Description

Technical Field

[0001] This utility model relates to the field of slag removal and dust suppression technology in earthwork engineering, specifically a slag removal and dust suppression device for earthwork engineering. Background Technology

[0002] In civil engineering, earthwork is a fundamental and important construction activity, including site leveling, excavation of foundation pits and trenches, roadbed excavation, excavation of civil defense works, ground filling, roadbed construction, and foundation pit backfilling. During the construction of these projects, a large amount of soil debris, gravel, and dust are often generated. This soil debris and dust not only pollute the construction site environment, affecting construction hygiene and the health and safety of workers, but also damage the surrounding ecological environment. This does not meet the requirements of modern construction for green, environmentally friendly, and sustainable development, and therefore dust suppression devices are needed.

[0003] According to the patent application CN221890350 U, "A dust removal and slag reduction device for earthwork engineering is described as follows: "A dust removal and slag reduction device for earthwork engineering includes a frame; a vibrating screen, which is installed on the frame and is equipped with a slag discharge pipe and a soil discharge pipe; a collection box, which is installed below the soil discharge pipe and is used to collect soil; a negative pressure box, which is installed on one side of the frame and is equipped with a negative pressure fan at the top; the suction port of the negative pressure fan is equipped with a suction pipe connected to the top of one side of the negative pressure box."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In the process of using this utility model, earth and stone are fed into a vibrating screen, which separates the gravel and soil through vibration. The gravel is discharged from the vibrating screen through the slag discharge pipe, while the soil falls into the collection box through the soil discharge pipe. A negative pressure fan creates negative pressure in the negative pressure box, causing the dust in the vibrating screen to be drawn into the negative pressure box through the negative pressure pipe and fall into the negative pressure box. The negative pressure pipe is connected to the top of the vibrating screen and the top of the slag discharge pipe to better absorb the dust. However, in actual use, this device only separates gravel and soil through the vibrating screen. During the screening process, some soil clumps, preventing some of it from falling through the mesh of the vibrating screen into the bottom collection box for collection. This results in poor screening effect of gravel and soil, reducing the overall working efficiency of the device. Therefore, it is necessary to improve the dust removal and slag reduction device for earthwork projects. Utility Model Content

[0016] Compared with the prior art, this utility model provides a slag removal and dust suppression device for earthwork engineering, which has the following beneficial effects:

[0017] 1. This dust removal and slag reduction device for earthwork projects utilizes a vibrating crushing mechanism. Starting motor one causes it to rotate continuously, vibrating the entire screening box. As the crushed stone and soil move along the pressure plate, starting motor two, with the assistance of spring two, causes the pressure column to simultaneously strike the crushed stone and soil downwards. Simultaneously, the right pressure column moves upwards. As the rotating rod continues to rotate, it reciprocates, causing the left and right pressure columns to strike the crushed stone and soil downwards in sequence. This continuous striking and crushing process breaks up any clumps in the soil, preventing further clogging and improving the screening effect of the crushed stone and soil, thus enhancing the overall working efficiency of the device.

[0018] 2. The dust removal and suppression device for earthwork projects uses a dust suppression mechanism to start a negative pressure fan. The negative pressure fan draws the dust from the screening box and the slag removal pipe into the outer dust box through the connecting hose. At the same time, an external water source is connected so that the dust suppression water enters the spray pipe through the water inlet pipe and is sprayed out through the spray pipe, thereby making the dust suppression water and dust fully combine and preventing the dust from scattering.

[0037] Example 2:

[0038] Based on the existing technology's need to address the dust handling issues during the slag removal process, please refer to [link / reference]. Figure 6 Furthermore, in conjunction with Embodiment 1, the dust suppression mechanism 5 includes a dust suppression box 51, which is fixedly connected to the back of the collection box 1. A filter plate 52 is fixedly connected to the inner wall of the right side of the dust suppression box 51. A negative pressure fan 53 is fixedly connected to the right side of the dust suppression box 51. A water inlet pipe 54 is fixedly connected to the back of the dust suppression box 51. A spray pipe 56 is fixedly connected to the front of the water inlet pipe 54. A connecting hose 55 is fixedly connected to the top of the dust suppression box 51, which facilitates dust suppression during the screening process.

[0039] Furthermore, the spray pipe 56 is fixedly connected inside the dust settling box 51, and the end of the connecting hose 55 away from the dust settling box 51 is fixedly connected to the slag discharge pipe 6 and the back of the screening box 414 respectively, so as to facilitate the uniform spraying of dust settling water.

[0040] In actual operation, when the device is used, the slag and gravel generated from the earthwork project are first put into the screening box 414. The vibrating crushing mechanism 4 is activated, and motor 415 is started. Motor 415 drives the counterweight 416 to rotate, causing the entire screening box 414 to vibrate. The slag and gravel falling into the screening box 414 move downwards due to gravity. As the slag and gravel move along the pressure plate 4212, motor 422 is activated, driving the rotating rod 423 to rotate. The rotating rod 423 then drives the connecting frame 424 downwards. Simultaneously, the connecting frame 424 drives the left pressure rod 425 downwards, which in turn drives the corresponding clamping frame 428 downwards. The clamping frame 428 then drives the lower pressure column 4210 downwards. With the cooperation of spring 429, the pressure column 4210 simultaneously strikes the slag and gravel downwards. At the same time, the right pressure column 4210... 210 moves upward, and as the rotating rod 423 continues to rotate, it reciprocates to drive the left and right pressure columns 4210 to knock down the crushed stone and soil in sequence. During the continuous knocking and hammering, the lumpy soil is broken up. After processing, it falls onto the screen plate 413 set inside the screening box 414 for screening. During the continuous vibration screening, the soil falls through the screen plate 413 into the bottom collection box 1 for collection, while the crushed stone moves to the left during continuous vibration and is discharged outside the device through the slag pipe 6. At the same time, during the vibration screening, the dust suppression mechanism 5 starts the negative pressure fan 53, which draws the dust inside the screening box 414 and the slag removal pipe into the outer dust box through the connecting hose 55. At the same time, an external water source is connected, and the dust suppression water enters the spray pipe 56 through the water inlet pipe 54 and is sprayed out through the spray pipe 56, so that the dust suppression water and dust are fully combined.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
