Description

Technical Field

[0001] The utility model relates to the technical field of slag discharging devices, in particular to a solid slag discharging device for a salt-containing waste liquid incinerator. Background Art

[0002] In the traditional process of incinerating and treating salt-containing waste liquid, due to the low melting point of inorganic salts (800 - 900°C) and the incineration temperature in the furnace being 1100°C, molten inorganic salts often adhere to the furnace wall, or remain in the ash hopper and agglomerate, making it difficult for the ash to fall, and even entering the subsequent section with the flue gas and clogging the equipment, resulting in the system being unable to operate continuously and stably.

[0003] Currently, the existing technologies can only meet the problem of incinerating salt-containing waste liquid, but the inorganic salts in the equipment need to be frequently cleaned, which causes the system to not operate stably for a long time. A large amount of labor is required to clean the inorganic salts in the equipment, which not only increases the labor cost but also increases many unsafe factors during operation.

[0004] CN102877806A discloses a slag discharging device, which consists of a drill bit, a drill rod, a conical baffle, a drill bit seat, etc. The conical baffle is arranged at the lower end of the drill bit seat. The drill rod passes through the conical baffle and the drill bit seat. The drill bit is arranged at the bottom end of the drill rod. The drill rod is connected to an exhaust fan or other devices to exhaust air through the hollow air duct in the drill rod, and the direction or angle is adjusted through a guiding mechanism arranged on the mast. It is mainly a slag discharging device used for cutting drills to complete slag discharging while drilling, controlling slag discharging dust, and reducing the temperature of the drill bit, with a simple structure and convenient use and maintenance.

[0005] CN111569482A discloses a slag discharging device, including a material guiding groove and a water receiving groove arranged below the slag discharging port of a dehydration mechanism. The material guiding groove is assembled to be movably arranged between the following two working positions: Working position one, the material guiding groove is inclined and located below the slag discharging port; and working position two, the material guiding groove is located beside the slag discharging port below to avoid the area between the slag discharging port and the water receiving groove. It also includes a conveyor belt, and the lower end of the material guiding groove in the state of working position one is used to collect the materials sliding down from the material guiding groove. During the operation of the dehydration mechanism, a small amount of water will overflow from the equipment gap. In order to prevent these water droplets from falling on the dehydrated mud slag, the slag discharging device is set as a movable structure. When discharging slag, the material guiding groove moves to below the slag discharging port to guide the mud slag to fall onto the conveyor belt. When not discharging slag, the material guiding groove is removed from below the slag discharging port, so that the overflowing water droplets fall into the water receiving groove, effectively avoiding the secondary mixing of water and mud slag.

[0006] CN213288604U discloses a slag discharging device for the protective slag in a mold. The slag discharger is arranged on a mounting frame installed above the liquid level of the mold. An air inlet is provided at the upper part of the slag discharging pipe in the slag discharger. The air inlet is communicated with an inert gas cylinder through an air inlet pipe. The top end of the slag discharging pipe has a cover plate, and a bottom seal is installed at the bottom end. An opening is provided on the cover plate to facilitate the insertion of materials or detection equipment into the slag discharging pipe. The air inlet is located below the cover plate and above the liquid level of the protective slag in the mold, and the bottom seal is located below the liquid level of the molten steel in the mold. This device enables the detection equipment or materials that need to be immersed in the molten steel to pass through the protective slag layer without contacting the protective slag. Thus, it can avoid the contact between external detection equipment or materials and the protective slag, and also prevent the oxidation of the molten steel surface.

[0007] CN105599938A discloses a slag discharging device, which includes a sealing block, an upper pipe orifice, a lower pipe orifice, an actuator, a connecting rod, and a support base. Among them, the upper part of the lower pipe orifice is fixedly connected to the lower part of the upper pipe orifice. The inner diameter of the lower pipe orifice is larger than that of the upper pipe orifice. A sealing surface is provided at the bottom of the upper pipe orifice. The sealing block is matched with the bottom of the upper pipe orifice and sealed through the sealing surface. The support base is fixedly installed at the bottom of the lower pipe orifice, and the actuator is fixedly installed on the support base and connected to the sealing block through the connecting rod. Through the action of the actuator, the connecting rod can be lifted and lowered, driving the up and down movement of the sealing block, and playing the role of opening and closing the upper pipe orifice, thereby realizing the slag discharging function. It has the advantages of simple structure, convenient operation, not easy to be blocked, controllable discharge path, and safe operation, improving the slag discharging efficiency.
