Description

Technical Field

[0001] This utility model belongs to the technical field of waste treatment devices, specifically relating to a waste treatment device for workpiece cutting. Background Technology

[0002] In the field of machining, workpiece cutting is a common processing step. The cutting process not only generates a large amount of cutting waste but also produces harmful metal dust due to high temperatures and friction. Currently, most cutting equipment lacks effective waste disposal capabilities, typically relying on simple collection hoods and chip collection carts for unified collection.

[0003] This method has obvious drawbacks: First, the lightweight dust disperses everywhere, polluting the working environment, endangering the health of operators, and making subsequent cleanup difficult; second, existing waste processing equipment is not convenient for screening waste or debris of different volumes, and the smaller waste after screening is mostly a mixture of metal particles, debris, and dust, with different types of ferromagnetic and non-ferromagnetic metals mixed together, resulting in low recycling value. Additional manpower and equipment are required for subsequent sorting, increasing recycling costs and processing steps, and it is not convenient to use when cutting workpieces. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a waste processing device for workpiece cutting. This waste processing device for workpiece cutting can directly suck away most of the dust at the cutting source, effectively preventing dust diffusion. Through the vibrating screening mechanism and the magnetic separation screening mechanism, different types of metal waste are automatically classified and collected into different collection boxes, which greatly improves the purity and recycling value of the waste and saves additional sorting costs.

[0005] A waste disposal device for workpiece cutting includes a collection hood and a storage box. Negative pressure dust extraction mechanisms are installed on the top of both sides of the collection hood to suck up dust from the cutting area. A mesh plate is fixedly connected to the top of the inside of the collection hood, and a vibrating screening mechanism is installed inside the collection hood to vibrate and screen the cutting waste. A storage box is fixedly connected to the bottom of the collection hood, corresponding to the bottom of the vibrating screening mechanism, and a collection container is inserted inside the storage box. A classification and storage mechanism, vertically corresponding to the vibrating screening mechanism, is fixedly connected to the bottom of the collection hood, and a magnetic separation screening mechanism is installed inside the classification and storage mechanism to separate magnetic metals from non-magnetic metals.

[0006] Preferably, the negative pressure dust collection mechanism includes a dust collection hood, a diversion negative pressure pipe, and a connecting pipe. The number of dust collection hoods is several, and all dust collection hoods are fixedly installed on the top of the outside of the collection hood and communicate with the inside of the collection hood. The air inlet end of the diversion negative pressure pipe is connected to several dust collection hoods, and its air outlet end is connected to the connecting pipe. The connecting pipe can be connected to an external negative pressure pipeline.

[0007] Preferably, the vibrating screening mechanism includes a screen, springs, and a vibrating motor. Springs are fixedly connected to both sides and the top of the screen, and the ends of the springs away from the screen are fixedly connected to the inner wall of the collection hood. The screen is set in an inclined state inside the collection hood, and the vibrating motor is fixedly installed on the lower surface of the screen near the top.

[0008] Preferably, the screen is in the shape of an isosceles trapezoid with the shorter side facing the bottom of the collection cover and close to the storage box. The collection cover has a discharge port at the part corresponding to the shorter side of the screen. The bottom of the collection cover is an open structure, and the storage box is placed outside the discharge port.

[0009] Preferably, the sorting and storage mechanism includes an outer box, a conical guide shroud, a first storage box, and a second storage box. The conical guide shroud is fixedly connected to the top of the outer box and the outer box is fixedly connected to the bottom of the collection shroud. The first storage box and the second storage box are respectively installed on both sides of the bottom of the outer box and are symmetrically arranged with the vertical center line of the outer box as the axis of symmetry.

[0010] Preferably, the magnetic separation and screening mechanism includes a drive motor, a permanent magnet drum, and a baffle scraper. The permanent magnet drum is horizontally rotatably connected inside the outer casing and connected to the output end of the drive motor via a spline. The drive motor is fixedly installed in the middle of the outer casing on the side away from the storage box. The permanent magnet drum is vertically aligned with the bottom of the conical guide shroud. The baffle scraper is fixedly connected to the inner side wall of the outer casing and its bottom end covers the outside of the permanent magnet drum.

[0011] Preferably, the top sides of the first and second storage boxes that are close to each other are adapted to the outside of the permanent magnet roller, and the top sides of the first and second storage boxes that are close to each other are provided with slots for the magnetic metal on the permanent magnet roller to pass through. The baffle scraper is fixedly connected to the inner side wall of the outer box near the second storage box.

[0012] The beneficial effects of the above technical solution are as follows:

[0013] This waste disposal device for workpiece cutting utilizes negative pressure dust extraction mechanisms on both sides of the collection hood to directly remove most of the dust at the cutting source, effectively preventing dust diffusion, significantly improving air quality in the work area, and protecting the health of operators. The vibrating screening mechanism automatically separates larger cutting waste from smaller debris and dust. Larger pieces are guided to one side for collection, while smaller materials fall through the screen and are then separated by a magnetic separation mechanism that adsorbs and separates ferromagnetic metals from the falling mixed waste. Non-magnetic metals fall directly to the bottom, allowing different types of metal waste to be automatically classified and collected into different storage boxes. This greatly improves the purity and recycling value of the waste, saving additional sorting costs. The entire process is automatic and continuous, requiring no manual intervention, significantly improving waste disposal efficiency and making it more convenient to use during workpiece cutting.

Detailed Implementation

[0020] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 5 The embodiments are described in detail below.

[0021] This embodiment provides a waste disposal device for workpiece cutting, as shown in the attached figure. Figure 1As shown, the system includes a collection cover 1 and a storage box 2. Both ends of the collection cover 1 can be fixedly installed below the cutting part by bolts, vertically corresponding to the main cutting part, so that the waste generated during cutting can fall directly into the collection cover 1. The top of both sides of the collection cover 1 is provided with a negative pressure dust suction mechanism 3 to suck up the dust from the cutting part. Specifically, the negative pressure dust suction mechanism 3 includes a dust suction hood 301, a diversion negative pressure pipe 302, and a connecting pipe 303. There are several dust suction hoods 301, and all of them are fixedly installed outside the collection cover 1. The top of the side is connected to the inside of the collection hood 1. The air inlet of the diversion negative pressure pipe 302 is connected to several dust collection hoods 301 and its air outlet is connected to the connecting pipe 303. The connecting pipe 303 can be connected to the external negative pressure pipeline. The external negative pressure equipment generates negative pressure suction in the connecting pipe 303 and the diversion negative pressure pipe 302, thereby generating negative pressure in the multiple dust collection hoods 301, which can suck away most of the dust generated during cutting, effectively prevent dust diffusion, significantly improve the air quality of the working area, and protect the health of the operators.

[0022] In one optional embodiment, the number of negative pressure dust collection mechanisms 3 can be two sets. The two sets of negative pressure dust collection mechanisms 3 are respectively arranged on the top of both sides of the collection hood 1 and are symmetrically arranged with the vertical center line of the collection hood 1 as the axis of symmetry. They can suck up dust from both sides of the cutting part, making the suction range larger and the dust collection effect better.

[0023] As attached Figure 2 and 4 As shown, a mesh plate 4 is fixedly connected to the top of the inside of the collection hood 1. The mesh plate 4 can receive the larger waste materials cut off, preventing them from falling onto the vibrating screening mechanism 5 below and causing blockage. The mesh plate 4 can play a preliminary screening role. The inside of the collection hood 1 is equipped with a vibrating screening mechanism 5 for vibrating screening of the cut waste materials. Specifically, the vibrating screening mechanism 5 of this utility model includes a screen 501, a spring 502, and a vibrating motor 503. Springs 502 are fixedly connected to both sides and the top of the screen 501, and the ends of the springs 502 away from the screen 501 are fixedly connected to the inner wall of the collection hood 1. The screen 501 is connected to the inner wall of the collection hood 1 by the springs 502. Inside the collection hood 1, the spring 502 ensures that the screen 501 is in an active state. The screen 501 is set in an inclined state inside the collection hood 1. The vibration motor 503 is fixedly installed on the lower surface of the screen 501 near the top. The operation of the vibration motor 503 can drive the screen 501 to generate high-frequency vibration, thereby vibrating the waste falling on the screen 501. Waste and debris smaller than the mesh of the screen 501 fall into the sorting and collecting mechanism 7 below, while waste larger than the mesh of the screen 501 rolls down the screen 501 under vibration into the collection box 6 in the collection box 2, thereby achieving further sorting and collection of waste and reducing subsequent processing steps.

[0024] In one optional embodiment, the screen 501 is an isosceles trapezoid with its shorter side facing the bottom of the collection cover 1 and close to the storage box 2. The collection cover 1 has a discharge port 9 at the part corresponding to the shorter side of the screen 501. The bottom of the collection cover 1 is an open structure. The storage box 2 is placed outside the discharge port 9. Large volume waste on the screen 501 can be discharged from the discharge port 9 under vibration and fall into the collection box 6. The collection box 6 can be removed separately, which is convenient for periodically cleaning the waste in the collection box 6.

[0025] A storage box 2 is fixedly connected to the bottom of the collection cover 1 at the location corresponding to the bottom of the vibrating screening mechanism 5, and a collection box 6 is inserted into the inside of the storage box 2. A classification and storage mechanism 7, vertically corresponding to the vibrating screening mechanism 5, is fixedly connected to the bottom of the collection cover 1. (See attached diagram for details.) Figure 3 and 5 As shown, the sorting and storage mechanism 7 includes an outer box 701, a conical guide hood 702, a first storage box 703, and a second storage box 704. The conical guide hood 702 is fixedly connected to the top of the inner part of the outer box 701, and the outer box 701 is fixedly connected to the bottom of the collection cover 1. The conical guide hood 702 can guide the small-volume waste and debris that have passed through the sieve 501, so that all the debris can be discharged from the bottom of the conical guide hood 702 to the magnetic separation sieve mechanism 8 below. The first storage box 703 and the second storage box 704 are respectively installed on both sides of the bottom of the outer box 701 and are symmetrically arranged with the vertical center line of the outer box 701 as the axis of symmetry. The first storage box 703 and the second storage box 704 can be taken out horizontally, which facilitates the collection and processing of the waste inside them.

[0026] The internal structure of the sorting and storage mechanism 7 is equipped with a magnetic separation and sieving mechanism 8 that can separate magnetic metals from non-magnetic metals, as detailed in the attached diagram. Figure 3 and 5As shown, the magnetic separation screening mechanism 8 includes a drive motor 801, a permanent magnet drum 802, and a baffle scraper 803. The permanent magnet drum 802 is horizontally rotatably connected inside the outer casing 701 and is connected to the output end of the drive motor 801 via a spline. The drive motor 801 is fixedly installed in the middle of the outer casing 701 on the side away from the storage box 2. The permanent magnet drum 802 is vertically aligned with the bottom of the conical guide shroud 702. The drive motor 801 drives the permanent magnet drum 802 to rotate clockwise at a uniform speed, which can attract ferromagnetic metals from the mixed metal waste falling from the conical guide shroud 702. The ferromagnetic metals can be attracted to the permanent magnet drum 802 and rotate with it, while the non-ferromagnetic metals will fall directly to the side under their own gravity when rotated by the permanent magnet drum 802. The waste is placed into the first collection box 703 below. The baffle scraper 803 is fixedly connected to the inner wall of the outer box 701 and its bottom end covers the outside of the permanent magnet roller 802. The baffle scraper 803 can prevent non-magnetic metals and waste from falling directly into the second collection box 704 from the side of the permanent magnet roller 802. When the ferromagnetic metal rotates towards the baffle scraper 803 as driven by the permanent magnet roller 802, the baffle scraper 803 is attached to the outside of the permanent magnet roller 802. Therefore, the ferromagnetic metal adsorbed on the outer surface of the permanent magnet roller 802 will be scraped off by the baffle scraper 803 and fall into the second collection box 704 below. In this way, different types of waste can be classified and collected into different collection boxes, which greatly improves the purity and recycling value of the waste and saves additional sorting costs.

[0027] In one optional embodiment, the top edges of the first storage box 703 and the second storage box 704, which are close to each other, are adapted to the exterior of the permanent magnet roller 802. Both the top edges of the first storage box 703 and the second storage box 704 have slots for the magnetic metal on the permanent magnet roller 802 to pass through. When the ferromagnetic metal is attracted to the outer surface of the permanent magnet roller 802 and rotates with it, it can smoothly pass through the slots at the top of the first storage box 703 and the second storage box 704, avoiding any movement of the ferromagnetic waste material. Impact: The baffle scraper 803 is fixedly connected to the inner wall of the outer casing 701 near the second storage box 704. The baffle scraper 803 is inclined. After the ferromagnetic waste is scraped off by the baffle scraper 803, it can move along the lower surface of the baffle scraper 803 under the push of the ferromagnetic waste behind it until it is far away from the permanent magnet roller 802. When the magnetic force of the permanent magnet roller 802 is less than its own weight, the waste will fall vertically into the second storage box 704 below, thereby collecting the ferromagnetic metal.

[0028] Both the vibration motor 503 and the drive motor 801 are electrically connected to the external control unit and are electrically connected to the external circuit through wires.

[0029] In summary, the waste disposal device for workpiece cutting operates as follows:

[0030] 1. Fix the collection cover 1 to the bottom of the cutting part of the cutting equipment with bolts to ensure that the waste generated by cutting can fall directly into the collection cover 1, and connect the connecting pipe 303 to the external negative pressure pipeline system;

[0031] 2. Then turn on the external negative pressure device to make the negative pressure dust collection mechanism 3 start working. At this time, the dust collection hood 301 will generate suction to suck up the dust generated during cutting. Simultaneously start the vibration motor 503 and the drive motor 801 to make the screen 501 vibrate at high frequency and the permanent magnet drum 802 rotate clockwise at a uniform speed.

[0032] 3. Waste generated from workpiece cutting falls into collection hood 1. Most of the dust generated from cutting is immediately sucked in by the dust suction hoods 301 on both sides of the top of collection hood 1 and discharged into the external dust removal system through the diversion negative pressure pipe 302 and the connecting pipe 303. The falling waste first falls on the mesh plate 4. Smaller debris and dust fall through the mesh plate 4, while larger waste is intercepted by the mesh plate 4.

[0033] 4. Waste passing through the mesh plate 4 falls onto the high-frequency vibrating screen 501. Debris and waste smaller than the mesh openings of the screen 501 pass through the mesh openings under the vibration and fall into the cone-shaped guide shroud 702 below. Waste larger than the mesh openings of the screen 501 moves towards the discharge port 9 under the vibration of the inclined screen and is finally discharged through the discharge port 9, falling into the collection box 6 inside the collection box 2.

[0034] 5. The mixed metal debris falling from the bottom of the conical guide shroud 702 falls evenly onto the uniformly rotating permanent magnet drum 802. The non-ferromagnetic metals are not affected by the magnetic force and fall directly into the first collection box 703 located below when they rotate to the side driven by the permanent magnet drum 802. The ferromagnetic metals are attracted by the permanent magnet drum 802 and are scraped off by the baffle scraper 803 when the drum rotates to the position of the baffle scraper 803. The scraped ferromagnetic metals move along the lower surface of the baffle scraper 803 and fall into the second collection box 704 located below after leaving the magnetic dominance area, thus performing fine sorting and processing of the waste.

[0035] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
