Description

Technical Field

[0001] The invention relates to the technical field of molding sand recovery devices, and in particular to a waste recycling device and method suitable for metal casting. Background Art

[0002] The waste recycling device for metal casting is mainly used in foundries to recycle, process and reuse the waste sand (i.e. used molding sand) generated during the casting process. The main purpose of this device is to improve the utilization rate of sand, reduce costs and reduce environmental pollution. The main working step of molding sand recycling is to crush the used molding sand mold so that the molding sand can be used again to make new molds. This device is widely used in foundries, machinery manufacturers and other enterprises that need to use a large amount of molding sand. Through this device, enterprises can significantly reduce the cost of raw materials, improve production efficiency, and reduce the pollution of waste sand to the environment.

[0003] The existing recycling device includes a double-roll crusher, which crushes the molding sand blocks by two rolling rollers. However, metal impurities will remain in the used molding sand molds. When the metal impurities enter between the two rolling rollers, if the metal impurities are larger than the gap between the two rolling rollers, the rolling rollers will forcibly crush the metal impurities, causing damage to the rolling rollers, reducing the service life of the device and reducing the effect of crushing the molding sand.

[0034] A method for recycling waste suitable for metal casting, based on the above-mentioned waste recycling device suitable for metal casting, specifically comprises the following steps:

[0035] S1: When using the device, first place the device at the work site, rotate the threaded rod to adjust the distance between the sliding bar and the sliding frame, thereby changing the initial elastic force of the second spring between the two;

[0036] S2: Turn on the power supply to start the power part, which drives the two rolling rollers to rotate. The waste is crushed by the two rolling rollers, and then falls onto the guide plate, slides along the guide plate into the first discharge port and is discharged;

[0037] S3: When the power part is started, the circulating cooling device is started at the same time, and cooling water enters the rolling roller, thereby taking away the heat of the rolling roller, and then returns from the rolling roller to the circulating cooling device to cool the cooling water;

[0038] S4: When large pieces of metal are mixed in the waste, the two rolling rollers squeeze the metal and move it downward, the rolling rollers on the sliding frame are squeezed, the sliding frame drives the sliding plate to move, and the sliding plate drives the guide plate to rotate, so that the metal falls into the second discharge port along the guide plate;

[0039] S5: After the metal passes through the two rolling rollers, the sliding frame is reset under the action of the first spring, and at the same time, the sliding frame drives the sliding plate to reset, and the sliding plate drives the guide plate to reset, so as to continue to crush the waste;

[0040] S6: When the temperature of the rolling roller changes, the volume of the thermally expanded gas in the gas storage shell changes, so that the transmission gate moves, so that the temperature of the rolling roller is controlled within the normal working range;

[0041] S7: When the waste between the two rolling rollers is blocked and cannot be discharged smoothly, the gate moves downward until the upper side of the gate is lower than the water inlet, so that the water pressure acts on the fourth sliding member, causing the fourth sliding member to drive the two rolling rollers to separate, thereby discharging the accumulated waste, and the sliding frame drives the guide plate to rotate, and then the sliding frame is reset under the action of the first spring, and the guide plate and the fourth sliding member are driven to reset;

[0042] S8: When the work is completed, turn off the power supply, and the power parts and circulating cooling device stop working.

[0043] Compared with the prior art, the present invention has the following advantages: when a large piece of metal impurities passes between the two rolling rollers, the present invention moves one of the rolling rollers, thereby avoiding damage caused by the two rolling rollers squeezing the metal impurities, thereby improving the service life of the device, and using the power of the movement of one of the rolling rollers to rotate the guide plate to change the position where the metal impurities fall, thereby reducing the content of metal impurities in the recovered molding sand and improving the purity of the molding sand recovered and reused by the device.

[0044] According to the hardness of the molding sand, the threaded rod is rotated to adjust the elastic force of the second spring between the sliding frame and the sliding bar, so as to distinguish the molding sand from large pieces of metal impurities.

[0045] By passing water through the rolling roller, the roller is cooled down and the working temperature of the rolling roller is maintained to extend the service life of the device. The temperature of the rolling roller is monitored by thermal expansion gas, and the position of the gate is adjusted to adjust the amount of water passing through the rolling roller, so that the temperature of the rolling roller is within an appropriate range.

[0046] When the molding sand is accumulated between the two rolling rollers, water pressure acts on the fourth sliding member, thereby pushing the sliding frame to move, separating the two rolling rollers, and causing the accumulated molding sand to fall, so as to maintain the normal temperature of the rolling rollers.

DETAILED DESCRIPTION

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The metal casting waste targeted by the present invention is molding sand.

[0056] A waste recycling device suitable for metal casting, such as Figure 1-Figure 5 As shown, it includes: a box body 1, the box body 1 is fixedly connected to a fixed frame 2, the box body 1 is slidably connected to a sliding frame 3, the sliding frame 3 and the fixed frame 2 are in contact with each other, the fixed frame 2 and the sliding frame 3 are both rotatably connected to a rolling roller 4, the box body 1 is fixedly connected to a power member 5, the output shaft of the power member 5 is transmitted to the fixed frame 2 and the sliding frame 3 through a sprocket chain, and the box body 1 is provided with a tensioner for adjusting the chain; a guide plate 6, rotatably connected to the box body 1, the guide plate 6 is located below the two rolling rollers 4; a sliding bar 301, slidably connected to the box body 1, and a first spring is provided between the sliding bar 301 and the sliding frame 3.

[0057] Further, such as Figure 1 , Figure 4 and Figure 5 As shown, it also includes: a first fixed shell 7 fixed to the box body 1; a first sliding member 8 slidably connected to the first fixed shell 7, and the first sliding member 8 is slidably connected to the guide plate 6.

[0058] Further, such as Figure 1 , Figure 3 and Figure 5 As shown, it also includes: a second fixed shell 9, fixedly connected to the box body 1, and the second fixed shell 9 is connected to the first fixed shell 7; a second sliding member 10, slidably connected to the second fixed shell 9, and the second sliding member 10 is fixed to the sliding frame 3; a sliding plate 11, slidably connected in the second fixed shell 9, and a second spring and a thin rope are arranged between the sliding plate 11 and the second sliding member 10.

[0059] In the above scheme, the aim is to reduce the wear of the rolling roller 4 by metal impurities. The box body 1 is provided with an inlet 101, a first outlet 102 and a second outlet 103. The inlet 101 is used to put the sand mold that needs to be crushed, the first outlet 102 is used to discharge the crushed sand, and the second outlet 103 is used to discharge large pieces of metal impurities and uncrushed sand. The two rolling rollers 4 rotate in opposite directions (the rolling roller 4 on the left rotates clockwise, and the rolling roller 4 on the right rotates counterclockwise), so that the sand passes between the two rolling rollers 4. The power part 5 is a reduction motor. The guide plate 6 is used to change the position where the sand falls. The lower side of the guide plate 6 is initially located above the first outlet 102. The rotation axis of the guide plate 6 is located in the vertical plane where the symmetry axes of the two rolling rollers 4 are located. The first spring between the sliding bar 301 and the sliding frame 3 is initially in a compressed state, which is used to provide the two rolling rollers 4 with a spring. Sufficient pressure is applied to squeeze and crush the molding sand, and large pieces of metal impurities are passed through when the two rolling rollers 4 encounter them. Seals are provided between the first fixed shell 7 and the first sliding member 8 and between the second sliding member 10 and the second fixed shell 9. The first fixed shell 7 and the second fixed shell 9 are connected by a pipeline, and the two and the pipelines therebetween are filled with liquid for transmission. The second spring between the sliding plate 11 and the second sliding member 10 is used to provide a buffer distance for the second sliding member 10 to ensure that the two rolling rollers 4 can crush the molding sand normally. When encountering metal impurities, the second sliding member 10 produces a sufficiently large displacement and then drives the sliding plate 11 to move through the second spring, so that the sliding plate 11 drives the guide plate 6 to rotate, and the thin rope between the sliding plate 11 and the second sliding member 10 is used to enable the second sliding member 10 to pull the sliding plate 11 to reset.

[0060] Further, such as Figure 6 As shown, it also includes: a limiting column 12, which is slidably connected to the sliding plate 11, a third spring is arranged between the limiting column 12 and the sliding plate 11, and the second fixed shell 9 is provided with a groove for the limiting column 12 to be inserted.

[0061] In the above scheme, the sliding plate 11 is limited to prevent the second sliding member 10 from driving the sliding plate 11 to vibrate when the second sliding member 10 vibrates with a small amplitude. The limiting column 12 is composed of a cylinder and a hemisphere, the groove on the second fixed shell 9 fits with the hemisphere of the limiting column 12, and the depth of the groove on the second fixed shell 9 is less than the radius of the hemisphere of the limiting column 12. When the second spring between the sliding plate 11 and the second sliding member 10 is compressed to the limit position, the elastic force generated is greater than the maximum resistance of the limiting column 12 to the sliding plate 11, so that when the second spring is compressed to the limit, the sliding plate 11 moves.

[0062] Further, such as Figure 1 and Figure 3 As shown, it also includes: a threaded rod 13, which is threadedly connected to the box body 1, and the threaded rod 13 is rotatably connected to the sliding bar 301.

[0063] In the above scheme, the elastic force of the first spring between the sliding bar 301 and the sliding frame 3 is adjusted. When adjusting the elastic force of the first spring between the sliding bar 301 and the sliding frame 3, the elastic force of the first spring is greater than the force required to crush the molding sand, so as to reduce the pressure on the two rolling rollers 4 when rolling the metal block, thereby reducing the damage to the rolling rollers 4.

[0064] Working process: When using the device, first place the device at the working place, then rotate the threaded rod 13, so that the threaded rod 13 drives the sliding bar 301 to move, adjust the distance between the sliding bar 301 and the sliding frame 3, thereby changing the initial elastic force of the first spring between the two, and then turn on the power to start the power piece 5, the power piece 5 drives the two rolling rollers 4 to rotate through the sprocket chain, and then fills the initially crushed molding sand into the feeding port 101, the molding sand is further crushed by the two rolling rollers 4, and then falls onto the guide plate 6, moves along the guide plate 6 and is discharged through the first discharging port 102, when large pieces of metal are mixed in the molding sand, the two rolling rollers 4 squeeze the metal and move downward, because the metal cannot be crushed, the rolling roller 4 on the right is squeezed to the right, the rolling roller 4 drives the sliding frame 3 to move to the right and compresses the adjacent first spring, the sliding frame 3 drives the second sliding piece 10 to move, the second sliding piece 10 compresses the adjacent second spring, and the thin rope relaxes at the same time.

[0065] When the elastic force of the second spring is sufficient to push the sliding plate 11 to move, the second spring pushes the sliding plate 11 to move, and the sliding plate 11 drives the limiting column 12 to move. The limiting column 12 is squeezed by the second fixed shell 9 and moves upward and compresses the adjacent third spring. When the limiting column 12 is separated from the groove of the second fixed shell 9, the sliding plate 11 moves to the right under the action of the third spring and tightens the thin rope again. When the sliding plate 11 moves, the liquid in the second fixed shell 9 is pressed into the first fixed shell 7 through the pipeline. The increase in liquid in the first fixed shell 7 pushes the first sliding member 8 to move to the left. The first sliding member 8 pushes the guide plate 6 to rotate, and the first sliding member 8 slides relative to the guide plate 6, thereby The metal is made to fall into the second discharge port 103 along the guide plate 6, thereby separating the large pieces of metal from the molding sand. After the metal passes through the two rolling rollers 4, the sliding frame 3 is reset under the action of the first spring, and at the same time, the sliding frame 3 drives the second sliding member 10 to reset. The second sliding member 10 pulls the sliding plate 11 to reset by a thin rope. After the sliding plate 11 is reset, the limiting column 12 is inserted into the groove of the second fixed shell 9 under the action of the third spring. When the sliding plate 11 is reset, the first sliding member 8 is reset by hydraulic transmission, and the first sliding member 8 drives the guide plate 6 to reset, thereby continuing to crush the molding sand. When the work is completed, turn off the power supply and the power part 5 stops rotating.

[0066] Further, such as Figure 1 and Figure 5 As shown, it also includes: a mounting frame 14, which is fixed to the box body 1, and the rolling roller 4 is provided with a cavity; there are two water-through shells 15, both of which are slidably connected to the mounting frame 14, and the two water-through shells 15 are respectively rotatably connected and communicated with the adjacent rolling rollers 4, and the two water-through shells 15 and the two rolling rollers 4 are all connected with the circulating cooling device; there are two gates 16, which are respectively slidably connected to the adjacent water-through shells 15, and the gates 16 are used to adjust the flow area of ​​the water-through shells 15.

[0067] Further, such as Figure 4 and Figure 5 As shown, it also includes: two sliding rods 17, which are slidably connected to adjacent water-passing shells 15 respectively, and the sliding rods 17 are fixedly connected to the adjacent gates 16; a third fixed shell 18, which is fixedly connected to the mounting frame 14; a third sliding member 19, which is slidably connected to the third fixed shell 18, and the third sliding member 19 is fixedly connected to the connecting rod 20, and the two sliding rods 17 are both slidably connected to the connecting rod 20.

[0068] Further, such as Figure 4 , Figure 5 and Figure 7As shown, it also includes: two air storage shells 21, which are respectively fixed to adjacent rolling rollers 4, and the air storage shells 21 are filled with thermal expansion gas; two connecting shells 22, which are both slidably connected to the mounting frame 14, the connecting shells 22 are connected to the third fixed shell 18, and the air storage shells 21 are connected to the adjacent connecting shells 22.

[0069] In the above scheme, the temperature of the rolling roller 4 is controlled to avoid the rolling roller 4 being overheated and thus shortening its service life. The water-passing shell 15 and the gate 16 cooperate to adjust the cross-sectional area of ​​the water flow, thereby adjusting the amount of water entering the cavity of the rolling roller 4 per unit time. The circulating cooling device is an existing device for supplying water and dissipating the heat of the refluxed water, which will not be described in detail here. A seal is provided between the third fixed shell 18 and the third sliding member 19. The third fixed shell 18 and the two connecting shells 22 and the gas storage shell 21 and the connecting shell 22 are all connected through pipes. The pipes adjacent to the gas storage shell 21 pass through the adjacent rolling roller 4. The thermal expansion gas in the gas storage shell 21 is used to monitor the temperature of the rolling roller 4. The adjacent part of the rolling roller 4 and the adjacent connecting shell 22, the gas storage shell 21 and the pipes adjacent to it are all made of thermal insulation materials to reduce the influence of cooling water on the thermal expansion gas in the gas storage shell 21 and improve the accuracy of the thermal expansion gas monitoring the temperature of the rolling roller 4.

[0070] Further, such as Figure 5 As shown, it also includes: a fourth fixed shell 23, fixedly connected to the box body 1, wherein one water-permeable shell 15 is provided with a water inlet 1501 and a drain outlet 1502, and the fourth fixed shell 23 is connected to the water inlet 1501; a fourth sliding member 24, slidably connected to the fourth fixed shell 23, and the fourth sliding member 24 is fixedly connected to the sliding frame 3.

[0071] In the above scheme, the purpose is to clean the accumulated molding sand caused by the blockage of large pieces of molding sand, so as to maintain the stability of the temperature of the rolling roller 4. The gate 16 on the right is provided with a notch to allow the water in the fourth fixed shell 23 to be discharged smoothly. When the upper side of the gate 16 is lower than the water inlet 1501, the cooling water will enter the fourth fixed shell 23 through the water inlet 1501, so that the water pressure acts on the fourth sliding member 24 and pushes the fourth sliding member 24 to move.

[0072] Working process: During the operation of this device, the friction between the rolling roller 4 and the molding sand generates heat, so the rolling roller 4 needs to be dissipated to avoid the rolling roller 4 from being too hot. At this time, the circulating cooling device is started to pass water into the water-passing shell 15, and then the water enters the rolling roller 4, thereby taking away the heat of the rolling roller 4, and then returns to the circulating cooling device from the rolling roller 4 to cool the cooling water, and then it is recycled. When the temperature of the rolling roller 4 fluctuates, taking the temperature rise as an example, the temperature of the thermal expansion gas in the air storage shell 21 rises and expands, and the air pressure in the connecting shell 22 connected to it rises together, and the air pressure in the third fixed shell 18 rises, pushing the third sliding member 19 to move downward, the third sliding member 19 drives the connecting rod 20 to move downward, the connecting rod 20 drives the sliding rod 17 to move, and the sliding rod 17 drives the gate 16 to move, thereby increasing the flow area of ​​the water-passing shell 15, and then increasing the water volume, thereby improving the cooling effect on the rolling roller 4.

[0073] When the molding sand between the two rolling rollers 4 is blocked and cannot be discharged smoothly, the two rolling rollers 4 continue to rub against the molding sand. When the gate 16 is opened to the maximum, the temperature of the rolling roller 4 cannot be stabilized. At this time, the third sliding member 19 continues to move downward and drives the gate 16 to move downward until the upper side of the gate 16 is lower than the water inlet 1501. At this time, cooling water enters the pipeline through the water inlet 1501, and then enters the fourth fixed shell 23. The pressure in the fourth fixed shell 23 increases, pushing the fourth sliding member 24 to move, and the fourth sliding member 24 drives the sliding frame 3 to move, and the sliding frame 3 drives the adjacent rolling roller 4 to move. When the sliding frame 3 moves, the transmission guide plate 6 rotates, and the distance between the two rolling rollers 4 increases, so that the blocked molding sand is discharged to the second discharge port 103 through the guidance of the guide plate 6, thereby separating the unbroken molding sand from the broken molding sand.

[0074] After the accumulated molding sand is discharged, the temperature of the rolling roller 4 gradually returns to normal, the temperature of the thermally expanded gas in the air storage shell 21 decreases, and the third sliding member 19 is driven to reset. The third sliding member 19 drives the gate 16 to move upward through the connecting rod 20 and the sliding rod 17. When the upper side of the gate 16 is higher than the water inlet 1501, the water in the fourth fixed shell 23 loses the water pressure supply. At this time, the sliding frame 3 is reset under the action of the adjacent first spring, and pushes the fourth sliding member 24 to reset. The fourth sliding member 24 presses the water in the fourth fixed shell 23 into the water inlet 1501 through the pipe, and then enters the water-passing shell 15, and then is discharged from the drain port 1502.

[0075] Please refer to Figure 1-Figure 7 A method for recycling waste suitable for metal casting, based on the above-mentioned waste recycling device suitable for metal casting, specifically comprises the following steps:

[0076] S1: When using the device, first place the device at a work location, rotate the threaded rod 13, adjust the distance between the sliding bar 301 and the sliding frame 3, and thus change the initial elastic force of the second spring between the two;

[0077] S2: Turn on the power supply to start the power member 5, which drives the two rolling rollers 4 to rotate. The waste is crushed by the two rolling rollers 4, and then falls onto the guide plate 6, slides along the guide plate 6 into the first discharge port 102 and is discharged;

[0078] S3: When the power part 5 is started, the circulating cooling device is started, and the cooling water enters the rolling roller 4, thereby taking away the heat of the rolling roller 4, and then returns to the circulating cooling device from the rolling roller 4 to cool the cooling water;

[0080] S5: After the metal passes through the two crushing rollers 4, the sliding frame 3 is reset under the action of the first spring, and at the same time, the sliding frame 3 drives the sliding plate 11 to reset, and the sliding plate 11 drives the guide plate 6 to reset, so as to continue to crush the waste;

[0081] S6: When the temperature of the rolling roller 4 changes, the volume of the thermally expanded gas in the gas storage shell 21 changes, so that the transmission gate 16 moves, so that the temperature of the rolling roller 4 is controlled within the normal working range;

[0082] S7: When the waste between the two rolling rollers 4 is blocked and cannot be discharged smoothly, the gate 16 moves downward until the upper side of the gate 16 is lower than the water inlet 1501, so that the water pressure acts on the fourth sliding member 24, so that the fourth sliding member 24 drives the two rolling rollers 4 to separate, and then the accumulated waste is discharged, and the sliding frame 3 drives the guide plate 6 to rotate, and then the sliding frame 3 is reset under the action of the first spring, and the guide plate 6 and the fourth sliding member 24 are driven to reset;
