Description

Technical Field

[0001] The present invention relates to the technical field of slag treatment devices, and in particular to a method and equipment for treating copper mine waste slag. Background Art

[0002] Slag is a byproduct of the blast furnace ironmaking process. During this process, iron oxide is reduced to metallic iron at high temperatures. Impurities such as silica and alumina in the iron ore react with lime and other materials to form a molten material primarily composed of silicates and aluminosilicates. This molten material is quenched into a loose, porous granular material known as slag. Copper ore is a common type of slag. Slag processing requires grinding to facilitate the subsequent recycling of residual minerals within the slag, such as in the production of concrete, cement, and other materials.

[0003] The patent document with publication number CN221245454U discloses a ball mill for processing raw materials for producing slag composite powder, including a baffle on the outer shell, a chute on the outer shell, and a slide on the surface of the chute, a limiting groove on the box body, and a limiting plate on the surface of the limiting groove, a round hole on the pull plate, and a handle on the pull plate; the beneficial effects are: the slide plate realizes the material collection of raw materials, avoids the tilting of the ball mill for material collection, saves time and effort, the application of the chute ensures the overall stability of the structure, and facilitates the disassembly and assembly of the slide plate, the pull plate realizes the function of screening the raw materials, and the control handle repeatedly pulls the pull plate, thereby improving the efficiency of screening the raw materials, the application of the limiting plate and the limiting groove ensures the stability of the structure, and the application of the baffle ensures that the pull plate can fully collect the raw materials.

[0004] In actual use, the above scheme has the problem that the two sides of the shell are sealed by circular plates, so the device can only grind a certain batch of slag at a time. After the batch of slag is ground, the machine needs to be stopped for unloading, which is cumbersome and inefficient. In addition, the inner wall of the shell is smooth, which causes the steel balls inside to be unable to reach a height suitable for impacting the slag as the shell rotates during the rotating ball mill, and thus the slag cannot be effectively crushed. Summary of the Invention

[0005] The invention discloses a method and equipment for treating copper mine waste slag, aiming to solve the technical problems of low processing efficiency and unsatisfactory crushing effect in existing slag treatment devices.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: Copper mine waste slag processing equipment includes a base plate, a connecting seat and a collection frame are respectively embedded on the upper surface of the base plate, an inclined mounting cylinder is rotatably connected to the surface of the connecting seat through a collar, a feed port is embedded at the left end of the inclined mounting cylinder, a discharge port is provided at the right end of the inclined mounting cylinder, a coarse-mesh plate is provided on the inner wall of the discharge port, a screening mechanism is provided inside the collection frame, and a drying mechanism is provided on the upper surface of the base plate adjacent to the feed port; The inner wall of the oblique mounting cylinder is provided with a resistance-increasing convex strip, the left surface of the connecting seat is embedded with a first motor, the output shaft of the first motor is fixedly connected to a transmission gear, and the surface of the oblique mounting cylinder is fixedly installed with a driven gear disk that meshes with the transmission gear.

[0007] In a preferred solution, the number of the resistance-increasing convex strips is several, and the several resistance-increasing convex strips are arranged in a circular array on the inner wall of the oblique installation cylinder.

[0008] By setting the resistance-increasing convex strips, the steel ball can move to a certain height and fall down as the oblique installation cylinder rotates.

[0009] In a preferred solution, the screening mechanism includes a filter plate arranged inside the collection frame, and the interior of the collection frame is slidably connected to a collection box via a slide rail.

[0010] By setting the filter plate, the slag after ball milling can be screened for subsequent recycling.

[0011] In a preferred solution, transmission grooves are provided on the inner front wall and the inner rear wall of the collection frame, and a second motor is fixedly installed on the left surface of the collection frame. The output shaft of the second motor extends to the interior of the front transmission groove and is fixedly connected to a reciprocating screw. The surface of the reciprocating screw is threadedly connected to a threaded block. The inner walls on both sides of the rear transmission groove are fixedly connected to guide sliding rods, and the surface of the guide sliding rods is slidably connected to a guide sliding block. The opposite surfaces of the threaded block and the guide sliding block are respectively fixedly connected to the front and back of the filter plate.

[0012] By setting the second motor and the reciprocating screw, the filter plate can be driven to move back and forth left and right, so that it reaches a shaking state.

[0013] In a preferred solution, the right side surface of the collecting frame is rotatably connected to a limit block for limiting the collecting box via a rotating seat.

[0014] In a preferred embodiment, the drying mechanism includes a feed barrel fixedly mounted above the base plate by a support frame, the inner bottom wall of the feed barrel is embedded with a feed pipe extending to the inside of the feed port, an annular air cavity is provided inside the shell of the feed barrel, and an air outlet hole penetrating into the inside of the feed barrel is provided on the inner wall of the annular air cavity, a hot air blower is fixedly mounted on the upper surface of the base plate, and the air outlet end of the hot air blower is connected to the inside of the annular air cavity.

[0015] By setting up the hot air blower and the annular air cavity, the water vapor mixed with the slag can be removed to facilitate the subsequent ball milling work.

[0016] In a preferred solution, there are a plurality of air outlet holes, which are arranged in a circular array on the inner wall of the annular air cavity.

[0017] In a preferred solution, a threaded opening is provided at the right end of the oblique installation cylinder, an external thread is provided on the surface of the discharge port, and the discharge port is threadedly connected to the inner wall of the threaded opening via the external thread.

[0018] By setting the threaded opening and the external thread, the discharge port can be removed from the inclined installation cylinder, which provides convenience for taking out the steel balls therein.

[0019] The method for treating copper mine waste slag comprises the following steps: Step 1: Movement Mechanism: The first rubber hinge on the outside of the mounting base is linked to a hydraulic telescopic rod, driving the adjustment frame and its rubber roller to adaptively move along the intestinal wall. A traction rope and an adjustment handle adjust the mounting base's forward and backward position. The hydraulic telescopic rod automatically expands and contracts according to the intestinal diameter, ensuring the rubber roller maintains constant contact with the intestinal wall, ensuring smooth movement of the tool within the intestine. Step 2: Telescopic buffer mechanism: It is composed of a fixed limit column, a spring and a first sleeve. The spring provides elastic buffering to absorb the pulling force at both ends of the broken intestine during suturing, avoid rigid impact between the inflatable closing mechanism and the moving mechanism, and ensure stable alignment of the broken intestine ends during suturing; Step 3: Inflation and Closure Mechanism: The first and second airbags are inflated to secure the two ends of the severed intestine. An electric hydraulic telescopic rod drives the second sleeve toward the first sleeve, bringing the ends of the severed intestine fixed by the airbags into close contact, facilitating suturing. The smooth, rounded head design reduces resistance to movement within the intestine, and an external air pump connected to the delivery tube allows for rapid inflation and deflation of the airbags. Step 4: Outer diameter opening and closing mechanism: The outer diameter of the intestinal wall is clamped by the upper outer diameter clamping ring and the lower outer diameter clamping ring, and the intestinal wall is temporarily fixed with the clamping handle and the clamping head. After the suturing is completed, the clamping is released and the air bag pressure is released, and the tool can be safely removed by the traction rope. From the above, it can be seen that the copper mine waste slag treatment method and equipment provided by the present invention have the following technical effects.

[0020] First, the operation of the first motor drives the transmission gear to rotate, and the rotation of the transmission gear drives the inclined mounting cylinder to rotate through the driven gear plate. Under the action of the resistance-increasing ribs, the steel balls are moved up to a certain height as the inclined mounting cylinder rotates and then fall down, crushing the slag in the inclined mounting cylinder. This reciprocating motion can fully crush the slag, avoiding the impact of insufficient force on the crushing effect of the slag due to the falling ball. At the same time, through the design of the feed port and the discharge port, the device can continuously perform ball milling on the slag without stopping for unloading.

[0021] Second, the copper slag to be crushed is poured into the obliquely installed cylinder through the feed cylinder. During this period, the hot air blower blows hot air into the annular air cavity and blows it out through several air outlet holes, which can dry the slag in the feed cylinder, remove water vapor, and prevent moisture from affecting the ball milling effect of the slag.

[0022] Third: under the action of the coarse-hole mesh plate, slag powder crushed to a certain specification can be discharged, and the discharged slag powder falls into the collection box through the filter plate. Under the action of the filter plate, some larger slag particles can be filtered. During this period, the operation of the second motor drives the reciprocating screw to rotate. Under the guidance of the guide slider and the guide slide rod, the threaded block can drive the filter plate to reciprocate left and right through the rotation of the reciprocating screw, so that it reaches a shaking state, thereby improving the efficiency of screening slag powder.

[0038] Reference Figure 2 In a preferred embodiment, the drying mechanism includes a feed barrel 20 fixedly mounted above the base plate 1 through a support frame, the inner bottom wall of the feed barrel 20 is embedded with a feed pipe extending to the inside of the feed port 5, an annular air cavity 21 is opened inside the shell of the feed barrel 20, and an air outlet 22 is opened on the inner wall of the annular air cavity 21 and penetrates into the inside of the feed barrel 20, a hot air blower 23 is fixedly mounted on the upper surface of the base plate 1, and the air outlet end of the hot air blower 23 is connected to the inside of the annular air cavity 21.

[0039] There are a plurality of air outlet holes 22 , which are arranged in a circular array on the inner wall of the annular air cavity 21 .

[0040] The method for treating copper mine waste slag comprises the following steps: Step 1: Movement Mechanism 2: The first rubber hinge 201 on the outside of the mounting base 1 is linked to the elastic hydraulic telescopic rod 202, driving the adjustment frame 203 and its top rubber roller 204 to adaptively move along the intestinal wall. The traction rope and adjustment handle 6 adjust the front and back position of the mounting base 1. The elastic hydraulic telescopic rod 202 automatically expands and contracts according to the inner diameter of the intestine, ensuring that the rubber roller 204 always conforms to the intestinal wall, ensuring smooth movement of the tool within the intestine. Step 2: The telescopic buffer mechanism 3 is composed of a fixed limit column 301, a spring 302 and a first sleeve 303. The spring 302 provides elastic buffering to absorb the pulling force at both ends of the broken intestine during suturing, avoiding rigid impact between the inflatable closing mechanism 4 and the moving mechanism 2, and ensuring stable alignment of the broken intestine ends during suturing. Step 3: Inflation and closure mechanism 4: The first and second airbags 401, 405 are inflated to secure the two ends of the severed intestine. The electric hydraulic telescopic rod 402 drives the second sleeve 403 and the first sleeve 303 closer together, bringing the ends of the severed intestine fixed by the airbags into close contact, facilitating suturing. The smooth round head 406 design reduces the resistance to movement within the intestine, and the air delivery tube 404 is connected to an external air pump to achieve rapid inflation and deflation of the airbags. Step 4: Outer diameter opening and closing mechanism 5: The upper outer diameter locking ring 501 and the lower outer diameter locking ring 502 engage the outer diameter of the intestinal wall, and the locking handle 503 and the locking head 504 are used to temporarily fix the intestinal wall. After suturing is completed, the locking mechanism is released and the airbag pressure is released, and the tool can be safely removed via the traction rope.

[0041] Working principle: When in use, first put a number of steel balls into the inclined installation cylinder 4 through the feed cylinder 20 and the delivery pipe, and then pour the copper slag to be crushed into the inclined installation cylinder 4 through the feed cylinder 20. During this period, the operation of the hot air blower 23 blows hot air into the annular air cavity 21 and blows it out through a number of air outlets 22, which can dry the slag in the feed cylinder 20 and remove moisture. At this time, the operation of the first motor 9 drives the transmission gear 10 to rotate, and the rotation of the transmission gear 10 drives the inclined installation cylinder 4 to rotate through the driven gear plate 11. Under the action of the resistance-increasing ridges 8, the steel balls are moved up to a certain height as the inclined installation cylinder 4 rotates and then fall down. The slag in the obliquely installed cylinder 4 is crushed, and the slag can be fully crushed by this reciprocating motion. Subsequently, the slag powder crushed to a certain specification can be discharged under the action of the coarse-hole mesh plate 7, and the discharged slag powder falls into the collection box 13 through the filter plate 12. Under the action of the filter plate 12, some larger slag particles can be filtered. During this period, the operation of the second motor 14 drives the reciprocating screw 15 to rotate. Under the guidance of the guide slider 18 and the guide slide rod 17, the threaded block 16 can drive the filter plate 12 to reciprocate left and right through the rotation of the reciprocating screw 15, so that it reaches a shaking state, thereby improving the efficiency of screening the slag powder.
