Description

Technical Field

[0001] This utility model relates to the technical field of dust-gas separation boxes for material guide troughs, specifically a dust-gas separation box for material guide troughs. Background Technology

[0002] In the field of industrial material conveying, especially in the process of guiding powdery and granular materials, traditional material conveying trough equipment generally suffers from problems such as dust overflow and low gas-solid separation efficiency. During material conveying, dust-laden gas is easily generated due to drop impact or airflow disturbance. If directly discharged into the environment, it not only causes air pollution but may also lead to material waste. To solve this problem, existing technologies typically use dust-gas separation devices to filter the dust-laden gas. However, these devices still have the following shortcomings: traditional separation devices mostly use a single fixed baffle structure, making it difficult to dynamically adjust the airflow path according to material characteristics (such as particle size, humidity, and flowability) or changes in operating conditions (such as conveying speed and drop height). This results in some dust not being fully separated and directly entering the discharge box, reducing separation efficiency. Therefore, a material conveying trough dust-gas separation box is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that traditional separation devices mostly use a single fixed baffle structure, which makes it difficult to dynamically adjust the airflow path according to the material characteristics or changes in working conditions, resulting in some dust not being fully separated and directly entering the feeding box, thus reducing the separation efficiency. Therefore, a dust-air separation box with a guide trough is proposed.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the embodiments, by Figure 1-5 A dust-air separation box for a material guide trough is provided, comprising a separation box 1, a material guide pipe 2 connected to the top of the separation box 1, a discharge box 3 connected to the bottom of the separation box 1, a discharge port opened at the bottom of the discharge box 3, an air outlet pipe 4 connected to the rear end of the separation box 1, a pipe cover 5 threadedly connected to the inner side of the air outlet pipe 4, a dust filter screen 6 provided on the inner side of the pipe cover 5, a fixed baffle 7 fixedly connected to the inner side of the separation box 1, and an adjustable baffle 8 provided on the inner side of the separation box 1.

[0023] With the above setup, the dust-laden airflow enters the separation box 1 through the guide pipe 2. The airflow carries material dust (such as ore, coal, etc.). When the airflow encounters the fixed baffle 7, the direction changes abruptly. Large dust particles lose kinetic energy after impacting the fixed baffle 7 due to inertia and settle directly into the discharge box 3. By adjusting the angle of the adjustable baffle 8, it can be made horizontal, blocking the material and causing medium and fine dust particles to gradually settle due to gravity. The preliminarily purified airflow enters the outlet pipe 4. When it passes through the dust filter 6, the clean gas is discharged from the system. Then, the angle of the adjustable baffle 8 is changed again, so that the separated dust and material enter the discharge box 3. Finally, the separated dust and material are discharged through the discharge port at the bottom of the discharge box 3 for centralized recycling or treatment. Compared with the existing technology, the adjustable baffle 8 angle can be adjusted to facilitate sufficient dust settling and enhance separation efficiency.

[0024] Reference Figure 1-5 The adjustable baffle 8 includes a rotating shaft 81. The rotating shaft 81 is rotatably connected to the inner side of the separation box 1. The rotating baffle 82 is fixedly connected to the outer side of the rotating shaft 81. An L-shaped adjusting rod 83 is fixedly connected to the right end of the rotating shaft 81. A limiting seat 84 is fixedly connected to the right end of the separation box 1. An arc-shaped limiting hole 85 is provided on the limiting seat 84. The L-shaped adjusting rod 83 is slidably connected to the inner side of the arc-shaped limiting hole 85.

[0025] With the above structural setup, the operator can manually hold the extended end of the L-shaped adjusting rod 83 and slide it along the arc-shaped limiting hole 85. At this time, the rotating shaft 81 drives the rotating baffle 82 to rotate around the axis (the rotation range is usually designed to be 0°-60°, and the specific angle is determined according to the arc of the limiting hole).

[0026] Reference Figure 1-5The L-shaped adjusting rod 83 is fitted with a rod sleeve 9 on its outer side. An extension piece 10 is fixedly connected to the top of the rod sleeve 9. A first threaded hole 11 is opened on the extension piece 10. A second threaded hole 12 that matches the first threaded hole 11 is opened on the limiting seat 84.

[0027] With the above structural setup, M8 stainless steel bolts (tensile strength ≥ 800 MPa) are used to pass through the first threaded hole 11 and the second threaded hole 12 to form a three-point force structure. The M8 stainless steel bolts provide axial preload to prevent loosening and can limit the rotation baffle 82, keeping the rotation baffle 82 in a horizontal state.

[0028] Reference Figure 1-5 The feeding box 3 is cylindrical, and a feeding shaft 13 is rotatably connected to the inner side of the feeding box 3. Eight partitions 14 are fixedly connected to the outer side of the feeding shaft 13. The eight partitions 14 are equidistantly distributed in a circle. A feeding motor 15 is fixedly connected to the left end of the feeding box 3. The output end of the feeding motor 15 is fixedly connected to the left end of the feeding shaft 13.

[0029] With the above-mentioned structure, the material after dust and gas separation (such as ore powder, coal powder, etc.) falls from the bottom of the separation box 1 into the top inlet of the cylindrical feeding box 3. At this time, the feeding motor 15 drives the feeding shaft 13 to rotate, and the eight circumferentially distributed partitions 14 divide the inside of the feeding box 3 into eight independent chambers to complete the feeding.
