Abstract
Description
Technical Field
[0001] This utility model relates to the field of coated sand technology, and more specifically to a regenerable coated sand vibration device. Background Technology
[0002] Coated sand is a key material widely used in the foundry industry. Its surface is covered with a resin film to improve the strength and molding performance of the sand particles. During the casting process, after the coated sand is poured at high temperature, the resin film will solidify or carbonize, resulting in a large amount of resin film and impurities remaining on the surface of the sand particles. This affects the recycling of coated sand and consequently affects the surface quality and dimensional accuracy of the castings. Therefore, it is particularly important to deal with the impurities remaining on its surface in a timely manner. Existing recycled coated sand vibration devices mostly use eccentric wheels or mechanical knocking methods, with fixed vibration frequency and amplitude. This makes it difficult to adapt to coated sand with different particle sizes and adhesion strengths. Moreover, in the preheating process, a single heat source is often used, resulting in uneven heating of the material and some resin film not being fully softened, which affects the subsequent separation effect.
[0003] In view of the above-mentioned problems in the existing technology, this utility model provides a regenerable coated sand vibration device. By installing an annular heating pipe and an integrated leveling device in the heating box, the material can be uniformly heated and softened. Then, the electromagnetically driven vibration plate repeatedly bounces under the action of springs to achieve efficient vibration separation. Finally, the combination of a blower impurity collection component and an elastic unloading component further improves the efficiency and quality of coated sand regeneration, while also effectively reducing the energy consumption and operation difficulty of the device.

[0015] The technical effects and advantages of this utility model are as follows:
[0016] 1. This utility model uses a scraper to flatten the fed material, and then uses a heating tube to evenly heat the flattened material, which helps to soften the film on the material surface and improves the efficiency of subsequent separation. In addition, the design of a single discharge pipe and its placement in the middle of the bottom of the heating box avoids premature discharge of the material, prolongs the residence time of the material in the heating box, ensures that the film on the material surface can be fully softened, and reduces the difficulty of subsequent vibration processing.
[0017] 2. This utility model utilizes the combination of an electromagnetic plate, a metal strip, and a first spring to allow the metal strip to repeatedly bounce as it falls after being attracted by the electromagnetic plate, achieving high-frequency oscillation. This enables rapid material separation and enhances the separation effect. Furthermore, the first oscillating plate only consumes energy when energized and resets under gravity and the first spring after power is cut off, saving resources and operating costs. Combined with the repeated oscillation of the first and second oscillating plates, the material passes sequentially through the differently sized circular holes inside, ensuring uniform material distribution during oscillation and promoting efficient material separation.
[0018] 3. This utility model utilizes the negative pressure generated by the fan to separate the light impurities generated during the vibration process, and then collects the impurities to a designated location through a collection pipe, which facilitates subsequent processing and recycling, reduces environmental pollution and manual cleaning costs, and, with the addition of casters for free movement, effectively enhances the flexibility of this device in practical applications.
[0019] 4. Through the overall coordination of the unloading components, this utility model enables the material that has been vibrated to be discharged through the unloading hopper. Under the action of the second spring and the unloading baffle, spring-type automatic unloading is achieved, which improves the unloading speed. After unloading is completed, the automatic rebound of the second spring will directly pull the unloading baffle to close, which avoids material leakage and effectively reduces manual intervention.

In addition, the design of a single discharge pipe 108 and its placement at the bottom center of the heating box 104 avoids premature discharge of the material and prolongs the residence time of the material in the heating box 104, ensuring that the film on the surface of the material can be fully softened and reducing the difficulty of subsequent vibration processing.

The purpose is to achieve high-frequency oscillation by cooperating with the electromagnetic plate 302, the metal strip 304 and the first spring 307, so that the metal strip 304 can repeatedly jump when it falls after being attracted by the electromagnetic plate 302, so that the material can be separated quickly and the separation effect is enhanced. The first vibrating plate 303 only consumes energy when it is powered on, and resets by gravity and the first spring 307 after the power is cut off, saving resources and operating costs. Combined with the repeated oscillation of the first vibrating plate 303 and the second vibrating plate 308, the material passes through the round holes of different sizes inside in sequence, so that the material is evenly distributed during the oscillation process, and the material can be separated efficiently.
[0034] Reference Figure 1 and Figure 6The unloading assembly 4 includes an unloading hopper 401, an unloading partition 402, a sliding plate 403, a sliding bar 404, a second spring 405, a limiting block 406, a fixing rod 407, and a handle 408.

A fixing rod 407 is also fixedly placed on the top of the unloading partition 402. A handle 408 is detachably installed on the side wall of the fixing rod 407 away from the unloading partition 402. The purpose is to allow the material that has been vibrated to be discharged through the unloading hopper 401 through the overall cooperation of the unloading assembly 4. Under the action of the second spring 405 and the unloading partition 402, spring-type automatic unloading is achieved, which improves the unloading speed. After unloading is completed, the automatic rebound of the second spring 405 will directly pull the unloading partition 402 to close, avoiding material leakage and effectively reducing manual intervention.
[0035] The working principle of this utility model is as follows: First, place the device in the working environment and move it to a suitable position using the casters 102 at the bottom of the control box 101. Then, connect the motor 201, heating power supply 205, electromagnetic plate 302, and other electrical equipment to complete the preparation work. When vibration is required, put the material to be processed into the heating box 104 through the feed inlet 105 and start the motor 201. The motor 201 will drive the transmission rod 202, which is movably connected to it, to rotate through the coupling. Since the transmission rod 202 passes through the opening in the middle of the top of the heating box 104 and is movably inserted into the rotating shaft 203, it will indirectly drive the rotating shaft 203 to rotate together. At this time, under the rotation of the rotating shaft 203, the device is fixedly installed on the rotating shaft 302. The scraper 204 on the side wall of the rotating shaft 203 rotates along with the rotating shaft 203, thereby rotating and leveling the material fed into the feed inlet 105, so that the material can be evenly distributed at the bottom of the inner cavity of the heating box 104. At this time, the heating power supply 205 is turned on, and the heating tube 206 at the bottom of the heating power supply 205 will heat the inner cavity of the heating box 104. As the heating box 104 is heated, the impurities on the surface of the fed material will gradually soften. Since the bottom of the inner cavity of the heating box 104 is horizontal, the fed material will not move significantly in the heating box 104, thereby increasing the residence time of the fed material in the heating box 104 and ensuring that it is fully softened. With the continuous feeding of material into the feed inlet 105 and the continuous scraping of the scraper 204, the material is further softened. The material at the bottom of the inner cavity of the heating box 104 accumulates, gradually moving from the periphery towards the center of the bottom of the inner cavity. It then falls through the discharge pipe 108 in the center of the bottom of the inner cavity into the operating box 101, accumulating on the surface of the first vibrating plate 303. At this time, the electromagnetic plate 302 is energized, and it uses magnetic force to attract the metal strip 304 upwards. Since the metal strip 304 is fixedly installed on both sides of the first vibrating plate 303, it indirectly pulls the first vibrating plate 303 closer to the electromagnetic plate 302. When the preset height is reached, the power is de-energized, and the first vibrating plate 303 falls downwards under the influence of gravity, contacting the first spring 307 at the bottom. Under the action of the first spring 307, it repeatedly bounces. This operation is repeated to achieve high efficiency. During the vibration process, the material falls through the round holes inside the first vibration plate 303 into the second vibration plate 308 for further vibration. Finally, it falls through the round holes inside the second vibration plate 308 onto the surface of the collecting plate 309. Simultaneously, the blower 106 is activated, generating negative pressure to extract the lightweight impurities that have been separated during vibration. These impurities are then collected through the collection pipe 107 on the side of the blower 106 away from the control box 101, preventing contamination. When the vibrated material falls onto the surface of the collecting plate 309, because the collecting plate 309 is tilted (the side closer to the blower 106 is higher, and the side farther from the blower 106 is lower), the material will move towards the side farther from the blower 106 under the influence of gravity.Guided by the guide bar 310, the material is directed to the discharge chute on the side wall of the control box 101. When the vibrated material needs to be removed, an external force is applied to the handle 408 and pulled upwards. This causes the handle 408 to pull the discharge baffle 402 upwards via the fixing rod 407. At this time, the second spring 405 is in a contracted state, allowing the material to flow out of the discharge hopper 401 for collection. When collection is complete or paused, the force applied to the handle 408 is released. The second spring 405 then rebounds and extends, causing the discharge baffle 402 to return to its original position, blocking the discharge hopper 401 and stopping the discharge.
