Description

Technical Field

[0001] The utility model relates to the technical field of impurity removing devices, in particular to an impurity removing device during the smelting of brass strips. Background Art

[0002] Brass strip has extremely good plasticity (the best among brasses) and high strength, good machinability, easy welding, and very stable to general corrosion, but prone to corrosion cracking. Brass strip is an alloy of copper and zinc, named for its yellow color. Smelting refers to melting solid metal into liquid in a heating furnace and tempering it, which is one of the casting production processes.

[0003] Many impurities will be generated during the smelting process of brass strips. If they are not removed in time, the product quality will be affected. Currently, most workers stand next to the smelting furnace and use a slag shovel to remove the impurities in the smelting furnace. Since the temperature of the brass solution in the smelting furnace is extremely high, it is easy for the workers to be scalded. Utility Model Content

Due to the extremely high temperature of the brass solution in the smelting furnace, the staff may be easily scalded.

When the movable plate and the fixed plate clamp the impurities, the limit plate can be rotated to make it horizontal, which can support the impurities.

Therefore, when the movable plate rotates toward the front of the fixed plate, it will drive the first bevel gear to rotate counterclockwise, and then drive the second bevel gear to rotate, and further drive the limit plate to rotate. The circumference of the second bevel gear is three to four times that of the first bevel gear. When the movable plate is rotated to clamp the impurities with the fixed plate, the limit plate rotates to a nearly horizontal position. When unloading, the movable plate is rotated in the opposite direction, which can drive the limit plate to rotate in a vertical state, making the operation more convenient, thereby avoiding the situation where most of the staff currently stand next to the smelting furnace and hold a slag shovel to remove impurities in the smelting furnace. Due to the extremely high temperature of the brass solution in the smelting furnace, the staff may be scalded. BRIEF DESCRIPTION OF THE DRAWINGS

Then start the first motor 36. The output shaft of the first motor 36 drives the movable plate 34 to rotate. During the rotation of the movable plate 34, the impurities in the smelting furnace 2 are pushed forward. The movable plate 34 rotates from the back of the fixed plate 35 to the front of the fixed plate 35. The movable plate 34 and the fixed plate 35 clamp the impurities, and then the hydraulic cylinder 31 is started. The hydraulic cylinder 31 drives the rectangular plate 32 to rise so that the impurities leave the smelting furnace 2, thereby avoiding the situation that most workers currently stand next to the smelting furnace 2 and use a slag shovel to fish out the impurities in the smelting furnace 2. Due to the extremely high temperature of the brass solution in the smelting furnace 2, the workers are easily scalded. The fixed plate 35 is rotatably connected to the limit plate 37. A number of circular holes are opened on the movable plate 34, the fixed plate 35 and the limit plate 37. When the movable plate 34 and the fixed plate 35 clamp the impurities, the limit plate 37 can be rotated to make it water-soluble. The bottom plate 1 is in a flat state, which can support impurities. A card slot 311 is provided on the bottom plate 1, and a collection box 310 is clamped in the card slot 311. After the impurities are clamped, the hydraulic cylinder 31 is rotated so that the rectangular plate 32 drives the fixed plate 35 to move above the collection box 310, and then the limit plate 37 is rotated to a vertical state, and the movable plate 34 is rotated to the back of the fixed plate 35, so that the impurities can be loosened and fall into the collection box 310, and the collection box 310 can take out the card slot 311, which is convenient for handling impurities. A mounting plate 314 is fixedly connected to the bottom plate 1, and a second motor 313 is fixedly connected to the mounting plate 314. A flat gear 312 is fixedly connected to the output shaft of the second motor 313, and a flat gear 312 is fixedly connected to the hydraulic cylinder 31.

One end of the rotating rod 33 is fixedly connected to the first bevel gear 38, and the second bevel gear 39 is fixedly connected to the limiting plate 37. The first bevel gear 38 is meshed with the second bevel gear 39. When the movable plate 34 is located at the back of the fixed plate 35, the limiting plate 37 is in a vertical downward state. Therefore, when the movable plate 34 rotates toward the front of the fixed plate 35, it will drive the first bevel gear 38 to rotate counterclockwise, thereby driving the second bevel gear 39 to rotate, and further driving the limiting plate 37 to rotate.The circumference of the second bevel gear 39 is three to four times that of the first bevel gear 38. When the movable plate 34 rotates to clamp the impurities with the fixed plate 35, the limit plate 37 rotates to a nearly horizontal position. When unloading, the movable plate 34 rotates in the opposite direction to drive the limit plate 37 to rotate to a vertical state, making the operation more convenient.

[0029] Reference Figure 2 A cleaning structure 4 is provided on the bottom plate 1. The cleaning structure 4 is mainly composed of a fixed rod 41. The fixed rod 41 is fixedly connected to the bottom plate 1. A sliding plate 42 is provided on the fixed rod 41. One end of the sliding plate 42 is rotatably connected to a steel brush 43. When impurities fall into the collection box 310, the hydraulic cylinder 31 continues to rotate the steel brush 43 to abut against the fixed plate 35 and the limit plate 37, and the steel brush 43 is driven to rotate under the action of friction to clean the through holes on the fixed plate 35 and the limit plate 37 to prevent the through holes from being blocked. A fixed block 44 is fixedly connected to the fixed rod 41. The fixed block 44 is provided with The slide groove 45 is slidably connected with the sliding plate 42. The sliding plate 42 can be slid to adjust the position of the steel brush 43 so that the steel brush 43 is always in contact with the fixed plate 35 and the limit plate 37 to improve the cleaning effect. A spring 46 is fixedly connected to the sliding plate 42, and one end of the spring 46 is fixedly connected to the inner wall of the slide groove 45. When the steel brush 43 cleans the through hole, the spring 46 is in a contracted state, so the rebound force of the spring 46 acts on the sliding plate 42, so that the steel brush 43 is always in contact with the fixed plate 35 and the limit plate 37. There is no need to manually slide the sliding plate 42, making the operation more convenient.

[0030] Working principle: start the hydraulic cylinder 31, so that the hydraulic cylinder 31 drives the rectangular plate 32 to descend until the fixed plate 35 extends into the smelting furnace 2, and then start the first motor 36. The output shaft of the first motor 36 drives the movable plate 34 to rotate. During the rotation of the movable plate 34, the impurities in the smelting furnace 2 are pushed forward. The movable plate 34 rotates from the back of the fixed plate 35 to the front of the fixed plate 35. The movable plate 34 and the fixed plate 35 clamp the impurities. Then start the hydraulic cylinder 31, and the hydraulic cylinder 31 drives the rectangular plate 32 to rise so that the impurities leave the smelting furnace 2, thereby avoiding the current situation that most of the staff stand next to the smelting furnace 2 and hold the slag shovel to remove the impurities in the smelting furnace 2. Due to the extremely high temperature of the brass solution in the smelting furnace 2, the impurities in the smelting furnace 2 are removed. The movable plate 34 and the fixed plate 35 are arranged to clamp the impurities, and the limit plate 37 can be rotated to make it horizontal, which can support the impurities. After the impurities are clamped, the hydraulic cylinder 31 is rotated so that the rectangular plate 32 drives the fixed plate 35 to move above the collection box 310, and then the limit plate 37 is rotated to a vertical state. The movable plate 34 is rotated to the back of the fixed plate 35 to loosen the impurities and make them fall into the collection box 310, and the collection box 310 can take out the card slot 311, which is convenient for handling impurities. The second motor 313 is started, and the output shaft of the second motor 313 drives a flat gear 312 to rotate, thereby driving another second motor 313 to rotate in the opposite direction. When the movable plate 34 is located at the back of the fixed plate 35, the limit plate 37 is in a vertical downward state. Therefore, when the movable plate 34 is rotated toward the front of the fixed plate 35, the first bevel gear 38 is driven to rotate counterclockwise, thereby driving the second bevel gear 39 to rotate, and further driving the limit plate 37 to rotate. The circumference of the second bevel gear 39 is three to four times that of the first bevel gear 38. When the movable plate 34 is rotated to clamp the impurities with the fixed plate 35, the limit plate 37 is rotated to a nearly horizontal position. When unloading, the movable plate 34 is rotated in the opposite direction, which can drive the limit plate 37 to rotate to a vertical state, making the operation more convenient and safer. The operation is more convenient. When impurities fall into the collection box 310, the hydraulic cylinder 31 continues to rotate the steel brush 43 to resist the fixed plate 35 and the limit plate 37, and the friction force drives the steel brush 43 to rotate, so as to clean the through holes on the fixed plate 35 and the limit plate 37, and prevent the through holes from being blocked. The sliding plate 42 can be slid to adjust the position of the steel brush 43, so that the steel brush 43 is always in contact with the fixed plate 35 and the limit plate 37, thereby improving the cleaning effect. When the steel brush 43 cleans the through holes, the spring 46 is in a contracted state, so the rebound force of the spring 46 acts on the sliding plate 42, so that the steel brush 43 is always in contact with the fixed plate 35 and the limit plate 37, and there is no need to manually slide the sliding plate 42, thereby making the operation more convenient.
