Description

Technical Field

[0001] The invention relates to the field of garbage processing equipment, and in particular to a combined industrial garbage shredding device and method. Background Art

[0002] As the scale of industrial production continues to expand, the amount of industrial waste generated has also exploded. Industrial waste is complex and contains various metals, plastics, wood, fibers and other materials. If it is not properly treated and randomly piled or landfilled, it will cause serious pollution to the soil, water and air, posing a huge threat to the ecological environment and human health.

[0003] In order to achieve the reduction, harmlessness and resource utilization of industrial waste, crushing and processing is a key preliminary step. Traditional garbage shredders expose many defects when facing this type of material. Due to the special shape of the material, the material is difficult to be effectively grasped and fixed, and cannot fully interact with the shredding teeth, resulting in difficulty in shredding the material smoothly. This requires the shredder to consume a lot of time and energy to complete the material crushing work, seriously reducing the overall shredding efficiency and increasing the processing cost and time cost. At the same time, the structural design of traditional shredders is also prone to jamming problems when processing such materials. During the shredding operation, due to the different hardness of the materials, incompletely crushed materials or foreign objects are easily stuck in the gap between the shredding teeth, causing the shredder to stop, and the shredding rollers need to be reversed to remove the foreign objects, which not only reduces production efficiency, but also increases the maintenance workload and cost of the equipment. Summary of the invention

[0030] like Figures 1 to 6As shown, an embodiment of the present invention provides an industrial garbage combined shredding device, including a shell 100, a shredding mechanism and an adjusting mechanism. The shell 100 is fixedly arranged, and the shredding mechanism includes two rollers 101 and two tearing assemblies. The two rollers 101 are rotatably arranged in the shell 100, and the rotation axes of the two rollers 101 extend along a first direction, which is a horizontal direction. The two rollers 101 are located in the same horizontal plane, and the two rollers 101 are arranged in sequence along a second direction and can approach or move away from each other along the second direction. The second direction is perpendicular to the first direction and both are horizontal directions. The cross-section of each roller 101 perpendicular to the first direction is an ellipse, and the center point of the ellipse is on the rotation axis of the corresponding roller 101, and the two ellipses are symmetrically arranged about a first plane, which is vertically arranged and parallel to the axis of the roller 101. The garbage will be shredded when passing between the two rollers 101; each tearing assembly is correspondingly arranged on a roller 101, and the two tearing assemblies are used to tear the garbage between the two rollers 101; the adjusting mechanism is used to control the abutment pressure between the two rollers 101.

[0031] The cross section of the roller 101 is elliptical, so that each roller 101 has a long axis and a short axis, the two rollers 101 are symmetrical about the first plane, and the short axes of the two rollers 101 are also symmetrical about the first plane. During the rotation of the two rollers 101, the projections of the two long axes of the two rollers 101 in the first direction will form a trumpet shape with a large mouth and a small mouth. When the large mouth is located above the small mouth, the garbage above the two rollers 101 will enter between the two rollers 101 better, and when the distance between the large mouth and the small mouth in the vertical direction decreases, the larger cylindrical shape above the two rollers 101 Garbage will be more easily squeezed and crushed by the two rollers 101, thereby improving the overall crushing efficiency; a tearing component is provided, so that the crushed garbage between the two rollers 101 can be further torn into pieces, thereby improving the garbage crushing effect; an adjusting mechanism is provided, and the two rollers 101 are slidingly arranged on the shell 100 along the second direction, which can increase the squeezing force of the two rollers 101 on the garbage between them, can crush garbage with higher hardness, and improve the quality of garbage crushing; at the same time, the distance between the two rollers 101 is adjustable, and garbage with particularly high hardness will not get stuck in the rollers 101, and the rollers 101 can continue to work.

[0032] In this embodiment, each tearing assembly includes a plurality of first ring plates 102 and a plurality of second toothed rings, and the plurality of first ring plates 102 and the second toothed rings are sleeved on the corresponding rollers 101, and the plurality of first ring plates 102 and the second toothed rings are alternately distributed along the first direction on the corresponding rollers 101; the first ring plates 102 on one roller 101 can contact the circumferential surface of the other roller 101, and when the garbage passes between the two rollers 101, the first ring plates 102 and the second toothed rings on the two rollers 101 can first contact the garbage, thereby reducing the force area of ​​the garbage without reducing the squeezing force between the two rollers 101, and the pressure on the garbage becomes greater, making it easier to break.

[0033] In this embodiment, a groove 103 having the same number as the second gear ring is formed on the circumferential surface of each rotating roller 101, and the plurality of grooves 103 are arranged along the first direction. The second gear ring includes two arc plates 104 and two groups of elastic plates 105. The two arc plates 104 are slidably arranged in one groove 103, and the curvature of the two arc plates 104 is consistent with the curvature of the rotating roller 101 at the position. The two arc plates 104 are rotationally symmetrical about the axis of the corresponding rotating roller 101. Each group of elastic plates 105 corresponds to one arc plate 104, and the two groups of elastic plates 105 and the two arc plates 104 are arranged in the same groove 103. There are a plurality of elastic plates 105 in each group of elastic plates 105, and one end of the elastic plate 105 in each group is connected to the rotating roller 101, and the other end of the elastic plate 105 is connected to the rotating roller 101. The end is connected with the inner arc surface of the corresponding arc plate 104; the arc plate 104 on each roller 101 abuts against the circumferential surface of the other roller 101. When the roller 101 rotates, if the hardness of the garbage entering between the two rollers 101 is too high so that the first ring plate 102 and the second gear ring cannot tear it into pieces, the two rollers 101 will move away from each other to allow the garbage with too high hardness to pass through, thereby avoiding the two rollers 101 from getting stuck; if the garbage with too high hardness contacts the arc plate 104, the arc plate 104 will move in the groove 103 in the direction close to the axis of the roller 101 and compress the elastic plate 105, so that the garbage passes through. At this time, the distance between the two rollers 101 changes little, and other garbage between the two rollers 101 continues to be squeezed and shredded, thereby avoiding excessive garbage from being incompletely shredded.

[0034] In this embodiment, the two end surfaces of each first ring plate 102 on one of the rollers 101 are in sliding contact with one end surface of the adjacent first ring plate 102 and the arc plate 104 on the other roller 101, and the two end surfaces of each arc plate 104 on the roller 101 are in sliding contact with one end surface of the adjacent first ring plate 102 and the arc plate 104 on the other roller 101. When the first ring plate 102 is in sliding contact with the corresponding first ring plate 102 and the arc plate 104, the garbage therebetween will be crushed due to the shear force, thereby improving the crushing efficiency and crushing quality.

[0035] In this embodiment, teeth are provided on the circumferential surface of each first ring plate 102 and the outer arc surface of each arc plate 104. When the teeth on the first ring plate 102 and the arc plate 104 contact the corresponding roller 101, they can further shred the garbage shredded by the shear force.

[0036] In this embodiment, a feed hopper 106 is provided on the housing 100, and two guide plates 107 are provided in the housing 100. The two guide plates 107 are located below the feed hopper 106 and above the two rollers 101. The two guide plates 107 are symmetrically arranged about the first plane, and the two guide plates 107 are inclined relative to the horizontal plane. The side of the two guide plates 107 close to the first plane is closer to the roller 101 than the other side, and the spacing between the two guide plates 107 close to the first plane is smaller than that between the two guide plates 107 and the first plane. At the minimum spacing between the axes of the two rollers 101, when the distance between the axes of the two rollers 101 is the shortest, the distance between the roller 101 and the guide plate 107 directly above it is the smallest and can be ignored; when putting garbage into the shell 100, the garbage can be placed in the feed hopper 106 first, and the garbage in the feed hopper 106 moves to the intersection of the two rollers 101 under the action of the guide plate 107, and the garbage entering the roller 101 will not move in the direction away from the first plane.

[0037] In this embodiment, four adjusting mechanisms are provided, each of which corresponds to one end of the roller 101. Each adjusting mechanism includes a slide 108, a threaded rod 109, a first motor 110 and a spring 111. The slide 108 is slidably arranged on the shell 100 along the second direction, and the slide 108 is rotatably connected with one of the rollers 101. A slide groove 112 is provided on the shell 100, and the slide groove 112 penetrates the shell 100 along the first direction. An extension shaft is provided on the end surface of each roller 101, and the extension shaft is coaxial with the rotation axis of the corresponding roller 101. The extension shaft is slidably arranged in the slide groove 112, and the extension shaft extends out of the shell 100. The slide 108 is sleeved on the corresponding extension shaft, and the slide 108 is rotatably connected with the extension shaft. A second motor 115 is provided on each slide 108, and the second motor 1 15 is connected with the corresponding extension shaft, and can drive the corresponding roller 101 to rotate through the extension shaft, the threaded rod 109 is threadedly connected with the shell 100, and the threaded rod 109 slides on the shell 100 along the second direction, and the first motor 110 is arranged on the shell 100, and is used to drive the threaded rod 109 to rotate; the spring 111 is arranged between the threaded rod 109 and the slide seat 108, and the two ends of the spring 111 are respectively connected with the threaded rod 109 and the slide seat 108, and the spring 111 is retracted and retracted along the second direction; when it is necessary to adjust the abutting pressure between the two rollers 101, the first motor 110 will drive the threaded rod 109 to approach the slide seat 108, the spring 111 will be compressed, the elastic force of the spring 111 on the slide seat 108 will increase, the abutting pressure between the two rollers 101 will increase, and the crushing effect of the garbage will be better.

[0038] In this embodiment, the industrial waste combined shredding device further comprises a screen 113 and four connecting plates 114. The screen 113 is slidably arranged in the housing 100 along the vertical direction, and the screen 113 is located below the roller 101. The garbage crushed by the roller 101 falls onto the screen 113 for screening. The garbage of qualified size is screened out from the screen 113, and the unqualified garbage is left on the screen 113. One end of each connecting plate 114 is rotatably connected to an end face of the roller 101. The four connecting plates 114 are rotatably connected to the two end faces of the two rollers 101 in a one-to-one correspondence, and the connecting plates 114 are rotatably connected to the two end faces of the two rollers 101, and the connecting plates 114 are rotatably connected to the two end faces of the two rollers 101 in a one-to-one correspondence. 01 coincides with the rotation axis of the roller 101 itself, and the connecting plate 114 is rotatably connected to the screen 113 at one end away from the roller 101, and the rotation axis of the connecting plate 114 on the screen 113 extends along the first direction, and each connecting plate 114 is sleeved on an extension shaft, and the connecting plate 114 is rotatably connected to the corresponding extension shaft; when the rotation axes of the two rollers 101 are closest to each other, the connecting plate 114 extends along the vertical direction, and the roller 101 rotates, and its rotation axis slides along the second direction, and at the same time, the screen 113 moves up and down through the connecting plate 114, and qualified garbage on the screen 113 is more likely to fall off.

[0039] A gravity sensor is provided on the screen 113, and the gravity sensor is electrically connected to the first motor 110. When the weight on the screen 113 reaches a preset value, the gravity sensor transmits a signal to the first motor 110 and the second motor 115. The first motor 110 starts to drive the threaded rod 109 to approach the slide seat 108, the elastic force of the spring 111 increases, and the squeezing pressure between the two rollers 101 increases. At this time, the second motor 115 stops and the garbage on the screen 113 is taken out for secondary crushing.

[0040] In this embodiment, the middle part of the screen 113 is raised, and the raised part extends along the first direction. The raised part is located on the first plane. The garbage falling onto the screen 113 slides under the guidance of the inclined surface of the screen 113, and qualified garbage is easier to be screened out.

[0041] The working principle of the combined industrial waste shredding device provided in the above embodiment is as follows:

[0042] First, start the second motor 115, which drives the corresponding roller 101 to rotate. The two rollers 101 rotate in opposite directions. The roller 101 drives the first ring plate 102 and the arc plate 104 to rotate. When the arc plate 104 contacts the other roller 101, the arc plate 104 will slide in the groove 103 and compress the elastic plate 105. Then, add garbage into the feed hopper 106. After the garbage enters the feed hopper 106, it moves between the two rollers 101 under the guidance of the guide plate 107. Under the action of the first ring plate 102 and the arc plate 104, the garbage is sheared and broken, and the teeth on the first ring plate 102 and the arc plate 104 will further crush the garbage.

[0043] When the hardness of the garbage is too high and the squeezing force between the two rollers 101 is insufficient to crush the garbage, the garbage entering between the two rollers 101 will push the two rollers 101 to slide in the chute 112 and move away from each other, and the gap between the two rollers 101 increases, allowing the garbage to pass through and fall onto the screen 113. Then, the two rollers 101 move closer to each other under the action of the spring 111, and then crush other garbage with lower hardness; if the garbage with higher hardness happens to contact the arc plate 104, the garbage will push the arc plate 104 to slide in the groove 103, and the elastic plate 105 will be further compressed. The distance between the two rollers 101 remains basically unchanged, and other garbage with lower hardness can continue to be crushed.

[0044] In the process of the two rollers 101 approaching or moving away from each other, the two rollers 101 drive the screen 113 to move up and down through the connecting plate 114, and the garbage that falls on the screen 113 after being crushed is easier to be screened out from the screen 113. As the amount of unqualified garbage on the screen 113 increases, the gravity sensor on the screen 113 controls the start and stop of the first motor 110 and the second motor 115 according to the detected data; when the data detected by the gravity sensor reaches the preset value, the first motor 110 starts, the first motor 110 drives the threaded rod 109 to rotate, the threaded rod 109 moves toward the direction close to the roller 101, the spring 111 between the threaded rod 109 and the slide 108 is compressed, the elastic force of the spring 111 on the roller 101 increases, the extrusion force between the two rollers 101 increases, and the second motor 115 stops at the same time, the two rollers 101 no longer crush the garbage, then, take out the garbage on the screen 113 for secondary crushing, at this time the extrusion force between the two rollers 101 has increased, and the garbage with relatively higher hardness can be crushed.

[0045] The present invention also provides a combined shredding method for industrial waste, comprising the following steps:

[0046] S100, start the two rollers 101 to rotate around their respective axes; start the second motor 115, the second motor 115 drives the corresponding rollers 101 to rotate, the two rollers 101 rotate in opposite directions, and the two rollers 101 can transport the garbage above them to the position where they contact each other.

[0047] S200, add garbage into the housing 100; put the garbage to be processed into the feed hopper 106, and the garbage in the feed hopper 106 moves between the two rollers 101 under the action of the guide plate 107 and falls onto the two rollers 101.

[0048] S300, the two rollers 101 rotate and send the garbage in contact with them into the space between them for extrusion and crushing by cooperating with the tearing assembly; the extrusion force of the two rollers 101 is adjusted by the adjusting mechanism to make the garbage crushed more thoroughly; the second motor 115 drives the rollers 101 to rotate, and the garbage on the rollers 101 is crushed under the extrusion of the two rollers 101, and at the same time, under the action of the first ring plate 102 and the arc plate 104, the garbage is crushed more thoroughly; for garbage of different hardness, the spring 111 is compressed by rotating the threaded rod 109, the elastic force of the spring 111 on the roller 101 is increased, and the extrusion force between the two rollers 101 is increased, which is convenient for crushing garbage with greater hardness. At the same time, garbage with greater hardness will not be stuck between the two rollers 101, reducing the shutdown frequency and improving the crushing efficiency.

[0049] S400, the crushed garbage falls under the two rollers 101; after the rollers 101 crush the garbage, qualified garbage and unqualified garbage will fall onto the screen 113, qualified garbage will be screened out from the screen 113, and unqualified garbage will remain on the screen 113. When the garbage on the screen 113 accumulates to a certain extent, it will trigger the start of the first motor 110, and the first motor 110 will drive the threaded rod 109 to rotate and compress the spring 111, so that the extrusion force between the two rollers 101 increases, thereby improving the crushing effect.

[0050] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
