Description

Technical Field

[0001] The invention relates to the technical field of oil-based rock cuttings mixing equipment system at a drilling site, and more particularly to a rock cuttings mixing system. Background Art

[0002] The oil-based mud cuttings separation and mixing equipment system currently in use on site, the dry cuttings and thick slurry separated from the dryer and centrifuge are either transported to the cuttings storage tank through their own screw conveyors, or the centrifuge and dryer are transported to the cuttings storage tank through a common screw conveyor, and then mixed and transported by an excavator.

[0003] However, neither of the above two methods can achieve automatic mixing of dry materials and thick materials. A special excavator is required to mix the materials in the cuttings tank until they are mixed into wet materials (dry materials containing moisture), which are then loaded by the excavator and transported to a special collection point. In other words, mixing and transporting by excavator will increase the cost of the excavator and the excavator operator, and using multiple screw conveyors for transportation will also increase unnecessary costs. In addition, if an external curing agent is used for mixing to reduce the risk of environmental pollution during transportation, the purchase cost of the curing agent will be increased.

[0004] Therefore, providing a rock cuttings mixing system with reduced costs is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0005] In view of this, the present invention provides a rock cuttings mixing system, which can not only reduce the risk of environmental pollution during transportation, but also greatly reduce operating costs.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] A rock cuttings mixing system comprises a hollow tank, a partition, a spin dryer, a centrifuge, a screw conveyor, a plurality of first vibration motors, a plurality of second vibration motors and a plurality of third vibration motors;

[0008] The interior of the tank body is divided into a dry rock cuttings bin and a thick slurry bin by the vertically arranged partition; the bottom of the dry rock cuttings bin is inclined and has a plurality of first discharge ports; the bottom of the thick slurry bin is inclined and has a plurality of second discharge ports;

[0009] The spin dryer is fixed on the top of the dry rock cuttings bin and is in communication with the interior thereof;

[0010] The centrifuge is fixed on the top of the thick pulp bin and communicated with the interior thereof;

[0011] The screw conveyor is placed below the dry rock cuttings bin and the thick slurry bin, and corresponds to the first discharge port and the second discharge port;

[0012] A plurality of the first vibration motors are mounted on the top of the tank body;

[0013] A plurality of the second vibration motors are respectively installed at the bottom of the dry cuttings bin and the bottom of the thick slurry bin;

[0014] The plurality of third vibration motors are respectively installed at the plurality of first discharge ports and the plurality of second discharge ports.

[0015] By adopting the above scheme, the beneficial effects of the present invention are:

[0016] The tank body is divided into a dry rock cuttings bin and a thick slurry bin by a partition. The dryer is directly installed on the top of the dry rock cuttings bin and connected to each other. The centrifuge is directly installed on the top of the thick slurry bin and connected to each other. Due to the gravity of the rock cuttings particles themselves, the discharges of the dryer and the centrifuge will automatically fall into their respective bins, thereby saving the cost of two screw conveyors; at the same time, when the bottoms of the dry rock cuttings bin and the thick slurry bin are tilted, and under the action of the first vibration motor, the second vibration motor and the third vibration motor, the dry rock cuttings and the thick slurry will fall into the screw conveyor through the first discharge port and the second discharge port respectively for mixing. In this process, the dry rock cuttings thrown out by the dryer can be used as a dry material additive and mixed with the thick material thrown out by the centrifuge, and finally become slightly dry wet material to be transported to the designated location, reducing the risk of environmental pollution during transportation. At the same time, the rental fees of the excavator and the operator must also be saved, reducing the operating costs; in addition, the use of the dry rock cuttings thrown out by the dryer as a curing agent does not violate the method of incremental use of external curing agents, and also saves the cost of purchasing curing agents.

[0017] Furthermore, the length ratio of the dry cuttings bin to the thick slurry bin is 1:1 or 2:1 or 3:1.

[0018] Furthermore, the bottom of the dry cuttings bin and the bottom of the thick slurry bin have the same inclination direction, and the inclination angle of the bottom of the dry cuttings bin and the bottom of the thick slurry bin are the same, both forming an angle of 5° with the horizontal plane.

[0019] The beneficial effect of adopting the above-mentioned further technical solution is that during the accumulation process of dry rock chips and thick slurry in their respective chambers, due to the 5° bottom inclination angle, under the combined effect of their own gravity and vibration, the dry rock chips and thick slurry will automatically slide down to the first discharge port and the second discharge port, and then reach the screw conveyor for automatic output.

[0020] Furthermore, there are four first discharge ports, which are arranged at equal intervals at the bottom of the dry cuttings bin; there are two second discharge ports, which are arranged at equal intervals at the bottom of the thick slurry bin.

[0021] Furthermore, the plurality of the first vibration motors and the plurality of the second vibration motors are all horizontal vibration motors.

[0022] Furthermore, the number of the second vibration motors is six, and the six second vibration motors are respectively installed at the bottom of the dry cuttings bin near the first discharge port and at the bottom of the thick slurry bin near the second discharge port.

[0023] The beneficial effect of adopting the above further technical solution is that by driving the second vibration motor, when the tank is finally cleaned, the remaining few rock chips or thick slurry will be vibrated and slide down to their respective discharge ports, ensuring that the entire tank body is finally cleaned.

[0024] Furthermore, the plurality of third vibration motors are all vertical vibration motors; the number of the third vibration motors is six, and the six third vibration motors are respectively installed at the four first discharge ports and the two second discharge ports.

[0025] The beneficial effect of adopting the above further technical solution is that the rock cuttings near the discharge port can be continuously vibrated out.

[0026] Furthermore, it also includes six gates; the six gates are respectively installed on the four first discharge ports and the two second discharge ports.

[0027] The beneficial effect of adopting the above-mentioned further technical solution is that the degree of opening and the number of open gates of the six gates are controlled by the gates to achieve the mixing wetness and dryness to meet the transportation conditions.
