Abstract

The utility model relates to a mud buffer. The mud buffer is characterized in that a buffer barrel is sealingly fixed on a chassis through a reinforcing plate, a mud inlet and outlet connector are arranged on a buffer barrel wall, a buffer plate is fixed on upper ends of a mud inlet and outlet connector located inside the buffer barrel and separates the buffer barrel into an upper chamber and a lower chamber, small holes for allowing the upper chamber to be communicated with the lower chamber are uniformly distributed on the buffer plate, and a cover plate is sealingly fixed on an upper end of the buffer barrel. The mud buffer has the advantage of eliminating the shaking caused by big range of change of mud pump flow pulses.

Description

A kind of mud buffer

Technical field

The utility model relates to a kind of mud buffer, is particularly suitable for freezing hole construction slurry pump pipeline and uses.

Background technique

Freezing hole construction is the working procedure in early stage that freezes refrigeration engineering, and the height of freezing hole construction quality directly has influence on follow-up construction quality and the construction cost that freezes the refrigeration construction.In the pit shaft freezing drilling construction, produce friction because slurry pump flow pulse change amplitude causes greatly the serious vibrations of mud channel and ground, equipment, and cause at the bottom of the drilling process mesopore not steadily to pressing, making to hole easily produces deflection.

Summary of the invention

In order to overcome the shortcoming of prior art, the utility model provides a kind of mud buffer, and it can eliminate the vibrations that bring greatly because of slurry pump flow pulse change amplitude.

The technical scheme in the invention for solving the technical problem is: on chassis, by stiffening plate, seal fixedly buffer barrel, on the buffer barrel wall, have mud into and out of joint,, in buffer barrel mud into and out of joint, the fixing cushion plate in upper end, cushion plate is divided into epicoele and cavity of resorption by buffer barrel, the uniform aperture that epicoele and cavity of resorption are communicated on cushion plate, the upper end sealing securing cover plate of buffer barrel.

The utlity model has following advantages: 1), utilize air in closed space as the buffering medium, absorb, eliminate the vibrations that bring greatly because of slurry pump flow pulse change amplitude, and cause at the bottom of the drilling process mesopore not steadily to pressing, improve the drilling construction quality, and reduce hole and leak; 2), can eliminate vibrations and the friction of mud channel, greatly extend the working life of mud channel high-voltage tube, eliminate the potential safety hazard of bringing because of the mud channel vibrations.

The accompanying drawing explanation

Below in conjunction with drawings and Examples, this utility model is further illustrated.

Fig. 1 is the utility model plan view;

Fig. 2 is the utility model plan view.

Embodiment

As shown in Figure 1, 2, seal fixedly buffer barrel 4 by stiffening plate 2 on chassis 1, mud is arranged into and out of

joint

3,12 on buffer barrel 4 walls, the interior mud of buffer barrel 4 is fixing cushion plate 5 into and out of the upper end of

joint

3,12, cushion plate 5 is divided into epicoele 10 and cavity of resorption 11 by buffer barrel 4, the uniform aperture 8 that epicoele 10 and cavity of resorption 11 are communicated on cushion plate 5, the upper end sealing securing cover plate 9 of buffer barrel 4.

Be fixed with pressure gauge 7 on described cover plate 9, pressure gauge 7 stretches into the epicoele 10 of buffer barrel 4.

Between described cover plate 9 and buffer barrel 4, by gusset 6, reinforce.

Described cushion plate 5 can be replaced with the multilayer fine-structure mesh.
