Description

Technical Field

[0001] The invention relates to the technical field of waste treatment of concrete slabs, and in particular to a waste treatment device of an autoclaved aerated concrete slab production line. Background Art

[0002] As a new type of energy-saving and environmentally friendly wall material, autoclaved aerated concrete board has the characteristics of convenient construction, low comprehensive cost, environmental protection, good thermal insulation, fire prevention, heat insulation, earthquake resistance and sound insulation. However, waste is inevitably generated in the production process. If these wastes are not handled properly, they will not only waste resources, but also pollute the environment.

[0003] A large amount of waste is generated during the production process of autoclaved aerated concrete slabs, and traditional waste treatment methods have problems such as serious environmental pollution and low resource utilization. The existing crushing device is mainly used to crush the waste, but it cannot make effective improvements to the defects of large dust generation and low treatment efficiency. The current metal recycling process mainly relies on manual sorting, which has the disadvantages of low efficiency, high cost, and difficulty in collection. In addition, the existing waste treatment devices generally adopt a single crushing method, lack of classification processing of particle size, and directly reuse the crushed waste, which will lead to uneven material properties in the subsequent production process, affecting product quality. At the same time, the waste is not effectively heated, resulting in low process efficiency and low thermal energy utilization.

[0004] Therefore, there is an urgent need for a device that can effectively treat autoclaved aerated concrete board waste, reduce environmental pollution, and improve resource utilization. Summary of the invention

A mixing box is also provided on the right side of the processing box, and the right side of the conveying rack extends to the left side of the mixing box.

A unloading chute is arranged on the right side of the fixed collection frame, and a movable collection frame is movably arranged inside the fixed collection frame.

[0013] Furthermore, two mixing racks are rotatably arranged inside the mixing box, and a driving motor for driving one of the mixing racks is arranged on the top of the mixing box.

[0015] Furthermore, the working method of the waste treatment device of the autoclaved aerated concrete board production line comprises the following steps:

[0016] When the waste material of the autoclaved aerated concrete board production line is processed, the waste material is fed into the feed box, and then the two dust cover plates between the two mounting frames are controlled to be closed, and the dust generated during the crushing process of the waste material is sucked through the several dust suction ports at the bottom of the two dust cover plates;

[0017] The output shaft of the servo motor controls one of the crushing rollers to rotate, and two mutually meshing transmission gears are used to make the two crushing rollers rotate relatively inside the blanking rack, so as to continuously crush the waste inside the feed box;

[0018] After the waste is crushed by two crushing rollers, the crushed materials fall on the top of the filter frame, and the crushed materials are sorted by the screening net inside the filter frame, so that the crushed materials with a particle size smaller than the screen mesh holes fall into the inside of the processing box, and the crushed materials with a particle size larger than the screen mesh holes remain above the screen mesh, and the scraper plate between the two scraper frames is used to scrape the crushed materials above the screen mesh left and right;

[0019] After the crushed materials are screened by the screening net, the scraper plate is used to scrape the crushed materials left on the screen net to the inside of the fixed frames on both sides, and the crushed materials that do not meet the screening particle size requirements are sent to the return channel inside the fixed frames on both sides. The crushed materials in the return channel are sent out through the circulating discharge port by using a plurality of feeding plates arranged on the surface of the conveyor belt, and the returned crushed materials are further crushed by two crushing rollers;

[0020] After the waste materials are crushed and screened inside the blanking rack, the crushed materials with uniform particle size are transported to the inside of the mixing box through the conveying rack. Before the crushed materials enter the mixing box, the crushed materials on the conveying rack are first dispersed by the material distribution rack, and then the metal materials mixed in the crushed materials are adsorbed by the magnetic suction sleeves arranged on the second surface of the conveyor belt, and then the metal materials adsorbed on the second surface of the conveyor belt are automatically collected by the right side of the fixed collecting frame. The collected metal materials fall into the inside of the movable collecting frame. A pressure sensor is arranged at the bottom of the inner wall of the movable collecting frame. When the metal materials in the movable collecting frame are collected to a certain weight, the movable collecting frame is pulled out from the inside of the fixed collecting frame.

[0021] After the crushed material is recycled by the metal recycling component, it is sent into the mixing box through the conveyor rack, and then other auxiliary materials and water are sent into the mixing box. The two mixing racks are controlled to rotate in different directions inside the mixing box, and the crushed material of the waste is prepared into slurry inside the mixing box. The heat energy of the autoclaved aerated concrete board production line is used to heat the slurry inside the mixing box through the spiral heat exchange tube.

[0022] The beneficial effects achieved by the present invention using the above structure are as follows:

[0023] 1. The present invention realizes multiple steps such as dust control, waste material crushing, screening and sorting, metal separation and recovery, and slurry preparation in the comprehensive treatment process by setting up key links such as the blanking rack, crushing assembly, material dividing assembly, metal recovery assembly and mixing box, which significantly improves the sustainability of the process and the efficiency of resource utilization, realizes the optimization of the whole process from dust control to material processing, significantly enhances the environmental protection performance and resource utilization efficiency of the production line, and is of great significance for improving production sustainability and economic benefits.

[0024] 2. In the present invention, waste materials are sent to the feed box for preliminary collection, and the set slope is designed to provide a natural falling path for dust, thereby reducing the flying of dust. The opening and closing of the dust cover realizes the real-time absorption of dust, thereby reducing environmental pollution. This design ensures that the impact of the device on the surrounding environment is minimized during operation.

[0025] 3. The crushing assembly of the present invention adopts a double crushing roller design driven by a servo motor, which not only simplifies the transmission chain and reduces maintenance costs, but also realizes continuous and efficient waste crushing processing, improves the contact and crushing effect between materials, and ensures the uniformity and fineness of the crushed material.

[0026] 4. The screening net in the material separation component of the present invention can accurately identify crushed materials of different sizes, and the left and right scraping of the scraper plate improves the screening efficiency, ensuring the accuracy of material classification. The design of the return channel supplements the omission of any particle size in the crushing process. Through the cyclic crushing, the materials that do not meet the screening requirements are processed for the second time, ensuring the uniformity of the final waste particles and the particle size range that meets the requirements of the production line.

[0027] 5. The metal recovery component of the present invention uses magnetic suction technology to directly separate the metals mixed in the crushed materials, reducing the complexity and cost of subsequent processing. The automatic collection device simplifies the collection and processing process of metal materials and realizes efficient management and reuse of materials. Finally, the double mixing racks set in the mixing box cooperate with the drive motor to realize the mixing of materials in different directions. Combined with the heat energy transmission of the spiral heat exchange tube, it not only improves the efficiency of slurry preparation, but also effectively utilizes the waste heat in the production process. This design not only reduces energy consumption, but also maximizes the overall operating efficiency of the production line and the level of resource recycling. BRIEF DESCRIPTION OF THE DRAWINGS
