facilitating extrusion and crushing.

[0014] Furthermore, as the lifting rod member is lifted and lowered, the lead screw can cause the pressing block member to rotate under the action of the lead screw nut, thereby achieving a crushing operation on the steel slag.

[0015] Preferably, the stamping mechanism includes a linkage gear rotatably connected to one side of the feed hopper, and both sides of the linkage gear are meshed with spur gears.

[0019] Furthermore, when the second crushing roller is moved under force, the mounting frame will move toward the direction close to the motor assembly, so that the distance between the sleeve and the slide rod is stretched, and the angle between the sleeve and the bottom becomes smaller, so that the push rod pushes the moving block to move away from the motor assembly, causing the first inclined rod to pull the rocker arm to deflect, and the sliding member can descend to adapt to the deflection of the rocker arm, giving the mounting frame a reset force, so as to quickly push the moving plate and the second crushing roller to reset through the first elastic resistance assembly, fully contact the waste material, and crush it.

[0020] Preferably, the power mechanism includes a motor assembly respectively installed on one side of the crushing assembly, two first crushing rollers respectively penetrate the crushing assembly and extend to both sides of the crushing assembly, a synchronous wheel is fixed on one end of the first crushing roller and the output shaft of the motor assembly, and a synchronous belt is installed between the two synchronous wheels; a tensioning mechanism is provided on the second crushing roller, and the tensioning mechanism is connected to the motor assembly.

When slag that cannot be crushed falls, it will squeeze the second crushing roller, so that the second crushing roller transfers the pressure to the movable plate, which in turn compresses the sliding rod, making it easier for the slag to fall. At the same time, the second elastic resistance component can also effectively adapt to the external force transmitted from the mounting frame, so that the second crushing roller can fully move, making it easier for the harder slag to fall.

[0028] Preferably, the feed hopper is located between the first crushing roller and the second crushing roller; baffle members are fixed on opposite side walls in the pulverizing assembly, and the first crushing roller and the second crushing roller are respectively located on both sides of the lower end of the baffle member.
