[0038] Embodiments of the present application provide a calcium carbide furnace automatic oxygen blowing system, which is arranged in a calcium carbide production workshop, as shown in FIG. Figure 1 The system includes a suspension rod 100, a clamping assembly 200, an oxygen blowing assembly 300 and a furnace robot 400. The suspension rod 100 is fixed and provides a basis for mounting and suspension. The clamping assembly 200 is used to clamp the oxygen blowing pipe 310 of the oxygen blowing assembly 300. The oxygen blowing pipe 310 of the oxygen blowing assembly 300 can blow oxygen to the eye of the calcium carbide furnace. The furnace robot 400 is a robot arranged near the calcium carbide furnace and can realize automatic operation.

[0039] As shown in FIG. Figure 1 , Figure 2 and Figure 3As shown, the upper end of the suspension rod 100 is fixed on the roof of a production workshop (not shown in the figure), and the lower end of the suspension rod 100 is symmetrically rotatably connected with two rotating plates 110, the two rotating plates 110 are connected through a tensile spring 120, and the two rotating plates 110 can be artificially applied with an external force to realize mutual moving away (i.e. rotating along the direction of the arrow a in Figure 3 ), and after the external force is removed, the two rotating plates 110 can be moved close to each other (i.e. rotating along the direction of the arrow b in Figure 3 ) under the action of the pulling force of the tensile spring 120, so as to realize the installation and clamping of the support plate 210, facilitate the disassembly and assembly, and have a simple structure and easy operation.

[0040] As shown in Figure 3 , the side close to each other of the two rotating plates 110 (i.e. the inner side of the rotating plate 110) is rotatably connected with a roller 130, and the rotating shaft of the roller 130 is perpendicular to the rotating plate 110, so that the roller 130 is parallel to the rotating plate 110. When the two rotating plates 110 move away from each other, the two rollers 130 also move away from each other. When the two rotating plates 110 move close to each other, the two rollers 130 also move close to each other.

[0041] As shown in Figure 4 , Figure 5 and Figure 6 , the clamping assembly 200 comprises a support plate 210, an upper clamping piece 220 and a lower clamping piece 230, the support plate 210 is located above the roller 130 and abuts against the circumferential surface of the roller 130, that is, the support plate 210 is pressed above the roller 130 under the action of gravity.

[0042] The upper clamping piece 220 is arranged on the lower surface of the support plate 210 and located between the two rollers 130, that is, the width of the support plate 210 is greater than the width of the upper clamping piece 220 (the shapes of the support plate 210 and the upper clamping piece 220 can be generally regarded as T-shaped), so that a part of the support plate 210 is beyond the upper clamping piece 220, and this part is the part abutting against the roller 130. The lower clamping piece 230 is arranged below the upper clamping piece 220, and the upper clamping piece 220 and the lower clamping piece 230 are used to clamp the oxygen blowing pipe 310 to realize the clamping of the oxygen blowing pipe 310. In this way, the relative fixation between the oxygen blowing pipe 310 and the support plate 210 is realized.

[0043] As shown in Figure 1 , the oxygen blowing assembly 300 at least comprises an oxygen storage tank (not shown in the figure) and an oxygen blowing pipe 310, the oxygen blowing pipe 310 communicates with the oxygen storage tank through a connecting pipe (not shown in the figure), and the oxygen in the oxygen storage tank can enter the oxygen blowing pipe 310 through the connecting pipe to realize oxygen blowing. In the process of oxygen blowing, the oxygen blowing pipe 310 is located in a high-temperature area and will also be burned and gradually shortened, so the oxygen blowing pipe 310 needs to be continuously moved to the furnace eye to enable the oxygen sprayed from the oxygen blowing pipe 310 to reach the furnace eye.

[0044] As shown in Figure 1 , the mechanical arm of the tapping robot 400 is clamped to one end of the oxygen blowing pipe 310, and the tapping robot 400 can act according to the set program, so as to realize automatic control and operation, realize automatic control of the movement of the oxygen blowing pipe 310, so as to drive the oxygen blowing pipe 310 to approach or move away from the tuyere. The tapping robot 400 applies force to the oxygen blowing pipe 310, which is transmitted to the support plate 210, and the relative sliding occurs between the support plate 210 and the roller 130, so as to realize the linear stable movement of the support plate 210, that is, the linear stable movement of the whole of the support plate 210 and the oxygen blowing pipe 310, and the linear stable movement of the whole of the clamping assembly 200 and the oxygen blowing assembly 300.

[0045] In addition, the movement of the oxygen blowing pipe 310 can also be realized by other structures, such as chain cooperation motor, gear cooperation motor, etc., which will not be described in detail here.

[0046] The calcium carbide tapping automatic oxygen blowing system is installed in the production workshop of calcium carbide and is arranged near the calcium carbide furnace. The upper end of the suspension rod 100 can be fixed on the roof of the production workshop to realize fixation. The oxygen blowing assembly 300 is clamped by the clamping assembly 200 to realize relative fixation, that is, the support plate 210 and the oxygen blowing pipe 310 realize relative fixation. The support plate 210 is pressed on the roller 130, and the oxygen blowing pipe 310 is clamped by the mechanical arm of the tapping robot 400, so that the support plate 210 (oxygen blowing pipe 310) can be linearly and stably moved under the action of the tapping robot 400, so that the oxygen blowing pipe 310 can approach or move away from the tuyere of the calcium carbide furnace.

[0047] Compared with the prior art, the oxygen blowing pipe 310 and the support plate 210 of the calcium carbide tapping automatic oxygen blowing system realize relative fixation, the support plate 210 is pressed on the roller 130, and the mechanical arm of the tapping robot 400 clamps the oxygen blowing pipe 310, which can realize the movement of the oxygen blowing pipe 310 under the action of the tapping robot 400, realize the blowing of oxygen to the calcium carbide furnace, avoid manual blowing of oxygen by workers, thereby reduce the labor intensity, also avoid the workers from being scalded by splashing calcium carbide, and reduce the safety hidden danger.

[0048] In some embodiments, as shown in Figure 3 and Figure 6 , the two sides of the two rotating plates 110 close to each other are symmetrically provided with limiting plates 140, and the limiting plates 140 are perpendicular to the rotating plates 110. When the limiting plates 140 on both sides abut, the rotating plates 110 and the support plate 210 have a movement gap, that is, the rotating plates 110 and the support plate 210 are not in contact, and the rotating plates 110 will not affect the movement of the support plate 210. That is, the length after the abutment of the limiting plates 140 on both sides is greater than the width of the support plate 210, so as to form a movement gap between the support plate 210 and the rotating plate 110.

[0049] Similarly, as shown in Figure 6 , the rollers 130 should also have a gap with the upper clamping member 220 and the lower clamping member 230, so as not to affect the movement of the entire clamping assembly 200 and the oxygen blowing assembly 300. That is, the distance between the two rollers 130 is greater than the width of the upper clamping member 220 and the lower clamping member 230, so as to form a movement gap between the rollers 130 and the upper clamping member 220 and the lower clamping member 230.

[0050] Moreover, when the two limiting plates 140 abut, the rotating plate 110 is generally in a vertical state, so that the rotating shaft of the roller 130 is generally in a horizontal state, so that the support plate 210 pressed on the roller 130 is generally horizontal, facilitating the operation and movement of the furnace robot 400.

[0051] In addition, the distance between the limiting plate 140 and the roller 130 is slightly larger than the thickness of the support plate 210, so that the limiting plate 140 can also limit the support plate 210 to some extent, so that the support plate 210 is limited in the space above the roller 130 and below the limiting plate 140, so that the support plate 210 is kept as horizontal as possible, and the oxygen blowing position of the oxygen blowing pipe 310 is more easily controlled during movement.

[0052] It should be noted that in specific implementation, the limiting plate 140 can also be one, which is arranged on one rotating plate 110 and abuts against the other rotating plate 110, so that the limiting can also be achieved. The specific implementation of the limiting plate 140 is not limited here.

[0053] In some embodiments, as shown in Figure 6 , the two rotating plates 110 are symmetrically provided with guide wheels 150 on the side close to each other, and the rotating shaft of the guide wheel 150 is vertically arranged, and the guide wheel 150 is located below the limiting plate 140 and abuts against the side wall of the support plate 210. In this way, the two sides of the support plate 210 are abutted by the two guide wheels 150, and when the support plate 210 moves, the guide wheels 150 can guide the support plate 210 to some extent, avoiding the support plate 210 from being skewed, so that the moving position of the oxygen blowing pipe 310 is more accurate and the oxygen blowing position is more accurate.

[0054] It should be noted that the guide wheels 150 on each rotating plate 110 can be multiple, and the multiple guide wheels 150 are spaced apart along the length direction of the support plate 210, and abut and guide the support plate 210 from different positions in the length direction of the support plate 210.

[0055] In some embodiments, as shown in Figure 4As shown, the upper clamping member 220 includes an upper mounting cylinder 221, an upper cylinder cover 222, an upper spring 223, and an upper clamping plate 224. The upper mounting cylinder 221 is fixed to the lower surface of the support plate 210 with the cylinder opening facing downward. The upper cylinder cover 222 is provided with an upper through hole. The upper cylinder cover 222 covers the cylinder opening of the upper mounting cylinder 221. The upper spring 223 is arranged in the mounting cylinder. The upper clamping plate 224 is connected to the lower end of the upper spring 223. The upper clamping plate 224 is provided with an upper protruding block 225 which cooperates with the upper through hole. The upper protruding block 225 is provided with an upper clamping recess 226, so that the upper clamping plate 224 can be extended and retracted, and the upper protruding block 225 can extend out of the upper through hole.

[0056] Similarly, the lower clamping member 230 includes a lower mounting cylinder 231, a lower cylinder cover 232, a lower spring 233, and a lower clamping plate 234. One side of the lower mounting cylinder 231 is rotatably connected to the upper mounting cylinder 221. The other side of the lower mounting cylinder 231 is connected to the upper mounting cylinder 221 by a buckle (not shown in the figure). In this way, the lower clamping member 230 is mounted to the upper clamping member 220, and the buckle structure facilitates operation.

[0057] The lower cylinder cover 232 is provided with a lower through hole. The lower cylinder cover 232 covers the cylinder opening of the lower mounting cylinder 231. The lower spring 233 is arranged in the mounting cylinder. The lower clamping plate 234 is connected to the upper end of the lower spring 233. The lower clamping plate 234 is provided with a lower protruding block 235 which cooperates with the lower through hole. The lower protruding block 235 is provided with a lower clamping recess 236 which is opposite to the upper clamping recess 226. In this way, the lower clamping plate 234 can be extended and retracted, and the lower protruding block 235 can extend out of the lower through hole. The lower protruding block 235 cooperates with the upper protruding block 225. The space formed by the lower clamping recess 236 and the upper clamping recess 226 can clamp the oxygen blowing pipe 310.

[0058] In some embodiments, the upper clamping member 220 and the lower clamping member 230 are both multiple and one-to-one corresponding. The multiple upper clamping members 220 are arranged along the length direction of the support plate 210. The multiple lower clamping members 230 are also arranged along the length direction of the support plate 210. Figure 1 For example, four upper clamping members 220 and four lower clamping members 230 are illustrated. Of course, the lower clamping members 230 are also arranged along the length direction of the support plate 210. Since the length of the oxygen blowing pipe 310 is relatively long, generally about 6m, multiple upper clamping members 220 and lower clamping members 230 are used to clamp the oxygen blowing pipe 310 at multiple positions along the length direction of the oxygen blowing pipe 310. In this way, the oxygen blowing pipe 310 is clamped more firmly, and moves more stably and reduces shaking.

[0059] In some embodiments, the length of the support plate 210 is 4-6 m. When moving, the support plate 210 and the rollers 130 are in relative motion, and the support plate 210 cannot leave the rollers 130. The distance that the tapping robot 400 can move the oxygen blowing pipe 310 is related to the maximum length of the support plate 210. Therefore, the length of the support plate 210 should be able to meet the requirement that, as the oxygen blowing pipe 310 gradually shortens, the tapping robot 400 can still move the oxygen blowing pipe 310 to the tuyere to realize oxygen blowing to the tuyere. The length of the oxygen blowing pipe 310 is generally about 6 m, and the length of the support plate 210 is 4-6 m, which basically guarantees the movement of the oxygen blowing pipe 310.

[0060] Of course, for different lengths of the oxygen blowing pipe 310, the length of the support plate 210 can be adjusted accordingly, which will not be described in detail here.

[0061] In some embodiments, as shown in Figure 7 and Figure 8 , the oxygen blowing assembly 300 further comprises a support cylinder 320 and a sheath 330, the support cylinder 320 is used to install and support the oxygen blowing pipe 310, the number of the oxygen blowing pipe 310 is multiple, and the sheath 330 is wrapped on the outside of the multiple oxygen blowing pipes 310. In this way, the oxygen blowing assembly 300 comprises multiple oxygen blowing pipes 310, which increases the oxygen blowing area and improves the oxygen blowing efficiency. For example, Figure 8 shows that 7 oxygen blowing pipes 310 are wrapped by the sheath 330, so that the oxygen blowing area is increased by 7 times, and the oxygen blowing efficiency is greatly improved.

[0062] The sheath 330 is installed at the first end in the support cylinder 320, and the mechanical arm of the tapping robot 400 is clamped at the second end of the support cylinder 320, so that the overall clamping of the multiple oxygen blowing pipes 310 is realized.

[0063] In some embodiments, the length of the sheath 330 wrapped on the oxygen blowing pipe 310 is one-tenth to one-sixth of the length of the oxygen blowing pipe 310, that is, the sheath 330 only wraps a small part of the oxygen blowing pipe 310, which cannot be used for oxygen blowing, and when the oxygen blowing pipe 310 is shortened to the sheath 330, a new oxygen blowing pipe 310 should be replaced in time. The small part is firmly wrapped by the sheath 330, and the length does not need to be very long, generally, the wrapped length is one-tenth to one-sixth of the length of the oxygen blowing pipe 310. For example, when the length of the oxygen blowing pipe 310 is 6 m, the wrapped length is about 0.6-1 m, which can realize firm wrapping. In specific implementation, for different lengths of the oxygen blowing pipe 310, the length wrapped by the sheath 330 is about 0.5-1 m, which can realize firm wrapping.

[0064] In some embodiments, as shown in Figure 7As shown, the oxygen blowing assembly 300 also includes a cooling water jacket 340, which is fitted onto the sheath 330. Cooling water flows through the cooling water jacket 340 to cool the sheath 330. The oxygen blowing tube 310 is a consumable that shortens over time; it only needs to be replaced as oxygen blowing progresses. The sheath 330 is used to cover multiple oxygen blowing tubes 310, providing a fixing function, and is reusable. During oxygen blowing, the temperature of the oxygen blowing tube 310 is also transferred to the sheath 330, causing the temperature of the sheath 330 to rise and potentially leading to burning and shortening. Therefore, the cooling water jacket 340 is used to cool the sheath 330, preventing damage and extending its service life.

[0065] Generally, the inlet of the cooling water jacket 340 is located at the bottom, and the outlet is located at the top. This extends the time the cooling water spends within the cooling water jacket 340, thereby prolonging the heat exchange time and improving the cooling effect. Additionally, baffles can be installed inside the cooling water jacket 340 to restrict the direction of water flow, further extending the heat exchange time; however, this will not be discussed in detail here.

[0066] In some embodiments, such as Figure 7 As shown, the second end of the support cylinder 320 is provided with a clamping position 321 and a guide slope 322. The clamping position 321 is the position where the robotic arm of the unloading robot 400 clamps, and the guide slope 322 guides the robotic arm when clamping, making it easier to achieve the clamping of the robotic arm.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
