Description
Technical Field
The utility model relates to the technical field of inclination adjustment of a screen box of a drilling fluid vibrating screen, in particular to a mechanical synchronous inclination adjustment device of the drilling fluid vibrating screen.
Background
The inclination angle of the screen box of the drilling fluid vibrating screen is required to be adjusted within a certain inclination angle range in the running process according to the size of materials and the change of parameters, so that the screening efficiency is improved to a greater extent, and the occurrence of emergency conditions such as slurry leakage and the like is avoided. The view angle of the screen surface of the vibrating screen and the horizontal direction is also called the screen surface inclination angle of the vibrating screen, the slope of the screen surface is large, the retention time of materials on the screen surface is short, the discharge of oversize materials is facilitated, the output in unit time is large, but because the material layer moves forward on the screen surface at a higher body-building speed, the probability of particulate matter penetration is reduced, and the screening high efficiency is reduced. The smaller the inclination angle of the screen surface of the vibrating screen is, the longer the material stays on the screen surface, and although the mass interconversion rule is solved, the material has a large number of probability of passing through the screen, so that the screening cost can be increased.
In the specific processing process, the inclination angle of the screen surface can be operated according to the actual characteristics of the materials, under the general condition, the inclination angle of the screen surface is about 0-10 degrees, and the inclination angle of the screen surface of the vibrating screen can be moderately reduced for the materials with higher viscosity or other materials which are difficult to screen, so that the screening effect of the vibrating screen is improved.
The inclination angle adjustment modes of the drilling fluid vibrating screen are various, and the drilling fluid vibrating screen is usually provided with a manual adjustment device of double-side (uncorrelated) screw rods, a hydraulic lifting adjustment device, an electric push rod, a manual positive and negative screw rod and the like.
A disadvantage of a double sided (unassociated lead screw drive) manual adjustment device is that both sides must be operated simultaneously by two persons or a single person adjusts a smaller position on one side and then to the other side for adjustment. This is cumbersome and inconvenient to operate.
The hydraulic lifting adjusting device adopts a manual or electric pump to drive the oil cylinder pistons at two sides to stretch out and draw back, so that the two sides synchronously ascend or descend. However, a lock pin is needed to be inserted after the operation, otherwise, the inclination angle of the screen box is slowly reduced due to internal leakage of the oil cylinder in a vibrating environment, and the sealing ring of the oil cylinder is gradually invalid, so that the service life is shortened.
The electric push rod and the manual positive and negative screw rod are all that the screw rod nut is always pulled, and harmful transverse vibration is easily caused.
