Description

Technical Field

[0001] This invention relates to the field of mud treatment technology, specifically to an experimental apparatus for engineering mud treatment. Background Technology

[0002] Engineering sludge refers to cement-containing slurry or semi-solid waste generated during the construction of building projects, municipal projects, underground projects, etc. If engineering sludge is discharged directly without treatment, its high water content (60%-90%) and fluidity can easily lead to the spread of pollutants. Metals (such as lead and cadmium) and chemical additives may seep into the soil or groundwater through rainwater runoff, disrupting the ecological balance. Therefore, engineering sludge needs to be treated. However, existing engineering sludge treatment devices have a slow dewatering speed and low efficiency. Therefore, there is a need to provide a high-efficiency engineering sludge treatment device. Summary of the Invention

[0003] The purpose of this invention is to provide an experimental apparatus for engineering mud treatment to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: An experimental apparatus for engineering mud treatment includes: The tank body has a pretreatment chamber and a solidification chamber inside, which are separated by a partition. The bottom of the solidification chamber has a discharge port. A microwave generator and an ultrasonic transmitter are installed on the outer wall of the tank body. A ring-shaped electrode plate is installed in the pretreatment chamber. The electrode plate is used to induce sludge particle agglomeration. The pretreatment assembly includes a sealing cover disposed on the tank body, a feeding mechanism disposed in the pretreatment chamber, a rotating mechanism and a pressing mechanism disposed on the sealing cover, and a discharging mechanism disposed in the partition plate; The curing assembly includes a curing chamber, a curing mechanism, a discharge mechanism, and a drainage mechanism connected to the feeding mechanism and the curing chamber, respectively. Sludge and flocculant are fed into the pretreatment chamber from the feeding mechanism. The rotating mechanism mixes the sludge and flocculant. The pressing mechanism moves, forcing water from the sludge into the feeding mechanism and then discharging it through the drainage mechanism. When the pressing mechanism presses down on the discharge mechanism, the discharge mechanism connects the pretreatment chamber and the curing chamber. The rotating mechanism rotates, feeding sludge into the curing chamber. The pressing mechanism continues to press down on the discharge mechanism, causing it to again separate the pretreatment chamber and the curing chamber. The curing mechanism then compresses and fixes the sludge, allowing water to pass through the curing mechanism into the curing chamber and then be discharged through the drainage mechanism. The discharge mechanism opens the curing chamber, allowing the sludge loosened by the curing mechanism to be discharged from the discharge port.

[0005] Preferably, the sealing cover is provided with a sludge inlet pipe and a flocculant inlet pipe, and the partition includes a bottom plate disposed on the wall of the pretreatment chamber and an arc plate disposed above the bottom plate.

[0006] Preferably, the feeding mechanism includes a feeding cylinder disposed on the arc plate, a feeding guide plate disposed inside the feeding cylinder, a feeding port formed on the side wall of the feeding cylinder and located above the feeding guide plate, and a filter cloth disposed on the side wall of the feeding cylinder and located below the feeding guide plate.

[0007] Preferably, the feeding mechanism includes a pressing sleeve disposed on the base plate, a pressing trigger rod disposed in the pressing sleeve and passing through the arc plate, an extension spring disposed in the pressing sleeve, a feeding ring disposed at the center of the base plate and the arc plate, a movable inner cavity and an inner ring cavity opened in the feeding ring, a magnet disposed in the movable inner cavity, a connecting rod disposed on the magnet and passing through the feeding ring and connecting to the pressing trigger rod, a magnetic suction ring disposed in the inner ring cavity, and a rubber plug disposed on the magnetic suction ring.

[0008] Preferably, the rotating mechanism includes a rotating motor mounted on the sealing cover, a rotating sleeve mounted on the sealing cover, a rotating rod mounted inside the rotating sleeve, a stirring plate mounted on the rotating rod, a retaining ring mounted on the inner ring cavity, a feeding upper block mounted on the rotating rod and located in the retaining ring, a feeding screw rod mounted on the feeding upper block, and a feeding lower block mounted on the feeding screw rod.

[0009] Preferably, the pressing mechanism includes a pressing telescopic rod disposed on the sealing cover and a pressing protrusion disposed on the pressing telescopic rod and sleeved on the feed cylinder and the pressing sleeve.

[0010] Preferably, sludge and flocculant fall into the feed cylinder from the sludge inlet pipe and flocculant inlet pipe, respectively, and into the pretreatment chamber from the feed inlet. The rotating motor drives the agitator plate to rotate, thereby mixing the sludge and flocculant. The downward pressing telescopic rod is used to drive the downward pressing protrusion to move, pressing down the settled sludge, allowing water to pass through the filter cloth and enter the feed cylinder. When the downward pressing protrusion moves to press down the downward pressing trigger rod, the magnet drives the magnetic block to move down, causing the rubber plug that is attached to the protective ring to disengage from the protective ring, connecting the pretreatment chamber and the compaction box. The rotating motor drives the agitator plate and the feeding screw to rotate again, feeding the sludge into the compaction box through the feeding ring. The downward pressing protrusion presses down again, causing the rubber plug to be fitted onto the feeding lower block, separating the compaction box and the feeding ring.

[0011] Preferably, the bottom of the compression box is provided with a water storage tank, and the compression mechanism includes a sealing ring disposed in the compression box, a base plate disposed in the sealing ring, a filter cloth disposed on the base plate, water permeable holes opened on the base plate, and a compression telescopic rod disposed on the side wall of the compression box.

[0012] Preferably, the material discharge mechanism includes a material discharge gate disposed on the compaction box and a material discharge telescopic rod disposed on the material discharge gate and connected to the compaction cavity wall. The drainage mechanism includes a drainage pump, a lower drainage pipe disposed on the drainage pump and connected to the water storage tank, an upper drainage pipe disposed on the drainage pump and passing through the feed guide plate and connected to the feed pipe, and a water treatment tank connected to the drainage pump.

[0013] Preferably, the compression telescopic rod is used to push the filter cloth to squeeze the sludge into the compression box, so that the water in the sludge flows into the water storage tank through the water permeable hole. The discharge telescopic rod drives the discharge gate to rotate, opening the compression box. The compression telescopic rod moves in the opposite direction to loosen the sludge, and the sludge passes through the discharge gate and is discharged from the discharge port. The drainage pump is used to pump the water in the water storage tank and the feed pipe into the water treatment tank.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes ultrasonic waves to disperse flocculants and achieve demulsification, while an electric field induces particle aggregation, resulting in faster and more efficient dewatering than traditional centrifugal dewatering. The feeding mechanism, controlled by a pressing mechanism that controls the opening and closing of the feeding ring, allows the rotating mechanism to quickly feed the sludge initially drained by the pressing mechanism into the compaction box and fill it completely. This prevents the viscous sludge from clogging the feeding ring. Furthermore, a three-stage moving sealing ring prevents sludge from flowing back into the feeding ring while controlling its opening and closing during sludge compaction. Attached Figure Description
