Description

Technical Field

[0001] The invention relates to the technical field of sludge treatment, and in particular to a sludge treatment device and method at a shaft construction site. Background Art

[0002] During the shaft construction process, a large amount of sludge is often produced due to complex geological conditions and abundant groundwater. If this sludge is not handled in time, it will not only occupy a large amount of space and affect the construction progress, but may also cause pollution to the surrounding environment.

[0003] The Chinese patent proposes a sludge dewatering treatment device for a water conservancy construction site, with the publication number CN217757224U, comprising a device body, a shell installed on the outside of the device body, a dewatering box fixedly installed inside the shell, a first hydraulic rod installed on the top of the inside of the dewatering box, a pressure plate fixedly installed on the bottom of the first hydraulic rod, a drainage port opened on one side of the dewatering box, a filter plate fixedly installed inside the drainage port, a cleaning port opened on the other side of the dewatering box, a vibration motor fixedly installed on one side of the shell, a transmission rod installed on one side of the vibration motor, a mounting plate installed on one end of the transmission rod, a plurality of transmission plates fixedly installed on one side of the mounting plate, a second hydraulic rod installed on the other side of the inside of the shell, a push plate fixedly installed on one end of the second hydraulic rod.

[0004] The above-mentioned device achieves the effect of separating mud and water from sludge by means of filter pressing. However, by compressing the sludge into a solid state through a pressing plate, only the water in the outer layer of the sludge can be squeezed out, while the water contained in the inner layer of the sludge cannot be fully pressed out because it cannot withstand the pressure well, resulting in the final treated sludge still containing a large amount of water, affecting the sludge treatment effect.

[0005] Therefore, the design is highly practical and can drive the rotating rod to rotate through the second bevel gear transmission assembly when the first rotating rod rotates. The rotating rod and the filter cartridge rotate in opposite directions, so that the hollow tube on the rotating rod can stir the sludge in the filter cartridge. Reverse stirring helps to break the floc structure in the sludge and release more water, thereby improving the dehydration effect. At the same time, it can also prevent the sludge from depositing in the filter cartridge, ensuring that the entire sludge layer can be evenly treated. A sludge treatment device and method for a shaft construction site is very necessary. Summary of the invention

[0015] Based on the above-mentioned sludge treatment device at a shaft construction site, the present invention also proposes a sludge treatment method at a shaft construction site, comprising the following steps: Step 1: The sludge generated by the shaft construction is transported to the dewatering barrel through the screw feeder, and the sludge is guided by the guide hopper to fall into the filter cartridge; Step 2: Start the stepper motor to make the filter cartridge separate the sludge from water, so that the water in the sludge is thrown into the water storage chamber, and the solid sludge remains in the filter cartridge. At the same time, the rotating rod rotates in the opposite direction to the filter cartridge, and drives the hollow tube to heat and stir the sludge in the filter cartridge; Step 3: The dehydrated sludge falls into the collection box through the discharge pipe of the solenoid valve. The rotating rod drives the scraper to perform secondary heating and stirring on the dehydrated sludge so that the residual water in the dehydrated sludge can be evaporated by heat: Step 4: The dehydrated dry mud is quantitatively discharged by opening the quantitative valve of the discharge pipe. The discharged dry mud is transmitted to the outside through the conveying device and recovered.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, when the first rotating rod rotates, the second bevel gear transmission assembly can drive the rotating rod to rotate. The rotating rod rotates in opposite directions to the filter cartridge, so that the hollow tube on the rotating rod can stir the sludge in the filter cartridge. The reverse stirring helps to break the floc structure in the sludge, release more water, thereby improving the dehydration effect, and at the same time prevents the sludge from being deposited in the filter cartridge, ensuring that the entire sludge layer can be evenly treated.

[0017] 2. The present invention can drive the fan blades in the box to rotate when the first rotating rod rotates, so that the outside air can enter the box through the dustproof ventilation net at the bottom of the box, and then form hot air through the heating wire. The generated hot air enters the hollow cavity through the air inlet on the rotating rod, and is discharged through the air outlets on a plurality of hollow tubes connected thereto. The discharged hot air can heat the sludge being stirred, increase the sludge temperature, thereby reducing the viscosity of the water, making it easier to remove the water, and at the same time can promote the degradation of organic matter in the sludge and reduce the volume and weight of the sludge.

[0018] 3. In the present invention, when the rotating rod rotates, the scraper rod can be driven to rotate through the fixed ring. The scraper rod can scrape off the sludge attached to the inner wall of the filter cartridge, thereby improving the dehydration effect and allowing the sludge to be heated more evenly. The arrangement of the scraper rod can ensure that the dehydrated sludge is fully discharged into the collection box. Since the electric heating wire generates heat in the box, the box can generate heat, so that the sludge falling into the collection box can be further heated. At the same time, the rotating rod drives the scraper on the connecting rod through the mounting ring to stir the sludge in the collection box again, so that the sludge is fully heated again, thereby greatly reducing the water content in the sludge.
