Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model relates to a wet semi-coke conveying scraper, as shown in figure 1, which comprises a scraper body, wherein the scraper body comprises a machine head 1, a machine tail 2 and a middle box 3 connecting the machine head 1 and the machine tail 2; a feed opening 10 is arranged at the bottom of the machine head 1; a dust collecting port 4 and a feed port 8 are respectively arranged outside the middle box 3, the feed port 8 is close to the tail 2, and the dust collecting port 4 is close to the head 1; and collecting harmful volatile substances in the equipment, and performing centralized treatment.
The outer parts of the machine head 1 and the machine tail 2 are respectively sleeved with a sealing box 4 and a cover plate 5, the top of the sealing shell 4 is circumferentially provided with an annular groove, water is injected into the annular groove, and a water seal is formed between the annular groove and the cover plate 5; two observation windows 9 are arranged on the cover plate 5, a portable plate is arranged on the observation windows 9, and water sealing is carried out between the observation windows 9 and the portable plate;
the device is characterized by further comprising a combustible gas detection device 7 arranged on the outer wall of the middle box 3 and used for detecting the CO concentration in the scraper blade machine, a combustible gas detection hole is formed in the outer side wall of the middle box 3, a probe of the combustible gas detection device penetrates into the middle box 3 through the combustible gas detection hole, a nitrogen protection pipe 6 is further arranged on the outer wall of the middle box 3, one end of the nitrogen protection pipe 6 is led into the middle box 3, the other end of the nitrogen protection pipe 6 is connected with a gas source through a flange, and a control valve is arranged on the nitrogen protection pipe 6 and electrically connected with an alarm of the combustible gas detection device 7; when the concentration of combustible gas in the scraper conveyor exceeds the standard, the control valve is opened in a linkage manner, and nitrogen is injected into the scraper conveyor.
