Description

Technical Field

[0001] The invention mainly relates to the technical field of sewage treatment, and in particular to a bridge mud sewage treatment system. Background Art

[0002] Bridge mud is engineering mud, which is a semi-colloidal suspension formed by the dispersion of tiny particles of clay in water and mixing with water. A large amount of engineering mud is produced in the construction of underground projects such as shield tunneling, pile foundation, and underground continuous wall. One cubic meter of natural soil can produce 4-5 cubic meters of mud, and each foundation project usually produces thousands or even hundreds of thousands of cubic meters of mud. The use of mud can prevent hole collapse, suspend rock debris, and safely pass through the quicksand layer. The correct use of mud can ensure safe drilling. However, excessive use of mud will bring many difficulties to well washing and affect the water output. Therefore, when using mud, it must be thickened or diluted at any time according to the different properties of the formation. The performance of mud usually refers to the water content, fineness (or residue), specific gravity (or density), fluidity and thixotropy, slurry absorption speed and other indicators of mud.

[0003] According to a mud dewatering device for mud sewage treatment provided by the patent document with application number CN202311489316.7, the device includes a frame, support frames are fixedly connected to both sides of the outer surface of the frame, a top frame is fixedly connected to the upper surface of the frame, a fixed plate is fixedly connected to the surface of the top frame, and a motor is fixedly connected to the surface of the fixed plate.

[0004] When the muddy sewage in the product of the above patent is drained by the guide block, part of the muddy sewage will impact the swing blocks on both sides of the expansion block. The impact force generated by the muddy sewage discharge cannot be evenly distributed on the surface of the swing blocks on both sides, so that the swing blocks drive the through rod to rotate on the lower surface of the sleeve block. Since the swing block belt is connected to the surface of the expansion block through an elastic belt, the elastic belt on one side is pulled when the swing block rotates, and the elastic belt on the other side shrinks inward, thereby changing the path of the muddy sewage on the surface of the conveying plate, which facilitates the dispersion of the muddy sewage to both sides of the conveying plate. When filtering the muddy sewage of the bridge, the granular objects need to be filtered before spiral sedimentation to prevent damage to the spiral sedimentation equipment. Summary of the invention

[0026] It should be noted that, in the present embodiment, when the mud is thicker, the first electric telescopic rod 231 can be started, and the first electric telescopic rod 231 drives the pressing plate 232 to squeeze the mud on the top of the filter plate 12, and squeeze a certain amount of mud and water to the bottom of the tank body 10, and then the rotating motor 211 is started, and the rotating motor 211 drives the rotating rod 22 to rotate, and the second electric telescopic rod 241 is started to drive the lifting circular plate 242 to move upward, and stop when it reaches the specified position. At this time, the wedge block on the lifting circular plate 242 can touch the wedge block at the bottom of the filter plate 12 when it rotates, and then the lifting circular plate 242 is driven to rotate under the rotation of the rotating rod 22. When the wedge block on the lifting circular plate 242 touches the wedge block at the bottom of the filter plate 12, the filter plate 12 is pushed upward, and then the spring 193 pulls the filter plate 12 back, causing it to vibrate to screen the mud on the top of the filter plate 12, and the stones on the filter plate 12 are left on the filter plate 12 by the squeezing of the pressing plate 232; When the gravel reaches the preset position, the rotating motor 171 is started to drive the sealing plate 172 to rotate and open the discharge port 16.

The scraper 25 hangs the mud on the side wall below the tank body 10 to reduce the mud attached to the inner wall of the tank body 10. Then the above operation is repeated to filter the granular objects in the mud, so that the spiral sedimentation equipment can better separate the bridge mud from the solid and liquid.

[0027] The working principle of the present invention is: The electrical components in the present invention are all triggered to operate by a PLC controller.

[0028] First, the bridge mud is pumped into the tank body 10 through the feeding mechanism, and then the detector 131 detects the mud position according to the safety line. When it reaches the safety line, the data is sent to the PLC controller, and the PLC controller analyzes the data, and then stops the feeding mechanism. The filter plate 12 filters the stones at the top, and the mud flows into the bottom of the tank body 10. When the mud is thick, the first electric telescopic rod 231 can be started, and the first electric telescopic rod 231 drives the pressing plate 232 to squeeze the mud on the top of the filter plate 12, and squeezes a certain amount of mud and water to the bottom of the tank body 10, and then the rotating motor 211 is started, and the rotating motor 211 drives the rotating motor 211 to drive ... The rod 22 rotates, and the second electric telescopic rod 241 is started to drive the lifting circular plate 242 to move upward, and stops when it reaches the specified position. At this time, the wedge-shaped block on the lifting circular plate 242 can touch the wedge-shaped block at the bottom of the filter plate 12 when it rotates, and then the lifting circular plate 242 is driven to rotate under the rotation of the rotating rod 22. When the wedge-shaped block on the lifting circular plate 242 touches the wedge-shaped block at the bottom of the filter plate 12, the filter plate 12 is pushed upward, and then the spring 193 pulls the filter plate 12 back, so that it vibrates to screen the mud on the top of the filter plate 12, and the stones on the filter plate 12 are left on the filter plate 12 by the squeezing of the pressing plate 232; When the gravel reaches the preset position, the rotating motor 171 is started to drive the sealing plate 172 to rotate and open the discharge port 16. Then the filter plate 12 vibrates to send the filtered waste out of the discharge port 16. After the sending is completed, the sealing plate 172 is closed to continue to extract the bridge mud and filter the gravel. When the rotating rod 22 rotates, it drives the scraper 25 to scrape the mud on the side wall below the tank body 10. Then the water pump 1811 is started to draw the filtered mud under the tank body 10 from the pipe 2 18 into the pipe 3 1812 and then enter the spiral sedimentation equipment to separate the mud from the solid and liquid. The scraper 25 hangs the mud on the side wall below the tank body 10 to reduce the mud attached to the inner wall of the tank body 10. Then the above operation is repeated to filter the granular objects in the mud, so that the spiral sedimentation equipment can better separate the bridge mud from the solid and liquid.
