Description

Technical Field

[0001] This utility model belongs to the field of casting technology, specifically, it relates to a slag cleaning device for a smelting furnace. Background Technology

[0002] Waste residue generated during the smelting of non-ferrous metal minerals is called non-ferrous metal slag, a type of metallurgical waste residue. According to the production process, it can be divided into two categories: molten slag formed in pyrometallurgical processes and residue discharged from hydrometallurgical processes. According to the properties of the metal minerals, it can be divided into heavy metal slag (such as copper slag, lead slag, zinc slag, nickel slag, etc.), light metal slag (such as red mud produced from alumina refining), and rare metal slag.

[0003] A document with publication number (CN218168717U) discloses an automated slag removal device, including a mobile base. The top of the mobile base is symmetrically equipped with damping shock absorbers, and the top of the damping shock absorbers is equipped with a collection box. The top of one side of the collection box is equipped with a frame. The inner cavity of the frame is equipped with a lifting mechanism, and the lifting mechanism is fixedly connected to the lifting box on one side via a slide rod.

[0004] However, in daily operation, the angle of the slag hopper is not adjustable, and the slag hopper is perpendicular to the slag in the furnace. This causes the slag hopper to fall out of the furnace opening when it carries the slag out of the furnace, causing the slag to adhere to the smelting furnace and be exposed to the environment, thus causing pollution.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A slag cleaning device for a smelting furnace includes a storage tank with a support frame and a base at the lower end. A support plate is mounted on the support frame, and a hydraulic press is fixedly mounted on the support plate. A lifting motor is mounted on one end of the hydraulic press, and a lifting plate is fixedly connected to the output shaft of the lifting motor. Second telescopic motors are fixedly connected to the four corners of the lifting plate, and grab buckets are rotatably connected to the lower ends of the second telescopic motors. A first telescopic motor is fixedly connected to the lower end of the support plate, and a knocking rod is provided in the middle of the first telescopic motor.

[0008] In a preferred embodiment of this utility model, the output shaft of the second telescopic motor is fixedly connected to a ball head, and a ball socket is provided on the grab bucket, with the ball head rotating to connect to the ball socket.

[0009] In a preferred embodiment of this utility model, the grab bucket is provided with multiple holes, the grab bucket is crescent-shaped, and the opening of the grab bucket is chamfered.

[0010] In a preferred embodiment of this utility model, a threaded rod is rotatably connected inside the bracket, and a servo motor is provided at the end of the threaded rod. The servo motor is fixedly connected to the bracket, and the threaded rod is threadedly connected to the support plate.

[0011] In a preferred embodiment of this utility model, the hydraulic press has a push rod connected to the output in the middle, and the other end of the push rod is fixedly connected to a lifting motor.

[0012] In a preferred embodiment of this utility model, a lead screw is rotatably connected to the middle of the base, a drive motor is provided in the middle of the lead screw, the drive motor is fixedly connected to the base, and sliders are threaded to both ends of the lead screw, and the sliders are slidably connected.

[0013] In a preferred embodiment of this utility model, each slider has a support rod axially connected to one end, and a fixing block is axially connected to the other end of the support rod. The fixing block is slidably connected to the bottom of the storage box.

[0014] In a preferred embodiment of this utility model, the threads at both ends of the lead screw are in opposite directions, and the slider moves in the opposite direction through the threads in opposite directions. The bottom end of the base is rotatably connected to a universal wheel.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. This slag cleaning device for a smelting furnace includes a lifting motor that drives a lifting plate to rise and fall via its output shaft. The four corners of the lifting plate are equipped with second telescopic motors that can independently adjust the grab bucket. The different lengths of the output shafts of these motors allow the grab bucket to rotate in an arc shape during operation. This arc-shaped rotation of the grab bucket scoops up suspended slag, expanding the range of slag scooping and preventing slag from falling from the grab bucket and being exposed to the environment, thus improving the device's efficiency. Simultaneously, the molten metal leaks out through the drain hole, reducing waste and improving resource utilization efficiency, further enhancing the device's practicality.

[0017] 2. In this slag cleaning device for a smelting furnace, after the grab bucket scoops out the slag, it is driven by a hydraulic press to the storage tank. The grab bucket is tilted by the output shaft of the second telescopic motor on one side of the opening. The tilted grab bucket pours out the slag inside. At the same time, the first telescopic motor drives the knocking rod to extend and retract rapidly through the output shaft. The knocking rod strikes the grab bucket by extending and retracting rapidly, knocking off the slag adhering to the grab bucket, avoiding blockage of the leakage hole, and improving the practicality of the device.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] Please see Figure 1-5 A terminal block outer diameter machining device includes a storage box 1, a support 3 on the storage box 1, a base 4 mounted on the lower end of the storage box 1, a support plate 2 on the support 3, a hydraulic press 201 fixedly mounted on the support plate 2, a lifting motor 601 mounted on one end of the hydraulic press 201, a lifting plate 6 fixedly connected to the output shaft of the lifting motor 601, and second telescopic motors 602 fixedly connected to each of the four corners of the lifting plate 6. A grab bucket 603 is rotatably connected to the lower end of the second telescopic motors 602, and a first telescopic motor 203 is fixedly connected to the lower end of the support plate 2. A striking rod is provided in the middle of the first telescopic motor 203. 204. At this time, the hydraulic press 201 drives the push rod 202 to reciprocate through the output shaft. The reciprocating extension and retraction of the push rod 202 drives the lifting motor 601 at one end to move. The lifting motor 601 drives the lifting plate 6 to rise and fall through the output shaft. The second extension motors 602 at the four corners of the lifting plate 6 can independently adjust the grab bucket 603. By using the different lengths of the output shafts of the second extension motors 602 at the four corners, the grab bucket 603 can rotate in an arc shape when working. The arc rotation of the grab bucket 603 lifts up the suspended non-ferrous metal slag, expanding the range of slag that the device can lift, thereby improving the working efficiency of the device.

[0028] Specifically, the output shaft of the second telescopic motor 602 is fixedly connected to a ball head, and a ball socket is provided on the grab bucket 603. The ball head rotates and connects to the ball socket. Through the cooperation between the ball head and the ball socket, the grab bucket 603 can rotate in an arc shape when working.

[0029] Specifically, the grab bucket 603 has multiple drain holes 604. The grab bucket 603 is crescent-shaped, and the opening of the grab bucket 603 is chamfered. The chamfering reduces the contact between the grab bucket 603 and the molten metal, thereby improving the slag removal effect of the grab bucket 603. The molten metal leaks out through the drain holes 604, reducing the waste of molten metal, improving resource utilization efficiency, and further enhancing the practicality of the device.

[0030] Specifically, a threaded rod 302 is rotatably connected inside the bracket 3. A servo motor 301 is provided at the end of the threaded rod 302. The servo motor 301 is fixedly connected to the bracket 3. The threaded rod 302 is threadedly connected to the support plate 2. The servo motor 301 drives the threaded rod 302 to rotate through the output shaft. The rotation of the threaded rod 302 drives the support plate 2 to rise and fall to a suitable working position through threaded transmission.

[0031] Specifically, the hydraulic press 201 has a push rod 202 connected to the middle via an output, and the other end of the push rod 202 is fixedly connected to a lifting motor 601. The hydraulic press 201 drives the push rod 202 to reciprocate through the output shaft, and the reciprocating extension and retraction of the push rod 202 drives the lifting motor 601 at one end to move.

[0032] Specifically, a lead screw 401 is rotatably connected to the middle of the base 4, and a drive motor 402 is provided in the middle of the lead screw 401. The drive motor 402 is fixedly connected to the base 4. Slider 403 is threaded to both ends of the lead screw 401. The slider 403 is slidably connected to the base 4. The drive motor 402 drives the lead screw 401 to rotate through the output shaft. The rotation of the lead screw 401 drives the slider 403 at both ends to move in the opposite direction through the opposite thread directions at both ends.

[0033] Specifically, each slider 403 has a support rod 404 axially connected to one end, and a fixing block 405 axially connected to the other end of the support rod 404. The fixing block 405 is slidably connected to the bottom of the storage box 1. When the slider 403 moves, it pushes one end of the support rod 404 to move, and the other end pushes the fixing block 405 to rise and fall. The fixing block 405 slides at the bottom of the storage box 1 and moves towards each other, thereby changing the working height of the storage box 1.

[0034] Specifically, the threads at both ends of the lead screw 401 are in opposite directions, and the slider 403 moves in the opposite direction through the threads in opposite directions. The bottom end of the base 4 is rotatably connected to a universal wheel 5, and the device rotates by contacting the ground with the universal wheel 5.

[0035] Working Principle: This device rotates by using casters 5 to contact the ground, moving it to a suitable working position. At this time, the drive motor 402 drives the lead screw 401 to rotate via its output shaft. The rotation of the lead screw 401 drives the sliders 403 at both ends to move in opposite directions via their opposing threads. The movement of the sliders 403 pushes one end of the support rod 404 to move, while the other end pushes the fixed block 405 to rise and fall. The fixed block 405 slides at the bottom of the storage box 1 and moves towards each other, thus changing the working height of the storage box 1. The servo motor 301 drives the threaded rod 302 to rotate via its output shaft. The rotation of the threaded rod 302 drives the support plate 2 to rise and fall to a suitable working position via threaded transmission. At this time, the hydraulic press 201 drives the push rod 202 to reciprocate via its output shaft. The reciprocating extension and retraction of the push rod 202 drives the lifting motor 601 at one end to move. The lifting motor 601 drives the lifting plate 6 to rise and fall via its output shaft. The second extension motors 602 at the four corners of the lifting plate 6 can independently move the grab bucket 603. The grab bucket 603 can rotate in an arc shape during operation by adjusting the output shaft lengths of the second telescopic motors 602 at the four corners. This arc rotation of the grab bucket 603 scoops up the suspended non-ferrous metal slag, expanding the range of slag scooping and thus improving the working efficiency of the device. At the same time, the molten metal leaks out through the drain hole 604, reducing waste of the molten metal and improving resource utilization efficiency, further enhancing the practicality of the device. After the grab bucket 603 scoops up the non-ferrous metal slag, it is driven by the hydraulic press 201 to the storage tank 1. The opening side of the grab bucket 603 is pushed downward by the output shaft of the second telescopic motor 602, causing the grab bucket 603 to tilt. The tilted grab bucket 603 pours out the non-ferrous metal slag inside. Simultaneously, the first telescopic motor 203 drives the knocking rod 204 to quickly extend and retract through its output shaft. The knocking rod 204 quickly extends and retracts, striking the grab bucket 603 and knocking off the non-ferrous metal slag adhering to the grab bucket 603, preventing the drain hole 604 from becoming blocked and improving the practicality of the device.
