Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, and more specifically, to a dust removal device for mixing recycled concrete Background Technique

[0002] Recycled concrete refers to the new concrete prepared by crushing, cleaning and grading waste concrete blocks, mixing them in a certain proportion and gradation, partially or completely replacing natural aggregates such as sand and gravel (mainly coarse aggregates), and then adding cement, water, etc. In the production and processing of recycled concrete, it is necessary to mix various ingredients. In order to prevent dust generated during the mixing process from polluting the atmospheric environment, a dust removal device for mixing recycled concrete is mostly used

[0003] The prior art discloses a batching dust removal device for preparing renewable concrete with the application number: CN202023180611.9. When the above utility model is in use, the dust generated during mixing is blocked by the provided cover body, and then the dust in the cover body is dusted by the water mist generated by the atomizing nozzle. Finally, the muddy water generated during the dust removal process is recovered and treated through the recovery bin. However, when workers open the cover body to introduce materials into the feeding port, dust is also easily generated and cannot be dusted in time. At the same time, the muddy water generated during the dust removal process is transferred and treated separately, which not only increases the difficulty of dust removal treatment, but also causes a certain waste of the ingredients of recycled concrete.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a dust removal device for mixing recycled concrete, which has the following

[0016] Advantageous effects:

[0017] (1). The utility model is provided with a mixing cylinder, a cover body and a water storage tank. The support frame is fixedly installed with a mixing cylinder, and a cover body is fixedly installed on the top surface of the mixing cylinder. The top surface of the mixing cylinder is symmetrically installed with feed hoppers, and the top surface of the cover body is symmetrically installed with feed pipes, and the feed pipes are correspondingly located directly above the feed hoppers. A mixing shaft is installed in the center of the mixing cylinder, and a number of mixing rods are uniformly and fixedly installed on the part of the mixing shaft located in the inner cavity of the mixing cylinder. And the bottom end of the mixing shaft is connected to the output end of the servo motor. During use, workers can introduce the ingredients of the recycled concrete material into the feed hopper through the feed pipe, and then into the inner cavity of the mixing cylinder through the feed hopper, which can prevent the dust generated during feeding from escaping to the outside of the cover body. The inner cavity top surface of the cover body is symmetrically installed with mounting shaft frames, and a fan shaft is installed on the mounting shaft frames, and a dust blowing fan blade is fixedly installed at one end of the fan shaft. In addition, a first bevel gear is fixedly installed on the mixing shaft, and a second bevel gear is fixedly installed at one end of the fan shaft, and the second bevel gear meshes with the first bevel gear. Therefore, when the mixing shaft drives the mixing rods to mix and stir the recycled concrete ingredients, it can drive the dust blowing fan blade to rotate, and use the dust blowing fan blade to blow the dust generated during the mixing process into the inner cavity of the cover body to prevent it from escaping outward along the feed pipe. At the same time, workers can start the water pump installed on the water delivery pipe and open the first water valve. At this time, the water pump can be used to introduce the clear water in the water storage tank into the inner cavity of the uniform liquid tank through the water delivery pipe. The top surface of the cover body is symmetrically and fixedly installed with spray trays, and the bottom surface of the spray trays is uniformly connected with atomizing nozzles, and the inner cavity of the spray trays is connected and communicated with the inner cavity of the uniform liquid tank through a connecting pipe. Therefore, the clear water in the uniform liquid tank can be sprayed into the inner cavity of the cover body through the atomizing nozzles, and the sprayed water can be used to perform dust reduction treatment on the dust in the cover body. The generated muddy water can be introduced into the inner cavity of the mixing cylinder through the mud dropping port and remixed with the material introduced into the inner cavity of the mixing cylinder to avoid waste of the recycled concrete ingredients. A connecting rod is symmetrically and fixedly installed on the mixing shaft, and a scraping plate is fixedly installed at one end of the connecting rod. The rotating scraping plate can prevent the muddy water from adhering to the inner wall of the mixing cylinder. Thus, a dust removal device for mixing recycled concrete can introduce the mixing ingredients without opening the cover body, can prevent the generated dust from overflowing, and can make the muddy water generated by dust reduction return to the mixing cylinder for mixing, which not only avoids the separate transfer treatment of the muddy water, but also avoids the waste of the ingredient materials, and has stronger practicability.

[0018] (2) The present utility model is provided with a water delivery pipe and a water injection pipe. As described above, the water delivery pipe can be used to introduce water into the spray tray to achieve the effect of dust reduction and removal. When mixing materials, an appropriate amount of water also needs to be added to the mixing cylinder for mixing the materials. At this time, the worker can open the second water valve installed on the water injection pipe through the control panel. At this time, the clear water in the water storage tank can be introduced into the inner cavity of the mixing cylinder through the three-way pipe and the water injection pipe to be mixed and stirred with the materials. The obtained recycled concrete materials can be exported by opening the discharge valve on the discharge pipe. Therefore, there is no need to install another set of water supply systems for dust removal operations, which is beneficial to reducing the production cost of recycled concrete and has stronger practicability.
