Description

Technical Field

[0001] The present invention relates to the technical field of mud treatment, and particularly to an experimental device for engineering mud treatment. Background Art

[0002] Engineering sludge refers to the cement slurry or semi-solid waste generated during the construction of construction projects, municipal engineering, underground engineering, etc. If the engineering sludge is directly discharged without treatment, its high water content (60%-90%) and fluidity are likely to cause the diffusion of pollutants. Metals (such as lead and cadmium) and chemical additives may seep into the soil or groundwater through rainwater scouring, destroying the ecological balance. Therefore, it is necessary to treat the engineering sludge. However, when the existing engineering mud treatment device is in use, the dehydration speed is slow and the efficiency is low. Therefore, there is a need to provide an efficient engineering sludge treatment device. Summary of the Invention

[0003] The purpose of the present invention is to provide an experimental device for engineering mud treatment to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

A discharge port is provided at the bottom of the curing chamber. A microwave generator and an ultrasonic transmitter are provided on the outer wall of the tank body. An annularly distributed electrode plate is provided in the pretreatment chamber, and the electrode plate is used to induce the aggregation of sludge particles;

[0008] Solidification assembly, the solidification assembly includes a pressing box arranged in the solidification cavity, a pressing mechanism arranged in the pressing box, a feeding mechanism arranged at the bottom of the pressing box, and a drainage mechanism respectively connected to the feeding mechanism and the pressing box. Sludge and flocculant are fed into the pretreatment cavity from the feeding mechanism to make the rotating mechanism stir and mix the sludge and the flocculant. The pressing mechanism moves to press the water in the sludge into the feeding mechanism and then discharges it through the drainage mechanism. When the pressing mechanism presses down the feeding mechanism, the feeding mechanism communicates the pretreatment cavity and the pressing box. The rotating mechanism rotates to feed the sludge into the pressing box. The pressing mechanism continues to press down the feeding mechanism to make the feeding mechanism cut off the connection between the pretreatment cavity and the pressing box again, so that the pressing mechanism squeezes and fixes the sludge, and the water penetrates through the pressing mechanism into the pressing box and then is discharged through the drainage mechanism. The feeding mechanism opens the pressing box to discharge the sludge released by the pressing mechanism from the discharge port.

[0009] Preferably, a sludge inlet pipe and a flocculant inlet pipe are arranged on the sealing cover. The partition plate includes a bottom plate arranged on the wall of the pretreatment cavity and an arc plate arranged above the bottom plate.

The rotating motor drives the stirring plate to rotate, thereby mixing the sludge and the flocculant. The downward pressing telescopic rod is used to drive the downward pressing convex block to move, pressing the precipitated sludge, so that water permeates through the first filter cloth into the feeding cylinder. When the downward pressing convex block moves to press the downward pressing trigger rod, the magnet drives the magnetic attraction block to move downward, so that the rubber plug attached to the protective ring disengages from the protective ring, connecting the pretreatment chamber and the pressing and solidifying box. The rotating motor drives the stirring plate and the feeding screw rod to rotate again, and sends the sludge into the pressing and solidifying box through the feeding ring. The downward pressing convex block presses downward again, so that the rubber plug sleeves on the downward pressing convex block, separating the pressing and solidifying box and the feeding ring.

The draining mechanism includes a drain pump, a lower drain pipe arranged on the drain pump and communicated with the water storage tank, an upper drain pipe arranged on the drain pump and passing through the feeding guide plate and communicated with the feeding pipe, and a water treatment tank connected to the drain pump.

[0017] Preferably, the pressing and solidifying telescopic rod is used to push the filter cloth to extrude the sludge entering the pressing and solidifying box, so that the water in the sludge flows into the water storage tank through the water permeable holes. The discharging telescopic rod drives the discharging door to rotate, opening the pressing and solidifying box. The pressing and solidifying telescopic rod moves in the reverse direction to loosen the sludge, and the sludge passes through the discharging door and is discharged from the discharging port. The drain pump is used to pump the water in the water storage tank and the feeding pipe into the water treatment tank.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] In the present invention, the flocculant is dispersed by ultrasonic waves to achieve demulsification, and particle aggregation is induced by an electric field, which is faster and more efficient than traditional centrifugal dehydration. Through the setting of the feeding mechanism, the opening and closing of the feeding ring are controlled by the downward pressing mechanism, so that the rotating mechanism can quickly send the sludge that has been initially drained by the downward pressing mechanism into the pressing and solidifying box and fill the pressing and solidifying box, preventing the thickened sludge from blocking the feeding ring. Moreover, the three-stage moving sealing ring prevents sludge from flowing back into the feeding ring while controlling the opening and closing of the feeding ring when pressing and solidifying the sludge.
