Description

Technical Field

[0001] This utility model relates to the field of powder recycling technology, specifically a powder recycling mechanism for sprue production. Background Technology

[0002] In the field of steelmaking nozzle production, nozzle production powder recycling institutions play a crucial role; however, such recycling institutions currently face some problems.

[0003] Traditional recycling facilities typically use fans to blow air into the tank, causing the powder to be collected along the bottom filter. However, in actual operation, powder easily adheres to the inner walls of the tank. Due to the fine particle size of steelmaking nozzle powder, it possesses a certain degree of stickiness and electrostatic adsorption. Under the disturbance of the fan airflow, a large amount of powder collides and adheres to the tank walls. Since the fan airflow is mainly directed towards the filter, it is difficult to effectively flush the inner walls, especially the corner areas, and thus cannot effectively clean the adhered powder. Over time, the amount of powder residue in the tank increases, not only taking up space but also potentially affecting the accuracy of subsequent recycling operations.

[0004] Meanwhile, the filter screen bears the crucial responsibility of preventing raw materials from passing through the chamber to ensure the purity of the recovered powder. During production, the raw materials are complex, including metallic materials such as alloy powders of iron, manganese, and silicon used to optimize the properties of molten steel; refractory materials such as alumina, silicon dioxide, and magnesia particles that withstand high-temperature molten steel corrosion; and slag-forming materials such as lime and fluorite. These raw materials are easily broken and scattered during processing. If they accumulate on the filter screen in large quantities, the effective filtration area will be significantly reduced, the mesh will become clogged, hindering powder discharge and significantly decreasing the discharge speed, thereby reducing the overall efficiency of the recycling system.

[0019] There are two square grooves, which are respectively opened at both ends of the scraper. The interior of the square groove is slidably inserted into the outer wall of the scraper.

[0020] Preferably, the inner wall cleaning mechanism includes:

[0021] There are four sets of arc-shaped grooves, which are respectively opened inside the box on the four sides.

[0022] Preferably, the inner wall cleaning mechanism includes:

[0024] Preferably, the inner wall cleaning mechanism includes:

[0025] A square groove is formed on the inner wall of the bottom of the arc-shaped groove. An inclined block is slidably inserted into the square groove. A spring is fixedly connected between the outer wall of the inclined block and the inner wall of the square groove.

[0026] Preferably, the collection mechanism includes:

[0027] A square shell is fixed to the bottom of the box body, and a collection box is detachably connected to one end of the square shell;

[0029] Fixing frame two is fixed to the bottom outer wall of the box body. The fixing frame two is fixedly connected to motor number two. The rotating shaft of motor number two is fixedly connected to a round rod. Cross two are fixedly connected to the outer walls of both ends of the round rod.

[0030] The filter screen frame is slidably inserted into the inner wall of the bottom discharge port of the box, and round blocks are fixedly connected to both outer walls of the filter screen frame.

[0031] Compared with the prior art, the beneficial effects of this utility model are:

[0032] 1.

The elastic push rod can make scraper blades 1 or 2 keep close to the inner wall of the box when moving, effectively improving the cleaning quality.

[0033] 2. By setting up an arc-shaped groove, scraper blades one and two can be driven to clean the inner wall of the box in one direction, avoiding the reciprocating motion of scraper blades one and two, which would push the powder to the top of the box and affect the quality of powder recovery. In addition, several inclined blocks are set inside the arc-shaped groove, which can make scraper blades one and two vibrate during the upward movement, causing the powder adhering to scraper blades one and two to fall off and avoid adhering to the inner wall of the box, effectively improving the quality of cleaning and recovery.

[0034] 3. The collection mechanism drives the filter screen frame to vibrate, which causes the raw materials falling on the filter screen frame to gather to one side and enter the collection box for collection. This prevents the raw materials from covering the feed inlet of the box directly on the filter screen frame, which would affect the recovery of powder and effectively improve the recovery efficiency and quality of powder.

Detailed Implementation

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Please see Figures 1-6In this embodiment of the utility model, a powder recycling mechanism for sprue production includes a collecting mechanism 100, which includes a housing 110 and the following parts: a fan 120 fixed to the top of the housing 110, and an inner wall cleaning mechanism 200 fixed inside the housing 110 to clean the powder adhering to the inner wall of the housing 110; and a collection mechanism 300 fixed to the bottom of the housing 110 to recycle the raw materials and fallen powder. The inner wall cleaning mechanism 200 includes the following parts: a fixing frame 210 fixed to the top wall of the housing 110; a first motor 211 fixedly connected to the outer wall of the fixing frame 210; and a threaded rod 212 fixedly connected to the shaft of the first motor 211. One end of the threaded rod 212 is rotatably connected to the fan 120 bracket. A cross 213 is screwed onto the outer wall of the threaded rod 212. Square rods 214 are fixedly connected to the outer wall of the bottom end of 213, and the outer wall of the square rods 214 is slidably inserted into the inner wall of the box 110. The elastic push rods 230 are fixed to one end of the square rods 214. There are two scrapers 231, which are fixed to the outer wall of one end of two elastic push rods 230 respectively. There are two scrapers 232, which are fixed to the outer wall of one end of the other two elastic push rods 230 respectively. There are two square grooves 233, which are opened at both ends of the scrapers 231 respectively. The inside of the square grooves 233 is slidably inserted into the outer wall of the scrapers 232. There are four sets of arc grooves 220, which are opened on the four sides of the box 110. By driving the No. 1 motor 211 to drive the cross 213 to move down, the scrapers 231 and 232 are pushed to move down along the inner wall of the box 110, which can effectively clean the dust attached to the inner wall.

[0044] The inner wall cleaning mechanism 200 includes the following parts: several inclined blocks 221 are provided and fixed at equal intervals on one side of the inner wall of the arc groove 220, and a square groove 222 is opened on the bottom inner wall of the arc groove 220. An inclined block 223 is slidably inserted inside the square groove 222. A spring 224 is fixedly connected between the outer wall of the inclined block 223 and the inner wall of the square groove 222. By providing the arc groove 220, scrapers 231 and 232 can be driven to clean the inner wall of the box 110 in one direction, avoiding the reciprocating motion of scrapers 231 and 232, which would cause the powder to be pushed to the top of the box 110 and affect the quality of powder recovery.

[0045] The collection mechanism 300 includes the following parts: its square shell 310 is fixed to the bottom of the box body 110; a collection box 311 is detachably connected to one end of the square shell 310; a collection box 320 is detachably connected to the bottom of the square shell 310; a fixing frame 330 is fixed to the outer wall of the bottom of the box body 110; a second motor 331 is fixedly connected to the fixing frame 330; and a round rod 332 is fixedly connected to the shaft of the second motor 331, with both ends of the round rod 332 fixedly connected to the outer wall. A crossbar 333 is attached, and its filter screen frame 334 is slidably inserted into the inner wall of the bottom discharge port of the box 110. Round blocks 335 are fixedly connected to the outer walls on both sides of the filter screen frame 334. The collection mechanism 300 drives the filter screen frame 334 to vibrate, which can cause the raw material falling on the filter screen frame 334 to gather to one side and enter the collection box 311 for collection, so as to avoid the raw material covering the position of the filter screen frame 334 directly opposite the discharge port of the box 110, which would affect the recovery of powder.

[0046] Specifically, during operation, the fan 120 above the housing 110 is first started to allow air to enter the housing 110, blowing the powder generated during the sprue production into the bottom of the housing 110. During operation, motor 211 drives the threaded rod 212 to rotate and engage with crossbar 213, causing crossbar 213 to move downwards. This causes square rod 214 to push scraper 231 or scraper 232 against the inner wall of the housing 110 and along the trajectory of the arc groove 220, cleaning the inner wall of the housing 110. After scraper 231 and scraper 232 push the dust to the bottom of the housing 110 along the trajectory of the arc groove 220, scraper 231 then moves downwards along the bottom trajectory of the arc groove 220. Scraper 1 and scraper 232 move towards the center of housing 110, moving scraper 1 231 and scraper 232 away from the inner wall of housing 110. When scraper 1 231 and scraper 232 contact inclined block 223, inclined block 223 is squeezed and slides into square groove 1 222. The rotating shaft of scraper 1 231 and scraper 232 will pass through inclined block 223. After separation, inclined block 223 will spring back to its original position under the influence of spring 224, blocking the path of arc groove 220 on one side of scraper 1 231 and scraper 232. At this time, motor 211 drives in the reverse direction to rotate threaded rod 212 and engage with cross 1 213, causing cross 1 213 to rise. Scraper 1 231 and scraper 232... 32, influenced by the elastic push rod 230, moves upward along one side of the outer wall of the inclined block 223. After separating from the inclined block 223, it moves upward along one side of the inner wall of the arc groove 220. When the rotating shafts of scraper 1 231 and scraper 232 pass the inclined block 221, they will move closely against the outer wall of the inclined block 221. When separating from the inclined block 221, influenced by the rebound of the elastic push rod 230, scraper 1 231 and scraper 232 quickly come into contact with the inner wall of the arc groove 220. The impact causes scraper 1 231 and scraper 232 to vibrate, shaking off the dust attached to scraper 1 231 and scraper 232. The powder will fall onto the filter screen frame 334 and pass through the filter screen frame 334 into the collection box below. Inside the second 320, the filter frame 334 can prevent the processed raw materials in the box 110 from passing through, and only the generated powder is recycled. When the filter frame 334 is covered with processed raw materials, the second motor 331 drives the round rod 332 to rotate, which drives the cross 333 to rotate and contact the round block 335. The round block 335 is squeezed and causes the filter frame 334 to slide along the inner wall of the discharge port of the box 110. When the cross 333 separates from the round block 335, the filter frame 334 will return to its original position. The repeated up and down movement can make the filter frame 334 continuously vibrate. During the process, the raw materials will move along the inclined surface of the filter frame 334 and slide into the collection box 311 for collection.

[0047] Example 1

[0048] like Figures 2-4As shown, in this embodiment, the inner wall cleaning mechanism 200 includes the following parts: its fixing frame 210 is fixed to the top wall of the housing 110; a motor 211 is fixedly connected to the outer wall of the fixing frame 210; a threaded rod 212 is fixedly connected to the shaft of the motor 211; one end of the threaded rod 212 is rotatably connected to the fan 120 bracket; a cross 213 is screwed onto the outer wall of the threaded rod 212; and square rods 214 are fixedly connected to the outer wall of the bottom end of the cross 213, with the outer wall of the square rods 214 being flush with the inner wall of the housing 110. The sliding connection is provided, with the elastic push rod 230 fixed to one end of the square rod 214, and two scraper blades 231 are provided, which are respectively fixed to the outer wall of one end of two elastic push rods 230. Two scraper blades 232 are provided, which are respectively fixed to the outer wall of one end of the other two elastic push rods 230. Two square grooves 233 are provided, which are respectively opened at both ends of scraper blade 231. The inside of square grooves 233 is slidably connected to the outer wall of scraper blade 232. Four sets of arc grooves 220 are provided, which are respectively opened inside the box 110 on the four sides.

[0049] In this embodiment, during operation, motor 211 drives threaded rod 212 to rotate and engage with crossbar 213, causing crossbar 213 to move downwards. This causes square rod 214 to push scraper 231 or scraper 232 against the inner wall of housing 110 and along the trajectory of arc groove 220, cleaning the inner wall of housing 110. By driving motor 211 to move crossbar 213 downwards, scraper 231 and scraper 232 are pushed against the inner wall of housing 110. The downward movement effectively cleans the dust adhering to the inner wall. The elastic push rod 230 ensures that scraper 1 231 or scraper 232 stays close to the inner wall of the housing 110 during movement, effectively improving cleaning quality. The arc groove 220 on the inner wall of the housing 110 effectively controls the movement path of scraper 1 231 and scraper 232, ensuring that scraper 1 231 and scraper 232 stay close to the inner wall of the housing 110 when moving downward, in conjunction with the elastic push rod 230, effectively improving working stability.

[0050] like Figures 3-5 As shown, in this embodiment, the inner wall cleaning mechanism 200 includes the following parts: a plurality of inclined blocks 221 are provided and fixed at equal intervals on one side of the inner wall of the arc groove 220, and a square groove 222 is opened on the bottom inner wall of the arc groove 220. An inclined block 223 is slidably inserted into the square groove 222, and a spring 224 is fixedly connected between the outer wall of the inclined block 223 and the inner wall of the square groove 222.

[0051] In practice, after scraper blade 1 231 and scraper blade 232 push the dust to the bottom of the housing 110 along the trajectory of the arc groove 220, they move towards the center of the housing 110 along the bottom trajectory of the arc groove 220, moving them away from the inner wall of the housing 110. When scraper blade 1 231 and scraper blade 232 come into contact with inclined block 223, inclined block 223 is squeezed and slides into the square groove 1 222. The pivot of scraper blade 1 231 and scraper blade 232 passes through inclined block 223, and after separation, inclined block 223 is subjected to spring... The effect of 224 will bounce back to its original position, blocking the path of the arc groove 220 on one side of scraper 1 231 and scraper 2 232. At this time, motor 211 drives the threaded rod 212 to rotate and engage with cross 1 213, causing cross 1 213 to rise. Scraper 1 231 and scraper 2 232 move upward along the outer wall of inclined block 2 223 under the influence of elastic push rod 230. After separating from inclined block 2 223, they move upward along the inner wall of the arc groove 220. When the rotating shaft of scraper 1 231 and scraper 2 232 passes inclined block 221, they will be in close contact with inclined block 221. As the outer wall moves, when it separates from the inclined block 221, the elastic push rod 230 rebounds, causing scrapers 231 and 232 to quickly contact the inner wall of the arc groove 220. The impact causes scrapers 231 and 232 to vibrate, shaking off the dust adhering to them. The arc groove 220 allows scrapers 231 and 232 to perform unidirectional cleaning of the inner wall of the housing 110, preventing reciprocating motion and the resulting push of powder to the top of the housing 110, which would affect the quality of powder recovery. Furthermore, several inclined blocks 221 are provided inside the arc-shaped groove 220, which can cause the scraper 231 and scraper 232 to vibrate during the upward process, causing the powder adhering to the scraper 231 and scraper 232 to fall off and avoid adhering to the inner wall of the box 110, effectively improving the cleaning and recycling quality. The inclined blocks 223 at the bottom of the arc-shaped groove 220 can slide to effectively control the movement trajectory of the scraper 231 and scraper 232, forcibly controlling the scraper 231 and scraper 232 to reciprocate along the trajectory of the arc-shaped groove 220, effectively improving the stability of the operation.

[0052] Example 2

[0053] like Figure 1 and Figure 6As shown, in this embodiment, the collection mechanism 300 includes the following parts: its square shell 310 is fixed to the bottom of the box body 110, a collection box 311 is detachably connected to one end of the square shell 310, a collection box 320 is detachably connected to the bottom of the square shell 310, and a fixing frame 330 is fixed to the bottom outer wall of the box body 110. A second motor 331 is fixedly connected to the fixing frame 330, and a round rod 332 is fixedly connected to the shaft of the second motor 331. Crosses 333 are fixedly connected to the outer walls of both ends of the round rod 332. The filter screen frame 334 is slidably inserted into the inner wall of the bottom discharge port of the box body 110, and round blocks 335 are fixedly connected to the outer walls on both sides of the filter screen frame 334.

[0054] In practice, the powder falls onto the filter screen frame 334 and passes through it into the lower collection box 320. The filter screen frame 334 prevents the processed raw materials in the box 110 from passing through, only recovering the generated powder. When the filter screen frame 334 is covered with processed raw materials, the second motor 331 drives the round rod 332 to rotate, causing the crossbar 333 to rotate and contact the round block 335. The round block 335 is squeezed, causing the filter screen frame 334 to slide along the inner wall of the discharge port of the box 110. When the crossbar 333 separates from the round block 335, the filter screen... The filter frame 334 will return to its original position. The repeated up-and-down movement causes the filter frame 334 to vibrate continuously. During this process, the raw material will move along the inclined surface of the filter frame 334 and slide into the collection box 311 for collection. The collection mechanism 300 drives the filter frame 334 to vibrate, which can cause the raw material falling on the filter frame 334 to gather to one side and enter the collection box 311 for collection. This avoids the raw material covering the feed port of the filter frame 334 directly opposite the box 110, which would affect the recovery of powder and effectively improve the recovery efficiency and quality of powder.
