Description

Technical Field

[0001] The present invention relates to the technical field related to solid waste treatment, and in particular to an anti-jamming mechanism for solid waste treatment equipment. Background Art

[0002] As we all know, solid waste refers to solid, semi-solid and gaseous items and substances produced in production, life and other activities that have lost their original utilization value or have not lost their utilization value but have been discarded or abandoned, as well as items and substances that are included in solid waste management as stipulated by laws and administrative regulations. Solid waste treatment is an important part of environmental protection and sustainable development.

[0003] For the recycling and reuse of some solid wastes, it is necessary to shred them, that is, to use a shredder to shred the solid waste into smaller volumes for subsequent recycling and reprocessing. For example, the patent with the announcement number CN118543400A and the announcement date of August 27, 2024, entitled "A double-shaft shredder for solid waste treatment and its use method", belongs to the field of pulverization equipment technology. The device includes a pulverization device, a driving device and a control device, wherein the pulverization device includes a pulverization box, in which a first pulverization roller and a second pulverization roller are rotatably installed. The crushing roller and the driving device are connected to the first crushing roller. When in use, under the action of the driving device, the first crushing roller and the second crushing roller rotate synchronously in opposite directions, and the solid waste to be crushed falls between the first crushing roller and the second crushing roller and is quickly shredded. When a certain solid waste is stuck between the first crushing roller and the second crushing roller and cannot be shredded normally, the first crushing roller and the second crushing roller rotate synchronously in opposite directions, and the solid waste that cannot be shredded can be quickly transferred out from between the first crushing roller and the second crushing roller, making it easy for the user to take it away, thereby quickly restoring the crushing device to a normal working state and being easy to use.

[0004] Among them, the shredder may have a problem of material jamming during the process of shredding solid waste. In the prior art, the jamming problem is solved by reversing the two shredding rollers of the shredder to spit out the solid waste in the reverse direction. However, if the solid waste is stuck between two axially adjacent shredding teeth of the shredding roller, it will be difficult to spit it out by reversing the shredding roller, and it will also cause the two shredding rollers to get stuck after reversing, which requires human intervention, which undoubtedly has an adverse effect on the solid waste processing efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a material-jamming prevention mechanism for solid waste treatment equipment to solve the technical problems in related technologies.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A material jam prevention mechanism for solid waste treatment equipment includes a frame and a shredder box arranged on the frame, wherein two shredder rollers are arranged side by side in the shredder box, and the two shredder rollers rotate relative to each other under the drive of a driving mechanism. The invention also includes an anti-jamming component, which includes two base plates arranged in the shredder box, and each base plate is sequentially installed with multiple guide plates along the axial direction of the shredder roller. During the rotation of the shredder roller, the multiple guide plates guide solid waste stuck on the shredder roller away from the shredder roller.

[0008] As mentioned above, in the direction of feeding the shredded solid waste, both the upper and lower sides of the guide plate are inclined.

[0009] As mentioned above, a ring body is installed between two shredding teeth at adjacent positions on the shredding roller, and a plurality of movable blocks are arranged to swing in sequence in the circumferential direction of the ring body, and a first elastic member is also connected between each movable block and the ring body; along the circumference of the ring body, both ends of the movable block are convex structures, and when the convex part at one end of the ring body is squeezed by external force and swings toward the inside of the ring body, the convex part at the other end swings toward the outside of the ring body.

[0010] As mentioned above, in the direction of material discharge, a first push rod is swingably provided on the upper side of the guide plate, and a second elastic member is also provided between the first push rod and the guide plate; during the rotation of the shredding roller to shred the solid waste, the first push rod jumps on the guide plate based on the pushing action of each movable block.

[0011] As mentioned above, in the direction of material discharge, a second push rod is swingably provided on the lower side of the guide plate, and a third elastic member is also provided between the second push rod and the guide plate; during the rotation of the shredding roller to spit out solid waste, the second push rod jumps on the guide plate based on the pushing action of each movable block.

[0012] As mentioned above, a first notch is provided on a raised portion of the movable block. During the process of the shredding roller rotating to spit out solid waste, the first push rod is first plugged into each first notch in turn and then separated. During the process of the first push rod being plugged into any first notch, the first push rod pushes the end of the movable block corresponding to the first notch to move in a direction deviating from the ring body.

[0013] As mentioned above, a second notch is provided on another raised portion of the movable block. During the travel of the shredding roller to shred the solid waste, the second push rod is first plugged into each second notch in turn and then separated; during the travel of the second push rod being plugged into any second notch, the second push rod pushes the end of the movable block corresponding to the second notch to move in a direction deviating from the ring body.

[0014] As mentioned above, a transmission rod is connected between two adjacent movable blocks. When any movable block performs a swinging action, the movable block at the adjacent position swings based on the transmission action of the transmission rod.

[0015] As mentioned above, the transmission rod is composed of two sections that are slidably connected to each other, and during the plug-in stroke of the first push rod and the first notch, the swing path length of the movable block is greater than the elongation of the transmission rod, and during the plug-in stroke of the second push rod and the second notch, the swing path length of the movable block is greater than the elongation of the transmission rod.

[0016] The above also includes a spacing adjustment mechanism. When the movable block is restricted by solid waste and cannot swing under the pushing action of the first push rod or the second push rod, the spacing adjustment mechanism adjusts the spacing between two adjacent shredding teeth on the shredding roller to increase.

[0017] The beneficial effect of the present invention is that: by arranging multiple guide plates, if material jams occur during the process of the shredding roller shredding solid waste, the guide plates can push the solid waste stuck on the shredding roller out and guide it away from the shredding roller. In this way, no matter whether the shredding roller is in the process of shredding solid waste or spitting out solid waste, the guide plates can achieve the purpose of preventing the shredding roller from jamming.

[0028] In order to make those skilled in the art better understand the technical solution of the present invention, Figure 1 To the attached Figure 7 The present invention is further described in detail.

[0029] One embodiment of the present invention provides an anti-jamming mechanism for solid waste treatment equipment, comprising a frame 1 and a shredder box 10 arranged on the frame 1, wherein two shredder rollers 11 are arranged side by side in the shredder box 10, and the two shredder rollers 11 rotate relative to each other under the drive of a driving mechanism 12. The mechanism also includes an anti-jamming component 2, which includes two base plates 20 arranged in the shredder box 10, and each base plate 20 is sequentially installed with multiple guide plates 21 along the axial direction of the shredder roller 11. During the rotation of the shredder roller 11, the multiple guide plates 21 guide solid waste stuck on the shredder roller 11 away from the shredder roller 11.

[0030] Specifically, the frame 1 is a frame structure assembled by welding or bolting of metal profiles, on which a shredder box 10 is installed. The shredder box 10 is provided with a lower hopper 100, a shredding space 101 with two shredding rollers 11 installed, and a discharge port 102 opened at the bottom for discharging shredded solid waste, wherein the shredding roller 11 is composed of a cylindrical roller body 110 and a plurality of shredding teeth 111 installed in sequence along the axial direction on the cylindrical roller body 110. The shredding teeth 111 on the two shredding rollers 11 are alternately arranged in the axial direction, and the shredding teeth 111 have a plurality of shredding blades arranged at intervals in their own circumferential direction. During the relative rotation of the two shredding rollers 11, a shearing action can be formed between the two shredding teeth 111 at adjacent positions. That is, for the convenience of description and understanding, the relative rotation of the two shredding rollers 11 is now divided into two modes, that is, the first mode, in which the solid waste is shredded. The solid waste is shredded from the lower hopper 100 into the shredding space 101 and is sheared and shredded by the two shredding rollers 11, and then discharged from the discharge port 102; the second way is that when solid waste is stuck on the shredding roller 11, causing the shredding roller 11 to be unable to rotate in the first way, the two shredding rollers 11 rotate in the opposite direction to spit out the stuck solid waste in the reverse direction of the discharge (this way of solving the jam is the existing technology, and the specific working principle is not described in detail here. How the driving mechanism drives the two shredding rollers 11 to rotate relative to each other is also the existing technology and is not described in detail here); but if the solid waste is stuck between the two axially adjacent shredding teeth 111 of the shredding roller 11, it will be difficult to spit it out by reversing the material, and it will also cause the two shredding rollers 11 to get stuck after reversing, which requires human intervention, which undoubtedly has an adverse effect on the solid waste treatment efficiency.

[0031] Based on the above technical problems, in this embodiment, two base plates 20 are fixed by bolts in the shredding space, and the two shredding rollers 11 are located between the two base plates, and each base plate 20 corresponds to a shredding roller 11, and then a plurality of guide plates 21 are axially installed on each base plate 20, and the plurality of guide plates 21 on each base plate 20 are alternately arranged with the plurality of shredding teeth 111 on the shredding roller 11 at the corresponding position, and the guide plates 21 are sliding toward the end of the corresponding shredding roller 11 and abutting against the surface of the cylindrical roller body 110 of the shredding roller 11, that is, when there is a material jam in the shredding roller 11, the driving mechanism drives the two shredding rollers 11 to rotate in either the first or the second manner, and the guide plates 21 can hinder the solid waste stuck between the two adjacent shredding teeth 111, so that it forms a relative movement with the shredding roller 11, thereby cleaning the solid waste from the shredding roller 11.

[0032] The arrangement between each guide plate 21 and the corresponding shredding tooth 111 is the same as the arrangement between the two shredding teeth 111 at the corresponding positions on the two shredding rollers, that is, a shearing effect can also be formed. In this way, when the two shredding rollers 11 rotate in the second manner, part of the solid waste spitted out in the reverse direction can be sheared for the second time, thereby better preventing the problem of solid waste being stuck at the same position when the two subsequent shredding rollers 11 rotate in the first manner.

[0033] The beneficial effect of this embodiment is that by providing a plurality of guide plates 21, if material jams occur during the process of the shredding roller 11 shredding solid waste, the guide plates 21 can push the solid waste stuck on the shredding roller 11 out and guide it away from the shredding roller 11. In this way, no matter whether the shredding roller 11 is shredding solid waste or spitting out solid waste, the guide plates 21 can achieve the purpose of preventing the shredding roller 11 from jamming.

[0034] Preferably, in the direction of discharge of the solid waste after it is shredded, the upper and lower sides of the guide plate 21 are both inclined structures; specifically, the upper and lower sides of the guide plate 21 are arranged into an inclined structure, the low point of the inclined structure is close to the shredding roller 11, and the high point is away from the shredding roller 11, so that in the process of the solid waste stuck on the shredding roller 11 being pushed by the guide plate 21 to form a relative movement with the shredding roller 11, the inclined part of the guide plate 21 can also guide the solid waste, especially when the two shredding rollers 11 rotate in the second manner, the shredding rollers 11 cooperate with the corresponding guide plate 21 to perform secondary shearing on the solid waste, and as the solid waste spitted out in the opposite direction increases, the upper inclined structure of the guide plate 21 can temporarily guide the solid waste away from the position between the two shredding rollers 11, avoiding excessive accumulation of solid waste, thereby better solving the problem of material jamming.

[0035] Furthermore, a ring body 22 is installed between two shredding teeth 111 at adjacent positions on the shredding roller 11, and a plurality of movable blocks 23 are arranged to swing in sequence on the circumference of the ring body 22, and a first elastic member 24 is also connected between each movable block 23 and the ring body 22; along the circumference of the ring body 22, both ends of the movable block 23 are raised structures, and when the raised part at one end of the ring body 22 is squeezed by external force and swings toward the inside of the ring body 22, the raised part at the other end swings toward the outside of the ring body 22.

[0036] Specifically, in the aforementioned embodiment, the guide plate 21 is used to push the solid waste stuck between two adjacent shredding teeth 111 to move relative to the shredding roller 11. Although the stuck solid waste can be guided away from the shredding roller 11, some solid waste will rotate relative to the shredding roller 11 when pushed by the guide plate 21. In this case, the solid waste will continue to be stuck between the two adjacent shredding teeth 111 and cannot escape. When the remaining solid waste is subsequently shredded, the solid waste originally stuck between the two adjacent shredding teeth 111 and the subsequent solid waste will be superimposed, which will increase the probability that the shredding roller 11 will get stuck again.

[0037] Therefore, in this embodiment, the ring body 22 is installed on the cylindrical roller body 110 in the same installation method as the tearing teeth 111 on the cylindrical roller body 110, and a ring body 22 is installed between two adjacent tearing teeth 111, and a plurality of movable blocks 23 are evenly arranged in the circumferential direction of the ring body 22. The center position of the movable block 23 is rotatably installed on the ring body 22 by the shaft, that is, the movable block 23 can rotate on the ring body 22, wherein a first elastic member 24 is further provided between each movable block 23 and the corresponding ring body 22, and a convex structure is provided at both ends of each movable block 23. The part between the two convex structures is in an arc shape, and based on the elastic force of the first elastic member 24, the center of the arc-shaped part is in the same center as the center of the corresponding ring body 22. On the axis, the raised structure protrudes from the outer arc surface of the ring body 22, that is, when either end of the movable block 23 is squeezed by external force and swings toward the inside of the ring body 22, the other end will swing in the direction away from the outer arc surface of the ring body 22, so that the part between the two adjacent shredding teeth 111 is movable. In the process of shredding solid waste by the two shredding rollers 11, the solid waste entering between the two adjacent shredding teeth 111 will squeeze the movable block 23. When the movable block 23 swings, the solid waste between the two adjacent shredding teeth 111 can be reversely squeezed by the movable block 23 to become movable. In this way, the solid waste stuck between the two adjacent shredding teeth 111 can be more easily cleaned up by utilizing the pushing effect of the guide plate 21.

[0038] Furthermore, in the direction of material discharge, a first push rod 25 is swingably provided on the upper side of the guide plate 21, and a second elastic member 26 is also provided between the first push rod 25 and the guide plate 21; during the rotation of the shredding roller 11 to shred the solid waste, the first push rod 25 jumps on the guide plate 21 based on the pushing action of each movable block 23.

[0039] Specifically, a channel is opened in the middle of each guide plate 21 along the material feeding direction, and the acoustic swing of the channel is provided with a first push rod 25, that is, one end of the first push rod 25 is rotatably connected to the guide plate 21, and the other end is a free end, and a second elastic member 26 is also provided between the first push rod 25 and the guide plate 21. The connection position of the second elastic member 26 and the first push rod 25 can be in the middle of the first push rod 25, and based on the elastic force of the second elastic member 26, the free end of the first push rod 25 has a tendency to always stick to the surface of the cylindrical roller body 110, and the free end of the first push rod 25 extends out of a part of the channel, and the stiffness coefficient of the second elastic member 26 is smaller than the stiffness coefficient of the first elastic member 24, that is, when the movable block 23 contacts the free end of the first push rod 25, the raised part on the movable block 23 can generate a thrust on the free end of the first push rod 25, so that it is away from the surface of the arc-shaped roller body 110. The position of the movable block 23 basically does not change, so when the first rod body is squeezed by multiple movable blocks 23 in turn, a jumping effect can be generated on the guide plate 21, so that the solid waste on the guide plate 21 can be prevented from being piled up and unable to move under the jumping action of the first top plate, and the part of the free end of the first push rod 25 extending out of the channel can also play a provocative role on the solid waste between the two adjacent tearing teeth 111, so as to better clean up the stuck solid waste, and in an optional embodiment, in the feeding direction, the lower side of the guide plate 21 is swung with a second push rod 27, and the second push rod A third elastic member 28 is further provided between 27 and the guide plate 21. Based on the elastic force of the third elastic member 28, the free end of the second push rod 27 tends to always stick to the surface of the cylindrical roller body 110; in the process of the shredding roller 11 rotating to spit out solid waste, the second push rod 27 jumps on the guide plate 21 based on the pushing action of each movable block 23, that is, the second push rod 27 and the first push rod 25 are arranged symmetrically, and the structure and appearance are the same. The jumping effect can also be achieved under the squeezing action of the movable block 23. When shredding solid waste, the jumping of the second push rod 27 can also assist in cleaning stuck solid waste.

[0040] Furthermore, a first notch 29 is provided on a raised portion of the movable block 23. During the rotation of the shredding roller 11 to spit out solid waste, the first push rod 25 is first plugged into each first notch 29 in sequence and then separated. During the plugging of the first push rod 25 with any first notch 29, the first push rod 25 pushes the end of the movable block 23 corresponding to the first notch 29 to move in a direction deviating from the ring body 22.

[0041] Specifically, in the aforementioned embodiment, the raised portion on the movable block 23 is used to produce an extrusion effect on the first push rod 25, and the elastic force of the second elastic member 26 is combined to make the first push rod 25 produce a jumping effect, thereby assisting in cleaning the solid waste stuck between adjacent shredding teeth 111. However, the jumping height of the first push rod 25 depends on the raised height of the raised portion on the movable block 23, and between the two shredding rollers 11, a large gap should not be reserved between the shredding teeth 111 of one shredding roller 11 and the surface of the cylindrical roller body 110 of the other shredding roller 11, so as to reduce the situation where the solid waste cannot be sheared. That is, when the movable block 23 is squeezed by the solid waste, its swing amplitude cannot affect the rotation of the other shredding roller 11 Therefore, in this embodiment, in order to increase the swing amplitude of the first push rod 25, a first notch 29 is opened on the movable block 23. When the two shredding rollers 11 rotate in the second manner, the free end of the first push rod 25 will be plugged into and then separated from the multiple first notches 29 in sequence. During the plugging process, the first push rod 25 swings, the movable block 23 swings, and the angle between the first push rod 25 and the movable block 23 gradually becomes smaller. The first push rod 25 and the movable block 23 form a V-shaped structure, and the height of the contact part between the two gradually increases in the direction away from the ring body 22 until the free end of the first push rod 25 is disengaged from the first notch 29. In this way, the swing amplitude of the movable block 23 and the first push rod 25 is increased, thereby better The solid waste stuck between the two adjacent shredding teeth 111 is pushed out, wherein, in order to facilitate the reset of the movable block 23 under the action of the rebound force of the first elastic member 24 after the first push rod 25 is separated from the first notch 29, the swing amplitude of the movable block 23 should be smaller than the swing amplitude of the first push rod 25, and when the elastic force of the second elastic member 26 increases to a certain value, the first push rod 25 can push the movable block 23 to swing, and after the free end of the first push rod 25 is separated from the first notch 29, the end of the movable block 23 in the first notch 29 will be at a position where the free end of the first push rod 25 is closer to the surface of the ring body 22, and then the first push rod 25 is reset by the rebound force of the first elastic member 24, and the first push rod 25 is reset under the action of the rebound force of the second elastic member 26 It is also reset. In an optional embodiment, when the two shredding rollers 11 rotate in the first manner, a second notch 30 can be provided on another raised portion of the movable block 23. During the travel of the shredding rollers 11 to shred the solid waste, the second push rod 27 and each second notch 30 are first plugged in in sequence and then separated; during the travel of the second push rod 27 and any second notch 30 being plugged in, the second push rod 27 pushes the end of the movable block 23 corresponding to the second notch 30 to move in a direction deviating from the ring body 22. The specific working method is the same as the working method of the first push rod 25 and the first notch 29, and will not be elaborated on here. Its purpose is also to better push out the solid waste stuck between two adjacent shredding teeth 111.

[0042] Furthermore, a transmission rod 31 is connected between two adjacent movable blocks 23. When any movable block 23 performs a swinging motion, the movable block 23 at the adjacent position swings based on the transmission action of the transmission rod 31. The transmission rod 31 is composed of two sections that are slidably plugged into each other, and in the plug-in stroke of the first push rod 25 and the first notch 29, the swinging path length of the movable block 23 is greater than the elongation of the transmission rod 31. In the plug-in stroke of the second push rod 27 and the second notch 30, the swinging path length of the movable block 23 is greater than the elongation of the transmission rod 31.

[0043] When the first push rod 25 is plugged into any of the first notches 29, the remaining push rods 23 can also swing. Under the premise of not affecting the rotation of the shredding roller 11, the transmission rod 31 is divided into two sections that can be telescopically changed. In the plugging stroke of the first push rod 25 and the first notch 29, the swinging path length of the movable block 23 is greater than the elongation of the transmission rod 31. In the plugging stroke of the second push rod 27 and the second notch 30, the swinging path length of the movable block 23 is greater than the elongation of the transmission rod 31. That is, the swinging paths of the first push rod 25 and the second push rod 27 are both set to 10, and the telescopic amount of the transmission rod 31 is 3, which can be increased on the basis of the original movable block 23 convex part squeezing the first push rod 25 and the second push rod 27 jumping amplitude, so that the solid waste between the two adjacent shredding teeth 111 can be pushed in advance.

[0044] Another embodiment of the present invention further includes a spacing adjustment mechanism. When the movable block 23 is restricted by solid waste and cannot swing under the pushing action of the first push rod 25 or the second push rod 27, the spacing adjustment mechanism adjusts the spacing between the two shredding teeth 111 at adjacent positions on the shredding roller 11 to become larger; the spacing adjustment mechanism includes an extrusion block 32 arranged on the axial side surface of each ring body 22, each shredding tooth 111 is axially slidably arranged on the corresponding shredding roller 11, and each shredding tooth 111 is provided with an extrusion groove 33 that cooperates with the extrusion block 32 on the corresponding ring body 22, and each shredding tooth 111 is fixed with a card block 35, and a cavity is axially provided inside the cylindrical roller body 110 of the shredding roller 11, and a fourth spring is arranged in the cavity. The fourth elastic member 34 is a columnar spring, and the card block 35 is connected to the fourth elastic member 34. When the fourth elastic member 34 is axially expanded and contracted, each tearing tooth 111 can be driven to move axially. Since the fourth elastic member 34 is a columnar spring, the pitch change is basically uniform when the fourth elastic member 34 is expanded and contracted. Accordingly, the guide plate 21 is also arranged to slide axially on the base plate 20, that is, a slideway is provided on the base plate 20, and a pair of slide bars fixed to each guide plate 21 are provided in the slideway. When the position of the tearing tooth 111 changes in the axial direction, the position of the guide plate 21 can also change, thereby preventing the guide plate 21 from hindering the movement of the tearing tooth 111. After the connection, the angle between the first push rod 25 and the movable block 23 remains substantially unchanged, that is, the solid waste stuck between the adjacent shredding teeth 111 is equivalent to being in a stuck state. At this time, the ring body 22 is restricted by the connection between the first push rod 25 and the first notch 29 and is difficult to rotate with the shredding roller 11 (under normal circumstances, since the blocking block 35 is stuck on the fourth elastic member 34, the fourth elastic member 34 can rotate with the shredding roller 11, and the shredding teeth 111 can rotate with the cylindrical roller body 110, and the extrusion block 32 on the ring body 22 is connected with the extrusion groove 33 corresponding to the shredding teeth 111. Based on the elastic force restriction of the fourth elastic member 34, the ring body 22 can rotate with the shredding roller 11). After the ring body 22 becomes difficult to rotate, the shredding roller 11 continues to rotate. , the extrusion block 32 and the extrusion groove 33 form a mutual extrusion action (the wedge-shaped matching structure realizes the extrusion action), and the tearing teeth 111 will be subjected to a radial thrust, and the distance between the two adjacent tearing teeth 111 becomes larger, so the force that originally stuck the solid waste is released, and the first push rod 25 is plugged into the first notch 29, so that the first push rod 25 and the movable block 23 can continue to swing, and the guide plate 21 can be used to smoothly clean up the solid waste. After the second push rod 27 is plugged into any second notch 30, the angle between the second push rod 27 and the movable block 23 is basically unchanged, and the solid waste stuck between the adjacent tearing teeth 111 is equivalent to being in a stuck state. The solution is the same as above, and no further details will be given here.

[0045] The above descriptions of certain exemplary embodiments of the present invention are provided by way of illustration only.
