Description

Technical Field

[0001] The present invention relates to the technical field of solid waste treatment, and in particular to a historical solid waste recycling management system and method. Background Art

[0002] In the process of recycling and treating historical solid waste, crushers are often required to break the solid waste into appropriate sizes for subsequent processing and resource recovery. However, existing solid waste recycling management systems have some drawbacks, the most prominent of which is the inability to adjust the crushing and feeding speeds according to actual needs. This can easily cause solid waste to clog the crusher, affecting normal crushing operations.

[0003] When the solid waste is hard or irregular in shape, if the crushing speed is too fast or the feed rate is too fast, the solid waste will accumulate in the crusher and cannot be crushed in time, eventually clogging the crusher. When the solid waste is loose and fragile, if the crushing speed is too slow or the feed rate is too slow, the crushing efficiency will be affected, wasting time and energy.

[0004] In addition, traditional solid waste recycling and management systems usually lack real-time monitoring and feedback mechanisms for the crushing process. Operators find it difficult to accurately understand the working status of the crusher and the treatment of solid waste, and are unable to adjust the crushing speed and feed rate in time, further exacerbating the risk of blockage. Therefore, we propose a historical solid waste recycling and management system and method to solve this problem. Summary of the Invention

[0023] The present invention also provides a method for recycling and managing historical solid waste, which is applied to the above-mentioned historical solid waste recycling and management system, and includes the following steps:

[0024] S1. Put the solid waste into the feed frame and start the crushing motor and the drive motor. The crushing motor drives the horizontal shaft and the two active bevel gears to rotate. The active bevel gears engage with the corresponding driven bevel gears to drive the two crushing rollers to rotate in the opposite direction, thus achieving the first-level crushing of the solid waste.

[0025] S2. The solid waste after primary crushing falls through the feeding gap between the feed hopper and the baffle plate, and the drive motor drives the conical plate and the drive shaft to rotate, and the drive shaft drives the crushing knife to rotate, thus achieving secondary crushing of the solid waste;

[0026] S3. The driving shaft drives the rotating column to rotate, and drives the abutment wheel to perform circular motion. The abutment wheel pushes the screen upward by abutting with the arc-shaped protrusion. After the abutment wheel is out of contact with the arc-shaped protrusion, the screen is reset downward under the action of gravity, thereby driving the connecting ring to move up and down. The connecting ring can rotate while moving up and down through the cooperation of the oblique protrusion and the inclined slot, thereby driving the screen to shake up and down and reciprocate, thereby realizing the screening of solid waste and making the solid waste evenly distributed on the screen, so that the solid waste with unqualified crushed particle size shakes up and down on the screen, and is continuously rolled by the rotation of the crushing knife. The solid waste crushed to a qualified particle size falls through the screen and falls onto the conical disk through the discharge port. The conical disk throws the crushed material outward while rotating, and under the guidance of the discharge port, the solid waste is directionally discharged through the discharge hopper;

[0027] S4. The downward pressure exerted on the mounting base is monitored by a pressure sensor, so that the amount of solid waste in the casing can be analyzed. When the pressure sensor detects an increase in pressure, the controller controls the speed of the driving motor to increase and the speed of the crushing motor to decrease, thereby driving the driving shaft and the crushing knife to rotate faster, improving the crushing effect, and at the same time increasing the frequency of the up and down movement of the screen to increase the screening rate. At the same time, when the speed of the driving shaft increases, the speed of the vertical plate's circular motion increases, so that the vertical plate is thrown outward under the action of centrifugal force and the degree of compression of the compression spring is increased. At the same time, the vertical plate drives the baffle plate to move upward through cooperation with the corresponding inclined rod, thereby reducing the gap between the baffle plate and the feed hopper to reduce the feeding rate and avoid excessive accumulation of solid waste on the screen and blockage. At the same time, the speed reduction of the crushing motor can reduce the speed of the two crushing rollers, thereby reducing the crushing rate of the primary crushing mechanism and slowing down the crushing pressure of the secondary crushing mechanism.

[0028] S5. Pull the handle backward to drive the U-shaped seat to move backward, so that the U-shaped seat is out of contact with the side plate, thereby releasing the fixation of the crushing box, and the crushing box can be moved upward to be disassembled for easy cleaning.

[0029] The beneficial effects of the present invention are:

[0030] 1. In the present invention, a historical solid waste recycling management system and method is described, wherein solid waste is placed in a feed frame and a crushing motor and a drive motor are started. The crushing motor drives the horizontal shaft and two active bevel gears to rotate. The active bevel gears drive two crushing rollers to rotate in opposite directions by meshing with corresponding driven bevel gears, thereby achieving primary crushing of the solid waste. The solid waste after primary crushing falls through the feed gap between the feed hopper and the baffle plate, and the conical plate and the drive shaft are driven by the drive motor to rotate. The drive shaft drives the crushing cutter to rotate, thereby achieving secondary crushing of the solid waste.

[0031] The sieve is then driven by the rollers to move in a circular motion, and the rollers are driven to move in a circular motion, and the rollers are driven to push the sieve upwards, and after the rollers are out of contact with the rollers, the sieve is reset downwards under the action of gravity, thereby driving the connecting ring to move up and down. The connecting ring can rotate while moving up and down through the cooperation of the oblique protrusions and the inclined slots, thereby driving the sieve to shake up and down and rotate back and forth, thereby screening the solid waste and making the solid waste evenly distributed on the sieve. The solid waste with unqualified particle size is shaken up and down on the sieve, and is continuously rolled by the rotation of the crushing knife. The solid waste crushed to a qualified particle size falls through the sieve and falls onto the conical disk through the discharge port. The conical disk throws the crushed material outwards while rotating, and under the guidance of the discharge port, the solid waste is discharged directionally through the discharge hopper.

[0032] 3. In the present invention, a historical solid waste recycling management system and method is described, which monitors the downward pressure on the mounting seat through a pressure sensor, thereby analyzing the amount of solid waste in the casing; when the pressure sensor detects an increase in pressure, the controller controls the speed of the drive motor to increase and the speed of the crushing motor to decrease, thereby driving the drive shaft and the crushing knife to rotate faster, improving the crushing effect, and at the same time increasing the up and down movement frequency of the screen to increase the screening rate; at the same time, when the speed of the drive shaft increases, the speed of the vertical plate in circular motion increases, so that the vertical plate is thrown outward under the action of centrifugal force and the degree of compression of the compression spring is increased; at the same time, the vertical plate drives the baffle plate to move upward through cooperation with the corresponding inclined rod, thereby reducing the gap between the baffle plate and the feed hopper to reduce the feeding rate and avoid excessive accumulation of solid waste on the screen and blockage; at the same time, the speed reduction of the crushing motor can reduce the speed of the two crushing rollers, thereby reducing the crushing rate of the primary crushing mechanism, thereby slowing down the crushing pressure of the secondary crushing mechanism;

[0033] 4. In the present invention, the historical solid waste recycling management system and method is described, by pulling the handle backward to drive the U-shaped seat to move backward, so that the U-shaped seat is out of contact with the side plate, thereby releasing the fixation of the crushing box, and the crushing box can be moved upward, thereby being disassembled for easy cleaning;

[0034] 5. In the present invention, the historical solid waste recycling management system and method can conveniently realize double crushing and screening of solid waste by setting a primary crushing mechanism, a secondary crushing mechanism and a screen, thereby ensuring the crushing quality. In conjunction with the pressure sensor and the feeding mechanism, the intelligent adjustment of the feeding rate can be realized, thereby maintaining a reasonable material inventory, avoiding blockage caused by material stockpiling, and ensuring the continuous and stable progress of the crushing work.

The discharge barrel 8 is movably abutted against the outer side of the conical disk 502, and a notch is provided on one side of the discharge barrel 8. A discharge hopper 9 is provided on one side of the notch to facilitate discharge.

[0062] In this embodiment, a crushing motor 206 and two mounting plates 205 are fixedly mounted on the top of the casing 1. A horizontal shaft 204 is fixedly mounted on the output shaft of the crushing motor 206. The horizontal shaft 204 is rotatably mounted in the two mounting plates 205. Two driving bevel gears 203 are fixedly mounted on the horizontal shaft 204. A driven bevel gear 202 is fixedly mounted on the front end of the crushing roller 201. The two driving bevel gears 203 are respectively engaged with different sides of the corresponding driven bevel gears 202, so that the same-direction rotation of the two driving bevel gears 203 can drive the two driven bevel gears 202 to rotate in opposite directions.

[0063] The crushing motor 206 is connected to the controller 10 via a signal. When the pressure sensor 402 detects that the pressure increases, the controller 10 controls the speed of the driving motor 406 to increase and the speed of the crushing motor 206 to decrease.

[0064] In this embodiment, a plurality of supporting legs 102 are fixedly mounted on the outer bottom of the casing 1, two slide rails 301 are fixedly mounted on the top rear side of the casing 1, and the outer sides of the two slide rails 301 are slidably sleeved with the same U-shaped seat 3, a positioning spring 302 is fixedly mounted on the rear side of the U-shaped seat 3, and a baffle is fixedly mounted on the other end of the positioning spring 302, and the baffle is fixedly mounted on the top of the casing 1, and a handle 303 is fixedly mounted on the top of the U-shaped seat 3, so as to facilitate manual pulling of the U-shaped seat 3 for movement;

[0065] A square hole is provided on the top of the casing 1, and the crushing box 2 is movably inserted into the square hole. Side panels 207 are fixedly installed on both sides of the crushing box 2, and the side panels 207 are movably abutted against the top of the casing 1. The U-shaped seat 3 is movably abutted against the top of the two side panels 207. A feeding frame 208 is fixedly installed on the top of the crushing box 2 to facilitate feeding into the crushing box 2.

[0066] In this embodiment, when in use, by putting solid waste into the feed frame 208, and starting the crushing motor 206 and the driving motor 406, the crushing motor 206 drives the horizontal shaft 204 and the two active bevel gears 203 to rotate, and the active bevel gear 203 drives the two crushing rollers 201 to rotate in the opposite direction by meshing with the corresponding driven bevel gear 202, thereby achieving the first-level crushing of the solid waste. The solid waste after the first-level crushing falls through the feeding gap between the feed hopper 101 and the baffle 6, and is driven by the driving motor 406 to rotate the conical disk 502 and the driving shaft 5, and the driving shaft 5 drives the crushing knife 501 to rotate, thereby achieving the second-level crushing of the solid waste. The driving shaft 5 drives the rotating column 503 to rotate, and drives the abutment wheel 504 to move in a circular motion. The abutting wheel 504 pushes the screen 7 to move upward by abutting against the arc-shaped protrusion 702. After the abutting wheel 504 is out of contact with the arc-shaped protrusion 702, the screen 7 is reset downward under the action of gravity, thereby driving the connecting ring 703 to move up and down. The connecting ring 703 can rotate while moving up and down through the cooperation of the oblique protrusion and the inclined groove 104, thereby driving the screen 7 to shake up and down and reciprocate, thereby realizing the screening of solid waste and making the solid waste evenly distributed on the screen 7, so that the solid waste with unqualified particle size is shaken up and down on the screen 7, and is continuously rolled by the rotation of the crushing knife 501, and the solid waste crushed to a qualified particle size falls through the screen 7 and falls onto the conical disk 502 through the discharge port. The conical disk 502 throws the crushed material outward while rotating, and under the guidance of the discharge port, the solid waste is discharged in a direction through the discharge hopper 9. The downward pressure on the mounting base 401 is monitored by the pressure sensor 402, so that the solid waste inventory in the casing 1 can be analyzed. When the pressure sensor 402 detects an increase in pressure, the controller 10 controls the speed of the drive motor 406 to increase and the speed of the crushing motor 206 to decrease, thereby driving the drive shaft 5 and the crushing knife 501 to rotate faster, improving the crushing effect, and at the same time increasing the up and down movement frequency of the screen 7 to increase the screening rate. At the same time, when the speed of the drive shaft 5 increases, the speed of the circular motion of the vertical plate 602 will increase, so that the vertical plate 602 will move under the action of centrifugal force. The vertical plate 602 is driven by the cooperation with the corresponding inclined rod 601 to drive the baffle plate 6 to move upward, thereby reducing the gap between the baffle plate 6 and the feed hopper 101 to reduce the feeding rate and avoid excessive accumulation of solid waste on the screen 7 and blockage. At the same time, the speed of the crushing motor 206 is reduced, which can reduce the speed of the two crushing rollers 201, thereby reducing the crushing rate of the first-level crushing mechanism and slowing down the crushing pressure of the second-level crushing mechanism. The U-shaped seat 3 is driven to move backward by pulling the handle 303 backward, so that the U-shaped seat 3 is out of contact with the side plate 207, thereby releasing the fixation of the crushing box 2, so that the crushing box 2 can be moved upward and disassembled for easy cleaning.

[0067] The present invention also provides a method for recycling and managing historical solid waste, which is applied to the above-mentioned historical solid waste recycling and management system, and comprises the following steps:

[0068] S1. Put the solid waste into the feeding frame 208 and start the crushing motor 206 and the driving motor 406. The crushing motor 206 drives the horizontal shaft 204 and the two active bevel gears 203 to rotate. The active bevel gears 203 drive the two crushing rollers 201 to rotate in the opposite direction by meshing with the corresponding driven bevel gears 202, thereby achieving the first-level crushing of the solid waste.

[0069] S2. The solid waste after primary crushing falls through the feed gap between the feed hopper 101 and the baffle 6, and the drive motor 406 drives the conical disk 502 and the drive shaft 5 to rotate, and the drive shaft 5 drives the crushing blade 501 to rotate, thereby achieving secondary crushing of the solid waste;

[0070] S3. The driving shaft 5 drives the rotating column 503 to rotate and drives the abutting wheel 504 to perform circular motion. The abutting wheel 504 pushes the screen 7 to move upward by abutting against the arc-shaped protrusion 702. After the abutting wheel 504 is out of contact with the arc-shaped protrusion 702, the screen 7 is reset downward under the action of gravity, thereby driving the connecting ring 703 to move up and down. The connecting ring 703 can rotate while moving up and down through the cooperation of the oblique protrusion and the inclined groove 104, thereby driving the screen 7 to shake up and down and reciprocate. Rotation achieves screening of solid waste and makes the solid waste evenly distributed on the screen 7, so that the solid waste with unqualified particle size shakes up and down on the screen 7 and is continuously rolled by the rotation of the crushing knife 501. The solid waste with qualified particle size falls through the screen 7 and falls onto the conical disk 502 through the discharge port. The conical disk 502 throws the crushed material outward while rotating, and under the guidance of the discharge port, the solid waste is discharged in a direction through the discharge hopper 9;

[0071] S4. The downward pressure on the mounting base 401 is monitored by the pressure sensor 402, so as to analyze the amount of solid waste in the casing 1. When the pressure sensor 402 detects an increase in pressure, the controller 10 controls the speed of the drive motor 406 to increase and the speed of the crushing motor 206 to decrease, thereby driving the drive shaft 5 and the crushing knife 501 to rotate faster, improving the crushing effect, and at the same time increasing the up and down movement frequency of the screen 7 to increase the screening rate. At the same time, when the speed of the drive shaft 5 increases, the speed of the circular motion of the vertical plate 602 will increase. The vertical plate 602 is thrown outward under the action of centrifugal force, and the degree of compression of the compression spring 604 is increased. At the same time, the vertical plate 602 drives the baffle plate 6 to move upward by cooperating with the corresponding inclined rod 601, thereby reducing the gap between the baffle plate 6 and the feed hopper 101, thereby reducing the feeding rate and preventing excessive accumulation of solid waste on the screen 7 and causing blockage. At the same time, the speed reduction of the crushing motor 206 can reduce the speed of the two crushing rollers 201, thereby reducing the crushing rate of the primary crushing mechanism and thus easing the crushing pressure of the secondary crushing mechanism.

[0072] S5. Pull the handle 303 backward to drive the U-shaped seat 3 to move backward, so that the U-shaped seat 3 is out of contact with the side plate 207, thereby releasing the fixation of the crushing box 2, and the crushing box 2 can be moved upward to be disassembled for easy cleaning.

The U-shaped seat (3) is movably abutted against the tops of the two side panels (207). A feed frame (208) is fixedly installed on the top of the crushing box (2).

7. A method for recycling and managing historical solid waste, applied to the historical solid waste recycling and management system according to claim 6, characterized in that: The steps include: S1. Solid waste is placed in a feeding frame (208), and a crushing motor (206) and a driving motor (406) are started. The crushing motor (206) drives the horizontal shaft (204) and two driving bevel gears (203) to rotate. The driving bevel gears (203) drive the two crushing rollers (201) to rotate in opposite directions by meshing with the corresponding driven bevel gears (202), thereby achieving primary crushing of the solid waste. S2, the solid waste that has undergone primary crushing falls through the feed gap between the feed hopper (101) and the baffle (6), and the drive motor (406) drives the conical disk (502) and the drive shaft (5) to rotate, and the drive shaft (5) drives the crushing blade (501) to rotate, thereby achieving secondary crushing of the solid waste; S3. The driving shaft (5) drives the rotating column (503) to rotate and drives the contact wheel (504) to perform circular motion. The contact wheel (504) pushes the screen (7) to move upward by contacting with the arc-shaped protrusion (702). After the contact wheel (504) is out of contact with the arc-shaped protrusion (702), the screen (7) is reset downward under the action of gravity, thereby driving the connecting ring (703) to move up and down. The connecting ring (703) can rotate while moving up and down through the cooperation of the oblique protrusion and the inclined groove (104), thereby driving the screen (7) to move upward. The crushing knife (501) rotates downward and reciprocatingly, thereby screening the solid waste and making the solid waste evenly distributed on the screen (7). The solid waste with unqualified particle size is shaken up and down on the screen (7) and continuously rolled by the rotation of the crushing knife (501). The solid waste crushed to a qualified particle size falls through the screen (7) and falls onto the conical disk (502) through the discharge port. The conical disk (502) throws the crushed material outward while rotating, and under the guidance of the discharge port, the solid waste is discharged directionally through the discharge hopper (9); S4. The downward pressure on the mounting base (401) is monitored by the pressure sensor (402), so that the amount of solid waste in the housing (1) can be analyzed. When the pressure sensor (402) detects an increase in pressure, the controller (10) controls the speed of the driving motor (406) to increase, and controls the speed of the crushing motor (206) to decrease, thereby driving the driving shaft (5) and the crushing knife (501) to rotate faster, improving the crushing effect, and at the same time increasing the frequency of the upward and downward movement of the screen (7) to increase the screening rate. At the same time, when the speed of the driving shaft (5) increases, the speed of the circular motion of the vertical plate (602) will increase. The degree of rotation increases, causing the vertical plate (602) to be thrown outward under the action of centrifugal force, and increasing the degree of compression of the compression spring (604). At the same time, the vertical plate (602) drives the baffle plate (6) to move upward through cooperation with the corresponding inclined rod (601), thereby reducing the gap between the baffle plate (6) and the feed hopper (101), thereby reducing the feeding rate and preventing excessive accumulation of solid waste on the screen (7) and causing blockage. At the same time, the speed of the crushing motor (206) is reduced, which can reduce the speed of the two crushing rollers (201), thereby reducing the crushing rate of the primary crushing mechanism and thus reducing the crushing pressure of the secondary crushing mechanism. S5. Pulling the handle (303) backward drives the U-shaped seat (3) to move backward, so that the U-shaped seat (3) is out of contact with the side plate (207), thereby releasing the fixation of the crushing box (2), and the crushing box (2) can be moved upward, thereby being disassembled for easy cleaning.
