Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, specifically a dust collector for a mineral processing workshop. Background Technology

[0002] A large amount of dust is generated during the mineral processing. This dust mainly originates from the crushing, screening, conveying, and loading / unloading of ore. Dust generation not only severely pollutes the working environment of the mineral processing workshop and affects workers' health, but may also cause safety accidents such as explosions. Furthermore, dust emissions damage the surrounding environment and fail to meet environmental protection requirements.

[0003] The prior art discloses a high-efficiency dust collector for workshops, with publication number CN107174906A. It includes a primary filtration device and a secondary filtration device connected in sequence. The primary filtration device includes a first filter tube and a second filter tube. The inner cavity of the first filter tube is provided with a first fan and a first filter screen from right to left. The middle of the second filter tube has a movable coarse filter cylinder. The secondary filtration device includes a storage tank and an adsorbent placed inside the storage tank. Inside the storage tank, from top to bottom, are a second fan, a second filter screen, a spiral filter plate, a bubble-breaking roller, and an exhaust plate. The advantages are: by combining the primary and secondary dust removal devices, it effectively removes large particulate impurities and dust while ensuring gas flow rate and dust removal efficiency; the secondary dust removal device forms fine bubbles from the gas through the exhaust plate, and combined with the bubble-breaking roller, increases the contact time and contact area between the bubbles and the liquid, thereby improving adsorption efficiency.

[0004] The dust collector in the aforementioned mineral processing workshop intercepts large particles of waste while preventing their accumulation on the first filter screen. Combined with the coarse filter cartridge of the second filter tube, it effectively filters large particles of waste, ensuring gas flow rate while collecting them through the movable, insertable coarse filter cartridge. However, the aforementioned device only uses a single-layer filter screen and lacks a multi-layer electrostatic filtration structure composed of alternating filter layers with different polarities. This prevents dust from undergoing multiple electrostatic adsorption processes as it passes through different filter layers, resulting in low filtration efficiency and poor performance during use. Improvements are needed in this regard. Utility Model Content

The U-shaped frame 301 is fixedly connected to both sides of the inner wall of the processing box 1. The positively charged metal wire mesh 302 is connected to the top of the U-shaped frame 301. The intermediate buffer connection end 303 is connected to the bottom of the positively charged metal wire mesh 302. The negatively charged fiber filter layer 304 is connected to the bottom of the intermediate buffer connection end 303. The top of the annular processing cylinder 306 is provided with an air guide hopper. The bottom intermediate buffer connection end 303 is connected to the bottom of the negatively charged fiber filter layer 304. The electrostatic plate 308 is connected to the end of the connecting cylinder 310 away from the inner wall of the annular processing cylinder 306. The annular processing cylinder 306 is fixedly connected to... At the end of the connecting plate 307 furthest from the inner wall of the processing box 1, airflow is guided through an annular electrostatic filtration area via an air guide hopper located at the top of the annular processing cylinder 306. Multiple electrode tubes 309 are arranged within the annular area, forming a uniform electrostatic field in conjunction with the electrostatic plate 308. Dust particles rotate within the annular area under the influence of airflow and are captured by electrostatic adsorption. The connecting cylinder 310 is connected to the inner ring of the annular processing cylinder 306, and the electrode tubes 309 are connected to the surface of the connecting cylinder 310. The positively charged electrode plate 305 is connected to the bottom of the lowest intermediate buffer connecting end 303. The three different processing layers are connected through the intermediate buffer connecting end 303 to ensure the stability of the device and avoid direct contact. The connecting plate 307 is fixedly connected to the inner two sides of the processing box 1, and the end of the connecting plate 307 furthest from the inner two sides of the processing box 1 is fixedly connected to the left and right sides of the annular processing cylinder 306.

[0029] The dust collection device 2 includes a dust collection pump 201, an absorption pipe 202, a telescopic tube end 203, a magnetic insertion end 204, and a magnetic connector 205.
