Description

Technical Field

[0001] This invention relates to the field of solid waste treatment technology, and more specifically, to an industrial solid waste treatment device. Background Technology

[0002] In existing technologies, the treatment of industrial solid waste typically employs mechanical crushing for initial volume reduction. Crushers, as the most common crushing equipment, are widely used in various solid waste treatment production lines. However, traditional crushers commonly suffer from rotor jamming and clogging during actual operation, affecting the continuity and efficiency of solid waste treatment. Specifically, the composition of industrial solid waste is extremely complex and diverse, including high-hardness, high-strength solid materials such as metal scraps, ceramic fragments, and concrete blocks, as well as flexible materials with greater toughness such as plastic products, rubber waste, and textile scraps. It also contains various impurities such as dust, sand, and soil. These wastes of different properties typically do not undergo rigorous sorting and pretreatment before entering the crushing chamber of the crusher. In practice, when large or extremely hard lumps enter the crushing chamber along with other materials, these large lumps often exceed the pre-set crushing gap between the crusher rotor and the crushing chamber wall, or their material strength exceeds the ultimate crushing force that the rotor's crushing teeth can withstand. These difficult-to-crush lumps will be clamped between the rotor teeth under the high-speed rotation of the rotor. As the rotor continues to rotate and subsequent materials accumulate, the stuck lumps will exert huge radial and tangential resistance on the rotor, increasing the rotor's rotational resistance torque, causing the rotational speed to drop rapidly or even stop completely, affecting the subsequent crushing effect. Moreover, during the cleaning process, operators need to directly contact the sharp waste that has not been completely crushed, posing safety hazards such as scratches and injuries.

[0003] Another issue closely related to rotor jamming is the rotor sticking and jamming phenomenon in crushers, leading to motor overload failures. Traditional crusher rotors typically employ multiple rows of staggered crushing teeth or hammers. Numerous gaps and grooves exist between these crushing elements and between the crushing elements and the rotor body. When hard objects cause jamming, the rotor's load torque increases significantly. To maintain the predetermined speed and processing capacity, the drive motor must output greater power and torque to overcome the increased load resistance. The motor's actual operating current gradually rises above the rated current, entering an overload operating state. Prolonged overload operation causes the motor winding temperature to continuously rise, exceeding the allowable operating temperature of the insulation material. Overloading accelerates the thermal aging, embrittlement, and even carbonization of the insulation layer. Simultaneously, motor overload reduces the motor's power factor and efficiency, increasing energy consumption and operating costs. More seriously, if operators fail to detect motor overload signs in time and take measures such as reducing feed rate or stopping the machine for cleaning, the motor will continue to operate under overload conditions until the thermal protection device activates or the motor windings burn out. Once the motor is damaged, the entire solid waste treatment production line must be shut down for motor disassembly, repair, or replacement, causing huge economic losses and environmental pressure. Furthermore, the repeated occurrence of rotor jamming and motor overload problems forces workers to adopt overly conservative operating strategies such as reducing feed rate and frequent machine shutdowns for inspection, further sacrificing the equipment's processing capacity and production efficiency.

The limiting strips are embedded in the limiting grooves and slidably connected with the limiting grooves.

[0015] (III) Beneficial Effects Compared with existing technologies, this invention provides an industrial solid waste treatment device with the following advantages: This invention constructs an active foreign object discharge mechanism by setting an eccentric ring structure between adjacent rotors, solving the problem of equipment blockage caused by large hard objects getting stuck in the rotor gap. Specifically, the eccentric ring is installed in the gap between the rotors of the drive shaft and the follower shaft, and its inner wall has a groove that meshes with the teeth on the outer wall of the fixed ring. This meshing relationship ensures that the eccentric ring can rotate synchronously with the rotation of the drive shaft or the follower shaft. Simultaneously, the inner side of the eccentric ring... The wall is slidably connected to the first and second fixed rods that penetrate the inner cavity of the crusher through a slot. The constraint effect of the fixed rods restricts the eccentric ring to only rotate around the axis of the drive shaft or follower shaft without causing radial movement. This motion constraint mechanism ensures that the eccentric ring always maintains a stable rotation trajectory. When large hard objects such as metal blocks, ceramic fragments, and concrete blocks mixed in with industrial solid waste enter the crushing chamber of the crusher along with other materials, these hard objects cannot be immediately crushed by the crushing teeth of the rotor due to their large size or excessive hardness. The high-speed rotation of the rotor generates... Under the influence of centrifugal force and material flow dynamics, these large hard objects are easily squeezed into the gap space between two adjacent sets of rotors. Once the hard object is wedged into the rotor gap, it will be driven to rotate with the rotation of the rotor. In traditional crushers, because there is no auxiliary discharge device in the rotor gap, these stuck hard objects will be clamped between the rotors until the rotors are completely jammed or forcibly crushed through repeated collisions. However, in this invention, when a large hard object is stuck in the rotor gap and rotates to the lowest position with the rotor, the hard object will naturally sink due to gravity and collide with the outer wall of the eccentric ring located in the rotor gap. When a contact collision occurs, the eccentric ring is in the rising phase of its rotation cycle, where the radius of its outer wall gradually increases. The arc-shaped surface of the outer wall of the eccentric ring will exert a downward and outward squeezing force on the hard object that is stuck in it. The direction of this squeezing force is consistent with the direction in which the hard object is released from the rotor gap. As the eccentric ring continues to rotate, when its outer wall radius reaches its maximum value, the squeezing force on the hard object also reaches its peak value. Under the action of this maximum squeezing force, the large hard object will be forcibly pushed out of the rotor gap and fall downward to the bottom of the crusher, thereby avoiding the problem of jamming and blockage caused by the hard object remaining in the rotor gap for a long time.

[0016] This invention designs an overload protection mechanism based on hydraulic buffering and relative rotation principles. This mechanism, through hydraulic oil flow regulation and mechanical sliding cooperation, constructs a flexible power transmission system capable of responding to sudden load changes, eliminating the risk of motor burnout due to rotor jamming. The core working principle of the overload protection mechanism is to insert a buffer transmission device consisting of a connecting plate, connecting cylinder, turntable, and hydraulic chamber system between the reducer output end and the drive shaft. Under normal operating conditions, the reducer output end drives the connecting plate to rotate, and the connecting plate drives the connecting cylinder to rotate synchronously through multiple sets of connecting rods. The turntable inside the connecting cylinder is fixedly connected to the drive shaft and rotates together with the drive shaft. Because there is a possibility of relative rotation between the connecting cylinder and the turntable, when the rotor inside the crusher runs smoothly, the connecting cylinder and the turntable rotate synchronously. The entire overload protection mechanism transmits torque as a rigid whole. However, once the rotor gets stuck inside the crusher and the rotation of the drive shaft is obstructed or even stops completely, the output end of the reducer will continue to drive the connecting cylinder to rotate. At this time, relative rotation will occur between the connecting cylinder and the turntable. This relative rotation will trigger the directional flow and pressure redistribution of the hydraulic oil in the hydraulic chamber system, ultimately achieving a temporary interruption of power transmission or a flexible buffer of torque, avoiding the direct action of all the torque output by the motor on the stuck rotor, which would cause the motor to stall and overload.

[0017] The hydraulic overload protection system has multiple sets of circumferentially evenly distributed first and fourth hydraulic chambers inside the turntable. A push rod is slidably installed in each first hydraulic chamber. A sliding ball connected to the end of the push rod abuts against a groove on the inner wall of the connecting cylinder. The groove wall has an undulating, wave-like shape. When the connecting cylinder rotates relative to the turntable, the groove wall pushes the sliding ball and push rod to slide back and forth within the first hydraulic chamber. The sliding of the push rod compresses the hydraulic oil in the first hydraulic chamber, increasing its pressure. The high-pressure hydraulic oil flows outward along an inner pipe that is connected to the first hydraulic chamber. The other end of the inner pipe connects to a second hydraulic chamber inside a telescopic sleeve installed within the outer pipe. When the hydraulic oil enters the second hydraulic chamber, it exerts a thrust on the pressure plate inside the second hydraulic chamber. The back of the pressure plate is supported by a compression spring. Under normal small load fluctuations, the hydraulic oil pressure is insufficient to overcome the preload of the compression spring, and the pressure plate remains stationary, continuing to block the connection between the second and third hydraulic chambers. At this time, the hydraulic oil cannot continue to flow and the hydraulic system is in a locked state. Only a small relative rotation can occur between the connecting cylinder and the turntable, which plays an elastic buffering role. This small relative rotation can absorb the periodic load pulsation generated during normal operation of the crusher, making the power transmission process smoother and reducing impact vibration.

[0018] However, when severe jamming occurs inside the crusher, the output of the reducer continuously drives the connecting cylinder to rotate, causing the relative angle between the connecting cylinder and the turntable to increase continuously. The pushing stroke of the slide rail on the sliding ball and push rod also increases accordingly, causing a sharp rise in hydraulic oil pressure in the first hydraulic chamber. When the pressure reaches a critical value that can overcome the preload of the compression spring, the high-pressure hydraulic oil pushes the pressure plate backward to compress the compression spring. The movement of the pressure plate releases the seal between the second and third hydraulic chambers, allowing hydraulic oil to flow from the second hydraulic chamber into multiple sets of third hydraulic chambers. The third hydraulic chamber connects with the annular cavity formed between the outer and inner pipes. The hydraulic oil continues to flow along the annular cavity and eventually enters the fourth hydraulic chamber. The chamber is also equipped with a push rod and a slider. The flowing hydraulic oil pushes the push rod in the fourth hydraulic chamber, causing the slider at its end to extend outward along the slide groove. Because the slider in the first hydraulic chamber is pushed into the chamber by the slide groove due to the rotation of the connecting cylinder, it compresses the hydraulic oil. Meanwhile, the slider in the fourth hydraulic chamber extends outward along the slide groove under the push of the hydraulic oil, increasing the contact force with the slide groove. This change in the position of the slider generates a torque that drives the turntable to rotate relative to the connecting cylinder. Under the action of this hydraulic driving torque, the turntable will drive the drive shaft to rotate slightly in the opposite or same direction to compensate. This compensation rotation releases the torsional stress accumulated due to jamming, avoids the transmission system from bearing excessive torque impact, and achieves the purpose of overload protection.

[0026] In this invention, when treating industrial solid waste, the motor 11 is first started, driving the drive wheel 12 to rotate. This, in turn, drives the follower wheel 15 via the belt 16, which in turn drives the reducer 14. The output of the reducer 14 drives the drive shaft 22 to rotate via an overload protection mechanism. Then, the drive gear 25 drives the follower gear 26, which meshes with it, to rotate synchronously with the follower shaft 23. The drive shaft 22 and the follower shaft 23 rotate in opposite directions, ultimately driving multiple sets of rotors 24 to rotate, conveying the waste material into the crusher 21. The multiple sets of rotors 24 crush the incoming waste material. The rotation of the drive shaft 22 and the follower shaft 23 causes the fixing ring 211 fitted on their surfaces to rotate accordingly. 1. The first fixing rod 29 and the second fixing rod 210 determine the position of the eccentric ring 27. Because the groove 28 on the inner side wall of the eccentric ring 27 meshes with the tooth 212 on the outer side wall of the fixing ring 211, the rotation of the fixing ring 211 drives the eccentric ring 27 to rotate synchronously. When the rotor 24 encounters large pieces of hard waste during the crushing process and gets stuck in the gap between the rotors 24, the large pieces of waste rotate with the rotor 24 until the large pieces of waste rotate to the lowest point. At this time, the large pieces of waste will collide with the outer side wall of the eccentric ring 27 set between the rotors 24. Under the action of the eccentric ring 27, the large pieces of waste will be squeezed out. This mechanism can effectively prevent hard objects from getting stuck in the gap between the rotors 24. When the rotor 24 inside the crusher 21 becomes stuck, the load on the motor 11 increases. At this time, the overload protection mechanism is activated. Under normal operating conditions, the overload protection mechanism rotates as a whole with the drive shaft 22, and there is no relative rotation inside. However, when a stuck situation occurs, the output end of the reducer 14 still drives the connecting plate 31 to rotate. The connecting plate 31 drives the connecting rod 32 and the connecting cylinder 33 to rotate synchronously. However, the turntable 34 will rotate relative to the connecting cylinder 33 inside the connecting cylinder 33. The first hydraulic chamber 38, the second hydraulic chamber 317, the third hydraulic chamber 318, the fourth hydraulic chamber 39, the inner tube 35, and the cavity between the outer tube 36 and the inner tube 35 are all filled with hydraulic oil. The push rod 310 in each group of the first hydraulic chamber 38 is located at the lowest point of the slide 37, and the push rod 310 in each group of the fourth hydraulic chamber 39 is located at the highest point of the slide 37. When the crusher 21 is stuck, the turntable 34 also becomes stuck, but the connecting cylinder 33 continues to rotate. At this time, the first hydraulic chamber 38... Hydraulic oil in cavity 38 is pressurized and flows into inner tube 35, then continues to flow into second hydraulic cavity 317 through inner tube 35. The pressure in second hydraulic cavity 317 increases until it overcomes the thrust of spring 315 and pushes pressure plate 316 backward, releasing the seal between pressure plate 316 and second hydraulic cavity 317 and third hydraulic cavity 318. At this time, hydraulic oil flows into multiple sets of third hydraulic cavities 318, and then continues to flow into the cavity between outer tube 36 and inner tube 35 through third hydraulic cavity 318, finally flowing into fourth hydraulic cavity 39 to press push rod 310 in fourth hydraulic cavity 39. At this time, each set of sliding rods and sliding balls 311 start to rotate along the side wall of sliding groove 37 as the hydraulic oil in the corresponding hydraulic cavity increases or decreases, thereby driving turntable 34 and connecting cylinder 33 to rotate relative to each other, achieving the purpose of overload prevention. The pressure provided by spring 315 to pressure plate 316 can be adjusted by adjusting threaded rod 314, thereby adjusting the force required for hydraulic oil to push pressure plate 316 open.
