Description

Technical Field

[0001] This invention relates to a steel shot recovery device, and more particularly to a steel shot separation and cooling device. Background Technology

[0002] In the overall sand casting process, steel shot plays a crucial role. It can not only serve as a cooling medium for molding sand molds, but also be reused. After the temperature of the steel shot is lowered by natural air cooling or spraying, it can be dropped into the steel shot box again. However, since some molding sand particles formed by the solidification of molten steel will adhere to the steel shot after the sand casting process, it needs to be further screened before the steel shot can be recycled.

[0003] Traditionally, steel shot and molten steel slag separation is achieved through direct filtration using a filter screen. However, since both the steel shot and molding sand slag are still warm at this stage, they adhere to each other, making filtration difficult and resulting in a large amount of molding sand particles remaining unfiltered. Therefore, existing methods employ vibration separation. While this can lower the temperature of the steel shot and disperse the molding sand slag, the particle size of the molding sand slag and the slag adhering to the steel shot is difficult to control. Even after vibration separation, many small particles remain mixed in with the steel shot, requiring multiple stages of vibration separation. This process is challenging, and excessively vigorous staged vibration can also prevent the steel shot from cooling down, resulting in poor separation and cooling effects.

[0004] Therefore, this invention aims to provide a steel shot separation and cooling device that can not only separate steel shot from molding sand, but also remove molding sand residue adhering to the steel shot. At the same time, it can also cool the steel shot directly on the recycling path, thereby increasing the molding sand recovery rate. In addition, the temperature of the recycled steel shot is suitable and can be put into use quickly. Summary of the Invention

[0005] This invention provides a steel shot separation and cooling device, which can effectively solve the above-mentioned problems.

[0006] This invention is implemented as follows:

[0007] A steel shot separation and cooling device includes: an outer separation box, which comprises, from bottom to top, a lower transfer layer, a separation layer, and a feeding layer. A speed reducer is connected to the lower transfer layer, and the speed reducer is connected via a belt to a sand screening cylinder located in the separation layer. The sand screening cylinder has several sieve holes that allow only molding sand to pass through. The other end of the sand screening cylinder is connected to a bearing seat. A steel shot mixture is fed through the feeding layer into the rotating sand screening cylinder, allowing the molding sand to enter the sand screening cylinder and blocking the steel shot from the outside. The top of the feeding layer is also connected to a feed pipe and an external air inlet pipe. The device further includes:

[0008] The material distribution and guiding structure includes two guide inclined baffles in the material feeding layer, and two surrounding plates connected between the two inclined baffles. The inclined baffles and surrounding plates form a funnel-shaped material feeding structure. The material distribution and guiding structure includes a crushing and separating component installed at the upper end of the sand screening cylinder. The crushing and separating component rotates in the opposite direction to the sand screening cylinder. A guide component is installed on the inclined baffle. The guide component and the crushing and separating component are spaced apart, and the gap between the guide component and the crushing and separating component is smaller than the diameter of the steel shot.

[0009] The sand-splitting structure has a pressure plate connected between the two enclosure plates. The inclined baffle is provided with an upper adjusting member and a lower adjusting member facing the pressure plate. The upper adjusting member is located at the upper end of the guide assembly and pushes the steel shot on the guide assembly toward the pressure plate. The lower adjusting member is located inside the guide assembly and pushes the steel shot on the guide assembly toward the crushing and separating assembly.

[0010] As a further improvement, the sand screening cylinder includes a cage body welded from reinforcing bars, with a plurality of screening plates embedded between the cage bodies, the aperture of the screening plates being smaller than that of steel shot.

[0011] As a further improvement, the crushing and separating assembly includes a drive frame connected to the rotating rod of the sand screening cylinder, the drive frame being connected to a roller press cylinder, and the roller press cylinder having several hammer points locked on it.

[0012] As a further improvement, the bottom of the pressure plate is provided with several clearance grooves, which are adapted to the hammer impact point, and the bottom of the pressure plate is attached to the upper tangent surface of the roller cylinder.

[0013] As a further improvement, the guide assembly includes a first guide rail and a second guide rail connected to the inclined baffle, the second guide rail being located at the lower end of the first guide rail, the upper adjusting member being disposed above the first guide rail, the lower adjusting member being disposed between the first guide rail and the second guide rail, and the distance between the first guide rail and the compaction separation assembly being greater than the distance between the second guide rail and the compaction separation assembly.

[0014] As a further improvement, both the first guide rail and the second guide rail are inclined from the middle position to both sides, and both the first guide rail and the second guide rail are inclined towards the crushing and separating component.

[0015] As a further improvement, the upward adjusting component includes a first high-speed motor disposed inside the inclined baffle, and an upper extrusion head is connected to the output end of the first high-speed motor. The end of the upper extrusion head is provided with several mating protrusions.

[0016] As a further improvement, the downward adjusting component includes a second high-speed motor disposed inside the inclined baffle, and a lower extrusion head is connected to the output end of the second high-speed motor. The lower end of the lower extrusion head and the side near the crushing and separating component are both elastic extrusion surfaces.

[0017] As a further improvement, two partition plates are connected between the outer sides of the inclined baffle. The partition plates, the inclined baffle, and the inner wall of the outer separation box form a drying zone. The ends of the first guide rail and the second guide rail extend into the drying zone. The outer air intake pipe connects to the two air intake manifolds and extends into the two drying zones. A material receiving trough is provided at the lower end of the drying zone.

[0018] As a further improvement, a sand storage hopper is provided on the outer side of the sand screening cylinder, and a discharge valve is provided at the bottom of the sand storage hopper.

[0019] The beneficial effects of this invention are:

[0020] Existing technologies suffer from difficulties in controlling the particle size of molding sand residue and slag adhering to steel shot. Even after vibration separation, a significant number of small particles remain mixed in the steel shot, requiring multiple stages of vibration separation, which is challenging and increases the temperature of the steel shot, resulting in poor cooling. Therefore, this invention utilizes a material distribution and guiding structure. First, the mixture of molding sand and steel shot is fed into the feed pipe, falling into the gap between the crushing and separating component and the guiding component. During this process, both the crushing and separating component and the sand screening cylinder rotate continuously. The molding sand passes through the screen holes on the surface of the sand screening cylinder, while the crushing and separating component continuously disperses the material, separating the molding sand from the steel shot. The molding sand flows away from the bottom, while the steel shot is guided by the guiding component to roll away from both sides, achieving two-way separation. Furthermore, because the steel shot follows a separate path during separation, it also cools down during the flow, resulting in clean, cooled steel shot that can be directly used.

[0021] The sand screening cylinder serves as a transition channel for molding sand. However, different molding sands have different particle sizes. In order to ensure that the molding sand can pass through each time and to adapt to molding sand molds with more formulations, this invention sets the screening plate and the cage to be movable. This allows different screening plates to be replaced according to the specific size of the molding sand, so as to better separate steel shot from molding sand.

[0022] The steel shot mixture poured from the top is actually partly in clumps. If this part is placed directly on the sand screening cylinder, it will be difficult to break it up. Therefore, the present invention sets a crushing and separating component at the top of the sand screening cylinder. The roller cylinder is driven to rotate by the drive frame connected to the sand screening cylinder, so that the roller cylinder can squeeze the clumps of mixture onto the inclined baffle and crush them, thereby achieving the purpose of rapid material separation.

[0023] After separation, the molding sand falls into the screening cylinder, while the steel shot remains at the top of the screening cylinder. If this portion is not removed, it will remain at the top of the screening cylinder, thus blocking the channel that originally allowed the molding sand to pass through. Therefore, this invention uses a guide component, through a first guide rail and a second guide rail, to guide the steel shot to both sides. The distance between the first guide rail and the second guide rail is different, thus providing two layers of protection. At the same time, the first guide rail and the second guide rail have a certain slope in both directions, which can guide the steel shot to both sides while preventing the molding sand from accumulating at the top of the guide rail.

[0024] When steel shot cools the molding sand mold, some molding sand adheres to the steel shot, causing the steel shot to increase in volume. This portion of steel shot also rolls with the guide assembly, and it is impossible to identify whether it is relatively clean steel shot, resulting in molding sand being mixed into the steel shot. Therefore, this invention sets up an adjusting sand separating structure on the basis of the material distribution and guiding structure. It can use the upper and lower adjusting components to vibrate the steel shot at high frequency, pressing the steel shot towards one side of the crushing and separating assembly, grinding the molding sand residue adhering to the surface of the steel shot into molding sand, which falls down along the gap between the guide assembly and the crushing and separating assembly, thereby obtaining relatively pure steel shot that can be used directly.

[0025] During the vibration process of the upward and downward adjusting components, instead of shaking the material, a high-frequency vibration method similar to that of a fascia gun is used. A high-speed motor drives the extrusion head to move, causing the steel shot to come into contact with the crushing and separating components or the sand screening cylinder through high-frequency vibration. This removes all the molding sand residue adhering to the surface of the steel shot, resulting in steel shot with a clean surface tempering. No further operation is required in subsequent uses.

[0026] The separated steel shot still has a certain temperature at this time. If it is used directly, the temperature will obviously not meet the standard. Therefore, the present invention sets a partition plate on the outside of the inclined baffle to divide it into two areas. A cooler airflow is continuously introduced into the drying area, so that the rolling steel shot and the steel shot falling into the receiving trough can be continuously subjected to the effect of the cold air, so that the temperature of the steel shot can meet the requirements.

Detailed Implementation

[0036] All embodiments of the present invention are intended to fall within the scope of protection of the present invention.

The technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of those features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] Reference Figures 1-6 As shown, a steel shot separation and cooling device includes: an outer separation box 10, which comprises, from bottom to top, a lower transfer layer 11, a separation layer 12, and a feeding layer 13. A reducer 20 is connected to the lower transfer layer 11, and the reducer 20 is connected to a sand screening cylinder 30 located in the separation layer 12 via a belt. The sand screening cylinder 30 has several screen holes 31 that allow only molding sand to pass through. The other end of the sand screening cylinder 30 is connected to a bearing seat. A steel shot mixture is fed into the rotating sand screening cylinder 30 through the feeding layer 13, allowing the molding sand to enter the sand screening cylinder 30 and blocking the steel shot from the outside. The top of the feeding layer 13 is also connected to a feed pipe and an external air inlet pipe 40. The device also includes: a material distribution and guiding structure 50, in which two guide inclined baffles 131 are provided in the feeding layer 13, and two surrounding plates 132 are connected between the two inclined baffles 131. The inclined baffles 131 and the surrounding plates 132 form a... A funnel-shaped feeding structure is provided. The material distribution and guiding structure 50 includes a crushing and separating component 51 disposed at the upper end of the sand screening cylinder 30. The crushing and separating component 51 rotates in the opposite direction to the sand screening cylinder 30. A guiding component 52 is disposed on the inclined baffle 131. The guiding component 52 and the crushing and separating component 51 are spaced apart, and the gap between the guiding component 52 and the crushing and separating component 51 is smaller than the diameter of the steel shot. A directional sand distribution structure 60 is provided. A pressure plate 133 is connected between the two surrounding plates 132. An upper directional component 61 and a lower directional component 62 are disposed on the inclined baffle 131 facing the pressure plate 133. The upper directional component 61 is located at the upper end of the guiding component 52. The upper directional component 61 pushes the steel shot on the guiding component 52 toward the pressure plate 133. The lower directional component 62 is located inside the guiding component 52. The lower directional component 62 pushes the steel shot on the guiding component 52 toward the crushing and separating component 51.

[0039] Existing technologies suffer from difficulties in controlling the particle size of molding sand residue and slag adhering to steel shot. Even after vibration separation, a significant number of small particles remain mixed in the steel shot, requiring multiple stages of vibration separation, which is challenging. Furthermore, the multiple vibration stages increase the temperature of the steel shot, resulting in poor cooling during separation. Therefore, this embodiment utilizes a material distribution and guiding structure 50. First, the steel shot mixture containing molding sand is fed into the feed pipe, causing it to fall into the gap between the compaction and separation component 51 and the guiding component 52. During this process, the compaction and separation component... Both component 51 and the sand screening cylinder 30 rotate continuously. Molding sand can enter the interior of the sand screening cylinder 30 through the screen holes 31 on the surface of the sand screening cylinder 30. The crushing and separating component 51 continuously disperses the material, separating the molding sand from the steel shot. The molding sand flows away from the bottom, while the steel shot is guided by the guiding component 52 and rolls away from both sides, achieving two-way separation. During the separation process, the steel shot travels a separate route, so it can also be cooled during the flow, thus obtaining clean, cooled steel shot that can be directly used.

[0040] The sand screening cylinder 30 serves as a transition channel for molding sand. However, different molding sands have different particle sizes. In order to ensure that the molding sand can pass through each time and to adapt to molding sand molds with more formulations, the sand screening cylinder 30 in this embodiment includes a cage body 33 welded from reinforcing ribs. Several screening plates 32 are embedded between the cage body 33. The aperture of the screening plates 32 is smaller than that of steel shot. The screening plates 32 and the cage body 33 are set to be movable, so that different screening plates 32 can be replaced according to the specific size of the molding sand to better separate steel shot from molding sand.

[0041] The steel shot mixture poured from the top is partially lumpy. If this portion is placed directly on the sieve cylinder 30, it will be difficult to break up. Therefore, in this embodiment, a crushing and separating assembly 51 is provided at the upper end of the sieve cylinder 30. The crushing and separating assembly 51 includes a drive frame 511 connected to the rotating rod of the sieve cylinder 30. The drive frame 511 is connected to a roller press 512, which has several hammer points 513 locked onto it. The drive frame 511, connected to the sieve cylinder 30, drives the roller press 512 to rotate, enabling the roller press 512 to break up the lumpy mixture. The material is squeezed onto the inclined baffle 131 and crushed, thereby achieving the purpose of rapid material separation. The hammer impact point 513 can form a certain point-to-point collision effect, improving the crushing ability. In order to block the steel shot and molding sand from passing through the top of the crushing and separating component 51, the bottom of the pressure plate 133 is provided with several clearance grooves 1331. The clearance grooves 1331 are adapted to the hammer impact point 513. The bottom of the pressure plate 133 is attached to the upper tangential surface of the roller cylinder 512, so that the pressure plate 133 can fit the shape of the roller cylinder 512 while achieving the sealing effect.

[0042] The separated molding sand falls into the screening cylinder 30, while the steel shot remains at the top of the screening cylinder 30. If this portion is not removed, it will remain at the upper end of the screening cylinder 30, thus blocking the channel originally for the molding sand to pass through. Therefore, the guiding component 52 in this embodiment includes a first guide rail 521 and a second guide rail 522 connected to the inclined baffle 131. The second guide rail 522 is located at the lower end of the first guide rail 521. The upper adjusting member 61 is disposed above the first guide rail 521, and the lower adjusting member 62 is disposed between the first guide rail 521 and the second guide rail 522. The distance between the first guide rail 521 and the compaction and separation component 51 is greater than the distance between the second guide rail 522 and the... The spacing between the compaction and separation components 51 is controlled by the guide components 52. The first guide rail 521 and the second guide rail 522 guide the steel shot to both sides. The spacing between the first guide rail 521 and the second guide rail 522 is different, thus providing two protective measures. At the same time, the first guide rail 521 and the second guide rail 522 have a certain slope in both directions. Specifically, the first guide rail 521 and the second guide rail 522 are both inclined from the middle to both sides. Moreover, the first guide rail 521 and the second guide rail 522 are both inclined towards the compaction and separation components 51, which can guide the steel shot to both sides while preventing the molding sand from piling up at the upper end of the guide rail.

[0043] When steel shot cools the molding sand mold, some molding sand adheres to the steel shot, causing the steel shot to increase in volume. This portion of steel shot also rolls with the guide component 52, and it is impossible to identify whether it is relatively clean steel shot, resulting in molding sand being mixed into the steel shot. Therefore, this invention sets up an adjusting sand separating structure 60 on the basis of the material distribution guide structure 50. It can use the upper adjusting component 61 and the lower adjusting component 62 to vibrate the steel shot at high frequency, pressing the steel shot towards one side of the crushing and separating component 51, grinding the molding sand residue adhering to the surface of the steel shot into molding sand, which falls down along the gap between the guide component 52 and the crushing and separating component 51, thereby obtaining relatively pure steel shot that can be used directly.

[0044] During the vibration process of the upward adjusting component 61 and the downward adjusting component 62, the method used is not shaking, but high-frequency vibration similar to that of a fascia gun. Specifically, the upward adjusting component 61 includes a first high-speed motor 611 disposed inside the inclined baffle 131. An upper extrusion head 612 is connected to the output end of the first high-speed motor 611. Several mating pins 613 are provided at the end of the upper extrusion head 612. The downward adjusting component 62 includes a second high-speed motor 621 disposed inside the inclined baffle 131. A lower extrusion head 622 is connected to the output end of the second high-speed motor 621. The lower end of the lower extrusion head 622 and the side near the crushing and separating component 51 are both elastic extrusion surfaces 623. The high-speed motor drives the extrusion head to move and vibrate at high frequency so that the steel shot comes into contact with the crushing and separating component 51 or the sand screening cylinder 30, thereby removing all the molding sand residue adhering to the surface of the steel shot, thus obtaining steel shot with a clean surface tempering. No further operation is required in subsequent use.

[0045] The separated steel shot still has a certain temperature at this time. If it is used directly, the temperature will obviously not meet the standard. Therefore, in this embodiment, two partition plates 134 are connected between the outer sides of the inclined baffle 131. The partition plates 134, the inclined baffle 131, and the inner wall of the outer separation box 10 form a drying zone. The ends of the first guide rail 521 and the second guide rail 522 extend into the drying zone. The outer air intake pipe 40 connects to the two air intake manifolds 41 and extends into the two drying zones. A receiving groove 42 is provided at the lower end of the drying zone. The partition plates 134 are provided on the outer side of the inclined baffle 131 to divide it into two areas. A cooler airflow is continuously introduced into the drying zone, so that the rolling steel shot and the steel shot falling into the receiving groove 42 can be continuously subjected to the effect of the cold air, so that the temperature of the steel shot can meet the requirements.

[0046] In order to better collect and recycle molding sand, a sand storage hopper 70 is provided on the outside of the sand screening cylinder 30. The bottom of the sand storage hopper 70 is equipped with a discharge valve, so that all the sand can be transferred and transported after a period of collection.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
