Abstract
Description
Technical Field
[0001] This invention belongs to the field of mud utilization technology, specifically relating to a device for recycling drilling mud for bored piles. Background Technology
[0002] Chinese patent CN220779301U discloses a drilling mud recycling device for bored piles. A cylinder can be rotated by a geared motor and a vertical rod. Solid impurities in the mud can be filtered and separated by the cylinder and screen holes. The filtered mud can be discharged and recycled through a discharge pipe. A small motor, a threaded rod and a threaded sleeve can drive a sliding plate to move upward. The sliding plate drives a piston plate to move upward through a push rod. Solid impurities can be pushed to the left and fall into a collection box by an electric telescopic rod and a push plate.
[0003] However, this device separates mud by centrifugation through a rotating cylinder. But because the sieve holes on the surface of the cylinder are all the same size, it can only screen mud particles of one diameter, and the effect of rotational centrifugation screening is poor. After the existing mud centrifuge is used for mud recycling, a lot of mud adheres to the inner wall of the storage tank. The commonly used flushing pipe has a fixed position, which results in a better flushing effect in the storage tank at the pipe opening, while the flushing effect of the storage tank at the later position becomes worse and worse. It is impossible to flush the storage tank thoroughly after each use, which affects subsequent use. Summary of the Invention

The front side of the connecting frame 6 is rotatably connected to two feeding plates 62.

The mounting base 611 is fixedly installed on the connecting frame 6, and the support rod 612 is rotatably connected inside the mounting base 611. The support rod 612 is adapted to the slot 621. The two sets of feeding plates 62 correspond one-to-one with the first vibrating screen 8 and the second vibrating screen 9. By inserting the support rod 612 into different slots 621, different feeding angles can be adjusted.
[0039] The hydrocyclone, vibrating motor connecting plate, first vibrating screen, second vibrating screen, vibrating spring, slurry pump, level float box, hydraulic cylinder, first motor, sprinkler head, and second motor in this case are existing technologies. Any of these components, as long as they meet the requirements of this case, are acceptable and not limited to a single model. Before wiring the hydrocyclone, the power supply must be disconnected, and a voltage tester must be used to confirm no power. The power lines must be clearly identified: the live wire connects to the equipment terminals, and the neutral and ground wires connect to dedicated terminals. Copper sheets should be used to insulate multiple wires to avoid excessive contact resistance. The terminal screws must be tightened, and the metal casing must be reliably grounded to prevent… Leakage current; if electrically controlled, the control lines must be connected according to the circuit diagram to ensure normal signal transmission. After wiring, use a multimeter to check for short circuits and open circuits in the circuit. After confirming that everything is correct, power on for testing. The working principle of the hydrocyclone is as follows: after the mixture enters the hydrocyclone tangentially, a high-speed rotating vortex is formed inside. Since the density of solid particles is greater than that of liquid, they are thrown against the wall of the device by centrifugal force and sink along the wall surface, and finally discharged through the bottom outlet. The liquid, due to its lower density, gathers towards the center and rises along the central axis, and is discharged through the overflow outlet. The feed inlet is designed as a tangential inlet, which can quickly form a rotating flow field and enhance the centrifugal force effect. The cone ratio and angle cone ratio of the inner diameter of the hydrocyclone are optimized to ensure maximum tangential velocity and energy utilization efficiency.
[0040] The specific types or circuit structures of the controllers for the electrical components mentioned in this application, as well as the circuit connection relationships between the electrical components and the accurate coordinated control of multiple power components, are all prior art. Therefore, the above content will not be elaborated upon in this application.
[0041] Working principle: The electrical components mentioned in this application are all connected to an external power supply and control switch during use. After the invention is installed, first check the installation, fixation and safety protection of the invention, and then it can be used. Before use, the user first inserts the support rod 612 into the corresponding slot 621, so that the feeding plate 62 rotates to the preset feeding angle.
[0042] In operation, external slurry is fed to the second vibrating screen 9 through the feed pipe 18. The screen is then vibrated linearly by a vibrating motor, separating large particles of slag. The screened slurry enters the storage tank 2. The slurry pump 15 draws slurry from the storage tank 2 through the feed pipe 16 and discharges it through the discharge pipe 17 into the tangential feed port of the hydrocyclone 5. The hydrocyclone 5 separates the solid and liquid components, discharging the separated mud and sand particles from the bottom outlet of the hydrocyclone 5. These particles fall through the bottom outlet baffle 19 onto the first vibrating screen 8, where they are dewatered and screened out. The slurry separated by the hydrocyclone 5 is discharged into the intermediate storage tank 3 through the overflow connection pipe 20, and then returns to the storage tank 2 through the replenishment pipe 21 for circulation and purification. When the slurry level in the storage tank 2 rises, the slurry will drive the level float 2. 4. Move upwards until the level float 24 blocks the replenishment port. At this time, the level sensor in the slurry storage tank 2 directly measures the change in liquid level and converts it into an electrical signal. The electrical signal is transmitted to the controller of the hydraulic system through a cable or bus. The controller adjusts the oil flow, pressure or direction of the hydraulic cylinder 27 through components such as solenoid valves and proportional valves according to the received liquid level signal, thereby controlling the movement speed, position or force of the piston. This causes the hydraulic cylinder 27 to drive the side plate 26 and the sealing baffle 25 to move upwards. At this time, the slurry in the middle storage tank 3 is discharged through the tail outlet pipe 22 and returns to the external slurry tank to achieve external circulation. When the slurry in the slurry storage tank 2 drops, the level float 24 moves downwards. After the level sensor detects the change in liquid level, it controls the hydraulic cylinder 27 to drive the sealing baffle 25 downwards, separating the replenishment port from the tail outlet to achieve internal circulation.
[0043] After the mud separation device is used, the user connects the inlet pipe 1014 to an external water source and water pump, allowing water to flow into the sprinkler head 1013 to flush the slurry storage tank 2. Then, the user starts the first motor 107 and the second motor 1015. The first motor 107 drives the worm gear 108 to rotate, which meshes with the worm wheel 1011. The worm wheel 1011 drives the rotating drum 1010 to rotate, which in turn drives the turntable 1012 and the sprinkler head 1013 to rotate, increasing the water spraying range. The second motor 1015 drives the first rotating shaft 1016 to rotate, which in turn drives the first pulley 1017 to rotate. The first pulley 1017 drives the belt 1020 and the second pulley 1019 to rotate. As the belt 1020 moves, it drives the belt clamp 1022 and the vertical plate 1021 to move, thereby driving the moving wheel 102 to move linearly within the track 101, thoroughly flushing the slurry storage tank 2.
[0044] After each use of the device, staff regularly clean and maintain it, promptly removing any mud adhering to the track 101 to prevent prolonged adhesion from causing corrosion.
