[0002] Recycled aggregate refers to the aggregate products that meet certain standards obtained by crushing, screening and grading waste concrete, mortar, stone and other building materials during the treatment of construction waste. After the production and processing of aggregate products are completed, they need to be transported and transferred.

[0003] In traditional construction waste treatment and recycled aggregate production, open conveyor belts are a common form of material transfer. Due to its simple structure, low cost and easy maintenance, it is widely used in the transportation process of aggregates. However, this traditional conveying method has a significant disadvantage: during the transfer process, due to the large contact area between the material and the air, a large amount of dust is easily generated. This not only pollutes the working environment and increases the health risks of workers, but also leads to material losses and reduces economic benefits. Therefore, we propose a conveying dust reduction device to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0026] The present application provides a conveying dust reduction device, which is mainly used to solve the problem in the prior art that a large amount of dust is easily generated during the transportation process due to the large contact area between the material and the air. This not only pollutes the working environment and increases the health risks of workers, but also leads to material losses and reduces economic benefits. The following technical solutions are provided:

[0027] A dust removal device, comprising:

[0028] Conveyor belt 1, used for conveying recycled aggregate;

[0029] A dust cover 2 is arranged on the top of the conveyor belt 1, one end of the dust cover 2 is connected to a discharge cylinder 3, and the bottom of one side of the discharge cylinder 3 is connected to a strip discharge hopper 301;

[0030] The quantitative discharging mechanism 4 is arranged in the discharging barrel 3, and is used for quantitatively conveying the recycled aggregate into the strip-shaped discharging hopper 301;

[0031] A feed hopper 201 is connected to the top of the dust cover 2 away from the discharge cylinder 3;

[0032] A dust prevention component 5, arranged at the port of the feed hopper 201, is used to prevent dust from escaping;

[0033] The spray dust reduction assembly 6 is arranged on the top of the dust cover 2, and the spray dust reduction assembly 6 is used for spraying dust removal on the recycled aggregate.

[0034] Workflow Description:

[0035] In the first step, the recycled aggregate is fed into the dust cover 2 from the feed hopper 201 at a uniform speed so that it falls onto the conveyor belt 1 . The dustproof component 5 at the port of the feed hopper 201 can prevent dust from escaping.

[0036] In the second step, the conveyor belt 1 is started to convey the recycled aggregate. In the dust cover 2, the spray dust reduction component 6 sprays the recycled aggregate to remove dust and reduce dust generation.

[0037] In the third step, the recycled aggregate after the spray dust removal treatment enters the discharge barrel 3, and the quantitative discharge mechanism 4 starts to work to quantitatively transport the recycled aggregate to the strip discharge hopper 301. After the transportation is completed, the conveyor belt 1 and the spray dust reduction component 6 are stopped and the equipment is cleaned.

[0038] The conveying dust reduction device is provided with a dust cover 2, a discharge barrel 3 and a spray dust reduction component 6, and a closed transportation system. The dust generated by the recycled aggregate during the transportation process can be effectively sealed inside the system to prevent it from spreading to the working environment, thereby reducing air pollution and potential threats to workers' health. At the same time, since the system is closed, it can reduce material losses caused by dust during the transportation process and improve the efficiency of material use. The spray dust reduction component 6 increases the humidity in the air by spraying water mist into the air, so that the dust particles in the air settle due to the increase in weight, thereby reducing the dust concentration in the air and achieving a more efficient and environmentally friendly dust reduction effect.

[0039] like Figure 4 As shown, in some embodiments, the quantitative discharging mechanism 4 includes a servo motor 401 installed on the top of the discharging barrel 3, the output shaft of the servo motor 401 passes through the top wall of the discharging barrel 3 and is connected to a rotating rod 402, and a ring array on the surface of the rotating rod 402 is fixedly provided with a material-dividing plate 403, and the bottom surface of the material-dividing plate 403 is slidably connected to the bottom wall of the discharging barrel 3. More specifically, since the discharge end of the conveyor belt 1 is connected to the discharging barrel 3, when the recycled aggregate is transported to the end of the conveyor belt 1, the material-dividing plate 403 can push the recycled aggregate to move in the storage barrel, and after one circle of movement, it will fall from the discharging hopper, and the staff can use a collecting device to catch the material. In addition, the number of material-dividing plates 403 is fixed, and the material-dividing plates 403 divide the aggregate entering the discharging barrel 3 into several equal parts. When the recycled aggregate is put into the feed hopper 201 at a uniform speed, the amount of material falling from the strip discharging hopper 301 each time is also the same, and the staff can control the discharging amount by controlling the rotation speed of the servo motor 401 to achieve the effect of quantitative discharging.

[0040] like Figure 4As shown, in some embodiments, the dust-proof component 5 includes a fixed block 501 fixed to the inner wall of the feed hopper 201, a guide rod 502 is obliquely arranged between the bottom side of the fixed block 501 and the other inner wall of the feed hopper 201, a baffle 503 is hingedly connected to the upper side of the feed hopper 201 away from the fixed block 501, a strip hole is constructed on the surface of the baffle 503, and the guide rod 502 is inserted into the strip hole, a spring 504 is connected between the bottom surface of the baffle 503 and the inner wall of the feed hopper 201, and the spring 504 is sleeved on the surface of the guide rod 502, which is more The working principle of the dustproof component 5 is that in the initial state, due to the elastic force of the spring 504, the baffle 503 conflicts with the bottom of the fixed block 501. When the recycled aggregate is loaded into the feed hopper 201, the weight of the aggregate acts on the baffle 503, causing the baffle 503 to rotate around the hinge point, and the recycled aggregate can fall from the gap between the baffle 503 and the fixed block 501. After the recycled aggregate passes through, the spring 504 returns to the initial state, helping the baffle 503 to reset, thereby closing the upper port of the feed hopper 201 and reducing dust escape.

[0041] like Figure 4 As shown, in some embodiments, the fixing block 501 is triangular. More specifically, the slope of the triangle provides a smooth transition path for the aggregate. Under the action of gravity, the aggregate slides down along the slope of the fixing block 501, reducing the impact caused by direct falling and thereby reducing dust.

[0042] like Figure 4 As shown, in some embodiments, the spray dust suppression assembly 6 includes a water tank 601 fixedly mounted on the side of the feed hopper 201, a water pump 602 is installed inside the water tank 601, a guide pipe 603 is fixedly installed on the top of the dust cover 2 and the discharge hopper, the water outlet end of the water pump 602 is connected to one end of the guide pipe 603, and atomizing nozzles are connected at equal intervals on the bottom side of the guide pipe 603, and the atomizing nozzles extend to the interior of the dust cover 2 and the discharge barrel 3. More specifically, the water tank 601 serves as a storage device for a water source, and the water pump 602 is installed inside the water tank 601, for pumping water and delivering it to the guide pipe 603. When the water pump 602 is turned on, it presses water into the guide pipe 603. Atomizing nozzles are installed at equal intervals on the bottom side of the guide tube 603. The function of these nozzles is to convert the water flow into fine water mist. The atomizing nozzles are directed toward the inside of the dust cover 2 and the discharge barrel 3. The released water mist diffuses in the air and comes into contact with the dust-laden air. The water mist particles collide with the dust particles in the air, and the dust particles are weighted down to achieve the purpose of dust reduction.

[0043] like Figure 4As shown, in some embodiments, a section of the guide tube 603 close to the discharge barrel 3 is arc-shaped. More specifically, a section of the guide tube 603 close to the discharge barrel 3 is arc-shaped. The arc-shaped design enables the guide tube 603 to better adapt to the curved shape of the discharge barrel 3 and achieve better spray dust removal effect.

[0044] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
