Description

Technical Field

[0001] The utility model belongs to the technical field of concrete dust removal, and particularly relates to an environment-friendly dust removal device for a recycled concrete batching bin. Background Technique

[0002] In the production process of recycled concrete, accurately proportioning key materials such as aggregates, cement, fly ash, etc. and converting them into a uniform dry material mixture is the cornerstone for ensuring product quality and production efficiency. To achieve this goal, the use of an efficient mixer is essential, and complementing it is a carefully designed batching bin system. This system not only ensures that the mixer continuously receives a pre-configured material supply, thus achieving a significant increase in production efficiency of about 30%, but also optimizes the rhythm and coherence of the production process through intelligent material management strategies.

[0003] Given that a large amount of dust is easily generated during the feeding process of concrete raw materials, posing a potential threat to the production environment and the surrounding air quality, the integrated environment-friendly dust removal device on the batching bin is particularly important. However, traditional dust removal solutions are often limited to a single fan negative pressure system and basic dust removal components (such as filters, filter bags, filter elements, etc.). Although such designs can alleviate the dust problem to a certain extent, the efficiency is limited and the maintenance cost is high. As time goes by, the dust removal components are prone to accumulating dust and impurities, resulting in a gradual decline in dust removal performance, shortening the service life of the equipment and making it difficult to continuously provide efficient and stable dust removal effects.

[0004] Therefore, it is very necessary to invent an environment-friendly dust removal device for a recycled concrete batching bin. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides an environment-friendly dust removal device for a recycled concrete batching bin, which includes a dust removal machine case, a dust suction fan, a dust removal filter element, a dust scraper, a dust suction negative plate and a positive electrode rod. The dust suction fan and the dust removal filter element are fixedly installed above the interior of the dust removal machine case, and the dust removal filter element is arranged below the dust suction fan; the dust scraper is fixedly installed on the dust removal machine case; a plurality of dust suction negative plates and positive electrode rods are fixedly installed below the interior of the dust removal machine case, and the positive electrode rod is connected to an electrostatic generator fixedly installed outside the dust removal machine case;

[0006] The dust scraper includes a horizontal top plate, a ball nut, a housing, a ball screw, a servo motor, and a scraper. Both ends of the horizontal top plate penetrate through the dust removal machine box and are fixed to the ball nut. The ball nut is slidably connected to the housing. The ball nut is mounted on the ball screw rotatably installed inside the housing. The housing is fixedly installed on the dust removal machine box. Any end of the ball screw rotatably penetrates through the housing and is fixed to the output end of the servo motor fixedly installed outside it. A plurality of the scrapers are fixedly installed on the horizontal top plate.

[0007] Preferably, a dust suction fan, a dust removal filter element, a dust scraper, and an electrostatic dust removal component are sequentially arranged in the dust removal machine box from top to bottom. The dust suction negative plate and the positive electrode rod are the electrostatic dust removal component. An air flow notch channel is opened at the top of the dust removal machine box.

[0008] Preferably, the dust removal filter element is a filter element assembly composed of a substrate and a plurality of filter elements. The dust removal filter element is located above the horizontal top plate. There is a spacing between the dust removal filter element and the electrostatic dust removal component that allows the horizontal top plate to move horizontally.

[0009] Preferably, a plurality of the scrapers are distributed and arranged below the horizontal top plate. The cross-section of the scraper is triangular. The scraper is in contact with the surface of the dust suction negative plate. The scraper is located between the dust suction negative plate and the positive electrode rod. The positive electrode rod is located between two dust suction negative plates. The spacing between them allows the scraper to move horizontally.

[0011] Compared with the prior art, the present utility model has the following beneficial effects:

[0012] The present utility model integrates the dual advantages of electrostatic dust removal and filter element dust removal, and constructs an efficient and comprehensive dust removal system. By placing the electrostatic dust removal downstream of the filter element dust removal, this design not only gives full play to the high-efficiency capture ability of electrostatic dust removal for tiny particles, but also effectively reduces the burden on the filter element dust removal, significantly shortens the cleaning and maintenance cycle of the filter element, and reduces the operating cost. A dust scraper is equipped on the electrostatic dust removal unit. It can automatically and comprehensively clean the dust and impurities attached to the surface of the electrostatic dust removal after each dust removal operation. The accumulated dust and impurities are effectively scraped off and made to fall back into the storage bin again, realizing the recycling of resources. Description of the Drawings

[0019] As shown in the attached Figure 1 to the attached Figure 3 figure:

[0020] An environment-friendly dust removal device for preparing a recycled concrete silo provided by the utility model comprises a dust removal machine case 1, a dust suction fan 2, a dust removal filter element 3, a dust scraper 4, a dust suction negative electrode plate 5 and a positive electrode rod 6. The dust suction fan 2 and the dust removal filter element 3 are fixedly installed above the interior of the dust removal machine case 1, and the dust removal filter element 3 is arranged below the dust suction fan 2; the dust scraper 4 is fixedly installed on the dust removal machine case 1; a plurality of the dust suction negative electrode plates 5 and the positive electrode rods 6 are fixedly installed below the interior of the dust removal machine case 1, and the positive electrode rod 6 is connected with an electrostatic generator fixedly installed outside the dust removal machine case 1.

[0021] The dust scraper 4 comprises a transverse top plate 41, a ball nut 42, a housing 43, a ball screw 44, a servo motor 45 and a scraper 46. Both ends of the transverse top plate 41 penetrate through the dust removal machine case 1 and are fixed to the ball nut 42. The ball nut 42 is slidably connected with the housing 43. The ball nut 42 is installed on the ball screw 44 rotatably installed inside the housing 43. The housing 43 is fixedly installed on the dust removal machine case 1. Any end of the ball screw 44 rotatably penetrates through the housing 43 and is fixed to the output end of the servo motor 45 fixedly installed outside it; a plurality of the scrapers 46 are fixedly installed on the transverse top plate 41.

[0022] Embodiment 1:

[0023] Specifically, the dust suction fan 2, the dust removal filter element 3, the dust scraper 4 and an electrostatic dust removal assembly are sequentially arranged from top to bottom inside the dust removal machine case 1, and the dust suction negative electrode plate 5 and the positive electrode rod 6 are the electrostatic dust removal assembly; an air flow notch channel is formed at the top of the dust removal machine case 1.

[0024] Specifically, enough space is left between the dust removal filter element 3 and the electrostatic dust removal assembly below it. This design not only ensures the smoothness of air flow but also provides necessary lateral movement space for the transverse top plate 41 and the dust scraper 4 thereon. The electrostatic dust removal assembly is composed of the dust suction negative electrode plate 5 and the positive electrode rod 6. The two work together to adsorb tiny dust particles on the negative electrode plate through electrostatic action to achieve deep dust removal.

[0025] Specifically, the dust scraper 4 is a key component for maintaining the efficient operation of the electrostatic dust removal assembly. It is ingeniously installed inside the dust removal chassis 1 and is connected to the screw linear actuator through the horizontal top plate 41. The screw linear actuator consists of components such as the ball nut 42, the housing 43, the ball screw 44, and the servo motor 45, providing an accurate power source for the dust scraper. The servo motor 45 drives the rotation of the ball screw 44, which in turn drives the ball nut 42 and the horizontal top plate 41 thereon to move horizontally. Below the horizontal top plate 41, several triangular-sectioned scrapers 46 are evenly distributed. These scrapers 46 closely adhere to the surface of the dust suction negative plate 5. As the horizontal top plate moves, they can comprehensively and effectively scrape off the dust and impurities adhering to the negative plate 5. The scraped-off dust falls back into the bin under the action of gravity, realizing the recycling of resources.

[0026] Embodiment 2:

[0027] The device is fixedly installed on the top of the bin. When the device needs to be used, first, using the strong suction of the dust suction fan 2, the dust-containing air in the bin is sucked into the dust removal chassis 1. After passing through the electrostatic dust removal area, an electric field is formed between the dust suction negative plate 5 and the positive electrode rod 6 under the action of the electrostatic generator. Tiny dust particles are electrostatically adsorbed in this electric field, achieving deep dust removal. To ensure the efficient operation of the electrostatic dust removal assembly, a dust scraper 4 is built into the device. It drives the horizontal top plate 41 to move horizontally through a screw linear actuator (consisting of a ball nut 42, a housing 43, a ball screw 44, and a servo motor 45). The scraper 46 closely adheres to the surface of the dust suction negative plate 5, comprehensively scraping off the accumulated dust and impurities. The scraped-off dust naturally falls back into the bin under the action of gravity, realizing the recycling of resources. In terms of the working process, after the device is started, the dust suction fan 2 and the electrostatic generator work synchronously, successively completing steps such as electrostatic dust removal, filter element filtration, dust scraping operation, and dust recovery, forming a circulating dust removal process, and automatically stopping until the preset dust removal effect or running time is reached.

[0028] Using the technical solution of the present utility model, or those skilled in the art being inspired by the technical solution of the present utility model to design a similar technical solution and achieving the above technical effects shall fall within the protection scope of the present utility model.
