Abstract

The invention provides a wedged double-layer balance mud screen for a cast-in-place pile mud purification unit and relates to engineering machinery. A guide device disposed in a riddle feeding cavity comprises an upper guide plate and a lower guide plate. The upper guide plate is fixed on the inner side of a tail back plate of a screen box and is inclined to the tail back plate of the screen box at a certain angle. The lower guide plate is fixed on a partition and is inclined to the same at a certain angle. The guide device relieves waterhead thrust of mud water entering a riddle layer when mud is fed by a mud pump, waterhead is disabled to directly impact on a riddle plate, and the mud is prevented from splashing out of a screen outlet. A plurality of triangular waterstop strips are disposed above a sieve plate and the riddle plate respectively, two ends of each waterstop strip are welded on a screen plate frame, the waterstop strips effectively decrease running speed of the mud on the sieve plate and increases vibrating time of the mud on the sieve plate, and the degree of water separation of the mud by the vibrating screen is increased.

Description

The bored concrete pile mud purification treating apparatus double-deck balance mud shaker of wedge shape
Technical field
The present invention relates to a kind of engineering machinery, be specifically related to the mud purification treating apparatus double-deck balance mud shaker of wedge shape that bored concrete pile uses in work progress.
Background technology
The mud conditioning device, is more and more used in pile foundation foundation construction process as the purified treatment of building mud.This class mud conditioning device mainly is made up of vibratory sieve and cyclone two parts.Vibratory sieve divides two groups of thin sieve plate and scalping plates again.At present the vibratory sieve of using is the vibratory sieve of transplanting common traditional structure, and that this class vibratory sieve mainly is the pure solid formation of ore dressing and letter sorting different brackets is used.Because building mud is the pasty state that water content is big, solid phase particles is more tiny and viscosity is higher, intrinsic vibratory sieve is difficult to handle, and mainly is presented as:
1, the effluent water content was bigger after sieve shook, and was not easy to the dried transportation of slag charge.
When 2, mud is carried pan feeding by slush pump, head directly is flushed on the scalping plate, causes to spill the sieve discharging opening, uses on-the-spotly can form new pollution and potential safety hazard again.
