Description

Technical Field

[0001] This utility model relates to the field of metal processing waste gas treatment technology, specifically an energy-saving and low-emission wire drawing and peeling fume treatment device. Background Technology

[0002] The wire drawing and shaving process is widely used in metal wire processing. During the process, a large amount of oily fumes, metal particles and volatile organic compounds (VOCs) are generated. Traditional treatment methods mostly use single filtration or direct emission.

[0003] Existing technology draws in external gas through a flue gas inlet pipe. However, during the inhalation process, it is very likely that debris such as dust and leaves will be drawn in, affecting the flue gas purification effect. Furthermore, if debris accumulates in the flue gas inlet pipe for a long time without being cleaned, it will affect normal operation and has certain drawbacks. Utility Model Content

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1-3As shown: An energy-saving and low-emission fume treatment device for wire drawing and shaving includes an upper exhaust pipe 1, an exhaust hood 12, and a lower exhaust pipe 13. The exhaust hood 12 is fixedly installed at the bottom of the upper exhaust pipe 1, and the top of the lower exhaust pipe 13 is located inside the exhaust hood 12 and is fixedly connected to the exhaust hood 12 by several partitions 14. A fixing base 11 is installed on the top of the upper exhaust hood 12, and a telescopic rod 2 is connected to the bottom of the fixing base 11. A fixing mechanism 3 is fixedly installed at the bottom of the telescopic rod 2, and a treatment mechanism 4 is installed at the bottom of the fixing mechanism 3.

[0025] like Figure 2 As shown, a collecting ring plate 131 is installed at the opening of the lower exhaust pipe 13 inside the exhaust hood 12. The diameter of the collecting ring plate 131 gradually decreases into a reverse trumpet shape from the lower exhaust pipe 13 towards the inside of the exhaust hood 12, which can effectively prevent smoke from being discharged from the exhaust hood 12 and prevent particulate matter filtered by the filter from falling into the lower exhaust pipe 13. The partition plate 14 divides the space between the exhaust hood 12 and the lower exhaust pipe 13 into several discharge troughs 15. A waste box 5 is installed on the outside of the lower exhaust pipe 13 below the discharge trough 15. The diameter of the waste box 5 is larger than that of the exhaust hood 12 and is used to collect the processed waste.

[0026] The fixing mechanism 3 includes a fixing frame 31 and a fixing plate 32. The fixing frame 31 is fixedly installed at the bottom of the telescopic rod 2, and the fixing plate 32 is vertically installed between the fixing frame 31 and the first scraper 41, serving as a support and fixing mechanism.

[0027] The processing mechanism 4 consists of a first scraper 41, a second scraper 42, and a connecting column 43. The connecting column 43 is fixedly connected between the first scraper 41 and the second scraper 42. The first scraper 41 is annular, with a dense filter screen 411 installed in the middle. The dense filter screen 411 is used to further filter the flue gas filtered by the sparse filter screen 421. The second scraper 42 is trumpet-shaped, with a sparse filter screen 421 installed at its narrow opening. The sparse filter screen 421 is used to filter large particulate matter. The pore size of the sparse filter screen 421 is larger than that of the dense filter screen 411, and the diameter of the dense filter screen 411 is smaller than that of the sparse filter screen 421. A baffle 412 is also installed at the dense filter screen 411 of the first scraper 41 to ensure that particulate matter does not pass through the dense filter screen 411 when cleaning the inner wall of the upper exhaust pipe 1.

[0028] The fumes generated during the wire drawing and shaving process enter the exhaust hood 12 through the lower exhaust pipe 13. Due to the gathering ring plate 131 preventing the fumes from escaping from the exhaust hood 12, the fumes directly enter the upper exhaust pipe 1. After being filtered by the dense filter screen 411 and the sparse filter screen 421 of the processing mechanism 4, the metal particles and harmful substances in the fumes are effectively filtered. The filtered fumes are discharged through the lower exhaust pipe 13. Part of the filtered waste falls into the waste box 5 through the feeding chute 15, while the other part adheres to the inner wall of the upper exhaust pipe 1. Then, the processing mechanism 4 is moved downward by the telescopic rod 2 to clean the particles attached to the inner wall of the upper exhaust pipe 1, and then the particles fall into the waste box 5 through the feeding chute 15.

[0029] The above-described embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
