Description

Technical Field

[0001] This utility model relates to the field of dust removal technology in explosives production, specifically a dust removal device. Background Technology

[0002] In the modified ammonium nitrate explosive production line, the conversion of ammonium nitrate from coarse to fine material is mostly carried out by using a roller or cam-type high-efficiency pulverizer. During the production process, a large amount of ammonium nitrate dust is generated, causing pollution to the working environment, harming the health of employees, and corroding workshop buildings and other equipment. Therefore, it is necessary to install dust removal equipment to collect ammonium nitrate dust.

[0003] Currently, existing dust removal devices for explosives production typically employ wet scrubbers or water curtain methods. These methods consume significant amounts of water, and the wastewater is treated at wastewater treatment plants. However, wastewater treatment plants require large areas, have lengthy treatment processes, and the purified wastewater is difficult to recycle in a timely manner. Consequently, the dust removal devices must continuously draw fresh water from external sources to maintain operation, further exacerbating water waste. Therefore, we propose a new dust removal device. Utility Model Content

The filter box is located directly below the dust collector box; the filter box is connected to the filter cartridge through a pipe; the filter box contains a first non-woven fabric layer, a quartz sand layer, and a second non-woven fabric layer in sequence. The water pump has its inlet end connected to the bottom of the filter box via a pipe, and its outlet end connected to the spray pipe via a pipe.

[0015] To make the objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0017] Please see Figures 1-4 This utility model provides a dust removal device, including a dust collection box 1. The lower end and the upper end of the dust collection box 1 are respectively provided with a first conveying pipe 4 and a second conveying pipe 5. The end of the first conveying pipe 4 away from the dust collection box 1 is connected to a high-efficiency pulverizer through a fan, and the end of the second conveying pipe 5 away from the dust collection box 1 is connected to the high-efficiency pulverizer. Under the action of the fan, the powder generated by the high-efficiency pulverizer is sent into the dust collection box 1 through the first conveying pipe 4.

[0018] The dust collector 1 is equipped with a guide plate 6 and a partition plate 7 arranged sequentially from bottom to top. The guide plate 6 serves to evenly distribute the airflow. Several connecting pipes 8 are spaced apart on the partition plate 7, with openings at both ends. The evenly distributed airflow carrying dust enters the space above the partition plate 7 through the connecting pipes 8. A cover plate 9 is fixedly connected to the upper end of the connecting pipes 8 by a fixing rod. A spray pipe 10 is also installed inside the dust collector 1, with nozzles 11 spaced apart on the spray pipe 10. The spray pipe 10 is located in the space above the partition plate 7. When the airflow enters the space above the dust collector 1 through the connecting pipes 8, the water mist sprayed by the nozzles 11 captures suspended dust in the air and promotes its settling, thereby achieving the purpose of dust removal. Because the guide plate 6 can evenly distribute the airflow, the airflow entering the space above the partition plate 7 is more evenly distributed, allowing it to fully contact the water mist sprayed by the nozzles 11, thus achieving a good dust removal effect.

[0019] The side wall of the dust collector 1, located at partition 7, is connected to the upper center of the filter cylinder 3 via a pipe. The filter cylinder 3 contains a filter mesh layer 12, which is made of metal wire mesh. This filter mesh layer 12 is used for preliminary filtration of the water generated after spraying from the dust collector 1, intercepting larger dust and impurities. The filter mesh layer 12 is hollow, and its top and bottom ends are connected to the inner wall of the filter cylinder 3. A valve is installed at the bottom of the filter cylinder 3, and the bottom of the filter cylinder 3 is connected to the filter box 2 via a pipe. When the water after dust removal enters the filter cylinder 3, the filter mesh layer 12 filters the water, and the larger dust and impurities intercepted remain at the bottom of the filter cylinder 3. The filtered water then enters the filter box 2 through the pipe.

[0020] The filter box 2 is located directly below the dust collection box 1; this reduces the floor space occupied by the dust collection device. The filter box 2 contains a first non-woven fabric layer 14, a quartz sand layer 15, and a second non-woven fabric layer 16 arranged sequentially. These layers further filter the water, intercepting tiny particles and ensuring deep purification of the water.

[0021] Furthermore, a water pump 13 is installed at the bottom of the filter box 2. The inlet of the water pump 13 is connected to the bottom of the filter box 2 through a pipe, and the outlet of the water pump 13 is connected to the spray pipe 10 through a pipe. In this way, the water pump 13 can draw the deeply purified water into the spray pipe 10, realizing the recycling of water resources and thus saving water resources.

[0022] To facilitate operation and maintenance of the dust collector 1 and filter box 2, manholes may be optionally provided in the structure of both. These manholes allow for easy access for personnel. Additionally, ladders are installed on the inner walls of both dust collector 1 and filter box 2. When cleaning and maintenance are required, personnel simply open the manholes and climb the ladders to easily and quickly clean and maintain the partition 7, connecting pipe 8, guide plate 6, first non-woven fabric layer 14, quartz sand layer 15, and second non-woven fabric layer 16. The filter box 2 has a support plate 17 installed on its inner wall. A screw is fixedly connected to the support plate 17, and the upper end of the screw passes through the first non-woven fiber fabric layer 14, the quartz sand layer 15, the second non-woven fiber fabric layer 16, and the pressure plate 18 in sequence. Then, a suitable nut is screwed on, and the pressure plate 18 is tightly pressed against the edge of the first non-woven fiber fabric layer 14 by the tightening action of the nut, ensuring that each filter layer is fixed and tightly fitted. When maintenance is required on the first non-woven fiber fabric layer 14, the quartz sand layer 15, and the second non-woven fiber fabric layer 16, the operator can first use tools to remove the nut, and then carefully remove the pressure plate 18. This allows for the sequential replacement and rinsing of the first non-woven fiber fabric layer 14, the quartz sand layer 15, and the second non-woven fiber fabric layer 16, ensuring the filtration effect.

[0023] Optionally, a water supply pipe 19 is provided at the upper end of the filter box 2. The water supply pipe 19 is connected to an external water source and can replenish the required amount of water into the filter box 2 through the water supply pipe 19.
