Description

Technical Field

[0001] This utility model relates to the field of industrial production technology, and in particular to a sand recycling and reuse device for a sand cleaning machine. Background Technology

[0002] In industrial production processes, sand cleaning machines play an indispensable role as key equipment in casting cleaning and metal surface treatment. However, after completing their work, traditional sand cleaning machines often discard the discharged sand without fine processing, resulting in a significant waste of usable resources and placing a heavy burden on the environment.

[0003] In traditional sand cleaning operations without screening mechanisms, the sand mixture discharged from the sand cleaning machine is treated as waste. This mixture includes not only impurities but also a large amount of sand of acceptable size that is still usable. Due to the lack of effective screening methods, sand of different sizes is mixed with impurities, making it impossible to accurately separate the recyclable portion.

[0004] Meanwhile, the presence of ferromagnetic impurities such as iron filings and steel slag in the cleaned sand can cause numerous problems for its subsequent use. In the metal processing industry, these magnetic impurities, once mixed into the sand, can cause severe wear to critical components of the sand cleaning machine and related equipment, such as spray guns and conveying pipelines, during the sand recycling process, greatly shortening the equipment's service life and increasing maintenance and replacement costs.

[0005] Focusing on the air separation structure, without it, dust and light impurities mixed in the cleaned sand are difficult to remove. Dust not only disperses during sand transport and storage, polluting the working environment and endangering the health of operators, but it also easily accumulates inside the equipment, affecting its normal operation and increasing the risk of equipment failure.

[0006] Therefore, a sand cleaning machine sand recycling and reuse device is needed. Utility Model Content

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Example 1, as Figures 1 to 6 As shown, a sand cleaning machine sand recycling device includes a support frame 1. A feeding component 2 is fixedly connected to the upper front of the support frame 1. A screening mechanism 3 is fixedly connected to the upper side inside the support frame 1. A magnetic separation mechanism 5 is fixedly connected to the middle of the support frame 1. A sorting component 6 is fixedly connected to the lower rear side of the support frame 1. A transmission mechanism 4 is fixedly connected to the middle of the left end of the support frame 1.

[0028] The transmission mechanism 4 mentioned above consists of three pulleys, one belt, and one motor as in the prior art. Its specific installation method, circuit connection method, and control method are all conventional designs, and will not be described in detail in this utility model.

[0029] In the specific implementation process of this utility model, firstly, the internal drive structures of the feeding assembly 2, the transmission mechanism 4, and the sorting assembly 6 are activated to put the entire device into operation. Then, the worker feeds sand downwards from the internal structure of the feeding assembly 2. With the feeding assembly 2 in operation, the sand is fed evenly and stably into the internal structure of the screening mechanism 3. Then, the transmission mechanism 4 drives the internal structure of the screening mechanism 3 to vibrate, causing the sand to be screened. Sand with unqualified particle sizes is discharged from the rear of the screening mechanism 3, while qualified sand passes through the screening mechanism 3. Guided by the internal structure, the sand enters the internal structure of the magnetic separation mechanism 5. Then, through the action of the magnetic separation mechanism 5 itself and the transmission mechanism 4, the sand is conveyed backward. The magnetic material inside the sand during the conveying process is adsorbed by the internal structure of the magnetic separation mechanism 5. Then, under the action of the magnetic separation mechanism 5, the magnetic impurities are discharged outward from the front of the magnetic separation mechanism 5. The sand in the backward conveying process falls directly into the internal structure of the sorting component 6. Then, under the action of the internal structure of the sorting component 6, the sand after magnetic separation is air-separated, which can filter out the lighter impurities contained in the sand. The filtered sand is then collected inside the sorting component 6.

[0030] Example 2: In order to achieve uniform feeding, refer to... Figure 2 In this solution, the feeding assembly 2 includes a support tube 21, which is fixedly connected to the upper front of the support frame 1. A spiral blade 23 is rotatably connected to the upper wall of the inner cavity of the support tube 21. A motor 24 is fixedly connected to the middle of the upper end of the support tube 21. A feeding tube 22 is fixedly connected to the upper front side of the outer surface of the support tube 21.

[0031] Furthermore, the lower end of the support tube 21 passes through the upper end of the support frame 1 and extends to the outside, and the output end of the motor 24 passes through the upper end of the support tube 21 and is fixedly connected to the upper end of the spiral blade 23 through a coupling.

[0032] In the above process, sand is first fed into the inner cavity of the support pipe 21 from the feed pipe 22, and at the same time, the motor 24 is started, which drives the spiral blade 23 to rotate. While the spiral blade 23 is rotating, the sand inside the feed pipe 22 is evenly conveyed downward.

[0033] The specific installation method, circuit connection method, and control method of the motor-24 used above are all conventional designs, and will not be described in detail in this utility model.

[0034] Specifically, in order to achieve the purpose of screening sand, refer to Figure 3 In this scheme, the screening mechanism 3 includes several support blocks 31, a rotating rod 37, and a guide plate 35. The several support blocks 31 are rectangularly distributed and fixedly connected to the upper side of the inside of the support frame 1. The rotating rod 37 is rotatably connected to the upper side of the inner cavity of the support frame 1. The guide plate 35 is fixedly connected to the upper side of the middle part of the inner cavity of the support frame 1. The lower ends of the several support blocks 31 are all fixedly connected to springs 32. The lower ends of the several springs 32 are all fixedly connected to L-shaped plates 33. The lower ends of the several L-shaped plates 33 are all fixedly connected to a screen plate 34. The front side of the inside of the guide plate 35 is provided with a through hole 36. The left and right sides of the outer surface of the rotating rod 37 are fixedly connected to cams 38.

[0035] Furthermore, the sieve plate 34 is inclined, and the bottom wall of the guide plate 35 is inclined.

[0036] In the above process, the motor inside the transmission mechanism 4 drives the belt and pulley to rotate, which in turn drives the rotating rod 37 to rotate. As the rotating rod 37 rotates, it drives the cam 38 to rotate, which in turn strikes the bottom of the screen plate 34. Under the action of the spring 32, the screen plate 34 vibrates. When the sand falls onto the surface of the screen plate 34, the vibration of the screen plate 34 causes the qualified sand on its surface to fall into the guide plate 35. The sand that does not meet the particle size requirements slides outward through the inclined surface of the screen plate 34. The sand that enters the guide plate 35 then slides into the through hole 36 through its inclined surface.

[0037] Specifically, in order to filter out magnetic substances inside the sand, refer to Figure 4 In this scheme, the magnetic separation mechanism 5 includes a fixed plate 51, which is fixedly connected to the middle of the support frame 1. The upper front right and left sides of the fixed plate 51 are fixedly connected to the guard plates 52. The front and rear sides of the two guard plates 52 are rotatably connected to the opposite surfaces. The outer surfaces of the two guard plates 53 are wound together with a conveyor belt 54. The upper rear side of the fixed plate 51 has a hole 56. The middle and lower parts of the opposite surfaces of the two guard plates 52 are fixedly connected to the electromagnets 55. The two electromagnets 55 are located inside the conveyor belt 54.

[0038] In the above description, the rear roller 53 is an electromagnetic wheel.

[0039] In the above description, the sand falls down through the through hole 36 onto the front of the upper surface of the conveyor belt 54. The pulley inside the transmission mechanism 4 drives the front roller 53 to rotate, which in turn drives the conveyor belt 54 to rotate. At the same time, the two electromagnets 55 and the rear electromagnetic wheel are activated. During the conveying process of the sand on the surface of the conveyor belt 54, the magnetic impurities contained in the sand are attracted to the surface of the conveyor belt 54. Then, as the conveyor belt 54 rotates, the sand falls directly into the cavity of the hole 56 from the rear bend by gravity. The magnetic impurities are always attracted to the surface of the conveyor belt 54, and the conveyor belt 54 carries the magnetic impurities from the bottom to the front. When it reaches the bend of the front roller 53, the magnetic force disappears, and the magnetic impurities fall directly from the front of the conveyor belt 54.

[0040] Specifically, in order to achieve the purpose of air separation of sand, refer to Figure 5 In this scheme, the sorting component 6 includes a fixed box 61, which is fixedly connected to the lower rear side of the support frame 1. A storage box 65 is fixedly connected to the front end of the fixed box 61. A drop opening 63 is opened at the upper end of the fixed box 61. A fan 62 is fixedly connected to the upper side of the rear wall of the inner cavity of the fixed box 61. A pusher 64 is movably connected to the lower part of the inner cavity of the fixed box 61. Air holes 66 are opened at the upper rear end of the storage box 65 and the upper front end of the fixed box 61.

[0041] In the above process, the sand falls through the hole 56 into the inner cavity of the drop outlet 63, and then falls downward through the drop outlet 63 into the inner cavity of the pusher 64 for storage. At the same time, the blower 62 is started, and the blower 62 blows air through the sand during the falling process, thereby blowing the lighter impurities inside it through the air hole 66 into the inner cavity of the impurity storage box 65 to achieve the purpose of air separation.

[0042] It should be noted that the specific installation method, circuit connection method and control method of the fan 62 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
