[0002] A slag scraper for a gasifier is a mechanical slag discharging device used under a gasifier; the existing slag scraper for a gasifier is a scraper type slag scraper, and continuously running scraper chains are used to continuously transport the cold-quenched furnace slag immersed in water to the slag discharge port, thus completing the slag removal process. When the existing scraper type slag scraper operates, in order to prevent the leakage of harmful gases, the slag scraper is simply sealed.

[0011] Preferably, a number of filter holes are provided on the slag-removing movable filter plate, and a slag inlet is provided on the top surface of the horizontal chassis.

[0012] A method for pumping and discharging harmful gases, which uses the above-mentioned gasifier slag-removing machine, includes the following steps; When the slag enters the horizontal chassis, it falls onto the horizontal section of the slag-removing movable filter plate. The slag-removing movable filter plate rotates, and the fixed scraping block and the rotating filter plate drive part of the slag to move. When the positions of the fixed scraping block and the rotating filter plate move to the inclined rising section of the slag-removing movable filter plate, the rotating filter plate rotates, so that the slag-removing movable filter plate, the rotating filter plate, the installation filter plate and the fixed scraping block form an irregular box-shaped container. At this time, the slag-removing movable filter plate stops rotating, the rotating water-squeezing plate rotates and drives the water-squeezing block to move towards the rotating filter plate, and water squeezing work is carried out on the slag located in the irregular box-shaped container; After the water squeezing is completed, the air extraction partition plate moves into the inclined rising chassis, so that the inclined rising chassis is hermetically isolated from the horizontal chassis, the air inlet and the air extraction port are opened, the air inlet intakes air, the air extraction port extracts air, so that the harmful gases in the inclined rising chassis are all extracted. After the air extraction is completed, the collection box is opened, the slag in the collection box is discharged, the collection box is closed, the air inlet and the air outlet are closed, the movable air extraction partition plate is moved out of the slag-removing chassis, and the slag-removing movable filter plate rotates to transfer the water-squeezed slag into the collection box.

[0013] Compared with the prior art, the present invention provides a gasifier slag-removing machine and a method for pumping and discharging harmful gases, which have the following beneficial effects: 1. When the slag enters the horizontal chassis, it falls onto the horizontal section of the slag-removing movable filter plate. The slag-removing movable filter plate rotates, and the fixed scraping block and the rotating filter plate drive part of the slag to move. When the positions of the fixed scraping block and the rotating filter plate move to the inclined rising section of the slag-removing movable filter plate, the rotating filter plate rotates, so that the rotating filter plate, the rotating installation plate and the fixed scraping block form an irregular box-shaped container. At this time, the slag-removing movable filter plate stops rotating, the rotating water-squeezing plate rotates and drives the water-squeezing block to move towards the rotating filter plate, and water squeezing work is carried out on the slag located in the irregular box-shaped container. The irregular box-shaped container can better carry out water squeezing work on the slag. When squeezing water, the slag cannot move out of the box-shaped container, and the slag water in the slag can be fully squeezed out, preventing harmful gases dissolved in the water from being discharged from the slag-removing chassis together with the slag, polluting the working environment and endangering the health of the staff.

[0014] 2. After the water squeezing is completed, the air extraction partition plate moves into the inclined lifting chassis, sealing off the inclined lifting chassis from the horizontal chassis. The air inlet pipe and the air extraction pipe are opened. The air inlet pipe admits air, and the air extraction pipe extracts air, so that all the harmful gases in the inclined lifting chassis are extracted. After the air extraction is completed, the collection box is opened, and the slag in the collection box is discharged. The collection box is closed, the air inlet pipe and the air outlet pipe are closed, and the movable air extraction partition plate is moved out of the slag skimming chassis. The slag skimming movable filter plate rotates to transfer the slag after water squeezing into the collection box; when discharging the slag, the inclined lifting chassis is separated from the horizontal chassis, and the inclined lifting chassis is evacuated. After the evacuation of the inclined lifting chassis is completed, the slag is discharged to prevent the leakage of harmful gases during slag discharge, resulting in a reduction in the air extraction and discharge effect.

[0015] 3. The limit slider limits the air inlet sealing block. The partition connecting plate drives the movable push plate to move. When the movable air extraction partition plate moves into the slag skimming chassis and is sealed, the movable push plate pushes the limit slider into the limit installation groove. At this time, the limit of the air inlet sealing block by the limit slider is released. When the air inlet sealing block moves upward to open the air inlet, the air inlet sealing block limits the movable push plate. When the horizontal chassis and the inclined lifting chassis are not completely separated, the air inlet and the air extraction port cannot be opened. When the air inlet and the air extraction port are completely closed, the horizontal chassis and the inclined lifting chassis cannot be separated, preventing the leakage of harmful gases.

[0016] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

When the moving air extraction partition 303 moves to the slag fishing chassis 1 to complete the seal, the moving push plate 320 pushes the limit slider 319 into the limit mounting groove. At this time, the limit slider 319 releases the limit on the air intake sealing block 312. When the air intake sealing block 312 moves upward to open the air intake, the air intake sealing block 312 limits the moving push plate 320. When the horizontal chassis 102 and the inclined lifting chassis 101 are not completely separated, the air intake and the air extraction ports cannot be opened. When the air intake and the air extraction ports are completely closed, the horizontal chassis 102 and the inclined lifting chassis 101 cannot be separated, preventing harmful gas leakage.

[0028] Please refer to Figure 1 - Figure 12, the air extraction assembly 3 further includes a collection moving plate 321 and a collection cylinder 322. A slag discharge port is opened at the top end of the bottom surface of the inclined rising chassis 101. The collection box 304 is fixedly installed at the slag discharge port. A moving installation notch is opened on the side of the collection box 304. The collection moving plate 321 is slidably installed at the moving installation notch. The collection cylinder 322 is fixedly installed at one end of the collection box 304. The output end of the collection cylinder 322 is fixedly connected to the collection moving plate 321; During use, the collection cylinder 322 drives the collection moving plate 321 to move, enabling the collection box to open and discharge slag.

[0029] Please refer to Figure 1 - Figure 12 , a driving motor 104 is fixedly installed outside the horizontal chassis 102. Transmission chains are fixedly connected to both sides of the slag fishing moving filter plate 201. The driving shaft of the driving motor 104 passes through the horizontal chassis 102 and the sealing partition 103 and is fixedly connected to the driving gear of the transmission chain; During use, the driving motor 104 drives the driving gear of the transmission chain to rotate. The driving gear drives the transmission chain to rotate. The rotation of the transmission chain drives the slag fishing moving filter plate 201 to rotate.

[0030] Please refer to Figure 1 - Figure 12 , a number of filter holes are opened on the slag fishing moving filter plate 201. A slag inlet is opened on the top surface of the horizontal chassis 102; During use, the furnace slag enters the horizontal chassis 102 from the slag inlet.

[0031] A method for pumping and discharging harmful gases uses the above-mentioned gasifier slag scraper and includes the following steps; When the furnace slag enters the horizontal chassis 102, it falls onto the horizontal section of the slag fishing moving filter plate 201. The slag fishing moving filter plate 201 rotates. The fixed scraping block 401 and the rotating filter plate 402 drive part of the furnace slag to move. When the positions of the fixed scraping block 401 and the rotating filter plate 402 move to the inclined rising section of the slag fishing moving filter plate 201, the rotating filter plate 402 rotates, causing the slag fishing moving filter plate 201, the rotating filter plate 402, the installation filter plate 403, and the fixed scraping block 401 to form an irregular box-shaped container. At this time, the slag fishing moving filter plate 201 stops rotating. The rotating water squeezing plate 501 rotates and drives the water squeezing block 502 to move towards the rotating filter plate 402 to perform the water squeezing work on the furnace slag located in the irregular box-shaped container; After water squeezing is completed, the air extraction partition plate moves into the inclined rising chassis 101, sealing off the inclined rising chassis 101 from the horizontal chassis 102. The air inlet and the air extraction port are opened. Air enters through the air inlet and is extracted through the air extraction port, so that all the harmful gases in the inclined rising chassis 101 are extracted. After the air extraction is completed, the collection box 304 is opened, and the slag in the collection box 304 is discharged. The collection box 304 is closed, the air inlet and the air outlet are closed, and the movable air extraction partition plate 303 is moved out of the slag fishing chassis 1. The slag fishing movable filter plate 201 rotates to transfer the slag after water squeezing into the collection box 304.
