[0002] In the mining machinery industry, the importance of environmental protection and industrial hygiene continues to rise, which has led to a growing demand for efficient and environmentally friendly dust removal systems. However, in the face of existing dust removal technologies, the industry still faces a series of challenges and limitations.

This type of dust collector may have a significant impact on subsequent process flows during use, because the introduction of moisture may lead to a decrease in material quality or process efficiency. In addition, water spray dust removal also has the problem of causing secondary pollution. If wastewater is not properly treated, it may cause further damage to the surrounding environment. Although vacuum dust collectors can provide strong The dust collection capacity and efficiency of the dust collector are high, but the high initial investment cost, large energy consumption and inconvenience in operation often become the focus of user complaints. The maintenance cost of such equipment is also relatively high, and the complex pipe network design sometimes leads to air duct short circuit and dust accumulation problems, which in turn affects the overall dust removal performance. The bag cage and filter bag of the traditional dust collector are installed from top to bottom, which occupies a large space; ordinary filter bags are used, with low filtration accuracy and low wind speed requirements, making it difficult to achieve equipment miniaturization; the ash hopper is used to return the ash, and an ash recovery device needs to be designed separately; there is no independent design of the compartment, the resistance is high, and it is not easy to clean the ash, thus affecting the continuous operation and efficiency of the entire system;

[0003] Existing falling material dust collectors are often unable to handle the splashes generated by falling materials from high altitudes. When heavy materials such as ore fall from high altitudes onto the belt conveyor system, they will bounce due to the impact, causing particulate matter to diffuse into the air, which not only causes material loss, but more importantly, causes significant pollution to the surrounding environment, including deterioration of air quality and potential threats to the health of operators.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Example: See Figure 1-5A nano dust collector specially used for belt blanking dust suppression is shown, comprising a mounting bracket 1, a bag chamber shell 2 is mounted on the outer wall of the mounting bracket 1, a clean air chamber shell 3 is mounted on the outer wall of the bag chamber shell 2, a pulse valve 4 is mounted on the outer wall of the clean air chamber shell 3, one end of the pulse valve 4 is connected to an air bag shell 5, a cylinder 6 is mounted on the outer wall of the bag chamber shell 2, a fan 7 is mounted on the side wall of the bag chamber shell 2, dust collector legs 8 are arranged at the bottom corners of the bag chamber shell 2, a bag cage 9 is arranged on the inner wall of the bag chamber shell 2, and a nano filter bag 10 is arranged on the inner wall of the bag cage 9.

[0023] In this embodiment, specific reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , including a lifting component 11, the lifting component 11 includes a slide block 1101 and a fixing plate 1102, the slide block 1101 is installed on the outer wall of the bag chamber shell 2, the cross section of the slide block 1101 is an L-shaped structure, the inner wall of the slide block 1101 is slidably connected with a sliding enclosure 1103, the sliding enclosure 1103 is located on one side of the bag chamber shell 2, the cross section of the sliding enclosure 1103 is an L-shaped structure, a limiting groove 1104 is provided on the outer wall of the slide block 1101, a connecting block 1105 is installed on the outer wall of the sliding enclosure 1103, the connecting block 1105 is located on one side of the limiting groove 1104, and the inner wall of the connecting block 1105 A threaded rod 1106 is rotatably connected, and a limiting ring 1107 is installed on the outer wall of the threaded rod 1106. Two groups of limiting rings 1107 are provided and are respectively located on the outer wall of the threaded rod 1106. The fixing plate 1102 is installed on the outer wall of the mounting bracket 1. The fixing plate 1102 is located directly below the bag chamber shell 2. A screw lift 1108 is installed on the base surface of the fixing plate 1102. The screw lift 1108 is located between the bag chamber shell 2 and the fixing plate 1102. A controller 1109 is installed on the outer wall of the screw lift 1108. The screw of the screw lift 1108 is connected to the threaded rod 1106 through a connecting piece 1110.

[0024] Among them, the controller 1109 is connected to the screw lift 1108 through a wire and the connection method is electrical connection, so that the device is powered on, the bag cage 9 is located in the inner cavity of the bag chamber shell 2, and the air outlet of the fan 7 and the port of the bag chamber shell 2 are located on the same horizontal plane.

[0025] Among them, one end of the pulse valve 4 passes through the bag chamber shell 2, and the pulse valve 4 is located on one side of the nano filter bag 10, so that the pulse valve 4 allows compressed air to be sprayed and cleaned on the nano filter bag 10 through the nozzle, causing the nano filter bag 10 to expand suddenly. Under the action of the reverse airflow, the dust imparted to the nano filter bag 10 is quickly detached, turning the so-called dust removal work into dust suppression, and the flying dust is solidified and will not fly. The effective dust removal rate is over 95%, and the air volume per unit processing volume of the air collection chamber backblowing and the pulse valve 4 blowing is large, the system resistance is small, and the dust removal efficiency is 99.9%. 2. It can directly handle dust with a dust concentration of 200g / nm³, and the other emission concentrations after treatment are lower than 20g / nm³. It can also meet more stringent requirements according to the special requirements of users.

[0026] When the nano dust collector for dust suppression of belt dropping of this scheme is working, the equipment is directly installed above the outer cover of the belt dropping point, and then the switch of the fan 7 is turned on, so that the dust-containing gas enters the filter chamber from the lower open flange, and the coarser particles directly fall into the inner cavity of the bag chamber shell 2. The dust-containing gas is filtered by the nano filter bag 10, and the dust is retained on the surface of the nano filter bag 10. The clean gas passes through the bag mouth to the clean air chamber shell 3 and is discharged into the atmosphere by the fan 7. When the dust on the surface of the nano filter bag 10 continues to increase, the program controller starts to work and opens the pulse valve 4 one by one, so that the compressed air is sprayed and cleaned through the nozzle to the nano filter bag 10, so that the nano filter bag 10 suddenly expands. Under the action of the reverse airflow, the dust given to the nano filter bag 10 quickly separates from the nano filter bag 10 and falls into the inner cavity of the bag chamber shell 2, wherein the gas containing dust from the belt dropping point is directly sucked into the surface of the nano filter bag 10 by the equipment, and then after filtering the dust, the clean gas is discharged to the outside through the clean air chamber shell 3 and the outlet of the fan 7.

[0027] By converting the dust collector's cloth bag into a more space-saving side-mounted method, it not only reduces the space occupied by the equipment, but also simplifies the installation process and makes maintenance more convenient. In order to meet the specific needs of the site, high-performance nano-scale filter bag materials are selected as filter media, which significantly improves the capture capacity of fine particles such as PM2.5 and PM10. The dust collector abandons the traditional ash hopper structure and makes one end of the fan 7 flush with the port of the bag chamber shell 2, realizing a compact design with an overall height of less than 1 meter, which easily meets the strict space restrictions of on-site installation and allows for chamber bag replacement and maintenance without stopping the machine, greatly improving the continuity and efficiency of dust removal operations, thereby solving the problem of the traditional dust collector bag cage and filter bag being installed from top to bottom, occupying a large space; using ordinary filter bags, the filtration accuracy is low, the wind speed requirement is low, and it is difficult to achieve miniaturization of the equipment; using the ash hopper to return the ash, it is necessary to design an ash recovery device; there is no independent design of the chamber, the resistance is high, and it is not easy to clean the ash, thus affecting the continuous operation and efficiency of the entire system;

[0028] By turning on the switch of the controller 1109, the controller 1109 controls the screw lift 1108 to operate. One end of the screw lift 1108 drives the threaded rod 1106 to rise through the connecting piece 1110, so that the threaded rod 1106 rotates on the inner wall of the connecting block 1105. At the same time, the threaded rod 1106 applies an upward thrust to the connecting block 1105, and the connecting block 1105 drives the sliding enclosure 1103 to rise, so that the sliding enclosure 1103 rises on the inner wall of the slide rail block 1101, thereby causing the slide rail block 1101 to rotate. The dynamic enclosure 1103 shields the periphery of the bag chamber shell 2 to prevent splashing of material falling from the belt, thereby solving the problem that the existing dust collector for falling material is often unable to handle the splashing generated by material falling from a height. When heavy materials such as ore fall from a height onto the belt conveyor system, they will bounce due to the impact, causing particulate matter to diffuse into the air, which not only causes material loss, but more importantly causes significant pollution to the surrounding environment, including deterioration of air quality and potential threats to the health of operators.
