Description

Technical Field

[0001] This utility model relates to the field of cast steel parts technology, specifically to a waste screening and collection device for cast steel parts processing. Background Technology

[0002] Cast steel parts are parts made of cast steel, which have similar properties to cast iron, but are stronger than cast iron.

[0003] During the processing of cast steel parts, there will be defective products (such as waste generated from casting, waste generated from the separation of the mold and the casting, waste caused by casting defects, etc.), which need to be crushed and screened. In the existing technology, the particle size of the crushed cast steel parts is generally controlled by screening machine, so that larger waste materials can be directly remelted, while smaller waste materials may need to be briquetized first to facilitate transportation and melting.

[0004] However, the waste from cast steel parts may contain steels of different compositions, such as carbon steel waste and alloy steel waste. Existing screening technologies mainly focus on screening waste based on particle size, making it difficult to separate cast steel parts of different compositions according to their composition. As a result, metal elements may not be fully utilized during waste recycling, leading to waste, and may also increase recycling costs and difficulties, and reduce recycling efficiency. Utility Model Content

[0005] In view of this, the present invention provides a screening and collection device for waste materials from the processing of cast steel parts. The device can be equipped with a screening cylinder and a metal wire wrapped around its outside, in conjunction with a power supply and a drive mechanism. When the metal wire coil is energized, the screening cylinder is magnetized, and the rotating screening cylinder separates alloy steel waste from carbon steel waste. This can avoid waste during waste recycling, reduce recycling costs and difficulties, and improve recycling efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides a screening and collection device for waste materials from the processing of cast steel parts, including a support plate, a driving mechanism is provided on the upper part of the support plate, a screening cylinder is provided above the driving mechanism, the driving mechanism is used to drive the screening cylinder above it to rotate, and a metal wire is evenly wound on the outer wall of the screening cylinder. The metal wire can be made of copper, and both ends of the metal wire are connected to a power supply. The power supply is set to an adjustable power supply.

[0007] Both ends of the screening cylinder are connected to drive discs, which are fixedly connected to both ends of the screening cylinder. Drive grooves are opened on the outer walls of both drive discs. The drive grooves can be integrally formed with the drive discs by casting with a mold during manufacturing. A protective shell is set between the two drive discs. Both ends of the protective shell are connected between the two drive discs by bolts. The power supply is connected to the outer wall of the protective shell through a mounting plate, which is fixedly connected to the outer wall of the protective shell.

[0008] Multiple guide strips are evenly arranged on the inner wall of the screening cylinder. The multiple guide strips are fixedly connected to the inner wall of the screening cylinder, and there is a certain gap between the multiple guide strips. The multiple guide strips are all set as spiral structures.

[0009] The drive mechanism includes four support frames symmetrically arranged on the upper part of the support plate. All four support frames are bolted to the upper part of the support plate. Each pair of support frames corresponds to the area below each drive slot, meaning there are two support frames symmetrically arranged below each drive slot. Each support frame is rotatably connected to a drive wheel. Each pair of drive wheels is connected to a transmission rod. Each transmission rod passes through each pair of drive wheels and is fixedly connected to the drive wheels. Each transmission rod is rotatably connected to the support frame via a bearing. One end of each transmission rod is connected to a belt, meaning that one end of each transmission rod is fitted with a pulley. The belt is mounted on the two pulleys to drive the two transmission rods. One end of one transmission rod is connected to the output shaft of the motor. The output shaft of the motor is connected to the transmission rod via a coupling.

[0010] A guide plate is provided on one side of the discharge port of the screening cylinder. The guide plate is in contact with the discharge port of the screening cylinder but is not connected to it. The guide plate is connected to the upper part of the support plate through a fixing plate. The lower part of the guide plate is fixedly connected to the fixing plate. The fixing plate is connected to the upper part of the support plate by bolts.

[0011] Two storage boxes are set on one side of the support plate and below the guide plate. The two storage boxes are placed on the ground and connected by magnetic pieces. That is, there are magnetic pieces on the facing surfaces of the two storage boxes, and they are connected by attraction.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. By using a screening cylinder and its externally wound metal wire, along with a power supply and drive mechanism, the screening cylinder can be magnetized by energizing the metal wire coil. The rotating screening cylinder separates alloy steel waste from carbon steel waste, thereby avoiding waste during waste recycling, reducing recycling costs and difficulties, and improving recycling efficiency.

[0014] 2. The protective casing can prevent the risk of electric shock and avoid harm to the health of workers.

[0015] 3. The set drive mechanism can drive the screening cylinder to rotate through multiple drive wheels, and with the help of multiple spiral guide bars, the material can be screened and guided to the other side of the screening cylinder for discharge. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0028] like Figure 2 , 3 As shown: A waste screening and collection device for cast steel parts includes a support plate 101, which provides stable support for all components. A drive mechanism is installed on the upper part of the support plate 101, which drives the screening cylinder 102 and its components to rotate, thereby increasing the screening rate of the cast steel waste. The screening cylinder 102 is installed above the drive mechanism, allowing the cast steel waste to be screened and processed, separating different fragments containing different metals. The drive mechanism drives the screening cylinder 102 to rotate. Metal wires 103 are evenly wound on the outer wall of the screening cylinder 102. 3. Thus, when the coil is energized, the screening cylinder 102 inside is magnetized by the magnetic field formed by the energized metal wire 103 coil, thereby enhancing the magnetism of the screening cylinder 102. The metal wire 103 can be made of copper, which gives it good conductivity, reduces energy loss, and minimizes performance degradation and energy waste caused by heat. Both ends of the metal wire 103 are connected to the power supply 104, allowing the metal wire 103 to be energized. The power supply 104 is set as an adjustable power supply, which allows the output voltage and current to be adjusted within a certain range. The strength of the magnetic field can be controlled by controlling the magnitude of the current, thus controlling the magnetic strength of the screening cylinder. The metal wire 103 can be bare wire.

[0029] like Figure 1 , 2As shown: Both ends of the screening cylinder 102 are connected to drive discs 106. The drive discs 106 are designed to have drive grooves 107. The drive discs 106 are fixedly connected to both ends of the screening cylinder 102, making the connection structure more stable. Drive grooves 107 are provided on the outer walls of both drive discs 106. These drive grooves 107 work in conjunction with the drive mechanism to drive the screening cylinder 102, further enhancing its screening and guiding capabilities. The drive grooves 107 and drive discs 106 can be integrally formed by casting with a mold during manufacturing, making the connection structure more stable. A protective shell 301 is provided between the two drive discs 106 to prevent the risk of electric shock. The outer side of the protective shell 301... Multiple heat dissipation holes can be opened on the wall to facilitate heat dissipation of the metal wires 103 wound on the outer wall of the screening cylinder 102. Both ends of the protective shell 301 are bolted between the two drive discs 106, so that the protective shell 301 can be easily disassembled and installed when maintenance or replacement is required. The power supply 104 is connected to the outer wall of the protective shell 301 through the mounting plate 105, so that the power supply 104 can be firmly connected to the outer wall of the protective shell 301 through the mounting plate 105. The power supply 104 is bolted to the mounting plate 105, so that the power supply 104 can be easily disassembled and installed when maintenance or replacement is required. The mounting plate 105 is fixedly connected to the outer wall of the protective shell 301, so that the mounting plate 105 and its components can be stably supported.

[0030] like Figure 2 , 4 As shown: Multiple guide bars 201 are evenly arranged on the inner wall of the screening cylinder 102. The multiple guide bars 201 allow cast steel waste added to one side of the screening cylinder 102 to move towards the discharge port when the screening cylinder 102 rotates, thus enabling the cast steel waste to be screened according to the different metal elements it contains. The multiple guide bars 201 are all fixedly connected to the inner wall of the screening cylinder 102, making the connection structure more stable. A certain gap is also spaced between the multiple guide bars 201, allowing waste containing magnetic components to remain between two adjacent guide bars 201 and not move towards the discharge port of the screening cylinder 102 due to the guidance of multiple guide bars 201. The multiple guide bars 201 are all designed with a spiral structure, which guides waste without magnetic components to move to the discharge port of the screening cylinder 102 for falling and collection.

[0031] like Figure 1 , 5As shown: The drive mechanism includes four support frames 401 symmetrically arranged on the upper part of the support plate 101. The support frames 401 provide stable support for the drive wheels 402 mounted on them, allowing the drive wheels 402 to rotate. All four support frames 401 are bolted to the upper part of the support plate 101, facilitating disassembly and assembly of the support frames 401 and their components for maintenance or replacement. Two support frames 401 are arranged below each drive slot 107, meaning two support frames 401 are symmetrically arranged below each drive slot 107. This allows the drive wheels 402 on the support frames 401 to provide stable support for the screening cylinder 102 and the drive disc 106 above, and also enables rotation... The drive groove 107 drives the drive disc 106, which in turn drives the screening cylinder 102 to screen the casting steel waste inside. Each support frame 401 is rotatably connected to a drive wheel 402. The drive wheel 402 supports the screening cylinder 102 and drives it to rotate. A transmission rod 403 is connected to every two drive wheels 402. The transmission rod 403 drives the drive wheel 402 to rotate, which in turn drives the drive wheel 402 to rotate. Therefore, the rotation of multiple drive wheels 402 can drive the screening cylinder 102 to rotate.

[0032] like Figure 5 As shown: Each transmission rod 403 passes through every two drive wheels 402 and is fixedly connected to the drive wheels 402, so that the transmission rod 403 can drive the drive wheels 402 to rotate when it rotates. Each transmission rod 403 is rotatably connected to the support frame 401 via a bearing, thus providing support for the transmission rod 403 and preventing it from jamming during rotation. Two transmission rods 403 are connected at one end by a belt, allowing both transmission rods 403 to rotate simultaneously via a single motor 404, thereby saving energy. This design saves costs and installation space. Each of the two transmission rods 403 has a pulley at one end, and a belt on each pulley drives the two transmission rods 403. This allows rotation of one transmission rod 403 to rotate the other. One end of one transmission rod 403 is connected to the output shaft of a motor 404, which is connected to the transmission rod 403 via a coupling. Thus, rotation of the motor 404's output shaft drives one of the transmission rods 403 to rotate.

[0033] like Figure 2 , 5As shown: A guide plate 501 is provided on one side of the discharge port of the screening cylinder 102. The guide plate 501 allows the cast steel waste separated by screening to slide down into the corresponding collection box 601 through the guide plate 501. The guide plate 501 is in contact with the discharge port of the screening cylinder 102 but not connected to it, so as to avoid the guide plate 501 from tilting or tearing when the screening cylinder 102 rotates, and thus avoid the guide plate 501 and the screening cylinder 102 from restraining each other. The guide plate 501 is connected to the upper part of the support plate 101 through the fixing plate 502, so as to make its support structure more stable. The lower part of the guide plate 501 is fixedly connected to the fixing plate 502, so as to make its connection structure more stable. The fixing plate 502 is bolted to the upper part of the support plate 101, so that the fixing plate 502 on the support plate 101 can be easily installed and removed.

[0034] like Figure 1 As shown: Two collection boxes 601 are provided on one side of the support plate 101 and below the guide plate 501. The two collection boxes 601 are designed so that one collection box can collect carbon steel scrap and the other can collect alloy steel scrap. The two collection boxes 601 are placed on the ground to make the support structure more stable. The two collection boxes 601 are connected by magnetic pieces, which allows them to be moved and quickly replaced to catch the scrap on the guide plate 501. Magnets are provided on the facing surfaces of the two collection boxes 601, and they are connected by attraction, which allows the two collection boxes 601 to be connected and quickly assembled and disassembled.

[0035] In use, turn on the power supply 104 and adjust the current of the power supply 104 according to the size of the batch of cast steel waste to be screened, so that the magnetic strength of the screening cylinder 102 can be controlled. Add the crushed cast steel waste from one side of the screening cylinder 102 and start the mechanism to rotate multiple drive wheels 402, causing the screening cylinder 102 to rotate accordingly. At this time, the cast steel waste inside the screening cylinder 102 will rotate, and under the guidance of multiple guide bars 201, the cast steel waste will be... Steel scrap can move to the other side of the screening cylinder 102, while carbon steel scrap has strong magnetism and will be adsorbed on the inner wall of the screening cylinder 102, thus preventing it from falling off. Furthermore, if too much cast steel scrap is poured in, the carbon steel scrap that is not adsorbed will also be adsorbed between every two non-adjacent guide bars 201 under the guidance of multiple non-connected guide bars 201, or it will be directly adsorbed on the inner wall of the screening cylinder 102 when poured in, thus preventing it from being discharged from the screening cylinder 102 due to the rotation of the screening cylinder 102 and the guidance of multiple guide bars 201.

[0036] Alloy steel scrap is non-magnetic or has very weak magnetism. When the screening cylinder 102 rotates, it is guided by the rotation of the screening cylinder 102 and multiple guide bars 201 to be discharged to the other side of the screening cylinder 102 and collected by the collection box 601. After the alloy steel scrap is collected, the power supply 104 is turned off, and the magnetism will gradually weaken. At this time, the rotating screening cylinder 102 and guide bars 201 can guide the carbon steel scrap and move another collection box 601 below the guide plate 501 to collect the carbon steel scrap. Therefore, alloy steel scrap and carbon steel scrap castings can be separated according to their composition differences, thereby avoiding waste during scrap recycling, reducing recycling costs and difficulties, and improving recycling efficiency.

[0037] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
