Description

Technical Field

[0001] This application relates to the field of regeneration technology, and more specifically, to a quick disc changing device for a convenient centrifugal disc regeneration machine. Background Technology

[0002] In the field of mechanical casting, molding sand casting is the main process for casting production. After the casting is formed, the molding sand model can mostly not be directly reused, nor can it be simply broken down and remade. According to statistics, for every ton of castings produced, an almost equal amount of used sand is generated simultaneously. If large amounts of used sand are directly discarded, it not only occupies land resources but also causes environmental problems such as soil pollution and dust pollution; at the same time, casting companies continuously purchase new sand, resulting in high costs for new sand purchases and transportation. Recycling and reusing used sand can effectively solve the above-mentioned environmental problems, significantly reduce production costs, and generate huge economic and social benefits. Therefore, centrifugal regenerators are common equipment for the mechanical regeneration of used sand.

[0003] A high-efficiency four-step centrifugal regeneration machine with publication number CN213729174U is described. This patent can control the rotation direction of the drive motor to make the centrifugal discs rotate in different directions, and can also control the rotation direction of the drive motor to make the centrifugal discs rotate in the same direction, making it more flexible to use.

[0004] Although the aforementioned patent allows for different rotation directions of the centrifugal disc, the centrifugal disc cannot be replaced after long-term use, resulting in a decrease in the surface flatness of the centrifugal disc. This causes the movement trajectory of the sand particles under centrifugal force to become disordered, leading to uneven collisions and friction between sand particles and between sand particles and the centrifugal disc during old sand regeneration, thus reducing the old sand decoction effect.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figures 1-6 A quick disc changing device for a convenient centrifugal grinding disc regeneration machine includes a body 1, a motor 3 on the top of the body 1, a rotating shaft 12 fixedly connected to the output end of the motor 3, the rotating shaft 12 being rotatably connected to the body 1, a plurality of centrifugal discs 11 on the outer wall of the rotating shaft 12, and mounting components between the plurality of centrifugal discs 11 and the rotating shaft 12.

[0030] Each set of installation components includes a locking block 14, which is fixedly connected to the rotating shaft 12. The inner side of the centrifugal disc 11 is fixedly connected to a fixing ring 13. The outer wall of the locking block 14 is provided with multiple locking teeth. The inside of the fixing ring 13 is provided with multiple through slots. Each locking tooth matches the corresponding through slot. The bottom of the fixing ring 13 is provided with multiple auxiliary fixing components.

[0031] When the centrifuge disc 11 needs to be replaced after a period of use, first open the maintenance door 4. After opening, press the fixing section 15 of the bottom centrifuge disc 11. Because the middle of the fixing section 15 is hollow, pressing its two sides will cause the protrusion 16 to move inward. At this time, the fixing ring 13 can be separated from the card block 14, and then the centrifuge disc 11 can be removed.

[0032] During installation, first align the fixing section 15 with the groove 17. After alignment, insert the fixing section 15 into the groove 17. When inserting, because the protrusion 16 is an elastic structure, the protrusion 16 will be squeezed against the inner wall of the groove 17. When the protrusion 16 contacts the limiting grooves opened at both ends of the groove 17, it will spring back and be inserted into the limiting groove of the groove 17. At the same time, the locking teeth of the locking block 14 will also engage with the through groove of the fixing ring 13 to complete the installation.

[0033] The engagement of the locking block 14 with the locking tooth groove of the fixing ring 13, along with the auxiliary fixing structure of the L-shaped rod 20 and the fixing section 15, makes the installation and disassembly of the centrifugal disc 11 relatively simple, reducing the time and labor costs required to replace the centrifugal disc 11, improving the maintenance efficiency of the equipment, facilitating timely replacement of the centrifugal disc 11 after wear, and ensuring the regeneration effect of the equipment.

[0034] Reference Figures 3-5 Each set of auxiliary fixing components includes an L-shaped rod 20, each L-shaped rod 20 is fixedly connected to a fixing ring 13, the inside of the locking teeth of the locking block 14 is provided with a groove 17, one end of the L-shaped rod 20 is fixedly connected to a fixing section 15, and the outer wall of the fixing section 15 is fixedly connected to two protrusions 16, the fixing section 15 and the protrusions 16 are matched with the groove 17.

[0035] Reference Figures 3-6 Each centrifugal disc 11 is provided with a feeding frame 9 above it. A positioning ring 10 is fixedly connected to the top of each feeding frame 9. Multiple fixing frames 8 are fixedly connected to the inner wall of the machine body 1. Each fixing frame 8 has a placement groove inside it. The positioning ring 10 is inserted into the placement groove. The feeding frame 9 and the fixing frame 8 are connected by multiple fixing bolts 18. Each feeding frame 9 is located on the outer wall of the rotating shaft 12. Each feeding frame 9 has a rubber sleeve 19 on its inner side. Each rubber sleeve 19 is in contact with the rotating shaft 12.

[0036] When the bottom centrifugal disc 11 is removed, the fixing bolts 18 at the top of the fixing frame 8 are removed. Then the feeding frame 9 is tilted slightly. Because the feeding frame 9 has a rubber sleeve 19 inside, the feeding frame 9 can be tilted slightly when it is removed and moved. After tilting, the two feeding frames 9 at the top will not be obstructed by the fixing frame 8 when they are taken out.

[0037] During installation, first insert the positioning ring 10 into the placement groove, and then install the fixing bolts 18 to complete the installation of the material feeding frame 9.

[0038] Reference Figures 1-2 The machine body 1 has a feed inlet 2 at the top, a discharge bin 6 at the bottom, a maintenance door 4 at the front, a discharge port 7 at the bottom of the discharge bin 6, and a base 5 fixedly connected to the bottom of the machine body 1 by multiple rods.

[0039] After the old sand enters the portable centrifugal grinding disc regenerator through the feed inlet 2 at the top of the machine body 1, the motor 3 starts, and its output end drives the rotating shaft 12 to rotate, causing the multiple centrifugal discs 11 installed on the rotating shaft 12 to rotate at high speed, generating a strong centrifugal force, which throws the old sand from near the rotating shaft 12 to the edge of the centrifugal disc 11. During this process, the sand particles collide and rub against each other and against the surface of the centrifugal disc 11. Due to the flatness and special structure of the surface of the centrifugal disc 11, the sand particles fall from the edge and onto the feeding frame 9. The feeding frame 9 has a hollow structure, and the sand particles fall from the feeding frame 9 onto the second centrifugal disc 11. Driven by the centrifugal force generated by the high-speed rotation of the second centrifugal disc 11, the sand particles are thrown again and violently collide and rub against the disc and other sand particles, further removing residual impurities and achieving a deeper regeneration process. After repeated action by the multi-stage centrifugal discs 11, the demolding rate and cleanliness of the recycled sand are greatly improved. Finally, after being thrown out from the edge of the bottom centrifugal disc 11, it falls into the feeding hopper 6 at the bottom of the machine body 1 and is discharged through the feeding port 7 at the bottom of the feeding hopper 6, thus completing the entire old sand recycling process.

[0040] Working principle: The old sand enters from the top feed port 2 of the machine body 1. The motor 3 drives the rotating shaft 12 to rotate, which drives multiple centrifugal discs 11 to rotate at high speed. The centrifugal force causes the old sand to be thrown from near the rotating shaft 12 to the edge of the centrifugal discs 11. The collision and friction between sand particles and between sand particles and the disc body realize the initial demolding of the old sand. The thrown sand particles fall into the next centrifugal disc 11 through the hollow feeding frame 9. The process is repeated until the old sand is thrown out from the bottom centrifugal disc 11, falls into the feeding bin 6 and is discharged through the feeding port 7, thus completing the regeneration.

[0041] When the centrifuge disc 11 needs to be replaced, first open the maintenance door 4, press down on both sides of the fixing section 15, and use its internal hollow structure to drive the protrusion 16 to retract inward, so that the fixing ring 13 disengages from the locking block 14, thereby removing the centrifuge disc 11. During installation, align the fixing section 15 with the tank 17 and insert it. The elastic protrusion 16 is squeezed and contracted by the inner wall of the tank 17, and after reaching the limit groove, it springs back and locks in place. At the same time, the locking teeth of the locking block 14 engage with the through groove of the fixing ring 13, completing the installation.

[0042] The disassembly and assembly of the feeding frame 9 is coordinated with the replacement of the centrifugal disc 11. During disassembly, unscrew the top fixing bolts 18 of the fixing frame 8. Because the internal rubber sleeve 19 can deform and buffer, tilt the feeding frame 9 so that the top two feeding frames 9 avoid obstruction from the fixing frame 8 before removing it. During installation, insert the positioning ring 10 of the feeding frame 9 into the placement groove of the fixing frame 8, and then tighten the fixing bolts 18 to ensure the feeding frame 9 is stable, allowing the old sand to pass smoothly through the feeding frame 9 into the next-stage centrifugal disc 11 for processing.

[0043] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
