Sludge discharge device for asphalt sludge sedimentation tank and use method thereof

Abstract

The invention relates to the field of sewage treatment equipment, in particular to a sludge discharge device for an asphalt sludge sedimentation tank and a use method of the sludge discharge device. The sludge discharge device comprises an sedimentation tank and further comprises an inverted-U-shaped siphon, the discharge end, located outside the sedimentation tank, of the siphon is connected withan electromagnetic valve, the discharge end of the siphon is connected with the feed port of a water pump, the section, located in the sedimentation tank, of the siphon is sleeved with a floating platform in a sliding mode, a lifting rod is fixed to the floating platform, the upper end of the lifting rod is connected with a triggering mechanism and a destroying mechanism, and the triggering mechanism comprises a sleeve fixed to a vertical frame, a second magnet and a touch switch. The destroying mechanism comprises a gear, a rack I, a rack II and a sealing plunger which are rotatably connected to the vertical frame through a fixed shaft; the sealing plunger can be seamlessly inserted into a column casing in a sleeving manner. According to the sludge discharging device for the asphalt sludge sedimentation tank and the use method thereof, the automation degree is high, the structure is simple, sludge is discharged out of the sedimentation tank through the siphon effect, energy and timeare saved, secondary turbidity of clear liquid cannot be caused, and the sludge discharging efficiency is improved.

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...

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
