Description

Technical Field

[0001] This utility model relates to the field of cooling devices, and in particular to a casting sand cooling device. Background Technology

[0002] In the foundry industry, sand casting is a common method for producing castings. During the casting process, the transportation, storage, and heat dissipation of foundry sand play a crucial role in the quality of the castings and production efficiency. Foundry sand needs to maintain good sealing during feeding and storage to prevent dust leakage and impurities from entering. Simultaneously, efficient heat dissipation methods and measures to prevent sand agglomeration are required during heat dissipation to ensure its stable performance.

[0003] Currently, in foundry sand processing equipment, traditional hopper and tank connections are mostly fixed using bolts. This method is cumbersome, time-consuming to connect and disassemble, severely impacting production efficiency. Furthermore, it suffers from poor sealing, leading to leakage and affecting foundry sand quality and environmental cleanliness. Regarding heat dissipation and anti-caking, most equipment uses simple air cooling or water cooling, resulting in low and uneven heat dissipation efficiency, failing to quickly remove heat from the foundry sand. Simultaneously, the lack of effective vibration-based anti-caking devices allows the foundry sand to easily clump during storage, affecting subsequent use and leading to a decline in casting quality. Therefore, there is an urgent need to design a device that is easy to connect, reliably sealed, efficiently dissipates heat, and effectively prevents foundry sand from clumping.

[0004] In response to this technical problem, this application proposes a casting sand cooling device. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a casting sand cooling device. It achieves rapid docking between the hopper and the tank and sealing of the feed inlet through a limiting structure; it achieves uniform heat dissipation through water cooling circulation, large-scale tank swing and internal structure coordination; and it achieves anti-caking vibration through eccentric drive frequency adjustment, ensuring convenient device connection, uniform heat dissipation and good anti-caking effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A casting sand cooling device includes a tank body. A connecting block is fixedly connected to the inside of the top left side of the tank body. A positioning groove is opened on the top of the connecting block. A feed inlet is opened on the side of the connecting block. A baffle is provided inside the connecting block. A limit groove is opened on the side of the baffle. A pressing rod is provided at the bottom of the positioning groove. A compression rod is provided at the bottom of the pressing rod. A spring is provided at the bottom of the compression rod. A vibrating block is provided on the outer wall of the left end of the tank body. A top rod is fixedly connected to the bottom of the vibrating block. A sliding plate is fixedly connected to the bottom of the top rod. An eccentric column is provided on the lower side of the sliding plate. A rotating shaft is fixedly connected to both ends of the eccentric column. A spring is sleeved on the outer side of the top rod. A base is sleeved on the outer side of the sliding plate.

[0007] Furthermore, a limiting block is provided inside the limiting groove, and a feeding port is fixedly connected to the side of the limiting block.

[0008] Furthermore, a fixing block is provided on the top of the vibrating block, the bottom of the vibrating block is provided on the top of the base, and the bottom of the second spring is provided on the top of the sliding plate.

[0009] Furthermore, according to the casting sand cooling device according to claim 1, the inner wall of the tank is fixedly connected with a spiral cutter, the inner wall of the tank is fixedly connected with a stop block, and one side of the outer wall of the stop block is fixedly connected to the outer wall of one end of the spiral cutter.

[0010] Furthermore, a water-cooling pipe is fixedly connected to the outer wall of the tank, a second rotating shaft is fixedly connected to the left side of the tank, and a universal ball is fixedly connected to the right side of the tank.

[0012] Furthermore, a docking interface is provided on the bottom side of the discharge port for docking with the feed port for material discharge.

[0013] This utility model has the following beneficial effects: 1.

[0014] 2.

[0017] 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 a part of the present utility model. These are some examples, not all examples. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0018] Referring to Figures 1-3, one embodiment of this utility model provides a casting sand cooling device, including a tank 1. A connecting block 2 is fixedly connected to the top side of the left end of the tank 1. A positioning groove 3 is provided on the top of the connecting block 2. A feed inlet 4 is provided on the side of the connecting block 2. A baffle 5 is provided inside the connecting block 2. A limiting groove 6 is provided on the side of the baffle 5. A pressing rod 25 is provided at the bottom of the positioning groove 3. A compression rod 7 is provided at the bottom of the pressing rod 25. A spring 8 is provided at the bottom of the compression rod 7. A vibrating block 11 is provided on the outer wall of the left end of the tank 1. A top rod 16 is fixedly connected to the bottom of the vibrating block 11. A sliding plate 15 is fixedly connected to the bottom of the top rod 16. An eccentric column 14 is provided on the lower side of the sliding plate 15. A rotating shaft 13 is fixedly connected to both ends of the eccentric column 14. A spring 17 is sleeved on the outside of the top rod 16. A base 12 is sleeved on the outside of the sliding plate 15.

[0019] Specifically, this device uses a water-cooled pipe 23, which is wound and fixed to the outer wall of the tank 1, to cool the casting sand inside the tank 1. The water-cooled pipe 23 is fixedly connected to the tank 1, and the two ends of the water-cooled pipe 23 are made of flexible hoses with a certain amount of slack. The tank 1 uses a large-amplitude cyclical swing to make the casting sand inside the tank 1 roll and contact the inner wall of the tank 1, and conduct heat through the circulating water in the water-cooled pipe 23. During the feeding operation, first open the latch between the fixing block 21 and the vibrating block 11 to expose the connecting block 2 on the tank 1. Align the feeding port 9 of the hopper with the opening on the connecting block 2, and at the same time align the limiting block 10 with the positioning groove 3 and move it downwards. The limiting block 10 slides down along the limiting groove 6 to the bottom, which will press down the pressing rod 25. The pressing rod 25 then presses down the compression rod 7, compressing the spring 8, until the upper half of the compression rod 7 is completely detached from the bottom of the baffle 5 and enters the interior of the connecting block 2. At this point, the baffle 5 releases the rotation restriction imposed on the compression rod 7. Rotating the hopper causes the discharge port 9 to rotate, which in turn causes the limiting block 10 connected to the discharge port 9 to rotate. The limiting block 10 then causes the baffle 5 to rotate to the limiting position. At this point, the mating interface 22 on the discharge port 9 coincides with the inlet port 4 on the connecting block 2, completing the rapid connection between the hopper and the inside of the tank 1. The unloading operation of tank 1 is now performed. During the unloading process, the rotating shaft 13 is rotated so that the highest point of the eccentric column 14 acts on the sliding plate 15, slightly lifting the left side of tank 1 and causing the casting sand entering the tank 1 to slide to the right, ensuring smooth unloading. After unloading is completed, the hopper is rotated in the reverse direction so that the baffle 5 returns to its original position and blocks the feed inlet 4. When the rotation reaches the reverse limit, the limiting groove 6 aligns with the positioning groove 3, and the hopper is pulled upward. The limiting block 10 moves upward along the limiting groove 6 to the positioning groove 3 and disengages from the connecting block 2. At this time, the pressing rod 25 disengages from the limitation of the limiting block 10, and the spring 8 pushes up the compression rod 7 due to the elastic force, causing it to re-enter the baffle 5, completing the rotation limit of the baffle 5, and achieving the sealing of the feed inlet 4 of tank 1 and the sealing of tank 1.

[0020] Referring to Figures 1, 5, and 6, a limiting block 10 is provided inside the limiting groove 6, and a discharge port 9 is fixedly connected to the side of the limiting block 10. A fixing block 21 is provided on the top of the vibrating block 11, and the bottom of the vibrating block 11 is provided on the top of the base 12. The bottom of the second spring 17 is provided on the top of the sliding plate 15. A spiral blade 18 is fixedly connected to the inner wall of the tank body 1, and a stop block 19 is fixedly connected to the inner wall of the tank body 1. One side of the outer wall of the stop block 19 is fixedly connected to the outer wall of one end of the spiral blade 18. A water cooling pipe 23 is fixedly connected to the outer wall of the tank body 1, a rotating shaft 24 is fixedly connected to the left side of the tank body 1, and a universal ball 20 is fixedly connected to the right side of the tank body 1. The lower half of the outer wall of the pressing rod 25 is provided inside the baffle 5, the upper half of the outer wall of the compression rod 7 is provided inside the baffle 5, and the lower half of the outer wall of the compression rod 7 is provided inside the connecting block 2. The bottom side of the discharge port 9 has a docking interface 22 for docking with the feed port 4 for material discharge.

[0021] Specifically, the fixing block 21 is placed on top and locked to the vibrating block 11 using a latch, further securing the tank 1; the rotating shaft 13 is rotated to restore the tank 1 to a horizontal state. Water pumps are connected to both ends of the water-cooling pipe 23, which are connected to a circulating cooling water pool. Starting the water pumps connected to both ends of the water-cooling pipe 23 allows cooling water to flow into it. Since the water-cooling pipe 23 is wound and fixed to the outer wall of the tank 1, and the tank 1 uses a heat-conducting material, the flow of cooling water guides and dissipates the heat from the casting sand inside the tank 1. Simultaneously, the motor connected to the rotating shaft 24 on the left side of the tank 1 is started, causing the tank 1 to oscillate back and forth with a relatively large amplitude. The interior of the tank 1... The spiral cutter 18, through its back-and-forth oscillation, divides the casting sand into uniform small aggregates, achieving uniform heat dissipation. The baffle 19, through its oscillation, lifts the casting sand to a high point in the tank 1, allowing it to fall under gravity, thus fully dispersing the sand and bringing it into contact with the interior of the tank 1, ensuring that heat is fully conducted through the water-cooling pipe 23. After the casting sand in the tank 1 has cooled down, the motor connected to the rotating shaft 13 is started, and the rotating shaft 13 drives the eccentric column 14 to rotate. The eccentric movement of the eccentric column 14 drives the sliding plate 15 to move up and down, which in turn drives the vibrating block 11 to move up and down through the push rod 16, achieving the up-and-down vibration of the tank 1. The universal ball 20 on the right side of the tank 1 ensures that the right side of the tank 1 is fixed, and allows the left side of the tank 1 to move up and down slightly. The spring 17 between the base 12 and the sliding plate 15, through its elasticity, keeps the sliding plate 15 in contact with the eccentric column 14, ensuring that the movement trajectory of the eccentric column 14 is completely transmitted to the vibrating block 11. By adjusting the frequency of the motor connected to the rotating shaft 13, the frequency of the up-and-down movement of the vibrating block 11 can be controlled, achieving vibration of the tank 1 at different frequencies and preventing casting sand from clumping and adhering to the inner wall of the tank 1. After vibration is complete, the eccentric column 14 is rotated to its highest point, raising the left side of the tank 1 at a certain angle, opening the discharge port on the right side of the tank 1, and collecting the cooled and dried casting sand through the pre-reserved hole on the right side of the device. The spiral cutter 18 and the baffle 19 inside the tank 1 are both tilted to the left side of the tank 1, ensuring that the cooled casting sand is smoothly discharged from the discharge port.

[0022] Working principle: During material feeding, the locking mechanism between the fixing block 21 and the vibrating block 11 is opened, exposing the connecting block 2 on the tank body 1. The feeding port 9 of the hopper is aligned with the opening of the connecting block 2, and the limiting block 10 is aligned with the positioning groove 3 and moved downwards. The limiting block 10 slides down along the limiting groove 6 to the bottom, presses the pressing rod 25, and then pushes the compression rod 7 to compress the spring 8, causing the upper half of the compression rod 7 to disengage from the bottom of the baffle 5 and enter the connecting block 2, thus releasing the rotation restriction on the baffle 5. At this time, the hopper is rotated, causing the feeding port 9, the limiting block 10, and the baffle 5 to rotate. When it reaches the limiting position, the interface 22 of the feeding port 9 coincides with the feed port 4 of the connecting block 2, completing the quick connection between the hopper and the tank body 1, and realizing material feeding. During the feeding process, rotating shaft 13 causes the highest point of eccentric column 14 to act on sliding plate 15, slightly lifting the left side of tank 1 and causing the casting sand to slide to the right, ensuring smooth feeding. After feeding is completed, the hopper is rotated in the opposite direction, causing baffle 5 to reset and block inlet 4. When the device moves to the reverse limit, the limit groove 6 aligns with the positioning groove 3, the hopper is lifted, the limit block 10 disengages from the connecting block 2, the spring 8 lifts the compression rod 7, and the baffle 5 is restricted from rotating again, thus sealing the tank 1. Next, the fixing block 21 is placed on top and locked in place. The rotating shaft 13 is rotated to make the tank 1 horizontal, and the water pumps at both ends of the water cooling pipe 23 are started, circulating cold water to remove the heat from the casting sand. Simultaneously, the motor connected to the rotating shaft 24 on the left side of the tank 1 drives the tank 1 to swing. The internal spiral cutter 18 cuts the casting sand, and the baffle 19 lifts the casting sand to a high position on the tank 1, where it falls due to gravity, promoting full contact between the casting sand and the inner wall of the tank 1, and efficient heat dissipation through the water cooling pipe 23. After the casting sand has cooled, the rotating shaft 13 is started, and the eccentric column 14 drives the sliding plate 15, the push rod 16, and the vibrating block 11 to move up and down, causing the tank 1 to vibrate. The universal ball joint 20 on the right side of tank 1 ensures that the right side is fixed while the left side can move slightly. Spring 2 17 keeps the sliding plate 15 in contact with the eccentric column 14. The movement frequency of the vibrating block 11 is controlled by adjusting the motor frequency to ensure that there are no clumps of casting sand adhering to the inner wall of tank 1. After vibration, the eccentric column 14 is rotated to lift the left side of tank 1, opening the right-side discharge port and collecting the dried casting sand through the right-side opening of the device. Because the spiral cutter 18 and the baffle 19 inside tank 1 are tilted to the left, they will not obstruct the smooth discharge of cooled casting sand from the discharge port.
