Description

Technical Field

[0001] The present invention belongs to the technical field of filtrate treatment, and in particular relates to a filtrate treatment device. Background Art

[0002] Filtrate refers to the liquid generated during the process of separating solid particles from liquid by using a filter press. During the filter press process, solid particles are placed on the filter medium, and then pressure is applied to allow the liquid to pass through the filter medium, thereby separating the solid particles. In order to purify and recycle the drilling fluid, after the drilling fluid is used up, it is usually treated by filter press. In order to further purify the filtrate, it is usually necessary to add a flocculant to the filtrate to make the solid particles in the filtrate agglomerate and settle, facilitating separation.

[0003] When pouring the flocculant into the filtrate, the following disadvantages exist: Since the content and properties of solid particles in the drilling fluid are closely related to factors such as formation conditions, rock types, and drilling fluid formulations, the content of solid particles in the filtrate obtained after the drilling fluid is treated by filter press varies greatly. However, the traditional filtrate treatment device lacks a mechanism for detecting the particle content inside the filtrate. When adding the flocculant to the treatment device, it is very difficult to control the amount of the added flocculant. As a result, there will be problems such as excessive addition of the flocculant, causing waste of the flocculant, and insufficient addition of the flocculant, where the particle content inside the filtrate is not completely removed. After using the flocculant to make the solid particles in the filtrate agglomerate and settle, it is necessary to separate the sediment and the liquid. Traditional pump suction is very likely to cause the sediment to be discharged together with the liquid, resulting in the liquid still containing sediment and the treatment effect of the filtrate being unsatisfactory.

[0004] Therefore, a filtrate treatment device is proposed to solve the above problems. Summary of the Invention

[0028] Now, the operation principle of the present invention is described as follows: By pressing an external button to open the solenoid valve inside the vertical pipe 4, the pressure filtrate stored in the liquid inlet box 2 will flow into the detection box 501 along the vertical pipe 4. When there are more solid particles in the pressure filtrate, the density of the pressure filtrate will increase. In the same mass of liquid, the greater the density, the greater the impact force when discharging the pressure filtrate of the same volume. The impact force of the denser pressure filtrate on the mesh plate 502 is also greater. The pressure filtrate passing through the mesh plate 502 will enter the treatment box 1 through the liquid inlet pipe 12 and wait for treatment. The mesh plate 502 drives the baffle 7, the bent frame 8 and the conductive block 9 to move downward through the baffle 7, so that the conductive block 9 contacts the resistance plate 11. The conductive block 9 is electrically connected to an external power supply, and the lower end of the resistance plate 11 is electrically connected to the first electromagnet 17. When the density of the pressure filtrate is greater, the farther the mesh plate 502 drives the baffle 7, the bent frame 8 and the conductive block 9 to move downward, so that the resistance connected to the circuit of the first electromagnet 17 is smaller. Under the condition of constant external voltage, the current flowing into the first electromagnet 17 is greater, so that the magnetic force generated by the first electromagnet 17 is greater. The first electromagnet 17 attracts the first permanent magnet plate 16, and the first permanent magnet plate 16 drives the adjusting plate 142 to move to the right. The adjusting plate 142 drives the triangular adjusting hole 18 on its surface to move to directly below the connecting pipe 13, so that the flocculant in the storage tank 3 falls into the adjusting box 141 through the connecting pipe 13 and the triangular adjusting hole 18 and enters the treatment box 1 through the support pipe 19. When there are more solid particles inside the pressure filtrate, the greater the density of the pressure filtrate, the greater the impact force of the pressure filtrate on the mesh plate 502 during the flowing process, the lower the position where the mesh plate 502 drives the conductive block 9 to move downward, so that the current flowing into the first electromagnet 17 is greater, the stronger the magnetic force of the first electromagnet 17, and the farther the position where the first electromagnet 17 drives the adjusting plate 142 to move to the right, so that the larger gap of the triangular adjusting hole 18 is located directly below the connecting pipe 13, and the greater the flow rate of the flocculant in the storage tank 3 flowing into the treatment box 1. Therefore, the amount of flocculant added to the treatment device can be automatically adjusted according to the content of particles in the pressure filtrate, which not only avoids the waste of flocculant but also ensures the treatment efficiency of particles in the pressure filtrate;After the pressure filtrate and the flocculant are injected into the treatment tank 1, the stirring motor 20 is controlled to work through an external button. The stirring motor 20 drives the stirring rod 21 to rotate. The stirring rod 21 stirs the pressure filtrate through the stirring plate 22 to fully mix the pressure filtrate and the flocculant. During the working process of the stirring rod 21, the induction cover 231 will be driven to rotate. The induction cover 231 drives the rotating column 232 to rotate through the placing plate 25, the rotating plate 24 and the spring, so that the rotating column 232 drives the induction plate 37 to rotate. When the solid particles in the flocculant and the pressure filtrate in the treatment tank 1 fully react, more agglomerated sediment will be generated below the pressure filtrate, thus increasing the density below the pressure filtrate. When the induction plate 37 stirs the agglomerated sediment, the resistance it receives will increase. The rotating plate 24 and the placing plate 25 need to compress the spring more to make the resistance received by the induction plate 37 equal. When the sediment in the pressure filtrate completely settles, the rotating plate 24 will drive the metal head 26 to rotate and contact the metal block 27. The metal head 26 is electrically connected to an external power source, and the metal block 27 is electrically connected to the second electromagnetic block 33. The second electromagnetic block 33 will generate a magnetic force when energized, thus adsorbing the second permanent magnet plate 32 to drive the moving frame 31 and the moving plate 30 to move leftward. The moving frame 31 will drive the copper plate 34 to move leftward, separating the copper plate 34 from the copper block 35. The copper plate 34 is electrically connected to an external power source, while the copper block 35 is electrically connected to the stirring motor 20. After they are separated, the stirring motor 20 will stop working. When the copper plate 34 moves leftward, it will contact the copper square 36. The copper square 36 is electrically connected to the lower electrical contact block 49. After the moving plate 30 moves leftward, it is fixed by locking with the tooth 67 between the positioning plate 66. When the copper plate 34 contacts the copper square 36, the current will be transmitted to the lower electrical contact block 49. The lower electrical contact block 49 is initially in contact with the lower connecting plate 50, and the lower connecting plate 50 is electrically connected to the driving motor 39, thus causing the driving motor 39 to work. The driving motor 39 drives the threaded cylinder 381 to rotate through the bevel gear assembly, and drives the external threaded sleeve 382 to move downward through thread cooperation. When the external threaded sleeve 382 drives the floating block 55 and the lower end of the folding hose 41 to move below the liquid level, under the action of the buoyancy of the liquid, the floating block 55 will drive the sliding block 53 to move upward. When the sliding block 53 drives the connecting plate 56 to contact the connecting block 57, since the connecting block 57 is electrically connected to an external power source and the connecting block 57 is electrically connected to the third electromagnetic block 47, when the connecting plate 56 contacts the connecting block 57, the external power source will flow into the third electromagnetic block 47, thus causing the third electromagnetic block 47 to generate magnetism. The third electromagnetic block 47 will adsorb the third permanent magnet plate 46, and the third permanent magnet plate 46 drives the bottom plate 48 to move upward through the lifting plate 45 and the insertion rod 44. The bottom plate 48 drives the upper and lower electrical contact blocks 49 to move upward. When the lower electrical contact block 49 separates from the lower connecting plate 50, the circuit of the driving motor 39 will be disconnected, causing the driving motor 39 to stop working, and the external threaded sleeve 382 will stop moving downward.And when the power-on contact block 49 moves upward, it will contact the upper connecting plate 51. The upper contact block 49 is electrically connected to an external power source, and the upper connecting plate 51 is electrically connected to the pump 40, so that the pump 40 starts to work. The pump 40 transports the settled liquid out of the treatment tank 1 through the folding hose 41. And when the liquid level in the treatment tank 1 drops, the floating block 55 will drive the power connection plate 56 and the power connection block 57 to separate under the action of gravity, thus disconnecting the circuit of the third electromagnet 47. The lifting plate 45 drives the bottom plate 48 to move downward under the pulling force of the spring. The bottom plate 48 drives the upper contact block 49 to separate from the upper connecting plate 51, thus disconnecting the circuit of the pump 40 and stopping the pump 40. And the bottom plate 48 will drive the lower contact block 49 to contact the lower connecting plate 50, thus restoring the circuit of the drive motor 39 and making the drive motor 39 work, controlling the external thread sleeve 382 to continue moving downward, and repeating the above steps; When the external thread sleeve 382 has transported all the filtered liquid, the external thread sleeve 382 will contact the agglomerated sediment, and thus will adsorb the agglomerated sediment. Since the density of the agglomerated sediment is very large, when the pump 40 adsorbs the sediment with a constant adsorption force, the folding hose 41 and the internal part will be subjected to a relatively large suction force. The pneumatic cylinder 60 is connected to the folding hose 41. When the internal pressure of the folding hose 41 increases, the air pressure on the right side of the piston plate 62 inside the pneumatic cylinder 60 will also increase, and the external gas will enter the pneumatic cylinder 60 through the air pressure holes, causing the piston plate 62 to move to the right. The piston plate 62 will drive the induction block 63 to contact the induction sheet 64. The induction block 63 is electrically connected to an external power source, and the induction sheet 64 is electrically connected to the PLC controller, thus giving an electrical signal to the PLC controller. The PLC controller first controls the drive motor 39 to rotate reversely, controls the external thread sleeve 382 to return to its original position, and will open the control valve 59 inside the discharge pipe 58, so that the agglomerated sediment is discharged from the discharge pipe 58, ensuring the effect of solid-liquid separation.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
