Bent tube type slag water sealing squeezing slag removal machine

Abstract

The present invention provides a bent-tube type slag water sealing and squeezing slag extractor. A driving part pushes a squeeze head into a squeeze chamber; the outlet of a slag-feeding funnel is connected with the squeeze chamber which is connected with one end of a bent shell; the other end of the bent shell is a slag outlet; the bent part of the bent shell is lower than a compression chamber;and the side of the slag-feeding funnel is communicated with a water-replenishing tank. The compression chamber is inclined downwards; the lower opening of the compression chamber is connected with the bent shell in the form of natural transition; a water level controller is arranged inside the water-replenishing tank; and the water level of the water-replenishing tank is higher than the sealed opening of the upper opening of the compression chamber. A slag water separation section, which is assembled between the bent shell and the slag outlet, comprises a material-discharging shell connectedwith the bent shell; wherein, water-filtering holes are arranged on the tubular wall of the material-discharging shell; the slag outlet is the outlet of the material-discharging shell; a shield larger than the material-discharging shell is nested outside the material-discharging shell; both ends of the shield are hermetically connected with the material-discharging shell; and the lower part of the shield is provided with a water outlet. The driving part adopts a hydraulic cylinder.

Description

technical field [0001] The invention relates to an elbow type slag-water sealing extrusion slag discharger, which is mainly used as supporting equipment for discharging coal slag from the bottom of a fixed-layer gas generator (commonly known as a gas generator in the industry). Especially the automatic continuous extrusion slagging machine for gas generator. Background technique [0002] At present, the normal working pressure in the gas-making furnace used in the chemical industry is 0.02-0.1 MPa, and the intermittent open slagging method is adopted, and the pressure in the furnace is zero when slagging. The slag discharge is carried out every 1-2 hours of the gas-making furnace, and the gas-making furnace is shut down for 5-10 minutes each time the slag is discharged, and the opening and closing of the slag discharge port is controlled by a hydraulic flap valve. They are stacked and stored at the yard, and then transported outside the factory area by large trucks. This s...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the open slag discharge method, the working pressure in the furnace is zero during slag discharge, forcing the gas generator to stop production during slag discharge, and can only work in a periodic intermittent production mode, which reduces the gas production to a certain extent furnace output

[0004] 2. Since the slag storage tank must be sprayed with water to cool before slag discharge, the wet slag will adhere to the sealing surface of the slag discharge port when it flows out, seriously affecting its sealing effect, causing a large amount of sewage and a small amount of gas to leak out, both pollute the environment and waste energy

[0005] 3. Due to the limitation of its intermittent slag discharge method, it can only be transported multiple times with a trolley, the working environment is harsh, and the labor intensity of the workers is relatively high, so it is difficult to realize fully automatic mechanized production
