Description

Technical Field

[0001] This utility model relates to the field of calcium carbide furnace material processing technology, specifically to a calcium carbide furnace material surface processing device. Background Technology

[0002] Currently, in the smelting industry, the surface treatment layer of the submerged arc furnace is also the combustion layer. During the combustion process of the raw materials in the furnace, they need to be processed by tamping, picking, pushing and adding materials to make the raw materials evenly distributed, expand the reaction zone, eliminate suspended materials, crush slag, reduce crusting and surface flame spraying, and increase the permeability of the furnace charge to improve smelting efficiency and utilization.

[0003] In the submerged arc furnace smelting industry, operators typically work from forklifts at the furnace door. During material handling, the equipment is extremely close to the furnace, with temperatures at the furnace door often reaching 400-500°C. The temperature at the point of contact between the material surface and the equipment inside the furnace exceeds 1300°C, causing a rapid and dramatic increase in both surface and internal temperatures. Current material handling devices use a hydraulic system to drive the furnace arm. However, when the hydraulic oil temperature is high, its viscosity changes, altering its power performance and potentially leading to insufficient power or even complete failure. Utility Model Content

[0004] The purpose of this utility model is to provide a calcium carbide furnace material surface treatment device, which solves the problem that the furnace arm of the existing material surface treatment device is driven by a hydraulic system. When the hydraulic oil temperature is high, the viscosity of the hydraulic oil will change, which will cause its power performance to change, resulting in insufficient power or even complete failure.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A calcium carbide furnace feed surface treatment device includes a drive vehicle and a lifting platform that can be vertically lifted and lowered at the front of the drive vehicle. A drive motor is mounted on the front side of the lifting platform via a mounting base. The output shaft of the drive motor is horizontally positioned away from the drive vehicle and connected to a horizontally positioned lead screw. A drive rod is threaded onto the outer side of the lead screw. A support sleeve is fitted onto the outer side of the drive motor. One end of the support sleeve is fixedly connected to the mounting base, and the other end is horizontally positioned away from the drive vehicle, so that the drive rod can be slidably inserted into the support sleeve. A groove is formed along the axis of the inner wall of the support sleeve. A slider is fixedly mounted on the outer wall of the drive rod and slidably placed in the groove. The end of the drive rod away from the drive vehicle extends out of the support sleeve and is connected to a tool rod.

[0007] A further technical solution is that a connecting seat is connected to the end of the drive rod away from the drive vehicle, and a connecting groove with a convex cross-section is vertically opened on the side of the connecting seat away from the drive rod. An opening communicating with the top of the connecting groove is opened on the top side of the connecting seat, and a connecting block that matches the connecting groove is fixed on the mounting end of the tool rod.

[0008] A further technical solution is that a limiting circular groove is formed on the side wall of the connecting groove near the opening, and a locking block is protruding on the groove wall of the limiting circular groove. A sliding hole communicating with the connecting groove is formed on the side of the connecting seat away from the limiting circular groove. A limiting rod is slidably inserted into the sliding hole. A locking groove is formed on the outer wall of the end of the limiting rod facing the limiting circular groove, and a sliding entrance communicating with the locking groove is formed at the end of the limiting rod facing the limiting circular groove.

[0009] A further technical solution is to provide a handle at the end of the limiting rod away from the sliding entrance.

[0010] A further technical solution is to spray a heat-insulating coating on the outer wall of both the support sleeve and the drive rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The material surface is processed by setting up a drive motor, lead screw, drive rod, and support sleeve in conjunction with the drive tool rod. The mechanical structure of the lead screw, drive rod, and support sleeve drives the extension and retraction of the tool rod. The mechanical structure of the lead screw, drive rod, and support sleeve is not easily affected by temperature, which would cause its power to change during use. This replaces the traditional hydraulic system drive and prevents the hydraulic oil viscosity from changing when the temperature is high, which would lead to changes in its power performance, resulting in insufficient power or even complete failure, thus avoiding affecting the material surface processing efficiency.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Example:

[0019] See Figure 1 , Figure 2 As shown, this utility model discloses a calcium carbide furnace feed surface processing device, including a drive vehicle 1 and a lifting platform 2 vertically and elevatingly mounted at the front of the drive vehicle 1. The lifting platform 2 is vertically and elevatingly mounted at the front of the drive vehicle 1 using existing forklift technology, such as a lifting mast and lifting mechanism. The structure of the drive vehicle 1 is common knowledge to those skilled in the art, and those skilled in the art can directly obtain the corresponding installation relationship and structure based on common knowledge. A drive motor 4 is mounted on the front side of the lifting platform 2 via a mounting base 3. The output shaft of the drive motor 4 is horizontally away from the load. A drive vehicle 1 is provided and connected to a horizontally positioned lead screw 5. A drive rod 6 is threaded onto the outer side of the lead screw 5. A support sleeve 7 is fitted onto the outer side of the drive motor 4. One end of the support sleeve 7 is fixedly connected to the mounting base 3, and the other end is horizontally positioned away from the drive vehicle 1 so that the drive rod 6 can be slidably inserted into the support sleeve 7. A groove 8 is provided along the axis of the inner wall of the support sleeve 7. A slider 9 is fixedly provided on the outer wall of the drive rod 6 and slidably placed in the groove 8. The end of the drive rod 6 away from the drive vehicle 1 extends out of the support sleeve 7 and is connected to a tool rod 11.

[0020] The mounting base 3 can be embedded with a heat dissipation pipe, with coolant connected to both ends of the heat dissipation pipe for heat dissipation. This structure is common knowledge to those skilled in the art, and those skilled in the art can directly obtain the corresponding installation relationship and structure based on common knowledge. By setting the sliding groove 8 and the slider 9, the drive rod 6 can be prevented from rotating with the lead screw 5 when the drive motor 4 drives the lead screw 5 to rotate. At the same time, the drive rod 6 can be prevented from sliding completely out of the support sleeve 7. It should be noted that controlling the operation of the drive motor 4 through the console is existing technology and will not be described in detail here.

[0021] In operation, when refractory materials need to be removed from the calcium carbide furnace, the drive vehicle 1 moves the tool rod 11 to the front of the furnace and places it inside. The lifting platform 2 is then raised and lowered to align the tool rod 11 with the material surface. The drive motor 4 then operates, causing its output shaft to rotate the lead screw 5. The lead screw 5 engages with the drive rod 6, which extends from the support sleeve 7, moving the tool rod 11 and thus processing the material surface. This system, using the drive motor 4, lead screw 5, drive rod 6, and support sleeve 7 in conjunction with the tool rod 11, replaces the traditional hydraulic system. This prevents changes in hydraulic oil viscosity at higher temperatures, which could alter the hydraulic performance, leading to insufficient power or even complete failure, thus ensuring efficient material processing.

[0022] As a preferred implementation method, see [link / reference] Figures 1 to 3 As shown, the end of the drive rod 6 away from the drive vehicle 1 is connected to a connecting seat 12. The connecting seat 12 has a vertically convex connecting groove 13 on the side away from the drive rod 6. The top side of the connecting seat 12 has an opening 14 that communicates with the top of the connecting groove 13. A connecting block 15 that matches the connecting groove 13 is fixedly provided on the mounting end of the tool rod 11. In use, the connecting block 15 is inserted and slid into the connecting groove 13 through the opening 14, thereby realizing the connection and installation of the tool rod 11 and the drive rod 6. Conversely, when disassembling the tool rod 11, the connecting block 15 is simply slid out of the connecting groove 13 through the opening 14 to complete the disassembly. By setting the connecting groove 13 and the connecting block 15, it is easy to quickly disassemble and assemble the tool rod 11, thereby facilitating the quick replacement of the damaged tool rod 11 or the replacement of different types of tool rods 11 for material surface treatment. It should be noted that manufacturing different types of tool rods 11 according to actual needs is existing technology and will not be described in detail here.

[0023] As a preferred implementation method, see [link / reference] Figure 3As shown, a limiting circular groove 16 is formed on the side wall of the connecting groove 13 near the opening 14. A locking block 17 protrudes from the groove wall of the limiting circular groove 16. A sliding hole 18 communicating with the connecting groove 13 is formed on the side of the connecting seat 12 away from the limiting circular groove 16. The limiting circular groove 16 and the sliding hole 18 are at the same horizontal position. A limiting rod 19 is slidably inserted into the sliding hole 18. A locking groove 20 is formed on the outer wall of the end of the limiting rod 19 facing the limiting circular groove 16. A sliding entrance 21 communicating with the locking groove 20 is formed at the end of the limiting rod 19 facing the limiting circular groove 16. In use, after the tool rod 11 is connected and installed to the drive rod 6 through the connecting groove 13 and the connecting block 15, the limiting rod 19 is passed through the sliding hole 18, so that the limiting rod 19... The sliding inlet 21 at the end is aligned with the locking block 17, and then the limiting rod 19 is pushed so that the locking block 17 slides into the locking groove 20 through the sliding inlet 21. At the same time, the limiting rod 19 slides into the limiting circular groove 16. Then the limiting rod 19 is rotated so that the locking block 17 is placed at the end of the locking groove 20 away from the sliding inlet 21. The locking block 17 abuts against the groove wall of the locking groove 20 to prevent the limiting rod 19 from sliding out of the limiting circular groove 16. By setting the limiting rod 19, the connecting block 15 is blocked, ensuring the stability of the tool rod 11 connected and installed at the end of the drive rod 6 through the connecting block 15 and the connecting groove 13. It should be noted that the groove wall distance between the two sides of the locking groove 20 away from the sliding inlet 21 is smaller than the groove wall distance between the two sides of the locking groove 20 close to the sliding inlet 21.

[0024] As a preferred implementation method, see [link / reference] Figure 3 As shown, a handle 22 is provided at the end of the limiting rod 19 away from the sliding entrance 21. The handle 22 facilitates the operation of the limiting rod 19.

[0025] In a preferred embodiment, both the outer walls of the support sleeve 7 and the drive rod 6 are coated with a heat-insulating coating. The heat-insulating coating is made of a heat-insulating coating that isolates conduction. This heat-insulating coating can effectively limit the temperature transfer from the calcium carbide furnace to the interior of the support sleeve 7.

[0026] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
