Description

Technical Field

[0001] This invention specifically relates to the field of mud purification, separation, and screening technology, and more specifically to a separation and screening device for mud purification. Background Technology

[0002] Currently, in engineering operations such as pile foundation construction, diaphragm wall construction, shield tunneling, and geological drilling, a large amount of mud is required for wall protection, cuttings carrying, cooling of drilling tools, and balancing of formation pressure. During construction, a large amount of rock and soil debris, sand, gravel, and soil impurities generated by the drill bit cutting the formation will continuously mix into the circulating mud, causing the solid content of the mud to increase continuously, the sand content to exceed the standard, and the mud viscosity and specific gravity to become unbalanced, resulting in a significant decrease in the original wall protection performance and the ability to suspend and carry cuttings. If the mud is not purified for a long time, the accumulation of a large amount of solid particles will cause excessive sediment at the bottom of the hole, which will directly reduce the bearing capacity of the pile foundation and easily lead to construction safety hazards such as hole wall collapse and hole shrinkage, seriously affecting the quality of engineering construction. At the same time, the hard sand particles mixed in the mud will cause serious abrasion to equipment such as mud pump impeller, delivery pipeline, and valve, accelerating equipment wear and shortening service life. It can also easily cause pipeline blockage and poor circulation system, leading to construction interruption. Traditional screening devices mostly rely on natural sedimentation. While this achieves the screening effect, its efficiency is low during on-site operations. Multiple screening layers are required, and these layers are prone to clogging, affecting the screening quality. Furthermore, traditional devices cannot be cleaned effectively. Over time, a large amount of impurities accumulate on the screening device, increasing its weight and further impacting screening quality. If a large amount of impurities cannot be cleaned in a timely manner, prolonged use will cause wear and tear on the screening device. Summary of the Invention

[0003] The purpose of this invention is to provide a separation and screening device for mud purification. In this device, mud is pumped into a mud silo by a pump. Two first vibrating motors vibrate the mud silo to prevent blockage. When the mud falls onto the vibrating screen below, a second vibrating motor drives the screen to screen larger particles of impurities. Because the vibrating screen is inclined, impurities automatically separate from it during vibration. The separated mud is transferred to the feed hopper through the separation chamber. The drive motor drives the auger on the rotating shaft to transport the mud forward to the purification screen. The purification screen screens smaller particles of impurities. The impurities screened through the purification screen are transferred to the discharge pipe installed at the bottom of the fixed cover by the rotation of the purification screen. The purified mud falls into the collection chamber. During use, the purification screen can be washed by nozzles installed at the bottom of the backwashing frame to prevent blockage and ensure the quality of mud purification, thus solving the problems mentioned in the background art.

[0007] As a further technical solution of the present invention, a feed hopper is fixedly installed on the top of the shell; the feed hopper cooperates with the discharge pipe at the bottom of the separation chamber; the feed hopper is located above the auger, and after the slurry enters the shell, the auger slows down the transmission speed of the slurry, so that the slurry has a certain self-settling effect.

The fastening member is fastened and installed on the outside of the connecting rod 142, and the outer surfaces of both sets of connecting rods 142 are fixedly connected to the chain 138.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In use, when the first vibrating motor drives the mud silo to vibrate, the bottom of the mounting frame cooperates with the top of the support frame through the first spring to ensure the vibration efficiency of the mud silo and avoid the mud from clogging in the mud silo. The mud falls onto the vibrating screen below during the vibration process. 2. In this invention, a second vibrating motor is fixedly installed at the bottom of one end of the vibrating screen to drive the vibrating screen to vibrate. At this time, the vibrating screen is movably installed between the support column and the second spring and the support frame. This can ensure that the vibrating screen can screen larger particles of impurities. Since the vibrating screen is set at an inclination, during the vibration of the vibrating screen, the screened impurities are automatically vibrated and transmitted downwards through the inclination angle of the vibrating screen, realizing the automatic separation of impurities from the vibrating screen, avoiding the impurities from clogging the vibrating screen and the wear of the vibrating screen caused by long-term vibration. 3. In this invention, the slurry after being screened by a vibrating screen is transferred to the feed hopper through a separation chamber. During the process of the drive motor driving the rotating shaft to rotate, the bottom of the feed hopper is fixedly installed with the shell, so as to transfer the slurry into the shell. Then, the auger installed on the rotating shaft is used to transfer the slurry forward, thereby reducing the transfer speed of the slurry and giving the slurry a certain self-settling effect. 4. In this invention, the rotation of the auger transfers the slurry to the purification screen for further screening. The rotating shaft is fixedly installed to the inner wall of the purification screen via a connecting rod, so that the purification screen and the rotating shaft rotate synchronously. During the purification and screening process, the slurry is purified. At the same time, as the purification screen rotates, the screened impurities are transferred to the discharge pipe at the bottom of the fixed cover at the other end for discharge. The purified slurry is then transferred to the collection chamber at the bottom of the mounting shell. 5. In this invention, when further purifying the mud through a purification screen, one end of the backwashing frame fixedly installed on the top of the housing is connected to a water source. The pump body draws clean water to achieve automatic cleaning of the nozzle installed at the bottom of the backwashing frame and the surface of the purification screen. This effectively avoids clogging of the purification screen and ensures the purification quality of the mud by the purification screen. 6. In this invention, after the slurry to be processed is added to the feeding box, the feeding motor installed on the top of the bracket drives the support rod to rotate, and the sprockets on the multiple support rods drive the chain to rotate. The chain is fixedly installed with the connecting rod on one side of the feeding box, thereby realizing the movement of the feeding box. 7. In this invention, during the movement, the pulleys at both ends of the connecting rod slide along the grooves opened on the guide frame. When the feeding box moves to the top of the support, the feeding box is changed from a vertical state to a horizontal state through two sets of pulleys, so as to pour the mud inside the feeding box into the discharge tongue and realize the feeding process of mud.

[0032] By adopting the above technical solution, during use, the slurry containing impurities is pumped into the slurry silo 2 by the pump body. When the first vibration motor 4 drives the slurry silo 2 to vibrate, the bottom of the mounting frame 3 cooperates with the top of the support frame 1 through the first spring 5 to ensure the vibration efficiency of the slurry silo 2 and avoid the slurry from clogging in the slurry silo 2. During the vibration process, the slurry falls onto the vibrating screen 6 below.

[0033] The feeding structure 13 includes a base 131 installed at the bottom; a bracket 132 is fixedly installed on the base 131; there are two brackets 132 arranged symmetrically; the brackets 132 are L-shaped; a guide frame 135 is fixedly installed on the side wall of each of the two brackets 132; the two guide frames 135 are provided with a groove 136 to facilitate the sliding of the pulley 141. Multiple support rods 137 are also installed between the two brackets 132; the two ends of the support rods 137 are movably connected to the brackets 132 via bearings; sprockets 140 are installed in the middle of the multiple support rods 137; and chains 138 are connected between the multiple sprockets 140.

[0034] In this embodiment, the purification component 10 includes a housing 101; one end of the housing 101 is fixedly installed on the side wall of the mounting housing 102; a drive motor 103 is fixedly installed on the side wall of the housing 101 away from the mounting housing 102; the output shaft of the drive motor 103 is fixedly installed on the rotating shaft 109 inside the housing 101. In this embodiment, a screw conveyor 1010 is installed at one end of the rotating shaft 109; a plurality of connecting rods 1011 are integrally provided at the other end of the rotating shaft 109. By adopting the above technical solution, the second vibration motor 11 fixedly installed at one end of the vibrating screen 6 drives the vibrating screen 6 to vibrate. At this time, the vibrating screen 6 is movably installed between the support column 7 and the second spring 8 and the support frame 1. This ensures that the vibrating screen 6 can screen larger particles of impurities. Since the vibrating screen 6 is set at an inclination, during the vibration of the vibrating screen 6, the screened impurities are automatically vibrated and transmitted downwards through the inclination angle of the vibrating screen 6, realizing the automatic separation of impurities from the vibrating screen 6, avoiding the impurities from clogging the vibrating screen 6 and the wear of the vibrating screen 6 due to long-term vibration.

[0035] Furthermore, a feed hopper 106 is fixedly installed on the top of the housing 101; the feed hopper 106 cooperates with the discharge pipe at the bottom of the separation chamber 9; the feed hopper 106 is located above the auger 1010. In this embodiment, the rotating shaft 109 is provided with a section of a connecting rod 1011, and a purification screen 12 is fixedly installed through the connecting rod 1011; the purification screen 12 is located inside the mounting shell 102; the mounting shell 102 is fixedly installed with the fixing frame. By adopting the above technical solution, the slurry after being screened by the vibrating screen 6 is transferred to the feed hopper 106 through the separation chamber 9. During the process of the drive motor 103 driving the rotating shaft 109 to rotate, the bottom of the feed hopper 106 is fixedly installed with the shell 101, so as to transfer the slurry into the shell 101. Then, the auger 1010 installed on the rotating shaft 109 is used to transfer the slurry forward, reducing the transfer speed of the slurry and making the slurry have a certain self-settling effect. Furthermore, as the auger 1010 rotates, the slurry is transferred to the purification screen 12 for further screening. The rotating shaft 109 is fixedly installed to the inner wall of the purification screen 12 via the connecting rod 1011, so that the purification screen 12 and the rotating shaft 109 rotate synchronously. During the rotation of the purification screen 12, the slurry is purified. At the same time, as the purification screen 12 rotates, the screened impurities are transferred to the discharge pipe 105 opened at the bottom of the fixed cover 108 at the other end for discharge. The purified slurry is then transferred to the collection chamber 104 at the bottom of the mounting shell 102.

[0036] In this embodiment, a fixing cover 108 is fixedly installed at the end of the mounting shell 102 away from the shell 101; the center of the fixing cover 108 is movably installed with the rotating shaft 109 via a bearing; and a discharge pipe 105 is fixedly installed on the bottom side wall of the fixing cover 108. A backwashing frame 107 is fixedly installed on the top of the mounting shell 102; the nozzle at the bottom of the backwashing frame 107 is located above the purification screen 12; a collection chamber 104 is fixedly installed inside the fixing frame at the bottom of the mounting shell 102. By adopting the above technical solution, when the sludge is further purified through the purification screen 12, one end of the backwashing frame 107 fixedly installed on the top of the mounting shell 102 is connected to the water source. The pump body draws clean water to realize the automatic cleaning of the nozzle installed at the bottom of the backwashing frame 107 and the surface of the purification screen 12. This effectively avoids the clogging of the purification screen 12 and also ensures the purification quality of the sludge by the purification screen 12.

[0037] In this embodiment, the slide 136 has two sets of pulleys 141 inside, and the two sets of pulleys 141 are fitted together with a connecting rod 142; the connecting rod 142 is fixedly installed to the feeding box 139 by a fixing block. In this embodiment, after the slurry to be processed is added, the feeding motor 134 installed on the top of the bracket 132 drives the support rod 137 to rotate, and the sprockets 140 on the multiple support rods 137 drive the chain 138 to rotate. The chain 138 is fixedly installed with the connecting rod 142 on one side of the feeding box 139, so as to realize the movement of the feeding box 139.

[0038] As a further technical solution of the present invention, a discharge tongue 133 is provided at one end of the top of the two brackets 132; the discharge tongue 133 is fixedly installed on both sides of the bracket 132; among the two brackets 132, a feeding motor 134 is installed on one side of one of the brackets 132; the output shaft of the feeding motor 134 passes through the support rod 137 at the top of the bracket 132 and is installed accordingly. In this embodiment, a fastener is provided on the side of the feeding box 139 near the connecting rod 142. The fastener is fastened and installed on the outside of the connecting rod 142. The outer surfaces of both sets of connecting rods 142 are fixedly connected to the chain 138.

[0039] By adopting the above technical solution, during the movement, the pulleys 141 at both ends of the connecting rod 142 slide along the grooves 136 opened on the guide frame 135. When the feeding box 139 moves to the top of the support 132, the two sets of pulleys 141 realize the transformation of the feeding box 139 from a vertical state to a horizontal state, so as to pour the mud inside the feeding box 139 into the discharge tongue 133, thus realizing the feeding process of mud.

[0040] The working principle of this invention is as follows: When the slurry to be processed is added to the feeding box 139, the feeding motor 134 installed on the top of the bracket 132 drives the support rod 137 to rotate. The sprockets 140 on the multiple support rods 137 drive the chain 138 to rotate. The chain 138 is fixedly installed with the connecting rod 142 on one side of the feeding box 139, so as to realize the movement of the feeding box 139. During the movement, the pulleys 141 at both ends of the connecting rod 142 slide along the grooves 136 opened on the guide frame 135. When the feeding box 139 moves to the top of the support 132, the two sets of pulleys 141 realize the transformation of the feeding box 139 from a vertical state to a horizontal state, so as to pour the mud inside the feeding box 139 into the discharge tongue 133 and realize the feeding process of mud. The slurry that has been fed into the slurry bin 2 falls into the slurry bin 2 through the discharge tongue 133. When the first vibration motor 4 drives the slurry bin 2 to vibrate, the bottom of the mounting frame 3 cooperates with the top of the support frame 1 through the first spring 5 to ensure the vibration efficiency of the slurry bin 2 and avoid the slurry from getting blocked in the slurry bin 2. The slurry falls onto the vibrating screen 6 below during the vibration process. The second vibration motor 11, which is fixedly installed at the bottom of one end of the vibrating screen 6, drives the vibrating screen 6 to vibrate. At this time, the vibrating screen 6 is movably installed between the support column 7 and the second spring 8 and the support frame 1. This ensures that the vibrating screen 6 can screen larger particles of impurities. Since the vibrating screen 6 is set at an inclination, during the vibration of the vibrating screen 6, the screened impurities are automatically vibrated and transmitted downwards at the inclination angle of the vibrating screen 6, so as to realize the automatic separation of impurities from the vibrating screen 6, and avoid the impurities from clogging the vibrating screen 6 and the wear of the vibrating screen 6 due to long-term vibration. After being screened by the vibrating screen 6, the slurry is transferred to the feed hopper 106 through the separation chamber 9. During the process of the drive motor 103 driving the rotating shaft 109 to rotate, the bottom of the feed hopper 106 is fixedly installed with the shell 101, so that the slurry is transferred into the shell 101. Then, the auger 1010 installed on the rotating shaft 109 is used to transfer the slurry forward, reducing the transfer speed of the slurry and giving the slurry a certain self-settling effect. As the auger 1010 rotates, the slurry is transferred to the purification screen 12 for further screening. The rotating shaft 109 is fixedly installed to the inner wall of the purification screen 12 via the connecting rod 1011, so that the purification screen 12 and the rotating shaft 109 rotate synchronously. During the rotation of the purification screen 12, the slurry is purified. At the same time, as the purification screen 12 rotates, the screened impurities are transferred to the discharge pipe 105 opened at the bottom of the fixed cover 108 at the other end for discharge. The purified slurry is transferred to the collection chamber 104 at the bottom of the mounting shell 102. When the sludge is further purified by the purification screen 12, one end of the backwashing frame 107 fixedly installed on the top of the housing 102 is connected to the water source. The pump body draws clean water to realize the automatic cleaning of the nozzle installed at the bottom of the backwashing frame 107 and the surface of the purification screen 12. This effectively avoids the clogging of the purification screen 12 and ensures the purification quality of the sludge by the purification screen 12.
