Description

Technical Field

[0001] This invention relates to the field of waste screening technology, and in particular to a large-scale waste screening and processing equipment. Background Technology

[0002] In the process of large-scale waste disposal, since the waste varies in size, it is necessary to screen the waste to separate large and small waste for different processing.

[0003] Chinese patent CN215313821U discloses a screening device for large construction waste, which solves the problem that the filter plates of current construction waste screening devices on the market cannot be tilted at an adjustable angle, leading to filter plate blockage and frequent cleaning. The device includes a front baffle and a filter plate. Support frames are fixedly connected to both ends of the front baffle, and a stabilizing frame is fixedly connected to the support frame on the side away from the front baffle. Side baffles are fixedly connected to the sides of the filter plate, and bottom plates are fixedly connected to both ends of the side baffles. A first motor is fixedly connected to the top of the bottom plate. A connecting plate is fixedly connected between the two support frames, and a groove is formed on the top of the connecting plate. The inner cavity of the groove has a sliding plate that can slide up and down within the groove. Although the above patent can screen large waste, it can only screen based on the size of the waste. Furthermore, the waste contains metal waste, which has recycling value, and the inability to screen the metal waste affects the screening effect.

[0004] The present invention aims to solve the problems existing in the above-mentioned patents. To this end, a large-scale waste screening and processing equipment is proposed that can screen waste by size and metal waste at the same time, thereby improving the screening effect. Summary of the Invention

[0005] To overcome the shortcomings of the aforementioned patents, which can screen large waste but only by size, and which also contain metal waste with recycling value but cannot be screened, thus affecting the screening effect, this invention provides a large waste screening and processing device that can screen waste by size and metal waste simultaneously, thereby improving the screening effect.

[0006] This invention is achieved through the following technical solution:

[0007] A large-scale waste screening and processing device includes a shell and a feed hopper connected to the shell. A discharge hopper I is connected to the bottom of the shell, and a series of discharge hoppers II are connected to the right side of the bottom of the shell. An electric lifting frame is installed on the shell. The device also includes a screening component, a conveying component, magnetic plates I and II, a drive motor, and a material blocking component. The screening component, mounted on the electric lifting frame, is used to screen large waste. Conveying components are symmetrically arranged inside the shell; the lower conveying component corresponds to the feed inlet of discharge hopper I, and the lower conveying component corresponds to the feed inlet of discharge hopper II. Magnetic plates I and II are fixedly connected inside the shell to the inner side of the upper conveying component and the lower conveying component, respectively. A drive motor is installed on the outer side of the shell, and the output shaft of the drive motor is fixedly connected to the end of the conveying component. The drive motor drives the conveying component to rotate, and the rotation of the conveying component causes the metal waste to rotate via magnetic plates I and II, thus separating and collecting the metal waste. The material blocking component is installed between the shell and the electric lifting frame to intermittently block the waste.

[0008] Further explanation: The screening assembly includes movable rods that slide through both sides of the electric lifting frame at even intervals. An inclined screen plate is fixed between the ends of all the movable rods. The screen plate is located inside the electric lifting frame to screen the waste. The right side of the screen plate corresponds to the feed inlet of the discharge hopper II. Vibration motors are installed at even intervals at the bottom of the screen plate. Connecting springs are connected at even intervals between the screen plate and the electric lifting frame.

[0009] Further explanation: The material blocking assembly includes a baffle plate that is vertically slidably connected to the inner side of the housing at uniform intervals. The baffle plate slides through the screen plate to intermittently block the waste. The baffle plate has symmetrical grooves. Electromagnetic rods corresponding to the grooves of the baffle plate are fixedly connected to both sides of the electric lifting frame at uniform intervals to drive the baffle plate to move upward. A button located below the electric lifting frame is fixedly connected to the inner side of the housing. The button is electrically connected to the electromagnetic rod and is at the same level as the baffle plate.

[0010] To further explain, guide rods are fixedly attached at even intervals on the inner side of the housing, and the guide rods slide through the baffle plate to guide the baffle plate.

[0011] Further explanation: The large-scale waste screening and processing equipment also includes a cleaning component. The cleaning component includes guide rods fixed to the inner sides of discharge hopper I and discharge hopper II. An n-shaped plate is slidably fitted between the guide rods on each side. A brush that contacts the conveying component is fixed on the n-shaped plate to remove the waste attached to the conveying component. Both discharge hopper I and discharge hopper II are equipped with triggering components to drive the n-shaped plate to move back and forth.

[0012] Further explanation: The triggering component includes a rotating shaft that is rotatably connected to discharge hopper I and discharge hopper II. The rotating shaft is driven by a synchronous belt assembly. A drive cylinder is symmetrically fixed on the rotating shaft. An inclined groove is opened on the outside of the drive cylinder. The drive cylinder rotatably passes through an n-shaped plate. A convex ball located in the inclined groove of the drive cylinder is fixed to the inside of the n-shaped plate.

[0013] To further explain, the large-scale waste screening and processing equipment also includes observation windows that are symmetrically fixed and inserted through the shell.

[0014] To further explain, the large-scale waste screening and processing equipment also includes a sealing baffle fixed to the inside of the shell. The sealing baffle is located above the electric lifting frame to block the gap between the screen plate and the electric lifting frame.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. The waste is poured into the housing through the feed hopper, and the screen plate screens the waste. At the same time, the electric lifting frame is activated to move the screen plate up and down. The screen plate moves up and down and throws the waste up. The upper conveying component uses magnetic plate I to adsorb and remove metal waste from large waste, while the lower conveying component adsorbs and removes metal waste from small waste. This process is repeated to continuously screen the waste by size and also to screen metal waste, thereby improving the screening effect.

[0017] 2. Under the action of the baffle plate, whenever the screen plate screens the garbage, the baffle plate can intermittently block the garbage on the screen plate, so that the garbage stays on the screen plate for a longer time to be screened, thereby ensuring that the garbage is fully screened.

[0018] 3. Under the action of the brush, whenever the conveying component rotates, the brush moves back and forth to remove the garbage attached to the conveying component, which can prevent the garbage attached to the surface of the conveying component from affecting the subsequent adsorption of metal garbage, thereby ensuring the effectiveness of the conveying component.

Detailed Implementation

[0030] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, and lateral, also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0031] Example: A large-scale waste screening and processing equipment, please refer to [link / reference]. Figures 1-7As shown, the device includes a housing 1 and a feed hopper 2 connected to the top left side of the housing 1. The housing 1 is inclined. A discharge hopper I 3 is connected to the bottom left side of the housing 1, and three discharge hoppers II 4 are connected to the bottom right side of the housing 1. The three discharge hoppers II 4 are arranged in sequence. An electric lifting frame 41 is installed on the housing 1. The electric lifting frame 41 consists of cylinders and a lifting frame. Four cylinders are fixed to the housing 1, and the lifting frame is fixed between the ends of the telescopic rods of the four cylinders. The lifting frame is located inside the housing 1. The device also includes a screening assembly, a conveying assembly 8, a magnetic plate I 9, and a magnetic plate II 9. 91. Drive motor 92 and material blocking assembly. The screening assembly is installed on the electric lifting frame 41. When the screening assembly is in operation, it can screen large waste. Conveying assemblies 8 are symmetrically arranged on the upper and lower sides of the inner side of the housing 1. The conveying assemblies 8 are located on the upper and lower sides of the electric lifting frame 41. The conveying assemblies 8 consist of a conveyor belt and two conveying rollers. The two conveying rollers are rotatably connected between the front and rear sides of the housing 1. The conveyor belt is wrapped between the two conveying rollers. The left side of the lower conveying assembly 8 corresponds to the feed inlet of the discharge hopper I3. The right side corresponds to the feed inlet of the left discharge hopper II4, and the right side of the upper conveyor assembly 8 corresponds to the feed inlet of the rightmost discharge hopper II4. A magnetic plate I9 is ​​fixedly connected between the upper parts of the front and rear sides inside the housing 1. The magnetic plate I9 is ​​located inside the lower part of the upper conveyor assembly 8 and contacts the bottom area of ​​the conveyor belt of the upper conveyor assembly 8, so that the bottom of the upper conveyor assembly 8 is magnetic. A magnetic plate II91 is fixedly connected between the lower parts of the front and rear sides inside the housing 1. The magnetic plate II91 is located inside the lower conveyor assembly 8 and contacts the conveyor belt of the lower conveyor assembly 8. The left part of the lower conveyor assembly 8... For the non-magnetic area, two drive motors 92 are installed on the left side of the outer front side of the housing 1. The output shaft ends of the upper and lower drive motors 92 are respectively fixedly connected to the front end of the conveying roller on the left side of the upper and lower conveying components 8. The drive motors 92 are used to drive the conveying components 8 to rotate. The rotation of the conveying components 8 drives the metal waste to rotate through the magnetic plate I 9 and magnetic plate II 91, so that the metal waste is separated and collected. The material blocking component is installed between the housing 1 and the electric lifting frame 41. When the material blocking component is in operation, the material blocking component can intermittently block the waste.

[0032] Please see Figure 2 and Figure 3 As shown, the screening assembly includes a screen plate 5, a vibrating motor 6, connecting springs 7, and movable rods 71. Four movable rods 71 ​​are evenly spaced and slidably connected to the left and right sides of the electric lifting frame 41. The screen plate 5 is fixed between the bottom ends of the eight movable rods 71. The screen plate 5 is in an inclined state and is located inside the electric lifting frame 41. The screen plate 5 can screen the waste. The right side of the screen plate 5 corresponds to the feed inlet of the middle discharge hopper II 4. Three vibrating motors 6 are evenly spaced on the front and back sides of the bottom of the screen plate 5. Four connecting springs 7 are evenly spaced between the left and right sides of the screen plate 5 and the left and right sides of the electric lifting frame 41, respectively.

[0033] Please see Figure 6 and Figure 7 As shown, the material blocking assembly includes a baffle plate 10, an electromagnetic rod 101, a guide rod 1011, and a button 102. Three baffle plates 10 are vertically slidably connected at even intervals between the front and rear sides of the housing 1. The three baffle plates 10 slide through the screen plate 5, enabling intermittent blocking of waste. The baffle plates 10 have symmetrically arranged grooves on their front and rear sides. Three electromagnetic rods 101 are fixedly connected at even intervals on the front and rear sides of the electric lifting frame 41. The electromagnetic rods 101 correspond to the grooves of the baffle plates 10. The magnetic rod 101 can drive the blocking plate 10 to move upward. Buttons 102 are fixedly connected to both the front and rear sides of the housing 1. Buttons 102 are electrically connected to the electromagnetic rod 101. Buttons 102 and the blocking plate 10 are at the same level. Buttons 102 are located below the electric lifting frame 41. Three guide rods 1011 are fixedly connected to the front and rear sides of the housing 1 at even intervals. The three guide rods 1011 slide through the blocking plate 10. When the blocking plate 10 moves, the guide rods 1011 can guide the blocking plate 10.

[0034] First, the electric lifting frame 41 is activated to move up and down. This movement, via the connecting spring 7, causes the screen plate 5 to move up and down. As the screen plate 5 moves downwards, the upper part of the baffle plate 10 is positioned above it. Simultaneously, the electric lifting frame 41's movement also causes the electromagnetic rod 101 to move up and down. The electromagnetic rod 101 moves downwards and inserts into the groove of the baffle plate 10. At this point, the electric lifting frame 41 contacts the button 102. The button 102, through the control module, controls the electromagnetic rod 101 to activate for two seconds. The activation of the electromagnetic rod 101 attracts the baffle plate 10. Moving the electromagnetic rod 101 upwards then causes the baffle plate 10 to move upwards, synchronously with the upward movement of the screen plate 5. After two seconds, the electromagnetic rod 101 loses its magnetism, and the baffle plate 10 stops being attracted. When the electromagnetic rod 101 is attracted, the baffle plate 10 moves downwards to reset due to gravity. This process repeats, causing the baffle plate 10 to move up and down intermittently. Simultaneously, the vibration motor 6 is activated, vibrating the screen plate 5 via the connecting spring 7. Then, the upper drive motor 92 is activated to reverse, driving the upper conveying assembly 8 to reverse as well. At the same time, the lower drive motor 92 is activated to rotate forward, driving the lower conveying assembly 8 to rotate forward. This allows the waste to be discharged into the feed hopper 2. The waste in the feed hopper 2 falls into the housing 1 and contacts the screen plate 5. The screen plate 5 vibrates to screen the waste, and its up-and-down movement throws the waste up for further screening. Furthermore, under the action of the baffle plate 10, each time waste falls onto the screen plate 5... When the screen plate 10 is in operation, it can intermittently block the waste on the screen plate 5, allowing the waste to remain on the screen plate 5 for a longer period of time for screening, thus ensuring that the waste is fully screened. Under the action of the screen plate 5, small waste passes through the screen plate 5 and falls onto the lower conveyor component 8. The lower conveyor component 8 rotates forward, causing the small waste to rotate forward. At the same time, the magnetic plate II 91 attracts metal waste in the small waste onto the lower conveyor component 8. When the small waste rotates to the right, waste that is not metal falls into the leftmost discharge hopper II 4 and is discharged, while metal waste continues to be driven to rotate forward by the lower conveyor component 8. When the metal waste rotates to the left, it is in the non-magnetic area of ​​the lower conveyor component 8 and falls into the discharge hopper II 4. The waste is discharged and collected in hopper I3. At the same time, large waste is screened onto sieve plate 5, which throws the large waste upwards. The thrown large waste comes into contact with the upper conveying component 8. Magnetic plate II91 attracts the metal waste in the large waste to the upper conveying component 8, while waste that is not metal continues to fall onto sieve plate 5. Since sieve plate 5 is set at an incline, the large waste on sieve plate 5 falls into the middle discharge hopper II4 for collection. At the same time, the upper conveying component 8 reverses, causing the metal waste to reverse. When the metal waste reverses to the right and leaves the magnetic area, it falls into the rightmost discharge hopper II4 for collection. This process is repeated, which can continuously screen the waste by size and also screen the metal waste at the same time, thereby improving the screening effect.After all the waste has been screened, turn off the vibrating motor 6, the screen plate 5 stops vibrating, then turn off the electric lifting frame 41, the electric lifting frame 41 stops driving the screen plate 5 up and down through the connecting spring 7, and the electric lifting frame 41 also stops driving the electromagnetic rod 101 up and down. Then turn off the upper and lower drive motors 92, the upper conveying component 8 stops reversing and the lower conveying component 8 stops reversing, and small waste, large waste and metal waste can be processed later.

[0035] Please see Figure 8 and Figure 9 As shown, the large-scale waste screening and processing equipment also includes a cleaning component, which includes guide rods 11, n-shaped plates 111, brushes 112, and triggering components. Two guide rods 11 are fixedly connected to the upper inner side of both discharge hoppers I3 and II4. An n-shaped plate 111 is slidably fitted between the two guide rods 11 on each side. A brush 112 is fixedly connected to the top of the n-shaped plate 111. The left brush 112 contacts the lower conveying component 8, and the right brush 112 contacts the upper conveying component 8. When the brush 112 moves, it can remove the waste attached to the conveying component 8. Triggering components are installed on both discharge hoppers I3 and II4. When the triggering components operate, they can... The n-shaped plate 111 is now moved back and forth. The triggering component includes a rotating shaft 113, a drive cylinder 114, and a convex ball 115. The upper part of the discharge hopper I3 and the discharge hopper II4 are both rotatably connected to the rotating shaft 113. The front side of the right rotating shaft 113 is connected to the right side of the upper conveying component 8 through a synchronous belt assembly. The front side of the left rotating shaft 113 is connected to the left side of the lower conveying component 8 through a synchronous belt assembly. The drive cylinder 114 is symmetrically fixedly mounted on the left and right rotating shafts 113. The drive cylinder 114 has an inclined groove on its outer side. The drive cylinder 114 rotatably passes through the n-shaped plate 111. The convex ball 115 is fixedly connected to the inner side of the n-shaped plate 111. The convex ball 115 is located in the inclined groove of the drive cylinder 114.

[0036] When the upper conveyor assembly 8 rotates in reverse, the synchronous belt drives the right-side rotating shaft 113 to rotate. This rotation of the right-side rotating shaft 113 drives the right-side drive cylinder 114 to rotate, which in turn moves the right-side convex ball 115 back and forth. This movement of the right-side convex ball 115, in turn, moves the right-side n-shaped plate 111 back and forth, which in turn moves the right-side brush 112 back and forth, removing any debris adhering to the surface of the upper conveyor assembly 8. Similarly, when the lower conveyor assembly 8 rotates forward, the synchronous belt drives the left-side rotating shaft 113 to rotate, causing the left-side brush 112 to move back and forth, removing any debris adhering to the surface of the lower conveyor assembly 8. When both conveyor assemblies 8 stop rotating, the left and right brushes 112 stop moving. This prevents debris adhering to the surface of the conveyor assembly 8 from affecting the subsequent adsorption of metal waste, thus ensuring the effective use of the conveyor assembly 8.

[0037] Please see Figure 10 As shown, the large-scale waste screening and processing equipment also includes observation windows 12, which are symmetrically fixed and connected to the front side of the shell 1.

[0038] Please see Figure 10 As shown, the large-scale waste screening and processing equipment also includes a sealing baffle 13. The sealing baffle 13 is fixedly connected to the inner side of the shell 1. The sealing baffle 13 is located above the electric lifting frame 41. The sealing baffle 13 can block the gap between the screen plate 5 and the electric lifting frame 41.

[0039] When the waste is being screened, the operator can observe the screening process through the observation window 12. This allows for timely adjustments based on the screening status, ensuring proper screening of the waste.

[0040] When the screen plate 5 moves up and down to throw up the garbage for screening, the sealing baffle 13 can block the gap between the screen plate 5 and the electric lifting frame 41. In this way, the garbage can be prevented from falling into the gap between the screen plate 5 and the electric lifting frame 41 and affecting the vibration screening of the screen plate 5, thereby ensuring the normal vibration of the screen plate 5.

[0041] Finally, it is necessary to note that the above content is only used to help understand the technical solution of the present invention and should not be construed as a limitation on the scope of protection of the present invention; any non-essential improvements and adjustments made by those skilled in the art based on the above content of the present invention are all within the scope of protection claimed by the present invention.
