Description

Technical Field

[0001] The invention relates to the technical field of automatic processing devices for wet-process acetylene carbide slag, and in particular to a closed slag scooping device for generator slag discharge. Background Art

[0002] In industry, acetylene is generally prepared by the reaction of calcium carbide (calcium carbide) and water to produce acetylene gas and calcium hydroxide solution. Since calcium carbide contains non-reactive solid impurities (such as ferrosilicon, coke, etc.), the calcium hydroxide solution produced by the reaction contains more solid impurities, commonly known as calcium carbide slurry.

[0003] In the wet acetylene production process, the treatment of carbide slag slurry not only involves complex process challenges, but also exposes multiple production safety, environmental protection and occupational health risks. The current status of this link is significantly different from the development trend of green and intelligent modern chemical industry, and it is urgent to achieve systematic improvement through technological innovation and management optimization.

[0004] The temperature of carbide slag slurry is as high as 80℃ when it is discharged. Close manual operation can easily cause burns, and high temperature accelerates the volatilization of toxic gases such as residual acetylene gas and hydrogen sulfide and phosphine in the slurry. These gases not only have explosion risks (acetylene explosion limit 2.5%-82%), but the highly toxicity of hydrogen sulfide (H2S) and the spontaneous combustion characteristics of phosphine (PH3) also pose a fatal threat to operators.

[0005] After searching, in the prior art, the Chinese patent application publication number CN117327507A discloses "a wet-process acetylene carbide slag slurry automatic processing system and method, in which the slag discharge port of the acetylene generator extends into the feed end of the horizontal section box of the slag picker; the horizontal section box of the slag picker is provided with an overflow port, the overflow port is connected to the liquid inlet of the stirring tank, the liquid outlet of the stirring tank is connected to the liquid inlet of the acetylene recovery device; the discharge end of the slag picker is connected to the feed inlet of the screening device, and the large particle outlet of the screening device is connected to the waste The receiving bin; the small particle outlet of the screening equipment is connected to the feed port of the jig; the large particle outlet of the jig is connected to the feed port of the first dewatering screen, the small particle outlet of the jig is connected to the feed port of the second dewatering screen, and the discharge port of the second dewatering screen is connected to the second ferrosilicon receiving bin; the water outlet of the first dewatering screen and the water outlet of the second dewatering screen are both connected to the feed port of the slag scavenger. This application solves the problem of certain safety hazards in the prior art of manual slag scavenging of wet acetylene carbide slurry, but the following defects still exist:

[0006] (1) There is a risk of carbide slag clogging during the screening process of the screening equipment, and the higher the water content of the separated carbide slag, the greater the clogging risk, which seriously affects the continuous separation of the carbide slag slurry and is not conducive to ensuring the processing efficiency.

[0067] During operation, the slag discharge port of the acetylene generator is first connected to the feed port of the buried scraper conveyor 10. The temperature of the carbide slag slurry discharged from the slag discharge port of the acetylene generator 1 is about 80°C. At this temperature, the solubility of acetylene in water is the lowest. The closed design can prevent a large amount of acetylene gas from diffusing into the atmosphere to the greatest extent possible, and prevent the irritating odor from polluting the working environment. Then, the acetylene gas in the buried scraper conveyor 10 is sent to the acetylene generator through a recovery pump, and the liquid in the carbide slag slurry enters the recovery box 90 through a filter screen, and can be subsequently sent to the acetylene generator for reuse through a slag pump;

[0068] The carbide slag slurry discharged from the generator moves toward the feed port of the dewatering bucket elevator 20 under the push of the scraper on the buried scraper conveyor 10. After the carbide slag slurry enters the closed dewatering bucket elevator 20, it is transported to the top of the screening mechanism 40 under the lifting of the dewatering bucket. The slurry dropped from the dewatering bucket flows back to the lower inner cavity of the buried scraper conveyor 10 and finally enters the recovery box 90. The drained carbide slag is lifted to a high place and then enters the crushing bucket 310.

The transmission rod 550 rotates and drives the arc guide rail 570 to make an arc reciprocating motion with the connection point of the swing rod 580 and the inverted U-shaped protective shell 320 as the center, thereby driving the arc blocking plate 510 to reciprocately block the crushing bucket 310, thereby realizing the function of the crushing bucket 310 intermittently discharging slag;

[0070] At the same time, the exciting motor 480 is turned on, and the exciting motor 480 drives the support frame 460 to vibrate, and then drives the exciting beam 410 to vibrate, and then drives the main screen 420, the auxiliary screen 430 and the compensation screen 440 to vibrate, so as to achieve the screening of the calcium carbide slag falling on the main screen 420 and the auxiliary screen 430;

[0071] When the swing rod 580 makes a reciprocating motion, the extension plate 520 follows the swing rod 580 to make a reciprocating motion. During the reciprocating swing of the extension plate 520, the limit block 672 slides back and forth in the limit slot 521, thereby realizing the reciprocating lifting and lowering of the lifting rod 671, thereby realizing the reciprocating lifting and lowering of the lifting gear plate 540. When the lifting gear plate 540 rises, the lifting gear plate 540 drives the first fixed gear 610 on the main screen 420 and the main screen 420 connected thereto to rotate counterclockwise along the exciting beam 410, and drives the transmission gear 620 to rotate while the lifting gear plate 540 rises. The first transmission pulley 640 and the first transmission belt 650 drive the driven gear 630 to rotate, and the driven gear 630 drives the second fixed gear 660 to rotate, and finally realizes the angle adjustment function between the main screen 420 and the auxiliary screen 430, so as to realize the inclination of the main screen 420 and the auxiliary screen 430 during the screening process, avoid the incoherent screening caused by the accumulation of calcium carbide slag on the main screen 420 and the auxiliary screen 430, and realize the squeezing of calcium carbide slag between the main screen 420 and the auxiliary screen 430, and the squeezing force helps to break the blockage of the filter hole by calcium carbide slag;

[0072] When the lifting tooth plate 540 descends, the lifting tooth plate 540 drives the first fixed gear 610 on the main screen 420 and the main screen 420 connected thereto to rotate clockwise along the exciting beam 410, and drives the transmission gear 620 to rotate while the lifting tooth plate 540 descends, and then drives the driven gear 630 to rotate through the first transmission pulley 640 and the first transmission belt 650, and drives the second fixed gear 660 to rotate through the driven gear 630, and finally realizes the angle adjustment function between the main screen 420 and the auxiliary screen 430, realizes the switching of the accumulation point of calcium carbide slag, avoids the incoherent screening caused by the accumulation of calcium carbide slag on the main screen 420 and the auxiliary screen 430, and realizes the squeezing of calcium carbide slag between adjacent main screens 420, and its squeezing force helps to break the blockage of the filter hole by calcium carbide slag;

[0073] When the angles of the main screen 420 and the auxiliary screen 430 are changed, the auxiliary screen 430 pulls the compensation screen 440 to slide along the sliding groove 321, and the tension spring 324 realizes the reset of the slider 322, thereby realizing the intermittent compensation of the auxiliary screen 430 and the vertical section of the inverted U-shaped protective shell 320;

[0074] The screened carbide slag enters the slag pool through the discharge plate for recycling and reuse, and the unscreened large particles fall into the circulation box 80, and only the auger conveyor 810 sends them back to the main screen 420 and the auxiliary screen 430 for screening.
