Description

Technical Field

[0001] This utility model belongs to the field of alumina recycling technology, and in particular relates to a highly stable alumina recycling device. Background Technology

[0002] Fiber ore, also known as fused alumina sand or ceramic sand, is a type of artificial foundry sand. Due to its advantages such as low thermal expansion, good fluidity, high refractoriness, low breakage rate, and good reusability, it is widely used in the production of high-end castings. In the process of using fiber ore, regeneration equipment is one of the important pieces of equipment, which is used to purify and regenerate the used fiber ore so that it can be reused. The existing patent announcement number CN219464682U discloses a multi-wheel grinding mill for recycling foundry waste sand, including a machine box with a feed inlet and a discharge outlet. Multiple parallel grinding wheels are arranged inside the machine box. A lead screw is arranged outside the machine box. A slider is rotatably connected to one end of the lead screw corresponding to the grinding wheel. A threaded sleeve is rotatably connected inside the slider. The threaded sleeve is threadedly connected to the lead screw. A fastening bolt is provided at the rotatable connection between the slider and the threaded sleeve. Tightening the fastening bolt can fix the slider and the threaded sleeve to rotate. Rotating the lead screw can make the slider and the grinding wheel slide along the lead screw. A drive assembly is arranged outside the machine box between the grinding wheel and the lead screw. The drive assembly can drive the grinding wheel to rotate. However, it still has the following drawbacks in practical use: The aforementioned regenerated multi-wheel sander adds abrasive sand into the machine casing through the feed inlet and regenerates the abrasive sand through the grinding wheels inside the machine casing. However, during use, after the abrasive sand is poured at high temperature, some sand particles will stick together due to surface melting. In addition, some inorganic binders on the surface of the sand particles have high hardness. The grinding wheels alone cannot regenerate the abrasive sand more efficiently and will lead to increased wear of the grinding wheels, which will reduce impact energy and efficiency, resulting in unstable regeneration effect. The aforementioned regenerated multi-wheel sander regenerates abrasive sand through grinding wheels inside the machine casing. However, during use, the fine powder and some of the binder powder generated during the regeneration process adhere to the surface of the grinding wheels, forming a buffer layer or contamination layer between the grinding wheels and the abrasive sand. This not only reduces the regeneration efficiency but also seriously deteriorates the regeneration quality.

[0003] To address these issues, we provide a highly stable abrasive sand regeneration device. Utility Model Content

[0004] The purpose of this invention is to provide a highly stable abrasive regeneration device. A preheating pipe preheats the abrasive raw material to be regenerated in the hopper, causing the inorganic binder on the abrasive surface to become brittle.

This solves the problem of existing devices that are difficult to remove hard deposits from the abrasive surface. Simultaneously, a lifting frame moves the scraper and air jet towards the grinding roller, and the scraper and air jet perform secondary cleaning of the grinding roller, solving the problem of existing devices that are inconvenient to clean the grinding roller during the regeneration process.

[0007] A further feature of this invention is that a second drive motor is fixedly connected to the bottom of the mixing chamber via a second motor frame, the output shaft of the second drive motor extends to the lower interior of the mixing chamber and is fixedly connected to a rotating shaft, and the top end of the rotating shaft extends to the interior of the connecting pipe and is fixedly connected to an auger rod.

[0008] A further feature of this invention is that a material collection hood is fixedly connected to the other side of the inner shell, and a discharge pipe is fixedly connected to the material collection hood. The end of the discharge pipe away from the material collection hood extends to the other side of the outer shell.

[0009] A further feature of this invention is that multiple second transmission gears are rotatably connected at equal intervals on both sides of the front end face of the hopper. The second transmission gears mesh between adjacent first driven gears on the left and right. Multiple third drive motors are fixedly connected to one side of the front end face of the hopper via a third motor frame. A second driving gear is fixedly connected to the output shaft of each of the third drive motors. The second driving gear meshes with the rightmost first driven gear.

[0010] The present invention is further configured such that: the front end of each grinding roller extends to the outside of the outer shell and is fixedly connected to a second driven gear; a first transmission gear is rotatably connected to both sides of the front end face of the outer shell; the first transmission gear meshes between two adjacent second driven gears; a first drive motor is fixedly connected to the top of the front end face of the outer shell via a first motor frame; a first drive gear is fixedly connected to the output shaft of the first drive motor; and the first drive gear meshes with the middle second driven gear.

[0011] A further feature of this invention is that: a first hydraulic cylinder is fixedly connected to both sides of the bottom of the outer casing; the output shaft of the first hydraulic cylinder extends into the interior of the outer casing and is fixedly connected to both sides of the bottom of the lifting frame located in the middle; L-shaped frames are fixedly connected at equal intervals to both sides of the interior of the outer casing; slide rods are fixedly connected to the bottom of the transverse support arms of the L-shaped frames; the bottom ends of the slide rods pass through both sides of the surface of the lifting frame and are fixedly connected to the bottom of the inner side of the outer casing.

[0014] This utility model has the following beneficial effects: This invention features a feeding assembly that opens the cover and adds crushed abrasive raw materials to the hopper. The cover is then closed, and the air inlet pipe is connected to the exhaust gas from the roasting furnace. This allows the high-temperature exhaust gas from the roasting furnace to be filtered and then flow into the preheating pipe, which preheats the abrasive raw materials in the hopper. This softens and brittles the binder on the abrasive surface, facilitating the subsequent peeling of the binder by the grinding rollers, thus improving the regeneration effect of the abrasive and making it easier to regenerate.

The output shaft of the first hydraulic cylinder drives a lifting frame, causing the lifting frame to rise along with the scraper and air jet pipe. When the scraper contacts the grinding roller, the first hydraulic cylinder is deactivated. The scraper initially peels off the adhesive or fine powder adhering to the outer surface of the grinding roller. Then, a high-pressure blower is connected to the air jet pipe, which provides high-pressure airflow to the grinding roller through a high-pressure nozzle. The impact and shearing force of the high-pressure airflow on the grinding roller achieves a secondary peeling off of the adhesive or fine powder adhering to the outer surface of the grinding roller. This reduces the amount of adhesive or fine powder adhering to the outer surface of the grinding roller, preventing excessive adhesive or fine powder from affecting the grinding effect on the granulated sand. This ensures the regeneration effect of the grinding roller on the granulated sand raw material, improves its regeneration stability, and facilitates the regeneration of granulated sand.

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this is the first embodiment of the present invention. This embodiment provides a high-stability abrasive regeneration device, including a shell 1. A feeding assembly 2 is provided on one side of the shell 1. The feeding assembly 2 includes a mixing box 201, a blower 202, a hopper 205, and a preheating pipe 206. The abrasive raw material to be regenerated in the hopper 205 is preheated by the preheating pipe 206, which makes the inorganic binder on the surface of the abrasive embrittled. The blower 202 sends the preheated raw material in the hopper 205 into the shell 1 for grinding and regeneration, which solves the problem of the existing abrasive surface hardness attachments being difficult to remove.

[0030] Specifically, a mixing chamber 201 is located on one side of the outer shell 1. A blower 202 is fixedly connected to the side of the mixing chamber 201 furthest from the outer shell 1. The mixing chamber 201 is used to mix the raw abrasive material to be regenerated with airflow. The airflow generated by the blower 202 sends the raw abrasive material to be regenerated from the mixing chamber 201 into the outer shell 1 for grinding and regeneration. A hopper 205 is fixedly connected above the mixing chamber 201. Multiple preheating pipes 206 are rotatably connected at equal intervals inside the hopper 205. The hopper 205 is used to store the raw abrasive material to be regenerated. The setting 6 is used to preheat the raw materials in hopper 205, making the binder soften, become brittle, and less tough, making it easier to peel off. Simultaneously, because the abrasive sand and the binder film attached to its surface have different coefficients of thermal expansion, heating causes the sand particles and the binder film to expand at different rates, thus generating thermal stress at their interface, leading to spontaneous cracking of the binder film or a decrease in its bonding force with the sand particles. The two ends of the preheating pipe 206 extend to the front and rear ends of the hopper 205 respectively and are connected to the air inlet pipe 206b and air outlet pipe 206c via rotary joints 206a. A first driven gear 206d is fixedly connected to the outer wall of hopper 205. The first driven gear 206d is located in front of the outside of hopper 205. The rotary joint 206a is used to connect preheating pipe 206, air inlet pipe 206b, and air outlet pipe 206c. The end of air inlet pipe 206b away from preheating pipe 206 is connected to the high-temperature exhaust gas of the roasting furnace, so that the filtered high-temperature exhaust gas of the roasting furnace enters the preheating pipe 206 through air inlet pipe 206b, realizing the recovery and reuse of waste heat of the roasting furnace, reducing energy loss and improving energy utilization. Air outlet pipe 206c... One end away from the preheating pipe 206 is connected to an external exhaust gas treatment device to treat and discharge the exhaust gas. The first driven gear 206d is used to drive the preheating pipe 206 to rotate. The centrifugal force generated by the rotation of the preheating pipe 206 causes the raw material attached to the preheating pipe 206 to be peeled off. Multiple grinding rollers 3 are rotatably connected at equal intervals inside the outer shell 1. The grinding rollers 3 are preferably made of high-temperature resistant metal. The friction, scraping force, impact force and shearing force generated by the high-speed rotation of the grinding rollers 3 are used to mechanically peel off the abrasive sand, thereby realizing the grinding and regeneration of the abrasive sand.

[0031] Furthermore, a cover plate 205a is movably connected to the top of the hopper 205. The cover plate 205a is designed to seal the interior of the hopper 205, enhancing the preheating effect of the preheating pipe 206 on the raw materials. A connecting pipe 205b is fixedly connected to the bottom of the hopper 205. The bottom end of the connecting pipe 205b extends to the upper part of the mixing chamber 201. The connecting pipe 205b is designed to connect the hopper 205 and the mixing chamber 201, allowing the raw materials in the hopper 205 to enter the mixing chamber 201 and mix with the airflow. A feed pipe 203 is fixedly connected to the outer wall of the outer shell 1. The end of the feed pipe 203 away from the mixing box 201 extends to the inner side of the outer shell 1 and is fixedly connected to the feed cover 204. The feed pipe 203 is used to connect the mixing box 201 and the outer shell 1, so that the raw material in the mixing box 201 can enter the outer shell 1. The feed cover 204 is used to evenly distribute the airflow in the mixing box 201 inside the outer shell 1, so that the airflow can evenly contact the grinding roller 3, ensuring the regeneration efficiency of the grinding roller 3 for the abrasive sand. The bottom of the mixing box 201 is fixedly connected to the second drive motor 201b via the second motor frame 201a. The output shaft of the second drive motor 201b extends to the lower interior of the mixing box 201 and is fixedly connected to the rotating shaft 201c. The top end of the rotating shaft 201c extends to the interior of the connecting pipe 205b and is fixedly connected to the auger rod 201d. The second motor frame 201a is set up to install the second drive motor 201b. The second drive motor 201b and the rotating shaft 201c are set up to install the auger rod 201d and drive the auger rod 201d to rotate. The auger rod 201d is set up to add the raw materials in the hopper 205 to the interior of the mixing box 201 in a quantitative manner. A material collection hood 105 is fixedly connected to the other side of the inner shell 1. A discharge pipe 106 is fixedly connected to the material collection hood 105. The end of the discharge pipe 106 away from the material collection hood 105 extends to the other side of the outer shell 1. The material collection hood 105 is set to collect the airflow inside the shell 1. The discharge pipe 106 is connected to an air classifier to screen the granulated abrasive raw material. Multiple second transmission gears 205c are rotatably connected at equal intervals on both sides of the front end face of the hopper 205. The second transmission gears 205c mesh between the adjacent first driven gears 206d on the left and right. The arrangement of the second transmission gears 205c enables the multiple first driven gears 206d on the same horizontal line to rotate synchronously, so that multiple preheating tubes 206 rotate synchronously. Multiple third drive motors 207 are fixedly connected to one side of the front end face of the hopper 205 through a third motor frame 207a. A second drive gear 207b is fixedly connected to the output shaft of each third drive motor 207. The second drive gear 207b meshes with the rightmost first driven gear 206d. The third drive motor 207 is used to drive the first driven gear 206d to rotate. The third motor frame 207a is used to install the third drive motor 207. The arrangement of the second drive gear 207b realizes the transmission connection between the third drive motor 207 and the first driven gear 206d. The front ends of the grinding rollers 3 extend to the outside of the housing 1 and are fixedly connected to the second driven gears 301. The front ends of the housing 1 are rotatably connected to the first transmission gears 101 on both sides. The first transmission gears 101 mesh between two adjacent second driven gears 301. The arrangement of the first transmission gears 101 enables multiple second driven gears 301 to rotate synchronously, so that multiple grinding rollers 3 rotate synchronously. The front ends of the housing 1 are fixedly connected to the first drive motor 103 via the first motor frame 102. The output shaft of the first drive motor 103 is fixedly connected to the first drive gear 104. The first drive gear 104 meshes with the middle second driven gear 301. The first motor frame 102 is used to install the first drive motor 103. The first drive motor 103 is used to drive the grinding rollers 3 to rotate. The arrangement of the first drive gear 104 and the second driven gears 301 realizes the transmission connection between the output shaft of the first drive motor 103 and the grinding rollers 3, so that the output shaft of the first drive motor 103 drives the grinding rollers 3 to rotate.

[0032] The operation process of this embodiment is as follows: First, open the cover plate 205a and add the crushed abrasive raw material to be recycled into the hopper 205. Close the cover plate 205a and connect the air inlet pipe 206b to the exhaust gas of the roasting furnace. This allows the high-temperature exhaust gas in the roasting furnace to flow into the preheating pipe 206 after filtration. The preheating pipe 206 preheats the abrasive raw material in the hopper 205, causing the binder on the surface of the abrasive to soften and become brittle. Then, start the second drive motor 201b. The output shaft of the second drive motor 201b drives the auger rod 201d to rotate through the rotating shaft 201c. The auger rod 201d adds a measured amount of raw material from the hopper 205 to the feed. Inside the mixing chamber 201, the blower 202 is started simultaneously. Under the action of the blower 202, the airflow carries the raw materials in the mixing chamber 201 into the outer shell 1 through the feed pipe 203 and the feed hood 204. Finally, the first drive motor 103 is started. The first drive motor 103 drives the grinding roller 3 to rotate through the first driving gear 104 and the second driven gear 301. With the help of the friction, scraping force, impact force and shearing force generated by the high-speed rotation of the grinding roller 3, the granulated sand is mechanically stripped by friction. The stripped granulated sand raw material enters the air classifier through the discharge pipe 106 for screening, realizing the grinding and regeneration of the granulated sand. Example 2

[0033] Please see Figure 2 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, this is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that a cleaning component 4 is provided below the grinding roller 3. The cleaning component 4 includes a lifting frame 401, a scraper 402, a collection frame 403, and an air jet pipe 404. The lifting frame 401 drives the scraper 402 and the air jet pipe 404 to move closer to the grinding roller 3, and the scraper 402 and the air jet pipe 404 perform secondary cleaning of the grinding roller 3, which solves the problem that it is inconvenient to clean the grinding roller 3 during the regeneration process.

[0034] Specifically, the lifting frame 401 has multiple scrapers 402 movably connected at equal intervals inside the lower part of the outer casing 1. The lifting frame 401 is used to install and move the scraper 402 and other structures, causing the scraper 402 to contact or separate from the grinding roller 3. Multiple scraper 402s are fixedly connected at equal intervals to the top of the lifting frame 401. The top of each scraper 402 abuts against the bottom of the grinding roller 3. The scraper 402s are used to initially scrape away the adhesive or fine powder adhering to the grinding roller 3, thus initially ensuring the cleanliness of the outer surface of the grinding roller 3 and preventing... The regeneration effect of the abrasive is affected by the adhesive or fine powder adhering to the outer surface of the grinding roller 3. A collection frame 403 is fixedly connected to one side of the outer wall of the scraper 402. The collection frame 403 is set to collect the adhesive or fine powder scraped off by the scraper 402. An air jet pipe 404 is also fixedly connected at equal intervals to the top of the scraper 402. The air jet pipe 404 is located on the side of the scraper 402 away from the collection frame 403. The high-pressure airflow sprayed by the air jet pipe 404 is used to perform secondary cleaning on the outer surface of the grinding roller 3, further ensuring the cleanliness of the outer surface of the grinding roller 3.

[0035] Furthermore, a first hydraulic cylinder 401a is fixedly connected to both sides of the bottom of the outer casing 1. The output shaft of the first hydraulic cylinder 401a extends into the interior of the outer casing 1 and is fixedly connected to both sides of the bottom of the lifting frame 401 located in the middle. The first hydraulic cylinder 401a is used to drive the lifting frame 401 to move up and down, so that the scraper 402 moves towards or away from the grinding roller 3. L-shaped frames 401b are fixedly connected at equal intervals to both sides of the interior of the outer casing 1. The bottom of the horizontal support arm of the L-shaped frame 401b is fixedly connected to a slide rod 401c. The bottom end of the slide rod 401c passes through both sides of the surface of the lifting frame 401 and is fixedly connected to the bottom of the inner side of the outer casing 1. The L-shaped frame 401b and the slide rod 401c are used to movably install the lifting frame 401 inside the outer casing 1. The bottom front and rear ends of the collection frame 403 are fixedly connected to the second hydraulic cylinder 403b through the U-shaped frame 403a. The output shaft of the second hydraulic cylinder 403b is fixedly connected to the L-shaped plate 403c. The horizontal support arm of the L-shaped plate 403c is attached to the top opening of the collection frame 403. The U-shaped frame 403a is set to install the second hydraulic cylinder 403b. The second hydraulic cylinder 403b is set to install the L-shaped plate 403c and drive the L-shaped plate 403c to move. The L-shaped plate 403c is set to close the interior of the collection frame 403. Multiple high-pressure nozzles 404a are fixedly connected to the jet pipe 404 at equal intervals. An expansion joint 404b is also fixedly connected to the jet pipe 404. The bottom end of the expansion joint 404b extends to the lower part of the outer shell 1. The high-pressure nozzles 404a are used to spray the high-pressure airflow in the jet pipe 404 onto the outer surface of the grinding roller 3. The expansion joint 404b is used to connect the jet pipe 404 to a high-pressure blower.

[0036] The rest of the structure is the same as in Example 1.

[0037] The operation process of this embodiment is as follows: The first hydraulic cylinder 401a is activated, and its output shaft drives the lifting frame 401 to move, causing the lifting frame 401 to lift the scraper 402 and the jet pipe 404. When the scraper 402 contacts the grinding roller 3, the first hydraulic cylinder 401a is closed. Then, the second hydraulic cylinder 403b is activated, and its output shaft drives the L-shaped plate 403c to move away from the collection frame 403. This allows the grinding roller 3 to rotate while the scraper 402 removes the adhesive residue adhering to its outer surface. The adhesive or fine powder is peeled off, and the peeled-off adhesive or fine powder falls into the collection frame 403 through the inclined surface on the scraper 402. Finally, the jet pipe 404 is connected to a high-pressure blower, so that the jet pipe 404 provides high-pressure airflow to the grinding roller 3 through the high-pressure nozzle 404a. Through the impact and shearing force of the high-pressure airflow on the grinding roller 3, the adhesive or fine powder attached to the outer surface of the grinding roller 3 is peeled off a second time, reducing the adhesive or fine powder attached to the outer surface of the grinding roller 3 and avoiding the grinding effect of the abrasive sand due to excessive adhesive or fine powder attached to the outer surface of the grinding roller 3.
