A sludge discharge device for asphalt sludge settling tank and using method thereof

Abstract

The invention relates to the field of sewage treatment equipment, in particular to a sludge discharge device for an asphalt sludge settling tank and a method for using the same, including a settling tank and an inverted U-shaped siphon, the discharge end of which is located outside the settling tank and connected to a solenoid valve , the discharge end of the siphon tube is connected to the feed port of the water pump. A section of the siphon tube located inside the settling tank is slidingly sleeved with a floating platform, and a lifting rod is fixed on the floating platform. The upper end of the lifting rod is connected to the trigger mechanism and the destroying mechanism. The trigger mechanism It includes the sleeve fixed on the stand, the second magnet and the touch switch. The destroying mechanism includes the gear, the rack one, the second rack and the sealing plug connected to the stand by fixed axis rotation. The sealing plug can be inserted seamlessly. Set inside the cylinder. The sludge discharge device for the asphalt sludge settling tank and its use method have a high degree of automation and a simple structure. The siphon effect is used to discharge the sludge from the settling tank, which saves energy, time and labor, does not cause secondary turbidity of the clear liquid, and improves drainage. mud efficiency.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a sludge discharge device for an asphalt sludge settling tank and a use method thereof. Background technique [0002] Asphalt is a waterproof, moisture-proof and anti-corrosion organic gelling material. It is a dark brown complex mixture composed of different molecular weight hydrocarbons and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is liquid and the surface is black. , soluble in carbon disulfide. Asphalt can be mainly divided into three types: coal tar pitch, petroleum pitch and natural pitch. During the production of asphalt, a large amount of sewage and wastewater will be produced. If these pollutants are not treated, they will cause environmental damage. During the treatment of asphalt products, the sewage and wastewater need to be settled first. For example, application number 201510835210.7 discloses an asphalt sludge thi...

Problems solved by technology

During the production of asphalt, a large amount of sewage and wastewater will be produced. If these pollutants are not treated, they will cause environmental damage. During the treatment of asphalt products, the sewage and wastewater need to be settled first. For example, application number 201510835210.7 discloses an asphalt sludge thickening device, which gathers and pushes out the sludge through an inclined mud pusher, but the clear liquid and sludge will be disturbed during the process of pushing the mud by the inclined mud pusher. mud, which reduces the settling efficiency, and the sludge discharge efficiency is also poor. In view of this, we propose a sludge discharge device for asphalt sludge settling tank and its use method
