Description

Technical Field

[0001] This invention relates to the field of sludge treatment technology, and in particular to a sludge-water separation device for pipe jacking machine operations. Background Technology

[0002] Pipe jacking machines are core equipment used in the construction of trenchless underground tunnels. They achieve tunneling and pipeline laying through the main jacking system and intermediate thrust. When the pipe jacking machine is operating, the cut soil mixes with mud to form sludge, which is transported to the ground mud-water separation equipment through the sludge discharge pipeline to separate the mud and water in the sludge. The separated mud and water can be recycled after treatment, while the separated solids are processed into mud cakes or waste residue.

[0003] In existing technologies, when separating mud and water in sludge, screens are usually used to screen and intercept larger stones. As the separation operation continues, the stones intercepted by the screens will gradually accumulate and form local blockages, affecting the normal flow of sludge. If the accumulated stones are manually moved and cleaned, a lot of manpower and resources are required, increasing the project cost. Moreover, due to the complex working environment, there may be safety hazards. Summary of the Invention

[0010] Furthermore, a guide plate is installed on the inner side of the separation cylinder, wherein the guide plate has an inclined structure, and one end of the guide plate is flush with the drain pipe above the outer side of the separation cylinder; a guide shroud is installed in the middle of the guide plate, and two drive cylinders are installed at the bottom of the guide plate, with the output ends of the two drive cylinders moving upward and movably installed at the bottom of the counterweight ring.

[0011] Furthermore, a guide plate is installed on the inner bottom of the separation cylinder; one end of the guide plate is flush with the drain pipe below the outer side of the separation cylinder, and a squeezing vertical cylinder is installed on the top of the guide plate; an opening is provided on the outer side of the squeezing vertical cylinder, the top of the squeezing vertical cylinder is located outside the bottom of the flow guide shroud, and a rotating wheel is rotatably installed at the edge of the top of the squeezing vertical cylinder.

[0012] Furthermore, a servo motor is installed on the top of the outer side of the extrusion cylinder, and a gear is installed on the output end of the servo motor.

This avoids the accumulation problem that is easily caused by traditional planar structures and improves the efficiency of water discharge through the openings. The rotation of the rotating separation hood provides centrifugal force for mud-water separation, so that the separated water flows through the openings of the rotating separation hood, falls onto the guide plate, and is discharged through the drain pipe on the outside of the separation cylinder along the inclined surface. The initial separation is combined with the rotation of the rotating plates to perform a squeezing separation method, which improves the mud-water separation effect in the sludge.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please refer to Figures 1 to 9 : Example 1: This invention proposes a mud-water separation device for pipe jacking machine operations, comprising: a separation cylinder 1, which is cylindrical in shape; two vertically distributed drain pipes are installed on the outer side of the separation cylinder 1; support legs are installed on the outer side of the separation cylinder 1; and a feed hood 101 is installed on the top of the separation cylinder 1; discharge hoods 102 are installed on both sides of the feed hood 101; and two positioning and fixing rods 103 are installed on the inner side of the feed hood 101; the positioning and fixing rods 103 are cylindrical in shape, and multiple evenly distributed positioning side plates 104 are installed on the outer side of the two positioning and fixing rods 103; the multiple positioning side plates 104... Separation slide rails 105 are installed at the edges of 04; guide scraper rings 106 are slidably installed on the outer side of multiple separation slide rails 105, and connecting rods 107 are installed on the outer side of multiple guide scraper rings 106; a servo motor is installed on the outer side of the feed hood 101, and a rotating rod 108 is installed on the output end of the servo motor; the rotating rod 108 passes through the middle position of the positioning side plate 104 and is installed on the inner side of the feed hood 101; a telescopic rod assembly 109 is installed on the outer side of the rotating rod 108; a sliding sleeve 1010 is installed on the side end of the telescopic rod assembly 109; the sliding sleeve 1010 is rotatably installed on one end of the connecting rod 107.

[0023] In this embodiment of the invention, when the pipe jacking machine separates the mud and water in the generated sludge, the sludge flows through the pipe into the feed hood 101 at the top of the separation cylinder 1. The positioning side plate 104 on the positioning and fixing rod 103 and the separation slide rail 105 are evenly distributed to intercept larger stones in the sludge. The servo motor on the outside of the feed hood 101 drives the rotating rod 108 to rotate. The outside of the rotating rod 108 drives the sliding sleeve 1010 to move through the telescopic rod assembly 109. The sliding sleeve 1010 rotates on one end of the connecting rod 107. Since the guide scraper ring 106 on the connecting rod 107 can move along the outside of the separation slide rail 105, the separation slide rail 105 limits the movement position of the guide scraper ring 106, so that the guide scraper ring 106 moves circumferentially along the separation slide rail 105. When the sliding sleeve 1010 moves the connecting rod 107, the connecting rod 107 moves the guide scraper ring 106 along the separation slide rail 105 on the positioning side plate 104. The guide scraper ring 106 rotates cyclically along the separation slide rail 105, pushing the stones intercepted on the separation slide rail 105. The telescopic rod assembly 109 moves in and out with the rotation of the sliding sleeve 1010, causing the guide scraper ring 106 to complete a circular motion. This causes the guide scraper ring 106 and the connecting rod 107 to push the intercepted stones toward one end of the feed hood 101, so that the stones fall into the discharge hood 102 and are discharged through the discharge hood 102. This reduces the amount of manual cleaning work. By replacing manual work with a servo motor, the work efficiency is greatly improved, reducing human intervention and safety hazards.

[0024] In Example 2, based on Example 1, a positioning plate 2 is installed on the inner side of the separation cylinder 1. The positioning plate 2 has an annular structure and is located below the separation slide rail 105. A rotating wheel 201 is rotatably mounted on the positioning plate 2, wherein the top of the rotating wheel 201 has an inclined structure. A servo motor is installed on the outer side of the separation cylinder 1, and a gear is installed on the output end of the servo motor. The gear meshes with the side of the rotating wheel 201. A rotating separation cover 202 is installed at the bottom of the rotating wheel 201. The rotating separation cover 202 has a stepped structure, and an opening is provided on the outer side of the rotating separation cover 202. A movable support plate 203 is slidably mounted inside the rotating separation cover 202. The movable support plate 203 has an annular structure and is slidably mounted on the outer side of the rotating separation cover 202. A guide rod 204 is installed at the bottom of the pallet 203; a counterweight ring 205 is installed at the bottom of the guide rod 204, which passes through the bottom of the rotating separation hood 202; a traction rod 206 is installed at the top of the movable pallet 203; a sealing plate 208 is slidably installed at the middle position of the bottom inner side of the rotating separation hood 202; the top of the sealing plate 208 is a conical structure, and a support rod 207 is installed at the top of the sealing plate 208; the top of the support rod 207 is connected to the middle position of the traction rod 206; a guide plate 209 is installed on the inner side of the separation cylinder 1, wherein the guide plate 209 is an inclined structure, and one end of the guide plate 209 is flush with the drain pipe above the outer side of the separation cylinder 1; a guide rod is installed at the middle position of the guide plate 209. The flow hood 2010 and the bottom of the guide plate 209 are equipped with two drive cylinders. The output ends of the two drive cylinders are moved upward and movably installed at the bottom of the counterweight ring 205. When the pipe jacking machine separates the mud and water in the generated sludge, the mud and water fall inside the rotating separation hood 202. Due to the stepped distribution of the rotating separation hood 202, the mud and water are distributed in a stepped manner inside the rotating separation hood 202, reducing the problem of incomplete separation due to mud and water accumulation. The gear at the output end of the servo motor on the outside of the separation cylinder 1 drives the rotating wheel 201 to rotate on the top of the positioning plate 2. After the rotating separation hood 202 rotates, the water in the sludge flows out through the opening on the outside of the rotating separation hood 202, and the water flows onto the guide plate 209 and through the separation cylinder 1. The sludge flows out through the upper outer drain pipe for initial sludge separation. The output ends of the two drive cylinders at the bottom of the guide plate 209 move upward, pushing the counterweight ring 205 upward. The top of the counterweight ring 205 pushes the movable support plate 203 upward through the guide rod 204. The top of the movable support plate 203 drives the support rod 207 upward through the traction rod 206. The bottom of the support rod 207 drives the sealing plate 208 upward and away. The upward movement of the movable support plate 203 causes the separated solid sludge to move upward. The conical structure at the top of the sealing plate 208 causes the sludge to move outward, allowing it to move downward through the bottom of the inner side of the rotating separation cover 202, and then downward through the guide cover 2010.

[0025] In Example 3, based on Example 1, a guide plate 3 is installed on the inner bottom of the separation cylinder 1; one end of the guide plate 3 is flush with the drain pipe below the outer side of the separation cylinder 1, and a compression vertical cylinder 301 is installed on the top of the guide plate 3; an opening is provided on the outer side of the compression vertical cylinder 301, the top of the compression vertical cylinder 301 is located outside the bottom of the guide shroud 2010, and a rotating wheel 302 is rotatably installed at the edge of the top of the compression vertical cylinder 301; a servo motor is installed on the top of the outer side of the compression vertical cylinder 301, and a gear is installed on the output end of the servo motor, the side of the gear meshing with the side of the rotating wheel 302; the rotating wheel A rotating blade 303 is installed inside the extrusion cylinder 301. The rotating blade 303 has a spiral structure and is rotatably installed inside the extrusion cylinder 301. A discharge plate 304 is installed at the bottom of the separation cylinder 1. A spring is installed at the bottom of the discharge plate 304, and a movable plate 305 is installed at the bottom of the discharge plate 304 via the spring. A guide slide rod 306 is installed at the middle position of the top of the movable plate 305. A protrusion is provided on the outer side of the guide slide rod 306, and a sealing plate 307 is installed through the middle position of the discharge plate 304 at the top of the guide slide rod 306. The sealing plate 307 is slidably installed on the bottom of the extrusion cylinder 301. During the pipe jacking operation, when separating mud and water from the generated sludge, the separated mud and sludge fall into the inner side of the extrusion cylinder 301 through the guide hood 2010. The gear on the output end of the servo motor on the outside of the extrusion cylinder 301 drives the rotating wheel 302 to rotate at the top of the extrusion cylinder 301. The inner side of the rotating wheel 302 drives the rotating plate 303 to rotate inside the extrusion cylinder 301. Under the action of the spring at the top of the movable plate 305 at the bottom of the guide slide rod 306, the sealing plate 307 has a large elastic force, causing the sealing plate 307 to block the bottom of the extrusion cylinder 301. As the rotating plate 303 rotates... The residual water in the sludge is squeezed out, and the sludge-water separation operation is further carried out. The water flows out through the opening on the outside of the squeezing vertical cylinder 301. The guide plate 3 collects the water flow and it flows out through the drain pipe on the lower outside of the separation cylinder 1. The rotating plate 303 continues to rotate and the sludge accumulates, which pushes the sealing plate 307 to move downward. The bottom of the sealing plate 307 moves downward through the discharge plate 304 via the guide slide rod 306. The bottom of the guide slide rod 306 drives the spring on the movable plate 305 to stretch, so that the sludge moves outward through the sealing plate 307 and the top of the discharge plate 304, and the separated solid sludge is discharged.

[0026] The working principle of this embodiment is as follows: Sludge flows into the feed hood 101 through the pipe. The positioning side plate 104 on the positioning fixing rod 103 and the separation slide rail 105 intercept larger stones in the sludge-water mixture. The servo motor on the outside of the feed hood 101 drives the rotating rod 108 to rotate. The outside of the rotating rod 108 drives the sliding sleeve 1010 to rotate on one end of the connecting rod 107 through the telescopic rod assembly 109. The connecting rod 107 drives the guide scraper ring 106 to push the intercepted stones along the separation slide rail 105. The intercepted stones fall into the discharge hood 102 and are discharged. The sludge-water steps are distributed on the inside of the rotating separation hood 202. The gear at the output end of the servo motor on the outside of the separation cylinder 1 drives the rotating wheel 201 to rotate, which in turn drives the rotating separation hood 202 to rotate, so that the water in the sludge flows out through the opening on the outside of the rotating separation hood 202. The water flows onto the guide plate 209 and flows out through the drain pipe above the outside of the separation cylinder 1. The two bottoms of the guide plate 209 The output end of the drive cylinder pushes the counterweight ring 205 upward, which in turn drives the movable pallet 203 to move upward through the guide rod 204. The upward movement of the movable pallet 203 causes the separated solid sludge to move upward and be pushed outward. The sealing plate 208 moves upward, causing the sludge to move outward. The sludge moves downward through the bottom of the inner side of the rotating separation cover 202 and falls into the inner side of the extrusion cylinder 301 through the guide cover 2010. The gear on the output end of the servo motor on the outer side of the extrusion cylinder 301 drives the rotating wheel 302 and the rotating plate 303 to rotate inside the extrusion cylinder 301. The rotation of the rotating plate 303 squeezes out the residual water in the sludge. The water flows out through the opening on the outer side of the extrusion cylinder 301. As the rotating plate 303 continues to rotate, the accumulated sludge will push the sealing plate 307 downward. The bottom of the sealing plate 307 is stretched by the spring on the movable plate 305 through the guide slide rod 306. The solid sludge is discharged through the sealing plate 307 and the top of the discharge plate 304.
