Description

Technical Field

[0001] This invention relates to the field of casting material separation technology, and in particular to a casting separation and sorting processing line. Background Technology

[0002] Wear-resistant parts are formed by sand casting, such as wear-resistant balls or wear-resistant sections. After casting, the sand on the casting needs to be cleaned and the risers need to be separated. Currently, separation roller processing lines are mostly used to separate the castings.

[0003] For separating large-sized spheres (generally with an outer diameter greater than 50mm), the cast parts are directly fed into the rotary separator. The rotating separator separates the spheres by impact with the risers, without the need to insert media balls before outputting for sorting. For separating small-sized microspheres (generally with an outer diameter less than 40mm), large-sized media balls need to be placed into the rotary separator. The spheres rotate and impact with the media balls to efficiently remove residual sand from the castings. Different sizes of castings require different separation methods, necessitating multiple processing lines for different sizes of castings, which occupies a large space and results in low equipment utilization.

[0004] For example, patent CN216729389U discloses a rotary separator for casting materials, comprising a material separator body. One end of the material separator body has a feeding structure, and the other end has a discharging structure. The discharging structure is a conical cavity, with its large end connected to the material separator body. A set of discharge ports are located on the outer edge of the conical cavity. The discharge ports are circular holes, with a diameter larger than the outer diameter of the casting and smaller than the outer diameter of the medium balls. Because it incorporates medium balls within the rotary separator body, it is not suitable for separating and classifying large-sized casting balls. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a casting separation and sorting line that can separate castings of different sizes and specifications through a single separation cylinder, saving production space, with low overall investment costs and a wide range of applications.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] The casting separation and sorting line includes a rotary separation drum, a large ball and riser sorting mechanism, a micro ball and medium sorting mechanism, and a line conversion mechanism;

[0008] A feeding structure is provided at one end of the rotating separation drum, and a discharging structure is provided at the other end of the rotating separation drum;

[0009] The ball and riser sorting mechanism is used for vibration sorting of large balls and risers separated from the rotary separation drum;

[0010] The microsphere and media separation mechanism is used to vibrate and separate microspheres and media spheres separated from the rotary separation drum.

[0011] The line switching mechanism is used to transfer the material separated by the rotary separation drum to the large ball and riser sorting mechanism or the micro ball and medium sorting mechanism according to the different specifications of the casting.

[0012] Further:

[0013] The discharge structure is a ash screening mechanism, with a line switching mechanism set at one end of the ash screening mechanism, and a large ball and riser sorting mechanism and a micro ball and medium sorting mechanism set at both ends of the line switching mechanism, respectively.

[0014] The feeding structure includes a feeding hopper and a feeding gate located at the top of the feeding hopper. The lower end of the feeding hopper is connected to the inlet of the rotating separation drum.

[0015] The line switching mechanism is a reversible belt conveyor, and the large ball and riser sorting mechanism and the micro ball and medium sorting mechanism are respectively located on both sides of the rotating separation drum.

[0016] Below the ash screening mechanism is an ash discharge conveyor belt, and at one end of the ash discharge conveyor belt is a dust bucket elevator.

[0017] The ball and riser sorting mechanism is a vibrating conveying mechanism. The lower end of the vibrating conveying mechanism is provided with a ball chute and / or a ball output mechanism, and the upper end of the vibrating conveying mechanism is provided with a riser output mechanism.

[0018] The microsphere and media sorting mechanism is a vibrating screen, and a microsphere conveying mechanism and a media ball output mechanism are respectively provided on the vibrating screen. A media ball storage structure is provided at one end of the media ball output mechanism.

[0019] A large ball inspection platform and a large ball storage bin are provided at the upper end of the large ball output mechanism.

[0020] The medium ball storage structure is connected to the feeding structure and is provided with a valve plate structure and / or input roller for controlling the medium balls entering the feeding structure.

[0021] The vibrating screen is positioned between the microsphere conveying mechanism and the medium ball output mechanism.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] This casting separation and sorting line is rationally designed. Large-sized castings and risers are transported to a large ball and riser sorting mechanism on one side via a line switching mechanism, while small-sized castings and media balls are transported to a micro ball and media sorting mechanism on the other side via the line switching mechanism. When not in use, the media balls can be stored, simplifying control. It is applicable to the separation of castings of different sizes, has a wide range of applications, and high equipment utilization. Furthermore, it has a compact structure and is easy to arrange.

Detailed Implementation

[0031] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0032] like Figures 1 to 4 As shown, the casting separation and sorting line includes a rotary separation drum 4, a large ball and riser sorting mechanism 8, a micro ball and medium sorting mechanism 18, and a line conversion mechanism 7; a feeding structure is provided at one end of the rotary separation drum, and a discharging structure is provided at the other end of the rotary separation drum.

[0033] The large ball and riser sorting mechanism 8 is used to vibrate and sort the large balls and risers separated from the rotary separation drum; the micro ball and medium sorting mechanism 18 is used to vibrate and sort the micro balls and medium balls separated from the rotary separation drum; the line conversion mechanism is used to transfer the materials separated from the rotary separation drum to the large ball and riser sorting mechanism or the micro ball and medium sorting mechanism according to the different casting specifications.

[0034] The microsphere and media sorting mechanism 18 is a vibrating screen, and a microsphere conveying mechanism 17 and a media ball output mechanism 20 are respectively provided for the vibrating screen. A media ball storage structure is provided at one end of the media ball output mechanism. Large-sized castings and risers are conveyed to the large ball and riser sorting mechanism on one side through the line conversion mechanism for sorting. Small-sized castings and media balls are conveyed to the microsphere and media sorting mechanism on the other side through the line conversion mechanism for sorting. When the media balls are not in use, they can be stored. It is applicable to the separation of castings of different sizes and specifications, has a wide range of applications, and high equipment utilization.

[0035] The rotary separating drum, the large ball and riser sorting mechanism, the micro ball and medium sorting mechanism, and the line conversion mechanism are all sunken designs, installed on the underground foundation 23, and a dust collection device is installed in the sunken space to transform it into a workshop environment.

[0036] The feeding structure includes a feeding hopper 3 and a feeding gate 2 located at the top of the feeding hopper. A feeding opening and closing structure 1 is provided corresponding to the feeding gate. The feeding opening and closing structure can be a valve plate to control the feeding. The feeding gate is an openable cover plate structure. The feeding hopper is set at an angle, and the lower end of the feeding hopper is connected to the inlet of the rotating separation roller.

[0037] The discharge structure is a vibrating screen ash mechanism 6. The outlet of the rotating separation drum is equipped with an anti-splash rotating door 5. The vibrating screen ash mechanism is an inclined vibrating screen. One end of the inclined vibrating screen is set with the anti-splash rotating door 5, and the other end of the inclined vibrating screen is set with the line conversion mechanism 7. The material separated by the rotating separation drum is screened and then conveyed to the line conversion mechanism. The large ball and riser separation mechanism and the micro ball and medium separation mechanism are respectively set at both ends of the line conversion mechanism. The material is transferred to different separation mechanisms through the line conversion mechanism.

[0038] Below the ash screening mechanism is an ash discharge conveyor belt 22, and at one end of the ash discharge conveyor belt is a dust bucket elevator 19; furthermore, the ash discharge conveyor belt passes through a line switching mechanism and is connected to the lower end of the dust bucket elevator, resulting in a compact structure.

[0039] The line switching mechanism 7 is a reversible belt conveyor. The large ball and riser sorting mechanism is set at one end of the belt conveyor, and the micro ball and medium sorting mechanism is set at the other end of the belt conveyor. Furthermore, the large ball and riser sorting mechanism and the micro ball and medium sorting mechanism are respectively set on both sides of the rotating separation drum and the ash screening mechanism, which is compact and easy to arrange.

[0040] Alternatively, the line conversion mechanism 7 can be a receiving platform, with a rotatable pushing structure corresponding to the receiving platform. The large ball and riser separation mechanism and the micro ball and medium separation mechanism can be set on the same side of the receiving platform or at a certain angle. When separating and sorting large ball castings, the pusher plate of the pushing structure corresponds to the large ball and riser separation mechanism. When separating and sorting small ball castings, the pushing structure rotates at a certain angle, and the pusher plate corresponds to the micro ball and medium separation mechanism. This arrangement is flexible and the processing lines can be adjusted according to the workshop space.

[0041] Preferably, the switching mechanism is a forward and reverse belt conveyor, which is easy to control and runs stably.

[0042] The ball and riser sorting mechanism 8 is an inclined vibrating conveyor with an inclination angle of about 5 degrees. The lower end of the vibrator is provided with a ball chute 9 and / or a ball output mechanism 10, and the upper end of the vibrator is provided with a riser output mechanism 10. During sorting, the balls roll into the ball chute and are then conveyed out through the ball output mechanism. The sorted risers are conveyed out through the riser output mechanism.

[0043] A large ball inspection platform 11 and a large ball storage chamber are provided at the upper end of the large ball output mechanism; a riser storage chamber is provided at the upper end of the riser output mechanism.

[0044] The vibrating screen preferably uses a vibrating mesh screen. The outer diameter of the microspheres is generally less than 40mm, and the outer diameter of the media balls ranges from 80-120mm. The lower end of the microsphere conveying mechanism is located below the vibrating mesh screen, and the media ball output mechanism is located at one end of the vibrating mesh screen. The vibrating screen is located between the microsphere conveying mechanism and the media ball output mechanism, resulting in a compact structure.

[0045] The medium ball storage structure is connected to the feeding structure and is equipped with a valve plate structure and / or an input roller for controlling the entry of the medium balls into the feeding structure. Preferably, the medium ball storage structure is a medium ball storage and input roller 21; when separating and sorting large ball castings, medium balls are not required and are stored in the medium ball storage structure; when separating and sorting small ball castings, medium balls are required, and the medium ball storage and input roller operates to circulate the sorted medium balls into the feeding hopper.

[0046] Furthermore, sufficient time is provided for microsphere sorting; a microsphere storage chamber 13 is provided corresponding to the microsphere conveying mechanism, and a solenoid valve is installed at the lower port of the microsphere storage chamber; a microsphere output mechanism 14 is provided corresponding to the microsphere storage chamber, with its lower end corresponding to the lower port of the microsphere storage chamber, and a multi-stage screening mechanism 16 and a microsphere inspection platform 15 are provided at the upper end of the microsphere output mechanism. Belt conveyors are preferred for each conveying mechanism due to their relatively low cost.

[0047] The above description is merely an illustration of preferred embodiments of the present invention, and the above technical features can be arbitrarily combined to form multiple embodiments of the present invention.
