Embodiment 1

[0015] Embodiment 1 provides a solid-liquid separator in which pneumatic vibrators are arranged in a nine-square pattern, and its structure will be described in detail below.

[0016] refer to figure 1 and figure 2 , the solid-liquid separator includes a transmission mechanism, a vibration mechanism and a charging box 3.

[0017] The transmission mechanism comprises a transmission case 10, a drive motor 11, a main rotating roller 130, three auxiliary rotating rollers 131, a transmission belt 14 and a screen cloth 15,

[0018] The main rotating roller 130 and the three auxiliary rotating rollers 131 are arranged horizontally at the four corners of the transmission case 10 respectively, and the four points of the vertical section are connected from head to tail in order to form a trapezoid with the upper bottom facing downward and the lower bottom facing upward.

[0019] The output shaft of the driving motor 11 is provided with a bevel gear, and the main rotating roller 130 i...

Abstract

The invention discloses a solid-liquid separator. The solid-liquid separator comprises a transmission mechanism, a vibration mechanism and a charging box. The horizontal displacement is provided by the transmission mechanism to realize the movement of a solid-liquid mixture in the horizontal direction; the vertical displacement is provided by the vibration mechanism, a vibration bracket is fixedlyarranged on the transmission mechanism, a pneumatic exciter is arranged on the vibration bracket, the pneumatic exciter is ventilated by an air path pipeline, and the vibration of the solid-liquid mixture in the vertical direction is realized; and finally, a liquid phase enters the charging box, and solid particles continue to move forwards with a screen and finally fall into the material pickingend. According to the solid-liquid separator, the structural stability and the consistency of the amplitude and vibration frequency are effectively kept, and it is further ensured that the amplitudeand vibration frequency of each area of the screen are consistent, the working noises are reduced, the screen is effectively prevented from blocking, and the screening effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of oil drilling solid-liquid separation, in particular to a solid-liquid separator. Background technique [0002] The solid-liquid separator is optimized on the basis of the vibrating screen, which can separate the solid and liquid phases. Its screening effect is obviously better than that of the traditional vibrating screen. The pneumatic vibrator is a very important component of the solid-liquid separator, and the selection, quantity and distribution of the pneumatic vibrator have a significant impact on its performance. [0003] At present, the common vibrating screen exciters usually use low-frequency vibrators with a frequency below 50HZ. It is necessary to select the number of exciters and determine the layout method according to the mode shape. The low-frequency exciters of this common vibrating screen are generally installed on the screen. Outside the box, the entire vibrating screen vibrates togeth...
