Description

Technical Field

[0001] The utility model relates to the technical field of fluid loss reducer production, in particular to a batching and mixing device for producing a powdered fluid loss reducer for drilling fluid. Background Art

[0002] Fluid loss reducer is used during the drilling process. Due to the effect of pressure difference, the water in the drilling fluid will inevitably filter through the well wall into the formation, causing the drilling fluid to lose water. As the water enters the formation, the clay particles in the drilling fluid will adhere to the well wall to form a "filter cake", forming a filter cake well wall. Since the filter cake well wall is much denser than the original well wall, it prevents further water loss of the drilling fluid on the one hand, and protects the well wall on the other hand. However, in the process of forming the filter cake well wall, excessive water loss, excessive filter cake thickness, and fine clay particles entering the formation with the water will affect normal drilling and cause damage to the formation;

[0003] The traditional mixing device for producing powdered fluid reducer for drilling fluid is usually a mixing barrel. The staff pours the weighed fluid reducer raw materials into the mixing barrel according to the proportion, and then drives the stirring blade to rotate by the motor to fully mix the fluid reducer raw materials to achieve the mixing of the fluid reducer ingredients, or the raw materials are quantitatively added through the feeding trough, but the feeding trough cannot adjust the volume;

[0004] This type of mixing device for producing powdered fluid loss reducer for drilling fluid has the following disadvantages: each raw material needs to be weighed and mixed in proportion before each mixing of the fluid loss reducer; the feeding trough for quantitative feeding cannot adjust the volume, the operation is inconvenient, the adaptability and flexibility are poor, and the stirring blades are inconvenient to disassemble and maintain. Therefore, we propose a mixing device for producing powdered fluid loss reducer for drilling fluid. Utility Model Content

When the stirring blade 343 needs to be maintained, the shaft body of the stirring blade 343 can be squeezed inward by hand to squeeze and shrink the spring 344, and then rotated 90 degrees to one side so that it cannot be fixed in the slot 345, and the stirring blade 343 can be removed. After the maintenance is completed, the plug block 346 at the front end of the stirring blade 343 is aligned with the slot 345 and inserted into it, and inserted to the bottom of the slot 345.

[0032] Among them: the input end of the single-chip computer 2 is electrically connected to an external power supply, and the ingredients of the filtrate reducer are prepared by quantitative feeding, which eliminates the step of repeated weighing. The volume of the feeding trough 324 can be adjusted, and the corresponding volume can be adjusted according to different ratios of the raw materials. The operation is more convenient and flexible, and the stirring blade 343 is easy to disassemble and convenient for maintenance.

[0033] The working principle of a batching and mixing device for producing a powdered fluid loss reducer for drilling fluid provided by the utility model is as follows: when it is necessary to produce a fluid loss reducer, since there are six feeding components 32, the fluid loss reducer production staff needs to first adjust the volume of the feeding troughs 324 in different feeding components 32 according to the raw material ratio to prevent the problem of incorrect batching. Since the surface of the screw 327 can be marked with scales in advance, the screw 327 penetrates into the threaded hole and the corresponding scale will lift the corresponding height of the adjustment block 325, thereby determining the volume of the feeding trough 324 after adjustment. First, turn the knob 328 to drive the screw 327 to rotate, so that the screw 327 rotates to the threaded hole. The deep movement drives the squeezing block 326 to slide to the right side of the rotating disk 322. At this time, the inclined surface of the upper end of the squeezing block 326 contacts and squeezes the inclined surface of the lower end of the adjusting block 325, so that the adjusting block 325 slides upward to reduce the volume of the feeding trough 324, and then the fluid loss agent raw materials are poured into the lower hopper 323 respectively, and then the first motor 33 and the angle sensor 6 are turned on by the single-chip microcomputer 2. The first motor 33 drives the rotating disk 322 to rotate. When the feeding port at the upper end of the feeding trough 324 is transferred to the lower end of the feeding port of the lower hopper 323, the fluid loss agent raw materials will automatically fall into the feeding trough 324. When a feeding trough 324 is full of fluid loss agent raw materials, the first motor 33 drives The rotating disk 322 rotates to load the next feeding trough 324. When the feeding trough 324 rotates to the bottom of the feeding disk 321, the raw materials in the feeding trough 324 will fall into the discharge hopper at the lower end of the feeding disk 321, and finally fall into the batching barrel 1. Since the angle sensor 6 is sleeved on the outer surface of the rotating shaft, the number of rotations of the rotating disk 322 can be determined according to the angle recorded by the angle sensor 6, so as to grasp the amount of each raw material added. At this time, the second motor 341 is turned on by the single-chip microcomputer 2, and the second motor 341 drives the stirring blade 343 to fully stir the filtrate reducer raw material in the batching barrel 1 for use. When the filtrate reducer raw material in the batching barrel 1 is stirred The filtrate reducer can be taken out through the discharge port door 5 at the bottom of the batching barrel 1. If the stirring blade 343 needs to be maintained, the shaft of the stirring blade 343 can be squeezed inward by hand to squeeze and shrink the spring 344, and then rotated 90 degrees to one side so that it cannot be fixed in the slot 345, and then the stirring blade 343 can be removed. After the maintenance is completed, the plug block 346 at the front end of the stirring blade 343 is aligned with the slot 345 and inserted into it, and inserted to the bottom of the slot 345. At this time, the spring 344 is squeezed and shrunk, and then the stirring blade 343 is rotated 90 degrees to one side, so that the plug block 346 is fixed at the bottom of the slot 345, and the stirring blade 343 is firmly fixed by the rebound force of the spring 344.
