Description

Technical Field

[0001] The invention belongs to the technical field of cannon mud transportation, in particular to a blast furnace iron mouth mud cannon machine with an automatic mud adding structure. Background Art

[0002] The blast furnace iron mouth mud gun machine is a key equipment used to quickly and accurately block the blast furnace iron mouth during blast furnace smelting. It is driven by hydraulic or mechanical means to push special gun mud to the blast furnace iron mouth for sealing to ensure the continuity and safety of blast furnace smelting. It is usually composed of a gun rotating mechanism, a gun pressing mechanism, a mud beating mechanism and a hydraulic system.

[0003] In the prior art, when the iron mouth needs to be sealed, the gun mud is put into the mud gun machine through the feed port. When the mud gun machine is full of gun mud, the gun nozzle is pushed toward the iron mouth of the blast furnace by a hydraulic cylinder or a mechanical drive device, and the gun mud is squeezed into the iron mouth. When the sealing is completed, the mud gun machine maintains pressure for a period of time to ensure that the gun mud can be fully sintered and solidified. Then the mud gun machine gradually withdraws from the iron mouth of the blast furnace and returns to its initial position.

[0004] There are still some problems in the actual application of the above scheme. The prepared gun mud is transported to the vicinity of the mud gun machine by a transfer cart. At this time, the staff opens the feed port of the mud gun machine and places the gun mud into the inner cavity of the mud gun machine by manual transportation. Since the amount of gun mud carried by manual labor each time is limited, frequent transportation operations are required, which will increase the labor intensity of the staff and thus reduce work efficiency. At the same time, during the filling process, since the gun mud is a non-fluid material, a large amount of accumulation will be generated at the feeding port, which will cause the feeding channel to be blocked, resulting in the mud gun machine being unable to normally fill the gun mud, thereby affecting the efficiency of the entire production process.

[0005] To this end, the present invention provides a blast furnace iron mouth mud gun machine with an automatic mud adding structure. Summary of the invention

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Embodiment 1

[0034] like Figures 1 to 8 As shown, a blast furnace iron mouth mud gun machine with an automatic mud adding structure described in an embodiment of the present invention includes a mud gun machine body 1, and the mud gun machine body 1 includes a support platform 101, a first fixed column 102 is fixedly connected to the upper part of the support platform 101, a first hydraulic cylinder 103 is rotatably arranged above the first fixed column 102, a first motor 104 is fixedly arranged on the upper part of the support platform 101, a rotating arm 105 is fixedly connected to the output shaft of the first motor 104, and the outer annular surface of the rotating arm 105 away from one end of the first motor 104 is fixedly connected to the support plate 10 6. The first hydraulic cylinder 103 is rotatably arranged in the middle of the support plate 106, and a second hydraulic cylinder 107 is fixedly arranged at the lower part of the rotating arm 105 away from one end of the first motor 104, and a storage barrel 108 is fixedly connected to the side of the second hydraulic cylinder 107, and a feeding port 109 is provided on the outer ring surface of the storage barrel 108, and a discharge port 110 is fixedly connected to the other end of the storage barrel 108, and an arc-shaped opening is provided on the outer ring surface of the storage barrel 108, and a groove is provided on the side of the arc-shaped opening of the storage barrel 108, and a reciprocating feeding mechanism 2 is provided on the outer ring surface of the mud gun machine body 1.

[0035] Specifically, since the mud gun machine is located near the iron outlet of the blast furnace, the temperature is high and a large amount of dust is generated during the iron-making process of the blast furnace. This dust not only affects the vision, but also contains toxic and harmful substances. In such an environment, workers filling the gun mud will cause damage to their respiratory system. Long-term exposure may also lead to occupational diseases such as pneumoconiosis. At the same time, due to the extremely high temperature, workers working in such an environment are prone to heatstroke and burns, and even cause more serious safety accidents.

[0036] Therefore, the present invention solves this problem by setting a corresponding structure. The blast furnace iron mouth mud gun machine with an automatic mud adding structure described in the present invention will be transported to the feed port 109 by the staff's mobile phone during the feeding process, so that the gun mud falls into the storage barrel 108 through the feed port 109. At this time, the first motor 104 is started to make the rotating arm 105 rotate around the first motor 104. When it rotates to the specified position, the discharge port 110 needs to be aligned with the iron outlet. At this time, the second hydraulic cylinder 107 is started to push the gun mud in the storage barrel 108 to the discharge port 110, and the iron outlet is blocked through the discharge port 110. However Since the mud gun machine is located near the iron outlet of the blast furnace, the temperature is relatively high and a large amount of dust will be generated during the iron-making process of the blast furnace. These dusts will not only affect the line of sight, but also contain toxic and harmful substances. In such an environment, the workers will cause damage to their respiratory system when filling the gun mud. Long-term exposure may also lead to occupational diseases such as pneumoconiosis. At this time, the movement of the reciprocating pushing mechanism 3 can achieve the purpose of automatic feeding, thereby reducing the direct contact between the workers and the gun mud dust and reducing the risk of occupational diseases such as pneumoconiosis. At the same time, the use of mechanical equipment can prevent the workers from being directly exposed to high temperature environments and reduce the risks of heat stroke, burns, etc.

[0037] Embodiment 2

[0038] like Figures 1 to 8 As shown in Comparative Example 1, another embodiment of the present invention is:

[0039] like Figure 6 As shown, in this embodiment, a protective shell 212 is fixedly connected to the bottom of the first moving rod 207, a second motor 211 is fixedly provided on the side of the protective shell 212, and a bidirectional screw 213 is fixedly connected to the output shaft of the second motor 211.

[0040] Specifically, when the iron mouth needs to be sealed, the second motor 211 fixedly arranged on the side of the protective shell 212 is started. When the second motor 211 is started, the bidirectional screw 213 fixedly connected to its output shaft will rotate synchronously. Since the outer ring surface of the bidirectional screw 213 is a bidirectional thread setting, the rotation of the bidirectional screw 213 can drive the two groups of components to move synchronously.

[0041] like Figure 6 As shown, the outer surface of the bidirectional screw 213 in this embodiment is threadedly connected with a moving ring 214.

[0042] like Figure 6 As shown, in this embodiment, the outer ring surface of the moving ring 214 is fixedly connected to a second moving rod 215 , and one end of the second moving rod 215 away from the moving ring 214 is fixedly connected to a clamping plate 216 .

[0043] Specifically, when the bidirectional screw 213 rotates, it will drive the two groups of moving rings 214 threadedly connected to its outer ring surface to move synchronously. Since the two groups of second moving rods 215 are respectively fixedly connected to the outer ring surfaces of the two groups of moving rings 214, when the two groups of moving rings 214 rotate, the two groups of second moving rods 215 will be driven to move synchronously, and then the clamping plates 216 fixed at the bottom of the two groups of second moving rods 215 will be driven to move synchronously.

[0044] like Figure 6 As shown, in this embodiment, a limiting groove 217 is provided at the bottom of the protective shell 212 , and the second moving rod 215 is slidably connected in the limiting groove 217 .

[0045] Specifically, when the two groups of second moving rods 215 drive the two groups of clamping plates 216 to move synchronously, since the two groups of second moving rods 215 slide inside the limiting groove 217, when the moving ring 214 drives the second moving rods 215 to move synchronously, they will move in a straight line due to the influence of the limiting groove 217. At the same time, due to the rotation of the bidirectional screw 213, the two groups of clamping plates 216 will move in a relative straight line, so as to clamp the gun mud placed on the material rack.

[0046] like Figure 3 As shown, the reciprocating feeding mechanism 2 of this embodiment includes a protection frame 201 , which is fixedly connected to the outer annular surface of the storage barrel 108 , and a second fixing column 202 is fixedly connected to the lower part of the inner cavity of the protection frame 201 .

[0047] like Figure 3 and Figure 4 As shown, in this embodiment, an electric telescopic rod 203 is rotatably provided on the outer annular surface of one end of the second fixed column 202 away from the inner cavity of the protection frame 201, and a rectangular block 204 is fixedly connected to the end of the electric telescopic rod 203 away from the second fixed column 202. A movable column 205 is provided in the middle of the rectangular block 204, and the rectangular block 204 is rotatably connected to the outer annular surface of the movable column 205.

[0048] Specifically, when the two groups of clamping plates 216 clamp the cannon mud, the electric telescopic rod 203 is started, and the electric telescopic rod 203 will extend, while pushing the rectangular block 204 fixed at one end of the electric telescopic rod 203 away from the second fixed column 202 to move synchronously. When the rectangular block 204 moves, it will drive the movable column 205 connected to its middle rotation to move synchronously, thereby providing power support for the movement of subsequent devices.

[0049] like Figure 4 and Figure 5As shown, in this embodiment, an L-shaped frame 206 is fixedly connected to the upper middle part of the inner cavity of the protection frame 201, and a first moving rod 207 is slidably connected inside the L-shaped frame 206. The moving column 205 is fixedly connected to the side of the first moving rod 207, and a first guide groove 208 is opened on the side of the L-shaped frame 206. The first guide groove 208 consists of a vertical groove and a horizontal groove, and the moving column 205 is slidably connected in the first guide groove 208.

[0050] Specifically, when the rectangular block 204 drives the moving column 205 to move, it will drive the first moving rod 207 sliding inside the L-shaped frame 206 to move synchronously. Since the moving column 205 slides in the first guide groove 208 opened on the side of the L-shaped frame 206, when the moving column 205 moves, it will be guided by the vertical groove of the first guide groove 208 to move in a straight line. The guidance of the vertical groove of the first guide groove 208 can facilitate the two sets of clamping plates 216 to clamp the gun mud and lift it at the same time.

[0051] like Figure 4 and Figure 5 As shown, in this embodiment, the first moving rod 207 is fixedly connected to a rotating column 209 on the side away from the moving column 205, and a second guide groove 210 is provided on the outer ring surface of the rotating column 209. The rotating column 209 is slidably connected inside the second guide groove 210, and the second guide groove 210 is opened on the side of the L-shaped frame 206 away from the first guide groove 208.

[0052] Specifically, when the first moving rod 207 moves, it will drive the rotating column 209 fixed on its side to be lifted synchronously, and in the process of lifting, it will fit with the inner ring surface of the circular hole at the junction of the vertical groove and the horizontal groove of the second guide groove 210, and the top of the first moving rod 207 and the top of the inner cavity of the L-shaped frame 206 still maintain a corresponding distance. However, since the electric telescopic rod 203 is still in the extension stage, the first moving rod 207 will drive the protective shell 212 and the other components directly connected to the protective shell 212 to rotate around the rotating column 209. When the first moving rod 207 rotates to the first When the transverse grooves of the guide grooves 208 are parallel, the first moving rod 207 will move horizontally in a straight line along the guide of the first guide groove 208 and the transverse grooves of the second guide grooves 210 under the drive of the electric telescopic rod 203. When the rotating column 209 fixed on the side of the first moving rod 207 moves to one end of the transverse groove of the second guide groove 210 close to the storage barrel 108, the second motor 211 is started to drive the bidirectional screw 213 to rotate in the opposite direction, thereby sending the clamped gun mud into the storage barrel 108, thereby reducing the fatigue of workers during long-term high-intensity work, and reducing the decline in work efficiency and the risk of safety accidents caused by fatigue.

[0053] like Figure 8As shown, the mud gun machine body 1 described in this embodiment is internally provided with a reciprocating pushing mechanism 3 for pushing materials, and the reciprocating pushing mechanism 3 includes a fixed plate 301, and the fixed plate 301 is slidably connected in an arc-shaped groove opened on the outer ring surface of the storage barrel 108, and an oblique clamping block 302 is fixedly connected to the upper part of the fixed plate 301, and the bottom of the oblique clamping block 302 is adapted to the curvature of the outer ring surface of the storage barrel 108, and an electric cylinder 303 is fixedly provided at the lower part of the fixed plate 301, and the electric cylinder 303 is composed of a cylinder body and a telescopic rod, and the end of the telescopic rod of the electric cylinder 303 away from the cylinder body is fixedly connected to a push plate 304.

[0054] Specifically, when the reciprocating feeding mechanism 2 is performing automatic feeding, the reciprocating pushing mechanism 3 is manually slid toward the inside of the storage barrel 108 along the arc-shaped groove opened on the outer ring surface of the storage barrel 108. When the bottom of the fixed oblique block 302 on the upper part of the fixed plate 301 is in contact with the outer ring surface of the storage barrel 108, the electric cylinder 303 is started. At this time, the electric cylinder 303 will push the telescopic rod sliding inside it to move away from the fixed plate 301, and simultaneously drive the pushing plate 304 fixed at the other end of the telescopic rod of the electric cylinder 303 to move synchronously. Through the movement of the pushing plate 304, the gun mud can be quickly pushed into the inside of the mud gun machine from the feeding port, reducing the waiting time of manual operation, thereby speeding up the production rhythm and improving work efficiency.

[0055] Working principle: when the iron mouth needs to be sealed, the second motor 211 fixedly arranged on the side of the protective shell 212 is started. When the second motor 211 is started, the bidirectional screw 213 fixedly connected to its output shaft will rotate synchronously. Since the outer ring surface of the bidirectional screw 213 is a bidirectional thread setting, the rotation of the bidirectional screw 213 can drive the two groups of components to move synchronously.

[0056] When the bidirectional screw 213 rotates, it will drive the two groups of moving rings 214 threadedly connected to its outer ring surface to move synchronously. Since the two groups of second moving rods 215 are respectively fixedly connected to the outer ring surfaces of the two groups of moving rings 214, when the two groups of moving rings 214 rotate, the two groups of second moving rods 215 will be driven to move synchronously, and then the clamping plates 216 fixed at the bottom of the two groups of second moving rods 215 will be driven to move synchronously.

[0057] When the two groups of second moving rods 215 drive the two groups of clamping plates 216 to move synchronously, since the two groups of second moving rods 215 slide inside the limiting groove 217, when the moving ring 214 drives the second moving rods 215 to move synchronously, they will move in a straight line due to the influence of the limiting groove 217. At the same time, due to the rotation of the bidirectional screw 213, the two groups of clamping plates 216 will move in a relative straight line, so as to clamp the gun mud placed on the material rack.

[0058] When the two sets of clamping plates 216 clamp the cannon mud, the electric telescopic rod 203 is started, and the electric telescopic rod 203 will extend, and at the same time, the rectangular block 204 fixed on the end of the electric telescopic rod 203 away from the second fixed column 202 will be pushed to move synchronously. When the rectangular block 204 moves, it will drive the movable column 205 connected to its middle rotation to move synchronously, thereby providing power support for the movement of subsequent devices.

[0059] When the rectangular block 204 drives the moving column 205 to move, it will drive the first moving rod 207 sliding inside the L-shaped frame 206 to move synchronously. Since the moving column 205 slides in the first guide groove 208 opened on the side of the L-shaped frame 206, the moving column 205 will be guided by the vertical groove of the first guide groove 208 to move in a straight line when it moves. The guidance of the vertical groove of the first guide groove 208 can facilitate the two sets of clamping plates 216 to clamp the gun mud and lift it at the same time.

[0060] When the first moving rod 207 moves, it will drive the rotating column 209 fixed on its side to be lifted synchronously, and in the process of lifting, it will fit with the inner ring surface of the circular hole at the junction of the vertical groove and the horizontal groove of the second guide groove 210, and the top of the first moving rod 207 and the top of the inner cavity of the L-shaped frame 206 still maintain a corresponding distance. However, since the electric telescopic rod 203 is still in the extension stage, the first moving rod 207 will drive the protective shell 212 and the other parts directly connected to the protective shell 212 to rotate around the rotating column 209. When the first moving rod 207 rotates to the first guide groove 210, the first moving rod 207 will rotate to the first guide groove 210. When the transverse grooves 208 are parallel, the first moving rod 207 will move horizontally in a straight line along the guidance of the first guide groove 208 and the second guide groove 210 transverse grooves under the drive of the electric telescopic rod 203. When the rotating column 209 fixed on the side of the first moving rod 207 moves to one end of the transverse groove of the second guide groove 210 close to the storage barrel 108, the second motor 211 is started to drive the bidirectional screw 213 to rotate in the opposite direction, thereby sending the clamped gun mud into the storage barrel 108, thereby reducing the fatigue of workers during long-term high-intensity work, and reducing the decline in work efficiency and the risk of safety accidents caused by fatigue.

[0061] When the reciprocating feeding mechanism 2 is performing automatic feeding, the reciprocating pushing mechanism 3 is manually slid toward the inside of the storage barrel 108 along the arc-shaped groove on the outer ring surface of the storage barrel 108. When the bottom of the fixed oblique block 302 on the upper part of the fixed plate 301 fits with the outer ring surface of the storage barrel 108, the electric cylinder 303 is started. At this time, the electric cylinder 303 will push the telescopic rod sliding inside it to move away from the fixed plate 301, and simultaneously drive the pushing plate 304 fixed at the other end of the telescopic rod of the electric cylinder 303 to move synchronously. Through the movement of the pushing plate 304, the gun mud can be quickly pushed into the inside of the mud gun machine from the feeding port, reducing the waiting time of manual operation, thereby speeding up the production rhythm and improving work efficiency.

[0062] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
