Description

Technical Field

[0001] The invention belongs to the technical field of powder metallurgy production, and in particular relates to a silver tungsten carbide graphite waste material recovery and treatment device and a treatment method. Background Art

[0002] Silver tungsten carbide graphite waste recycling and treatment device is a kind of equipment specially used for recycling waste materials containing silver, tungsten carbide and graphite. It uses specific process technology and mechanical structure, through a series of operations such as separation and purification, to extract valuable components from these wastes, realize resource reuse, and reduce adverse effects on the environment. It plays an important role in the relevant industrial waste treatment and resource recycling fields.

[0003] Silver tungsten carbide graphite waste needs to be crushed in a processing box, and then recycled after being crushed to a suitable size. The processing equipment performs the crushing operation through a crushing roller, and the crushed waste will fall on the screen. The holes in the screen can screen the waste of suitable size so that it can be used for subsequent operations, while the larger waste that is not completely crushed will remain on the screen and needs to be crushed again to a suitable size before it can be discharged. In some existing technologies, the screen is generally fixed in the processing box by bolts and cannot be moved. When the waste falls on the screen, it may accumulate in a certain place, resulting in unevenness and affecting the screening effect. Therefore, in view of the above problems, a silver tungsten carbide graphite waste recycling and processing device and processing method are proposed. Summary of the invention

[0007] Preferably, the motor is fixedly connected to the outer wall of the processing box, the sprocket A and the sprocket B are both rotatably connected to the outer wall of the processing box, one end of the connecting rod is hinged to the outer wall of the rotating rod, and the other end of the connecting rod is hinged to the outer wall of the trapezoidal block.

[0008] Preferably, one end of the connecting spring is fixedly connected to the inner wall of the processing box, and the other end of the connecting spring is fixedly connected to the outer wall of the moving frame.

[0009] Preferably, one end of the slide rod is slidably connected to the outer wall of the trapezoidal block, the other end of the slide rod is fixedly connected to the outer wall of the moving frame, and the moving frame is slidably connected to the inner wall of the processing box.

[0010] Preferably, the pressing mechanism includes a cylinder, the movable end of the cylinder is fixedly connected to a moving block, the outer wall of the moving block is fixedly connected to a convex rod, the bottom outer wall of the moving block is fixedly connected to a pressure block, the outer wall of the pressure block is fixedly connected to a moving rod, and the outer wall of the moving rod is hinged to a slider via a hinge rod.

[0011] Preferably, the cylinder is fixedly connected to the top outer wall of the processing box, the moving block is slidably connected to the inner wall of the processing box, and the moving rod is slidably connected to the inner wall of the processing box.

[0012] Preferably, one end of the hinged rod is hinged to the outer wall of the slider, the other end of the hinged rod is hinged to the outer wall of the moving rod, and the crushing roller is rotatably connected to the outer wall of the slider.

[0013] Preferably, the shielding mechanism comprises a fixed block, the inner wall of the fixed block is elastically connected to a rotating rod via a spiral spring, a barrier curtain is wound around the outer wall of the rotating rod, and a handle is fixedly connected to the outer wall of the barrier curtain.

[0014] Preferably, the fixed block is fixedly connected to the outer wall of the processing box, one end of the spiral spring is fixedly connected to the inner wall of the rotating rod, the other end of the spiral spring is fixedly connected to the inner wall of the fixed block, and the rotating rod is rotatably connected to the inner wall of the fixed block.

[0015] The present application also proposes a method for recycling silver tungsten carbide graphite waste, comprising the following steps:

[0016] S1. Start the conveying module to convey the silver tungsten carbide graphite waste from the outside to the inside of the processing box. Two sets of crushing rollers start working to perform preliminary crushing operations on the waste entering the processing box to reduce the volume of the waste for subsequent processing;

[0017] S2. Start the motor of the screening mechanism to drive the sprocket A and the sprocket B to rotate synchronously. The sprocket B drives the rotating rod to rotate. The rotating rod drives the trapezoidal block to move up and down reciprocatingly through the connecting rod. The inclined surface of the trapezoidal block cooperates with the sliding rod, so that the sliding rod drives the moving frame to move reciprocatingly and horizontally. Under the action of the connecting spring, a stable reciprocating motion is formed, so that the screen can screen the waste and make the waste accumulation more uniform, thereby improving the screening efficiency. The waste that meets the screen aperture falls down, and the larger waste remains above the screen.

[0018] S3. When there is a lot of waste above the screen, start the cylinder of the downward pressing mechanism, the cylinder pushes the moving block downward, the moving rod moves downward synchronously and the slider moves to both sides through the hinge rod, driving the crushing roller to move to both sides to make room for the pressing block to press down. The pressing block presses down the material in the processing box to reduce the occupied space and avoid accumulation affecting the subsequent screening;

[0019] S4. When the cylinder pushes the moving block downward, the protruding rod contacts the handle of the shielding mechanism and exerts a downward force on the handle. The handle pulls the curtain to gradually unfold, the rotating rod rotates, the scroll spring is forced to shrink, and the curtain blocks the front opening of the processing box to prevent the material from splashing out of the processing box during the compression process. When the cylinder drives the protruding rod to rise and return to its position, the elastic force of the scroll spring causes the rotating rod to reverse, and the curtain automatically retracts, and the operator can observe the internal material situation through the front opening of the processing box again;

[0020] S5. After screening, the crushed waste that meets the requirements falls through the holes of the screen and is discharged from the discharge port, completing the recycling process of silver tungsten carbide graphite waste. The whole process can be circulated until all the waste is processed to meet the requirements and discharged.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention cooperates with structures such as a motor and a trapezoidal block, and starts the motor to drive the trapezoidal block to move back and forth vertically through the sprocket A, the chain, and the sprocket B, and drives the moving frame to move back and forth horizontally through the slide bar. The waste material crushed by the crushing roller will fall on the screen. The waste material can be piled up more evenly through the continuous movement of the moving frame and the screen, thereby avoiding the problem of the waste material falling on the screen and piling up in one place, which affects the screening efficiency.

[0023] The present invention cooperates with structures such as a cylinder and a pressing block, and the cylinder can drive the moving block and the pressing block to press downward. During the pressing process, the hinged rod can drive the two groups of crushing rollers to move to both sides at the same time, which will not affect the pressing movement of the pressing block. The pressing of the pressing block can squeeze the larger waste remaining on the screen, thereby reducing the space occupied by the waste, and will not affect the screening of the waste.

[0024] The present invention cooperates with structures such as a curtain and a fixed block. During the downward pressing process of the moving block and the pressing block, the convex block will exert downward pressure on the handle, so that the handle pulls the curtain to extend and covers the front end opening of the processing box. After the downward pressing is completed, the scroll spring will drive the curtain to automatically retract into the fixed block, opening the front end opening of the processing box so that the operator can observe the crushing situation, thereby avoiding the waste from splashing or popping out during the waste extrusion process, which will affect the operator or the working environment.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 4 As shown, the present invention provides a silver tungsten carbide graphite waste recycling and processing device, including a processing box 1, the outer wall of the processing box 1 is provided with a conveying module 5, the outer wall of the processing box 1 is provided with a discharge port 6, the inner wall of the processing box 1 is provided with a crushing roller 7, the inner wall of the processing box 1 is provided with a pressing mechanism 3, the outer wall of the processing box 1 is provided with a shielding mechanism 4, and the outer wall of the processing box 1 is provided with a screening mechanism 2; the screening mechanism 2 includes a motor 201, the output shaft of the motor 201 is fixedly connected with a sprocket A202, the outer wall of the sprocket A202 is connected with a sprocket B204 through a chain 203, the outer wall of the sprocket B204 is fixedly connected with a rotating rod 205, the outer wall of the rotating rod 205 is hinged with a trapezoidal block 207 through a connecting rod 206, the inner wall of the processing box 1 is slidably connected with a sliding rod 208, the inner wall of the processing box 1 is elastically connected with a moving frame 210 through a connecting spring 209, and the inner wall of the moving frame 210 is fixedly connected with a screen 211.

[0035] The above scheme is adopted: the processing box 1 is the outer shell body of the silver tungsten carbide graphite waste recycling and processing device, the silver tungsten carbide graphite waste can be transported from the outside to the inside of the processing box 1 through the conveying module 5, and is crushed by two sets of crushing rollers 7, and the crushed silver tungsten carbide graphite waste passes through the screening mechanism 2, and the waste that is not completely crushed will remain on the screen 211, while the completely crushed waste will fall through the holes of the screen 211 and be discharged from the discharge port 6; the motor 201 is the power source of the screening mechanism 2, and after starting, it drives the sprocket A202 to rotate, and through the transmission of the chain 203, the sprocket B204 rotates synchronously therewith; the outer walls of the sprocket A202 and the sprocket B204 are both provided with tooth blocks, and the chain 203 is an annular component composed of multiple chain links, and the sprocket A20 When the motor 201 rotates, its outer wall tooth blocks mesh with the chain links of the chain 203. Under the force of the sprocket A202 tooth blocks on the chain 203, the chain 203 starts to move with the rotation of the sprocket A202, and transmits the power to the sprocket B204, so that the sprocket A202 and the sprocket B204 can rotate synchronously, which is the prior art; the sprocket B204 can drive the rotating rod 205 to rotate synchronously, and drive the trapezoidal block 207 to move through the hinge relationship between the connecting rod 206 and the trapezoidal block 207; because the trapezoidal block 207 is slidably connected to the outer wall of the processing box 1, it can only move up and down, so that the sprocket B204, the rotating rod 205, the connecting rod 206 and the trapezoidal block 207 perform a crank connecting rod motion, driving the trapezoidal block 207 to move up and down reciprocatingly.

[0036] like Figures 1 to 4 As shown, the motor 201 is fixedly connected to the outer wall of the processing box 1, the sprocket A202 and the sprocket B204 are both rotatably connected to the outer wall of the processing box 1, one end of the connecting rod 206 is hinged to the outer wall of the rotating rod 205, and the other end of the connecting rod 206 is hinged to the outer wall of the trapezoidal block 207; one end of the connecting spring 209 is fixedly connected to the inner wall of the processing box 1, and the other end of the connecting spring 209 is fixedly connected to the outer wall of the moving frame 210; one end of the sliding rod 208 is slidably connected to the outer wall of the trapezoidal block 207, and the other end of the sliding rod 208 is fixedly connected to the outer wall of the moving frame 210, and the moving frame 210 is slidably connected to the inner wall of the processing box 1.

[0037] The above scheme is adopted: one end of the slide bar 208 is slidably connected with the inclined surface of the trapezoidal block 207. When the trapezoidal block 207 moves back and forth vertically, its inclined surface will drive the slide bar 208 to move back and forth horizontally, and the sliding bar 208 drives the moving frame 210 to move synchronously; when the trapezoidal block 207 and the sliding bar 208 push the moving frame 210 to move a certain distance, the connecting spring 209 is stretched by force, and when the trapezoidal block 207 and the sliding bar 208 move in the opposite direction, under the elastic force of the connecting spring 209, the moving frame 210 will reset again, thereby forming a reciprocating motion, and the screen 211 inside the moving frame 210 will screen the material in the processing box 1 under the reciprocating motion of the moving frame 210, so that the material that meets the aperture of the screen 211 falls down, and the material that does not meet the aperture remains above the screen 211, so as to further crush and process, and improve the screening efficiency, avoid the waste material from accumulating in one place of the screen 211, and make it more uniform.

[0038] like Figure 5 As shown, the pressing mechanism 3 includes a cylinder 301, the movable end of the cylinder 301 is fixedly connected to a moving block 302, the outer wall of the moving block 302 is fixedly connected to a convex rod 8, the outer wall of the bottom end of the moving block 302 is fixedly connected to a pressing block 303, the outer wall of the pressing block 303 is fixedly connected to a moving rod 304, and the outer wall of the moving rod 304 is hinged to a slider 306 through a hinge rod 305; the cylinder 301 is fixedly connected to the top outer wall of the processing box 1, the moving block 302 is slidably connected to the inner wall of the processing box 1, and the moving rod 304 is slidably connected to the inner wall of the processing box 1; one end of the hinge rod 305 is hinged to the outer wall of the slider 306, and the other end of the hinge rod 305 is hinged to the outer wall of the moving rod 304, and the crushing roller 7 is rotatably connected to the outer wall of the slider 306.

[0039] The above scheme is adopted: when the cylinder 301 is started, its movable end pushes the moving block 302 to move downward, and the convex rod 8 on the outer wall of the moving block 302 descends together with the moving block 302. When the convex rod 8 descends, it will generate pressure on the handle 405 in the shielding mechanism 4, driving the shielding mechanism 4; the pressing block 303 at the bottom end of the moving block 302 is used to press down the material in the processing box 1, so that the material can be better processed during the crushing process of the crushing roller 7, avoiding the accumulation of materials affecting the crushing effect; the moving rod 304 on the moving block 302 is slidably connected to the inner wall of the processing box 1, ensuring that the moving rod 304 will be synchronized with the moving block 302 Vertical movement; through the hinged relationship between the hinged rod 305 and the slider 306, when the moving rod 304 moves downward with the moving block 302, the two sets of hinged rods 305 will flip to both sides, driving the two sets of sliders 306 to move to both sides; since the crushing roller 7 is rotatably connected to the outer wall of the slider 306, when the slider 306 moves to both sides, it will drive the two sets of crushing rollers 7 to move synchronously, so that the crushing roller 7 will not block the pressing block 303 from pressing down; and when the movable end of the cylinder 301 drives the pressing block 303 to move upward and reset, the moving rod 304 will drive the two sets of sliders 306 to move to the middle at the same time through the hinged rod 305, so that the crushing roller 7 moves synchronously and resets.

[0040] like Figure 6 to Figure 7 As shown, the shielding mechanism 4 includes a fixed block 401, the inner wall of the fixed block 401 is elastically connected to the rotating rod 402 through a spiral spring 403, the outer wall of the rotating rod 402 is wrapped with a curtain 404, and the outer wall of the curtain 404 is fixedly connected to a handle 405; the fixed block 401 is fixedly connected to the outer wall of the processing box 1, one end of the spiral spring 403 is fixedly connected to the inner wall of the rotating rod 402, the other end of the spiral spring 403 is fixedly connected to the inner wall of the fixed block 401, the rotating rod 402 is rotatably connected to the inner wall of the fixed block 401, and the handle 405 is in contact with the protruding rod 8.

[0041] The above scheme is adopted: when the volute spring 403 is in the initial state, the rotating rod 402 remains fixed, and the curtain 404 is wound around the outer wall of the rotating rod 402. At this time, the curtain 404 is in a retracted state, which does not affect the normal feeding or other operations of the processing box 1. The operator can observe the internal material crushing situation through the opening at the front end of the processing box 1; when the cylinder 301 pushes the moving block 302 to move downward, the protruding rod 8 contacts the handle 405, the protruding rod 8 applies a downward force to the handle 405, and the handle 405 pulls the curtain 404 to gradually unfold, and the other end of the curtain 404 drives the rotating rod 402 to rotate, and the volute spring 403 is forced to shrink; after the curtain 404 is unfolded, the front end opening of the processing box 1 can be blocked to prevent the material from splashing out of the processing box 1 during the compression process, which plays a role in protection and material collection control; when the cylinder 301 drives the protruding rod 8 to rise back to its original position, under the elastic force of the volute spring 403, the rotating rod 402 is reversed, and the curtain 404 can be automatically retracted.

[0042] The present application also proposes a method for recycling silver tungsten carbide graphite waste, comprising the following steps:

[0043] S1, start the conveying module 5, convey the silver tungsten carbide graphite waste from the outside to the inside of the processing box 1, and the two sets of crushing rollers 7 start working to perform preliminary crushing operations on the waste entering the processing box 1 to reduce the volume of the waste for subsequent processing;

[0044] S2, start the motor 201 of the screening mechanism 2, drive the sprocket A202 and the sprocket B204 to rotate synchronously, the sprocket B204 drives the rotating rod 205 to rotate, the rotating rod 205 drives the trapezoidal block 207 to move up and down reciprocatingly through the connecting rod 206, the inclined surface of the trapezoidal block 207 cooperates with the sliding rod 208, so that the sliding rod 208 drives the moving frame 210 to move reciprocatingly and laterally, and forms a stable reciprocating motion under the action of the connecting spring 209, so that the screen 211 can screen the waste and make the waste accumulation more uniform, thereby improving the screening efficiency, and the waste that meets the aperture of the screen 211 falls down, and the larger waste remains above the screen 211;

[0045] S3. When there is a lot of waste material above the screen 211, the cylinder 301 of the pressing mechanism 3 is started, and the cylinder 301 pushes the moving block 302 to move downward, and the moving rod 304 moves downward synchronously and moves the slider 306 to both sides through the hinge rod 305, driving the crushing roller 7 to move to both sides to make room for the pressing block 303 to press down. The pressing block 303 presses down the material in the processing box 1 to reduce the occupied space and avoid accumulation affecting the subsequent screening;

[0046] S4, when the cylinder 301 pushes the moving block 302 downward, the protruding rod 8 contacts the handle 405 of the shielding mechanism 4 and applies a downward force to the handle 405, and the handle 405 pulls the curtain 404 to gradually unfold, the rotating rod 402 rotates, the volute spring 403 is forced to shrink, and the curtain 404 blocks the front opening of the processing box 1 to prevent the material from splashing out of the processing box 1 during the compression process. When the cylinder 301 drives the protruding rod 8 to rise back to its original position, the elastic force of the volute spring 403 causes the rotating rod 402 to reverse, and the curtain 404 is automatically retracted, and the operator can observe the internal material situation through the front opening of the processing box 1 again;

[0047] S5. After screening, the crushed waste that meets the requirements falls through the holes of the screen 211 and is discharged from the discharge port 6, completing the recovery process of the silver tungsten carbide graphite waste. The whole process can be circulated until all the waste is processed to meet the requirements and discharged.

A method for recycling silver tungsten carbide graphite waste, applied to a silver tungsten carbide graphite waste recycling device as described in any of claims 1-9, characterized in that: The following steps are involved: S1, start the conveying module (5), convey the silver tungsten carbide graphite waste from the outside to the inside of the processing box (1), and the two sets of crushing rollers (7) start to work, and perform preliminary crushing operations on the waste entering the processing box (1), so as to reduce the volume of the waste and facilitate subsequent processing; S2, starting the motor (201) of the screening mechanism (2), driving the sprocket A (202) and the sprocket B (204) to rotate synchronously, the sprocket B (204) driving the rotating rod (205) to rotate, the rotating rod (205) driving the trapezoidal block (207) to move up and down reciprocatingly through the connecting rod (206), the inclined surface of the trapezoidal block (207) cooperates with the sliding rod (208), so that the sliding rod (208) drives the moving frame (210) to move reciprocatingly and laterally, and forms a stable reciprocating motion under the action of the connecting spring (209), so that the screen (211) can screen the waste and make the waste accumulation more uniform, thereby improving the screening efficiency, and the waste that meets the aperture of the screen (211) falls down, and the larger waste remains above the screen (211); S3. When there is a lot of waste material above the screen (211), the cylinder (301) of the pressing mechanism (3) is started, the cylinder (301) pushes the moving block (302) to move downward, the moving rod (304) moves downward synchronously and the slider (306) moves to both sides through the hinge rod (305), driving the crushing roller (7) to move to both sides, making room for the pressing block (303) to press downward, and the pressing block (303) presses down the material in the processing box (1) to reduce the occupied space and avoid accumulation affecting the subsequent screening; S4, when the cylinder (301) pushes the moving block (302) downward, the protruding rod (8) contacts the handle (405) of the shielding mechanism (4) and applies a downward force to the handle (405), and the handle (405) pulls the shielding curtain (404) to gradually unfold, the rotating rod (402) rotates, the spiral spring (403) is forced to shrink, and the shielding curtain (404) shields the front opening of the processing box (1) to prevent the material from splashing out of the processing box (1) during the compression process. When the cylinder (301) drives the protruding rod (8) to rise and return to its original position, the elastic force of the spiral spring (403) causes the rotating rod (402) to reverse, and the shielding curtain (404) is automatically retracted, and the operator can observe the internal material through the front opening of the processing box (1) again; S5. After screening, the crushed waste that meets the requirements falls through the holes of the screen (211) and is discharged from the discharge port (6), completing the recovery process of the silver tungsten carbide graphite waste. The whole process can be repeated until all the waste is processed to meet the requirements and discharged.
