Description

Technical Field

[0001] The present application relates to the technical field of solid waste treatment, and in particular to a solid waste pretreatment device. Background Art

[0002] Solid waste usually includes waste plastics, waste metals, waste glass, etc. These solid wastes usually need to be pre-processed, such as crushing and screening. The importance of solid waste crushing is to break down large pieces of waste into fine particles, which not only helps to improve recycling rate and energy recovery efficiency, but also reduces the space and cost requirements during storage, transportation and treatment, thereby promoting the effective use of resources and environmental protection. For some hazardous wastes or wastes that need to be handled safely, crushing can reduce their sharp or large parts and reduce the danger during the treatment process.

[0003] The existing solid waste pretreatment device usually puts the solid waste into a crushing box and starts the motor, which drives the crushing roller to crush the solid waste in the crushing box. However, some solid wastes are relatively elastic or difficult to crush, which makes the solid waste pretreatment device unable to fully crush these solid wastes at one time. Therefore, after the crushing is completed, manual sorting is performed and the solid wastes are returned to the device for re-crushing. This additional manual sorting and re-processing process increases the labor intensity, thereby affecting the pretreatment efficiency of solid wastes. Summary of the invention

[0033] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0034] The solid waste pretreatment device according to the embodiment of the present application is described below with reference to the accompanying drawings.

[0035] like Figure 1-Figure 10 As shown, the solid waste pretreatment device of the embodiment of the present application may include a crushing shell 1, a first motor 2, a first fixed connection block 3, a second fixed connection block, a third fixed connection block and two crushing assemblies 4.

[0036] The crushing shell 1 is provided with a feed port 10 and a discharge port 11 , and the discharge port 11 is provided with a discharge screen 110 .

[0037] It should be noted that the crushing shell 1 described in this embodiment is provided with a bracket 12, and the crushing shell 1 is supported by the bracket 12, so as to facilitate the unloading of the crushed solid waste (hereinafter referred to as material).

[0038] In the embodiment of the present application, the discharge screen 110 is used to restrict insufficiently crushed materials in the crushing assembly 4 when the materials rotate to the discharge port 11 , thereby preventing insufficiently crushed materials from leaking out of the discharge port 11 .

[0039] The first motor 2 is arranged on the crushing shell 1 .

[0040] In the embodiment of the present application, the first motor 2 is used to control the rotation of the crushing assembly 4, control the feeding of the crushing assembly 4, and control the material that is not fully crushed by the crushing assembly 4 to rotate from the discharge port 11 to the feed port 10, and crush it again with the new material, so as to achieve sufficient crushing of the material.

[0041] One end of the first fixed connection block 3 is rotatably connected to one side of the crushing shell 1 and is connected to the output shaft of the first motor 2, and the other end of the first fixed connection block 3 is connected to the corresponding crushing assembly 4; one end of the second fixed connection block is rotatably connected to the other side of the crushing shell 1, and the other end of the second fixed connection block is connected to the corresponding crushing assembly 4.

[0042] It can be understood that the first fixed connection block 3, the second fixed connection block (not shown in the figure) and the third fixed connection block (not shown in the figure) are of the same shape and size, but are connected in different positional relationships. By setting the first fixed connection block 3, the second fixed connection block and the third fixed connection block, the first motor 2 can drive the two crushing assemblies 4 to rotate through the first fixed connection block 3, the second fixed connection block and the third fixed connection block, thereby controlling the rotation feeding of the crushing assembly 4 and improving the crushing efficiency of the device.

[0043] The two crushing assemblies 4 are cross-arranged and connected via a third fixed connection block.

[0044] It should be noted that the two crushing assemblies 4 described in this embodiment are cross-arranged, and the cross-arrangement means that the two crushing assemblies 4 are cross-arranged in the crushing shell 1, which can be a right-angle cross or an oblique cross, and through the cross-arrangement of the two crushing assemblies 4, the crushing assemblies 4 are rotated in turn to receive the material from the feed port 10, thereby improving the pre-treatment efficiency of the device for the material.

[0045] The crushing assembly 4 may include a crushing drum 40 , a plurality of screening rollers 41 , two feed cover plates 42 , two crushing screens 43 , a crushing mechanism 44 and a joint control mechanism 45 .

[0046] It should be noted that the crushing barrel 40 described in this embodiment is I-shaped, the diameter of the middle part of the crushing barrel 40 is smaller than the diameter of the two end parts, and the middle part of the screening roller 41 is rotatably connected to the middle outer side of the crushing barrel 40, so as to facilitate the crushing mechanism 44 and the linkage control mechanism 45 to control the rotation of the screening roller 41, facilitate the crushing work of the crushing mechanism 44, and facilitate the screening and unloading of materials. In addition, the crushing barrels 40 respectively included in the two crushing components 4 are fixed by a third fixed connecting block, so as to ensure the rotation control effect of the first motor 2 on the two crushing components 4.

[0047] The plurality of screening rollers 41 are connected to rotate in the same direction in sequence, the middle portions of the screening rollers 41 are connected to rotate with the crushing drum 40 , and the ends of the screening rollers 41 are connected to rotate with the feed cover plate 42 .

[0048] In the embodiment of the present application, the screening roller 41 is rotatably connected with the crushing screen 43 to control the rotation of the crushing screen 43 on the feed cover 42 and the crushing drum 40, so as to rotationally screen the material in the crushing screen 43, and by connecting the screening roller 41 with the crushing screen 43, it is possible to prevent the material from blocking the screening mesh 432 of the crushing screen 43, thereby ensuring the screening efficiency of the material.

[0049] It should be noted that the multiple screening rollers 41 described in this embodiment are connected to rotate in the same direction in sequence, which means that one or more transmission wheels 411 are respectively provided on a single screening roller 41, and the transmission belt 412 is sequentially sleeved on the corresponding transmission wheels 411 on each screening roller 41. When one screening roller 41 rotates clockwise to drive the crushing screen 43 to rotate, the transmission wheel 411 and the transmission belt 412 can drive another screening roller 41 to rotate clockwise, and drive the corresponding crushing screen 43 to rotate, so that multiple screening rollers 41 are connected to rotate in the same direction in sequence, thereby ensuring the rotation effect of the crushing screen 43 and the material screening effect.

[0050] The two feed cover plates 42 are respectively connected to the crushing shell 1 in a rotatable and sealed manner, and are respectively connected to the feed port 10 and the discharge port 11 in a rotatable manner.

[0051] It should be noted that a material level meter (not shown in the figure) is provided on the feed cover plate 42 described in this embodiment to avoid excessive material, which causes the material on the feed cover plate 42 to directly drop the uncrushed material into the crushing shell 1 after the crushing assembly 4 rotates, thereby affecting the crushing quality of the material.

[0052] It should be noted that the feed cover plate 42 described in this embodiment is divided into a feed portion 420 and an extension portion 421. The feed portion 420 is a normal feed opening, and the extension portion 421 is designed for the two crushing components 4 of the device to share one feed port 10, so that the device does not need to open more feed ports 10, and does not need to add more related feeding equipment and operation controls at different feed ports 10, thereby reducing the production cost and use cost of the device.

[0053] One end of the two crushing screens 43 is rotatably sealed and connected to the crushing drum 40 respectively, the other end of the crushing screens 43 is rotatably sealed and connected to the feed cover plate 42 respectively, and the screening rollers 41 are rotatably plugged into the crushing screens 43 respectively.

[0054] It can be understood that, by providing the crushing screen 43 , the leaking portion between the feed cover plate 42 and the crushing drum 40 can be covered, and under the rotation of the screening roller 41 , the fully crushed material can be screened out.

[0055] The crushing mechanism 44 is rotatably disposed on the crushing drum 40 .

[0056] In the embodiment of the present application, the crushing mechanism 44 is used to crush the uncrushed and insufficiently crushed materials at both ends of the crushing drum 40, thereby ensuring the crushing quality of the materials and improving the pretreatment efficiency of the device.

[0057] One end of the joint control mechanism 45 is transmission-connected to the crushing mechanism 44 , and the other end of the joint control mechanism 45 is transmission-connected to the screening roller 41 .

[0058] It can be understood that, by providing the joint control mechanism 45, the use of the motor is reduced and the use cost of the device is reduced.

[0059] Specifically, in the actual operation process, the relevant personnel use a conveyor (not shown in the figure) to transport the material from the feed port 10 to the upper half of the first crushing assembly 46 (two crushing assemblies 4, one is the first crushing assembly 46, and the other is the second crushing assembly 47) (that is, when a feed cover plate 42 in the first crushing assembly 46 is covered on the feed port 10, it is divided into an upper half and a lower half with the crushing barrel 40 as the dividing line), and the material level meter set on the feed cover plate 42 detects the material signal and transmits it to the controller (not shown in the figure). ), the controller controls the conveyor to stop conveying materials and starts the crushing mechanism 44, the crushing mechanism 44 crushes the materials in the upper half, the crushed materials fall into the lower half of the first crushing assembly 46, and the materials that meet the crushing specifications leak out of the crushing shell 1 from the discharge screen 110 of the discharge port 11 connected to the other feed cover plate 42, and the insufficiently crushed materials (that is, the materials that do not meet the crushing specifications) are retained in the lower half by the discharge screen 110, thereby completing the preliminary crushing of the materials by the first crushing assembly 46.

[0060] When the crushing mechanism 44 is working, it drives the joint control mechanism 45 to rotate, and drives the multiple screening rollers 41 to rotate clockwise. The screening rollers 41 are rotatably connected with the crushing screen 43, and respectively drive the crushing screens 43 in the upper and lower parts of the first crushing component 46 to rotate on the feed cover 42 and the crushing barrel 40, so that the uncrushed but specified material in the upper part of the first crushing component 46 and the crushed and specified material in the lower part are screened out, and screened into the crushing shell 1, and discharged from the discharge screen 110 and the quick discharge port 13.

[0061] The controller controls the first motor 2 to do work, and the first motor 2 drives the two crushing components 4 to rotate. The lower half of the first crushing component 46 rotates to drive the insufficiently crushed materials to move in the crushing shell 1. When a feeding cover plate of the second crushing component 47 is connected with the feed port 10, the controller controls the conveyor to transport materials to the upper half of the second crushing component 47, and after repeating the above-mentioned preliminary crushing operation of the first crushing component 46, the controller controls the first motor 2 to continue to rotate, so that the feeding cover plate 42 of the lower half of the first crushing component 46 is connected with the feed port 10, and the insufficiently crushed materials in the lower half of the first crushing component 46 are crushed again with the newly fed materials. When the crushing mechanism 44 crushes the lower half of the materials of the first crushing component 46, the controller controls the crushing mechanism 44 to rotate in the opposite direction, thereby ensuring the crushing effect of the materials.

[0062] The second crushing assembly 47 repeats the re-crushing operation of the first crushing assembly 46, and this reciprocating process completes the full crushing of the material by the device, thereby improving the crushing effect of the material by the device.

[0063] In addition, when the first crushing assembly 46 is feeding and crushing the second crushing assembly 47, the crushing mechanism 44 of the first crushing assembly 46 continues to work and continuously drives the crushing screen 43 to rotate, thereby continuously screening the material in the lower half of the first crushing assembly 46, and when the first crushing assembly 46 is feeding, the crushing mechanism 44 stops working to prevent the first crushing assembly 46 from feeding and crushing at the same time, causing the upper and lower halves of the first crushing assembly 46 to be filled with materials, affecting the material crushing and material screening effects. Similarly, the second crushing assembly 47 is the same as the above operation of the first crushing assembly 46. Thereby improving the screening effect of the material and improving the pre-treatment efficiency of the device for the material.

[0064] In one embodiment of the present application, Figure 4 and Figure 5 As shown, the screening roller 41 may include an inserting protrusion 410 , a material blocking plate 413 , a plurality of transmission wheels 411 and a plurality of transmission belts 412 .

[0065] Among them, the plug-in protrusions 410 are rotatably plugged with the crushing screen 43 respectively, the baffle plates 413 are respectively arranged on one side of the screening roller 41, one end of the baffle plate 413 is connected to the feed cover 42, and the other end of the baffle plate 413 is connected to the crushing barrel 40, and the baffle plates 413 are respectively abutted against the crushing screen 43, a plurality of transmission wheels 411 are respectively arranged on the screening roller 41, and a plurality of transmission belts 412 are respectively rotatably sleeved with the corresponding transmission wheels 411.

[0066] It should be noted that, the baffle plates 413 described in this embodiment are multiple, and the multiple baffle plates 413 are respectively arranged to surround one side of the screening roller 41, one end of the baffle plate 413 is covered and connected with the supporting connecting block 422 arranged on the feed cover plate 42, and the other end of the baffle plate 413 is covered and connected with the crushing cylinder 40, so that the feed cover plate 42 is limited and fixed on the crushing cylinder 40 by the multiple baffle plates 413, and the setting of the baffle plate 413 prevents materials from entering the interior of the baffle plate 413 to affect the rotational connection of the plug-in protrusion 410 to the crushing screen 43, thereby ensuring the rotational screening effect of the crushing screen 43.

[0067] It can be understood that, by providing a plurality of transmission belts 412 and a plurality of transmission wheels 411 , the same-direction rotation connection between each screening roller 41 is achieved, thereby ensuring the screening effect of the crushing screen 43 .

[0068] In one embodiment of the present application, Figure 4-Figure 8 As shown, the feed cover plate 42 may include a plurality of supporting connection blocks 422 and limiting slide grooves 400 .

[0069] Among them, multiple supporting connecting blocks 422 are respectively arranged inside the feed cover plate 42, and one end of the screening roller 41 is rotatably connected to the supporting connecting blocks 422, a limiting slide groove 400 is opened at the end of the feed cover plate 42, and one end of the crushing screen 43 is rotatably connected to the limiting slide groove 400, and the other end of the crushing screen 43 is rotatably connected to the limiting slide groove 400 opened at the end of the crushing barrel 40.

[0070] It should be noted that the feed cover plate 42 described in this embodiment is arranged to be through-connected from top to bottom, so as to ensure that the material enters the feed cover plate 42 from the feed port 10 and enters the area enclosed by the crushing screen 43 from the feed cover plate 42 .

[0071] In one embodiment of the present application, Figure 4-Figure 8 As shown, the crushing screen 43 may include a limiting bar 430 , a plurality of limiting beads 431 and a screening mesh 432 .

[0072] Among them, the limit bars 430 are respectively arranged on both sides of the crushing screen 43, and multiple limit beads 431 are respectively connected to the limit bars 430. The limit beads 431 are respectively slidably connected to the limit slide grooves 400. The screening meshes 432 are respectively opened on the crushing screen 43, and the plug-in protrusions 410 are respectively rotatably plugged with the corresponding screening meshes 432.

[0073] It should be noted that the crushing screen 43 described in this embodiment is made of rubber material, so as to facilitate the rotation of the crushing screen 43.

[0074] It can be understood that, by providing the limiting beads 431 , the crushing screen 43 can be limited in the limiting slide groove 400 , and the friction between the crushing screen 43 and the limiting slide groove 400 can be reduced.

[0075] In one embodiment of the present application, Figure 4-Figure 8 As shown, the crushing mechanism 44 may include a second motor 440 and two crushing rollers 441 .

[0076] The second motor 440 is disposed on the crushing drum 40 , and the output shaft of the second motor 440 is connected to the crushing roller 441 . The two crushing rollers 441 are respectively rotatably connected to the crushing drum 40 , and the two crushing rollers 441 are meshingly connected.

[0077] It should be noted that one end of the second motor 440 is fixed on the crushing drum 40 , so as to ensure that the second motor 440 drives the crushing roller 441 .

[0078] In one embodiment of the present application, Figure 4-Figure 8 As shown, the linkage control mechanism 45 may include a first gear 450 , a second gear 451 and a third gear 452 .

[0079] Among them, the first gear 450 is arranged on the output shaft of the second motor 440, and the output shaft of the second motor 440 is connected to one of the crushing rollers 441, the second gear 451 is rotatably arranged on the crushing drum 40 and connected to the other crushing roller 441, and the first gear 450 is meshingly connected with the second gear 451, the third gear 452 is rotatably arranged on the crushing drum 40, and the third gear 452 is meshingly connected with the first gear 450, and a driving wheel is arranged at the bottom of the third gear 452, and the driving wheel and the transmission wheel 411 arranged on the screening roller 41 are rotatably sleeved through a transmission belt 412.

[0080] It can be understood that the rotation of the second motor 440 drives the first gear 450 and a crushing roller 441 to rotate, and the first gear 450 engages the second gear 451, thereby driving the other crushing roller 441 to rotate, thereby reducing the use of motors and reducing the use cost of the device. In addition, the rotation of the first gear 450 drives the third gear 452 to rotate, and the third gear 452 drives a screening roller 41 to rotate through a driving wheel (the driving wheel is not shown in the figure, the driving wheel and the transmission wheel 411 belong to the same type of component, and the two are only different in name) and a transmission belt 412 arranged at the bottom, and one screening roller 41 drives other screening rollers 41 to rotate in the same direction in turn, thereby further reducing the use cost of the device.

[0081] In one embodiment of the present application, Figure 2 and Figure 5As shown, a quick discharge port 13 is provided on the crushing shell 1 , and the quick discharge port 13 is respectively arranged on both sides of the crushing screen 43 , and the feed cover plate 42 is not connected with the quick discharge port 13 .

[0082] It can be understood that the material screened out by the crushing screen 43 falls into the crushing shell 1 and falls out through the quick discharge port 13 at the bottom of the crushing shell 1. In addition, the feed cover plate 42 is not connected to the quick discharge port 13, thereby preventing insufficiently crushed material from falling directly outside the crushing shell 1 and affecting the material crushing quality, thereby improving the pretreatment efficiency of the device.

[0083] Specifically, in the actual operation process, relevant personnel use the conveyor to convey the material from the feed port 10 to the upper half of the first crushing assembly 46. After the material level meter set on the feed cover plate 42 detects the material signal, it is transmitted to the controller. The controller controls the conveyor to stop conveying the material and starts the second motor 440. The second motor 440 drives the first gear 450 and the second gear 451 to rotate, thereby driving the crushing roller 441 to rotate and do work, and crushes the material in the upper half. The crushed material falls to the lower half of the first crushing assembly 46, and the material that meets the crushing specifications leaks out of the crushing shell 1 from the discharge screen 110 of the discharge port 11 connected to another feed cover plate 42. The insufficiently crushed material is retained in the lower half by the discharge screen 110, thereby completing the preliminary crushing of the material by the first crushing assembly 46.

[0084] When the second motor 440 rotates to drive the first gear 450 to rotate, the first gear 450 drives the third gear 452 to rotate, and the third gear 452 drives multiple screening rollers 41 to rotate clockwise through the transmission wheel 411 and the transmission belt 412, so that the screening rollers 41 and the crushing screen 43 are rotated and plugged, and respectively drive the crushing screens 43 in the upper and lower parts of the first crushing component 46 to rotate on the feed cover 42 and the crushing barrel 40, so that the materials in the upper half of the first crushing component 46 that are not crushed but meet the specifications and the materials in the lower half that have been crushed and meet the specifications are screened out, and screened into the crushing shell 1, and discharged from the discharge screen 110 and the quick discharge port 13.

[0085] The controller controls the first motor 2 to do work, and the first motor 2 drives the two crushing components 4 to rotate. The lower half of the first crushing component 46 rotates to drive the insufficiently crushed materials to move in the crushing shell 1. When a feed cover plate 42 of the second crushing component 47 is connected with the feed port 10, the controller controls the conveyor to convey materials to the upper half of the second crushing component 47, and after repeating the above-mentioned preliminary crushing operation of the first crushing component 46, the controller controls the first motor 2 to continue to rotate, so that the feed cover plate 42 of the lower half of the first crushing component 46 is connected with the feed port 10, and the insufficiently crushed materials in the lower half of the first crushing component 46 are crushed again with the newly fed materials. When the crushing mechanism 44 crushes the lower half of the materials of the first crushing component 46, the controller controls the crushing roller 441 to rotate in the opposite direction, thereby ensuring the crushing effect of the materials.

[0086] The second crushing assembly 47 repeats the re-crushing operation of the first crushing assembly 46, and this reciprocating process completes the full crushing of the material by the device, thereby improving the crushing effect of the material by the device.

[0087] In addition, when the first crushing assembly 46 is feeding and crushing the second crushing assembly 47, the crushing mechanism 44 of the first crushing assembly 46 continues to work and continuously drives the crushing screen 43 to rotate, thereby continuously screening the material in the lower half of the first crushing assembly 46, and when the first crushing assembly 46 is feeding, the second motor 440 stops working to prevent the first crushing assembly 46 from feeding and crushing at the same time, causing the upper and lower halves of the first crushing assembly 46 to be filled with materials, affecting the material crushing and material screening effects. Similarly, the second crushing assembly 47 is the same as the above operation of the first crushing assembly 46. Thereby improving the screening effect of the material and improving the pre-treatment efficiency of the device for the material.

[0088] The solid waste pretreatment device provided in the embodiment of the present application can be used in scenarios where objects need to be fully crushed, especially the crushing of solid waste in the pretreatment process. It can fully crush the solid waste, reduce the space and cost requirements during storage, transportation and treatment, and for some hazardous wastes or wastes that need to be safely handled, reduce their sharp or large parts, thereby reducing the danger during the treatment process.

[0089] In summary, the embodiments of the present application can fully crush solid waste, eliminating the need for manual sorting of insufficiently crushed solid waste, thereby reducing labor intensity and improving the pretreatment efficiency of solid waste.
