Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and in particular to a waste conveying device for the production of autoclaved aerated concrete blocks. Background Technology

[0002] In the production process of autoclaved aerated concrete (AAC) blocks, waste generation is an unavoidable step. If this waste is not properly disposed of, it will not only waste resources but also potentially pollute the environment. Traditional waste disposal methods often suffer from low conveying efficiency, poor processing results, low recycling rates, and inconvenient management. Specifically, waste is easily scattered during transportation, leading to arduous and inefficient cleanup work. Simultaneously, due to inadequate processing equipment, waste often only undergoes coarse crushing, failing to meet the requirements of refined processing, thus affecting its recycling value. Furthermore, the lack of intelligent management methods makes it difficult to achieve the goals of high efficiency and energy conservation in the entire waste disposal process. Utility Model Content

[0003] This utility model relates to a waste conveying device for autoclaved aerated concrete (AAC) block production. By employing a belt conveyor as the core component for waste conveying, combined with a supporting baffle design, it effectively solves the problems of waste scattering and waste during the conveying process, improving conveying efficiency and accuracy. Simultaneously, the processing shaft within the waste treatment tank, along with its crushing and pulverizing wheels, works in tandem to form a highly efficient and precise waste treatment system, significantly improving the waste treatment effect and recycling rate. Furthermore, the mesh-like supporting filter further simplifies the waste treatment process and reduces processing costs. Finally, the application of a control box as an intelligent management tool ensures the stability and reliability of the device's operation, providing a strong guarantee for achieving efficient and energy-saving waste conveying and treatment.

[0004] In a first aspect, this utility model provides a waste conveying device for the production of autoclaved aerated concrete blocks, specifically comprising: a conveying base frame, a belt conveyor, a control box, a waste treatment tank, and a treatment shaft; the conveying base frame is welded from square tubing, and a horizontal belt conveyor is installed at the upper end of the conveying base frame; a waste treatment tank is vertically mounted at the top of one end of the belt conveyor, and the tank walls at both ends of the waste treatment tank are fixedly connected to the housing of the belt conveyor via support arms; a control box is fixedly hung on the outer wall of the housing of the belt conveyor; and a treatment shaft is vertically rotatably installed in the inner cavity of the waste treatment tank.

[0005] Optionally, a support baffle is fixedly installed vertically upward at one end of the belt conveyor near the waste treatment tank. The bottom of the support baffle is tangent to the belt of the belt conveyor, while the upper end of the support baffle is fixedly connected to the outer wall of the waste treatment tank.

[0006] Optionally, the upper end of the waste treatment tank has a narrower opening and a wider bottom, and a waste treatment motor is vertically fixedly installed on the top plate of the upper end of the waste treatment tank. The lower end of the rotating shaft of the waste treatment motor is fixedly connected to the upper end of the treatment shaft.

[0007] The waste treatment tank has a waste inlet pipe vertically connected to the outer wall of the upper constriction section. The waste inlet pipe is a square tube structure, and the outer end of the waste inlet pipe receives the waste generated from the production of autoclaved aerated concrete.

[0008] The lower end of the inner cavity of the waste treatment tank is fixedly installed with a mesh-like support filter screen, and the bottom of the support filter screen is directly opposite the conveyor belt of the belt conveyor.

[0009] Optionally, a crushing wheel is fixedly provided at the lower end of the processing shaft near the support filter screen. The crushing wheel consists of six ring-shaped crushing blades, each of which is a single-edged blade.

[0010] A crushing wheel is fixedly mounted on the processing shaft above the crushing wheel. The crushing wheel is composed of long crushing arms and short crushing arms arranged in a ring at intervals. There are three long crushing arms and three short crushing arms. The ends of the long crushing arms and short crushing arms are equipped with wedge-shaped crushing hammers, and the tips of the crushing hammers are aligned with the cutting edge of the crushing blade.

[0011] This utility model provides a waste conveying device for the production of autoclaved aerated concrete blocks, which has the following beneficial effects:

[0012] First, the device uses a belt conveyor as the core component for waste transportation, ensuring that waste can be continuously and stably transported from the production source to the waste treatment tank. During this process, the support baffles effectively guide the waste to fall accurately into the treatment tank, avoiding waste scattering and waste, and improving transportation efficiency and accuracy.

[0013] Secondly, the processing shaft within the waste treatment tank, along with its crushing and pulverizing wheels, works in tandem to form a highly efficient and precise waste treatment system. The crushing wheel utilizes wedge-shaped hammers to initially crush large pieces of waste, significantly reducing their size and creating favorable conditions for subsequent processing. Meanwhile, the pulverizing wheel uses high-speed rotating blades to finely pulverize the waste, breaking it down into smaller particles for easier recycling or further processing. The co-directional design of the hammers and blades ensures the continuity and efficiency of the crushing and pulverizing process, further enhancing processing efficiency.

[0014] Furthermore, the mesh-like support filter effectively separates crushed waste particles from larger waste residues. Fine particles pass directly onto the conveyor belt through the filter for further processing, while residues remain in the tank for periodic cleaning. This design not only simplifies the waste handling process but also improves waste recycling rates and reduces processing costs.

[0015] Finally, the control box, acting as the central nervous system of the device, monitors and adjusts its operating status in real time, ensuring that parameters such as conveying speed and processing shaft speed are always kept within the optimal operating range. This intelligent management method not only improves the operational stability and reliability of the device but also provides a strong guarantee for achieving efficient and energy-saving waste conveying and processing.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Example 1: Please refer to Figures 1 to 4 :

[0031] This utility model proposes a waste conveying device for autoclaved aerated concrete (AAC) block production, comprising: a conveying base frame 1, a belt conveyor 2, a control box 3, a waste treatment tank 4, and a processing shaft 5; the conveying base frame 1 is made of welded square tubing, and a horizontal belt conveyor 2 is installed at the upper end of the conveying base frame 1; a waste treatment tank 4 is vertically mounted on the top of one end of the belt conveyor 2, and the tank walls at both ends of the waste treatment tank 4 are fixedly connected to the shell of the belt conveyor 2 via support arms 401; the control box 3 is fixedly hung on the outer wall of the shell of the belt conveyor 2; the processing shaft 5 is vertically rotatably installed in the inner cavity of the waste treatment tank 4, and the conveying base frame 1, made of welded square tubing, stably supports the entire device, while the belt conveyor 2 installed at its upper end operates horizontally, responsible for continuously conveying the waste generated during the autoclaved aerated concrete production process from the source to the vicinity of the waste treatment tank 4.

[0032] Among them, a support baffle 201 is fixedly installed vertically upward at one end of the belt conveyor 2 near the waste treatment tank 4. The bottom of the support baffle 201 is tangent to the belt of the belt conveyor 2, while the upper end of the support baffle 201 is fixedly connected to the outer wall of the waste treatment tank 4. This design cleverly guides the waste to the entrance of the waste treatment tank 4, effectively preventing the waste from scattering and shifting during the conveying process.

[0033] Among them, the upper end of the waste treatment tank 4 has a narrow top and wide bottom opening structure, which not only facilitates the centralized treatment of waste, but also optimizes the utilization of internal space. The waste treatment motor 402 is vertically fixedly installed on the top plate of the upper end of the waste treatment tank 4, and the lower end of the rotating shaft of the waste treatment motor 402 is fixedly connected to the upper end of the treatment shaft 5.

[0034] Waste inlet pipe 403 is vertically connected to the outer wall of the upper end of the waste treatment tank 4. Waste inlet pipe 403 is a square tube structure. The outer end of waste inlet pipe 403 receives the waste generated by autoclaved aerated concrete production and connects to the waste outlet of autoclaved aerated concrete production line to ensure that the waste can flow smoothly into the treatment system.

[0035] A mesh-like support filter 404 is fixedly installed at the lower end of the inner cavity of the waste treatment tank 4. The support filter 404 is directly opposite the conveyor belt of the belt conveyor 2. The crushed waste particles are screened through the mesh-like support filter 404 at the lower end of the inner cavity of the waste treatment tank 4. Fine particles pass smoothly through the filter and fall directly onto the conveyor belt of the belt conveyor 2, where they are transported to a designated location for further processing or recycling. Larger waste residues that cannot pass through the filter remain in the tank, awaiting periodic cleaning.

[0036] In Example 2, based on Example 1, a crushing wheel 502 is fixedly provided at the lower end of the processing shaft 5 near the support filter screen 404. The crushing wheel 502 consists of six-bladed ring-shaped crushing blades 5021, and each crushing blade 5021 is a single-edged blade.

[0037] A crushing wheel 501 is fixedly mounted on the processing shaft 5 above the crushing wheel 502. The crushing wheel 501 consists of long crushing arms 5011 and short crushing arms 5012 arranged in a ring at intervals. There are three long crushing arms 5011 and three short crushing arms 5012. The ends of the long crushing arms 5011 and the short crushing arms 5012 are equipped with wedge-shaped crushing hammers. The tips of the crushing hammers are aligned with the cutting edge of the crushing blade 5021. The long crushing arms 5011 and the short crushing arms 5012 are arranged alternately. The wedge-shaped crushing hammers at the ends crush large pieces of waste into smaller fragments with a strong impact force, which not only improves the crushing efficiency but also ensures the uniformity of the crushing effect. Subsequently, the waste that has undergone preliminary crushing continues to move downward to the crushing wheel 502. Driven by high-speed rotation, the crushing blade 5021 finely crushes the waste, refining it into smaller particles to meet the requirements of subsequent recycling or processing.

[0038] The working principle of this embodiment:

[0039] When the device is started, the belt conveyor 2 starts first, driving its belt to run continuously, transporting the waste from the autoclaved aerated concrete production process from the source to the vicinity of the waste treatment tank 4. To ensure that the waste can be smoothly transferred from the belt conveyor 2 to the waste treatment tank 4, a support baffle 201 is specially provided at the end of the belt conveyor 2 near the waste treatment tank 4. The bottom of the baffle is tangent to the belt, and the top is fixedly connected to the outer wall of the waste treatment tank 4, thereby guiding the waste to fall accurately into the tank.

[0040] After the waste enters the waste treatment tank 4, the treatment shaft 5 is driven to rotate by the waste treatment motor 402. The crushing wheel 501 on the treatment shaft 5 first contacts the waste, and the wedge-shaped crushing hammers installed on its long crushing arm 5011 and short crushing arm 5012 perform preliminary crushing of large pieces of waste. The size of the waste is reduced by impact, and the tip design of the crushing hammer makes the crushing effect more significant, laying the foundation for subsequent processing.

[0041] As the processing shaft 5 continues to rotate, the initially crushed waste is further conveyed to the crushing wheel 502. The crushing wheel 502 consists of six ring-shaped crushing blades 5021. These single-edged blades rotate at high speed to finely crush the waste into smaller particles. During the crushing process, the cutting surfaces of the crushing blades 5021 are designed to face the same direction as the tip of the breaker hammer, ensuring a smooth and continuous crushing process and improving processing efficiency.

[0042] The crushed waste particles then pass through the mesh-like support filter 404 at the lower end of the inner cavity of the waste treatment tank 4. Since the support filter 404 is directly above the conveyor belt of the belt conveyor 2, the fine particles fall directly onto the conveyor belt under gravity and are then transported by the belt conveyor 2 to a designated location for recycling or further processing. Larger waste residues that cannot pass through the filter remain in the waste treatment tank 4, awaiting periodic cleaning.

[0043] Throughout the process, control box 3 is responsible for monitoring and adjusting the operating status of the device to ensure that parameters such as conveying speed and processing shaft speed are kept within the optimal working range, so as to achieve efficient and stable waste conveying and processing.
