Material mixing device for solid waste resource utilization

Abstract

This utility model relates to the technical field of industrial solid waste mixing devices, providing a material mixing equipment for the resource utilization of solid waste. It includes a drive motor that drives a single shaft, causing the upper crushing blades and the lower stirring rod to rotate synchronously. This achieves integrated and continuous operation of material crushing and mixing processes, significantly reducing the time and energy consumption required for material transfer between different devices in traditional processes. It also lowers manufacturing costs and effectively improves the overall efficiency of solid waste treatment. A second cam block is installed on the shaft, which periodically pushes the first cam block connected to the crushing drum during rotation. The periodic thrust is converted into a composite vibration of the crushing drum in both horizontal and vertical directions by a vibration assembly. This active vibration effectively prevents high-humidity, easily agglomerated solid waste materials from clogging the screen, ensuring smooth material flow after crushing and achieving continuous and uniform feeding, thereby guaranteeing the continuity and stability of production.

Description

Technical Field

[0001] This utility model belongs to the technical field of industrial solid waste mixing devices, and particularly relates to material mixing equipment for the resource utilization of solid waste. Background Technology

[0002] With the accelerating pace of industrialization, the generation of industrial solid waste continues to grow, making its resource utilization a crucial link in achieving a circular economy. Industrial solid waste is diverse, including fly ash, industrial rubber and plastics, smelting slag, and sludge, among others. These materials differ significantly in physical properties such as density, viscosity, and particle size distribution. Transforming solid waste into resource-based products such as roadbed materials and building materials through mixed treatment is an important technological path to achieving the goal of "zero-waste cities." Currently, the resource utilization of industrial solid waste typically involves multiple processes, including crushing, screening, and mixing.

[0003] In existing technologies, these processes are mostly completed by independent equipment. For example, a crusher is first used to pre-crush the solid waste, then screening equipment is used to separate materials that meet the particle size requirements, and finally the materials are sent to a mixing device to be uniformly mixed with other materials. This segmented treatment method is widely used in the field of solid waste resource utilization, but there are a series of technical problems that urgently need to be solved, such as large equipment footprint, complex system configuration leading to high costs, and low efficiency caused by material transfer between processes.

[0004] In view of this, the present invention proposes a material mixing device for the resource utilization of solid waste. Utility Model Content

[0005] This utility model provides a material mixing device for the resource utilization of solid waste, aiming to solve the problems of large footprint, complex system configuration leading to high cost, and low efficiency caused by material transfer between processes in current industrial solid waste mixing equipment.

[0006] This utility model is implemented as follows: a material mixing device for solid waste resource utilization, comprising: Mixing tank; A grinding barrel is disposed on the upper side of the mixing barrel, and a mesh plate is provided at the bottom of the grinding barrel; A vibrating assembly is installed between the mixing tank and the grinding tank; The base plate is located below the mixing tank; Several support columns fixed between the mixing tank and the bottom plate are used to support the mixing tank; A support frame fixed to the top of the base plate; A working component disposed between the mixing tank and the grinding tank; A drive motor is fixedly installed on the top of the support frame. The drive motor drives the working component, which in turn can crush the material inside the crushing barrel and stir the crushed material that falls from the screen into the mixing barrel. The linkage mechanism located on the upper side of the crushing barrel can vibrate and feed material into the crushing barrel during the process of driving the working component through the drive motor.

[0007] Preferably, a movable hole is provided at the center of the top of the crushing barrel and at the center of the mesh plate.

[0008] Preferably, the working component includes a shaft passing through the two movable holes, with stirring rods distributed on the outer wall of the shaft located inside the stirring tank, and crushing blades installed on the outer wall of the shaft located inside the crushing tank.

[0009] Preferably, the working assembly further includes a first limiting disc group and a second limiting disc group, the first limiting disc group being slidably clamped at the top of the crushing barrel, the shaft being slidably clamped at the screen plate, and both the first limiting disc group and the second limiting disc group being fixedly sleeved on the outer wall of the shaft.

[0010] Preferably, the shaft is located at the center of the movable hole, and the inner diameter of the movable hole is larger than the outer diameter of the shaft.

[0011] Preferably, the vibration assembly includes a rocking frame fixed to the outer wall of the crushing barrel, the upper port of the mixing barrel is an inverted cone, a plurality of balls are rotatably disposed at the top of the mixing barrel, and the rocking frame rests on the balls.

[0012] Preferably, the vibration assembly further includes two guide shafts symmetrically arranged on the shaking frame, the guide shafts slidingly passing through the outer wall of the shaking frame, and one end of the guide shaft being fixedly connected to the outer wall of the mixing tank.

[0013] Preferably, a return spring is sleeved on the outer side of each of the two guide shafts, and the two ends of the return spring are respectively connected to the inner wall of the shaking frame and the outer wall of the stirring tank.

[0014] Preferably, the linkage mechanism includes a fixed frame fixed to the top of the crushing barrel, and a first cam block is fixed to the outer wall of the fixed frame.

[0015] Preferably, the linkage mechanism further includes a second cam block fixedly sleeved on the outer wall of the shaft, wherein the second cam block contacts and pushes the first cam block once for each revolution of the shaft.

[0016] Compared with related technologies, the material mixing equipment for solid waste resource utilization provided by this utility model has the following beneficial effects: 1. Integrated Coaxial Linkage Design: A single drive motor drives the same shaft, causing the upper crushing blades and the lower stirring rod to rotate synchronously. This achieves integrated and continuous operation of material crushing and mixing processes, significantly reducing the time and energy consumption required for material transfer between different devices in traditional processes. This not only simplifies the equipment structure and reduces manufacturing costs but also effectively improves the overall efficiency of solid waste treatment.

[0017] 2. Cam-driven active vibration feeding system: A second cam block is installed on the shaft, which periodically pushes the first cam block connected to the crushing barrel during rotation. The periodic thrust is converted into a combined horizontal and vertical vibration of the crushing barrel by the vibration assembly (including a return spring and a guide shaft). Active vibration effectively prevents high-humidity, easily agglomerated solid waste from clogging the screen, ensuring smooth falling of the crushed material and achieving continuous and uniform feeding, thereby guaranteeing the continuity and stability of production.

[0018] 3. Dynamic sealing and flexible connection structure: Movable holes are opened in the center of the top and bottom mesh plates of the crushing barrel, and a first limit plate group and a second limit plate group are configured. The shaft passes through these components, allowing relative displacement between the crushing barrel and the shaft during vibration. While ensuring normal power transmission by the shaft, it effectively adapts to the vibration conditions of the crushing barrel, achieves dynamic sealing, effectively prevents dust from escaping from the moving gaps, and improves the environmental performance and operational reliability of the equipment.

[0019] 4. Compact Spatial Layout and Collaborative Working Mechanism: The crushing tank is directly connected to the upper part of the mixing tank via a shaking frame and ball bearings, forming a compact vertical layout. Vibration, crushing, and mixing functions are highly integrated in space. This greatly saves the equipment's floor space, resulting in a very compact structure. At the same time, it tightly connects the pretreatment (crushing) and core mixing processes, achieving efficient and smooth operation of solid waste treatment from feeding to mixing through the collaborative work of various components.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] Example 1 A preferred embodiment of the material mixing equipment for solid waste resource utilization provided by this utility model is, for example... Figures 1 to 5 The following is a material mixing device for solid waste resource utilization: a mixing tank 2; a crushing tank 5 disposed on the upper side of the mixing tank 2, with a screen plate 501 at the bottom of the crushing tank 5; a base plate 1 disposed below the mixing tank 2; several support columns 3 fixed between the mixing tank 2 and the base plate 1 for supporting the mixing tank 2; a support frame 4 fixed to the top of the base plate 1; a working component 9 disposed between the mixing tank 2 and the crushing tank 5; and a drive motor 7 fixedly installed on the top of the support frame 4, which drives the working component 9, thereby enabling the working component 9 to crush the material inside the crushing tank 5 and to mix the crushed material that falls from the screen plate 501 into the mixing tank 2.

[0025] Specifically, the working assembly 9 includes a shaft 901 passing through the two movable holes 10. Stirring rods 904 are distributed on the outer wall of the shaft 901 located inside the stirring tank 2, and crushing blades 905 are installed on the outer wall of the shaft 901 located inside the crushing tank 5. The working assembly 9 also includes a first limiting disc assembly 902 and a second limiting disc assembly 903. The first limiting disc assembly 902 is slidably clamped at the top of the crushing tank 5, and the shaft 901 is slidably clamped at the mesh plate 501. Both the first limiting disc assembly 902 and the second limiting disc assembly 903 are fixedly sleeved on the outer wall of the shaft 901.

[0026] In this embodiment, during operation, industrial solid waste is thrown into the inside of the crushing barrel 5, the power is turned on, and the drive motor 7 is started. The output shaft on the drive motor 7 drives the shaft 901 to rotate, and the shaft 901 drives the crushing blade 905 and the stirring rod 904 to rotate. The crushing blade 905 pre-crushes the material in the crushing barrel 5, and the crushed material falls into the inside of the stirring barrel 2 through the mesh plate 501 and is stirred and mixed by the stirring rod 904.

[0027] Example 2 Based on Example 1, a preferred embodiment of the material mixing equipment for solid waste resource utilization provided by this utility model is as follows: Figures 1 to 5 As shown: The material mixing equipment for solid waste resource utilization also includes a linkage mechanism 6 installed on the upper side of the crushing drum 5; and a vibration component 8 installed between the mixing drum 2 and the crushing drum 5. During the process of driving the working component 9 by the drive motor 7, the crushing drum 5 can be vibrated and fed through the linkage mechanism 6.

[0028] A movable hole 10 is provided at the center of the top of the crushing barrel 5 and at the center of the screen plate 501. The shaft 901 is located at the center of the movable hole 10, and the inner diameter of the movable hole 10 is larger than the outer diameter of the shaft 901.

[0029] Furthermore, the vibration assembly 8 includes a rocking frame 801 fixed to the outer wall of the grinding barrel 5. The upper end of the mixing barrel 2 is an inverted conical opening, and several ball bearings 804 are rotatably disposed at the top of the mixing barrel 2. The rocking frame 801 rests on the ball bearings 804. The vibration assembly 8 also includes two guide shafts 802 symmetrically arranged on the rocking frame 801. The guide shafts 802 slide through the outer wall of the rocking frame 801, and one end of the guide shaft 802 is fixedly connected to the outer wall of the mixing barrel 2. A return spring 803 is sleeved on the outer side of each of the two guide shafts 802. The two ends of the return spring 803 are respectively connected to the inner wall of the rocking frame 801 and the outer wall of the mixing barrel 2.

[0030] Furthermore, the linkage mechanism 6 includes a fixed frame 601 fixed to the top of the crushing barrel 5, and a first cam block 602 fixed to the outer wall of the fixed frame 601. The linkage mechanism 6 also includes a second cam block 603 fixedly sleeved on the outer wall of the shaft 901. The second cam block 603 can push the first cam block 602 once for each revolution of the shaft 901.

[0031] In this embodiment, during the rotation of the shaft 901, the shaft 901 drives the second cam block 603 to rotate. Each rotation of the second cam block 603 pushes the first cam block 602 once, which in turn pushes the fixed frame 601, allowing the fixed frame 601 to push the crushing barrel 5. The crushing barrel 5 drives the vibration component 8 to slide on the ball bearing 804 sleeved at the top of the mixing barrel 2. The two guide shafts 802 constrain and guide the rocking frame 801. At the same time, the return spring 803 sleeved on the guide shaft 802 can reciprocate and extend, thereby vibrating and feeding the crushing barrel 5.

[0032] In this embodiment, during the shaking of the crushing barrel 5 and the shaking frame 801, the screen plate 501 slides inside the second limiting plate group 903, and the top of the crushing barrel 5 slides inside the first limiting plate group 902. The movable holes 10 opened at the top of the crushing barrel 5 and inside the screen plate 501 can prevent the crushing barrel 5 from interfering with the shaft 901 during the shaking process.
