Description

Technical Field

[0001] This utility model relates to the field of dust treatment technology, and in particular to an industrial dust collector with multi-stage settling. Background Technology

[0002] In industrial production processes such as mining, metallurgy, and building materials processing, a large amount of dust is generated. This dust not only pollutes the atmospheric environment but also seriously endangers the health of operators. To control dust pollution, industrial dust collectors have been widely used. Among them, cyclone dust collectors are a common type of equipment. They mainly use the centrifugal force generated by high-speed rotating airflow to separate dust particles in the air.

[0003] However, while this method of relying solely on centrifugal separation has a good separation effect on larger dust particles, its shortcomings in handling fine dust have gradually become apparent as environmental protection requirements have become increasingly stringent. For those extremely small and lightweight dust particles, centrifugal force is insufficient to effectively throw them against the wall of the container, causing these dust particles to be discharged along with the purified airflow, resulting in incomplete dust removal and the purified gas still failing to meet standards.

[0004] Furthermore, existing dust collectors also have structural inconveniences in handling settled dust. Typically, the collected dust is stored in a dust collection box at the bottom of the equipment. When cleaning is required, the entire equipment often needs to be stopped, and operators need to manually open the dust collection box for cleaning or replace the entire box. This process not only interrupts the continuity of production and increases the labor intensity of workers, but also easily generates secondary dust during the cleaning process, polluting the environment again. It is evident that existing industrial dust collectors have urgent needs for improvement in terms of both thorough purification and ease of operation and maintenance.

[0005] Therefore, this utility model proposes an industrial dust collector with multi-stage settling to address the shortcomings of existing technologies. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Example: Please refer to Figures 1 to 4 This utility model provides an industrial dust collector with multi-stage settling, which aims to solve the problems of incomplete purification of fine dust by existing dust collection structures and the complex dust collection and cleaning structure and inconvenient operation.

[0024] like Figure 1As shown, the industrial dust collector with multi-stage settling includes an outer casing 1, and a settling mechanism 2 and a collection mechanism 3 disposed inside the outer casing 1. The collection mechanism 3 is located below the settling mechanism 2. The outer casing 1 provides the mounting base and enclosed shell for the entire device. The settling mechanism 2 is used to perform multi-stage purification treatment on dusty air, and the collection mechanism 3 is used to collect the dust that settles from the settling mechanism 2 and achieve convenient cleaning.

[0025] To solve the above-mentioned technical problems, the technical solution of this embodiment lies in the specific structure and cooperation relationship between the settling mechanism 2 and the receiving mechanism 3.

[0026] Please refer to the following carefully. Figures 1 to 3 The structure of the settling mechanism 2 will be described in detail below: The settling mechanism 2 includes a sealed box 201 for accommodating the dust removal process. The sealed box 201 is fixedly installed inside the outer box 1 by a fixing plate 202. Dust-laden air enters through the dust inlet 4 on the sealed box 201. Inside the sealed box 201, the air first passes through the settling assembly 203. The settling assembly 203 includes a settling box 2031 at the bottom and an inclined plate 2032. The bottom of the settling box 2031 has an ash outlet 2033 for discharging gravity-settled dust. The ash outlet 2033 communicates with the collection mechanism 3 below. The settling airflow is guided into the rotary dust collector 204 by the inclined plate 2032. The bottom of the rotary dust collector 204 is provided with a discharge port 208 for discharging centrifugally settled dust. Its exhaust end is connected to the collection tank 207 through the conduit 205. A spray head 206 is installed inside the collection tank 207 or at the airflow inlet. Finally, the purified gas is discharged through the air outlet 5. This wet purification structure, which is added after centrifugal separation and consists of the conduit 205, the spray head 206 and the collection tank 207, ensures the capture and settling of fine dust in the airflow.

[0027] Please refer to the following carefully. Figure 4 The structure of storage mechanism 3 will be described in detail below: The storage mechanism 3 includes a collection box 301 for containing dry dust. Slide rails 303 are fixed on the inner walls of both sides of the collection box 301. The collection plate 302 is horizontally slidably installed in the collection box 301 via the slide rails 303. A dust outlet 304 is provided on the side wall of the collection box 301. An opening plate 305 is slidably installed on the collection box 301 to close or open the dust outlet 304. In order to realize the quick disassembly and cleaning of the collection box 301, the entire collection box 301 can be pulled out and installed in the outer box 1 via slide rails 306 fixed in the outer box 1. This double sliding structure composed of the collection plate 302 and slide rails 306 realizes the functions of cleaning and dust discharge and quick disassembly and cleaning.

[0028] Based on the above embodiments, the present invention may further include the following preferred technical solutions: Specifically, refer to Figure 2 and Figure 3 The settling assembly 203 includes a settling box 2031 and an inclined plate 2032. An ash outlet 2033 is located at the bottom of the settling box 2031. The upper end of the inclined plate 2032 is near the powder inlet 4, and the lower end is near the inlet of the rotary dust collector 204 to guide airflow. To ensure the stability of the settling mechanism 2 during operation, the settling mechanism 2 also includes a fixing plate 202. The sealed box 201 is fixedly connected to the inside of the outer box 1 via the fixing plate 202. In the wet purification section, a spray head 206 is located inside the collection tank 207 and sprays towards the airflow direction from the duct 205. The collection tank 207 is located in the upstream air path of the air outlet 5 to collect the micro-dust that settles after combining with droplets. Further, referring to… Figure 4 To facilitate the cleaning of dry dust, the collection plate 302 in the storage mechanism 3 is slidably connected to the slide rail 303 installed on the inner wall of the collection box 301 by sliders fixedly connected to both sides of the plate. The opening plate 305 can also be slidably installed on the collection box 301 to selectively cover or expose its dust outlet 304. To facilitate thorough cleaning of the collection box 301, the entire collection box 301 is slidably connected to the slide rail 306 installed on the inner wall of the outer box 1 by sliders fixedly connected to its exterior, so that it can be pulled out of the outer box 1 as a whole.

[0029] Working Principle: When the settling mechanism 2 is activated, dust-laden air enters the sealed box 201 of the main body of the device through the dust inlet hole of the air inlet component 4. The fixing plate of component 202 is a fixed structure to ensure the stability of the sealed box 201 during operation and to avoid the dust removal effect being affected by vibration. After the air enters the sealed box 201, the airflow first passes through the primary separation stage. Due to their greater weight, large dust particles in the air fall into the settling component 203 and cannot continue to flow with the airflow. They naturally settle into the settling box 2031 at the bottom, completing the coarse dust removal. This filters out most of the large dust particles, reducing the load on subsequent purification stages and preventing large particles from clogging subsequent channels. After the dust falls into the settling box 2031, it enters the collection box 301 through the dust outlet hole 2033. The airflow carrying small dust particles enters the rotary dust collector 204 through the inclined plate 2032. The rotary dust collector 204 generates centrifugal force through high-speed rotation. Small dust particles, due to their density being greater than that of air, are thrown towards the inner wall of the rotary dust collector 204 under the action of centrifugal force, and then settle down along the wall into the discharge hole 208 below. However, existing technology often has oversights in this step—some dust particles with extremely small diameters may leave the rotary dust collector 204 with the airflow due to insufficient centrifugal force, resulting in the gas still containing dust after preliminary purification. The airflow after being treated by the rotary dust collector 204 enters the collection tank 207 through the channel duct 205. At this time, the component spray head 206 slowly sprays out a mist of liquid, which can accurately adsorb the tiny dust particles that have not been completely settled in the airflow. After the dust and liquid droplets combine, they settle due to the increase in weight, completely removing residual impurities. Finally, the completely purified gas is discharged through the exhaust port 5 of the exhaust component, ensuring that there is no dust residue in the discharged gas. Furthermore, a collection mechanism 3 is placed at the bottom of the settling mechanism 2. After solid dust enters the collection box 301 through the ash discharge hole, it is stored. When the collection box 301 is full, the dust inside the collection box 301 can be moved towards the ash discharge port 304 by pulling the collection plate 302. To reduce the effort required when cleaning dust, slide rails 1 303 are set on both sides of the collection plate 302 so that the collection plate 302 can be pulled quickly. At this time, the opening plate 305 is pulled to open the ash discharge port 304 so that the fixed dust can be discharged from the collection box 301 through the ash discharge port 304. This achieves dust cleaning without replacing the collection box 301, increasing the efficiency of use. When the collection box needs to be cleaned after a long period of use, the collection box 301 can be pulled out from the outer box 1 by pushing the slide rail 2 306 for quick cleaning, which solves the problem that the machine cannot clean solid dust without stopping.
